Dimensional Fund Advisors LP Reports 2.8% Stake in ProAssurance Corp (PRA)

Dimensional Fund Advisors LP filed a Schedule 13G/A on April 9, 2026, disclosing a position in ProAssurance Corp (PRA). As of the event date on March 31, 2026, the filer reported beneficial ownership of 1,442,782 shares of Common Stock, representing 2.8% of the class. This filing serves as an amendment to a previous report. Dimensional Fund Advisors LP, an investment adviser, maintains sole dispositive power over all 1,442,782 shares and sole voting power over 1,411,907 shares. The filing indicates that the securities are held in the ordinary course of business by various investment companies, trusts, and accounts for which Dimensional serves as an adviser or manager. Notably, the firm disclaims beneficial ownership of these securities. Since the ownership level is now below the 5% threshold (at 2.8%), this filing reflects a decrease in reported ownership percentage compared to previous thresholds, though it marks an initial disclosure of this specific 2.8% position in the current reporting cycle.
