Hedge fund Toms Capital, backed by Citadel, has taken a major stake in Devon Energy, becoming one of its top five investors. This move occurs amid intensifying Permian Basin M&A activity following Devon's merger with Coterra Energy. While Devon faces pressure from activist Kimmeridge Energy, analysts speculate larger players like Exxon and Chevron may seek further targets. The rapid Coterra deal suggests regulatory openness to consolidation under the Trump administration.
