Kosmos Energy's stock fell 6.12% in pre-market trading on Tuesday following the release of its first-quarter 2026 financial results.

The deepwater oil and gas producer reported revenue of $371 million, falling short of the analyst consensus estimate of $419.93 million. The company also posted an adjusted loss per share of $0.07, missing expectations for a profit of $0.04.

Despite reporting a record quarterly production of approximately 74,800 barrels of oil equivalent per day, a 25% increase year-over-year, and a narrowed adjusted net loss compared to the first quarter of 2025, the significant misses on top and bottom-line estimates appear to have driven the negative investor sentiment in the pre-market session.
