COTT CORPORATION EXPECTS 2005 EARNINGS TO BE
SUBSTANTIALLY BELOW PREVIOUSLY ANNOUNCED GUIDANCE

TORONTO, September 21, 2005 — Cott Corporation (NYSE:COT; TSX:BCB) today announced that it expects its 2005 earnings to be substantially below previously announced guidance. Earnings are being impacted by continued carbonated soft drink volume softness in the U.S., product mix shift towards lower margin bottled water and escalating raw material costs.

“The entire soft drink industry is dealing with the impact of rising PET costs,” commented John Sheppard, President and Chief Executive Officer of Cott. “When we add this to the changes we are seeing in the market and our ongoing operational challenges, we expect a substantial impact on our full-year results.”

The Company withdrew its previous financial guidance and did not provide revised guidance for 2005 as it is currently reviewing a number of initiatives to cover cost increases and streamline operations while delivering improved customer service.

“Over the years, Cott has demonstrated its ability to change in order to deliver long term shareowner growth,” added Sheppard. “The management team is focused on taking quick and decisive action to address the current challenges.”
