Samsung SDI's Q1 battery operating loss of KRW 176.6 billion continues a KRW 60–80 billion per quarter narrowing pattern. Net profit turned positive at KRW 56.1 billion. NH Securities estimated Q1 AMPC at KRW 84.9 billion pre-earnings. Apply that figure and the underlying battery loss is roughly KRW 261.5 billion. Samsung SDI confirmed only "increased AMPC benefits." The number itself remains undisclosed.
SK On narrowed to KRW 349.2 billion operating loss, but the baseline is Q4 2025's anomalous KRW 441.4 billion. Q4 AMPC was KRW 101.3 billion. Q1 AMPC: not disclosed. The pre-incentive loss is larger than headline by an unknown margin.
