PPL (PPL) is drawing investor attention after outlining a planned US$23 billion investment program through 2029, supported by disciplined cost management and closely tied to its current earnings guidance.

Despite the fresh US$23 billion investment plan and grid upgrade story, PPL's recent momentum has softened, with the share price down over the past quarter. However, the 3 year total shareholder return of 40.04% and 5 year total shareholder return of 47.30% reflect a stronger longer term record.

After a softer recent share price patch, despite PPL outlining a US$23 billion grid plan and sitting below analyst price targets, is more of the potential already reflected in the stock, or does valuation still leave room ahead?

Most Popular Narrative: 14.1% Undervalued

PPL's most followed narrative sets a fair value of $41.20 per share, above the last close of $35.41, and ties that gap directly to its long-term capital plan.

The accelerating growth in data center construction and new economic development (particularly in Pennsylvania and Kentucky) is driving unprecedented electricity demand, positioning PPL for outsized long-term rate base and revenue growth as it invests to serve these large new loads.

Curious what is baked into that $41.20 figure? The narrative highlights steady grid spending, firmer margins, and a future earnings multiple that requires careful scrutiny.

Result: Fair Value of $41.20 (UNDERVALUED)

However, PPL's concentration in a few U.S. regulatory jurisdictions and its reliance on large data center loads mean that shifts in policy or demand could quickly challenge this undervaluation story.

Another View: SWS DCF Model Paints A Harsher Picture For PPL

While the most popular PPL narrative points to a fair value of $41.20 and labels the stock as 14.1% undervalued, the SWS DCF model points the other way with an estimate of $19.97 per share. This makes the current $35.41 price look expensive and raises the question of which story you trust more.
