Sales for the quarter totaled $44,434,000 compared with $38,116,000 a year earlier, an increase of 16.6%. Net income for the quarter was $2,417,000 or $.43 per share on a diluted basis compared to $2,320,000 or $.40 per share on a diluted basis in 2006. For the six months ended June 30, 2007, sales were $87,777,000 compared to $74,905,000 for the same period in 2006, an increase of 17.2%. Net income for the six months of 2007 increased to $4,661,000 or $.82 per share on a diluted basis from $4,469,000 or $.78 per share on a diluted basis in the year-ago period. David Brown, President and CEO stated: "We believe that the productivity initiatives we began implementing during the first quarter of 2007 are beginning to contribute positively to our operating results. During the quarter net income increased $97,000 or 4.2%. Significantly, however, operating income increased $530,000 or 12.2% over the same quarter in 2006. This brings the increase in net income and operating income for the six months 2007 versus 2006 to $192,000 or 4.3% and $1,089,000 or 13.1%, respectively. We believe these trends will continue as we persist in our efforts to better manage our labor requirements as we implement and leverage new technology. Sales in the first half of 2007, while up 17.2% were driven by our acquisitions from 2006. Internal sales, or sales at laboratories owned over one year, declined 1.3%. We continue to aggressively pursue acquisitions and remain focused on capitalizing on our Company's strengths. To do this we intend to continue to differentiate our laboratories through their local presence and their commitment to unsurpassed service, high quality products and prompt delivery."
