Acciona's stock moved lower on the day, trading down nearly 3.0% to around 244.8 after the group published first-half 2026 results that showed a pronounced fall in profitability.
The company reported attributable net profit of 23 million for the period, an 84.3% decline compared with the same six months a year earlier. The reduction in headline profit largely reflected the absence of asset rotation gains that had supported earnings in H1 2025. Two significant asset disposals that could have contributed to first-half results instead completed in July, after the reporting period had closed.
The deterioration was particularly notable at Acciona Energ eda, the group's listed renewable energy arm. That unit swung to a net loss of 18 million in H1 2026, reversing a net profit of 455 million in the prior-year period. EBITDA at Acciona Energ eda contracted sharply as Spanish wholesale electricity prices eased amid what the company described as renewable oversupply and weaker demand, leading to lower realised prices and a significant reduction in generation revenues.
Company management highlighted the two July disposals - a 64 MW hydro portfolio and a 361 MW wind portfolio in Spain - which together brought in approximately 50 million in proceeds. Executives said those transactions would materially strengthen second-half results. Despite that guidance, investors opted to sell into the news and reassess once the benefits of the July sales flow through to the accounts.
The wider market environment provided limited support. Spain's IBEX 35 index had fallen in the previous trading session, and the renewable energy and utilities sector across the Iberian Peninsula has faced persistent headwinds throughout 2026 from compressed electricity prices.
Analyst sentiment around Acciona remains cautious. The majority of covering analysts carry sell ratings, and the consensus price target sits well below the level at which the stock was trading entering the session. That sceptical consensus, combined with the headline profit miss driven by the absence of asset rotation income and the loss-making performance at the renewable unit, served as a clear catalyst for the day s selloff, even as management reaffirmed full-year guidance and signalled a stronger second half.
Summary
Acciona's H1 2026 results showed a steep decline in attributable profit to 23 million, driven by the non-recurrence of asset rotation gains and a swing to a loss at Acciona Energ eda amid weak wholesale electricity prices. Two asset sales closed in July should bolster H2 results, but investors and analysts reacted negatively to the earnings release.
