Quaker Oats is reviewing its advertising account, putting incumbent Abbott Mead Vickers BBDO on alert.
Pitches are due to take place in November and the PepsiCo porridge brand aims to make a decision by the end of that month. White Door Consulting is assisting with the review process.
AMV BBDO will defend the business against Havas London, Uncommon Creative Studio and Wonderhood Studios.
The agency picked up Quaker Oats in 2003 from Rainey Kelly Campbell Roalfe/Y&R (now known as VMLY&R), following PepsiCo's decision to consolidate its business into Omnicom Group agencies. The account was estimated to be worth £7.2m at the time.
This is the third time PepsiCo has reviewed an account previously held by AMV BBDO this year.
Earlier this month, Doritos appointed Mother to create a 2021 campaign for the western European market. AMV formerly worked on Doritos, though the brand has used other smaller agencies in recent years.
In July, VCCP won the Walkers and Sensations brands, the former of which AMV had worked on for 22 years.
AMV continues to work on Pepsi; the agency created a spot for the cola brand earlier this year featuring footballers Lionel Messi, Mo Salah, Paul Pogba and Raheem Sterling .
A PepsiCo spokesman said: “In-line with best practice, the creative account for the Quaker account is currently subject to a review.”
AMV BBDO declined to comment.
