What is the difference between holding shares as a stockholder of record and as a beneficial owner?
Most of our stockholders hold their shares in an account at a brokerage firm, bank or other nominee holder, rather than holding share certificates in their own name. As summarized below, there are some distinctions between shares held of record and those owned beneficiallybeneficially.
Stockholder of Record
If, on the Record Date, your shares were registered directly in your name with our transfer agent, Computershare, you are a “stockholder of record” who may vote at the Annual Meeting, and we are sending these proxy materials or the Notice directly to you. You can vote by proxy overvia the Internet or by telephone by following the instructions provided in the Notice, or, if you

requested printed copies of the proxy materials by mail, you can vote by mailing your proxy as described in the proxy materials.
Beneficial Owner
If, on the Record Date, your shares were held in an account at a brokerage firm or at a bank or other nominee holder, you are considered the beneficial owner of shares held “in streetin “street name,” and these proxy materials or the Notice are being forwarded to you by your broker or nominee who is considered the stockholder of record for purposes of voting at the Annual Meeting. As the beneficial owner, you have the right to direct your broker on how to vote your shares and to attend the Annual Meeting. However, since you are not the stockholder of record, you may not vote these shares in person at the Annual Meeting unless you receive a valid proxy from your brokerage firm, bank or other nominee holder. To obtain a valid proxy, you must make a special request of your brokerage firm, bank or other nominee holder. If you do not make this request, you can still vote by using the voting instruction card enclosed with this proxy statement; however, you will not be able to vote in person at the Annual Meeting.
What is the quorum required for the Annual Meeting?
The representation in person or by proxy of holders of at least a majority of the issued and outstanding shares of our common stock entitled to vote at the Annual Meeting is necessary to constitute a quorum for the transaction of business at the Annual


Meeting. For purposes of determining the presence of a quorum, abstentions and broker non-votes will be counted as present at the Annual Meeting.
Assuming that a quorum is present, what vote is required to approve the proposals to be voted upon at the Annual Meeting?

Say-on-Pay Proposal: The approval of this proposal requires the affirmative vote of a majority of the votes cast at the Annual Meeting. Because the Say-on-Pay Proposal is advisory, it will not be binding on Concert, our Board or any committee of our Board. However, our Board, including our compensation committee, values the opinions of our stockholders and, to the extent there are a substantial number of votes cast against the executive officer compensation as disclosed in this proxy statement, we will consider our stockholders’ concerns and evaluate what actions may be appropriate to address those concerns.
Say-on-Frequency Proposal: This proposal provides a choice among three frequency periods (every one, two or three years) for future non-binding, advisory say-on-pay votes. The frequency period that receives the most votes will be deemed to be the recommendation of our stockholders. However, because this vote is advisory and not binding on Concert or our Board, we may decide that it is in the best interests of our stockholders and Concert to hold a say-on-pay vote more or less frequently than the frequency period selected by a plurality of our stockholders.
Auditor Proposal: The ratification of the appointment of Ernst & Young LLP requires the affirmative vote of a majority of the shares present in person or represented by proxyvotes cast at a duly calledthe Annual Meeting.

CORPORATE GOVERNANCE
General
We believe that good corporate governance is important to ensure that the CompanyConcert is managed for the long-term benefit of our stockholders. This section describes key corporate governance practices that we have adopted. We have adopted a code of business conduct and ethics, which applies to all of our employees, officers directors and employees, anddirectors, corporate governance guidelines and charters for our audit committee, our compensation committee and our nominating and governance committee. We have posted copies of our code of business conduct and ethics and corporate governance guidelines, as well as each of our committee charters, on the “Corporate Governance” page of the “Investors” section of our website, www.concertpharma.com, which you can access free of charge. Information contained on theour website is not incorporated by reference in, or considered part of, this proxy statement. We intend to disclose on our website any amendments to, or waivers from, our code of business conduct and ethics that are required to be disclosed by law or NASDAQ listing standards.the Nasdaq Listing Rules. We will also provide copies of these documents as well as our other corporate governance documents, free of charge, to any stockholder upon written request to Concert Pharmaceuticals, Inc., 9965 Hayden Avenue, Suite 500,3000N, Lexington, MA 02421, Attention: Investor Relations.
Director Independence
Rule 5605 of the NASDAQNasdaq Listing Rules requires a majority of a listed company’s board of directors to be comprised of independent directors within one year of listing. In addition, the NASDAQNasdaq Listing Rules require that, subject to specified exceptions, each member of a listed company’s audit, compensation and nominating and corporate governance committees be independent, that audit committee members also satisfy heightened independence criteria set forthrequirements contained in Rule 10A-3 underof the Securities Exchange Act of 1934 (as amended, the “Exchange Act”Exchange Act) and that compensation committee members also satisfy heightened independence requirements contained in the NASDAQNasdaq Listing Rules, as well as Rule 10C-1 underof the Exchange Act.
Under Rule 5605(a)(2), a director will only qualify as an “independent director” if, in the opinion of our Board, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.
In order to be considered independent for purposes of Rule 10A-3, a member of an audit committee of a listed company may not, other than in his or her capacity as a member of the audit committee, the Board,board of director or any other board committee, accept, directly or indirectly, any consulting, advisory or other compensatory fee from the listed company or any of its subsidiaries or otherwise be an affiliated person of the listed company or any of its subsidiaries.
When determining the independence of the members of our compensation committee under the heightened independence requirements contained in the NASDAQNasdaq Listing Rules and Rule 10C-1, our Board is required to consider all factors specifically relevant to determining whether a director has a relationship with us that is material to that director’s ability to be independent from management in connection with the duties of a compensation committee member, including, but not limited to: (1) the source of compensation of that director, including any consulting, advisory or other compensatory fee paid by us to that director; and (2) whether that director is affiliated with the Company,Concert, a subsidiary of the CompanyConcert or an affiliate of a subsidiary of the Company.Concert.

Our Board has reviewed the composition of our Board and its committees and the independence of each director. Based upon information requested from and provided by each director concerning his background, employment and affiliations, including family relationships, our Board has determined that each of our directors, with the exception of Dr. Tung, is an “independent director” as defined under Rule 5605(a)(2) of the NASDAQNasdaq Listing Rules. Our Board also determined that Mr. Auchincloss, Dr. Jaeger and Ms. van Heek, who comprise our audit committee, and Mr. Aldrich, Dr. Barrett, Mr. Høiland and Ms. FitzGerald,Mr. Hutt, who comprise our compensation committee, satisfy the independence standards for such committees established by the SEC and the NASDAQNasdaq Listing Rules, as applicable.

Current members with qualifications and skills that are consistent with the nominating and corporate governance committee’s criteria for Board service and who are willing to continue in service are considered for re-nomination, balancing the value of continuity of service by existing members of our Board with that of obtaining a new perspective or expertise.
If any member of our Board does not wish to continue in service or if our Board decides not to re-nominate a member for re-election, the nominating and corporate governance committee identifies a new nominee that meets the criteria above. The nominating and corporate governance committee generally inquires of our Board and members of management for their recommendations. The nominating and corporate governance committee may also review the composition and qualification of the boards of directors of our competitors, and may seek input from industry experts or analysts. The nominating and corporate governance committee reviews the qualifications, experience and background of suggested candidates. Final candidates, if other than our current directors, would be interviewed by the members of the nominating and corporate governance committee and by certain of our other independent directors and executive management. In making its determinations, the nominating and corporate governance committee evaluates each individual in the context of our Board as a whole, with the objective of assembling a group that can best contribute to the success of the CompanyConcert and represent stockholder interests through the exercise of sound judgment. After review and deliberation of all feedback and data, the nominating and corporate governance committee makes its recommendation to our Board.

We have not received director candidate recommendations from our stockholders and do not have a formal policy regarding consideration of such recommendations. However, any recommendations received from stockholders will be evaluated in the same manner that potential nominees suggested by Board members, management or other parties are evaluated. We do not intend to treat stockholder recommendations in any manner differentdifferently from other recommendations.
Under our bylaws,by-laws, stockholders wishing to nominate a candidate for director should write to our corporate secretary.

Narrative to Summary Compensation Table
We review compensation annually for all employees, including our executives.executive officers. In setting executive officer base salaries and target incentive bonus levels, determining actual incentive bonus amounts and granting equity incentive awards, we consider compensation for comparable positions in the market, the historical compensation levels of our executives,executive officers, individual performance as compared to our expectations and objectives, our desire to motivate our employees to achieve short- and long-term results that are in the best interests of our stockholders, and a long-term commitment to our Company.Concert. We do not target a specific competitive position or a specific mix of compensation among base salary, bonus or long-term incentives.


Our compensation committee has primary responsibility for determining the compensation of our executive officers.officers other than our chief executive officer. Our Board has primary responsibility for determining the compensation of our chief executive officer based on the recommendation of our compensation committee. Our compensation committee typically reviews and discusses proposed compensation with theour chief executive officer for all executivesexecutive officers other than for the chief executive officer. The compensation committee, without the applicable members of management present, discusses recommendations for management and ultimately approves the compensation of our executive officers.himself. During 2017,2019, our compensation committee engaged Radford as its independent compensation consultant to review our executive compensation peer group and program design and to assist with assessing our executives’executive officers’ compensation relative to those at comparable companies. Our compensation committee considered the relationship that Radford has with us, the members of our Board of Directors and our executive officers. Based on the committee’s evaluation, the compensation committee has determined that Radford is independent and that theirits work has not raised any conflicts of interest.

Radford assisted the committee in conducting a competitive compensation assessment for our executive officers for the fiscal year ended December 31, 2017.2019. In evaluating the total compensation of our executive officers, the compensation committee, with the assistance of Radford, reviewed compensation information from our peer group companies. Radford then supplemented the peer group proxy information with published survey data, which provided a broader market representation of companies and deeper position reporting.

Using information provided by Radford, the compensation committee established a peer group of publicly traded companies in the biopharmaceutical and biotechnology industries that is selected based on a balance of the following criteria:

companies whose number of employees, stage of development and market capitalization are similar, though not necessarily identical, to ours;
companies with similar executive positions to ours;
companies against which we believe we compete for executive talent; and
public companies based in the United States whose compensation and financial data are available in proxy statements or through widely available compensation surveys.

Based on these criteria, our peer group for 2017 was comprised of the following 21 publicly traded companies:
Achillion Pharmaceuticals, Inc.Genocea Biosciences, Inc.Paratek Pharmaceuticals, Inc.
Agenus, Inc.Geron CorporationSangamo Biosciences, Inc.
Akebia Therapeutics, Inc.GlycoMimetics, Inc.Selecta Biosciences, Inc.

Base salary. In 2017, the base salaries for Dr. Tung, Dr. Cassella, and Ms. Stuart were $517,402, $406,445 and $398,247, respectively. We use base salaries to recognize the experience, skills, knowledge and responsibilities required of all our employees, including our named executive officers. None of our named executive officers is currently party to an employment agreement or other agreement or arrangement that provides for automatic or scheduled increases in base salary. The 2019 base salaries for our named executive officers are set forth in the following table.

Annual bonus. Pursuant to our executive bonus program for 2017,2019, our Board of Directors established and approved annual bonus targets based on the achievement of specified corporate goals. The target bonus amounts for the named executive officers were 50% of base salary for Dr. Tung and 40% of base salary for each of Dr. Cassella and Ms. Stuart. Our corporate goals are typically focused on the achievement of specific research, clinical, regulatory,research, financial and strategic goals. We consider these to be difficult to attain, conducive to the creation of stockholder value and designed to contribute to our current and future financial success. The corporate goals for 2017 were to identify new candidate compounds, partner our CTP-656 program, advance our CTP-543 program, and raise capital.

In January 2018, the2020, our compensation committee, and our Board with respect to our chief executive officer, conducted a review to determine and approve the attainment of such goals and to assess the individual performance of each of our named executive officers. Based uponon such review and assessment, theour compensation committee, and our Board with respect to our chief executive officer, approved cash incentive bonus payments for each of our named executive officers. The target bonus amounts for the named executive officers, as a percentage of base salary, and the actual bonuses for our named executive officers approved by our compensation committee or Board, as a percentage of $297,506 to Dr. Tung, $186,965 to Dr. Cassella and $183,194 to Ms. Stuart for 2017.target bonus, are set forth in the following table.

Equity incentives. Although we do not have a formal policy with respect to the grant of equity incentive awards to our executive officers, or any formal equity ownership guidelines applicable to them, we believe that equity grants provide our executivesexecutive officers with a strong link to our long-term performance, create an ownership culture and help to align the interests of our executivesexecutive officers and our stockholders. In addition, we believe that equity grants with a time-based vesting feature promote executive retention because this feature incentivizes our executive officers to remain in our employment during the vesting period. Accordingly, we typically grant stock option awards at the start of employment to each executive officer and our other employees, and our compensation committee and Board of Directors periodically review the equity incentive compensation of our named executive officers and other employees, and from time to time, may grant equity incentive awards to them in the form of stock options.them.
For stock options, the option exercise price is equal toequals the fairclosing market valueprice of our common stock on the date of grant. Time vested stock option grants made in connection with the commencement of employment with us typically vest 25% on the first anniversary of the date of grant or, if earlier, the initial employment date (the "vesting commencement date"), and 6.25% vest per quarter thereafter, through the fourth anniversary of the vesting commencementinitial employment date.

CERTAIN RELATIONSHIPS AND RELATED PERSON TRANSACTIONS
Policies and Procedures for Related Person Transactions
Our Board has adopted a written related person transaction policy that sets forth policies and procedures for the review and approval or ratification of related person transactions. This policy covers any transaction, arrangement or relationship, or any series of similar transactions, arrangements or relationships, in which we were or are to be a participant, 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.
Our related person transaction policy contains exceptions for any transaction or interest that is not considered a related person transaction under SEC rules as in effect from time to time. In addition, the policy provides that an interest arising solely from a related person’s position as an executive officer of another entity that is a participant in a transaction with us will not be subject to the policy if each of the following conditions is met:
the related person and all other related persons own in the aggregate less than a 10% equity interest in such entity;
the related person and his or her immediate family members are not involved in the negotiation of the terms of the transaction with us and do not receive any special benefits as a result of the transaction; and
the amount involved in the transaction equals less than the greater of $200,000 or 5% of the annual gross revenue of the company receiving payment under the transaction.
The policy provides that any related person transaction proposed to be entered into by us must be reported to our general counsel and will be reviewed and approved by our audit committee in accordance with the terms of the policy, prior to effectiveness or consummation of the transaction whenever practicable. The policy provides that if our chief financial officer determines that advance approval of a related person transaction is not practicable under the circumstances, our audit committee will review and, in its discretion, may ratify the related person transaction at the next meeting of the audit committee. The policy also provides that alternatively, our chief financial officer may present a related person transaction arising in the time period between meetings of the audit committee to the chair of the audit committee, who will review and may approve the related person transaction, subject to ratification by the audit committee at the next meeting of the audit committee.
In addition, the policy provides that any related person transaction previously approved by the audit committee or otherwise already existing that is ongoing in nature will be reviewed by the audit committee annually to ensure that such related person transaction has been conducted in accordance with the previous approval granted by the audit committee, if any, and that all required disclosures regarding the related person transaction are made.
The policy provides that transactions involving compensation of executive officers will be reviewed and approved by our compensation committee in the manner to be specified in the charter of the compensation committee.
A related person transaction reviewed under this policy will be considered approved or ratified if it is authorized by the audit committee in accordance with the standards set forth in the policy after full disclosure of the related person’s interests in the transaction. As appropriate for the circumstances, the policy provides that the audit committee will review and consider:
the related person’s interest in the related person transaction;
the approximate dollar value of the amount involved in the related person transaction;
the approximate dollar value of the amount of the related person’s interest in the transaction without regard to the amount of any profit or loss;
whether the transaction was undertaken in the ordinary course of business of the Company;
whether the transaction with the related person is proposed to be, or was, entered into on terms no less favorable to us than the terms that could have been reached with an unrelated third party;

the purpose of, and the potential benefits to us of, the transaction; and
any other information regarding the related person transaction or the related person in the context of the proposed transaction that would be material to investors in light of the circumstances of the particular transaction.
The policy provides that the audit committee will review all relevant information available to it about the related person transaction. The policy provides that the audit committee may approve or ratify the related person transaction only if the audit committee determines that, under all of the circumstances, the transaction is in, or is not inconsistent with, our best interests. The policy provides that the audit committee may, in its sole discretion, impose such conditions as it deems appropriate on us or the related person in connection with approval of the related person transaction.
No related person transactions were brought to the attention of the audit committee for consideration in 2017.



SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE
Delinquent Section 16(a) of the Exchange Act requires our directors, executive officers, and persons holding more than 10% of the Company’s common stock to report their initial ownership of the common stock and other equity securities and any changes in that ownership in reports that must be filed with the SEC. The SEC has designated specific deadlines for these reports, and we must identify in this proxy statement those persons who did not file these reports when due.Reports
Based solely on a review of reports furnished to us orand written representations from reportingthe persons required to file reports pursuant to Section 16(a) of the Exchange Act, we believe allthat, during the year ended December 31, 2019, our directors, executive officers and holders of more than 10% owners timely filedof our common stock complied with all reports regarding transactions in the Company’s securities required to be filed for 2017 by Section 16(a) under the Exchange Act.filing requirements applicable to them, except that a Form 4 to report a purchase of our common stock by Christine van Heek on August 2, 2019 was not filed until October 10, 2019.


PROPOSAL NO. 2—2 – NON-BINDING, ADVISORY VOTE ON EXECUTIVE COMPENSATION
We are providing our stockholders the opportunity to vote to approve, on a non-binding, advisory basis, the compensation of our named executive officers as disclosed in this proxy statement in accordance with the SEC’s rules. This proposal, which is commonly referred to as “say-on-pay,” is required by the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, which added Section 14A to the Exchange Act. Section 14A of the Exchange Act also requires that stockholders have the opportunity to cast a non-binding, advisory vote with respect to whether future executive compensation advisory votes will be held every one, two or three years, which is commonly referred to as “say-on-frequency” and is the subject of Proposal No. 3.
Our executive compensation program is designed to attract, motivate and retain our named executive officers, who are critical to our success. Under this program, our named executive officers are rewarded for the achievement of our short- and long-term financial and strategic goals and for driving corporate financial performance and stability. The program contains elements of cash and equity-based compensation and is designed to align the interests of our named executive officers with those of our stockholders. We believe that our compensation program strikes an appropriate balance between the implementation of responsible, measured compensation practices and the effective provision of incentives for our named executive officers to exert their best efforts for our success.
The “Executive Compensation” section of this proxy statement describes our executive compensation program and the decisions made by our compensation committee and our Board with respect to the year ended December 31, 2019. Our executive compensation program embodies a pay-for-performance philosophy that supports our business strategy and aligns the interests of our named executive officers with our stockholders. Our Board believes that this link between compensation and the achievement of our short- and long-term business objectives has helped drive our performance over time. At the same time, we believe that our program does not encourage excessive risk-taking by management. This vote is not intended to address any specific item of compensation, but rather the overall compensation of our named executive officers and the policies and practices described in this proxy statement.
Our Board is asking stockholders to approve a non-binding, advisory vote on the following resolution:
RESOLVED, that the compensation paid to Concert’s named executive officers, as disclosed pursuant to the compensation disclosure rules of the Securities and Exchange Commission, the compensation tables and any related material disclosed in this proxy statement, is hereby approved on a non-binding, advisory basis.
As an advisory vote, this proposal is not binding. The outcome of this advisory vote does not overrule any decision by us or our Board (or any committee thereof), create or imply any change to the fiduciary duties of us or our Board (or any committee thereof), or create or imply any additional fiduciary duties for us or our Board (or any committee thereof). However, our compensation committee and our Board value the opinions expressed by our stockholders in their vote on this proposal and will consider the outcome of the vote when making future compensation decisions for our named executive officers.
Recommendation of our Board
OUR BOARD UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE FOR APPROVAL, ON A NON-BINDING, ADVISORY BASIS, OF THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS.


PROPOSAL NO. 3 – NON-BINDING, ADVISORY VOTE ON THE FREQUENCY OF FUTURE NON-BINDING, ADVISORY VOTES ON EXECUTIVE COMPENSATION
We are asking stockholders to cast a non-binding, advisory vote regarding the frequency of future non-binding, advisory votes on executive compensation. Stockholders may vote for a frequency of every one, two or three years, or may abstain.
Our Board believes that an annual executive compensation advisory vote will facilitate more direct stockholder input about executive compensation and is consistent with our policy of reviewing our compensation program annually and with us being accountable to our stockholders on corporate governance and executive compensation matters. This feedback may then be considered by our Board in its annual decision-making process. For these reasons, we believe that an annual vote would be the best governance practice for us at this time.
Our Board values the opinions of our stockholders and will take into consideration the outcome of this vote in deciding on the frequency of future non-binding, advisory votes on executive compensation. However, because this vote is non-binding and advisory, our Board may decide that it is in the best interests of our stockholders and Concert to hold the advisory vote to approve executive compensation more or less frequently than the option selected by a plurality of our stockholders.
Recommendation of our Board
OUR BOARD UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE TO HOLD FUTURE NON-BINDING, ADVISORY VOTES ON EXECUTIVE COMPENSATION EVERY ONE YEAR.

Notwithstanding the foregoing, pre-approval is not required with respect to the provision of services, other than audit, review or attest services, by the independent auditor if the aggregate amount of all such services is no more than 5% of the total amount paid by us to the independent auditor during the fiscal year in which the services are provided, such services were not recognized by us at the time of the engagement to be non-audit services and such services are promptly brought to the attention of the audit committee and approved prior to completion of the audit by the audit committee.
From time to time, our audit committee may pre-approve services that are expected to be provided to us by the independent auditor during the following 12 months. At the time such pre-approval is granted, the audit committee must identify the particular pre-approved services in a sufficient level of detail so that our management will not be called upon to make a judgment as to whether a proposed service fits within the pre-approved services and, at each regularly


scheduled meeting of the audit committee following such approval, management or the independent auditor shall report to the audit committee

regarding each service actually provided to us pursuant to such pre-approval.
