Letter from Our Chairman and
Chief Executive Officer

Dear Stockholders,

On behalf of our entire Board and all of our employees, I want to thank you for your investment in Gilead. This has been a year where Gilead proved its resilience and its strength. When the pandemic struck, we faced multiple challenges. We needed to protect the safety of our employees and contribute our long-standing expertise in antiviral therapies to the fight against COVID-19. At the same time, we had to keep our existing plans on track. I am pleased that we can look back on 2020, knowing that we met all of these challenges and set our company on the path for a strong future.

The entire company rallied to contribute to the work on Veklury. We expanded our manufacturing capability, ran multiple clinical studies and collaborated with many partners to bring the therapy to patients. Veklury became the first FDA-approved therapy for COVID-19 and by the end of 2020, it was being used to treat one in two patients hospitalized in the United States.

Even while delivering Veklury and managing the uncertainties created by the pandemic, Gilead continued to deliver on ongoing commitments to patients. We also significantly strengthened and diversified our portfolio of new medicines. The additions to our portfolio included several new marketed therapies, such as Trodelvy for a type of breast cancer. Gilead’s portfolio now targets an even broader set of unmet medical needs, setting us on a clear path to growth and driving value for our stockholders.

In addition to implementing a number of measures to support our employees and their families through the pandemic, we took many steps to support our ambition of attracting the industry’s best talent. Like many others, we also strengthened our focus on racial equity. This includes dedicated programs for our Black employees and funding for community-based organizations. In a year in which many jobs were lost because of the pandemic, we increased our employee base to more than 13,000 with a particular focus on expanding our expertise in oncology. We hired many talented leaders and welcomed new members to our Board of Directors.

We encourage you to read more about our 2020 performance and ESG-related activities in our Year in Review, which will be available on our website, www.Gilead.com, in early May. We are all very much looking forward to delivering on our new opportunities in 2021, and ensuring Gilead remains a valued contributor to improving global public health.

Sincerely,

Daniel P. O’Day
Chairman and Chief Executive Officer

Letter from Our
Lead Independent Director

Dear Stockholders,

Gilead is committed to improving human health, a mission that has defined and guided my career in the healthcare industry. It has been almost a year since I stepped into my role as Gilead’s Lead Independent Director. During this period, I have worked closely with my fellow directors to ensure effective Board oversight and strong corporate governance practices and involvement. Even with the challenges of 2020, we had the opportunity to engage with many of you during the year and those meetings helped us understand what is important to you. As we approach our Annual Meeting, I would like to highlight several ways the Board has represented your interests.

Board Oversight

As Lead Independent Director, an important part of my role is working with our Chairman and Chief Executive Officer, Daniel O’Day, and the management team on the strategic direction and oversight of the company. We accomplish this by facilitating the Board’s input into major business and organizational initiatives, budgetary considerations, capital allocation priorities and corporate development opportunities. Last year, we worked closely with management on the company’s strategic transactions, including the acquisitions of Forty Seven, Inc., Immunomedics, Inc. and MYR GmbH, as well as key collaborations with Arcus Biosciences, Inc., Pionyr Immunotherapeutics, Inc. and Tizona Therapeutics, Inc.

In 2020, the company remained focused on human capital management, with an emphasis on safety. This was paramount for employees who continued to work at Gilead’s manufacturing facilities and labs during the pandemic. It was also critical to provide support and facilitate productivity for employees working from home.

Gilead established a Global Diversity Council in 2020, chaired by Mr. O’Day, and created Inclusion and Diversity Action Plans focused on attracting, developing and retaining people of diverse backgrounds. We also set and posted two important Diversity Equity and Inclusion goals to reach by 2025: to double the percentage of our Black employees and ensure diverse hires account for at least 15% of all hiring. We are committed to increasing the amount of reporting on our progress in this important area.

In addition, the company’s Corporate Social Responsibility Committee, established in 2018, has helped build accountability for driving social and environmental change across the company by making decisions on CSR-related strategies, stakeholder engagement, reporting, risk mitigation and other relevant activities.

Board Refreshment

As Dan mentioned in his letter, we welcomed four new directors to our Board, who further expand our breadth of academic and healthcare experience. Following the next stockholder meeting, a third of our Board will be female, and of the other Board members, four will be from diverse backgrounds. This makes our Board one of the industry’s most diverse, and is representative of the company’s diverse patient base. I would also like to take this opportunity to thank Per Wold-Olsen and Richard J. Whitley, MD, two long-standing directors who have made extraordinary contributions to Gilead’s growth and development and are departing this year.

On behalf of the Board, I thank you for your investment in Gilead. I am proud of all that the company accomplished in 2020 and look forward to the work we will continue to do to bring new medicines to people with significant unmet needs.

Kevin E. Lofton
Lead Independent Director

	Proposal 1

	Election of Directors There are nine nominees for the Board positions presently authorized. Proxies cannot be voted for a greater number of persons than the number of nominees standing for election. Directors are elected by a majority of the votes cast (number of shares voted “for” a director must exceed the number of shares voted “against” that director) with respect to the election of each director at the Annual Meeting. Each director who is elected will hold office until the next annual meeting of stockholders and until his or her successor is elected and qualified, or until such director’s earlier death, resignation or removal. Each nominee listed below is currently a director of Gilead and, other than Jeffrey A. Bluestone, Ph.D., Javier J. Rodriguez and Anthony Welters, was previously elected by the stockholders at the 2020 annual meeting of stockholders. Dr. Bluestone, Mr. Rodriguez and Mr. Welters were each recommended for consideration to our Nominating and Corporate Governance Committee by a third-party search firm and joined our Board in June 2020, October 2020 and December 2020, respectively. Richard J. Whitley, M.D., and Per Wold-Olsen are retiring effective at the Annual Meeting, and our Board size will be reduced from eleven to nine members effective after the conclusion of the Annual Meeting, provided that our director nominees are elected by stockholders at the Annual Meeting. Shares represented by executed proxies will be voted for or against the election of the nine nominees named below. In the event that any nominee should be unable or, for good cause, unwilling to serve as a director, such shares will be voted for the election of such substitute nominee as our Board may propose or the Board may reduce the size of the Board. Each person nominated for election has agreed to serve if elected and our Board and management have no reason to believe that any nominee will be unable to serve. Our Nominating and Corporate Governance Committee recommended each of the nominees listed below to our Board for nomination. Each member of our Nominating and Corporate Governance Committee meets the criteria of “independent director” as specified by applicable listing rules of Nasdaq and our Board Guidelines, as determined affirmatively by our Board.
		Our Board unanimously recommends a vote FOR each named director nominee:
		Jacqueline K. Barton, Ph.D. Jeffrey A. Bluestone, Ph.D. Sandra J. Horning, M.D.	Kelly A. Kramer Kevin E. Lofton Harish Manwani	Daniel P. O’Day Javier J. Rodriguez Anthony Welters

The Gilead Board of Directors

Evaluating Director Candidates

In evaluating candidates for membership on the Board, our Nominating and Corporate Governance Committee considers the candidate’s relevant experience, the number and nature of other board memberships held and possible conflicts of interest. Each year, our Nominating and Corporate Governance Committee reviews its Board membership criteria and assesses the composition of the Board against the criteria. Our Nominating and Corporate Governance Committee also will consider all factors it determines appropriate to meeting the needs of the Board at that particular time. According to the Board membership criteria established by our Nominating and Corporate Governance Committee, candidates nominated for election or reelection to the Board should possess the following qualifications:

►	the highest standards of personal and professional integrity;
►	the ability and judgment to serve the long-term interest of our stockholders;
►	experience and expertise relevant to our business and that will contribute to the overall effectiveness and diversity of the Board;
►	broad business and social perspective;

Corporate Governance

►	the ability to communicate openly with other directors and to meaningfully and civilly participate in the Board’s decision-making process;
►	commitment to serve on the Board for an extended period of time to ensure continuity and to develop knowledge about our business and willingness to devote appropriate time and effort to fulfilling the duties and responsibilities of a Board member;
►	independence from any particular constituency; and
►	the ability and willingness to objectively appraise the performance of management.

	OUR COMMITMENT TO INCLUSION AND DIVERSITY
	Diversity is an important attribute of a well-functioning board. Our Nominating and Corporate Governance Committee advises our Board on matters of diversity, including race, gender, culture, thought and geography, and nominates director candidates that will enhance the Board’s mix of viewpoints, backgrounds, skills, experience and expertise. Our Nominating and Corporate Governance Committee seeks to include diverse candidates in any director search and specifically requests diverse candidates from our third-party search firm. In addition to the traditional candidate pool of corporate directors and officers, the committee also considers qualified candidates from a broad array of organizations, including academic institutions, privately held businesses, nonprofit organizations and trade associations. In 2017, our Board amended the Nominating and Corporate Governance Committee Charter to formalize our Board’s commitment to diversity. If our director nominees are elected by stockholders at the Annual Meeting: ►A third of our Board will be female, and of the other Board members, four will be from diverse backgrounds. ►Our Lead Independent Director and the chairs of all of our Board committees will be female or from diverse backgrounds.

In identifying potential director candidates, our Nominating and Corporate Governance Committee considers candidates recommended through a variety of methods and sources. These include suggestions from current Board members, senior management, stockholders, professional search firms and other sources. Our Nominating and Corporate Governance Committee reviews all candidates in the same manner regardless of the source of the recommendation.

It is the policy of our Nominating and Corporate Governance Committee to consider properly submitted stockholder recommendations of new director candidates. Our Nominating and Corporate Governance Committee’s evaluation process for director nominees does not vary based on whether a candidate is recommended by a stockholder or the Board. Any stockholder recommendation must include the candidate’s name and qualifications for Board membership, the candidate’s age, business address, residence address, principal occupation or employment, the number of shares beneficially owned by the candidate and all other information that would be required to solicit a proxy under federal securities law. In addition, the recommendation must include the stockholder’s name, address and the number of shares beneficially owned. The recommendation should be sent to the Corporate Secretary, Gilead Sciences, Inc., 333 Lakeside Drive, Foster City, California 94404. The recommendation must be delivered to the Corporate Secretary prior to the same deadline for director nominations not for inclusion in the proxy materials, as described under question 16 in “Questions and Answers.”

Our New Directors in 2020

In 2020, we continued our ongoing efforts to refresh our Board by welcoming four new directors who provide a breadth of academic and healthcare industry experience and skills that complement our other Board members.

Independence of the Board of Directors

The Nasdaq listing rules require that a majority of the members of a listed company’s board of directors qualify as “independent” as affirmatively determined by our Board. In addition, our Board Guidelines require that a substantial majority of our Board consist of “independent” directors as defined by the Board Guidelines. Our Board Guidelines are available on our website at www.gilead.com on the Investors page under “Corporate Governance.”

After a review of all relevant transactions and relationships between each director, as well as his or her family members, and us, our senior management and independent registered public accounting firm, our Board has determined that eight of our nine nominees for director are “independent” directors as specified by applicable laws and regulations of the SEC, the listing rules of Nasdaq and our Board Guidelines. In addition, the Board previously determined that Dr. Whitley and Mr. Wold-Olsen were independent. Mr. O’Day, our Chairman of the Board, is not an independent director because he is currently an executive officer of the company.

Majority Vote Standard for Election of Directors

Our bylaws require directors to be elected by a majority of the votes cast with respect to such director in uncontested elections (number of shares voted “for” a director must exceed the number of shares voted “against” that director). In a contested election (a situation in which the number of nominees for director exceeds the number of directors to be elected), the standard for election of directors will be a plurality of the shares voting in the election of directors at any such meeting at which a quorum is present. Under our Board Guidelines, any director who fails to receive at least a majority of the votes cast in an uncontested election must tender his or her resignation to our Board. Our Nominating and Corporate Governance Committee would then evaluate the tendered resignation and make a recommendation to our Board to accept or reject the resignation or to take other action. Our Board will act on our Nominating and Corporate Governance Committee’s recommendation and publicly disclose its decision and the rationale for such decision within 90 days from the date the election results are certified. The director who tenders his or her resignation will not participate in our Board’s decision. If a nominee who was not already serving as a director does not receive at least a majority of the votes cast for such director at the annual meeting, that nominee will not become a director.

Our Board’s Role and Responsibilities

Corporate Governance

We are committed to strong corporate governance structures and practices that reflect our commitment to integrity, accountability and excellence in conducting our business. Our Board has adopted certain corporate governance principles, which are set forth in our Board Guidelines and other key governance documents, to set forth a framework for how the Board, its various committees and individual directors should perform their functions. These principles are designed to drive effective functioning of the Board in its oversight role and to promote the interests of stockholders. Our Board regularly reviews and updates our governance materials in light of legal and regulatory requirements, evolving best practices and other developments. In considering possible modifications of our corporate governance structures and practices, our Board focuses on those changes that are best for our company and our business. Our focus is on advancing the long-term interests of our company, our stockholders and our other stakeholders. This Proxy Statement includes a summary of our corporate governance practices. Additional information regarding our governance framework and associated governance documents, including our Board Guidelines, are available at www.gilead.com on the Investors page under “Corporate Governance.”

Oversight of Corporate Strategy

Our Board actively oversees management’s establishment and execution of corporate strategy, including major business and organizational initiatives, annual budget and long-term strategic plans, capital allocation priorities, financial results and potential corporate development opportunities. Our Board regularly receives information and formal updates from our management and actively engages with the senior leadership team with respect to the implementation of our corporate strategy at Board meetings and throughout the year. Our independent directors also hold regularly scheduled executive sessions during which they review and discuss our corporate strategy. Consistent with our corporate transaction approval policy, our Board also, directly or indirectly through a committee, reviews and approves strategic transactions that are material to our business, including significant acquisitions and collaborations.

	OVERSIGHT OF COVID-19 RESPONSE Our Board dedicated time during its meetings to actively monitor and advise on both our internal and external response to the pandemic, which included: ►Deploying significant resources to rapidly develop and scale up the production and global supply of Veklury, the first treatment for COVID-19 approved by the FDA ►Requiring flexible location employees to work from home while implementing site enhancements and risk protocols (including health screenings, COVID-19 testing and reconfiguration of work and common spaces to allow for social distancing) for employees who needed to be physically present for their positions ►Providing ongoing support for community partners and grant programs, including the creation of the global CARES (COVID-19 Acute Relief and Emergency Support) Grantee Fund to provide financial support to grantees facing imminent closure or termination of vital services due to the pandemic (which provided up to $20 million in donations to these groups) For additional details, see “Our Ongoing Response to COVID-19” on pages 7-8.

Oversight of Risk

Our Board exercises its risk oversight responsibility directly and through its committees. Our Board considers specific risk topics directly, including, but not limited to, risks associated with our company’s strategic plan and risks relating to pricing strategies of newly approved products. Our Board has delegated responsibility to its committees for oversight of specific risks that fall within the committee’s areas of responsibility. Each of the committees periodically reports to the Board on its risk oversight activities. In addition to receiving reports from our Board committees, our Board periodically reviews reports from Gilead’s management of specific material risks or legal developments. We believe our Board’s leadership structure effectively supports the Board’s independent evaluation and management of risk.

Audit Committee		Compensation and Talent Committee		Nominating and Corporate Governance Committee
Oversees risks associated with our financial and accounting systems, accounting policies and investment strategies, in addition to finance-related public reporting, regulatory compliance (other than healthcare compliance) and certain other matters delegated to the Committee, including risks associated with our information systems and technology (including cybersecurity).		Oversees risks related to our compensation policies and practices to help ensure that these policies and practices do not incentivize employees to take unnecessary or excessive risks that are reasonably likely to have a material adverse effect on Gilead as well as risks related to the talent management and succession planning of our executive officers.		Oversees risks related to corporate governance matters and certain other non-financial or non-compensation-related risks, including, but not limited to, Gilead’s compliance program, clinical trials, manufacturing, healthcare compliance, political contributions (including payments to trade associations) and ESG matters.

Oversight of Human Capital Management

Our Board believes that human capital management, including inclusion and diversity initiatives, talent development and succession planning, are vital to Gilead’s continued success. In 2020, our Board amended the Compensation and Talent Committee charter to expressly delegate the Compensation and Talent Committee oversight responsibility of our strategies and policies related to human capital management, including with respect to matters such as inclusion and diversity, workplace environment and culture, talent recruitment, development and retention and employee engagement and effectiveness. Our Compensation and Talent Committee receives regular updates from our management regarding human capital management matters throughout the year.

Our Board also is actively involved in talent development and succession planning for our senior management team and provides guidance on important decisions in each of these areas. The Board receives leadership from our Lead Independent Director as well as our Compensation and Talent Committee regarding these matters. Under its amended charter, the Compensation and Talent Committee has responsibility for overseeing and making recommendations to our Board with respect to talent management and succession planning for the Chief Executive Officer and our other executive officers. In connection with these efforts, our Compensation and Talent Committee also performs a formal evaluation of the performance of our senior leadership team on an annual basis.

	INCLUSION AND DIVERSITY IN 2020 We believe that an inclusive and diverse workforce is critical to enabling our mission and implementing our corporate strategy, and the Board remained focused on guiding our efforts to advance inclusion and diversity in our workforce and promote racial equity within our company and in our community. As a result, in 2020: ►We established a Global Diversity Council, chaired by our Chairman and Chief Executive Officer, which is responsible for governance of inclusion and diversity matters, including tracking progress on our goals and promoting a culture of inclusion. ►We created Inclusion and Diversity Action Plans focused on attracting, developing and retaining diverse talent. ►We adopted an Advancing Black Leadership strategy designed to provide opportunities for existing employees and increasing representation through external recruitment. ►We announced goals to double the percentage of Black employees at Gilead and having diverse hires account for at least 15% of all hiring by 2025.

Oversight of Environmental, Social and Governance Matters

Investing in our ESG program is a core part of our global citizenship and reflects our values of accountability, inclusion, teamwork, excellence and integrity. We believe our commitment to corporate social responsibility will enable us to execute on our mission of providing innovative medicines to prevent and treat life-threatening illnesses in a way that is socially responsible and environmentally sustainable. As we move forward together, we will continue to focus on our impact beyond medicine to support our communities and meet our significant responsibilities to society as a whole.

Our Nominating and Corporate Governance Committee has primary responsibility for oversight of ESG matters and receives regular reports from our CSR Committee on our ESG program. Our CSR Committee, which is comprised of key members of management, manages our ESG program and, in consultation with our senior leadership team, sets and implements strategy, reporting and other initiatives to advance our program. In 2020, we completed an enterprise-wide materiality assessment that identified five material topics that will be prioritized in our ESG efforts: 1) Pricing, Access and Affordability of Medicines; 2) Research and Development for Unmet Medical Needs; 3) Inclusion and Diversity; 4) Employee Recruitment, Development and Retention; and 5) Climate Change. For additional information regarding our ESG program, including an overview of other key achievements, see “Our Environmental, Social and Governance (“ESG”) Program” on page 9.

Oversight of Cybersecurity Matters

Our Audit Committee has primary responsibility for overseeing risks associated with our information systems and technology, including cybersecurity. Our Audit Committee receives quarterly reports from our Head of Information Security, Risk and Compliance and an annual report from our Chief Information Officer regarding our company’s information systems and technology and associated policies, processes and practices for managing and mitigating cybersecurity and technology-related risks. As part of our risk mitigation program, we provide annual information security training for our employees. We also provide additional specialized trainings for our Security Operations team and employees with access to certain sensitive information systems. In addition, we engage a third-party advisory firm to review our security controls and maturity against the National Institute of Standards and Technology (NIST) cybersecurity framework. We also have entered into information security risk insurance policies for certain of our operating subsidiaries. We have not experienced any material information security breaches, including within the last three years, which reflects our commitment to maintaining the integrity and security of our systems and technology.

Stockholder Communications with Our Board

Stockholders may communicate with our Board by sending a letter to the Corporate Secretary, Gilead Sciences, Inc., 333 Lakeside Drive, Foster City, California 94404. Our Corporate Secretary reviews all communications from stockholders, but may, in his sole discretion, disregard any communication that he believes is not: related to our business; within the scope of our responsibility; credible; or material or potentially material.

If deemed an appropriate communication, the Corporate Secretary will submit the stockholder communication to the member of our Board addressed in the communication and to our Lead Independent Director. We maintain a “Stockholders Communications with the Board” policy that outlines the applicable procedures and is available on our website at www.gilead.com on the Investors page under “Corporate Governance.”

Board Structure

Board Leadership

Daniel P. O’Day CHAIRMAN OF THE BOARD Mr. O’Day was appointed as our Chief Executive Officer and Chairman of the Board, effective March 1, 2019. Our Board believes that it is currently in the best interests of Gilead and its stockholders for Mr. O’Day to serve as our Chief Executive Officer and Chairman of the Board because it positions Mr. O’Day to effectively drive future strategy and decision-making for our organization. In addition to public, private and non-profit board experience, Mr. O’Day has a track record of success in highly scientific and competitive therapeutic areas, deep understanding of the evolving healthcare environment around the world and unwavering commitment to driving innovation across all aspects of the business. As the individual with primary responsibility and accountability for managing our day-to-day operations, Mr. O’Day can provide unified leadership of Gilead and ensure that key business and strategic issues, risks and opportunities are brought to our Board’s attention in a way that prioritizes and makes the best use of our Board’s time.

Kevin E. Lofton LEAD INDEPENDENT DIRECTOR In May 2020, our Board unanimously appointed Kevin E. Lofton as our new Lead Independent Director, in recognition of his leadership, in-depth knowledge of Gilead and demonstrated commitment to our mission. Having served on our Board since 2009, Mr. Lofton has a deep knowledge of our business operations. He also has significant leadership experience on other public boards and in the healthcare industry, including experience serving as a chief executive officer and a board member of several large organizations. In addition, Mr. Lofton has demonstrated a commitment to improving access to healthcare, particularly for underserved communities. Given his proven leadership capability, breadth of industry experience and business success, our Board believes Mr. Lofton is a strong and effective partner to our Chairman of the Board.

Our Board Guidelines provide that the independent directors will designate a Lead Independent Director when the Chairperson is not an independent director. The role of Lead Independent Director at Gilead is modeled on the role of an independent Chairperson, ensuring a strong, independent and active Board of Directors. Our Board regularly reviews its leadership structure to evaluate whether it remains appropriate for our company, and we continue to believe the robust duties of our Lead Independent Director empower our independent directors to provide guidance and oversight of management. As set forth in the Lead Independent Director Charter, the Lead Independent Director has clearly delineated and comprehensive duties, which are described further below:

Board Evaluations

Our Board believes that a robust and constructive Board and committee evaluation process is an essential component of board effectiveness. Our Board and each of the committees conduct an annual evaluation, which includes an assessment by each director of the performance of our Board and the committees on which the director sits, and a discussion of Board performance among each director, our Lead Independent Director and our Chairperson. The evaluation process is organized by our Nominating and Corporate Governance Committee and led by our Lead Independent Director. The results of the evaluation process are shared with our full Board.

	DEVELOPMENT OF ANNUAL EVALUATION PROCESS		WRITTEN QUESTIONNAIRES		ONE-ON-ONE DISCUSSIONS		EVALUATION OF RESULTS
	►Our Nominating and Corporate Governance Committee develops an annual self-evaluation process and prepares the questionnaires for our Board and the committees.		►Each director completes a written questionnaire.		►Our Lead Independent Director and our Chairperson have one-on-one discussions with each director.		►Our Lead Independent Director consolidates the feedback and shares the results with our full Board for discussion and consideration.

Certain Relationships and Related Person Transactions

Indemnity Agreements

We have entered into indemnity agreements with each of our executive officers (including our Named Executive Officers) and directors that provide, among other things, that we will indemnify such officer or director, under the circumstances and to the extent provided for therein, for expenses, damages, judgments, fines and settlements he or she may be required to pay in actions or proceedings to which he or she is or may be made a party by reason of his or her position as a director, officer or other agent of us, and otherwise to the full extent permitted under Delaware law and our bylaws.

Policies and Procedures

Related Person Transactions

Our Audit Committee is responsible for reviewing and approving, in advance, all related person transactions. Related persons include any of our directors or executive officers, certain of our stockholders and their immediate family members, and transactions include any transaction or arrangement in which the amount involved exceeds $120,000 and where the company or any of its subsidiaries is a participant and a related person has a direct or indirect material interest. In reviewing and approving any such transactions, our Audit Committee considers all relevant facts and circumstances, including, but not limited to, whether the transaction is on terms comparable to those that could be obtained in an arm’s length transaction with an unrelated third party and the extent of the related person’s interest in the transaction. The responsibility for reviewing and approving such transactions is set forth in writing in the Audit Committee Charter. A copy of the Audit Committee Charter is available on our website at www.gilead.com on the Investors page under “Corporate Governance.”

To identify related person transactions, each year we submit and require our directors and officers to complete Director and Officer Questionnaires identifying any transactions with us in which the executive officer or director or their immediate family members have a material interest.

Conflicts of Interest

We review related person transactions due to the potential for a conflict of interest. A conflict of interest occurs when an individual’s private interest interferes, or appears to interfere, with our interests. In addition, our Nominating and Corporate Governance Committee determines, on an annual basis, which members of our Board meet the definition of independent director under the criteria specified by applicable laws and regulations of the SEC, the listing rules of Nasdaq and our Board Guidelines. The obligation for this determination is set forth in writing in the Nominating and Corporate Governance Committee Charter. A copy of the Nominating and Corporate Governance Committee Charter is available on our website at www.gilead.com on the Investors page under “Corporate Governance.” Our Nominating and Corporate Governance Committee reviews and discusses any relationships with directors that would potentially interfere with his or her exercise of independent judgment in carrying out the responsibilities of a director.

2020 Related Person Transactions and Conflicts of Interest

In 2020, there were no related person transactions or conflicts of interest. Approval of any related person transaction or conflict of interest would require approval of the applicable Board committee (as described above) or the full Board.

Code of Ethics

Our Code of Ethics establishes the corporate standards of behavior for all our employees, officers and directors and sets our expectations of contractors and agents. The Code of Ethics is available on our website at www.gilead.com on the Investors page under “Corporate Governance.” Our Code of Ethics requires any person who becomes aware of any departure from the standards in our Code of Ethics to report his or her knowledge promptly to a supervisor or an attorney in the legal department.

Compensation of Non-Employee Board Members

The members of our Board play a critical role in guiding our strategic direction and overseeing our management. In recent years, the evolving role and responsibilities of a public company board have increased the time commitment required for, and risks associated with, board service. As a result, the demand for highly qualified and experienced individuals who are capable of serving as the directors of a large public company has also increased.

Table of Contents

Corporate Governance

These dynamics make it imperative that we provide a competitive compensation program for our non-employee directors. Such directors are accordingly compensated based upon their respective levels of Board participation and responsibilities, including service on Board committees, and receive a combination of annual cash retainers and equity compensation in the form of stock options and restricted stock unit awards. In addition, our non-employee directors are also reimbursed for their business-related expenses incurred in connection with attendance at Board and committee meetings and related activities. Our employee directors do not receive additional compensation for their service on our Board.

Our Compensation and Talent Committee reviews our non-employee director compensation program on an annual basis with its independent advisor. Any recommended changes to the program are then presented to the independent members of our Board for their consideration and approval.

Our non-employee directors are compensated through annual equity awards under a pre-established grant-date fair value formula and annual cash retainers for Board and Board committee service.

Cash Payments and Equity Awards

The following table sets forth the compensation arrangements for our non-employee Board members during 2020:

		2020 Non-Employee Board Member Compensation
					Grant-Date Value of Equity Awards(2)
		Cash Payment	(1)		Options(4)		Restricted Stock Units(4)
All Non-Employee Board Members		$75,000 retainer			$ 150,000		$150,000
Lead Independent Director		$40,000/ $75,000	(3)		None		None
		additional cash retainer
Audit Committee Chair		$20,000			None		None
		additional cash retainer
Compensation and Talent Committee Chair		$15,000			None		None
		additional cash retainer
Nominating and Corporate Governance Committee Chair		$15,000			None		None
Science Committee Chair		additional cash retainer
Committee Member		$20,000			None		None
(in addition to any Committee Chair fees)		additional cash retainer
		for each committee

(1)	A non-employee Board member’s actual annual cash retainer will be equal to the aggregate of his or her retainer fee for Board service ($75,000) plus his or her retainers for service on one or more Board committees (e.g., if the Audit Committee Chair also serves as a member on the Compensation and Talent Committee, the total dollar amount of the cash retainer will be $135,000).
(2)	The number of shares of our common stock subject to the option portion of the annual equity award will be calculated as follows: $150,000 divided by [(closing market price per share of our common stock on the grant date) multiplied by (Black-Scholes option-valuation percentage)], with any fractional share rounded down to the next whole share. The number of shares of our common stock subject to the restricted stock unit portion of the annual equity award will be calculated by dividing $150,000 by the closing market price per share of our common stock on the award date, with any fractional share rounded down to the next whole share.
(3)	The Lead Independent Director will receive an additional retainer of $75,000 should the Lead Independent Director not serve on any committees of the Board or $40,000 should the director serve on a committee (in addition to any retainer amounts for committee service).
(4)	The Lead Independent Director, committee chairs and other committee members do not receive any additional equity awards for their Lead Independent Director or committee service.

Deferred Compensation Plan

Our Deferred Compensation Plan allows our non-employee directors to defer all or a portion of their cash retainer each year. The deferred amount may either be immediately converted into phantom shares of our common stock or invested in a designated group of investment funds, neither of which results in above-market interest under disclosure rules. To the extent that a non-employee director elects to defer his or her cash retainer into phantom shares, the resulting number of phantom shares of our common stock will be determined by dividing the deferred amount by the fair market value per share of our common stock on the conversion date. The resulting number of phantom shares will be paid out in actual shares of our common stock at the end of the deferral period. If the non-employee director elects to defer his or her retainer into investment funds, then he or she may select from among the investment funds available under the Deferred Compensation Plan. These investment funds are substantially the same as those available under our broad-based Section 401(k) employee savings plan.

Corporate Governance

A non-employee director may elect to receive his or her deferred account balance at a designated age that is no earlier than age 50 and no later than age 75, or on the date of his or her cessation of Board service or on the second or fifth anniversary of that cessation date, in a lump sum or in annual installments not to exceed 10 years. An early distribution is permitted in the event of a financial hardship. In the event of death, an account balance will be distributed in a lump sum to the director’s designated beneficiary.

Stock Ownership Guidelines

We have stock ownership guidelines to encourage our non-employee directors to retain a significant portion of their shares of our common stock. These stock ownership guidelines require our non-employee directors to hold shares of our common stock with an aggregate fair market value equal to or greater than five times their annual retainer. This guideline is to be achieved over a five-year period, measured from the date the non-employee director first joins our Board. As of December 31, 2020, all members of our Board were in compliance with our stock ownership guidelines or within the grace period for compliance.

Terms of Equity Awards

The stock options granted to our non-employee directors have an exercise price equal to the fair market value per share of our common stock on the date of grant (based on the closing market price for our common stock on that date as reported on the Nasdaq Global Select Market). Each option has a maximum term of 10 years, subject to earlier termination three years after the non-employee director’s cessation of Board service. Each option vests in successive equal quarterly increments over a one-year period, measured from the date of grant. The restricted stock unit awards granted to our non-employee directors vest upon the completion of one year of Board service measured from the date of grant. Initial equity awards for new non-employee directors are prorated based on the number of days remaining in the compensation period in which they commence Board service. The shares that vest under restricted stock unit awards may, pursuant to a director’s advance election, be subject to a deferred issuance in up to five annual installments following his or her cessation of Board service.

The table below summarizes the compensation paid by us to our non-employee Board members for the 2020 fiscal year:

	Proposal 2

	Ratification of the Selection of Independent Registered Public Accounting Firm Our Audit Committee has selected Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2021 and has further directed that we submit the selection of our independent registered public accounting firm for ratification by the stockholders at the Annual Meeting. Ernst & Young LLP has audited our financial statements since our inception in 1987.
		Our Board unanimously recommends a vote “FOR” Proposal 2.

Annual Evaluation and Selection of Independent Auditor

To help ensure continuing auditor independence, our Audit Committee annually reviews Ernst & Young LLP’s independence and performance in connection with the Committee’s determination of whether to retain Ernst & Young LLP or engage another firm as our independent auditor. In the course of these reviews, our Audit Committee considers, among other things:

►	Ernst & Young LLP’s historical and recent performance on the Gilead audit;
►	Ernst & Young LLP’s institutional knowledge and expertise regarding Gilead’s global business, accounting policies and practices and internal control over financial reporting;
►	the professional qualifications of Ernst & Young LLP, the lead audit partner and other key engagement partners;
►	Ernst & Young LLP’s disclosures related to audit quality and performance, including recent Public Company Accounting Oversight Board (the “PCAOB”) inspections;
►	the appropriateness of Ernst & Young LLP’s audit fees, including the fees that Ernst & Young LLP receives for non-audit services;
►	the quality and candor of Ernst & Young LLP’s communications with the Audit Committee and management; and
►	the potential impact of changing our independent registered public amounting firm.

Based on this evaluation, our Audit Committee has determined that Ernst & Young LLP is independent and that it is in the best interest of Gilead and its stockholders to continue to retain Ernst & Young LLP to serve as our independent auditors for the 2021 fiscal year.

Rotation of Lead Audit Partner

The Audit Committee requires the lead audit partner to be rotated at least every five years. The process for selection of Gilead’s lead audit partner pursuant to this rotation involves a meeting between the Chair of our Audit Committee and the candidate for the role as well as discussion by the full Audit Committee and management. Our last rotation of lead audit partner was in 2018.

Principal Accountant Fees and Services

Our Audit Committee is responsible for audit firm compensation. The aggregate fees billed by Ernst & Young LLP for the years ended December 31, 2020 and 2019 for the professional services described below are as follows:

		2020			2019
Audit Fees(1)		$	9,362,000		$	8,342,000
Audit-Related Fees(2)		$	—		$	4,000
Tax Fees(3)		$	984,000		$	2,092,000
All Other Fees(4)		$	7,000		$	67,000
Total		$	10,353,000		$	10,505,000

(1)	Represents fees incurred for the integrated audit of our consolidated financial statements and of our internal control over financial reporting and review of the interim condensed consolidated financial statements, as well as fees incurred for audit services that are normally provided by Ernst & Young LLP in connection with other statutory or regulatory filings or engagements.
(2)	Represents fees incurred for assurance and related services that are traditionally performed by Ernst & Young LLP, are reasonably related to the performance of the audit or review of our consolidated financial statements and are not reported under “Audit Fees.” These fees included accounting consultation services primarily related to implementation of new accounting standards and fees incurred in connection with specified procedures performed by Ernst & Young LLP in relation to user-defined reports.
(3)	Represents fees primarily incurred in connection with domestic and international tax compliance and tax consultation services.
(4)	Represents fees incurred in providing miscellaneous permitted advisory services and accessing Ernst & Young LLP’s online research database in 2020 and 2019.

All of the services described above were pre-approved by our Audit Committee. The Committee concluded that the provision of these services by Ernst & Young LLP would not affect their independence.

Pre-Approval Policy and Procedures

To minimize relationships that could impair the objectivity of Ernst & Young LLP, our Audit Committee adopted policies and procedures for the pre-approval of audit and permissible non-audit services rendered by Ernst & Young LLP. Under this policy, our Audit Committee must pre-approve all services provided by Ernst & Young LLP, and the policy prohibits the engagement of Ernst & Young LLP for certain specified services. The policy permits the engagement of Ernst & Young LLP for services approved by our Audit Committee in defined categories such as audit services, audit-related services and tax services. The policy also permits engagement of Ernst & Young LLP for other services approved by our Audit Committee if there is a persuasive business reason for using Ernst & Young LLP over other providers. The policy provides that, as a general rule of thumb, the fees for these other services should be less than 25% of total audit fees. Pre-approval may be given as part of our Audit Committee’s approval of the scope of Ernst & Young LLP’s engagement or on an explicit case-by-case basis before Ernst & Young LLP is engaged to provide each service. The pre-approval of services may be delegated by our Audit Committee to a member of the Audit Committee. Our Audit Committee receives quarterly reports on the scope of services provided to date and planned to be provided by Ernst & Young LLP in the future.

Representatives of Ernst & Young LLP are expected to be present at our Annual Meeting, will have an opportunity to make a statement if they so desire and are expected to be available to respond to appropriate questions from stockholders.

Stockholder ratification of the selection of Ernst & Young LLP as our independent registered public accounting firm is not required by our bylaws or otherwise. However, our Board is submitting the selection of Ernst & Young LLP to the stockholders for ratification as a matter of good corporate practice. If the stockholders fail to ratify the selection, our Audit Committee will reconsider whether or not to retain Ernst & Young LLP. Even if the selection is ratified, our Audit Committee may direct the appointment of a different independent registered public accounting firm at any time during the year if they determine that such a change would be in the best interests of Gilead and our stockholders.

Audit Committee Report

Our Audit Committee is composed of four directors and operates under a written charter adopted by the Board of Directors. Our Board has determined that all members of our Audit Committee are “independent” directors under the criteria specified by applicable laws and regulations of the SEC, the listing rules of Nasdaq and our Board Guidelines.

Our Audit Committee oversees, on behalf of our Board, our corporate accounting, financial reporting process and systems of internal accounting and financial controls. Management has the primary responsibility for the financial statements, the reporting process, and the system of internal control over financial reporting.

Our Audit Committee is responsible for the selection, appointment, retention, compensation and oversight of Gilead’s independent registered public accounting firm, Ernst & Young LLP. Our Audit Committee reviewed and discussed with Ernst & Young LLP the auditors’ independence from Gilead and its management. As part of that review, we received the written disclosures and the letter required by applicable requirements of the Public Company Accounting Oversight Board (the “PCAOB”) regarding Ernst & Young LLP’s communications with the Audit Committee concerning independence, and our Audit Committee discussed Ernst & Young LLP independence from Gilead. We also considered whether Ernst & Young LLP’s provision of non-audit services to Gilead is compatible with the auditor’s independence.

We adopted auditor independence policies and procedures for the pre-approval of audit and permissible non-audit services rendered by Ernst & Young LLP. The policy permits the engagement of Ernst & Young LLP for services approved by our Audit Committee in defined categories such as audit services, audit-related services and tax services. The policy also permits engagement of Ernst & Young LLP for other services approved by our Audit Committee if there is an appropriate business reason for using Ernst & Young LLP over other providers. Our Audit Committee receives quarterly reports on the scope of services provided to date and planned to be provided by Ernst & Young LLP in the future.

Our Audit Committee has reviewed and discussed the audited consolidated financial statements for the year ended December 31, 2020 with management and Ernst & Young LLP. Our Audit Committee has reviewed and discussed with Ernst & Young LLP the matters required to be discussed with the Audit Committee by the applicable requirements of the PCAOB and the SEC.

Based upon these reviews and discussions, the Audit Committee recommended to our Board of Directors that the audited consolidated financial statements be included in Gilead’s Annual Report on Form 10-K for the year ended December 31, 2020 filed with the SEC. Our Board has approved this inclusion.

	Proposal 3

	Advisory Vote to Approve the Compensation of Our Named Executive Officers Based upon a vote of stockholders at our 2020 annual meeting of stockholders, and following our Board’s recommendation for an annual advisory vote to approve the compensation of the Named Executive Officers, we are providing stockholders with an advisory vote to approve the compensation of our Named Executive Officers. Although the vote is non-binding, our Board and Compensation and Talent Committee value the opinions of our stockholders and will consider the outcome of the vote when making future compensation decisions affecting our executive officers. We encourage our stockholders to read the Compensation Discussion and Analysis, beginning on page 46, which describes the details of our executive compensation program and the decisions made by the Compensation and Talent Committee in 2020. Our 2020 corporate achievements are described under “Corporate Performance Metrics and Achievements for 2020” in the Compensation Discussion and Analysis. Our stockholders are being asked to approve by advisory vote the following resolution relating to the compensation of the Named Executive Officers in this Proxy Statement: “RESOLVED, that Gilead’s stockholders hereby approve the compensation paid to Gilead’s executive officers named in the Summary Compensation Table of this Proxy Statement, as that compensation is disclosed pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, the various compensation tables and the accompanying narrative discussion included in this Proxy Statement.” The vote on this resolution is not intended to address any specific element of compensation; rather the vote relates to the compensation of the Named Executive Officers, as described in this Proxy Statement in accordance with the compensation disclosure rules of the SEC.

Compensation Discussion and Analysis

This Compensation Discussion and Analysis provides an overview of the components of our executive compensation program and the 2020 decisions of the Compensation and Talent Committee of our Board of Directors (our “Compensation and Talent Committee” or “Committee”) for our 2020 Named Executive Officers, who were:

Daniel P. O’Day Chairman and Chief Executive Officer (Chief Executive Officer)		Andrew D. Dickinson Chief Financial Officer		Johanna Mercier Chief Commercial Officer		Merdad V. Parsey, M.D., Ph.D. Chief Medical Officer		Brett A. Pletcher Executive Vice President, Corporate Affairs and General Counsel

2020 Key Program and Policy Changes

Our Board believes compensation should be targeted competitively relative to peers, with a significant emphasis on performance-based compensation. Each year, the Compensation and Talent Committee reviews our compensation programs to evaluate the alignment with our business strategy and compensation philosophy and to incorporate stockholder feedback. Based on this review, the Committee made two major program changes in 2020:

►	In January 2020, the Committee approved a more formulaic annual incentive plan design with more objective and rigorous annual performance metrics for the 2020 plan year.

	INCREASED FOCUS ON FINANCIAL SUCCESS		INCREASED ALIGNMENT WITH OUR STRATEGIC OBJECTIVES		ENHANCED RISK MITIGATION
	►Increased the weighting of financial metrics from 30% to 50% of the total award ►Established threshold, target and maximum achievement levels for each of our financial metrics ►Introduced a Non-GAAP Operating Income metric		►50% of the award is tied to rigorous, pre-established pipeline, product and people metrics ►Removed the +/-10% factor that was previously included in the annual incentive plan for unplanned accomplishments		►Subjected awards to clawback/forfeiture for misconduct ►Authorized our Compensation and Talent Committee to exercise negative discretion to reduce earned payouts for all participants, including for lapses in compliance

►

In March 2020, our Board amended our clawback policy to (1) expand its scope to cover significant misconduct by executive officers resulting in the violation of a significant company policy, law or regulation that causes material financial, operational or reputational harm to Gilead, including the failure to appropriately supervise a subordinate employee who engaged in misconduct, and (2) require public disclosure of actions taken to recoup compensation if the underlying facts have been disclosed.

Fiscal 2020 was a highly unusual year for Gilead; however, our strong performance was a clear reflection of the solid underlying strength of our business.

Advancing Veklury, the first FDA-Approved COVID-19 Treatment. In response to the pandemic, we advanced Veklury (remdesivir) through clinical trials, ramping up manufacturing, coordinating with governments and the public, and receiving U.S. Food and Drug Administration (FDA) approval in October. The rapid development and distribution of Veklury during 2020, a process that would typically take several years, required enormous effort and attention from our executives and employees around the world. At the beginning of the pandemic, we had enough Veklury to treat a few thousand patients. By the end of December 2020, we had increased our manufacturing capacity to be able to treat more than 1 million patients in 2020 and millions more in 2021. Veklury had, and has, a significant impact on patients worldwide, improving the time to recovery by 5 days. With hospitals often at maximum capacity during the pandemic, Veklury’s ability to improve clinical outcomes in hospitalized patients, including shortening the length of hospitalization time, provided tremendous relief to the global healthcare infrastructure.

Growing HIV Products Despite Headwinds. We saw sales of our HIV products grow 3% compared with the prior year, even as we lost exclusivity for Atripla^® and Truvada^® in Q4 and felt the impacts of the pandemic as people delayed visits to healthcare providers. Biktarvy continues to stand out in the HIV treatment market, with growth of 53% compared to 2019. In HIV prevention, we ended the year with a 46% U.S. market share for Descovy, exceeding our goal of 40%.

Delivering Opportunities in New Therapeutic Areas Through Strategic Growth: In 2020, we entered into 18 new acquisitions and partnerships, transforming and growing our pipeline by 50% (as measured by asset-indication projects) and setting us on a clear path to bring innovation to patients in the future, over the near- and long-term. With respect to progress against strategic initiatives, we added a number of key commercial products and investigational drug candidates at various stages of development that will help us accelerate our oncology portfolio. We also added critical internal expertise, made key external hires and added employees through acquisitions.

►	Forty Seven, Inc. With the acquisition of Forty Seven in April, we gained magrolimab, a potential first-in-class CD47 inhibitor that is being developed for both hematological malignances and solid tumors.
►	Immunomedics, Inc. With the acquisition of Immunomedics in October, we added Trodelvy, which already has accelerated approval for the treatment of adult patients with metastatic triple-negative breast cancer who have received at least two prior therapies for metastatic disease. Trodelvy also has the potential to help patients with other solid tumor types, including urothelial cancer, lung cancer and other breast cancers. Positive data from the ASCENT study were presented at the European Society of Medical Oncology meeting in September and have been filed with the FDA in support of full approval of the medicine.
►	We entered into several key partnerships, including agreements with Arcus Biosciences, Inc., Tizona Therapeutics, Inc. and Pionyr Immunotherapeutics, Inc., which provide us with optionality to license in future drug candidates, while minimizing our risk.

Beyond those gained through partnerships and acquisitions, we advanced internal candidates, including Kite’s cell therapy treatment, Tecartus. In July, the FDA granted accelerated approval to Tecartus, the first and only approved chimeric antigen receptor (CAR) T cell therapy for the treatment of adult patients with relapsed or refractory mantle cell lymphoma.

Achieving Financial Results That Position Us for Long-Term Shareholder Growth. We achieved net product revenues of $24.4 billion and non-GAAP operating income of $11.7 billion, exceeding our original targets of $22.1 billion and $10.6 billion respectively, reflecting the uptake of Veklury and Biktarvy’s role as the leading treatment for HIV. Veklury and Biktarvy helped and will continue to help offset the loss of exclusivity for Atripla and Truvada, as well as the ongoing impact of the pandemic on our HIV and HCV medicines. Revenue is a key driver of our long-term value creation as it is reinvested in research and development, and strategic acquisitions and partnerships. These investments provide us with a strong portfolio that allows us to remain selective and invest where there is highest potential value. As the result of our strong fiscal 2020 financial performance, we are well positioned to continue to execute on our strategic priorities of delivering on opportunities in new areas, maintaining our leadership in antivirals, and prioritizing and executing across our portfolio.

Although our business was impacted by the pandemic, the Committee elected to maintain our original incentive goals and structure; we made no changes to our compensation programs due to COVID-19, we provided no special compensation arrangements, and we did not apply any positive or negative discretion to incentive payouts. Annual incentives were earned above target due to our strong financial and operational performance in 2020, while performance equity awards granted in 2018 vested below target, reflecting the impact of continued uncertainty around the pandemic on our stock price.

Stockholder Engagement and 2020 Vote on Named Executive Officer Compensation

At the 2020 annual meeting of stockholders, approximately 83% of the shares present voted in favor of the compensation of our named executive officers. Our Compensation and Talent Committee carefully reviews voting results and feedback from our stockholder engagement activities when making executive compensation decisions. During 2020, we contacted stockholders representing approximately 58% of our outstanding shares, to engage on executive compensation, governance, and corporate strategy matters. Based on our conversations with stockholders in 2020, it was clear that the lower than usual stockholder approval for our executive compensation was the result of elevated executive compensation during 2019 resulting from the one-time make-whole payments for our Chairman and Chief Executive Officer, Daniel O’Day.

			Since our 2020 Annual Meeting, we met with stockholders representing approximately 52% of our outstanding shares. During these meetings, we discussed key corporate governance topics and asked our stockholders for perspectives and feedback on our executive compensation program. Our Lead Independent Director also met with stockholders representing approximately 38% of our outstanding shares, compared to 27% the prior year.

In an effort to be responsive to feedback from our stockholders in 2019, in January 2020 the Compensation and Talent Committee proactively approved a new annual incentive plan design, which included increasing the financial metrics from 30% to 50% of the total award. The Committee also adopted rigorous performance metrics that were more formulaic than in previous years and eliminated the Committee’s discretion to increase or decrease the incentive payout by 10% for unplanned events. In addition, our Board amended our clawback policy to expand its scope. During our stockholder engagement meetings following our annual shareholder meeting in 2020 we took the opportunity to discuss the proactive changes to provide greater transparency in our short-term incentive plan and the expansion of our clawback policy. Our stockholders expressed no serious concerns regarding our pay programs and our Compensation and Talent Committee determined that no further changes were necessary in response to the voting results at our 2020 stockholder meeting.

Stockholders may express their views directly to our Compensation and Talent Committee as described in our “Stockholder Communications with the Board” policy, available on our website at www.gilead.com on the Investors page under “Corporate Governance.”

Compensation Overview

Elements of Annual Compensation

Our Compensation and Talent Committee annually reviews our Named Executive Officers’ compensation, payment criteria, pay outcomes and goals. Based on this review, the Committee believes our executive compensation program is fair and delivers pay that is aligned with stockholder returns.

A summary of our Named Executive Officers’ annual compensation awarded or earned during 2020 is set forth below:

Executive Compensation

Pay and Performance Alignment

Our industry’s business model is characterized by significant capital investment, long lead times for discovery and development and unpredictable outcomes due to the nature of developing medicines for human use.

Our business involves multi-year development cycles, in which the return on investments in our product pipeline may take up to 12 years or more. Thus, our executive compensation program focuses not only on the successful progression of research programs, clinical trials and the launch of new products, but also on performance across a range of shorter-term metrics that advance our long-term strategy and longer-term value creation for our stockholders. As a result of long development cycles, success in the early phases of development, while critical to achieving our long-term strategy and short-term goals, may not be reflected in our operating performance and share price until several years in the future.

Our long-term equity incentives, awarded in the form of performance share units, stock options and restricted stock units, align executives’ compensation directly with revenue and TSR performance. As a result, a substantial portion of the target total direct compensation (“TDC”) for each Named Executive Officer is at-risk and tied directly to Gilead’s performance with an appropriate balance between the short- and long-term, as shown below. Target TDC comprises annual base salary, target annual incentive, and target annual long-term equity incentives based on their grant date fair values.

CHIEF EXECUTIVE OFFICER	OTHER NAMED EXECUTIVE OFFICERS (AVERAGE)

In aggregate, target TDC for our Named Executive Officers approximated the median of our peers. However, target pay opportunity is not representative of actual realized pay unless we perform. For example:

►	As of December 31, 2020, all the stock options granted to our Named Executive Officers over the past four years were underwater, or “out of the money.”
►	In addition, our performance share units that vested over the same period, paid out below target.

To illustrate the alignment of our executive compensation program with stockholder value, the following table compares the average 2018 long-term equity incentive (“LTI”) target grant value to the average 2020 realized value for our Named Executive Officers who received a 2018 award⁽¹⁾ and shows that only 30% of the target value was delivered or realizable.

Named Executive Officers’ 2020 Annual Compensation

Base Salaries

Our Compensation and Talent Committee reviews and approves our Chief Executive Officer’s base salary, subject to ratification by the independent members of our Board of Directors. In approving the salary increase for Mr. O’Day, our Compensation and Talent Committee considered his performance and leadership, peer practices and advice from the Committee’s independent consultant.

Annual base salary increases for other Named Executive Officers were recommended by Mr. O’Day and approved by the Committee effective as of March 1, 2020. Ms. Mercier received an increase based on her performance, market positioning and internal equitability. Base salaries for the others were unchanged.

The 2020 base salaries for our Named Executive Officers were as follows:

Named Executive Officer		2020 Base Salary			% Base Salary Increase
Mr. O’Day		$	1,650,000		3.1	%
Mr. Dickinson(1)		$	950,000		0.0	%
Ms. Mercier		$	1,025,000		2.5	%
Dr. Parsey(1)		$	1,000,000		0.0	%
Mr. Pletcher(1)		$	950,000		0.0	%

(1)	Mr. Dickinson and Mr. Pletcher received a salary increase, effective November 1, 2019 in recognition of their new roles and therefore did not receive an increase in 2020. Dr. Parsey was not eligible for a salary increase in 2020 due to his November 1, 2019 hire date.

Executive Compensation

Annual Incentive

In January 2020 the Compensation and Talent Committee proactively approved a new annual incentive plan design, which included increasing the financial metrics from 30% to 50% of the total award. The Committee also adopted rigorous performance metrics that were more formulaic than in previous years and eliminated the Committee’s discretion to increase or decrease the incentive payout by 10% for unplanned events.

Our annual incentive plan focuses on short-term financial, pipeline, product and people metrics, that serve as building blocks for our future product development and position us to deliver longer term value to stockholders. Our annual incentive plan is designed to complement our long-term equity program, which more directly aligns realized executive compensation with our longer-term share price performance.

In 2020, our Chief Executive Officer’s annual incentive was tied solely to our corporate performance, with our Chief Executive Officer’s individual performance goals being the same as our corporate performance metrics. Our other Named Executive Officer’s annual incentive were based on the achievement of the same corporate performance metrics that applied to our Chief Executive Officer, as well as individual performance goals which differ from the corporate performance metrics, with award amounts determined by the following formula:

Both the Company Performance Factor and Individual Performance Factor can range from 0% to 150% achievement, with the maximum cash incentive payout capped at 200% of target.

Target Annual Incentive Opportunities
The 2020 target annual incentive opportunities for our Named Executive Officers were established as a percentage of their base salaries, as set forth below, which were the same percentages established for the prior year. Actual earned amounts could range from 0% to 200% of the target opportunity, based on achievement of the relevant performance objectives.

Named Executive Officer	2020 Target Cash Incentive Opportunity (as a percentage of base salary)
Mr. O’Day	150	%
Mr. Dickinson	100	%
Ms. Mercier	100	%
Dr. Parsey	100	%
Mr. Pletcher	100	%

Corporate Performance Metrics and Achievements for 2020
Our Compensation and Talent Committee reviewed our performance for 2020 against pre-established performance metrics. The metrics were established in January 2020 after careful consideration of key short-term financial, pipeline, product and people goals. While our business was considerably impacted by the COVID-19 pandemic, the committee determined that the goals set at the beginning of the year remained the best measures of our performance. Based on our performance, the Committee calculated a corporate performance factor between 0% and 150% achievement for each of the metrics, as shown below. If the overall corporate performance factor for the year was less than 50%, no award would have been earned.

Net product revenue and non-GAAP operating income comprise 50% of the corporate performance factor because they drive our ability to invest in and advance our pipeline. For 2020, the net product revenue goal was set slightly lower than actual performance ($22,119M) in the prior year due to the anticipated impact of the loss of exclusivity for Atripla and Truvada in Q4.

Overall Corporate Performance Factor 138%

Based on the achievements described above, our Compensation and Talent Committee certified an overall corporate performance factor of 138% of target, determining that no positive or negative adjustments were necessary. In addition to the achievements noted above, we engaged in substantial efforts to complete the accelerated development, manufacturing and distribution of Veklury to patients in need around the world, while continuing to focus on our core HIV business and cell therapy business. Our financial

performance overall and specifically under our annual incentive plan corporate performance factor reflected strong uptake of Veklury as the result of the team’s dedication and effort. This helped to offset the impact of the pandemic on our HIV and HCV portfolio, due to fewer patients seeking treatment. We also maintained strong operating margins, resulting in strong cash flows that will allow us to continue to advance and expand our pipeline, not only internally but through investing in transformational medicines through the 18 strategic partnerships and acquisitions completed in 2020. These accomplishments position Gilead for strong shareholder value creation in the future.

Individual Performance Objectives

Our Compensation and Talent Committee also considered the individual contributions of our Named Executive Officers (other than our Chief Executive Officer, whose annual incentive opportunity was based entirely on corporate performance) to the achievement of the research and development, commercial, financial and operational objectives that supported our corporate goals. Individual performance objectives are determined and communicated to executives at the beginning of the year. The individual performance factors noted below could range from 0% to 150% and reflect the extent to which each Named Executive Officer’s personal contributions were determined to benefit our overall performance and to exceed or fall short of the officer’s individual objectives for the year. The table below summarizes select 2020 achievements for each Named Executive Officer. In addition to these achievements, each Named Executive Officer played a significant role in delivering Veklury to patients globally. This unexpected focus required enormous effort and attention from each Named Executive Officer as we advanced Veklury through clinical trials in record time, scaled a very complex manufacturing and supply chain process and received U.S. Food and Drug Administration approval as a treatment for patients hospitalized with COVID-19. The typical time to bring a pharmaceutical product to market is around seven to nine years, yet we were able to achieve this in less than a year, in addition to achieving and exceeding all planned objectives.

Executive Officer		Select 2020 Achievements		Individual Performance Factor
Mr. Dickinson		►In 2020, Mr. Dickinson restructured and built out the CFO leadership team, hiring a mix of internal and external talents for critical roles. He initiated multiple transformational initiatives across the CFO organization which will drive long term efficiencies and cost savings for the organization. ►Under Mr. Dickinson’s leadership, we executed 18 strategic partnerships and acquisitions including the transformational acquisitions of Immunomedics, Inc. and Forty-Seven, Inc., secured a variety of options and opt-ins with Arcus, Pionyr and Tizona, and restructured the Galapagos agreement. ►In addition, in his first year as CFO, Mr. Dickinson effectively led the organization through the uncertainty created by the COVID-19 pandemic including bringing Veklury to market, engaging with our investors through significant, unpredictable changes to our financial guidance.		130%
Ms. Mercier		►Since her appointment as Chief Commercial Officer, Ms. Mercier has driven efficiency and made significant progress in evolving the global commercial organization to support global product launches and market penetration. ►Ms. Mercier successfully led the Commercial organization through the highly complex allocation and distribution of Veklury. ►Despite the impact of the pandemic on our business, under Ms. Mercier’s leadership we saw 3% growth in sales across our HIV franchise in 2020, compared with the prior year, despite the Atripla and Truvada Loss of Exclusivity.		140%
Dr. Parsey		►Dr. Parsey was instrumental in establishing a new governance model for the portfolio focused on driving value through prioritization. Under this new model, he enabled a >50% expansion of our pipeline with high value programs by re-prioritizing programs of less value. ►Under Dr. Parsey’s leadership, our portfolio has expanded significantly in Oncology, notably with the additions of magrolimab and Trodelvy. Our Oncology portfolio now consists of both marketed therapies, such as Trodelvy, and programs across various states of the pipeline. There are currently 27 internal, ongoing clinical-stage programs for hematological malignancies and solid tumors. ►In response to the pandemic, Dr. Parsey directed the efforts to gain regulatory approval of Veklury in record time.		130%
Mr. Pletcher		►Mr. Pletcher was instrumental in managing Gilead’s extensive and global public affairs, government affairs and legal activities related to developing, manufacturing and distributing Veklury throughout 2020. ►Mr. Pletcher’s legal oversight was key in enabling us to execute on the 18 strategic partnership and acquisitions in 2020. ►Under Mr. Pletcher’s leadership, our public affairs, government affairs, legal and compliance functions delivered on key initiatives, including favorable outcomes related to federal regulations and government investigations, advancement and recognition of Gilead’s ESG efforts and launching Gilead’s Creating Possible rebranding.		130%

Long-Term Equity Compensation

Our long-term equity compensation program is designed to link our Named Executive Officers’ pay with the long-term interests of our stockholders, competitively position our executives, and provide meaningful retentive value, as supported by a thorough analysis of peer practices. Consistent with 2019, our Compensation and Talent Committee granted performance shares, stock options and restricted stock units, as shown below:

2020 Performance Share Awards

TSR Percentile vs. Comparator Group		% of Target Paid
81st or above		200%
50th		100%
20th or below		0%

If our absolute TSR is negative, the vesting opportunity is capped at 100% of target, regardless of our relative performance. To receive the earned shares, an executive officer must generally remain employed with us through the date when our Compensation and Talent Committee certifies performance achievement.

Absolute Revenue Portion. One-third of the revenue-based performance shares is tied to achievement of our 2020 net product revenue goal, one-third is tied to a 2021 net product revenue goal and one-third is tied to a 2022 net product revenue goal. Each year’s net product revenue goal is established by our Compensation and Talent Committee in the first quarter of that year, and the payout level can range from 0% to 200% of the target allocated to each year’s goal. Revenue is a key objective used in both our short- and long-term incentive plans due to our historically high margin commercialized products and the strategic importance of investments within research and development. Revenue allows us to invest in research and development which is necessary for long-term growth. The uncertainty of many external factors that influence our business and industry, such as unanticipated pricing pressures, product-approval timing and volatility in the foreign currency exchange rates, make it difficult to forecast net product revenue beyond a one-year period. As a result, our Compensation and Talent Committee has determined that the current design appropriately measures performance over the long-term, as it provides line of sight for our executive officers while making the value of awards earned contingent on three-year absolute TSR performance. In January 2020, our Compensation and Talent Committee established the net product revenue performance goal of $22.1 billion (at target) for 2020. The same 2020 net product revenue performance goal also applies to one-third of the revenue-based performance shares granted in 2019 and 2018.

Our Compensation and Talent Committee believes that stock options provide an appropriate incentive for our executives because they will realize value only if our stock price appreciates, which benefits all stockholders. Stock options granted to our Named Executive Officers vest over a four-year service period. One-quarter of the shares of our common stock subject to these options vests one year from the grant date and the remaining shares vest in equal quarterly installments thereafter (assuming the continued service of the executive officer over the next three years).

2020 Restricted Stock Units

Our Compensation and Talent Committee believes that restricted stock units promote long-term retention and alignment with shareholders. Restricted stock units granted to our Named Executive Officers vest over a four-year service period. One-quarter of the shares subject to these awards vest one year from the grant date and the remaining shares vest in equal annual installments thereafter (assuming the continued service of the executive officer over the next three years).

2018 Performance Share Awards Earned

In January 2018, our Compensation and Talent Committee granted to our then-current Named Executive Officers performance share awards, that were subject to a three-year performance period and continued employment through certification of performance achievement:

►	The vesting requirement for the first tranche was tied to our relative TSR for the performance period from February 1, 2018 through December 31, 2020, compared to the TSR of the companies comprising the S&P Healthcare Sub-Index over such period; and
►	The vesting requirement for the second tranche was based on net product revenue goals established for each of 2018, 2019 and 2020 (one-third each year).

Executive Compensation

In January 2021, our Compensation and Talent Committee certified final performance achievements for the 2018 performance share awards. While our operational and financial accomplishments in 2020 position us for long-term shareholder value creation, our total shareholder returns have been affected by the uncertainty around the pandemic as well as the fact that our portfolio contains several early-stage assets that have yet to be reflected in the price. Our three-year relative TSR was at the 9.60^th percentile, resulting in a payout of 0% of target for the TSR-based awards. Our net product revenue exceeded the target revenue goal in 2018, 2019 and 2020, resulting in a payout of 163.4% of target for the revenue-based awards. Based on our TSR and three-year revenue achievements the 2018 performance awards paid out at 81.7% of target. This was the fourth consecutive year that our performance share awards paid out below target. To see the alignment of these 2018 performance share awards with stockholder value, please see the chart on page 52.

Executive Compensation

Other Executive Compensation Policies and Practices

Role of Chief Executive Officer

Our Chief Executive Officer makes recommendations to our Compensation and Talent Committee with respect to the compensation for our Named Executive Officers other than himself. In formulating his recommendations, our Chief Executive Officer reviews internal base salary data and external compensation data provided by our Human Resources Department. The Human Resources Department has engaged Compensia Inc. (“Compensia”), a national compensation consulting firm, to provide comparable market data, including tally sheets, financial performance reports, market compensation reviews and other analyses to aid our Chief Executive Officer in developing his recommendations. During 2020, Compensia served solely as a consultant to management in the compensation decision-making process. When setting 2020 compensation levels, our Compensation and Talent Committee placed considerable weight on our Chief Executive Officer’s compensation recommendations because of his direct knowledge of each Named Executive Officer’s performance and contributions.

Role of Compensation Consultant

Our Compensation and Talent Committee has retained Frederic W. Cook & Co., Inc. (“FW Cook”), a national compensation consulting firm, as its independent compensation consultant. FW Cook reports directly to our Compensation and Talent Committee, which has the direct authority to appoint, compensate, oversee the work of and dismiss its compensation consultant. George Paulin, Chairman of FW Cook, attends meetings of our Compensation and Talent Committee, as requested. FW Cook provides various executive compensation services to our Compensation and Talent Committee, including advising our Compensation and Talent Committee on the principal aspects of our Chief Executive Officer’s compensation and evolving industry practices, and providing market information and analyses regarding the competitiveness of our program design for both our executive officers and the non-employee members of our Board. During 2020, FW Cook served solely as a consultant to our Compensation and Talent Committee and did not provide any other services to Gilead.

Our Compensation and Talent Committee has determined that FW Cook is independent and the work of FW Cook on behalf of our Compensation and Talent Committee did not raise any conflict of interest based on the six factors for assessing independence and identifying potential conflicts of interest as set forth in Exchange Act Rule 10C-1(b)(4), the listing standards of Nasdaq and such other factors as were deemed relevant under the circumstances.

Use of Market Data

Individual compensation levels and opportunities for our Named Executive Officers are compared to a peer group of biopharmaceutical and pharmaceutical companies headquartered in the United States that are most similar to us in terms of business strategy, labor market competition, market capitalization, revenue and number of employees. Our compensation peer group for 2020, which was identified based on these objective selection criteria and remained unchanged from our compensation peer group for 2019, comprised these 10 companies:

Compensation Peer Group
AbbVie Inc.		Biogen Inc.	Eli Lilly and Company	Pfizer Inc.
Allergan plc		Bristol Myers Squibb Company	Johnson & Johnson
Amgen Inc.		Celgene Corporation	Merck & Co., Inc.

The following chart represents our position relative to our peer group on three key selection criteria at the time the 2020 compensation peer group was approved in July 2019 (based on publicly available information as of May 2019).

		Revenue in $ Millions (as of May 31, 2019)			Market Capitalization in $ Millions (as of May 31, 2019)
Peer Group Median		$	24,217		$	106,993
Gilead Sciences, Inc.		$	22,320		$	82,879

Executive Compensation

Our compensation peer group includes industry competitors we believe are most like us in terms of business complexity and product life cycle. We also include companies that fall within specified revenue and market capitalization ranges. These ranges are broad enough to ensure we can maintain a sufficient number of peer companies. This is especially important as our industry experiences a number of mergers and acquisitions each year, thereby reducing the number of relevant peer company choices. Our Compensation and Talent Committee reviews the companies in our compensation peer group annually and makes adjustments as necessary so that the comparator companies properly reflect the market in which we compete for executive talent. We also review the executive pay practices of similarly situated companies as reported in industry surveys and reports. In practice, our Compensation and Talent Committee has not targeted a specific percentile relative to our compensation peer group for individual components of our total compensation. Instead, we take a holistic perspective in establishing total compensation for our executive officers, considering internal pay equity that recognizes officers’ relative experience, responsibilities and individual capabilities in addition to external market compensation practices.

Use of Tally Sheets

Our Compensation and Talent Committee annually reviews tally sheets in its evaluation of the total compensation provided to each Named Executive Officer. These tally sheets estimate dollar amounts for each compensation component, including current cash compensation (base salary and annual incentive), outstanding vested and unvested equity awards, employee benefits, perquisites and other personal benefits and potential severance payments and benefits.

Nonqualified Deferred Compensation

Eligible employees (including our executive officers) can enroll in our Deferred Compensation Plan and defer a portion of their base salaries and part or all their annual incentives and commissions. Gilead generally does not provide any matching contributions to the Deferred Compensation Plan; however, to compensate for pension benefits Mr. O’Day forfeited with his previous employer when he joined Gilead, we agreed as part of the negotiations over his offer letter to credit a $750,000 employer contribution to Mr. O’Day’s individual deferred compensation account for each of the first five years of his service. Each participant may direct the investment of his or her deferred compensation account balance into investment choices that mirror substantially all the investment funds available under the Gilead’s 401(k) plan. None of these investment alternatives result in “above-market” interest for disclosure purposes. For further information on the deferred compensation arrangements of our Named Executive Officers, see the 2020 Nonqualified Deferred Compensation table on page 74.

Benefits and Perquisites

We provide medical and other benefits to our executive officers that are generally available to other full-time employees, including participation in our employee stock purchase plan, a group term life insurance plan and a Section 401(k) savings plan. Under the 401(k) plan, we make matching contributions on behalf of each participant equal to 100% of his or her contributions to the plan, up to an annual maximum matching contribution of $15,000. All our 2020 Named Executive Officers participated in the 401(k) plan during 2020 and received matching contributions.

We do not provide defined benefit retirement plans, post-retirement health coverage or any other supplemental retiree benefits for our executive officers or employees. We generally do not provide perquisites or other personal benefits to our executive officers.

For further information on the perquisites and other personal benefits provided to our Named Executive Officers during 2020, see the Summary Compensation Table on pages 67-68.

Stock Ownership Guidelines

We have stock ownership guidelines that require each Named Executive Officer to maintain a stock ownership level equal to a specified multiple of his or her annual base salary, as set forth in the table below:

STOCK OWNERSHIP GUIDELINE (AS MULTIPLE OF BASE SALARY)

Individuals newly hired or promoted are allowed a specified number of years to comply with their ownership guidelines. As of December 31, 2020, all our Named Executive Officers complied or were within the grace period for compliance with their applicable stock ownership guidelines.

Executive Compensation

Clawback Policy

In March 2020, our Board amended our clawback policy. Our Board believes the company’s executives should be financially responsible for misconduct covered by our “clawback” policy, under which the Compensation and Talent Committee has authority to recoup any cash incentive payments, performance-based equity compensation or certain proceed realized from other equity-based compensation from an executive officer whose misconduct contributed to Gilead’s obligation to file a financial restatement. The Committee also has authority to recoup all or any portion of the amounts or shares of stock (including proceeds realized on a sale of such shares) attributable to cash or equity-based incentive compensation from any executive officer whose significant misconduct results in a violation of significant company policy, law or regulation that caused material financial, operational or reputational harm to Gilead, including the failure to appropriately supervise a subordinate employee who engaged in misconduct.

Our policy requires the company to publicly disclose actions taken to recoup compensation from an executive so long as the underlying facts have been previously disclosed, subject to certain legal and privacy rights considerations

The Board has multiple mechanisms to enforce the clawback policy, including

1.	Withholding or recouping cash incentive payments under our annual incentive plan;
2.	Cancelling outstanding unvested performance shares, which would otherwise vest at the end of a three-year performance period;
3.	Cancelling outstanding unvested stock options or RSUs which would otherwise generally vest over four years; and
4.	Recovering the proceeds realized from the sale of shares of Company stock issued under any equity-based incentive during or with respect to the period during which the misconduct occurred.

Hedging and Pledging Prohibitions

We maintain an insider trading policy which, among other provisions, prohibits our directors and all employees, including our Named Executive Officers, from engaging in transactions that hedge Gilead securities, including through the use of financial instruments such as prepaid variable forwards, equity swaps, collars and exchange funds, and that prohibits derivative securities transactions related to Gilead securities, including put or call options.

Severance Benefits

We maintain the Gilead Sciences, Inc. Severance Plan, as amended and restated effective May 5, 2020 (the “Severance Plan”) that offers severance payments and benefits to all our employees, including our executive officers, upon certain involuntary terminations of employment. The intent of our Severance Plan is to serve the following purposes:

►	Enable us to provide a standard set of payments and benefits to new and current executive officers and employees.
►	Align the interests of our executive officers with those of our stockholders by enabling our executive officers to consider corporate transactions that are in the best interests of our stockholders and other stakeholders without undue concern over whether a transaction may jeopardize their employment.
►	Assure our executive officers of fair treatment in connection with a change in control of Gilead by providing for payments and benefits under the Severance Plan subject to a “double trigger,” which means that an executive officer will be eligible to receive payments and benefits under the plan in connection with a change in control of Gilead only if he or she incurs a qualifying termination of employment.

In addition, the Severance Plan does not provide “gross-up” payments on any excise tax imposed on any change in control benefits.

Compensation-Related Risk

Our Compensation and Talent Committee and its independent consultant, with input from our Human Resources Department, annually reviews the compensation program to determine whether it encourages excessive risk-taking that would create a material risk to the company’s economic viability. As part of this review, our Compensation and Talent Committee specifically considers (i) the balance of the program including the appropriate mix of short- and long-term goals and incentives; (ii) whether the appropriate controls and governance policies are in place to manage risk; and (iii) whether broad-based employee incentive plans (including sales plans) have appropriate leverage and do not drive undue risk taking.

Executive Compensation

Based on this annual review, our Compensation and Talent Committee concluded it was not reasonably likely that any of our compensation policies and practices in place during 2020, whether individually or in aggregate, would have a material adverse effect upon Gilead. As discussed in prior years, our Compensation and Talent Committee considered the following factors:

►	Our overall compensation structure is applied uniformly throughout the organization, with the only major exception relating to the form in which equity compensation is awarded.
►	For our broad-based employee population with a title of Senior Director or higher, a significant component of compensation is in the form of equity awards tied to the value of our common stock.
►	The vesting of performance share awards is tied to our relative TSR and revenue achievement over prescribed performance periods.
►	Our overall compensation structure is not excessively oriented toward short-term incentives, which are less leveraged than plans used by our peers.
►	The performance goals for our 2020 annual incentive program were based on both financial and non-financial corporate measures as well as individual performance (except with respect to our Chief Executive Officer, whose performance is evaluated solely on corporate measures).
►	Our stock ownership guidelines require our executive officers to maintain a substantial ownership interest in Gilead.
►	Our expanded clawback policy permits us to recoup cash incentives and equity awards paid to our executive officers if financial results have to be subsequently restated as a result of their misconduct or our executive officers engage in significant misconduct resulting in a violation of significant company policy, law or regulation that caused material financial, operational or reputational harm to Gilead, including the failure to appropriately supervise a subordinate employee who engaged in misconduct.
►	Hedging transactions in our common stock, such as put and call options or pre-paid forward sale contracts by executive officers, employees and directors, as well as pledging of our securities, are not allowed under our insider trading policy.

For the foregoing reasons, our Compensation and Talent Committee has concluded that it was not reasonably likely that our overall employee compensation structure, when analyzed either in terms of its company-wide application or its specific application to our various major business units, would have a material adverse effect upon Gilead.

Tax Deductibility of Compensation

Section 162(m) of the Internal Revenue Code disallows a tax deduction to public companies for compensation more than $1 million that is paid to certain current or former executive officers. Following repeal of an exception to this $1 million limitation for performance-based compensation, the Compensation and Talent Committee determined to maintain performance-based compensation arrangements, subject to such discretion as the Committee may determine appropriate. As a result of amendments to Section 162(m), we expect that compensation paid to our Named Executives Officers more than $1,000,000 generally will not be deductible.

Compensation and Talent Committee Report⁽¹⁾

Our Compensation and Talent Committee has reviewed and discussed the Compensation Discussion and Analysis required by Item 402(b) of Regulation S-K and contained within this Proxy Statement with management and, based on such review and discussions, our Compensation and Talent Committee recommended to our Board of Directors that the Compensation Discussion and Analysis be included in this Proxy Statement.

Executive Compensation

Severance and Change in Control Arrangements with Named Executive Officers

Although the employment of the Named Executive Officers is “at will,” they are eligible to receive certain severance payments and benefits upon their termination of employment under certain defined circumstances. There are four general categories of termination:

►	Voluntary Termination/For Cause Termination: includes a voluntary termination of employment by the Named Executive Officer (other than in connection with a resignation for Good Reason) prior to reaching applicable retirement age and a termination of the Named Executive Officer’s employment by us for Cause.
►	Retirement: includes a termination of employment by the Named Executive Officer after reaching applicable retirement age, other than a termination of the Named Executive Officer’s employment by us for Cause.
►	Involuntary Termination Without Cause/Good Reason Resignation: includes a termination of the Named Executive Officer’s employment by us for reasons not constituting Cause, including a resignation as a result of a change in his or her work location by more than a specified distance.
►	Change in Control Termination: includes a termination of the Named Executive Officer’s employment by us without Cause, or the resignation of the Named Executive Officer for Good Reason, within the applicable change in control protection period following a change in control of Gilead (i.e., “double trigger”).

For purposes of determining a Named Executive Officer’s eligibility for the various severance payments and benefits available under the Severance Plan, individual offer letters, and our equity plan, the following definitions are relevant:

A “change in control of Gilead” will be deemed to occur upon:

►	a merger, consolidation or other reorganization approved by our stockholders, unless our stockholders continue to own more than 50% of the total combined voting power of the voting securities of the successor corporation;
►	a sale of all or substantially all our assets; or
►	the acquisition by any person or related group of persons of more than 50% of the total combined voting power of our outstanding securities, or a change in the majority of the members of our Board over a 12-month or shorter period by reason of one or more contested elections for Board membership.

Under the Severance Plan and our equity plan, a “resignation for Good Reason” is defined as “Constructive Termination” and generally will be deemed to occur should a Named Executive Officer resign from his or her employment with us for any of the following reasons during the applicable change in control protection period:

►	an adverse change in his or her title, position or responsibilities (including reporting responsibilities) or the assignment to him or her of any duties or responsibilities which are inconsistent with his or her title, position or responsibilities;
►	a reduction in his or her annual base compensation;
►	his or her permanent relocation to any place outside a 50-mile radius of the location serving as his or her existing principal work site;
►	the failure by the new company to continue in effect any material compensation or employee benefit plan in which he or she was participating or to provide him or her with an aggregate level of compensation and benefits comparable to that in effect for him or her prior to the change; or
►	any material breach by the new company of any provision of any agreement we have with the Named Executive Officer.

In addition, a resignation following a required relocation, without consent, to a new work location that is more than 50 miles from his or her previous work location is also a good reason trigger under our severance plan outside the context of a change in control.

Mr. O’Day, Ms. Mercier and Dr. Parsey also have definitions of “Good Reason” under their individual offer letters with us, which generally allow for a “Good Reason” resignation, after a notice and cure period, upon:

►	an adverse change in employment status, title, position or responsibilities (including reporting responsibilities);
►	a reduction in annual base compensation or, for Ms. Mercier and Dr. Parsey, any reduction in target incentive or annual equity award opportunity prior to the first anniversary of the executive’s start date;
►	a required relocation to any place outside a specified radius of the greater Foster City, California area; or
►	for Mr. O’Day, a material breach by the Company or any subsidiary of the terms of his offer letter or of any written equity award agreement between him and the Company.

Executive Compensation

A Named Executive Officer’s employment will be deemed to have been terminated for “Cause” if such termination occurs by reason of:

►	any act or omission in bad faith and to our detriment;
►	dishonesty, intentional misconduct, material violation of any company policy, or material breach of any agreement with us;
►	commission of any crime involving dishonesty, breach of trust or physical or emotional harm to any person; or
►	poor performance, nonperformance, or neglect duties owed to us or insubordination.

The following table summarizes the payments and benefits that each currently employed Named Executive Officer is eligible to receive on various termination of employment scenarios.

Type of Termination
Voluntary or “For Cause” Termination		►No severance payments. ►Accrued base salary and vacation pay. ►Vested but unpaid benefits.
Retirement(1)		►To the extent retirement occurs at least 12 months after grant date, continued vesting of and five-year post retirement exercise period for stock options granted in or after 2019. Three-year post retirement exercise period for vested stock options granted in or prior to 2018. ►Continued vesting of 100% of performance shares for which performance goals are attained after retirement granted in or after 2019, provided retirement occurs at least 12 months after grant date. Pro-rata vesting of any performance shares granted prior to 2019 for which performance goals are attained after retirement. ►Continued vesting of 100% restricted stock units granted in or after 2019 in accordance with the standard vesting schedule, provided retirement occurs at least 12 months after grant date.
Type of Termination
Involuntary Termination without “Cause” or for “Good Reason”		►Cash severance equal to 1.5 times (2.0 times for Mr. O’Day) base salary + 1.0 times (2.0 times for Mr. O’Day) average cash incentive for prior three fiscal years (or such fewer number of complete fiscal years of employment). ►Pro-rata annual cash incentive for year of termination based on actual results attained. ►Lump-sum payment to cover the estimated cost of COBRA premiums for 18 months (or 24 months for Mr. O’Day). ►Outplacement services for 6 months (12 months for Mr. O’Day). ►For Mr. O’Day, crediting of $3,000,000 in unpaid deferred compensation plan company contribution to his plan account(2). ►For Mr. O’Day, accelerated vesting of make whole equity awards and 2019 grants of stock options, time-based restricted stock units, and performance shares (based on actual performance for completed performance periods and target for any uncompleted performance periods)(2). ►For Ms. Mercier and Dr. Parsey, if termination occurs within the first two years of employment, accelerated vesting of make whole equity awards.

Executive Compensation

Type of Termination Cont.
Change in Control Termination (Involuntary Termination without “Cause” or Resignation for “Good Reason” within Change in Control Protection Period(3))		►Cash severance equal to 2.5 times (3.0 times for Mr. O’Day) base salary + 2.5 times (3.0 times for Mr. O’Day) average incentive for prior three fiscal years (or such fewer number of complete fiscal years of employment). ►Pro-rata annual incentive for year of termination based on average incentive paid over the prior three years (or such fewer number of complete fiscal years of employment). ►Lump-sum payment to cover the estimated cost of COBRA premiums for 30 months (36 months for Mr. O’Day). ►Outplacement services for 6 months (12 months for Mr. O’Day). ►For Mr. O’Day, crediting of $3,000,000 in unpaid deferred compensation plan company contribution to his plan account. ►100% acceleration of stock option and restricted stock unit awards. ►Acceleration of unvested performance shares as follows: ►accelerates at target if change in control occurs within first 12 months of performance period. ►If the change in control occurs following that 12-month period, then accelerates at greater of (i) target or (ii) actual performance through the end of the fiscal quarter prior to the change in control date.

(1)	For equity awards granted in 2018 and prior years, retirement is defined as the termination of a Named Executive Officer’s employment with a combined age and years of service of not less than 70 years. For awards granted in 2019 and 2020, retirement is defined as termination of employment after the Named Executive Officer (i) attains age 55 and has completed at least ten (10) years of continuous service or (ii) attains age 65. As of December 31, 2020, no Named Executive Officers were retirement eligible.
(2)	Mr. O’Day is also entitled to these benefits upon termination because of death or disability.
(3)	The change in control protection period would begin six months prior to the consummation or a change in control transaction and continue for a specified period following the effective date of the change in control transaction (24 months for Mr. O’Day and 18 months for the other Named Executive Officers).

A Named Executive Officer must deliver a general release of claims against Gilead as a condition of his or her receipt of payments and benefits under his or her offer letter or the Severance Plan. The cash severance component of those arrangements will be paid in a series of equal periodic installments in accordance with our normal payroll practices over a period of years corresponding to the applicable multiple of base salary indicated above for the Named Executive Officer. However, a portion of those installments may be subject to a six-month holdback to the extent required under applicable tax laws.

The estimated severance payments and benefits for which a Named Executive Officer would have become eligible if his or her employment terminated under these various scenarios are set forth in the table below. The estimated amounts assume:

►	that the covered termination of employment occurred on December 31, 2020; and
►	the value of any equity vesting is based on the closing market price of our common stock on December 31, 2020.

The table below does not include accrued wages, vacation pay, vested deferred compensation or the intrinsic value (as of December 31, 2020) of any outstanding stock options or other stock awards held by the Named Executive Officer that were vested on that date. Due to the number of different factors that affect the nature and amount of any benefits provided in connection with these events, actual amounts payable to any of the Named Executive Officers should a separation from service or change in control occur during the year will likely differ, perhaps significantly, from the amounts reported below. Factors that could affect such amounts include the timing during the year of the event, our stock price, target amounts payable under annual and long-term incentive arrangements that are in place at the time of the event, and the executive’s age and prevailing tax rates.

(1)	Includes amounts earned but deferred for income tax purpose at the election of the NEOs pursuant to our 401(k) plan and our non-qualified deferred compensation plan.
(2)	Represents the aggregate grant-date fair value of the equity-based awards, including restricted stock units (RSUs), performance shares, performance-based RSUs and stock options granted to the NEOs for the applicable year under our 2004 Plan, calculated in accordance with FASB ASC Topic 718 (“Topic 718”), and does not take into account estimated forfeitures. Assumptions used in the calculation of such grant-date fair values are set forth in Note 16 to our Consolidated Financial Statements for the year ended December 31, 2020, included in our Annual Report on Form 10-K for such fiscal year. See the 2020 Grants of Plan-Based Awards table on pages 69-71 for additional information.
(3)	For 2020, represents amounts paid in early 2021 based on our Compensation & Talent Committee’s review and certification of corporate performance for Mr. O’Day and certification of corporate performance and individual achievements for all other NEOs in 2020 under our annual bonus plan.
(4)	Represents the aggregate grant-date fair value of the performance shares determined in accordance with Topic 718. The aggregate grant-date fair values of the awards reported for 2020 (the Relative TSR tranche of the 2020 performance shares and the 2020 revenue subtranches of the 2018, 2019 and 2020 performance shares, as applicable), assuming maximum attainment of the applicable performance goals in effect for those tranches and subtranches, are as follows: $7,400,615 for Mr. O’Day, $1,896,138 for Mr. Dickinson, $1,458,771 for Ms. Mercier, $1,666,392 for Dr. Parsey, and $2,173,629 for Mr. Pletcher. As described in the Compensation Discussion and Analysis, the revenue subtranches of the 2019 and 2020 performance shares for which performance objectives have not yet been set do not at present have a reportable grant-date fair value under Topic 718. The grant-date fair values assume maximum goal attainment only as to those tranches or subtranches that at present have a reportable grant-date fair value. Assumptions used in the calculation of such grant-date fair values are set forth in Note 16 to our Consolidated Financial Statements for the year ended December 31, 2020, included in our Annual Report on Form 10-K for such fiscal year.
	Performance objectives have been set for only certain tranches of the awards granted in each year and the associated grant-date fair values of those tranches have been incorporated in the table above. Tranches for which performance objectives have not been set do not have a reportable grant-date fair value under Topic 718 and therefore, are not included in the table above. Accordingly, amounts reported for 2020 reflect the grant-date fair value of awards granted in 2020 that are subject to a three-year Relative TSR performance condition and the portions of the 2018, 2019 and 2020 awards that are subject to the 2020 revenue goal.
	See footnotes 5, 6 and 9 to the 2020 Grants of Plan-Based Awards table on pages 69-71 for a detailed description of the terms of the 2020 performance shares.
(5)	Includes matching contributions of $15,000 made by us on such individual’s behalf under our 401(k) plan.
(6)	This “All Other Compensation” column amount includes $750,000 in company contributions to Mr. O’Day’s deferred compensation plan account, which was credited on March 1, 2020. Generally subject to his continued employment, Mr. O’ Day’s deferred compensation plan account will be credited with $750,000 on each of the next four anniversaries of March 1, 2020, for an aggregate contribution of $3,750,000. These contributions were provided to compensate him for the forfeiture of his pension benefits with his former employer. This amount also includes (i) $279,131 of relocation subsidy reimbursement, which includes tax reimbursements of $174,993, and (ii) $24,592, which reflects the aggregate incremental cost incurred by Gilead for Mr. O’Day’s personal use of our corporate aircraft, which is calculated based on variable operating costs including fuel, landing fees, parking costs, crew travel expenses, on-board catering, and other trip-related maintenance costs. Because our aircraft are used primarily for business travel, this amount does not include any fixed costs that do not change based on usage, such as pilots’ salaries or general maintenance costs.

(7)	Mr. O’Day’s 2019 pay also included one-time make-whole payments, which parallel the form and timing of payments Mr. O’Day forfeited at his former employer of 30 years and offset other economic consequences of accepting employment with us.
(8)	This “Bonus” column amount includes (i) the remaining $1,250,000 installment of Ms. Mercier’s sign-on bonus, which was paid on the first anniversary of her start date and intended to offset the value of the annual bonus and unvested equity awards forfeited from her prior employer and to compensate her for other economic consequences of accepting our offer; and (ii) a one-time $350,000 cash payment to help cover the costs of extending Ms. Mercier’s temporary housing, which full gross payment is subject to repayment in the event of Ms. Mercier’s termination for cause or resignation without good reason on or prior to June 19, 2021. The first fifty percent of her sign-on bonus was paid in 2019. This “All Other Compensation” column amount includes $205,243 of relocation subsidy, which includes tax reimbursements of $106,008. The relocation subsidy is repayable if Ms. Mercier’s employment terminates within two years of her start date.
(9)	This “Bonus” column amount reflects the remaining $1,000,000 installment of Dr. Parsey’s sign-on bonus, which was paid on the first anniversary of his start date and was intended to offset the value of his annual bonus and unvested equity awards forfeited from his prior employer. The first fifty percent of his sign-on bonus was paid in 2019.

Executive Compensation

(1)	Actual amounts paid in early 2021 were based on our Compensation & Talent Committee’s review and certification of corporate performance and individual achievements in 2020 under our annual incentive program and are included in the “Non-Equity Incentive Plan Compensation” column of the Summary Compensation Table on pages 67-68.
(2)	Performance shares and RSU awards (both time-based and performance-based) granted under the 2004 Plan accrue forfeitable dividend equivalents that are subject to the same vesting and other terms and conditions as the corresponding performance shares and RSU awards. Dividend equivalents are accumulated and paid in cash when and to the extent the underlying shares are issued. Amounts in the “Threshold” column represent the number of shares of our common stock issuable (e.g., 20% of the target number of performance shares allotted to the revenue subtranche and 0.025% of the target number of performance shares allotted to the Total Shareholder Return (Relative TSR) tranche) upon threshold-level achievement of the performance goals described in footnotes 5, 6 and 9 below. If threshold level performance is not achieved, no shares are issuable.
(3)	Represents the grant-date fair value of each equity award, calculated in accordance with Topic 718, and does not take into account estimated forfeitures. The grant-date fair value of the performance shares awarded is based on the probable outcome at 100% target level attainment of one or more pre-established performance objectives and the assumptions used in the calculation of the grant-date fair value of options are set forth in Note 16 to our Consolidated Financial Statements for the year ended December 31, 2020, included in our Annual Report on Form 10-K for such fiscal year.
(4)	Performance objectives were set for certain tranches of performance shares which were approved in prior years by our Compensation & Talent Committee and the associated grant-date fair value of those tranches has been incorporated in the table above (i.e., the performance objectives for the third subtranche of the 2018 revenue-based performance shares, for Mr. Dickinson and Mr. Pletcher, and the second subtranche of the 2019 revenue-based performance shares for Mr. O’Day, Mr. Dickinson and Mr. Pletcher). Performance shares that had no grant date as the performance objectives had not yet been defined as of the close of the 2020 fiscal year, and therefore, do not have a reportable 2020 grant-date fair value under Topic 718 are excluded from the Summary Compensation Table and the table above (i.e., the performance objectives for the third subtranche of the 2019 revenue-based performance shares and the second and third subtranches of the 2020 revenue-based performance shares).
	Because of changes in our stock price between the date of the approval by our Compensation & Talent Committee and the time when the performance objectives are established, the reported grant-date fair value of the performance shares differs from the award value approved by our Compensation & Talent Committee. As a result, only approximately two-thirds of the value of performance shares awarded in 2020 is included in the Summary Compensation Table and the table above. The value of the relevant performance shares awarded to our NEOs is as set forth below:

(5)	Represents the grant-date fair value of the 2020 revenue subtranche of performance shares awarded in 2019 under the 2004 Plan, as that value was measured on March 10, 2020, the date on which the revenue target for that particular subtranche was first communicated to the NEOs (following approval by our Compensation & Talent Committee). Although such subtranche was part of the performance share awards originally made on February 6, 2019 and March 1, 2019, no grant-date fair value could be determined for that subtranche under Topic 718 until March 10, 2020.
	The 2019 performance shares were divided into two equally-weighted Relative TSR and revenue tranches based on award value approved by the Compensation & Talent Committee similar to the description of the 2020 performance shares in footnote 6 below. Based on the terms of the awards, any shares accrued on the basis of the applicable level of Relative TSR goal attainment are also subject to a service-vesting condition that generally requires continued service with us through the date following the completion of the performance period on which our Compensation & Talent Committee certifies the Relative TSR level attained (the “Relative TSR-based Awards Certification Date”). The Relative TSR three-year performance period is from February 1, 2019 through December 31, 2021. Based on the terms of the awards, any shares accrued on the basis of the applicable level of revenue goal attainment are also subject to a service-vesting condition that requires continued service with us through the date following the completion of the third subtranche performance period on which our Compensation & Talent Committee certifies the attained level of the consolidated net product revenue goal applicable to the third subtranche (the “Revenue-based Awards Certification Date”), subject to pro-rata vesting in the event of death, disability or retirement before that date.
	Since the revenue goal for the third subtranche of the 2019 performance share award had not been set by our Compensation & Talent Committee as of the close of the 2020 fiscal year, that subtranche does not have a determinable grant-date fair value under Topic 718 for the 2020 fiscal year.
(6)	Represents the grant-date fair value of the 2020 performance shares awarded on March 10, 2020.
	The 2020 performance shares were divided into two equally-weighted Relative TSR and revenue tranches based on award value approved by the Compensation & Talent Committee. The performance-based vesting requirement for the Relative TSR tranche was set by our Compensation & Talent Committee on January 29, 2020 and is tied to the percentile level of our Relative TSR for the three-year performance period from March 1, 2020 through December 31, 2022 relative to the Relative TSR realized for that same period by the companies comprising three subsets of the S&P Health Sub-Index. Based on the terms of the awards, to receive any shares of our common stock accrued pursuant to this Relative TSR tranche, an executive officer must remain employed with us through the Relative TSR-based Awards Certification Date, subject to pro-rata vesting in the event of death, disability or retirement before that date.

Executive Compensation

	The performance-based vesting requirement for the revenue tranche of each performance award is divided into three equal subtranches, each with its own one-year performance period and applicable service period of one or more specified years, as follows:
	The performance-based vesting requirement for the first subtranche was the achievement of the target level of consolidated net product revenue for the 2020 fiscal year as set by our Compensation & Talent Committee. The grant-date fair value of that particular subtranche was measured on March 10, 2020, in accordance with Topic 718. Based on the terms of the awards, any shares accrued on the basis of revenue goal attainment for this subtranche are also subject to a service-vesting condition that requires continued service through the Revenue-based Awards Certification Date.
	Since the revenue goals for the second and third subtranches of the revenue tranche of the 2020 performance shares had not been set by our Compensation & Talent Committee as of the close of the 2020 fiscal year, those subtranches do not have a determinable grant-date fair value under Topic 718 for the 2020 fiscal year.
(7)	Reflects option awards granted under our 2004 Plan, the terms of which are consistent with those of options granted to other employees under the 2004 Plan. The options vest at the rate of 25% on the first anniversary of the grant date and 6.25% each quarter thereafter during the optionee’s employment over the next 36 months. Subject to earlier forfeiture, the maximum term of options granted under the 2004 Plan is 10 years. The exercise price per share of each option granted was equal to the closing market price of our common stock on the grant date or the closing market price on the day before the grant date if the grant date is not on a business day.
(8)	Represents time-based RSU awards under the 2004 Plan that vest in a series of four successive annual installments upon completion of each year of continued service over the four-year period measured from the grant date.
(9)	Represents the grant-date fair value of the 2020 revenue subtranche of performance shares awarded in 2018 under our 2004 Plan, as that value was measured on March 10, 2020, the date on which the revenue target for that particular subtranche was first communicated to the NEOs (following approval by our Compensation & Talent Committee). Although such subtranche was part of the performance share award originally made on February 1, 2018, no grant-date fair value could be determined for that subtranche under Topic 718 until March 10, 2020.
	The 2018 performance shares were divided into two equally-weighted Relative TSR and revenue tranches based on award value approved by the Compensation & Talent Committee similar to the description of the 2020 performance shares in footnote 5 above. Based on the terms of the awards, any shares accrued on the basis of the applicable level of Relative TSR and revenue goal attainment are also subject to a service-vesting condition that requires continued service with us through the awards certification date, subject to pro-rata vesting in the event of death, disability or retirement before that date.

(1)	The options granted under the 2004 Plan vest over a four-year period at the rate of 25% on the first anniversary of the grant date and 6.25% each quarter thereafter during the optionee’s employment. Each option is exercisable over a period not to exceed the contractual term of ten years from the grant date.

Executive Compensation

(2)

Amount reflects the pro-rated amount of the bonus payable for the year of termination based on 2020 actual performance pursuant to the Severance Plan (as amended and restated May 5, 2020) in the event of a termination outside the context of a change in control, and a pro-rated annual incentive for year of termination based on the average bonus paid over the prior three years (or such fewer number of complete fiscal years of employment) in the context of a termination within the change in control protection period.

(3)

Amount reflects $58.26 (our closing stock price on December 31, 2020) multiplied by the number of shares covered by each accelerating award. All unvested options that would accelerate were out-of-the money on December 31, 2020, and thus are not reflected. 2018 performance awards tied to Relative TSR reflect payout at 0% of target. 2018 performance awards tied to revenue reflect payout at 163.4% of target (163.4% for first subtranche, 126.7% for second subtranche, 200% for third subtranche). 2019 performance awards tied to Relative TSR assume payout at 100% of target. 2019 performance awards tied to revenue assume only first subtranche and second subtranche are outstanding at time of change of control (per award agreement terms) with payout at 126.7% of target for first subtranche and 200% of target for second subtranche. 2020 performance awards tied to Relative TSR assume payout at 100% of target. 2020 performance awards tied to revenue assume only first subtranche are outstanding at time of change of control (per award agreement terms) with payout at 200% of target.

CEO Pay Ratio

We present below the ratio of annual total compensation of our median compensated employee to the annualized total compensation of Mr. O’Day.

The ratio presented below is a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K. The SEC’s rules for identifying the median compensated employee and calculating the pay ratio based on that employee’s annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions and to make reasonable estimates and assumptions that reflect their employee populations and compensation practices. As a result, the pay ratio reported by other companies may not be comparable to the pay ratio reported below, as other companies have different employee populations and compensation practices and may utilize different methodologies, exclusions, estimates and assumptions in calculating their own pay ratios.

For 2020, we used the same median employee identified for purposes of calculating our 2019 pay ratio because we believe there has been no change in our employee population or employee compensation arrangements that would significantly impact the pay ratio disclosure. In identifying such median paid employee, we applied the following steps:

►	We identified our median compensated employee from the 11,486 full-time and part-time workers who were included as employees on our payroll records as of October 1, 2019 based on year-to-date base salary, incentive, commissions and equity, with conforming adjustments for employees who were hired during that period but did not work the full nine months.
►	We then excluded employees at the median who had anomalous compensation characteristics to determine the median compensated employee.

The 2020 total compensation for Mr. O’Day was $18,998,905. The 2020 annual total compensation as determined under Item 402 of Regulation S-K for our median employee was $250,190. The ratio of Mr. O’Day’s total compensation to our median employee’s total annual compensation for fiscal year 2020 is 76 to 1.

	Proposal 4

	Stockholder Proposal Requesting that the Board Adopt a Policy that the Chairperson of the Board of Directors be an Independent Director United Church Funds and co-filers have submitted a stockholder proposal for consideration at the Annual Meeting. United Church Funds’ address is 475 Riverside Drive, Suite 1020, New York, NY 10115. We have been notified that United Church Funds has continuously held shares our common stock worth at least $2,000 since at least October 23, 2019. We will provide the name, address and known share holdings of the co-filers of this proposal upon written or oral request to the Corporate Secretary at the address set forth in question 17 in “Questions and Answers.” If properly presented at the Annual Meeting, our Board unanimously recommends a vote “AGAINST” the following proposal. The resolution being submitted by United Church Funds and co-filers to the stockholders for approval is as follows: Stockholder Proposal RESOLVED: Gilead Sciences (“Gilead” or the “Company”) shareholders request the Board of Directors adopt as policy (the “Policy”), and amend the bylaws as necessary, to require henceforth that the Chair of the Board of Directors, whenever possible, be an independent member of the board. The Policy shall apply prospectively so as not to violate any contractual obligations. If the board determines that a Chair who was independent when selected is no longer independent, the board shall select a new Chair who satisfies the requirements of the policy within a reasonable amount of time. Compliance with this policy is waived if no independent director is available and willing to serve as Chair. Supporting Statement We believe our board of directors should be chaired by an independent director. A chair is better positioned to represent shareholder interests when the role is held by a director that is independent of corporate management. The Company’s recent performance relative to peers as well as controversies involving the pricing of its products makes this an opportune time to adopt a policy requiring an independent director serve as board chair. At our Company, the CEO Daniel O’Day also serves as Chairman of the Board. Shareholders manifested opposition to Gilead’s executive pay at the 2020 annual general meeting, where 16.3% voted against the advisory vote on executive compensation. Proxy advisor ISS found a misalignment in pay for performance with Gilead underperforming its peer group on a one, three and five year basis while compensating its CEO well above the peer median. On September 23, 2020, the Department of Justice reported that Gilead agreed to pay $97 million to resolve allegations that it violated the False Claims Act by paying kickbacks. Eleven State Treasurers have questioned Gilead on price gouging on its Remdesivir anti-viral during a global pandemic. The current Lead Independent Director, Kevin Lofton, is not a sufficient substitute for an independent Chair. Mr. Lofton appears overstretched with directorships at two other Fortune 500 companies (Rite Aid and Medtronic) and several non-profit boards. We also question Mr. Lofton’s independence after serving on the board for over 11 years. An independent chair is a fundamental corporate governance best practice and is preferred by many investors. ISS reported in September 2020 that 85 percent of investors responding to its policy survey indicated that an independent chair is their preferred model. Thirty-four percent of S&P 500 boards have an independent chair, according to a 2019 Spencer Stuart report, up from 31 percent the previous year. The Council of Institutional Investors’ corporate governance policies favor independent board chairs. A similar proposal filed with Gilead last year saw significant support with a vote in favor of 43.39%. In order to ensure that our Board can provide rigorous oversight for our Company with greater independence and accountability, we urge a vote FOR this shareholder proposal.

Stockholder Proposal

Our Board Recommends a Vote AGAINST This Proposal

Board’s View Aligns with Recent Stockholder Votes on This Issue

In 2013-2015 and 2017-2020, our Board carefully considered stockholder proposals requesting that our Board adopt a policy that the Chairperson of the Board be an independent director. In each of those votes, the majority of shares were voted AGAINST the proposals. Our Board continues to believe that stockholder interests are best served when the Board has the flexibility to determine the best person to serve as Chairperson, and that the robust duties of our Lead Independent Director provide strong independent Board leadership. Our Board recommends a vote AGAINST this proposal.

The Board Should Have Flexibility to Structure an Appropriate Governance Structure Tailored to the Needs of Gilead

One of the most important tasks undertaken by a board is to select the leadership of the board and the company. In order to execute this critical function most effectively and in the best interest of our stockholders, our Board has the flexibility to design Gilead’s board leadership structure as our Board deems appropriate based on the circumstances at the time. Our Board is composed of directors with diverse backgrounds, experiences and perspectives, as well as extensive knowledge about Gilead’s business and our industry, and is best positioned to evaluate the optimal Board leadership structure.

Our current policy enables our Board to choose a leadership structure that can be tailored to the strengths of Gilead’s officers and directors and best addresses Gilead’s evolving and highly complex business. The policy also allows our Board to make changes in the company’s leadership structure when the Board believes that such actions are in the best interests of the company and its stockholders. Departing from Gilead’s current policy would unduly impair our Board’s ability to select the director it believes is best suited to serve as Chairperson based on the circumstances at the time.

The independent directors review this structure on a regular basis to ensure that it continues to serve the best interests of Gilead. As part of this review, the Board incorporates feedback from investors gained through our year-round stockholder engagement efforts. In addition, our annual Board self-assessment process evaluates the effectiveness of the Board, the Chairperson’s leadership of the Board and our Lead Independent Director. Our Board has determined that it is currently in the best interests of Gilead to partner a powerful Lead Independent Director with our Chairperson of the Board.

In May 2020, our Board unanimously appointed Kevin Lofton as our new Lead Independent Director, in recognition of his leadership experience, in-depth knowledge of Gilead and demonstrated commitment to the role. Having served as a director on the Board since 2009, he has developed deep knowledge of our operations and business cycles, including serving on the Board through development of our HCV business. Mr. Lofton also has significant leadership experience on other public boards and in the healthcare industry, including experience serving as a Chief Executive Officer and a board member of several large organizations. He has demonstrated his commitment to improving access to medical service, particularly for the underserved. Given his proven leadership capability, breadth of industry experience and business success, our Board believes Mr. Lofton is a strong and effective partner to our Chairperson of the Board.

Currently, Having Mr. O’Day as Our Chairman of the Board Is in the Best Interests of Gilead and Its Stockholders

The independent Directors of the Board have concluded that it is currently in the best interests of Gilead and its stockholders for Mr. O’Day to serve as our Chief Executive Officer and Chairman of the Board because it best positions Mr. O’Day to effectively drive future strategy and decision-making for our organization.

In addition to Mr. O’Day’s public, private and non-profit board experience, he has a track record of success in highly scientific and competitive therapeutic areas, deep understanding of the evolving healthcare environment around the world and unwavering commitment to driving innovation across all aspects of a business.

Stockholder Proposal

Our Lead Independent Director Ensures Our Board’s Independent Leadership and Accountability

We believe the robust duties of our Lead Independent Director empower our independent directors to provide effective guidance and oversight of management. The role of Lead Independent Director at Gilead is modeled on the role of an independent Chairperson, ensuring a strong, independent and active Board of Directors. As set forth in the Lead Independent Charter adopted by our Board, the Lead Independent Director has clearly delineated and comprehensive duties. These duties include:

►	Consulting with the Chairperson as to an appropriate schedule of Board meetings, seeking to ensure that the independent directors can perform their duties responsibly while not interfering with ongoing company operations;
►	Consulting with the Chairperson regarding and approving the information, agenda and schedules of meetings of the Board of Directors and Board committees;
►	Advising the Chairperson as to the information necessary or appropriate for the independent directors to effectively and responsibly perform their duties and provide feedback on the quality, quantity and timeliness of information submitted by management;
►	Advising the Board of Directors and its committees on the retention of advisers and consultants who report directly to the Board of Directors;
►	Calling meetings of the independent directors, as appropriate;
►	Chairing meetings of the Board of Directors when the Chairperson is not present or when otherwise appropriate, including all executive sessions of independent directors;
►	Serving as principal liaison between the independent directors and the Chairperson and between the independent directors and senior management;
►	Providing independent directors with adequate opportunities to meet and discuss issues in meetings of the independent directors;
►	Encouraging director participation by fostering an environment of open dialogue and constructive feedback among independent directors;
►	Communicating to management, as appropriate, the results of private discussions among independent directors;
►	Facilitating the effective functioning of key Board committees and providing input on functioning of the committees, when required;
►	Participating on ad-hoc committees established to deal with extraordinary matters, such as investigations and mergers and acquisitions;
►	Providing guidance on director succession and development;
►	Ensuring Board agendas provide the Board with the ability to periodically review and provide input on the company’s long-term strategy and to monitor management’s execution of the long term-strategy;
►	Unless otherwise directed by the Board, serving as the independent directors’ representative in crisis situations;
►	Monitoring, in collaboration with the Nominating and Corporate Governance Committee, conflicts of interest of all directors, including the Chief Executive Officer;
►	Participating, in collaboration with the Compensation and Talent Committee, in succession planning for the Chief Executive Officer and in talent retention and development programs for members of senior management;
►	Responding, as appropriate, to stockholder and other stakeholder questions and comments that are directed to the Lead Independent Director or to the independent directors as a group, with such consultation with the Chairperson and other directors as the Lead Independent Director may deem appropriate;
►	Representing independent directors in communications with other stakeholders, as required; and
►	Performing such other duties as the Board of Directors may from time to time delegate.

In addition, as required by our Board Guidelines, Gilead’s independent directors meet without executive management on a routine basis to review, among other things, Gilead’s strategy, performance, management effectiveness and succession planning.

Our Corporate Governance Practices Empower Our Independent Directors to Select the Right Leadership Structure as Gilead Navigates Changing Conditions

Gilead’s strong corporate governance policies and practices provide our independent directors with the ability to effectively oversee our management and make well-informed decisions about critical issues, such as the Board’s leadership structure.

►	Substantial majority of our directors are independent. Currently, eight out of the nine director nominees are independent.
►	Fully independent Board committees. All members of the key Board committees—the Audit Committee, the Compensation and Talent Committee and the Nominating and Corporate Governance Committee—are “independent” in accordance with or as defined in the rules adopted by the SEC and Nasdaq and Gilead’s own Board Guidelines. This ensures that oversight of critical matters such as the integrity of our financial statements, the compensation of our executive officers, the selection and evaluation of directors and the development of corporate governance principles is entrusted to independent directors.
►	Annual Board and committee evaluations. Our Lead Independent Director conducts an annual assessment of the Board, the Chairperson’s Board leadership and committees of the Board to evaluate their effectiveness.
►	Independent evaluation of Chief Executive Officer performance. Our Compensation and Talent Committee, which is fully independent, is responsible for performing an annual evaluation of the Chief Executive Officer against his performance objectives.
►	Ongoing Board refreshment. Our Nominating and Corporate Governance Committee regularly evaluates the Board’s composition to ensure a diversity of perspectives and skill-sets to oversee management’s execution of our strategy.
►	Ability to consult with external advisers. Our Lead Independent Director has the authority to engage outside advisers and consultants as he deems appropriate to fulfill his responsibilities.
►	Established corporate governance guidelines. We maintain strong corporate governance policies and practices. Information regarding our corporate governance initiatives, including our Board Guidelines and the charter for each Board committee, can be found on our website at www.gilead.com on the Investors page under “Corporate Governance.”

We believe that the interests of our stockholders will be best served by maintaining our Board’s flexibility in determining the board leadership structure that is best suited to the needs of Gilead at any particular time.

Householding of Proxy Materials

The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for Notices of Internet Availability of Proxy Materials or other Annual Meeting materials with respect to two or more stockholders sharing the same address by delivering a single Notice or other Annual Meeting materials addressed to those stockholders. This process, which is commonly referred to as householding, potentially provides extra convenience for stockholders and cost savings for companies.

This year, a number of brokers with account holders who are our stockholders will be “householding” our proxy materials. A Notice will be delivered in one single envelope to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker that they will be “householding” communications to your address, “householding” will continue until you are notified otherwise or until you revoke your consent. If you hold your shares through a broker and would prefer to receive a separate Notice, please notify your broker. If you hold your shares directly and would prefer to receive a separate Notice, please submit a written request to Gilead Sciences, Inc., Attention: Investor Relations, 333 Lakeside Drive, Foster City, California 94404 or contact Broadridge Financial Solutions, Inc. at (866) 540-7095. Stockholders who currently receive multiple copies of the Notice at their address and would like to request “householding” of their communications should contact their broker. In addition, we will promptly deliver, upon written or oral request to the address or telephone number above, a separate copy of the Notice to a stockholder at a shared address to which a single copy of the documents was delivered.

By Order of the Board of Directors,

Brett A. Pletcher
Corporate Secretary

March 30, 2021

A copy of our Annual Report on Form 10-K for the year ended December 31, 2020 is available without charge upon written request to Investor Relations, Gilead Sciences, Inc., 333 Lakeside Drive, Foster City, California 94404 or by accessing a copy through Gilead’s website at www.gilead.com on the Investors page under “SEC Filings.”

1. Why did I receive a notice regarding the availability of proxy materials on the Internet?

Pursuant to rules adopted by the SEC, we have elected to provide access to our proxy materials primarily over the Internet. Accordingly, we are sending a Notice of Internet Availability of Proxy Materials (the “Notice”) to our stockholders of record. This approach conserves natural resources and reduces our costs of printing and distributing our proxy materials, while providing stockholders with a convenient way to access our proxy materials. All stockholders will have the ability to access the proxy materials on the website referred to in the Notice or to request a printed set of the proxy materials, including a proxy card. Instructions on how to access the proxy materials over the Internet or to request a printed copy may be found in the Notice.

2. How may I obtain a copy of Gilead’s Annual Report on Form 10-K and other financial information?

A copy of our 2020 Annual Report, which includes our Form 10-K for the year ended December 31, 2020, is available at investors.gilead.com/annual-meeting or may be requested from our Investor Relations department as described elsewhere in this Proxy Statement. Our 2020 Annual Report is not incorporated into this Proxy Statement and should not be considered proxy solicitation material.

3. Who is entitled to vote at the Annual Meeting?

Only holders of our common stock at the close of business on March 19, 2021 are entitled to receive the Notice and to vote their shares at the Annual Meeting. As of that date, there were 1,259,056,043 shares of common stock outstanding and entitled to vote. Each share of common stock is entitled to one vote on each matter to be voted upon at the Annual Meeting.

Questions and Answers

6. What items of business will be voted on at the Annual Meeting?

The items of business scheduled to be voted on at the Annual Meeting are:

►	to elect the nine director nominees named in this Proxy Statement to serve for the next year and until their successors are elected and qualified;
►	to ratify the selection of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2021;
►	to approve, on an advisory basis, the compensation of our Named Executive Officers as presented in this Proxy Statement; and
►	to vote on a stockholder proposal, if properly presented at the meeting, requesting that the Board adopt a policy that the Chairperson of the Board of Directors be an independent director.

We also will consider any other business that properly comes before the Annual Meeting. See question 11, “Could other matters be decided at the Annual Meeting?” on page 87.

7. How does the Board recommend that I vote?

Our Board recommends that you vote your shares:

►	“FOR” each of the nine director nominees named in this Proxy Statement;
►	“FOR” the ratification of the selection of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2021;
►	“FOR” the approval, on an advisory basis, of the compensation of our Named Executive Officers as presented in this Proxy Statement; and
►	“AGAINST” the stockholder proposal requesting that the Board adopt a policy that the Chairperson of the Board of Directors be an independent director.

8. What are the voting requirements to elect the directors and to approve each of the proposals discussed in this Proxy Statement?

A quorum of stockholders is necessary to hold a valid meeting. A quorum will be present if a majority of the outstanding shares is represented by votes present at the meeting in person or by proxy. Shares represented by proxies marked “abstain” and “broker non-votes” are counted in determining whether a quorum is present.

Proposal		Vote Required
Proposal 1 – Election of the nine director nominees named in this Proxy Statement to serve for the next year and until their successors are elected and qualified.		Majority of votes cast (number of shares voted “for” a director must exceed the number of shares voted “against” that director).
Proposal 2 – Ratification of the selection of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2021.		Majority of the shares entitled to vote on the proposal and present in person or represented by proxy.
Proposal 3 – Approval, on an advisory basis, of the compensation of our Named Executive Officers as presented in this Proxy Statement.		Majority of the shares entitled to vote on the proposal and present in person or represented by proxy.
Proposal 4 – Vote on a stockholder proposal, if properly presented at the meeting, requesting that the Board adopt a policy that the Chairperson of the Board of Directors be an independent director.		Majority of the shares entitled to vote on the proposal and present in person or represented by proxy.

If your shares are held by a broker and you do not indicate how you wish to vote, your broker is permitted to exercise its discretion to vote your shares only on certain “routine” matters. Proposal 2 is a “routine” matter. As a result, your broker is permitted to exercise discretionary voting authority to vote your shares for this proposal. Your broker may not exercise discretionary voting authority and may not vote your shares with respect to the other proposals unless you provide your broker with voting instructions. This is known as a “broker non-vote.”

Questions and Answers

With respect to Proposal 1, abstentions will have no effect on the outcome of the vote. With respect to Proposals 2, 3 and 4, abstentions will have the same effect as an “against” vote. “Broker non-votes” will have no effect on the outcome of the vote for Proposals 1-4.

9. How do I Vote?

You may vote by completing and returning a proxy by mail or voting your shares by Internet or telephone by 11:59 p.m., Eastern Daylight Time, on May 11, 2021. You may also vote by Internet during the Annual Meeting.

If your shares are registered directly in your name with Gilead’s transfer agent, Computershare, you are considered a “stockholder of record.” If your shares are held in a stock brokerage account or by a bank or other nominee, you are considered the beneficial owner of shares held in “street name.” Most beneficial owners whose stock is held in the name of a bank, broker or other nominee receive instructions for how to vote their shares from their banks, brokers or other nominees, rather than our proxy card. You can vote your shares held through a bank, broker or other nominee by following the voting instructions sent to you by that institution.

By mail before the Annual Meeting

To vote your proxy by mail, be sure to complete, sign and date the proxy card (if you request one) or voting instruction card that may be delivered to you and return it in the envelope provided. We will vote your shares as directed. However, if you return your signed proxy card but do not indicate your voting preferences, the persons named on the proxy card will vote the shares represented by that proxy as recommended by our Board.

By Internet or telephone before the Annual Meeting

Stockholders may vote their shares by Internet or telephone before the Annual Meeting. The law of the State of Delaware, under which we are incorporated, specifically permits electronically transmitted proxies so long as each such proxy contains or is submitted with information from which the inspector of election can determine that such proxy was authorized by the stockholder. The Internet and telephone voting procedures below are designed to authenticate stockholders’ identities to allow stockholders to vote their shares and to confirm that stockholders’ instructions have been recorded properly. Stockholders voting shares via the Internet should understand that there may be costs associated with electronic access, such as usage charges from Internet access providers and telephone companies, which must be borne by the stockholder.

Stockholders of record may go to www.proxyvote.com to vote their shares. You will be required to provide the control number printed on your Notice. The votes represented by such proxy will be generated on the computer screen and the voter will be prompted to submit or revise them as desired. Stockholders of record who requested paper copies of the proxy materials and are using a touch-tone telephone may vote their shares by calling (800) 690-6903 and following the recorded instructions.

A number of brokers and banks are participating in a program that offers the ability to vote shares over the telephone and Internet. Street name holders may vote on the Internet by accessing www.proxyvote.com. You will be required to provide the control number printed on your Notice. Street name holders who requested paper copies of the proxy materials and are using a touch-tone telephone may vote their shares by calling (800) 454-8683 and following the recorded instructions.

Internet and telephone voting for stockholders of record and street name holders will be available 24 hours a day, and will close at 11:59 p.m., Eastern Daylight Time, on May 11, 2021. Submitting your proxy via the Internet or by telephone will not affect your right to vote in person should you decide to attend the Annual Meeting.

By Internet during the Annual Meeting

Stockholders may vote their shares by Internet during the Annual Meeting. Please follow the instructions at www.virtualshareholdermeeting.com/GILD2021 to vote or submit questions during the meeting. You will be required to provide the control number printed on your Notice to enter the virtual meeting. The Internet voting procedures are designed to authenticate stockholders’ identities to allow stockholders to vote their shares and to confirm that stockholders’ instructions have been recorded properly.

Even if you plan to attend the Annual Meeting, we encourage you to vote your shares promptly by mail, Internet or telephone in advance of the Annual Meeting. A stockholder may still attend the meeting and vote during the meeting if he or she has already voted by one of these methods. Any vote submitted during the meeting would supersede any prior vote.

Your vote is important. You can save us the expense of a second mailing of proxy materials by voting promptly.

Questions and Answers

10. What can I do if I change my mind after I vote my shares?

Any stockholder giving a proxy pursuant to this solicitation has the power to revoke it at any time before the shares are voted.

If you are a stockholder of record, you can revoke your proxy before it is exercised by:

►	submitting a written notice to our Corporate Secretary at our principal executive offices, 333 Lakeside Drive, Foster City, California 94404;
►	submitting a valid, later-dated proxy or a later-dated vote by Internet or telephone by 11:59 p.m., Eastern Daylight Time, on May 11, 2021; or
►	voting during the Annual Meeting.

If you are a beneficial owner of shares, you may revoke your proxy or submit new voting instructions by contacting your bank, broker or other holder of record.

You may also vote during the Annual Meeting as described in the answer to the preceding question. Attendance at the meeting will not, by itself, revoke a proxy. All shares for which proxies have been properly submitted and not revoked will be voted at the Annual Meeting.

11. Could other matters be decided at the Annual Meeting?

On the date this Proxy Statement went to press, we did not know of any matters to be raised at the Annual Meeting other than those referred to in this Proxy Statement. If other matters are properly presented at the Annual Meeting for consideration and you execute and deliver a proxy, then Daniel P. O’Day and Brett A. Pletcher, the persons named on your proxy card, will have the discretion to vote on those matters for you.

12. Is my vote confidential?

Yes. Proxy cards and voting tabulations that identify stockholders by name are kept confidential. There are exceptions for contested proxy solicitations or when necessary to meet legal requirements. Veaco Group, the independent proxy tabulator that we have engaged, will count the votes and act as the inspector of election for the meeting.

13. How can I ask questions at the Annual Meeting?

The Annual Meeting will include a question and answer session to address questions submitted in writing in advance of and during the Annual Meeting that comply with our Rules of Conduct and Procedures and as time permits. Questions may be submitted within the 48-hour period preceding the start of the Annual Meeting at www.proxyvote.com or during the Annual Meeting at www. virtualshareholdermeeting.com/GILD2021. If you wish to submit a question during the Annual Meeting, log in to the virtual meeting website using the control number that appears on your Notice of Internet Availability of Proxy Materials, type your question into the “Ask a Question” field and click “Submit”. Questions and Answers may be grouped by topic and substantially similar questions may be grouped and answered once. You may view the Rules of Conduct and Procedures prior to the meeting at our Investors page at investors.gilead.com/annual-meeting or during the meeting at the Annual Meeting website.

14. Where can I find the voting results of the Annual Meeting?

We will announce preliminary voting results at the Annual Meeting and publish final results in a Current Report on Form 8-K within four business days after the Annual Meeting.

15. Who will pay for the cost of this proxy solicitation?

We will pay the cost of soliciting proxies, including preparation, assembly, printing and mailing of the Notice and this Proxy Statement and any additional information furnished to stockholders. Copies of solicitation materials will be furnished to banks, brokerage houses, fiduciaries and custodians holding in their names shares of our common stock beneficially owned by others to forward to such beneficial owners. We may reimburse persons representing beneficial owners of common stock for their out-of-pocket expenses for forwarding solicitation materials to such beneficial owners. We have hired Innisfree M&A Incorporated to act as our proxy solicitor in conjunction with the Annual Meeting. We will pay Innisfree M&A Incorporated a fee of $25,000, plus reasonable out-of-pocket expenses, for these services. Our solicitation of proxies by mail may be supplemented by telephone, facsimile, electronic mail or personal solicitation by directors, officers or other of our employees. No additional compensation will be paid to directors, officers or other employees for such solicitation services performed by them.
