CK SAN-ETSU Co.,Ltd. [5757.T]

TOKYO, Feb 13 (Pulse News Wire) – CK San-etsu CO.,LTD. (5757.T) reported derivative losses and valuation losses totaling ¥77 billion for its fiscal third quarter ending December 31, 2025.

Specifically, the company recorded a derivative loss of ¥20 billion and a derivative valuation loss of ¥57 billion due to rising copper prices since October 2025. The company engages in derivative transactions aimed at mitigating price fluctuation risks associated with primary raw materials such as copper and zinc, which are subject to international commodity markets.

However, recent sharp increases in copper prices led to these significant non-operating expenses. Looking ahead, CK SAN-ETSU noted that future costs could vary depending on ongoing raw material market conditions.

Investors should consult the company's recently released earnings forecast update for further guidance on projected consolidated performance for the fiscal year ending March 2026.
