When you say that KKR did not sell off its entire holding you are again directly contradicting official filings made by the company - for which they would be liable if found to be incorrect.
On August 2, 2021, the Company entered into a stock purchase agreement to purchase 11,073,245 shares of its Common Stock and 1,000,000 shares of its Preferred Stock from affiliates of KKR for total consideration of approximately $396 million or $33.25 per share, on an as converted basis. After giving effect to the transaction, KKR no longer held any equity interests in the Company.
