Kosmos Energy (NYSE:KOS) reported a fourth-quarter net loss of $377 million, or $0.79 per share, as the company prioritized balance sheet discipline and portfolio optimization at the close of 2025.
On an adjusted basis, which excludes certain non-cash items and one-time charges, the Dallas-based explorer posted a net loss of $78 million.
The quarterly results arrived amid a significant ramp-up in operational activity.
Net production for the fourth quarter averaged approximately 67,900 barrels of oil equivalent per day (boepd), while current production has already climbed to roughly 75,000 boepd.
This growth is underpinned by a robust reserve base, with the company reporting year-end 1P proved reserves of approximately 250 million barrels of oil equivalent (mmboe) and 2P proved and probable reserves of 500 mmboe.
Meanwhile, management demonstrated tightened fiscal control throughout the year, with full-year 2025 capital expenditures totaling $292 million, approximately 25% below its original guidance.
This spending discipline is paired with an aggressive deleveraging strategy.
Kosmos recently secured a $350 million bond offering to repay its 2026 notes and reached an agreement to divest its Equatorial Guinea assets for up to $220 million.
