Item 1.01 Entry into a Material Definitive Agreement

As previously reported, on October 25, 2016, the Company issued a press release that provided an update on the Company’s acquisition of Faiveley Transport, S.A. (“Faiveley”). The Company anticipates completing the purchase of the Faiveley family shares, which equals 51% of Faiveley’s outstanding shares, in November, subject to receiving the remaining regulatory approvals. At such point, Wabtec will issue a tender offer for the remaining public shares of Faiveley. The terms of the Faiveley transaction were modified on October 24, 2016. The modified terms include: (i) the terms of the material agreements have been extended to December 31, 2016 from the original date of October 27, 2016 (the Company can elect to further extend the term to March 21, 2017); (ii) the Company will acquire the Faiveley family shares for €100 per share with between 25% to 45% of the consideration to be paid in cash, with the remaining consideration consisting of between 4.8 million to 6.3 million shares of the Company’s common stock, depending on the percentage of cash the family chooses to take; (iii) public shareholders of Faiveley can elect to take 100% of the consideration in cash at €100 per share, or a portion in the Company’s common shares, capped at the same percentage of consideration chosen by the Faiveley family; and (iv) no Company preferred shares will be issued as part of the transaction.

The foregoing description of the amendments to the Share Purchase Agreement, Tender Offer Agreement and Shareholders Agreement does not purport to be complete and is qualified in its entirety by reference to the actual terms of such amendments, copies of which are attached hereto as Exhibit 2.1 through 2.3, and which are incorporated herein by reference.
