The deputy chairman of Fever-Tree (LON: FEVR) is celebrating a £82.5 million payday after selling a stake in the group.

Charles Rolls, a co-founder of the mixer maker, cashed in the group’s recent success and offloaded a 2.6 percent stake.

Since the group’s stock market flotation in late 2014, share prices of the beverage company have increased over 1000 percent. In the past 12 months alone, the share price has jumped 90 percent.

Chief executive, Tim Warillow, said the company has had an “encouraging start to 2018 and remain confident that we are increasingly well positioned to deliver further growth across the business”.

Rolls sold a total of three million shares, each priced 2,750 pence. He still owns an 8.6 percent stake in the group.

This is not the first time Rolls has made a significant sum from cashing in shares. Last year, the co-founder and deputy chairman cashed in £73 million worth of shares.

Fever-Tree has rapidly expanded its international sales and makes the bulk of annual revenues in the US, Spain and Belgium.

Rolls began his journey into tonic water when he noticed that the world’s finest gins were mixed with mass-produced mixers.

The company offers a premium tonic water with no artificial sweeteners, preservatives or flavourings.

“There’s no point having a good gin if the tonic isn’t right,” he said.

The group now sells 12 different mixers.

Shares dropped 5.4 percent to 2,796 pence in morning trading.
