Ecovyst Inc. (NYSE: ECVT) completed syndication of a $100 million Term Loan B add-on to finance part of its pending acquisition of the Calabrian sulfur dioxide and sulfur derivatives business from INEOS Enterprises, according to a company statement.

The add-on was issued at par and carries the same terms as Ecovyst's existing $397 million Term Loan B, which matures in June 2031. The loan carries a floating interest rate of SOFR plus 2.00 percent per annum.

Both the acquisition and the loan add-on are expected to close by the end of the second quarter of 2026, the company said.

Ecovyst provides virgin sulfuric acid and regenerated sulfuric acid products and services. The company serves the North American refining industry with sulfuric acid recycling for alkylate production and produces virgin sulfuric acid for industrial and mining applications. It also offers chemical waste handling and treatment services.
