In connection with making the Incremental Loans under the Amended Credit Agreement, on September 30, 2025, the Issuer and the NEA Lenders entered into a warrantholders agreement (the "2025 Warrantholders Agreement") setting forth the rights and obligations of the NEA Lenders as holders of up to 1,116,765 Warrants (together with all other Warrants previously issued to NEA 18 VGE, NEA 17, NEA 16 and NEA 15, the "Warrants"), subject to the limitations set forth in the 2025 Warrantholders Agreement. The Incremental Loans were made in a single drawing on October 2, 2025, whereby NEA 18 VGE funded a Borrowing (as defined in the Amended Credit Agreement) for $4,141,141.68, NEA 17 funded a Borrowing for $6,211,712.53, NEA 16 funded a Borrowing for $12,423,425.05 and NEA 15 funded a Borrowing for $14,493,995.90. On October 2, 2025, the Issuer issued 124,085 Warrants to NEA 18 VGE, 186,128 Warrants to NEA 17, 372,255 Warrants to NEA 16 and 434,297 Warrants to NEA 15, each at an exercise price of $0.01 per share. The Reporting Persons acquired the securities described in this Amendment No. 9 for investment purposes. Consummation of Merger Pursuant to the Agreement and Plan of Merger (the "Merger Agreement"), dated as of December 23, 2024, by and among the Issuer, NH Holdings 2025, Inc. ("Parent") and NH Holdings Acquisition 2025, Inc. ("Merger Sub"), on October 2, 2025 (the "Closing Date"), Merger Sub merged with and into the Issuer with the Issuer surviving such merger as a wholly owned subsidiary of Parent (the "Merger"). Parent and Merger Sub are affiliated with the NEA Venture Funds. Immediately prior to the effective time of the Merger (the "Effective Time"), the Warrants held by NEA 15, NEA 16, NEA 17 and NEA 18 VGE were net exercised for such number of shares issuable pursuant to the terms of such Warrants based on a fair market value for the shares surrendered of $6.75 per share, the closing market price of the Issuer's common stock on October 1, 2025. In addition, immediately prior to the Effective Time and pursuant to the Rollover Agreements, the NEA Venture Funds, the SPVs and Makhzoumi contributed all of their shares of Common Stock, including the shares of Common Stock acquired upon exercise of the Warrants as described in the immediately preceding paragraph, and NEA 17 and NEA 18 VGE contributed all of their respective shares of Company Preferred Stock to NH Holdings 2025 SPV, L.P. ("Ultimate Parent") in exchange for the issuance to the NEA Venture Funds and SPVs of limited partnership interests in Ultimate Parent. At the Effective Time, each share of Common Stock that was issued and outstanding immediately prior to the Effective Time (other than shares owned immediately prior to the Effective Time by the Issuer, Ultimate Parent, Parent, Merger Sub or any of their respective subsidiaries (including shares contributed to Ultimate Parent prior to the Effective Time pursuant to the Rollover Agreements or other similar agreements)), were cancelled for no consideration, and Dissenting Shares (as defined in the Merger Agreement) were converted into the right to receive $7.33 in cash, without interest and less any applicable withholding taxes. In connection with the closing of the Merger, the Issuer notified the New York Stock Exchange (the "NYSE") of its intent to remove the Issuer's Common Stock from listing on the NYSE and requested that the NYSE (i) suspend trading of the Issuer's Common Stock on the NYSE prior to the opening of trading on the Closing Date and (ii) file a Notification of Removal from Listing and/or Registration on Form 25 with the SEC to delist the Issuer's Common Stock from the NYSE and deregister the Issuer's Common Stock under Section 12(b) of the Exchange Act, which occurred on the Effective Date. Upon effectiveness of the Form 25, the Issuer intends to file with the SEC a Certification and Notice of Termination on Form 15 under the Exchange Act requesting deregistration of the Common Stock and suspension of the Issuer's reporting obligations under Sections 13 and 15(d) of the Exchange Act.
