At 5:15 p.m., shares in the energy group were down 2.7%, while the Paris index was losing around 0.7%.

According to JPMorgan, the market now has a better grasp of the company, as shown by the recent narrowing of the valuation gap between Engie and its peers. The stock is currently trading at about 14 times expected 2026 earnings, compared to 10 times at the beginning of last October.

In its note, the research firm points out that the company has regularly exceeded expectations in recent years, despite a challenging environment marked by falling prices and high volatility.

Looking ahead, the firm expects Engie to report 2025 results at the upper end of its target range and to indicate that 2026 should mark the low point for its net profit.

Beyond 2026, JPMorgan forecasts earnings growth of around 5% per year in 2027 and 2028—a scenario that could disappoint investors hoping for a sharper rebound after the expected 2026 trough.

While the firm remains positive on Engie's growth prospects in renewables, with value creation ahead, it has also identified several headwinds, such as a strong euro and weaker-than-expected forward electricity prices in France.

In this context, the stock's recent strong performance seems to offer an opportunity to take profits, JPMorgan concludes, downgrading its recommendation from "overweight" to "neutral" with a price target of 24.5 euros. The firm says it prefers companies with higher earnings growth potential, particularly RWE and SSE.
