(1)	On June 19, 2017, the Issuer and certain of its subsidiaries (collectively, the "Debtors") filed voluntary petitions for relief under chapter 11 of title 11 of the United States Code in the United States Bankruptcy Court for the District of Delaware (the "Bankruptcy Court"). On August 2, 2017, the Bankruptcy Court entered an order confirming the Debtors' prepackaged joint plan of reorganization, dated as of July 25, 2017 (as amended and supplemented from time to time, the "Plan"), and on August 31, 2017 (the "Effective Date"), the Plan became effective pursuant to its terms and the Debtors emerged from bankruptcy.
(2)	On the Effective Date, all outstanding shares of the Issuer's common stock, par value $0.01 per share (the "Old Common Stock"), and all options to purchase such Old Common Stock and all unvested restricted stock units with respect to such Old Common Stock, were cancelled and extinguished. The Reporting Person owned 9,147 unvested restricted stock units and 202,605 unexercised stock options that were cancelled pursuant to the Plan.
(3)	Represents restricted stock granted by the Issuer pursuant to the A.M. Castle & Co. Management Incentive Plan. The restricted stock vests in full on August 31, 2020.
(4)	New shares of the Issuer's common stock, par value $0.01 (the "New Shares"), were issued to the Reporting Person pursuant to the Plan in exchange for Old Common Stock held by the Reporting Person on the Effective Date under the Plan. The Reporting Person received 0.1231 New Shares for every share of Old Common Stock held by the Reporting Person on the Effective Date. The receipt of New Shares was involuntary, without consideration and in accordance with the Plan approved by the Bankruptcy Court.
(5)	Represents New Shares held in the A.M. Castle & Co. 401(k) Plan.
