Forward-Looking Statements

Information set forth in this communication, including financial estimates and statements as to the expected timing, completion and effects of the proposed transaction, constitutes forward-looking statements within the meaning of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. These estimates and statements are subject to risks and uncertainties, and actual results might differ materially.

Such estimates and statements include, but are not limited to, statements about the benefits of the proposed transaction, including future financial and operating results, the combined company’s plans, objectives, expectations and intentions, and other statements that are not historical facts. Some of the forward-looking statements can be identified by the use of forward-looking terms such as “believes,” “expects,” “may,” “will,” “shall,” “should,” “would,” “could,” “seeks,” “aims,” “projects,” “is optimistic,” “intends,” “plans,” “estimates,” “anticipates” or other comparable terms. Such statements are based upon the current beliefs and expectations of the management of Atkore and Prysmian and are subject to known and unknown risks and uncertainties, many of which may be beyond our control. Forward-looking statements are not guarantees of future performance or outcomes and actual performance and outcomes may differ materially from those made in or suggested by the forward-looking statements contained in this communication.

Among the risks and uncertainties that could cause actual results to differ from those described in the forward-looking statements are the following: the completion of the proposed transaction may not occur on the anticipated terms and timing or at all; the occurrence of any event, change or other circumstances that could give rise to the termination of the proposed transaction; the risk that Atkore’s stockholders may not approve the proposed transaction; the risk that the necessary regulatory approvals for the proposed transaction may not be obtained or may be obtained subject to conditions that are not anticipated; risks that any of the closing conditions to the proposed transaction may not be satisfied in a timely manner; risks related to litigation brought in connection with the proposed transaction; risks related to disruption of management time from ongoing business operations due to the proposed transaction; effects of the announcement, pendency or completion of the proposed transaction on Atkore’s ability to retain customers, attract and retain key personnel or employees and maintain relationships with suppliers, agents, distributors, vendors and other business partners, and on Atkore’s operating results and business generally; negative effects of the announcement or the consummation of the proposed transaction on the market price of Atkore’s common stock; risks related to declines in, and uncertainty regarding, the general business and economic conditions in the United States and international markets in which Atkore operates, and the potential impact of general business and economic conditions on Atkore, Prysmian or the proposed transaction; inherent uncertainties involved in the estimates and assumptions used in the preparation of financial projections; and the response of Atkore’s or Prysmian’s management to any of the aforementioned factors.

Discussions of a number of important additional risks and uncertainties are contained in Atkore’s filings with the SEC, including Atkore’s most recent Annual Report on Form 10-K and Quarterly Reports on Form 10-Q, and will be contained in the preliminary proxy statement to be filed by Atkore in connection with the proposed transaction. Neither Atkore nor Prysmian is under any obligation, and each expressly disclaims any obligation, to update, alter, or otherwise revise any forward-looking statements, whether written or oral, that may be made from time to time, whether as a result of new information, future events, or otherwise, except to the extent required by applicable law. Persons reading this communication are cautioned not to place undue reliance on these forward-looking statements which speak only as of the date hereof.
