Certara Inc. has announced that its indirect subsidiary, Certara USA, Inc., along with other wholly-owned subsidiaries, has entered into a Sixth Amendment to its existing credit agreement, originally dated August 15, 2017. The amendment, executed on October 16, 2025, introduces a reduction in the applicable interest rate for term loans under the agreement, a move expected to lower the company's borrowing costs and generate interest expense savings. The revamped terms were implemented through the establishment of Replacement Term Loans, which bear interest at either a Term SOFR rate plus a 2.75% margin or an Alternate Base Rate plus a 1.75% margin. The Replacement Term Loans were fully funded on the closing date and used to refinance the company's previous outstanding term loans. Other terms regarding guarantees, collateral, prepayments, and covenants remain substantially similar to the prior arrangement. Bank of America, N.A. continues as the administrative and collateral agent for the lenders.
