ITEM 2.02 Results of Operations and Financial Condition.

On May 7, 2026, Stoneridge, Inc. (the “Company”) issued a press release announcing its results for the first quarter ended March 31, 2026. A copy of the press release is attached hereto as Exhibit 99.1. On May 7, 2026, members of the Company’s senior management will hold the first quarter 2026 earnings conference call via webcast to discuss the Company’s financial results and the presentation attached hereto as Exhibit 99.2, will accompany management’s comments.

The press release and earnings conference call presentation contain certain non-GAAP financial measures, including Adjusted Gross Profit and Margin, Adjusted Operating Income (Loss) and Margin, Adjusted Income (Loss) Before Tax, Adjusted Tax Expense (Benefit), Adjusted Net Loss From Continuing Operations, Adjusted Net Income (Loss), Adjusted Loss per Share (“Adjusted EPS”), Earnings Before Interest, Taxes, Depreciation and Amortization (“EBITDA”), Adjusted EBITDA and Margin, and Net Debt (collectively, the “Non-GAAP Financial Measures”). Management believes that the presentation of the Non-GAAP Financial Measures used in the press release and earnings conference call presentation are useful to both management and investors in their analysis of the Company’s financial position, results of operations and expected results of operations because the Non-GAAP Financial Measures facilitate a period to period comparison of operating results by excluding significant unusual, non-recurring items in 2026 and 2025. For 2026, these items relate to after-tax and pre-tax business realignment costs, after-tax and pre-tax share-based compensation accelerated vesting, after-tax and pre-tax Control Devices sale transaction bonuses, after-tax and pre-tax Brazilian indirect taxes and after-tax and pre-tax deferred financing fee write-off. For 2025, these items relate to pre-tax business realignment costs. These Non-GAAP Financial Measures, however, should not be considered in isolation or as a substitute for the most comparable GAAP financial measures. Investors are cautioned that non-GAAP financial measures used by the Company may not be comparable to non-GAAP financial measures used by other companies. Adjusted Gross Profit and Margin, Adjusted Operating Income (Loss) and Margin, Adjusted Income (Loss) Before Tax, Adjusted Tax Expense (Benefit), Adjusted Net Loss From Continuing Operations, Adjusted Net Income (Loss), Adjusted EPS, EBITDA, Adjusted EBITDA and Margin, and Net Debt should not be considered a substitute for Gross Profit, Operating Income (Loss), Income (Loss) Before Tax, Income Tax Expense (Benefit), Net Loss, Loss per Share, Debt or Cash and Cash Equivalents prepared in accordance with GAAP.

The exhibits attached hereto provide reconciliation details on normalizing adjustments of non-GAAP financial measures used in this press release.

“The first quarter represents solid progress to start the year and an important step forward in executing our long-term strategy,” said Natalia Noblet, president and chief executive officer. “Our results were driven by improved

manufacturing performance, reduced quality-related costs, favorable net tariff recoveries, and cost control across the organization. MirrorEye continues to be a key growth driver, delivering record first quarter sales and accelerating momentum with global OEMs in the commercial vehicle end markets. We remain focused on driving earnings expansion as we capitalize on our portfolio of advanced technologies and drive cost efficiencies to improve profitability.”

Noblet continued, “Our priority is to deliver outstanding value to customers while collaborating with our partners to advance next-generation technologies for safer and more efficient transportation. Today, we are announcing two major business awards totaling over $135 million of estimated lifetime revenue, including an OEM-integrated MirrorEye program with our fourth North American OEM customer, and a next-generation electronic controls program for a global off-highway manufacturer. These awards highlight our ability to deliver reliable, high-performance solutions for our customers while continuing to build on our strong backlog of growth products."

2026 Quarter in Review

Electronics first quarter sales of $144.9 million increased by $11.6 million, or 8.7%, relative to the fourth quarter of 2025. This was primarily driven by higher sales in the European and North American commercial vehicle end markets, including MirrorEye, incremental contract manufacturing revenue related to the sale of Control Devices, and higher off-highway sales. First quarter adjusted operating margin of 2.8% increased by 260 basis points compared to the fourth quarter of 2025, primarily driven by contribution on higher sales, lower direct material and overhead costs, including net tariff-related recoveries, partially offset by higher SG&A and D&D costs.

Relative to the first quarter of 2025, Electronics first quarter sales increased by $4.3 million, or 3.1%. This was primarily driven by favorable foreign translation impact of $12.9 million, higher MirrorEye sales, incremental contract manufacturing revenue, and higher sales in the North American commercial vehicle and European off-highway end markets. These increases were partially offset by lower sales in the European commercial vehicle end market, including lower sales for the Smart 2 tachograph due to the end of a regulatory retrofit campaign. First quarter adjusted operating margin of 2.8% decreased by 210 basis points compared to the first quarter of 2025, primarily driven by higher material costs due to sales mix and the impact of foreign currency, offset by lower D&D and quality-related costs.

Stoneridge Brazil first quarter sales of $18.1 million increased by $1.6 million, or 9.4%, relative to the fourth quarter of 2025, primarily driven by higher OEM sales in the Brazilian market and favorable foreign currency translation. First quarter adjusted operating income of $1.7 million, or 9.5% of sales, increased by $0.4 million, or 140 basis points, relative to the fourth quarter of 2025, primarily driven by fixed cost leverage on higher sales and lower SG&A costs, partially offset by unfavorable sales mix from a lower proportion of monitoring fees.

Relative to the first quarter of 2025, Stoneridge Brazil first quarter sales increased by $3.7 million, or 25.9%. This increase was primarily driven by higher OEM sales in the Brazilian market and the foreign currency translation impact of approximately $1.6 million. First quarter adjusted operating income of $1.7 million, or 9.5% of sales, increased $1.1 million, or 550 basis points, compared to the first quarter of 2025 primarily due to contribution from higher sales and lower material costs.

Cash and Debt Balances

As of March 31, 2026, Stoneridge had cash and cash equivalents totaling $70.5 million and total debt of $156.5 million resulting in net debt of $85.9 million. Net debt improved by $42.0 million compared to December 31, 2025 primarily from the use of proceeds from the sale of Control Devices to pay down debt.

Bob Hartman, interim chief financial officer, commented, “We remain focused on driving strong cash flow conversion through disciplined working capital management and capital expenditures. As part of this effort, we

reduced inventory balances by approximately $16 million compared to the first quarter of prior year. Recently, we also initiated a process to refinance our existing credit facility to better align our capital structure with the current Company structure. The refinancing will provide financial flexibility as well as support our future growth initiatives. We expect to complete this process by November of this year.”

2026 Outlook

The Company is updating its full-year revenue and operating guidance ranges to reflect the incremental impact of contract manufacturing revenue from the Mexico Supply Agreement related to the sale of Control Devices. This agreement was previously guided as non-operating other income, net and therefore only included in our adjusted EBITDA guidance. The Company is reaffirming its previously provided full-year EBITDA guidance.

Hartman commented, “We are first reaffirming our base full-year guidance, supported by the solid start to the year and continued execution across our business. While macroeconomic volatility and inflationary pressures persist, we remain confident in our initial outlook and the meaningful progress we are making across our key initiatives. We also remain focused on driving organizational efficiencies and have already taken decisive actions to reduce structural costs to better align our cost base with the Company’s current scale, positioning us to deliver sustainable long-term performance.”

Hartman continued, “We are also updating our guidance to reflect contract manufacturing revenue from the Mexico Supply Agreement. While the estimated benefit of this agreement was previously included in our adjusted EBITDA guidance as non-operating other income, net, we are updating our full-year revenue guidance by $20 million to reflect the estimated impact. We are also updating our overall adjusted operating margin guidance by approximately 50 basis points.”

As a result, the Company is updating its full-year revenue guidance to $645 million to $670 million and adjusted operating margin guidance to approximately break-even to 0.5%. The Company is reaffirming its adjusted gross margin guidance to 21.5% to 22.0% and adjusted EBITDA guidance of $20 million to $25 million.

Use of Non-GAAP Financial Information

This press release 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 press release. The provision of these non-GAAP financial measures for 2026 and 2025 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 press release and the adjustments that management can reasonably estimate.

In evaluating its business, the Company considers and uses free cash flow and net debt as supplemental measures of its liquidity and the other non-GAAP financial measures as supplemental measures of its operating performance. Management believes the non-GAAP financial measures used in this press release 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 income tax expense (benefit), adjusted net loss from continuing operations, adjusted net income (loss), adjusted EPS, EBITDA, adjusted EBITDA, and net debt 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 income tax expense (benefit), adjusted net income loss from continuing operations, adjusted net income (loss), adjusted EPS, EBITDA, adjusted EBITDA, and net debt should not be considered in isolation or as a substitute for gross profit, operating income (loss), income (loss) before tax, income tax expense (benefit), loss from continuing operations, net income (loss), EPS, 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 © 2026 Q1 2026 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 2026 and 2025 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, and net debt 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, and net debt 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.
