KKR & Co. finalized a $2.1 billion leveraged loan to fund its latest acquisition.

The debt supports the $5.7 billion purchase of medical-device manufacturer Integer Holdings Corp.

High investor demand enabled KKR to secure a lower interest rate spread.

The firm sold the debt at par, improving on initially discussed terms.

Citigroup led the financing for the all-cash deal announced in August 2026.

The transaction will take Integer private and is scheduled to close by the end of the year.

This move highlights a growing market appetite for acquisition-related leveraged loans.
