This Amendment No. 7 ("Amendment No. 7") amends the statement on Schedule 13D filed with the SEC on September 27, 2024 (as amended from time to time, the "Schedule 13D") with respect to the Shares of the Issuer.

Capitalized terms used herein and not otherwise defined in this Amendment No. 7 have the meanings set forth in the Schedule 13D.

**Item 4. Purpose of Transaction**

Item 4 is hereby amended and supplemented as follows:

On March 26, 2026, the Reporting Person entered into a Nomination and Support Agreement with the Issuer (the "Nomination and Support Agreement"), pursuant to which, among other things, the Issuer agreed to nominate Kevin Galligan ("Mr. Galligan") to the Issuer's slate of recommended nominees standing for election at its 2026 annual meeting of stockholder and to solicit proxies in support of his election. Pursuant to the Nomination and Support Agreement, the Reporting Person is now permitted to acquire beneficial ownership of up to 19.9% of the Issuer's Shares, and the Board has approved any such acquisition for the purposes of certain provisions of the Delaware General Corporation Law. The summary of the Nomination and Support Agreement does not purport to be complete and the full text of the Nomination and Support Agreement is included as Exhibit 99.4 and is incorporated by reference herein.

**Item 5. Interest in Securities of the Issuer**

**(a)**
Item 5(a) is hereby amended and restated in its entirety as follows:

The aggregate percentage of Shares reported to be beneficially owned by the Reporting Person is based upon 65,893,112 Shares outstanding as of February 13, 2026, as reported in the Issuer's Annual Report on Form 10-K for the fiscal year ended December 31, 2025, filed with the SEC on February 19, 2026.

As of the date hereof, JANA may be deemed to beneficially own 6,760,149 Shares, representing approximately 10.3% of the Shares outstanding.  This includes 15,320 shares of restricted stock ("RSUs") granted to Mr. Galligan on April 22, 2025 (the "April 2025 RSUs"), and 1,176 RSUs granted to Mr. Galligan on June 11, 2025 (the "June 2025" RSUs"), for his service on the Board. The April 2025 RSUs vests in three substantially equal annual installments beginning on April 22, 2026, in each case subject to Mr. Galligan's continued service with the Issuer through the applicable vesting date. The June 2025 RSUs vest in full on the earlier of: (i) the date of the Issuer's next annual meeting of stockholders held after the date of the grant or (ii) the first anniversary of the date of grant, in each case subject to Mr. Galligan's continued service with the Issuer through the applicable vesting date. Mr. Galligan has assigned all rights to any Shares issuable pursuant to the grants to the Reporting Person. Pursuant to the assignment, settlement of the award on vesting will be made to the Reporting Person.
