COMPANY COMMENTS

John A. Kraeutler, Chief Executive Officer, said, “Revenue growth for the first quarter of 2010 was up due to strength in the U.S. Diagnostics business, with the greatest contribution coming from the sale of respiratory tests, especially influenza, along with continued growth in the foodborne category.   C. difficile sales were weaker due to increased competition from new immunoassays as well as emerging molecular methods, plus distributor buying patterns.  We are expecting flat sales in this product line until the launch of our new illumigene™ molecular-based technology platform later this fiscal year.  In addition, Meridian Life Science began the year with increased organic growth and this business unit is expecting a strong sales year.  Meridian Bioscience Europe, which recently launched two new products into the Italian market, reported increased sales due primarily to positive currency effects.  Currency adjusted sales for MBE were flat versus last year despite a strong start in October and November.

Overall, gross profit margin for the quarter of 60% was lower than plan due to the H1N1 pandemic driving a higher sales volume of lower margin, OEM influenza and RSV tests.  Offsetting the downward pull on margins were our TRU Flu® and TRU RSV® tests which comprised more than 40% of unit sales in this category.  Operating income margin exceeded 32% as we continued to control spending and focus on efficiency.

Notably, this month we began our formal clinical trials for our illumigene C. difficile product, our first DNA amplification test utilizing the loop amplification (LAMP) technology licensed from Eiken Chemical Co. of Japan.  These trials are expected to last approximately 8 weeks and we plan to submit our 510k for FDA marketing clearance in April of this year.  We are encouraged by our preliminary trials of illumigene as well as the response from our key customer previews.  We are continuing to invest in this development program and anticipate launching additional illumigene tests in the future.  Barring any unforeseen delays, we are now targeting revenue contributions from the illumigene C. difficile product during the second half of fiscal 2010.

The outlook for fiscal 2010 is bright. Our Diagnostics business units continue to add market share and improved profitability in respiratory testing. The growth of foodborne testing continues at double-digit rates and our managed care programs are generating strong H. pylori demand. New products, new technologies and potential acquisitions are likely to drive further growth this year. The resources that we have applied to our Life Science business are producing growth along with enhanced profitability. Our commitment to international growth is being realized, especially through our new distribution partners."

William J. Motto, Executive Chairman of the Board, said, “Fiscal 2010 started strong primarily due to increased demand for upper respiratory tests, improved operating results at our Life Science unit, and continued growth in foodborne tests.  We are maintaining our previously issued fiscal 2010 guidance of net sales in the $160 million to $165 million range and per share diluted earnings between $0.90 and $0.95.  Our cash dividend declared for the first quarter reflects the increased indicated annual rate of $0.76 per share, up 12% from the prior fiscal year.

We look forward to the commercial introduction of our illumigene molecular-based platform later this fiscal year, as well as other new product introductions and continued efficiency improvements.  Our financial condition is sound and our cash flow strong. As always, we continue to investigate potential external growth opportunities through acquisitions and alliances.”

Forward Looking Statements

The Private Securities Litigation Reform Act of 1995 provides a safe harbor from civil litigation for forward-looking statements accompanied by meaningful cautionary statements.  Except for historical information, this report contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, which may be identified by words such as "estimates", "anticipates", "projects", "plans", "seeks", "may", "will", "expects", "intends", "believes", "should" and similar expressions or the negative versions thereof and which also may be identified by their context.  Such statements, whether expressed or implied, are based upon current expectations of the Company and speak only as of the date made.  The Company assumes no obligation to publicly update or revise any forward-looking statements even if experience or future changes make it clear that any projected results expressed or implied therein will not be realized.  These statements are subject to various risks, uncertainties and other factors that could cause actual results to differ materially, including, without limitation, the following: Meridian's continued growth depends, in part, on its ability to introduce into the marketplace enhancements of existing products or new products that incorporate technological advances, meet customer requirements and respond to products developed by Meridian's competition.  While Meridian has introduced a number of internally developed products, there can be no assurance that it will be successful in the future in introducing such products on a timely basis.  Ongoing consolidations of reference laboratories and formation of multi-hospital alliances may cause adverse changes to pricing and distribution.  Recessionary pressures on the economy and the markets in which our customers operate, as well as adverse trends in buying patterns from customers can change expected results.  Costs and difficulties in complying with laws and regulations administered by the United States Food and Drug Administration can result in unanticipated expenses and delays and interruptions to the sale of new and existing products.  Changes in the relative strength or weakness of the U.S. dollar can also change expected results.  One of Meridian's main growth strategies is the acquisition of companies and product lines.  There can be no assurance that additional acquisitions will be consummated or that, if consummated, will be successful and the acquired businesses successfully integrated into Meridian's operations.  The Company cannot predict the possible effects of potential healthcare reform in the United States and similar initiatives in other countries on its results of operations.  In addition to the factors described in this paragraph, Part I, Item 1A Risk Factors of our Form 10-K contains a list and description of uncertainties, risks and other matters that may affect the Company.
