Atrion Reports Third Quarter Results

Diluted EPS Increases by 25%

ALLEN, TX -- (Marketwire - November 02, 2011) - Atrion Corporation (NASDAQ: ATRI) today announced that for the third quarter of 2011 diluted earnings per share were up 25% and revenues were up 12% compared to the results for the third quarter of 2010.

Atrion's revenues for the quarter ended September 30, 2011 totaled $30.5 million compared with $27.2 million for the same period in 2010. On a diluted per share basis, earnings for the period increased to $3.33 as compared to $2.66 for the same quarter of last year. Net income for the third quarter totaled $6.8 million compared to $5.4 million in last year's third quarter.

Commenting on the results of the third quarter of 2011 compared to the same period of 2010, David Battat, President and CEO, said, "I am very pleased with the Company's performance in the recent quarter. Revenues were higher in all of our major product categories, with exports growing even more robustly than domestic sales, leading to an overall increase in sales of $3.3 million in the quarter, compared with the same period last year." Mr. Battat added, "During the quarter we increased our inventory by $2.3 million, primarily for finished goods, to increase safety stock levels of certain products that were unexpectedly reduced due to higher demand and raw material supply issues. Quality and customer service are key aspects of our value proposition. This includes the ability to supply key products even in the face of unanticipated events. The cost of keeping safety stocks is well outweighed by the favorable impact on customer relationships. We anticipate some further build-up of inventories in the fourth quarter to meet target levels. During the third quarter, we also expended some $2.6 million for equipment purchases, a level of spending that we expect to continue through the remainder of the year and most of 2012 in anticipation of future capacity needs." Mr. Battat concluded, "Despite the high level of expenditures for inventory and equipment in the quarter and spending $1.5 million to repurchase our common stock, the Company increased its cash and investments by $5.0 million, to a total of $52.7 million as of September 30, 2011."

Revenues for the first nine months of 2011 of $92.2 million were 13% higher than revenues of $81.9 million for the first nine months of 2010. Diluted earnings per share for the nine months ended September 30, 2011 increased 33% to $10.17 from $7.65 in the comparable 2010 period.
