Issuer Overview

• SK Broadband Co., Ltd. is a Korean fixed-line telecommunications, pay TV, enterprise connectivity and data-centre company under SK Telecom.
• The bond ticker reference used in this workspace is HATELE.
• SK Telecom acquired additional SK Broadband shares in May 2025, raising its ownership to 99.14%.
• On 26 March 2026, SK Telecom resolved to implement a share exchange to make SK Broadband a wholly owned subsidiary, with the transaction scheduled for 29 May 2026.
• SK Broadband should be analysed as a strategic SK Telecom fixed-network, pay TV and B2B / data-centre subsidiary, not as a standalone cable TV company or a pure-play data-centre company.

Core Credit View

• SK Broadband is a high-quality domestic Korean telecom subsidiary credit supported by defensive fixed-line / pay TV cash flow and expected support from SK Telecom.
• The core credit tension is stable EBITDA and parent integration versus mature IPTV / pay TV growth, data-centre investment, dividends, rising net debt and unverified individual bond terms.
• KIS assigns AA/Stable to unsecured bonds and A1 to commercial paper / short-term bonds, incorporating the possibility of extraordinary support from SK Telecom.
• Expected parent support is a rating and analytical support factor, but it is not a confirmed contractual guarantee for HATELE bonds.

Business and Franchise View

• SK Broadband operates high-speed internet, IPTV, cable TV, fixed-line telephony, enterprise telecommunications and data centres.
• KIS positions SK Broadband as the No. 2 fixed-line and pay-TV operator after KT.
• As of the KIS-sourced data in local JSON, the company had about 7.20 million high-speed internet subscribers at end-September 2025, about 3.29 million fixed-line phone subscribers at end-September 2025, about 6.70 million IPTV subscribers at end-June 2025 and about 2.77 million cable TV subscribers at end-June 2025.
• High-speed internet and enterprise connectivity are relatively stable; IPTV is mature; cable TV and fixed-line telephony face structural decline.
• Enterprise telecommunications and data centres provide growth potential, but data-centre investments are capital intensive.

Capital Structure and Structural Points

• Public bond references include SK Broadband USD 4.875% 2028 senior unsecured notes, ISIN XS2629403499, USD300mn, maturing 2028-06-28.
• Public bond references also include domestic KRW bonds such as HATELE 4.872% 2026 and HATELE 3.885% 2027.
• The USD 2028 offering circular was not obtained in the current workflow, so guarantee, negative pledge, cross default, change of control, security, subordination, tax and redemption terms remain unverified.
• SK Telecom's ownership and strategic incentive should be separated from legal recourse, keepwell, parent guarantee, liquidity support agreement or capital-injection commitment.

Liquidity and Funding View

• SK Broadband's operating cash flow has been stable, with EBITDA margin around the low 30% range in the historical KIS data.
• At 9M2025, KIS-sourced data showed operating revenue of KRW3.3758tn, operating profit of KRW277.0bn, EBITDA of KRW1.0529tn, total debt of KRW2.8707tn, net debt of KRW2.2345tn and net debt / EBITDA of 1.6x.
• Debt and net debt have risen since 2023 because stable operating cash flow has been partly absorbed by dividends and data-centre investment.
• SK Telecom's Q1 2026 results disclosed SK Broadband revenue of KRW1.1498tn and operating profit of KRW116.6bn, up 3.2% and 21.4% year on year.
• End-Q1 2026 SK Broadband cash, total debt, net debt, capex, dividends and FX hedging were not confirmed from the SK Telecom Q1 release alone.

Credit Strengths

• Large fixed-line telecom, IPTV and enterprise subscriber / customer base.
• Defensive demand characteristics for residential and enterprise connectivity.
• Integration with SK Telecom's brand, sales channels, bundled products and AI / data-centre strategy.
• Domestic AA/Stable KIS rating and support-uplift rationale.
• B2B and data-centre growth potential if utilisation, contract tenor and investment payback are adequate.

Credit Weaknesses

• Fixed broadband and pay TV operate in a mature Korean market with limited subscriber growth.
• IPTV growth is slowing, while cable TV and fixed-line telephony are structurally declining.
• Data-centre acquisitions and AI data-centre investment can increase net debt before EBITDA contribution is confirmed.
• Dividends and parent-driven capital policy can limit debt reduction even when operating cash flow is stable.
• USD bond terms, foreign-currency liquidity and hedging remain unverified.

Rating Watchpoints

• KIS monitoring includes EBITDA margin and net debt / EBITDA; the Q1 flash noted KIS downgrade-direction indicators of EBITDA margin below 24% or net debt / EBITDA above 2.0x.
• Latest NICE Ratings and Korea Ratings full reports were not confirmed.
• No standalone international rating for SK Broadband was confirmed in the current workflow.

Ongoing Follow-Up Items

• Check SK Broadband's 2025 audited annual filing / DART original and detailed debt and bond maturity schedule.
• Check SK Broadband standalone or consolidated Q1 2026 financial statements for cash, total debt, net debt, short-term debt, dividends, capex and FX hedging.
• Confirm completion of the planned wholly owned subsidiary transaction scheduled for 2026-05-29 and review post-completion capital policy, dividends, related-party transactions and any parent support documents.
• Monitor high-speed internet, IPTV, pay TV, enterprise and data-centre revenue from Q2 2026 onward.
• Track whether the Q1 2026 revenue and operating-profit improvement continues after the low Q4 2025 base effect.

Unresolved Issues and Items to Check Next Time

• USD 4.875% 2028 offering circular, including parent guarantee, keepwell, negative pledge, cross default, change of control, collateral, subordination, tax gross-up and early redemption provisions.
• NICE Ratings and Korea Ratings latest full reports, and whether their concerns differ from KIS.
• Unused committed bank facilities, secured debt, short-term market funding reliance, foreign-currency debt, foreign-currency cash and hedging.
• Contracted customers, utilisation, power-cost pass-through, construction costs and investment payback for Ulsan AI data center, Gasan data center, Pangyo data center and other facilities.
• Live bond price, yield, spread, OAS and relative value versus Korean telecom, quasi-sovereign and domestic AA-rated issuers with similar maturities.

Analytical Cautions

• Do not confuse SK Telecom ownership / support expectation with an explicit guarantee on HATELE bonds.
• Near-full ownership by SK Telecom strengthens support incentives, but can also increase parent-driven dividends, related-party transactions or intra-group asset transfers.
• Data centres are not automatically credit-positive; utilisation, contract tenor, power costs, depreciation and funding method determine whether they improve or weaken credit quality.
• Stable operating revenue and EBITDA can coexist with gradually weaker capital structure if dividends and investment absorb cash flow.
• Q1 2026 profit improvement does not confirm leverage improvement because end-Q1 debt, cash, capex, dividends and hedging were not verified.

Report Wording Cautions

• Use "expected parent support" or "support uplift" rather than "parent guarantee" unless the relevant document proves a guarantee.
• Describe SK Broadband as a defensive fixed-line telecom and pay TV subsidiary with B2B / data-centre growth exposure, not as a high-growth data-centre pure play.
• When using domestic AA/Stable, state that it is a Korean domestic rating scale and should not be mechanically converted into an international rating.
• When referring to Q1 2026, state that operating profit improved but leverage and liquidity details remain unconfirmed.

Follow-Up on Management Strategy, Investment Plans, and Financial Policy

• Review the funding method and expected payback for Pangyo data center, Ulsan AI data center and any additional data-centre investments.
• Monitor whether enterprise / data-centre growth offsets IPTV maturity, cable TV decline and fixed-line telephony decline without weakening leverage.
• Track dividend policy after full ownership by SK Telecom, especially whether stable operating cash flow is used for debt reduction or upstreamed to the parent.
• Watch SK Telecom group strategy after the 2025 USIM information leak, including subscriber recovery costs, customer trust measures and bundled-product churn.

Items to Check for Ratings and Bond Investors

• Verify all HATELE bond terms before any issue-specific recommendation: issuer, guarantee, security, ranking, negative pledge, cross default, change of control, tax, governing law, FX and redemption.
• Check whether KIS, NICE Ratings and Korea Ratings maintain a consistent support view after the Q1 2026 result and full-ownership transaction.
• Monitor whether net debt / EBITDA moves toward the 2.0x area or EBITDA margin approaches KIS downgrade-direction indicators.
• Compare USD 2028 bond spread only after confirming OC terms, FX liquidity and live market levels.
