Southern (SO) Heads To The American Growth Summit, Is It Still Below Fair Value?

Simply Wall St · 1d ago

Southern (SO) heads into its American Growth Summit appearance in Washington on 29 September 2026, with CEO Christopher C. Womack addressing investors as the utility’s shares trade near US$83.79 and carry a market value around US$96.3b.

Southern’s share price has edged higher over the past week, but that short burst of momentum follows a 30 day share price return that fell 4.9% and a 90 day share price return that declined 13.9%, even as total shareholder return over five years reached 62.45%.

After that recent slip yet a share price still near US$83.79, the real question for Southern is where fair value sits between its current quote and a wide range of analyst and intrinsic estimates.

Most Popular Narrative: 16% Undervalued

Southern is trading below the most widely followed fair value estimate of about $99.76, so the spotlight falls on what could justify that gap and whether the growth story can carry the current premium P/E over the long haul.

Accelerating large-load and data center activity in Southern’s territories, including more than 17 GW of contracted large-load agreements for the mid 2030s, a late stage pipeline of about 8 GW and a prospective funnel above 75 GW, points to a long runway of usage driven revenue and regulated rate base growth that may not be fully reflected in current valuation.

See why 65 investors see Southern as 16% undervalued.

Result: Fair Value of $99.76 (UNDERVALUED)

Still, the Southern story can be knocked off course if large data center contracts slow or if heavy DOE-backed and equity funding pressures future earnings power.

Another View: Southern Through The DCF Lens

While the popular narrative pegs Southern around a $99.76 fair value using analyst earnings and multiples, the Simply Wall St DCF model lands in a very different place. On that future cash flow view, SO at $83.79 screens as expensive versus an estimated value of about $3.73. Which approach do you trust more when the gap is this wide?

Our DCF model is only as useful as the assumptions behind it, so it is worth understanding how it treats growth, capital spending and discount rates before leaning on it too heavily for decisions. Look into how the SWS DCF model arrives at its fair value.
