Stockholders of record at the close of business on April 19, 2021, the record date for the Annual Meeting, are entitled to notice of, and to vote at, the Annual Meeting or any adjournment or postponement of the Annual Meeting.

You can find more information on each of the matters to be voted on at the Annual Meeting, including information regarding the nominees for election to our board of directors, in the accompanying proxy statement. The board of directors recommends a vote “FOR” the election of the three nominees for class I directors and “FOR” the ratification of the appointment of our independent registered public accounting firm for the fiscal year ending December 31, 2021, as disclosed in the accompanying proxy statement.

We are pleased to comply with the rules of the Securities and Exchange Commission that allow companies to distribute their proxy materials over the Internet under the “notice and access” approach. As a result, we are mailing to our stockholders a Notice of Internet Availability of Proxy Materials, or Notice of Availability, instead of a paper copy of our proxy materials and our Annual Report for the fiscal year ended December 31, 2020, or the 2020 Annual Report. We will mail the Notice of Availability on or about May 1, 2021, and it contains instructions on how to access those documents and to cast your vote over the Internet. This process allows us to provide our stockholders with the information they need on a more timely basis, while reducing the environmental impact and lowering the costs of printing and distributing our proxy materials. If you would like to receive a printed copy of our proxy materials, including our proxy statement, our 2020 Annual Report and a form of proxy card, free of charge, please follow the instructions on the Notice of Availability.

In order to attend the Annual Meeting virtually, you must register in advance at www.virtualshareholdermeeting.com/KYMR2021 prior to the deadline of June 14, 2021 at 5:00 p.m. Eastern

Time. You will be required to enter the control number provided in the Notice of Availability or the proxy card at www.virtualshareholdermeeting.com/KYMR2021 and beneficial owners of shares held in street name will need to register as well, and additionally must follow the instructions provided in the voting instructions form by the broker, bank or other nominee that holds their shares.

In addition, as an emerging growth company, we are not required to conduct votes seeking approval, on an advisory basis, of the compensation of our named executive officers or the frequency with which such votes must be conducted. We will remain an “emerging growth company” until the earliest of (i) the last day of the fiscal year following the

1

fifth anniversary of our initial public offering in August 2020; (ii) the last day of the fiscal year in which our total annual gross revenue is equal to or more than $1.07 billion; (iii) the date on which we have issued more than $1 billion in nonconvertible debt during the previous three years; or (iv) the date on which we are deemed to be a large accelerated filer under the rules of the Securities and Exchange Commission, or the SEC. Even after we are no longer an “emerging growth company,” we may remain a “smaller reporting company.”

KYMERA THERAPEUTICS, INC

PROXY STATEMENT

FOR THE 2021 ANNUAL MEETING OF STOCKHOLDERS

GENERAL INFORMATION

When are this proxy statement and the accompanying materials scheduled to be sent to stockholders?

We have elected to provide access to our proxy materials to our stockholders via the Internet. Accordingly, on or about April 30, 2021, we will begin mailing the Notice of Availability. Our proxy materials, including the Notice of the 2021 Annual Meeting of Stockholders, this proxy statement and the accompanying proxy card or, for shares held in street name (i.e., held for your account by a broker, bank or other nominee), a voting instruction form, and the 2020 Annual Report to Stockholders, or the 2020 Annual Report, will be mailed or made available to stockholders on the Internet on or about the same date.

Why did I receive a Notice of Internet Availability of Proxy Materials instead of a full set of proxy materials?

Pursuant to rules adopted by the SEC, for most stockholders, we are providing access to our proxy materials over the Internet rather than printing and mailing our proxy materials. We believe following this process will expedite the receipt of such materials and will help lower our costs and reduce the environmental impact of our proxy materials. Therefore, the Notice of Availability was mailed to holders of record and beneficial owners of our common stock starting on or about April 30, 2021. The Notice of Availability provides instructions as to how stockholders may access and review our proxy materials, including the Notice of the 2021 Annual Meeting of Stockholders, this proxy statement, the proxy card and our 2020 Annual Report, on the website referred to in the Notice of Availability or, alternatively, how to request that a printed copy of the proxy materials, including a proxy card, be sent to them by mail. The Notice of Availability also provides voting instructions. In addition, stockholders of record may request to receive the proxy materials in printed form by mail or electronically by e-mail on an ongoing basis for future stockholder meetings. Please note that, while our proxy materials are available at the website referenced in the Notice of Availability and our Notice of the 2021 Annual Meeting of Stockholders, this proxy statement and our 2020 Annual Report are available on our website, no other information contained on either website is incorporated by reference in, or considered to be a part of, this proxy statement.

Who is soliciting my vote?

Our board of directors is soliciting your vote for the Annual Meeting.

When is the record date for the Annual Meeting?

The record date for determination of stockholders entitled to vote at the Annual Meeting is the close of business on, April 19, 2021.

How many votes can be cast by all stockholders?

There were 45,066,155 shares of our common stock, par value $0.0001 per share, outstanding on April 19, 2021, all of which are entitled to vote with respect to all matters to be acted upon at the Annual Meeting of the Stockholders on June 16, 2021, or the Annual Meeting. Each stockholder of record is entitled to one vote for each share of our common stock held by such stockholder. None of our shares of undesignated preferred stock were outstanding as of April 30, 2021.

3

How do I vote?

If you are a stockholder of record, there are several ways for you to vote your shares.

If the Annual Meeting is adjourned or postponed, the deadlines above may be extended.

If you are a beneficial owner of shares held in “street name” by your broker, bank or other nominee, you should

have received a voting instruction form with these proxy materials from your broker, bank or other nominee rather than from us. The voting deadlines and availability of telephone and Internet voting for beneficial owners of shares will depend on the voting processes of the broker, bank or other nominee that holds your shares. Therefore, we urge you to carefully review and follow the voting instruction form and any other materials that you receive from that organization. If you hold your shares of Kymera Therapeutics common stock in multiple accounts, you should vote your shares as described in each set of proxy materials you receive.

If you submit a proxy without giving voting instructions, your shares will be voted in the manner recommended by the board of directors on all matters presented in this proxy statement, and as the persons named as proxies in the proxy card may determine in their discretion with respect to any other matters properly presented at the Annual Meeting. You may also authorize another person or persons to act for you as proxy in a writing, signed by you or your authorized representative, specifying the details of those proxies’ authority. The original writing must be given to each of the named proxies, although it may be sent to them by electronic transmission if, from that transmission, it can be determined that the transmission was authorized by you.

If any other matters are properly presented for consideration at the Annual Meeting, including, among other things, consideration of a motion to adjourn the Annual Meeting to another time or place (including, without limitation, for the purpose of soliciting additional proxies), the persons named in your proxy and acting thereunder will have discretion to vote on those matters in accordance with their best judgment. We do not currently anticipate that any other matters will be raised at the Annual Meeting.

4

How can I virtually attend the Annual Meeting?

To attend and participate in the Annual Meeting, stockholders will need to access the live webcast of the meeting. To do so, stockholders of record will need to visit www.virtualshareholdermeeting.com/KYMR2021 and enter the control number provided in the Notice of Availability to pre-register for the Annual Meeting prior to the deadline of June 14, 2021 at 5:00 p.m. Eastern Time, and beneficial owners of shares held in street name will need to follow the instructions provided in the voting instructions form by the broker, bank or other nominee that holds their shares.

The live webcast of the Annual Meeting will begin promptly at 8:00 a.m. Eastern Time on June 16, 2021. We encourage stockholders to login to this website and access the webcast before the Annual Meeting’s start time by following the instructions in the email received on the morning of the Annual Meeting. You should allow ample time in advance of the meeting.

Additionally, questions regarding how to attend and participate via the Internet can be answered by following the assistance instructions included at www.virtualshareholdermeeting.com/KYMR2021 or by calling the phone number provided in the email received on the morning of the Annual Meeting.

If you wish to submit a question during the Annual Meeting, you may log into, and submit a question on, the virtual meeting platform using the unique link provided to you via email following the completion of your registration at www.virtualshareholdermeeting.com/KYMR2021 and following the instructions there. Our Annual Meeting will be governed by the Annual Meeting’s Rules of Conduct and will address the ability of stockholders to ask questions during the meeting and rules for how questions will be recognized and addressed. The Annual Meeting’s Rules of Conduct will be posted on www.virtualshareholdermeeting.com/KYMR2021 approximately two weeks prior to the date of the Annual Meeting.

How do I revoke my proxy?

If you are a stockholder of record, you may revoke your proxy by (1) following the instructions on the Notice of Availability and submitting a new vote by Internet, telephone or mail using the procedures described in the “How do I Vote?” section above before the applicable deadline, (2) attending and voting at the Annual Meeting (although attendance at the Annual Meeting will not in and of itself revoke a proxy), or (3) by filing an instrument in writing revoking the proxy or another duly executed proxy bearing a later date with our corporate secretary. Any written notice of revocation or subsequent proxy card must be received by our corporate secretary prior to the taking of the vote at the Annual Meeting. Such written notice of revocation or subsequent proxy card should be hand delivered to our corporate secretary or sent to our principal executive offices at Kymera Therapeutics, Inc., 200 Arsenal Yards Blvd., Suite 230, Watertown, Massachusetts 02472, Attention: Corporate Secretary.

If a broker, bank, or other nominee holds your shares, you must contact such broker, bank, or nominee in order to find out how to change your vote.

How is a quorum reached?

Our Second Amended and Restated Bylaws, or bylaws, provide that a majority of the shares entitled to vote, present in person or represented by proxy, will constitute a quorum for the transaction of business at the Annual Meeting.

Under the General Corporation Law of the State of Delaware, shares that are voted “abstain” or “withheld” and broker “non-votes” are counted as present for purposes of determining whether a quorum is present at the Annual Meeting. If a quorum is not present, the meeting may be adjourned until a quorum is obtained.

5

How is the vote counted?

Under our bylaws, any proposal other than an election of directors is decided by a majority of the votes properly cast for and against such proposal, except where a larger vote is required by law or by our Fourth Amended and Restated Certificate of Incorporation, or certificate of incorporation, or bylaws. Abstentions and broker “non-votes” are not included in the tabulation of the voting results on any such proposal and, therefore, do not have an impact on such proposals. A broker “non-vote” occurs when a nominee holding shares for a beneficial owner does not vote on a particular proposal because the nominee does not have discretionary voting power with respect to that item, and has not received instructions from the beneficial owner.

If your shares are held in “street name” by a broker, bank or other nominee, your broker, bank or other nominee is required to vote your shares according to your instructions. If you do not give instructions to your broker, bank or other nominee, the broker, bank or other nominee will still be able to vote your shares with respect to certain “discretionary” items, but will not be allowed to vote your shares with respect to “non-discretionary” items. Proposal No. 1 is a “non-discretionary” item. If you do not instruct your broker how to vote with respect to this proposal, your broker, bank or other nominee may not vote for this proposal, and those votes will be counted as broker “non-votes.” Proposal No. 2 is considered to be a discretionary item, and your broker, bank or other nominee will be able to vote on this proposal even if it does not receive instructions from you.

To be elected, the directors nominated via Proposal No. 1 must receive a plurality of the votes cast and entitled to vote on the proposal, meaning that the director nominees receiving the most votes will be elected. Shares voting “withheld” have no effect on the election of directors.

Who pays the cost for soliciting proxies?

We are making this solicitation and will pay the entire cost of preparing and distributing the Notice of Availability and our proxy materials and soliciting votes. Our officers and employees may, without compensation other than their regular compensation, solicit proxies through further mailings, personal conversations, facsimile transmissions, e-mails, or otherwise.

How may stockholders submit matters for consideration at an annual meeting?

The required notice must be in writing and received by our corporate secretary at our principal executive offices not later than the close of business on the 90^th day nor earlier than the close of business on the 120^th day prior to the first anniversary of the preceding year’s annual meeting. However, in the event that the date of the annual meeting is convened more than 30 days before or more than 60 days after the first anniversary of the preceding year’s annual meeting, or if no annual meeting were held in the preceding year, a stockholder’s notice must be so received not later than the close of business on the later of (A) the 90^th day prior to the scheduled date of such annual meeting or (B) the tenth day following the day on which public announcement of the date of such annual meeting was first made.

In addition, any stockholder proposal intended to be included in the proxy statement for the next annual meeting of our stockholders in 2022 must also satisfy the requirements of SEC Rule 14a-8 under the Securities Exchange Act of 1934, as amended, or the Exchange Act, and be received not later than December 31, 2021. If the date of the annual meeting is moved by more than 30 days from the date contemplated at the time of the previous year’s proxy statement, then notice must be received within a reasonable time before we begin to print and send proxy materials. If that happens, we will publicly announce the deadline for submitting a proposal in a press release or in a document filed with the SEC.

How can I know the voting results?

We plan to announce preliminary voting results at the Annual Meeting and will publish final results in a Current Report on Form 8-K to be filed with the SEC within four business days following the Annual Meeting.

PROPOSAL NO. 1 — ELECTION OF CLASS I DIRECTORS

Our board of directors currently consists of ten members. In accordance with the terms of our certificate of incorporation and bylaws, our board of directors is divided into three classes, class I, class II and class III, with members of each class serving staggered three-year terms. The members of the classes are divided as follows:

Upon the expiration of the term of a class of directors, directors in that class will be eligible to be elected for a new three-year term at the annual meeting of stockholders in the year in which their term expires.

Our certificate of incorporation and bylaws provide that the authorized number of directors may be changed only by resolution of our board of directors. Our certificate of incorporation also provides that our directors may be removed only for cause by the affirmative vote of the holders of at least two-thirds (2/3) of the outstanding shares then entitled to vote at an annual election of directors, and that any vacancy on our board of directors, including a vacancy resulting from an enlargement of our board of directors, may be filled only by vote of a majority of our directors then in office.

Our board of directors has nominated Pamela Esposito, Ph.D., Gorjan Hrustanovic, Ph.D. and Donald W. Nicholson, Ph.D. for election as the class I directors at the Annual Meeting. Each of the nominees are currently directors, and each has indicated a willingness to continue to serve as a director, if elected.

Andrew Hedin, a member of our board of directors and currently a class I director, informed us in March 2021 that he does not intend to stand for reelection at the Annual Meeting. Mr. Hedin’s intention not to stand for reelection was not the result of any disagreement with the us on any matter relating to our operations, policies or practices.

Our Nominating and Corporate Governance Committee Policies and Procedures for Director Candidates, or the Director Guidelines, provide that the value of diversity should be considered in determining director candidates as well as other factors such as a candidate’s character, judgment, skills, education, expertise and absence of conflicts of interest. Our priority in selection of board members is identification of members who will further the interests of our stockholders through their established records of professional accomplishment, their ability to contribute positively to the collaborative culture among board members, and their knowledge of our business and understanding of the competitive landscape in which we operate and adherence to high ethical standards.

In addition to the information presented below regarding each of the nominees and continuing directors’ specific experience, qualifications, attributes and skills that our board of directors and our nominating and corporate governance committee considered in determining that he or she should serve as a director, we also believe that each of our directors has demonstrated business acumen, integrity and an ability to exercise sound judgment, as well as a commitment of service to Kymera Therapeutics and our board of directors.

Nominees for Election as Class I Directors

The following table identifies our director nominees, and sets forth their principal occupation and business experience during the last five years and their ages as of April 1, 2021.

7

Pamela Esposito, Ph.D. Dr. Esposito has served as a member of our board of directors since September 2020. She has served as Chief Business Officer of Replimune Group, Inc. since 2015. Dr. Esposito is also a member of the board of directors of Accent Therapeutics, a private oncology company. Previous to her position at Replimune, she was Chief Business Officer at Ra Pharmaceuticals, Inc. from 2013 to 2015. As a member of Ra Pharmaceuticals, Inc.’s senior management team, Dr. Esposito played a leadership role in strategy, helping Ra Pharmaceuticals, Inc. transform from a discovery platform to a clinical-stage company. Prior to Ra Pharmaceuticals, Inc., from 2010 to 2011, she was Vice President of Business Development at BioVex Group, Inc. Dr. Esposito earned a Ph.D. in Pharmacology from Tufts University School of Medicine in 2002 and a B.A. in Biochemistry/Molecular Biology from Dartmouth College. We believe Dr. Esposito is qualified to serve on our board of directors because of her extensive experience in the life sciences industry in operational roles for high-growth life science companies.

Gorjan Hrustanovic, Ph.D. Dr. Hrustanovic has served as a member of our board of directors since March 2020. Dr. Hrustanovic is a Managing Director at BVF Partners L.P. where he focuses on biotechnology and therapeutic investments. Dr. Hrustanovic is a member of the board of directors of Olema Pharmaceuticals, Inc., a publicly traded biopharmaceutical company, and serves as a member on the boards of directors of several privately held companies, including Rain Therapeutics, Inc. Dr. Hrustanovic received his B.S. in molecular biology and economics/management science from the University of California, San Diego and a Ph.D. in Biomedical Sciences, Cancer Biology and Cell Signaling from the University of California, San Francisco. We believe Dr. Hrustanovic is qualified to serve as a member of our board of directors due to his experience in the life sciences industry as a venture capitalist and a director.

Donald W. Nicholson, Ph.D. Dr. Nicholson has served as a member of our board of directors since November 2017. Dr. Nicholson is the former chief executive officer of Nimbus Therapeutics, LLC, or Nimbus, serving from August 2014 to October 2018. Prior to joining Nimbus, Dr. Nicholson held various strategic, leadership and operational roles in diverse therapeutic areas, including respiratory, inflammation, immunology, bone, endocrine, urology, infectious disease and neurosciences at Merck from April 1998 to July 2013. Dr. Nicholson has co-authored more than 150 publications in peer-reviewed scientific and medical journals and is internationally recognized for his contributions to the field of apoptotic cell death. He also serves as a member on the board of directors of Generation Bio and is chairman of the board of Disc Medicine, Jnana Therapeutics and NodThera. Dr. Nicholson received his Ph.D. and an Honors B.Sc. degree in Biochemistry from the University of Western Ontario, and trained as a Medical Research Council postdoctoral fellow at the University of Munich in Germany. We believe Dr. Nicholson is qualified to serve as a member of our board of directors due to his extensive experience in leadership positions throughout the life sciences industry and his strong scientific background.

Vote Required and Board of Directors’ Recommendation

The nominees for class I director who receive the most votes (also known as a plurality) will be elected. You may vote either FOR all the nominees, FOR any one of the nominees, WITHHOLD your vote from all the nominees or WITHHOLD your vote from any one of the nominees. Votes that are withheld will not be included in the vote tally for the election of directors. If your shares are held in “street name” by a broker, bank or other nominee, your broker, bank or other nominee does not have authority to vote your unvoted shares held by the firm for the election of directors. As a result, any shares not voted by you will be treated as a broker non-vote. Such broker non-votes will have no effect on the results of this vote.

The proxies will be voted in favor of the above nominees unless a contrary specification is made in the proxy. The nominees have consented to serve as our directors if elected. However, if the nominees are unable to serve or for good cause will not serve as directors, the proxies will be voted for the election of such substitute nominee as our board of directors may designate.

The proposal for the election of directors relates solely to the election of class I directors nominated by our board of directors.

8

The board of directors recommends voting “FOR” the election of Pamela Esposito, Ph.D., Gorjan Hrustanovic, Ph.D. and Donald W. Nicholson, Ph.D. as the class I directors, to serve for a three-year term ending at the annual meeting of stockholders to be held in 2024.

PROPOSAL NO. 2 – RATIFICATION OF THE APPOINTMENT OF ERNST & YOUNG LLP

AS KYMERA THERAPEUTICS’ INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE FISCAL YEAR ENDING DECEMBER 31, 2021

Kymera Therapeutics’ stockholders are being asked to ratify the appointment by the audit committee of the board of directors of Ernst & Young LLP as Kymera Therapeutics’ independent registered public accounting firm for the fiscal year ending December 31, 2021. Ernst & Young LLP has served as Kymera Therapeutics’ independent registered public accounting firm since 2018.

The audit committee is solely responsible for selecting Kymera Therapeutics’ independent registered public accounting firm for the fiscal year ending December 31, 2021. Stockholder approval is not required to appoint Ernst & Young LLP as Kymera Therapeutics’ independent registered public accounting firm. However, the board of directors believes that submitting the appointment of Ernst & Young LLP to the stockholders for ratification is good corporate governance. If the stockholders do not ratify this appointment, the audit committee will reconsider whether to retain Ernst & Young LLP. If the selection of Ernst & Young LLP is ratified, the audit committee, at its discretion, may direct the appointment of a different independent registered public accounting firm at any time it decides that such a change would be in the best interest of Kymera Therapeutics and its stockholders.

A representative of Ernst & Young LLP is expected to be present at the Annual Meeting and will have an opportunity to make a statement if he or she desires to do so and to respond to appropriate questions from our stockholders.

We incurred the following fees from Ernst & Young LLP for the audit of the consolidated financial statements and for other services provided during the years ended December 31, 2020 and 2019.

Audit Committee Pre-approval Policy and Procedures

Our audit committee has adopted policies and procedures relating to the approval of all audit and non-audit services that are to be performed by our independent registered public accounting firm. This policy provides that we will not engage our independent registered public accounting firm to render audit or non-audit services unless the service is specifically approved in advance by our audit committee or the engagement is entered into pursuant to the pre-approval procedure described below.

13

From time to time, our audit committee may pre-approve specified types of services that are expected to be provided to us by our independent registered public accounting firm during the next 12 months. Any such pre-approval details the particular service or type of services to be provided and is also generally subject to a maximum dollar amount.

During fiscal years 2020 and 2019, no services were provided to us by Ernst & Young LLP other than in accordance with the pre-approval policies and procedures described above.

Vote Required and Board of Directors’ Recommendation

The affirmative vote of a majority of the votes cast FOR this proposal is required to ratify the appointment of our independent public accountant. Votes that are withheld will be counted towards the tabulation of votes cast on this proposal and will have the same effect as a negative vote. If your shares are held in “street name” by a broker, bank or other nominee, your broker, bank or other nominee has authority to vote your unvoted shares held by the firm on this proposal. If your broker, bank or other nominee does not exercise this authority, such broker non-votes will have no effect on the results of this vote.

The board of directors recommends voting “FOR” Proposal No. 2 to ratify the appointment of Ernst & Young LLP as Kymera Therapeutics’ independent registered public accounting firm for the fiscal year ending December 31, 2021.

CORPORATE GOVERNANCE

Director Nomination Process

Our nominating and corporate governance committee is responsible for identifying individuals qualified to serve as directors, consistent with criteria approved by our board of directors, and recommending such persons to be nominated for election as directors, except where we are legally required by contract, law or otherwise to provide third parties with the right to nominate.

The process followed by our nominating and corporate governance committee to identify and evaluate director candidates includes requests to board members and others for recommendations, meetings from time to time to evaluate biographical information and background material relating to potential candidates, and interviews of selected candidates by management, recruiters, members of the committee and our board. The qualifications, qualities and skills that our nominating and corporate governance committee believes must be met by a committee recommended nominee for a position on our board of directors are as follows:

Stockholders may recommend individuals to the nominating and corporate governance committee for consideration as potential director candidates. Any such proposals should be submitted to our corporate secretary at our principal executive offices no later than the close of business on the 90^th day nor earlier than the close of business on the 120^th day prior to the one-year anniversary of the date of the preceding year’s annual meeting and should include appropriate biographical and background material to allow the nominating and corporate governance committee to properly evaluate the potential director candidate and the number of shares of our stock beneficially owned by the stockholder proposing the candidate. Stockholder proposals should be addressed to Kymera Therapeutics, Inc., 200 Arsenal Yards Blvd., Suite 230, Watertown, Massachusetts 02472, Attention: Corporate Secretary. Assuming that biographical and background material have been provided on a timely basis in accordance with our bylaws, any recommendations received from stockholders will be evaluated in the same manner as potential nominees proposed by the nominating and corporate governance committee. If our board of directors determines to nominate a stockholder recommended candidate and recommends his or her election, then his or her name will be included on our proxy card for the next annual meeting of stockholders. See “Stockholder Proposals” for a discussion of submitting stockholder proposals.

Director Independence

Applicable Nasdaq Global Market, or Nasdaq, rules require a majority of a listed company’s board of directors to be comprised of independent directors within one year of listing. In addition, the Nasdaq rules require that, subject to specified exceptions, each member of a listed company’s audit, compensation and nominating and corporate governance committees be independent and that audit committee members also satisfy independence criteria set forth in Rule 10A-3 under the Exchange Act and that compensation committee members satisfy independence criteria set forth in Rule 10C-1 under the Exchange Act. Under applicable Nasdaq rules, a director will only qualify as an “independent director” if, in the opinion of the listed company’s board of directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying

15

out the responsibilities of a director. In order to be considered independent for purposes of Rule 10A-3 under the Exchange Act, a member of an audit committee of a listed company may not, other than in his or her capacity as a member of the audit committee, the board of directors, or any other board committee: (i) accept, directly or indirectly, any consulting, advisory, or other compensatory fee from the listed company or any of its subsidiaries, other than compensation for board service; or (ii) be an affiliated person of the listed company or any of its subsidiaries. In addition, in affirmatively determining the independence of any director who will serve on a company’s compensation committee, Rule 10C-1 under the Exchange Act requires that a company’s board of directors must consider all factors specifically relevant to determining whether a director has a relationship to such company which is material to that director’s ability to be independent from management in connection with the duties of a compensation committee member, including, but not limited to: the source of compensation of the director, including any consulting, advisory or other compensatory fee paid by such company to the director, and whether the director is affiliated with the company or any of its subsidiaries or affiliates.

Our board of directors has determined that all members of the board of directors, except Nello Mainolfi, Ph.D., are independent directors, including for purposes of the rules of Nasdaq and the SEC. In making such independence determination, our board of directors considered the relationships that each director has with us and all other facts and circumstances that our board of directors deemed relevant in determining their independence, including the potential deemed beneficial ownership of our capital stock by each director, including non-employee directors that are affiliated with certain of our major stockholders. In considering the independence of the directors listed above, our board of directors considered the association of our directors with the holders of more than 5% of our common stock. There are no family relationships among any of our directors or executive officers. Dr. Mainolfi is not an independent director under these rules because he is currently employed as the chief executive officer of the company.

Board Committees

Our board of directors has established an audit committee, a compensation committee and a nominating and corporate governance committee. Each of the audit committee, compensation committee and nominating and corporate governance committee operates under a charter that satisfies the applicable standards of the SEC and Nasdaq. Each such committee reviews its respective charter at least annually. A current copy of the charter for each of the audit committee, compensation committee, nominating and corporate governance committee is posted on the corporate governance section of our website, https://investors.kymeratx.com/corporate-governance.

The table below shows current membership for each of the standing committees of our board of directors.

Audit Committee

Elena Ridloff, CFA, Andrew Hedin, and Joanna Horobin, M.B., Ch.B. serve on the audit committee, which is chaired by Elena Ridloff, CFA. Our board of directors has determined that each member of the audit committee is “independent” for audit committee purposes as that term is defined by the rules of the SEC and Nasdaq, and that each has sufficient knowledge in financial and auditing matters to serve on the audit committee. Our board of directors has designated Elena Ridloff, CFA as an “audit committee financial expert,” as defined under the applicable rules of the SEC. During the fiscal year ended December 31, 2020, the audit committee met four

16

times. Effective upon Mr. Hedin’s resignation as a director, our board of directors expects to appoint a new member to the audit committee who is also “independent” for audit committee purposes as that term is defined by the rules of the SEC and Nasdaq. The audit committee’s responsibilities include:

All audit and non-audit services, other than de minimis non-audit services, to be provided to us by our independent registered public accounting firm must be approved in advance by our audit committee.

Compensation Committee

Steven Hall, Ph.D., Jeffrey Albers, J.D., MBA and Donald W. Nicholson, Ph.D. serve on the compensation committee, which is chaired by Steven Hall, Ph.D. Our board of directors has determined that each member of the compensation committee is “independent” as defined in the applicable Nasdaq rules. During the fiscal year ended December 31, 2020, the compensation committee met two times and acted via written consent two times. The compensation committee’s responsibilities include:

17

Nominating and Corporate Governance Committee

Bruce Booth, D. Phil., Pamela Esposito, Ph.D., Joanna Horobin, M.B., Ch.B. and Gorjan Hrustanovic, Ph.D. serve on the nominating and corporate governance committee, which is chaired by Bruce Booth, D.Phil. Our board of directors has determined that each member of the nominating and corporate governance committee is “independent” as defined in the applicable Nasdaq rules. During the fiscal year ended December 31, 2020, the nominating and corporate governance committee acted via written consent one time. The nominating and corporate governance committee’s responsibilities include:

The nominating and corporate governance committee considers candidates for board of director membership suggested by its members and our chief executive officer. Additionally, in selecting nominees for directors, the nominating and corporate governance committee will review candidates recommended by stockholders in the same manner and using the same general criteria as candidates recruited by the committee and/or recommended by our board of directors. Any stockholder who wishes to recommend a candidate for consideration by the committee as a nominee for director should follow the procedures described later in this proxy statement under the heading “Stockholder Proposals.” The nominating and corporate governance committee will also consider whether to nominate any person proposed by a stockholder in accordance with the provisions of our bylaws relating to stockholder nominations as described later in this proxy statement under the heading “Stockholder Proposals.”

Identifying and Evaluating Director Nominees. Our board of directors is responsible for filling vacancies on our board of directors and for nominating candidates for election by our stockholders each year in the class of directors whose term expires at the relevant annual meeting. The board of directors delegates the selection and

18

nomination process to the nominating and corporate governance committee, with the expectation that other members of the board of directors, and of management, will be requested to take part in the process as appropriate.

Generally, the nominating and corporate governance committee identifies candidates for director nominees in consultation with management, through the use of search firms or other advisors, through the recommendations submitted by stockholders or through such other methods as the nominating and corporate governance committee deems to be helpful to identify candidates. Once candidates have been identified, the nominating and corporate governance committee confirms that the candidates meet all of the minimum qualifications for director nominees established by the nominating and corporate governance committee. The nominating and corporate governance committee may gather information about the candidates through interviews, detailed questionnaires, comprehensive background checks or any other means that the nominating and corporate governance committee deems to be appropriate in the evaluation process. The nominating and corporate governance committee then meets as a group to discuss and evaluate the qualities and skills of each candidate, both on an individual basis and taking into account the overall composition and needs of our board of directors. Based on the results of the evaluation process, the nominating and corporate governance committee recommends candidates for the board of directors’ approval to fill a vacancy or as director nominees for election to the board of directors by our stockholders each year in the class of directors whose term expires at the relevant annual meeting.

Board and Committee Meetings Attendance

The full board of directors met six times and acted via written consent seven times during 2020. During 2020, each member of the board of directors attended in person or participated in 75% or more of the aggregate of (i) the total number of meetings of the board of directors (held during the period for which such person has been a director), and (ii) the total number of meetings held by all committees of the board of directors on which such person served (during the periods that such person served).

Director Attendance at Annual Meeting of Stockholders

Directors are responsible for attending the annual meeting of stockholders to the extent practicable. We did not hold an annual meeting of stockholders during the time we were a public company in 2020.

Policy on Trading, Pledging and Hedging of Company Stock

Certain transactions in our securities (such as purchases and sales of publicly traded put and call options, and short sales) create a heightened compliance risk or could create the appearance of misalignment between management and stockholders. In addition, securities held in a margin account or pledged as collateral may be sold without consent if the owner fails to meet a margin call or defaults on the loan, thus creating the risk that a sale may occur at a time when an officer or director is aware of material, non-public information or otherwise is not permitted to trade in Company securities. Our insider trading policy expressly prohibits derivative transactions of our stock by our executive officers, directors and employees. Our insider trading policy expressly prohibits purchases of any derivative securities that provide the economic equivalent of ownership.

Code of Business Conduct and Ethics

We have adopted a written code of business conduct and ethics that applies to our directors, officers and employees, including our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions. A current copy of the code is posted on the corporate governance section of our website, which is located at https://investors.kymeratx.com/corporate-governance. If we make any substantive amendments to, or grant any waivers from, the code of business conduct and ethics for any officer or director, we will disclose the nature of such amendment or waiver on our website or in a current report on Form 8-K.

19

Board Leadership Structure and Board’s Role in Risk Oversight

Currently, the role of chairperson of the board is separated from the role of chief executive officer, and we plan to keep these roles separate. We believe that separating these positions allows our chief executive officer to focus on our day-to-day business, while allowing the chairperson of the board to lead the board of directors in its fundamental role of providing advice to and independent oversight of management. Our board of directors recognizes the time, effort, and energy that the chief executive officer is required to devote to his position in the current business environment, as well as the commitment required to serve as our chairperson, particularly as the board of directors’ oversight responsibilities continue to grow. While our bylaws and our corporate governance guidelines do not require that our chairperson and chief executive officer positions be separate, our board of directors believes that having separate positions is the appropriate leadership structure for us at this time and demonstrates our commitment to good corporate governance.

Risk is inherent to every business, and how well a business manages risk can ultimately determine its success. We face a number of risks, including risks relating to our financial condition, development and commercialization activities, operations, strategic direction and intellectual property. Management is responsible for the day-to-day management of risks we face, while our board of directors, as a whole and through its committees, has responsibility for the oversight of risk management. In its risk oversight role, our board of directors has the responsibility to satisfy itself that the risk management processes designed and implemented by management are adequate and functioning as designed.

The role of the board of directors in overseeing the management of our risks is conducted primarily through committees of the board of directors, as disclosed in the descriptions of each of the committees above and in the charters of each of the committees. The full board of directors (or the appropriate board committee in the case of risks that are under the purview of a particular committee) discusses with management our major risk exposures, their potential impact on us, and the steps we take to manage them. When a board committee is responsible for evaluating and overseeing the management of a particular risk or risks, the chairperson of the relevant committee reports on the discussion to the full board of directors during the committee reports portion of the next board meeting. This enables the board of directors and its committees to coordinate the risk oversight role, particularly with respect to risk interrelationships.

Communication with the Directors of Kymera Therapeutics

Any interested party with concerns about our company may report such concerns to the board of directors or the chairperson of our board of directors and nominating and corporate governance committee, by submitting a written communication to the attention of such director at the following address:

c/o Kymera Therapeutics, Inc.

200 Arsenal Yards Blvd., Suite 230

Watertown, Massachusetts 02472

United States

You may submit your concern anonymously or confidentially by postal mail. You may also indicate whether you are a stockholder, customer, supplier or other interested party.

A copy of any such written communication may also be forwarded to Kymera Therapeutics’ legal counsel and a copy of such communication may be retained for a reasonable period of time. The director may discuss the matter with Kymera Therapeutics’ legal counsel, with independent advisors, with non-management directors, or with Kymera Therapeutics’ management, or may take other action or no action as the director determines in good faith, using reasonable judgment and applying his or her own discretion.

Communications may be forwarded to other directors if they relate to important substantive matters and include suggestions or comments that may be important for other directors to know. In general, communications relating

20

to corporate governance and long-term corporate strategy are more likely to be forwarded than communications relating to ordinary business affairs, personal grievances and matters as to which we tend to receive repetitive or duplicative communications.

The audit committee oversees the procedures for the receipt, retention, and treatment of complaints received by Kymera Therapeutics regarding accounting, internal accounting controls, or audit matters, and the confidential, anonymous submission by employees of concerns regarding questionable accounting, internal accounting controls or auditing matters. Kymera Therapeutics has also established a third-party website, https://whistleblowerservices.com/kymeratx, and toll-free telephone number, (877) 306-2141, for the reporting of such activity.

Director Compensation

The table below shows all compensation earned by or paid to our non-employee directors during the year ended December 31, 2020. Nello Mainolfi, Ph.D., our chief executive officer, does not receive any compensation for his services as director and, consequently, is not included in this table. The compensation received by Dr. Mainolfi during 2020 is set forth in the section of this Proxy Statement captioned “Executive Compensation — Summary Compensation Table.”

21

Under our director compensation program, we pay our non-employee directors a cash retainer for service on the board of directors and for service on each committee on which the director is a member. The chairperson of each committee receives a higher retainer for such service. The fees paid to non-employee directors for service on the board of directors and for service on each committee of the board of directors on which the director is a member are as follows:

We also reimburse our non-employee directors for reasonable out-of-pocket expenses incurred by our non-employee directors in connection with attending our meetings of the board of directors and committees thereof.

In addition, each new non-employee director elected to our board of directors will be granted an option to purchase 40,127 shares of our common stock on the date of such director’s election or appointment to the board of directors, which will vest ratably in 36 equal monthly installments following the grant date, subject to the director’s continued service on our board of directors through such vesting date. On the date of each annual meeting of stockholders of our company, each continuing non-employee director will be granted an option to purchase 20,063 shares of our common stock, which will vest in full upon the earlier to occur of the first anniversary of the date of grant or the date of the next annual meeting, subject to the director’s continued service on our board of directors through such vesting date.

This program is intended to provide a total compensation package that enables us to attract and retain qualified and experienced individuals to serve as directors and to align our directors’ interests with those of our stockholders.

Executive Compensation

Our named executive officers for the year ended December 31, 2020 are as follows:

22

Summary Compensation Table

The following table presents the compensation awarded to, earned by or paid to each of our named executive officers for the years indicated. On August 20, 2020, we effected a 1-for-1.5949 reverse stock split of our issued and outstanding shares of common stock. Accordingly, all share and per share amounts for all periods presented in this proxy statement have been adjusted retroactively, where applicable, to reflect this reverse stock split.

Narrative to Summary Compensation Table

Our board of directors and compensation committee review compensation annually for our executive officers. In setting executive base salaries and annual incentives and granting equity incentive awards, we consider compensation for comparable positions in the market, the historical compensation levels of our executives, individual performance as compared to our expectations and objectives, our desire to motivate our employees to achieve short- and long-term results that are in the best interests of our stockholders, and a long-term commitment to our company. We target a general competitive position, based on independent third-party benchmark analytics to inform the mix of compensation of base salary, annual incentives or long-term incentives.

Our compensation committee is responsible for determining the compensation for all executive officers other than our chief executive officer. Our board of directors, with the recommendation of the compensation committee, is responsible for determining the compensation of our chief executive officer. Our compensation committee typically reviews and discusses management’s proposed compensation with the chief executive officer for all executives other than the chief executive officer. Based on those discussions and its discretion, taking into account the factors noted above, the compensation committee then sets the compensation for each executive officer other than the chief executive officer and recommends the compensation for the chief executive officer to our board of directors for approval. Our board of directors discusses the compensation committee’s recommendation and ultimately approves the compensation of our chief executive officer without members of management present.

23

In 2020, the compensation committee retained the services of Radford as its external independent compensation consultant. The board of directors and the compensation committee considered Radford’s input on certain compensation matters as they deemed appropriate.

Base salary

Each named executive officer’s base salary is a fixed component of annual compensation for performing specific duties and functions, and has been established by our board of directors taking into account each individual’s role, responsibilities, skills, and expertise. Base salaries for our named executive officers are reviewed, typically in connection with our annual performance review process, approved by our board of directors, and adjusted from time to time to realign salaries with market levels after taking into account individual responsibilities, performance and experience.

At December 31, 2020, the base salaries for each of Dr. Mainolfi, Dr. Chesworth and Dr. Gollob were $541,300, $382,000 and $425,000, respectively.

Annual bonus

Our named executive officers, as well as other executive officers, are eligible to participate in our Senior Executive Cash Incentive Bonus Plan, or the Bonus Plan, which is an annual bonus program intended to reward our named executive officers for meeting objective or subjective performance goals for a fiscal year. The Bonus Plan provides for cash payments based upon the attainment of performance targets established by the compensation committee, which may relate to financial and operational measures or objectives, as well as individual performance objectives. Each executive officer who is selected to participate in the Bonus Plan will have a target bonus opportunity set for each performance period.

With respect to performance in 2020, the target bonus opportunity as a percentage of base salary for Dr. Mainolfi was 50% and, for each of Dr. Chesworth and Dr. Gollob, was 40%. Our board of directors evaluated the Company’s performance against the corporate objectives for each year and determined that, based on the level of achievement in 2020, each of our named executive officers earned annual bonuses in the amounts as set forth above in the “Summary Compensation Table.”

Equity Compensation

Although we do not have a formal policy with respect to the grant of equity incentive awards to our executive officers, we believe that equity grants provide our executives with a strong link to our long-term performance, create an ownership culture and help to align the interests of our executives and our stockholders. In addition, we believe that equity grants promote executive retention because they incentivize our executive officers to remain in our employment during the vesting period. Accordingly, our board of directors periodically reviews the equity incentive compensation of our named executive officers and may grant equity incentive awards to them from time to time. During the fiscal year ended December 31, 2020, we granted our named executive officers certain options to purchase shares of our common stock, as described in more detail in the “Outstanding Equity Awards at 2020 Fiscal Year-end” table below.

401(k) Plan

We participate in a retirement savings plan, or 401(k) plan, that is intended to qualify for favorable tax treatment under Section 401(a) of the Code, and contains a cash or deferred feature that is intended to meet the requirements of Section 401(k) of the Code. U.S. employees who are at least 21 years of age are generally eligible to participate in the 401(k) plan, subject to certain criteria. We have implemented a safe harbor match under our 401(k) plan of 100% of the first 3% and 50% of the next 2%, for a total match of 4% of the first 5%. Participants may make pre-tax and certain after-tax (Roth) salary deferral contributions to the plan from their

24

eligible earnings up to the statutorily prescribed annual limit under the Code. Participants who are 50 years of age or older may contribute additional amounts based on the statutory limits for catch-up contributions. Participant contributions are held in trust as required by law. An employee’s interest in his or her salary deferral contributions, inclusive of the safe harbor match described above, is 100% vested when contributed. We have the ability to make discretionary contributions under the plan but did not make any contributions in 2020 or 2019.

Health and Welfare Benefits

All of our full-time employees, including our named executive officers, are eligible to participate in certain medical, disability and life insurance benefit programs offered by us. We pay the premiums for term life insurance and long-term disability for all of our employees.

Rule 10b5-1 Sales Plans

Our directors and executive officers may adopt written plans, known as Rule 10b5-1 plans, in which they will contract with a broker to buy or sell shares of our common stock on a periodic basis. Under a Rule 10b5-1 plan, a broker executes trades pursuant to parameters established by the director or officer when entering into the plan, without further direction from the director or officer. The director or officer may terminate the plan in some circumstances. Our directors and executive officers may also buy or sell additional shares outside of a Rule 10b5-1 plan when they are not in possession of material, nonpublic information.

Outstanding Equity Awards at 2020 Fiscal Year-End Table

The following table presents information regarding all outstanding equity awards held by each of our named executive officers as of December 31, 2020. All equity awards in the table below were granted under our 2018 Stock Option and Grant Plan and 2020 Stock Option and Incentive Plan.

Employment Arrangements with Our Named Executive Officers

We have entered into employment agreements with each of our named executive officers. Each of our named executive officers is employed “at will”. In addition, each of our named executive officers previously entered into our standard confidential information, invention assignment, nonsolicitation and noncompetition agreement, which continues to remain in effect and contains protections of confidential information, requires the assignment of inventions and contains other restrictive covenants.

Nello Mainolfi

On August 25, 2020, we entered into an employment agreement with Dr. Mainolfi, who currently serves as our Founder, President and Chief Executive Officer. Dr. Mainolfi’s current base salary is $568,500, which is subject to periodic review and adjustment, and he will be eligible to earn an annual bonus with a target amount equal to 50% of his base salary. Dr. Mainolfi is also eligible to participate in the employee benefit plans available to our employees, subject to the terms of those plans. Dr. Mainolfi’s employment agreement provides that Kymera Therapeutics will cause Dr. Mainolfi to be nominated for election to our board of directors and to be recommended to our stockholders for election to our board of directors as long as Dr. Mainolfi remains our Chief Executive Officer. Dr. Mainolfi is also entitled to reimbursement for all reasonable expenses incurred during the term of his employment, in accordance with the policies and procedures then in effect.

Dr. Chesworth is also eligible to participate in the employee benefit plans available to our employees, subject to the terms of those plans. Dr. Chesworth is also entitled to reimbursement for all reasonable expenses incurred during the term of his employment, in accordance with the policies and procedures then in effect.

Jared Gollob

On August 25, 2020, we entered into an employment agreement with Dr. Gollob, who currently serves as our Chief Medical Officer. Dr. Gollob’s current annual base salary is $431,000, which is subject to periodic review and adjustment, and he will be eligible to earn an annual bonus with a target amount equal to 40% of his base salary. Dr. Gollob is also eligible to participate in the employee benefit plans available to our employees, subject to the terms of those plans. Dr. Gollob is also entitled to reimbursement for all reasonable expenses incurred during the term of his employment, in accordance with the policies and procedures then in effect. Dr. Gollob’s severance and change in control entitlements are described below under “Severance and Change in Control.”

Severance and Change in Control

Pursuant to the employment agreements described above, each of our named executive officers is subject to severance and change in control provisions. Each employment agreement provides that upon (i) a termination of the executive’s employment by us for any reason other than for “cause” (as defined in the respective employment agreement) or (ii) a resignation for “good reason” (as defined in the respective employment agreement), in each case outside of the “change in control period” (i.e., in the case of Dr. Mainolfi, the period beginning 3 months

26

prior to and ending 12 months after, a change in control of the Company (as defined in the respective employment agreement), and in the case of Dr. Chesworth and Dr. Gollob, the period beginning in anticipation of, and ending 12 months after, a change in control of the Company), such executive will be entitled to receive, subject to the execution and delivery of an effective separation agreement and release, which shall include a release of claims in favor of Kymera Therapeutics, (A) in the case of Dr. Mainolfi, an amount equal to the sum of 12 months of Dr. Mainolfi’s then current base salary, and in the case of Dr. Chesworth and Dr. Gollob, an amount equal to the sum of 9 months of each of their respective base salaries, (B) the employer portion of the premiums for health insurance benefits continuation under the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended, or COBRA, for up to 12 months in the case of Dr. Mainolfi and for up to 9 months in the case of Dr. Chesworth and Dr. Gollob and (C) for Dr. Mainolfi, accelerated vesting of 25% of the unvested portion of all stock options and other stock-based awards subject solely to time-based vesting, with such accelerated vesting to be effective as of the later of (y) the date of termination of employment and (z) the effective date of the separation agreement and release.

Each employment agreement also provides that upon (i) a termination of the executive’s employment by us other than for cause or (ii) a resignation for good reason, in each case, within the change in control period described above, the executive will be entitled to receive, subject to the execution and delivery of an effective separation agreement and release, which shall include a release of claims in favor of Kymera Therapeutics, (A) a lump sum payment equal to 1.5x, in the case of Dr. Mainolfi, or 1x, in the case of Dr. Chesworth and Dr. Gollob, the sum of such executive’s then-current annual base salary and target bonus opportunity, in the case of each of (A) and (B), payable or commencing payment within 60 days following the date of termination of employment, (B) the employer portion of the premiums for health insurance benefits continuation under COBRA for up to 18 months for Dr. Mainolfi and for up to 12 months for each of Dr. Chesworth and Dr. Gollob and (C) accelerated vesting of all stock options and any other stock-based awards subject solely to time-based vesting, as of the later of (y) the date of termination of employment and (z) the effective date of the separation agreement and release.

The payments and benefits provided under the applicable employment agreement in connection with a change in control may not be eligible for a federal income tax deduction by us pursuant to Section 280G of the Code, and may also subject the applicable named executive officer to an excise tax under Section 4999 of the Code. If the payments or benefits payable in connection with a change in control would be subject to the excise tax imposed under Section 4999 of the Code, then those payments or benefits will be reduced if such reduction would result in a higher net after-tax benefit to the executive officer.

Compensation Risk Assessment

We believe that although a portion of the compensation provided to our named executive officers and other employees is performance-based, our executive compensation program does not encourage excessive or unnecessary risk taking. This is primarily due to the fact that our compensation programs are designed to encourage our executive officers and other employees to remain focused on both short-term and long-term strategic goals. As a result, we do not believe that our compensation programs are reasonably likely to have a material adverse effect on us.

Such fees were payable pursuant to invoices submitted to us by Atlas from time to time. None of these consulting fees were paid directly to Dr. Booth. The consulting fees paid to Atlas did not exceed five percent of the consolidated gross revenue of Atlas during the 2019 fiscal year.

Collaboration Agreements

Vertex Collaboration Agreement

On May 9, 2019, we entered into a collaboration agreement with Vertex setting forth a strategic research and development program between the parties to advance small molecule protein degraders against multiple targets.

The management rights letters provide for certain information rights and rights to consult with our management. These stockholder agreements and the management rights letters terminated upon the closing of our initial public offering in August 2020, except for the registration rights granted under our investors’ rights agreement,

Indemnification Agreements

In connection with our initial public offering in August 2020, we entered into new agreements to indemnify our directors and executive officers. These agreements, among other things, require us to indemnify these individuals for certain expenses (including attorneys’ fees), judgments, fines and settlement amounts reasonably incurred by such person in any action or proceeding, including any action by or in our right, on account of any services undertaken by such person on behalf of our company or that person’s status as a member of our board of directors to the maximum extent allowed under Delaware law.

Policies for Approval of Related Party Transactions

Our board of directors reviews and approves transactions with directors, officers and holders of five percent or more of our voting securities and their affiliates, each a related party. Prior to our initial public offering in August 2020, the material facts as to the related party’s relationship or interest in the transaction were disclosed to our board of directors prior to their consideration of such transaction, and the transaction was not considered approved by our board of directors unless a majority of the directors who are not interested in the transaction approved the transaction. Further, when stockholders are entitled to vote on a transaction with a related party, the material facts of the related party’s relationship or interest in the transaction were disclosed to the stockholders, who must approve the transaction in good faith.

In connection with our initial public offering in August 2020, we adopted a written related party transactions policy that provides that such transactions must be approved by our audit committee. This policy became effective on August 20, 2020. Pursuant to this policy, the audit committee has the primary responsibility for reviewing and approving or disapproving “related party transactions,” which are transactions between us and related persons in which the aggregate amount involved exceeds or may be expected to exceed $120,000 and in which a related person has or will have a direct or indirect material interest. For purposes of this policy, a related person will be defined as a director, executive officer, nominee for director, or greater than 5% beneficial owner of our common stock, in each case since the beginning of the most recently completed year, and their immediate family members.

PRINCIPAL STOCKHOLDERS

The following table sets forth information, to the extent known by us or ascertainable from public filings, with respect to the beneficial ownership of our common stock as of March 31, 2021 by:

The column entitled “Shares Beneficially Owned” is based on a total of 44,971,050 shares of our common stock outstanding as of March 31, 2021.

We have determined beneficial ownership in accordance with the rules of the SEC, and the information is not necessarily indicative of beneficial ownership for any other purpose. These rules generally attribute beneficial ownership of securities to persons who possess sole or shared voting power or investment power with respect to those securities as well as any shares of common stock that the person has the right to acquire within 60 days of March 31, 2021 through the exercise of stock options or other rights. These shares are deemed to be outstanding and beneficially owned by the person holding those options for the purpose of computing the percentage ownership of that person, but they are not treated as outstanding for the purpose of computing the percentage ownership of any other person. Unless otherwise indicated, the persons or entities identified in this table have sole voting and investment power with respect to all shares shown as beneficially owned by them.

REPORT OF THE AUDIT COMMITTEE

The audit committee is appointed by the board of directors to assist the board of directors in fulfilling its oversight responsibilities with respect to (1) the integrity of Kymera Therapeutics’ financial statements, (2) Kymera Therapeutics’ compliance with legal and regulatory requirements, (3) the qualifications, independence and performance of Kymera Therapeutics’ independent auditors engaged for the purpose of preparing or issuing an audit report or performing other audit, review or attest services for Kymera Therapeutics and (4) other matters as set forth in the charter of the audit committee approved by the board of directors.

Management is responsible for the preparation of Kymera Therapeutics’ financial statements and the financial reporting process, including its system of internal control over financial reporting and its disclosure controls and procedures. The independent registered public accounting firm is responsible for performing an audit of Kymera Therapeutics’ financial statements in accordance with the standards of the Public Company Accounting Oversight Board, or the PCAOB, and issuing a report thereon. The audit committee’s responsibility is to monitor and oversee these processes.

In connection with these responsibilities, the audit committee reviewed and discussed with management and the independent registered public accounting firm the audited consolidated financial statements of Kymera Therapeutics for the fiscal year ended December 31, 2020. The audit committee also discussed with the independent registered public accounting firm the matters required to be discussed by the PCAOB’s Auditing Standard No. 1301, Communication with Audit Committees. In addition, the audit committee received written communications from the independent registered public accounting firm confirming their independence as required by the applicable requirements of the PCAOB and has discussed with the independent registered public accounting firm their independence.

Based on the reviews and discussions referred to above, the audit committee recommended to the board of directors that the audited consolidated financial statements of Kymera Therapeutics be included in Kymera Therapeutics’ Annual Report on Form 10-K for the fiscal year ended December 31, 2020, that was filed with the SEC. The information contained in this report shall not be deemed to be (1) “soliciting material,” (2) “filed” with the SEC, (3) subject to Regulations 14A or 14C of the Exchange Act, or (4) subject to the liabilities of Section 18 of the Exchange Act. This report shall not be deemed incorporated by reference into any of our other filings under the Exchange Act or the Securities Act, except to the extent that we specifically incorporate it by reference into such filing.

HOUSEHOLDING

Some banks, brokers and other nominee record holders may be participating in the practice of “householding” proxy statements and annual reports. This means that only one copy of our documents, including the annual report to stockholders and proxy statement, may have been sent to multiple stockholders in your household. We will promptly deliver a separate copy of either document to you upon written or oral request to Kymera Therapeutics, Inc., 200 Arsenal Yards Blvd., Suite 230, Watertown, Massachusetts 02472, Attention: Corporate Secretary, telephone: 857-285-5300. If you want to receive separate copies of the proxy statement or annual report to stockholders in the future, or if you are receiving multiple copies and would like to receive only one copy per household, you should contact your bank, broker or other nominee record holder, or you may contact us at the above address and phone number.

STOCKHOLDER PROPOSALS

A stockholder who would like to have a proposal considered for inclusion in our 2022 proxy statement must submit the proposal in accordance with the procedures outlined in Rule 14a-8 of the Exchange Act so that it is received by us no later than December 31, 2021. However, if the date of the 2022 Annual Meeting of Stockholders is changed by more than 30 days from the date of the previous year’s meeting, then the deadline is a reasonable time before we begin to print and send our proxy statement for the 2022 Annual Meeting of Stockholders. SEC rules set standards for eligibility and specify the types of stockholder proposals that may be excluded from a proxy statement. Stockholder proposals should be addressed to Kymera Therapeutics, Inc., 200 Arsenal Yards Blvd., Suite 230, Watertown, Massachusetts 02472, Attention: Corporate Secretary.

If a stockholder wishes to propose a nomination of persons for election to our board of directors or present a proposal at an annual meeting but does not wish to have the proposal considered for inclusion in our proxy statement and proxy card, our bylaws establish an advance notice procedure for such nominations and proposals. Stockholders at an annual meeting may only consider proposals or nominations specified in the notice of meeting or brought before the meeting by or at the direction of the board of directors or by a stockholder of record on the record date for the meeting, who is entitled to vote at the meeting and who has delivered timely notice in proper form to our corporate secretary of the stockholder’s intention to bring such business before the meeting.

The required notice must be in writing and received by our corporate secretary at our principal executive offices not later than the close of business on the 90^th day nor earlier than the close of business on the 120^th day prior to the first anniversary of the preceding year’s annual meeting. However, in the event that the date of the annual meeting is convened more than 30 days before or more than 60 days after the first anniversary of the preceding year’s annual meeting, or if no annual meeting were held in the preceding year, a stockholder’s notice must be so received not later than the close of business on the later of (A) the 90^th day prior to the scheduled date of such annual meeting or (B) the tenth day following the day on which public announcement of the date of such annual meeting was first made. For stockholder proposals to be brought before the 2022 Annual Meeting of Stockholders, the required notice must be received by our corporate secretary at our principal executive offices not later than March 18, 2022 and no earlier than February 16, 2022. Stockholder proposals and the required notice should be addressed to Kymera Therapeutics, Inc., 200 Arsenal Yards Blvd., Suite 230, Watertown, Massachusetts 02472, Attention: Corporate Secretary.

Our board of directors does not know of any other matters to be brought before the Annual Meeting.
