The private equity firm Kohlberg Kravis Roberts & Company said on Wednesday that it had sold off its remaining stake in the British drugstore chain Alliance Boots.
The sale follows Monday’s vote by Walgreen & Company shareholders, who approved the acquisition of the 55 percent of Alliance Boots that Walgreen did not already own. The private equity’s firms shares were sold to the holding company that has now been formed, Walgreens Boots Alliance.
In 2007, Kohlberg Kravis, along with Stefano Pessina, who was Alliance Boots deputy chairman and its largest shareholder at the time, took the British company private in a $22 billion deal — Europe’s largest ever leveraged buyout. The private equity firm invested $1.8 billion in Alliance Boots.
