•Consolidated shipments(1) totaled 1.3 million units, marking a 13% year-over-year increase (up 152,000 units).

•Total inventories of 1,252 thousand units (Company inventory of 363 thousand units) at September 30, 2025, +4% compared with mid-year, reflecting disciplined stock management while launching several new vehicles

•Commercial progress continues, highlighted by 6 of the 10 planned 2025 introductions launching by the end of Q3 2025, the return of the 5.7-liter HEMI® V-8-powered Ram 1500, and the ramp-up of several newly-introduced European models

•On October 14, 2025, the Company announced a strategic U.S. investment program of $13 billion over the next 4 years, aimed at fueling future growth and reinforcing its manufacturing footprint and brand presence across the U.S.

•The Company reiterates its H2 2025 financial guidance, which anticipates improvement in Net revenues, AOI(2) margin(3) and Industrial free cash flows(4).


"As we continue to implement important strategic changes in order to provide our customers with greater freedom of choice, we have seen positive sequential progress and solid year-over-year performance in Q3, marked by the return of top-line growth. This is encouraging and we are continuing to build on these gains. We are also taking decisive actions to align Stellantis’ resources, programs and plans to support long-term, profitable growth, including our recently announced $13 billion investment in the U.S." Antonio Filosa, CEO

AMSTERDAM, October 30, 2025 - Stellantis N.V. today announced its Q3 2025 results, reporting a 13% year-over-year increase in Net revenues to €37.2 billion, primarily driven by growth in North America, Enlarged Europe and Middle East & Africa, while South America saw a moderate decrease. Consolidated shipments(1) totaled 1.3 million units, up 13% (152,000 units), with most of the increase due to a 35% improvement in North America reflecting the benefits of normalized inventory dynamics, compared to the prior year in which the U.S. dealer stock reduction initiative temporarily decreased production.

Progressing Product Launches

By the end of Q3, six of the ten new vehicles planned for 2025 introduction were successfully launched. Additional launches in the fourth quarter will reintroduce several volume nameplates which exemplify important, decisive changes already made in the Company's strategy to provide customers with greater freedom to choose the cars and the configurations they want. Ordering is now open for the SIXPACK-powered Dodge Charger Scat Pack (2-door), the four-door Dodge Charger Daytona, Jeep® Cherokee, Fiat 500 Hybrid and DS No.8.

Sales momentum in the U.S. improved, with a 6% increase in Q3 sales year-over-year. This trend was evidenced across the Jeep®, Ram, Chrysler, and Dodge brands - taking the Company to a monthly market share of 8.7% in September, the highest in 15 months. Another milestone in September was the return to market of the HEMI® V-8-powered Ram 1500.

In Enlarged Europe, several recently introduced models, including the Citroën C3, C3 Aircross, Opel/Vauxhall Frontera and Fiat Grande Panda, supported an improved market share in the B-segment, underpinned by increased production. Net revenues rose 4% compared to the prior year period. Market share in EU30 fell to 15.4%, affected by market declines in France and Italy, where Stellantis has greater exposure and a moderately lower market share in the LCV segment.

Outside North America and Enlarged Europe, Stellantis delivered solid commercial results. Aggregated sales grew 6% year-over-year, led by Middle East & Africa, partially offset by South America.

Stellantis Leadership Team

On 8th October Stellantis announced a number of new appointments to its Senior Leadership Team, promoting exceptional talent from both inside and outside the Company to sharpen regional focus and drive long-term sustainable success.

$13 Billion Investment to Grow in the United States

On October 14, Stellantis unveiled a strategic $13 billion investment program for the next four years to accelerate growth and expand its manufacturing footprint in the United States. This marks the largest U.S. investment in the Company’s 100-year history and will include the launch of five new vehicles and the creation of over 5,000 jobs.

•Belvidere, Illinois, plant to reopen for production of two new Jeep® models - Cherokee and Compass

•All-new Ram midsize truck to be assembled in Toledo, Ohio

•Warren, Michigan, plant to produce all-new large SUV with both range-extended EV and internal combustion engine powertrains

•Next-generation Dodge Durango to be built in Detroit

•Kokomo, Indiana, facilities to produce all-new GMET4 EVO engine

The new investment will further expand Stellantis’ already significant U.S. footprint, increasing annual finished vehicle production by 50% over current levels. The new product launches will be in addition to a regular cadence of 19 refreshed products across all U.S. assembly plants and updated powertrains planned through 2029.

Stellantis H2 2025 Financial Guidance

Stellantis reiterates its H2 2025 financial guidance, which anticipated continued improvement in Net revenues, AOI and Industrial free cash flows compared to H1 2025.

As we continue making important and necessary changes to our strategic and product plans, also in response to regulatory, geopolitical, macro-economic and other external and internal developments, we anticipate incurring charges in H2 2025, which, once finalized, we expect will largely be excluded from AOI.

We have also initiated a review of our warranty estimation process, which we expect to result in changes in those estimates and one-off charges in H2 2025.

Upcoming Events

On October 30, 2025, at 1:00 p.m. CET/8:00 a.m. EDT, a live webcast and conference call will be held to present Stellantis' Third Quarter 2025 Shipments and Revenues, with the presentation expected to be posted at approximately 8:00 a.m. CET/3:00 a.m. EDT.

NOTES

(1) Combined shipments include shipments by the Company's consolidated subsidiaries and unconsolidated joint ventures, whereas Consolidated shipments only include shipments by the Company's consolidated subsidiaries. This includes the vehicles produced by our joint ventures and associates (including Leapmotor) which are distributed by our consolidated subsidiaries. In addition to the volumes included in consolidated shipments, combined shipments also includes the vehicles distributed by our joint ventures (such as Tofas). Figures by segments may not add up due to rounding.

(2) 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.

(3) Adjusted operating income/(loss) margin is calculated as Adjusted operating income/(loss) divided by Net revenues.

(4) 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 bonus for eligible employees, including members of the senior management.
