NEWS RELEASE

KOSMOS ENERGY ANNOUNCES FIRST QUARTER 2026 RESULTS

Delivers Record Quarterly Production

DALLAS - May 5, 2026-- Kosmos Energy Ltd. (“Kosmos” or the “Company”) (NYSE/LSE: KOS) announced today its financial and operating results for the first quarter of 2026. For the quarter, the Company generated a net loss of $226 million, or $0.45 per diluted share. When adjusted for certain items that impact the comparability of results, the Company generated an adjusted net loss(1) of $36 million, or $0.07 per diluted share for the first quarter of 2026.

FIRST QUARTER 2026 AND POST QUARTER END HIGHLIGHTS

•Net Production(2): ~74,800 barrels of oil equivalent per day (boepd), up ~25% versus first quarter 2025

•Revenues: $371 million, or $55.81 per boe (excluding the impact of derivative cash settlements)

•Production expense: $131 million (or $19.66 per boe), down ~22% versus first quarter 2025 (~$167 million)

•Capital expenditures: $91 million

•Greater Tortue Ahmeyim (GTA) gross production averaged ~2.85 million tonnes per annum (mtpa) for the first quarter, in excess of the floating LNG nameplate capacity (2.7 mtpa)

•Kosmos successfully completed a $350 million senior secured bond offering in the Nordic market

•Kosmos successfully completed an equity raise of approximately $200 million with the proceeds used to accelerate debt paydown

•Kosmos announced the sale of its interest in the Ceiba Field and Okume Complex in Equatorial Guinea, for up to ~$220 million

•The TEN partnership finalized the acquisition of the TEN FPSO, which is expected to result in a material reduction in operating expenses

•Kosmos took final investment decision for the operated Tiberius project in the Gulf of America

Commenting on the Company’s first quarter 2026 performance, Chairman and Chief Executive Officer Andrew G. Inglis said: “Earlier this year, we set four goals for 2026: increase production from our core assets; lower costs; reduce debt; and advance our high‑quality growth portfolio with minimal capital. We are delivering strongly on all four of these goals.

“In the first quarter, Kosmos achieved record daily and quarterly production, driven by GTA fully ramped up and new wells at Jubilee. Operating costs were ~22% lower year-on-year and we reduced net debt(1) by ~7% versus year‑end 2025. With this ongoing momentum, we have raised our full‑year debt reduction target from 10% to ~20%.

“We continue to maintain our capital discipline while we progress our quality growth options. We took final investment decision on the Tiberius development, entered into a strategic exploration alliance with Shell in the Gulf of America, and are moving forward on GTA Phase 1+ expansion.

“With oil prices higher, our goals are unchanged. We will direct excess free cash flow toward accelerated debt reduction and further strengthening the balance sheet. Our exposure to premium international oil markets positions Kosmos to capture value from current market dislocations and reinforces our confidence in the path ahead.”

FINANCIAL UPDATE

In January 2026, Kosmos successfully completed a $350 million senior secured bond offering in the Nordic market with proceeds used to repurchase ~$250 million of the Company's 2027 senior unsecured notes and to repay $100 million of borrowings under the reserve-based lending facility (RBL).

In March, Kosmos successfully raised approximately $200 million of equity with the proceeds used to accelerate debt repayment.

In April, Kosmos completed its spring RBL re-determination with the borrowing base reduced to approximately $1.25 billion. Post the sale of the Company's production assets in Equatorial Guinea, expected around midyear 2026, the borrowing base will reduce to approximately $1.2 billion,

Kosmos has growing exposure to higher near-term oil prices, with realizations and free cash flow expected to rise in the second quarter, taking account of the lag effect between sales and benchmark prices. In the second quarter so far, we have seen record pricing and record differentials for production priced off premium international benchmarks such as Dated Brent in Ghana.

Kosmos has taken advantage of a higher forward price curve to add further hedges for 2027. The company has 5.7 million barrels of oil hedged for the remainder of 2026 with an average floor of approximately $66/barrel and a further 4.0 million barrels hedged in 2027 with a floor of approximately $65/barrel.

Net capital expenditure for the first quarter of 2026 was $91 million, in line with guidance. Full year 2026 capital expenditure guidance of $350 million is unchanged.

The Company generated net cash provided by operating activities of approximately $107 million and free cash flow(1) of approximately $14 million. Kosmos exited the first quarter of 2026 with approximately $2.8 billion of net debt(1) and liquidity of approximately $488 million.
