ECARX and SiEngine: A Partnership Driving Automotive Innovation

In an impressive display of growth, SiEngine Technology Co., Ltd., an automotive semiconductor company incubated by ECARX Holdings Inc. (Nasdaq: ECX), has recently secured $200 million in equity financing. This funding marks a pivotal moment, not only for SiEngine but also as a substantial endorsement of ECARX's strategy in cultivating and integrating innovative technologies for software-defined vehicles (SDVs).

Investment Highlights

The investment comes from a diverse group of institutional investors during the first half of 2026, reinforcing SiEngine's position among China's premier designers of chips meant for vehicles. This financial boost signals strong confidence in SiEngine's ability to innovate and deliver high-performance solutions tailored for the rapidly evolving automotive market.

Co-founded in 2018 by ECARX and Arm China, SiEngine has transitioned into a fully-fledged automotive semiconductor enterprise, with ECARX remaining the largest shareholder. The dual focus on creating vehicle-grade silicon chips optimized for ECARX's unique ecosystem of software-defined vehicles aims to provide automotive manufacturers with significant cost-performance benefits in intelligent mobility platforms.

Next Steps for SiEngine

The recent funding will target several critical aspects of SiEngine's future. Key areas of investment include:

• - Research and Development (R&D): Enhancing technology at a rapid pace to keep up with global automotive demands.
• - Production Capacity Expansion: Scaling manufacturing capabilities to meet increasing orders and demands from the automotive sector.
• - Globalization: Exploring international markets and customer bases to widen their reach and potential growth.

A Synergistic Approach to Technology

The partnership between ECARX and SiEngine has resulted in the creation of an integrated technology platform that combines SiEngine's Longying series system-on-chips (SoCs) with ECARX's Antora® central computing platforms. This collaboration delivers on-demand chip-and-software solutions that are mature and ready for deployment across various global automotive models.

One of the standout achievements includes powering dozens of vehicle models such as Geely Galaxy, Lynk & Co, and FAW Hongqi with Antora® solutions utilizing the 7nm Longying I chip. This level of integration has positioned the partnership as a frontrunner in the semiconductor landscape for SDVs.

Revolutionary Innovations on the Horizon

SiEngine has recently introduced its 5nm Longying II cabin-driving fusion SoC, which boasts capabilities such as native large language model functionality and enhanced AI computation performance. This innovative chip is specifically designed for the next-generation Antora platforms and Flyme Auto OS, establishing a new industry benchmark in China's software-defined vehicle ecosystem.

Expanding Horizons Beyond Passenger Vehicles

What's more, ECARX and SiEngine are diversifying their technological footprint. Strategic alliances with manufacturers of commercial vehicles and robotaxis are expanding their collective market presence. The unified silicon solutions now cater to a broad spectrum of applications—from passenger cars to commercial fleets and sophisticated autonomous driving features—greatly enlarging their target market.
