Here are a few analogies to describe MGE Energy (MGEE):

• Like Consolidated Edison (Con Edison), but serving parts of Wisconsin with electricity and natural gas instead of New York.
• Like your local Comcast or Verizon Fios, but instead of delivering internet and TV, it delivers electricity and natural gas to homes and businesses in its service area.
• Like Waste Management (WM), but instead of managing waste, it manages the delivery of essential electricity and natural gas services to homes and businesses.

• Electric Utility Services: Provides electricity generation, transmission, and distribution to residential, commercial, and industrial customers.
• Natural Gas Utility Services: Distributes and sells natural gas to residential, commercial, and industrial customers.

MGE Energy (symbol: MGEE) is a utility holding company whose primary subsidiary, Madison Gas and Electric (MGE), provides electricity and natural gas services in south-central Wisconsin. As a utility, it sells directly to end-users within its defined service territory rather than primarily to a few other companies as major corporate customers.

MGE Energy's customer base is categorized as follows:

• Residential Customers: This category includes individual households and residences that use electricity and/or natural gas for heating, cooling, lighting, and appliances. These are individuals who live in single-family homes, apartments, and other residential dwellings.
• Commercial Customers: This segment comprises a wide range of businesses, organizations, and institutions within MGE's service area. This typically includes retail stores, offices, restaurants, schools, hospitals, small to medium-sized businesses, and government buildings that consume energy for their operations.
• Industrial Customers: This category consists of larger manufacturing facilities, industrial plants, and other major energy-intensive businesses that require substantial amounts of electricity and/or natural gas for their production processes.

The increasing adoption of decentralized energy generation and distributed energy resources (DERs), such as rooftop solar panels and battery storage systems, by residential and commercial customers. This trend has the potential to reduce reliance on MGE Energy's centralized generation and grid infrastructure, leading to lower demand for grid-supplied electricity and gas, impacting revenue streams, and challenging the traditional utility business model centered on large-scale power production and delivery.

For MGE Energy (symbol: MGEE), the addressable markets for their main products and services are defined by their regulated utility service territory in south-central and western Wisconsin.

MGE Energy (MGEE) is expected to drive future revenue growth over the next 2-3 years through several key initiatives and factors:

1. Strategic Investments in Renewable Energy and Battery Storage: MGE Energy is actively investing in new renewable generation projects, including solar and battery storage facilities. Projects such as the Darien Solar Project and the Paris Battery Energy Storage System (BESS) became operational in 2025, contributing to asset growth and increased electric earnings. The company aims for significant carbon reduction, aligning with customer demand and regulatory trends favoring clean energy, which necessitates ongoing capital deployment in these areas.
2. Rate Base Investment Growth and Regulatory-Approved Rate Increases: Revenue growth is significantly influenced by rate base investment growth. MGE Energy has received regulatory approval for rate increases, including a 2.63% increase for electric and 1.32% for gas in 2025. Furthermore, there are pending regulatory approvals for proposed rate increases for 2026 (4.89% electric and 2.33% gas) and 2027 (4.33% electric and 2.16% gas), which are expected to directly impact future revenues.
3. Grid Modernization and Technological Innovation: The company is committed to technological innovation, including significant investments in grid modernization and smart grid solutions. These initiatives enhance service delivery, customer satisfaction, and operational efficiency. MGE Energy also makes venture capital investments in early-stage companies focused on smart technologies, distributed energy resources, and electrification, which contribute to non-utility earnings.
4. Customer Growth and Increased Sales Volumes: MGE Energy serves a substantial customer base, and future load growth is a factor influencing its financial results. Dane County, within MGE Energy's service territory, is projected for strong population growth, which is expected to support the company's capital spending outlook and lead to increased electric and gas sales volumes.
