Item 4 of the Statement is hereby amended and supplemented as follows: On June 18, 2026, the Issuer entered into an Agreement and Plan of Merger (the "Merger Agreement") with AbbVie Inc. ("AbbVie"), Andor LLC, a wholly owned subsidiary of AbbVie ("Parent"), and Andor Merger Co., a wholly owned subsidiary of Parent ("Merger Sub"). Pursuant to the Merger Agreement, on September 3, 2026, Merger Sub merged with and into the Issuer (the "Merger"), with the Issuer surviving the Merger as a wholly owned subsidiary of Parent. Pursuant to the Merger Agreement, at the effective time of the Merger (the "Effective Time"): (i) each share of voting common stock of the Issuer, par value $0.00001 per share, and each share of non-voting common stock of the Issuer, par value $0.00001 per share (each, a "Share"), outstanding immediately prior to the Effective Time, but excluding each Share (A) owned by the Issuer or any of its wholly owned subsidiaries, (B) held by AbbVie, Parent, Merger Sub or any other wholly owned subsidiary of AbbVie, and (C) held by a stockholder who had not voted in favor of the adoption of the Merger Agreement or consented thereto and who was entitled to and properly demanded appraisal, was cancelled and converted into the right to receive $135.11 per Share in cash (the "Merger Consideration"), without interest and subject to any applicable tax withholding; (ii) each option to purchase Shares (each, an "Issuer Option") outstanding immediately prior to the Effective Time (whether vested or unvested) that had an exercise price per Share less than the Merger Consideration was cancelled and converted into the right to receive cash in an amount equal to the product of: (A) the total number of Shares subject to such Issuer Option immediately prior to the Effective Time, multiplied by (B) the excess of (x) the Merger Consideration over (y) the exercise price per Share under such Issuer Option, without interest and subject to any applicable tax withholding. Each Issuer Option outstanding immediately prior to the Effective Time (whether vested or unvested) that had an exercise price per Share greater than or equal to the Merger Consideration was cancelled without any consideration being payable in respect thereof, and had no further force or effect; (iii) each restricted stock unit award of the Issuer (each, a "Issuer RSU") outstanding immediately prior to the Effective Time became fully vested and was cancelled and converted into the right to receive a lump sum cash payment, without interest and subject to any applicable tax withholding, equal to the product of (A) the Merger Consideration, multiplied by (B) the number of Shares subject to such Issuer RSU; (iv) each outstanding restricted stock award of the Issuer (the "Issuer Restricted Stock") outstanding immediately prior to the Effective Time became fully vested and was converted into the right to receive the Merger Consideration for each such share of Issuer Restricted Stock; and (v) each warrant exercisable for Shares (each, a "Issuer Warrant") outstanding immediately prior to the Effective Time, in accordance with its terms, became exercisable by the holder thereof solely for the same Merger Consideration that such holder would have been entitled to receive if such holder had been, immediately prior to the Effective Time, the holder of the number of Shares that were issuable upon exercise in full of such Issuer Warrant without regard to any limitations on exercise contained in such Issuer Warrant. Pursuant to the Merger, the Reporting Persons disposed of an aggregate of 1,750,000 shares of voting common stock, 6,743,321 shares of non-voting common stock, 365,853 pre-funded warrants and stock options exercisable for an aggregate of 80,246 shares for the consideration described above. As a result of the Merger, the common stock ceased to trade on the Nasdaq Global Market prior to the opening of trading on September 4, 2026 and became eligible for delisting from the Nasdaq Global Market and termination of registration pursuant to Rules 12g-4(a)(1) and 12h-3(b)(1)(i) of the Act.
