(the "Company"), Ryerson Holding Corporation ("Parent"), and Crimson MS Corp. At the effective time of the merger, each share of the Company's common stock, without par value ("Company common stock"), that was issued and outstanding immediately prior to the effective time of the merger was converted into the right to receive a number of shares of common stock, $0.01 par value per share, of Parent ("Parent common stock"), multiplied by 1.7105 (rounded down to the nearest whole share), plus a cash payment (rounded down to the nearest cent) in lieu of any fractional shares as determined pursuant to the Merger Agreement.

(2) Each restricted share unit ("RSU") represents the contingent right to receive one share of Company common stock.

(3) These RSUs are fully vested and will generally be settled upon the Reporting Person's separation from service. Pursuant to the Merger Agreement, these RSUs were converted into RSUs with respect to Parent common stock by multiplying the number of shares of Company common stock underlying the award by 1.7105 (rounded down to the nearest whole share).

(4) These RSUs generally vest on December 31, 2026, subject to the Reporting Person's continued employment and will be settled within 90 days following the applicable vesting date.
