Item 5. | Interest in Securities of the Issuer | |
(a) | Part (a) of Item 5 of the Schedule 13D is hereby amended and supplemented by adding the following:
(a) As of 4:00 pm, New York City time, on May 1, 2025, the Reporting Persons beneficially owned 31,867,800 Shares, representing approximately 20.23% of the Issuer's outstanding Shares (calculated based on 157,557,812 Shares outstanding as of as of April 29, 2025, as reported by the Issuer in its Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2025 (the "Form 10-Q")). The percentage of the Shares beneficially owned by the Reporting Persons increased by approximately one percent (1%) in the aggregate since the filing of Amendment No. 12, based on the number of outstanding Shares disclosed in the Form 10-Q. | |
(b) | Part (b) of Item 5 of the Schedule 13D is hereby amended and restated with the following:
(b) Trian AM Holdco beneficially and directly owns and has sole voting power and sole dispositive power with regard to 31,867,800 Shares, except to the extent that other Reporting Persons as described in this Item 5(b) may be deemed to have shared voting power and shared dispositive power with regard to such Shares.
Each of Trian Management, Trian Management GP, Nelson Peltz and Peter W. May, by virtue of their relationships with Trian AM Holdco (as discussed in Item 2 above), may be deemed to have shared voting power and shared dispositive power with regard to, and therefore may be deemed to beneficially own (as that term is defined in Rule 13d-3), the Shares that Trian AM Holdco directly and beneficially owns. Each of Trian Management, Trian Management GP, Nelson Peltz and Peter W. May disclaim beneficial ownership of such Shares for all other purposes. | |
(c) | Part (c) of Item 5 of the Schedule 13D is hereby amended and supplemented by adding the following:
(c) There have been no new transactions by the Reporting Persons during the sixty days preceding the filing of this Amendment No. 13. |
