Renate Reimann-Haas Net Worth

Renate Reimann-Haas has an estimated net worth of $6.4 billion, according to Forbes Real-Time Billionaires, Renate Reimann-Haas profile (figures as of October 20, 2026). That is up from $3.7 billion in 2019.

Renate Reimann-Haas is a German-Austrian heiress and one of the owners of JAB Holding Company, a Luxembourg-based investment firm. She belongs to the Reimann family, whose business history goes back to chemist Ludwig Reimann, who joined Johann Adam Benckiser and his chemical company in 1828. Born on 8 October 1951, she became an Austrian citizen in 2006 and has lived outside Germany since then.

Before her wealth became widely known, she built a career in science. She earned a doctorate in chemistry and worked in the organic chemistry department of the Max Planck Institute for Medical Research in Heidelberg, publishing research in the journal Angewandte Chemie. She has kept a very low profile, giving almost no interviews, and once played clarinet in a local big band in Laudenbach.

Where the Reimann-Haas fortune comes from

Her wealth began with an inheritance. In 1984 she and eight other heirs each received 11.1% of the family business, Joh. A. Benckiser. That company later merged with the British firm Reckitt and Colman in 1999 to form Reckitt Benckiser. Over time, five of the heirs sold out, and Renate and three of her siblings now own 95% of JAB, the investment firm that manages the family's money.

JAB has built a large portfolio of consumer brands. Names linked to the Reimann fortune include Pret A Manger, Krispy Kreme, Peet's Coffee and Panera Bread. JAB also moved into pet care in 2019 when it bought Compassion-First Pet Hospitals. Because these holdings span coffee, food and animal health, her fortune depends on how JAB's mix of companies performs and how Forbes values them.

How her Forbes estimate has moved

Forbes estimated Reimann-Haas at $3.7 billion in 2019 and $4.7 billion in 2020, before a dip to $3.8 billion in 2021. Her figure then jumped to $5.8 billion in 2022. It held fairly steady at $5.4 billion in 2023 and $5.6 billion in 2024, then fell to $4.5 billion in 2025 as the value of JAB's holdings shifted.

The latest numbers show a strong rebound. On its 2026 World's Billionaires List, Forbes put her at $6.4 billion, and its real-time billionaires tracker showed the same $6.4 billion as of October 20, 2026. Alongside the business, she and her siblings founded the nonprofit Benckiser Stiftung Zukunft in 2005, which later became part of the Alfred Landecker Foundation in Berlin.
