PROXY STATEMENT

FOR THE 2020 ANNUAL MEETING OF STOCKHOLDERS

To Be Held On June 25, 2020

QUESTIONS AND ANSWERS ABOUT THESE PROXY MATERIALS AND VOTING

Our Board of Directors (sometimes referred to as the "Board") is soliciting your proxy to vote at the 2020 annual meeting of stockholders (the "Annual Meeting") of Cidara Therapeutics, Inc., a Delaware corporation (sometimes referred to as "we," "us," the "Company" or "Cidara") to be held virtually, via live webcast at www.virtualshareholdermeeting.com/CDTX2020, on Thursday, June 25, 2020, at 8:00 a.m. Pacific Time, and any adjournment or postponement thereof. We are committed to ensuring that our stockholders attending the virtual meeting will be afforded the same rights and opportunities to participate as they would at an in-person meeting.

For the Annual Meeting, we have elected to furnish our proxy materials, including this proxy statement and our Annual Report on Form 10-K for the fiscal year ended December 31, 2019 (the "Annual Report"), to our stockholders primarily via the internet. On or about May 7, 2020, we expect to mail to our stockholders a Notice of Internet Availability of Proxy Materials (the "Notice") that contains notice of the Annual Meeting and instructions on how to access our proxy materials on the internet, how to vote at the Annual Meeting, and how to request printed copies of the proxy materials. That notice also contains instructions on how you can receive a paper copy of this proxy statement and Annual Report or an electronic copy via e-mail if you prefer either of those alternatives.

Only stockholders of record of our common stock at the close of business on April 27, 2020 (the "Record Date") will be entitled to vote at the Annual Meeting. On the Record Date, there were 40,736,530 shares of common stock outstanding and entitled to vote (together, the "common stock"). A list of stockholders entitled to vote at the Annual Meeting will be available for examination during normal business hours for ten days before the Annual Meeting at our address above. The stockholder list will also be available online during the Annual Meeting.

Why did I receive a notice regarding the availability of proxy materials on the internet?

Pursuant to rules adopted by the SEC, we have elected to provide access to our proxy materials over the internet. Accordingly, we have sent you a Notice of Internet Availability of Proxy Materials (the "Notice") because the Board of Cidara is soliciting your proxy to vote at the 2020 Annual Meeting, including at any adjournments or postponements of the Annual Meeting.

Stockholder of Record: Shares Registered in Your Name

If, on April 27, 2020 , your shares were registered directly in your name with Cidara's transfer agent, American Stock Transfer & Trust Company, LLC, then you are a stockholder of record. As a stockholder of record, you may vote by virtual attendance at the Annual Meeting or vote by proxy. Whether or not you plan to attend the Annual Meeting, we urge you to fill out and return the proxy card that may be mailed to you, or vote by proxy over the telephone or on the internet as instructed below to ensure your vote is counted.

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

If, on April 27, 2020 , your shares were held, not in your name, but rather in an account at a brokerage firm, bank, dealer or other similar organization, then you are the beneficial owner of shares held in "street name" and the 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 or other agent regarding how to vote the shares in your account. You are also invited to attend the Annual Meeting. However, since you are not the stockholder of record, you may not vote your shares by virtual attendance at the Annual Meeting unless you request and obtain a valid proxy from your broker or other agent.

What am I voting on?

There are two matters scheduled for a vote:

  • Proposal 1: Election of the two nominees for Class II director named herein to hold office until the 2023 Annual Meeting of Stockholders; and
  • Proposal 2: Ratification of the selection of Ernst & Young LLP by the Audit Committee of the Board to serve as the independent registered public accounting firm of the Company for the fiscal year ending December 31, 2020 .

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

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

How do I vote?

You may either vote "For" all the nominees to the Board or you may "Withhold" your vote for any nominee you specify. For each of the other matters to be voted on, you may vote "For" or "Against" or abstain from voting.

The procedures for voting are as follows:

Stockholder of Record: Shares Registered in Your Name

If you are a stockholder of record, you may vote by virtual attendance 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

3

time. Whether or not you plan to attend the Annual Meeting, we urge you to vote by proxy to ensure your vote is counted. You may still attend the Annual Meeting and vote online during the Annual Meeting even if you have already voted by proxy.

  • VOTE DURING MEETING: To vote online during the Annual Meeting, follow the provided instructions to join the Annual Meeting at www.virtualshareholdermeeting.com/CDTX2020, starting at 8:00 a.m. Pacific Time on Thursday, June 25, 2020.
  • VOTE BY PHONE: To vote over the telephone, dial toll-free1-800-690-6903 using any touch-tone telephone and follow the recorded instructions. You will be asked to provide the control number from the Notice. Your telephone vote must be received by 11:59 p.m. Eastern Time on Wednesday, June 24, 2020 to be counted.
  • VOTE BY INTERNET: To vote over the internet, complete an electronic proxy card at www.proxyvote.com. You will be asked to provide the control number from the Notice. Your internet vote must be received by 11:59 p.m. Eastern Time on Wednesday, June 24, 2020 to be counted.
  • VOTE BY PROXY CARD: To vote using a proxy card, simply complete, sign and date the proxy card that may be delivered to you and return it promptly in the envelope we have provided or return it to Proxy Tabulator for Cidara Therapeutics, Inc., Vote Processing, c/o Broadridge, 51 Mercedes Way, Edgewood, NY 11717. If you return your signed proxy card to us before the Annual Meeting, we will vote your shares as you direct.

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 brokerage firm, bank, dealer or other agent, you should have received the

Notice containing voting instructions from that organization rather than from Cidara. Simply follow the voting instructions in the Notice to ensure that your vote is counted. Alternatively, you may vote by telephone or over the internet as instructed by your broker or bank. To vote online during at the Annual Meeting, you must obtain a valid proxy from your brokerage firm, bank, dealer or other agent. Follow the instructions from your broker or bank, or contact your broker or bank to request a proxy form.

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

Can I vote my shares by filling out and returning the Notice?

No. The Notice identifies the items to be voted on at the Annual Meeting, but you cannot vote by marking the Notice and returning it. The Notice provides instructions on how to vote through the internet, by telephone, by using a printed proxy card or by submitting a ballot online during the Annual Meeting.

How many votes do I have?

On each matter to be voted upon, you have one vote for each share of common stock you own as of the close of business on April 27, 2020 .

What happens if I do not vote?

Stockholder of Record: Shares Registered in Your Name

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

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

If you are a beneficial owner and do not instruct your brokerage firm, bank, dealer or other agent how to vote your shares, the question of whether your broker or nominee will still be able to vote your shares depends on whether the particular proposal is

4

considered to be a routine matter under applicable rules. Brokers and nominees can use their discretion to vote uninstructed shares with respect to matters that are considered to be routine under applicable rules, but not with respect to non-routine matters. Under applicable rules and interpretations, non-routine matters are matters that may substantially affect the rights or privileges of stockholders, such as mergers, stockholder proposals, elections of directors (even if not contested), executive compensation (including any advisory stockholder votes on executive compensation and on the frequency of stockholder votes on executive compensation), and certain corporate governance proposals, even if management-supported. Accordingly, without your instructions your broker or nominee may not vote your shares on Proposal 1, but may vote your shares on Proposal 2.

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 mustprovide 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.

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

If you return a signed and dated proxy card or otherwise vote without marking voting selections, your shares will be voted, as applicable, "For" the election of both nominees for director and "For" the ratification of the selection of Ernst & Young LLP by the Audit Committee of the Board to serve as the independent registered public accounting firm of the Company for the fiscal year ending December 31, 2020 . If any other matter is properly presented at the meeting, your proxy holder (one of the individuals named on your proxy card) will vote your shares using his or her best judgment.

Who is paying for this proxy solicitation?

Cidara will pay for the entire cost of soliciting proxies, including preparing, assembling, making available on the internet and printing and mailing this proxy statement, the proxy card and any additional information furnished to stockholders. In addition to these proxy materials, Cidara's directors and employees may also solicit proxies in person, by telephone, electronic mail, or by other means of communication. Directors and employees will not be paid any additional compensation for soliciting proxies. We may also reimburse brokerage firms, banks, dealers or other agents for the cost of forwarding proxy materials to beneficial owners. However, please be aware that you must bear any costs associated with your internet service, such as usage charges from internet access providers or telephone companies.

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

If you receive more than one Notice, your shares may be registered in more than one name or in different accounts. Please follow the voting instructions on each Notice to ensure that all 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 Cidara's Secretary at 6310 Nancy Ridge Drive, Suite 101, San Diego, CA 92121.
  • You may vote during the Annual Meeting which will be hosted via the internet. Simply attending the virtual meeting will not, by itself, revoke your proxy. Even if you plan to virtually attend the Annual Meeting, we recommend that you also submit your proxy or voting instructions or vote by telephone or by completing an electronic proxy card at www.proxyvote.comso that your vote will be counted if you later decide not to virtually attend the Annual Meeting.

Your most recent proxy card or telephone or internet proxy is the one that is counted.

5

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

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

When are stockholder proposals and director nominations due for next year's annual meeting?

To be considered for inclusion in the Company's proxy materials for next year's annual meeting, your proposal must be submitted in writing by January 7, 2021 , to the attention of the Secretary of Cidara Therapeutics, Inc., 6310 Nancy Ridge Drive, Suite 101, San Diego, CA 92121. If you wish to submit a proposal (including a director nomination) that is not to be included in the Company's proxy materials for next year's annual meeting, you must do so between February 25, 2021 and March 27, 2021 . You are also advised to review the Company's Bylaws, which contain additional requirements relating to advance notice of stockholder proposals and director nominations.

What are "broker non-votes"?

When a beneficial owner of shares held in "street name" does not give instructions to the brokerage firm, bank, dealer or other agent holding the shares as to how to vote on matters deemed to be non-routine under applicable rules, the broker or nominee cannot vote the shares. These unvoted shares are counted as "broker non-votes."

How are votes counted?

Votes will be counted by the inspector of election appointed for the virtual Annual Meeting, who will separately count, for the proposal to elect directors, votes "For," "Withhold" and broker non-votes; and, for the proposal to ratify the Audit Committee's selection of Ernst & Young LLP as our independent public accounting firm, votes "For" and "Against," and abstentions. Abstentions will be counted towards the vote total for Proposal 2 and will have the same effect as "Against" votes. Broker non-votes will be counted towards the presence of a quorum but will not be counted towards the vote total for any proposal.

How many votes are needed to approve each proposal?

  • For Proposal 1, the election of directors, the two nominees receiving the most "For" votes from the holders of shares present online or represented by proxy and entitled to vote on the election of directors will be elected. Only votes "For" or "Withheld" will affect the outcome.
  • To be approved, Proposal 2, the ratification of the selection of Ernst & Young LLP as the Company's independent registered public accounting firm for its fiscal year ending December 31, 2020 , must receive "For" votes from the holders of a majority of shares present online 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. Broker non-votes, if any, will have no effect.

What is the quorum requirement?

A quorum of stockholders is necessary to hold the virtual Annual Meeting. A quorum will be present if stockholders holding at least a majority of the outstanding shares entitled to vote are present by virtual attendance at the Annual Meeting or represented by proxy. On the record date, there were 40,736,530 shares outstanding and entitled to vote. Thus, the holders of 20,368,265 shares must be present by virtual attendance or represented by proxy at the Annual Meeting to have a quorum.

Your shares will be counted towards the quorum only if you submit a valid proxy (or one is submitted on your behalf by your brokerage firm, bank, dealer or other agent) or if you vote online during 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 by virtual attendance at the Annual Meeting or represented by proxy may adjourn the Annual Meeting to another date.

6

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

Preliminary voting results will be announced at the Annual Meeting. In addition, final voting results will be published in a current report on Form 8- K that we expect to file with the SEC within four business days after 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 Annual Meeting, we intend to file a Form 8-K to publish preliminary results and, within four business days after the final results are known to us, file an additional Form 8-K to publish the final results.

PROPOSAL 1

ELECTION OF DIRECTORS

The Board is divided into three classes. 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 presently has six members. There are two Class II directors whose term of office expires in 2020 : Daniel Burgess and Theodore R. Schroeder.

Messrs. Burgess and Schroeder have been nominated for reelection at the Annual Meeting. Proxies may not be voted for a greater number of persons than the number of nominees named in this proxy statement. Messrs. Burgess and Schroeder were recommended for nomination to the Board at the Annual Meeting by the Nominating and Corporate Governance Committee of the Board. If elected at the Annual Meeting, each of these nominees would serve until the 2023 annual meeting of stockholders and until his successor has been duly elected and qualified, or, if sooner, until his death, resignation or removal. It is the Company's policy to invite directors and nominees for director to attend the Annual Meeting. Five of the Company's then-serving directors attended the 2019 Annual Meeting of Stockholders.

Directors are elected by a plurality of the votes of the holders of shares present by virtual attendance 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. Shares represented by executed proxies will be voted, if authority to do so is not withheld, for the election of Messrs. Burgess and Schroeder. If any nominee becomes unavailable for election as a result of an unexpected occurrence, shares that would have been voted for that nominee will instead be voted for the election of a substitute nominee proposed by the Company. Each of Messrs. Burgess and Schroeder has agreed to serve if elected. The Company's management has no reason to believe that any nominee will be unable to serve.

NOMINEES

The Nominating and Corporate Governance Committee seeks to assemble a Board that, as a whole, possesses the appropriate balance of professional and industry knowledge, financial expertise and high-level management experience necessary to oversee and direct the Company's business. To that end, the Nominating and Corporate Governance Committee has identified and evaluated nominees in the broader context of the Board's overall composition, with the goal of recruiting members who complement and strengthen the skills of other members and who also exhibit integrity, collegiality, sound business judgment and other qualities that the Nominating and Corporate Governance Committee views as critical to effective functioning of the Board. The brief biographies below include information, as of the date of this proxy statement, regarding the specific and particular experience, qualifications, attributes or skills of each director or nominee that led the Nominating and Corporate Governance Committee to believe that that nominee should continue to serve on the Board. However, each of the members of the Nominating and Corporate Governance Committee may have a variety of reasons why he believes a particular person would be an appropriate nominee for the Board, and these views may differ from the views of other members.

INFORMATION REGARDING THE BOARD OF DIRECTORS AND CORPORATE GOVERNANCE

INDEPENDENCE OF THE BOARD OF DIRECTORS

As required under the Nasdaq Stock Market ("Nasdaq") listing standards, a majority of the members of a listed company's board of directors must qualify as "independent," as affirmatively determined by the board of directors. Our Board 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, as in effect from time to time.

Consistent with these considerations, after review of all relevant identified transactions or relationships between each director, or any of his or her family members, and the Company, its senior management and its independent auditors, the Board has affirmatively determined that all of our directors, except Dr. Stein who is not considered independent because he is an executive officer of the Company, are independent directors as defined by

Rule 5605(a)(2) of the Nasdaq Listing Rules. In making this determination, the Board found that none of these directors had a material or other disqualifying relationship with the Company.

BOARD LEADERSHIP STRUCTURE

Daniel Burgess, currently serves as the Chairman of our Board, and has authority, among other things, to call and preside over Board meetings, to set meeting agendas and to determine materials to be distributed to the Board. Accordingly, the Chairman has substantial ability to shape the work of the Board. We believe that separation of the positions of Chairman and Chief Executive Officer reinforces the independence of the Board in its oversight of our business and affairs. In addition, we have a separate chair for each committee of the Board. The chair of each committee is expected to report to the Board from time to time, or whenever so requested by the Board, on the activities of his or her committee in fulfilling its responsibilities as detailed in its respective charter or specify any shortcomings should that be the case. In addition, we believe that having a separate Chairman creates an environment that is more conducive to objective evaluation and oversight of management's performance, increasing management accountability and improving the ability of the Board to monitor whether management's actions are in the best interests of us and our stockholders. As a result, we believe that having a separate Chairman can enhance the effectiveness of the Board as a whole.

ROLE OF THE BOARD IN RISK OVERSIGHT

One of the key functions of our Board is informed oversight of our risk management process. Our 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 standing committees of our Board that address risks inherent in their respective areas of oversight. In particular, our Board is responsible for monitoring and assessing strategic risk exposure, and our 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 compliance with legal and regulatory requirements. Our Nominating and Corporate Governance Committee monitors the effectiveness of our corporate governance practices, including whether they are successful in preventing illegal or improper liability-creating conduct. Our Compensation Committee assesses and monitors whether any of our compensation policies and programs has the potential to encourage excessive risk-taking.

MEETINGS OF THE BOARD OF DIRECTORS

The Board met six times and acted by unanimous written consent seven times during 2019 . All directors attended at least 75% of the aggregate number of meetings of the Board and of the committees on which they served during 2019 .

In fiscal year 2019 , the Company's independent directors met four times in an executive session at which only independent directors were present.

Below is a description of each committee of the Board. Each of the committees has authority to engage legal counsel or other experts or consultants, as it deems appropriate to carry out its responsibilities. The Board has determined that each member of each committee meets the applicable rules and regulations regarding "independence" and that each member is free of any relationship that would impair his or her individual exercise of independent judgment with regard to the Company.

Audit Committee

The Audit Committee of the Board was established by the Board in accordance with Section 3(a)(58)(A) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), to oversee the Company's corporate accounting and financial reporting processes and audits of its financial statements. For this purpose, the Audit Committee performs several functions, including, among other things:

  • evaluating the performance, independence and qualifications of our independent auditors and determining whether to retain our existing independent auditors or engage new independent auditors;
  • reviewing and approving the engagement of our independent auditors to perform audit services and any permissible non-audit services;
  • monitoring the rotation of partners of our independent auditors on our engagement team as required by law;
  • prior to engagement of any independent auditor, and at least annually thereafter, reviewing relationships that may reasonably be thought to bear on their independence, and assessing and otherwise taking the appropriate action to oversee the independence of our independent auditor;
  • reviewing our annual and quarterly financial statements and reports, including the disclosures contained under the caption "Management's Discussion and Analysis of Financial Condition and Results of Operations," and discussing the statements and reports with our independent auditors and management;
  • reviewing, with our independent auditors and management, significant issues that arise regarding accounting principles and financial statement presentation and matters concerning the scope, adequacy and effectiveness of our financial controls;
  • reviewing with management and our independent auditors any earnings announcements and other public announcements regarding material developments;
  • establishing procedures for the receipt, retention and treatment of complaints received by us regarding financial controls, accounting or auditing matters and other matters;
  • preparing the report that the SEC requires in our annual proxy statement;

12

  • reviewing and providing oversight of any related-party transactions in accordance with our related-party transaction policy and reviewing and monitoring compliance with legal and regulatory responsibilities, including our code of business conduct and ethics;
  • reviewing our major financial risk exposures, including the guidelines and policies to govern the process by which risk assessment and risk management are implemented;
  • reviewing, on a periodic basis, our investment policy; and
  • reviewing and evaluating, on an annual basis, the performance of the Audit Committee and the Audit Committee charter.

The Audit Committee is currently composed of three directors: Messrs. Burgess (Chair) and Schroeder and Ms. Mineo. The Board has adopted a written Audit Committee charter that is available to stockholders on the Company's website at www.cidara.com. The information on our website is not incorporated by reference into this proxy statement or our Annual Report for fiscal year 2019 .

The Board reviews the Nasdaq listing standards definition of independence for Audit Committee members on an annual basis and has determined that all members of the Company's Audit Committee are independent (as independence is currently defined in the applicable Nasdaq listing standards and Rule 10A-3 of the Exchange Act).

The Board has also determined that Mr. Burgess qualifies as an "audit committee financial expert," as defined in applicable SEC rules. The Board made a qualitative assessment of Mr. Burgess' level of knowledge and experience based on a number of factors, including his formal education and previous and current experience in financial roles.

Report of the Audit Committee of the Board of Directors*

The Audit Committee has reviewed and discussed the audited financial statements for the fiscal year ended December 31, 2019 with management of the Company. The Audit Committee has discussed with the independent registered public accounting firm the matters required to be discussed by Auditing Standard No. 1301, Communications with Audit Committees, as adopted by the Public Company Accounting Oversight Board ("PCAOB"). The Audit Committee has also received the written disclosures and the letter from the independent registered public accounting firm required by applicable requirements of the PCAOB regarding the accountants' communications with the Audit Committee concerning independence and has discussed with the independent registered public accounting firm the accounting firm's independence. Based on the foregoing, the Audit Committee has recommended to the Board of Directors that the audited financial statements be included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2019 .

Compensation Committee

The Compensation Committee of the Board is currently composed of three directors: Mr. Schroeder (Chair), Dr. Franson and Ms. Mineo. Our Board has determined that each of the members of our Compensation Committee is a non-employee director, as defined in Rule 16b-3 promulgated under the Exchange Act and satisfies the Nasdaq independence requirements.

13

The Compensation Committee acts on behalf of the Board to review, adopt or recommend to the Board for adoption, and oversee the Company's compensation strategy, policies, plans and programs. For this purpose, the Compensation Committee performs several functions, including, among other things:

  • reviewing, modifying and approving (or if it deems appropriate, making recommendations to the full Board regarding) our overall compensation strategy and policies;
  • making recommendations to the full Board regarding the compensation and other terms of employment of our Chief Executive Officer;
  • reviewing, modifying and approving (or if it deems appropriate, making recommendations to the full Board regarding) the compensation and other terms of employment of our other executive officers;
  • reviewing and making recommendations to the full Board regarding performance goals and objectives relevant to the compensation of our executive officers and assessing their performance against these goals and objectives;
  • reviewing and approving (or if it deems it appropriate, making recommendations to the full Board regarding) the equity incentive plans, compensation plans and similar programs advisable for us, as well as modifying, amending or terminating existing plans and programs;
  • evaluating risks associated with our compensation policies and practices and assessing whether risks arising from our compensation policies and practices for our employees are reasonably likely to have a material adverse effect on us;
  • reviewing and making recommendations to the full Board regarding the type and amount of compensation to be paid or awarded to our non- employee board members;
  • establishing policies with respect to votes by our stockholders to approve executive compensation to the extent required by Section 14A of the Exchange Act and, if applicable, determining our recommendations regarding the frequency of advisory votes on executive compensation;
  • reviewing and assessing the independence of compensation consultants, legal counsel and other advisers as required by Section 10C of the Exchange Act;
  • administering our equity incentive plans;
  • establishing policies with respect to equity compensation arrangements;
  • reviewing the competitiveness of our executive compensation programs and evaluating the effectiveness of our compensation policy and strategy in achieving expected benefits to us;
  • reviewing with management and approving our disclosures under the caption "Compensation Discussion and Analysis" in our periodic reports or proxy statements to be filed with the SEC, to the extent such caption is included in any such report or proxy statement;
  • preparing the report that the SEC requires in our annual proxy statement; and
  • reviewing and evaluating, on an annual basis, the performance of the Compensation Committee and the Compensation Committee charter.

Compensation Committee Processes and Procedures

Typically, the Compensation Committee meets at least 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 management. 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 does not participate in, and is not 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 its charter, the Compensation Committee has the authority to

14

obtain, at the expense of the Company, advice and assistance from internal and external legal, accounting or other advisers 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 advisers engaged for the purpose of advising the Compensation Committee. In particular, the Compensation Committee has the sole authority to retain compensation consultants to assist in its evaluation of executive and director compensation, including the authority to approve the consultant's reasonable fees and other retention terms. Under its charter, to the extent required by SEC and Nasdaq rules, 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.

In 2019 , the Company engaged Radford, a business unit of Aon plc ("Radford"), as its compensation consultant. Radford was retained to provide an assessment of the Company's executive and director compensation programs in comparison to executive and director compensation programs at selected publicly-traded peer companies. As part of its engagement, Radford was requested by the Compensation Committee to develop the peer group of comparative companies and to perform analyses of compensation levels for that group. Radford developed peer group and related recommendations that were presented to the Compensation Committee for its consideration.

The Compensation Committee holds one or more meetings during the first quarter of the year to discuss and make recommendations to the Board for annual compensation adjustments, annual bonuses, annual equity awards, and new corporate performance objectives . However, the Compensation Committee also considers matters related to individual compensation, such as compensation for new executive hires, as well as high-level strategic issues, such as the effectiveness of the Company's compensation strategy, potential modifications to that strategy and new trends, plans or approaches to compensation, at periodic meetings throughout the year on an as-needed basis. Generally, the Compensation Committee's process comprises two related elements: the determination of compensation levels and the establishment of performance objectives for the current year. For executives other than the Chief Executive Officer, the Compensation Committee solicits and considers evaluations and recommendations submitted to the Compensation Committee by the Chief Executive Officer. In the case of the Chief Executive Officer, the evaluation of his performance is conducted by the Compensation Committee, which determines recommendations to the Board regarding any adjustments to his compensation as well as awards to be granted. 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, executive stock ownership information, company stock performance data, analyses of historical executive compensation levels and current Company-wide compensation levels, compensation data from comparative companies, compensation surveys, and recommendations of any compensation consultant, if applicable .

Nominating and Corporate Governance Committee

The Nominating and Corporate Governance Committee of the Board is responsible for identifying, reviewing and evaluating candidates to serve as directors of the Company (consistent with criteria approved by the Board), reviewing and evaluating incumbent directors, selecting or recommending to the Board for selection candidates for election to the Board, making recommendations to the Board regarding the membership of the committees of the Board, assessing the performance of the Board, and developing a set of corporate governance principles for the Company.

The Nominating and Corporate Governance Committee is currently composed of three directors: Drs. Franson (Chair) and Gollaher and Mr. Burgess. All members of the Nominating and Corporate Governance Committee are independent (as independence is currently defined under applicable Nasdaq listing standards ). The Board has adopted a written Nominating and Corporate Governance Committee charter that is available to stockholders on the Company's website and www.cidara.com. The information on our website is not incorporated by reference into this Proxy Statement or our Annual Report for fiscal year 2019 . The functions of this committee include, among other things:

  • identifying, reviewing and evaluating candidates to serve on our Board;
  • determining the minimum qualifications for service on our Board;

15

  • evaluating director performance on the Board and applicable committees of the Board and determining whether continued service on our Board is appropriate;
  • nominating and recommending individuals for membership on our Board;
  • evaluating nominations by stockholders of candidates for election to our Board;
  • considering and assessing the independence of members of our Board;
  • developing a set of corporate governance policies and principles and recommending to our Board any changes to such policies and principles;
  • considering questions of possible conflicts of interest of directors as such questions arise; and
  • reviewing and evaluating on an annual basis the performance of the Nominating and Corporate Governance Committee and the Nominating and Corporate Governance Committee charter.

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 and possessing the highest personal integrity and ethics. The Nominating and Corporate Governance Committee also considers 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, applicable laws (such as California's board gender diversity law) and the long-term interests of stockholders. In conducting this assessment, the Nominating and Corporate Governance Committee typically considers diversity, age, skills and such other factors as it deems appropriate, given the current needs of the Board and the Company, to maintain a balance of knowledge, experience and capability. In the case of incumbent directors whose terms of office are set to expire, the Nominating and Corporate Governance 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. 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 selects candidates 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: c/o Cidara Therapeutics, Inc., 6310 Nancy Ridge Drive, Suite 101, San Diego, CA 92121, Attn: Secretary, no later than the close of business on the 90 th day nor earlier than the close of business on the 120 th day prior to the first anniversary of the preceding year's annual meeting. Submissions must include the name and address of the Company stockholder on whose behalf the submission is made; the number of Company shares that are owned beneficially by such stockholder as of the date of the submission; the full name of the proposed candidate; a description of the proposed candidate's business experience for at least the previous five years; complete biographical information for the proposed candidate; and a description of the proposed candidate's qualifications as a director. 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.

16

STOCKHOLDER COMMUNICATIONS WITH THE BOARD OF DIRECTORS

The Company's Board has adopted a formal process by which stockholders may communicate with the Board or any of its directors. Stockholders who wish to communicate with the Board may do so by sending written communications addressed to the Secretary of Cidara Therapeutics, Inc., 6310 Nancy Ridge Drive, Suite 101, San Diego, CA 92121. These communications will be reviewed by the Secretary of Cidara, who will determine whether the communication is appropriate for presentation to the Board or the relevant director. The purpose of this screening is to allow the Board to avoid having to consider irrelevant or inappropriate communications (such as advertisements, solicitations and hostile communications).

CODE OF ETHICS

The Company has adopted a Code of Business Conduct and Ethics that applies to all officers, directors and employees. The Code of Business Conduct and Ethics is available on the Company's website at www.cidara.com. If the Company makes any substantive amendments to the Code of Business Conduct and Ethics or grants any waiver from a provision of the code to any executive officer or director, the Company will promptly disclose the nature of the amendment or waiver on its website. The information on our website is not incorporated by reference into this proxy statement or our Annual Report.

HEDGING POLICY

All employees, including our named executive officers, and non-employee directors are prohibited from engaging in short sales of our securities, establishing margin accounts, pledging our securities as collateral for a loan, buying or selling puts or calls on our securities or otherwise engaging in hedging transactions that offset any decrease in the market value involving our securities held by such persons (such as zero-cost dollars, exchange funds, and forward sale contracts).

PROPOSAL 2

RATIFICATION OF SELECTION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee has selected Ernst & Young LLP ("Ernst & Young") as the Company's independent registered public accounting firm for the fiscal year ending December 31, 2020 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. Ernst & Young has audited the Company's financial statements since 2013. Representatives of Ernst & Young are expected to be present at the Annual Meeting. They will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions.

Neither the Company's Bylaws nor other governing documents or law require stockholder ratification of the selection of Ernst & Young as the Company's independent registered public accounting firm. However, the Audit Committee is submitting the selection of Ernst & Young to the stockholders for ratification as a matter of good corporate practice. If the stockholders fail to ratify the selection, the Audit Committee will reconsider whether or not to retain that firm. Even if the selection is ratified, the Audit Committee 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 online or represented by proxy and entitled to vote on the matter at the Annual Meeting will be required to ratify the selection of Ernst & Young.

  2. Audit related fees consist of fees billed for professional services by Ernst & Young for accounting consultation services concerning financial accounting and reporting standards.
    All fees described above were pre-approved by the Audit Committee.

In connection with the audit of the 2019 financial statements, the Company entered into an engagement agreement with Ernst & Young that sets forth the terms by which Ernst & Young will perform audit services for the Company.

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, Ernst & Young. 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 Ernst & Young is compatible with maintaining the principal accountant's independence.

  1. In accordance with SEC rules, this column reflects the grant date fair value of RSUs and PRSUs granted during 2019 computed in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 718 for stock-based compensation transactions (ASC 718). The grant date fair value for RSUs and PRSUs is measured based on the closing price of the Company's common stock on the date of grant.
  2. In accordance with SEC rules, this column reflects the aggregate grant date fair value of the option awards granted during 2019 and 2018 , as applicable, computed in accordance with ASC 718. Assumptions used in the calculation of these amounts are included in Note 8 to our audited financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2019 . These amounts do not reflect the actual economic value that will be realized by the named executive officer upon the vesting of the stock options, the exercise of the stock options, or the sale of the common stock underlying such stock options. As a result of our December 2019 option exchange, as described further under "Offer Exchange Program" below certain stock options held by Mr. Abdollahian and Dr. Sandison were exchanged in December 2019 for new stock options. The option exchange was structured to approximate a "value-for-value" exchange, in the aggregate, for our executive officers for purposes of Section 16 of the Exchange Act, or Section 16 Officers, based on an exchange ratio of 1.5 to 1; however, on an individual basis, we recognized incremental fair value. Accordingly, the 2019 amounts listed in this column for Mr. Abdollahian and Dr. Sandison include the incremental fair value of the exchanged options ($48,651 and $29,837, respectively), computed as of the date of the exchange in accordance with ASC 718.

Compensation Program Overview

Our compensation program for executive officers is designed to encourage our management team to continually achieve our short-term and long-term corporate objectives while effectively managing business risks and challenges. We provide what we believe is a competitive total compensation package to our management team through a combination of base salary, an annual performance-based bonus and long-termequity-based incentives.

The compensation of our named executive officers other than our Chief Executive Officer is generally determined and approved by the Compensation Committee of our Board, and the compensation of our Chief Executive Officer is approved by our Board based upon the recommendations of the Compensation Committee.

Annual Base Salary

The 2019 base salaries for our named executive officers were as follows:

Annual Bonus Opportunity

In addition to base salaries, our named executive officers are eligible to receive annual performance-based cash bonuses, which are designed to provide appropriate incentives to our executives to achieve defined annual corporate and individual goals and to reward our executives for achievement towards these goals. The annual performance-based bonus that each named executive officer is eligible to receive is generally based on the extent to which we achieve the corporate goals the Board establishes each year, the extent to which the executive achieves any related individual goals and each executive's target bonus opportunity.

The target bonus percentages that Dr. Stein, Mr. Abdollahian and Dr. Sandison were eligible for under the bonus plan for 2019 were 60%, 40% and 40% of their base salaries, respectively. Dr. Stein's bonus award was weighted 100% for our achievement of corporate goals established by the Board. The bonus awards for Mr. Abdollahian and Dr. Sandison were weighted 80% for our achievement of corporate goals and 20% for achievement of individual goals approved by our Chief Executive Officer. Our corporate goals for 2019 , established by our Board upon recommendation of the Compensation Committee, were a mix of clinical, research and development and financial goals. For our executive officers, including our named executive officers, the actual bonus award for any year, if any, may be more or less than the applicable target, depending primarily on the Compensation Committee's determination of the extend to which we achieved the corporate goal component, other than for Dr. Stein, and the executive's individual performance with respect to such corporate goals. There is no minimum bonus percentage or amount established for the named executive officers and, as a result, the bonus amounts vary from year to year based on corporate and/or individual performance. Payments under the bonus plan may be made in cash, through the issuance of stock, stock options or another form of equity award, or by a combination thereof. The Compensation Committee has the right to terminate or change the bonus plan at any time and for any reason.

In March 2020 , upon recommendation of the Compensation Committee, our Board , reviewed our corporate goals and unanimously determined that on an overall basis, we achieved 85% of our corporate goals for 2019 . Upon the recommendation of the Compensation Committee having reviewed and approved the individual performances in the case of Mr. Abdollahian and Dr. Sandison, the Board awarded the bonuses, in the form of cash, in the Summary Compensation Table above.

Equity-Based Incentive Awards

Our equity-based incentive awards are designed to align our interests with those of our employees and consultants, including our named executive officers. The Compensation Committee is responsible for approving equity grants, other than those for our Chief Executive Officer and directors which are approved by our Board based upon the recommendation of the Compensation Committee. Our executives generally are awarded an initial new hire equity grant upon commencement of employment. Additional annual grants may also be made at the discretion of the Compensation Committee or Board in order to specifically incentivize executives with

24

respect to achieving certain corporate goals, reward executives for exceptional performance, or to ensure executives' equity holdings are consistent with our compensation philosophy.

Prior to our initial public offering, we granted all equity awards pursuant to our 2013 Stock Option and Grant Plan (the "2013 Plan"). Upon and following our initial public offering, all equity awards are granted under our 2015 Equity Incentive Plan (the "2015 Plan"). The terms of our 2013 Plan and 2015 Plan are described below under "Equity Benefit Plans." All options are granted with a per share exercise price equal to no less than the fair market value of a share of our common stock on the date of the grant of such award, as determined by the Compensation Committee or the Board. Generally our new hire equity awards vest over a four-year period and our annual equity awards vest over a three-year period, in each case subject to the holder's continuous service to us.

We granted annual equity awards to each of our named executive officers in early 2019. Our annual equity awards for Dr. Stein consisted of a mix of performance-vesting restricted stock units, or PRSUs, and stock options and for Mr. Abdollahian and Dr. Sandison, a mix of PRSUs, stock options and time-vesting restricted stock units, or RSUs.

  1. Options granted prior to April 2015 were granted under the 2013 Plan and options granted after April 2015 were granted under the 2015 Plan. Options granted under the 2013 Plan are immediately exercisable subject to a repurchase right held by us, which lapses as the shares vest. Options granted under the 2015 Plan become exercisable as they vest. The terms of the 2013 Plan and 2015 Plan are described below under "Equity Benefit Plans." All equity award vesting is subject to continued service of the executive.
  2. Stock options have a four-year vesting schedule, with 25% vesting on the one-year anniversary of the vesting commencement date, and monthly thereafter in equal increments over the remaining 36 months.
  3. Stock options have a three-year vesting schedule, vesting in equal monthly increments.
  4. Represents stock options covering 86,574 shares granted in the Option Exchange described below under "Option Exchange Program", in exchange for fully vested options covering 129,861 shares granted between July 1, 2016 and March 31, 2017 with a weighted average exercise price per share of $9.54. Pursuant to the Option Exchange, these stock options vest in full on the first anniversary of the grant date.
  5. Represents stock options covering 61,925 shares granted in the Option Exchange described below under "Option Exchange Program", in exchange for fully vested options covering 92,889 shares granted between October 30, 2015 and March 31, 2017 with a weighted average exercise price per share of $9.82. Pursuant to the Option Exchange, these stock options vest in full on the first anniversary of the grant date.
  6. Represents stock options covering 13,425 shares granted in the Option Exchange described below under "Option Exchange Program", in exchange for unvested options covering 20,139 shares granted between July 1, 2016 and March 31, 2017 with a weighted average exercise price per share of $9.72. Pursuant to the Option Exchange, these stock options have a three-year

27

vesting schedule, with 1/3 vesting on the one-year anniversary of the vesting commencement date, and monthly thereafter in equal increments over the remaining 24 months.

  1. Represents stock options covering 4,075 shares granted in the Option Exchange described below under "Option Exchange Program", in exchange for unvested options covering 6,111 shares granted on March 31, 2017 with an exercise price per share of $7.80. Pursuant to the Option Exchange, these stock options have a three-year vesting schedule, with 1/3 vesting on the one-year anniversary of the vesting commencement date, and monthly thereafter in equal increments over the remaining 24 months.
  2. The amount shown is determined by multiplying the number of unvested shares by $3.84, the closing price of the Company's common stock on December 31, 2019.
  3. Awards include RSUs that are subject to time-based vesting conditions and are scheduled to vest in two annual installments at January 1, 2020 and 2021, contingent on the officer's c ontinued service with the Company through the applicable vesting date.
  4. Awards include RSUs that are subject to time-based vesting conditions and are scheduled to vest in three annual installments at January 1, 2020, 2021 and 2022, contingent on the officer's c ontinued service with the Company through the applicable vesting date.
  5. Awards include PRSUs that are subject to performance-based vesting conditions and are scheduled to vest on the achievement of various clinical and corporate milestones, subject to the officer's continued service with the Company through the satisfaction of performance conditions.

Option Exchange Program

In November 2019, we commenced a tender offer under which eligible employees could tender certain eligible stock options with an exercise price greater than the greater of (i) $2.28 and (ii) the closing price of the Company's common stock on December 18, 2019, in exchange for new stock options (the "Option Exchange"). The Option Exchange was structured to be a "value-for-value" exchange, in the aggregate, for our Section 16 Officers (and one-for- one exchange for our other employees), provided for adjusted vesting schedules, imposing new vesting on fully vested options, and a seven year term for the new options, rather than our typical ten year term.

As of the commencement of the Option Exchange, approximately 94% of our outstanding employee stock options and 97% of outstanding stock options held by our Section 16 Officers were "underwater," meaning the exercise price of those options was greater than our stock price. A significant portion of these options had been "underwater" for more than 12 months. This meant that our historically granted stock options may have had little or no perceived value to those who held them and therefore no longer were effective as incentives to motivate and retain these individuals.

The Board believed that the Option Exchange was critical to our future success to revitalize the incentive value of our outstanding equity awards, and that new stock options granted would provide additional incentive to motivate and retain our talented employees. As an alternative to increased cash compensation, the Option Exchange allowed us to devote more of our cash resources towards advancing our clinical development programs. In addition, it provided the opportunity to reduce the "overhang" of outstanding stock options, as a substantial amount of "underwater" stock options were held by our Section 16 Officers who received a lesser number of shares for each option tendered, as described below. The Board also considered our competition's ability to attract and recruit top talent and viewed it as critical that we retain and motivate key employees through equity opportunities.

On December 18, 2019, we completed the Option Exchange. Tendered options were exchanged for new options based on (i) an exchange ratio of 1.5 to 1 in an approximate value-for-value exchange in the aggregate for Section 16 Officers and (ii) an exchange ratio of 1 to 1 for all other eligible employees. Each new option has a maximum term of seven years. To the extent an eligible option was vested as of December 18, 2019, such vested portion was exchanged for a new option that will vest in full on the first anniversary of the grant date. To the extent an eligible option was unvested as of December 18, 2019, such unvested portion was exchanged for a new options that will vest as follows: one-third of the shares will vest on the first anniversary of the grant date, and the balance of the shares will vest in twenty-four (24) equal monthly installments thereafter. Mr. Abdollahian exchanged options to purchase an aggregate of 150,000 shares of our common stock for new options to purchase 99,999 shares of common stock at $2.45 per share. Dr.

28

Sandison exchanged options to purchase an aggregate of 99,000 shares of our common stock for new options to purchase 66,000 shares of common stock at $2.45 per share. All surrendered options were canceled effective as of the closing of the Option Exchange.

We did not engage in any other repricings, modifications or cancellations of any of our named executive officers' outstanding equity awards during the year ended December 31, 2019 .

Perquisites Health, Welfare and Retirement Benefits

All of our named executive officers are eligible to participate in our employee benefit plans, including our medical, dental, vision, group life, disability and accidental death and dismemberment insurance plans, in each case on the same basis as our other employees. We also provide a 401(k) plan to our employees, including our named executive officers, as discussed in the section below entitled "401(k) Plan."

We do not provide any other perquisites or personal benefits to our named executive officers. We do, however, pay the premiums for term life insurance and disability insurance for all of our employees, including our current named executive officers.

401(k) Plan

We maintain a defined contribution employee retirement plan (the "401(k) Plan"), for our employees. Our named executive officers are eligible to participate in the 401(k) Plan on the same basis as our other employees. The 401(k) Plan is intended to qualify as a tax-qualified plan under Section 401(k) of the Code. The 401(k) plan provides that each participant may contribute a portion of his or her eligible compensation, up to the statutory annual limit, which was $19,000 for employees under age 50 and was $25,000 for employees age 50 and over in 2019. All contributions made by participants are either pre-tax contributions or after-tax "Roth 401(k) contributions," as elected by the participant. The plan permits us to make discretionary contributions, including matching contributions and discretionary profit sharing contributions. We did not provide any such contributions in 2018 for employee contributions made in 2017. In 2019 we made an employer matching contribution for 2018 employee pre-tax and Roth 401(k) contributions of twenty-five cents for every employee dollar electively deferred under the 401(k) Plan, limited to four percent of the participant's compensation and further subject to any limitations set forth by the Internal Revenue Service ("IRS"). The 401(k) Plan currently does not offer the ability to invest in our securities.

Nonqualified Deferred Compensation

None of our named executive officers participate in or have account balances in nonqualified defined contribution plans or other nonqualified deferred compensation plans maintained by us. The Board may elect to provide our officers and other employees with nonqualified defined contribution or other nonqualified deferred compensation benefits in the future if it determines that doing so is in our best interests.

Equity Benefit Plans

2015 Equity Incentive Plan

Our Board adopted the 2015 Plan in March 2015 and our stockholders approved the 2015 Plan in April 2015. The 2015 Plan became effective upon the execution and delivery of the underwriting agreement related to our initial public offering. Once the 2015 Plan became effective, no further grants were made under the 2013 Plan.

Stock Awards . The 2015 Plan provides for the grant of incentive stock options ("ISOs"), nonstatutory stock options ("NSOs"), stock appreciation rights, restricted stock awards, RSUs, performance-based stock awards, and other forms of equity compensation, or collectively, stock awards, all of which may be granted to employees, including officers, non-employee directors and consultants of us and our affiliates. Additionally, the 2015 Plan provides for the grant of performance cash awards. ISOs may be granted only to employees. All other awards may be granted to employees, including officers, and to non- employee directors and consultants.

Administration . Our Board, or a duly authorized committee thereof, has the authority to administer the 2015 Plan. Our Board may also delegate to one or more of our officers the authority to (1) designate employees (other than other officers) to be recipients of certain

29

stock awards, and (2) determine the number of shares of common stock to be subject to such stock awards. Subject to the terms of the 2015 Plan, our Board or the authorized committee, referred to herein as the plan administrator, determines recipients, dates of grant, the numbers and types of stock awards to be granted and the terms and conditions of the stock awards, including the period of their exercisability and the vesting schedule applicable to a stock award.

Subject to the limitations set forth below, the plan administrator will also determine the exercise price, strike price or purchase price of awards granted and the types of consideration to be paid for the award.

The plan administrator has the authority to modify outstanding awards under our 2015 Plan. Subject to the terms of our 2015 Plan, the plan administrator has the authority to reduce the exercise, purchase or strike price of any outstanding stock award, cancel any outstanding stock award in exchange for new stock awards, cash or other consideration, or take any other action that is treated as a repricing under generally accepted accounting principles, with the consent of any adversely affected participant.

Stock Options . ISOs and NSOs are granted pursuant to stock option agreements adopted by the plan administrator. The plan administrator determines the exercise price for a stock option, within the terms and conditions of the 2015 Plan, provided that the exercise price of a stock option generally cannot be less than 100% of the fair market value of our common stock on the date of grant. Options granted under the 2015 Plan vest at the rate specified by the plan administrator.

The plan administrator determines the term of stock options granted under the 2015 Plan, up to a maximum of ten years. Unless the terms of an optionholder's stock option agreement provide otherwise, if an optionholder's service relationship with us, or any of our affiliates, ceases for any reason other than disability, death or cause, the optionholder may generally exercise any vested options for a period of three months following the cessation of service. The option term may be extended in the event that exercise of the option following such a termination of service is prohibited by applicable securities laws or our insider trading policy. If an optionholder's service relationship with us or any of our affiliates ceases due to disability or death, or an optionholder dies within a certain period following cessation of service, the optionholder or a beneficiary may generally exercise any vested options for a period of 12 months in the event of disability and 18 months in the event of death. In the event of a termination for cause, options generally terminate immediately upon the termination of the individual for cause. In no event may an option be exercised beyond the expiration of its term.

Acceptable consideration for the purchase of common stock issued upon the exercise of a stock option will be determined by the plan administrator and may include (1) cash, check, bank draft or money order, (2) a broker-assisted cashless exercise, (3) the tender of shares of our common stock previously owned by the optionholder, (4) a net exercise of the option if it is an NSO, and (5) other legal consideration approved by the plan administrator.

Unless the plan administrator provides otherwise, options generally are not transferable except by will, the laws of descent and distribution, or pursuant to a domestic relations order. An optionholder may designate a beneficiary, however, who may exercise the option following the optionholder's death.

Restricted Stock Unit Awards . RSU awards are granted pursuant to restricted stock unit award agreements adopted by the plan administrator. RSU awards may be granted in consideration for any form of legal consideration. An RSU award may be settled by cash, delivery of stock, a combination of cash and stock as deemed appropriate by the plan administrator, or in any other form of consideration set forth in the restricted stock unit award agreement. Additionally, dividend equivalents may be credited in respect of shares covered by an RSU award. Except as otherwise provided in the applicable award agreement, RSUs that have not vested will be forfeited upon the participant's cessation of continuous service for any reason.

Corporate Transactions . In the event of certain specified significant corporate transactions, the plan administrator has the discretion to take any of the following actions with respect to stock awards:

  • arrange for the assumption, continuation or substitution of a stock award by a surviving or acquiring entity or parent company;
  • arrange for the assignment of any reacquisition or repurchase rights held by us to the surviving or acquiring entity or parent company;
  • accelerate the vesting of the stock award and provide for its termination at or prior to the effective time of the corporate transaction;

30

  • arrange for the lapse of any reacquisition or repurchase right held by us;
  • cancel or arrange for the cancellation of the stock award in exchange for such cash consideration, if any, as the Board may deem appropriate; or
  • make a payment equal to the excess of (1) the value of the property the participant would have received upon exercise of the stock award over
    (2) the exercise price otherwise payable in connection with the stock award.

Our plan administrator is not obligated to treat all stock awards, even those that are of the same type, in the same manner.

Under the 2015 Plan, a corporate transaction is generally the consummation of (1) a sale or other disposition of all or substantially all of our consolidated assets, (2) a sale or other disposition of at least 90% of our outstanding securities, (3) a merger, consolidation or similar transaction following which we are not the surviving corporation, or (4) a merger, consolidation or similar transaction following which we are the surviving corporation but the shares of our common stock outstanding immediately prior to such transaction are converted or exchanged into other property by virtue of the transaction.

Change of Control . The plan administrator may provide, in an individual award agreement or in any other written agreement between a participant and us, that the stock award will be subject to additional acceleration of vesting and exercisability in the event of a change of control. For example, certain of our employees may receive an award agreement that provides for vesting acceleration upon the individual's termination without cause or resignation for good reason (including a material reduction in the individual's base salary, duties, responsibilities or authority, or a material relocation of the individual's principal place of employment with us) in connection with a change of control. Under the 2015 Plan, a change of control is generally (1) the acquisition by a person or entity of more than 50% of our combined voting power other than by merger, consolidation or similar transaction; (2) a consummated merger, consolidation or similar transaction immediately after which our stockholders cease to own more than 50% of the combined voting power of the surviving entity; or (3) a consummated sale, lease or exclusive license or other disposition of all or substantially of our consolidated assets.

Amendment and Termination . Our board of directors has the authority to amend, suspend, or terminate our 2015 Plan, provided that such action does not materially impair the existing rights of any participant without such participant's written consent. No ISOs may be granted after the tenth anniversary of the date our Board adopted our 2015 Plan.

2013 Stock Option Plan

Our Board initially adopted and our stockholders approved the 2013 Plan in February 2013. The 2013 Plan provides for the grant of stock options (ISOs and NSOs), restricted stock awards, unrestricted stock awards and RSU awards to our employees, directors, and consultants. Only stock options and restricted stock awards were awarded under the 2013 Plan. Our Board, or a duly authorized committee thereof, has the authority to administer the 2013 Plan. Subject to the terms of the 2013 Plan, our Board determined recipients, dates of grant, the number of and types of awards granted and the terms and conditions of awards made, including any applicable vesting schedule. Awards under the 2013 Plan were granted pursuant to award agreements adopted by the plan administrator. No additional awards may be granted under the 2013 Plan. However, any outstanding awards already granted under the 2013 Plan will remain outstanding, subject to the terms of such plan and the applicable award agreements, until such outstanding awards are exercised or until they terminate or expire by their terms.

2015 Employee Stock Purchase Plan

Our Board adopted the 2015 Employee Stock Purchase Plan, or the ESPP, in March 2015 and our stockholders approved the ESPP in April 2015. The ESPP became effective immediately upon the execution and delivery of the underwriting agreement related to our initial public offering. The purpose of the ESPP is to retain the services of new employees and secure the services of new and existing employees while providing incentives for such individuals to exert maximum efforts toward our success and that of our affiliates.

Administration . Our Board has delegated its authority to administer the ESPP to our Compensation Committee. The ESPP is implemented through a series of offerings of purchase rights to eligible employees. Under the ESPP, we may specify offerings with

31

durations of not more than 27 months, and may specify shorter purchase periods within each offering. Each offering will have one or more purchase dates on which shares of our common stock will be purchased for employees participating in the offering. An offering may be terminated under certain circumstances.

Payroll Deductions . Generally, all regular employees, including executive officers, employed by us or by any of our designated affiliates, may participate in the ESPP and may contribute, normally through payroll deductions, up to 15% of their earnings for the purchase of our common stock under the ESPP. Unless otherwise determined by our Board, common stock will be purchased for accounts of employees participating in the ESPP at a price per share equal to the lower of (1) 85% of the fair market value of a share of our common stock on the first date of an offering or (2) 85% of the fair market value of a share of our common stock on the date of purchase.

Corporate Transactions . In the event of certain significant corporate transactions, including the consummation of: (1) a sale of all our assets, (2) the sale or disposition of 90% of our outstanding securities, (3) a merger or consolidation where we do not survive the transaction and (4) a merger or consolidation where we do survive the transaction but the shares of our common stock outstanding immediately prior to such transaction are converted or exchanged into other property by virtue of the transaction, any then-outstanding rights to purchase our stock under the ESPP may be assumed, continued or substituted for by any surviving or acquiring entity (or its parent company). If the surviving or acquiring entity (or its parent company) elects not to assume, continue or substitute for such purchase rights, then the participants' accumulated payroll contributions will be used to purchase shares of our common stock within ten business days prior to such corporate transaction, and such purchase rights will terminate immediately.

Plan Amendments, Termination . Our Board has the authority to amend or terminate our ESPP, provided that except in certain circumstances any such amendment or termination may not materially impair any outstanding purchase rights without the holder's consent. We will obtain stockholder approval of any amendment to our ESPP as required by applicable law or listing requirements.

Non-Employee Director Compensation

We maintain a non-employee director compensation policy approved by our Board based on the recommendation of the Compensation Committee. The policy originally became effective in 2015 and was amended by the Board, upon the recommendation of the Compensation Committee, in December 2016 and December 2019.

32

Between December 2016 and December 2019, the policy provided that each non-employee director would receive the following compensation for service on the Board:

  • an annual cash retainer of $40,000, or $65,000 for the Chairman of the Board;
  • an additional annual cash retainer of $7,500, $5,000 and $3,750 for service as a member of the Audit Committee, Compensation Committee and the Nominating and Corporate Governance Committee, respectively;
  • an additional annual cash retainer of $15,000, $10,000 and $7,500 for service as Chairman of the Audit Committee, Compensation Committee and the Nominating and Corporate Governance Committee, respectively (in lieu of the committee member retainer above);
  • an initial option grant to purchase 20,000 shares of our common stock on the date of each non-employee director's initial appointment to the Board, with 1/3 rd of the shares vesting on the first anniversary of the date of grant and the remaining shares vesting in equal monthly installments
    over the next two years, subject to acceleration of vesting in full upon a change of control; and
  • an annual option grant to purchase 11,000 shares of our common stock on the date of each of our annual stockholder meetings, which vests in one installment on the earlier of the first anniversary of the date of grant and the day prior to the date of our first annual stockholder meeting held after the date of grant, subject to acceleration of vesting in full upon a change of control.

The policy, as amended in December 2019, provides that each non-employee director will receive the following compensation for service on the Board:

  • an annual cash retainer of $40,000, or $65,000 for the Chairman of the Board;
  • an additional annual cash retainer of $7,500, $6,000 and $4,000 for service as a member of the Audit Committee, Compensation Committee and the Nominating and Corporate Governance Committee, respectively;
  • an additional annual cash retainer of $15,000, $12,000 and $8,000 for service as Chairman of the Audit Committee, Compensation Committee and the Nominating and Corporate Governance Committee, respectively (in lieu of the committee member retainer above);
  • an initial option grant to purchase 35,000 shares of our common stock on the date of each non-employee director's initial appointment to the Board, with 1/3 rd of the shares vesting on the first anniversary of the date of grant and the remaining shares vesting in equal monthly installments over the next two years, subject to acceleration of vesting in full upon a change of control; and
  • an annual option grant to purchase 17,500 shares of our common stock on the date of each of our annual stockholder meetings, which vests in one installment on the earlier of the first anniversary of the date of grant and the day prior to the date of our first annual stockholder meeting held after the date of grant, subject to acceleration of vesting in full upon a change of control.

We have reimbursed and will continue to reimburse all of our non-employee directors for their travel, lodging and other reasonable expenses incurred in attending meetings of the Board and committees of the Board.

The amounts reported reflect the aggregate grant date fair value of each equity award granted to our non-employee directors during the fiscal year ended December 31, 2019, as computed in accordance with FASB ASC 718. Assumptions used in the calculation of these amounts are included in Note 8 to our consolidated financial statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2019.

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

RELATED-PERSON TRANSACTIONS POLICY AND PROCEDURES

We have adopted a written related-person transactions policy that sets forth our policies and procedures regarding the identification, review, consideration and oversight of "related-person transactions." For purposes of our policy only, a "related-person transaction" is a transaction, arrangement or relationship (or any series of similar transactions, arrangements or relationships) in which we and any "related person" are participants involving an amount that exceeds $120,000.

Transactions involving compensation for services provided to us as an employee, consultant or director are not considered related-person transactions under this policy. A related person is any executive officer, director or a holder of more than 5% of our common stock, including any of their immediate family members and any entity owned or controlled by such persons.

Under the policy, where a transaction has been identified as a related-person transaction, management must present information regarding the proposed related-party transaction to our Audit Committee (or, where review by our Audit Committee would be inappropriate, to another independent body of our Board) for review. The presentation must include a description of, among other things, all of the parties, the direct and indirect interests of the related parties, the purpose of the transaction, the material facts, the benefits of the transaction to us and whether any alternative transactions are available, an assessment of whether the terms are comparable to the terms available from unrelated third parties and management's recommendation. To identify related- party transactions in advance, we rely on information supplied by our executive officers, directors and certain significant stockholders. In considering related-party transactions, our Audit Committee or another independent body of our Board takes into account the relevant available facts and circumstances including, but not limited to:

  • the risks, costs and benefits to us;
  • the impact on a director's independence in the event the related person is a director, immediate family member of a director or an entity with which a director is affiliated;
  • the terms of the transaction;
  • the availability of other sources for comparable services or products; and
  • the terms available to or from, as the case may be, unrelated third parties.

In the event a director has an interest in the proposed transaction, the director must recuse himself or herself from the deliberations and approval.

CERTAIN RELATED-PERSON TRANSACTIONS

The following includes a summary of transactions since January 1, 2018 to which we have been a party, in which the amount involved in the transaction exceeded the lesser of $120,000 or one percent of the average of the Company's total assets at year-end for the last two completed fiscal years. Since January 1, 2018 , the Company has engaged in the following transactions with related persons:

Employment Arrangements

We currently have written employment agreements with our executive officers. For information about our employment agreements with our named executive officers, refer to "Executive and Director Compensation- Agreements with our Named Executive Officers."

Stock Options Granted to Executive Officers and Directors

We have granted stock options to our executive officers and directors. For information about our stock option awards to our named executive officers and our directors, refer to "Executive and Director Compensation-Outstanding Equity Awards at Fiscal Year-End."

Indemnification Agreements

We have entered, and intend to continue to enter, into separate indemnification agreements with our directors and executive officers, in addition to the indemnification provided for in our amended and restated bylaws. These agreements, among other things, require us to indemnify our directors and executive officers for certain expenses, including attorneys' fees, judgments, fines and settlement amounts incurred by a director or executive officer in any action or proceeding arising out of their services as one of our directors or executive officers or as a director or executive officer of any other company or enterprise to which the person provides services at our request. We believe that these bylaw provisions and indemnification agreements are necessary to attract and retain qualified persons as directors and officers.

The limitation of liability and indemnification provisions in our amended and restated certificate of incorporation and amended and restated bylaws may discourage stockholders from bringing a lawsuit against directors for breach of their fiduciary duties. They may also reduce the likelihood of derivative litigation against directors and officers, even though an action, if successful, might benefit us and our stockholders. A stockholder's investment may decline in value to the extent we pay the costs of settlement and damage awards against directors and officers pursuant to these indemnification provisions.

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 Cidara 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 Cidara. Direct your written request to Cidara Therapeutics, Inc., Attn: Secretary, 6310 Nancy Ridge Drive, Suite 101, San Diego, CA 92121 or call us at (858) 752-6170. Stockholders who currently receive multiple copies of the Notice of Internet Availability of Proxy Materials at their addresses and would like to request "householding" of their communications should contact their brokers.
