CODI Provides Update on Refinancing and Strengthened Capital Structure

Reduces Weighted Average Cost of Debt, Extends Maturity Profile and Increases Liquidity

$569 Million of Revolver Available to Fund Future Acquisitions

WESTPORT, Conn. – March 23, 2021 – Compass Diversified (NYSE: CODI), an owner of leading middle market businesses, today provided an update on its recent refinancing and strengthened capital structure.

Following today’s closing of Compass Group Diversified Holdings LLC’s (the “Company” and, together with Compass Diversified, “CODI”) previously announced offering of $1.0 billion of 5.250% senior unsecured notes due 2029 (the “Notes”) in a private transaction and a concurrent refinancing transaction, CODI has repaid the debt under the Company’s previous credit facilities and, effective April 1, 2021, will redeem the Company’s 8.000% Senior Notes due 2026. In addition, CODI now has access to $569 million of its $600 million revolving credit facility available to fund future acquisitions.

“We are pleased to complete this refinancing and strengthen CODI’s capital structure to reduce our weighted average cost of debt, extend our maturity profile, and increase our liquidity,” said Elias Sabo, CEO of Compass Diversified. “Evaluating more efficient ways to tap into the capital markets remains a priority for our team. With access to capital at a lower cost, we believe we are better positioned to continue to leverage our permanent capital structure to our advantage as we seek to opportunistically acquire businesses and generate significant shareholder value.”
