This Current Report on Form 8-K furnishes the following information: (i) audited consolidated financial statements of DJO as of December 31, 2016 and 2017 and for the years ended December 31, 2015, 2016 and 2017, attached hereto as Exhibit 99.1; (ii) unaudited consolidated financial statements of DJO as of September 29, 2018 and December 31, 2017 and for the nine months ended September 30, 2017 and September 29, 2018, attached hereto as Exhibit 99.2; and (iii) unaudited pro forma condensed consolidated financial statements as of September 28, 2018 and for the year ended December 31, 2017 and the nine months ended September 28, 2018, attached hereto as Exhibit 99.3.

The Company expects that after the closing of the acquisition, it will file, pursuant to Item 2.01 of Form 8-K, the financial statements and finalized pro forma financial information required by Item 9.01 of Form 8-K.
