Outline of Consolidated Financial Results for FY2026 3Q



Operating revenue (Decrease)

Operating revenue decreased by 28.7 billion yen year-on-year to 617.7 billion yen mainly due to a decrease in the fuel cost adjustments associated with the decline in fuel prices and other factors.

Ordinary income

(Increased)

Ordinary income rose by 11.1 billion yen year-on-year, reaching a total of 67.9 billion yen. This increase was primarily attributable to higher time difference gains under the fuel cost adjustment system, which resulted mainly from a decline in fuel prices, as well as lower fuel costs due to an increase in hydroelectric power generation, while the labor costs, commodity prices, and interest rates increased.

Profit attributable to owners of parent (Decrease)

Profit attributable to owners of parent was 48.8 billion yen, a decrease of 5.8 billion yen from the same period of the previous fiscal year, reflecting the decrease in gains on the nuclear fuel sale posted as extraordinary income, despite an increase in ordinary income.

Summary of Forecasts of Consolidated Financial Performance in FY2026



Electricity Sales

The estimate for retail electricity sales is not changed from the October announcement. Electricity sales to other utilities are expected to increase mainly due to an increase in direct wholesales. Accordingly, the total of retail electricity sales and electricity sales to other utilities is forecast to be around 34.6 billion kWh, an increase of 200 million kWh in contrast with the forecast announced in October 2025.

Operating revenue

We forecast an operating revenue of approximately 867.0 billion yen, a decrease of 1.0 billion yen, in contrast with the projections announced in October, chiefly due to a decline in fuel cost adjustments in tandem with a drop in fuel prices.

Ordinary Income

Although time difference gain under the fuel cost adjustment system has expanded due to lower fuel prices and other factors, we forecast ordinary income to be around 43.0 billion yen, the same level projected in the October announcement, mainly due to costs to restore power transmission and distribution facilities damaged by the December low-pressure system.

Profit attributable to owners of parent

Profit attributable to owners of parent is expected to be approximately 28.0 billion yen, unchanged from the projection announced in October.

・Retail electricity sales volume totaled 15,525 million kWh, a decrease of 2.9% year on year, primarily due to low wholesale electricity market prices and fuel prices as well as a highly competitive business environment.

・Electricity sales to other utilities totaled 9,142 million kWh, an increase of 15.2% year-over-year, mainly due to a rise

in sales volume owing to an increase in the purchase of renewable energy.

・Sales in the HEPCO segment totaled 527.3 billion yen, a decrease of

39.5 billion yen year-on-year, chiefly due to a decline in fuel cost adjustments in tandem with a drop in fuel prices and other factors.

Ordinary income for the segment rose by 6.6 billion yen year-on-year, reaching a total of 57.4 billion yen. This increase was primarily attributed to higher time difference gains under the fuel cost adjustment system, which resulted mainly from a decline in fuel prices, as well as lower fuel costs due to an increase in hydroelectric power generation, while labor costs, commodity prices, and interest rates increased.

・Sales in the Hokkaido Electric Power Network segment totaled 230.9 billion yen, an increase of 1.8 billion yen year-on-year mainly due to higher wheeling service tariff revenue as a result of the revision of the wheeling service fees and the increased area demand during the hot summer.

Ordinary income for the segment totaled 2.8 billion yen, an increase of

2.7 billion yen year-on-year, chiefly due to increased sales and overall improvements in management efficiency, while there were increases in labor costs, commodity prices, and interest rates.

・Other sales amounted to 112.1 billion yen, an increase of 8.5 billion yen in comparison with the same period of the previous fiscal year. Meanwhile, segment ordinary income amounted to 10.7 billion yen, an increase of

2.8 billion yen from the same period of the previous year, mainly reflecting increased operations of hydroelectric power plants at subsidiaries and increased sales in the construction business.
