The securities purchased by each of Starboard V&O Fund, Starboard S LLC, Starboard C LP, Starboard L Master, Starboard X Master and Starboard Value LP through the Starboard Value LP Account were purchased with working capital pursuant to the terms of the various agreements entered into with the Issuer, as further described in Item 4 below.

The aggregate purchase price of the 6,112,360 Shares beneficially owned by Starboard S LLC is approximately $23,810,114, excluding brokerage commissions. The aggregate purchase price of the 3,545,169 Shares beneficially owned by Starboard C LP is approximately $13,809,867, excluding brokerage commissions.

The 45,394 Shares beneficially owned directly by Mr. Molinelli were awarded to him in his capacity as a director of the Issuer. 164,892 of the Shares beneficially owned directly by Mr. Sagal were awarded to him in his capacity as a director of the Issuer. 24,335 of the Shares beneficially owned directly by Mr. Sagal were purchased with personal funds in connection with Mr. Sagal’s exercise of certain subscriptions rights in connection with the Public Rights Offering (as defined and described in Item 4 of Amendment No. 1 to the Schedule 13D). The aggregate purchase price of the 24,335 Shares beneficially owned by Mr. Sagal pursuant to his exercise of subscription rights in the Public Rights Offering is $127,759.

Item 4.

Purpose of Transaction.

Item 4 is hereby amended to add the following:

As previously disclosed, on October 30, 2022, Starboard Value LP and certain of its affiliates (collectively, “Starboard”) entered into a Recapitalization Agreement (the “Recapitalization Agreement”) with the Issuer, pursuant to which, among other things, Starboard and the Issuer agreed to enter into a series of transactions to restructure Starboard’s existing investments in the Issuer.

As contemplated by the Recapitalization Agreement, on June 30, 2023, the Issuer filed its Amended and Restated Certificate of Designations, Preferences and Rights of Series A Convertible Preferred Stock (the “Certificate of Designations”), which was previously approved by the Issuer’s stockholders at the Issuer’s annual meeting of stockholders held on May 16, 2023, to remove the 4.89% blocker provision contained therein. In accordance with the terms of the Certificate of Designations and the Recapitalization Agreement, on July 13, 2023, Starboard converted an aggregate amount of 350,000 shares of Series A Convertible Preferred Stock into 9,616,746 Shares, including 27,704 Shares issued in respect of accrued and unpaid dividends.

CUSIP No. 003881307

Further to the terms of the Recapitalization Agreement and in accordance with the terms of the Issuer’s Series B Warrants (the “Series B Warrants”), on July 13, 2023, Starboard also irrevocably exercised 31,506,849 of the Series B Warrants through a combination of a “Note Cancellation” and a “Limited Cash Exercise” (each as defined in the Series B Warrants), as determined by Starboard, for an aggregate total of 31,506,849 Shares (the “Series B Warrants Exercise”). Pursuant to the Series B Warrants Exercise, the Issuer cancelled $60 million aggregate principal amount of senior secured notes held by Starboard and received aggregate gross proceeds of approximately $55 million.

The foregoing description of the Certificate of Designations is qualified in its entirety by reference to the full text of the Certificate of Designations, which is included as Appendix A to the Issuer’s Definitive Proxy Statement filed with the Securities and Exchange Commission (the “SEC”) on April 17, 2023, and included as Exhibit 99.1 hereto.

Item 5.

Interest in Securities of the Issuer.

Items 5(a) – (c) are hereby amended and restated as follows:

The aggregate percentage of Shares reported owned by each person named herein is based upon 99,886,322 Shares outstanding, as of July 13, 2023, which is the total number of Shares outstanding as reported in the Issuer’s Current Report on Form 8-K filed with the SEC on July 17, 2023.
