Section 8 - Other Events

Item 8.01 Other Events.

On June 9, 2025, Avista Corporation (Avista Corp. or the Company) and all other parties to the Company's electric and natural gas general rate cases in Idaho filed a settlement agreement with the Idaho Public Utilities Commission (IPUC) for its consideration. If approved, new rates would take effect on September 1, 2025 and September 1, 2026.

The settlement includes agreement on electric and natural gas revenue requirement increases for both years of the multi-year rate plan. The recommendation to the IPUC by its Staff or other parties to approve the multiparty settlement is not binding on the IPUC itself.

If approved, the settlement agreement is designed to increase annual base electric revenues by $19.5 million (or 6.3 percent), effective September 1, 2025, and $14.7 million (or 4.5 percent), effective September 1, 2026. The agreement is also designed to increase annual base natural gas revenues by $4.6 million (or 9.2 percent), effective September 1, 2025, and decrease annual base natural gas revenues by $0.2 million (or 0.4 percent), effective September 1, 2026.

The settlement contemplates a return on equity of 9.6 percent, based on a common equity ratio of 50 percent, and a rate of return on rate base of 7.28 percent.

For base electric revenues, the Company originally requested an increase of $43.0 million (or 14.0 percent), effective September 1, 2025, and $17.7 million (or 5.0 percent), effective September 1, 2026. For base natural gas revenues, the Company originally requested an increase of $8.8 million (or 17.7 percent), effective September 1, 2025, and $1.0 million (or 1.7 percent), effective September 1, 2026. The lower base revenue agreed to by the parties is mainly due to a lower return on equity than the Company requested, as well as longer recovery periods for amortizations, a reduction in power supply expense versus filed, and a change in the law affecting the way property taxes are calculated and collected from customers.
