KEPCO posts strong Q3 and 9M profit rebound on higher margins.

KEPCO delivered stronger earnings in Q3 2025: operating income rose to KRW 5,652 billion from KRW 3,396 billion, and net income to KRW 3,790 billion from KRW 1,880 billion. Revenue increased to KRW 27,572 billion, indicating improved spread versus costs.
