Sinopec Oilfield Service Guarantees Total RMB 28.625 Billion

Sinopec Oilfield Service Corp. (Sinopec Oilfield Service) provided RMB 2.45 billion in credit and performance guarantees for its wholly-owned subsidiaries and joint venture, DS Servicios Petroleros, S.A. de C.V., in the first half of 2025. This amount represents 28.34% of the company's latest audited net assets. As of June 30, 2025, the cumulative outstanding guarantee balance reached RMB 28.625 billion.

A key point to note is that some guaranteed entities have a debt-to-asset ratio exceeding 70%. While a 50% counter-guarantee exists from DIAVAZ DEP, S.A.P.I. de C.V. for the joint venture's performance guarantee, all other guarantees lack such an arrangement. There are currently no overdue external guarantees.
