Certain statements made in this Current Report on Form 8-K and Exhibit 99.1 hereto with respect to the Transaction are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Words such as “committed,” “enable,” “expect,” “future,” “will,” “projected” or the negative thereof, and similar expressions identify forward-looking statements.

Forward-looking statements in this Current Report on Form 8-K and Exhibit 99.1 hereto include, but are not limited to, the expected benefits of the Transaction; the Company’s anticipated effects of the Transaction on the Company’s portfolio simplification strategy, streamlining of the Company’s organizational structure, and capital investments in the Company’s remaining businesses; and the Company’s expected use of the net proceeds of the Transaction. These forward-looking statements are made based on current expectations, estimates and projections about the Company’s industry, management’s beliefs and certain assumptions made by management. Such information includes, without limitation, discussions as to guidance and other estimates, perceived opportunities, expectations, beliefs, plans, strategies, goals and objectives concerning the Company’s future financial and operating performance. These statements are not guarantees of future performance and are subject to certain risks, uncertainties and assumptions that are difficult to predict.

Therefore, actual results may differ materially from those expressed or forecasted in such forward-looking statements. Risks and uncertainties include, among other things, risks related to the Transaction, including the risks related to non-achievement of the performance measures for the Additional Consideration and that the Additional Consideration will not be payable; the Company’s ability to realize anticipated benefits of the Transaction, or that such benefits may take longer to realize than expected; diversion of management’s attention; the potential impact of the consummation of the Transaction on relationships with employees, clients and other third parties; the Company’s ability to execute on its strategy, including with respect to portfolio simplification, organizational streamlining, and capital investments, and achieve the benefits it expects therefrom; and the other risks, uncertainties and assumptions discussed in the Company’s filings with the Securities and Exchange Commission, including its most recent reports on Forms 10-K and 10-Q, particularly under the heading “Risk Factors”. Except as required by applicable law, the Company undertakes no obligation to publicly update or revise forward-looking statements, whether as a result of new information, future events or otherwise.
