1. DESCRIPTION OF THE BUSINESS AND BASIS OF PRESENTATION

Description of the Business

Montrose Environmental Group, Inc. (“Montrose” or the “Company”) is a corporation formed on November 2013, under the laws of the State of Delaware. The Company has approximately 110 offices across the United States, Canada, Australia and Europe and approximately 3,380 employees as of June 30, 2024.

Montrose is an environmental services company serving the recurring environmental needs of a diverse client base, including Fortune 500 companies and federal, state and local governments through the following three segments:

Assessment, Permitting and Response segment provides scientific advisory and consulting services to support environmental assessments, environmental emergency response and recovery, toxicology consulting and environmental audits and permits for current operations, facility upgrades, new projects, decommissioning projects and development projects. The Company works closely with clients to navigate the regulatory process at the local, state, provincial and federal levels, identify the potential environmental and political impacts of their decisions and develop practical mitigation approaches, as needed. In addition to environmental toxicology, and given the Company's expertise in helping businesses plan for and respond to disruptions, the Company's scientists and response teams have helped clients navigate their preparation for and response to emergency response situations.

Measurement and Analysis segment is one of the largest providers of environmental testing and laboratory services in North America. The Company's highly credentialed teams test and analyze air, water and soil to determine concentrations of contaminants, as well as the toxicological impact of contaminants on flora, fauna and human health. The Company's offerings include source and ambient air testing and monitoring, leak detection, and advanced multi-media laboratory services, including air, soil, stormwater, wastewater and drinking water analysis.

Remediation and Reuse segment provides clients with engineering, design, and implementation services, primarily to treat contaminated water, remove contaminants from soil or create biogas from waste. The Company's team, including engineers, scientists and consultants, provides these services to assist clients in designing solutions, managing products and mitigating environmental risks and liabilities at their locations. The Company does not own the properties or facilities at which it implements these projects or the underlying liabilities, nor does the Company own material amounts of the equipment used in projects.

Basis of Presentation

The unaudited condensed consolidated financial statements include the operations of the Company and its wholly-owned subsidiaries. These unaudited condensed consolidated financial statements are presented in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) and have been prepared pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) that permit reduced disclosure for interim periods. The unaudited condensed consolidated financial statements include all accounts of the Company and, in the opinion of management, include all recurring adjustments and normal accruals necessary for a fair statement of the Company’s financial position, results of operations and cash flows for the dates and periods presented. These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited financial statements as of and for the year ended December 31, 2023. Results for interim periods are not necessarily indicative of the results to be expected during the remainder of the current year or for any future period. All intercompany transactions, accounts and profits, have been eliminated in the unaudited condensed consolidated financial statements.

Within the unaudited condensed consolidated financial statements certain amounts in the prior period have been reclassified to conform with current period presentation. The Company reclassified $1.8 million of provision for bad debt, $0.9 million of fair value changes, $1.5 million of deferred income taxes, and $1.1 million of other activities to other operating activities, net, in the condensed consolidated statements of cash flows for the six months ended June 30, 2023. The Company disaggregated 130,115 shares or $3.2 million of common stock issued for quarter ended June 30, 2023, and 427,631 shares or $8.2 million of common stock issued for quarter ended March 31, 2024 to separate line items on the condensed consolidated statements of convertible and redeemable series A-2 preferred stock and stockholders’ equity. These changes had no effect on the Company's results of operations or financial position.

2. SUMMARY OF NEW ACCOUNTING PRONOUNCEMENTS

Recently Adopted Accounting Pronouncements

In November 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standard Update ("ASU") 2023-07, Improvements to Reportable Segment Disclosures. The amendments improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. In addition, the amendments enhance interim disclosure requirements, clarify circumstances in which an entity can disclose multiple segment measures of profit or loss, provide new segment disclosure requirements for entities with a single reportable segment, and contain other disclosure requirements. The purpose of the amendments is to enable investors to better understand an entity’s overall performance and assess potential future cash flows. ASU 2023-07 is effective for the Company's fiscal year beginning January 1, 2024 and requires the use of a retrospective approach to all prior periods presented. The Company adopted the standard on January 1, 2024, and plans to adopt the standard for interim periods beginning January 1, 2025. The Company is evaluating the potential impact of its adoption of ASU 2023-07 on the Company's audited Consolidated Financial Statements but does not anticipate that such an adoption will have a material impact.

Recently Issued Accounting Pronouncements Not Yet Adopted

In August 2023, the FASB issued ASU 2023-05, under which an entity that qualifies as either a joint venture or a corporate joint venture is required to apply a new basis of accounting upon the formation of the joint venture. Specifically, the ASU provides that a joint venture or a corporate joint venture must initially measure its assets and liabilities at fair value on the formation date. The amendments in ASU 2023-05 are effective for all joint ventures within the ASU’s scope that are formed on or after January 1, 2025. Early adoption is permitted. The Company is currently evaluating the impact of the adoption of the standard on its consolidated financial statements.

In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures, which improves the transparency of income tax disclosures by requiring consistent categories and greater disaggregation of information in the rate reconciliation and income taxes paid disaggregated by jurisdiction. It also includes certain other amendments to improve the effectiveness of income tax disclosures. ASU 2023-09 is effective for the Company beginning January 1, 2025 and allows the use of a prospective or retrospective approach. The Company is currently evaluating the impact of the adoption of the standard on its consolidated financial statements.

3. REVENUES AND ACCOUNTS RECEIVABLE

The Company’s main revenue sources derive from the following revenue streams:

Assessment, Permitting and Response Revenues—Assessment, Permitting and Response revenues are generated from multidisciplinary environmental consulting services. The majority of the contracts are fixed-price or time and material based.

Measurement and Analysis Revenues—Measurement and Analysis revenues are generated from emissions sampling, testing and reporting services, leak detection services, ambient air monitoring services and laboratory testing services. The majority of the contracts are fixed-price or time-and-materials based.

Remediation and Reuse Revenues—Remediation and Reuse revenues are generated from engineering, design, implementation and operating and maintenance (“O&M”) services primarily to treat contaminated water, remove contaminants from soil or create biogas from waste. Engineering, design and implementation contracts are predominantly fixed-fee and time-and-materials based. Services on the majority of O&M contracts are provided under long-term fixed-fee contracts.

Disaggregation of Revenue—The Company disaggregates revenue by its operating segments. The Company believes disaggregating revenue into these categories achieves the disclosure objectives to depict how the nature, amount, and uncertainty of revenue and cash flows are affected by economic factors. Disaggregated revenue disclosures are provided in Note 19.

Contract Balances—The Company presents contract balances for unbilled receivables (contract assets), as well as customer advances, deposits and deferred revenue (contract liabilities) within contract assets and accounts payable and other accrued expenses, respectively, on the unaudited condensed consolidated statements of financial position. Amounts are generally billed at periodic intervals (e.g. weekly, bi-weekly or monthly) as work progresses in accordance with agreed-upon contractual terms. The Company utilizes the practical expedient to not adjust the promised amount of consideration for the effects of a significant financing component as the period between when the Company transfers services to a customer and when the customer pays for those services is one year or less. Amounts recorded as unbilled receivables are generally for services the Company is not entitled to bill based on the passage of time. Under certain contracts, billing occurs subsequent to revenue recognition, resulting in contract assets. The Company sometimes receives advances or deposits from customers before revenue is recognized, resulting in contract liabilities. 6

The following table presents the Company’s contract balances:

June 30, December 31,
2024 2023
Contract assets $ 73,224 $ 51,629
Contract liabilities 13,284 8,132

Contract assets acquired through business acquisitions amounted to $2.4 million and $2.2 million as of June 30, 2024 and December 31, 2023, respectively. No material contract liabilities were acquired through business acquisitions as of June 30, 2024 and December 31, 2023.

Revenue recognized during the three and six months ended June 30, 2024, included in the contract liabilities balance at the beginning of the year was $4.8 million and $9.3 million, respectively. The revenue recognized from the contract liabilities consisted of the Company satisfying performance obligations during the normal course of business.

Remaining Unsatisfied Performance Obligations—Remaining unsatisfied performance obligations represent the total dollar value of work to be performed on fixed fee contracts awarded primarily within our soil remediation, water treatment, and renewable business lines. The amount of remaining unsatisfied performance obligations increases with new contracts or additions to existing contracts and decreases as revenue is recognized on existing contracts. Contracts are included in the amount of remaining unsatisfied performance obligations when an enforceable agreement has been reached. As of June 30, 2024 and December 31, 2023, the estimated revenue expected to be recognized in the future related to performance obligations that are unsatisfied was approximately $80.5 million and $81.9 million, respectively. As of June 30, 2024, the Company expected to recognize approximately $60.5 million of this amount as revenue within a year and $20.0 million the year after.

Accounts Receivable, Net

—The Company extends non-interest-bearing trade credit to its customers in the ordinary course of business. Accounts receivable, net consisted of the following:

June 30, 2024 December 31, 2023
Accounts receivable, invoiced $ 136,972 $ 115,064
Accounts receivable, other 1,481 20
Allowance for doubtful accounts (2,784 ) (2,724 )
Accounts receivable, net $ 135,669 $ 112,360

The Company had one and zero customer that exceeded 10.0% of its gross receivables as of June 30, 2024 and December 31, 2023, respectively. For the three and six months ended June 30, 2024, the Company had no customer who accounted for more than 10% of revenue. During the three and six months ended June 30, 2023, the Company had one customer who accounted for 12.3% and 10.4% of revenue, respectively.

6. LEASES

Leases are classified as either finance leases or operating leases based on criteria in ASC 842. The Company has finance leases for its vehicle and equipment leases and operating leases for its real estate space and office equipment leases. The Company’s operating and finance leases generally have original lease terms between 1 year and 15 years, and in some instances include one or more options to renew. The Company includes options to extend the lease term if the options are reasonably certain of being exercised. The Company currently considers some of its renewal options to be reasonably certain to be exercised. Some leases also include early termination options, which can be exercised under specific conditions. The Company does not have material residual value guarantees or restrictive covenants associated with its leases.

Finance and operating lease assets represent the right to use an underlying asset for the lease term, and finance and operating lease liabilities represent the obligation to make lease payments arising from the lease.

The Company calculates the present value of its finance and operating leases using an estimated incremental borrowing rate (“IBR”), which requires judgment. For real estate operating leases, the Company estimates the IBR based on prevailing market rates for collateralized debt in a similar economic environment with similar payment terms and maturity dates commensurate with the terms of the lease. For all other leases, the Company estimates the IBR based on the stated interest rate on the contract. Since many of the inputs used to calculate the rate implicit in the leases are not readily determinable from the lessee’s perspective, the Company does not use the implicit interest rate.

Certain leases contain variable payments, these payments are expensed as incurred and not included in the Company’s operating lease right-of-use ("ROU") assets and operating lease liabilities. These amounts primarily include payments for maintenance, utilities, taxes, and insurance and are excluded from the present value of the Company’s lease obligations.

The Company does not record operating lease ROU assets or operating lease liabilities for leases with an initial term of 12 months or less. The Company also combines lease and non-lease components on all new or modified operating leases into a single lease component for all classes of assets.

When a lease is terminated before the expiration of the lease term, irrespective of whether the lease is classified as a finance lease or an operating lease, the lessee would derecognize the ROU asset and corresponding lease liability. Any difference would be recognized as a gain or loss related to the termination of the lease. Similarly, if a lessee is required to make any payments or receives any consideration when terminating the lease, it would include such amounts in the determination of the gain or loss upon termination. 8

11. INCOME TAXES

The Company calculates its interim income tax provision in accordance with ASC Topic 270, Interim Reporting (“ASC 270”), and ASC 740. The Company’s effective tax rate (“ETR”) from continuing operations was (45.3)% and (16.8)% for the three and six months ended June 30, 2024, respectively, and (2.2)% and (7.5)% for the three and six months ended June 30, 2023, respectively. Income tax expense recorded by the Company during the three and six months ended June 30, 2024 was $2.6 million and $3.1 million, respectively. Income tax expense recorded by the Company during the three and six months ended June 30, 2023 was $0.2 million and $1.5 million, respectively. The difference between the ETR and federal statutory rate of 21.0% is primarily attributable to items recorded for U.S. GAAP but permanently disallowed for U.S. federal income tax purposes, recognition of a U.S. federal and state valuation allowance and state and foreign income tax provisions.

A valuation allowance is recorded when it is more-likely-than-not some of the Company’s deferred tax assets may not be realized. Significant judgment is applied when assessing the need for a valuation allowance and the Company considers future taxable income, reversals of existing deferred tax assets and liabilities and ongoing prudent and feasible tax planning strategies, in making such assessment. As of June 30, 2024, the Company’s U.S. federal, state and various foreign net deferred tax assets are not more-likely-than-not to be realized and a full valuation allowance is maintained.

The Company records uncertain tax positions in accordance with ASC 740, on the basis of a two-step process in which (i) the Company determines whether it is more likely than not a tax position will be sustained on the basis of the technical merits of such position and (ii) for those tax positions meeting the more-likely-than-not recognition threshold, the Company would recognize the largest amount of tax benefit that is more than 50.0% likely to be realized upon ultimate settlement with the related tax authority. The Company has determined it has no uncertain tax 13

positions as of June 30, 2024. The Company classifies interest and penalties recognized on uncertain tax positions as a component of income tax expense.

12. DEBT

Debt consisted of the following:

June 30, 2024 December 31, 2023
Term loan facility $ 200,314 $ 154,219
Revolving line of credit 3,651 —
Aircraft loan 9,819 10,344

Long-term debt, less current portion $ 188,749 $ 148,988

Deferred Financing Costs—Costs relating to debt issuance have been deferred and are presented as discounted against the underlying debt instrument. These costs are amortized to interest expense over the terms of the underlying debt instruments.

2021 Credit Facility—On April 27, 2021, the Company entered into a Senior Secured Credit Agreement providing for a $300.0 million credit facility comprised of a $175.0 million term loan and a $125.0 million revolving line of credit (the “2021 Credit Facility”), and used a portion of the proceeds from the 2021 Credit Facility to repay all amounts outstanding under the prior credit facility. The revolving line of credit portion of the 2021 Credit Facility includes a $20.0 million sublimit for the issuance of letters of credit. Subject to certain exceptions, all amounts under the 2021 Credit Facility will become due on April 27, 2026. The Company has the option to borrow incremental term loans or request an increase in the aggregate commitments under the revolving credit facility up to an aggregate amount of $150.0 million subject to the satisfaction of certain conditions.

In January 2024, the Company partially exercised its option to request an increase in the aggregate commitments to provide an additional $100.0 million credit availability under the 2021 Credit Facility, comprised of an additional $50.0 million term loan ("Additional Term Loan") and an additional $50.0 million in availability under the revolving line of credit.

The 2021 Credit Facility term loan must be repaid in quarterly installments and shall amortize at the following future quarterly rates:

Quarterly Installment Rate
Date 2021 Credit Facility Term Loan Additional Term Loan
June 30, 2024 1.88% 1.25%
September 30, 2024 1.88% 1.25%

March 31, 2026 2.50% 1.88%
April 27, 2026 Remaining balance Remaining balance

Quarterly installment repayments for the three and six months ended June 30, 2024 were $0.6 million and $3.9 million, respectively. Repayment in the amount of $3.3 million for the second quarter was accrued as of June 30, 2024. Exclusive of the repayment made related to quarter ended March 31, 2023, quarterly installment repayments for the three and six months ended June 30, 2023 were $2.2 million and $4.4 million, respectively.

On May 31, 2023, the Company amended its 2021 Credit Facility agreement to transition the reference rate from LIBOR to SOFR. The transition to SOFR did not materially impact the interest rate paid by the Company or change any material terms of the 2021 Credit Facility. 14

The 2021 Credit Facility term loan and the revolving line of credit bear interest subject to the applicable spread based on Company’s leverage ratio and SOFR plus 0.10% as follows:

Pricing Tier Consolidated<br>Leverage Ratio Senior Credit Facilities <br>SOFR Spread Senior Credit Facilities <br>Base Rate Spread Commitment<br>Fee Letter of Credit Fee
1 ≥ 3.75x to 1.0 2.50 % 1.50 % 0.25 % 2.50 %

5 <1.75x to 1.0 1.50 0.50 0.15 1.50

On May 30, 2023, the Company amended the interest rate swap transaction it entered into on January 27, 2022 (the "2022 Interest Rate Swap"), to convert the floating component of the interest rate on $100.0 million of borrowings to 1-Month Term SOFR and a new coupon of 1.319% until January 27, 2025. Prior to the amendment, the floating component of the interest rate was subject to LIBOR and a coupon of 1.39%. The transition to SOFR did not materially impact the interest rate paid by the Company or change any material terms of the 2022 Interest Rate Swap.

On May 30, 2023, the Company entered into a second interest rate swap transaction, fixing the floating component of the interest rate on an additional $70.0 million of borrowings to 1-Month Term SOFR and a coupon of 3.88% until April 27, 2026.

On June 5, 2024, the Company transitioned the 2022 Interest Rate Swap agreement of $100.0 million to a three-year term on $80.0 million of borrowings, with a fixed SOFR rate of 3.27%.

The 2021 Credit Facility includes a number of covenants imposing certain restrictions on the Company’s business, including, among other things, restrictions on the Company’s ability, subject to certain exceptions and baskets, to incur indebtedness, incur liens on its assets, agree to any additional negative pledges, pay dividends or repurchase stock, limit the ability of its subsidiaries to pay dividends or distribute assets, make investments, enter into any transaction of merger or consolidation, liquidate, wind-up or dissolve, or convey any part of its business, assets or property, or acquire the business, property or assets of another person, enter into sale and leaseback transactions, enter into certain transactions with affiliates, engage in any material line of business substantially different from those engaged on the closing date, modify the terms of indebtedness subordinated to the loans incurred under the 2021 Credit Facility and modify the terms of its organizational documents. The 2021 Credit Facility also includes financial covenants which required the Company to remain below a maximum total net leverage ratio of 4.25 times until the fiscal quarter ended September 31, 2022, which stepped down to 4.00 times during the fiscal quarter ending December 31, 2022 and applies through and including the fiscal quarter ending September 30, 2023 and then further steps down to 3.75 times beginning with the fiscal quarter ending December 31, 2023, and a minimum fixed charge coverage ratio of 1.25 times. In January, 2024, the Company exercised its credit facility covenant holiday, increasing its leverage capacity from 3.75 times to 4.25 times for four quarters beginning with the first quarter of 2024.

As of June 30, 2024 and December 31, 2023, the Company’s consolidated total leverage ratio (as defined in the 2021 Credit Facility) was 2.4 times and 1.9 times, respectively, and the Company was in compliance with all covenants under the 2021 Credit Facility.

The 2021 Credit Facility requires customary mandatory prepayments of the term loan and revolver and cash collateralization of letters of credit, subject to customary exceptions, including 100.0% of the proceeds of debt not permitted by the 2021 Credit Facility, 100.0% of the proceeds of certain dispositions, subject to customary reinvestment rights, where applicable, and 100.0% of insurance or condemnation proceeds, subject to customary reinvestment rights, where applicable. The 2021 Credit Facility also includes customary events of default and related acceleration and termination rights.

The weighted average interest rate on the 2021 Credit Facility for the six months ended June 30, 2024 and June 30, 2023, before giving effect to the impact of the interest rate swaps, was 7.4% and 6.3%, respectively, and after giving effect to the impact of the interest rate swaps, was 3.4%, and 2.1%, respectively.

The Company’s obligations under the 2021 Credit Facility are guaranteed by certain of the Company’s existing and future direct and indirect subsidiaries, and such obligations are secured by substantially all of the Company’s assets, including the capital stock or other equity interests in those subsidiaries.

Loan and Aircraft Security Agreement—On May 18, 2023, the Company entered into a Loan and Aircraft Security Agreement to finance $10.9 million of the purchase a new aircraft (the "Aircraft Loan"). The Aircraft Loan must be repaid in 60 monthly consecutive installments and all outstanding amounts will become due on May 18, 2028. The Aircraft Loan bears interest subject to 1-Month Term SOFR and a coupon of 1.86%. The entire principal balance may be prepaid in full subject to a 3.0%, 2.0% and 1.0% prepayment fee if paid prior to the first, second and third anniversary of the loan, respectively. The aircraft serves as collateral security for the Aircraft Loan. 15

Equipment Line of Credit—In May 2024, the Company entered into a $15.0 million equipment leasing facility for the purchase of equipment and related freight, installation costs and taxes paid. Any unused capacity on this equipment leasing facility will expire on April 15, 2025. Interest on leases financed under this facility is based on the SOFR swap rate on or closest to the closing date. Equipment leased through this line of credit met the finance lease criteria as per ASC 842 and accordingly is accounted for as finance lease right-of-use assets and finance lease liabilities.

The following is a schedule of the aggregate annual maturities of long-term debt presented on the unaudited condensed consolidated statement of financial position, gross of deferred debt issuance cost of $1.4 million, based on the terms of the 2021 Credit Facility and the Aircraft Loan:

14. COMMITMENTS AND CONTINGENCIES

Leases—The Company leases office facilities over various terms expiring through 2031. Certain of these operating leases contain rent escalation clauses. The Company also has office equipment leases that expire through 2029 (Note 6 and 12).

Other Commitments—The Company has commitments under the 2021 Credit Facility, its Aircraft Loan, its equipment line of credit and its lease obligations (Note 6 and 12).

Contingencies—The Company is subject to purchase price contingencies related to earn-outs associated with certain acquisitions (Note 7 and 13).

Legal—In the normal course of business, the Company is at times subject to pending and threatened legal actions. In management’s opinion, the potential loss resulting from the resolution of these matters is not expected to have a material effect on the unaudited condensed consolidated results of operations, financial position or cash flows of the Company.

15. CONVERTIBLE AND REDEEMABLE SERIES A-2 PREFERRED STOCK

On April 13, 2020, the Company entered into an agreement to issue 17,500 shares of the Convertible and Redeemable Series A-2 Preferred Stock with a par value of $0.0001 per share and a detachable warrant to purchase shares of the Company’s common stock with a 10-year life, in exchange for gross proceeds of $175.0 million, net of $1.3 million debt issuance costs. The Convertible and Redeemable Series A-2 Preferred Stock warrants were exercised in full on July 30, 2020. The Company paid dividends on shares of the Convertible and Redeemable Series A-2 Preferred Stock of $2.8 million and $4.1 million during the three months ended June 30, 2024 and June 30, 2023, and $5.6 million and $8.2 million during the six months ended June 30, 2024 and June 30, 2023, respectively.

The Convertible and Redeemable Series A-2 Preferred Stock terms include the following: (i) no mandatory redemption, (ii) no stated value cash repayment obligation other than in the event of certain defined liquidation events, (iii) only redeemable at the Company’s option, (iv) convertible into common stock beginning in April 2024 at a 15.0% discount to the common stock market price (with a limit of $60.0 million in stated value of Convertible and Redeemable Series A-2 Preferred Stock eligible to be converted in any 60-day period prior to the seventh anniversary of issuance and the amount of stated value of the Convertible and Redeemable Series A-2 Preferred Stock eligible for conversion limited to $60.0 million during year 5 and $120.0 million (which includes the aggregate amount of the stated value of the Convertible and Redeemable Series A-2 Preferred Stock and any accrued but unpaid dividends added to such stated value of any shares of Convertible and Redeemable Series A-2 Preferred Stock converted in year 5) during year 6), (v) 9.0% dividend rate per year with required quarterly cash payments, (vi) in an event of noncompliance, the dividend rate shall increase to 12.0% per annum for the first 90-day period from and including the date the 17

noncompliance event occurred, and thereafter shall increase to 14.0% per annum, (vii) debt incurrence test ratio of

4.5

times, and (viii) minimum repayment amount of $25.0 million. The Company may, at its option on any one or more dates, redeem all or a minimum portion (the lesser of (i) $25.0 million in aggregate stated value of the Convertible and Redeemable Series A-2 Preferred Stock and (ii) all of the Convertible and Redeemable Series A-2 Preferred Stock then outstanding) of the outstanding Convertible and Redeemable Series A-2 Preferred Stock in cash. In January 2024, the Company redeemed $60 million of the outstanding Convertible and Redeemable Series A-2 Preferred Stock with cash. As of June 30, 2024, the aggregate amount of the Convertible and Redeemable Series A-2 Preferred Stock issued and outstanding was $122.2 million, or 11,667 shares.

The Convertible and Redeemable Series A-2 Preferred Stock does not meet the definition of a liability pursuant to “ASC 480- Distinguishing Liabilities from Equity.” However, as (i) the instrument is redeemable upon a change of control as defined in the certificate of designations governing the terms of the Convertible and Redeemable Series A-2 Preferred Stock, and (ii) the Company cannot assert it would have sufficient authorized and unissued shares of common stock to settle all future conversion requests due to the variable conversion terms, the instrument is redeemable upon the occurrence of events that are not solely within the control of the Company, and therefore the Company classifies the Convertible and Redeemable Series A-2 Preferred Stock as mezzanine equity. Subsequent adjustment of the carrying value of the instrument is required if the instrument is probable of becoming redeemable. As of June 30, 2024, the Company has determined that a change of control is not probable. Additionally, as of June 30, 2024, the Company has determined that it is not probable that there will be a future conversion request that the Company is unable to settle with authorized and issued shares based on the Company’s current stock price and available shares as well as the Company’s monitoring efforts to ensure there are a sufficient number of shares available to settle any conversion request. Therefore, as of June 30, 2024, the Company has determined that the instrument is not probable of becoming redeemable, and does not believe subsequent adjustment of the carrying value of the instrument will be necessary.

The Convertible and Redeemable Series A-2 Preferred Stock contains a conversion option of the preferred shares to shares of common stock beginning on the fourth-year anniversary of the issuance date. As of June 30, 2024 and December 31, 2023, this conversion embedded feature had a net fair value of $19.6 million and $19.0 million, respectively. The change in net fair value of $0.5 million and $0.6 million for the three and six months ended June 30, 2024, respectively, and $0.5 million and $1.4 million for the three and six months ended June 30, 2023, respectively, was recorded to other expense.

16. STOCKHOLDERS’ EQUITY

On April 22, 2024, the Company issued an aggregate of 3,450,000 shares of common stock in an underwritten public offering, inclusive of the shares of common stock issued in connection with the underwriters exercise in full of their option to purchase additional shares of common stock. The Company sold the shares to the underwriters at the public offering price of $37.15 per share, less underwriting discounts and commissions of $1.67175 per share, resulting in net proceeds to the Company after deducting underwriting discounts and commissions and estimated offering expenses payable by the Company of $121.8 million.

17. NET LOSS PER SHARE

Basic net loss per share is computed by dividing net loss attributable to common stockholders by the weighted average number of common shares outstanding during each period. The Convertible and Redeemable Series A-2 Preferred Stock is considered a participating security during the applicable period. Net losses are not allocated to the Convertible and Redeemable Series A-2 stockholders, as they were not contractually obligated to share in the Company’s losses.

Diluted net loss per share is computed by dividing net loss attributable to common stockholders by the weighted average number of common and dilutive common equivalent shares outstanding for the period using the treasury-stock method or the as-converted method. Potentially dilutive shares are comprised of awards of restricted stock ("RSAs"), restricted stock units ("RSUs"), stock appreciation rights ("SARs") and shares of common stock underlying stock options outstanding under the Company's stock incentive plans. During the three and six months ended June 30, 2024 and June 30, 2023, there is no difference in the number of shares used to calculate basic and diluted shares outstanding during the applicable period due to the Company’s net loss attributable to common stockholders and potentially dilutive shares being anti-dilutive. 18

The following table summarizes the computation of basic and diluted net loss per share attributable to common stockholders of the Company:

Three Months Ended June 30, Six Months Ended June 30,
2024 2023 2024 2023
Net loss $ (10,170 ) $ (7,174 ) $ (23,527 ) $ (21,893 )
Convertible and redeemable series A-2 preferred stock dividend (2,750 ) (4,100 ) (5,564 ) (8,200 )
Net loss attributable to common stockholders – basic and diluted (12,920 ) (11,274 ) (29,091 ) (30,093 )
Weighted-average number of shares of common stock outstanding – basic and diluted 33,318 30,047 31,850 29,952
Net loss per share attributable to common stockholders – basic and diluted $ (0.39 ) $ (0.38 ) $ (0.91 ) $ (1.00 )

The following common stock equivalents were excluded from the calculation of diluted net loss per share attributable to common stockholders because their effect would have been anti-dilutive:

June 30,
2024(1) 2023(1)
Stock options 3,179,129 3,436,263
Restricted stock 2,579,982 2,325,322

18. STOCK-BASED PLANS AND COMPENSATION

Employee Equity Incentive Plans

The Company has two plans under which stock-based awards have been issued: (i) the Montrose Amended & Restated 2017 Stock Incentive Plan (“2017 Plan”) and (ii) the Montrose Amended & Restated 2013 Stock Option Plan (“2013 Plan”) (collectively the “Plans”).

The following number of shares were authorized to be issued and available for grant:

(1) In January 2024 and January 2023 the Board of Directors ratified the addition of 1,207,563 and 1,189,801 shares of common stock, respectively, to the number of shares available for issuance under the 2017 Plan pursuant to the annual increase provision of such plan. Unless the Board of Directors determines otherwise, additional annual increases will be effective on each January 1, through January 1, 2027. The 2017 Plan permits the company to settle awards, if and when vested, in cash at its discretion. Pursuant to the terms of the 2017 Plan, the number of shares authorized for issuance thereunder will only be reduced with respect to shares of common stock actually issued upon exercise or settlement of an award. Shares of common stock subject to awards that have been canceled, expired, forfeited or otherwise not issued under an award and shares of common stock subject to awards settled in cash do not count as shares of common stock issued under the 2017 Plan. Shares available for grant exclude awards of stock appreciation rights approved in December 2021 that are subject to vesting based on the achievement of certain market conditions, which have not yet been, and may not be, achieved. See footnote 1 to the table in Common Stock Reserved for Future Issuance below for additional information on stock appreciation rights. 19

Stock Appreciation Rights

As of June 30, 2024, there were 3,000,000 units of SARs outstanding under the 2017 Plan. These SARs represent the right to receive, upon exercise, a payment equal to the excess of (a) the fair market value of one share of the Company’s common stock, over (b) an exercise price of $66.79, payable, at the Company’s election, in cash or shares of common stock. These SARs vest on the 5th anniversary of the date of grant based on achievement of performance hurdles over a five year period, subject to continued service on the vesting date. The performance hurdles are as follows:

SARs Stock Price Performance Hurdle Portion of SARs Subject to Performance Hurdle
$133.58 1/3
$166.98 1/3
$200.37 1/3

20

The performance hurdles shall be deemed achieved if the average trading price per share of the Company’s common stock equals or exceeds the applicable stock price performance hurdle set forth above for the trading days falling in a consecutive 20-day period prior to the vesting date. None of the market conditions have been achieved as of June 30, 2024.

The SARs expire 10 years after the grant date. The fair value of these SARs at the grant date was $46.0 million. The weighted average remaining contract life of these SARs as of June 30, 2024 was

7.46

years.

Common Stock Reserved for Future Issuances—The Company has reserved certain stock of its authorized but unissued common stock for possible future issuance in connection with the following:

Montrose 2017 Stock Incentive Plan(1) 9,657,329 8,699,655
10,436,619 9,511,911

(1) In January 2024 and 2023, the Board of Directors ratified the addition of 1,207,563 and 1,189,801 shares of common stock, respectively, to the number of shares available for issuance under the 2017 Plan pursuant to the annual increase provision of such plan. Unless the Board of Directors determines otherwise, additional annual increases will be effective on each January 1, through January 1, 2027. The 2017 Plan permits the company to settle awards, if and when vested, in cash at its discretion. Pursuant to the terms of the 2017 Plan, the number of shares authorized for issuance thereunder will only be reduced with respect to shares of common stock actually issued upon exercise or settlement of an award. Shares of common stock subject to awards that have been canceled, expired, forfeited or otherwise not issued under an award and shares of common stock subject to awards settled in cash do not count as shares of common stock issued under the 2017 Plan. The Company expects to have sufficient shares available under the 2017 Plan to satisfy the future settlement of outstanding awards. Shares reserved for future issuance include 3,000,000 shares underlying the 3,000,000 performance SARs granted in December 2021 that are subject to vesting based on the achievement of certain market conditions. Assuming achievement at the highest price performance hurdle, approximately 2,000,000 shares of common stock would be issued upon vesting of these performance SARs. To date, none of the market conditions have been achieved.

19. SEGMENT INFORMATION

The Company has three operating and reportable segments: Assessment, Permitting and Response, Measurement and Analysis and Remediation and Reuse. These segments are monitored separately by management for performance against budget and prior year and are consistent with internal financial reporting. The Company’s operating segments are organized based upon primary services provided, the nature of the production process, types of customers, methods used to distribute the products and the nature of the regulatory environment.

Our Chief Executive Officer, who serves as the Chief Operating Decision Maker ("CODM"), reviews Segment Adjusted EBITDA as the primary measure of operating performance for all three operating segments. Segment Adjusted EBITDA is the calculated Company’s Earnings before Interest, Tax, Depreciation and Amortization (“EBITDA”), adjusted to exclude certain transactions such as stock-based compensation, acquisition costs and fair value changes in financial instruments, amongst others. Beginning in the first quarter of 2023, the calculation of Segment adjusted EBITDA no longer adjusts for start-up losses and investment in new services as the CODM no longer reviews the Segment Adjusted EBITDA measure without these costs. The CODM does not review segment assets as a measure of segment performance.

During the first quarter of 2023, the Company determined to discontinue one of its non-core specialty service lines within the lab testing business (the "Discontinued Specialty Lab"). On December 29, 2023, the Company sold the assets of the Discontinued Specialty Lab for a total sales price of $4.8 million, of which $0.5 million was received in cash and $4.3 million was issued as a promissory note receivable. The promissory note receivable is subject to an annual 9.0% interest rate and will be repaid in 60 monthly installments with the remaining balance payable in full on December 29, 2028. The promissory note receivable balance, net of expected loss and payment, was $2.1 million as of June 30, 2024 and December 31, 2023, respectively. The discontinuation of this specialty service line, which was part of the Company's Measurement and Analysis segment, did not represent a strategic shift that had a major effect on the Company’s operations and financial results, therefore it did not meet the requirements to be classified as discontinued operations.

Corporate and Other includes costs associated with general corporate overhead (including executive, legal, finance, safety, human resources, marketing and IT related costs) that are not directly related to supporting operations. Overhead costs that are directly related to supporting operations (such as insurance, software, licenses, shared services and payroll processing costs) are allocated to the operating segments on a basis that reasonably approximates an estimate of the use of these services. 22

This discussion contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from such forward-looking statements. Factors that could cause or contribute to those differences include, but are not limited to, those identified below and those discussed in the section entitled “Forward-Looking Statements”, and elsewhere in this filing and our other filings with the SEC, including in Item 1A. Risk Factors in the 2023 Form 10-K.

Overview

Since our inception in 2012, our mission has been to help clients and communities meet their environmental goals and needs. According to data derived from a 2023 Environmental Industry Study prepared by Environmental Business International, Inc., or EBI, which we commissioned, the global environmental industry is estimated to be approximately $1.44 trillion, with $494.0 billion concentrated in the United States.

Our Segments

We provide environmental services to our clients through three business segments—Assessment, Permitting and Response, Measurement and Analysis and Remediation and Reuse. For more information on each of our operating segments, see Item 1. “Business” in the 2023 Form 10-K.

Assessment, Permitting and Response

Assessment, Permitting and Response segment provides scientific advisory and consulting services to support environmental assessments, environmental emergency response and recovery, toxicology consulting and environmental audits and permits for current operations, facility upgrades, new projects, decommissioning projects and development projects. We work closely with clients to navigate the regulatory process at the local, state, provincial and federal levels, identify the potential environmental and political impacts of their decisions and develop practical mitigation approaches, as needed. In addition to environmental toxicology, and given our expertise in helping businesses plan for and respond to disruptions, our scientists and response teams have helped clients navigate their preparation for and response to emergency response situations.

Measurement and Analysis

Measurement and Analysis segment is one of the largest providers of environmental testing and laboratory services in North America. Our highly credentialed teams test and analyze air, water and soil to determine concentrations of contaminants, as well as the toxicological impact of contaminants on flora, fauna and human health. Our offerings include source and ambient air testing and monitoring, leak detection, and advanced multi-media laboratory services, including air, soil, stormwater, wastewater and drinking water analysis.

Remediation and Reuse

Remediation and Reuse segment provides clients with engineering, design, and implementation services, primarily to treat contaminated water, remove contaminants from soil or create biogas from waste. Our employees, including engineers, scientists and consultants, provide these services to assist our clients in designing solutions, managing products and mitigating environmental risks and liabilities at their locations. We do not own the properties or facilities at which we implement these projects or the underlying liabilities, nor do we own material amounts of the equipment used in projects.

These operating segments have been structured and organized to align with how we view and manage the business with the full lifecycle of our clients’ targeted environmental concerns and needs in mind. Within each segment, we cover similar service offerings, regulatory frameworks, internal operating structures and client types. Corporate activities not directly related to segment performance, including general corporate expenses, interest and taxes, are reported separately.

Key Factors that Affect Our Business and Our Results

Our operating results and financial performance are influenced by a variety of internal and external trends and other factors. Some of the more important factors are discussed briefly below.

Acquisitions

We have been, and expect to continue to be, an acquisitive company. Acquisitions have expanded our environmental service capabilities across all three segments, our access to technology, as well as our geographic reach in the United States, Canada, Europe and Australia. The table below sets forth the number of acquisitions completed, revenues generated by and the percentage of total revenues attributable to those acquisitions completed during the three and six months ended June 30, 2024 and June 30, 2023:

Three Months Ended June 30, Six Months Ended June 30,
(Revenues in thousands) 2024 2023 2024 2023
Acquisitions completed 2 2 4 4
Revenues attributable to acquisitions completed in the period(1) $ 7,700 $ 10,617 $ 11,600 $ 11,585
Percentage of revenues 4.4 % 6.7 % 3.5 % 4.0 %

_________________________________

  • Acquisitions revenue amounts in Note 7 to our unaudited condensed consolidated financial statements included in Part I, Item 1. “Financial Statements” includes second quarter revenue from acquisitions completed in the first quarter of 2024 and 2023 of $6.4 million and $1.7 million, respectively, whereas this disclosure only considers revenue attributable to the acquisitions acquired during the three and six months ended June 30, 2023 and 2024.

Revenues from acquired companies exclude intercompany revenues from revenue synergies realized between business lines within operating segments, as these are eliminated at the consolidated segment and Company level. We expect our revenue growth to continue to be driven in significant part by acquisitions. See Note 7 to our unaudited condensed consolidated financial statements included in Part I, Item 1. “Financial Statements.”

As a result of our acquisitions, goodwill and other intangible assets represent a significant proportion of our total assets, and amortization of intangible assets has historically been a significant expense. Our historical financial statements also include other acquisition-related costs, including costs relating to external legal support, diligence and valuation services and other transaction and integration-related matters. In addition, in any year gains and losses from changes in the fair value of business acquisition contingencies such as earn-outs could be significant. The amount of each for the three and six months ended June 30, 2024 and June 30, 2023, was:

Three Months Ended June 30, Six Months Ended June 30,
(in thousands) 2024 2023 2024 2023
Amortization expense $ 7,137 $ 7,350 $ 14,566 $ 14,590
Acquisition-related costs 1,082 2,696 3,607 3,471
Fair value changes in business acquisition contingencies (136 ) 353 (242 ) (45 )

We expect that amortization of identifiable intangible assets and other acquisition-related costs, assuming we continue to acquire, will continue to be significant.

Additionally, we made an earn-out payment of $1.5 million in March 2024 in connection with our acquisition of Huco Consulting, Inc. ("Huco"), of which, $0.4 million was paid in cash, and the remaining $1.1 million in the Company's common stock. In connection with certain of our acquisitions, we may make up to $40.4 million in aggregate earn-out payments between the years 2024 and 2026, of which up to $14.2 million may be paid only in cash, up to $13.1 million may be paid only in common stock and up to $13.1 million may be paid, at our option, in cash or common stock. See Note 7 to our unaudited condensed consolidated financial statements included in Part I, Item 1. “Financial Statements.”

Organic Growth

We define organic growth as the change in revenues excluding revenues from (i) our environmental emergency response business, (ii) acquisitions for the first twelve months following the date of acquisition, and (iii) businesses held for sale, disposed of or discontinued. Management uses organic growth as one of the means by which it assesses our results of operations. Organic growth is not, however, a measure of revenue growth calculated in accordance with U.S. generally accepted accounting principles, or GAAP, and should be considered in conjunction with revenue growth calculated in accordance with GAAP. We have grown organically over the long term and expect to continue to do so.

Discontinued Service Lines and Contracts

Periodically, or when circumstances warrant, we evaluate the performance of our business services to ensure that performance and outlook are consistent with expectations, and that the services offered are consistent with the Company’s mission.

As part of this evaluation, during the first quarter of 2023, we determined to sell one of our specialty lab testing businesses, the Discontinued Specialty Lab, whose service offering was non-core to the Company’s business. On December 29, 2023, we sold the assets of the Discontinued Specialty Lab for a total sales price of $4.8 million. The discontinuation of this specialty service line did not represent a strategic shift that had a major effect on our operations and financial results, therefore it did not meet the requirements to be classified as discontinued operations.

Revenue Mix

Our segments and our business lines within each segment generate different levels of profitability and, accordingly, shifts in the mix of revenues between segments can impact our consolidated reported net income, net loss margin, Segment Adjusted EBITDA and Segment Adjusted EBITDA margin from quarter to quarter and year to year. Inter-company revenues between business lines within segments have been eliminated. See Note 19 to our unaudited condensed consolidated financial statements included in Part 1, Item 1 “Financial Statements.”

Financing Costs

Total debt at June 30, 2024 was $212.4 million net of deferred debt issuance costs, which was an increase of $49.2 million compared to December 31, 2023. The increase is primarily driven by the additional $50.0 million in capacity under our revolving credit facility and an additional $3.6 million issued under the revolving line of credit offset by repayments and amortization of the various debt noted.

Interest expense, net was $4.0 million and $7.3 million in the three and six months ended June 30, 2024, respectively, and $1.9 million and $3.4 million in the three and six months ended June 30, 2023, respectively. We expect interest expense to remain a significant cost as we continue to leverage our credit facility to support our operations and future acquisitions.

See Note 12 to our unaudited condensed consolidated financial statements included in Part 1, Item 1 “Financial Statements” and “Liquidity and Capital Resources.”

Corporate and Operational Infrastructure Investments

Our historical operating results reflect the impact of our ongoing investments in our corporate infrastructure to support our growth. We have made and expect to continue to make investments in our business platform that we believe have laid the foundation for continued growth. Investments in logistics, quality, risk management, sales and marketing, safety, human resources, research and development, finance and information technology and other areas enable us to support continued growth. These investments should allow us to improve our margins over time.

Seasonality

Due to the field-based nature of certain of our services, weather patterns generally impact our field-based teams’ ability to operate in the winter months. As a result, our operating results could experience some quarterly variability with generally lower revenues and lower earnings in the first and fourth quarters and higher overall revenues and earnings in the second and third quarters. As we continue to grow and expand into new geographies and service lines, quarterly variability in our Measurement and Analysis and Remediation and Reuse segments may deviate from historical trends.

Earnings Volatility

In addition to the impact of seasonality on earnings, our emergency response business exposes us to potentially significant revenue and earnings fluctuations tied both to the timing of large environmental emergency response projects following an incident or natural disaster or more broad scale events such as the COVID-19 pandemic. We also saw significant emergency response revenue in 2023 from a single event. Demand for environmental emergency response services remains difficult to predict and as a result, we may have experienced revenues and earnings in prior years that are not indicative of future results, making those periods particularly difficult comparisons for future periods. Earnings volatility is also driven by the timing of large projects, particularly in our Remediation and Reuse segment, and the impact of acquisitions. As a result of these factors, and because demand for environmental services is not driven by specific or predictable patterns in one or more fiscal quarters, our business is better assessed based on yearly results.

Revenues

Three Months Ended June 30, Change Six Months Ended June 30, Change
(in thousands, except %) 2024 2023 % 2024 2023 %
Revenues $ 173,325 $ 159,101 8.9 % $ 328,650 $ 290,529 13.1 %

All values are in US Dollars.

Revenue for the three months ended June 30, 2024 increased $14.2 million or 8.9% as compared to the three months ended June 30, 2023. The increase was primarily driven by acquisitions completed in and subsequent to the quarter ended June 30, 2023, which contributed revenues of $23.6 million, and strong organic growth of $7.7 million driven primarily by the Measurement and Analysis and Assessment, Permitting and Response segments. These increases were partially offset by $14.7 million lower environmental emergency response service revenues, the shift away from lower margin revenue in our biogas business, and prior year revenues from the Discontinued Specialty Lab of $2.4 million, which was sold in December 2023. Environmental emergency response revenues were $12.9 million in the three months ended June 30, 2024, compared to $27.6 million in the three months ended June 30, 2023.

Revenue for the six months ended June 30, 2024 increased $38.1 million or 13.1% as compared to the six months ended June 30, 2023. The increase was primarily driven by acquisitions completed in and subsequent to the quarter ended June 30, 2023, which contributed revenues of $48.2 million, and $16.2 million of strong organic growth in both our Measurement and Analysis and Assessment, Permitting and Response segments. These increases were partially offset by $22.2 million lower environmental emergency response service revenues, lower water treatment revenues and the shift away from lower margin revenue in our biogas business, and prior year revenues from the Discontinued Specialty Lab of $3.9 million. Revenue from environmental response was $28.6 million in the six months ended June 30, 2024 compared to $50.8 million in the six months ended June 30, 2023.

See “—Segment Results of Operations” below for revenue by segment analysis.

Cost of Revenues

Three Months Ended June 30, Change Six Months Ended June 30, Change
(in thousands, except %) 2024 2023 % 2024 2023 %
Cost of revenues (exclusive of depreciation and amortization) $ 104,086 $ 98,196 6.0 % $ 200,643 $ 179,829 11.6 %

All values are in US Dollars.

Cost of revenues consists of all direct costs required to provide services, including fixed and variable direct labor costs, equipment purchases and rental, and other outside services, field and lab supplies, vehicle costs and travel-related expenses. Variable costs of revenues generally follow the same trends as revenue, while fixed costs tend to change primarily as a result of acquisitions.

Cost of revenues for the three months ended June 30, 2024 compared to the three months ended June 30, 2023 increased by $5.9 million driven primarily by an $8.5 million increase in direct labor costs and a $3.9 million increase in other cost of revenues, partially offset by a $6.9 million decrease in field supplies and equipment costs. Cost of revenues as a percentage of revenue for the three months ended June 30, 2024 was 60.1%, compared to 61.7% for the three months ended June 30, 2023. This decrease was driven primarily by lower equipment costs, as a result of lower water treatment and biogas revenues.

Cost of revenues for the six months ended June 30, 2024 compared to the six months ended June 30, 2023 increased by $20.8 million driven primarily by a $19.5 million increase in direct labor costs, a $5.2 million increase in outside services costs, and a $2.7 million increase in other cost of revenues, partially offset by a $8.3 million decrease in field supplies and equipment costs. Cost of revenues as a percentage of revenue for the six months ended June 30, 2024 was 61.0%, compared to 61.9% for the six months ended June 30, 2023. This decrease was driven primarily by revenue mix.

Selling, General and Administrative Expense

Three Months Ended June 30, Change Six Months Ended June 30, Change
(in thousands, except %) 2024 2023 % 2024 2023 %
Selling, general and administrative expense $ 59,239 $ 55,247 7.2 % $ 116,313 $ 104,860 10.9 %

All values are in US Dollars.

Selling, general and administrative expense consists of general corporate overhead, including executive, legal, finance, safety, risk management, human resource, marketing and information technology related costs, as well as indirect operational costs of labor, rent, insurance and stock-based compensation.

Selling, general and administrative expense for the three months ended June 30, 2024 compared to the three months ended June 30, 2023 increased $4.0 million or 7.2% primarily due to an increase of approximately $5.9 million in selling, general and administrative expense from companies acquired in and subsequent to the three months ended June 30, 2023. The increase was partially offset by a $1.6 million decrease in acquisition-related costs and a decrease of $1.1 million related to a decrease in bad debt expense.

Selling, general and administrative expense for the six months ended June 30, 2024 compared to the six months ended June 30, 2023 increased $11.5 million or 10.9% primarily due to an increase of $11.6 million in selling, general and administrative expense from companies acquired in and subsequent to the six months ended June 30, 2023. The increase was partially offset by a decrease of $2.4 million related to a decrease in bad debt expense and lower stock-based compensation of $1.5 million.

See Part I, Item 3. “Quantitative and Qualitative Disclosures About Market Risk” for additional information regarding the impact of inflation on our business.

Depreciation and Amortization

Depreciation and amortization $ 12,515 $ 11,398 9.8 % $ 24,168 $ 21,953 10.1 %

All values are in US Dollars.

The increase in depreciation of property and equipment and the amortization of intangible assets and finance leases were primarily driven by an increase of $1.5 million and $2.2 million in depreciation of property and equipment during the three and six months ended June 30, 2024 compared to the prior year periods, respectively, as a result of higher property and equipment outstanding during the applicable period. See Notes 5 and 6 to our unaudited condensed consolidated financial statements included in Part 1, Item 1. “Financial Statements.”

All values are in US Dollars.

Interest expense, net for the three and six months ended June 30, 2024 and 2023 increased primarily as a result of higher interest rates and higher debt balance.

Weighted average interest rates as of June 30, 2024 and June 30, 2023 were 7.4% and 6.3%, respectively. See “—Key Factors that Affect Our Business and Our Results—Financing Costs” and Notes 12 and 13 to our unaudited condensed consolidated financial statements included in Part I, Item 1. “Financial Statements.”

All values are in US Dollars.

The income tax expense for the three and six months ended June 30, 2024 increased compared to the three and six months ended June 30, 2023 primarily as a result of the change in treatment of Canadian tax credits associated with the acquisition of Matrix in June 2023 in addition to an increase in deductible goodwill amortization associated with recent U.S. acquisitions. The income tax expense is primarily related to operations in the United States, Canada and Australia.

Total Operating Segments $ 173,325 $ 159,101 8.9 % $ 328,650 $ 290,529 13.1 %

All values are in US Dollars.

Assessment, Permitting and Response segment revenues for the three and six months ended June 30, 2024 decreased compared to the three and six months ended June 30, 2023 due to a decline in revenues from environmental emergency responses of $14.7 million and $22.2 million, respectively, partially offset by strong organic growth within our non-response consulting and advisory services.

Measurement and Analysis segment revenues for the three and six months ended June 30, 2024 increased compared to the three and six months ended June 30, 2023 as a result of strong organic growth, partially offset by the sale of the Discontinued Specialty Lab in December 2023, which contributed $1.5 million and $2.2 million, respectively, to the prior year periods.

Remediation and Reuse segment revenues for the three and six months ended June 30, 2024 increased compared to the three and six months ended June 30, 2023, primarily driven by acquisitions completed in and subsequent to the second quarter of 2023, which contributed revenues of $23.6 million and $46.8 million in the three and six months ended June 30, 2024, respectively, partially offset by expected lower water treatment and renewable services revenues.

All values are in US Dollars.

Assessment, Permitting and Response Segment Adjusted EBITDA for the three and six months ended June 30, 2024 decreased compared to the three and six months ended June 30, 2023 primarily due to lower emergency response revenues, partially offset by higher Segment Adjusted EBITDA margin as a result of strong organic growth in our non-response advisory services and favorable revenue mix.

Measurement and Analysis Segment Adjusted EBITDA, for the three and six months ended June 30, 2024 increased compared the three and six months ended June 30, 2023 as a result of higher revenues driven by organic growth and higher Segment Adjusted EBITDA margin driven by benefits of improved operating leverage.

Remediation and Reuse Segment Adjusted EBITDA for the three and six months ended June 30, 2024 increased compared the three and six months ended June 30, 2023 due to higher revenues. Segment Adjusted EBITDA in the three months ended June 30, 2024 also benefited from higher Segment Adjusted EBITDA margin, driven by acquisitions and improved Matrix margins. Adjusted EBITDA growth in the six months ended June 30, 2023 was partially offset by lower year-to-date Segment Adjusted EBITDA margin primarily attributable to the acquisition of Matrix in June 2023, which was break-even in the first quarter of 2024 and lower revenues from certain renewable and water projects compared to the 2023 period.

Corporate and other costs for the three and six months ended June 30, 2024 when compared the three and six months ended June 30, 2023 increased primarily due to higher investments in IT support and information security. Corporate costs as a percentage of revenues were flat year-over-year in both the three and six months ended June 30, 2024.

Liquidity and Capital Resources

Liquidity describes the ability of a company to generate sufficient cash flows to meet the cash requirements of its business operations, including working capital needs, debt service, acquisitions, other commitments and contractual obligations. We consider liquidity in terms of cash flows from operations and other sources, including availability under our credit facility, and their sufficiency to fund our operating and investing activities.

Our principal sources of liquidity have been borrowings under our credit facilities, other borrowing arrangements, proceeds from the issuance of common and preferred stock and cash generated by operating activities. Historically, we have financed our operations and acquisitions from a combination of cash generated from operations, periodic borrowings under senior secured credit facilities, and proceeds from the issuance of common and preferred stock. Our primary cash needs are for day to day operations, to fund working capital requirements, to fund our acquisition strategy and any related cash earn-out obligations, to pay interest and principal on our indebtedness and dividends on our Series A-2 preferred stock, and to make capital expenditures. Additionally, in connection with certain acquisitions, we agree to earn-out provisions and other purchase price adjustments that may require future payments. We may make up to $40.4 million in aggregate earn-out payments between the years 2024 and 2026 in connection with the acquisitions of Sensible, Vandrensning, EPIC, and 2DOT, of which up to $14.2 million may be paid only in cash, up to $13.1 million may be paid only in common stock and up to $13.1 million may be paid in cash or, at our option, in common stock. See Note 7 to our unaudited condensed consolidated financial statements included in Part 1, Item 1. “Financial Statements.”

We expect to continue to fund our liquidity requirements, including any cash earn-out payments that may be required in connection with acquisitions, through cash generated from operations and borrowings under our credit facility. We believe these sources will be sufficient to fund our cash needs for the short- and long-term.

Cash Flows

The following table summarizes our cash flows for the periods presented:

Six Months Ended June 30,
(in thousands) 2024 2023
Net cash provided by (used in):
Operating activities $ (21,127 ) $ 24,512
Investing activities (87,937 ) (86,983 )
Financing activities 102,829 (3,959 )
Change in cash, cash equivalents and restricted cash $ (6,235 ) $ (66,430 )

Operating Activities

Cash flows from operating activities can fluctuate from period-to-period as earnings, working capital needs and the timing of payments for contingent consideration, taxes, bonus payments and other operating items impact reported cash flows.

For the six months ended June 30, 2024, net cash used in operating activities was $21.1 million compared to net cash provided by operating activities of $24.5 million for the six months ended June 30, 2023. The period-over-period decrease of $45.6 million was primarily due to an increase in accounts receivable and contract assets of $38.0 million, as a result of temporary invoicing delays following the integration of Matrix as well as several large projects with new customers with elongated payment cycles, and a decrease in accrued payroll and benefits of $7.9 million following larger bonus payments made in March 2024 than in the prior year.

Investing Activities

For the six months ended June 30, 2024, net cash used in investing activities was $87.9 million, driven by cash paid for the acquisitions of EPIC, 2DOT, ETA, and Paragon, net of cash acquired of $70.3 million, as well as $17.9 million in purchases of property and equipment, and $1.7 million in proprietary software development costs.

For the six months ended June 30, 2023, net cash used in investing activities was $87.0 million, driven by cash paid for the acquisitions of Matrix, GreenPath, Frontier and EAI, net of cash acquired of $63.1 million, as well as $21.0 million in cash consideration for purchases of property and equipment (which included the purchase of a $12.2 million replacement aircraft for use in emergency responses following a crash in February 2023), and $2.0 million in proprietary software development costs.

Financing Activities

For the six months ended June 30, 2024, net cash provided by financing activities was $102.8 million. Cash provided by financing activities was driven by net proceeds from the issuance of common stock through a public offering of $121.8 million, proceeds from the issuance of an additional term loan of $50.0 million and proceeds from the exercise of stock options of $1.4 million, partially offset by a partial redemption of the Series A-2 preferred stock of $60.0 million, dividends on the Series A-2 preferred stock of $5.6 million, and aggregate repayments made on our term loan, finance leases and aircraft loan of $7.5 million.

For the six months ended June 30, 2023, net cash used in financing activities was $4.0 million. Cash used in financing activities was driven by the quarterly dividends on the Series A-2 preferred stock of $8.2 million, the term loan amortization payments of $6.6 million related to our 2021 Credit Facility, the repayment of finance leases of $2.2 million, and the payment of acquisition-related contingent consideration of $1.2 million, partially offset by proceeds received from the aircraft loan of $10.9 million and the exercise of stock options of $3.3 million.

Credit Facilities

See Note 12 to our unaudited condensed consolidated financial statements included in Part I, Item 1. “Financial Statements.”

Series A-2 Preferred Stock

See Note 15 to our unaudited condensed consolidated financial statements included in Part I, Item 1. “Financial Statements.”

Critical Accounting Policies and Estimates

Our 2023 Form 10-K includes a summary of the critical accounting policies and estimates we believe are the most important to aid in understanding our financial results. There have been no material changes to those critical accounting policies and estimates as disclosed therein, other than as described in Note 2 to our unaudited condensed consolidated financial statements included in Part I, Item 1. “Financial Statements.”

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

Interest Rate Risk

We have market risk exposure arising from changes in interest rates on our credit facility, which bears interest at rates that are benchmarked subject to the Company’s leverage ratio and SOFR. Based on our overall interest rate exposure to variable rate debt outstanding as of June 30, 2024, which factors in our interest rate swaps on $150.0 million of debt, a 1.0% increase or decrease in interest rates on the term loan, aircraft loan, and revolver would impact our annual income (loss) before income taxes by approximately $0.6 million.

Inflation Risk

We experienced higher labor and significantly higher travel and other direct costs in the fiscal year ended December 31, 2022 and December 31, 2023 as a result of inflation, particularly in our Measurement and Analysis and Remediation and Reuse segments. In the six months ended June 30, 2024, we also experienced, and continue to experience, higher labor costs as a result of inflation. We believe we have successfully raised prices in businesses with short term contracts to offset these inflationary effects. We also have and are continuing to raise prices on medium term (one to four quarter) contracts as these contracts are renewed or new contracts are won, and as a result have been able to offset much of the impact of inflation to date. We expect to continue to raise prices if direct costs continue to increase, and although inflation has increased our Selling, general and administrative expense in the six months ended June 30, 2024, we do not believe over a longer period of time that inflation will have a material effect on our business, financial condition or results of operations. If our costs were to become subject to additional and unanticipated significant sustained inflationary pressures, we may not be able to fully offset such higher costs through price increases. Our inability or failure to do so could adversely affect our business, financial condition and results of operations.

Foreign Exchange Risk

Foreign exchange risk exposure arises because we sell our services throughout the United States, Canada, Australia and Europe. Our exposure to this risk has increased significantly due to our acquisitions of Paragon and Matrix in Canada, EPIC in Australia, and to a lesser extent, Vandrensning in Europe. Revenues in certain foreign countries as well as certain expenses related to those revenues are transacted in currencies other than the U.S. dollar. As such, our future operating results are exposed to changes in exchange rates. When the U.S. dollar weakens against foreign currencies, the dollar value of revenues denominated in foreign currencies increases. When the U.S. dollar strengthens, the opposite situation occurs. Additionally, previously invoiced amounts can be positively or negatively affected by changes in exchange rates in the course of collection. A 1.0% increase or decrease in the U.S. dollar exchange rate would impact revenues by approximately $1.5 million and would have a negligible impact on annual net (loss) income.

Item 4. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

As required by Rule 13a-15(b) under the Exchange Act, our management, including our Chief Executive Officer and Chief Financial Officer, carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act), as of June 30, 2024, the end of the period covered by this Quarterly Report on Form 10-Q. Based on the foregoing, our Chief Executive Officer and Chief Financial Officer concluded that, as of June 30, 2024, the end of the period covered by this Quarterly Report on Form 10-Q, our disclosure controls and procedures were effective at the reasonable assurance level.

Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) that occurred during the quarter ended June 30, 2024, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Limitations on Effectiveness of Controls

Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures or our system of internal control over financial reporting will prevent or detect all errors and all fraud. A control system, no matter how well designed or operated, can provide only reasonable, but not absolute, assurance that the objectives of the system of internal control are met. The design of our control system reflects the fact that there are resource constraints, and that the benefits of such control system must be considered relative to their costs. Further, because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control failures and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the intentional acts of individuals, by collusion of two or more people, or by management override of the controls. The design of any system of controls is also based in part on certain assumptions about the likelihood of future events, and there can be no assurance that the design of any particular control will always succeed in achieving its objective under all potential future conditions.

Item 1. Legal Proceedings.

From time to time, we are subject to various legal proceedings that arise in the normal course of our business activities, including those involving labor and employment, anti-discrimination, commercial disputes and other matters. We are not a party to any litigation the outcome of which, if determined adversely to us, would individually or in the aggregate be reasonably expected to have a material adverse effect on our results of operations or financial position. Regardless of outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors.

Item 1A. Risk Factors.

There have been no material changes to our risk factors from the risk factors disclosed in our 2023 Form 10-K. The risks described in our 2023 Form 10-K, in addition to the other information set forth in this Quarterly Report on Form 10-Q, are not the only risks facing we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

On May 31, 2024, we issued an aggregate of 61,707 shares of common stock to the former owners of Paragon as purchase price consideration. The issuance of common stock was exempt from the registration requirements of the Securities Act pursuant to Section 4(a)(2) thereof as a transaction by an issuer not involving any public offering.

On July 1, 2024, we issued an aggregate of 30,953 shares of common stock to the former owner of Spirit as purchase price consideration. The issuance of common stock was exempt from the registration requirements of the Securities Act pursuant to Section 4(a)(2) thereof as a transaction by an issuer not involving any public offering.

Item 3. Defaults Upon Senior Securities.

None.

Item 4. Mine Safety Disclosures.

Not applicable.

Item 5. Other Information.

On May 14, 2024, Allan Dicks, Chief Financial Officer, adopted a trading plan intended to satisfy Rule 10b5-1(c) to (a) sell up to 2,000 shares of Company common stock between November 11, 2024 and November 13, 2025, subject to certain conditions, (b) sell up to 16,310 shares of Company common stock between August 14, 2024 and November 13, 2025, subject to certain conditions, and (c) purchase up to 98,260 shares of Company common stock in connection with the exercise of stock options, and sell up to 98,260 of such shares between August 14, 2024 and November 13, 2025, subject to certain conditions.

On June 14, 2024, James K. Price, Director, adopted a trading plan intended to satisfy Rule 10b5-1(c) to sell 280,000 shares of Company Common Stock between September 12, 2024 and June 13, 2025, subject to certain conditions.
