Item 1.01 Entry Into a Material Definitive Agreement.

On March 2, 2017 (the “Amendment Effective Date”), SS&C Technologies Holdings, Inc. (the “Company”) and certain of its subsidiaries entered into an amendment (the “Amendment”) to its senior secured credit agreement dated July 8, 2015 (the “Credit Agreement”) by and among the Company, SS&C Technologies, Inc., SS&C European Holdings S.a R.L, SS&C Technologies Holdings Europe S.a R.L., and certain of the Company’s subsidiaries, Deutsche Bank AG New York Branch, as administrative agent and collateral agent, and certain lenders and L/C issuers party thereto. The Credit Agreement, as amended, consists, in part, of a $91.9 million senior secured term loan A-1 facility maturing in July 2020 for borrowings by the Company’s wholly-owned subsidiary, SS&C European Holdings S.a.R.L (“Term Loan A-1”), a $142.5 million senior secured term loan A-2 facility maturing in July 2020 for borrowings by the Company’s wholly-owned subsidiary, SS&C Technologies Holdings Europe S.a.R.L. (“Term Loan A-2” and, together with Term Loan A-1, “Term Loan A”), a $1,480.2 million senior secured term loan B-1 facility maturing in July 2022 for borrowings by SS&C Technologies Inc. (“Term Loan B-1”), and a $142.1 million senior secured term loan B -2 facility maturing in July 2022 for borrowings by SS&C Technologies Holdings Europe S.a.R.L (“Term Loan B-2” and, together with Term Loan B-1, “Term Loan B”).

Pursuant to the Amendment, the highest (non-default) interest rate margin applicable to Term Loan A was reduced from LIBOR plus 2.75% to LIBOR plus 1.75%, and the highest (non-default) interest rate margin applicable to Term Loan B was reduced from LIBOR plus 3.25% to LIBOR plus 2.25%. The LIBOR “floor” for the Term Loan A and the Term Loan B is 0%. Subject to certain exceptions, in the event the Company and/or its subsidiaries enters into a transaction within six months from the Amendment Effective Date, the effect of which is to lower the “effective yield” of all or a portion of either the Term Loan A or the Term Loan B, the Company will pay to the applicable lenders a 1% prepayment premium on the loans subject to such transaction.

The foregoing description of the Amendment is qualified in its entirety by reference to the Amendment, a copy of which is filed as Exhibit 10.1 hereto and is incorporated herein by reference.

Item 8.01 Other Events.

On March 2, 2017, the Company issued a press release announcing that it had entered into the Amendment, a copy of which is filed as Exhibit 99.1 hereto and is incorporated herein by reference.
