CACI International Inc (NYSE: CACI) announced results today for its fiscal first quarter ended September 30, 2025.

“CACI’s exceptional start to fiscal year 2026 underscores our differentiated position in the market. We delivered strong financial results across the board, including robust free cash flow driven by double-digit revenue growth and strong profitability,” said John Mengucci, CACI President and Chief Executive Officer. “Our $5 billion of contract awards and growth in both total and funded backlog demonstrate our focus on critical, well-funded national security priorities. Our performance, along with our continued investments ahead of need, healthy pipeline, and strong customer demand signals, gives us increased confidence in our ability to deliver on our fiscal year 2026 commitments, achieve our three-year financial targets, and generate value for our customers and our shareholders.”

First Quarter Results

Revenues in the first quarter of fiscal year 2026 increased 11.2% year-over-year, driven by 5.5% organic growth. The increase in income from operations was driven by higher revenues and gross profit. Growth in diluted earnings per share and adjusted diluted earnings per share were driven by higher income from operations and share repurchases made during fiscal year 2025, partially offset by higher interest expense and a higher tax provision. The increase in cash from operations, excluding MARPA, was driven primarily by higher net income and strong working capital management.

First Quarter Contract Awards

Contract awards in the first quarter totaled $5.0 billion, with approximately 60% for new business to CACI. Awards exclude ceiling values of multi-award, indefinite delivery, indefinite quantity (IDIQ) contracts.

There are statements made herein that do not address historical facts and, therefore, could be interpreted to be forward-looking statements as that term is defined in the Private Securities Litigation Reform Act of 1995. Such statements are subject to risk factors that could cause actual results to be materially different from anticipated results. These risk factors include, but are not limited to, the following: our reliance on U.S. government contracts, which includes general risk around the government contract procurement process (such as bid protest, small business set asides, loss of work due to organizational conflicts of interest, etc.) and termination risks; significant delays or reductions in appropriations for our programs and broader changes in U.S. government funding and spending patterns; legislation that amends or changes discretionary spending levels or budget priorities, such as for homeland security or to address global pandemics; legal, regulatory, and political change from successive presidential administrations that could result in economic uncertainty; changes in U.S. federal agencies, current agreements with other nations, foreign events, or any other events which may affect the global economy, including the impact of global pandemics; the results of government audits and reviews conducted by the Defense Contract Audit Agency, the Defense Contract Management Agency, or other governmental entities with cognizant oversight; competitive factors such as pricing pressures and/or competition to hire and retain employees (particularly those with security clearances); failure to achieve contract awards in connection with re-competes for present business and/or competition for new business; regional and national economic conditions in the United States and globally, including but not limited to: terrorist activities or war, changes in interest rates, currency fluctuations, significant fluctuations in the equity markets, and market speculation regarding our continued independence; our ability to meet contractual performance obligations, including technologically complex obligations dependent on factors not wholly within our control; limited access to certain facilities required for us to perform our work, including during a global pandemic; changes in tax law, the interpretation of associated rules and regulations, or any other events impacting our effective tax rate; changes in technology; the potential impact of the announcement or consummation of a proposed transaction and our ability to successfully integrate the operations of our recent and any future acquisitions; our ability to achieve the objectives of near term or long-term business plans; the effects of health epidemics, pandemics and similar outbreaks may have material adverse effects on our business, financial position, results of operations and/or cash flows; and other risks described in our Securities and Exchange Commission filings.

Reconciliation of Net Income to Adjusted Net Income and Diluted EPS to Adjusted Diluted EPS (Unaudited)

Adjusted net income and adjusted diluted EPS are non-GAAP performance measures. We define adjusted net income and adjusted diluted EPS as GAAP net income and GAAP diluted EPS, respectively, excluding intangible amortization expense and the related tax impact as we do not consider intangible amortization expense to be indicative of our operating performance. We believe that these performance measures provide management and investors with useful information in assessing trends in our ongoing operating performance, provide greater visibility in understanding the long-term financial performance of the Company, and allow investors to more easily compare our results to results of our peers. These non-GAAP measures should not be considered in isolation or as a substitute for performance measures prepared in accordance with GAAP.

Reconciliation of Net Income to Earnings Before Interest, Taxes, Depreciation and Amortization (EBITDA) (Unaudited)

The Company views EBITDA and EBITDA margin, both of which are defined as non-GAAP measures, as important indicators of performance, consistent with the manner in which management measures and forecasts the Company’s performance. EBITDA is a commonly used non-GAAP measure when comparing our results with those of other companies. We define EBITDA as GAAP net income plus net interest expense, income taxes, and depreciation and amortization expense (including depreciation within direct costs). We consider EBITDA to be a useful metric for management and investors to evaluate and compare the ongoing operating performance of our business on a consistent basis across reporting periods, as it eliminates the effect of non-cash items such as depreciation of tangible assets and amortization of intangible assets primarily recognized in business combinations, which we do not believe are indicative of our operating performance. EBITDA margin is EBITDA divided by revenue. These non-GAAP measures should not be considered in isolation or as a substitute for performance measures prepared in accordance with GAAP.

Reconciliation of Net Cash Provided by Operating Activities to Net Cash Provided by Operating Activities Excluding MARPA and to Free Cash Flow (Unaudited)

The Company defines net cash provided by operating activities excluding MARPA, a non-GAAP measure, as net cash provided by operating activities calculated in accordance with GAAP, adjusted to exclude cash flows from CACI’s MARPA for the sale of certain designated eligible U.S. government receivables up to a maximum amount of $300.0 million. Free cash flow is a non-GAAP liquidity measure and may not be comparable to similarly titled measures used by other companies. The Company defines free cash flow as net cash provided by operating activities excluding MARPA, less payments for capital expenditures. The Company uses these non-GAAP measures to assess our ability to generate cash from our business operations and plan for future operating and capital actions. We believe these measures allow investors to more easily compare current period results to prior period results and to results of our peers. Free cash flow does not represent residual cash flows available for discretionary purposes and should not be used as a substitute for cash flow measures prepared in accordance with GAAP.
