On 19 May 2009, Viterra announced it would buy Australian ABB Grain for C$1.4 billion. On 9 September, 84 percent of ABB shareholders voted in favour of the merger, with 75 percent required to pass the resolution.
On March 15, 2012, Viterra announced that it had received takeover offers from multiple parties. Glencore was revealed to have offered a takeover bid of $6.1 billion. It intended to immediately sell off its Canadian assets to Agrium and Richardson International while retaining Viterra's overseas assets. The takeover deal was completed in December 2012.
Following Glencore's takeover of Viterra in December 2012, Viterra underwent some major changes. Viterra Inc. (Viterra) was acquired by a Glencore purchaser, 8115222 Canada Inc. and merged under the Canada Business Corporations Act (CBCA). The new board of directors includes Mr. Chris Mahoney (Director of Agricultural Products of Glencore), Mr. Ernest Mostert (Financial Manager of Glencore Grain), Mr. Robert Wardell and Mr. Larry Ruud (President & CEO One Earth Farms Corp).
In preparation for Glencore's acquisition of Viterra in December 2012, in March 2012, Agrium Inc entered into a $1.15bn sale agreement with Glencore, who in this way divested "90 percent of Viterra’s Canadian retail facilities, all of its Australian retail facilities, as well as their minority position in a nitrogen facility located in Medicine Hat, Alberta."

In 2016, Glencore sold a minority stake in the business to the Canada Pension Plan, who paid "US$2.5 billion for a 40 percent stake" in its global agricultural assets, by then renamed "Glencore Agriculture".
In 2020, Glencore Agriculture rebranded to Viterra and created a new brand identity, building off the Viterra brand that was created in 2007. In 2022, Gavilon was purchased by Viterra for $1.1 billion; it is expected Gavilon will be fully integrated in Viterra by early 2023.
In 2023, a merger with Bunge Limited was announced, though the merger was only approved by the Government of Canada in January 2025. In July 2025, Bunge announced that it had completed its $34 billion merger with Viterra.
