The Company may not be able to raise sufficient additional capital and may need to tailor its drug candidate development programs based on the amount of funding the Company is able to raise in the future. Nevertheless, there is no assurance that these initiatives will be successful. These condensed consolidated interim financial statements do not give effect to any adjustments to the amounts and classification of assets and liabilities that may be necessary should the Company be unable to continue as a going concern, that may or may not be material to these condensed consolidated interim financial statements.

On January 25, 2013, the Company entered into and closed an exchange agreement (the “Exchange Agreement”), with Del Mar Pharmaceuticals (BC) Ltd. (“Del Mar (BC)”), 0959454 B.C. Ltd.

Going concern and management plans

These condensed consolidated interim financial statements have been prepared on a going concern basis which assumes that the Company will continue its operations for the foreseeable future and contemplates the realization of assets and the settlement of liabilities in the normal course of business.

For the three months ended September 30, 2024, the Company reported a loss of $2,161 and a negative cash flow from operations of $1,889. The Company had an accumulated deficit of $162,052 and had cash and cash equivalents of $3,020 as of

September 30, 2024. The Company is in the clinical stage and has not generated any revenues to date. The Company does not have the prospect of achieving revenues until such time that its product candidate is commercialized, or partnered, which may not ever occur. On August 2, 2022, the Company entered into a stock purchase agreement under which the Company has issued 19 shares of common stock for $2,008 in net proceeds as of September 30, 2024. In addition, on June 28, 2023, the Company announced that it had been awarded approximately $2,000 in grant funding to be received over a two-year period for its REM-001 project. During the year ended June 30, 2024, the Company issued an additional 1,519 shares of common stock for net proceeds of $10,471 from its at-the-market (“ATM”) facility, and announced that it is suspending the development of VAL-083. Even with the proceeds from the grant funding, the stock purchase financing, and the ATM sales, the Company will require additional funding to maintain its clinical trials, research and development projects, and for general operations.

These circumstances indicate substantial doubt exists about the Company’s ability to continue as a going concern within one year from the date of filing of these condensed consolidated interim financial statements.

On October 18, 2024, the Company completed the Merger with TuHURA, on and subject to the terms of the Merger Agreement (Note 11).

Consequently, management is pursuing various financing alternatives to fund the Company’s operations so it can continue as a going concern. Management plans to continue to pursue opportunities to secure the necessary financing through the issue of new equity, including debt, entering into strategic partnership arrangements, and/or pursuing additional strategic transactions. However, the Company’s ability to raise additional capital could be affected by various risks and uncertainties including, but not limited to, global unrest. The Company may not be able to raise sufficient additional capital and may need to tailor its drug candidate development programs based on the amount of funding the Company is able to raise in the future. Nevertheless, there is no assurance that these initiatives will be successful.

These condensed consolidated interim financial statements do not give effect to any adjustments to the amounts and classification of assets and liabilities that may be necessary should the Company be unable to continue as a going concern, that may or may not be material to these condensed consolidated interim financial statements.
