Walgreens Boots Alliance (Nasdaq: WBA) is reaching out to potential buyers of the £7 billion (about $8.8 billion) Boots drugstore chain in the U.K., according to Bloomberg News.

The company last year revived discussions on a potential exit from the U.K. chain, almost 18 months after scrapping a planned sale, Bloomberg reported. Boots could be valued at about $8.8 billion in an exit, with one possibility being an initial public offering in London, Bloomberg reported at the time. A sale would undo a blockbuster trans-Atlantic merger that took place in stages beginning more than a decade ago.
