LETTER TO STOCKHOLDERS
April 8, 2022

Dear Marathon Oil Corporation Stockholder,

2021 was an outstanding year at Marathon Oil, as evidenced by our bottom line financial results and environmental, safety and governance (ESG) excellence that compete not only with the best companies in energy, but with the best in the S&P 500.
We’re particularly proud of our strong safety performance, disciplined capital framework and compelling return of capital to stockholders, including executing over $1 billion of share repurchases since October and four consecutive base dividend raises, representing a cumulative 133% increase.
ltmdv4a.jpg
Throughout the year, we did not waver from our reinvestment rate capital allocation framework, generating over $2.2 billion of free cash flow, including approximately $900 million during fourth quarter alone, and returning that cash back to you, our stockholders. During fourth quarter, we returned more than 70% of our cash flow from operations to equity investors, significantly exceeding our minimum 40% commitment.
Marathon Oil believes continuously improving all elements of our ESG performance is foundational to maximizing long-term stockholder value. During 2021, we made remarkable progress toward our ESG objectives, including achieving our 30% greenhouse gas (GHG) intensity reduction target and improving total Company gas capture to 98.8%. In early 2022, we announced new environmental objectives that complement our existing 2025 GHG intensity goal, and which are consistent with the trajectory of the Paris Climate Agreement. Ultimately, we believe these new quantitative objectives highlight our commitment to meeting global energy demand with leading environmental performance.
Your Board of Directors and management cordially invite you to attend our 2022 Annual Meeting of Stockholders, to be held May 25, 2022, in the Level 6 Auditorium of One MRO, 990 Town & Country Blvd., Houston, TX 77024, at 10:00 a.m. Central Time. In the event it is not possible or advisable to hold our Annual Meeting in person because of the COVID-19 pandemic, we will announce alternative arrangements for the meeting as promptly as practicable, which may include holding the meeting virtually. If we take this step, we will announce the decision to do so in advance.
We value the communication we have established with our stockholders. We look forward to continuing to hear your views, and we ask for your continued support as we work to maximize the value of your investment in our Company.
We are making our proxy materials accessible online, which allows us to provide our stockholders with the information they need, while lowering the costs of delivery and reducing the environmental impact of our Annual Meeting. Please read the Proxy Statement for more information about how to access the proxy materials online.
On April 13, 2022, we plan to mail to our U.S. stockholders a notice explaining how to access our 2022 Proxy Statement and 2021 Annual Report, request a printed copy of these materials and vote online. All other stockholders will continue to receive copies of the Proxy Statement and Annual Report by mail.
Your vote is important. Whether or not you plan to attend the meeting, we encourage you to vote promptly so that your shares will be represented and properly voted at the meeting.
Sincerely,

FOCUS ON HEALTH, ENVIRONMENTAL, SAFETY
AND CORPORATE RESPONSIBILITY
Our Board of Director’s (Board) key oversight role includes reviewing and aligning on corporate strategy, financial integrity and overseeing the sustainability of our enterprise and the strength of our risk management efforts. Our Board believes we have a responsibility to deliver long-term value to our stockholders, while also providing affordable and reliable energy in a responsible, safe and sustainable manner, and their decision-making takes climate-related risks into account. Our Board has four standing committees that assist with various aspects of this oversight: Audit and Finance; Compensation; Corporate Governance and Nominating; and Health, Environmental, Safety and Corporate Responsibility (HESCR). The HESCR Committee plays a vital role in our sustainability efforts and includes directors with experience in this area. One of the principal functions of the HESCR Committee is to identify, evaluate and monitor: (i) safety, (ii) health, environmental and climate issues, (iii) social, public policy and political trends and (iv) issues and concerns that could affect our business activities and performance. This committee meets at least twice per year to understand and monitor climate-

related trends, issues, legislation, policies, practices and concerns. The Compensation Committee also ensures that our sustainability focus carries through certain components of our compensation structure. In 2021, the annual cash bonus incentive program approved by the Compensation Committee included safety and environmental performance metrics and objectives. See “Corporate Governance—Health, Environmental, Safety and Corporate Responsibility” for additional information.
FOCUS ON HUMAN CAPITAL MANAGEMENT
Our Board believes talent is one of the critical capabilities foundational to delivering on our corporate strategy. Intentional human capital management strategies enable us to attract, develop, retain and reward our dedicated employees. Our Vice President of Human Resources has leadership accountability for our workforce management policies and programs and reports directly to our CEO. Our Board provides oversight to our human capital management strategies as an integral part of our overall enterprise risk management process. Due to the importance of our workforce capabilities, the Board receives updates on our human capital management on a regular cadence.

PROPOSAL 1: ELECTION OF DIRECTORS
Under our Restated Certificate of Incorporation, directors are elected for terms expiring at the next succeeding Annual Meeting of stockholders. We currently have 8 directors whose terms expire in 2022. Jason B. Few is not seeking reelection and his service will end at the Annual Meeting on May 25, 2022, at which time our Board will be set to seven (7) directors. Each director is nominated for a one-year term expiring at the 2023 Annual Meeting.
Directors are elected by a majority of votes cast. For a director to be elected, the number of shares cast “FOR” a director must exceed the number of votes cast “AGAINST” that director. Abstentions will have no effect in director elections. If any nominee for whom you have voted becomes unable to serve, your proxy may be voted for another person designated by our Board.
Our By-laws require any incumbent who does not receive sufficient votes to promptly tender his or her resignation to our Board. Our Corporate Governance and Nominating Committee will recommend to our Board whether to accept or reject the tendered resignation or take other action. Our Board will act on the tendered resignation, taking into account the Corporate Governance and Nominating Committee’s recommendation, and publicly disclose its decision regarding the tendered resignation within 90 days after certification of the election results. In the event of a vacancy, our Board may fill the position or decrease the size of our Board.
DIRECTOR QUALIFICATIONS AND NOMINATIONS
Our Corporate Governance Principles set forth the process for director selection and director qualifications. In summary, the chair of the Corporate Governance and Nominating Committee, the CEO and the Secretary of the Company work, often with a third-party professional search firm, to review director candidates and their credentials when the Board believes there is a need. At least one member of the Corporate Governance and Nominating Committee, the Independent Lead Director and the CEO meet with the potential director candidate. This screening process applies to nominees recommended by the Corporate Governance and Nominating Committee, as well as nominees recommended by our stockholders in accordance with our By-laws or applicable law. Once a director has been selected either by our Board to serve until the next annual meeting or by election at the annual meeting, they undergo orientation and training. The Corporate Governance and Nominating Committee is responsible for reviewing with our Board the appropriate skills and characteristics required of directors. Directors should be individuals of substantial accomplishment with demonstrated leadership capabilities, and they should represent all stockholders rather than any special interest group or constituency. Selection of director nominees includes a consideration of numerous skills and qualifications, including:
»    an evaluation of their independence;
»    their business or professional experience;
»    their integrity and judgment;
»    their record of public service;
»    their ability to devote sufficient time to the affairs of the Company;
»    their diversity, including diversity of backgrounds and experience they will bring to our Board; and
»    the Company’s needs at that particular time.
DIRECTOR INDEPENDENCE
All of our directors, other than our CEO, are independent.  In accordance with applicable laws, regulations, our Corporate Governance Principles and the rules of the New York Stock Exchange (NYSE), the Board must affirmatively determine the independence of each director and director nominee. The Corporate Governance and Nominating Committee considers all relevant facts and circumstances including, without limitation, transactions during the previous year between the Company and the director directly, immediate family

5 MARATHON OIL | PROPOSAL 1: ELECTION OF DIRECTORS


members of the director, organizations with which the director is affiliated and the frequency and dollar amounts associated with these transactions. The Corporate Governance and Nominating Committee further considers whether the transactions were at arm’s length in the ordinary course of business and whether the transactions were consummated on terms and conditions similar to those of unrelated parties. The Corporate Governance and Nominating Committee then makes a recommendation to the Board with respect to the independence of each director and director nominee.
As part of the determination, the Corporate Governance and Nominating Committee and the Board considered that certain of the directors serve or previously served together on not-for-profit boards of charitable organizations and that the Company made various contributions to certain charitable organizations that the directors are associated with. The Board also took into account that certain entities affiliated or previously affiliated with the directors received payments or paid amounts to the Company in ordinary course business transactions that were at arm’s length.
Based on these considerations, the standards in our Corporate Governance Principles and the recommendation of the Corporate Governance and Nominating Committee, the Board determined that Chadwick C. Deaton, Marcela E. Donadio, Jason B. Few, M. Elise Hyland, Holli C. Ladhani, Brent J. Smolik and J. Kent Wells are independent.  As CEO of the Company, Mr. Tillman is not independent.
DIRECTOR DIVERSITY
The Corporate Governance and Nominating Committee is responsible for reviewing with our Board the appropriate size and composition of the Board. When considering the director nominees, our Board will look at a diverse pool of candidates. We view and define diversity in its broadest sense, which includes gender, ethnicity, age, education, experience and leadership qualities. The Corporate Governance and Nominating Committee reviews each candidate’s business or professional experience, demonstrated leadership ability, integrity and judgment, record of public service, diversity, financial and technological acumen and international experience before recommending a candidate to the Board. Below is a summary of the Board diversity for the directors who are standing for reelection.
Board Gender, Ethnicity, Independence, Tenure and Age Diversity
GENDERETHNICITY
Three of our seven director nominees, including the Lead Director and the current chairs of the Audit and Finance and HESCR Committees, are female.
a2022genv3a.jpg
14% of our
director nominees
self-identify as an ethnicity other than Caucasian/White.
a2022ethv3a.jpg
INDEPENDENCETENUREAGE
 The Board has determined that
each of the nominees, other than
Mr. Tillman, meet the NYSE’s independence standards.
We believe the mix between short-
and long-tenured directors reflects
a balance of company experience
and new perspectives.
The average age
of the director
nominees is 62 years.

BOARD SKILLS AND EXPERIENCE DIVERSITY MATRIX
Our directors have a diversity of experience and skills that span a broad range of industries in the public and not-for-profit sectors. They bring to our Board a wide variety of skills, qualifications and viewpoints that strengthen our Board’s ability to carry out its oversight role on behalf of our stockholders. The table below summarizes key qualifications, skills and attributes each director that is standing for reelection brings to our Board. The lack of a mark for a particular item does not mean the director does not possess that qualification or skill. However, a mark indicates a specific area of focus or expertise that the director brings to our Board. More details on each director’s qualifications, skills and attributes as of April 8, 2022 are included in the director biographies on the subsequent pages.

DIRECTOR COMMITMENTS
It is the expectation of the Board that every member devote the significant time and attention necessary to fulfill his or her duties as a director, including regularly preparing for, attending and actively participating in meetings of the Board and meetings of committees on which they serve. Our Board recognizes that service on other boards of directors often broadens and deepens the knowledge and experience of our directors, while also understanding that service on too many boards can potentially interfere with a director’s ability to perform his or her responsibilities. Under our Corporate Governance Principles, when considering an additional board position, a director should take into account all his or her current commitments, including any existing directorships and board leadership roles, and determine whether the acceptance of a new directorship will compromise his or her ability to perform present responsibilities. Furthermore, before accepting an additional public board position, a director will notify the Chairman of the Board or the Chairman of the Corporate Governance and Nominating Committee, so that the Corporate Governance and Nominating Committee and the Board may evaluate the impacts of such additional commitment as it relates to his or her present duties to the Company. In such event, the Corporate Governance and Nominating Committee and the full Board will consider potential conflicts of interest and the nature of, and time commitment relating to, a director’s service on all boards in evaluating whether the new directorship would interfere with such director’s ability to properly discharge his or her duties to the Company. When reviewing a director’s other board commitments, consideration is given to any public company board leadership positions (e.g., committee chair).
Notwithstanding the foregoing evaluation, under our Corporate Governance Principles, any director who serves on the board of directors of more than three (3) other public companies shall not be nominated for reelection to the Company’s Board at the next annual meeting of stockholders. Any director who is also an executive officer of a public company and serves on the board of directors of more than one (1) other public company shall not be nominated for reelection to the Company’s Board at the next annual meeting of stockholders. Any member of the Company’s Audit and Finance Committee who serves on the audit committee of more than two (2) other public companies shall be removed as a member of the Audit and Finance Committee. Prior to initial appointment to the Company’s Board, and in connection with the annual nomination of candidates for election or reelection to the Board, the Corporate Governance and Nominating Committee reviews and considers each candidate’s outside director time commitments prior to making its recommendation to the full Board for nomination to stand for election or reelection to the Board. All directors standing for reelection are currently in compliance with the Company’s policy on director commitments.

CORPORATE GOVERNANCE
BOARD OF DIRECTORS
Our business and affairs are managed under the direction of our Board, which met 12 times in 2021. Aggregate attendance for Board and committee meetings was over 99% for the full year. No director attended less than 91% of Board or committee meetings in 2021. Under our Corporate Governance Principles, directors are expected to attend the Annual Meeting. Our 2021 Annual Meeting was held virtually and all of our directors nominated at the 2021 Annual Meeting attended the meeting via the Virtual Shareholder Meeting platform.
Our Corporate Governance Principles require our non-employee directors to meet at regularly scheduled executive sessions. An offer of an executive session is extended to non-employee directors at each regularly scheduled Board meeting. In 2021, the directors had four executive sessions and the non-employee directors held seven independent executive sessions.
COMMITTEES OF OUR BOARD
A significant portion of our Board’s oversight responsibilities is carried out through our four standing committees, each of which is comprised solely of independent non-employee directors.
Our four standing committees are the Audit and Finance Committee, the Compensation Committee, the Corporate Governance and Nominating Committee and the Health, Environmental, Safety and Corporate Responsibility Committee.

BOARD OVERVIEW
» Chairman of the Board and Chief Executive Officer: Lee M. Tillman
» Independent Lead Director: Effective May 26, 2021, Marcela E. Donadio succeeded Gregory H. Boyce as the Independent Lead Director
» Active engagement by all directors
» 6 of our 7 director nominees are independent
» All members of our four standing committees are independent
Our Board believes that continuing to combine the position of Chairman and CEO is in the best interest of our Company at this time.
BOARD LEADERSHIP STRUCTURE
We believe that independent Board oversight is essential. Our Board does not have a policy regarding whether the roles of the Chairman and CEO should be separate, but rather makes this determination on the basis of what is best for our Company at a given point in time.

15 MARATHON OIL | CORPORATE GOVERNANCE


Our Corporate Governance Principles require that non-employee directors, all of whom are independent, meet at regularly scheduled executive sessions without the CEO present. The Independent Lead Director presides at these meetings. In addition, our Corporate Governance Principles require that all our principal committees be comprised of entirely independent directors. Effective May 26, 2021, Marcela E. Donadio succeeded Gregory H. Boyce as Independent Lead Director.
INDEPENDENT DIRECTOR LEADERSHIP
As Independent Lead Director, Ms. Donadio is responsible for:
» presiding at executive sessions of independent directors;
» reviewing with Mr. Tillman the proposed Board and committee meeting agendas;
» serving as a liaison between the independent directors and Mr. Tillman in discussing issues from the
     independent executive sessions and ensuring the flow of information;
» reviewing and recommending to Mr. Tillman the retention of consultants who report directly to our Board
    or committees thereof;
» overseeing Board performance; and
» establishing effective communications with stakeholder groups.
BOARD AND COMMITTEE EVALUATIONS
Each year, our Board performs a rigorous full Board evaluation. In addition, each committee also performs an annual evaluation. The evaluation process is managed by the Secretary’s office with oversight from the Corporate Governance and Nominating Committee. For 2021, the evaluation process consisted of:
þEvaluation questionnaires - each director and committee member completed a formal questionnaire. This allows each director and committee member to identify potential improvements.
þIndividual Discussions - our Independent Lead Director met with each director individually to solicit feedback and have an in-depth conversation.
þBoard and committee discussions - the Board and each committee met in Executive Session to discuss the results of the evaluation questionnaires.
þIndependent Lead Director feedback to Board and Chairman - the Independent Lead Director communicated the feedback to the Board from the internal evaluations. The Independent Lead Director also met separately with the Chairman to review feedback.
þImplementation of feedback - as a result of the evaluation process, the Board has implemented changes to the Board and committee meetings, including refining Board and committee agendas and enhancing meeting efficiency.
OUR BOARD’S ROLE IN RISK OVERSIGHT
While our Board and its committees oversee risk management, Company management is responsible for the day-to-day management of risk. We have a robust enterprise risk management process for identifying, assessing and managing risk and monitoring risk mitigation strategies. Our CEO, CFO and a committee of executive officers and senior managers work across the business to manage each enterprise level risk and to identify emerging risks. Our Board annually reviews our enterprise risk management process and the latest assessment of risks and key mitigation strategies. Responsibility for risk oversight by our Board and its committees is delegated as set forth below:

MARATHON OIL | CORPORATE GOVERNANCE 16


»    The Audit and Finance Committee receives regular updates from senior leadership on specific risks identified in the risk management process. These reviews with senior leadership include risks associated with financial and accounting matters and reporting, and operational risks, including cyber-security. The Audit and Finance Committee also monitors compliance with legal and regulatory requirements and internal control systems, and reviews risks associated with financial strategies and the Company’s capital structure. Protecting the privacy of our systems and networks has long been, and will continue to be, a priority. The Audit and Finance Committee is committed to maintaining strong and meaningful privacy and security protections. Our Senior Vice President, Technology & Innovation, and Chief Information Officer regularly provides reports to senior leadership and the Audit and Finance Committee regarding our ongoing assessment of cyber-security threats and risks, data security programs designed to prevent and detect threats, attacks, incursions and breaches, as well as management, mitigation and remediation of potential, and any actual, cyber-security and information technology risks and breaches. In addition, the Audit and Finance Committee and management review reports from internal audit regarding evaluation of our information technology department on a regular basis.
»    The Corporate Governance and Nominating Committee reviews the Board’s and Company’s governance policies and procedures to ensure adherence to best practices and legal requirements. The Corporate Governance and Nominating Committee also reviews director succession planning, director outside commitments and committee assignments to ensure the directors’ skills and backgrounds are utilized to the best interests of the Company.
»    The Compensation Committee reviews the executive compensation program to ensure it does not encourage excessive risk-taking. It also reviews our executive compensation, incentive compensation and succession plans to ensure we have appropriate practices in place to support the retention and development of the talent necessary to achieve our business goals and objectives.
»    The Health, Environmental, Safety and Corporate Responsibility Committee regularly reviews and oversees operational risks, including those relating to health, environment, safety, security and climate change. It reviews risks associated with social, political and environmental trends, issues and concerns, domestic and international, which affect or could affect our business activities, performance and reputation, and monitors climate-related trends, issues, legislation, policies, practices and concerns.
Our Board receives regular updates from the committees about these activities, and reviews additional risks not specifically within the purview of any particular committee and risks of a strategic nature. Key risks associated with the strategic plan are reviewed annually at our Board’s strategy meeting and periodically throughout the year.
RISK ASSESSMENT RELATED TO OUR COMPENSATION STRUCTURE
The Compensation Committee regularly evaluates and considers the role of our executive compensation program in ensuring that our executive officers are incentivized to only take appropriate and prudent risks, and that compensation opportunities do not motivate excessive risk-taking. The practices we employ include:
»    All executive officer compensation decisions are made by either the Compensation Committee, which is comprised solely of independent directors, or by the independent directors for CEO compensation.
»    The Compensation Committee is advised by an independent compensation consultant that performs no other work for executive management or our Company.
»    Our executives do not have employment agreements.
»    The Compensation Committee manages our compensation program to be competitive with those of peer companies and also monitors our program against trends in executive compensation on an annual basis against the broader energy industry and general industry of similar market capitalization. 

17 MARATHON OIL | CORPORATE GOVERNANCE


»    Our compensation program is intended to balance short-term and long-term incentives.
»    Our long-term incentives feature multiple award vehicles and multi-year vesting criteria aligned with long-term ownership, and our executive officers are also subject to ongoing stock ownership requirements.
»    Our annual cash bonus program is based on a balanced set of multiple objective metrics. In addition, the Compensation Committee generally considers the achievement of individual performance goals and overall corporate performance.
»    Annual cash bonuses are paid to executive officers only after the Audit and Finance Committee has reviewed audited financial statements for the performance year.
»    Annual cash bonuses and performance share unit awards are subject to a maximum opportunity.
»    The Compensation Committee regularly evaluates share utilization in our 2019 Incentive Compensation Plan by reviewing overhang levels (dilutive impact of equity compensation on our stockholders) and annual run rates (the aggregate shares awarded as a percentage of total outstanding shares).
»    Our clawback policy applies to annual cash bonuses and is generally triggered with respect to an executive officer in the event of a material accounting restatement due to noncompliance with financial reporting requirements or an act of fraud by that executive officer. Our long-term incentive awards for executive officers have similar provisions.
Our 2021 compensation program for our named executive officers followed the above risk assessment. See the “Compensation Discussion and Analysis” section for additional details.
CORPORATE GOVERNANCE PRINCIPLES
Our Corporate Governance Principles address our Board’s general function, including its responsibilities, Board size, director elections and limits on the number of Board memberships. These principles also address Board independence, committee composition, the process for director selection and director qualifications, our Board’s performance review, the Board’s planning and oversight functions, director compensation and director retirement and resignation. The Corporate Governance Principles are available on our website at www.marathonoil.com under Investors—Corporate Governance.
CODE OF BUSINESS CONDUCT
Our Code of Business Conduct, which applies to our directors, officers, employees and contractors, when acting on our behalf, and which includes our code of ethics applicable to the Company’s principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions, is available on our website at www.marathonoil.com under Investors—Corporate Governance. 
We intend to disclose any amendments and any waivers to our Code of Business Conduct that apply to the Company’s principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions and relate to any element of the Code enumerated in Item 406(b) of Regulation S-K on our website at www.marathonoil.com under Investors—Corporate Governance within four business days. The waiver information will remain on the website for at least 12 months after the initial disclosure of such waiver.
HEALTH, ENVIRONMENTAL, SAFETY AND CORPORATE RESPONSIBILITY
Managing Risk to Operate Responsibly
Our Board’s key oversight role includes reviewing the sustainability of our enterprise and the strength of our risk management efforts. As mentioned above, our four standing committees assist with this oversight. The Health,

MARATHON OIL | CORPORATE GOVERNANCE 18


Environmental, Safety and Corporate Responsibility Committee plays a vital role in reviewing our operational risks, including those relating to health, environment, safety, security and climate change and includes directors with experience in this area.
Minimizing Our Environmental Impact
Environmentally responsible, compliant operations are central to our company values. We actively work to mitigate our operational impacts on the air, water and sensitive habitats and reduce our environmental footprint. We strive to go above and beyond regulatory requirements and invest in environmental performance to achieve this goal.
»    Climate change risk - We recognize the impact of greenhouse gas (GHG) and other air emissions on global climate and air quality. As part of our commitment to sustainability and managing climate-related risks, we’ve established business processes that we continue to evaluate and refine to reduce our emissions and mitigate both current and future energy transition risks to our business. Engaging with external stakeholders to understand their perspectives is a vital component of this effort. In addition, we have made, and intend to continue to make, investments in technologies and processes to drive improvement. Our corporate scorecard sets forth metrics and targets that incentivize achieving our goals and are linked to executive and employee pay, such as a climate-related metric first added in 2020.
»    Reducing air emissions from our operations - We aim to meet global energy demand through responsible, affordable and reliable oil and gas production. Central to this goal is driving significant reductions to both the Scopes 1 and 2 GHG and Scope 1 methane intensity of our operations, consistent with the trajectory of the Paris Climate Agreement. We have a history of taking proactive measures to reduce emissions, including phasing out high-bleed pneumatic controllers, monitoring manual liquids unloading operations and detecting and repairing leaks. We continue to evaluate emissions reduction technologies that address the specific needs and constraints of each of our assets.
In 2021, we introduced a new short-term GHG intensity reduction target of at least 30% for 2021, relative to 2019 baseline, with direct linkage to executive and employee compensation. We also introduced a new medium-term GHG intensity reduction goal of 50% by 2025, relative to 2019 baseline, designed to drive significant reduction in GHG intensity by 2025. During 2021, we realized significant progress against our core environmental objectives, achieving our GHG intensity reduction target of at least 30%. In addition to this meaningful reduction in GHG intensity, the powerful combination of our quantitative GHG intensity reduction initiatives and disciplined capital allocation model that prioritizes free cash flow generation contributed to a significant decline in the Company’s absolute GHG emissions. We also improved our total Company gas capture to 98.8% in 2021 from 97% in 2020. During the third and fourth quarters of 2021, we achieved a total Company gas capture of approximately 99%.
To highlight our commitment to successfully meeting global energy demand with leading environmental performance, in early 2022, we introduced new quantitative goals for the near, medium and long-term horizon across three core areas of focus: GHG intensity, methane intensity and gas capture. These new Company goals, which are set forth in detail in the chart on page 2, complement our existing 2025 GHG intensity objective and are intended to promote external transparency and accountability while also enhancing the internal alignment and employee innovation necessary to deliver such strong performance.
»    Applying water stewardship practices - We practice responsible water sourcing, conservation, reuse, recycling and proper disposal. Our regional water management strategy is designed to reduce the impacts of our water use on stakeholders and the relevant watersheds, and to minimize risks associated with produced water disposal, supply sourcing and business interruption. We target opportunities that

19 MARATHON OIL | CORPORATE GOVERNANCE


conserve fresh water for community needs while reducing business risk linked to access to water resources.
Creating Safe, Healthy and Secure Workplaces
We hold safety as a core value and key component of our ESG performance. We strive to provide safe, healthy and secure workplaces by maintaining top quartile safety performance in comparison to industry peers, as measured by Total Recordable Incident Rate (TRIR) for both employees and contractors. We continuously work to improve our procedures, train our workforce to reduce safety risk, reinforce our strong safety culture and build relationships with our contractor workforce. During 2021, we delivered another strong year of safety performance, as measured by a 0.29 TRIR, our second lowest TRIR since becoming an independent exploration and production company. Our safety performance for both employees and contractors remains a key component of our executive compensation scorecard, underscoring our commitment to keeping our employees and contractors safe. In addition, we believe our workforce is trained and ready to respond if natural disasters, security incidents, operational disruptions or other events occur, and we maintain detailed business continuity plans to protect our workforce and continue critical business functions during sustained efforts, including a public health event such as a pandemic.
Social Investment
We are committed to promoting a diverse and inclusive workplace, respecting human rights and making strategic investments to build healthier, safer, more resilient and stronger local communities.
During 2021, women and people of color accounted for 33% and 30% of our U.S. full-time workforce, an increase from 25% for both five years ago. During 2022, we are committed to publishing our Equal Opportunity and Employment (EEO-1) data, in addition to a new Human Rights Policy.
Key strategic social investments during 2021 included the following:
»    Continued support of Equatorial Guinea’s Bioko Island Malaria Elimination Project, which has contributed to the reduction of all-cause mortality among children under 5 years of age by more than 60% since 2004.
»    Hosted My Home Library book distribution events with Barbara Bush Literacy Foundation at seven elementary schools, including expansion to six schools in the Company’s area of operations outside the city of Houston, helping address the reading gap in underserved communities.
»    Launched the Unconventional Thinking in Teaching Program, awarding grants to 14 teachers to increase teacher retention and amplify the impact of qualified teachers on the future workforce in the Company’s area of operations.
»    Donated 100 laptops and 750 monitors in collaboration with Communities in Schools and Comp-U-Dopt to support remote learning programs.
»    Entered new partnership with the Permian Road Safety Coalition, which has helped contribute to a 35% reduction in Permian Basin roadway fatalities during its first 30 months of existence.
POLICY FOR REPORTING BUSINESS ETHICS CONCERNS
Our Policy for Reporting Business Ethics Concerns establishes procedures for the receipt and treatment of business ethics concerns received by the Company, including those regarding accounting, internal accounting controls or auditing matters. The Policy for Reporting Business Ethics Concerns is available on our website at www.marathonoil.com under Investors—Corporate Governance—Policies and Reporting—Policies.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
Messrs. Deaton and Wells served on the Compensation Committee for all of 2021. Messrs. Few and Smolik joined the Compensation Committee following the 2021 Annual Meeting. There are no matters relating to interlocks or insider participation that we are required to report.
DIRECTOR COMPENSATION
Our Board determines annual retainers and other compensation for non-employee directors. Mr. Tillman, the only director who is also an employee, receives no additional compensation for his service on our Board or as Chairman. Non-employee director compensation is intended to attract qualified directors, ensure that they are fairly compensated for their contributions to our performance and align the interests of directors and stockholders.
CASH COMPENSATION
Our Board is committed to best-in-class corporate governance, including director compensation. Effective January 1, 2021, and complementary to the overall reduction in executive compensation, our Board instituted an approximate 25% reduction to total 2021 non-employee director compensation, excluding chair fees and the 2020 temporary reductions. Additionally, the compensation mix for non-employee directors shifted more to equity. Below are the 2021 non-employee director annual cash retainer and fees.

Directors do not receive meeting fees for attendance at Board or committee meetings. Non-employee directors may defer up to 100% of their annual retainer into an unfunded account under the Company’s Deferred Compensation Plan for Non-Employee Directors (DCP). These deferred amounts may be invested in certain investment options, which generally mirror the investment options offered to employees under the Marathon Oil Company Thrift Plan (Thrift Plan).
EQUITY-BASED COMPENSATION AND STOCK OWNERSHIP REQUIREMENTS
For 2021, each non-employee director received an annual common stock unit award valued at $150,000, which was credited to an account on March 1, 2021, based on the closing stock price on the grant date. These awards were granted under the Company’s 2019 Incentive Compensation Plan (2019 ICP), which is described in further detail under “Long-Term Incentives” in the “Compensation Discussion and Analysis”. Directors may elect to defer settlement of their common stock units until after they cease serving on our Board under the Company’s DCP. Directors who make such a deferral election receive dividend equivalents in the form of additional common stock units, which will be settled in common stock.
Directors who elect not to defer their common stock units receive dividend equivalents in cash, payment of which is deferred until the distribution date of the related common stock units. These awards vest and are payable shortly after the earlier of (a) the first anniversary of the grant date or (b) the director’s departure from our Board.
Director stock ownership requirement of
5x
annual cash retainer
Our stock ownership guidelines require each non-employee director to hold five times the value of his or her annual cash retainer in Marathon Oil stock. Directors have five years from their initial election to our Board to meet this requirement. Directors who do not hold the required level of stock ownership due to fluctuations in the price of our common stock are expected to hold the awards they receive until they have met their requirement. The Corporate Governance and Nominating Committee reviews each non-employee director’s progress toward the requirements during the first quarter of each year to determine whether the market value of the shares, including the value of deferred shares and restricted stock units, satisfies our requirements. As of March 10, 2022, Mses. Donadio and Hyland, and Messrs. Deaton, Few, Smolik and Wells meet the requisite threshold, and Ms. Ladhani is still within the five-year window.
MATCHING GIFTS PROGRAMS
Under our matching gifts programs, we will annually match up to $10,000 in contributions made by non-employee directors to certain tax-exempt educational institutions.

This Compensation Discussion and Analysis focuses on the Company’s 2021 compensation program, how the Company and the Compensation Committee (Committee) responded to market conditions and key features of the new executive compensation program the Company implemented in 2021. Certain of the measures referenced below and identified with a cross (†) are non-GAAP measures, for which reconciliations to comparable GAAP measures and related definitions and discussion are included in Annex A.
2021 EXECUTIVE SUMMARY
In 2021, our industry began to recover from the unprecedented combination of decreased global energy demand due to pandemic conditions and an oversupplied commodity market experienced through most of 2020. These market dynamics caused a significant decrease in stock prices at Marathon Oil and in the broader oil and gas industry during 2020.
Marathon Oil responded quickly and decisively to the sudden and severe conditions that emerged in early 2020, as well as the ongoing macro challenges associated with the COVID-19 pandemic. Our response included reducing capital expenditure programs, lowering our cost structure, improving our balance sheet through gross debt reduction and protecting our free cash flow generation. As the market conditions and commodity prices rebounded during 2021, we stayed disciplined and did not waver from our reinvestment rate capital allocation

27 MARATHON OIL | COMPENSATION DISCUSSION AND ANALYSIS


framework, generating over $2.2 billion of free cash flowin 2021. We dramatically enhanced our balance sheet and investment grade credit rating by accelerating gross debt reduction initiatives. We then successfully transitioned to market leading return of capital to our equity investors through both share repurchases and multiple increases to our base dividend.
The Company produced exceptional results in 2021 guided by our framework for success, as evidenced by our ESG excellence, capital discipline and outsized financial outcomes, with Marathon Oil having the second best performing stock in the S&P 500 Index during 2021.

2021 Program Changes: Realigning Pay to an Evolving Industry
The Committee, with input from its independent compensation consultant and Company’s management, also embarked on a comprehensive re-evaluation and redesign of our executive compensation program for 2021 to align with changes within the industry and to address concerns investors have articulated about traditional industry compensation practices, with the goal of building a program that supports stockholder expectations and rewards strong performance. Some of the key changes and features include:
»    CEO compensation was reduced 25%, and the mix further aligned with broader industry norms; long-term incentive (LTI) awards were reduced 35%. Most of the other NEOs received reductions as well.
»    Growth metrics were eliminated from the compensation scorecards.
»    Our short-term incentive (STI) framework was aligned with key financial and ESG priorities that drive stockholder value.
»    Our LTI framework promotes strong performance versus the broader market and incentivizes free cash flow generation, with all LTI vehicles denominated in shares of our common stock.

MARATHON OIL | COMPENSATION DISCUSSION AND ANALYSIS 28


The Committee’s review of our executive compensation program centered on a fundamental belief that the industry’s traditional compensation model no longer aligned with changes within the industry and new performance accountabilities, both financial and non-financial, specifically excellence in ESG.
The Committee sought to design and implement a program for 2021 that addressed concerns that investors have articulated about industry compensation practices while continuing to align our executives’ interests with those of our stockholders and attract, retain and motivate the best talent. The Committee focused on building a compensation program that would support and reward achievement of the following:
»    Demonstrated excellence in ESG, including peer leading safety and reduced GHG emissions intensity;
»    The generation of sustainable free cash flow and corporate returns at lower and more volatile commodity prices;
»    Differentiated capital efficiency that supports peer-leading enterprise break-even performance;
»    Financial and value creation outcomes, including return of capital to stockholders, that compete with investment opportunities both within the traditional exploration and production (E&P) peer group as well as the broader market; and
»    Total reward compensation opportunities that align more closely with the stockholder experience and that are competitively calibrated primarily against independent E&P peers while also referencing broader energy and general industry data for similar positions.
To that end, for 2021 the Committee approved numerous changes to short-term and long-term incentive metrics, compensation vehicle mix and target officer compensation pay levels, as discussed in more detail under “2021 Executive Compensation Program Elements.”
2021 Operational and Financial Highlights
2021 was a noteworthy year for Marathon Oil, with strong safety and environmental performance, capital discipline and compelling return of capital to stockholders. The Company’s employees delivered outstanding and comprehensive results against our framework for success.
Key 2021 highlights include:
»    We achieved our second best TRIR since becoming an independent E&P company, demonstrating strong safety performance.
»    We achieved a 30% GHG intensity reduction target compared to 2019 and improved total Company gas capture to 98.8%.
»    We generated over $2.2 billion of free cash flowat a 32% reinvestment rate.
»    We increased our base dividend three times.
»    We reduced gross debt by $1.4 billion and annualized cash interest by $50 million.
»    We achieved full year 2021 oil production of 173,000 net bopd and oil-equivalent production of 348,000 net boed.
»    We returned $772 million to equity investors through share repurchases ($724 million of which settled in 2021) and $141 million in base dividends, for a total of $913 million or approximately 30% of cash flow from operations, while still ending the year with over $500 million of cash on hand.
»    We strategically invested to build healthier, stronger and safer local communities.
»    We delivered below plan production expenses and G&A expenses.

2021 CEO Target Compensation Reduced 25%;
LTI Reduced 35%
For 2021, the Committee reduced total target compensation opportunities for most of our NEOs under a new program structure. The Committee reduced the CEO’s total target compensation opportunity by 25% and reallocated the components to align more closely with observed pay practices across a broader array of U.S. industries, while remaining competitive within observed E&P compensation ranges.

PAY FOR PERFORMANCE
Our executive compensation program creates a strong alignment with stockholder interests. We deliver the largest portion of NEO compensation through equity-based, long-term incentives that tie compensation to the absolute and relative performance of our stock. Our annual bonus delivers payments directly aligned with performance against our strategic, financial and operational commitments each year.
The compensation that Mr. Tillman, our CEO, will realize from his outstanding awards and opportunities has aligned well with stock price and Company performance. His reported pay, as detailed in the Summary Compensation table, does not reflect the actual value he realizes from at-risk incentive opportunities.
Mr. Tillman’s realizable compensation from the total opportunities awarded from 2019 through 2021 aligns well with stock price performance on an annual and a cumulative three-year basis. The bar charts below compare Mr. Tillman’s realizable compensation as a percent of target opportunity to our annual total shareholder return (TSR) performance and his cumulative realizable pay to cumulative TSR performance over the period.
Realizable compensation for each year includes each year’s base salary paid, actual annual bonus earned and the year-end value of each year’s long-term incentive award. The cumulative realizable pay numbers include the value of all equity granted over the period as of December 31, 2021. Target compensation represents annual salary rate, target bonus opportunity and target grant value of LTI awards.

COMPENSATION PHILOSOPHY
COMPENSATION PHILOSOPHY
Our success is based on financial performance and operational results, and we believe that our executive compensation program is an important driver of that success. The primary objectives of our program are as follows:
Pay for performanceOur program is designed to reward executives for their performance and motivate them to continue to perform at a high level. Cash bonuses based on annual performance, combined with equity awards that vest over several years, balance short-term and long-term business objectives.
Encourage creation
of long-term
stockholder value
Equity awards and stock ownership requirements align our executives’ interests with those of our stockholders. Our NEOs’ LTI awards feature equity-based grants with large portions tied to financial performance and long-term stockholder returns.
Pay competitivelyWe provide market-competitive pay levels to attract and retain the best talent, and we regularly benchmark each component of our pay program, including our benefit programs, to ensure we remain competitive.

31 MARATHON OIL | COMPENSATION DISCUSSION AND ANALYSIS


COMPENSATION GOVERNANCE AND BEST PRACTICES
The Committee periodically evaluates market best practices and pay programs at other companies, and modifies our compensation program as necessary. The Committee seeks to provide balanced incentives, while managing compensation risks appropriately in the context of our business objectives. Our program incorporates the following best practices:
WHAT WE DOWHAT WE DON’T DO
þEmphasize at-risk compensation designed to link pay to performance; all LTI vehicles denominated in sharesýOffer employment agreements to our executive officers
þInclude ESG metrics in annual incentive compensation design to further align with stakeholder interestýProvide gross-up payments to cover excess parachute payment excise taxes for executive officers
þMaintain stock ownership requirements for executive officers and directorsýAllow margin, derivative or speculative transactions with our company stock, such as hedges, pledges and margin accounts, by executive officers and directors
þMaintain “double-trigger” change in control cash severance payments and accelerated vesting of certain equity awardsýReward executives for excessive, inappropriate or unnecessary risk-taking
þIncorporate compensation clawback provisions in annual and long-term incentives
þOffer minimal use of perquisites and no related tax gross-ups
þProactively engage with our stockholders on compensation, environmental and governance issues
þEngage an independent compensation consultant to advise the Committee
þDedicate significant time each year to robust executive succession planning and leadership development
2021 Say on Pay and Stockholder Engagement
The Committee considers the outcomes of the Company’s advisory stockholder vote on our executive compensation program and any associated outreach initiatives when making compensation decisions.
At our 2021 Annual Meeting, our stockholders expressed support for the Company’s proposals and all of our agenda items were approved. Within those approvals, approximately 92% of shares voted were in favor of our 2021 “say-on-pay” agenda item. Overall, investor feedback has been very positive regarding changes made to our executive compensation program and its link between our pay and performance.

92%
The Company is committed to regular communication and engagement with its stockholders and other stakeholders. During 2021, we engaged with and solicited valuable feedback from a broad base of investors on various topics, such as compensation, environmental and social issues and governance practices. Feedback from these meetings is shared with directors through senior management reports to the Board and its committees throughout the year. We remain committed to engaging stockholders regularly and to ensuring alignment of our compensation program and stockholder and other stakeholders’ interests.

MARATHON OIL | COMPENSATION DISCUSSION AND ANALYSIS 32


HOW WE DETERMINE EXECUTIVE COMPENSATION
Compensation Committee
The Committee is responsible for establishing and overseeing our executive compensation program and policies that are consistent with our overall compensation philosophy. In making such decisions, the Committee considers a variety of factors, including stockholder feedback, information provided by its independent compensation consultant, our CEO’s input, peer group and broader industry data, each executive’s experience in the role, Company and individual performance, internal pay equity and any other information the Committee deems relevant in its discretion.
Compensation Consultant
For 2021, the Committee directly engaged Meridian Compensation Partners LLC (Meridian) as its independent compensation consultant to advise the Committee on executive compensation matters. Meridian provides the Committee with information on items such as emerging industry trends (in both broader oil and gas and general industries), legislative issues, defining the Company’s peer group and benchmarking our executive compensation program against the compensation peer group. Meridian provides no other services to the Company or our executive officers, and the Committee has the right to terminate the services of Meridian and appoint a new compensation consultant at any time.
Meridian interacts with several of our officers and employees as necessary. In addition, Meridian may seek input and feedback from members of our management regarding its work product prior to presentation to the Committee to confirm that information is accurate or address other issues. We believe that Meridian provides an independent perspective to the Committee.
The CEO’s Role
The Committee seeks significant input from the CEO on compensation decisions and performance appraisals for all executive officers other than himself. All final compensation decisions for our executive officers are made by the Committee, except that the independent members of our full Board determine and approve the CEO’s compensation level. The CEO does not provide recommendations or participate in Committee or Board discussions concerning his own compensation.
Peer Groups
Peer group benchmarking is one of several factors the Committee considers in setting pay and is reviewed at least annually by the Committee. Following a comprehensive review of the peer group as part of the broader compensation framework assessment, the Committee determined to utilize two peer groups in 2021. One peer group is used to benchmark targeted compensation levels for our executives (compensation peer group), and a second peer group is used to measure relative Company performance in our LTI program (performance peer group). The performance peer group (excluding the S&P 500 Energy Index and the S&P 500 Index) is also used to determine stretch performance for certain metrics in our annual cash bonus program by measuring Company performance versus peer performance (to the extent public data is available).
Our compensation peer group is comprised of independent E&P companies of similar market capitalization and enterprise value that the Committee believes provide the best external benchmarks for the market in which we compete for executive talent. Pertinent financial measures considered in determining the compensation peer group are enterprise value, market capitalization, assets and revenue. Our performance peer group includes broader market comparisons with a focus on independent E&P companies with which we compete for investor capital.

The Committee adjusted last year’s (2020) compensation peer group by removing Chesapeake Energy Corporation, EOG Resources Inc., Hess Corporation and Pioneer Natural Resources and adding Cabot Oil and Gas Corporation, Diamondback Energy Inc., EQT Corporation and PDC Energy Inc. to create its 2021 compensation peer group.
See “Long-Term Incentives” for the 2021 performance peer group for LTI awards.
Both compensation and performance peer groups are assessed and updated as appropriate on an annual basis and in consultation with the Committee’s independent compensation consultant.
Compensation Benchmarking Process
The Committee conducts an annual comparison of the compensation of our NEOs to the compensation of executives with similar job responsibilities among companies in our compensation peer group, based upon information gathered and provided by Meridian through surveys and public company disclosure. The Committee references this competitive market analysis in making compensation decisions for the coming year. The Committee has typically aligned executive total direct compensation opportunities within a competitive market range of similar opportunities across the compensation peer group, adjusted for internal parity and individual factors across executives. We define total direct compensation as the sum of base salary, target annual cash bonus and the target grant value of LTI awards.
In October 2020, Meridian provided the Committee a market analysis that included information regarding compensation peer group executives’ base salaries, target annual bonus levels and the mix and level of long-term incentives. According to this analysis, Marathon Oil’s NEO compensation levels varied by individual, but overall were positioned at the lower end of the 25th to 75th percentile range reflecting the reductions in total direct compensation that were implemented by the Committee.
2021 EXECUTIVE COMPENSATION PROGRAM ELEMENTS
Our executive compensation program includes base salary, annual cash bonuses, LTI awards and other benefits and perquisites. By design, a significant portion of our executive officers’ overall compensation, including annual cash bonuses and LTI awards, is “performance-based,” and the opportunity to earn those awards is largely dependent on Company and individual performance. The Committee determines a total compensation opportunity for each executive officer based on a review of compensation benchmarks from independent upstream companies, broader oil and gas companies and general industry, a review of our compensation philosophy and the Committee’s subjective judgment. Because the Committee does not set fixed percentages for each element of compensation, the mix may change over time as the competitive market moves, governance standards evolve or our business needs change.

Eighty-seven percent of our CEO’s 2021 total target direct compensation is influenced by Company performance. The allocation of our compensation components, with a significant emphasis on LTI awards, aligns with the practices of our compensation peer group with reference to the broader industry. The following pie charts reflect the 2021 pay mix of total target direct compensation components for our CEO and other NEOs, respectively.

2021 TOTAL TARGET DIRECT COMPENSATION OVERVIEW
Following the comprehensive re-evaluation of our executive compensation program in the second half of 2020, the Committee determined 2021 base salaries, target annual cash bonus opportunities and LTI awards in February 2021. The Committee determined the payment of 2021 annual cash bonuses in January 2022, after 2021 business results were known and internally audited.
The following table summarizes the elements of total direct compensation the Committee awarded to our NEOs for 2021 as part of our regular compensation program. The amounts shown include the target opportunity for short-term incentives and target grant value for long-term compensation. These numbers differ from those shown in the Summary Compensation Table and the Grants of Plan-Based Awards Table. Target LTI values reflect established compensation valuation methodologies that are similar to, but differ from, the methodologies used for accounting purposes as reflected in the Summary Compensation Table and the Grants of Plan-Based Awards Table. Target bonus opportunity does not reflect actual performance results.

(1) 2021 Base Salary reflects salaries approved by the Committee in February 2021.
BASE SALARY
The primary purpose of base salary is to recognize and reward overall responsibilities, experience and established skills. In setting base salary, the Committee compares each NEO’s current salary to the competitive market ranges of E&P peers and broader general industry companies and considers each individual’s experience and expertise, the value and responsibility associated with the role and internal pay equity. The Committee does not use a formula to calculate base salary increases for NEOs.
In February 2021, the Committee reviewed base salaries and the considerations noted above. The Committee determined to make no base salary increases for the NEOs at that time, except for Mr. Henderson who received a base pay increase effective March 1, 2021, in recognition of his promotion to EVP, Operations following the retirement of Mr. T. Mitchell (“Mitch”) Little at the end of 2020.

ANNUAL CASH BONUS
The Company maintains an annual cash bonus program that rewards executives for the Company’s achievement of short-term financial and operational goals that drive stockholder value, as well as for their individual performance during the year. At the beginning of the year, the Committee determines a fixed target bonus opportunity for each executive, based on an observed range of market practices, as well as each executive’s experience, relative scope of responsibility, internal pay equity considerations and any other information the Committee deems relevant in its discretion. The executive can earn from 0% to 200% of the target bonus opportunity based on the Company’s performance against a scorecard of quantitative business metrics and qualitative objectives, as well as the individual’s performance. The Company also uses this same scorecard to determine bonus funding for other employees across the Company. The scorecard conveys to employees the Company’s top priorities and collective business objectives for the entire organization.
The Committee determined the 2021 annual cash bonus payout for each NEO based on its assessment of the following:
»    Quantitative Company performance metrics, weighted at 80%;
»    Qualitative Company performance objectives, weighted at 20%; and
»    Individual performance, including achievement of pre-established goals, leadership and ethics, and overall value that the officer created for the Company.

For 2021, the Company simplified the annual cash bonus design to focus on Marathon Oil’s core financial and ESG framework, in conjunction with the Committee’s assessment of other year-end results and individual performance. These changes were intended to bring an immediate focus on items that should positively impact long-term sustainability and stockholder value.
2021 Quantitative Performance Metrics
During the first quarter of 2021, the Committee established quantitative performance metrics for the bonus program, with several key differences from prior annual bonus programs. The 2021 quantitative performance metrics, which collectively represent 80% of the total bonus award opportunity, continued a focus on safety, elevated the importance of measurable ESG metrics and increased focus on financial leadership through differentiated capital efficiency, maintaining capital discipline and sustainable growth in cash flow per debt adjusted share. Production goals were eliminated from the scorecard for 2021.

The Committee determined the target level of performance for each metric by evaluating factors such as performance achieved in the immediately preceding year, anticipated challenges for 2021, top tier peer performance and Company strategy. The Company set aggressive, competitive target and stretch goals to challenge our employees and drive stockholder value throughout the year. In the case of GHG emissions, a stretch goal was set at the top quartile of our peers, and in the case of enterprise breakeven, a stretch goal was set to be the lowest of our peers.
In early 2022, the Committee evaluated the Company’s 2021 performance against the quantitative metrics established early in 2021. The Company delivered exceptional operational and financial results during 2021, which led to strong performance against the quantitative metrics. Safety results, as measured by TRIR, exceeded target, with the second best TRIR since becoming an independent E&P company. GHG Emissions Intensity results also exceeded target, with a 30% reduction in GHG emissions intensity measured against the 2019 baseline. Further, the Company achieved very strong financial results in 2021, supported by execution excellence, capital discipline and higher commodity prices. This translated into the delivery of results exceeding target in the category of Enterprise Breakeven, and exceeding the stretch goals in the categories of Reinvestment Rate and Cash Flow Per Debt Adjusted Share.
The following table shows the targets and weightings established for 2021 by the Committee and the performance achievement approved by the Committee in early 2022 (Performance Achieved) for each quantitative performance metric.

(1) Calculated by dividing (a) the Occupational Safety and Health Administration (OSHA) recordable incidents multiplied by 200,000 by (b) the total number of exposure hours. This metric includes both Company employees and contractors and is applied to Company operated properties only.
(2) Total GHG emissions intensity excluding acquisitions and dispositions. GHG emissions intensity is defined as tonnes of CO2e on a weighted basis divided by production (mboe). GHG emissions intensity performance achieved for 2021, as approved by the Committee in early 2022, reflects actuals through Q3 2021 and estimates for the remainder of the year.
(3) Enterprise breakeven is the minimum WTI pricing needed to have free cash flow before dividend equal to zero. Other product pricing are held at strip pricing.
(4) Reinvestment rate is a non-GAAP measure for which a reconciliation to the comparable GAAP measure is included in Annex A. Reinvestment rate is calculated by dividing capital spend (defined as development capital plus resources capture spend) by operating cash flow before working capital.
(5) Cash flow per debt adjusted share is calculated by dividing cash flow (defined as operating cash flow before working capital plus net interest after tax) by total shares including debt shares (debt shares are the average net debt during a calendar year divided by the stock price, or simply equitizing debt). Cash flow per debt adjusted share is a non-GAAP measure for which there is no GAAP equivalent.
(6) Target is based off the 2021 business plan at January 15th 30-day monthly average strip pricing (December 16th through January 15th) - 2021 WTI:$49.31, Mt. Belvieu $18.65, HH $2.72. Cash flow per share target utilizes the same January 15th 30-day average stock price (December 16th – January 15th) of $7.22 to calculate debt shares.
2021 Qualitative Objectives
After assessing the Company’s quantitative performance metrics, the Committee evaluated qualitative objectives, representing 20% of the total bonus award opportunity. The Committee evaluated objectives and achievements not considered by the quantitative metrics, such as ESG commitments and other prevailing business priorities. The Committee considered, among other things, the following Company achievements during 2021:
»    Improved quarterly gas capture trends, exceeding 99% enterprise gas capture in 2H 2021, in furtherance of its ESG commitments;
»    Reduced gross debt by $1.4 billion and annualized cash interest by $50 million;
»    Increased base dividend by 100% in 2021 while keeping enterprise breakeven (including dividend) at $35 WTI;
»    Returned $772 million to investors through repurchases ($724 million of which settled in 2021) (48.5 million shares of Marathon Oil common stock at $15.92 per share equating to approximately 6% of shares of Marathon Oil common stock outstanding);
»    Returned over $2.3 billion (or over 70% of cash flow from operations) to investors, consisting of:
    $1.4 billion in gross debt reductions,
    $772 million in share repurchases ($724 million of which settled in 2021), and
    $141 million in base dividends,
while still ending the year with over $500 million of cash on hand;
»    Achieved full year 2021 oil production of 173,000 net bopd and oil-equivalent production of 348,000 net boed;    
»    Delivered on $1 billion capital program commitment and achieved full year oil and boe volume targets despite external impacts;
»    Achieved year-end 2021 proved reserves totaling 1,106 million barrels of oil equivalent (mmboe), an increase of 134 mmboe, or 14%, in comparison to year-end 2020 proved reserves;    
»    Delivered below plan production expenses and G&A expenses;
»    Delivered success at resource replacement; and
»    Engaged in impactful community relations projects, demonstrating the Company’s commitment to the communities in which it does business.

MARATHON OIL | COMPENSATION DISCUSSION AND ANALYSIS 38


The successful achievement of these qualitative objectives, among others, produced an exceptional year that delivered outsized financial outcomes and drove differentiated execution, with the Company having the second best performing stock in the S&P 500 Index during 2021.
Upon review of these qualitative achievements, the Committee concluded that the Company had achieved overall performance above target expectations, resulting in a 31% weighted payout score for the qualitative bonus opportunity.

2021 Individual Performance
The Committee maintains discretion to adjust individual cash bonuses to recognize critical performance factors and accomplishments that may not have been fully considered in the performance score calculation. The Committee considered each NEO’s contribution to the exceptional corporate performance during 2021, which delivered the best annual Company equity performance since becoming an independent E&P. In evaluating our NEOs’ contributions during 2021, the Committee considered each NEO’s specific contribution to this outstanding performance and our Company’s other key achievements. Individual performance adjustments of 120% were applied for each of our NEOs based on their contributions, which, collectively, resulted in:
»    Exceptional delivery on our priorities for capital allocation;
»    Differentiated return of capital to investors via a powerful combination of accelerated gross debt reduction, multiple consecutive raises to our base dividend and fourth quarter share repurchases that led the performance peer group with approximately 70% of cash flow from operations returned to investors; and
»    Outperformance relative to peers and the broader S&P 500 across key metrics, including equity performance that ranked number two in the S&P 500.

LONG-TERM INCENTIVES
Long-term incentive, or LTI, awards align the interests of NEOs and stockholders over the long term and are intended to represent the largest portion of the NEO’s total direct compensation. LTI is designed to incentivize executives to achieve strategic goals that will maximize long-term stockholder value and also encourage retention through continued service requirements. These awards assist NEOs in establishing and maintaining significant equity ownership and place a meaningful portion of compensation at risk based on our common stock price performance. LTI awards are currently granted under the Marathon Oil Corporation 2019 Incentive Compensation Plan, or 2019 ICP, which is the Company’s omnibus, stockholder approved incentive compensation plan.
As part of the comprehensive review of our executive compensation program in 2020, the following changes were made to our 2021 LTI awards to better align with industry imperatives:
Overview of 2021 LTI Program Changes
Key ChangeObjective
Three LTI Vehicles (Restricted stock units, TSR based performance units, and FCF based performance units), all denominated in sharesFurther diversifies LTI Metrics; tied to share performance & ownership
S&P 500 and S&P Energy added to peer group for TSR based performance unitsMitigates overreliance on TSR vs. E&P peers; promotes strong performance vs. broader market
Introduction of FCF based performance units and elimination of stock options from LTI award mixUnderscores commitment to sustainable FCF
The 2021 LTI program consists of three vehicles, all denominated in shares of our common stock:
» Free cash flow based performance unit awards (FCF PSUs), which comprise 25% of the award mix;
» TSR based performance unit awards (TSR PSUs), which comprise 25% of the award mix; and
» Restricted Stock Units (RSUs), which comprise 50% of the award mix.
The Committee believes this allocation spreads performance risk and eliminates overreliance on a single performance metric.
The Committee awards LTI based on a target award value that reflects competitive market data, each NEO’s performance and each NEO’s target total compensation.
Each year, the Committee approves target award values at its regularly scheduled February meeting. Beginning in 2021, the grant date is aligned with the grant date for awards to other employees, which is typically March 1 of each year. The actual LTI compensation realized by each NEO depends on the price of the underlying shares of common stock at the time of vesting and, in the case of performance units, our performance relative to the respective performance metric (TSR relative to that of our performance peer group for the TSR PSUs and our generation of free cash flow for the FCF PSUs).
2021 Long-Term Incentive Awards
Based on the factors described above, the Committee awarded LTI with a grant date of March 1, 2021, to each NEO. The table below lists the target grant LTI value, reflecting the aggregate of FCF PSUs, TSR PSUs and RSUs, for each NEO. Target LTI values reflect established compensation valuation methodologies that are similar to, but differ from, the methodologies used for accounting purposes as reflected in the Summary Compensation Table and the Grants of Plan-Based Awards Table. Additional information about each LTI award, including the number of shares subject to each award, is shown in the Grants of Plan-Based Awards Table.

Mr. Henderson$1,200,000
Ms. Warnica$1,000,000
FCF Performance Units
The FCF performance unit awards are designed to focus NEOs on generating free cash flow across a wide range of commodity prices, which enables the Company to support our objective of returning cash back to stockholders. For purposes of these awards, free cash flow is calculated before dividends and is determined as follows: net cash provided by operating activities adjusted for working capital, less capital expenditures and includes EG LNG return of capital and other. It will be modified to exclude the impact, whether positive or negative, of any major acquisition or disposition, as determined by the Committee. The Committee generally has sole and absolute discretion to reduce the final payment associated with any performance unit award as it may deem appropriate. FCF performance units are denominated in shares and earned as set forth below and, if earned, will be paid in cash.
In March 2021, the Committee awarded the NEOs FCF performance units that will vest based on cumulative free cash flow for the two-year performance period ending December 31, 2022. The percentage of units that can be earned ranges from 0% to 200% of the units granted based on the payout table below, and subject to certain continued employment requirements.

During the performance period, if cumulative free cash flow of $728.5 million is achieved, based on a quarterly assessment, 50% of target units will have their value determined based on the average of the daily closing price of a share of our common stock during the final thirty calendar days ending on the last trading day of the quarter in which cumulative free cash flow of $728.5 million is achieved. If cumulative free cash flow of $1,457 million is achieved during the performance period, based on a quarterly assessment, an additional 50% of target units (or 100% of target units if cumulative free cash flow of $728.5 million is achieved during the same quarter) will have their value determined based on the average of the daily closing price of a share of our common stock during the final thirty calendar days ending on the last trading day of the quarter in which cumulative free cash flow of $1,457 million is achieved.
At the end of the performance period, if cumulative free cash flow achieved during the performance period is less than $728.5 million, any earned units (i.e., less than 50% of target) will have their value determined based on the average of the daily closing price of a share of our common stock during the final thirty calendar days ending on the last trading day of the performance period. If, at the end of the performance period, cumulative

41 MARATHON OIL | COMPENSATION DISCUSSION AND ANALYSIS


free cash flow achieved is greater than $1,457 million, any incremental units earned greater than target will have their value determined based on the average of the daily closing price of a share of our common stock during the final thirty calendar days ending on the last trading day of the performance period.
After completion of the performance period, earned awards are paid in cash with the final cash value determined by the number of units granted multiplied by the vesting percentage, with vested units valued based on the valuation determination described above. Dividend equivalents accrue and are paid in cash based on the number of shares earned at the end of the performance period.
TSR Performance Units
The Committee believes that a performance unit award based on TSR relative to the broader market and industry peer companies aligns pay and Company performance. The performance peer group shown below includes the S&P 500 Index, the S&P Energy Index and select industry peers. TSR is determined by adding the sum of stock price appreciation or reduction per share, plus cumulative dividends per share for the performance period, and dividing that total by the beginning stock price per share. Beginning in 2021 for purposes of this calculation, the beginning and ending stock prices are the averages of the closing stock prices for the ninety calendar days immediately preceding the beginning and ending dates of the performance period. The Committee generally has sole and absolute discretion to reduce the final payment associated with any performance unit award as it may deem appropriate. TSR performance units, if earned, will be paid in shares of our common stock.
2021 TSR Performance Units
In March 2021, the Committee awarded the NEOs performance units that will vest based on TSR for the three-year performance period ending December 31, 2023, relative to the 2021 performance peer group.

If there is an announcement during the performance period of an event that if completed would result in a peer group member either ceasing to exist or no longer being a company for which TSR can be calculated from publicly available information, then upon such announcement, that peer group member is removed from the performance peer group for LTI. The payout percentages for the top two and bottom three peers maintain the vesting percentages of 200% and 0%, respectively, and the remaining peer group percentages will be determined using linear interpolation between 35% and 200% for the smaller performance peer group. Due to the merger between Cimarex and Cabot, the performance peer group for LTI was reduced from 13 to 12 companies in October 2021.
2020 TSR Performance Units
The TSR performance units granted in February 2020 have a performance period end date of December 31, 2022, and as of December 31, 2021, followed the payout table below. These awards, if earned, are paid in shares of our common stock, except for accrued dividend equivalents, which are paid in cash. Since the time of grant, due to merger and acquisition activity, Noble Energy, Inc. (Noble Energy) and Cimarex are no longer existing companies and, therefore, have been removed from the peer group for the applicable performance period in accordance with the award agreement terms. The payout percentages for each ranking were recalibrated over the 10 companies, as shown in the following payout table.

2019 TSR Performance Units
For the performance period ending December 31, 2021, we ranked 6 out of 10 companies. Per the award agreement terms as approved by the Committee at the time of grant, due to their acquisitions, Anadarko Petroleum Corporation and Noble Energy, both part of the peer group in 2019, were replaced with Cimarex and Concho Resources Inc. (Concho), respectively. Also since the time of grant, due to merger and acquisition activity, Concho and Cimarex are no longer existing companies, and under the award terms, no replacement peer companies remained. Therefore, following the respective mergers of Concho and Cimarex in 2021, the Committee approved recalibrating the payout percentages over the smaller 10 company peer group. In January 2022, the Committee certified the final number of vested shares of common stock for each NEO for the performance period ending December 31, 2021. The vested shares of common stock were 243,835; 63,609; 53,007; and 21,202 for each of Messrs. Tillman, Whitehead, Wagner and Henderson, respectively.

Restricted Stock Units
The Committee awards RSUs for diversification of the LTI award mix, for consistent alignment between executives and stockholders and for retention purposes. RSUs provide recipients with the opportunity for capital accumulation, leading to retention and stock ownership and a more predictable long-term incentive value than is provided by performance units or stock options.
RSUs awarded in 2021 generally vest in one-third increments over a three year vesting period. RSUs, if earned, will be paid in shares of our common stock. Prior to vesting, recipients receive dividend equivalents on the RSUs and do not have voting rights during the vesting period. Restricted stock and RSUs granted prior to 2021 generally vest upon completion of a three year vesting period.

OTHER BENEFITS
Perquisites
We offer limited perquisites to our NEOs. We believe these perquisites are reasonable, particularly because the cost of these benefits constitutes a small percentage of each NEO’s total compensation. The Committee assesses these perquisites at least annually as part of its total competitive review of executive compensation. We do not provide any tax gross-ups on these perquisites. The perquisites available to our NEOs include reimbursement for certain tax, estate and financial planning services up to $15,000 per year, an enhanced annual physical examination and a Company-provided car service for our CEO. Limited personal use of Company aircraft was available to our NEOs prior to the sale of Company aircraft in 2021, and following that, limited personal use of chartered aircraft is available to our NEOs. Family members and guests may also accompany officers on business travel. Any aggregate incremental cost to the Company resulting from the personal use of the Company or chartered aircraft would be included in the “All Other Compensation” column of the Summary Compensation Table. Our NEOs also participate in the health, retirement, matching gift program and other benefit plans generally available to our U.S. employees.
See the “All Other Compensation” column of the Summary Compensation Table and the footnotes following the Summary Compensation Table for additional details concerning the perquisites provided to our NEOs in 2021.
Retirement Benefits
We offer our NEOs the opportunity to provide for retirement through four plans.
»    Marathon Oil Company Thrift Plan (Thrift Plan) – A tax-qualified 401(k) plan.
»    Retirement Plan of Marathon Oil Company (Retirement Plan) – A tax-qualified defined benefit pension plan.
»    Excess Benefit Plan (Excess Plan) – A nonqualified plan allowing employees to accrue benefits above the tax limits, with components attributable to both the Thrift Plan and the Retirement Plan.
»    Marathon Oil Company Deferred Compensation Plan (Deferred Compensation Plan) – A nonqualified plan that grows when an NEO accrues benefits above the tax limits in the Thrift Plan or when an NEO defers a portion of his or her eligible compensation.
The Thrift Plan and the Retirement Plan are broad-based plans that are open to all eligible employees of the Company. Benefits payable under our qualified and nonqualified plans are described in more detail in “Post-Employment Benefits” and “Nonqualified Deferred Compensation.”
We also currently sponsor retiree health programs for a broad-based group of employees, including the NEOs hired before 2017, who also meet certain eligibility requirements. As of March 10, 2022, Mr. Henderson is the only NEO who has met these eligibility requirements.
Change in Control and Severance Benefits
Our NEOs do not have employment agreements but are eligible for change in control termination benefits under the Marathon Oil Corporation Officer Change In Control Severance Plan (Change in Control Plan), as described under “Potential Payments upon Termination or Change in Control.” We believe these change in control benefits are necessary to attract and retain talent within our industry, ensure continuity of management in the event of a change in control and provide our NEOs with the security to make decisions that are in the best interests of stockholders.
Our Board may exercise discretion to make severance payments to executives on a case-by-case basis. We have a policy requiring that our Board seek stockholder approval or ratification of certain severance agreements (not including the Change in Control Plan) for senior executive officers that would require payment of certain cash severance benefits exceeding 2.99 times the officer’s base salary plus the most recent annual cash bonus paid.

STOCK OWNERSHIP REQUIREMENTS
All of our officers who are “executive officers” for purposes of Section 16 of the Exchange Act are subject to our stock ownership requirements, which are intended to reinforce the alignment of interests between our officers and stockholders.

Executive officers have five years from their respective appointment or promotion dates to achieve the designated stock ownership level. The Committee reviews each executive officer’s progress toward the requirements during the first quarter of each year to determine whether the market value of shares, including the value of unvested shares and RSUs, satisfies our requirements. Stock options and performance units are not counted as shares owned in measuring stock ownership. Executive officers who do not hold the required level of stock ownership must hold the shares they receive upon vesting of restricted stock, RSUs or exercise of stock options (after payment of exercise prices and after taxes) until they have met their requirement. As of March 10, 2022, each currently employed NEO meets the requisite threshold other than Ms. Warnica, who is still within the five-year window. To ensure that they bear the full risks of stock ownership, our officers, including our executive officers, are prohibited from engaging in hedging transactions related to our stock.
TAX CONSIDERATIONS
The Committee considers the tax effects to both the Company and the NEOs when making executive compensation decisions. While the Committee endeavors to deliver compensation in a tax efficient manner, the Committee’s priority is to provide performance-based and competitive compensation. Therefore, some compensation paid to NEOs is not deductible due to the limitations imposed by Section 162(m) of the Internal Revenue Code, which limits the deduction that we can take to $1 million per “covered employee” each year.

(1)    These columns reflect the aggregate grant date fair values calculated in accordance with generally accepted accounting principles in the United States regarding stock compensation. Assumptions used in the calculation of these amounts are included in footnote 19 to our consolidated financial statements in our annual reports on Form 10-K for the years ended December 31, 2021, December 31, 2020 and December 31, 2019. For 2021, 2020 and 2019, the Stock Awards column also includes the grant date fair value of the share-denominated performance units granted in March 2021, February 2020, February 2019, respectively. TSR performance unit grants made in March 2021, February 2020 and February 2019 will be share settled and FCF performance unit grants made in March 2021 will be settled in cash. The value ultimately realized by the officers upon the actual vesting of the awards may or may not be equal to this determined value, as these awards are subject to market conditions and have been valued based on an assessment of the market conditions as of the grant date. The maximum (200%) payouts for the 2021 performance units using the December 31, 2021 closing stock price of $16.42 would be: for Mr. Tillman, $8,796,391; for Mr. Whitehead, $2,748,839; for Mr. Wagner, $2,199,098; for Mr. Henderson, $1,759,239 and for Ms. Warnica, $1,466,043. See the “Grants of Plan-Based Awards Table” and “Long-Term Incentive Awards” for further detail on our performance unit program.
(2)    This column reflects annual cash bonus payments, determined by the Committee and paid in the first quarter of the following year respectively, pursuant to the Company’s annual cash bonus program. These awards are discussed in further detail in our Compensation Discussion and Analysis under “Annual Cash Bonus.”
(3)    This column reflects the annual change in accumulated benefits under our retirement plans. See “Post-Employment Benefits” for more information about our defined benefit plans and the assumptions used in calculating these amounts. No deferred compensation earnings are reported in this column because our non-qualified deferred compensation plans do not provide above-market or preferential earnings.
(4)    The following table describes each component of the “All Other Compensation” column for 2021 in the Summary Compensation Table. For additional information regarding perquisites, see “Perquisites” in our Compensation Discussion and Analysis.

(a)    All regular employees in the United States, including our NEOs, are eligible to receive annual physical and wellness incentives. However, officers may receive an enhanced physical under the executive physical program. This column reflects the average incremental cost of the executive physical program. Due to Health Insurance Portability and Accountability Act confidentiality requirements, we do not disclose actual use of this program by individual officers.
(b)    This column reflects reimbursement for professional advice related to tax, estate and financial planning. The maximum annual benefit is $15,000, and reimbursements are attributed to the calendar year in which services are performed. Due to processing delays, the actual amount reimbursed to an officer may exceed $15,000 in a given year.
(c)    For Mr. Tillman, this column reflects access to a Company-provided car service based on cost to the Company. This benefit is offered to Mr. Tillman to allow the efficient use of his time and to provide safe transportation given the demands of his role, including travel, after hours/weekend obligations and extended work hours. We provide access to this benefit because we believe that the cost is outweighed by the convenience, increased safety and efficiency that it offers. This column would also reflect the aggregate incremental cost to the Company resulting from any permitted limited use of Company aircraft by NEOs. However, no NEOs used the aircraft for this purpose in 2021. In limited circumstances, family members were allowed to accompany officers on Company aircraft for business travel. However, this did not result in an aggregate incremental cost to the Company in 2021.
(d)    This column reflects amounts contributed by us under the Thrift Plan and related non-qualified deferred compensation plans. See “Post-Employment Benefits” and “Nonqualified Deferred Compensation” for more information about the non-qualified plans.
(e)    The amounts shown represent contributions made on behalf of the NEOs for 2021 contributions under our matching gifts programs for universities and approved not-for-profit charities.

POST-EMPLOYMENT BENEFITS
Marathon Oil offers NEOs the opportunity to save for retirement as follows:
»    Marathon Oil Company Thrift Plan, or Thrift Plan: a tax-qualified 401(k) plan that currently provides for company matching contributions of up to 7% of eligible earnings.
»    Retirement Plan of Marathon Oil Company, or Retirement Plan: a tax qualified defined benefit pension plan.
»    Marathon Oil Company Excess Benefit Plan, or Excess Plan: a nonqualified plan. The defined benefit portion allows participants to accrue benefits above the defined benefit tax limits, and the defined contribution portion allows participants to accrue benefits above the defined contribution tax limits.

MARATHON OIL | EXECUTIVE COMPENSATION 50


»    Marathon Oil Company Deferred Compensation Plan, or Deferred Compensation Plan: a nonqualified plan allowing participants to defer a portion of their compensation and accrue benefits above the Thrift Plan tax limits.
All plans have a three-year vesting requirement for company contributions. All NEOs have met the vesting requirement.
See “Nonqualified Deferred Compensation” below for additional information on the Deferred Compensation Plan and the defined contribution portion of the Excess Plan.
Retirement Plan
In general, all regular full-time and part-time employees in the United States are eligible to participate in the Retirement Plan as of their date of hire.
Benefit accruals are determined under a cash-balance formula, under which plan participants receive pay credits each year equal to a percentage of eligible compensation based on their plan points. Plan points equal the sum of a participant’s age and cash-balance service. Participants with fewer than 50 points receive a 7% pay credit percentage; participants with 50 to 69 points receive a 9% pay credit percentage; and participants with 70 or more points receive an 11% pay credit percentage. Participants are also credited with interest at a rate based on the 30-year Treasury rate with a 3.00% minimum, which in 2021 was 3%.
For 2021, Messrs. Tillman, Whitehead, Wagner and Henderson and Ms. Warnica received pay credits equal to 9% of eligible compensation.
Normal retirement age under the Retirement Plan is age 65. Retirement Plan benefits include various annuity and installment options and a lump sum distribution option.
We have not granted years of service in addition to the service recognized under the terms of our qualified retirement plans (applicable to a broad-based group of employees) to any NEO for purposes of retirement benefit accruals.
Excess Plan - Defined Benefit Portion
The Excess Plan for certain highly compensated employees, including our NEOs, provides benefits that participants would have received under our tax-qualified Retirement Plan but for certain Internal Revenue Code limitations. Eligible compensation under the Excess Plan includes deferred compensation contributions made by NEOs. The Excess Plan also provides an enhancement for officers based on the three highest bonuses earned during their last ten years of employment, instead of the consecutive bonus formula in place for non-officers. Distributions under the Excess Plan are paid in a lump sum following separation from service.
Pension Benefits Table
The following table shows the actuarial present value of accumulated benefits payable to each NEO under the Retirement Plan and the defined benefit portion of the Excess Plan as of December 31, 2021. These values have been determined using actuarial assumptions consistent with those used in our financial statements.

NONQUALIFIED DEFERRED COMPENSATION
We offer certain employees, including our NEOs, the opportunity to accrue benefits equal to the Company matching contributions they would have received under the Thrift Plan but for certain Internal Revenue Code limitations. Officers generally accrue these benefits in the Deferred Compensation Plan, while other employees accrue such benefits in the defined contribution portion of the Excess Plan. Both plans have a three-year vesting requirement for company contributions. All NEOs have met the vesting requirement. Distributions from the Deferred Compensation Plan and the Excess Plan are paid as a lump sum following separation from service.
Deferred Compensation Plan
The Deferred Compensation Plan is an unfunded, nonqualified plan into which a participant may elect to defer up to 20% of his or her eligible compensation each year. Messrs. Wagner and Henderson elected to defer compensation for 2021. Participants are fully vested in their own deferrals under the plan. Additionally, participants can receive company contributions into the plan equal to the maximum potential matching contribution under the Thrift Plan after they have reached defined contribution accruals under the Thrift Plan in excess of tax limits.
The investment options available under the Deferred Compensation Plan generally mirror the core investment options available under the Thrift Plan.
Excess Plan - Defined Contribution Portion
Prior to becoming eligible for participation in the Deferred Compensation Plan, NEOs may have received defined contribution accruals under the Excess Plan. These contributions were available after a participant’s Thrift Plan contributions were limited due to tax requirements and equaled the matching contribution that participants

MARATHON OIL | EXECUTIVE COMPENSATION 52


would have received under the Thrift Plan but for limits imposed by tax law. Defined contribution accruals in the Excess Plan are credited with interest equal to that paid in the “Managed Income Portfolio II” option of the Marathon Oil Company Thrift Plan. The annual rate of return on this option for 2021 was 1.37%.
Nonqualified Deferred Compensation Table

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL
As a matter of policy, we do not enter into employment, severance or change in control agreements with our NEOs. Rather, we provide a Marathon Oil Corporation Officer Change in Control Severance Benefits Plan (Change in Control Plan), which is described in more detail below.
Retirement or Separation
Upon retirement or separation, our NEOs are entitled to receive their vested benefits that have accrued under our broad-based and executive benefit programs. For more information, see “Post-Employment Benefits” and “Nonqualified Deferred Compensation.”
Unvested outstanding equity awards generally forfeit upon a separation from service. Certain of our outstanding equity awards include limited exceptions in connection with retirement. If a NEO retires, unvested restricted stock awards are forfeited, except in the case of mandatory retirement (age 65). Unvested RSU awards will continue to vest based on the original vesting date if a NEO is at least age 60 with five years of service upon separation from service and certain additional requirements are met. Unvested stock options vest if a NEO is at least age 60 with five years of service upon separation from service and certain additional requirements are met. Unvested performance units are forfeited upon a separation from service unless a NEO is at least age 50 with ten years of service, has worked at least half of the performance period and meets certain other requirements, in which case awards may be vested on a prorated basis at the Committee’s discretion.

Death or Disability
In the event of death or disability, our NEOs (or the beneficiary or estate, as defined by the plan terms) would be entitled to vested benefits accrued under our broad-based and executive benefits programs. LTI awards would immediately vest in full upon the death of an NEO, with performance units vesting at the target level. In the event of disability, performance unit awards would generally continue to vest as if the NEO remained actively employed during the period of disability (meaning the NEO has been determined to be disabled under the Company’s long-term disability plan or can provide proof of a Social Security determination of disability). However, for restricted stock/RSUs and stock options, upon termination of employment not for cause while during a period of disability, the awards will immediately vest in full.
Change in Control
To encourage our NEOs to continue their dedication to their assigned duties where a change in control of the Company is under consideration, our Change in Control Plan provides severance benefits if employment is terminated under certain circumstances generally following a change in control.
Under the Change in Control Plan, a change in control generally will have occurred if:
»    Any person not affiliated with Marathon Oil acquires 20% or more of the voting power of our outstanding securities;
»    Our Board no longer has a majority comprised of (1) individuals who were directors on the effective date of the plan and (2) new directors (other than directors who join our Board in connection with an election contest) approved by two-thirds of the directors then in office who (a) were directors on the effective date of the plan or (b) were themselves previously approved by our Board in this manner;
»    We merge with another company and, as a result, our stockholders hold less than 50% of the surviving entity’s voting power immediately after the transaction;
»    Our stockholders approve a plan of complete liquidation of Marathon Oil; or
»    We sell all or substantially all of our assets.
If an NEO was terminated in 2021 without cause or resigned for good reason following a change in control (or prior to a change in control if the NEO reasonably demonstrates that such termination of employment was at the request of actions by a third party who has taken steps reasonably calculated to effect a change in control), he or she would be entitled to the following:
»    a cash payment of up to three times the sum of (1) the NEO’s base salary (as in effect immediately prior to the occurrence of the circumstances giving rise to the termination from employment or, if higher, immediately prior to the change in control) and (2) the greater of (a) the NEO’s annual bonus at target for the year in which the termination from employment occurs or (b) the highest of the annual bonuses paid to the NEO for each of the three years before the termination from employment or, if higher, for each of the three years before the change in control;
»    a cash payment equal to the NEO’s annual bonus at target level multiplied by a fraction equal to the number of days in the bonus calculation year during which the NEO was employed divided by 365; and
»    a cash payment equal to eighteen times the monthly COBRA premium in effect at the NEO’s termination from employment for the level of coverage in which the NEO participated immediately prior to his or her termination from employment.
These benefits are not payable if the termination is for cause (as defined in the Change in Control Plan) or due to mandatory retirement, death, disability or resignation (other than for good reason, as defined in the Change in Control Plan) by the NEO.
The program includes no provisions to reimburse or “gross up” tax obligations following a change in control.

MARATHON OIL | EXECUTIVE COMPENSATION 54


If a change in control occurs prior to the end of a performance period, unvested performance units granted in or prior to 2020 will vest at the applicable performance percentage based on Marathon Oil’s actual relative TSR ending on the last regular trading day immediately prior to the date of the change in control. In such a scenario, unvested performance units granted in 2021 will generally vest at the greater of target performance or the applicable vesting percentage based on actual performance for a performance period ending on the last regular trading day immediately prior to the date of the change in control.
Accelerated vesting of unvested restricted stock, RSUs and stock options granted in or prior to 2020 will occur generally only if an NEO is involuntarily terminated within the two years following a change in control. Accelerated vesting of unvested RSUs granted in 2021 will occur generally only if an NEO is involuntarily terminated or terminates for good reason within the two years following a change in control.
The Change in Control Plan will continue in effect for two years after a change in control.
The following tables assume a termination date or change in control date of December 31, 2021, the last business day of 2021, based on Change in Control Plan terms in effect as of that date. The value of the equity awards (accelerated vesting of restricted stock/RSU awards, stock options and performance unit awards) was calculated using the December 31, 2021 closing market price for our common stock of $16.42 and based on a performance period ending December 31, 2021. The value of performance unit awards assumes that the 2019 performance units would vest and be paid out at 89%, the 2020 performance units would vest and be paid out at 111% and the 2021 TSR performance units and FCF performance units would vest and be paid out at 177% and 200%, respectively.

CEO PAY RATIO
We are providing the following information about the relationship of the annual total compensation of our employees and the annual total compensation of Mr. Tillman, our CEO. The pay ratio included in this information is a reasonable estimate calculated in a manner that is consistent with applicable law, regulatory and other guidance.
PAY RATIO
For our last completed fiscal year, the annual total compensation for our median employee was $128,010. The annual total compensation of our CEO, as reported in the Summary Compensation Table, was $12,997,292. Thus, we estimate that our CEO’s compensation was 102 times the median of the annual total compensation for all of our employees.
METHODOLOGY USED TO IDENTIFY MEDIAN EMPLOYEE
To identify the annual total compensation for all of our employees for purposes of identifying our median employee, we selected October 1, 2021, as our measurement date to allow sufficient time to gather data from the two main payroll systems we use, which are located in the United States and Equatorial Guinea.
The majority of our employees are on our United States payroll, and the compensation used for employees on the United States payroll is compensation that would be reflected in Box 5 of Form W-2 for the period from January 1, 2021 to September 30, 2021.
The compensation used for employees on the Equatorial Guinea payroll reflects pay from December 16, 2020 through September 15, 2021 and includes basic pay, absence pay, overtime amounts, offshore premiums and shift differential payments, as well as annual cash bonus amounts paid on March 15, 2021, and October bonus amounts paid on October 6, 2021. These October bonus amounts were included because they reflect work done prior to October 1, and their inclusion provides Equatorial Guinea payroll information that is more consistent with the measures used for the United States payroll.
These measures of compensation were selected based on our view that each measure provides a reasonable estimate of the comprehensive compensation payments to our employees on each of the relevant payrolls. Taken in the aggregate, we believe this data provides a reasonable estimate of the annual total compensation of all employees of Marathon Oil and its consolidated subsidiaries.
As of October 1, 2021, our total employee population consisted of 1,554 employees working at Marathon Oil and its consolidated subsidiaries, which includes all full-time, part-time and seasonal or temporary employees. Of this total, 1,157 were United States payroll employees, which includes our United States payroll expatriate employees, and 397 were Equatorial Guinea payroll employees.
Using this methodology, we determined that our median employee was a salaried, full-time employee working in the United States.

TRANSACTIONS WITH RELATED PERSONS
We have written procedures for monitoring, reviewing, approving or ratifying related person transactions. We will enter into or ratify related person transactions only when our Board, acting through the Corporate Governance and Nominating Committee, determines that the related person transaction is in the best interests of the Company and its stockholders. The primary features of these procedures are:
»    Each director and executive officer must submit a list of his or her immediate family members, each listed individual’s employer and job title, each firm, corporation or other entity in which such individual is a director, executive officer, partner or principal or in a similar position or in which such person has a five percent or greater beneficial ownership interest, and any profit, non-profit charitable or trade organization for which such individual is actively involved in fundraising or otherwise serves as a director, trustee or in a similar capacity.
»    The Company maintains a list, to the extent the information is publicly available, of five percent beneficial owners and certain information regarding such five percent beneficial owners, including if the owner is an individual, the same information requested of directors and executive officers as noted above.
»    Any related person proposed transaction that involve an amount in excess of $120,000 is submitted to the Corporate Governance and Nominating Committee or the Board at the next regularly scheduled meeting or, in certain cases, to the Committee Chair or other uninterested member of the Corporate Governance and Nominating Committee delegated authority to act on such matters. The facts and circumstances of each proposed related person transaction are reviewed and considered, and a determination is made regarding whether to approve it.
»    Additionally, the Company’s accounts payable, accounts receivable and payroll departments produce quarterly reports of any amounts paid or payable to, or received or receivable from, any related person identified in the lists mentioned above, which are reviewed internally to determine if there are any related person transactions that were not previously approved or ratified. If any such transaction is identified based on this review, it is promptly submitted to the Corporate Governance and Nominating Committee, Committee Chair or other member of the Corporate Governance and Nominating Committee, as appropriate, which reviews the transaction and considers all of the relevant facts and circumstances and a determination is made regarding ratification, modification or termination of the identified transaction. If any such transaction is identified, Internal Audit will perform an evaluation of the Company’s controls and procedures.
»    The Corporate Governance and Nominating Committee annually reviews any previously approved or ratified related person transaction with a remaining term of more than six months or remaining amounts payable to or receivable from the Company of more than $120,000. Based on all relevant facts and circumstances, taking into consideration the Company’s contractual obligations, the Corporate Governance and Nominating Committee determines whether it is in the best interests of the Company and its stockholders to continue, modify or terminate the transaction.
During 2021, there were no transactions in excess of $120,000 between the Company and a related person in which the related person had a direct or indirect material interest.

AUDIT AND FINANCE COMMITTEE REPORT
The Audit and Finance Committee’s purpose is to assist our Board in fulfilling its oversight responsibilities relating to, among other things:
»    the integrity of the Company’s financial statements and financial reporting process and the Company’s systems of internal accounting and financial controls;
»    the engagement of the independent auditor and the evaluation of the independent auditor’s qualifications, independence and performance;
»    the performance of the internal audit function;
»    the Company’s compliance with legal and regulatory requirements; and
»    the Company’s risk management process.
The Audit and Finance Committee is comprised of four directors, each of whom has been determined by our Board to be independent and financially literate under the NYSE’s requirements. The Audit and Finance Committee’s responsibilities are set forth in its charter, available on our website at www.marathonoil.com under About—Board of Directors—Committees and Charters.
Management has primary responsibility for preparing our financial statements and establishing and maintaining our internal control over financial reporting. The Company’s independent auditor is responsible for auditing our financial statements and the effectiveness of our internal control over financial reporting in accordance with standards of the Public Company Accounting Oversight Board (PCAOB), and issuing its reports based on those audits. The Audit and Finance Committee oversees these processes.
In connection with the evaluation, appointment and retention of the independent registered public accountants, the Audit and Finance Committee annually reviews the qualifications, performance and independence of the independent auditor and lead engagement partner and assures the regular rotation of the lead engagement partner as required. In doing so, the Audit and Finance Committee considers a number of factors including, but not limited to: quality of services provided; technical expertise and knowledge of the industry; effective communication; objectivity; and independence. Based on this evaluation, the Audit and Finance Committee has selected PricewaterhouseCoopers LLP (PwC), an independent registered public accounting firm, to audit the Company’s financial statements and the effectiveness of internal control over financial reporting for 2022. In conjunction with the mandated rotation of the lead audit partner, the Audit and Finance Committee and its chairperson are directly involved in the selection of PwC’s lead engagement partner. The current lead engagement partner was selected in 2021, effective for 2022.
We are seeking our stockholders’ ratification of the appointment of PwC to audit the Company’s financial statements and the effectiveness of internal control over financial reporting for 2022 at the Annual Meeting. The Audit and Finance Committee and our Board believe the appointment of PwC as our independent auditor for 2022 is in the Company’s best interests and in the best interests of our stockholders.
The Audit and Finance Committee reviews and pre-approves the fees and expenses of the independent auditor for audit, audit-related, tax and permissible non-audit services. See “Proposal 2: Ratification of Independent Auditor for 2022” for more information on our pre-approval policy.
On February 23, 2022, the Audit and Finance Committee confirmed that in connection with the preparation of the Company’s audited financial statements for the year ended December 31, 2021 and the report on internal control over financial reporting for 2021:
»    The Audit and Finance Committee reviewed and discussed with management the Company’s audited financial statements and its report on internal control over financial reporting for 2021.

MARATHON OIL | AUDIT AND FINANCE COMMITTEE REPORT 58


»    The Audit and Finance Committee met throughout the year with management and PwC, and met with PwC each quarter without the presence of management. The Committee discussed with PwC the matters required to be discussed by the applicable requirements of the PCAOB and the SEC.
»    The Audit and Finance Committee received written communication from PwC, including those related to independence, required by the PCAOB for independent auditor communications with audit committees, and has discussed with PwC that firm’s independence. The Committee has also considered whether PwC’s provision of non-audit services to the Company was compatible with maintaining such independence.
Based on this review and discussion, the Audit and Finance Committee recommended to our Board that the Company’s audited financial statements for the year ended December 31, 2021 and the report on internal control over financial reporting be included in the Company’s Annual Report on Form 10-K for 2021 filed with the SEC.

The Audit and Finance Committee has selected PricewaterhouseCoopers LLP (PwC), an independent registered public accounting firm, to audit the Company’s financial statements and the effectiveness of internal control over financial reporting for 2022. While the Audit and Finance Committee is responsible for appointing, approving compensation for and overseeing the independent auditor’s work, we are requesting, as a matter of good corporate governance, that our stockholders ratify the appointment of PwC as our independent auditor for 2022. PwC served as the Company’s independent auditor during 2021. We believe the appointment of PwC as our independent auditor for 2022 is in the best interests of the Company and our stockholders.
We expect representatives of PwC to be present at the Annual Meeting with an opportunity to make a statement if they would like to do so and to be available to respond to appropriate questions from our stockholders.
