Accounting Policies [Abstract]
Recently Issued Accounting Standards	Recently Issued Accounting Standards Accounting Standards Not Yet Adopted In November 2023, the FASB issued ASU No. 2023-07, "Segment Reporting (Topic 280) – Improvements to Reportable Segment Disclosures", which expands annual and interim disclosure requirements for reportable segments, primarily through enhanced disclosures about significant segment expenses. The updated standard is effective for annual periods beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. We are currently evaluating the impact that the updated standard will have on our financial statement disclosures. In December 2023, the FASB issued ASU No. 2023-09, “Income Taxes (Topic 740) – Improvements to Income Tax Disclosures," which requires companies to disclose, on an annual basis, specific categories in the effective tax rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold. In addition, companies are required to disclose additional information about income taxes paid. The standard is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The standard is to be adopted on a prospective basis; however, retrospective application is permitted. We are currently evaluating the impact on our annual consolidated financial statement disclosures.

Revenue

Revenue from Contract with Customer [Abstract]
Revenue	Revenue Revenue is recognized when obligations under the terms of a contract with our customer are satisfied; generally this occurs with the transfer of control of our products and services, which is usually when the parts are shipped or delivered to the customer’s premises. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods or providing services. The transaction price will include estimates of variable consideration to the extent it is probable that a significant reversal of revenue recognized will not occur. Incidental items that are not significant in the context of the contract are recognized as expense. The expected costs associated with our base warranties continue to be recognized as expense when the products are sold. Customer returns only occur if products do not meet the specifications of the contract and are not connected to any repurchase obligations of the Company. The Company does not have any financing components or significant payment terms as payment occurs shortly after the point of sale. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction that are collected by the Company from a customer are excluded from revenue. Amounts billed to customers related to shipping and handling costs are included in net sales in the condensed consolidated statements of operations. Shipping and handling costs associated with outbound freight after control over a product is transferred to the customer are accounted for as a fulfillment cost and are included in cost of sales. Revenue by Reportable Segment Control Devices. Our Control Devices segment designs and manufactures products that monitor, measure or activate specific functions within a vehicle. This segment includes product lines such as actuators, sensors, switches and connectors. We sell these products principally to the automotive market in the North American and Asia Pacific regions. To a lesser extent, we also sell these products to the commercial vehicle and agricultural markets in the North American and Asia Pacific regions. Our customers included in these markets primarily consist of original equipment manufacturers (“OEM”) and companies supplying components directly to the OEMs (“Tier 1 supplier”). Electronics. Our Electronics segment designs and manufactures driver information systems, vision and safety systems, connectivity and compliance products and electronic control units. These products are sold principally to the commercial vehicle market primarily through our OEM and aftermarket channels in the European, North American and Asia Pacific regions. Our vision and safety systems are sold principally to the commercial vehicle and off-highway vehicle markets in the European and North American regions. Stoneridge Brazil.

Performance Obligations For OEM and Tier 1 supplier customers, the Company typically enters into contracts to provide serial production parts that consist of a set of documents including, but not limited to, an award letter, master purchase agreement and master terms and conditions. For each production product, the Company enters into separate purchase orders that contain the product specifications and an agreed-upon price. The performance obligation does not exist until a customer release is received for a specific number of parts. The majority of the parts sold to OEM and Tier 1 supplier customers are customized to the specific customer, with the exception of camera monitoring systems (“CMS”) sold through our aftermarket channel that are common across all customers. The transaction price is equal to the contracted price per part and there is no expectation of material variable consideration in the transaction price. For most customer contracts, the Company does not have an enforceable right to payment at any time prior to when the parts are shipped or delivered to the customer; therefore, the Company recognizes revenue at the point in time it satisfies a performance obligation by transferring control of a part to the customer. Certain customer contracts contain an enforceable right to payment if the customer terminates the contract for convenience and therefore are recognized over time using the cost to complete input method. Our aftermarket products are focused on meeting the demand for safety, compliance and entertainment applications. Including products, accessories and replacement parts and are sold primarily to aftermarket distributors in our South American and European markets, as well as direct to aftermarket customers in North America. Aftermarket products have one type of performance obligation, which is the delivery of aftermarket parts and spare parts. For aftermarket customers, the Company typically has standard terms and conditions for all customers. In addition, aftermarket products have alternative use as they can be sold to multiple customers. Revenue for aftermarket part production contracts is recognized at a point in time when the control of the parts transfers to the customer, which is based on the shipping terms. Aftermarket contracts may include variable consideration related to discounts and rebates, which is included in the transaction price upon recognizing the product revenue. A small portion of the Company’s sales are comprised of monitoring services that include both monitoring devices and fees to individual, corporate, fleet and cargo customers in our Stoneridge Brazil segment. These monitoring service contracts are generally not capable of being distinct and are accounted for as a single performance obligation. We recognize revenue for our monitoring products and services contracts over the life of the contract. There is no variable consideration associated with these contracts. The Company has the right to consideration from a customer in the amount that corresponds directly with the value to the customer of the Company’s performance to date. Therefore, the Company recognizes revenue over time using the practical expedient ASC 606-10-55-18 in the amount the Company has a “right to invoice” rather than selecting an output or input method. Contract Balances The Company had no material contract assets, contract liabilities or capitalized contract acquisition costs as of September 30, 2024 and December 31, 2023.

Inventory Disclosure [Abstract]
Inventories	Inventories Inventories are valued at the lower of cost (using either the first-in, first-out (“FIFO”) or average cost methods) or net realizable value. The Company evaluates and adjusts as necessary its excess and obsolescence reserve on a quarterly basis. Excess inventories are quantities of items that exceed anticipated sales or usage for a reasonable period. The Company has guidelines for calculating provisions for excess inventories based on the number of months of inventories on hand compared to anticipated sales or usage. Management uses its judgment to forecast sales or usage and to determine what constitutes a reasonable period. Inventory cost includes material, labor and overhead. Inventories consist of the following: September 30, December 31, Raw materials $ 128,437 $ 142,744 Work-in-progress 8,071 11,907 Finished goods 39,937 33,107 Total inventories, net $ 176,445 $ 187,758 Inventory valued using the FIFO method was $162,151 and $176,033 at September 30, 2024 and December 31, 2023, respectively.

Fair Value Disclosures [Abstract]
Financial Instruments and Fair Value Measurements	Financial Instruments and Fair Value Measurements Financial Instruments A financial instrument is cash or a contract that imposes an obligation to deliver or conveys a right to receive cash or another financial instrument. The carrying values of cash and cash equivalents, accounts receivable and accounts payable are considered to be representative of fair value because of the short maturity of these instruments. The fair value of debt approximates the carrying value of debt, due to the variable interest rate on our Credit Facility and the maturity of the remaining outstanding debt. Derivative Instruments and Hedging Activities On September 30, 2024, the Company had open Mexican peso-denominated foreign currency forward contracts. The Company used foreign currency forward contracts solely for hedging and not for speculative purposes during 2024 and 2023. Management believes that its use of these instruments to reduce risk is in the Company’s best interest. The counterparties to these financial instruments are financial institutions with investment grade credit ratings. Foreign Currency Exchange Rate Risk Foreign currency transactions are remeasured into the functional currency using translation rates in effect at the time of the transaction with the resulting adjustments included on the condensed consolidated statements of operations within other (income) expense, net. These foreign currency transaction (gains) losses, including the impact of hedging activities, were $(320) and $(1,359) for the three months ended September 30, 2024 and 2023, respectively, and $(646) and $2,099 for the nine months ended September 30, 2024 and 2023, respectively. The Company conducts business internationally and, therefore, is exposed to foreign currency exchange rate risk. The Company uses derivative financial instruments as cash flow hedges to manage its exposure to fluctuations in foreign currency exchange rates by reducing the effect of such fluctuations on foreign currency denominated intercompany transactions, inventory purchases and other foreign currency exposures. Cash Flow Hedges The Company entered into foreign currency forward contracts to hedge the Mexican peso currency in 2024 and 2023. These forward contracts were executed to hedge forecasted transactions and have been accounted for as cash flow hedges. As such, gains and losses on derivatives qualifying as cash flow hedges are recorded in accumulated other comprehensive loss, to the extent that hedges are effective, until the underlying transactions are recognized in earnings. Unrealized amounts in accumulated other comprehensive loss fluctuate based on changes in the fair value of hedge derivative contracts at each reporting period. The cash flow hedges were highly effective. The effectiveness of the transactions was measured using regression analysis and forecasted future purchases of the currency. In certain instances, the foreign currency forward contracts may not qualify for hedge accounting or are not designated as hedges and, therefore, are marked-to-market with gains and losses recognized in the Company’s condensed consolidated statements of operations as a component of other (income) expense, net. At September 30, 2024, all of the Company’s foreign currency forward contracts were designated as cash flow hedges. The Company’s foreign currency forward contracts offset a portion of the gains and losses on the underlying foreign currency denominated transactions as follows: Mexican peso-denominated Foreign Currency Forward Contracts – Cash Flow Hedges The Company holds Mexican peso-denominated foreign currency forward contracts with a notional amount at September 30, 2024 of $31,183, which expire ratably on a monthly basis from October 2024 to December 2025 . The notional amounts at December 31, 2023 related to Mexican peso-denominated foreign currency forward contracts were $26,613. The Company evaluated the effectiveness of the Mexican peso denominated forward contracts held as of September 30, 2024 and concluded that the hedges were highly effective. Interest Rate Risk Interest Rate Risk – Cash Flow Hedge On February 18, 2020, the Company entered into a floating-to-fixed interest rate swap agreement (the “Swap”) with a notional amount of $50,000 to hedge its exposure to interest payment fluctuations on a portion of its Credit Facility borrowings. The Swap matured on March 10, 2023. The Swap was designated as a cash flow hedge of the variable interest rate obligation under the Company's Fourth Amended and Restated Credit Agreement, as amended, (the “Fourth Amended and Restated Credit Agreement”). Accordingly, the change in fair value of the Swap was recognized in accumulated other comprehensive loss. The Swap agreement required monthly settlements on the same days that the Fourth Amended and Restated Credit Agreement interest payments were due. The Swap's maturity date of March 10, 2023, was before the Fourth Amended and Restated Credit Agreement maturity date of June 5, 2024. Under the Swap terms, the Company paid a fixed interest rate and received a floating interest rate based on the one-month LIBOR, with a floor. The critical terms of the Swap were aligned with the terms of the Fourth Amended and Restated Credit Agreement , resulting in no hedge ineffectiveness. The difference between amounts to be received and paid under the Swap were recognized as a component of interest expense, net on the condensed consolidated statements of operations. The Swap settlements reduced interest expense, net by $290 for the nine months ended September 30, 2023. The notional amounts and fair values of derivative instruments in the condensed consolidated balance sheets were as follows: Notional amounts (A) Prepaid expenses Accrued expenses and September 30, December 31, September 30, December 31, September 30, December 31, Derivatives designated as hedging instruments: Cash flow hedges: Forward currency contracts $ 31,183 $ 26,613 $ — $ 1,858 $ 2,032 $ — _____________________________ (A) Notional amounts represent the gross contract of the derivatives outstanding in U.S. dollars.

(Losses) gains reclassified from other comprehensive income (loss) into net (loss) income recognized in cost of goods sold (“COGS”) in the Company’s condensed consolidated statements of operations were $(293) and $173 for the three months ended September 30, 2024 and 2023, respectively. Gross amounts recorded for the cash flow and net investment hedges in other comprehensive (loss) income and in net loss for the nine months ended September 30 were as follows: (Loss) gain recorded in other Gain reclassified from other comprehensive (loss) income into net loss (A) 2024 2023 2024 2023 Derivatives designated as cash flow hedges: Forward currency contracts $ (3,257) $ 483 $ 633 $ 278 Interest rate swap $ — $ (4) $ — $ 290 (A) Gains reclassified from other comprehensive (loss) income into net loss recognized in SG&A in the Company’s condensed consolidated statements of operations were $109 and $66 for the nine months ended September 30, 2024 and 2023, respectively. Gains reclassified from other comprehensive (loss) income into net loss recognized in COGS in the Company’s condensed consolidated statements of operations were $524 and $212 for the nine months ended September 30, 2024 and 2023, respectively. Gains reclassified from other comprehensive (loss) income into net loss recognized in interest expense, net in the Company’s condensed consolidated statements of operations were $0 and $290 for the nine months ended September 30, 2024 and 2023, respectively. Cash flows from derivatives used to manage foreign currency exchange and interest rate risks are classified as operating activities within the condensed consolidated statements of cash flows. Fair Value Measurements Certain assets and liabilities held by the Company are measured at fair value on a recurring basis and are categorized using the three levels of the fair value hierarchy based on the reliability of the inputs used. Fair values estimated using Level 1 inputs consist of quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date. Fair values estimated using Level 2 inputs, other than quoted prices, are observable for the asset or liability, either directly or indirectly and include among other things, quoted prices for similar assets or liabilities in markets that are active or inactive as well as inputs other than quoted prices that are observable. For forward currency and cross-currency contracts, inputs include forward foreign currency exchange rates. For the interest rate swap, inputs included LIBOR. Fair values estimated using Level 3 inputs consist of significant unobservable inputs. The following table presents our assets and liabilities that are measured at fair value on a recurring basis and are categorized using the three levels of the fair value hierarchy based on the reliability of inputs used.

(Loss) Earnings Per Share

(Loss) Earnings Per Share	9 Months Ended
	Sep. 30, 2024
Earnings Per Share [Abstract]
(Loss) Earnings Per Share	(Loss) Earnings Per Share Basic (loss) earnings per share was computed by dividing net (loss) income by the weighted-average number of Common Shares outstanding for each respective period. Diluted (loss) earnings per share was calculated by dividing net income by the weighted-average of all potentially dilutive Common Shares that were outstanding during the periods presented. However, for all periods in which the Company recognized a net loss, the Company did not recognize the effect of the potential dilutive securities as their inclusion would be anti-dilutive. Potential dilutive shares of 237,870 for the three months ended September 30, 2024 were excluded from diluted loss per share because the effect would be anti-dilutive. Potential dilutive shares of 244,471 and 238,342 for the nine months ended September 30, 2024 and 2023, respectively, were excluded from diluted loss per share because the effect would be anti-dilutive. Weighted-average Common Shares outstanding used in calculating basic and diluted earnings per share were as follows: Three months ended Nine months ended 2024 2023 2024 2023 Basic weighted-average Common Shares outstanding 27,617,663 27,483,709 27,585,904 27,428,249 Effect of dilutive shares — 250,400 — — Diluted weighted-average Common Shares outstanding 27,617,663 27,734,109 27,585,904 27,428,249 There were 612,886 and 425,612 performance-based right to receive Common Shares outstanding at September 30, 2024 and 2023, respectively. The right to receive Common Shares are included in the computation of diluted earnings per share, to the extent they are not anti-dilutive, based on the number of Common Shares that would be issuable if the end of the quarter were the end of the performance period.

Commitments and Contingencies

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies From time to time, we are subject to various legal actions and claims incidental to our business, including those arising out of breach of contracts, product warranties, product liability, patent infringement, regulatory matters and employment-related matters. The Company establishes accruals for matters which it believes that losses are probable and can be reasonably estimated. Although it is not possible to predict with certainty the outcome of these matters, the Company is of the opinion that the ultimate resolution of these matters will not have a material adverse effect on its consolidated results of operations or financial position. As a result of environmental studies performed at the Company’s former facility located in Sarasota, Florida, the Company became aware of soil and groundwater contamination at the site. The Company engaged an environmental engineering consultant to assess the level of contamination and to develop a remediation and monitoring plan for the site. Soil remediation at the site was completed during the year ended December 31, 2010. A remedial action plan was approved by the Florida Department of Environmental Protection and groundwater remediation began in the fourth quarter of 2015. During the three months ended September 30, 2024 and 2023, the Company recognized expense of $157 and $0, respectively, related to groundwater remediation. During the nine months ended September 30, 2024 and 2023, the Company recognized expense of $157 and $125, respectively, related to groundwater remediation. At September 30, 2024 and December 31, 2023, the Company accrued $265 and $143, respectively, related to expected future remediation costs. At September 30, 2024 and December 31, 2023, $165 and $136, respectively, were recorded as a component of accrued expenses and other current liabilities in the condensed consolidated balance sheets while the remaining amounts as of September 30, 2024 and December 31, 2023 were recorded as a component of other long-term liabilities. Costs associated with the recorded liability will be incurred to complete the groundwater remediation and monitoring. The recorded liability is based on assumptions in the remedial action plan as well as estimates for future remediation activities. Although the Company sold the Sarasota facility and related property in December 2011, the liability to remediate the site contamination remains the responsibility of the Company. Due to the ongoing site remediation, the Company is currently required to maintain a $1,489 letter of credit for the benefit of the buyer. The Company’s Stoneridge Brazil subsidiary has civil, labor and other tax contingencies (excluding income tax) for which the likelihood of loss is deemed to be reasonably possible, but not probable, by the Company’s legal advisors in Brazil. As a result, no provision has been recorded with respect to these contingencies, which amounted to R$43,848 ($8,049) and R$41,681 ($8,609) at September 30, 2024 and December 31, 2023, respectively. An unfavorable outcome on these contingencies could result in significant cost to the Company and adversely affect its results of operations and cash flows. On August 12, 2020, the Brazilian Administrative Counsel for Economic Defense (“CADE”) issued a ruling against Stoneridge Brazil for abuse of dominance and market foreclosure through its prior use of exclusivity provisions in agreements with its distributors. The CADE tribunal imposed a R$7,995 ($1,468) fine which is included in the reasonably possible contingencies noted above. The Company continues to challenge this ruling in Brazilian federal court to reverse this decision by the CADE tribunal. Long Term Supply Commitment In 2022, the Company entered into a long term supply agreement, as amended, with a supplier for the purchase of certain electronic semiconductor components through December 31, 2027. Pursuant to the agreement, the Company paid capacity deposits of $1,000 each in December 2022 and June 2023. The capacity deposits are recognized in prepaid and other current assets on our condensed consolidated balance sheets and amortized ratably over the life of the purchase commitment. This long term supply agreement requires the Company to purchase minimum annual volumes while requiring the supplier to sell these components at a fixed price. The Company purchased $1,840 and $1,252 of these components during the three months ended September 30, 2024 and 2023, respectively, and $2,662 and $4,579 during the nine months ended September 30, 2024 and 2023, respectively. The Company is required to purchase $3,914, $10,764, $10,764 and $3,914 of these components in each of the years 2024 through 2027, respectively. Product Warranty and Recall Amounts accrued for product warranty and recall claims are established based on the Company’s best estimate of the amounts necessary to settle existing and future claims on products sold as of the balance sheet dates. These accruals are based on several factors including past experience, production changes, industry developments and various other considerations. Our estimate is based on historical trends of units sold and claim payment amounts, combined with our current understanding of the status of existing claims, forecasts of the resolution of existing claims, expected future claims on products sold and commercial discussions with our customers. The key factors in our estimate are the warranty period and the customer source. The Company can provide no assurances that it will not experience material claims or that it will not incur significant costs to defend or settle such claims beyond the amounts accrued. The current portion of the product warranty and recall reserve is included as a component of accrued expenses and other current liabilities on the condensed consolidated balance sheets. Product warranty and recall reserve included $9,154 and $7,228 of a long-term liability at September 30, 2024 and December 31, 2023, respectively, which is included as a component of other long-term liabilities on the condensed consolidated balance sheets. During the second quarter of 2023, the Company received a demand for arbitration from one of our customers seeking recovery for warranty claims related to past sales of PM sensor products, a product line we exited in 2019. In March 2024, pursuant to the arbitration process, the customer submitted a formal statement of claim notification for 29,340 euro ($32,669). In May 2024, the Company responded with a formal statement of defense denying responsibility for the claim. Based on our review of the technical merits and specific claims as well as prior discussions with the customer, we believe these warranty claims lack merit and are significantly overstated. While no assurances can be made as to the ultimate outcome of this matter, or any other future claims, we do not currently believe a material loss is probable. The following provides a reconciliation of changes in product warranty and recall reserve liability: Nine months ended September 30, 2024 2023 Product warranty and recall reserve at beginning of period $ 21,610 $ 13,477 Accruals for warranties established during period 13,789 10,521 Aggregate changes in pre-existing liabilities due to claim developments 416 579 Settlements made during the period (10,240) (5,519) Foreign currency translation (1) (386) Product warranty and recall reserve at end of period $ 25,574 $ 18,672

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For interim tax reporting, we estimate our annual effective tax rate and apply it to our year to date ordinary income. Tax jurisdictions with a projected or year to date loss for which a benefit cannot be realized are excluded. For the three months ended September 30, 2024, income tax expense of $3,413 was attributable to the mix of earnings among tax jurisdictions and tax losses for which no benefit is recognized due to valuation allowances in certain jurisdictions, offset by U.S. taxes on foreign earnings. The effective tax rate of (93.3)% varies from the statutory rate primarily due to the impact of tax losses for which no benefit is recognized due to valuation allowances in certain jurisdictions, offset by U.S. taxes on foreign earnings. For the three months ended September 30, 2023, income tax expense of $2,270 was attributable to the mix of earnings among tax jurisdictions as well as tax losses for which no benefit is recognized due to valuation allowances in certain jurisdictions. The effective tax rate of 51.1% varies from the statutory rate primarily due to U.S. taxes on foreign earnings and non-deductible expenses offset by the impact of tax losses for which no benefit is recognized due to valuation allowances in certain jurisdictions and tax credits and incentives. For the nine months ended September 30, 2024, income tax expense of $2,987 was attributable to the mix of earnings among tax jurisdictions and tax losses for which no benefit is recognized due to valuation allowances in certain jurisdictions, offset by U.S. taxes on foreign earnings. The effective tax rate of (40.2)% varies from the statutory rate primarily due to the impact of tax losses for which no benefit is recognized due to valuation allowances in certain jurisdictions, offset by U.S. taxes on foreign earnings. For the nine months ended September 30, 2023, income tax expense of $3,049 was attributable to the mix of earnings among tax jurisdictions as well as tax losses for which no benefit is recognized due to valuation allowances in certain jurisdictions. The effective tax rate of (59.1)% varies from the statutory rate primarily due to U.S. taxes on foreign earnings and non-deductible expenses offset by the impact of tax losses for which no benefit is recognized due to valuation allowances in certain jurisdictions and tax credits and incentives. The OECD (Organisation for Economic Co-operation and Development) implemented a 15% global corporate minimum tax ("Pillar Two") to ensure that large multinational enterprises pay a minimum level of tax in the countries they operate. During 2023, many countries took steps to incorporate Pillar Two into their domestic laws. In 2024, we do not expect a material change to our income tax provision in connection with Pillar Two. As additional jurisdictions implement this legislation, our effective tax rate and cash tax payments could increase in future years.

Segment Reporting [Abstract]
Segment Reporting	Segment Reporting Operating segments are defined as components of an enterprise that are evaluated regularly by the Company’s chief operating decision maker in deciding how to allocate resources and in assessing performance. The Company’s chief operating decision maker is the Chief Executive Officer. The Company has three reportable segments, Control Devices, Electronics and Stoneridge Brazil, which also represent its operating segments. The Control Devices reportable segment produces actuators, sensors, switches and connectors. The Electronics reportable segment produces driver information systems, vision and safety systems, connectivity and compliance products and electronic control units. The Stoneridge Brazil reportable segment designs and manufactures vehicle tracking devices and monitoring services, vehicle security alarms and convenience accessories, in-vehicle audio and infotainment devices, driver information systems and telematics solutions. The accounting policies of the Company’s reportable segments are the same as those described in Note 2, “Summary of Significant Accounting Policies” of the Company’s 2023 Form 10-K . The Company’s management evaluates the performance of its reportable segments based primarily on revenues from external customers, capital expenditures and operating income. Inter-segment sales are accounted for on terms similar to those to third parties and are eliminated upon consolidation. The financial information presented below is for our three reportable operating segments and includes adjustments for unallocated corporate costs and intercompany eliminations, where applicable. Such costs and eliminations do not meet the requirements for being classified as an operating segment. Corporate costs include various support functions, such as accounting/finance, executive administration, human resources, information technology and legal. A summary of financial information by reportable segment is as follows: Three months ended Nine months ended 2024 2023 2024 2023 Net Sales: Control Devices $ 73,129 $ 89,344 $ 230,186 $ 267,406 Inter-segment sales 1,160 733 2,946 2,437 Control Devices net sales 74,289 90,077 233,132 269,843 Electronics 127,483 134,652 422,777 435,565 Inter-segment sales 8,184 8,649 22,492 25,656 Electronics net sales 135,667 143,301 445,269 461,221 Stoneridge Brazil 13,219 14,168 37,084 43,332 Inter-segment sales 411 — 610 — Stoneridge Brazil net sales 13,630 14,168 37,694 43,332 Eliminations (9,755) (9,382) (26,048) (28,093) Total net sales $ 213,831 $ 238,164 $ 690,047 $ 746,303 Operating Income (Loss): Control Devices $ 2,131 $ 5,488 $ 8,020 $ 12,649 Electronics 3,514 7,647 20,434 16,491 Stoneridge Brazil 717 1,241 880 3,483 Unallocated Corporate (A) (6,047) (7,864) (25,281) (25,809) Total operating income $ 315 $ 6,512 $ 4,053 $ 6,814 Depreciation and Amortization: Control Devices $ 3,152 $ 3,100 $ 8,821 $ 9,373 Electronics 4,030 3,521 11,794 10,488 Stoneridge Brazil 1,155 1,259 3,652 3,545 Unallocated Corporate 492 593 1,696 1,800 Total depreciation and amortization (B) $ 8,829 $ 8,473 $ 25,963 $ 25,206 Interest Expense (Income), net: Control Devices $ 9 $ 37 $ (10) $ 120 Electronics 283 456 1,387 1,452 Stoneridge Brazil (204) (680) (798) (1,269) Unallocated Corporate 3,516 3,500 10,460 8,876 Total interest expense, net $ 3,604 $ 3,313 $ 11,039 $ 9,179 Capital Expenditures: Control Devices $ 2,914 $ 2,986 $ 6,018 $ 6,961 Electronics 1,298 4,710 5,652 13,251 Stoneridge Brazil 484 889 2,223 2,307 Unallocated Corporate (C) 212 371 972 700 Total capital expenditures $ 4,908 $ 8,956 $ 14,865 $ 23,219 September 30, December 31, Total Assets: Control Devices $ 153,043 $ 159,612 Electronics 399,467 404,994 Stoneridge Brazil 57,789 66,318 Corporate (C) 453,201 419,469 Eliminations (400,977) (370,493) Total assets $ 662,523 $ 679,900 The following tables present net sales and long-term assets for each of the geographic areas in which the Company operates: Three months ended Nine Months Ended 2024 2023 2024 2023 Net Sales: North America $ 109,395 $ 126,499 $ 349,025 $ 385,813 South America 13,219 14,168 37,084 43,332 Europe and Other 91,217 97,497 303,938 317,158 Total net sales $ 213,831 $ 238,164 $ 690,047 $ 746,303 September 30, December 31, Long-term Assets: North America $ 95,612 $ 92,419 South America 29,028 32,679 Europe and Other 123,470 125,412 Total long-term assets $ 248,110 $ 250,510 __________________________________________________________ (A) Unallocated Corporate expenses include, among other items, accounting/finance, human resources, information technology and legal costs as well as share-based compensation.

(the “Company”) without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). The information furnished in the condensed consolidated financial statements includes normal recurring adjustments and reflects all adjustments, which are, in the opinion of management, necessary for a fair presentation of such financial statements. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) have been condensed or omitted pursuant to the SEC’s rules and regulations. The results of operations for the three months ended September 30, 2024 are not necessarily indicative of the results to be expected for the full year. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto included in the Company’s 2023 Form 10-K .
Reclassifications	Reclassifications Certain prior period amounts have been reclassified to conform to their 2024 presentation in the condensed consolidated financial statements.
Accounting Standards Not Yet Adopted	Accounting Standards Not Yet Adopted In November 2023, the FASB issued ASU No. 2023-07, "Segment Reporting (Topic 280) – Improvements to Reportable Segment Disclosures", which expands annual and interim disclosure requirements for reportable segments, primarily through enhanced disclosures about significant segment expenses. The updated standard is effective for annual periods beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. We are currently evaluating the impact that the updated standard will have on our financial statement disclosures. In December 2023, the FASB issued ASU No. 2023-09, “Income Taxes (Topic 740) – Improvements to Income Tax Disclosures," which requires companies to disclose, on an annual basis, specific categories in the effective tax rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold.
