Jean-Michel Besnier Net Worth

Jean-Michel Besnier has an estimated net worth of $8.5 billion, according to Forbes Real-Time Billionaires, Jean-Michel Besnier profile (figures as of October 20, 2026). That is up from $5 billion in 2019.

Jean-Michel Besnier is a French dairy heir who owns an estimated 21% of Lactalis, the biggest dairy producer in Europe. He was born around 1968 and lives in Laval, in the Mayenne area of western France, the family's ancestral hometown where Lactalis is still based.

He comes from three generations of the family business. His grandfather, André Besnier, founded the company that became Lactalis in 1933. His father, Michel Besnier, ran it as CEO from 1955 to 2000 and built it into a major group. Jean-Michel inherited the company together with his brother Emmanuel and his sister Marie.

Unlike his older brother, Jean-Michel keeps a low profile and is not the public face of the business. Emmanuel runs Lactalis as CEO and majority shareholder, while Jean-Michel's wealth comes from his minority stake in the family company.

How Jean-Michel Besnier made his money

Besnier's fortune comes entirely from Lactalis. The company sells $30 billion of products a year, including President brie, Milkmaid yogurts and Valbreso feta. It grew from a small dairy business in Laval into a global group by buying cheese, milk and yogurt brands across many countries.

Lactalis keeps expanding internationally, with growth in places such as China and Southeast Asia. Because it remains privately owned by the Besnier family, it does not publish a share price. Forbes estimates his stake based on the size and profits of the business, so his wealth tracks the long-term growth of the dairy empire his grandfather started.

The Besnier family is one of the wealthiest in France, and all three siblings appear on Forbes' rankings because of their shares in the dairy group. Jean-Michel's stake is smaller than his brother's, but it still places him among the richest people in the country.

How Forbes has valued Jean-Michel Besnier

Forbes valued Besnier at $5 billion in 2019 and $4.4 billion in 2020. His figure then climbed to $6.7 billion in 2021 and $8.2 billion in 2022. After a dip to $7.7 billion in 2023, it rose to $8.9 billion in 2024 and held near that level at $8.6 billion in 2025.

On the 2026 World's Billionaires List Forbes put him at $9.9 billion, his highest figure so far. As of October 20, 2026, the Forbes real-time billionaires tracker showed $8.5 billion. The steady climb reflects the growth of Lactalis as it adds brands and markets around the world.
