Ecovyst Inc. (NYSE: ECVT) announced plans to issue a $100 million fungible Term Loan B add-on to finance its pending acquisition of the Calabrian sulfur dioxide and related sulfur derivatives business from INEOS Enterprises.

The acquisition is targeted to close by the end of the second quarter 2026, according to the company's statement. The add-on will be used alongside cash on the balance sheet to fund the transaction.

The new term loan is expected to be co-terminus with Ecovyst's existing $397 million Term Loan B, which is due in June 2031.

"We believe this amendment to our Term Loan Facility, along with cash on hand, will provide the optimal financing structure for the Calabrian acquisition, expected to close at the end of the second quarter," said Mike Feehan, Ecovyst's Chief Financial Officer.

Feehan stated that the company expects its combined net debt leverage ratio to be approximately 2x at the close of the transaction.

Ecovyst operates as a provider of 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.
