Section 1 - Registrant's Business and Operations

Item 1.01 Entry into a Material Definitive Agreement.

See description of Avista Corp.’s issuance of $120.0 million of 6.18 percent first mortgage bonds due in 2055 under Item 2.03.

Section 2 - Financial Information

Item 2.03 Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

On July 23, 2025, Avista Corporation (Avista Corp. or the Company) issued and sold $120.0 million of 6.18 percent first mortgage bonds due in 2055 pursuant to a bond purchase agreement with institutional investors in the private placement market. The new first mortgage bonds were issued under and in accordance with the Mortgage and Deed of Trust, dated as of June 1, 1939, from the Company to Citibank, N.A., trustee, as amended and supplemented by various supplemental indentures and other instruments, including the Sixty-ninth Supplemental Indenture, dated as of July 1, 2025 (the “Mortgage”). The new bonds are subject to redemption prior to maturity, at the option of the Company, at a redemption price equal to the principal amount thereof plus a “make-whole” premium and plus accrued interest. The Mortgage constitutes a lien on substantially all the property of the Company (other than excepted property).

In connection with the pricing of the first mortgage bonds in July 2025, the Company cash settled one interest rate swap derivative (notional aggregate amount of $10.0 million) and received a net amount of $1.1 million, which will be amortized as a component of interest expense over the life of the debt.

The net proceeds from the sale of the new bonds will be used to repay borrowings outstanding under the Company's committed line of credit made for the construction or improvement of utility facilities or to reimburse the treasury for moneys expended for this purpose.

The bonds have not been, and will not be, registered under the Securities Act of 1933 or any state securities laws and may not be offered or sold in the United States absent registration or an applicable exemption from registration requirements.

The Mortgage, as previously amended and supplemented, is referred to in and filed as Exhibits 4.1 through 4.69 to the Company’s Annual Report on Form 10-K for the year 2024.
