Substantial doubt about the company's ability to continue as a going concern.

“the Company 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 on which this Quarterly Report on Form 10-Q is filed. Based on the Company's cash, cash equivalents, and short-term investments as of June 30, 2026, the Company's current and forecasted level of operations, and its forecasted cash flows, the Company's ability to continue as a going concern is dependent upon its ability to obtain the necessary financing to meet its obligations and repay its liabilities arising from normal business operations when they come due. Management plans to provide for the Company's capital requirements through financing or other transactions, and selling shares under the Company's "at the market offering" program. There can be no assurance that the Company will be able to raise additional capital to fund operations with terms acceptable to the Company, or at all.”
