Ryerson Holding, the second largest metal distributor in North America, filed on Tuesday with the SEC to raise up to $300 million in an initial public offering. The Chicago, IL-based company had previously filed in April 2010 to raise $400 million by offering 23.5 million shares at a price range of $16 to $18 before postponing the deal due to market conditions. Ryerson was founded in 1842 and booked $3.9 billion in sales last year. It plans to list on the NYSE under the symbol RYI. BofA Merrill Lynch is now the sold underwriter on the deal, for which updated pricing terms and timing were not disclosed.
