Kosmos Energy's stock plummeted 5.15% during intraday trading on Monday, as investors reacted negatively to the company's latest quarterly results.

The oil and gas exploration firm reported a fourth-quarter adjusted loss per share of $0.16, significantly wider than the loss of $0.03 per share reported a year earlier and missing the analyst consensus estimate of a $0.13 loss. Revenue for the quarter fell 25.4% year-over-year to $296.5 million, also coming in below expectations.

Furthermore, the company posted a net loss of $377 million for the quarter, underscoring the challenging period. While Kosmos provided a positive outlook for 2026 production growth, the immediate focus of the market was on the substantial earnings miss and deteriorating profitability compared to the prior year.
