**Item 7.01 Regulation FD Disclosure.**

Tri-State Generation and Transmission Association, Inc. ("Tri-State") has a contract termination payment methodology tariff on file with the Federal Energy Regulatory Commission as Rate Schedule No. 281 that provides a process should a utility member elect to withdraw from membership in Tri-State and terminate its wholesale electric service contract. Certain elements of Rate Schedule No. 281 remain subject to ongoing proceedings at the United States Court of Appeals for the Tenth Circuit and the D.C Circuit.

On March 27, 2026, Wheat Belt Public Power District ("Wheat Belt"), which is electrically served in both the Eastern and Western Interconnections, provided a non-conditional two-year notice of intent to withdraw from membership in Tri-State, with an April 1, 2028, withdrawal effective date, pursuant to Rate Schedule No. 281. Tri-State cannot predict if Wheat Belt will withdraw its membership and terminate its wholesale electric service contract. Wheat Belt comprised 1.35 percent and 0.89 percent of Tri-State's utility member revenue and operating revenue, respectively, for the year ended December 31, 2025.

On March 30, 2026, Tri-State issued a press statement related to Wheat Belt's notice of intent to withdraw. A copy of the press statement is attached to this report as Exhibit 99.1.

## Exhibit 99.1

**EXHIBIT 99.1**

**Wheat Belt Public Power District gives notice to withdraw from Tri-State membership** 

(Westminster, Colo., March 30, 2026) Wheat Belt Public Power District on Mar. 27, 2026, provided not-for-profit wholesale power supply cooperative Tri-State Generation and Transmission Association a non-conditional notice to withdraw from membership in Tri-State, including an early termination of its Wholesale Electric Service Contract (WESC).

The notice includes an April 1, 2028, withdrawal effective date, in accordance with the terms of Tri-State's Contract Termination Payment (CTP) tariff.

Wheat Belt PPD, based in Sidney, Neb., represents 1.35% of Tri-State's utility member revenue and 0.89% of operating revenue for the year ended Dec. 31, 2025.

The CTP tariff on file with the Federal Energy Regulatory Commission (FERC) provides a process should a utility member elect to withdraw from Tri-State membership and terminate its WESC early. This includes requirements for a two-year notice and the payment of a CTP to Tri-State. Each CTP amount will be determined consistent with the FERC tariff and orders, certain elements of which also remain subject to ongoing appeals.

**About Tri-State** 

Tri-State is a wholesale power supply cooperative, operating on a not-for-profit basis, with electric distribution cooperatives and public power district members in four states, including Colorado, Nebraska, New Mexico and Wyoming. Together with its members, Tri-State delivers reliable, affordable and responsible power and energy services to nearly a million electricity consumers across roughly 200,000 square miles of the West.
