  Atrion Reports Second Quarter Results; Diluted EPS Increases by 36%

    ALLEN, Texas--(BUSINESS WIRE)--July 29, 2005--Atrion Corporation
(Nasdaq:ATRI) today announced that for the second quarter of 2005
revenues were up 10% and diluted earnings per share were up 36%
compared to the results of the second quarter of 2004.
    Commenting on the Company's results, Emile A. Battat, Chairman and
CEO, said, "We are very pleased with the strong increase in sales and
especially that all our product areas, cardiovascular, fluid delivery,
ophthalmology, and other products, contributed to this growth. The
increase in sales, coupled with continued favorable mix toward
higher-margin products, led to a 52% increase in operating income in
the second quarter as compared to the same period last year." Mr.
Battat added, "The Company continued a program initiated last year to
purchase critical raw materials in larger volumes to take advantage of
quantity discounts and to hedge against further price increases. In
addition we began to increase our inventory of finished goods to
reflect increasing sales and to assure uninterrupted deliveries to our
customers when we relocate our Florida facility next year to a new
plant in St. Petersburg, Florida. These actions were the primary
reason for the increase in inventory of $2.4 million during the second
quarter, and the $3.4 million increase since the beginning of the
year."
    Atrion's revenues for the quarter ended June 30, 2005 totaled
$18,102,000 compared with $16,417,000 in the same period in 2004. On a
diluted per share basis, earnings for the period increased to $1.18 as
compared to $.87 in the same quarter of last year. Both periods
included residual earnings of $.09 per share from operations that were
discontinued in 1997. Operating income for the current-year period
totaled $3,131,000 compared to $2,064,000 in last year's second
quarter.
    Revenues for the first six months of 2005 of $36,747,000 were 11%
higher than revenues of $33,206,000 in the first half of 2004. Diluted
earnings per share for the first half of 2005 were $2.41 versus $1.57
in the first six months of 2004. Both periods included $.09 per share
from discontinued operations.
    Atrion Corporation designs, develops, manufactures, sells and
distributes products and components primarily to medical markets
worldwide.
