BASIS OF PRESENTATION Basis of Presentation The accompanying consolidated financial statements are of ICF International, Inc. (“ICFI”) and its principal subsidiary, ICF Consulting Group, Inc. (“Consulting,” and together with ICFI, the “Company”), and have been prepared in accordance with United States (“U.S.”) generally accepted accounting principles (“U.S. GAAP”). Consulting is a wholly owned subsidiary of ICFI. ICFI is a holding company with no operations or assets other than its investment in the common stock of Consulting. All other subsidiaries of the Company are wholly owned by Consulting. Intercompany transactions and balances have been eliminated. The terms “federal” or “federal government” refer to the U.S. federal government, and “state and local” or “state and local government” refer to U.S. state (including territories) and local governments, unless otherwise indicated. Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities, and the reported amounts of revenue and expenses. Key estimates include estimates related to variable consideration on contracts with customers, costs to complete fixed-price contracts, bonus and other incentive compensation, reserves for tax benefits and valuation allowances on deferred tax assets, collectability of receivables, valuation and useful lives of acquired tangible and intangible assets, impairment of goodwill and long-lived assets, and contingencies. Actual results experienced by the Company may differ from management’s estimates. Interim Results The unaudited consolidated financial statements included in this Quarterly Report on Form 10-Q have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). These rules and regulations permit some of the information and footnote disclosures normally included in annual financial statements, prepared in accordance with U.S. GAAP, to be condensed or omitted. In management’s opinion, the unaudited consolidated financial statements contain all adjustments that are of a normal recurring nature, necessary for a fair presentation of the results of operations and financial position of the Company for the interim periods presented. The Company reports operating results and financial data in one operating segment and reporting unit. Operating results for the three-month and the nine-month periods ended September 30, 2024 and 2023 are not necessarily indicative of the results that may be expected for the full year. These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements for the fiscal year ended December 31, 2023 and the notes thereto included in the Company’s Annual Report on Form 10-K. Recent Accounting Pronouncements Recent Accounting Pronouncements Not Yet Adopted Segment Reporting In November 2023, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2023-07: Improvements to Reportable Segment Disclosures to update reportable segment disclosure requirements for public entities under the Accounting Standards Codification (“ASC”). ASU 2023-07 enhances the current segment reporting disclosures of Topic 280 by requiring disclosure of significant segment expenses that are regularly reviewed by the Chief Operating Decision Maker (the “CODM”), the amount and description of other segment items, and interim disclosures of each reportable segment’s profit or loss and assets. ASU 2023-07 also requires public entities that have a single reportable segment to provide all of the disclosures required in Topic 280, as amended. ASU 2023-07 is effective for the Company for the fiscal year ending December 31, 2024 and interim periods within the 2025 fiscal year on a retrospective basis, with early adoption permitted. The Company expects to adopt the amendments of ASU 2023-07 for the fiscal year ending December 31, 2024, but does not expect the adoption to have a material impact, if any, on the consolidated financial statements. 8 Income Taxes In December 2023, the FASB issued ASU 2023-09, Income Taxes: Improvements to Income Tax Disclosures, which requires greater disaggregation of income tax rates and amounts paid by entities. ASU 2023-09 specifically requires all entities to disclose, on an annual basis, disaggregated domestic and foreign pre-tax income or loss from continuing operations and the disaggregated income tax expense or benefit by federal, state, and foreign components, and a tabular rate reconciliation, using both percentages and reporting currency amounts, of eight specific categories as well as any individual reconciling items that are equal to or greater than 5% of a threshold computed by multiplying pretax income or loss from continuing operations by the applicable federal rate. Additionally, the amendments also require disclosure of income taxes paid disaggregated by federal, state, and foreign jurisdictions as well as any individual jurisdictions over 5% of the total income taxes paid. ASU 2023-09 is effective for the Company for the fiscal year ending December 31, 2025, with early adoption permitted. The amendments may be adopted on a prospective or retrospective basis. The Company is currently evaluating the impact of the adoption of ASU 2023-09 but does not expect the adoption to have a material impact, if any, on the consolidated financial statements. NOTE 2 – RESTRICTED CASH The following table provides a reconciliation of cash and cash equivalents and restricted cash reported within the consolidated balance sheets for the periods presented to the total of cash, cash equivalents, and restricted cash shown in the consolidated statements of cash flows for the nine months ended September 30, 2024 and 2023: September 30, 2024 September 30, 2023 Beginning Ending Beginning Ending Cash and cash equivalents $ 6,361 $ 6,911 $ 11,257 $ 5,084 Restricted cash 3,088 724 1,711 2,770 Total of cash, cash equivalents, and restricted cash shown in the consolidated statements of cash flows $ 9,449 $ 7,635 $ 12,968 $ 7,854 NOTE 3 – CONTRACT RECEIVABLES, NET Contract receivables, net consisted of the following: September 30, 2024 December 31, 2023 Billed and billable $ 220,690 $ 210,919 Allowance for expected credit losses ( 8,278 ) ( 5,435 ) Contract receivables, net $ 212,412 $ 205,484 The Company sells certain billed contract receivables in accordance with its Master Receivables Purchase Agreement (the “MRPA”) with MUFG Bank, Ltd. (“MUFG”). The contract receivables that are sold without recourse and where the Company does not retain any ongoing financial interest in the transferred receivables, other than providing servicing activities, are accounted for as sales under ASC 860, Transfers and Servicing (“ASC 860”). Consequently, these contract receivables are derecognized from the Company’s consolidated balance sheets at the date of the sale, and the cash received from MUFG is presented as part of cash flows from operating activities. 9 The following is a reconciliation of billed contract receivables sold to MUFG that were eligible and accounted for as sales under ASC 860, including billed contract receivables sold to MUFG and collected from customers on behalf of MUFG during the nine months ended September 30, 2024 and 2023, and the balance of billed contract receivables not yet collected from customers as of September 30, 2024 and 2023, respectively: As of and for the Nine Months Ended September 30, 2024 September 30, 2023 Beginning balance, billed contract receivables sold and not yet collected (1) $ 21,302 $ 3,819 Billed contract receivables sold during the period (2) 482,469 159,480 Collections from customers during the period (2) ( 473,037 ) ( 131,580 ) Ending balance, billed contract receivables sold and not yet collected (3) $ 30,735 $ 31,719 (1) The beginning balances represent billed contract receivables that were previously sold and derecognized by the Company but have not yet been collected from customers as of January 1, 2024 and 2023 , respectively. (2) For the nine months ended September 30, 2024 and 2023, the Company recorded net inflows of $ 9.4 million and $ 27.9 million , respectively, in its cash flows from operating activities from the sale of billed contract receivables. (3) The ending balances represent billed contract receivables that were sold and derecognized by the Company but have not yet been collected from customers as of September 30, 2024 and 2023 , respectively. The following is a reconciliation of cash collections from customers of billed contract receivables previously sold to MUFG that were eligible and accounted for as sales under ASC 860, including collections from customers on behalf of MUFG of previously sold billed contract receivables and remittances of cash collections to MUFG during the nine months ended September 30, 2024 and 2023, and the balance of cash collected but not yet remitted to MUFG as of September 30, 2024 and 2023, respectively: As of and for the Nine Months Ended September 30, 2024 September 30, 2023 Beginning balance, cash collected but not yet remitted to MUFG (1) $ 21,796 $ 6,164 Collections from customers during the period (2) 473,037 131,580 Remittances to MUFG during the period (2) ( 463,558 ) ( 127,303 ) Ending balance, cash collected but not yet remitted to MUFG (3) $ 31,275 $ 10,441 (1) The beginning balances represent cash collected from customers on behalf of MUFG for billed contract receivables that were previously sold and derecognized by the Company but have not yet been remitted to MUFG as of January 1, 2024 and 2023 , respectively. (2) For the nine months ended September 30, 2024 and 2023, the Company recorded net inflows of $ 9.5 million and $ 4.3 million , respectively, in its cash flows from operating activities from the collection of billed contract receivables that were sold but not yet remitted to MUFG. (3) The ending balances are included as part of “Accrued expenses and other current liabilities” on the Company’s consolidated balance sheets. The Company services the receivables sold by collecting cash and remitting it to MUFG. The related servicing fee received from MUFG was immaterial. The aggregate impact of the sale of billed contract receivables on the Company’s operating cash flows was $ 18.9 million and $ 32.2 million for the nine months ended September 30, 2024 and 2023, respectively. The Company also sold certain billed contract receivables to MUFG that did not qualify as sales under ASC 860. Consequently, the cash received from and remitted back to MUFG is presented as cash from financing activities within “Proceeds from other short-term borrowings” and “Repayments of other short-term borrowings” on the Company’s consolidated statements of cash flows. At September 30, 2024 and December 31, 2023, the amounts due to MUFG for cash collected and not yet remitted for billed contract receivables sold that did not qualify as sales under ASC 860 totaled $ 2.7 million and $ 6.9 million , respectively. These amounts are included as part of “Accrued expenses and other current liabilities” on the Company’s consolidated balance sheets. 10 NOTE 4 – LEASES At September 30, 2024 , the Company had operating and finance leases for facilities and equipment with remaining terms ranging from 1 to 14 years .

The average interest rate on borrowings under the Credit Facility was 6.8 % for the nine months ended September 30, 2024 and 6.7 % for the twelve months ended December 31, 2023, respectively. Inclusive of the impact of floating-to-fixed interest rate swaps (see “Note 7 – Derivative Instruments and Hedging Activities”), the average interest rate was 5.4 % for the nine months ended September 30, 2024 and 5.6 % for the twelve months ended December 31, 2023, respectively. Future contractual repayments of debt principal are as follows: Payments due by Term Loan Delayed-Draw Term Loan Revolving Credit Total September 30, 2025 $ — $ 13,750 $ — $ 13,750 September 30, 2026 — 16,500 — 16,500 May 6, 2027 (Maturity) 200,250 181,500 10,000 391,750 Total $ 200,250 $ 211,750 $ 10,000 $ 422,000 11 NOTE 6 – REVENUE RECOGNITION Disaggregation of Revenue The Company disaggregates revenue from clients into categories that depict how the nature, amount, and uncertainty of revenue and cash flows are affected by economic and business factors.

Contract liabilities result from advance payments received on a contract or from billings in excess of revenue recognized. The following table summarizes the contract assets and liabilities as of September 30, 2024 and December 31, 2023: September 30, 2024 December 31, 2023 Contract assets $ 237,742 $ 201,832 Contract liabilities ( 17,176 ) ( 21,997 ) Net contract assets (liabilities) $ 220,566 $ 179,835 The increase in net contract assets (liabilities) is primarily due to the timing difference between the performance of services and billings to customers. During the nine months ended September 30, 2024 and 2023, the Company recognized $ 17.1 million and $ 17.3 million in revenue related to the contract liabilities balance at December 31, 2023 and 2022, respectively. 12 Unfulfilled Performance Obligations The Company had $ 1.4 billion in unfulfilled performance obligations (“UPO”) as of September 30, 2024. The Company expects to recognize the remaining UPO as revenue of approximately 8 % by December 31, 2024 , 65 % by December 31, 2025 , and the remainder thereafter. NOTE 7 – DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES At September 30, 2024 , the Company had floating-to-fixed interest rate swap agreements for an aggregate notional amount of $ 275.0 million, of which $ 100.0 million will mature on February 28, 2025 , $ 75.0 million will mature on February 28, 2028 , and $ 100.0 million will mature on June 27, 2028 . The Company has designated the swap agreements as cash flow hedges. See “Note 5 – Debt” for details on the impact of the swap agreements on the Company’s interest rates. See “Note 12 – Fair Value” for the fair value of these swaps. NOTE 8 – INCOME TAXES A r econciliation of the Company’s statutory rate to the effective tax rate for the three and nine months ended September 30, 2024 and 2023 is as follows: Three Months Ended September 30, Nine Months Ended September 30, 2024 2023 2024 2023 Statutory tax rate 21.0 % 21.0 % 21.0 % 21.0 % State taxes, net of federal benefit 6.0 % 5.8 % 6.0 % 5.8 % Executive compensation 1.6 % 1.4 % 1.6 % 1.4 % Corporate-owned life insurance ( 0.5 %) ( 0.2 %) ( 0.5 %) ( 0.2 %) Other permanent differences 0.4 % 0.4 % 0.4 % 0.3 % Prior year tax adjustments ( 11.0 %) ( 27.1 %) ( 3.7 %) ( 10.8 %) Worthless stock — ( 20.2 %) — ( 7.3 %) Capital loss — — — ( 6.7 %) Valuation allowance 0.9 % 3.1 % 1.0 % 1.9 % Equity-based compensation ( 0.3 %) ( 0.6 %) ( 1.7 %) ( 1.6 %) Uncertain tax position 4.2 % 19.1 % 4.4 % 6.9 % Tax credits ( 8.5 %) ( 1.3 %) ( 8.5 %) ( 1.3 %) Effective tax rate 13.8 % 1.4 % 20.0 % 9.4 % The prior year tax adjustments, uncertain tax position and tax credits recognized during the three and nine months ended September 30, 2024 and 2023 are both primarily related to the Research & Experimentation (“R&E”) credits. The Company’s effective income tax rate was higher for the three months and nine months ended September 30, 2024 as compared to the three months and nine months ended September 30, 2023 primarily due to restructuring of the ownership of the Company’s Canadian entities and the deduction for worthless stock related to the wind-down of the Company’s commercial marketing business in the United Kingdom (the “U.K.”) during the second and the third quarters of 2023, respectively, which reduced the Company’s 2023 effective tax rate. 13 NOTE 9 – STOCKHOLDERS’ EQUITY Accumulated Other Comprehensive Loss Accumulated other comprehensive loss as of September 30, 2024 and 2023 included the following: Three Months Ended September 30, 2024 Foreign Currency Translation Adjustments Change in Fair Value of Interest Rate Hedge Agreements Total Accumulated other comprehensive (loss) income at June 30, 2024 $ ( 14,463 ) $ 2,919 $ ( 11,544 ) Current period other comprehensive (loss) income: Other comprehensive (loss) income before reclassifications 4,745 ( 5,099 ) ( 354 ) Amounts reclassified from accumulated other comprehensive (loss) income (1) — ( 1,670 ) ( 1,670 ) Effect of taxes ( 758 ) 1,831 1,073 Total current period other comprehensive (loss) income 3,987 ( 4,938 ) ( 951 ) Accumulated other comprehensive (loss) income at September 30, 2024 $ ( 10,476 ) $ ( 2,019 ) $ ( 12,495 ) Three Months Ended September 30, 2023 Foreign Currency Translation Adjustments Change in Fair Value of Interest Rate Hedge Agreement and Other Adjustments Total Accumulated other comprehensive (loss) income at June 30, 2023 $ ( 10,833 ) $ 4,517 $ ( 6,316 ) Current period other comprehensive (loss) income: Other comprehensive (loss) income before reclassifications ( 3,487 ) 4,379 892 Amounts reclassified from accumulated other comprehensive (loss) income — ( 2,101 ) ( 2,101 ) Effect of taxes ( 2,227 ) ( 617 ) ( 2,844 ) Total current period other comprehensive (loss) income ( 5,714 ) 1,661 ( 4,053 ) Accumulated other comprehensive (loss) income at September 30, 2023 $ ( 16,547 ) $ 6,178 $ ( 10,369 ) Nine Months Ended September 30, 2024 Foreign Currency Translation Adjustments Change in Fair Value of Interest Rate Hedge Agreements Total Accumulated other comprehensive (loss) income at December 31, 2023 $ ( 12,695 ) $ 810 $ ( 11,885 ) Current period other comprehensive (loss) income: Other comprehensive (loss) income before reclassifications 2,877 1,161 4,038 Amounts reclassified from accumulated other comprehensive (loss) income (1) — ( 5,002 ) ( 5,002 ) Effect of taxes ( 658 ) 1,012 354 Total current period other comprehensive (loss) income 2,219 ( 2,829 ) ( 610 ) Accumulated other comprehensive (loss) income at September 30, 2024 $ ( 10,476 ) $ ( 2,019 ) $ ( 12,495 ) 14 Nine Months Ended September 30, 2023 Foreign Currency Translation Adjustments Change in Fair Value of Interest Rate Hedge Agreement and Other Adjustments Total Accumulated other comprehensive (loss) income at December 31, 2022 $ ( 14,056 ) $ 5,923 $ ( 8,133 ) Current period other comprehensive (loss) income: Other comprehensive (loss) income before reclassifications ( 82 ) 5,658 5,576 Amounts reclassified from accumulated other comprehensive (loss) income — ( 5,299 ) ( 5,299 ) Effect of taxes ( 2,409 ) ( 104 ) ( 2,513 ) Total current period other comprehensive (loss) income ( 2,491 ) 255 ( 2,236 ) Accumulated other comprehensive (loss) income at September 30, 2023 $ ( 16,547 ) $ 6,178 $ ( 10,369 ) (1) The Company expects to reclassify $ 1.1 million of gains related to the Change in Fair Value of Interest Rate Hedge Agreements from accumulated other comprehensive (loss) income into earnings during the next 12 months. Share Repurchases The Company repurchased shares under the $ 200.0 million share repurchase program authorized by the Company’s board of directors. In addition, the Company repurchased shares in connection with the vesting of restricted stock units (“RSUs”) and performance share awards (“PSAs”) granted to employees. Repurchases for the three and nine months ended September 30, 2024 and 2023 are as follows: Three Months Ended September 30, 2024 2023 Shares Amount Paid Shares Amount Paid Share Repurchase Program — $ — — $ — Vesting of RSUs 2,383 377 91 12 Total 2,383 $ 377 91 $ 12 Nine Months Ended September 30, 2024 2023 Shares Amount Paid Shares Amount Paid Share Repurchase Program 191,000 $ 26,519 180,000 $ 18,126 Vesting of RSUs and PSAs 48,414 7,047 45,467 4,743 Total 239,414 $ 33,566 225,467 $ 22,869 15 NOTE 10 – STOCK-BASED COMPENSATION The Company’s 2018 Amended and Restated Omnibus Incentive Plan (the “2018 A&R Omnibus Plan”) allows the Company to grant up to 2,050,000 total shares of common stock to officers, key employees, and non-employee directors. As of September 30, 2024, the Company had approximately 1,018,803 shares available for grant under the 2018 A&R Omnibus Plan. The following awards were granted during the three and nine months ended September 30, 2024 and 2023: Awards Granted Average Grant Date Fair Value Awards Granted Average Grant Date Fair Value Three Months Ended Three Months Ended Nine Months Ended Nine Months Ended September 30, September 30, September 30, September 30, 2024 2023 2024 2023 2024 2023 2024 2023 Employee Stock Awards 672 — $ 153.50 $ — 83,467 113,569 $ 152.59 $ 107.29 Cash-Settled RSUs 3,012 2,281 $ 153.50 $ 130.47 37,570 68,745 $ 152.64 $ 110.04 Non-Employee Director Stock Awards 6,618 8,211 $ 135.91 $ 127.81 6,618 8,211 $ 135.91 $ 127.81 Total 10,302 10,492 127,655 190,525 The total stock-based compensation expense was $ 6.6 million and $ 19.3 million for the three and nine months ended September 30, 2024, respectively, and $ 5.2 million and $ 15.9 million for the three and nine months ended September 30, 2023, respectively. The unrecognized compensation expense at September 30, 2024 was $ 34.0 million , which is expected to vest over the next 1.5 years. NOTE 11 – EARNINGS PER SHARE The Company’s earnings per share (“EPS”) is computed by dividing reported net income by the weighted-average number of shares outstanding. Diluted EPS (“U.S. GAAP Diluted EPS”) considers the potential dilution that could occur if the Company’s common stock options, RSUs, and PSAs were exercised or converted into the Company’s common stock. PSAs are included in the computation of diluted shares only to the extent that the underlying performance conditions: (i) are satisfied as of the end of the reporting period or (ii) would be considered satisfied if the end of the reporting period were the end of the related performance period and the result would be dilutive under the treasury stock method. As of September 30, 2024, the PSAs granted during the year ended December 31, 2022 met the related performance conditions for the initial performance period and were included in the calculation of U.S. GAAP Diluted EPS. However, the PSAs granted during the year ended December 31, 2023 and during the nine months ended September 30, 2024 have not yet completed their initial two-year performance period and therefore were excluded from the calculation of U.S. GAAP Diluted EPS. EPS, including the dilutive effect of stock awards for each period reported is summarized below: Three Months Ended Nine Months Ended September 30, September 30, (in thousands, except per share data) 2024 2023 2024 2023 Net Income $ 32,679 $ 23,740 $ 85,607 $ 60,450 Weighted-average number of basic shares outstanding during the period 18,760 18,815 18,752 18,795 Dilutive effect of stock awards 150 159 163 163 Weighted-average number of diluted shares outstanding during the period 18,910 18,974 18,915 18,958 Basic EPS $ 1.74 $ 1.26 $ 4.57 $ 3.22 Diluted EPS $ 1.73 $ 1.25 $ 4.53 $ 3.19 A total of 324 and 190 shares of restricted stock awards were excluded from the calculation of EPS for the three and nine months ended September 30, 2024 because they were anti-dilutive. There were no shares excluded for the three and nine months ended September 30, 2023 . 16 NOTE 12 – FAIR VALUE Financial instruments measured at fair value on a recurring basis and their location within the accompanying consolidated balance sheets are as follows: September 30, 2024 (in thousands) Level 1 Level 2 Level 3 Total Location on Balance Sheet Assets: Interest rate swaps - current portion $ — $ 1,674 $ — $ 1,674 Prepaid expenses and other assets Company-owned life insurance policies — 23,160 — 23,160 Other assets Liabilities: Interest rate swaps - current portion $ — $ 564 $ — $ 564 Accrued expenses and other current liabilities Interest rate swaps - long-term portion — 3,917 — 3,917 Other long-term liabilities December 31, 2023 (in thousands) Level 1 Level 2 Level 3 Total Location on Balance Sheet Assets: Interest rate swaps - current portion $ — $ 4,820 $ — $ 4,820 Prepaid expenses and other assets Interest rate swaps - long-term portion — 398 — 398 Other assets Company-owned life insurance policies — 20,438 — 20,438 Other assets Liabilities: Interest rate swaps - long-term portion $ — $ 4,184 $ — $ 4,184 Other long-term liabilities NOTE 13 – COMMITMENTS AND CONTINGENCIES Letters of Credit The Company had open standby letters of credit totaling $ 1.8 million at both September 30, 2024 and December 31, 2023, respectively. Open standby letters of credit reduce the Company’s borrowing capacity under the Credit Facility. Guarantees At September 30, 2024 and December 31, 2023 , the Company had $ 6.5 million and $ 7.9 million, respectively, of bank guarantees for facility leases and contract performance obligations. Litigation and Claims The Company is involved in various legal matters and proceedings arising in the ordinary course of business. While these matters and proceedings cause it to incur costs, including, but not limited to, attorneys’ fees, the Company currently believes that any ultimate liability arising out of these matters and proceedings will not have a material adverse effect on its financial position, results of operations, or cash flows. 17 Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations FORWARD-LOOKING STATEMENTS Some of the statements in this Quarterly Report on Form 10-Q (this “Quarterly Report”) constitute forward-looking statements as defined in the Private Securities Litigation Reform Act of 1995, as amended. These statements involve known and unknown risks, uncertainties, and other factors that may cause our actual results, levels of activity, performance, or achievements to be materially different from any future results, levels of activity, performance, or achievements expressed or implied by such forward-looking statements. In some cases, you can identify these statements by forward-looking words such as “anticipate,” “believe,” “could,” “estimate,” “expect,” “intend,” “may,” “plan,” “potential,” “should,” “will,” “would,” or similar words. You should read statements that contain these words carefully. The risk factors described in our filings with the Securities and Exchange Commission (the “SEC”), as well as any cautionary language in this Quarterly Report, provide examples of risks, uncertainties, and events that may cause actual results to differ materially from the expectations described in the forward-looking statements, including, but not limited to: • Our dependence on contracts with United States (“U.S.”) federal, state and local, and international governments, agencies, and departments for the majority of our revenue; • Changes in federal government budgeting and spending priorities; • Failure by Congress or other governmental bodies to approve budgets and debt ceiling increases in a timely fashion and related reductions in government spending; • Uncertainties relating to the outcomes of the U.S. presidential election in November 2024; • Failure of the presidential administration and Congress to agree on spending priorities, which may result in temporary shutdowns of non-essential federal functions, including our work to support such functions; • Results of routine and non-routine government audits and investigations; • Dependence of our commercial work on certain sectors of the global economy that are highly cyclical; • Failure to realize the full amount of our backlog; • Risks inherent in being engaged in significant and complex disaster relief efforts and grant management programs involving multiple tiers of government in very stressful environments; • Risks resulting from expanding our service offerings and client base; • Difficulties in identifying attractive acquisitions available at acceptable prices; • Acquisitions we undertake presenting integration challenges, failing to perform as expected, increasing our liabilities, and/or reducing our earnings; and • Additional risks as a result of having international operations. Our forward-looking statements are based on the beliefs and assumptions of our management and the information available to our management at the time these disclosures were prepared. Although we believe the expectations reflected in these statements are reasonable, we cannot guarantee future results, levels of activity, performance, or achievements. You should not place undue reliance on these forward-looking statements, which apply only as of the date of this Quarterly Report. We undertake no obligation to update these forward-looking statements, even if our situation changes in the future. The terms “we,” “our,” “us,” and “the Company,” as used throughout this Quarterly Report, refer to ICF International, Inc. and its subsidiaries, unless otherwise indicated. The terms “federal” or “federal government” refer to the U.S. federal government, and “state and local” or “state and local government” refer to U.S. state and local governments and the governments of U.S. territories. The following discussion and analysis is intended to help the reader understand our business, financial condition, results of operations, and liquidity and capital resources. You should read this discussion in conjunction with our consolidated financial statements and the related notes contained elsewhere in this Quarterly Report and our Annual Report on Form 10-K for the fiscal year ended December 31, 2023, filed with the SEC on February 28, 2024 (our “Annual Report”). 18 OVERVIEW AND OUTLOOK We provide professional services and technology-based solutions, including management, technology, and policy consulting and implementation services. We help our clients conceive, develop, implement, and improve solutions that address complex business, natural resource, social, technological, and public safety issues. Our services primarily support clients that operate in three key markets: • Energy, Environment, Infrastructure, and Disaster Recovery; • Health and Social Programs; and • Security and Other Civilian & Commercial. We provide services to our diverse client base that deliver value throughout the entire life cycle of a policy, program, project, or initiative. Our primary services include: • Advisory Services; • Program Implementation Services; • Analytics Services; • Digital Services; and • Engagement Services. We report operating results and financial data as a single segment based on the consolidated information used by our chief operating decision-maker in evaluating the financial performance of our business and allocating resources. Our single segment represents our core business: professional services to our broad array of clients. Although we describe our multiple service offerings to clients that operate in three markets to provide a better understanding of the scope and scale of our business, we do not manage our business or allocate our resources based on those service offerings or client markets. Rather, on a project-by-project basis, we assemble the best team from throughout the enterprise to deliver highly customized solutions that are tailored to meet the needs of each client. We believe that, in the long-term, demand for our services will continue to grow as government, industry, and other stakeholders seek to address critical long-term societal and natural resource issues due to heightened concerns about the environment and use of clean energy and energy efficiency; health promotion, treatment, and cost control; the means by which public health can be improved effectively on a cross-jurisdiction basis; natural disaster recovery and rebuild efforts; and ongoing homeland security threats. We also see significant opportunity to further leverage our digital and client engagement capabilities across our client base. Our future results will depend on the success of our strategy to enhance our client relationships and seek larger engagements that span the entire program life cycle, and to complete and successfully integrate additional strategic acquisitions. We will continue to focus on building scale in our vertical and horizontal domain expertise, developing business with our existing clients as well as new customers, and replicating our business model in selective geographies. In doing so, we will continue to evaluate strategic acquisition opportunities that enhance our subject matter knowledge, broaden our service offerings, and/or provide scale in specific geographies. Although we continue to see favorable long-term market opportunities, there are certain business challenges facing all government service providers. Administrative and legislative actions by the federal government to address changing priorities or in response to the budget deficit and/or debt ceiling could have a negative impact on our business, which may result in a reduction to our revenue and profit and adversely affect cash flow. Similarly, the very nature of opportunities arising out of disaster recovery means they can involve unusual challenges. Factors such as the overall stress on communities and people affected by disaster recovery situations, political complexities and challenges among involved government agencies, and a higher-than-normal risk of audits and investigations may result in a reduction to our revenue and profit and adversely affect cash flow. However, we believe we are well positioned to provide a broad range of services in support of initiatives that will continue to be priorities to the federal government, as well as to state and local and international governments and commercial clients. 19 RESULTS OF OPERATIONS Three Months Ended September 30, 2024 Compared to Three Months Ended September 30, 2023 The table below sets forth select line items of our unaudited consolidated statements of comprehensive income, the percentage of revenue for these select items, and the period-over-period rate of change and percentage of revenue for the periods indicated. Three Months Ended September 30, Dollars Percentages of Revenue Year-to-Year Change (dollars in thousands) 2024 2023 2024 2023 Dollars Percent Revenue $ 516,998 $ 501,519 100.0 % 100.0 % $ 15,479 3.1 % Direct Costs: Direct labor and related fringe benefit costs 197,473 187,421 38.2 % 37.4 % 10,052 5.4 % Subcontractor and other direct costs 127,574 136,083 24.7 % 27.1 % (8,509 ) (6.3 %) Total Direct Costs 325,047 323,504 62.9 % 64.5 % 1,543 0.5 % Operating Costs and Expenses: Indirect and selling expenses 132,816 131,553 25.7 % 26.2 % 1,263 1.0 % Depreciation and amortization 4,820 5,917 0.9 % 1.2 % (1,097 ) (18.5 %) Amortization of intangible assets 8,291 8,644 1.6 % 1.7 % (353 ) (4.1 %) Total Operating Costs and Expenses 145,927 146,114 28.2 % 29.1 % (187 ) (0.1 %) Operating Income 46,024 31,901 8.9 % 6.4 % 14,123 44.3 % Interest, net (7,195 ) (10,557 ) (1.4 %) (2.1 %) 3,362 (31.8 %) Other (expense) income (899 ) 2,736 (0.2 %) 0.5 % (3,635 ) (132.9 %) Income before Income Taxes 37,930 24,080 7.3 % 4.8 % 13,850 57.5 % Provision for Income Taxes 5,251 340 1.0 % 0.1 % 4,911 1444.4 % Net Income $ 32,679 $ 23,740 6.3 % 4.7 % $ 8,939 37.7 % Revenue. The increase in revenue was driven by $11.2 million, $2.7 million, and $2.3 million from our commercial, U.S. federal government, and U.S. state and local government clients, respectively, offset by a decrease of $0.7 million from our international government clients. Our revenue from client markets was impacted in varying amounts by our exit from the commercial marketing business during 2023. The following were changes in revenue from our various client markets: • Energy, Environment, Infrastructure, and Disaster Recovery client market revenues increased $31.3 million, or 15.3%, driven primarily by increases of $22.3 million, $8.3 million, and $0.8 million from commercial, U.S. federal government, and U.S. state and local government clients, respectively. • Health and Social Programs client market revenues decreased $13.2 million, or 6.3%, driven by a decrease in subcontractor pass-through on several of our U.S. federal contracts and our exit from the commercial marketing business during 2023, resulting in decreases of $10.6 million, $2.5 million, and $1.8 million from U.S. federal government, commercial, and international government clients, respectively, offset by an increase of $1.7 million from U.S. state and local government clients. • Security and Other Civilian & Commercial client market revenues decreased $2.6 million, or 3.0%, primarily driven by our exit from the commercial marketing business during 2023 resulting in decreases of $8.7 million and $0.2 million from commercial and U.S. state and local government clients, respectively, offset by increases of $5.0 million and $1.3 million from U.S. federal government and international government clients, respectively. Revenue for the three months ended September 30, 2024 includes subcontractor and other direct costs, which decreased $8.5 million, or 6.3%, from the third quarter of 2023 and totaled $127.6 million and $136.1 million for the three months ended September 30, 2024 and 2023, respectively, and the margin on such costs. Direct Costs . The increase of $1.5 million in direct costs was driven by an increase in direct labor and related fringe benefit costs which reflected the growth in the business, offset by a decrease in subcontractor and other direct costs as well as our exit from the commercial marketing and events business during 2023. For the three months ended September 30, 2024 and 2023, direct labor and related fringe benefit costs as a percentage of direct costs were 60.8% and 57.9%, respectively, and subcontractor and other direct costs as a percentage of direct costs were 39.2% and 42.1%, respectively. As a percentage of revenue, direct labor and related fringe benefit costs were 38.2% and 37.4%, respectively, and subcontractor and other direct costs were 24.7% and 27.1%, respectively, for the three months ended September 30, 2024 and 2023. Total direct costs as a percentage of revenue were 62.9% for the three months ended September 30, 2024, compared to 64.5% for the three months ended September 30, 2023. 20 Indirect and selling expenses. For the three months ended September 30, 2024, our indirect and selling expenses increased by $1.3 million, or 1.0%, compared to the prior year, primarily from general and administrative costs. As a result, our indirect and selling expenses as a percentage of revenue decreased to 25.7% for the three months ended September 30, 2024 from 26.2% for the three months ended September 30, 2023. Depreciation and amortization . The decrease in depreciation and amortization was primarily due to having fewer capital assets as a result of the divestiture of our U.S. commercial marketing business in the third quarter of 2023. Amortization of intangible assets. The decrease in amortization of intangible assets was primarily due to having fewer intangible assets in the third quarter of 2024 compared to 2023 as a result of the divestiture of our U.S. commercial marketing business in the third quarter of 2023. Interest, net. The decrease of $3.4 million in interest, net, was primarily from a decrease of our average debt balance to $462.9 million for the three months ended September 30, 2024, compared to $621.1 million for the same period in 2023. The decrease in our average debt balance was due, in part, to collection of receivables, decrease in our interest rates, as well as an increase in utilization of our Master Receivables Purchase Agreement (the “MRPA”) with MUFG Bank, Ltd. (“MUFG”). Use of floating-to-fixed interest rate swap agreements to hedge the variable interest portion of our debt reduced our interest expense by $1.7 million compared to $2.1 million for the same period in 2023. Inclusive of the impact of the swap agreements, our interest expense for the three months ended September 30, 2024 was $6.2 million compared to $8.8 million for the same period in 2023 and our interest rate inclusive of the swap agreements was 5.3% for the three months ended September 30, 2024 compared to 5.5% for 2023. Other (expense) income. The change in other (expense) income of $3.6 million was primarily due to a pre-tax gain of $2.4 million recognized in the third quarter of 2023 and an impact of $1.5 million as a result of changes in foreign currency exchange rates. Provision for Income Taxes . Our effective income tax rate for the three months ended September 30, 2024 and 2023 was 13.8% and 1.4%, respectively. The difference was primarily due to the deduction for worthless stock related to the wind-down of our commercial marketing business in the U.K. during the third quarter of 2023 which reduced effective income tax rate for the three months ended September 30, 2023. See “Note 8 – Income Taxes” in the “Notes to Consolidated Financial Statements” in this Quarterly Report. 21 Nine Months Ended September 30, 2024 Compared to Nine Months Ended September 30, 2023 The table below sets forth select line items of our unaudited consolidated statements of comprehensive income, the percentage of revenue for these select items, and the period-over-period rate of change and percentage of revenue for the periods indicated. Nine Months Ended September 30, Dollars Percentages of Revenue Year-to-Year Change (dollars in thousands) 2024 2023 2024 2023 Dollars Percent Revenue $ 1,523,463 $ 1,484,886 100.0 % 100.0 % $ 38,577 2.6 % Direct Costs: Direct labor and related fringe befit costs 584,017 555,745 38.3 % 37.4 % 28,272 5.1 % Subcontractor and other direct costs 380,894 405,728 25.0 % 27.3 % (24,834 ) (6.1 %) Total Direct Costs 964,911 961,473 63.3 % 64.8 % 3,438 0.4 % Operating Costs and Expenses: Indirect and selling expenses 389,001 381,808 25.5 % 25.7 % 7,193 1.9 % Depreciation and amortization 15,303 19,052 1.0 % 1.3 % (3,749 ) (19.7 %) Amortization of intangible assets 24,873 27,154 1.6 % 1.8 % (2,281 ) (8.4 %) Total Operating Costs and Expenses 429,177 428,014 28.1 % 28.8 % 1,163 0.3 % Operating Income 129,375 95,399 8.6 % 6.4 % 33,976 35.6 % Interest, net (23,136 ) (30,146 ) (1.5 %) (2.0 %) 7,010 (23.3 %) Other (expense) income 767 1,501 0.1 % 0.1 % (734 ) (48.9 %) Income before Income Taxes 107,006 66,754 7.2 % 4.5 % 40,252 60.3 % Provision for Income Taxes 21,399 6,304 1.4 % 0.4 % 15,095 239.5 % Net Income $ 85,607 $ 60,450 5.8 % 4.1 % $ 25,157 41.6 % Revenue. The increase in revenue was driven by $15.1 million, $9.6 million, $7.4 million, and $6.5 million from commercial, U.S. federal government, U.S. state and local governments, and international government clients, respectively. Our revenue from client markets was impacted in varying amounts by our exit from the commercial marketing and events businesses during 2023. The following were changes in revenue from our various client markets: • Energy, Environment, Infrastructure, and Disaster Recovery client market revenues increased $97.5 million, or 16.4%, in 2024 compared to 2023, driven primarily by $66.7 million and $26.3 million from commercial and U.S. federal government clients, respectively. • Health and Social Programs client market revenues decreased $35.8 million, or 5.8%, in 2024 compared to 2023. This was driven by a decrease in subcontractor pass-throughs on several of our U.S. federal contracts and our exit from the commercial marketing business during 2023, resulting in decreases of $32.7 million and $13.9 million from U.S. federal government and commercial clients, respectively, offset by increases of $5.8 million and $5.1 million from U.S. state and local government and international government clients, respectively. • Security and Other Civilian & Commercial client market revenues decreased $23.1 million, or 8.5%, in 2024 compared to 2023. The decrease was primarily driven by our exit from the commercial marketing and events business during 2023 resulting in decreases of $37.6 million and $1.3 million from commercial and international clients, respectively, offset by an increase of $16.0 million from U.S. federal government clients. Revenue for the nine months ended September 30, 2024 includes subcontractor and other direct costs, which decreased $24.8 million, or 6.1%, and totaled $380.9 million and $405.7 million for the nine months ended September 30, 2024 and 2023, respectively, and the margin on such costs. Direct Costs . The increase in direct costs was driven by an increase in direct labor and related fringe benefit costs which reflected the growth in the business, and offset by a decrease in subcontractor and other direct costs, primarily as a result of our exit from the commercial marketing and events business during 2023. For the nine months ended September 30, 2024 and 2023, direct labor and related fringe benefit costs as a percentage of direct costs were 60.5% and 57.8%, respectively, and subcontractor and other direct costs as a percentage of total direct costs were 39.5% and 42.2%, respectively. As a percentage of revenue, direct labor and related fringe benefit costs were 38.3% and 37.4%, respectively, and subcontractor and other direct costs were 25.0% and 27.3% respectively, for the nine months ended September 30, 2024 and 2023. Total direct costs as a percentage of revenue were 63.3% for the nine months ended September 30, 2024, compared to 64.8% for the nine months ended September 30, 2023. 22 Indirect and selling expenses. Indirect and selling expenses as a percentage of revenue were consistent at 25.5% for the nine months ended September 30, 2024 compared to 25.7% for 2023. Depreciation and amortization . The decrease in our depreciation and amortization was primarily due to having fewer capital assets primarily as a result of the divestiture of our U.S. commercial marketing business in the third quarter of 2023. Amortization of intangible assets. The decrease in amortization of intangible assets was primarily due to having fewer intangible assets primarily as a result of the divestiture of our U.S. commercial marketing business in the third quarter of 2023. Interest, net. The decrease in interest, net, was primarily from a decrease of our average debt balance to $488.4 million for the nine months ended September 30, 2024 compared to $641.4 million for the same period in 2023. The decrease in our average debt balance was due, in part, to collection of receivables, decrease in our interest rates, as well as an increase in the utilization of the MRPA. Use of floating-to-fixed interest rate swap agreements to hedge the variable interest portion of our debt reduced our interest expense by $5.0 million for the nine months ended September 30, 2024 compared to $5.2 million for the same period in 2023. Inclusive of the impact of the swap agreements, our interest expense for the nine months ended September 30, 2024 was $20.1 million compared to $26.9 million for 2023 and our interest rate inclusive of the swap agreements was 5.4% and 5.5% for the nine months ended September 30, 2024 and 2023, respectively. Other income. The change in other income was primarily due to the impact of changes in foreign currency exchange rates. Provision for Income Taxes . Our effective income tax rate for the nine months ended September 30, 2024 and 2023 was 20.0% and 9.4%, respectively. The difference was primarily due to the impact of a tax planning strategy regarding the ownership structure of our Canadian subsidiaries implemented during 2023 as well as the deduction for worthless stock related to the wind-down of our commercial marketing business in the U.K. during the third quarter of 2023 which reduced the effective income tax rate for the nine months ended September 30, 2023. See “Note 8 – Income Taxes” in the “Notes to Consolidated Financial Statements” in this Quarterly Report. NON-GAAP MEASURES The following tables provide reconciliations of financial measures that are not calculated in accordance with generally accepted accounting principles in the U.S. to their most comparable U.S. GAAP measures (“non-GAAP”). While we believe that these non-GAAP financial measures provide additional information to investors and may be useful in evaluating our financial information and assessing ongoing trends to better understand our operations, they should be considered supplemental in nature and not as a substitute for financial information prepared in accordance with U.S. GAAP. Other companies may define similarly titled non-GAAP measures differently, thus limiting their use for comparability. EBITDA and Adjusted EBITDA Earnings before interest, tax, and depreciation and amortization (“EBITDA”) is a measure we use to evaluate operating performance. Adjusted EBITDA is EBITDA further adjusted to eliminate the impact of certain items that we do not consider to be indicative of the performance of our ongoing operations (“Adjusted EBITDA”). We evaluate these adjustments on an individual basis based on both the quantitative and qualitative aspects of the item, including their size and nature, as well as whether we expect them to recur as part of our normal business on a regular basis. EBITDA and Adjusted EBITDA are not intended to be measures of free cash flow as these measures do not include certain cash requirements such as interest payments, tax payments, capital expenditures, and debt service. 23 The following table presents a reconciliation of net income to EBITDA and Adjusted EBITDA for the periods indicated. Three Months Ended Nine Months Ended September 30, September 30, (in thousands) 2024 2023 2024 2023 Net income $ 32,679 $ 23,740 $ 85,607 $ 60,450 Interest, net 7,195 10,557 23,136 30,146 Provision for income taxes 5,251 340 21,399 6,304 Depreciation and amortization 13,111 14,561 40,176 46,206 EBITDA 58,236 49,198 170,318 143,106 Impairment of long-lived assets (1) — 2,912 — 3,806 Acquisition and divestiture-related expenses (2) 139 1,779 205 4,685 Severance and other costs related to staff realignment (3) 449 595 1,184 4,455 Charges for facility consolidations and office closures (4) — 2,220 — 2,579 Pre-tax gain from divestiture of a business (5) (298 ) (2,425 ) (2,013 ) (2,425 ) Total Adjustments 290 5,081 (624 ) 13,100 Adjusted EBITDA $ 58,526 $ 54,279 $ 169,694 $ 156,206 (1) Represents impairment charges recorded in the first and third quarters of 2023 of $0.9 million and $2.9 million, respectively, of an intangible asset associated with the exit of our commercial marketing business in the U.K. and operating lease right-of-use assets. (2) These are primarily third-party costs related to acquisitions and potential acquisitions, integration of acquisitions, and separation of discontinued businesses or divestitures. (3) These costs are mainly due to involuntary employee termination benefits for our officers, and employees who have been notified that they will be terminated as part of a business reorganization or exit. (4) These are exit costs associated with terminated leases or full office closures that we either (i) will continue to pay until the contractual obligations are satisfied but with no economic benefit to us, or (ii) paid upon termination and ceasing to use the leased facilities. (5) Pre-tax gain related to the 2023 divestiture of our U.S. commercial marketing business which include contingent gains realized in the first and the third quarter of 2024. Non-GAAP Diluted Earnings per Share Non-GAAP diluted earnings per share (“Non-GAAP Diluted EPS”) represents diluted U.S. GAAP earnings per share (“U.S. GAAP Diluted EPS”) excluding the impact of certain items noted above, amortization of intangible assets, and the related income tax effects. While these adjustments may be recurring and not infrequent or unusual, we do not consider these adjustments to be indicative of the performance of our ongoing operations. We believe that the supplemental adjustments provide additional useful information to investors. The following table presents a reconciliation of U.S. GAAP Diluted EPS to Non-GAAP Diluted EPS for the periods indicated. Three Months Ended Nine Months Ended September 30, September 30, 2024 2023 2024 2023 U.S. GAAP Diluted EPS $ 1.73 $ 1.25 $ 4.53 $ 3.19 Impairment of long-lived assets — 0.15 — 0.20 Acquisition and divestiture-related expenses 0.01 0.09 0.01 0.25 Severance and other costs related to staff realignment 0.02 0.03 0.06 0.23 Expenses related to facility consolidations and office closures (1) — 0.12 0.04 0.14 Pre-tax gain from divestiture of a business (0.02 ) (0.13 ) (0.11 ) (0.13 ) Amortization of intangibles 0.44 0.46 1.31 1.43 Income tax effects of the adjustments (2) (0.05 ) (0.16 ) (0.26 ) (0.50 ) Non-GAAP Diluted EPS $ 2.13 $ 1.81 $ 5.58 $ 4.81 (1) These are exit costs related to actual office closures (previously included in Adjusted EBITDA) and accelerated depreciation related to fixed assets for planned office closures. (2) Income tax effects were calculated using the effective tax rate, adjusted for certain discrete items, if any, of 13.8% and 21.7% for the three months ended September 30, 2024 and 2023, respectively, and 20.0% and 23.5% for the nine months ended September 30, 2024 and 2023, respectively. 24 LIQUIDITY AND CAPITAL RESOURCES Liquidity and Borrowing Capacity . In addition to cash and cash equivalents on hand and cash generated from operations, our primary source of liquidity is from our Credit Facility with a syndicate of multiple commercial banks, as described in “Note 5 – Debt” in the “Notes to Consolidated Financial Statements” in this Quarterly Report. The Credit Facility requires that we remain in compliance with certain financial and non-financial covenants (as defined by the Credit Agreement, see our Annual Report for additional details). As of September 30, 2024, we were in compliance with the covenants and we had $588.2 million available under the Credit Facility to fund our ongoing operations, future acquisitions, dividend payments, and share repurchase program. We have entered into floating-to-fixed interest rate swap agreements for a total notional value of $275.0 million to hedge a portion of our floating-rate Credit Facility. The swap agreements will expire in 2025 and 2028, respectively, and we may consider entering into additional swap agreements as these existing hedges expire. As of September 30, 2024, the percentage of our fixed-rate debt to floating-rate debt was 65%. There are other conditions, such as the ongoing wars in Ukraine and the Middle East, that create uncertainty in the global economy, which in turn may impact, among other things, our ability to generate positive cash flows from operations and our ability to successfully execute and fund key initiatives. However, our current belief is that the combination of internally generated funds, available bank borrowings, and cash and cash equivalents on hand will provide the required liquidity and capital resources necessary to fund ongoing operations, customary capital expenditures, quarterly cash dividends, share repurchases, and organic growth. Additionally, we continuously analyze our capital structure to ensure we have capital to fund future strategic acquisitions. We continuously monitor the state of the financial markets to assess the availability of borrowing capacity under the Credit Facility and the cost of additional capital from both debt and equity markets. At present, we believe we will be able to continue to access these markets at commercially reasonable terms and conditions if we need additional capital in the near term. Dividends. We have historically paid quarterly cash dividends to our shareholders of record at $0.14 per share. Total dividend payments during the nine months ended September 30, 2024 were $7.9 million. Cash dividends declared thus far in 2024 are as follows: Dividend Declaration Date Dividend Per Share Record Date Payment Date February 27, 2024 $ 0.14 March 22, 2024 April 12, 2024 May 2, 2024 $ 0.14 June 7, 2024 July 12, 2024 August 1 , 2024 $ 0.14 September 6, 2024 October 11, 2024 October 31, 2024 $ 0.14 December 6, 2024 January 10, 2025 Cash Flow. The following table sets forth our sources and uses of cash for the nine months ended September 30, 2024 and 2023: Nine Months Ended September 30, (in thousands) 2024 2023 Net Cash Provided by Operating Activities $ 76,184 $ 45,552 Net Cash Used in Investing Activities (13,574 ) (3,389 ) Net Cash Used in Financing Activities (64,598 ) (47,064 ) Effect of Exchange Rate Changes on Cash, Cash Equivalents, and Restricted Cash 174 (213 ) Decrease in Cash, Cash Equivalents, and Restricted Cash $ (1,814 ) $ (5,114 ) Cash provided by operating activities increased by $30.6 million to $76.2 million as a result of higher net income, the net favorable impact of working capital changes, including the timing of servicing the receivables sold to MUFG under the MRPA. See “Note 3 – Contract Receivables, Net” in the “Notes to Consolidated Financial Statements” in this Quarterly Report for additional details on the sale of receivables under the MRPA. Cash used in investing activities increased by $10.2 million due to the timing of acquisitions and cash received in connection with the 2023 divestiture of our U.S. commercial marketing business. Cash used in financing activities increased by $17.5 million due to increases in share repurchases and net repayments of our borrowings. 25 Item 3. Quantitative and Qualit ative Disclosures About Market Risk There have been no material changes in the disclosures discussed in the section entitled “Quantitative and Qualitative Disclosures About Market Risk” in Part II, Item 7A of our Annual Report. Item 4. Contr ols and Procedures Disclosure Controls and Procedures and Internal Controls Over Financial Reporting . Our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, have evaluated the effectiveness of the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act of 1934) and have concluded that as of September 30, 2024, our disclosure controls and procedures were effective. There have been no significant changes in our internal controls over financial reporting during the quarterly period covered by this report that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. 26 PART II. OTHER INFORMATION Item 1. Leg al Proceedings We are involved in various legal matters and proceedings arising in the ordinary course of business. While these matters and proceedings cause us to incur costs, including, but not limited to, attorneys’ fees, we currently believe that any ultimate liability arising out of these matters and proceedings will not have a material adverse effect on our financial position, results of operations, or cash flows. Item 1A. Ri sk Factors There have been no material changes in the risk factors discussed in the section entitled “Risk Factors” disclosed in Part I, Item 1A of our Annual Report. The risks described in our Annual Report are not the only risks that we encounter. Additional risks and uncertainties not currently known to us or that we currently deem immaterial may also materially adversely affect our business, financial condition, and/or operating results. Item 2. Unregistered Sales of Eq uity Securities, Use of Proceeds, and Issuer Purchases of Equity Securities Share Repurchase Program. One of the objectives of our share repurchase program has been to offset dilution resulting from our employee incentive plan. The timing and extent to which we repurchase our shares will depend upon market conditions and other corporate considerations, as may be considered in our sole discretion. Repurchases are funded from our existing cash balances and/or borrowings, and repurchased shares are held as treasury stock. During the three months ended September 30, 2024, we did not make any share repurchases under our share repurchase program. As of September 30, 2024, $67.2 million of repurchase authority remained available for share repurchases. Repurchases of Equity Securities. The following table summarizes the share repurchase activity for the three months ended September 30, 2024 for our share repurchase program and shares purchased in satisfaction of employee tax withholding obligations related to the settlement of restricted stock units. Period Total Number of Shares Purchased (1) Average Price Paid per Share Total Number of Shares Purchased as Part of Publicly Announced Plans or Programs Approximate Dollar Value of Shares that May Yet Be Purchased Under the Plans or Programs (2) July 1 - July 31 — $ — — $ 67,217,536 August 1 - August 31 2,383 $ 157.67 — $ 67,217,536 September 1 - September 30 — $ — — $ 67,217,536 Total 2,383 $ 157.67 — (1) The total number of shares purchased includes shares purchased from employees to pay required withholding taxes related to the settlement of restricted stock units in accordance with our applicable long-term incentive plan. During the three months ended September 30, 2024, we repurchased 2,383 shares of common stock from employees in satisfaction of tax withholding obligations at an average price of $157.67 per share. (2) The current share repurchase program authorizes share repurchases in the aggregate up to $200.0 million.
