Disclaimer November 2025 Ampco-Pittsburgh Investor Presentation Forward-Looking Statements – The Private Securities Litigation Reform Act of 1995 (the "Act") provides a safe harbor for forward-looking statements made by us or on behalf of Ampco-Pittsburgh Corporation and its subsidiaries (collectively, "we," "us," "our," or the "Corporation"). This presentation may include, but is not limited to, statements about operating performance, trends and events the Corporation expects or anticipates will occur in the future, statements about sales and production levels, timing of orders for products, restructurings, the impact from pandemics and geopolitical conflicts, profitability and anticipated expenses, inflation, the global supply chain, the continued impact of tariffs, global trade conditions, and cash outflows. All statements in this document other than statements of historical fact are statements that are, or could be, deemed "forward-looking statements" within the meaning of the Act and words such as "may," "will," "intend," "believe," "expect," "anticipate," "estimate," "project," "target," "goal," "forecast," and other terms of similar meaning that indicate future events and trends are also generally intended to identify forward-looking statements. Forward-looking statements speak only as of the date on which such statements are made, are not guarantees of future performance or expectations, and involve risks and uncertainties. For the Corporation, these risks and uncertainties include, but are not limited to: inability to maintain adequate liquidity to meet our operating cash flow requirements, repay maturing debt and meet other financial obligations as they become due; economic downturns, cyclical demand for our products and insufficient demand for our products; excess global capacity in the steel industry; inability to successfully restructure our operations and/or invest in operations that will yield the best long-term value to our shareholders; changes in the global economic environment, inflation, the ongoing impact of tariffs, elevated interest rates, recessions or prolonged periods of slow economic growth, global instability, and actual and threatened geopolitical conflict, liability of our subsidiaries for claims alleging personal injury from exposure to asbestos-containing components historically used in certain products of our subsidiaries; inability to obtain necessary capital or financing on satisfactory terms to acquire capital expenditures that may be necessary to support our growth strategy; inoperability of certain equipment on which we rely; increases in commodity prices or insufficient hedging against increases in commodity prices, reductions in electricity and natural gas supply or shortages of key production materials for us or our customers; inability to satisfy the continued listing requirements of the New York Stock Exchange; potential attacks on information technology infrastructure and other cyber-based business disruptions; fluctuations in the value of the U.S. dollar relative to other currencies; changes in the existing regulatory environment; consequences of pandemics and geopolitical conflicts; work stoppage or another industrial action on the part of any of our unions; failure to maintain an effective system of internal control; and those discussed more fully elsewhere, particularly in Item 1A, Risk Factors, in Part I of the Corporation's latest Annual Report on Form 10-K and Part II of subsequent Quarterly Reports on Form 10-Q. The Corporation cannot guarantee any future results, levels of activity, performance or achievements. In addition, there may be events in the future that we are not able to predict accurately or control which may cause actual results to differ materially from expectations expressed or implied by forward-looking statements. Except as required by applicable law, we assume no obligation, and disclaim any obligation, to update forward-looking statements whether as a result of new information, events or otherwise. Additionally, as it relates to the insolvency proceedings of Union Electric Steel UK Limited ("UES-UK"), an indirect wholly owned subsidiary of the Corporation, any forward-looking statements are subject to risks and uncertainties related to such proceedings, including but not limited to: the actions of the certain insolvency practitioners of FRP Advisory Trading Limited ("FRP") as administrators of UES-UK (collectively, the "Administrators") and the High Court of Justice, Business and Property Courts at Leeds (the "Insolvency Court"); the interpretation and application of U.K. insolvency law; potential claims by creditors or other stakeholders; the ability to recover assets; and the broader impact on the Corporation's condensed consolidated financial condition, results of operations, and strategic plans.

Disclaimer, cont'd November 2025 Ampco-Pittsburgh Investor Presentation Industry Information - Unless otherwise indicated, information contained in this presentation concerning the Corporation's industry, competitive position and the markets in which it operates is based on information from independent and research organizations, other third-party sources and management estimates. Management estimates are derived from publicly available information released by independent industry analysts and other third-party sources, as well as data from the Corporation's internal research, and are based on assumptions made by the Corporation upon reviewing such data, and the Corporation's experience in, and knowledge of, such industry and markets, which the Corporation believes to be reasonable. In addition, projections, assumptions and estimates of the future performance of the industry in which the Corporation operates, and the Corporation's future performance are necessarily subject to uncertainty and risk due to a variety of factors, which could cause results to differ materially from those expressed in the estimates made by the independent parties and by the Corporation. Trademarks - This presentation may contain trademarks, service marks, trade names and copyrights of other companies, which are the property of their respective owners. Solely for convenience, some of the trademarks, service marks, trade names and copyrights referred to in this presentation may be listed without the TM, SM,© or® symbols, but we will assert, to the fullest extent under applicable law, the rights of the applicable owners, if any, to these trademarks, service marks, trade names and copyrights. Non-GAAP Financial Measures – The Corporation presents non-GAAP adjusted EBITDA, non-GAAP net debt and non-GAAP net debt to adjusted EBITDA ratio. Non-GAAP adjusted EBITDA is calculated as net income (loss) excluding interest expense, other expense (income) - net, income tax provision, depreciation and amortization, and stock-based compensation along with significant charges or credits that are one-time charges or credits, unrelated to the Corporation's ongoing results of operations, or beyond its control. Non-GAAP net debt is calculated as total debt less cash and cash equivalents. Non-GAAP net debt to adjusted EBITDA ratio is non-GAAP net debt divided by non-GAAP adjusted EBITDA. These non-GAAP financial measures are not based on any standardized methodology prescribed by accounting principles generally accepted in the United States of America ("GAAP"). The Corporation has presented non-GAAP adjusted EBITDA because it is a key measure used by the Corporation's management and Board of Directors to understand and evaluate the operating performance of the Corporation and its segments. While this non-GAAP measure may not be directly comparable to similarly titled measures presented by other companies, the Corporation's management and Board of Directors believes this non-GAAP measure enhances comparability to companies in its stated industry peer group. The Corporation has presented non-GAAP net debt and non-GAAP net debt to adjusted EBITDA ratio because the Corporation's management believes these metrics are common investor metrics which enhance comparability to companies in its stated industry peer group. The Corporation believes these non-GAAP financial measures help identify underlying trends in its business that otherwise could be masked by the effect of the items it excludes from adjusted EBITDA. The Corporation also believes these non-GAAP financial measure provides useful information to management, shareholders and investors, and others in understanding and evaluating its operating results, enhancing the overall understanding of its past performance and future prospects and allowing for greater transparency with respect to key financial metrics used by the Corporation's management in its financial and operational decision-making. In particular, the Corporation believes the exclusion of the foreign energy credit received, the change in employee benefit policy, refund of excess COVID-19 subsidies, receipt of employee-retention credits, severance and other exit costs, and asbestos-related charges (benefits) can provide a useful measure for period-to-period comparisons of the Corporation's core business performance. Non-GAAP adjusted EBITDA, non-GAAP net debt and non-GAAP net debt to adjusted EBITDA ratio are not prepared in accordance with GAAP and should not be considered in isolation of, or as an alternative to, measures prepared in accordance with GAAP. There are limitations related to the use of non-GAAP adjusted EBITDA, non-GAAP net debt and non-GAAP net debt to adjusted EBITDA ratio, rather than net income (loss), total debt or total debt to net income (loss) ratio which are the nearest GAAP equivalents. Among other things, there can be no assurance that additional expenses similar to the foreign energy credit received, the change in employee benefit policy, refund of excess COVID-19 subsidies, receipt of employee-retention credits, severance and other exit costs, and asbestos-related charges (benefits) will not occur in future periods.
