Exhibit 99.4

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

The following unaudited pro forma condensed combined financial information presents the combination of the financial information of Kintara and TuHURA adjusted to give effect to the Merger and related transactions. The following unaudited pro forma condensed combined financial information has been prepared in accordance with Article 11 of Regulation S-X. Defined terms included below have the same meaning as terms defined and included elsewhere in Kintara’s proxy statement/prospectus dated August 13, 2024 and filed with the SEC on August 19, 2024.

TuHURA and Kintara have different fiscal year ends. TuHURA’s year end is December 31, and Kintara’s year end is June 30. The following unaudited pro forma condensed combined financial statements have been prepared to present the combination of the historical financial statements of TuHURA and the historical financial statements of Kintara, on a pro forma basis adjusted to give effect to the Merger and related transactions. Following the Merger, the surviving company will have a fiscal year end of December 31. The unaudited pro forma condensed combined financial information includes (all financial information is prepared in accordance with GAAP):

(a) The unaudited pro forma condensed combined balance sheet as of June 30, 2024 combines (i) the unaudited condensed consolidated balance sheet of TuHURA as of June 30, 2024, as derived from its historical financial statements and (ii) the audited consolidated balance sheet of Kintara as of June 30, 2024, as filed on Kintara’s Form 10-K with the SEC on October 7, 2024, on a pro forma basis as if the Merger and related transactions had been consummated on June 30, 2024.

(b) The unaudited pro forma condensed combined statement of operations for the six months ended June 30, 2024 combines (i) the unaudited condensed consolidated statement of operations of TuHURA for the six months ended June 30, 2024, as derived from its historical financial statements and (ii) the unaudited condensed consolidated statement of operations of Kintara for the six months ended June 30, 2024, as calculated by (a) subtracting the unaudited interim condensed consolidated statement of operations of Kintara for the six months ended December 31, 2023, as filed on Kintara’s Form 10-Q with the SEC on February 14, 2024, from (b) the audited consolidated statement of operations of Kintara for the year ended June 30, 2024, as filed on Kintara’s Form 10-K with the SEC on October 7, 2024, on a pro forma basis as if the Merger and related transactions had been consummated on January 1, 2023.

(c) The unaudited pro forma condensed combined statement of operations for the year ended December 31, 2023 combines (i) the audited consolidated statement of operations of TuHURA for the year ended December 31, 2023, as derived from its historical financial statements, and (ii) the unaudited condensed consolidated statement of operations of Kintara for the year ended December 31, 2023 as calculated by (a) adding the unaudited interim condensed consolidated statement of operations of Kintara for the six months ended December 31, 2023, as filed on Kintara’s Form 10-Q with the SEC on February 14, 2024, to (b) the unaudited condensed consolidated statement of operations of Kintara for the six months ended June 30, 2023, as calculated by subtracting the unaudited interim condensed consolidated statement of operations of Kintara for the six months ended December 31, 2022, as filed on Kintara’s Form 10-Q with the SEC on February 14, 2023 from the audited consolidated statement of operations of Kintara for the year ended June 30, 2023, as filed on Kintara’s Form 10-K with the SEC on September 18, 2023, on a pro forma basis as if the Merger and related transactions had been consummated on January 1, 2023.

Such unaudited pro forma financial information has been prepared on a basis consistent with the financial statements of TuHURA, as TuHURA has been determined to be the accounting acquirer. This information should be read together with the financial statements of Kintara and TuHURA and related notes thereto, the sections titled “Kintara Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “TuHURA Management’s Discussion and Analysis of Financial Condition and Results of Operations” and other information included elsewhere in Kintara’s filings with the SEC, including the Merger Agreement and the descriptions of certain terms thereof set forth in the section titled the “Nasdaq Proposal” or “Proposal No. 1” in Kintara’s proxy

statement/prospectus dated August 13, 2024 and filed with the SEC on August 19, 2024 and this Current Report on Form 8-K.

The Merger is accounted for as a reverse recapitalization, in accordance with GAAP. Under this method of accounting, Kintara will be treated as the “acquired” company for financial reporting purposes. Accordingly, the Merger will be treated as the equivalent of TuHURA issuing stock for the net assets of Kintara, accompanied by a recapitalization. The net assets of Kintara will be stated at historical cost, with no goodwill or other intangible assets recorded. There will be no accounting effect or change in the carrying amount of the assets and liabilities as a result of the recapitalization.

TuHURA has been determined to be the accounting acquirer in the Merger for financial reporting purposes based on evaluation of the following facts and circumstances with regard to the combined company immediately after the Closing, including: (i) former TuHURA securityholders own approximately 96.0% of the Kintara Common Stock outstanding immediately following the Effective Time, (ii) TuHURA designated four of the five initial members of the board of directors of the combined company, (iii) TuHURA’s current senior management holds both (two of two) positions in the senior management of the combined company and (iv) TuHURA represents a significant majority of operations of the combined company. Total assets held by TuHURA and Kintara as of June 30, 2024 were $14,093 thousand and $6,202 thousand, respectively, as noted below, and included cash and cash equivalents held by TuHURA of $12,311 thousand and cash and cash equivalents of $4,909 thousand held by Kintara at June 30, 2024. After the Closing, the combined operations will be primarily TuHURA’s operations with the focus mainly on TuHURA’s in-process research and development assets. As a result of TuHURA being treated as the acquiring company for financial reporting purposes, the historical financial statements of TuHURA are the historical consolidated financial statements of the combined company. It is noted that the Kintara chief executive officer is not an assumed employee of the surviving company and as such is not part of the assembled workforce of the surviving company. Kintara is in the process of launching the REM-001 Study (defined below), which is a second-generation PDT photosensitizer agent, and is designed to test the 0.8 mg dose as well as optimize the study design in advance of a Phase 3 trial initiation. In addition, Kintara does not believe that the registrational study of VAL-083 is suitable for further development.

As noted in the CVR Agreement, the combined company is contractually obligated to use commercially reasonable efforts (see Note 1) until December 31, 2025 to achieve the Milestone. TuHURA anticipates the successful enrollment of the ten CMBC patients and that such patients will complete the required follow-up in accordance with the CVR Agreement. The CVR is not contingent on any future outcome of the study, clinical trials, commercialization, or economic benefit to be derived from the REM-001 Study. TuHURA’s management has concluded that it is probable that the Milestone of the Kintara legacy clinical studies pursuant to the CVR Agreement will be achieved and the CVR Shares will be issued. The REM-001 Study is currently in the early stages of the study process with no clinical trials passed or proven efficacy. Once 10 patients are enrolled and tracked in this study to determine whether a lower dose of REM-001 has an acceptable safety profile and elicits a treatment effect similar to that seen in prior REM-001 studies, the combined company expects to enroll the remaining patients and complete the NIH-funded trial and thereafter evaluate whether the REM-001 technology has potential future value that could be realized by the combined company. However, TuHURA currently anticipates no significant value derived from any in-process research and development assets of Kintara as of the Merger. Other than the REM-001 Study, TuHURA does not currently expect a restart or to advance any legacy Kintara technologies acquired. See Note 1 to the Notes to the Unaudited Pro Forma Condensed Financial Statements for the background and impact related to the potential issuance of the CVR Shares.

The unaudited pro forma condensed combined balance sheet as of June 30, 2024 combines the historical balance sheets of TuHURA and Kintara on a pro forma basis as if the Merger and related transactions had been consummated on June 30, 2024. The unaudited pro forma condensed combined statements of operations for the six months ended June 30, 2024 and for the year ended December 31, 2023 give pro forma effect to the Merger and related transactions as if they had occurred on January 1, 2023, the beginning of the earliest period presented. TuHURA and Kintara have

not had any historical operating relationship prior to the Merger. Accordingly, no pro forma adjustments were required to eliminate activities between the companies. These unaudited pro forma condensed combined financial statements are for informational purposes only. They do not purport to indicate the results that would have been obtained had the Merger and related transactions actually been completed on the assumed date or for the periods presented, or which may be realized in the future. The pro forma adjustments are based on the information currently available and the assumptions and estimates underlying the pro forma adjustments are described in the accompanying notes. Actual results may differ materially from the assumptions within the accompanying unaudited pro forma condensed combined financial information.

Description of the Merger Agreement, the TuHURA Note Financing, Exclusivity Agreement and July 2024 Private Placement

Merger Agreement

On April 2, 2024, Kintara, Merger Sub, and TuHURA entered into the Merger Agreement, pursuant to which, among other things, Merger Sub merged with and into TuHURA at the Effective Time, with TuHURA continuing as a wholly owned subsidiary of Kintara, and TuHURA Biosciences, Inc. being the surviving corporation of the Merger. At the closing of the Merger, the corporate name of Kintara was changed to “TuHURA Biosciences, Inc.”

At Effective Time, (i) each outstanding share of TuHURA Common Stock (other than any shares held in treasury and Dissenting Shares (as defined in the Merger Agreement)) was converted into shares of Kintara Common Stock equal to the Exchange Ratio (which is calculated to be 0.1789 following the effect of the 1-35 reverse share split for purposes of these unaudited pro forma condensed combined financial statements), (ii) each outstanding TuHURA Option was assumed and converted into an option to purchase shares of Kintara Common Stock and (iii) each outstanding TuHURA Warrant was assumed and converted into and exchangeable for a warrant of like tenor entitling the holder to purchase shares of Kintara Common Stock.

Immediately after the Merger, on a pro forma basis, pre-Merger TuHURA stockholders owned approximately 96.0% of the combined company, pre-Merger Kintara stockholders owned approximately 4.0% of the combined company (excluding in each such case the effect of out-of-the-money options and warrants of Kintara that remain outstanding after the Merger). The Exchange Ratio was equal to the quotient obtained by dividing (a) TuHURA Merger Shares by (b) TuHURA Outstanding Shares, as those terms are defined and further described in the Merger Agreement, which had the effect and purpose of determining the number of shares to be issued to pre-Merger TuHURA stockholders (or issuable to pre-Merger TuHURA option and warrant holders in respect of such options and warrants) based on the relative valuations and fully-diluted shares of each of Kintara and TuHURA as of immediately prior to the closing of the Merger. For purposes of calculating the Exchange Ratio, (i) shares of Kintara Common Stock underlying Kintara stock options and warrants outstanding as of immediately prior to the closing of the Merger with an exercise price per share of less than or equal to $0.20 (subject to adjustment pursuant to the Merger Agreement) were deemed to be outstanding and (ii) all shares of TuHURA Common Stock underlying outstanding TuHURA preferred stock, TuHURA Options, and TuHURA Warrants were deemed to be outstanding.

Based on the pre-Merger and post-Merger modification of the fair values of the options and warrants there are no material differences identified or noted.

TuHURA Note Financing

On December 1, 2023 (the “Initial Closing”), TuHURA’s board of directors approved the private offering of convertible promissory notes to certain accredited investors in an aggregate principal amount of up to $15 million to be used primarily to fund TuHURA’s clinical development plan and general corporate expenses (the “Convertible Debt”). The convertible promissory notes bore simple interest at a rate of 20% per annum, which was computed on the basis of a 365-day year (each a “Note,” and together, the “Notes”).

On March 29, 2024, TuHURA’s board of directors approved increasing the aggregate principal amount of the Convertible Debt to $35 million as well as that in the event a holder subscribes to purchase Notes in the aggregate principal amount of $4.0 million or more, then such holders would will be granted a TuHURA Warrant to purchase TuHURA Common Stock equal to (i) 50% of the aggregate principal amount of the Note purchased by such holder divided by (ii) $0.68. The threshold for obtaining TuHURA Warrants in connection with the TuHURA Note Financing includes principal amounts issued prior to March 29, 2024, as well as subsequent Note issuances.

The TuHURA Warrants issued in the TuHURA Note Financing may be exercised by such holder at any time within three years of the issuance date. The exercise price for one share of TuHURA Common Stock under such TuHURA Warrant is $1.02, payable in cash.

All outstanding principal and accrued but unpaid interest under the Notes was automatically converted into shares of TuHURA Common Stock immediately prior to the consummation of the Merger.

Kineta Exclusivity Agreement and July 2024 Private Placement

On July 8, 2024, Kintara and TuHURA issued a press release announcing that TuHURA has entered into an Exclusivity and Right of First Offer Agreement (the “Exclusivity Agreement”) with Kineta, Inc. (“Kineta”) for the potential acquisition of Kineta’s KVA12123 anti-VISTA antibody and related rights and assets associated with and derived from the asset.

KVA12123 is a rationally targeted, anti-VISTA antibody checkpoint inhibitor designed to reverse VISTA immune suppression and remodel the tumor microenvironment (TME) to overcome acquired resistance to immunotherapies.

Pursuant to the Exclusivity Agreement, among other things, Kineta has granted TuHURA an exclusive right to acquire Kineta’s worldwide patents, patent rights, patent applications, product and development program assets, technical and business information, and other rights and assets associated with and derived from its development program related to KVA12123 during the period commencing as of July 3, 2024 (the “Effective Date”) and continuing through the first to occur of (a) the execution of any Definitive Agreement (as defined therein) with respect to a Potential Transaction (as defined therein) by TuHURA or one or more of its affiliates and (b) 11:59 PM Eastern Time on October 1, 2024, subject to extension as noted in the following sentence (the “Exclusivity Period”). In the event that the parties are engaged in good faith discussions regarding a Potential Transaction on the date on which the Exclusivity Period (or any renewal thereof) is scheduled to expire and TuHURA has not yet closed the transactions contemplated by the Merger Agreement, then on such date, the Exclusivity Period shall automatically renew for an additional ten (10) day period (a “Renewal Period”) (up to a total of two (2) Renewal Periods for an aggregate of twenty (20) days).

Under the terms of the Exclusivity Agreement, TuHURA paid Kineta a fee in the amount of $5,000,000, with $2,500,000 paid at signing and an additional $2,500,000 paid on July 15, 2024. The fee is nonrefundable other than in the case of an uncured breach of the Exclusivity Agreement by Kineta. No later than two (2) business days after a Renewal Period has started (to be confirmed in writing by both parties), TuHURA shall pay an additional $150,000 as an additional Exclusivity Payment, in an amount not to exceed $300,000 for the two (2) available Renewal Periods. On October 4, 2024, TuHURA paid Kineta $150,000 as an additional Exclusivity Payment for the first Renewal Period. On October 15, 2024, TuHURA paid Kineta $150,000 as an additional Exclusivity Payment for the second Renewal Period. The Exclusivity Payments will be credited against the initial cash consideration that may be payable to Kineta pursuant to any Definitive Agreement (if any) between Kineta and TuHURA and/or its affiliates with respect to a Potential Transaction.

In conjunction with the Exclusivity Agreement, TuHURA sold 4,009,623 shares of its common stock in a private offering with a purchase price of $5,000,000 (the “July Private Placement”) to an existing TuHURA shareholder (the “Investor”). In connection with the July Private Placement, the Investor is entitled to a 1.5% royalty on certain sales by TuHURA of products based on KVA12123 as set forth in the Investor’s subscription agreement. Due to no definitive transaction agreement with Kineta for the purchase of KVA12123 and the inherent uncertainties surrounding the regulatory approval of KVA12123 and future monetization, TuHURA has not allocated any of the $5,000,000 purchase price consideration to the royalty agreement.

The accounting treatment for the Exclusivity Agreement and the July Private Placement is preliminary in nature and the final accounting treatment will be determined based on a number of factors, including additional analysis of the transaction and consideration of relevant accounting standards.

See accompanying notes to the unaudited pro forma condensed combined financial statements.

Note 1. Description of Transactions

Merger Transaction

On April 2, 2024, Kintara entered into the Merger Agreement with Merger Sub and TuHURA. Pursuant to the terms of the Merger Agreement, a combination of Kintara and TuHURA was effected through the merger of Merger Sub with and into TuHURA, with TuHURA continuing as a wholly owned subsidiary of Kintara.

At the Effective Time, all shares of TuHURA Common Stock outstanding immediately prior to the Effective Time (after giving effect to the conversion of TuHURA preferred stock and excluding certain excluded and dissenting shares) were converted into and became exchangeable for approximately 54.4 million shares issued in completion of the Merger in the aggregate, under the reverse share split of 1-35 effected by the Board of Directors on October 18, 2024, of the then-issued and outstanding Kintara Common Stock based on an Exchange Ratio calculated as follows:

The Exchange Ratio was calculated by dividing (a) Company Merger Shares by (b) the Company Outstanding Shares (each as defined in the Merger Agreement), which had the effect and purpose of determining the number of shares of Kintara Common Stock to be issued to pre-Merger TuHURA stockholders (or issuable to pre-Merger TuHURA Option and TuHURA Warrant holders in respect of such options and warrants) based on the relative valuations and fully-diluted shares of each of Kintara and TuHURA as of immediately prior to the closing of the Merger. For purposes of calculating the Exchange Ratio, (i) shares of Kintara Common Stock underlying Kintara stock options and warrants outstanding as of immediately prior to the closing of the Merger with an exercise price per share of less than or equal to $0.20 were deemed to be outstanding and (ii) all shares of TuHURA Common Stock underlying outstanding TuHURA preferred stock, TuHURA Options, and TuHURA Warrants were deemed to be outstanding.

Based on the relative valuations, there is no material difference between the fair value and cash value of the options and warrants and as such, they are presented at cash value on the unaudited pro forma condensed combined financial statements.

After taking into account the conversion of the Convertible Debt, immediately after the Merger, pre-Merger TuHURA stockholders owned approximately 96.0% of the combined company and pre-Merger Kintara stockholders owned approximately 4.0% of the combined company. The unaudited pro forma condensed combined financial information were prepared giving effect to the reverse share split that took place immediately prior to the closing of the Merger of the then-issued and outstanding shares of Kintara Common Stock (1-35 reverse share split):

TuHURA Note Financing

On the Initial Closing, TuHURA’s board of directors approved the private offering of the Convertible Debt to certain accredited investors in an aggregate principal amount of up to $15 million to be used primarily to fund TuHURA’s clinical development plan and general corporate expenses. The Notes bore simple interest at a rate of 20% per annum, which was computed on the basis of a 365-day year.

On March 29, 2024, TuHURA’s board of directors approved increasing the aggregate principal amount of the Convertible Debt to $35 million as well as that in the event a holder subscribes to purchase Notes in the aggregate principal amount of $4.0 million or more, then such holders would be granted a TuHURA Warrant to purchase TuHURA Common Stock equal to (i) 50% of the aggregate principal amount of the Note purchased by such holder divided by (ii) $0.68. The threshold for obtaining TuHURA Warrants in connection with the TuHURA Note Financing includes principal amounts issued prior to March 29, 2024, as well as subsequent Note issuances.

The TuHURA Warrants issued in the TuHURA Note Financing may be exercised by such holder at any time within three years of the issuance date. The exercise price for one share of TuHURA Common Stock under such TuHURA Warrant is $1.02, payable in cash.

All outstanding principal and accrued but unpaid interest under the Notes was automatically converted into shares of TuHURA Common Stock immediately prior to the consummation of the Merger.

Contingent Value Rights Agreement

Kintara entered into the CVR Agreement with the Rights Agent, on October 18, 2024, pursuant to which holders of record of Kintara Common Stock and Kintara Common Stock warrants, in each case, immediately prior to the effected reverse share split, received one CVR for each outstanding share of Kintara Common Stock held by such stockholder (or, in the case of the warrants, each share of Kintara Common Stock for which such warrant was exercisable. Each CVR entitled the holder thereof to receive its portion of 53,897,125 CVR Shares (or 1,539,918 shares after the effect of the 1-35 reverse share split) if Kintara achieves the Milestone.

The issuance of the CVR Shares is solely based on conducting a study of REM-001 with a certain number of participants and duration and is not contingent on any future outcome of the study, clinical trials, commercialization, or economic benefit to be derived from REM-001. TuHURA is not obligated to develop REM-001 besides using commercially reasonable efforts to achieve the Milestone and commercial reasonable efforts shall not require

TuHURA to expend monetary resources in excess of $700,000 after taking into account the amount Kintara reasonably believes it is eligible for and will be reimbursed (or already reimbursed) by $2 million in NIH grants under Federal Award Number 1R44CA281615-01.

TuHURA has determined that any in-process research and development assets of Kintara potentially remaining as of the Merger would not have significant value when compared to the gross assets obtained through the Merger and, other than completing the NIH-funded 15-patient REM-001 Study as described above, TuHURA does not intend to start up development efforts for any of Kintara’s legacy clinical studies following the Merger. However, TuHURA anticipates the successful enrollment of the ten CMBC patients and that such patients will complete the required follow-up. Based on these factors, TuHURA’s management has concluded that it is probable that the Milestone of the Kintara legacy clinical studies pursuant to the CVR Agreement will be achieved and the CVR shares to be issued.

Based on management’s analysis, the CVRs were identified as freestanding financial instruments and determined to be indexed to Kintara’s own stock, as they are to be settled in Kintara Common Stock. Further, the CVR financial instruments are not mandatorily redeemable as the instruments do not require Kintara to redeem them for cash or other assets at a fixed or determinable date, or upon an event that is certain to occur and the CVRs do not represent an unconditional obligation requiring Kintara to redeem the instruments. The CVRs do not represent outstanding shares of Kintara Common Stock, and the CVRs do not obligate Kintara to buy back some or all of its shares. As such, the CVRs are not precluded from being classified within equity. Given the CVRs are initially being recorded within Equity, if the CVR Milestone were to be achieved, the Company would issue additional Common Stock, thereby resulting in a reclass of the CVRs from Additional paid-in capital - CVRs to Common Stock and Additional paid-in capital. As a result, the accounting for the CVR is determined to have zero net effect on total equity within the unaudited pro forma condensed combined balance sheet as of June 30, 2024.

Equity-classified contracts are initially measured at fair value (or allocated value). Subsequent changes in fair value are not recognized if the contracts continue to be classified in equity. Kintara estimated the valuation of the CVR arrangement. Since the Milestone is based on ten participants in the REM-001 study and 8 weeks of follow-up, management determined that the achievement of the Milestone is probable at the time of the filing of this registration statement. The Merger Agreement specifies achievement of the Milestone will result in the issuance of the CVR Shares. Kintara leveraged the fair value level 1 input of the closing price of Kintara’s Common Stock on October 17, 2024, prior to the effect of the 1-35 reverse share split, of $0.2154 multiplied by 53,897,125 shares resulting in an estimated valuation of the CVR Shares of approximately $11,609,441.

Kineta Exclusivity Agreement and July 2024 Private Placement

On July 8, 2024, Kintara and TuHURA issued a press release announcing that TuHURA has entered into the Exclusivity Agreement with Kineta for the potential acquisition of Kineta’s KVA12123 anti-VISTA antibody and related rights and assets associated with and derived from the asset.

KVA12123 is a rationally targeted, anti-VISTA antibody checkpoint inhibitor designed to reverse VISTA immune suppression and remodel the tumor microenvironment (TME) to overcome acquired resistance to immunotherapies.

Pursuant to the Exclusivity Agreement, among other things, Kineta has granted TuHURA an exclusive right to acquire Kineta’s worldwide patents, patent rights, patent applications, product and development program assets, technical and business information, and other rights and assets associated with and derived from its development program related to KVA12123, during the period commencing as of the Effective Date and continuing through the first to occur of (a) the execution of any Definitive Agreement with respect to a Potential Transaction by TuHURA or one or more of its affiliates and (b) Exclusivity Period. In the event that the parties are engaged in good faith discussions regarding a Potential Transaction on the date on which the Exclusivity Period (or any renewal thereof) is scheduled to expire and TuHURA has not yet closed the transactions contemplated by the Merger Agreement then on

such date, the Exclusivity Period shall automatically renew for Renewal Period (up to a total of two (2) Renewal Periods for an aggregate of twenty (20) days).

Under the terms of the Exclusivity Agreement, TuHURA paid Kineta a fee in the amount of $5,000,000, with $2,500,000 paid at signing and, subject to certain provisions, an additional $2,500,000 paid on July 15, 2024. The fee is nonrefundable other than in the case of an uncured breach of the Exclusivity Agreement by Kineta. No later than two (2) business days after a Renewal Period has started (to be confirmed in writing by both parties), TuHURA shall pay an additional $150,000 as an additional Exclusivity Payment, in an amount not to exceed $300,000 for the two (2) available Renewal Periods. On October 4, 2024, TuHURA paid Kineta $150,000 as an additional Exclusivity Payment for the first Renewal Period. On October 15, 2024, TuHURA paid Kineta $150,000 as an additional Exclusivity Payment for the second Renewal Period. The Exclusivity Payments will be credited against the initial cash consideration that may be payable to Kineta pursuant to any Definitive Agreement (if any) between Kineta and TuHURA and/or its affiliates with respect to a Potential Transaction.

In conjunction with the Exclusivity Agreement, TuHURA sold 4,009,623 of shares of its common stock with a purchase price of $5,000,000 in the July Private Placement to the Investor. In connection with the July Private Placement, the Investor is entitled to a 1.5% royalty on certain sales by TuHURA of products based on KVA12123 as set forth in the Investor’s subscription agreement. Due to no definitive transaction agreement with Kineta for the purchase of KVA12123 and the inherent uncertainties surrounding the regulatory approval of KVA12123 and future monetization, TuHURA has not allocated any of the $5,000,000 purchase price consideration to the royalty agreement.

On August 19, 2024, TuHURA and Kintara announced in a new press release that Kineta has reopened enrollment in its ongoing VISTA-101 Phase 1/2 clinical trial. Kineta and TuHURA are cooperating on the reinitiation of patient enrollment into this trial during TuHURA’s due diligence period with respect to the KVA12123 assets. 30 of a projected 39 patients have been enrolled in the clinical trial to date, including a monotherapy arm with KVA12123 and a combination arm utilizing KVA12123 together with Merck’s anti-PD1 therapy, KEYTRUDA® (pembrolizumab).

To date, KVA12123 has cleared the fifth of six monotherapy dose levels and two of the four cohorts in combination with Merck's anti-PD1 therapy, KEYTRUDA® (pembrolizumab). Initial results demonstrating partial response and stable disease in the combination cohorts, and durable stable disease observed in monotherapy cohorts, were reported earlier this year at the American Association of Cancer Research (AACR) Annual Meeting 2024. Additionally, the initial results of KVA12123 showed a favorable clinical safety and tolerability profile with no dose limiting toxicities and no evidence of cytokine release syndrome (CRS)-associated cytokines at any dose level.

The accounting treatment for the Exclusivity Agreement and the July Private Placement is preliminary in nature and the final accounting treatment will be determined based on a number of factors, including additional analysis of the transaction and consideration of relevant accounting standards.

Note 2. Basis of Presentation

The Merger was accounted as a reverse recapitalization, where the assets and liabilities of Kintara are recorded at their carrying values, with no goodwill or other intangible assets recorded, in accordance with GAAP. Under this method of accounting, Kintara was treated as the “accounting acquiree” and TuHURA as the “accounting acquirer” for financial reporting purposes. The determination of TuHURA as the accounting acquirer was primarily based on the evaluation of the following facts and circumstances:

Accordingly, for accounting purposes, the Merger was treated as the equivalent of TuHURA issuing shares for the net assets of Kintara, followed by a recapitalization. The net assets of TuHURA are stated at historical cost. Operations prior to the Merger will be those of TuHURA.

The unaudited pro forma condensed combined balance sheet as of June 30, 2024 gives effect to the Merger and related transactions as if they occurred on June 30, 2024. The unaudited pro forma condensed combined statements of operations for the six months ended June 30, 2024 and for the year ended December 31, 2023 give effect to the Merger and related transactions as if they occurred on January 1, 2023. These periods are presented on the basis that TuHURA is the acquirer for accounting purposes.

The pro forma adjustments reflecting the consummation of the Merger and the related transaction are based on certain currently available information and certain assumptions and methodologies that TuHURA management believes are reasonable under the circumstances. The unaudited condensed combined pro forma adjustments, which are described in the accompanying notes, may be revised as additional information becomes available and is evaluated. Therefore, it is likely that the actual adjustments will differ from the pro forma adjustments, and it is possible that the difference may be material. TuHURA management believes that its assumptions and methodologies provide a reasonable basis for presenting all of the significant effects of the Merger and the related transactions based on information available to management at this time and that the pro forma adjustments give appropriate effect to those assumptions and are properly applied in the unaudited pro forma condensed combined financial information.

The unaudited pro forma condensed combined financial information does not give effect to any anticipated synergies, operating efficiencies, tax savings, or cost savings that may be associated with the Merger. The unaudited pro forma condensed combined financial information is not necessarily indicative of what the actual results of operations and financial position would have been had the Merger and related transactions taken place on the dates indicated, nor are they indicative of the future consolidated results of operations or financial position of the post-combination company. They should be read in conjunction with the separate historical unaudited financial statements and notes thereto of Kintara and TuHURA included elsewhere in the filings of Kintara with the SEC.

Immediately prior to the Effective Time, TuHURA preferred stock was converted into TuHURA Common Stock that was subsequently converted into and was exchanged for shares of Kintara Common Stock issued upon completion of the Merger at the Effective Time and in accordance with the Merger Agreement and the Exchange Ratio.

To the extent there are significant changes to the business following completion of the Merger, the assumptions and estimates set forth in the unaudited pro forma condensed combined financial statements could change significantly. Accordingly, the pro forma adjustments are subject to further adjustments as additional information

becomes available and as additional analyses are conducted following the completion of the Merger. There can be no assurances that these additional analyses will not result in material changes to the estimates.

The unaudited pro forma condensed combined financial information does not reflect the income tax effects of the pro forma adjustments as any change in the deferred tax balance would be offset by an increase in the valuation allowance given that TuHURA incurred significant losses during the historical periods presented.

The pro forma basic and diluted loss per share amounts presented in the unaudited pro forma condensed combined statements of operations are based upon the number of the combined company’s common shares outstanding following the reverse share split of 1-35 as effected on October 18, 2024, and assuming the Merger occurred on January 1, 2023.

Note 3. Accounting Polices

Management will perform a comprehensive review of the two entities’ accounting policies. As a result of the review, management may identify differences between the accounting policies of the two entities which, when conformed, could have a material impact on the financial statements of the post-combination company. Based on its initial analysis, management did not identify any differences that would have a material impact on the unaudited pro forma condensed combined financial information. As a result, the unaudited pro forma condensed combined financial information does not assume any differences in accounting policies.

TuHURA Note Financing

On the Initial Closing, TuHURA’s board of directors approved the private offering of the Convertible Debt to certain accredited investors in an aggregate principal amount of up to $15 million to be used primarily to fund TuHURA’s clinical development plan and general corporate expenses. The Notes bore simple interest at a rate of 20% per annum, which was computed on the basis of a 365-day year.

On March 29, 2024, TuHURA’s board of directors approved increasing the aggregate principal amount of the Convertible Debt to $35 million as well as that in the event a holder subscribes to purchase Notes in the aggregate principal amount of $4.0 million or more, then such holders would be granted a TuHURA Warrant to purchase TuHURA Common Stock equal to (i) 50% of the aggregate principal amount of the Note purchased by such holder divided by (ii) $0.68. The threshold for obtaining TuHURA Warrants in connection with the TuHURA Note Financing includes principal amounts issued prior to March 29, 2024, as well as subsequent Note issuances.

The TuHURA Warrants issued in the TuHURA Note Financing may be exercised by such holder at any time within three years of the issuance date. The exercise price for one share of TuHURA Common Stock under such TuHURA Warrant is $1.02, payable in cash.

All outstanding principal and accrued but unpaid interest under the Notes was automatically converted into shares of TuHURA Common Stock immediately prior to the consummation of the Merger.

Kineta Exclusivity Agreement and July 2024 Private Placement

On July 8, 2024, Kintara and TuHURA issued a press release announcing that TuHURA has entered into the Exclusivity Agreement with Kineta for the potential acquisition of Kineta’s KVA12123 anti-VISTA antibody and related rights and assets associated with and derived from the asset.

Pursuant to the Exclusivity Agreement, among other things, Kineta has granted TuHURA an exclusive right to acquire Kineta’s worldwide patents, patent rights, patent applications, product and development program assets,

technical and business information, and other rights and assets associated with and derived from its development program related to KVA12123, Kinteta’s VISTA blocking immunotherapy, during the period commencing as of the Effective Date and continuing through the first to occur of (a) the execution of any Definitive Agreement with respect to a Potential Transaction by TuHURA or one or more of its affiliates and (b) Exclusivity Period. In the event that the parties are engaged in good faith discussions regarding a Potential Transaction on the date on which the Exclusivity Period (or any renewal thereof) is scheduled to expire and TuHURA has not yet closed the transactions contemplated by the Merger Agreement then on such date, the Exclusivity Period shall automatically renew for Renewal Period (up to a total of two (2) Renewal Periods for an aggregate of twenty (20) days).

Under the terms of the Exclusivity Agreement, TuHURA paid Kineta a nonrefundable amount of $5,000,000, with $2,500,000 paid at signing and, subject to certain provisions, an additional $2,500,000 paid on July 15, 2024. No later than two (2) business days after a Renewal Period has started (to be confirmed in writing by both parties), TuHURA shall pay an additional $150,000 as an additional Exclusivity Payment, in an amount not to exceed $300,000 for the two (2) available Renewal Periods. On October 4, 2024, TuHURA paid Kineta $150,000 as an additional Exclusivity Payment for the first Renewal Period. On October 15, 2024, TuHURA paid Kineta $150,000 as an additional Exclusivity Payment for the second Renewal Period. The Exclusivity Payments will be credited against the initial cash consideration that may be payable to Kineta pursuant to any Definitive Agreement (if any) between Kineta and TuHURA and/or its affiliates with respect to a Potential Transaction.

In conjunction with the Exclusivity Agreement, TuHURA sold 4,009,623 shares of its common stock with a purchase price of $5,000,000 in the July Private Placement to the Investor. In connection with the July Private Placement, the Investor is entitled to a 1.5% royalty on certain sales by TuHURA of products based on KVA12123 as set forth in the Investor’s subscription agreement. Due to no definitive transaction agreement with Kineta for the purchase of KVA12123 and the inherent uncertainties surrounding the regulatory approval of KVA12123 and future monetization, TuHURA has not allocated any of the $5,000,000 purchase price consideration to the royalty agreement.

On August 19, 2024, TuHURA and Kintara announced in a new press release that Kineta has reopened enrollment in its ongoing VISTA-101 Phase 1/2 clinical trial. Kineta and TuHURA are cooperating on the reinitiation of patient enrollment into this trial during TuHURA’s due diligence period with respect to the KVA12123 assets. 30 of a projected 39 patients have been enrolled in the clinical trial to date, including a monotherapy arm with KVA12123 and a combination arm utilizing KVA12123 together with Merck’s anti-PD1 therapy, KEYTRUDA® (pembrolizumab).

To date, KVA12123 has cleared the fifth of six monotherapy dose levels and two of the four cohorts in combination with Merck's anti-PD1 therapy, KEYTRUDA® (pembrolizumab). Initial results demonstrating partial response and stable disease in the combination cohorts, and durable stable disease observed in monotherapy cohorts, were reported earlier this year at the American Association of Cancer Research (AACR) Annual Meeting 2024. Additionally, the initial results of KVA12123 showed a favorable clinical safety and tolerability profile with no dose limiting toxicities and no evidence of cytokine release syndrome (CRS)-associated cytokines at any dose level.

The accounting treatment for the Exclusivity Agreement and the July 2024 Private Placement is preliminary in nature and the final accounting treatment will be determined based on a number of factors, including additional analysis of the transaction and consideration of relevant accounting standards.
