LLC, Guggenheim Securities, LLC and Cantor Fitzgerald & Co., as representatives of the several underwriters named in Schedule 1 thereto (the “Underwriters”), pursuant to which the Company agreed to issue and sell in an underwritten public offering (the “Offering”) an aggregate of 7,954,546 shares of its common stock, par value $0.0001 per share, at a price to the public of $44.00 per share. The Offering is made pursuant to an effective registration statement on Form S-3 (File No. 333-287104) and a related prospectus and prospectus supplement, in each case filed with the Securities and Exchange Commission (the “SEC”). The Company also granted the Underwriters an option, exercisable for a period of 30 days, to purchase up to an additional 1,193,181 shares of common stock from the Company (the “Option”). All of the shares of common stock in the Offering are being sold by the Company. The Company estimates that the gross proceeds from the Offering will be approximately $350.0 million, before deducting underwriting discounts and commissions and estimated offering expenses, and assuming no exercise of the Option by the Underwriters. The Offering is scheduled to close on or about June 26, 2025, subject to customary closing conditions.

The Underwriting Agreement contains customary representations, warranties, covenants and agreements by the Company, customary conditions to closing, indemnification obligations of the Company and the Underwriters, including for liabilities under the Securities Act of 1933, as amended, 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.

A copy of the Underwriting Agreement is filed as Exhibit 1.1 to this Current Report on Form 8-K and is incorporated herein by reference.
