NOTICE OF 2023 ANNUAL MEETING OF STOCKHOLDERS

To Be Held on Tuesday, June 13, 2023

Dear Stockholder:

You are cordially invited to the 2023 Annual Meeting of Stockholders (the “Annual Meeting”) of Decibel Therapeutics, Inc. The Annual Meeting will be held exclusively via the Internet in a virtual meeting format at www.proxydocs.com/DBTX on Tuesday, June 13, 2023 at 10:00 a.m. Eastern Time. At the meeting, the stockholders will consider and vote on the following matters:

The election of one Class II director, Saraswathy Nochur, Ph. D., to serve for a three-year term expiring at the 2026 annual meeting of stockholders and until her successor has been duly elected and qualified;

The approval of an amendment to our Restated Certificate of Incorporation to reflect new Delaware law provisions regarding officer exculpation;

The ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2023; and

The transaction of any other business that may properly come before the Annual Meeting or any adjournment or postponement thereof.

You may attend the Annual Meeting online at www.proxydocs.com/DBTX, where you will be able to vote your shares electronically during the meeting and submit questions during the meeting. Stockholders will not be able to attend the Annual Meeting in person. In order to attend the Annual Meeting online, you must register in advance at www.proxydocs.com/DBTX prior to the commencement of the Annual Meeting. Upon completing your registration, you will receive further instructions via email, including a unique link that will allow you access to the Annual Meeting and to vote and submit questions during the Annual Meeting. Please follow the instructions found on your Notice Regarding the Availability of Proxy Materials, Proxy Card and/or Voting Instruction Card and subsequent instructions that will be delivered to you via email.

Stockholders of record at the close of business on April 17, 2023 will be entitled to notice of and to vote electronically during the Annual Meeting or any adjournment or postponement thereof. A list of registered stockholders as of the close of business on the record date will be available for examination by any stockholder for any purpose germane to the Annual Meeting during normal business hours at our principal executive officers during the 10-day period ending on the day before the Annual Meeting. We have elected to provide access to our proxy materials over the Internet under the Securities and Exchange Commission’s “notice and access” rules. We believe that providing our proxy materials over the Internet expedites stockholders’ receipt of proxy materials, lowers costs and reduces the environmental impact of our annual meeting.

We encourage all stockholders to attend the Annual Meeting online. However, whether or not you plan to attend the Annual Meeting, we encourage you to read the proxy statement and submit your proxy or voting instructions as soon as possible. Please review the instructions on each of your voting options described in the proxy statement.

To Be Held on Tuesday, June 13, 2023

INFORMATION CONCERNING SOLICITATION AND VOTING

This proxy statement contains information about our 2023 annual meeting of stockholders, or the Annual Meeting. The meeting will be held on Tuesday, June 13, 2023 at 10:00 a.m. Eastern Time. The Annual Meeting will be held exclusively via the Internet in a virtual meeting format at www.proxydocs.com/DBTX. There will not be a physical meeting location, and stockholders will not be able to attend the Annual Meeting in person. Except where the context otherwise requires, references to “Decibel,” “the Company,” “we,” “us,” “our” and similar terms refer to Decibel Therapeutics, Inc. References to our website are inactive textual references only and the contents of our website are not incorporated by reference into this proxy statement.

This proxy statement and the enclosed proxy card are being furnished in connection with the solicitation of proxies by our board of directors for use at the Annual Meeting and at any adjournment or postponement of that meeting. All proxies will be voted in accordance with the instructions they contain. If you do not specify your voting instructions, your proxy will be voted in accordance with the recommendations of our board of directors. We are making this proxy statement, the related proxy card and our annual report to stockholders for the fiscal year ended December 31, 2022, or our 2022 Annual Report, available to stockholders for the first time on or about April 28, 2023.

A copy of our Annual Report on Form 10-K for the fiscal year ended December 31, 2022, as filed with the Securities and Exchange Commission, or SEC, except for exhibits, will be furnished without charge to any stockholder upon written or oral request to Decibel Therapeutics, Inc., 1325 Boylston Street, Suite 500, Boston, Massachusetts 02215 or by calling 866-648-8133, by emailing paper@investorelections.com or by submitting a request over the Internet at www.investorelections.com/DBTX. This proxy statement and our Annual Report on Form 10-K for the fiscal year ended December 31, 2022 are also available on the SEC’s website at www.sec.gov.

IMPORTANT INFORMATION ABOUT THE ANNUAL MEETING AND VOTING


Q.	Why do I have access to these materials?
A.	We have made these proxy materials available to you because our board of directors is soliciting your proxy to vote at the Annual Meeting to be held on June 13, 2023 at 10:00 a.m. Eastern Time, including at any adjournments or postponements of the meeting. As a holder of common stock as of the close of business on April 17, 2023, you are invited to attend the Annual Meeting online and are requested to vote on the items of business described in this proxy statement. This proxy statement includes information that we are required to provide to you under the rules adopted by the SEC and is designed to assist you in voting your shares.
Q.	Why did I receive a notice in the mail regarding the Internet availability of proxy materials instead of a full set of proxy materials?
A.	In accordance with SEC rules, we have elected to provide access to our proxy materials, including this proxy statement and our 2022 Annual Report, over the Internet. Accordingly, we plan to send a Notice Regarding the Availability of Proxy Materials, or the Notice, to our stockholders of record entitled to vote at the Annual Meeting with instructions for accessing the proxy materials. We plan to mail the Notice on or about April 28, 2023.
	All stockholders entitled to vote at the Annual Meeting will have the ability to access the proxy materials by visiting the website referred to in the Notice, www.proxydocs.com/DBTX. This makes the proxy distribution process more efficient and less costly and helps conserve natural resources. The Notice also contains instructions to request to receive a printed set of the proxy materials. You may request a paper copy of the proxy materials over the Internet at www.investorelections.com/DBTX, by emailing paper@investorelections.com, or by calling 866-648-8133.
	The Notice also identifies the date and time of, and web address for, the Annual Meeting; the matters to be acted upon at the meeting and our board of directors’ recommendation with regard to each matter; a toll-free telephone number, an e-mail address, and a website where stockholders can request to receive, free of charge, a paper or e-mail copy of the proxy statement, our 2022 Annual Report, and a form of proxy card relating to the Annual Meeting; and information on how to access and vote the form of proxy card.
Q.	Can I vote my shares by filling out and returning the Notice?
A.	No. The Notice identifies the items to be voted on at the Annual Meeting, but you cannot vote by marking the Notice and returning it. The Notice provides instructions on how to vote over the Internet or by telephone, by requesting and returning a printed proxy card, or how to register to vote online during the Annual Meeting.
Q.	What does it mean if I receive more than one Notice?
A.	If you receive more than one Notice, your shares may be registered in more than one name or in different accounts. Please follow the voting instructions on the Notices to ensure that all of your shares are voted.
Q.	What is the purpose of the Annual Meeting?
A.	At the Annual Meeting, stockholders will consider and vote on the following matters:
	(1)	The election of one Class II director, Saraswathy Nochur, Ph. D., to serve for a three-year term expiring at the 2026 annual meeting of stockholders and until her successor has been duly elected and qualified (Proposal No. 1).
	(2)	The approval of an amendment to our Restated Certificate of Incorporation to reflect new Delaware law provisions regarding officer exculpation (Proposal No. 2).


	(3)	The ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2023 (Proposal No. 3).
	(4)	The transaction of any other business that may properly come before the Annual Meeting or any adjournment or postponement thereof.
Q.	Why is the Annual Meeting of stockholders a virtual, online meeting?
A.	The Annual Meeting will be held as a virtual meeting of stockholders where stockholders will participate by accessing a website using the Internet. There will not be a physical meeting location. We believe that hosting a virtual meeting may enable greater stockholder attendance and participation from any location around the world.
Q.	How do I virtually attend the Annual Meeting?
A.	We will host the Annual Meeting exclusively via the Internet at www.proxydocs.com/DBTX. In order to attend the Annual Meeting online, you must register at www.proxydocs.com/DBTX prior to the commencement of the Annual Meeting. Upon completing your registration, you will receive further instructions via email, including a unique link that will allow you access to the Annual Meeting and to vote and submit questions during the Annual Meeting. Please be sure to follow instructions found on your Notice, proxy card and/or voting instruction card and subsequent instructions that will be delivered to you via email. Online registration for the Annual Meeting will begin on or around April 28, 2023.
	The webcast of the Annual Meeting will start at 10:00 a.m., Eastern Time, on June 13, 2023. Instructions on how to attend and participate in the meeting online will be sent to you via email, upon completing your registration.
Q.	Who can vote?
A.	Only stockholders of record at the close of business on April 17, 2023, the record date for the Annual Meeting, are entitled to vote at the Annual Meeting. On this record date, there were 25,014,984 shares of our common stock outstanding. Common stock is our only class of stock outstanding.
Q.	How many votes do I have?
A.	Each share of our common stock that you own as of the record date, April 17, 2023, entitles you to one vote on each matter that is voted on.
Q.	Is my vote important?
A.	Your vote is important no matter how many shares you own. Please take the time to vote. Take a moment to read the instructions, choose the way to vote that is the easiest and most convenient for you and cast your vote as soon as possible.
Q.	How do I vote?
A.	If you are the “record holder” of your shares, meaning that you own your shares in your own name and not through a bank, brokerage firm or other nominee, you may vote:


	(1)	Over the Internet: To vote over the Internet prior to the Annual Meeting, please go to the following website: www.proxypush.com/DBTX, and follow the instructions at that site for submitting your proxy electronically. If you vote over the Internet, you do not need to complete and mail your proxy card or vote your proxy by telephone. Your vote must be received by 9:59 a.m. Eastern Time on June 13, 2023 to be counted.


	(2)	By Telephone: To vote by telephone, please call (866) 506-1262, and follow the instructions provided on the proxy card. If you vote by telephone, you do not need to complete and mail your proxy card or vote your proxy over the Internet. Your vote must be received by 9:59 a.m. Eastern Time on June 13, 2023 to be counted.
	(3)	By Mail: To vote by mail, you must request printed proxy materials, including a proxy card, and complete, sign and date the proxy card and return it promptly in the postage prepaid envelope provided. If you vote by mail, you do not need to vote over the Internet or by telephone. Your proxy card must be received by June 12, 2023 to be counted.
	(4)	Online During the Annual Meeting: You may attend and vote at the Annual Meeting online at www.proxydocs.com/DBTX, where you will be able to vote electronically during the meeting. In order to attend, you must register at www.proxydocs.com/DBTX prior to the commencement of the Annual Meeting. Upon completing your registration, you will receive further instructions via email, including a unique link that will allow you access to the Annual Meeting and to vote during the Annual Meeting. 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 your shares are held in “street name,” meaning they are held for your account by an intermediary, such as a bank, brokerage firm or other nominee, then you are deemed to be the beneficial owner of your shares and the bank, brokerage firm or other nominee that actually holds the shares for you is the record holder and is required to vote the shares it holds on your behalf according to your instructions. The proxy materials, as well as voting and revocation instructions, should have been forwarded to you by the bank, brokerage firm or other nominee that holds your shares. In order to vote your shares, you will need to follow the instructions that your bank, brokerage firm or other nominee provides you. Many brokerage firms solicit voting instructions over the Internet or by telephone.
	You are welcome to virtually attend the Annual Meeting if your shares are held in street name, however, you must register in advance at www.proxydocs.com/DBTX. You must also obtain a legal proxy executed in your favor from the holder of record (i.e., your bank, brokerage firm, or other nominee) to vote shares held in street name during the meeting. A legal proxy is not the form of proxy included with this proxy statement. If you hold your shares in “street name,” you must request a legal proxy from your bank, brokerage firm or other nominee to vote during the Annual Meeting. Further instructions will be provided to you as part of your registration process.


Q.	Can I change my vote?
A.	If you are the “record holder” of your shares, you may revoke your proxy and change your vote by following one of the below procedures:
	(1)	Vote over the Internet or by telephone as instructed above under “Over the Internet” and “By Telephone.” Only your latest Internet or telephone vote is counted. You may not change your vote over the Internet or by telephone after 9:59 a.m. Eastern Time, on June 13, 2023.
	(2)	Sign and complete a new proxy card and send it by mail in the postage prepaid envelope provided. Mediant Communications must receive the proxy card no later than June 12, 2023. Only your latest dated proxy card will be counted.
	(3)	Virtually attend the Annual Meeting online and vote online as instructed above. Attending the Annual Meeting alone will not revoke your Internet vote, telephone vote or proxy submitted by mail, as the case may be.
	(4)	Give our Secretary written notice before the meeting that you want to revoke your proxy. Such written notice should be sent to Decibel Therapeutics, Inc., Attention: Laurence Reid, Chief Executive Officer and Secretary, 1325 Boylston Street, Suite 500, Boston, Massachusetts 02215.
	If your shares are held in “street name,” you may submit new voting instructions with a later date by contacting your bank, brokerage firm or other nominee and following their instructions. You may also vote


	virtually at the Annual Meeting, which will have the effect of revoking any previously submitted voting instructions, if you obtain a legal proxy as described in the answer to the question “How do I vote?” above.
	Attending the Annual Meeting alone will not revoke your proxy.
Q.	Will my shares be voted if I do not return my proxy?
A.	If your shares are registered directly in your name, your shares will not be voted if you do not vote over the Internet, by telephone or by returning your proxy card by mail or online while virtually attending the Annual Meeting. If your shares are held in “street name,” your bank, brokerage firm or other nominee may under certain circumstances vote your shares if you do not return your voting instructions. Banks, brokerage firms and other nominees can vote customers’ unvoted shares on discretionary matters but they will not be allowed to vote your shares with respect to certain non-discretionary items. If you do not return voting instructions to your bank, brokerage firm or other nominee to vote your shares, your bank, brokerage firm or other nominee may, on discretionary matters, either vote your shares or leave your shares unvoted.
	Proposal No. 1, the election of one Class II director, and Proposal No. 2, the approval of an amendment to our Restated Certificate of Incorporation, are not considered discretionary matters. If you do not instruct your bank, brokerage firm or other nominee how to vote with respect to Proposal Nos. 1 and 2, your bank, brokerage firm or other nominee may not vote your shares with respect to such proposals and your shares instead will be counted as “broker non-votes” with respect to such proposals. “Broker non-votes” occur when your bank, brokerage firm or other nominee submits a proxy for your shares (because the bank, brokerage firm or other nominee has received instructions from you on one or more proposals, but not all proposals, or has not received instructions from you but is entitled to vote on a particular “discretionary” matter) but does not indicate a vote for a particular proposal because the bank, brokerage firm or other nominee either does not have the authority to vote on that proposal and has not received voting instructions from you or has discretionary authority but chooses not to exercise it. Proposal No. 3, the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2023, is considered a discretionary matter. If you do not instruct your bank, brokerage firm or other nominee how to vote with respect to this proposal, your bank, brokerage firm or other nominee will be able to vote your shares on this proposal even if it does not receive instructions from you, so long as it holds your shares in its name. We encourage you to provide voting instructions to your bank, brokerage firm or other nominee. This ensures that your shares will be voted at the Annual Meeting according to your instructions. You should receive directions from your bank, brokerage firm or other nominee about how to submit your voting instructions.
Q.	How many shares must be represented to hold the Annual Meeting?
A.	A quorum is needed to hold a valid Annual Meeting. A quorum will be present if the holders of a majority of our shares of common stock issued and outstanding and entitled to vote as of the record date are present at the virtual Annual Meeting either “in person” virtually or as represented by proxy. A majority of our shares of common stock outstanding at the record date must be present virtually or represented by proxy to hold the Annual Meeting. This is called a quorum. For purposes of determining whether a quorum exists, we count as present any shares that are voted over the Internet, by telephone, by mail or virtually at the meeting. Further, for purposes of establishing a quorum, we will count as present shares that a stockholder holds even if the stockholder votes to abstain or only votes on one of the proposals. In addition, we will count as present shares that are counted as broker non-votes. If a quorum is not present, we expect to adjourn the Annual Meeting until we obtain a quorum.
	The presence at the Annual Meeting, “in person” virtually or by proxy, of holders representing a majority of our outstanding common stock as of the record date, April 17, 2023, or approximately 12,507,493 shares, will constitute a quorum at the meeting and permit us to conduct the business of the meeting.


Q.	What vote is required to approve each matter and how are votes counted?
A.	Proposal No. 1—Election of Director
	A nominee will be elected as a director at the Annual Meeting if the nominee receives FOR votes representing a plurality of the votes cast by stockholders entitled to vote at the meeting. You may:
	•	vote FOR the nominee; or
	•	WITHHOLD your vote from the nominee.
	Votes that are withheld and broker-non votes will not be included in the vote tally for the election of the director and will not affect the results of the vote.
	Proposal No. 2—Approval of an Amendment to our Restated Certificate of Incorporation
	The affirmative vote of the holders of shares of common stock representing a majority of the shares of our common stock issued and outstanding is required for the approval of an amendment to our Restated Certificate of Incorporation to reflect new Delaware law provisions regarding officer exculpation. Abstentions and broker non-votes will have the same effect as a vote AGAINST Proposal No. 2.
	Proposal No. 3—Ratification of Appointment of Independent Registered Public Accounting Firm
	The affirmative vote of the holders of shares of common stock representing a majority of the votes cast on the matter is required for the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2023. Abstentions and broker non-votes will not be counted as votes cast on this matter and, as a result, will have no effect on the outcome of Proposal No. 3. Although stockholder approval of our audit committee’s appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2023 is not required, we believe that it is advisable to give stockholders an opportunity to ratify this appointment. If this proposal is not approved at the Annual Meeting, our audit committee will reconsider its appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2023.
Q.	How does the board of directors recommend that I vote on the proposals?
A.	Our board of directors recommends that you vote:
	•	FOR the election of one Class II director, Saraswathy Nochur, Ph. D., to serve for a three-year term expiring at the 2026 annual meeting of stockholders and until her successor is duly elected and qualified;
	•	FOR the approval of an amendment to our Restated Certificate of Incorporation to reflect new Delaware law provisions regarding officer exculpation; and
	•	FOR the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2023.
Q.	Are there other matters to be voted on at the Annual Meeting?
A.	We do not know of any matters that may come before the Annual Meeting other than the election of our Class II director, the approval of an amendment to our Restated Certificate of Incorporation and the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2023. If any other matters are properly presented at the Annual Meeting, shares represented by proxies will be voted in accordance with the best judgment of the persons named in the proxies or their substitutes on the matter.


Q.	Who will count the votes?
A.	The votes will be counted, tabulated and certified by Mediant Communications, Inc.
Q.	How can I find out the results of the voting at the Annual Meeting?
A.	Preliminary voting results will be announced at the Annual Meeting. Final voting results will be tallied by the inspector of election and published in a current report on Form 8-K to be filed with the SEC within four business days after the Annual Meeting.
Q.	How do I submit a question at the Annual Meeting?
A.	If you wish to submit a question prior to the Annual Meeting, you must register to attend the Annual Meeting. You can visit www.proxydocs.com/DBTX and follow the instructions for registering to attend the Annual Meeting and for submitting a question. If you wish to submit a question during the Annual Meeting, you may log into the virtual meeting platform using the unique link provided to you via email following the completion of your registration prior to the commencement of the Annual Meeting at www.proxydocs.com/DBTX. Our virtual meeting will be governed by our Rules of Conduct and Procedures, which will be posted at www.proxydocs.com/DBTX during the meeting.
Q.	How and when may I submit a stockholder proposal, including a stockholder nomination for director for the 2024 annual meeting?
A.	Stockholders wishing to suggest a candidate for director should write to our Secretary. In order to give the nominating and corporate governance committee sufficient time to evaluate a recommended candidate and/or include the candidate in our proxy statement for the 2024 annual meeting, the recommendation should be received by our Secretary at our principal executive offices in accordance with our procedures detailed in the section below entitled “Stockholder Proposals for our 2024 Annual Meeting.” Such submissions must state the nominee’s name, together with appropriate biographical information and background materials and information with respect to the stockholder or group of stockholders making the recommendation, including the number of shares of common stock owned by such stockholder or group of stockholders, as well as other information required by our bylaws or SEC regulations. We may require any proposed nominee to furnish such other information as we may reasonably require in determining the eligibility of such proposed nominee to serve as an independent director or that could be material to a reasonable stockholder’s understanding of the independence, or lack thereof, of such proposed nominee.
Q.	Who is paying the costs of soliciting these proxies?
A.	We will pay all of the costs of soliciting proxies. Our directors, officers and other employees may solicit proxies in person or by mail, telephone, fax or email. We will pay our directors, officers and other employees no additional compensation for these services. We will ask banks, brokerage firms and other nominees to forward these proxy materials to their principals and to obtain authority to execute proxies. We may reimburse them for their expenses.
Q.	Whom should I contact if I have any questions?
A.	If you have any questions about the Annual Meeting or your ownership of our common stock, please contact Decibel Investor Relations at 1325 Boylston Street, Suite 500, Boston, MA 02215, telephone: 617-370-8701, e-mail: info@decibeltx.com.

Implications of Being an “Emerging Growth Company” and a “Smaller Reporting Company”

We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012, or the JOBS Act, and may remain an emerging growth company until December 31, 2026 or until such earlier time as we have more than $1.235 billion in annual revenue, we become a “large accelerated filer” under SEC rules, or we issue more than $1 billion of non-convertible debt over a three-year period. The JOBS Act contains provisions that, among other things, reduce certain reporting requirements for an “emerging growth company.” For so long as we remain an emerging growth company, we are permitted and plan to rely on exemptions from certain disclosure requirements that are applicable to other public companies that are not emerging growth companies. These exemptions include reduced disclosure obligations regarding executive compensation. In addition, as an emerging growth company, we are not required to conduct votes seeking approval, on an advisory basis, of the compensation of our named executive officers or the frequency with which such votes must be conducted. We may take advantage of some or all of these exemptions until such time as we are no longer an emerging growth company. We have taken advantage of certain reduced reporting obligations in this proxy statement.

Accordingly, the information contained herein may be different than the information you receive from other public companies in which you hold stock.

We are also a “smaller reporting company,” meaning that the market value of our stock held by non-affiliates is less than $700 million and our annual revenue was less than $100 million during our most recently completed fiscal year. We may continue to be a smaller reporting company if either (i) the market value of our stock held by non-affiliates is less than $250 million or (ii) our annual revenue was less than $100 million during the most recently completed fiscal year and the market value of our stock held by non-affiliates is less than $700 million.

If we are a smaller reporting company at the time we cease to be an emerging growth company, we may continue to rely on exemptions from certain disclosure requirements that are available to smaller reporting companies. For so long as we remain a smaller reporting company, we are permitted and intend to rely on exemptions from certain disclosure and other requirements that are applicable to other public companies that are not applicable to a smaller reporting company.

In accordance with the terms of our restated certificate of incorporation and amended and restated 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. As a result, only one class of our directors is elected at each annual meeting of stockholders, with the other classes continuing for the remainder of their respective three-year terms. Our board of directors currently consists of eight members. The members of the classes are divided as follows:

•

the class I directors are Alison Finger, M.B.A. and Kevin McLaughlin, M.B.A. and their term will expire at the annual meeting of stockholders to be held in 2025;

•

the class II directors are Neil Exter, M.B.A., Saraswathy Nochur, Ph.D. and Peter A. Thompson, M.D., and their term will expire at the Annual Meeting; and

•

the class III directors are William H. Carson, M.D., Matthew Kapusta, M.B.A., and Laurence Reid, Ph.D., and their term 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 board of directors has nominated Saraswathy Nochur, Ph.D., for election as a class II director at the Annual Meeting. Dr. Nochur is presently a director and has indicated a willingness to continue to serve as director, if elected. Unless otherwise instructed, proxies will be voted for Dr. Nochur. In the event that Dr. Nochur is not a candidate or is unable to serve as a director at the time of the election (which is not currently expected), your proxy will be voted for any nominee who is designated by our board of directors to fill the vacancy.

Our board of directors, upon the recommendation of our nominating and corporate governance committee, determined not to nominate Dr. Thompson and Mr. Exter for re-election at the Annual Meeting.

Recommendation of the Board of Directors

OUR BOARD OF DIRECTORS RECOMMENDS THAT THE STOCKHOLDERS VOTE FOR THE ELECTION OF DR. NOCHUR.

PROPOSAL NO. 2

AMENDMENT OF OUR RESTATED CERTIFICATE OF INCORPORATION TO REFLECT NEW DELAWARE LAW PROVISIONS REGARDING OFFICER EXCULPATION

We are asking stockholders to approve a proposed amendment to our Restated Certificate of Incorporation to update our existing director exculpation provision to include certain of our senior corporate officers. Article Seventh of our Restated Certificate of Incorporation currently provides for exculpation of directors in certain circumstances pursuant to and consistent with Section 102(b)(7) of the Delaware General Corporation Law, or the DGCL. Effective August 1, 2022, that provision of the DGCL was amended to permit eliminating or limiting monetary liability for certain senior corporate officers in limited circumstances.

Our board of directors has unanimously approved and declared advisable the amendment to our Restated Certificate of Incorporation to update the exculpation provision and recommends that stockholders approve this proposed amendment. If the stockholders approve this proposal, we will file a Certificate of Amendment of our Restated Certificate of Incorporation in the form attached hereto as Appendix A adding the new language included below.

Overview of the Proposed Amendment

Consistent with Delaware law, the proposed amendment to our Restated Certificate of Incorporation relating to officers is more limited in scope than the existing director exculpation provision and only permits exculpation of officers for certain direct claims.

Further, the proposed amendment does not permit officers to be exculpated for liability arising out of:

•

claims brought by the Company itself;

•

claims brought by stockholders in the name of the Company (derivative claims);

•

breaches of the duty of loyalty to the Company or its stockholders;

•

acts or omissions not in good faith;

•

acts or omissions that involve intentional misconduct;

•

acts or omissions that involve a knowing violation of law; or

•

any transaction in which the officer derived an improper personal benefit.

In accordance with the recent amendment to Delaware law, the officers who will be covered by the expanded exculpation provision include our president; chief executive officer; chief operating officer; chief financial officer; chief legal officer; controller; treasurer; or chief accounting officer; any officer who is or was identified in the Company’s public filings with the SEC as one of the most highly compensated executive officers; and, any officers who consent to being identified as an officer for purposes of service of process, at any time during the course of conduct alleged in the action or proceeding to be wrongful.

Rationale for the Proposed Amendment

The State of Delaware, which is our state of incorporation, recently enacted legislation that authorizes Delaware corporations to limit the liability of certain of their officers in the limited circumstances described above. As a result of this development, we propose expanding our existing director exculpation provision to cover officers to the extent now permitted by Delaware law.

The rationale of our board of directors for recommending this amendment is to balance stockholders’ interest in accountability with their interest in the Company being able to attract and retain the highest quality officers and avoiding litigation abuse resulting from the current disparity that exists in the treatment of directors, who oversee and are ultimately accountable for corporate actions, and the officers who execute those actions on behalf of our board of directors.

Our board of directors considered that the role of directors and officers requires them to make decisions on crucial matters in response to time-sensitive opportunities and challenges, which can create substantial risk of investigations, claims, actions, suits or proceedings seeking to impose liability on the basis of hindsight, especially in the current litigious environment and regardless of the absence of any underlying merit. This amendment will better align the

protections available to our officers with those currently available to our directors and avoid an emerging practice among plaintiff’s lawyers of adding officers to direct claims relating to the duty of care in M&A-related and other litigation so that claims against the officers continue even when identical claims against directors are dismissed. Our board of directors believes that limiting concern about personal liability will empower officers to best exercise their business judgment in furtherance of stockholder interests without the distraction of potentially being subject to claims following actions taken in good faith.

In addition, we expect other companies with which we compete for employees to adopt exculpation clauses that limit the personal liability of officers as now permitted by the DGCL. Our board of directors believes that failing to adopt the proposed amendment may impact recruitment and retention of exceptional officer candidates who conclude that the potential exposure to liabilities, costs of defense and other risks of proceedings exceeds the benefits of serving as an officer of the Company as compared to serving as an officer at another company that does exculpate officers.

Further, our board of directors noted that the proposed provision would not eliminate stockholders’ right to pursue derivative claims relating to alleged breaches of the duty of care or limit the ability of the Company itself to bring claims against officers. Therefore, taking into account the narrow class and type of claims for which officers’ liability would be exculpated, our board of directors believes the proposed amendment would enhance the ability to attract and retain talented officers, potentially reduce litigation costs associated with frivolous lawsuits, and more generally align the protections available to our officers with those currently available to our directors.

Based on the above, our board of directors has determined that it is in the best interests of the Company and our stockholders to amend the Restated Certificate of Incorporation as described in this proposal.

Text of Proposed Amendment

Accordingly, we ask our stockholders to vote on the following resolution:

“RESOLVED, that the Company’s stockholders approve an amendment to the Company’s Restated Certificate of Incorporation to replace the existing Article Seventh with the following (which is marked to show changes from the current director exculpation provision):

SEVENTH: To the fullest Except to the extent permitted by that the General Corporation Law of the State of Delaware prohibits the elimination or limitation of liability of directors for breaches of fiduciary duty, no director or officer of the Corporation shall be personally liable to the Corporation (in the case of directors) or its stockholders (in the case of directors and officers) for monetary damages for any breach of fiduciary duty as a director or officer, notwithstanding any provision of law imposing such liability. No amendment, repeal or elimination of this provision shall apply to or have any effect on its application with respect to any act or omission of a director or officer occurring before such amendment, repeal or elimination. If the General Corporation Law of the State of Delaware is amended to permit further elimination or limitation of the personal liability of directors or officers, then the liability of a director or officer of the Corporation shall be eliminated or limited to the fullest extent permitted by the General Corporation Law of the State of Delaware as so amended.”

Recommendation of the Board of Directors

OUR Board of directors recommends THAT THE STOCKHOLDERS vote “FOR” the proposal to amend OUR Restated Certificate of Incorporation.

PROPOSAL NO. 3

RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTANTS

The audit committee has appointed Ernst & Young LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2023 and the board of directors has directed that management submit the selection of the independent registered public accountants for ratification by the stockholders at the Annual Meeting. Ernst & Young LLP has served as the Company’s registered public accountant since 2017. A representative of Ernst & Young LLP is expected to be present online at the Annual Meeting and will have an opportunity to make a statement if he or she desires to do so and to respond to appropriate questions from our stockholders.

Stockholder ratification of the appointment of Ernst & Young LLP as the Company’s independent registered public accounting firm is not required by Delaware law, our restated certificate of incorporation or our amended and restated bylaws. However, the board of directors is submitting the audit committee’s 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 a different independent registered public 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 Accountants, Fees and Other Matters

Ernst & Young LLP was our independent registered public accounting firm for the years ended December 31, 2022 and December 31, 2021. The following table summarizes the fees of Ernst & Young LLP billed to us for the last two fiscal years.


	2022		2021
Audit Fees(1)	$	737,000	$	685,800
Audit Related Fees(2)		10,000		—
Tax Fees(3)		20,000		25,000
All Other Fees(4)		2,000		—
Total	$	769,000	$	710,800

(1) “Audit Fees” consist of fees for the audit of our annual consolidated financial statements included in our annual report on Form 10-K, the review of our interim consolidated financial statements included in our quarterly reports on Form 10-Q, services in connection with our registration statement filings and other professional services provided in connection with regulatory filings or engagements.

(2) “Audit Related Fees” consist of services that are reasonably related to the performance of the audit or review of our consolidated financial statements. There were no such fees incurred in 2021.

(3) “Tax Fees” consist of fees for tax advisory services performed by Ernst & Young LLP.

(4) “All Other Fees” consist of fees billed for products and services provided by the independent registered public accounting firm other than those disclosed above. Such fees for 2022 consisted of licensing fees paid to Ernst & Young LLP for access to its proprietary accounting research database. There were no such fees incurred in 2021.

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 such independence.

Pre-Approval Policies and Procedures

Our audit committee has adopted policies and procedures relating to the approval of all audit and other permitted non-audit services provided to us by our independent registered public accounting firm. These policies provide 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 to render the service is

entered into pursuant to the pre-approval procedure. From time to time, our audit committee may pre-approve services that are expected to be provided to us by our independent registered public accounting firm during the next 12 months. These services may include audit services, audit-related services, tax services and other permissible non-audit services. Our independent registered public accounting firm and senior management will periodically report to the audit committee regarding the extent of services provided by our independent registered public accounting firm.

During our 2022 and 2021 fiscal years, no services were provided to us by Ernst & Young LLP other than in accordance with the pre-approval policies and procedures described above.

Recommendation of the Board of Directors

OUR BOARD OF DIRECTORS RECOMMENDS THAT THE STOCKHOLDERS VOTE TO RATIFY THE APPOINTMENT OF ERNST & YOUNG LLP AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE FISCAL YEAR ENDING DECEMBER 31, 2023.

CORPORATE GOVERNANCE

We believe that good corporate governance is important to ensure that our company is managed for the long-term benefit of our stockholders. This section describes key corporate governance practices that we have adopted. Complete copies of our corporate governance guidelines, committee charters and code of business conduct and ethics are available on the “Investors” section of our website, www.decibeltx.com. We will also provide copies of these documents, free of charge, to any stockholder upon written request to Decibel Investor Relations, Decibel Therapeutics, Inc., 1325 Boylston Street, Suite 500, Boston, MA 02215, telephone: 617-370-8701, email: info@decibeltx.com.

Corporate Governance Guidelines

Our board of directors has adopted corporate governance guidelines to assist in the exercise of its duties and responsibilities and to serve the best interests of Decibel and our stockholders. These guidelines, which provide a framework for the conduct of our board’s business, provide that:

•

our board’s principal responsibility is to oversee the management of Decibel;

•

a majority of the members of our board shall be independent directors;

•

the independent directors meet at least twice annually in executive session;

•

directors have full and free access to management and, as necessary and appropriate, independent advisors;

•

new directors participate in an orientation program and all directors are expected to participate in continuing director education on an ongoing basis; and

•

the nominating and corporate governance committee of the board shall oversee an annual self- evaluation of the board to determine whether our board and its committees are functioning effectively.

Director Independence

The rules of the Nasdaq Stock Market, or Nasdaq, require a majority of a listed company’s board of directors to comprise independent directors within one year of listing. In addition, 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. Audit committee members must also satisfy the independence criteria set forth in Rule 10A-3 under the Securities Exchange Act of 1934, as amended, or the Exchange Act, and compensation committee members must also satisfy the 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, 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, accept, directly or indirectly, any consulting, advisory, or other compensatory fee from the listed company or any of its subsidiaries or otherwise 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 must consider, for each member of a compensation 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 committee member, including, but not limited to: (1) the source of compensation of the director, including any consulting advisory or other compensatory fee paid by such company to the director; and (2) whether the director is affiliated with the company or any of its subsidiaries or affiliates.

In April 2023, our board of directors undertook a review of the composition of our board of directors and its committees and the independence of each director. Based upon information requested from and provided by each director concerning his or her background, employment and affiliations, including family relationships, our board of directors has determined that each of our directors, with the exception of Laurence Reid, Ph.D., is an “independent director” as defined under applicable Nasdaq rules, including, in the case of all the members of our audit committee, the independence criteria set forth in Rule 10A-3 under the Exchange Act, and in the case of all the members of our

compensation committee, the independence criteria set forth in Rule 10C-1 under the Exchange Act. In March 2022, our board of directors also previously determined that Matthew Foy, a former director who served during part of the year ended December 31, 2022, was an “independent director” as defined under applicable Nasdaq rules prior to the expiration of his term in June 2022. In making such determinations, our board of directors considered the relationships that each such non-employee director has with our company and all other facts and circumstances that our board of directors deemed relevant in determining his or her independence, including the beneficial ownership of our capital stock by each non-employee director. Dr. Reid is not an independent director under these rules because he is an executive officer of our company.

Board Leadership Structure

Currently, the roles of chairman of our board of directors and chief executive officer are separated. William H. Carson, M.D. is the chairman of our board of directors and Laurence Reid, Ph.D. is our chief executive officer. We believe that separating these positions allows our chief executive officer to focus on our day-to-day business, while allowing our chairman of the board to lead the board of directors in providing advice to, and independent oversight of, our management. While our amended and restated by-laws and corporate governance guidelines do not require that chairman of our board of directors 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.

Board Diversity

In accordance with Nasdaq’s Board Diversity Rule, we have elected to include our board diversity matrix in this proxy statement as set forth below:


Board Diversity Matrix (As of April 28, 2023)

Director Nomination Process

Director Qualifications

While there are no specific minimum qualifications for a committee-recommended nominee to our board of directors, the qualifications, qualities and skills that our nominating and corporate governance committee believes must be met by a committee-recommended nominee for a position on our board of directors are as follows:

•

Nominees should have a reputation for integrity, honesty and adherence to high ethical standards.

•

Nominees should have demonstrated business acumen, experience and ability to exercise sound judgments in matters that relate to the current and long-term objectives of our company and should be willing and able to contribute positively to the decision-making process of our company.

•

Nominees should have a commitment to understand our company and its industry and to regularly attend and participate in meetings of our board of directors and its committees.

•

Nominees should have the interest and ability to understand the sometimes conflicting interests of the various constituencies of our company, which include stockholders, employees, customers, governmental units, creditors and the general public, and to act in the interests of all stockholders.

•

Nominees should have the ability to represent the interests of all the Company’s stockholders and to fulfill the responsibilities of a director.

A Nominees’ background, including prior experience and knowledge of the life sciences industry, and the value of diversity on our board of directors are also considered by the nominating and corporate governance committee when evaluating director nominees. The nominating and corporate governance committee has not adopted a formal policy with respect to diversity, but believes that our board of directors, taken as a whole, should embody a diverse set of skills, experiences and backgrounds. In this regard, the committee takes into consideration the diversity (for example, with respect to gender, race and national origin) of our board members. The nominating and corporate governance committee does not apply any particular weighting of diversity or any other characteristic in evaluating nominees and directors. Nominees are not discriminated against on the basis of race, religion, national origin, sex, sexual orientation, disability or any other basis proscribed by law.

The nominating and corporate governance committee’s goal is to assemble a board of directors that brings to our company a variety of perspectives and skills derived from high quality business and professional experience. Moreover, the nominating and corporate governance committee believes that the background and qualifications of the board of directors, considered as a group, should provide a significant mix of experience, knowledge and abilities that will allow the board of directors to fulfill its responsibilities. Our directors’ performance and qualification criteria are reviewed periodically by the nominating and corporate governance committee.

Identification and Evaluation of Nominees for Directors

The nominating and corporate governance committee is responsible for identifying individuals qualified to serve as directors, and recommending the 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 director candidates. The process followed by the nominating and corporate governance committee to identify and evaluate director candidates includes ongoing assessment of the qualifications of our board of directors relative to the current and projected needs of our company, requests to board members and others for recommendations and meetings from time to time to evaluate biographical information and background material relating to potential candidates. Final candidates, if other than our current directors, 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 judgment. After review and deliberation of all feedback and data, the nominating and corporate governance committee makes its recommendation to our board of directors.

In 2021 and 2022, our nominating and corporate governance committee engaged a third-party search firm to assist in identifying and screening potential director candidates. Each of Dr. Carson, Ms. Finger, and Mr. Kapusta, were identified by the third-party search firm. The nominating and corporate governance committee may in the future continue to use third party search firms in situations where particular qualifications are required or where existing contacts are not sufficient to identify an appropriate candidate.

Stockholders may recommend individuals to our nominating and corporate governance committee for consideration as potential director candidates by submitting their names, together with appropriate biographical information and background materials, a statement as to the number of shares of our common stock beneficially owned by the stockholder making the recommendation, and certain other information as set forth in our amended and restated bylaws, to the Nominating and Corporate Governance Committee, Attention: Laurence Reid, Chief Executive Officer and Secretary, Decibel Therapeutics, Inc., 1325 Boylston Street, Suite 500, Boston, MA 02215. Assuming that appropriate biographical and background material has been provided on or before the dates set forth in the section below entitled “Stockholder Proposals for our 2024 Annual Meeting,” the committee will evaluate

stockholder-recommended candidates by following substantially the same process, and applying substantially the same criteria, as it follows for candidates submitted by others, as described above. If the board of directors determines to nominate a stockholder-recommended candidate and recommends his or her election, then his or her name will be included in our proxy card for the next annual meeting. Stockholders also have the right under our amended and restated bylaws to directly nominate director candidates, without any action or recommendation on the part of the nominating and corporate governance committee or our board of directors, by following the procedures set forth under “Stockholder Proposals for our 2024 Annual Meeting.”

Communications with Our Board of Directors

Our board of directors will give appropriate attention to written communications that are submitted by stockholders and will respond if and as appropriate. 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, or otherwise the chair of the nominating and corporate governance committee, by submitting a written communication to the attention of such director at the following address: Decibel Therapeutics, Inc., 1325 Boylston Street, Suite 500, Boston, MA 02215.

Communications are forwarded to all directors if they relate to important substantive matters and include suggestions or comments that the chairman of our board of directors or the chair of the nominating and corporate governance committee, as applicable, considers to be important for the directors to know. In general, communications relating to corporate governance and corporate strategy are more likely to be forwarded than communications relating to ordinary business affairs, personal grievances and matters as to which we receive repetitive or duplicative communications.

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

The audit committee oversees the procedures for the receipt, retention, and treatment of complaints received by us 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. We have also established a toll-free telephone number for the reporting of such activity, which is 877-653-4399, and a secure web form available at www.whistleblowerservices.com/DBTX.

Our board of directors met twelve times during the year ended December 31, 2022, including telephonic meetings. During the year, each of our directors attended 75% or more of the aggregate number of meetings of the board of directors and the committees on which he or she served.

Director Attendance at Annual Meeting

Our corporate governance guidelines provide that directors are expected to attend the annual meeting of stockholders. Each then-serving member of our board of directors, other than Mr. Foy, who did not stand for re-election at the 2022 annual meeting of stockholders, attended our 2022 annual meeting of stockholders.

Committees of Our Board of Directors

Our board of directors has established an audit committee, a compensation committee and a nominating and corporate governance committee, each of which operate under a charter approved by our board of directors. Each committee’s charter is posted on the “Investors” section of our website, www.decibeltx.com.

Audit Committee

Our audit committee held four meetings during 2022. The members of our audit committee are Neil Exter, M.B.A., Alison Finger, M.B.A. and Kevin McLaughlin, M.B.A., and Mr. McLaughlin is the chair of the audit committee.

Mr. Exter served as the chair of the audit committee until Mr. McLaughlin was elected to and named chair of the audit committee in October 2022. Our board of directors has determined that each of Mr. McLaughlin and Mr. Exter is an “audit committee financial expert” as defined by applicable SEC rules and that each of the members of our audit committee possesses the financial sophistication required for audit committee members under Nasdaq rules. We believe that the composition of our audit committee meets the requirements for independence under current Nasdaq and SEC rules and regulations. Our audit committee’s responsibilities include:

Thompson, M.D., and Dr. Thompson is the chair of the compensation committee. Kevin McLaughlin was elected to the compensation committee in October 2022. We believe that the composition of our compensation committee meets the requirements for independence under current Nasdaq and SEC rules and regulations.

Nominating and Corporate Governance Committee

Our nominating and corporate governance committee held three meetings during 2022. The members of our nominating and corporate governance committee are Alison Finger, M.B.A., Saraswathy Nochur, Ph.D., and Peter A. Thompson, M.D., and Ms. Finger is the chair of the nominating and corporate governance committee. Matthew Foy served as a member and chair of the nominating and corporate governance committee until the expiration of his term on our board of directors in June 2022. Ms. Finger and Dr. Nochur were elected to the nominating and corporate governance committee, with Ms. Finger as chair, beginning in June 2022. We believe that the composition of our nominating and corporate governance committee meets the requirements for independence under current Nasdaq and SEC rules and regulations. Our nominating and corporate governance committee’s responsibilities include:

•

recommending to our board of directors the persons to be nominated for election as directors and to each of our board’s committees;

•

reviewing the composition of each committee and making recommendations to our board for changes or rotation of committee members, the creation of additional committees and any changes to committee charter;

reviewing and making recommendations to our board with respect to our board leadership structure;

•

developing and recommending to our board of directors corporate governance principles; and

•

overseeing a periodic evaluation of our board of directors.

Board’s Role in Risk Oversight

One of the key functions of our board of directors is informed oversight of our risk management process. Risk is inherent with every business and how well a business manages risk can ultimately determine its success. We face a number of risks, including those described under the caption “Risk Factors” in our 2022 Annual Report. Our board of directors is actively involved in oversight of risks that could affect us. This oversight is conducted primarily by our full board of directors, which has responsibility for general oversight of risks. Our board of directors oversees our risk management processes directly and through its committees, which address risks inherent in their respective areas of oversight. Our risk management processes are intended to identify, manage and control risks so that they are appropriate considering our scope, operations and business objectives. Our management is responsible for risk management on a day-to-day basis, and our board and its committees oversee the risk management activities of management. Our board of directors encourages management to promote a culture that incorporates risk management into our corporate strategy and day-to-day business operations. Management discusses strategic and operational risks at regular management meetings and conducts specific strategic planning and review sessions during the year that include a focused discussion and analysis of the risks facing us.

Our board of directors satisfies its risk oversight responsibility through full reports by each committee chair regarding the committee’s considerations and actions, as well as through regular reports directly from officers responsible for oversight of particular risks within our company. This enables our board of directors to coordinate risk oversight, particularly with respect to interrelated or cumulative risks that may involve multiple areas for which more than one committee may have responsibility.

Our audit committee oversees risk management activities related to financial and information technology controls and legal and compliance risks. This includes a formal annual risk assessment process as well as ongoing assessment of relevant risks based upon changes in the industry and overall business environment. Our compensation committee oversees risk management activities relating to our compensation policies and practices. Our nominating and corporate governance committee oversees risk management activities relating to board composition and management succession planning. In addition, members of our senior management team attend our regular board meetings and are available to address any questions or concerns raised by the board on risk management and any other matters. We also engage outside advisors and experts to assist in the risk assessment process, to provide information to inform decision making and to identify trends and changes in the industry and overall business environment. Our board of directors believes that full and open communication between management and the board of directors is essential for effective risk management and oversight.

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 persons performing similar functions. This code is available on the “Investors” section of our website, www.decibeltx.com. 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.

Anti-Hedging Policy

We have adopted an insider trading policy that, among other things, expressly prohibits all of our employees, including our named executive officers, and directors, as well as certain of their family members and related entities, from engaging in short sales of our securities, including short sales “against the box”; purchases or sales of puts, calls or other derivative securities based on our securities; and purchases of financial instruments (including prepaid variable forward contracts, equity swaps, collars and exchange funds) or other transactions that are designed to hedge or offset any decrease in the market value of our securities.

Director Compensation

The amounts reported represent the aggregate grant date fair value of stock options awarded in 2022, calculated in accordance with Financial Accounting Standard Board, or FASB, Accounting Standards Codification, or ASC, Topic 718. The assumptions used in calculating the grant date fair value are set forth in Note 11 to our audited financial statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022. These amounts reflect the accounting cost for these stock options and do not reflect the actual economic value that may be realized by the directors upon the vesting of the stock options, the exercise of the stock options or the sale of the common stock underlying such stock options. Unless otherwise specified, these awards were granted pursuant to our non-employee director compensation program, whereby each non-employee director who was serving at the time of our 2022 annual meeting of stockholders was granted a stock option award to purchase 10,000 shares of our common stock that vests in full on the one year anniversary of the date of grant, subject to the non-employee director’s continued service as a director, employee or consultant.

As of December 31, 2022, Dr. Carson held unexercised options to purchase 30,000 shares of our common stock, of which 10,000 shares were vested.

Mr. McLaughlin was elected to our board of directors in October 2022 and, upon his election, he was granted a stock option award pursuant to our non-employee director compensation program to purchase 20,000 shares of our common stock that vests in equal monthly installments until the third anniversary of the grant date, subject to his continued service as a director, employee or consultant. As of December 31, 2022, Mr. McLaughlin held unexercised options to purchase 20,000 shares of our common stock, of which 1,111 shares were vested.

Non-Employee Director Compensation Program

In January 2021, our board of directors approved a non-employee director compensation program, which program was in effect for 2022. In February 2023, our compensation committee amended the non-employee director compensation program effective January 1, 2023. The non-employee director compensation program is designed to enable us to attract and retain, on a long-term basis, highly qualified non-employee directors. Under our non-employee director compensation program, we pay our non-employee directors a cash retainer for service on the board of directors and for service on each committee on which the director is a member. The chairman of the board and the chair of each committee receives higher retainers for such service. These fees are payable in arrears in four equal quarterly installments on the last day of each quarter, provided that the amount of such payment is prorated for any portion of such quarter that the director is not serving on our board of directors.

2022 Non-Employee Director Compensation Program

Under our non-employee director compensation program for 2022, 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 were as follows:


	Member Annual Fee		Chair Incremental Annual Fee
Board of Directors	$	35,000	$	30,000
Audit Committee	$	7,500	$	7,500
Compensation Committee	$	5,000	$	5,000
Nominating and Corporate Governance Committee	$	4,000	$	4,000

We also reimburse our non-employee directors for reasonable travel and other expenses incurred in connection with attending meetings of our board of directors and any committee of our board of directors on which he or she serves.

In addition, in 2022 each of our non-employee directors received an option to purchase 20,000 shares of our common stock under our 2021 Stock Incentive Plan, or the 2021 Plan, upon his or her initial election or appointment to our board of directors. Each of these options vests in equal monthly installments until the third anniversary of the grant date, subject to the non-employee director’s continued service as a director, employee or consultant. Further, on the dates of each of our annual meetings of stockholders, each non-employee director that has served on our board of directors for at least six months received, under the 2021 Plan, an option to purchase 10,000 shares of our common stock. Each of these options vest in full on the anniversary of the grant date (or, if earlier, the date of the next annual meeting of stockholders following the date of grant), subject to the non-employee director’s continued service as a director, employee or consultant.

All options issued to our non-employee directors under our director compensation program are issued at exercise prices equal to the fair market value of our common stock on the date of grant and have a term of ten years.

Non-Employee Director Compensation Program, Effective January 1, 2023

For the amended non-employee director compensation program, effective January 1, 2023, the member annual fee for each director was increased to $40,000. All other cash fees remained consistent with the non-employee director compensation program in effect for 2022 described in the table above.

In addition, under the amended non-employee director compensation program effective January 1, 2023, (i) the grant to each non-employee director upon initial election to our board of directors is an option to purchase 10,000 shares of our common stock and a restricted stock unit for 10,000 shares of our common stock; and (ii) the annual grant to each non-employee director that has served on our board of directors for at least six months is an option to purchase 5,000 shares of our common stock and a restricted stock unit for 5,000 shares of our common stock. Subject to the non-employee director’s continued service as a director, the initial option grant will vest in equal monthly installments until the third anniversary of the grant date and the initial restricted stock unit grant will vest in annual installments until the third anniversary of the grant date and, in the event of a change in control, the vesting schedule of the option and the restricted stock unit will accelerate in full. In addition, subject to the non-employee director’s continued service as a director, the annual option grant and the annual restricted stock unit grant each will vest in full on the first anniversary of the grant date (or, if earlier, the date of the next annual meeting of stockholders following the date of grant) and, in the event of a change in control, the vesting schedule of the option and the restricted stock unit will accelerate in full.

Rule 10b5-1 Sales Plans

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

Limitation of Liability and Indemnification

Our restated certificate of incorporation limits the personal liability of our directors for breach of fiduciary duty to the maximum extent permitted by the Delaware General Corporation Law, or the DGCL, and provides that no director will have personal liability to us or to our stockholders for monetary damages for breach of fiduciary duty as a director. However, these provisions do not eliminate or limit the liability of any of our directors:

•

for any breach of the director’s duty of loyalty to us or our stockholders;

•

for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law;

•

for voting for or assenting to unlawful payments of dividends, stock repurchases or other distributions; or

•

for any transaction from which the director derived an improper personal benefit.

Any amendment to or repeal of these provisions will not eliminate or reduce the effect of these provisions in respect of any act, omission or claim that occurred or arose prior to such amendment or repeal. If the DGCL is amended to provide for further limitations on the personal liability of directors of corporations, then the personal liability of our directors will be further limited to the greatest extent permitted by the DGCL.

In addition, our restated certificate of incorporation provides that we must indemnify our directors and officers and we must advance expenses, including attorneys’ fees, to our directors and officers in connection with legal proceedings, subject to very limited exceptions.

We maintain a general liability insurance policy that covers specified liabilities of our directors and officers arising out of claims based on acts or omissions in their capacities as directors or officers. In addition, we have entered into indemnification agreements with all of our directors and executive officers. These indemnification agreements may require us, among other things, to indemnify each such executive officer or director for some expenses, including attorneys’ fees, judgments, fines and settlement amounts incurred by him or her in any action or proceeding arising out of his or her service as one of our executive officers or directors.

Some of our non-employee directors may, through their relationships with their employers, be insured or indemnified against specified liabilities incurred in their capacities as members of our board of directors.

Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended, or the Securities Act, may be permitted to directors, executive officers or persons controlling us, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

Report of the Audit Committee of the Board of Directors

The audit committee oversees the Company’s financial reporting process on behalf of the board of directors. We have reviewed the Company’s audited consolidated financial statements for the year ended December 31, 2022 and discussed them with Company management and Ernst & Young LLP, the Company’s independent registered public accounting firm.

We have received from, and discussed with, Ernst & Young LLP, which is responsible for expressing an opinion on the conformity of the Company’s audited consolidated financial statements with accounting principles generally accepted in the United States such matters as are required to be discussed with the audit committee under generally accepted auditing standards, including the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board, or the PCAOB, and the SEC. In addition, we have received from Ernst & Young LLP the written disclosures and the letter required by applicable requirements of the PCAOB regarding its communications with us concerning independence and have discussed with Ernst & Young LLP its independence from management and the Company.

Based on the review and discussions referred to above, we recommended to the board of directors that the audited consolidated financial statements be included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022.

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 or the Exchange Act, 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

Kevin McLaughlin, M.B.A., Chair

Neil Exter, M.B.A.

Alison Finger, M.B.A.
