Item 1.01 Entry Into a Material Definitive Agreement.

Share Purchase Agreement

On February 24, 2015, Genesee & Wyoming Inc., a Delaware corporation (“GWI”), GWI UK Acquisition Company Limited, a newly-established, wholly-owned subsidiary of GWI (the “Purchaser”), RailInvest Investments Limited (the “Institutional Seller”), and certain management sellers (the “Management Sellers” and, together with the Institutional Seller, the “Sellers”), entered into a Share Purchase Agreement (“SPA”) pursuant to which Purchaser agreed to acquire the outstanding share capital of RailInvest Holding Company Limited, the parent company of Freightliner Group Limited (“Freightliner”) for cash consideration of approximately £490 million (US$755 million at current exchange rates), and to assume approximately £8.5 million (US$13 million) in net debt and capitalized leases (the “Transaction”). Following the consummation of the Transaction, GWI, through the Purchaser, will own approximately 95% of the shares of Freightliner, with members of the existing Freightliner management team retaining an approximate 5% ownership interest with GWI to own 100% by mid 2020. GWI has agreed to provide a guaranty in favor of the Sellers of the Purchaser’s obligations under the SPA. The Transaction is expected to be consummated during the first quarter of 2015.

The SPA contains customary provisions, including without limitation, pre-closing adjustments to the cash consideration, and post-closing indemnities, limitations on non-ordinary course dividends and other distributions; interim operating covenants requiring the Sellers to operate the business prior to closing in accordance with past practice; certain fundamental representations and warranties from the Institutional Seller and Management Sellers and certain business representations and warranties from the Management Sellers for the benefit of Purchaser and GWI, subject, in each case, to ordinary course limitations, exceptions and caps, as applicable.

GWI expects to fund the Transaction through an amendment to its existing credit facility, which amendment is expected to allow for the issuance of approximately $650 million in new term loans, with the remainder of the cash consideration drawn under GWI’s existing revolving credit facility. In the event GWI does not amend its existing credit facility, GWI has entered into a Debt Commitment Letter, described in Item 2.0.3 below, to finance the Transaction and pay fees, costs and expenses related to the Transaction.

Item 2.03 Creation of a Direct Financial Obligation or an Obligation under on Off-Balance Sheet Arrangement of a Registrant.

Commitment Letter

Concurrently, and in connection, with entering into the SPA, GWI entered into a commitment letter for debt financing (the “Debt Commitment Letter”) with Bank of America, N.A. (“Bank of America”) and Merrill Lynch, Pierce, Fenner & Smith Incorporated (or any of its designated affiliates, “Merrill Lynch”), pursuant to which, subject to the conditions set forth therein, Bank of America has committed to provide to GWI up to $300 million in incremental senior secured credit facilities in the form of a term loan facility (the “Incremental Term Loan Facility”). The terms of the Incremental Term Loan Facility will be substantially in accordance with the summary of the terms of GWI’s existing credit facility set forth in Item 1.01 of GWI’s Current Report on Form 8-K filed on May 30, 2014.

Merrill Lynch will act as sole and exclusive lead arranger and sole and exclusive bookrunning manager for the Incremental Term Loan Facility, subject to the rights of GWI to name certain additional lead arrangers and bookrunning managers. Bank of America and Merrill Lynch and any additional lead arrangers and bookrunning managers and certain of each of their affiliates may have engaged in, and may in the future engage in, investment banking and other commercial dealings in the ordinary course of business with us or our affiliates. They have received, or may in the future receive, customary fees and commissions for these transactions.

The foregoing description of the SPA and the Debt Commitment Letter and the transactions contemplated thereby do not purport to be complete and are subject to, and qualified in its entirety by, the full text of the SPA and the Debt Commitment Letter, copies of each of which are attached hereto as Exhibits 10.1 and 10.2, respectively, which are incorporated herein by reference.
