Going-concern doubt
— cleared Aug 6, 2026
The latest filing states the doubt was alleviated.
“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 that these condensed consolidated financial statements are issued. The Company believes that its existing cash, cash equivalents and marketable securities of $268.3 million as of June 30, 2026, will be sufficient to allow the Company to fund operations beyond twelve months from the date that the financial statements are issued.”View the 10-Q filed Aug 6, 2026
