The share price of Kosmos Energy Ltd. (NYSE:KOS) fell by 10.68% between December 10 and December 17, 2025, putting it among the Energy Stocks that Lost the Most This Week.
Kosmos Energy Ltd. (NYSE:KOS) is a leading deepwater exploration and production company focused on meeting the world’s growing demand for energy.
On December 12, Mizuho analyst William Janela lowered the firm’s price target on Kosmos Energy Ltd. (NYSE:KOS) from $2 to $1.50, but maintained a ‘Neutral’ rating on its shares. The adjustment comes as the analyst’s firm updated its ratings and targets in the exploration and production sector as part of its 2026 outlook. While the American oil and gas sector is currently witnessing a downside on the back of oversupply issues and high gas storage, the analyst sees ‘underappreciated value’, particularly in the exploration and production group.
Earlier on December 5, BofA analyst Matthew Smith also double-downgraded Kosmos Energy Ltd. (NYSE:KOS) from ‘Buy’ to ‘Underperform’, while also significantly reducing its price target from $3.4 to $1. The downgrade comes after the analyst firm trimmed its Brent oil price forecasts for 2026 and 2027 to $60 and $62 per barrel, respectively.
Kosmos Energy Ltd. (NYSE:KOS) had a scare on December 10 following reports that the Senegalese government is planning to nationalize the Yakaar-Teranga project, one of the world’s largest gas discoveries in recent years. Kosmos operates the project, and the energy operator also owns a 90% stake in it. However, the company later confirmed that the Senegalese energy ministry has no intentions of nationalizing the gas field. Kosmos also added that it will return its license for the project by July 2026 if it fails to find a new partner.
