LeMaitre Vascular Q3 2010 Sales $13.7mm (+6% Organic) & Record Op. Income $2.0mm

BURLINGTON, MA, October 28, 2010 — LeMaitre Vascular, Inc. (NASDAQ: LMAT), a provider of peripheral vascular devices and implants, today announced Q3 2010 financial results. The Company posted sales of $13.7mm, a 76.1% gross margin and record operating income of $2.0mm. The Company increased its Q4 and full-year 2010 top- and bottom-line guidance. Separately, the Company announced the upcoming transfer of its polyester graft production to Burlington.

Q3 2010 sales increased 6% on an organic basis and 2% as reported, versus Q3 2009. Vascular was up 15% organically, General Surgery increased 8% and Endovascular was down 13%. On a reported basis, Vascular was up 12%, General Surgery increased 1% and Endovascular was down 18%. Vascular accounted for 73% of sales, benefiting from strong valvulotome growth, higher ASPs and a larger domestic sales force.

The Company reported a 76.1% gross margin in Q3 2010, up from 73.0% in Q3 2009. This increase was driven by manufacturing efficiencies, higher ASPs and a favorable mix (65% of Q3 2010 sales were in the Americas versus 58% in the prior year quarter).

Q3 2010 operating income was a record $2.0mm versus $1.3mm in Q3 2009, resulting in a record 15% operating margin. Q3 2010 net income was a record $1.5mm or $0.09 per diluted share, versus $1.3mm, or $0.08 per diluted share in Q3 2009.

At September 30, 2010 cash and marketable securities totaled $27.6mm. Excluding share repurchases, the Company’s cash increased by $2.1mm during Q3 2010, the result of $1.5mm in net income and $0.6mm of depreciation, amortization and stock-based compensation.

George W. LeMaitre, Chairman & CEO said, “Our record profits and operating margin were driven by a post-IPO record gross margin and tight expense control. In fact, operating expenses decreased 1% versus Q3 2009. Separately, we have been working on two initiatives which I believe will cut costs, improve strategic focus and increase our growth rate. First, we will be closing our Brindisi, Italy factory and transferring our vascular graft production to Burlington. Centralizing production should reduce costs significantly. Second, in order to focus on our higher growth vascular business, we will be limiting investments in our TAArget and UniFit stent-graft program, including suspension of the two U.S. trials.”

Sales and marketing expenses increased 4% in Q3 2010 to $4.7mm. The spending increase was driven by a larger sales force and increased commissions. The Company ended Q3 2010 with 63 sales reps versus 56 at the end of Q3 2009.

General and administrative expenses in Q3 2010 were $2.5mm, a 2% increase over the year-earlier quarter.

Q3 2010 research and development expenses decreased 22% to $1.1mm, primarily driven by lower regulatory and clinical spending, as well as reduced royalties. Additionally, the Company has elected to redeploy approximately $1.0mm which it spends annually on TAArget & UniFit R&D.

Brindisi Production Transfer

On October 27th, the Company’s Board approved the closure of its’ Brindisi factory and production transfer to Burlington. This is the Company’s sixth factory closure since 2002. The closure is anticipated to take place in December, 2010. The Brindisi employees went on strike October 4, returned to work October 20, 2010, and have agreed to work while separation terms are negotiated. During the nine months ending September 30, 2010, 4% of the Company’s revenues were derived from Brindisi-manufactured products. The Company currently expects non-severance charges of approximately $1.8mm. It is unclear when these non-severance charges will be recorded. Also, the Company cannot currently estimate severance charges. Due to the uncertainty of the timing and the amounts, no exit-related charges have been included in the Q4 and 2010 guidance given below. The Company expects this closure to increase operating income by approximately $1.0mm per year in 2012 and beyond.

Share Repurchase

During Q3 2010 the Company spent $383,000 to repurchase 59,409 shares of its common stock at an average price of $6.45 per share. The Company’s Board has authorized up to $5mm of its common stock to be purchased from time to time in the open market or in privately negotiated transactions. Since the program began in August 2009, $1.9mm of shares have been repurchased. Repurchases may be made under a Rule 10b5-1 plan, which permit shares to be repurchased when the Company might otherwise be precluded from doing so under insider trading laws. The repurchase program may be suspended or discontinued at any time and will conclude no later than December 31, 2011, unless extended by the Company’s Board. The program is funded by the Company’s cash and cash equivalents.

Q4 2010 Business Outlook

The Company increased its full-year 2010 sales guidance to $55.9mm, which implies 12% organic growth versus 2009. The Company increased its Q4 2010 sales guidance to $14.3mm which implies 9% organic growth versus Q4 2009. The Company increased its full-year 2010 operating income guidance to $6.9mm, and its Q4 2010 operating income guidance to $1.6mm. Operating income guidance amountsexcludecharges related to the Brindisi production transfer. Guidance amounts also exclude the effects of additional restructurings, acquisitions, foreign exchange fluctuations and distributor terminations.

Use of Non-GAAP Financial Measures

LeMaitre Vascular management believes that in order to properly understand the Company’s short-term and long-term financial trends, investors may wish to consider the impact of certain non-cash or non-recurring items, when used as a supplement to financial performance measures in accordance with GAAP. These items result from facts and circumstances that vary in frequency and/or impact on continuing operations. In addition, management uses results of operations before such items to evaluate the operational performance of the Company and as a

Page 3

basis for strategic planning. Investors should consider these non-GAAP measures in addition to, and not as a substitute for, financial performance measures in accordance with GAAP. In addition to the description provided below, reconciliation of GAAP to non-GAAP results is provided in the financial statement tables included in this press release.

This press release includes sales growth after adjusting for foreign exchange, business development transactions, and other non-recurring events. The Company refers to this as “organic” sales growth. The Company analyzes net sales on a constant currency basis net of acquisitions and other non-recurring events to better measure the comparability of results between periods. Because changes in foreign currency exchange rates have a non-operating impact on net sales, and acquisitions, product discontinuations, and other strategic transactions are episodic in nature and highly variable in sales impact, the Company believes that evaluating growth in sales on a constant currency basis net of such transactions provides an additional and meaningful assessment of sales to both management and the Company’s investors. During Q2 2010, the Company divested the OptiLock Implantable Port and discontinued sales of the aSpire Stent.

This press release also includes increase in cash and marketable securities net of the Company’s share repurchase program. The Company analyzes changes in cash and marketable securities net of its share repurchase program in order to better measure the cash being produced by the Company’s business and operations as regularly conducted. Because its share repurchase program is a temporary and discretionary program highly dependent on market factors outside of the Company’s control such as the price and liquidity of the Company’s common stock, the Company believes that evaluating changes in cash and marketable securities net of its share repurchase program provides an additional and meaningful assessment to both management and the Company’s investors.
