Notes to Consolidated Financial Statements

(Unaudited)

(dollar amounts in tables in thousands, except share and per share data)

NOTE 1 – 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.

Software assets, which were previously included within “Property and equipment, net” and “Other assets” on the Company’s consolidated balance sheets, have been reclassified and consolidated under “Other intangible assets, net”. To conform to the current year’s presentation, $1.6 million and $21.8 million, as of December 31, 2024, have been reclassified from “Property and equipment, net” and “Other assets” to “Other intangible assets, net,” respectively.

Previously separate financial statement line items “Depreciation and amortization” and “Amortization of intangible assets” on the Company’s consolidated statements of comprehensive income have been combined under “Depreciation and amortization”.

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 the reported amounts of revenue and expenses. Key estimates include those that are 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. During the three and the six months ended June 30, 2025, the Company recognized $5.3 million and $11.6 million, respectively, in net income as a result of changes in estimates related to fixed-price contracts accounted for under the percentage-of-completion method.

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 six-month periods ended June 30, 2025 and 2024 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, 2024 and the notes thereto included in the Company’s Annual Report on Form 10-K.

Recent Accounting Pronouncements

Recent Accounting Pronouncements Not Yet Adopted

Income Taxes

In December 2023, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2023-09, Income Taxes: Improvements to Income Tax Disclosures (“ASU 2023-09”), 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 will be 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 expected to adopt the provisions of ASU 2023-09 for the fiscal year ending December 31, 2025, and, except for additional footnote disclosures, does not expect the adoption to have a material impact on the consolidated financial statements.

Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures

In November 2024, the FASB issued ASU 2024-03: Disaggregation of Income Statement Expenses (“ASU 2024-03”), which requires additional disaggregation of certain costs and expenses. ASU 2024-03 specifically requires all public entities to disclose within a tabular format the amounts of (a) purchases of inventory, (b) employee compensation, (c) depreciation, (d) intangible asset amortization, and (e) depreciation, depletion, and amortization recognized as part of oil- and gas-producing activities in each relevant expense caption as well as certain amounts that are already required to be disclosed under current U.S. GAAP. ASU 2024-03 also requires public entities to disclose a qualitative description of the composition of any amounts in relevant expense captions that are not separately disaggregated and the amount and definition of the entity’s selling expenses. ASU 2024-03 will be effective for the Company for the 2027 fiscal year and interim periods within the 2028 fiscal year, 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 2024-03 and, except for additional footnote disclosures, does not expect the adoption to have a material impact on the consolidated financial statements.

NOTE 2 – RESTRICTED CASH

The following table provides a reconciliation of cash, cash equivalents, and restricted cash as of June 30, 2025 and 2024 to cash, cash equivalents, and restricted cash shown in the consolidated statements of cash flows for the six months ended June 30, 2025 and 2024:

	June 30, 2025		June 30, 2024
Cash and cash equivalents	$	6,981	$	4,056
Restricted cash		19,907		712
Total of cash, cash equivalents, and restricted cash shown in the consolidated statements of cash flows	$	26,888	$	4,768

Restricted cash is primarily related to the Company’s energy incentive business with public utility clients and includes restricted cash from the acquisition of Applied Energy Group, Inc. (“AEG”).

Contract Assets and Liabilities

Contract assets consist of unbilled receivables on contracts where revenue recognized exceeds the amount billed. 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 June 30, 2025 and December 31, 2024:

	June 30, 2025			December 31, 2024
Contract assets	$	236,227		$	188,941
Contract liabilities		(23,913	)		(24,580	)
Net contract assets (liabilities)	$	212,314		$	164,361

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 six months ended June 30, 2025 and 2024, the Company recognized $17.5 million and $15.2 million in revenue related to the contract liabilities balance at December 31, 2024 and 2023, respectively.

12

Unfulfilled Performance Obligations

Unfulfilled performance obligations (“UPO”) were $0.8 billion and $1.3 billion as of June 30, 2025 and December 31, 2024, respectively. During the six months ended June 30, 2025, the Company received termination-for-convenience notifications pursuant to the executive orders issued by the Trump Administration or actions taken based on recommendations of the Department of Government Efficiency. As a result, the UPO as of June 30, 2025 reflects the impact of approximately $0.3 billion of UPO previously reported as of December 31, 2024.

The Company expects to recognize the remaining UPO as revenue of approximately 38% by December 31, 2025, 78% by December 31, 2026, and the remainder thereafter.

NOTE 7 – DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

At June 30, 2025, the Company had floating-to-fixed interest rate swap agreements for an aggregate notional amount of $175.0 million, of which $75.0 million will mature on February 28, 2028, $75.0 million will mature on June 27, 2028, and $25.0 million will mature on June 26, 2030. 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 13 – Fair Value” for the fair value of these swaps.

NOTE 8 – INCOME TAXES

A reconciliation of the Company’s statutory rate to the effective tax rate (the “ETR”) for the three and six months ended June 30, 2025 and 2024 is as follows:

	Three Months Ended June 30,						Six Months Ended June 30,
	2025			2024			2025			2024
Statutory tax rate		21.0	%		21.0	%		21.0	%		21.0	%
State taxes, net of federal benefit		6.1	%		6.0	%		6.1	%		6.0	%
IRC 987 regulations		—			—			(7.4	%)		—
Equity-based compensation		(0.3	%)		—			0.6	%		(2.4	%)
Uncertain tax position		3.2	%		2.3	%		3.2	%		2.3	%
Tax credits		(11.3	%)		(6.6	%)		(11.3	%)		(6.6	%)
Other		2.3	%		3.6	%		3.5	%		3.1	%
Effective tax rate		21.0	%		26.3	%		15.7	%		23.4	%

The decrease in the Company’s ETR for the three months ended June 30, 2025 compared to 2024 was primarily due to the increased Research and Experimentation tax credit in the second quarter of 2025 and the impact of foreign withholding taxes imposed upon a dividend distribution from our Canadian subsidiaries made during the second quarter of 2024.

The decrease in the Company’s ETR for the six months ended June 30, 2025 compared to 2024 was primarily due to an income tax benefit recognized in the first quarter of 2025 from tax planning implemented in connection with the “transitional rules” governing unrealized foreign exchange gains and losses derived from translation of the operations, assets and liabilities of non-U.S. qualified subsidiaries provided by recently finalized U.S. federal tax regulations under Section 987 (“IRC 987”) of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”). The regulations under IRC 987 are effective for the Company for tax years beginning after December 31, 2024, and require computation of a pre-transition foreign currency gain or loss to be included in the determination of future taxable income or loss and an analysis of the various elections available to taxpayers. Based on the Company’s current analysis of the regulations and the available election to amortize its pre-2025 cumulative unrealized foreign exchange gains and losses impacting U.S. taxation of foreign earnings under Subpart F of the Internal Revenue Code, the Company recognized a non-cash deferred income tax benefit of $4.5 million related to its election to amortize its pre-transition foreign currency losses against taxable income over ten years.

On July 4, 2025, President Trump signed into law the One Big Beautiful Bill Act (the “OB3 Act”). The OB3 Act makes permanent changes to certain key elements of the Tax Cuts and Jobs Act of 2017 (the “TCJA”), including 100% bonus depreciation, domestic research cost expensing, the business interest expense limitation and the repeal of various clean energy tax credits. As a result, the OB3 Act is expected to impact the Company’s income tax payables and deferred tax assets as of July 4, 2025, the date of enactment, which will be reflected on the Company’s interim financial statements as of and for the quarter ended September 30, 2025 and the annual financial statements as of and for the year ended December 31, 2025. The Company continues to evaluate the actual financial impact of the OB3 Act on its financial statements.

NOTE 11 – ACQUISITIONS AND DIVESTITURES

Acquisitions

Applied Energy Group, Inc.

On December 31, 2024, the Company completed the acquisition of AEG, an energy technology and advisory services company, for $59.9 million in cash consideration. AEG provides a suite of integrated technology and advisory solutions to electric and gas utilities, state and local governments, and state energy offices nationwide which enhances the Company’s service offering and client footprint.

As part of the allocation of the purchase consideration, the Company recorded the following:

Net working capital	$	3,842
Property and equipment		55
Customer-related intangibles		20,000
Developed technology		5,000
Trade names and trademarks		350
Other, net		48
Goodwill		30,574
Purchase consideration	$	59,869

Net working capital includes restricted cash of $5.4 million, accounts receivable of $4.4 million, contract assets of $2.6 million, accrued expenses of $6.6 million, accounts payable of $1.3 million, and other assets and liabilities of $0.7 million.

The allocation of the purchase consideration is pending the finalization of intangibles valuation, which is expected to be completed by the end of the third quarter of fiscal year 2025.

The estimated useful lives of acquired intangible assets are as follows:

Customer-related intangibles	6.0 years
Developed technology	4.0 years
Trade names and trademarks	3.5 months

The Company revised customer-related intangibles from an initial estimate of $21.0 million to $20.0 million and estimated useful life from 9.0 years to 6.0 years as a result of new information received during the quarter ended March 31, 2025. The Company also revised goodwill from an initial estimate of $30.2 million to $30.6 million, primarily as a result of the net working capital adjustments recorded during the quarter ended June 30, 2025.

The goodwill is attributable to the workforce of AEG and expected synergies with the Company. Goodwill has an indefinite life and is deductible for income tax purposes. The pro-forma impact of the acquisition is not material to the Company’s results of operations.

NOTE 14 – COMMITMENTS AND CONTINGENCIES

Letters of Credit and Guarantees

The Company had open standby letters of credit totaling $1.7 million and $1.6 million at June 30, 2025 and December 31, 2024, respectively. Open standby letters of credit reduce the Company’s borrowing capacity under the Credit Facility.

17

At June 30, 2025 and December 31, 2024, the Company had $8.1 million and $8.2 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.

NOTE 15 – SEGMENT INFORMATION

The Company provides a broad array of professional services to its clients across several markets, primarily within the U.S. The Company operates as a single reportable and operating segment because the chief operating decision maker (the “CODM”), which is the Chief Executive Officer, manages the business activities on a consolidated basis. Although the Company disaggregates revenue by client market and client type, it does not manage its business or allocate resources based on client market or client type.

The CODM assesses segment performance based on consolidated net income as reported on the Company’s consolidated statements of comprehensive income. The CODM uses consolidated net income to evaluate the Company’s performance against budgets and decide whether to use the profits to invest in the business, pay down debt, repurchase stock, pay dividends, or fund acquisitions. Asset information provided to the CODM is not used for the purpose of making decisions and assessing performance of the Company.

The segment revenue, significant segment expenses, and segment profit are as follows:

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 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 healthcare can be delivered effectively on a cross-jurisdiction basis; natural disaster relief and rebuild efforts; and ongoing homeland security threats. In the wake of the major hurricanes that devastated communities in Texas, Florida, North Carolina, Louisiana, the U.S. Virgin Islands, and Puerto Rico, and the impact of wildfires in Hawaii, Oregon, and southern California, the affected areas remain in various stages of evacuation, relief, and recovery efforts. We believe our prior and current experience with disaster relief and rebuild efforts, including after hurricanes Katrina and Rita and Superstorm Sandy, and the wildfires in Oregon, put us in a favorable position to continue to provide recovery and housing assistance, and environmental and infrastructure solutions, including disaster mitigation, on behalf of federal departments and agencies, state, territorial, and local jurisdictions, and regional agencies.

As the federal government sharpens its focus on efficiency, transparency, consolidation, and accountability, we see growth opportunities for ICF’s fit-for-purpose technology solutions. Our offerings are innovative, agile, scalable, and aligned with commercial best practices, delivering clear and measurable outcomes. By combining deep institutional knowledge of our clients’ markets and data with our proven expertise in AI, open source, cloud-native, and commercially off the shelf low-code and no-code platforms, we are able to deliver highly functional, cost-effective solutions that meet the evolving demands of our customers while driving greater value and impact for taxpayers.

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, gain access to or expand customer relationships, 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. 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, 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.

As discussed in Part II, Item 7 of our Annual Report, during the six months ended June 30, 2025, we received notices for termination-for-convenience pursuant to the recent executive orders issued by the Administration or actions by DOGE which resulted in a reduction of $418.2 million of our backlog. The revenue recognized in fiscal year 2024 from the contracts subject to these terminations represented approximately 6.4% of the total 2024 fiscal year revenue.

nm - not meaningful

Revenue. The decrease in revenue was driven by a reduction of $68.8 million from our U.S. federal government clients primarily as a result of terminated contracts during 2025 due to the Administration’s changing priorities and the actions recommended by DOGE, as well as the disruption of the typical U.S. federal government procurement cycle. This decline was offset by increases of $31.5 million, $0.9 million, and $0.6 million from our commercial, U.S. state and local government, and international government clients, respectively. The following were changes in revenue from our various client markets:

•Energy, Environment, Infrastructure, and Disaster Recovery client market revenues increased $15.2 million, or 6.5%, driven by increases of $29.6 million, $1.1 million, and $0.4 million from our commercial, U.S. state and local government, and international government clients, respectively, offset by a decrease of $15.8 million from our U.S. federal government clients.

•Health and Social Programs client market revenues decreased $37.1 million, or 18.9%, driven by decreases of $36.9 million, $0.7 million, and $0.1 million from our U.S. federal government, U.S. state and local government, and international government clients, respectively, offset by an increase of $0.7 million from our commercial clients.

•Security and Other Civilian & Commercial client market revenues decreased by $14.0 million, or 16.9%, driven by a decrease of $16.1 million from our U.S. federal government clients, offset by increases of $1.2 million, $0.5 million, and $0.3 million from our commercial, U.S. state and local government, and international government clients, respectively.

Revenue for the three months ended June 30, 2025 includes subcontractor and other direct costs, which decreased $20.5 million, or 15.5%, from the second quarter of 2024 and totaled $112.3 million and $132.8 million for the three months ended June 30, 2025 and 2024, respectively, and the margin on such costs.

21

Direct Costs. The decrease of $30.9 million in direct costs was primarily a result of terminated U.S. federal government contracts during 2025. For the three months ended June 30, 2025 and 2024, direct labor and related fringe benefit costs as a percentage of direct costs were 62.4% and 59.7%, respectively, and subcontractor and other direct costs as a percentage of direct costs were 37.6% and 40.3%, respectively. As a percentage of revenue, direct labor and related fringe benefit costs were 39.1% and 38.4%, respectively, and subcontractor and other direct costs were 23.6% and 25.9%, respectively, for the three months ended June 30, 2025 and 2024. Total direct costs as a percentage of revenue were 62.7% for the three months ended June 30, 2025, compared to 64.3% for the three months ended June 30, 2024.

Indirect and selling expenses. For the three months ended June 30, 2025, our indirect and selling expenses decreased by $4.1 million, or 3.2%, compared to the prior year, primarily as a result of a decrease of $4.6 million in general and administrative costs. The decrease in general and administrative costs was due, in part, to lower facilities expense as a result of facility consolidations in the fourth quarter of 2024. Our indirect and selling expenses as a percentage of revenue were 25.8% for the three months ended June 30, 2025, compared to 24.8% for the three months ended June 30, 2024.

Depreciation and amortization. Our depreciation and amortization for the three months ended June 30, 2025 was $5.5 million compared to $4.9 million for the three months ended June 30, 2024.

The increase in amortization of intangible assets acquired in business combinations was primarily due to the amortization of intangible assets acquired in our acquisition of Applied Energy Group (“AEG”) in the fourth quarter of 2024.

Interest, net. The increase of $0.7 million in interest, net, was primarily due to higher average debt balance of $542.2 million for the three months ended June 30, 2025 compared to $493.8 million for the same period in 2024. Use of floating-to-fixed interest rate swap agreements to hedge the variable interest portion of our debt reduced our interest expense by $0.2 million for the three months ended June 30, 2025 compared to a reduction of $1.7 million for the same period in 2024. Inclusive of the impact of the swap agreements, our interest rate was 5.6% for the three months ended June 30, 2025 compared to 5.3% for 2024.

Other (expense) income. Other (expense) income increased $1.7 million primarily due to an increase in unrealized foreign currency loss, resulting from depreciation of the U.S. dollar against the Euro and British pound, the principal currencies in which we transact. If the U.S. dollar experiences additional depreciation in 2025, we may incur additional foreign currency losses.

Provision for Income Taxes. Our effective income tax rate for the three months ended June 30, 2025 and 2024 was 21.0% and 26.3%, respectively. The difference was primarily due to the increased research and experimentation tax credit in the second quarter of 2025 and the impact of foreign withholding taxes imposed upon a dividend distribution from our Canadian subsidiaries made during the second quarter of 2024.

Revenue. The decrease in revenue of $42.7 million was driven by a reduction of $103.4 million from our U.S. federal government clients primarily as a result of terminated contracts in the first six months of 2025 due to the Administration’s changing priorities and the actions recommended by DOGE, as well as the disruption of the typical U.S. federal government procurement cycle. This decline was offset by increases of $57.5 million, $2.4 million, and $0.8 million from our commercial, international government, and U.S. state and local government clients, respectively. The following were changes in revenue from our various client markets:

•Energy, Environment, Infrastructure, and Disaster Recovery client market revenues increased $29.1 million, or 6.4%, driven by increases of $51.5 million and $1.3 million from our commercial and international government clients, respectively, offset by decreases of $22.6 million and $1.0 million from our U.S. federal government and U.S. state and local government clients, respectively.

•Health and Social Programs client market revenues decreased $59.0 million, or 15.2%, driven by a decrease of $61.5 million from our U.S. federal government clients, offset by increases of $1.5 million and $1.0 million from our commercial and U.S. state and local government clients, respectively.

•Security and Other Civilian & Commercial client market revenues decreased by $12.8 million, or 7.9%, driven by a decrease of $19.3 million from our U.S. federal government clients, offset by increases of $4.5 million, $1.1 million, and $0.8 million from our commercial, international government, and U.S. state and local government clients, respectively.

Revenue for the six months ended June 30, 2025 includes subcontractor and other direct costs, which decreased $30.4 million, or 12.0%, and totaled $222.9 million and $253.3 million for the six months ended June 30, 2025 and 2024, respectively, and the margin on such costs.

Direct Costs. The decrease of $38.9 million in direct costs was primarily a result of terminated U.S. federal government contracts during the first six months of 2025. For the six months ended June 30, 2025 and 2024, direct labor and related fringe benefit costs as a percentage of direct costs were 62.9% and 60.4%, respectively, and subcontractor and other direct costs as a percentage of direct costs were 37.1% and 39.6%, respectively. As a percentage of revenue, direct labor and related fringe benefit costs were 39.2% and 38.4%, respectively, and subcontractor and other direct costs were 23.1% and 25.2%, respectively, for the six months ended June 30, 2025 and 2024. Total direct costs as a percentage of revenue were 62.4% for the six months ended June 30, 2025, compared to 63.6% for the six months ended June 30, 2024.

23

Indirect and selling expenses. For the six months ended June 30, 2025, our indirect and selling expenses decreased by $1.3 million, or 0.5%, compared to the prior year, as a result of a decrease of $4.5 million in general and administrative costs, offset by an increase of $3.2 million in indirect labor and related fringe benefit costs. The decrease in general and administrative costs was due, in part, to lower facilities expense as a result of facility consolidations in the fourth quarter of 2024. The increase in indirect labor and related fringe benefit costs was due in part to the impact of severance in the current period. Our indirect and selling expenses as a percentage of revenue were 26.4% for the six months ended June 30, 2025, compared to 25.5% for the six months ended June 30, 2024.

Depreciation and amortization. Our depreciation and amortization for the six months ended June 30, 2025 was $10.8 million which is comparable to depreciation and amortization of $10.5 million for the six months ended June 30, 2024.

The increase in amortization of intangible assets acquired in business combinations was primarily due to the amortization of intangible assets acquired in our acquisition of AEG in the fourth quarter of 2024.

Interest, net. Our interest, net, for the six months ended June 30, 2025 was $15.8 million which is comparable to interest, net, of $15.9 million for the six months ended June 30, 2024. Use of floating-to-fixed interest rate swap agreements to hedge the variable interest portion of our debt decreased our interest expense by $0.9 million for the six months ended June 30, 2025 compared to a reduction of $3.3 million for the same period in 2024. Inclusive of the impact of the swap agreements, our interest rate was 5.4% for the six months ended June 30, 2025 compared to 5.5% for 2024.

Other (expense) income. Other (expense) income increased $4.4 million year-over-year primarily due to $2.8 million in unrealized foreign currency loss, resulting from depreciation of the U.S. dollar against the Euro and British pound, the principal currencies in which we transact, and $1.7 million gain from divestiture of our commercial marketing business during 2024. If the U.S. dollar experiences additional depreciation in 2025, we may incur additional foreign currency losses.

Provision for Income Taxes. Our effective income tax rate for the six months ended June 30, 2025 and 2024 was 15.7% and 23.4%, respectively. The difference was primarily due to an income tax benefit of $4.5 million recognized in the first quarter of 2025 from tax planning implemented in connection with the “transitional rules” governing unrealized foreign exchange gains and losses derived from translation of operations, assets, and liabilities of non-U.S. qualified subsidiaries provided by recently finalized U.S. federal tax regulations under IRC 987.

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. (“non-GAAP”) to their most comparable U.S. GAAP measures. 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.

The following table presents a reconciliation of net income to EBITDA and Adjusted EBITDA for the periods indicated.

	Three Months Ended					Six Months Ended
	June 30,					June 30,

Adjusted EBITDA	$	52,875		$	56,013	$	108,073		$	111,168

(1)These are primarily third-party costs related to acquisitions and integration of acquisitions.

(2)These costs are due to involuntary employee termination benefits for (i) our officers and (ii) group of employees who have been notified that they will be terminated as part of a business reorganization or exit.

(3)These charges and adjustments are related to a previously exited leased facility which we will continue to pay until the contractual obligations are satisfied but with no economic benefit to us, and the closure of certain international offices.

(4)Pre-tax gain related to the 2023 divestiture of our U.S. commercial marketing business which includes contingent gains realized in the first 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 acquired 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						Six Months Ended
	June 30,						June 30,
	2025			2024			2025			2024
U.S. GAAP Diluted EPS	$	1.28		$	1.36		$	2.72		$	2.80
Acquisition and divestiture-related expenses		—			—			0.01			—
Severance and other costs related to staff realignment		—			0.02			0.14			0.04
Charges and adjustments related to facility consolidations and office closures (1)		(0.02	)		—			(0.01	)		0.04

Income tax effects of the adjustments (3)		(0.10	)		(0.13	)		(0.26	)		(0.21	)
Non-GAAP Diluted EPS	$	1.66		$	1.69		$	3.61		$	3.46

(1)These are office closure charges and adjustments previously included in Adjusted EBITDA and accelerated depreciation related to fixed assets for planned office closures.

(2)The amortization of intangible assets acquired from business combinations totaled $9.2 million and $8.3 million for the three months ended June 30, 2025 and 2024, respectively, and $18.7 million and $16.6 million for the six months ended June 30, 2025 and 2024, respectively.

(3)Income tax effects were calculated using the effective tax rate, adjusted for certain discrete items, if any, of 21.0% and 26.3% for the three months ended June 30, 2025 and 2024, respectively, and 23.1% and 23.4% for the six months ended June 30, 2025 and 2024, respectively.

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 “Note 10 – Long-Term Debt” in the “Notes to Consolidated Financial Statements” in our Annual Report for additional details). As of June 30, 2025, we were in compliance with these covenants, and we had $488.3 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 $175.0 million to hedge a portion of our floating-rate Credit Facility, of which $150.0 million in swaps will expire in 2028 and the remaining $25.0 million will expire in 2030. We may consider entering into additional swap agreements before these existing hedges expire. As of June 30, 2025, the percentage of our fixed-rate debt to floating-rate debt was 38%.

There are other conditions, such as the ongoing wars in Ukraine and the Middle East and volatility in global trade (including the imposition of tariffs), 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 borrowing capacity, 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 on commercially reasonable terms and conditions if we need additional capital in the near term.

Dividends. We have historically paid quarterly cash dividends to our stockholders of record at $0.14 per share. Total dividend payments during the six months ended June 30, 2025 were $5.2 million.

Cash dividends declared thus far in 2025 are as follows:

Dividend Declaration Date	Dividend Per Share		Record Date	Payment Date
February 27, 2025	$	0.14	March 28, 2025	April 14, 2025
May 1, 2025	$	0.14	June 6, 2025	July 11, 2025
July 31, 2025	$	0.14	September 5, 2025	October 10, 2025

Cash Flow. The following table sets forth our sources and uses of cash for the six months ended June 30, 2025 and 2024:

	Six Months Ended
	June 30,
(in thousands)	2025			2024
Net Cash Provided by Operating Activities	$	18,923		$	50,635
Net Cash Used in Investing Activities		(8,799	)		(8,677	)
Net Cash Used in Financing Activities		(3,544	)		(46,508	)
Effect of Exchange Rate Changes on Cash, Cash Equivalents, and Restricted Cash		1,491			(131	)
Net Change in Cash, Cash Equivalents, and Restricted Cash	$	8,071		$	(4,681	)

Cash provided by operating activities was impacted by the timing of invoicing our customers, subsequent collection of cash, paying our vendors, and by the profitability of our contracts.

The change in cash used in financing activities of $43.0 million was primarily due to increased net borrowings from our Credit Facility and short-term financing, partially offset by an increase in share repurchases during the six months ended June 30, 2025.

PART II. OTHER INFORMATION

Item 1. Legal 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. Risk 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.

Item 2. Unregistered Sales of Equity 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 the approval by our board of directors, 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 June 30, 2025, we repurchased 31,339 shares under our share repurchase program at an aggregate purchase price of $2.5 million. As of June 30, 2025, $111.7 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 June 30, 2025 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)
April 1 - April 30		15,180	$	79.28		15,180	$	113,030,862
May 1 - May 31		16,193	$	79.69		16,159	$	111,742,998
June 1 - June 30		—	$	—		—	$	111,742,998
Total		31,373	$	79.49		31,339

(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 June 30, 2025, we repurchased 34 shares of common stock from employees in satisfaction of tax withholding obligations at an average price of $86.08 per share.

(2)The current share repurchase program authorizes share repurchases in the aggregate up to $300.0 million. Our Credit Facility permits annual share repurchases of at least $25.0 million; provided, that the Company is not in default of its covenants, and higher amounts provided that our Consolidated Leverage Ratio prior to and after giving effect to such repurchases is 0.50 to 1.00 less than the then-applicable maximum Consolidated Leverage Ratio and subject to a net liquidity of $100.00 million.

Item 3. Defaults Upon Senior Securities

None.

Item 4. Mine Safety Disclosures

Not applicable.

Item 5. Other Information

On May 27, 2025, James Morgan, our Chief Operating Officer, modified a Rule 10b5-1(c) trading plan, which was previously adopted on December 7, 2024.
