Nutri-Grain is a cereal bar brand launched in 1981, sold as a breakfast on the move with a soft fruit filling. It has been positioned differently by market: a cereal in Australia, a bar in Britain and the United States, which is unusual for a brand of its size.
Mars is a family-owned company headquartered in McLean, Virginia, United States, founded in 1911. Brandtree records 42 brands under its control.
Mars is one of the largest privately held companies in the world, owned by the Mars family since Frank Mars began making sweets in Tacoma in 1911. It publishes no financial statements. Its four segments are snacking, pet nutrition, food and Mars Wrigley, and it agreed to acquire Kellanova in 2024.
Brandtree records a controlling owner for 2,549 brands that began in the United States.
478 of them (19%) are now controlled by a company headquartered in another country; Nutri-Grain is not one of them.
Mars agreed in August 2024 to buy Kellanova for $83.50 a share in cash, a total enterprise value of $35.9 billion including assumed net leverage, and completed the purchase on 11 December 2025 after the last regulatory approvals arrived three days earlier. Kellanova became a wholly owned subsidiary of Mars and its shares left the New York Stock Exchange. The brands did not change hands individually: Pringles, Cheez-It, Pop-Tarts, RXBAR and the international Kellogg cereals stay with Kellanova, which is now a private family-owned company's snacking arm rather than a listed business.
The parent company of Nutri-Grain is Mars, a family-owned company headquartered in the United States. Nutri-Grain sits under Mars' subsidiary Kellanova.
