Iberdrola S.A. stock (ES0144580Y14): Madrid utility starts new share buyback as IBEX 35 softens

Iberdrola S.A. began a new share buyback on Bolsa de Madrid on 06/01/2026 while the IBEX 35 opened June lower and the Spanish utility’s stock edged down modestly in early trading.

Iberdrola S.A., the Spanish-listed power group, started trading the new month on Bolsa de Madrid under the shadow of a softer IBEX 35 and the launch of its latest share buyback program on 06/01/2026, as investors reassessed utilities against a backdrop of broader market weakness and capital-return plans, according to Dow Jones reporting cited by Futu News on 05/29/2026 and market color from Reuters on 06/01/2026.

According to a Dow Jones dispatch carried by Futu News on 05/29/2026, Iberdrola planned to commence a new share repurchase program on 06/01/2026, adding to its toolkit of capital returns for shareholders at a time when European utilities remain in focus for their dividend and buyback policies.

In parallel, the Spanish blue-chip IBEX 35 started June in negative territory on 06/01/2026 as investors monitored developments around the Strait of Hormuz and upcoming U.S. macroeconomic data, with Iberdrola shares slipping around 0.3% in early trading that day, according to Reuters coverage of the Madrid market on 06/01/2026.

The stock traded on Bolsa de Madrid under ticker IBE at around EUR 12 in the first session of June 2026, reflecting a small decline versus the previous close as the index moved lower, according to intraday quotations on the Spanish exchange as of 06/01/2026.

For domestic investors in Spain, the combination of the new buyback program and the modest early-session price move on 06/01/2026 keeps Iberdrola squarely in focus as one of the heavyweight constituents of the IBEX 35 and a major component of the national utilities sector.
