MOCON Announces First Quarter Results

MINNEAPOLIS, MN, April 29, 2004 – MOCON, Inc.  (Nasdaq:MOCO) today reported revenue and earnings for the quarter ending March 31, 2004.

Sales for the first quarter of 2004 were $5,753,000, an increase of 14 percent compared to $5,029,000 for 2003. Net income was $336,000, a 45 percent decrease compared to $607,000 in the first quarter of 2003. Net income per share was 6 cents (diluted) in the first quarter of 2004, a 45 percent decrease compared to 11 cents (diluted) for the same period in 2003.

Sales for the first quarter represent a new record for the Company and were positively impacted by the $863,000 in net additional revenue related to the acquisition of Paul Lippke Handels- GmbH (Lippke). Operating income for the first quarter was negatively affected by acquisition related charges including amortization of $57,000 related to purchased backlog, write-off of additional costs assigned to finished goods inventory under purchase accounting rules of $96,000, and ongoing amortization related to various other purchased intangibles of $44,000. The Company also incurred during the quarter one-time costs associated with the relocation of the Company’s Lab Connections subsidiary to Round Rock, Texas, totaling $78,900 and additional costs associated with the consolidation of the Company’s Baseline subsidiary manufacturing operations to Minneapolis, Minnesota. We believe both of these manufacturing consolidations will positively impact future operating income as reduced costs and increased operating efficiencies are realized. Bookings for the first quarter of 2004 were a record $6,580,000 which includes $881,000 in net additional bookings related to Lippke.

“We are pleased to report record revenue in the first quarter of 2004,” commented Robert L. Demorest, MOCON President and CEO. Mr. Demorest continued, “The acquisition of Lippke has had a positive impact on our first quarter revenue, and despite some of the initial amortization expenses relating to purchased backlog and revalued inventory which primarily are expected to affect first half 2004 expenses, we expect Lippke to have a positive impact on both revenues and operating income for the year as a whole.”

We continue to maintain a strong balance sheet, with cash and current and non-current marketable securities totaling $6,789,000, and no long-term debt. Total cash and marketable securities decreased slightly during the quarter after payment of a first quarter dividend totaling $351,000 and payment of the base purchase price of $802,688 for the acquisition of Lippke.
