MOCON Q2 2012 Revenue Increases 45 Percent Following PBI-Dansensor Acquisition

MINNEAPOLIS, MN, August 14, 2012 — MOCON, Inc. (NASDAQ: MOCO) today reported sales of $13.2 million for the second quarter ended June 30, 2012, versus $9.1 million in the comparable quarter in 2011, an increase of 45 percent, in part attributable to the addition of $4.7 million in sales from PBI-Dansensor A/S, which was acquired on April 2, 2012.

The net loss for the quarter was $142,000, or $0.03 per diluted share, compared to net income of $1.2 million or $0.22 per diluted share, in the second quarter of 2011.  Excluding certain pro forma adjustments related to the acquisition of Dansensor and non-cash stock option expenses, the company’s earnings totaled $1.2 million, or $0.21 per diluted share, versus $0.23 per diluted share in the comparable period of 2011.  A full reconciliation between GAAP and non-GAAP financial measures reflecting the impact of certain discrete items relating to the Dansensor acquisition and non-cash stock option expense is included with the company’s financial tables.

“While we are disappointed to report a small loss for this quarter, our results were significantly affected by one-time expenditures attributable to our Dansensor acquisition,” said Robert L. Demorest, MOCON President and CEO.  “We are focused on the strategic impact this acquisition has for MOCON.  With the addition of Dansensor’s product line, we are now one of the premier worldwide providers of instruments for the modified atmosphere packaging market.  We are pleased with the progress we have made with the integration of Dansensor into our organization, and are continuing to evaluate areas where we can realize additional synergies and cost savings.”

Gross margin of 48 percent in the quarter was significantly lower than the company’s historical levels.  This was primarily due to the recognition of costs relating to purchase accounting adjustments arising out of the Dansensor acquisition.  Selling, general and administrative expenses in the second quarter 2012 included costs incurred in connection with the acquisition of Dansensor totaling approximately $386,000.

Six-month sales totaled $22.4 million, an increase of 23 percent compared to $18.2 million during the first six months of 2011.  Net income and diluted earnings per share were $679,000 and $0.12, respectively, for the first half of 2012, compared to $2.5 million and $0.46 for the same period in 2011.  Excluding certain pro forma adjustments related to the acquisition of Dansensor and non-cash stock option expenses, the company’s earnings totaled $2.0 million, or $0.34 per diluted share, versus $0.48 per diluted share in the comparable period of 2011.

Sales of the company’s gas analysis products increased 13% for the quarter as shipments of total hydrocarbon analyzers primarily to the oil and gas exploration market were strong.  MOCON’s permeation products and service group experienced a 16 percent decline in sales for the quarter due to an unusually strong quarter in the prior year and economic concerns in many parts of the world.

With the addition of Dansensor, whose primary markets are in Europe, the company’s total foreign sales for the current quarter amounted to 63 percent of consolidated sales versus to 57 percent for the second quarter in 2011.  The company’s total foreign and domestic consolidated sales increased 62 percent and 24 percent, respectively, in the current quarter relative to the comparable quarter in 2011.
