Eni S.p.A. shares trade at 24.14 EUR as the Italian energy group targets commercial nuclear fusion by the 2040s.

Eni S.p.A. shares closed at 24.14 EUR on Borsa Italiana on August 21, 2026, following a strong year-to-date gain of 49.57 percent. The Italian energy group currently holds a market capitalization of $88.88 billion, reflecting robust investor confidence in its long-term transition plans and underlying earnings power. While the company continues to focus on hydrocarbon exploration and production, it has recently outlined a strategic ambition to bring a commercial fusion power plant to Europe by the early 2040s. Management views nuclear fusion as a potential "next refinery" and a core component of its decarbonization pathway. Market analysis suggests that Eni S.p.A. remains undervalued compared to industry averages, trading at a P/E ratio of 12.1x against a peer group average of 12.9x. Despite a strong five-year return of 224.7 percent, the stock appears to trade at a significant discount to its fair earnings profile. Investors are currently weighing whether this valuation reflects a genuine mispricing or a risk premium for large-scale gas and transition projects.
