IBIO · iBio, Inc. · Insider Trading
The latest filing states the doubt was alleviated.
“The history of significant losses, the negative cash flow from operations, and the dependence by the Company on its ability to obtain additional financing to fund its operations in the past raised substantial doubt about the Company's ability to continue as a going concern. In August 2025, the Company closed an underwritten public offering raising gross proceeds of approximately $50 million and in January 2026, the Company raised gross proceeds of approximately $26 million in a private placement. Additionally, the Company received gross proceeds of approximately $33.4 million from the exercise of warrants during the year ended June 30, 2026. Based on the total cash and cash equivalents, and investments in debt securities of approximately $88 million at June 30, 2026, the Company believes that its current cash position is sufficient to fund its operations for at least 12 months from the date of filing this Annual Report on Form 10-K for the year ended June 30, 2026 (the “Annual Report”).”View the 10-K filed Aug 28, 2026
Trades by corporate insiders — officers, directors and holders of more than 10% of the shares — disclosed to the SEC on Forms 4 and 5. Form 3 supplies initial ownership rather than a trade; Form 4 must be filed within two business days of the trade.
