FORWARD LOOKING

STATEMENTS

This

Annual

Report,

including

the

exhibits

attached

hereto

and

incorporated

herein

may

contain

“forward-looking

statements”

within

the

meaning

of

applicable

Canadian

and

United

States

securities

laws.

All

statements

other

than

statements of historical

fact are

forward-looking statements. The

forward-looking statements contained

in this

Annual Report

are made

only as

of the

date hereof.

The forward-looking

statements contained

in the

exhibits incorporated

by reference

into this Annual

Report are made

only as of

the respective dates

set forth in

such exhibits. The

Registrant does

not have,

or undertake,

any obligation

to update

or revise

any forward

-looking statements

whether as

a result

of new

information,

subsequent events or otherwise, unless otherwise required

by law.

Generally, forward-looking information can be

identified by the

use of forward-looking terminology

such as “plans”,

“expects”

or

“does

not

expect”,

“is

expected”,

“budget”,

“scheduled”,

“estimates”,

“forecasts”,

“intends”,

“anticipates”

or

“does

not

anticipate”, or “believes”,

or variations of

such words and

phrases or statements

that certain actions,

events or results

“may”,

“could”, “would”, “might” or “will be taken”, “occur”

or “be achieved”. Forward-looking statements are

based on a number of

material

assumptions,

which

management

of

the

Registrant

believe

to

be

reasonable,

including,

but

not

limited

to,

the

Registrant’s ability to generate sufficient

cash flow from operations and obtain financing,

if needed, on acceptable terms or

at

all;

the

general

economic,

financial

market,

regulatory

and

political

conditions

in

which

the

Registrant

operates;

the

interest of potential purchasers in

the Registrant’s products; anticipated and unanticipated costs; the government

regulation

of the Registrant’s activities and products; the timely receipt of any required regulatory

approvals; the Registrant’s ability to

obtain

qualified

staff,

equipment

and

services

in

a

timely

and

cost

efficient

manner;

the

Registrant’s

ability

to

conduct

operations in a safe,

efficient and effective

manner; and the Registrant’s

expansion plans and

timeframe for completion

of

such plans

Forward-looking

information

is subject

to

known

and

unknown

risks,

uncertainties

and

other

factors

that

may

cause

the

actual

results,

level

of

activity,

performance

or

achievements

of

the

Registrant

to

be

materially

different

from

those

expressed

or

implied

by

such

forward-looking

information.

Although

the

Registrant

has

attempted

to

identify

important

factors that could cause actual results to differ materially from those contained in forward-looking statements, there may be

other factors that cause results not to be as

anticipated, estimated, intended or projected. There

is no assurance that such

statements will

prove to

be accurate,

as actual

results

and future

events could

differ materially

from those

anticipated

in

such

statements.

Accordingly,

readers

should

not

place

undue

reliance

on

forward-looking

statements.

Readers

should

carefully consider the maters as

further discussed under the heading "Risk

Factors" in the Registrant’s Annual

Information

Form for the year ended December 31, 2020, which is

filed as Exhibit 99.1 hereto and incorporated by reference

herein

The forward-looking statements

otherwise

specified.

Except as

required

by

applicable

securities

law,

the

Registrant

undertakes

no

obligation

to

update

publicly

or otherwise

revise

any forward

-looking

statements

or the

foregoing

list

of

factors

affecting

those statements, whether as

a result of

new information, future events

or otherwise or

the foregoing lists of

factors affecting

Jumpstart Our

Business Startup

Act (the

enacted on

April 5, 2012,

the

Registrant qualifies as

an “emerging growth

advantage of certain

exemptions

from

various

reporting

requirements

that

are

applicable

to

other

public

companies

that

are

not

EGCs.

Specifically,

the JOBS

Act defers

the

requirement

to

have

the

assess

the

internal

control

over

financial

reporting

under

Section 404(b) of

the

statements

”) within the meaning

legislation. All statements

other than statements of

historical fact

contained in this AIF

are forward-looking statements,

including, without limitation,

the Company’s statements

regarding its

products and services; the execution of its growth strategy; relations with suppliers and

customers; future financial position;

business strategy; potential acquisitions; potential

business partnering; litigation; and plans

and objectives. In certain

cases,

forward-looking

statements

can

be

identified

by

the

use

of

words

such

as

“plans”,

“expects”

or

“does

not

expect”,

“is

expected”, “budget”, “scheduled”,

“estimates”, “forecasts”, “intends”,

“anticipates” or “does

not anticipate”, or

“believes”, or

variations of such words and phrases

or state that certain actions,

events or results “may”, “could”,

“would”, “might” or “will

be taken”, “occur” or “be achieved” and similar words or the negative

thereof. These forward-looking statements are based

on

management’s

current

expectations

and

are

subject

to

a

number

of

risks,

uncertainties,

and

assumptions,

including

market

and

economic

conditions,

business

prospects

or

opportunities,

future

plans

and

strategies,

projections

and

anticipated events

and trends

that affect

the Company

and its

industry.

Although management

of the

Company believes

that

the

expectations

reflected

in

such

forward-looking

statements

are

reasonable

and

are

based

on

reasonable

assumptions

and

estimates

as

of

the

date

hereof,

there

can

be

no

assurance

that

these

assumptions

or

estimates

are

accurate or that any of these expectations will prove accurate.

Actual

results

and

developments

are

likely

to

differ,

and

may

differ

materially,

from

those

anticipated

by

the

Company and expressed or implied by

the forward-looking statements contained in this AIF. Such statements are based on

a number of assumptions and risks which may prove to be incorrect.

Important assumptions relating to the forward-looking

statements contained in this AIF include, among other things,

assumptions concerning:

the Company’s business strategies, strategic objectives

and growth strategy;

the Company’s expected production volumes, rates

and costs;

the Company’s current and future capital resources

and the need for additional financing;

the Company’s ability to increase sales from new and existing customers, and the results of the successful

completion of the Company’s current projects;

management’s expectation that the Company will achieve

growth and profitability;

Table

the Company’s overall financial performance;

the Company continuing to maintain sufficient

and effective production and research and development;

there being no significant reduction in the availability of

qualified and cost-effective human resources;

there will be adequate liquidity available to the Company

to carry out its operations;

the Company’s ability to obtain and retain key

personnel; and

the success of intellectual property applications.

By their nature, forward-looking statements require assumptions and are subject to inherent risks and

uncertainties

including

those

discussed

herein.

There

is

significant

risk

that

predictions

and

other

forward-looking

statements

will

not

prove

to

be

accurate.

Readers

are

cautioned

to

not

place

undue

reliance

on

forward-looking

statements

made

herein

because a

number

of factors

could cause

actual future

results, conditions,

actions

or events

to differ

materially from

the

targets, expectations, estimates or intentions expressed in the

forward-looking statements.

The future

outcomes that

relate to

forward-looking statements

may be

influenced by

many factors,

including, but

not limited to, the risk

factors described under

the heading “Risk Factors”.

The Company cautions that

the foregoing list of

factors

is

not

exhaustive,

and

that,

when

relying

on

forward-looking

statements

to

make

decisions

with

respect

to

the

Company, investors

and others should carefully consider these factors, as well as other uncertainties and potential events,

and the inherent uncertainty of forward-looking statements.

Although the forward-looking statements

contained in this AIF

are based upon

what management currently believes

to be reasonable assumptions, the Company cannot assure investors that actual results, performance or achievements will

be

consistent

with

these

forward-looking

statements

and

additional

risks

and

uncertainties

discussed

in

the

Company’s

materials filed with the

Canadian securities regulatory

authorities from time

to time, available

under the Company’s

profile

on SEDAR at

www.sedar.com and on EDGAR at www.sec.gov. There can be no

assurance that forward-looking statements

will prove

to be

accurate, as actual

results and

future events

could differ materially

from those

anticipated in

such statements.

Accordingly,

readers

should

not

place

undue

reliance

on

forward-looking

statements.

Forward-looking

statements

are

provided

as

of

the

date

of

this

AIF,

and

the

Company

assumes

no

obligation

to

update

or

revise

such

forward-looking

statements to reflect new events or circumstances except as

required under applicable securities laws.

The

forward-looking

statements

contained

in

this

AIF

are

expressly

qualified

in

their

entirety

by

this

cautionary

statement and are made as of the date of this AIF or such

other date specified herein.

On December 16,

2020, the Company

announced it had

signed an addition

al contract with

a US-based

Corporate Developments and Financings

On March

18, 2020,

the Company

completed a

$903,000 non-brokered

secured convertible

loan with

Fiducie de

Crédit Mellon Trust (the “

Pascali Trust

”), a trust of which Company’s Chief Executive Officer, P.

Peter Pascali, is a trustee,

officer

and

beneficiary

(the

2020 Convertible

Loan

”).

The

2020

Convertible

Loan

bore

interest

at

the

rate

of

12%

per

annum, with interest

payable in cash

on a quarterly

basis, had a

September 17, 2021,

maturity date,

and was convertible

into common

shares of

the Company

at a

conversion price

of $0.28

per common

share. The

2020 Convertible

Loan was

secured

by

a

hypothec

on

the

universality

of

all

of

the

present

and

after

acquired

moveable

property

and

assets

of

the

Company.

The

2020

Convertible

Loan

was

subsequently

converted

in

common

shares

in

accordance

with

its

terms

on

September 30, 2020, resulting

in 3,225,000 common shares

being issued. As the

2020 Convertible Loan was

provided by

the Pascali Trust,

the 2020 Convertible Loan

constituted a “related party

transaction” as defined in

MI 61 101. The

related

party transaction was exempt from

the formal valuation and minority

approval requirements of MI 61-101,

as the transaction

had

a

value

of

less

than

25%

of

the

Company’s

market

capitalization

(calculated

in

accordance

with

MI

61-101).

The

transaction was unanimously

approved by the

board of directors

of the Company.

See “Directors and

Executive Officers -

Conflicts of Interest”.

On July 28,

2020, the Company

requested that

the Pascali Trust

convert the

2020 Convertible

Loan on or

before

September 30, 2020.

The Pascali Trust

agreed to such

request subject to

the prepayment of

5 years rent,

plus estimated

yearly municipal taxes, no

later than December 31,

2020, for a

total prepayment of $1,438,530.

As a result

of the conversion

of the 2020 Convertible Loan, the Company saved approximately $110,000 of interest payments that would otherwise have

been

required

to

be

paid

under

the

2020

Convertible

Loan.

The

agreement

with

the

Pascali

Trust

in

respect

of

the

prepayment

of

rent

constituted

a

“related

party

transaction”

as

defined

in

MI

61101.

The

related

party

transaction

was

exempt from the formal

valuation and minority

approval requirements of

MI 61-101, as

the transaction had

a value of less

than

25%

of

the

Company’s

market

capitalization

(calculated

in

accordance

with

MI

61-101).

The

transaction

was

unanimously

approved

by

the

board

of

directors

of

the

Company.

See

“Directors

and

Executive

Officers

-

Conflicts

of

Interest”.

On September 1,

2020, PyroGenesis announced that it

had acquired 4,000,000 units

Plasma Torches for Iron Ore Pelletization

PyroGenesis

manufactures

and

commercializes

proprietary

plasma

torches

and

plasma

torch

systems

used

to

replace fossil

fuel burners

in industrial

iron ore

pelletization process.

The Company’s

plasma torches

can heat

gas up

to

10,000°F,

which is as hot as the surface of the sun.

Pelletization is the

process in which

iron ore fines

are agglomerated into

small balls with

some additives and

then

heated

at

high

temperatures

in

an

induration

furnace

to

make

them

more

resistant.

The

resulting

pellets

downstream and typically on a different site to make iron and steel in blast furnaces

and in direct reduction of iron (DRI). In

conventional technology,

the process

heat is

provided by

fuel oil or

natural gas

burners. The

combustion of

fossil fuels

in

these burners results in the production

of GHGs, notably carbon dioxide. Because plasma

torches use renewable electricity

to generate heat, they offer an environmentally

attractive alternative to fossil fuel burners.

The objective of

the Company is

to be

a significant player

in the

world-wide movement to

reduce the carbon

footprint

in mining and

manufacturing. PyroGenesis

offers a patented

process to replace

fossil fuel burners

with electrically heated

plasma torches, thereby reducing GHG emissions for

the iron ore pelletization industry. The Company believes its solutions

can be economically attractive

with greater environment

benefits than the traditional

alternatives. By using

the Company’s

solutions, companies

can convert

their existing

burners

and systems

often without

needing to

shut down

their facility

for

installation and with minimal changes to their processes.

Waste Destruction and Waste-to-Energy

Systems

PyroGenesis manufactures and

commercializes a broad

range of waste destruction

and waste-to-energy systems

to customers in the environmental and defense industries. At the core of these systems are the Company’s plasma torches

and

plasma

gasification

reactors.

The

Company

believes

it

offers

one

of

the

most

complete,

easy-to-operate,

high

temperature,

plasma-based

treatment

systems.

The

waste

destruction

and

waste-to-energy

systems

offered

by

the

Company include the following:

Plasma Arc Waste Destruction Systems

(“

PAWDS

”) for waste destruction onboard ships;

Steam

Plasma

Arc

Refrigerant

Cracking

(“

SPARC

”)

systems

for

the

destruction

of

certain

refrigerants,

including

chlorofluorocarbons

(“

CFCs

”),

hydrofluorocarbons

(“

HFCs

”)

and

hydrochlorofluorocarbons

(“

HCFCs

”);

Plasma Arc Chemical

Warfare Agent

Destruction Systems

(“

PACWADS

”), which

are mobile platforms

for

the onsite destruction of chemical warfare agents;

Plasma

Resource

Recovery

Systems

(“

PRRS

”)

for

land-based

waste

destruction

and

waste-to-energy

applications;

Plasma torches for waste gasification and combustion; and

Plasma Arc Gasification and Vitrification (“

PAGV

”).

Plasma Arc Waste Destruction System (PAWDS)

Originally

developed

by

the

Company

in

the

late

1990s

for

the

gasification

of

waste

onboard

US

Navy

aircraft

carriers, PAWDS

was the

first plasma

destruction system

for marine

use on

US Navy

aircraft carriers.

PAWDS

uses the

plasma eductor for the fast gasification

of milled waste. Navy waste

is comparable to the combustible

fraction of municipal

solid

waste,

comprised

of

paper,

cardboard,

plastics,

wood

and

rags.

Since

launching

PAWDS

in

1999,

the

Company

received orders

for four

PAWDS

for the

US Navy,

two of

which have

been delivered

and installed

on the

Gerald R.

Ford

(CVN-78) and the

John F.

Kennedy (CVN-79) aircraft

carriers, and two

of which are

to be installed

in two planned

aircraft

carriers during

the construction

of those

vessels. Developed

in collaboration

with the

US Navy,

at 1/5th

the size

and half

the weight of a

typical marine incinerator, the patented PAWDS has a capacity of 3.5

tons/day. PAWDS

is a highly compact,

inherently safe and efficient alternative to the shipboard

waste incinerators.

Steam Plasma Arc Refrigerant Cracking (SPARC)

The SPARC

process is

the Company’s

patented technology

for the

destruction of

old refrigerants

such as

CFCs,

HFC and HCFCs. The system is pre-assembled on skids

and has demonstrated high destruction and removal efficiency

of

more

than

99.9999%.

The

SPARC

system

uses

a

water

vapour

(steam)

torch

to

destroy

the

refrigerants

quickly

and

efficiently. The system is designed to handle wastes that have very high

chlorine and fluorine content. An integrated caustic

scrubber ensures that

hydrochloric acid (HCl)

and hydrofluoric acid (HF)

emissions are well

below accepted limits. The

base

system is designed for a destruction capacity of 50 kilograms

per hour based on the refrigerant R12.

Plasma Arc Chemical Warfare Agent

Destruction System (PACWADS)

PACWADS

was developed by the Company

for the US and UK

special forces to destroy

chemical warfare agents

on site. The system

is installed on

two trailers and

can be deployed

quickly in areas

where chemical warfare

agents must

Table

of Contents

14

be immediately destroyed. Performance tests

on simulants have demonstrated destruction

and removal efficiency

of more

than 99.99999%.

The system

is designed

to destroy

the equivalent

of two

barrels (or

approximately 318

litres) per

day of

sarin, a deadly nerve gas, and is also suitable for the destruction

of a variety of other chemical warfare agents.

Plasma Resource Recovery System (PRRS)

The PRRS is used to convert waste to syngas (synthesis

gas) and inert slag (a glass-like by-product left

over after

a desired

metal

has

been

separated

(i.e.,

smelted)

from

its

raw ore).

The

PRRS

combines

a direct

current

graphite

arc

furnace, where the

inorganic portion of

waste is vitrified,

and the organic

portion is gasified.

The produced

syngas is then

cleaned up in a

plasma-fired eductor, similar to the one used

in the PAWDS technology, where tars are converted into clean

syngas (i.e. carbon monoxide and hydrogen).

The resulting syngas is further cleaned

of contaminants (such as HCl, sulfur

compounds, particulates

and volatile heavy

metals) using filters

and scrubbers.

The resulting syngas

can be used

as fuel

in a gas engine. The inert slag can be used as construction

material.

Plasma Torches

for Waste Gasification Systems

PyroGenesis’

plasma

torch

systems

are

used

in

waste-to-energy

applications,

advanced

material

production,

metallurgical

processing,

thermal

treatment

and

nanotechnology

manufacturing.

As

a

cleantech

alternative

to

fossil

fuel

burning, PyroGenesis’ electricity-driven plasma torch systems are easy to operate and offer a high level of safety, reliability

and service life of wear components.

Plasma Arc Gasification and Vitrification (PAGV)

PAGV systems convert incinerator ash and other hazardous inorganic material to

an inert, non-toxic slag. Slag is a

glass like

material, composed

of several

oxides, typically

silica

based. Using

the Company’s

unique furnace

design, the

proprietary arc plasma technology uses graphite electrodes and an electrical current to create arcs between the electrodes

and the melt, generating a high

temperature environment (typically above 1500°C) and melting the mineral matter into

slag.

This slag can be

used in a wide

range of applications, namely as

a building material for construction (e.g.

aggregate asphalt

and flooring as

well as partial

replacement for

cement in

concrete). The

PAGV

systems minimize

future legacy

issues for

operators of

incinerators (notably

municipalities

as well

as managers

of incineration

operations

for industrial,

hazardous,

biomedical, and animal

(slaughterhouse) waste) with a

relatively simple melting

process for their

grate and fly

ash. Asbestos

waste from decommissioning operations is also an excellent use

for this technology.

Systems for the Recovery of Aluminum and Other

Metal from Dross

Dross, a by-product of the

smelting process for aluminum and other metals, presents

the metallurgical industry with

challenges

and

opportunities.

A

dross

is

normally

composed

of

roughly

60%

metal

and

40%

residue.

Traditional

dross

treatment techniques

typically contaminate

the residues

with salt.

Metallurgical companies

aim to

recover metal

found in

dross while properly disposing of the oft-contaminated

residue.

PyroGenesis produces

systems for

the recovery

of aluminum

and other

metal from

dross through

its DROSRITE

process. This

process is

a salt-free,

cost-effective, sustainable

process for

maximizing metal

recovery from

dross without

any hazardous by-products. By using the DROSRITE technology, the residues can be converted into high-margin chemical

and metallurgical

products, including ammonium

sulphate and

aluminum sulphate. DROSRITE

allows the

treatment of dross

at its

source of

generation in a

controlled atmosphere,

tilting rotary furnace,

and minimizes

costly loss

of metal

while reducing

a smelter’s carbon footprint and energy consumption.

The following images compare the traditional

process for the recovery and treatment

of dross with the DROSRITE

process:

These systems are predominantly offered to customers in the metallurgical industry, targeting mainly the aluminum

and zinc industries.

Production of High Purity Spherical Metal Powders

The Company

produces

high purity

spherical

metal

powders

through

its plasma

atomization

process,

which

are

predominantly offered to customers in the additive

manufacturing (also known as 3D printing) industry.

PyroGenesis’

plasma

atomization

process

(known

as

NEXGEN

plasma

atomization)

allows

the

Company

to

produce and

sell high purity

spherical metal powders,

including titanium alloy

powders. Many existing

reactive metals cannot

easily

be

transformed

into

high

purity

spherical

powders,

especially

not

in

finer

size

cuts

such

as

-45μm/+15μm.

PyroGenesis’ NEXGEN process

offers an

improved yield

in the

finer size

cuts along

with a

higher production

rate. In

addition,

PyroGenesis can

convert a

wider variety

of metals

and alloys

into high

purity spherical

powders since

its plasma

torches

use argon gas and the reactor is backfilled with argon. This ensures the powders produced are

not exposed to any oxygen

during the

production process

and, as

a result,

PyroGenesis is

able to

produce high

purity powder

such as

titanium alloy

powders (Ti 6Al-4V grade 23).

Development of Processes to Produce High Purity

Silicon Metals, Nano Powders and Nanowires

The Company

is developing

processes

to produce

high purity

silicon metals

through

its PUREVAP

process

and

nano powders and

nanowires through

its PUREVAP

NSiR process.

These applications are

expected to be

predominantly

offered to

customers in

the mining

and metallurgical

industries, including

those involved

in the

making and/or

disposal of

batteries.

PUREVAP is a patent pending, one-step proprietary process being developed by the Company that uses a plasma

arc within

a vacuum furnace

to produce

high purity metallurgical

grade silicon and

solar grade silicon

from quartz. PUREVAP

Development of a Process to Produce Fumed Silica

From Quartz

This plasma-based process allows a direct quartz-to-fumed silica transformation, removing the

usage of hazardous

chemical in the conventional making of fumed silica

and eliminating the hydrogen chloride gas normally

associated with its

manufacturing.

Furthermore,

the

process

requires

15,000

kWh

to

produce

a

metric

ton

of

fumed

silica,

representing

a

significant reduction in the energy footprint normally associated

with manufacturing fumed silica. And because the process

uses quartz as

feedstock, it is

expected that capital

requirements to build

a plant using

this plasma-based

process will be

significantly less than the capital requirements required to

build a traditional fumed silica plant.

HPQ Polvere acquired the intellectual property

rights to the fuming silica

patent in 2021 and PyroGenesis is

entitled

to a royalty

of 10% on

the future

annual gross

sales of fumed

silica by HPQ

Polvere, subject

to the terms

of the contract.

The royalty stream can,

at any time, be

converted by PyroGenesis

Markets and Opportunities

Waste Destruction and Waste-to-Energy

Systems

Marine Waste Treatment

Market (PAWDS)

Marine waste has been

an issue for lawmakers

and corporations for decades.

The disposal of waste

overboard is

harmful

to

the

marine

environment.

National

governments

and

international

organizations

(such

as

the

International

Maritime Organization) have adopted

rules to minimize the discharge

of harmful waste and

effluents from commercial

and

non-commercial ships.

At the

same time,

onboard storage

of waste

takes up

valuable space

within the

hull of

a ship

and

the eventual disposal in port is

costly and, if not handled properly, harmful to the environment. To mitigate this, modern ship

builders have incorporated onboard marine incinerators

to treat waste. However, these incinerators

also occupy significant

space, sometimes ascending through several decks of

a ship.

Table

of Contents

17

PyroGenesis’ PAWDS

provides an innovative

solution to these

issues. The

entire system

can fit in

the headroom

of a single

deck. It

is also

capable of

being started

up or

shut down

in a matter

of minutes.

Finally,

it does

not create

the

same level of GHG and other harmful emissions associated

with traditional incinerators.

At present, the

most attractive target

market for the

PAWDS

is military navies.

PyroGenesis has and

continues to

do

business

with

the

US

Navy

and

its

contractors.

PyroGenesis

has

already

outfitted

US

Navy

aircraft

carriers

with

its

PAWDS

and will

continue

aggressively

exploring this

market. The

price of

each

PAWDS

built for

the US

Navy

currently

ranges between US$5 to 6 million and new US aircraft carriers

are built every five to seven years.

In addition to new navy vessels, PyroGenesis also sees a potential market in the retrofitting of existing ships. As of

March 2023,

the U.S.

Navy fleet

comprises approximately

240 active

in commission

ships, including

11

aircraft carriers.

1

The Company

believes some

or all

of these

existing aircraft

carriers may

be candidates

for retrofitting

their legacy

waste

management systems with a PAWDS.

Waste-to-Energy Market (PRRS)

Waste management is a large and

growing market on a global scale. The methods

of managing waste are shifting

from disposal towards recycling and

resource recovery.

Governments, industries, and society

in general are seeking more

sustainable waste management

practices that have

lower environmental impacts

than traditional solutions

such as landfill

or incineration.

Just as

responsible waste

treatment systems

are seen

as an environment

and societal

priority,

solutions that

are

capable of

transforming waste

into energy

has also

seen major

growth on

a global

scale. Recent

research identified

the

global waste to energy

market as valued in excess of

US$35 billion in 2019, with

projections that it will

exceed US$50 billion

by 2027.

2

PyroGenesis looks to continue to expand its business in this fast-growing area. The Company believes its PRRS is

already a viable and economic alternative for small capacity projects compared to conventional

incinerators.

The system is

well suited for the

decentralized treatment of industrial, hazardous, and

clinical waste. As such, in

the short to medium

term,

the

Company

is

targeting

markets

that

are

readily

accessible

for

plasma

waste-to-energy

conversion,

which

include

industrial, hazardous, non-hazardous remote communities, military bases, and

medical wastes. In the medium

to long term,

the Company also intends to target the municipal solid

waste market with larger system capacities of up to 100

tons/day.

PyroGenesis is currently engaged in pilot testing of its PRRS technology with two

Canadian clients. The aim of the

testing is to

establish the design

basis for larger

commercial systems

that will be

proposed to the

customers following

the

end of pilot

testing. PyroGenesis

is working with

one such client,

Aluminerie Alouette,

to create a

plasma solution to

treat

the

hazardous

solid

wastes

produced

by

this

industrial

client.

The

Aluminerie

Alouette

project

aims

to

not

only

produce

energy rich

syngas that

the client

will use

to reduce

its consumption

of purchased

fuels, but

also to

generate a

valuable,

safe material from the client’s waste.

End-of-Life Refrigerant Destruction (SPARC)

The

international

community

has

long

recognized

that

certain

substances

have

been

having

harmful

effects

of

ozone depleting substances (“ODS”) as well

as impacting climate change. These substances

often attack the ozone layer,

the protective shield

that covers

earth’s atmosphere

and protects its

ecologies and inhabitants

from harmful solar

UV and

UVC

radiation.

They

also

can

lead

the

emission

of

GHGs,

which

alters

the

global

climate.

Refrigerants

used

in

the

refrigeration

cycle

of air

conditioning

systems

and

heat

pumps

have

played

a significant

factor

in

both.

CFC

and HCFC

refrigerants are potent ODSs, while CFC, HCFC, and HFC

refrigerants all contribute to GHG emissions.

While emissions

from ODS

have started

to fall

and the

ozone layer

slowly heal,

there remains

an active

need for

safe

and

effective

means

of

controlling

and

disposing

of

these

harmful

refrigerants.

PyroGenesis’

SPARC

system

uses

plasma technology

to destroy

CFCs, HCFCs

and HFCs,

including from

end-of-life cooling

apparatus. These

gases must

typically be destroyed when they cannot be recycled.

PyroGenesis

continues

to

explore

potential

applications

for

the

SPARC

technology,

especially

in

markets

with

limited conventional incineration capacity.

An example is the project initiated with The Trust for the Destruction of Synthetic

Refrigerants,

a

New

Zealand

government-mandated

organization,

in

which

the

SPARC

system

will

be

used

to

destroy

refrigerants and assist New Zealand in its ambitious goals

to reduce synthetic gas emissions.

Plasma Torch Market

A plasma

torch

is a

device

for generating

a

directed

flow

of

plasma

and,

as indicated

in

numerous

parts

of

this

document,

can

be

used

in

several

applications.

PyroGenesis’

plasma

torches

are

used

in,

among

other

things,

waste

treatment systems

(waste gasification

and vitrification),

its PAWDS

and PRRS

systems,

thermal spray

(plasma spray)

in

advanced materials production, and metallurgical applications.

Plasma torches can

be effective

and relatively

safe replacements

to conventional

fuel or gas

burners in industrial

furnaces. For

example, customers

use PyroGenesis’

patented pelletizing

apparatus

to perform

the induration

of iron

ore

concentrate pellets in

a tunnel

furnace heated by

plasma torches. By

using PyroGenesis’ electricity powered

plasma torches

instead of

burning natural

gas, heavy

oil, or

pulverized

coal to

power burners,

the generation

of harmful

GHGs

(notably

carbon dioxide) is greatly reduced relative to conventional iron ore

pelletizing processes.

The Company

sees excellent

potential for growth

in the

sale of plasma

torch systems.

The global

iron ore

pellets

market alone

already exceeds

US$45 billion

and the

demand for

iron ore

pellets is

expected to

near 540,000

kilotons by

2027.

3

To date, PyroGenesis

occupies only a fraction of this market. But given the global appetite for more environmentally

sustainable and economically viable industrial solutions, the Company expects more new and existing customers to look to

refit existing burners with its plasma torch systems and

considers itself well placed to see growth in this area.

Systems for the Recovery of Aluminum and Other

Metal from Dross

Dross is a by-product of the smelting process for aluminum

and other metals. As described early in this document,

dross presents

both a challenge

and an opportunity

for those in

the metallurgical

industry.

Dross is typically

composed of

both metal

and residue

and companies

want to

recover the

valuable metal

while treating

and/or disposing

of the residue,

which is usually contaminated.

Aluminum is one of the most popular metals in

the world. Global annual production of aluminum exceeds 65 million

metric tons

and, from

that aluminum

production, nearly

5 metric tons

of dross

is generated

annually.

4

While this

presents

exciting opportunities

for PyroGenesis,

it is

important to

note that

more than

half of

all aluminium

is produced

in China,

a

market that the Company

does not do much

business in and which

is traditionally complicated

to enter (for reasons

which

include

a

relative

lack

of

intellectual

property

protection,

restricted

market

conditions,

and

a

sometimes

politicized

commercial environment).

Over the past several years,

PyroGenesis has shifted its

DROSRITE marketing strategy from

a model focused on

selling

equipment

to

one

in

which

DROSRITE

is

offered

as

a

service

via

a

tolling

agreement.

In

a

tolling

arrangement,

PyroGenesis would build, own and operate the DROSRITE system and associated equipment for the aluminum smelter on

the smelter plant location. Although tolling revenues can vary widely

depending on the sector and geographic location, this

tolling model offers PyroGenesis the opportunity to

create recurring revenues.

Because the DROSRITE technology not only

allows users to recover valuable metal

but also treat dross and

create

valuable residues, PyroGenesis has the

opportunity to become a leader

as an onsite dross processor

that delivers a zero-

landfill/reduced carbon solution.

market size

reached US$

6.36 billion

in 2022

and is

expected to

reach US$

22.60

billion by 2030.

10

At present, PyroGenesis

focuses its additive

manufacturing sales and

marketing efforts on

titanium and its

alloys.

Titanium is a

highly sought-after material

in the aeronautical, biomedical,

and high-end automotive

industry due to its

high

strength, low density, high fracture toughness, excellent corrosion resistance and superior biocompatibility. Titanium

is also

a high margin

material (in part

because of its

attributes and desirability).

PyroGenesis will consider

additional high margin

materials to maximize the potential of its NEXGEN technology.

While plasma atomized powders can be of a higher

quality than gas atomized powders, their widespread

adoption

has so far been limited

by their higher price.

In addition to PyroGenesis,

some of the key

players in the making

of additive

manufacturing powders through plasma

atomization are 6K Additive,

Tekna

Advanced Materials, and AP&C,

which is part

of GE. With its

NEXGEN technology,

PyroGenesis aims to

gain a competitive advantage

in the market by

producing high-

quality powder by

plasma atomization

at rates comparable

to gas atomization,

all while maximizing

the yield of

powder in

the preferred size range for additive manufacturing.

PyroGenesis’ additive manufacturing sales

and marketing efforts are

done on an international footing.

Through an

exclusive

Growth Strategy

As interest in the Company’s products and services

has increased and the variety of uses for its core technologies

has

expanded,

the

Company

has

evolved

its

strategy

to

concentrate

its

solution

set

under

three

categories.

These

categories represent economic drivers that are key to

global heavy industry:

Energy Transition & Emission Reduction:

fuel

switching,

utilizing

the

Company’s

electrically

powered

plasma

torches

and

biogas

upgrading

technology to help reduce fossil fuel use and greenhouse

gas emissions.

Commodity Security & Optimization:

recovery of viable metals, and optimization

of production to increase output, to

maximize raw materials and

improve availability of critical minerals.

Waste Remediation:

safe destruction of

hazardous materials, and

the recovery and

valorization of underlying

substances such

as chemicals and minerals.

Currently,

within

each

category

the

Company

offers

several

solutions

in

different

stages

leading

up

to

commercialization, including the partial list in the diagram

below:

Going forward,

the Company’s

efforts will

be focused

around helping

customers overcome

challenges within

this

spectrum. More

information

can be

found on

each of

these solutions

and the

markets in

which they

operate above

(see

“Products and Services” and “Markets and Opportunities”)

Levering off its expertise in ultra-high temperature industrial processes, the Company typically aims to introduce its

products to markets by selling to, or partnering with,

industry-leading companies. These industry leaders not

only bring the

credibility sought when introducing new

technology but also valuable insight into

the market and potential

customers as well

as important market

feedback. This corporate

strategy of

leveraging off

these strategic partnerships

seeks growth

geared

at (i) broadening the customer base and (ii)

increasing sales to existing customers. Each of the Company’s existing product

lines has been, or

is in the process

of being, vetted or

adopted by industry

leaders. The Company

also seeks eco-friendly

business, primarily targeting offerings that reduce GHGs as opposed

to those who do not. As

part of its growth strategy, the

Company

will

also

selectively

consider

opportunities

to

broaden

and

enhance

its

product

and

market

scope

through

acquisitions.

Intellectual Property and Research and Development

The intellectual property and proprietary rights of

PyroGenesis as well as its research and development

efforts are

important

to

its

business.

Considering

the

time

and

investment

required

to

develop

new

products

and

obtain

marketing

authorization,

the

Company

places

considerable

importance

on

protecting

its

research

findings,

trade

secrets

and

technologies.

Intellectual Property

In

efforts

to

secure,

maintain,

and

protect

its

intellectual

property,

proprietary

rights

and

exclusive

technology,

PyroGenesis

relies

on

a

combination

of

patents,

trademarks,

trade

secrets,

and

other

rights

as

well

as

licenses,

non-

disclosure agreements, and various other contractual arrangements. Nothing, however,

can guarantee that the Company’s

protective measures are sufficient to prevent illicit or wrongful appropriation or misuse of its technology or the development

of the same or similar technology by a third part

Research & Development

The

Company’s

competitive

strategy

includes

a

strong

innovation

culture

and

a

long-standing

commitment

to

performing research and development.

The Company’s research

areas, including but

Table

not limited

to, the

production

of metallic

powders and

the development

of plasma

torches, are

performed and

conducted

internally out of its Montréal facility.

As

of

February

27,

2023,

the

Company

employed

twelve

engineers,

scientists

and

technicians

who

are

fully

dedicated to research and development projects. Separately, the Engineering and Process Startup and Optimization teams

are also involved

in research

and development

projects. Most

research and

development projects

are funded

by external

customers or government

grants and are

initiated to respond

to a specific

customer need. Follow

-on work and

equipment

sales can often result from these initial

research and development projects. Research and development projects are mainly

focused on product extension.

Internal research and

development expenses vary

widely from year to

year and depend on

Company priorities.

6.11.

Environmental Protection

The Company currently has active permits, including from the City

of Montréal, to carry out manufacturing activities

at the Wanklyn Facility and conduct research

and development and operate production systems at the

Turcot Facility.

The Company usually needs to

apply for a new permit each time

a new project involving testing occurs.

There are

no costs to these permits except the time required to

prepare the documentation for the City of Montréal. The time to

obtain

a permit is usually between two and four months.

6.12.

Foreign Operations

The Company, through its subsidiaries Air

Science Technologies Private Limited and Air Science

Italia S.r.l., carries

out operations in

India and Italy, respectively. The Company is in

the process of developing

a European operational strategy

to produce titanium metal powders

on the European continent. The

Company continues to consider expanding its

corporate

footprint in other jurisdictions, including the United States.

6.13.

Competition

PyroGenesis competes with

a substantial number

of companies in

the industries in

which it operates,

some of which

have greater technical and financial resources.

There can be no assurance that such

competitors are not already devoting

(or will not

devote in the

future) substantially

more resources

to the development

and marketing

of products

and services

that compete

with

those

of

the Company

or that

new

or existing

competitors

will

not enter

the

various

markets

in which

PyroGenesis is

active. There

can be

no assurance

that competitors

will not

develop new

and unknown

technologies with

which

the

Company

may

have

difficulty

competing.

Furthermore,

failure

to

remain

cost

competitive

may

result

in

PyroGenesis losing business to its competitors.

For

example,

the

Company

faces

competition

from

Europlasma

in

the

waste

destruction

and

waste-to-energy

systems markets, the Company faces competition from Altek, a division of Harsco Corp., in the systems for the recovery of

aluminum and

other metal

from dross

market, and

the Company

faces competition

from AP&C,

a GE

Additive company,

and Tekna,

a portfolio company

of Arendals Fossekompani

ASA, in the

production of high

purity spherical

metal powders

market.

Several companies

in the

world develop

and promote

thermal plasma

torches, most

notably Europlasma

S.A. in

France, Scanarc Plasma

Technologies

AB in Sweden,

Tetronics

Technologies

Ltd. in the

UK, Phoenix Solution

Company

in the USA, and Plazarium in Russia and Germany.

Dividends and Distributions

The Company has

not paid any

dividends, has no

policy on paying

dividends or distributions,

and has no

present

intention to pay dividends. The Company currently intends

to reinvest any earnings to fund the development

and growth of

its

business.

Any

future

payments

of

dividends

will

be

at

the

discretion

of

the

Board

and

will

depend

on

many

factors,

including, among other things, the Company’s

financial condition, current and anticipated capital

requirements, contractual

requirements, solvency tests imposed by applicable corporate

law and other factors it may deem relevant.

conflicts

of interest

to

operations

of

the

of

the

Company,

is

a

On October 9,

2019, Drosrite International, a

US-based private company owned

by Alex Pascali,

the son of

P. Peter

Pascali, entered

into the

Dross Processing

Service Agreement

with Radian

Oil &

Gas Services

Company,

an oil

and gas

services company operating in

the Middle East (the

“Dross Processing Service Agreement”). The

Dross Processing Service

Agreement

was

structured

as a

“BOOT”

agreement

(build,

own,

operate

and

transfer)

having

a

20-year

term

and

using

PyroGenesis’

DROSRITE

technology.

The Dross

Processing

Service Agreement

provides that

Drosrite

International

will

manufacture and

deliver to

Radian Oil

& Gas

DROSRITE TPY

systems which

will be

installed at

the aluminium

smelting

facility

of

Ma’aden

Aluminum

Company

located

at

Ras

Al-Khair,

in

Saudi

Arabia.

In

addition,

Drosrite

International

will

oversee the

installation of

the systems

at the

Ras Al-Khair

facility.

Drosrite International

will also

supply spare

parts over

the 20-year

duration of

the

Dross Processing

Service Agreement

and be

entitled to

receive

an annual

royalty.

The

total

value of

the

project

exceeds

US$17 million.

The amount

remaining

to be

collected

is approximately

US$9

million of

the

initial US$17 million purchase order with remaining billings of roughly US$1 million to be issued. There is also an additional

approximately

US$450,000

to

be

collected

for

transportation,

storage,

and

insurance

fees.

In connection with the Dross Processing Service Agreement between

Drosrite International and Radian Oil & Gas,

between PyroGenesis and Drosrite

International on August

29, 2019, under which Drosrite International received the required rights from PyroGenesis

to perform its obligations under

its

agreement

with

Radian

Oil

Under

the

Drosrite

International is

Alex Pascali,

an employee

of the

Company

and

the

son

of

P.

Peter

Pascali,

Chief

Executive

Officer

of

the

Company.

Drosrite

International

does

not

receive

any

management, administration or other fee from the Company.

Drosrite International is, on an accounting basis, a subsidiary

of the Company and

not a client, as

under applicable accounting standards the

Company is considered to effectively control

Drosrite

International.

The

Company

has

to

indemnify

Drosrite

International

for

any

claims

and

liabilities

incurred

in

connection with

the Drosrite

systems. The

Company’s

Drosrite technology

was protected

by patents

until 2017

and new

patent applications pertaining to the technology have been

filed before 2017, which patent applications are pending.

To the best of

the Company’s knowledge,

other than

as disclosed

in this

AIF, there are no

known existing

or potential

conflicts of interest among the Company, the directors and officers of the Company or other members of management or of

any proposed

promoter,

director,

officer

or other

member

of

management

as a

result of

their

outside

business

interests

except that

certain of the

directors and officers

serve as directors

and officers of

other companies, and

therefore it is

possible

that

a

conflict

may

arise

between

their

duties

to

the

Company

and

their

duties

as

a

director

or

officer

of

such

other

companies.

A director who has a

material interest in a matter

before the Board or any

committee on which he

or she serves is

required to disclose such interest as soon as the director becomes aware of it. In situations where a director has a material

interest

in

a

matter

to

be

considered

by

the

Board

or

any

committee

on

which

he

or

she

serves,

such

director

may

be

required to

absent himself

or herself

from the

meeting while

discussions and

voting with

respect to

the matter

are taking

place. Directors are also required

to comply with the relevant

provisions of applicable corporate

laws regarding conflicts of

interest. Under the CBCA, directors who have a

material interest in any person or entity that is a party

to a material contract

or a proposed material contract

with the Company are required under

the CBCA, subject to certain

exceptions, to disclose

that

interest

and

generally

abstain

from

voting

on

any

resolution

to

approve

such

a

contract.

In

addition,

directors

and

executive officers are required to act honestly

and in good faith with a view to the best interests of the

Company.

10.5.

Board Independence

The Board believes that sound

corporate governance practices

are essential to the effective,

efficient and prudent

operation of the Company and to the enhancement of

shareholder value.

Under National Instrument

58-101 - Disclosure

of Corporate Governance

Practices, a director

is considered to

be

independent if the director is independent

within the meaning of section 1.4

of

NI 52-110

. Pursuant to section 1.4 of NI

52-

110, an independent

director is a director who is free

from any direct or indirect relationship

which could, in the view of

the

board, be reasonably expected to interfere with a director’s independent judgment. Based on information provided by each

director concerning their background, employment

and affiliations, the Board has

determined that, of the eight directors on

the Company’s

Board, P.

Peter Pascali

and Rodayna

Kafal are

not independent

under section

1.4 of

NI 52-110

because

they are executive officers of the Company.

Risk Factors

The Company has identified below

certain significant risks relating to

the business of the

Company and the industry

in which

it operates.

The following

information

is only

a summary

of certain

risk

factors and

is qualified

in its

entirety by

reference to,

and must

be read

in conjunction

with, the

detailed information

appearing elsewhere

in this

AIF.

These risks

and uncertainties

are not the

only ones facing

the Company.

Additional risks

and uncertainties

not currently

known to the

Company, or that the Company currently considers immaterial, may also impair the operations of the Company. If any such

risks

materialize

into

actual

events

or

circumstances,

the

Company’s

assets,

liabilities,

financial

condition,

results

of

operations (including future

results of

operations), business and

business prospects, are

likely to

be materially

and adversely

affected. There is no assurance

that risk management steps

taken will avoid future loss due

to the uncertainties described

below

or

other

unforeseen

risks.

An

investment

in

the

Common

Shares

or

other

securities

of

the

Company

is

highly

speculative

and

involves

a

high

degree

of

risk.

Before

making

any

investment

decision,

prospective

investors

should

carefully consider all the information contained in this document

including, in particular,

the risk factors described below.

12.1.

Risks Related to the Company’s Business

and Industry

Operating Income (Loss) and Negative Operating Cash

Flow

The Company

has a

history

of

losses

and

negative

cash

flows.

The

Company’s

operations

have

not

generated

sufficient

earnings

and

cash

flows

to

date

to

result

in

consistent

profitability

or

positive

cash

flows.

For

the

year

ended

December 31,

2022, the

Company had

net losses

of $32,167.027,

cash flows

used in operations

of $11,128,885,

and an

accumulated deficit

of $93,384,858.

To

the extent

that the

Company has

net losses

and negative

operating cash

flows in

future periods, it may

need to allocate

a portion of its

cash reserves to

fund such negative

cash flows. The

Company may

also be required

to raise additional

funds through the

issuance of equity

or debt securities,

or otherwise. There

can be no

assurance that the Company will be able to generate positive cash flows from its operations, that additional capital or other

types of financing will be available when needed or that

these financings will be on terms favourable to the Company.

The Company’s ability to continue as a going

concern is dependent upon its ability in

the future to grow its revenue,

achieve

profitable

operations,

successfully

develop

and

introduce

new

products

and,

in

the

meantime,

to

obtain

the

necessary financing

to meet

its obligations

and repay

its liabilities

when they

become due.

While the

Company has

been

successful

in

securing

financing

in

the

past,

raising

additional

funds

is

dependent

on

a

number

of

factors

outside

the

Company’s control, and as such there is no assurance that it will be able to do so in the future. If the Company

is unable to

obtain sufficient additional financing,

it may have to curtail operations

and development activities, any of which

could harm

the business,

financial

condition and

results of

operations. In

addition, the

Company may

not generate

significant

gains,

and may suffer losses, from the value of its strategic

investments in the future.

Actual Financial Position and Results of Operations May Differ Materially from

the Expectations of the Company’s

Management

The

Company’s

actual

financial

position

and

results

of

operations

may

differ

materially

from

management’s

expectations. The

Company has

from time to

time experienced

changes in

its operating

plans and delays

in the timing

of

its plans. As

a result, the Company’s revenue,

net income and cash

flow may differ materially from

the Company’s projected

revenue, net income and cash flow. The process for estimating the Company’s revenue, net income and cash flow requires

the use of judgment in determining the appropriate assumptions

and estimates. These estimates and assumptions may be

Table

of Contents

35

revised as additional information becomes available

and as additional analyses are

performed. In addition, the assumptions

used in planning may not prove to be accurate, and other factors may affect the Company’s financial condition

or results of

operations.

Revenue Risks

PyroGenesis

may

experience

delays

in

achieving

revenues,

particularly

with

plasma

gasification

projects

which

have a long

sales cycle. Revenues

may be delayed

or negatively

impacted by issues

encountered by the

Company or its

clients including:

unforeseen engineering and/or environmental problems;

delays or inability to obtain required financing, licenses, permits

and/or regulatory approvals;

supply interruptions and/or labour disputes;

foreign exchange fluctuations and/or collection risk; and

competition from other suppliers and/or alternative energy

solutions that are less capital intensive.

There is no assurance that the business of the

Company will perform as expected or that returns from the

business

will support the expenditures needed to develop it.

Concentration Risk

To

date, a

small number

of customers

have accounted

for a

majority of

PyroGenesis’ revenues.

As its

business

expands, the Company

expects that revenue

distribution will be

over a larger

number of different

customers. For

the year

ended December 31, 2022, sales

of PyroGenesis to its

two principal customers accounted for approximately

52% of its total

revenue. For

the year

ended December

31, 2021,

sales to

two principal

customers

accounted for

approximately 79%

of

PyroGenesis’

total

revenue.

The

loss

of,

or

a

reduction

in,

purchase

orders

or

anticipated

purchase

orders

from

PyroGenesis’ principal

customers could

have a

material adverse

effect

on its

business, financial

condition and

results of

operations.

Additionally,

if

one

of

PyroGenesis’

customers

is

unable

to

meet

its

commitments

to

PyroGenesis,

the

Company’s business, financial condition and results

of operations could be adversely affected.

As

a

result

of

the

Drosrite

International

Exclusive

Agreement

and

the

Dross

Processing

Service

Agreement,

significant

revenues

may

be

generated

by the

Company

from payments

made to

Drosrite

International

under

the Dross

Processing

Service

Agreement.

The

Company

will

no

longer

receive

payments

under

such

arrangement

if

the

Dross

Processing

Service

Agreement,

which

involves

a

third

party

in

a

foreign

jurisdiction,

is

terminated,

which

could

have

a

material adverse effect on the business, financial

condition and results of operations of the Company.

Technology Development and Manufacturing

Capability Risks

PyroGenesis recently expanded into new

areas of business and, as a result,

many of the Company’s products

are

at various

stages of

the development

cycle. The

Company may

be unable

to commercialize

such products,

or it

may be

unable

to

manufacture

such

products

in

a

commercially

viable

manner.

Whilst

management

is

confident

in

both

the

Company’s technology and in

its team of

experienced engineers, scientists and

technicians, management cannot know with

certainty

which

of

the

Company’s

products

will

be

commercialized,

when

any

such

products

will

be

commercialized,

or

whether any such products will be manufactured and distributed

profitably.

Additional financing and dilution

PyroGenesis may require additional financing. There

can be no assurance

that additional financing will be

available

to the Company when needed, or on terms acceptable to the Company.

PyroGenesis’ inability to raise financing to support

ongoing operations or

to fund capital

expenditures could limit

the Company’s growth and

may have a

material adverse effect

upon the Company.

The Company

does not

exclude raising

additional funds

by equity

financing. In

addition,

as of

the date

of this

AIF,

9,815,500 stock

options and 6,014,600

warrants are

currently issued

and outstanding.

The exercise

of stock

options

and/or warrants, as well as any new equity financings,

represents dilution factors for present and future shareholders.

Table

Reliance on Third Party Suppliers, Service Providers

,

Distributors and Manufacturers

The Company’s

direct and

indirect suppliers,

service providers,

distributors and

manufacturers

may elect,

at any

time,

to

breach

or

otherwise

cease

to

participate

in

supply,

service,

distribution

or

manufacturing

agreements,

or

other

relationships,

on

which

the

Company’s

operations

rely.

Loss

of

its

suppliers,

service

providers,

distributors

and

manufacturers

could

have

a

material

adverse

effect

on

the

Company’s

business

and

operational

results.

Further,

any

disruption

in

the

manufacturing

process

done

by

third

party

manufacturers

could

have

a

material

adverse

effect

on

the

business,

financial

condition

and

results

of

operations

of

the

Company.

The

Company

cannot

ensure

that

alternative

production capacity would

be available in

the event

of a disruption,

or if it

would be available,

that it could

be obtained on

favorable terms.

Manufacturing Facilities

The

vast

majority

of

the

Company’s

products

are

manufactured

in

its

two

manufacturing

facilities

located

in

Montréal,

Québec.

Accordingly,

the

Company

is

highly

dependent

on

the

uninterrupted

and

efficient

operation

of

its

manufacturing facility.

If for

any reason

the Company

is required

to discontinue

production at

its facility,

it could

result in

significant delays in

production of the

Company’s products

and interruption of

the Company’s

sales as it

seeks to resume

production. The

Company

may be

unable to

resume production

on a

timely basis.

If operations

at the

facility

were to

be

disrupted

as

a

result

of

equipment

failures,

natural

disasters,

fires,

accidents,

work

stoppages,

power

outages

or

other

reasons, the Company’s business, financial condition

and/or results of operations could be materially adversely

affected.

Sales Cycle and Fixed Price Contracts

PyroGenesis sales cycle is long and the signing of

new contracts is subject to delay,

over which the Company has

little control. The Company also enters

into sales contracts with fixed pricing,

which may be impacted by changes

over the

period of implementation. There is no assurance that delays or problems in fulfilling contracts with clients will not adversely

affect the Company’s activities, operating

results or financial position.

Reliance on Technology

PyroGenesis

depends

upon

continuous

improvements

in

technology

to

meet

client

demands

with

respect

to

performance and cost, and to explore additional

business opportunities. There can be no assurance

that the Company will

be successful in its

efforts in this regard or

that it will have

the resources available to

meet this demand. Whilst

management

anticipates that

its research

and development

efforts will

allow the

Company to

explore additional

business opportunities,

there

is

no

guarantee

that

such

business

opportunities

will

be

presented

or

realized.

The

commercial

advantage

of

the

Company will depend to a significant extent on the intellectual property and proprietary

technology of PyroGenesis and the

ability

of

the

Company

to

prevent

others

from

copying

such

proprietary

technologies.

PyroGenesis

currently

relies

on

intellectual property rights and

other contractual or proprietary

rights, including (without limitation)

copyright, trade secrets,

confidential

procedures,

contractual

provisions,

licenses

and

patents,

to

protect

its

proprietary

technology.

PyroGenesis

may have to engage in

litigation in order to protect

its patents or other

intellectual property rights, or to

determine the validity

or

scope

of

the

proprietary

rights

of

others.

This

type

of

litigation

can

be

expensive

and

time

consuming,

regardless

of

whether or

not the

Company is successful.

PyroGenesis may seek

patents or

other similar

protections in

respect of

particular

technology; however, there can be no assurance that any future patent applications

will actually result in issued patents, or

that,

even

if

patents

are

issued,

they

will

be

of

sufficient

scope

or

strength

to

provide

meaningful

protection

or

any

commercial

advantage

to

the

Company.

Moreover,

the

process

of

seeking

patent

protection

can

itself

be

long

and

expensive. In the meantime, competitors may develop technologies that are similar or superior to PyroGenesis’ technology

or design around the patents owned by the Company, thereby adversely affecting the Company’s competitive advantage in

one or more of its areas of business. Despite the efforts

of the Company, its intellectual

property rights may be invalidated,

circumvented, challenged, infringed or

required to be licensed to others.

It cannot be assured that

any steps the Company

may take

to protect

its intellectual

property rights

and other

rights to

such proprietary

technologies that

are central

to the

Company’s operations will prevent misappropriation

or infringement of its technology.

Changes to Contracts

PyroGenesis

is

dependent

upon

its

ability

to

establish

and

develop

new

relationships

and

to

build

on

existing

relationships

with

current

clients.

The

Company

cannot

provide

assurance

that

it

will

be

successful

in

maintaining

or

advancing

its

relationships

with

current

clients

or

procure

additional

clients.

In

addition,

PyroGenesis

cannot

provide

assurance that its customers and the

end users of its products will

continue to provide the Company

with business, or that

existing customers

and end

users will

not seek

to renegotiate

or terminate

existing contracts

providing for

the sale

of the

Company’s products and

technology based on

circumstances on which

the Company is

not currently

aware. Any termination

Table

of Contents

37

or amendment of

a contract under

which the Company

derives an important

portion of its

revenues, including

the Drosrite

International

Exclusive

Agreement

and

the

Dross

Processing

Service

Agreement,

and

any

adverse

change

in

the

relationship

of the

Company

with its

customers

and end

users, will

have an

adverse

effect

on the

Company’s

business,

financial condition and results of operations.

Sales to governments and governmental

entities are subject to specific

additional risks, such as delays

in funding,

termination of

contracts

or sub-contracts

at the

convenience

of the

government,

termination, reduction

or modification

of

contracts or sub-contracts in

the event of changes

in the government’s policies

or as a result of budgetary

constraints and

increased or unexpected costs resulting in losses or reduced

profits under fixed price contracts.

Foreign Exchange Exposure

PyroGenesis’ products

and services

are increasingly

being sold

in markets

outside of

Canada, whilst

most of

its

operating expenses

and capital

expenditures are

denominated in

Canadian dollars.

As a result,

the Company

is exposed

to

fluctuations

in

the

foreign

exchange

rates

between

Canadian

dollar

and

the

currency

in

which

a

particular

sale

is

transacted,

which

may

result

in

foreign

exchange

losses

that

could

affect

earnings.

Foreign

sales

are

predominantly

denominated in U.S. dollars. The Company has not to date sought to hedge the risks associated with fluctuations in

foreign

exchange rates.

Competition

The industry in which the Company

operates is competitive and PyroGenesis

competes with a substantial number

of companies which have

greater technical and

financial resources. There can

be no assurance that

such competitors will

not substantially increase the resources devoted to the development

and marketing of products and services

that compete

with those of

the Company

or that new

or existing

competitors will

not enter

the various

markets in which

PyroGenesis is

active. There

can be

no assurance

that competitors

will not

develop new

and unknown

technologies with which

the Company

may have difficulty

competing. Furthermore,

failure to

remain cost competitive

may result in

PyroGenesis losing

business

to its competitors.

The plasma

technology

of

PyroGenesis

competes

against

other

plasma

and

conventional

technologies.

Without

limitation,

the

demand

for

the

plasma

technology

of

PyroGenesis,

particularly

in

waste

destruction

and

waste-to-energy

systems, can be impacted by the commodity prices of the energy source used for the process and the price at which waste

is accepted by

landfills and

traditional waste

processing plants.

While the Company

believes that

demand for sustainable

waste management practices

that have

lower environmental impacts

than traditional solutions

such as landfill

or incineration

is

increasing,

the

high

flows

of

electricity

necessary

to

operate

the

waste

destruction

and

waste-to-energy

systems

of

PyroGenesis have an

impact on the

operational costs

of the Company’s

systems, and traditional

solutions may

constitute

lower-cost solutions, particularly if commodity prices (including

of oil and natural gas) are low or experience a decline.

Management and Key Personnel

PyroGenesis

depends

on

the

skills

and

experience

of

its

executive

and

management

team

and

other

key

employees.

The

Company

relies

heavily

on

its

ability

to

attract

and

retain

highly

skilled

personnel

in

a

competitive

environment. PyroGenesis may be

unable to recruit, retain, and

motivate highly skilled executives

and employees in order

to assist the Company’s

business, especially activities

that are essential to

the success of

the Company.

Failure to recruit

and retain

highly skilled

executives

and

employees

may adversely

affect

PyroGenesis’

business, financial

condition

and

results of operations.

Implementation of a Strategic Plan

PyroGenesis’ commercial strategy aims to leverage its products, consumables, and services whilst focusing on the

resolution of problems

within niche markets within

the industries served by

the Company.

There can be no

assurances as

to the

success

of the

Company’s

strategic

plan,

which

should

be considered

under

the risks

perspective

and

difficulties

frequently encountered by a developing business.

Adverse Decisions of Sovereign Governments

PyroGenesis

conducts

an

increasing

portion

of

its

business

internationally.

There

is

no

assurance

that

any

sovereign government, including Canada’s, will not establish laws or regulations that may be detrimental to the Company’s

interests or

that PyroGenesis

will continue

to have

access to

the regulatory

agencies in

the countries

in which

it sells

or

seeks

to

sell,

directly

or

indirectly,

its

products

and

services.

Governments

have,

from

time

to

time,

established

foreign

Table

38

exchange controls, which could

have a material adverse effect

on the Company’s business,

financial condition and results

of operations.

Risks Related to International Operations

A substantial

portion of the

Company’s sales

are made to

customers and

end users

outside Canada,

including in

the United States, the European Union and

the Middle East. The Company conducts

its international operations directly or

through distributors

or other

agents or

intermediaries, including

Drosrite International.

The Company

plans to

continue to

expand its international sales and marketing

efforts. International operations are subject

to a number of inherent risks, and

the Company’s future results could be adversely affected

by a number of factors, including:

unfavorable political or economic environments;

requirements

or

preferences

for

domestic

products

or

solutions,

which

could

reduce

demand

for

the

Company’s products;

differing existing or future regulatory and certification

requirements;

unexpected legal or regulatory changes;

greater difficulty in collecting accounts receivable

and longer collection periods;

difficulties in enforcing contracts;

any inability to effectively protect intellectual property;

tariffs

and

trade

barriers,

export

regulations

and

other

regulatory

and

contractual

limitations

on

the

Company’s ability to sell its products; and

potentially adverse tax consequences, including multiple and

possibly overlapping tax structures.

Fluctuations

in currency

exchange rates

could materially

adversely

affect

sales denominated

in currencies

other

than the Canadian dollar

and cause a reduction

in revenues derived from

sales in a particular country.

Financial instability

in

foreign

markets

could

also

affect

the

sale

of

the

Company’s

products

in

international

jurisdictions.

In

addition,

the

Company may be denied

access to its end

customers as a result

of a closing of

the borders of the

countries in which it

its

products are sold due to economic, legislative, political, military

and other conditions in such countries.

There can be

no assurance

that such factors

will not materially

adversely affect

the operations,

growth prospects

and sales of

the Company

and, consequently,

its results

of operations. In

addition, revenues

the Company earns

in other

jurisdictions may be

subject to taxation by

more than one

jurisdiction, which could materially

adversely affect the Company’s

earnings. Each of these factors could have an adverse effect on the Company’s business, financial condition and results of

operations.

Governmental Regulation

PyroGenesis is subject to a variety of federal, provincial, state, local and international laws and regulations relating

namely to

the environment,

health and

safety,

export controls,

currency exchange,

labour and

employment and

taxation.

These laws and regulations

are complex, change frequently

and have tended to become

more stringent over time. Failure

to comply with these

laws and regulations may

result in a variety

of administrative, civil and

criminal enforcement measures,

including assessment

of monetary

penalties, imposition

of remedial

requirements and

issuance of

injunctions as

to future

compliance. The Company

may be subject to

compliance audits by regulatory

authorities in the various countries

in which

it operates.

Government-funded Defense and Security Programs

Like most

companies that

supply products

and services

to governments,

the Company

is subject

to routine

audit

and investigation procedures

of government agencies.

These agencies may

review the Company’s

performance under its

contracts,

business

processes,

cost

structure,

and

compliance

with

applicable

laws,

regulations

and

standards.

The

Company’s incurred costs for

each year are

subject to audit

by government agencies, which

can result in

payment demands

related to costs

they believe

should be

disallowed. The

Company works

with governments

to assess

the merits

of claims

and

where

appropriate

reserve

for

amounts

disputed.

The

Company

could

be

required

to

provide

repayments

to

Table

of Contents

39

governments, which may have a negative effect on its results of operations. Contrary to cost-reimbursable contracts, some

costs may not

be reimbursed or

allowed under fixed-price

contracts, which may

have a negative

effect on the

Company’s

results of operations if it experiences costs overruns.

Environmental Liability

PyroGenesis

is

subject

to

various

environmental

laws

and

regulations

enacted

in

the

jurisdictions

in

which

it

operates,

which

govern

the

manufacturing,

processing,

importation,

transportation,

handling

and

disposal

of

certain

materials used

in the

Company’s

operations. Management

believes that

it has

adequate procedures

in place

to address

compliance with current environmental laws and regulations. Furthermore, management monitors the Company’s practices

concerning the handling of environmentally hazardous materials. However,

there can be no assurance that the Company’s

procedures

will

prevent

environmental

damage

occurring

from

spills

of

materials

handled

by

the

Company

or

that

such

damage has not

already occurred.

On occasion, substantial

liabilities to third

parties may be

incurred. The Company

may

have

the

benefit

of

insurance

maintained

by

it

or

the

operator,

however

the

Company

may

become

liable

for

damages

against which it cannot adequately

insure or against which it

may elect not to

insure because of high costs

or other reasons.

The Company’s

clients are

subject to similar

environmental laws

and regulations,

as well as

limits on emissions

to the air

and discharges

into surface

and sub-surface

waters. While

regulatory developments

that may

follow in subsequent

years

could have

the effect

of reducing

industry activity,

the Company

cannot predict

the nature

of the

restrictions that

may be

imposed. The

Company may

be required

to increase

operating expenses

or capital

expenditures in

order to

comply with

any new restrictions or regulations.

Product Liability and Other Lawsuits

PyroGenesis is

subject to

a variety

of potential

product liabilities claims

and other

lawsuits related with

its operations,

including

liabilities

and

expenses

associated

with

product

defects.

The

Company

maintains

product

liability

and

other

insurance coverage that management believes is generally

in accordance with the market practice in its industry,

but there

can be no assurance that the Company will always be

adequately insured against all potential liabilities.

A

malfunction

or

the

inadequate

design

of

the

Company’s

products

could

result

in

product

liability

or

other

tort

claims.

Accidents

involving

the

Company’s

products

could

lead

to

personal

injury

or

physical

damage.

Any

liability

for

damages resulting

from malfunctions

could be

substantial and

could materially

adversely affect

the Company’s

business

and

results

of

operations.

In

addition,

a

well-publicized

actual

or

perceived

problem

could

adversely

affect

the

market’s

perception of the Company’s products and affect

its reputation. This could result in a decline in demand for the

Company’s

products, which would materially adversely affect

the Company’s financial condition and results

of operations.

The sale

and use

of products

and processes

developed or

sold by

the Company

may entail

potential liability

and

possible

warranty

claims.

The Company

is also

required

to

indemnify

Drosrite

International

for any

claims

and

liabilities

incurred in

connection with the

Drosrite systems. The

Company may be

subject to personal

injury claims for

injuries resulting

from use of its products. Although the

Company maintains product liability insurance,

there can be no assurance that such

insurance will

continue to

be available

on commercially

reasonable terms

or that

the risks

covered or

coverage amounts

will be sufficient to cover all claims.

Information Systems Disruptions

The Company

relies

on various

information

technology

systems

to manage

its operations.

Over

the last

several

years,

the

Company

has

implemented,

and

it

continues

to

implement,

modifications

and

upgrades

to

such

systems,

including changes

to legacy

systems, replacing

legacy systems

with successor

systems with

new functionality, and acquiring

new systems with

new functionality.

These types

of activities subject

the Company

to inherent costs

and risks

associated

with replacing and

changing these systems,

including impairment of

the Company’s ability

to fulfill

customer orders, potential

disruption of

its internal

control structure, substantial

capital expenditures, additional

administration and operating

expenses,

retention of

sufficiently skilled

personnel to

implement and

operate the

new systems,

demands on management

time and

other

risks

and

costs

of

delays

or

difficulties

in

transitioning

to

or

integrating

new

systems

into

the

Company’s

current

systems. These

implementations, modifications,

and upgrades

may not result

in productivity

improvements at

a level that

outweighs the costs of implementation, or at all. In addition, the difficulties with implementing new technology systems may

cause

disruptions

in

the

Company’s

business

operations

and

have

a

material

adverse

effect

on

its

business,

financial

condition, or results of operations.

Security Breaches

As part

of its

day-to-day business,

the Company

stores its

data and

certain data

about its customers

in its global

information technology system.

Unauthorized access to

the Company’s data,

including any regarding

its customers, could

expose the Company to a risk of

loss of this information, loss of

business, litigation and possible liability. Security measures

may

be

breached

by

intentional

misconduct

by

computer

hackers,

as

a

result

of

third-party

action,

employee

errors,

malfeasance

or

otherwise.

Additionally,

third

parties

may

attempt

to

fraudulently

induce

employees

or

customers

into

disclosing sensitive information

such as usernames,

passwords or other

information in order

to gain access

to the data

of

the

Company’s

customers

or

the

Company’s

data,

including

the

Company’s

intellectual

property

and

other

confidential

business

information,

or

the

Company’s

information

technology

systems.

Because

the

techniques

used

to

obtain

unauthorized access, or to sabotage systems, change frequently and generally are not recognized until launched against a

target, the Company may

be unable to anticipate

these techniques or

to implement adequate preventative

measures. Any

security breach could

result in a

loss of

confidence by the

Company’s customers, damage its

reputation, disrupt its

business,

lead to legal liability and negatively impact its future sales,

business, operations and financial results.

Public Health Crises

Public

health

crises,

including

local,

regional,

national

or

international

outbreak

of

a

contagious

disease,

could

have

an

adverse effect on

local economies, the

global economy,

and the markets

in which the

Company operates

and markets its

products, and may

adversely impact the

price and demand

for the Company’s

products and the

ability of the

Company to

operate and market

its products. Any

such alterations or

modifications could cause

substantial interruption to

the Company’s

business, any

of which

could have

a material

adverse effect

on the

Company’s operations

or financial

results, and

could

include temporary closures of

one or more

of the Company’s or

its partner’s offices or

facilities; temporary or long-term

labor

shortages; temporary or long-term adverse impacts on the Company’s supply chain and distribution channels; the potential

of increased network vulnerability and

risk of data loss resulting

from increased use of remote

access and removal of data

from the Company’s facilities.

2020

and

2021

saw

The

global

outbreak

of

COVID-19

have

devasting

effects

on

populations

and

led

to

governments

worldwide enacting emergency

measures to protect

against the spread of

the virus. In 2022,

the detrimental effects

of the

COVID-19 pandemic

on economies

and businesses

lessened with

the lifting

of most

public health

restrictions

during the

year. Like most businesses, PyroGenesis was affected

by the pandemic. However, the Company took measures to protect

its

employees

and

the

company

in

general

and

continued

its

operations

throughout

the

pandemic.

Notwithstanding

the

foregoing, there

is no

guarantee that

the global

effects of the

pandemic will

continue to improve

and if

new strains, outbreaks,

or other adverse

effects arise,

the Company and

its vendors and

suppliers may

be unable to

continue operations

or keep

up with increasing

demands as

a result

of COVID-19

and customers

may experience

delays or interruptions

in service

or

the delivery

of products, which

may be detrimental

to the

Company’s reputation, business, results

of operations and

financial

position.

The

Company

cautions

that

it

is

impossible

to

fully

anticipate

or

quantify

the

effect

and

ultimate

impact

of

the

COVID-19 pandemic as the situation still continues to evolve.

Litigation

The Company may from time

to time become party

to litigation, including in the

ordinary course of business

which

could adversely

affect its

business. Should

any litigation

in which

the Company

becomes involved

be determined

against

the Company,

such a decision could

adversely affect the

Company’s ability to

continue operating and

the market price for

the Common Shares

and could use

significant resources.

Even if the

Company is

involved in litigation

and wins, litigation

can redirect significant Company resources. Litigation may also create a negative perception of the Company’s

brand. See

“Legal Proceedings”.

Trade Secrets May Be Difficult to Protect

The

Company’s

success

depends

upon

the

skills,

knowledge

and

experience

of

its

scientific

and

technical

personnel,

consultants

and

advisors,

as

well

as

contractors.

Because

the

Company

operates

in

a

highly

competitive

industry,

it

relies

in

part

on

trade

secrets

to

protect

its

proprietary

products

and

processes.

However,

trade

secrets

are

difficult

to

protect.

The

Company

generally

enters

into

confidentiality

or

non-disclosure

agreements

with

its

corporate

partners,

employees,

consultants,

outside

scientific

collaborators,

developers

and

other

advisors.

These

agreements

generally

require

that

the

receiving

party

keep

confidential,

and

not

disclose

to

third

parties,

confidential

information

developed by the receiving

party or made known to

the receiving party by

the Company during the course

of the receiving

party’s relationship with the Company. These agreements also generally provide that inventions conceived by the receiving

party

in

the

course

of

rendering

services

to

the

Company

will

be

its

exclusive

property,

and

the

Company

enters

into

assignment agreements to perfect its rights.

Table

of Contents

41

These

confidentiality,

inventions

and

assignment

agreements,

where

in

place,

may

be

breached

and

may

not

effectively

assign intellectual

property rights

to the

Company.

The Company’s

trade secrets

also could

be independently

discovered by

competitors, in

which case

the Company

would not

be able

to prevent

the use

of such

trade secrets

by its

competitors. The enforcement of a claim alleging that a party illegally obtained and was using the Company’s trade secrets

could be difficult, expensive and time consuming and the outcome could be unpredictable. The failure to obtain or maintain

meaningful trade secret protection could adversely affect

the Company’s competitive position.

Risks Related to Acquiring Companies

The Company

has in

the past

and may

in the

future acquire

other companies

and there

are risks

inherent in

any

such acquisition.

Specifically,

there could

be unknown

or undisclosed

risks or

liabilities of

such companies

for which

the

Company is not sufficiently indemnified. Any such unknown or undisclosed risks or liabilities could materially and adversely

affect the Company’s financial performance and results of

operations. The Company could encounter additional transaction

and integration

related costs

or other factors

such as

the failure to

realize all

of the

benefits from

such acquisitions.

All of

these factors could cause dilution

to the Company’s earnings per

share or decrease or

delay the anticipated accretive effect

of the acquisition and cause a decrease in the market price of the Company’s

securities. The Company may not be able to

successfully integrate and combine the operations, personnel and technology infrastructure of any such acquired company

with its existing operations.

If integration is not

managed successfully by

the Company’s

management, the Company

may

experience interruptions in its business activities, deterioration in its employee and customer relationships, increased costs

of

integration

and

harm

to

its reputation,

all

of which

could

have

a

material

adverse

effect

on

the

Company’s

business,

financial

condition

and

results

of

operations.

The

Company

may

experience

difficulties

in

combining

corporate

cultures,

maintaining

employee

morale

and

retaining

key

employees.

The

integration

of

any

such

acquired

companies

may

also

impose substantial demands on

the management. There is no

assurance that any acquisition will

be successfully integrated

in a timely manner or at all.

Global Economic Uncertainty

Demand

for

the

Company’s

products

and

services

are

influenced

by

general

economic

and

consumer

trends

beyond

the

Company’s

control.

There

can

be

no

assurance

that

the

Company’s

business

and

corresponding

financial

performance

will

not

be

adversely

affected

by

general

economic

or

consumer

trends.

In

particular,

global

economic

conditions are still tight, and if such conditions continue, recur or worsen, there can be no assurance that they will not have

a material adverse effect on the Company’s

business, financial condition and results of operations.

Furthermore, economic conditions may produce downward pressure on

stock prices and on the availability

of credit

for financial

institutions and

corporations. If

any market

disruption and

volatility continue,

the Company

might experience

reductions

in

business

activity,

increased

funding

costs

and

funding

pressures,

as applicable,

a decrease

in

the

market

price

of

the

Common

Shares,

a

decrease

in

asset

values,

additional

write-downs

and

impairment

charges

and

lower

profitability.

Inability to Renew Leases

The

Company

may

be

unable

to

renew

or

maintain

its

leases

(commercial

or

real

property)

on

commercially

acceptable

terms

or

at

all.

Any

inability

to

renew

a

lease,

or

any

renewal

of

a

lease

with

a

rental

rate

higher

than

the

prevailing rate

under the

applicable lease

prior to

expiration, may

have an

adverse impact

on the

Company’s operations,

including disruption of its operations

or an increase in its cost

of operations. In addition, in the

event of non-renewal of any

of the Company’s

leases, the Company

may be unable

to locate suitable

replacement properties

for its facilities

or it may

experience delays in relocation that could lead to a disruption in its operations. Any disruption in the Company’s operations

could have an adverse effect on its financial condition

and results of operations.

Financial Reporting and Other Public Issuer Requirements

As

a

public

company,

the

Company

is

subject

to

the

reporting

requirements

of

the

Canadian

Securities

Administrators, or the

CSA, and

the U.S. Securities

Exchange Act

of 1934, as

amended, and the

rules and regulations

of

the listing standards of the TSX

and NASDAQ and the U.S. Sarbanes-Oxley Act.

The requirements of these laws, rules and

regulations have increased and will continue

to increase the Company’s legal,

accounting, and financial compliance costs,

make some activities

more difficult,

time-consuming, and

costly,

and place significant

strain on the

Company’s personnel,

systems, and resources. The Company is continuing to

develop and refine its disclosure controls and other

procedures that

are designed to ensure that information required to

be disclosed by the Company in the reports

that it will file with the CSA

is

recorded,

processed,

summarized,

and

reported

within

the

time

periods

specified

in

CSA

rules

and

forms

and

that

Table

of Contents

42

information required

to be

disclosed in

reports under

applicable securities

laws is

accumulated and

communicated to

the

Company’s principal

executive and

financial officers.

The Company

is also

continuing to

improve its

internal control

over

financial reporting. In order to

improve the effectiveness

of its disclosure controls and

procedures and internal control over

financial reporting, the

Company has expended,

and anticipate

that it

will continue to

expend, significant

resources, including

accounting-related costs and significant management oversight.

The

Company

has

identified

certain

material

weaknesses

in

its

internal

controls,

as

more

fully

explained

in

its

management’s

discussion

and

analysis

for

the

year

ended

December

31,

2022,

under

“Disclosure

Controls

and

Procedures”. Additional weaknesses in the Company’s disclosure

controls and internal control over financial reporting may

also be discovered in the future. Any failure

to develop or maintain effective controls

or any difficulties encountered in their

implementation or improvement

could harm

the Company’s

results of operations

or cause the

Company to fail

to meet its

reporting obligations and may result in a restatement of the Company’s financial statements for prior periods. Any failure to

improve and

maintain

effective

internal

control over

financial

reporting

also could

adversely

affect

the results

of periodic

management

evaluations

and

annual

independent

registered

public

accounting

firm

attestation

reports

regarding

the

effectiveness

of

the

Company’s

internal

control

over

financial

reporting

that

the

Company

will

eventually

be

required

to

include

in

its periodic

reports

that will

be

filed

with

the

CSA.

Ineffective

disclosure

controls

and

procedures

and

internal

control over financial reporting could also cause investors to lose confidence in the Company’s reported financial and other

information, which could have

a negative effect

on the trading price

of the Common Shares.

In addition, if the

Company is

unable to continue to meet these requirements, it may not be able

to remain listed on the TSX and/or NASDAQ.

Influence of the Significant Shareholders

To

the Company’s

knowledge, no

shareholder beneficially

owns, or controls

or directs,

directly or indirectly,

more

than

10%

of

the

voting

rights

attached

to

the

Company’s

outstanding

voting

securities,

except

for

Mr.

P.

Peter

Pascali,

President and

Chief Executive

Officer of

the Company,

who holds

or controls,

directly or

indirectly,

80,925,698 Common

Shares,

representing

in

aggregate

45.32%

of

the

total

voting

rights

attached

to

the

outstanding

Common

Shares,

and

2,500,000 share

purchase warrants

and options

to acquire

an additional

4,270,000 Common

Shares (increasing

the total

number of Common

Shares held or

controlled, directly

or indirectly,

by him to

87,695,698 Common

Shares, or 47.31%

or

the Common

Shares, on

a fully

diluted basis).

In addition,

from time

to time,

the Company

may have

other shareholders

who

have

the

ability

to

exercise

significant

influence

over

matters

submitted

to

the

shareholders

of

the

Company

for

approval, whether subject to approval by a

majority of the shareholders of the

Company or subject to a class

vote or special

resolution. See “Directors and Executive Officers

  • Conflicts of Interest”.

Joint Venture/Partnership Arrangements

The Company

may participate

in joint

ventures and

partnerships

with third

parties. A

joint venture

or partnership

arrangement involves

certain additional

risks including:

(i) the possibility

that a partner

may at any

time have economic

or

business interests

or goals

that are

inconsistent with

those of

the Company

or take

actions contrary

to the instructions

or

requests of

the Company

or contrary

to the

Company’s objectives;

(ii) the

risk that

the partner

could experience

financial

difficulties or seek the protection of bankruptcy, insolvency or other laws, which could result in additional financial demands

on the Company;

and (iii) the

need to obtain

the partner’s consent

with respect to

certain major decisions.

In addition, the

sale or transfer of an interest in joint ventures and partnerships will generally

be subject to rights of first refusal or first offer

and certain other joint

venture or partnership agreements may provide

for buy-sell or similar

arrangements. Such rights may

be triggered at a time

when the Company may not desire the

sale but may be forced to

do so because it does not

then have

the financial

resources

with

which

to purchase

the other

parties’

interests. The

terms

of any

joint venture

or partnership

arrangement

may

not

allow

the

Company

to

realize

anticipated

benefits

and

may

adversely

affect

the

Company

and

its

business.

Limited Control Over the Company’s Operations

Holders of the Common Shares have limited

control over changes in the Company’s policies and operations, which

increases

the

uncertainty

and

risks

of

an

investment

in

the

Company.

The

Board

determines

major

policies,

including

policies regarding

financing, growth,

debt capitalization and

any future

dividends to

shareholders of

the Company. Generally,

the Board may amend or revise these and other policies without a vote of the holders

of the Common Shares. The Board’s

broad

discretion

in

setting

policies

and

the

limited

ability

of

holders

of

the

Common

Shares

to

exert

control

over

those

policies increases the uncertainty and risks of an investment

in the Company.

Table

43

Change in Tax Laws

New income, sales, use

or other tax laws,

statutes, rules, regulations or

ordinances could be enacted

at any time.

Further,

existing

tax

laws,

statutes,

rules,

regulations

or

ordinances

could

be

interpreted,

changed,

modified

or

applied

adversely to the

Company.

These enactments and

events could require

the Company to

pay additional tax

amounts on a

prospective or

retroactive basis,

thereby substantially

increasing the

amount of

taxes the

Company is

liable to

pay in

the

relevant tax jurisdictions.

Accordingly,

these events could

decrease the capital

that the Company

has available to

operate

its business. Any or all of these events could harm the

business and financial performance of the Company.

Forward-Looking Information

The forward-looking information

included in this AIF relating

to, among other things,

the Company’s future

results,

performance, achievements, prospects, targets, intentions or opportunities or the markets in which it operates (including, in

particular, the information contained under “Business of the Company”, and

the other statements listed in

“Forward-Looking

Statements”)

is

based

on

opinions,

assumptions

and

estimates

made

by

the

Company’s

management

in

light

of

its

experience and

perception of

historical trends,

current conditions and

expected future developments,

as well

as other

factors

that the Company believes are appropriate and reasonable in the circumstances. However, there can be no assurance that

such estimates and assumptions will

prove to be correct. The Company’s

actual results in the future may

vary significantly

from the historical and estimated results and those variations may

be material. The Company makes no representation that

its actual

results

in the

future

will be

the same,

in whole

or in

part, as

those

included in

this AIF.

See “Forward

-Looking

Statements”.

Credit Facilities

The Company’s credit facilities and

financing agreements mature on

various dates. There can

be no assurance that

such credit facilities or financing agreements will be renewed or refinanced, or if renewed or refinanced, that the renewal or

refinancing will

occur on

equally favourable

terms to

the Company.

The Company’s

ability to

continue operating

may be

adversely

affected

if

the

Company

is

not

able

to

renew

its

credit

facilities

or

arrange

refinancing,

or

if

such

renewal

or

refinancing, as the case may

be, occurs on terms

materially less favorable to the

Company than at present. The

Company’s

current credit

facilities and

financing agreements

impose covenants

and obligations

on the

Company.

There is

a risk

that

such loans may go into

default if there is a

breach in complying with such

covenants and obligations, which

could result in

the lenders realizing on their security and causing the

Company’s shareholders to lose some or all of

their investment.

12.2.

Risks Related to the Company’s

Securities

Potential Volatility of Common Share

Price

The market price of the

Common Shares could be

subject to significant fluctuations.

Some of the factors

that may

cause the market price of the Common Shares to fluctuate

include:

the

public’s

reaction

to

the

Company’s

press

releases,

announcements

and

filings

with

regulatory

authorities and those of its competitors;

fluctuations in broader stock market prices and volumes;

changes in market valuations of similar companies;

investor perception of the Company,

its prospects or the industry in general;

additions or departures of key personnel;

commencement of or involvement in litigation;

announcements

by

the

Company

or

its

competitors

of

strategic

alliances,

significant

contracts,

new

technologies, acquisitions, commercial relationships, joint

ventures or capital commitments;

variations

in

the

Company’s

quarterly

results

of

operations

or

cash

flows

or

those

of

other

comparable

companies;

revenues

and

operating

results

failing

to

meet

the

expectations

of

securities

analysts

or

investors

in

particular quarter;

Table

of Contents

44

changes in the Company’s pricing policies or the pricing

policies of its competitors;

future issuances and sales of Common Shares;

sales of Common Shares by insiders of the Company;

third party disclosure of significant short positions;

demand for and trading volume of Common Shares;

changes

in

securities

analysts’

recommendations

and

their

estimates

of

the

Company’s

financial

performance;

short-term fluctuation in

stock price caused

by changes in

general conditions in

the domestic and

worldwide

economies or financial markets; and

the other risk factors described under this heading of the AIF.

The realization of any of these risks and other factors

beyond the Company’s control could cause

the market price

of the Common Shares to decline significantly.

In addition, broad market and industry factors may harm the market price of the Common Shares. Hence, the price

of the

Common Shares

could fluctuate

based upon

factors that

have little

or nothing

to do

with the

Company,

and these

fluctuations could materially reduce the

price of the Common Shares regardless

of the Company’s operating performance.

In

the

past,

following

a

significant

decline

in

the

market

price

of

a

company’s

securities,

there

have

been

instances

of

securities class action

litigation having

been instituted

against that company.

If the Company

were involved

in any similar

litigation, it

could incur

substantial costs,

management’s

attention and

resources could

be diverted

and it

could harm

the

Company’s business, operating results and financial

condition.

In addition, the Company

may face the risk

of being delisted from

the TSX and/or NASDAQ

if decreases in the

price

of the Common Shares do not allow the Company to

meet certain conditions of the listing exchange(s).

Market Liquidity

The market price for the Common

Shares could be subject to wide

fluctuations. Factors such as the announcement

of significant

contracts,

technological

innovations,

new

commercial

products,

patents,

a change

in

regulations,

quarterly

financial results,

future sales

of Common

Shares by

the Company

or current

shareholders, and

many other

factors could

have considerable

repercussions on

the price

of the

Common Shares.

In addition,

the financial

markets may

experience

significant price

and value

fluctuations that

affect the

market prices

of equity

securities of

companies that

sometimes are

unrelated

to

the

operating

performance

of

these

companies.

Broad

market

fluctuations,

as

well

as

economic

conditions

generally may adversely affect the market price of

the Common Shares.

Dividends to Shareholders

The Company

does not

anticipate paying

cash dividends

on the

Common Shares

in the

foreseeable future.

The

Company currently intends to retain all future earnings to fund the development and growth

of its business. Any payment of

future dividends will be at

the discretion of the

directors and will depend

on, among other things, the

Company’s earnings,

financial

condition,

capital

requirements,

level

of

indebtedness,

statutory

and

contractual

restrictions

applying

to

the

payment of dividends, and other considerations that the directors

deem relevant.

Impact of Future Sales by Existing Shareholders

If the

Company’s

shareholders sell

substantial amounts

of the

Common Shares

in the

public market,

the market

price of the

Common Shares could

decrease. The perception

among investors that

these sales will

occur could also

produce

this effect.

All currently

outstanding Common

Shares other

than those subject

to lock-up

agreements, if

any,

executed by

certain

existing

shareholders

are, subject

to

applicable

securities

laws,

generally

immediately

available

for

resale

in

the

public markets.

Subject to compliance with applicable securities laws, the Company’s officers, directors and their affiliates may sell

some or all

of their Common

Shares in the

future. No

prediction can be

made as

to the effect,

if any,

such future sales

of

Common Shares will have on

the market price of

the Common Shares prevailing from

time to time. However, the future sale

of a substantial number

of Common Shares

by the Company’s

officers, directors

and their affiliates,

or the perception

that

such sales could occur, could

materially adversely affect prevailing market prices

for the Common Shares.

Additional Common Shares issuable upon

the exercise of stock options

or warrants may also be available

for sale

in

the

public

market,

which

may

also

cause

the

market

price

of

the

Common

Shares

to

fall.

Accordingly,

if

substantial

amounts of Common Shares are sold in the public market,

the market price could fall.

Working Capital and Future Issuances

The Company may issue additional Common Shares in the future which may dilute

a shareholder’s holdings in the

Company. The Articles

permit the issuance of an unlimited number of Common Shares,

and shareholders of the Company

will have no pre-emptive rights in connection

with any further issuances. The directors

of the Company have the discretion

to

determine

the

provisions

attaching

to

the

Common

Shares

and

the

price

and

the

terms

of

issue

of

further

Common

Shares.

Additional equity

financing may

be dilutive to

holders of

Common Shares.

Debt financing

may involve

restrictions

on the Company’s financing

and operating activities. Debt

financing may be

convertible into other securities

of the Company

which may result in immediate or

resulting dilution. In either case, additional financing may

not be available to the Company

on acceptable terms

or at all.

If the Company

is unable to

raise additional funds

as needed, the

scope of its

operations or

growth may

be reduced

and, as

a result,

the Company

may be

unable to

fulfil its

long-term goals.

In this

case, investors

may lose

all or part

of their

investment. Any

default under

such debt

instruments could

have a

material adverse

effect on

the Company,

its business or the results of operations.

Securities or Industry Analysts

The

trading

market

for

Common

Shares

could

be

influenced

by

the

research

and

reports

that

industry

and/or

securities analysts, or

others, may publish

about the Company, its business,

the market or

competitors. If any

of the analysts

who may

cover the

Company’s business change their

recommendation regarding the

Common Shares adversely, or

provide

more favourable

relative recommendations

about its

competitors, the

share price

would likely

decline. If

any analyst

who

may cover

the Company’s

business were

to cease

coverage or

fail to

regularly publish

reports on

the Company,

it could

lose visibility in the financial markets, which in turn could

cause the share price or trading volume to decline.

Risks Related to the Company’s

Status as a Foreign Private Issuer

Information Publicly Available to the Company’s U.S.

Shareholders

The Company

is a

foreign private

issuer under

applicable U.S.

federal securities

laws. As

a result,

the Company

does not

file the

same reports

that a

U.S. domestic

issuer would

file with

the U.S.

Securities and

Exchange Commission

(the “

SEC

”), although the Company

is required to file

with or furnish to

the SEC the continuous

disclosure documents that

the Company is required to file in

Canada under Canadian Securities Laws, in certain respects the reporting obligations are

less

detailed

and

less

frequent

than

those

of

U.S.

domestic

reporting

companies.

In

addition,

the

Company’s

officers,

directors and principal shareholders are exempt from the reporting and short-swing profit recovery provisions of Section 16

of the U.S. Exchange Act. Therefore, the

Company’s shareholders may not know on as timely a

basis when the Company’s

officers,

directors

and

principal

shareholders

purchase

or

sell

Common

Shares

as

the

reporting

periods

under

the

corresponding Canadian insider reporting requirements

are longer.

As a foreign private issuer, the Company

is exempt from the rules and regulations under the Exchange

Act related

to the furnishing and

content of proxy statements.

The Company is also

exempt from Regulation FD,

which prohibits issuers

from making selective disclosures of

material non-public information. While

the Company complies with the

corresponding

requirements

relating

to

proxy

statements

and

disclosure

of

material

non-public

information

under

Canadian

Securities

Laws, these requirements differ from

those under the Exchange Act

and Regulation FD and

shareholders should not expect

to receive the same information at the same time as such information is provided

by U.S. domestic companies. In addition,

the Company may not be required under the Exchange Act to file

annual and quarterly reports with the SEC as promptly as

U.S. domestic companies whose securities are registered

under the Exchange Act.

In addition,

as a

foreign private

issuer, the Company has

the option

to follow

certain Canadian corporate

governance

practices, except

to the

extent that

such laws

would be

contrary to

U.S. securities

laws, and

provided that

the Company

Table

of Contents

46

discloses the requirements it is not following and describe the Canadian practices it follows instead. The Company plans to

rely

on

this

exemption.

As

a

result,

the

Company’s

shareholders

may

not

have

the

same

protections

afforded

to

shareholders of U.S. domestic companies that are subject

to all U.S. corporate governance requirements.

Loss of Foreign Private Issuer Status in the Future

In order

to maintain

its status

as a

foreign private

issuer,

a majority

of the

Company's

Common Shares

must be

either

directly

or

indirectly

owned

by

non-residents

of

the

U.S.

unless

the

Company

also

satisfies

one

of

the

additional

requirements necessary

to preserve

this status.

The Company

may in

the future

lose its

foreign private

issuer status

if a

majority of the

Common Shares

are held

in the United

States and

the Company

fails to

meet the

additional requirements

necessary to avoid

loss of foreign

private issuer

status. The

regulatory and compliance

costs to the

Company under

U.S.

federal

securities

laws

as

a

U.S.

domestic

issuer

may

be

significantly

more

than

the

costs

the

Company

incurs

as

a

Canadian foreign private

issuer eligible to use

the multi-jurisdictional disclosure

system ("

MJDS

"). If the Company

is not a

foreign private

issuer,

it would

not be eligible

to use

the MJDS

or other

foreign issuer

forms and

would be

required to

file

periodic

and

current

reports

and

registration

statements

on

U.S.

domestic

issuer

forms

with

the

SEC,

which

are

more

detailed and extensive than the forms available

to a foreign private issuer.

In addition, the Company may lose the

ability to

rely upon exemptions from Nasdaq corporate governance

requirements that are available to foreign private issuers.

Inability for U.S. Investors to Enforce Certain Judgments

The Company is a corporation existing under the Canada

Business Corporations Act. A number of the Company’s

directors and officers are residents of Canada, and substantially all of the Company’s assets are located outside the United

States. As a result, it may be difficult

to effect service within the United

States upon the Company or upon its

directors and

officers.

Execution

by

United

States

courts

of

any

judgment

obtained

against

the

Company

or

any

of

the

Company’s

directors or officers

in United

States courts may

be limited to

the assets

of such companies

or such persons,

as the case

may be,

located in

the United

States. It

may also

be

difficult

for holders

of securities

who reside

in the

United

States to

realize in the United States upon judgments of courts of the United

States predicated upon civil liability and the civil liability

of the Company’s directors and executive officers

under the United States federal securities laws. The

Company has been

advised that

a judgment

of a

U.S. court

predicated solely upon

civil liability

under U.S.

federal securities

laws or

the securities

or “blue sky” laws of any

state within the United States,

would likely be enforceable

in Canada if the United

States court in

which the judgment was obtained has a basis

for jurisdiction in the matter that would be recognized

by a Canadian court for

the same purposes. However, there may be doubt

as to the enforceability in Canada

against these non-U.S. entities or their

controlling persons,

directors

and officers

who are

not residents

of the

United States,

in original

actions or

in actions

for

enforcement of judgments of courts of the United States, of liabilities predicated solely upon U.S. federal or state securities

laws.

Risks Relating to the Company’s Status as

an "Emerging Growth Company" Under U.S. Securities

Laws

The Company

is an

“emerging growth

company” as

defined in

section 3(a)

of the

Exchange Act

(as amended

by

the JOBS

Act, enacted

on April

5, 2012),

and the Company

will continue

to qualify

as an emerging

growth company

until

the earliest

to occur

of: (a)

the last

day of

the fiscal

year during

which the

Company

has total

annual gross

revenues of

US$1,070,000,000 (as

such amount

is indexed

for inflation

every five

years by

the SEC)

or more;

(b) the

last day

of the

fiscal year

of the

Company

following the

fifth anniversary

of the

date of

the first

sale of

common

equity securities

of the

Company pursuant to

an effective

registration statement

under the United

States Securities

Act of 1933,

as amended; (c)

the date

on which

the Company

has, during

the previous

three year

period, issued

more than

US$1,000,000,000 in

non-

convertible debt; and (d) the

date on which the

Company is deemed to be

a "large accelerated filer", as

defined in Rule 12b-

2 under the

Exchange Act. The

Company will qualify as

a large accelerated filer

(and would cease to

be an emerging growth

company) at

such time

when on

the last

business

day of

its second

fiscal quarter

of such

year the

aggregate worldwide

market value of its common equity held by non-affiliates

will be US$700,000,000 or more.

For

so

long

as

the

Company

remains

an

emerging

growth

company,

it

is

permitted

to

and

intends

to

rely

upon

exemptions from certain

disclosure requirements that are

applicable to other

public companies that are

not emerging growth

companies. These exemptions include

not being required to

comply with the auditor attestation

requirements of Section 404

of the

JOBS Act.

The Company

takes advantage

of some,

but not

all, of

the available

exemptions available

to emerging

growth companies.

The Company

cannot predict

whether investors

will find

the Common

Shares less

attractive because

the Company relies upon certain

of these exemptions. If some

investors find the Common Shares less

attractive as a result,

there may be a less active trading market

for the Common Shares and the Common

Share price may be more volatile. On

the other

hand, if

the Company

no longer

qualifies as

an emerging

growth company,

the Company

would be

required to

divert additional management time

and attention from the

Company's development and

other business activities and

incur

Table

of Contents

47

increased legal and financial costs to comply with the additional associated

reporting requirements, which could negatively

impact the Company's business, financial condition and

results of operations.

13.

Legal Proceedings

The Company may,

from time to

time be involved

in legal proceedings.

The Company

is not involved

in any legal

proceedings which, individually or in the aggregate, would be material to the Company’s consolidated financial condition or

results of operations, except as follows:

The Company filed

an originating

application on

August 11,

2022, petitioning

the Quebec

Superior Court to

order

P. Riopel (1993) Inc. to convey title

of the property

bearing civic address

5655 Philippe-Turcot, Montreal, Quebec, H4C

3K8.

The

property

is

the

location

of

one

of

the

Company’s

two

manufacturing

facilities.

The

petition

followed

the

Company’s

exercise of

its contractual

option to

purchase the

property for

$2,750,000. On

December 23,

2022, P.

Riopel (1993)

Inc.

filed a counterclaim in which it

sought damages in the

amount of $415,425, alleging that

the Company breached the lease

agreement between the parties.

On July 28, 2021,

an application for a

safeguard order and permanent

injunction was filed by

AirScience Systems

Inc. (“

ASSI

”) before the

Quebec Superior

Court against

Gas RNG Systems

Inc. (“

RNG Canada

”), RNG Investments

Inc.,

Glauber Equipment

Corporation, Mr.

Peter Glauber

and Mr.

Shivaji Ramalingam

(collectively,

the “Defendants”).

ASSI is

seeking

an

oppression

remedy,

alleging

the

wrongful

expulsion

of

ASSI

as

a

shareholder

and

Mr.

Gérard

Magnin

as

a

director from RNG Canada. On April 29,

2022, the Defendants filed a defence and a

counterclaim against ASSI, AirScience

Technologies

Inc.

(“

AST

”)

(now

Pyro

Green-Gas

Inc.,

a

wholly-owned

subsidiary

of

the

Company)

and

Mr.

Magnin

for

allegedly breaching their

obligations with respect

to a unanimous

shareholder agreement

governing RNG Canada

as well

as an operating agreement governing another entity, Gas RNG Systems LLC (“

RNG US

”). The Defendants, by way of their

counterclaim, seek damages in the amount of $4.9 million. PyroGenesis has maintained that AST was never a shareholder

of either RNG Canada or RNG US nor was it a party to

the disputed shareholders and operating agreements.

On October

6, 2021,

AST filed

an action

for damages

and unpaid

invoices against

RNG Canada,

RNG

US, Mr.

Shivaji Ramalingam, Mr. Peter Glauber, Mr. Paul-Louis Crouzat and Mr. Tarlok Nandhra before the Quebec Superior Court.

On February 13, 2022, a defence and

counterclaim was filed against AST and two former shareholders of

AST (Mr. Magnin

and Mr. Paul

D. Singh), seeking approximately

$712,000 in alleged compensatory

damages. The counterclaim also

seeks

a condemnation for legal fees, moral damages and punitive

damages for approximately $771,333.

On February 17,

2023, the

Company received

a motion from

the securities regulatory

authority in the

Province of

Québec,

filed

with

the

Superior

Court

of

Québec,

pursuant

to

which

the

AMF

is

asking

the

Court

to

determine

whether

certain documents previously requested

by the AMF from the

Company are subject to

solicitor-client privilege. The

motion

was filed by the

AMF in connection

with an investigation

being conducted in

the context of

applicable securities laws.

The

Company understands

the AMF

is investigating

certain actions

taken by

the President

and Chief

Executive Officer

of the

Company,

Mr.

P.

Peter

Pascali, in

connection

with

a

settlement

agreement

entered

into on

April

30, 2018,

between the

Company and Phoenix Haute Technology

Inc. (“

Phoenix

”), a company controlled by the father of Mr. P.

Peter Pascali, and

ancillary transactions.

Pursuant

to the

terms

of a

board-approved

settlement

agreement,

and

as further

disclosed

in the

annual information form of the Company for the year

ended December 31, 2020, available under the Company’s

profile on

SEDAR at www.sedar.com, under “Interest of Management and Others in Material Transactions – Settlement of Claim”,

the

Company issued $3.7 million of units

comprised of common shares and warrants to Phoenix in

2018, to settle a $5.5 million

claim

of

Phoenix

with

respect

to

the

unpaid

portion

of

the

consideration

payable

by

the

Company

to

Phoenix

for

an

acquisition of

intellectual

property

rights completed

in

2011.

To

the

Company’s

knowledge, the

investigation

of the

AMF

does not

involve any

allegations of

wrongdoing by

the Company.

The AMF

has neither

announced any

proceedings

nor

filed

any

charges.

The

Company

believes

that

no

corporate

or

securities

laws

have

been

breached

but

cannot

predict

whether any enforcement action will result from the investigation.

OVERSEEING STANDARDS

OF INTEGRITY AND BEHAVIOUR

Management

is

responsible

for

the

Company’s

standards

of

behavior.

The

Committee

assists

the

Board

in

obtaining

assurances that management is

operating the Company in

an ethical manner and

encourages management to demonstrate

a strong commitment to integrity.

The

Committee

requests

that

management

report

periodically

on

how

the

Company’s

systems,

practices

and

controls

encourage, monitor and provide assurance of compliance with

laws, regulations and standards of ethical conduct, including

the control of expenses such as perquisites, expense

accounts and out-of-pocket expenses for officers

and directors.

Table

of Contents

52

The Committee seeks the views

of the auditors about the

Company’s standards of

behavior. It discusses

with the auditors

the adequacy of the

systems and controls, and

the details of any

practices or transactions identified by

the auditors as being

in

potential

violation

of

the

legal

authorities,

as

well

as

the

details

of

any

“other

matters”

they

consider

bringing

to

the

attention

of

the

Board.

The

committee

seeks

the

views

of

auditors

on

remedies

to

curtail

inappropriate

practices

and

behaviors, as well as alternative remedies to rectify those

matters that are not in the Company’s best interest.

The Committee values financial integrity

and credibility.

It actively promotes an overall corporate

“tone” for quality financial

reporting, sound business risk practices, and ethical behavior.

OVERSEEING FINANCIAL REPORTING

Management is responsible for the Company’s financial

reporting. This includes preparation of accurate,

fair and complete

financial

reports,

the

selection

of

the

most

appropriate

accounting

principles

and

practices,

formulation

of

accounting

judgments and estimates,

and preparation of

the annual report

including its management’s

discussion and analysis

(MD&A),

budgets and other such reports.

The Committee

shall

provide

assistance

to

the

Board

in fulfilling

its financial

reporting

and control

responsibilities

to the

shareholders of the Company and to the

investment community. The Committee’s primary duties and responsibilities in this

regard are to:

(a)

oversee the accounting and financial

reporting processes of the Company

and the audit of its financial

statements

including:

i.

the integrity of the Company’s financial statements;

ii.

the compliance with legal and regulatory requirements;

and,

iii.

the independent auditor’s qualifications and independence;

(b)

serve

as

an

independent

and

objective

party

to

monitor

the

Company’s

financial

reporting

process

and

internal

control systems;

(c)

review and appraise the audit activities of the Company’s

independent auditors;

(d)

provide open

lines of

communication among

the independent

auditors, financial

and senior

management and

the

Board for financial reporting and control matters and meet periodically with management

and with the independent

auditors.

The Committee assesses the relevance and the reliability of the financial reports to ensure that they portray, in the clearest

light possible, the underlying economic circumstances and financial

performance of the Company.

The Committee promotes accuracy,

truthfulness, integrity and credibility in financial reporting.

The Committee

discusses

with management

and auditors

the inherent

fairness,

accuracy

and completeness

of financial

disclosures as

well as

the Company’s

compliance with

legal and

regulatory requirements

and may

request attestation

to

this effect from them.

The Committee reviews

the key accounting

principles and the

significant judgments

and estimates with

management and

auditors. It seeks

their views with

respect to the

appropriateness and consistency of

the accounting principles and

practices,

not just their acceptability,

and the degree of aggressiveness or conservatism in

determining estimates.

As integral

components

of its

financial

review

processes,

the Committee

reviews

the operating

and

capital

budgets,

the

borrowing plan, summaries of the corporate

plan and budgets, the annual and

quarterly financial statements, including

the

MD&A

sections,

and

any

other

financial

information

which

will

be

distributed

to

the

public

and

requiring

approval

of

the

Board.

The Committee

assesses

how

well

the

Company’s

financial

information

reporting

package

meets

the

Board’s

needs

by

reviewing its form, content and level of details.

OVERSEEING MANAGEMENT CONTROL PRACTICES

Management is responsible for

maintaining records and financial

management and control systems

that provide reasonable

assurance that assets

are safeguarded and maintained,

that Intellectual Property

(IP) is identified, protected

and secured,

that transactions

are in accordance

with regulations

and any

government directives

issued and

that financial,

human and

physical resources are managed economically and efficiently

and that operations are carried out effectively.

Management is responsible for identifying the principal

business risks facing the Company and formulating

the Company’s

risk tolerance levels and risk management policies for consideration and approval by

the Board. The Committee assists the

Board in this function, focusing on the financial risks.

The Committee holds management

accountable for the design

and functioning of the

Company’s control framework in order

to

monitor,

assess

and

mitigate

the

Company’s

business

risks

and

uncertainty,

as

well

as

legal,

environmental,

social

responsibility

and

ethical

compliance.

Periodically,

the

Committee

requests

that

management

provides

it

with

an

assessment of the effectiveness of the internal control structure and procedures, and, if warranted, with plans for improving

its effectiveness.

The Committee reviews

with the auditors

(internal, external and

special examiners

when applicable) their

assessments of

the

design

and

functioning

of

the

control

framework

and

the

systems

in

place

for

ensuring

that

the

business

risks

are

identified, monitored,

controlled and

within the

Company’s

limit of

tolerance, and

their views

on management’s

plans for

improvements.

OVERSEEING WORK OF AUDITORS

The Committee

recognizes

that the

Company’s

auditors

possess

substantial expertise

and

have significant

professional

responsibilities. It holds the auditors accountable for fulfilling

their respective responsibilities.

The Internal auditor (when established) will be accountable

to the Committee, in its capacity as a committee

of the Board.

The Committee demands independent and objective assessments of the Company’s standards of behavior,

its compliance

with authorities, its financial reporting, and its business risks

systems, practices and controls from the auditors.

The Committee oversees audit activities with respect to the

following two (2) types of audits:

(a)

the

annual

audit

deals

with

the

fairness

of

the

statements,

compliance

of

transactions

with

specified

legal

authorities, and any other matter identified by the external

auditor as important,

(b)

the internal audit

(when established), which is

a part of

management’s system of internal

control, deals with

matters

similar to those of the annual audit.

The Committee reviews and follows the five (5) generic

phases of each of the two (2) types of audits:

1.

establishing the purpose and terms of reference for the audit;

2.

selection and organization of a team of experienced professionals

to plan and conduct the audit;

3.

conduct of the audit; and

4.

reviews all the audit results and findings, and reports to the

Board.

The Committee

shall review

management’s

plans to

correct any

significant

problems raised

by the

internal

and external

auditors. It shall monitor and review management’s

progress in implementing its response plan.

The Committee ensures that management has not placed any inappropriate restrictions on the audits and confirms that the

external auditor is independent and able to maintain

its objectivity.

The Committee approves the mandate of the internal audit function, monitors the long term internal

audit plan and ensures

that the internal auditor has adequate resources to perform its responsibilities and has direct and open communication with

the Committee. It

reviews the reporting

relationship of the

internal auditor to

ensure that an

appropriate segregation of

duties

is maintained and

that the internal

auditor has an

obligation to report

directly to the

Committee on matters

affecting its duties,

irrespective of his or her reporting relationships.

The Committee

evaluates the

work of

each of

the auditors

with a

view to

determining the

level of

assurance that

can be

derived from their work.

Table

of Contents

54

Periodically, the Committee

evaluates the performance of each auditor.

The Committee shall establish effective communication processes with management and the Company’s auditors, to

assist

it in monitoring objectively the quality and

effectiveness of the relationship among

the auditors, management and the Audit

Committee. It shall be responsible for the resolution of

disagreements between management and auditors.

OPERATIONAL RESPONSIBILITIES

Each

new

member

will

receive

an

orientation

about

the

Committee’s

work

and

responsibilities

and

all

members

are

encouraged to keep current about

and practices. In recognition of

the

importance of the

financial literacy skills

of its members,

the Committee relies

on the full support

of the Board

in acquiring

and in developing an approach to improve the necessary

skills, when required.

Annually,

the Committee

reviews the

Charter setting

out the

scope of

its responsibilities,

and, where

in the

opinion of

the

Committee, amendments

to the Charter

are required,

may propose such

amendments to

the Board for

consideration and

approval.

Annually, the Committee

will consider the appropriateness of preparing a report

to the Board describing its work.

care,

diligence

and

skill

that

a

and

FORWARD-LOOKING

STATEMENTS

acquisitions;

potential

business

partnering;

litigation;

and

plans

and

objectives.

In

certain

cases,

forward-looking

be

taken”,

“occur”

or

“be

achieved” and similar words or the negative thereof. Although management of the Company

believes that the expectations

represented

in

such

forward-looking

statements

are

reasonable,

there

can

be

no

assurance

that

such

will

prove to be correct.

In particular, this MD&A contains

forward-looking statements that relate, but are not limited,

to:

the Company’s business strategies, strategic objectives

and growth strategy;

the Company’s current and future capital resources

and the need for additional financing;

the Company’s

ability to

increase sales,

including the

results of

the successful

completion

of the

Company’s

current projects;

management’s

expectation

that the

Company will

achieve sustained

annual growth

and profitability,

and that

gross margins will increase resulting in a decrease in cost

of sales as a percentage of revenue; and

the Company’s overall financial performance.

By their

nature, forward-looking statements

require assumptions and

are subject

to inherent

risks and uncertainties

including

those discussed herein. In particular,

forward-looking statements relating to future sales,

growth and profitability are based

on the assumption that

current projects will

be completed, and

the Company will

be awarded certain

anticipated contracts

pursuant to

recent negotiations

with, and

statements

made by,

third parties.

There is

significant risk

that predictions

and

other

forward-looking

statements

will

not

prove

to

be

accurate.

Readers

are

cautioned

to

not

place

undue

reliance

on

forward-looking statements made herein because a number of factors could cause actual future results, conditions, actions

or

events

to

differ

materially

from

the

targets,

expectations,

estimates

or

intentions

expressed

in

the

forward-looking

statements.

Many factors could

cause the Company

’s actual

results, performance

or achievements

to be materially

different from

any

future results,

performance or

achievements that

may be

expressed or

implied by

forward-looking statements,

including,

without limitation,

risks

and uncertainties

relating to:

the strength

of the

Canadian,

US, European

and Asian

economies;

operational, funding,

and liquidity

risks; unforeseen

engineering and

environmental problems;

delays or

inability to

obtain

required

financing

and/or

anticipated

contracts;

risks

associated

with

licenses,

permits

and

regulatory

approvals;

supply

interruptions or labour disputes;

the impact of the Coronavir

us (COVID-19) pandemic on

our business and our operations;

foreign

exchange

fluctuations

and

collection

risk;

competition

from

other

suppliers,

or

alternative,

capital

intensive,

solutions;

and

risk

factors

described

elsewhere

under

the

heading

“Risk

Factors”

in

this

MD&A

and

the

Annual

Information Form, and

elsewhere in this

MD&A and other

filings that the

Company has

made and may

make in the

future

with

applicable

securities

regulatory

authorities.

We

caution

that

the

foregoing

list

of factors

is not

exhaustive,

and

that,

when relying

on forward-looking

statements to

make decisions

with respect

to the Company,

investors and

others should

carefully consider these factors, as well

as other uncertainties and potential events, and

the inherent uncertainty of forward-

looking statements.

Although

the

Company

has

attempted

to

identify

significant

factors

that

could

cause

actions,

events

or

results

to

differ

materially

from

those

described

in

forward-looking

statements,

there

may be

other

factors

that

cause

actions,

events

or

results

not

to

be

as anticipated,

estimated

or

intended.

There

can be

no

assurance

that

forward-looking

statements

will

prove to be accurate,

as actual results

and future events

could differ materially

from those anticipated in

such statements.

Accordingly,

readers

should

not

place

undue

reliance

on

forward-looking

statements.

Forward-looking

statements

are

provided as

of the

date of

this MD&A,

and the

Company assumes

no obligation

to update

or revise

such forward-looking

statements to reflect new events or circumstances except as

required under applicable securities laws.

The forward-looking statements

contained herein are expressly

qualified in their entirety

by this cautionary statement.

The

forward-looking statements included in

this MD&A are made

as of the

date of this

MD&A or such

other date specified

herein.

BASIS OF PRESENTATION

For reporting purposes, we prepared the 2022 consolidated financial

statements in accordance with International Financial

Reporting

Standards

(“IFRS”)

as

issued

by

the

International

Accounting

Standards

Board.

The

financial

information

contained

in

this

MD&A

was

derived

from

the

2022

consolidated

financial

statements.

Unless

otherwise

indicated,

all

references to “$” are to Canadian dollars. Unless otherwise indicated, all references to a

specific “note” refer to the notes to

the

2022

consolidated

financial

statements.

Certain

totals,

subtotals

and percentages

throughout

this

MD&A

may

not

reconcile due to rounding.

NON-IFRS MEASURES

This MD&A

makes reference

to certain

non-IFRS measures.

These measures

are not

recognized measures

under IFRS

and

do

not

have

a

standardized

meaning

prescribed

by

IFRS

and

are

therefore

unlikely

to

be

comparable

to

similar

measures presented

by other

companies. Rather,

these measures

are provided

as additional

information to

complement

those

IFRS

measures

by

providing

further

understanding

of

our

results

of

operations

from

management’s

perspective.

Accordingly, these measures should

not be

considered in isolation

nor as

a substitute for

analysis of our

financial information

reported under IFRS.

We use

non-IFRS measures,

including EBITDA

and Modified

EBITDA, both

of which are

not considered

an alternative

to

income or loss from operations, or to net earnings or loss,

in the context of measuring a company’s performance.

EBITDA

is used by

management in order

to facilitate operating

performance comparisons from

period to period,

to prepare annual

operating budgets and forecasts and to determine components of management compensation.

Management believes that

EBITDA is used

by investors

as it provides

supplemental measures

of operating performance

and thus highlight

trends in

our business that may not otherwise be apparent when relying solely on IFRS measures, and to compare the results of our

operations with other entities with

similar structures. Modified EBITDA is used

control

of

the

Company.

Management

believes

that

investors

use

Modified

EBITDA

for

similar

purposes

as

management and to evaluate performance while adjusting for non-cash discretionary expenses. Modified EBITDA allows a

more appropriate

comparison to

other companies

whose earnings

or loss

is not

adjusted by

fair value

adjustments from

strategic investments.

The Company also uses

Backlog

” or “

Backlog of signed

and/or awarded contracts

” interchangeably,

as a non-IFRS measure. Backlog figures allow management

of the Company to foresee and predict their future

needs and

resource

planning.

Management

believes

that

“Backlog”

is

used

by

investors

to

evaluate

the

Company,

their

future

performance and better understand the production capacity.

EBITDA:

We define EBITDA as net earnings before net

financing costs, income taxes, depreciation and

amortization. See

“Results of Operations - Reconciliation of Non-IFRS measures

(EBITDA and Modified EBITDA)”.

Modified EBITDA:

We defined Modified EBITDA as EBITDA and adjust for non-cash items namely share-based payments

the Company expects

to do so in 2023

and

Biogas upgrading and pollution controls related sales decreased by $3.1

million due to clients requesting additional

modifications prior to installation and commissioning, as

well as continuous testing to achieve desired results.

Fiscal 2022 revenues decreased by $12.1 million, mainly as a result

of:

DROSRITE™

million

due

to

client

delays

in

of the

Support services related to systems supplied for the US Navy

decreased by $6.2 million due to the project nearing

its completion with remaining

milestones based largely

on inspections and shipment

of the equipment,

as well as,

additional out of scope work costs incurred and not yet reflected

in receipt of purchase order modifications,

and

Biogas upgrading and pollution controls

decreased by $3.4 million due to

the continuous effort in reaching

desired

results in order to advance to final steps, such as, commissioning.

in the

future related

to backlog

be recognized

as the

Company satisfies its

performance obligations under

long-term contracts,

which is expected to occur over a maximum period of

approximately 3 years.

Cost of sales

$2.8 million in

Q4, 2022, representing

a decrease of

52% compared to

$5.9 million in

Q4,

decreases in subcontracting

$0.1 million (Q4, 2021

$0.2

million,

(Q4,

which

is

largely

due

to

the

decrease

in

product

revenues, as well as being negatively

impacted by the foreign exchange charge

on materials, and a decrease in

investment

tax credits ($0.02 million)

due to a lower levels of qualifying projects.

Fiscal 2022,

cost of

sales and

services

was $10.9

million,

representing

a decrease

of 42%

compared to

$18.6 million

in

2021, primarily due

to the

decrease of product

and service-related revenues

in the Company

and its

subsidiaries.

Decreases

in direct materials $4.7 million (2021 - $14.3 million)

and investment tax credits ($0.07 million)

(2021 – ($0.1 million)), were

offset by the increases

in employee compensation $3.7

million (2021

  • $2.6 million), subcontracting $1.3

million (2021 - $0.9

million),

manufacturing

overhead &

other

$1.4

million

(2021 -

$1.1

million),

foreign

exchange

charge

on

materials

($1.0

million) (2021

– ($0.6

million), totaling

an increase

of $5.4

million compared

to $4.1 million

in 2021.

The increase in

employee

compensation,

subcontracting,

and

manufacturing

overhead

& other

is primarily

related to

an

increase

in labour

intense

projects,

which require additional engineering hours,

as well as specific subcontracting work

related to equipment capacity

improvements, mainly for

torch-related sales, and

the increase to

manufacturing and

other was due

to higher utility

costs,

and

equipment

rentals,

such

as

cranes

and

power

generators.

These

increases

were

offset

by

the

decrease

in

direct

materials and by the foreign exchange charge on materials.

The gross margin for Q4,

2022 was $0.5 million or

14.5%

of revenue compared to a gross

margin of $1.3 million or

18.1%

of revenue for Q4,

2021, the decrease

in gross margin

was mainly attributable

to the negative

impact in foreign exchange

charge on materials of $0.5

million.

Fiscal 2022,

gross margin

was $8.1

million or

42.8% of

revenue compared

to a

gross margin

of $12.4

million or

40% for

fiscal 2021. As a result of the type of contracts being executed, the nature of the project activity, as well as the composition

of the

cost of

sales and

services, the

mix between

labour,

materials and

subcontracts

may be

significantly different.

The

cost of sales and services for 2022 and 2021 are

in line with management’s expectations and with the nature

of revenue.

Investment tax

credits recorded

against cost

of sales

are related

to projects

that qualify

for tax

credits from

the provincial

government of Quebec.

Qualifying tax credits

decreased in Q4,

2022 to $0.02

million compared to

$0.07 million for

Q4,2021.

In 2022,

$0.07 million

compared to

$0.1 million

in 2021.

The decrease

in fiscal

2022 is

primarily related

to less

contracts

being eligible for qualifying tax credits.

The amortization

of intangible

assets

for Q4,

2022 was

$0.2 million

compared

to $0.4

million for

Q4, 2021.

In 2022,

the

amortization of intangible

assets was

$0.9 million compared

to $0.5 million

for 2021. The

increase in 2022,

relates mainly

to the intangible assets in connection with

the Pyro Green-Gas acquisition, patents and deferred development costs. These

expenses are non-cash items

and will be amortized over the duration of the patent lives.

Included within Selling, General and Administrative expenses (“SG&A”) are costs associated with corporate administration,

business development, project proposals, operations

administration, investor relations and employee training.

SG&A expenses for Q4, 2022 were $10.4 million, representing a decrease

of 13%

compared to $11.9 million

for Q4, 2021.

The decrease is mainly a result of employee compensation decreasing to $2.5 million (Q4, 2021

– 4.6 million), due to lower

levels of eligible commissions and bonuses, a decrease in share-based compensation of $3.6 million

(a non- cash expense

related

to

a

Q4

2021

grant

not

repeated

in

2022),

and

a

decrease

in

other

expenses,

which

in

Q4

2021

comprised

of

insurances, taxes, interest, and bank charges.

Professional fees for Q4 2022 were greater due

to an increase in legal fees,

accounting fees,

investor relation

fees and

patent expenses. In

addition, in

Q4 2022

a credit

loss of

$4.5 million

was recorded

related to collection of accounts receivable, also a non-cash

expense.

SG&A expenses

for fiscal

2022 were

$29.0

million,

representing

an

increase

of

7% compared

to

$27.2

million for

fiscal

  1. The SG&A expense now includes

those of Pyro Green-Gas for the full year, versus approximately 5 months for fiscal

2021, increased due to the following:

i)

a

decrease

of

$0.6

million

in

employee

compensation

primarily

due

to

a

decrease

in

commissions

and

bonuses,

ii)

an increase of $1.3 million

for professional fees, primarily due

to an increase in consulting fees,

accounting

and audit fees, legal fees, investor relation fees and public

listing fees,

iii)

an

increase

of

$0.5

million

in

office

and

general

expenses,

is

primarily

due

to

information

technology

expenses including those related to the new ERP system

,

iv)

depreciation on property

and equipment increased

by $0.2 million

due to higher

amounts

of property and

equipment being depreciated,

v)

Bad debt

provision increased

by $4.5

million, of

which $4.2

million is

attributable to

accounts receivable

and $0.3 million related to costs and profits in excess

of billings on uncompleted contracts.

Separately,

share-based

payments

decreased

to

$1.3

million

for

Q4,

2022

(Q4,

2021

-

$4.9

and

decreased

$5,538,463

in

2022,

compared

to

$9,762,745

over

the

same

period

in

This

was

directly

impacted

by

the

vesting

structure of

months

ended

December

31,

2022,

the

Company

incurred

$0.7

million

of

R&D

expenses,

net

of

government grants, on internal projects in Q4 2022, a decrease of 36% compared to $1.1 million for the same period in the

prior year.

The Company

incurred $2.3 million

of R&D expenses,

net of government

grants, on

internal projects in

2022, a

decrease

of 9% compared to $2.5 million in 2021. The

decrease in 2022 is due to a decrease

in R&D activities, the type of contracts

being executed, the nature of the project activity,

and the decrease in government grants of $Nil compared to ($0.1 million)

reported in 2021.

In addition to internally funded

R&D projects, the Company also

incurred R&D expenditures during

the execution of client-

funded projects. These expenses are

eligible for Scientific Research and

Experimental Development (“SR&ED”) tax credits.

SR&ED tax credits on client-funded projects are applied against

cost of sales and services (see “Cost of Sales”

During the three

in 2021,

represents a

The variation

of $6.3 million

in the comprehensive

attributable to

the factors

described above, which have been summarized as follows, and includes

the profit and loss items of Pyro Green-Gas since

(i)

a decrease in product and service-related revenue of

$12.1 million arising in 2022,

(ii)

a

decrease

in

cost

of

sales

and

services

of

$7.8

million,

primarily

due

to

a

decrease

in

direct

materials,

and

investment tax credits,

(iii)

an increase in

SG&A expenses

of $1.8 million

arising in 2022

primarily due to

an increase in

professional fees,

office & general, travel, depreciation of property and

equipment, depreciation of ROU assets, government grants,

other expenses, and the allowance for credit loss of $4.5 million

,

(iv)

a

decrease

in

R&D

expenses

of

$0.2

million

primarily

related

to

the

decrease

in

government

grants

and

an

increase in investment tax credits,

(v)

a decrease in share-based expenses of $4.2 million,

(vi)

a decrease in changes in fair market value of strategic investments

and net finance costs of $12.9 million,

(vii)

a decrease in income taxes of $815,944.

In Q4 2022,

the comprehensive

loss is

$11.6

million favorable,

compared to

Q4 2021,

due to the

reasons detailed

above

and summarized

mainly as

the reduction

is revenue

of $3.9

million,

favorable impact

of SG&A

salaries and

share-based

expenses, offset

by the

allowance

for credit

loss

of $4.48

The

EBITDA

in

2022

was

a

$29.4

million

loss

compared

to

an

EBITDA

loss

of

$37.4

million

for

2021,

representing

n

decrease

of

21% year-over-year.

The

variation

in

the

EBITDA

in

2022

compared

to

2021

is

due

to

the

decrease

in

comprehensive

loss

of

$6.2

million,

offset

by

an

increase

in

depreciation

on

property

and

equipment

of

$0.2

million,

an

increase

in

depreciation

on

right-of-use

assets

of

$0.07

million,

an

increase

in

amortization

of

intangible

assets

of

$0.4

million, an increase in

finance charges of $0.1

million and an increase in

income taxes of $0.8

million.

The 2022 Q4 EBITDA

varied by $12.3 million mainly

due to the reduced

comprehensive loss in the

quarter, and

to the income tax reversal

in Q4

2021, which was not repeated in 2022.

The

Modified

EBITDA

in

2022

was

a

$15.5

million

loss

compared

to

a

Modified

EBITDA

loss

of

$6.2

million

for

2021,

representing

an

increased

loss

of

$9.3

million.

The

increase

in

the

Modified

EBITDA

loss

in

2022

is

attributable

to

the

decrease as mentioned above in the

EBITDA of $7.9 million and

a decrease in share-based expenses

of $4.2 million from

an expense not recurring

in 2022 and a decrease

in the change of

fair value of investments

of $13.1 million, based

on the

fair value of such

investment. The 2022

Q4 Modified EBITDA

is a loss of

$8.55 million which

is $2 million greater

than Q4

2021, due to the quarterly EBITDA variation explained above, a

decreased share-based expense in the current quarter and

a fair value of the strategic investment which remained stable,

based on the share price of the investment.

The majority of PyroGenesis’

revenue is recognised over the time of

the contract and is dependent on the

timing of project

initiation and execution, including project

engineering, manufacturing, and testing. Revenues in

2022 include revenues from

the sale

of intellectual

property

and

royalties

of $3.6

million ($3.3

million

in 2021)

and

$280,842.14

($315,846

in

2021),

respectively.

LIQUIDITY AND CAPITAL

RESOURCES

As at December 31, 2022, the Company had cash of $3.4

million, included in the net working capital of $1.7 million.

Certain

working capital

items such

as

Billings in

excess

of costs

and profits

on uncompleted

contracts

do not

represent

a direct

outflow

of

cash.

The

Company

expects

that

with

its

cash,

liquidity

position,

the

proceeds

available

from

the

strategic

investment and access to capital markets it will be able

to finance its operations for the foreseeable future.

The Company’s

term

loan

balance

at December

31,

2022 was

$389,987,

and

the

increase

since

January

1, 2022,

was

mainly attributable to the additional proceeds received on the Economic Development

Agency of Canada loan. This loan is

interest free and will remain so, until

the balance is paid over the 60

month period ending March 2029. The average interest

expense on the other term loans was 7.2% in 2022 and in 2021. The Company does not expect changes to the structure of

term loans in

the next fiscal

year. The Company maintained two

credit facilities which

bear interest at

variable rates of

7.45%

and

8%

at

December

31,

2022.

The

Company

expects

to

reimburse

a

portion

of

the

credit

facilities

during

2023,

and

extending the due date of the remaining balance, while

maintaining the similar conditions.

On a year-to-date

basis, cash

flow used

by operating

activities was

$11.1

million compared

to $18.1

period in the

prior year. During the three months ended December

31, 2022, cash flow

used by operating activities

was $1.2

million compared to $1.8 million

for the same period in

the prior year.

The use of cash during

2022 consists of the net loss

of $32.2

million (2021

– net

loss of

$38.4

million) plus

adjustments

for operating

activities of

$16.6

of cash consisted of

net losses of $10.7

million (Q4,

2021 – net loss of $22.4 million) plus adjustments

for operating activities of $1.9 million (Q4, 2021 - $15.9 million), including

a net change in non-cash operating working capital items

of $7.8 million (Q4, 2021 – net change of $4.3 million).

Investing activities

resulted in

a use

of funds

of $0.4

million in

2022, compared

to a

net source

of funds

of $2.7

million in

2021

resulting

from

the

additions

to

property

equipment,

intangible

assets,

purchased

and

disposals

of

strategic

investments and

cash

acquired

through

the business

combination.

During

the

three

months ended

December

investing activities resulted in

a use of cash of

$0.1 million, compared to

a net source of funds

of $1.3 million for the

same

period

in

the

prior

year.

For

Q4

2022

and

fiscal

2022,

the

variation

was

mainly

due

to

less

purchases

of

property

and

equipment as

equipment under construction

was complete, and

also from

the variation of

purchases and disposals

of shares

of the strategic investment.

Financing activities

in 2022

resulted in

a net

source of

funds of

$2.6 million,

compared with

a net

source of

funds of

$9.5

million for the same period in 2021.

In 2022, the Company issued common shares for net

cash proceeds of $2.7 million and

amount of

$0.7 million

in loans

and lease

liabilities. In

2021, the

Financing activities also include interest paid of $0.5 million in 2022 compared

to $0.3

fiscal 2022, the proceeds

from the credit facilities

represent a cash inflow

of $1 million. During

financing activities

resulted in

a net

source of

$2.3 million

due partly

to the

CAPITAL STOCK

INFORMATION

The authorized

share capital

of the

Company consists

of an

unlimited number

of common

shares. As

at March 30,

2023

PyroGenesis had 178,580,395 Common Shares, 6,014,600 share purchase warrants, 9,815,000 outstanding stock options

issued, and 6,473,000 exercisable options issued.

GOING CONCERN

These

consolidated

financial

statements

have

been

prepared

on

the

going

concern

basis,

which

presumes

that

the

Company will be

able to continue

its operations for

the foreseeable and

will be able

to realize its

assets and

discharge its

liabilities in the normal course of business for the foreseeable

future.

The Company is

subject to certain

risks and uncertainty

associated with the

achievement of profitable

operations such

as

the successful signing and delivery of contracts and access

to adequate financing.

The Company

has incurred,

in the

last years,

operating losses

and negative

cash flows

from operations,

and as

a result,

the Company has

an accumulated deficit of

$93,384,858 as at

December 31, 2022 ($61,217,831

as at December

31, 2021).

Furthermore, there have been unexpected delays in the collection of certain accounts receivable from contracts closed in a

prior year. This has

resulted in a

shortfall in cash

flows from operating

activities that would

be used in

funding the Company’s

operations.

As

at

December

31,

2022,

the

Company

has

working

capital

of

$1,650,709

($14,006,785

as

at

December

31,

2021)

including cash and

cash equivalents

of $3,445,649 ($12,202,513

as at December

31, 2021). The

working capital

is net of

an allowance for credit losses amounting to $5,023,283

($520,000 as at December 31, 2021) as further

described in notes

9 and 10. The Company’s

business plan is dependent

upon the successful completion

of contracts and also

the receipt of

payments from certain contracts

closed in a prior year and expects

these payments to be made

during fiscal 2023, as well

as

the

achievement

of

profitable

operations

through

the

signing,

completion

and

delivery

of

additional

contracts

or

a

reduction in certain operating expenses. In the absence of this, the Company is dependent upon raising additional funds to

finance operations within

and beyond the next

twelve months. The Company

has been successful

in securing financing in

the past

and has

relied upon

external financing

to fund

its operations,

primarily

through the

issuance of

equity,

debt and

convertible debentures.

The Company

completed a

private placement

in October

2022 for

an amount

of $1,318,980

and

also

completed

another

private

placement

in

March

2023

for

$5,000,000

(see

note

33).

While

the

Company

has

been

successful in securing

financing, raising

additional funds

is dependent

on a number

of factors, some

of which

are outside

the Company’s

control, and therefore

there is no

assurance that

it will be

able to do

so in the

future or that

these sources

will

be

available

to

the

Company

or

that

they

will

be

available

on

terms

which

are

acceptable

to

the

Company.

These

conditions indicate

the existence

of a

material uncertainty

that may

cast significant

doubt about

the Company’s

ability to

continue operating as a going concern.

The consolidated financial

statements have been

prepared on a

going concern

basis and do

not include

any adjustments

to the amounts and to classifications of the assets and liabilities that might be necessary should the Company be unable to

achieve its plan and continue in business. If the going concern assumption were not appropriate, adjustments,

which could

be material, would be necessary to the carrying value of assets and liabilities, the reported expenses, and the classification

of items on the consolidated statement of financial position.

CONTROLS AND PROCEDURES

The Company’s

shares

are traded

on the

Toronto

Stock

Exchange (“TSX”)

since

November

2020 and

on the

NASDAQ

since March 2021. Prior to November 2020, the Company’s shares traded on the TSX Venture Exchange (“TSXV”), and all

requirements of the TSXV were attainted by the

Company. The

Company acknowledged that being listed

on the TSX, and

NASDAQ would require more stringent disclosure controls, and

started implementing such before the NASDAQ listing.

As a

result of

the

graduation

to the

TSX and

NASDAQ,

the Company

became

subject

to additional

requirements

under

applicable securities

laws relating

to the

establishment and

maintenance of

disclosure controls

and procedures

(“DC&P”)

and internal control over financial reporting (“ICFR”),

as defined in NI 52-109 and the applicable rules of the U.S. Securities

and Exchange Commission.

Such requirements also

include the assessment

and evaluation of

both DC&P and

ICFR, which

was not required

while the Company was

listed on the

TSXV. Consequently,

the Company continues to

take several actions

to improve

its DC&P

and ICFR,

in accordance

with the

thresholds provided

by the

regulators. The

Company

is currently

implementing measures

designed to

improve its

ICFR environment

and remediate

the control

deficiencies that

led to

the

material weaknesses identified below.

In accordance with the provisions of National Instrument 52-109

– Issuers’

annual and interim filings (“NI 52-109”) adopted

by Canadian securities regulators and in Rule 13a-15(e) and 15d-15(e) under the U.S.

Securities Exchange Act of 1934, as

amended (the “Exchange Act”), the Company has filed certificates signed by the Chief Executive Officer (“CEO”) and Chief

Financial Officer

(“CFO”) that

report on,

among other

items, i)

their responsibility

for establishing

and maintaining

DC&P

and ICFR for the Company,

ii) the design of DC&P and the design of ICFR, and the effecti

veness of DC&P and ICFR.

Disclosure controls and procedures

The

Company

under

the

supervision

of

the

CEO

and

CFO,

have

designed

DC&P

(as

defined

in

NI-52-109

and

Rule 13a-15(e) and 15d-15(e) under the Exchange Act),

in order to provide reasonable assurance that:

material information relating to the Company is made

known to the CEO and CFO by others; and

information required to

be disclosed by

the Company in

its filings, under

applicable securities legislation is

recorded,

processed, summarized and reported within the time periods

specified in securities legislation.

As of

December 31, 2022,

an evaluation

was carried

out under

the supervision

of the

CEO and

CFO, of

the design

and

operating effectiveness

of the

Company’s DC&P.

Based on

this evaluation,

the CEO

and CFO

concluded that

due to

the

material weaknesses in our

ICFR as described below

in Management’s

Annual Report on Internal

Controls over Financial

Reporting, the Company’s DC&P were not effective

as of December 31, 2022.

Management’s Annual Report on Internal Controls

over Financial Reporting

The Company

under the

supervision of

the CEO

and CFO,

are responsible

to design

ICFR (as

defined in

NI-52-109 and

Rules 13a-15(f) and 15d-15(f) under the Exchange Act) in order to provide

reasonable assurance regarding the reliability of

financial reporting and the

preparation of consolidated financial

statements for external purposes

in accordance with IFRS

as issued by the IASB.

As

of

December 31,

2022,

an

evaluation

was

carried

out,

under

the

supervision

of

the

CEO

and

the

CFO,

of

the

effectiveness of the Company’s ICFR.

Based on this

evaluation, the CEO and

the CFO concluded that

material weaknesses

exist, as described below, and due to these material weaknesses, the Company’s ICFR is not effective as of December 31,

  1. The

control framework

used to

design and

evaluate effectiveness

of the

Company’s ICFR

is established

under the

criteria set forth by the Committee of Sponsoring

Organizations of the Treadway Commission (COSO) on Internal Control –

Integrated Framework (2013 framework). A

material weakness is a

deficiency, or combination of deficiencies, in ICFR, such

that there is a reasonable possibility that a material

misstatement of the Company’s annual or interim consolidated financial

statements will not be prevented or detected on a timely

basis.

In connection with the Company’s

evaluation of ICFR, the following

are the control deficiencies that

were considered to be

material weaknesses in the current year,

and in 2021 and any remediation that occurred during fiscal

2022:

Control

environment:

The

Company

did

not

maintain

an

effective

control

environment

and

has

identified

deficiencies relating

to appropriate

organizational structure

and authority

and responsibilities

.

The Company

did

not

have

a

sufficient

number

of

trained

resources

with

the

appropriate

skills

and

knowledge

with

assigned

responsibilities and accountability for the design and operation of ICFR and for holding

individuals accountable for

their internal control-related responsibilities.

Nonetheless, during

a portion

of 2022,

the deficiencies

related to

the control

environment over

reporting lines

as

well as authority

and responsibilities were

improved with the

implementation of additional

controls. Oversight

and

governance

of

financial

reporting

and

related

party

transactions,

including

the

oversight

executed

by

Board

of

Directors

and

the

Audit

Committee

was

not

indicative

of

a

control

environment

deficiency.

The

Company

has

financial

reporting

resources

internally,

or

at

their

disposal

to

ensure

they

can

deal

with

complex

accounting

matters, as well as period-end controls to mitigate the risk

of misstatement in the financial information.

Control activities:

The Company

did not fully

design and implement

effective control

activities and has

identified

deficiencies

relating

to:

(i) selecting

and

developing

control

activities

that

contribute

to

the

mitigation

of

risks

to

acceptable

levels,

and

(ii) deploying

control

activities

through

policies

that

establish

what

is

expected

and

procedures that put policies into action.

During 2022, the Company continued to implement numerous internal controls, including compensating

controls to

mitigate these risks

as well as adding

sufficient levels

of review and approval

in order to reduce

the risk related to

control activities thereby improving the quality of financial

information.

Journal

Entries:

The

Company

did

not

effectively

design

and

maintain

appropriate

segregation

of

duties

and

controls

over

the

effective

preparation,

review

and

approval,

and

associated

documentation

of

journal

entries,

across

its

ERP

platform.

The

Company

did

not

have

adequate

review

procedures

for

the

recording

of

manual

entries.

Throughout

2022

however,

the

Company

continues

to

modify

their

processes

to

ensure

that

journal

entries

are

sufficiently reviewed

and approved,

and compensating

controls exist

to ensure

the financial

information is

free of

misstatement.

Complex

Spreadsheet

Controls:

The Company

did

not implement

and

maintain

effective

controls

surrounding

certain

complex

spreadsheets,

including

addressing

all

identified

risks

associated

with

manual

data

entry,

completeness of data entry,

and the accuracy of mathematical

formulas, impacting complex spreadsheets

used in

fixed

asset

continuity

schedules,

production

and

revenue

forecasting,

and

the

calculation

of

the

fair

value

of

investments.

During the course of 2022, the

Company continued to improve the safeguarding of spreadsheets and data,

through

various

controls,

password

protections

and

improved

segregation

of

duties

with

the

objective

of

reducing

the

possibility of error.

User Access

Controls:

The Company

did not maintain

effective user

access controls

to adequately

restrict user

access to financial applications and related data in accordance

with job responsibilities,

for the entirety of 2022.

In

response

to

this,

the

Company

has

continued

to

implement

controls

to

limit

the

access

to

financial

and

non-

financial

applications,

based

on

employee

profile.

The

Company

continues

to

implement

IT

environment

best

practices

for

access

controls,

including

prompt

changes,

access

limitation

to

appropriate

users

and

systematic

periodic reviews of account privileges. Automated access

controls are being integrated into the new ERP system.

As a

consequence, the Company

did not have

effective control activities

related to the

design, implementation and operation

of process-level

and management

review control

activities related

to order-to-cash

(including revenue

trade

receivables,

and billings

in excess

of cost/cost

in excess

of billings), procure-to-pay

(including operating

expenses, prepaid

expenses,

accounts payable, and

accrued liabilities), hire-to-pay

(including compensation

expense and accrued

liabilities), long-lived

assets,

significant

unusual

transactions,

related

party

transactions

and

other

financial

reporting

processes

for

the

entire

year.

Aside from these material weaknesses, management has concluded that the Company’s consolidated financial statements

as at and for

the year ended December

31, 2022, present

fairly,

in all material

respects, the Company’s

financial position,

results of operations,

changes in shareholders’

equity and cash

flows in accordance

with IFRS as

issued by the

IASB. There

were no material adjustments to

the Company’s consolidated financial

statements for the year ended

December 31, 2022,

and

there

were

no

changes

to

previously

released

financial

results.

However,

because

the

deficiencies

and

material

weaknesses create a reasonable possibility that

a material misstatement to our

consolidated financial statements would not

be prevented

or detected

on a

timely basis,

the CEO

and CFO concluded

that as

of December 31,

2022, the

Company’s

design and operation of ICFR and DC&P were not effective.

Management’s Ongoing Remediation

Measures

During the year

ended December

31, 2022,

and beyond,

management

initiated

and continues

to implement

remediation

measures

as

outlined

above,

in

the

2021

annual

MD&A

as

well

as

the

quarterly

MD&A’s

of

2022.

Management

has

performed

an

initial

risk

assessment

using

a

top-down,

risk-based

approach

with

respect

to

the

risks

of

material

misstatement of the

consolidated financial

statements. In

addition, compensating

controls have been

applied to the

areas

where the

risks of

material misstatement

are considered

moderate to

high, as

throughout the

various accounting

cycles.

The Company is

using and plans

to continue to

use outside resources

to strengthen the

business process documentation

and help with

management’s self-assessment

and testing

of internal controls.

In 2023, the

Company’s management,

with

oversight of the Audit Committee expects to

advance the documenting, testing, and refining the internal

controls, in addition

with the upgrade to the ERP system, which inherently will add additional automated controls.

As a result, the Company will

improve

the

design

of

control

activities

and

strengthen

process

controls

surrounding

sales,

purchases,

payroll,

among

others, and will be call for fewer compensating controls.

Although

the

Company

can

give

no

assurance

that

these

actions

will

remediate

these

material

weaknesses

in

internal

controls or

that additional

material weaknesses

in our

ICFR will

not be

identified in

the future,

management believes

the

foregoing efforts will,

when implemented, strengthen

our ICFR and DC&P

and effectively remediate

the identified material

weaknesses.

Management

will

take

additional

remedial

actions

as

necessary

as

they

continue

to

evaluate

and

work

to

improve

the

Company’s ICFR environment.

Changes in internal controls over financial reporting

Other

than

the

material

weaknesses

described

above,

and

the

remediation

process

described

above,

there

were

no

changes to the

Company’s ICFR during the year ended December 31,

2022 that have materially

affected, or are reasonably

likely to materially affect, the Company’s ICFR.

Limitations on Effectiveness of Disclosure Controls and Procedures

and Internal Control over Financial Reporting

The Company’s management recognizes

that any DC&P

and ICFR, no

matter how well

designed and operated, can

provide

only reasonable

assurance

of achieving

their objectives.

Because of

their

inherent limitations,

DC&P

and ICFR

may not

prevent or detect all errors or misstatements on a timely

basis.

RISK FACTORS

The Company has

identified below certain

significant risks relating to

the business of

the Company and the

industry in which

it operates. The following information is only a summary of certain risk factors and is qualified in its entirety by reference to,

and

must

be

read

in

conjunction

with,

the

detailed

information

appearing

elsewhere

in

this

MD&A.

These

risks

and

uncertainties

are

not

the

only

ones

facing

the

Company.

Additional

risks

and

uncertainties

not

currently

known

to

the

Company, or that the Company currently considers immaterial, may also impair the operations of the Company. If any such

risks

materialize

into

actual

events

or

circumstances,

the

Company’s

assets,

liabilities,

financial

condition,

results

of

operations (including future

results of

operations), business and

business prospects, are

likely to

be materially

and adversely

affected. There is no assurance

that risk management steps

taken will avoid future loss due

to the uncertainties described

below

or

other

unforeseen

risks.

An

investment

in

the

Common

Shares

or

other

securities

of

the

Company

is

highly

speculative

and

involves

a

high

degree

of

risk.

Before

making

any

investment

decision,

prospective

investors

should

carefully consider all the information contained in this document

including, in particular, the

risk factors described below.

Certain factors may

have a material

adverse effect on

the Company’s business, financial

condition and results

of operations.

Current and prospective

investors should carefully

consider the risks

and uncertainties and

other information contained

in

this MD&A,

the 2022

consolidated Financial

Statements and

the Annual

Information Form,

particularly under

the heading

“Risk Factors” in the Annual Information Form, and in other filings that the Company has made and may make in the future

with applicable securities

authorities, Company’s

website at www.pyrogenesis.com.

The risks and

uncertainties described

herein and

therein are

not the

only ones

the Company

may face.

Additional risks

and uncertainties

that the

Company is

unaware of,

or that

the Company currently

believes are not

material, may also

become important

factors that

could adversely

affect the Company

’s business.

If any of

such risks actually

occur,

the Company’s

business, financial condition,

results of

operations, and future prospects could be materially and adversely affected. In that event, the trading price of the Common

Shares (or the value of any

other securities of the Company)

could decline, and the Company

’s securityholders could lose

part or all of their investment.

Risks Related to the Company’s Business and

Industry

Operating Income (Loss) and Negative Operating Cash

Flow

Prior

to

December 31,

2022,

the

Company

had

a

history

of

losses

and

negative

cash

flows.

For

the year

ended

December 31, 2022,

the Company

has net

losses of

$32.2 million,

cash flows

used in operations

of $11.1

million, and an

accumulated deficit

of $93.4

million at

December 31, 2022.

To

the extent

that the

Company has

net losses

and negative

operating cash flow in future periods, it may need to allocate a portion of its cash reserves to fund such negative cash flow.

The Company may

also be required

to raise additional

funds through the

issuance of equity

or debt securities.

There can

be no assurance that

the Company will be

able to generate a

positive cash flow

from its operations,

that additional capital

or

other

types

of

financing

will

be

available

when

needed

or

that

these

financings

will

be

on

terms

favourable

to

the

Company.

The Company’s ability to continue as

a going concern is dependent

upon its ability in the

future to grow its revenue,

achieve

profitable operations, successfully developing and introducing

new products and, in the meantime, to obtain

the necessary

financing to meet its obligations and repay its liabilities when they become due. While the

Company has been successful in

securing financing in the past, raising additional funds is dependent

on a number of factors outside the Company’s

control,

and as such

there is no

assurance that it

will be able

to do so

in the future.

External financing, predominantly by

the issuance

of equity and debt,

might be, sought to finance

the operations of the Company;

however, there can be no certainty that such

funds will be available at terms acceptable to the

Company, or at all. If the Company is unable to obtain sufficient additional

financing,

it

may

have

to

curtail

operations

and

development

activities,

any

of

which

could

harm

the

business,

financial

condition and results of operations.

Actual Financial Position and Results of Operations May Differ

Materially from the Expectations of the Company’s

Management

The Company’s

actual financial

position and

results of

operations may

differ materially

from management’s

expectations.

The Company has experienced

some changes in its

operating plans and certain

delays in the timing

of its plans. As

a result,

the Company’s revenue, net income and

cash flow may differ materially from

the Company’s projected revenue, net income

and cash flow. The process for estimating the Company

’s revenue, net income and cash flow requires the use of judgment

in determining the appropriate assumptions and estimates. These estimates and assumptions

may be revised as additional

information

becomes

available and

as additional

analyses

are performed.

In addition,

the assumptions

used in

planning

may not prove to be accurate, and other factors may affect

the Company’s financial condition or results

of operations.

Revenue Risks

PyroGenesis may experience delays in achieving

revenues, particularly with plasma gasification projects which

have a long

sales

cycle.

Revenues

may

be

delayed

or

negatively

impacted

by

issues

encountered

by

the

Company

or

its

clients

including:

(i)

unforeseen engineering and/or environmental problems;

(ii)

delays or inability to obtain required financing, licenses, permits

and/or regulatory approvals;

(iii)

supply interruptions and/or labour disputes;

(iv)

foreign exchange fluctuations and/or collection risk; and

(v)

competition from other suppliers and/or alternative energy

solutions that are less capital intensive.

There

is

no

assurance

that

the

business

will

perform

as

expected

or

that

returns

from

the

business

will

support

the

expenditures needed to develop it.

Concentration Risk and Credit Risk

To

date, a small

number of customers

have accounted for

a majority of

PyroGenesis’

revenues. As its

business expands,

the

Company

expects

that

revenue

distribution

will

be

over

a

larger

number

of

different

customers.

For

the year

ended

December 31,

2022,

sales

of

PyroGenesis

to

its

two

principal

customers

accounted

for

approximately

52%

of

its

total

revenue. For

the year

ended

December 31,

2021, sales

to two

principal

customers

accounted for

approximately

79% of

PyroGenesis’

total

revenue.

The

loss

of,

or

a

reduction

in,

purchase

orders

or

anticipated

purchase

orders

from

PyroGenesis’ principal

customers could

have a

material adverse

effect

on its

business, financial

condition and

results of

operations.

Additionally,

if

one

of

PyroGenesis’

customers

is

unable

to

meet

its

commitments

to

PyroGenesis,

the

Company’s business, financial condition and results

of operations could be adversely affected.

As a result of the Drosrite

International Exclusive Agreement

and the Dross Processing

Service Agreement, the Company

generates

significant

revenues

from

payments

made

to

Drosrite

International

under

the

Dross

Processing

Service

Agreement.

The

Company

will

no

longer

receive

payments

under

such

arrangement

if

the

Dross

Processing

Service

Agreement, which involves

a third party

in a foreign

jurisdiction, is

terminated, which

could have a

material adverse

effect

on the business, financial condition and results of operations

of the Company.

Credit

risk

is

the

risk

that

one

party

to

a

financial

instrument

will

cause

a

financial

loss

for

the

other

party

by

failing

to

discharge an obligation.

The maximum credit

risk to which

the Company is

exposed as at

December 31, 2022

represents

the carrying amount

of cash

and cash equivalents,

accounts receivable

(except sales

tax receivable),

costs and

profits in

excess of billings on uncompleted contracts, deposits

and royalties receivable.

Cash and cash equivalents,

which only comprise guaranteed

investment certificates redeemable

on relatively short

notice

by the Company,

are held with major reputable financial institutions.

Management has established

a credit policy

under which each

new customer is

analysed individually

for creditworthiness

before

the

Company’s

payment

and

delivery

terms

and

conditions

are

offered.

The

Company’s

review

could

include

reviewing external ratings, if they are available,

financial statements, credit agency information,

industry information and in

some cases bank

references. The Company’s

exposure to credit

risk is mainly

influenced by the

individual characteristics

of each customer. In monitoring customer

credit risk, customers are

identified according to their

characteristics such as their

geographic location, industry,

trading history with the Company and existence of previous

financial difficulties.

The Company does not generally

require collateral or other security

from customers on accounts

receivable, however,

the

contract terms may include the

possibility of recourse in the

event of late payment. The

Company believes that there

is no

unusual exposure associated with the collection of these

receivables.

The credit risk associated with costs and profits in excess of billings on uncompleted contracts is similar to that of accounts

receivable, as these amounts are accumulated and converted to

accounts receivable as invoicing milestones are reached.

The royalties receivable

are due from

a company in

which the Company

has a strategic

investments. The Company

does

not have

collateral or

other security

associated with

the collection

of this

receivable. The

carrying amount

of the

royalties

receivable have been discounted to reflect the time value

of money and credit risk of the counterparty.

The deposits are

payments made

to suppliers

and entities from

which the Company

leases property.

The Company

does

not have collateral

or other security

associated with

the collection

of these deposits.

As at December

31, 2022 and

2021,

no loss

allowance has been

recognized in

connection with these

deposits and

the maximum exposure

is the

carrying amount

of these deposits.

During the

years 2022

and 2021,

provisions for

expected credit

losses were

recorded, however,

no amounts

of financial

assets have been written off. The accounts provisioned by

the loss are still subject to

enforcement activity in order to collect

the balances due.

Technology Development and Manufacturing

Capability Risks

PyroGenesis recently expanded into

new areas of

business and, as

a result, many

of the Company’s

products are at

various

stages of

the

development

cycle. The

Company

may be

unable to

commercialise

such products,

or it

may be

unable to

manufacture such products in a commercially viable manner.

Whilst management is confident in both its technology and in

its team

of experienced

engineers,

scientists and

technicians,

it cannot

know with

certainty,

which of

its products

will be

commercialised, when such products will be

commercialised, or whether such products will be

able to be manufactured and

distributed profitably.

Product Revenues/History of Losses

PyroGenesis has incurred losses in the majority of years since its inception. In

the past the Company’s operations have not

generated sufficient

earnings and

cash flows

to date

to result

in consistent

profitability or

positive cash

flow.

For the year

ended December 31, 2022, the Company

has a net loss of $32.2 million

which includes a loss from

the change in value of

strategic investment of $8.3 million and cash flows used

in operations of $11.1

million. There can be no assurance that the

Company will be able to continue to generate significant gains

from the value of its strategic investments in the

future.

Additional financing and dilution

PyroGenesis may require additional

financing. There can be

no assurance that additional

financing will be available

to the

Company when needed, or on terms acceptable to the

Company.

PyroGenesis’

inability

to

raise

financing

to

support

ongoing

operations

or

to

fund

capital

expenditures

could

limit

the

Company’s growth and may have a material adverse

effect upon the Company.

The Company does not

exclude raising additional funds by equity

financing. In addition, at March 30,

2023, 9,815,500 stock

options

are

currently

issued

and

outstanding,

together

with

6,014,600

share

purchase

warrants.

The

exercise

of

stock

options

and/or

warrants,

as

well

as

any

new

equity

financings,

represents

dilution

factors

for

present

and

future

shareholders.

Reliance on Third Party Suppliers, Service Providers, Distributors

and Manufacturers

The Company’s

direct and

indirect suppliers,

service providers,

distributors and

manufacturers may

elect, at

any time,

to

breach or otherwise cease

to participate in supply, service, distribution or

manufacturing agreements, or other relationships,

on which the Company’s operations rely. Loss of its suppliers, service providers, distributors and manufacturers could have

a material adverse effect

on the Company’s business

and operational results. Further,

any disruption in the manufacturing

process done

by third-party

manufacturers could

have a

material adverse

effect

on the

business, financial

condition and

results of operations of the Company.

The Company cannot ensure that alternative production

capacity would be available

in the event of a disruption, or if it would be available,

it could be obtained on favorable terms.

Manufacturing Facilities

The vast majority of the

Company’s products are

manufactured in its manufacturing

facilities located in Montreal,

Quebec,

as well as in

Italy and India.

Accordingly,

the Company is

highly dependent on the

uninterrupted and efficient

operation of

its manufacturing facilities. If for any reason

the Company is required to discontinue production at its

facilities, it could result

in significant delays in production of

the Company’s products and interruption of the Company’s sales as it

seeks to resume

production. The Company

may be unable

to resume production

on a timely

basis. If operations

at the facilities

were to be

disrupted

as

a

result

of

equipment

failures,

natural

disasters,

fires,

accidents,

work

stoppages,

power

outages

or

other

reasons, the Company’s business, financial condition

and/or results of operations could be materially adversely

affected.

Sales Cycle and Fixed Price Contracts

PyroGenesis sales

cycle is

long and

the signing

of new

contracts is

subject to

delay,

over which

the Company

has little

control. The Company

also enters into

sales contracts with fixed

pricing, which may be

impacted by changes

over the period

of implementation. There is no

assurance that delays or problems

in fulfilling contracts with clients will

not adversely affect

the Company’s activities, operating results or financial

position.

Reliance on Technology

PyroGenesis will depend

upon continuous improvements

in technology to

meet client demands

in respect of

performance

and cost, and to explore additional business opportunities. There can be no

assurance that the Company will be successful

in its efforts

in this regard or

that it will have

the resources available

to meet this demand.

Whilst management anticipates

that

the

research

and

development

will

allow

the

Company

to

explore

additional

business

opportunities,

there

is

no

guarantee that such

business opportunities

will be presented

or realized. The

commercial advantage

of the Company

will

depend to a

significant extent on

the intellectual property

and proprietary technology

of PyroGenesis and

the ability of

the

Company to

prevent others from

copying such proprietary

technologies. PyroGenesis currently

relies on intellectual

property

rights

and

other

contractual

or

proprietary

rights,

including

(without

limitation)

copyright,

trade

secrets,

confidential

procedures, contractual

provisions, licenses

and patents,

to protect

its proprietary

technology.

PyroGenesis may

have to

engage in litigation in order to protect its patents or other intellectual property rights, or to determine the validity or scope of

the proprietary rights

of others. This

type of litigation

can be expensive

and time consuming,

regardless of

whether or not

the Company is successful. PyroGenesis

may seek patents or other

similar protections in respect of particular

technology;

however, there can be no assurance that any future patent applications will actually result in issued patents, or that, even if

patents are issued,

they will be

of sufficient scope

or strength to

provide meaningful protection or

any commercial advantage

to the Company.

Moreover,

the process

of seeking

patent protection

can itself

be long

and expensive.

In the

meantime, competitors

may

develop technologies

that are

similar or

superior to

PyroGenesis’

technology or

design around

the patents

owned by

the

Company,

thereby

adversely

affecting

the

Company’s

competitive

advantage

in

one

or

more

of

its

areas

of

business.

Despite the efforts

of the Company,

its intellectual property

rights may be

invalidated, circumvented, challenged,

infringed

or required

to be

licensed to

others. It

cannot be

assured that

any steps

the Company

may take

to protect

its intellectual

property rights

and other rights

to such

proprietary technologies

that are central

to the Company

’s operations

will prevent

misappropriation or infringement of its technology.

Changes to Contracts

PyroGenesis is dependent upon its

ability to establish and develop

new relationships and to build

on existing relationships

with

current

clients.

The

Company

cannot

provide

assurance

that

it

will

be

successful

in

maintaining

or

advancing

its

relationships with

current clients

or procure

additional clients.

In addition,

PyroGenesis cannot

provide assurance

that its

customers and the end users of its products will continue to provide the Company with business, or that existing customers

and end users will not seek

to renegotiate or terminate existing

contracts providing for the sale

of the Company’s products

and technology based on circumstances on which the Company is not currently aware. Any termination or amendment of a

contract

under

which

the

Company

derives

an

important

portion

of

its

revenues,

including

the

Drosrite

International

Exclusive

Agreement

and

the

Dross

Processing

Service

Agreement,

and

any

adverse

change

in

the

relationship

of

the

Company with its customers and end users,

will have an adverse effect on the

Company’s business, financial condition and

results of operations.

Sales

to

governments

and

governmental

entities

are

subject

to

specific

additional

risks,

such

as

delays

in

funding,

termination of

contracts or

sub-contracts at

the convenience

of the

government,

termination, reduction

or modification

of

contracts or sub-contracts in

the event of changes

in the government’s

policies or as a result

of budgetary constraints and

increased or unexpected costs resulting in losses or reduced

profits under fixed price contracts.

Foreign Exchange Exposure

PyroGenesis’ products and

services are increasingly being

sold in markets outside

of Canada, whilst most

of its operating

expenses

and

capital

expenditures

are

denominated

in

Canadian

dollars.

As

a

result,

the

Company

is

exposed

to

fluctuations in the foreign

exchange rates between Canadian

dollar and the currency

in which a

particular sale is transacted,

which may

result in

foreign exchange

losses that

could affect

earnings. Foreign

sales are

predominantly denominated

in

U.S. dollars,

as well as the Euro

and Indian Rupee. The Company has

not to date sought to

hedge the risks associated with

fluctuations in foreign exchange rates.

Competition

The

industry

is

competitive

and

PyroGenesis

competes

with

a

substantial

number

of

companies

which

have

greater

technical

and

financial

resources.

There

can

be

no

assurance

that

such

competitors

will

not

substantially

increase

the

resources devoted to the development and marketing of products and services that compete

with those of the Company or

that

new

or

existing

competitors

will

not

enter

the

various

markets

in

which

PyroGenesis

is

active.

There

can

be

no

assurance that

competitors will

not develop

new and

unknown technologies

with which

the Company

may have

difficulty

competing. Furthermore, failure to remain cost competitive

may result in PyroGenesis losing business to its competitors.

The plasma technology of

PyroGenesis competes against other

plasma and conventional technologies.

Without limitation,

the demand for the plasma technology of PyroGenesis, particularly in waste destruction and waste-to-energy systems, can

be impacted by the

commodity prices of

the energy source

used for the process

and the price at

which waste is

accepted

by

landfills

and

traditional

waste

processing

plants.

While

the

Company

believes

that

demand

for

sustainable

waste

management practices

that have

lower environmental

impacts than

traditional solutions

such as

landfill or

incineration

is

increasing,

the

high

flows

of

electricity

necessary

to

operate

the

waste

destruction

and

waste-to-energy

systems

of

PyroGenesis have an

impact on the

operational costs

of the Company’s

systems, and traditional

solutions may

constitute

lower-cost solutions, particularly if commodity prices (including

of oil and natural gas) remain low or experience a decline.

Management and Key Personnel

PyroGenesis depends on the skills and experience of

its management team and other key employees. The

Company relies

heavily on its ability to attract and retain highly skilled personnel in a competitive environment. PyroGenesis may be unable

to recruit, retain, and motivate highly skilled employees in order to assist the Company’s

business, especially activities that

are essential

to the

success of

the Company.

Failure

to recruit

and retain

highly skilled

employees may

adversely affect

PyroGenesis’ business, financial condition and results of operations.

Implementation of a strategic plan

PyroGenesis’

commercial

strategy

aims

to

leverage

its

products,

consumables,

and

services

whilst

focusing

on

the

resolution of problems

within niche markets within

the industries served by

the Company.

There can be no

assurances as

to the

success

of the

Company’s

strategic

plan,

which

should

be considered

under

the risks

perspective

and

difficulties

frequently encountered by a developing business.

Adverse Decisions of Sovereign Governments

PyroGenesis

conducts

an

increasing

portion

of

its

business

internationally.

There

is

no

assurance

that

any

sovereign

government, including Canada’s, will

not establish laws or

regulations that will not

be detrimental to

the Company’s interests

or that, as a foreign corporation, it will continue

to have access to the regulatory agencies

in other countries. Governments

have,

from

time

to

time,

established

foreign

exchange

controls,

which

could

have

a

material

adverse

effect

on

the

Company’s business, financial condition and results

of operations.

Risks Related to International Operations

A

substantial

portion

of

the

Company’s

sales

are

made

to

customers

and

end

users

outside

Canada.

The

Company

conducts

its

international

operations

directly

or

through

distributors

or

other

agents

or

intermediaries,

including

Drosrite

International.

The

Company

plans

to

continue

to

expand

its

international

sales

and

marketing

efforts.

International

operations are

subject to

a number

of inherent

risks, and

the Company’s

future results

could be

adversely

affected by

a

number of factors, including:

unfavorable political

or economic

environments;

requirements

or preferences

for domestic

products or

solutions,

which could reduce demand for the Company’s products;

differing existing or future regulatory and certification

requirements;

unexpected legal or regulatory changes;

greater difficulty in collecting accounts receivable

and longer collection periods;

difficulties in enforcing contracts; an inability to

effectively protect intellectual property;

tariffs and trade

barriers, export regulations

and other

regulatory and

contractual limitations on

the Company’s ability

to sell its products; and

potentially adverse tax consequences, including multiple and

possibly overlapping tax structures.

Fluctuations in

currency exchange

rates could

materially adversely

affect sales

denominated in

currencies other

than the

Canadian dollar and cause a reduction in revenues derived from sales in a particular country. Financial instability in foreign

markets could

also affect

the sale

of the

Company’s

products in

international jurisdictions.

In addition,

the Company

may

be denied access to its

end customers as a result

of a closing of the

borders of the countries in which

it its products are sold

due to economic, legislative, political and military conditions

in such countries.

There can be no assurance that such factors will not materially adversely affect the operations, growth prospects and sales

of the Company and, consequently, its results of operations. In addition, revenues the Company earns in other jurisdictions

may be subject to

taxation by more than

one jurisdiction, which

could materially adversely

affect the Company’s

earnings.

Each of

these factors could

have an

adverse effect on

the Company’s business,

financial condition and

results of

operations.

Governmental Regulation

PyroGenesis is subject to a variety of federal, provincial, state, local

and international laws and regulations relating namely

to the

environment,

health

and safety,

export

controls,

currency

exchange, labour

and employment

and

taxation.

These

laws

and

regulations

are

complex,

change

frequently

and

have

tended

to

become

more

stringent

over

time.

Failure

to

comply with these laws

and regulations may

result in a variety

of administrative, civil

and criminal enforcement

measures,

including assessment

of monetary

penalties, imposition

of remedial

requirements and

issuance of

injunctions as

to future

compliance. The Company

may be subject to

compliance audits by regulatory

authorities in the various countries

in which

it operates.

Government-funded Defense and Security Programs

Like

most

companies

that

supply

products

and

services

to

governments,

government

agencies

routinely

audit

and

investigate government contractors. These agencies may review the Company’s performance under its contracts, business

processes, cost structure, and compliance

with applicable laws, regulations and

standards. The Company’s incurred

costs

for each year

are subject

to

audit

by government

agencies,

which

can

result

in

payment

demands

related

to costs

they

believe should be disallowed. The Company works with governments to assess the merits of claims and where appropriate

reserve for

amounts

disputed. The

Company

could

be required

to provide

repayments

to governments

and

may have

a

negative effect on its results of operations.

Contrary to cost-reimbursable

contracts, some costs

may not be reimbursed

or allowed under fixed

-price contracts, which

may have a negative effect on the Company’s

results of operations if it experiences costs

overruns.

Environmental Liability

PyroGenesis is subject to

various environmental laws and

regulations enacted in the

jurisdictions in which it

operates, which

govern the

manufacturing,

processing, importation,

transportation,

handling and

disposal of

certain materials

used in

the

Company’s operations. Management believes that it has adequate procedures

in place to address compliance with current

environmental laws and regulations. Furthermore, management monitors the

Company’s practices concerning the handling

of environmentally hazardous materials. However,

there can be no assurance that the

Company’s procedures

will prevent

environmental damage

occurring from

spills of

materials handled

by the

Company or

that

such

damage

has

not

already

occurred.

On

occasion,

substantial

liabilities

to

third

parties

may

be

incurred.

The

Company may

have the

benefit of

insurance maintained

by it

or the

operator,

however,

the Company

may become

liable

for damages against which it cannot

adequately insure or against which it may

elect not to insure because of

high costs or

other

reasons.

The

Company’s

clients

are

subject

to

similar

environmental

laws

and

regulations,

as

well

as

limits

on

emissions to the air and discharges into surface and sub-surface waters. While regulatory

developments that may follow in

subsequent years

could

have

the

effect

of

reducing

industry

activity,

the

Company

cannot

predict

the

nature

of

the

restrictions that may be imposed. The Company may be required to increase operating expenses or capital

expenditures in

order to comply with any new restrictions or regulations.

Product Liability and Other Lawsuits

PyroGenesis

is

subject

to

a

variety

of

potential

product

liabilities

claims

and

other

lawsuits

related

with

its

operations,

including

liabilities

and

expenses

associated

with

product

defects.

The

Company

maintains

product

liability

and

other

insurance coverage that management believes is generally

in accordance with the market practice in its industry,

but there

can be no assurance that the Company will always be adequately

insured against all such potential liabilities.

A

malfunction

or

the

inadequate

design

of

the

Company’s

products

could

result

in

product

liability

or

other

tort

claims.

Accidents involving

the Company

’s

products

could lead

to personal

injury or

physical damage.

Any liability

for damages

resulting from malfunctions could be substantial

and could materially adversely

affect the Company’s business

and results

of operations.

In addition,

a well-publicized

actual or

perceived problem

could adversely

affect the

market’s

perception of

the

Company’s

products.

This

could

result

in

a

decline

in

demand

for

the

Company’s

products,

which

would

materially

adversely affect the Company’s financial condition

and results of operations.

The sale and use of products and processes developed by the Company may entail potential liability and

possible warranty

claims. The Company

may be subject

to personal injury

claims for injuries

resulting from use

of its products.

Although the

Company maintains product liability insurance, there can be no assurance that such insurance will continue to be available

on commercially reasonable terms or that the risks covered,

or coverage amounts will be sufficient to cover

all claims.

Information systems disruptions

The Company relies on various

information technology systems to

manage its operations. Over

the last several years, the

Company has implemented, and it

continues to implement, modifications and

upgrades to such systems, including

changes

to legacy

systems,

replacing legacy

systems

with successor

systems with

new functionality,

and acquiring

new systems

PyroGenesis Canada Inc.

Management’s Discussion and Analysis

For the years ended December 31, 2022, and

2021

with new functionality.

These types of activities

subject the Company to

inherent costs and

risks associated with replacing

and changing these systems, including impairment of the Company’s ability to fulfill customer orders, potential disruption of

its internal control structure, substantial capital expenditures, additional administration and

operating expenses, retention of

sufficiently skilled

personnel to

implement and

operate the

new systems,

demands on

management time

and other

risks

and costs of delays or difficulties

in transitioning to or integrating new systems

into the Company’s current systems. These

implementations,

modifications,

and

upgrades

may not

result

in

productivity

improvements

at

a

level

that

outweighs

the

costs

of

implementation,

or

at

all.

In

addition,

the

difficulties

with

implementing

new

technology

systems

may

cause

disruptions in

the Company’s

business operations

and have

a material

adverse effect

on its business,

financial condition,

or results of operations.

Security Breaches

As part of its

day-to-day business, the Company stores its

data and certain data

about its customers in its

global information

technology system. Unauthorized

access to the

Company’s data, including

any regarding its customers,

could expose the

Company to a risk of loss of this

information, loss of business, litigation and possible liability. These security measures may

be breached by intentional misconduct by computer hackers, as a result of third-party action, employee error,

malfeasance

or otherwise. Additionally, third parties may attempt to fraudulently induce employees or customers into disclosing sensitive

information

such

as

usernames,

passwords

or

other

information

in

order

to

gain

access

to

the

data

of

the

Company’s

customers or

the Company’s data,

including the

Company’s intellectual property

and other

confidential business information,

or

the

Company’s

information

technology

systems.

Because

the

techniques

used

to

obtain

unauthorized

access,

or

to

sabotage systems, change

frequently and generally are

not recognized until launched

against a target, the

Company may

be unable to

anticipate these techniques or to

implement adequate preventative measures. Any

security breach could result

in a loss of

confidence by the

Company’s customers,

damage its reputation,

disrupt its business,

lead to legal

liability and

negatively impact its future sales.

Public Health Crises

Public

health

crises,

including

local,

regional,

national

or

international

outbreak

of

a

contagious

disease,

could

have

an

adverse effect on

local economies, the

global economy,

and the markets

in which the

Company operates

and markets its

products, and may

adversely impact the

price and demand

for the Company’s

products and the

ability of the

Company to

operate and market

its products. Any

such alterations or

modifications could cause

substantial interruption to

the Company’s

business, any

of which

could have

a material

adverse effect

on the

Company’s operations

or financial

results, and

could

include temporary closures of

one or more

of the Company’s or

its partner’s offices or

facilities; temporary or long-term

labor

shortages; temporary or long-term adverse impacts on the Company’s supply chain and distribution channels; the potential

of increased network vulnerability and

risk of data loss resulting

from increased use of remote

access and removal of data

from the Company’s facilities.

Subsequent

to

December 31,

2019,

the

global

emergence

of

coronavirus

(COVID-19)

occurred.

The

global

outbreak

of

COVID-19 has resulted in governments

worldwide enacting emergency measures to protect

against the spread of the

virus.

These

measures,

which

include,

among

other

things,

limitations

on

travel,

self-imposed

quarantine

periods

and

social

distancing measures,

have caused

material disruption

to businesses

globally resulting

in an

economic slowdown.

Global

equity markets

have

experienced

significant

volatility

and weakness.

Governments

and central

banks

have reacted

with

significant

monetary

and

fiscal

interventions

designed

to

stabilize

economic

conditions.

The

duration

and

impact

of

the

COVID-19 outbreak is unknown at this time, as is the efficacy of any government and/or central bank interventions. It is not

possible

to

reliably

estimate

the

length

and

severity

of

these

developments

and

the

impact

on

the

financial

results

and

condition of the Company in future periods.

As of

the date

of this

MD&A, the

Company has

successfully continued

operations under

COVID-19 protocols.

COVID-19

has

not

resulted

in

any

material

delays

in

the

development

or

testing

of

the

Company’s

products

or

any

other

material

development projects. The Company is not currently experiencing any delays or

interruptions in service or product delivery.

At the

outset of

the COVID-19

pandemic, certain

of the

Company’s operations

were negatively

impacted, but

have since

normalized.

The

Company

has

not

experienced

any

material

disruption

in

its

supply

chain,

and

the

pandemic

has

not

materially impacted the Company’s business

or delivery of services or products.

The Company’s

production schedule

has continued throughout

COVID-19 on

a modified

employee schedule,

with certain

non-production employees working remotely.

The Company has been able to

operate largely unaffected

by the COVID-19

pandemic. Notwithstanding the foregoing, if the Company or its vendors and suppliers are unable to continue operations or

keep up with increasing demands as a result of COVID-19, customers

may experience delays or interruptions in service or

the delivery

of products, which

may be detrimental

to the

Company’s reputation, business, results

of operations and

financial

position.

The

Company

cautions

that

it

is

impossible

to

fully

anticipate

or

quantify

the

effect

and

ultimate

impact

of

the

COVID-19 pandemic as the situation is rapidly evolving. The extent to which COVID

-19 impacts the Company’s results will

depend on

future developments,

which are

highly uncertain

and cannot

be predicted,

including new

information that

may

emerge concerning the

severity of COVID-19

and the actions

taken by governments

to contain it

or treat its

impact, including

shelter in place

directives, which,

if extended, may

impact the economies

in which the

Company now

operates, or may

in

the future operate,

key markets

into which the

Company sells

products and delivers

services, and markets

through which

the Company’s key suppliers source their products.

Litigation

The Company

may from

time to

time become

party to

litigation in

the ordinary

course of

business which

could adversely

affect

its business.

Should

any litigation

in

which

the

Company

becomes

involved

be determined

against the

Company,

such a

decision could

adversely affect

the Company’s

ability to

continue operating

and the

market price

for the

Common

Shares and

could use

significant resources.

Even if

the Company

is involved

in litigation

and wins,

litigation can

redirect

significant Company resources. Litigation may also create a

negative perception of the Company’s brand.

Trade Secrets May Be Difficult to Protect

The

Company’s

success

depends

upon

the

skills,

knowledge

and

experience

of

its

scientific

and

technical

personnel,

consultants and advisors,

as well as contractors.

Because the Company operates

in a highly competitive

industry,

it relies

in part on trade

secrets to protect its proprietary

products and processes. However, trade secrets are difficult to protect. The

Company

generally

enters

into

confidentiality

or

non-disclosure

agreements

with

its

corporate

partners,

employees,

consultants, outside

scientific collaborators,

developers and

other advisors.

These agreements

generally,

require that

the

receiving party keep confidential, and not disclose to third parties, confidential information developed by the receiving party

or

made

known

to

the

receiving

party

by

the

Company

during

the

course

of

the

receiving

party’s

relationship

with

the

Company.

These

agreements

also

generally

provide

that

inventions

conceived

by

the

receiving

party

in

the

course

of

rendering services to the

Company will be

its exclusive property,

and the Company

enters into assignment

agreements to

perfect its rights.

These confidentiality,

inventions, and

assignment agreements,

where in

place, may

be breached

and may

not effectively

assign intellectual

property rights

to the Company.

The Company’s

trade secrets

could also be

independently discovered

by competitors, in which

case the Company would

not be able to

prevent the use of

such trade secrets by

its competitors.

The enforcement

of a

claim alleging

that a

party illegally

obtained

and was

using the

Company’s

trade secrets

could be

difficult,

expensive

and

time

consuming

and

the

outcome

could

be

unpredictable.

The

failure

to

obtain

or

maintain

meaningful trade secret protection could adversely affect

the Company’s competitive position.

Risks Related to Acquiring Companies

The Company may acquire other companies

in the future and there are risks

inherent in any such acquisition.

Specifically,

there

could

be

unknown

or

undisclosed

risks

or

liabilities

of

such

companies

for

which

the

Company

is

not

sufficiently

indemnified.

Any

such

unknown

or

undisclosed

risks

or

liabilities

could

materially

and

adversely

affect

the

Company’s

financial

performance

and

results

of

operations.

The

Company

could

encounter

additional

transaction

and

integration-

related costs or other

factors such as the

failure to realize all

of the benefits from

such acquisitions. All of

these factors could

cause dilution to the Company’s

earnings per share or decrease

or delay the anticipated accretive

effect of the acquisition

and

cause

a

decrease

in

the

market

price

of

the

Company’s

securities.

The

Company

may

not

be

able

to

successfully

integrate

and

combine

the

operations,

personnel

and

technology

infrastructure

of

any

such

acquired

company

with

its

existing

operations.

If

integration

is

not

managed

successfully

by

the

Company’s

management,

the

Company

may

experience interruptions in its business activities, deterioration of its employee and customer relationships, increased costs

of

integration

and

harm

to

its reputation,

all

of which

could

have

a

material

adverse

effect

on

the

Company’s

business,

financial

condition

and

results

of

operations.

The

Company

may

experience

difficulties

in

combining

corporate

cultures,

maintaining

employee

morale

and

retaining

key

employees.

The

integration

of

any

such

acquired

companies

may

also

impose

substantial

demands

on

the

management.

There

is

no

assurance

that

these

acquisitions

will

be

successfully

integrated in a timely manner.

Management’s Discussion and Analysis

For the years ended December 31, 2022, and

Global Economic Uncertainty

Demand for

the Company’s

products and

services are

influenced by

general economic

and consumer

trends beyond

the

Company’s control. There can be no assurance that the Company’s business and corresponding financial performance will

not be adversely affected

by general economic or consumer

trends. In particular,

global economic conditions are still

tight,

and if such conditions continue,

recur or worsen, there can

be no assurance that they

will not have a

material adverse effect

on the Company’s business, financial condition and results

of operations.

Furthermore, such economic conditions have produced downward pressure on stock

prices and on the availability of credit

for financial

institutions

and corporations.

If these

levels of

market disruption

and

volatility continue,

the Company

might

experience reductions in business activity, increased funding costs and funding pressures, as applicable, a decrease in the

market price of the

Common Shares, a decrease in asset

values, additional write-downs and impairment charges and lower

profitability.

Inability to Renew Leases

The Company

may be

unable to

renew or

maintain its

leases (commercial

or real

property)

on commercially

acceptable

terms or

at all.

An inability

to renew

its leases,

or a

renewal of

its leases

with a

rental rate

higher than

the prevailing

rate

under

the

applicable

lease

prior

to

expiration,

may

have

an

adverse

impact

on

the

Company’s

operations,

including

disruption of

its operations

or an

increase in

its cost

of operations.

In addition,

in the

event of

non-renewal

of any

of the

Company’s

leases,

the

Company

may

be

unable

to

locate

suitable

replacement

properties

for

its

facilities

or

it

may

experience delays in relocation that could lead to a disruption in its operations. Any disruption in the Company’s operations

could have an adverse effect on its financial condition

and results of operations.

Financial Reporting and Other Public Issuer Requirements

As a public

company,

the Company is

subject to the

reporting requirements

of the Canadian

Securities Administrators,

or

the CSA, and the U.S. Securities Exchange Act of 1934,

as amended, and the rules and regulations of the listing standards

of the

TSX and

NASDAQ and

the U.S.

Sarbanes-Oxley Act.

The requirements

of these

laws, rules and

regulations have

increased

and

will

continue

to

increase

the

Company’s

legal,

accounting,

and

financial

compliance

costs,

make

some

activities more difficult, time-consuming, and costly, and place significant strain on the Company’s personnel, systems, and

resources. The Company is continuing to develop and refine its disclosure controls and other procedures that

are designed

to ensure that

information required to

be disclosed by

the Company in

the reports that

it will file with

the CSA is recorded,

processed, summarized, and

reported within the

time periods specified

in CSA rules and

forms and that

information required

to be

disclosed in

reports under

applicable securities

laws is

accumulated and

communicated to

the Company’s

principal

executive and

financial officers.

The Company

is also

continuing to improve

its internal

control over

financial reporting.

In

order to improve the effectiveness of its disclosure controls and procedures and internal

control over financial reporting, the

Company has

expended, and

anticipate that

it will continue

to expend,

significant resources,

including accounting-related

costs and significant management oversight.

The Company

has identified certain

material weaknesses in

its internal

controls, as more

fully explained in

its management’s

discussion and

analysis for

the year ended

December 31,

2022, under

“Disclosure

Controls and

Procedures”.

Additional

weaknesses in

the Company’s

disclosure controls

and internal

control over

financial reporting

may also

be discovered

in

the future.

Any failure

to

develop

or maintain

effective

controls

or any

difficulties

encountered

in their

implementation

or

improvement could harm the Company’s results of operations or cause

the Company to fail to meet its reporting

obligations

and may result in

a restatement of the Company’s consolidated financial

statements for prior periods. Any

failure to improve

and maintain effective

internal control over

financial reporting also

could adversely affect

the results of

periodic management

evaluations and annual independent registered public accounting firm attestation reports regarding

the effectiveness of the

Company’s

internal control

over financial

reporting that

the Company

will eventually

be required

to include

in its

periodic

reports

that

will

be

filed

with

the

CSA.

Ineffective

disclosure

controls

and

procedures

and

internal

control

over

financial

reporting could

also cause

investors to

lose confidence

in the

Company’s reported

financial and

other information,

which

could have a negative effect

on the trading price of the

Common Shares. In addition, if

the Company is unable to

continue

to meet these requirements, it may not be able to remain

listed on the TSX and/or NASDAQ.

Influence of the Significant Shareholders

To the Company’s

knowledge, no shareholder beneficially owns, or controls or directs, directly or indirectly, more than 10%

of the voting rights attached to the Company’s

outstanding voting securities, except for

Mr. Photis Peter

Pascali, President

and

Chief

Executive

Officer

of

the

Company,

who

holds

or

controls,

directly

or

indirectly,

80,925,698

Common

Shares,

representing in

aggregate 45.32

%

of the

total voting

rights attached

to the

outstanding Common

Shares, and

2,500,000

share purchase warrants

and options

to acquire an

additional 6,770,000

Common Shares

(increasing the

total number

of

Common Shares held or controlled, directly or

indirectly, by him to 87,695,698 Common Shares, or 47.31%

or the Common

Shares, on

a fully

diluted basis).

In addition,

from time

to time,

the Company

may have

other shareholders

who have

the

ability to

exercise significant

influence over

matters submitted

to the

shareholders of

the Company

for approval,

whether

subject to approval by a majority of the shareholders of

the Company or subject to a class vote or special resolution.

Limited Control Over the Company’s Operations

Holders

of

the

Common

Shares

have

limited

control

over

changes

in

the

Company’s

policies

and

operations,

which

increases

the

uncertainty

and

risks

of

an

investment

in

the

Company.

The

Board

determines

major

policies,

including

policies regarding

financing, growth,

debt capitalization and

any future

dividends to

shareholders of

the Company. Generally,

the Board may amend or revise these and other policies without a vote of the holders

of the Common Shares. The Board’s

broad

discretion

in

setting

policies

and

the

limited

ability

of

holders

of

the

Common

Shares

to

exert

control

over

those

policies increases the uncertainty and risks of an investment

in the Company.

Change in Tax Laws

New income, sales, use or other

tax laws, statutes, rules, regulations

or ordinances could be enacted at

any time. Further,

existing tax laws, statutes, rules, regulations or ordinances could be

interpreted, changed, modified or applied adversely to

the Company. These enactments and events could require the Company to pay additional tax amounts on a prospective or

retroactive

basis,

thereby

substantially

increasing

the

amount

of

taxes

the

Company

is

liable

to

pay

in

the

relevant

tax

jurisdictions. Accordingly,

these events could decrease the capital

that the Company has available to operate

its business.

Any or all of these events could harm the business and

financial performance of the Company.

Forward-Looking Information

The

forward-looking

information

included

in

this

MD&A

relating

to,

among

other

things,

the

Company’s

future

results,

performance, achievements, prospects, targets, intentions or opportunities

or the markets in which

it operates and the

other

statements listed

are based

on opinions,

assumptions and

estimates made

by the

Company’s management

in light

of its

experience and

perception of

historical trends,

current conditions and

expected future developments,

as well

as other

factors

that the Company believes are appropriate and reasonable in the circumstances. However, there can be no assurance that

such estimates and assumptions will

prove to be correct. The Company’s

actual results in the future may

vary significantly

from the historical and estimated results and those variations may

be material. The Company makes no representation that

its actual results in the future will be the same, in whole or

in part, as those included in this MD&A.

Credit Facilities

The Company’s

credit facilities and

financing agreements

mature on various

dates. There

can be no

assurance that such

credit

facilities

or

financing

agreements

will

be

renewed

or

refinanced,

or

if

renewed

or

refinanced,

that

the

renewal

or

refinancing will

occur on

equally favourable

terms to

the Company.

The Company

’s ability

to continue

operating may

be

adversely

affected

if

the

Company

is

not

able

to

renew

its

credit

facilities

or

arrange

refinancing,

or

if

such

renewal

or

refinancing, as the case may

be, occurs on terms

materially less favorable to the

Company than at present. The

Company’s

current credit facilities and financing agreements have no imposed financial covenants and obligations on the Company.

In

the event

of the

contrary,

there is

a risk

that such

loans

may go

into default

if there

is a

breach in

complying

with

such

covenants and obligations, which could result in the lenders realizing on

their security and causing our shareholders to lose

some or all of their investment.

Risks Related to the Company’s Securities

Potential Volatility of Common Share

Price

The market

price of

the Common

Shares could

be subject

to significant

fluctuations. Some

of the

factors that

may cause

the market price of the Common Shares to fluctuate include:

(i)

the

public’s

reaction

to

the

Company’s

press

releases,

announcements

and

filings

with

regulatory

authorities and those of its competitors;

Management’s Discussion and Analysis

(ii)

fluctuations in broader stock market prices and volumes;

(iii)

changes in market valuations of similar companies;

(iv)

investor perception of the Company,

its prospects or the industry in general;

(v)

additions or departures of key personnel;

(vi)

commencement of or involvement in litigation;

(vii)

announcements

by

the

Company

or

its

competitors

of

strategic

alliances,

significant

contracts,

new

technologies, acquisitions, commercial relationships, joint

ventures or capital commitments;

(viii)

variations in the Company’s quarterly results of operations

or cash flows or those of other comparable

companies;

(ix)

revenues and

operating results

failing to

meet the

expectations of

securities analysts

or investors

in

particular quarter;

(x)

changes in the Company’s pricing policies or the pricing

policies of its competitors;

(xi)

future issuances and sales of Common Shares;

(xii)

sales of Common Shares by insiders of the Company;

(xiii)

third party disclosure of significant short positions;

(xiv)

demand for and trading volume of Common Shares;

(xv)

changes

in

securities

analysts’

recommendations

and

their

estimates

of

the

Company’s

financial

performance;

(xvi)

short-term

fluctuation

in

stock

price

caused

by

changes

in

general

conditions

in

the

domestic

and

worldwide economies or financial markets; and

(xvii)

the other risk factors described under this heading of the MD&A.

The realization

of any

of these

risks and

other factors

beyond the Company

’s control

could cause

the market

price of the

Common Shares to decline significantly.

In addition, broad

market and industry

factors may harm

the market price

of the Common

Shares. Hence, the

price of the

Common Shares

could fluctuate based

upon factors

that have

little or

nothing to

do with

the Company, and these

fluctuations

could materially reduce the price

of the Common Shares

regardless of the Company’s

operating performance. In the past,

following a significant

decline in the

market price of

a company’s

securities, there

have been instances

of securities class

action litigation having been instituted against that

company. If

the Company were involved in any similar

litigation, it could

incur substantial

costs, management’s attention

and resources could

be diverted

and it

could harm the

Company’s business,

operating results and financial condition.

Market Liquidity

The

market

price

for

the

Common

Shares

could

be

subject

to

wide

fluctuations.

Factors

such

as

the

announcement

of

significant

contracts,

technological

innovations,

new

commercial

products,

patents,

a

change

in

regulations,

quarterly

financial results,

future sales

of Common

Shares by

the Company

or current

shareholders, and

many other

factors could

have considerable

repercussions on

the price

of the

Common Shares.

In addition,

the financial

markets may

experience

significant price

and value

fluctuations that

affect the

market prices

of equity

securities of

companies that

sometimes are

unrelated

to

the

operating

performance

of

these

companies.

Broad

market

fluctuations,

as

well

as

economic

conditions

generally may adversely affect the market price of

the Common Shares.

Dividends to Shareholders

The Company does not anticipate

paying cash dividends on the

Common Shares in the foreseeable

future. The Company

currently intends

to retain

all future

earnings to

fund the

development and

growth of

its business.

Any payment

of future

dividends will be at

the discretion of the

directors and will depend

on, among other

things, the Company’s earnings, financial

condition,

capital

requirements,

level

of

indebtedness,

statutory

and

contractual

restrictions

applying

to

the

payment

of

dividends, and other considerations that the directors

deems relevant.

Impact of Future Sales by Existing Shareholders

If the Company’s shareholders sell substantial amounts of

the Common Shares in the public market,

the market price of the

Common Shares could decrease. The

perception among investors that these

sales will occur could also

produce this effect.

All

currently

outstanding

Common

Shares

other

than

those

subject

to

lock-up

agreements

executed

by

certain

existing

shareholders will, subject to applicable securities laws,

generally be immediately available for resale in the public

markets.

Subject to compliance

with applicable

securities laws,

the Company’s

officers, directors

and their affiliates

may sell some

or all of their Common

Shares in the future. No prediction can

be made as to the

effect, if any, such future sales of Common

Shares will

have on

the market

price of

the Common

Shares prevailing

from time

to time.

However,

the future

sale of

a

substantial number of Common Shares by the Company’s

officers, directors and their affiliates, or the

perception that such

sales could occur, could materially

adversely affect prevailing market prices for the

Common Shares.

Additional Common Shares issuable upon the exercise of stock options may also be available for sale in the public market,

which

may

also

cause

the

market

price

of

the

Common

Shares

to

fall.

Accordingly,

if

substantial

amounts

of

Common

Shares are sold in the public market, the market price could

fall.

Working Capital and Future Issuances

The

Company

may

issue

additional

Common

Shares

in

the

future

which

may

dilute

a

shareholder’s

holdings

in

the

Company. The Articles

permit the issuance of an unlimited number of Common Shares,

and shareholders of the Company

will have no pre-emptive

rights in connection with

any further issuances The

directors of the Company

have the discretion

to

determine

the

provisions

attaching

to

the

Common

Shares

and

the

price

and

the

terms

of

issue

of

further

Common

Shares.

Additional equity

financing may

be dilutive

to holders

of Common

Shares. Debt

financing may

involve restrictions

on the

Company’s financing and operating activities. Debt financing

may be convertible into other

securities of the Company which

may result

in immediate

or resulting

dilution. In

either case,

additional financing

may not

be available

to the

Company on

acceptable

terms

or at

all.

If the

Company

is unable

to

raise

additional

funds

as needed,

the

scope

of its

operations

or

growth may

be reduced

and, as

a result,

the Company

may be

unable to

fulfill

its long-term

goals. In

this case,

investors

may lose

all or part

of their

investment. Any

default under

such debt

instruments could

have a

material adverse

effect on

the Company,

its business or the results of operations.

Securities or Industry Analysts

The trading

market

for Common

Shares

could

be

influenced

by the

research

and

reports

that

industry

and/or

securities

analysts may publish about the Company, its business, the market or competitors. If any of the analysts who may cover the

Company’s business change

their recommendation regarding

the Common Shares

adversely,

or provide more favourable

relative

recommendations

about

its

competitors,

the

share

price

would

likely

decline.

If

any

analyst

who

may

cover

the

Company’s business

were to

cease coverage

or fail to

regularly publish

reports on

the Company,

it could

lose visibility

in

the financial markets, which in turn could cause the share price

or trading volume to decline.

Risks Related to the Company’s Status as a Foreign

Private Issuer

Information Publicly Available to the Company’s U.S.

shareholders

The Company is

a foreign private

issuer under applicable

U.S. federal securities

laws. As a result,

the Company does

not

file the same reports that a U.S. domestic

issuer would file with the U.S. Securities and Exchange Commission (the

“SEC”),

although the Company is required to file with or furnish to the SEC the continuous disclosure documents that the Company

PyroGenesis Canada Inc.

Management’s Discussion and Analysis

For the years ended December 31, 2022, and

2021

33

| Page

is required to file in Canada under Canadian Securities Laws, in certain

respects the reporting obligations are less detailed

and

less

frequent

than

those

of

U.S.

domestic

reporting

companies.

In

addition,

the

Company’s

officers,

directors

and

principal shareholders

are exempt

from the

reporting and

short-swing profit

recovery provisions

of Section 16

of the

U.S.

Exchange Act.

Therefore, the

Company’s shareholders

may not know

on as

timely a

basis when

the Company’s

officers,

directors and

principal shareholders

purchase or

sell

Common Shares

as the

reporting

periods under

the corresponding

Canadian insider reporting requirements are longer.

As a foreign

private issuer,

the Company is

exempt from

the rules and

regulations under

the Exchange

Act related to

the

furnishing and content of proxy statements. The Company is also exempt from Regulation FD, which prohibits issuers from

making

selective

disclosures

of

material

non-public

information.

While

the

Company

complies

with

the

corresponding

requirements relating to proxy

statements and disclosure of

material non-public information under

Canadian securities laws,

these requirements

differ from

those under

the Exchange

Act and

Regulation FD

and shareholders

should not

expect to

receive the

same information

at the

same time

as such

information is

provided by

U.S. domestic

companies. In

addition,

the Company may not be required under the Exchange Act to file annual

and quarterly reports with the SEC as promptly as

U.S. domestic companies whose securities are registered

under the Exchange Act.

In

addition,

as

a

foreign

private

issuer,

the

Company

has

the

option

to

follow

certain

Canadian

corporate

governance

practices, except

to the

extent that

such laws

would be

contrary to

U.S. securities

laws, and

provided that

the Company

discloses the requirements it is not following and describe the Canadian practices it follows instead. The Company plans to

rely

on

this

exemption.

As

a

result,

the

Company’s

shareholders

may

not

have

the

same

protections

afforded

to

shareholders of U.S. domestic companies that are subject

to all U.S. corporate governance requirements.

Loss of Foreign Private Issuer Status in the Future

In

order

to

maintain

its

status

as

a

foreign

private

issuer,

a

majority

of

the

Company’s

Common

Shares

must

be

either

directly

or

indirectly

owned

by

non-residents

of

the

U.S.

unless

the

Company

also

satisfies

one

of

the

additional

requirements necessary

to preserve

this status.

The Company

may in

the future

lose its

foreign private

issuer status

if a

majority of the

Common Shares

are held

in the United

States and

the Company

fails to meet

the additional

requirements

necessary to avoid

loss of foreign

private issuer

status. The

regulatory and compliance

costs to the

Company under

U.S.

federal

securities

laws

as

a

U.S.

domestic

issuer

may

be

significantly

more

than

the

costs

the

Company

incurs

as

a

Canadian foreign private

issuer eligible to

use the multi-jurisdictional

disclosure system ("MJDS").

If the Company

is not a

foreign private

issuer,

it would

not be eligible

to use

the MJDS

or other

foreign issuer

forms and

would be

required to

file

periodic

and

current

reports

and

registration

statements

on

U.S.

domestic

issuer

forms

with

the

SEC,

which

are

more

detailed and extensive than the forms available

to a foreign private issuer.

In addition, the Company may lose the

ability to

rely upon exemptions from NASDAQ corporate governance

requirements that are available to foreign private

issuers.

Inability for U.S. Investors to Enforce Certain Judgments

The Company is a corporation existing

under the Canada Business Corporations Act. A number of

the Company’s directors

and officers are

residents of Canada,

and substantially all

of the Company’s

assets are located

outside the United

States.

As a result, it may be difficult to effect service within the United States upon the Company or upon its directors and officers.

Execution by

United States

courts of

any judgment

obtained

against the

Company

or any

of the

Company’s

directors or

officers

in

United

States

courts

may

be

limited

to

the

assets

of

such

companies

or

such

persons,

as

the

case

may

be,

located in the United States. It may also be difficult for holders of securities who reside in the United States to realize in the

United

States

upon

judgments

of

courts

of

the

United

States

predicated

upon

civil

liability

and

the

civil

liability

of

the

Company’s directors and

executive officers under

the United States

federal securities laws.

The Company has

been advised

that a

judgment of

a U.S.

court predicated

solely upon

civil liability

under U.S.

federal securities

laws or

the securities

or

“blue sky”

laws of

any state

within the

United States,

would likely

be enforceable

in Canada

if the

United States

court in

which the judgment was obtained has a basis

for jurisdiction in the matter that would be recognized

by a Canadian court for

the same purposes. However, there may be doubt

as to the enforceability in Canada

against these non-U.S. entities or their

controlling persons,

directors

and officers

who are

not residents

of the

United States,

in original

actions or

in actions

for

enforcement of judgments of courts of the United States, of liabilities predicated solely upon U.S. federal or state securities

laws.

Risks Relating to the Company’s Status as

an "Emerging Growth Company" Under U.S. Securities

Laws

The Company is an "emerging growth company" as defined in section 3(a) of the Exchange Act (as amended by the JOBS

Act, enacted on April 5, 2012),

and the Company will

continue to qualify as an

emerging growth company until

the earliest

to

occur

of:

(a) the

last

day

of

the

fiscal year

during

which

the

Company

has

total

annual

gross

revenues

of

US$1,070,000,000 (as

such amount

is indexed

for inflation

every five

years by

the SEC)

or more;

(b) the last

day of

the

fiscal year

of the

Company

following the

fifth anniversary

of the

date of

the

first sale

of common

equity securities

of the

Company

pursuant

to

an

effective

registration

statement

under

the

United

States

Securities

Act

of

1933,

as

amended;

(c) the date on which the

Company has, during the previous three year period, issued

more than US$1,000,000,000 in non-

convertible debt;

and (d) the date

on which

the Company is

deemed to

be a

"large accelerated filer",

as defined

in Rule 12b-2

under the Exchange Act. The Company will qualify as a large, accelerated filer (and would

cease to be an emerging growth

company) at

such time

when on

the last

business day

of its

second fiscal

quarter of

such year

the aggregate

worldwide

market value of its common equity held by non-affiliates

will be US$700,000,000 or more.

For so long as the Company

remains an emerging growth company,

it is permitted to and intends

to rely upon exemptions

from certain disclosure

requirements that are applicable

to other public

companies that are not

emerging growth companies.

These exemptions include

not being

required to comply

with the auditor

attestation requirements of

Section 404 of the

JOBS

Act.

The

Company

takes

advantage

of

some,

but

not

all,

of

the

available

exemptions

available

to

emerging

growth

companies.

The

Company

cannot

predict

whether

investors

will

find

the

Common

Shares

less

attractive

because

the

Company relies

upon certain

of these

exemptions. If

some investors

find the

Common Shares

less attractive

as a

result,

there may be a less active trading market

for the Common Shares and the Common

Share price may be more volatile. On

the other

hand, if

the Company

no longer

qualifies as

an emerging

growth company,

the Company

would be

required to

divert additional management time

and attention from the Company

’s development and other

business activities and incur

increased legal and financial costs to comply with the additional associated

reporting requirements, which could negatively

impact the Company’s business, financial condition

and results of operations.

OUTLOOK

In 2022, PyroGenesis

remained focused

on driving

its major

lines of business

toward widespread

acceptance, moving

its

newer innovations closer to commercialization, finding efficiencies,

and maintaining margin – all while providing the type of

superior service and solutions that have endeared the

Company to large global public, private, and government

partners.

The information below represents important highlights

from the past year, followed

by an outline of the company’s strategy

and outlook for 2023.

Key Strategic Actions

Major Deliverables

Titanium Powder Commercial Orders:

During 2022, the Company announced

it had received and completed its

first two commercial orders for

Titanium powders using its NexGen™ plasma atomization process.

The first, for 100

kg, was

under

its mutually

exclusive

partnership

agreement

with

Aubert

& Duval,

a major

supplier of

metal

powders

for additive

manufacturing serving the

Aerospace, Energy,

Transport, Medical,

Defense, and Automotive

sectors; the second, also

for

100 kg, was to a confidential customer.

Iron

Ore

Pelletization

Torches:

During

2022,

the

Company

continued

to

progress

its

major

initiative to

supply

electric

plasma

torch

systems

to

large

iron

ore

companies

for

first-ever

trials

in

this

important

upstream

part

of

the

steelmaking process.

In July

2022, the

first plasma

system plus

required components

was completed

and delivered

to a

client. Subsequent to year

-end 2022, in January

2023, four electric plasma

torch systems plus

required components were

delivered to

a second

client. These

clients are

two of

the largest

iron ore

companies

in the

world and

each has

made a

significant

financial

and

logistical

commitment

over

the

past two

years

to test

plasma

as a

possible

replacement

for the

diesel and/or natural gas furnace

burners needed for iron

ore pellet baking. Live

onsite trials and testing

will be conducted

per client-defined scheduling,

based on the Client’s

own resourcing and

logistical decisions of which

the Company has no

input.

Metal Powder

Aerospace Client

Qualification:

In September

2022, the

Company announced

it had

completed

the

in-house

quality

audit

of

its

NexGen™

metal

powder

production

facility

and

process,

which

it

also

later

passed

subsequent to year-end

2022, by a

large global aerospace

client. The in-house

audit was part

of an almost

two year long

process of qualification

by the client,

towards an end-goal

of being a

certified supplier of

titanium metal powders to

the client,

its suppliers, and service centers. With the audit completed,

the last step is a testing of the Company’s

powders, which will

be conducted per client-defined scheduling.

Innovations

Aluminum Scrap

Remelting:

in May

2022, the

Company announced

it had

undertaken a

joint evaluation

with a

major manufacturer to

test PyroGenesis’ zero-emission

plasma torches in

the Client’s aluminum

scrap remelting and

holding

furnaces. This was one

of several secondary or

tertiary aluminum producers

who are investigating the

Company’s electric

plasma torches to replace fossil fuels in recycled aluminum

production, holding tank heating, or cast houses.

Carbon-anode baking:

The Company

announced in

June 2022 it

had undertaken

a joint initiative

with a premier

applied engineering and process optimization

firm in the global aluminum industry,

focused on utilizing PyroGenesis’ zero-

emission

plasma

torches

in

carbon

anode

baking

a

vital

upstream

step

in

the

aluminum

production

process.

Carbon

anodes, which

are used

as an

electrical conductor

during the

aluminum smelting

process but

constantly

consumed,

are

traditionally produced

using natural

gas baking;

reducing fossil

fuel use

while optimizing

the anode

baking process

is an

objective in the industry for manufacturers of high-grade

anodes.

Spent-pot linings:

The Company continues

to progress

the previously announced

initiative to develop

a solution

to recover residues of aluminum pot linings, in conjunction

with project partner Aluminerie Alouette (co-owned

by Rio Tinto

and Norsk

Hydro), the

largest primary

aluminum smelter

in the

Americas. The

solution under

development is

intended to

safely

recover

valuable

metals

and

various

compounds

from

the

heavily

contaminated

carbon-lined

cells

or

“pots”

from

inside a smelter, which degrade over time

and must be removed

and safely disposed. The project

evolved throughout 2022,

with

additional

technology

benchmarks

being

met,

and

with

the

Company

and

Aluminerie

Alouette

deepening

their

relationship with a further commitment.

Magnesium

Recovery and

Valourization:

in September

2022, the

Company

announced it

was

selected

by an

international

producer

of magnesium

metal to

develop

two processes:

a method

to clean

and decontaminate

particulate

matter produced

during primary

magnesium production,

and to

process the

metal waste

stream known

as dross,

for the

purpose of recovering valuable

metal. Dross recovery is

not widespread in the

magnesium industry,

due to the complexity

of the process and the

inherent challenges of working with magnesium – a

very combustible and volatile metal that is highly

reactive

to

oxygen.

With

PyroGenesis’

expertise

in

recovering

high-value

metal

from

dross

in

other

industries

(such

as

aluminum), the Company believes it has the solution to the specific challenges posed by magnesium, potentially opening a

large opportunity for growth, while decreasing the Client’s

environmental impact.

Turquoise

Hydrogen

Production:

The

Company

continues

to

progress

the

previously

announced

initiative

to

produce

an

environmentally

friendly

hydrogen.

In

November

2022,

the

Company

successfully

produced

hydrogen

from

methane using

this ZCE

hydrogen production

technology

which, because

it uses

electricity in

the form

of plasma,

rather

than combustion

of fossil

fuels, is

typically referred

to as

“Turquoise

Hydrogen”. A

solid carbon

byproduct that

has many

industrial applications (including the production of

car tires, coatings, plastics, and

batteries), and is considered an

essential

raw material, is also produced through the process.

Operational

European

Metal

Powders

Production:

Throughout

2022,

the

Company

continued

to

evolve

its

strategy,

first

announced in

July 2022,

for European

market expansion

for its

titanium metal

powder

line of

business. With

the goal

to

eventually build

and operate

a metal

powder production

facility in

Europe. Subsequent

to year-end

2022, in

Q1 2023

the

Company announced

expansion

of its

strategy

team,

with the

hiring of

a key

Europe-based

executive with

a long

track-

record across sales,

marketing, and business

process in the

metals industry, particularly the aerospace,

space, and defense

markets.

Quality Management Process Certification:

In November 2022, the Company passed its annual quality audit for

two key international standards: ISO 9001:2015, and AS9100D, the latter being a quality management designation specific

to the

aerospace

industry.

The audits

encompassed

all of

PyroGenesis’

facilities

for the

purpose of

meeting

compliance

with

the

existing

quality

management

designations.

Additionally,

as

a

result

of

this

audit,

the

Company’s

newest

facility

located at

9371 Wanklyn

St. in

LaSalle, Quebec,

was officially

added to

the ISO

9001:2015 certification.

Separately,

the

Company continues

its path to

become ISO 13485:2016

certified, a Quality

Management System

designation required by

most manufacturers within the medical devices and related services

industry.

Private Placement:

In October

2022, the

Company announced the

completion of a

non-brokered private placement

consisting of the issuance and sale of 1,014,600 units of the Corporation

at a price of $1.30 per Unit, for gross proceeds of

$1,318,980 to the Company. The closing price of the common shares of the

Company on October 18, 2022, the last

trading

day prior to the closing of the Private Placement, was $1.17. Each Unit

consists of one common share of the Company and

one Common Share purchase warrant. Each Warrant entitles the holder thereof to purchase one Common Share at a price

of $1.75 until October 19,

  1. The Common Shares

and Warrants issued

in connection with the Private

Placement, and

the Common

Shares underlying

the Warrants,

are subject

to a statutory

hold period

of four months

and one

day from the

date of closing, in accordance with applicable securities

legislation.

Outlook

Consistent with the Company’s past

practice, and in view of

the early stage of

market adoption of our

core lines of business,

we are not providing specific revenue or net income (loss)

guidance for 2023.

In 2023,

we continue

our plan

to increase

sales, marketing,

and R&D

efforts in-line

– and

in some

cases ahead

of –

the

growth curve for industrial change related to greenhouse gas reduction efforts. This includes expanded technology offering

and capabilities across the industrial value chain, using

an updated strategy that sees the Company bundle

its solution-set

into verticals that represent key economic drivers for

heavy industry.

Overall Strategy

PyroGenesis’

provides

technology

solutions

to

heavy

industry

that

leverage

off

the

Company’s

proprietary

position

and

expertise

in

ultra-high

temperature

processes.

The

Company

has

evolved

from

its

early

roots

of

being

a

speciality-

engineering firm to being a

provider of a robust technology

eco-system for heavy industry

that helps address key

strategic

goals.

Aligning Business Lines to Economic Drivers

As interest in

the Company’s

products has increased,

and the variety

of uses for

its core technologies

has expanded,

the

Company

has

evolved

its

strategy

to

concentrate

its

solution

set

under

three

categories.

These

categories

represent

economic drivers that are key to global heavy industry:

1.

Energy Transition & Emission

Reduction:

fuel switching,

utilizing the

Company’s electric-powered

plasma torches

and biogas

upgrading technology

to help

heavy industry reduce fossil fuel use and greenhouse gas

emissions.

2.

Commodity Security & Optimization:

recovery of viable

metals, and optimization of

production to increase output,

to maximize raw materials

and improve

availability of critical minerals.

3.

Waste Remediation:

safe

destruction

of

hazardous

materials,

and

the

recovery

and

valorization

of

underlying

substances

such

as

chemicals and minerals.

| Page

Within each

category the

Company offers

several solutions

at different

stages leading

up to

commercialization,

including

the partial list in the diagram below:

The Company’s

believes its

strategy to

be timely,

as multiple

heavy industries

are committing

to major

carbon and

waste

reduction

targets

at

the

same

time

as

many

governments

are

increasingly

funding

environmental

technologies

and

infrastructure

projects

– all

while both

are making

efforts

to ensure

the

availability

of critical

minerals

during

the coming

decades of increased output demand.

While there can

be no guarantee,

the Company believes

this evolution of

its strategy beyond

a greenhouse

gas emission

reduction emphasis, to an

expanded focus that encapsulates

the key verticals listed above,

both improves the Company’s

chances for success while also providing a clearer

picture of how the Company’s wide array

of offerings work in tandem to

support heavy industry goals.

PyroGenesis’ market

opportunity remains

large, as

major industries

such as

aluminum, steelmaking,

manufacturing, and

government require factory-ready, technology-based solutions

to help steer

through the paradoxical

landscape of

increasing

demand and tightening regulations and material availability.

As more of the Company’s

offerings reach full commercialization,

PyroGenesis will remain focused on

attracting influential

customers in broad markets and ensuring that operating

expenses are controlled to achieve profitable growth.

Report of Independent Registered Public Accounting Firm

To

the Shareholders and Directors of PyroGenesis Canada Inc.

Opinion on the consolidated financial statements

We have

audited the

accompanying consolidated

statements of

financial position

of PyroGenesis

Canada Inc.

(the "Company")

as of

December 31,

2022 and

2021, the

related consolidated

statements of

comprehensive loss,

changes in

shareholders’ equity

and cash

flows for the years then ended,

and the related notes (collectively referred

to as the "consolidated financial statements"). In

our opinion,

the consolidated

financial statements present

fairly,

in all

material respects,

the financial position

of the

Company as

of December

31,

2022 and

2021, and

the results

of its

operations and

its cash

flows for

the years

then ended

in conformity

with International

Financial

Reporting Standards as issued by the International Accounting Standards Board.

Going concern

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as

a going concern.

As discussed

in Note

2 to

the consolidated

financial statements,

the Company

has incurred

operating losses

and negative

cash flows

from operations and, as a result, has an accumulated deficit as of

December 31, 2022. These conditions, along with other matters as set

forth in

Note 2,

indicate the existence

of a material

uncertainty that

may cast significant

doubt about

the Company’s

ability to continue

operating as a

going concern. Management's

plans in regard

to these matters

are also described

in Note 2.

The consolidated financial

statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for opinion

These consolidated financial statements are

the responsibility of the Company’s

management. Our responsibility is to

express an opinion

on the

Company's consolidated

financial statements

based on

our audits.

We

are a

public accounting

firm registered

with the

Public

Company Accounting

Oversight Board (United

States) ("PCAOB") and

are required to

be independent with

respect to the

Company in

accordance with the

U.S. federal securities

laws and the

applicable rules and

regulations of the

Securities and Exchange

Commission

and the PCAOB.

We conducted our

audits in accordance with

the standards of the

PCAOB. Those standards require

that we plan and

perform the audit

to obtain reasonable

assurance about whether

the consolidated financial

statements are free

of material misstatement,

whether due to

error

or

fraud.

The

Company is

not

required

to

have,

nor

were

we engaged

to

perform, an

audit

of

its internal

control

over

financial

reporting. As

part of

our audits,

we are

required to

obtain an

understanding of

internal control

over financial

reporting but

not for

the

purpose of expressing an opinion

on the effectiveness of the

Company's internal control over financial

reporting. Accordingly, we express

no such opinion.

Our audits included performing

procedures to assess the

risks of material misstatement

of the consolidated financial

statements, whether

due

to

error

or

fraud,

and performing

procedures

that

respond to

those

risks. Such

procedures included

examining,

on

a

test basis,

evidence

regarding

the

amounts

and

disclosures

in

the

consolidated

financial

statements.

Our

audits

also

included

evaluating

the

accounting

principles

used

and

significant

estimates

made

by

management,

as

well

as

evaluating

the

overall

presentation

of

the

consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

We have served as the Company’s auditor since 2021.

1.

Nature of operations

PyroGenesis Canada Inc.

(“PyroGenesis”) and

its subsidiaries

(collectively,

the “Company”),

incorporated under

the laws

of the Canada

Business Corporations

Act, was formed

on July 11,

2011.

The Company

owns patents

of advanced waste

treatment systems technology and designs,

develops, manufactures, and commercialises advanced plasma processes and

sustainable solutions to reduce greenhouse gases. The Company is domiciled at 1744 William Street, Suite 200, Montreal,

Quebec. The Company

is publicly traded

on the TSX

Exchange under

the Symbol “PYR”,

on NASDAQ

in the USA

under

the symbol “PYR” and on the Frankfurt Stock Exchange (FSX)

under the symbol “8PY”.

2.

Going concern

These

consolidated

financial

statements

have

been

prepared

on

the

going

concern

basis,

which

presumes

that

the

Company will be

able to continue

its operations

for the foreseeable

and will be

able to realize

its assets and

discharge its

liabilities in the normal course of business for the foreseeable

future.

The Company is

subject to certain

risks and uncertainty

associated with the

achievement of profitable

operations such

as

the successful signing and delivery of contracts and access

to adequate financing.

The Company

has incurred,

in the

last years,

operating losses

and negative

cash flows

from operations,

and as

a result,

the Company has

an accumulated deficit of

$

93,384,858

as at December

31, 2022 ($

61,217,831

as at December

31, 2021).

Furthermore, there have been unexpected delays in the collection of certain accounts receivable from contracts closed in a

prior year. This has

resulted in a

shortfall in cash

flows from operating

activities that would

be used in

funding the Company’s

operations.

As

at

December

31,

2022,

the

Company

has

working

capital

of

$

1,650,709

($

14,006,785

as

at

December

31,

2021)

including cash and

cash equivalents

of $

3,445,649

($

12,202,513

as at December

31, 2021). The

working capital

is net of

an allowance for credit losses amounting to $

5,023,283

($

520,000

as at December 31, 2021) as further described

in notes

9 and 10. The Company’s

business plan is dependent

upon the successful completion

of contracts and also

the receipt of

payments from certain contracts

closed in a prior year and expects

these payments to be made

during fiscal 2023, as well

as

the

achievement

of

profitable

operations

through

the

signing,

completion

and

delivery

of

additional

contracts

or

a

reduction in certain operating expenses. In the absence of this, the Company is dependent upon raising additional funds to

finance operations within

and beyond the next

twelve months. The Company

has been successful

in securing financing in

the past

and has

relied upon

external financing

to fund

its operations,

primarily

through the

issuance of

equity,

debt and

convertible debentures.

The Company

completed a

private placement

in October

2022 for

an amount

of $

1,318,980

and

also

completed

another

private

placement

in

March

2023

for

$

5,000,000

(see

note

33).

While

the

Company

has

been

successful in securing

financing, raising

additional funds

is dependent

on a number

of factors, some

of which

are outside

the Company’s

control, and therefore

there is no

assurance that

it will be

able to do

so in the

future or that

these sources

will

be

available

to

the

Company

or

that

they

will

be

available

on

terms

which

are

acceptable

to

the

Company.

These

conditions indicate

the existence

of a

material uncertainty

that may

cast significant

doubt about

the Company’s

ability to

continue operating as a going concern.

The consolidated financial

statements have

been prepared on

a going concern

basis and do

not include

any adjustments

to the amounts and to classifications of the assets and liabilities that might be necessary should the Company be unable to

achieve its plan and continue in business. If the going concern assumption were not appropriate, adjustments,

which could

be material, would be necessary to the carrying value of assets and liabilities, the reported expenses, and the classification

of items on the consolidated statement of financial position.

3.

Basis of preparation

(a)

Statement of compliance

These financial statements have been prepared

in accordance with International Financial Reporting Standards (“IFRS”) as

issued by

the International Accounting

Standards Board (“IASB”).

These financial statements

were approved and

authorized

for issuance by the Board of Directors on March 30, 2023.

PyroGenesis Canada Inc.

Notes to the Consolidated Financial Statements

For the years ended December 31, 2022 and 2021

(In Canadian dollars)

(b)

Functional and presentation currency

These consolidated financial

statements are presented

in Canadian dollars,

which is the

functional currency of

PyroGenesis,

Drosrite International

LLC and

Pyro Green-Gas

Inc. The

functional currency

of Airscience

Italia SRL

is the

Euro whereas

the functional currency of Airscience Technologies

Private Limited is the Indian

rupee.

(c)

Basis of measurement

These financial statements have been prepared on the historical

cost basis except for:

(i)

strategic investments which are accounted for at fair value,

(ii)

share-based payment arrangements, which are measured at

fair value on the grant date pursuant to IFRS

2, Share-based Payment; and

(iii)

lease liabilities, which are initially measured at the present

value of minimum lease payments

(d)

Basis of consolidation

For financial reporting purposes, subsidiaries are defined as entities controlled by the Company.

The Company controls an

entity when it

has power over

the investee; it

is exposed to,

or has rights to,

variable returns from

its involvement with

the

entity; and it has the ability to affect those returns through

its power over the entity.

In instances

where the

Company does

not hold

a majority

of the

voting rights,

further analysis

is performed

to determine

whether or not

the Company has

control of the

entity. The Company is deemed to

have control when, according

to the terms

of the shareholder’s and/or other agreements, it makes most of

the decisions affecting relevant activities.

These consolidated

financial

statements

include the

accounts

of PyroGenesis

and

its subsidiaries,

Drosrite

International

LLC and Pyro Green-Gas Inc. and its subsidiaries. Drosrite International LLC is owned by a member of the Company’s key

management personnel and close member of

the Chief Executive Officer (“CEO”)

and controlling shareholder’s family and

is deemed to be controlled by the Company.

Pyro Green-Gas Inc. and its subsidiaries Airscience Italia SRL and Airscience

Technologies Private Limited were acquired

by the

Company on August

11, 2021 (see note

6). All

transactions and balances

between the Company and its subsidiaries have been eliminated

upon consolidation.

The

accounting

policies

set

out

below

have

been

applied

consistently

in

the

preparation

of

the

consolidated

financial

statements of all years

presented. Finance costs

and changes in fair

value of strategic

investments are excluded

from the

loss from operations in the consolidated statements of

comprehensive loss.

4.

Significant accounting policies

(a)

Business combinations

Business combinations are accounted

for using the

acquisition method. Goodwill is

measured as the

excess of the

fair value

of the consideration transferred over the

net recognized amount of the identifiable

assets acquired and liabilities assumed,

all measured at the acquisition date.

The consideration transferred is measured as the net of the fair values of assets transferred,

liabilities assumed, and equity

instruments

issued

by

the

Company

at

the

acquisition

date,

including

any

asset

or

liability

resulting

from

a

contingent

consideration arrangement, in exchange of the acquiree.

The obligation to pay the contingent consideration

is classified as a liability and measured as a financial

instrument or as a

provision. Changes in fair values that qualify as measurement period adjustments of preliminary purchase price allocations

are adjusted in the current period and such changes are

applied on a retroactive basis.

Acquisition costs

that the

Company incurs

in connection

with a

business

combination

are recognized

in profit

or loss

as

incurred, except for costs associated with the issuance

of debt or equity securities.

(b)

Revenue recognition

Revenue from

contracts

is recognized

for each

performance obligation

either over

a period

of time

or at

a point

in time,

depending on which method reflects the transfer of control of the goods and services underlying the particular performance

obligation.

i)

Long-term contracts

Long-term contracts

involve made-to-order

customized equipment

and machines

and are

generally priced

on a

fixed fee

basis.

Under

these

contracts,

the

equipment

or

machines

are

made

to

a

customer’s

specifications

and

if

a

contract

is

terminated by the customer, the Company

is entitled to the greater of the amounts invoiced at the termination

date and the

reimbursement of the costs

incurred to date of

termination, including a reasonable margin.

Agreements that contain multiple

deliverables require the Company to determine whether they contain separately identifiable performance obligations and to

allocate the consideration received to each performance

obligation.

Revenue

relating

to

long-term

contracts

is

recognized

over

time

based

on

the

measure

of

progress

determined

by

the

Company’s efforts or inputs

towards satisfying the performance obligation

relative to the total expected inputs.

The degree

of completion

is assessed

based on

the

proportion

of

total costs

and/or

hours

incurred

to date,

compared

to

total costs

and/or hours anticipated

to provide the

service under the

entire contract,

excluding the effects

of inputs that

do not depict

performance,

e.g.

uninstalled

materials.

For

long-term

contracts

with

uninstalled

materials,

the

Company

adjusts

the

transaction price and

recognizes revenue on

uninstalled materials to the

extent of those

costs incurred, i.e.

at a zero percent

profit margin, when certain conditions are met.

Estimates are required

to determine anticipated

costs and/or hours

on long-term contracts. A

provision is made

for the entire

amount of expected loss, if any,

in the period in which they are first determinable.

Contract modifications are changes in scope and/or price that are approved by the parties to the contract. Approval may

be

written,

oral

or

implied

by

customary

business

practices,

and

are

legally

enforceable.

The

Company

accounts

for

modifications as a separate

contract if the modifications

add distinct goods or

services that are priced

commensurate with

stand-alone

selling

prices

or

if

the

remaining

goods

or

services

are

distinct

from

those

already

transferred,

otherwise

modifications are accounted for as part of the original contract.

Costs and

profits in

excess of

billings on

uncompleted contracts

and trade

receivables are

both rights

to consideration

in

exchange for

goods or

services that

the Company

has transferred

to a

customer,

however the

classification

depends on

whether such right is only

conditional on the passage of time

(trade receivables) or if it is

also conditional on something else

(costs and profits

in excess of

billings on uncompleted contracts),

such as the

satisfaction of further performance

obligations

under the contract. Billings in excess of costs and

profits on uncompleted contracts is the cumulative

amount received and

contractually receivable by the Company that exceeds the right

to consideration resulting from the Company’s performance

under a given contract.

The costs

to obtain

long-term contracts

such as

sale commissions

are recognized

as Contract

assets and

recognized as

selling expenses over time based on degree of completion

of the related contract.

ii)

Sales of goods

Revenue related to sales of goods, which may

include powders and spare parts are measured

based on the consideration

specified in contracts

with customers. The

Company recognizes

revenue at a

point in time

when it transfers

control of the

goods to

the buyer.

This is

generally at

the time

the customer

obtains legal

title to

the product

and when

it is

physically

transferred to the custody transfer point agreed with the customer.

iii)

Sale of intellectual property

Sale of

intellectual property is

recognized at the

date the recipient

obtains control of

the asset. Variable consideration related

to the sale of intellectual property is recognized to the extent that it

is highly probable that a reversal will not occur when the

uncertainty associated with the variable consideration

is subsequently resolved.

(c)

Foreign currency translation

i)

Foreign currency transactions

Revenue and expense transactions in foreign

currencies are translated into the functional

currency of the respective entity

using the

average exchange

rates prevailing

at the

time of

the transaction.

Foreign currency

balances are

translated into

the functional

currency of

the respect

ive entity

at year

end exchange

rates for

monetary items

and at

historical

rates for

non-monetary items. Translation gains

or losses are included in the determination of net loss.

ii)

Foreign operations

The assets and

liabilities of foreign

operations are translated

into Canadian dollars

using exchange rates

prevailing at the

end

of

the

reporting

period.

Revenue

and

expense

items

are

translated

at

the

average

exchange

rates

for

the

period.

Exchange

differences

arising

from

the

translation

process

of

foreign

operations

are

recognized

as

foreign

currency

translation adjustments in other comprehensive income and

accumulated in equity.

(d)

Cash and cash equivalents

Cash and

cash equivalents

are financial

instruments readily

convertible to

a known

amount of

cash and

not subject

to a

significant risk of

changes in fair

value. Cash equivalents

include instruments with

a maturity of

three months or

less from

the date of

acquisition and

instruments with

an original

term longer than

three months if

there is

no significant

penalty for

withdrawal within a three-month period from the date

of acquisition.

(e)

Inventory

Inventory is composed of spare

parts for resale. Inventory

is valued at the

lower of cost and net

realizable value. The

cost

of

inventory

is

based

on

the

first-in,

first-out

principle

and

comprises

all

costs

of

purchases.

Net

realizable

value

is

the

estimated selling price in the ordinary course of business,

less estimated costs of completion and selling costs.

(f)

Income taxes

i)

Current tax

Current tax assets and liabilities for the current and prior years are measured at the amount expected to be recovered from

or paid

to the

taxation authorities.

The tax

rates and

tax laws

used to

compute the

amount are

those that

are enacted

or

substantively enacted by the date of the consolidated statements

of financial position.

iii)

Deferred tax

Deferred tax is provided using the liability method, providing for temporary differences between the tax

bases of assets and

liabilities and their carrying

amounts in the consolidated

financial statements. The

temporary difference

is not provided for

if it arises from the initial recognition

of goodwill or the initial recognition

of an asset or liability in

a transaction other than

a

business combination that at the time of the transaction affects neither accounting

nor taxable profit or loss. The amount of

deferred tax

provided is

based on

the expected

manner of

realization or

settlement of

the carrying

amount of

assets and

liabilities, using tax

rates enacted or

substantively enacted at

the financial position

reporting date and

whose implementation

is expected over the period in which the deferred tax is

realized or recovered. A deferred tax asset is recognized only to the

extent that it is probable that future taxable profits will

be available against which the asset can be used.

Deferred tax assets

and liabilities are

presented as non-current. Assets

and liabilities are

offset where the

entity has a

legally

enforceable right

to offset current

tax assets and

liabilities or

deferred tax assets

and liabilities,

and the respective

assets

and liabilities

relate to

income taxes

levied by

the same

taxation authority

on the

same taxable

entity or

different

taxable

entities which intend to settle the liabilities and assets on a net

basis.

(g)

Earnings (loss) per share

The Company

presents basic

earnings (loss)

per share data

for its common

shares. Basic

loss per share

is computed

by

dividing net earnings

(loss) by the

weighted average

number of common

shares outstanding

during the year.

Diluted loss

Notes to the Consolidated Financial Statements

For the years ended December 31, 2022 and 2021

(In Canadian dollars)

14

per share is

computed similarly to

basic earnings per

share, except that

the weighted average

number of shares

outstanding

is increased

to include

shares from

the assumed

exercise of

stock options

and share

purchase warrants,

if dilutive.

The

number of additional shares

is calculated by assuming

that outstanding share options and

warrants were exercised and that

the

proceeds

from

such

exercises

were

used

to

acquire

common

shares

at

the

average

market

price

during

the year.

Potential shares from

all outstanding stock

options and share

purchase warrants are excluded

from the calculation of

diluted

loss per share as their inclusion is considered anti-dilutive in

years when a loss is incurred.

(h)

Property and equipment

Property

and

equipment

are

measured

at

cost

less

accumulated

depreciation

and

accumulated

impairment

losses

if

applicable. Cost includes expenditures that

are directly attributable to the

acquisition of the asset

and bringing the asset into

operation. Borrowing

costs capitalized

to asset

under development

represents the

interest expense

calculated under

the

effective interest

method and

does not include

any fair value

adjustments of

investments designated

at fair

value through

profit and loss. Government assistance

and investment tax credits related to

the purchase or development of

property and

equipment

are recorded

in reduction

of the

cost.

When major

parts

of an

item of

property

and

equipment

have different

useful lives, they are accounted for separately. Property and equipment are depreciated from the acquisition date

over their

respective useful life.

Depreciation of

an asset under

construction begins

when it is

available for

use, i.e. when

it is in

the

location and condition necessary for it to be capable of

operating in the manner intended by the Company.

Depreciation is calculated using the following methods

and rates:

Computer equipment

Straight line over

3 years

Machinery and equipment

Straight line over

10 years

Automobiles

Straight line over

7 years

Leasehold improvements

Lesser of the lease term or the useful life (

20 years

)

Impairment losses recognized in prior

periods are assessed at each reporting

date as to whether there are

any indications

that the previously recognized losses may no longer exist or may be decreased. An impairment loss is reversed only to the

extent

that

the

asset’s

carrying

amount

does

not

exceed

the

carrying

amount

that

would

have

been

determined,

net

of

depreciation, had no impairment loss been recognized for the

asset in prior years.

Property and equipment are assessed for impairment

whenever there is an indication of impairment.

Depreciation methods, useful lives and residual

values are reviewed at each financial

year end and adjusted prospectively

if appropriate.

(i)

Leases

Under IFRS 16 Leases, at

inception, the Company assesses

whether a contract is, or contains,

a lease based on whether

the contract conveys the right to control the use of an identified

asset for a period of time in exchange for consideration.

The Company recognizes a right-of-use asset and

a lease liability at the

commencement date of the lease, i.e., the date

the

underlying asset is available for use.

Right-of-use assets

Right-of-use

assets

are measured

at cost,

less

any

accumulated

depreciation

and

accumulated

impairment

losses,

and

adjusted for any remeasurement of lease liabilities. Cost

of right-of-use assets is comprised of:

-

the initial measurement amount of the lease liabilities recognized

;

-

any lease payments made at or before the commencement

date, less any lease incentives received;

-

any initial direct costs incurred; and

-

an estimate of costs to dismantle and remove the underlying

asset, restore the site on which it is located or

restore the underlying asset to the condition required by

the terms and conditions of the lease contract.

PyroGenesis Canada Inc.

Notes to the Consolidated Financial Statements

(In Canadian dollars)

15

Right-of-use assets are

depreciated over the

shorter period of

the lease term

and the useful

life of the underlying

asset. If

a lease transfers ownership

of the underlying asset

or the cost of the

right-of-use asset reflects

that the Company expects

to exercise a purchase option,

the related right-of-use asset is

depreciated over the useful life

of the underlying asset based

on

periods

detailed

above.

The

depreciation

starts

at

the

commencement

date

of

the

lease.

Right-of-use

assets

are

assessed for impairment whenever there is an indication that

the right-of-use assets may be impaired.

Lease liabilities

Lease liabilities are

initially measured at

the present value

of the lease

payments that

are not paid

at the commencement

date over the lease term. The present value of the lease payments is determined

using the lessee’s incremental borrowing

rate at

the commencement date

if the

interest rate implicit

in the

lease is

not readily determinable.

The incremental borrowing

rate is

a function

of the

lessee’s incremental

borrowing rate,

the nature

of the

underlying asset,

the location

of the

asset,

the

length

of

the

lease

and

the

currency

of

the

lease

contract.

Generally,

the

Company

uses

the

lessee’s

incremental

borrowing rate

for the

present value.

At the commencement

date, lease

payments generally

include fixed

payments, less

any

lease

incentives

receivable,

variable

lease

payments

that

depend

on

an

index

(e.g.,

based

on

inflation

index)

or

a

specified rate, and payments of

penalties for terminating the lease,

if the lease term

reflects the lessee exercising the

option

to terminate the lease. Lease payments also include amounts expected to be

paid under residual value guarantees and the

exercise price of a purchase option if the Company is reasonably

certain to exercise that option.

Variable

lease payments that

do not depend on

an index or a

specified rate are not

included in the measurement

of lease

liabilities but

instead are

recognized

as expenses

in the

period in

which the

event or

condition that

triggers the

payment

occurs.

After the

commencement date,

the carrying

amount of

lease liabilities

is increased

to reflect

the accretion

of interest

and

reduced to reflect lease payments made.

In addition, the carrying amount of

lease liabilities is remeasured when

there is a

change in future

lease payments arising

from a change

in an index

or specified rate,

if there is a

modification to the

lease

terms and conditions, a change in the estimate of

the amount expected to be payable under residual

value guarantee, or if

the

Company

changes

its

assessment

of

whether

it

will

exercise

a

termination,

extension

or

purchase

option.

The

remeasurement amount of

the lease liabilities

is recognized as an

adjustment to the right-of-use

asset, or in the

profit and

loss statement when the carrying amount of the right-

of-use asset is reduced to zero.

Classification and presentation of lease-related expenses

Depreciation charge for right-of-use assets, expenses

related to variable lease payments not included in the measurement

of lease

liabilities and

loss (gain)

related to

lease modifications

are allocated

in the

Company’s

profit and

loss statement

based on their function within the Company,

while interest expense on lease liabilities is presented within

finance costs.

Cash flow classification

Lease payments related

to the principal

portion of the

lease liabilities are

classified as

cash flows from

financing activities

while lease

payments related

to the

interest portion

of the

lease liabilities

are classified

as interest

paid within

cash flows

from

financing

activities.

Lease

incentives

received

are

classified

as

cash

flows

from

investing

activities.

Variable

lease

payments not included in the measurement of lease

liabilities are classified as cash flows from operating activities.

(j)

Government assistance and investment tax credits

Investment

tax

credits

are

comprised

of

scientific

research

and

experimental

development

tax

credits.

Government

assistance and investment

tax credits are

recognized when there

is reasonable assurance

of their recovery

and recorded

as a reduction of the related expense or cost

of the asset acquired, as applicable. Investment

tax credits are subject to the

customary

approvals

by

the

pertinent

tax

authorities.

Adjustments

required,

if

any,

are

reflected

in

the year

when

such

assessments are received.

(k)

Intangible assets and Goodwill

Intangible

assets

acquired

separately

are

measured

at

cost

on

initial

recognition.

Following

initial

recognition,

intangible

assets are carried at cost less any accumulated amortization

and any accumulated impairment losses.

Identifiable intangible assets

acquired in a

business combination

are recognized separately

from goodwill if

they meet the

definition of an intangible

asset and if their fair

value can be measured

reliably.

The cost of these

intangible assets equals

their acquisition-date fair value.

Subsequent to initial recognition, identifiable intangible assets acquired in a business combination are

recorded at cost less

accumulated

amortization

and

impairment

losses,

if

they

are

amortizable,

otherwise

only

at

cost

net

of

accumulated

impairment losses. The useful lives of intangible assets

are assessed as either finite or indefinite.

Intangible assets with finite

lives are amortized over

the useful life of

the asset and assessed for

impairment whenever there

is

an

indication

of

impairment.

Amortization

unless they meet specific criteria related to technical, market and financial feasibility in order to be recognized as intangible

assets which include:

-

the technical feasibility of completing the intangible asset so that

it will be available for use or sale;

-

the Company has the intention to complete and the ability to

use or sell the asset;

-

the asset will generate future economic benefits;

-

the Company has the resources to complete the asset; and

-

ability to measure reliably the expenditure during development.

Costs

include legal and other advisor fees to obtain patents,

and patent application fees.

Goodwill represents the future

economic benefits arising from

a business combination that are

not individually identified and

separately

recognized.

Goodwill

is carried

at cost

less

accumulated

impairment

losses.

Goodwill

is not

amortized

but

is

tested for impairment

annually or if

there is an indication

of impairment. Impairment

losses recognized for

goodwill cannot

be reversed.

(l)

Impairment testing of goodwill, other intangible assets,

property and equipment and right-of-use assets

The carrying

amounts of

the Company’s

non-financial

assets are

assessed at

each reporting

date to

determine

whether

there is an indication of impairment. If any such indication

exists, then the asset’s recoverable amount

is estimated.

For impairment assessment purposes, assets are

grouped at the lowest levels

for which there are largely independent

cash

inflows (cash

-generating

units).

As

a result,

some

assets

are tested

individually

for impairment

,

and some

are tested

at

cash-generating unit level. Goodwill is allocated to those

cash-generating units that are expected to benefit from

synergies

of

a

related

business

combination

and

represents

the

lowest

level

within

the

Company

at

which

management

monitors

goodwill.

PyroGenesis Canada Inc.

Notes to the Consolidated Financial Statements

For the years ended December 31, 2022 and 2021

(In Canadian dollars)

17

Cash-generating units to which goodwill

has been allocated are tested for

impairment at least annually.

All other individual

assets

or

cash-generating

units

are

tested

for

impairment

whenever

events

or

changes

in

circumstances

indicate

the

carrying amount may not be recoverable.

The recoverable amount

of an asset

or cash-generating unit

(CGU) is the

greater of its

value in use and

its fair value

less

costs to sell.

In assessing

value in use,

the estimated

future cash flows

are discounted to

their present value

using a pre-

tax discount

rate that

reflects current

market assessments

of the

time value

of money

and the

risks specific

to the

asset.

For the purposes of testing non-financial assets for

impairment, management has identified

one

CGU.

An impairment loss is

recognized if the carrying amount of

an asset or its

CGU exceeds its recoverable amount. Impairment

losses are

recognized in

the consolidated

statements

of comprehensive

loss. Impairment

losses recognized

in respect

of

the CGU are allocated first to reduce the carrying amount of goodwill allocated to the units, and then to reduce the carrying

amounts on a pro-rata basis of the other assets in the

unit.

(m)

Provisions and contingent liabilities

Provisions for legal

disputes, onerous contracts

or other claims

are recognized when

the Company has

a present legal

or

constructive obligation as a result of a past event, it is probable that an outflow of economic resources will be required from

the Company and amounts can be estimated reliably.

The timing or amount of the outflow may still be uncertain.

Provisions are measured at the estimated

expenditure required to settle the

present obligation, based on the

most reliable

evidence available at the reporting date, including the risks and uncertainties associated with the

present obligation. Where

there

are

a

number

of

similar

obligations,

the

likelihood

that

an

outflow

will

be

required

in

settlement

is

determined

by

considering the class

of obligations as a

whole. Provisions are discounted

to their present values,

where the time value

of

money is material.

No

liability

is

recognized

if

an

outflow

of

economic

resources

as

a

result

of

present

obligations

is

not

probable.

Such

situations are disclosed as contingent liabilities unless

the outflow of resources is remote.

(n)

Employee benefits

Share-based payments

The Company applies a fair

value-based method of accounting to

all share-based payments. Employee

and director stock

options are measured

at their fair

value of each

tranche on the

grant date and

recognized in its

respective vesting period.

Non-employee stock options

are measured when

the services are

rendered by the

consultant at the

fair value of

the services

received if the

fair value can

be measured reliably.

In the case

the fair value

of the services

cannot be measured

reliably,

the services are measured

indirectly using the fair

value of the equity

instruments granted at

grant date. The

cost of stock

options is presented

as share-based

payment expense.

On the

exercise of stock

options, share

capital is

credited for

the

consideration received

and for

the fair

value amounts

previously credited

to contributed

surplus. The

Company uses

the

Black-Scholes option-pricing model to estimate the fair value

of share-based payments.

Deferred profit-sharing plan

The Company

established a

yearly Deferred

Profit-Sharing

Plan (“DPSP”)

for all

eligible employees

who have

materially

and

significantly

contributed

to

the

prosperity

and

profits

of

the

Company.

The

significance

of

any

contribution

of

any

employee to the prosperity and profits of the Company for purposes of eligibility in the DPSP is determined by the Board of

Directors of the Company

upon such relevant information

as the Board, in its

sole discretion, may find

relevant. All related

persons to the Company are excluded from participating in

the DPSP.

For all eligible

employees, the Company is

required to contribute to

the DPSP out

of the profits

of the Company. The amount

of the Company’s contribution will be such amount which, in the opinion of its Board of Directors, is

warranted by the profits

and overall financial

position of the

Company.

During the year,

the Company contributed

$

Nil

to the DPSP

($

Nil

in 2021).

Obligations for contributions

to the DPSP

are recognized as

an employee benefit

expense in the

consolidated statements

of comprehensive loss in the periods during which services

are rendered by employees.

Short-term employee benefits

Short-term employee benefit obligations

are measured on an undiscounted

basis and are expensed as

the related service

is provided.

A liability is

recognized for the amount

expected to be

paid under the

short-term incentive plan if

the Company has a

present

legal or constructive obligation

to pay this amount as

a result of past service

provided by the employee,

and the obligation

can be estimated reliably.

(o)

Equity instruments

Issuance of equity instruments

Incremental

costs

directly

attributable

to

the

issue

of

equity-classified

shares

are

recognized

as

a

deduction

from

the

common

shares

and

warrants,

net

of

any

tax

effects.

Upon

issuance

of

units,

the

Company

uses

the

residual

value

to

allocate the net proceeds between common shares and

warrants.

Extinguishing financial liabilities with equity instruments

When

equity

instruments

issued

to

a

creditor

to

extinguish

all

or

part

of

a

financial

liability

are

recognized

initially,

the

Company

measures

them

at

the

fair

value

of

the

equity

instruments

issued,

unless

that

fair

value

cannot

be

reliably

measured. If the fair

value of the equity

instruments issued cannot

be reliably measured,

then the equity instruments

shall

be measured to reflect the fair value of the financial liability

extinguished.

Contributed surplus

Contributed

surplus

includes

amounts

related

to

equity-settled

share-based

payments

until

such

equity

instruments

are

exercised or settled, in which case the amounts are transferred

to common shares or reversed upon forfeiture if not vested.

It also includes the unexercised conversion option at the

maturity of the convertible debentures.

(p)

Financial Instruments

Recognition:

The Company

recognizes a

financial asset

or a

financial liability

when it

becomes a

party to

the contractual

provisions of

the instrument.

Purchases

or

sales

of

financial

assets

that

require

delivery

of

assets

within

the

time

frame

generally

established

by

regulation or

convention in

the marketplace

(regular way

trades) are

recognized on

the trade

date, i.e.,

the date

that the

Company commits to purchase or sell the asset.

Classification

Financial

assets

are

classified

at

amortized

cost,

fair

value

through

profit

or

loss

(“FVTPL”)

or

fair

value

through

other

comprehensive

income

(“FVOCI”)

based

on

the

Company’s

business

model

for

managing

the

financial

assets

and

the

contractual cash flow characteristics of these assets.

Assessment and decision on the business model

approach used is an

accounting judgment.

A financial

asset

is measured

at amortized

cost

if it

is held

within

a business

model

whose

objective

is to

hold financial

assets in order to collect contractual cash flows and its contractual terms give rise on specified dates to cash flows that are

solely payments of principal and interest on the principal amount outstanding. The Company

includes in this category cash

and cash equivalents, trade accounts receivable, other receivables,

royalties receivable and deposits.

A financial asset is measured at fair value through profit or

loss (“FVTPL”) if:

(a)

Its contractual terms do not give rise to

cash flows on specified dates that are

solely payments of principal and interest

(SPPI) on the principal amount outstanding; or

(b)

It

is

not

held

within

a

business

model

whose

objective

is

either

to

collect

contractual

cash

flows,

or

to

both

collect

contractual cash flows and sell; or

(c)

At

initial

recognition,

it

is

irrevocably

designated

as

measured

at

FVTPL

when

doing

so

eliminates

or

significantly

reduces a measurement or

recognition inconsistency that would

otherwise arise from

measuring assets or

liabilities or

recognizing the gains and losses on them on different

bases.

The Company includes in this category strategic investments

in equity instruments.

All financial liabilities,

other than

those measured

at fair

value through

profit or

loss, are

included in the

financial liabilities

measured at

amortized cost.

The Company

includes in

this category

bank indebtedness,

accounts payable

and accrued

liabilities and term loans. The balance due on business

combination is measured at FVTPL.

Initial measurement

Financial assets and

liabilities (other than

financial assets at

FVTPL) are measured

initially at

their fair value

plus any directly

attributable incremental costs of acquisition or issue.

Financial assets

and financial

liabilities at

FVTPL are

recorded in

the consolidated

statements

of financial

position at

fair

value. All transaction costs for such instruments are recognized

directly in profit or loss.

Subsequent measurement

Financial assets (other than financial assets at FVTPL) are measured at amortized

cost using the effective interest method

less

any

allowance

for

impairment.

Gains

and

losses

are

recognized

in

profit

or

loss

when

the

debt

instruments

are

derecognized or impaired, as well as through the amortization

process.

Financial liabilities are

measured at amortized

cost using the

effective interest

method except for

derivatives and financial

liabilities designated at

FVTPL. Gains and

losses are recognized

in profit or

loss when the

liabilities are derecognized,

as

well as through

the amortization

process. Changes

in fair value

of financial liabilities

attributable to changes

in the entity’s

own credit risk are to be presented in other comprehensive

income unless they affect amounts recorded

in income.

Fair value measurement principles

Fair value is the price that would be received to sell

an asset or paid to transfer a liability in an orderly

transaction between

market participants at the measurement date.

Where financial assets and

financial liabilities measured

at fair value though

profit or loss have

a quoted price in

an active

market at the reporting date,

the fair value is based

on this price. A financial

instrument is regarded as

quoted in an active

market if

quoted prices

are readily

and regularly

available from

a stock

exchange and

those prices

represent actual

and

regularly occurring market transactions on an arm’s

length basis.

Securities traded on stock exchanges are stated at market

price based on the closing price on the

relevant valuation day.

Derecognition

A financial asset is derecognized

where the rights to receive

cash flows from the asset

have expired, or the Company

has

transferred its

rights to receive

cash flows

from the asset.

The Company derecognizes

a financial liability

when the obligation

under the liability is discharged, cancelled,

or expired.

Offsetting of financial instruments

Financial assets and financial

liabilities are offset,

and the net amount

reported in the

consolidated statements

of financial

position if, and only if, there is a currently enforceable

legal right to offset the recognized amounts

and there is an intention

to settle on a net basis, or to realize the assets and settle

the liabilities simultaneously.

this impairment model

are cash and

cash equivalents,

trade and other

receivables,

costs and profits in excess of billings on uncompleted

contracts, royalties receivable and deposits.

The trade accounts receivable have no financing component

and have maturities of less than 12 months

at amortized cost

and,

as

such,

the

Company

applies

the

simplified

approach

for

expected

credit

losses

(ECLs)

to

all

its

trade

accounts

receivable. Therefore, the Company recognizes a loss

allowance based on lifetime ECLs at each reporting date.

The Company’s

approach to

ECLs reflects

a probability-weighted

outcome, the

time value

of money

and reasonable

and

supportable

information

that

is

available

without

undue

cost

or

effort

at

the

reporting

date

about

past

events,

current

conditions, and forecasts of future economic conditions.

The Company

uses

the

provision

matrix

as a

practical

expedient

to

measure

ECLs

on

trade

receivables

and

costs

and

profits in excess of billings on uncompleted contracts, based on days past due for

groupings of receivables with similar loss

patterns. Contracts with particular

recovery history are analysed

separately from other accounts.

The loss rates are based

on historical observed loss rates over the expected life of the receivables and are adjusted for forward-looking estimates to

reflect differences between economic conditions

during the period over which the historical data has been collected.

Impairment

losses

are

recognized

in

profit

or

loss

and

reflected

in

an

allowance

account

presented

in

reduction

of

receivables and cost in excess of billings on uncompleted

contracts.

Write-off

The

gross

carrying

amount

of

a

financial

asset

is

written

off

when

the

Company

has

no

reasonable

expectations

of

recovering a financial asset in its entirety or a portion thereof.

Failure to engage and communicate with

the Company on alternative payment arrangements and

failure to make payments

within 90

days, amongst

others, are

considered possible

indicators of

no reasonable

expectation of

recovery of

accounts

receivable.

Effective Interest Method

The

effective

interest

method

is

a

method

of

calculating

the

amortized

cost

of

a

financial

asset/financial

liability

and

of

allocating

interest

income/expense

over

the relevant

period. The

effective

interest

rate is

the

rate

that

exactly

discounts

estimated

future

cash

receipts/payments

(including

all

fees

and

points

paid

or

received

that

form

an

integral

part

of

the

effective

interest

rate,

transaction

costs

and

other

premiums

or

discounts)

through

the

expected

life

of

the

financial

instrument, or (when appropriate) a shorter period, to the net

carrying amount on initial recognition.

Future Changes and Amendments to Accounting Standards

and Interpretations

i)

IAS 1

Presentation of Financial Statements - Accounting Policies

In

2021,

the

IASB

amended

IAS

1,

Presentation

of

Financial

Statements,

to

require

entities

to

disclose

their

material

accounting policy information rather than their significant accounting policies. Additional amendments to IAS 1 are made to

explain how an entity can identify

a material accounting policy.

The amendments are effective

for annual reporting periods

beginning on or after January 1, 2023, with earlier application

permitted.

ii)

IAS 1

Presentation of Financial Statements - Classification of Liabilities

The

IASB

released

Classification

of

Liabilities

as

Current

or

Non-current

(Amendments

to

IAS

1),

which

clarifies

the

guidance in IAS 1 Presentation

of Financial Statements on whether

a liability should be classified

as either current or non-

current

relating

to

the

right

to

defer

settlement

of

the

liability

for

at

least

twelve

months

after

the

reporting

date.

The

amendment is effective

for annual reporting

periods beginning on

or after January 1,

2023, with earlier

application permitted.

iii)

IAS 12

Income Taxes

The IASB released

Deferred Tax

Related to Assets

and Liabilities Arising

from a Single

Transaction (Amendments

to IAS

12). The amendment relates

to the recognition of deferred

tax when an entity

accounts for transactions, such

as leases or

decommissioning obligations, by recognizing both an asset and a liability. The objective of this amendment is to narrow the

initial recognition exemption

in paragraphs 15

and 24 of

IAS 12, so

that it would

not apply to

transactions that give

rise to

both taxable and deductible temporary differences,

to the extent the amounts recognized for the temporary

differences are

the

same.

The

amendment

is

effective

for

annual

reporting

periods

beginning

on

or

after

January 1,

2023,

with

earlier

application permitted.

iv)

IAS 37

Provisions, Contingent Liabilities and Contingent Assets

The IASB

released Onerous

Contracts -

Cost of

Fulfilling a

Contract (Amendments

to IAS

37). The

amendments specify

which costs an

entity includes in

determining the cost

of fulfilling a

contract for the

purpose of assessing

whether the contract

is onerous.

Costs

to be

included

comprise

the costs

that

relate directly

to the

contract,

which

includes

both

incremental

costs of fulfilling the contract and an allocation

of other costs that relate directly to

fulfilling the contract. The amendment

is

effective for annual reporting periods beginning

on or after January 1, 2023, with earlier application permitted.

The Company has determined that the adoption of these standards or amendments will not have a significant impact on its

consolidated financial statements as of the date of adoption.

5.

Significant accounting judgments, estimates and assumptions

The preparation of

consolidated financial statements requires management

to make judgments, estimates

and assumptions

based on

currently

available information

that affect

the

reported amounts

of assets,

liabilities and

contingent

assets and

liabilities at the

date of the

consolidated financial

statements and

reported amounts

of revenues and

expenses during the

reporting period.

Estimates and

judgments are

continuously evaluated

and are

based on

management’s

experience and

other factors, including expectations of future events

that are believed to be

reasonable under the circumstances. However,

actual

results

could

differ

from

those

estimated.

By

their

very

nature,

these

estimates

are

subject

to

measurement

uncertainty and the effect of any changes in estimates

on the financial statements of future periods could be

material.

In the process of applying the Company’s

accounting policies, management has made the following

judgments, estimates,

and assumptions which

have the most

significant effect on the

amounts recognized in the

consolidated financial statements.

Critical judgments in applying accounting policies

(a)

Assessment of

whether there

is any

indication that

property and

equipment, right-of-use

assets and

intangible assets

may be impaired

At each reporting date,

the Company reviews

the carrying amounts

of its property and

equipment, right-of-use assets

and

intangible assets

with a

finite useful

life to

determine whether

there is

any indication

of impairment.

If any

such indication

exists, then the

asset’s recoverable

amount is estimated.

Management’s judgment

is required in

assessing whether

there

is any indication that an asset may be impaired.

(b)

Intangible assets

The recognition of development costs as intangible

assets requires judgments to determine whether the

required criteria for

recognition are met including management estimates of future

economic benefits.

(c)

Sale of intellectual property and related royalties

The recognition

of variable

consideration related

to the

sale of

intellectual property

requires management’s

judgments to

determine

whether

it

is

highly

probable

that

a

reversal

will

not

occur

when

the

uncertainty

associated

with

the

variable

consideration is subsequently resolved.

(d)

Investment tax credits receivable

The investment tax credits are estimated

by management based on quantitative

and qualitative analysis and interpretation

of various government programs,

related restrictions, limitations,

definitions, and eligibility

conditions. Uncertainty over

the

eligibility and final assessment by taxation authorities of investment

tax credits requires judgment. Management involves its

technical staff

and external

specialists in

determining if

the expenditures

meet the

requirements of

the different

tax credit

claims.

Key sources of estimation uncertainty

(e)

Revenue recognition

Revenue recognition for long-term contracts completion requires the use of estimates to determine the recorded amount of

revenues, costs in excess of billings and billings in excess

of costs and profits on uncompleted contracts.

The determination of anticipated

costs for completing

a contract is based on

estimates that can

be affected by a

variety of

factors,

including

the

cost

of

materials,

labour

and

sub-contractors,

as

well

as

potential

claims

from

customers

and

subcontractors.

As risks and

uncertainties are different for

each project, the

sources of variations between

anticipated costs and actual

costs

incurred will also vary by project. The determination

of estimates is based on the Company’s

business practices as well as

its historical experience. Estimates are reviewed on an ongoing basis. Revisions to accounting estimates are recognized in

the period in which the estimate is revised.

Given

this

estimation

process,

it

is

possible

that

changes

in

future

conditions

could

cause

a

material

change

in

the

recognized amount of revenues

and costs and

profits in excess of

billings on uncompleted contracts

and accrued expenses.

Agreements that

contain multiple

deliverables require

the use

of judgment

to determine

whether they

contain separately

identifiable performance obligations and to allocate the consideration

received to each performance obligation.

(f)

Share-based payments

The Company uses the

fair value method

of valuing compensation

cost associated with

the Company’s

stock option plan.

Estimating fair value

requires determining the

most appropriate valuation

model for a grant

of equity instruments,

which is

dependent

on

the

terms

and

conditions

of

the

grant.

This

also

requires

determining

the

most

appropriate

inputs

to

the

valuation model including the

expected life of the option

and volatility.

The assumptions and models

are discussed in note

22.

(g)

Useful lives of property and equipment and intangible

assets

The Company estimates

the useful lives

of property and

equipment and intangible

assets based on

the period over

which

the assets are expected to be available

for use. The estimated useful lives of property and equipment and intangible

assets

are reviewed periodically and are updated

if expectations differ from previous

estimates due to physical wear and tear

and

legal or other

limits on the

use of the

relevant assets. In addition,

the estimation of

the useful lives

of property and

equipment

and intangible assets are based

on management’s experience with similar assets. It

is possible, however, that future results

of

operations

could

be

materially

affected

by

changes

in

the

estimates

brought

about

by

changes

in

factors

mentioned

above. The

amounts and

timing of

recorded expenses

for any

period would

be affected

by changes

in these

factors and

circumstances. Useful lives, depreciation and amortization

rates and residual values are reviewed at least annually.

(h)

Impairment of non-financial assets and goodwill

In assessing impairment,

management estimates the

recoverable amount

of each asset or

cash generating unit

based on

expected future cash flows and uses an interest rate to discount them. Estimation uncertainty relates to assumptions about

future operating results and the determination of a suitable

discount rate (see note 4 (l)).

(i)

Fair value of strategic investments

Where the fair

values of investments

recorded in the

consolidated statements

of financial position

cannot be derived

from

active markets,

they

are

determined

using

valuation

techniques

including

the

Black-Scholes

model.

The

inputs

to

these

models are taken from observable markets where possible, but where

this is not feasible, a degree of judgment is required

in establishing the fair values. The judgments

include considerations of inputs such as the expected volatility

and the initial

allocation of the consideration paid between the fair value of the common shares and warrants

received. Should any of the

inputs to these models or changes in assumptions about

these factors occur,

this could affect the reported fair value of the

investments.

(j)

Right-of-use assets and lease liabilities

In determining

the carrying

amount of

the right-of-use

assets and

corresponding lease

liabilities, assumptions

include the

non-cancellable term of the lease

plus periods covered by an

option to renew or purchase

the assets, estimated useful lives

of the related assets, and incremental borrowing

rate. Renewal and purchase options are only

included in the lease term if

management is reasonably certain to renew.

Management considers factors such as market conditions, comparable

rental

rates and similar property values. The

Company is also required to estimate the incremental borrowing

rate specific to each

portfolio of leased assets with similar characteristics

if the interest rate in the lease is not readily

determined. Management

determines the incremental borrowing rate using the base

rate for similar loans plus a risk premium.

(k)

Income taxes

The Company has unused available tax

losses, deductible temporary differences and investment tax

credits. The Company

recognizes deferred income tax assets for these unused tax losses and deductible temporary differences only to the extent

that, in

management’s

opinion, it

is probable

that future

taxable profit

will be

available against

which these

available tax

losses and temporary differences

can be utilized. The Company recognizes

investment tax credits when it

has reasonable

assurance

that

it

has

complied

with

the

conditions

of

the

program

and

that

the

amounts

will

be

realized

(i.e.

that

it

will

generate future federal income taxes

payable against which the tax

credits can be applied). The

Company’s projections of

future taxable profit

involve the use

of significant assumptions

and estimates with

respect to a

variety of factors,

including

future sales

and operating

expenses. There

can be

no assurance

that the

estimates and

assumptions used in

our projections

of future

taxable

income will

prove to

be accurate

predictions

of the

future,

and in

the event

that

our assessment

of the

recoverability of these deferred tax

assets and investment tax credits

changes in the future, a

material increase or reduction

in the carrying value of

these deferred tax assets and

investment tax credits could be required, with

a corresponding charge

to net loss.

(l)

Business combinations

Fair value of assets acquired and liabilities assumed in a

business combination is estimated based on information available

at

the

date

of

acquisition

and

involves

considerable

judgment

in

determining

the

fair

values

assigned

to

the

identifiable

assets acquired and liabilities

assumed on acquisition. Among

other things, the determination

of these fair values involves

the

use

of

discounted

cash

flow

analyses

and

estimated

profit

margins

on

contracts

in

progress.

In

addition,

the

determination of the

contingent consideration due on

the business combination

is based on

the estimations of

the probability

and timing of completing the predetermined milestones

(see note 6);

(m) COVID-19 pandemic

The COVID-19

pandemic continues

to cause

significant financial

market and

social dislocation.

The situation

is dynamic

with various cities and

countries around the world responding

in different ways to address

the outbreak. While the

Company

has experienced

the impact

of the outbreak

of the Coronavirus

(COVID 19)

on its

operations, it

had continued

to operate

during the

current

pandemic.

In the

event of

a prolonged

continuation

of the

pandemic,

it is

not clear

what

the potential

impact may be on the Company’s business,

financial position and financial performance.

6.

Business combination

On August 11, 2021, the Company completed the

acquisition of Pyro Green-Gas

Inc. and its

subsidiaries, a Montreal-based

company

which

offers

technologies,

equipment,

and

expertise

in

the

area

of

biogas

upgrading,

as

well

as

air

pollution

controls, for

a maximum

purchase price

consideration of $

4,355,600

in cash,

subject to customary

post-closing adjustments.

PyroGenesis Canada Inc.

Notes to the Consolidated Financial Statements

For the years ended December 31, 2022 and 2021

(In Canadian dollars)

24

In addition, the Company settled

a pre-existing loan receivable from Pyro

Green-Gas Inc. of approximately $

1,744,000

. The

transaction was executed

through a purchase

of the entirety of

the common class

“A” shares of Pyro

Green-Gas Inc. This

acquisition

enables

the

Company

to

springboard

into

the

renewable

natural

gas

market

and

provides

an

advantage

compared

to building

its own

operations.

In addition,

the Company

will now

have

a presence

in Italy

and

India, and

the

acquisition will provide potential synergies with the Company’s land-based waste

destruction offerings. The purchase price

will

be

paid

upon

the

achievement

of

various

contract

and

business-related

milestones

by

Pyro

Green-Gas

Inc.

The

Company’s assessment

is that

these milestones

will be

realized at

various moments

during the

next

30 months

following

the date of the acquisition. The contingent consideration

was estimated using a discount rate of

8

%.

The goodwill of $

2,660,607

recorded on the transaction

is mainly attributable

to the expected growth

in biogas upgrading market

and

the expertise of the workforce, and it is not expected to be deductible for tax purposes.

During the

period ended

December 31, 2021,

the Company recognized

revenue of $

6,800,090

and net

earnings of

$807,395

related to the operations generated by Pyro Green-Gas

Inc. since the acquisition date.

In connection with

this acquisition, the

Company incurred acquisition-related

costs of $

the discounting of

the non-interest-bearing

loan from the Economic Development Agency of Canada,

representing government assistance (see note 21).

Equipment under

construction included

  1. Leases

The Company has entered into lease contracts mainly for buildings

and computer equipment, which expire at various dates

through

the

year

2036.

Some

leases

have extension

or purchase

options

for various

terms.

The

lease

contracts

do not

impose any financial covenants.

On January 1, 2022, a lease for rent

of a property with a trust whose

beneficiary is the controlling shareholder

and CEO of

the

Company,

was

modified

to

extend

the

lease

term

until

December

2026.

The

lessor

also

reimbursed

an

amount

of

$

1,070,264

representing the balance at

the date of modification

of the original prepayment

amount of $

1,178,530

made in

  1. At

the date

of modification,

the

lease

liability was

remeasured

using

a discount

rate

of

4

%. As

a result,

the

lease

liability was increased by an amount of $

1,070,264

and the right-of-use assets was decreased by an amount

of $

108,267

.

On September

1, 2022,

a lease

of a

property was

modified to

extend the

term, to

postpone the

exercise of

the purchase

option of the property,

and to factor a

deposit of $

275,000

required to exercise

the purchase option.

As a result, the

lease

liability was remeasured using a discount rate of

8.6

% and the lease liability and the right-of-use assets were decreased by

$

203,154

.

  1. Goodwill

The

Company

tests

goodwill

for

impairment

annually,

or

more

frequently

when

an

indicator

of

impairment

is

identified.

Goodwill is considered impaired if the recoverable amount

is less than the carrying amount.

The recoverable

amount of

an operating

segment

is determined

based on

value-in-use

calculations,

covering a

detailed

five-year forecast, followed

by an

extrapolation of expected

cash flows for

the remaining useful

lives using a

declining growth

rate determined by management. The present value of the expected

cash flows of the operating segment is determined by

applying a suitable discount rate reflecting current market assessments of the time value of money and risks specific to the

segment.

At December

it

was

determined

that

the

recoverable

amounts

exceed

the

carrying

amount,

and

no

impairment was required.

The recoverable

amount in the

most recent

impairment test

performed was

determined using

a

pre-tax discount rate of

12.5

% and terminal growth rate of

2

% (2021 - pre-tax discount rate of

trade

accounts receivable with

amounts owing to

the Company of

$

18,894,727

(2021 - $

12,063,636

), representing the

Company's

major

credit

risk

exposure.

Credit

concentration

is

determined

based

on

customers

representing

10

%

or

more

of

total

revenues and/or total accounts receivable.

Credit risk

Credit

risk

is

the

risk

that

one

party

to

a

financial

instrument

will

cause

a

financial

loss

for

the

other

party

by

failing

to

discharge an obligation.

The maximum credit

risk to which

the Company is

exposed as at

December 31, 2022

represents

the carrying amount

of cash

and cash equivalents,

accounts receivable

(except sales

tax receivable),

costs and

profits in

excess of billings on uncompleted contracts, deposits and

royalties receivable.

Cash and cash equivalents,

which only comprise guaranteed

investment certificates redeemable

on relatively short

notice

by the Company,

are held with major reputable financial institutions.

Management has established

a credit policy

under which each

new customer

is analysed individually

for creditworthiness

before

the

Company’s

payment

and

delivery

terms

and

conditions

are

offered.

The

Company’s

review

could

include

reviewing external ratings, if they are available,

financial statements, credit agency information,

industry information and in

some cases bank

references. The Company’s

exposure to credit

risk is mainly

influenced by the

individual characteristics

of each customer. In monitoring customer

credit risk, customers are

identified according to their

characteristics such as their

geographic location, industry,

trading history with the Company and existence of previous

financial difficulties.

The Company does not generally

require collateral or other security

from customers on accounts

receivable,

however, the

contract terms may include the

possibility of recourse in the

event of late payment.

The Company believes that

there is

no

unusual exposure associated with the collection of these

receivables.

The credit risk associated with costs and profits in excess of billings on uncompleted contracts is similar to that of accounts

receivable, as these amounts are accumulated and converted to

accounts receivable as invoicing milestones are reached.

The royalties receivable

are due from

a company in

which the Company

has a strategic

investments. The Company

does

not have

collateral or

other security

associated with

the collection

of this

receivable. The

carrying amount

of the

royalties

of money and credit risk of the counterparty.

no loss

allowance has been

recognized in

connection with these

deposits and

the maximum exposure

is the

carrying amount

of these deposits.

During the

years 2022

and 2021,

provisions for

expected credit

losses were

recorded, however,

no

amounts

of financial

assets have been written off. The accounts provisioned by

the loss are still subject to

enforcement activity in order to collect

the balances due.

Interest rate risk

Interest rate risk is the risk that the

value of a financial instrument might be adversely affected by a change in interest rates.

Changes in market interest rates may have an effect on

the cash flows associated with some financial assets and liabilities,

known as cash flow

risk, and on the

fair value of other

financial assets or liabilities, known as

price risk, and on the

fair value

of investments

or liabilities,

known as

price risks.

The Company

is exposed

to a

risk of

fair value

on term

loans as

those

financial instruments bear

interest at

fixed rates

and to

cash flow

risk from

the variable

interest rate

of the

bank indebtedness.

Price risk

Price risk

is the

risk that

the fair

value or

future cash

flows of

a financial

instrument will

fluctuate because

of changes

in

market price (other

than those arising

from foreign

currency risk

and interest risk),

whether those

changes are

caused by

factors specific to the individual financial instrument or its issuers or factors affecting

all similar financial instruments traded

in the

market. The

most significant

exposure to

the price

risk for

the Company

arises from

its investments

in shares

and

warrants of public

companies quoted

on the TSX

Venture Exchange.

If equity prices

had increased or

decreased by

25

%

as

at

December 31,

2022,

with

all

other

variables

held

constant,

the

Company’s

investments

would

have

increased

or

decreased respectively,

by approximately $

1,841,484

(December 31, 2021 - $

4,042,000

).

Liquidity risk

Liquidity risk is the

risk that the

Company will encounter

difficulty in meeting

obligations associated with

financial liabilities

that are settled

by delivery of

cash or another

financial asset. The

Company manages its

liquidity risk by forecasting

cash

flows from operations and anticipating any investing and financing

activities.

The Company's

Canadian subsidiary

benefits from

of credit

of $

the Italian

subsidiary benefits

from a

400,000

Euros ($

576,000

) line of credit. At December 31, 2022, $

498,200

was drawn on the Canadian facility and

341,473

Euros ($

493,702

) was drawn on

the Italian facility. The credit facilities

both bear interest at

variable rates which is

the bank’s

prime rate plus 1%

, therefore,

7.45

% for the Canadian facility and

8

% for the Italian facility. There

are no imposed financial

covenants on the credit facilities.

Fair value of financial instruments

The fair value represents

the amount that

would be received

for the sale of

an asset or paid

for the transfer of

a liability in

an orderly transaction

between market

participants at the

measurement date.

The fair value

estimates are calculated

at a

specific date

taking into

consideration assumptions

regarding the

amounts, the

timing of

estimated future

cash flows

and

discount rates.

Accordingly,

due to

its approximate

and subjective

nature, the

fair value

must not

be interpreted

as being

realizable in an immediate settlement of the financial instruments.

There

are

three

levels

of

fair

value

that

reflect

the

significance

of

inputs

used

in

determining

fair

values

of

financial

instruments:

Level 1 — quoted prices (unadjusted) in active markets

for identical assets or liabilities.

Level 2 — inputs other than quoted prices included within Level

1 that are observable for the asset or liability, either directly

(i.e. as prices) or indirectly (i.e. derived from prices).

Level 3 — inputs for the asset or liability that are not based

on observable market data.

The fair values

of cash

and cash

equivalents, trade

accounts receivable,

other receivables,

deposits, bank

indebtedness,

accounts payable and accrued liabilities approximate their carrying

amounts

due to their short-term maturities.

Investments in BGF and HPQ shares are valued at quoted

market prices and are classified as Level 1.

Royalties receivable are discounted according to their corresponding

agreements and are classified as Level 2.

Investments in HPQ warrants are valued using the Black

-Scholes pricing model and are classified as Level 3 (note

11).

The fair value

of the term

loans and the

balance due on business

combination as at December 31,

2022 is determined using

the

discounted

future

cash

flows

method

and

management's

estimates

for

market

interest

rates

for

similar

issuances.

Accordingly, as a result

,

their fair market values correspond to their carrying amount. The term loans are classified

as level

2 and the balance due on business combination as Level 3.

Contingent liabilities

The

Company

is

currently

a

party

to

various

legal

proceedings.

If

management

believes

that

a

loss

arising

from

these

proceedings is

probable and

can reasonably

be estimated,

that amount

of the

loss is

recorded. As

additional information

becomes

available,

any

potential

liability

related

to

these

proceedings

is

assessed

and

the

estimates

are

revised,

if

necessary. Based on currently available information, management

believes that the ultimate

outcome of these proceedings,

individually and in

aggregate, will not

have a material

adverse effect on

the Company’s

financial position or

overall trends

in results of operations.

The Company had received a government grant in prior years of approximately $

800,000

to assist with the development of

a new system of advanced waste treatment systems technology. The grant

is potentially repayable at the rate of

3

% of any

consideration received

as a

result of

the project,

for which

funding has

been received,

to a

maximum of

the actual

grant

received. This repayment

provision will remain

in effect

until May 30,

  1. The Company

abandoned the

project in 2011

and accordingly,

no

amount is expected to be repaid.

30.

CODE OF BUSINESS CONDUCT AND ETHICS

INTRODUCTION

Every employee, officer and director of PyroGenesis Canada Inc. (the “

Company

”) and its subsidiaries occupies a position

of trust. In varying measures, individuals, as

well as certain contractors and agents,

represent the Company in its relations

with

others

whether

with

customers,

suppliers,

employees,

competitors,

governments,

investors

or

the

general

public.

Whatever the area

of activity and

whatever the degree

of responsibility, such persons are

expected to act

honestly, ethically,

with integrity and in compliance with applicable laws and regulations.

This

Code

of

Business

Conduct

and

Ethics

(this

Code

”)

was

adopted

by

the

board

of

directors

of

the

Company

(the

Board

”) as a guide that is intended, among other things, to sensitize such individuals to significant legal

and ethical issues

that

arise

frequently

and

to

the

mechanisms

available

to report

illegal

or

unethical

conduct,

and

provide

assurance

that

reporting of questionable behavior

is protected and encouraged.

It does not purport to

address every legal or

ethical issue

that may be encountered.

Moreover, the

specific requirements of

applicable law in certain

jurisdictions where we

currently

operate or may operate in the future may impose a higher standard than is specifically

set forth in this Code. Ultimately,

no

code of conduct can replace the thoughtful behavior of

a person acting honestly,

ethically and with integrity.

Compliance

with

this

Code

is

mandatory

for

all

employees,

officers

and

directors

of

the

Company.

Certain

contractors,

agents and

other representatives

of the

Company may

also be

required to

comply with

this Code.

Failure to

comply with

this Code, including

a failure to

report a violation

of this Code,

can have severe

consequences.

Conduct that

violates this

Code may violate

applicable laws and

subject both

the Company and

its employees,

officers and

directors to

prosecution

and legal sanctions. The Company may discipline those who violate this Code, up to and including discharge from office or

termination of employment or engagement with the Company.

The Company

has set

forth

in

writing

numerous

policies,

procedures,

codes,

rules and

standards

of performance

(all

of

which

continue

in

force)

and

may

create

new

policies,

procedures,

codes,

rules and

standards

in

the

future.

This

Code

supplements, but does

not replace such

other policies, procedures, codes,

rules and standards of performance.

In the event

of a

conflict or

inconsistency

between this

Code and

any other

written policies,

procedures, codes,

rules or standards

of

performance of

the Company

this Code shall

prevail unless

the conflicting

or inconsistent

policy,

procedure, code,

rule or

standard

of

performance

imposes

an

additional

and/or

higher

obligation

or

standard,

in

which

case

the

conflicting

or

inconsistent policy,

procedure, code, rule or standard of performance shall control.

Employees, officers or directors with questions about this

Code or any policies, rules and employee performance standards

should consult

a senior

officer.

Any employee,

officer

or director

who is

concerned

about conduct

that they

believe may

violate

this

Code,

such

policies,

rules and

employee

performance

standards

or

applicable

law,

should

consult

a

senior

officer.

Procedures for reporting suspected violations of this Code

are set out under “Compliance” below.

NO RETALIATION

The Company will not permit any

form of retaliation (including discharge, demotion, suspension, threats,

harassment or any

other form of discrimination) against an employee who

has truthfully and in good faith:

(a)

reported violations of this Code;

(b)

lawfully

sought

advice

about

providing

information,

expressed

an

intention

to

provide

information

or

provided

information

or assistance

regarding

any conduct

which

the

employee

reasonably

believes

constitutes

a criminal

offense or other violation of law;

(c)

cooperated, filed, caused to be

filed, testified, participated in

or otherwise assisted in, or

expressed an intention to

do any of the foregoing, in an investigation or proceeding related

to a criminal offense or other violation of

law; or

(d)

provided a law enforcement officer

with truthful information regarding

the commission or possible commission

of a

criminal offence or other violation of law,

unless the individual reporting is one of the violators.

Any retaliation against an

employee who has truthfully

and in good faith

done any of the

foregoing in accordance

with this

Code will result in discipline, up to and including dismissal.

  • 2 -

CONFLICT OF INTEREST AND DISCLOSURE ISSUES

Conflicts of Interest

Employees, officers and directors owe a duty to the Company to advance its legitimate

interests when the opportunity to do

so arises

and

to

refrain

from

activities

which

could

hinder

their

ability

to

act in

the

Company’s

best

interest

or have

the

potential or could be perceived

as doing so, including to

avoid all situations in which

their personal interests conflict,

might

conflict or

could be

perceived to

conflict with

their duties

to the

Company.

In particular,

employees, officers

and directors

should seek to avoid acquiring any interests or participating

in any activities that would tend to:

(a)

deprive the Company of the time or attention required to perform

their duties properly; or

(b)

create an obligation or

distraction which would affect their judgement or

ability to act solely

in the Company’s best

interest.

Employees

charged

with

executive,

managerial

or

supervisory

responsibility

are

required

to

see

that

actions

taken

and

decisions made

within their

jurisdiction are

free from

the influence

of any

interests that

might reasonably

be regarded

as

conflicting with those of the Company.

Employees, officers and directors owe a duty to the Company to advance its legitimate interests when

the opportunity to do

so arises

and

to

refrain

from

activities

which

could

hinder

their

ability

to

act in

the

Company’s

best

interest

or have

the

potential or

could

be perceived

as doing

so. Employees

are required

to disclose

in writing

to the

Company

all business,

commercial

or

financial

interests

or

activities

that

might

reasonably

be

regarded

or

perceived

as

creating

an

actual

or

potential conflict with

such duties. In addition,

directors and officers are

required under corporate law

to disclose any

interest

in and

refrain from

voting on

any material

contracts or

transactions relating

to the

Company in

which they

are a

party or

have a material

interest.

A

senior officer must

be contacted in

advance to co-ordinate

the approval of

such material contracts

or transactions.

Outside Employment and Business Activities

Employees may take on employment

and engage in or otherwise

invest in business ventures,

partnerships or enterprises,

but

only

outside

their

working

hours

and

with

the

approval

of

a

senior

officer.

However,

employees

must

avoid

outside

employment, businesses and

other activities

which would impair

their effective performance

as a

Company employee, which

could have an

adverse impact

on the business

or reputation

of the Company

or which might

create or

appear to create

a

conflict with the best interests of the Company.

For

these

reasons,

it

is

important

for

there

to

be

current

and

complete

disclosure

of

any

such

outside

employment

or

business ventures, partnerships or enterprises

that any employee, officer or

director may have. Such disclosure

should be

made promptly

to a

senior officer and

should also

be listed

in any

acknowledgement of this

Code requested

by the

Company.

See also “Personal Gain”, “Company

Confidential Information”, “Intellectual

Property”, “Use of Company

Assets” and “Use

of Technology”

below.

Community Activities

Employees,

officers

and

directors

may,

and

are

encouraged

to,

engage

in

community

and

volunteer

work

and

activities

outside

their

working

hours,

and

to

uphold

a

commitment

to

community

in

all

their

activities.

Requests

for

donation

or

sponsorship by

the Company

or from

Company assets,

including employee

work time,

must be

made only in

accordance

with

the

Company’s

applicable

established

policies,

procedures,

codes,

rules and

standards

and

within

any

established

budget therefor or, alternatively,

may be submitted to a senior officer and, in such case, may only be approved by the Chief

Executive

Officer,

Chief

Financial

Officer

or

another

senior

officer

designated

by

the

Chief

Executive

Officer

or

Chief

Financial Officer for such purpose. See also “Lobbying

Activities and Political and Charitable Contributions” below.

Board Appointments

An employee may

not sit

on the board

of a

publicly-traded company or

other entity (other

than the Company

and its

affiliates)

without

the

permission

of

a senior

officer

or

in

the

case

of

a

senior

officer,

the

Chief

Executive

Officer.

Membership

on

charitable or community

boards does not

require pre-approval but such

activity must not interfere

with duties and

obligations

to the Company and must not reflect negatively on the Company.

An employee

who sits

on the board

of a company

or other

entity (other

than the

Company and

its affiliates)

must abstain

from voting on any matter that directly or indirectly concerns the Company or would be contrary to the Company’s interests

or would give the appearance or perception of a conflict of interest.

  • 3 -

Personal Gain

Employees,

officers

and

directors

must

not

directly

or

indirectly

use

their

status

or

position

with

the

Company

to

obtain

personal

gain

in

any

manner,

including

from

those

doing

or

seeking

to

do

business

with

the

Company.

Applicable

law

provides that

if personal

financial benefit

is improperly

gained by

an employee,

officer or

director directly

or indirectly, through

a spouse or child or a relative sharing the same residence as the

individual, as a result of his employment or position or by

the

use or

misuse

of

the

Company’s

property

or

of

information

that

is confidential

to

the

Company’s

business,

then the

employee, officer or director must account to

the Company for any benefit received.

Company Confidential Information

Employees,

officers

and

directors

must

safeguard

the

Company’s

Confidential

Information.

Confidential

Information

includes, but is not limited

to, trade secrets, know

how, records,

data, plans, strategies, processes,

business opportunities

and ideas relating to present

and contemplated products and services

and financial affairs of the

Company,

its customers,

its suppliers and/or employees, as well as information relating

to cybersecurity risks and incidents, which information is not

generally known to the public.

Employees, officers

and directors

are prohibited

from disclosing Confidential

Information or

other information

which might

impair the Company’s competitive position or which might

violate the private rights of individuals, enterprises or

institutions

without

appropriate

authorization

in

accordance

with

the

Company’s

Disclosure,

Confidentiality

and

Trading

Policy,

and

must

take

the

appropriate

steps

to

protect

such

information.

The

above

rules also

apply

to

confidential

information

of

a

Company customer or

supplier (or prospective customer

or supplier). These confidentiality

obligations continue even

after

an individual’s service as an employee, officer

or director of the Company has ceased.

If

the

decision

is

made

to

disclose

Confidential

Information

to

any

person

or

entity

outside

of

the

Company

(such

as

a

potential

vendor

or

business

partner),

it

should

be

done

only

after

appropriate

confidentiality

agreements

are

executed.

These agreements must document the need to maintain confidentiality of the Confidential

Information that is disclosed and

copies of all

confidentiality agreements must be

forwarded to a

senior officer. The amount of

Confidential Information shared

with any

person or

entity outside

of the

Company should,

in any

case, be

kept to

the minimum

necessary to

address the

applicable business need.

All employees, officers and directors

must also adhere to the Company’s

policies, procedures, and rules on confidentiality,

disclosure and

insider trading

as set

out in

the Company’s

Disclosure, Confidentiality

and Trading

Policy.

A copy

of such

policy is

available on

the Company’s

intranet, but

it may

also be

obtained from

a senior

officer.

Nothing in

such policy

or

this

Code

restricts

an

employee

from

reporting

potential

violations

of

law

to

securities

regulators

or

other

governmental

agencies

or self-regulatory

authorities

without

notice

or permission

from

the

Company,

or providing

disclosures

that are

protected or required under

applicable whistleblower laws and

on

behalf

of

the

Company,

or

benefits

to

other

persons

Recording of Transactions and

Reporting of Financial Information

The integrity of the Company’s record keeping

and reporting systems shall be maintained at

all times, as these systems are

required for the Company to meet its financial, legal and other

business obligations.

Employees must document

and record all transactions

in accordance with

the Company’s

internal control procedures

and

in compliance

with all

applicable accounting

principles, laws,

rules and regulations,

and employees

with responsibility

for

reporting

financial

information

must provide

information

that is

accurate,

complete,

objective, timely

and

understandable

and that complies

with all applicable

laws relating to

the recording and

disclosure of financial

information. Employees

and

managers are

forbidden to

use, authorize,

or condone

the use

of "off-the-books"

record-keeping or

any other

device that

could be utilized

to distort records

or reports

of the Company’s

true operating results

and financial conditions.

Employees

must not fraudulently

influence, coerce,

manipulate or

mislead any

independent public

or certified

accountant engaged

in

the performance of an audit,

review, compilation or other service

with respect to the financial statements for the purpose of

rendering such financial statements misleading.

Use of Written Agreements; No Side Deals or Side

Letters

The

Company

documents

business

transactions

with

full

and

complete

written

agreements

that

set

out

the

terms

and

conditions of

the agreement

and understandings

between the

parties. No

new agreement

can be

created, or

an existing

agreement

modified,

without

approval

of

a

senior

officer.

All

new

agreements

should

also

be

reviewed

by

the

relevant

functional areas, including finance, as the terms and

conditions of the agreement may affect how the

Company records and

reports

the

transaction

for

accounting

or

other

purposes.

No

oral

contracts,

informal

letters

of

understanding

or

intent,

“handshake deals” or side

letters are permitted. Where

the Company has developed

standard written agreements and

other

provisions, schedules,

riders

and appendices,

Company employees

must use

these standard

forms except

to the

extent

that changes are authorized by a senior officer.

Records Retention and Destruction

Legal and regulatory practice requires

the retention of certain records, such

as certain tax, personnel health

and safety, and

financial records,

for various

periods of

time and

employees, officers

and directors

are required

to comply

with Company

  • 7 -

controls for

the retention

and timely

destruction of

records. In

addition, when

litigation or

a governmental

investigation or

audit

is

pending

or

imminent,

relevant

records

must

not

be

altered

or

destroyed

until

the

matter

is

closed.

Alteration

or

destruction of records in a legal or governmental proceeding

may constitute a criminal offense.

A senior

officer

will notify

employees when

records have

been placed

on a

“legal hold”.

Such records

cannot be

altered,

destroyed,

deleted

or modified

in any

manner

for the

duration of

the “legal

hold”.

Questions regarding

records

retention

should be addressed

to a senior

officer,

particularly if any

litigation, investigation, inquiry

or administrative action

involving

the Company or any of its employees, suppliers or customers

is pending or threatened.

Cybersecurity

Cyber-attacks may be

carried out by

third parties or

insiders using

techniques that

range from highly

sophisticated efforts

to electronically

circumvent

network security

or overwhelm

websites

to

more traditional

intelligence

gathering

and social

engineering aimed at obtaining

information necessary to

gain access. In addition,

third parties may attempt

to fraudulently

induce employees

or customers

to, or

the

Company’s

employees

or customers

themselves

may,

disclose information

in

order

to

gain

access

to

the

Company’s

data

or

its

customers’

information

and

potentially

use

such

data

or

information

improperly.

Employees

must

not

engage

in

or

otherwise

aid,

assist

or

ignore

any

potential

or

actual

cyber-attacks

or

other

cyber

incidents

or

otherwise

exploit

any

cybersecurity

vulnerabilities

of

the

Company,

and

employees

must

report

any

such

threatened or actual cyber-attacks or cybersecurity vulnerabilities.

Ethical Competitive Practices and Third-Party Intellectual

Property

The Company competes vigorously and creatively in its business activities, but does so in a fair, lawful and ethical manner.

Employees must

not use

improper or

illegal means

of gathering

information about

competitors or

other third

parties, and

must not exchange information

or agree with competitors

in connection with pricing

or other matters that

are prohibited by

applicable law.

Theft

or illegal

entry

and electronic

eavesdropping

are unacceptable

means of

searching

for competitive

intelligence. Employees

must neither offer

a bribe or

a gift in

exchange for a

competitor’s information

nor otherwise solicit

information from current or former employees of a competitor. Employees, officers and directors of the Company must also

not knowingly use or bring onto

the Company’s computer systems intellectual property belonging to third parties

without the

applicable third party’s consent, a license or

other legal right.

Crime and Money-Laundering Prevention

The

Company

is

committed

to

comply

fully

with

all

applicable

anti-money

laundering

laws,

both

domestically

and

internationally.

The Company will conduct

business only with reputable customers

who are involved in legitimate

business

activities and whose funds

are derived from legitimate

sources. All employees

are to take reasonable

steps to ensure that

the Company does not aid

or take part in any

illegal activities or accept

payments that have been

identified as a means

of

laundering money.

DEALINGS WITH PERSONS OUTSIDE THE COMPANY

The

honesty

and

integrity

of

those

who

represent

the

Company

must

underlie

all

of

the

Company’s

relationships

with

persons outside the Company.

Dealing with Public Officials

As a general

matter, all

dealings between

employees, officers

and directors of

the Company and

public officials

are to be

conducted

in

a

manner

that

will

not

compromise

the

integrity

or

impugn

the

reputation

of

the

Company,

its

employees,

officers

or

directors

or

any

public

official.

The

Company

specifically

prohibits

bribery

of

public

officials

and

third

parties

anywhere

in

the

world

and

requires

compliance

with

all

applicable

laws

in

the

countries

in

which

the

Company

does

business, including, without limitation, Canada’s Corruption

of Foreign Public Officials Act (“

CFPOA

”) and the U.S. Foreign

Corrupt Practices

Act (“

FCPA

”), which prohibit

bribery and corruption.

This legislation

also requires

the Company to

keep

accurate books and records and maintain effective internal controls.

The CFPOA and the FCPA

each have a broad scope,

and apply to

the activities of

the Company and

activities carried out

through its subsidiaries

and affiliates

anywhere in the

world.

Even the appearance of impropriety in

dealing with public officials is improper and unacceptable. Any participation,

whether

directly or indirectly, in any bribes, kickbacks, improper profit-sharing arrangements, illegal gratuities, indirect contributions,

improper

inducements,

“facilitation

payments”

or

similar

payments

to

any

public

official

is

expressly

forbidden,

notwithstanding that they might further the business interests of the Company and notwithstanding that such practices may

  • 8 -

be considered to be a way of “doing business” or necessary

in a particular country in question,

including where the making

small “facilitation

payments”

to foreign

public officials

to secure

a routine

business

service or

have routine

administrative

actions performed by public officials is local custom. Furthermore, certain

laws, such as the CFPOA, apply to dealings with

foreign public officials in Canada and in the official

’s own state.

It is the

Company’s policy that no payments

or offers to make payments

whatsoever, regardless of amount or purpose, shall

be

made

either

directly

or

through

third

parties

to

officials

or

employees

of

government

agencies

or

instrumentalities

(including government

monopolies) without

an express

authorization

from a

senior

officer

following consultation

with

the

appropriate

compliance

personnel.

Any

approved

arrangements

must

be

documented

in

accordance

with

the

Company

legal and accounting requirements and ethical business

practices.

The Company

may hire

former public

officials

from time

to time,

but because

of the

restrictions that

applicable laws

can

place on

such

arrangements

in certain

circumstances,

employees,

officers

and

directors

must first

consult

with a

senior

officer

prior to

hiring

a current

or former

public official,

or their

family

members

and the

Company

will

not

hire any

such

official if he or she is participating in a matter reasonably

regarded as involving the Company’s

interests.

For

purposes

of

this

Code,

a

“public

official”

should

be

interpreted

broadly

and

includes

any

official

or

employee

of

a

government

or

of

a

department,

organization

or

agency

of

a

government

(or

any

department,

organization

or

agency

thereof); any employee of any company owned or controlled by a

government; any official who holds a legislative or judicial

position; any official of a public

international organization; any political

party or official of a political

party; any candidate for

political office;

and any

person or

firm acting

in an

official

capacity,

including for,

or on

behalf of,

any of

the

following:

a

government, a

department

or agency

of a

government,

a company

owned or

controlled by

a government,

a legislator,

a

judicial officer, a public

international organization, or any political party.

The Company and

its representatives

will not engage

in or undertake

lobbying activities

as defined under

applicable laws

unless all requirements

under such

applicable laws

have been

satisfied and

the prior

express approval

of a

senior officer

has been obtained following consultation with appropriate

compliance personnel.

Dealing with the Media and Communications Generally

The Company is committed

to providing, as appropriate,

full and prompt disclosure

to the public of

material developments

and events. However,

all media, public and investor relations and

communications are to be co-ordinated

through a senior

officer and the Investor Relations, as applicable, in accordance with the Company’s Disclosure, Confidentiality and Trading

Policy and applicable

laws. Employees

should not comment

on any inquiry

from the media,

no matter

how innocuous the

inquiry may appear. Any employee who is asked by the media or otherwise for a statement or to give a

presentation should

explain that he or she is subject

to this Code and the Disclosure,

Confidentiality and Trading

Policy and refer the matter

to

a senior officer.

Dealings with Suppliers, Agents and Representatives

Selection of suppliers to the Company will be based on merit

after due consideration of alternatives. The Company will only

deal

with

suppliers

who

comply

with

applicable

legal

requirements

(including

any

applicable

regulations

requiring,

for

example, the conduct of background checks) and

the Company’s standards relating to, among other things,

labor, including

not

using

child

or

forced

labor,

environment,

health

and

safety,

intellectual

property

rights

and

refraining

from

improper

payments.

Confidential

information

received

from

a

supplier

shall

be

treated

as

if

it

were

the

Company’s

Confidential

Information (see “Conflicts of Interest and Disclosure Issues

– Company Confidential Information”).

The Company will

enter into representation

agreements only with

companies or persons

believed to have

a record of

and

commitment

to

integrity.

Efforts

will

be

taken

by

the

Company

and

its

employees

to

ensure

that

agents,

consultants,

independent contractors,

representatives and

suppliers are

aware of this

Code. A senior

officer should

be contacted

prior

to

retaining

any

individual

who

is

to

act

as

an

agent,

consultant,

independent

contractor

or

representative,

and

such

individual should be retained only pursuant to a written

contract that has been approved by a senior officer

.

In

cases

where

an

agent,

consultant,

independent

contractor,

or

a

representative

is

engaged

to

provide

services
