Going-concern doubt — flagged Aug 12, 2026

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

“Our existing cash, cash equivalents and short-term investments as of June 30, 2026 will not be sufficient to fund our planned operations for at least the next twelve months from the date of issuance of these financial statements. These conditions raise substantial doubt about our ability to continue as a going concern for at least 12 months after the issuance of the accompanying condensed consolidated financial statements.”
