stoneridge.com © 2026 Full-Year & Q4 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 earnings (loss) per share, adjusted EBITDA, adjusted EBITDA margin, adjusted tax expense (benefit), 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 earnings (loss) per share, adjusted EBITDA, adjusted EBITDA margin, adjusted tax expense (benefit), 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), earnings per share, tax expense (benefit), debt, cash and cash equivalents, cash provided by operating activities or other income statement or cash flow statement data prepared in accordance with GAAP.
