CLEVELAND, May 6, 2011 (GLOBE NEWSWIRE) -- Olympic Steel, Inc., (Nasdaq:ZEUS), a national metals service center, today announced its financial results for the first quarter ended March 31, 2011.

Net sales for the first quarter of 2011 totaled $294.4 million, a 75.3% increase from the $167.9 million for the first quarter of 2010. Tons sold in the first quarter of 2011 increased 43.3% to 317 thousand from 221 thousand in the first quarter of 2010. First quarter 2011 net income totaled $10.3 million, or $0.94 per diluted share, compared to net income of $1.7 million, or $0.16 per diluted share, for last year's first quarter. 

Commenting on the results, Chairman and Chief Executive Officer Michael D. Siegal stated, "We are extremely pleased with our strong first quarter sales and earnings, our best quarterly results since the third quarter of 2008. We continue to gain market share, and we are experiencing strong momentum as the industrial recovery continues.  Our first quarter shipments increased year over year by 43.3%, almost doubling the pace of the market increase in total steel shipments of 23.5%, as reported in the Metals Service Center Institute's March 2011 Metals Activity Report. We have made timely investments during the economic downturn in new geographies and equipment to service our growing customer demands, including new location startups in Gary, Indiana; Mount Sterling, Kentucky; Monterrey, Mexico; and Kansas City, Missouri. Our healthy balance sheet, low debt levels and focus on cash turnover provide us with a strong foundation for continued growth and value creation as the market recovery strengthens."

Olympic Steel's Board of Directors approved a regular quarterly cash dividend of $0.02 per share to be paid to shareholders of record as of June 1, 2011, and distributed on June 15, 2011.
