The three finalists include Omnicom Group's DDB, a roster shop that has Wrigley business in Australia and New Zealand and two non-roster agencies, Publicis Groupe's Saatchi & Saatchi and Interpublic Group's DraftFCB.
Omnicom's BBDO, along with Leo Burnett and Grey, failed to make the final cut. However, EnergyBBDO in Chicago remains Wrigley's lead agency in the US and BBDO is expected to remain on its roster.
The shortlist appears to severe the Chicago-based company's relationship with Grey, which has business in Asia and India, and Burnett, which represents Wrigley in Canada and parts of Asia.
All three finalists are now set to submit price proposals to procurement advisors. The review was called to allow Wrigley to consolidate global creative duties into two networks.
It was first announced in April, when Wrigley said the pitch process would be completed this summer.
Media planning and buying duties, handled by WPP's MindShare, are unaffected by the creative review. In the UK the account is handled by WPP's MediaCom.
Wrigley's Extra is the second biggest confectionery brand in the UK. Included in the Wrigley's gum umbrella are Airwaves, Orbit, Juicy Fruit, Wrigley's Spearmint, Doublemint and Hubba Bubba bubblegum.
The company was founded in 1891 and sells its brands in more than 180 countries.
