[8-K] Ryerson Holding Corp Reports Material Event

Rhea-AI Filing Summary

Ryerson Holding Corporation announced a definitive agreement to acquire Olympic Steel in an all‑stock merger. Each share of Olympic common stock will be converted into the right to receive 1.7105 shares of Ryerson common stock, rounded down to the nearest whole share, with cash paid in lieu of fractional shares.

Closing is conditioned on Olympic shareholder approval, Ryerson stockholder approval for the share issuance, the effectiveness of a Form S‑4, NYSE listing approval for the new Ryerson shares, HSR Act clearance, absence of legal prohibitions, and other customary conditions. The merger agreement includes reciprocal $15 million termination fees tied to recommendation changes and up to $10 million expense reimbursement if stockholder approvals are not obtained.

Post‑closing, Ryerson’s board will expand to 11 directors, adding four Olympic designees. Michael Siegal will become Board Chair; Stephen Larson will resign at closing. Executive appointments include Richard Marabito as President and COO of Ryerson, with a $3,880,000 RSU sign‑on award vesting on the third anniversary of closing. Olympic equity and cash awards will be assumed, vested, or cash‑settled as specified.

M&A and Capital Markets Analyst

Stock-for-stock merger at a 1.7105 exchange ratio with customary approvals and reciprocal $15M break fees.

Ryerson agreed to merge with Olympic Steel via a stock swap: each Olympic share receives 1.7105 Ryerson shares. This structure avoids upfront cash outlay and ties value to Ryerson’s share price at closing, while fractional shares are settled in cash. The deal requires shareholder approvals at both companies, an effective Form S‑4, HSR clearance, and NYSE listing approval for the new shares.

Governance will shift with the board expanding to 11 and four Olympic designees joining, plus leadership appointments, including Michael Siegal as Chair and Richard Marabito as President and COO. Compensation elements include a $3,880,000 RSU grant to Marabito vesting three years post‑closing, and detailed treatment of Olympic RSUs/PSUs and cash awards.

Key safeguards include reciprocal $15,000,000 termination fees tied to recommendation changes and up to $10,000,000 expense reimbursement if stockholder approvals fail. The outside date is April 28, 2026, extendable to July 28, 2026 for regulatory approvals. Actual impact depends on satisfying conditions and integration outcomes.

Item 1.01 Entry into a Material Definitive Agreement.

On October 28, 2025, Ryerson Holding Corporation, a Delaware corporation (“Ryerson”), entered into an Agreement and Plan of Merger (the “Merger Agreement”), by and among Ryerson, Crimson MS Corp., an Ohio corporation and a direct wholly owned subsidiary of Ryerson (“Merger Sub”), and Olympic Steel, Inc., an Ohio corporation (“Olympic”), pursuant to which, subject to the terms and conditions of the Merger Agreement, Merger Sub will merge with and into Olympic (the “Merger”), with Olympic surviving the Merger as a wholly owned subsidiary of Ryerson. All defined terms used in this summary of the Merger Agreement that are not otherwise defined herein have the meanings ascribed to such terms in the Merger Agreement.

The Merger

Subject to the terms and conditions of the Merger Agreement, at the date and time the Merger becomes effective (the “Effective Time” and, such date, the “Closing Date”), each share of common stock, without par value per share, of Olympic (“Olympic Common Stock”) issued and outstanding immediately prior to the Effective Time (other than certain excluded shares) will be converted into and thereafter represent the right to receive 1.7105 shares of common stock (the “Exchange Ratio”), $0.01 par value per share, of Ryerson (the “Ryerson Common Stock”) (rounded down to the nearest whole share) and, if applicable, cash in lieu of fractional shares (the “Merger Consideration”).

Treatment of Stock-Based and Long-Term Cash Awards

As of the Effective Time, each time-based restricted stock unit with respect to shares of Olympic Common Stock granted by Olympic (each, an “Olympic RSU”) that is outstanding immediately prior to the Effective Time will be assumed by Ryerson and converted into a restricted stock unit award with respect to shares of Ryerson Common Stock (rounded down to the nearest whole share) equal to the product of (X) the number of shares of Olympic Common Stock subject to such Olympic RSU multiplied by (Y) the Exchange Ratio. Each assumed and converted Olympic RSU will remain subject to the same terms and conditions that applied to such Olympic RSU immediately prior to the Effective Time, including (1) accelerated vesting and payment as a result of the closing, if any, (2) any requirement for continued service, and (3) the holder’s right to make an election, to receive cash in lieu of shares. If a holder of an Olympic RSU elects to receive a cash settlement pursuant to the terms of an applicable Olympic RSU award agreement, such cash payment will equal the product of (x) the number of shares of Ryerson Common Stock subject to the assumed and converted restricted stock unit award multiplied by (Y) the closing price per share of Ryerson Common Stock on the Closing Date. Any such cash payments will be paid by Olympic (or one of its affiliates) through its regular payroll practices within 30 days following the Closing Date.

As of the Effective Time, each Olympic RSU that was contributed to and used to fund a participant’s account balance in Olympic’s Supplemental Executive Retirement Plan (“SERP”) will be canceled and converted into a cash amount equal to (A) the product of (X) the number of shares of Olympic Common Stock subject to such Olympic RSU, multiplied by (Y) the Exchange Ratio, multiplied by (B) the closing price per share of Ryerson Common Stock on the Closing Date. The converted cash amount will be credited to the participant’s SERP account, subject to the payment timing requirements and other terms of the SERP.

As of the Effective Time, each performance stock unit with respect to shares of Olympic Common Stock granted by Olympic (each, an “Olympic PSU”) that is outstanding immediately prior to the execution of the Merger Agreement will be canceled and converted into the right to receive a cash payment equal to (i) the product of (A) the number of shares of Olympic Common Stock subject to such Olympic PSU (assuming achievement based on actual performance for outstanding Olympic PSUs granted in 2023 and deemed target levels of performance for outstanding Olympic PSUs granted in 2024 and 2025), multiplied by (B) the Exchange Ratio, multiplied by (ii) the closing price per share of Ryerson Common Stock on the Closing Date, to be paid in cash by Olympic (or one of its affiliates) through its regular payroll practices within 30 days following the Closing Date. Each Olympic PSU that is granted following the execution of the Merger Agreement that is outstanding immediately prior to the Effective Time will be assumed by Ryerson and converted into a performance-based vesting restricted stock unit covering that number of whole shares of Ryerson Common Stock (rounded down to the nearest whole share) equal to the product of (A) the number of shares of Olympic Common Stock subject to such Olympic PSU multiplied by (B) the Exchange Ratio and will remain subject to the same terms and conditions that applied to such Olympic PSU immediately prior to the Effective Time (including continued service requirements and performance-based vesting conditions).

As of the Effective Time, each restricted stock award with respect to shares of Olympic Common Stock granted by Olympic (each, an “Olympic RSA”) that is outstanding immediately prior to the execution of the Merger Agreement will vest immediately prior to the Effective Time. Each restricted stock award granted following the date on which the Merger Agreement is executed will vest on a prorated basis based on the number of days that elapse between January 1 of the calendar year in which the grant date occurs and the Effective Time. At the Effective Time, each Olympic RSA that vests in connection with the closing will be canceled and converted into the right to receive the Merger Consideration and all outstanding and unvested Olympic RSAs will be automatically canceled and forfeited for no consideration.

As of the Effective Time, each time-based long-term cash incentive award granted under the Olympic C-Suite Long Term Incentive Plan that is outstanding immediately prior to the Effective Time will be assumed by Ryerson and remain subject to the same terms and conditions that applied to such time-based long-term cash incentive award immediately prior to the Effective Time (including any requirement for continued service).

As of the Effective Time, each performance-based cash award granted under the Olympic C-Suite Long Term Incentive Plan prior to the date on which the Merger Agreement is executed that is outstanding immediately prior to the Effective Time will be canceled and converted into the right to receive a cash payment equal to the amount that would be owed under such performance-based cash award (based on actual performance levels for outstanding performance-based cash awards granted in 2023 and deemed target levels of performance for outstanding performance-based cash awards granted in 2024 and 2025) to be paid in cash in accordance with Olympic’s (or one of its affiliates’) regular payroll practices within 30 days following the Closing Date. Each performance-based cash award that is granted following the execution of the Merger Agreement that is outstanding immediately prior to the Effective Time will be assumed by Ryerson and converted into a performance-based cash award and will remain subject to the same terms and conditions that applied to such performance-based cash award immediately prior to the Effective Time (including any requirement for continued service and performance-based vesting conditions).

At the Effective Time, each phantom stock award granted under the Olympic Amended and Restated 2007 Omnibus Incentive Plan (the “Olympic Stock Plan”) that is outstanding immediately prior to the Effective Time (“Olympic Phantom Award”) will be assumed by Ryerson and converted into a phantom stock award with phantom units (rounded down to the nearest whole unit) with respect to shares of Ryerson Common Stock equal to the product of (A) the number of phantom units subject to such Olympic Phantom Award multiplied by (B) the Exchange Ratio (“Assumed Phantom Award”) and will otherwise remain subject to the same terms and conditions that applied to such Olympic Phantom Award immediately prior to the Effective Time, provided, that (i) a portion of each Assumed Phantom Award will vest on a prorated basis based on the number of days completed in the applicable performance period through the Effective Time, and the vested portion will be paid in cash within 30 days following the Closing Date in accordance with Olympic’s (or one of its affiliates’) regular payroll practices, based on the per-share closing price of Ryerson Common Stock on the Closing Date and (ii) a portion of the Assumed Phantom Award that does not vest at the Effective Time will be assumed and remain outstanding and will remain subject to the same terms and conditions that applied to the Assumed Phantom Award immediately prior to the Effective Time (including, the requirement of continued service through the last day of the applicable performance period).

At the Effective Time, all other long-term cash awards granted under the Olympic Stock Plan will be treated in accordance with the terms of the applicable plan or award agreement, including awards outstanding under the Metal-Fab Manager Long-Term Incentive Plan and Metal-Fab Manager Retention Incentive Plan, which will remain outstanding and eligible to vest in accordance with, and subject to, the terms thereof, including (i) a portion of the award will vest on a prorated based on the number of days in the performance period that have been completed on the Closing Date and (ii) the portion of the award that does not vest at the Effective Time will continue to be outstanding and subject to the same terms and conditions that applied prior to the Effective Time (including continued service requirements through the last day of the applicable performance period). The vested portion of any such award will be paid in cash within 30 days following the Closing Date in accordance with Olympic’s (or one of its affiliates’) regular payroll practices.

Post-Closing Governance

In connection with the consummation of the Merger, Ryerson will increase the size of Ryerson’s board of directors (the “Ryerson Board”) to 11 directors, consisting of seven incumbent directors of Ryerson and four directors designated in writing by Olympic and reasonably acceptable to Ryerson at least ten business days prior to the closing of the Merger from among the directors then serving on the Olympic Board (collectively, the “Olympic Director Nominees”). In the event that the Closing occurs prior to the mailing of the proxy statement for Ryerson’s annual meeting of stockholders for 2026, Ryerson has agreed to take such actions as may be necessary to nominate each Olympic Director Nominee to the Ryerson Board, to the extent such Olympic Director Nominee’s term expires as of Ryerson’s annual meeting of stockholders for 2026.

In addition, in connection with the consummation of the Merger, Ryerson will take all actions necessary to cause Richard Marabito to be appointed as the President and Chief Operations Officer of Ryerson, Andrew Greiff to be appointed as the Executive Vice President of Ryerson and President of Olympic, Richard Manson to be appointed the Senior Vice President of Finance of Ryerson and Zachary Siegal to be appointed as the Senior Vice President of Business Development of Ryerson.

Conditions to the Merger

Completion of the Merger is subject to the satisfaction or waiver of certain conditions including (a) the adoption of the Merger Agreement by the Olympic shareholders; (b) the approval of the issuance of shares of Ryerson Common Stock in connection with the Merger by Ryerson’s stockholders; (c) the effectiveness of Ryerson’s registration statement on Form S-4; (d) the approval for listing the shares of Ryerson Common Stock issuable to the stockholders of Olympic pursuant to the Merger Agreement on the NYSE; (e) the receipt of approvals under the HSR Act; (f) the absence of any law or order prohibiting the consummation of the Merger; (g) a customary “bringdown” of Ryerson’s and Olympic’s representations and warranties; (h) compliance by Ryerson and Olympic with the covenants in the Merger Agreement to the applicable standard set forth therein, (i) the receipt of certain legal opinions as to tax matters by the parties and (j) the absence of a material adverse effect on either Ryerson or Olympic.

Representations, Warranties and Covenants

The Merger Agreement contains customary representations and warranties of Ryerson and Olympic relating to their respective businesses and public filings. The Merger Agreement also contains customary pre-closing covenants, including the obligation of Ryerson and Olympic to conduct their businesses in the ordinary course of business consistent with past practice and to refrain from taking certain specified actions without the consent of the other party.

Ryerson and Olympic have each agreed to customary non-solicitation obligations related to soliciting or engaging in any discussions or negotiations regarding competing proposals. Notwithstanding such non-solicitation obligations, prior to obtaining stockholder approval and under certain specified circumstances, the Ryerson Board or the Olympic Board, in each case, may change its recommendation of the transaction and Olympic may terminate the Merger Agreement in connection with any such change in recommendation of the Olympic Board.

Termination

The Merger Agreement contains provisions granting each of Ryerson and Olympic the right to terminate the Merger Agreement under specified circumstances, including: (a) if a permanent legal prohibition enjoins the consummation of the Merger; (b) if the Merger is not completed by April 28, 2026 (which date may be extended to July 28, 2026 if certain regulatory approvals have not been obtained); (c) if either party fails to obtain stockholder approval; (d) by Olympic, if, prior to Olympic receiving shareholder approval, Olympic enters into a definitive written agreement providing for the consummation of a Superior Proposal (as defined in the Merger Agreement) in accordance with Section 5.4 of the Merger Agreement; (e) by either Olympic or Ryerson, as applicable, if the other party has breached its representations or warranties or failed to perform its covenants in the Merger Agreement in a way that would entitle the party seeking to terminate the Merger Agreement not to consummate the Merger, subject to cure rights of the breaching party; (f) by Olympic if Ryerson’s board of directors makes a Parent Adverse Recommendation Change; (g) by Ryerson, if Olympic’s board of directors makes a Company Adverse Recommendation Change; or (h) by either Olympic or Ryerson, as applicable, if the other party committed a willful and material breach of its non-solicitation obligations.

If the Merger Agreement is terminated due to Ryerson’s board of directors changing or withdrawing its recommendation in connection with the Merger, or due to Ryerson committing a willful and material breach of its non-solicitation obligations, Ryerson will be required to pay to Olympic $15 million. If the Merger Agreement is terminated due to Olympic’s board of directors changing its recommendation in connection with the Merger, or due to Olympic committing a willful and material breach of its non-solicitation obligations, then Olympic will be required to pay Ryerson $15 million. In addition, if the Merger Agreement is terminated due to either party’s failure to obtain stockholder approval (and Ryerson’s board of directors has not changed or withdrawn its recommendation in connection with the Merger), Ryerson or Olympic, as applicable, will be required to reimburse the other party for its expenses incurred in connection with the transaction in an amount not to exceed $10 million.

The Merger Agreement is attached hereto as Exhibit 2.1 and is incorporated herein by reference. The foregoing description does not purport to be complete and is subject to and qualified in its entirety by reference to the Merger Agreement.

The Merger Agreement has been included to provide securityholders and investors with information regarding its terms. It is not intended to provide any other factual information about Ryerson, Olympic or any other person. The representations, warranties and covenants contained in the Merger Agreement were made solely for purposes of the Merger Agreement and as of specific dates, were solely for the benefit of the parties to the Merger Agreement, may be subject to limitations agreed upon by the contracting parties, including being qualified by confidential disclosures made for the purposes of allocating contractual risk between the parties to the Merger Agreement instead of establishing these matters as facts, and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to securityholders. Securityholders and investors are not third-party beneficiaries under the Merger Agreement and should not rely on the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of Ryerson or Olympic. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in Ryerson’s or Olympic’s public disclosures.
