Issuer Overview

• Korea East-West Power Co., Ltd. (EWP) is a Korean power-generation company separated from Korea Electric Power Corporation (KEPCO) in April 2001 during the restructuring of Korea's power industry.
• KEPCO owns 100% of EWP. EWP should be treated as a government-related KEPCO generation subsidiary, not as a private independent power producer and not as a direct Korean government obligation.
• EWP sells electricity to KEPCO through the Korea Power Exchange (KPX) rather than directly to retail customers.

Core Credit View

• EWP's supported credit profile is anchored in KEPCO ownership, Korea's electricity supply framework, institutional sales through KPX/KEPCO, domestic AAA ratings, and international high-grade ratings.
• Standalone credit quality is constrained by a thermal-heavy generation mix, coal and LNG fuel exposure, environmental and transition investment, short-term refinancing needs, and the absence of a confirmed direct government guarantee on ordinary EWP bonds.
• The key credit distinction is between EWP's standalone generation-company profile, parent support from KEPCO, broader Korean government support incentives for the electricity system, and the legal protections of each individual bond.

Business and Franchise View

• EWP operates domestic generation assets mainly in Dangjin, Ulsan, Donghae, and Ilsan.
• Installed capacity was 9,675MW as of end-March 2025. The capacity mix in the data file is steam thermal 6,440MW, combined-cycle 2,972MW, and alternative energy 263MW.
• Dangjin coal power is the core generation asset. LNG combined-cycle assets at Ulsan and Ilsan are important transition and flexibility assets, while alternative energy remains small in the current capacity mix.
• EWP forms part of KEPCO group's non-nuclear generation base. Its individual market share is not irreplaceable on a national basis, but disruption to the generation subsidiaries as a group would matter for Korean electricity supply.

Capital Structure and Structural Points

• EWP is a wholly owned KEPCO subsidiary. The support route is best viewed as Korean government -> KEPCO -> generation subsidiaries.
• KEPCO-related legal and policy materials support the parent and electricity-system context, but they should not be used as evidence that EWP's ordinary bonds are automatically government-guaranteed.
• Specific USD and domestic bond documents must be checked separately for issuer, guarantee, ranking, negative pledge, cross default, change of control, tax, governing law, listing market, and any explicit government or KEPCO guarantee language.

Liquidity and Funding View

• FY2025 DART figures showed continued profitability and positive operating cash flow. The data file records the detailed FY2025 extracted metrics and simple calculated ratios.
• At end-2025, cash and current financial assets were materially below short-term borrowings and bonds, so liquidity should be assessed through market access, bank facilities, KEPCO/government support expectations, and refinancing capacity rather than on-hand cash alone.
• EWP has high-grade domestic and international market access, but maturity schedules, foreign-currency debt, hedging, committed lines, and detailed bank facilities remain key data gaps.

Credit Strengths

• 100% KEPCO ownership and strong government-related status.
• Institutional electricity sales to KPX/KEPCO under Korea's power market framework.
• Meaningful generation capacity within Korea's electricity system.
• FY2024-FY2025 profitability recovery and positive FY2025 operating cash flow.
• Domestic AAA rating and high international rating levels as public checks.

Credit Weaknesses

• Thermal-heavy generation mix, including material coal and anthracite exposure.
• Sensitivity to fuel prices, SMP, settlement adjustment factors, KEPCO's financial condition, and electricity policy.
• Ongoing power-transition and environmental investment requirements.
• Thin direct liquidity compared with short-term debt.
• Support expectations are strong, but explicit legal guarantees on individual bonds are unconfirmed.

Rating Watchpoints

• KIS confirmed domestic unsecured bonds at AAA/Stable in the 2025-06-17 Credit Opinion.
• S&P public list confirmed AA/Stable; Moody's public summary confirmed Aa2/Stable; Fitch public release mirrors confirmed AA-/Stable in prior releases.
• Latest full Moody's, S&P, and Fitch reports were not reviewed in the current report cycle. Support assumptions, standalone assessment, and rating triggers need to be confirmed from full reports when available.
• A sovereign downgrade, KEPCO rating deterioration, weaker support assumptions, or material standalone deterioration could affect ratings and spreads.

Recurring Analytical Cautions

• Do not treat domestic AAA or international high ratings as evidence that EWP's standalone credit quality alone is equivalent to the rating level.
• Do not describe EWP ordinary debt as Korean government-guaranteed unless the relevant bond document contains explicit guarantee language.
• Do not overstate the 2024-2025 earnings recovery as permanent; it benefited from the fuel-cost and settlement environment and needs confirmation in later filings.
• Use live bond and spread data only when specifically checked; current issuer memory does not contain relative-value evidence.

Reliable Core Sources

• EWP official English website and business pages for company profile, domestic generation mix, overseas business, renewable business, financial report navigation, and ESG bond context.
• DART corrected FY2025 annual report, filed 2026-03-31, receipt number 20260331004279, for FY2025 financial statements and cash-flow extraction.
• KEPCO FY2025 Form 20-F for group structure, generation asset context, and Korean electricity system context.
• KIS Credit Opinion dated 2025-06-17 for domestic rating, financial history, debt structure, capex, and support rationale.
• KPX electricity market materials, Electric Utility Act translation, and KEPCO Act exhibit for market and legal-framework context.

Ongoing Follow-Up Items

• Complete remaining FY2025 DART extraction: bond maturity profile, foreign-currency debt, hedging, committed lines, bank facilities, and detailed capex notes.
• Track Eumseong LNG combined-cycle investment, Dangjin coal-yard indoor conversion, environmental equipment upgrades, Guam Ukudu, renewables, and other new-business capex.
• Monitor fuel costs, LNG and coal prices, KRW movements, SMP, capacity payments, settlement adjustment factors, and KEPCO's tariff and financial condition.
• Track domestic KIS/NICE/KR ratings and international Moody's/S&P/Fitch actions, especially any change in parent-support assumptions.
• Review offering circulars or shelf/registration documents before any specific bond recommendation.

Unresolved Issues and Items to Check Next Time

• Whether FY2025 operating cash flow and simple FCF improvement continued in 2026 quarterly filings.
• Whether short-term borrowings remained lower after the 1Q2025 refinancing and MMF-related movement noted by KIS.
• Current maturity profile for domestic bonds and USD notes.
• Latest full Moody's, S&P, and Fitch reports, including standalone assessment, support uplift, and rating triggers.
• Whether any specific outstanding USD notes are explicitly guaranteed, or are only senior unsecured EWP obligations.
• Live bond prices, spreads, OAS, Z-spread, CDS, and same-tenor comparisons with KEPCO, KOGAS, KNOC, KDB, and Korean sovereign bonds.

Analytical Cautions

• Keep EWP's standalone generation-company profile, KEPCO parent support, Korean government support incentives, and individual bond legal protections separate.
• Treat the FY2024-FY2025 profitability recovery as a confirmed improvement, but not as proof of permanent structural improvement until later filings confirm persistence.
• Do not analyse EWP as a private IPP; its revenue base is institutional and linked to KPX/KEPCO.
• Do not analyse EWP as a direct Korean government obligation unless the relevant instrument document provides explicit guarantee language.
• Pay particular attention to settlement adjustment factors and KEPCO's financial position, because policy and group-level pressure can reach generation subsidiaries.

Report Wording Cautions

• Use "support-inclusive high-grade Korean quasi-sovereign" or similar wording only when the distinction from explicit government guarantee is clear.
• Avoid language implying that the KEPCO Act or Korea's electricity policy automatically guarantees EWP debt.
• When discussing ratings, say that rating levels include support assumptions; do not attribute the full rating level to standalone credit quality.
• If live spreads have not been checked, state that relative-value cheapness or richness is unverified.

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

• Eumseong LNG, environmental upgrades, renewable projects, and overseas projects are the main investment topics that may affect debt and FCF.
• Confirm whether management indicates investment deferrals, asset sales, additional funding support, or changes in dividend/capital policy in future disclosures.
• Overseas projects should remain secondary to the domestic generation framework unless financial exposure, guarantees, or construction delays become clearer.

Items to Check for Ratings and Bond Investors

• Bond-level guarantee, ranking, negative pledge, cross default, change of control, tax gross-up, governing law, listing venue, and event-of-default language.
• Whether international rating reports continue to treat EWP as a core KEPCO subsidiary and how they assess legal, strategic, and operational support incentives.
• Whether market access remains stable across domestic KRW bonds and foreign-currency notes during periods of Korean quasi-sovereign spread widening.
