Dear Iterum Therapeutics plc Shareholder,

You are cordially invited to our Extraordinary General Meeting of Shareholders (“EGM”) to be held at 3 Dublin Landings, North Wall Quay, Dublin 1, Ireland on August 1, 2023 at 3.00 p.m., Irish time (10.00 a.m., Eastern Time).

The purpose of the EGM is to ask shareholders to grant the board of directors an updated power under Irish law to issue shares for cash without first having to offer those shares to existing shareholders under pre-emptive rights that would otherwise apply to the issuance. This pre-emption opt-out proposal is required as a matter of Irish law and is not otherwise applicable to the non-Irish, Nasdaq listed companies with which we compete. Receipt of this authority would merely place us on par with other Nasdaq-listed companies and provide us with the flexibility to undertake the capital raising that we believe may be necessary from time to time to allow us to continue to execute on our business plans and strategy.

The enclosed Notice of EGM and the accompanying proxy statement set forth more detail on the proposal that will be presented at the meeting. Our board of directors unanimously recommends a vote “FOR” Proposal No. 1 as set forth in the proxy statement.

We hope that you will participate in the meeting by voting through acceptable means as described in this proxy statement as promptly as possible. Your vote is important – so please exercise your right.

Sincerely,

____________________________

Corey N. Fishman

President and Chief Executive Officer

INFORMATION ABOUT AN Extraordinary General Meeting and voting

This proxy statement is furnished in connection with the solicitation of proxies by the board of directors (the "board of directors" or the "board") of Iterum Therapeutics plc (the "Company," "Iterum," "we" or "us") for use at an Extraordinary General Meeting of Shareholders (the "EGM") to be held on August 1, 2023, beginning at 3.00 p.m., Irish time (10.00 a.m., Eastern Time), at 3 Dublin Landings, North Wall Quay, Dublin 1, Ireland and at any adjournment or postponement thereof. On June 12, 2023, the record date for the determination of shareholders entitled to vote at the EGM, there were issued, outstanding and entitled to vote an aggregate of [ ] of our ordinary shares, nominal value $0.01 per share ("ordinary shares"). Each ordinary share entitles the record holder thereof to one vote on each of the matters to be voted on at the EGM.

We have engaged Georgeson LLC, ("Georgeson"), to assist with the solicitation of proxies on our behalf. Please contact Georgeson with any queries at +1-800-457-0759.

Your vote is important no matter how many shares you own. Please take the time to vote. Take a moment to read the instructions below. Choose the way to vote that is easiest and most convenient for you and cast your vote as soon as possible.

If you are the "record holder" of your shares, meaning that you own your shares in your own name and not through a bank, broker or other nominee, you may vote in one of four ways:

(1)You may vote over the Internet. You may vote your shares by following the "Online" instructions on the enclosed proxy card. If you vote over the Internet, you do not need to vote by telephone or complete and mail your proxy card. The internet voting facilities for eligible shareholders of record will close at 4.59 a.m., Irish time on August 1, 2023 (11.59 pm, Eastern Time on July 31, 2023).

(2)You may vote by telephone. You may vote your shares by following the "Phone" instructions on the enclosed proxy card. If you vote by telephone, you do not need to vote over the Internet or complete and mail your proxy card. If you vote by telephone, your use of that telephone system, and specifically the entry of your pin number/other unique identifier, will be deemed to constitute your appointment, in writing and under hand, and for all purposes of the Irish Companies Act 2014, of each of David G. Kelly, Louise Barrett and Kevin Dalton as your proxy to vote your shares on your behalf in accordance with your telephone instructions. The telephone voting facilities for eligible shareholders of record will close at 4.59 a.m., Irish time on August 1, 2023 (11.59 pm, Eastern Time on July 31, 2023).

(3)You may vote by mail. You can vote by completing, dating and signing the proxy card provided to you and promptly mailing it in the provided postage-paid envelope. If you vote by mail, you do not need to vote over the Internet or by telephone. We must receive the completed proxy card by 5.00 p.m., Irish time (12.00 p.m., Eastern Time), on July 31, 2023.

(4)You may vote in person. If you attend the EGM, you may vote by delivering your completed proxy card in person or you may vote by completing a ballot at the EGM. Ballots will be available at the EGM. You may obtain directions to the location of the EGM by requesting them in writing or by telephone as follows: c/o Secretary, Iterum Therapeutics plc, Fitzwilliam Court, 1st Floor, Leeson Close, Dublin 2, Ireland, Phone: +353 1 9038354.

All proxies that are executed and delivered by mail or in person or are otherwise submitted online or by telephone will be voted on the matters set forth in the accompanying Notice of Extraordinary General Meeting of Shareholders in accordance with the shareholders' instructions. However, if no choice is specified on a proxy as to one or more of the proposals, the proxy will be voted in accordance with the board of directors' recommendations on such proposals as set forth in this proxy statement. All proxies will be forwarded to the Company's registered office electronically.

After you have submitted a proxy, you may still change your vote and revoke your proxy prior to the EGM by doing any one of the following things:

•submitting a new proxy by following the "Online" or " Phone" instructions on the enclosed proxy card at a date later than your previous vote but prior to the voting deadline (which is 4.59 a.m., Irish time on August 1, 2023 (11.59 pm, Eastern Time on July 31, 2023));

•signing another proxy card and either arranging for delivery of that proxy card by mail to the registered office of the Company prior to the start of the EGM, or by delivering that signed proxy card in person at the EGM;

•giving our Secretary a written notice before or at the EGM that you want to revoke your proxy; or

•voting in person at the EGM.

Your attendance at the EGM alone will not revoke your proxy.

If the shares you own are held in "street name" by a bank, broker or other nominee record holder, which we collectively refer to in this proxy statement as "brokerage firms," your brokerage firm, as the record holder of your shares, is required to vote your shares according to your instructions. To vote your shares, you will need to follow the directions your brokerage firm provides you. Many brokerage firms also offer the option of voting over the Internet or by telephone, instructions for which, if available, would be provided by your brokerage firm on the voting instruction form that it delivers to you. Because many brokerage firms are member organizations of the New York Stock Exchange (“NYSE”), the rules of the NYSE will likely govern how your brokerage firm would be permitted to vote your shares in the absence of instruction from you. Under the current rules of the NYSE, if you do not give instructions to your brokerage firm, it may still be able to vote your shares with respect to certain "discretionary" items. Proposal No. 1 is expected to be considered a discretionary item under NYSE rules and therefore your brokerage firm may be able to vote on that item even if it does not receive instruction from you, provided it holds your shares in its name. In the event a bank, broker or other nominee record holder determines that it does not have authority or otherwise does not exercise discretionary authority to vote on Proposal No. 1, it may deliver "broker non-votes" for such shares.

If your shares are held in street name, you must bring an account statement from your brokerage firm showing that you are the beneficial owner of the shares as of the record date (June 12, 2023) to be admitted to the EGM. To be able to vote your shares held in street name at the EGM, you will need to request a "legal proxy" from the bank, broker or nominee.

Votes Required

One or more Members (as defined in the Company’s Constitution) whose name is entered in the register of members of the Company as a registered holder of the Company's ordinary shares, present in person or by proxy (whether or not such Member actually exercises his voting rights in whole, in part or at all) holding not less than a majority of the issued and outstanding ordinary shares of the Company entitled to vote at the EGM, will constitute a quorum for the transaction of business at the EGM. Ordinary shares represented in person or by proxy (including any "broker non-votes" as described above) and shares which abstain or do not vote with respect to one or more of the matters presented for shareholder approval) will be counted for the purposes of determining whether a quorum is present at the EGM. The following votes are required for approval of the proposals being presented at the EGM:

Proposal No. 1: To grant the board of directors authority under Irish law to issue shares (including rights to acquire shares) for cash without first offering those shares to existing shareholders under pre-emptive rights that would otherwise apply to the issuance. The affirmative vote of the holders of ordinary shares representing at least 75% of the votes cast on the matter and voting affirmatively or negatively is required in order to grant the board of directors authority under Irish law to issue shares (including rights to acquire shares) for cash without first offering those shares to existing shareholders under pre-emptive rights that would otherwise apply to the issuance.

Shares that abstain from voting as to a particular matter and any broker non-votes will not be counted as votes in favor of such matter and will also not be counted as shares voting on such matter. Accordingly, abstentions and broker non-votes will have no effect on the voting on the proposal referenced above.

share ownership of certain beneficial owners and management

The following table sets forth information with respect to the beneficial ownership of our ordinary shares as of May 31, 2023 by:

(a)each person, or group of affiliated persons, known by us to beneficially own more than 5% of our ordinary shares;

(b)each of our named executive officers;

(c)each of our directors; and

(d)all of our executive officers and directors as a group.

Beneficial ownership is determined according to the rules of the Securities and Exchange Commission (the “SEC”) and generally means that a person has beneficial ownership of a security if he, she, or it possesses sole or shared voting or investment power of that security, including share options that are exercisable within 60 days of May 31, 2023, restricted share units that vest within 60 days of May 31, 2023, shares issuable upon exercise of warrants within 60 days of May 31, 2023, and shares issuable upon exchange of our outstanding 6.500% exchangeable senior subordinated notes due 2025 (the “Exchangeable Notes”) (assuming physical settlement), which are exchangeable within 60 days of May 31, 2023. Our ordinary shares issuable pursuant to share options, restricted share units, warrants and Exchangeable Notes, but not taking into account any additional ordinary shares issuable to satisfy accrued and unpaid interest due upon exchange of any Exchangeable Notes, are deemed outstanding for computing the percentage of the person holding such share options, restricted share units, warrants or Exchangeable Notes and the percentage of any group of which the person is a member, but are not deemed outstanding for computing the percentage of any other person. Except as indicated by the footnotes below, we believe, based on the information furnished to us, that the persons named in the table below have sole voting and investment power with respect to all ordinary shares shown that they beneficially own, subject to community property laws where applicable. The information does not necessarily indicate beneficial ownership for any other purpose, including for purposes of Section 13(d) and 13(g) of the Securities Act of 1933, as amended. Percentage ownership is based on 12,974,223 ordinary shares outstanding on May 31, 2023. Except as otherwise set forth below, the address of the beneficial owner is c/o Iterum Therapeutics plc, Fitzwilliam Court, 1st Floor, Leeson Close, Dublin 2, Ireland.

MATTER TO BE VOTED ON

PROPOSAL 1: BOARD AUTHORITY TO ISSUE ORDINARY SHARES FOR CASH WITHOUT FIRST OFFERING ORDINARY SHARES TO EXISTING SHAREHOLDERS

We are asking our shareholders to empower the board to allot the authorized but unissued ordinary share capital of the Company for cash without having to offer them to all existing shareholders in accordance with the statutory pre-emption right under the Irish Companies Act 2014.

Overview

•Under Irish law before a company can issue ordinary shares or other securities convertible into or exercisable or exchangeable for ordinary shares, for cash, the company must first offer those shares on the same or more favorable terms to existing shareholders of the company on a pro-rata basis. This is commonly referred to as the statutory pre-emption right.

•The statutory pre-emption right can be dis-applied, or opted-out of, by approval of the shareholders in order to give boards the ability to more efficiently and cost-effectively access the capital markets. These opt-out approvals are valid for a maximum period of five years.

•Pursuant to a resolution passed at an extraordinary general meeting of the company on January 28, 2021, our board is currently authorized to allot and issue up to 20,000,000 ordinary shares and 100,000,000 preferred shares (the "Previously Exempt Shares") for cash without first offering those shares to our existing shareholders under the pre-emption opt out authority until January 26, 2026.

•In May 2023, our shareholders granted our board of directors authority to allot up to an additional 60,000,000 ordinary shares for cash. As required by Irish law, our shareholders must vote to waive or opt-out of the pre-emptive rights related to these additional 60,000,000 ordinary shares. This Proposal No. 1 seeks to both expand the waiver to cover the additional 60,000,000 ordinary shares and extend the current waiver for the Previously Exempt Shares for another five years.

•This pre-emption opt-out approval is required solely because we are incorporated in Ireland. Companies incorporated in the United States are not subject to similar share issuance restrictions. Instead, U.S. investors generally appear to accept that companies often need to access capital markets quickly, and that potential concerns associated with affording boards flexibility in this respect are adequately protected against by other factors, including the Nasdaq shareholder approval requirements applicable to certain share issuances, which we are also subject to as a Nasdaq listed company.

•Shareholder approval of the pre-emption opt-out proposal does not mean that our board would have no limits on future share issuances. We are subject to the full reporting requirements of Section 12 of the Securities Exchange Act of 1934, as amended, and as such, approval of this authority would not exempt us from applicable Nasdaq shareholder approval requirements or compliance with applicable SEC disclosure rules and other regulations. For example, Nasdaq rules generally require shareholder approval in the following circumstances, which will continue to apply, even if the pre-emption opt-out is granted:

oany issuance or potential issuance that will result in a “change of control” (generally a transaction which results in an investor or group of affiliated investors obtains a 20% interest in our voting securities or the right to obtain a 20% interest in our voting securities); and

oissuances that exceed 20% of the pre-transaction total shares outstanding which are sold at a discount (meaning a price that is the lower than (1) the closing price immediately preceding the signing of the transaction agreement; or (2) the average closing price of the ordinary shares for the five trading days immediately preceding the signing of the transaction agreement).

•We currently have no specific plans, arrangements or understandings to issue the additional ordinary shares for cash if this Proposal No. 1 is approved by our shareholders, but we may need to engage in capital raising for many reasons in the future. Specifically, our future capital requirements will depend on numerous factors, including, without limitation, the timing and costs associated with completing our ongoing Phase 3 clinical trial evaluating oral sulopenem for the treatment of uncomplicated urinary tract infection ("uUTI") in adult women and the potential resubmission of our new drug application (“NDA”) for oral sulopenem to the U.S. Food and Drug Administration; the amount and timing of any payments we may be required to make in connection with the repayment of the 6.500% exchangeable senior subordinated notes due 2025 (the "Exchangeable Notes"); the outcome, timing and costs of seeking regulatory approvals, including with respect to the NDA for oral sulopenem; the costs of establishing commercial manufacturing arrangements; the costs of preparing, filing and prosecuting patent applications and maintaining, enforcing and defending intellectual property-related claims; pre-commercialization and commercialization costs; and the timing, receipt, and amount of revenues or royalties, if any, from any approved drug candidates.

Certain Effects of this Proposal

If Proposal No. 1 is approved, it will renew the authority that enables us to have flexibility to issue shares, including through capital raises, and to fund our development operations.

•Approval of Proposal No. 1 would provide us with the ability to more efficiently and cost-effectively access the capital that we believe is necessary for us to continue to execute on our business plans and strategy.

•Our growth strategy depends on our ability to research, develop, and commercialize our product candidates, which requires significant capital.

•Our board of directors and management rely heavily on having the flexibility to quickly take advantage of opportunities to raise capital through share issuances for cash to fund the execution of our business plans and strategy.

•The granting of the pre-emption rights opt-out authority eliminates the competitive disadvantage we are placed at compared to non-Irish, Nasdaq listed public companies and the risks associated with seeking transaction-specific shareholder approvals or having to first offer those shares that we propose to issue for cash to all of our existing shareholders in a time-consuming pro-rata rights offering.

If Proposal No. 1 is not approved, our ability to raise additional capital and continue growing our business would be severely limited.

•We are currently severely limited in the number of authorized and unissued shares we can offer for cash under our existing authority granted on January 28, 2021. If Proposal No. 1 is not approved, we would be limited under our existing authority to issuing only 4,927,431 ordinary shares (or rights to acquire such ordinary shares) for cash until January 26, 2026 without first offering such ordinary shares to our existing shareholders, based on the amount of authorized ordinary shares unissued or unreserved and therefor available for issuance under our existing authority as of May 31, 2023.

•As of March 31, 2023, we had cash, cash equivalents and short-term investments of $51.8 million, and as of May 12, 2023, we expected that our existing cash resources would be sufficient to enable us to fund our operations until mid-2024. Based solely on the last reported sale price of our ordinary shares on Nasdaq on May 31, 2023 of $1.15 per share, and assuming we issue for cash the maximum number of ordinary shares we are currently authorized to issue for cash pursuant to our existing authority, the maximum aggregate gross cash proceeds that we could potentially raise is $5.66 million. We currently have no specific plans, arrangements or understandings to issue the additional ordinary shares for cash and there can be no assurance that we would be able to raise such funds were we to attempt to do so. Moreover, given our recent share price, even if we were able to sell equity securities to fund our operations up to our current opt-out authority, we do not believe that such funds would be sufficient to allow us to become and remain profitable.

•We believe the requirement to conduct a rights offering in connection with our future equity-capital raising activities would negatively impact the price at which we are able to sell our shares and could potentially result in greater dilution to our existing shareholders, or require us to seek alternative funding arrangements which may be unavailable or only available on unfavorable terms. Our inability to raise funds efficiently when needed or on favorable terms may cause investors to lose confidence in us, which may cause our share price to decline. Without the ability to efficiently raise equity capital to fund our operations, we may be required to delay, limit, reduce or terminate our development program or grant rights to develop and market product candidates that we would otherwise prefer to develop ourselves.

•This vote is not about dilution. Our board of directors can still issue the 60,000,000 ordinary shares which were approved at the AGM in May 2023 even without approval of the pre-emption opt-out proposal. However, such issuances would entail more onerous, drawn out and costly processes, particularly given our very large shareholder base. For example, if the pre-emption opt-out proposal is not approved, in any capital raising transaction where we propose to issue shares (including rights to acquire shares) for cash consideration, we would be required to first offer those shares to all of our existing shareholders in a time-consuming pro-rata rights offering, which would (i) disadvantage us compared to non-Irish Nasdaq listed companies, (ii) significantly encumber and increase the cost of our capital-raising process and (iii) dramatically increase the timetable for completing any such financing transaction.

•Principal and interest on the outstanding Exchangeable Notes become due on January 31, 2025. We may not have enough available cash or be able to obtain financing at that time or, if Proposal No. 1 is not approved, be able to efficiently and cost effectively engage in equity-capital raising prior thereto. Our failure to make repayments when due would constitute a default under the indenture governing the Exchangeable Notes. A default under that indenture could also lead to a default under any agreements governing our future indebtedness.

The statutory pre-emption right applies only to share issuances for cash consideration; accordingly, it does not apply where we issue shares for non-cash consideration (such as in a share exchange transaction or in any transaction in which property other than cash is received by us in payment for shares) or, where we issue shares to employees pursuant to our employee equity compensation plans.

The text of the resolution in respect of this proposal is as follows:

“THAT the Company's directors be and are, with effect from the passing of this resolution, hereby empowered pursuant to Section 1023 of the Irish Companies Act 2014 to allot equity securities (including rights to acquire equity securities) within the meaning of the said Section 1023 for cash up to an aggregate nominal amount equal to the authorized but unissued share capital of the Company as if Section 1022 of the Irish Companies Act 2014 did not apply to any such allotment provided that this authority shall expire five years from the passing of this resolution and provided that the Company may before the expiry of such authority make an offer or agreement which would or might require equity securities to be allotted after such expiry and the Company's directors may allot equity securities in pursuance of such an offer or agreement as if the power conferred by this resolution had not expired.”

OUR BOARD OF DIRECTORS HAS UNANIMOUSLY DETERMINED THAT THIS PRE-EMPTION OPT-OUT PROPOSAL IS IN THE BEST INTERESTS OF THE COMPANY AND ITS SHAREHOLDERS AND RECOMMENDS THAT YOU VOTE FOR THE PRE-EMPTION OPT-OUT PROPOSAL.

OTHER MATTERS

The board of directors knows of no other business which will be presented to the EGM. If any other business is properly brought before the EGM, proxies will be voted in accordance with the judgment of the persons named therein.

Solicitation of Proxies

This proxy is solicited on behalf of our board of directors. We will bear the expenses connected with this proxy solicitation. In addition to the solicitation of proxies by mail, we expect to pay banks, brokers and other nominees their reasonable expenses for forwarding proxy materials and annual reports to principals and obtaining their voting instructions. In addition to the use of the mail, our directors, officers and employees may, without additional remuneration, solicit proxies in person or by use of other communications media. We have engaged Georgeson to solicit proxies from shareholders in connection with the EGM. We will pay Georgeson a fee of approximately $12,500, plus reasonable out of pocket fees and expenses for soliciting proxies. In addition, Georgeson and certain related persons will be indemnified against certain liabilities arising out of or in connection with the engagement. Proxies may be solicited by Georgeson by mail, telephone and e-mail.

Householding of Annual and Extraordinary Meeting Materials

Some banks, brokers and other nominee record holders may be participating in the practice of "householding" proxy statements. This means that unless otherwise instructed only one copy of our proxy statement or Notice of Internet Availability of Proxy Materials may have been sent to multiple shareholders in the same household. We will promptly deliver a separate copy of any such document to any shareholder upon request submitted in writing to us at Iterum Therapeutics plc, Fitzwilliam Court, 1st Floor, Leeson Close, Dublin 2, Ireland, Attention: Investor Relations, or orally by calling +353 1 9038354. Any shareholder who wants to receive separate copies of the proxy statement or Notice of Internet Availability of Proxy Materials in the future, or who is currently receiving multiple copies and would like to receive only one copy for his or her household, should contact his or her bank, broker or other nominee record holder, or contact us at the above address or phone number.
