FOR IMMEDIATE RELEASE

IDEXX Laboratories Announces Fourth Quarter Results

WESTBROOK, Maine, January 25, 2008— IDEXX Laboratories, Inc. (NASDAQ: IDXX), today reported that revenue for the fourth quarter of 2007 increased 27% to $245.0 million from $192.2 million for the fourth quarter of 2006. Earnings per diluted share (“EPS”) for the quarter ended December 31, 2007 were $0.40, compared to $0.38, for the same period in the prior year. Non-GAAP adjusted diluted EPS for the fourth quarter grew 29% to $0.40 from $0.31 for the fourth quarter of 2006.

“We completed another strong quarter for our companion animal business, with overall organic growth at 17% and each individual business growing at a double-digit rate, which I think speaks to the fundamental strength of our market and our business model,” said Jonathan W. Ayers, Chairman and CEO. “Of particular note, instruments had another strong placement quarter, continuing the strong trend in placement growth that we saw throughout 2007. We expect the momentum in our IDEXX VetLab instrumentation business to continue in 2008 with the launch of our two new instruments, Catalyst Dx (TM) and SNAPShot Dx (TM), both of which we expect to begin shipping in March.”

Companion Animal Group (“CAG”) revenue for the fourth quarter of 2007 increased 26% to $197.5 million from $157.0 million for the fourth quarter of 2006. Acquisitions of reference laboratories contributed 5% to growth and changes in foreign currency exchange rates contributed an additional 4%. Growth for the quarter adjusted for acquisitions and foreign currency exchange rates was 17%.

Water segment revenue for the fourth quarter of 2007 increased 17% to $17.3 million from $14.7 million for the fourth quarter of 2006 due primarily to higher sales volume, partly offset by lower average unit sales prices due to both higher relative sales in geographies where products are sold at lower average unit sales prices and greater price competition in certain geographies. Higher sales volumes resulted in part from our commencement in September 2007 of distribution of certain water testing kits manufactured by Invitrogen Corporation, which contributed 6% to revenue growth. Compared to the same period of 2006, changes in foreign currency exchange rates contributed 5% to Water revenue growth.

Production Animal Segment (“PAS”) revenue for the fourth quarter of 2007 increased 34% to $22.2 million from $16.6 million for the fourth quarter of 2006 due primarily to higher livestock diagnostics sales volume, including sales attributable to Institut Pourquier, which we acquired in March 2007. Sales of Pourquier products contributed 16% to PAS revenue growth. The favorable impact of higher sales volume was partly offset by lower average unit sales prices for products that test for transmissible spongiform encephalopathies (“TSE”) due to greater price competition. Compared to the same period of 2006, changes in foreign currency exchange rates contributed 11% to PAS revenue growth.

The accompanying financial tables provide more information concerning our revenue and other operating results for the three and twelve months ended December 31, 2007, as well as a reconciliation of non-GAAP adjusted diluted EPS to earnings per share.

Full-Year Results

Revenue for the year ended December 31, 2007 increased 25% to $922.6 million from $739.1 million for the year ended December 31, 2006. Revenue for the year ended December 31, 2007, adjusted for the impacts of acquisitions and foreign currency exchange rates, increased 14%.

Earnings per diluted share for the year ended December 31, 2007 increased 3% to $1.46 from $1.42 for the year ended December 31, 2006. Non-GAAP adjusted diluted EPS for the year ended December 31, 2007 grew 19% to $1.58 from $1.33 for the year ended December 31, 2006.

Additional Operating Results for the Fourth Quarter

Gross profit for the fourth quarter of 2007 increased $26.0 million, or 27%, to $122.2 million from $96.3 million for the fourth quarter of 2006. As a percentage of total revenue, gross profit was constant at 50%. Year-over-year, the gross profit percentage was unfavorably impacted by greater relative sales of lower margin products and services including laboratory and consulting services. Decreases in the gross margin percentage were offset by the favorable net impact of foreign currency exchange rates and higher average selling prices, resulting in part from higher relative sales of combination rapid assay products such as the SNAP^®4Dx^®,which was launched in the U.S. in September 2006.

Research and development (“R&D”) expense for the fourth quarter of 2007 was $16.8 million, or 6.8% of revenue, compared to $14.0 million, or 7.3% of revenue, for the fourth quarter of 2006. R&D expense grew primarily as a result of increased product development spending related to IDEXX VetLab^® instrumentation and to product development activities across all product and service categories.

Selling, general and administrative (“SG&A”) expense for the fourth quarter of 2007 was $68.7 million, or 28% of revenue, compared to $52.8 million, or 27% of revenue, for the fourth quarter of 2006. Year- over-year increased SG&A expense was due primarily to expanded worldwide sales, marketing and customer support resources; higher spending on information technology, facilities and other general support functions; and incremental activities associated with recently acquired businesses.

Outlook

The Company offers the following revised guidance for the full year of 2008:

· Revenue is expected to be $1.05 billion to $1.07 billion, which represents revenue growth of 14% to 16%.

· Diluted earnings per share are expected to be $1.83 to $1.87, which represents EPS growth of 25% to 28%. Excluding the impact in 2007 of acquisition-related purchase accounting and acquisition integration costs and the write-down of certain pharmaceutical assets, non-GAAP adjusted diluted EPS are projected to grow 16% to 18%.

Management believes adjusted diluted EPS is a useful non-GAAP financial measure to evaluate the results of ongoing operations, excluding significant specified events, period over period, and therefore believes that investors may find this information useful in addition to the GAAP results. 

We use these supplemental non-GAAP financial measures to evaluate the Company's comparative financial performance. The specified items that are

excluded in 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.

⁽¹⁾ We believe that the change from period to period due to specific acquisition-related purchase accounting and integration costs is not representative of ongoing operations and is not indicative of future performance. Specific acquisition-related discrete costs do not include amortization expense related to acquired intangible assets. We applied the statutory income tax rates of the applicable tax jurisdictions to calculate the after-tax impact of these discrete items. Discrete items for 2006 also include a write-down of an equity investment in one of our technology licensors. We believe the investment write-down is infrequent and is not representative of ongoing operations; IDEXX owns no other equity investments.

⁽²⁾ We believe that certain significant discrete income tax items create impacts on financial measures that are not indicative of future performance because the items are not likely to recur within a reasonable period. For 2006, the separately identified discrete income tax benefit was due to a reduction in previously accrued taxes in connection with the resolution of an Internal Revenue Service income tax audit for 2003 and 2004 in advance of the expiration of the statues of limitations.

⁽³⁾ The sum of the individual items may not equal the non-GAAP measurement due to rounding of the individual items in this presentation.

 Management believes adjusted diluted EPS is a useful non-GAAP financial measure to evaluate the results of ongoing operations, excluding significant specified events, period over period, and therefore believes that investors may find this information useful in addition to the GAAP results. 

 We use these supplemental non-GAAP financial measures to evaluate the Company's comparative financial performance. The specified items that are excluded in 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. 

⁽¹⁾ We believe that the write-down of certain pharmaceutical assets is not indicative of future performance because significant costs of a similar nature are not likely to recur within a reasonable period. We believe that we do not have other large inventory investments where the relationship of inventory to current sales volumes creates significant exposure to valuation risk. During the second quarter, we recognized a $9.1 million write-down of raw materials inventory and a $1.0 million write-off of a prepaid royalty license associated with Navigator® paste, a nitazoxanide product for the treatment of equine protozoal myeloencephalitis. We have written down these assets because product sales have been significantly lower than projected and we received notice from our third-party contract manufacturer of finished goods that the manufacturer will discontinue manufacturing the product in 2009. Due in part to an estimated production volume which is low, we believe that we will not be able to find an economically feasible replacement manufacturer and therefore that we will not be able to obtain the product after the termination of the existing manufacturing arrangement. We applied the statutory income tax rate of the applicable tax jurisdiction to calculate the after-tax impact of this discrete item.

⁽²⁾ We believe that the change from period to period due to specific acquisition-related purchase accounting and integration costs is not representative of ongoing operations and is not indicative of future performance. Specific acquisition-related discrete costs do not include amortization expense related to acquired intangible assets. We applied the statutory income tax rates of the applicable tax jurisdictions to calculate the after-tax impact of these discrete items. Discrete items for 2006 include a write-down of an equity investment in one of our technology licensors. We believe the investment write-down is infrequent and is not representative of ongoing operations; IDEXX owns no other equity investments.

⁽³⁾ We believe that certain significant discrete income tax items create impacts on financial measures that are not indicative of future performance because the items are not likely to recur within a reasonable period. For 2006, the separately identified discrete income tax benefits were composed of a tax benefit of $0.06 per diluted share due to a reduction of previously accrued taxes in connection with the resolution of an Internal Revenue Service income tax audit for 2003 and 2004 in advance of the expiration of the statutes of limitations and a tax benefit of $0.03 per diluted share due to the release of a valuation allowance on international deferred tax assets as a result of obtaining certain multi-year tax incentives and the release of a valuation allowance on international deferred tax assets as a result of a subsidiary demonstrating consistent sustained profitability.

⁽⁴⁾ The sum of the individual items may not equal the non-GAAP measurement due to rounding of the individual items in this presentation.

	Free cash flow	$	78,603		$	73,098
	Free cash flow indicates the cash generated from operations and tax benefits attributable to stock option exercises, reduced by investments in fixed assets. We feel free cash flow is a 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.
