Amendment deed (the "Amendment Deed") to upsize the capacity for its 2025 Convertible Notes (the "2025 Notes") from US$100 million to US$130 million; a further subscription by an existing investor for an additional 2025 Note in the amount of US$15 million; and the transfer of an existing 2025 Note to a new investor.

The 2025 Notes were issued pursuant to a convertible note purchase agreement (the "2025 Note Purchase Agreement") entered into between the Company and an initial investor (the "Initial Investor") on November 3, 2025 as part of a refinancing of previous convertible notes issued in 2022. The 2025 Note Purchase Agreement contemplated the issuance and sale by the Company of up to US$100 million of 2025 Notes. Of this, the Initial Investor purchased US$35 million (the "Initial Note") and the remaining principal amount was fully subscribed for during the course of Q4 2025 and Q1 2026. The conversion price of the 2025 Notes is US$2.62 (subject to customary adjustments on the conversion price) and will be due in 2028.

The Initial Investor subsequently transferred US$15 million of the Initial Note to an international investment bank and securities firm outside China.

On Jul. 16, 2026, the Company entered into the Amendment Deed, which amends the total potential size of the 2025 Notes from US$100 million to US$130 million. Following the amendment, the Initial Investor agreed to subscribe for a new 2025 Note in the principal amount of US$15 million.

Mr. Ziyu Shen, Founder and CEO of ECARX commented: "The upsizing of our 2025 convertible note program and the continued institutional investor endorsement announced today strongly validates capital market confidence in ECARX's core technology competitiveness and long-term global growth roadmap. The incremental capital raised will support the continuous iteration, R&D upgrade and commercial scaling of our full-stack automotive intelligence platform, further strengthen our balance sheet, and drive sustainable long-term shareholder value creation."
