On June 26, 2026, pursuant to the Merger Agreement, Merger Sub merged with and into ProAssurance (the “Merger”), the separate corporate existence of Merger Sub ceased, and ProAssurance was the surviving corporation in the Merger (the “Surviving Corporation”) and, as a result, is now a wholly owned subsidiary of The Doctors Company.

In addition, pursuant to the Merger Agreement, as of the Effective Time, (i) except as otherwise agreed to in writing between a holder of restricted stock units and The Doctors Company, each restricted stock unit payable in shares of ProAssurance Common Stock that was issued and outstanding immediately prior to the Effective Time (excluding any such restricted stock units that were forfeited at or prior to the Effective Time in accordance with their terms or in accordance with the Merger Agreement) became fully vested and converted into the right to receive an amount in cash (without interest, less any applicable withholding taxes payable in respect thereto) equal to the Merger Consideration, (ii) except as otherwise agreed to in writing between a holder of performance shares and The Doctors Company, each outstanding performance share payable in shares of ProAssurance Common Stock (determined based on deemed target level performance) automatically vested and converted into the right to receive an amount of cash (without interest, less any applicable withholding taxes payable in respect thereto) equal to the Merger Consideration and (iii) all amounts held in deferred compensation
