Insights
TL;DR Strong margin recovery and cash profitability driven by real estate gains and device sales; core service growth was steady but volatility rose.
Consolidated revenue growth of 13.5% and a >100% increase in operating profit are material outcomes, supported by a large increase in sale-of-goods revenue and one-time real-estate gains. EBITDA expansion to KRW 1,990.7bn and an improved operating margin indicate meaningful operating leverage. Service revenue grew modestly, suggesting core telecom demand remained stable while ancillary businesses (devices, estate, cloud) drove headline performance. Investors should note the mix effect: higher COGS and sale-of-goods swings amplify topline but may compress margins absent recurring gross-margin improvement.
TL;DR Balance-sheet leverage rose and non-operating results flipped negative; sharp COGS and sale-of-goods swings raise earnings predictability concerns.
Net debt/equity increased to 36.8% (up 3.3p YoY) and borrowings rose at subsidiaries, reflecting higher financing needs. Non-operating income moved to a loss of KRW 39.9bn on a consolidated basis, reversing prior gains. The >100% increase in sale-of-goods revenue and a 46.8% jump in COGS highlight revenue concentration risk tied to device or goods sales timing. While headline profitability improved, these items could create quarter-to-quarter volatility and warrant monitoring.
