Medellin, Colombia, January 8, 2020

Today, Bancolombia S.A. announced that Citigroup Global Markets Inc. has commenced an offer to purchase (the “Offer”) for cash any and all of the Issuer’s outstanding 5.950% Senior Notes due 2021 (the “Notes”) upon the terms and subject to the conditions set forth in an Offer to Purchase dated the date hereof (as it may be amended or supplemented from time to time, the “Offer to Purchase”). The Issuer intends to redeem all or a portion of the Notes that remain outstanding following the completion of the Offer.

The Offer to Purchase does not constitute a notice of redemption and no redemption will be binding on the Issuer until such time as a notice of redemption is delivered in accordance with the indenture dated as of June 3, 2011, among the Issuer and The Bank of New York Mellon, as trustee.

Citigroup Global Markets Inc. and J.P. Morgan Securities LLC are the dealer managers for the Offer. Global Bondholder Services Corporation has been appointed as the information and tender agent for the Offer.
