Southern (SO): Valuation Check After Georgia Power Wins Approval to Expand Data Center Capacity

Simply Wall St·12/22/2025 11:10:21
Listen to the news

Southern (SO) just secured a major green light in Georgia, where regulators unanimously approved Georgia Power’s plan to boost capacity to meet the AI-driven data center surge across the state.

See our latest analysis for Southern.

Despite the regulatory win, Southern’s recent share price return has cooled, with a roughly 9 percent 3 month pullback and softer 1 month performance, even as its 5 year total shareholder return of about 72 percent signals durable, long term compounding.

If this AI driven demand story has you thinking beyond a single utility, it could be a good moment to explore high growth tech and AI stocks for other potential beneficiaries of the trend.

With shares lagging recently but still trading below the average analyst target, is Southern a steady utility temporarily out of favor, or has the AI driven growth story already been fully priced in by the market?

Most Popular Narrative: 14.1% Undervalued

At a last close of $85.28 versus a narrative fair value near $99, Southern is framed as modestly mispriced, with future earnings power doing the heavy lifting.

The expansion of large scale electrification projects including hyperscaler data centers and industrial developments across Alabama, Georgia, and Mississippi is materially increasing Southern's load outlook, resulting in regulatory approvals and filings for up to 10 GW of new generation and $13 billion of incremental capital investment, driving long term earnings and rate base growth.

Read the complete narrative.

Want to see the math behind that upside gap? The narrative leans on steady revenue growth, rising margins, and a premium future earnings multiple. Curious which assumptions really move the needle.

Result: Fair Value of $99.23 (UNDERVALUED)

Have a read of the narrative in full and understand what's behind the forecasts.

However, elevated capital needs, potential equity dilution, and any cooling in data center demand could quickly challenge today’s earnings assumptions and valuation upside.

Another View: Multiples Paint a Richer Picture

Our fair value narrative suggests upside, but the earnings multiple tells a more demanding story. Southern trades on a 21.1x P/E versus 19.4x for US electric utilities, even as its fair ratio points closer to 25.2x. Is this a bargain in progress or optimism already reflected?
