[SCHEDULE 13D/A] PROKIDNEY CORP. Amended Major Shareholder Report
Control Empresarial and the Slim family have amended their Schedule 13D/A filing for ProKidney Corp., disclosing a beneficial ownership of 73,842,723 shares of Class A common stock, representing 36.0% of the outstanding shares. This increase in holdings is primarily due to an exchange on April 28, 2026, where Control Empresarial converted 63,118,645 Paired Interests and Class B common stock into Class A common stock. The updated ownership percentage is calculated based on a total of 205,061,550 Class A shares outstanding.
