Xinchen China Power Holdings Limited has signed a supplemental agreement with its 31.20 %-shareholder Brilliance China Automotive Holdings Limited to lift purchasing caps for engine components in the remaining two years of their 2025–27 framework agreement.

Key revisions • Fiscal-year 2026 cap lifted to RMB3.82 million from RMB2.35 million. • Fiscal-year 2027 cap lifted to RMB9.33 million from RMB1.76 million.

Drivers of the uplift • Spending under the agreement already reached RMB3.65 million in 2025 and RMB2.02 million in the eight months to 31 August 2026, leaving only RMB0.33 million of headroom against the FY2026 cap. • Management expects higher component requirements as demand for Xinchen China Power’s conventional engines from customers other than Li Auto Inc. continues to rise. • Additional orders from new customers are anticipated for 2027, necessitating greater procurement flexibility.

Regulatory positioning • Brilliance China’s 31.20 % stake in Xinchen makes the transactions connected dealings under Hong Kong Listing Rules Chapter 14A. • Even after the uplift, the annual percentage ratios remain above 0.1 % but below 5 %; the revised caps therefore require announcement and annual review but are exempt from circular, independent financial advice and shareholder-approval obligations. • Chairman Zhang Wei and Non-executive Director Huang Yu, who also hold senior positions at Brilliance China, abstained from the board vote; all other directors approved the changes.

Operational context • The purchased components are used in Xinchen China Power’s engine production and aftermarket sales. • Despite softer overall engine sales in 1H 2026 due to reduced range-extender orders for Li Auto, growing volumes from other OEM clients have tightened component supply. • Maintaining specification-matched parts from Brilliance China was cited as critical to production continuity.

All other provisions of the Brilliance China Purchase Agreement 2025–27 remain unchanged following the 8 September 2026 supplemental agreement.
