MGE Energy Reports Third-Quarter 2025 Earnings

Madison, Wis., Nov. 5, 2025—MGE Energy, Inc. (Nasdaq: MGEE), today reported financial results for the third quarter of 2025.

MGE Energy's GAAP (Generally Accepted Accounting Principles) earnings for the third quarter of 2025 were $44.5 million, or $1.22 per share, compared to $40.9 million, or $1.13 per share, for the same period in the prior year. Rate base investment growth and non-utility investment gains drove our third-quarter results.

Electric segment earnings were $1.3 million higher in the third quarter of 2025, a result of strategic capital investments that grew rate base. This growth was largely driven by the successful deployment of key renewable energy projects. The Darien Solar Project in Rock and Walworth counties became operational in March 2025, followed by the Paris Battery Energy Storage System (BESS) in June 2025. MGE owns 25 MW of solar capacity from the Darien Solar Project and 11 MW of battery capacity from the Paris BESS.

Gas net income exhibited steady performance, with minimal variation compared to the third quarter of 2024.

Investment gains of approximately $2.2 million from venture capital funds drove higher non-utility earnings for the third quarter of 2025. These venture capital investments support early-stage companies working to advance smart technologies, the customer experience, distributed energy resources, electrification, cybersecurity, and other priorities for utility companies such as greater sustainability.
