These statements are not guarantees of future performance and involve certain risks, uncertainties and assumptions that are difficult to predict.

For example, these forward-looking statements could be affected by factors including, without limitation:

risks associated with the ability to consummate the merger and the timing of the closing of the merger; the failure to obtain the necessary debt financing arrangements set forth in the commitment letter received in connection with the merger; the interest rate on any borrowings incurred in connection with the transaction; the impact of the indebtedness incurred to finance the transaction; the ability to successfully integrate our operations and employees; the ability to realize anticipated benefits and synergies of the transaction; the potential impact of announcement of the transaction or consummation of the transaction on relationships, including with employees, customers and competitors; the outcome of any legal proceedings that have been or may be instituted against NN following announcement of the transaction; the ability to retain key personnel; the amount of the costs, fees, expenses and charges related to the merger and the actual terms of the financings that will be obtained for the merger; and changes in financial markets, interest rates and foreign currency exchange rates.
