CLEVELAND, Aug. 4, 2011 (GLOBE NEWSWIRE) -- Olympic Steel, Inc., (Nasdaq:ZEUS), a national metals service center, today announced its financial results for the second quarter and six months ended June 30, 2011.

Net sales for the second quarter of 2011 totaled $299.0 million, a 41% increase from the $212.8 million for the second quarter of 2010. Tons sold in the second quarter of 2011 increased 13% to 285 thousand from 252 thousand in the second quarter of 2010. Second quarter 2011 net income increased 144% to $7.9 million, or $0.73 per diluted share, compared to net income of $3.3 million, or $0.30 per diluted share, in last year's second quarter. Second quarter 2011 results include $941 thousand of non-recurring pretax expenses related to the Company's acquisition of Chicago Tube and Iron (CTI), which closed in the third quarter on July 1, 2011.

Net sales for the first half of 2011 totaled $593.4 million, a 56% increase from the $380.7 million for the first six months of 2010. Tons sold in the first half of 2011 increased 27% to 603 thousand from 474 thousand in the first half of 2010. First half 2011 net income more than tripled to $18.3 million, or $1.67 per diluted share, compared to net income of $5.0 million, or $0.45 per diluted share, for last year's first half. 

Commenting on the results, Chairman and Chief Executive Officer Michael D. Siegal stated, "We are pleased with our strong 2011 sales and earnings results, and our consistent gain in market share since 2010. Our first half 2011 shipments increased year over year by 27%, exceeding the pace of the market increase in total steel shipments of 19%, as reported in the Metals Service Center Institute's June 2011 Metals Activity Report. We have made timely investments during the economic downturn in new products, geographies and equipment to service our growing customer demands.  Our July 1, 2011 acquisition of CTI accelerates our market share growth and is expected to be immediately accretive to our earnings. CTI's 2011 projected annual revenues approximate $225 million. We also successfully continued our new location startups in Gary, Indiana; Mount Sterling, Kentucky; Monterrey, Mexico; Kansas City, Missouri; and most recently added locations in Roseville, Minnesota; and Streetsboro, Ohio. Our strong balance sheet and new five-year, $335 million credit facility provide us with a strong foundation for continued growth and value creation."

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 September 1, 2011, and distributed on September 15, 2011.
