The story

Kosmos Energy was established in 2003 by founding partners James C. Musselman, Brian F. Maxted, W. Greg Dunlevy, and Paul Dailly. Initial backing came from American private equity firms Warburg Pincus and The Blackstone Group. Originally, it was incorporated in Bermuda.

Kosmos made one of the world's largest recent oil discoveries in June 2007, off the coast of Ghana. The company discovered the Jubilee Oil Field about 60 kilometres (37 mi) offshore. The first oil from the field was produced in 2010. The company and its operations in Ghana, around the time of the Jubilee discovery and work to develop the field, was the focus of Rachel Boynton's 2013 documentary-film Big Men. The documentary was shortened and adapted into a BBC television documentary Storyville: Power, Money, Greed and Oil.

Kosmos went public under the ticker symbol KOS on the New York Stock Exchange on May 10, 2011. The initial public offering raised more than anticipated, selling 33 million shares at $18 each. It was listed on the London Stock Exchange on August 21, 2017.

Kosmos and Chevron reached a deal in June 2012, where subsidiary Chevron Global Energy Inc. received a 50% working interest in Block 45 and Block 42 in Suriname, to boost operations. In May 2016, Kosmos reached a farm-out agreement with a subsidiary of Hess Corporation, wherein Hess acquired a 33% non-operated interest in Block 42 from Kosmos and Chevron.

Kosmos began a controversial oil drilling project in the Cape Bojador area in 2014 off the coast of the disputed territory of Western Sahara. In an article from February 2015, former UN legal counsel Hans Corell stated that exploration activities by Kosmos and Glencore were in violation of the legal opinion he wrote for the UN Security Council. Kosmos responded that its operations complied with international law and were consistent with the UN opinion. Kosmos officials also told media it recognized that its work in the area must occur alongside UN-led mediation.

The company said local populations in Western Sahara would benefit from the economic development of the region. A Kosmos official told Reuters, "If we are successful, we believe responsible resource development has the potential to create significant social and economic benefits for Western Sahara and its people. We have worked in close partnership with Morocco — as the de facto administering power of the territory. They have a vital role to play in ensuring benefit sharing, among other important issues, will happen should we be successful".

In 2016, Norway's Council on Ethics recommended that the country's Government Pension Fund Global exclude Kosmos Energy and Cairn Energy Plc. from its investment portfolio due to their activities in Western Sahara. In June 2016, the Financial Times quoted Kosmos correspondence with the Council on Ethics: "We fundamentally disagree with the council's assessment of our activities offshore Western Sahara, where we have spent considerable time on the ground working with local people to understand their views of oil and gas exploration. The council's decision fails to recognize that people in Western Sahara—whom we have met in hundreds of face-to-face conversations—want the economic opportunities that come from increased foreign investment." In February 2018, Kosmos announced its withdrawal from Morocco and Western Sahara, marking the end of 17 years of companies in the oil sector there.

Kosmos made two significant gas discoveries offshore Mauritania in 2015. Kosmos discovered gas at its Tortue-1 exploration well in Block C-8 in April 2015, followed by another gas discovery in its Marsouin-1 exploration well, which was later renamed Bir Allah, in the northern part of Block C-8. A few kilometers south of Tortue-1, Kosmos Energy discovered gas at its Guembeul-1 exploration well offshore Senegal in January 2016.

The company continued to make gas discoveries in 2016 and 2017, including significant natural gas resources at the Teranga-1 exploration well offshore Senegal in 2016. In December 2016, Kosmos and BP entered a partnership in Mauritania and Senegal. BP acquired a 62% working interest, including operatorship, of Kosmos' exploration blocks in Mauritania and a 32.49% effective working interest in Kosmos' Senegal exploration blocks. In May 2017, the two companies made a major discovery off the coast of Senegal while drilling the Yakaar-1 exploration well.

Senegal and Mauritania signed a cooperation agreement to allow for Kosmos and BP to develop gas resources shared by the two counties in February 2018. BP and Kosmos made a final investment decision on the Tortue project in December 2018, leading to the first phase of the Tortue LNG development.

Kosmos Energy acquired Deep Gulf Energy, expanding Kosmos' oil and gas operations into the Gulf of Mexico, in August 2018. In December 2018, Kosmos was reincorporated in Delaware. Previously, it was incorporated in Bermuda.

Products and brands

As of 2021, Kosmos Energy produces oil and gas in Equatorial Guinea, Ghana and the Gulf of Mexico, and has a license to explore in one block offshore São Tomé and Príncipe. In December 2016, BP entered into a partnership with Kosmos, whereby BP became the operator of Kosmos's exploration blocks in Senegal and Mauritania, which includes the Greater Tortue Ahmeyim (GTA) liquefied natural gas project. Previously it operated also in Morocco and Western Sahara but has ended its operations there.

Ghana

Kosmos Energy discovered the Jubilee Oil Field in 2007. The Jubilee field is estimated to hold up to 1 billion barrels (160 million cubic metres) of oil and 800 billion cubic feet (23 billion cubic metres) of natural gas. United States Secretary of State Hillary Clinton reportedly advocated for Kosmos and other U.S.-based oil companies in Ghana as Kosmos began development of the Jubilee field. In addition to Jubilee, Kosmos is a partner on the TEN (Tweneboa, Enyenra and Ntomme) project developing the Tweneboa, Enyenra, and Ntomme hydrocarbon accumulations. Oil first flowed from TEN in 2016, which sits approximately 30 nautical miles (60 kilometres) off the coast of Ghana.

In 2016, Kosmos owned a 24.1% stake in Jubilee and a 17% stake in TEN. Kosmos announced in late 2021 it had acquired an additional 18% interest in the Jubilee Field and an additional 11% interest in the TEN field, both from Occidental Petroleum Corporation for $550 million. The 2021 transaction was subject to a 30 day pre-emption period, which was exercised by Tullow Oil reducing Kosmos' total interest in Jubilee to 38.3% and TEN to 19.8%.

Equatorial Guinea

In October 2017, Kosmos entered a 50:50 joint venture with Trident Energy to acquire Hess Corporation's interest in the Ceiba Field and Okume Complex assets offshore Equatorial Guinea. Kosmos also has interests in exploration blocks offshore Equatorial Guinea. In November 2019, Kosmos announced an oil discovery at its S-5 well offshore of Equatorial Guinea.

Gulf of Mexico

Kosmos Energy entered the deepwater Gulf of Mexico in August 2018 when it acquired Deep Gulf Energy from First Reserve, a private equity firm, for $1.23 billion. Kosmos Energy paid $925 million in cash and $300 million in common stock to acquire DGE. As a result of the transaction, Kosmos Energy increased its daily production by more than 50% to 70,000 barrels of oil equivalent; estimated reserves increased 40% to 280 million barrels of oil equivalent.

Mauritania and Senegal

Kosmos has operated in the Cayar and St. Louis blocks offshore Senegal. At the time of operation it held a 32.51% interest in each of the two exploration licenses.

In Mauritania, Kosmos has acreage in the C8 and C12 blocks which range in depth from 100 to 3,000 meters. C8 and C12 are located on the western margin of the Mauritania Salt Basin offshore Mauritania.

It made a significant gas discovery at its Tortue-1 well in Block C-8, offshore Mauritania, in April 2015. The well was drilled to test the Tortue West prospect, forming a part of the Greater Tortue complex. Its next discovery offshore came at Kosmos' Marsouin-1 exploration well, later renamed Bir Allah, in the northern part of Block C-8. With results from its Ahmeyim-2 appraisal well, Kosmos estimated the Tortue West contains 15 trillion cubic feet (420 billion cubic metres) of gas, and the Greater Tortue Complex contains more than 20 trillion cubic feet (570 billion cubic metres). Company officials said this discovery confirmed that the Tortue gas resource, which is also called Ahmeyim, straddles the maritime boundary between Senegal and Mauritania.

Kosmos and BP have a farm-out agreement over the joint gas discovery in Mauritania and Senegal, as well as future exploration. Under the deal, Kosmos focuses on exploration, while BP controls development and production operations. The two companies have discovered an estimated 15 trillion cubic feet (420 billion cubic metres) of gross Pmean gas resource at the Yakaar-1 exploration well. At the end of 2018, Kosmos Energy announced a final investment decision for phase 1 of the Greater Tortue Ahmeyim LNG Project alongside BP.

The Greater Tortue Ahmeyin (GTA) natural gas field is being developed to produce gas from a deepwater system to a midwater floating production storage and offloading (FPSO) vessel. The FPSO processes the gas for liquefaction and sends the gas via pipeline to a floating liquefied natural gas (FLNG) facility. The FLNG facility is located on the Mauritania and Senegal maritime border. As of September 2022, phase 1 of the Greater Tortue Ahmeyim project was expected to begin production in 2023 with an estimated yield of approximately 2.5 million tons annually; a final investment decision had not been reached for phase 2. The GTA project will provide global export and provide gas availability for domestic use in Mauritania and Senegal.

Kosmos Energy confirmed gas resources at the Yakaar-2 appraisal well offshore Senegal. In October 2019, Kosmos made a major gas discovery at its Orca-1 exploration well offshore Mauritania. The company estimated the total gas available as 100 trillion cubic feet.

In October 2019, Kosmos made a major gas discovery at its Orca-1 exploration well offshore Mauritania. The company estimated the total gas available offshore Mauritania and Senega as 100 trillion cubic feet of gas.

Suriname

In Suriname, Kosmos operated in two exploration licensed areas. It held a 50% interest in Block 45 and a 33% interest in Block 42. In 2018, it abandoned two exploration wells, Anapai-1A in Block 45 and Pontoenoe-1 in Block 42, because the company failed to find hydrocarbons. Royal Dutch Shell acquired Kosmos Energy's offshore Suriname position in December 2020.

Morocco and Western Sahara

As operator, Kosmos held a 55% interest of the Boujdour Maritime block and 75% interest of the Essaouira block. In October 2013, Kosmos reached a farm-out deal with Cairn Energy subsidiary Capricorn Exploration & Development Company Ltd. Under the deal, Cairn took a 20% non-operated interest in Boujdour Maritime block.

The license of the Boujdour block was signed with the Moroccan state oil company ONHYM.

Kosmos announced in May 2014 it would plug and abandon its FA-1 well in the Foum Assaka Offshore block. While it did not find oil, the company said there was evidence of a working petroleum system and the well provided important seismic calibration details. These details were incorporated into the company's petroleum system analysis.

On March 2, 2015, Kosmos Energy said its CB-1 exploration well in Cap Boujdour made a small discovery. The discovery was noncommercial, and the well was plugged and abandoned in February 2018.

Other African countries

Kosmos had ownership interests in six blocks offshore Sao Tome and Principe, including two blocks where Kosmos partnered with BP. In 2018, Kosmos announced it would explore a number of blocks offshore with Royal Dutch Shell. Shell purchased five of the Kosmos blocks in 2020. As of 2022 Kosmos continues to have an interest in Block 5 in Sao Tome.

With Galp, Kosmos ordered a 3D seismic survey of a large stretch of ocean floor. According to The Wall Street Journal, the survey was "one of the biggest offshore oil exploration efforts of its kind in the region". The survey was completed on August 20, 2017.

Kosmos Energy had an offshore license in Congo-Brazzaville for the Marine XXI block, which covered more than 2,300 square km. The company signed a production sharing agreement with Congo-Brazzaville and the Société Nationale des Pétroles du Congo. Kosmos terminated the contract in February 2020.

In 2018, Kosmos Energy partnered with Royal Dutch Shell to explore blocks offshore Namibia. In September 2020, Shell entered into an agreement to farm down Kosmos' portfolio of frontier exploration assets.

Risk factors and legal proceedings

The risks Kosmos Energy names in Item 1A of its 10-K filed Mar 2, 2026: 51 risks under these headings, as written.17

  • Our Oil and Natural Gas Operations
  • Our Business and Financial Condition
  • General Matters
  • Risks Relating to our Oil and Natural Gas Operations
  • We have limited proved reserves and areas that we decide to drill may not yield oil and natural gas in commercial quantities or quality, or at all.
  • We face substantial uncertainties in estimating the characteristics of our discoveries and our prospects.
  • Drilling wells is speculative, often involving significant costs that may be more than we estimate, and may not result in any discoveries or additions to our future production or reserves. Any material inaccuracies in drilling costs, estimates or underlying assumptions will materially affect our business.
  • Development drilling may not result in commercially productive quantities of oil and gas reserves.
  • Our identified drilling and infrastructure locations are scheduled out over time, making them susceptible to uncertainties that could materially alter the occurrence or timing of their drilling or infrastructure installation or modification.
  • Under the terms of certain of our petroleum contracts, we are contractually obligated to drill wells and declare any discoveries in order to retain exploration and production rights. In the competitive market for our license areas, failure to drill these wells or declare any discoveries may result in substantial license renewal costs or loss of our interests in the undeveloped parts of our license areas, which may include certain of our prospects or undeveloped discoveries.
  • The inability of one or more third parties who contract with us to meet their obligations to us may adversely affect our financial results.
  • The unit partners’ respective interests in the Jubilee Unit and Greater Tortue Ahmeyim Unit are subject to redetermination and our interests in each such unit may decrease as a result.
The other 43 risks
  • We are not, and may not be in the future, the operator on all of our license areas and facilities and do not, and may not in the future, hold all of the working interests in certain of our license areas. Therefore, we have reduced control over the timing of exploration or development efforts, associated costs, and the rate of production of any non‑operated and to an extent, any non‑wholly-owned, assets.
  • Our estimated proved reserves are based on many assumptions that may turn out to be inaccurate. Any significant inaccuracies in these reserve estimates or underlying assumptions will materially affect the quantities and present value of our reserves.
  • The present value of future net revenues from our proved reserves will not necessarily be the same as the current market value of our estimated oil and gas reserves.
  • We may not be able to commercialize our interests in some of the natural gas produced from our license areas.
  • Our inability to access appropriate equipment and infrastructure in a timely manner may hinder our access to oil and natural gas markets or delay our oil and natural gas production.
  • We are subject to numerous risks inherent to the exploration and production of oil and natural gas.
  • We are subject to drilling and other operational and environmental risks and hazards.
  • Our operations may be materially adversely affected by weather-related events, including, but not limited to, tropical storms and hurricanes, and the physical effects of climate change.
  • The development schedule of oil and natural gas projects, including the availability and cost of drilling rigs, equipment, supplies, personnel and oilfield services, is subject to delays and cost overruns.
  • Our offshore and deepwater operations involve special risks that could adversely affect our results of operations.
  • We have had, and may in the future have, disagreements with certain host governments and contractual counterparties regarding certain of our rights and responsibilities.
  • The geographic locations of our licenses in Africa and the Gulf of America subject us to a risk of loss of revenue or curtailment of production from factors specifically affecting those areas.
  • Risks Relating to our Business and Financial Condition
  • A substantial or extended decline in both global and local oil, natural gas and LNG prices may adversely affect our business, financial condition and results of operations.
  • Our business plan requires substantial additional capital, which we may be unable to raise on acceptable terms or at all in the future, which may in turn limit our ability to develop our exploration, appraisal, development and production activities.
  • We may be required to take write‑downs of the carrying values of our oil and natural gas assets due to decreases in the estimated future net cash flows from our operations, which may occur as a result of decreases in oil, natural gas, and LNG prices, poor field performance, increased expenditures or changes in the timing or amount of investment, among other things, and such decreases could result in reduced availability under our commercial debt facility.
  • We face various risks associated with increased activism against, or change in public sentiment for, oil and gas exploration development, and production activities and ESG considerations, including climate change and the transition to a lower carbon economy.
  • Outbreaks of disease may adversely affect our business operations and financial condition.
  • Deterioration in the credit or equity markets could adversely affect us.
  • We may incur substantial losses and become subject to liability claims as a result of future oil and natural gas operations, for which we may not have adequate insurance coverage.
  • Slower global economic growth rates may materially adversely impact our operating results and financial position.
  • Increased costs and availability of capital could adversely affect our business.
  • Our derivative activities could result in financial losses or could reduce our income.
  • Our commercial debt facility, GoA Term Loan Facility, the bond terms governing our GTA Nordic bonds and the indentures governing our Senior Notes and Convertible Senior Notes contain certain covenants that may inhibit our ability to make certain investments, incur additional indebtedness and engage in certain other transactions, which could adversely affect our ability to meet our future goals.
  • Provisions of our Senior Notes and Convertible Senior Notes could discourage an acquisition of us by a third-party.
  • Our level of indebtedness may increase and thereby reduce our financial flexibility.
  • We are a holding company and our ability to make payments on our outstanding indebtedness, including our Senior Notes and Convertible Senior Notes, is dependent upon the receipt of funds from our subsidiaries by way of dividends, fees, interest, loans or otherwise.
  • We may be subject to risks in connection with acquisitions and the integration of acquisitions may be difficult.
  • If we fail to realize the anticipated benefits of acquisitions, our results of operations may be adversely affected.
  • A cybersecurity incident, including a breach of digital security, could result in information theft, data corruption, operational disruption, and/or financial loss.
  • We are incorporating artificial intelligence technologies into our processes and these technologies may present business, operational, compliance, cybersecurity, and reputational risks.
  • Our ability to utilize net operating loss carryforwards may be subject to certain limitations.
  • Risks Relating to Regulation
  • Our business, operations and financial condition may be directly and indirectly adversely affected by political, economic, and environmental circumstances, and changes in laws and regulations, in the countries and regions in which we operate.
  • More comprehensive and stringent regulation in the Gulf of America has materially increased costs and delays in offshore oil and natural gas exploration and production operations.
  • The oil and gas industry, including the acquisition of exploratory licenses, is intensely competitive and many of our competitors possess and employ substantially greater resources than us.
  • Participants in the oil and gas industry are subject to numerous laws, regulations, and other legislative instruments that can affect the cost, manner or feasibility of doing business.
  • We are subject to numerous health, safety and environmental laws and regulations which may result in material liabilities and costs.
  • We may be exposed to assertions concerning or liabilities under the U.S. Foreign Corrupt Practices Act and other anti‑corruption laws, and any such assertions or determination that we violated the U.S. Foreign Corrupt Practices Act or other such laws could result in significant costs to Kosmos and have a material adverse effect on our business.
  • Federal regulatory law could have an adverse effect on our ability to use derivatives to reduce the effect of commodity price, interest rate and other risks associated with our business.
  • General Risk Factors
  • We are dependent on certain members of our management and technical team.
  • We operate in a litigious environment.
  • We face various risks associated with global activism.
  • Our share price may be volatile, and purchasers of our common stock could incur substantial losses.
  • Holders of our common stock will be diluted if additional shares are issued.

Legal proceedings

From time to time, we may be involved in various legal and regulatory proceedings arising in the normal course of business. While we cannot predict the occurrence or outcome of these proceedings with certainty, management believes that the likelihood of an unfavorable outcome in any pending legal or regulatory proceeding having a material impact, individually or in the aggregate, is neither reasonably possible nor probable of occurring.
