VOLUNTARY ANNOUNCEMENT

AGREEMENT ON EXPANDING E/E ARCHITECTURE TECHNICAL

COLLABORATION WITH VOLKSWAGEN GROUP

Reference is made to the announcement of XPeng Inc. (the “Company” or “XPENG”) dated July 22, 2024 in connection with the Master Agreement on E/E Architecture Technical Collaboration. XPENG and the Volkswagen Group are pleased to announce that, following the execution of Master Agreement on E/E Architecture Technical Collaboration on July 22, 2024 (the “Master Agreement on E/E Architecture Technical Collaboration”), XPENG and the Volkswagen Group have accelerated the joint development of the industry-leading E/E Architecture at “China Speed” and achieved key milestones. Based on the shared strategic objective to expand the application scope of the E/E Architecture within the Volkswagen Group and realize cross-platform and cross-powertrain platformization, both parties have entered into an Agreement on Expanding E/E Architecture Technical Collaboration (the “Expanded Technical Collaboration”). The signing of this agreement marks that the E/E Architecture will be not only integrated into Volkswagen’s electric vehicle platforms, but also deployed across its ICE (Internal Combustion Engine) and PHEV (Plug-in Hybrid Electric Vehicle) platforms in China, thereby significantly expanding the strategic technical collaboration to broader markets.

The Expanded Technical Collaboration will further accelerate the Volkswagen Group’s software-defined vehicle strategy execution and enhance its global competitiveness. Such cross-platform and cross-powertrain platformization of the E/E Architecture will enable the Volkswagen Group to achieve faster software iteration and Over-the-Air (“OTA”) updates, and significantly shorten vehicle development cycle.

Adhering to rigorous platform-oriented design philosophy, the joint R&D teams have designed and validated that the E/E Architecture developed for electric vehicle platforms can also be adapted to ICE and PHEV platforms. This technical solution represents a major milestone in joint technical collaboration, demonstrating the synergy and strategic value of the long-term partnership between both parties. The Expanded Technical Collaboration will significantly expand the scale of vehicles equipped with this industry leading E/E Architecture in China market, enabling the Volkswagen Group to realize significant platform-driven economies of scale and enhanced product competitiveness.

“The Expanded Technical Collaboration marks a significant milestone in the ongoing strategic collaboration between XPENG and the Volkswagen Group, following the signing of the Master Agreement on E/E Architecture Technical Collaboration on July 22, 2024. This Expanded Technical Collaboration not only underscores the mutual trust in our long-term strategic partnership but also highlights our commitment to and vision for continuous innovation in smart electric vehicle technologies.” said Mr. Xiaopeng He, Chairman and CEO of XPENG.
