How much is Diane Hendricks Worth? Diane Hendricks Net Worth in 2026
Diane Hendricks’s net worth is estimated at $23.6 billion as of November 2026. Her company, ABC Supply, sells about $55 million of shingles, siding, windows and wallboard every day of the year, by our math, and has no outside shareholders to answer to. She started it in 1982 with her husband, Ken, and a loan, after a youth spent on a Wisconsin dairy farm and a job assembling pens at the Parker Pen factory in Janesville.

How much is Diane Hendricks worth in 2026?
About $23.6 billion, by our estimate. ABC Supply is private and publishes only its sales: $20.2 billion in 2025 from more than 900 branches, the National Roofing Contractors Association reported in June 2026. The best price tag for a business like it is the one QXO paid for Beacon Roofing Supply in 2025, and we use that deal to value ABC.
How we got to $23.6 billion
| Source | Our estimate | What it rests on |
|---|---|---|
| ABC Supply, through Hendricks Holding Company | $22.8 billion | QXO paid about $11 billion for Beacon, a price that covered Beacon’s debt as well as its shares. Beacon had 2024 sales of $9.76 billion, so the deal valued the whole business at about 1.13 times sales. Applied to ABC’s $20.2 billion, that is $22.8 billion. ABC publishes no debt figure, so we subtract none; every $1 billion it owes would cut this row by $1 billion. |
| Other investments and real estate | $800 million | Our assumption. The Hendricks began by renting out houses and industrial buildings, and their holding company invests in other private firms. No values are public. |
| Total | $23.6 billion | Rough estimate for a private company. |
We credit the whole company to her. She created Diane M. Hendricks Enterprises in 2008 as the parent of ABC Supply and the family’s other investments, and in 2025 it merged with Hendricks Holding Company and took that name, the holding company says. No other owner is named. She has seven children, and if any of them hold shares the figure overstates her own slice.
Twice Beacon, flat since 2022
Beacon was a listed roofing distributor until QXO bought it for $124.35 a share, a deal QXO said was worth about $11 billion when it closed on April 29, 2025. Beacon’s 2024 results showed $9.76 billion of sales and $930 million of adjusted EBITDA from more than 580 branches. ABC sells about 2.1 times as much.
The surprise is in ABC’s own history. The company’s timeline puts 2022 sales at $20.4 billion, and 2025 came in at $20.2 billion. Our calculation: after rising 69% from $12.1 billion in 2020 to $20.4 billion in 2022, sales have since slipped about 1%. A flat top line is one reason we do not pay a growth premium for the company.
A farm girl with a broker’s license
Diane Smith grew up in Osseo, Wisconsin, had her first child at 17 and earned a real estate broker’s license at 21, her biography notes. She married Ken Hendricks, a roofing contractor, in 1975. The couple rented out houses, moved into industrial property, and in 1982 borrowed to start American Builders and Contractors Supply in Beloit.
The chain grew by buying rivals. Its two largest deals were Bradco in 2010 and L&W Supply in 2016. L&W now trades as ABC Supply Interiors with more than 270 locations, part of a new naming structure that also created ABC Supply Outdoor Solutions. She ran the company as chairman after Ken’s death in 2007. The holding company says she stepped down as chairman of ABC Supply and the holding company in 2024 and is now listed as founder.
Much of her spending goes into Beloit itself. In 2025 she paid to restore historic houses in the town for the A&E series Betting on Beloit, which she made with her daughter Konya Hendricks Schuh.
Why other estimates disagree
Public estimates sit fairly close to ours, and the gaps come from two choices. One is the multiple: some lean on fast-growing listed distributors rather than the Beacon deal. The other is debt, which ABC does not publish: an estimate that takes off $4 billion of borrowing lands near $19.6 billion. With no shares traded, a swing of a few tenths in the sales multiple moves her figure by billions.
What would move the figure
A sale of ABC, a stake sale or a published debt figure would reset the number. Each 0.1 change in the sales multiple shifts it by about $2 billion. A recovery in roofing demand that lifts sales above the 2022 peak would support a higher multiple.
