They join the business during difficult times. Registered in Switzerland, listed in London but rooted in Greece, Coca-Cola HBC has been at the mercy of uncertainty caused by the financial crisis.
It switched its listing to London in 2013 hoping for better liquidity. Shares in the business have however, slumped heavily since September that year, though they have been on a generally upward trend since the beginning of 2015.
Revenues have suffered too. The year to December 2013 saw income of £5.7bn, while the last year they stood at £5.08bn. Pre-tax profits have, however, stood up rising from £246.2m in 2013 to £275m last year. Earnings per share improved from 51.08p to 63p.
