On November 25, 2024, Select Medical Holdings Corporation (“Select”) announced that it had completed the previously announced spin-off of Concentra Group Holdings Parent, Inc. (“Concentra”) by means of a special stock distribution of 104,093,503 shares of Concentra’s common stock that had been owned by Select Medical Corporation to Select’s stockholders as of the close of business on November 18, 2024 (the “Record Date”). The distribution of the special stock distribution (the “Distribution”) was made on November 25, 2024. Based on the number of shares of Select’s common stock outstanding as of the Record Date, Select’s stockholders received 0.806971 shares of Concentra’s common stock for every share of Select’s common stock held as of the close of business on the Record Date. No fractional shares of Concentra’s common stock were distributed. Instead, Select’s stockholders will receive cash in lieu of any fraction of a share of Concentra’s common stock that they otherwise would have received.

Prior to the Distribution, Select owned approximately 81.7% of the outstanding shares of Concentra’s common stock. Following the completion of the Distribution, Select no longer owns any shares of Concentra’s common stock.

A copy of Concentra’s press release announcing the completion of the Distribution is attached as Exhibit 99.1 to this Current Report on Form 8-K, and incorporated herein by reference.
