EXPLANATORY NOTE

We are filing this Amendment No. 2 (the Amendment No. 2) to our Annual Report on Form 10-K for the year ended December 31, 2016 originally filed
with the U.S, Securities and Exchange Commission on March 9, 2017 (the Original Form 10-K). We had previously amended the Original Form 10-K on January 12, 2018 for the purpose of correcting disclosures provided in Item 9A. Controls and
Procedures, which inadvertently omitted the conclusions of our principal executive and financial officers regarding the effectiveness of our disclosure controls and procedures. However, in that amended filing we did not include the Report of
Independent Registered Public Accounting Firm (the Report) as required under Item 9A. In this Amendment No. 2 we have included the Report.

This Amendment No. 2 includes only Item 9A. Controls and Procedures, the Exhibit Index in Part IV, Item 15 and Exhibits 31 and 32 of the Original Form 10-K.
Those sections of the Original Form 10-K that are unaffected by this Amendment No. 2 are not included herein. This Amendment No. 2 continues to speak as of the date of the Original Form 10-K. Furthermore, this Amendment No. 2 does not reflect events
occurring after the date of the Original Form 10-K.

PART I



|Item 9A. | Controls and Procedures
|-------- | -----------------------

Evaluation of Disclosure Controls and Procedures

Our management, with the participation and supervision of our Chief Executive Officer and Chief Financial Officer, is responsible for our
disclosure controls and procedures pursuant to Rules 13a-15(e) and 15d-15(e) under the Exchange Act. Disclosure controls and procedures are controls and other procedures
that are designed to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified under SEC rules and forms. Disclosure
controls and procedures include controls and procedures designed to ensure that information required to be disclosed in our reports filed under the Exchange Act is accumulated and communicated to our principal executive officer and our principal
financial officer, as appropriate, to allow timely decisions regarding required disclosure. We design our disclosure controls and procedures to ensure, at reasonable assurance levels, that such information is timely recorded, processed, summarized
and reported, and then accumulated and communicated appropriately.

Based on an evaluation of our disclosure controls and procedures as of
December 31, 2016, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective at reasonable assurance levels.

Managements Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) to provide reasonable assurance regarding the reliability of our financial reporting and the preparation of
financial statements for external purposes in accordance with GAAP.

Management assessed the effectiveness of our internal controls over
financial reporting as of December 31, 2016. Management based its assessment on criteria established in the Internal Control Integrated Frameworkissued by the Committee of Sponsoring Organizations of the
Treadway Commission (2013 Framework). Managements assessment included evaluation of elements such as the design and operating effectiveness of key financial reporting controls, process documentation, accounting policies, and our overall
control environment. In November 2016, we acquired substantially all of the assets of the RestoreFlow allograft business from Restore Flow Allografts LLC. This acquired business, which during 2016 comprised 0.6% of our revenues and as of
December 31, 2016 comprised 3.3% of our total assets, is excluded from our report on internal control over financial reporting.

Based on this assessment under the criteria set forth in the Internal Control Integrated Framework,
management has concluded that our internal control over financial reporting was effective as of December 31, 2016.

Our internal
control over financial reporting as of December 31, 2016 has been audited by Grant Thornton LLP, an independent registered public accounting firm, as stated in their respective report which is included herein.

Remediation of Prior Year Material Weakness

The material weakness that was previously disclosed as of December 31, 2015 was remediated as of December 31, 2016. See
Managements Report on Internal Control over Financial Reporting above. As disclosed in the quarterly reports on Form 10-Q for the first three quarters of 2016, the Company has implemented and
executed the Companys remediation plans, and as of December 31, 2016, such remediation plans were successfully tested and the material weakness was deemed remediated.

Changes in Internal Control over Financial Reporting

Except for the acquisition of the RestoreFlow allograft business noted above under Managements Report on Internal Control Over
Financial Reporting, there was no change in our internal control over financial reporting that occurred during the fiscal quarter ended December 31, 2016, that has materially affected, or is reasonably likely to materially affect our
internal control over financial reporting. Management is in the process of assessing the effectiveness of internal control over financial reporting for the acquired business.

Inherent Limitations of Internal Controls

Notwithstanding the foregoing, 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 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 also is 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, 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.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Shareholders

LeMaitre Vascular, Inc.

We have audited the internal control over financial reporting of LeMaitre Vascular, Inc. (a Delaware corporation) and subsidiaries (the
Company) as of December 31, 2016, based on criteria established in the 2013 Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Companys
management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Managements Report on
Internal Control Over Financial Reporting, (Managements Report). Our responsibility is to express an opinion on the Companys internal control over financial reporting based on our audit. Our audit of, and opinion on,
the Companys internal control over financial reporting does not include the internal control over financial reporting of the RestoreFlow allograft business, whose financial statements reflect total assets and revenues constituting 3.3 percent
and 0.6 percent, respectively, of the related consolidated financial statement amounts as of and for the year ended December 31, 2016. As indicated in Managements Report, the RestoreFlow allograft business was acquired during the fourth
quarter of 2016. Managements assertion on the effectiveness of the Companys internal control over financial reporting excluded internal control over financial reporting of the RestoreFlow allograft business.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial
reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the
circumstances. We believe that our audit provides a reasonable basis for our opinion.

A companys internal control over financial reporting is a
process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A companys
internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company;
(2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made
only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the companys assets that could
have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or
detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or
procedures may deteriorate.

In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of
December 31, 2016, based on criteria established in the 2013 Internal Control — Integrated Framework issued by COSO.

We also have audited, in
accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements of the Company as of and for the year ended December 31, 2016, and our report dated March 8, 2017 expressed an
unqualified opinion on those financial statements.
