SAN FRANCISCO and VANCOUVER, British Columbia, Oct. 07, 2025 (GLOBE NEWSWIRE) -- Jade Biosciences, Inc. (“the Company” or “Jade”), (Nasdaq: JBIO), a clinical-stage biotechnology company focused on developing best-in-class therapies for autoimmune diseases, today announced that it has entered into a securities purchase agreement for a private investment in public equity (“PIPE”) financing that is expected to result in gross proceeds of approximately $135 million to the Company, before placement agent fees and offering expenses.

The PIPE financing included participation from both new and existing investors, including Janus Henderson Investors, Fairmount, RA Capital Management, Marshall Wace, Aberdeen Investments, Great Point Partners, LLC, Venrock Healthcare Capital Partners, Samsara BioCapital, Avidity Partners, and several other leading healthcare investors.

Pursuant to the terms of the securities purchase agreement, Jade is selling an aggregate of (i) 13,368,164 shares of its common stock (“Common Stock”) at a purchase price of $9.14 per share and (ii) pre-funded warrants to purchase 1,402,092 shares of Common Stock at a price of $9.1399 per pre-funded warrant. The pre-funded warrants have an exercise price of $0.0001 per share and may be exercised at any time after the date of issuance, subject to certain beneficial ownership limitations set by each holder. Following the transaction, there will be approximately 67.4 million shares of the Company’s Common Stock and Common Stock equivalents issued and outstanding, including shares of Common Stock underlying pre-funded warrants and Series A non-voting convertible preferred stock. The PIPE financing is expected to close on or about October 8^th, 2025, subject to satisfaction of customary closing conditions.

The Company intends to use the net proceeds from the PIPE financing, together with its existing cash, cash equivalents, and marketable securities, to fund research and development, general corporate expenses, and working capital needs. Based on current operating plans, the Company expects that its cash, cash equivalents, and marketable securities will fund operations into the first half of 2028.

Jefferies, TD Cowen, Stifel, and Wedbush & Co. are serving as placement agents to Jade for the PIPE financing.

The offer and sale of the foregoing securities are being made in a transaction not involving a public offering and the securities have not been registered under the Securities Act of 1933, as amended, and may not be reoffered or resold in the United States except pursuant to an effective registration statement or an applicable exemption from the registration requirements. Concurrently with the execution of the securities purchase agreement, Jade and the investors entered into a registration rights agreement pursuant to which the Company has agreed to file a registration statement with the Securities and Exchange Commission (the “SEC”) registering the resale of the shares of Common Stock and the Common Stock issuable upon exercise of the pre-funded warrants, in each case sold in the PIPE financing.
