QUESTIONS AND ANSWERS ABOUT THIS PROXY MATERIAL AND VOTING

Why am I receiving these materials?

        You have received these proxy materials because the Board of Directors (our "Board" or the "Board of Directors") of Boingo Wireless, Inc. ("we", "us" or the "Company") is soliciting your proxy to vote at the 2017 Annual Meeting.

Why did I receive a Notice of Internet Availability of Proxy Materials in the mail instead of a printed set of proxy materials?

        Pursuant to rules adopted by the Securities and Exchange Commission, we are permitted to furnish our proxy materials over the Internet to our stockholders by delivering a Notice in the mail. As a result, only stockholders that specifically request a printed copy of the proxy statement will receive one. Instead, the Notice instructs stockholders on how to access and review the proxy statement and annual report over the Internet at www.proxyvote.com. The Notice also instructs stockholders on how they may submit their proxy over the Internet. If a stockholder who received a Notice would like to receive a printed copy of our proxy materials, such stockholder should follow the instructions for requesting these materials contained in the Notice.

What am I voting on?

        There are four matters scheduled for a vote:

•

Election of three Class III directors.



•

Ratification of the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2017.



•

To approve an amendment to the Company's Certificate of Incorporation to declassify the Board of Directors and provide for the annual election of directors.



•

To approve, on an advisory basis, our Company's executive compensation for the year ended December 31, 2016 as disclosed herein.

Who can vote at the Annual Meeting?

        Only stockholders of record at the close of business on April 13, 2017 will be entitled to vote at the Annual Meeting. On this record date, there were [            ] shares of Company common stock ("Common Stock") outstanding. The holders of Common Stock have the right to one vote for each share they held as of the record date.

        In accordance with Delaware law, a list of stockholders entitled to vote at the meeting will be available at the place of the Annual Meeting on June 8, 2017 and will be accessible for ten days prior to the meeting at our principal place of business, 10960 Wilshire Blvd, 23rd Floor, Los Angeles, CA 90024, between the hours of 9:00 a.m. and 5:00 p.m. (Pacific Time).

How do I vote?

        If on April 13, 2017, your shares were registered directly in your name with our transfer agent, American Stock Transfer & Trust Company, then you are a stockholder of record. Stockholders of record may vote by using the Internet, by telephone or (if you received a proxy card by mail) by mail as described below. Stockholders also may attend the meeting and vote in person.

Internet voting is available 24 hours a day and will be accessible until 11:59 p.m. Eastern Time on June 7, 2017. Easy-to-follow instructions allow you to vote your shares and confirm that your instructions have been properly recorded.

Telephone voting is available 24 hours a day and will be accessible until 11:59 p.m. Eastern Time on June 7, 2017. Easy-to-follow voice prompts allow you to vote your shares and confirm that your instructions have been properly recorded.



•

You may vote by mail by requesting, completing and mailing in a paper proxy card, as outlined in the Notice. The method you use to vote will not limit your right to vote at the Annual Meeting if you decide to attend in person.

        Written ballots will be passed out to anyone who wants to vote at the Annual Meeting. If you hold your shares in "street name," you must obtain a proxy, executed in your favor, from the holder of record to be able to vote in person at the Annual Meeting.

What if I return a proxy card but do not make specific choices?

        If you return a signed and dated proxy card without marking any voting selections, your shares will be voted (i) "For" the election of all three of your Board's nominees for director, (ii) "For" ratification of the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2017, (iii) "For" the approval of an amendment to the Company's Certificate of Incorporation to declassify your Board and provide for the annual election of directors, and (iv) "For" the advisory approval of our Company's executive compensation for the year ended December 31, 2016 as disclosed herein. However, if you are not a record holder, such as where your shares are held through a broker, nominee, fiduciary or other custodian, you must provide voting instructions to the record holder of the shares in accordance with the record holder's requirements in order for your shares to be properly voted. If any other matter is properly presented at the meeting, your proxy (one of the individuals named on your proxy card) will vote your shares using his best judgment.

Who is paying for this proxy solicitation?

        We will pay for the entire cost of soliciting proxies. In addition to these mailed proxy materials, our directors and employees may also solicit proxies in person, by telephone, or by other means of communication. Directors and employees will not be paid any additional compensation for soliciting proxies. We may reimburse brokerage firms, banks and other agents for the cost of forwarding proxy materials to beneficial owners.

        In addition, we have hired Alliance Advisors, at an estimated cost of $15,000, plus reimbursement of reasonable expenses, to assist in the solicitation of proxies.

What does it mean if I receive more than one proxy card or Notice?

        If you receive more than one proxy card or Notice, your shares are registered in more than one name or are registered in different accounts. Please complete, sign and return each proxy card or submit a proxy for each Notice to ensure that all of your shares are voted.

Can I change my vote after submitting my proxy?

        Yes. You can revoke your proxy at any time before the final vote at the meeting. You may revoke your proxy in any one of three ways:

•

You may submit another properly completed proxy card with a later date.



•

You may send a written notice that you are revoking your proxy to the Secretary of the Company at 10960 Wilshire Boulevard, 23rd Floor, Los Angeles, California 90024.



•

You may attend the Annual Meeting and vote in person. Simply attending the meeting will not, by itself, revoke your proxy.

Who will solicit proxies on behalf of the board?

        Proxies may be solicited on behalf of our Board, without additional compensation, by the Company's directors and employees.

        In addition, we have hired Alliance Advisors, at an estimated cost of $15,000, plus reimbursement of reasonable expenses, to assist in the solicitation of proxies.

        The original solicitation of proxies by mail may be supplemented by telephone, telegram, facsimile, electronic mail, and personal solicitation by our directors and officers (who will receive no additional compensation for such solicitation activities). You may also be solicited by advertisements in periodicals, press releases issued by us and postings on our corporate website at www.boingo.com. Unless expressly indicated otherwise, information contained on our corporate website is not part of this proxy statement.

How are votes counted?

        Votes will be counted by the inspector of election appointed for the meeting, who will separately count "For" and "Against" votes, abstentions and broker non-votes. Abstentions will be counted as present for purposes of determining the presence of a quorum. For Proposal 1, abstentions will not be considered as votes cast for or against any director, and will therefore have no effect on the outcome of the vote. For Proposals 2, 3 and 4, abstentions will have the same effect as a vote against the proposal. Other than Proposal 3, broker non-votes, as described in the next paragraph, have no effect and will not be counted towards the vote total for such proposals. With respect to Proposal 3, broker non-votes will have the same effect as an "Against" vote.

        If your shares are held by your bank or broker as your nominee (that is, in "street name"), you will need to obtain a voting instruction form from the institution that holds your shares and follow the instructions included on that form regarding how to instruct your broker to vote your shares. If you do not give instructions to your broker, your broker can vote your shares with respect to "discretionary" items, but not with respect to "non-discretionary" items. Discretionary items are proposals considered routine under the rules of the New York Stock Exchange ("NYSE") on which your broker may vote shares held in street name without your voting instructions. On non-discretionary items for which you do not give your broker instructions, the shares will be treated as broker non-votes. Under current NYSE rules, any election of a member of the Board of Directors, whether contested or uncontested, is considered "non-discretionary" and therefore brokers are not permitted to vote your shares held in street name for the election of directors in the absence of instructions from you. All of our proposals, except for Proposal 2, are "non-discretionary" and therefore if you hold your shares through a broker, nominee, fiduciary or other custodian, your shares will not be voted on those proposals unless you provide voting instructions to the record holder

Table of Contents

How many votes are needed to approve each proposal?

•

For Proposal 1, directors, in an uncontested election, are elected by the vote of the majority of the votes cast with respect to such director. This means that the number of shares voted "FOR" a Class III candidate for election as director must exceed the number of votes cast "AGAINST" that director. Abstentions and broker non-votes are not considered votes cast on this proposal and will not have any effect on the election of directors.

We have also implemented a policy for director resignations, applicable if an incumbent director nominee receives less than a majority of votes cast in an uncontested election. For more information see "Proposal No. 1—Election of Directors" below. The Board of Directors recommends a vote "FOR" all nominees.

•

To be approved, Proposal 2, to ratify the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2017, must receive a "For" vote from the majority of all outstanding shares present in person or represented by proxy at the Annual Meeting and entitled to vote thereon either in person or by proxy. Therefore, abstentions are counted as present and therefore will have the same effect as a vote against the proposal.



•

To be approved, Proposal 3, an amendment to the Company's Certificate of Incorporation to declassify our Board and provide for the annual election of directors, must receive a "For" vote from holders of at least two-thirds of all outstanding shares of common stock of the Company entitled to vote generally in the election of directors, either in person or by proxy. If you "Abstain" from voting, it will have the same effect as an "Against" vote. Broker non-votes will also have the same effect as an "Against" vote.



•

To be approved, Proposal 4, advisory approval of our Company's executive compensation for the year ended December 31, 2016, must receive a "For" vote from the majority of all outstanding shares present in person or represented by proxy at the Annual Meeting and entitled to vote thereon either in person or by proxy. If you "Abstain" from voting, it will have the same effect as an "Against" vote. Broker non-votes will have no effect. However, the advisory approval of our Company's executive compensation for the year ended December 31, 2016 is advisory and non-binding in nature and cannot overrule any decisions made by our Board.

What is the quorum requirement?

        A quorum of stockholders is necessary to hold a valid meeting. A quorum will be present if a majority of all shares outstanding on April 13, 2017, the record date, are represented at the meeting by stockholders present in person or by proxy. On the record date, there were [            ] shares of Common Stock outstanding and entitled to vote. Thus [            ] shares must be represented by stockholders present at the meeting or by proxy to have a quorum.

        Your shares will be counted towards the quorum only if you submit a valid proxy vote or vote at the meeting. Abstentions and broker non-votes will be counted towards the quorum requirement.

How will my shares be voted if I mark "Abstain" on my proxy card?

        We will count a properly executed proxy card marked "Abstain" as present for purposes of determining whether a quorum is present, but the shares represented by that proxy card will not be voted at the Annual Meeting for the proposals so marked.

How can I find out the results of the voting at the Annual Meeting?

        Preliminary voting results will be announced at the Annual Meeting. Final voting results will be available on a Current Report on Form 8-K filed with the Securities and Exchange Commission within four business days after the end of the Annual Meeting.

When are stockholder proposals due for next year's Annual Meeting?

        If you wish to submit a proposal to be considered for inclusion in next year's proxy materials, your proposal must be in proper form according to SEC Regulation 14A, Rule 14a-8 and received by the Secretary of the Company on or before [            ]. If you wish to submit a proposal to be presented at the 2018 Annual Meeting of Stockholders, but which will not be included in the Company's proxy materials, including to nominate a director, your Solicitation Notice, as defined in our bylaws, must be received by the Secretary of the Company at Boingo Wireless, Inc., 10960 Wilshire Blvd, 23rd Floor, Los Angeles, CA 90024, Attn: Secretary, no earlier than February [            ], 2018 and no later than March [            ], 2018.

CORPORATE GOVERNANCE AND BOARD MATTERS

Independence of the Board of Directors

        As required under the listing standards of the Nasdaq Global Market ("Nasdaq"), a majority of the members of a Nasdaq-listed company's board of directors must qualify as "independent," as affirmatively determined by its board of directors. Our Board of Directors consults with counsel to ensure that the Board of Directors' determinations are consistent with all relevant laws and regulations regarding the definition of "independent," including those set forth in pertinent listing standards of Nasdaq, as in effect from time to time.

        Management and outside counsel have reviewed the directors' responses to a questionnaire asking about their transactions, relationships and arrangements with the Company (and those of their immediate family members) and other potential conflicts of interest. Other than as set forth in this proxy statement, these questionnaires did not disclose any transactions, relationships, or arrangements that question the independence of our directors or director nominees. After reviewing this information, our Board of Directors affirmatively determined that, except for David Hagan (our Chief Executive Officer), all of our directors are independent directors within the meaning of the applicable Nasdaq listing standards.

Information Regarding the Board of Directors and its Committees

        As required under Nasdaq listing standards, our independent directors meet in regularly scheduled executive sessions at which only independent directors are present. Charles Boesenberg, our lead independent director, presides over these executive sessions. During 2016, the Board had an Audit Committee, a Compensation Committee, a Nominating and Corporate Governance Committee, a

Compensation Committee of the Board of Directors during 2016 and David Cutrer was appointed to the Compensation Committee in June 2016. All members of the Compensation Committee are independent as currently defined under Nasdaq listing standards.

        The Compensation Committee met six times during 2016. Mr. Hagan, our principal executive officer, does not participate in the determination of his own compensation or the compensation of directors. However, he makes recommendations to the Compensation Committee regarding the amount and form of the compensation of the other executive officers and key employees, and he often participates in the Committee's deliberations about their compensation. Mr. Hovenier, our Chief Financial Officer, and Bethany Ellis, our Senior Vice President Human Resources, also assist the Committee in its executive officer, director and employee compensation deliberations. No other executive officers participate in the determination of the amount or form of the compensation of executive officers or directors.

        The Croner Company advised the Compensation Committee during 2015 and 2016 on executive compensation-related matters. The Compensation Committee has assessed the independence of The Croner Company pursuant to SEC rules and Nasdaq listing standards and determined that no impermissible conflict of interest exists that would prevent The Croner Company from independently representing the Compensation Committee.

Nominating and Corporate Governance Committee

        Our Nominating and Corporate Governance Committee is responsible for, among other things:

•

assisting our Board of Directors in identifying prospective director nominees and recommending nominees for each annual meeting of stockholders to the Board of Directors;



•

reviewing developments in corporate governance practices and developing and recommending governance principles applicable to our Board of Directors;



•

overseeing the evaluation of our Board of Directors and management;



•

recommending members for each Board committee to our Board of Directors;



•

reviewing and monitoring our code of business conduct and ethics; and



•

reviewing and evaluating, at least annually, its own performance and that of its members, including compliance with the committee charter and confirming the Company's compliance with applicable government regulations and corporate policies.

        Our Nominating and Corporate Governance Committee charter can be found on the corporate governance section of our corporate website at www.boingo.com. Each of Chuck Davis and Terrell Jones served on the Nominating and Corporate Governance Committee of the Board of Directors during 2016 and Kathy Misunas was appointed to the Nominating and Corporate Governance Committee in June 2016. All members of the Nominating and Corporate Governance Committee are independent as currently defined under Nasdaq listing standards. The Nominating and Corporate Governance Committee met nine times during 2016.

        Our Nominating and Corporate Governance Committee believes that the minimum qualifications and skills that candidates for director should possess include (a) the highest professional and personal ethics and values, (b) broad experience at the policy-making level in business, government, education, technology or public interest, (c) a commitment to enhancing stockholder value and (d) sufficient time to carry out their duties and to provide insight and practical wisdom based on experience. The committee also considers the following factors, in no particular order of importance: (a) various and relevant career experience, (b) relevant skills, such as an understanding of the Company's business,

15

---

Table of Contents

(c) financial expertise, (d) diversity and (e) local and community ties. However, the Nominating and Corporate Governance Committee retains the right to modify these qualifications from time to time.

        Candidates for director nominees are reviewed in the context of the current composition of our Board, our operating requirements and strategy and the long-term interests of our stockholders. While we do not have a formal policy on diversity, our Nominating and Corporate Governance Committee considers diversity of experience as one of the factors it considers in conducting its assessment of director nominees, along with such other factors as it deems appropriate given the then current needs of the Board and the Company, to maintain a balance of knowledge, experience and capability. In the case of incumbent directors, our Nominating and Corporate Governance Committee reviews such directors' overall service to the Company during their term, including the number of meetings attended, level of participation, quality of performance, and any other relationships and transactions that might impair such directors' independence. In the case of new director candidates, the committee also determines whether the nominee must be independent for Nasdaq purposes, which determination is based upon applicable Nasdaq listing standards, applicable SEC rules and regulations and the advice of counsel, if necessary.

        The Nominating and Corporate Governance Committee uses its network of contacts to compile a list of potential candidates, but may also engage, if it deems appropriate, a professional search firm. The Committee conducts any appropriate and necessary inquiries into the backgrounds and qualifications of possible candidates after considering the function and needs of the Board. The Committee meets to discuss and consider such candidates' qualifications and then selects a nominee for recommendation to the Board by majority vote.

        The Nominating and Corporate Governance Committee will consider director candidates recommended by stockholders and evaluate them using the same criteria as candidates identified by the Board or the Nominating and Corporate Governance Committee for consideration. If a stockholder of the Company wishes to recommend a director candidate for consideration by the Nominating and Corporate Governance Committee, the stockholder recommendation should be delivered to the Secretary of the Company at the principal executive offices of the Company, and must include information regarding the candidate and the stockholder making the recommendation.

Other Committees

        The Board has also established a Steering Committee and Cybersecurity Committee.

        Our Steering Committee assists the Board in establishing the Company's long-term strategy and also advises on other strategic matters.

        Our Cybersecurity Committee assists the Board in setting accountability of management regarding cybersecurity preparedness, assessing the adequacy of resources and funding to sustain a successful cybersecurity program, providing guidance regarding management's recommendations related to cybersecurity initiatives and providing guidance regarding management's framework for responding to cybersecurity incidents.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

        Each of Charles Boesenberg, Chuck Davis and Mike Finley served on the Compensation Committee of the Board of Directors during 2016 and David Cutrer was appointed to the Compensation Committee in June 2016. None of the members of the Compensation Committee was at any time during the 2016 fiscal year (or at any other time) an officer or employee of the Company. None of our executive officers serves as a member of the board of directors or compensation committee of any entity that has one or more executive officers serving as a member of our Board of Directors or Compensation Committee.

BOARD LEADERSHIP STRUCTURE

        Our Board of Directors has combined the roles of Chairman and Chief Executive Officer, who is David Hagan, our Chief Executive Officer, as Chairman of the Board. Our Board has determined that we would be best served by having a Chairman with deep operational and strategic knowledge of our business. Our Board has also appointed Charles Boesenberg as our Lead Independent Director. Our Board has determined that we would be best served by also having a lead independent director to be responsible for calling special meetings of the independent directors and chairing all meetings of the independent directors.

RISK OVERSIGHT MANAGEMENT

        Our Board provides risk oversight for our entire company by receiving management presentations, including risk assessments, from all functional areas of our company, and discussing these assessments with management. The Board's overall risk oversight is supplemented by the various committees. The Audit Committee discusses with management and our independent auditors our risk management guidelines and policies, our major financial risk exposures and the steps taken to monitor and control such exposures.

        Our Compensation Committee oversees risks related to our compensation programs and discusses with management its annual assessment of our employee compensation policies and programs. Based upon this review, our Compensation Committee believes that any risks arising from such policies and practices are not reasonably likely to have a material adverse effect on the Company in the future. Specifically, we believe that the elements of our compensation program do not encourage unnecessary or excessive risk-taking. Base salaries are fixed in amount and thus do not encourage risk-taking. A significant proportion of the compensation provided to our executives, and a material amount of the compensation provided to other employees, is in the form of long-term equity awards that are important to help further align employee interests with those of our stockholders. We do not believe that these awards encourage unnecessary or excessive risk-taking because the ultimate value of the awards is tied to our stock price, and because awards are staggered and subject to long-term vesting schedules to help ensure that employees have significant value tied to long-term stock price performance.

COMMUNICATIONS WITH OUR BOARD OF DIRECTORS

        Our Board desires that the views of the Company's stockholders will be heard by our Board, its committees or individual directors, as applicable, and that appropriate responses will be provided to stockholders on a timely basis. Stockholders wishing to formally communicate with our Board of Directors, any Board committee, the independent directors as a group or any individual director may send communications directly to the Company at Boingo Wireless, Inc., 10960 Wilshire Blvd., 23rd Floor, Los Angeles, California 90024, Attention: Corporate Secretary. All clearly marked written communications, other than unsolicited advertising or promotional materials, are logged and copied, and forwarded to the director(s) to whom the communication was addressed. Please note that the foregoing communication procedure does not apply to (i) stockholder proposals pursuant to Exchange Act Rule 14a-8 and communications made in connection with such proposals, (ii) stockholder proposals and director nominations pursuant to our bylaws or (iii) service of process or any other notice in a legal proceeding.

MEETINGS OF THE BOARD OF DIRECTORS

        The Board of Directors met seven times during 2016. Each Board member attended 75% or more of the aggregate of the meetings of the Board and of the committees on which he or she served, held during the period for which such member was a director or committee member. Members of the Board

and its committees also consulted informally with management from time to time and acted at various times by written consent without a meeting during 2016. We do not have a formal policy regarding attendance by members of the Board of Directors at our annual meetings of stockholders, and all of our directors attended our 2016 Annual Meeting of Stockholders.

CODE OF BUSINESS CONDUCT AND ETHICS

        The Company has adopted the Boingo Wireless, Inc. Code of Business Conduct and Ethics that applies to all directors, officers and employees. A copy is available on the corporate governance section of our website at www.boingo.com. If the Company makes any substantive amendments to the Code of Business Conduct and Ethics or grants any waiver from a provision of the Code to any executive officer or director, the Company will promptly disclose the nature of the amendment or waiver in its public filings, as required by law or securities market regulations.

Equity-Based Compensation

        Our equity compensation program for non-employee directors provides for the grant of restricted stock units ("RSUs") and is comprised of both an initial equity award upon joining our Board of Directors and annual equity awards in connection with each annual meeting of our stockholders.

•

Initial Equity Award—Each new non-employee director joining our Board will receive a one-time RSU award covering a number of shares equal to the quotient obtained by dividing $200,000 by the average of the closing sales price of our common stock for the five consecutive trading days prior to the date of grant (rounded down to the next whole number of shares of our common stock). The RSUs will vest 33¹/3% per year over a three-year period of continuous service. In addition, such RSUs will vest in full upon the earlier of (a) the occurrence of a change in control on or before the date the director's service with us terminates, or (b) the day immediately prior to our first regular annual meeting of stockholders that occurs in the third year following the date of grant.



•

If the non-employee director is elected to our Board of Directors, the grant will be made on the date the non-employee director becomes elected to the Board of Directors.



•

If the non-employee director is instead appointed to our Board of Directors, the grant will be made on the first Tuesday of the month occurring after the date the non-employee director was appointed to the Board of Directors; provided, however, that if such date occurs during a blackout period as determined under the Company's Insider Trading Policy, the effective date of the grant will be the next occurring Tuesday that is not in a blackout period.



•

Annual Equity Award—Following the conclusion of each regular annual meeting of stockholders, each continuing non-employee director will receive a RSU award covering a number of shares equal to the quotient obtained by dividing $120,000 by the average of the closing sales price of our common stock for the five consecutive trading days prior to the date of grant. In addition to the foregoing, the lead independent director of our Board of Directors will receive a RSU award covering a number of shares equal to the quotient obtained by dividing $66,000 by the average of the closing sales price of our common stock for the five consecutive trading days prior to the date of grant. Such RSUs will vest in full upon the earliest of (a) the first anniversary of the

date of grant, (b) the occurrence of a change in control on or before the date the director's service with us terminates, or (c) the day immediately prior to our first regular annual meeting of stockholders that occurs in the year following the date of grant.

        The following table sets forth information about the compensation of each person who served as a director during the 2016 fiscal year, other than a director who also served as a named executive officer.

Non-Employee Director Stock Ownership Guidelines

        In January 2016, our Compensation Committee adopted stock ownership guidelines for our non-employee directors and our named executive officers. The ownership guidelines provide for a three year transition period from their adoption, and will require that our non-employee directors hold shares and share equivalents equal in value to three times their annual retainer. For purposes of the stock ownership guidelines, vested RSUs and vested and in-the-money options will be counted toward the applicable requirement.

Based on a combination of business strategy considerations, stockholder input and compensation design review, our Compensation Committee repositioned the equity compensation for our named executive officers to establish a strong focus on growing our business over the next three years.

        In connection with this repositioning, our Chief Executive Officer and Chief Financial Officer each agreed to delay the vesting of their restricted stock unit awards ("RSUs") granted in fiscal years 2014 and 2015. This change, which imposes increased risk of forfeiture on the awards, essentially converted the portion of the RSUs that remained unvested into awards that cliff vest at the end of their respective three-year vesting terms. In addition, and in consideration of this change to their outstanding RSUs, our Compensation Committee determined in early 2016 to grant each of Mr. Hagan and Mr. Hovenier RSUs that encompass the number of shares each officer might otherwise have been granted during the 2016-2018 period, with all of these award shares eligible to "cliff" vest at the end of their three-year terms in 2019 (subject to satisfaction of the applicable service-based and

performance-based vesting conditions). We refer to the 2016 RSUs for Messrs. Hagan and Hovenier as the "3-Year Awards".

        In addition, our Compensation Committee enhanced the performance-basis of our long-term incentive program, including with respect to the 3-Year Awards, in several respects:

•

It increased the portion of the awards granted to each of our named executive officers that are performance-based from one-third to 50% of the aggregate grant value so that the 2016 equity awards for all of our named executive officers are 50% time-based RSUs and 50% (at-target) performance-based RSUs. This change had the corresponding effect of reducing the portion of RSUs that vest based on continued service alone from two-thirds to 50%;



•

The 2016 performance-based RSUs granted to our named executive officers included an Adjusted EBITDA margin objective, in addition to the revenue objective that had been the sole performance objective used in 2015; and



•

It lengthened the applicable performance period from one to two fiscal years.

        Additional highlights for our fiscal 2016 executive compensation programs are:

•

The base salaries of our named executive officers were increased between 3% to 8% to account for cost of living increases, achieve certain pay equity objectives and more closely align certain executives with the 50^th percentile for total cash compensation of our peer group;



•

Our Compensation Committee determined that revenue and Adjusted EBITDA objectives remained appropriate performance goals applicable to our cash-based annual management incentive compensation plan. The revenue and Adjusted EBITDA objectives were originally selected based on the desire to strongly encourage responsible revenue growth with profitability during the year while continuing to focus on our long-term strategy of monetizing our high-density wireless networks, including DAS and Wi-Fi networks; and



•

Cash bonuses were paid under the annual management incentive compensation plan at 95% of target based upon the pre-established performance goals for 2016 (revenue and Adjusted EBITDA), which our Compensation Committee determined to be an appropriate level in light of the Company achieving the financial objectives and growing the Company's business.

        See below in "Elements of Compensation" for more detailed discussion of these components of our fiscal 2016 executive compensation program.

Post-2016 Compensation Highlights

        In our continued effort to respond to input we receive from our stockholders, in early 2017 our Compensation Committee determined that a new performance objective consisting of free cash flow would be added to our cash-based annual management incentive compensation plan for fiscal 2017, and that the weightings of the three performance objectives (revenue, Adjusted EBITDA and free cash flow) would also be adjusted. For fiscal 2017, cash bonuses under the management incentive compensation plan will be paid based on achievement of the three objectives, with the following weightings: 45% for both revenue and Adjusted EBITDA and 10% for free cash flow.

Corporate Governance Considerations

        In January 2016, the Company adopted stock ownership guidelines to reinforce its belief that executives who believe in the future of the Company should have meaningful equity holdings in the Company. The ownership guidelines provide for a three-year transition period from their adoption, and will require that our directors hold shares and share equivalents equal in value to three times their annual retainer and that each of our executive officers hold shares and share equivalents equal in value

to a multiple of base salary, specifically, six times base salary for our Chief Executive Officer and one times base salary for each of our other executive officers. For purposes of the stock ownership guidelines, vested RSUs and vested and in-the-money options will be counted toward the applicable requirement.

Risk Considerations

        As discussed in "Risk Oversight Management" above, the Compensation Committee reviews our compensation programs annually and concluded in 2016 that such programs do not create risks that could be reasonably likely to have a material adverse effect on us.

General Overview and Objectives of our Executive Compensation Programs

        Historically, our compensation programs have aimed to conserve cash while attracting and retaining executive officers who are highly motivated to grow our business in the long term. As with other emerging companies in the wireless industry and the technology sector generally, we emphasize equity compensation, through a mix of time-based and performance-based RSUs, to align the interests of management and stockholders, which we believe motivates the management team to grow the business in the long term. The Compensation Committee believes that the total cash compensation of our named executive officers (including their base salary plus annual incentive bonus) should target the 50^th percentile of our selected peer group and that total direct compensation (total cash compensation plus equity awards) should target the 60^th percentile of our selected peer group.

        We recognize that our success depends to a great degree on the integrity, knowledge, imagination, skill, diversity and teamwork of our employees. To this end, we designed, and intend to modify as necessary, our compensation and benefits program and philosophy in order to attract, retain and motivate talented, highly qualified and committed executive officers who share our business goals and corporate values. In doing so, we strive to reward achievement of clear, easily measured performance goals that keep our executive officers focused on accomplishing our long-term business objectives, while offering sufficient fixed compensation to remain competitive within our industry and geography. We expect to continue relying on this approach in the future.

        The principal objectives of our executive compensation programs are:

•

attracting, retaining and motivating talented and experienced executives;



•

rewarding executives whose knowledge, skills and performance are critical to and demonstrably contribute to our success and strategic goals; and



•

incentivizing our executives to manage our business as a team.

Role of the Compensation Committee, Board of Directors and Management in Setting Executive Compensation

        In general, our Compensation Committee makes compensation decisions regarding our named executive officers. During 2016, Messrs. Boesenberg, Cutrer, Davis, and Finley served as the committee members. The Compensation Committee has overall responsibility for overseeing and, together with input from the full Board of Directors as the committee deems appropriate, approving the compensation of our Chief Executive Officer and other executive officers.

        We anticipate that our Chief Executive Officer will continue to make recommendations to our Compensation Committee regarding compensation for other executive officers. However, while our Compensation Committee will consider our Chief Executive Officer's recommendations, it need not adopt these recommendations and may adjust them as it deems appropriate together with input from the full Board of Directors. The committee has authority to approve all compensation decisions regarding our executive officers, although our Board of Directors also retains concurrent authority. The

27

Table of Contents

committee may from time to time refer matters to the entire Board of Directors in order to obtain input from other directors prior to making a decision and, if appropriate, may submit matters for approval by the full Board of Directors. Other executive officers, including our Chief Financial Officer and our Senior Vice President Human Resources, participate in Compensation Committee meetings from time to time, primarily to present information to the Committee.

Independent Compensation Consultant and Peer Group

        Our Compensation Committee has the authority to engage the services of outside consultants and advisors to assist it in making decisions regarding our executive compensation programs. In early 2014, the Compensation Committee retained The Croner Company to advise the Committee regarding the compensation of our executive officers and non-employee directors, replacing our former compensation consultant, Compensia. The Compensation Committee believed that The Croner Company's deep expertise in the technology industry would provide the Committee with relevant and targeted advice.

        To assist the Compensation Committee in evaluating the different components of compensation to be paid to our named executive officers, the Compensation Committee relies on compensation data from a group of peer companies developed with the assistance of The Croner Company. The direction of the Compensation Committee in setting a peer group for 2016 was to include companies within 40% to 250% of the Company's revenue and with a market cap between $50 million and $4 billion, with similar or relevant business models and technology and communications companies located in our geographic area. For 2016 compensation decisions, the Compensation Committee relied on the following peer group of companies:

        The compensation data from the peer group of companies developed with The Croner Company is used in evaluating our executive compensation program. Our Compensation Committee previously made the decision that the total cash compensation of our named executive officers (including their base salary plus annual incentive target bonus) should generally target the 50^th percentile of our selected peer group and that total direct compensation (total cash compensation plus the grant date value of annual equity awards) should generally target the 60^th percentile of our selected peer group compensation data. Our Compensation Committee generally remained focused for 2016 compensation decisions on these same targets, although it recognized that its decision to grant the 3-Year Awards to our Chief Executive Officer and Chief Financial Officer will skew this result for each officer for the period between 2016 through 2018.

Elements of Compensation

        Our executive compensation program currently includes the following components:

•

annual base salary;



•

annual cash incentive bonus;

28

---

Table of Contents

•

equity-based awards, including both time-based and performance-based awards; and



•

certain benefits upon involuntary termination of employment under specified circumstances.

        The weight of each of these components has not to date been determined by any particular formula, although our overall mix of total compensation has historically emphasized and continues to emphasize equity-based awards for their long-term incentive and retention value. The specific mix of components has been and will continue to be within the discretion and business judgment of our Board of Directors and the Compensation Committee, which have placed greater emphasis on the dynamics within and strategic direction of the Company and to considerations specific to the individual holding a particular executive position than on general market data.

        The following table provides a breakdown for 2016 compensation for our named executive officers between fixed and variable compensation. Fixed compensation is comprised of annual base salary and time-based equity awards, as it does not vary based on the Company's performance, whereas variable compensation is comprised of annual cash incentive bonuses and performance-based awards, as the value of both components is inherently tied to the Company's performance.

Base Salary

        We provide a base salary to our named executive officers to compensate them for services rendered on a day-to-day basis during the year and to provide sufficient fixed cash compensation to allow them to focus on their ongoing responsibilities. The base salaries of all executive officers are reviewed annually and adjusted when necessary to reflect individual roles and performance as well as market conditions. In connection with the Compensation Committee's annual review process in January 2016, the base salaries of our named executive officers were each increased for 2016, to account for both an increase in the cost of living, to address certain internal pay equity issues, and to more closely align the executives with the 50^th percentile for total cash compensation of our peer group (bringing our named executive officers from 95% of the 50^th percentile to 98%). The named executive officers received a base salary increase ranging from 3% to 8%, with Dr. Peterson receiving the largest increase at 8% to position him at 9% of the 50^th percentile of our peer group. The actual base salary increases that our named executive officers received are as follows: Mr. Hagan's base salary was increased from $500,000 to $515,000; Mr. Hovenier's base salary was increased from $324,000 to approximately $337,000; Ms. Callahan's base salary was increased from $276,000 to approximately $284,000; Dr. Peterson's base salary was increased from $275,000 to $297,000; and Mr. Tracey's base salary was increased from $268,000 to approximately $276,000.

Annual Cash Incentive Bonuses

        We use annual cash incentive bonuses to reward our named executive officers for the achievement of company performance goals. Each year, we adopt new corporate financial objectives under our management incentive compensation plan to motivate and reward our senior executives, including our

29

Table of Contents

named executive officers, to attain specific short-term performance objectives that, in turn, further our long-term business objectives. These objectives are based upon corporate targets, rather than individual objectives. In setting target payout levels under our management incentive compensation plan, our Compensation Committee considered historical payouts, the total cost to the company should performance objectives be achieved and our retention needs. The Compensation Committee retains discretion to reduce or eliminate payment under our management incentive compensation plan.

        For 2016, the performance goals under our management incentive compensation plan included revenue and Adjusted EBITDA, the same two corporate financial objectives as in the prior year. For each goal in 2016, we established a threshold and a maximum achievement level, as well as a weighting as a proportion of the total bonus objective. The revenue and Adjusted EBITDA objectives were originally selected based on the desire to strongly encourage responsible revenue growth with profitability during the year as well as continued focus on our long-term strategy of monetizing our high-density wireless networks, including DAS and Wi-Fi networks. For 2016, the Compensation Committee determined it would be appropriate to weight revenue at 80% and Adjusted EBITDA at 20%, which was the same as the prior year. In connection with our continued efforts to respond to input we receive from our stockholders, for our 2017 management incentive compensation plan our Compensation Committee determined that a third performance objective consisting of free cash flow would be added to the two objectives utilized in 2016. In addition, the Compensation Committee reallocated the weightings of the performance objectives so that 2017 cash bonuses will be paid based on the following weightings: 45% for both revenue and Adjusted EBITDA and 10% for free cash flow.

        For the 2016 cash bonuses, each financial target, achievement of the target equates to 100% of the bonus payout. With respect to the revenue objective, underachievement at the floor of 90% of the financial target results in a bonus payout of 50% for the objective and overachievement at 110% results in a bonus payout of 150% for the objective. For the Adjusted EBITDA objective, underachievement at the floor of 70% of the financial target results in 50% of the bonus payout for the objective and overachievement at 120% results in a bonus payout of 150% for the objective. Below the floor levels of each of the financial targets, there is no bonus payout. In the event of any under or overachievement, straight line interpolation is applied from target levels.

        Target bonuses for our named executive officers under the 2016 plan were as follows:

30

Table of Contents

        The relative weighting of each financial objective, together with 2016 target levels, actual achievement, and the percentage of target achieved, is as follows:

        In February 2017, our Compensation Committee determined the achievement of the financial objectives applicable under the management incentive compensation plan for 2016 at a 95% level, resulting in bonus payouts as follows: Mr. Hagan—$488,130; Mr. Hovenier—$239,867; Ms. Callahan—$147,982; Dr. Peterson—$154,827; and Mr. Tracey—$143,794. The portion of these amounts attributable to revenue were paid on a quarterly basis; any remaining unpaid amounts, including the portion attributable to Adjusted EBITDA, were paid following the end of the calendar year.

Equity-Based Awards

        We believe that equity-based awards encourage our named executive officers to focus on the long-term performance of our business. Our Compensation Committee grants equity awards to executives and other employees in order to enable them to participate in the long-term appreciation of our stock price. Additionally, we believe our equity awards provide an important retention tool for our named executive officers, as they are subject to multi-year vesting.

        While we have, in the past, granted equity-based awards in the form of stock options, our current grant practices utilize time-based and performance-based RSUs. We believe that RSUs are the appropriate form of equity award for our Company in the current competitive conditions in the wireless industry for which we compete for executive talent, and allow us to both retain current employees and compete in the market when hiring new employees and provide employees a more tangible benefit and while limiting dilution to the Company.

        In late 2015, our Board and Compensation Committee began formulating a strategic plan that would focus the Company on our long-term growth strategy, with the particular goal of driving toward, and focusing management's attention on achieving, the desired level of Company growth and profitability over the following three years. At the same time, as a result of contemporaneous outreach and engagement with our stockholders, we received input from certain of our stockholders about sales of our common stock in the market by our Chief Executive Officer and Chief Financial Officer to cover taxes arising upon vesting of equity awards. This combination of business strategy considerations, stockholder input and compensation design review resulted in our Compensation Committee making several significant changes in early 2016 to the long-term equity award components of our executive

31

Table of Contents

compensation programs, in particular with respect to equity awards for our Chief Executive Officer and our Chief Financial Officer.

        First, in response to the stockholder input regarding market sales by our senior management, it approved the restructuring of outstanding equity awards granted to our Chief Executive Officer and Chief Financial Officer in 2014 and 2015 to delay interim vesting dates for such awards until the final vesting date applicable to each award. This eliminated their need to sell shares to cover tax withholding obligations arising in connection with the interim vesting dates and decreased the frequency with which our Chief Executive Officer and Chief Financial Officer would need to sell shares of our common stock in the market. In connection with this equity award restructuring and to support the tax position on which the restructuring was based, we entered into an agreement with each officer whereby he accepted the increased risk of forfeiture resulting from the delayed vesting in consideration for receiving 2016 long-term incentive awards that encompass the number of shares that might otherwise have been granted in annual installments over 2016, 2017 and 2018. We refer to each of these awards as a 3-Year Award.

        Specifically, Messrs. Hagan and Hovenier each agreed, effective as of February 1, 2016, to extend the vesting that applied to his previously-granted time-based and performance-based RSUs such that portions of RSUs granted to each officer in 2014 and scheduled to vest in quarterly installments between June 2016 and March 2017 would instead "cliff vest" on March 1, 2017, and the portions of RSUs granted in 2015 and scheduled to vest in quarterly installments between June 2016 and March 2018 would instead "cliff vest" on March 1, 2018.

        Second, our Compensation Committee in January 2016 approved for each of Messrs. Hagan and Hovenier new 3-Year Awards in the form of RSUs, each of which are eligible to vest on February 1, 2019, subject to satisfaction of specified time-based and performance-based conditions. These 3-Year Awards are intended to be the only long-term equity awards each executive officer will receive until 2019. The 3-Year Awards were equally portioned between time-based RSUs (50% of the grant value) and performance-based RSUs (50% of the grant value based upon at-target performance), increasing the portion of our long-term incentive awards that are performance-based from one-third to 50%. Correspondingly, the number of RSUs that vest based solely on continued service decreased from two-thirds of the grant value to 50%.

        The performance-based RSUs are subject to two equally-weighted performance objectives: 50% of the at-target value is based upon achieving specified average revenue growth over a two-year period ending on December 31, 2017, as compared with revenue in the year ending on December 31, 2015, and 50% is based upon Adjusted EBITDA margin targets, measured at the end of 2017. This structure has the effect of lengthening the performance period that applies to our long-term incentive awards from one year to two years and also adding an additional performance objective. The performance objectives are subject to under- or over- achievement on a sliding scale, with 50% of the target number of shares vesting on achievement of the minimum performance objectives, and up to a maximum of 150% of the target number of shares vesting upon maximum achievement, with straight-line interpolation applied between performance increments. Following achievement of the revenue growth and Adjusted EBITDA margin performance objectives to establish the number of RSUs eligible to vest, Messrs. Hagan and Hovenier must remain in service through February 1, 2019 in order to vest in such number of RSUs.

        Mr. Hagen's 3-Year Awards, which provide for the issuance of up to 1,462,987 shares of common stock assuming satisfaction of the continued service requirements and maximum achievement of the performance-based targets, was approved in two tranches as a result of the annual limit of 1,000,000 shares per year that can be granted to an individual employee under the Company's 2011 Equity Incentive Plan. Our Compensation Committee approved the first tranche of up to 1,000,000 shares in early 2016, and our Board approved the second tranche of up to 462,987 shares subject to Mr. Hagan's

32

Table of Contents

performance-based 3-Year Award in early 2017. Because the Company committed in 2016 to grant Mr. Hagan the 3-Year Awards, including as part of the consideration promised for his agreement to extend the vesting of his 2014 and 2015 equity awards, the full value of his 3-Year Awards are treated as 2016 equity grants for financial statement purposes, although a portion of the shares subject to his performance-based 3-Year Award required approval in 2017.

        Finally, our Compensation Committee continued in 2016 to push our long-term incentive program for all our executive officers toward a longer-term and stronger growth model by making several design changes to the RSUs granted in 2016 compared to those granted in 2015. This design approach for the entire senior management team is similar to the 2016 RSUs granted to our Chief Executive Officer and Chief Financial Officer, but without imposing the three-year cliff vesting on the awards granted to other executive officers. First, as with the 3-Year Awards, the 2016 RSUs granted to our other executive officers increased the portion of the awards that are performance-based from one-third of the aggregate grant value to 50% of the aggregate grant value so that the 2016 awards granted to all of our named executive officers are 50% time-based RSUs and 50% (at-target) performance-based RSUs. Second, as with the 2016 performance-based RSUs granted to our Chief Executive Officer and Chief Financial Officer, the 2016 performance-based RSUs granted to our other named executive officers added an Adjusted EBITDA margin objective and lengthened the applicable performance period from one to two fiscal years. The RSU grants to Ms. Callahan, Dr. Peterson and Mr. Tracey, however, are not subject to vesting only at the end of 2019. Instead, the 2016 time-based RSUs began vesting in 12 equal quarterly installments on May 1, 2016, subject to each executive officer's continued service through each vesting date, and the 2016 performance-based RSUs will vest as to 66²/3% of the RSUs that become eligible to vest based on performance on the date in 2018 on which our Compensation Committee determines the achievement, an additional 8¹/3% of such RSUS will vest on May 1, 2018, and an additional 8¹/3% of such RSUs will vest upon the executive officer's completion of an additional quarter of continuous service thereafter.

        The actual number of 2016 time-based RSUs and 2016 performance-based RSUs (at target) granted (or in the case of Mr. Hagan, committed to) to each of our named executive officers is as follows:

        Our Compensation Committee recognized that its determination in 2016 to grant the 3-Year Awards to our Chief Executive Officer and our Chief Financial Officer would result in the entire value of the awards being reflected as compensation in our Summary Compensation Table for fiscal year 2016 under applicable disclosure rules. Correspondingly, even though these awards also cover fiscal years 2017 and 2018, no value related to these awards will be reflected in our Summary Compensation Table for those later years. With respect to the decision-making process of our Compensation Committee, it is important to understand that the committee views the value of the 3-Year Awards as being allocated in equal amounts to each of the three fiscal years covered by the awards. That approach informed the Compensation Committee's analysis when it considered and determined during 2016 the compensation decisions for Messrs. Hagan and Hovenier, including as it reviewed the applicable market data. It informed in the same manner the Compensation Committee's analysis during 2017 (with no additional equity awards being granted to either executive officer), and we expect that it will have the same

Table of Contents

impact on the Compensation Committee's decision-making process during 2018. Footnote 1 to the Summary Compensation Table contains an alternative "summary compensation table" including only the portion of the 3-Year Awards that relate to 2016 under the Compensation Committee's approach. When compared to the 2016 peer group market data, the compensation reflected in the alternative summary compensation table results in Mr. Hagan's total direct compensation being slightly above the 60^th percentile of the 2016 peer group market data and Mr. Hovenier's total direct compensation being above the 60^th percentile of our 2016 peer group market data. The extent to which Mr. Hovenier's total direct compensation exceeds the targeted 60^th percentile point results from an adjustment to his compensation undertaken in 2015, largely driven by internal pay equity consideration.

        We do not have, nor do we plan to establish, any program, plan or practice to time equity award grants in coordination with releasing material non-public information, nor do we have any established grant schedule.

Severance and Change of Control Benefits

        Our Board of Directors believes that it is necessary to offer senior members of our executive team severance benefits to ensure that they remain focused on executing our strategic plans, including in the event of a proposed or actual acquisition. We have entered into employment agreements with our named executive officers to provide them with additional severance benefits upon an involuntary termination of employment under specified circumstances prior to and following a change of control. The terms of these agreements are described below in "Severance or Employment Agreements."

        Additionally, the 2016 RSUs granted to Messrs. Hagan, Hovenier and Tracey and Ms. Callahan provide that if the officer were to be involuntarily terminated outside the change of control context, then they would be treated as vested in a number of shares underlying the award equal to the sum of the number of shares applying a monthly pro-rata vesting over the 3-year overall vesting schedule (with the performance-based RSUs determined at 100% of target if before the date performance has been determined to be achieved, and at the actual level of achievement if after such date), plus in Mr. Hagan's case an additional 24 months of vesting, in Mr. Hovenier's case an additional 12 months of vesting or in Ms. Callahan's, Dr. Peterson's or Mr. Tracey's case, an additional 9 months of vesting. Upon an involuntary termination in connection with a change of control, each officer would be entitled to full vesting of these awards, with achievement of the performance-based award deemed to be at-target if the transaction occurred prior to the end of the two-year performance period and at the actual achievement level if the transaction occurred during 2018.

Perquisites

        We do not provide any significant perquisites or other personal benefits to our named executive officers.

Benefits

        We provide the following benefits, which we believe are typical of the companies with which we compete for employees, to our named executive officers on the same basis provided to all of our employees:

•

health, dental and vision insurance;



•

life insurance and accidental death and dismemberment insurance;



•

a 401(k) plan;



•

an employee assistance plan;



•

short and long-term disability insurance;

•

a medical and dependent care flexible spending account; and



•

a health savings account.

Tax Considerations

        We do not provide any tax gross-ups to our executive officers or directors.

        Section 162(m) of the Code limits deductibility of certain compensation to $1.0 million per year for the Chief Executive Officer and the three other executive officers (other than the Chief Financial Officer) who are highest paid and employed at year-end. If certain conditions are met, performance-based compensation may be excluded from this limitation. The stock options we have granted to named executive officers to date are designed to qualify as performance-based compensation for purposes of Section 162(m). We expect that a portion of our compensation amounts related to performance-based RSUs will not be fully deductible as a result of the Section 162(m) limitations.

        While our Compensation Committee has not adopted a formal policy regarding tax deductibility of compensation paid to our named executive officers, our Compensation Committee may exercise discretion to pay nondeductible compensation if following the requirements of Section 162(m) is not feasible in light of all strategic goals, contractual commitments and such other factors as our Compensation Committee considers in its judgment appropriate.

SECURITIES AUTHORIZED FOR ISSUANCE UNDER EQUITY COMPENSATION PLANS

        We have two equity compensation plans under which shares of Common Stock are authorized for issuance to eligible employees, directors, and consultants: (i) the Amended and Restated 2001 Stock Incentive Plan, or 2001 Plan; and (ii) the 2011 Equity Incentive Plan, or Incentive Plan. The following table provides certain information with respect to each of our equity compensation plans in effect as of December 31, 2016:

        In March 2011, our Board of Directors and stockholders approved the Incentive Plan. The Incentive Plan became effective on May 3, 2011 upon the completion of our initial public offering. The Incentive Plan provides for the grant of incentive and non-statutory stock options, stock appreciation rights, restricted shares of our common stock, restricted stock units, and performance cash awards. The number of shares of common stock reserved for issuance under the Incentive Plan automatically increases on January 1 of each calendar year through 2018 by an amount equal to the least of (a) 4.5% of the total number of shares of common stock then outstanding, (b) 3,000,000 shares of common stock or (c) a lower number determined by our Board of Directors. As of December 31, 2016, options to purchase 1,994,270 shares of common stock and RSUs covering 4,358,472 shares of common stock were outstanding under the Incentive Plan.

        Our Board of Directors and stockholders approved the 2001 Plan. The 2001 Plan was terminated following the completion of our initial public offering, and no further awards will be made under that plan. Options outstanding under the 2001 Plan will continue to be governed by their existing terms. As of December 31, 2016, options to purchase 1,089,702 shares of common stock were outstanding under the 2001 Plan.

REPORT OF THE AUDIT COMMITTEE OF THE BOARD OF DIRECTORS(1)

        The Audit Committee of the Board of Directors consists of the four non-employee directors named below and operates under a written charter adopted by the Board. The Board annually reviews the Nasdaq listing standards' definition of independence for Audit Committee members and has determined that each member of the Audit Committee meets that standard. The Board of Directors has also determined that Charles Boesenberg, Maury Austin, Terrell Jones and Lance Rosenzweig each is an audit committee financial expert as described in applicable rules and regulations of the Securities and Exchange Commission.

        The principal purpose of the Audit Committee is to assist the Board of Directors in its general oversight of our accounting and financial reporting processes and audits of our financial statements. The Audit Committee is responsible for selecting and engaging our independent auditor and approving the audit and non-audit services to be provided by the independent auditor. The Audit Committee's function is more fully described in its Charter, which the Board adopted and which the Audit Committee reviews on an annual basis.

        Our management is responsible for preparing our financial statements and our financial reporting process. PricewaterhouseCoopers LLP, our independent registered public accounting firm, is responsible for performing an independent audit of our consolidated financial statements and expressing an opinion on the conformity of those financial statements with U.S. generally accepted accounting principles as well as performing an audit of the effectiveness of our internal control over financial reporting as of the end of the fiscal year.

        The Audit Committee has reviewed and discussed with our management the audited financial statements of the Company included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2016 ("10-K").

        The Audit Committee has also reviewed and discussed with PricewaterhouseCoopers LLP the audited financial statements in the 10-K. In addition, the Audit Committee discussed with PricewaterhouseCoopers LLP those matters required to be discussed by the auditors with the Audit Committee under the rules adopted by the Public Company Accounting Oversight Board (the "PCAOB"), including General Auditing Standards 1301, Communications with Audit Committees. Additionally, PricewaterhouseCoopers LLP provided to the Audit Committee the written disclosures and the letter required by the applicable requirements of the PCAOB regarding the independent accountant's communications with the Audit Committee concerning independence. The Audit Committee also discussed with PricewaterhouseCoopers LLP its independence from the Company and satisfied itself as to the independence of PricewaterhouseCoopers LLP.

        Based upon the review and discussions described above, the Audit Committee recommended to the Board of Directors that the audited financial statements be included in the Company's 10-K for filing with the Securities and Exchange Commission.

PROPOSAL 1
ELECTION OF DIRECTORS

        Our Board of Directors currently consists of nine directors divided into three classes, with the terms of office of each class ending in successive years. The term of the directors currently serving in Class III expire on the date of the Annual Meeting.

        The directors in Class I and Class II will continue in office until their terms expire at the 2018 and 2019 annual meeting of stockholders, respectively. The directors elected in Class III at the Annual Meeting will hold office until the 2020 annual meeting of stockholders or until their successors are duly elected and qualified. The nominees for director in Class III and the other directors who will continue in office for terms extending beyond the Annual Meeting, their ages as of April 1, 2017, their positions and offices held with the Company are set forth below. Other biographical information for the nominees for director in Class III and the other directors who will continue in office for terms extending beyond the Annual Meeting is set forth in this proxy statement under the heading "Directors, Executive Officers and Corporate Governance—Directors and Executive Officers."

        Directors are elected by a majority of the votes cast in an uncontested election of directors. Therefore, in an uncontested election of directors (i.e., an election where the only nominees are those recommended by our Board), each member of our Board will be elected only if the votes cast for the nominee exceed the votes cast against the nominee. Shares represented by executed proxies will be voted, if authority to do so is not withheld, for the election of the three nominees named below. However, if you are the beneficial owner of the shares, which means that your shares are held by a brokerage firm, bank, dealer, or other similar organization as your nominee, your shares will not be voted for the election of directors unless you have provided voting instructions to your nominee. If any nominee becomes unavailable for election as a result of an unexpected occurrence, your shares will be voted for the election of a substitute nominee proposed by our current Board of Directors, if any. Each person nominated for election has agreed to serve if elected. We have no reason to believe that any nominee will be unable to serve.

        We have also implemented a majority voting policy for director resignations, applicable if an incumbent director nominee receives less than a majority of votes cast in an uncontested election. Each director nominated for reelection must tender his or her written irrevocable, conditional resignation to the Chairman of the Board that will be effective only upon both (i) the failure to receive the required vote at the Annual Meeting and (ii) Board acceptance of such resignation. If a director nominee fails to receive the required vote for reelection, our Nominating and Corporate Governance Committee (other than such director) will act on an expedited basis to determine whether to accept the director's irrevocable, conditional resignation, and it will submit such recommendation for prompt consideration by the Board. The Nominating and Corporate Governance Committee and members of the Board (other than such director) may consider any factors they deem relevant in deciding whether to accept a director's resignation. This policy does not apply in circumstances involving contested director elections.

        The nominees recommended by your Board have consented to serving as nominees for election to the Board, to being named in this proxy statement and to serving as members of the Board if elected by Boingo's stockholders. As of the date of this proxy statement, we have no reason to believe that any nominee will be unable or unwilling to serve if elected as a director. However, if for any reason a nominee becomes unable to serve or for good cause will not serve if elected, the Board upon the recommendation of its Nominating and Corporate Governance Committee may designate substitute nominees, in which event the shares represented by proxies returned to us will be voted for such substitute nominees. If any substitute nominees are so designated, we will file an amended proxy statement that, as applicable, identifies the substitute nominees, discloses that such nominees have consented to being named in the amended proxy statement and to serve as directors if elected, and

includes certain biographical and other information about such nominees required by the applicable rules promulgated by the SEC.

NOMINEES FOR CLASS III CONTINUING IN OFFICE UNTIL THE 2017 ANNUAL MEETING OF STOCKHOLDERS

        Messrs. Austin's, Davis' and Finley's biographies are set forth in this proxy statement under the heading "Directors, Executive Officers and Corporate Governance—Directors and Executive Officers."

        We have determined that each of these director nominees possesses the requisite communication skills, personal integrity, business judgment, ability to make independent analytical inquiries, and willingness to devote adequate time and effort necessary to serve as an effective member of the Board. Other specific experiences, qualifications, attributes or skills of nominees that contributed to our conclusion that the nominees should serve as directors are noted in their biographies.

PROPOSAL 2
RATIFICATION OF APPOINTMENT OF PRICEWATERHOUSECOOPERS LLP AS OUR
INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE FISCAL YEAR ENDING DECEMBER 31, 2017

        The Audit Committee of the Board of Directors has selected PricewaterhouseCoopers LLP, independent registered public accounting firm, as our independent auditors for the fiscal year ending December 31, 2017 and has further directed that management submit the selection of independent auditors for ratification by the stockholders at the Annual Meeting.

        Neither our bylaws nor other governing documents or law require stockholder ratification of the selection of PricewaterhouseCoopers LLP as our independent registered public accounting firm. However, the Board is submitting the selection of PricewaterhouseCoopers LLP to the stockholders for ratification as a matter of good corporate practice. If the stockholders fail to ratify the selection, the Audit Committee of the Board will reconsider whether or not to retain that firm. Even if the selection is ratified, the Audit Committee of the Board in its discretion may direct the appointment of different independent auditors at any time during the year if it determines that such a change would be in the best interests of the Company and its stockholders. Representatives of PricewaterhouseCoopers LLP are expected to be present at the Annual Meeting, and will have the opportunity to make statements if they desire to do so and to respond to appropriate questions.

        The affirmative vote of the holders of a majority of the votes present either in person or by proxy at the Annual Meeting will be required to ratify the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2017. Abstentions will be counted as present for purposes of determining the presence of a quorum and therefore will have the same effect as a vote "Against" this proposal.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS
A VOTE "FOR" THE RATIFICATION THE APPOINTMENT OF PRICEWATERHOUSECOOPERS LLP
AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE FISCAL YEAR ENDING
DECEMBER 31, 2017.

PROPOSAL 3
APPROVAL OF AN AMENDMENT TO THE COMPANY'S CERTIFICATE OF INCORPORATION TO DECLASSIFY THE BOARD OF DIRECTORS AND PROVIDE FOR THE ANNUAL ELECTION OF DIRECTORS

        As part of the Nominating and Corporate Governance Committee's review of the Company's corporate governance guidelines and periodic review of the size, structure, composition and functioning of the Board, and after reviewing the various arguments for and against a classified board structure and discussing with various of the Company's stockholders, the Committee recommended that the Board approve an amendment to our Certificate of Incorporation to eliminate the classification of the Board of Directors over a three-year period so that beginning at the 2020 Annual Meeting of Stockholders all directors would be elected for a one-year term.

        On April 10, 2017, the Board of Directors adopted an amendment to our Certificate of Incorporation (the "Declassification Amendment") which would phase out the classification of the Board, and which is subject to approval of this proposal. The Board further directed that the proposed Declassification Amendment be submitted for consideration by our stockholders at the Annual Meeting. We are asking stockholders to approve the Declassification Amendment.

        Article VI, Section B of our Certificate of Incorporation currently provides that the Company's directors are divided into three classes, with the term of one class expiring each year and the directors in each class serving three-year terms. If the Declassification Amendment is approved and becomes effective, directors elected at this Annual Meeting, or the terms of classes elected in 2016 and 2015 will continue to serve out their three-year terms, but directors elected after the Annual Meeting will be elected to one-year terms. Therefore, beginning with the 2020 Annual Meeting of Stockholders, the Board of Directors will be declassified and the entire Board will be elected on an annual basis.

        The Declassification Amendment would not change the present number of directors or the Board's authority to change that number and to fill any vacancies or newly created directorships. Until the 2020 Annual Meeting of Stockholders, any director appointed to fill newly created Board seats or vacancies would hold office for a term that coincides with the remaining term of the relevant class and upon the annual election of the entire Board at the 2020 Annual Meeting of Stockholders, a director appointed to a vacancy or new directorship would serve for a term expiring at the next annual meeting of stockholders following his or her appointment. In addition, because our Board is classified, our Certificate of Incorporation currently provides that directors may be removed only for cause, consistent with Delaware law. The Declassification Amendment provides that directors elected to serve a three-year term may only be removed for cause and that from and after the 2020 Annual Meeting, when declassification is complete, all directors may be removed either with or without cause. A full text of the Declassification Amendment is attached to this Proxy Statement as Appendix A.

        If the Declassification Amendment is approved, the Board intends to cause the Declassification Amendment to be filed with the Secretary of State of the State of Delaware following the Annual Meeting and adopt conforming amendments, if necessary, to the Company's Amended and Restated Bylaws and Corporate Governance Guidelines. Even if the Declassification Amendment is approved, the Board reserves the right not to effect the filing of the Declassification Amendment with the Secretary of State of the State of Delaware if the Board determines it not to be in the best interests of the Company and its stockholders to effect the declassification of the Board. If the Declassification Amendment is not approved, our Board will remain classified.

        The approval of this proposal will require the affirmative vote of the holders of at least two-thirds of all outstanding shares of common stock of the Company entitled to vote generally in the election of directors. In determining whether this proposal has received the requisite number of affirmative votes, abstentions will not be counted and will have the same effect as a vote "Against" this proposal.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE "FOR" THE APPROVAL OF THE AMENDMENT TO DECLASSIFY THE BOARD OF DIRECTORS AND PROVIDE FOR THE ANNUAL ELECTION OF DIRECTORS.

PROPOSAL 4
ADVISORY APPROVAL OF THE COMPANY'S EXECUTIVE COMPENSATION
FOR THE YEAR ENDED DECEMBER 31, 2016

        In accordance with SEC rules, stockholders are being asked to approve, on a non-binding advisory basis, the compensation of our named executive officers for the year ended December 31, 2016 as disclosed in this proxy statement. This is commonly referred to as a "Say on Pay" proposal. While we are not required to conduct a "Say on Pay" vote at the Annual Meeting, our Board of Directors has decided to voluntarily conduct one at this time.

        This vote is not intended to address any specific item of compensation, but rather the overall compensation of our named executive officers and the philosophy, policies and practices described in this proxy statement. As described further in the "Executive Compensation" section of this Proxy Statement, beginning on page 25, including the "Compensation Discussion and Analysis" and the related tables and narrative, the primary goals of our compensation programs are to fairly compensation employees, attract and retain highly qualified employees, motivate the performance of our employees towards, and reward the achievement of, clearly defined corporate goals, and align our employees' long-term interests with those of our stockholders. We believe our compensation programs reflect a pay-for-performance philosophy that links potential significant compensatory rewards to achievement of corporate operating goals and increase in stockholder value.

        This Say on Pay vote is advisory, and therefore not binding on our Compensation Committee or Board of Directors. Our Board of Directors and our Compensation Committee value the opinions of our stockholders, however, and will carefully review and consider the voting results when evaluating our executive compensation programs.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS
A VOTE "FOR" ADVISORY APPROVAL OF THE COMPANY'S EXECUTIVE COMPENSATION

Appendix A

        The Amended and Restated Certificate of Incorporation of the Corporation is hereby further amended by deleting in its entirety Article VI of the Amended and Restated Certificate of Incorporation and inserting the following in lieu thereof:

ARTICLE VI

        A.    Subject to the rights of the holders of any series of Preferred Stock to elect additional directors under specified circumstances, the number of directors of the Corporation shall be fixed from time to time exclusively by the Board of Directors pursuant to a resolution adopted by a majority of the Whole Board and may not be fixed by any other person(s).

        B.    Commencing at the annual meeting of stockholders to be held in 2018 (each annual meeting of stockholders, an "Annual Meeting"), subject to the special rights of any series of Preferred Stock to elect additional directors under specified circumstances, the directors of the Corporation shall be elected annually and shall hold office until the next Annual Meeting and until his or her successor shall have been duly elected and qualified, or until such director's prior death, resignation, retirement, disqualification or other removal. Notwithstanding the preceding sentence, but subject to the rights, if any, of the holders of any series of the Preferred Stock then outstanding, any director in office at the 2018 Annual Meeting whose term expires at the 2019 Annual Meeting or the 2020 Annual Meeting (each such director, a "Continuing Classified Director"), shall continue to hold office until the end of the term for which such director was elected and until his or her successor shall have been duly elected and qualified, or until such director's prior death, resignation, retirement, disqualification or other removal.

        C.    Subject to the rights of the holders of any series of Preferred Stock then outstanding, newly created directorships resulting from any increase in the authorized number of directors or any vacancies in the Board of Directors resulting from death, resignation, retirement, disqualification, removal from office or other cause shall, unless otherwise provided by law or by resolution of the Board of Directors, be filled only by a majority vote of the directors then in office, though less than a quorum (and not by stockholders). Directors so chosen shall hold office until the next Annual Meeting and until his or her successor shall have been duly elected and qualified, or until such director's prior death, resignation, retirement, disqualification or other removal. Notwithstanding the foregoing, any director elected to fill a vacancy caused by the death, resignation, retirement, disqualification or removal of a Continuing Classified Director shall hold office until the Annual Meeting at which the term of such Continuing Classified Director would have expired and until his or her successor shall have been duly elected and qualified, or until such director's prior death, resignation, retirement, disqualification or other removal. No decrease in the authorized number of directors shall shorten the term of any incumbent director.

        D.    Advance notice of stockholder nominations for the election of directors and of business to be brought by stockholders before any meeting of the stockholders of the Corporation shall be given in the manner provided in the Bylaws of the Corporation.

        E.    Subject to the rights, if any, of any series of Preferred Stock then outstanding, any director, or the entire Board of Directors, may be removed from office at any time, with or without cause by the affirmative vote of the holders of a majority of the voting power of all of the then-outstanding shares of capital stock of the Corporation entitled to vote generally in the election of directors voting together as a single class. Notwithstanding the foregoing, to the fullest extent permitted by applicable law, until the expiration of the term of any director elected to serve a three-year term (or any director appointed to fill a vacancy caused by the death, resignation, retirement, disqualification or other removal of any such director) at the 2018 Annual Meeting, 2019 Annual Meeting or 2020 Annual Meeting, as the case may be, such director (or such director appointed to fill such vacancy) may be removed only for cause and only by the affirmative vote of the holders of a majority of the voting power of all of the then-outstanding shares of capital stock of the Corporation entitled to vote generally in the election of directors voting together as a single class.
