NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS

MARCH 31, 2021

Note 1. TheCompany

Cellectis S.A. (hereinafter “Cellectis” or “we”) is a limited liability company (“société anonyme”) registered and domiciled in Paris, France. We are a clinical-stage biotechnological company, employing our core proprietary technologies to develop best-in-class products in the field of immuno-oncology.

Our product candidates, based on gene-edited T-cells that express chimeric antigen receptors, or CARs, seek to harness the power of the immune system to target and eradicate cancer cells. Our gene-editing technologies allow us to create allogeneic CAR T-cells, meaning they are derived from healthy donors rather than the patients themselves. Our gene editing expertise also enables us to develop product candidates that feature additional safety and efficacy attributes, including control properties designed to prevent them from attacking healthy tissues, to enable them to tolerate standard oncology treatments, and to equip them to resist mechanisms that inhibit immune-system activity. In addition to our focus on immuno-oncology, we are exploring the use of our gene-editing technologies in other therapeutic applications, as well as through our subsidiary, Calyxt, to deliver plant-based innovations and solutions with substantial disruption potential across multiple industries.

Cellectis S.A., Cellectis, Inc., Cellectis Biologics Inc. (which was incorporated on January 18, 2019) and Calyxt, Inc. are sometimes referred to as a consolidated group of companies as the “Group.”

COVID-19 Update

While implementing health and safety measures in response to the COVID-19 pandemic, we continued to advance our proprietary allogeneic CAR T-cell programs during the three months ended March 31, 2021.

Although the COVID-19 pandemic has slowed the enrolment of new patients, Cellectis continued to enroll patients in its AMELI-01, BALLI-01 and MELANI-01 clinical trials during this first quarter of 2021, and each of the trials currently continues to progress through its respective dose levels.

Despite the increasing availability of COVID-19 vaccines, the COVID-19 pandemic and government actions to contain it continue to result in significant disruptions to various public and commercial activities. With respect to clinical trials for both our proprietary allogeneic CAR T-cell programs and programs conducted by commercial partners, enrollment of new patients and the ability to conduct patient follow-up is expected to continue to be impacted by the COVID-19 pandemic. The exact timing of delays and overall impact of the COVID-19 pandemic to our business, preclinical studies, clinical trials and manufacturing facility construction and initial production activity is currently unknown, and we are monitoring the pandemic as it continues to evolve.

At Calyxt, during the first quarter of 2021, the COVID-19 pandemic did not have a material impact on operations. However, a resurgence of the COVID-19 pandemic, governmental response measures, and resulting disruptions could adversely affect Calyxt’s operations and results.

The overall impact to Cellectis’ and Calyxt’s businesses will be dependent on future developments, which are highly uncertain and difficult to predict.

Note 2. Accounting principles

2.1 Basis for preparation

The Interim Consolidated Financial Statements of Cellectis as of, and for the three-month period ended, March 31, 2021 were approved by our Board of Directors on May 6, 2021.

The Interim Consolidated Financial Statements are presented in U.S. dollars. See Note 2.2.

The Interim Consolidated Financial Statements as of, and for the three-month period ended March 31, 2021 have been prepared in accordance with International Accounting Standard (“IAS”) 34 Interim Financial Reporting, as issued by the International Accounting Standards Board (“IASB”).

The Interim Consolidated Financial Statements as of and for the three-month period ended March 31, 2021 have been prepared using the same accounting policies and methods as those applied for the year ended December 31, 2020, except as described below related to the new or amended accounting standards applied.

IFRS include International Financial Reporting Standards (“IFRS”), International Accounting Standards (“the IAS”), as well as the interpretations issued by the Standards Interpretation Committee (“the SIC”), and the International Financial Reporting Interpretations Committee (“IFRIC”).

Application of new or amended accounting standards or new amendments

The following pronouncements and related amendments have been adopted by us from January 1, 2021 but had no significant impact on the Interim Consolidated Financial Statements:

•	Interest Rate Benchmark Reform – Phase 2: Amendments to IFRS 9, IAS 39, IFRS 7, IFRS 4 and IFRS 16. The<br>amendments provide temporary reliefs which address the financial reporting effects when an interbank offered rate (IBOR) is replaced with an alternative nearly risk-free interest rate (RFR).

Accounting standards, interpretations and amendments issued but not yet effective

The following pronouncements and related amendments are applicable for accounting periods beginning after January 1, 2021. We do not anticipate that the adoption of these pronouncements and amendments will have a material impact on our results of operations, financial position or cash flows:

•	Amendments to IFRS 16 Leases:<br>Covid-19-Related Rent Concessions beyond 30 June 2021(issued on 31 March 2021)
•	Amendments to IAS 37 – Onerous Contracts: Cost of Fulfilling a Contract (Effective for the accounting<br>periods as of January 1, 2022)
---	---
•	Amendments to IAS 16 – Property, Plant and Equipment: Proceeds before Intended Use (Effective for the<br>accounting periods as of January 1, 2022)
---	---
•	Amendments to IFRS 3 – Reference to the Conceptual Framework (Effective for the accounting periods as of<br>January 1, 2022)
---	---

2.2 Currency of the financial statements

The Interim Consolidated Financial Statements are presented in U.S. dollars, which differs from the functional currency of Cellectis, which is the euro. We believe that this presentation enhances the comparability with peers, which primarily present their financial statements in U.S. dollars.

All financial information (unless indicated otherwise) is presented in thousands of U.S. dollars.

The statements of financial position of consolidated entities having a functional currency different from the U.S. dollar are translated into U.S. dollars at the closing exchange rate (spot exchange rate at the statement of financial position date) and the statements of operations, statements of comprehensive income (loss) and statements of cash flows of such consolidated entities are translated at the average period to date exchange rate. The resulting translation adjustments are included in equity under the caption “Accumulated other comprehensive income (loss)” in the Statements of Changes in Shareholders’ Equity.

2.3 Consolidated entities andnon-controlling interests

Accounting policy

We control all the legal entities included in the consolidation. An investor controls an investee when the investor is exposed to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the investee. Control requires power, exposure to variability of returns and a linkage between the two.

To have power, the investor needs to have existing rights that give it the current ability to direct the relevant activities that significantly affect the investee’s returns.

In order to ascertain control, potential voting rights which are substantial are taken into consideration.

Consolidation of a subsidiary begins when the Group obtains control over the subsidiary and ceases when the Group loses control of the subsidiary.

All intra-Group assets and liabilities, equity, income, expenses and cash flows relating to transactions between members of the Group are eliminated in full in the consolidation.

Consolidated entities

For the three-month periods ended March 31, 2021 and March 31, 2020, the consolidated group of companies (sometimes referred to as the “Group”) includes Cellectis S.A., Cellectis, Inc., Cellectis Biologics, Inc., which was incorporated on January 18, 2019, and Calyxt.

As of March 31, 2021, Cellectis S.A. owns 100% of Cellectis, Inc., which owns 100% of Cellectis Biologics, Inc., and approximately 64.5% of Calyxt’s outstanding shares of common stock.

Non-controlling interests

Non-controlling shareholders held a 35.3% interest in Calyxt as of December 31, 2020 and a 35.5% interest in Calyxt as of March 31, 2021. These non-controlling interests were generated during the initial public offering of Calyxt and a subsequent follow-on offering, as well as through vesting and exercises of equity awards.

Revenues related to licenses include royalties received under our various license agreements.

Reportable segments are identified as components of the Group that have discrete financial information available for evaluation by the Chief Operating Decision Maker (“CODM”), for purposes of performance assessment and resource allocation.

For the three-month period ended March 31, 2021, Cellectis’ CODM is composed of:

•	The Chief Executive Officer;
•	The Executive Vice President Strategic Initiatives;
---	---
•	The Executive Vice President Global Quality (until April 2021);
---	---
•	The Senior Vice President Europe Technical Operations;
---	---
•	The Senior Vice President of US Manufacturing;
---	---
•	The Chief Scientific Officer;
---	---
•	The Chief Financial Officer;
---	---
•	The General Counsel;
---	---
•	The Chief Business Officer;
---	---
•	The Chief Regulatory & Compliance Officer;
---	---
•	The Chief Medical Officer; and
---	---
•	The Chief Human Resources Officer.
---	---

We view our operations and manage our business in two operating and reportable segments that are engaged in the following activities:

• Therapeutics: This segment is focused on the development (i) of products in the field of immuno-oncology and (ii) of novel therapies outside immuno-oncology to treat other human diseases. This approach is based on our gene editing and Chimeric Antigen Receptors (“CARs”) technologies. All these activities are supported by Cellectis S.A., Cellectis, Inc. and Cellectis Biologics, Inc. The operations of Cellectis S.A., the parent company, are presented entirely in the Therapeutics segment which also comprises research and development, management and support functions.

• Plants: This segment is focused on delivering plant-based innovations and solutions with substantial disruption potential across multiple industries. It corresponds to the activity of our U.S.-based majority-owned subsidiary, Calyxt, which is currently based in Roseville, Minnesota.

There are inter-segment transactions between the two reportable segments, including allocation of corporate general and administrative expenses by Cellectis S.A. and allocation of research and development expenses to the reportable segments.

With respect to corporate general and administrative expenses, Cellectis S.A. has provided Calyxt, with general sales and administrative functions, accounting and finance functions, investor

relations, intellectual property, legal advice, human resources, communication and information technology under a Management Services Agreement. Effective with the end of the third quarter 2019, Calyxt has internalized nearly all of the services previously provided by Cellectis under this agreement. Under the Management Services Agreement, Cellectis S.A. charges Calyxt, in euros at cost plus a mark-up ranging between zero to 10%, depending on the nature of the service. Amounts due to Cellectis S.A. pursuant to inter-segment transactions bear interest at a rate of the 12-month Euribor plus 5% per annum.

The intersegment revenues represent the transactions between segments. Intra-segment transactions are eliminated within a segment’s results and intersegment transactions are eliminated in consolidation as well as in key performance indicators by reportable segment.

Information related to each reportable segment is set out below. Segment revenues and other income, Research and development expenses, Selling, general and administrative expenses, and Cost of revenue and other operating income and expenses, and Adjusted net income (loss) attributable to shareholders of Cellectis (which does not include non-cash stock-based compensation expense) are used by the CODM for purposes of making decisions about allocating resources to the segments and assessing their performance. The CODM does not review any asset or liability information by segment or by region.

Adjusted Net Income (Loss) attributable to shareholders of Cellectis S.A. is not a measure calculated in accordance with IFRS. Because Adjusted Net Income (Loss) attributable to shareholders of Cellectis excludes Non-cash stock-based compensation expense—a non-cash expense, our management believes that this financial measure, when considered together with our IFRS financial statements, can enhance an overall understanding of Cellectis’ financial performance. Moreover, our management views the Company’s operations, and manages its business, based, in part, on this financial measure.

The net income (loss) by segment includes the impact of the operations between segments while the intra-segment operations are eliminated.

No indicator of impairment has been identified for any intangible or tangible assets in the CGUs at the end of the three-month period ended March 31, 2021.

Note 5. Right-of-use assets

Accounting policy

Lease contractsrecognition

Lease contracts, as defined by IFRS 16 “Leases”, are recorded in the statement of consolidated financial position, which leads to the recognition of:

•	an asset representing a right of use of the asset leased during the lease term of the contract “right-of-use”; and
•	a liability related to the payment obligation “lease debt”.
---	---

Measurement of the right-of use asset

At the commencement date, the right-of-use asset is measured at cost and comprises:

•	the amount of the initial measurement of the lease liability, to which is added, if applicable, any lease<br>payments made at or before the commencement date, less any lease incentives received;
•	where relevant, any initial direct costs incurred by the lessee for the conclusion of the contract. These are<br>incremental costs which would not have been incurred if the contract had not been concluded; and
---	---
•	estimated costs for restoration of the leased asset according to the terms of the contract.<br>
---	---

Following the initial recognition, the right-of-use asset must be depreciated over the useful life of the underlying assets as lease term for the rental component.

Measurement of the lease liability

At the commencement date, the lease liability is recognized for an amount equal to the present value of the lease payments over the lease term.

Amounts involved in the measurement of the lease liability are:

•	fixed payments (including in-substance fixed payments; meaning that even<br>if they are variable in form, they are in-substance unavoidable);
•	variable lease payments that depend on an index or a rate, initially measured using the index or the rate in<br>force at the lease commencement date; amounts expected to be payable by the lessee under residual value guarantees; and
---	---
•	payments of penalties for terminating the lease, if the lease term reflects the lessee exercising an option to<br>terminate the lease.
---	---

The lease liability is subsequently measured based on a process similar to the amortized cost method using the discount rate:

•	the liability is increased by the accrued interests resulting from the discounting of the lease liability, at the<br>beginning of the lease period; and
•	payments made are deducted.
---	---

The interest cost for the period as well as variable payments, not taken into account in the initial measurement of the lease liability and incurred over the relevant period are recognized as costs.

In addition, the lease liability may be remeasured in the following situations:

•	the occurrence of a change in the lease term or a modification related to the assessment of the reasonably<br>certain nature (or not) of the exercise of an option,
•	a remeasurement linked to residual value guarantees, or
---	---
•	the occurrence of an adjustment to the rates and indices according to which the rents are calculated when rent<br>adjustments occur.
---	---

COVID-19-Related RentConcessions

On May 28, 2020, the IASB issued “COVID-19-Related Rent Concessions”, an amendment to IFRS 16. The amendment, which is applicable from June 1, 2020 allows lessees not to account for rent concessions as lease modifications if they are a direct consequence of COVID-19 and meet certain conditions. The practical expedient has been applied by the Group to all rent concessions that meet the conditions in IFRS 16.46B.

The amount recognised in profit or loss for the reporting period to reflect changes in lease payments that arise from rent concessions to which the Group has applied the practical expedient in IFRS 16.46A is immaterial.

Main contracts applicable

Based on its analysis, the Group has identified lease contracts according to the standard concerning office buildings, laboratories, production facilities and storage facilities.

For purposes of IFRS 16, the lease term reflects the Group’s reasonable expectation of the period during which the underlying asset will be used.

The discount rate used to calculate the lease debt is determined, for each portfolio of assets, according to the incremental borrowing rate at the contract date.

The incremental borrowing rate is the rate of interest that a lessee would have to pay to borrow over a similar term, and with a similar security, the funds necessary to obtain an asset of a similar value to the right-of-use asset in a similar economic environment.

The rental charges relating to short term and low value lease remains classified as leases expenses in operating expenses.

Details of Right-of-useassets

IFRS 16 “Leases” is applicable for annual periods beginning on or after January 1, 2019. The consequence of the application of this standard is to recognize a right of use and lease liability on the Statement of financial position.

The breakdown of right-of-use assets is as follows:

As of March 31, 2021, no assets have been pledged as security for financial liabilities. There is no restriction on title of property, plant and equipment.

For the three-month period ended March 31, 2021, we continued our investments in research and development equipment in both the United States of America and France. The addition in tangible assets reflects improvements of Calyxt and Cellectis sites for $1.6 million and other equipment for $1.4 million ($0.9 million of technical equipment and $0.4 million of other equipment).

Assets under construction as of March 31, 2021 primarily relates to Cellectis’ new raw materials manufacturing facility and offices in Paris ($2.3 million), and a new commercial manufacturing facility in Raleigh, North Carolina ($42.5 million), and the balance relates to capital expenditure in Cellectis’ New York office and in the Plants Segment. The assets put into service in 2021 amount to $0.6 million for Cellectis for the Paris manufacturing facility and offices, to $3.5 million for Cellectis for the Raleigh manufacturing facility and to $1.0 million for Calyxt.

Note 7. Non-current financial assets

On February 12, 2021, Cellectis entered into an agreement with Cytovia Therapeutics, Inc. (“the Cytovia agreement”). The consideration to Cellectis includes a convertible note for $15 million issued by Cytovia to Cellectis upon the signature of the contract (which may be settled in cash or converted to equity of Cytovia under certain conditions). This convertible note does not bear interest. As of March 31, 2021, management has determined that the fair value of the note approximates its carrying value. The fair value measurement of the convertible note is categorized within Level 1. No credit loss is expected over this convertible note.

As of March 31, 2021, the other non-current financial liabilities are mainly composed of the following elements:

•	a financial liability of $3.3 million related to an equipment rental agreement at our Raleigh good<br>manufacturing practices (“GMP”) facility, which will be reclassified to lease debt when the equipment is delivered or accepted by Cellectis; and
•	Cellectis’ obtention in 2020 of a $1.4 million loan to finance leasehold improvement at our location in<br>New-York.
---	---

PPP loan corresponds to Calyxt’s obtention of a $1.5 million paycheck protection program (PPP) loan under the U.S. Coronavirus Aid, Relief and Economic Security (CARES) Act, for which Calyxt had applied for forgiveness on October 21, 2020. On April 8, 2021, Calyxt was notified by the Small Business Administration, which administers the PPP loan program, that the full amount of the PPP loan had been forgiven.

State Guaranteed loan « PGE » corresponds to includes Cellectis’ obtention of an €18.5 million (or $21.7 million using exchange rate as of March 31, 2021) loan from a bank syndicate formed with HSBC, Société Générale, Banque Palatine and Bpifrance in the form of a state-guaranteed loan (Prêt Garanti par l’Etat) (the “PGE“). Initiated by the French Government to support companies during the COVID-19 crisis, the PGE is a bank loan with a fixed interest rate ranging from 0.25% to 2.35%. After an initial interest-only term of two years, the loan will be amortized over up to four years at the option of the Company. The French government guarantees 90% of the borrowed amount.

Accruals for personnel are related to annual bonuses, vacations accruals and social expenses on stock options. The decrease in accruals for personnel related expenses between December 31, 2020 and March 31, 2021 is mainly explained by yearly bonus payments which occurred in February 2021.

The decrease in other between December 31, 2020 and March 31, 2021, is mainly driven by fixed assets accruals.

Note 14. Non-cash stock-based compensation

14.1 Detail of Cellectis equity awards

Holders of vested Cellectis stock options and warrants are entitled to exercise such options and warrants to purchase Cellectis ordinary shares at a fixed exercise price established at the time such options and warrants are granted during their useful life.

For stock options and warrants, we estimate the fair value of each option on the grant date or other measurement date if applicable using a Black-Scholes option-pricing model, which requires us to make predictive assumptions regarding future stock price volatility, employee exercise behavior, dividend yield, and the forfeiture rate. We estimate our future stock price volatility based on Cellectis historical closing share prices over the expected term period. Our expected term represents the period of time that options granted are expected to be outstanding determined using the simplified method. The risk-free interest rate for periods during the expected term of the options is based on the French government securities with maturities similar to the expected term of the options in effect at the time of grant. We have never declared or paid any cash dividends and do not presently plan to pay cash dividends in the foreseeable future. Consequently, we used an expected dividend yield of zero. Options may be priced at 100 percent or more of the fair market value on the date of grant, and generally vest over four years after the date of grant. Options generally expire within ten years after the date of grant.

These free shares have been granted to a large number of our employees.<br>

The fair value of free shares corresponds to the grant date share fair value.

We have never declared or paid any cash dividends and do not presently plan to pay cash dividends in the foreseeable future. Consequently, we used an expected dividend yield of zero in determining fair value.

Share-based compensation expense related to free shares awards was $1.0 million and $19 thousand for the three-month periods March 31, 2021 and 2020, respectively.

On March 5, 2021, the Board of Directors decided to grant 330,041 free shares under the Amended Second Free Share 2018 Plan. As the employees and the members of the CODM accept the grant after March 31, 2021, the related share-based compensation expense was not recognized during the three-month period ended March 31, 2021.

Calyxt estimates the fair value of each option on the grant date or other measurement date if applicable using a Black-Scholes option-pricing model, which requires Calyxt to make predictive assumptions regarding future stock price volatility, employee exercise behavior, dividend yield, and the forfeiture rate. Calyxt estimates its future stock price volatility using the historical volatility of comparable public companies over the expected term of the option.

Calyxt’s expected term represents the period of time that options granted are expected to be outstanding determined using the simplified method.

The risk-free interest rate for periods during the expected term of the options is based on the U.S. Treasury zero-coupon yield curve in effect at the time of grant.

Calyxt has not paid and does not expect to pay dividends for the foreseeable future.

Options may be priced at 100 percent or more of the fair market value on the date of grant, and generally vest over six years after the date of grant. Options generally expire within ten years after the date of grant. Certain awards granted before Calyxt’s IPO contained accelerated vesting provisions if certain events occurred as defined in the option agreement.

The fair value of restricted stock units corresponds to the grant date share fair value.

Calyxt has not paid and does not expect to pay dividends for the foreseeable future.

Share-based compensation expense related to restricted stock units awards was a gain of $0.9 million due to options forfeiture or expiration, compared to an expense of $0.3 million for the three-months periods ended March 31, 2021 and 2020, respectively.

Performance Stock Unit

In June 2019, Calyxt granted performance stock units, which carry a market condition based on Calyxt share price. These awards contain a continuous service period of three years, the performance period, from the date of grant, followed by a restricted period of two years if the shares are issued following the performance period during which the grantee is required to provide continuous service and the awarded shares must be held by the grantee until the end of the period. The number of shares of common stock delivered following the performance period depends upon the change in Calyxt share price during the performance period. Calyxt granted a targeted 311,667 performance stock units. The performance criteria allow for the actual payout to be between zero and 120 percent of target. The fair value of the performance stock units and the assumptions used for the Monte Carlo simulation were as follows:

Date of grant	06/28/2019
Estimated fair values of performance stock units granted	$	7.06

Obligations under the terms of lease agreements

Almost all of our lease agreement are accounted for under IFRS 16 and thereby are presented in the statement of consolidated financial position. The commitments related to operating leases exempted from IFRS 16 application are immaterial.

Obligations under the terms of licenseagreements

We have entered into various license agreements with third parties that subject us to certain fixed license fees, as well as fees based on future events, such as research and sales milestones.

We also have collaboration agreements whereby we are obligated to pay royalties and milestone payments based on future events that are uncertain and therefore they are not included in the table above.

Obligations under theterms of manufacturing agreements

We have manufacturing agreements whereby we are obligated to pay for services rendered in the next 12 months regarding our products UCART123, UCARTCS1 and UCART22.

Obligations under the terms of Clinical & Research agreements

We have entered into clinical and research agreements where we are obligated to pay for services to be provided regarding our research collaboration agreements, clinical trials and translational research projects.

Obligations under the terms of Constructionagreements

We have entered into a construction agreement regarding our manufacturing facility based in Raleigh, North Carolina, where we committed to pay for construction work.

Obligations under the terms of other agreements

Calyxt has entered into seed and grain production agreements (Forward Purchase Contracts) with seed producers and growers. Calyxt announced in December 2020 that Archer Daniels Midland has committed to purchase over four million bushels of Calyxt’s grain, which includes all the 2020 soybean crop, which Calyxt will purchase from growers between January 1, 2021 and August 31, 2021. Calyxt expects to sell that grain throughout 2021 and no later than December 31, 2021. Calyxt expects to sell the remaining grain to Archer Daniels Midland at market prices, and as a result, Calyxt will continue to hedge fixed price grain inventories and fixed price Forward Purchase Contracts to mitigate the risk changing market prices may have on Calyxt’s margins.

As of March 31, 2021, Calyxt has non cancelable commitments to purchase grain and seed from growers at dates throughout 2021 aggregating $11.7 million based on current commodity futures market prices, other payments to growers, and estimated yields per acre. This commitment is not recorded in the consolidated financial statements because Calyxt has not taken delivery of the seed or grain as of March 31, 2021.

The seed contracts often require Calyxt to pay prices for the seed produced at an exchange-traded price of grain plus a premium with the seed grower having the option to fix their price with Calyxt throughout the term of the agreement.

The grower contracts are linked to a commodity futures market prices with the grain grower having the option to fix their price with Calyxt throughout the term of the agreement. The grain grower contracts allow for delivery of grain to Calyxt at harvest if so specified when the agreement is executed, otherwise delivery occurs on a date that Calyxt elects through August 31 of the following year.

In all periods presented, we considered Forward Purchase Contracts as normal purchases and not derivatives. Any mark-to-market gains or losses associated with those contracts were reflected in inventory upon our purchase of the underlying grain

As of March 31, 2021, Calyxt has $3.0 million of unrealized commodity derivative losses from hedging contracts sold to convert their fixed price grain inventories and fixed price Forward Purchase Contracts to floating prices. As of March 31, 2021, Calyxt held commodity contracts with a notional amount of $10.4 million.

Note 18. Subsequent events

On April 9, 2021, Cellectis announced that it has completed sales of approximately $47 million in gross proceeds of American Depositary Shares (“ADS”) pursuant to the Company’s At-the-market (“ATM”) program established on March 29, 2021 (the “ATM Sales”), through Jefferies LLC (“Jefferies”), acting as sales agent. Each ADS represents one ordinary share of the Company. In the ATM Sales, an aggregate of 2,415,630 new ADSs and the same number of underlying new ordinary shares have been issued to existing and new investors at an at-the-market price of $19.50 per new ADS.

On April 8, 2021, Calyxt was notified by the SBA that the full amount of their Paycheck Protection Program loan had been forgiven.

Item 2. Management’s Discussion & Analysis of FinancialCondition and Results of Operations

Overview

We are a clinical stage biotechnological company, employing our core proprietary technologies to develop best-in-class products in the field of immuno-oncology. Our product candidates, based on gene-edited T-cells that express chimeric antigen receptors, or CARs, seek to harness the power of the immune system to target and eradicate cancers. We believe that CAR-based immunotherapy is one of the most promising areas of cancer research, representing a new paradigm for cancer treatment. We are designing next-generation immunotherapies that are based on gene-edited CAR T-cells. Our gene-editing technologies allow us to create allogeneic CAR T-cells, meaning they are derived from healthy donors rather than the patients themselves. We believe that the allogeneic production of CAR T-cells will allow us to develop cost-effective, “off-the-shelf” products and are capable of being stored and distributed worldwide. Our gene-editing expertise also enables us to develop product candidates that feature additional safety and efficacy attributes, including control properties designed to prevent them from attacking healthy tissues, to enable them to tolerate standard oncology treatments, and to equip them to resist mechanisms that inhibit immune-system activity. Together with our focus on immuno-oncology, we are exploring the use of our gene-editing technologies in other therapeutic applications, and in addition to product candidate development for oncology may also pursue additional investigational new drug (IND) filings outside of oncology.

We currently conduct our operations through two business segments, Therapeutics and Plants. Our Therapeutics segment is mainly focused on the development of products in the field of immuno-oncology. Our Plants segment, carried out through our 64.5% (as of March 31, 2021) ownership in Calyxt, focuses on plant-based innovations and solutions with substantial disruption potential across multiple industries and tailored to specific downstream issues, while leveraging partners and licensees to manage commercialization and the associated costs and risks.

Since our inception in early 2000, we have devoted substantially all of our financial resources to research and development efforts. Our current research and development focuses primarily on our CAR T-cell immunotherapy product candidates, including preparing to conduct clinical studies of our product candidates, providing general and administrative support for these operations and protecting our intellectual property.

We do not have any therapeutics products approved for sale and have not generated any revenues from therapeutic product sales.

For the three-month period ended March 31, 2021, we derived all of our Therapeutics revenues from the receipt of a convertible note (to be settled in cash or equity of Cytovia, depending on certain conditions) in consideration for a “right-to-use” license from the Cytovia licensing arrangement, a milestone reached as part of our collaboration with Allogene and royalties on licensed technologies.

As of March 31, 2021, we were eligible to receive potential development and commercial milestone payments pursuant to (i) the License, Collaboration and Commercialization Agreement dated March 6, 2019 between Servier and Cellectis, as amended on March 4, 2020 (the “Servier License Agreement”) of up to $410 million and (ii) the License Agreement dated March 7, 2019 between Allogene and Cellectis (the “Allogene License Agremeent) of up to $2.8 billion. Under the Allogene License Agreement, we are eligible to receive tiered royalties on annual worldwide net sales of any products that are commercialized by Allogene that contain or incorporate, are made using or are claimed or covered by, our intellectual property licensed to Allogene under the Allogene License Agreement at rates in the high single-digit percentages. Under the Servier License Agreement, we are

eligible to receive flat low double-digit royalties based on annual net sales of commercialized products as well as a low double-digit royalty on certain development milestone payments received by Servier. For the three-month period ended March 31, 2021 no revenue was recorded other than the one related Allogene and Cytovia’s agreements.

We are also party to a research and development alliance with MD Anderson Cancer Center pursuant to which we are currently collaborating on translational activities related to UCARTCS1. Under this agreement, we fund these translational activities.

We are currently sponsoring clinical studies with respect to three proprietary Cellectis product candidates at eight (8) sites for the AMELI-01 Study, at five (5) sites for the BALLI-01 Study, and at two (2) sites for the MELANI-01 Study, as follows:

•	The AMELI-01 Study is a Phase 1 dose-escalation clinical trial designed<br>to evaluate the safety, expansion, persistence and clinical activities of UCART123 in-patients with relapsed or refractory acute myeloid leukemia (r/r AML). The AMELI-01<br>Study is currently open for patient recruitment at MD Anderson Cancer Center (Houston, Texas), H. Lee Moffitt Cancer Center & Research Institute (Tampa, Florida), Dana Farber Cancer Institute (Boston, Massachussetts), New York Presbyterian<br>/ Weill Cornell College of Cornell University (New York, New York), Northwestern University (Chicago, Illinois), University of Miami (Miami, Florida) the University of Pennsylvania (Philadelphia, Pennsylvania), and University of California (San<br>Francisco, California). We are enrolling patients in the second dose level of the AMELI-01 Study with lymphodepletion regimen including an anti-CD52 monoclonal antibody.
•	The BALLI-01 Study is a Phase 1/2 dose-escalation and expansion clinical<br>trial designed to evaluate the safety, expansion, persistence and clinical activities of UCART22 in-patients with relapsed or refractory acute lymphoblastic leukemia (r/r ALL). The BALLI-01 Study is currently open to patient recruitment at New York Presbyterian / Weill Cornell College of Cornell University (New York, New York), the University of Chicago (Chicago, Illinois), MD Anderson Cancer<br>Center (Houston, Texas), University of California Los Angeles (Los Angeles, California) and Dana Farber Cancer Institute (Boston, Massachussetts). We are enrolling patients in the second dose level of the<br>BALLI-01 Study with lymphodepletion regimen including an anti-CD52 monoclonal antibody.
---	---
•	The MELANI-01 Study is a Phase 1 dose-escalation clinical trial designed<br>to evaluate the safety, expansion, persistence and clinical activities of UCARTCS1 in patients with relapsed or refractory multiple myeloma (r/r MM). The MELANI-01 Study is currently open to patient<br>recruitment at Hackensack Meridian Health (Hackensack, New Jersey) and MD Anderson Cancer Center (Houston, Texas).

COVID-19 Update

While implementing health and safety measures, we continued to advance our proprietary allogeneic CAR T-cell programs during the three months ended March 31, 2021.

Although the COVID-19 pandemic has slowed the enrollment of new patients, Cellectis continued to enroll patients in its AMELI-01, BALLI-01 and MELANI-01 clinical trials during the first quarter of 2021, and each of the trials currently continues to progress through its respective dose levels.

Despite the increasing availability of COVID-19 vaccines, the COVID-19 pandemic and government actions to contain it continue to result in significant disruptions to various public and commercial activities. With respect to clinical trials for both our proprietary allogeneic CAR T-cell programs and programs conducted by commercial partners, enrollment of new patients and the ability to conduct patient follow-up is expected to be impacted by the COVID-19 pandemic. The exact timing of delays and overall impact of the COVID-19 pandemic to our business, preclinical studies, clinical trials and manufacturing facility construction and initial production activity is currently unknown, and we are monitoring the pandemic as it continues to evolve.

At Calyxt, during the first quarter of 2021, the COVID-19 pandemic did not have a material impact on Calyxt’s operations. However, a resurgence of the COVID-19 pandemic, governmental response measures, and resulting disruptions could adversely affect Calyxt’s operations and results.

The overall impact to Cellectis’ and Calyxt’s businesses will be dependent on future developments, which are highly uncertain and difficult to predict. See Part II, Item 3.D. “Risk Factor” of our report on Form 20-F.

Key events ofthe three-month period ended March 31, 2021

Since the beginning of 2021, Cellectis has made the following key achievements:

•	On February 16, 2021, Cytovia Therapeutics, Inc., a biopharmaceutical company developing allogeneic “off-the-shelf” gene-edited Natural Killer (NK) and Chimeric Antigen Receptor (CAR)-NK cells derived from induced pluripotent<br>stem cells (iPSCs), and Cellectis announced that they entered into a strategic research and development collaboration to develop TALEN^®^ gene-edited iPSC NK and<br>CAR-NK cells. The financial terms of the partnership include up to $760 million of development, regulatory, and sales milestones from Cytovia to Cellectis for the first 5 TALEN^®^ gene-edited iPSC-derived NK products (“partnership products”). Cellectis will also receive single-digit royalty payments on the net sales of all partnered products commercialized by<br>Cytovia. Cellectis obtained a convertible note as consideration for a “right-to-use” license granted to Cytovia and will receive an equity stake of<br>$15 million in Cytovia stock or a cash payment of $15 million in settlement of the convertible note if certain conditions are not met by December 31, 2021, as well as an option to invest in future financing rounds.<br>
•	On March 4 and 5, 2021, the Board of Directors decided to grant 924,520 stock-options under the 2018 stock<br>option plan, and 330,041 free shares under the Amended Second Free Share 2018 Plan.

Financial Operations Overview

We have incurred net losses in nearly each year since our inception. Substantially all of our net losses resulted from costs incurred in connection with our development programs and from selling, general and administrative expenses associated with our operations. As we continue our intensive research and development programs, we expect to continue to incur significant expenses and may again incur operating losses in future periods. We anticipate that such expenses will increase substantially if and as we:

•	progress our sponsored clinical trials AMELI-01, BALLI-01 and MELANI-01, and initiate additional clinical trials for our other owned product candidates;
•	continue to advance the research and development of our current and future immuno-oncology product candidates;<br>
---	---
•	initiate additional clinical studies for, or additional pre-clinical<br>development of, our immuno-oncology product candidates;
---	---
•	advance research and development efforts for additional product candidates outside of oncology;<br>
---	---
•	further develop and refine the manufacturing process for our immuno-oncology product candidates;<br>
---	---
•	complete construction of (in the case of our Raleigh facility), bring online, and commence production at our in-house manufacturing facilities and change or add additional manufacturers or suppliers of biological materials to support our in-house manufacturing capabilities;<br>
---	---
•	seek regulatory and marketing approvals for our product candidates, if any, that successfully complete<br>development;
---	---
•	establish a sales, marketing and distribution infrastructure to commercialize any products for which we may<br>obtain marketing approval;
---	---
•	seek to identify and validate additional product candidates;
---	---
•	acquire or in-license other product candidates, technologies or<br>biological material;
---	---
•	make milestone or other payments under any in-license agreements;<br>
---	---
•	maintain, protect and expand our intellectual property portfolio;
---	---
•	seek to attract and retain new and existing skilled personnel;
---	---
•	create additional infrastructure to support our operations as a public company;
---	---
•	continue, through Calyxt, to advance research and development of future plant-based innovations and solutions,<br>including the initiation and advancement of additional field trials, compliance with applicable regulatory regimes, and the acquisition of germplasm and other biological materials, and to execute upon the deployment of such innovations through<br>Calyxt’s trait development and licensing go-to-market strategy; and
---	---
•	experience any delays or encounter issues with any of the above.
---	---

We do not expect to generate material revenues from sales of our therapeutic product candidates unless and until we successfully complete development of, and obtain marketing approval for, one or more of our product candidates, which we expect will take a number of years and is subject to significant uncertainty. Accordingly, we anticipate that we will need to raise additional capital prior to completing clinical development of any of our therapeutic product candidates. Until such time that we can generate substantial revenues from sales of our product candidates, if ever, we expect to finance our operating activities through a combination of milestone payments received pursuant to our collaboration and license agreements, equity offerings, debt financings, government or other third-party funding and collaborations, and licensing arrangements. However, we may be unable to raise additional funds or enter into such arrangements when needed on favorable terms, or at all, which would have a negative impact on our financial condition and could force us to delay, limit, reduce or

terminate our development programs or commercialization efforts or grant to others rights to develop or market product candidates that we would otherwise prefer to develop and market ourselves. Failure to receive additional funding could cause us to cease operations, in part or in full.

Our interim consolidated financial statements for the three months ended March 31, 2021 have been prepared in accordance with International Financial Reporting Standards, or IFRS, as issued by the International Accounting Standards Board, or IASB.

Results of Operations

Comparison for the three-month periods ended March 31, 2020 and 2021

Revenues.

	For the three-month period ended<br>March 31,				% change
	2020		2021		2021 vs 2020
Collaboration agreements		47,027		20,565		-56.3	%
Other revenues		3,102		5,036		62.4	%
Revenues	****	50,128	****	25,601	****	-48.9	%

The decrease in revenues of $24.5 million between the three-month periods ended March 31, 2020 and 2021 primarily reflects a decrease of revenue pursuant to our collaboration agreements of $26.5 million, mainly due to a $27.6 million upfront payment received in March 2020 and the recognition of $19.4 million of deferred upfront and milestone payments already received on released targets in each case in connection with the amendment signed in March 2020 to our collaboration agreement with Servier, while revenue related to collaboration agreements in the first quarter of 2021 consists of the recognition of $15.0 million convertible note obtained as consideration for a “right-to-use” license granted to Cytovia and a $5.1 million Allogene milestone. The increase in other revenues of $1.9 million relates to higher high oleic soybean seed grain sales at Calyxt.

Other income		(69	)		2		-103.0	%
Other income	****	1,778	****	****	2,365	****	33.0	%

The increase in other income of $0.6 million between the three-month periods ended March 31, 2020 and 2021 mainly reflects an increase of $0.5 million in research tax credits, due to higher research and development purchases and external expenses during the three-month period ended March 31, 2021 that are eligible for the tax credit.

Cost of revenue

	For the three-month period ended<br>March 31,						% change
	2020			2021			2021 vs 2020
Cost of goods sold		(3,884	)		(7,331	)		88.8	%
Royalty expenses		(716	)		(814	)		13.7	%
Cost of revenue	****	(4,600	)	****	(8,145	)	****	77.1	%

The increase in cost of goods sold of $3.5 million between the three-month period ended March 31, 2020 and 2021 is driven by higher volumes of product sold by Calyxt in 2021 compared to 2020, higher average prices paid for Calyxt’s grain as a result of increases in commodity market prices for soybeans, and $0.2 million of unrealized commodity derivative losses at Calyxt from hedging contracts sold to convert its fixed price grain inventory and fixed price Forward Purchase Contracts to floating prices to link them to market, consistent with Calyxt expects to sell the grain. These increases were partially offset by the benefits resulting from the advancement of Calyxt’s soybean product line go-to-market strategy.

Research and development expenses.

	For the three-month period endedMarch 31,						% change
	2020			2021			2021 vs 2020
Personnel expenses		(9,089	)		(13,111	)		44.2	%

Research and development expenses	****	(20,724	)	****	(31,004	)	****	49.6	%

Between the three-month periods ended March 31, 2020 and 2021, research and development expenses increased by $10.3 million. Personnel expenses increased by $4.0 million from $9.1 million in 2020 to $13.1 million in 2021 primarily due to a $4.2 million increase in wages and salaries as a result of increased R&D headcount in the therapeutic segment and a $0.8 million increase in social charges on stock option grants which were partially offset by a $0.9 million decrease in non-cash stock-based compensation expense. Purchases, external expenses and other increased by $6.3 million from $11.6 million in 2020 to $17.9 million in 2021 of which $6.1 million relates to the therapeutic segment.

Selling, general and administrative expenses.

	For the three-month period endedMarch 31,						% change
	2020			2021			2021 vs 2020
Personnel expenses		(6,958	)		(4,782	)		-31.3	%

Selling, general and administrative expenses	****	(12,146	)	****	(8,779	)	****	-27.7	%

Between the three-month periods ended March 2020 and 2021, the decrease in selling, general and administrative expenses of $3.4 million primarily reflects a $2.2 million decrease in personnel expenses from $7.0 million in 2020 to $4.8 million mainly due to a $3.9 million decrease in non-cash stock-based compensation expense mainly explained by the favorable impact of the recapture of Calyxt’s CEO non-cash stock-based from the forfeiture of certain of his unvested stock options, restricted stock units, and performance stock units following his departure. partly offset by a $1.3 million increase in wages and salaries and a $0.3 million decrease in social charges on stock option grants. Purchases, external expenses and other decreased by $1.2 million from $5.2 million in 2020 to $4.0 million in 2021.

Net Financial gain (loss)	****	2,190	****	****	4,561	****	****	108.3	%

The increase in financial income of $2.1 million between the three-month periods ended March 31, 2020 and 2021 was mainly attributable to an increase of the foreign exchange gain of $2.5 million (from a $2.6 million gain in 2020 to a $5.4 million gain in 2021) and to the fair value adjustment for $0.2 million partially offset by to the decrease of interest received from financial investments of $0.6 million.

The decrease in financial expenses of $0.2 million between the three-month periods ended March 31, 2020 and 2021 was mainly attributable to $0.6 million decrease in foreign exchange loss (from a $0.7 million loss in 2020 to a $0.1 million loss in 2021) partially offset by the increase in financial expenses related to the increase in lease debt for $0.3 million.

During the three-month periods ended March 31, 2021, we recorded $3.5 million in loss attributable to non-controlling interests. During the three-month period ended March 31, 2020, we also recorded $3.5 million in loss attributable to non-controlling interests. ****

Segment Results

Information related to each of our reportable segments is set out below. Segment revenues and Other income, Research and development expenses, Selling, general and administrative expenses, and Royalties and other operating income and expenses, and Adjusted net income (loss) attributable to shareholders of Cellectis (which does not include non-cash stock-based expense) are used by the CODM to measure performance of each segment. The CODM does not review any asset or liability information by segment or by region.

Adjusted Net Income (Loss) attributable to shareholders of Cellectis is not a measure calculated in accordance with IFRS. Because Adjusted Net Income (Loss) attributable to shareholders of Cellectis excludes Non-cash stock based compensation expense—a non-cash expense, we believe that this financial measure, when considered together with our IFRS financial statements, can enhance an overall understanding of Cellectis’ financial performance. Moreover, our management views the Company’s operations, and manages its business, based, in part, on this financial measure.

There are inter-segment transactions between the two reportable segments, including the allocation of corporate general and administrative expenses by Cellectis S.A. and the allocation of research and development expenses among the reportable segments. With respect to corporate general and administrative expenses, Cellectis S.A. has provided Calyxt with general sales and administrative functions, accounting and finance functions, investor relations, intellectual property, legal advice, human resources, communication and information technology pursuant to a Management Services Agreement. Under the Management Services Agreement, Cellectis S.A. charges Calyxt in euros at cost plus a mark-up ranging between zero to 10%, depending on the nature of the service. Amounts due to Cellectis S.A. pursuant to inter-segment transactions bear interest at a rate of 12-month Euribor plus 5% per annum. Effective with the end of the third quarter of 2019, Calyxt has internalized nearly all of the services Cellectis provided.

The following table summarizes segment revenues and segment operating profit (loss) for the three-month periods ended period 2020 and 2021:

We allocate the share-based compensation to the share-related entity, (rather than the entity related to the employee that benefited from such compensation), considering that the share-based compensation is linked to entity’s performance. Consequently, all share-based compensation based on Cellectis shares is charged in the Therapeutics segment, even if some Calyxt employees are included in a Cellectis stock-option plan.

Therapeutics segment

External revenues and other income in our Therapeutics segment decreased by $26.6 million, from $49.5 million for the three-month period ended March 31, 2020, to $23.0 million for the three-month period ended March 31, 2021. The decrease was primarily due to a decrease of $26.5 million in collaboration agreement revenues, as described in sections “Revenues” and “Other income” under “Results of Operations” for the consolidated Group.

The increase in total operating expenses of $8.8 million from the three-month period ended March 31, 2020 to the three-month period ended March 31, 2021 resulted primarily from (i) higher purchases, external expenses and other of $5.3 million, higher personnel expenses of $3.6 million attributable to (ii) an increase of $4.2 million in personnel wages and salaries and (iii) an increase of $1.1 million in social charges on stock option grants partially offset by (i) a decrease of $1.7 million in non-cash stock-based compensation expenses, and (ii) a decrease of $0.1 million in royalty expenses.

Operating loss before tax for our Therapeutics segment increased by $35.4 million from the three-month period ended March 31, 2020 to the three-month period ended March 31, 2021.

Adjusted net loss attributable to shareholders of Cellectis for our Therapeutics segment decreased by $34.8 million from the three-month period ended March 31, 2020 to the three-month period ended March 31, 2021.

Plantssegment

External revenues and other income in our Plants segment increased by $2.6 million from $2.4 million for the three-month period ended March 31, 2020 to $5.0 million for the three-month period ended March 31, 2021 due Calyxt’s high oleic soybean seed grain sales..

The increase in total operating expenses of $1.5 million from three-month period ended March 31, 2020 to the three-month period ended March 31, 2021 resulted primarily from an increase in Calyxt’s activities, which contributed to (i) an increase in cost of goods sold of $3.5 million and (ii) an increase of $1.3 million in personnel wages and salaries mainly related to former CEO’s departure costs partially offset by (i) a decrease of $3.0 million in non-cash stock-based compensation expenses mainly explained by the favorable impact of the recapture of Calyxt’s CEO non-cash stock-based from the forfeiture of certain of his unvested stock options, restricted stock units, and performance stock units following his departure and (ii) a decrease of $0.2 million in purchases, external expenses and other.

Operating loss before tax for our Plants segment decreased by $1.1 million from the three-month period ended March 31, 2020 to the three-month period ended March 31, 2021.

Adjusted net loss attributable to shareholders of Cellectis for our Plants segment increased by $0.6 million from the three-month period ended March 31, 2020 to the three-month period ended March 31, 2021.

Liquidity and Capital Resources

Introduction

We have incurred losses and cumulative negative cash flows from operations since our inception in 2000, and we anticipate that we will continue to incur losses for at least the next several years. We expect that our research and development and selling, general and administrative expenses will continue to increase and, as a result, we will need additional capital to fund our operations, which we may raise through a combination of equity offerings, debt financings, other third-party funding, marketing and distribution arrangements and other collaborations, strategic alliances and licensing arrangements.

We have funded our operations since inception primarily through private and public offerings of our equity securities, grant revenues, payments received under patent licenses, reimbursements of research tax credit claims and payments under our collaboration agreements with Allogene and Servier.

Our ordinary shares have been traded on the Euronext Growth market of Euronext in Paris since February 7, 2007 and our ADSs have traded on the Nasdaq Global Market in New York since March 30, 2015.

Liquidity management

As of March 31, 2021, we had current financial assets and cash and cash equivalents of $225.9 million comprising cash and cash equivalents of $207.5 million and current financial assets of $18.4 million which include $15.4 million of current restricted cash and $3.0 million of short-term investments at Calyxt. Long term restricted cash amounts to $5.3 million and is classified in Other non-current financial assets.

Cash in excess of immediate requirements is invested in accordance with our investment policy, primarily with a view to liquidity and capital preservation. Currently, our cash and cash equivalents are held in bank accounts, money market funds, fixed bank deposits primarily in France. The portion of cash and cash equivalents denominated in U.S. dollars is $121.8 million as of March 31, 2021. Current financial assets denominated in U.S. Dollars amounted to $18.4 million as of March 31, 2021.

On March 9, 2021, we commenced an At-the-Market (ATM) program, which allows us to offer and sell, from time to time, ordinary shares in the form of American Depositary Shares (ADS ) (each representing one ordinary share of the Company) to certain eligible investors. We are not obligated to sell ADSs pursuant to the ATM program, and offers and sales occur only at our discretion and on our instructions and at at-the- market prices. The ATM program provides for a total maximum gross amount of $125 million. On April 9, 2021, Cellectis completed an initial sale under the ATM program for gross proceeds of $47 million (equivalent to 40 million euros).

Historical Changes in Cash Flows

The table below summarizes our sources and uses of cash for the three-month periods ended March 31, 2020 and 2021:

All values are in US Dollars.

For the three-month period ended March 31, 2021, our net cash flows used in operating activities are mainly due to Cellectis cash payments of $17.3 million to suppliers, wages and social expenses of $17.1 million, Calyxt operating payments of $8.9 million, partially offset by $1.0 million of licensing revenue at Cellectis, and $1.4 million of taxes and other fees.

For the three-month period ended March 31, 2020, our net cash flows provided by operating activities are mainly due to Cellectis cash payments of $11.5 million to suppliers, wages and social expenses of $9.4 million, and Calyxt operating payments of $12.4 million, offset by $32.9 million of payments received from Servier pursuant to our collaboration agreement, $1.0 million of payments received from licenses, and $0.6 million of interest received as well as other variances.

Operating capital requirements

Our cash consumption is driven by our internal operational activities, as well as our outsourced activities, including the pre-clinical research and development activities, manufacturing and

technology transfer expenses payable to CMO providers, costs and expenses associated with our clinical trials, including payments to clinical research centers, CROs involved in the clinical trials, and third-parties providing logistics and testing services, as well as costs and expenses relating to construction and bringing online of our in-house manufacturing facilities. In addition, we incur significant annual payment and royalty expenses related to our in-licensing agreements with different parties including Institut Pasteur (expired in 2020), LifeTechnologies and University of Minnesota. We also incur substantial expenses related to audit, legal, regulatory and tax related services associated with our public company obligations in the United States and our continued compliance with applicable U.S. exchange listing and SEC requirements.

To date, we have not generated any revenues from therapeutic product sales. In addition to our cash generated by operations (including payments under our collaboration agreements), we have funded our operations primarily through private and public offerings of our equity securities, grant revenues, payments received under intellectual property licenses, and reimbursements of research tax credits.

We do not know when, or if, we will generate any revenues from therapeutic product sales. We do not expect to generate significant revenues from product sales unless and until we obtain regulatory approval of and commercialize one of our current or future therapeutic product candidates.

In August 2020, Calyxt announced a transition to a capital-efficient business model comprising three differentiated go-to-market strategies. As part of the transition of strategy, Calyxt stopped processing soybeans into oil and meal and restructured its personnel involved in soybean processing and downstream product sales. In the fourth quarter of 2020, Calyxt announced having contracted to sell all its 2020 grain production (approximately four million bushels) of high oleic soybean to Archer Daniels Midland (ADM). To date, Calyxt has sold more than 50%of the 2020 grain crop to ADM with the remaining grain projected to be sold throughout 2021 under existing contracts. While Calyxt will opportunistically engage in arrangements under each available go-to-market strategy, it has determined to pursue trait development and licensing with respect to all of the products currently under development at Calyxt. This primary focus on trait development and licensing provides a capital-efficient, lower-cost, and highly scalable approach. Calyxt has not yet generated substantial third-party licensing revenue, and we do not know when, or if, Calyxt will generate substantial revenues from the implementation of its primary go-to-market strategy.

We are subject to all risks incident in the development of new gene therapy products, and we may encounter unforeseen expenses, difficulties, complications, delays and other unknown factors that may adversely affect our business. We are also subject to all risks incident in the development of new plant-based innovations and solutions, and we may encounter unforeseen expenses, difficulties, complications, delays and other unknown factors that may adversely affect our business.

We anticipate that we will need additional funding in connection with our continuing operations, including for the further development of our existing product candidates and to pursue other development activities related to additional product candidates.

We believe that the consolidated cash, cash equivalents, current financial assets and restricted cash position of Calyxt as of March 31, 2021 will be sufficient to fund their operations into the second half of 2022 while amounts attributable to Cellectis after taking into consideration $45.5 million of net equity proceeds raised pursuant to the Company’s “At the Market” (ATM) program in April 2021 will be sufficient to fund our operations into early 2023.

Until we can generate a sufficient amount of revenues from our products, if ever, we expect to finance a portion of future cash needs through public or private equity or debt offerings. Additional capital may not be available on reasonable terms, if at all. If we are unable to raise additional capital in sufficient amounts or on terms acceptable to us, we may have to significantly delay, scale back or discontinue the development or commercialization of one or more of our product candidates. If we raise additional funds through the issuance of additional debt or equity securities, it could result in

dilution to our existing shareholders, increased fixed payment obligations and these securities may have rights senior to those of our ordinary shares. If we incur indebtedness, we could become subject to covenants that would restrict our operations and potentially impair our competitiveness, such as limitations on our ability to incur additional debt, limitations on our ability to acquire, sell or license intellectual property rights and other operating restrictions that could adversely impact our ability to conduct our business. Any of these events could significantly harm our business, financial condition and prospects.

Our assessment of the period of time through which our and Calyxt’s financial resources will be adequate to support our operations is a forward-looking statement and involves risks and uncertainties, and actual results could vary as a result of a number of factors. This estimate takes into account our projected cash flow from operations (including payments we expect to receive pursuant to our strategic licensing agreements) and government funding of research programs, as well as Calyxt’s anticipated cash burn rate, anticipated expense reduction efforts, and its expectations regarding an effective advancement of its go-to-market strategy and anticipated cash receipts from its product development efforts with partners. We have based this estimate on assumptions that may prove to be wrong, and we could use our available capital resources sooner than we currently expect. Our future funding requirements, both near and long-term, will depend on many factors, including, but not limited to:

•	the initiation, progress, timing, costs and results of pre-clinical and<br>clinical studies for our product candidates;
•	the capacity of manufacturing our products in France and in the United States;
---	---
•	the outcome, timing and cost of regulatory approvals by U.S. and non-U.S.<br>regulatory authorities, including the possibility that regulatory authorities will require that we perform more studies than those that we currently expect;
---	---
•	the ability of our product candidates to progress through clinical development successfully;<br>
---	---
•	the cost of filing, prosecuting, defending and enforcing any patent claims and other intellectual property<br>rights;
---	---
•	our need to expand our research and development activities;
---	---
•	our need and ability to hire additional personnel;
---	---
•	our need to implement additional infrastructure and internal systems, including manufacturing processes for our<br>product candidates;
---	---
•	the effect of competing technological and market developments;
---	---
•	the cost of establishing sales, marketing and distribution capabilities for any products for which we may receive<br>regulatory approval; and
---	---
•	progress, timing and success of Calyxt’s business, including its advancement of successful field trials and<br>its ability to successfully deploy products and technologies under its primary go-to-market strategy.
---	---

If we cannot expand our operations or otherwise capitalize on our business opportunities because we lack sufficient capital, our business, financial condition and results of operations could be materially adversely affected.

Off-Balance Sheet Arrangements.

As of March 31, 2021, we do not have any off-balance sheet arrangements as defined under SEC rules.
