Iberdrola S.A. (IBDRY) Stock Price & How to Invest

Iberdrola, S.A. is a Bilbao-based electricity group with two main businesses. Networks owns and runs regulated transmission and distribution grids in Spain (i-DE), the UK (SP Energy Networks, part of ScottishPower), the US (through Avangrid, whose utilities include New York State Electric & Gas, Rochester Gas and Electric, Central Maine Power and United Illuminating) and Brazil (Neoenergia). Power and Customers combines renewable generation (onshore and offshore wind, solar, hydro and storage), some conventional plants and a retail supply business. In 2025 revenue was ~€45.5 billion, reported net profit a record ~€6.29 billion and adjusted net profit ~€6.23 billion. The company ended 2025 with 58,343 MW of installed capacity, ~29.8 million supply contracts and ~45,400 employees, and says 83% of EBITDA comes from countries with A credit ratings.

Iberdrola was created in 1992 by the merger of Hidroeléctrica Española and Iberduero. Its international build-out came under Ignacio Sánchez Galán, who joined as chief executive in 2001 and has chaired the company since 2006: ScottishPower in 2007, Energy East in the US in 2008 (later combined with UIL Holdings to form Avangrid in 2015), and a growing Brazilian business through Neoenergia. In recent years it has bought out minority holders to own its networks outright, taking Avangrid private in December 2024 and buying Previ's ~30% stake in Neoenergia in 2025 for ~€1.9 billion. It has also exited Mexico, selling most of its plants there in 2024 and the remaining business to Cox in April 2026 for ~US$4 billion, which produced a ~€953 million net capital gain in the first half of 2026.

Ownership is widely spread, with institutions and Spanish retail investors holding most of the shares. Qatar Investment Authority remained the largest shareholder at 6.98% at the end of 2025, down from 8.69% a year earlier, followed by BlackRock at ~6.0%. Galán is executive chairman, and his long tenure is closely tied to the company's strategy of steady dividend growth funded by large capital programs.

The investment picture centers on the 2025-2028 strategic plan presented in London on September 24, 2025: ~€58 billion of investment through 2028, with the UK (~€20 billion) and the US (~€16 billion) the largest destinations, a 2028 EBITDA target of ~€18 billion with networks supplying ~55%, and ~€20 billion of dividends over the four years at a 65% to 75% payout with a €0.64 per share floor. In the US, IBDRY trades OTC in dollars, and each ADR represents four ordinary shares listed on the Spanish stock exchanges as IBE. ADR dividends are paid in dollars after Spanish withholding tax and depositary fees.

Iberdrola's growth depends on regulators. Returns in the UK are set by Ofgem price controls, in the US by state commissions in New York, Maine and Connecticut, and in Brazil and Spain by national regulators, so a tougher rate decision or a political push to cap bills can cut the return on billions of euros of new investment. The push into data-center-driven demand also assumes that load actually arrives. Debt is rising: adjusted net debt reached ~€54 billion at mid-2026 and is expected near €56 billion by year end before the ~€2 billion Caruna payment, so higher interest rates or a credit downgrade would squeeze the economics of the investment plan. Renewables carry their own exposure. Spain recorded a record ~2.5 TWh of curtailment in the first half of 2026 according to Aurora Energy Research, 50% more than in all of 2024, and Aurora expects curtailment to keep rising, and offshore wind projects face cost inflation, supply chain bottlenecks and permitting delays. Power and Customers EBITDA barely grew in the first half, and the reported 22% profit rise relied on a one-off ~€953 million Mexico gain. Currency moves between the euro, pound, dollar and Brazilian real shift reported results: FX cut first-half adjusted net profit growth from 14% to 8%. For ADR holders, Spain withholds tax on dividends (at a standard 19% rate), and recovering any treaty excess takes paperwork, while thinner OTC trading and dollar conversion add costs.

We give no verdict on Iberdrola S.A.. Both cases are real, which is why the question is contested at all, so here is the strongest version of each.

The case for buying. Grid investment and the regulated asset base. Networks are now the growth engine.

The case against. Iberdrola's growth depends on regulators.

A simple financial snapshot. These are approximations and refresh quarterly; for current figures see Iberdrola S.A.'s investor relations page or your broker.

• Revenue (TTM to June 2026): ~€45.9B
• Adjusted net profit (TTM): ~€6.5B
• 2026 adjusted net profit guidance: >€6.7B (growth above 8%)
• Market cap: ~€140B at ~€21.26 (IBDRY ~$95)
• Adjusted net debt: ~€54.0B (FFO/debt 22.4%)
• Dividend (2025): €0.685 per share (~3.2% yield)

At roughly €140 billion, Iberdrola trades at about 21 times its 2026 adjusted profit guidance of more than €6.7 billion, a premium to most European utilities that reflects how much of its earnings now comes from regulated networks with visible growth. Adding ~€54 billion of net debt gives an enterprise value near €195 billion against 2025 EBITDA of ~€16.6 billion reported. Trailing reported profit of ~€7.1 billion is higher than adjusted because of the Mexico gain. The ~3.2% dividend yield is modest for a utility, which is consistent with a market that values Iberdrola for growth rather than income. Market cap is estimated from the ~€4.5 billion total 2025 payout at €0.685 per share, implying ~6.6 billion shares.

Other names that sit close to IBDRY: same theme, named as a direct competitor, or held beside it in the same funds. Each entry says which. Worth a look if you are thinking about diversification within a thesis rather than concentration on one ticker.

There are three common ways to get IBDRY exposure. Buy shares (or fractional shares) directly at any major broker. Hold an ETF that includes it, which spreads the position across many companies. Or build it into a focused thematic portfolio, so IBDRY sits alongside other stocks that express the same thesis.

Walnut takes the portfolio route. Describe a thesis where IBDRY fits (for example “AI infrastructure” or “dividend-growth large-caps”) and the AI proposes 5 to 6 constituents with target weights. You review the plan and fund it through your own broker when you're ready.
