On October 14, 2024, the Elliott Funds, together with EIM, submitted a request to the Secretary of the Issuer (the “Special Meeting Request”) to call a special meeting of shareholders (the “Special Meeting”) for the purposes of (i) repealing each provision of, or amendment to, the Fourth Amended and Restated Bylaws of the Issuer (the “Bylaws”) adopted by the Board without the approval of the shareholders of the Issuer after February 2, 2024 and up to and including the date of the Special Meeting (the “Bylaw Restoration Proposal”), (ii) removing each of Douglas H. Brooks, Eduardo F. Conrado, William H. Cunningham, Thomas W. Gilligan, David P. Hess, Gary C. Kelly, Elaine Mendoza and Jill A. Soltau from the Board as well as any other person or persons elected or appointed to the Board without shareholder approval after September 26, 2024 and up to and including the date of the Special Meeting (other than any Nominee set forth below), effective immediately (the “Removal Proposal”), and (iii) electing each of Michael Cawley, David Cush, Sarah Feinberg, Joshua Gotbaum, David Grissen, Robert Milton, Gregg Saretsky and Patricia Watson (the “Nominees”) to the Board (the “Director Election Proposal”). Attached to the Special Meeting Request was a notice from Elliott to the Issuer of its intention to present the Bylaw Restoration Proposal, the Removal Proposal, and the Director Election Proposal at the Special Meeting. Also on October 14, 2024, EIM issued a press release announcing the submission of the Special Meeting Request. A copy of the press release which is attached hereto as Exhibit 99.8 and is incorporated by reference herein.

In addition, effective as of October 14, 2024, EIM waived Sections 2(b) and 5 of each of the Candidate Agreements with Nancy Killefer and Mr. Sundaram previously disclosed in Item 4 of the Schedule 13D. Accordingly, Mr. Sundaram is no longer a Reporting Person on this Schedule 13D, and he may no longer be deemed to be part of a “group” with EIM and the Nominee Reporting Persons.

By virtue of the Candidate Agreements with each of the Nominee Reporting Persons, EIM and the Nominee Reporting Persons may be deemed to have formed a “group” within the meaning of Section 13(d)(3) of the Exchange Act and the “group” may be deemed to beneficially own an aggregate of 61,179,691 shares of Common Stock, representing approximately 10.2% of the outstanding shares of Common Stock.
