Dear Stockholders of Atreca, Inc.:

You are cordially invited to attend the 2021 Annual Meeting of Stockholders (the “Annual Meeting”) of Atreca, Inc., a Delaware corporation (the “Company”). The meeting will be held on Wednesday, June 9, 2021 at 9:00 a.m. Pacific Daylight Time via live webcast on the Internet for the following purposes:

1. to elect three Class II directors nominated by the Company’s Board of Directors to serve until the 2024 Annual Meeting of Stockholders and until their successors are duly elected and qualified;

2. to ratify the selection of OUM & Co. LLP as the independent registered public accounting firm of the Company for its fiscal year ending December 31, 2021; and

3. to conduct any other business properly brought before the Annual Meeting or any adjournment thereof.

These items of business are more fully described in the Proxy Statement (the “Proxy Statement”) accompanying this notice. The record date for the Annual Meeting is April 15, 2021.

Accordingly, you will receive a Notice of Internet Availability of Proxy Materials (the “Notice”) because the Board of Directors (the “Board of Directors” or “Board”) of Atreca, Inc. (the “Company,” “Atreca,” “we,” “us,” and “our”) is soliciting your proxy to vote at the 2021 Annual Meeting of Stockholders (the “Annual Meeting”), including at any adjournments or postponements of 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 Notice.

We intend to mail the Notice on or about April 28, 2021 to all stockholders of record entitled to vote at the Annual Meeting. On the date of mailing the Notice, stockholders will be able to access all of the proxy materials on the website at www.proxyvote.com.

How do I attend the Annual Meeting?

Due to ongoing concerns and restrictions related to the global COVID-19 pandemic, the Annual Meeting will be held on Wednesday, June 9, 2021 at 9:00 a.m. Pacific Daylight Time via live webcast on the Internet at www.virtualshareholdermeeting.com/BCEL2021. Online check-in will begin at approximately 8:45 am Pacific Daylight Time. You can attend the Annual Meeting, vote your shares and submit your questions during the live webcast. You will need your 16-digit control number included in the Notice, the proxy card, or in the instructions that accompany your proxy materials. You cannot attend the Annual Meeting in person. Information on how to vote at the Annual Meeting is discussed below.

If you do not have your 16-digit control number, you will be able to access and listen to the Annual Meeting, but you will not be able to vote your shares or submit questions during the Annual Meeting.

How do I ask questions of management and the Board of Directors at the Annual Meeting?

We will answer questions submitted by stockholders during the Annual Meeting, to the extent relevant to the business of the meeting, as the allotted time permits. Questions may be submitted beginning at 8:45 a.m. Pacific Daylight Time on the day of the Annual Meeting and during the Annual Meeting through www.virtualshareholdermeeting.com/BCEL2021. You will need the 16-digit control number included in your Notice, on your proxy card, or on the instructions that accompanied your proxy materials in order to log into the virtual meeting platform and submit questions.

What if I have technical difficulties during the check-in time or during the live webcast of the Annual Meeting?

If I cannot virtually attend the Annual Meeting, can I vote before the Annual Meeting or listen to the Annual Meeting later?

You may vote your shares electronically before the Annual Meeting by Internet, by proxy or by telephone as described below. You do not need to access the Annual Meeting webcast to vote if you submitted your vote by proxy, by Internet or by telephone before the Annual Meeting. A recording of the Annual Meeting, including the questions answered during the meeting, will be available at www.virtualshareholdermeeting.com/BCEL2021.

Who can vote at the Annual Meeting?

Only stockholders of record at the close of business on April 15, 2021 will be entitled to vote at the Annual Meeting. On this record date, there were 30,175,529 shares of Class A common stock outstanding and entitled to vote.

Stockholder of Record: Shares Registered in Your Name

If, on the record date, your shares were registered directly in your name with our transfer agent, Computshare Trust Company, N.A., then you are a stockholder of record. As a stockholder of record, you may vote online during the Annual Meeting, vote by proxy through the internet or by telephone 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 through the internet or by telephone as instructed below, or by completing a proxy card that you may request or that we may elect to deliver at a later time. Stockholders who attend the Annual Meeting should follow the instructions at www.virtualshareholdermeeting.com/BCEL2021 to vote online during the meeting.

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

If, on the record date, your shares were held, not in your name, but rather in an account at a broker, bank or similar organization, then you are the beneficial owner of shares held in “street name” and the Notice is 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, bank 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 only vote your shares during the Annual Meeting if you request and obtain a valid 16-digit control number from your broker, bank or other agent. Beneficial owners who attend the Annual Meeting should follow the instructions at www.virtualshareholdermeeting.com/BCEL2021 to vote online during the meeting.

What am I voting on?

There are two matters scheduled for a vote:

•

election of three Class II directors nominated by the Board to serve until the 2024 annual meeting of stockholders and until their successors are duly elected and qualified (Proposal 1); and

•

ratification of the selection of OUM & Co. LLP as independent registered public accounting firm of the Company for its fiscal year ending 2021 (Proposal 2).

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

For Proposal 1, you may either vote “For” all the nominees to the Board of Directors or you may “Withhold” your vote for all nominees, or for any nominee you specify. For Proposal 2, 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 electronically 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 via the live webcast, we urge you to vote by proxy to ensure your vote is counted. You may still attend the Annual Meeting via the live webcast and vote electronically even if you have already voted by proxy.

•

To vote electronically at the Annual Meeting, attend the live webcast at www.virtualshareholdermeeting.com/BCEL2021 and use your 16-digit control number included in the Notice, the proxy card, or in the instructions that accompany your proxy materials.

•

To vote using the proxy card, simply complete, sign and date the proxy card that may be delivered 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 1-800-690-6903 using a touch-tone phone and follow the recorded instructions. You will be asked to provide the company number and control number from the Notice. Your telephone vote must be received by 11:59 p.m. Eastern Daylight Time on June 8, 2021 to be counted.

•

To vote through the Internet, go to http://www.proxyvote.com to complete an electronic proxy card. You will be asked to provide the company number and control number from the Notice. Your Internet vote must be received by 11:59 p.m. Eastern Daylight Time on June 8, 2021 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 Atreca, Inc. Simply follow the voting instructions in the Notice to ensure that your vote is counted. Please note, because you are not the stockholder of record, you may only vote your shares during the Annual Meeting if you request and obtain a valid 16-digit control number from your broker, bank or other agent. Beneficial owners who attend the Annual Meeting should follow the instructions at www.virtualshareholdermeeting.com/BCEL2021 to vote during the meeting.

Internet proxy voting allows 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 Internet access, 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 Class A common stock you own as of April 15, 2021.

If I am a stockholder of record and I do not vote, or if I return a proxy card or otherwise vote without giving specific voting instructions, what happens?

If you are a stockholder of record and do not vote by completing your proxy card, by telephone, through the Internet or electronically at the Annual Meeting, your shares will not be voted.

If you return a signed and dated proxy card or otherwise vote without marking voting selections, your shares will be voted, as applicable and “For” the election of all two nominees for director and “For” the ratification of the selection of OUM & Co. LLP as our independent registered public accounting firm. If any other matter is properly presented at the meeting, your proxyholder (one of the individuals named on your proxy card) will vote your shares using his or her best judgment.

If I am a beneficial owner of shares held in street name and I do not provide my broker or bank with voting instructions, what happens?

If you are a beneficial owner of shares held in street name and you do not instruct your broker, bank or other agent how to vote your shares, your broker, bank or other agent may still be able to vote your shares in its discretion. 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 applicable rules, “non-routine” matters may substantially affect the rights or privileges of stockholders, such as mergers, stockholder proposals, elections of directors (even if not contested) and executive compensation, including the advisory stockholder votes on executive compensation and on the frequency of stockholder votes on executive compensation. Proposal 1 is considered to be non-routine. Proposal 2 is considered to be routine.

If you are a beneficial owner of shares held in street name, in order to ensure your shares are voted in the way you would prefer, you must provide voting instructions to your broker, bank or other agent by the deadline provided in the materials you receive from your broker, bank or other agent.

Who is paying for this proxy solicitation?

We will pay for the entire cost of soliciting proxies. In addition to these proxy materials, our directors and employees and Broadridge Financial Services, Inc. (“Broadridge”) may also solicit proxies by telephone, or by other means of communication. Directors and employees will not be paid any additional compensation for soliciting proxies, but Broadridge will be paid its customary fees and out-of-pocket expenses if it solicits 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 the Notices to ensure that all of your shares are voted.

Can I change my vote after submitting my proxy?

Stockholder of Record: Shares Registered in Your Name

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:

•

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 the Company’s General Counsel and Corporate Secretary at 835 Industrial Rd., Suite 400, San Carlos, California 94070; or

•

you may attend the Annual Meeting via the live webcast and vote electronically, but simply attending the Annual Meeting via the live webcast will not, by itself, revoke your proxy.

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

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

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

When are stockholder proposals and director nominations due for the 2022 Annual Meeting of Stockholders?

Any stockholder who meets the requirements of the proxy rules under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), may submit proposals to the Board of Directors to be presented at the 2022 Annual Meeting of Stockholders. Such proposals must comply with the requirements of Rule 14a-8

under the Exchange Act. To be considered for inclusion in next year’s proxy materials, your proposal must be submitted in writing by December 29, 2021, to our General Counsel and Corporate Secretary at 835 Industrial Rd., Suite 400, San Carlos, California 94070; provided, however, that if our 2022 Annual Meeting of Stockholders is held before May 10, 2022 or after July 9, 2022, then the deadline is a reasonable amount of time prior to the date we begin to print and mail our proxy statement for the 2022 Annual Meeting of Stockholders.

Our amended and restated bylaws also provide for separate notice procedures to recommend a person for nomination as a director or to propose business to be considered by stockholders at a meeting, provided that such proposal or nominee would not be included in next year’s proxy materials. Such proposals must comply with the requirements, including without limitation, the separate notice procedures, of our amended and restated bylaws. If you wish to submit such a proposal or nominate a director, written notice must be received by our General Counsel and Corporate Secretary no later than the close of business on March 11, 2022 nor earlier than close of business on February 9, 2022; provided, however, that if our 2022 Annual Meeting of Stockholders is held before May 10, 2022 or after July 9, 2022, then the proposal must be received no earlier than the close of business on the 120th day prior to such Annual Meeting and no later than the close of business on the later of the 90th day prior to such Annual Meeting or the 10th day following the day on which public announcement of the date of such Annual Meeting is first made.

How are votes counted?

Votes will be counted by the inspector of election appointed for the Annual Meeting, who will separately count, for Proposal 1, votes “For,” “Withhold” and broker non-votes; and, with respect to Proposal 2 and any other proposals, votes “For” and “Against,” abstentions and, if applicable, broker non-votes. Abstentions will be counted towards the vote total for each of Proposals 1 and 2, and will have the same effect as “Against” votes. Broker non-votes have no effect and will not be counted towards the vote total for any proposal.

What are “broker non-votes”?

As discussed above, when a beneficial owner of shares held in street name does not give voting instructions to his or her broker, bank or other securities intermediary holding his or her shares as to how to vote on matters deemed to be “non-routine”, the broker, bank or other such agent cannot vote the shares. These un-voted shares are counted as “broker non-votes.”

As a reminder, if you a beneficial owner of shares held in street name, in order to ensure your shares are voted in the way you would prefer, you must provide voting instructions to your broker, bank or other agent by the deadline provided in the materials you receive from your broker, bank or other agent.

How many votes are needed to approve each proposal?

For Proposal 1, election of directors, the three nominees receiving the most “For” votes from the holders of shares present or represented by proxy and entitled to vote on the election of directors will be elected. Only votes “For” will affect the outcome. Broker non-votes and “Withhold” votes will have no effect on the outcome of Proposal 1.

For Proposal 2, ratification of the selection of OUM & Co. LLP as the Company’s independent registered public accounting firm for fiscal year 2021, the proposal must receive “For” votes from the holders of a majority of shares present or represented by proxy and entitled to vote on the matter. If you “Abstain” from voting, it will have the same effect as an “Against” vote. As described above, because Proposal No. 2 is considered to be a “routine” matter under applicable rules, your broker, bank or other nominee may generally vote in their discretion on Proposal 2 and therefore we do not expect any broker non-votes on Proposal 2.

What is the quorum requirement?

A quorum of stockholders is necessary to hold a valid Annual Meeting. A quorum will be present if stockholders holding at least a majority of the outstanding shares entitled to vote are present at the Annual Meeting via the live webcast or represented by proxy. On the record date, there were 30,175,529 shares

outstanding and entitled to vote. Thus, the holders of 15,087,765 shares must be present at the Annual Meeting via the live webcast or represented by proxy 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 electronically at the Annual Meeting. Abstentions and broker non-votes will be counted towards the quorum requirement. If there is no quorum, the holders of a majority of shares present at the Annual Meeting via the live webcast or represented by proxy may adjourn the Annual 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 amended report on Form 8-K to publish the final results.

Proposal 1

Election of Directors

Classified Board

Our Board of Directors is divided into three classes: Class I; Class II; and Class III. Each class consists, as nearly as possible, of one-third of the total number of directors, and each class has a three-year term. Vacancies on the Board may be filled only by persons elected by a majority of the remaining directors. A director elected by the Board 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 Board of Directors presently has eight members. In 2021, the term of the three directors in Class II expires. Each of the nominees listed below is currently a director of the Company who was previously elected or appointed to the Board. If elected at the Annual Meeting, each of these nominees would serve until the Company’s 2024 Annual Meeting of Stockholders and until his or her successor has been duly elected and qualified, or, if sooner, until the director’s death, resignation or removal.

Directors are elected by a plurality of the votes of the holders of shares present live via webcast or represented by proxy and entitled to vote on the election of directors. Accordingly, the two nominees receiving the highest number of affirmative votes will be elected.

The nominees and the directors who are currently serving on the Board, their ages and length of board service as of May 1, 2021, are provided in the table below. Below the table is a brief biography of each nominee and each director whose term will continue after the Annual Meeting.

Information Regarding the Board of Directors and Corporate Governance

Independence of The Board of Directors

As required under the 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 has undertaken a review of its composition, the composition of its committees and the independence of each director. In addition, our Board consults with the Company’s counsel to ensure that the Board’s 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 Nasdaq and applicable SEC rules, as in effect from time to time.

Consistent with these considerations, and after review of the information requested from and provided by each director concerning his or her background, employment and affiliations, including family relationships, our Board has determined that the following five directors, representing a majority of our directors, are independent directors, do not have any relationships that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director, and that each of these directors is otherwise “independent” as that term is defined under applicable Nasdaq listing standards: Messrs. Atwood and Berger, Ms. Ball, and Drs. Lacey and Rolfe. In making this determination, the Board found that none of these directors or, in the case of Mr. Atwood, a nominee for director, had a material or other disqualifying relationship with the Company.

Board Leadership Structure

Brian Atwood is the current Chairman of our Board of Directors and John A. Orwin is our current Chief Executive Officer, hence the roles of Chairman of our Board of Directors and Chief Executive Officer are separated. We believe that separating these positions allows our Chief Executive Officer to focus on our day-to-day business, while allowing the Chairman of our Board to lead the Board of Directors in its fundamental role of providing advice to and independent oversight of management. Our Board of Directors recognizes the time, effort and energy that the Chief Executive Officer is required to devote to his position, as well as the commitment required to serve as our Chairman of our Board of Directors, particularly as the Board of Directors’ oversight responsibilities continue to grow. While our amended and restated bylaws and corporate governance guidelines do not require that our Chairman and Chief Executive Officer positions be separate, our Board of Directors believes that having separate positions is the appropriate leadership structure for us at this time and demonstrates our commitment to good corporate governance.

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 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 various Board standing committees that address risks inherent in their respective areas of oversight. In particular, our Board is responsible for monitoring and assessing strategic risk exposure, including a determination of the nature and level of risk appropriate for the Company. Our Audit Committee (“Audit Committee”) has the responsibility to consider and discuss our major financial risk exposures and the steps our 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 legal matters and compliance with legal and regulatory requirements regarding the Company’s financial statements and accounting or other policies. Our Nominating and Corporate Governance Committee (“Nominating and Corporate Governance Committee”) monitors the effectiveness of our corporate governance guidelines, including whether they are successful in preventing illegal or improper liability-creating conduct. Our Compensation Committee (“Compensation Committee”) assesses and monitors whether any of our compensation policies and programs have the potential to encourage excessive risk-taking. It is the responsibility of the Board committee Chairs to report findings regarding material risk exposures to the Board as quickly as possible. In addition, the Board meets with certain members of our executive team, including the heads of our business, compliance and regulatory functions, who discuss the risks and exposures involved in their respective areas of responsibility as well as any developments that could impact our risk profile or other aspects of our business.

Meetings of The Board of Directors

The Board of Directors held 12 meetings during 2020. All directors attended 75% or more of the aggregate number of meetings of the Board and of the Board committees on which he or she served during the portion of 2020 that each such director served on the Board or such committees. Although the Company has no formal policy regarding attendance by members of our Board at the company’s annual meeting of stockholders, all of the members then serving attended the 2020 Annual Meeting of Stockholders held on June 10, 2020.

Information Regarding Committees of the Board of Directors

The Board has an Audit Committee, a Compensation Committee and a Nominating and Corporate Governance Committee. The Board also has a Research and Development Committee, which is an advisory committee.

The following table provides membership and 2020 meeting information for each of the Board committees:

Committee Chair

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, except as specifically described below, each member of each committee meets the applicable Nasdaq rules and regulations regarding “independence” and each member is free of any relationship that would impair his or her individual exercise of independent judgment with regard to the Company.

Stockholders and other interested parties who wish to communicate with the non-management or independent members of our Board may do so by letters addressed to the attention of our General Counsel and Corporate Secretary.

Audit Committee

The Audit Committee is composed of three directors: Messrs. Atwood and Berger and Ms. Ball. Mr. Berger is the Chair of the Audit Committee.

The Audit Committee was established by the Board in accordance with Section 3(a)(58)(A) of the Exchange Act, for the primary purpose of discharging the responsibilities of our Board of Directors with respect to our corporate accounting and financial reporting processes, systems of internal control and financial statement audits, and to oversee our independent registered public accounting firm. Specific responsibilities of our Audit Committee include:

•

helping our Board oversee our corporate accounting and financial reporting processes;

•

managing the selection, engagement, qualifications, independence and performance of a qualified firm to serve as the independent registered public accounting firm to audit our financial statements;

•

discussing the scope and results of the audit with the independent registered public accounting firm, and reviewing, with management and the independent accountants, our interim and year-end operating results;

•

developing procedures for employees to submit concerns anonymously about questionable accounting or audit matters;

•

reviewing related person transactions;

•

establishing insurance coverage for the Company’s officers and directors;

•

overseeing the preparation of the Audit Committee report required in the Company’s annual proxy statement, reviewing with management the Company’s financial statements to be included the Company’s quarterly reports to be filed with the Securities and Exchange Commission (“SEC”), and reviewing with management the “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” disclosures in the Company’s periodic reports filed with the SEC;

•

obtaining and reviewing a report by the independent registered public accounting firm at least annually that describes our internal quality control procedures, any material issues with such procedures and any steps taken to deal with such issues when required by applicable law; and

•

approving or, as permitted, pre-approving, audit and permissible non-audit services to be performed by the independent registered public accounting firm.

The Board has adopted a written Audit Committee charter that is available on the “Investors & Media” section of our website at https://ir.atreca.com/corporate-governance/documents-and-charters.

The Board of Directors reviews the Nasdaq listing standards definition of independence for Audit Committee members on an annual basis and has determined that each Audit Committee member satisfies the independence requirements under the listing standards of Nasdaq and Rule 10A-3(b)(1) of the Exchange Act and qualifies as an “audit committee financial expert” within the meaning of SEC regulations. In arriving at these determinations, our Board of Directors has examined each Audit Committee member’s scope of experience and the nature of their employment in the corporate finance sector.

Report of the Audit Committee of the Board of Directors

The Audit Committee reviewed and discussed the audited financial statements for the fiscal year ended December 31, 2020 with management of the Company. The Audit Committee discussed with the independent registered public accounting firm the matters required to be discussed by applicable requirements of the Public Company Accounting Oversight Board (“PCAOB”) and the SEC. The Audit Committee 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 accountant’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 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, 2020.

Members of the Audit Committee

Mr. Franklin Berger, Chair
Mr. Brian Atwood
Ms. Kristine M. Ball

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 or the Exchange Act, whether made before or after the date hereof and irrespective of any general incorporation language in any such filing.

Compensation Committee

The Compensation Committee is composed of three directors: Mr. Atwood, Drs. Lacey and Rolfe. Mr. Atwood is the Chair of the Compensation Committee.

The primary purpose of our Compensation Committee is to discharge the responsibilities of our Board of Directors in overseeing our compensation policies, plans and programs and to review and determine the compensation to be paid to our executive officers, directors and other senior management, as appropriate. Specific responsibilities of our Compensation Committee include:

•

reviewing and recommending to the Board, or reviewing and approving, the compensation of our Chief Executive Officer, other executive officers and senior management;

•

reviewing and recommending to our Board the compensation paid to our directors;

•

selecting compensation consultants, independent legal counsel and other advisors;

•

administering our equity incentive plans and other benefit programs;

•

reviewing, adopting, amending and terminating incentive compensation and equity plans, severance agreements, profit sharing plans, bonus plans, change-of-control protections and any other compensatory arrangements for our executive officers and other senior management; and

•

reviewing and establishing general policies relating to compensation and benefits of our employees, including our overall compensation philosophy.

In addition, after the Company ceases to be an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012, the Compensation Committee will review with management the Company’s Compensation Discussion and Analysis and consider whether to recommend that it be included in proxy statements and other filings.

The Board has adopted a written Compensation Committee charter that is available on the “Investors & Media” section of our website at https://ir.atreca.com/corporate-governance/documents-and-charters.

The Board of Directors reviews the Nasdaq listing standards definition of independence for Compensation Committee members on an annual basis and has determined that each Compensation Committee member satisfies the independence requirements under the listing standards of Nasdaq and Rule 10C-1 under the Exchange Act, and qualifies as a “non-employee director” within the meaning of Rule 16b-3 under the Exchange Act.

Compensation Committee Processes and Procedures

Typically, the Compensation Committee meets quarterly and with greater frequency if necessary. The agenda for each meeting is usually developed by the Chair of the Compensation Committee, in consultation with our Chief Executive Officer. 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. The charter of the Compensation Committee grants the Compensation Committee full access to all books, records, facilities and personnel of the Company. In addition, under the charter, the Compensation Committee has the authority to obtain, at the expense of the Company, advice and assistance from compensation consultants and internal and external legal, accounting or other advisors and other external resources that the Compensation Committee considers necessary or appropriate in the performance of its duties. The Compensation Committee has direct responsibility for the oversight of the work of any consultants or advisers engaged for the purpose of advising the Committee. In particular, the Compensation Committee has the sole authority to retain, in its sole discretion, 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. Under the charter, the Compensation Committee may select, or receive advice from, a compensation consultant, legal counsel or other adviser to the Compensation Committee, other than in-house legal counsel and certain other types of advisers, only after taking into consideration six factors, prescribed by the SEC and Nasdaq, that bear upon the adviser’s independence; however, there is no requirement that any adviser be independent.

During 2020, after taking into consideration the six factors prescribed by the SEC and Nasdaq described above, the Compensation Committee engaged Aon plc/Radford as compensation consultants. The Compensation Committee requested that Aon plc/Radford:

•

evaluate the efficacy of the Company’s existing compensation strategy and practices in supporting and reinforcing the Company’s long-term strategic goals; and

•

assist in refining the Company’s compensation strategy and in developing and implementing an executive compensation program to execute that strategy.

As part of its engagement, Aon plc/Radford was requested by the Compensation Committee to develop a comparative group of companies and to perform analyses of competitive performance and compensation levels for that group. At the request of the Compensation Committee, Aon plc/Radford also conducted individual interviews with members of the Compensation Committee and senior management to learn more about the Company’s business operations and strategy, key performance metrics and strategic goals, as well as the labor markets in which the Company competes. Aon plc/Radford ultimately developed recommendations that were presented to the Compensation Committee for its consideration. Following an active dialogue with Aon plc/Radford, the Compensation Committee approved the recommendations.

Generally, the Compensation Committee’s process comprises two related elements: the determination of compensation levels and the establishment of annual performance objectives. Typically in the first quarter of each year, the Compensation Committee reviews and approves, or recommends to the Board, the compensation, including annual salary, bonus and equity awards, for the Chief Executive Officer, the other executive officers and senior management, and the Company’s annual corporate performance objectives. For executives other than the Chief Executive Officer, the Compensation Committee solicits and considers evaluations and recommendations submitted to the Committee by the Chief Executive Officer. In the case of the Chief Executive Officer, the evaluation of his performance is conducted by the Compensation Committee. For all executives and directors 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 and recommendations of the Compensation Committee’s compensation consultant, including analyses of executive and director compensation paid at other companies identified by the consultant. In addition, 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.

Nominating and Corporate Governance Committee

The Nominating and Corporate Governance Committee is composed of three directors: Dr. Lacey, Ms. Ball and Mr. Berger. Dr. Lacey is the Chair of the Nominating and Corporate Governance Committee.

Specific responsibilities of our Nominating and Corporate Governance Committee include:

•

identifying and evaluating candidates, including the nomination of incumbent directors for reelection and nominees recommended by stockholders, to serve on our Board;

•

considering and making recommendations to our board of directors regarding the composition and chairmanship of the committees of our Board;

•

instituting plans or programs for the continuing education of our board of directors and orientation of new directors;

•

developing and making recommendations to our board of directors regarding corporate governance guidelines and matters; and

•

overseeing periodic evaluations of the board of directors’ performance, including committees of the Board.

The Board has adopted a written Nominating and Corporate Governance Committee charter that is available on the “Investors & Media” section of our website at https://ir.atreca.com/corporate-governance/documents-and-charters.

The Board of Directors reviews the Nasdaq listing standards definition of independence for Board members on an annual basis and has determined that each Nominating and Corporate Governance Committee member satisfies the independence requirements under the listing standards of Nasdaq and applicable SEC rules.

The Nominating and Corporate Governance Committee believes that candidates for director should have certain minimum qualifications, including the ability to read and understand basic financial statements, being over 21 years of age and having the highest personal integrity and ethics. The Nominating and Corporate Governance Committee also intends to consider such factors as possessing relevant expertise upon which to be able to offer advice and guidance to management, having sufficient time to devote to the affairs of the Company, demonstrated excellence in his or her field, having the ability to exercise sound business judgment and having the commitment to rigorously represent the long-term interests of the Company’s stockholders. 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, 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 (including gender, racial and ethnic diversity), age, skills and such other factors as it deems appropriate, given the current needs of the Board and the Company, to maintain a balance of knowledge, experience and capability.

The Nominating and Corporate Governance Committee identifies and considers experience, qualities, skills and other director attributes that would enhance the composition of the Board. In the case of incumbent directors whose terms of office are set to expire, the Committee reviews these directors’ overall service to the Company during their terms, including the number of meetings attended, level of participation, quality of performance and any other relationships and transactions that might impair the directors’ independence. The Committee also considers the results of the Board’s self-evaluation, conducted annually on a group and individual basis and every three years, conducted with an outside consultant. In the case of new director candidates, the Nominating and Corporate Governance Committee also determines whether the nominee is independent for Nasdaq 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 then uses its network of contacts to compile a list of potential candidates, but may also engage, if it deems appropriate, a professional search firm. 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. The Nominating and Corporate Governance Committee meets to discuss and consider the candidates’ qualifications and then selects a nominee for recommendation to the Board by majority vote.

The Nominating and Corporate Governance Committee will consider director candidates recommended by stockholders. The Nominating and Corporate Governance Committee does not intend to alter the manner in which it evaluates candidates, including the minimum criteria set forth above, based on whether or not the candidate was recommended by a stockholder. Stockholders who wish to recommend individuals for consideration by the Nominating and Corporate Governance Committee to become nominees for election to the Board may do so by delivering a written recommendation to the Nominating and Corporate Governance Committee at the following address: 835 Industrial Rd., Suite 400, San Carlos, California 94070 in accordance with the requirements set forth in our amended and restated bylaws. Submissions 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 nominating stockholder is a beneficial or record holder of the Company’s stock and has been a holder for at least one year. 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.

Research and Development Committee (Advisory)

The Research and Development Committee is composed of three directors: Drs. Lacey, Robinson and Rolfe. Dr. Robinson is the Chair of the Research and Development Committee. The Research and Development Committee provides advice and support to the Company related to its technologies and its research and development activities, strategy and goals and, at the request of the Board from time to time, reviews and advises the Board on such matters.

The Board has adopted a written Research and Development Committee charter that is available on the “Corporate Governance” section of our website at https://ir.atreca.com/corporate-governance/documents-and-charters.

Stockholder Communications with the Board of Directors

Historically, we have not provided a formal process related to stockholder communications with the Board. Nevertheless, every effort has been made to ensure that the views of stockholders are heard by the Board or individual directors, as applicable, and that appropriate responses are provided to stockholders in a timely manner. We believe our responsiveness to stockholder communications to the Board has been excellent. Nevertheless, during the upcoming year, the Nominating and Corporate Governance Committee will consider the adoption of a formal process for stockholder communications with the Board and, if adopted, publish it promptly and post it to our website.

Code of Business Conduct and Ethics

We have adopted a written Code of Business Conduct and Ethics, which applies to our directors, officers and employees, including our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions. Our Code of Business Conduct and Ethics is available under the “Corporate Governance” section of our website at https://ir.atreca.com/corporate-governance/documents-and-charters. We plan to post on our website at the address described above any future amendments to or waivers of our Codes of Business Conduct and Ethics.

Anti-Hedging Prohibition

Atreca employees, directors and consultants are prohibited from engaging in any hedging transactions of Atreca securities, including through the use of financial instruments such as prepaid variable forwards, equity swaps, collars and exchange funds, as required by our insider trading policy.

We have adopted a Non-Employee Director Compensation Policy pursuant to which our non-employee directors are eligible to receive compensation for service on our Board of Directors and committees of our Board of Directors. In January 2020, the Board amended the Non-Employee Director Compensation Policy to add the annual cash compensation payable to members and the Chair of the Research and Development Committee.

Under the Non-Employee Director Compensation Policy, non-employee directors are paid annual cash compensation of $35,000. In addition, non-employee directors are paid $7,500 annually for serving on the Audit Committee ($15,000 annually for the Chair), $5,000 annually for serving on the Compensation Committee ($10,000 annually for the Chair), $5,000 annually for serving on the Research and Development Committee ($10,000 annually for the Chair), and $4,000 annually for serving on the Nominating and Governance Committee ($8,000 annually for the Chair).

Non-employee directors will be reimbursed for their reasonable out-of-pocket expenses to cover attendance at and participation in meetings of our board of directors.

Newly appointed or newly elected directors will be granted an option to purchase 24,000 shares of our Class A common stock. The initial option grant will vest in equal annual installments over three years from the date of grant, subject to the non-employee director’s continuous service on each applicable vesting date. At the close of business on the date of each annual meeting of stockholders, each individual who is then a non-employee director will be granted an option to purchase 12,000 shares of our Class A common stock. The annual option grant will vest upon the earlier of the one-year anniversary of the date of grant or the day prior to our next annual meeting of stockholders occurring after the grant date, subject to the non-employee director’s continuous service on each applicable vesting date. All options granted under our director compensation policy will be granted with an exercise price equal to the fair market value of our Class A common stock on the grant date. The vesting of all options will cease upon a non-employee director’s cessation of service, unless otherwise determined pursuant to our 2019 Equity Incentive Plan or by agreement. All unvested options will vest in full immediately prior to a change in control (as defined in our 2019 Equity Incentive Plan), subject to the non-employee director’s continuous service as of immediately prior to the closing of such change in control.

Proposal 2
Ratification of Selection of Independent Registered Public Accounting Firm

The Audit Committee has selected OUM & Co. LLP (“OUM”) as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2021 and has further directed that management submit the selection of its independent registered public accounting firm for ratification by the stockholders at the Annual Meeting. OUM has audited the Company’s financial statements since November 13, 2017. Representatives of OUM are expected to attend the Annual Meeting via the live webcast. 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 amended and restated bylaws nor other governing documents or law require stockholder ratification of the selection of OUM as the Company’s independent registered public accounting firm. However, the Board is submitting the selection of OUM 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 or not to retain that firm. Even if the selection is ratified, the Board in its discretion may direct the appointment of different independent auditors 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 or represented by proxy and entitled to vote on the matter at the Annual Meeting will be required to ratify the selection of OUM.

The Board Of Directors Recommends A Vote In Favor Of Proposal 2.

Principal Accountant Fees and Services

The following table represents aggregate fees billed to the Company for the fiscal years ended December 31, 2020 and December 31, 2019, by OUM & Co. LLP, the Company’s principal accountant.

Audit Fees consist of professional services rendered in connection with the audit of our annual consolidated financial statements, including services that are normally provided by the independent registered public accounting firm in connection with statutory and regulatory filings or engagements for 2020. Fees for fiscal 2020 also consisted of professional services rendered in connection with our Registration Statement on Form S-3 related to the public offering of our common stock completed in July 2020. Fees for fiscal 2019 also consisted of professional services rendered in connection with our Registration Statement on Form S-1 related to the initial public offering of our common stock completed in June 2019.

Pre Approval Policies and Procedures.

The Audit Committee has adopted a policy and procedures for the pre-approval of audit and non-audit services rendered by the Company’s independent registered public accounting firm, OUM & Co. LLP. The policy generally pre-approves specified services in the defined categories of audit services, audit-related services and tax services up to specified amounts. Pre-approval may also be given as part of the Audit Committee’s approval of the scope of the engagement of the independent auditor or on an individual, explicit, case-by-case

basis before the independent auditor is engaged to provide each service. The pre-approval of services may be delegated to one or more of the Audit Committee’s members, but the decision must be reported to the full Audit Committee at its next scheduled meeting.

The Audit Committee has determined that the rendering of services other than audit services by OUM & Co. LLP is compatible with maintaining the principal accountant’s independence.

Agreements with our Named Executive Officers & Potential Payments Upon Termination or Change in Control

Below are descriptions of our employment agreements and offer letter agreements with our named executive officers. The agreements generally provide for at-will employment and set forth the named executive officer’s initial base salary, eligibility for employee benefits and severance benefits upon a qualifying termination of employment. Furthermore, each of our named executive officers has executed a form of our standard proprietary information and inventions assignment agreement. The key terms of the employment agreements with our named executive officers, including potential payments upon termination or change of control, are described below. Following the completion of our initial public offering, our Board of Directors adopted certain changes in compensation for certain of our named executive officers to better align their

compensation with that of executives at a peer group of life-science public companies identified by the Compensation Committee (“Peer Benchmarking Adoption”).

John A. Orwin

In November 2020, we entered into an amended and restated executive employment agreement with John A. Orwin (the “Orwin Employment Agreement”), which provides for his at-will employment as our President and Chief Executive Officer, with no specific term. The Orwin Employment Agreement provides for an annual base salary of $566,500 and an annual discretionary bonus of up to 55% of his base salary, the amount of which will be decided by our Board of Directors or the Compensation Committee, in its sole discretion, based upon our and Mr. Orwin’s achievement of objectives and milestones determined on an annual basis by our Board of Directors or the Compensation Committee. Mr. Orwin has also executed our standard form of employee confidential information and inventions assignment agreement, whereby he agrees to maintain confidentiality regarding any confidential information regarding the company and assigns to the Company all intellectual property pertaining to our company.

The Orwin Employment Agreement provides for payments to be made to Mr. Orwin upon certain qualifying terminations of his employment, including in connection with a Change of Control of the Company (as such term is defined in the Orwin Employment Agreement and summarized below). Pursuant to the Orwin Employment Agreement, if Mr. Orwin (i) is terminated without Cause (as such term is defined in the Orwin Employment Agreement and summarized below) and other than as a result of death or disability or (ii) resigns for Good Reason (as such term is defined in the Orwin Employment Agreement and summarized below), in either case prior to the 30 day period prior to the closing of a Change of Control or more than 12 months following the closing of a Change in Control, then, provided that Mr. Orwin signs, and does not subsequently revoke, a separation agreement and release of claims in favor of the Company, Mr. Orwin will receive the following (which amounts reflect the Peer Benchmarking Adoption): (i) a severance payment equal to twelve months of his base salary and (ii) payment by us of an amount equal to twelve months of premiums under the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”) for Mr. Orwin (including eligible dependents, if applicable), to be paid in a lump sum within 60 days following his termination of employment, provided the Separation Agreement (as such term is defined in the Orwin Employment Agreement) has become effective.

If Mr. Orwin (i) is terminated without Cause (as such term is defined in the Orwin Employment Agreement and summarized below) and other than as a result of death or disability or (ii) resigns for Good Reason (as such term is defined in the Orwin Employment Agreement and summarized below), in either case within the 30 day period prior to the closing of a Change of Control or within the twelve month period following the closing of a Change in Control, then, provided that Mr. Orwin signs, and does not subsequently revoke, a separation agreement and release of claims in favor of the Company, Mr. Orwin will receive the following (which amounts reflect the Peer Benchmarking Adoption): (i) a severance payment equal to eighteen months of his base salary, (ii) eighteen months (1.5x) of his target annual cash bonus, (iii) a lump sum payment by us equal to eighteen months of COBRA premiums for Mr. Orwin (including eligible dependents, if applicable), to be paid in a lump sum within 60 days following his termination of employment, provided the Separation Agreement (as such term is defined in the Orwin Employment Agreement) has become effective, and (iv) accelerated vesting (a) of all time-based vesting Equity Awards (as such term is defined in the Orwin Employment Agreement) and (b) performance-based vesting Equity Awards as if all performance goals were achieved at the 100% level of performance and such number of shares subject to such Equity Awards shall be deemed immediately vested, and exercisable, as of Mr. Orwin’s last day of employment.

If Mr. Orwin’s employment with the Company terminates as a result of death or disability, then the Company shall accelerate the vesting of 50% of the outstanding unvested equity awards held by Mr. Orwin on his last day of employment.

For the purposes of the Orwin Employment Agreement, “Cause” means Mr. Orwin’s (a) commission of any felony or crime involving dishonesty; (b) participation in any fraud against the Company; (c) material breach of his duties to the Company; (d) intentional damage to any property of our company; (e) misconduct, or other violation of our policy that causes harm; (f) breach of any written agreement with our company; and (g) conduct which in the good faith and reasonable determination of our Board of Directors demonstrates gross unfitness to serve.

For the purposes of the Orwin Employment Agreement, “Change of Control” means (i) any consolidation or merger by us with or into any other entity other than any consolidation or merger in which the shares of our capital stock immediately prior the consolidation or merger continue to represent a majority of the voting power of the surviving entity immediately after the consolidation or merger or (ii) any transaction or series of related transactions to which we are a party and in which more than 50% of our voting power is transferred, provided that a Change of Control does not include any transaction or series of transactions principally for bona fide equity financing purposes where we receive cash or in which any of our indebtedness is cancelled.

Norman Michael Greenberg, Ph.D

In November 2020, we entered into an amended and restated executive employment agreement with Norman Michael Greenberg, Ph.D (the “Greenberg Employment Agreement”), which provides for his at-will employment as our Senior Vice President and Chief Scientific Officer, with no specific term. The Greenberg Employment Agreement provides for an annual base salary of $425,390 and an annual discretionary bonus of up to 40% of his base salary, the amount of which will be decided by our Board of Directors, the Compensation Committee, or our Chief Executive Officer, as applicable, in its sole discretion, based upon our and Dr. Greenberg’s achievement of objectives and milestones determined on an annual basis by our Board of Directors, the Compensation Committee, or our Chief Executive Officer, as applicable. The Greenberg Employment Agreement also provides Dr. Greenberg a $6,270 per month housing and travel stipend. Mr. Greenberg has also executed our standard form of employee confidential information and inventions assignment agreement, whereby he agrees to maintain confidentiality regarding any confidential information regarding the company and assigns to the Company all intellectual property pertaining to our company.

signs, and does not subsequently revoke, a separation agreement and release of claims in favor of the Company, Dr. Greenberg will receive the following (which amounts reflect the Peer Benchmarking Adoption): (i) a severance payment equal to nine months of his base salary and (ii) payment by us of an amount equal to nine months of premiums under COBRA for Dr. Greenberg (including eligible dependents, if applicable), to be paid in a lump sum within 60 days following his termination of employment, provided the Separation Agreement (as such term is defined in the Greenberg Employment Agreement) has become effective.

If Dr. Greenberg (i) is terminated without Cause (as such term is defined in the Greenberg Employment Agreement and summarized below) and other than as a result of death or disability or (ii) resigns for Good Reason (as such term is defined in the Greenberg Employment Agreement and summarized below), in either case within the 30 day period prior to the closing of a Change of Control or within the twelve month period following the closing of a Change in Control, then, provided that Dr. Greenberg signs, and does not subsequently revoke, a separation agreement and release of claims in favor of the Company, Dr. Greenberg will receive the following (which amounts reflect the Peer Benchmarking Adoption): (i) a severance payment equal to twelve months of his base salary, (ii) twelve months (1x) of his target annual cash bonus, (iii) a lump sum payment by the Company equal to twelve months of COBRA premiums for Dr. Greenberg (including eligible dependents, if applicable), to be paid in a lump sum within 60 days following his termination of employment, provided the Separation Agreement (as such term is defined in the Greenberg Employment Agreement) has become effective, and (iv) accelerated vesting of all time-based vesting Equity Awards (as such term is defined in the Greenberg Employment Agreement) and performance-based vesting Equity Awards as if all performance goals were achieved at the 100% level of performance and such number of shares subject to such Equity Awards shall be deemed immediately vested, and exercisable, as of Dr. Greenberg’s last day of employment.

If Mr. Dr. Greenberg’s employment with the Company terminates as a result of death or disability, then as of the termination date, (i) Dr. Greenberg’s then-unvested equity awards shall cease to vest, (ii) all unearned compensation payments to Dr. Greenberg will terminate immediately and (iii) Dr. Greenberg will not be entitled to any severance benefits, including any cash severance, payment by us of his COBRA premiums or special cash payments.

For the purposes of the Greenberg Employment Agreement, “Cause” means Dr. Greenberg’s (a) commission of any felony or crime involving dishonesty; (b) participation in any fraud or embezzlement against the Company; (c) material breach of his duties to the Company; (d) persistent unsatisfactory performance of job duties after written notice from our Chief Executive Officer and a reasonable opportunity to cure (if curable); (e) intentional damage to any property of the Company; (f) misconduct or other violation of our policy that has caused, or is reasonably expected to result in, harm to the Company; (g) breach of any written agreement with our Company; and (h) conduct which in the good faith and reasonable determination of our Chief Executive Officer demonstrates gross unfitness to serve.

The Greenberg Employment Agreement defines “Change of Control” in a manner similar to the Orwin Employment Agreement (as described above).

In the event that the severance and other benefits payable to Mr. Orwin, Mr. Cross or Dr. Greenberg constitute “parachute payments” under Section 280G of the U.S. tax code and would be subject to the applicable excise tax under Section 4999 of the Code, such severance and other benefits will be either (A) delivered in full or (B) delivered to such lesser extent which would result in no portion of such severance and other benefits being subject to the excise tax, whichever results in the receipt on an after-tax basis of the greatest amount of benefits.

Dr. Greenberg’s Transition Separation and Consulting Agreement

In March 2021, Dr. Greenberg resigned from his position as Senior Vice President and Chief Scientific Officer of the Company to pursue a new business opportunity. Dr. Greenberg’s resignation was not the result of any disagreement with the Company on any matter relating to the Company’s operations, policies, or practices. We entered into a Transition Separation and Consulting Agreement (the “Separation and Consulting Agreement”) with Dr. Greenberg, effective March 31, 2021, under which Dr. Greenberg agreed to a customary release of claims against the Company in exchange for severance payments and other terms, including, as follows: (i) a lump sum payment of $328,884, equal to nine months of his base salary; (ii) a consulting arrangement whereby he may provide certain consulting services to the Company for an hourly consulting fee of $450, through December 31, 2021, unless earlier terminated (the “Consulting Period”); (iii) continued vesting through the Consulting Period of each outstanding and unvested stock option, unit or other award (each, an “Equity Award”) held as of March 31, 2021; (iv) an extension of the post-termination exercise period such that all outstanding Equity Awards that are stock options, to the extent vested as of the last day of the Consulting Period, would continue to be exercisable and not expire until the date that is twelve months following the last day of the Consulting Period; (v) a lump sum payment of $8,634, equal to nine months of the cost of COBRA medical insurance premiums. Effective March 31, 2021, the Greenberg Employment Agreement was no longer in effect and was superseded by the Separation and Consulting Agreement; (vi) a confidentiality covenant; (vii) a mutual non-disparagement covenant; and (viii) a cooperation covenant.

Non-Equity Incentive Plan Compensation

In addition to base salaries, our named executive officers are eligible to receive performance-based cash bonuses, which are designed to provide appropriate incentives to our executives to achieve defined performance goals and to reward our executives for individual achievement towards these goals. The performance-based cash bonus each executive officer is eligible to receive is generally based on the extent to which we achieve the corporate goals and the extent to which our executives achieve their individual goals that our Board or Compensation Committee establishes at the beginning of each year and is paid annually.

401(k) Plan

We maintain a 401(k) plan that provides eligible U.S. employees with an opportunity to save for retirement on a tax advantaged basis. Eligible employees are able to defer eligible compensation up to certain limits of the Internal Revenue Code of 1986, as amended (the “Code”), which are updated annually. Under our current matching policy approved by the Compensation Committee of the Board in October 2020, we match in cash 100% of an employee’s 401(k) contributions, subject to an annual cap of $5,000 per employee. The 401(k) plan is intended to be qualified under Section 401(a) of the Code, with the related trust intended to be tax exempt under Section 501(a) of the Code. As a tax-qualified retirement plan, contributions to the 401(k) plan are deductible by us when made, and contributions and earnings on those amounts are not generally taxable to the employees until withdrawn or distributed from the 401(k) plan.

Rule 10b5-1 Sales Plans

From time to time, our executive officers and directors may be parties to individual Rule 10b5-1 trading plans. Under a Rule 10b5-1 plan, a broker sells the officer’s or director’s shares of our Class A common stock from time to time in accordance with the parameters established by the officer or director when entering into the plan without any further action, direction, or involvement by the officer or director. Our executive officers and directors may only enter into a Rule 10b5-1 plan during an open trading window and when they are not in possession of material nonpublic information.

Transactions With Related Persons and indemnification

Related-Person Transactions Policy and Procedures

In 2019, the Company adopted a written Related-Person Transactions Policy that sets forth the Company’s policies and procedures regarding the identification, review, consideration and approval or ratification of “related-persons transactions.” This policy covers, with certain exceptions set forth in Item 404 of Regulation S-K under the Securities Act of 1933, as amended (the “Securities Act”), any transaction, arrangement or relationship, or any series of similar transactions, arrangements or relationships in which we were or are to be a participant, where the amount involved exceeds $120,000, and a related person had or will have a direct or indirect material interest, including, without limitation, purchases of goods or services by or from the related person or entities in which the related person has a material interest, indebtedness, guarantees of indebtedness and employment by us of a related person. A related person is any executive officer, director, or more than 5% stockholder of the Company, including any of their immediate family members, and any entity owned or controlled by such persons. In reviewing and approving any such transactions, our Audit Committee is responsible for reviewing all relevant facts and circumstances, including, but not limited to, whether the transaction is on terms comparable to those that could be obtained in an arm’s length transaction and the extent of the related person’s interest in the transaction.

Certain Relationships and Related Transactions

Baker Brothers Nominating Agreement

On September 5, 2018, we entered into a nominating agreement (the “Baker Brothers. Nominating Agreement”), with Baker Brothers Life Sciences L.P. and 667, L.P. (together, the “Baker Brothers”). Pursuant

to the Baker Brothers Nominating Agreement, during the period beginning at the closing of our initial public offering until when Baker Brothers no longer beneficially own at least 3,333,333 shares of our common stock (subject to adjustment for stock splits, combinations, recapitalizations and similar transactions) (the “Nominating Agreement Period”), we will have the obligation to support the nomination of, and to cause our board of directors to include in the slate of nominees recommended to our stockholders for election, two individuals designated by Baker Brothers (each a “Baker Brothers Designee”), unless a majority of our disinterested directors reasonably and in good faith determines that a Baker Designee would not be qualified to serve as our director under law, rules of the stock exchange on which our shares are listed, our amended and restated bylaws, or any of our company policies. If a Baker Designee resigns his or her seat on our board of directors or is removed or does not become a director for any reason, the vacancy will be filled by the election or appointment of another designee of Baker Brothers as soon as reasonably practicable, subject to compliance with applicable laws, rules and regulations. Furthermore, during the Nominating Agreement Period, if there is no Baker Designee on our Board of Directors, we will have the obligation to invite two board of directors observer designees of Baker Brothers (the “Baker Observers”), to attend all meetings of our Board of Directors and all meetings of the committees of our Board of Directors as a nonvoting observer, subject to Baker Observers’ agreement to hold in confidence the information they receive as observers of our Board of Directors and committee meetings, as well as subject to their exclusion from our Board of Directors’ meetings to preserve our attorney-client privilege, to avoid conflicts of interest, if Baker Brothers is determined by our board of directors to be a competitor or other customary conditions. The Baker Brothers Nominating Agreement automatically terminates upon the earlier of when Baker Brothers, together with its affiliates, no longer beneficially owns at least 3,333,333 shares of our common stock or the consummation of our acquisition in a change of control transaction, as such terms are defined in our amended and restated certificate of incorporation.

The IRA provides these holders of our preferred stock with certain registration rights, including the right to demand that we file a registration statement or request that their shares be covered by a registration statement that we are otherwise filing, and also the right to obligate us to an agreement to provide for additional rights to demand that we file a registration statement or request that their shares be covered by a registration statement that we have filed and maintain as effective. In connection with our initial public offering, the holders of 17,248,259 shares of our Class A common stock issuable on conversion of outstanding shares of our preferred stock (including Class A common stock issuable upon conversion of Class B common stock) will be entitled to rights with respect to the registration of their shares of Class A common stock (including Class A common stock issuable upon conversion of Class B common stock) under the Securities Act under this agreement.

Registration Rights Agreement

Under the agreement, following a demand by Baker Brothers, we are obligated to file a resale registration statement on Form S-3, or other appropriate form, covering such common stock held by Baker Brothers, and to keep such registration statement effective until the earlier of (i) all registrable securities covered by the registration statement have been sold or may be sold freely without limitations or restrictions as to volume or manner of sale pursuant to Rule 144 of the Securities Act (“Rule 144”), or (ii) all registrable securities covered by the registration statement otherwise cease to be considered registrable securities pursuant to the terms of the agreement.

Serafini, one of our directors and our Chief Strategy Officer, is a partner of Cooley. During the years ended December 31, 2019 and 2020, we incurred and recorded approximately $2.7 million and $1.7 million, respectively, of legal expenses for services performed by Cooley.

During the years ended December 31, 2019 and 2020, we incurred and recorded approximately $1.4 million and $1.1 million, respectively, of legal expenses for services performed by Kilpatrick Townsend.

Indemnification Agreements

Section 145 of the Delaware General Corporation Law authorizes a court to award, or a corporation’s board of directors to grant, indemnity to directors and officers in terms sufficiently broad to permit such indemnification under certain circumstances for liabilities, including reimbursement for expenses incurred, arising under the Securities Act. Our amended and restated certificate of incorporation permits indemnification of our directors, officers, employees and other agents to the maximum extent permitted by the Delaware General Corporation Law, and our amended and restated bylaws provide that we will indemnify our directors and officers and permit us to indemnify our employees and other agents, in each case to the maximum extent permitted by the Delaware General Corporation Law.

We have entered into indemnification agreements with our directors and officers, whereby we have agreed to indemnify our directors and officers to the fullest extent permitted by law, including indemnification against expenses and liabilities incurred in legal proceedings to which the director or officer was, or is threatened to be made, a party by reason of the fact that such director or officer is or was a director, officer, employee or agent of Atreca, Inc., provided that such director or officer acted in good faith and in a manner that the director or officer reasonably believed to be in, or not opposed to, the best interest of Atreca, Inc. At present, there is no pending litigation or proceeding involving a director or officer of Atreca, Inc. regarding which indemnification is sought, nor is the registrant aware of any threatened litigation that may result in claims for indemnification.

We maintain insurance policies that indemnify our directors and officers against various liabilities arising under the Securities Act and the Exchange Act that might be incurred by any director or officer in his capacity as such.

Householding of Proxy Materials

The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for Notices of Internet Availability of Proxy Materials or other Annual Meeting materials with respect to two or more stockholders sharing the same address by delivering a single Notice of Internet Availability of Proxy Materials or other Annual Meeting 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.

This year, a number of brokers with account holders who are our stockholders will be “householding” the Company’s proxy materials. A single Notice of Internet Availability of 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 Notice of Internet Availability of Proxy Materials, please notify your broker, or notify us by sending your written request to Atreca, Inc., General Counsel and Corporate Secretary, 835 Industrial Rd., Suite 400, San Carlos, California 94070 or (650) 595-2595 and we will deliver a separate copy promptly. Stockholders who currently receive multiple copies of the Notices of Internet Availability of Proxy Materials at their addresses and would like to request “householding” of their communications should contact their brokers.
