Excess Liability Insurance Deferral - In early 2025, SPS filed requests with the NMPRC and PUCT for deferred accounting treatment for incremental excess liability insurance expense incurred as a result of the October 2024 policy renewal, estimated at approximately $30 million across the two jurisdictions. In October 2025, the NMPRC approved the request, resulting in a deferral of approximately $15 million of incremental excess liability insurance costs in 2025 and $7 million in the six months ended June 30, 2026. In January 2026, SPS, PUCT Staff and other intervenors filed a black box settlement expected to result in annual deferrals of approximately $8 million in 2026 and 2027. A PUCT decision is forthcoming.

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.
Xcel Energy continues to assess the impacts of these tariffs, executive orders, trade complaints and federal policies on its business, including company owned projects and PPAs. Xcel Energy may seek regulatory relief, if required, in its jurisdictions.
Continued and/or further policy actions or other restrictions, disruptions in imports from key suppliers, or any new trade complaint could impact viability, timelines and costs of various projects and PPAs.
Large Load/Data Center Tariffs
In several of our jurisdictions, we have proposed tariffs applicable to large load customers. These tariffs are designed to allow us to serve these new customers and support local economic development while protecting existing customers from bearing the incremental costs to serve these loads.
While the details of these tariffs vary by jurisdiction, they generally include provisions to ensure data center customers pay the incremental costs to serve them, minimum demand or revenue requirements, termination or exit fees and customer security provisions. These tariffs and contracts are subject to approval by state regulatory commissions. The status of the filings in each jurisdiction is as follows.
NSP-Minnesota -The tariff, which was approved by the MPUC in June 2026, is mandatory for new loads over 100 MW and includes an incremental cost test, minimum initial term of 15 years, minimum bill provisions, termination and exit fees, and credit requirements.
NSP-Wisconsin - NSP-Wisconsin filed a proposed tariff in the second quarter of 2026, which would be mandatory for new loads over 100 MW and requires the customer pay for generation and other infrastructure costs needed to serve the load, if approved as filed. The proposed tariff also includes a minimum initial term of 15 years, minimum bill provisions, termination and exit fees, and credit requirements. A PSCW decision is expected in early 2027.
PSCo - The proposed tariff, filed in the second quarter of 2026, would be mandatory for new loads over 50 MW and requires the customer pay for generation and other infrastructure costs needed to serve the load. The proposed tariff also includes a minimum initial term of 15 years, minimum bill provisions, termination and exit fees, and credit requirements. A CPUC decision is expected in late 2026 or early 2027.
Similar large load tariff requests are expected to be filed in New Mexico and Texas by the end of 2026.

Critical Accounting Policies and Estimates
|
Preparation of the consolidated financial statements requires the application of accounting rules and guidance, as well as the use of estimates. Application of these policies involves judgments regarding future events, including the likelihood of success of particular projects, legal and regulatory challenges and anticipated recovery of costs. These judgments could materially impact the consolidated financial statements, based on varying assumptions. The financial and operating environment also may have a significant effect on the operation of the business and results reported. Items considered critical are included within the Xcel Energy Inc. Annual Report on Form 10-K for the year ended Dec. 31, 2025.
Throughout 2025 and 2026, the EPA has announced various regulatory actions addressing a wide range of environmental regulations. Xcel Energy will continue to monitor proposed rules as they move toward final action. Additionally, any other amendments and changes to rules will be evaluated as proposed by the EPA.
Clean Air Act
Power Plant Greenhouse Gas Regulations - In April 2024, the EPA published final rules addressing control of CO2 emissions from the power sector. The rules regulate new natural gas generating units and emission guidelines for existing coal and certain natural gas generation.
Based on current estimates and assumptions, Xcel Energy has determined that due to scheduled plant retirements, there is minimal financial or operational impact associated with these requirements and believes that the cost of these initiatives or replacement generation would be recoverable through rates based on prior state commission practices.
In June 2025, the EPA proposed to repeal these and all other GHG emissions standards for the power sector. In the alternative, the EPA proposed to repeal a narrower subset of the 2024 regulations.
Endangerment Finding - In February 2026, the EPA issued a final rule repealing the 2009 Endangerment Finding and associated regulations addressing GHG emissions from new motor vehicles and engines under the Clean Air Act. Xcel Energy will monitor any additional proposed rules and evaluate the impacts of any final rule on the utility sector.
Emerging Contaminants of Concern
PFAS are man-made chemicals that are widely used in consumer products and can persist and bio-accumulate in the environment. Xcel Energy does not manufacture PFAS, but because PFAS are so ubiquitous in products and the environment, it may impact our operations.
In June 2024, the EPA finalized a rule that designated certain PFAS as hazardous substances under CERCLA. In July 2024, the EPA finalized another rule that set enforceable drinking water standards for certain PFAS.
Potential costs for these rules and any additional proposed regulations related to PFAS are uncertain and will be determined on a site specific basis where applicable. If costs are incurred, Xcel Energy believes the costs would be recoverable through rates based on prior state commission practices.
