Item 1.01. Entry into a Material Definitive Agreement.

The information contained in Item 2.01 is incorporated by reference herein.

Item 2.01. Completion of Acquisition or Disposition of Assets.

On May 14, 2014, Navigant Consulting, Inc. (“Navigant”) acquired Cymetrix Corporation (“Cymetrix”), a privately held revenue cycle management firm that specializes in providing outsourcing services to hospital and healthcare networks. The acquisition was effected pursuant to an Agreement and Plan of Merger (the “Merger Agreement”), dated as of May 14, 2014, among Navigant, Bobcat Acquisition Corporation, a wholly-owned subsidiary of Navigant (“Merger Sub”), Cymetrix and certain securityholders of Cymetrix. Pursuant to the Merger Agreement, Merger Sub merged with and into Cymetrix (the “Merger”), with Cymetrix continuing as the surviving corporation and a wholly-owned subsidiary of Navigant.

The aggregate purchase price to be paid by Navigant in connection with the Merger is comprised of (a) approximately $75.0 million in cash paid at closing, subject to a post-closing working capital adjustment, and (b) a deferred contingent cash payment of up to $25.0 million based on the achievement of certain revenue and EBITDA performance targets by Cymetrix during the period beginning on November 1, 2014 and ending on October 31, 2015.

The Merger Agreement contains customary representations, warranties and covenants, as well as customary indemnification obligations. A portion of the purchase price ($7.5 million in cash) was placed in escrow to secure the indemnification obligations under the Merger Agreement.

A copy of the Merger Agreement is attached hereto as Exhibit 2.1 and is incorporated by reference herein. A copy of the press release dated May 14, 2014 announcing the transaction is attached hereto as Exhibit 99.1 and is incorporated by reference herein.
