AND COMMERCIAL PAPER PROGRAM

Approximately 96% of Total Outstanding Senior Notes Tendered

Kansas City, Missouri, December 9, 2015 — Kansas City Southern (“KCS”) (NYSE: KSU) announced today the expiration and final results of the previously announced exchange offers (the “Exchange Offers”) for any and all outstanding notes of the series set forth on the table below issued by its wholly-owned subsidiaries (i) The Kansas City Southern Railway Company (“KCSR”) and (ii) Kansas City Southern de México, S.A. de C.V. (“KCSM”) (collectively, the “Existing Notes”) and the related consent solicitations (the “Consent Solicitations”). The Consent Solicitations sought consents (the “Consents”) on behalf of KCSR or KCSM, as applicable, from each Eligible Holder (as defined below) of the Existing Notes relating to certain proposed amendments (the “Proposed Amendments”) to the indentures governing the Existing Notes (collectively, the “Existing Indentures”).

The results of the Exchange Offers and Consent Solicitations as of 11:59 p.m., New York City time, on December 8, 2015 (the “Expiration Date”), are as follows:

On December 9, 2015, KCS accepted for purchase, and paid the applicable consideration for, all Existing Notes that were validly tendered (and not validly withdrawn) in the Exchange Offers on or prior to the Expiration Date, plus accrued and unpaid interest. The consummation of the Exchange Offers and Consent Solicitations was subject to and conditional upon, among other things, KCS entering into a new $800.0 million revolving credit facility (the “KCS Revolving Credit Facility”), which occurred on December 9, 2015. The KCS Revolving Credit Facility, in turn, is expected to be used primarily to support issuance of commercial paper by KCS under a new $800.0 million commercial paper program entered into on December 9, 2015.

The Exchange Offers and Consent Solicitations were made, and the KCS Notes were offered and issued, only (a) in the United States to holders of Existing Notes who are “qualified institutional buyers” (as defined in Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”)) and (b) outside the United States to holders of Existing Notes who are persons other than U.S. persons in reliance upon Regulation S under the Securities Act (collectively, “Eligible Holders”).

KCS retained D.F. King & Co., Inc. to serve as the information agent and exchange agent for the Exchange Offers and Consent Solicitations.

The KCS Notes have not been registered under the Securities Act, or any state securities laws, and may not be offered or sold in the United States absent registration or an applicable exemption from registration requirements, and will therefore be subject to substantial restrictions on transfer. KCS and the guarantors have entered into a registration rights agreement with respect to the KCS Notes and the note guarantees. This press release is for informational purposes only and is not an offer to purchase, a solicitation of an offer to purchase or a solicitation of consents with respect to, any securities.
