• 35. NON-GAAP FINANCIAL MEASURES Stellantis monitors its operations through the use of several non-generally accepted accounting principles (non-GAAP) financial measures. Company management believes that these non-GAAP financial measures provide useful and relevant information regarding our operating results and enhance the overall ability to assess our financial performance and financial position. These measures provide comparable measures which facilitate management’s ability to identify operational trends, as well as make decisions regarding future spending, resource allocations and other operational decisions. The non-GAAP measure, Adjusted diluted EPS is also presented, which is not used to monitor our operations but which we believe provides investors with a more meaningful comparison of the Company’s ongoing quality of earnings. These and similar measures are widely used in the industry in which the Company operates, however, these financial measures may not be comparable to other similarly titled measures of other companies and are not intended to be substitutes for measures of financial performance as prepared in accordance with International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board (IASB), as well as IFRS as adopted by the European Union. Stellantis’ non-GAAP financial measures are defined as follows: • Adjusted Operating Income/(Loss) excludes from Net profit/(loss) adjustments comprising restructuring and other termination costs, impairments, asset write-offs, disposals of investments and unusual operating income/(expense) that are considered rare or discrete events and are infrequent in nature, as inclusion of such items is not considered to be indicative of the Company's ongoing operating performance, and also excludes Net financial expenses/(income) and Tax expense/(benefit). Unusual operating income/(expense) are impacts from strategic decisions, as well as events considered rare or discrete and infrequent in nature, as inclusion of such items is not considered to be indicative of the Company's ongoing operating performance. Unusual operating income/(expense) includes, but may not be limited to: impacts from strategic decisions to rationalize Stellantis' core operations; facility-related costs stemming from Stellantis' plans to match production capacity and cost structure to market demand, and convergence and integration costs directly related to significant acquisitions or mergers. • Adjusted Operating Income/(Loss) Margin is calculated as Adjusted operating income/(loss) divided by Net revenues • Industrial Free Cash Flows is our key cash flow metric and is calculated as Cash flows from operating activities less: (i) cash flows from operating activities from discontinued operations; (ii) cash flows from operating activities related to financial services, net of eliminations; (iii) investments in property, plant and equipment and intangible assets for industrial activities, (iv) contributions of equity to joint ventures and minor acquisitions of consolidated subsidiaries and equity method and other investments; and adjusted for: (i) net intercompany payments between continuing operations and discontinued operations; (ii) proceeds from disposal of assets and (iii) contributions to defined benefit pension plans, net of tax. The timing of Industrial free cash flows may be affected by the timing of monetization of receivables, factoring and the payment of accounts payables, as well as changes in other components of working capital, which can vary from period to period due to, among other things, cash management initiatives and other factors, some of which may be outside of the Company’s control. In addition Industrial free cash flows is one of the metrics used in the determination of the annual performance for eligible employees, including members of the Senior Management. • Adjusted Diluted Earnings Per Share (“EPS") is calculated by adjusting Diluted earnings per share for the post-tax impact per share of the same items excluded from Adjusted operating income as well as tax expense/(benefit) items that are considered rare or infrequent, or whose nature would distort the presentation of the ongoing tax charge of the Company. We believe this non-GAAP measure is useful because it also excludes items that we do not believe are indicative of the Company’s ongoing operating performance and provides investors with a more meaningful comparison of the Company’s ongoing quality of earnings. Adjusted diluted EPS should not be considered as a substitute for Basic earnings per share, Diluted earnings per share from operations or other methods of analyzing our quality of earnings as reported under IFRS. • Industrial Net Financial Position is calculated as Debt plus derivative financial liabilities related to industrial activities less (i) cash and cash equivalents; (ii) financial securities that are considered liquid; (iii) current financial receivables from the Company or its jointly controlled financial services entities and (iv) derivative financial assets and collateral deposits. Therefore, debt, cash and cash equivalents and other financial assets/liabilities pertaining to Stellantis’ financial services entities are excluded from the computation of the Industrial net financial position. Industrial net financial position includes the Industrial net financial position classified as held for sale. July 29, 2025 H1 2025 RESULTS | 35
