On December 14, 2015, Newell Rubbermaid Inc., a Delaware corporation (“Newell”), and Jarden Corporation, a Delaware corporation (“Jarden”), issued a joint press release announcing that they had entered into an Agreement and Plan of Merger (the “Merger Agreement”), dated as of December 13, 2015, by and among Newell, Jarden, NCPF Acquisition Corp. I, a Delaware corporation and a wholly-owned subsidiary of Newell (“Newell Merger Sub”), and NCPF Acquisition Corp. II, a Delaware corporation and a wholly-owned subsidiary of Newell (“Successor Merger Sub”), pursuant to which Newell will combine with Jarden in a series of merger transactions (the “Combination”).

Newell Merger Sub will merge with and into Jarden (the “Jarden Merger”), with Jarden continuing as the surviving corporation and as a wholly-owned subsidiary of Newell. Immediately following the effectiveness of the Jarden Merger, Jarden will merge with and into Successor Merger Sub, with Successor Merger Sub continuing as the surviving corporation (the “Successor Merger Sub Merger” and, together with the Jarden Merger, the “Combined Mergers”). As a result of the Combined Mergers, the Successor Merger Sub with the legacy business of Jarden will become a direct wholly-owned subsidiary of Newell. Following the consummation of the Combination, Newell will change its name to Newell Brands Inc.

Newell and Jarden will be providing supplemental information regarding the Combination through a teleconference with analysts and investors.

Caution Concerning Forward Looking Statements

Statements that are not historical in nature constitute forward-looking statements. These forward-looking statements relate to information or assumptions about the timing of completion of the proposed combination, the expected benefits of the proposed combination, management’s plans, projections and objectives for future operations, scale and performance, integration plans and expected synergies therefrom, and anticipated future financial and operating performance results, including operating margin or gross margin capital and other expenditures, cash flow, dividends, restructuring and other project costs, costs and cost savings, and debt ratings. These statements are accompanied by words such as “anticipate,” “expect,” “project,” “will,” “believe,” “estimate” and similar expressions. Such expectations are based upon certain preliminary information, internal estimates, and management assumptions, expectations, and plans, and are subject to a number of risks and uncertainties inherent in projecting future conditions, events, and results. Actual results could differ materially from those expressed or implied in the forward-looking statements if one or more of the underlying assumptions or expectations prove to be inaccurate or are unrealized. Important factors that could cause actual results to differ materially from those suggested by the forward-looking statements include, but are not limited to, the occurrence of any event, change or other circumstances that could give rise to the termination of the merger agreement; the risk that the necessary shareholder approvals may not be obtained; the risk that the necessary regulatory approvals may not be obtained or may be obtained subject to conditions that are not anticipated; the risk that the proposed combination will not be consummated in a timely manner; risks that any of the closing conditions to the proposed combination may not be satisfied or may not be satisfied in a timely manner; risks related to disruption of management time from ongoing business operations due to the proposed combination; the risk that we are unable to retain our investment grade rating; failure to realize the benefits expected from the proposed combination; failure to promptly and effectively integrate the combination; and the effect of the announcement of the proposed combination on the ability of Newell Rubbermaid to retain customers and retain and hire key personnel, maintain relationships with suppliers, on its operating results and businesses generally and those factors listed in Newell Rubbermaid’s most recently filed Quarterly Report on Form 10-Q and exhibit 99.1 thereto, in each case, filed with the Securities and Exchange Commission (“SEC”). Changes in such assumptions or factors could produce significantly different results. The information contained in this Current Report on Form 8-K is as of the date indicated.
