Current report

We are incorporating artificial intelligence technologies into our processes and these technologies may present business, operational, compliance, cybersecurity, and reputational risks.

Current report

Our business increasingly utilizes artificial intelligence (“AI”), machine learning, and automated decision making to improve our internal processes and support operational and strategic decisions. The development, deployment and use of these technologies, combined with an evolving and uncertain regulatory environment, may result in new or heightened governmental or regulatory scrutiny, litigation, confidentiality or security risks, reputational harm, liability or other adverse consequences to our business operations, any of which could adversely affect our business, financial condition and results of operations.

Current report

The use of AI tools can lead to unintended consequences, including the unauthorized use or disclosure of confidential and proprietary information, or the generation of content or outputs that appear correct but are factually inaccurate, misleading, or otherwise flawed. Reliance on such outputs could expose us to risks related to inaccuracies or errors in the output of such technologies. We have established an internal, cross-functional AI committee to oversee and guide our AI strategy including evaluating the costs, benefits, risks, and opportunities associated with the use of AI tools in our business and recommending mitigation measures, as well as developing and implementing an AI use policy across the Company. However, these governance measures may not be effective in all cases, and it is not possible to predict or prevent all of the risks related to the use of AI, machine learning, and automated decision making technologies. In addition, future changes in laws or developments in the regulatory frameworks governing the use of such technologies and in related stakeholder expectations could restrict or limit our use of AI, increase our compliance costs, or subject us to liability, any of which could adversely affect our ability to develop and use such technologies.

Current report

In addition to the array of new or revised safety, permitting and certification requirements developed and implemented by the DOI in recent years, there have been a variety of proposals and initiatives to change existing laws, regulations and agency practices that could affect offshore development and production, such as, for example, proposals to increase or otherwise revise the minimum financial responsibility or other security required under the Oil Pollution Act of 1990 or otherwise applicable to offshore lessees and operators. Regulatory initiatives relating to financial assurance, bonding and other forms of security continue to evolve. For example, in 2024, the DOI finalized an offshore financial assurance rule that increased bonding and other financial responsibility requirements for certain offshore lessees and operators. In 2025, the DOI announced plans to revise this rule as part of a broader review of offshore financial assurance requirements. Any changes to the rule, or uncertainty regarding its implementation, could affect our financial assurance obligations, compliance costs and offshore development activities.

Current report

From time to time, we are involved in litigation, regulatory examinations and administrative proceedings primarily arising in the ordinary course of our business in jurisdictions in which we do business. Although the outcome of these matters cannot be predicted with certainty, management believes that the likelihood of an unfavorable outcome having a material impact is neither reasonably possible nor probable of occurring

Previous report

Additionally, the future exploitation and sale of associated and non‑associated natural gas and liquids and LNG will be subject to timely commercial processing and marketing of these products, which depends on the contracting, financing, building and operating of infrastructure by third parties. For example, we transport and process natural gas from the Jubilee and TEN Fields to mainland Ghana through a pipeline and processing facilities that are controlled by the Government of Ghana. We cannot provide any assurance about uptime and availability of the pipeline and processing facilities. In addition, during 2023, the Jubilee partners reached an interim agreement to sell Jubilee Field gas to the Government of Ghana through May 2024. This interim gas sales agreement was subsequently extended to November 2025 while the partners continue on-going discussions with the Government of Ghana regarding a long-term future gas sales agreement. If the interim gas sales agreement is not extended again or a long-term gas sales agreement in Ghana is not approved, our ability to continuously extract and process natural gas may be harmed and we may be required to re-inject or flare such natural gas in order to maintain crude oil production and or reduce our overall crude oil production, which may adversely impact our results of operations, financial condition and prospects.

Previous report

As an example, multiple discovered fields and a significant portion of our proved reserves are located offshore Ghana. The WCTP petroleum contract, the DT petroleum contract and the Jubilee UUOA cover the two blocks and the Jubilee and TEN Fields that form the basis of our current operations in Ghana. Pursuant to these petroleum contracts, most significant decisions, including our plans for development and annual work programs, must be approved by GNPC, the Petroleum Commission and/or Ghana’s Ministry of Energy. We have previously had disagreements with the Ministry of Energy, GNPC, and the Ghana Revenue Authority (the “GRA”) regarding certain of our rights and responsibilities under these petroleum contracts, the 1984 Ghanaian Petroleum Law and the Internal Revenue Act, 2000 (Act 592) (the “Ghanaian Tax Law”). For example, these included disagreements over sharing information with prospective purchasers of our interests, pledging our interests to finance our development activities, potential liabilities arising from discharges of small quantities of drilling fluids into Ghanaian territorial waters, the failure to approve the proposed sale of our Ghanaian assets, assertions that could be read to give rise to taxes or other payments payable under the Ghanaian Tax Law, failure to approve PoDs relating to certain discoveries offshore Ghana and the relinquishment of certain exploration areas on our licensed blocks offshore Ghana. The resolution of certain of these disagreements required us to pay agreed settlement costs to GNPC and/or the Government of Ghana. In Ghana, as part of its normal course audit process the GRA has asserted that we have underpaid certain tax and other contractual fiscal obligations. We believe that these claims are without merit and we intend to vigorously dispute them if necessary, but there can be no assurance regarding the resolution of these or future disagreements.

Previous report

For example, former President Biden signed an executive order on January 20, 2021, titled “Executive Order on Protecting Public Health and the Environment and Restoring Science to Tackle the Climate Crisis”, which among other things called for a review of regulations and other executive actions promulgated, issued or adopted during the first Trump Administration to assess whether they were, in the view of the Biden Administration, sufficiently protective of public health and the environment, including with respect to climate change, and consistent with science. While these executive orders, should they remain in place, may increase our compliance costs, restrict our access to additional acreage and new leases, lead to limitations or delays on our ability to secure additional permits or otherwise lead to limitations on the scope of our operations, President Trump has indicated that a priority of his incoming administration would be to increase the domestic production of fossil fuels, and reverse many of the Biden Administration’s environmental policies. As such, the potential impacts of these Biden Administration executive orders on our future consolidated financial condition, results of operations or cash flows cannot currently be predicted.

Previous report

In addition, we are subject to uncertainties surrounding the economies and fiscal health of the countries in which we operate. For example, the Republic of Ghana was subject to ratings downgrades on its sovereign debt in 2022 and 2023. In May 2023, the International Monetary Fund Executive Board approved a $3.0 billion, 3-year extended credit facility arrangement to support Ghana’s economic recovery program, and the Ghanaian authorities have since made progress on their comprehensive debt restructuring. Ratings downgrades such as this one in Ghana have affected the Company’s own credit ratings due to concerns over revenue dependence on a single country. A significant reduction in the availability of credit could materially and adversely affect our ability to achieve our planned growth and operating results.

Previous report

For example, Ghana’s Parliament has enacted the Petroleum Revenue Management Act, the Petroleum Commission Act of 2011, and the 2016 Ghanaian Petroleum Law. There can be no assurance that these laws will not seek to retroactively, either on their face or as interpreted, modify the terms of the agreements governing our license interests in Ghana, including the WCTP and DT petroleum contracts and the Jubilee UUOA, require governmental approval for transactions that effect a direct or indirect change of control of our license interests or otherwise affect our current and future operations in Ghana. Any such changes may have a material adverse effect on our business. We also cannot assure you that government approval will not be needed for direct or indirect transfers of our petroleum agreements or interests thereunder based on existing legislation.

Previous report

From time to time, we may become involved in various legal and regulatory proceedings arising in the normal course of business. We cannot predict the occurrence or outcome of these proceedings with certainty, and if we are unsuccessful in these disputes and any loss exceeds our available insurance, this could have a material adverse effect on our results of operations.

Under certain petroleum contracts, we have work commitments to perform exploration and other related activities. Failure to do so may result in our loss of the licenses. As of December 31, 2024, we have unfulfilled drilling obligations for one development well in Equatorial Guinea. In certain other petroleum contracts, we are in the initial exploration phases, some of which have certain obligations that have yet to be fulfilled. Over the course of the next several years, we may choose to enter into the next phase of those petroleum contracts which will likely include firm obligations to drill wells. Failure to execute our obligations may result in our loss of the licenses.

Current wording

Under certain petroleum contracts, we have work commitments to perform exploration and other related activities. Failure to do so may result in our loss of the licenses. As of December 31, 2025, we have a commitment to one development well in Equatorial Guinea. Additionally, as part of the recent extension of the Petroleum Agreements covering the Jubilee and TEN fields, the Jubilee plan of development is amended to include up to twenty additional wells in the field, with a commitment to drill a minimum of ten additional wells. In certain other petroleum contracts, we are in the initial exploration phases, some of which have certain obligations that have yet to be fulfilled. Over the course of the next several years, we may choose to enter into the next phase of those petroleum contracts which will likely include firm obligations to drill wells. Failure to execute our obligations may result in our loss of the licenses.

Previous wording

The interests in and development of the Jubilee Field are governed by the terms of the Jubilee UUOA. The parties to the Jubilee UUOA, the collective interest holders in each of the WCTP and DT Blocks, initially agreed that interests in the Jubilee Unit will be shared equally, with each block deemed to contribute 50% of the area of such unit. The respective interests in the Jubilee Unit were therefore initially determined by the respective interests in such contributed block interests. Pursuant to the terms of the Jubilee UUOA, the percentage of such contributed interests is subject to a process of redetermination once sufficient development work has been completed in the unit. The initial redetermination process was completed on October 14, 2011. As a result of the initial redetermination process, the tract participation was determined to be 54.4% for the WCTP Block and 45.6% for the DT Block. Consequently, our Unit Interest (participating interest in the Jubilee Unit) was increased from

The respective interests in the Jubilee Unit were therefore initially determined by the respective interests in such contributed block interests. Pursuant to the terms of the Jubilee UUOA, the percentage of such contributed interests is subject to a process of redetermination. Following an initial redetermination process completed on October 14, 2011, the tract participation was determined to be 54.4% for the WCTP Block and 45.6% for the DT Block. Consequently, our Unit Interest (participating interest in the Jubilee Unit) was increased from 23.5% to 24.1% upon completion of the initial redetermination process. Following the acquisition of Anadarko WCTP Company in October 2021 and completion of the subsequent pre-emption by Tullow in March of 2022, Kosmos’ interest in the Jubilee Unit Area now stands at 38.6%. An additional redetermination could occur sometime if requested by a party that holds greater than a 10% interest in the Jubilee Unit. We cannot assure you that any redetermination pursuant to the terms of the Jubilee UUOA will not negatively affect our interests in the Jubilee Unit or that such redetermination will be satisfactorily resolved.

Previous wording

In Ghana, we currently produce associated gas from the Jubilee and TEN Fields. A gas pipeline from the Jubilee Field transports such natural gas onshore for processing and sale. We granted the Government of Ghana the first 200 Bcf of natural gas exported from the Jubilee Field to shore at zero cost. As of January 1, 2023, the Jubilee partners had fulfilled this commitment. During 2023, the Jubilee partners reached an interim agreement to sell Jubilee Field gas to the Government of Ghana through May 2024. This interim gas sales agreement was subsequently extended to November 2025 while the partners continue on-going discussions with the Government of Ghana regarding a long-term future gas sales agreement. If the interim gas sales agreement is not extended again or a long-term gas sales agreement in Ghana is not approved, we may not be able to commercialize our natural gas resources in Jubilee. Our inability to export associated natural gas from the Jubilee Field could eventually impact our oil production and could cause us to re-inject or flare any natural gas we cannot export.

During 2023, the Jubilee partners reached an interim agreement to sell Jubilee Field gas to the Government of Ghana through May 2024. This interim gas sales agreement was subsequently extended to November 2025 at a price of approximately $3.00 per MMBtu. In December 2025, as part of the extension of the WCTP and DT Petroleum Agreements, the Ghana partners and Government of Ghana have approved an amended gas sales agreement at a price of $2.50 per MMBtu through the extended expiration date of 2040 for the WCTP and DT licenses. Our inability to export associated natural gas from the Jubilee Field could eventually impact our oil production and could cause us to re-inject or flare any natural gas we cannot export.

Previous wording

In Mauritania and Senegal, we plan to export the majority of our gas resource to the LNG market. However, that plan is contingent on making additional final investment decisions on our gas discoveries and constructing the necessary infrastructure to produce, liquefy and transport the gas to the market. Additionally, such plans are contingent upon receipt of required partner and government approvals.

Current wording

In Mauritania and Senegal, while we currently only export our gas resource to the LNG market, we also intend to utilize existing facilities for domestic gas delivery. This plan is contingent signing gas sales agreements for domestic gas and the necessary infrastructure to transport the gas to domestic onshore markets being constructed. Additionally, such plans are contingent upon receipt of required partner and government approvals.

Previous wording

Our ability to market our oil and natural gas production will depend substantially on the availability and capacity of processing facilities, oil and LNG tankers and other infrastructure, including FPSOs, owned and operated by third parties. Our failure to obtain such facilities on acceptable terms could materially harm our business. We also rely on continuing access to drilling rigs and construction vessels suitable for the environment in which we operate. The delivery of drilling rigs or construction vessels may be delayed or cancelled, and we may not be able to gain continued access to suitable rigs or vessels in the future. We may be required to shut in oil and natural gas wells because of the absence of a market or because access to processing facilities may be limited or unavailable. If that were to occur, then we would be unable to realize revenue from those wells until arrangements were made to deliver the production to market, which could cause a material adverse effect on our financial condition and results of operations. In addition, the shutting in of wells can lead to mechanical problems upon bringing the production back online, potentially resulting in decreased production and increased remediation costs.

Furthermore, the marketability of expected oil and natural gas production from our discoveries and prospects will also be affected by numerous factors. These factors include, but are not limited to, market fluctuations of prices (such as recent significant variations in oil, natural gas and LNG prices), proximity, capacity and availability of drilling rigs and related equipment, qualified personnel and support vessels, processing facilities, transportation vehicles and pipelines, equipment availability, access to markets and government regulations (including, without limitation, regulations relating to prices, taxes, royalties, allowable production, domestic supply requirements, importing and exporting of oil and natural gas, the ability to flare or vent natural gas, health and safety matters, environmental protection and climate change). The effect of these factors, individually or jointly, may result in us not receiving an adequate return on invested capital.

The prices that we will receive for our oil, natural gas, and LNG will significantly affect our revenue, profitability, access to capital and future growth rate. Historically, the oil and natural gas markets have been volatile and will likely continue to be volatile in the future. Oil, natural gas and LNG prices experienced significant volatility in the past few years and will likely continue to be volatile in the future. For example, Russia’s continued war in Ukraine, ongoing instability in the Middle East, a potential regional or global recession, inflationary pressures and other varying macroeconomic conditions and the effects on demand for oil and natural gas has resulted in significant variations in oil, natural gas and LNG prices. The prices that we will receive for our production and the levels of our production depend on numerous factors. These factors include, but are not limited to, the following:

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.

Previous wording

Significant outbreaks of contagious diseases, and other adverse public health developments, could have a material impact on our business operations and financial condition. Many of our operations are currently, and will likely remain in the near future, in developing countries which are susceptible to outbreaks of disease and may lack the resources to effectively contain such an outbreak quickly. Such outbreaks may impact our ability to explore for oil and gas, develop or produce our license areas by limiting access to qualified personnel, increasing costs associated with ensuring the safety and health of our personnel, restricting transportation of personnel, equipment, supplies and oil and gas production to and from our areas of operation and diverting the time, attention and resources of government agencies which are necessary to conduct our operations. In addition, any losses we experience as a result of such outbreaks of disease which impact sales or delay production may not be covered by our insurance policies.

Current wording

Significant outbreaks of contagious diseases such as COVID-19, and other adverse public health developments, could have a material impact on our business operations and financial condition. Many of our operations are currently, and will likely remain in the near future, in developing countries which are susceptible to outbreaks of disease, such as the Ebola virus disease, and may lack the resources to effectively contain such an outbreak quickly. Such outbreaks may impact our ability to explore for oil and gas, develop or produce our license areas by limiting access to qualified personnel, increasing costs associated with ensuring the safety and health of our personnel, restricting transportation of personnel, equipment, supplies and oil and gas production to and from our areas of operation and diverting the time, attention and resources of government agencies which are necessary to conduct our operations. In addition, any losses we experience as a result of such outbreaks of disease which impact sales or delay production may not be covered by our insurance policies.

Previous wording

For example, an epidemic of the Ebola virus disease occurred in parts of West Africa in 2014 and continued through 2015. A substantial number of deaths were reported by the World Health Organization (“WHO”) in West Africa, and the WHO declared it a global health emergency. Likewise, the global spread of the COVID-19 pandemic resulted in travel restrictions, “shelter-in-place” and various quarantine measures and other governmental actions taken to inhibit its spread and created significant volatility, uncertainty and economic disruption in the markets in which we operate, which affected our business and operations and those of our suppliers, contractors and partners. It is impossible to predict the effect and potential spread of new outbreaks of the Ebola virus or other viruses in West Africa and surrounding areas. Should another Ebola or other virus outbreak occur, including to the countries in which we operate, or not be satisfactorily contained, our exploration, development and production plans for our operations could be delayed, or interrupted after commencement. Any changes to these operations could significantly increase costs of operations. Our operations require contractors and personnel to travel to and from Africa as well as the unhindered transportation of equipment and oil and gas production (in the case of our producing fields). Such operations also rely on infrastructure, contractors and personnel in Africa. If travel bans are implemented or extended to the countries in which we operate, or contractors or personnel refuse to travel there, we could be adversely affected. If services are obtained, costs associated with those services could be significantly higher than planned which could have a material adverse effect on our business, results of operations, and future cash flow. In addition, should an Ebola or other virus outbreak spread to the countries in which we operate, access to the FPSOs could be restricted and/or terminated. The FPSOs are potentially able to operate for a short period of time without access to the mainland, but if restrictions extended for a longer period we and the operator of the impacted fields would likely be required to cease production and other operations until such restrictions were lifted.

Our commercial debt facility requires us to maintain certain financial ratios, such as debt service coverage ratios and cash flow coverage ratios. All of these restrictive covenants may limit our ability to move funds among our subsidiaries, operate our business, or expand or pursue our business strategies. Our ability to comply with these and other provisions of our commercial debt facility and the indentures governing our Senior Notes and Convertible Senior Notes may be impacted by changes in economic or business conditions, our results of operations or events beyond our control. The breach of any of these covenants could result in a default under our commercial debt facility and the indentures governing our Senior Notes and Convertible Senior Notes, in which case, depending on the actions taken by the lenders thereunder or their successors or assignees, such lenders could elect to declare all amounts borrowed under such debt instruments, together with accrued interest, to be due and payable. If we were unable to repay such borrowings or interest, our lenders, successors or assignees could proceed against their collateral. If the indebtedness under our commercial debt facility and the indentures governing our Senior Notes and Convertible Senior Notes were to be accelerated, our assets may not be sufficient to repay in full such indebtedness. In addition, the limitations imposed by such debt instruments on our ability to incur additional debt and to take other actions might significantly impair our ability to obtain other financing.

Our ability to use our federal net operating losses to offset potential future taxable income and related income taxes that would otherwise be due is dependent upon our generation of future taxable income and we cannot predict with certainty when, or whether, we will generate sufficient taxable income to use all of our net operating losses. In addition, Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”), contains rules that impose an annual limitation on the ability of a company with federal net operating loss carryforwards that undergoes an ownership change, which is generally any change in ownership of more than 50% of its stock (by value) over a three-year period, to utilize its federal net operating loss carryforwards in years after the ownership change. These rules generally operate by focusing on ownership changes among holders owning directly or indirectly 5% or more of the shares of stock of a company or any change in ownership arising from a new issuance of shares of stock by such company.

Our ability to use our federal and international net operating losses to offset potential future taxable income and related income taxes that would otherwise be due is dependent upon our generation of future taxable income and we cannot predict with certainty when, or whether, we will generate sufficient taxable income to use all of our net operating losses. In addition, with regard to our U.S. net operating losses only, Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”), contains rules that impose an annual limitation on the ability of a company with federal net operating loss carryforwards that undergoes an ownership change, which is generally any change in ownership of more than 50% of its stock (by value) over a three-year period, to utilize its federal net operating loss carryforwards in years after the ownership change.

In addition, we are subject both to uncertainties in the application of the tax laws in the countries in which we operate and where we are resident for tax purposes and to possible changes in such tax laws (or the application thereof), each of which could result in an increase in our tax liabilities. These risks may be higher in the developing countries in which we conduct a majority of our activities, as is the case in Ghana, where the GRA has disputed certain tax deductions we had claimed in prior fiscal years’ Ghanaian tax returns as non‑allowable under the terms of the Ghanaian Petroleum Income Tax Law, as well as non‑payment of certain transactional taxes, contractual fiscal obligations and other payments. We have faced, and continue to face, similar tax related disputes with the Senegal, Mauritania, and Equatorial Guinea Tax Administrations.

In the Gulf of America, regulatory initiatives are continually developed and implemented at the federal level to prevent major well control incidents. The Department of Interior (“DOI”) through the BOEM and the Bureau of Safety and Environmental Enforcement (“BSEE”), has issued a variety of regulations and Notices to Lessees and Operators (“NTLs”), intended to impose additional safety, permitting and certification requirements applicable to exploration, development and production activities in the Gulf of America. These regulatory initiatives effectively slowed down the pace of drilling and production operations in the Gulf of America as adjustments were being made in operating procedures, certification requirements and lead times for inspections, drilling applications and permits, and exploration and production plan reviews, and as the federal agencies evolved into their present-day bureaus. On May 15, 2019, BSEE published a final rule with an effective date of July 15, 2019 that revises requirements for well design, well control, casing, cementing, real-time monitoring (RTM), and subsea containment. These revisions modify regulations pertaining to offshore oil and gas drilling, completions, workovers, and decommissioning in accordance with Executive and Secretary of the Interior's Orders. Key features of the well control regulations include requirements for blowout preventers (BOPs), double shear rams, third-party reviews of equipment, real time monitoring data, safe drilling margins, centralizers, inspections and other reforms related to well design and control, casing, cementing and subsea containment. For a discussion of recent drilling and climate change executive orders signed by former President Biden and the potential impact of the new Trump Administration on these orders, see the risk factor earlier in this 10-K titled “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.”

These regulatory initiatives have, at various times, effectively slowed down the pace of drilling and production operations in the Gulf of America as adjustments were being made in operating procedures, certification requirements and lead times for inspections, drilling applications and permits, and exploration and production plan reviews, and as the federal agencies evolved into their present-day bureaus.

In addition to the array of new or revised safety, permitting and certification requirements developed and implemented by the DOI in the past few years, there have been a variety of proposals to change existing laws and regulations that could affect offshore development and production, such as, for example, a proposal to significantly increase the minimum financial responsibility demonstration required under the Oil Pollution Act of 1990. To the extent the existing regulatory initiatives implemented and pursued over the past few years or any future restrictions, whether through legislative or regulatory means or increased or broadened permitting and enforcement programs, foster uncertainties or delays in our offshore oil and natural gas development or exploration activities, then such conditions may have a material adverse effect on our business, financial condition and results of operations. Any other new rules, regulations or legal initiatives by BOEM or other governmental authorities that impose more stringent requirements regarding financial assurances, moratoria on new leases or otherwise adversely affecting our offshore activities could result in increased costs, limit our operations and adversely impact our future financial results.

In addition, we expect continuing attention to climate change and energy transition issues. For example, in April 2016, 195 nations, including Ghana, Mauritania, Sao Tome and Principe, Senegal and the United States, signed and officially entered into an international climate change accord (the “Paris Agreement”). The Paris Agreement calls for signatory countries to set their own GHG emissions targets, make these emissions targets more stringent over time and be transparent about the GHG emissions reporting and the measures each country will use to achieve its GHG targets. A long-term goal of the Paris Agreement is to limit global temperature increase to well below two degrees Celsius from temperatures in the pre-industrial era. President Trump has indicated that he intends to withdraw the United States from the Paris Agreement, as he did during his first term. Separately, in December 2023, the U.S. EPA announced its final rule regulating methane and volatile organic compounds emissions in the oil and gas industry which, among other things, requires periodic inspections to detect leaks (and subsequent repairs), places stringent restrictions on venting and flaring of methane, and establishes a program whereby third parties can monitor and repot large methane emissions to the EPA. Relatedly, in November 2024, the U.S. EPA finalized a rule implementing the Waste Emissions Charge, a fee for large emitters of methane if their emissions exceed certain levels, as required by the Inflation Reduction Act. In addition, in March 2024, the SEC finalized rules requiring disclosure of a range of climate change-related information, including, among other things, companies’ climate change risk management; material climate-related financial risks; and disclosure of material Scope 1 and Scope 2 emissions. While implementation of the rules could be costly and time consuming, litigation challenging the rules has commenced, and the SEC has stayed the rules pending this litigation; in addition, President Trump criticized these rules during his campaign, and it is expected that his administration could take steps to undo them. It cannot be determined at this time what effect these various climate change and GHG emissions-related developments will have on our business, results of operations and financial condition. This legislative and regulatory uncertainty, however, could result in a disruption to our business or operations. For a discussion of environmental and climate change executive orders signed by former President Biden and the potential impact of the Trump Administration on these orders, see the risk factor earlier in this 10-K titled “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.”

We are subject to the U.S. Foreign Corrupt Practices Act (“FCPA”) and other laws that prohibit improper payments or offers of payments to foreign government officials and political parties for the purpose of obtaining or retaining business or otherwise securing an improper business advantage. In addition, the United Kingdom has enacted the Bribery Act of 2010, and we may be subject to that legislation under certain circumstances. We do business and may do additional business in the future in countries and regions in which we may face, directly or indirectly, corrupt demands by officials. We face the risk of unauthorized payments or offers of payments by one of our employees, contractors or consultants. Our existing safeguards and any future improvements may prove to be less than effective in preventing such unauthorized payments, and our employees and consultants may engage in conduct for which we might be held responsible. Violations of the FCPA or other anti-corruption laws may result in severe criminal or civil sanctions, and we may be subject to other liabilities, which could negatively affect our business, operating results and financial condition. In addition, the U.S. government may seek to hold us liable for successor liability for FCPA violations committed by companies in which we invest in (for example, by way of acquiring equity interests in, participating as a joint venture partner with, acquiring the assets of, or entering into certain commercial transactions with) or that we acquire.

23.5% to 24.1% upon completion of the initial redetermination process. Following the acquisition of Anadarko WCTP Company, which owned a participating interest in the WCTP Block and DT Block, our Unit Interest (participating interest in the Jubilee Unit) increased from 24.1% to 42.1%. Following the completion of the pre-emption by Tullow in March of 2022, Kosmos’ interest in the Jubilee Unit Area decreased from 42.1% to 38.6%. An additional redetermination could occur sometime if requested by a party that holds greater than a 10% interest in the Jubilee Unit. We cannot assure you that any redetermination pursuant to the terms of the Jubilee UUOA will not negatively affect our interests in the Jubilee Unit or that such redetermination will be satisfactorily resolved.
