BREAKING NEWS
Tensar CMC’s ‘BB+’ Ratings Affirmed as Leverage Increase According to S&P Global
CMC will use debt to fund the $1.84 billion purchase price of Foley Products after using cash proceeds for the $675 million CP&P acquisition in September 2025
Tensar’s Debt Position Increases
S&P Global affirmed Tensar’s Parent Commercial Metals Company (CMC)’s long-term issuer credit rating at ‘BB+’ (speculative-grade, one notch below investment grade). The outlook likely remains stable, but the agency notes higher leverage following two large acquisitions:
- $675 million for CP&P in September 2025, funded largely from cash
- $1.84 billion for Foley Products, to be funded primarily through new debt
Affirmation at BB+ means S&P believes CMC will maintain sufficient cash flow and operating performance to stay within its current credit category, even with higher debt levels.
Tensar’s Strong Performance Leads to Surge in CMC’s Profitability
CMC reports improved segment profitability on a year-over-year basis was driven by record Tensar performance that benefited from solid demand and enhanced cost efficiency
Chinese Researchers Develop Breakthough Enhanced HDPE Geomembranes
In this new HDPE GMB nanoclay is evenly dispersed in the HDPE substrate through a melt blending process to form a three-dimensional nano-barrier structure, which greatly reduces the water vapor permeability, and the barrier efficiency is increased by more than 80% compared with traditional geomembranes
