Our non-GAAP measures include: earnings before interest and taxes (EBIT)-adjusted, presented net of noncontrolling interests; earnings before income taxes (EBT)-adjusted for our General Motors Financial Company, Inc. (GM Financial) segment; earnings per share (EPS)-diluted-adjusted; effective tax rate-adjusted (ETR-adjusted); return on invested capital-adjusted (ROIC-adjusted); and adjusted automotive free cash flow. GM's calculation of these non-GAAP measures may not be comparable to similarly titled measures of other companies due to potential differences between companies in the method of calculation. As a result, the use of these non-GAAP measures has limitations and should not be considered superior to, in isolation from, or as a substitute for, related U.S. GAAP measures. These non-GAAP measures allow management and investors to view operating trends, perform analytical comparisons, and benchmark performance between periods and among geographic regions to understand operating performance without regard to items we do not consider a component of our core operating performance. Furthermore, these non-GAAP measures allow investors the opportunity to measure and monitor our performance against our externally communicated targets and evaluate the investment decisions being made by management to improve ROIC-adjusted. Management uses these measures in its financial, investment, and operational decision-making processes, for internal reporting, and as part of its forecasting and budgeting processes. Further, our Board of Directors uses certain of these and other measures as key metrics to determine management performance under our performance-based compensation plans. For these reasons, we believe these non-GAAP measures are useful for our investors. EBIT-adjusted (Most comparable GAAP measure: Net income attributable to stockholders) EBIT-adjusted is presented net of noncontrolling interests and is used by management and can be used by investors to review our consolidated operating results because it excludes automotive interest income, automotive interest expense, and income taxes as well as certain additional adjustments that are not considered part of our core operations. Examples of adjustments to EBIT include, but are not limited to, impairment charges on long-lived assets and other exit costs resulting from strategic shifts in our operations or discrete market and business conditions, and certain costs arising from legal matters. For EBIT-adjusted and our other non-GAAP measures, once we have made an adjustment in the current period for an item, we will also adjust the related non-GAAP measure in any future periods in which there is an impact from the item. Our corresponding measure for our GM Financial segment is EBT-adjusted because interest income and interest expense are an integral part of its financial performance. EPS-diluted-adjusted (Most comparable GAAP measure: Diluted earnings per common share) EPS-diluted-adjusted is used by management and can be used by investors to review our consolidated diluted EPS results on a consistent basis. EPS-diluted-adjusted is calculated as net income attributable to common stockholders-diluted less adjustments noted above for EBIT-adjusted and certain income tax adjustments divided by weighted-average common shares outstanding-diluted. Examples of income tax adjustments include the establishment or release of significant deferred tax asset valuation allowances. ETR-adjusted (Most comparable GAAP measure: Effective tax rate) ETR-adjusted is used by management and can be used by investors to review the consolidated effective tax rate for our core operations on a consistent basis. ETR-adjusted is calculated as Income tax expense less the income tax related to the adjustments noted above for EBIT-adjusted and the income tax adjustments noted above for EPS-diluted-adjusted divided by Income before income taxes less adjustments. When we provide an expected adjusted effective tax rate, we cannot provide an expected effective tax rate without unreasonable efforts because the U.S. GAAP measure may include significant adjustments that are difficult to predict. ROIC-adjusted (Most comparable GAAP measure: Return on equity) ROIC-adjusted is used by management and can be used by investors to review our investment and capital allocation decisions. We define ROIC-adjusted as EBIT-adjusted for the trailing four quarters divided by ROIC-adjusted average net assets, which is the average equity balances adjusted for average automotive debt and interest liabilities, exclusive of finance leases; average automotive net pension and other postretirement benefits (OPEB) liabilities; and average automotive net income tax assets during the same period. Adjusted automotive free cash flow (Most comparable GAAP measure: Net automotive cash provided by operating activities) Adjusted automotive free cash flow is used by management and can be used by investors to review the liquidity of our automotive operations and to measure and monitor our performance against our capital allocation program and evaluate our automotive liquidity against the substantial cash requirements of our automotive operations. We measure adjusted automotive free cash flow starting with automotive operating cash flow from operations. We subtract capital expenditures, add the imputed cash effects of third-party payments made on our behalf for inventory banking, and subtract the cash effects when the banked inventory is consumed. The result is then adjusted for management actions, which can include voluntary events such as discretionary contributions to employee benefit plans or nonrecurring specific events such as a closure of a facility that are considered special for EBIT-adjusted purposes. 10 General Motors Company and Subsidiaries Supplemental Material 1 (Unaudited) The following table reconciles Net income (loss) attributable to stockholders to EBIT-adjusted and segment profit (loss) (dollars in millions): Three Months Ended Nine Months Ended September 30, 2026 September 30, 2025 September 30, 2026 September 30, 2025 Net income (loss) attributable to stockholders $ 3,335 $ 1,327 $ 7,267 $ 6,007 Income tax expense (benefit) 565 127 1,422 1,326 Automotive interest expense 162 209 472 560 Automotive interest income (195) (220) (551) (611) Adjustments EV strategic realignment(a) 238 1,592 3,594 1,922 China restructuring actions(b) — — 99 140 Legal matters(c) — 300 — 300 Restructuring and other strategic actions(d) — 41 — 260 Total adjustments 238 1,933 3,693 2,622 EBIT-adjusted 4,106 3,376 12,302 9,903 Operating segments GM North America (GMNA) 3,592 2,506 10,699 8,207 GM International (GMI) 28 226 342 460 Cruise — — — (273) GM Financial(e) 668 804 1,962 2,193 Total operating segments 4,289 3,536 13,003 10,587 Corporate and eliminations(f) (183) (160) (700) (684) EBIT-adjusted $ 4,106 $ 3,376 $ 12,302 $ 9,903 __________ (a) These adjustments were excluded because they relate to our strategic realignment of our EV capacity and manufacturing footprint, including Ultium's strategic realignment.

Wholesale vehicle sales data consists of sales to GM's dealers and distributors as well as sales to the U.S. Government, and excludes vehicles sold by our joint ventures. Wholesale vehicle sales data correlates to GM's revenue recognized from the sale of vehicles, which is the largest component of Automotive net sales and revenue. In the nine months ended September 30, 2026, 27.6% of GM's wholesale vehicle sales volume was generated outside the U.S. The following table summarizes wholesale vehicle sales by our Automotive operations (vehicles in thousands): Three Months Ended Nine Months Ended September 30, 2026 September 30, 2025 September 30, 2026 September 30, 2025 GMNA 870 840 2,511 2,516 GMI 159 137 407 346 Total 1,028 977 2,917 2,862 Total vehicle sales data represents: (1) retail sales (i.e., sales to consumers who purchase new vehicles from dealers or distributors); (2) fleet sales (i.e., sales to large and small businesses, governments, and daily rental car companies); and (3) certain vehicles used by dealers in their business, including but not limited to courtesy transportation vehicles previously used by dealers that were sold to the end consumer. Total vehicle sales data includes all sales by joint ventures on a total vehicle basis, not based on our percentage ownership interest in the joint venture, including vehicle sales of non-GM trademarked vehicles, which are included in the total vehicle sales we report for China. While total vehicle sales data does not correlate directly to the revenue GM recognizes during a particular period, we believe it is indicative of the underlying demand for GM's vehicles. Total vehicle sales data represents management's good faith estimate based on sales reported by our dealers, distributors, and joint ventures; commercially available data sources, such as registration and insurance data; and internal estimates and forecasts when other data is not available. 14 General Motors Company and Subsidiaries Supplemental Material 1 (Unaudited) The following table summarizes industry and GM total vehicle sales and GM's related competitive position by geographic region (vehicles in thousands): Three Months Ended Nine Months Ended September 30, 2026 September 30, 2025 September 30, 2026 September 30, 2025 Industry GM Market Share Industry GM Market Share Industry GM Market Share Industry GM Market Share North America United States 4,174 671 16.1 % 4,229 710 16.8 % 12,277 2,012 16.4 % 12,567 2,150 17.1 % Other 1,045 126 12.1 % 1,015 127 12.5 % 3,032 376 12.4 % 3,007 384 12.8 % Total North America 5,219 797 15.3 % 5,244 837 16.0 % 15,309 2,388 15.6 % 15,574 2,534 16.3 % Asia/Pacific, Middle East, and Africa China(a) 5,403 358 6.6 % 6,934 469 6.8 % 15,816 1,065 6.7 % 19,333 1,359 7.0 % Other 5,778 115 2.0 % 5,718 149 2.6 % 17,501 329 1.9 % 17,010 369 2.2 % Total Asia/Pacific, Middle East, and Africa 11,181 474 4.2 % 12,652 618 4.9 % 33,317 1,394 4.2 % 36,342 1,729 4.8 % South America Brazil 836 84 10.1 % 711 72 10.1 % 2,255 225 10.0 % 1,910 192 10.1 % Other 485 35 7.1 % 456 35 7.7 % 1,408 103 7.3 % 1,268 95 7.5 % Total South America 1,321 119 9.0 % 1,168 107 9.2 % 3,663 328 9.0 % 3,177 287 9.0 % Total in GM markets 17,721 1,390 7.8 % 19,064 1,562 8.2 % 52,288 4,111 7.9 % 55,093 4,549 8.3 % Total Europe 4,007 1 — % 4,002 1 — % 13,020 1 — % 12,611 2 — % Total Worldwide(b) 21,729 1,390 6.4 % 23,066 1,563 6.8 % 65,309 4,112 6.3 % 67,704 4,551 6.7 % United States Cars 667 12 1.7 % 649 12 1.8 % 1,991 36 1.8 % 2,076 44 2.1 % Trucks 1,159 359 31.0 % 1,142 369 32.3 % 3,343 1,061 31.7 % 3,414 1,115 32.6 % Crossovers 2,348 300 12.8 % 2,437 330 13.5 % 6,943 915 13.2 % 7,076 992 14.0 % Total United States 4,174 671 16.1 % 4,229 710 16.8 % 12,277 2,012 16.4 % 12,567 2,150 17.1 % China(a) SGMS 90 130 300 381 SGMW 269 339 765 978 Total 5,403 358 6.6 % 6,934 469 6.8 % 15,816 1,065 6.7 % 19,333 1,359 7.0 % __________ (a) Includes sales by the Automotive China JVs: SAIC General Motors Sales Co., Ltd.
