ProFrac Holding Corp.’s major shareholders led by the Wilks family and affiliated entities report updated beneficial ownership of 150,570,115 shares of Class A common stock, representing about 82.7% of the company’s outstanding Class A shares.

The filing shows holdings spread across THRC Holdings, FARJO entities, family trusts, Wilks Brothers LLC and a private foundation, with various parties disclaiming beneficial ownership of certain affiliate-held shares. Shares listed in Schedule I were acquired with working capital or personal funds in offerings undertaken by the company for general investment purposes.

Insights
Wilks-affiliated group reports controlling stake of over 80% in ProFrac.
The filing shows a coordinated group of Wilks family entities and affiliates beneficially owning 150,570,115 Class A ProFrac shares, or about 82.7% of the class. This reflects very concentrated ownership and effective control in the hands of a small, related group.
The calculation is tied to 180,920,753 Class A shares outstanding as of May 1, 2026, plus 1,071,454 shares issued to Wilks Brothers LLC on June 25, 2026. Some interests arise from Series A Redeemable Convertible Preferred Stock, adding a layer of structural complexity.
Because the group already reports control, this amendment primarily refreshes ownership data, entity roles, and disclaimers of beneficial ownership among related parties. Subsequent company filings may further detail any future changes in this highly concentrated ownership structure.

beneficial ownersfinancial
"In aggregate, the Reporting Persons are the beneficial owners of 150,570,115 shares of Class A Common Stock"
Beneficial owners are the people or entities that actually enjoy the economic benefits and control of shares or other assets, even when legal title is held by someone else such as a broker, custodian or trustee. Investors pay attention because beneficial owners hold the real voting power, receive dividends and can influence strategy and takeover outcomes — like the driver of a car who uses and maintains it while the bank holds the title — so disclosure shows who truly controls and benefits.
Schedule 13Dregulatory
"If the filing person has previously filed a statement on Schedule 13G to report the acquisition"
A Schedule 13D is a legal document that investors file with regulators when they buy a large enough stake in a company to potentially influence its management or decisions. It provides details about the investor’s intention, ownership stake, and plans, helping other investors understand who is gaining control and what their motives might be.

sole voting powerfinancial
"Number of Shares Beneficially Owned by Each Reporting Person With: 7 | Sole Voting Power 82,452,422.00"
Sole voting power is the exclusive right to cast votes attached to a shareholder’s stock without needing approval from anyone else. Like holding the only remote control for a TV, it lets that holder decide corporate matters such as board members, mergers, and policy changes, making it important to investors because it concentrates control and can strongly influence a company’s strategy and the value of its shares.
sole dispositive powerfinancial
"9 | Sole Dispositive Power 82,452,422.00"
Sole dispositive power is the exclusive legal authority to decide what happens to a security — for example, whether to sell, transfer, or retain shares — without needing anyone else’s permission. Investors care because it signals who truly controls the economic outcome of an investment: like holding the only key to a safe, the holder can realize gains or losses and may trigger regulatory reporting, insider rules, or influence over corporate ownership.
