MOCON Announces Results for the Second Quarter 2013

MINNEAPOLIS, MN, August 30, 2013 — MOCON, Inc. (NASDAQ: MOCO) today reported sales of $13.7 million for the second quarter ended June 30, 2013, an increase of 4 percent compared to $13.2 million for the same quarter in 2012.  The net income for the second quarter was $802,000, or $0.14 per diluted share, compared to a net loss of $142,000 or ($0.03) per diluted share, in the second quarter of 2012.  Six-month sales totaled $28.1 million, an increase of 26 percent compared to $22.4 million during the first six months of 2012.  Net income and diluted earnings per share were $1.7 million and $0.29, respectively, for the first half of 2013, compared to $679,000 and $0.12 for the same period in 2012.  Year-to-date amounts for 2012 included only three months of Dansensor’s results, which was acquired in April 2012.

The sales increase in the current quarter compared to the same quarter in 2012 was attributable primarily to our Industrial Analyzers and Other segment, which recorded a 23 percent increase in revenues.  This increase was driven by sales of environmental monitoring instruments due to increased regulatory concerns and sales of instruments for oil and gas exploration, primarily in the Middle East.  Sales in our Permeation and Package Testing segments were comparable to the prior year second quarter.

The company-wide gross margin of 56 percent in the second quarter 2013 was slightly lower than the company’s historical levels, although was an improvement from the prior year second quarter margin of 48 percent.  The lower than expected percentage in the current quarter was due primarily to a shift in product mix to a higher percentage of our package testing instruments, which traditionally carry lower margins.  The lower than normal margin in the prior year second quarter was due to purchase accounting adjustments that were required in connection with the Dansensor acquisition. Selling, general and administrative expenses in the current quarter are slightly higher compared to the same period last year primarily due to higher wage and benefit costs.  Our effective tax rate of 3 percent in the current quarter was significantly lower than historical levels due to a change in the income tax rates in Denmark which allowed for a discrete positive adjustment of $258,000 to income tax expense in the second quarter 2013.

“We are encouraged by the fact that our international sales increased 13 percent in the current quarter compared to last year, as both Europe and Asia showed strong improvement.  Our domestic sales in the current quarter were lower than last year but still ahead on a year-to-date basis,” said Robert L. Demorest, MOCON President and CEO.  “While we are satisfied with our top line performance for the first six months this year, we are committed to improving our bottom line by striving to increase our gross margins and reducing our overhead expenses as a percentage of revenues.”
