Dear James,

**Offer of Employment with Kazia Therapeutics**

On behalf of Kazia Therapeutics, Inc, I am pleased to offer you the position of **Chief Financial Officer**. We look forward to welcoming you as a colleague.

The terms of the position are as set forth below.

**Position**

<u>Particulars</u>. Your position, place of work, and commencement date will be as described in Attachment 1 of this letter.

<u>Employer</u>. Your employer will be Kazia Therapeutics, Inc (the "Company"), a Delaware company. Kazia reserves the right to assign your employment to other corporate entities within its group at its sole discretion.

During the term of your employment, you agree to devote your business time, attention, skill, and efforts to the business of the Company. All benefits, profits, results, and work product arising from or incident to your services shall belong exclusively to the Company. Except as expressly disclosed herein or approved in advance in writing by the Chief Executive Officer, you shall not render commercial or professional services of any nature to any other person or organization, whether or not for compensation, nor shall you directly or indirectly engage in or participate in any business that is competitive with the business of the Company. Nothing in this agreement shall prohibit you from accepting occasional speaking or presentation engagements for customary honoraria or from serving on the boards of charitable or non-profit organizations, provided such activities do not interfere with your duties to the Company.

<u>Travel and Expenses</u>. You acknowledge that the nature of the position may require frequent travel within and outside of the United States from time to time. The Company will make reasonable efforts to accommodate your circumstances and preferences in directing such travel. You will be entitled to reimbursement of reasonable and customary expenses incurred in carrying out the position, in accordance with the Company's policies, on submission of an expense report and valid receipts.

Adjustments to compensation will be at Kazia's sole discretion and are not guaranteed.

<u>Sole Consideration</u>. You acknowledge that the compensation described in Attachment 1 of this letter will be your only remuneration for your employment with the company. Due to the senior nature of the position, you acknowledge that additional hours may be required from time to time and that no separate payment will be made for overtime. You may be requested to perform additional duties that are consistent with your role and experience.

<u>Equity Participation</u>. Following your commencement, Kazia will recommend to the Board of Directors that you be granted options over the company's stock, to an amount as specified in Attachment 1 of this letter.

<u>Benefits</u>. Your benefits will be as itemised in Attachment 1 of this letter.

<u>Insurance Benefits</u>.

**Severance**

If, at any time, (a) the Company terminates your employment without Cause (as defined herein), and other than as a result of your death or disability, or (b) you resign for Good Reason (as defined herein), and provided such termination constitutes a "separation from service" (as defined under Treasury Regulation Section 1.409A-1(h)), you shall be entitled to receive the following severance benefits:

&nbsp;&nbsp;&nbsp;&nbsp;(a) <u>if in Connection with a Change in Control</u>: you shall be entitled to (i) severance pay in
 the form of monthly payments equal to 12 months of your base salary in effect on the effective
 date of termination, (ii) a lump sum payout of a pro-rata bonus for the bonus year, based
 on good faith estimates of the achievement of performance goals on the date of termination,
 and (iii) if you timely elect continued health care coverage under COBRA, the Company shall
 pay the same proportion of your premium rate for you and your eligible dependents as before
 the date of termination or, if COBRA coverage is not available, then the Company shall reimburse
 you for such amount (in the same proportion as before the termination) through the earlier
 of (A) 6 months following the Separation from Service, or (B) the date upon which you and
 your eligible dependents become covered under similar plans (and you agree to notify the
 Company of such other coverage);

&nbsp;&nbsp;&nbsp;&nbsp;(b) <u>if other than in Connection with a Change in Control</u>: (i) subject to the requirement to
 mitigate below, you shall be entitled to severance pay in the form of monthly payments equal
 to a maximum of 6 months of your base salary in effect on the effective date of termination,
 (ii) a lump sum payout of a pro-rata bonus for the year, based on good faith estimates of
 the achievement of performance goals on the date of termination, and (iii) if you timely
 elect continued health care coverage under COBRA, the Company shall pay the same proportion
 of your premiums for you and your eligible dependents as before the date of termination or,
 if COBRA coverage is not available, then the Company shall reimburse you for such amount
 (in the same proportion as before the termination) through the earlier of (A) 6 months following
 the Separation from Service, or (B) the date upon which you and your eligible dependents
 become covered under similar plans (and you agree to notify the Company of such other coverage).

Such severance benefits are conditional upon (a) your continuing compliance with your obligations under your Confidentiality Agreement and Proprietary Information and Inventions Agreement; (b) your delivery to the Company of an effective general release of claims in favor of the Company and its affiliates in a form acceptable to the Company within 30 days following your termination date. The monthly severance payments and lump sum bonus payment will be subject to standard deductions and withholdings following termination; provided, however, that no payments will be made prior to the 40th day following your termination. On the 40th day following your Separation from Service date, the Company will pay you the salary continuation payments that you would have received on or prior to such date in a lump sum under the original schedule but for the delay while waiting for the effectiveness of the release, with the balance of the cash severance and the bonus payment being paid as originally scheduled.

For purposes of this letter, "Cause" means (A) your conviction (including a guilty plea or a no contest plea) of a felony, or of any other crime involving fraud, dishonesty or moral turpitude; (B) your commission of or participation in a fraud against the Company; (C) your material breach of any written agreement between you and the Company (including but not limited to your Proprietary Information Agreement) or material breach of any statutory or fiduciary duty you owe to the Company, in each case that causes material harm to the Company; or (D) your conduct that constitutes gross insubordination as reasonably determined by the Board; provided in each case that the Company gives you written notice and 30 day opportunity to cure and to be heard by the Board before its final determination.

For purposes of this letter, "Change in Control" means (A) where, as a result of any takeover bid, scheme of arrangement or any other event or transaction, a person or entity becomes entitled to more than 50% of the Shares or to all or substantially all of the Group's business and assets (provided that no sale or transfer undertaken in respect of an internal reorganisation of the structure, business or assets of the Group shall constitute a Change of Control Event); or (B) any other event determined by the Board to constitute a "Change of Control Event" for the purposes of these Rules (excluding, for the avoidance of doubt, an internal reorganisation of the structure, business or assets of the Group).

Page 2 of 8

For purposes of this letter, you shall have "Good Reason" for your resignation from your employment with the Company and/or any of its subsidiaries or parent entities or successor entities if any of the following events occur without your consent:(A) material reduction in your duties (including responsibilities and/or authorities), provided, however, that a change in job position (including a change in title) shall not be deemed a "material reduction" in and of itself unless your new duties, responsibilities and/or authorities are substantially reduced from the prior duties, responsibilities and/or authorities; (B) relocation of your principal place of employment to a place that increases your one-way commute by more than fifty (50) miles as compared to your then current principal place of employment immediately prior to such relocation; (C) a reduction of at least 10% of your gross base salary (unless pursuant to a salary reduction program applicable generally to the Company's executive employees); or (D) a change in your reporting line such that you report to a position subordinate to the Chief Executive Officer. To constitute Good Reason, you must (i) give the Company written notice of the existence of the event(s) within ninety (90) days after their occurrence; (ii) allow the Company thirty (30) days to cure the existence of the event(s); and (iii), if uncured, resign from your employment within sixty (60) days after the cure period has expired.

For purposes of this letter, "in Connection with a Change in Control" will mean if your employment is terminated during that period either three (3) months prior to or twelve (12) months following a Change in Control.

It is intended that the severance benefits payable under this letter satisfy, to the greatest extent possible, the exemptions from the application of Internal Revenue Code Section 409A provided under Treasury Regulations 1.409A 1(b)(4), 1.409A 1(b)(5) and 1.409A 1(b)(9), and this letter will be construed to the greatest extent possible as consistent with those provisions. For purposes of Code Section 409A (including, without limitation, for purposes of Treasury Regulation Section 1.409A 2(b)(2)(iii)), your right to receive instalment payments under this letter shall be treated as a right to receive a series of separate payments and, accordingly, each instalment payment hereunder shall at all times be considered a separate and distinct payment. Notwithstanding any provision to the contrary in this letter, if you are deemed by the Company at the time of your Separation from Service to be a "specified employee" for purposes of Code Section 409A(a)(2)(B)(i), to the extent delayed commencement of any portion of the severance benefits to which you are entitled under this letter is required in order to avoid a prohibited distribution under Code Section 409A(a)(2)(B)(i), such portion of your benefits shall not be provided to you prior to the earlier of (i) the expiration of the six-month period measured from the date of your Separation from Service with the Company or (ii) the date of your death. Upon the first business day following the expiration of the applicable Code Section 409A(a)(2)(B)(i) period, all payments deferred pursuant to this paragraph shall be paid in a lump sum to you, and any remaining payments due under this letter shall be paid as otherwise provided herein.

**Kazia Therapeutics Appoints James Levine as Chief Financial Officer**

**SYDNEY, Australia, June 2, 2026** – <u>Kazia Therapeutics Limited</u> (NASDAQ: KZIA) ("Kazia," "Kazia Therapeutics" or the "Company"), a clinical-stage oncology company advancing therapies designed to reprogram cancer biology and overcome treatment resistance, today announced the appointment of James Levine as Chief Financial Officer, effective June 1, 2026. Mr. Levine brings more than two decades of experience across investment banking, executive and financial leadership at publicly traded biotech companies.

"James has built an impressive career leading financial strategy, strategic transactions and major pharmaceutical collaborations, following an extensive career in investment banking," said Dr. John Friend, CEO, Kazia Therapeutics. "As we advance paxalisib and progress our pipeline, James' expertise will be central to helping us capitalize on that momentum and continue building long-term value for patients and shareholders."

Most recently, Mr. Levine served as Chief Financial Officer of Cardiff Oncology, a clinical-stage oncology company developing a PLK1 inhibitor therapy for solid tumors. Prior to Cardiff Oncology, Mr. Levine served as CFO of Cidara Therapeutics, an antifungal and antiviral biotech company, where he led the financial structuring of a $568 million licensing collaboration with Mundipharma and a $780 million global partnership with Janssen Pharmaceuticals (Johnson & Johnson). He also served as CEO of Verenium Corporation, an industrial biotech company, where he executed major asset sales for total proceeds of approximately $200 million, as well as Sapphire Energy, a human nutrition-focused biotech.

Earlier in his career, Mr. Levine spent 12 years at Goldman Sachs & Co. as a Managing Director advising pharmaceutical and biotech clients across the U.S. and Europe on financings, mergers and acquisitions and strategic transactions, including landmark deals such as the Glaxo Wellcome and SmithKline Beecham merger. Mr. Levine holds a Master of Business Administration degree from The Wharton School at the University of Pennsylvania.

"I am very excited to be joining Kazia as the Company advances paxalisib across multiple indications and builds out a promising pipeline targeting novel mechanisms of treatment resistance," added Mr. Levine. "I look forward to working closely with the management team to help translate Kazia's scientific progress into strategic and financial outcomes as we approach what we expect to be a period of meaningful clinical and strategic milestones for the Company."

**About Kazia Therapeutics**

Kazia Therapeutics Limited (NASDAQ: KZIA) is an oncology-focused drug development company, based in Sydney, Australia. The Company's lead asset, paxalisib, is an investigational brain penetrant inhibitor of the PI3K/Akt /mTOR pathway, which is being developed to treat multiple forms of cancer. Licensed from Genentech in late 2016, paxalisib is or has been the subject of 10 clinical trials. A completed Phase 2/3 study in glioblastoma (GBM-Agile) was reported in 2024, and discussions are ongoing for designing and executing a pivotal registrational study in pursuit of a standard approval. Other clinical trials involving paxalisib are ongoing in advanced breast cancer, brain metastases, diffuse midline gliomas, and primary central nervous system lymphoma, with several of these trials having reported encouraging interim data. Paxalisib was granted Orphan Drug Designation for glioblastoma by the U.S. Food and Drug Administration (FDA) in February 2018, and Fast Track Designation (FTD) for glioblastoma in August 2020. Paxalisib was also granted FTD in July 2023 for the treatment of solid tumor brain metastases harboring PI3K pathway mutations in combination with radiation therapy. Additionally, paxalisib was granted Rare Pediatric Disease Designation and Orphan Drug Designation by the FDA for diffuse intrinsic pontine glioma in August 2020 and for atypical teratoid / rhabdoid tumors in June 2022 and July 2022, respectively. Kazia is also developing EVT801, a small molecule inhibitor of VEGFR3, which was licensed from Evotec SE in April 2021. In addition to its clinical-stage programs, Kazia is advancing NDL2, a potentially first-in-class intracellular PD-L1 protein degrader program targeting a newly identified mechanism of immunotherapy resistance and metastatic progression, as well as MSETC, a potentially first-in-class SETDB1 inhibitor program intended to restore immune signaling in tumors that have become resistant to immunotherapy, including checkpoint inhibitors. Both programs are currently in preclinical development. For more information, please visit www.kaziatherapeutics.com or follow us on X @KaziaTx.
