ProFrac Holding Corp. Schedule 13D/A (Amendment No. 10) reports that a group of related persons and entities controlled by members of the Wilks family together beneficially own 151,864,809 shares of Class A common stock, representing approximately 88.66% of the outstanding Class A shares. The calculation cites 160,280,185 shares outstanding as of June 30, 2025, and includes convertible preferred stock convertible into 2,872,950 Class A shares and 42,744 shares issuable upon exercise of warrants.
The filing amends prior Schedule 13D filings and identifies reporting persons (THRC Holdings, THRC Management, FARJO Holdings, FARJO Management, Dan H. Wilks, Farris Wilks, Jo Ann Wilks, Matthew D. Wilks, the Farris and Jo Ann Wilks 2022 Family Trust and Heavenly Father’s Foundation). Purchases shown on Schedule I were funded by working capital for THRC Holdings and personal funds for Farris Wilks, and the stated purpose for the acquisitions is general investment. The filing states no contracts or arrangements regarding the issuer’s securities and indicates no transactions by the reporting persons in the last 60 days except as set forth on Schedule I.
Positive
Clear, detailed ownership disclosure quantifying aggregate holdings (151,864,809 shares) and basis for calculation
Identification of reporting persons and relationships (entities, trusts, trusteeship) reduces ambiguity about control
Funding sources stated for recent purchases (working capital for THRC Holdings; personal funds for Farris Wilks)
Purpose of acquisitions stated as general investment, with no undisclosed arrangements reported
Negative
Extremely concentrated ownership: Reporting group holds approximately 88.66% of Class A shares, materially limiting public float and liquidity
Potential dilution from convertible preferred shares (2,872,950 shares) and warrants (42,744 shares) included in ownership calculations
High control raises governance risk for minority shareholders because the group can effectively determine corporate actions
Insights
TL;DR The Wilks-related group controls a dominant 88.66% stake, significantly concentrating economic and voting power.
This Schedule 13D/A discloses an aggregate beneficial ownership of 151,864,809 Class A shares based on 160,280,185 shares outstanding, plus convertible preferred and warrants. From an investor-impact perspective, this level of concentrated ownership can materially limit free float and influence liquidity and market pricing. The inclusion of convertible preferred shares and warrants increases potential future dilution for other public holders, though the filing quantifies those instruments. The stated purchase funding sources (working capital for THRC Holdings; personal funds for Farris Wilks) and the designation of purchases for general investment are clear and reduce ambiguity about immediate takeover intent. Overall, the disclosure is granular and permits investors to quantify concentration risk and potential dilution.
TL;DR Reporting persons effectively control the company, raising governance and minority-holder considerations.
The filing shows related persons and affiliated entities jointly holding a near-control position at 88.66% of Class A shares, with individual holdings and trustee relationships disclosed. Such dominance gives these parties practical control over corporate decisions, board composition, and corporate strategy. The filing also provides disclaimers about cross-beneficial ownership among reporting persons, and identifies trustee roles (e.g., Dan and Staci Wilks as trustees of the Foundation), which clarifies fiduciary relationships. No contractual arrangements or pending legal proceedings are reported. For governance assessments, this concentration is material: minority shareholders may have limited influence, and conflicts of interest or related-party transactions warrant monitoring through future disclosures.
