Endesa S.A. stock (ES0105128005): Q1 2026 earnings and May buyback underpin IBEX 35 utility

Endesa from Spain, listed on Bolsa de Madrid and a member of the IBEX 35 benchmark, stays on investors’ radar after publishing its Q1 2026 results in early May and continuing to retire shares through a buyback program, providing updated visibility on earnings, dividends and capital allocation according to the company’s investor relations information as of 05/06/2026 and a recent news overview on MarketScreener.

According to Endesa’s investor relations materials for Q1 2026, the Madrid-listed power group reported higher net profit for the period while revenue declined year on year, reflecting the mix of regulated grid activities and liberalized power generation and supply in Spain and Portugal, as summarized in a 05/06/2026 earnings call recap cited by MarketScreener.

As of 06/01/2026, a five-year comparison by finanzen.net showed that Endesa’s share price had risen from 22.02 EUR at the close five years earlier to 35.70 EUR, illustrating how the Spanish utility’s stock has appreciated on the home exchange over that horizon, although this backward-looking performance does not imply any particular future path.

In Spain, the stock trades primarily on Bolsa de Madrid in euros, and the company’s position in the IBEX 35 keeps it closely watched by domestic investors, while German investors can also access the shares via venues such as Tradegate and Frankfurt where Endesa is quoted in EUR, according to German market data summaries referencing the stock as of early June 2026.

Endesa S.A.: core business model

Endesa operates as a major Iberian energy player, combining regulated electricity distribution with power generation and retail energy supply to households and businesses, with revenue largely tied to electricity volumes, network tariffs and wholesale power prices in Spain and Portugal.

Recent corporate actions

A recent overview of corporate activity highlighted that Endesa has been executing a share buyback, with an ad-hoc-news summary noting that the company repurchased around 587,000 shares for approximately EUR 21.09 million in the final week of May 2026, which is part of an ongoing capital management framework that reduces the free float while potentially supporting earnings per share metrics, according to that disclosure and related commentary as of the last week of 05/2026.

Endesa S.A. in peer comparison

Within the European utilities landscape, Endesa is often compared with Iberdrola in Spain and Enel in Italy, both of which combine regulated network operations and large-scale generation portfolios, and peer data compiled around early 05/2026 by MarketScreener showed that these companies, like Endesa, face similar drivers from power demand trends and regulatory frameworks in their respective core markets.

While Endesa’s Q1 2026 revenue declined year on year as reported in the 05/06/2026 earnings materials, the company still posted higher net profit for the quarter, a pattern that broadly mirrors how peers balance profitability and top-line pressures, and peer comparisons also underline differences in geographic diversification, with Iberdrola having a wider international footprint and Enel holding a controlling stake in Endesa itself, according to the same MarketScreener overview.

Conclusion

With Q1 2026 earnings showing higher net profit despite lower revenue, Endesa’s latest results add fresh detail on how the Spanish utility is navigating its regulatory and market environment on Bolsa de Madrid.

The ongoing share buyback activity reported for the final week of May 2026 provides another lens on capital allocation, while peer comparisons with Iberdrola and Enel help frame Endesa’s relative positioning within the European utilities universe without implying any particular investment stance.
