Billy Rosenthal Net Worth 2026: Standard Meat and Penrose

Billy Rosenthal is the Fort Worth, Texas, businessman who ran his family's Standard Meat Company for decades and founded Penrose Group, the family's investment office, in 1998. No reputable outlet has published an estimate of his net worth. The figure of $500,000 that appeared on this page before was not only unsourced but clearly wrong: in January 2024 Rosenthal and his wife, Rozanne, gave $25 million to the University of Texas at Austin's McCombs School of Business, according to the university.

What is Billy Rosenthal's net worth?

There is no Forbes, Bloomberg or Texas business press figure for Rosenthal. His wealth is held through private family companies, chiefly Standard Meat and Penrose, whose values are not published. What the record does show is philanthropy on a scale that only a substantial fortune supports:

• $25 million to Texas McCombs in 2024, the first gift to name an academic department at the school, now the Rozanne and Billy Rosenthal Department of Management.
• $5 million pledged in May 2025 by Billy and Rozanne Rosenthal together with their children and their spouses toward a new Meat Science and Technology Center at Texas A&M, according to AgriLife Today.

Those gifts show the family's capacity to give, not his total wealth, so this page does not turn them into a net worth estimate.

Income and salary

His pay has never been published. The earlier version of this page claimed a yearly income of $60,000, with monthly and daily breakdowns. Nothing supports it, and it has been removed. His income comes from ownership of Standard Meat and from Penrose's investments.

Standard Meat Company

His grandfather, Ben H. Rosenthal, founded Standard Meat in Fort Worth in 1935, renting a meat locker, buying beef at the Stockyards and selling it door to door, the Fort Worth Report wrote. His father, Manny Rosenthal, studied at Texas A&M, took over as president in 1959, and pulled the company back from the brink of bankruptcy in the 1960s, Family Business Magazine reported.

Billy started as an 11-year-old delivery boy in 1961 and became president of Standard Meat at 31, according to Penrose's company history. When the company was sold to Sara Lee in 1983 he stayed on as president for six more years, then left in 1989 to start Rosani Foods, which made pepperoni for Pizza Hut. The family later brought Standard Meat back into its ownership. Customers over the years have included Outback Steakhouse, Pizza Hut, Taco Bell, Panera Bread and Brinker International.

In 2019 he handed day-to-day leadership to his son, Ben Rosenthal, and daughter, Ashli Rosenthal Blumenfeld, who run it as co-presidents. Under them, sales nearly doubled between January 2019 and 2025, Family Business Magazine reported, as the company moved from raw meat into ready-to-eat products. During the pandemic it also became a fulfillment center for meal kit company HelloFresh, Rosenthal told the Fort Worth Report.

Standard Meat timeline

The new plant is a 182,000-square-foot rebuilt historic processing building on the north edge of the Stockyards, with a sous vide line for ready-to-eat products, Meat+Poultry reported in April 2026. It joins Standard Meat plants in Dallas, Irving, Saginaw and Ponder, Texas.

Penrose Group

Rosenthal formed Penrose in 1998 to manage family trusts and investments, Family Business Magazine reported. The firm says it invests in food, sports and entertainment, health care, technology, finance and real estate, and lists him as founder and chairman.

Early life and education

Penrose's history says he was born in 1950, into the fourth generation of a family that came to the United States from Russia in the 1860s. He earned a BBA from the University of Texas at Austin in 1972, according to the university. The previous page's claim of a master's degree could not be verified and has been removed.

Wife and family

He is married to Rozanne Rosenthal, a 1974 UT Austin graduate and the founder of the Greater Fort Worth affiliate of Susan G. Komen, according to the Fort Worth Report. The earlier version of this page named his wife as "Miriam," which was wrong. Their children are Ben Rosenthal and Ashli Rosenthal Blumenfeld. The couple were named 2024 Fort Worth Business Executives of the Year by the Fort Worth Chamber of Commerce, Texas Wesleyan University and the Fort Worth Report.

Net worth compared

Rosenthal's story is close to that of other multigenerational meat companies on this site, such as Carl Buddig, the Chicago lunch meat business still owned by its founder's descendants. For another family business owner, see Bill Cameron of American Fidelity. The earlier version of this page linked to Cathleen Trigg Jones.

Why no figure is given

Standard Meat and Penrose are private, and neither the company's revenue nor the family office's holdings are disclosed. Recorded gifts of $25 million and $5 million prove the family is wealthy but do not measure its net worth. Until a reputable outlet publishes an estimate, the honest answer is that his net worth is unknown, and far above the figure previously shown here.
