Report date: 2026-08-06 Event date: 2026-08-05 Event title: Q2 2026 Results

1. Flash Conclusion

SK Telecom's Q2 2026 result is credit supportive: consolidated operating income reached KRW566.0bn, the second successive quarter above KRW500bn, while handset additions continued, churn improved and SK Broadband delivered higher revenue and earnings. It does not establish a fully structural recovery: the 67.3% year-on-year operating-income increase benefits from the low Q2 2025 base, when USIM replacement and retail-store compensation costs burdened earnings. Revenue growth was only 0.5%, mobile service revenue fell 1.9%, and marketing expense increased.

The credit view therefore improves modestly on operating momentum but remains conditional on cash-flow conversion and customer recovery. Cash and short-term financial instruments rose to KRW2,003.4bn, while reported bonds payable and long-term borrowings remained broadly stable at KRW7,582.6bn. The materials do not provide a reconciled net-debt, free-cash-flow, maturity or committed-facility position. The KRW830-per-share dividend was maintained for a second quarter and should be assessed against residual cyber costs, network investment, AIDC development spending and refinancing needs.

AIDC revenue increased 92.5% year on year to KRW136.2bn and SK Telecom established SK Hyper in July to secure sites, power infrastructure and tenants. This supports diversification, but the stated phased 5GW AIDC objective from 2029 creates a much larger exposure to project capex, power availability, tenant commitments, funding and return discipline. The Q2 release does not detail these items sufficiently to treat the expansion as an immediate credit benefit.

2. Q2 Results: Profit Recovery with a Limited Revenue Advance

KRW bn unless stated Q2 2026 Q2 2025 YoY Q1 2026 QoQ Credit read-through
Consolidated revenue 4,359.1 4,338.8 0.5% 4,392.3 -0.8% Stable top line, but limited organic growth at the group level.
Operating income 566.0 338.3 67.3% 537.6 5.3% Strong sequential performance; YoY comparison benefits from Q2 2025 incident-response costs.
EBITDA 1,442.3 1,232.7 17.0% 1,416.2 1.8% Supports earnings recovery, although cash-flow conversion needs confirmation.
Net income 466.0 83.2 459.8% 316.4 47.3% Improved earnings, but net income is not a substitute for FCF or liquidity analysis.
Capex 487.0 635.0 -23.3% 136.5 256.7% Q2 investment rose from Q1; full-year capex and AIDC commitments remain important.

Consolidated operating income rose 5.3% quarter on quarter, following KRW537.6bn in Q1, and the reported EBITDA margin improved to 33.1% from 28.4% in Q2 2025. The operating turnaround is meaningful because it follows the weak 2025 period in which subscriber trust, compensation and incident-response costs put pressure on the telecom franchise. It is also helpful that operating expenses declined 5.2% year on year while revenue was broadly stable.

The year-on-year comparison nevertheless needs careful interpretation. Management explicitly attributes part of the operating-profit increase to the absence of the prior-year USIM-replacement cost base. Q2 2025 operating income was KRW338.3bn, when the company faced one-off replacement and retail-store compensation expenses. The Q2 2026 outcome consequently provides stronger evidence of normalising profitability than of a complete reduction in the long-run cost of the incident. The current disclosure does not reconcile remaining customer compensation, regulatory, litigation, insurance or security-investment cash costs. It should not be read as confirmation that the incident has no further credit effect.

At 30 June 2026, cash and short-term financial instruments were KRW2,003.4bn, compared with KRW1,733.9bn at 31 March, while bonds payable and long-term borrowings were KRW7,582.6bn, broadly unchanged from the previous quarter-end. These balances are useful but insufficient for a conclusion on financial flexibility because the briefing does not provide operating cash flow, maturity concentration, undrawn lines, currency hedging or post-dividend free cash flow.

3. Customer Recovery and Fixed-Line Support

Mobile service revenue declined 1.9% year on year to KRW2,563.4bn and 0.2% quarter on quarter. This prevents the report from characterising Q2 as a broad-based mobile-revenue recovery. However, handset subscribers increased by 12,000 sequentially to 21.970mn, following Q1 additions, and monthly churn fell to 0.8% from 1.6% in Q2 2025. The 5G subscriber base rose to 17.973mn, up 5.6% year on year. These data are directionally positive for franchise stabilisation after the incident and more persuasive than a single Q1 data point.

Marketing expense increased 3.1% year on year to KRW747.7bn, while ARPU was effectively flat at KRW29,098. The release attributes net additions to customer-value initiatives and notes an integrated 5G/LTE pricing-plan reorganisation in July, but does not quantify its incremental cost or revenue effect. Sustained net additions and lower churn would be credit positive if achieved without prolonged pressure on service revenue, marketing cost or cash flow; Q2 alone is not enough to establish that outcome.

SK Broadband supports consolidated diversity: revenue rose 3.6% to KRW1,160.3bn and operating income 44.3% to KRW132.5bn, with broadband subscribers up 2.4% to 7.348mn. Pay-TV and enterprise revenue declined modestly, however. The allocation of SK Broadband cash flows and debt obligations between legal entities, and the implications for any particular creditor, require entity-level and bond-document review.

4. AIDC: Diversification Opportunity and Development Burden

AIDC revenue was KRW136.2bn, up 92.5% year on year and 3.6% sequentially, helped by higher data-centre utilisation and submarine-cable revenue. AI B2B/B2C revenue also increased 24.5% to KRW61.3bn. The acceleration is positive because it broadens the revenue mix beyond mature mobile services and illustrates that prior AI investment is generating visible revenue. However, the business remains small relative to consolidated revenue, and the materials do not disclose AIDC EBITDA, operating cash flow, tenant concentration, contract tenor, project-level utilisation or returns.

The establishment of 100%-owned SK Hyper changes the focus from near-term AIDC revenue to development execution. It is intended to secure land and power infrastructure, develop projects and attract tenants, while the group targets phased openings from 2029 and a combined 5GW initial capacity goal. The disclosure does not explain committed funding, guarantees, debt location, contract coverage or capital-allocation limits. SK Hyper should therefore be monitored as a potential future growth and capex driver, not as a source of de-risked cash flow.

5. What To Watch Next

First, Q3 reporting should confirm whether mobile service revenue, ARPU, handset additions and churn improve together, and whether marketing costs remain proportionate to retention and acquisition benefits. The July price-plan reorganisation deserves particular attention because it may affect both customer value and revenue trends.

Second, investors should obtain an updated reconciliation of incident-related provisions, compensation, litigation, regulatory measures, insurance recoveries and cybersecurity investment. A second strong earnings quarter does not by itself settle the remaining cash-flow and franchise risks.

Third, Q3 and any interim filing should be used to assess operating cash flow, capex, dividends, net debt, short-term debt, debt maturities, committed facilities and FX liquidity. This is necessary to judge whether the dividend and investment programme are absorbable within recurring telecom cash generation.

Finally, SK Hyper's project pipeline should be tracked through disclosed power access, sites, signed tenants, capex, financing structure, project timing, contract terms and anticipated returns. These are the items needed to decide whether the AIDC expansion preserves SK Telecom's financial discipline or becomes a material development burden.
