Item 8.01. Other Events

In November 2022, Southwestern Public Service Company (SPS), a New Mexico corporation, and a wholly owned subsidiary of Xcel Energy, Inc., filed an electric rate case with the New Mexico Public Regulation Commission (NMPRC) seeking a revenue increase of $78 million, or 10%. In May 2023, SPS revised its request to $75 million. The request is based on a future test year ending June 30, 2024, a return on equity (ROE) of 10.75%, an equity ratio of 54.7%, rate base of $2.4 billion and further acceleration of the Tolk coal plant depreciation life from 2032 to 2028.

On May 18, 2023, SPS, NMPRC staff, and various parties filed a contested comprehensive stipulation. Two intervenors, environmental advocacy organizations, oppose the stipulation.

 Terms of the contested stipulation include: •Base rate revenue increase of $33 million, based on the filed future test year. •ROE of 9.5%. •Equity ratio of 54.7%. •Acceleration of Tolk coal plant depreciation life to 2028, as requested in SPS' filing. 

Hearings are scheduled for the second quarter of 2023. A NMPRC decision is anticipated in the fourth quarter of 2023.

Xcel Energy reaffirms its 2023 GAAP and ongoing earnings guidance of $3.30 to $3.40 per share, which is based on several key assumptions, including constructive regulatory outcomes.
