SAN CLEMENTE, Calif., July 19, 2010 (GLOBE NEWSWIRE) -- ICU Medical, Inc., (Nasdaq:ICUI), a leading low cost manufacturer of safe medical connectors, custom medical products and critical care devices, announced results for the second quarter and six months ended June 30, 2010.

Second quarter of 2010 revenue increased 29.0% to $68.9 million, compared to $53.4 million in the same period last year. Net income for the second quarter of 2010 was $7.7 million, or $0.56 per diluted share, as compared to net income of $5.7 million, or $0.38 per diluted share, for the same period last year.

For the six months ended June 30, 2010, revenue increased 23.7% to $133.2 million, compared to $107.7 million in the same period last year. Net income for the six months ended June 30, 2010, was $12.0 million, or $0.86 per diluted share, compared to net income of $12.8 million, or $0.85 per diluted share, for the same period last year.

Scott Lamb, ICU Medical's Chief Financial Officer, said, "We are pleased to report a strong second quarter, highlighted by double-digit revenue growth in all of our major product lines and improved profitability. In addition, our products showed robust demand worldwide as our domestic distributor and direct sales grew 136% while international sales were up 65% year over year. Gross margins improved consecutively by 490 basis points to 46.7% primarily due to the transfer of critical care finished goods manufacturing from Hospira to us during the second quarter and overall improvements in manufacturing efficiencies at our factories.

"The transition of the critical care operations that we acquired from Hospira last August is in line with our original plan and we look forward to capitalizing on additional opportunities for these products. We are also nearing completion of our new manufacturing plant in Slovakia and expect to commence European production during the fourth quarter of this year. Our distribution partnerships coupled with our expanded direct sales force should continue to make strong contributions to the top-line and have us positioned for further global expansion.

"Going forward, we plan to leverage our strong operating cash flow to finance our immediate capital needs, continue to develop our new product pipeline and enhance value for our shareholders, including through the use of our new $40 million stock buyback program."

The Company ended the second quarter with a healthy balance sheet. As of June 30, 2010, cash, cash equivalents and investment securities totaled $83.1 million and working capital was $153.0 million. Additionally, the Company generated operating cash flow of $7.9 million for the second quarter of 2010.

Based on the current business trends, management has raised the Company's revenue and earnings per share guidance range for the full fiscal year of 2010. Revenue is now expected to be in the range of $270 million to $275 million, up from the previous guidance of $265 million to $275 million.
