Safe Harbor Regarding Forward Looking Statements This presentation contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Forward-looking statements are subject to risks, uncertainties and assumptions and are identified by words such as "expects," "future," "outlook," "anticipates," "believes," "could," "guidance," "should," "target," "may", "will," "plan" and other similar words. All statements addressing operating performance, events, or developments that Graham Corporation expects or anticipates will occur in the future, including but not limited to, profitability of future projects and the business, its ability to deliver to plan, its ability to continue to strengthen relationships with customers in the defense industry, its ability to secure future projects and applications, expected expansion and growth opportunities, anticipated sales, revenues, adjusted EBITDA, adjusted EBITDA margins, capital expenditures and SG&A expenses, the timing of conversion of backlog to sales, orders, market presence, profit margins, tax rates, tariffs, foreign sales operations, customer preferences, changes in market conditions in the industries in which it operates, changes in general economic conditions and customer behavior, forecasts regarding the timing and scope of the economic recovery in its markets, and its acquisition and growth strategy, are forward-looking statements. Because they are forward-looking, they should be evaluated in light of important risk factors and uncertainties. These risk factors and uncertainties are more fully described in Graham Corporation's most recent Annual Report filed with the Securities and Exchange Commission (the "SEC"), included under the heading entitled "Risk Factors", and in other reports filed with the SEC. Should one or more of these risks or uncertainties materialize or should any of Graham Corporation's underlying assumptions prove incorrect, actual results may vary materially from those currently anticipated. In addition, undue reliance should not be placed on Graham Corporation's forward-looking statements. Except as required by law, Graham Corporation disclaims any obligation to update or publicly announce any revisions to any of the forward-looking statements contained in this presentation. Use of Key Performance Indicators This presentation includes key performance indicators, such as orders, backlog, and book-to-bill ratio. See the slide entitled "Disclaimer Regarding Key Performance Metrics" in this presentation for information regarding these key performance indicators. Use of Non-GAAP Measures This presentation includes non-GAAP measures, such as Adjusted EBITDA, Adjusted EBITDA margin, Adjusted Net income (loss) and Adjusted Net income (loss) per diluted share. See the Appendix for information regarding these non-GAAP measures, including reconciliations to the most directly comparable U.S. GAAP financial measures. Use of Forward-Looking Non-GAAP Financial Measures Forward-looking ROIC, adjusted EBITDA and adjusted EBITDA margin are non-GAAP measures. The Company is unable to present a quantitative reconciliation of these forward-looking non-GAAP financial measures to their most directly comparable forward-looking GAAP financial measures because such information is not available, and management cannot reliably predict the necessary components of such GAAP measures without unreasonable effort largely because forecasting or predicting our future operating results is subject to many factors out of our control or not readily predictable. In addition, the Company believes that such reconciliations would imply a degree of precision that would be confusing or misleading to investors. The unavailable information could have a significant impact on the Company's fiscal 2025 financial results. These non-GAAP financial measures are preliminary estimates and are subject to risks and uncertainties, including, among others, changes in connection with purchase accounting, quarter-end, and year-end adjustments. Any variation between the Company's actual results and preliminary financial estimates set forth above may be material. Forward-looking ROIC is defined as a return on invested capital and is calculated by dividing net operating profit after taxes by the total invested capital. Forward-looking ROIC is not a measure determined in accordance with GAAP. Nevertheless, Graham believes that providing forward-looking ROIC is important for investors and other readers of Graham's financial statements, as it is used as an analytical indicator by Graham's management to better understand profitability and efficiency of use of capital for certain projects. Because forward-looking ROIC is a non-GAAP measure and is thus susceptible to varying calculations, forward-looking ROIC, as presented, may not be directly comparable to other similarly titled measures used by other companies.

Key Performance Indicators In addition to the non-GAAP measures used in this presentation, management uses the following key performance metrics to analyze and measure the Company's financial performance and results of operations: orders, backlog, and book-to-bill ratio. Management uses orders and backlog as measures of current and future business and financial performance, and these may not be comparable with measures provided by other companies. Orders represent written communications received from customers requesting the Company to provide products and/or services. Backlog is defined as the total dollar value of net orders received for which revenue has not yet been recognized. Management believes tracking orders and backlog are useful as it often times is a leading indicator of future performance. In accordance with industry practice, contracts may include provisions for cancellation, termination, or suspension at the discretion of the customer. Key Performance Metrics The book-to-bill ratio is an operational measure that management uses to track the growth prospects of the Company. The Company calculates the book-to-bill ratio for a given period as net orders divided by net sales. Given that each of orders, backlog, and book-to-bill ratio are operational measures and that the Company's methodology for calculating orders, backlog, and book-to-bill ratio does not meet the definition of a non-GAAP measure, as that term is defined by the U.S. Securities and Exchange Commission, a quantitative reconciliation for each is not required or provided.

Adjusted EBITDA margin is defined as Adjusted EBITDA as a percentage of sales. Adjusted EBITDA and Adjusted EBITDA margin are not measures determined in accordance with generally accepted accounting principles in the United States, commonly known as GAAP. Nevertheless, Graham believes that providing non-GAAP information, such as Adjusted EBITDA and Adjusted EBITDA margin, is important for investors and other readers of Graham's financial statements, as it is used as an analytical indicator by Graham's management to better understand operating performance. Moreover, Graham's credit facility also contains ratios based on Adjusted EBITDA. Because Adjusted EBITDA and Adjusted EBITDA margin are non-GAAP measures and are thus susceptible to varying calculations, Adjusted EBITDA, and Adjusted EBITDA margin, as presented, may not be directly comparable to other similarly titled measures used by other companies.

Adjusted net income and adjusted net income per diluted share are not measures determined in accordance with GAAP, and may not be comparable to the measures as used by other companies. Nevertheless, Graham believes that providing non-GAAP information, such as adjusted net income and adjusted net income per diluted share, is important for investors and other readers of the Company's financial statements and assists in understanding the comparison of the current quarter's and current fiscal year's net income and net income per diluted share to the historical periods' net income and net income per diluted share. Graham also believes that adjusted net income per share, which adds back intangible amortization expense related to acquisitions, provides a better representation of the cash earnings of the Company.
