Another View on Iberdrola’s Valuation

While the popular Iberdrola fair value narrative points to a 10.9% discount at €23.80, the current P/E ratio of 24.7x tells a tougher story. That multiple sits well above both the European Electric Utilities average of 16.5x and peer levels, suggesting investors are already paying up.

The fair ratio of 25.1x is only slightly higher than Iberdrola’s current P/E, which narrows the gap between “premium” and “fairly priced” and leaves less room for error if earnings or regulation disappoint. The question is whether you are comfortable underwriting that premium today.
