We will mail the Notice of Availability on or about May 6, 2022, and it contains instructions on how to access those documents and to cast your vote over the Internet.

PROXY STATEMENT

FOR THE 2022 ANNUAL MEETING OF STOCKHOLDERS

GENERAL INFORMATION

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

We have elected to provide access to our proxy materials to our stockholders via the Internet. Accordingly, on or about May 6, 2022, we will begin mailing the Notice of Availability. Our proxy materials, including the Notice of the 2022 Annual Meeting of Stockholders, this proxy statement and the accompanying proxy card or, for shares held in street name (i.e., held for your account by a broker, bank or other nominee), a voting instruction form, and the 2021 Annual Report to Stockholders, or the 2021 Annual Report, will be mailed or made available to stockholders on the Internet on or about the same date.

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

Pursuant to rules adopted by the SEC, we are providing access to our proxy materials over the Internet rather than printing and mailing our proxy materials. We believe electronic delivery will expedite the receipt of such materials and will help lower our costs and reduce the environmental impact of our proxy materials. Therefore, the Notice of Availability was mailed to holders of record and beneficial owners of our common stock starting on or about May 6, 2022. The Notice of Availability provides instructions as to how stockholders may access and review our proxy materials, including the Notice of the 2022 Annual Meeting of Stockholders, this proxy statement, the proxy card and our 2021 Annual Report, on the website referred to in the Notice of Availability or, alternatively, how to request that a printed copy of the proxy materials, including a proxy card, be sent to them by mail. The Notice of Availability also provides voting instructions. In addition, stockholders of record may request to receive the proxy materials in printed form by mail, or electronically by e-mail, on an ongoing basis for future stockholder meetings. Please note that, while our proxy materials are available at the website referenced in the Notice of Availability and our Notice of the 2022 Annual Meeting of Stockholders, this proxy statement and our 2021 Annual Report are available on our website, no other information contained on either website is incorporated by reference in, or considered to be a part of, this proxy statement.

Who is soliciting my vote?

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

When is the record date for the Annual Meeting?

The record date for determination of stockholders entitled to vote at the Annual Meeting is the close of business on April 20, 2022.

How many votes can be cast by all stockholders?

There were 46,656,249 shares of our common stock, par value $0.0001 per share, outstanding on April 20, 2022, all of which are entitled to vote with respect to all matters to be acted upon at the Annual Meeting. Each stockholder of record is entitled to one vote for each share of our common stock held by such stockholder.

How do I vote?

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

•

By Internet. You may vote at www.proxydocs.com/GLUE, 24 hours a day, seven days a week, by following the instructions at that site for submitting your proxy electronically. You will be required to enter the control number provided in the Notice of Availability or the proxy card. Votes submitted through the Internet must be received prior to the commencement of the Annual Meeting.

•

By Telephone. You may vote using a touch-tone telephone by calling (866) 551-3217 (toll-free from the U.S., U.S. territories and Canada), 24 hours a day, seven days a week. You will be required to provide the control number provided in the Notice of Availability or the proxy card. Votes submitted by telephone must be received prior to the commencement of the Annual Meeting.

•

By Mail. If you requested and received a printed copy of the proxy materials, you may vote by mail by completing, signing and dating the enclosed proxy card and returning it in the enclosed prepaid envelope. Votes submitted through the mail must be received prior to June 15, 2022.

•

During the Annual Meeting. To vote during the live webcast of the Annual Meeting, you must first register in advance at www.proxydocs.com/GLUE prior to the deadline of June 13, 2022 at 5:00 p.m. Eastern Time. You will be required to enter the control number provided in the Notice of Availability or the proxy card. Upon completing your registration, you will receive further instructions via email, including your unique link to access the Annual Meeting. Please follow the instructions found on the Notice of Availability, proxy card and/or voting instruction form and subsequent instructions that will be delivered to you via email. If you vote by proxy prior to the Annual Meeting and choose to attend the Annual Meeting online, there is no need to vote again during the Annual Meeting unless you wish to change your vote.

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

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

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

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

How can I virtually attend the Annual Meeting?

To attend and participate in the Annual Meeting, stockholders will need to access the live webcast of the meeting. To do so, stockholders of record will need to visit www.proxydocs.com/GLUE and enter the control number provided in the Notice of Availability to pre-register for the Annual Meeting prior to the deadline of June 13, 2022 at 5:00 p.m. Eastern Time, and beneficial owners of shares held in street name will need to follow the instructions provided in the voting instructions form by the broker, bank or other nominee that holds their shares.

The live webcast of the Annual Meeting will begin promptly at 1:00 p.m. Eastern Time on June 15, 2022. We encourage stockholders to login to this website and access the webcast before the Annual Meeting’s start time by following the instructions in the email received on the morning of the Annual Meeting. You should allow ample time in advance of the meeting.

We will have technicians ready to assist you with any technical difficulties you may have accessing the Annual Meeting. If you encounter any difficulties accessing the virtual-only Annual Meeting platform, including any difficulties voting or submitting questions, please utilize the link on the meeting portal website titled “Having trouble? Please view the Meeting Access FAQs Guide,” this will have many FAQs as well as a technical support number that can be called before or during the meeting.

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

How do I revoke my proxy?

If you are a stockholder of record, you may revoke your proxy by (1) following the instructions on the Notice of Availability and submitting a new vote by Internet, telephone or mail using the procedures described in the “How

do I Vote?” section above before the applicable deadline, (2) attending and voting at the Annual Meeting (although attendance at the Annual Meeting will not in and of itself revoke a proxy), or (3) by filing an instrument in writing revoking the proxy or another duly executed proxy bearing a later date with our corporate secretary. Any written notice of revocation or subsequent proxy card must be received by our corporate secretary prior to the taking of the vote at the Annual Meeting. Such written notice of revocation or subsequent proxy card should be hand delivered to our corporate secretary or sent to our principal executive offices at Monte Rosa Therapeutics, Inc., 645 Summer Street, Suite 102, Boston, MA 02210, Attention: Corporate Secretary.

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

How is a quorum reached?

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

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

How is the vote counted?

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

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

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

Who pays the cost for soliciting proxies?

We are making this solicitation and will pay the entire cost of preparing and distributing the Notice of Availability and our proxy materials and soliciting votes. Our officers and employees may, without compensation other than their regular compensation, solicit proxies through further mailings, personal conversations, facsimile transmissions, e-mails, or otherwise. We will also reimburse brokers, banks, custodians, other nominees, and fiduciaries for forwarding these materials to their principals to obtain the authorization for the execution of proxies.

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

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

In addition, any stockholder proposal intended to be included in the proxy statement for the next annual meeting of our stockholders in 2023 must also satisfy the requirements of SEC Rule 14a-8 under the Exchange Act, and be received not later than December 28, 2022. If the date of the annual meeting is moved by more than 30 days

from the date contemplated at the time of the previous year’s proxy statement, then notice must be received within a reasonable time before we begin to print and send proxy materials. If that happens, we will publicly announce the deadline for submitting a proposal in a press release or in a document filed with the SEC.

How can I know the voting results?

We plan to announce preliminary voting results at the Annual Meeting and will publish final results in a Current Report on Form 8-K, or Form 8-K, to be filed with the SEC within four business days following 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 Annual 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 NO. 1 – ELECTION OF CLASS I DIRECTORS

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

(1)

the Class I directors are Christine Siu, Kimberly Blackwell and Bradley Bolzon, and their terms will expire at the Annual Meeting;

(2)

the Class II directors are Andrew Schiff and Chandra Leo, and their terms will expire at the annual meeting of stockholders to be held in 2023; and

(3)

the Class III directors are Markus Warmuth, Alexander Mayweg and Ali Behbahani, and their terms will expire at the annual meeting of stockholders to be held in 2024.

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

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

Our board of directors has nominated Christine Siu and Kimberly Blackwell for election as the Class I directors at the Annual Meeting. The nominees are presently directors, and each has indicated a willingness to continue to serve as a director, if elected. If the nominees become unable or unwilling to serve, however, the proxies may be voted for a substitute nominee selected by our board of directors. On April 25, 2022, Dr. Bolzon notified us of his decision to retire from service on our board of directors following completion of his current term and will not stand for re-election at the Annual Meeting.

Our Compensation, Nomination and Corporate Governance Committee Policies and Procedures for Director Candidates, or the Director Guidelines, provide that the value of diversity should be considered in determining director candidates as well as other factors such as a candidate’s character, judgment, skills, education, expertise and absence of conflicts of interest. Our priority in selection of board members is identification of members who will further the interests of our stockholders through their established records of professional accomplishment, their ability to contribute positively to the collaborative culture among board members, and their knowledge of our business and understanding of the competitive landscape in which we operate and adherence to high ethical standards. While our Director Guidelines do not specify assigned weights to particular criteria, our board of directors and compensation, nomination and corporate governance committee believe it is essential that members of our board of directors represent diverse viewpoints and that the backgrounds and qualifications of our directors, considered as a group, should provide a composite mix of experience, knowledge and abilities that will allow our board to promote our strategic objectives and fulfill its responsibilities to our stockholders. Diversity includes race, ethnicity, age, and gender and is also broadly construed to take into consideration many other factors, including industry knowledge, operational experience, scientific and academic expertise and personal backgrounds. The composition of our board of directors currently includes two individuals who are diverse under the proposed Nasdaq listing rule regarding board diversity. Under the proposed Nasdaq listing rule, currently subject to review and approval by the SEC, directors who self-identify as (i) female, (ii) an underrepresented minority, or (iii) LGBTQ+ are defined as being diverse.

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

Nominees for Election as Class I Directors

The following table identifies our director nominees, and sets forth their principal occupation and business experience during the last five years and their ages as of March 31, 2022.

Vote Required and Board of Directors’ Recommendation

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

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

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

The board of directors recommends voting “FOR” the election of Christine Siu and Kimberly Blackwell, as the Class I directors, to serve for a three-year term ending at the annual meeting of stockholders to be held in 2025.

PROPOSAL NO. 2 – RATIFICATION OF THE APPOINTMENT OF Deloitte & Touche LLP AS MONTE ROSA THERAPEUTICS’ INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE FISCAL YEAR ENDING DECEMBER 31, 2022

Monte Rosa Therapeutics’ stockholders are being asked to ratify the appointment by the audit committee of the board of directors of Deloitte & Touche, LLP, or Deloitte, as Monte Rosa Therapeutics’ independent registered public accounting firm for the fiscal year ending December 31, 2022.

The audit committee is solely responsible for selecting Monte Rosa Therapeutics’ independent registered public accounting firm for the fiscal year ending December 31, 2022. Stockholder approval is not required to appoint Deloitte as Monte Rosa Therapeutics’ independent registered public accounting firm. However, the board of directors believes that submitting the appointment of Deloitte to the stockholders for ratification is good corporate governance. If the stockholders do not ratify this appointment, the audit committee will reconsider whether to retain Deloitte. If the selection of Deloitte is ratified, the audit committee, at its discretion, may direct the appointment of a different independent registered public accounting firm at any time it decides that such a change would be in the best interest of Monte Rosa Therapeutics and its stockholders.

A representative of Deloitte is expected to virtually attend the Annual Meeting and will have an opportunity to make a statement if he or she desires to do so and to respond to appropriate questions from our stockholders.

Independent Registered Public Accounting Firm Fees

We incurred the following fees from Deloitte for the audit of the consolidated financial statements and for other services provided during the years ended December 31, 2021 and 2020.


Fee Category	Fiscal Year 2021 ($)		Fiscal Year 2020 ($)
Audit fees	$	1,436,727	$	61,277
Audit-related fees		—		—
Tax fees		—		59,366
All other fees		1,895		—
Total Fees	$	1,438,622	$	120,643

Audit Committee Pre-approval Policy and Procedures

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

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

During fiscal years 2021 and 2020, no services were provided to us by Deloitte other than in accordance with the pre-approval policies and procedures described above.

Vote Required and Board of Directors’ Recommendation

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

The board of directors recommends voting “FOR” Proposal No. 2 to ratify the appointment of Deloitte & Touche LLP LLC as Monte Rosa Therapeutics’ independent registered public accounting firm for the fiscal year ending December 31, 2022.

CORPORATE GOVERNANCE

Director Nomination Process

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

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

•

Nominees should demonstrate high standards of personal and professional ethics and integrity.

•

Nominees should have proven achievement and competence in the nominee’s field and the ability to exercise sound business judgment.

•

Nominees should have skills that are complementary to those of the existing board.

•

Nominees should have the education, expertise and business acumen to assist and support management and make significant contributions to the Company’s success.

•

Nominees should have an understanding of the fiduciary responsibilities that are required of a member of the board of directors and the commitment of time and energy necessary to diligently carry out those responsibilities.

Stockholders may recommend individuals to the compensation, nomination and corporate governance committee for consideration as potential director candidates. Any such proposals should be submitted to our corporate secretary at our principal executive offices no later than the close of business on the 90th day nor earlier than the close of business on the 120th day prior to the one-year anniversary of the date of the preceding year’s annual meeting and should include appropriate biographical and background material to allow the compensation, nomination and corporate governance committee to properly evaluate the potential director candidate and the number of shares of our stock beneficially owned by the stockholder proposing the candidate. Stockholder proposals should be addressed to Monte Rosa Therapeutics, Inc., 645 Summer Street, Suite 102, Boston, MA 02210, Attention: Corporate Secretary. Assuming that biographical and background materials have been provided on a timely basis in accordance with our bylaws, any recommendations received from stockholders will be evaluated in the same manner as potential nominees proposed by the compensation, nomination and corporate governance committee. If our board of directors determines to nominate a stockholder recommended candidate and recommends his or her election, then his or her name will be included on our proxy card for the next annual meeting of stockholders. See “Stockholder Proposals” for a discussion of submitting stockholder proposals.

Director Independence

Our common stock was approved for listing on The Nasdaq Global Select Market. Under the Nasdaq listing rules, independent directors must comprise a majority of a listed company’s board of directors within twelve months from the date of listing. In addition, the Nasdaq rules require that, subject to specified exceptions, each member of a listed company’s audit, compensation and nominating and corporate governance committees be independent and that audit committee members also satisfy independence criteria set forth in Rule 10A-3 under the Exchange Act and that compensation, nomination and corporate governance committee members satisfy independence criteria set forth in Rule 10C-1 under the Exchange Act. Under applicable Nasdaq rules, a director will only qualify as an “independent director” if, in the opinion of the listed company’s board of directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. In order to be considered independent for purposes of Rule 10A-3 under the Exchange Act, a member of an audit committee of a listed company may not, other than in his or her capacity as a member of the audit committee, the board of directors, or any other board committee: (1) accept, directly or indirectly, any consulting, advisory, or other compensatory fee from the listed company or any of its subsidiaries, other than compensation for board service; or (2) be an affiliated person of the listed company or any of its subsidiaries. In order to be considered independent for purposes of Rule 10C-1, the board of directors must consider, for each member of a compensation, nomination and corporate governance committee of a listed

company, all factors specifically relevant to determining whether a director has a relationship to such company which is material to that director’s ability to be independent from management in connection with the duties of a compensation, nomination and corporate governance committee member, including, but not limited to: the source of compensation of the director, including any consulting advisory or other compensatory fee paid by such company to the director, and whether the director is affiliated with the company or any of its subsidiaries or affiliates.

Our board of directors has determined that all members of the board of directors, except Markus Warmuth, Alexander Mayweg and Bradley Bolzon are independent directors, including for purposes of the rules of Nasdaq and the SEC. Dr. Bolzon notified us of his decision to retire from service on our board of directors following the completion of his current term and will not stand for re-election at the Annual Meeting. In making such independence determination, our board of directors considered the relationships that each director has with us and all other facts and circumstances that our board of directors deemed relevant in determining their independence, including the beneficial ownership of our capital stock by each director. In considering the independence of the directors listed above, our board of directors considered the association of our directors with the holders of more than 5% of our common stock. There are no family relationships among any of our directors or executive officers.

Board Committees

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

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

Compensation, Nomination and Corporate Governance Committee

Andrew Schiff, Ali Behbahani and Kimberly Blackwell serve on the compensation, nomination and corporate governance committee, which is chaired by Andrew Schiff. Our board of directors has determined that each member of the compensation, nomination and corporate governance committee is “independent” as defined in the applicable Nasdaq rules. During the fiscal year ended December 31, 2021, the compensation, nomination and corporate governance committee met three (3) times. The compensation, nomination and corporate governance committee’s responsibilities include:

•

annually reviewing and recommending to the board of directors the corporate goals and objectives relevant to the compensation of our Chief Executive Officer;

•

evaluating the performance of our Chief Executive Officer in light of such corporate goals and objectives and, based on such evaluation, determining and approving the compensation of our Chief Executive Officer

•

reviewing and approving the compensation of our other executive officers;

•

reviewing and establishing our overall management compensation, philosophy and policy;

•

•

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

Identifying and Evaluating Director Nominees.

Our board of directors is responsible for filling vacancies on our board of directors and for nominating candidates for election by our stockholders each year in the class of directors whose term expires at the relevant annual meeting. The board of directors delegates the selection and nomination process to the compensation, nomination and corporate governance committee, with the expectation that other members of the board of directors, and of management, will be requested to take part in the process as appropriate.

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

Board and Committee Meetings Attendance

The full board of directors met four (4) times during 2021. During 2021, each member of the board of directors attended in person or participated in 75% or more of the aggregate of (i) the total number of meetings of the board of directors (held during the period for which such person has been a director), and (ii) the total number of meetings held by all committees of the board of directors on which such person served (during the periods that such person served). The Company encourages its directors to attend the annual meeting of stockholders.

Director Attendance at Annual Meeting of Stockholders

Directors are responsible for attending the annual meeting of stockholders to the extent practicable. We did not hold an annual meeting of stockholders during the time we were a public company in 2021.

Policy on Trading, Pledging and Hedging of Company Stock

Certain transactions in our securities (such as purchases and sales of publicly traded put and call options, and short sales) create a heightened compliance risk or could create the appearance of misalignment between

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

Code of Business Conduct and Ethics

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

Board Leadership Structure and Board’s Role in Risk Oversight

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

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

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

Communication with the Directors of Monte Rosa Therapeutics

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

c/o Monte Rosa Therapeutics, Inc.
645 Summer Street, Suite 102

Boston, MA 02210

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

A copy of any such written communication may also be forwarded to the Company’s general counsel and a copy of such communication may be retained for a reasonable period of time. The director may discuss the matter with

the Company’s general counsel, with independent advisors, with non-management directors, or with the Company’s management, or may take other action or no action as the director determines in good faith, using reasonable judgment and applying his or her own discretion.

Communications may be forwarded to other directors if they relate to important substantive matters and include suggestions or comments that may be important for other directors to know. In general, communications relating to corporate governance and long-term corporate strategy are more likely to be forwarded than communications relating to ordinary business affairs, personal grievances and matters as to which we tend to receive repetitive or duplicative communications.

The audit committee oversees the procedures for the receipt, retention, and treatment of complaints received by the Company regarding accounting, internal accounting controls, or audit matters, and the confidential, anonymous submission by employees of concerns regarding questionable accounting, internal accounting controls or auditing matters. The Company has also established a toll-free telephone number for the reporting of such activity, which is (844) 426-0141.

Non-Employee Director Compensation Policy

Prior to our initial public offering in June 2021, we paid each of Kimberly Blackwell, M.D. and Christine Siu an annual retainer for services as a member of our board of directors equal to $35,000 and paid no other cash fees to any other non-employee directors. Each of Dr. Blackwell and Ms. Siu also received an option to purchase 28,850 shares of our common stock upon her appointment to the board of directors. Subject to the director’s continuous service on our board of directors, these stock options vest 25% on the applicable vesting commencement date and in 36 equal monthly installments monthly thereafter, subject to 100% acceleration upon a change of control. No other non-employee directors were eligible to receive any equity awards for service as a member of our board of directors prior to our initial public offering.

In connection with our initial public offering and upon the recommendation of our compensation, nomination and corporate governance committee, we implemented a formal policy pursuant to which we pay our non-employee directors a cash retainer for service on the board of directors and for service on each committee on which the director is a member. The chairman of each committee receives a higher retainer for such service. The fees paid to non-employee directors for service on the board of directors and for service on each committee of the board of directors on which the director is a member are as follows:


Annual Retainer for Board Membership
Annual service on the board of directors	$	35,000
Additional compensation for service as non-executive chair of the board of directors	$	30,000
Additional Annual Retainer for Committee Membership
Annual service as member of the audit committee (other than chair)	$	7,500
Annual service as chair of the audit committee	$	15,000
Annual service as member of the compensation, nomination and corporate governance committee (other than chair)	$	5,000
Annual service as chair of the compensation, nomination and corporate governance committee	$	10,000

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

In addition, each new non-employee director elected to our board of directors will be granted an option to purchase 130,000 shares of our common stock on the date of such director’s election or appointment to the board of directors, which will vest ratably in thirty-six (36) equal monthly installments following the grant date, subject to the director’s continued service on our board of directors through such vesting date. On the date of each annual meeting of stockholders of our company, each continuing non-employee director will be granted an option to purchase 65,000 shares of our common stock, which will vest in full upon the earlier to occur of the first anniversary of the date of grant or the date of the next annual meeting, subject to the director’s continued service on our board of directors through such vesting date, subject to 100% acceleration upon a change in control.

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

Employee directors receive no additional compensation for their service as a director.

Narrative to 2021 Summary Compensation Table

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

Our compensation, nomination and corporate governance committee is authorized to retain the services of one or more executive compensation advisors, as it sees fit, in connection with the establishment of our executive compensation programs and related policies. In fiscal year 2021, the compensation, nomination and corporate governance committee continued to retain Radford, an AonHewitt Company (“Radford”) to provide it with market information, analysis and other advice relating to executive compensation on an ongoing basis. The compensation, nomination and corporate governance committee engaged Radford to, among other things, assist in developing a group of peer companies to help us determine overall compensation for our executive officers, as well as to assess each separate element of compensation. The goal was to ensure that the compensation we offer to our executive officers, individually as well as in the aggregate, is competitive and aligned with our business and executive talent requirements. We do not believe the retention of, and the work performed by, Radford creates any conflict of interest because Radford performs no other work for the Company besides advising the compensation, nomination and corporate governance committee.

Our compensation, nomination and corporate governance committee is responsible for determining the compensation for all executive officers. Based on its discretion, taking into account the factors noted above, the compensation, nomination and corporate governance committee sets the compensation for each executive officer, including for the Chief Executive Officer, without the Chief Executive Officer present.

Base Salaries

Base salaries for our named executive officers are reviewed periodically and adjusted from time to time based on factors including market-competitive compensation levels, job responsibilities, individual performance and

experience. The 2021 base salaries for Dr. Warmuth, Dr. Janku, and Dr. Wallace were $564,600, $400,000, and $417,000, respectively. Dr. Janku and Dr. Wallace, who joined the Company in 2021 received pro-rated base salaries for their partial year of service in fiscal year 2021.

Annual Bonuses

For the fiscal year 2021, each named executive officer was eligible to earn an annual cash bonus based on achievement of certain company and individual-performance goals. The target annual bonus for each of Dr. Warmuth, Dr. Janku, and Dr. Wallace were 50%, 40%, and 40% of each of the named executive officer’s annual base salary, which were prorated for Dr. Janku’s and Dr. Wallace’s partial year of service in 2021.

Equity Compensation

Our equity grant program is intended to align the interests of our named executive officers with those of our stockholders and to motivate them to make important contributions to our performance. In 2021, we granted stock options to each of our named executive officers, as reflected in the “Outstanding Equity Awards at 2021 Fiscal Year End Table” below.

401(k) Plan

We maintain a tax-qualified retirement plan that provides all regular U.S. employees with an opportunity to save for retirement on a tax-advantaged basis. Under our 401(k) plan, participants may elect to defer a portion of their compensation on a pre-tax basis or after tax (Roth) basis subject to applicable annual limits under the Code. Pre-tax contributions are allocated to each participant’s individual account and are then invested in selected investment alternatives according to the participants’ directions. Employee elective deferrals are 100% vested at all times. As a U.S. tax-qualified retirement plan, contributions to the 401(k) plan and earnings on those contributions are not taxable to the employees until distributed from the 401(k) plan and all contributions are deductible by us when made and earnings on Roth contributions are not taxable when distributed from the 401(k) Plan. We make safe-harbor match contributions of 100% of the first 4% of each participant’s eligible compensation.

Other Benefits

Our named executive officers are eligible to participate in our employee benefit plans on the same basis as our other employees, including our health and welfare plans.

Employment Arrangements with Our Named Executive Officers

We entered into an employment agreements with each of Dr. Warmuth, Dr. Janku, and Dr. Wallace, which superseded each such named executive officer’s existing offer letter, and which became effective upon our initial public offering. The new employment agreements contain substantially similar terms that provide for each of the named executive officer’s continued employment and annual base salary, and set forth the terms of their annual bonus, the at-will nature of their employment, certain expense reimbursements, the terms of severance payments payable upon certain terminations of employment and their eligibility to participate in our benefit plans generally.

In the event that Dr. Warmuth’s, Dr. Janku’s, or Dr. Wallace’s service with the Company is terminated without “cause” or for “good reason” (in each case, as defined in his employment agreement), within three month prior to or twelve months after a “change in control” (as defined in his employment agreement), such named executive officer will be entitled to the following severance benefits, subject to the executive executing a separation agreement and it becoming effective, (i) a lump-sum payment equal to equal to the sum of (a) 12 months (or, in the case of Dr. Warmuth, 18 months) of such named executive officer’s then-current base salary or the base salary in effect immediately prior to the change in control, if higher, plus (b) one times (or, in the case of Dr. Warmuth, 1.5 times) such named executive officer’s annual target bonus for the then-current year; (ii) up to 12 months (or, in the case of Dr. Warmuth, 18 months) of the employer portion of COBRA premium payments; and (iii) in the case of Dr. Warmuth, any vested stock options granted prior to the effective date of his employment agreement shall be exercisable until the earlier of the expiration date of such options or the first anniversary of his date of termination unless the equity documents pursuant to which such stock options are granted require or authorize earlier termination in connection with a liquidation or sale of the Company.

In the event that Dr. Warmuth’s service with the Company is terminated without “cause” or for “good reason,” in each case, other than in connection with a change in control, such named executive officer will be entitled to the following severance benefits, subject to such executive executing a separation agreement and release and it becoming effective: (i) payments equal to the sum of (a) 12 months of Dr. Warmuth’s then-current base salary, plus (b) his annual target bonus for the then-current year; and (ii) up to 12 months of the employer portion of COBRA premium payments.

In the event that Dr. Janku’s or Dr. Wallace’s service with the Company is terminated without “cause” or for “good reason,” in each case, other than in connection with a change in control, such named executive officer will be entitled to the following severance benefits, subject to such executive executing a separation agreement and release and it becoming effective: (i) payments equal to 12 months of such named executive officer’s then-current base salary, and (ii) up to 12 months of the employer portion of COBRA premium payments.

Upon the occurrence of a change of control, all payments and benefits received by Dr. Warmuth, Dr. Janku, and Dr. Wallace in connection with a change of control that constitute “excess parachute payments” under Section 280G of the Code will be subject to a modified economic cutback treatment such that the “excess parachute

payments” to be received by each such affected named executive officer will either be (i) paid in full or (ii) reduced below such named executive officer’s threshold amount under Code Section 280G in order to avoid triggering the excise tax that would otherwise be payable on such “excess parachute payment” amounts.

In addition, each of our named executive officers previously entered into our standard confidential information, non-competition, non-solicitation, and invention assignment agreement with us which continues to remain in effect and contains protections of confidential information, requires the assignment of inventions and contains other restrictive covenants.

Compensation Risk Assessment

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

Ridgeline also provided us with the services of a team of scientists. In 2021, we transitioned to a more limited consulting arrangement whereby Ridgeline invoiced us for services performed on an ongoing monthly basis.

Total service fees incurred were $7.8 million for the year ended December 31, 2021.

Stock Option Grants to Executive Officers

We have granted stock options to our named executive officers as more fully described in the section entitled “Executive Compensation.”

Indemnification Agreements

We have entered into agreements to indemnify our directors and executive officers. These agreements, among other things, require us to indemnify these individuals for certain expenses (including attorneys’ fees), judgments, fines and settlement amounts incurred by such person in any action or proceeding on account of any services undertaken by such person on behalf of our Company or any other company or enterprise to which such person provides services at our request to the maximum extent allowed under Delaware law.

Agreements with Our Stockholders

In connection with our preferred stock financings prior to our IPO, we entered into investors’ rights, voting and right of first refusal and co-sale agreements as well as management rights letters containing registration rights, information rights, voting rights and rights of first refusal, among other things, with certain holders of our convertible preferred stock and certain holders of our common stock. The management rights letters provide for certain information rights and rights to consult with our management. These stockholder agreements and management rights letters terminated immediately prior to the completion of our IPO, other than the provisions relating to registration rights, which continued in effect following the completion of our IPO and entitle the holders of such rights to demand that we file a registration statement, subject to certain limitations, and to request that their shares be covered by a registration statement that we are otherwise filing.

Related Person Transaction Policy

Our board of directors adopted a written related person transaction policy providing that transactions with our directors, executive officers and holders of five percent or more of our voting securities and their affiliates, each a related person, must be approved by the audit committee. This policy became effective on June 23, 2021 in connection with our IPO. Pursuant to this policy, the audit committee has the primary responsibility for reviewing and approving or disapproving “related person transactions,” which are transactions between us and related persons in which the aggregate amount involved exceeds or may be expected to exceed $120,000 and in which a related person has or will have a direct or indirect material interest. For purposes of this policy, a related person will be defined as a director, executive officer, nominee for director, or greater than 5% beneficial owner of our common stock, in each case since the beginning of the most recently completed year, and their immediate family members.

REPORT OF THE AUDIT COMMITTEE

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

In connection with these responsibilities, the audit committee reviewed and discussed with management and the independent registered public accounting firm the audited consolidated financial statements of Monte Rosa Therapeutics for the fiscal year ended December 31, 2021. The audit committee also discussed with the independent registered public accounting firm the matters required to be discussed by the PCAOB’s Auditing Standard No. 1301, Communication with Audit Committees. In addition, the audit committee received written communications from the independent registered public accounting firm confirming their independence as required by the applicable requirements of the PCAOB and has discussed with the independent registered public accounting firm their independence.

HOUSEHOLDING

We have adopted a procedure called “householding,” which the SEC has approved. Under this procedure, we deliver a single copy of the Notice of Internet Availability and, if applicable, our proxy materials to multiple stockholders who share the same address, unless we have received contrary instructions from one or more of such stockholders. This procedure reduces our printing costs, mailing costs and fees. Stockholders who participate in householding will continue to be able to access and receive separate proxy cards. Upon written or oral request, we will deliver promptly a separate copy of the Notice of Internet Availability and, if applicable, our proxy materials to any stockholder at a shared address to which we delivered a single copy of any of these materials. This request may be submitted by contacting Monte Rosa Therapeutics, Inc., 645 Summer Street, Suite 102, Boston, MA 02210, Attention: Corporate Secretary, telephone: (617) 949-2643. Any such stockholder may also contact our Corporate Secretary using the above contact information if he or she would like to receive separate proxy statements, notice of internet availability and annual reports in the future. If you want to receive separate copies of the proxy statement or annual report to stockholders in the future, or if you are receiving multiple copies and would like to receive only one copy per household, you should contact your bank, broker or other nominee record holder, or you may contact us at the above address and phone number.

STOCKHOLDER PROPOSALS

A stockholder who would like to have a proposal considered for inclusion in our 2023 proxy statement must submit the proposal in accordance with the procedures outlined in Rule 14a-8 of the Exchange Act so that it is received by us no later than December 28, 2022. However, if the date of the annual meeting of stockholders in 2023 (the “ 2023 Annual Meeting”) is changed by more than 30 days from the date of the previous year’s meeting, then the deadline is a reasonable time before we begin to print and send our proxy statement for the 2023 Annual Meeting. SEC rules set standards for eligibility and specify the types of stockholder proposals that may be excluded from a proxy statement. Stockholder proposals should be addressed to Monte Rosa Therapeutics, Inc., 645 Summer Street, Suite 102, Boston, MA 02210, Attention: Corporate Secretary.

If a stockholder wishes to propose a nomination of persons for election to our board of directors or present a proposal outside of Rule 14a-8 of the Exchange Act at an annual meeting but does not wish to have the proposal considered for inclusion in our proxy statement and proxy card, our bylaws establish an advance notice procedure for such nominations and proposals. Stockholders at an annual meeting may only consider proposals or nominations specified in the notice of meeting or brought before the meeting by or at the direction of the board of directors or by a stockholder of record on the record date for the meeting, who is entitled to vote at the meeting and who has delivered timely notice in proper form to our corporate secretary of the stockholder’s intention to bring such business before the meeting.

In accordance with the advance notice procedure specified in our bylaws, for any stockholder proposal submitted outside the processes of Rule 14a-8 of the Exchange Act to be considered timely, the required notice must be in writing and received by our corporate secretary at our principal executive offices not later than the close of business on the 90th day nor earlier than the close of business on the 120th day prior to the first anniversary of the preceding year’s annual meeting. However, in the event that the date of the annual meeting is convened more than 30 days before or more than 60 days after the first anniversary of the preceding year’s annual meeting, or if no annual meeting were held in the preceding year, a stockholder’s notice must be so received not later than the close of business on the later of (i) the 90th day prior to the scheduled date of such annual meeting or (ii) the 10th day following the day on which public announcement of the date of such annual meeting was first made. Accordingly, for stockholder proposals to be brought before the 2023 Annual Meeting of Stockholders, the required notice must be received by our corporate secretary at our principal executive offices not later than March 17, 2023 and no earlier than February 15, 2023. Stockholder proposals and the required notice should be addressed to Monte Rosa Therapeutics, Inc., 645 Summer Street, Suite 102, Boston, MA 02210, Attention: Corporate Secretary.

OTHER MATTERS

Our board of directors does not know of any other matters to be brought before the Annual Meeting. If any other matters not mentioned in this proxy statement are properly brought before the Annual Meeting, the individuals named in the enclosed proxy intend to use their discretionary voting authority under the proxy to vote the proxy in accordance with their best judgment on those matters.
