Equity capital markets analyst

Jade Biosciences secures a $45M private equity financing to support R&D and operations.

Jade Biosciences has arranged a private placement of 3,214,286 common shares at $14.00 per share, for expected gross proceeds of about $45 million before expenses. This adds a meaningful amount of new equity capital that can help fund its research programs, day-to-day operations, and working capital needs.

The private placement is structured under Section 4(a)(2) and Rule 506 of Regulation D, with the purchaser represented as an accredited investor or qualified institutional buyer and no general solicitation used. The company also granted registration rights, agreeing to file a resale registration statement within 45 days after closing and to use its reasonable best efforts to obtain effectiveness within 75 days, with specified penalties if these milestones are not met.

Because this is an unregistered offering, the shares are initially restricted, but the agreed registration rights outline a path to later resales. Overall, the transaction trades additional equity issuance for a substantial cash infusion, and its long-term impact will depend on how effectively the $45 million is deployed into research and corporate initiatives described by the company.

The Private Placement is being conducted in accordance with applicable Nasdaq rules.

The Company intends to use the net proceeds from the Private Placement to fund research and development, general corporate expenses and working capital needs.

Also on December 13, 2025, the Company entered into a Registration Rights Agreement (the “Registration Rights Agreement”) with the Purchaser, which provides that the Company will register the resale of the Shares. The Company is required to prepare and file a registration statement with the Securities and Exchange Commission (or amend any existing registration statement) no later than 45 days following the Closing, and to use its reasonable best efforts to have the registration statement declared effective 75 days thereafter, subject to certain exceptions and specified penalties if timely effectiveness is not achieved.

The Purchase Agreement contains customary representations, warranties and agreements by the Company, indemnification obligations of the Company and the Purchaser, including for liabilities under the Securities Act of 1933, as amended (the “Securities Act”), and other obligations of the parties.

Investors should not rely on the representations, warranties and covenants or any description thereof as characterizations of the actual state of facts or condition of the Company.

The Private Placement is exempt from the registration requirements of the Securities Act pursuant to the exemption for transactions by an issuer not involving any public offering under Section 4(a)(2) of the Securities Act and/or Rule 506 of Regulation D of the Securities Act and in reliance on similar exemptions under applicable state laws. The Purchaser represented that it was an accredited investor or qualified institutional buyer within the meaning of rules promulgated under the Securities Act and were acquiring the securities for investment only and with no present intention of distributing any of such securities or any arrangement or understanding regarding the distribution thereof. The securities were offered without any general solicitation by the Company or its representatives.
