[6-K] KT CORP Current Report (Foreign Issuer)

Rhea-AI Filing Summary

KT Corporation furnished a Form 6-K with its 3Q25 results, showing solid year-over-year growth. Consolidated operating revenue was KRW 7,126.7bn (up 7.1% YoY) and operating income reached KRW 538.2bn (up 16.0%). Service revenue came in at KRW 5,920.8bn, and net income was KRW 445.3bn (up 16.2%). EBITDA totaled KRW 1,503.9bn.

Profitability benefited from real estate projects and group portfolio gains as operating expenses rose 6.4% YoY.

Operationally, wireless service revenue rose 4.7% YoY with 5G penetration 80.7%, broadband grew 2.3% YoY, and media increased 3.1% YoY. Subsidiaries posted mixed trends: kt cloud +20.3% YoY and kt estate +23.9% YoY revenue. KT outlined AI/IT transformation goals toward FY2028 and announced security enhancements, including an investment of KRW 1tn over five years and customer compensation tied to recent incidents.

Insights

Telecom equity analyst

Steady 3Q growth with dividend continuity and stronger mix.

KT delivered YoY growth in revenue and operating income, aided by telecom, cloud/data center, and real estate contributions. Wireless service revenue growth and 5G penetration at 80.7% suggest stable ARPU support alongside broadband and media gains.

Costs increased, but operating income still rose 16.0% YoY, while borrowings declined QoQ and net debt/equity moved to 34.5%. Subsidiaries like kt cloud (+20.3%) and kt estate (+23.9%) provided incremental lift.

Capital returns continue via a 3Q25 dividend of KRW 600 DPS (’25 YTD KRW 1,800). Strategy highlights include AI/IT transformation and a planned KRW 1tn five-year security investment; actual impact depends on execution within core telco and B2B lines.
