Ryerson Holding Corporation Announces Closing of Secondary Offering of Common Stock by its Principal Shareholder and Concurrent Stock Repurchase

CHICAGO – February 28, 2023 – Ryerson Holding Corporation (NYSE: RYI) (the “Company” or “Ryerson”) announced today the closing of an underwritten secondary public offering of 2,486,580 shares of its common stock by an affiliate of Platinum Equity LLC (the “Selling Stockholder”). Ryerson did not offer any shares of its common stock in the offering and did not receive any of the proceeds from the sale of the shares offered by the Selling Stockholder.

Concurrently with the completion of the offering, Ryerson repurchased directly from the Selling Stockholder 1,513,420 shares of common stock. The price per share paid by the Company equaled the price at which the underwriter purchased the shares from the Selling Stockholder in the offering, net of underwriting discounts and commissions. The Company funded the share repurchase with cash on hand.

Jim Claussen, Ryerson’s Chief Financial Officer, stated “The completed secondary offering and concurrent share repurchase represent an important milestone in the continued evolution of Ryerson, where we have increased our public company share float, increased ownership to non-selling shareholders and put our authorized share buyback program to great use. This is a welcome addition to our capital allocation accomplishments over the past year, which now reflect returning to shareholders more than $120 million through dividends and share repurchases, increasing our quarterly dividend by 70 percent to $0.17 per share, and retiring the final $300 million of our outstanding high-yield debt. We would like to thank Platinum Equity for its ongoing investment and support throughout our 15-year relationship.”

The secondary offering was made pursuant to an effective shelf registration statement on Form S-3 (including a prospectus) which was filed by Ryerson with the Securities and Exchange Commission (“SEC”). You may obtain these documents for free by visiting EDGAR on the SEC website at www.sec.gov.
