Additional Information about the Proposed Merger and Where to Find It

This Current Report on Form 8-K does not constitute an offer to buy or sell or the solicitation of an offer to buy or sell any securities or a solicitation of any vote or approval. This Current Report on Form 8-K relates to the proposed Merger of Kintara Therapeutics, Inc. (“Kintara”) and TuHURA. In connection with the proposed Merger, Kintara will file a Registration Statement on Form S-4, which will include a document that serves as a prospectus and proxy statement of Kintara (the “proxy statement/prospectus”), and Kintara will file other documents regarding the proposed Merger with the SEC. No offering of securities shall be made, except by means of a prospectus meeting the requirements of Section 10 of the Securities Act. INVESTORS AND SECURITY HOLDERS ARE URGED TO READ THE PROXY STATEMENT/PROSPECTUS AND OTHER RELEVANT DOCUMENTS FILED WITH THE SEC CAREFULLY AND IN THEIR ENTIRETY, WHEN THEY BECOME AVAILABLE, BECAUSE THEY WILL CONTAIN IMPORTANT INFORMATION THAT STOCKHOLDERS SHOULD CONSIDER BEFORE MAKING ANY DECISION REGARDING THE PROPOSED MERGER. A definitive proxy statement/prospectus will be sent to Kintara’s stockholders. Investors and security holders will be able to obtain these documents (when available) free of charge from the SEC’s website at www.sec.gov. In addition, investors and stockholders should note that Kintara communicates with investors and the public using its website (www.kintara.com), the investor relations website (https://www.kintara.com/investors) where anyone will be able to obtain free copies of the proxy statement/prospectus and other documents filed by Kintara with the SEC, and stockholders are urged to read the proxy statement/prospectus and the other relevant materials when they become available before making any voting or investment decision with respect to the proposed Merger.

Participants in the Solicitation

Kintara, TuHURA and their respective directors and executive officers and other members of management and employees and certain of their respective significant stockholders may be deemed to be participants in the solicitation of proxies from Kintara and TuHURA stockholders in respect of the proposed Merger. Information about Kintara’s directors and executive officers is available in Kintara’s proxy statement, which was filed with the SEC on September 11, 2023 for the 2023 Annual Meeting of Stockholders, Kintara’s Annual Report on Form 10-K for the fiscal year ended June 30, 2023, which was filed with the SEC on September 18, 2023. Information regarding the persons who may, under the rules of the SEC, be deemed participants in the proxy solicitation and a description of their direct and indirect interests, by security holding or otherwise, will be contained in the proxy statement/prospectus and other relevant materials to be filed with the SEC regarding the proposed Merger when they become available. Investors should read the proxy statement/prospectus carefully when it becomes available before making any voting or investment decisions. You may obtain free copies of these documents from the SEC and Kintara as indicated above.

No Offer or Solicitation

This Current Report on Form 8-K shall not constitute an offer to sell or the solicitation of an offer to buy any securities, nor shall there be any sale of securities in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction. No offering of securities shall be made except by means of a prospectus meeting the requirements of Section 10 of the Securities Act.

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 and TuHURA’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 and TuHURA have based these forward-looking statements largely on their 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 each of Kintara’s and TuHURA’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 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.
