#### TUHURA BIOSCIENCES, INC.

#### 2026 ANNUAL MEETING OF THE

#### STOCKHOLDERS
The Board of Directors of TuHURA Biosciences, Inc., a Nevada corporation ("TuHURA," "the Company," "we," "us" or "our"), has delivered these proxy materials to you in connection with the solicitation of proxies for use at the Company's 2026 Annual Meeting of Stockholders (the "Annual Meeting"). The Annual Meeting will be held live via Internet webcast on August 18, 2026, at ●, Eastern Time, or at any adjournment or postponement thereof, for the purposes stated herein.

A Notice of Internet Availability of Proxy Materials (the "Notice") is first being sent to stockholders on or about ●, 2026. The proxy materials, including this proxy statement and the accompanying proxy card, are being made available to stockholders on or about the same date. This proxy statement constitutes notice of the Annual Meeting in conformity with the requirements of applicable chapters of the Nevada Revised Statutes and our Bylaws.

#### Date, Time and Place of the Annual Meeting
The Annual Meeting will be held virtually via the Internet on August 18, 2026, at ●, Eastern Time. The Annual Meeting will be held in a virtual-only format conducted via live audio webcast. Only holders of our common stock as of the close of business on June 26, 2026 (the "Record Date") are entitled to receive notice of, and vote at, the Annual Meeting via the Annual Meeting website or any adjournment or postponement thereof. Our stockholders will be able to attend the Annual Meeting via the Annual Meeting website or by proxy, submit questions and vote their shares electronically during the meeting by visiting the Annual Meeting website at ● (the "Annual Meeting website"). Our stockholders will need the control number found on their proxy card or voting instruction form in order to access the Annual Meeting website.

#### Matters to Be Considered at the Annual Meeting
At the Annual Meeting, you will be asked to consider and vote on the following proposals:

1. To elect six directors nominated to serve until the 2027 annual meeting of the stockholders and until their successors have been duly elected and qualified, or until their earlier death, resignation or removal (the "Director Nomination Proposal");

2. To approve, in accordance with Nasdaq Listing Rule 5635(d), the issuance of an aggregate of 1,878,287 shares of our common stock issuable pursuant to that certain Fee Letter, dated April 21, 2026, between us and Parkview Holdings One LLC (the "Nasdaq Proposal ");

3. To approve, by non-binding advisory vote, the compensation of our named executive officers as disclosed in this proxy statement (the "Executive Compensation Proposal");

4. To approve, by non-binding advisory vote, the frequency of future advisory votes on the compensation paid to our named executive officers (the "Say-on-Frequency Proposal");

5. To ratify the appointment of Cherry Bekaert LLP as our independent registered public accounting firm for fiscal year ending December 31, 2026 (the "Auditor Ratification Proposal"); and

6. To transact such other business that may properly come before the meeting or any adjournments or postponements thereof (the "Adjournment Proposal").

#### Recommendation of the TuHURA Board of Directors
The TuHURA Board of Directors unanimously recommends that TuHURA stockholders vote:

• **Proposal 1**: "**FOR**" the director nominees as described in the Director Nomination Proposal;

• **Proposal 2**: "**FOR**" the Nasdaq Proposal;

• **Proposal 3**: "**FOR**" the Executive Compensation Proposal;

------

• **Proposal 4**: "**FOR**" the frequency of the non-binding advisory vote on executive compensation to occur every three years;

• **Proposal 5**: "**FOR**" the Auditor Ratification Proposal; and

• **Proposal 6**: "**FOR**" the Adjournment Proposal.

#### Record Date for the Annual Meeting and Voting Rights
The Record Date to determine who is entitled to receive notice of and to vote at the Annual Meeting or any adjournments or postponements thereof is June 26, 2026. As of the close of business on June 26, 2026, there were 63,682,528 shares of our common stock issued and outstanding and entitled to vote at the Annual Meeting. Each stockholder is entitled to one vote for any matter properly brought before the Annual Meeting for each share of our common stock such holder owned at the close of business on the Record Date. Only our stockholders of record at the close of business on the Record Date are entitled to receive notice of and to vote at the Annual Meeting and any and all adjournments or postponements thereof.

#### Quorum; Abstentions and Broker Non-Votes
A quorum of stockholders is necessary to conduct the Annual Meeting. The holders of at least one-third (1/3) of the voting power of the capital stock issued and outstanding and entitled to vote at the Annual Meeting must be present or represented at the Annual Meeting by proxy in order to constitute a quorum. Shares of our common stock represented at the Annual Meeting and entitled to vote, but not voted, including shares for which a stockholder directs an "abstention" from voting and broker non-votes, will be counted for purposes of determining a quorum. If a quorum is not present, the Annual Meeting will be postponed or adjourned until the holders of the number of shares of our common stock required to constitute a quorum attend.

Under the New York Stock Exchange ("NYSE") rules, banks, brokers or other nominees who hold shares in "street name" for a beneficial owner of those shares typically have the authority to vote in their discretion on "routine" proposals when they have not received instructions from beneficial owners. However, banks, brokers or other nominees are not allowed to exercise their voting discretion with respect to the approval of matters that the NYSE determines to be "non-routine." Generally, a broker non-vote occurs on an item when (a) a bank, broker or other nominee has discretionary authority to vote on one or more "routine" proposals to be voted on at a meeting of stockholders, but is not permitted to vote on other "non-routine" proposals without instructions from the beneficial owner of the shares and (b) the beneficial owner fails to provide the bank, broker or other nominee with such instructions. Under the NYSE rules, "non-routine" matters include the Director Nomination Proposal (Proposal 1), the Nasdaq Proposal (Proposal 2), the Executive Compensation Proposal (Proposal 3), the Say-on-Frequency Proposal (Proposal 4) and the Adjournment Proposal (Proposal 6). We expect that the Auditor Ratification Proposal (Proposal 5) will be considered a "routine" matter to be voted on at the Annual Meeting, meaning, that if you hold your shares in street name and do not provide voting instructions to your brokerage firm, your brokerage firm may still be able to vote your shares with respect to such proposals. If you hold your shares of our common stock in "street name," your shares will not be represented and will not be voted on any "non-routine" matter (Proposals 1, 2, 3, 4 and 6) unless you affirmatively instruct your bank, broker or other nominee how to vote your shares in one of the ways indicated by your bank, broker or other nominee. It is therefore critical that you cast your vote by instructing your bank, broker or other nominee on how to vote. **Other than the Auditor Ratification Proposal, the NYSE rules governing brokers' discretionary authority will not permit brokers to exercise discretionary authority regarding any of the other proposals to be voted on at the Annual Meeting.**

| | | |
|:---|:---|:---|
| **Proposal** |  | **Votes Necessary** |
| Proposal 1 | Director Nomination Proposal | Directors are elected by a plurality of the votes of the holders of shares present in person or represented by proxy and entitled to vote on the election of directors. The director nominees receiving the highest number of affirmative votes will be elected (up to the total number of directors to be elected).<br>Withheld votes and broker non-votes will not be treated as a vote for or against any particular director nominee and will not affect the outcome of the election. |
| Proposal 2 | Nasdaq Proposal | Approval of the Nasdaq Proposal requires the affirmative vote of the holders of a majority of the votes cast (meaning the number of votes cast "**FOR**" this proposal must exceed the votes cast "**AGAINST**"). A failure to vote, a broker non-vote or an abstention will have no effect on the outcome of the Nasdaq Proposal |
| Proposal 3 | Executive Compensation Proposal | Approval on a non-binding advisory basis of our executive compensation requires the affirmative vote of the holders of a majority of votes cast (meaning the number of votes cast "**FOR**" this proposal must exceed the votes cast "**AGAINST**"). A failure to vote, a broker non-vote or an abstention will have no effect on the outcome of the Executive Compensation Proposal. |
| Proposal 4 | Say-on-Frequency Proposal | The frequency alternative that receives the highest number of votes cast at the Annual Meeting will be considered the frequency alternative that is preferred by our stockholders. As a result, abstentions, broker non-votes, if any, and any other failure to submit a proxy or vote in person at the meeting will not affect the outcome of the vote of Proposal 4. |
| Proposal 5 | Auditor Ratification Proposal | Approval requires the affirmative vote of a majority of votes cast by the stockholders at the Annual Meeting (meaning the number of votes cast "**FOR**" this proposal must exceed the votes cast "**AGAINST**"). A failure to vote, a broker non-vote or an abstention will have no effect on the outcome of the Auditor Ratification Proposal. |
| Proposal 6 | Adjournment Proposal | Approval requires the affirmative vote of the holders of a majority of votes cast by the stockholders at the Annual Meeting (meaning the number of votes cast "**FOR**" this proposal must exceed the votes cast "**AGAINST**"). A failure to vote, a broker non-vote or an abstention will have no effect on the outcome of the Adjournment Proposal |

#### Methods of Voting
If you are a stockholder of record, you may vote by proxy through the Internet, by telephone or by mail, or by voting at the Annual Meeting via the Annual Meeting website. For shares held through a bank, broker or other nominee in "street name" instead of as a registered holder, you may vote by submitting your voting instructions to your bank, broker or other nominee. In most instances, you will be able to do this over the Internet, by telephone or by mail as indicated below. Please refer to the information from your bank, broker or other nominee on how to submit voting instructions. If you do not provide voting instructions to your bank, broker or other nominee, your shares of our common stock will not be voted on any proposal as your bank, broker or other nominee does not have discretionary authority to vote on any of the proposals to be voted on at the Annual Meeting. See the section entitled "The Annual Meeting—Quorum; Abstentions and Broker Non-Votes".

• *By the Internet*: If you are a stockholder of record, you can vote at ● and follow the instructions, 24 hours a day, seven days a week. You will need the 16-digit control number included in the Notice or on your proxy card (if you received a paper copy of the proxy materials).

------

• *By Telephone*: If you are a stockholder of record, you can vote using a touch-tone telephone by calling 1-800-PROXIES and follow the recorded instructions, 24 hours a day, seven days a week. You will need the 16-digit control number included in the Notice or on your proxy card (if you received a paper copy of the proxy materials).

• *By Mail*: If you have requested and received a paper copy of the proxy materials by mail, you may complete, sign, date and return by mail the paper proxy card or voting instruction form sent to you in the envelope provided to you with your proxy materials or voting instruction form.

Unless revoked, all proxies representing shares entitled to vote that are delivered pursuant to this solicitation will be voted at the Annual Meeting and, where a choice has been specified on the proxy card, will be voted in accordance with such specification. If you are a stockholder of record, proxies submitted over the Internet, by telephone or by mail as described above must be received by 11:59 p.m., Eastern Time, on August 17, 2026. To reduce administrative costs and help the environment by conserving natural resources, we ask that you vote through the Internet or by telephone, both of which are available 24 hours a day.

Notwithstanding the above, if you hold your shares in "street name" and you submit voting instructions to your bank, broker or other nominee, your instructions must be received by the bank, broker or other nominee before the deadline set forth in the information from your bank, broker or other nominee on how to submit voting instructions.

If you deliver a proxy pursuant to this proxy statement, but do not specify a choice with respect to any proposal set forth in this proxy statement, your underlying shares of our common stock will be voted on such uninstructed proposal in accordance with the recommendation of the Board of Directors. We do not expect that any matter other than the proposals listed above will be brought before the Annual Meeting and the Bylaws provide that the only business that may be conducted at the Annual Meeting are those proposals brought before the meeting pursuant to this proxy statement.

#### Revocability of Proxies
Any stockholder giving a proxy has the right to revoke it, including any proxy card you may have previously submitted, before the proxy is voted at the Annual Meeting by any of the following actions:

• sending a signed written notice of revocation to our corporate secretary;

• voting again by the Internet or telephone at a later time before the closing of the voting facilities at 11:59 p.m., Eastern Time, on the date before the Annual Meeting;

• submitting a properly signed proxy card with a later date; or

• attending virtually and voting at the Annual Meeting via the Annual Meeting website.

Attendance virtually at the Annual Meeting will not in and of itself constitute revocation of a proxy. A revocation or later-dated proxy received by us after the vote will not affect the vote. Our corporate secretary's mailing address is: 10500 University Center Drive, Suite 110, Tampa, Florida 33612, Attention: Corporate Secretary. If the Annual Meeting is postponed or adjourned, it will not affect the ability of holders of our common stock of record as of the Record Date to exercise their voting rights or to revoke any previously granted proxy using the methods described above; however, if a new Record Date is set for an adjourned meeting, a new quorum will be required to be established.

#### Proxy Solicitation Costs
We are soliciting proxies to provide an opportunity to all of our stockholders to vote on agenda items, whether or not the stockholders are able to attend the Annual Meeting or an adjournment or postponement thereof. We will bear the entire cost of soliciting proxies from our stockholders. In addition to the solicitation of

------

proxies by use of the Notice and through the Internet, we will request that banks, brokers and other nominee record holders send proxies and proxy material to the beneficial owners of our common stock and secure their voting instructions, if necessary. We may be required to reimburse those banks, brokers and other nominees on request for their reasonable expenses in taking those actions.

Proxies may be solicited on behalf of us or by our directors, officers and other employees in person or by the Notice, telephone, facsimile, messenger, the Internet or other means of communication, including electronic communication. Our directors, officers and employees will not be paid any additional amounts for their services or solicitation in this regard.

#### Attending the Annual Meeting
The Annual Meeting may be accessed via the Annual Meeting website, where our stockholders will be able to listen to the Annual Meeting, submit questions and vote online.

You are entitled to attend the Annual Meeting via the Annual Meeting website only if you were a stockholder of record as of the close of business on the Record Date, or you held your shares beneficially in the name of a bank, broker, trustee or other nominee as of the Record Date, or you hold a valid proxy for the Annual Meeting. If you were a stockholder of record at the close of business on the Record Date and wish to attend the Annual Meeting via the Annual Meeting website, you will need the control number on your proxy card. If a bank, broker, trustee or other nominee is the record owner of your shares of our common stock, you will need to obtain your specific control number and further instructions from your bank, broker, trustee or other nominee.

You may submit questions during the live audio webcast of the Annual Meeting via the Annual Meeting website. To ensure the Annual Meeting is conducted in a manner that is fair to all stockholders, we may exercise discretion in determining the order in which questions are answered and the amount of time devoted to any one question. We reserve the right to edit or reject questions we deem inappropriate, redundant or not relevant to the Annual Meeting's limited purpose.

**Technical assistance will be available for stockholders who experience an issue accessing the Annual Meeting. Contact information for technical support will appear on the Annual Meeting website before the start of the Annual Meeting.** 

#### Householding
Securities and Exchange Commission ("SEC") rules permit companies and intermediaries such as brokers to satisfy delivery requirements for proxy statements and notices with respect to two or more stockholders sharing the same address by delivering a single proxy statement, Notice or a single notice addressed to those stockholders. This process, which is commonly referred to as "householding," provides cost savings for companies. Some brokers household proxy materials, delivering a single proxy statement, Notice or notice 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 materials 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 proxy statement, Notice or notice, or if your household is receiving multiple copies of these documents and you wish to request that future deliveries be limited to a single copy, please notify your broker. You can request prompt delivery of a copy of this proxy statement by writing to TuHURA Biosciences, Inc., 10500 University Center Drive, Suite 110, Tampa, Florida 33612, Attention: Corporate Secretary or email us at monique@gilmartinIR.com.

#### Tabulation of Votes
Our Board of Directors will appoint an independent inspector of election for the Annual Meeting. The inspector of election will, among other matters, determine the number of shares of our common stock represented

------

at the Annual Meeting to confirm the existence of a quorum, determine the validity of all proxies and ballots and certify the results of voting on all proposals submitted to our stockholders.

#### Adjournments
If a quorum is present at the Annual Meeting but there are not sufficient votes at the time of the Annual Meeting to approve the Nasdaq Proposal, then TuHURA stockholders may be asked to vote on the Adjournment Proposal.

At any subsequent reconvening of the Annual Meeting at which a quorum is present, any business may be transacted that might have been transacted at the original meeting and all proxies will be voted in the same manner as they would have been voted at the original convening of the Annual Meeting, except for any proxies that have been effectively revoked or withdrawn before the time the proxy is voted at the reconvened meeting.

#### Assistance
If you need assistance voting or in completing your proxy card or have questions regarding the Annual Meeting, please contact TuHURA at (813) 875-6600 or write to TuHURA Biosciences, Inc., Attn: Investor Relations, 10500 University Center Drive, Suite 110, Tampa, Florida 33612.

#### TUHURA STOCKHOLDERS SHOULD CAREFULLY READ THIS PROXY STATEMENT IN ITS ENTIRETY FOR MORE DETAILED INFORMATION.

------

#### PROPOSAL 1: ELECTION OF DIRECTORS AT ANNUAL MEETING

Each of the six nominees listed below are incumbent directors. If elected at the Annual Meeting, each of these nominees would serve until the next annual meeting of the stockholders and until his successor has been duly elected and qualified, or, if sooner, until the director's death, resignation or removal. Because the number of nominees properly nominated for the Annual Meeting is the same as the number of directors to be elected, the election of directors at this Annual Meeting is uncontested.

Directors are elected by a plurality of the votes of the holders of shares present in person or represented by proxy and entitled to vote on the election of directors. In accordance with our Bylaws and the Nevada Revised Statutes, a stockholder entitled to vote for the election of directors may withhold authority to vote for certain nominees for directors or may withhold authority to vote for all nominees for directors. Withheld votes and broker non-votes will not be treated as a vote for or against any particular director nominee and will not affect the outcome of the election. Stockholders may not vote, or submit a proxy, for a greater number of nominees than the six nominees named below. The director nominees receiving the highest number of affirmative votes will be elected. Shares of capital stock represented by executed proxies will be voted, if authority to do so is not withheld, for the election of the six director nominees named below. If any director 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 Board of Directors. Each person nominated for election has agreed to serve if elected. Our management has no reason to believe that any nominee will be unable to serve.

#### Nominees for Election Until the Next Annual Meeting
The following table sets forth the name, age and position of each of the nominees at the Annual Meeting:

---

| | | | |
|:---|:---|:---|:---|
| **Name** | **Age** | **Age** | **Position(s)** |
|  James Bianco, M.D. |  | 69 | Chief Executive Officer and Director |
|  James Manuso, Ph.D., MBA |  | 77 | Director and Chairman of the Board |
|  Alan List, M.D. |  | 71 | Director |
|  George Ng |  | 52 | Director |
|  Robert E. Hoffman |  | 60 | Director |
|  Craig Tendler, M.D. |  | 67 | Director |

---

#### Required Vote
The nominees for director who receive the most votes properly cast (also known as a plurality) will be elected. You may either vote "**FOR**" the nominees or "**WITHHOLD**" your vote from the nominees. Withheld votes and broker non-votes, if any, will have no effect on the Director Nomination Proposal.

Unless otherwise instructed, it is the intention of the persons named in the accompanying proxy card to vote shares represented by properly executed proxy cards "**FOR**" the election of the director nominees named in the Director Nomination Proposal. However, if the nominees are unable to serve or for good cause will not serve as a director, the proxies will be voted for the election of such substitute nominees as the Board of Directors may designate.

#### THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE "FOR" THE DIRECTOR NOMINEES NAMED IN THE DIRECTOR NOMINATION PROPOSAL.

#### TUHURA DIRECTORS, OFFICERS AND CORPORATE GOVERNANCE

#### Biographical Information Regarding Our Executive Officers and Director Nominees
The following is summary biographical information regarding our executive officers and director nominees:

#### Executive Officers
**James Bianco, M.D.** Dr. Bianco earned his M.D. from the Mount Sinai School of Medicine where, in his junior year, he was elected into Alpha Omega Alpha (AOA) medical honor society. He completed his residency and chief residency at the Mount Sinai Medical Center in New York City. He completed his fellowship in Hematology/Oncology at the University of Washington/Fred Hutchinson Cancer Research Center (FHCRC) where he was appointed Assistant Professor of Medicine, Assistant Member FHCRC and Director of the Bone Marrow Transplant Unit at a "Hutch" affiliate (SVAMC). He is the recipient of numerous awards including the National Organization of Rare Disease award for the development of Trisenox. He served on the Board of Trustees of the Friends of Jose Carreras Leukemia Foundation. In 2001, Dr. Bianco was named Washington CEO of the Year.

Dr. Bianco is a 33-year veteran of the biopharmaceutical industry. Dr. Bianco is the principal founder of CTI Biopharma, where he served as its CEO from 1992 to October 2016. Dr. Bianco's experience spans all aspects of drug development from phase I-IV clinical trials, regulatory approval, and pricing reimbursement to sales and marketing. He has extensive experience in financing, negotiating and execution of pharmaceutical development and commercial license agreements. During his tenure at CTI Biopharma, Dr. Bianco was responsible for strategic portfolio development and identifying, acquiring, licensing, purchasing, or acquiring through international merger and acquisition, five drug candidates, four of which have since been approved by the FDA and with three receiving accelerated or conditional regulatory approval in the U.S. and/or E.U. In 2013, Dr. Bianco led CTI Biopharma in the identification and negotiation of the asset purchase for VONJO<sup>®</sup> (pacritinib), a novel JAK2 selective tyrosine kinase inhibitor. He also led CTI Biopharma in the negotiation of the development and commercial license agreement with Baxalta. As CEO of CTI Biopharma, Dr. Bianco was also responsible for the PERSIST-2 Phase 3 trial design and conduct, the successful results of which served as the basis for the 2022 FDA accelerated approval of Vonjo<sup>®</sup> (pacritinib) and the subsequent acquisition of CTI Biopharma by SOBI for $1.75 billion.

Dr. Bianco joined Legacy TuHURA in 2021 as our Chief Executive Officer and as a director. He directed the completion of our reverse merger transaction with Kintara Therapeutics, Inc. in October 2024 (the "Kintara Merger"), and for TuHURA Biosciences, Inc., a Delaware corporation and wholly owned subsidiary of the Company ("Legacy TuHURA"), prior to the Kintara Merger since July 1, 2021. Dr. Bianco was also the founder, Chief Executive Officer and Chairman of TuHURA Biopharma, Inc., a biotechnology company, from its inception in November 2018 through its dissolution in January 2023, following the transfer of its assets to us.

We believe Dr. Bianco's experience in building and leading biotechnology businesses as well as his extensive clinical development experience provide him with the qualifications and skills to serve as a director of our company.

**Dan Dearborn** joined Legacy TuHURA in 2018 as its Chief Financial Officer and has served in this role for our company since the completion of the Kintara Merger. Mr. Dearborn is a CPA with over 25 years of finance experience exclusively with health care and biotechnology companies. Prior to joining our company, from 2015 to 2017, Mr. Dearborn was Chief Financial Officer at MYMD Pharmaceuticals, Inc., a biotechnology firm. Mr. Dearborn is an alumnus of Loyola University in Maryland and joined Ernst & Young early in his career. He was with Pharmerica, a long-term care pharmaceutical company, for fifteen years and advanced subsequently to a Director role. He then moved to BioDelivery Sciences International as Controller. During his time at BioDelivery Sciences International, the company signed two very large commercial partnership agreements and became listed on Nasdaq. Mr. Dearborn later joined Welldyne, Inc. ("Welldyne") as its Chief Financial Officer. Welldyne is a pharmacy benefit manager that also had several related health care businesses and employed associates in Florida and Colorado. During his time with Welldyne, the company was sold to the private equity firm Carlyle Group, Inc.

Manuso, Ph.D., MBA**, served as a director of Legacy TuHURA prior to the Kintara Merger since November 2022 and has served as our director and Chairman since the completion of the Kintara Merger. Dr. Manuso has also served as Chairman and Chief Executive Officer of Talfinium Investments, Inc., an investment entity and financial consultancy, since 2014.

Dr. Manuso has served on the board of Ocuphire Pharma, Inc., a public company (NASDAQ:OCUP) developing Nyxol in advanced clinical trials for the treatment of multiple visual disorders, since November 2020. From 2015 until 2018, Dr. Manuso served as President, Chief Executive Officer and Vice Chairman of RespireRx Pharmaceuticals Inc.

Dr. Manuso is the author of numerous chapters, articles and books on topics including health care cost containment and biotechnology company management.

We believe that Dr. Manuso's extensive experience in the biopharmaceutical industry in finance, business development and management, and his experience as a member of the boards of directors of multiple pharmaceutical companies, both domestic and foreign, provide him with the qualifications and skills to serve as a director of our company.

**George Ng** served as a director of Legacy TuHURA prior to the Kintara Merger since February 2020 and has served as a director of our company since the completion of the Kintara Merger. Mr. Ng has also served as a director of Calidi Biotherapeutics, Inc.

Mr. Ng holds a J.D. degree from the University of Notre Dame School of Law, as well as a B.A./B.S. double degree in Biochemistry and Economics from the University of California, Davis.

We believe that Mr. Ng's experience with the launch and commercialization efforts of multiple pharmaceutical drug products, experience in clinical research procedures, and his executive experience in the biotechnology industry, provide him with the qualifications and skills to serve as a director of our company.

Mr. Hoffman holds a B.B.A. from St. Bonaventure University.

------

We believe Mr. Hoffman's financial and executive business experience qualifies him to serve as a director of our company.

**Craig Tendler, M.D.** was appointed as a member of our board of directors on March 10, 2025, and since March 2026, he has also provided consulting services to the Company through an affiliated entity. Dr. Tendler is an experienced pharmaceutical and biotech industry professional. From January 2010 through December 2024, Dr. Tendler served as the Vice President, Oncology Clinical Development, Diagnostics, and Global Medical Affairs of Johnson & Johnson Innovative Medicine Research & Development where he was responsible for creating and overseeing robust development plans, including optimal integration of biomarkers and diagnostics, and comprehensive data generation activities for all products in the oncology portfolio. During his tenure at Johnson & Johnson, Dr. Tendler and his team worked in collaboration with the FDA and the European Medicines Agency to secure worldwide approvals of transformational treatments in prostate cancer, hematologic malignancies, as well as for lung and bladder cancer.

We believe Dr. Tendler's experience in the pharmaceutical and biotech industry qualifies him to serve as a director of our company.

#### Board Composition
Our Board of Directors consists of six members. Our articles of incorporation provide that directors are to be elected at each annual meeting of stockholders to hold office until the expiration of the term for which elected and until such director's successor is elected and qualified or until such director's earlier death, resignation, or removal.

#### Director Independence
Based on information provided by each director concerning his background, employment and affiliations, each of the directors on our Board of Directors, other than Dr. James Bianco and Robert E. Hoffman, currently qualifies as an independent director, as defined under Nasdaq listing rules (the "Nasdaq listing rules"), and our Board of Directors consists of a majority of "independent directors," as defined under the rules of the SEC and Nasdaq listing rules relating to director independence requirements. In addition, we are subject to the rules of the SEC and Nasdaq relating to the membership, qualifications, and operations of certain committees of our board of directors, as discussed below.

On March 18, 2026, we entered into a Consulting Agreement with Tendler Biotech Consulting LLC ("Tendler Biotech"), an entity owned by our director Craig Tendler, under which Dr. Tendler provides, through Tendler Biotech, specified consulting services on an as-requested basis relating to our development strategy and operations in connection with our product pipeline. As a result of this Consulting Agreement, pursuant to which Tendler Biotech will receive an hourly fee, Dr. Tendler may in the future cease to be considered an "independent director" of the Company. In the event consulting fees payable to Tendler Biotech under the Consulting

------

Agreement exceed $120,000 in a calendar year, Dr. Tendler will cease to be considered an "independent director" of the Company. Upon such event, we will identify an additional "independent director" within the 180-day grace period provided under Nasdaq rules.

#### Committees of Our Board of Directors
Our Board of Directors has established an Audit Committee, a Compensation Committee, and a Nominating and Corporate Governance Committee, each of which operates pursuant to a charter adopted by our Board of Directors. Our Board of Directors may also establish other committees from time to time to assist our company and our board of directors.

#### Audit Committee
The Audit Committee oversees and monitors our financial reporting process and internal control system, reviews and evaluates the audit performed by our registered independent public accountants and reports to our board of directors any substantive issues found during the audit. The Audit Committee is directly responsible for the appointment, compensation and oversight of the work of our registered independent public accountants. The Audit Committee reviews and approves all transactions with affiliated parties.

The Audit Committee consists of James Manuso, Ph.D., MBA (chairman), Alan List, M.D., and George Ng. Our Board of Directors has also reviewed the education, experience and other qualifications of each member of the Audit Committee and based upon such review, has determined that Dr. Manuso is an "audit committee financial expert", as defined by the rules of the SEC.

To qualify as independent to serve on our Audit Committee, listing standards of Nasdaq and the applicable SEC rules require that a director not accept any consulting, advisory or other compensatory fee from us, other than for service as a director, or be an affiliated person of our company.

#### REPORT OF THE AUDIT COMMITTEE\*
The undersigned members of the Audit Committee of the Board of Directors of TuHURA Biosciences, Inc. submit this report in connection with the Audit Committee's review of the financial reports for the fiscal year ended December 31, 2025 as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. The Audit Committee has reviewed and discussed with management the audited financial statements for the Company for the fiscal year ended December 31, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. The Audit Committee has discussed with representatives of Cherry Bekaert LLP, the independent public accounting firm, the matters which are required to be discussed with them under the provisions of Auditing Standard No. 61, as amended (Communications with Audit Committees).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. The Audit Committee has discussed with Cherry Bekaert LLP, the independent public accounting firm, the auditors' independence from management and the Company has received the written disclosures and the letter from the independent auditors required by applicable requirements of the Public Company Accounting Oversight Board.

In addition, the Audit Committee considered whether the provision of non-audit services by Cherry Bekaert LLP, is compatible with maintaining its independence. In reliance on the reviews and discussions referred to above, the Audit Committee recommended to the Board of Directors (and the Board of Directors has approved) that the audited financial statements be included in TuHURA's Annual Report on Form 10-K for the fiscal year ended December 31, 2025 filed with the Securities and Exchange Commission.

Audit Committee of TuHURA Biosciences, Inc.

James Manuso, Ph.D.,

Alan List, M.D.,

George Ng

\* The foregoing report of the Audit Committee is not to be deemed "soliciting material" or deemed to be "filed" with the Securities and Exchange Commission (irrespective of any general incorporation language in any document filed with the Securities and Exchange Commission) or subject to Regulation 14A of the Securities Exchange Act of 1934, as amended, or to the liabilities of Section 18 of the Securities Exchange Act of 1934, except to the extent we specifically incorporate it by reference into a document filed with the Securities and Exchange Commission. 

#### Compensation Committee
The Compensation Committee assists our Board of Directors in fulfilling its oversight responsibilities relating to compensation of the directors and executive officers of our company and the administration of compensation plans of our company.

The Compensation Committee consists of Alan List, M.D. (chairman) and James Manuso, Ph.D., MBA. Each member of our Compensation Committee is a "non-employee" director within the meaning of Rule 16b-3 of the rules promulgated under the Exchange Act and independent within the meaning of the independent director guidelines of Nasdaq.

------

#### Compensation Committee Interlocks and Insider Participation
Each member of the Compensation Committee is a "non-employee" director within the meaning of Rule 16b-3 of the rules promulgated under the Exchange Act and independent within the meaning of the independent director guidelines of Nasdaq. None of our executive officers serve as a member of our Board of Directors or compensation committee of any entity that has one or more executive officers who are serving on our Board of Directors or Compensation Committee.

#### Nominating and Corporate Governance Committee
The Nominating and Corporate Governance Committee assesses potential director candidates to fill perceived needs on our Board of Directors for required skills, expertise, independence and other factors. A director candidate recommended by our stockholders will be considered in the same manner as a nominee recommended by a board member, management or other sources. Stockholders wishing to recommend a candidate for nomination should contact our Secretary in writing at our Corporate Secretary, c/o TuHURA at 10500 University Center Drive, Suite 110, Tampa, FL 33612. The Nominating and Corporate Governance Committee has discretion to decide which individuals to recommend for nomination as directors. The committee also develops and recommends corporate governance guidelines, oversees the evaluation of the Board of Directors and its committees, and makes recommendations to the Board of Directors regarding other corporate governance matters.

The Nominating and Corporate Governance Committee of our company consists of George Ng (chairman), Alan List, M.D. and Craig Tendler, M.D. We believe that the composition of the Nominating and Corporate Governance Committee meets the requirements for independence under, and the functioning of such Nominating and Corporate Governance Committee complies with, any applicable requirements of the rules and regulations of Nasdaq.

#### ADDITIONAL INFORMATION REGARDING THE TUHURA BOARD OF DIRECTORS AND CORPORATE GOVERNANCE

#### Code of Business Conduct and Ethics for Employees, Executive Officers, and Directors
We adopted a Code of Ethics and Conduct that applies to all of our executive officers, financial and accounting officers, our directors, financial managers and all of our employees. Each of the members of our Board of Directors is committed to a high standard of corporate governance practices and, through their respective oversight roles, encourage and promote a culture of ethical business conduct. A copy of our Code of Ethics and Conduct is posted under the "Investors" tab on our website, which is located at <u>www.tuhurabio.com</u>.

#### Insider Trading Policy
Our Board of Directors has adopted an Insider Trading Policy, which applies to all of our directors, officers and employees, as well as their family members and entities under their control. The policy prohibits such persons and entities from engaging in hedging transactions involving our equity securities, such as prepaid variable forward contracts, equity swaps, collars and exchange funds, or other transactions that hedge or offset, or are designed to hedge or offset, any decrease in the market value of our equity securities. A copy of our insider trading policy is filed as Exhibit 19.1 to our Annual Report on Form 10-K, as amended, for the fiscal year ended December 31, 2025.

#### Board Leadership Structure
We have structured our Board of Directors in a way that we believe effectively serves our objectives of corporate governance and management oversight. We separate the roles of President and Chairman of the Board of Directors in recognition of the differences between the two roles. We believe that the President should be responsible for the day-to-day leadership and performance of our Company, while the Chairman of the Board of Directors should work with the President and the rest of the Board of Directors to set the strategic direction for the Company and provide guidance to, and oversight of the President. The Chairman also sets the agenda for meetings of the Board of Directors and presides over them.

------

#### **Table of Contents**
Dr. Manuso, who is an independent director, was elected Chairman of the Board of Directors in 2024. In this capacity, Dr. Manuso, among other things, calls and presides over board meetings, including meetings of the independent directors, and sets meeting agendas. In this role, Dr. Manuso can effectively coordinate between the Board of Directors and management regarding risk management issues and the implementation of appropriate responses, and can help ensure the effective independent functioning of the Board of Directors in its oversight responsibilities. Accordingly, the Chairman has substantial ability to shape the work of the Board of Directors.

#### Role of the Board of Directors in Risk Oversight and Risk Management
One of the key functions of the Board of Directors is informed oversight of our risk management process. The Board of Directors does not have a standing risk management committee, but rather administers this oversight function directly through the Board of Directors as a whole, as well as through various standing committees of the Board of Directors that address risks inherent in their respective areas of oversight.

#### Meetings of the Board, Board and Committee Member Attendance and Annual Meeting Attendance
The Board of Directors met 9 times in 2025, the Audit Committee met 4 times in 2025, the Compensation Committee met 1 time in 2025, and there were no Nominating and Corporate Governance Committee meetings in 2025. All then current board members attended 75% or more of the meetings of the Board of Directors and of the committees on which they served during 2025. In addition, we encourage all of our directors and nominees for director to attend the Annual Meeting, but attendance is not mandatory.

#### Election of Board of Directors
Directors are elected by a plurality vote of the holders of shares present in person or represented by proxy and entitled to vote on the election of directors at annual stockholders' meetings.

#### Communications with the Board
Any securityholder or any other interested party who desires to communicate with our Board of Directors, our non-management directors or any specified individual director, may do so by directing such correspondence to the attention of the Secretary, TuHURA Biosciences, Inc., 10500 University Center Dr., Suite 110, Tampa, Florida 33612. The Secretary will forward the communication to the appropriate director or directors as appropriate.

#### Family Relationships
There are no family relationships among our directors and executive officers, or persons nominated or chosen by us to become a director.

#### Involvement in Certain Legal Proceedings
There have been no material legal proceedings that would require disclosure under the federal securities laws that are material to an evaluation of the ability or integrity of our directors or executive officers, or in which any director, officer, nominee or principal stockholder, or any affiliate thereof, is a party adverse to us or has a material interest adverse to us.

#### Delinquent Section 16(a) Reports
Section 16(a) of the Exchange Act requires our directors, executive officers and persons who beneficially own more than 10% of our common stock to file reports of ownership and changes of ownership with the SEC. Based solely on our review of the copies of such forms furnished to us, we believe that during the fiscal year ended December 31, 2025, all Section 16(a) filing requirements applicable to our officers, directors and greater than 10% beneficial owners were complied with on a timely basis, except for a late Form 4 filed by each of

------

#### **Table of Contents**
Dan Dearborn and James A. Bianco for a grant of stock options on December 12, 2025, and a late Form 4 filed by Craig Tendler for a grant of stock options on March 10, 2025.

#### EXECUTIVE COMPENSATION
On October 18, 2024, we completed our reverse merger transaction in accordance with the terms of the Agreement and Plan of Merger, dated as of April 2, 2024 (the "Kintara Merger Agreement"), by and among Kintara Therapeutics, Inc. ("Kintara"), TuHURA Biosciences, Inc., a privately held Delaware corporation ("Legacy TuHURA"), and Kayak Mergeco, Inc., a direct wholly owned subsidiary of Kintara ("Merger Sub"). Pursuant to the Kintara Merger Agreement, Merger Sub merged with and into Legacy TuHURA, with Legacy TuHURA surviving the merger and becoming our direct, wholly-owned subsidiary (the "Kintara Merger"). Effective at 12:03 a.m. Eastern Time on October 18, 2024, the merger was completed, and effective at 12:04 a.m. Eastern Time on October 18, 2024, Kintara Therapeutics, Inc. was renamed "TuHURA Biosciences, Inc."

At the effective time of the Kintara Merger, our management was replaced with the management of Legacy TuHURA. Unless otherwise indicated, the disclosures in this section regarding our common stock or securities convertible into common stock for periods or as of a date that precedes the closing of the Kintara Merger have been adjusted to give effect to the transactions and 35-for-1 reverse stock split consummated in connection with the Kintara Merger.

This discussion may contain forward-looking statements that are based on our current plans, considerations, expectations and determinations regarding future compensation programs. Actual compensation programs that we adopt in the future could vary significantly from our historical practices and currently planned programs summarized in this discussion.

Additionally, if Mr. Dearborn is terminated without cause, including by notice of non-extension of his employment agreement, or he resigns for good reason, as such terms are defined in his employment agreement, and he executes a release of claims in the form prescribed by us within 30 days of the termination, (A) we are obligated to pay to Mr. Dearborn (i) his Accrued Obligations, (ii) one year of his base salary plus an amount equal to the average of his two prior years' bonuses, paid in one lump sum within 30 days of the separation, and (iii) reimbursement for monthly premiums to continue health insurance for one year or until other health insurance is obtained by Mr. Dearborn and (B) any unvested portion of any outstanding options or unvested shares of our common stock granted to Mr. Dearborn will immediately vest and become exercisable and will remain exercisable for a period of seven years following the date of his separation. If Mr. Dearborn's termination occurs upon the same circumstances, except that it occurs immediately prior to, upon, or within two years following a Change of Control (as defined in Mr. Dearborn's employment agreement), Mr. Dearborn's bonus payment will instead be an amount equal to the greater of the average of the two prior years' bonuses or 50% of his base salary.

#### Equity Awards
We have historically provided long-term incentive compensation to the NEOs through grants of stock options to purchase shares of our common stock under the TuHURA Amended and Restated 2019 Equity Incentive Plan (the "2019 Plan") and the TuHURA 2024 Equity Incentive Plan (the "2024 Plan").

#### Retirement Plans

#### Other Compensation
All NEOs are eligible to participate in our employee benefit plans, including our medical, dental, vision, life and disability insurance plans, in each case on the same basis as all other employees, provided that we pay all

#### **Table of Contents**
premiums for the medical, dental, and vision plans for our executive officers. For the NEOs, we pay for and on behalf of each NEO life insurance premiums. We generally do not provide perquisites or personal benefits to our NEOs, except in limited circumstances.

#### Outstanding Equity Awards at Fiscal Year-End

#### Potential Payments Upon Termination or Change in Control
Under the employment agreements with the NEOs, in the event the NEO is terminated by us other than for "Cause" or by the NEO for "Good Reason," the NEO will be eligible for the following severance benefits if he executes a release of claims in the form prescribed by us within 30 days of the termination: (A) payment of (i) employee's Accrued Obligations, (ii) two years of base salary plus an amount equal to the greater of the average of such employee's two prior years' bonuses or 50% of such employee's then-base salary, paid in one lump sum within 30 days of the separation, and (iii) reimbursement for monthly premiums to continue health insurance for two years or until other health insurance is obtained by such employee and (B) any unvested portion of any outstanding options or unvested shares of our common stock granted to such employee will immediately vest and become exercisable and will remain exercisable for a period of seven years following the date of such employee's separation. If the termination of the NEO occurs upon the same circumstances, except that it occurs immediately prior to, upon, or within two years following a Change of Control (as defined in the NEO's employment agreements), the NEO's bonus payment will instead be an amount equal to the greater of the average of the two prior years' bonuses or 50% of his base salary. The Kintara Merger was not deemed a Change

------

#### **Table of Contents**
of Control for purposes of each NEO employment agreement, and the merger transaction with Kineta, Inc. was not deemed a Change of Control for purposes of each NEO employment agreement.

For purposes of the employment agreements and the outstanding stock options: "Cause" is defined as (i) gross negligence or willful misconduct in the performance of employee's duties to our company after written notice to employee and the failure to cure same within ten business days after receipt of written notice; (ii) refusal or failure to act in accordance with any lawful specific direction or order of our board of directors after written notice to employee of such refusal or failure and failure to cure the same within ten days after receipt of written notice; (iii) commission of any act of fraud with respect to us; (iv) employee's material breach of any written agreement or material policy of ours after written notice to employee of such breach and failure to cure, if curable, the same within ten business days after receipt of written notice; and (v) employee's conviction of, or plea of nolo contendere to, a crime which adversely affects our business or reputation, in each case as determined by our board of directors; (vi) employee's willful unauthorized disclosure of Confidential Information (as defined in our confidential disclosure policy); (vii) continued or excessive absences or tardiness, after an official warning has been issued and failure to cure (not including authorized leaves of absence, FMLA leave, or absences that are a result of an accommodation under ADA).

#### Policy Relating to Recovery of Erroneously Awarded Compensation (Clawback Policy)
We have instituted a clawback policy in accordance with the Nasdaq's final rules implementing the incentive-based compensation recovery provisions of the Dodd-Frank Wall Street Reform and Consumer Protection Act, effective October 2, 2023, to support a culture of focused, diligent and responsible management that discourages conduct detrimental to our growth. The policy applies to each person who serves as an executive officer of our company, as defined in Rule 10D-1(d) under the Exchange Act, which include our named executive officers (each, a "covered employee"). In the event of a qualifying financial restatement, a covered employee will be required to forfeit erroneously awarded incentive compensation to the Company to the extent required under applicable law.

#### Pay Versus Performance
The following section has been prepared in accordance with pay versus performance rules adopted by the SEC pursuant to the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010. Under these new rules, the SEC has developed a definition of pay, referred to as Compensation Actually Paid ("CAP"). We are required to calculate CAP for the NEOs and then compare it with certain of our performance measures. Stockholders should refer to our compensation philosophy discussion and analysis in this proxy statement for a complete description of how executive compensation relates to our performance measures and how our Compensation Committee makes its decisions related thereto. Our Compensation Committee did not consider this SEC-required pay versus performance analysis and disclosure below in making its pay decisions for any of the years shown.

The following table shows the past three fiscal years' total compensation for the NEOs as set forth in the Summary Compensation Table ("SCT"), the CAP to the NEOs (as determined pursuant to SEC rules), our total stockholder return ("TSR"), and our net loss. We are a "smaller reporting company," as defined in Rule 12b-2 under the Exchange Act, and have elected to provide in this proxy statement certain scaled disclosures permitted under the Exchange Act for smaller reporting companies.

SEC rules require certain adjustments be made to the SCT totals to determine CAP as reported in the pay versus performance table. CAP does not necessarily represent cash and/or equity value transferred to the applicable NEOs without restriction, but rather is a valuation calculated under applicable SEC rules. The methodology for calculating CAP as required by Item 402(v) of Regulation S-K takes into account, among others, changes in share price and its impact on the fair value of equity awards.

For information on our executive compensation program and the approach used by our Compensation Committee, please refer to the "Executive Compensation" narrative and the outstanding equity awards table. The

(1) The dollar amounts reported in each column (a) are the amounts of total compensation reported for Dr. Bianco (TuHURA's current Chief Executive Officer), and (b) Robert Hoffman (TuHURA's former Chief Executive Officer prior to the completion of the Kintara Merger).

(2) The dollar amounts reported in these columns represent the amount of "compensation actually paid" to TuHURA's PEOs and the average "compensation actually paid" to TuHURA's non-PEO NEOs, as computed in accordance with Item 402(v) of Regulation S-K, for each covered fiscal year. In accordance with these rules, these amounts reflect total compensation as set forth in the SCT for each year, adjusted as shown below. Equity values are calculated in accordance with FASB ASC Topic 718, and the valuation assumptions used to calculate fair values did not materially differ from those disclosed at the time of grant. The dollar amounts do not reflect the actual amount of compensation earned or received by or paid to the PEOs or non-PEO NEOs during the applicable fiscal year.

2024 and 2023, Dan Dearborn and Dennis Yamashita, and (iii) for the year ending June 30, 2023, Dennis Brown (TuHURA's former Chief Scientific Officer), and Scott Praill (TuHURA's former Chief Financial Officer).

(4) Cumulative TSR is calculated by dividing the sum of the cumulative amount of dividends for the measurement period, assuming dividend reinvestment, and the difference between TuHURA's share price at the end and the beginning of the measurement period by TuHURA's share price at the beginning of the measurement period. The beginning of the measurement period for each year in the table is December 31, 2022. No dividends were paid on stock or option awards in 2023, 2024 or 2025.

(5) The dollar amounts reported represent the amount of net income (loss) reflected in TuHURA's audited financial statements for (a) the years ending December 31, 2025, 2024 and 2023 and (b) the year ending June 30, 2023.

#### Analysis of Information Presented in the Pay Versus Performance Table
In accordance with Item 402(v) of Regulation S-K, we are providing the following descriptions of the relationships between information presented in the Pay Versus Performance table above. The following graphs display the CAP to our NEOs compared to our TSR and our net income (loss) for fiscal 2023, 2024 and 2025. We do not look to net income (loss) as a performance measure for our executive compensation program and instead look at operational metrics, such as drug development milestones, pipeline progress, regulatory compliance, intellectual property, partnerships and collaborations, and general financial health of the company.

#### Policies and Practices Regarding Long-Term Incentive Awards
Our Compensation Committee and senior management monitor our equity grant practices to evaluate whether such policies comply with governing regulations and are consistent with good corporate practices. When making regular annual equity grants, our Compensation Committee's practice is to approve them at its meeting in January of each year as part of the annual compensation review and after results for the preceding fiscal year become available. Because our Compensation Committee's regular meeting schedule is determined in the prior fiscal year, the proximity of any awards to other significant corporate events is coincidental. In addition, our Compensation Committee may make grants at any time during the year it deems appropriate, including with respect to new hires or transitions or for general retentive or incentive needs. We attempt to make equity awards during periods when it does not have material non-public information ("MNPI") that could impact our stock price and we do not time the release of MNPI based on equity grant dates.

During 2025, no stock option grants were made to any of our named executive officers during any period beginning four business days before the filing or furnishing of a periodic report or current report (other than a current report on Form 8-K disclosing a material new option award grant under Item 5.02(e) of that form) and ending one business day after the filing or furnishing of any such report with the SEC.

#### Summary Description of Our Equity Plans

#### TuHURA (f/k/a Morphogenesis, Inc.) 2019 Amended and Restated Equity Incentive Plan
The 2019 Plan was approved by the Legacy TuHURA board of directors and its stockholders in January 2019. The 2019 Plan, which amended and restated the TuHURA 2016 Stock Option Plan, provided for the issuance of up to 20,000,000 shares of Legacy TuHURA common stock, which includes the number of outstanding awards made pursuant to the TuHURA 2016 Stock Option Plan. The 2019 Plan allowed for awards of incentive stock options to TuHURA's employees, nonqualified stock options to TuHURA's directors, restricted stock, restricted stock units, and other stock-based awards. In connection with the closing of the Kintara Merger, TuHURA (f/k/a Kintara Therapeutics, Inc.) assumed all outstanding awards under the 2019 Plan. No further grants will be made under the 2019 Plan.

#### 2024 Equity Incentive Plan
In connection with the Kintara Merger, our Board of Directors approved the 2024 Plan on August 7, 2024, which was subsequently approved at an annual meeting of our stockholders held on October 4, 2024. The 2024 Plan replaced the Kintara Therapeutics, Inc. 2017 Omnibus Equity Incentive Plan, as amended (the "Legacy Kintara Plan"), under which no further grants will be made. The following is a summary of certain terms and conditions of the 2024 Plan.

Administration. Our Board of Directors or the Compensation Committee of the Board of Directors, or any successor committee with similar authority that our board of directors may appoint, (the "Committee") will administer the 2024 Plan (the "Administrator"). The 2024 Plan authorizes the Administrator to interpret the provisions of the 2024 Plan and award agreements; prescribe, amend and rescind rules and regulations relating to the 2024 Plan; correct any defect, supply any omission, or reconcile any inconsistency in the 2024 Plan, any award or any agreement covering an award; and make all other determinations necessary or advisable for the administration of the 2024 Plan, in each case in its sole discretion.

Eligibility. The Administrator may designate any of the following as a participant from time to time, to the extent of the Administrator's authority: any officer or other employee of our company or our affiliates; any individual who we or one of our affiliates has engaged to become an officer or employee; any consultant or advisor who provides services to our company or our affiliates; or any director, including a non-employee director.

Types of Awards. The 2024 Plan permits the grant of stock options (including incentive stock options), stock appreciation rights, performance shares, performance units, restricted stock, restricted stock units, cash incentives and other types of awards authorized under the 2024 Plan. These award types are described in further detail below.

Stock Subject to the 2024 Plan. The 2024 Plan provides that 11,000,000 shares of our common stock are reserved for issuance under the 2024 Plan, all of which may be issued pursuant to the exercise of incentive stock options. The aggregate number of shares of common stock reserved for issuance under the 2024 Plan increases annually on the first day of each fiscal year after the consummation of the Kintara Merger, commencing on the first day of our fiscal year 2025 and with a final increase on the first day of the 2034 fiscal year, by a number of shares of common stock ("Evergreen Shares") equal to the lesser of: (i) 5.0% of the outstanding shares of all classes of our common stock as of the last day of the immediately preceding fiscal year or (ii) such other number of shares (which may be zero) as our board of directors may determine. Evergreen Shares may not be issued pursuant to the exercise of incentive stock options. The number of shares reserved for issuance under the 2024 Plan increased by 2,116,187 Evergreen Shares on January 1, 2025 and an additional 2,996,828 Evergreen Shares on January 1, 2026.

The number of shares reserved under the 2024 Plan will be depleted on the date of the grant of an award by the maximum number of shares, if any, with respect to which such award is granted. An award that may be settled solely in cash shall not cause any depletion of the 2024 Plan's share reserve at the time such award is granted. In general, if an award granted under the 2024 Plan lapses, expires, terminates or is canceled without the issuance of shares under the award, if it is determined during or at the conclusion of the term of an award that all or some portion of the shares under the award will not be issuable on the basis that the conditions for such issuance will not be satisfied, if shares are forfeited under an award or if shares are issued under any award and we reacquire them pursuant to rights reserved upon the issuance of the shares, then such shares will again be available for issuance under the 2024 Plan, except that shares reacquired pursuant to reserved rights may not be issued pursuant to incentive stock options. Shares of common stock not issued or delivered as a result of the net settlement of an outstanding option or stock appreciation right, shares tendered or withheld in payment of the exercise price of an option, shares tendered or withheld to satisfy tax withholding obligations and shares purchased by us using proceeds from option exercises may not be re-credited to the reserve.

------

#### **Table of Contents**
Director Award Limit. The maximum number of shares that may be subject to awards granted during a single fiscal year to any individual non-employee director, subject to appropriate adjustments in accordance with the 2024 Plan, may not exceed the number of shares that has a grant date fair value of, when added to any cash compensation received by such non-employee director, $1,000,000, except that such limit will be $2,000,000 for the first fiscal year that the non-employee director serves on the board.

Options. The Administrator will generally determine all terms and conditions of each option. However, the grant date may not be any day prior to the date that the Administrator approves the grant, the exercise price may not be less than the fair market value of the shares subject to the option as determined on the date of grant (110% of the fair market value in the case of an incentive stock option granted to a 10% stockholder) and the option must terminate no later than ten years after the date of grant (five years in the case of an incentive stock option granted to a 10% stockholder). If a participant disposes of shares issued pursuant to the exercise of an incentive stock option under the circumstances described in Code Section 421(b) (relating to certain disqualifying dispositions), that participant must notify us of such disposition within 10 days. To the extent previously approved by the Administrator (in an award agreement or in administrative rules), and subject to such procedures as the Administrator may specify, the payment of the exercise price of options may be made by payment in cash or previously owned shares, through a broker-dealer assisted sell-to-cover transaction, by withholding shares otherwise deliverable upon exercise, or a combination of the foregoing. Except to the extent otherwise set forth in an award agreement, a participant will have no rights as a holder of common stock as a result of the grant of an option until the option is exercised, the exercise price and applicable withholding taxes are paid and the shares subject to the option are issued thereunder.

Stock Appreciation Rights. The Administrator will generally determine all terms and conditions of each stock appreciation right. A stock appreciation right is the right of a participant to receive cash in an amount, and/or common stock with a fair market value, equal to the appreciation of the fair market value of a share of common stock during a specified period of time. However, the grant date may not be any day prior to the date that the Administrator approves the grant, the grant price may not be less than the fair market value of the shares subject to the stock appreciation right as determined on the date of grant and the stock appreciation right must terminate no later than ten years after the date of grant.

Performance and Stock Awards. The Administrator will generally determine all terms and conditions of each award of shares, restricted stock, restricted stock units, performance shares or performance units. Restricted stock means shares of common stock that are subject to a risk of forfeiture, restrictions on transfer or both a risk of forfeiture and restrictions on transfer. A restricted stock unit means the right to receive a payment equal to the fair market value of one share of common stock. Performance shares means the right to receive shares of common stock, including restricted stock, to the extent performance goals are achieved (or other requirements are met). A performance unit means the right to receive a cash payment or shares valued in relation to a unit that has a designated dollar value or the value of which is equal to the fair market value of one or more shares of common stock, to the extent performance goals are achieved (or other requirements are met). The Administrator will determine the length of the vesting and/or performance period.

Any participant who holds restricted stock has the right to vote their shares, unless the Administrator provides otherwise. Any participant who holds other types of awards does not have any rights as a stockholder of our company, unless the Administrator provides otherwise.

Cash Incentive Awards. The Administrator has the authority to grant cash incentive awards. A cash incentive award is the right to receive a cash payment to the extent performance goals are achieved. The Administrator will determine all of the terms and conditions of each cash incentive award, including the performance goals, the performance period, the potential amount payable and the timing of payment.

------

Other Stock-Based Awards. The Administrator may grant a participant shares of unrestricted stock as a replacement for other compensation to which the participant is entitled, such as in payment of director fees, in lieu of cash compensation, in exchange for cancellation of compensation right or as a bonus.

Transferability of Awards. Awards under the 2024 Plan may not be sold, transferred for value, pledged, assigned, or otherwise alienated or hypothecated, other than by will or the laws of descent and distribution, unless and to the extent the Administrator allows a participant to: (1) designate in writing a beneficiary to exercise the award or receive payment under the award after the participant's death; (2) transfer an award to the former spouse of the participant as required by a domestic relations order incident to a divorce; or (3) transfer an award (provided the participant may not receive consideration for such transfer), provided that in each case, the assignee cannot further transfer the award. Any permitted transfer shall be subject to compliance with applicable securities laws.

Adjustments.

Under the terms of the 2024 Plan, if any of the following occurs:

• we are involved in a merger or other transaction in which our common stock is changed or exchanged;

• we subdivide or combine our common stock or declare a dividend payable in our common stock, other securities or other property;

• we effect a cash dividend, the amount of which, on a per share basis, exceeds 10% of the fair market value of a share of stock at the time the dividend is declared, or we effect any other dividend or other distribution on our common stock in the form of cash, or a repurchase of shares of our common stock, that our board of directors determines is special or extraordinary in nature or that is in connection with a transaction that we characterize publicly as a recapitalization or reorganization involving our common stock; or

• Any other event occurs, which, in the judgment of our board of directors or committee thereof, necessitates an adjustment to prevent an increase or decrease in the benefits or potential benefits intended to be made available under the 2024 Plan; then the Administrator will, in a manner it deems equitable to prevent an increase or decrease in the benefits or potential benefits intended to be made available under the 2024 Plan and subject to certain provisions of the Code, adjust the number and type of shares of common stock subject to the 2024 Plan and which may, after the event, be made the subject of awards; the number and type of shares of common stock subject to outstanding awards; the grant, purchase or exercise price with respect to any award; and performance goals of an award. The Administrator may also (or in lieu of the foregoing) make provision for a cash payment to the holder of an outstanding award in exchange for the cancellation of all or a portion of the award (without the consent of the holder of an award) in an amount determined by the Administrator effective at such time as the Administrator specifies (which may be the time such transaction or event is effective).

Repricing Prohibited. Neither the Administrator nor any other person may, without stockholder approval: (1) amend the terms of outstanding stock options or stock appreciation rights to reduce the exercise price of such outstanding stock options or stock appreciation rights; (2) cancel outstanding stock options or stock appreciation rights in exchange for stock options or stock appreciation rights with an exercise price that is less than the exercise price of the original stock options or stock appreciation rights; or (3) cancel outstanding stock options or stock appreciation rights with an exercise price above the current share price in exchange for cash or other securities.

Backdating Prohibited. The Administrator may not grant a stock option or stock appreciation right with a grant date that is effective prior to the date the Administrator takes action to approve such award.

Term of Plan. Unless our Board of Directors terminates the 2024 Plan on an earlier date, the 2024 Plan will terminate, and no further awards can be granted thereunder, after the 10th anniversary of the latest date on which the 2024 Plan, or any amendment thereto or restatement thereof, has been approved by our stockholders.

The Administrator may amend or terminate the 2024 Plan at any time, except that (1) our Board of Directors must approve any amendment that it is required to approve by reason of applicable law or prior action of our board, (2) stockholders must approve any amendments if such approval is required by any applicable law or the listing requirements of any principal securities exchange on which our shares are then traded, and (3) stockholders must approve any amendments that would diminish the backdating or repricing restrictions contained in the 2024 Plan.

Amendment, Modification, Cancellation and Disgorgement of Awards. Subject to exceptions specified in the 2024 Plan, the Administrator may amend or cancel an award granted under the 2024 Plan at any time, or waive any restrictions or conditions applicable to any award or the exercise of the award. In addition, the Administrator will have full power and authority to terminate or cause a participant to forfeit an award, and require the participant to disgorge any gains attributable to an award, if the participant engages in any action constituting, as determined by the Administrator in its discretion, cause for termination or a breach of a material policy, any award agreement or any other agreement concerning noncompetition, nonsolicitation, confidentiality, trade secrets, intellectual property, nondisparagement or similar obligations. All awards, and any shares issued or cash paid pursuant to an award, are also subject to any applicable recoupment or clawback policy adopted by us or any recoupment or similar requirement contained in applicable law, regulation or the listing requirements of the exchange or system on which our stock is principally traded.

#### Policies and Practices Related to the Timing of Grants of Certain Equity Awards
We generally grant annual equity-based awards during the first half of our fiscal year, although such timing may change from year to year. Our Compensation Committee also may consider and approve interim or mid-year grants, or grants made on another basis, from time to time based on business needs, changing compensation practices or other factors, in the discretion of our Compensation Committee.

Our Compensation Committee does not take into account material nonpublic information in determining the timing and terms of equity-based awards, and we have not timed the disclosure of material nonpublic information for the purpose of affecting the value of executive compensation.

#### DIRECTOR COMPENSATION
The following table presents the total compensation for each person who served as a non-employee member of our board of directors and received compensation for such service during the fiscal year ended December 31, 2025. Dr. James Bianco, our Chief Executive Officer, did not receive any compensation for his service as a member of our Board of Directors for the fiscal year ended December 31, 2025. Dr. Bianco's compensation for service as an employee for fiscal year 2025 is presented in the section titled "Executive Compensation—Summary Compensation Table" above.

#### Non-Employee Director Compensation Program
The following describes the material terms of our Non-Employee Director Compensation Program (the "Program"), as adopted by our Board of Directors effective January 1, 2025. The Program provides for both cash retainers and equity-based compensation payable to each member of our board who is not an employee of the Company or any parent or subsidiary of the Company. Cash and equity compensation under the Program is paid or granted automatically without further board of director action, unless a non-employee director declines receipt by written notice to the Company. The Board of Directors may amend, modify, or terminate the Program at any time in its sole discretion.

------

#### Cash Compensation
Beginning January 1, 2025, each non-employee director is entitled to receive the following annual cash retainers:

Each non-employee director receives an annual retainer of $40,000 for service on our Board of Directors, except that the Chair of the Board receives an annual retainer of $70,000. In addition, non-employee directors serving on standing committees of our Board of Directors receive the following additional annual retainers for their committee service:

---

| | | |
|:---|:---|:---|
| **Committee** | **Chairperson<br>Retainer** | **Member<br>Retainer** |
|  Audit Committee | $15000 | $7500 |
|  Compensation Committee | $11000 | $6000 |
|  Nominating and Corporate Governance Committee | $10000 | $5000 |

---

All annual retainers are earned on a quarterly basis based on a calendar quarter and are paid by the Company in arrears not later than the fifteenth day following the end of each calendar quarter. In the event a non-employee director does not serve for an entire calendar quarter, the retainer is prorated for the portion of the quarter actually served.

#### Equity Compensation
Under the Program, each non-employee director who is serving on our Board of Directors as of the first business day of January each year is automatically granted stock options to purchase shares of the Company's common stock under the 2024 Plan or any other applicable equity incentive plan then maintained by the Company. The number of stock options granted is determined by dividing (A) $185,000 (or $215,000 in the case of the Chair of the Board) by (B) the Black-Scholes value of the right to purchase one share of our common stock on the date of grant, using the assumptions employed by the Company for financial statement purposes and the closing price per share on the date of grant.

Each annual option award vests in three equal installments on the first three anniversaries of the date of grant, subject to the non-employee director's continued service on our Board of Directors through each applicable vesting date. Unless the board of directors otherwise determines, no unvested portion of an award will vest following a non-employee director's termination of service. Notwithstanding the foregoing, all outstanding equity awards held by a non-employee director become fully vested upon the director's death or disability, or upon a Change of Control (as defined in the 2024 Plan).

Our Board of Directors retains discretion to determine that future awards may be granted, in whole or in part, in the form of alternative equity awards permitted under the 2024 Plan, such as restricted stock. All grants under the Program are subject to the terms and provisions of the 2024 Plan and the applicable award agreements.

As of December 31, 2025, each of our non-employee directors held the following outstanding options:

---

| | | |
|:---|:---|:---|
| **Name** | **Shares<br>Subject to<br>Outstanding<br>Options** | **Shares<br>Subject to<br>Outstanding<br>Options** |

#### PROPOSAL 2: THE NASDAQ PROPOSAL

#### Overview
As may be required by Nasdaq Listing Rule 5635(d), we are asking that our stockholders approve the issuance of an aggregate of 1,878,287 shares of our common stock (the "Loan Fee Shares") to Parkview Holdings One LLC ("Parkview"), an affiliate of K&V Investment One LLC ("K&V Investment"), our largest stockholder (both entities are affiliated with Mr. Vijay Patel), pursuant to that certain Fee Letter, dated as of April 21, 2026, between us and Parkview and made in connection with our revolving credit facility with Parkview. The number of Loan Fee Shares issuable to Parkview is based on a price per share equal to $2.662, which is the average of the daily closing prices of our common stock during the ten trading days ending on (and including) April 21, 2026. Pursuant to Nasdaq Listing Rule 5635(d), the issuance of the Loan Fee Shares may be deemed to be aggregated with the securities issued to K&V Investment in our registered direct offering that closed in December 2025 (the "December 2025 Offering"). This aggregation means the combined issuances exceed the 20% threshold under Nasdaq Listing Rule 5635(d), requiring stockholder approval prior to the issuance of the Loan Fee Shares to Parkview.

#### Nasdaq Listing Rule 5635(d)
As a result of being listed for trading on the Nasdaq Stock Market, issuances of our common stock are subject to the Nasdaq Listing Rules, including Nasdaq Listing Rule 5635(d). Nasdaq Listing Rule 5635(d) requires stockholder approval in connection with a transaction or series of transactions, other than a public offering, involving the sale, issuance or potential issuance by the issuer of common stock (or securities convertible into or exercisable for common stock) equal to 20% or more of the common stock or 20% or more of the voting power outstanding before the issuance for a price that is less than the lower of (i) the Nasdaq closing price immediately preceding the signing of the binding agreement, or (ii) the average of the Nasdaq closing price for the five trading days immediately preceding the signing of the binding agreement.

Under Nasdaq Listing Rules, Nasdaq may aggregate transactions to determine whether stockholder approval is required. If Nasdaq aggregated the shares issuable to Parkview pursuant to the Fee Letter with the securities issued to K&V Investment in the December 2025 Offering, such issuance would result in the issuance of more than 20% of our common stock or more than 20% of the voting power outstanding before the issuance for a price that is lower than the lower of (i) the Nasdaq closing price immediately preceding the signing of the binding agreement, or (ii) the average of the Nasdaq closing price for the five trading days immediately preceding the signing of the binding agreement.

#### Background
*December 2025 Offering* 

On December 9, 2025, we entered into a securities purchase agreement (the "Purchase Agreement") with certain investors (collectively, the "Purchasers"), including K&V Investment. The Purchase Agreement was entered into in connection with the sale and issuance in a registered direct offering of: (i) 9,462,423 shares of our common stock, (ii) Series A common stock purchase warrants to purchase up to 9,462,423 shares of common stock (the "Series A Warrants"), and (iii) Series B common stock purchase warrants to purchase up to 9,462,423 shares of common stock (the "Series B Warrants," and together with the Series A Warrants, the "Common Warrants"). The offering price for each share and accompanying Series A Warrant and Series B Warrant was $1.65. Each Common Warrant has an exercise price of $1.95 per share and is exercisable beginning six months after the date of issuance.

On the same date, we entered into a side letter to the Purchase Agreement (the "Side Letter") with K&V Investment whereby we agreed that, for purposes of K&V Investment's funding requirements under the Purchase Agreement, K&V Investment was to fund (i) with respect to $5 million of K&V Investment's subscription

------

amount, at a date chosen by K&V Investment that was no later than January 30, 2026 (the "Second Closing"), and (ii) with respect to $2 million of K&V Investment's subscription amount, at a date chosen by K&V Investment that was no later than February 27, 2026 (the "Third Closing"). We issued to K&V Investment the shares of common stock and Common Warrants purchased at each of the Second Closing and Third Closing following receipt of consideration thereof, with such issued Common Warrants exercisable six months following the date of the Second Closing and the date of the Third Closing, respectively, and expiring on the same date as the Common Warrants issued to the other Purchasers on December 10, 2025, the first closing date (the "First Closing").

Pursuant to the terms of the Purchase Agreement and the Side Letter, the closing of the December 2025 Offering occurred in three tranches. At the First Closing, we issued an aggregate of 5,219,999 shares of common stock, Series A Warrants to purchase up to an aggregate of 5,219,999 shares of common stock and Series B Warrants to purchase up to an aggregate of 5,219,999 shares of common stock. At the Second Closing, we issued to K&V Investment an aggregate of 3,030,303 shares of common stock, Series A Warrants to purchase up to an aggregate of 3,030,303 shares of common stock and Series B Warrants to purchase up to an aggregate of 3,030,303 shares of common stock. At the Third Closing, we issued to K&V Investment an aggregate of 1,212,121 shares of common stock, Series A Warrants to purchase up to an aggregate of 1,212,121 shares of common stock and Series B Warrants to purchase up to an aggregate of 1,212,121 shares of common stock. The Series A Warrants expire five and one-half years from the date of the First Closing and the Series B Warrants expire twenty-four months from the date of the First Closing.

Because K&V Investment is an affiliate of Parkview, Nasdaq may aggregate the issuance of the Loan Fee Shares under the Fee Letter with securities issued to K&V Investment in the December 2025 Offering for purposes of Nasdaq Listing Rule 5635(d).

*April 2026 Revolving Credit Facility* 

On April 21, 2026, we entered into a Loan Agreement (the "Loan Agreement") with Parkview, providing for a $50 million secured revolving credit facility maturing April 21, 2031. Borrowings under the Loan Agreement bear interest at 12% per annum (18% during an event of default), payable monthly in arrears. The Company intends to use borrowings for general corporate purposes, including funding its clinical trials and development programs. Assuming stockholder approval as set forth in this proposal of the Loan Fee Shares, we expect the facility will fund operations into the first quarter of 2028.

Under the Loan Agreement, we have also agreed to:

• pursuant to the Fee Letter, pay a one-time commitment fee of $5.0 million (10% of the total commitment), payable through the issuance of 1,878,287 shares of common stock to Parkview, subject to stockholder approval. If the issuance of the Loan Fee Shares is not approved by our stockholders by August 31, 2026, the fee is payable in cash;

• pay an annual cash facility fee, payable annually beginning on the first anniversary of the date of the Loan Agreement, equal to one and one-half percent (1.5%) of the total commitment; and

• enter into two Warrant Amendment Agreements (the "Warrant Amendment Agreements") extending to April 21, 2031 the exercise period for 4,364,873 warrants held by K&V Investment (at exercise prices of $3.69 and $5.70 per share).

The Loan Agreement contains customary restrictive covenants and events of default (including a Change of Control (acquisition of 51% or more of the Company by a third party other than Parkview or its affiliates) or discontinuance of the IFx-2.0 program), upon which Parkview may accelerate outstanding obligations. We may prepay without penalty and terminate or reduce the commitment at any time.

------

The Loan Agreement is not convertible into equity except upon a Change of Control in which case Parkview may convert outstanding principal and interest into shares of our common stock at $2.662 per share, subject to prior stockholder approval. Parkview also has the right, upon request, to appoint one director to our Board of Directors.

In connection with the Loan Agreement, we also entered into a Royalty Agreement, dated April 21, 2026 (the "Royalty Agreement"), granting Parkview an annual royalty in the low to mid-single digits on net sales of products based on our IFx-2.0 intellectual property, continuing through the last-to-expire patent covering IFx-2.0.

#### Stockholder Approval Requirement
As noted above, because the Loan Fee Shares are issuable to Parkview, an affiliate of K&V Investment (both entities are affiliated with Mr. Vijay Patel), Nasdaq may require that the issuance of the Loan Fee Shares under the Fee Letter be aggregated with the securities issued to K&V Investment in the December 2025 Offering as a series of related transactions for purposes of determining compliance with Nasdaq Listing Rule 5635(d).

Because our common stock is listed on the Nasdaq, we are subject to Nasdaq's rules and regulations. Pursuant to Nasdaq Listing Rule 5635(d), stockholder approval is required prior to a 20% Issuance at a price that is less than the Minimum Price. Nasdaq may aggregate multiple issuances as a series of related transactions for purposes of Nasdaq Listing Rule 5635(d), considering factors such as the timing of the issuances, whether the transactions were negotiated at the same time or with the same parties, whether the issuances involve the same or affiliated investors, and whether the issuances were made pursuant to the same or related agreements. Here, because K&V Investment and Parkview are affiliates and under the same beneficial ownership, the securities issued to K&V Investment in the December 2025 Offering and the Loan Fee Shares issuable to Parkview under the Fee Letter may be required to be aggregated as a series of related transactions under Nasdaq Listing Rule 5635(d).

For purposes of Nasdaq Listing Rule 5635(d), (A) "20% Issuance" means a transaction, other than a public offering, involving the sale, issuance or potential issuance by us of common stock (or securities convertible into or exercisable for common stock), which alone or together with sales by our officers, directors, or substantial stockholders equals 20% or more of common stock (which for purposes of this calculation, includes issued and outstanding shares of our voting common stock and non-voting common stock) or 20% or more of the voting power outstanding before the issuance and (B) "Minimum Price" means a price that is the lower of: (i) the closing price (as reflected on Nasdaq.com) immediately preceding the signing of the binding agreement; or (ii) the average closing price of common stock (as reflected on Nasdaq.com) for the five trading days immediately preceding the signing of the binding agreement. Because the combined issuances to K&V Investment and Parkview, when aggregated as a series of related transactions, exceed the 20% threshold under Nasdaq Listing Rule 5635(d), stockholder approval is required prior to the issuance of the Loan Fee Shares. Stockholder approval of this proposal will constitute stockholder approval for purposes of Nasdaq Listing Rule 5635(d).

#### Reasons for Transaction and Effect on Current Stockholders
Our Board of Directors has determined that the Loan Agreement and the Fee Letter, with such modifications, amendments, or changes (consistent with the intent and purpose of this proposal) agreed upon by the parties thereto, and in accordance with the stockholder approval requirements of Nasdaq Listing Rule 5635(d), are in the best interests of us and our stockholders because the Loan Agreement provides the Company with a $50 million revolving credit facility to fund the Company's ongoing clinical trials, development programs and general corporate purposes. Without the successful approval of this proposal, we will be obligated to pay to Parkview a non-refundable closing fee under the Loan Agreement in an amount equal to $5.0 million, an amount equal to 10% of the aggregate principal amount as of the closing date.

------

#### Potential Adverse Effects—Dilution and Impact on Existing Stockholders
The issuance of the Loan Fee Shares will have a dilutive effect on current stockholders in that the percentage ownership of our company held by such current stockholders will decline as a result of the issuance of such shares. This means also that our current stockholders will hold a smaller interest in us as a result of the issuance of the Loan Fee Shares and therefore have less ability to influence significant corporate decisions requiring stockholder approval. Issuance of the Loan Fee Shares could also have a dilutive effect on the book value per share and any future earnings per share. Dilution of equity interests could also cause prevailing market prices for our common stock to decline.

If the Loan Fee Shares are issued in full, a total of 1,878,287 shares of common stock will be issuable to Parkview within three business days following the approval of this proposal.

#### Board Recommendation
The Board of Directors unanimously recommends a vote FOR the approval of the issuance of the Loan Fee Shares to Parkview pursuant to the terms of the Fee Letter, with such modifications, amendments, or changes (consistent with the intent and purpose of this proposal) agreed upon by the parties to the Fee Letter, and in accordance with the stockholder approval requirements of Nasdaq Listing Rule 5635(d).

Without the successful approval of this proposal, we will be required to pay to Parkview a non-refundable closing fee in an aggregate amount equal to $5.0 million under the Loan Agreement. This closing fee represents 10% of the aggregate principal amount as of the closing date and would constitute a significant cash outlay without any corresponding benefit to stockholders.

In addition to avoiding this substantial closing fee, the Board of Directors believes that approval of this proposal is in the best interests of stockholders for the following reasons:

• The Loan Agreement provides us with a $50 million revolving credit facility, which is critical to funding our ongoing clinical trials, development programs, and general corporate purposes;

• Access to this credit facility enhances our financial flexibility and runway, allowing management to pursue strategic opportunities and advance our pipeline without the need to seek alternative, potentially more dilutive or costly financing arrangements;

• The issuance of the Loan Fee Shares to Parkview aligns the interests of Parkview with those of our other stockholders as a significant equity holder; and

• The terms of the Loan Agreement and Fee Letter were negotiated at arm's length and the Board of Directors believes they are reasonable and in our best interests and those of our stockholders.

#### THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS VOTE "FOR" THE NASDAQ LISTING RULE 5635(d) PROPOSAL (PROPOSAL TWO)

------

#### PROPOSAL 3: ADVISORY VOTE ON EXECUTIVE COMPENSATION
In accordance with Section 14A of the Securities Exchange Act, and the Dodd-Frank Act, we are asking our stockholders to vote, on a non-binding advisory basis, on the approval of the compensation of our named executive officers as disclosed in this proxy statement.

Our Board of Directors and our Compensation Committee believes that our compensation policies and practices are effective in achieving our goals of motivating and retaining our executives by motivating and rewarding excellence in individual and company performance and aligning our executives' interests with those of our stockholders. Please read the section of this proxy statement titled "Executive Compensation" for additional details about the executive compensation programs, including information about the fiscal year 2025 compensation of our named executive officers.

The Executive Compensation Proposal is advisory and non-binding on the Board of Directors. However, the Board of Directors and our Compensation Committee will review and consider the results of this vote when evaluating our executive compensation program. This proposal, commonly known as a "say-on-pay" proposal, gives our stockholders the opportunity to express their views on our named executive officers' compensation. We previously solicited the vote, and received the approval of our stockholders in excess of the majority of the total votes cast at our special meeting in lieu of annual meeting held in 2025 (the "Special Meeting"), of our stockholders for the approval of our executive officer's compensation during the Special Meeting and are soliciting the vote of our stockholders, on an advisory basis, in connection with the Annual Meeting. At the Annual Meeting, we will therefore ask our stockholders to adopt the following resolution:

"RESOLVED, that the compensation of TuHURA's named executive officers, as such compensation is disclosed in TuHURA's proxy statement for TuHURA's 2026 Annual Meeting of the stockholders pursuant to Item 402 of Regulation S-K is hereby APPROVED on a non-binding, advisory basis."

The say-on-pay vote is advisory, and therefore not binding on us, our Compensation Committee or the Board of Directors. The Board of Directors and our Compensation Committee value the opinions of its stockholders and, to the extent there is any significant vote against named executive officers compensation as disclosed in this proxy statement, we will consider its stockholders' concerns and the Compensation Committee will evaluate whether any actions are necessary to address those concerns.

#### Approval Required
Approval of the Executive Compensation Proposal requires the affirmative vote of a majority of the total votes cast at the Annual Meeting. As a result, abstentions, broker non-votes, if any, and any other failure to submit a proxy or vote in person at the meeting will not affect the outcome of the vote of the Executive Compensation Proposal.

#### THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE "FOR" THE APPROVAL, ON AN ADVISORY BASIS, OF THE EXECUTIVE COMPENSATION PROPOSAL (PROPOSAL 3).

------

#### PROPOSAL 4: ADVISORY VOTE ON THE FREQUENCY OF FUTURE ADVISORY VOTES ON EXECUTIVE COMPENSATION
In connection with the enactment of the Dodd-Frank Wall Street Reform and Consumer Protection Act ("Dodd-Frank"), we are required to seek a stockholder advisory vote on executive compensation (commonly referred to as "say-on-pay") every one, two or three years.

After careful consideration, our Board of Directors has concluded that providing stockholders with an advisory vote on executive compensation every three years is the most appropriate policy for us at this time and recommends stockholders vote for future advisory votes on executive compensation to occur every three years. Voting every three years, rather than every one or two years, will provide stockholders with the opportunity to conduct thoughtful analyses of our compensation program over a period of time in relation to our long-term performance as our compensation program does not change significantly from year to year. A triennial vote cycle will provide stockholders with a more complete view of the amount and mix of components of the compensation paid to our named executive officers. A triennial vote will also provide us with sufficient time to evaluate and respond effectively to stockholder input, engage with stockholders to understand and respond to prior voting results and implement any appropriate changes to our program. In addition, a triennial vote will provide time to evaluate the effectiveness of our compensation program and any changes made to the program.

This advisory vote on the frequency of future advisory votes on executive compensation is non-binding on the board of directors. Stockholders will be able to specify one of four choices for this proposal on the proxy card: one year, two years, three years or abstain. Stockholders are not voting to approve or disapprove the Board of Directors' recommendation. Although non-binding, the Board of Directors and the Compensation Committee will carefully review the voting results. Notwithstanding the Board of Directors' recommendation and the outcome of the stockholder vote, the Board of Directors may in the future decide to conduct advisory votes on a more frequent basis and may vary its practice based on factors such as discussions with stockholders and the adoption of material changes to compensation programs.

#### THE BOARD OF DIRECTORS RECOMMENDS THAT STOCKHOLDERS VOTE TO CONDUCT FUTURE ADVISORY VOTES ON EXECUTIVE COMPENSATION EVERY THREE YEARS.

------

#### PROPOSAL 5: AUDITOR RATIFICATION PROPOSAL

#### Independent Registered Public Accounting Firm
Our stockholders are being asked to ratify the appointment by our Audit Committee of Cherry Bekaert LLP, or Cherry Bekaert, as our independent registered public accounting firm for the fiscal year ending December 31, 2026. Marcum LLP, or Marcum, served as the independent registered public accounting firm for the Company prior to the completion of the Kintara Merger. Marcum was informed that it would be replaced by Cherry Bekaert as our independent registered public accounting firm following the completion of the Kintara Merger. Cherry Bekaert has served as the independent registered public accounting firm of Legacy TuHURA since 2018.

We are not required to seek stockholder approval for the appointment of our independent registered public accounting firm, however, our Audit Committee and the Board of Directors believe it is sound corporate practice to seek such approval. If the appointment is not ratified, our Audit Committee will investigate the reasons for stockholder rejection and will re-consider the appointment. Even if the selection is ratified, our Audit Committee in its discretion may direct the appointment of a different independent registered public accounting firm at any time during the year if it determines that such change would be in the best interests of us and our stockholders.

#### Attendance at Annual Meeting
Representatives of Cherry Bekaert are expected at the Annual Meeting and will have the opportunity to make a statement if they desire to do so and be available to respond to appropriate questions from stockholders submitted in writing in accordance with the Annual Meeting procedures.

#### Principal Accountant Fees and Services
The following table provides information regarding the aggregate fees paid to Cherry Bekaert in connection with their audit of our consolidated financial statements and for other services provided during the period following the closing of the Kintara Merger and for the years ended December 31, 2025 and 2024. For a summary of the audit fees paid by Kintara for the fiscal year ended June 30, 2024, see Kintara's Annual Report on Form 10-K filed with the SEC on October 7, 2024.

|:---|:---|:---|
|  | **Year Ended<br>December 31,<br>2025** | **Year Ended<br>December 31,<br>2024** |
|  Audit fees | $243075 | $193200 |
|  Tax fees | $16634 | $30953 |
|  All other fees | $— | $— |
|  Total fees | $259709 | $224153 |

---

*Audit fees*. Audit fees consist of fees for the audit of our annual financial statements, review of interim financial statements included in our quarterly reports on Form 10-Q, registration statements on Form S-4, registration statements on Form S-8 and other professional services provided in connection with financings and other regulatory filings.

*Tax Fees*. Tax fees consist of fees for professional services, including tax compliance, advice and tax planning.

*All other fees*. All other fees consist of work performed by Cherry Bekaert that does not meet the above category descriptions.

------

#### Audit Committee Pre-Approval Policy
In accordance with applicable laws, rules and regulations, our Audit Committee charter and pre-approval policies established by our Audit Committee require that the Audit Committee review in advance and pre-approve all audit and permitted non-audit fees for services provided to us by our independent registered public accounting firm. The services performed by, and the fees to be paid to, Cherry Bekaert for the years ending December 31, 2025 and 2024 were approved by our Audit Committee.

#### Approval Required
The approval of the Auditor Ratification Proposal will require the affirmative vote of a majority of the total votes cast at the Annual Meeting. As a result, abstentions, broker non-votes, if any, and any other failure to submit a proxy or vote in person at the meeting will not affect the outcome of the vote of this proposal.

**THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE "FOR" THE RATIFICATION OF THE APPOINTMENT OF CHERRY BEKAERT LLP AS THE COMPANY'S INDEPENDENT REGISTERED ACCOUNTING FIRM FOR THE YEAR ENDING DECEMBER 31, 2026 (PROPOSAL 5).** 

------

#### PROPOSAL 6: ADJOURNMENT OF THE ANNUAL MEETING
The Annual Meeting may be adjourned to another time and place if necessary to solicit additional proxies if there are insufficient shares of our common stock represented (either in person or by proxy) and voting in order to approve Proposal 2 (the Nasdaq Proposal) or to constitute a quorum necessary to conduct the business of the Annual Meeting.

In the Adjournment Proposal, we are asking stockholders to authorize the holder of any proxy solicited by the Board of Directors to vote in favor of adjourning or postponing the Annual Meeting or any adjournment or postponement thereof. If our stockholders approve this proposal, we could adjourn or postpone the Annual Meeting, and any adjourned session of the Annual Meeting, to use the additional time to solicit additional proxies in favor of the Nasdaq Proposal.

Additionally, approval of the Adjournment Proposal could mean that, in the event we receive proxies indicating that a majority of the outstanding shares of our common stock will vote against the Nasdaq Proposal, we could adjourn or postpone the Annual Meeting without a vote on the Nasdaq Proposal and use the additional time to solicit the holders of those shares to change their vote in favor of the Nasdaq Proposal.

If it is necessary or appropriate (as determined in good faith by the Board of Directors) to adjourn the Annual Meeting, no notice of the adjourned meeting is required to be given to our stockholders, other than an announcement at the Annual Meeting of the time and place to which the Annual Meeting is adjourned, so long as the meeting is adjourned for 30 days or less and no new Record Date is fixed for the adjourned meeting. At the adjourned meeting, we may transact any business which might have been transacted at the original meeting.

#### Vote Required for Approval
Whether or not there is a quorum, the approval of the Adjournment Proposal requires the affirmative vote of a majority of the votes cast at the Annual Meeting on this proposal (meaning the number of votes cast at the Annual Meeting "**FOR**" the Adjournment Proposal must exceed votes cast "**AGAINST**" in order for the Adjournment Proposal to be approved). A failure to vote, a broker non-vote or an abstention will have no effect on the outcome of the Adjournment Proposal.

#### THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE "FOR" THE ADJOURNMENT PROPOSAL (PROPOSAL 6).

#### SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT<sup>3</sup>
To our knowledge, the following table sets forth certain information regarding the beneficial ownership of our common stock as of the Record Date of June 26, 2026 by:

• all persons known by us to own beneficially 5% or more of our common stock;

• each member of our board of directors;

• each of our named executive officers; and

• all members of our board of directors and executive officers as a group.

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

The table lists applicable percentage ownership based on 63,682,528 shares of common stock outstanding as of the Record Date. The number of shares beneficially owned includes shares of common stock that each person has the right to acquire within 60 days of the Record Date, including upon the exercise of stock options, warrants and the settlement of restricted stock units. These stock options, warrants and restricted stock units shall be deemed to be outstanding for the purpose of computing the percentage of outstanding shares of common stock owned by such person but shall not be deemed to be outstanding for the purpose of computing the percentage of outstanding shares of common stock owned by any other person.

This table is based upon information supplied by our officers, directors as of the record date and the principal stockholders and Schedules 13D and 13G filed with the SEC.

Pursuant to the Loan Agreement, Parkview agreed to extend a $50 million revolving credit facility to us, maturing on April 21, 2031, to fund general corporate purposes, including clinical trials and development programs. Borrowings are secured by substantially all of our assets and the assets of our subsidiaries and bear interest at 12% per annum (plus an additional 6% during any event of default), payable monthly in arrears.

On December 9, 2025 (the "First Closing"), the Company and K&V Investment entered into a Securities Purchase Agreement whereby (the "Securities Purchase Agreement") K&V Investment agreed to purchase $7 million (the "Subscription Amount") for the issuance of an aggregate of 9,462,423 shares of common stock (the "K&V Shares"), 9,462,423 series A common stock purchase warrants (the "Series A Warrants") and 9,462,423 series B common stock purchase warrants (the "Series B Warrants"). On the same date, the Company and K&V Investment entered into a Side Letter to the Securities Purchase Agreement (the "Side Letter") whereby the Company and K&V Investment agreed that K&V Investment would fund and purchase such securities (i) with respect to $5 million of the Subscription Amount, on a date chosen by K&V Investment to be no later than January 30, 2026 and (the "Second Closing") and (ii) with respect to $2 million of the Subscription Amount, at a date chosen by K&V Investment no later than February 27, 2026 (the "Third Closing").

Pursuant to the terms of the Nachtrab Loan Agreement, the Lender agreed to make loans to us in an aggregate principal amount of up to $3.0 million (the "Loans") during a 30-day availability period beginning on the date of the Nachtrab Loan Agreement (the "Availability Period").

Following the execution of the Amendment, on December 2, 2025, we borrowed an additional $1.5 million from the Lender under the Nachtrab Loan Agreement (the "Second Loan"), which resulted in aggregate Loans of $3.0 million made to us under the Nachtrab Loan Agreement.

Approximately $3.7 million of the offering (the "Final Tranche Offering Amount") was agreed to be purchased and funded by December 31, 2025 by the Deferral Investors, who agreed to defer the purchase of a portion of their subscribed shares of common stock and common stock purchase warrants.

Our audited financial statements for the fiscal year ended December 31, 2025 and certain other related financial and business information are contained in our Annual Report on Form 10-K, which is being made available to TuHURA's stockholders along with this proxy statement, but which is not deemed a part of the proxy soliciting material.

#### Householding of Proxy Materials
SEC rules permit companies and intermediaries such as brokers to satisfy delivery requirements for proxy statements and notices with respect to two or more stockholders sharing the same address by delivering a single proxy statement or a single notice addressed to those stockholders. This process, which is commonly referred to as "householding," provides cost savings for companies. Some brokers household proxy materials, delivering a single proxy statement or notice 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 materials 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 proxy statement or notice, or if your household is receiving multiple copies of these documents and you wish to request that future deliveries be limited to a single copy, please notify your broker if shares are held in a brokerage account, or if you hold registered shares, for TuHURA stockholders, please call (813) 875-6600, or write to 10500 University Center Dr., Suite 110, Tampa, FL 33612.

Requests for additional copies of this proxy statement should be directed to: TuHURA Biosciences, Inc., 10500 University Center Dr., Suite 110, Tampa, FL 33612, Telephone (813) 875-6600.
