S-1 logs slight sales dip as one-off costs slash Q1 profit in South Korea

S-1 announced its preliminary operating results for the first quarter of 2026.

S-1 disclosed on the 30th that, on a consolidation basis, first-quarter revenue was provisionally tallied at 673.7 billion won. That was down 0.1% from a year earlier.

Operating profit came to 20.7 billion won, down 62.4% from 55.1 billion won a year earlier. One-off retirement benefit expenses related to lawsuits over average wages were reflected in the first quarter.

An S-1 official said, "The decline in operating profit is a temporary effect from one-off expense factors," and added, "There is no impact on business fundamentals, including solid growth in the security segment and increased new orders in building management."
