PROXY STATEMENT

FOR THE 2024 ANNUAL MEETING OF STOCKHOLDERS

QUESTIONS AND ANSWERS ABOUT THESE PROXY MATERIALS AND VOTING

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

Pursuant to “Notice and Access” rules adopted by the Securities and Exchange Commission (the “SEC”), we have elected to provide access to our proxy materials over the internet. Accordingly, we are sending an Important Notice Regarding the Availability of Proxy Materials (the “Proxy Availability Notice”) to our stockholders of record. All stockholders will have the ability to access the proxy materials on the website referred to in the Proxy Availability Notice free of charge or request to receive a printed set of the proxy materials for the Annual Meeting. Instructions on how to access the proxy materials over the internet or to request a printed copy may be found in the Proxy Availability Notice.

We provided some of our stockholders, including stockholders who have previously requested to receive paper copies of the proxy materials and some of our stockholders who are participants in our benefit plans, with paper copies of the proxy materials instead of the Proxy Availability Notice. If you received paper copies of the proxy materials, we encourage you to help us save money and reduce the environmental impact of delivering paper proxy materials to stockholders by signing up to receive all of your future proxy materials electronically.

We expect that this Proxy Statement and the other proxy materials will be available to stockholders on or about April 25, 2024.

Why are you having a virtual annual meeting?

The Annual Meeting will be held in a virtual-only meeting format, via live video webcast that will provide stockholders with the ability to participate in the Annual Meeting, vote their shares and ask questions. We believe that a virtual meeting will enable expanded access, thus increasing stockholder attendance and participation, in addition to reducing the costs to stockholders associated with holding an in-person meeting.

How can I attend the virtual annual meeting?

The Annual Meeting will be held on June 13, 2024 at 8:00 a.m. (Pacific Time) via live video webcast.

Only stockholders of record and beneficial owners of shares of our common stock as of the close of business on April 15, 2024, the Record Date, may participate in the virtual Annual Meeting, including voting and asking questions during the Annual Meeting. You will not be able to attend the Annual Meeting physically in person.

In order to attend the Annual Meeting, you must register at www.proxydocs.com/AFIB. 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. Whether or not you plan to attend the Annual Meeting, we urge you to vote and submit your proxy in advance of the meeting by one of the methods described in these proxy materials.

As part of the registration process, you must enter the control number located on your proxy card, voting instruction form, or Proxy Availability Notice. If you are a beneficial owner of shares registered in the name of a broker, bank or other nominee, you will also need to provide the registered name on your account and the name of your broker, bank or other nominee as part of the registration process.

1

On the day of the Annual Meeting, June 13, 2024, stockholders may begin to log in to the virtual-only Annual Meeting 15 minutes prior to the Annual Meeting. The Annual Meeting will begin promptly at 8:00 a.m. Pacific Time.

Can I ask questions at the virtual Annual Meeting?

Stockholders of record and beneficial owners of our common stock as of our Record Date who attend and participate in our virtual Annual Meeting will have an opportunity to submit questions live via the internet during a designated portion of the meeting. These stockholders may also submit a question in advance of the Annual Meeting by registering at www.proxydocs.com/AFIB. In both cases, stockholders must have available their control number provided on their proxy card, voting instruction form or Proxy Availability Notice.

What does it mean if I receive more than one Proxy Availability Notice?

If you receive more than one Proxy Availability Notice, your shares may be registered in more than one name or in different accounts. Please follow the voting instructions on each Proxy Availability Notice to ensure that all of your shares are voted.

Will I receive any other proxy materials by mail?

We may send you a proxy card, along with a second Proxy Availability Notice, by mail on or after April 25, 2024.

Who can vote at the Annual Meeting?

Only stockholders of record at the close of business on the Record Date of April 15, 2024 will be entitled to vote at the Annual Meeting. On the Record Date, there were 29,721,542 shares of common stock outstanding and entitled to vote.

Stockholder of Record: Shares Registered in Your Name

If, on April 15, 2024, your shares were registered directly in your name with Acutus’ transfer agent, Computershare Trust Company, N.A. (“Computershare”), then you are a stockholder of record. As a stockholder of record, you may vote at the Annual Meeting or vote by proxy.

Whether or not you plan to attend the Annual Meeting, we urge you to vote by proxy over the telephone or on the internet as instructed below (see “How do I vote?”) or complete, date, sign and return the proxy card mailed to you to ensure your vote is counted.

Beneficial Owner: Shares Registered in the Name of a Broker, Bank or Other Nominee

If, on April 15, 2024, your shares were held, not in your name, but rather in an account at a brokerage firm, bank, dealer or other similar organization, then you are the beneficial owner of shares held in “street name” and the Proxy Availability Notice is being forwarded to you by the organization that holds your account. The organization holding your account is considered to be the stockholder of record for purposes of voting at the Annual Meeting. As a beneficial owner, you have the right to direct your broker, bank or other nominee regarding how to vote the shares in your account. You are also invited to attend the Annual Meeting. However, since you are not the stockholder of record, you may not vote your shares at the Annual Meeting unless you request and obtain a valid proxy from your broker, bank or other nominee.

What am I voting on?

There are two matters scheduled for a vote:

2

What if another matter is properly brought before the Annual Meeting?

The Board knows of no other matters that will be presented for consideration at the Annual Meeting. If any other matters are properly brought before the Annual Meeting, the persons named in the accompanying proxy will vote the shares for which you grant your proxy on those matters in accordance with their best judgment.

What is the Board’s voting recommendation?

The Board recommends that you vote your shares:

How do I vote?

Regarding the election of directors, you may either vote “For” the nominees to the Board or you may “Withhold” your vote for any nominee you specify or for all nominees. For any other matters to be voted on, you may vote “For” or “Against” or abstain from voting.

The procedures for voting depend on whether your shares are registered in your name or are held by a broker, bank or other nominee:

Stockholder of Record: Shares Registered in Your Name

If you are a stockholder of record, you may vote at the Annual Meeting, vote by proxy over the telephone, vote by proxy through the internet, or vote by proxy using a proxy card that you may request or that we may elect to deliver at a later time.

Whether or not you plan to attend the Annual Meeting, we urge you to vote by proxy to ensure your vote is counted. You may still attend the Annual Meeting and vote even if you have already voted by proxy. Voting at the Annual Meeting will have the effect of revoking your previously submitted proxy (see “Can I change my vote after submitting my proxy?” below).

3

Beneficial Owner: Shares Registered in the Name of a Broker, Bank or Other Nominee

If you are a beneficial owner of shares registered in the name of your broker, bank or other nominee, you should have received a Proxy Availability Notice containing voting instructions from that organization rather than from Acutus. Simply follow the voting instructions in the Proxy Availability Notice to ensure that your vote is counted. To vote at the Annual Meeting, you may be required to obtain a valid proxy from your broker, bank or other nominee. Follow the instructions from your broker, bank or other nominee included with these proxy materials, or contact your broker, bank or other nominee to request a proxy form.

How many votes do I have?

On each matter to be voted upon, you have one vote for each share of common stock you own as of April 15, 2024, the Record Date.

What if I return a proxy card or otherwise vote but do not make specific choices?

If you return a signed and dated proxy card or otherwise vote without marking voting selections, your shares will be voted, as applicable, “For” the election of each of the nominees for Class I director and “For” the ratification of KPMG as the Company’s independent registered public accounting firm. If any other matter is properly presented at the Annual Meeting, your proxy holder (one of the individuals named on your proxy card) will vote your shares using his or her best judgment.

Will my vote be kept confidential?

Proxies, ballots and voting tabulations are handled on a confidential basis to protect your voting privacy. This information will not be disclosed, except as required by law.

Who is paying for this proxy solicitation?

The accompanying proxy is solicited on behalf of the Board for use at the Annual Meeting. Accordingly, the Company will pay for the entire cost of soliciting proxies. In addition to these proxy materials, our directors and employees may also solicit proxies in person, by telephone or by other means of communication. Directors and employees of the Company will not be paid any additional compensation for soliciting proxies. We may also reimburse brokerage firms, banks and other nominees for the cost of forwarding proxy materials to beneficial owners.

Can I change my vote after submitting my proxy?

Yes. You can revoke your proxy at any time before the final vote at the Annual Meeting. If you are the record holder of your shares, you may revoke your proxy in any one of the following ways:

4

Your most current proxy card or telephone or internet proxy is the one that is counted, so long as it is provided within the applicable deadline. If your shares are held by your broker, bank or other nominee, you should follow the instructions provided by your broker, bank or other nominee to change your vote or revoke your proxy.

When are stockholder proposals for inclusion in our proxy statement for next year’s annual meeting due?

Stockholders wishing to present proposals for inclusion in our proxy statement for the 2025 annual meeting of stockholders (the “2025 Annual Meeting”) pursuant to Rule 14a-8 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), must submit their proposals so that they are received by us at our principal executive offices no later than December 26, 2024, unless the date of the 2025 Annual Meeting is more than 30 days before or more than 30 days after June 13, 2025, in which case the proposals must be submitted so that they are received by us a reasonable time before we begin to print and send our proxy materials for the 2025 Annual Meeting. Proposals should be sent to our Chief Executive Officer at 2210 Faraday Ave., Suite 100, Carlsbad, CA 92008.

When are other proposals and stockholder nominations for the 2025 Annual Meeting due?

With respect to proposals and nominations not to be included in our proxy statement pursuant to Rule 14a-8 of the Exchange Act, our amended and restated bylaws (our “Bylaws”) provide that stockholders who wish to nominate a director or propose other business to be brought before the stockholders at an annual meeting of stockholders must notify our Chief Executive Officer by a written notice, which notice must be received at our principal executive offices not less than 90 days nor more than 120 days prior to the anniversary date of the immediately preceding year’s annual meeting of stockholders.

Stockholders wishing to present nominations for director or proposals for consideration at the 2025 Annual Meeting under these provisions of our Bylaws must submit their nominations or proposals so that they are received at our principal executive offices not earlier than February 13, 2025 and not later than March 15, 2025 in order to be considered. In the event that the 2025 Annual Meeting is to be held on a date that is not within 30 days before or 70 days after the one-year anniversary of the Annual Meeting, then a stockholder’s notice must be received by the Chief Executive Officer no earlier than 120 days prior to such annual meeting and no later than the later of 70 days prior to the date of the meeting or the tenth day following the day on which we make a public announcement of the date of the 2025 Annual Meeting. In addition to satisfying the requirements under our Bylaws, to comply with the universal proxy rules under the Exchange Act, stockholders who intend to solicit proxies in support of director nominees other than the Company’s nominees must provide notice that sets forth the information required by Rule 14a-19 under the Exchange Act, no later than April 14, 2025. Stockholders must also comply with all applicable requirements of the Exchange Act (including Rule 14a-19(b)) with respect to the solicitation of proxies in support of director nominees other than the Company’s nominees.

Nominations or proposals should be sent in writing to our Chief Executive Officer at 2210 Faraday Ave., Suite 100, Carlsbad, CA 92008. A stockholder’s notice to nominate a director or bring any other business before the Annual Meeting or the 2025 Annual Meeting must set forth certain information, which is specified in our Bylaws. A complete copy of our Bylaws may be found in the Corporate Governance section of the Investors section of our website at www.acutusmedical.com. Information on or accessible through our website is not incorporated by reference in this Proxy Statement.

How are votes counted?

Votes will be counted by the inspector of election appointed for the Annual Meeting, who will separately count votes “For,” votes to “Withhold” and broker non-votes for the proposal to elect directors and, with respect to other proposals, votes “For,” votes “Against,” votes to “Abstain” and broker non-votes (if applicable).

5

What are “broker non-votes”?

Broker non-votes occur when a beneficial owner of shares held in “street name” does not give instructions to the broker, bank or other nominee holding the shares as to how to vote. Generally, if shares are held in street name, the beneficial owner of the shares is entitled to give voting instructions to the broker, bank or other nominee holding the shares. If the beneficial owner does not provide voting instructions, the broker, bank or other nominee can still vote the shares with respect to matters that are considered to be “routine,” but cannot vote the shares with respect to “non-routine” matters. Under the rules and interpretations of The Nasdaq Stock Market LLC (“Nasdaq”), which generally apply to all brokers, banks or other nominees, on voting matters characterized by Nasdaq as “routine,” Nasdaq member firms have the discretionary authority to vote shares for which their customers do not provide voting instructions. On non-routine proposals, such “uninstructed shares” may not be voted by member firms. Only the proposal to ratify the selection of our independent registered public accounting firm is considered a “routine” matter for this purpose and brokers, banks or other nominees generally have discretionary voting power with respect to such proposal. Broker non-votes will be counted for the purpose of determining whether a quorum is present at the Annual Meeting.

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

Abstentions: Under Delaware law (under which Acutus is incorporated), abstentions are counted as shares present and entitled to vote at the Annual Meeting, but they are not counted as shares cast. Our Bylaws provide that, except as otherwise required by law or our certificate of incorporation, a stockholder action (other than the election of directors) shall be decided by the vote of the holders of a majority of the total number of votes of the Company’s capital stock cast on the matter. Therefore, abstentions will have no effect on Proposal No. 2: Ratification of the Selection of the Independent Registered Public Accounting Firm for Acutus.

Votes to Withhold: For Proposal No. 1: Election of Directors, you may vote “For” all or some of the nominees or you may “Withhold” your vote with respect to one or more of the nominees. The two nominees who receive the most “For” votes cast by the holders of shares either present at the Annual Meeting or represented by proxy will be elected to our Board. In an uncontested election, “Withhold” votes will not prevent a candidate from getting elected. Notwithstanding the forgoing, if an incumbent director nominee fails to receive a majority of the votes cast in an election, the director shall immediately tender his or her resignation to the Board. The Nominating and Corporate Governance Committee of the Board will make a recommendation to the Board as to whether to accept or reject the resignation of such incumbent director, or whether other action should be taken (the “Director Resignation Policy”).

Broker Non-Votes: A “broker non-vote” occurs when a broker, bank or other nominee holding your shares in street name does not vote on a particular matter because you did not provide the broker, bank or other nominee voting instructions and the broker, bank or other nominee lacks discretionary voting authority to vote the shares because the matter is considered “non-routine” under Nasdaq rules. The only “non-routine” matter on the agenda for the Annual Meeting is Proposal No. 1: Election of Directors.

Broker non-votes will be counted for the purpose of determining whether a quorum is present at the Annual Meeting. However, because broker non-votes are not considered under Delaware law to be entitled to vote at the Annual Meeting, they will have no effect on the outcome of the vote on Proposal No. 1: Election of Directors. As a result, if you hold your shares in street name and you do not instruct your broker, bank or other nominee how to vote your shares in the election of directors, no votes will be cast on your behalf on that proposal. Therefore, it is critical that you indicate your vote on this proposal if you want your vote to be counted. The proposal to ratify the selection by the Board of KPMG as our independent registered public accounting firm for the fiscal year ending December 31, 2024 should be considered a “routine” matter. Therefore, your broker, bank or other nominee will be able to vote on Proposal No. 2: Ratification of the Selection by the Board of the Independent Registered Public Accounting Firm for Acutus even if it does not receive instructions from you, so long as it holds your shares in its name.

6

How many votes are needed to approve each proposal?

A “Plurality,” with regard to the election of directors, means that the two nominees who receive the most “For” votes cast by the holders of shares either present at the Annual Meeting or represented by proxy will be elected to our Board. A “Majority Cast,” with regard to the ratification of the selection by the Board of our independent registered public accounting firm, means that a majority of the votes cast on the proposal are voted “For” the proposal.

Accordingly:

None of the proposals, if approved, entitles stockholders to appraisal rights under Delaware law or our amended and restated certificate of incorporation.

What is the quorum requirement?

A quorum of stockholders is necessary to hold a valid stockholder meeting. A quorum will be present if stockholders holding at least a majority of the outstanding shares entitled to vote are present or represented by proxy at the Annual Meeting. On the Record Date, there were 29,721,542 shares outstanding and entitled to vote. Thus, the holders of at least 14,860,772 shares must be present or represented by proxy at the Annual Meeting to have a quorum. Virtual attendance at our Annual Meeting constitutes “presence” for purposes of a quorum at the meeting.

Your shares will be counted towards the quorum only if you submit a valid proxy by mail, over the phone or through the internet (or one is submitted on your behalf by your broker, bank or other nominee) or if you vote at the Annual Meeting. Abstentions, votes to “Withhold” and broker non-votes will be counted towards the quorum requirement. If there is no quorum, then either the chair of the Annual Meeting or the holders of a majority of shares present at the Annual Meeting or represented by proxy may adjourn the meeting to another date. At any adjourned Annual Meeting at which a quorum is present, any business may be transacted that might have been transacted at the Annual Meeting as originally notified. If the adjournment is for more than 30 days, or if after that adjournment a new record date is fixed for the adjourned Annual Meeting, a notice of the adjourned Annual Meeting shall be given to each stockholder of record entitled to vote at the adjourned Annual Meeting.

How can I find out the results of the voting at the Annual Meeting?

Preliminary voting results will be announced at the Annual Meeting. In addition, final voting results will be published in a Current Report on Form 8-K that we expect to file with the SEC within four business days after

7

the Annual Meeting. If final voting results are not available to us in time to file a Form 8-K with the SEC within four business days after the Annual Meeting, we intend to file a Form 8-K to publish the preliminary results within four business days after the Annual Meeting and file an additional Form 8-K to publish the final results within four business days after the final results are known to us.

If you have any questions or need assistance in voting your shares, please write to Acutus Investor Relations at investors@acutus.com.

JOBS Act Explanatory Note

We are an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”).

For as long as we continue to be an emerging growth company, we may take advantage of exemptions from various reporting requirements that are applicable to other public companies but not to “emerging growth companies,” including, but not limited to:

We will remain an emerging growth company until the earliest of (i) December 31, 2025; (ii) the last day of the first fiscal year in which our annual gross revenues exceed $1.235 billion, (iii) the date that we become a “large accelerated filer” as defined in Rule 12b-2 under the Exchange Act, which would occur at the end of the fiscal year during which the market value of our common stock held by non-affiliates exceeds $700.0 million as of the last business day of our most recently completed second fiscal quarter of such year, or (iv) the date on which we have issued more than $1.0 billion in non-convertible debt during the preceding three-year period. Under Section 107(b) of the JOBS Act, emerging growth companies may delay adopting new or revised accounting standards until such time as those standards apply to private companies. We have elected to avail ourselves of this provision of the JOBS Act. As a result, we will not be subject to new or revised accounting standards at the same time as other public companies that are not emerging growth companies. Therefore, our consolidated financial statements may not be comparable to those of companies that comply with new or revised accounting pronouncements as of public company effective dates.

We are also a “smaller reporting company” as defined in the Exchange Act. We may continue to be a smaller reporting company even after we are no longer an emerging growth company. We may take advantage of certain of the scaled disclosures available to smaller reporting companies and will be able to take advantage of these scaled disclosures for so long as our voting and non-voting common stock held by non-affiliates is less than $250.0 million measured on the last business day of our second fiscal quarter, or our annual revenue is less than $100.0 million during the most recently completed fiscal year and our voting and non-voting common stock held by non-affiliates is less than $700.0 million measured on the last business day of our second fiscal quarter.

Because we have elected to take advantage of certain reduced disclosure obligations and may elect to take advantage of other reduced reporting requirements in future filings, the information that we provide to our stockholders may be different than you might receive from other public reporting companies in which you hold equity interests.

INTEREST OF CERTAIN PERSONS IN MATTERS TO BE ACTED UPON

The Board of Directors knows of no matters to come before the Annual Meeting other than the matters referred to in this Proxy Statement. No director, nominee for election as director, or executive officer of Acutus has any special interest in any matter to be voted upon other than, in the case of our director nominees, their election to the Board of Directors. However, if any other matters should properly come before the meeting, the persons named in the enclosed proxy intend to vote in accordance with their best judgment.

9

PROPOSAL NO. 1: ELECTION OF DIRECTORS

The Company’s Board of Directors is presently comprised of six members, who are divided into three classes, designated as Class I, Class II and Class III. One class of directors is elected by the stockholders at each annual meeting to serve from the time of their election until the third annual meeting of stockholders following their election. Class I directors consist of John Sheridan and Niamh Pellegrini; Class II directors consist of Dr. Andrew ElBardissi and Dr. Shaden Marzouk; and Class III directors consist of Jason Garland and Dr. David Bonita.

The Nominating and Corporate Governance Committee of the Board has recommended, and the Board has approved, the nomination of our Class I directors, John Sheridan and Niamh Pellegrini, for three-year terms expiring at the 2027 annual meeting of stockholders and until their respective successors are duly elected and qualified, or, if sooner, until the director’s death, resignation or removal. Each of Mr. Sheridan and Ms. Pellegrini is currently a director of the Company. Directors are elected by a plurality of the votes of the holders of shares present or represented by proxy and entitled to vote on the election of directors. The two nominees receiving the highest number of affirmative votes will be elected. Notwithstanding the forgoing, if any of the incumbent director candidates fails to receive a majority of the votes cast in an election, the director shall immediately tender his or her resignation to the Board. The Nominating and Corporate Governance Committee of the Board will make a recommendation to the Board as to whether to accept or reject the resignation of such incumbent director, or whether other action should be taken.

Proxies cannot be voted for a greater number of persons than the number of nominees named in this Proxy Statement. If any nominee should become unavailable to serve for any reason, it is intended that votes will be cast for a substitute nominee recommended by the Nominating and Corporate Governance Committee and approved by the Board. We have no reason to believe that any nominee named will be unable to serve if elected.

Nominees for Director and Continuing Directors

The names and ages of the nominees and continuing directors, length of service with the Company and Board committee memberships are set forth in the table below.

10

Board Diversity

In connection with nominating directors for election at the Annual Meeting and periodically throughout the year, the Nominating and Corporate Governance Committee considers the composition of the Board, including the right diversity, mix of characteristics and skills for the optimal functioning of the Board in its oversight of our Company. Members of our Board self-identify as set forth in the table below:

Board Biographies

A brief biography of each nominee and each continuing director is also set forth below, which includes information, as of the date of this Proxy Statement, regarding specific and particular experience, qualifications, attributes or skills of each nominee that led the Nominating and Corporate Governance Committee and the Board to believe that the director should serve on the Board.

Director Nominees

John Sheridan. Mr. Sheridan has served as a member of our Board of Directors since March 2021. Mr. Sheridan has been a member of the executive management team of Tandem Diabetes Care, Inc.

Mr. Sheridan holds a B.S. in Chemistry from the University of West Florida and an M.B.A. from Boston University.

INFORMATION REGARDING THE BOARD OF DIRECTORS

AND CORPORATE GOVERNANCE

This section describes key corporate governance guidelines and practices that we have adopted. Complete copies of our Corporate Governance Guidelines, the charters of the committees of the Board and our Code of Business Conduct and Ethics, described below, can be found in the Corporate Governance section of the Investors section of our website at https://ir.acutusmedical.com. Alternatively, you can request a copy of any of these documents free of charge by writing to: Takeo Mukai, Chief Executive Officer, c/o Acutus Medical, Inc., 2210 Faraday Ave., Suite 100 Carlsbad, CA 92008. Information on or accessible through our website is not incorporated by reference in this Proxy Statement.

Board Composition

Our Board of Directors currently consists of six members. In accordance with our amended and restated certificate of incorporation and our Bylaws, our directors are divided into three classes serving staggered three-year terms. At each annual meeting of stockholders, our directors will be elected to succeed the class of directors whose terms have expired. Our current directors are divided among the three classes as follows:

Only one class of directors will be elected at each annual meeting of our stockholders, with the other classes continuing for the remainder of their respective terms. Each director’s term continues until the election and qualification of their successor, or their earlier death, resignation or removal.

Director Resignation Policy

In November 2021, we adopted a “Majority Voting” policy as part of our Director Resignation Policy. Under this policy, if an incumbent director nominee fails to receive a majority of the votes cast in an election, the director shall immediately tender his or her resignation to the Board. The Nominating and Corporate Governance Committee of the Board, or such other committee designated by the Board, shall make a recommendation to the Board as to whether to accept or reject the resignation of such incumbent director, or whether other action should be taken. The Board shall act on the resignation, taking into account the committee’s recommendation, and publicly disclose (by a press release and filing an appropriate disclosure with the SEC) its decision regarding the resignation within 90 days following certification of the election results. If the Board accepts a director’s resignation pursuant to this paragraph, or if a nominee for director is not elected and the nominee is not an incumbent director, the remaining members of the Board may fill the resulting vacancy pursuant to the Bylaws of the Company.

Independence of the Board of Directors

The Board has affirmatively determined that all of the nominees and continuing directors are independent directors within the meaning of the applicable Nasdaq listing standards and relevant securities and other laws, rules and regulations regarding the definition of “independent” (the “Independent Directors”). In making these determinations, our Board of Directors considered the current and prior relationships that each non-employee director has with our Company and all other facts and circumstances our Board of Directors deemed relevant in determining their independence, including the beneficial ownership of our capital stock by each non-employee director, and the transactions involving them described in the section titled “Certain Relationships and Related Party Transactions”. There are no family relationships between any director and any of our executive officers.

14

Board Leadership Structure

The Board believes that it is important to retain the flexibility to allocate the responsibilities of the offices of Chairperson of the Board (“Chair”) and Chief Executive Officer in any manner that it determines to be in the best interests of the Company at any point in time.

Chair & CEO

The Board reviews its leadership structure periodically as part of its annual self-assessment process. In addition, the Board continues to monitor developments in corporate governance as well as the approaches our peers undertake. Our Board of Directors is currently chaired by Dr. Shaden Marzouk. As a general policy, our Board of Directors believes that separation of the positions of Chair and Chief Executive Officer reinforces the independence of our Board of Directors from management, creates an environment that encourages objective oversight of management’s performance and enhances the effectiveness of our Board of Directors as a whole. As such, Mr. Mukai serves as our Chief Executive Officer and Chief Financial Officer while Dr. Marzouk serves as the Chair but is not an officer. We currently expect and intend the positions of Chair and Chief Executive Officer to continue to be held by two individuals in the future.

Lead Independent Director

If necessary, the Board selects one independent director to serve as the Lead Independent Director to further balance the power amongst the Board. Prior to the appointment of Dr. Marzouk as independent Chair, Mr. Sheridan had been appointed as our lead independent director.

Our Corporate Governance Guidelines note that all directors are elected by the stockholders, and all have an equal voice. The Chair and the Chief Executive Officer are free, as is the Board as a whole, to call upon any one or more directors to provide leadership in a given situation should a special need arise.

The Board, including each of its committees, also has complete and open access to any member of the Company’s management and the authority to retain independent advisors as the Board or such committee deems appropriate. In addition, all members of the Audit Committee, the Nominating and Corporate Governance Committee and the Compensation Committee are Independent Directors, and the committee chairs have authority to hold executive sessions without management and non-Independent Directors present.

Role of the Board in Risk Oversight

One of the Board’s key functions is informed oversight of the Company’s risk management process. The Board believes that its current leadership structure facilitates its risk oversight responsibilities. In particular, the Board believes the independent Board and independent Board committees provide a well-functioning and effective balance to an experienced Chief Executive Officer. The Board does not have a standing risk management committee, but rather administers this oversight function directly through the Board as a whole, as well as through the various Board standing committees that address risks inherent in their respective areas of oversight. For example, the Board acts as the ultimate decision-making body of the Company and advises and oversees management, who are responsible for the day-to-day operations and management of the Company. The Audit Committee monitors compliance with legal and regulatory requirements and monitors cybersecurity and privacy risks. The Nominating and Corporate Governance Committee monitors the effectiveness of our Corporate Governance Guidelines and policies. The Compensation Committee assesses and monitors whether any of our compensation policies and programs has the potential to encourage excessive risk-taking.

It is the responsibility of the committee chairs to report findings regarding material risk exposures to the Board as quickly as possible. The Company’s Chief Executive Officer and Chief Financial Officer and General Counsel coordinate between the Board and management with regard to the determination and implementation of responses to any problematic risk management issues.

15

Meetings of the Board of Directors

The Board oversees our business. It establishes overall policies and standards and reviews the performance of management. During the fiscal year ended December 31, 2023, the Board held twelve meetings. Each Board member attended 75% or more of the aggregate meetings of the Board and of the committees on which they served that were held during the period for which they were a director or committee member. The Company’s directors are encouraged to attend our annual meetings of stockholders, but we do not currently have a policy relating to director attendance. Seven of the eight directors serving at the time of the 2023 annual meeting of stockholders attended that meeting.

Our Independent Directors meet from time to time in executive session. The Board and each of our standing independent committees typically hold an executive session of non-management directors (all of whom are Independent Directors) as a part of every regularly scheduled quarterly meeting.

Information Regarding Committees of the Board of Directors

The Board has a number of committees that perform certain functions for the Board. The current committees of the Board are the Audit Committee, the Compensation Committee and the Nominating and Corporate Governance Committee. Below is a description of each committee of the Board. Each of the committees has authority to engage legal counsel or other experts or consultants, as it deems appropriate to carry out its responsibilities. The Board has determined that each member of each committee meets the applicable Nasdaq listing standards and relevant securities and other laws, rules and regulations regarding “independence” and that each member is free of any relationship that would impair his or her individual exercise of independent judgment with regard to our Company.

Audit Committee

The Board has a separately designated standing Audit Committee established in accordance with Section 3(a)(58) of the Exchange Act. The Audit Committee was established by the Board to assist the Board in its oversight of the integrity of our financial statements and internal controls, and our compliance with legal and regulatory requirements. In addition, the Audit Committee assists the Board in its oversight of the qualification, independence and performance of our independent registered public accounting firm and recommends to the Board the appointment of our independent registered public accounting firm.

The members of our Audit Committee are Jason Garland, Niamh Pellegrini and Shaden Marzouk. Mr. Garland is the chair of our Audit Committee. The composition of our Audit Committee meets the requirements for independence under the current Nasdaq listing standards and SEC rules and regulations, including independence requirements specific to members of the audit committee of the board of directors of a listed company. Each member of our Audit Committee is financially literate. In addition, our Board of Directors has determined that all three members of our Audit Committee, Jason Garland, Shaden Marzouk and Niamh Pellegrini, are “audit committee financial experts” as defined in Item 407(d)(5)(ii) of Regulation S-K promulgated under the Securities Act of 1933, as amended (the “Securities Act”). In making that determination, the Board relied on the past business experience of Mr. Garland, Dr. Marzouk and Ms. Pellegrini. Please see the description of their business experience under the heading “Nominees for Director and Continuing Directors.” This designation does not impose any duties, obligations or liabilities that are greater than are generally imposed on members of our Audit Committee and our Board of Directors. Our Audit Committee is directly responsible for, among other things:

16

Our Audit Committee operates under a written charter that satisfies the applicable rules of the SEC and the listing standards of Nasdaq. In 2023, the Audit Committee met four times. The Audit Committee charter, most recently updated in June 2023, can be found in the Corporate Governance section of the Investors section of our website at https://ir.acutusmedical.com. Information on or accessible through our website is not incorporated by reference in this Proxy Statement. The Audit Committee charter grants the Audit Committee authority to obtain, at our expense, advice and assistance from internal and external legal, accounting or other advisors and consultants and other external resources that the Audit Committee considers necessary or appropriate in the performance of its duties.

As required by its charter, the Audit Committee reviews and assesses the adequacy of its charter at least annually and recommends any proposed changes to the Board for its consideration.

The Board annually reviews the Nasdaq listing standards’ definition of independence for Audit Committee members and has determined that all members of our Audit Committee are “independent” and “financially literate” under Nasdaq listing standards and that members of the Audit Committee received no compensation from the Company other than for service as a director.

Report of the Audit Committee of the Board of Directors

The Audit Committee reviews the Company’s financial reporting process on behalf of the Board. Management has the primary responsibility for the preparation and integrity of the consolidated financial statements and the reporting process, including establishing and monitoring the system of internal financial controls. In this context, during fiscal year 2023, the Audit Committee met and held discussions with management and KPMG, the Company’s independent registered public accounting firm. Management has represented to the Audit Committee that the Company’s consolidated financial statements for the fiscal year ended December 31, 2023, were prepared in accordance with U.S. generally accepted accounting principles, and the Audit Committee has reviewed and discussed the audited financial statements of the Company with management of the Company and with KPMG. In addition, the Audit Committee has discussed with KPMG the matters required to be discussed by the applicable requirements of the PCAOB AS 1301, Communications with Audit Committees, and the SEC. The Audit Committee has received from KPMG the written disclosures regarding the auditor’s independence required by applicable requirements of PCAOB Ethics and Independence Rule 3526, Communication with Audit Committees Concerning Independence, and has discussed with KPMG the independence of KPMG from the Company and its management. The Audit Committee has also concluded that the provision of the non-audit services to the Company in fiscal year 2023 was compatible with KPMG’s independence. Based on the foregoing, the Audit Committee has recommended to the Board, and the Board has approved, that the audited consolidated financial statements be included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023, for filing with the SEC. The Audit Committee and the Board have also recommended the selection of KPMG as the Company’s independent registered public accounting firm for the year ending December 31, 2024.

The material in this report is not deemed “soliciting material,” is not deemed “filed” with the SEC, is not subject to Regulation 14A or 14C or to the liabilities of Section 18 of the Exchange Act, and is not to be

17

incorporated by reference into any filing of Acutus under the Securities Act, whether made before or after the date hereof and irrespective of any general incorporation language in any such filing.

Jason Garland, Chair

Shaden Marzouk

Niamh Pellegrini

Compensation Committee

The members of our Compensation Committee are John Sheridan, Niamh Pellegrini and Andrew ElBardissi. Mr. Sheridan is the chair of our Compensation Committee. Each member of this committee is a non-employee director, as defined by Rule 16b-3 promulgated under the Exchange Act, and meets the requirements for independence under the current Nasdaq listing standards and SEC rules and regulations, including independence requirements specific to members of the compensation committee of the board of directors of a listed company. Our Compensation Committee is responsible for, among other things:

Our Compensation Committee operates under a written charter that satisfies the applicable rules of the SEC and the listing standards of the Nasdaq. During 2023, the Compensation Committee met three times. The Compensation Committee charter can be found in the Corporate Governance section of the Investors section of our website at https://ir.acutusmedical.com. Information on or accessible through our website is not incorporated by reference in this Proxy Statement. The Compensation Committee charter grants the Compensation Committee sole authority to retain or obtain the advice of a compensation consultant, legal counsel or other adviser, including the authority to approve the consultant’s reasonable compensation. The Compensation Committee may select such advisers, or receive advice from any other adviser, only after taking into consideration all factors relevant to that person’s independence from management, including those independence factors enumerated by Nasdaq rules.

Under the Compensation Committee charter, the Compensation Committee may, in its discretion, delegate its duties to a subcommittee.

As required by its charter, the Compensation Committee annually reviews and assesses the adequacy of its charter and recommends any proposed changes to the Board for its consideration.

Compensation Committee Processes and Procedures

The implementation of our compensation philosophy is carried out under the supervision of the Compensation Committee. The Compensation Committee charter requires that the Compensation Committee meet as often as it determines is appropriate to carry out its responsibilities under the charter. The agenda for each meeting is usually developed by the chair of the Compensation Committee, in consultation with other Compensation Committee members, management and the Compensation Committee’s independent advisors. The Compensation Committee also meets regularly in executive session. However, our Chief Executive Officer and

18

Chief Financial Officer and our General Counsel, in addition to the Compensation Committee’s independent advisors, may attend portions of the Compensation Committee meetings for the purpose of providing analysis and information to assist management with their recommendations on various compensation matters. Management does not participate in the executive sessions of the Compensation Committee.

In 2023, the Compensation Committee engaged Compensia, Inc. (“Compensia”) as an independent adviser to the Compensation Committee. That year, Compensia conducted analysis and provided advice on, among other things, appropriate equity compensation for our executive officers, including our Chief Executive Officer and Chief Financial Officer. Compensia reported directly to the Compensation Committee, which retained sole authority to direct the work of and engage Compensia. As part of its analysis, Compensia collected and analyzed compensation information from a peer group of comparable public companies. The Compensation Committee considered this report when making its determinations regarding executive compensation in 2023, as detailed below in the section titled “Executive Compensation.”

Nominating and Corporate Governance Committee

The Nominating and Corporate Governance Committee is generally responsible for identifying qualified Board candidates, recommending director nominees and appointments to Board committees, evaluating Board performance and overseeing the Company’s Corporate Governance Guidelines. The members of our Nominating and Corporate Governance Committee are David Bonita, Andrew ElBardissi and Shaden Marzouk. Dr. Bonita is the chair of our Nominating and Corporate Governance Committee. David Bonita, Andrew ElBardissi and Shaden Marzouk all meet the requirements for independence under the current Nasdaq listing standards. Our Nominating and Corporate Governance Committee is responsible for, among other things:

During 2023, the Nominating and Corporate Governance Committee met two times. Our Nominating and Corporate Governance Committee operates under a written charter that satisfies the applicable rules of the SEC and the listing standards of Nasdaq. A detailed discussion of the Nominating and Corporate Governance Committee’s procedures for recommending candidates for election as a director appears below under the caption “Procedures of the Nominating and Corporate Governance Committee.”

The Nominating and Corporate Governance Committee charter, most recently updated in May 2023, can be found in the Corporate Governance section of the Investors section of our website at https//ir.acutusmedical.com. The Nominating and Corporate Governance Committee charter complies with the guidelines established by Nasdaq. Information on or accessible through our website is not incorporated by reference in this Proxy Statement. The charter of the Nominating and Corporate Governance Committee grants the Nominating and Corporate Governance Committee authority to retain and terminate any advisers, including search firms to identify director candidates, compensation consultants as to director compensation and legal counsel, including sole authority to approve all such advisers’ fees and other retention terms.

Procedures of the Nominating and Corporate Governance Committee

In connection with nominating directors for election at the Annual Meeting and periodically throughout the year, the Nominating and Corporate Governance Committee considers the composition of the Board and each

19

committee of the Board to evaluate its effectiveness and whether changes should be considered to either the Board or any of the committees. In support of this process, the Board has determined that the Board as a whole must have the right diversity, mix of characteristics and skills for the optimal functioning of the Board in its oversight of our Company. The Board considers the following factors and qualifications, without limitation:

Pursuant to the Nominating and Corporate Governance Committee charter, the Nominating and Corporate Governance Committee intends to periodically review the composition of the Board in light of current challenges and needs of the Board and the Company and determine whether it may be appropriate to add or remove individuals after considering issues of judgment, diversity, skills, background and experience. Although the Nominating and Corporate Governance Committee does not have a formal policy regarding diversity on the Board, the Nominating and Corporate Governance Committee is sensitive to the importance of nominating persons with different perspectives and experience to enhance the deliberation and decision-making processes of the Board.

Once the Nominating and Corporate Governance Committee and the Board determine that it is appropriate to add a new director, either as a replacement or as a new position, the Nominating and Corporate Governance Committee uses a flexible set of procedures in selecting individual director candidates. This flexibility allows the Nominating and Corporate Governance Committee to adjust the process to best satisfy the objectives it is attempting to accomplish in any director search. The first step in the general process is to identify the type of candidate the Nominating and Corporate Governance Committee may desire for a particular opening, including establishing the specific target skill areas, experiences and backgrounds that are to be the focus of a director search. The Nominating and Corporate Governance Committee may consider candidates recommended by management, by members of the Nominating and Corporate Governance Committee, by the Board, by stockholders or by a third party it may engage to conduct a search for possible candidates. In considering candidates submitted by stockholders, the Nominating and Corporate Governance Committee will take into consideration the needs of the Board and the qualifications of the candidate.

In order for a stockholder to have a candidate considered by the Nominating and Corporate Governance Committee, a stockholder should submit a written recommendation that includes (A) as to each person whom the stockholder proposes to nominate for election or reelection as director, (1) all information relating to such person that is required to be disclosed in solicitations of proxies for election of directors, or is otherwise required, in each case pursuant to Regulation 14A under the Exchange Act, including such person’s written consent to being named in the proxy statement and form of proxy as a nominee and to serving as a director if elected, and (2) a reasonably detailed description of any compensatory, payment or other financial agreement, arrangement or understanding that such person has with any other person or entity other than the Company including the amount of any payment or payments received or receivable thereunder, in each case in connection with candidacy or service as a director of the Company, and (B) as to the stockholder giving the notice and the beneficial owner, if any, on whose behalf the proposal is made, (1) the name and address of such stockholder (as they appear on the Company’s books) and any such beneficial owner; (2) for each class or series, if any, the number of shares of capital stock of the Company that are held of record or are beneficially owned by such stockholder and by any

20

such beneficial owner; (3) a description of any agreement, arrangement or understanding between or among such stockholder and any such beneficial owner, any of their respective affiliates or associates, and any other person or persons (including their names) in connection with the proposal of such nomination or other business; (4) a description of any agreement, arrangement or understanding (including, regardless of the form of settlement, any derivative, long or short positions, profit interests, forwards, futures, swaps, options, warrants, convertible securities, stock appreciation or similar rights, hedging transactions and borrowed or loaned shares) that has been entered into by or on behalf of, or any other agreement, arrangement or understanding that has been made, the effect or intent of which is to create or mitigate loss to, manage risk or benefit of share price changes for, or increase or decrease the voting power of, such stockholder or any such beneficial owner or any such nominee with respect to the Company’s securities; (5) a representation that the stockholder is a holder of record of stock of the Company entitled to vote at such meeting and intends to appear in person or by proxy at the meeting to bring such nomination or other business before the meeting; (6) a representation as to whether such stockholder or any such beneficial owner intends or is part of a group that intends to (i) deliver a proxy statement and/or form of proxy to holders of at least the percentage of the voting power of the Company’s outstanding capital stock required to approve or adopt the proposal or to elect each such nominee and/or (ii) otherwise to solicit proxies from stockholders in support of such proposal or nomination; and/or (iii) solicit holders of shares representing at least 67% of the outstanding securities of the Company generally entitled to vote on the election of directors in support of director nominees other than the Company’s nominees in accordance with Rule 14a-19 promulgated under the Exchange Act, (7) any other information relating to such stockholder, beneficial owner, if any, or director nominee or proposed business that would be required to be disclosed in a proxy statement or other filing required to be made in connection with the solicitation of proxies in support of such nominee or proposal pursuant to Section 14 of the Exchange Act; and (8) such other information relating to any proposed item of business as the Company may reasonably require to determine whether such proposed item of business is a proper matter for stockholder action. Stockholder recommendations should be addressed to the Nominating and Corporate Governance Committee in care of our Chief Executive Officer at 2210 Faraday Ave., Suite 100, Carlsbad, CA 92008.

Once candidates are identified, the Nominating and Corporate Governance Committee conducts an evaluation of qualified candidates. The evaluation generally includes interviews and background and reference checks. There is no difference in the evaluation process of a candidate recommended by a stockholder as compared to the evaluation process of a candidate identified by any of the other means described above. In identifying and evaluating potential nominees to serve as directors, the Nominating and Corporate Governance Committee will examine each nominee on a case-by-case basis regardless of who recommended the nominee and take into account all factors it considers appropriate.

If the Nominating and Corporate Governance Committee determines that a candidate should be nominated as a candidate for election to the Board, the candidate’s nomination is then recommended to the Board, and the directors may in turn conduct their own review to the extent they deem appropriate. When the Board has agreed upon a candidate, such candidate is recommended to the stockholders for election at an annual meeting of stockholders or appointed as a director by a vote of the Board as appropriate.

Each of the current Class I directors have been recommended by the Nominating and Corporate Governance Committee to the Board for reelection as our directors at the Annual Meeting, and the Board has approved such recommendations.

Stockholder Communications with the Board of Directors

Our relationship with our stockholders is an important part of our corporate governance program. Engaging with our stockholders helps us to understand how they view us, to set goals and expectations for our performance, and to identify emerging issues that may affect our strategies, corporate governance, compensation practices or other aspects of our operations. We communicate with stockholders and other stakeholders through various media, including our annual report and SEC filings, proxy statement, news releases and our website.

21

The Board has adopted a process for stockholders and others to send communications to the Board or any director. All such communications should be sent by mail addressed to the Board or any particular director at 2210 Faraday Ave., Suite 100, Carlsbad, CA 92008, c/o Takeo Mukai, Chief Executive Officer. All communications received by Mr. Mukai will be sent directly to the Board or any particular director.

Code of Business Conduct and Ethics

Our Board of Directors has adopted a Code of Business Conduct and Ethics that applies to all of our employees, officers and directors, including our principal executive officer, principal financial officer, principal accounting officer and other executive and senior financial officers. The full text of our Code of Business Conduct and Ethics is available in the Corporate Governance section of the Investors section of our website at https://ir.acutusmedical.com. Information on or accessible through our website is not incorporated by reference in this Proxy Statement. We intend to disclose future amendments to our Code of Business Conduct and Ethics, or any waivers of such code, on our website or in public filings.

Compensation Recoupment Policy

On May 17, 2023, the Board adopted a Compensation Recoupment Policy. The Compensation Recoupment Policy, adopted in compliance with Exchange Act Rule 10D and the corresponding Nasdaq listing standards, applies to current and former executive officers of the Company. In the event the Company is required to restate its financial statements as a result of events described in the Nasdaq listing standards effective October 2, 2023, the Compensation Committee is authorized to recover incentive compensation awarded to a covered executive in accordance with its Compensation Recoupment Policy.

Anti-Hedging and Anti-Pledging

The Board has adopted a formal anti-hedging and anti-pledging policy for our employees, officers and directors. Under our Insider Trading Policy, which was adopted by the Board in August 2020 and most recently updated in May 2023, our employees, officers and directors are prohibited from engaging in transactions in publicly-traded options, such as puts and calls, and other derivative securities with respect to the Company’s securities. This prohibition extends to any hedging or similar transaction designed to decrease the risks associated with holding Company securities. In addition, employees, officers and directors may not pledge Company securities under any circumstances, including by purchasing Company securities on margin or holding Company securities in a margin account, or pledging securities as collateral for loans.

PROPOSAL NO. 2: RATIFICATION OF THE SELECTION OF THE INDEPENDENT REGISTERED

PUBLIC ACCOUNTING FIRM FOR ACUTUS

On April 12, 2024, the Board selected and approved of KPMG as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2024. KPMG has served as our independent registered public accounting firm since 2015. Representatives of KPMG plan to attend the Annual Meeting and will be available to answer appropriate questions from stockholders. They will have the opportunity to make a statement if they desire to do so.

Neither our Bylaws nor other governing documents or applicable law require stockholder ratification of the selection of KPMG as the Company’s independent registered public accounting firm. However, the Board is submitting the selection of KPMG to the stockholders for ratification as a matter of good corporate practice. If the stockholders fail to ratify the selection, the Board will reconsider whether to retain KPMG. Even if the selection is ratified, the Board in its discretion may direct the appointment of a different independent registered public accounting firm at any time during the year if the Board determines that such a change would be in the best interest of the Company and its stockholders.

Independent Registered Public Accounting Firm

The following is a summary of the fees and services provided by KPMG to the Company for fiscal years 2023 and 2022:

The Audit Committee or delegate thereof pre-approves the scope of the audit, audit-related and tax services provided by our independent registered public accounting firm, as well as all associated fees and terms, pursuant to pre-approval policies and procedures established by the Audit Committee. The Audit Committee evaluates the independent registered public accounting firm’s qualifications, performance and independence, and presents its conclusions to the full Board on at least an annual basis.

All of the services provided by KPMG for fiscal years 2023 and 2022, and fees for such services, were pre-approved by the Audit Committee in accordance with these standards.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE IN FAVOR OF PROPOSAL NO. 2.

Legal Proceedings

The Company and certain of its current and former officers have been named as defendants in two putative securities class action lawsuits filed by putative stockholders in the United States District Court for the Southern District of California on February 15, 2022 and March 23, 2022 (case numbers 22CV206 and 22CV0388). The plaintiffs allege violations of Section 10(b) of the Exchange Act and Rule 10b-5, and Section 20(a) of the Exchange Act. The complaints allege that the defendants made false and misleading statements about the Company’s business, prospects and operations. The claims are based upon statements made in filings made by

26

the Company with the SEC, press releases and on earnings calls between May 13, 2021 and November 11, 2021. The lawsuits seek, among other relief, a determination that the alleged claims may be asserted on a class-wide basis, unspecified compensatory damages, attorney’s fees, other expenses and costs. On July 19, 2022, the court consolidated the two actions, appointed a lead plaintiff and appointed lead counsel for the proposed class. On September 16, 2022, the lead plaintiff filed a consolidated amended complaint. The defendants thereafter filed a motion to dismiss. On September 27, 2023, the court granted the defendant’s motion to dismiss in its entirety, but gave plaintiffs leave to file an amended complaint. On October 27, 2023, the plaintiffs filed a second amended complaint asserting similar claims. The defendants thereafter filed a motion to dismiss. On March 26, 2024, the court granted the defendant’s motion to dismiss in its entirety, but gave plaintiffs leave to file an amended complaint, also requiring plaintiff to specifically identify and detail how any new allegations will cure the sited deficiencies in plaintiff’s two prior complaints.

On February 16, 2024, Biotronik SE & Co. KG, Germany (“Biotronik”) and VascoMed GmbH, Germany (collectively, the “Biotronik Parties”) filed a Demand for Arbitration and Statement of Claim against the Company with the American Arbitration Association (who notified the Company of the filing on February 29, 2024), alleging that the Company breached its contractual obligations under five agreements relating to the licensing, manufacturing, distribution and development of certain medical devices as a result of the wind down of its mapping and ablation businesses. The Biotronik Parties allege that the Company breached, among other things, its obligations (i) to develop, manufacture, use and commercialize certain product lines under the License and Distribution Agreement entered into on July 2, 2019 with the Biotronik Parties and the Manufacture and Supply Agreement entered into on April 19, 2022 with Biotronik; (ii) to distribute Biotronik products and manufacture and supply Acutus products under the Bi-Lateral Distribution Agreements entered into with Biotronik on May 11, 2020, as applicable; and (iii) to use commercially reasonable efforts to perform and complete its responsibilities under the Feasibility and Development Agreement entered into on June 2, 2021 with Biotronik. The Statement of Claim seeks $38.0 million in damages as well as attorney’s fees, interest, other expenses and costs. The Company responded to the Statement of Claim on April 1, 2024 and disputes the Biotronik Parties’ allegations.

There are no other material proceedings to which any director, officer or affiliate of the Company, any owner of record or beneficially of more than 5% of any class of voting securities of the Company, any associate of any such director, officer, affiliate of the Company, or security holder is a party adverse to the Company or any of its subsidiaries or has a material interest adverse to the Company or any of its subsidiaries.

EXECUTIVE COMPENSATION

Our named executive officers (“NEOs”) for fiscal year 2023, who consist of our current and former principal executive officers serving at any time during fiscal year 2023, and the two individuals who served as executive officers during fiscal year 2023 and would have been the next two most highly compensated executive officers (other than the principal executive officers) had they remained executive officers through the end of the fiscal year, are:

As an emerging growth company, we have opted to comply with the executive compensation disclosure rules applicable to emerging growth companies pursuant to the JOBS Act, which require compensation disclosure for each individual serving as our principal executive officer during fiscal year 2023 and the two most highly compensated executive officers other than such principal executive officers.

During fiscal year 2023, David Roman served as the Company’s President and Chief Executive Officer, and Takeo Mukai and Kevin Mathews were our next two most highly compensated executive officers, serving as of the end of fiscal year 2023 as Chief Financial Officer and Senior Vice President, Commercial, respectively.

Summary Compensation Table

The following table discloses compensation earned by our NEOs for each of the last three fiscal years during which they served as NEOs.

28

Cash Compensation

Base Salary

The NEOs receive base salaries to compensate them for services rendered to the Company. The base salaries are intended to provide a fixed component of compensation that is commensurate with each executive’s experience, role and responsibilities. The amount that each NEO received in base salary for 2023 is set forth in the Summary Compensation Table above. Our Board of Directors, on recommendation by the Compensation Committee, set NEO base salaries for 2023 based on the Compensation Committee’s review of available market information. See the “Salary” column in the 2023 Summary Compensation Table for the base salary amounts earned by the named executive officers in 2023.

Short-Term Cash Incentive Program

Historically, we maintained an annual bonus program that rewarded each of our NEOs for our performance against business goals, and for the officer’s performance against his or her individual goals. Our Board of Directors established performance goals for this program each year and then evaluated performance to these established goals to determine the amount of each award. For 2022, our performance goals included revenue achievement, gross margin improvement, console utilization and certain research and development and clinical milestones. This program was based on performance over a calendar year and paid out on or before March 15 of the following year, subject to the NEO’s continued service through the payment date. All awards under this program were subject to management discretion. For 2023, in conjunction with the Company’s announcement of a realignment of resources and corporate restructuring, the Company ceased the short-term cash incentive bonus program.

Equity Awards

We consider long-term equity incentives to be a critical component of our executive compensation program as they motivate and reward executive officers over the long-term and align their interests with those of our stockholders. We have historically granted stock options and restricted stock units (“RSUs”) to our executive

29

officers. Options are granted with an exercise price per share that is no less than the fair market value of the Company’s common stock on the date of grant of such award. Options and RSUs generally vest over a 4 year-period from the date of grant with 25% of each award subject to one-year cliff-vesting. However, in 2022 and 2023, the Company granted options and RSUs that vest over a 2 year-period from the date of grant with 50% of each award subject to one-year cliff vesting and the remainder vesting over the subsequent year. See the “Outstanding Equity Awards at Fiscal Year End” table below for a description of the vesting schedule of option and RSU awards held by our NEOs as of December 31, 2023. Option and RSU awards may be subject to acceleration of vesting under certain termination and change of control events, as further described below under the section titled “Potential Payments upon Termination or Change of Control.” The terms of the 2020 Equity Incentive Plan (the “2020 Plan”) and the 2011 Equity Incentive Plan (the “2011 Plan”) are described under the section titled “Employee Benefit and Stock Plans” below.

On July 15, 2022, and in accordance with the terms of the Company’s 2011 Plan and 2020 Plan, the Company’s Board of Directors approved a stock option repricing of “underwater” options wherein the exercise price of each outstanding option of each employee employed as of July 25, 2022 (including each outstanding option held by our fiscal year 2022 NEOs, other than Mr. Burgess who was not employed on such date) was reduced to the price of the Company’s common stock as of the market close on July 25, 2022. As of that date, the closing price of the Company’s common stock was $1.34 per share. All repriced options otherwise remained outstanding following the repricing in accordance with their original terms and conditions.

Executive Officer Offer Letters and Employment Arrangements

We have entered into employment agreements with each of our NEOs, the key terms of which are described below. In addition, as a condition of employment, each of our NEOs has also entered into our standard, at-will employment, confidential information, invention assignment and arbitration agreements. Under these agreements, each officer is subject to a covenant not to solicit our employees, both during the officer’s employment and for the 12-month period following termination of employment for any reason.

Takeo Mukai

We are party to an employment agreement dated as of January 9, 2023 with Mr. Mukai, our Chief Executive Officer and Chief Financial Officer. This agreement does not have a specific term and provides that Mr. Mukai is an at-will employee. Mr. Mukai’s current base salary is $375,000, and his annual target under our annual cash incentive program was 60% of his annual base salary. Mr. Mukai is eligible for severance benefits under his employment agreement, subject to his execution of a general release in our favor, as more fully described in “Potential Payments upon Termination or Change of Control.”

David Roman

We were party to an employment agreement dated as of March 1, 2021, as amended on July 20, 2022 with David Roman, our former President and Chief Executive Officer. This agreement did not have a specific term and provided that Mr. Roman was an at-will employee. Mr. Roman’s base salary was $500,000 and his annual target under our annual cash incentive program was 60% of his annual base salary. On November 8, 2023, the Company announced a realignment of resources and corporate restructuring, including a reduction in the workforce. As part of the reduction in workforce, Mr. Roman separated from the Company, effective January 7, 2024. Upon his separation, Mr. Roman received a cash retention bonus equal to $300,000, which was granted to him on November 6, 2023 and payable to him as a lump sum on January 7, 2024, subject to his continued service through such payment date.

On January 7, 2024, Mr. Roman entered into a separation agreement with the Company. Pursuant to the separation agreement (as contemplated by his employment agreement), in consideration of a customary release of claims, Mr. Roman received cash severance equal to one year of Mr. Roman’s annual base salary ($500,000) payable as a lump sum as well as the accelerated vesting of 67,500 shares underlying RSUs.

30

Pursuant to a consulting agreement entered into with the Company on January 8, 2024, Mr. Roman provided reasonable assistance to the Company with respect to the transition of the Company’s chief executive officer role and provided advisory services related to the Company’s corporate restructuring. Pursuant to his consulting agreement, Mr. Roman was entitled, during the term of the consulting agreement, to compensation equal to $200 per hour of service. The consulting agreement was terminated by mutual agreement on January 26, 2024 upon Mr. Roman’s commencement of subsequent employment.

Kevin Mathews

We were party to an employment agreement dated as of May 1, 2022 with Mr. Piscitello, our former Senior Vice President, Commercial. This agreement did not have a specific term and provided that Mr. Mathews was an at—will employee. Mr. Mathew’s base salary was $310,000 and his annual target under our annual cash incentive program was 50% of his annual base salary. On November 8, 2023, the Company announced a realignment of resources and corporate restructuring, including a reduction in the workforce. As part of the reduction in workforce, Mr. Mathews separated from the Company, effective January 7, 2024. Upon his separation, Mr. Mathews received a cash retention bonus equal to $38,000, which was granted to him on November 6, 2023 and payable to him as a lump sum on February 6, 2024, subject to his continued service through such payment date.

Potential Payments upon Termination or Change of Control

We provide the following severance benefits to our NEOs in the event of a qualifying termination of employment under the terms of their employment agreements. Under the terms of each NEO’s employment agreement in effect as of December 31, 2023, each NEO is entitled to severance benefits in the event of (i) an involuntary termination of the NEO’s employment without “Cause” or (ii) a voluntary termination of the NEO’s employment due to an event of “Good Reason” (as each such term is defined in the employment agreement), in each case subject to the NEO’s execution and non-revocation of a general release of claims. If an NEO’s termination occurs within 90 days prior, or within twelve (12) months following, the effective date of a “change in control,” as defined in the employment agreement (which we refer to as the “Change in Control Period” below), the severance benefits are increased, as described below.

Takeo Mukai

In the event of Mr. Mukai’s termination of employment by the Company without Cause or by Mr. Mukai for Good Reason, outside of the Change in Control Period, Mr. Mukai is entitled to the following severance payments: (i) a lump sum payment equal to nine months of his base salary and (ii) nine months of reimbursement for COBRA continuation premiums.

In the event of Mr. Mukai’s termination of employment by the Company without Cause or by Mr. Mukai for Good Reason within the Change in Control Period, Mr. Mukai is entitled to the following severance payments: a lump sum payment equal to the sum of (i) his base salary plus (ii) his target bonus amount; 12 months of reimbursement for COBRA continuation premiums; and accelerated vesting of any outstanding equity awards (with any performance conditions being deemed satisfied at 100%).

The severance benefits described above are all subject to Mr. Mukai’s general release of the Company and its affiliates, which may include an agreement not to disparage the Company or solicit its employees. “Change in Control” has the same meaning assigned to such term in the 2011 Plan.

David Roman

We were party to an employment agreement dated as of March 1, 2021, as amended on July 20, 2022 with Mr. Roman, our former President and Chief Executive Officer. Upon Mr. Roman’s separation from the Company on January 7, 2024 and receipt of his general release of the Company and its affiliates, he received the following severance payments for which he was entitled under his employment agreement upon an involuntary termination

31

without Cause: $500,000 representing 100% of his base salary, paid in a lump sum following his termination, plus 12 months of reimbursement for COBRA continuation premiums, as well as the accelerated vesting of 67,500 shares underlying RSUs.

Kevin Mathews

We were party to an employment agreement dated as of May 1, 2022 with Mr. Mathews, our Senior Vice President, Commercial.

The following table sets forth information concerning unexercised options, stock that has not vested and equity incentive plan awards for our NEOs as of the end of our fiscal year ended December 31, 2023.

Outstanding Equity Awards at 2023 Fiscal Year End

32

Employee Benefit and Stock Plans

Our NEOs are entitled to participate in our compensation and benefits plans as described below.

2020 Plan

In August 2020, our Board of Directors adopted and our stockholders approved our 2020 Plan, which became effective in connection with our initial public offering in August 2020. Our 2020 Plan replaced our 2011 Plan. Following the effectiveness of the 2020 Plan, no further equity awards may be granted under our 2011 Plan. The 2020 Plan provides for the grant of incentive stock options (“ISOs”), nonstatutory stock options, stock appreciation rights, restricted stock, RSUs, performance units, performance shares and other equity-based awards. ISOs may be granted only to employees. All other awards may be granted to employees, directors and consultants.

Our Board of Directors, or one or more duly authorized committees thereof, have the authority to administer the 2020 Plan. Unless the terms of an optionholder’s stock option agreement provide otherwise, if an optionholder’s service relationship with us ceases for any reason other than disability or death, the optionholder may generally exercise any vested options for a period of three months following the cessation of service. In the event of certain corporate transactions specified in our 2020 Plan, including a merger or change of control, as defined in our 2020 Plan, the administrator may, in its discretion, take certain actions with respect to outstanding awards, including the continuation or assumption of awards.

Employee Stock Purchase Plan

In August 2020, our Board of Directors adopted, and our stockholders approved, our Employee Stock Purchase Plan (the “ESPP”), which became effective in connection with our initial public offering in August 2020. Historically, our Board of Directors, or one or more duly authorized committees thereof, had the authority to administer the ESPP. Each eligible employee who was a participant in the ESPP could purchase shares of our common stock by authorizing payroll deductions at a minimum of 1% and up to 10% of his or her eligible compensation for each pay period.

Offering periods under the ESPP were six months in duration, commencing on May 15 and November 15 and ending on the following May 14 or November 14. The purchase price per share of our common stock under

33

the ESPP was equal to 85% of the fair market value of the common stock on either the first or the last day of the offering period, whichever was lower, or such higher price for any given offering period as may be determined by the administrator, provided that no more than 1,250 shares of our common stock or such other lesser maximum number established by the plan administrator may be purchased by any one employee during each offering period. Under applicable tax rules, an employee may purchase no more than $25,000 worth of common stock, valued at the start of the purchase period, under the ESPP in any calendar year.

An employee’s rights under the ESPP terminated upon voluntary withdrawal from the plan or when the employee ceased employment for any reason. Prior to the effective time of any corporate transaction, as defined in the ESPP, the ESPP would terminate and shares would be purchased prior to the effective time as determined by the plan administrator, unless the ESPP was continued by the Company or assumed by the surviving corporation.

In November 2023, our Board of Directors terminated the ESPP, effective November 8, 2023, and resolved to return to the respective contributors all contributions made during the purchase period ending November 14, 2023. No new purchase periods under the ESPP commenced as of the date of termination.

2011 Plan

Our Board of Directors approved our 2011 Plan in March 2011, and it was amended in September 2019. The 2011 Plan provided for grants of ISOs, nonstatutory stock options, stock appreciation rights, restricted stock awards and RSUs to employees, directors or consultants. In connection with our initial public offering, our 2011 Plan was terminated, and no further equity awards may be granted under our 2011 Plan. Any awards forfeited under our 2011 Plan will be added back to our share reserve under our 2020 Plan.

Each stock option granted under our 2011 Plan will become exercisable upon vesting and will remain exercisable until its termination date on the tenth anniversary of the award, or, if earlier, until the day that is three months after the recipient ceases to be a service provider due to death or disability, or the day that is three months after the recipient ceases to be a service provider for any other reason.

In the event of certain corporate transactions specified in the 2011 Plan, including a merger or change of control, as defined in the 2011 Plan, the administrator may, in its discretion, take certain actions with respect to outstanding awards, including the continuation or assumption of awards.

Defined Contribution Plan

We currently maintain a 401(k) retirement savings plan (the “401(k) plan”) for our employees, including our NEOs, who satisfy certain eligibility requirements. The 401(k) plan is intended to qualify as a tax-qualified plan under Section 401(k) of the Internal Revenue Code (the “Code”). Our NEOs are eligible to participate in the 401(k) plan on the same basis as our other employees. The Code allows eligible employees to defer a portion of their compensation, within prescribed limits, on a pre-tax basis through contributions to the 401(k) plan. We reserve the right to make discretionary matching contributions or non-elective contributions under the 401(k) plan. Similar to prior years, in fiscal year 2023, we did not provide a matching contribution or a non-elective contribution under the 401(k) plan.

We do not maintain any defined benefit pension plans.

Director Compensation

Our directors play a critical role in guiding our strategic direction and overseeing the management of Acutus. The many responsibilities and risks and the substantial time commitment of being a director require that

34

we provide adequate compensation commensurate with our directors’ workload and opportunity costs. Independent Directors receive a combination of annual cash retainers and annual grants of options or RSUs., as described further below

Prior to his resignation in 2024, our one employee director, Mr. Roman, did not receive additional compensation for his services as a director. For more information on Mr. Roman’s compensation as an officer, see the section titled “Executive Compensation.” For more information on our non-employee director compensation, see the section titled “Director Compensation in 2023.”

Equity Compensation

Under the Company’s Outside Director Compensation Policy, as in effect prior to February 13, 2023, newly appointed non-employee directors received an initial stock option award with a grant date value of $140,000 as well as an RSU award with a grant date value of $60,000, and each incumbent non-employee director who served as such as of the date of our annual meeting, received a stock option award with a grant date value of $84,000 and an RSU award with a grant date value of $36,000, except that the annual grant for 2022 consisted of a stock option and an RSU award with respect to a fixed number of shares of Company stock in the amount of 13,595 and 9,000 respectively. In February 2023, the Board amended the policy to provide newly appointed non-employee directors an initial stock option award of 32,500 shares as well as an RSU award of 14,000 shares, and each incumbent non-employee director who served as such as of the date of our annual meeting, received a stock option award of 19,600 shares and an RSU award of 8,400 shares. In addition, an outside director serving in the capacity of Board Chair received an additional stock option award of 5,880 shares and an additional RSU award of 2,520 shares.

Each initial option grant and each initial RSU grant vests ratably over a three-year period following the commencement of the non-employee director’s services. In the case of the initial option grant, 1/3 of the shares vest on the first anniversary of the non-employee director’s commencement date, and the remaining two-thirds vest in equal monthly installments, and, in the case of the initial RSU grant, 1/3 of the shares vest on each anniversary of the non-employee director’s commencement date, in each case, subject to the non-employee director’s continuous service with us on each applicable vesting date. Each annual option and RSU grant vests on the first anniversary of the grant date, subject to the non-employee director’s continuous service with us through the vesting date. All then outstanding awards held by non-employee directors will vest upon a “Change in Control” (as defined in the 2020 Plan), subject to the non-employee director’s continuous service with us through the date of such Change in Control.

On February 13, 2023, our Compensation Committee approved an amendment to the Company’s Outside Director Compensation Policy, following which, upon being appointed to our Board of Directors, any new non-employee director will receive a stock option award with respect to 32,500 shares as well as an RSU award with respect to 14,000 shares, and each incumbent non-employee director who is serving as such as of the date of our annual meeting will receive a stock option award with respect to 19,600 shares and an RSU award with respect to 8,400 shares. Under the amended policy, a non-employee director serving in the capacity of Chair will receive an additional stock option award with respect to 5,880 shares and an RSU award with respect to 2,520 shares. All other terms of the Company’s Outside Director Compensation Policy remain as in effect prior to the amendment.

Cash Compensation

The following table is a summary of the annual cash compensation provided for under the Company’s Outside Director Compensation Policy other than for Mr. Roman, who was an executive officer and did not

35

receive any additional compensation for services provided as a director, and for Mr. Huennekens, who was paid cash compensation under his Chairperson Agreement described below:

Chairperson Agreement

We entered into a Chairperson Agreement with Mr. Huennekens under which we agreed to pay him at a rate of $500 per hour for his service as Chair. Pursuant to this agreement, we granted Mr. Huennekens an RSU award on June 30, 2019 with respect to 567,509 shares of our common stock. The vesting of this award was subject to Mr. Huennekens’ continued service through designated vesting dates over a period ending on March 1, 2022 and the occurrence of an initial public offering or change in control with respect to the Company within ten years of the date of grant.

Mr. Huennekens’ Chairperson Agreement provided that in the event that Mr. Huennekens’ service is terminated by us without “cause” or by Mr. Huennekens with “good reason” (each as defined in such agreement), then, subject to Mr. Huennekens’ waiver and release in a form reasonably satisfactory to the Company, his equity compensation awards, all of which had already vested as of March 1, 2022, would become vested and exercisable to the extent they would have become vested and exercisable if he had continued service to the Company for the 12-month period following the date of termination. The agreement also provided that in the event of a change in control (as defined in our 2011 Plan), Mr. Huennekens’ equity compensation awards would become fully vested and exercisable. Mr. Huennekens resigned from Board effective January 15, 2024.

Other than as described below, there have not been, nor are there any currently proposed, transactions or series of similar transactions meeting these criteria to which we have been or will be a party other than compensation arrangements, which are described where required under the sections titled “Director Compensation” and “Executive Compensation.”

2019 Credit Agreement

On May 20, 2019, we entered into a credit agreement (the “2019 Credit Agreement”) with the lenders party thereto from time to time, ORO II as origination agent and Wilmington Trust, National Association as administrative agent. The 2019 Credit Agreement provided us with a senior term loan facility in aggregate principal amount of $70.0 million and generally bore interest at a variable rate. We recorded $5.7 million and $2.8 million in interest expense related to this debt agreement for the year ended December 31, 2021 and the six months ended June 30, 2022, respectively. As of December 31, 2021, we had $40.0 million in aggregate principal amount of long-term debt outstanding under the 2019 Credit Agreement. On June 30, 2022, we fully repaid the $40.0 million in aggregate principal amount outstanding under the 2019 Credit Agreement (see “2022 Amended and Restated Credit Agreement” below).

The lenders under the 2019 Credit Agreement were ORO II and DPD III. Each of ORO II and DPD III, together with their respective affiliates, are holders of 5% or more of our capital stock (see “Material Relationships” below).

2022 Amended and Restated Credit Agreement

On June 30, 2022, we entered into a new debt facility with certain affiliates of Deerfield Management as lenders (the “Lenders”). The amended and restated credit agreement (the “2022 Credit Agreement”) is for an aggregate principal amount of $35.0 million (the “Term Loan”) and amends and restates our 2019 Credit Agreement. The proceeds from the Term Loan were, among other things, used to refinance the term loan under the 2019 Credit Agreement.

The Term Loan has a five-year term and bears interest at one-month adjusted Term SOFR, with a floor of 2.50% per annum, plus 9.00% per annum (subject to increase following the occurrence of an event of default).

On August 4, 2023, we entered into that certain Amendment No. 1, dated August 4, 2023 (“Amendment No.1”) to the 2022 Credit Agreement with Deerfield. Pursuant to Amendment No. 1, the 2022 Credit Agreement was amended to decrease the amount of cash we are required to maintain pursuant to the minimum liquidity covenant in the 2022 Credit Agreement to $5,000,000 for a period of 18 months, at which point the amount required under the minimum liquidity covenant shall increase to $20,000,000 (or, if certain conditions are met, $10,000,000), in exchange for a fee paid by us.

On November 8, 2023, we entered into that certain Amendment No. 2, dated November 8, 2023 (“Amendment No. 2”) to the 2022 Credit Agreement with Deerfield. Pursuant to Amendment No. 2, the 2022

39

Credit Agreement was amended to, among other things: (i) adjust and increase the amortization schedule such that payments commence on June 30, 2024 and are made 12, 24 and 36 months (i.e., the scheduled maturity date) following June 30, 2024; (ii) limit the business activities we may engage in; and (iii) require us to maintain a minimum liquidity of $10,000,000 at all times, in exchange for fees paid by us.

On March 4, 2024, we entered into Waiver and Amendment No. 3 (“Amendment No. 3”) to the 2022 Credit Agreement with Deerfield. Previously, on February 16, 2024, the Biotronik Parties filed a Demand for Arbitration and Statement of Claim (the “Demand”) against us with the American Arbitration Association (who notified us of the Demand on February 29, 2024), alleging that we breached our contractual obligations under five agreements relating to the licensing, manufacturing, distribution and development of medical devices as a result of the wind down of our businesses. Pursuant to Amendment No. 3, Deerfield has agreed to waive any Default or Event of Default (each defined in the 2022 Credit Agreement) that has arisen or may arise in connection with the Demand. In addition, pursuant to Amendment No. 3 among other things, (i) the 2022 Credit Agreement was amended such that (x) a Change in Control (as defined in the 2022 Credit Agreement) under the 2022 Credit Agreement would not be deemed to occur in the event our common stock ceases to be listed on Nasdaq (without a comparable re-listing) (a “Delisting”) and (y) exposure incurred in excess of $3.0 million in respect of proceedings in relation to the Demand and/or related proceedings and/or between such parties is deemed an Event of Default (as defined in the 2022 Credit Agreement) under the 2022 Credit Agreement.

In the fiscal year ended December 31, 2023, we recorded $2.2 million in interest expense related to the 2022 Credit Agreement. As of March 31, 2023, we had $35.0 million in aggregate principal amount of long-term debt outstanding under this debt agreement.

2022 Warrant Agreement

On June 30, 2022, in connection with entering into the 2022 Credit Agreement, we entered into a warrant purchase agreement with the Lenders under the 2022 Credit Agreement, pursuant to which we issued to the Lenders warrants to purchase up to an aggregate 3,779,018 shares (the “2022 Warrant Shares”) of our common stock, par value $0.001 per share, at an exercise price of $1.1114 per 2022 Warrant Share for a period of eight years following the issuance thereof, on and subject to the terms and conditions set forth in the warrants evidencing such rights (the “Warrants”).

On March 4, 2024, we entered into an amendment (the “Amendment”) to the 2022 Warrants and 2022 Warrant Purchase Agreement with Deerfield. Pursuant to the Amendment, (i) the 2022 Warrants were amended to remove Deerfield’s option to require us to repurchase the 2022 Warrants from Deerfield upon a Delisting, and to modify the volatility rate that would be used to calculate the Black-Scholes value of the 2022 Warrants that would apply to certain other transactions involving us pursuant to the 2022 Warrants, and (ii) the Warrant Purchase Agreement was amended to remove our obligation to take all commercially reasonable actions necessary to cause our common stock to remain listed on Nasdaq at all times during the term of the 2022 Warrants.

2022 Registration Rights Agreement

On June 30, 2022, in connection with the issuance of the Warrants, we also entered into a registration rights agreement (the “Registration Rights Agreement”) with the Lenders, pursuant to which we filed a shelf registration statement on Form S-3 (the “Registration Statement”) with the SEC to register the resale of certain securities held by the Lenders and their affiliates (the “Registrable Securities”). In addition, for a period of five years following the execution of the Registration Rights Agreement, or until all Registrable Securities are registered or no longer subject to restrictions on transfer (whichever is earlier), the Lenders will hold certain “piggy-back” registration rights with respect to registration statements filed during such period. We will generally pay all reasonable expenses incidental to its obligations and performance under the Registration Rights Agreement, other than underwriting discounts and commissions and such other charges.

Policies and Procedures for Related Party Transactions

Our Board of Directors adopted a written related party transaction policy in connection with our initial public offering, setting forth the policies and procedures for the review and approval or ratification of related party transactions. This policy covers any transaction, arrangement or relationship or any series of similar transactions, arrangements or relationships, in which we were or are to be a participant and a related party had or will have a direct or indirect material interest, as determined by the Audit Committee of our Board of Directors, including, without limitation, purchases of goods or services by or from the related party or entities in which the related party has a material interest, and indebtedness, guarantees of indebtedness or employment by us of a related party.

Transactions described in this section entered into during our fiscal year ended December 31, 2023 and December 31, 2022 were reviewed and approved pursuant to these policies and procedures. Certain other related party transactions described in this section occurred prior to adoption of this policy and as such, these transactions were not subject to the approval and review procedures set forth in the policy. However, these transactions were reviewed and approved by our Board of Directors.

HOUSEHOLDING OF PROXY MATERIALS

The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for Proxy Availability Notice or other proxy materials with respect to two or more stockholders sharing the same address by delivering a single Proxy Availability Notice or other proxy materials addressed to those stockholders. This process, which is commonly referred to as householding, potentially provides extra convenience for stockholders and cost savings for companies. Stockholders who participate in householding will continue to be able to access and receive separate proxy cards.

This year, a number of brokers with account holders who are our stockholders will be “householding” our proxy materials. A Proxy Availability Notice or proxy materials will be delivered in one single envelope to multiple stockholders sharing an address unless contrary instructions have been received from one or more of the affected stockholders. Once you have received notice from your broker that they will be householding communications to your address, householding will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in householding and would prefer to receive a separate Proxy Availability Notice or proxy materials, please notify your broker or contact Broadridge Financial Solutions, Inc. in writing: Attn: Householding Department, 51 Mercedes Way, Edgewood, NY 11717; or by telephone: (800) 542-1061. Stockholders who currently receive multiple copies of the Proxy Availability Notice or proxy materials at their address and would like to request householding of their communications should contact their broker. In addition, we will promptly deliver, upon written or oral request to the address or telephone number above, a separate copy of the Proxy Availability Notice or proxy materials to a stockholder at a shared address to which a single copy of the documents was delivered.
