Electric Fuel and Purchased Power - Expenses incurred for electric fuel and purchased power are impacted by fluctuations in market prices of natural gas and coal, as well as seasonality. These incurred expenses are generally recovered through various regulatory recovery mechanisms. As a result, changes in these expenses are largely offset in operating revenues and have minimal earnings impact.
Electric fuel and purchased power expenses decreased $150 million year-to-date. The decrease is primarily due to decreased regional commodity prices.
Non-Fuel Operating Expense and Other Items
Depreciation and Amortization - Depreciation and amortization increased $27 million year-to-date, largely due to system investment.
Interest Charges - Interest charges increased $25 million year-to-date, largely due to higher debt levels.
AFUDC, Equity and Debt - AFUDC increased $34 million year-to-date, largely due to system investment.

Public Utility Regulation and Other
|
The FERC and state and local regulatory commissions regulate SPS. SPS is subject to rate regulation by state utility regulatory agencies, which have jurisdiction with respect to the rates of electric distribution companies in New Mexico and Texas.
Rates are designed to recover plant investment, operating costs and an allowed return on investment. SPS requests changes in utility rates through commission filings. Changes in operating costs can affect SPS' financial results, depending on the timing of rate cases and implementation of final rates. Other factors affecting rate filings are new investments, sales, conservation and demand side management efforts and the cost of capital.
In addition, the regulatory commissions authorize the ROE, capital structure and depreciation rates in rate proceedings. Decisions by these regulators can significantly impact SPS' results of operations and credit quality.
Except to the extent noted below, the circumstances set forth in Public Utility Regulation included in Item 7 of SPS' Annual Report on Form 10-K for the year ended Dec. 31, 2025, appropriately represent, in all material respects, the current status of public utility regulation and are incorporated herein by reference.
Pending and Recently Concluded Regulatory Proceedings
2025 New Mexico Electric Rate Case - In November 2025, SPS filed an electric rate case with the NMPRC. As updated in March 2026, SPS requested a revenue increase of $168 million (16.0%). The request was based on a future test year period ending Nov. 30, 2027, a ROE of 10.5%, an equity ratio of 56% and retail rate base of $3.9 billion.
In June 2026, SPS, New Mexico Department of Justice, New Mexico Large Customer Group and various other parties filed a comprehensive non-unanimous stipulation. NMPRC Staff opposes certain components of the stipulation.
Terms of the stipulation include:
•Base rate revenue increase of $90 million (7.7% total, or an annual average of 2.4% since the last rate case), based on the filed future test year.
•ROE of 9.5%.
•Equity ratio of 54.70%.
A hearing on the non-unanimous stipulation took place in July 2026. On Oct. 23, 2026, SPS received the Hearing Examiners' Report, which recommended NMPRC approval with certain minor modifications. Any exceptions are required to be filed by Nov. 2, 2026. An NMPRC decision is anticipated in the fourth quarter of 2026, with implementation of rates expected in December 2026.
SPS 2023 Integrated Resource Plan - In October 2023, SPS filed its IRP with the NMPRC, which supports projected load growth and increasing reliability requirements, and secures replacement energy and capacity for retiring resources.
In July 2024, SPS issued a RFP, seeking approximately 3,200 MW of accredited capacity by 2030. In July 2025, the portfolio selection report was publicly filed with the NMPRC. SPS filed for approval of approximately 2,800 MW of accredited resources, including approximately 4,000 MW of nameplate capacity company owned resources and approximately 500 MW of nameplate capacity PPAs. SPS has received NMPRC approval of the CCN filings for the assets. In October 2026, the PUCT approved the self build portfolio with the exception of the Plant X battery storage project. The approval includes performance and cost cap guarantees. SPS will be seeking rehearing on this decision.
In October 2025, SPS issued a RFP to solicit 870 MW of accredited capacity through 2032 (approximately 1,500 MW to 3,000 MW nameplate capacity, or more depending on resource mix), with additional resources to be evaluated to meet the New Mexico RPS compliance need. The portfolio selection report was publicly filed with the NMPRC in July 2026, with a preferred portfolio that contains approximately 2,600 MW of nameplate capacity company owned resources and approximately 1,300 MW of nameplate capacity PPAs. Project CCNs are expected to be filed in early 2027.
SPS 2026 IRP - In October 2026, SPS filed its 2026 IRP with the NMPRC, which demonstrates projected load growth and shows energy and capacity resource portfolio needs under three different load forecast scenarios. Based on these forecast scenarios and the progress of existing resource acquisition processes, SPS' initial IRP modeling identified resource needs of approximately 2,000 MW of incremental accredited capacity by 2034. Following NMPRC action on the IRP, SPS expects to issue a competitive all-source solicitation for new generation in mid-2027 with project selection expected in early 2028.

Tariffs, Trade Complaints and Federal Actions
Several trade cases related to anti-dumping and countervailing duty investigations are ongoing and we continue to monitor the potential impacts of these cases.
Executive orders have been issued imposing new global and country-specific tariffs on many imports, which may impact our procurement and development activities. Additionally, executive orders and actions from government agencies may impact the permitting of wind and solar facilities and the retirement of coal facilities.
SPS continues to assess the impacts of these tariffs, executive orders, trade complaints and federal policies on its business, including company owned projects and PPAs. SPS may seek regulatory relief, if required, in its jurisdictions.
