Atrion Reports Results for Fourth Quarter and Full Year 2018

ALLEN, Texas, Feb. 26, 2019 (GLOBE NEWSWIRE) -- Atrion Corporation (NASDAQ: ATRI) announced today that for the fourth quarter of 2018 revenues were $34.9 million compared to $34.0 million in the same period of 2017, net income was $7.7 million compared to $8.6 million in the prior-year period, and diluted earnings per share were $4.17 compared to $4.66 in the prior-year period. For the full year 2018 compared to 2017, Atrion increased revenues to $152.4 million from $146.6 million, net income was $34.3 million compared to $36.6 million, and diluted earnings per share were $18.44 compared to $19.71.

David Battat, President & CEO, commenting on the results for the fourth quarter and the full year 2018 as compared to the prior-year periods, said, "We are pleased that our revenues were up 3% in the quarter and 4% for the full year despite the significant decline in Ophthalmic sales that was discussed in prior press releases. Those sales were lower by 17% in the quarter and 23% for the full year.” Mr. Battat continued, “Full year comparisons of net income and diluted EPS are distorted because our 2018 tax rate was higher than the prior year due to significant, non-recurring tax benefits in 2017.”

Mr. Battat continued, “Although operating income showed a small year-over-year improvement, operating income for 2018 was 27% of sales, a testament to both the clinical demand for our products and the efficiency of our operations. As a result, cash flow from operations in 2018 funded an increase of $6.4 million in working capital, $17.5 million in manufacturing investments and $9.4 million in dividend payments. In addition cash and short and long term investments increased by $14.8 million during the year, bringing the total as of December 31, 2018 to $89.5 million.”

Commenting on the outlook for 2019, Mr. Battat said, “We anticipate that Ophthalmic sales will stabilize in the second quarter of this year, while other major product areas will begin to benefit from new product releases. We are particularly excited that, after a multi-year development process, the latest generation of our flagship cardiovascular technology, the Myocardial Protection System (MPS 3), is undergoing a limited market release in Canada, and we hope to have FDA clearance for the U.S. market this year. The MPS 3 is a significant step forward in our cardiovascular portfolio, expanding the benefits of this platform to both clinicians and patients. We are confident that our MPS 3 will remain the market leading technology in its niche for several years to come.”
