ev3 Reports 2010 First Quarter Financial Results

First Quarter Net Sales Increase 23% to $123.9 million

First Quarter GAAP EPS Increases to $0.09

Cash and Cash Equivalents Increase to $116.8 Million

Full-Year 2010 Revenue and Earnings Guidance Increased

PLYMOUTH, Minn. — April 29, 2010 — ev3 Inc. (NASDAQ: EVVV), a global endovascular device company, today reported financial results for its fiscal first quarter and updated financial guidance for 2010. ev3’s net sales totaled $123.9 million in the first quarter of 2010 compared to $100.4 million in the same quarter of the prior year. Excluding $2.9 million of positive impact due to foreign currency exchange rates, net sales increased 21% versus the prior year quarter.

Reconciliations of non-GAAP financial measures used in this release to the most comparable U.S. GAAP measures for the respective periods can be found immediately following the detail of net sales by geography in this release.

Robert Palmisano, president and chief executive officer of ev3 Inc., commented, “We achieved another quarter of significant sales growth in both our neurovascular and peripheral vascular segments that outpaced market growth rates in U.S. and international markets. Our neurovascular segment, which grew 44% in the first quarter compared to the prior year quarter, reflects the broad penetration we are making across our entire product line and the positive response to the international launch of our Pipeline Embolization Device and Solitaire FR Revascularization Device for ischemic stroke.”

Palmisano continued, “I am especially pleased by the 13% sales growth we saw in our peripheral vascular segment during the quarter, which was led by an outstanding performance from our U.S. sales organization and the launch of our TurboHawk Plaque Excision System, TrailBlazer Support Catheter and new PowerCross PTA balloon.”

ev3’s GAAP net income for the first quarter of 2010 was $9.9 million, or $0.09 per diluted share, compared to a net loss of $(1.8) million, or $(0.02) per diluted share, in the first quarter of 2009. Non-GAAP adjusted net income in the first quarter of 2010 was $22.3 million, or $0.20 per diluted share, compared to adjusted net income of $7.1 million, or $0.07 per diluted share, in the first quarter of 2009.

Cash and cash equivalents totaled $116.8 million as of the end of the first quarter of 2010, an increase of $18.8 million compared to the end of the fourth quarter of 2009.

Palmisano concluded, “Operationally, this was another very strong quarter for ev3. In addition to sales growth, we continue to emphasize gross margin improvement and profitability as our primary objectives, so I was very pleased to see sequential quarter gross margin expansion of 50 basis points to 76.4%. We will continue to focus on improving execution, driving manufacturing efficiencies and increasing leverage.”

On a geographic basis, U.S. net sales increased 18% versus the prior year quarter. International net sales increased 31% versus the prior year quarter and 24% on a constant currency basis.

Outlook

ev3 has increased its full-year guidance and now expects fiscal year 2010 net sales to be in the range of $520 to $530 million compared to $449.1 million of net sales in 2009. Net sales growth is expected to be approximately 16% to 18%. At current average rates, foreign currency exchange rate fluctuations are expected to have a minimal impact on revenue in 2010 compared to 2009. ev3 expects non-GAAP adjusted earnings per share to be in the range of $0.87 to $0.92 per diluted share, an increase of 43% to 51% over prior year based on approximately 115.4 million shares outstanding. ev3’s adjusted net earnings per share guidance excludes estimated amortization expense of approximately $26.0 million, non-cash stock-based compensation of approximately $15.5 million, and charges relating to the estimated change in fair value of the future contingent consideration associated with the Chestnut acquisition of $17.2 million.

The company expects second quarter of 2010 net sales to be in the range of $129 to $133 million, an increase of 18% to 22% over the second quarter of 2009. At current average rates, foreign currency exchange rate fluctuations are expected to have a minimal impact on revenue growth in the second quarter of 2010. ev3 expects non-GAAP adjusted earnings per share to be in the range of $0.18 to $0.21 per diluted share, based on approximately 115.1 million shares outstanding, compared to $0.14 per diluted share in the second quarter of 2009. ev3’s non-GAAP adjusted earnings per share for the second quarter of 2010 excludes estimated amortization expense of approximately $6.5 million, non-cash stock-based compensation of approximately $3.9 million and charges relating to the estimated change in fair value of the future contingent consideration associated with the Chestnut acquisition of $8.1 million.

Use and Economic Substance of Non-GAAP Financial Measures Used by ev3 and Usefulness of Such Non-GAAP Financial Measures to Investors

ev3 uses the non-GAAP financial measures described above as supplemental measures of performance and believes these measures facilitate operating performance comparisons from period to period and company to company by factoring out potential differences caused by acquisitions, dispositions, charges not related to ev3’s regular, ongoing business, variations in capital structure, tax positions, depreciation, non-cash charges and certain large and unpredictable charges. ev3’s management uses the non-GAAP financial measures used in this release to analyze the underlying trends in ev3’s business, assess the performance of ev3’s core operations, establish operational goals and forecasts that are used in allocating resources and evaluate ev3’s performance period over period and in relation to its competitors’ operating results. Additionally, ev3’s management is evaluated on the basis of some of these non-GAAP financial measures when determining achievement of their incentive compensation performance targets.

ev3 believes that presenting the non-GAAP financial measures used in this release provides investors greater transparency to the information used by ev3’s management for its financial and operational decision-making and allows investors to see ev3’s results “through the eyes” of management. ev3 also believes that providing this information better enables ev3’s investors to understand ev3’s operating performance and evaluate the methodology used by ev3’s management to evaluate and measure such performance. ev3’s management believes that non-GAAP financial measures are useful to investors to evaluate ev3’s performance period over period and in relation to its competitors’ operating results. Because ev3 historically has reported some of these non-GAAP results to the investment community, management also believes that the disclosure of these non-GAAP measures provides consistency in ev3’s financial reporting and facilitates investors’ understanding of ev3’s historic operating trends by providing an additional basis for comparisons to prior periods.

The following is an explanation of each of the items that management excluded from one or more of the non-GAAP financial measures used in this release. ev3’s management believes that in order to properly understand the underlying business trends and performance of ev3’s ongoing operations, management has found and investors may find it useful to consider excluding the following items recorded for the first quarter of 2010 and 2009:

	•		Foreign exchange impact and estimated foreign exchange impact. The impact of foreign exchange rates is highly variable and difficult to predict. The foreign exchange impact is the impact from foreign exchange rates on current period sales compared to prior period sales using the prior period’s foreign exchange rates. Estimated foreign exchange impact is the estimated impact of foreign exchange rates on future net sales compared to prior period net sales using estimated future period foreign exchange rates.
	•		Contingent consideration. In the second quarter of 2009, ev3 acquired Chestnut Medical Technologies, Inc. (Chestnut). Under the terms of the agreement and plan of merger with Chestnut, ev3 made an initial closing payment in the amount of $79.4 million. In addition to the initial closing payment, ev3 may be obligated to make an additional contingent consideration payment of up to $75.0 million if the Food and

			Drug Administration issues a letter granting pre-market approval for the commercialization of Chestnut’s Pipeline Embolization Device in the United States pursuant to an indication to treat intracranial aneurysms on or before December 31, 2012. At each reporting date, ev3 remeasures the contingent consideration at fair value until the contingency is resolved. The change in fair value of $2.5 million for the first quarter of 2010 was recognized in ev3’s consolidated statements of operations.
	•		FoxHollow lease reserve adjustment. In the first quarter of 2009, ev3 recorded a $3.4 million adjustment to its lease reserve for leases acquired in connection with the FoxHollow acquisition. This reserve adjustment is not indicative of ev3’s ongoing operating performance.
	•		Realized gain on the divestiture of non-strategic investment assets. In the first quarter of 2009, ev3 recorded a gain of $4.1 million on the sale of certain non-strategic investment assets. This gain is not indicative of ev3’s ongoing operating performance.
	•		Non-cash stock-based compensation. ev3 excludes stock-based compensation expense from its non-GAAP financial measures primarily because such expense, while constituting an ongoing and recurring expense, is not an expense that requires cash settlement and is not used by ev3’s management to assess the core profitability of ev3’s business operations.
	•		Amortization expense. ev3 excludes amortization expense from its non-GAAP financial measures primarily because such expense, while constituting an ongoing and recurring expense, is not an expense that requires cash settlement and is not used by ev3’s management to assess the core profitability of ev3’s business operations.

Material Limitations Associated with the Use of Non-GAAP Financial Measures and Manner in which ev3 Compensates for these Limitations

Non-GAAP financial measures have limitations as analytical tools and should not be considered in isolation or as a substitute for ev3’s financial results prepared in accordance with GAAP. Some of the limitations associated with ev3’s use of these non-GAAP financial measures are as follows:

	•		Items such as amortization expense, stock-based compensation, and contingent consideration do not directly affect ev3’s cash flow position; however, such items reflect economic costs to ev3 and are not reflected in ev3’s “non-GAAP adjusted net income” or “non-GAAP adjusted net earnings per share,” and therefore these non-GAAP measures do not reflect the full economic effect of these items.
	•		Items such as the FoxHollow lease reserve adjustment and realized gain on the divestiture of non-strategic investment assets are items that do not reflect ev3’s ongoing business activities. The effect of these items is not included in ev3’s “non-GAAP adjusted net income” or “non-GAAP adjusted net earnings per share.” However, these items involve economic costs that are not reflected in the non-GAAP measures.
	•		Non-GAAP financial measures are not based on any comprehensive set of accounting rules or principles and therefore other companies may calculate similarly titled non-GAAP financial measures differently than ev3, limiting the usefulness of those measures for comparative purposes.
	•		ev3’s management exercises judgment in determining which types of charges or other items should be excluded from the non-GAAP financial measures ev3 uses.

ev3 compensates for these limitations by relying primarily upon its GAAP results and only using non-GAAP financial measures on a supplemental basis. ev3 provides full disclosure of each non-GAAP financial measure ev3 uses and detailed reconciliations of each non-GAAP measure to its most directly comparable GAAP measure. ev3 encourages investors to review these reconciliations. ev3 qualifies its use of non-GAAP financial measures with cautionary statements as to their limitations.
