**Item 2.04&nbsp;&nbsp;&nbsp;&nbsp;Triggering Events That Accelerate or Increase a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement.**

On January 9, 2026, Tri-State Generation and Transmission Association, Inc. ("Tri-State") received internal notification that certain state unemployment taxes (collectively, the "Taxes") were not timely paid. The total amount for the Taxes, inclusive of interest and penalties, was less than $1 million. In some instances, the failure to timely pay the Taxes resulted in tax liens. Tri-State has since paid the Taxes, interest and penalties in all states in which the Taxes were owed, thereby satisfying associated tax liens.

Tri-State's various lending arrangements include covenants related to timely payment of taxes and avoidance of unpermitted liens. Certain of these agreements either identify an unpermitted lien as an event of default or contain cross default provisions, or both, with no specified cure period. Similar tax and unpermitted lien covenants are contained in Tri-State's Master First Mortgage Indenture, Deed of Trust and Security Agreement, effective as of December 15, 1999, between Tri-State and U.S. Bank Trust Company, National Association, as successor trustee, as amended (the "Master Indenture"). Tri-State determined that the nonpayment of the Taxes and related imposition of tax liens constituted a technical default under the Master Indenture, with an initial 30-day cure period prior to an event of default.

The now cured technical default under various lending arrangements would have permitted the applicable lenders or administrative agents to declare an acceleration of the financial obligations under certain lending arrangements, which could have resulted in Tri-State being responsible to repay approximately $950 million. During the initial cure period, the trustee of the Master Indenture was not permitted to accelerate the debt secured under the Master Indenture.

Because all the Taxes have been paid and all tax liens satisfied, Tri-State considers the default under the Master Indenture and related defaults under other lending arrangements to be cured and no longer continuing, and the applicable lenders or administrative agents have no continued right to accelerate Tri-State's debt under the terms of the applicable lending arrangements. Tri-State is refreshing its systems and protocols to prevent a recurrence of this or similar issues.

**Item 5.02&nbsp;&nbsp;&nbsp;&nbsp;Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.**

On January 13, 2026, Tri-State received notification from Julie Kilty, the Secretary of Tri-State and the director representing Wyrulec Company on Tri-State's Board of Directors, that she was resigning from her position as Secretary and a director on Tri-State's Board of Directors effective immediately. To Tri-State's knowledge, Ms. Kilty's resignation is not due to any disagreement with Tri-State.
