Dear Boston Scientific Stockholder:

You are cordially invited to attend the Annual Meeting of Stockholders of Boston Scientific Corporation (the Company) to be held on Tuesday, May 9, 2017, at 8:00 a.m. Eastern Time, at the Company's Corporate Headquarters located at 300 Boston Scientific Way, Marlborough, Massachusetts 01752 (Annual Meeting).

This year you are being asked to:

1.

elect to the Board of Directors ten nominees for director;



2.

approve, on a non-binding, advisory basis, named executive officer compensation;



3.

approve, on a non-binding, advisory basis, the frequency of future named executive officer compensation advisory votes;



4.

ratify the appointment of Ernst & Young LLP as our independent registered public accounting firm for the 2017 fiscal year; and



5.

consider and vote upon such other business as may properly come before the Annual Meeting or any adjournment or postponement thereof.

These matters are more fully described in the accompanying Notice of Annual Meeting and Proxy Statement. Our Board of Directors urges you to read the accompanying Proxy Statement and recommends that you vote "FOR" all of the director nominees, our named executive officer compensation, an annual frequency of holding a non-binding, advisory vote on named executive officer compensation, and the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm. At the meeting, you will be provided with the opportunity to ask questions.

We are pleased to continue to take advantage of the Securities and Exchange Commission rule allowing companies to furnish proxy materials to their stockholders via the Internet. We believe this e-proxy process, also known as "notice and access," expedites stockholders' receipt of proxy materials, lowers our printing and mailing costs and reduces the environmental impact of producing the materials for our Annual Meeting. On or about March 28, 2017, we will mail to our stockholders of record at the close of business on Wednesday, March 15, 2017, the record date for our Annual Meeting, an Important Notice of Internet Availability of Proxy Materials (Notice) containing instructions on how to access our Proxy Statement and Annual Report for the year ended December 31, 2016 (Annual Report) on the Internet and also how to vote their shares via the Internet. If you received a Notice by mail you will not receive printed proxy materials unless you specifically request them. Both the Notice and the Proxy Statement contain instructions on how you can request a paper copy of the Proxy Statement and Annual Report.

The Board of Directors appreciates and encourages stockholder participation in the Company's affairs. Whether or not you plan to attend the Annual Meeting, we encourage you to vote your shares. Accordingly, we request that as soon as possible, you vote via the Internet or, if you have received printed proxy materials, you vote via the Internet, by telephone or by mailing your completed proxy card or voter instruction form.

Thank you for your continuing support.

PROXY STATEMENT

Information About the Annual Meeting and Voting

The Annual Meeting of Stockholders of Boston Scientific Corporation (Annual Meeting) will be held on Tuesday, May 9, 2017, at 8:00 a.m. Eastern Time, at the Company's Corporate Headquarters located at 300 Boston Scientific Way, Marlborough, Massachusetts 01752. At this meeting, stockholders will be asked to elect ten nominees for director, approve, on a non-binding, advisory basis, named executive officer compensation, approve, on a non-binding, advisory basis, an annual frequency of holding a non-binding, advisory vote on named executive officer compensation, and ratify the appointment of Ernst & Young LLP as our independent registered public accounting firm for the 2017 fiscal year. Management will also report on our performance during fiscal year 2016 and will respond to questions from stockholders. Our principal executive offices are located at 300 Boston Scientific Way, Marlborough, Massachusetts 01752, and our telephone number is (508) 683-4000. When used in this Proxy Statement, the terms "we," "us," "our," "Boston Scientific" and "the Company" mean Boston Scientific Corporation and its businesses and subsidiaries.

Why am I receiving these materials?

In connection with its solicitation of proxies for use at our Annual Meeting, our Board of Directors (Board) (i) has made these materials available to you via the Internet or, upon your request, via email, or (ii) upon your request, has delivered or will deliver printed versions of these materials to you by mail. As a stockholder of record of our common stock at the close of business on March 15, 2017, the record date for our Annual Meeting, you are invited to attend the Annual Meeting, and are entitled to and requested to vote on the items of business described in this Proxy Statement.

Why did I receive a notice in the mail regarding the Internet availability of proxy materials instead of a full set of printed proxy materials?

Pursuant to rules adopted by the Securities and Exchange Commission (SEC), we are making this Proxy Statement and our Annual Report for the year ended December 31, 2016 (Annual Report and, together with this Proxy Statement, the proxy materials) available to stockholders electronically via the Internet. Stockholders will be able to access the proxy materials on the website referred to in the Important Notice of Internet Availability of Proxy Materials (Notice) or request to receive printed copies of the proxy materials and a proxy card. Instructions on how to access the proxy materials via the Internet or to request a printed copy may be found in the Notice and in this Proxy Statement. We

1

---

Table of Contents

believe that this electronic process expedites your receipt of the proxy materials and reduces the cost and environmental impact of printing proxy materials for our Annual Meeting.

On or about March 28, 2017, stockholders of record and beneficial owners of our common stock at the close of business on March 15, 2017, will be sent a Notice instructing them as to how to receive their proxy materials via the Internet. The proxy materials will be available on the Internet as of March 28, 2017.

How can I electronically access the proxy materials?

Beginning March 28, 2017, you can access the proxy materials and vote your shares online at www.proxyvote.com. The proxy materials are also available on our own website (www.bostonscientific.com).

How can I obtain a full set of printed proxy materials?

If you prefer to receive paper copies of the proxy materials and a proxy card, you may still do so. You may request printed materials by (i) calling 1-800-579-1639; (ii) sending an email to sendmaterial@proxyvote.com; or (iii) logging onto www.proxyvote.com using the credentials provided on your Notice or proxy card.

Who is entitled to vote at the Annual Meeting?

Stockholders who held shares of our common stock at the close of business on Wednesday, March 15, 2017, are entitled to vote at the Annual Meeting. Each share of our common stock is entitled to one vote.

How many shares are eligible to be voted and how many shares are required to hold the Annual Meeting?

A quorum is required to hold the Annual Meeting and conduct business. The presence at the Annual Meeting, in person or by proxy, of stockholders holding a majority of our common stock outstanding as of the close of business on Wednesday, March 15, 2017, the record date, will constitute a quorum for purposes of holding and conducting business at the Annual Meeting. As of March 15, 2017, we had 1,368,971,425 shares of our common stock outstanding — each entitled to one vote at the Annual Meeting — meaning that 684,485,713 shares of common stock must be represented in person or by proxy to have a quorum. Our common stock is our only outstanding class of voting securities. For purposes of determining whether a quorum exists, broker non-votes (as described further below) and proxies received but marked "ABSTAIN" will be counted.

What am I voting on?

You are voting on proposals to:

1.

elect to the Board ten nominees for director;



2.

approve, on a non-binding, advisory basis, named executive officer compensation;



3.

approve, on a non-binding, advisory basis, the frequency of future named executive officer compensation advisory votes;

2

Table of Contents

4.

ratify the appointment of Ernst & Young LLP as our independent registered public accounting firm for the 2017 fiscal year; and



5.

consider and vote upon such other business as may properly come before the Annual Meeting or any adjournment or postponement thereof.

How does the Board recommend that I vote?

The Board recommends that you vote:

1.

FOR the election of each of the ten director nominees;



2.

FOR our named executive officer compensation;



3.

FOR an annual frequency of holding a non-binding, advisory vote on named executive officer compensation; and



4.

FOR the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm for the 2017 fiscal year.

How do I vote by proxy?

Your vote is very important. Whether or not you plan to attend the Annual Meeting in person, you may give a proxy to be voted at the Annual Meeting either:

•

via the Internet pursuant to the instructions provided in the Notice; or



•

if you received printed proxy materials, via the Internet or by telephone or mail pursuant to the instructions provided on the proxy card.

If you vote by mail, no postage is required if your proxy card is mailed in the United States. If you properly vote pursuant to the instructions provided in the Notice or properly complete and deliver your proxy card (whether electronically, by mail or by telephone) and our Inspector of Election receives your instructions in time to vote at the Annual Meeting, your "proxy" (one of the individuals named on your proxy card) will vote your shares as you have directed. If you sign and return your proxy card, but do not make specific selections, your proxy will vote your shares as recommended by the Board. If any other matter is properly presented at the Annual Meeting, including a proposal to postpone or adjourn the meeting, your proxy will vote your shares in accordance with his or her discretion. At present, the Board knows of no other business that is intended to be brought before or acted upon at the Annual Meeting.

How are votes counted?

In the election of directors, your vote may be cast "FOR" one or more of the nominees or your vote may be "WITHHELD" with respect to one or more of the nominees. If you sign your proxy card with no further instructions, your shares will be voted in accordance with the recommendation of the Board.

In the advisory vote to approve named executive officer compensation, your vote may be cast "FOR" or "AGAINST" or you may "ABSTAIN." If you "ABSTAIN," it will not count as a share actually voted and

3

---

Table of Contents

will have no effect on the determination of this proposal. If you sign your proxy card with no further instructions, your shares will be voted in accordance with the recommendation of the Board.

In the advisory vote to approve the frequency of future named executive officer compensation advisory votes, you may vote "1 YEAR," "2 YEARS," "3 YEARS" or you may "ABSTAIN." If you "ABSTAIN," it will not count as a share actually voted and will have no effect on the determination of this proposal. If you sign your proxy card with no further instructions, your shares will be voted in accordance with the recommendation of the Board.

In the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm, your vote may be cast "FOR" or "AGAINST" or you may "ABSTAIN." If you "ABSTAIN," it will not count as a share actually voted and will have no effect on the determination of this proposal. If you sign your proxy card with no further instructions, your shares will be voted in accordance with the recommendation of the Board.

How many votes are required to approve each proposal?

1.

Under our By-Laws our directors are elected by plurality vote. That means that for Proposal 1, the ten nominees for director named in this Proxy Statement receiving the most votes from those shares present or represented at the Annual Meeting will be elected as directors. The majority voting policy set forth in our Corporate Governance Guidelines requires that, in an uncontested election, any nominee for director who receives a greater number of votes "WITHHELD" from his or her election than votes "FOR" his or her election shall promptly tender his or her resignation from the Board following the certification of the stockholder vote. The Board will then decide whether to accept the resignation (based on the recommendation of the Nominating and Governance Committee of our Board) within 90 days following certification of the stockholder vote, and will disclose its determination and its reasoning either in a press release and/or an SEC filing.



2.

The affirmative vote of a majority of shares with voting power present in person or represented by proxy and which have actually voted on the proposal is required to approve, on an advisory basis, our named executive officer compensation. The vote is advisory and non-binding in nature, but the Executive Compensation and Human Resources Committee of our Board (Compensation Committee) will take into consideration the outcome of the vote when considering future executive compensation arrangements. You may vote "FOR," "AGAINST" or "ABSTAIN." If you "ABSTAIN," it will be counted for the purpose of determining whether a quorum is present for conducting the Annual Meeting, but it will not count as a share actually voted and will have no effect on the determination of this proposal.



3.

The frequency of holding a non-binding, advisory vote on our named executive officer compensation that receives the most votes "FOR" will be deemed the selection (on a non-binding, advisory basis) of our stockholders. The vote is advisory and non-binding in nature, but our Board will take into consideration the outcome of the vote when determining the frequency of holding an advisory vote on our named executive officer compensation. You may vote "1 YEAR," "2 YEARS," "3 YEARS" or you may "ABSTAIN." If you "ABSTAIN," it will be counted for the purpose of determining whether a quorum is present for conducting the Annual Meeting, but your vote will not count as a share actually voted and will have no effect on the determination of this proposal.



4.

The affirmative vote of a majority of shares with voting power present in person or represented by proxy and which have actually voted on the proposal is required to ratify the

4

---

Table of Contents

appointment of Ernst & Young LLP as our independent registered public accounting firm for the 2017 fiscal year. You may vote "FOR," "AGAINST" or "ABSTAIN." If you "ABSTAIN," it will be counted for the purpose of determining whether a quorum is present for conducting the Annual Meeting, but it will not count as a share actually voted and will have no effect on the determination of this proposal.

At present, the Board knows of no other matters to be presented for stockholder action at the Annual Meeting.

What is the difference between holding shares as a stockholder of record and as a beneficial owner?

Most of our stockholders hold their shares through a broker, trustee, bank, other financial intermediary or other nominee rather than directly in their own name. As summarized below, there are some differences between stockholders of record and beneficial owners.

Stockholders of Record

If your shares are registered directly in your name with our transfer agent, Computershare Shareowner Services, as of the close of business on Wednesday, March 15, 2017, you are considered the stockholder of record with respect to those shares, and the Notice or proxy materials are being made available, electronically or otherwise, directly to you by the Company. As the stockholder of record, you have the right to grant your voting proxy directly to the Company or a third party, or to vote in person at the Annual Meeting. The Company has made available a proxy card or electronic voting means for you to use for voting purposes.

Beneficial Owners

If your shares are held through a brokerage firm, trustee, bank, other financial intermediary or nominee, as of the close of business on Wednesday, March 15, 2017, you are considered the beneficial owner of those shares held in street name, and the Notice or proxy materials are being made available, electronically or otherwise, by the Company to your broker, trustee, bank, other financial intermediary or other nominee (the "intermediary") and they will forward these materials to you, together with a voting instruction form if furnished via paper copy to your intermediary. As the beneficial owner, you have the right to direct your intermediary on how to vote and are also invited to attend the Annual Meeting; however, since you are not the stockholder of record, you may not vote these shares in person at the Annual Meeting, unless you request, complete and deliver a legal proxy from your intermediary. If you requested printed proxy materials, your intermediary will enclose a voting instruction form for you to use in directing the intermediary regarding how to vote your shares.

What discretion does my broker have to vote my shares held in "street name?"

The New York Stock Exchange (NYSE) rules allow your broker to vote your shares in its discretion on "routine" proposals when it has not received instructions from you at least ten days prior to the Annual Meeting. The proposal regarding the ratification of the appointment of our independent registered public accounting firm is a matter considered routine under applicable rules and, therefore, your broker may vote on your behalf for this matter if you do not otherwise provide instructions. The election of directors, the advisory vote on our named executive officer compensation, and the advisory vote on the frequency of future named executive officer compensation advisory votes are not considered routine matters. If you do not instruct your broker how to vote your shares on the

5

---

Table of Contents

non-routine matters, your broker will not be permitted to vote your shares on such matters. This is referred to as a "broker non-vote."

Broker non-votes (shares held by brokers that do not have discretionary authority to vote on the matter and have not received voting instructions from their clients) are counted for purposes of determining whether a quorum is present, but are not counted or deemed to be present, represented or voted for the purpose of determining whether stockholders have approved a proposal. A broker non-vote will have no effect on the outcome of the non-routine proposals voted on at the Annual Meeting.

How do I vote my 401(k) shares?

If you participate in our 401(k) Retirement Savings Plan, as amended and restated (401(k) Plan), you will receive a single proxy card (together with the proxy materials) or Notice that covers all shares credited to your plan account(s) and shares that you own of record that are registered in the same name. If your plan account(s) are registered in different names, you will receive separate proxy cards or Notices for your record and plan holdings. You may vote your shares by following the instructions provided in your proxy card or Notice and utilizing the credentials provided therein. Your vote will serve to instruct the trustees and fiduciaries of our 401(k) Plan how to vote any shares of our common stock held in our 401(k) Plan on your behalf. Shares of our common stock held in our 401(k) Plan must be voted on or before 11:59 p.m. Eastern Time on May 4, 2017. The trustee and fiduciaries of our 401(k) Plan will vote shares for which timely instructions are not received in the same proportion as other plan shares that were voted.

What happens if I don't specify how I want my shares voted on one or all of the proposals?

If you are the stockholder of record and you sign, date and return your proxy and do not mark how you want to vote, your proxy will be counted as a vote "FOR" all of the nominees for directors, "FOR" our named executive officer compensation, "FOR" an annual frequency of holding a non-binding, advisory vote on named executive officer compensation, and "FOR" the ratification of our independent registered public accounting firm, Ernst & Young. If you hold your shares in street name, please see the discussion on "What discretion does my broker have to vote my shares held in 'street name?'," above.

Can I change my vote or revoke my proxy after I have already voted or given my proxy?

Yes. If you are a stockholder of record, you may change your vote or revoke your proxy at any time before the proxy is voted at the Annual Meeting. To change your vote, you may:

•

mail a written notice "revoking" your earlier vote to Broadridge Financial Solutions, Inc. (Broadridge), 51 Mercedes Way, Edgewood, NY 11717;



•

submit to Broadridge a properly completed and signed proxy card with a later date;



•

vote again telephonically or electronically (available until 11:59 p.m. Eastern Time on May 8, 2017); or



•

vote in person at the Annual Meeting; however, your attendance at the Annual Meeting alone will not revoke your proxy.

Your last dated proxy, properly completed and timely received prior to, or vote cast at, the Annual Meeting will be counted.

6

---

Table of Contents

If you own your shares in street name, please contact your broker or other intermediary for instructions on changing your vote or revoking your proxy.

Can I vote in person at the meeting?

Yes. If you are the stockholder of record of the shares, you can vote in person by coming to the Annual Meeting, and we will give you a ballot or a new proxy card when you arrive with proper identification. However, since a beneficial owner holding shares in street name is not the stockholder of record, if you are such a beneficial owner of shares, you may not vote your shares in person at the Annual Meeting unless you obtain a legal proxy from the broker or other intermediary that holds your shares giving you the right to vote the shares at the Annual Meeting. Please bring the legal proxy with you to the Annual Meeting. If you plan to attend the Annual Meeting in person, you must provide proper identification. Please visit our website, www.bostonscientific.com, for directions to the Annual Meeting.

Who will count the votes?

Broadridge has been engaged as our independent agent to tabulate stockholder votes and act as Inspector of Election for the meeting.

Is voting confidential?

Proxy instructions, ballots and voting tabulations that identify individual stockholders are handled in a manner that protects your voting privacy. Your vote will not be disclosed either within the Company or to third parties, except:

•

as necessary to meet applicable legal requirements;



•

to allow for the tabulation and certification of votes; and



•

to facilitate a successful proxy solicitation.

Occasionally, stockholders provide written comments on their proxy cards, which may be forwarded to the Company's management and the Board.

What happens if the Annual Meeting is adjourned or postponed?

Your proxy will still be effective and will be voted at the rescheduled Annual Meeting. You will still be able to change or revoke your proxy until it is voted, provided such new proxy or revocation is properly completed and timely received.

Will any other business be considered or presented at the Annual Meeting?

Our By-Laws provide that a stockholder may present business to be considered at the Annual Meeting only if proper prior written notice was timely received by us. Other than the items of business described in this Proxy Statement, our Board is not aware of any other business to be acted upon at the Annual Meeting; however, if any other business does properly come before the Annual Meeting, the persons named as proxies on the proxy card will vote your shares in accordance with their discretion.

Table of Contents

How can I find the results of the Annual Meeting?

We will report the final voting results on a Current Report on Form 8-K filed with the SEC within four business days after the Annual Meeting. The Form 8-K will be available on the SEC's website, www.sec.gov, as well as on our own website, www.bostonscientific.com, under the "Investor Relations" section.

Who is soliciting my vote pursuant to this Proxy Statement?

Our Board is soliciting your vote.

Is there a list of stockholders entitled to vote at the Annual Meeting?

A list of stockholders entitled to vote at the Annual Meeting will be available at the Annual Meeting and for ten days prior to the Annual Meeting, between the hours of 8:30 a.m. and 5:00 p.m. Eastern Time, at our Corporate Headquarters located at 300 Boston Scientific Way, Marlborough, Massachusetts 01752. If you would like to view the stockholder list, please contact our Secretary to schedule an appointment by calling (508) 683-4000 or writing to him at 300 Boston Scientific Way, Marlborough, Massachusetts 01752.

Internet Availability of Proxy Materials

Under rules adopted by the SEC, we are furnishing proxy materials to our stockholders primarily via the Internet instead of mailing printed copies of those materials to each stockholder. On or about March 28, 2017, we will mail to our stockholders (other than those who previously requested electronic or paper delivery) an Important Notice of Internet Availability of Proxy Materials containing instructions on how to access our proxy materials, including our Proxy Statement and our Annual Report. The Notice also instructs stockholders on how to vote via the Internet.

This process is designed to expedite stockholders' receipt of proxy materials, lower the cost of the Annual Meeting and help conserve natural resources; however, if you would prefer to receive printed proxy materials and a proxy card, please follow the instructions included in the Notice and in this Proxy Statement. If you have previously elected to receive our proxy materials electronically, these materials will continue to be made available to you via email until you elect otherwise. If you have previously elected to receive printed proxy materials, you will continue to receive these materials and a proxy card in paper format until you elect otherwise.

Cautionary Statement Regarding Forward-Looking and Other Statements

This Proxy Statement contains forward-looking statements within the meaning of the federal securities laws. Forward-looking statements may be identified by words like "anticipate," "expect," "project," "believe," "plan," "may," "estimate," "intend" and other similar words. These forward-looking statements are based on our beliefs, assumptions and estimates using information available to us at the time and are not intended to be guarantees of future events or performance. Factors that may cause actual results to differ materially from those contemplated by the statements in this Proxy Statement can be found in our most recent Annual Report on Form 10-K filed with the SEC and in the Quarterly Reports on Form 10-Q that we have filed or will file hereafter under the heading "Risk Factors" and "Safe Harbor for Forward-Looking Statements." The forward-looking statements speak only as of the date of this Proxy Statement and undue reliance should not be placed on these statements. We disclaim any intention or obligation to publicly update or revise any forward-looking statements. This cautionary statement is applicable to all forward-looking statements contained in this document.

This Proxy Statement contains statements regarding individual and Company performance objectives and targets.

We specifically caution investors not to apply these statements to other contexts.

PROPOSAL 1: ELECTION OF DIRECTORS

Our entire Board is elected annually by our stockholders and currently consists of eleven members. John E. Abele, our co-founder, has served at the request of the Board as director emeritus since his retirement from the Board at the 2011 Annual Meeting of Stockholders so that the Board may continue to avail itself of his wisdom, judgment, and experience. Serving as director emeritus, Mr. Abele may attend Board and committee meetings and participate in discussion of matters that come before the Board or its committees, but he is not a director and is not entitled to vote upon any such matters.

On January 16, 2017, Kristina M. Johnson, Ph.D., a director of Boston Scientific since January 2011 as well as from April 2006 to May 2009, advised us that she would not be standing for re-election to the Board at the Annual Meeting. We are deeply grateful for the enormous contributions that Dr. Johnson has made to our Company, our Board and our stockholders.

On July 11, 2016, the Board, upon the recommendation of the Nominating and Governance Committee, appointed Yoshiaki Fujimori to serve on the Board, effective July 13, 2016, to hold office until the Annual Meeting.

In light of the departure of one director, ten of our directors have been nominated by our Board, upon the recommendation of our Nominating and Governance Committee, to stand for election at the Annual Meeting for a one-year term, to hold office until the 2018 Annual Meeting of Stockholders and until their successors have been elected and qualified. The nominees for election at the Annual Meeting are: Nelda J. Connors, Charles J. Dockendorff, Yoshiaki Fujimori, Donna A. James, Edward J. Ludwig, Stephen P. MacMillan, Michael F. Mahoney, David J. Roux, John E. Sununu and Ellen M. Zane.

Each of the director nominees is willing and able to stand for election at the Annual Meeting, and we know of no reason why any of the nominees would be unable to serve as a director. Should such a situation arise, however, the Board may designate a substitute nominee or, alternatively, reduce the number of directors to be elected. If a substitute nominee is selected, the persons named as proxies will vote for that substitute nominee. Any vacancies not filled at the Annual Meeting may be filled by the Board.

The biographies of each of the nominees are listed below and contain information regarding the person's service as a director, business experience, public company director positions currently held or held at any time during the last five years, information regarding involvement in certain legal or administrative proceedings (if applicable) and the experiences, qualifications, attributes or skills that caused the Nominating and Governance Committee and the Board to determine that the person should serve as a director in light of our business and structure. Each of the director nominees listed below exemplifies how our Board values professional experience in business, education, policy and governmental fields as well as strong moral character and diversity in terms of viewpoint as well as age, ethnicity and gender. Our Board believes that these strong backgrounds and sets of skills provide it, as a whole, with a strong foundation of technical expertise and a wealth of diverse experience in a wide variety of areas.

CORPORATE GOVERNANCE

To guide the operation and direction of the Board and its committees, our Board has established our Corporate Governance Guidelines, charters for its standing committees and our Code of Conduct to reflect our commitment to good corporate governance and to comply with Delaware law, the rules and listing standards of the NYSE, the rules and regulations of the SEC and other legal requirements. These materials are available under "Corporate Governance" in the "Investor Relations" section of our website at www.bostonscientific.com. These materials are also available in print free of charge to stockholders, upon written request to Boston Scientific Corporation, Investor Relations, 300 Boston Scientific Way, Marlborough, Massachusetts 01752.

Our Board believes that good corporate governance is fundamental to the overall success of our business. To that end, our Board evaluates our corporate governance practices in light of applicable changes in Delaware law, the rules and listing standards of the NYSE, the rules and regulations of the SEC and the rules and regulations under the Internal Revenue Code, as well as best practices suggested by recognized governance authorities, and makes modifications to our corporate governance practices that it determines are warranted.

Under the NYSE's Corporate Governance Standards, a majority of the Board must qualify as independent directors. However, our Corporate Governance Guidelines require that a significant majority of the Board qualify as independent directors. The NYSE Corporate Governance Standards define specific relationships that disqualify directors from being independent and further require that for a director to qualify as independent, the Board must affirmatively determine that the director has no material relationship with our Company (either directly or as a partner, stockholder or officer of an organization that has a relationship with our Company).

In making determinations regarding independence, the Board applies the NYSE standards and broadly considers all relevant facts and circumstances known to it. In addition, in making independence determinations with respect to directors who will serve on the Compensation Committee, the Board considers all factors specifically relevant to determining whether a director has a relationship with our Company that is material to that director's ability to be independent from management in connection with the duties of a Compensation Committee member, including, but not limited to: (i) the source of compensation of such director, including any consulting, advisory or other compensatory fee paid by our Company to such director, and (ii) whether such director is affiliated with our Company, a subsidiary of our Company or an affiliate of a subsidiary of our Company — as required by the NYSE independence standards for compensation committee members.

The Board has determined that the following directors are independent under the independence standards set forth in the NYSE Corporate Governance Standards: Nelda J. Connors, Charles J. Dockendorff, Yoshiaki Fujimori, Donna A. James, Kristina M. Johnson, Edward J. Ludwig, Stephen P. MacMillan, David J. Roux, John E. Sununu and Ellen M. Zane.

The Board monitors its compliance with NYSE requirements for director independence on an ongoing basis, including through an annual review of director questionnaires and consideration of transactions and relationships between each director or any member of his or her immediate family and the Company as well as other relevant facts and circumstances. The Board and the Nominating and

Table of Contents

Governance Committee considered the directors' responses to a questionnaire asking about their relationships with the Company (and their immediate family members' relationships with the Company) and other potential conflicts of interest, as well as material provided by management related to transactions, relationships, or arrangements between the Company and the directors or parties related to the directors. The Board made its determination as to whether any relationship between a director and our Company is a material relationship based on the facts and circumstances of the relationship, the amounts involved in the relationship, the director's interest in such relationship, if any, and such other factors as the Board, in its judgment, deemed appropriate.

The Nominating and Governance Committee is responsible for determining the appropriate skills and characteristics required of new Board members in the context of the current make-up of the Board. In so doing, the Nominating and Governance Committee considers, with input from the Board, those factors it deems appropriate, such as independence, experience, strength of character, judgment, technical skills, diversity, years of experience and the extent to which the individual would fill a present need on the Board. The aim is to assemble a Board that is strong in its collective knowledge and that consists of individuals who bring a variety of complementary attributes and who, taken together, have the appropriate skills and experience to oversee the Company's business. The Nominating and Governance Committee considers diversity as one of a number of factors in identifying nominees for director. It does not, however, have a formal policy in this regard. The Nominating and Governance Committee views diversity broadly to include diversity of experience, skills and viewpoint as well as other diversity concepts such as ethnicity and gender.

Director nominees must, at a minimum, meet the general criteria outlined in our Corporate Governance Guidelines. Generally, directors should be individuals who have succeeded in their particular field and who demonstrate integrity, reliability, knowledge of corporate affairs and an ability to work well with others, and should also satisfy at least one of the following criteria:

•

demonstrated management ability at senior levels in successful organizations;



•

current or recent employment in positions of significant responsibility and decision making;



•

expertise in leading rapidly growing multi-national organizations; or



•

current and prior experience related to anticipated board and committee responsibilities in other areas of importance to our Company.

The Nominating and Governance Committee receives suggestions for new directors from a number of sources, including Board members and our Chief Executive Officer. It also may, in its discretion, employ a third-party search firm to assist in identifying candidates for director.

The Nominating and Governance Committee will also consider recommendations for Board membership submitted by our stockholders and other sources in accordance with the advance notice provisions of our By-Laws. The qualifications of candidates recommended by stockholders will be reviewed and considered by the Nominating and Governance Committee with the same degree of care and consideration as candidates for nomination to the Board submitted by Board members and our Chief Executive Officer.

The full Board is responsible for final approval of new director candidates, as well as the nomination of existing directors for reelection. With respect to existing directors, prior to making its recommendation to the full Board, the Nominating and Governance Committee, in consultation with the Chairman of the Board, reviews each director's continuation on the Board as a regular part of the annual nominating process.

Under the advance notice provisions of our By-Laws, director nominations and proposals to bring any other business before the 2018 Annual Meeting of Stockholders by our stockholders must be received by our Secretary at our principal executive offices on or before November 28, 2017. Director nominations by our stockholders must also satisfy the other procedures set forth in the advance notice provisions of our By-Laws. Should you wish to submit a director recommendation or nomination, have it addressed to our Secretary at Boston Scientific Corporation, 300 Boston Scientific Way, Marlborough, Massachusetts 01752.

We maintain a Code of Conduct, which has been approved by our Board, to ensure that our directors, employees, and officers, including our Chief Executive Officer and Chief Financial Officer, understand the basic principles that govern our corporate conduct. The Code of Conduct is available under "Corporate Governance" in the "Investor Relations" section of our website at www.bostonscientific.com. A stockholder may request a copy of the Code of Conduct by contacting our Secretary at Boston Scientific Corporation, 300 Boston Scientific Way, Marlborough, Massachusetts 01752. Any waivers or substantive amendments of the Code of Conduct will be disclosed on our website at www.bostonscientific.com.

Pursuant to our Corporate Governance Guidelines, the Nominating and Governance Committee reports to the full Board periodically on succession planning for our Chief Executive Officer (and other executive officers, as appropriate). Our Chief Executive Officer discusses with the Board and the Nominating and Governance Committee at least once per year, his recommendations and evaluations of potential successors to his position, including in the event of an unexpected emergency, and reviews development plans, if any, recommended for such individuals.

Our Board believes that it is important that it retain flexibility to make the determination as to whether the interests of the Company and our stockholders are best served by having the same individual serve as both Chief Executive Officer and Chairman of the Board or whether the roles should be separated based on the circumstances at any given time. Under our Corporate Governance Guidelines, the Board will appoint a Lead Independent Director when the Chief Executive Officer and Chairman of the Board roles are combined or if the Chairman is not otherwise independent. The Lead Independent Director will preside over meetings of our non-management directors, serve as liaison between our Chairman and the independent directors, work with the Chairman to establish agendas for Board and committee meetings, raise issues with management on behalf of the independent directors, consult with committee leadership, and carry out other duties as requested by the Board.

Mr. Mahoney has been our President and Chief Executive Officer since November 2012 and Chairman since May 2016. In light of the fact that the Chief Executive Officer and Chairman of the Board roles have been combined since May 2016, the Board appointed Mr. Ludwig at that time to serve as Lead

Independent Director. Our Board believes that this leadership structure, coupled with a commitment to Board independence, provides effective independent oversight of management, while fostering a constructive and cooperative relationship between the Board and management and allowing both the Board and management to benefit from Mr. Mahoney's day-to-day familiarity with our business operations.

Our Board oversees an enterprise-wide approach to risk management, designed to support the achievement of our strategic and organizational objectives, to improve long-term organizational performance and to enhance stockholder value. A fundamental part of risk oversight is to understand the individual risks our Company faces, the steps management is taking to manage those risks, including the framework used by management for the coordinated oversight, control, and continuous improvement of processes used to manage risk, and to assess management's appetite for risk. It is management's responsibility to manage risk and bring to the Board's attention material risks facing our Company. Our Board receives regular reports from management on matters relating to strategic and operational initiatives, financial performance and legal developments, which are each integrated with enterprise-risk exposures. The involvement of the full Board in approving our strategic plan is a key part of its assessment of the risks inherent in our corporate strategy.

While the Board has the ultimate responsibility for risk oversight, each committee of the Board also oversees risk to the extent that it relates to the committee's responsibilities, as outlined below:

•

The Audit Committee focuses on financial risk, including internal controls, legal and regulatory risks, as well as compliance risks of a financial nature, including those related to federal healthcare programs and healthcare providers, and receives an annual risk assessment report from our internal auditors. It also assists the Board in fulfilling its oversight responsibility with respect to compliance risks of a non-financial nature, including those related to federal healthcare programs and healthcare providers, and regulatory, quality and product safety issues that affect us. The Audit Committee receives an annual risk assessment from our global compliance group.



•

The Finance Committee focuses on risk exposure and risk management strategies associated with our strategic initiatives, current and potential investments, as well as cash, debt and equity management and our ongoing ability to access capital markets. In addition, the Finance Committee consults with the Audit Committee, as necessary, to share information pertinent to the Audit Committee's consideration and oversight of the Company's risk and risk management programs and policies.



•

The Executive Compensation and Human Resources Committee evaluates and sets compensation programs that encourage decision-making predicated upon a level of risk consistent with our business strategy. The Executive Compensation and Human Resources Committee also reviews compensation and benefit plans affecting employees in addition to those applicable to executive officers.



•

The Nominating and Governance Committee oversees governance and succession risk, including Board and Chief Executive Officer succession, and evaluates director skills and qualifications to ensure the appropriate appointment of particular directors to our standing committees based upon the needs of that committee. Each committee makes reports in its respective area of responsibility to the Board at the next regularly scheduled Board meeting

19

Table of Contents

immediately following the committee meeting. Such reports may identify current risks impacting each committee's areas of responsibility to the extent such risks were addressed at the earlier meeting.

Since the 2016 Annual Meeting, the offices of Chief Executive Officer and Chairman of the Board have been held by Mr. Mahoney, and Mr. Ludwig, an independent director, has served as Lead Independent Director. Given the Board's role in risk oversight, it believes that any leadership structure that it adopts must allow it to effectively oversee the management of the risks relating to our operations. Although there are different leadership structures that could allow our Board to oversee the management of such risks effectively, and while our Board believes our current leadership structure will enable it to manage such risks effectively, it was one factor among many considered by our Board in selecting this leadership structure over other potential alternatives. For a discussion of the reasons why our Board has determined that its leadership structure is appropriate, please see the "Board Leadership Structure" above.

Stockholders and other interested parties who wish to communicate directly with any member of our Board, or our non-management directors as a group, may do so by writing to the Board of Directors or Non-Management Directors, Boston Scientific Corporation, c/o General Counsel, 300 Boston Scientific Way, Marlborough, Massachusetts 01752 or by contacting the Board via email at BSCboardofdirectors@bsci.com or non-management directors via email at non-managementdirectors@bsci.com. The Board has authorized the office of our General Counsel to review and organize, but not screen, communications from stockholders and other interested parties and deliver them to the Board or non-management directors, as applicable. We do screen commercial solicitations for appropriateness.

Without the approval of the Nominating and Governance Committee, no director may sit on more than four public company boards (including our Board) and our Chief Executive Officer may not sit on more than one public company board (in addition to our Board). No member of the Audit Committee may serve on the audit committee of more than three public companies, including our Company. All of our Board members have complied with these limitations or procedures.

Our Board has adopted a written related party transaction policy to monitor transactions, arrangements or relationships in which the Company and any of the following have an interest: (i) any person who is or was (since the beginning of 2016, even if they do not presently serve in that role) an executive officer or director or director nominee; (ii) any person who is a director emeritus; (iii) any person or entity who holds more than a 5% beneficial ownership of our common stock; (iv) any immediate family member of any of the foregoing; or (v) any entity in which any of the foregoing persons is employed or is a general partner or principal or acts in any similar position in which such person or persons collectively have a 10% or greater beneficial ownership interest. The policy covers any related party transaction that meets the minimum threshold for disclosure under relevant SEC rules (generally, transactions involving amounts exceeding $120,000 in which a related person has a direct or indirect material interest).

Related party transaction oversight is the responsibility of our Nominating and Governance Committee. Our General Counsel is responsible for identifying any potential related party transactions and, if he

20

---

Table of Contents

determines that an existing or proposed transaction constitutes a related party transaction under the policy, he will provide relevant details and an analysis of the related party transaction to the Nominating and Governance Committee. The General Counsel provides an annual summary to the Nominating and Governance Committee of all transactions or relationships which he considered under this policy, including those that he determined do not constitute a related party transaction. If the General Counsel has an interest in a potential related party transaction, he will provide all relevant information to the Chairperson of the Nominating and Governance Committee who will provide the information to the other members of such Committee. The Nominating and Governance Committee reviews relevant information concerning any existing or proposed transaction contemplated by the Company with an entity that is the subject of a disclosed relationship, and approves or rejects the transaction, with or without conditions or additional protections for the Company. Our related party transactions policy can be found in our Corporate Governance Guidelines available under "Corporate Governance" in the "Investor Relations" section of our website at www.bostonscientific.com.

In December 2013, following approval by the Nominating and Governance Committee, the Company entered into an arrangement with Mr. Pete M. Nicholas, our co-founder and former Chairman of the Board, to provide office space in accordance with his founders' benefits to assist him in the performance of his duties as then Chairman and other services provided to the Company. This office space is provided to Mr. Pete M. Nicholas at a monthly amount of $3,750 (for a total of $45,000 per year), subject to renewal annually at the same rate, and to reimburse up to $50,000 in aggregate amount of documented renovation expenses, including for the installation of secure telephone- and data-lines and/or such other protections required by the Company.

MEETINGS AND BOARD COMMITTEES

The Board met six times in 2016. In 2016, each incumbent director attended at least 75% of the aggregate of (1) the total number of meetings of our Board of Directors (held during the period for which he or she has been a director) and (2) the total number of meetings of all committees of our Board of Directors on which the director served (during the periods that he or she served).

Directors who qualify as independent directors within the meaning of the NYSE Corporate Governance Standards meet in executive sessions without management at every regularly scheduled Board meeting and at such other times as they deem appropriate. Our independent directors meet in executive session at least once annually. In 2016, our independent directors met in executive session without non-independent directors four times. The Chairman of the Board, if independent, or the Lead Independent Director, if the Chairman of the Board is not independent, will preside at executive sessions of independent directors. In his absence, the Chairperson of the Nominating and Governance Committee presides at these executive sessions, and, in his absence, the Chairperson of the Audit Committee presides.

Directors are expected to prepare for and use reasonable efforts to participate in all Board meetings and meetings of the committees on which they serve. The Board and each committee will meet as frequently as necessary to properly discharge their responsibilities, provided that the full Board will meet at least four times per year. Generally, the Board meets in February, May, August, and November. In addition, directors are expected to use reasonable efforts to attend Annual Meetings of Stockholders. At our 2016 Annual Meeting of Stockholders, all of our directors at the time of such meeting were in attendance.

Our Board has standing Audit, Executive Compensation and Human Resources, Nominating and Governance, and Finance Committees. All of the members of the Audit Committee, Executive Compensation and Human Resources Committee, and Nominating and Governance Committee meet the applicable independence requirements of the NYSE and the SEC. Our Board also establishes special committees from time to time to address specific issues or discrete matters as the need arises.

As of March 6, 2017, our committee membership was as follows:

Our Audit Committee met nine times in 2016. Our Audit Committee is comprised of Messrs. Dockendorff, Ludwig, Roux and Sununu and Ms. Zane, each of whom meets the independence requirements of the NYSE and the SEC. The Board has also determined that each of Messrs. Dockendorff, Ludwig and Sununu and Ms. Zane is an "audit committee financial expert" as that term is defined in the rules and regulations of the SEC.

The Audit Committee is governed by a written charter approved by our Board, which is subject to review on an annual basis. As outlined in its written charter (which is available under "Corporate Governance" in the "Investor Relations" section of our website at www.bostonscientific.com), the primary purpose of the Audit Committee is to provide oversight of our accounting and financial reporting processes and audits of our financial statements, as well as of our global compliance program, including matters related to compliance with financial, legal and regulatory requirements. The Audit Committee primarily provides assistance to our Board in the areas of corporate accounting, internal control, independent audit and reporting practices, and maintains, by way of regularly scheduled meetings, a direct line of communication among our directors, management, our internal auditors and our independent registered public accounting firm. The Audit Committee appoints our independent registered public accounting firm, evaluates its qualifications, independence and performance, and reviews its reports and other services. In addition, the Audit Committee pre-approves audit, audit-related and non-audit services performed for us by our independent registered public accounting firm and has the right to terminate our independent registered public accounting firm. The Audit Committee also assists the Board in its oversight of financial, legal and regulatory compliance, including financial reporting, internal controls and financial risk exposure to the Company resulting from legal and regulatory compliance matters, and all other areas of compliance. The Audit Committee Report can be found on page 96 of this Proxy Statement.

Our Executive Compensation and Human Resources Committee (the "Compensation Committee") met four times in 2016. The Compensation Committee is, and has been during 2016, comprised exclusively of "independent directors," as defined by the NYSE, including under the heightened independence standards applicable to compensation committee members, "non-employee directors" within the meaning of Rule 16b-3 promulgated under the Securities Exchange Act of 1934, as amended (Exchange Act), and "outside directors" within the meaning of Section 162(m) of the Internal Revenue Code.

As outlined in its written charter (which is available under "Corporate Governance" in the "Investor Relations" section of our website at www.bostonscientific.com), the Compensation Committee has the authority, among other things, to:

•

set the corporate goals and objectives relative to the Chief Executive Officer's compensation and evaluate the Chief Executive Officer's performance against those goals and objectives;



•

determine and approve our Chief Executive Officer's compensation;



•

review, oversee and determine (or make recommendations to the Board regarding) the total compensation package for our other executive officers;



•

review and make recommendations to the Board regarding all new employment, consulting, retirement, severance and change in control agreements, indemnification agreements and other arrangements proposed for our executive officers and periodically review and evaluate these arrangements for continuing appropriateness;



•

review and make recommendations to the Board regarding the compensation of our non-employee directors;



•

adopt and periodically review a comprehensive statement of executive compensation philosophy, strategy and principles; and



•

review and discuss with management how the Company's compensation policies and programs for all of its employees may create incentives that can affect risk and the management of that risk, as well as whether the Company's compensation programs are appropriately aligned with the Company's risk management.

The Compensation Committee may delegate its authority and duties to subcommittees or individual members of the Compensation Committee, as it deems appropriate in accordance with applicable laws and regulations. The Compensation Committee has delegated authority to our Chief Executive Officer to make equity grants to new hires who are not executive officers within predetermined guidelines. These grants are reviewed with the Compensation Committee at its next regularly scheduled meeting.

Pursuant to its charter, the Compensation Committee has sole authority to retain or obtain advice from any compensation consultant, legal counsel or other advisor, as the Compensation Committee deems appropriate to assist the Committee in the performance of its duties, including the sole authority to approve the compensation and other terms and conditions of retention. Prior to any such retention, the Compensation Committee considers any factors relevant to such consultant's, legal counsel's or advisor's independence from management, including the factors specified in the NYSE Corporate Governance Standards or other listing rules, to evaluate whether the services to be performed will

Table of Contents

raise any conflict of interest or compromise the independence of such consultant, legal counsel or advisor. In May 2016, the Compensation Committee renewed the engagement of the independent compensation consultant Frederic W. Cook & Co., Inc. (FW Cook) to provide advisory services, including a market perspective on executive and director compensation matters. During 2016, FW Cook provided the following compensation services to the Compensation Committee:

•

reviewed and recommended the peer group of companies used in evaluating executive and director compensation;



•

provided information and commentary on executive and director compensation trends as they related to our current compensation programs;



•

collected and analyzed market data on director and executive compensation;



•

reviewed and provided commentary and recommendations on our executive and director compensation arrangements in comparison to market; and



•

reviewed and provided commentary on developments regarding proxy disclosures and management proposals concerning executive pay.

For additional information regarding the services provided by FW Cook, please see the Compensation Discussion & Analysis section.

In 2016, FW Cook and its affiliates did not provide additional services to the Company other than at the request of the Compensation Committee. After review and consultation with FW Cook, the Compensation Committee determined that FW Cook is independent, and there is no conflict of interest resulting from retaining FW Cook currently or during 2016. In reaching these conclusions, the Compensation Committee considered the factors set forth in the SEC rules and the NYSE listing standards.

In accordance with its annual review of its compensation consultant engagement, the Compensation Committee will evaluate the engagement of FW Cook in May 2017.

The Compensation Committee Report can be found on page 64 of this Proxy Statement.

The Nominating and Governance Committee met four times in 2016. The Nominating and Governance Committee is comprised exclusively of non-employee directors, all of whom meet the independence requirements of the NYSE.

As outlined in its written charter (which is available under "Corporate Governance" in the "Investor Relations" section of our website at www.bostonscientific.com), the Nominating and Governance Committee has responsibility for recommending nominees for election and re-election to the Board, ensuring that Board nominees are qualified and consistent with our needs, monitoring significant developments in the law and practice of corporate governance for directors of public companies, recommending Board committee assignments, reviewing and recommending Board policies and procedures, reviewing political contributions made by the Company, monitoring compliance with our stock ownership guidelines and with our related party transactions and board service policies, and overseeing the Board and each committee of the Board in their annual performance self-evaluations. In

25

addition, the Nominating and Governance Committee is responsible for recommending to the Board candidates for Chairperson and Chief Executive Officer and for reviewing and assessing a succession plan for the Chief Executive Officer. For additional information on the nomination process conducted by the Nominating and Governance Committee and our policies regarding stockholder nominations of directors, please see the Corporate Governance section titled "Director Nomination Process."

The Nominating and Governance Committee is responsible for reviewing with the Board, on an annual basis, the current size, structure and composition of the Board as a whole, and whether the Company is being well served by the current directors taking into account the following: the directors' degree of independence; business background, including any areas of particular expertise, such as accounting or related financial management expertise, marketing or technology; record of service (for incumbent directors), including attendance record; meeting preparation; overall contribution to the Board; employment status; gender; ethnicity; years of experience; availability for service to us; and our anticipated needs.

The Finance Committee met four times in 2016. The primary role of the Finance Committee is to provide a forum within the Board to review our overall financing plans and long-term strategic objectives, as well as our shorter-term acquisition and investment strategies and how these shorter-term activities fit within our overall business objectives. As outlined in its written charter (which is available under "Corporate Governance" in the "Investor Relations" section of our website at www.bostonscientific.com), the Finance Committee is charged with providing Board oversight of the financial management of the Company, approving strategic transactions for which the Board has delegated authority, making recommendations to the Board regarding larger transactions, and evaluating our financial strategies and policies. The Finance Committee has responsibility to review periodically with management our strategic business objectives and the manner in which transactional activity can contribute to the achievement of those objectives, and to review with management on a regular basis contemplated strategic opportunities. The Finance Committee conducts periodic reviews of completed transactions for the purposes of assessing the degree of success achieved, testing the extent to which the projections and other assumptions relied upon in approving past transactions have borne out, identifying the factors differentiating more successful transactions from less successful ones and evaluating the strategic contributions resulting from these transactions. The Finance Committee is further charged with conducting periodic reviews of our cash investments and cash management policies, debt ratings and global financing objectives and strategies, including the review and approval of certain borrowing arrangements, capital expenditures and dispositions, and activities that may impact our capital structure.

The members of our Compensation Committee during 2016 were Ms. Connors, Ms. James, Dr. Johnson, Mr. Ludwig and Mr. MacMillan. None of these Compensation Committee members is or has ever been an officer or employee of our Company. During 2016, no member of the Compensation Committee had a relationship that must be described under the SEC rules relating to disclosure of related person transactions. In 2016, none of our executive officers served on the board of directors or compensation committee (or other board committee performing equivalent functions) of any entity that had one or more of its executive officers serving on the Board or the Compensation Committee of the Company.

DIRECTOR COMPENSATION

The Compensation Committee evaluates the appropriate level and form of compensation for non-employee directors at least annually and recommends changes to our Board when appropriate. Non-employee directors receive a combination of cash and equity compensation for their service on our Board. To determine the appropriate level of compensation for 2016, the Compensation Committee relied on the consulting services of FW Cook, as well as publicly available data describing director compensation in our peer group companies. The Compensation Committee also took into consideration the significant amount of time and dedication required by our directors to fulfill their duties on our Board and Board committees as well as the need to continue to attract highly qualified candidates to serve on our Board. Our director compensation is as follows:

Non-Employee Directors

2016 Compensation

In 2016, we compensated our non-employee directors (other than our former Chairman of the Board) as described below:

•

an annual cash retainer of $90,000;



•

an annual grant of equity with a value of $185,000; and



•

an annual cash fee of $20,000 for the chair of each of our Board committees.

The equity granted to our non-employee directors may be granted in one of three forms, as discussed in greater detail below, and vests on the date of the annual meeting of stockholders immediately following the date of grant, subject to the director's continuation of service during such term. The grants are also subject to the terms and conditions of our Long-Term Incentive Plans. The annual equity grants are made on the date of each annual meeting of stockholders. If a non-employee director is appointed to the Board on a date other than the annual meeting of stockholders, however, an equity grant in an amount equal to the then-current non-employee director annual award, prorated for the time period from the effective date of the appointment to the next annual meeting of stockholders, is made on the first trading day of the month following the month in which the new director was appointed to the Board. Such awards made to new non-employee directors become free from restriction upon the expiration of the new director's current term of office on the date of the annual meeting of stockholders immediately following the date of grant, subject to the director's continuation of service during such term. Additionally, if a non-employee director is appointed to the Board on a date other than the annual meeting of stockholders, the annual cash retainer for such director will be prorated for the time period from the effective date of the appointment to the next annual meeting of stockholders.

Cash Compensation

Each non-employee director receives his or her cash retainers and fees, payable on a quarterly basis. Each non-employee director, however, may elect to convert all or a portion of his or her cash compensation into one or more of three equity alternatives, each to vest on the date of the annual meeting of stockholders immediately following the date of grant, subject to the director's continuation

27

Table of Contents

of service during such term: (i) restricted stock valued based on the closing price of our common stock on the date of grant; (ii) stock options valued based on a Black Scholes valuation on the date of grant and exercisable for up to one year after a director's separation from Board service; and/or (iii) deferred stock units, valued based on the closing price of our common stock on the date of grant (with shares of our common stock to be issued only after a director's separation from Board service in accordance with the Boston Scientific Non-Employee Director Deferred Compensation Plan, as amended and restated, effective January 1, 2014 (the 2014 Non-Employee Director Deferred Compensation Plan)). Each non-employee director may also choose to defer receipt of all or a portion of his or her annual cash compensation under the 2014 Non-Employee Director Deferred Compensation Plan, as described further below.

Equity Compensation

Each non-employee director may elect to receive their annual equity award as one or more of the following three equity compensation alternatives, each to vest on the date of the annual meeting of stockholders immediately following the date of grant, subject to the director's continuation of service during such term: (i) restricted stock valued based on the closing price of our common stock on the date of grant; (ii) stock options valued based on a Black Scholes valuation on the date of grant and exercisable until the earlier of ten years from the date of grant or one year after a director's separation from Board service; and/or (iii) deferred stock units valued based on the closing price of our common stock on the date of grant (with shares of our common stock to be issued only after a director's separation from Board service in accordance with the 2014 Non-Employee Director Deferred Compensation Plan).

Lead Independent Director

Beginning in March 2016, we have paid an annual cash fee of $40,000 to our Lead Independent Director. Mr. Ludwig currently serves as Lead Independent Director. Please see the "Board Leadership Structure" above.

Employee Directors

Directors who are also employees of the Company receive no additional compensation for serving on the Board or its committees.

Other Payments and Benefits

We pay or reimburse our directors for transportation, hotel, meals and other incidental expenses incurred in connection with their performance of services for us, including attending Board and committee meetings and participating in director education programs. Our corporate aircraft is made available to our directors for travel to and from our Board meetings, as well as for certain other Company business travel. We also extend directors' and officers' indemnity insurance coverage to each of our directors.

Non-Employee Director Deferred Compensation Plans

Each non-employee director may, by written election, defer receipt of all or a portion of the annual cash retainer, annual cash committee chair fees and equity compensation under our 2014 Non-Employee Director Deferred Compensation Plan. Cash amounts deferred can be invested in deemed investment options in which we credit the amount deferred plus any earnings from the chosen investment options. Investment options under the plan are generally the same as those offered under

28

Table of Contents

the Company's 401(k) Plan through Vanguard, except that, among other things, directors may not elect to invest in the BSC Stock Fund. Deferred cash amounts are payable, at the non-employee director's written election, in either a lump-sum or in annual installments after a director's separation from Board service or in a lump-sum on an earlier fixed date (each in accordance with the plan).

Director Stock Ownership Guidelines

Non-employee directors are required to hold a significant personal investment in the Company through their ownership of shares of our common stock. Our director stock ownership guidelines provide that each non-employee director should own shares with a value equal to at least five times the director annual cash retainer (currently $90,000) within five years of his or her joining the Board. For purposes of satisfying this obligation, stock units and stock or stock unit deferrals under a Company deferred compensation plan may be included in the aggregate number of shares held by a director. We believe the stock ownership requirements for our non-employee directors align the interests of our directors with the long-term interests of our stockholders. All of our non-employee directors either currently meet our director stock ownership guidelines or we expect that they will meet the guidelines within five years of becoming a director. The Nominating and Governance Committee monitors compliance with these guidelines on an annual basis. For information regarding the stock ownership guidelines applicable to our Chief Executive Officer, please see the Compensation Discussion & Analysis section titled "Executive Stock Ownership Guidelines."

The table below summarizes the compensation we paid to our non-employee directors for the fiscal year ended December 31, 2016.

COMPENSATION DISCUSSION & ANALYSIS

This discussion and analysis describes material elements of our 2016 compensation program for our NEOs.

Under applicable SEC rules, we are required to disclose certain compensation and other information regarding our Chief Executive Officer, our Chief Financial Officer, and our three other most highly-compensated executive officers (referred to as our named executive officers or NEOs). Our named executive officers for the year ended December 31, 2016, are:

Company Strategic Imperatives and Select Business Results Linked to 2016 Executive Compensation

During 2016, we continued to focus on the five strategic imperatives we launched in 2013 to help drive innovation, accelerate profitable revenue growth and increase stockholder value:

•

Strengthen execution to grow share in our served markets.



•

Expand into high growth adjacencies that complement our core businesses.



•

Drive global expansion, including in emerging markets.



•

Fund the journey to fuel growth through optimization and cost reduction initiatives and a re-allocation of spending to support growth initiatives.



•

Develop key capabilities to enable delivery of economic- and customer-focused products and solutions aligned with marketplace needs.

With respect to our performance in 2016 relative to the financial performance metrics used in our short- and long-term incentive programs, we:

•

Generated GAAP (as defined below) net sales of $8.386 billion and net sales on a constant currency basis (SFX net sales) of $9.076 billion.



•

Reported GAAP net income per share of $0.25 and adjusted net income per share (adjusted EPS) of $1.11.



•

Generated GAAP cash flow from operating activities of $972 million and adjusted free cash flow of $1.607 billion.

SFX net sales, adjusted EPS and adjusted free cash flow are not prepared in accordance with generally accepted accounting principles in the United States (GAAP). For a reconciliation of these non-GAAP financial measures to the most directly comparable GAAP financial measures and insight into how these non-GAAP measures are considered by management, please see Annex A.

Pay for Performance

Our executive compensation philosophy is to provide appropriate competitive compensation opportunities to our executives with actual pay outcomes heavily influenced by achievement of Company and individual performance targets in support of our business strategy and creation of long-term stockholder value.

CEO's Realizable Total Direct Compensation Aligns with Company Performance

The following chart shows the value of the primary elements of total direct compensation (TDC), consisting of base salary and annual short- and long- term incentives, for our Chief Executive Officer in 2016 (i) at "target" opportunity as considered by our Compensation Committee; (ii) as disclosed in our Summary Compensation Table; and (iii) as "realizable" at December 31, 2016. These values were calculated using the 2016 base salary, annual equity incentives, and Annual Bonus Plan award amounts for our Chief Executive Officer as set forth in the footnotes to the chart below.

CEO Compensation
Target vs. Summary Compensation Table vs. Realizable

Amounts in the "Target" column consist of the following:

•

the annual equity awards granted on February 22, 2016, with (a) stock options valued in accordance with Financial Accounting Standards Board Accounting Standards Codification (FASB ASC) Topic 718, as described in the footnotes to the Executive Compensation section titled "Summary Compensation Table," and (b) service-based deferred stock

Table of Contents

units (DSUs) and performance-based DSUs valued at target (the number of units and target units awarded multiplied by the closing price of our common stock on the date of grant);

•

the target 2016 Annual Bonus Plan award; and

•

the annual base salary approved in February 2016.

Amounts in the "Summary Compensation Table" column consist of the following:

•

the annual equity awards granted on February 22, 2016, with the value of each award determined in accordance with FASB ASC Topic 718, as described in the footnotes to the Executive Compensation section titled "Summary Compensation Table";



•

the actual 2016 Annual Bonus Plan award; and



•

the annual base salary earned in 2016.

Amounts in the "Realizable" column consist of the following:

•

the annual equity awards granted on February 22, 2016, with (a) stock options valued at their intrinsic value (number of options awarded multiplied by the closing price of our common stock on December 31, 2016 less the exercise price of such options), (b) service-based DSUs valued using the number of units awarded multiplied by the closing price of our common stock on December 31, 2016, (c) Total Shareholder Return (TSR) performance-based DSUs valued using 165% of the target TSR performance-based DSUs due to the Company's TSR rank being tenth out of 54 in 2016 (165% of the target number of units multiplied by the closing price of our common stock on December 31, 2016), and (d) the free cash flow (FCF) performance-based DSUs valued using 114.2% of the target FCF performance-based DSUs (the actual percentage of target units earned under the program) multiplied by the closing price of our common stock on December 31, 2016;

•

the actual 2016 Annual Bonus Plan award; and

•

the annual base salary earned in 2016.

The significant difference in value of the long-term incentive compensation portion of our Chief Executive Officer's TDC reflected in the "Realizable" column of the chart above relative to the values reflected in the "Target" and "Summary Compensation Table" columns is primarily due to:

•

the increase in the closing price of our common stock on December 30, 2016 ($21.63) compared to the closing price of our common stock on February 22, 2016 ($17.26), the date of grant for the 2016 annual equity awards;



•

the 2016 TSR performance-based DSUs being valued at 165% of target as a result of the Company's TSR performance in 2016 relative to that of the other companies in the S&P 500 Healthcare Index (i.e., being ranked tenth out of 54 for the 2016 performance period); and



•

the 2016 FCF performance-based DSUs being valued at 114.2% of target as a result of the Company's FCF performance in 2016.

We believe that our CEO's "Realizable" TDC in light of the Company's stock price increase and TSR and FCF performance during 2016 demonstrates the alignment of our CEO's pay with Company performance and the long-term interests of our stockholders.

A Significant Portion of our NEOs' 2016 Target TDC is At-Risk, Performance-Based Compensation

Our Compensation Committee ties a significant portion of the primary elements of our executives' target TDC to at-risk, performance-based incentive opportunities. For 2016, 84% of the target value of

Table of Contents

the primary elements of TDC for our NEOs as a group (including our CEO) consisted of at-risk, performance-based incentive compensation, which was comprised of the following:

•

15% Short-Term Cash Incentive Awards, with:



Ø

Funding of the Total Bonus Pool tied to Company performance measured against adjusted EPS and SFX net sales performance targets.



Ø

Allocation of the Total Bonus Pool, as funded, based on business and functional performance measured against their respective financial and/or operational performance targets.



Ø

Actual payout adjusted based on each individual's performance.



•

69% Long-Term Equity Incentive Awards, with mix of opportunity comprised of:



Ø

25% Company performance-based deferred stock units (DSUs), a percentage of which is earned based on the total shareholder return (TSR) of our common stock relative to that of the other companies in the S&P 500 Healthcare Index over a three-year performance period.



Ø

25% Company performance-based DSUs, a percentage of which is earned based on our adjusted free cash flow (FCF) measured against our target performance over a one-year performance period and subject to service-based vesting over a three-year period (inclusive of the performance period).



Ø

25% stock options, with ultimate value tied to the performance of our stock price.



Ø

25% service-based DSUs, with ultimate value tied to the performance of our stock price.

The percentages above were calculated using the 2016 base salary, target equity values and target Annual Bonus Plan award amounts for our NEOs set forth in the footnote to the charts below. The allocation of the target value of the primary elements of TDC for our Chief Executive Officer and for our other NEOs as a group in 2016 was as follows:

Table of Contents

We believe our emphasis on at-risk, performance-based incentive compensation — consisting of our Annual Bonus Plan awards and long-term equity awards — aligns our executives with our business strategy and the short- and long-term interests of our stockholders, providing "pay for performance" and putting a significant portion of our executives' pay "at risk."

Executive Compensation Program Best Practices

Our Compensation Committee believes that a strong foundation for our compensation program is necessary to execute our executive compensation philosophy effectively. The following key aspects of executive compensation best practices serve as the foundation for our compensation program:

ü

Use a mix of short- and long-term incentive compensation, with an emphasis on long-term compensation.



ü

Use a mix of fixed and variable compensation, with an emphasis on variable, at-risk performance-based compensation.



ü

Require a "double-trigger" (both a change in control and termination without cause or for good reason) for cash payments and accelerated vesting of equity awards where the surviving or acquiring entity substitutes or assumes outstanding equity awards.



ü

Do not provide income tax gross-ups (except on relocation benefits).



ü

Do not provide any excise tax gross-ups on severance or other payments in the event of a change in control.



ü

Maintain stock ownership guidelines for our executives and directors.



ü

Have a policy for the recovery, commonly referred to as a "claw-back," of all or a portion of certain incentive compensation awards under certain circumstances.



ü

Use internal pay equity analysis.



ü

Use peer group company comparative analysis.



ü

Engage an independent compensation consultant reporting directly to the Compensation Committee.



ü

Perform risk assessment of incentive compensation policies and programs.



ü

Do not pay dividend equivalents on unvested performance-based DSUs or service-based DSUs.



ü

Do not permit repricing of underwater stock options without stockholder approval.



ü

Prohibit pledging or hedging of the economic value of our common stock by our executives and directors.

In connection with its review of our compensation program against our executive compensation philosophy and business objectives, our Compensation Committee took into consideration the modifications it had already made in prior years to our compensation programs in support of our executive compensation philosophy and best practices, the results of the say-on-pay advisory vote, as well as feedback the Company received on the matter from its stockholders in prior years. As a result, our Compensation Committee concluded that it would retain our compensation program's emphasis on at-risk, performance-based incentive compensation.

Executive Compensation Philosophy and Objectives

Our executive compensation philosophy is to provide appropriate competitive compensation opportunities to our executives with actual pay outcomes heavily influenced by achievement of Company, business and individual performance targets/objectives in support of our business strategy and creation of long-term stockholder value. The core objectives of our compensation program are to:

•

Attract, retain, and engage top talent.



•

Reinforce our culture of quality.



•

Align management's interests with the long-term interests of our stockholders.



•

Incentivize achievement of key Company, business and individual targets/objectives to support our business strategy.



•

Appropriately manage compensation risk in light of our business strategy.

Our Compensation Committee evaluates executive compensation best practices and makes modifications to our compensation program that it determines are appropriate to support our executive compensation philosophy.

Competitive Market Analysis

Our Compensation Committee considers executive compensation comparative data of our peer group companies in order to facilitate an understanding of trends and comparative practices in executive compensation generally, as well as with respect to the specific levels and mix of target compensation opportunities provided to our executives and program design in the market within which we compete for top talent. Our peer group includes companies (i) generally focused on a comparable industry (customer base and product offerings) such as pharmaceuticals, biotechnology & life sciences, and healthcare equipment & services companies, and (ii) that generally have a comparable size (0.5x to 2x) in relation to one or both of our revenue and market capitalization. Additional characteristics used to evaluate our peer companies may include being listed in three or more of our comparable companies' peer groups and being in the healthcare equipment industry.

Table of Contents

Our Compensation Committee reviews the composition and appropriateness of our peer group companies for executive compensation comparative purposes annually. Following a review in February 2016, our Compensation Committee approved the removal of Hospira, Inc., in light of its acquisition by Pfizer. Our 2016 peer group companies are listed below. At the time of review, our revenue and market capitalization were within the guidelines for our peer group companies set forth in the preceding paragraph.

For 2016, general industry survey data was also used for executive compensation comparative purposes for positions where sufficient peer group proxy data was not available. When making its determinations, the Compensation Committee was not aware of the constituent companies used in the general industry survey.

Internal Pay Equity and Other Considerations

Our Compensation Committee considers the primary elements of each executive's TDC opportunity compared to that of our other executives as well as the economic and retentive value of prior equity awards received by our executives in determining their current and future compensation.

Risk Considerations

Our Compensation Committee considers whether our executive compensation program is appropriately aligned with business risk by examining the potential effects that elements of our executive compensation program may have on such business risk. This includes, among other things, the mix of fixed and variable compensation; the mix of short- and long-term compensation; the mix of long-term equity incentives; mix of performance metrics, weighting, measurement, and payout timing; discretion and caps on short-term incentives; award size, vesting schedules and performance and other terms of long-term equity incentives; and other incentive opportunities and their features. Our Compensation Committee also considers mitigating design elements, including among other things, our recovery of incentive compensation awards policy and other recovery and forfeiture provisions relating to incentive compensation awards and other benefits, executive stock ownership guidelines, and hedging/pledging prohibition. For more details on these policies and guidelines, please see "Recovery of Incentive Compensation Awards Policy and Provisions," "Executive Stock Ownership Guidelines" and "Prohibition on Pledging and Hedging the Economic Value of our Common Stock". For more information about our assessment of compensation policies and practices as they relate to our risk management, please see "Risk Assessment of our Compensation Programs".

Performance Considerations

We utilize a performance, development and coaching (PDC) process to help guide individual development and performance discussions and assess annual performance. With respect to each of our executives that report directly to him, our Chief Executive Officer undertakes his or her annual PDC reviews, assesses his or her performance results and makes related compensation recommendations to our Compensation Committee for its consideration. Our Compensation Committee reviews our Chief Executive Officer's performance objectives and oversees the evaluation of our Chief Executive Officer's performance in relation to those objectives. For 2016, the overall performance of our executives,

47

Table of Contents

including our NEOs, was rated on a 3-point scale designed to support a culture of high performance and accountability with clear expectations. This scale consisted of "outstanding," "successful" and "improvement required." These performance achievement indicators, among the other considerations reviewed in this discussion and analysis, influence our executives' base salaries, the individual component of their Annual Bonus Plan awards and, as an indication of future performance potential, their long-term equity incentive awards.

Chief Executive Officer and Compensation Committee Judgment

The application of Chief Executive Officer and Compensation Committee judgment is an important factor in setting and determining executive pay. We do not employ a purely formulaic approach to our executive compensation program. Target market guidelines and individual target TDC, financial and operational targets, individual performance objectives and funding formulae are established in advance; however, other Company and individual performance and other considerations (such as budgets, costs to the Company, our quality objectives, changes in executive roles or responsibilities and current economic conditions) may also be taken into account. For example, while the funding formula tied to Company-level financial performance targets are set in advance under our Annual Bonus Plan, our Compensation Committee is able to reduce the Total Bonus Pool funding percentage (to not less than 50% of the target) based on its assessment of the Company's progress toward achievement of our quality objectives.

Participants in the Compensation Process

Our Compensation Committee bears principal responsibility for, among other things, structuring our executive compensation program and making individual executive compensation determinations. To help facilitate informed determinations with respect to its responsibilities, our Compensation Committee engages an independent compensation consultant, Frederic W. Cook & Co. (FW Cook), which serves at the direction and under the supervision of our Compensation Committee. For further information about our Compensation Committee and its composition, processes and responsibilities and about the services provided by FW Cook, please see the Meetings and Board Committees section titled "Executive Compensation and Human Resources Committee." FW Cook and certain members of management support our Compensation Committee with respect to the following, among other things:

Primary Elements of Total Direct Compensation

We compensate our executives primarily through total direct compensation, namely in the form of base salary and short- and long-term incentives (the primary elements of TDC). Our primary elements of TDC are heavily weighted towards variable, at-risk performance-based elements, which are reflected in the charts under the section above titled "A Significant Portion of our NEOs' 2016 Target TDC is At-Risk, Performance-Based Compensation." For 2016, only 16% of the target value of the primary elements of TDC for our NEOs as a group (including our CEO) consisted of fixed compensation in the form of base salary, while variable, at-risk performance-based compensation accounted for the remaining 84% of the primary elements of TDC. These percentages were calculated using the 2016 base salary, target equity values and target Annual Bonus Plan award amounts for our NEOs set forth in the footnotes to the charts under the section titled "A Significant Portion of our NEOs' 2016 Target TDC is At-Risk, Performance-Based Compensation."

The key features and objectives of the primary elements of our NEOs' 2016 TDC are summarized in the table below.

While our Compensation Committee considers the median market position relative to our peer group companies for comparable positions, individual target opportunities may vary based on our Compensation Committee's consideration of other factors, including those discussed under "How We Determine Executive Compensation." The target value of the primary elements of the TDC for our NEOs as a group for 2016 was below the market median. The primary elements of NEO TDC for 2016 is discussed below and reported in the Executive Compensation section titled "Summary Compensation Table" under the Salary, Stock Awards, Option Awards and Non-Equity Incentive Plan Compensation columns.

Table of Contents

Base Salary

In setting base salaries for our executives, our Compensation Committee generally considers their market position relative to our peer group companies' executives with comparable positions and scope of responsibilities, our annual merit-increase budget, our performance for the prior year, the executive's experience and scope of responsibilities, internal pay equity relative to other executives and the executive's performance evaluation under the prior year's PDC process.

2016 NEO Base Salaries

In determining the 2016 base salaries of our NEOs (other than our Chief Executive Officer), our Compensation Committee also considered the recommendations of our Chief Executive Officer in light of the general factors discussed above, including their overall performance ratings for the prior year — with Messrs. Brennan, Fitzgerald and Pratt successfully meeting the high expectations of each of them for 2016 and Mr. Ballinger delivering outstanding performance for 2016. In addition to the merit increases, with respect to Messrs. Brennan and Ballinger, the Compensation Committee included a market adjustment based on their market position relative to our peer group companies' executives with comparable positions and scope of responsibilities in determining the total increases of their base salaries from 2015 to 2016. In determining the 2016 base salary of Mr. Mahoney, our Compensation Committee considered the general factors discussed above, including his delivering outstanding performance for 2016 as our President and Chief Executive Officer.

The 2016 base salaries (rounded to the nearest thousand) of our NEOs as well as the percentage increase from their 2015 base salaries are set forth below:

Short-Term Incentives

Our Compensation Committee annually reviews the design of our Annual Bonus Plan to help ensure that the program continues to support our executive compensation philosophy and core compensation program objectives. In finalizing the design for 2016, our Compensation Committee retained the provisions of our 2015 Annual Bonus Plan, which was designed to reinforce the concept of "pay for performance," align our short-term incentives with important financial and operational measures and the long-term interests of our stockholders, and to incentivize and reward individual performance.

Total Bonus Pool Funded Based on Company Performance

Under the 2016 Annual Bonus Plan, a single Company-wide Total Bonus Pool is funded by the Company's performance measured against important Company-level financial performance metric targets, thereby reinforcing the importance of the Company's performance as a whole (which reflects the performance of our regions, businesses and functions). For 2016, our Compensation Committee:

•

Selected adjusted EPS and SFX net sales as our Company-level financial performance metrics, which measures were used to set important Company financial and operational performance goals for the year.

50

---

Table of Contents

•

Set Company performance level targets for those metrics at $1.04 and $8.735 billion, respectively.

For a description of how we calculate these non-GAAP financial measures as well as a reconciliation of these measures to the most directly comparable GAAP measures and insight into how these non-GAAP measures are considered by management, please see the Executive Compensation section titled "Narrative Disclosure to Summary Compensation Table and Grants of Plan-Based Awards Table — 2016 Annual Bonus Plan" and Annex A, respectively.

In February 2016, our Compensation Committee approved the Total Bonus Pool funding scale for the Company's 2016 performance measured against our 2016 Company-level performance metric targets for adjusted EPS and SFX net sales set forth in the table below. Each metric has a 50% weighting.

 

However, in order to reinforce the importance of "top line" growth to the Company, Total Bonus Pool funding is capped at 90% in the event that the Company's SFX net sales are below 97% of target. In addition, our Compensation Committee has the discretion to decrease the Total Bonus Pool funding percentage (to not less than 50% of the target) based on its assessment of the Company's performance relative to our quality objectives. For 2016, our quality objectives related to our quality culture, training, audits, reporting, compliance environment, and quality systems operations. Our Compensation Committee considers quality objectives to be appropriate in emphasizing our commitment to continually improving and sustaining our quality systems, our quality compliance and product performance, thereby enhancing stockholder value.

For 2016, based on our adjusted EPS of $1.11 per share and SFX net sales of $9.076 billion, we achieved 106.7% of the target level for adjusted EPS (in the range of 105%+ of target, which correlates to a bonus range of 125% to 150%) and 103.9% of the target level for SFX net sales (in the range of 103%+ of target, which correlates to a bonus range of 130% to 150%). Accordingly, the funding range for our 2016 Total Bonus Pool was between 127.5% and 150%. In accordance with the terms of the plan and after taking into consideration the Company's overall 2016 financial performance and performance against quality objectives, our Chief Executive Officer recommended, and our Compensation Committee approved, funding the 2016 Total Bonus Pool at 130%.

Funded Total Bonus Pool Allocated to Participating Units

Under the 2016 Annual Bonus Plan, the Total Bonus Pool, as funded, is allocated by the Compensation Committee to each participating regional, business, and functional unit taking into consideration our Chief Executive Officer's recommendations in light of that participating unit's performance measured

51

---

Table of Contents

against its operational and/or financial performance metric targets (and other factors the Compensation Committee deems appropriate), thereby incentivizing and rewarding each participating unit's performance contributions. Our NEOs received their 2016 Annual Bonus Plan awards from the allocation of the funded Total Bonus Pool to our Interventional Cardiology unit (Mr. Ballinger), Rhythm Management unit (Mr. Fitzgerald), and to our corporate function unit (all other NEOs). For 2016:

•

Due to Interventional Cardiology's overall performance measured against SFX net sales, adjusted operating income and constant currency growth compared to market targets coinciding with the business's operating plan for the year, the performance percentage for Interventional Cardiology was 140%.



•

Due to Rhythm Management's overall performance measured against SFX net sales, adjusted operating income and constant currency growth compared to market targets coinciding with the business's operating plan for the year, the performance percentage for Rhythm Management was 105%.



•

Due to the Company's overall performance, the performance percentage for the corporate funding unit was 130%, consistent with the 2016 Total Bonus Pool funding.

The Company does not disclose the specific targets for business, regional and functional participating units' performance metrics as they are highly confidential. Disclosing such confidential information would provide competitors and third parties with insight into the Company's internal planning processes that may allow them to predict certain of our business-, region- or function-specific financial or operational strategies, which could cause us competitive harm. Business and regional unit targets related to SFX net sales, adjusted operating income and constant currency growth compared to market are established in support of Company-wide targets such as sales, operating income, earnings per share and growth. These are based on a range of factors, including growth outlooks for our product portfolio, the competitive environment, our internal budgets, external market economic conditions and market expectations. For example, growth rates implicit in targets for any one business or regional unit may be above or below the growth rates targeted for the entire Company, due to faster or slower growth in relevant markets or smaller or larger market shares. These considerations result in business and regional unit targets that are intended to coincide with Company-wide targets in their level of difficulty to achieve and probability for success. Performance targets are set at levels that the Company believes are aggressive enough to inspire top performance but reasonable enough to be achievable through the efficient and diligent execution of their operating plans.

Individual Target Incentive Award Opportunity

Each executive's target incentive award opportunity under the Annual Bonus Plan is expressed as a percentage of his or her annual base salary and is determined based on the scope of the executive's responsibilities. For 2016, our Compensation Committee maintained the target award opportunities for Messrs. Brennan, Fitzgerald and Pratt at their 2015 levels of 70%, 70% and 80%, respectively, of their base salaries. In setting Mr. Mahoney's target award opportunity at 150% of his base salary, our Compensation Committee considered his market position relative to our peer group companies' executives with comparable positions and scope of responsibilities, internal pay equity relative to our other executives and his experience. In setting Mr. Ballinger's target award opportunity at 60% of his base salary, our Compensation Committee considered the recommendations of our Chief Executive Officer, internal pay equity relative to our other executives and his experience.

Individual Performance Component

After year end, individual performance is considered pursuant to the PDC process described in the "Performance Considerations" section. Based on the performance assessment rating under our annual PDC process, an individual performance percentage from 0% to 200% is applied as a multiplier to an executive's funded Annual Bonus Plan award to determine the actual amount to be paid. Under our 2016 Annual Bonus Plan, a rating of (i) "outstanding" generally permits an individual performance percentage of at least 115%, (ii) "successful" generally permits an individual performance percentage between 90% and 105%, and (iii) "improvement required" generally permits an individual performance percentage between 0% and 75%.

Our NEOs had certain performance objectives intended to support our strategic imperatives, as applicable to their roles, including (i) with respect to our NEOs who support corporate functions, those aimed at driving Company-level financial performance objectives, and (ii) with respect to Messrs. Ballinger and Fitzgerald, who each supports a business, those aimed at supporting business-level financial and operational performance objectives. The individual performance objectives discussed below do not represent objective performance goals that must be achieved but rather factors that may be considered by the Compensation Committee and our Chief Executive Officer in determining each NEO's individual performance percentage. Further, no single factor is determinative or required to be considered.

For 2016, Mr. Mahoney's individual performance objectives also included driving regional, business and functional performance, as well as strengthening overall company culture and developing our people and our leadership pipeline. Mr. Mahoney's individual performance percentage was 115% due primarily to his overall outstanding performance for 2016, with notable performance in accelerating our growth, diversifying our product portfolio, improving margin and ensuring a healthy leadership pipeline to meet our talent needs. Accordingly, his 2016 Annual Bonus Plan award was 149.5% of his target award.

For 2016, Mr. Brennan's individual performance objectives also included driving performance for the functional units over which he has responsibility, including achieving financial goals and cost-savings, as well as objectives aimed at supporting strategic transactions, strengthening relationships with investors and credit rating agencies, and resolving certain tax matters. Mr. Brennan's individual performance percentage was 100% due primarily to his overall performance successfully meeting the high expectations of him for 2016, with notable performance driving disciplined focus on financial performance, including implementing cost-savings initiatives, executing the financing process to support strategic acquisitions, and continuing to strengthen relationships with investors and credit rating agencies. Accordingly, his 2016 Annual Bonus Plan award was 130% of his target award.

For 2016, Mr. Ballinger's individual performance objectives also included driving business performance for Interventional Cardiology, achieving key product milestones, effectively executing product launches and other objectives related to enhancing organizational capabilities. Mr. Ballinger's individual performance percentage was 115% due primarily to his overall outstanding performance for 2016, with notable performance driving Interventional Cardiology's operating income results and executing on the global launch of the SYNERGY™ Everolimus-Eluting Platinum Chromium Coronary Stent System. Accordingly, his 2016 Annual Bonus Plan award was 161% of his target award.

For 2016, Mr. Fitzgerald's individual performance objectives also included driving business performance for Rhythm Management, achieving key product milestones, effectively executing product launches and other objectives related to enhancing organizational capabilities. Mr. Fitzgerald's individual performance percentage was 100% due primarily to his overall performance successfully

meeting the high expectations of him for 2016, with notable performance driving Rhythm Management's operating income results and executing on sales strategies for the Watchman™ Left Atrial Appendage Closure device. Accordingly, his 2016 Annual Bonus Plan award was 105% of his target award.

For 2016, Mr. Pratt's individual performance objectives also included driving performance for the functional units over which he has responsibility, including achieving cost savings and optimization initiatives, improving the structure and efficiency of Legal and Compliance, developing the culture within those functional units, managing and mitigating legal risk, and connecting with customers, government officials and business and regional leaders. Mr. Pratt's individual performance percentage was 100% due primarily to his overall performance successfully meeting the high expectations of him for 2016, with notable performance driving cost reductions, managing litigation risks, leading the advocacy efforts of the government affairs team, providing broad leadership across the Company and improving the structure and efficiency of Legal and Compliance. Accordingly, his 2016 Annual Bonus Plan award was 130% of his target award.

2016 Annual Bonus Plan Awards Paid to Our NEOs

After funding the Total Bonus Pool, the actual amount of an executive's Annual Bonus Plan award is ultimately determined by (i) multiplying the product of the executive's annual base salary for 2016 and his or her target award percentage by the executive's participating unit's performance percentage, and then (ii) multiplying the result of the foregoing by his or her individual performance percentage, as illustrated below:

Details regarding the short-term incentive awards paid to our NEOs under our 2016 Annual Bonus Plan are set forth in the table below.

Long-Term Incentives

Our Compensation Committee annually reviews the design of our Long-Term Incentive Program (LTI Program) to help ensure that the program continues to support our executive compensation philosophy and core compensation program objectives. In setting the design for 2016, our Compensation Committee retained the mix of equity award opportunities for our executives under our prior LTI Program that were designed to further reinforce "pay for performance" and align the

54

Table of Contents

interests of our executives and their compensation with important Company financial measures and the long-term interests of our stockholders. The key features and objectives of each type of equity vehicle included in the mix of equity awards comprising our NEOs' 2016 long-term equity incentive compensation are summarized in the table below.

2016 Long-Term Incentive Awards for Our NEOs

In setting long-term incentive award opportunities for our executives, our Compensation Committee generally considers their market position relative to our peer group companies' executives with comparable positions and scope of responsibilities, and their experience and scope of responsibilities.

In determining the 2016 long-term equity incentive award amounts for our NEOs, our Compensation Committee also considered the recommendations of the Chief Executive Officer in light of the general factors discussed above, including, as an indication of future performance potential, the executive's performance for the prior year determined under that year's PDC process.

In February 2016, our Compensation Committee approved the grant of long-term equity incentive awards to our NEOs in the following amounts, which were based on the target dollar values of the

57

Table of Contents

long-term equity incentive awards for our NEOs considered by the Compensation Committee (see discussion of such target dollar values below):

The target dollar values of the long-term equity incentive awards for our NEOs considered by our Compensation Committee in February 2016 were as follows: (i) $8.0 million for Mr. Mahoney; (ii) $2.0 million for Mr. Brennan; (iii) $1.3 million for Mr. Ballinger; (iv) $1.4 million for Mr. Fitzgerald; and (v) $1.2 million for Mr. Pratt. The target dollar values were then allocated in accordance with our LTI Program to 25% FCF performance-based DSUs, 25% TSR performance-based DSUs, 25% stock options and 25% service-based DSUs. The number of FCF and TSR performance-based DSUs and service-based DSUs were calculated by dividing the target dollar value of those awards by the closing price of our common stock on the date of grant, and the number of stock options was determined by dividing the target dollar value of that award by the stock option value determined in accordance with FASB ASC Topic 718, as described in the footnotes to the Executive Compensation section titled "Summary Compensation Table".

Company Performance-Based DSUs — Results for Performance Periods Ended December 31, 2016

In February 2017, our Compensation Committee determined the number of units earned pursuant to our performance-based DSUs under our 2014 TSR PSP and our 2016 FCF PSP.

Under the 2014 TSR PSP, our TSR performance rank was fourth relative to that of the other companies in the S&P 500 Healthcare Industry Index over the three-year performance period ended December 31, 2016. Accordingly, our Compensation Committee determined that pursuant to the terms of the program, 200% of the target number of TSR performance-based DSUs had been earned. As a result, the following numbers of shares of our common stock were delivered to our NEOs in settlement of the 2014 TSR performance-based DSUs awarded to them: (i) 290,518 shares for Mr. Mahoney; (ii) 57,338 shares for Mr. Brennan; (iii) 28,668 shares for Mr. Ballinger; (iv) 47,782 shares for Mr. Fitzgerald; and (v) 45,870 shares for Mr. Pratt.

Under the 2016 FCF PSP, our adjusted free cash flow performance over the one-year performance period ended December 31, 2016 was 107.1% relative to target performance. Accordingly, our Compensation Committee determined that pursuant to the terms of the program, 114.2% of the target number of FCF performance-based DSUs had been earned. As a result, and subject to the satisfaction of the service-vesting criteria, the following number of shares of our common stock will be delivered to our NEOs no later than January 15, 2019 in settlement of the 2016 FCF performance-based DSUs

awarded to them: (i) 132,328 shares for Mr. Mahoney; (ii) 33,081 shares for Mr. Brennan, (iii) 21,502 shares for Mr. Ballinger, (iv) 23,157 shares for Mr. Fitzgerald and (v) 19,849 shares for Mr. Pratt.

Primary Elements of Indirect Executive Compensation

We also compensate our executives, including our NEOs, using indirect compensation, namely in the form of benefits and limited perquisites. Generally, our benefits and perquisites are targeted to be competitive relative to our peer group companies. The primary elements of and objectives for our NEOs' 2016 indirect compensation are summarized below.

General Employee Benefits

We provide employee benefits to eligible employees, including our NEOs, to promote personal health and well-being and to provide certain financial security and protection upon retirement or in the event of death, disability or illness. As U.S.-based employees, our NEOs are eligible to receive employee benefits under our U.S. employee benefits program, which consists of the following key elements that are generally the same as those provided to our other U.S. salaried employees: (i) health and welfare benefits based primarily on a preferred provider model with executives sharing approximately 20% of the cost; (ii) Company-paid term life insurance policies that provide a benefit equal to base salary, with a minimum benefit of $50,000 and a maximum benefit of up to $1 million, payable upon death; and (iii) a qualified 401(k) retirement plan with a Company match of 6% of eligible salary up to $265,000 in 2016 resulting in a maximum possible match of $15,900. In addition, our executive officers may participate in an annual executive level physical examination program that is designed to encourage the proactive management of executive health. In approving the program, the Compensation Committee considered the overall cost of the program (estimated to be less than $10,000 per participant), that a majority of our peer group companies offered some form of benefit related to executive level annual physical examinations, and the importance of good health to an executive's ability to focus on the short and long-term needs of the Company. Company-paid term life insurance premium amounts (and related imputed income), Company matches of 401(k) Plan contributions for our NEOs, Company-paid executive level annual physical examination costs, and certain other reimbursements in 2016 are reported in the footnotes to the Executive Compensation section titled "Summary Compensation Table."

Deferred Compensation Programs

We maintain a Deferred Bonus Plan for certain of our management, including our NEOs, in order to provide them with the opportunity to defer up to 75% of their annual award under our Annual Bonus Plan until the earlier of termination of employment or an elected distribution date. In 2016, Messrs. Ballinger and Fitzgerald elected to defer 75% of their 2016 Annual Bonus Plan Award, which was paid in 2017, under the Deferred Bonus Plan. For additional discussion of the Deferred Bonus Plan, please see the narrative to the Executive Compensation section titled "Nonqualified Deferred Compensation."

Global Relocation Programs

We provide tiered relocation benefits under our global relocation program to eligible employees, including our NEOs, whom we request to move in connection with their current position or a promotion and for eligible new hires we require to move in connection with accepting a position with us. Our objectives in providing global relocation benefits are to attract and redeploy top talent. We provide "tax gross-ups" on applicable relocation benefits provided under our global relocation program as we believe that this benefit is integral to the Company's ability to attract and retain employees

59

whose skill or knowledge enhance the Company's competitive position. The U.S. executive tier of the program covers reasonable expenses associated with the move and certain relocation services to minimize the inconvenience and cost of moving, including as applicable, lump sum payments for temporary living, home search and miscellaneous expenses; new home search assistance; departure area home sales assistance; reimbursement of duplicative housing costs; moving household goods; reimbursement of final trip expenses to the new area; spousal/partner career assistance; and cost of living allowance for increases of at least eight percent in the cost of living from the previous residence location, paid as taxable income over four years in decreasing percentages. Under our global relocation program, participants are generally required to sign a reimbursement agreement that requires them to pay back expenses incurred by the Company for their relocation in the event that they voluntarily terminate their employment or are terminated for "cause" at a rate of 100% for termination within one year of the date on which payments were first made and 50% for termination following the first year but within two years of the date on which payments were first made.

Personal Use of Aircraft

Pursuant to Mr. Mahoney's offer letter, he is permitted reasonable personal use of our corporate aircraft up to $100,000 per year in aggregate incremental cost to the Company. Our other executives are permitted limited personal use of our corporate aircraft with prior approval. These executives are personally taxed on their personal use of our corporate aircraft and we do not provide them with income tax gross-up payments. The aggregate incremental cost to the Company (and disallowed tax deductions of the Company) for our NEOs' personal use of our corporate aircraft in 2016 is included in the footnotes to the Executive Compensation section titled "Summary Compensation Table."

Primary Elements of Post-Employment and Change in Control Arrangements

We provide post-employment and change in control payments and benefits to our executives under certain circumstances. We believe that offering our executives these payments and benefits facilitates the operation of our business, allows them to better focus their time, attention and capabilities on our business, and assists the Company in recruiting and retaining key executives. The primary elements of and objectives for our NEOs' 2016 post-employment and change in control agreements are summarized below.

Executive Retirement Plan

Our executives are eligible to participate in our Executive Retirement Plan. The objective of our Executive Retirement Plan is to provide a clear and consistent approach to managing retirement-eligible executive departures with a standard, mutually understood separation and post-employment relationship. The Executive Retirement Plan provides retiring executives with a lump sum benefit of 2.5 months of salary for each completed year of service, up to a maximum of 36 months' pay. The amount is payable in the first payroll period after the last day of the six-month period following retirement. Receipt of payment is conditioned upon the retiring executive entering into an agreement with the Company that includes a release of claims and customary non-disclosure, non-competition, non-solicitation and non-disparagement clauses in favor of the Company. To be eligible for benefits under the Executive Retirement Plan, an executive's age plus his or her years of service with the Company must total at least 65 years (provided that the executive is at least 55 years old and has been with the Company for at least five years). For further discussion of our Executive Retirement Plan, please see the narrative to the Executive Compensation section titled "Retirement Plan Benefits."

Severance Plans

We maintain severance plans for eligible employees, including our NEOs, under which participants are entitled to receive certain severance payments, subsidized COBRA health benefits and dental benefits for specified periods of time based on position level and classification and completed years of service to the Company and to receive outplacement services in the event of certain involuntary terminations. The payment of severance benefits under the plans is subject to the Company's receipt of a release of claims. Executives, including certain of our NEOs, who are eligible to receive payments under our Executive Retirement Plan or a Change in Control Agreement are not eligible to receive payments and benefits under our severance plans. For further discussion of our severance plans, please see the Executive Compensation section titled "Potential Payments Upon Termination or Change in Control — Severance Plans."

Change in Control Agreements

We provide Change in Control Agreements to our executives, including our NEOs, and other key employees. The possibility of a change in control and the uncertainty that it may raise among our executives as to their continued employment after or in connection with a change in control may result in their departure or distraction. Our objective in providing Change in Control Agreements is to retain and encourage the continued attention and dedication of our executives during a potentially critical time, even if they fear that their position will be eliminated after or in connection with the change in control. Our Change in Control Agreements require both a change in control and termination without cause or resignation for good reason within two years after the change in control event, commonly referred to as a "double-trigger," for cash payments to be made under the agreement and vesting to be accelerated under the agreement for equity awards where the surviving or acquiring entity substitutes or assumes outstanding equity awards. Our Change in Control Agreements include a release of claims as well as customary non-disclosure and non-solicitation clauses in favor of the Company. Executives, including our NEOs, who are eligible to receive payments under our Change in Control Agreements are not eligible to receive payments and benefits under our Executive Retirement Plan or our severance plans. For further discussion of our Change in Control Agreements, please see the Executive Compensation section titled "Potential Payments Upon Termination or Change in Control — Change in Control Agreements." Potential payments to our NEOs under our Change in Control Agreements are included in the tables in the Executive Compensation section titled "Potential Payments Upon Termination or Change in Control."

For a discussion of our other plans and arrangements under which a change in control and/or termination of employment triggers payments or benefits, please see the Executive Compensation section titled "Potential Payments Upon Termination or Change in Control." Potential payments to our NEOs as of December 31, 2016 under such plans or arrangements are included in the tables in the Executive Compensation section titled "Potential Payments Upon Termination or Change in Control."

In February 2007, our Compensation Committee adopted a policy regarding the recovery or adjustment of short-term incentive awards paid to an executive after the policy was adopted in the event relevant Company performance measures are restated in a manner that would have reduced the size of a previously granted award. In such an event, and to the extent permitted by applicable law, the Company would seek to recover the amount of the short-term incentive award paid to such executive that was in excess of the amount that would have been awarded based on the restated financial results, subject to and in accordance with the terms of the policy. Our Compensation

Committee monitors regulatory developments with respect to applicable executive compensation recovery policies required by the Dodd-Frank Wall Street Reform and Consumer Protection Act and it expects to consider such changes to the Company's current recovery policy as are necessary to comply with final rules (and related guidance, if any) to be issued by the SEC in accordance with such act.

In May 2013, our Compensation Committee adopted a policy regarding the recovery of certain short-and long-term incentive compensation awards paid or granted to an executive after the policy was adopted in the event of executive misconduct or gross dereliction of duty that resulted in a material violation of Company policy and caused significant harm to the Company. In such an event, and to the extent permitted by applicable law, the Company may seek reimbursement of all or a portion of cash incentive compensation awards paid within a certain time period and/or recovery of all or a portion of equity incentive awards granted to such executive over which the Company retains control, subject to and in accordance with the terms of the policy.

For a discussion of other recovery and forfeiture provisions relating to incentive compensation awards and other benefits provided to our executives, please see the section titled "Global Relocation Program" above, and the Executive Compensation sections titled "Retirement Plan Benefits" and "Narrative Disclosure to Summary Compensation Table and Grants of Plan-Based Awards Table."

Our executives are required to have a significant personal investment in the Company through their ownership of shares of our common stock. Effective January 1, 2016, our Board set new minimum stock ownership guidelines for executives, including our NEOs, as a number of shares of Company stock equal in value to at least the following amounts:

•

Chief Executive Officer: six times annual base salary; and



•

All other Executives: three times annual base salary.

Executives are required to comply with the guidelines at all times. However, if at any time an executive's ownership does not meet or exceed the guideline, he or she is expected to retain ownership of at least fifty percent of his or her net share ownership with respect to each vesting of an equity award or stock option exercise until the guideline is met or exceeded. For purposes of satisfying the guidelines, shares owned outright, shares held in company benefit plans and the intrinsic value of vested "in-the-money" stock options are included in the aggregate number of shares held by an executive. Unvested equity award shares (including service-based DSUs and performance-based DSUs) and unvested stock options are not included in the aggregate number of shares held by an executive. The Nominating and Governance Committee monitors compliance with these guidelines on an annual basis. As of December 31, 2016, our Chief Executive Officer and other NEOs were in compliance with these guidelines.

Our executives, including our NEOs and our directors are prohibited from speculating in the Company's securities, engaging in transactions designed to "hedge" the value of our common stock, and pledging their common stock as collateral for a loan. Executives and directors appointed after December 31, 2010 must unwind pre-existing hedging or pledging arrangements within nine months of their election or appointment. Pre-existing hedging or pledging arrangements of such executives and

directors will be disclosed at the time of their election or appointment in the Company's related Form 8-K.

In 2009, the Company eliminated tax gross-ups for its executives except for relocation benefits, which the Compensation Committee retained because the benefit generally applies to all employees eligible to receive relocation benefits, including our executives, and the Compensation Committee believes it is integral to the Company's ability to attract and redeploy employees whose skill or knowledge enhance the Company's competitive position. None of our NEOs received relocation benefits in 2016.

Under our Equity Award Grant Policy, grants of equity awards to our executives are approved and effective as follows:

•

Annual equity awards (if any) for our employees, including our executives, are generally approved by our Compensation Committee at a regularly scheduled meeting. Such awards are effective on the date of approval.



•

New hire, promotion, retention and other special or ad hoc awards for our executive officers are generally approved by our Compensation Committee. New hire or promotion awards for executive officers are effective on the first trading day of the month following both the date of hire or promotion and the date of approval. Retention and other special or ad hoc awards for our executive officers are effective on the first trading day of the month following approval.



•

Stock options are granted with an exercise price equal to the closing price of our common stock on the date of grant.

Section 162(m) of the Internal Revenue Code generally disallows a tax deduction to public companies for compensation over $1 million paid to a company's chief executive officer and the three other most highly compensated executive officers, other than the chief financial officer, employed by the company at the end of the year. Qualifying performance-based compensation is not subject to the deduction limit if certain requirements are met. Although we have plans that are intended to permit the award of deductible compensation under Section 162(m) of the Internal Revenue Code, our Compensation Committee does not necessarily limit executive compensation to the amount deductible thereunder.

The Company accounts for stock-based compensation in accordance with FASB ASC Topic 718, which requires the Company to recognize compensation expense for share-based payments (including stock options and other forms of equity compensation). FASB ASC Topic 718 is taken into account by the Compensation Committee in determining to use a portfolio approach to equity grants, awarding both stock options and DSUs.

RISK ASSESSMENT OF OUR COMPENSATION PROGRAMS

With the assistance of the senior members of our Global Compensation and Benefits organization, certain senior executive officers and the Compensation Committee's independent compensation consultant, FW Cook, in November 2016 the Compensation Committee reviewed a risk assessment of our compensation programs and policies to determine if the provisions and operations of our programs create undesired or unintentional risk of a material nature.

Our risk assessment included two work streams — one focused on reviewing areas of enterprise risk and the other focused on identifying compensation design risk. Our enterprise risk analysis examined the types and magnitudes of risks our business areas present to the Company. Our compensation design risk analysis examined the potential risks in the design of our performance-based incentive compensation arrangements. As part of this assessment, we analyzed the mix of fixed and variable compensation; the mix of short- and long-term compensation; the mix of long-term equity incentives; performance metric mix; weighting, measurement, and payout timing; discretion and caps on short-term incentives; award size, vesting schedules and performance and other terms of long-term equity incentives; and other incentive opportunities and their features. We also analyzed our recovery of incentive awards policy, executive stock ownership guidelines and hedging and pledging prohibitions. Finally, we evaluated on a combined basis the results of the enterprise and compensation risk assessments, on a business area-by-business area basis.

As a result of our analysis, the Compensation Committee believes that our compensation programs do not create risks that are reasonably likely to have a material adverse effect on the Company.

The following provides information about the terms of our 2016 Annual Bonus Plan, 2016 Performance Share Programs and our Long-Term Incentive Plan, pursuant to which our NEOs were awarded short- and long-term incentive compensation, as applicable and detailed in the tables above. For additional information regarding the application of these plans and programs to our NEOs in 2016, please see the Compensation Discussion & Analysis.

2016 Annual Bonus Plan

Our 2016 Annual Bonus Plan is administered by our Compensation Committee and was established under our 2011 LTIP. The plan year for our 2016 Annual Bonus Plan ran from January 1, 2016 to December 31, 2016. Generally all U.S. salaried employees not eligible for commissions under sales compensation plans and certain international and expatriate/inpatriate employees selected for participation are eligible to participate in our 2016 Annual Bonus Plan, provided they have at least two full months of service during the plan year. Participants generally must be employed with us on the date payments are made in order to receive awards under the plan. However, in the event of death or retirement or certain involuntary terminations without cause, in each case, as described in the 2016 Annual Bonus Plan, participants may receive their performance incentive awards for the year on a prorated basis based on the percentage of the year the participant was employed by us and eligible to participate. Participants who have at least two months of eligibility but less than a full year similarly may receive awards under the 2016 Annual Bonus Plan on a prorated basis.

Target Incentive Award Opportunity

Each participant is provided with a target incentive award opportunity under the 2016 Annual Bonus Plan expressed as a percentage of his or her base salary. For a discussion of the 2016 target incentive award opportunities for our NEOs, please see the Compensation Discussion & Analysis sections titled "Individual Target Incentive Award Opportunity" and "2016 Annual Bonus Plan Awards Paid to Our NEOs."

Company Performance Funds Total Bonus Pool

Company Performance Metrics and Weighting. Under the 2016 Annual Bonus Plan, after year-end a single Company-wide annual bonus pool (Total Bonus Pool) is funded based on the Company's performance measured against important Company-level financial performance metric targets. For 2016, our Compensation Committee selected adjusted EPS and standard foreign exchange (SFX) net sales as our Company-level performance metrics. Each metric has a 50% weighting.

69

---

Table of Contents

Company Metrics Defined. For purposes of our 2016 Annual Bonus Plan: (i) adjusted EPS equals adjusted net income (loss) divided by weighted average diluted shares outstanding for the performance year (adjusted net income equals GAAP net income (loss) excluding intangible asset impairment charges, acquisition-related net charges, restructuring and restructuring-related net charges, litigation-related net charges, pension termination charges, debt extinguishment charges, discrete tax items, and amortization expense, which are considered non-operational); and (ii) SFX net sales is calculated at an assumed standard constant currency basis that excludes the impact of changes in foreign currency rates, which are highly variable and difficult to predict.

For a discussion of the Company level targets under the 2016 Annual Bonus Plan, funding of the Total Bonus Pool and the individual performance component of the 2016 Annual Bonus Plan, please see the Compensation Discussion & Analysis section titled "Short-Term Incentives."

Recovery of Annual Bonus Plan Award

Our 2016 Annual Bonus Plan provides that, to the extent permitted by applicable law, our Board will seek reimbursement of incentive compensation paid to any executive officer under the plan in the event of a restatement of our financial results that reduced a previously granted award's size or payment. Under such circumstances, and to the extent permitted by applicable law, we would seek to recover the amount of the 2016 Annual Bonus Plan award paid to such executive that was in excess of the amount that would have been paid based on the restated financial results. Additionally, our 2016 Annual Bonus Plan provides that, to the extent permitted by applicable law, our Board may seek reimbursement of incentive compensation paid to an executive under the plan in the event of executive misconduct or gross dereliction of duty that resulted in a material violation of Company policy and caused significant harm to the Company. In such an event, and to the extent permitted by applicable law, the Board may seek reimbursement of all or a portion of cash incentive compensation awards paid within a certain time period under the plan.

2016 Total Shareholder Return Performance Share Program

Our 2016 TSR PSP is administered, and the TSR performance-based DSUs awarded pursuant to our 2016 TSR PSP are granted, under our 2011 LTIP. The TSR performance-based DSUs vest upon the satisfaction of both the Company performance criteria and service criteria under the 2016 TSR PSP, subject to acceleration in the event of certain qualifying terminations discussed below. Our executives, including our NEOs, are eligible to participate in the 2016 TSR PSP, which is administered by our Compensation Committee. For a discussion of the TSR performance-based DSUs awarded to our NEOs in 2016, please see the Compensation Discussion & Analysis section titled "2016 Long-Term Incentive Awards for our NEOs."

Company Performance Criteria

For a discussion of the Company performance criteria under the 2016 TSR PSP please see the Compensation Discussion & Analysis section titled "Long-Term Incentives."

Calculation of TSR and Percentile Performance. The TSR for the Company and each other company in the S&P 500 Healthcare Index for the three-year performance period is determined based on the following formula:

(Change in Stock Price + Dividends Paid) / Beginning Stock Price

70

---

Table of Contents

The change in stock price is determined by subtracting the beginning stock price (the daily average closing price of one share of common stock for the two calendar months prior to the beginning of the performance period) from the ending stock price (the daily average closing price of one share of common stock for the last two calendar months of the performance period). The dividends paid are the total of all cash dividends paid on one share of common stock during the performance period.

Following the calculation of the TSR for the three-year performance period for our Company and each of the other companies in the S&P 500 Healthcare Index, the companies will be ranked in order of maximum to minimum TSRs for the full three-year performance period. Our percentile performance will be determined by (i) dividing (a) our ranking versus that of the other companies in the S&P 500 Healthcare Index minus one, by (b) the total number of companies in the S&P 500 Healthcare Index minus one, and (ii) subtracting the result from one.

Service Criteria

Generally under the 2016 TSR PSP, except with respect to termination of employment due to retirement, death or disability, or in connection with a change in control, in each case, as described in the 2016 TSR PSP and/or the 2011 LTIP, a participant must be employed with us on December 31, 2018 to be eligible to receive shares of our common stock in respect of his or her TSR performance-based DSUs as to which the performance criteria under the program have been satisfied.

For information regarding potential payments upon certain terminations of employment or in connection with a change in control, please see "Potential Payments Upon Termination or Change in Control."

2016 Free Cash Flow Performance Share Program

Our 2016 FCF PSP is administered, and the FCF performance-based DSUs awarded pursuant to our 2016 FCF PSP are granted, under our 2011 LTIP. The 2016 grants of FCF performance-based DSUs vest upon the satisfaction of both the one-year Company performance criteria and the three-year service criteria (inclusive of the performance period) under the 2016 FCF PSP, subject to acceleration in the event of certain qualifying terminations discussed below. Our executives, including our NEOs, were eligible to participate under the 2016 FCF PSP, which is administered by our Compensation Committee. For a discussion of the 2016 FCF performance-based DSUs awarded to our NEOs and the Company's achievement of the Company performance criteria under the program, please see the Compensation Discussion & Analysis section titled "2016 Long-Term Incentive Awards for our NEOs."

2011 Long-Term Incentive Plan

The purpose of the broad-based equity incentive award opportunities available for grant under our 2011 LTIP is to attract, retain, engage and focus key employees and other eligible participants on achieving long-term stockholder value by rewarding them for the increased performance of our common stock underlying such awards. Our 2011 LTIP is administered by our Compensation Committee and provides for the grant of restricted or unrestricted common stock, deferred stock units, options to acquire our common stock, stock appreciation rights (SARs), performance awards and other stock and non-stock awards (collectively, Awards). Our 2011 LTIP prohibits repricing or replacement of options or SARs and the issuance of in-the-money options or SARs, and includes limitations on the amounts of grants and payments to any individual within a given fiscal year as well as certain other customary limitations. Employees, directors and other individuals who provide services to us and our affiliates who, in the opinion of the Compensation Committee, are in a position to make a significant contribution to our success or that of our affiliates are eligible for Awards under our 2011 LTIP. Our 2011 LTIP became effective on June 1, 2011, following its approval at our 2011 Annual Meeting of Stockholders, and will terminate on March 1, 2021 (unless terminated sooner by our Board), and no further Awards may be granted following that date.

Certain Separations from Service

Generally under the 2011 LTIP, except with respect to termination of employment due to retirement, death or disability, or in connection with a change in control, in each case, as described therein or as otherwise provided for in the applicable award agreement, all equity awards terminate to the extent not vested immediately prior to the cessation of employment, and to the extent vested but not exercised at such time, remain exercisable for the lesser of one year or until the expiration of the stated term of the award. Further, in the event of a termination for "cause" (defined as conviction of, or a failure to contest prosecution for, a felony, or misconduct or dishonesty that is harmful to our business or reputation), or as a result of reasons that cast such discredit on the individual as to justify immediate termination of the award, in each case, as determined in the Compensation Committee's sole discretion, all outstanding equity awards (including unexercised stock options, whether vested or unvested) terminate immediately upon notice of such termination.

For a discussion of our plans and arrangements under which a change in control and/or termination of employment triggers payments or benefits, including our 2011 LTIP, please see the narrative to the tables appearing in "Potential Payments Upon Termination or Change in Control." Potential payments to our NEOs in 2016 under such plans or arrangements are included in the tables appearing in "Potential Payments Upon Termination or Change in Control."

2016 Equity Awards

With respect to our executives, including our NEOs as applicable, our Compensation Committee set the mix of equity award opportunities under our 2016 Long-Term Incentive Program at 25% target TSR performance-based DSUs, 25% target FCF performance-based DSUs, 25% stock options and 25% service-based DSUs. For a discussion of the 2016 equity awards made to our NEOs, please see the Compensation Discussion & Analysis section titled "Long-Term Incentives."

All of our executive officers, including our NEOs, are eligible to participate in our Executive Retirement Plan, as amended effective November 1, 2014. The Executive Retirement Plan is intended to provide a clear and consistent approach to managing retirement-eligible executive departures with a standard, mutually understood separation and post-employment relationship. The plan provides retiring executives with a lump sum benefit of 2.5 months of salary for each year of service, up to a maximum of 36 months' pay. The lump sum payments are made in the first payroll period after the last day of the six-month period following retirement. Receipt of payment is conditioned upon the retiring employee entering into a separation agreement with us that includes a release of claims and customary non-disclosure, non-competition, non-solicitation and non-disparagement clauses in favor of the Company. The plan provides that in the event the executive breaches the non-competition or non-solicitation provision of his or her separation agreement, the executive must, in addition to any other court-ordered relief, repay to the Company all amounts paid under the plan.

To receive benefits under the plan, upon his or her retirement an executive's age plus his or her years of service with us must total at least 65 years (provided that the executive is at least 55 years old and has been employed by us for at least five years). For purposes of the plan, "retirement" means any separation from service (as defined in the plan) other than a termination for "cause" (defined as conviction of, or failure to contest prosecution for, a felony, or misconduct or dishonesty that is harmful to our business or reputation). In addition, if an executive dies and is otherwise eligible for benefits under the plan on the date of his or her death, benefits under the plan will be paid within 60 days of the executive's death.

The Executive Retirement Plan includes a special participant eligibility classification for employees that are "Grandfathered Individuals." Under the Executive Retirement Plan, an employee is a Grandfathered Individual if (i) he or she has completed at least 10 continuous years of service with the Company prior to retiring, (ii) immediately prior to retiring he or she is serving in a "Special Assignment," which is a regular position of employment with the Company that he or she assumed, at the written request of the Chief Executive Officer or his or her designee, immediately after serving for a period of at least five consecutive years as a member of the Company's executive committee and/or in a division president position not on the executive committee, and (iii) the Compensation Committee approved the inclusion of the employee in an eligibility classification as a Grandfathered Individual in connection with his or her acceptance of the Special Assignment.

If a Grandfathered Individual satisfies the requirements to receive benefits under the Plan, he or she will receive a lump sum benefit payable in the first payroll period after the last day of the six-month period following his or her retirement. In the case of a Grandfathered Individual that served as a member of the Company's executive committee during the entire five-year period immediately prior to assuming the Special Assignment, the lump sum benefit will be equal to 2.5 months of salary for each year of service, up to a maximum of 36 months' pay. For a Grandfathered Individual that did not serve as a member of the Company's executive committee during the entire five-year period immediately prior to assuming the Special Assignment, the lump sum benefit will be equal to 1.5 months of salary for each year of service, up to a maximum of 24 months' pay. The base salary used for purposes of calculating the lump sum benefit will be the greater of the Grandfathered Individual's base salary immediately prior to retirement or his or her base salary immediately prior to assuming the Special Assignment.

For retirement-eligible NEOs (Mr. Pratt), the present value of accrued benefits is calculated as the value of their lump sum benefit under the plan based on the NEO's base salary, age and number of

77

Table of Contents

years of credited service as of December 31, 2016. For NEOs who were not eligible for retirement (Messrs. Mahoney, Brennan, Ballinger and Fitzgerald) as of December 31, 2016, the present value of accrued benefits is calculated based on the respective NEO's base salary, age and number of years of credited service as of December 31, 2016, discounted to December 31, 2016 from the earliest retirement eligibility date, using a discount rate of 3.5% per year. This valuation methodology is consistent with the methodology we use for financial statement accounting purposes except that executives are assumed to remain employed by us until their earliest retirement age under the plan (or their age on December 31, if eligible for retirement at that date). For financial statement accounting purposes, the valuation considers the probability that the executives will achieve retirement age. For a more detailed description of the assumptions used in valuing accrued benefits under the plan, please see Note A — Significant Accounting Policies to our 2016 consolidated financial statements included in Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2016.

The table below shows the present value of accumulated benefits payable to each of our NEOs, including the numbers of years of service credited to each NEO, under our Executive Retirement Plan as of December 31, 2016.

In May 2010, our Board approved the Boston Scientific Corporation Deferred Bonus Plan (the Deferred Bonus Plan). The Deferred Bonus Plan provides certain of our management, including our NEOs, an opportunity to defer a portion of their annual award under our Annual Bonus Plan. The Deferred Bonus Plan provides participants the opportunity to defer up to 75% of their annual award under our Annual Bonus Plan until the earlier of (i) termination of employment or (ii) an elected distribution date, such election to be made by June 30th of each year. Investment choices under the plan are generally the same as those under our 401(k) Retirement Savings Plan, except that, among other things, participants may not elect to invest in the BSC Stock Fund. Distributions under the plan are in either lump sum payments or annual installments over a period of two to five years, as specified by the participant. Under the Deferred Bonus Plan, Mr. Mahoney elected to defer 35% of his 2014 Annual Bonus Plan Award, Mr. Fitzgerald elected to defer 50% of his 2014 and 2015 Annual Bonus Plan Awards and 75% of his 2016 Annual Bonus Plan Award, and Mr. Ballinger elected to defer 75% of his 2016 Annual Bonus Plan Award.

In September 2004, we committed to fund a special one-time contribution to our 401(k) Retirement Savings Plan for the benefit of our employees. In June 2005, we adopted an Excess Benefit Plan, a non-qualified deferred compensation plan designed to provide specific supplemental benefits to those

78

Table of Contents

employees who would have exceeded the 2004 Internal Revenue Code contribution limits if the special contribution had been made to their 401(k) plan accounts. Accordingly, the historic Excess Benefit Plan was established to accept the "overflow" contributions resulting from the special one-time contribution on behalf of participating employees, including certain of our NEOs. Investment choices under the historic Excess Benefit Plan are generally the same as those under our 401(k) Retirement Savings Plan, except that, among other things, executive officers may not elect to invest in the BSC Stock Fund. The investment elections are made by each participant and may be changed daily. Generally, a lump sum cash payment of their respective account balances under the plan is made to participants determined to be "specified employees," including certain of our NEOs, commencing no earlier than six months and one day following their "separation from service."

The table below shows the aggregate earnings and balances for each of our NEOs under our historic Excess Benefit Plan and Deferred Bonus Plan as of December 31, 2016.

The investment choices under the historic Excess Benefit Plan and the Deferred Bonus Plan and their annual rates of return for the year ended December 31, 2016 are contained in the following table.

All of our executives, including our NEOs, are eligible to participate in our Executive Retirement Plan. The Executive Retirement Plan is intended to provide a clear and consistent approach to managing executive departures with a standard mutually-understood separation and post-employment relationship. The benefits payable to our executives upon "retirement" under the Executive Retirement Plan, as well as the present value of amounts accrued thereunder as of December 31, 2016, are reflected in the table and the related footnotes and narrative to the section titled "Retirement Plan Benefits." In addition, changes in the present value of the benefits under the Executive Retirement Plan from December 31, 2015 to December 31, 2016 are reflected in the "Change in Pension Value and Nonqualified Deferred Compensation Earnings" column of the Summary Compensation Table. For further discussion of our Executive Retirement Plan, please see the narrative to the table appearing in the section titled "Retirement Plan Benefits."

Change in Control Agreements

We provide Change in Control Agreements to our executives, including our NEOs, and other key employees. Our Change in Control Agreements for our executives are limited to a three-year term and provide that if both a change in control occurs during the term of the agreement and the executive's employment is terminated either by us without "Cause" or by the executive for "Good Reason" (each as described below) during the two-year period following the change in control, then the executive would be entitled to receive a lump sum payment of three times the sum of (i) the executive's base salary and (ii) target incentive bonus (or prior year's bonus, if higher). Additionally, an executive would be entitled to receive a prorated target incentive bonus for the year in which his or her termination occurred, continuation of health, life insurance and other welfare benefits for up to three years, and reimbursement for up to $100,000 in legal fees and expenses incurred by an executive in disputing termination or enforcing rights under his or her Change in Control Agreement. Our Change in Control Agreements further provide that all equity granted to executives require both a change in control and a termination without Cause or resignation by the executive for Good Reason within two years after the change in control in order to accelerate vesting; provided, however, that if the surviving or acquiring entity in a change in control transaction does not provide for the substitution or assumption of outstanding equity awards, such outstanding awards will immediately become fully vested.

The Change in Control Agreements do not include an excise tax "gross-up" but rather require a reduction in the amount of the severance payments if the reduction would result in a greater after-tax amount. In exchange for the benefits afforded under our Change in Control Agreements, our executives agree to certain non-disclosure restrictions, a two-year non-solicitation obligation and to execute a release in favor of the Company. Executives, including our NEOs, who are eligible to receive payments under our Change in Control Agreements are not also eligible to receive payments and benefits under our Executive Retirement Plan or Severance Plan For Exempt Employees (the Severance Plan).

For purposes of our Change in Control Agreements, "Cause" generally means willfully engaging in criminal or fraudulent acts or gross misconduct that is demonstrably and materially injurious to us. "Good Reason" generally means, among other things, assignment of duties inconsistent with the executive's status as an executive or an adverse alteration of the executive's duties; a reduction in annual base salary or bonus or failure to increase salary at a rate commensurate with that of other key executives; an adverse change in long-term incentive opportunities; failure by the Company to

continue to provide comparable benefits or continue in effect, or continue the executive's participation in, any compensation plan in which the executive participates; the relocation of the executive's principal place of work more than 50 miles; or failure by the Company to obtain a satisfactory agreement from any successor entity to agree to perform the Change in Control Agreement.

Long-Term Incentive Plan

Our employees, including our NEOs, are eligible to receive equity awards under our 2011 LTIP. Equity awards granted to our executives under our 2011 LTIP require both a change in control and a subsequent termination without Cause or for Good Reason pursuant to the terms of our Change in Control Agreements for accelerated vesting where the surviving or acquiring entity assumes outstanding awards.

Further, beginning in July 2010, the terms of all annual equity awards granted to our employees, including our NEOs, provide that in the event that the employee's employment terminates due to disability or retirement (each as defined in the 2011 LTIP) prior to the first anniversary of the equity award grant date, the unvested equity award will immediately lapse and be forfeited, and in the event of a termination due to death prior to the first anniversary of the equity award grant date, a prorated portion of such awards will vest based on the percent of the year completed prior to death. In the event of a termination due to disability, retirement or death after the first anniversary of the equity award grant date, all unvested equity awards will vest in full.

Our 2011 LTIP is more fully described under the section titled "Narrative Disclosure to Summary Compensation Table and Grants of Plan-Based Awards Table — 2011 Long-Term Incentive Plan."

TSR Performance Share Programs

Our TSR PSPs cover our executives, including our NEOs, and are administered by the Compensation Committee. Under our TSR PSPs, if a participant's employment terminates due to retirement, death or disability after December 31 in the year of grant, but prior to the end of the three-year performance period, shares of our common stock will be issued in respect of the TSR performance-based DSUs as to which the performance criteria under the program have been satisfied at the end of the three-year performance period, on a prorated basis. However, such awards will be forfeited in their entirety in the event retirement, death, or disability occurs prior to December 31 in the year of grant.

Pursuant to the terms of our Change in Control Agreements, the TSR performance-based DSUs awarded to our executives require both a change in control and a subsequent termination without Cause or for Good Reason for accelerated vesting where the surviving or acquiring entity assumes outstanding awards. Under our TSR PSPs and our Change in Control Agreements, if a change in control and a subsequent termination without Cause or for Good Reason occurs after December 31 in the year of grant, but prior to the end of the three-year performance period, shares of our common stock will be issued in respect of the TSR performance-based DSUs as to which the performance criteria under the program have been satisfied on the last day of the month preceding the date on which the change in control is consummated, on a prorated basis. However, such awards will be forfeited in their entirety in the event a change of control occurs prior to December 31 in the year of grant.

Our 2016 TSR PSP is more fully described under the section titled "Narrative Disclosure to Summary Compensation Table and Grants of Plan-Based Awards Table — 2016 Total Shareholder Return Performance Share Program."

Table of Contents

FCF Performance Share Programs

Our FCF PSPs cover our executives, including our NEOs, and are administered by our Compensation Committee. Under our FCF PSPs, if a participant's employment terminates due to retirement, death or disability after the end of the one-year performance period but prior to the end of the three-year service period, shares of our common stock will be issued in respect of the FCF performance-based DSUs as to which the performance criteria under the program have been satisfied on a prorated basis. Pursuant to the terms of our Change in Control Agreements, the FCF performance-based DSUs awarded to our executives require both a change in control and a subsequent termination without Cause or for Good Reason for accelerated vesting where the surviving or acquiring entity assumes outstanding awards. However, such awards will be forfeited in their entirety in the event of a change of control that occurs prior to the end of the one-year performance period.

Our 2016 FCF PSP is more fully described under the section titled "Narrative Disclosure to Summary Compensation Table and Grants of Plan-Based Awards Table — 2016 Free Cash Flow Performance Share Program."

2016 Annual Bonus Plan

Our 2016 Annual Bonus Plan is generally available to all U.S. salaried personnel not eligible for commissions under sales compensation plans, including our NEOs, and certain international and expatriate/inpatriate employees working in positions designated by the Company as eligible to participate in the plan. To be eligible to receive their incentive award, participants generally must be employed by us on the date payments are made under the 2016 Annual Bonus Plan. However, in the event of death, retirement or certain involuntary terminations without cause, in each case, as described in the 2016 Annual Bonus Plan, participants may receive their performance incentive awards for the year on a prorated basis based on the percentage of the year the participant was employed by us and eligible to participate (subject to certain minimum months of service requirements). Grants of performance incentive awards to our NEOs under our 2016 Annual Bonus Plan are reflected in the Summary Compensation Table in the "Non-Equity Incentive Plan Compensation" column, and our 2016 Annual Bonus Plan is more fully described under the section titled "Narrative Disclosure to Summary Compensation Table and Grants of Plan-Based Awards Table — 2016 Annual Bonus Plan", as well as the Compensation Discussion & Analysis section titled "Short-Term Incentives."

Severance Plans

We maintain severance plans for eligible employees, including our NEOs, under which participants are entitled to receive certain payments and benefits for specified periods of time following a qualifying termination. Such benefits are only available in the event of certain involuntary terminations either (i) due to an anticipated facility relocation or closing or a reduction of staffing levels where the employee has not refused a similar position with us, or (ii) resulting from a sale, merger or reorganization of our Company where the employee is not provided an opportunity to be employed in a similar position with the acquiring or resulting entity. Executives, including our NEOs, who are eligible to receive payments under our Executive Retirement Plan, are not also eligible to receive payments and benefits under our severance plans. In addition, executives who receive severance payments under a Change in Control Agreement are not eligible to receive payments and benefits under our severance plans.

The Severance Plan provides that director level and above exempt employees, including certain of our NEOs, are eligible for (i) two weeks of payments for each completed year of service to the Company, based on the weekly rate of the employee's salary in effect on the date of his termination, with a

82

Table of Contents

minimum benefit of 26 weeks and a maximum benefit of 52 weeks, (ii) one month of subsidized health and dental coverage for each completed year of service to the Company with a minimum benefit of six months and a maximum benefit of twelve months, and (iii) outplacement services, in each case, in the event of certain involuntary terminations described above.

Additionally, the Severance Plan provides that in the event of certain involuntary terminations, employees eligible to participate in our Annual Bonus Plan may be entitled to a prorated bonus if such involuntary termination occurs on or after October 1 of a calendar year. The prorated bonus is calculated by multiplying the amount of the bonus an employee would have received for the calendar year, had he or she remained employed by the Company until the bonus payment date (or, if less, the target bonus) times a fraction, the denominator of which is the number of days in the calendar year, and the numerator of which is the number of days in which he or she was a bonus-eligible employee during the calendar year.

Under the Severance Plan, the payment of severance benefits is subject to the Company's receipt of a release of claims. In addition, the maximum severance payment available under the plan is limited to twice the Internal Revenue Code dollar limitation in effect for qualified plans for the calendar year immediately preceding the calendar year in which the termination occurs.

The following tables show potential payments to Messrs. Mahoney, Brennan, Ballinger, Fitzgerald and Pratt under existing agreements, plans or other arrangements, for various scenarios involving a change in control or termination of employment, in each case assuming the termination was effective before the end of the day on December 31, 2016 and, where applicable, using the closing market price of our common stock of $21.63 per share on December 30, 2016. In each case, amounts in these tables do not include amounts payable, if any, to our NEOs who were not retirement eligible on December 31, 2016 pursuant to our Executive Retirement Plan, which are described in the table and accompanying narrative and footnotes in the section titled "Retirement Plan Benefits."

PROPOSAL 2: ADVISORY VOTE TO APPROVE
NAMED EXECUTIVE OFFICER COMPENSATION

Section 14A of the Exchange Act requires that we provide our stockholders with the opportunity to vote to approve, on a non-binding, advisory basis, the compensation of our named executive officers as disclosed in this Proxy Statement in accordance with the compensation disclosure rules of the SEC. Our Board has determined to provide our stockholders this opportunity on an annual basis and we expect the next vote to be held at our 2018 annual meeting of stockholders.

As described in the Compensation Discussion & Analysis, our executive compensation philosophy is to provide appropriate competitive compensation opportunities to our executives with actual pay outcomes heavily influenced by the achievement of Company performance targets and individual performance objectives (in other words, "pay for performance") in support of our business strategy and creation of long-term stockholder value.

Executive Compensation Program Best Practices

Our Compensation Committee believes that a strong foundation for our compensation program is necessary to execute our executive compensation philosophy effectively. The following key aspects of executive compensation best practices serve as the foundation for our compensation program:

ü

Use a mix of short- and long-term incentive compensation, with an emphasis on long-term compensation.



ü

Use a mix of fixed and variable compensation, with an emphasis on variable, at-risk performance-based compensation.



ü

Require a "double-trigger" (both a change in control and termination without cause or for good reason) for cash payments and accelerated vesting of equity awards where the surviving or acquiring entity substitutes or assumes outstanding equity awards.



ü

Do not provide income tax gross-ups (except on relocation benefits).



ü

Do not provide any excise tax gross-ups on severance or other payments in the event of a change in control.



ü

Maintain stock ownership guidelines for our executives and directors.



ü

Have a policy for the recovery, commonly referred to as a "claw-back," of all or a portion of certain incentive compensation awards under certain circumstances.



ü

Use internal pay equity analysis.



ü

Use peer group company comparative analysis.



ü

Engage an independent compensation consultant reporting directly to the Compensation Committee.



ü

Perform risk assessment of incentive compensation policies and programs.

91

Table of Contents

ü

Do not pay dividend equivalents on unvested performance-based DSUs or service-based DSUs.



ü

Do not permit repricing of underwater stock options without stockholder approval.



ü

Prohibit pledging or hedging of the economic value of our common stock by our executives and directors.

Pay for Performance

We believe our emphasis on at-risk, performance-based incentive compensation — consisting of our Annual Bonus Plan awards and long-term equity awards — aligns our executives with our business strategy and the short- and long-term interests of our stockholders, providing "pay for performance" and putting a significant portion of our executives' pay "at risk."

A Significant Portion of our NEOs' 2016 Target TDC is At-Risk, Performance-Based Compensation

Our Compensation Committee ties a significant portion of the primary elements of our executives' target TDC to at-risk, performance-based incentive opportunities. For 2016, 84% of the target value of the primary elements of TDC for our NEOs as a group (including our CEO) consisted of at-risk, performance-based incentive compensation, which was comprised of the following:

•

15% Short-Term Cash Incentive Awards, with:



Ø

Funding of the Total Bonus Pool tied to Company performance measured against adjusted EPS and SFX net sales performance targets.



Ø

Allocation of the Total Bonus Pool, as funded, based on business and functional performance measured against their respective financial and/or operational performance targets.



Ø

Actual payout adjusted based on each individual's performance.



•

69% Long-Term Equity Incentive Awards, with mix of opportunity comprised of:



Ø

25% Company performance-based DSUs, a percentage of which is earned based on the TSR of our common stock relative to that of the other companies in the S&P 500 Healthcare Index over a three-year performance period.



Ø

25% performance-based DSUs, a percentage of which is earned based on our adjusted free cash flow measured against our target performance over a one-year performance period and subject to service-based vesting over a three-year period (inclusive of the performance period).



Ø

25% stock options, with ultimate value tied to the performance of our stock price.



Ø

25% service-based DSUs, with ultimate value tied to the performance of our stock price.

The percentages above were calculated using the 2016 base salary, target equity values and target Annual Bonus Plan award amounts for our NEOs set forth in the footnote to the chart below. The

92

Table of Contents

allocation of the target value of the primary elements of TDC for our NEOs as a group (including our CEO) in 2016 was as follows:

---

(1)		The chart reflects the value of the primary elements of 2016 TDC opportunity as considered by the Compensation Committee as follows: (i) the annual equity awards granted to our NEOs on February 22, 2016, with stock options valued in accordance with FASB ASC Topic 718, as described in the footnotes to the Executive Compensation section titled "Summary Compensation Table," and with both service-based DSUs and Company performance-based DSUs valued at target (using the number of units and target units awarded multiplied by the closing price of our common stock on the date of grant); (ii) the target Annual Bonus Plan awards; and (iii) the annual base salaries approved in February 2016.

For further discussion of the allocation of the target value of the primary elements of TDC for our Chief Executive Officer and for our other NEOs as a group in 2016, please see the Compensation Discussion & Analysis section titled "Pay for Performance."

Accordingly, we ask our stockholders to vote "FOR" the following resolution at the Annual Meeting:

"RESOLVED, that the Company's stockholders approve, on an advisory basis, the compensation of the named executive officers, as disclosed in the Company's Proxy Statement for the 2017 Annual Meeting of Stockholders pursuant to Item 402 of Regulation S-K, including the Compensation Discussion & Analysis, compensation tables and narrative discussion."

While the vote is advisory in nature, which means that it is non-binding on us, our Compensation Committee values the opinions of our stockholders and will take into consideration the outcome of the vote when considering future executive compensation arrangements.

OUR BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE "FOR" THE APPROVAL OF THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS AS DISCLOSED IN THIS PROXY STATEMENT PURSUANT TO ITEM 402 OF REGULATION S-K.

PROPOSAL 3: ADVISORY VOTE ON THE FREQUENCY OF AN ADVISORY
VOTE TO APPROVE NAMED EXECUTIVE OFFICER COMPENSATION

The Dodd-Frank Wall Street Reform and Consumer Protection Act, as well as the provisions of Section 14A of the Exchange Act, also requires that we provide our stockholders with the opportunity to vote to approve, on a non-binding advisory basis, how frequently we should seek future advisory votes to approve the compensation of our named executive officers as disclosed in our proxy statements pursuant to the SEC's compensation disclosure rules. By voting on this Proposal 3, our stockholders may indicate whether they would prefer an advisory vote to approve named executive officer compensation once every one year (annual basis), two years (biennial basis), or three years (triennial basis), or abstain from voting on this proposal.

We have determined that an annual advisory vote to approve named executive officer compensation will allow our stockholders to provide timely, direct input on the executive compensation of our named executive officers as disclosed in our proxy statement each year pursuant to the SEC's compensation disclosure rules. We believe that an annual advisory vote on executive compensation is consistent with the Company's willingness to engage in on-going dialogue with our stockholders on corporate governance matters and our executive compensation philosophy, policies and practices. Accordingly, we ask that our stockholders vote "FOR" an annual advisory vote on our executive compensation.

We recognize that our stockholders may have different views as to what is the most appropriate approach for the Company, and therefore stockholders may cast a vote on the preferred frequency of an advisory vote to approve our executive compensation by selecting the option of one year (annual), two years (biennial), three years (triennial) or abstain when voting in response to the resolution set forth below at the Annual Meeting:

"RESOLVED, that the option of every year (annual basis), two years (biennial basis) or three years (triennial basis) that receives the highest number of votes cast for this resolution will be determined to be the preferred frequency of the Company's stockholders, on an advisory basis, with which the Company holds an advisory vote on the compensation of our named executive officers as disclosed in our proxy statement pursuant to the Securities and Exchange Commission's compensation disclosure rules."

While the vote is advisory in nature, which means that it is non-binding on us, our Compensation Committee values the opinions of our stockholders and will take into consideration the outcome of the vote when considering the frequency of future advisory votes on our executive compensation.

OUR BOARD UNANIMOUSLY RECOMMENDS YOU VOTE "FOR" THE OPTION OF
ONCE EVERY YEAR AS THE FREQUENCY WITH WHICH OUR STOCKHOLDERS
WILL BE PROVIDED AN ADVISORY VOTE TO APPROVE OUR
NAMED EXECUTIVE OFFICER COMPENSATION.

AUDIT COMMITTEE REPORT

The Audit Committee oversees our Company's financial reporting process on behalf of the Board of Directors and has other responsibilities as set forth in the Audit Committee charter, which is available on our website at www.bostonscientific.com under the "Investor Relations" section. Management has the primary responsibility for our Company's financial statements and reporting process, including the systems of internal controls. Ernst & Young LLP (Ernst & Young), our independent registered public accounting firm for fiscal year 2016, is responsible for expressing an opinion on the conformity of our Company's audited financial statements with generally accepted accounting principles and on our Company's internal control over financial reporting.

In fulfilling its oversight responsibilities, the Audit Committee reviewed with management and Ernst & Young the audited financial statements included in the Boston Scientific Annual Report on Form 10-K for the year ended December 31, 2016, including a discussion about the quality, not just the acceptability, of our Company's accounting principles, the reasonableness of significant judgments, and the clarity of disclosures in the financial statements, and Ernst & Young's evaluation of the Company's internal control over financial reporting.

The Audit Committee also discussed with Ernst & Young the matters that are required to be discussed by Auditing Standard No. 16, Communications with Audit Committees. Ernst & Young has also provided the Audit Committee the written disclosures and the letter required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent registered public accounting firm's communications with the Audit Committee concerning independence, and the Audit Committee has discussed with Ernst & Young that firm's independence. The Audit Committee has concluded that Ernst & Young's provision of audit and non-audit services to the Company and its affiliates is compatible with Ernst & Young's independence.

The Audit Committee further discussed with the Company's internal auditors and Ernst & Young the overall scope and plans for their respective audits. The Audit Committee meets at least quarterly with the internal auditors and Ernst & Young, with and without management present, to discuss the results of their examinations, their evaluations of the Company's internal controls, and the overall quality of the Company's financial reporting.

Based on the reviews and discussions referred to above, the Audit Committee approved the inclusion of the audited financial statements in the Annual Report on Form 10-K for the year ended December 31, 2016, which has been filed with the Securities and Exchange Commission. The Audit Committee has also approved the selection of Ernst & Young as the Company's independent registered public accounting firm for fiscal year 2017.

This Audit Committee Report does not constitute soliciting material and should not be deemed filed or incorporated by reference into any other Boston Scientific filing with the SEC, except to the extent that Boston Scientific specifically incorporates this Report by reference into another Boston Scientific filing.

PROPOSAL 4: RATIFICATION OF APPOINTMENT OF INDEPENDENT
REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee of the Board has appointed Ernst & Young LLP as our independent registered public accounting firm for the 2017 fiscal year. The Audit Committee is directly responsible for the appointment, retention, compensation and oversight of the work of our independent registered public accounting firm (including resolution of disagreements between management and the independent registered public accounting firm regarding financial reporting) for the purpose of preparing or issuing an audit report or related work. In making its determination regarding whether to appoint or retain a particular independent registered public accounting firm, the Audit Committee takes into account the views of management and our internal auditors, and will take into account the vote of our stockholders with respect to the ratification of the selection of our independent registered public accounting firm.

Representatives of Ernst & Young LLP are expected to attend the Annual Meeting and respond to questions and, if they desire, make a statement.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE "FOR" THE RATIFICATION OF THE APPOINTMENT OF ERNST & YOUNG LLP AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE 2017 FISCAL YEAR.

Audit Committee's Pre-Approval Policy

It is the Audit Committee's policy to approve in advance the types and amounts of audit, audit-related, tax and any other services to be provided by our independent registered public accounting firm. In situations where it is not possible to obtain full Audit Committee approval, the Audit Committee has delegated authority to the Chairman of the Audit Committee to grant pre-approval of auditing, audit-related, tax and all other services. Any pre-approved decisions by the Chairman are required to be reviewed with the Audit Committee at its next scheduled meeting. The Audit Committee approved all of Ernst & Young LLP's services for 2015 and 2016 and, in doing so, considered whether the provision of such services is compatible with maintaining independence.

ANNEX A

Reconciliations of GAAP Financial Measures to Non-GAAP Financial Measures Used as
Performance Metrics Under Certain of Our Short- and Long-Term Incentive Compensation Plans and Programs

The following is a reconciliation of cash provided by operating activities prepared in accordance with generally accepted accounting principles in the United States (GAAP) to adjusted free cash flow as used in our 2016 Free Cash Flow Performance Share Program (2016 FCF PSP):

The following is a reconciliation of net sales prepared in accordance with GAAP to net sales on an assumed standard constant currency basis (SFX net sales) as used in our 2016 Annual Bonus Plan:

Table of Contents

The following is a reconciliation of earnings per share prepared in accordance with GAAP to adjusted earnings per share (adjusted EPS) as used in our 2016 Annual Bonus Plan:

Use of Non-GAAP Financial Measures

To supplement our consolidated financial statements presented on a GAAP basis, we disclose certain non-GAAP financial measures. These non-GAAP financial measures are not prepared in accordance with GAAP. Management uses non-GAAP financial measures to evaluate performance period over period, to analyze the underlying trends in our business, to assess our performance relative to our competitors, to assess our performance relative to our internal financial and operating plans, to execute our capital allocation strategy and/or to establish operational goals and forecasts that are used in allocating resources. In addition, management uses non-GAAP financial measures to further its understanding of the performance of our operating segments.

To describe the relationship between pay and performance, we disclose certain non-GAAP financial measures used as performance metrics under certain of our short- and long-term incentive compensation plans and programs, including SFX net sales, adjusted EPS and adjusted free cash flow. These non-GAAP financial measures are not prepared in accordance with GAAP.

Adjusted free cash flow as used in our 2016 FCF PSP excludes certain cash items included in cash flow from operating activities (the most-directly comparable GAAP financial measure) and includes certain cash items not included in cash flow from operating activities as these items are highly variable period to period, difficult to predict and/or we believe are not indicative of cash flow from operating activities. Accordingly, management excluded/included these cash items for purposes of reviewing our cash flow performance in calculating this non-GAAP financial measure under our 2016 FCF PSP to facilitate an evaluation of our cash flow performance relative to our internal financial plan in accordance with the program.

SFX net sales as used in our 2016 Annual Bonus Plan excludes the impact of changes in foreign currency exchange rates included in our net sales (the most directly comparable GAAP financial measure) as the impact of changes in foreign currency exchange rates is highly variable period to period and difficult to predict. Accordingly, management excluded the impact of changes in foreign currency exchange rates, through the use of a standard assumed constant currency rate, for purposes of reviewing our sales performance in calculating this non-GAAP financial measure under our 2016 Annual Bonus Plan to facilitate an evaluation of our performance relative to our operating plan in accordance with the Annual Bonus Plan.

These amounts are excluded by management in assessing our performance, as well as from our operating segments' measures of profit and loss used for assessing their performance. Accordingly, management excluded these items for purposes of reviewing our performance in calculating this non-GAAP financial measure under our 2016 Annual Bonus Plan to facilitate an evaluation of our performance relative to our internal financial plan in accordance with the Annual Bonus Plan.

We believe that presenting the non-GAAP financial measures that are used as performance metrics under certain of our short- and long-term incentive compensation plans and programs, in addition to the corresponding GAAP financial measures, provides investors greater transparency to information relevant to the relationship between pay and performance and allows investors to see our results "through the eyes" of management.
