RYERSON REMINDS STOCKHOLDERS: YOUR VOTE COUNTS

VOTE THE WHITE PROXY CARD

Chicago, IL, August 22, 2007 – Ryerson Inc. (NYSE: RYI) today urged stockholders to reject the Harbinger slate and vote only the white proxy card in advance of tomorrow’s annual meeting for stockholders.

Neil Novich, chief executive officer of Ryerson commented, “Tomorrow’s vote is vitally important to the future of your investment in Ryerson. A lot of information has been published over the past month and I would like to summarize the following key points you should consider when you vote.”

• Ryerson has steadily improved financial returns and in the first half of 2007 outperformed most of its peer companies.

• This financial performance has been reflected in Ryerson’s stock price, which has outperformed the peer group.

• Given industry conditions and other factors, it is appropriate to consider a sale of the company at this time.

• The board followed a deliberate, public and exhaustive process to determine the best sale price, contacting over 50 potential buyers and meeting over 30 times to determine the best outcome for stockholders.

• The $34.50 per share transaction with Platinum reflects a premium to Ryerson’s unaffected trading range; this price compares favorably with other transactions in the metal service center industry.

• Ryerson is a well successful, governed company. Ryerson’s directors have received the full endorsement of leading proxy advisory services, including ISS, while Harbinger’s slate has been rejected.

• A Harbinger controlled board could terminate the sale to Platinum without allowing you the ability to vote on the transaction. Harbinger’s nominees have not stated any plan for Ryerson nor have they endorsed the sale to Platinum. They have simply asked for control of your company.

THE FACTS SPEAK FOR THEMSELVES. For a full analysis of the facts, go to www.ryerson.com to review our latest stockholder presentation titled “Your Vote: Key Points to Consider” and read for yourself.

Vote the WHITE CARD to preserve your opportunity to vote on the sale to Platinum. DO NOT VOTE THE GREEN PROXY CARD. Only the last proxy card submitted by a stockholder will count.

Use the WHITE PROXY CARD to vote FOR Ryerson’s Board nominees TODAY—by telephone, by Internet, or by signing, dating and returning the WHITE PROXY CARD. Any stockholders with questions or requiring assistance in voting their WHITE PROXY CARD should call MacKenzie Partners at (800) 322-2885.

The Annual Meeting of Ryerson Stockholders will be held on August 23, 2007 at 8:00 a.m. Central Daylight Time at The Conrad Chicago, 521 N. Rush Street, Chicago, IL.
