4.To consider and vote upon, on an advisory basis, whether the stockholder vote to approve the compensation of the named executive officers as required by Section 14A(a)(2) of the Securities Exchange Act of 1934, as amended, should occur every one, two or three years; and

5.To transact such other business as may be properly brought before the meeting or any adjournment or postponement thereof.

As noted above, due to the continuing public health impact of the COVID-19 pandemic, for the safety of all of employees and stockholders and taking into account federal, state and local guidance that has been issued, our annual meeting will be a virtual meeting of stockholders, which will be conducted solely by remote communication via a live webcast. There will not be a physical meeting location, and stockholders will not be able to attend the annual meeting in person. This means that you can attend the annual meeting online, vote your shares during the online meeting and submit questions for consideration at the online meeting. To be admitted to the annual meeting's live webcast, you must register at www.proxydocs.com/GOSS by 8:00 p.m. Eastern Time on June 8, 2021, or the Registration Deadline, as described in the Notice of Internet Availability of Proxy Materials or proxy card.

Our board of directors has fixed the close of business on April 19, 2021 as the record date for the determination of stockholders entitled to notice of and to vote at the annual meeting or any adjournment or postponement thereof.

We have elected to take advantage of Securities and Exchange Commission rules that allow companies to furnish proxy materials to their stockholders by providing access to these documents on the Internet instead of mailing printed copies. Those rules allow a company to provide its stockholders with the information they need, while lowering the costs of delivery and reducing the environmental impact of the annual meeting. Most of our stockholders will not receive printed copies of our proxy materials unless requested, but instead will receive a notice with instructions on how they may access and review our proxy materials on the Internet and how they may cast their vote via the Internet. If you would like to receive a printed or e-mail copy

of our proxy materials, please follow the instructions for requesting the materials in the Notice of Internet Availability that is being sent to you.

Your vote is important. Whether or not you expect to attend our virtual annual meeting, please vote as soon as possible. If you received the Notice of Internet Availability, a proxy card was not sent to you and you may vote only via the Internet unless you attend the virtual annual meeting, in which case you may vote during the virtual annual meeting by following the registration instructions outlined above, or request that a proxy card and proxy materials be mailed to you. If you have requested that a proxy card and proxy materials be mailed to you, and you have received those materials, then you may vote via the Internet, by telephone or by mailing a completed proxy card. For specific voting instructions, please refer to the information provided in the accompanying Proxy Statement and in the Notice of Internet Availability.

The board of directors of Gossamer Bio, Inc. is soliciting the enclosed proxy for use at the annual meeting of stockholders on June 9, 2021 at 9:00 a.m., Pacific Time. The annual meeting will be a completely virtual meeting, which will be conducted via live webcast.

Important Notice Regarding the Availability of Proxy Materials for the Annual Meeting of Stockholders to be Held on June 9, 2021:

This proxy statement and our Annual Report on Form 10-K are available electronically at http://www.proxydocs.com/GOSS.

GENERAL INFORMATION ABOUT THE ANNUAL MEETING AND VOTING

Why am I receiving these materials?

We have prepared these proxy materials, including this proxy statement and the related proxy card, because our board of directors is soliciting your proxy to vote at the 2021 annual meeting of stockholders. This proxy statement summarizes information related to your vote at the annual meeting. All stockholders who find it convenient to do so are cordially invited to attend the annual meeting virtually via live webcast. However, you do not need to attend the meeting to vote your shares. Instead, you may simply submit your proxy via the Internet in accordance with the instructions provided on the Notice of Internet Availability of Proxy Materials or if you elected to receive printed copies of the proxy materials, you may submit your proxy via telephone by completing, signing and returning the enclosed proxy card.

The proxy materials were first sent or made available to our stockholders on or about April 27, 2021.

How can I attend the annual meeting?

This year’s annual meeting will be accessible only through the Internet via a live webcast. We adopted a virtual only format for our annual meeting, in light of the on-going nature of the COVID-19 pandemic, and in the best interests of public health and the health and safety of our stockholders, directors and employees.

You are entitled to participate in the annual meeting if you were a stockholder as of the close of business on our record date of April 19, 2021 or hold a valid proxy for the meeting. To be admitted to the annual meeting’s live webcast, you must register at www.proxydocs.com/GOSS by 8:00 p.m. Eastern Time by June 8, 2021, or the Registration Deadline, as described in the Notice of Internet Availability of Proxy Materials or proxy card. As part of the registration process, you must enter the Control Number shown on your Notice of Internet Availability of Proxy Materials or proxy card. After completion of your registration by the Registration Deadline, further instructions, including a unique link to access the annual meeting, will be emailed to you.

This year's stockholders’ question and answer session will include questions submitted in advance of the annual meeting. You may submit a question in advance of the meeting as a part of the registration process. To register, please visit www.proxydocs.com/GOSS and follow the registration link provided. When prompted please enter the control number found on the proxy materials received. Questions pertinent to meeting matters and that are submitted in accordance with our Rules of Conduct for the annual meeting will be answered during the meeting, subject to applicable time constraints.

Why did I receive a one-page notice in the mail regarding the Internet availability of proxy materials instead of a full set of proxy materials?

In accordance with rules of the Securities and Exchange Commission, or SEC, we use the Internet as the primary means of furnishing proxy materials to our stockholders. Accordingly, we are sending a Notice of Internet Availability of Proxy Materials to our stockholders with instructions on how to access the proxy materials over the Internet or request a printed copy of the materials, and for voting over the Internet.

Stockholders may follow the instructions in the Notice of Internet Availability of Proxy Materials to elect to receive future proxy materials in print by mail or electronically by email. We encourage our stockholders to take advantage of the availability of the proxy materials on the Internet to help reduce the environmental impact of our annual meetings and reduce the cost to us associated with the printing and mailing of materials.

Who can vote at the annual meeting?

Only stockholders of record at the close of business on the record date for the 2021 annual meeting, April 19, 2021, are entitled to vote at the annual meeting. At the close of business on this record date, there were 75,909,708 shares of our common stock outstanding. Common stock is our only class of stock entitled to vote.

Stockholders of Record: Shares Registered in Your Name

If, on the record date, your shares were registered directly in your name with the transfer agent for our common stock, Computershare Trust Company, N.A., then you are a stockholder of record. As a stockholder of record, you may vote at the annual meeting if you attend online or vote by proxy. Whether or not you plan to attend the annual meeting online, we encourage you to vote by proxy via the Internet, by telephone or by mail, as instructed below to ensure your vote is counted.

Beneficial Owners: Shares Registered in the Name of a Broker or Bank

If, on the record date, your shares were held in an account at a brokerage firm, bank, dealer or other similar organization, then you are the beneficial owner of shares held in “street name” and these proxy materials are being forwarded to you by that organization. The organization holding your account is considered the stockholder of record for purposes of voting at the annual meeting. As a beneficial owner, you have the right to direct your broker or other agent on how to vote the shares in your account. As discussed above, if you are a street name stockholder, you are invited to attend and vote your shares at the annual meeting online so long as you register to attend the Annual Meeting at www.proxydocs.com/GOSS by the Registration Deadline. However, since you are not the stockholder of record, you may not vote your shares online at the annual meeting unless you request and obtain a valid proxy from your broker, bank or other agent.

What am I voting on?

There are four proposals scheduled for a vote:

Proposal 1:To elect two directors to serve as Class III directors for a three-year term to expire at the 2024 annual meeting of stockholders.

Proposal 2:To consider and vote upon the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm for the year ending December 31, 2021.

Proposal 3:To consider and vote upon, on an advisory basis, the compensation of our named executive officers as disclosed in this proxy statement pursuant to the compensation disclosure rules of the SEC.

Proposal 4:To consider and vote upon, on an advisory basis, whether the stockholder vote to approve the compensation of the named executive officers as required by Section 14A(a)(2) of the Securities Exchange Act of 1934, as amended, should occur every one, two or three years.

How many votes do I have?

Each share of our common stock that you own as of April 19, 2021 entitles you to one vote.

How do I vote?

With respect to the election of directors, you may either vote “For” the nominees to the board of directors or you may “Withhold” your vote for any nominee you specify. With respect to the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm, you may vote “For,” “Against” or abstain from voting. With respect to the advisory vote on the compensation of our named executive officers, you may vote “For” or “Against” or abstain from voting. With respect to the advisory vote on whether the stockholder vote to approve the compensation of our named executive officers should occur every one, two or three years, you may vote for “one year,” “two years” or “three years” or abstain from voting.

Stockholders of Record: Shares Registered in Your Name

If you are a stockholder of record, there are several ways for you to vote your shares. Whether or not you plan to attend the virtual annual meeting, we urge you to vote by proxy prior to the annual meeting to ensure that your vote is counted.

•Via the Internet: You may vote at www.proxypush.com/GOSS 24 hours a day, seven days a week, by following the instructions provided in the Notice of Internet Availability of Proxy Materials. Votes submitted via the Internet must be received by 8:59 a.m., Pacific Time, on June 9, 2021.

•By Telephone: If you request printed copies of the proxy materials by mail, you may vote using a touch-tone telephone by calling (866) 230-8457, 24 hours a day, seven days a week.

•At the Virtual Annual Meeting: You may vote during the virtual annual meeting through www.proxydocs.com/GOSS. To be admitted to the annual meeting and vote your shares, you must register to attend the annual meeting at www.proxydocs.com/GOSS by the Registration Deadline at 8:00 p.m. Eastern Time on June 8, 2021, and provide the Control Number shown on your proxy card. After completion of your registration by the Registration Deadline, further instructions, including a unique link to access the annual meeting, will be emailed to you.

Beneficial Owners: Shares Registered in the Name of a Broker, Bank, or Other Agent

If you are a beneficial owner of shares registered in the name of your broker, bank or other agent, you should have received voting instructions from that organization rather than directly from us. Please check with your bank, broker, or other agent and follow the voting instructions they provide to vote your shares. Generally, you have three options for returning your proxy.

•By Method Listed on Voting Instruction Card: Please refer to your voting instruction card or other information provided by your bank, broker or other agent to determine whether you may vote by telephone or electronically on the Internet, and follow the instructions on the voting instruction card or other information provided by your broker, bank or other agent. A large number of banks and brokerage firms offer Internet and telephone voting. If your bank, broker or other agent does not offer Internet or telephone voting information, please follow the other voting instructions they provide to vote your shares.

•By Mail: You may vote by signing, dating and returning your voting instruction card in the pre-addressed envelope provided by your broker, bank or other agent.

•At the Virtual Annual Meeting: To vote online during the virtual annual meeting, you must obtain a valid proxy from your broker, bank or other agent. Follow the instructions from your broker, bank or other agent included with these proxy materials, or contact your broker or bank to request the proxy form authorizing you to vote the shares. You must also register to attend the annual meeting at www.proxydocs.com/GOSS by the Registration Deadline and provide the Control Number shown on your proxy card. After completion of your registration by the Registration Deadline, further instructions, including a unique link to access the annual meeting, will be emailed to you.

May I revoke my proxy?

If you give us your proxy, you may revoke it at any time before it is exercised. You may revoke your proxy in any one of the following ways:

•you may send in another signed proxy with a later date,

•you may authorize a proxy again on a later date on the Internet (only the latest Internet proxy submitted prior to the annual meeting will be counted),

•you may notify our corporate secretary, Christian Waage, at 3013 Science Park Road, San Diego, California 92121, in writing before the annual meeting that you have revoked your proxy, after which you are entitled to submit a new proxy or vote during the virtual annual meeting, or

•you may submit an electronic proxy during the annual meeting.

What constitutes a quorum?

The presence at the annual meeting, by virtual attendance or by proxy, of holders representing a majority of our outstanding common stock as of April 19, 2021, or 37,954,854 shares, constitutes a quorum at the meeting, permitting us to conduct our business.

What vote is required to approve each proposal?

Proposal 1:Election of Directors. The two nominees who receive the most “For” votes (among votes properly cast at the annual meeting or by proxy) will be elected. Only votes “For” will affect the outcome.

Proposal 2:Ratification of Independent Registered Public Accounting Firm. The ratification of the appointment of Ernst & Young LLP must receive “For” votes from the holders of a majority in voting power of the votes cast affirmatively or negatively on the proposal. Only votes “For” or “Against” will affect the outcome.

Proposal 3:Approval of the Compensation of the Named Executive Officers. The approval of the compensation of the named executive officers must receive “For” votes from a majority of the voting power of the votes cast affirmatively or negatively on the proposal. Only votes “For” or “Against” will affect the outcome.

Proposal 4:Frequency of Stockholder Vote on Executive Compensation. The alternative which receives the most votes (among votes properly cast at the annual meeting or by proxy) will be the stockholders’ recommendation, on an advisory basis, of the frequency of the stockholder vote on executive compensation.

Voting results will be tabulated and certified by the inspector of election appointed for the annual meeting.

How will my shares be voted if I do not specify how they should be voted?

If you are a stockholder of record and you indicate when voting on the Internet or by telephone that you wish to vote as recommended by the board of directors, then your shares will be voted at the annual meeting in accordance with the board’s recommendation on all matters presented for a vote at the annual meeting. Similarly, if you sign and return a proxy card but do not indicate how you want to vote your shares for a particular proposal or for all of the proposals, then for any proposal for which you do not so indicate, your shares will be voted in accordance with the board’s recommendation.

If you are a beneficial owner of shares held in street name and do not provide the organization that holds your shares with specific voting instructions, then, the organization that holds your shares may generally vote your shares in their discretion on “routine” matters but cannot vote on “non-routine” matters. If the organization that holds your shares does not receive instructions from you on how to vote your shares on a non-routine matter, that organization will inform the inspector of election that it does not have the authority to vote on that matter with respect to your shares. This is generally referred to as a “broker non-vote.”

What is the effect of withheld votes, abstentions and broker non-votes?

Shares of common stock held by persons attending the virtual annual meeting but not voting, and shares represented by proxies that reflect withheld votes or abstentions as to a particular proposal, will be counted as present for purposes of determining the presence of a quorum. Abstentions are not an affirmative or negative vote on a proposal, so abstaining does not count as a vote cast and has no effect for purposes of determining whether our stockholders have ratified the appointment of Ernst & Young LLP, our independent registered public accounting firm, or whether our stockholders have approved the compensation of the named executive officers. The election of directors and advisory vote on the frequency of the stockholder vote on executive compensation are determined by a plurality of votes cast, so a “Withhold” vote will not be counted in determining the outcome of such proposals.

Shares represented by proxies that reflect a broker non-vote will be counted as present for purposes of determining whether a quorum exists. As discussed above, a broker non-vote occurs when an organization holding shares for a beneficial owner has not received instructions from the beneficial owner and does not have discretionary authority to vote the shares for certain non-routine matters. With regard to the election of directors, the advisory vote to approve the compensation of the named executive officers and the advisory vote regarding the frequency of the stockholder vote to approve the compensation of the named executive officers, which are considered non-routine matters, broker non-votes will not be counted as votes cast and will have no effect on the result of the vote. However, ratification of the appointment of Ernst & Young LLP is considered a routine matter on which a broker or other nominee has discretionary authority to vote. Accordingly, no broker non-votes will likely result from this proposal.

How does the board of directors recommend that I vote?

The board of directors recommends that you vote:

•“For” each of the nominees for election as director;

•“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 of the compensation of our named executive officers; and

•“For every one year” regarding the frequency of the stockholder vote to approve the compensation of the named executive officers.

If you vote via the Internet, by telephone, or sign and return the proxy card by mail but do not make specific choices, your shares, as permitted, will be voted as recommended by our board of directors. If any other matter is presented at the annual meeting, your proxy will vote in accordance with his or her best judgment. As of the date of this proxy statement, we know of no matters that needed to be acted on at the annual meeting, other than those discussed in this proxy statement.

Who is paying the costs of soliciting these proxies?

We will pay all of the costs of soliciting these proxies. Our directors, officers and other employees may solicit proxies in person or by mail, telephone, fax or email. We will not pay our directors, officers and other employees any additional compensation for these services. We will ask banks, brokers and other institutions, nominees and fiduciaries to forward these proxy materials to their principals and to obtain authority to execute proxies. We will then reimburse them for their expenses. Our costs for forwarding proxy materials will not be significant.

How do I obtain an Annual Report on Form 10-K?

If you would like a copy of our Annual Report on Form 10-K for the year ended December 31, 2020 that we filed with the SEC on February 26, 2021, we will send you one without charge. Please write to:

Gossamer Bio, Inc.

3013 Science Park Road

San Diego, CA 92121

Attn: Corporate Secretary

All of our SEC filings are also available free of charge in the “Investors—Filings” section of our website at www.gossamerbio.com.

How can I find out the results of the voting at the annual meeting?

Preliminary voting results will be announced at the annual meeting. Final voting results will be published in our current report on Form 8-K to be filed with the SEC within four business days after the annual meeting. If final voting results are not available to us in time to file a Form 8-K within four business days after the meeting, we intend to file a Form 8-K to publish preliminary results and, within four business days after the final results are known to us, file an additional Form 8-K to publish the final results.

PROPOSAL 1:

ELECTION OF DIRECTORS

Our board of directors is divided into three classes, with one class of our directors standing for election each year, generally for a three-year term. Directors for each class are elected at the annual meeting of stockholders held in the year in which the term for their class expires and hold office until the third annual meeting following election and until such director’s successor is elected and qualified, or until such director’s earlier death, resignation or removal. As detailed in the section below, the composition of our board of directors is as follows: Class I consists of Kristina Burow and Thomas Daniel, M.D.; Class II consists of Joshua Bilenker, M.D. and Faheem Hasnain; and Class III consists of Russell Cox and Renée Galá.

At this meeting, two nominees for director are to be elected as Class III directors for a three-year term expiring at our 2024 annual meeting of stockholders and until their successors are duly elected and qualified. The nominees, who were recommended for nomination by our board of directors, are Russell Cox and Renée Galá. The Class I directors have one year remaining on their terms of office and the Class II directors have two years remaining on their terms of office.

If no contrary indication is made, proxies in the accompanying form are to be voted for Mr. Cox and Ms. Galá, or in the event that Mr. Cox or Ms. Galá is not a candidate or is unable to serve as a director at the time of the election (which is not currently expected), for any nominee who is designated by our board of directors to fill the vacancy. Each of Mr. Cox and Ms. Galá is currently a member of our board of directors.

All of our directors bring to the board of directors significant leadership experience derived from their professional experience and service as executives or board members of other corporations and/or private equity and venture capital firms. The process undertaken by the nominating and corporate governance committee in recommending qualified director candidates is described below under “Director Nomination Process.” Certain individual qualifications and skills of our directors that contribute to the board of directors’ effectiveness as a whole are described in the following paragraphs.

Board Independence

Our board of directors currently consists of six members. Our board of directors has determined that all of our directors, other than Mr. Hasnain, are independent directors in accordance with the listing requirements of the Nasdaq Global Select Market, or Nasdaq. The Nasdaq independence definition includes a series of objective tests, including that the director is not, and has not been for at least three years, one of our employees and that neither the director nor any of his family members has engaged in various types of business dealings with us. In addition, as required by Nasdaq rules, our board of directors has made a subjective determination as to each independent director that no relationships exist, which, in the opinion of our board of directors, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. In making these determinations, our board of directors reviewed and discussed information provided by the directors and us with regard to each director’s business and personal activities and relationships as they may relate to us and our management. There are no family relationships among any of our directors or executive officers.

Board Leadership Structure

Our board of directors is currently led by our Chairman and Chief Executive Officer, Faheem Hasnain, and our lead independent director, Thomas Daniel, M.D. Our board of directors recognizes that it is important to determine an optimal board leadership structure to ensure the independent oversight of management as the company continues to grow. The lead independent director is chosen by the independent members of the board of directors. We believe that this separation of responsibilities ensures the appropriate level of oversight, independence and responsibility is applied to all board decisions.

The duties of our lead independent director include the following:

•chairing meetings of the independent directors in executive session;

•facilitating communications between other members of our board and our chairman and chief executive officer;

•reviewing and approving matters, such as agenda items, schedule sufficiency, and, where appropriate, information provided to other board members;

•consulting with our chairman and chief executive officer on matters relating to corporate governance and board performance; and

•performing such other duties as the board may determine from time to time.

Our board of directors has concluded that our current leadership structure is appropriate at this time. However, our board of directors will continue to periodically review our leadership structure and may make such changes in the future as it deems appropriate.

Role of Board in Risk Oversight Process

Our board of directors has responsibility for the oversight of the company’s risk management processes and, either as a whole or through its committees, regularly discusses with management our major risk exposures, their potential impact on our business and the steps we take to manage them. The risk oversight process includes receiving regular reports from board committees and members of senior management to enable our board of directors to understand the company’s risk identification, risk management and risk mitigation strategies with respect to areas of potential material risk, including operations, finance, legal, regulatory, strategic and reputational risk.

The audit committee reviews information regarding liquidity and operations, and oversees our management of financial risks. Periodically, the audit committee reviews our policies with respect to risk assessment, risk management, loss prevention and regulatory compliance. Oversight by the audit committee includes direct communication with our external auditors, and discussions with management regarding significant risk exposures and the actions management has taken to limit, monitor or control such exposures. The compensation committee is responsible for assessing whether any of our compensation policies or programs has the potential to encourage excessive risk-taking. While each committee is responsible for evaluating certain risks and overseeing the management of such risks, the entire board of directors is regularly informed through committee reports about such risks. Matters of significant strategic risk are considered by our board of directors as a whole.

Board of Directors Meetings

During fiscal year 2020, our board of directors met twelve times, including telephonic meetings. In that year, each director attended at least 75% of the total number of meetings held during such director’s term of service by the board of directors and each committee of the board of directors on which such director served.

Board Committees and Independence

Our board of directors has established three standing committees—audit, compensation and nominating and corporate governance—each of which operates under a charter that has been approved by our board of directors.

Audit Committee

The audit committee’s main function is to oversee our accounting and financial reporting processes and the audits of our financial statements. This committee’s responsibilities include, among other things:

•appointing our independent registered public accounting firm;

•evaluating the qualifications, independence and performance of our independent registered public accounting firm;

•approving the audit and non-audit services to be performed by our independent registered public accounting firm;

•reviewing the design, implementation, adequacy and effectiveness of our internal accounting controls and our critical accounting policies;

•discussing with management and the independent registered public accounting firm the results of our annual audit and the review of our quarterly unaudited financial statements;

•reviewing, overseeing and monitoring the integrity of our consolidated financial statements and our compliance with legal and regulatory requirements as they relate to financial statements or accounting matters;

•reviewing on a periodic basis, or as appropriate, any investment policy and recommending to our board of directors any changes to such investment policy;

•reviewing with management and our auditors any earnings announcements and other public announcements regarding our results of operations;

•preparing the report that the SEC requires in our annual proxy statement;

•reviewing and approving any related party transactions and reviewing and monitoring compliance with our code of conduct and ethics; and

•reviewing and evaluating, at least annually, the performance of the audit committee and its members including compliance of the audit committee with its charter.

The members of our audit committee are Renée Galá, Joshua Bilenker, M.D. and Russell Cox. Ms. Galá serves as the chairperson of the committee. The audit committee met four times during fiscal year 2020. All members of our audit committee meet the requirements for financial literacy under the applicable rules and regulations of the SEC and Nasdaq. Our board of directors has determined that Ms. Galá is an “audit committee financial expert” as defined by applicable SEC rules and has the requisite financial sophistication as defined under the applicable Nasdaq rules and regulations. Our board of directors has determined each of Ms. Galá, Dr. Bilenker and Mr. Cox is independent under the applicable rules of the SEC and Nasdaq. The audit committee operates under a written charter that satisfies the applicable standards of the SEC and Nasdaq, which the audit committee will review and evaluate at least annually.

Both our external auditor and internal financial personnel meet privately with the audit committee and have unrestricted access to this committee.

Compensation Committee

The compensation committee approves policies relating to compensation and benefits of our officers and employees. The compensation committee approves corporate goals and objectives relevant to the compensation of our Chief Executive Officer and other executive officers, evaluates the performance of these officers in light of those goals and objectives and approves the compensation of these officers based on such evaluations. The compensation committee also approves the issuance of stock options and other awards under our equity plans. The compensation committee will review and evaluate, at least annually, the performance of the compensation committee and its members, including compliance by the compensation committee with its charter.

The members of our compensation committee are Russell Cox, Kristina Burow and Thomas Daniel, M.D. The compensation committee met six times during fiscal year 2020. Mr. Cox serves as the chairperson of the committee. Our board of directors has determined that each of Mr. Cox, Ms. Burow and Dr. Daniel is independent under the applicable rules and regulations of Nasdaq and is a “non-employee director” as defined in Rule 16b-3 promulgated under the Securities Exchange Act of 1934, as amended, or the Exchange Act. The compensation committee operates under a written charter, which the compensation committee will review and evaluate at least annually.

Nominating and Corporate Governance Committee

The nominating and corporate governance committee is responsible for assisting our board of directors in discharging the board’s responsibilities regarding the identification of qualified candidates to become board members, the selection of nominees for election as directors at our annual meetings of stockholders (or special meetings of stockholders at which directors are to be elected), and the selection of candidates to fill any vacancies on our board of directors and any committees thereof. In addition, the nominating and corporate governance committee is responsible for overseeing our corporate governance policies, reporting and making recommendations to our board of directors concerning governance matters and oversight of the evaluation of our board of directors.

The members of our nominating and corporate governance committee are Joshua Bilenker, M.D and Renée Galá. Dr. Bilenker serves as the chairperson of the committee. The nominating and corporate governance committee met one time during fiscal year 2020. Our board has determined that each of Dr. Bilenker and Ms. Galá is independent under the applicable rules and regulations of Nasdaq relating to nominating and corporate governance committee independence. The nominating and corporate governance committee operates under a written charter, which the nominating and corporate governance committee will review and evaluate at least annually.

Report of the Audit Committee of the Board of Directors

The audit committee oversees the company’s financial reporting process on behalf of our board of directors. Management has the primary responsibility for the financial statements and the reporting process, including the systems of internal controls. In fulfilling its oversight responsibilities, the audit committee reviewed and discussed the audited consolidated financial statements in the company’s annual report with management, including a discussion of any significant changes in the selection or application of accounting principles, the reasonableness of significant judgments, the clarity of disclosures in the financial statements and the effect of any new accounting initiatives.

The audit committee reviewed with Ernst & Young LLP, which is responsible for expressing an opinion on the conformity of the company’s audited consolidated financial statements with generally accepted accounting principles, its judgments as to the quality, not just the acceptability, of the company’s accounting principles and such other matters as are required to be discussed with the audit committee under generally accepted auditing standards and by the applicable requirements of the Public Company Accounting Oversight Board and the SEC. In addition, the audit committee has discussed with Ernst & Young LLP, its independence from management and the company, has received from Ernst & Young LLP the written disclosures and the letter required by applicable requirements of the Public Company Accounting Oversight Board regarding Ernst & Young LLP’s communications with the audit committee concerning independence, and has considered the compatibility of non-audit services with the auditors’ independence.

The audit committee met with Ernst & Young LLP to discuss the overall scope of its services, the results of its audit and reviews, and the overall quality of the company’s financial reporting. Ernst & Young LLP, as the company’s independent registered public accounting firm, also periodically updates the audit committee about new accounting developments and their potential impact on the company’s reporting. The audit committee’s meetings with Ernst & Young LLP were held with and without management present. The audit committee is not employed by the company, nor does it provide any expert assurance or professional certification regarding the company’s financial statements. The audit committee relies, without independent verification, on the accuracy and integrity of the information provided, and representations made, by management and the company’s independent registered public accounting firm.

In reliance on the reviews and discussions referred to above, the audit committee has recommended to the company’s board of directors that the audited consolidated financial statements be included in our Annual Report on Form 10-K for the year ended December 31, 2020. The audit committee and the company’s board of directors also have recommended, subject to stockholder approval, the ratification of the appointment of Ernst & Young LLP as the company’s independent registered public accounting firm for 2021.

This report of the audit committee is not “soliciting material,” shall not be deemed “filed” with the SEC and shall not be incorporated by reference by any general statement incorporating by reference this proxy statement into any filing under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended, whether made before or after the date hereof and irrespective of any general incorporation language in any such filing, except to the extent that we specifically incorporate this information by reference, and shall not otherwise be deemed filed under such acts.

The foregoing report has been furnished by the audit committee.


			Respectfully submitted,

			The Audit Committee of the Board of Directors
			Renée Galá (chairperson)
			Joshua Bilenker, M.D.
			Russell Cox

Compensation Committee Interlocks and Insider Participation

Russell Cox (chairperson), Kristina Burow and Thomas Daniel, M.D. served on our compensation committee during the 2020 fiscal year. None of the members of our compensation committee during the 2020 fiscal year has ever been one of our officers or employees. None of our executive officers currently serves, or has served, as a member of the board of directors or compensation committee of any entity that has one or more executive officers serving as a member of our board of directors or compensation committee other than Mr. Cox, who served as the Chief Executive Officer of Vital Therapies, Inc. from January 2018 until January 2019, for which Faheem Hasnain previously served on the compensation committee.

Director Nomination Process

Director Qualifications

Our nominating and corporate governance committee is responsible for reviewing with the board of directors, on an annual basis, the appropriate characteristics, skills and experience required for the board of directors as a whole and its individual members. In evaluating the suitability of individual candidates (both new candidates and current members), the board of directors, in approving (and, in the case of vacancies, appointing) such candidates, will take into account many factors, including the following:

•personal and professional integrity, ethics and values;

•experience in corporate management, such as serving as an officer or former officer of a publicly-held company;

•experience as a board member or executive officer of another publicly-held company;

•strong finance experience;

•diversity of expertise and experience in substantive matters pertaining to our business relative to other members of our board of directors;

•diversity of background and perspective, including, but not limited to, with respect to age, gender, race, place of residence and specialized experience;

•experience relevant to our business industry and with relevant social policy concerns; and

•relevant academic expertise or other proficiency in an area of our business operations.

Currently, our board of directors evaluates each individual in the context of the board of directors as a whole, with the objective of assembling a group that can best maximize the success of the business and represent stockholder interests through the exercise of sound judgment using its diversity of experience in these various areas.

Other than the foregoing, there are no stated minimum criteria for director nominees, although the nominating and corporate governance committee may also consider such other factors as it may deem to be in the best interests of our company and our stockholders. The nominating and corporate governance committee does, however, believe it appropriate for at least one, and preferably, several, members of our board of directors to meet the criteria for an “audit committee financial expert” as defined by SEC rules, and that a majority of the members of our board of directors meet the definition of “independent director” under Nasdaq qualification standards. The nominating and corporate governance committee also believes it is appropriate for our President and Chief Executive Officer to serve as a member of our board of directors.

Identification and Evaluation of Nominees for Directors

The nominating and corporate governance committee identifies nominees for director by first evaluating the current members of our board of directors willing to continue in service. Current members with qualifications and skills that are consistent with the nominating and corporate governance committee’s criteria for board of director service and who are willing to continue in service are considered for re-nomination, balancing the value of continuity of service by existing members of our board of directors with that of obtaining a new perspective or expertise.

If any member of our board of directors does not wish to continue in service or if our board of directors decides not to re-nominate a member for re-election or if the board of directors decides to expand the size of the board, the nominating and corporate governance committee identifies the desired skills and experience of a new nominee in light of the criteria above. The nominating and corporate governance committee generally polls our board of directors and members of management for their recommendations. The nominating and corporate governance committee may also review the composition and qualification of the boards of directors of our competitors, and may seek input from industry experts or analysts. The nominating and corporate governance committee reviews the qualifications, experience and background of the candidates. Final candidates are interviewed by the members of the nominating and corporate governance committee and by certain of our other independent directors and executive management. In making its determinations, the nominating and corporate governance committee evaluates each individual in the context of our board of directors as a whole, with the objective of assembling a group that can best contribute to the success of our company and represent stockholder interests through the exercise of sound business judgment. After review and deliberation of all feedback and data, the nominating and corporate governance committee makes its recommendation to our board of directors. Historically, the nominating and corporate governance committee has not relied on third-party search firms to identify director candidates. The nominating and corporate governance may in the future choose to do so in those situations where particular qualifications are required or where existing contacts are not sufficient to identify an appropriate candidate.

The nominating and corporate governance committee evaluates nominees recommended by stockholders in the same manner as it evaluates other nominees. We have not received director candidate recommendations from our stockholders, and we do not have a formal policy regarding consideration of such recommendations. However, any recommendations received from stockholders will be evaluated in the same manner that potential nominees suggested by members of our board of directors, management or other parties are evaluated.

Under our amended and restated bylaws, a stockholder wishing to suggest a candidate for director should write to our corporate secretary and provide such information about the stockholder and the proposed candidate as is set forth in our amended and restated bylaws and as would be required by SEC rules to be included in a proxy statement. In addition, the stockholder must include the consent of the candidate and describe any arrangements or undertakings between the stockholder and the candidate regarding the nomination. In order to give the nominating and corporate governance committee sufficient time to evaluate a recommended candidate and include the candidate in our proxy statement for the 2022 annual meeting, the recommendation should be received by our corporate secretary at our principal executive offices in accordance with our procedures detailed in the section below entitled “Stockholder Proposals.”

Director Attendance at Annual Meetings

Although we do not have a formal policy regarding attendance by members of our board of directors at our annual meeting, we encourage all of our directors to attend. Three of our directors attended our annual meeting of stockholders in 2020.

Communications with our Board of Directors

Stockholders seeking to communicate with our board of directors should submit their written comments to our corporate secretary, Gossamer Bio, Inc., 3013 Science Park Road, San Diego, CA 92121. The corporate secretary will forward such communications to each member of our board of directors; provided that, if in the opinion of our corporate secretary it would be inappropriate to send a particular stockholder communication to a specific director, such communication will only be sent to the remaining directors (subject to the remaining directors concurring with such opinion).

Prohibition Against Pledging and Hedging

We maintain an Insider Trading Compliance Policy that prohibits our officers, directors and employees pledging our stock as collateral to secure loans and from engaging in hedging transactions, including zero-cost collars and forward sale contracts. It further prohibits margin purchases of our stock, short sales of our stock, and any transactions in puts, calls or other derivative securities involving our stock.

Corporate Governance

Our company’s Code of Business Conduct and Ethics, Corporate Governance Guidelines, Audit Committee Charter, Compensation Committee Charter and Nominating and Corporate Governance Committee Charter are available, free of charge, on our website at www.gossamerbio.com. Please note, however, that the information contained on the website is not incorporated by reference in, or considered part of, this proxy statement. We will also provide copies of these documents as well as our company’s other corporate governance documents, free of charge, to any stockholder upon written request to Gossamer Bio, Inc., 3013 Science Park Road, San Diego, CA 92121.

Director Compensation

Our non-employee director compensation program provides for annual retainer fees and/or long-term equity awards for our non-employee directors. Each non-employee director receives an annual retainer of $40,000. Our lead independent director receives an additional annual retainer of $25,000. Non-employee directors serving as the chairs of the audit, compensation and nominating and corporate governance committees receive additional annual retainers of $15,000, $10,000 and $8,000, respectively. Non-employee directors serving as members of the audit, compensation and nominating and corporate governance committees receive additional annual retainers of $7,500, $5,000 and $4,000, respectively. The non-employee directors will also receive initial grants of options to purchase 47,000 shares of our common stock, vesting monthly over three years, upon election to the board of directors, and thereafter annual grants of options to purchase 23,500 shares of our common stock, vesting on the first to occur of (1) the first anniversary of the grant date or (2) the next occurring annual meeting of our stockholders.

Compensation under our non-employee director compensation policy is subject to the annual limits on non-employee director compensation set forth in our 2019 Incentive Award Plan, or the 2019 Plan. As provided in the 2019 Plan, our board of directors or its authorized committee may make exceptions to this limit for individual non-employee directors in extraordinary circumstances, as the board of directors or its authorized committee may determine in its discretion, provided that the non-employee director receiving such additional compensation may not participate in the decision to award such compensation or in other compensation decisions involving non-employee directors.

We have reimbursed and will continue to reimburse all of our non-employee directors for their travel, lodging and other reasonable expenses incurred in attending meetings of our board of directors and committees of our board of directors.

The following table sets forth the compensation that we paid or awarded during the year ended December 31, 2020 to each of our non-employee directors who served on the board during 2020. Mr. Hasnain and Dr. Gujrathi are not included in the following table as they served as executive officers for a portion of 2020 and their compensation is included in the Summary Compensation Table in the “Executive Compensation and Other Information” section below. Mr. Hasnain served as a non-employee director during 2020 prior to assuming the role of President and Chief Executive Officer in November 2020, and his director compensation is reported in the Summary Compensation Table under the “All Other Compensation” column. Dr. Gujrathi did not receive any compensation for her service as a member of the board of directors during 2020.

(1)This column reflects the grant date fair value of the option awards granted to the non-employee directors in 2020. In accordance with SEC rules, this column reflects the aggregate fair value of the option awards granted to the non-employee directors during 2020 computed as of the grant date in accordance with Financial Accounting Standards, Standard Board Accounting Codification Topic 718 for stock-based compensation transactions (ASC 718). Assumptions used in the calculation of this amount are included in Note 9 to our consolidated financial statements included in our Annual Report on Form 10‑K for the year ended December 31, 2020, which was filed with the SEC on February 26, 2021. This amount does not reflect the actual economic value that will be realized by the non-employee directors upon the vesting or exercise of the awards or the sale of the common stock underlying such awards.

The aggregate number of shares subject to stock options outstanding at December 31, 2020 for each non-employee director was as follows:


Name						Number of Securities Underlying Options Outstanding at December 31, 2020
Joshua Bilenker, M.D.						93,666
Kristina Burow						47,000
Russell Cox						93,666
Thomas Daniel, M.D.						178,111
Renée Galá						93,666

Stock Ownership Guidelines

In February 2020, following the recommendation of the nominating and corporate governance committee, our board of directors adopted a Stock Ownership Guidelines Policy. The purpose of the guidelines is to encourage ownership of our common stock, promote the alignment of the long-term interests of our executives and directors with the long-term interests of our company’s stockholders, and further promote our commitment to sound corporate governance. Under the guidelines, the target stock ownership level for our non-executive directors is 3x their aggregate annual cash retainer. Under these guidelines, the compliance deadline for all of our current directors is February 2024, although we expect that the target stock ownership levels likely will be achieved much sooner than that. Please see the description of our stock ownership guidelines for our executives under the “Executive Compensation and Other Information—Compensation Discussion and Analysis” section below.

Vote Required; Recommendation of the Board of Directors

If a quorum is present and voting at the annual meeting, directors shall be elected by a plurality of votes cast, meaning that the two nominees receiving the highest number of shares voted “For” their election will be elected to our board of directors. Votes withheld from any nominee, abstention and broker non-votes will be counted only for purposes of determining a quorum and are not considered votes cast for the foregoing purpose. Broker non-votes will have no effect on this proposal as brokers or other nominees are not entitled to vote on such proposals in the absence of voting instructions from the beneficial owner.

OUR BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS VOTE “FOR” THE ELECTION OF RUSSELL COX AND RENÉE GALÁ PROXIES SOLICITED BY THE BOARD OF DIRECTORS WILL BE SO VOTED UNLESS STOCKHOLDERS SPECIFY OTHERWISE.

PROPOSAL 2:

RATIFICATION OF SELECTION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The audit committee has selected Ernst & Young LLP as the company’s independent registered public accounting firm for the year ending December 31, 2021 and has further directed that management submit the selection of independent registered public accounting firm for ratification by the stockholders at the annual meeting. Ernst & Young LLP has audited the company’s financial statements since 2018. Representatives of Ernst & Young LLP are expected to be present at the annual meeting, will have an opportunity to make a statement if they so desire, and will be available to respond to appropriate questions.

Stockholder ratification of the selection of Ernst & Young LLP as the company’s independent registered public accounting firm is not required by Delaware law, the company’s amended and restated certificate of incorporation, or the company’s amended and restated bylaws. However, the audit committee 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, the audit committee will reconsider whether to retain that firm. Even if the selection is ratified, the audit committee in its discretion may direct the appointment of different independent registered accounting firm at any time during the year if the audit committee determines that such a change would be in the best interests of the company and its stockholders.

Independent Registered Public Accounting Firm’s Fees

The following table represents aggregate fees billed to us for services related to the fiscal years ended December 31, 2020 and 2019, by Ernst & Young LLP, our independent registered public accounting firm.


	Year Ended December 31,

Audit Fees(1)	$	789,312	$	383,922
Audit-Related Fees	—		—
Tax Fees(2)	18,025		99,329
All Other Fees(3)	18,450		18,805
Total	$	825,787	$	502,056

____________________

(1)Consists of audit fees billed for professional services performed by Ernst & Young LLP for the audit of our annual financial statements, the review of our registration statements on Form S-1 and S-3, the quarterly review of our financial statements, and related services that are normally provided in connection with statutory and regulatory filings or engagements.

(2)Tax Fees consist of fees for professional services, including tax consulting and compliance performed by Ernst & Young LLP.

(3)All Other Fees consist of consulting services.

The audit committee has considered whether the provision of non-audit services is compatible with maintaining the independence of Ernst & Young LLP, and has concluded that the provision of such services is compatible with maintaining the independence of our auditors.

Pre-Approval Policies and Procedures

Our audit committee has established a policy that all audit and permissible non-audit services provided by our independent registered public accounting firm will be pre-approved by the audit committee. All such services during the fiscal year ended December 31, 2020 were either pre-approved in accordance with this policy or pre-approved by our board of directors as the audit committee was newly formed in connection with our initial public offering and the responsibilities of the audit committee were, up to that point, handled by the board of directors. These services may include audit services, audit-related services, tax services and other services. The audit committee considers whether the provision of each non-audit service is compatible with maintaining the independence of our auditors. Pre-approval is detailed as to the particular service or category of services and is generally subject to a specific budget. Our independent registered public accounting firm and management are required to periodically report to the audit committee regarding the extent of services provided by the independent registered public accounting firm in accordance with this pre-approval, and the fees for the services performed to date.

Vote Required; Recommendation of the Board of Directors

The affirmative vote of the holders of a majority in voting power of the votes cast affirmatively or negatively on the proposal will be required to ratify the selection of Ernst & Young LLP, meaning the number of shares voted “For” the proposal must exceed the number of shares voted “Against” the proposal. Abstentions will not be counted toward the tabulation of votes cast on this proposal and will have no effect on the proposal. The approval of Proposal 2 is a routine proposal on which a broker or other nominee has discretionary authority to vote. Accordingly, no broker non-votes will likely result from this proposal.

OUR BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS VOTE “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. PROXIES SOLICITED BY THE BOARD OF DIRECTORS WILL BE SO VOTED UNLESS STOCKHOLDERS SPECIFY OTHERWISE.

PROPOSAL 3:

APPROVAL OF THE COMPENSATION OF THE NAMED EXECUTIVE OFFICERS

Under the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, or the Dodd-Frank Act, our stockholders are entitled to vote at the annual meeting to provide advisory approval of the compensation of our named executive officers as disclosed in this proxy statement pursuant to the compensation disclosure rules of the SEC. Pursuant to the Dodd-Frank Act, the stockholder vote on executive compensation is an advisory vote only, and it is not binding on us or our board of directors.

Although the vote is non-binding, our compensation committee and board of directors value the opinions of the stockholders and will consider the outcome of the vote when making future compensation decisions. As described more fully in the “Executive Compensation and Other Information” section of this proxy statement, our executive compensation program is designed to attract, retain and motivate individuals with superior ability, experience and leadership capability to deliver on our annual and long-term business objectives necessary to create stockholder value. We urge stockholders to read the “Executive Compensation and Other Information” section of this proxy statement, which describes in detail how our executive compensation policies and procedures operate and are intended to operate in the future. The compensation committee and the board of directors believe that our executive compensation program fulfills these goals and is reasonable, competitive and aligned with our performance and the performance of our executives.

We are asking our stockholders to indicate their support for our named executive officer compensation as described in this proxy statement. This proposal, commonly known as a “say-on-pay” proposal, gives our stockholders the opportunity to express their views on our named executive officers’ compensation. This vote is not intended to address any specific item of compensation, but rather the overall compensation of our named executive officers and the philosophy, policies and practices described in this proxy statement. Accordingly, we ask that our stockholders vote “FOR” the following resolution:

“RESOLVED, that Gossamer Bio, Inc.’s stockholders approve, on an advisory basis, the compensation of the named executive officers, as disclosed in Gossamer Bio, Inc.’s Proxy Statement for the 2021 Annual Meeting.”

Vote Required; Recommendation of the Board of Directors

The affirmative vote of a majority of the voting power of the votes cast affirmatively or negatively on the proposal will be required to approve the advisory vote regarding the compensation of the named executive officers. Abstentions will not be counted toward the tabulation of votes cast on this proposal and will have no effect on the proposal. Broker non-votes will have no effect on this proposal as brokers or other nominees are not entitled to vote on such proposal in the absence of voting instructions from the beneficial owner.

OUR BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS VOTE “FOR” THE APPROVAL OF THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS AS DISCLOSED IN THIS PROXY STATEMENT PURSUANT TO THE COMPENSATION DISCLOSURE RULES OF THE SEC.

PROPOSAL 4:

FREQUENCY OF STOCKHOLDER VOTE ON EXECUTIVE COMPENSATION

Under the Dodd-Frank Act, our stockholders are entitled to vote at the annual meeting regarding whether the stockholder vote to approve the compensation of our named executive officers as required by Section 14A(a)(2) of the Exchange Act (and as described in Proposal 3 of this proxy statement), should occur every one, two or three years. Under the rules issued by the SEC, stockholders shall also have the option to abstain from voting on the matter. Pursuant to the Dodd-Frank Act, the stockholder vote on the frequency of the stockholder vote to approve executive compensation is an advisory vote only, and it is not binding on us or our board of directors.

Although the vote is non-binding, our compensation committee and board of directors value the opinions of our stockholders and will consider the outcome of the vote when determining the frequency of the stockholder vote on executive compensation.

Vote Required; Recommendation of the Board of Directors

If a quorum is present and voting at the annual meeting, the alternative receiving the highest number of votes—every one year, every two years or every three years—will be the stockholders’ recommendation, on an advisory basis, of the frequency of the stockholder vote on executive compensation. Abstentions and broker non-votes will be counted only for purposes of determining a quorum. Broker non-votes will have no effect on this proposal as brokers or other nominees are not entitled to vote on such proposal in the absence of voting instructions from the beneficial owner.

OUR BOARD OF DIRECTORS RECOMMENDS A VOTE FOR EVERY ONE YEAR REGARDING THE FREQUENCY OF THE STOCKHOLDER VOTE TO APPROVE THE COMPENSATION OF THE NAMED EXECUTIVE OFFICERS AS REQUIRED BY SECTION 14A(A)(2) OF THE EXCHANGE ACT. PLEASE NOTE: STOCKHOLDERS ARE NOT VOTING TO APPROVE OR DISAPPROVE OUR BOARD’S RECOMMENDATION REGARDING THIS PROPOSAL 4.

SECURITY OWNERSHIP OF CERTAIN

BENEFICIAL OWNERS AND MANAGEMENT

The following table sets forth information relating to the beneficial ownership of our common stock as of April 19, 2021, by:

•each of our named executive officers;

•each of our directors;

•all directors and executive officers as a group; and

The number of shares beneficially owned by each stockholder is determined under rules issued by the SEC. Under these rules, beneficial ownership includes any shares as to which a person has sole or shared voting power or investment power. Applicable percentage ownership is based on 75,909,708 shares of common stock outstanding on April 19, 2021. In computing the number of shares beneficially owned by a person and the percentage ownership of that person, shares of common stock subject to options or other rights held by such person that are currently exercisable or will become exercisable within 60 days of April 19, 2021 are considered outstanding, although these shares are not considered outstanding for purposes of computing the percentage ownership of any other person.

Unless otherwise indicated, the address of each beneficial owner listed below is c/o Gossamer Bio, Inc., 3013 Science Park Road, San Diego, California 92121. We believe, based on information provided to us, that each of the stockholders listed below has sole voting and investment power with respect to the shares beneficially owned by the stockholder unless noted otherwise, subject to community property laws where applicable.

This compensation discussion and analysis provides an overview of our executive compensation philosophy, the overall objectives of our executive compensation program, and each compensation component that we provide. In addition, we explain how and why the compensation committee and our board of directors arrived at specific compensation policies and decisions involving our executive officers during the fiscal year ended December 31, 2020.

2020 Business Highlights

•Completed and reported top-line results for four randomized clinical trials of our clinical product candidates in patients, including two large Phase 2 trials of GB001 and Phase 1b studies of seralutinib, or GB002, and GB004.

•Initiated two proof-of-concept Phase 2 trials: the TORREY Phase 2 study of seralutinib in patients with PAH and the SHIFT-UC study of GB004 in patients with ulcerative colitis.

•Completed the dose-escalation portion of our study of GB1275 in patients with various selected tumor types and initiated enrollment of two Phase 1 expansion cohorts at the recommended Phase 2 dose.

•Nominated two pre-clinical product candidates for further evaluation ahead of potential first-in-human studies in the next 12-18 months.

•Closed equity and convertible offerings totaling $325 million of gross proceeds to help extend our cash runway into the second half of 2023.

Overview of 2020 Executive Compensation Decisions

In general, the majority of our named executive officers’ total compensation is tied directly to corporate and individual performance, increases in our stock price, or both. Specific elements of our executive compensation program that demonstrate our pay-for-performance philosophy include:

•The performance measures in our short-term cash incentive program are linked to key corporate objectives.

•Corporate achievement represents 100% of our chief executive officer’s annual bonus opportunity and 70% of our other named executive officer’s annual bonus opportunity.

•Our long-term equity incentives are provided to our named executive officers in the form of stock options and, commencing in 2020, restricted stock units, or RSUs, which vest over multi-year periods.

The primary elements of our total direct compensation program for the named executive officers and a summary of the actions taken by the compensation committee during 2020 are set forth below.


Market-Based Base Salary Increases for NEOs						•Our named executive officers received base salary increases for 2020 consistent with our pay positioning philosophy of targeting target total cash compensation at the 50th percentile of similarly situated executives at comparable companies based on our peer group.
Annual Cash Incentives Paid 100% Based on Corporate Performance						•Our corporate objectives for purposes of our annual cash incentives were established before the onset of the COVID-19 pandemic and were not adjusted by our compensation committee to take into account the impact of the pandemic. •Based on our achievement of our corporate performance goals during 2020 despite the difficult environment created by the COVID-19 pandemic, our named executive officers’ annual incentives tied to corporate performance were paid out at 105% of target.
Long-Term Incentive Compensation in Form of Stock Options and RSUs Vesting Over Multi-Year Periods						•Our named executive officers received stock options which vest over four years and, commencing in 2020, RSUs, which vest over three years. ◦Stock options are an important vehicle for tying executive pay to performance, because they deliver future value only if the value of our common stock increases above the exercise price. As a result, they provide strong incentives for our executive officers to increase the value of our common stock over the long term, and they tightly align the interests of our executives with those of our stockholders. ◦RSU awards are granted because they are less dilutive to our stockholders, as fewer shares of our common stock are granted to achieve an equivalent value relative to stock options, and because RSU awards are an effective retention tool that maintain value even in cases where the share price is trading lower than the initial grant price.

Our Executive Compensation Practices

We endeavor to maintain sound executive compensation policies and practices consistent with our executive compensation philosophy. The following table highlights some of our executive compensation policies and practices, which are structured to drive performance and align our executives’ interests with our stockholders’ long-term interests:

OUR EXECUTIVE COMPENSATION BEST PRACTICES

Pay for Performance. We design our executive compensation program to align pay with company performance.

No Special Health or Welfare Benefits for Executives. Our executive officers participate in broad-based, company-sponsored health and welfare benefits programs on the same basis as our other full-time, salaried employees.

Significant Portion of Compensation is at Risk. Under our executive compensation program, a significant portion of compensation is “at risk” based on our performance to align the interests of our executive officers and stockholders

No Post-Employment Tax Gross-Ups. We do not provide any post-employment tax reimbursement payments (including “gross-ups”) on any severance or change-in-control payments or benefits

Independent Compensation Committee and Compensation Advisor. The compensation committee is comprised solely of independent directors. The compensation committee engages its own compensation consultant to assist with making compensation decisions.

Prohibition on Hedging and Pledging. Our insider trading policy prohibits our employees (including executive officers) and directors from engaging in hedging or short-term speculative transactions involving our securities.

Stock Ownership Guidelines for Directors and Executive Officers. We maintain stock ownership guidelines for our directors and executive officers to encourage ownership of our common stock and alignment with the long-term interests of our stockholders

“Double Trigger” Change in Control Benefits. The employment letters with our named executive officers do not include any “single trigger” change in control severance benefits

Competitive Peer Group. Our compensation committee selects our peers from biotechnology and pharmaceutical companies that are similar to us with respect to market capitalization, headcount and commercialization stage.

Annual Market Review of Executive Compensation. The compensation committee and its compensation consultant annually assess competitiveness and market alignment of our compensation plans and practices.

Multi-Year Vesting Requirements for Equity Awards. The equity awards granted to our executive officers vest over multi-year periods, consistent with current market practice and our retention objectives

Minimize Inappropriate Risk Taking. Our compensation program is weighted toward long-term incentive compensation to discourage short-term risk taking, and it includes multiple performance measures and caps on short-term incentive compensation.

Compensation Philosophy and Objectives

We recognize that the ability to excel depends on the integrity, knowledge, imagination, skill, diversity and teamwork of our employees. To this end, the key objectives of our executive compensation program are:

•To attract, engage and retain an executive team who will provide leadership for our future success by providing competitive total pay opportunities.

•To establish a direct link between our business results, individual executive performance and total executive compensation.

•To align the interests of our executive officers with those of our stockholders.

Compensation Determination Process

Role of the compensation committee

The compensation committee of our board of directors develops, reviews and approves each of the elements of our executive compensation program. The compensation committee also regularly assesses the effectiveness and competitiveness of our compensation programs.

In the first quarter of each year, the compensation committee reviews the performance of each of our named executive officers during the previous year. At this time the compensation committee also reviews our performance relative to the corporate performance objectives set by the board of directors for the year under review and makes the final bonus payment determinations based on our overall corporate performance and the compensation committee’s evaluation of each named executive officer’s performance for the year under review. In connection with this review, the compensation committee also reviews and adjusts, as appropriate, annual base salaries for our named executive officers and grants, as appropriate, additional equity awards to our named executive officers and certain other eligible employees.

During the fourth quarter of each year our compensation committee also reviews the corporate performance objectives for purposes of our performance bonus programs for the following year, but such objectives historically have been recommended to the full board of directors for approval.

Role of Our Executive Officers

Our Chief Executive Officer, with the assistance and support of our General Counsel and our human resources department, aids the compensation committee by providing annual recommendations regarding the compensation of our other named executive officers. The compensation committee also, on occasion, meets with our Chief Executive Officer to obtain recommendations with respect to our compensation programs and practices generally. The compensation committee considers, but is not bound to accept, the Chief Executive Officer’s recommendations with respect to named executive officer compensation.

Our Chief Executive Officer generally attends all of the compensation committee meetings, but the compensation committee also holds executive sessions that are not attended by any members of management or non-independent directors, as needed from time to time. Any deliberations or decisions regarding our Chief Executive Officer’s compensation are made without him present.

Role of Compensation Consultant and Comparable Company Information

The compensation committee is authorized to retain the services of third-party compensation consultants and other outside advisors, from time to time, to assist in its evaluation of executive compensation, including the authority to approve the consultant’s reasonable fees and other retention terms.

In 2020, the compensation committee again retained Radford, a business unit of AON plc, or Radford, an independent third-party compensation consulting firm for guidance in making compensation decisions. Specifically, for 2020, the compensation committee requested Radford to advise it on a variety of compensation-related issues, including:

•conducting an analysis of current practices of comparable public companies to assist the compensation committee in developing director and executive compensation levels;

•reviewing our peer group to determine whether additional or different peer companies or groups are necessary to provide appropriate information on market practices and compensation levels; and

•providing general information concerning director and executive compensation trends and developments.

Radford did not provide any other services to us in 2020 beyond its engagement as an advisor to the compensation committee on director and executive compensation matters. The compensation committee assessed the independence of Radford pursuant to SEC and Nasdaq rules and concluded that no conflict of interest existed that would have prevented Radford from serving as an independent consultant to the compensation committee currently or during 2020.

Competitive Positioning

The compensation committee reviews our peer group annually to reflect changes in market capitalization and other factors, including acquisitions, and revises the companies included in the peer group accordingly. For 2020, Radford assisted the compensation committee in identifying an appropriate peer group of companies for use as a reference when determining 2020 director and executive compensation. The peer group identified below and was selected in August 2019 for purposes of setting 2020 compensation and the selection criteria identified below were measured at such date.

The identified peer group consisted of 23 life sciences companies in similar phases of development as us with the following characteristics was selected based on the following parameters and not on the basis of executive compensation levels:


MARKET CAPITALIZATION						•Generally between $400M to $4B as of August 2019, representing a range of 0.3x to 3.0x our market capitalization at the time the peer group was established (approximately $1.3 billion). •Our market capitalization was positioned near the 50th percentile of the peers at the time the peer group was selected in August 2019.
SECTOR AND STAGE						•Public U.S. biopharma organizations focused on immunology/immuno-oncology, inflammation and autoimmune companies as well as companies with diverse asset portfolio, where possible. Ø Emphasis on Phase 1 to 3 companies to reflect our Phase 2 stage of development at the time the peer group was selected Ø Select group of early commercial companies included, where applicable Ø Focus on companies that went public in the last three to five years
HEADCOUNT						•Companies with generally between 50 and 400 employees based on Gossamer’s headcount of 118 employees in August 2019.
GEOGRAPHIC LOCATION						•Focused on companies located in Southern California and other biotech talent hubs such as San Francisco Bay Area, Seattle and Boston, where applicable.

For 2020, this peer group consisted of the following companies:


Acceleron Pharma			Epizyme

Aimmune Therapeutics			Fate Therapeutics

Alector			Global Blood Therapeutics

Allakos			Kiniksa Pharmaceuticals

Allogene Therapeutics			MyoKardia

AnaptysBio			NGM Biopharmaceuticals

Atara Biotherapeutics			Odonate Therapeutics

Biohaven Pharmaceutical			Principia Biopharma

Blueprint Medicines			Replimune Group

Deciphera Pharmaceuticals			Rubius Therapeutics

Denali Therapeutics			Tricida

Eidos Therapeutics

Our compensation committee reviewed the foregoing comparable company data in connection with its determinations of the 2020 base salaries, target bonuses and equity awards for our named executive officers. The compensation committee generally attempts to set base salaries at target total cash compensation levels at the 50th percentile of the peer company data for comparable positions and total annual equity award value at approximately the 62nd percentile. The compensation committee does not, however rely entirely on that data to determine named executive officer compensation. Instead, as described above and consistent with past practice, the compensation committee members rely on their judgment and experience in setting those compensation levels and making those awards. As a result, variations on this pay positioning occur from year to year.

We expect that the compensation committee will continue to review comparable company data in connection with setting the compensation we offer our named executive officers to help ensure that our compensation programs are competitive and fair.

The compensation levels of the named executive officers reflect to a significant degree the varying roles and responsibilities of such executives. As a result of the compensation committee’s and the board of director’s assessment of our Chief Executive Officer’s roles and responsibilities within our company, there are significant compensation differentials between these named executive officers and our other named executive officers.

Executive Compensation Components

The following describes each component of our executive compensation program, the rationale for each, and how compensation amounts are determined.

Base Salaries

In general, base salaries for our named executive officers are initially established through arm’s length negotiation at the time the executive is hired, taking into account such executive’s qualifications, experience and prior salary. Base salaries of our named executive officers are approved and reviewed annually by our compensation committee and adjustments to base salaries are based on the scope of an executive’s responsibilities, individual contribution, prior experience and sustained performance. This strategy is consistent with our intent of offering compensation that is cost-effective, competitive and contingent on the achievement of performance objectives.

In February 2020, the compensation committee reviewed the base salaries of our named executive officers. The compensation committee, in consultation with our Chief Executive Officer (with respect to the salaries of our other named executive officers) and its independent compensation consultant, determined that the base salaries of our named executive officers would be as follows, with increases effective March 1, 2020:


Named Executive Officer	2020 Base Salary	Percentage Increase from 2019
Mr. Hasnain	$572,000	N/A(1)
Dr. Gujrathi	$572,000	10	%
Mr. Giraudo	$420,000	5	%
Dr. Salter-Cid	$406,600	7	%
Mr. Waage	$401,700	3	%
Dr. Dupont	$440,000	3	%

____________________

(1) Mr. Hasnain’s 2020 annual base salary was established in November 2020 in connection with his commencement of service as our Chief Executive Officer.

The foregoing increases were designed to keep each executive’s annual base salary and target total cash compensation close to the 50th percentile of similarly situated executives, in line with our pay positioning philosophy. Based on the comparable market information provided to the compensation committee by Radford, for 2020, after the foregoing increases, the base salaries of our named executive officers generally approximated the 50th percentile of similarly situated executives among our peer group.

The actual base salaries paid to all of our named executive officers for 2020 are set forth in the “Summary Compensation Table” below.

Performance Bonuses

Each named executive officer is also eligible for a performance bonus based upon the achievement of certain corporate performance goals and objectives approved by our board of directors.

Bonuses are set based on the executives’ respective base salaries for the relevant bonus year, and are expected to be paid out in the first quarter of the following year. The target levels for executive bonuses for 2020 were as follows: 55% of base salary for Dr. Gujrathi and Mr. Hasnain, and 40% of base salary for our other named executive officers. The target cash incentive award for our chief executive officer was increased from the target level of 50% of base salary in effect in 2019. The target cash incentive awards of our other named executive officers as a percentage of base salary remained unchanged from 2019.

At the beginning of each year, the board of directors (considering the recommendations of the compensation committee and management) sets corporate goals and milestones for the year. These goals and milestones and the proportional emphasis placed on each are set by the board of directors after considering management input and our overall strategic objectives. These goals generally relate to factors such as clinical and regulatory development of our products, portfolio sustainability, business development and financial targets. The board of directors, upon recommendation of the compensation committee, determines the level of achievement of the corporate goals for each year.

All final bonus payments to our named executive officers are determined by our compensation committee. The actual bonuses awarded in any year, if any, may be more or less than the target, depending on individual performance and the achievement of corporate objectives and may also vary based on other factors at the discretion of the compensation committee (or the full board of directors, with respect to our Chief Executive Officer). Under our annual incentive plan, the maximum bonus payable to an executive is 150% of his or her target bonus.

All of our named executive officers’ annual bonus payouts are tied to performance relative to the corporate goals set by our board of directors.

Corporate Performance Goals

The corporate performance goals for 2020 were approved by the board of directors in February 2020. The 2020 performance goals were set prior to the onset of the COVID pandemic at levels such that the attainment of executive target annual cash incentive award opportunities was not assured at the time they were set and would require a high level of effort and execution on the part of the executive officers and others in order to achieve the goals. The board of directors also specified a “target exceeds” weighting for each corporate goal, corresponding to additional credit that could be achieved for each goal in the event of over performance in a given area, generally representing up to 150% of the target level for each goal.

To determine our corporate performance percentage for 2020, the compensation committee employed a holistic analysis that took into account both the extent to which the performance goals had been achieved or exceeded as well as the relative difficulty of achieving the goals that were met and that were only partially met. In light of our strong performance against the objectives set by the compensation committee in early 2020, especially related to the clinical and regulatory development of GB004, the compensation committee determined our corporate performance percentage to be 105% of the target performance level for 2020. The table below provides additional details about the corporate performance goals for 2020 and the compensation committee’s assessment of our actual performance against our 2020 corporate performance goals:


2020 CORPORATE GOAL	WEIGHTING	2020 ACHIEVEMENTS	PERFORMANCE	WEIGHTED PERFORMANCE
CLINICAL AND REGULATORY DEVELOPMENT
•GB001	20%	•Announced topline results from the Phase 2b LEDA study and Phase 2 TITAN study in October 2020	100%	20%
•Seralutinib	10%	•Presented clinical data from Phase 1b study in December 2020	100%	10%
•GB004	15%	•Announced topline results from Phase 1b study in May 2020, including safety and tolerability, pharmacokinetic profile and target engagement and encouraging trends in clinical activity	133%	20%
•GB1275	10%	•Completed dose escalation phase of the KEYNOTE-A36 Phase 1/2 study and announced early safety and biomarker data	100%	10%
RESEARCH AND DEVELOPMENT	35%	•Commenced Two Phase 2 proof-of-concept studies, the TORREY study in pulmonary arterial hypertension and the SHIFT-UC study in ulcerative colitis •Achieved preclinical drug candidate nomination for two preclinical research programs and lead optimization on three preclinical research programs	100%	35%
FINANCE	10%	•Ensured continued cash position sufficient into the second half of 2023	100%	10%
TOTAL				105%

This overall 105% achievement level was then used to determine each named executive officer’s bonus. Dr. Dupont resigned in May 2020 and did not receive a 2020 bonus. Mr. Hasnain’s annual bonus was prorated for the portion of the year during which he served as our President and Chief Executive Officer. The annual bonuses paid to our named executive officers for 2020 are set forth in the Summary Compensation Table below.

Long-Term Equity Incentives

The goals of our long-term, equity-based incentive awards are to align the interests of our named executive officers and other employees, non-employee directors and consultants with the interests of our stockholders. Because vesting is based on continued employment over multiple years, our equity-based incentives also encourage the retention of our named executive officers through the vesting period of the awards. In determining the size of the long-term equity incentives to be awarded to our named executive officers, we take into account a number of internal factors, such as the relative job scope, the value of existing long-term incentive awards, individual performance history, prior contributions to us, the size of prior grants as well as comparable company information, as described below. We have had no program, plan or practice pertaining to the timing of stock option grants to named executive officers coinciding with the release of material non-public information.

We use equity awards to compensate our named executive officers both in the form of initial grants in connection with the commencement of employment and annual refresher grants. Our compensation committee typically approves annual equity awards during the first quarter of each year. While we intend that the majority of stock awards to our employees be made pursuant to initial grants or our annual grant program, the compensation committee retains discretion to make equity awards to employees at other times, including in connection with the promotion of an employee, to reward an employee, for retention purposes or for other circumstances recommended by management or the compensation committee.

Equity Vehicles

Annual equity awards are granted under our 2019 Plan, using a mix of different equity instruments to further the goal of attracting and retaining top performers and to balance the relative advantages of different instruments.

•Stock options are an important vehicle for tying executive pay to performance, because they deliver future value only if the value of our common stock increases above the exercise price. As a result, they provide strong incentives for our executive officers to increase the value of our common stock over the long term, and they tightly align the interests of our executives with those of our stockholders.

•Commencing with the annual awards in 2020, RSU awards are granted because they are less dilutive to our stockholders, as fewer shares of our common stock are granted to achieve an equivalent value relative to stock options, and because RSU awards are an effective retention tool that maintain value even in cases where the share price is trading lower than the initial grant price.

The exercise price of each stock option grant is the fair market value of our common stock on the grant date, as determined by our board of directors from time to time. Option awards generally vest over a four-year period as follows: 25% of the shares underlying the option vest on the first anniversary of the date of the vesting commencement date and the remainder of the shares underlying the option vest in equal monthly installments over the remaining 36 months thereafter. RSU awards generally vest in three equal annual installments. From time to time, our compensation committee may, however, determine that a different vesting schedule is appropriate.

2020 Annual Equity Awards

Generally, the compensation committee determines the value of each executive officer’s annual equity grant using a holistic evaluation that takes into account a competitive market analysis prepared by our independent compensation consultant with market data for each role, the recommendations of our Chief Executive Officer based on his evaluation of their individual performance (except with respect to the Chief Executive Officer’s performance), the extent to which the executive officer is currently vested in his or her stock awards, scope and criticality of the executive’s role and parity in targets among executives in roles of a given level. For 2020, our compensation committee reviewed competitive market data prepared by Radford in connection with its grant of long-term equity incentive awards to the named executive officers and approved equity awards to our named executive officers intended to approximate the 62nd percentile of comparable company data for similar positions, which it considers appropriate to create a meaningful opportunity for reward predicated on the creation of long-term stockholder value.

In February 2020, the compensation committee approved the annual equity awards for our named executive officers in a combination of options and RSU awards with approximately 50% of the value allocated in the form of options and approximately 50% of the value allocated in the form of RSU awards. The equity awards granted to our named executive officers for 2020 are set forth in the “Grants of Plan-Based Awards Table” below, each of which vests over three or four years in accordance with the standard vesting schedules described above.

For a description of certain accelerated vesting provisions applicable to the stock awards granted to our named executive officers, see “Employment Letters with Our Named Executive Officers” below.

Stock Ownership Guidelines

In February 2020, following the recommendation of the nominating and corporate governance committee, our board of directors adopted a Stock Ownership Guidelines Policy. The purpose of the guidelines is to encourage ownership of our common stock, promote the alignment of the long-term interests of our Chief Executive Officer, other executives and directors with the long-term interests of our company’s stockholders, and further promote our commitment to sound corporate governance. Under the guidelines, the target common stock ownership level for our President and Chief Executive Officer is 3x his base annual salary, the target stock ownership level for our non-executive directors is 3x their aggregate annual cash retainer and the target stock ownership level for our other executive officers is 1x their base annual salary. Under these guidelines, the compliance deadline for all of our current executive officers and directors is February 2024, although we expect that the target stock ownership levels likely will be achieved much sooner than that.

Health, Welfare and Retirement Benefits

The establishment of competitive benefit packages for our employees is an important factor in attracting and retaining highly qualified personnel.

Health and Welfare Benefits

Our named executive officers are eligible to participate in our employee benefit plans, including our medical, dental, vision, group life, disability and accidental death and dismemberment insurance plans, in each case on the generally on same basis as all of our other employees. We believe that these health and welfare benefits help ensure that we have a productive and focused workforce through reliable and competitive health and other benefits.

Retirement Savings

We maintain a defined contribution employee retirement plan, or 401(k) plan, for our employees. Our named executive officers are eligible to participate in the 401(k) plan on the same basis as our other employees. The 401(k) plan is intended to qualify as a tax-qualified plan under Section 401(k) of the Code. The 401(k) plan provides that each participant may make pre-tax deferrals from his or her compensation up to the statutory limit, which is $19,000 for calendar year 2019, and other testing limits. Participants that are 50 years or older can also make “catch-up” contributions, which in calendar year 2019 may be up to an additional $6,000 above the statutory limit. The 401(k) plan provides for discretionary matching and profit sharing contributions, and we currently contribute up to a maximum of $4,000 per calendar year to the 401(k) plan for each of our employees, which vests over four years. Participant contributions are held and invested, pursuant to the participant’s instructions, by the plan’s trustee.

Other Benefits

Our board of directors may elect to adopt qualified or non-qualified benefit plans in the future if it determines that doing so is in our best interests. We generally do not provide perquisites or personal benefits to our named executive officers, except in limited circumstances.

Post Termination and Change in Control Benefits

Our named executive officers may become entitled to certain benefits or enhanced benefits in connection with a change in control of our company. The employment letters with each of our named executive officers provide for accelerated vesting of all outstanding equity awards, as well as certain other benefits, upon a qualifying termination in connection with a change in control of our company. For additional discussion, please see “Employment Letters with Our Named Executive Officers” below.

Prohibition on Certain Transactions in Gossamer Bio Securities

Our insider trading policy prohibits officers, directors and employees, and entities controlled by such individuals and members of their households, from making short sales in our equity securities, transacting in puts, calls or other derivative securities involving our equity securities, on an exchange or in any other organized market, engaging in hedging or monetization transactions, such as zero-cost collars and forward sale contracts, purchasing our securities on margin or pledging our securities as collateral for a loan.

Tax and accounting considerations

Deductibility of Executive Compensation

The compensation committee and our board of directors have considered the potential future effects of Section 162(m) of the Internal Revenue Code on the compensation paid to our executive officers. Section 162(m) disallows a tax deduction for any publicly held corporation for individual compensation exceeding $1.0 million in any taxable year for “covered employees.” While we consider the tax deductibility of each element of executive compensation as a factor in our overall compensation program, the compensation committee, however, retains the discretion to approve compensation that may not qualify for the compensation deduction if, considering all applicable circumstances, it would be in our best interest for such compensation to be paid without regard to whether it may be tax deductible.

Accounting for Stock-Based Compensation

Under FASB ASC 718, we are required to estimate the grant date “fair value” for each grant of equity award using various assumptions. This calculation is performed for accounting purposes and reported in the compensation tables below, even though recipients may never realize any value from their awards. ASC 718 also requires us to recognize the compensation cost of stock-based awards in our income statements over the period that an employee is required to render service in exchange for the award.

Risk Assessment of Compensation Program

In February 2021, management assessed our compensation program for the purpose of reviewing and considering any risks presented by our compensation policies and practices that are reasonably likely to have a material adverse effect on us. As part of that assessment, management reviewed the primary elements of our compensation program, including base salary, short-term incentive compensation and long-term incentive compensation. Management’s risk assessment included a review of the overall design of each primary element of our compensation program, and an analysis of the various design features, controls and approval rights in place with respect to compensation paid to management and other employees that mitigate potential risks to us that could arise from our compensation program. Following the assessment, management determined that our compensation policies and practices did not create risks that were reasonably likely to have a material adverse effect on us and reported the results of the assessment to our compensation committee.

Report of the Compensation Committee of the Board of Directors

The compensation committee of our board of directors has submitted the following report for inclusion in this proxy statement:

The compensation committee has reviewed and discussed with management the Compensation Discussion and Analysis set forth above. Based on such review and discussions, the compensation committee has recommended to the board of directors that the Compensation Discussion and Analysis be included in this proxy statement and in the Annual Report on Form 10-K for the year ended December 31, 2020, filed by us with the SEC.

This report of the compensation committee is not “soliciting material,” shall not be deemed “filed” with the SEC and shall not be incorporated by reference by any general statement incorporating by reference this proxy statement into any filing under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended, whether made before or after the date hereof and irrespective of any general incorporation language in any such filing, except to the extent that we specifically incorporate this information by reference, and shall not otherwise be deemed filed under such acts.

The foregoing report has been furnished by the compensation committee.

Respectfully submitted,

The Compensation Committee of the Board of Directors

Russell J. Cox (Chairman)

Kristina Burow

Thomas Daniel, M.D.

(3)Other than the option award granted to Mr. Hasnain, the option awards vest with respect to 25% of the underlying shares on the first anniversary of the grant date, and with respect to the balance of the shares in consecutive equal monthly installments on the last day of each month thereafter for 36 months, subject to continuous service through each vesting date. All option awards have a 10-year term from the grant date.

The option award granted to Mr. Hasnain was granted in connection with his service as Chairman of the Board in accordance with our policy for non-employee members of the board. The options become fully vested on the first to occur of (a) the first anniversary of the grant date or (b) the next occurring annual meeting of the Issuer's stockholders. In addition, the options will vest in full upon a change in control pursuant to the terms of the non-employee director compensation program, as described above under “Director Compensation.”

For a description of the accelerated vesting applicable to the foregoing equity awards, see “Employment Letters with Our Named Executive Officers” below.

(4)The applicable grant-date fair value of each option and RSU award was calculated in accordance with ASC 718. For a discussion of our valuation methodology used, see Note 9 to our consolidated financial statements for the year-end December 31, 2020 included in our Annual Report on Form 10-K filed with the SEC on February 26, 2021. These amounts do not reflect whether the recipient has actually realized or will realize. Whether, and to what extent, a named executive officer realizes a financial benefit from the awards will depend on our actual operating performance, stock price fluctuations and the named executive officer’s continued service to us.

Employment Letters with Named Executive Officers

Employment Arrangements with Mr. Hasnain

In connection with Mr. Hasnain’s appointment as our President and Chief Executive Officer, we entered into a letter agreement with him on November 16, 2020, which sets forth the terms of his appointment as President and Chief Executive Officer. Under the terms of the employment letter agreement with Mr. Hasnain, Mr. Hasnain’s annual base salary is $572,000, and his target annual bonus is 55% of his base salary.

Pursuant to the employment letter agreement with Mr. Hasnain, if we terminate his employment other than for cause (as defined below) or Mr. Hasnain terminates his employment for good reason (as defined below), and other than as a result of death or disability, in either case prior to a change in control (as defined below) or more than 12 months following a change in control, he is entitled to the following payments and benefits, subject to the timely execution and non-revocation of a general release of claims in our favor: (1) continued payment of his base salary at the then-current rate for 12 months, paid in accordance to our payroll practices; (2) a payment equal to his then current target annual bonus opportunity, pro-rated for the portion of the current calendar year in which he was employed, payable in a lump sum payment 60 days following the date of termination; (3) payment of the full premium for continued health plan coverage for up to 12 months following the date of termination or, if earlier, up to the date he becomes eligible to receive equivalent or increased health plan coverage by means of subsequent employment or self-employment; and (4) automatic acceleration of the vesting and exercisability of his unvested stock awards, as to the number of stock awards that would vest over the 12-month period following the date of termination. The cash severance benefits described in clause (1) above shall be paid or commence on the first payroll period following the date his release becomes effective and the first payment shall include all accrued amounts from the date of termination, provided that if the period during which he may deliver the release spans two calendar years, the initial payment date shall be no earlier than January 1 of the second calendar year.

If Mr. Hasnain’s employment is terminated by us other than for cause or by Mr. Hasnain for good reason, in each case within 12 months after a change in control, in lieu of the severance benefits described above, he is entitled to the following payments and benefits, subject to the timely execution and non-revocation of a general release of claims in our favor: (1) continued payment of his base salary at the then-current rate for 18 months, paid in accordance to our payroll practices; (2) a payment equal to his then current target annual bonus opportunity, payable in a lump sum payment 60 days following the date of termination; (3) payment of the full premium for continued health plan coverage for up to 18 months following the date of termination or, if earlier, up to the date he becomes eligible to receive equivalent or increased health plan coverage by means of subsequent employment or self-employment; and (4) automatic full vesting and exercisability of his unvested stock awards. The cash severance benefits described in clause (1) above shall be paid or commence on the first payroll period following the date the executive’s release becomes effective and the first payment shall include all accrued amounts from the date of termination, provided that if the period during which executive may deliver the release spans two calendar years, the initial payment date shall be no earlier than January 1 of the second calendar year.

In addition, in the event of Mr. Hasnain’s termination of employment by reason of his death or disability, and subject to the timely execution and non-revocation of a general release of claims in our favor by the executive, then the greater of (1) 50% of the unvested portion of any equity awards then held by him immediately prior to such termination, and (2) the portion of such equity awards that would have otherwise vested in the 12 month period following the date of such termination of employment, will vest and will no longer be subject to restrictions or forfeiture on the date of such termination.

If Mr. Hasnain’s employment as President and Chief Executive Officer terminates without cause or by him for good reason, but he continues to serve as Chairman or Executive Chairman of the Board, his equity awards will not accelerate as described above but will continue to vest in accordance with their original terms.

In the event we terminate Mr. Hasnain’s employment for any reason, including for cause, Mr. Hasnain terminates his employment without good reason, or upon his death or permanent disability, he is entitled to receive his fully earned but unpaid base salary and accrued and unused PTO through the date of termination at the rate then in effect, plus all other amounts under any compensation plan or practice to which he is entitled.

The employment letter agreement with Mr. Hasnain also contains a Section 280G better-off cutback provision, which provides that, in the event that the payments or benefits provided to Mr. Hasnain pursuant to the employment letter or otherwise constitute parachute payments with the meaning of Section 280G of the Code, the payments or benefits to the executive will either be delivered in full or reduced to the extent necessary to avoid an excise tax under Section 4999 of the Code, whichever would result in him receiving the largest amount of payments or benefits on an after-tax basis.

For purposes of the employment letter agreement with Mr. Hasnain, “cause” means (1) a willful and material act of dishonesty by Mr. Hasnain in connection with the performance of his duties; (2) his conviction of, or plea of guilty or nolo contendere to, a felony (other than a traffic offense that does not result in a fatality), or any crime involving fraud or embezzlement that the board reasonably determines has had or is reasonably likely to have a materially detrimental effect on our reputation or business; (3) Mr. Hasnain’s gross misconduct in the performance of his duties; (4) Mr. Hasnain’s willful and material unauthorized use or disclosure of any proprietary information or trade secrets of ours or any other party to whom he owes an obligation of nondisclosure as a result of his relationship with us; (5) Mr. Hasnain’s willful and material breach of any obligations under any written agreement or written covenant with us; or (6) Mr. Hasnain’s continued willful and substantial failure to perform his duties as a member of the board or, during the term of his employment, his material employment duties that are lawfully assigned to him in good faith by the board (other than as a result of his death or disability) after written notice.

For purposes of the employment letter agreement with Mr. Hasnain, “good reason” means the occurrence of one or more of the following, without Mr. Hasnain’s written consent: (1) during the term of Mr. Hasnain’s employment: a material reduction in his base salary or target annual bonus; a material diminution of his title, duties, responsibilities or reporting lines; or a material change in the principal geographic location at which he must perform services, more than 50 miles from our head office; provided, however, that, prior to a change in control, an event occurring under this clause (1) in connection with his cessation of service as President and Chief Executive Officer will not constitute good reason if Mr. Hasnain remains serving as Chairman of the Board or Executive Chairman following such transition and neither clause (2) nor clause (3) is triggered as a result of such transition; or (2) at any time, his involuntary removal from the board or the failure of the stockholders to reelect him to the board, other than for cause; or (3) at any time, a material breach by us of the terms of the employment letter. Mr. Hasnain must provide written notice to us of the occurrence of any of the foregoing events or conditions within 60 days of the initial occurrence of such event and we will have a period of 30 days to cure such event or condition after receipt of such notice. His separation from service by reason of resignation for good reason must occur within 60 days following the expiration of the foregoing 30 day cure period.

For purposes of the 2019 Plan, a “change in control” is generally defined as: (1) a transaction or series of transactions (other than a registered offering of our common stock to the general public or a transaction described in clauses (x) and (y) of clause (3) below) whereby any “person” or “group” of “persons” (as such terms are used in Sections 13(d) and 14(d)(2) of the Exchange Act) (other than us and our affiliates) directly or indirectly acquires beneficial ownership of our securities possessing more than 50% of the total combined voting power of our securities outstanding immediately after such acquisition; or (2) during any period of two consecutive years, individuals who, at the beginning of such period, constitute the board of directors together with any new director(s) (other than a director designated by a person who entered into an agreement with us to effect a transaction described in clauses (1) or (3)) whose election by the board of directors or nomination for election by our stockholders was approved by a vote of at least two-thirds of the directors then still in office who either were directors at the beginning of the two-year period or whose election or nomination for election was previously so approved, cease for any reason to constitute a majority thereof; or (3) the consummation by us, directly or indirectly, of (a) a merger, consolidation, reorganization, or business combination or (b) a sale or other disposition of all or substantially all of our assets in any single transaction or series of related transactions or (c) the acquisition of assets or stock of another entity, in each case other than a transaction: (x) which results in our voting securities outstanding immediately before the transaction continuing to represent, directly or indirectly, at least a majority of the combined voting power of our outstanding voting securities or the successor entity’s outstanding voting securities immediately after the transaction, and (y) after which no person or group beneficially owns voting securities representing 50% or more of the combined voting power of us or the successor entity.

Employment Letters with Our Other Named Executive Officers

We have entered into employment letters with each of our other named executive officers. The employment letters with each of our named executive officers set forth their annual base salary and eligibility to receive an annual bonus with a target amount equal to 40% of his or her then-current annual base salary.

Pursuant to their employment letters, if we terminate the executive’s employment other than for cause (as defined below) or if the executive terminates his or her employment for good reason (as defined below), and other than as a result of death or disability, in either case prior to a change in control (as defined below) or more than 12 months following a change in control, he or she is entitled to the following payments and benefits, subject to the timely execution and non-revocation of a general release of claims in our favor: (1) continued payment of his or her base salary at the then-current rate for 9 months, paid in accordance to our payroll practices; and (2) payment of the full premium for continued health plan coverage for up to 9 months following the date of termination or, if earlier, up to the date the executive becomes eligible to receive equivalent or increased health plan coverage by means of subsequent employment or self-employment. The cash severance benefits described above shall be paid or commence on the first payroll period following the date the executive’s release becomes effective and the first payment shall include all accrued amounts from the date of termination, provided that if the period during which executive may deliver the release spans two calendar years, the initial payment date shall be no earlier than January 1 of the second calendar year.

If the executive’s employment is terminated by us other than for cause or by the executive for good reason, in each case within 12 months after a change in control, in lieu of the severance benefits described above, he or she is entitled to the following payments and benefits, subject to the timely execution and non-revocation of a general release of claims in our favor: (1) continued payment of his or her base salary at the then-current rate for 12 months, paid in accordance to our payroll practices; (2) a payment equal to his or her then current target annual bonus opportunity; (3) payment of the full premium for continued health plan coverage for up to 12 months following the date of termination or, if earlier, up to the date the executive becomes eligible to receive equivalent or increased health plan coverage by means of subsequent employment or self-employment; and (4) automatic full vesting and exercisability of the executive’s unvested stock awards. The cash severance benefits described above shall be paid or commence on the first payroll date following the date the executive’s release becomes effective and the first payment shall include all accrued amounts from the date of termination (and the full amount payable under clause (2)), provided that if the period during which executive may deliver the release spans two calendar years, the initial payment date shall be no earlier than January 1 of the second calendar year.

In addition, in the event of the executive’s termination of employment by reason of his or her death or disability, and subject to the timely execution and non-revocation of a general release of claims in our favor by the executive, then the greater of (1) 50% of the unvested portion of any equity awards then held by him or her immediately prior to such termination, and (2) the portion of such equity awards that would have otherwise vested in the 9 month period following the date of such termination of employment, will vest and will no longer be subject to restrictions or forfeiture on the date of such termination.

In the event we terminate the executive’s employment for any reason, including for cause, the executive terminates his or her employment without good reason, or upon his or her death or permanent disability, the executive is entitled to receive his or her fully earned but unpaid base salary and accrued and unused PTO through the date of termination at the rate then in effect, plus all other amounts under any compensation plan or practice to which the executive is entitled.

The employment letters also contain a Section 280G better-off cutback provision, which provides that, in the event that the payments or benefits provided to the executive pursuant to the employment letter or otherwise constitute parachute payments with the meaning of Section 280G of the Code, the payments or benefits to the executive will either be delivered in full or reduced to the extent necessary to avoid an excise tax under Section 4999 of the Code, whichever would result in the executive receiving the largest amount of payments or benefits on an after-tax basis.

For purposes of the employment letters with our named executive officers other than Mr. Hasnain, “cause” and “change in control” generally have the same meaning given to such terms under the employment letter agreement with Mr. Hasnain.

For purposes of the executive employment letters with our named executive officers other than Mr. Hasnain, “good reason” means the occurrence of any of the following events or conditions without the executive’s written consent: (1) a material reduction in the executive’s base salary or target annual bonus; (2) a material diminution of the executive’s title, duties, responsibilities or reporting lines; (3) a material change in the principal geographic location at which the executive must perform services, more than 50 miles from our head office; or (4) a material breach by us of the terms of the employment letter. The executive must provide written notice to us of the occurrence of any of the foregoing events or conditions within 60 days of the initial occurrence of such event and we will have a period of 30 days to cure such event or condition after receipt of such notice. An executive’s separation from service by reason of resignation for good reason must occur within 60 days following the expiration of the foregoing 30 day cure period.

Option Exercises and Stock Vested

The following table sets forth information regarding option exercises and stock awards that vested during 2020 with respect to our named executive officers.

____________________

(1)The amount shown for value realized on exercise of stock options equals (i) the number of shares of our common stock to which the exercise of the stock option related, multiplied by (ii) the difference between the per-share market price of the shares on the date of exercise and the per-share exercise price of the option. If the stock acquired upon exercise was sold on the day of exercise, the market price was determined as the actual sales price of the stock. If the stock acquired upon exercise was not sold on the day of exercise, the market price was determined as the closing price of the stock on the Nasdaq Stock Market on the exercise date.

(2)The value realized is based on the closing price of our common stock on the vesting date as reported on the Nasdaq Stock Market multiplied by the number of shares vested.

Potential Payments Upon Termination or Change in Control

The following table summarizes the potential payments to our named executive officers in four scenarios: (1) upon termination by us without cause or the executive’s resignation for good reason apart from a change in control; (2) upon termination by us following the executive’s permanent disability or as a result of the executive’s death; or (3) upon termination by us without cause or the executive’s resignation for good reason within three months prior to or 12 months following a change in control. The table assumes that the termination of employment or change in control, as applicable, occurred on December 31, 2020. The value of the accelerated vesting of stock and option awards was computed using $9.67, which was the price of our common stock at December 31, 2020 (less, in the case of option awards, the exercise price per share of such option awards).

The employment of Drs. Gujrathi and DuPont terminated effective November 16, 2020 and May 14, 2020, respectively. Accordingly, they are not included in the table below as they would not have been entitled to any benefits in the event of the occurrence of any of the triggering events described in the table on December 31, 2020. A description of the Transition Agreement with Dr. Gujrathi is provided under “— Employment Letters with Our Named Executive Officers” above.

This agreement provides for certain rights relating to the registration of their shares of common stock that were issued upon conversion of their convertible preferred stock and certain additional covenants made by us. Except for the registration rights (including the related provisions pursuant to which we have agreed to indemnify the parties to the investor rights agreement), all rights under this agreement terminated upon closing of our IPO. The registration rights will terminate five years following the closing our IPO.

Lycera Transactions

On March 8, 2019, we entered into a services agreement, or the Services Agreement, with Lycera Corp, which was amended and restated on February 1, 2020. Pursuant to the Services Agreement, Lycera provides certain research and development services to us, and we paid Lycera approximately $4.1 million for such services in the year ended December 31, 2020. In addition, on January 30, 2020, we entered into an asset purchase agreement with Lycera pursuant to which we acquired a preclinical program for approximately $2.8 million. Funds affiliated with ARCH Venture Partners are beneficial owners of more than 10% of our capital stock and Lycera’s capital stock. Kristina Burow is also a member of our and Lycera’s board of directors.

Director and Executive Officer Compensation

Please see “Proposal 1—Director Compensation” for additional information regarding compensation of our directors. Please see “Executive Compensation and Other Information” for additional information regarding compensation of our executive officers.

Employment Agreements

We have entered into employment letters with our executive officers. For more information regarding these agreements, see “Executive Compensation and Other Information—Employment Letters with our Named Executive Officers.”

Indemnification

We have entered into indemnification agreements with each of our directors and executive officers. These agreements, among other things, require us or will require us to indemnify each director (and in certain cases their related venture capital funds) and executive officer to the fullest extent permitted by Delaware law, including indemnification of expenses such as attorneys’ fees, judgments, fines and settlement amounts incurred by the director or executive officer in any action or proceeding, including any action or proceeding by or in right of us, arising out of the person’s services as a director or executive officer.

Our amended and restated certificate of incorporation and our amended and restated bylaws provide that we will indemnify each of our directors and officers to the fullest extent permitted by the Delaware General Corporation Law. Further, we have purchased a policy of directors’ and officers’ liability insurance that insures our directors and officers against the cost of defense, settlement or payment of a judgment under certain circumstances.

Stock Option Grants to Executive Officers and Directors

We have granted stock options to our executive officers and certain of our directors as more fully described in the sections entitled “Executive Compensation and Other Information” and “Proposal 1—Director Compensation.”

Other Transactions and Arrangements

Aaron Hasnain is the son of our Chairman, President and Chief Executive Officer, Faheem Hasnain, and currently serves as our Senior Director, Business Development at a salary of $173,430 per year, a position he has held since January 2018. Since January 1, 2020, we granted 9,662 restricted stock units and 16,225 options to Aaron Hasnain.

Policies and Procedures Regarding Related Party Transactions

Our board of directors has adopted a written related person transaction policy setting forth the policies and procedures for the review and approval or ratification of related-person transactions. This policy covers, with certain exceptions set forth in Item 404 of Regulation S-K under the Securities Act, any transaction, arrangement or relationship, or any series of similar transactions, arrangements or relationships in which we were or are to be a participant, where the amount involved exceeds $120,000 and a related person had or will have a direct or indirect material interest, including, without limitation, purchases of goods or services by or from the related person or entities in which the related person has a material interest, indebtedness, guarantees of indebtedness and employment by us of a related person. In reviewing and approving any such transactions, our audit committee is tasked to consider 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 and the extent of the related person’s interest in the transaction. All of the transactions described in this section occurred prior to the adoption of this policy.

STOCKHOLDER PROPOSALS

Proposals of stockholders intended to be presented at our annual meeting of stockholders to be held in 2022, including nominations of any person for election to our board of directors, must be received by us no later than December 28, 2021, which is 120 days prior to the one-year anniversary of the mailing date of the proxy statement for the 2021 annual meeting, in order to be included in our proxy statement and form of proxy card relating to that meeting, unless the date of the 2022 annual meeting of stockholders is changed by more than 30 days from the anniversary of our 2021 annual meeting, in which case the deadline for such proposals will be a reasonable time before we begin to print and send our proxy materials. These proposals must comply with the requirements as to form and substance established by the SEC in Rule 14a-8 of the Exchange Act for such proposals in order to be included in the proxy statement.

In addition, our amended and restated bylaws establish an advance notice procedure with regard to certain matters, including stockholder proposals and nominations of any person for election to our board of directors not included in our proxy statement, to be brought before an annual meeting of stockholders. In general, notice that meets the requirements set forth in our amended and restated bylaws must be received at our principal executive offices not less than 90 calendar days nor more than 120 calendar days prior to the first anniversary of the preceding year’s annual meeting. Therefore, to be presented at our 2022 annual meeting of stockholders, such a proposal must be received by us no earlier than February 9, 2022 and no later than March 11, 2022. However, if the date of the annual meeting is more than 30 days before or more than 60 days after such anniversary date, notice must be received no earlier than the close of business on the 120th day prior to such annual meeting and not later than the later of the close of business on the 90th calendar day prior to such annual meeting and the close of business on the tenth day following the day on which public disclosure of the date of such annual meeting was first made. If the stockholder fails to give notice by these dates, then the persons named as proxies in the proxies solicited by the board of directors for the 2022 annual meeting may exercise discretionary voting power regarding any such proposal. Stockholders are advised to review our amended and restated bylaws which also specify requirements as to the form and content of a stockholder’s notice.

ANNUAL REPORT

Any person who was a beneficial owner of our common stock on the record date may request a copy of our Annual Report on Form 10-K for the year ended December 31, 2020, and it will be furnished without charge upon receipt of a written request identifying the person so requesting a report as a stockholder of our company at such date. Requests should be directed to Gossamer Bio, Inc., 3013 Science Park Road, San Diego, CA 92121, Attention: Corporate Secretary. The company makes available free of charge on its website all of its filings that are made electronically with the SEC, including Forms 10-K, 10-Q and 8-K. These materials can be found at www.gossamerbio.com in the “Investors” section. Our Annual Report on Form 10-K does not constitute, and should not be considered, a part of this proxy solicitation material.

STOCKHOLDERS SHARING THE SAME ADDRESS

The rules promulgated by the SEC permit companies, brokers, banks or other intermediaries to deliver a single copy of proxy materials, or, where applicable, a Notice of Internet Availability of Proxy Materials, to households at which two or more stockholders reside. Each stockholder, however, still receives a separate proxy card if he or she receives paper copies. This practice, known as “householding,” is designed to reduce duplicate mailings and save significant printing and postage costs as well as natural resources. Stockholders sharing an address who have been previously notified by their broker, bank or other intermediary and have consented to householding will receive only one copy of our proxy statement and annual report or Notice of Internet Availability of Proxy Materials. If you would like to opt out of this practice for future mailings and receive a separate proxy statement and annual report or Notice of Internet Availability of Proxy Materials for each stockholder sharing the same address, please contact your broker, bank or other intermediary. You may also obtain a separate proxy statement or annual report or Notice of Internet Availability of Proxy Materials without charge by sending a written request to Gossamer Bio, Inc., 3013 Science Park Road, San Diego, CA 92121, Attention: Corporate Secretary or by calling (858) 684-1300. We will promptly send additional copies of the proxy statement or annual report or Notice of Internet Availability of Proxy Materials upon receipt of such request. Stockholders sharing an address that are receiving multiple copies of the proxy statement or annual report or Notice of Internet Availability of Proxy Materials can request delivery of a single copy of the proxy statement or annual report or Notice of Internet Availability of Proxy Materials by contacting their broker, bank or other intermediary or sending a written request to Gossamer Bio, Inc. at the address above or by calling (858) 684-1300.

OTHER MATTERS

We do not know of any business other than that described in this proxy statement that will be presented for consideration or action by the stockholders at the annual meeting. If, however, any other business is properly brought before the meeting, shares represented by proxies will be voted in accordance with the best judgment of the persons named in the proxies or their substitutes. All stockholders are urged to vote via the Internet, by telephone or to complete, sign and return a completed proxy card as soon as possible.
