Forward-Looking Statements

This communication contains forward-looking statements (including within the meaning of the Private Securities Litigation Reform Act of 1995) concerning the Company, the Acquisition and other matters. These statements may discuss goals, intentions and expectations as to future plans, trends, events, results of operations or financial condition, or otherwise, based on current beliefs of the management of the Company as well as assumptions made by, and information currently available to, such management. Forward-looking statements may be accompanied by words such as “aim,” “anticipate,” “believe,” “plan,” “could,” “would,” “should,” “estimate,” “expect,” “forecast,” “future,” “guidance,” “intend,” “may,” “will,” “possible,” “potential,” “predict,” “project” or similar words, phrases or expressions. These forward-looking statements are subject to various risks and uncertainties, many of which are outside the control of the Company. Therefore, you should not place undue reliance on such statements. Factors that could cause actual results to differ materially from those in the forward-looking statements include the risk that the BNS Business will not be integrated successfully into the Company or that the Company will not realize estimated cost savings, synergies and growth or that such benefits may take longer to realize than expected; failure by the Company to realize anticipated benefits of the acquisition; risks relating to unanticipated costs of integration; risks from relying on TE Connectivity for various critical transaction services for an extended period; reductions in customer spending and/or a slowdown in customer payments; failure to manage potential conflicts of interest between or among customers; unanticipated changes relating to competitive factors in the telecommunications industry; ability to hire and retain key personnel; the potential impact of consummation of the Acquisition on relationships with third parties, including customers, employees and competitors; ability to attract new customers and retain existing customers in the manner anticipated; changes in legislation or governmental regulations affecting the Company and the BNS Business; international, national or local economic, social or political conditions that could adversely affect the Company, the BNS Business or their customers; risks associated with assumptions made in connection with the critical accounting estimates, including segment presentation, and legal proceedings of the Company and/or the BNS Business; and the international operations of the Company and/or the BNS Business, which are subject to the risks of currency fluctuations and foreign exchange controls. The foregoing list of factors is not exhaustive. You should carefully consider the foregoing factors and the other risks and uncertainties that affect the businesses of the Company and/or the BNS Business, including those described in each of the Company’s and TE Connectivity’s Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and other documents filed from time to time with the Securities and Exchange Commission.
