ADDITIONS TO THE RISK FACTORS DISCLOSED UNDER ITEM 1A – RISK FACTORS OF THE ANNUAL REPORT INCLUDE:\n\n•\nour risk of imminent bankruptcy;\n\n•\nwe need to obtain substantial funding immediately in order to continue operations and our exploration of strategic alternatives;\n\n•\nour suppliers may choose to stop working on programs, change the terms of contracts or terminate contracts for key programs;\n\n•\nour ability to maintain an adequate supply of clinical drug product to complete our ongoing and planned clinical trials;\n\n•\nour suppliers may face challenges due to increased tariffs, geopolitical tensions, regulatory changes, and dependencies in the global supply chain, which could lead to higher costs for imported goods, delays in supply, or interruptions in deliveries;\n\n•\nour suppliers may change the terms of contracts with the company; and\n\n•\nour risk of not being able to meet the continued listing requirements of the TSX and the risk of not being able to meet the listing requirements of Nasdaq as part of the Company's plan to relist on Nasdaq.\n\n \n\nGOING CONCERN RISK\n\nThe Company's financial statements have been prepared on a going concern basis under which the Company is considered to be able to realize its assets and satisfy its liabilities in the ordinary course of business. However, as of the date of this filing, management does not believe that the Company’s cash balance is sufficient to meet its general working capital requirements and contractual obligations for the twelve months subsequent to the issuance of these financial statements. The Company does not have sufficient cash to fund operations and relies on advances made by Hanmi. The Company's future operations are dependent upon the identification and successful completion of equity or debt financing and the achievement of profitable operations at an indeterminate time in the future. There can be no assurances that the Company will be successful in completing additional equity or debt financing or in achieving profitability, or that such additional equity or debt financing will be completed on terms satisfactory to the Company and would be sufficient to satisfy any liquidity concerns related to the Company’s ability to continue as a going concern. Certain adverse conditions and material uncertainties cast doubt upon the ability of the Company to continue as a going concern without a significant restructuring and/or financing. These include:\n\n•\nthe Company has cash-on-hand of approximately $4.5 million as at the date of this filing;\n\n•\nthe Company has a working capital deficiency (excess current liabilities over current assets);\n\n•\nthe Company currently has had no material sales of marketed products and no material sources of cash other than financings, and there can be no assurance as to the Company’s ability to maintain or obtain sufficient financing sources for operations or to meet future obligations.\n\n•\nuncertainty regarding the Company's ability to raise additional capital, which raises substantial doubt about its ability to continue as a going concern without substantial financing.\n\nDue to these adverse conditions and material uncertainties, the use of the going concern assumption in the preparation of the Company’s financial statements may not be appropriate. This could result in material adjustments to the amounts and classifications of assets and liabilities in the Company's financial statements should the Company fail to continue as a going concern. The financial statements do not give effect to any adjustments relating to the carrying values and classification of assets and liabilities that would be necessary should it be unable to continue as a going concern. If the Company is unable to continue as a going concern, it may be forced\n\n \n\n35\n\n \n\n \n\n \n\nto seek relief under applicable bankruptcy and insolvency legislation, which may negatively affect the price and volatility of the Common Shares and any investment in such shares could suffer a significant decline or total loss in value and would subject the Company to additional risks related to such proceedings.\n\n \n\n36"}
