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

“As of June 30, 2026, the Company incurred a consolidated net loss of $22.3 million and, as of June 30, 2026, had an accumulated deficit in the total amount of $307.1 million. The Company's cash and cash equivalents as of June 30, 2026 totaled $9.4 million and the Company's negative operating cash flow for the six months ended June 30, 2026 was $9.7 million. The Company expects to continue to generate operating losses and negative operating cash flows in the foreseeable future and will require additional funding to support its planned operations. These conditions raise substantial doubt about the Company's ability to continue as a going concern. ... Accordingly, the Company has concluded that substantial doubt exists about its ability to continue as a going concern for at least 12 months from the date of issuance of these consolidated financial statements.”
