stoneridge.com © 2025 Q1 2025 Results 2 Non-GAAP Financial Measures This presentation contains information about the Company’s financial results that is not presented in accordance with accounting principles generally accepted in the United States (“GAAP”). Such non-GAAP financial measures are reconciled to their closest GAAP financial measures at the end of this presentation. The provision of these non-GAAP financial measures for 2025 and 2024 is not intended to indicate that Stoneridge is explicitly or implicitly providing projections on those non-GAAP financial measures, and actual results for such measures are likely to vary from those presented. The reconciliations include all information reasonably available to the Company at the date of this presentation and the adjustments that management can reasonably predict. Management believes the non-GAAP financial measures used in this presentation are useful to both management and investors in their analysis of the Company’s financial position and results of operations. In particular, management believes that adjusted gross profit and margin, adjusted operating income (loss) and margin, adjusted income (loss) before tax, adjusted net income (loss), adjusted EBITDA, adjusted EBITDA margin, adjusted net debt, adjusted debt, adjusted cash and free cash flow are useful measures in assessing the Company’s financial performance by excluding certain items that are not indicative of the Company’s core operating performance or that may obscure trends useful in evaluating the Company’s continuing operating activities. Management also believes that these measures are useful to both management and investors in their analysis of the Company’s results of operations and provide improved comparability between fiscal periods. Adjusted gross profit and margin, adjusted operating income (loss) and margin, adjusted income (loss) before tax, adjusted net income (loss), adjusted EBITDA, adjusted EBITDA margin, adjusted net debt, adjusted debt, adjusted cash and free cash flow should not be considered in isolation or as a substitute for gross profit, operating income (loss), income (loss) before tax, net income (loss), debt, cash and cash equivalents, cash provided by operating activities or other income statement or cash flow statement data prepared in accordance with GAAP.

stoneridge.com © 2025 Q1 2025 Results 3 Forward-Looking Statements Statements in this presentation that are not historical facts are forward-looking statements, which involve risks and uncertainties that could cause actual events or results to differ materially from those expressed in or implied by these statements. Important factors that could cause actual results to differ materially from those in the forward-looking statements include, among other factors, the ability of our suppliers to supply us with parts and components at competitive prices on a timely basis, including the impact of potential tariffs and trade considerations on their operations and output; fluctuations in the cost and availability of key materials and components (including semiconductors, printed circuit boards, resin, aluminum, steel and copper) and our ability to offset cost increases through negotiated price increases with our customers or other cost reduction actions, as necessary; global economic trends, competition and geopolitical risks, including impacts from ongoing or potential global conflicts and any related sanctions and other measures, or an escalation of sanctions, tariffs or other trade tensions between the U.S. and other countries; tariffs specifically in countries where we have significant direct or indirect manufacturing or supply chain exposure and our ability to either mitigate the impact of tariffs or pass any incremental costs to our customers; our ability to achieve cost reductions that offset or exceed customer-mandated selling price reductions; the reduced purchases, loss, financial distress or bankruptcy of a major customer or supplier; the costs and timing of business realignment, facility closures or similar actions; a significant change in commercial, automotive, off-highway or agricultural vehicle production; competitive market conditions and resulting effects on sales and pricing; foreign currency fluctuations and our ability to manage those impacts; customer acceptance of new products; our ability to successfully launch/produce products for awarded business; adverse changes in laws, government regulations or market conditions, affecting our products, our suppliers, or our customers’ products; liabilities arising from warranty claims, product recall or field actions, product liability and legal proceedings to which we are or may become a party, or the impact of product recall or field actions on our customers; labor disruptions at Stoneridge’s facilities or at any of Stoneridge significant customers or suppliers; the amount of Stoneridge’s indebtedness and the restrictive covenants contained in the agreements governing its indebtedness, including its revolving Credit Facility; capital availability or costs, including changes in interest rates; the occurrence or non-occurrence of circumstances beyond Stoneridge’s control; and the items described in “Risk Factors” and other uncertainties or risks discussed in Stoneridge’s periodic and current reports filed with the Securities and Exchange Commission. Important factors that could cause the performance of the commercial vehicle and automotive industry to differ materially from those in the forward-looking statements include factors such as (1) continued economic instability or poor economic conditions in the United States and global markets, (2) changes in economic conditions, housing prices, foreign currency exchange rates, commodity prices, including shortages of and increases or volatility in the price of oil, (3) changes in laws and regulations, (4) the state of the credit markets, (5) political stability, (6) international conflicts and (7) the occurrence of force majeure events. These factors should not be construed as exhaustive and should be considered with the other cautionary statements in Stoneridge’s filings with the Securities and Exchange Commission. Forward-looking statements are not guarantees of future performance; Stoneridge’s actual results of operations, financial condition and liquidity, and the development of the industry in which Stoneridge operates may differ materially from those described in or suggested by the forward-looking statements contained in this presentation. In addition, even if Stoneridge’s results of operations, financial condition and liquidity, and the development of the industry in which Stoneridge operates are consistent with the forward-looking statements contained in this presentation, those results or developments may not be indicative of results or developments in subsequent periods. This presentation contains time-sensitive information that reflects management’s best analysis only as of the date of this presentation. Any forward-looking statements in this presentation speak only as of the date of this presentation, and Stoneridge undertakes no obligation to update such statements. Comparisons of results for current and any prior periods are not intended to express any future trends or indications of future performance, unless expressed as such, and should only be viewed as historical data Stoneridge does not undertake any obligation to publicly update or revise any forward-looking statement as a result of new information, future events or otherwise, except as otherwise required by law. Rounding Disclosure: There may be slight immaterial differences between figures represented in our public filings compared to what is shown in this presentation.
