Explanation of Responses:

*	If the form is filed by more than one reporting person, see Instruction 4(b)(v).
**	Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1)	The Reporting Person received 12,488 shares of the Issuer's common stock in exchange for 7,301 shares of common stock, without par value, of Olympic Steel, Inc. ("Olympic Steel") in connection with the merger between Olympic Steel and the Issuer (the "Merger") pursuant to the terms of the Agreement and Plan of Merger, dated as of October 28, 2025 (the "Merger Agreement"), by and among the Issuer, Olympic Steel and Crimson MS Corp. In accordance with the Merger Agreement, each share of Olympic Steel's common stock was cancelled and converted into the right to receive 1.7105 shares (the "Exchange Ratio") of the Issuer's common stock, with cash paid in lieu of fractional shares.
(2)	The Reporting Person received 5,011 shares of the Issuer's common stock in exchange for restricted stock awards with respect to 2,930 shares of Olympic Steel's common stock, in connection with the Merger pursuant to the terms of the Merger Agreement. Pursuant to the Merger Agreement, at the effective time, the reporting person's Olympic Steel restricted stock awards vested and converted into shares of the Issuer's common stock (rounded down to the nearest whole share) determined by multiplying (i) the number of shares of Olympic Steel common stock subject to the Olympic Steel restricted stock award prior to the effective time of the Merger by (ii) the Exchange Ratio.
(3)	Each restricted stock unit represents a contingent right to receive one share of common stock of the Issuer.
(4)	The restricted stock units have fully vested. Vested shares will be delivered to the reporting person upon separation of service.
(5)	Pursuant to the Merger Agreement, at the effective time, the reporting person's Olympic Steel restricted stock units were assumed and converted into restricted stock units with respect to a number of shares of the Issuer's common stock (rounded down to the nearest whole share) determined by multiplying (i) the number of shares of Olympic Steel common stock subject to the Olympic Steel restricted stock unit immediately prior to the effective time of the Merger by (ii) the Exchange Ratio. The converted restricted stock units will otherwise be subject to the same terms and conditions as were applicable to the Olympic Steel restricted stock units prior to the effective time of the Merger.
(6)	The Reporting Person received 5,873 restricted stock units of the Issuer in exchange for restricted stock units with respect to 3,434 shares of Olympic Steel's common stock.
(7)	The Reporting Person received 4,435 restricted stock units of the Issuer in exchange for restricted stock units with respect to 2,593 shares of Olympic Steel's common stock.
