CHARLES RIVER ASSOCIATES (CRA) REPORTS

FINANCIAL RESULTS FOR THE FIRST QUARTER OF 2026

Broad-based Contributions Drive Record Quarterly Revenue

BOSTON, May 7, 2026 – Charles River Associates (NASDAQ: CRAI), a worldwide leader in providing economic, financial and management consulting services, today announced financial results for the fiscal first quarter ended April 4, 2026.

“Maintaining the momentum of a record fiscal 2025, CRA continued its strong performance into the first quarter of fiscal 2026 as revenue increased by 10.5% year over year to $201.0 million,” said Paul Maleh, CRA’s President and Chief Executive Officer. “This represents the highest quarterly revenue in the company’s history, besting the previous record set by the fourth quarter of fiscal 2025.”

“Broad-based contributions drove the quarter’s strong performance, with eight practices growing year over year. Four practices—Energy, Finance, Forensic Services, and Life Sciences—posted double-digit revenue growth, while the Antitrust & Competition Economics practice posted a new high for quarterly revenue. This strong practice performance reflected balanced growth across our portfolio, as our Legal & Regulatory offerings grew 11.5% year over year and Management Consulting offerings expanded 8.3%. We also generated growth across our geographies, with our North American operations increasing revenue by 8.5% and our international operations expanding 20.3% year over year.”

Highlights for First Quarter Fiscal 2026

•Revenue grew 10.5% year over year to $201.0 million.

•Utilization was 77% and quarter-end headcount increased 2.5% year over year.

•Net income decreased 38.2% year over year to $11.1 million, or 5.5% of revenue, compared with $18.0 million, or 9.9% of revenue, in the first quarter of fiscal 2025; non-GAAP net income decreased 14.1% year over year to $13.1 million, or 6.5% of revenue, compared with $15.3 million, or 8.4% of revenue, in the first quarter of fiscal 2025.

•Earnings per diluted share decreased 35.5% year over year to $1.69 from $2.62 in the first quarter of fiscal 2025; non-GAAP earnings per diluted share decreased 10.4% year over year to $1.99 from $2.22 in the first quarter of fiscal 2025.

•Non-GAAP EBITDA decreased 6.5% to $23.2 million, or 11.5% of revenue, compared with $24.8 million, or 13.6% of revenue, in the first quarter of fiscal 2025.

•On a constant currency basis relative to the first quarter of fiscal 2025, revenue, GAAP net income, and earnings per diluted share would have been lower by $2.6 million, $0.2 million and $0.04 per diluted share, respectively. Non-GAAP net income, non-GAAP earnings per diluted share, and non-GAAP EBITDA would have been lower by $0.2 million, $0.04 per diluted share and $0.3 million, respectively.

•CRA returned $25.3 million of capital to its shareholders, consisting of $3.8 million of dividend payments and $21.5 million for share repurchases of approximately 116,000 shares.

Management Commentary and Financial Guidance

“We are reaffirming our financial guidance for full-year fiscal 2026 of revenue in the range of $785 million to $805 million and non-GAAP EBITDA margin in the range of 12.0% to 13.0%, both on a constant currency basis relative to fiscal 2025,” said Maleh. “We are encouraged by the strong start to the year, supportive market trends, and the continued replenishing of our sales pipeline. However, we remain mindful that evolving geopolitical, global macroeconomic, and business conditions can affect our business.”

CRA does not provide reconciliations of its annual non-GAAP EBITDA margin guidance to GAAP net income margin because the Company is unable to estimate with reasonable certainty and without unreasonable effort: (i) unusual gains or charges, foreign currency exchange rates and the resulting effect of these items on CRA’s taxes and (ii) the impact of equity awards on CRA’s taxes. These items are uncertain, depend on various factors, and may have a material effect on CRA’s results computed in accordance with

1

GAAP. A reconciliation between the historical GAAP and non-GAAP financial measures presented in this press release is provided in the financial tables at the end of this press release.

Quarterly Dividend

On May 7, 2026, CRA announced a quarterly cash dividend of $0.57 per common share, payable on June 12, 2026 to shareholders of record as of May 26, 2026. CRA expects to continue paying quarterly dividends, the declaration, timing and amounts of which remain subject to the discretion of CRA’s Board of Directors.

Conference Call Information and Prepared CFO Remarks

CRA will host a conference call today at 10:00 a.m. ET to discuss its first-quarter 2026 financial results. To listen to the live call, please
