US owner of UK pharmacy chain Boots, Walgreens Boots Alliance, is set to be taken private in a $10bn deal with US private equity firm Sycamore Partners.
Walgreens' market capitalisation has plummeted by 90% since 2015 and is now valued at $9.3bn, with debt and lease obligations of $30bn.
The deal will bring an end to Walgreens' 98-year run as a listed company, as it struggled in the internet era and faced competition from online shopping.
The sale also raises uncertainty for Boots' 50,000 employees, as plans to sell or spin off the UK pharmacy chain are expected.
