Revenue rose 5.7 percent from a year earlier and operating profit increased 3.4 percent.

Net profit rose 61.9 percent from a year earlier to 509.2 billion won, reflecting a base effect from asset impairment losses at subsidiary LG HelloVision in 2024. Earnings before interest, tax, depreciation and amortisation (EBITD) rose 1.8 percent to 3.59 trillion won.
