Adjusted earnings drivers for the full year 2025, as compared with 2024, were higher utility revenues, partially offset by higher non-fuel operations and maintenance expenses, depreciation and amortization, and interest expense.
Fourth-quarter 2025 operating revenues were $7.0 billion, compared with $6.3 billion for the fourth quarter of 2024, an increase of 10.1%. Operating revenues for the full year 2025 were $29.6 billion, compared with $26.7 billion in 2024, an increase of 10.6%.

performance of counterparties under ongoing renewable energy partnerships and development agreements; state and federal rate regulations and the impact of pending and future rate cases and negotiations, including rate actions relating to return on equity, equity ratios, additional generating capacity and transmission facilities, extension of retirement dates for fossil fuel plants, and fuel and other cost recovery mechanisms; the ability to successfully operate Southern Company’s electric utilities’ generation, transmission, distribution, and battery energy storage facilities, as applicable, and Southern Company Gas’ natural gas distribution and storage facilities and the successful performance of necessary corporate functions; the inherent risks involved in operating nuclear generating facilities; the inherent risks involved in generation, transmission, and distribution of electricity and transportation and storage of natural gas, including accidents, explosions, fires, mechanical problems, discharges or releases of toxic or hazardous substances or gases, and other environmental risks;

Further charges related to the remeasuring of deferred tax assets may occur; however, the amount and timing are uncertain. Earnings for the three and twelve months ended December 31, 2025 and 2024 also include charges (net of salvage proceeds), associated legal expenses (net of insurance recoveries), and tax impacts related to Mississippi Power Company's integrated coal gasification combined cycle facility project in Kemper County, Mississippi.
