Is KEP a Buy or a Sell? The Bull and Bear Case (2026)

That depends on which case you find more convincing, and both are on this page. The bull case rests on Tariffs that cover cost, and the reform behind them, with revenue (ttm) at ~KRW 97.6 trillion (~$69B). The bear case rests on the controlling shareholder and the price regulator are the same government, and Korea has repeatedly capped the quarterly fuel cost adjustment when household bills got politically difficult, which is how roughly KRW 43 trillion of operating losses accumulated between 2021 and 2023. If you believe the thesis, the real questions become sizing and overlap rather than timing. Walnut is not an investment adviser and this is not a recommendation.

Nobody can answer that for you, and the honest version of the question is narrower: has anything changed in the reason you bought it? The bear case on this page is the place to check. The controlling shareholder and the price regulator are the same government, and Korea has repeatedly capped the quarterly fuel cost adjustment when household bills got politically difficult, which is how roughly KRW 43 trillion of operating losses accumulated between 2021 and 2023. If that risk is what you were worried about and it is now playing out, that is a real signal. If the price simply fell while the thesis held, that is a different situation entirely. Walnut is not an investment adviser.

Tariffs that cover cost, and the reform behind them. The swing from a KRW 4.2 trillion operating loss in 2023 to roughly KRW 14 trillion of operating profit in 2025 came mostly from rates catching up to fuel, not from volume or efficiency.

The controlling shareholder and the price regulator are the same government, and Korea has repeatedly capped the quarterly fuel cost adjustment when household bills got politically difficult, which is how roughly KRW 43 trillion of operating losses accumulated between 2021 and 2023. That squeeze has already begun to return, with first-half 2026 fuel expense up 8.8% to KRW 10.1 trillion, operating profit down 16.6%, and management flagging that fuel may stay elevated into the second half because international prices reach domestic wholesale rates with a lag. Volume offers no cushion either, since industrial demand at roughly 51% of sales fell 2.2% year over year. Against KRW 49 trillion of total equity the company carries KRW 133 trillion of borrowings, so one bad tariff year compounds fast. US holders take on two further layers: only about 25.5 million ADSs are outstanding, some 2% of the shares, and every return is translated back through a won that has weakened materially against the dollar.

South Korea's state-controlled electricity monopoly, which owns the national grid, buys nearly all the country's power, and resells it at government-approved rates.

Decide that in advance, because it is far harder to think clearly once a position is moving against you. The concrete tripwires here: the driver behind the bull case (Tariffs that cover cost, and the reform behind them) stalling in the reported numbers rather than in the narrative, the risk above (the controlling shareholder and the price regulator are the same government, and Korea has repeatedly capped the quarterly fuel cost adjustment when household bills got politically difficult, which is how roughly KRW 43 trillion of operating losses accumulated between 2021 and 2023) turning from a possibility into a reported fact, or the position growing large enough that a bad outcome would matter to your whole portfolio regardless of who is right.

KEPCO owns and operates South Korea's transmission and distribution grid and acts as the single buyer in the country's cost-based power pool. It purchases roughly 545,000 gigawatt hours a year through the Korea Power Exchange, from its own generation subsidiaries and from independent producers, then sells that power to end customers at government-approved rates. Generation itself is held in six main subsidiaries, led by Korea Hydro & Nuclear Power.

One KEP American depositary share represents one-half of one Korea Electric Power common share, with Citibank as depositary. The NYSE quote therefore runs at roughly half the Seoul price, and per-ADS earnings and dividends are half the per-share figures. About 25.5 million ADSs were outstanding at the end of 2025, some 2% of the company's shares, so the US listing is a thin slice of a KOSPI-listed company.

Korean won, under IFRS, in a 20-F filed with the SEC rather than a 10-K, because KEPCO is a foreign private issuer. Trailing twelve-month revenue of about KRW 97.6 trillion converts to roughly $69 billion at about 1,415 won to the dollar, and that conversion moves whenever the exchange rate does. A US holder's return therefore blends the stock's performance in won with the won's performance against the dollar.
