Iberdrola came into this Q3 2026 report with its stock at €21.54, up about 6.1% over the past month but slightly softer over the last week. The utility is widely treated as a premium play on regulated grids and renewables; however, today’s headline is more grounded. Adjusted net profit for the first nine months reached €5.141b with adjusted earnings before interest, tax, depreciation and amortisation at €11.9b. That kind of earnings traction sits awkwardly against a share price already on a richer 25.7x P/E and leaves investors weighing growth strength against valuation strain.
Like Iberdrola’s earnings power but uneasy about paying 25.7x P/E for a regulated utility and renewables mix? Consider our 190 high quality undervalued stocks if you want a list that combines robust fundamentals with valuations that look less stretched.
Ask Charlie what Iberdrola’s 60% network RAB growth really means.
The bullish story hangs on Iberdrola turning data center demand into steadier, higher quality cash flow.
"Growing demand for clean electricity from data centers and electrification, supported by more than 12 terawatt hours a year of PPAs with technology companies and a strong U.S. and European pipeline, can support long term contracted volumes and contribute to revenue and cash flow stability."
On the ground, 9M 2026 numbers show the group already generating 91 TWh with 90% emissions free and lifting adjusted net profit 9%. That points to real scale behind those PPAs. Yet Q3 margin pressure in Iberia from procurement and ancillary service costs shows that contracted volume alone is not fully insulating earnings.

Concern around Iberdrola is that surging electrification loads strain grids without delivering clean earnings uplift.
"Rapid electrification from data centers and new industrial demand in the U.S. could outpace timely network upgrades and renewable additions, leading to congestion, curtailment and reliance on higher cost generation. This would pressure margins in both Networks and Renewables rather than delivering the smooth revenue uplift implied by current valuations."
Latest numbers partly echo that worry. Networks EBITDA grew to €6,430m and now represents 54% of group earnings power, so grid returns are holding. Yet Power & Customers EBITDA slipped about 2% as Iberia procurement and ancillary service costs bit into margins, showing that higher loads are not yet translating into smooth profitability.
Iberdrola shows how strong reported results can still leave investors debating what is already priced in. The real opportunity sits in finding stocks that could be undervalued before the market closes the gap.
