Richard Evans, president and CEO of PepsiCo UK and Ireland, said the group was currently seeking a replacement and would miss Johnston's experience, particularly in soft drinks.
"David's 13 years at PepsiCo have seen a great many achievements," said Evans. "He has driven strong performance across the portfolio and made a very substantial contribution to PepsiCo. David leaves an enduring legacy."
The MD of a rival soft drinks company expected Johnston's successor to come from within PepsiCo.
"Traditionally, PepsiCo promotes internal candidates to these positions," he said. "It's a tough role but likely to attract a lot of interest. Johnston did a good job, considering the circumstances."
Meanwhile, Rupert Duchesne, CEO of Groupe Aeroplan, described Johnston's appointment as "an important step" for the company. "With David's proven knowledge of the market, impressive international experience and well-honed leadership capabilities, we have added significant power to our talent base in Europe," he said.
