Nucor Corp. has acquired C.H.I. Overhead Doors, a garage door services provider, from investment firm KKR for $3.0 billion.

The sale represents one of KKR’s largest returns in recent history, with KKR earning 10x the equity invested.

“We can’t thank our strategic partners at KKR enough for believing in us at C.H.I., providing a life-changing experience for us all and driving a movement not only across the industry, but across the country,” said C.H.I. CEO Dave Bangert. “Looking ahead, we’re excited to come together with Nucor who shares our cultural values and wants to keep building with us.”

KKR and C.H.I. were advised by Goldman Sachs as financial and M&A advisor, UBS as M&A co-advisor, and Kirkland and Ellis as legal advisor on the transaction.
