As disclosed in Avista Corporation's (the Company) Form 10-Q for the quarter ended September 30, 2023, in September 2020 a severe windstorm in eastern Washington and northern Idaho resulted in the start of the Babb Road fire. Eleven lawsuits have been filed naming the Company as a defendant in connection with the fire. Asplundh Tree Company and CNUC Utility Consulting, which both perform vegetation management services as independent contractors to the Company, are also named as defendants in each of the lawsuits. The lawsuits include six subrogation actions filed by insurance companies seeking to recover approximately $23 million purportedly paid to insureds to date; four actions on behalf of individual plaintiffs seeking unspecified damages; and a class action lawsuit seeking unspecified damages. All proceedings were consolidated for discovery and pre-trial proceedings under the lead action Blakeley et al. v. Avista Corporation et al. All proceedings variously asserted causes of action for negligence, private nuisance, trespass and inverse condemnation (a theory of strict liability). On November 29, 2023, all parties to the Blakeley et al. v. Avista Corporation et. al. consolidated cases agreed to a stipulated order, which was presented to and entered by the Superior Court of Spokane County, Washington on December 1, 2023. The order consolidates the Babb Road fire cases for trial (in addition to discovery and pre-trial proceedings) and bifurcates the trial into liability and damages phases, such that the initial trial in the case will focus solely on whether the defendants are legally responsible for the Babb Road Fire. In addition, the order memorializes the plaintiffs' agreement to voluntarily dismiss all claims asserting inverse condemnation as a theory of liability without prejudice. The parties agreed to a preliminary mediation no later than 60 days prior to the liability trial, and, if the jury returns a verdict in the plaintiffs' favor in the liability trial, a second mediation within 90 days following the verdict focusing on damages. Finally, the plaintiffs agreed to complete a damages questionnaire identifying all claimed damages being sought in connection with the litigation. The Company will vigorously defend itself in the legal proceedings; however at this time the Company is unable to predict the likelihood of an adverse outcome or estimate a range of potential loss in the event of such an outcome.   SIGNATURES Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.       Avista Corporation       (Registrant)         Date: December 1, 2023 By: /s/ Gregory C.
