We develop, manufacture, and market medical devices and implants used primarily in the field of vascular surgery. We operate in a single segment in which our principal product lines include the following: valvulotomes, balloon catheters, carotid shunts, biologic patches, biologic grafts, radiopaque marking tape, anastomotic clips, remote endarterectomy devices, laparoscopic cholecystectomy devices, vascular grafts, angioscopes, and powered phlebectomy devices. Our offices are located in Burlington, Massachusetts; Mississauga, Canada; Sulzbach, Germany; Milan, Italy; Madrid, Spain; North Melbourne, Australia; Tokyo, Japan; and Shanghai, China.

Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (GAAP) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments, consisting only of normal, recurring adjustments considered necessary for a fair presentation of the results of these interim periods have been included. Preparing financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. Actual results may differ from these estimates. Our estimates and assumptions, including those related to bad debts, inventories, intangible assets, sales returns and discounts, share-based compensation, and income taxes are updated as appropriate. The results for the three months ended March 31, 2015 are not necessarily indicative of results to be expected for the entire year. The information contained in these interim financial statements should be read in conjunction with our audited consolidated financial statements as of and for the year ended December 31, 2014, including the notes thereto, included in our Form 10-K filed with the Securities and Exchange Commission (SEC).

Consolidation

Our consolidated financial statements include the accounts of LeMaitre Vascular and the accounts of our wholly-owned subsidiaries, LeMaitre Vascular GmbH, LeMaitre Vascular GK, Vascutech Acquisition LLC, LeMaitre Acquisition LLC, LeMaitre Vascular SAS, LeMaitre Vascular S.r.l., LeMaitre Vascular Spain SL, LeMaitre Vascular Switzerland GmbH, LeMaitre Vascular ULC, LeMaitre Vascular AS, LeMaitre Vascular Pty Ltd, Xenotis Pty Ltd, and LeMaitre Medical Technology (Shanghai) Co., Ltd. All significant intercompany accounts and transactions have been eliminated in consolidation.

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board issued a new accounting standard that provides for a comprehensive model to use in the accounting for revenue arising from contracts with customers that will replace most existing revenue recognition guidance in GAAP. Under this standard, revenue will be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. This standard will be effective for annual reporting periods beginning after December 15, 2016, allows for either full retrospective or modified retrospective application, and early adoption is not permitted. We are assessing the new standard and which adoption method we will apply. We have not yet determined the impact on our results of operations.

Table of Contents

As part of the process of preparing our consolidated financial statements we are required to determine our income taxes in each of the jurisdictions in which we operate. This process involves estimating our actual current tax expense together with assessing temporary differences resulting from recognition of items for income tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included within our consolidated balance sheet. We must then assess the likelihood that our deferred tax assets will be recovered from taxable income during the carryback period or in the future; and to the extent we believe that recovery is not more likely than not, we must establish a valuation allowance. To the extent we establish a valuation allowance or increase this allowance in a period, we must reflect this increase as an expense within the tax provision in the statement of operations. We do not provide for income taxes on undistributed earnings of foreign subsidiaries, as our intention is to permanently reinvest these earnings.

We recognize, measure, present and disclose in our financial statements any uncertain tax positions that we have taken, or expect to take on a tax return. We operate in multiple taxing jurisdictions, both within and without the United States, and may be subject to audits from various tax authorities. Management’s judgment is required in determining our provision for income taxes, our deferred tax assets and liabilities, liabilities for uncertain tax positions, and any valuation allowance recorded against our net deferred tax assets. We will monitor the realizability of our deferred tax assets and adjust the valuation allowance accordingly.

Our policy is to classify interest and penalties related to unrecognized tax benefits as income tax expense.

Our 2015 income tax expense varies from the statutory rate mainly due to certain permanent items, offset by lower statutory rates from a mix of our foreign entities. Our 2014 income tax expense varies from the statutory rate mainly due to certain permanent items, a discrete item related to a provision to return benefit, lower statutory rates from a mix of our foreign entities and establishing an uncertain tax position reserve.

We have reviewed the tax positions taken, or to be taken, in our tax returns for all tax years currently open to examination by a taxing authority. As of March 31, 2015, the gross amount of unrecognized tax benefits exclusive of interest and penalties was $72,000. We remain subject to examination until the statute of limitations expires for each respective tax jurisdiction. The statute of limitations will be open with respect to these tax positions until 2024. A reconciliation of beginning and ending amount of our unrecognized tax benefits is as follows:

As of March 31, 2015, a summary of the tax years that remain subject to examination in our taxing jurisdictions is as follows:

Inventories consist of the following:

We held inventory on consignment of $0.8 million as of March 31, 2015 and December 31, 2014.

Clinical Instruments International, Inc.

In July 2013, we entered into an asset purchase agreement with Clinical Instruments International, Inc. (Clinical Instruments) to acquire substantially all the assets of Clinical Instruments for $1.1 million. We paid $0.9 million at the closing and paid the remaining $0.2 million in October 2014. We accounted for the acquisition as a business combination. Assets acquired include inventory and intellectual property. We recorded $0.2 million of inventory, $0.3 million of intangible assets and $0.6 million of goodwill. The weighted-average amortization period for the acquired intangible assets as of July 31, 2013 was 5.7 years. The goodwill will be deductible for tax purposes over 15 years.

InaVein LLC

In August 2013, we entered into an asset purchase agreement with InaVein LLC (InaVein) to acquire substantially all the assets of InaVein for $2.5 million and potential acquisition-related contingent consideration totaling up to $1.4 million in 2014 and 2015 dependent on the sales performance of the acquired business and the timing of regulatory approval in China. We paid $2.1 million at the closing and paid the remaining $0.4 million in September 2014. We accounted for the acquisition as a business combination. Assets acquired include receivables, inventory, equipment, and intellectual property. Liabilities assumed include payables and service contracts. We recorded $0.8 million of tangible assets, $1.1 million of intangible assets, $0.7 million of goodwill, and $0.1 million of assumed liabilities. The weighted-average amortization period for the acquired intangible assets as of August 31, 2013 was 6.7 years. The goodwill will be deductible for tax purposes over 15 years.

The contingent consideration was initially valued at the date of acquisition and is remeasured each reporting period until the contingency is resolved. Based upon stronger than expected sales to China, we recorded an increase of $0.1 million in the contingent consideration dependent on the sales performance of the acquired business in the first year following the closing as a charge to general and administrative expense in 2014. In October 2014, we paid $0.2 million for the first sales related milestone. The milestone related to the timing of the regulatory approval in China was not achieved. The final potential milestone payment is dependent on sales performance of the acquired business from August 2014 to August 2015. We currently do not expect to pay the second sales related milestone.

Xenotis Pty Ltd

In August 2014, we entered into a stock purchase agreement with the shareholders of Xenotis Pty Ltd (Xenotis) to acquire all of the capital stock of Xenotis for $6.7 million with a mechanism for a purchase price adjustment based on the net tangible assets of Xenotis at closing. Xenotis is the parent company of Bio Nova International, the manufacturer and marketer of the Omniflow II biosynthetic vascular graft for lower extremity bypass and AV access. We paid $5.1 million at the closing and the remaining $1.4 million is payable in August 2015. The net tangible asset purchase price adjustment of $0.2 million was paid in November 2014. We accounted

Table of Contents

for the acquisition as a business combination. Assets acquired include receivables, inventory, equipment, a building, and intellectual property. We recorded $2.1 million of tangible assets, $2.1 million of property and equipment, $1.8 million of intangible assets, and $2.5 million of goodwill. The weighted-average amortization period for the acquired intangible assets as of August 31, 2014 was 6.8 years. Liabilities assumed include payables and debt which totaled $1.7 million and included $1.1 million of assumed debt, which we paid in full in August 2014. The purchase accounting is complete.

The goodwill of $2.5 million will not be deductible for tax purposes. In addition, we acquired deferred tax assets of $2.4 million which consist primarily of net operating loss carry-forwards and capital loss carry-forwards. We recorded a full valuation allowance on these deferred tax assets.

In September 2014, we entered into definitive agreements with eight former Xenotis distributors in Europe to terminate their distribution of our Omniflow II biosynthetic vascular grafts for $1.3 million. We paid approximately $1.1 million in 2014 and $0.2 million in 2015 with the remaining $20,000 due in 2015. We recorded $0.4 million of inventory and $0.9 million of intangible assets. We allocated the payment to the tangible and intangible assets acquired based on the estimated fair value of each of these elements to the transactions. The weighted-average amortization period for the acquired intangible assets as of September 30, 2014 was 5.0 years.

Angioscope

In September 2014, we entered into an asset purchase agreement with Applied Medical Resource Corporation (Applied Medical) to acquire substantially all the assets related to Applied Medical’s angioscope product line for $0.4 million. We paid $0.3 million at closing and the remaining $0.1 million is payable in December 2015. We accounted for the acquisition as a business combination. Assets acquired include inventory, property and equipment, and intellectual property. We recorded $0.1 million of tangible assets, $0.3 million of intangible assets, and $0.1 million of goodwill. The weighted-average amortization period for the acquired intangible assets as of September 30, 2014 was 7.5 years. The goodwill will be deductible for tax purposes over 15 years. The purchase accounting is complete.

Our acquisitions have historically been made at prices above the fair value of the acquired identifiable assets, resulting in goodwill, due to expectations of synergies that will be realized by combining businesses. These synergies include the use of our existing sales channel to expand sales of the acquired businesses’ products, consolidation of manufacturing facilities, and the leveraging of our existing administrative infrastructure.

The fair market valuations associated with these transactions fall within Level 3 of the fair value hierarchy, due to the use of significant unobservable inputs to determine fair value. The fair value measurements were calculated using unobservable inputs, primarily using the income approach, specifically the discounted cash flow method. The amount and timing of future cash flows within our analysis was based on our due diligence models, most recent operational budgets, long range strategic plans and other estimates.

Goodwill consists of the following:

Other intangibles consist of the following:

These intangible assets are being amortized over their useful lives ranging from 1 to 13 years. The weighted-average amortization period for these intangibles as of March 31, 2015 is 6.7 years. Amortization expense is included in general and administrative expense and is as follows:

Estimated amortization expense for the remainder of 2015 and each of the five succeeding fiscal years is as follows:

Accrued expenses consist of the following:

Table of Contents

In February 2014, we committed to a plan intended to improve operational efficiencies, which included a reduction in force of approximately 10% of our workforce and other cost-cutting measures, including the transfer of our Clinical Instruments manufacturing to our Burlington headquarters and corresponding closure of our Southbridge manufacturing facility. As a result, we recorded approximately $0.4 million of severance related restructuring expense for the three months ended March 31, 2014. We made approximately $0.1 million of severance related payments during the three months ended March 31, 2014.

In April 2014, we committed to an additional reduction in force of approximately seven employees. As a result, we recorded approximately $0.1 million of severance related restructuring expense for the three months ended June 30, 2014.

We did not incur restructuring charges during the three months ended March 31, 2015.

Purchase Commitments

As of March 31, 2015, as part of our normal course of business, we have purchase commitments to purchase $4.7 million of inventory through 2016.

The FASB establishes standards for reporting information regarding operating segments in financial statements. Operating segments are identified as components of an enterprise about which separate, discrete financial information is evaluated by the chief operating decision-maker in making decisions on how to allocate resources and assess performance. We view our operations and manage our business as one operating segment. No discrete operating information is prepared by us except for product sales by product line and by legal entity for local reporting purposes.

Most of our revenues were generated in the United States, Germany, Italy, Japan, Canada, and other European countries, and substantially all of our assets are located in the United States. Net sales to unaffiliated customers by country were as follows:

Our 2006 Stock Option and Incentive Plan allows for granting of incentive stock options, non-qualified stock options, stock appreciation rights, restricted stock units, unrestricted stock awards, and deferred stock awards to our officers, employees, directors, and consultants.

The components of share-based compensation expense were as follows:

We did not issue option grants in the three months ended March 31, 2015 and 2014. The weighted-average fair value per share of restricted stock unit grants issued for the three months ended March 31, 2015 was $7.42. We did not issue restricted stock unit grants in the three months ended March 31, 2014.

We issued approximately 140,000 and 23,000 shares of common stock following the exercise or vesting of underlying stock options or restricted stock units in the three months ended March 31, 2015 and 2014, respectively.

The computation of basic and diluted net income per share was as follows:

Share Offering

On June 4, 2014, we issued 1,644,500 shares of our common stock, $0.01 par value per share, at a price to the public of $7.00 per share less underwriting discounts. The net proceeds, after deducting the underwriting discounts and other estimated offering expenses, were approximately $10.5 million. We have deployed the net proceeds from the offering on acquisitions consummated in 2014 and used the remainder for general corporate purposes, including continued development of our products, working capital and capital expenditures, payments under our quarterly dividend program, payments related to acquisitions.

Dividends

In February 2011, our Board of Directors approved a policy for the payment of quarterly cash dividends on our common stock. Future declarations of quarterly dividends and the establishment of future record and payment dates are subject to approval by our Board of Directors on a quarterly basis. The dividend activity for the periods presented is as follows:

We funded the dividend on March 31, 2015 which was then distributed to shareholders on April 3, 2015.

On April 23, 2015 our Board of Directors approved a quarterly cash dividend on our common stock of $0.04 per share payable on June 5, 2015 to stockholders of record at the close of business on May 22, 2015, which will total approximately $0.7 million.

The fair value accounting guidance requires that assets and liabilities carried at fair value be classified and disclosed in one of the following three categories:

As of March 31, 2015, we had cash equivalents in a money market fund that was valued using Level 1 inputs (quoted market prices for identical assets) at a fair value of $10.0 million.

14

Table of Contents

We had no Level 2 assets being measured at fair value on a recurring basis as of March 31, 2015.

As discussed in Note 4, we have one remaining acquisition-related contingent liability which is remeasured each reporting period using Level 3 techniques based on an assessment of the probability that we will be required to make such future payment. There were no changes in estimated liability associated with this milestone as we currently do not expect to pay the second sales related milestone.

Changes to our accumulated other comprehensive loss consisted of foreign currency translation for the three months ended March 31, 2015 and 2014, respectively.

This Quarterly Report on Form 10-Q contains forward-looking statements (within the meaning of the federal securities law) that involve substantial risks and uncertainties. All statements, other than statements of historical facts, included in this report regarding our strategy, future operations, future financial position, future net sales, projected costs, projected expenses, prospects and plans and objectives of management are forward-looking statements. The words “anticipates,” “believes,” “estimates,” “expects,” “intends,” “may,” “plans,” “projects,” “will,” “would,” and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words. We have based these forward-looking statements on our current expectations and projections about future events. Although we believe that the expectations underlying any of our forward-looking statements are reasonable, these expectations may prove to be incorrect, and all of these statements are subject to risks and uncertainties. Should one or more of these risks and uncertainties materialize, or should underlying assumptions, projections, or expectations prove incorrect, our actual results, performance, or financial condition may vary materially and adversely from those anticipated, estimated, or expected. These risks and uncertainties include, but are not limited to: the risk that the Company may not realize the anticipated benefits of its strategic activities; risks related to the integration of acquisition targets; the risk that assumptions about the market for the Company’s products and the productivity of the Company’s direct sales force and distributors may not be correct; risks related to product demand and market acceptance of the Company’s products; the risk that the XenoSure product is not as accretive and does not achieve the gross margins currently anticipated by the Company; the risk that the Company experiences increased expense, production delays or quality difficulties in increasing the production of our XenoSure manufacturing operations; risks related to attracting, training and retaining sales representatives and other employees in new markets such as Australia and Norway; and the risk that the Company is not successful in transitioning to a direct-selling model in new territories.

Forward-looking statements reflect management’s analysis as of the date of this quarterly report. Further information on potential risk factors that could affect our business and financial results is detailed in Part II, Item 1A, “Risk Factors” in this Quarterly Report on Form 10-Q and in our other filings with the Securities and Exchange Commission, including under the section headed “Risk Factors” in our most recent Annual Report on Form 10-K. Given these risks, uncertainties and other factors, you should not place undue reliance on these forward-looking statements. The following discussion and analysis should be read in conjunction with our consolidated financial statements and the related notes included in this report and our other SEC filings, including our audited consolidated financial statements and the related notes contained in our Annual Report on Form 10-K for the year ended December 31, 2014, as filed with the SEC on March 18, 2015. We do not assume any obligation to update any forward-looking statements, whether as a result of new information, future events, or otherwise, except as required by law.

Overview

We are a medical device company that develops, manufactures, and markets medical devices and implants for the treatment of peripheral vascular disease. Our principal product offerings are sold throughout the world, primarily in the United States, Europe and, to a lesser extent, Asia and the Pacific Rim. We estimate that the annual worldwide market for all peripheral vascular devices approximates $4 billion, within which our core product lines address roughly $750 million. We have grown our business by using a three-pronged strategy: competing for sales of niche products, expanding our worldwide direct sales force, and acquiring and developing complementary vascular devices. We have used acquisitions as a primary means of further accessing the larger peripheral vascular device market, and we expect to continue to pursue this strategy in the future. Additionally, we have increased our efforts to expand our vascular device offerings through new product development. We currently manufacture most of our product lines in our Burlington, Massachusetts, headquarters.

16

Table of Contents

Our products are used by vascular surgeons who treat peripheral vascular disease through both open surgical methods and endovascular techniques. In contrast to interventional cardiologists and interventional radiologists, neither of whom are certified to perform open surgical procedures, vascular surgeons can perform both open surgical and minimally invasive endovascular procedures, and are therefore uniquely positioned to provide a wider range of treatment options to patients.

Our principal product lines include the following: valvulotomes, balloon catheters, carotid shunts, biologic vascular patches, radiopaque marking tape, anastomotic clips, remote endarterectomy devices, laparoscopic cholecystectomy devices, vascular grafts, biosynthetic vascular grafts, angioscopes, and powered phlebectomy devices.

To assist us in evaluating our business strategies, we regularly monitor long-term technology trends in the peripheral vascular device market. Additionally, we consider the information obtained from discussions with the medical community in connection with the demand for our products, including potential new product launches. We also use this information to help determine our competitive position in the peripheral vascular device market and our manufacturing capacity requirements.

Our business opportunities include the following:

We sell our products primarily through a direct sales force. As of March 31, 2015 our sales force was comprised of 81 sales representatives in North America, Europe, Japan, and Australia. We also sell our products in other countries through distributors. Our worldwide headquarters is located in Burlington, Massachusetts. Our international operations are headquartered in Sulzbach, Germany. We also have sales offices located in Tokyo, Japan; Mississauga, Canada; Madrid, Spain; Milan, Italy; Shanghai, China; and North Melbourne, Australia. In the three months ended March 31, 2015, approximately 93% of our net sales were generated in territories in which we employ direct sales representatives.

We have experienced success in niche product segments, for example the market segments for biologic patches and valvulotome devices. In the biologic patch market segment, we believe that we have been able to increase segment share and increase selling prices. In the valvulotome market segment, we believe that we have been able to increase selling prices without compromising market segment share. There can be no assurance that we will not meet resistance to increased selling prices in the future. In contrast, we have experienced less success in highly competitive product segments such as polyester and ePTFE grafts, where we face stronger competition from larger companies with greater resources. We have also experienced less success in segments such as radiopaque tape, where we face recently introduced competitive products. While we believe that these challenging market dynamics can be mitigated by our strong relationships with our vascular surgeon customers, there can be no assurance that we will be successful in highly competitive market segments.

In recent years we have also experienced comparatively greater success in geographic markets outside of the United States, including Europe and other non-traditional markets for our devices such as China and Saudi Arabia. Sales to these geographies generally include comparatively lower average selling prices, and to the extent that we continue to be successful in these markets, as well as successful at selling our biologic vascular patch device which carries a lower margin, we will likely experience downward pressure on our gross margin.

17

Table of Contents

Because we believe that direct-to-hospital sales engender closer customer relationships, and allow for higher selling prices and gross margins, we periodically enter into transactions with our distributors to transition their sales of our medical devices to our direct sales organization:

We anticipate that the expansion of our direct sales organization in Australia and our sales office in China will result in increased sales and marketing expenses during 2015.

Our strategy for growing our business includes the acquisition of complementary product lines and companies and occasionally the discontinuance or divestiture of products or activities that are no longer complementary:

In addition to relying upon acquisitions to grow our business, we also rely on our product development efforts to bring differentiated technology and next-generation products to market. These efforts have led to the following recent product developments:

In addition to our sales growth strategies, we have also executed several operational initiatives designed to consolidate and streamline manufacturing within our Burlington, Massachusetts facilities. We expect that these plant consolidations will result in improved control over our production capacity as well as reduced costs over the long-term. Our most recent manufacturing transitions included:

18

Table of Contents

We currently expect to maintain the manufacturing operations of the recently acquired North Melbourne, Australia facility for the foreseeable future.

Our execution of these business opportunities may affect the comparability of our financial results from period to period and may cause substantial fluctuations from period to period, as we incur related restructuring and other non-recurring charges, as well as longer term impacts to revenues and operating expenditures. For example, in 2014, we incurred $0.5 million of restructuring charges related to reductions in force and our Clinical Instruments facility closure and relocation to Burlington, Massachusetts.

Fluctuations in the rate of exchange between the U.S. dollar and foreign currencies, primarily the Euro, affect our financial results. For the three months ended March 31, 2015, approximately 39% of our sales were from outside the Americas. We expect that foreign currencies will continue to represent a similarly significant percentage of our sales in the future. Selling, marketing, and administrative costs related to these sales are largely denominated in the same respective currency, thereby partially mitigating our transaction risk exposure. However, most of our foreign sales are denominated in local currency, and if there is an increase in the rate at which a foreign currency is exchanged for U.S. dollars, it will require more of the foreign currency to equal a specified amount of U.S. dollars than before the rate increase. In such cases we will receive less in U.S. dollars than we did before the rate increase went into effect. For the three months ended March 31, 2015, the negative effects of foreign exchange reduced sales by $1.5 million. As of April 28, 2015, we estimate that the strong U.S. dollar could decrease our 2015 revenues by approximately $5.1 million, reduce gross margin by 1.9%, and reduce operating income by approximately $2.5 million as compared to the exchange rates for the year ended December 31, 2014. However, the actual impact of fluctuations in exchange rates in 2015 may vary materially and adversely from these estimates.

Net Sales and Expense Components

The following is a description of the primary components of our net sales and expenses:

Net sales. We derive our net sales from the sale of our products, less discounts and returns. Net sales include the shipping and handling fees paid for by our customers. Most of our sales are generated by our direct sales force and are shipped and billed to hospitals or clinics throughout the world. In countries where we do not have a direct sales force, sales are primarily generated by shipments to distributors who, in turn, sell to hospitals and clinics. In those cases where our products are held on consignment at a hospital or clinic, we generate sales at the time the product is used in surgery rather than at shipment.

Cost of sales. We manufacture nearly all of the products that we sell. Our cost of sales consists primarily of manufacturing personnel, raw materials and components, depreciation of property and equipment, and other allocated manufacturing overhead, as well as freight expense we pay to ship products to customers.

Sales and marketing. Our sales and marketing expense consists primarily of salaries, commissions, stock based compensation, travel and entertainment, attendance at medical society meetings, training programs, advertising and product promotions, direct mail, and other marketing costs.

General and administrative. General and administrative expense consists primarily of executive, finance and human resource expense, stock based compensation, legal and accounting fees, information technology expense, intangible amortization expense, and insurance expense.

Research and development. Research and development expense includes costs associated with the design, development, testing, enhancement, and regulatory approval of our products, principally salaries, laboratory testing, and supply costs. It also includes costs associated with design and execution of clinical studies, regulatory submissions and costs to register, maintain, and defend our intellectual property, and royalty payments associated with licensed and acquired intellectual property.

Restructuring. Restructuring expense includes costs directly associated with distribution agreement termination expenses, severance and retention costs for terminated employees, factory relocation costs, and other expenses associated with restructuring our operations.

19

Table of Contents

Other income (expense). Other income (expense) primarily includes interest income and expense, foreign currency gains (losses), and other miscellaneous gains (losses).

Income tax expense. We are subject to federal and state income taxes for earnings generated in the United States, which include operating losses in certain foreign jurisdictions for certain years depending on tax elections made, and foreign taxes on earnings of our wholly-owned Canadian, German, and Italian subsidiaries. Our consolidated tax expense is affected by the mix of our taxable income (loss) in the United States and foreign subsidiaries, permanent items, discrete items, unrecognized tax benefits, and amortization of goodwill for U.S tax reporting purposes.

Results of Operations

Comparison of the three months ended March 31, 2015 to the three months ended March 31, 2014.

The following tables set forth, for the periods indicated, our results of operations, net sales by geography, and the change between the specified periods expressed as a percentage increase or decrease:

Net sales. Net sales increased 13% to $18.9 million for the three months ended March 31, 2015, compared to $16.8 million for the three months ended March 31, 2014. Sales increases for the three months ended March 31, 2015 were primarily driven by increased sales of our biologic vascular patches of $0.6 million, valvulotomes of $0.6 million, radiopaque tape of $0.2 million (driven by $0.3 million of OEM tape sales) and powered phlebectomy devices of $0.2 million, and were partially offset by decreased sales of cholangiogram catheters of $0.2 million, catheters of $0.2 million and the negative effects of foreign exchange of $1.5 million. Our biosynthetic vascular graft, acquired in August 2014, contributed $1.0 million of sales during the three months ended March 31, 2015.

Direct-to-hospital net sales were 93% for the three months ended March 31, 2015 and 2014.

Net sales by geography. Net sales in the Americas increased $1.2 million for the three months ended March 31, 2015. The increase was primarily driven by valvulotomes, biologic vascular patches, radiopaque tape, and vessel closure systems and was partially offset by decreased sales of cholangiogram catheters and catheters. International net sales increased $1.0 million for the three months ended March 31, 2015. The increase was primarily driven by our newly acquired biosynthetic vascular graft sales as well as increased sales in biologic vascular patches and valvulotomes. Recently, we have experienced stronger sales growth in Europe as well as other non-traditional markets such as China and Saudi Arabia as compared to the United States and Canada. This trend may continue through 2015.

Gross Profit. Gross profit increased $1.9 million to $13.1 million for the three months ended March 31, 2015, while gross margin increased 2.2% to 69.2% in the period. The gross margin increase was largely driven by the completion of the biologic vascular patch manufacturing transition in the second quarter of 2014 resulting in reduced manufacturing costs in the current year, other manufacturing efficiencies, and by higher average selling prices across all product lines. These increases were partially offset by the negative impact of foreign exchange on our international sales results and costs associated with our biologic vascular graft. The gross profit increase was a result of higher sales and the improved gross margin.

Sales and marketing. For the three months ended March 31, 2015, sales and marketing expense decreased 6% to $5.9 million. Selling expense decreased $0.3 million while marketing expense decreased $0.1 million. The decreases were driven by changes in foreign currency exchange rates of $0.5 million and were partly offset by increased compensation related costs. As a percentage of net sales, sales and marketing expense was 31% in the three months ended March 31, 2015. We plan to increase the size of our sales force in 2015, and we expect that selling and marketing expenses will increase commensurately.

General and administrative. For the three months ended March 31, 2015, general and administrative expense increased 9% to $3.6 million. The general and administrative expense increases were driven by increased professional services of $0.3 million and compensation related costs, and were partially offset by changes in foreign

currency exchange rates of $0.2 million. As a percentage of net sales, general and administrative expense was 19% in the three months ended March 31, 2015. We expect general and administrative expenses to increase in 2015 primarily due to our new subsidiary in China.

Research and development. For the three months ended March 31, 2015, research and development expense decreased 14% to $1.2 million. Product development expenses were relatively flat. Clinical and regulatory expenses decreased $0.1 million primarily due to costs related to regulatory submissions for new products in geographies such as China and Australia completed in the prior year period. As a percentage of net sales, research and development expense was 6% for the three months ended March 31, 2015.

Restructuring. In February 2014, we committed to a plan intended to improve operational efficiencies, which included a reduction in force of approximately 10% of our workforce and other cost-cutting measures, including the transfer of our recently acquired Clinical Instruments manufacturing to our Burlington headquarters and corresponding closure of our Southbridge manufacturing facility. As a result, we recorded approximately $0.4 million of severance related restructuring expense for the three months ended March 31, 2014. In April 2014, we committed to an additional reduction in force of approximately seven employees. As a result, we recorded approximately $0.1 million of severance related restructuring expense for the three months ended June 30, 2014. We did not incur restructuring charges during the three months ended March 31, 2015.

Medical device excise tax. The medical device excise tax was $0.2 million for the three months ended March 31, 2015 and 2014, respectively.

Income tax expense. We recorded a provision for taxes of $1.0 million on pre-tax income of $2.3 million for the three months ended March 31, 2015, compared to a benefit for taxes of $0.1 million on a pre-tax loss of $0.3 million for the three months ended March 31, 2014. Our 2015 provision was based on the estimated annual effective tax rate of 37.1%, comprised of estimated federal and state income taxes of approximately $3.1 million, as well as foreign income taxes of $0.4 million. Our income tax expense for the current period varies from the statutory rate amounts mainly due to certain permanent items, offset by lower statutory rates from our foreign entities. Our 2014 provision was based on the estimated annual effective tax rate of 37.2%, comprised of estimated federal and state income taxes of approximately $1.8 million, as well as foreign income taxes of $0.4 million. Our 2014 income tax expense varied from the statutory rate amounts mainly due to discrete item related to a provision to return benefit, establishing an uncertain tax provision reserve in Japan, lower statutory rates from our foreign entities, offset by certain permanent items. We monitor the mix of profitability by tax jurisdiction and adjust our annual expected rate on a quarterly basis as needed. While it is often difficult to predict the final outcome or timing of the resolution for any particular tax matter, we believe that our tax reserves reflect the probable outcome of known contingencies.

We have assessed the need for a valuation allowance against our deferred tax assets and concluded that as of March 31, 2015, we carry a valuation allowance against $3.2 million of deferred tax assets, principally foreign net operating loss and capital loss carry-forwards and state research and development credit carry-forwards, which based on the available evidence, we believe it is more likely than not that such assets will not be realized.

We expect that our effective tax rate to increase in 2015 if the Federal research and development tax credit is not reinstated in 2015. If the Federal research and development tax credit is reinstated in 2015, we expect our effective tax rate will be similar to our effective tax rate in 2014. We will not be able to generate Federal research and development tax credits in 2015 until and if legislation is enacted.

Liquidity and Capital Resources

At March 31, 2015, our cash and cash equivalents were $17.0 million as compared to $18.7 million at December 31, 2014. Our cash and cash equivalents are highly liquid investments with maturities of 90 days or less at the date of purchase, consist of money market funds, and are stated at cost, which approximates fair value. All of our cash held outside of the United States is available for corporate use.

Operating and Capital Expenditure Requirements

We require cash to pay our operating expenses, make capital expenditures, and pay our long-term liabilities. Since our inception, we have funded our operations through public offerings and private placements of equity securities, short-term borrowings, and funds generated from our operations.

We recognized operating income of $2.3 million for the three months ended March 31, 2015. For the year ended December 31, 2014, we recognized operating income of $6.3 million. We expect to fund any increased costs and expenditures from our existing cash and cash equivalents, though our future capital requirements depend on numerous factors. These factors include, but are not limited to, the following:

Our cash balances may decrease as we continue to use cash to fund our operations, make acquisitions, make payments under our quarterly dividend program, and make deferred payments related to prior acquisitions. We believe that our cash, cash equivalents, investments and the interest we earn on these balances will be sufficient to meet our anticipated cash requirements for at least the next twelve months. If these sources of cash are insufficient to satisfy our liquidity requirements beyond the next twelve months, we may seek to sell additional equity or debt securities or borrow funds from, or establish a revolving credit facility, with a financial institution. The sale of additional equity and debt securities may result in dilution to our stockholders. If we raise additional funds through the issuance of debt securities, such securities could have rights senior to those of our common stock and could contain covenants that would restrict our operations and possibly our ability to pay dividends. We may require additional capital beyond our currently forecasted amounts. Any such required additional capital may not be available on reasonable terms, if at all.

Share Offering

On June 4, 2014, we issued 1,644,500 shares of our common stock, $0.01 par value per share, at a price to the public of $7.00 per share less underwriting discounts. The net proceeds, after deducting the underwriting discounts and other estimated offering expenses, were approximately $10.5 million. We have deployed the net proceeds from the offering on acquisitions consummated in 2014 and used the remainder for general corporate purposes, including continued development of our products, working capital and capital expenditures, payments under our quarterly dividend program, payments related to acquisitions.

Dividends

In February 2011, our Board of Directors approved a policy for the payment of quarterly cash dividends on our common stock. Future declarations of quarterly dividends and the establishment of future record and payment dates are subject to approval by our Board of Directors on a quarterly basis. The dividend activity for the periods presented is as follows:

We funded the dividend on March 31, 2015 which was then distributed to shareholders on April 3, 2015.

On April 23, 2015 our Board of Directors approved a quarterly cash dividend on our common stock of $0.04 per share payable on June 5, 2015 to stockholders of record at the close of business on May 22, 2015, which will total approximately $0.7 million.

Cash Flows

Net cash used in operating activities. Net cash used in operating activities was $0.6 million for the three months ended March 31, 2015, and consisted of $1.4 million net income, adjusted for non-cash items of $1.4 million (including depreciation and amortization of $0.8 million, stock-based compensation of $0.3 million, and provision for inventory write-offs of $0.1 million) and was offset by changes in working capital of $3.3 million. The net cash used by changes in working capital was driven by increases in accounts receivable of $1.7 million and inventory of $0.4 million, and decreases in accounts payable and other liabilities of $1.3 million, primarily due to annual compensation payments.

Net cash used in operating activities was $1.7 million for the three months ended March 31, 2014, and consisted of a $0.2 million net loss, adjusted for non-cash items of $1.2 million (including depreciation and amortization of $0.8 million, stock-based compensation of $0.3 million, and provision for inventory write-offs of $0.1 million) and was offset by changes in working capital of $2.7 million. The net cash used by changes in working capital was driven by increases in inventory of $1.0 million, primarily related to powered phlebectomy devices, and decreases in accounts payable and other liabilities of $1.8 million, primarily due to annual compensation payments.

Net cash used in investing activities. Net cash used in investing activities was $0.5 million for three months ended March 31, 2015. This was driven by the purchase of property and equipment of $0.3 million and acquisition related payments of $0.1 million, primarily consisting of distributor termination payments associated with our recently acquired biologic vascular graft.

Net cash used in investing activities was $0.6 million for the three months ended March 31, 2014. This was primarily driven by the purchase of property and equipment of $0.4 million and distributor buyout payments of $0.2 million.

Net cash provided by financing activities. Net cash used in financing activities was $0.4 million for the three months ended March 31, 2015, driven primarily by payments of common stock dividends of $0.7 million and partially offset by proceeds from stock option exercises of $0.3 million.

Net cash provided by financing activities was $0.1 million for the three months ended March 31, 2014, driven primarily by proceeds from stock option exercises.

Contractual obligations. Our principal contractual obligations consist of operating leases and inventory purchase commitments. The following table summarizes our commitments to settle contractual obligations as of March 31, 2015:

The commitments under our operating leases consist primarily of lease payments for our Burlington, Massachusetts, corporate headquarters and manufacturing facility, expiring in 2023; our Mississauga, Canada office, expiring in 2018; our Sulzbach, Germany office, expiring in 2016; our Tokyo, Japan office, expiring in 2016; our Milan, Italy office, expiring in 2016; our Madrid, Spain office, expiring in 2017; our two North Melbourne, Australia facilities expiring in 2019; and our Shanghai, China office, expiring in 2016. They also include automobile and equipment leases.

The purchase commitments for inventory are intended to be used in operations in the normal course of business and do not represent excess commitments or loss contracts.

Off-Balance Sheet Arrangements

We did not have any off-balance sheet arrangements as of March 31, 2015. We do not currently have, nor have we ever had, any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. In addition, we do not engage in trading activities involving non-exchange traded contracts. As a result, we are not materially exposed to any financing, liquidity, market, or credit risk that could arise if we had engaged in these relationships.

Critical Accounting Policies and Estimates

We have adopted various accounting policies to prepare our consolidated financial statements in accordance with U.S. generally accepted accounting principles, or U.S. GAAP. Our most significant accounting policies are described in note 1 to our consolidated financial statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2014. There has been no material changes in our critical accounting policies during the three months ended March 31, 2015. The preparation of our consolidated financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the amounts reported in our consolidated financial statements and accompanying notes. Our estimates and assumptions, including those related to bad debts, inventories, intangible assets, sales returns and discounts, share-based compensation, and income taxes are reviewed on an ongoing basis and updated as appropriate. Actual results may differ from those estimates.

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board issued a new accounting standard that provides for a comprehensive model to use in the accounting for revenue arising from contracts with customers that will replace

25

Table of Contents

most existing revenue recognition guidance in GAAP. Under this standard, revenue will be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. This standard will be effective for annual reporting periods beginning after December 15, 2016, allows for either full retrospective or modified retrospective application, and early adoption is not permitted. We are assessing the new standard and which adoption method we will apply. We have not yet determined the impact on our results of operations.

Quantitative and Qualitative Disclosures About Market Risk

This item is not applicable to us as a smaller reporting company.

Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed by us in reports we file or submit under the Securities Exchange Act of 1934 is reported, processed, and summarized within the time periods specified in the SEC’s rules and forms. As of March 31, 2015, or the Evaluation Date, our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities and Exchange Act of 1934). Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of the Evaluation Date, our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Control

There have been no changes in our internal control over financial reporting for the quarter ended March 31, 2015, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations of Internal Controls

Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal controls will prevent all error and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. The design of any system of controls is also based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, a control may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

Part II. Other Information

In the ordinary course of business, we are from time to time involved in lawsuits, claims, investigations, proceedings, and threats of litigation relating to intellectual property, employment, product liability, commercial

arrangements and other matters. While the outcome of these proceedings and claims cannot be predicted with certainty, there are no matters, as of May 7, 2015, that management believes would have a material adverse effect on our financial position, results of operations or cash flows.

In addition to the information set forth in this report, you should consider the risks and uncertainties discussed in “Part I, Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2014, which could materially affect our business, financial condition, or future results. There have been no substantive changes from the risk factors previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2014, which was filed with the Securities and Exchange Commission on March 18, 2015.
