KCG ANNOUNCES FULL REPAYMENT
OF FIRST LIEN CREDIT FACILITY

KCG will save a minimum of $66.4 million in total interest expense
from early repayments of the loan

JERSEY CITY, N.J. - April 15, 2014 - KCG Holdings, Inc. (NYSE: KCG) today announced the completion of a $50 million principal repayment of the first lien term loan under the Company's first lien senior secured credit facility. With the repayment, KCG has fully repaid the $535 million loan entered into on July 1, 2013 and terminated the facility ahead of its December 5, 2017 maturity date.

Daniel Coleman, Chief Executive Officer of KCG, said, "We're pleased to have the ability to aggressively pay off the debt associated with financing the merger. In under a year since the close, we've substantially reached the target capital structure and dramatically lowered our future interest expense. Going forward, we have added flexibility in terms of utilizing cash generated from day-to-day activities."

The $50 million repayment was sourced from internally generated excess liquidity. As a result of the repayment, KCG will record a writeoff of $2 million in capitalized debt costs in the second quarter of 2014. In all, KCG will save a minimum of $66.4 million in total interest expense from the full early repayment of the loan compared to following the prescribed repayment schedule through the maturity date.

With the full repayment of the first lien term loan, KCG is free of the covenants contained in the loan, including an annual $15 million cap on share repurchases. KCG remains subject to a limitation on share repurchases based in part on operating results under covenants of the Company's second lien senior secured notes.
