Item 2.01. Completion of Acquisition or Disposition of Assets.

On February 3, 2017, Westinghouse Air Brake Technologies Corporation (the “Company”) announced the closing of the previously disclosed tender to purchase the ordinary shares of Faiveley Transport, S.A. (“Faiveley Transport”) not already acquired from Financière Faiveley S.A., Famille Faiveley Participations, Mr. François Faiveley and Mr. Erwan Faiveley (collectively, the “Sellers”) pursuant to the Share Purchase Agreement, dated October 6, 2015, by and among the Company, Wabtec France and the Sellers, as amended.

The cash and exchange tender offer (the “Offer”) was open from December 27, 2016 through January 30, 2017. The Company, indirectly through Wabtec France, acquired a total of 4,065,860 Faiveley Transport shares, including (a) 3,816,195 shares pursuant to the cash offer for €100 per share, and (b) 249,665 shares pursuant to the exchange offer for 15 shares of common stock, par value $0.01 per share of the Company, for every 13 ordinary shares of Faiveley Transport, or an aggregate of 288,075 shares of Company common stock.

Taking into account the shares that it already held , Wabtec France therefore holds 78.17% of the share capital and 76.26% of the voting rights of Faiveley Transport.

In accordance with the applicable regulation in France, the Offer will be reopened. In the event that, following the subsequent Offer, the minority shareholders represent less than 5% of the share capital or voting rights of Faiveley Transport, Wabtec France has the intention to implement, at the latest within three months of the closing of the subsequent Offer, a mandatory squeeze-out procedure with respect to the Faiveley Transport shares which have not been tendered to the subsequent Offer.

Item 3.02. Unregistered Sales of Equity Securities.

The Company common stock issued in connection with the tender described in Item 2.01, and incorporated herein by reference, was issued in reliance on an exemption from registration set forth in Rule 802 under the Securities Act of 1933, as amended.

Item 8.01. Other Events.

On February 3, 2017 the Company issued a press release regarding, among other things, the matters described herein. A copy of the press release is attached to this report as Exhibit 99.1.
