For the first quarter of 2019, Kosmos Energy Ltd.  generated a net loss of $53 million, or $0.13 per diluted share. When adjusted for certain items that impact the comparability of results, the Company generated an adjusted net loss of $23.0 million or $0.06 per diluted share for the first quarter of 2019.

"Kosmos has made a strong start to 2019 with progress across all business units and first quarter results in line with guidance," said Andrew G. Inglis, chairman and chief executive officer. "We remain on track to hit our production growth guidance for the year, while at current prices exceeding the 2019 free cash flow that we set out at our capital markets day in February. Our intention to sell down our position in Mauritania and Senegal to around 10% has generated significant industry interest and we have commenced a formal process, with bids expected by the end of summer. On the finance side, we successfully completed a $650 million bond offering during the quarter meaning Kosmos now has no debt maturities until 2022. We also paid our inaugural quarterly dividend in the first quarter."

It must be noted that the first quarter 2019 results include the impact of proportionately consolidating the Equatorial Guinea results. Prior quarters exclude this impact and only include the minority interest gain or loss in the bottom line. In addition, the prior year quarter does not include the Gulf of Mexico acquisition which did not close until the end of the third quarter of 2018.

First quarter 2019 revenues were $297 million on sales of 5.1 million barrels of oil equivalent (boe). Realized oil and gas revenues, including the impact of the Company's hedging program, was $56.73 per barrel in the first quarter of 2019. At quarter end, the Company was in a net underlift position of approximately 0.8 million barrels of oil. First quarter results included the following:

• Production expense was $80 million, or $15.64 per boe
• General and administrative expenses were $36 million, $28 million in cash expense and $8 million in non-cash equity based compensation expense
• Depletion and depreciation expense was $118 million, or $23.14 per boe
• Exploration expenses totaled $30 million
• Capital expenditures in the first quarter were $110 million

First quarter results included a mark-to-market loss of $77 million related to the Company's oil derivative contracts. At March 31, 2019, the Company's hedging position had a total commodity net asset value of approximately $39.5 million. As of the quarter end and including recently executed hedges, Kosmos has approximately 16 million barrels of oil hedged covering 2019 through 2020 including Brent, WTI, and LLS based hedges.

Kosmos exited the first quarter of 2019 with approximately $0.5 billion of liquidity and $2.1 billion of net debt.

OPERATIONAL UPDATE

Total net production volumes during the first quarter of 2019 averaged approximately 59,500 barrels of oil equivalent (boepd) per day*.

Ghana

During the first quarter of 2019, net production volumes from Ghana averaged approximately 28,620 barrels of oil per day (bopd), including net volumes from the Jubilee and TEN fields which averaged approximately 18,315 bopd and 10,305 bopd, respectively. Kosmos lifted two cargoes, as forecasted, from Ghana during the first quarter.

At Jubilee, gas handling reliability was enhanced during the quarter with a spare high-pressure gas compressor now available. Kosmos continues to work with the operator to increase the gas handling capacity, which would thereby allow oil production rates to increase.

At TEN, in March the EN-10 well was completed and brought online, increasing production from the field. An additional production well is expected to be brought on stream around the middle of the year, enabling the field to increase production rates to the FPSO nameplate oil capacity of 80,000 bopd gross.

Equatorial Guinea

Production in Equatorial Guinea averaged approximately 12,605 bopd net in the first quarter of 2019. Kosmos lifted the forecasted one and a half cargoes from Equatorial Guinea during the quarter. The electric submersible pump (ESP) program is on track, adding around 2,500 bopd gross to offset decline. Kosmos expects to complete two more ESP conversions around the middle of the year.

U.S.Gulf of Mexico

U.S.Gulf of Mexico production averaged approximately 18,240 boepd net (81% oil) during the first quarter, exceeding the high end of the guidance range.

The routine dry-dock work on the Helix Producer-1 was successfully completed on time, increasing production from the Gulf of Mexico once the vessel was brought back online. Production levels were further increased when the Tornado-3 well was brought online adding around 9,000 boepd gross.

Kosmos was one of the most active participants in U.S. Gulf of Mexico Lease Sale 252 in March and were the apparent high bidder on nine deepwater blocks.

During the first quarter of 2019, Kosmos farmed in to eighteen BP-owned blocks in the Garden Banks area of the deepwater U.S.Gulf of Mexico. In addition, Kosmos can earn an interest in three BP blocks in other areas of the deepwater Gulf of Mexico. This should allow Kosmos to execute projects that can be tied back to existing infrastructure. Kosmos is the designated operator and plans to commence drilling operations on the first well in Garden Banks Block 492, the Resolution prospect, in 2019.

Also, during the first quarter of 2019, Kosmos executed a farm-in agreement with Chevron covering the right to earn an interest in a strategic block in the deepwater U.S.Gulf of Mexico. This agreement allows Kosmos further opportunity to execute its deepwater U.S.Gulf of Mexico strategy of lower risk prospects with the potential for subsea development near existing infrastructure. Kosmos will be designated operator and plans to commence drilling operations on the first well in 2019.

Greater Tortue Ahmeyim Project

As of early May, all major contracts have been awarded for Tortue Phase 1, and construction activity for the project has commenced with work on the FPSO.

In April 2019, KBR was awarded the Pre-FEED services contract for Phases 2 and 3 of the Greater Tortue Ahmeyim project. These next phases are expected to expand capacity of this hub to almost 10 MMTPA of LNG for export.

In the wider Mauritania/Senegal basin, Kosmos has commenced a formal process to sell down its interest to around 10% with bids expected by the end of summer.

Portfolio Additions

Kosmos entered into a petroleum contract in March covering the Marine XXI block with the Republic of the Congo, subject to customary governmental approvals.  Upon approval, Kosmos will hold an 85% participating interest and will be the operator.

In March, Kosmos acquired Ophir's remaining interest in Block EG-24 offshore Equatorial Guinea, which resulted in Kosmos owning an 80% participating interest in in the block.

* Production means net entitlement volumes. In Ghana and Equatorial Guinea, this means those volumes net to Kosmos' working interest or participating interest and net of royalty or production sharing contract effect. In the Gulf of Mexico, this means those volumes net to Kosmos's working interest and net of royalty.
