— cleared May 13, 2026
The latest filing states the doubt was alleviated.

The Company expects its cash, cash equivalents and short-term investments will be sufficient to fund its operating expenses and capital expenditure requirements for at least the next twelve months from the date of issuance of these condensed consolidated financial statements.”View the 10-Q filed May 13, 2026
