Adjusted EBITDA margin is a non-GAAP financial measure. See Reconciliation of Net Income Attributable to ALGC to Adjusted EBITDA and non-GAAP measures below. 2Composed of 4,186,062 limited liability company units of Cardinal Civil Contracting Holdings LLC and an equal number of shares of Cardinal Class B common stock, and 345,666 of Cardinal Class A common stock. 3The preliminary estimated financial results for the year ended December 31, 2025, are based on currently available information and reflect Cardinal's current estimates and assessments. Cardinal has not completed its full year financial closing procedures and controls and governance procedures, and its independent registered public accounting firm has not completed any audit, review or set of procedures with respect to the preliminary estimated financial results and has not expressed any opinion or any other form of assurance with respect thereto. Actual reported results may differ materially from the preliminary results presented as a result of the completion of Cardinal's financial closing procedures and controls. These preliminary estimated financial results should not be viewed as a substitute for Cardinal's full audited financial statements prepared in accordance with GAAP. Accordingly, you should not place undue reliance on these preliminary estimated financial results. 4Adjusted EBITDA margin is a non-GAAP financial measure. Cardinal is unable provide the most directly comparable GAAP financial measure or a quantitative reconciliation thereto without unreasonable effort. See &#34;Non-GAAP Measures&#34; below. 5Guidance reflects an estimated 10.5‑month contribution from ALGC.Important Information for Investors and StockholdersNon-GAAP MeasuresThis press release includes a discussion of Adjusted EBITDA and Adjusted EBITDA margin, which are &#34;non-GAAP&#34; financial measures as defined in Regulation G under the Securities Exchange Act of 1934. Cardinal and ALGC report financial results in accordance with U.S. generally accepted accounting principles (&#34;GAAP&#34;) but believe that certain non-GAAP financial measures provide useful supplemental information to investors regarding the underlying business trends and performance of their respective ongoing operations and is useful for period-over-period comparisons of those operations. Non-GAAP measures should be used in addition to, and not in lieu of, results prepared in conformity with GAAP.Cardinal is not able to provide the most directly comparable GAAP financial measure, or a quantitative reconciliation thereto, for the forward-looking guidance of estimated Adjusted EBITDA Margin without unreasonable effort due to the inherent uncertainty and difficulty in predicting the timing and amount of certain items, including but not limited to amortization of intangible assets and depreciation, which may be significant and difficult to project with a reasonable degree of accuracy, as the allocation of purchase price to intangible assets and property and equipment has not yet been performed. Because these adjustments are inherently variable and uncertain and depend on various factors that are beyond Cardinal's control, Cardinal is also unable to predict their probable significance. The variability of these items could have an unpredictable, and potentially significant, impact on Cardinal's future GAAP financial results.Reconciliation of Net Income Attributable to ALGC to Adjusted EBITDA <div><table><tbody><tr><td colspan="1" rowspan="1">$ in Thousands Unaudited</td><td colspan="2" rowspan="1">Trailing 12 Months Ended September 30, 2025</td><td colspan="1" rowspan="1"> </td><td colspan="1" rowspan="1"> </td></tr><tr><td colspan="1" rowspan="1">Revenue</td><td colspan="1" rowspan="1">$</td><td colspan="1" rowspan="1">159,851</td><td colspan="1" rowspan="1"> </td><td colspan="1" rowspan="1"> </td></tr><tr><td colspan="1" rowspan="1">Net income</td><td colspan="1" rowspan="1"> </td><td colspan="1" rowspan="1">33,347</td><td colspan="1" rowspan="1"> </td><td colspan="1" rowspan="1"> </td></tr><tr><td colspan="1" rowspan="1">Interest expense, net</td><td colspan="1" rowspan="1"> </td><td colspan="1" rowspan="1">46</td><td colspan="1" rowspan="1"> </td><td colspan="1" rowspan="1"> </td></tr><tr><td colspan="1" rowspan="1">Income tax expense</td><td colspan="1" rowspan="1"> </td><td colspan="1" rowspan="1">1,489</td><td colspan="1" rowspan="1"> </td><td colspan="1" rowspan="1"> </td></tr><tr><td colspan="1" rowspan="1">Depreciation and amortization expense</td><td colspan="1" rowspan="1"> </td><td colspan="1" rowspan="1">7,138</td><td colspan="1" rowspan="1"> </td><td colspan="1" rowspan="1"> </td></tr><tr><td colspan="1" rowspan="1">EBITDA</td><td colspan="1" rowspan="1">$</td><td colspan="1" rowspan="1">42,020</td><td colspan="1" rowspan="1"> </td><td colspan="1" rowspan="1"> </td></tr><tr><td colspan="1" rowspan="1">Other</td><td colspan="1" rowspan="1"> </td><td colspan="1" rowspan="1">-</td><td colspan="1" rowspan="1"> </td><td colspan="1" rowspan="1"> </td></tr><tr><td colspan="1" rowspan="1">Adjusted EBITDA</td><td colspan="1" rowspan="1">$</td><td colspan="1" rowspan="1">42,020</td><td colspan="1" rowspan="1"> </td><td colspan="1" rowspan="1"> </td></tr><tr><td colspan="1" rowspan="1">Net Income Margin</td><td colspan="1" rowspan="1"> </td><td colspan="1" rowspan="1">20.9</td><td colspan="1" rowspan="1">%</td><td colspan="1" rowspan="1"> </td></tr><tr><td colspan="1" rowspan="1">EBITDA Margin</td><td colspan="1" rowspan="1"> </td><td colspan="1" rowspan="1">26.3</td><td colspan="1" rowspan="1">%</td><td colspan="1" rowspan="1"> </td></tr><tr><td colspan="1" rowspan="1">Adjusted EBITDA Margin</td><td colspan="1" rowspan="1"> </td><td colspan="1" rowspan="1">26.3</td><td colspan="1" rowspan="1">%</td><td colspan="1" rowspan="1"> </td></tr></tbody></table></div>Supplemental PresentationCautionary Statement Regarding Forward-Looking StatementsThis press release contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 concerning, among other things, Cardinal Infrastructure Group, Inc.'s (&#34;Cardinal&#34;) acquisition (the &#34;ALGC Acquisition&#34;) of A.L.
