Note 1 Description of business

TuHURA Biosciences, Inc. (the Company ) is a clinical stage immuno-oncology company, headquartered in Tampa, Florida. The Company's principal products, collectively referred to as ImmuneFx ( IFx ), are a platform of cancer vaccines that utilize both cell and gene therapies to stimulate the immune system to recognize and combat tumor cells. More specifically, IFx employs the expression of a proprietary protein, Emm55, which evokes enhanced tumor recognition and broad immune activation. This leads to a systemic and sustained response against tumor cells of the type that expressed the protein. Importantly, this mechanism of action has applicability to a wide range of cancer sub-types, and the clinical development program is, therefore, multi-pronged. In 2020, the Company completed a first human clinical trial, a Phase I trial for melanoma, at Moffitt Cancer Center in Tampa, Florida. The Company completed another Phase I trial for Merkel and Squamous cell cancer and is preparing a Phase II trial for Merkel cell carcinoma that is expected to begin in the second half of 2024.

In addition to its cancer vaccine product candidates, the Company is leveraging its Delta receptor technology to develop first-in-class bi-functional antibody drug conjugates ( ADC's ), targeting Myeloid Derived Suppressor Cells ( MDSCs ) to inhibit their immune suppressing effects on the tumor microenvironment to prevent T cell exhaustion and acquired resistance to checkpoint inhibitors and cellular therapies.

Merger with Kintara As of April 2, 2024, the Company entered into a definitive agreement with Kintara, a publicly traded company on NASDAQ, for an all-stock transaction forming a company with expertise and resources to advance a risk diversified late-stage oncology pipeline. Upon completion of the merger, the former Company shareholders will own the majority of the shares of the public company. The new combined company shares are expected to trade on NASDAQ under the symbol HURA . The transaction is expected to close in the fourth quarter of 2024 and accounted for as a reverse recapitalization in accordance with GAAP, with Kintara treated as the acquired company for financial reporting purposes, and the Company treated as the accounting acquirer.

Note 2 Summary of significant accounting policies

Basis for Consolidation The consolidated financial statements are comprised of all of the accounts of TuHURA Biosciences, Inc. and Veterinary Oncology Services, a wholly owned subsidiary (collectively the Company ). All intercompany accounts and transactions have been eliminated in consolidation.

Accounting Estimates The preparation of consolidated financial statements in conformity with generally accepted accounting principles in the United States of America ( U.S. GAAP ) requires management to make estimates and assumptions that affect various amounts reported in consolidated financial statements and accompanying notes. Actual results could differ from those estimates.

Deferred Offering Costs Deferred offering costs consist of direct legal, accounting, and other fees and costs directly related to the Company's pending merger (See note 1). The Company capitalized deferred offering costs prior to the close of the merger.

Property and Equipment Property and equipment are carried at cost, less accumulated depreciation and amortization. Depreciation is computed using the straight-line method over the estimated useful lives of the assets (generally five to seven years). Leasehold improvements are amortized straight-line over the shorter of the lease term or the estimated useful life of the asset. Property and equipment are reviewed for impairment when events or changes in circumstances indicate that the carrying amount may not be recoverable. No impairment was recorded for the period ended June 30, 2024, nor the year ended December 31, 2023.

Lease Accounting The Company recognizes right-of-use lease assets and corresponding liabilities arising from leasing activities over the requisite lease period.

Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740), which enhances the income tax disclosure requirements for public entities on an annual basis. Under ASU 2023-09, public entities will be required to disclose in their rate reconciliation, on an annual basis, both percentages and amounts in their reporting currency for certain categories in a tabular format, with accompanying qualitative disclosures. The amendments in ASU 2023-09 are effective fiscal years beginning after December 31, 2024, and early adoption is permitted. The Company does not believe that the adoption of ASU 2023-09 will have a material impact on its condensed consolidated financial statements.

Research and Development Expenses Research and development consists of expenses incurred in connection with the discovery and development of product candidates. The Company expenses research and development costs as incurred.

Acquired In-Process Research and Development - Acquired in-process research and development expenses consist of existing research and development projects at the time of the acquisition. Projects that qualify as IPR&D assets represent those that have not yet reached technological feasibility and had no alternative future use, which resulted in a write-off of these IPR&D assets to acquired in-process research and development expenses in our consolidated statements of operations.

Concentration of Credit Risk The Company maintains cash balances in domestic financial institutions. These balances are insured by the Federal Deposit Insurance Corporation up to $250,000. As of June 30, 2024, the uninsured portion of cash held by the Company was approximately $11,746,000.

Note 2 Summary of significant accounting policies (continued)

Fair Value of Financial Instruments - ASC 820, Fair Value Measurement, establishes a fair value hierarchy for instruments measured at fair value that distinguishes between assumptions based on market data (observable inputs) and the Company's own assumptions (unobservable inputs). Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company's assumptions about the inputs that market participants would use in pricing the asset or liability, and are developed based on the best information available in the circumstances.

ASC 820 identifies fair value as the exchange price, or exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As a basis for considering market participant assumptions in fair value measurements, ASC 820 establishes a three-tier fair value hierarchy that distinguishes between the following:

To the extent that the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized in Level 3. A financial instrument's level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. See Note 7 for more information related to the Company's Level 3 fair value measurement.

The carrying values reported in the Company's balance sheets for cash and cash equivalents, other current assets, accounts payable, and accrued expenses are reasonable estimates of their fair values due to the short-term nature of these items.

Derivative Financial Instruments The Company evaluates all of its agreements to determine if such instruments have derivatives or contain features that qualify as embedded derivatives. The Company accounts for certain make-whole features that are associated with convertible notes as derivative liabilities at fair value and adjusts the instruments to their fair value at the end of each reporting period. Derivative financial liabilities are initially recorded at fair value, with gains and losses arising from changes in the fair value recognized in other income (expense) in the accompanying consolidated statements of operations for each reporting period while such instruments are outstanding. The embedded derivative liabilities are valued using a probability-weighted expected return method ( PWERM ). The critical inputs used to value the PWERM are a discount rate of 19.68%, the estimated make-whole interest payments for various settlement scenarios and the probability of each settlement scenario. If the Company repays the noteholders or if, during the next round of financing, the noteholders convert the debt into equity, the derivative financial liabilities will be de-recognized and reclassified to the condensed consolidated statements of stockholders' (deficit) equity on that date. Derivative instrument liabilities are classified in the balance sheet as current or non-current based on whether or not net-cash settlement of the derivative instrument could be required within 12 months of the balance sheet date.

Note 2 Summary of significant accounting policies (continued)

Debt Discount and Debt Issuance Costs- Debt issuance costs are deferred and presented as a reduction to the convertible note payable. The initial fair value of the derivative liability on the make-whole premium is treated as a debt discount. Debt discount and debt issuance costs are amortized using the effective interest rate method over the term of the convertible promissory note. Amortization of debt discount and debt issuance costs are included within interest expense in the condensed consolidated statements of operations.

Stock Compensation Expense The Company accounts for stock-based awards to employees and nonemployees using the fair value-based method to determine compensation for all arrangements where shares of stock or equity instruments are issued for compensation. Fair value of each common stock option is estimated on the date of grant using the Black-Scholes valuation model. The Black-Scholes model uses assumptions for expected volatility, expected dividends, expected term, and the risk-free interest rate. Expected volatility is based on historical volatility of a peer group's common stock and other factors estimated over the expected term of the options. The expected term of the options granted is derived using the simplified method which computes expected term as the average of the sum of the average vesting term plus the contract term.

The risk-free rate is based on the U.S. Treasury yield.

Common Stock Valuation We are required to estimate the fair value of the common stock underlying our equity awards when performing fair value calculations. The fair value of the common stock underlying our equity awards was determined on each grant taking into account input from management and taking into account the pricing offered in our equity raises. All options to purchase shares of our common stock are intended to be granted with an exercise price per share no less than the fair value per share of our common stock underlying those options on the date of grant, based on the information known to us on the date of grant. In the absence of a public trading market for our common stock, on each grant date we develop an estimate of the fair value of our common stock in order to determine an exercise price for the option grants. Our determinations of the fair value of our common stock were made by considering the prices of preferred stock sold to investors in arm's length transactions and the rights, preferences and privileges of our preferred stock relative to those of our common stock.

Business Combinations and Asset Acquisitions We account for acquired businesses using the acquisition method of accounting, which requires that the assets acquired, and liabilities assumed be recorded at the date of acquisition at their respective fair values if the acquisition meets the definition of a business combination. If the acquisition does not meet the definition of a business combination, then it is accounted for as an asset acquisition and the purchase consideration is allocated to the acquired assets.

ASC 805, Business Combinations, provides a model for determining whether an acquisition represents a business combination. In order to be a business, the integrated set of activities of the acquired entity needs to have an input and a substantive process that together significantly contribute to the ability to create outputs. The acquired entity must also pass the Screen Test which involves determining whether the acquisition represents an in-substance asset acquisition based on whether the fair value of the gross assets acquired is substantially all concentrated in a single asset or group of similar assets. This evaluation excludes certain acquired assets such as cash, deferred taxes, and goodwill associated with deferred taxes, but includes all other gross assets, including any consideration transferred in excess of the identified assets.

Note 3 Liquidity and management's plans

The Company has been engaged in research and development activities related to ImmuneFx, the Company's patented product, which will require additional investment until revenue-generating activities can begin.

The Company has historically incurred negative cash flows from operations. For the six months ended June 30, 2024, the Company incurred $8.9 million of negative cash flows from operations. The Company has approximately $12.3 million of cash and cash equivalents on hand at June 30, 2024. The Company expects that this, along with the $9,500,000 convertible note subscription agreement received in the third quarter of 2024, will be able to fund future operations, including the expanded clinical trials into the second half of 2025.

The Company expects to raise cash through the sale of common shares, issuance of convertible notes, obtaining grants, or commercial partnerships. However, there can be no assurance that any fundraising will be achieved or on commercially reasonable terms, if at all. As such, there is substantial doubt about the Company's ability to continue as a going concern for the next 12 months from date that the financial statements were available to be issued.

Note 7 Convertible promissory notes

On various dates beginning on December 11, 2023 through June 27, 2024, the Company entered into Convertible Promissory Note Agreements (the Notes ) with various entities at various amounts for an aggregate of $21,753,000. The Notes bear interest at a rate of twenty percent (20%) per annum and mature on the second anniversary of the issuance date. In addition, the Company included an additional clause for investors which grants common stock purchase warrants (the Warrants ) to Holders in the event they subscribe to purchase Notes in the aggregate principal amount of more than $4.0 million or more equal to (i) 50% of the aggregate principal amount of the Note purchased divided by $0.68 (see note 8). The Warrants related to these Convertible Promissory Notes have an exercise price of $1.02 per share and expire three years from the date of issuance.

The Notes are convertible into New Securities (depending on the applicable conversion event) upon the following: (i) automatic conversion upon an initial public offering ( Mandatory Conversion 1 ), (ii) automatic conversion upon the occurrence of a de-SPAC transaction ( Mandatory Conversion 2 ), (iii) automatic conversion upon the occurrence of a reverse public merger transaction ( Specified Merger Transaction ) at a conversion price equal to (a) the outstanding principal and interest of the Notes prior to conversion divided by (b) $0.68 ( Mandatory Conversion 3 ), or (iv) optional new securities conversion upon a qualified equity financing, transaction, series of transactions, or merger other than an IPO or de-SPAC transaction, as defined per the terms of the Note Agreement.

The Holder has the option, at the occurrence of qualified equity financing, transaction, series of transactions, or merger other than an IPO, de-SPAC transaction, or reverse public merger transaction, to convert the outstanding Notes into shares of common stock ( Optional Conversion ), or to receive a prepayment from the Company for the outstanding principal and interest remaining on the Notes ( Optional Redemption ).
