Transaction may impact the Company's ability to pursue certain business opportunities; (x) the possibility that the Transaction may be more expensive to complete than anticipated, including as a result of unexpected factors or events; (xi) the occurrence of any event, change or other circumstance that could give rise to the termination of the merger agreement, including in circumstances requiring the Company to pay a termination fee; (xii) the risk that the Company's stock price may decline significantly if the Transaction is not consummated; (xiii) the Company's ability to raise capital and the terms of those financings; (xiv) the risk posed by legislative, regulatory and economic developments affecting the Company's business; (xv) general economic and market developments and conditions, including with respect to federal monetary policy, federal trade policy, sanctions, export restrictions, interest rates, interchange rates, labor shortages, supply chain issues, changes in raw material pricing and availability; energy costs; and environmental matters; (xvi) changes in consumer preferences and demand patterns that could adversely affect the Company's sales, profitability and productivity; (xvii) the effects of animal and food-related health issues on the Company's business; and (xviii) the other risk factors and cautionary statements described in the Company's Annual Report on Form 10-K for the year ended December 31, 2024, the Company's Quarterly Report on Form 10-Q for the quarter ended September 30, 2025, and other documents filed by the Company with the SEC.

Exhibit 99.1

Sealed Air Announces Expiration of "Go-Shop" Period

Transaction is Expected to Close in Mid-2026

CHARLOTTE, N.C., Dec. 17, 2025 - Sealed Air Corporation ("Sealed Air" or the "Company") (NYSE: SEE), a leading global provider of food and protective packaging solutions, today announced the expiration of the 30-day "go-shop" period set forth in the previously announced definitive agreement with funds affiliated with CD&R, a leading private investment firm with deep experience in the industrial and packaging industries (the "Merger Agreement"). Under the terms of the Merger Agreement, funds affiliated with CD&R have agreed to acquire all the outstanding shares of the Company's common stock for $42.15 per share in an all-cash transaction with an enterprise value of $10.3 billion. The "go-shop" period expired at 11:59 p.m. Eastern Time on December 16, 2025.

During the "go-shop" period, and at the direction of the Company's Board of Directors, representatives of Evercore, the Company's financial advisor, actively solicited alternative acquisition proposals from 29 parties, including seven strategic parties and 22 private equity firms. Six of these parties entered into confidentiality agreements and received access to non-public information about Sealed Air. As of the expiration of the "go-shop" period, no party constituted an "Excluded Party" (as defined in the Merger Agreement).

Upon expiration of the "go-shop" period, Sealed Air became subject to the customary "no-shop" provisions that limit the Company's ability to negotiate acquisition proposals with, or provide non-public information to, third parties, subject to exceptions specified in the Merger Agreement including customary "fiduciary out" provisions.

The transaction is expected to close in mid-2026, subject to the receipt of stockholder approval, regulatory clearances, and the satisfaction of other customary closing conditions. Upon closing of the transaction, Sealed Air will become a privately held company, and its common stock will no longer be traded on the New York Stock Exchange (NYSE). The Company will continue to be headquartered in Charlotte, North Carolina.

Advisors

Evercore served as exclusive financial advisor and Latham & Watkins LLP served as legal counsel to Sealed Air.
