On June 12, 2026, Chief Legal Officer Todd C. Girolamo of ProKidney Corp. effected an internal conversion of 163,857 paired securities—each consisting of one share of Class B Common Stock and one Common Unit in ProKidney Holdings, LLC—into 163,857 shares of Class A Common Stock on a one-for-one basis pursuant to the company’s exchange agreements and prior business combination structure. The transaction, coded as a change in form of beneficial ownership rather than an open‑market trade, left the insider with 327,713 shares of Class A Common Stock held directly, while eliminating his corresponding Class B and Common Unit positions; no transaction price or market value was disclosed in the filing and the move appears to be a structural simplification of his ownership rather than a discretionary purchase or sale.
