The 152,932 phantom stock units that vested on March 13, 2026 were settled in cash at a value equal to the number of units vested multiplied by the closing price per share of common stock of Tutor Perini Corporation (Issuer) on the vesting date. The reporting person did not purchase or sell any shares of common stock in the settlement of this award, however, the transaction is required to be reported as an acquisition and disposition of shares back to the Issuer under SEC reporting principles.
