Earnings call transcript: Endesa's Q2 2025 results show strong growth

Endesa S.A. reported robust Q2 2025 financial results, with EBITDA up 12% to €2.7 billion and net income rising 30% to €1 billion, alongside doubled free cash flow, driven by strong growth and significant renewable energy capacity additions. Despite facing market volatility and an estimated €150 million impact from ancillary services costs due to a recent blackout, the company maintains stable debt and targets the top end of its full-year guidance, supported by an ongoing share buyback program. A critical factor for future investment and Spain's energy transition remains the regulatory framework for grid remuneration, which Endesa views as currently insufficient but anticipates a more favorable final version.

Analysis

Endesa S.A. delivered a robust Q2 2025 financial performance, with EBITDA increasing 12% year-on-year to €2.7 billion and net income rising 30% to €1 billion, driven by the removal of a prior-year extraordinary levy and favorable gas hedging positions. Despite management characterizing the period as a "horrible quarter" due to a significant spike in ancillary service costs following a major blackout, which created a €150 million headwind, the company demonstrated operational resilience by reaffirming its target for the top end of its full-year guidance. Strategically, Endesa continues to advance its decarbonization goals, adding 0.7 gigawatts of renewable capacity to bring its emission-free generation to 79% of its mainland mix, while returning capital through a €500 million share buyback program that is approximately 70% complete. The most critical forward-looking factor is the unresolved regulatory framework for grid remuneration; Endesa views the current proposal as insufficient and believes it endangers Spain's energy transition, creating a significant uncertainty that directly impacts its future capital investment plans and ability to meet surging power demand, which is already causing an 80% rejection rate for new grid connection requests.

Key Decisions for Investors

• Investors should closely monitor the final regulatory decision on network remuneration, as this will be the primary catalyst determining the balance between accelerated capital investment and enhanced shareholder returns.
• Assess the sustainability of margins in light of significant customer churn and the company's exposure to volatile ancillary service costs, which presented a notable headwind in the first half.
• While the reaffirmed top-end guidance and active share buyback program signal management's confidence, the resolution of the grid investment framework remains the most critical factor for the long-term investment thesis.
• Watch for developments on a potential postponement of nuclear plant shutdowns and the launch of capacity market auctions, as these represent potential, though currently uncertain, positive catalysts for future earnings.
