Item 8.01 Other Events

On July 9, 2015, the Board of Directors of Sealed Air Corporation (the “Company”) authorized a new stock repurchase program (the “Program”) to repurchase up to $1.5 billion of the Company’s issued and outstanding common stock. A copy of the press release, dated July 14, 2015, announcing the Program is attached as Exhibit 99.1 hereto and is incorporated herein by reference. Repurchases under the Program may be effected through privately negotiated transactions, open market repurchases, accelerated stock repurchase programs and/or issuer self-tender offers. The timing and exact amount of repurchases will depend on such factors as levels of cash generation from operations, cash requirements for investment in the Company’s business, repayment of debt, current stock price, market conditions and other factors. The Company’s repurchase program may be suspended, discontinued or resumed at any time. Shares that are repurchased pursuant to the Program will be held as treasury shares. The Program replaces the previous stock repurchase program approved in August 2007.
