Liquidity

The accompanying unaudited condensed interim consolidated financial statements (the “Financial Statements”) have been prepared on the basis of continuity of operations, realization of assets and the satisfaction of liabilities and commitments in the ordinary course of business.

Pursuant to the requirements of Accounting Standard Codification (“ASC”) 205-40, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern, the Company has evaluated whether there are conditions and events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date the accompanying Financial Statements are issued. The Company had an accumulated deficit of $126.8 million as of September 30, 2025. Further, the Company incurred a net loss of $7.7 million and experienced negative cash flows from operations of $11.6 million for the nine months ended September 30, 2025. Based on the Company’s current operating plan, it estimates that its existing cash, cash equivalents and restricted cash of $16.9 million as of September 30, 2025 will be sufficient to enable the Company to fund its operating expenses and capital requirements through at least the next 12 months from the issuance of these Financial Statements.

While the Company believes its capital resources are sufficient to fund the Company’s on-going operations for the next 12 months from the issuance date of the Financial Statements, the Company’s liquidity could be materially affected over this period by: (1) its ability to raise additional capital through equity offerings, debt financings, or other non-dilutive third-party funding; (2) costs associated with new or existing strategic alliances, or licensing and collaboration arrangements; (3) negative regulatory events or unanticipated costs related to the DRP or stenoparib; (4) any other unanticipated material negative events or costs. One or more of these events or costs could materially affect the Company’s liquidity. If the Company is unable to meet its obligations when they become due, the Company may have to delay expenditures, reduce the scope of its research and development programs, or make significant changes to its operating plan.
