On October 9, 2019 (the “Closing Date”), VFH Parent LLC (“VFH Parent”), a Delaware limited liability company and indirect subsidiary of Virtu Financial, Inc., a Delaware corporation (the “Company”), entered into Amendment No. 1 (“Amendment No. 1”), which amended the Credit Agreement dated as of March 1, 2019 (the “Existing Credit Agreement” and as amended by Amendment No. 1, the “Amended Credit Agreement”) by and among VFH Parent, Virtu Financial LLC, a Delaware limited liability company, direct subsidiary of the Company and the parent company of VFH Parent, the lenders party thereto, and Jefferies Finance, LLC (“Jefferies”), as administrative agent and collateral agent (in such capacities, the “Agent”), to, among other things, provide for $525.0 million in aggregate principal amount of incremental term loans (the “Incremental Term Loans”), and amend the related collateral agreement.

On the Closing Date, VFH Parent borrowed the Incremental Term Loans and used the proceeds together with available cash to redeem all of the $500.0 million aggregate principal amount of the outstanding 6.750% Senior Secured Second Lien Notes due 2022 (the “Existing Notes”) issued by VFH Parent and Orchestra Co-Issuer, Inc., a Delaware corporation and indirect subsidiary of the Company (together with VFH Parent, the “Issuers”), and pay related fees and expenses.

The terms, conditions and covenants applicable to the Incremental Term Loans are the same as the terms, conditions and covenants applicable to the existing term loans under the Existing Credit Agreement, including a maturity date of March 1, 2026. The Company previously entered into a five-year $525 million floating to fixed interest rate swap agreement that effectively fixes interest payment obligations on the Incremental Term Loans at 4.8% through September 2024.

The above description of Amendment No. 1 does not purport to be complete and is subject to, and qualified in its entirety by reference to the full text of Amendment No. 1, a copy of which will be filed as an exhibit to the Company’s next quarterly report on Form 10-Q.
