TuHURA Biosciences SEC Filings

TuHURA Biosciences, Inc. insider James Bianco, the company’s chief executive officer and a director, reported acquiring stock options on 12/12/2025. The options give him the right to buy up to 3,414,891 shares of TuHURA common stock at an exercise price of $1.02 per share and are scheduled to expire on 12/12/2035.

According to the filing, these options were acquired in a single transaction coded "A" and had a reported price of $0 for the derivative security itself. A footnote explains that one-third of the options become exercisable on each of the first, second, and third anniversaries of December 12, 2025. Following this transaction, Bianco beneficially owns 3,414,891 stock options directly.

TuHURA Biosciences, Inc. reports that a previously registered offer and sale of up to 9,321,545 shares of its common stock will now be covered by its effective Form S-3 shelf registration statement. These shares consist of 4,570,629 shares of common stock sold in a June 2, 2025 private placement and 4,750,916 shares issuable upon exercise of related warrants, all originally registered on a Form S-1 resale registration statement.

The Form S-3 shelf registration statement (File No. 333-291239), initially filed on November 3, 2025, became effective on November 22, 2025 under Section 8(a) of the Securities Act. Under Section 415(a)(6), the earlier Form S-1 resale registration is deemed terminated, and the same selling securityholders may now offer the same shares from time to time under the new shelf registration.

TuHURA Biosciences, Inc. has filed a mixed shelf prospectus allowing it to offer and sell up to $250,000,000 of debt, common stock, preferred stock, warrants, subscription rights, units and purchase contracts over time. The prospectus also registers 9,321,545 shares of common stock for resale by existing investors, including 4,570,629 outstanding shares and 4,750,916 shares issuable upon warrant exercise; TuHURA will not receive proceeds from these stockholder resales. The company is a clinical-stage immuno-oncology business, led by its IFx platform and a Phase 3 trial of IFx-2.0 in Merkel cell carcinoma, and plans to investigate TBS-2025 in a Phase 2 trial in AML. TuHURA states that net proceeds from its own future offerings will be used for working capital, Kineta merger-related costs and to advance its IFx-2.0 and TBS-2025 programs.

TuHURA Biosciences, Inc. reported that it has prepared updated unaudited pro forma financial information reflecting its recent merger activity.

In addition, TuHURA previously closed a reverse merger with Kintara Therapeutics, Inc. on October 18, 2024.

TuHURA is now providing an unaudited pro forma condensed combined statement of operations for the nine months ended September 30, 2025 and for the year ended December 31, 2024, as if both the Kineta transaction and the Kintara reverse merger had occurred on January 1, 2024.
