On December 12, 2017, NuVasive, Inc. entered into a definitive agreement to acquire SafePassage, a privately-held provider of intraoperative neurophysiological monitoring services. The transaction is expected to close in January 2018 subject to customary closing conditions. A copy of the press release announcing the pending acquisition is furnished as Exhibit 99.1 to this Current Report and incorporated herein by reference.

This Current Report on Form 8-K includes forward-looking statements that are not a description of historical facts and that involve risks, uncertainties, assumptions and other factors which, if they do not materialize or prove correct, could cause NuVasive’s results to differ materially from historical results or those expressed or implied by such forward-looking statements. Forward-looking statements include, but are not limited to, statements about the timing of the anticipated acquisition, the potential benefits and synergies of the anticipated acquisition, including the expected impact on future financial and operating results, and post-acquisition plans and intentions. The forward-looking statements contained herein are based on the current expectations and assumptions of NuVasive and not on historical facts. The following important factors, among others, could cause actual results to differ materially from those set forth in the forward-looking statements: the satisfaction of conditions to closing the agreement, including the risk that any required conditions are not satisfied, are delayed or are subject to unanticipated conditions that could adversely affect the combined company or the expected benefits of the acquisition; the loss of key employees; the risk that the businesses will not be integrated successfully; unexpected variations in market growth and demand for the combined company’s products and technologies; and the risk that benefits and synergies from the acquisition may not be fully realized or may take longer to realize than expected. Additional risks and uncertainties that may affect future results are described in NuVasive’s news releases and periodic filings with the Securities and Exchange Commission.  NuVasive's public filings with the Securities and Exchange Commission are available at www.sec.gov. NuVasive assumes no obligation to update any forward-looking statement to reflect events or circumstances arising after the date on which it was made.
