NOTICE OF 2015 ANNUAL MEETING OF STOCKHOLDERS

        Notice is hereby given that the 2015 Annual Meeting of Stockholders of T2 Biosystems, Inc. will be held on Friday, June 19, 2015, at 9 a.m. Eastern Time, at our headquarters located at 101 Hartwell Ave., Lexington, Massachusetts 02421. The purpose of the meeting is the following:

            1.     to elect two directors, John McDonough and Harry Wilcox, to serve as Class I directors until the 2018 annual meeting of stockholders and until their successors are duly elected and qualified, subject to their earlier resignation or removal;

            2.     to ratify the appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2015; and

            3.     to transact such other business as may properly come before the meeting or at any and all adjournments or postponements thereof.

        The proposal for the election of directors relates solely to the election of Class I directors nominated by the Board of Directors.

        Only T2 Biosystems, Inc. stockholders of record at the close of business on April 20, 2015 will be entitled to vote at the meeting and any adjournment or postponement thereof.

        We are pleased to take advantage of Securities and Exchange Commission rules that allow companies to furnish their proxy materials over the Internet. We are mailing to many of our stockholders a Notice of Internet Availability of Proxy Materials instead of a paper copy of our proxy materials and our 2014 Annual Report on Form 10-K. The Notice contains instructions on how to access those documents and to cast your vote via the Internet. The Notice also contains instructions on how to request a paper copy of our proxy materials and our 2014 Annual Report on Form 10-K. All stockholders who do not receive a Notice will receive a paper copy of the proxy materials and the Annual Report by mail. This process allows us to provide our stockholders with the information they need on a more timely basis, while reducing the environmental impact and lowering the costs of printing and distributing our proxy materials.

        Your vote is important. Whether or not you are able to attend the meeting in person, it is important that your shares be represented.

PROXY STATEMENT
FOR THE 2015 ANNUAL MEETING OF STOCKHOLDERS


GENERAL INFORMATION

        Our Board of Directors (the "Board of Directors" or "Board") has made this Proxy Statement and related materials available to you on the Internet, or at your request has delivered printed versions to you by mail, in connection with the Board of Directors' solicitation of proxies for our 2015 Annual Meeting of Stockholders (the "Annual Meeting"), and any adjournment of the Annual Meeting. If you requested printed versions of these materials by mail, they will also include a proxy card for the Annual Meeting.

        Pursuant to rules adopted by the Securities and Exchange Commission ("SEC"), we are providing access to our proxy materials over the Internet. Accordingly, we are sending a Notice of Internet Availability of Proxy Materials (the "Notice") to our stockholders of record and beneficial owners as of the record date identified below. The mailing of the Notice to our stockholders is scheduled to begin by April 30, 2015.

        IMPORTANT NOTICE REGARDING THE INTERNET AVAILABILITY OF PROXY MATERIALS FOR THE ANNUAL STOCKHOLDERS MEETING TO BE HELD ON JUNE 19, 2015: This proxy statement, the accompanying proxy card or voting instruction card and our 2015 Annual Report on Form 10-K are available at http://www.proxyvote.com.

        In this Proxy Statement, the terms "T2 Biosystems," "we," "us," and "our" refer to T2 Biosystems, Inc. The mailing address of our principal executive offices is T2 Biosystems, Inc., 101 Hartwell Ave., Lexington, MA 02421.

EXPLANATORY NOTE

        We are an "emerging growth company" under applicable federal securities laws and therefore permitted to take advantage of certain reduced public company reporting requirements. As an emerging growth company, we provide in this proxy statement the scaled disclosure permitted under the Jumpstart Our Business Startups Act of 2012 (the "JOBS Act"), including the compensation disclosures required of a "smaller reporting company," as that term is defined in Rule 12b-2 promulgated under the Securities Exchange Act of 1934. In addition, as an emerging growth company, we are not required to conduct votes seeking approval, on an advisory basis, of the compensation of our named executive officers or the frequency with which such votes must be conducted. We will remain an "emerging growth company" until the earliest of (i) the last day of the fiscal year in which we have total annual gross revenues of $1 billion or more; (ii) December 31, 2017; (iii) the date on which we have issued more than $1 billion in nonconvertible debt during the previous three years; or (iv) the date on which we are deemed to be a large accelerated filer under the rules of the SEC.

Stockholders Entitled to Vote; Record Date

        As of the close of business on April 20, 2015, the record date for determination of stockholders entitled to vote at the Annual Meeting, there were outstanding 20,204,969 shares of our common stock, par value $0.001 per share, all of which are entitled to vote with respect to all matters to be acted upon at the Annual Meeting. Each stockholder of record is entitled to one vote for each share of our common stock held by such stockholder. No shares of T2 Biosystems preferred stock were outstanding as of April 20, 2015.

Table of Contents

Quorum; Abstentions; Broker Non-Votes

        Our By-laws provide that a majority of the shares entitled to vote, present in person or represented by proxy, will constitute a quorum for the transaction of business at the Annual Meeting. Under the General Corporation Law of the State of Delaware, shares that are voted "abstain" or "withheld" and broker "non-votes" are counted as present for purposes of determining whether a quorum is present at the Annual Meeting.

        Under our By-laws, any proposal other than an election of directors is decided by a majority of the votes properly cast for and against such proposal, except where a larger vote is required by law or by our Certificate of Incorporation or By-laws. Abstentions and broker "non-votes" are not included in the tabulation of the voting results on any such proposal and, therefore, do not have the effect of votes in opposition to such proposals. A broker "non-vote" occurs when a nominee holding shares for a beneficial owner does not vote on a particular proposal because the nominee does not have discretionary voting power with respect to that item and has not received instructions from the beneficial owner.

        If your shares are held in "street name" by a brokerage firm, your brokerage firm is required to vote your shares according to your instructions. If you do not give instructions to your brokerage firm, the brokerage firm will still be able to vote your shares with respect to certain "discretionary" items, but will not be allowed to vote your shares with respect to "non-discretionary" items. Proposal 1 is a "non-discretionary" item. If you do not instruct your broker how to vote with respect to those proposals, your broker may not vote for those proposals, and those votes will be counted as broker "non-votes." Proposal 2 is considered to be a discretionary item, and your brokerage firm will be able to vote on this proposal even if it does not receive instructions from you.

Voting

    In Person

        If you are a stockholder of record, you may vote in person at the meeting. We will give you a ballot when you arrive. If you hold your shares through a bank or broker and wish to vote in person at the meeting, you must obtain a valid proxy from the firm that holds your shares. No appraisal rights are available under Delaware Law or under the Current Certificate or the Company's Amended and Restated Bylaws to any stockholder who dissents from this proposal.

    By Proxy

        If you do not wish to vote in person or will not be attending the meeting, you may vote by proxy. You can vote by proxy over the Internet 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. You may also authorize another person or persons to act for you as proxy in a writing, signed by you or your authorized representative, specifying the details of those proxies' authority. The original writing must be given to each of the named proxies, although it may be sent to them by electronic transmission if, from that transmission, it can be determined that the transmission was authorized by you. If you complete and submit your proxy before the meeting, the persons named as proxies will vote the shares represented by your proxy in accordance with your instructions. If you submit a proxy without giving voting instructions, your shares will be voted in the manner recommended by the Board of Directors on all matters presented in this Proxy Statement, and as the persons named as proxies may determine in their discretion with respect to any other matters properly presented at the meeting.

        If any other matters are properly presented for consideration at the Annual Meeting, including, among other things, consideration of a motion to adjourn the Annual Meeting to another time or place

Table of Contents

(including, without limitation, for the purpose of soliciting additional proxies), the persons named in the enclosed proxy card and acting thereunder will have discretion to vote on those matters in accordance with their best judgment. We do not currently anticipate that any other matters will be raised at the Annual Meeting.

Revocability of Proxy

        You may revoke your proxy by (1) following the instructions on the Notice and entering a new vote by mail or over the Internet before the Annual Meeting or (2) attending the Annual Meeting and voting in person (although attendance at the Annual Meeting will not in and of itself revoke a proxy). Any written notice of revocation or subsequent proxy card must be received by our Secretary prior to the taking of the vote at the Annual Meeting. Such written notice of revocation or subsequent proxy card should be hand delivered to our Secretary or sent to our principal executive offices at T2 Biosystems, Inc., 101 Hartwell Ave., Lexington, MA 02421, Attention: Corporate Secretary.

        If a broker, bank, or other nominee holds your shares, you must contact them in order to find out how to change your vote.

Expenses of Solicitation

        T2 Biosystems is making this solicitation and will pay the entire cost of preparing and distributing the Notice and these proxy materials and soliciting votes. If you choose to access the proxy materials or vote over the Internet, you are responsible for any Internet access charges that you may incur. Our officers and employees may, without compensation other than their regular compensation, solicit proxies through further mailings, personal conversations, facsimile transmissions, e-mails, or otherwise. We have hired Broadridge Financial Solutions, Inc. to assist us in the distribution of proxy materials and the solicitation of votes described above. Proxy solicitation expenses that we will pay include those for preparation, mailing, returning, and tabulating the proxies.

Procedure for Submitting Stockholder Proposals

        Stockholder proposals intended to be presented at the next annual meeting of our stockholders must satisfy the requirements set forth in the advance notice provision under our By-laws. To be timely for our next annual meeting of stockholders, any such proposal must be delivered in writing to our Secretary at our principal executive offices between the close of business on February 21, 2016, and March 21, 2016. If the date of the next annual meeting of the stockholders is scheduled to take place before May 20, 2016, or after August 18, 2016, notice by the stockholder must be delivered no earlier than the 120th day prior to such annual meeting and no later than the close of business on the later of (1) the 90th day prior to such annual meeting or (2) the 10th day following the day on which public announcement of the date of such meeting is first made.

        In addition, any stockholder proposal intended to be included in the proxy statement for the next annual meeting of our stockholders must also satisfy the SEC regulations under Rule 14a-8 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and be received not later than December 31, 2015. If the date of the annual meeting is moved by more than 30 days from the date contemplated at the time of the previous year's proxy statement, then notice must be received within a reasonable time before we begin to print and send proxy materials. If that happens, we will publicly announce the deadline for submitting a proposal in a press release or in a document filed with the SEC.

OVERVIEW OF PROPOSALS

        This Proxy Statement contains two proposals requiring stockholder action. Proposal 1 requests the election of two directors to the Board of Directors. Proposal 2 requests the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2015. Each of the proposals is discussed in more detail in the pages that follow.


PROPOSAL 1

ELECTION OF DIRECTORS

        The Board of Directors is divided into three classes. One class is elected each year at the annual meeting of stockholders for a term of three years. Vacancies on the Board of Directors are filled exclusively by the affirmative vote of a majority of the remaining directors, even if less than a quorum is present, and not by stockholders. A director elected by the Board of Directors to fill a vacancy in a class shall hold office for the remainder of the full term of that class, and until the director's successor is duly elected and qualified or until his or her earlier resignation, death, or removal.

        The terms of the Class I directors are scheduled to expire on the date of the upcoming Annual Meeting. Based on the recommendation of the nominating and corporate governance committee of the Board of Directors, the Board of Directors' nominees for election by the stockholders are two of the current Class I members: John McDonough and Harry Wilcox. If elected, each nominee will serve as a director until the annual meeting of stockholders in 2018 and until his successor is duly elected and qualified, or until his earlier death, resignation, or removal. Alan Crane, a current Class I member, is not standing for re-election and will no longer serve on our Board of Directors following the Annual Meeting.

        The names of and certain information about the directors in each of the three classes are set forth below. There are no family relationships among any of our directors or executive officers.

        It is intended that the proxy in the form presented will be voted, unless otherwise indicated, for the election of the Class I director nominees to the Board of Directors. If any of the nominees should for any reason be unable or unwilling to serve at any time prior to the Annual Meeting, the proxies will be voted for the election of such substitute nominee as the Board of Directors may designate.

Vote Required and Board of Directors' Recommendation

        Directors will be elected by a plurality of the votes cast by the stockholders entitled to vote on this proposal at the Annual Meeting.

        The proposal for the election of directors relates solely to the election of Class I directors nominated by the Board of Directors.

The Board of Directors recommends that stockholders vote FOR the election of
each of the Class I director nominees listed above.


PROPOSAL 2

RATIFICATION OF APPOINTMENT OF INDEPENDENT AUDITORS

        The audit committee has appointed Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2015. The Board of Directors recommends that stockholders vote for ratification of this appointment. If this proposal is not approved at the Annual Meeting, the audit committee will reconsider its appointment. Even if the appointment is ratified, the audit committee may, in its discretion, direct the appointment of a different independent registered accounting firm at any time during the year if the audit committee determines that such a change would be in our stockholders' best interests.

        Ernst & Young LLP has audited our financial statements for the fiscal years ended December 31, 2014 and 2013. We expect representatives of Ernst & Young LLP to be present at the Annual Meeting and available to respond to appropriate questions. They will have the opportunity to make a statement if they desire to do so.

        All Ernst & Young LLP services and fees in the fiscal years ended December 31, 2014 and December 31, 2013 were pre-approved by the audit committee. The fees for the year-end audit for the fiscal year ended December 31, 2014 were also approved by the audit committee.

Vote Required and Board of Directors' Recommendation

        The approval of Proposal 2 requires that a majority of the votes properly cast vote FOR this proposal. Shares that are voted "abstain" will not affect the outcome of this proposal.

The Board of Directors recommends that stockholders vote FOR ratification of the appointment of
Ernst & Young LLP as our independent registered public accounting firm.


TRANSACTION OF OTHER BUSINESS

        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 such matters in accordance with their best judgment.


SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

        The following table sets forth certain information regarding beneficial ownership of our common stock as of April 20, 2015, for: each person known to us to be the beneficial owner of more than five percent of our outstanding common stock; each of our named executive officers; each of our directors and nominees; and all of our directors and executive officers as a group.

        Beneficial ownership is determined in accordance with the rules of the SEC and generally includes voting or investment power with respect to securities. Except as noted by footnote, and subject to community property laws where applicable, we believe based on the information provided to us that the persons and entities named in the table below have sole voting and investment power with respect to all shares of our common stock shown as beneficially owned by them.

        The table lists applicable percentage ownership based on 20,041,645 shares of our common stock outstanding as of December 31, 2014. The number of shares beneficially owned includes shares of our common stock that each person has the right to acquire within 60 days of December 31, 2014, including upon the exercise of stock options. These stock options shall be deemed to be outstanding for the purpose of computing the percentage of outstanding shares of our common stock owned by such

RELATED PERSON TRANSACTIONS

Policies for Approval of Related Person Transactions

        We have adopted a written policy that transactions with directors, officers and holders of 5% or more of our voting securities and their affiliates, or each, a related party, must be approved by our audit committee or another independent body of our Board of Directors. All related party transactions shall be disclosed in our applicable filings with the Securities and Exchange Commission as required under SEC rules.

Transactions with Related Persons

        Based on a review of the transactions and arrangements between us and any related person or related person's affiliate, we describe below the transactions or arrangements during the year ended December 31, 2014 in which any related person or related person affiliate has a direct or indirect material interest and the amount involved exceeds $120,000.

        Employment Agreements.    We have entered into employment agreements with certain of our executive officers. See the "Executive Compensation" section for further details.

        Indemnification Agreements with Executive Officers and Directors.    We have entered into an indemnification agreement with each of our directors and executive officers. These indemnification agreements and our certificate of incorporation and our bylaws indemnify each of our directors and officers to the fullest extent permitted by the General Corporation Law of the State of Delaware. See the "Director Compensation—Limitation of Liability and Indemnification Agreements" section for further details.

        Limitation of Liability and Indemnification Agreements    We have adopted provisions in our certificate of incorporation and bylaws that limit or eliminate the personal liability of our directors to the fullest extent permitted by the DGCL, as it now exists or may in the future be amended.

12


Table of Contents

Consequently, a director will not be personally liable to us or our stockholders for monetary damages or breach of fiduciary duty as a director, except for liability for:

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

    any act or omission not in good faith or that involves intentional misconduct or a knowing violation of law;

    any unlawful payments related to dividends or unlawful stock purchases, redemptions or other distributions; or

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

        These limitations of liability do not alter director liability under the federal securities laws and do not affect the availability of equitable remedies such as an injunction or rescission.

        In addition, our bylaws provide that:

    we will indemnify our directors, officers and, in the discretion of our Board of Directors, certain employees to the fullest extent permitted by the DGCL, as it now exists or may in the future be amended; and

    we will advance reasonable expenses, including attorneys' fees, to our directors and, in the discretion of our Board of Directors, to our officers and certain employees, in connection with legal proceedings relating to their service for or on behalf of us, subject to limited exceptions.

        We have entered into indemnification agreements with each of our directors and executive officers. These agreements provide that we will indemnify each of our directors, such executive officers and, at times, their affiliates to the fullest extent permitted by Delaware law. We will advance expenses, including attorneys' fees (but excluding judgments, fines and settlement amounts), to each indemnified director, executive officer or affiliate in connection with any proceeding in which indemnification is available and we will indemnify our directors and officers for any action or proceeding arising out of that person's services as a director or officer brought on behalf of us and/or in furtherance of our rights. Additionally, each of our directors may have certain rights to indemnification, advancement of expenses and/or insurance provided by their affiliates, which indemnification relates to and might apply to the same proceedings arising out of such director's services as a director referenced herein. Nonetheless, we have agreed in the indemnification agreements that our obligations to those same directors are primary and any obligation of the affiliates of those directors to advance expenses or to provide indemnification for the expenses or liabilities incurred by those directors are secondary.

        We also maintain general liability insurance which covers certain liabilities of our directors and officers arising out of claims based on acts or omissions in their capacities as directors or officers, including liabilities under the Securities Act.

        Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers, or persons controlling the registrant under the foregoing provisions, we have been informed that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.


COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

        During 2014, Messrs. Lapidus, Crane and Carella served as members of our compensation committee. None of the members of our compensation committee has at any time during the last fiscal year been one of our officers or employees or had any relationship requiring disclosure under Item 404 of Regulation S-K. None of the members of our compensation committee is a former officer of the Company. None of our executive officers currently serves, or in the past fiscal year has served, as a member of the Board of Directors or compensation committee of any entity that has one or more executive officers serving on our Board of Directors or compensation committee.

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

        Section 16(a) of the Exchange Act requires our officers and directors and persons who beneficially own more than 10% of our outstanding common stock (collectively, "Reporting Persons") to file reports of beneficial ownership and changes in beneficial ownership with the SEC. Reporting Persons are required by SEC regulations to furnish us with copies of all Section 16(a) forms they file. Based on our records and other information, we believe that during the fiscal year ended December 31, 2014, all Reporting Persons complied with all Section 16(a) reporting requirements, except that one Form 4 for Sarah Kalil was inadvertently filed late.

CORPORATE GOVERNANCE

Board and Committee Matters

        Board Leadership and Independence.    Our Board of Directors has determined that all members of the Board of Directors, except John McDonough, are independent, as determined in accordance with the rules of the NASDAQ Stock Market. In making such independence determination, the Board of Directors considered the relationships that each such non-employee director has with us and all other facts and circumstances that the Board of Directors deemed relevant in determining their independence, including the beneficial ownership of our capital stock by each non-employee director. In considering the independence of the directors listed above, our Board of Directors considered the association of our directors with the holders of more than 5% of our common stock. There are no family relationships among any of our directors or executive officers.

        The positions of our Chairman of the Board and Chief Executive Officer are presently separated. Separating these positions allows our Chief Executive Officer to focus on our day-to-day business, while allowing the Chairman of the 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 must devote to his position in the current business environment, as well as the commitment required to serve as our Chairman, particularly as the Board of Directors' oversight responsibilities continue to grow. Our Board of Directors also believes that this structure ensures a greater role for the non-management directors in the oversight of our company and active participation of the independent directors in setting agendas and establishing priorities and procedures for the work of our Board of Directors. Our Board of Directors believes its administration of its risk oversight function has not affected its leadership structure. Although our amended and restated bylaws do not require our Chairman and Chief Executive Officer positions to be separate, our Board of Directors believes that having separate positions is the appropriate leadership structure for us at this time.

        Board Meetings and Committees.    Our Board of Directors held seven meetings during 2014. The independent directors regularly hold executive sessions at meetings of the Board of Directors. During 2014, each of the directors then in office attended at least 75% of the aggregate of all meetings of the Board of Directors and all meetings of the committees of the Board of Directors on which such director then served. Now that we are a public company, continuing directors and nominees for election as directors in a given year are encouraged to attend the annual meeting of stockholders. This is our first annual meeting of stockholders since we became a public company in August 2014.

        Stockholder Communications.    Any stockholder wishing to communicate with our Board of Directors, a particular director or the chair of any committee of the Board of Directors may do so by sending written correspondence to our principal executive offices, to the attention of the Chair, Nominating and Corporate Governance Committee. All such communications will be delivered to the Board of Directors or the applicable director or committee chair.

Table of Contents

        During 2014, our Board of Directors had four standing committees: audit committee, compensation committee, nominating and corporate governance committee and technology committee.

    Audit Committee.

        David Elsbree, Michael Cima and Harry Wilcox currently serve on the audit committee, which is chaired by David Elsbree. Our Board of Directors has determined that each member of the audit committee is "independent" for audit committee purposes as that term is defined in the rules of the SEC and the applicable NASDAQ Stock Market rules. Our Board of Directors has designated David Elsbree as an "audit committee financial expert," as defined under the applicable rules of the SEC. The audit committee's responsibilities include:

    appointing, overseeing the independence of, and setting the compensation of our independent auditor;

    overseeing the work of the independent auditor, including through the receipt and consideration of reports from such firm;

    reviewing and discussing with management and our independent auditor our annual and quarterly financial statements and related disclosures;

    coordinating the Board's oversight of our internal control over financial reporting, disclosure controls and procedures and our code of conduct;

    discussing our risk management and risk assessment policies;

    establishing procedures for the receipt, retention and treatment of complaints regarding accounting, internal accounting controls or auditing matters;

    reviewing the company's policies and procedures for reviewing and approving or ratifying any related person transactions;

    meeting independently with our internal auditing staff, if any, independent auditors and management; and

    preparing the audit committee report included below.

        The audit committee held four meetings during 2014. The audit committee operates under a written charter that satisfies the applicable standards of the SEC and NASDAQ. A copy of the audit committee charter is attached as Appendix A to this Proxy Statement.

    Compensation Committee.

        Stanley Lapidus, Alan Crane and Thomas Carella currently serve on the compensation committee, which is chaired by Stanley Lapidus. Under NASDAQ Stock Market rules, we are permitted to phase in our compliance with the independent compensation committee requirements set forth in NASDAQ Marketplace Rule 5605(d). Our Board of Directors has determined that each of Stanley Lapidus, Alan Crane and Thomas Carella is "independent" as that term is defined in the applicable NASDAQ Stock Market rules. In connection with Mr. Crane not standing for re-election as a Class I director at the Annual Meeting, we may appoint another member of our Board of Directors who satisfies these independence and other criteria to the compensation committee. The compensation committee's responsibilities include:

    reviewing and approving, or recommending for approval by our Board of Directors, our Chief Executive Officer's compensation;

    reviewing and approving, or recommending for approval by our Board of Directors with respect to, the compensation of our other executive officers;

    reviewing and making recommendations to our Board of Directors with respect to director compensation;

    reviewing and discussing annually with management our "Compensation Discussion and Analysis," if applicable; and

        The Compensation Committee held five meetings during 2014. The Compensation Committee operates under a written charter adopted by the Board, which is available in the "For Investors and Media—Corporate Governance" section of our website at www.t2biosystems.com.

    Nominating and Corporate Governance Committee.

        Josh Bilenker and John Cumming currently serve on the nominating and corporate governance committee, which is chaired by Josh Bilenker. Our Board of Directors has determined that each member of the nominating and corporate governance committee is "independent" as that term is defined in the applicable NASDAQ Stock Market rules. The nominating and corporate governance committee's responsibilities include:

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

    reviewing and making recommendations to the Board with respect to management succession planning;

    developing and recommending to the Board corporate governance guidelines; and

    overseeing an annual evaluation of the Board of Directors.

        The nominating and corporate governance committee operates pursuant to a written charter, which is available in the "For Investors and Media—Corporate Governance" section of our website at www.t2biosystems.com, and held its first meeting in 2014.

        The nominating and corporate governance committee considers candidates for Board membership suggested by its members and the Chief Executive Officer. Additionally, in selecting nominees for directors, the nominating and corporate governance committee will review candidates recommended by stockholders in the same manner and using the same general criteria as candidates recruited by the committee and/or recommended by the Board. Any stockholder who wishes to recommend a candidate for consideration by the committee as a nominee for director should follow the procedures described later in this proxy statement under the heading "Stockholder Matters—Stockholder Recommendations for Director Nominations." The Nominating Subcommittee will also consider whether to nominate any person proposed by a stockholder in accordance with the provisions of our bylaws relating to stockholder nominations as described later in this proxy statement under the heading "Stockholder Matters—Deadline for Stockholder Proposals and Director Nominations."

        Risk Oversight.    Our Board of Directors oversees the management of risks inherent in the operation of our business and the implementation of our business strategies. Our Board of Directors performs this oversight role by using several different levels of review. In connection with its reviews of the operations and corporate functions of our company, our Board of Directors addresses the primary risks associated with those operations and corporate functions. In addition, our Board of Directors reviews the risks associated with our company's business strategies periodically throughout the year as part of its consideration of undertaking any such business strategies.

16


Table of Contents

        Each of our Board committees also coordinates oversight of the management of our risk that falls within the committee's areas of responsibility. In performing this function, each committee has full access to management, as well as the ability to engage advisors. Our Chief Financial Officer reports to the audit committee and is responsible for identifying, evaluating and implementing risk management controls and methodologies to address any identified risks. In connection with its risk management role, our audit committee meets privately with representatives from our independent registered public accounting firm, and privately with our Chief Financial Officer.

    Technology Committee

        Michael Cima currently serves on the technology committee. The technology committee meets periodically to discuss scientific and technological developments that may affect our business.

        The technology committee held one meeting during 2014. The technology committee operates under a written charter adopted by the Board, which is available in the "For Investors and Media—Corporate Governance" section of our website at www.t2biosystems.com.

Audit Committee Report

        The information contained in this report shall not be deemed to be (1) "soliciting material," (2) "filed" with the SEC, (3) subject to Regulations 14A or 14C of the Exchange Act, or (4) subject to the liabilities of Section 18 of the Exchange Act. This report shall not be deemed incorporated by reference into any of our other filings under the Exchange Act or the Securities Act, except to the extent that we specifically incorporate it by reference into such filing.

        The audit committee operates under a written charter approved by the Board of Directors, which provides that its responsibilities include appointing, overseeing the independence of, and setting the compensation of our independent auditor, Ernst & Young LLP; pre-approving all audit services to be provided by the independent auditor; overseeing the work of the independent auditor, including through the receipt and consideration of reports from such firm; reviewing and discussing with management and our independent auditor our annual and quarterly financial statements and related disclosures; coordinating the Board's oversight of our internal control over financial reporting, disclosure controls and procedures and our code of conduct; discussing our risk management and risk assessment policies; establishing procedures for the receipt, retention and treatment of complaints regarding accounting, internal accounting controls or auditing matters; reviewing the company's policies and procedures for reviewing and approving or ratifying any related person transactions; and meeting independently with our internal auditing staff, if any, independent auditors and management.

        The audit committee assists the Board of Directors with the oversight of our financial reporting process. Management is responsible for our internal controls, financial reporting process, and compliance with laws and regulations and ethical business standards. Ernst & Young LLP is responsible for performing an independent audit of our consolidated financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). The audit committee's main responsibility is to monitor and oversee this process.

        The audit committee considered any fees paid to Ernst & Young LLP for the provision of non-audit related services and does not believe that these fees compromise Ernst & Young LLP's independence in performing the audit.

        Based on the review and discussions referred to above, the audit committee recommended to the Board of Directors that such audited financial statements be included in our Annual Report on Form 10-K for the year ended December 31, 2014, for filing with the SEC.

EXECUTIVE COMPENSATION

        This section discusses the material components of the executive compensation program offered to our named executive officers identified below. For 2014, our named executive officers were:

    John McDonough, President and Chief Executive Officer;

    Michael A. Pfaller, M.D., Chief Medical Officer; and

    Thomas J. Lowery, Ph.D., Chief Scientific Officer.


Overview

        Our compensation programs are designed to:

    attract and retain individuals with superior ability and managerial experience;

    align executive officers' incentives with our corporate strategies, business objectives and the long-term interests of our stockholders; and

    increase the incentive to achieve key strategic performance measures by linking incentive award opportunities to the achievement of performance objectives and by providing a portion of total compensation for executive officers in the form of ownership in the company.

        Our compensation committee is primarily responsible for establishing and approving, or recommending for approval by the Board of Directors, the compensation for all of our executive officers. The compensation committee oversees our compensation and benefit plans and policies, administers our equity incentive plans and reviews and approves, or recommends for approval by the Board of Directors, annually all compensation decisions relating to all of our executive officers, including our chief executive officer. The compensation committee considers recommendations from our chief executive officer regarding the compensation of our executive officers other than himself. Our compensation committee has the authority under its charter to engage the services of a consulting firm or other outside advisor to assist it in designing our compensation programs and in making compensation decisions and has engaged Arnosti Consulting to provide these services.


Executive Compensation Components

        Our executive compensation consists of base salary, cash incentive bonuses, long-term incentive compensation in the form of stock options, and a broad-based benefits program. We have not adopted any formal guidelines for allocating total compensation between long-term and short-term compensation, cash compensation and non-cash compensation, or among different forms of non-cash compensation. The compensation committee considers a number of factors in setting compensation for its executive officers, including Company performance, as well as the executive's performance, experience, responsibilities and the compensation of executive officers in similar positions at comparable companies.

Base Salary

        Our named executive officers receive base salary to compensate them for the satisfactory performance of duties to our company. The base salary payable to each named executive officer is intended to provide a fixed component of compensation reflecting the executive's skill set, experience, role and responsibilities. Base salaries for our named executive officers have generally been set at levels deemed necessary to attract and retain individuals with superior talent. Dr. Pfaller's base salary for 2014 was originally negotiated in connection with his commencing employment with us during 2014.

        In July 2014, our Board of Directors approved, effective upon the closing of the initial public offering of our common stock, an increase in Mr. McDonough's base salary to $425,000, Dr. Pfaller's base salary to $325,000 and Dr. Lowery's base salary to $325,000.

Cash Incentive Compensation

        Each of our named executive officers is eligible to participate in an annual cash incentive compensation program which provides participants with an opportunity to earn variable cash incentive compensation based on individual and company performance. In July 2014, our Board of Directors approved, effective upon the closing of the initial public offering of our common stock, an increase in the target annual variable cash incentive compensation levels for each of our named executive officers. Following the increase, the target level for 2014 for Mr. McDonough was 50% of his annual base salary and the target levels for Dr. Pfaller and Dr. Lowery were 40% of their respective base salaries.

        Objectives for the 2014 annual cash incentive compensation program were established in January 2014 by our compensation committee and generally related to attaining clinical, business development and financing milestones and publication, commercialization and operational goals.

        The annual variable cash incentive compensation earned by our named executive officers for 2014 are set forth in the "Non-Equity Incentive Plan Compensation" column of our 2014 Summary Compensation Table. Variable cash incentive amounts were approved in early 2015 by our compensation committee for Drs. Pfaller and Lowery and by our Board of Directors based upon the recommendation of our compensation committee for Mr. McDonough.

Equity-Based Compensation

        We generally offer stock options to our employees, including our named executive officers, as the long-term incentive component of our compensation program. We typically grant options to employees when they commence employment with us and may thereafter grant additional options in the discretion of our Board of Directors. Our stock options typically vest as to 25% of the shares subject to the option on the first anniversary of the date of grant and in equal monthly installments over the ensuing 36 months, subject to the holder's continued employment with us. From time to time, our Board of Directors may also construct alternate vesting schedules as it determines are appropriate to motivate particular employees.

        We awarded stock options to our named executive officers in 2014 in the following amounts:

        These options were granted with exercise prices equal to the fair market, as determined by our Board of Directors, of our common stock on the date of grant. The options granted to Mr. McDonough and Dr. Lowery vest in 48 equal monthly installments following the date of grant. The

options granted to Dr. Pfaller vest as to 25% of the shares subject to the option on the first anniversary of the date of grant, and in equal monthly installments over the ensuing 36 months.

Retirement, Health, Welfare and Additional Benefits

        Our named executive officers are eligible to participate in our employee benefit plans and programs, including medical and dental benefits, flexible spending accounts and short-and long-term disability and life insurance, to the same extent as our other full-time employees, subject to the terms and eligibility requirements of those plans. Our named executive officers are also eligible to participate in a tax-qualified 401(k) defined contribution plan to the same extent as all of our other full-time employees. Currently, we do not match contributions made by participants in the 401(k) plan or make other contributions to participant accounts.

All unvested options for Mr. McDonough and Dr. Lowery vest in equal monthly installments over the 48 month vesting period, subject to the holder's continued employment with us through the applicable vesting date and potential accelerated vesting as described in the sections titled "Employment Letter Agreements with Our Named Executive Officers" and "Potential Payments upon a Change in Control" below.

Employment Letter Agreements with Our Named Executive Officers

        We have entered into an employment letter agreement with each of the named executive officers. Certain key terms of these agreements are described below.

        John McDonough.    In 2008 we entered into an employment letter agreement with Mr. McDonough. This agreement entitled Mr. McDonough to receive an initial annual base salary of $300,000, subject to periodic increases at the discretion of the Board of Directors, and annual variable cash incentive compensation opportunity of not less than $75,000, with the amount of any such variable cash incentive compensation based primarily on the overall performance of our company, measured against goals that are mutually agreed between Mr. McDonough and our compensation committee early in each applicable year. The employment letter agreement provides that, if Mr. McDonough is terminated by us without cause, he will be entitled to receive 6 months of base salary continuation and a lump-sum payment in an amount equal to 50% of the maximum amount of his annual variable cash incentive compensation for the year of termination. In July 2014, Mr. McDonough's employment letter

21


Table of Contents

agreement was amended, effective upon the closing of our initial public offering, to provide that if Mr. McDonough's employment is terminated by us without cause within the three months preceding or the 12 months following a change in control, or if Mr. McDonough resigns his employment for good reason within the 12 months following a change in control, and he timely executes a release of claims in our favor, he will be entitled to receive 18 months of base salary continuation, a lump-sum payment in an amount equal to his target annual variable cash incentive compensation for the year of termination, accelerated vesting of all outstanding unvested equity awards and reimbursement for a portion (based on cost sharing for active employees) of health care continuation premiums for up to 18 months. The new amendment also increased Mr. McDonough's base salary to $425,000 and his target variable cash incentive compensation level to 50% of his annual base salary.

        Mr. McDonough's employment letter agreement, as amended, also contains restrictive covenants pursuant to which he has agreed to refrain from competing with us or soliciting our customers, prospective customers, employees or consultants for one year following his termination of employment.

        Michael Pfaller, M.D.    In February 2014, we entered into an employment letter agreement with Dr. Pfaller. This agreement entitled him to an initial annual base salary of $200,000 and annual variable cash incentive compensation up to 15% of his annual base salary. In July 2014, we entered into a new agreement with Dr. Pfaller, effective upon the closing of our initial public offering, which provides that if Dr. Pfaller's employment is terminated by us without cause within the three months preceding or the 12 months following a change in control, or if Dr. Pfaller resigns his employment for good reason within the 12 months following a change in control, and he timely executes a release of claims in our favor, he will be entitled to receive 12 months of base salary continuation, accelerated vesting of all outstanding unvested equity awards and reimbursement for a portion (based on active employee cost sharing rates) of health care premiums for up to 12 months. The new agreement also increased Dr. Pfaller's base salary to $325,000 and his target variable cash incentive compensation level to 40% of his annual base salary.

        Dr. Pfaller has also entered into a non-compete, non-disclosure and invention assignment agreement with us pursuant to which he has agreed to refrain from disclosing our confidential information indefinitely and from competing with us or soliciting our employees or consultants for 12 months following termination of his employment.

        Thomas J. Lowery, PhD.    In 2006 we entered into employment letter agreement with Dr. Lowery. This agreement entitled him to an initial annual base salary of $87,000 and annual variable cash incentive compensation up to $5,000. In July 2014, we entered into a new agreement with Dr. Lowery, effective upon the closing of our initial public offering, which provides that if Dr. Lowery's employment is terminated by us without cause within the three months preceding or the 12 months following a change in control, or if Dr. Lowery resigns his employment for good reason within the 12 months following a change in control, and he timely executes a release of claims in our favor, he will be entitled to receive 12 months of base salary continuation, accelerated vesting of all outstanding unvested equity awards and reimbursement for a portion (based on active employee cost sharing rates) of health care premiums for up to 12 months. The new agreement also increased Dr. Lowery's base salary to $325,000 and his target variable cash incentive compensation level to 40% of his annual base salary.

        Dr. Lowery has also entered into a non-compete, non-disclosure and invention assignment agreement with us pursuant to which he has agreed to refrain from disclosing our confidential information indefinitely and from competing with us or soliciting our employees or consultants for 12 months following termination of his employment.

Potential Payments Upon a Change in Control

        As described above, under the terms of their employment letter agreements, Mr. McDonough, Dr. Pfaller and Dr. Lowery may become entitled to payments or benefits in connection with certain terminations of employment that occur at specified times around a change in control.

        The agreements governing our named executive officers' unvested stock options provide for full accelerated vesting if their employment is terminated without cause within the three months preceding or the 12 months following a change of control or if they resign for good reason within 12 months following a change in control.
