The earnings update comes after a period of steady share price gains, with Iberdrola’s latest close at €20.35, a 30 day share price return of 9% and a 1 year total shareholder return of 50.41%. This hints that investors have been reassessing both its growth prospects and risk profile as profits from its networks business have strengthened.

With Iberdrola’s shares up 50.41% over the past year and recent earnings reinforcing interest in its networks business, the key question now is whether the stock still offers value or if the market is already pricing in future growth.

Iberdrola’s most followed narrative estimates fair value at €17.89 per share, compared with the latest close at €20.35. The market price is therefore above that central estimate, which is built on a €17.9b valuation.

Major expansion of regulated network investments in the US and UK, supported by stable and attractive policy frameworks and recently approved regulatory determinations, is expected to nearly triple Iberdrola’s regulated asset base to €90bn by 2031. This should drive sustained, predictable growth in revenues and a structural increase in regulated net margins.

Read the complete narrative.

Curious what kind of revenue path, profit margins and future earnings multiple are built into that fair value, and how much relies on long term policy support and grid growth assumptions? The full narrative lays out the numbers behind that view.

Result: Fair Value of €17.89 (OVERVALUED)

However, if regulation tightens in key markets or financing costs rise, the earnings path behind that fair value could look far less comfortable.
