Kintara Therapeutics Announces Correction to Prior Announcement Regarding 1-for-35 Reverse Stock Split in Connection with the Proposed Merger with TuHURA Biosciences to Close on October 18, 2024

SAN DIEGO, Oct. 16, 2024 /PRNewswire/ -- Kintara Therapeutics, Inc. ("Kintara") (NASDAQ:KTRA), a biopharmaceutical company focused on the development of new solid tumor cancer therapies, today announced a correction to the press release previously issued by Kintara on October 16, 2024. Kintara announced today that its Board of Directors (the "Board") has approved a reverse stock split of Kintara's common stock at a ratio of 1-for-35. Kintara's common stock is expected to begin trading on a post-reverse stock split basis on the Nasdaq Capital Market on October 18, 2024, under the new name TuHURA Biosciences, Inc. and under the new symbol "HURA" following the anticipated closing of the merger (the "Merger") with TuHURA Biosciences, Inc. ("TuHURA"), with a new CUSIP number 898920 103. This press release corrects the previous announcement which contained a scrivener's error stating Kintara's common stock was expected to begin trading on a post-reverse stock split basis on October 17, 2024; as correctly stated above, Kintara's common stock is expected to begin trading on a post-reverse stock split basis on October 18, 2024.

The reverse stock split was approved by Kintara's stockholders at Kintara's special meeting of stockholders held on October 4, 2024, to be effected in the Board's discretion of not less than 1-for-20 and not more than 1-for-40. The final reverse stock split ratio of 1-for-35 was approved by the Board on October 4, 2024.

As a result of the reverse stock split, every thirty-five pre-split shares of Kintara's common stock outstanding will become one share of common stock. The reverse stock split is expected to reduce the number of shares of Kintara's outstanding common stock from approximately 55.6 million shares to approximately 1.6 million shares. The par value of Kintara's common stock will remain unchanged at $0.001 per share after the reverse stock split. The reverse stock split will not change the authorized number of shares of Kintara's common stock. The reverse stock split will affect all stockholders uniformly and will not alter any stockholder's percentage interest in Kintara's equity, except to the extent that the reverse stock split results in some stockholders owning a fractional share. No fractional shares will be issued in connection with the reverse stock split. Instead, in lieu of any fractional shares to which a stockholder of record would otherwise be entitled as a result of the reverse stock split, Kintara will issue to such stockholder such additional fraction of a share as is necessary to increase such resulting fractional share to a full share of common stock. The reverse stock split will also apply to common stock issuable upon the exercise of Kintara's outstanding warrants and stock options, with a proportionate adjustment to the exercise prices thereof, and under Kintara's equity incentive plans.

Following the closing of the Merger, the combined company's total outstanding common stock is expected to be approximately 42.0 million shares.

Equinity Trust Company, LLC is acting as the exchange agent and transfer agent for the reverse stock split. Stockholders holding their shares in book-entry form or in brokerage accounts need not take any action in connection with the reverse stock split. Beneficial holders are encouraged to contact their bank, broker or custodian with any procedural questions.
