Southern Company faces headwinds from the potential for increased regulation of greenhouse gas emissions and other environmental matters. The company's operations are subject to extensive federal, state, and local environmental laws and regulations, including those related to air emissions, water discharges, and waste management. Compliance with these regulations could require significant capital expenditures and increase operating costs. The company also faces risks related to the availability and cost of fuel, particularly natural gas, which can impact its fuel cost recovery mechanisms.
Southern Company's growth plan is subject to execution risks related to the construction and operation of large capital projects, including nuclear, solar, and natural gas generation facilities. The company's Vogtle Units 3 and 4 nuclear expansion project, which was completed in 2024, involved significant cost overruns and construction delays. The company also faces risks related to the integration of acquired businesses and the realization of expected synergies. Regulatory approval for rate recovery of capital investments is a key constraint on the company's ability to earn its authorized return on equity.

The company's capital expenditure plan of approximately $14.0 billion 33 for 2026 through 2028 is subject to execution risks, including construction delays, cost overruns, and the ability to recover investments through regulated rates.
