Southern Company finds fresh momentum in Southeast power demand

Revenue growth puts demand at the centre of Southern Company’s result

Large customers and warmer weather helped Southern Company (NYSE:SO) produce a notably stronger third quarter, with net income attributable to the company rising 19.6% to US$2.046 billion, or US$1.77 per share, from US$1.711 billion, or US$1.55 per share, a year earlier. Operating revenue rose 13% to US$8.843 billion.

The demand signal was particularly visible in electricity volumes. Total retail sales increased 7.7% in the quarter, while commercial sales rose 10.1% and industrial sales gained 2.5%. The company said higher usage, customer growth and growing revenue from large commercial and industrial customers supported earnings, alongside warmer weather. Total regulated utility customers reached 8.996 million at the end of September, up 0.7% from a year earlier.

Adjusted earnings show stronger underlying quarter

On Southern Company’s non-GAAP measure, which excludes specified items, third-quarter net income increased to US$2.242 billion from US$1.766 billion. Adjusted basic earnings per share rose to US$1.94 from US$1.60, despite the average share count increasing to 1.157 billion from 1.102 billion.

The nine-month numbers tell the same broad story. Reported earnings reached US$4.577 billion, up from US$3.925 billion, while adjusted earnings rose to US$5.017 billion from US$4.135 billion. Nine-month revenue was US$24.218 billion, 7.3% higher than in the corresponding period of 2025.

Georgia Power leads utility performance as costs remain visible

Georgia Power was the largest contributor to the quarter’s improvement among the disclosed operating businesses. Its net income available to common rose 22% to US$1.523 billion, while Alabama Power’s increased 12.4% to US$661 million. Southern Power’s net income climbed to US$52 million from US$3 million, although its nine-month result fell to US$30 million from US$141 million.

The reported figures were reduced by several items that Southern Company excludes from its adjusted presentation. Accelerated depreciation and decommissioning associated with repowering certain Southern Power wind facilities cost US$92 million after tax in the quarter and US$322 million for the first nine months. The company projects a further US$100 million of pre-tax costs in 2026 and US$135 million in 2027, with the projects expected to be completed through the third quarter of 2027.

Debt and regulatory charges complicate earnings quality

Southern Company also recorded US$40 million after-tax from debt extinguishment costs in the quarter, following the repurchase of certain convertible senior notes and redemption of junior subordinated notes. A further US$7 million after-tax estimated loss was recognised at Southern Company Gas for costs associated with Nicor Gas capital investments disallowed by the Illinois Commerce Commission in November 2025. The company said additional charges may occur, but their timing and amount remain uncertain.

Southern Company’s management said the Southeast is experiencing “unprecedented and transformational” growth and that the group is positioned to serve rising demand. The filing itself is more measured: it identifies substantial future generation and transmission investment needs, alongside risks involving capital access, revenue recovery, construction costs, regulatory approvals and customer affordability. The quarter demonstrates demand strength, but does not remove the execution and funding questions attached to meeting it.
