(“Jade” or the “Company”) entered into an underwriting agreement (the “Underwriting Agreement”) with Jefferies LLC, TD Securities (USA) LLC and UBS Securities LLC, as representatives of the several underwriters named therein (collectively, the “Underwriters”), relating to the issuance and sale of 10,000,000 shares (the “Shares”) of the Company’s common stock, par value $0.0001 per share (the “Common Stock”), at an offering price to the public of $15.00 per share. The Underwriters have agreed to purchase the Shares from the Company pursuant to the Underwriting Agreement at a price of $14.10 per share. In addition, under the terms of the Underwriting Agreement, the Company has granted the Underwriters a 30-day option to purchase up to 1,500,000 additional shares of Common Stock at the public offering price, less underwriting discounts and commissions. The net proceeds to the Company from this offering are expected to be approximately $140.3 million, or approximately $161.5 million if the Underwriters’ option to purchase additional shares is exercised in full, after deducting underwriting discounts and commissions and estimated offering expenses. The offering is expected to close on June 5, 2026, subject to the satisfaction of customary closing conditions.\n\nThe offering is being made pursuant to the Company’s shelf registration statement on Form S-3 (Registration Statement No. 333-295662), including the prospectus included therein, previously filed with and declared effective by the Securities and Exchange Commission (the “SEC”), and a prospectus supplement and the accompanying prospectus filed with the SEC on June 3, 2026 pursuant to Rule 424(b) under the Securities Act of 1933, as amended (the “Securities Act”).\n\nThe Underwriting Agreement contains customary representations, warranties and agreements by the Company, customary conditions to closing, indemnification obligations of the Company and the Underwriters, including for liabilities under the Securities Act, other obligations of the parties and termination provisions. The representations, warranties and covenants contained in the Underwriting Agreement were made only for purposes of such agreement and as of specific dates, were solely for the benefit of the parties to such agreement, and may be subject to limitations agreed upon by the contracting parties.\n\nThe foregoing description of the Underwriting Agreement is not complete and is qualified in its entirety by reference to the full text of the Underwriting Agreement, a copy of which is filed as Exhibit 1.1 to this report and which is incorporated by reference herein.
