Koppers reprices $495 million term loan, cutting interest margin by 50 basis points

Positive financing Written later 1.012.03

Koppers Inc., a subsidiary of Koppers Holdings Inc. (NYSE: KOP), signed Amendment No. 5 to its credit agreement on December 17, 2024, lowering the interest rate margins on its senior secured Term Loan B.

  • Alternate base rate loans move from 2.00% (1.50% floor) to 1.50%, equal to the floor

Koppers to end phthalic anhydride production at Stickney plant in 2025

Mixed restructuring Written later 2.05

On December 5, 2024, subsidiary Koppers Inc. decided to discontinue phthalic anhydride production at its Stickney, Illinois facility, affecting approximately 25 employees, with a shutdown targeted for mid-2025. The company expects pre-tax charges of $51 million to $55 million through the end of 2026, which will reduce earnings, while the Stickney coal tar distillation operations continue and the company says the action lowers capital spending needs and emissions.

  • Phthalic anhydride production at Stickney, Illinois to be discontinued; shutdown targeted for mid-2025 with production ramped down over the next six months.
  • Approximately 25 employees affected; retention and severance costs estimated at about $1 million.
  • Pre-tax charges of $51 million to $55 million through end of 2026, including about $28 million non-cash and $23 million to $27 million cash.
  • Coal tar distillation at Stickney is not affected; 2025 goals of $300 million adjusted EBITDA and $65 million to $75 million capital expenditures incorporate the savings.
