2026-03-04: red flag filed

Open-market purchases and sales (Form 4 codes P and S) by officers, directors and 10% owners, by transaction date, from 2025-12-04 to 2026-04-03. Excludes option exercises, grants, gifts and tax withholding. Amended filings replace the originals; joint filings count once. Foreign private issuers do not file Form 4. Many insider sales are pre-scheduled (10b5-1 plans) and are not by themselves a sign of wrongdoing.

Verified excerpt

"As of December 31, 2024, the Company had concluded that there was substantial doubt about its ability to continue as a going concern primarily due to anticipated operating losses for the foreseeable future since the Company did not yet have regulatory approval to sell any of its product candidates, and the Company continued to incur operating costs to execute its strategic plan, including costs related to research..."

What this means

The filing states that substantial doubt exists about the company's ability to continue as a going concern: it may not have enough cash to last the next 12 months. Expect dilution, debt deals or worse. An auditor's going-concern paragraph is the strongest form of this warning.

Going-concern opinion issued by: Ernst & Young LLP
