IDEXX Laboratories, Inc. (Nasdaq: IDXX), today reported that revenue for the first quarter of 2006 increased 10% to $168.2 million from $152.4 million for the first quarter of 2005. Earnings per diluted share for the quarter ended March 31, 2006 were $0.55, compared to $0.51 for the same period in the prior year.


Net income for 2006 includes the after-tax impact of share-based compensation expense of $0.07 per diluted share, including the impact of SFAS No. 123(R). Net income for the quarter ended March 31, 2005 included acquisition integration costs of $0.02 per diluted share. Adjusting the results for both periods to exclude the effects of these specified items, adjusted non-GAAP earnings per diluted share grew approximately 15%. Management believes adjusted earnings per diluted share is a useful non-GAAP financial measure to evaluate the results of ongoing operations, excluding significant specified items, period over period, and therefore believes that investors may find this information useful in addition to the GAAP results.


Companion Animal Group ("CAG") revenue for the first quarter of 2006 increased 12% to $139.4 million from $124.9 million for the first quarter of 2005 primarily due to higher sales in all CAG product and service categories. Incremental sales from businesses acquired during 2005, consisting of veterinary reference laboratories and a digital radiography business, contributed approximately 2% to CAG revenue growth, while the impact of foreign exchange reduced growth by 2%.


Food Diagnostics Group ("FDG") revenue for the first quarter increased 14% to $16.7 million from $14.7 million for the first quarter of 2005 primarily due to higher livestock diagnostics sales volume. The unfavorable impact of foreign currency decreased FDG revenue growth by 7%.


Water segment revenue for the first quarter decreased 6% to $12.1 million from $12.8 million for the first quarter of 2005 primarily due to lower worldwide sales volume. The unfavorable impact of foreign currency contributed 2% to the decline.


"We are pleased with the fundamentals of the business, with very good growth in most of the businesses contributing to 13% growth, adjusting for the impact of currency, and good profit realization as a result," said Jonathan Ayers, Chairman and CEO. "Our confidence leads us to increase our financial outlook for the year."


Additional operating results


Gross profit for the first quarter of 2006 increased $9.9 million, or 13%, to $86.0 million from $76.1 million for the first quarter of 2005. As a percentage of revenue, gross profit increased to 51% from 50% in the first quarter of 2005. The increase in the gross profit percentage was attributable, in part, to relatively favorable pricing in certain businesses; lower overall manufacturing and purchased materials costs including lower cost of instruments and consumables; and the absence in 2006 of the acquisition integration costs incurred in the first quarter of 2005.


Research and development ("R&D") expense for the quarter was $12.7 million compared to $9.8 million for the first quarter of 2005. R&D expense as a percentage of total revenue increased to 8% from 6% in the first quarter of 2005. The increase in R&D expense resulted from increased product development spending related primarily to IDEXX VetLab(R) instrumentation.


Selling, general and administrative ("SG&A") expense for the quarter was $46.4 million, or 28% of revenue, compared to $40.2 million, or 26% of revenue, in the first quarter of 2005. The increase in SG&A expense as a percentage of total revenue was primarily due to the change in accounting for share-based compensation beginning on January 1, 2006.


Outlook


The Company offers the following revised guidance for the full year of 2006:


* Revenue is expected to be approximately $704 to $712 million, updated


from $700 to $710 million.


* Diluted earnings per share are expected to be approximately $2.44 to


$2.52, updated from $2.40 to $2.50.

We use these supplemental non-GAAP financial measures to evaluate the


Company's comparative financial performance. The specified items that are


excluded from these non-GAAP measures are actual charges that impact net


income and cash flows, however, we believe that it is useful to evaluate


our core business performance period over period excluding these


specified items, in addition to relying upon GAAP financial measures. We


adjust 2006 GAAP financial results to exclude the after-tax impact of


share-based compensation expense in order to evaluate the Company's


performancerelative to 2005 financial results. We do not consider the pro


forma 2005 financial results that are included in our Annual Report on


Form 10-K and quarterly reports on Form 10-Q to be reasonably comparable


to 2006 financial results with respect to the impact of


share-based compensation expense due to several factors, including


changes in 2006 in the types,terms and total fair value of share-based


compensation awards; changes inthe timing of expense recognition for 2006


awards; and differences betweenperiods in income tax benefits.

Free cash flow indicates the cash generated from operations and tax

useful measure because it indicates the cash the operations of the


business are generating after appropriate reinvestment for recurring


investments in fixed assets that are required to operate the business. We


believe this is a common financial measure useful to further evaluate the


results of operations.
