Most Popular Narrative: 2% Undervalued

PPL’s last close at $37.67 sits just below the most widely followed narrative’s fair value of $38.54, hinting at modest upside. The difference reflects ongoing optimism about PPL’s infrastructure investments and market positioning, setting the stage for a growth-focused bull thesis.

Major planned grid infrastructure upgrades and generation capacity expansions, totaling $20B through 2028 (with upside from potential data center-driven transmission and new generation projects), set the stage for nearly 10% average annual rate base growth. This directly supports higher regulated revenues and future earnings.

Another View: What Do the Market Multiples Say?

Looking through the lens of price-to-earnings, PPL’s ratio stands at 28.3x, notably higher than both the US Electric Utilities industry average (21.3x) and its peer average (19.1x).
