He and Jacqueline each own an estimated one-third of the company. His late brother Forrest Jr.'s four daughters are believed to own the rest. The $65 billion (sales) business was founded by John's grandfather, Frank, in 1911. Mars acquired snack company Kellavova in December 2025 for $35.9 billion including debt.
