PROXY STATEMENT

FOR THE ANNUAL MEETING OF STOCKHOLDERS TO BE HELD ON

DECEMBER 10, 2019

This proxy statement (this “Proxy Statement”) is being furnished to holders of ARCA biopharma, Inc. (sometimes referred to as the “Company,” “ARCA,” “we,” “us,” and “our”) common stock, par value $0.001 per share (the “Common Stock”). Proxies are being solicited on behalf of the Board of Directors of ARCA (the “Board of Directors” or the “Board”) to be used at the Annual Meeting of Stockholders (the “Annual Meeting”) to be held on Tuesday, December 10, 2019 at 9:00 a.m. Mountain time at the Denver Marriott Westminster, 7000 Church Ranch Blvd, Westminster, Colorado 80021 and at any postponement or adjournment thereof, for the purposes set forth in the Notice of Annual Meeting of Stockholders.

ARCA is using the Securities and Exchange Commission (the “SEC”) rule that allows companies to furnish their proxy materials over the Internet. As a result, we intend to mail to our stockholders a Notice of Internet Availability of Proxy Materials (the “Notice”) instead of a paper copy of the proxy materials (including the form of proxy, this Proxy Statement and our Annual Report on Form 10-K for the fiscal year ended December 31, 2018, filed with the SEC on February 27, 2019 (the “2018 Annual Report”), collectively, the “Proxy Materials”) on or about October 28, 2019. We will also provide access to our Proxy Materials over the Internet by October 28, 2019. By furnishing the Notice to our stockholders of record, you will not receive a printed copy of the Proxy Materials in the mail. Instead, the Notice instructs you on how to access and review all of the important information contained in the Proxy Statement and Annual Report electronically or to receive a printed version in the mail. The Notice also instructs you on how you may submit your proxy over the Internet, by toll-free number or in person at the Annual Meeting. After receiving the Notice, all stockholders can access the Proxy Materials over the Internet and request to receive a paper copy of the Proxy Materials by mail. Instructions on how to access the Proxy Materials over the Internet or to request a paper copy may be found on the Notice. In addition, the Notice contains instructions on how stockholders may request to receive Proxy Materials electronically by e-mail.

All stockholders may view and print ARCA’s proxy statement and the 2018 Annual Report, which are available at www.arcabio.com.

QUESTIONS AND ANSWERS ABOUT THESE PROXY MATERIALS AND VOTING

Why did I receive a notice regarding the availability of the Proxy Materials on the Internet?

As described above, pursuant to rules adopted by the SEC, we have elected to provide access to the Proxy Materials over the Internet. Accordingly, on or about October 28, 2019, we expect to send the Notice to ARCA’s stockholders of record. The Board of Directors is soliciting your proxy to vote at the Annual Meeting. All stockholders can access the Proxy Materials on the website referred to in the Notice or request to receive a printed or electronic set of the Proxy Materials. Instructions on how to access the Proxy Materials over the Internet or to request a printed copy may be found in the Notice.

How do I attend the Annual Meeting?

The meeting will be held on Tuesday, December 10, 2019 at 9 a.m. Mountain time at the Denver Marriott Westminster, 7000 Church Ranch Blvd, Westminster, Colorado 80021. Directions to the Annual Meeting may be found at www.arcabio.com. Information on how to vote in person at the Annual Meeting is discussed below.

Who can vote at the Annual Meeting?

Only stockholders of record at the close of business on October 14, 2019 will be entitled to vote at the Annual Meeting. On October 25, 2019, there were 1,594,070 shares of Common Stock outstanding and entitled to vote.

Stockholder of Record: Shares Registered in Your Name

If, on October 14, 2019, your shares were registered directly in your name with ARCA’s transfer agent, Computershare Trust Company N.A., then you are a stockholder of record. As a stockholder of record, you may vote in person 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 or return the proxy card we may mail to you to ensure your vote is counted.

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

If, on October 14, 2019, 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 Materials are being forwarded to you by that organization. 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 or other agent 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 in person at the meeting unless you request and obtain a valid proxy from your broker or other agent.

What am I voting on?

There are four matters scheduled for a vote:

➢

Election of two directors;

➢

Ratification of selection by the Audit Committee (the “Audit Committee”) of the Board of Directors of KPMG LLP (“KPMG”) as independent registered public accounting firm of the Company for its fiscal year ending December 31, 2019;

➢

Advisory approval of the compensation of the Company’s named executive officers, as disclosed in this proxy statement in accordance with SEC rules; and

➢

Advisory indication of the preferred frequency of stockholder advisory votes on the compensation of the Company’s named executive officers.

What if another matter is properly brought before the meeting?

The Board of Directors knows of no other matters that will be presented for consideration at the Annual Meeting. If any other matters are properly brought before the meeting, it is the intention of the persons named in the accompanying proxy to vote on those matters in accordance with their best judgment.

How do I vote?

You may either vote “For” each nominee to the Board of Directors or you may “Withhold” your vote for each nominee. With regard to your advisory vote on how frequently we should solicit stockholder advisory approval of executive compensation, you may vote for any one of the following: one year, two years or three years, or you may abstain from voting on that matter. For all other matters to be voted on, you may vote “For” or “Against” or abstain from voting. The procedures for voting are fairly simple:

Stockholder of Record: Shares Registered in Your Name

If you are a stockholder of record, you may vote in person 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 meeting, we urge you to vote by proxy to ensure your vote is counted. You may still attend the meeting and vote in person even if you have already voted by proxy.

➢

To vote in person, come to the Annual Meeting and we will give you a ballot when you arrive.

➢

To vote using the proxy card, simply complete, sign and date the proxy card that you may request or that we may elect to deliver at a later time and return it promptly in the envelope provided. If you return your signed proxy card to us before the Annual Meeting, we will vote your shares as you direct.

➢

To vote over the telephone, dial toll-free 1-800-652-VOTE (8683) using a touch-tone phone and follow the recorded instructions. You will be asked to provide the company number and control number found on the Notice. Your vote must be received by 1:00 a.m. Mountain Time on December 10, 2019 to be counted.

➢

To vote through the Internet, go to http://www.investorvote.com/ABIO to complete an electronic proxy card. You will be asked to provide the company number and control number from the Notice. Your vote must be received by 1:00 a.m. Mountain Time on December 10, 2019 to be counted.

Beneficial Owner: Shares Registered in the Name of Broker or Bank

If you are a beneficial owner of shares registered in the name of your broker, bank, or other agent, you should have received a Notice containing voting instructions from that organization rather than from ARCA. Simply follow the voting instructions in the Notice to ensure that your vote is counted. You may vote by telephone or over the Internet as instructed by your broker or bank. To vote in person at the Annual Meeting, you must obtain a valid proxy from your broker, bank, or other agent. Follow the instructions from your broker or bank included with these proxy materials, or contact your broker or bank to request a proxy form.

We provide Internet proxy voting to allow you to vote your shares online, with procedures designed to ensure the authenticity and correctness of your proxy vote instructions. However, please be aware that you must bear any costs associated with your access to the Internet, such as usage charges from Internet access providers and telephone companies.

How many votes do I have?

On each matter to be voted upon, you have one vote for each share of Common Stock you owned as of October 14, 2019.

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 nominee for director and “For” the ratification of KMPG as the Company’s independent registered public accounting firm for the fiscal year 2019, “For” the advisory approval of executive compensation and for “One Year” as the preferred frequency of advisory votes to approve executive compensation. If any other matter is properly presented at the meeting, your proxy holder (one of the individuals named on your proxy card) will vote your shares using his or her best judgment.

Who is paying for this proxy solicitation?

We will pay for the entire cost of soliciting proxies. In addition to these proxy materials, the directors and employees may also solicit proxies in person, by telephone, or by other means of communication. Directors and employees will not be paid any additional compensation for soliciting proxies. We may also reimburse brokerage firms, banks and other agents for the cost of forwarding proxy materials to beneficial owners.

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

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

Can I change my vote after submitting my proxy?

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

➢

You may submit another properly completed proxy card with a later date.

➢

You may grant a subsequent proxy by telephone or through the Internet.

➢

You may send a timely written notice that you are revoking your proxy to ARCA’s Secretary at 11080 CirclePoint Road, Suite 140, Westminster, Colorado 80020.

➢

You may attend the Annual Meeting and vote in person. Simply attending the meeting will not, by itself, revoke your proxy.

Your most current proxy card or telephone or Internet proxy is the one that is counted.

If your shares are held by your broker or bank as a nominee or agent, you should follow the instructions provided by your broker or bank.

When are stockholder proposals due for next year’s annual meeting?

To be considered for inclusion in next year’s proxy materials, your proposal must be submitted in writing by June 30, 2020, to ARCA’s Secretary at 11080 CirclePoint Road, Suite 140, Westminster, Colorado, 80020. If you wish to submit a proposal that is not to be included in next year’s proxy materials or nominate a director, you must do so by no earlier than September 11, 2020, and no later than October 11, 2020. You are also advised to review the Company’s Bylaws, which contain additional requirements about advance notice of stockholder proposals and director nominations.

How are votes counted?

Votes will be counted by the inspector of election appointed for the meeting. For Proposal 1, to elect new directors, votes “For” and “Withhold” will be counted. For Proposals 2 and 3, votes “For” and “Against”, abstentions will be counted. Abstentions will be counted towards the vote total for Proposals 2 and 3, and will have the same effect as “Against” votes. For Proposal 4, regarding frequency of stockholder advisory votes to approve executive compensation, abstentions will have no effect and will not be counted towards the vote total. Broker non-votes have no effect and will not be counted towards the vote total for any proposal.

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 or 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 or nominee holding the shares. If the beneficial owner does not provide voting instructions, the broker or nominee can still vote the shares with respect to matters that are considered to be “routine,” but not with respect to “non-routine” matters. Under the rules and interpretations of the New York Stock Exchange, “non-routine” matters are matters that may substantially affect the rights or privileges of stockholders, such as mergers, stockholder proposals and elections of directors, even if not contested.

How many votes are needed to approve each proposal?

➢

Proposal No. 1, for the election of directors. For this proposal, the two nominees receiving the most “For” votes (from the holders of votes of shares present in person or represented by proxy and entitled to vote on the election of directors) will be elected. Only votes “For” or “Withheld” votes will affect the outcome. Broker non-votes will have no effect.

➢

Proposal No. 2, to ratify the selection of KPMG as the Company’s independent registered public accounting firm for fiscal year 2019. This proposal must receive “For” votes from the holders of a majority of shares present and entitled to vote either in person or represented by proxy. If you “Abstain” from voting, it will have the same effect as an “Against” vote. Broker non-votes will have no effect.

➢

Proposal No. 3, an advisory approval of the compensation of the Company’s named executive officers. This proposal must receive “For” votes from the holders of a majority of shares present and entitled to vote either in person or represented by proxy. If you “Abstain” from voting, it will have the same effect as an “Against” vote. Broker non-votes will have no effect.

➢

Proposal No. 4, the advisory vote on the frequency of stockholder advisory votes on executive compensation, the frequency receiving the highest number of affirmative votes from the holders of shares present in person or represented by proxy and entitled to vote at the Annual Meeting will be considered the frequency preferred by the stockholders. Broker non-votes and abstentions will have no effect.

What is the quorum requirement?

A quorum of stockholders is necessary to hold a valid meeting. A quorum will be present if stockholders holding a majority of the outstanding shares entitled to vote are present at the meeting in person or represented by proxy. On the record date, October 14, 2019, there were 1,594,070 shares of Common Stock outstanding and entitled to vote. Thus, the holders of 797,035 shares of Common Stock must be present at the meeting in person or represented by proxy at the meeting to have a quorum.

Your shares will be counted towards the quorum only if you submit a valid proxy (or one is submitted on your behalf by your broker, bank or other nominee) or if you vote in person at the meeting. Abstentions and broker non-votes, if any, will be counted towards the quorum requirement. If there is no quorum, the holders of a majority of shares present at the meeting in person or represented by proxy may adjourn the meeting to another date.

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 within four business days after the Annual Meeting. If final voting results are not available to us in time to file a Form 8-K within four business days after the meeting, we intend to file a Form 8‑K to publish preliminary results and, within four business days after the final results are known to us, file an additional Form 8-K to publish the final results. Additionally, if this Form 8-K does not include the Company’s decision regarding the results of the vote on Proposal 4 included in these Proxy Materials, then we will file a Form 8-K on this topic no more than 150 calendar days after the end of the Annual Meeting, but in no event later than 60 calendar days prior to the deadline for submissions of stockholders proposals under Rule 14a-8 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

What proxy materials are available on the internet?

We will make all of the Proxy Materials available on the Internet at http://www.investorvote.com/ABIO, beginning on or about October 28, 2019, and permit voting via the Internet and by telephone as of that date.

NO PERSON IS AUTHORIZED TO GIVE ANY INFORMATION OR TO MAKE ANY REPRESENTATION OTHER THAN THOSE CONTAINED IN THIS PROXY STATEMENT, AND, IF GIVEN OR MADE, SUCH INFORMATION MUST NOT BE RELIED UPON AS HAVING BEEN AUTHORIZED. THE DELIVERY OF THIS PROXY STATEMENT SHALL, UNDER NO CIRCUMSTANCES, CREATE ANY IMPLICATION THAT THERE HAS BEEN NO CHANGE IN THE AFFAIRS OF ARCA SINCE THE DATE OF THIS PROXY STATEMENT.

Proposal No. 1

Election of Board of Directors

The Company’s Amended and Restated Certificate of Incorporation provides that the Board of Directors is divided into three classes to provide for staggered terms and that each director will serve for a term of three years or less, depending on the class to which the Board of Directors has assigned a director not previously elected by the stockholders. There are currently no vacancies on the Board of Directors. Vacancies on the Board of Directors may be filled only by persons elected by a majority of the remaining directors. A director elected by the Board of Directors to fill a vacancy in a class, including vacancies created by an increase in the number of directors, shall serve for the remainder of the full term of that class and until the director’s successor is duly elected and qualified. The Company may reduce or increase the size of the Board of Directors by resolution adopted by the affirmative vote of a majority of the directors.

There are currently two Class I directors whose terms expire at the annual stockholders’ meeting in 2019, two Class II directors whose terms expire at the annual stockholders’ meeting in 2020 and two Class III directors whose terms expire at the annual meeting in 2021. The Board of Directors has nominated two Class I directors, Drs. Linda Grais and Anders Hove, for election to the Board of Directors, for a three-year term ending on the date of the annual stockholders meeting in 2022 or until their successors are duly elected and qualified or appointed.

If elected at the Annual Meeting, Drs. Grais and Hove would serve until the 2022 annual stockholders meeting and until their successors have been duly elected and qualified, or, if sooner, until the director’s death, resignation or removal. It is the Company’s policy to encourage directors and nominees for director to attend the Annual Meeting. Five of the Company’s directors then on the Board of Directors attended the 2018 Annual Meeting of Stockholders in person, and one attended by telephone.

Directors are elected by a plurality of the votes of the holders of shares present in person 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. Each person nominated for election has agreed to serve if elected. The Company’s management has no reason to believe that either nominee will be unable to serve.

Director Qualifications and Diversity

The below paragraphs provide information, as of the date of this proxy statement, about each nominee and current members of the Board of Directors, including age, all positions currently held, principal occupation and business experience for the past five years. In addition to the information presented regarding each nominee’s specific experience, qualifications, attributes and skills that led the Board of Directors to conclude that such director or nominee should be able to serve as a director, the Board of Directors also believes that all of the directors and nominees have a reputation of integrity, honesty and adherence to high ethical standards. They each have demonstrated business acumen and an ability to exercise sound judgment as well as a commitment to service to ARCA and the Board of Directors.

Our Nominating and Corporate Governance Committee of the Board of Directors (the “Nominating and Corporate Governance Committee”) considers diversity in the director identification and nomination process. The Nominating and Corporate Governance Committee seeks nominees with a broad diversity of experience, professions, skills, geographic representation and backgrounds. The Nominating and Corporate Governance Committee does not assign specific weights to particular criteria and no particular criterion is necessarily applicable to all prospective nominees. We believe that the backgrounds and qualifications of the directors, considered as a group, should provide a significant composite mix of experience, knowledge and abilities that will allow the Board of Directors to fulfill its responsibilities. Nominees are not discriminated against on the basis of race, religion, national origin, sexual orientation, disability or any other basis proscribed by law.

Nominee for Election for a Three-year Term Expiring at the 2022 Annual Meeting

The Board Of Directors Recommends

A Vote In Favor Of The Named Nominees.

Linda Grais, M.D.

Dr. Grais, age 63, has served as a member of the Board of Directors since May 2007. Dr. Grais has been a director of Ocera Therapeutics, Inc., a public biopharmaceutical company, since January 2008 and became President and Chief Executive Officer of Ocera in June 2012, and served in that role until Ocera’s acquisition by Mallinckrodt Pharmaceuticals in December 2017. Dr. Grais served as a Managing Member at InterWest Partners, a venture capital firm from May 2005 until February 2011. From July 1998 to July 2003, Dr. Grais was a founder and executive vice president of SGX Pharmaceuticals Inc., a drug discovery company. Prior to that, she was a corporate attorney at Wilson Sonsini Goodrich & Rosati, where she practiced in such areas as venture financings, public offerings and strategic partnerships. Before practicing law, Dr. Grais worked as an assistant clinical professor of Internal Medicine and Critical Care at the University of California, San Francisco. Dr. Grais received a B.A. from Yale University, magna cum laude, and Phi Beta Kappa, an M.D. from Yale Medical School and a J.D. from Stanford Law School. Since September 2015, Dr. Grais has served on the board of PRA Health Sciences, a public contract research organization. Dr. Grais also joined the boards of Corvus Pharmaceuticals and Zosano Pharma Corp., both publicly traded pharmaceutical companies, in January 2019. We believe Dr. Grais is an appropriate member of the Board of Directors because of her diverse training and experience as both a medical doctor and a lawyer, her experience as a founder and senior executive of a pharmaceutical company, and her experience as an investor in new life sciences companies. She also has extensive experience with and knowledge of the Company's business from her service on the Board of Directors of the Company since 2007.

Mr. Hove was a member of the boards of directors of Anacor Pharmaceuticals, a publicly traded pharmaceutical company, from 2005 until its acquisition by Pfizer in June 2016, and Edge Therapeutics, a publicly traded biotechnology company, from 2015 to 2016.

He received a M.Sc. in Biotechnology Engineering from the Technical University of Denmark, an M.D. from the University of Copenhagen and an M.B.A. from the Institut Européen d'Administration des Affaires. We believe Dr. Hove is an appropriate member of the Company’s Board of Directors, given his extensive training and experience as a medical doctor and masters of business administration, an executive in the pharmaceutical industry, and as an investor in biotechnology companies.

Information Regarding the Board of Directors and Corporate Governance

Independence of The Board of Directors

As required under the Nasdaq Stock Market (“Nasdaq”) listing standards, a majority of the members of a listed company’s board of directors must qualify as “independent,” as affirmatively determined by the board of directors. Our Board of Directors consults with the Company’s counsel to ensure that the Board of Directors’ determinations are consistent with relevant securities and other laws and regulations regarding the definition of “independent,” including those set forth in pertinent listing standards of the Nasdaq, as in effect from time to time.

Consistent with these considerations, after review of all relevant identified transactions or relationships between each director, or any of his or her family members, and the Company, its senior management and its independent registered public accounting firm, the Board of Directors has affirmatively determined that the following five directors are independent directors within the meaning of the applicable Nasdaq listing standards: Mr. Conway, Dr. Grais, Mr. Mitchell, Dr. Hove and Dr. Woosley. In making this determination, the Board of Directors found that none of the directors or nominees for director had a material or other disqualifying relationship with the Company. Dr. Bristow, the Company’s President and Chief Executive Officer, is not an independent director by virtue of his employment relationship with the Company.

Board Leadership Structure

The Company has structured its Board of Directors in a way that the Company believes effectively serves its objectives of corporate governance and management oversight. The Company separates the roles of Chief Executive Officer and Chairman of the Board of Directors in recognition of the differences between the two roles. The Company believes that the Chief Executive Officer should be responsible for the day to day leadership and performance of the Company, while the Chairman of the Board of Directors should work with the Chief Executive Officer and the rest of the Board of Directors to set the strategic direction for the Company and provide guidance to, and oversight of the Chief Executive Officer. The Chairman also sets the agenda for meetings of the Board of Directors and presides over them.

Mr. Conway, who is an independent director, was elected Chairman of the Board of Directors in 2014. In this capacity, Mr. Conway, among other things, calls and presides over Board meetings, including meetings of the independent directors, and sets meeting agendas. In this role, Mr. Conway can effectively coordinate between the Board of Directors and management regarding risk management issues and the implementation of appropriate responses, and can help ensure the effective independent functioning of the Board of Directors in its oversight responsibilities. Accordingly, the Chairman has substantial ability to shape the work of the Board of Directors.

Role of the Board of Directors in Risk Oversight and Risk Management

One of the Board of Directors’ key functions is informed oversight of the Company’s risk management process. The Board of Directors does not have a standing risk management committee, but rather administers this oversight function directly through the Board of Directors as a whole, as well as through various standing committees of the Board of Directors that address risks inherent in their respective areas of oversight. In particular, while the Board of Directors is responsible for monitoring and assessing strategic risk exposure, the Audit Committee has the responsibility to consider and discuss the major financial risk exposures and the steps management has taken to monitor and control these exposures, including guidelines and policies to govern the process by which risk assessment and management is undertaken. The Audit Committee also monitors compliance with legal and regulatory requirements, in addition to oversight of the performance of ARCA’s accounting and financial reporting processes. The Nominating and Corporate Governance Committee monitors the effectiveness of the corporate governance guidelines, including whether they are successful in preventing illegal or improper liability-creating conduct. The Compensation Committee of the Board of Directors (the “Compensation Committee”) assesses and monitors whether any compensation policies and programs have the potential to encourage excessive risk-taking. The entire Board of Directors and its committees address risk management issues from time-to-time and at least annually meet with the employees responsible for risk management in the committees’ respective areas of oversight. Both the Board of Directors as a whole and the various standing committees receive periodic reports from the employees responsible for risk management, as well as incidental reports as matters may arise. It is the responsibility of the committee chairs to report findings regarding material risk exposures to the Board of Directors as quickly as possible.

Meetings of The Board of Directors

The Board of Directors met eight times during the 2018 fiscal year. The independent members of the Board of Directors met separately as a group at four of the board meetings in 2018. All members of the Board of Directors attended at least 75% of the meetings of the Board of Directors and at least 75% the meeting of the committees of the Board of Directors of which each director was a member.

Information Regarding Committees of the Board of Directors

The Board of Directors has three standing committees: The Audit Committee, the Compensation Committee, and the Nominating and Corporate Governance Committee. The following table provides membership and meeting information for the fiscal year ended December 31, 2018, for each of the committees of the Board of Directors:

Name	Audit	Compensation	Nominating and Corporate Governance

*	Committee Chairperson.

Below is a description of each committee of the Board of Directors. 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 of Directors has determined that each member of each committee meets the applicable Nasdaq 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 regarding the Company.

Audit Committee

The Audit Committee was established by the Board of Directors in accordance with Section 3(a)(58)(A) of the Exchange Act, to oversee the Company’s corporate accounting and financial reporting processes and audits of its financial statements. For this purpose, the Audit Committee performs several functions. The Audit Committee evaluates the performance of and assesses the qualifications of the independent registered public accounting firm; determines and approves the engagement of the independent registered public accounting firm; determines whether to retain or terminate the existing independent registered public accounting firm or to appoint and engage a new independent registered public accounting firm; reviews and approves the retention of the independent registered public accounting firm to perform any proposed permissible non-audit services; monitors the rotation of partners of the independent registered public accounting firm on the Company’s audit engagement team as required by law; reviews and approves or rejects transactions between the company and any related persons; confers with management and the independent registered public accounting firm regarding the effectiveness of internal controls over financial reporting; establishes procedures, as required under applicable law, for the receipt, retention and treatment of complaints received by the Company regarding accounting, internal accounting controls or auditing matters and the confidential and anonymous submission by employees of concerns regarding questionable accounting or auditing matters; and meets to review the Company’s annual audited financial statements and quarterly financial statements with management and the independent registered public accounting firm, including a review of the Company’s disclosures under the “Management’s Discussion and Analysis of Financial Condition and Results of Operations” discussion in its Annual Reports on Form 10-K and Quarterly Reports on Form 10-Q. The Audit Committee is composed of three directors: Mr. Conway (chair), Mr. Mitchell and Dr. Grais. The Audit Committee met four times during the fiscal year. The Board of Directors has adopted a written charter of the Audit Committee that is available to stockholders on the Company’s website at www.arcabio.com.

The Board of Directors reviews the Nasdaq listing standards definition of independence for audit committee members on an annual basis and has determined that all members of the Audit Committee are independent (as independence is currently defined in Rule 5605(c)(2)(A)(i) and (ii) of the Nasdaq listing standards).The Board of Directors has also determined that Mr. Conway qualifies as an “audit committee financial expert,” as defined in applicable SEC rules. The Board of Directors made a qualitative assessment of Mr. Conway’s level of knowledge and experience based on several factors, including his prior experience, business acumen and independence.

Report of the Audit Committee of the Board of Directors¹

The Audit Committee has reviewed and discussed the audited financial statements for the fiscal year ended December 31, 2018, with management of the Company. The Audit Committee has discussed with the independent registered public accounting firm the matters required to be discussed by Public Company Accounting Oversight Board (“PCAOB”) Auditing Standard No. 1301, Communications with Audit Committees. The Audit Committee has also received the written disclosures and the letter from the independent registered public accounting firm required by applicable requirements of the PCAOB regarding the independent registered public accounting firm’s communications with the Audit Committee concerning independence, and has discussed with the independent registered public accounting firm the accounting firm’s independence. Based on the foregoing, the Audit Committee has recommended to the Board of Directors that the audited financial statements be included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2018.

Mr. Robert Conway

Mr. Dan Mitchell

Dr. Linda Grais

Compensation Committee

The Compensation Committee is currently composed of three directors: Mr. Conway, Dr. Grais (chair) and Dr. Woosley. All members of the Compensation Committee are independent, as independence is currently defined in Rule 5605(a)(2) of the Nasdaq listing standards. The Compensation Committee met one time during the fiscal year. The Compensation Committee has adopted a written charter that is available to stockholders on the Company’s website at www.arcabio.com.

The Compensation Committee of the Board of Directors acts on behalf of the Board of Directors to review, adopt and oversee the Company’s compensation strategy, policies, plans and programs, including:

•

overseeing succession planning for senior management of the Company, including a review of the performance and advancement potential of current and future senior management and succession plans for each and recommending, as appropriate, the retention of potential succession candidates;

•

assessing the overall compensation structure of the Company and evaluating and recommending changes to the Company’s compensation philosophies and strategies;

•

reviewing and approving performance-based compensation plans or programs, including establishing goals and targets, applicable to the Chief Executive Officer and other members of the management team;

The material in this report is not “soliciting material,” is not deemed “filed” with the SEC and is not to be incorporated by reference in any filing of the Company under the Securities Act of 1933, as amended, or the Exchange Act, whether made before or after the date hereof and irrespective of any general incorporation language in any such filing.

•

administering, reviewing, and approving all executive compensation programs or plans, and all of the Company’s incentive compensation and stock plans and awards thereunder of the Company, including amendments to the programs, plans or awards made thereunder; and

•

preparing and approving the Report of the Compensation Committee to be included as part of the Company’s annual meeting proxy statement, to the extent required.

Compensation Committee Processes and Procedures

The Compensation Committee meets on a regular basis as it deems appropriate. The agenda for each meeting is usually developed by the Chair of the Compensation Committee. The Compensation Committee meets regularly in executive session. However, from time to time, various members of management and other employees as well as outside advisors or consultants may be invited by the Compensation Committee to make presentations, to provide financial or other background information or advice or to otherwise participate in Compensation Committee meetings. The Chief Executive Officer may not participate in, or be present during, any deliberations or determinations of the Compensation Committee regarding his compensation or individual performance objectives. The Compensation Committee has the sole authority to retain compensation consultants to assist in its evaluation of executive and director compensation, including the authority to approve the consultant’s reasonable fees and other retention terms. In general, the Compensation Committee has set executive compensation to be in line with peer companies identified by the Compensation Committee and to incentivize the Company’s executive officers in achieving the Company’s short- and long-term corporate goals.

In setting 2017 and 2018 base salary and cash bonus award amounts for the Named Executive Officers (as defined below), the Compensation Committee considered peer group data and factors specific to the Company, and targeted cash compensation to be consistent with these metrics. For the fiscal year ended December 31, 2017, the Compensation Committee recommended, and the Board of Directors approved, a base salary of $295,359 for Dr. Bristow, the Company’s President and Chief Executive Officer, a base salary of $294,170 for Mr. Keuer, the Company’s Chief Operating Officer, and a base salary of $288,683 for Mr. Ozeroff, the Company’s Senior Vice President and General Counsel. In March 2018, the Compensation Committee recommended, and the Board of Directors approved cash bonuses based on previous performance for the Named Executive Officers for their performance in the fiscal year ended December 31, 2017. There were no changes to the Named Executive Officers’ salaries for 2018 or 2019. Additionally, the Compensation Committee recommended that no bonuses be paid to the Named Executive Officers for performance in the fiscal year ended December 31, 2018 and has not approved a cash bonus plan for performance in the fiscal year ended December 31, 2019.

In May 2019, the Named Executive Officers agreed to a voluntary 10% salary reduction for the remainder of 2019. As a result of this reduction, the base salary to be paid to the Named Executive Officer’s for 2019 is as follows:

•

Michael R. Bristow, President and Chief Executive Officer, $273,797;

•

Thomas A. Keuer, Chief Operating Officer, $272,700; and

•

Christopher D. Ozeroff, Secretary, Senior Vice President and General Counsel, $267,609.

The foregone portion of any salary otherwise owed to each Named Executive Officer shall not be paid without the prior approval of the Board of Directors, provided, that such foregone amounts shall be included in each Named Executive Officer’s base salary for purposes of calculating any severance amounts which may be owed in the future under the terms of such Named Executive Officer’s employment agreement with the Company.

Historically, the Compensation Committee has made most of the significant adjustments to annual compensation, determined bonus and equity awards and established new performance objectives at one or more meetings held during the first quarter of the year. However, the Compensation Committee also considers matters related to individual compensation, such as compensation for new executive hires, as well as high-level strategic issues, such as the efficacy of the Company’s compensation strategy, potential modifications to that strategy and new trends, plans or approaches to compensation, at various meetings throughout the year. Generally, the Compensation Committee’s process comprises two related elements: the determination of compensation levels and the establishment of performance objectives for the current year.

The Compensation Committee reviews and approves the compensation of the Chief Executive Officer and the other executive officers of the Company, including annual base salaries, annual and long-term incentive or bonus awards, employment agreements, and severance and change in control agreements/provisions, in each case as, when and if appropriate, and any special or supplemental benefits. For executives other than the Chief Executive Officer, the Compensation Committee solicits and considers evaluations and recommendations submitted to the Compensation Committee by the Chief Executive Officer. The Compensation Committee evaluates the performance of the Chief Executive Officer in light of Company and individual goals and objectives, and makes appropriate recommendations for improving performance. In performing the evaluation, the Chair of the Compensation Committee may solicit comments from the other non-employee members of the Board of Directors and lead the Board of Directors in an overall review of the Chief Executive Officer’s performance in an executive session of non-employee members of the Board of Directors. If the compensation for the Chief Executive Officer or any other executive officer is governed by an employment agreement, the Compensation Committee approves such employment agreement and any amendments thereto.

For all executives as part of its deliberations, the Compensation Committee may review and consider, as appropriate, materials such as financial reports and projections, operational data, tax and accounting information, tally sheets that set forth the total compensation that may become payable to executives in various hypothetical scenarios, executive and director stock ownership information, company stock performance data, analyses of historical executive compensation levels and current Company-wide compensation levels.

The Compensation Committee also considers the results of any “say-on-pay” vote of the Company’s stockholders with regard to the compensation of the Company’s executive officers when making compensation decisions. At the 2016 annual meeting of stockholders, the Company’s stockholders approved, on an advisory basis, the compensation of the Company’s named executive officers as described in the proxy statement for such annual meeting. The Compensation Committee believes that this advisory vote supports that the Company’s current compensation practices are aligned with the best interests of stockholders and anticipates taking into account the results of the advisory vote included as Proposal 3 in these Proxy Materials (and any subsequent advisory vote on executive compensation) when making compensation decisions in the future.

Nominating and Corporate Governance Committee

The Nominating and Corporate Governance Committee is responsible for identifying, reviewing and evaluating candidates to serve as directors of the Company (consistent with criteria approved by the Board of Directors), reviewing and evaluating incumbent directors, recommending to the Board of Directors candidates for election to the Board of Directors, making recommendations to the Board of Directors regarding compensation for service on the Board of Directors and the committees thereof, making recommendations to the Board of Directors regarding the membership of the committees of the Board of Directors, assessing the performance of the Board of Directors and developing a set of corporate governance principles for the Company. The Nominating and Corporate Governance Committee is composed of three directors: Dr. Hove, Mr. Mitchell and Dr. Woosley (chair). All members of the Nominating and Corporate Governance Committee in 2018 were independent (as independence is currently defined in Rule 5605(a)(2) of the Nasdaq listing standards). The Nominating and Corporate Governance Committee met three times during the 2018 fiscal year. The Nominating and Corporate Governance Committee has adopted a written charter that is available to stockholders on the Company’s website at www.arcabio.com.

The Nominating and Corporate Governance Committee periodically reviews the compensation of non-employee Directors for service on the Board of Directors and committees thereof. In 2015, the Nominating and Corporate Governance Committee began a review of its Director compensation levels considering general market conditions in the life science industry, and in comparison to other clinical stage biopharmaceutical companies, and in early 2016, the Committee recommended, and the Board of Directors approved, revised compensation for non-employee Directors, discussed in “Director Compensation” below. Since adoption of this policy, the Nominating and Corporate Governance Committee has reviewed Director compensation on an annual basis and has not made any changes.

The Board of Directors has adopted a process for identifying and evaluating director nominees, including stockholder nominees. Before recommending an individual to the Board of Directors for membership on the Board of Directors, the Nominating and Corporate Governance Committee canvasses its members and the Company’s management team for potential candidates for the Board of Directors. The Nominating and Corporate Governance Committee also uses its network of contacts to identify potential candidates and, if it deems appropriate, may also engage a professional search firm. The Nominating and Corporate Governance Committee will consider stockholders’ recommendations for nominees to serve as director if notice is timely received by the Secretary of the Company. Candidates nominated by stockholders will be evaluated in the same manner as other candidates. The Nominating and Corporate Governance Committee keeps the Board of Directors apprised of its discussions with potential nominees, and the names of potential nominees received from its current directors, management, and stockholders, if the stockholder notice of nomination is timely made.

Although the Board of Directors has not adopted a fixed set of minimum qualifications for candidates for membership on the Board of Directors, the Nominating and Corporate Governance Committee generally considers several factors in its evaluation of a potential member, such as the candidate’s education, professional background and field of expertise including industry or academic experience in the pharmaceutical and biotechnology fields, experience in corporate governance and management, the reasonable availability of the potential member to devote time to the affairs of the Company, as well as any other criteria deemed relevant by the Board of Directors or the Nominating and Corporate Governance Committee. However, the Nominating and Corporate Governance Committee retains the right to modify these qualifications from time to time. Candidates for director nominees are reviewed in the context of the current composition of the Board of Directors, the operating requirements of the Company and the long-term interests of stockholders. In conducting this assessment, the Nominating and Corporate Governance Committee typically considers diversity, age, skills and such other factors as it deems appropriate given the current needs of the Board of Directors and the Company, to maintain a balance of knowledge, experience and capability. The Nominating and Corporate Governance Committee believes it is essential that Board of Directors members come from a variety of backgrounds and experiences.

In the case of incumbent directors whose terms of office are set to expire, the Nominating and Corporate Governance Committee reviews these directors’ overall contributions to the Company and the Board of Directors during their terms, including level of attendance, level of participation, quality of performance and contribution to the Board of Directors’ responsibilities and actions, and any relationships and transactions that might impair the directors’ independence. In the case of new director candidates, the Nominating and Corporate Governance Committee also determines whether the nominee is independent for Nasdaq and SEC purposes, which determination is based upon applicable Nasdaq listing standards, applicable SEC rules and regulations and the advice of counsel, if necessary. The Nominating and Corporate Governance Committee conducts any appropriate and necessary inquiries into the backgrounds and qualifications of possible candidates after considering the function and needs of the Board of Directors. The Nominating and Corporate Governance Committee meets to discuss and consider the candidates’ qualifications and then determines whether to recommend a nominee to the Board of Directors by majority vote.

Stockholders who wish to recommend individuals for consideration by the Nominating and Corporate Governance Committee to become nominees for election to the Board of Directors may do so by delivering a written recommendation to the Nominating and Corporate Governance Committee addressed to the Corporate Secretary, between 60 and 90 days before the one year anniversary date of ARCA’s last annual meeting of stockholders. Recommendations must include the full name of the proposed nominee, a description of the proposed nominee’s business experience for at least the previous five years, complete biographical information, a description of the proposed nominee’s qualifications as a director, and a representation that the recommending stockholder is a beneficial or record owner of ARCA’s stock. Any such submission must be accompanied by the written consent of the proposed nominee to be named as a nominee and to serve as a director if elected. To date, the Nominating and Corporate Governance Committee has not rejected a timely director nominee from a stockholder.

In 2018, the Nominating and Corporate Governance Committee did not pay any fees to assist in the process of identifying or evaluating director candidates.

Stockholder Communications With The Board Of Directors

Stockholders who wish to communicate with the Board of Directors may do so by e-mail by using the following email address: directors@arcabio.com; or by mail by following the directions as set forth on ARCA’s website at www.arcabio.com, under the section titled “Corporate Governance” and the subsection titled “Governance Documents”.

Code of Business Conduct and Ethics

The Company has adopted the ARCA biopharma, Inc. Code of Business Conduct and Ethics that applies to all officers, directors and employees. The Code of Business Conduct and Ethics is available on the Company’s website at www.arcabio.com. If the Company makes any substantive amendments to the Code of Business Conduct and Ethics or grants any waiver from a provision of the Code of Business Conduct and Ethics to any executive officer or director, the Company will promptly disclose the nature of the amendment or waiver on its website and file any current report on Form 8-K required by applicable law or Nasdaq listing standards.

Proposal 2

Ratification of Selection of the Independent Registered Public Accounting Firm

The Audit Committee has selected KPMG as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2019, and has further directed that management submit the selection of the independent registered public accounting firm for ratification by the stockholders at the Annual Meeting. KPMG has audited the Company’s fiscal year financial statements since 2006. Representatives of KPMG are expected to be present at the Annual Meeting. They will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions.

Neither the Company’s Bylaws nor other governing documents or law require stockholder ratification of the selection of KPMG as the Company’s independent registered public accounting firm. However, the Board of Directors 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 Audit Committee will reconsider whether to retain that firm. Even if the selection is ratified, the Audit Committee in its discretion may direct the appointment of a different independent registered public accounting firm at any time during the year if they determine that such a change would be in the best interests of the Company and its stockholders.

The affirmative vote of the holders of a majority of the shares present in person or represented by proxy and entitled to vote at the Annual Meeting will be required to ratify the selection of KPMG. Broker non-votes are counted towards a quorum, but are not counted for any purpose in determining whether this matter has been approved.

Principal Accountant Fees and Services

The following table represents aggregate fees billed, or expected to be billed, to us for the fiscal years ended December 31, 2018 and December 31, 2017, by KPMG LLP, our independent registered public accounting firm.

Audit-related Fees		—		—
Tax Fees		—		—
All Other Fees		—		—
Total Fees	$	$154,500	$	193,500

(1)

All fees described above were approved by the Audit Committee.

Pre-Approval Policies and Procedures

The above services performed by the independent registered public accounting firm were pre-approved in accordance with the pre-approval policy and procedures adopted by the Audit Committee. This policy describes the permitted audit, audit-related, tax, and other services that our independent registered public accounting firm may perform. The policy also requires that our independent registered public accounting firm provide in writing:

•

an annual description of all relationships between the independent registered public accounting firm and the client that may reasonably be thought to bear on independence;

•

confirm that, in the independent registered public accounting firm’s professional judgment, the independent registered public accounting firm is independent of the client under SEC requirements;

•

discuss with the Audit Committee the independent registered public accounting firm’s independence and the potential effects on its independence of performing any non-audit related services.

The services expected to be performed by our independent registered public accounting firm during the subsequent fiscal year are presented to the Audit Committee for pre-approval. Any pre-approval must describe, in writing, the particular service or category of services.

Requests for audit, audit-related, tax, and other services not contemplated by those pre-approved services must be submitted to the Audit Committee for specific pre-approval. Generally, pre-approval is considered at the Audit Committee’s regularly scheduled meetings. However, the authority to grant specific pre-approval between meetings, as necessary, has been delegated to the chairman of the Audit Committee. If the chairman is not available, the other two Audit Committee members together have the authority to grant specific pre-approval between meetings. The chairman or the other members must update the Audit Committee at the next regularly scheduled meeting of any services that were granted specific pre-approval.

The Audit Committee pre-approved all audit related services rendered in 2018 and did not rely on the waiver of pre-approval requirement provided by paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X promulgated under the Exchange Act .

The Board Of Directors Recommends

A Vote In Favor Of Proposal 2.

Proposal 3

Advisory Vote on Executive Compensation

Under the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”), and Section 14A of the Exchange Act, the Company’s stockholders are entitled to vote to approve, on an advisory basis, the compensation of the Named Executive Officers as disclosed in this proxy statement in accordance with SEC rules. This vote is not intended to address any specific item of compensation, but rather the overall compensation of the Named Executive Officers and the philosophy, policies and practices described in this proxy statement.

At the 2013 annual meeting of stockholders, the stockholders indicated their preference that the Company solicit a non-binding advisory vote on the compensation of the Named Executive Officers, commonly referred to as a “say-on-pay vote,” every three years. The Board of Directors has adopted a policy that is consistent with that preference.

The Company has designed its executive compensation program to attract, motivate, reward and retain the senior management talent required to achieve our corporate objectives and to increase long-term stockholder value.

The compensation of the Named Executive Officers subject to the vote is disclosed in the Executive Compensation discussion below, the compensation tables, and the related narrative disclosure contained in this proxy statement.

Accordingly, the Board of Directors is asking the stockholders to indicate their support for the compensation of the Named Executive Officers as described in this proxy statement by casting a non-binding advisory vote “FOR” the following resolution:

“RESOLVED, that the compensation paid to the Company’s named executive officers, as disclosed pursuant to Item 402 of Regulation S-K, including the Executive Compensation discussion below, compensation tables and narrative discussion, is hereby APPROVED.”

This vote is advisory, it is not binding on the Board of Directors. Nevertheless, the views expressed by the stockholders, whether through this vote or otherwise, are important to management and the Board of Directors and, accordingly, the Board of Directors and the Compensation Committee intend to consider the results of this vote in making determinations in the future regarding executive compensation arrangements.

Advisory approval of this proposal requires the vote of the holders of a majority of the shares present in person or represented by proxy and entitled to vote at the annual meeting. Unless the Board of Directors decides to modify its policy regarding the frequency of soliciting say-on-pay votes, the next scheduled say-on-pay vote will be at the 2022 annual meeting of stockholders.

A Vote In Favor Of Proposal 3

Proposal 4

Advisory Vote on the Frequency of Solicitation of
the Advisory Vote on Executive Compensation

The Dodd-Frank Act and Section 14A of the Exchange Act enable the Company’s stockholders to indicate their preference regarding how frequently the Company should solicit a non-binding advisory vote on the compensation of the Company’s named executive officers as disclosed in the Company’s proxy statements. Currently, consistent with the preference expressed by the stockholders at the Company’s 2013 annual meeting of stockholders, the policy of the Board of Directors is to solicit a say-on-pay vote every three years. Accordingly, the Company is asking stockholders to indicate whether they would prefer an advisory vote every year, every other year or every three years or abstaining from voting.

After considering the benefits and consequences of each alternative, the Board of Directors recommends that the advisory vote on the compensation of the Company’s named executive officers be submitted to the stockholders every year.

The Board of Directors believes that an annual advisory vote on the compensation of the Company’s named executive officers is most consistent with its approach to compensation. These reasons include our beliefs that:

•

it allows stockholders to provide direct input on the Company’s compensation philosophy, policies and practices as disclosed in the proxy statement each year;.

•

it provides the Compensation Committee with the opportunity to evaluate its compensation decisions by taking into account timely feedback provided by stockholders;

•

it is consistent with the Company’s policy of facilitating communications of stockholders with the Board of Directors and its various committees, including the Compensation Committee; and

•

because our compensation policies may change year-to-year, it is important to receive feedback on such policies annually.

The Board of Directors intends that the compensation program be responsive to stockholder concerns, and believes that annual advisory votes best facilitates this.

Accordingly, the Board of Directors is asking stockholders to indicate their preferred voting frequency by voting for one, two or three years or abstaining from voting on the resolution below:

“RESOLVED, that the alternative of soliciting advisory stockholder approval of the compensation of the Company’s named executive officers once every one, two or three calendar years that receives the highest number of votes from the holders of shares present in person or represented by proxy and entitled to vote at the annual meeting shall be considered the frequency preferred by the stockholders.”

While the Board of Directors believes that its recommendation is appropriate at this time, the stockholders are not voting to approve or disapprove that recommendation, but are instead asked to indicate their preferences, on an advisory basis, as to whether the non-binding advisory vote on the approval of the Company’s executive officer compensation practices should be held every year, every other year or every three years. The option among those choices that receives the highest number of votes from the holders of shares present in person or represented by proxy and entitled to vote at the annual meeting will be deemed to be the frequency preferred by the stockholders.

The Board of Directors and the Compensation Committee value the opinions of the stockholders in this matter, and the Board of Directors intends to hold say-on-pay votes in the future in accordance with the alternative that receives the most stockholder support, even if that alternative does not receive the support of a majority of the shares present and entitled to vote.

Employment Agreements or Arrangements

Michael R. Bristow, M.D., Ph.D. Dr. Bristow serves as the Company’s President and Chief Executive Officer under an Employment and Retention Agreement dated as of June 4, 2008, as amended. Pursuant to such employment agreement, Dr. Bristow is permitted to continue his academic work for the University of Colorado Health Sciences Center and for the Cardiovascular Institute, so long as it does not interfere with his duties as President and Chief Executive Officer of ARCA.

On February 16, 2017, the Board of Directors approved a 2017 base salary of $304,219 for Dr. Bristow.

There were no changes to Dr. Bristow’s salary for 2018, and the Company did not put in place a bonus plan for the Named Executive Officers for services in 2018 or 2019.

On May 6, 2019, Dr. Bristow agreed to a voluntary 10% salary reduction for the remainder of 2019. As a result of this reduction, the base salary to be paid to Dr. Bristow for 2019 is $273,797. The foregone portion of any salary otherwise owed to Dr. Bristow shall not be paid without the prior approval of the Board of Directors, provided, that such foregone amount shall be included in Dr. Bristow’s base salary for purposes of calculating any severance amounts which may be owed in the future under the terms of his employment agreement with the Company.

If the Company terminates Dr. Bristow’s employment without “cause,” or if Dr. Bristow terminates his employment with “good reason” (as these terms are defined in his employment agreement), the Company has agreed to pay Dr. Bristow a severance payment equivalent to (i) (a) 12 months of his base salary, if such termination occurs on the same day as or within 13 months after a change of control of the Company, or (b) six months of his base salary if such termination does not occur on the same day as or within 13 months after a change of control of the Company, (ii) a pro rata portion of any bonus compensation under any employee bonus plan that has been approved by the Board of Directors payable to him for the fiscal year in which his employment terminated to be paid at the same time that such incentive bonus would have been paid had the termination not occurred, and (iii) reimbursement to cover out-of-pocket costs to continue group health insurance benefits under COBRA for 6 months, whether he elects or is eligible to receive COBRA (provided, that even if he does not elect or is not eligible to receive COBRA, he will receive the equivalent of such out-of-pocket expenses paid by him not to exceed the costs that the benefits would equal under COBRA if he were so eligible). In addition, ARCA may elect in its sole discretion, to pay additional severance equal to up to 6 months of base salary, which additional payment would extend the covenants and obligations under Dr. Bristow’s Employee Intellectual Property, Confidentiality and Non-Compete Agreement for such additional period. The severance payment is conditioned on the execution by Dr. Bristow of a legal release in a form acceptable to the Company. A termination for “cause” includes Dr. Bristow’s willful misconduct, gross negligence, theft, fraud, or other illegal or dishonest conduct, any of which are considered to be materially harmful to the Company; refusal, unwillingness, failure, or inability to perform his material job duties or habitual absenteeism; or violation of fiduciary duty, violation of any duty of loyalty, or material breach of any material term of his employment agreement or his Employee Intellectual Property, Confidentiality and Non-Compete Agreement, or any other agreement, with the Company. “Good reason” includes a relocation by us of Dr. Bristow’s normal work location greater than 30 miles; a decrease in current base salary by more than 15%, with certain exceptions; and the Company’s unilateral decision to significantly and detrimentally reduce Dr. Bristow’s job responsibilities.

Non-Equity Incentive Plan Compensation

In February 2007, the Compensation Committee and the Board of Directors of ARCA established a bonus structure for its entire executive team. The philosophy employed was to create incentives for the executive officers to achieve key corporate goals. The Compensation Committee retained discretion to change the bonus structure and the bonus payment amounts as it considered appropriate.

2017 Cash Bonus Plan

The Board of Directors set corporate goals for 2017 (the “2017 Goals”). Attainment of the 2017 Goals was a prerequisite to the payment of any awards to employees under the Company’s 2017 Cash Bonus Plan, including executive officers.

The amount payable to each employee was set as a target percentage of each employee’s annual salary (the “TBP”),but employees, including executive officers, were eligible to receive more or less than 100% of their TBP, based upon corporate goal achievement, individual performance and the discretion of the Board of Directors.

To receive a cash bonus (if any), each individual employee must have been actively employed by the Company, and in good standing, on December 31, 2017. Employees hired after January 1, 2017, had their cash bonus (if any) prorated based on the percentage of time the employee worked at ARCA in 2017. The 2017 Goals were based on (1) the GENETIC-AF Data and Safety Monitoring Board analysis and enrollment of GENETIC-AF; (2) financing goals; and (3) corporate transaction objectives.

2018 and 2019 Cash Bonuses

The Compensation Committee and Board of Directors did not approve a bonus structure for 2018 or 2019. As such, the Company did not pay any cash bonuses to its Named Executive Officers in 2019 for performance in the 2018 fiscal year and does not anticipate paying any cash bonuses for performance in 2019. Due to the fact that no bonus plans were put in place in 2018 or 2019, the Board of Directors also did not approve any corporate goals for these years.

Other Elements of Executive Compensation Program

The remaining elements of the Company’s executive compensation program, like its broader employee compensation programs, are intended to make the Company’s overall compensation program competitive with those of its peer companies, keeping in mind the constraints imposed by the Company’s reliance on capital markets as a primary source of cash. The remaining elements of the Company’s executive compensation program, (401(k) Plan, Medical, Dental, and Vision Plans, Life and Disability Insurance) are available to all Company employees.

Equity Compensation Plan Information

On September 17, 2013, our stockholders approved the ARCA biopharma, Inc. 2013 Equity Incentive Plan (the “2013 Plan”) at the Company’s 2013 annual meeting of stockholders. The 2013 Plan is the successor to the Amended and Restated ARCA biopharma, Inc. 2004 Equity Incentive Plan. On June 9, 2016, our stockholders approved the Amended and Restated ARCA 2013 Equity Incentive Plan (the “Amended 2013 Plan”). A description of the 2013 Plan and the Amended 2013 Plan is set forth in Note 8 to the Company’s financial statements included in our annual report on Form 10-K for the year ended December 31, 2018, filed with the SEC on February 27, 2019.

Compensation Risks

ARCA believes its approach to goal setting, setting of targets with payouts at multiple levels of performance, and evaluation of performance results assist in mitigating excessive risk-taking that could harm the value or reward poor judgment by its executives. ARCA believes several features of the Company’s programs reflect sound risk management practices. ARCA believes it has allocated compensation among base salary and short and long-term compensation target opportunities in such a way as to not encourage excessive risk-taking. The multi-year vesting of equity awards properly accounts for the time horizon of risk. Furthermore, the Compensation Committee assesses and monitors whether any of ARCA’s compensation policies and programs has the potential to encourage excessive risk-taking on an annual basis.

Certain Relationships and Related Transactions

Certain Transactions With or Involving Related Persons

The following is a summary of transactions since January 1, 2017, to which we have been a party in which the amount involved exceeded the lesser of $120,000 or one percent of the average of our total assets at fiscal yearend for 2017 and 2018, and in which any of our executive officers, directors or holders of more than 5% of our capital stock, or any member of the immediate family of any of the foregoing persons, had or will have a direct or indirect material interest, other than compensation arrangements disclosed above under the heading “Executive Compensation”.

Transactions With the Company’s President and Chief Executive Officer

The Company has entered into unrestricted research grants with the academic research laboratory of Dr. Bristow, the Company’s President and Chief Executive Officer, at the University of Colorado. Funding of any unrestricted research grants is contingent upon the Company’s financial condition, and can be deferred or terminated at the Company’s discretion. Total expense under these arrangements for the six months ended June 30, 2019 and the years ended December 31, 2018 and 2017 was approximately $141,000, $325,000 and $418,000, respectively, of which $111,000 was unpaid and included in Accrued expenses and other liabilities as of December 31, 2018 in the financial statements included in our Annual Report on Form 10-K filed with the SEC on February 27, 2019.

Policies and Procedures for Related Party Transactions

In accordance with its charter, our Audit Committee reviews and approves all related party transactions. This review covers any material 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, including, purchases of goods or services by or from the related party or entities in which the related party has a material interest, indebtedness, guarantees of indebtedness and employment by us of a related party. In evaluating any related party transaction, the Audit Committee considers, among other things, the relative benefits of the transaction to the Company, what, if any, alternatives may be available from persons not affiliated to the Company, if the terms of the transaction have been negotiated on an arm’s length basis and any other matters that the Audit Committee may deem relevant in determining whether such related party transaction is in the best interests of the Company and its stockholders.

Householding of Proxy Materials

The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for the Proxy Materials with respect to two or more stockholders sharing the same address by delivering a single set of the Proxy Materials addressed to those stockholders. This process, which is commonly referred to as “householding,” potentially means extra convenience for stockholders and cost savings for companies.

In connection with the Annual Meeting, a number of brokers with account holders who are ARCA stockholders will be “householding” the Proxy Materials. A single set of the Proxy Materials will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from 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 set of the Proxy Materials, please notify your broker or ARCA. Direct your written request to Secretary, ARCA biopharma, Inc., 11080 CirclePoint Road, Suite 140, Westminster, Colorado, 80020 or contact Investor Relations at 720-940-2100. The Company undertakes to promptly deliver a separate set of the Proxy Materials promptly upon receiving your written request. Stockholders who currently receive multiple copies of the Proxy Materials at their addresses and would like to request “householding” of their communications should contact their brokers.

Other Matters

The Board of Directors knows of no other matters that will be presented for consideration at the Annual Meeting. If any other matters are properly brought before the meeting, it is the intention of the persons named in the accompanying proxy to vote on such matters in accordance with their best judgment.

By Order of the Board of Directors

Christopher Ozeroff

Secretary, Senior Vice President and General Counsel

October 28, 2019

We will provide without charge to each person, including any beneficial owner of our Common Stock to whom a copy of Proxy Materials have been delivered, upon written or oral request, a copy of any or all of the documents referred to above that have been or may be incorporated into these Proxy Materials by reference, including a copy of our Annual Report on Form 10-K as filed with the SEC on February 27, 2019. Requests for copies should be directed to: Corporate Secretary, ARCA biopharma, Inc., 11080 CirclePoint Road, Suite 140, Westminster, Colorado 80020 or contact Investor Relations at 720‑940‑2100.
