## Summary

Southern Company (SO) reported ~$23.5B revenue in FY2024. Large regulated electric and natural gas utility serving 9M customers across Georgia, Alabama, and Mississippi. HQ: Atlanta.

## Company Overview

The Southern Company is one of America's largest regulated electric and natural gas utilities, serving approximately 9 million electric and gas customers across Georgia, Alabama, Mississippi, and Illinois through its principal subsidiaries: Georgia Power, Alabama Power, Mississippi Power, and Southern Natural Gas. Founded in 1945, Southern Company has grown into a $23+ billion revenue utility holding company with one of the largest service territories in the Southeast, a region experiencing sustained population and economic growth.

Southern Company reported approximately $23.5 billion in revenue in FY2024, reflecting the scale of its regulated utility operations and its pivotal role in the energy transition. The company's headline-making project has been Plant Vogtle in Georgia — the first new nuclear power plant licensed and built in the United States in three decades. Unit 3 achieved commercial operation in July 2023 and Unit 4 in April 2024, adding approximately 2.4 gigawatts of carbon-free baseload generation after years of delays and billions in cost overruns totaling ~$35 billion for both units. Despite the painful construction experience, the completed nuclear plant provides 60 years of clean, reliable baseload power.

Southern Company's regulated model provides predictable earnings growth tied to rate base expansion — as the company invests in new generation, transmission, and distribution infrastructure, regulators allow it to earn a return on those investments through customer rates. Data center demand in Georgia (one of the top U.S. data center markets) is driving unprecedented load growth that requires accelerated grid investment. The company is also advancing hydrogen fuel cell and carbon capture pilot projects as part of its net-zero by 2050 commitment.
