Item 7.01. Regulation FD Disclosure.

On July 1, 2024, Kintara Therapeutics, Inc. (“Kintara”)and TuHURA Biosciences, Inc. (“TuHURA”) issued a press release providing an overview of Kintara’s and TuHURA’s recent corporate and clinical advancements and outlining upcoming expected near term milestones.

The information in this Current Report on Form 8-K under Item 7.01, including the information contained in Exhibit 99.1, is being furnished to the Securities and Exchange Commission (the “SEC”), and shall not be deemed to be “filed” for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, and shall not be deemed to be incorporated by reference into any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by a specific reference in such filing.

Item 8.01 Other Events.

On July 1, 2024, Kintara and TuHURA provided an overview of Kintara’s and TuHURA’s recent corporate and clinical advancements and outlined upcoming expected near term milestones.

As previously disclosed, in April 2024, Kintara entered into a definitive merger agreement (the “Merger Agreement”) with TuHURA, pursuant to which Kayak Mergeco, Inc., Kintara's wholly-owned subsidiary will merge with and into TuHURA with TuHURA surviving the merger and becoming Kintara's direct, wholly-owned subsidiary (the "Merger"). The Merger is expected to close in the third quarter of 2024. Kintara’s existing stockholders will own approximately 5.5% of combined company’s common stock at the closing of the Merger, inclusive of the contingent value right (“CVR”) linked to the achievement of enrollment of a minimum of 10 patients in the REM-001 study, with such patients each completing 8 weeks of follow-up on or before December 31, 2025.

TuHURA is expected to advance a single Phase 3 trial for IFx-2.0 personalized cancer vaccine as adjunctive therapy with Keytruda® in first-line treatment for advanced Merkel cell carcinoma in the second half of 2024 under FDA's accelerated approval pathway. TuHURA’s first-in-class bifunctional Antibody Drug Conjugates (“ADCs”) represent potential upside partnering opportunities. TuHURA has secured $31 million subscribed financing in connection with the Merger Agreement which is expected to provide cash runway into late 2025.

As previously disclosed, on June 12, 2024, Kintara received a 180-day extension until December 9, 2024 from The Nasdaq Stock Market LLC (“Nasdaq”) to regain compliance with the minimum bid price requirement for continued listing on The Nasdaq Capital Market, in accordance with Nasdaq Listing Rule 5810(c)(3)(A).

Kintara has also advanced enrollment, dosing and clinical site expansion in Kintara’s open label 15-patient REM-001 study in cutaneous metastatic breast cancer (“CMBC”). As of June 26, 2024, four patients have been dosed in the open label 15-patient REM-001 study CMBC. In addition to Memorial Sloan Kettering Cancer Center, Montefiore Medical Center and the University Hospital for Albert Einstein College of Medicine will soon begin screening patients. The majority of the costs to run this study will be covered by the $2.0 million Small Business Innovation Research (“SBIR”) grant Kintara was awarded from the National Institutes of Health (“NIH”). In March 2024, Kintara expanded inclusion criteria in the open label 15-patient REM-001 study in CMBC to include patients receiving pembrolizumab (KEYTRUDA®) for at least three months at screening. This is expected to significantly increase the pace of enrollment.

Kintara and TuHURA expect to close the Merger by the third calendar quarter of 2024. Kintara expects to complete enrollment and an 8-week follow-up of 10 patients in the REM-001 study by the fourth calendar quarter of 2024. TuHURA expects to commence its Phase 3 trial for IFx-2.0 personalized cancer vaccine for advanced Merkel cell carcinoma under FDA's accelerated approval pathway by the second half of calendar year 2024.

Forward-Looking Statements

This Current Report on Form 8-K and the press release attached hereto as Exhibit 99.1 contain forward-looking statements based upon Kintara’s current expectations. This communication contains “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements are identified by terminology such as “believe,” “may,” “will,” “estimate,” “continue,” “anticipate,” “intend,” “could,” “should,” “would,” “project,” “plan,” “expect,” “goal,” “seek,” “future,” “likely” or the negative or plural of these words or similar expressions. These statements are only predictions. Kintara has based these forward-looking statements largely on its then-current expectations and projections about future events, as well as the beliefs and assumptions of management. Forward-looking statements are subject to a number of risks and uncertainties, many of which involve factors or circumstances that are beyond Kintara’s control, and actual results could differ materially from those stated or implied in forward-looking statements due to a number of factors, including but not limited to: (i) the risk that the conditions to the closing or consummation of the proposed Merger are not satisfied, including the failure to obtain stockholder approval for the proposed Merger; (ii) uncertainties as to the timing of the consummation of the proposed Merger and the ability of each of Kintara and TuHURA to consummate the transactions contemplated by the proposed

Merger; (iii) risks related to Kintara’s and TuHURA’s ability to correctly estimate their respective operating expenses and expenses associated with the proposed Merger, as applicable, as well as uncertainties regarding the impact any delay in the closing would have on the anticipated cash resources of the resulting combined company upon closing and other events and unanticipated spending and costs that could reduce the combined company’s cash resources; (iv) the occurrence of any event, change or other circumstance or condition that could give rise to the termination of the proposed Merger by either Kintara or TuHURA; (v) the effect of the announcement or pendency of the proposed Merger on Kintara’s or TuHURA’s business relationships, operating results and business generally; (vi) costs related to the proposed Merger; (vii) the outcome of any legal proceedings that may be instituted against Kintara, TuHURA, or any of their respective directors or officers related to the Merger Agreement or the transactions contemplated thereby; (vii) the ability of Kintara or TuHURA to protect their respective intellectual property rights; (viii) competitive responses to the proposed Merger; (ix) unexpected costs, charges or expenses resulting from the proposed Merger; (x) whether the combined business of TuHURA and Kintara will be successful; (xi) legislative, regulatory, political and economic developments; and (xii) additional risks described in the “Risk Factors” section of Kintara’s Annual Report on Form 10-K for the fiscal year ended June 30, 2023, and the registration statement on Form S-4 related to the proposed Merger filed with the SEC. Additional assumptions, risks and uncertainties are described in detail in Kintara’s registration statements, reports and other filings with the SEC, which are available on Kintara’s website, and at www.sec.gov. Accordingly, you should not rely upon forward-looking statements as predictions of future events. Neither Kintara nor TuHURA can assure you that the events and circumstances reflected in the forward-looking statements will be achieved or occur, and actual results could differ materially from those projected in the forward-looking statements. The forward-looking statements made in this communication relate only to events as of the date on which the statements are made. Except as required by applicable law or regulation, Kintara and TuHURA undertake no obligation to update any forward-looking statement to reflect events or circumstances after the date on which the statement is made or to reflect the occurrence of unanticipated events. Investors should not assume that any lack of update to a previously issued “forward-looking statement” constitutes a reaffirmation of that statement.
