Following a year-long plunge in his company’s share price, the executive chair and biggest shareholder of Walgreens Boots Alliance Stefano Pessina has seen the market value of his holding in the company plummet. 

According to data from FactSet reported by The Times, Pessina’s holding has fallen from $4.4bn (£3.5bn) to $2.2bn (£1.7bn) in the past year after shares at Walgreens dropped 40% in the last 12 months, the same period in which the S&P 500 share index gained 9%.
