Item 1.    Business

Company Overview

        Boingo helps the world stay connected.

        We have established a global footprint of small cell networks that provide high-speed, high-bandwidth wireless Internet service to smartphones, tablet computers, laptops, and other wireless-enabled devices. Small cells are low-powered radio access nodes that operate in licensed and unlicensed spectrum that have a range of 10 meters to 1 to 2 kilometers. These small cell networks cover more than a million distributed antenna system (DAS) and Wi-Fi locations and reach more than one billion consumers annually. With the proliferation of mobile Internet-enabled wireless devices, and growth of high-bandwidth usage from streaming media and smartphone apps, we expect these small cells to play a significant role in helping meet the ever-increasing data demands of connected consumers who are accustomed to the benefits of broadband performance at home and work and are seeking the same applications, performance and availability on-the-go.

        Our small cell networks include DAS and Wi-Fi networks that we manage and operate ourselves, which we refer to as our "managed and operated" locations, as well as Wi-Fi networks managed and

2

operated by third-parties with whom we contract for access, which we refer to as our "roaming" networks. Our managed and operated locations are typically located in large venues with big audiences, such as airports, stadiums, arenas, universities, convention centers, shopping malls, and military bases where we install a wireless network infrastructure and generally have exclusive multi-year agreements. Our roaming networks comprise more than 800,000 commercial Wi-Fi hotspots in over 100 countries around the world. We also sell advertising and sponsorships on other Wi-Fi networks that are not part of our network on behalf of the network owner.

        We generate revenue through wholesale partnerships, retail sales, and advertising and sponsorships. We have direct customer relationships with users who have purchased our mobile Internet services, and we also provide mobile Internet access and solutions to our partners, which include telecom operators, cable companies, technology companies, enterprise software and services companies, and communications service providers to allow their millions of users to connect to the mobile Internet through hotspots in our network. Our software solution—which provides one-click access to our global footprint of hotspots—has been rebranded for wholesale partners, in addition to being marketed under the Boingo brand. In combination with our back-end system infrastructure, it creates a global roaming solution for operators, carriers and other service providers.

        We generate wholesale revenue from telecom operators that pay us build-out fees and recurring access fees so that their cellular customers may use our DAS networks at locations where we manage and operate the wireless network. In addition, our partners pay us usage-based Wi-Fi network access and software licensing fees to allow their customers' access to our footprint worldwide. Wholesale revenue accounts for approximately 47% of our revenue.

        Individual users provide approximately 42% of our revenue by purchasing month-to-month retail subscription plans that automatically renew, hotspot specific single-use access to our network, or residential broadband and Internet Protocol television ("IPTV") services in military barracks. As of December 31, 2013, we have grown our subscriber base to approximately 310,000, an increase of approximately 9.2% over the prior year.

        We also generate revenue from advertisers that seek to reach our users with sponsored access, promotional programs and online display advertising at locations where we manage and operate the Wi-Fi network and locations where we solely provide authorized access to a partner's Wi-Fi network through sponsored access and promotional programs. Advertising and other revenue accounts for approximately 11% of our revenue.

        We were incorporated in the State of Delaware in April 2001 under the name Project Mammoth, Inc. and changed our name to Boingo Wireless, Inc. in October 2001. Our principal executive offices are located in Los Angeles, California. Our website address is www.boingo.com. The information on, or that can be accessed through, our website is not part of this Annual Report on Form 10-K.

Industry Overview

        Popular business and consumer applications such as streaming media, online games, social networking, cloud storage, software-as-a-service and video calling require high-speed, high-bandwidth Internet access. These data-intensive applications are driving an escalation in Internet data traffic. With the proliferation of smartphones, tablet computers, laptops, and other Wi-Fi enabled devices, users expect to be able to access the same content and information while on-the-go. Global mobile data traffic is expected to increase by 11 times from 2013 to 2018 as projected by Cisco's Visual Networking Index ("CVNI").

        The adoption, growth and advancement of smartphones are key catalysts for the acceleration of high-speed and high-bandwidth mobile Internet usage. The improved computing power, rich graphical

3

user interfaces and Internet capabilities of these devices enable mobile users to make video calls or stream full-length movies, contributing to the vast expansion of the wireless consumption of data. For example, the average smartphone user generated 29 times the amount of data traffic generated by the average non-smartphone user in 2013, according to CVNI. Mobile video traffic was 53% of traffic by the end of 2013, according to CVNI. Widely-used mobile applications allow individuals to access the same content and services on their smartphones and other mobile devices that they use at their homes or offices. By the end of 2014, the number of mobile-connected devices will exceed the number of people on earth, and by 2018 there will be nearly 1.4 mobile devices per capita according to CVNI. In addition, 45% of total mobile data traffic was offloaded through Wi-Fi or other small cells in 2013 and without offload, mobile data traffic would have grown 98% rather than 81% in 2013, according to CVNI.

        To cope with the significant increase in expected global mobile Internet data traffic, network operators are rapidly expanding their capacity and investing in technologies such as 3G and 4G cellular networks. According to CVNI, a 4G connection generated 14.5 times more traffic on average than a non-4G connection and although 4G connections represent only 2.9% of mobile connections today, they already account for 30% of mobile data traffic. These investments, while necessary, are only a short-term solution not capable of meeting the long-term demand for data usage. To ease the strain of cellular networks by off-loading data, network operators have also been investing in Wi-Fi and cellular DAS that recycle spectrum in large venues to increase overall capacity. According to ABI Research, the market for in-building wireless equipment and deployments is expected to grow to over $8 billion in 2019, up from a forecast of $4.4 billion for 2014 representing a 14% compound annual growth rate.

        Wi-Fi provides higher speed and higher bandwidth per user in high density locations, and is simpler and less expensive to deploy than additional cellular network capacity. The benefits of and consumer demand for Wi-Fi have led hardware manufacturers to include Wi-Fi as a standard feature on laptops and tablet computers, and increasingly, smartphones, digital cameras and handheld media devices. Wi-Fi has become the standard protocol for residential and office wireless networks and is increasingly prevalent in public venues, such as airports, hotels, coffee shops, shopping malls, arenas, stadiums, campuses and quick service restaurants.

Challenges Facing Our Industry

        The mobile Internet is a complex and constantly evolving ecosystem comprised of over a billion mobile Internet-enabled devices from dozens of manufacturers, which are powered by many different operating systems. Devices use different network technologies and must be configured with the appropriate software to detect and optimize a connection to the mobile Internet. This complexity is amplified as new device models and operating systems are released, new categories of devices become Internet-enabled, and new network technologies emerge. The increasing number of mobile Internet-enabled devices in this ecosystem is causing an even more rapid increase in data consumption on capacity-strained networks.

Our Strategy

        We believe we are the leading global provider of commercial mobile Wi-Fi Internet solutions and indoor DAS services for carriers. Key elements of our strategy to extend that lead are to:

•

Expand our footprint of managed and operated and aggregated networks.  We intend to continue to grow our global network of managed and operated DAS and Wi-Fi networks by pursuing new opportunities at large venues such as airports, arenas, stadiums, campuses and universities. We also plan to enter into new roaming agreements with other network and hotspot operators to maximize the reach of our aggregated network, which creates a more attractive offering for our retail customers and wholesale partners.

•

Leverage our neutral-host business model to accelerate wholesale roaming and carrier offload partnerships.  Our neutral-host model enables us to partner with venue operators because we allow their customers to access a venue's network regardless of the customers' Wi-Fi provider. We also partner with telecom operators that are attracted to us because we do not compete for cellular subscribers. We intend to expand our neutral-host managed and operated network by partnering with additional venues, network operators, telecom operators and technology companies.

•

Maximize advertising and sponsorship sell-through for our inventory of advertising-enabled networks.  We will seek to leverage our expanded ad sales team to engage leading brands and advertising agencies acting on their behalf to maximize sell-through for our expanding inventory of advertising-supplemented managed and operated networks and contracted advertising-enabled partner networks. These networks represent high-traffic, high-demand locations with broad appeal. We also expect to enhance existing ad products and develop new ones to provide appealing options to advertisers looking for innovative ways to engage potential customers.

•

Increase our brand awareness.   We will continue to seek new ways to promote our brand through our managed and operated hotspots. We intend to enhance our brand through low-cost co-marketing arrangements with our partners and through periodic promotional and sponsorship activities and by continuing to leverage the reach of social media to interact with our customers.

Services

        Our solution makes it easy, convenient and cost effective for individuals to find and gain access to the mobile Internet.

        Wholesale.    Our integrated hardware and software platform allows us to provide a range of value-added services to telecom operators, network operators, device manufacturers, technology companies, enterprise software and services companies, and venue operators.

•

DAS infrastructure.  We offer our telecom operator partners access to our DAS infrastructure at certain of our managed and operated hotspot locations. We deploy our DAS infrastructure within airports and other locations that require additional signal strength to improve the quality of cellular services.

•

Roaming services.  We offer roaming services across our entire network of over 800,000 hotspot locations to our partners who can then provide mobile Internet services to their customers at these locations.

•

Platform services.  We license our proprietary software and provide software integration and development services to our platform services partners. This enables them to integrate our mobile Internet solution with their product and service offerings, either as a bundled Boingo service or a private labeled offering. Our solution includes our proprietary, patented techniques for wireless signal detection, presentation and network aggregation.

•

Turn-key solutions.  We offer our venue partners the ability to implement a turn-key Wi-Fi solution, with no initial investment, through a Wi-Fi network infrastructure that we install, manage and operate. Our turn-key solutions include a variety of service models that are supported through a mix of retail, wholesale and advertising revenue.

        Retail.    We enable individuals to purchase mobile Internet access at our managed and operated hotspots and select partner locations around the world. We offer a selection of month-to-month subscription and single-use access plans. Our most common plans are the $9.95 month-to-month subscription, the $7.95 month-to-month smartphone only subscription and the single-use Boingo AsYouGo at $7.95 per day. Our single-use access plans provide unlimited access to a specific hotspot

We provide advertisers the opportunity to sponsor wireless Internet access to individuals at locations where we manage and operate the Wi-Fi network and locations where we solely provide authorized access to a partner's Wi-Fi network through sponsored access and promotional programs. We also offer display advertising based on impressions delivered by our platform. Our advertising solution is easily integrated into Wi-Fi networks not directly managed by Boingo, expanding the addressable market.

Our Network

        In 2006, we acquired Concourse Communications Group, LLC and its network of 12 managed and operated airports, which became our first managed and operated hotspots. In 2007, we acquired Sprint Spectrum's network of seven managed and operated airports and one non-exclusive airport. In 2008, we acquired Opti-Fi Networks, LLC which included Wi-Fi networks at 25 airports and the Washington State Ferries. In 2013, we acquired Electronic Media Systems, Inc. and Advanced Wireless Group, LLC and its network of 17 managed and operated networks (collectively, "AWG"). Through our managed and operated hotspots and our strategic partnership arrangements, users have access to over 800,000 hotspots worldwide in venues such as airports, hotels, coffee shops, shopping malls, arenas, stadiums and quick service restaurants. We design, build, monitor and maintain the Wi-Fi network at our managed and operated hotspot locations primarily located in the United States and Europe. Our strategic partnership arrangements with over 170 network operators allow us to extend our global network to over 100 countries worldwide.

Marketing and Business Development

        Our marketing and business development efforts are designed to cost effectively attract and retain new customers, expand our footprint of Wi-Fi hotspot, DAS and advertising locations and identify business partners that could leverage our network to provide mobile Internet services to their customers. We focus on efficient customer acquisition and brand building through our on-line presence, in-venue signage, public relations, market research and other promotional activities.

        We seek to maximize customer lifetime value by managing subscriber acquisition cost, extending customer life and determining appropriate pricing. We use information about subscriber behavior to help us retain customers and determine premium offerings. Our segmentation is focused at the product level, so that we provide the right product, plan and price for each customer in each region of the world where we operate. Our consumer plans are available for essentially all Wi-Fi enabled devices and are priced on a month-to-month or per-use basis.

        We issue regular press releases announcing important partnerships and product developments and continually update our website with information about our network and services. We leverage our blog and social media accounts to further promote Boingo's product availability and applicability for travelers, digital elite and consumers on-the-go.

Development

        Our development efforts are focused primarily on increasing the ease of use and functionality of our software client, integrating our software client with our wholesale partners, continuing to adapt our technology to new operating systems and platforms, and optimizing our networks and backend systems for roaming and carrier offload. Our development model is based on a structured development process that incorporates Agile development practices so any deviations can be promptly corrected to improve reliability in our network and enhance customer satisfaction. We typically deliver product releases and feature enhancements on a semi-annual basis. For the years ended December 31, 2013, 2012 and 2011, development and technology expenses were $11.4 million, $10.8 million and $9.4 million, respectively.

Technology

        Over the past 13 years, we have developed proprietary systems that include the Boingo software client; authentication, authorization and tracking systems; mediation and billing systems; and a real-time operational support and software configuration and messaging infrastructure.

7

Boingo Software Client

        The Boingo software client is installed on Wi-Fi enabled devices such as smartphones, laptops and tablet computers to enable our customers to access our network. The key features of the Boingo software client include:

•

Simple user interface.  The Boingo software client provides individuals with an uncomplicated, user-friendly interface designed to streamline the Wi-Fi network connection process. The software finds hotspots and monitors the availability of Wi-Fi hotspots in the Boingo network, presents a notification message of the hotspot identified and allows one-click user connections. In some devices, connection to a Boingo Wi-Fi hotspot occurs in the background, providing the user with a seamless, notification-free connectivity experience.

•

Support for all major operating system platforms.  The Boingo software client supports the Android, iOS, Mac OS and Windows operating systems, which represents the majority of all devices connecting to our managed and operated venues.

•

Automatic updates.  The Boingo software client automatically receives identification information for new hotspot locations as they are added to the Boingo network, including any information needed to automatically identify and login to the network. Location information, allowing a user to find Boingo hotspots from the client, is also automatically updated. On all but embedded platforms, software updates are also automatically offered to a user when available.

•

Custom branding and flexible integration alternatives.  We offer wholesale customers the ability to integrate the Boingo software client into their products and services as a software development kit or SDK. Additionally, we offer wholesale customers the option to utilize a custom, rebranded reference design of the software client used in our retail customer offering.

Authentication, Authorization and Tracking System

        Our proprietary authentication, authorization and tracking system enables the reliable, scalable and secure initiation and termination of user Wi-Fi sessions on our network. This system authenticates our network users across a wide variety of hotspots and network operators, through a normalized authentication protocol. Through the authorization process, custom business rules ensure user access based on specific service parameters such as location, type of device, service plan and account information. Our system also captures duration, data traffic, location, and type of device. We normalize and process this data from disparate providers for our use and for our wholesale partners. This system has been recently enhanced to include support for secure Next Generation Hotspot roaming, which leverages Passpoint-certified devices and network hardware to establish seamless secure connections for customers.

Mediation and Billing System

        Our mediation and billing system records and analyzes individual usage sessions required to bill for Wi-Fi usage. Users are charged based on variables such as pricing plan, device type, location, time and amount of use. Our system consolidates usage session information, determines the user identity and applies the appropriate aggregation and flagging to ensure proper usage processing. Our system handles exceptions automatically. Exceptions that cannot be solved automatically are brought to the attention of the operations staff, who rectifies any discrepancies. The billing system provides billing based on roaming relationship, user type, device type and account type. Our retail customer mediation and billing is handled by the same infrastructure used for wholesale customer and billing, resulting in efficiencies of scale and operation.

8

Software Configuration and Messaging System

        Our software configuration system provides real-time network configuration updates for approximately 2,320 networks and 87 detection and login methodologies used by the Boingo software client to access our network. Our software configuration system automatically registers new network definitions and login methodologies to allow individuals to connect to our hotspot locations. All supported platforms use a single configuration, providing a high level of operational and test efficiency. Our messaging system enables real-time customer notification and system interaction at login, based on location, network, user, account type, device and usage. This approach enables us and our partners to deliver custom marketing or service messages.

Operations

        We provide significant operational support for our managed and operated Wi-Fi hotspots and other hotspots in our network. For our managed and operated Wi-Fi hotspots, we design, build, monitor and maintain the network. For roaming partners, we monitor hotspot uptime and report outages so that they can be quickly remedied. We have service level agreements with our roaming partners specifying minimum network uptime requirements.

        Our Wi-Fi deployments are based on the IEEE 802.11a, b, g, n and ac standards and operate in the 2.4 GHz and 5 GHz unlicensed spectrum bands. Our deployments may also include DAS within venues requiring enhanced cellular coverage.

Customers

        We generate revenue primarily from our retail customers and wholesale partners. Our retail customers purchase either month-to-month subscription plans that automatically renew, or single-use access to our network. We acquire our retail customers primarily from mobile Internet users passing through our managed and operated locations, where we generally have exclusive multi-year agreements. Some of our wholesale partners license our software and pay usage-based network access fees to allow their customers access to our global Wi-Fi network. Other wholesale partners that are telecom operators pay us one-time build-out fees and recurring access fees for our DAS network, enabling their cellular customers to access these networks. Some of our wholesale partners pay us to provide Wi-Fi services in their venue locations under a service provider arrangement. Our wholesale partner relationships are generally governed by multi-year contracts. We acquire our wholesale partners through our business development efforts. We also generate revenue from advertisers that seek to reach visitors to the landing pages at our managed and operated network locations with online advertising, promotional and sponsored programs. For the year ended December 31, 2013, two groups of entities affiliated with Verizon Communications, Inc and AT&T Inc. each accounted for 14% of total revenue. For the year ended December 31, 2012, those same two groups of affiliated entities accounted for 17% and 15% of total revenue, respectively. For the year ended December 31, 2011, one group of entities affiliated with Verizon Communications, Inc. accounted for 18% of total revenue. The loss of these groups and the customers could have a material adverse impact on our consolidated statements of operations.

Key Business Metrics

        In addition to monitoring traditional financial measures, we also monitor our operating performance using the following key performance indicators:

	Year Ended December 31,
	2013			2012			2011
	(in thousands, except churn data)
Subscribers		310			284			257
Monthly churn		10.1	%		9.7	%		9.2	%
Connects		50,830			24,490			12,314
DAS nodes		6.3			5.6			4.6

        Subscribers.    This metric represents the number of paying retail customers who are on a month-to-month subscription plan at a given period end.

        Monthly churn.    This metric shows the number of subscribers who canceled their subscriptions in a given month, expressed as a percentage of the average subscribers in that month. The churn in a given period is the average monthly churn in that period. This measure is one indicator of the longevity of our subscribers. Some of our customers who cancel subscriptions maintain accounts for single-use access.

        Connects.    This metric shows how often individuals connect to our global Wi-Fi network in a given period. The connects include retail and wholesale customers in both customer pay locations and customer free locations where we are a paid service provider or receive sponsorship or promotional fees. We count each connect as a single connect regardless of how many times that individual accesses the network at a given venue during their 24 hour period. This measure is an indicator of paid activity throughout our network.

        DAS nodes.    This metric represents the number of active DAS nodes as of the end of the period. A DAS node is a single communications endpoint, typically an antenna, which transmits or receives radio frequency signals wirelessly. This measure is an indicator of the reach of our DAS network.

Retail Customer Support Services

        We provide support services to our retail customers 24 hours per day, 7 days per week, 365 days per year, by phone, chat or email. Our website also contains a comprehensive list of responses to frequently asked questions, and we monitor and respond to social media communications regarding our services. We provide support services through our internal customer care department and we rely on a third-party provider for most of our standard customer support.

Competition

        The market for mobile Internet services and solutions is fragmented and competitive. We believe the principal competitive factors in our industry include the following:

•

price;

•

ease of access and use;

•

quality of service;

•

geographic reach;

•

bundled service offerings;

•

venue exclusivity;

•

brand name recognition; and

10

•

flexible pricing plans.

        We believe we face no material direct competitors to our service offerings. Indirect competitors include telecom operators, WiMAX operators, cable companies, self-managed venue networks and smaller wireless Internet service providers. Some of these competitors have substantially greater resources, larger customer bases, longer operating histories and greater name recognition than we have. Others offer bundled data services with primary service offerings that we do not offer such as landline and cellular telephone service, and cable or satellite television. Many of our indirect competitors are also partners from whom we receive revenue when their customers access our network. We believe that we compete favorably based on geographic coverage, network reliability, quality of service, ease of use and cost.

Intellectual Property

        Our ongoing success will depend in part upon our ability to protect our core technology and intellectual property. To accomplish this, we rely on a combination of intellectual property rights, including trade secrets, patents, copyrights and trademarks, as well as contractual restrictions.

        We have two issued U.S. patents which expire in 2022 and six patent applications pending in the U.S. Foreign counterparts of two of the pending U.S. patent applications are pending in Canada, Europe and Korea. Foreign counterparts of another one of the pending U.S. patent applications are pending in Canada, China, Europe, Japan, and Korea. We have two issued Japanese patents and two Chinese patents, each of which has a maximum term which expires in 2027. We intend to pursue corresponding patent coverage in additional countries to the extent we believe such coverage is appropriate and cost effective.

        Our registered trademarks in the United States and the European Union include "Boingo", "Boingo Wi-Finder", and "Don't just go. Boingo.", and in the United States, "Cloud 9 Media". We own additional registrations and have filed other trademark applications in the United States and other countries.

        In addition to the foregoing protections, we control access to, and use of, our proprietary software and other confidential information through the use of internal and external controls, including contractual protections with employees, contractors, customers and partners. Our software is protected by United States and international copyright laws.

Employees

        As of December 31, 2013, we had 204 employees, including 60 in development and technology, 100 in operations, 23 in business development and marketing and 21 in general and administrative. All of our employees are full-time employees. None of our employees are represented by a labor union except for one international employee who is covered by a collective bargaining agreement. We have never experienced any employment related work stoppages and consider relations with our employees to be good. As of December 31, 2013, we also had arrangements with a third party call center provider in New York that provided us with approximately 35 full-time equivalent contractors for retail customer support service and similar functions.

Item 1A.    Risk Factors

Investing in our common stock involves a high degree of risk. You should consider carefully the risks and uncertainties described below, together with all of the other information in this report on Form 10-K, including our accompanying consolidated financial statements and the related notes, before deciding whether to purchase shares of our common stock. If any of the following risks actually occur, our business, financial condition, results of operations and prospects could be materially and adversely affected. The price of our common stock could decline and you could lose part or all of your investment.

Risks Related to Our Business

         A significant portion of our revenue is dependent on our relationships with our venue and network partners, and if these relationships are impaired or terminated, or if our partners do not perform as expected, our business and results of operations could be materially and adversely affected.

        We depend on our relationships with venue partners, particularly key airport venue partners, in order to manage and operate Wi-Fi hotspots. These relationships generate a significant portion of our revenue and allow us to generate new retail customers. Our agreements with our venue partners are for defined periods and of varying durations. If our venue partners terminate or fail to renew these agreements, our ability to generate and retain retail customers would be diminished and our network of Wi-Fi hotspots would be reduced, which might result in a significant disruption of our business and adversely affect our operating results.

        We depend on our relationships with network partners to allow users to roam across Wi-Fi networks that we do not manage or operate. A significant portion of our revenue depends on maintaining these relationships with network partners. Some network partners may compete with us for retail customers and may decide to terminate our partnerships and instead develop competing retail products and services. Our network partner agreements are for defined periods and of varying durations. If our network partners terminate these agreements, or fail to renew these agreements, our ability to retain retail customers could be diminished and our network of Wi-Fi hotspots could be reduced, which could result in a significant disruption of our business and adversely affect our operating results.

         Worldwide economic conditions, and their impact on travel and consumer spending, may adversely affect our business, operating results and financial condition.

        Global economic conditions have been weak for a prolonged period of time, and levels of travel and consumer spending have been particularly depressed. Our business is impacted by travel and consumer spending, because users seek to access the mobile Internet while they are on-the-go, and because spending on Internet access is often a consumer discretionary spending decision. Factors that

12

tend to negatively impact levels of travel include high unemployment, high energy prices, low business and consumer confidence, the fear of terrorist attacks, war and other macroeconomic factors. Economic conditions that tend to negatively impact levels of discretionary consumer spending include high unemployment, high consumer debt, reductions in net worth, depressed real estate markets, increased taxation, high energy prices, high interest rates, low consumer confidence and other macroeconomic factors. If the global economic recovery is slower than expected, or if it weakens, our retail customer base, new retail customer acquisition and usage-based revenue could be materially harmed, and our results of operations would be adversely affected.

         Our business depends upon demand for mobile Internet services on Wi-Fi networks, market adoption of new technologies and our ability to adapt to such changes.

        Our future success depends upon growing demand for mobile Internet services, which is inherently uncertain. The demand for mobile Internet services may decrease or may grow more slowly than expected. Any such decrease in the demand or slowing rate of growth could have a material adverse effect on our business. The continued demand for mobile Internet services depends on the continued proliferation of smartphones, tablet computers and other Wi-Fi enabled devices and the rate of evolution of data-intensive applications on the mobile Internet. Historically, we have derived substantially all our retail revenue from laptop users who purchased month-to-month subscriptions or single-use access. We may face challenges as we seek to increase the revenue generated from the usage on smartphones, tablet computers and other mobile devices.

        Our business depends on the continued integration of Wi-Fi as a standard feature in mobile devices. If Wi-Fi ceases to be a standard feature in mobile devices, or if the rate of integration of Wi-Fi on mobile devices decreases or is slower than expected, the market for our services may be substantially diminished.

        Competing technologies pose a risk to the continued use of Wi-Fi as a mobile Internet technology. The introduction and market acceptance of emerging wireless technologies such as 4G, WiMAX and Super Wi-Fi, could cause significant disruption to our business, which may result in a loss of customers, users and revenue. If users find emerging wireless technologies to be sufficiently fast, convenient or cost effective, we may not be able to compete effectively, and our ability to attract or retain users will be impaired. Additionally, one or more of our partners may deploy emerging wireless technologies that could reduce the partner's need to work with us, and may result in significant loss of revenue and reduction of the hotspots in our network.

        We deliver value to our users by providing simple access to Wi-Fi hotspots, regardless of whether we manage and operate the hotspot, or the hotspot is operated by a partner. As a result, our business depends on our ability to anticipate and quickly adapt to changing technological standards and advances. If technological standards change and we fail to adapt accordingly, our business and revenue may be adversely affected. Furthermore, the proliferation of new mobile devices and operating platforms poses challenges for our research and development efforts. If we are unable to create simple solutions for a particular device or operating platform, we will be unable to effectively attract users of these devices or operating platforms and our business will be adversely affected.

         The growth of free Wi-Fi networks may compete with our paid mobile Wi-Fi Internet solutions.

        Many venues, including airports, coffee shops and hotels, offer free mobile Wi-Fi as an incentive or value-added benefit to their customers. Free Wi-Fi may reduce retail customer demand for our services, and put downward pressure on the prices we charge our retail customers. In addition, telecom operators may offer free mobile Wi-Fi as part of a home broadband or other service contract, which also may force down the prices we charge our retail customers. If we are unable to effectively offset this downward pressure on our prices by being a Wi-Fi service provider, or if we are unable to acquire and retain retail customers, we will have lower profit margins and our operating results and financial condition may be adversely impacted.

13

         Negotiations with prospective wholesale partners can be lengthy and unpredictable, which may cause our operating results to vary.

        Our negotiations with prospective partners to acquire Wi-Fi hotspots to operate, to acquire roaming rights on partners' networks, or for new partners to implement our solutions, can be lengthy, and in some cases can last over 12 months. Because of the lengthy negotiation cycle, the time required to reach a final agreement with a partner is unpredictable and may lead to variances in our operating results from quarter to quarter. Negotiations with prospective partners also require substantial time, effort and resources. We may ultimately fail in our negotiations, resulting in costs to our business without any associated benefits.

         We may be unsuccessful in expanding into new venue types, which could harm the growth of our business, operating results and financial condition.

        We are negotiating with existing and prospective partners to expand our managed and operated Wi-Fi network footprint in venue types where we historically have had only a limited presence. Expansion into these venue types, and in particular shopping malls, stadiums and quick service restaurants, may require significantly higher initial capital expenditures than we have historically incurred. In contrast to Wi-Fi network build-outs at venues such as airports, where telecom operators typically pay the substantial expense of laying cable or fiber, we may be required to incur the initial capital expense of access points and related hardware and cabling at tens of thousands of quick serve restaurant locations and hundreds of shopping malls and stadium locations. We may not be able to execute on our strategy or there may not be returns on these investments in the near future or at all. As a result, our business, financial condition and results of operations could be materially and adversely affected.

         We have a limited operating history and a relatively new business in an emerging market, so an investment in our company involves more risk than an investment in a more mature company in an established industry.

        We have a limited operating history with the mobile Wi-Fi Internet solutions that we provide, which were developed in 2001. We currently attract the majority of our retail customers at our managed and operated hotspots that we acquired in 2006. As a result, we have a limited operating history for you to evaluate in assessing our future prospects and it is difficult to forecast our prospects. Also, we derive nearly all of our revenue from mobile Internet services, which are new and highly dynamic businesses, which face significant challenges. You should consider our business and prospects in light of the risks, uncertainties and difficulties we will encounter as an emerging company in a new and rapidly evolving market. We may not be able to address these risks, uncertainties and difficulties successfully, which could materially harm our business and operating results.

         Our operating results may fluctuate unexpectedly, which makes them difficult to predict and may cause us to fail to meet the expectations of investors, adversely affecting our stock price.

        We operate in a highly dynamic industry and our future quarterly operating results may fluctuate significantly. Our revenue and operating results may vary from quarter to quarter due to many factors, many of which are not within our control. As a result, comparing our operating results on a period-to-period basis may not be meaningful. Further, it is difficult to accurately forecast our revenue, margin and operating results, and if we fail to match our expected results or the results expected by financial analysts, the trading price of our common stock may be adversely affected.

        Factors that contribute to fluctuations in our operating results from quarter-to-quarter include those described in this risk factor section including:

•

our gain or loss of a key venue partner, military partner, roaming partner or platform services partner;

14

•

the rate at which individuals adopt and continue to use our solutions;

•

the timing and success of new technology introductions by us or our competitors;

•

the growing prevalence of free Wi-Fi models and our ability to adapt and compete with free Wi-Fi;

•

the number of air travel passengers, particularly business travelers;

•

intellectual property disputes; and

•

general economic conditions in our domestic and foreign markets.

        Due to these and other factors, quarter-to-quarter comparisons of our historical operating results should not be relied upon as accurate indicators of our future performance.

         We may not maintain recent rates of revenue growth.

        Although our revenue has increased substantially over the last few years, we may not be able to maintain historical rates of revenue growth. We believe that our continued growth will depend, among other factors, on successfully implementing our business strategies, including our ability to:

•

attract new users, convert users of our single-use services into subscribers and keep existing subscribers actively using our services;

•

develop new sources of revenue from our users and partners;

•

react to changes in the way individuals access and use the mobile Internet;

•

expand into new markets;

•

increase the awareness of our brand;

•

retain our existing partners and attract new partners; and

•

provide our users with a superior experience, including customer support and payment experiences.

        However, we cannot guarantee that we will successfully implement any of these business strategies.

         The U.S. government may modify, curtail or terminate one or more of our contracts.

        We have dedicated a significant amount of resources to building out residential broadband and IPTV networks for troops stationed on military bases pursuant to our contracts with the U.S. government. The investment of these resources will occur in advance of experiencing any direct benefit from them including generation of revenues and will make it difficult to determine if we are allocating our resources efficiently. As a result of these investments, we do not expect to be profitable in the near future. The U.S. government may modify, curtail or terminate its contracts with us, either at its convenience or for default based on performance. Any such modification, curtailment, or termination of one or more of our government contracts could have a material adverse effect on our earnings, cash flow and/or financial position.

         System failures could harm our business.

        Although we seek to reduce the possibility of disruptions or other outages, our business may be disrupted by problems with our technology and systems, such as an access point failure at one of our managed and operated hotspots, or a backhaul disruption. We have experienced system failures from time to time, and any interruption in the ability of users to access our solution could harm our business and reputation.

        Our systems may be vulnerable to damage or interruption from telecommunications failures, computer denial-of-service attacks, power loss, computer viruses, earthquakes, floods, fires, terrorist attacks and similar events. Some of our systems are not fully redundant, and our disaster recovery

15

planning is not sufficient for all eventualities. Our systems may also be damaged by break-ins, sabotage, and acts of vandalism. Despite any precautions we may take, the occurrence of a natural disaster or other unanticipated problems could result in lengthy interruptions in the availability of the Boingo solution. We do not carry business interruption insurance to compensate us for all losses that may result from service interruptions caused by system failures. If we are unable to resolve service interruptions quickly, our ability to acquire and retain customers will be impaired and our operating results and business could be adversely affected.

         We may be unsuccessful in expanding our international operations, which could harm the growth of our business, operating results and financial condition.

        Our ability to expand internationally involves various risks, including the need to invest significant resources in unfamiliar markets, and the possibility that there may not be returns on these investments in the near future or at all. In addition, we have incurred and expect to continue to incur expenses before we generate any material revenue in these new markets. Our expansion plans will require significant management attention and resources. We have limited experience in selling our solutions in international markets or in conforming to local cultures, standards or policies. We may not be able to compete successfully in these international markets. Our ability to expand will also be limited by the demand for mobile Internet in international markets. Different privacy, censorship and liability standards and regulations and different intellectual property laws in foreign countries may cause our business and operating results to suffer.

        Any future international operations may fail to succeed due to risks inherent in foreign operations, including:

•

different technological solutions for mobile Internet than those used in North America;

•

varied, unfamiliar and unclear legal and regulatory restrictions;

•

unexpected changes in international regulatory requirements and tariffs;

•

legal, political, social or systemic restrictions on the ability of U.S. companies to do business in foreign countries;

•

Foreign Corrupt Practices Act compliance and related risks;

•

difficulties in staffing and managing foreign operations;

•

difficulties in enforcing contracts and collecting accounts receivable, and longer payment cycles, especially in emerging markets;

•

reduced protection for intellectual property rights in some countries;

•

currency fluctuations; and

•

potential adverse tax consequences.

        Some of our business partners also have international operations and are subject to the risks described above. Even if we are able to successfully manage the risks of international operations, our business may be adversely affected if our business partners are not able to successfully manage these risks.

        As a result of these obstacles, we may find it difficult or prohibitively expensive to expand internationally or we may be unsuccessful in our attempt to do so, which could harm our business, operating results and financial condition.

         Our industry is competitive and if we do not compete successfully, we could lose market share, experience reduced revenue or suffer losses.

        The market for commercial mobile Wi-Fi solutions is competitive and impacted by technological change, and we expect competition with our current and potential competitors to intensify in the

16

future. In particular, some of our competitors have taken steps or may decide to more aggressively compete against us, particularly in the market for venue build-outs of Wi-Fi and DAS solutions.

        Our competitors, many of whom are also our partners, include a variety of telecom operators and network operators, including AT&T, T-Mobile, Cablevision, Comcast and local operators. These and other competitors have developed or may develop technologies that compete directly with our solutions. Many of our competitors are substantially larger than we are and have substantially longer operating histories. We may not be able to fund or invest in certain areas of our business to the same degree as our competitors. Many have substantially greater product development and marketing budgets and other financial and personnel resources than we do. Some also have greater name and brand recognition and a larger base of subscribers or users than we have. In addition, our competitors may provide services that we do not, such as cellular, local exchange and long distance services, voicemail and digital subscriber line. Users that desire these services may choose to also obtain mobile Wi-Fi Internet services from a competitor that provides these additional services rather than from us.

        Furthermore, we rely on several of our competitors as partners in roaming agreements. The roaming agreements provide that our retail customers and our wholesale partners' customers may use the Wi-Fi networks of our partners. One or more of our partners may deploy competing technologies that could reduce the partner's need to work with us under a roaming agreement. If our partners decide to terminate our roaming agreements, our network of Wi-Fi hotspots may be reduced, which may result in a significant disruption to our business.

        Competition could increase our selling and marketing expenses and related customer acquisition costs. We may not have the financial resources, technical expertise or marketing and support capabilities to continue to compete successfully. A failure to respond to established and new competitors may adversely impact our business and operating results.

         The regulation of Internet communications, products and services is currently uncertain, which poses risks for our business from changes in laws, regulations, and interpretation or enforcement of existing laws or regulations.

        The current regulatory environment for Internet communications, products and services is uncertain. Many laws and regulations were adopted prior to the advent of the Internet and related technologies and often do not contemplate or address the specific issues associated with the Internet and related technologies. The scope of laws and regulations applicable to the Internet remains uncertain and is subject to statutory or interpretive change. We cannot be certain that we, our partners or our users are currently in compliance with regulatory or other legal requirements in the numerous countries in which our service is used. Our failure or the failure of our partners, users and others with whom we transact business, or to whom we license the Boingo solution, to comply with existing or future regulatory or other legal requirements could materially adversely affect our business, financial condition and results of operations. Regulators may disagree with our interpretations of existing laws or regulations or the applicability of existing laws or regulations to our business, and existing laws, regulations and interpretations may change in unexpected ways.

        We believe that the Boingo solution is on the forefront of mobile Internet technology, and therefore it may face greater regulatory scrutiny than other communications products and services. We cannot be certain what positions regulators may take regarding our compliance with, or lack of compliance with, current and future legal and regulatory requirements or what positions regulators may take regarding any past or future actions we have taken or may take in any jurisdiction. Regulators may determine that we are not in compliance with legal and regulatory requirements, and impose penalties, or we may need to make changes to the Boingo solution, which could be costly and difficult. Any of these events would adversely affect our operating results and business.

17

         If we lose key personnel or are unable to attract and retain personnel on a cost effective basis, our business could be harmed.

        Our performance is substantially dependent on the continued services and performance of our senior management and our highly qualified team of engineers, many of whom have numerous years of experience and specialized expertise in our business. If we are not successful in hiring and retaining highly qualified engineers, we may not be able to extend or maintain our engineering and technological expertise and our future product and service development efforts could be adversely affected. If we lose members of our senior management, this may significantly delay or prevent the achievement of our strategic objectives and adversely affect our operating results.

        Our future success also depends on our ability to identify, attract, hire, train, retain and motivate highly skilled managerial, operations, business development and marketing personnel. We have in the past maintained a rigorous, highly selective and time-consuming hiring process. We believe that our approach to hiring has significantly contributed to our success to date. However, our highly selective hiring process has made it more difficult for us to hire a sufficient number of qualified employees, and, as we grow, our hiring process may prevent us from hiring the personnel we need in a timely manner. Moreover, the cost of living in the Los Angeles area, where our corporate headquarters is located, has been an impediment to attracting new employees in the past, and we expect that this will continue to impair our ability to attract and retain employees in the future. If we fail to attract, integrate and retain the necessary personnel, we may not be able to grow effectively and our business could suffer significantly.

         Our failure to properly maintain our customers' confidential information and protect our network against security breaches, including cyber-security breaches, could harm our business and operating results.

        Advances in computer capabilities, new discoveries in the field of cryptography or other cyber-security developments may result in a compromise or breach of the technology we use to protect user transaction data. Cyber-security risks such as malicious software and attempts to gain unauthorized access to data are rapidly evolving and could lead to disruptions in our network, unauthorized release of confidential or otherwise protected information or corruption of data. Any compromises of our security could damage our reputation and brand and expose us to possible liability such as litigation claims, which would substantially harm our business and operating results. We may need to expend significant resources to protect against security breaches or to address problems caused by breaches.

        Many countries, such as European Union member states as a result of the 2006 E.U. Data Retention Directive, are introducing, or have already introduced into local law some form of traffic and user data retention requirements, which are generally applicable to providers of electronic communications services. Retention periods and data types vary from country to country, and the various local data protection and other authorities may implement traffic and user retention requirements regarding certain data in different and potentially overlapping ways. Although the constitutionality of the 2006 E.U. Data Retention Directive has been questioned, we may be required to comply with data retention requirements in one or more jurisdictions, or we may be required to comply with these requirements in the future as a result of changes or modifications to the Boingo solution or changes or modifications to the technological infrastructure on which the Boingo solution is based. Failure to comply with these retention requirements may result in the imposition of costly penalties. Compliance with these retention requirements can be difficult and costly from a legal, operational and technical perspective and could harm our business and operational results.

         We rely on a third-party customer support service provider for the majority of our customer support calls. If this service provider experiences operational difficulties or disruptions, our business could be adversely affected.

        We depend on a third-party customer support service provider to handle most of our routine retail customer support cases. While we maintain limited customer support operations in our Los Angeles

18

headquarters, if our relationship with our customer support service provider terminates unexpectedly, or if our customer service provider experiences operational difficulties, we may not be able to respond to customer support calls in a timely manner and the quality of our customer service would be adversely affected. This could harm our reputation and brand image and make it difficult for us to attract and retain users. In addition, the loss of the customer support service provider would require us to identify and contract with alternative sources, which could prove time-consuming and expensive.

         Material defects or errors in our software could harm our reputation, result in significant costs to us and impair our ability to sell the Boingo solution.

        The software underlying the Boingo solution is inherently complex and may contain material defects or errors, particularly when the software is first introduced or when new versions or enhancements are released. We have from time to time found defects or errors in our software, and defects or errors in our existing software may be detected in the future. Any defects or errors that cause interruptions to the availability of our services could result in:

•

a reduction in sales or delay in market acceptance of the Boingo solution;

•

sales credits or refunds to our users and wholesale partners;

•

loss of existing users and difficulty in attracting new users;

•

diversion of development resources;

•

harm to our reputation and brand image; and

•

increased insurance costs.

        The costs incurred in correcting any material defects or errors in our software may be substantial and could harm our operating results.

         If we are not successful in developing our mobile application for new devices and platforms, or if those solutions are not widely adopted, our results of operations and business could be adversely affected.

        As new mobile devices and platforms are developed, we may encounter problems in developing products for such new mobile devices and platforms, and we may need to devote significant resources to the creation, support, and maintenance of such products. In addition, if we experience difficulties integrating our mobile applications into mobile devices, or if we face increased costs to distribute our mobile applications, our future growth and our results of operations could suffer.

19

         If we fail to maintain relationships with providers of mobile operating systems or mobile application download stores, our business could be adversely affected.

        We rely on the integration of our software into mobile operating systems to allow mobile devices to connect to our network of Wi-Fi hotspots. If problems arise with our relationships with providers of mobile operating systems or mobile application download stores, such as the Apple App Store and Google Play, or if our mobile application receives unfavorable treatment compared to the promotion and placement of competing applications, such as the order of our products in the mobile application download stores, we may fail to attract or retain customers or partners, and our business could be adversely affected.

         If we fail to cost effectively develop our brand, our financial condition and operating results could be harmed.

        We market our solution under the Boingo brand. We believe that developing and maintaining awareness of our brand is important to achieving widespread acceptance of the Boingo solution, and is an important element in attracting and retaining customers and partners. Additionally, we believe that developing this brand in a cost effective manner is important in meeting our expected margins. Brand promotion activities may not result in increased revenue, and any increased revenue resulting from these promotion activities may not offset the expenses we incurred in building our brand. If we fail to cost effectively build and maintain our brand, we may fail to attract or retain customers or partners, and our financial condition and results of operations could be harmed.

Risks Related to Our Intellectual Property

         Claims by others that we infringe their proprietary technology could harm our business.

        In recent years there has been significant litigation involving intellectual property rights in many technology-based industries, including the wireless communications industry. While we have not been specifically targeted, companies similar to us have been subject to patent lawsuits. As we face increasing competition and gain an increasingly high profile, the possibility of intellectual property rights claims against us grows. We may be subject to third-party claims in the future. The costs of supporting these litigations and disputes are considerable, and there can be no assurance that a favorable outcome will be obtained. We may be required to settle these litigations and disputes on terms that are unfavorable to us, given the complex technical issues and inherent uncertainties in intellectual property litigation. Claims that the Boingo solution infringes third-party intellectual property rights, regardless of their merit or resolution, could also divert the efforts and attention of our management and technical personnel. The terms of any settlements or judgments may require us to:

•

cease distribution and back-end operation of the Boingo solution;

•

pay substantial damages for infringement;

•

expend significant resources to develop non-infringing solutions;

•

license technology from the third-party claiming infringement, which may not be available on commercially reasonable terms, or at all;

•

cross-license our technology to a competitor to resolve an infringement claim, which could weaken our ability to compete with that competitor; or

•

pay substantial damages to our partners to discontinue their use of or to replace infringing solutions sold to them with non-infringing solutions.

        Any of these unfavorable outcomes could have a material adverse effect on our business, financial condition and results of operations.

20

         If we are unable to protect our intellectual property rights, our competitive position could be harmed, or we could be required to incur significant expenses to enforce our rights.

        Our business depends on our ability to protect our proprietary technology. We rely on trade secret, patent, copyright and trademark laws and confidentiality agreements with employees and third parties, all of which offer only limited protection. We own two patents and have applications for six additional patents pending. Despite our efforts, the steps we have taken to protect our proprietary rights may not be adequate to prevent the use or misappropriation of our proprietary information or infringement of our intellectual property rights. Our ability to police the use, misappropriation or infringement of our intellectual property is uncertain, particularly in countries other than the United States. Further, we do not know whether any of our pending patent applications will result in the issuance of patents or whether the examination process will require us to narrow our claims. Even if patents are issued, they may be contested, circumvented, or invalidated in the future. Moreover, the rights granted under any issued patents may not provide us with complete proprietary protection or any competitive advantages, and, as with any technology, competitors may be able to develop similar or superior technologies on their own now or in the future. Protecting against the unauthorized use of our solutions, trademarks, and other proprietary rights is expensive, difficult and, in some cases, impossible. Litigation may be necessary in the future to enforce or defend our intellectual property rights, to protect our trade secrets, or to determine the validity and scope of the proprietary rights of others. Litigation could result in substantial costs and diversion of management resources, either of which could harm our business. Furthermore, many of our current and potential competitors have the ability to dedicate substantially greater resources to enforce their intellectual property rights than we do. Accordingly, despite our efforts, if the protection of our proprietary rights is inadequate to prevent use or misappropriation by third parties, the value of our brand and other intangible assets may be diminished and competitors may be able to more effectively mimic our service and methods of operations. Any of these events would have a material adverse effect on our business, financial condition and results of operations.

         Our use of open source software could limit our ability to commercialize the Boingo solution.

        We have incorporated open source software into the Boingo solution. Although we closely monitor our use of open source software, we are subject to the terms of open source licenses that have not been interpreted by U.S. or foreign courts, and there is a risk that in the future these licenses could be construed in a manner that imposes unanticipated conditions or restrictions on our ability to commercialize the Boingo solution. In that event, we could be required to seek licenses from third parties or to re-engineer our software in order to continue offering the Boingo solution, or to discontinue operations, any of which could materially adversely affect our business.

         We utilize unlicensed spectrum in certain of our offerings which is subject to intense competition, low barriers of entry and slowdowns due to multiple users.

        We presently utilize unlicensed spectrum to provide our Wi-Fi Internet solutions. Unlicensed or "free" spectrum is available to multiple users and may suffer bandwidth limitations, interference and slowdowns if the number of users exceeds traffic capacity. The availability of unlicensed spectrum is not unlimited and others do not need to obtain permits or licenses to utilize the same unlicensed spectrum that we currently, or may in the future, utilize. The inherent limitations of unlicensed spectrum could potentially threaten our ability to reliably deliver our services. Moreover, the prevalence of unlicensed spectrum creates low barriers to entry in our industry.

Risks Related to Ownership of Our Common Stock

         The market price of our common stock may be volatile, which could result in substantial losses for investors.

        Fluctuations in market price and volume are particularly common among securities of technology companies. As a result, you may be unable to sell your shares of common stock at or above the price you paid. The market price of our common stock may fluctuate significantly in response to the factors described in this risk factor section as well as the following factors, among others, many of which are beyond our control:

•

general market conditions;

•

domestic and international economic factors unrelated to our performance;

•

actual or anticipated fluctuations in our quarterly operating results;

•

changes in or failure to meet publicly disclosed expectations as to our future financial performance;

•

changes in securities analysts' estimates of our financial performance or lack of research and reports by industry analysts;

•

changes in market valuations or earnings of similar companies;

•

announcements by us or our competitors of significant products, contracts, acquisitions, or strategic partnerships;

•

developments or disputes concerning patents or proprietary rights, including increases or decreases in litigation expenses associated with intellectual property lawsuits we may initiate, or in which we may be named as defendants;

•

failure to complete significant sales;

•

any future sales of our common stock or other securities; and

•

additions or departures of key personnel.

         If securities or industry analysts publish misleading or unfavorable research about our business, our stock price and trading volume could decline.

        The trading market for our common stock depends in part on the research and reports that securities or industry analysts publish about us or our business. If one or more of these analysts downgrades our stock or publishes misleading or unfavorable research about our business, our stock price would likely decline. If one or more of these analysts ceases coverage of our company or fails to publish reports on us regularly, demand for our stock could decrease, which could cause our stock price or trading volume to decline. Announcements by analysts that may have a significant impact on the market price of our common stock may relate to:

•

our operating results or forecasts;

•

new issuances of equity, debt or convertible debt by us;

•

developments in our relationships with corporate customers;

•

announcements by our customers or competitors;

•

changes in regulatory policy or interpretation;

•

governmental investigations;

22

•

changes in the ratings of our stock by rating agencies or securities analysts;

•

our acquisitions of complementary businesses; or

•

our operational performance.

         Insiders have substantial control over us and are able to influence corporate matters.

        Our directors and executive officers and their affiliates are able to exercise significant influence over all matters requiring stockholder approval, including the election of directors and approval of significant corporate transactions, such as a merger or other sale of our company or its assets. This concentration of ownership could limit your ability to influence corporate matters and may have the effect of delaying or preventing a third party from acquiring control over us.

         As a public company, we are subject to financial and other reporting and corporate governance requirements that may be difficult for us to satisfy, and may divert resources and management attention from operating our business.

        We are required to file annual, quarterly and other reports with the SEC. We must prepare and timely file financial statements that comply with SEC reporting requirements. We are also subject to other reporting and corporate governance requirements, under the listing standards of the NASDAQ Stock Market, or NASDAQ, which imposes significant compliance obligations upon us. We are required, among other things, to:

•

prepare and file periodic reports, and distribute other stockholder communications, in compliance with the federal securities laws and NASDAQ rules; and

•

evaluate and maintain our system of internal control over financial reporting, and report on management's assessment thereof, in compliance with rules and regulations of the SEC and the Public Company Accounting Oversight Board. Further, we are required to obtain an opinion on the effectiveness of our internal control over financial reporting as of December 31st each year from our independent registered public accounting firm.

         If we need additional capital in the future, it may not be available on favorable terms, or at all.

        We have historically relied on outside financing and cash flow from operations to fund our operations, capital expenditures and expansion. However, we may require additional capital from equity or debt financing in the future to fund our operations, or respond to competitive pressures or strategic opportunities. We may not be able to secure timely additional financing on favorable terms, or at all. The terms of additional financing may place limits on our financial and operating flexibility. If we raise additional funds through further issuances of equity, convertible debt securities or other securities convertible into equity, our existing stockholders could suffer significant dilution in their percentage ownership of our company, and any new securities we issue could have rights, preferences and privileges senior to those of holders of our common stock. If we are unable to obtain adequate financing or financing on terms satisfactory to us, if and when we require it, our ability to grow or support our business and to respond to business challenges could be significantly limited.

         We could be the subject of securities class action litigation due to future stock price volatility, which could divert management's attention and adversely affect our results of operations.

        The stock market in general and market prices for the securities of technology companies like ours in particular, have from time to time experienced volatility that often has been unrelated to the operating performance of the underlying companies. A certain degree of stock price volatility can be attributed to being a newly public company. These broad market and industry fluctuations may adversely affect the market price of our common stock, regardless of our operating performance. In

23

several recent situations where the market price of a stock has been volatile, holders of that stock have instituted securities class action litigation against the company that issued the stock. If any of our stockholders were to bring a lawsuit against us, the defense and disposition of the lawsuit could be costly and divert the time and attention of our management and harm our operating results.

         Anti-takeover provisions in our charter documents and Delaware law could discourage, delay, or prevent a change in control of our company and may affect the trading price of our common stock.

        We are a Delaware corporation and the anti-takeover provisions of the Delaware General Corporation Law may discourage, delay, or prevent a change in control by prohibiting us from engaging in a business combination with an interested stockholder for a period of three years after the person becomes an interested stockholder, even if a change of control would be beneficial to our existing stockholders. In addition, our amended and restated certificate of incorporation and amended and restated bylaws may discourage, delay, or prevent a change in our management or control over us that stockholders may consider favorable. For example, our amended and restated certificate of incorporation and amended and restated bylaws:

•

authorize the issuance of "blank check" preferred stock that could be issued by our board of directors to thwart a takeover attempt;

•

establish a classified board of directors, as a result of which the successors to the directors whose terms have expired will be elected to serve from the time of election and qualification until the third annual meeting following their election;

•

require that directors only be removed from office for cause and only upon a majority stockholder vote;

•

provide that vacancies on the board of directors, including newly-created directorships, may be filled only by a majority vote of directors then in office;

•

limit who may call special meetings of stockholders;

•

prohibit stockholder action by written consent, thereby requiring all actions to be taken at a meeting of the stockholders; and

•

require supermajority stockholder voting to effect certain amendments to our amended and restated certificate of incorporation and amended and restated bylaws.

         We have incurred substantial losses in past and current years and may incur additional losses in the future.

        As of December 31, 2013, our accumulated deficit was $43.2 million. We generated a net loss in 2013 and we are also currently investing in our future growth through expanding our network and buildouts, investing in our software, and consideration of future business acquisitions. As a result, we will incur higher depreciation and other operating expenses, as well as potential acquisition costs, that may negatively impact our ability to achieve profitability in future periods unless and until these growth efforts generate enough revenue to exceed their operating costs and cover our additional overhead needed to scale our business for this anticipated growth. The current global financial condition may also impact our ability to achieve profitability if we cannot generate sufficient revenue to offset the increased costs. In addition, costs associated with the acquisition and integration of any acquired companies may also negatively impact our ability to achieve profitability. Finally, given the competitive and evolving nature of the industry in which we operate, we may not be able to achieve or increase profitability.

24

         We do not intend to pay dividends on our common stock and, consequently, your ability to achieve a return on your investment will depend on appreciation in the price of our common stock.

        We do not intend to declare and pay dividends on our capital stock for the foreseeable future. We currently intend to invest our future earnings, if any, to fund our growth. Therefore, you are not likely to receive any dividends on your common stock for the foreseeable future and the success of an investment in shares of our common stock will depend upon any future appreciation in their value.

         Certain of our stockholders may have claims as a result of an unauthorized e-mail sent by an employee of one of the underwriters in our IPO that may have constituted a prospectus that does not meet the requirements of the Securities Act of 1933.

        Prior to the effectiveness of the registration statement on Form S-1, an employee of Deutsche Bank Securities Inc., one of the underwriters in our initial public offering, or IPO, distributed an unauthorized e-mail message containing evaluation material and projections to approximately 200 potential institutional investors. The unauthorized e-mail message did not contain the required legends and a link to our prospectus in order to make the email a conforming underwriter free writing prospectus. Deutsche Bank Securities Inc. has informed us that all of the recipients of the e-mail have been notified that it was distributed in error and should be disregarded. Subsequently, Deutsche Bank Securities Inc. re-sent the information contained in the e-mail to the same distribution list with the required legends and links to our prospectus and our free writing prospectus in order to make the e-mail a conforming underwriter free writing prospectus.

        Neither we nor any of the other underwriters in our IPO were involved in any way in the preparation or distribution of the information contained in the e-mail, and the information does not reflect our views, or the views of the other underwriters, as to matters addressed in the e-mails. No person who received the e-mails should rely upon them in any manner. We urge all potential investors to base their investment decisions solely on our prospectus. If the e-mails did constitute a violation of the Securities Act of 1933, the recipients who purchased our common stock in the IPO may have claims for damages resulting from their purchase. Any liability would depend upon the number of shares purchased by recipients of the e-mail. If any liability is asserted, we intend to contest the matter. In addition, Deutsche Bank Securities Inc. has agreed to indemnify us, the selling stockholders and the other underwriters in the IPO for losses that we or they may incur as a result of the e-mails, and therefore, we do not believe the distribution of the e-mails will have a material financial impact on us.

Item 1B.    Unresolved Staff Comments

        None.

Item 2.    Properties

        As of December 31, 2013, we leased approximately 27,000 square feet of space for our corporate headquarters in Los Angeles, California under a lease agreement that expires in February 2018. We also leased an additional approximately 17,000 square feet in aggregate office space in San Diego, California; San Francisco, California; Chicago, Illinois; Lake Success, New York; McKinney, Texas; Detroit, Michigan; Seattle, Washington; and Sao Paolo, Brazil. We are currently evaluating the adequacy of our current office facilities.

Item 3.    Legal Proceedings

        From time to time, we may be involved in or subject to claims, suits, investigations and proceedings arising out of the normal course of business. We are not currently a party to any litigation that we believe could have a material adverse effect on our business, financial position, results of operations or cash flows.

Item 4.    Mine Safety Disclosures

        Not applicable.

Dividends

        We have never declared or paid cash dividends on our common stock, and currently do not anticipate paying cash dividends in the foreseeable future. Any future determination to pay dividends on our common stock, if permissible, will be at the discretion of our board of directors and will depend upon, among other factors, our financial condition, operating results, current and anticipated cash needs, plans for expansion and other factors that our board of directors may deem relevant.

Recent Sales of Unregistered Securities; Use of Proceeds from Sale of Registered Securities

        We did not sell any equity securities not registered under the Securities Act during the year ended December 31, 2013.

        On May 3, 2011, our registration statement on Form S-1 was declared effective by the SEC for our IPO, pursuant to which we sold 3,846,800 shares of our common stock at a public offering price of $13.50 per share. We received net proceeds of approximately $45.7 million from this transaction, after underwriting discounts, commissions and expenses. There has been no material change in the planned use of proceeds from our IPO as described in our final prospectus filed with the SEC pursuant to Rule 424(b).

Issuer Purchases of Equity Securities

        On April 1, 2013, the Company approved a stock repurchase program to repurchase up to $10,000,000 of the Company's common stock in the open market, exclusive of any commissions,

26

markups or expenses. The stock repurchased will be retired and will resume the status of authorized but unissued shares of common stock. During the quarter ended December 31, 2013, we repurchased and retired approximately 360,000 shares under this program for approximately $2,278,000, excluding commissions paid, at an average price per share of $6.33. As of December 31, 2013, the remaining approved amount for repurchases was approximately $5,180,000. Activity under the program for the quarter ended December 31, 2013 was as follows:

	Total Number of Shares Purchased(1) (000's)		Average Price Paid Per Share		Approximate Dollar Value of Shares that May Yet Be Purchased (000's)
October 1—October 31		—	$	—		7,459
November 1—November 30		150	$	6.22		6,525
December 1—December 31		210	$	6.41		5,180
Total		360

All shares purchased were purchased as part of a publicly announced program discussed above, in open-market transactions.

Performance Measurement Comparison

        The following performance graph shows the total stockholder return of an investment of $100 in cash made on May 4, 2011 in each of (i) our common stock, (ii) a broad equity market index, the securities comprising the Nasdaq Composite Index, and (iii) issuers with similar market capitalizations, the securities comprising the Russell 2000 index.

        The performance graph assumes that $100 was invested on May 4, 2011 in our common stock at the closing price of $12.10 and in each index, and that all dividends were reinvested. No dividends have been declared nor paid on our common stock. The comparisons in the graph below are required by the SEC and are not intended to forecast or be indicative of possible future performance of our common stock.

ITEM 6.    SELECTED FINANCIAL DATA

        The following selected consolidated financial data should be read in conjunction with "Management's Discussion and Analysis of Financial Condition and Results of Operations" in Part II, Item 7 and our accompanying Consolidated Financial Statements in Part II, Item 8 of this report.

        The consolidated statements of operations data set forth below for years 2013 , 2012 and 2011 and the consolidated balance sheets data as of the end of years 2013 and 2012 are derived from, and qualified by reference to, the audited consolidated financial statements included in Item 8 of this report. The consolidated statements of operations data for years 2010 and 2009 and the consolidated balance sheets data as of the end of years 2011, 2010 and 2009 are derived from the audited financial statements previously filed with the SEC on Form 10-K. The results of businesses acquired in a business combination are included in the Company's consolidated financial statements from the date of the acquisition. Refer to Note 3 in our accompanying Consolidated Financial Statements in Part II, Item 8 of this report for a discussion of the Company's business combinations for years 2013 and 2012. There were no business combinations for years 2011, 2010 and 2009.

        The consolidated statement of operations for the year 2013 includes certain out-of-period adjustments that decreased net loss attributable to common stockholders by $217,000. The 2012, 2011, 2010 and 2009 working capital balances have been revised to properly classify $2,066,000, $2,066,000, $2,236,000 and $710,000, respectively, of unbilled receivables from other non-current assets to accounts receivable, net. The impact of these out-of-period adjustments and revisions are not considered material, individually and in the aggregate, to any of the current or prior annual periods.

We define Adjusted EBITDA as net (loss) income attributable to common stockholders plus depreciation and amortization of property and equipment, accretion of convertible preferred stock, income tax expense (benefit), amortization of intangible assets, stock-based compensation expense, non-controlling interests and interest and other (income) expense, net.

We believe that Adjusted EBITDA is useful to investors and other users of our financial statements in evaluating our operating performance because it provides them with an additional tool to compare business performance across companies and across periods. We believe that:

•

Adjusted EBITDA provides investors and other users of our financial information consistency and comparability with our past financial performance, facilitates period-to-period comparisons of operations and facilitates comparisons with other companies, many of which use similar non-generally accepted accounting principles in the United States ("GAAP") financial measures to supplement their GAAP results; and

•

it is useful to exclude non-cash charges, such as accretion of preferred stock, depreciation and amortization of property and equipment, amortization of intangible assets and stock-based compensation, from Adjusted EBITDA because the amount of such expenses in any specific period may not directly correlate to the underlying performance of our business operations, and these expenses can vary significantly between periods as a result of full amortization of previously acquired tangible and intangible assets or the timing of new stock-based awards.

We use Adjusted EBITDA in conjunction with traditional GAAP measures as part of our overall assessment of our performance, for planning purposes, including the preparation of our annual operating budget and quarterly forecasts, to evaluate the effectiveness of our business strategies and to communicate with our board of directors concerning our financial performance.

30

We do not place undue reliance on Adjusted EBITDA as our only measure of operating performance. Adjusted EBITDA should not be considered as a substitute for other measures of financial performance reported in accordance with GAAP. There are limitations to using non-GAAP financial measures, including that other companies may calculate these measures differently than we do.

We compensate for the inherent limitations associated with using Adjusted EBITDA through disclosure of these limitations, presentation of our financial statements in accordance with GAAP and reconciliation of Adjusted EBITDA to the most directly comparable GAAP measure, net (loss) income attributable to common stockholders.

        The following provides a reconciliation of net (loss) income attributable to common stockholders to Adjusted EBITDA:

ITEM 7.    MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATION

The following discussion and analysis of our financial condition and results of operations should be read together with "Selected Consolidated Financial Data" and our audited consolidated financial statements and accompanying notes included elsewhere in this filing. This discussion contains forward-looking statements, based on current expectations and related to our plans, estimates, beliefs and anticipated future financial performance. These statements involve risks and uncertainties and our actual results may differ materially from those anticipated in these forward-looking statements as a result of many factors, including those set forth under "Risk Factors," "Forward-Looking Statements" and elsewhere in this filing.

Overview

        We believe we are the leading global provider of commercial mobile Wi-Fi Internet solutions. Our software applications and solutions enable individuals to access our extensive global Wi-Fi network of over 800,000 hotspots with devices such as smartphones, tablet computers, and laptops. Our offerings provide compelling cost and performance advantages to our customers and partners.

        We grew revenue from $102.5 million in 2012 to $106.7 million in 2013, an increase of 4.1%. We grew revenue from $94.6 million in 2011 to $102.5 million in 2012, an increase of 8.4%. We generated a net loss attributable to common stockholders of $3.8 million in 2013 compared to net income attributable to common stockholders of $7.3 million in 2012. Adjusted EBITDA decreased from $30.6 million in 2012 to $23.8 million in 2013, a decrease of 22.3%. For a discussion of Adjusted EBITDA and a reconciliation of net (loss) income attributable to common stockholders to Adjusted EBITDA, see footnote 1 to "Selected Financial Data" in Part II, Item 6.

        The proliferation of smartphones, tablet computers, laptops and other Wi-Fi enabled devices—in conjunction with the increased mobile consumption of streaming media, social networking, downloading large email attachments and video calling—has created a demand for high-speed, high-bandwidth Internet access in public places both large and small. These data intensive activities are driving a global surge in mobile Internet data traffic that is expected to increase 11 times between 2013 and 2018, according to Cisco's Visual Networking Index. We believe these trends present us with opportunities to generate significant growth in revenue and profitability.

Critical Accounting Policies and Estimates

        The preparation of financial statements in conformity with GAAP and rules and regulations of the United States Securities and Exchange Commission ("SEC") requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, as well as the disclosure of contingent assets and liabilities, at the date of the financial statements. Such estimates and assumptions also affect the reported amounts of revenues and expenses during the reporting period. Although we believe these estimates are reasonable, actual results could differ from these estimates. On a regular basis, we evaluate our assumptions, judgments and estimates. We also discuss our critical accounting policies and estimates with the Audit Committee of the Board of Directors.

        We believe that the assumptions and estimates associated with revenue recognition, business combinations, goodwill, measuring recoverability of long-lived assets, stock-based compensation and income taxes have the greatest potential impact on our consolidated financial statements. Therefore, we believe the accounting policies discussed below are paramount to understanding our historical and future performance, as these policies relate to the more significant areas involving our management's judgments, assumptions and estimates.

32

Revenue Recognition

        We generate revenue from several sources including: (i) platform service arrangements with wholesale customers that provide software licensing, network access, and professional services fees, (ii) wholesale customers that are telecom operators under long-term contracts for access to our DAS at our managed and operated locations, (iii) retail customers under subscription plans for month-to-month network access that automatically renew, and retail single-use access from sales of hourly, daily or other single-use access plans, and (iv) display advertisements and sponsorships on our walled garden sign-in pages. Software licensed by our wholesale platform services customers can only be used during the term of the service arrangements and has no utility to them upon termination of the service arrangement.

        We recognize revenue when an arrangement exists, services have been rendered, fees are fixed or determinable, no significant obligations remain related to the earned fees and collection of the related receivable is reasonably assured.

        Services provided to wholesale partners under platform service arrangements generally contain several elements including: (i) a term license to use our software to access our Wi-Fi network, (ii) access fees for network usage, and (iii) professional services for software integration and customization and to maintain the Wi-Fi service. The term license, monthly minimum network access fees and professional services are billed on a monthly basis based upon predetermined fixed rates. Once the term license for integration and customization are delivered, the fees from the arrangement are recognized ratably over the remaining term of the platform service arrangement. The initial term of platform service license agreements is generally between one to five years and the agreements generally contain renewal clauses. Revenue for network access fees in excess of the monthly minimum amounts is recognized when earned. All elements within existing platform service arrangements are generally delivered and earned concurrently throughout the term of the respective service arrangement.

        Revenue generated from access to our DAS networks consists of build-out fees and recurring access fees under certain long-term contracts with telecom operators. Build-out fees paid upfront are generally deferred and recognized ratably over the term of the estimated customer relationship period, once the build-out is complete. Minimum monthly access fees for usage of the DAS networks are non-cancellable and generally escalate on an annual basis. These minimum monthly access fees are recognized ratably over the term of the telecom operator agreement. The initial term of our contracts with telecom operators and wholesale partners generally range from three to fifteen years and the agreements generally contain renewal clauses. Revenue from network access fees in excess of the monthly minimums is recognized when earned.

        In instances where the minimum monthly network access fees escalate over the term of the wholesale service arrangement, an unbilled receivable is recognized when performance is within our control and when we have reasonable assurance that the unbilled receivable balance will be collected.

        For multiple-deliverable arrangements entered into prior to January 1, 2011 that are accounted for under Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 605-25, Revenue Recognition—Multiple- Deliverable Revenue Arrangements, we defer recognition of revenue for the full arrangement and recognize all revenue ratably over the wholesale service period for platform service arrangements and the term of the estimated customer relationship period for DAS arrangements, as we did not have evidence of fair value for the undelivered elements in the arrangement. For multiple-deliverable arrangements entered into or materially modified after January 1, 2011 that are accounted for under ASC 605-25, we evaluate whether or not separate units of accounting exist and then allocate the arrangement consideration to all units of accounting based on the relative selling price method using estimated selling prices if vendor specific objective evidence and third-party evidence is not available. We recognize the revenue associated with the separate units of accounting upon completion of such services or ratably over the wholesale service period for platform

33

service arrangements and the term of the estimated customer relationship period for DAS arrangements.

        Subscription fees from retail customers are paid monthly in advance and revenue is deferred for the portions of monthly recurring subscription fees collected in advance. We do not have a stated or published refund policy for our Wi-Fi service, although our customer service representatives will provide a refund on a case-by-case basis. These amounts are not significant and are recorded as contra-revenue in the period the refunds are made. Subscription fee revenue is recognized ratably over the subscription period. Revenue generated from retail single-use access is recognized when earned.

        Advertising revenue is generated from advertisements on our managed and operated or partner networks. In determining whether an arrangement exists, we ensure that a binding arrangement is in place, such as a standard insertion order or a fully executed customer-specific agreement. Obligations pursuant to our advertising revenue arrangements typically include a minimum number of units or the satisfaction of certain performance criteria. Advertising and other revenue is recognized when the services are performed.

Business Combinations

        We allocate the total purchase price of a business combination to the assets acquired and the liabilities assumed based on their estimated fair values at the acquisition date, with the excess purchase price recorded as goodwill. An income, market or cost valuation method may be utilized to estimate the fair value of the assets acquired or liabilities assumed in a business combination. The income valuation method represents the present value of future cash flows over the life of the asset using (i) discrete financial forecasts, which rely on management's estimates of revenue and operating expenses, (ii) long-term growth rates, (iii) an appropriate discount rate and (iv) an appropriate royalty rate, where applicable. The market valuation method uses prices paid for a reasonably similar asset by other purchasers in the market, with adjustments relating to any differences between the assets. The cost valuation method is based on the replacement cost of a comparable asset at prices at the time of the acquisition reduced for depreciation of the asset.

Goodwill

        Goodwill represents the excess of purchase price over fair value of net assets acquired. Goodwill is not amortized but instead is tested annually for impairment, or more frequently when events or changes in circumstances indicate that fair value of the reporting unit has been reduced to less than its carrying value. We perform our impairment test annually as of December 31^st. Entities have the option to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test described in ASC 350, Intangibles—Goodwill and Other. If, after assessing qualitative factors, an entity determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then performing the two-step impairment test is unnecessary. If deemed necessary, a two-step test is used to identify the potential impairment and to measure the amount of goodwill impairment, if any. The first step is to compare the fair value of the reporting unit with its carrying amount, including goodwill. If the fair value of the reporting unit exceeds its carrying amount, goodwill is considered not impaired; otherwise, there is an indication that goodwill may be impaired and the amount of the loss, if any, is measured by performing step two. Under step two, the impairment loss, if any, is measured by comparing the implied fair value of the reporting unit goodwill with the carrying amount of goodwill.

        At December 31, 2013 and 2012, we tested our goodwill for impairment using a market based approach and no impairment was identified as the fair value of our sole reporting unit was substantially in excess of its carrying amount. To date, we have not recorded any goodwill impairment charges.

34

Measuring Recoverability of Long-Lived Assets

        We perform an impairment review of long-lived assets held and used whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Factors we consider important that could trigger an impairment review include, but are not limited to, significant under-performance relative to projected future operating results, significant changes in the manner of our use of the acquired assets or our overall business and/or product strategies and significant industry or economic trends. When we determine that the carrying value of a long-lived asset may not be recoverable based upon the existence of one or more of these indicators, we determine the recoverability by comparing the carrying amount of the asset to net future undiscounted cash flows that the asset is expected to generate or other indices of fair value. We would then recognize an impairment charge equal to the amount by which the carrying amount exceeds the fair market value of the asset.

Stock-based Compensation

        Stock-based compensation consists of stock options and restricted stock units ("RSUs"), which are granted to employees and non-employees. We recognize compensation expense equal to the grant date fair value on a straight-line basis, net of estimated and actual forfeitures, over the employee requisite service period. The grant date fair value of our stock option awards is determined using the Black-Scholes option pricing model.

        Prior to our IPO, in 2011 and 2010, we granted options to purchase shares of our common stock. Because there was no public market for our common stock prior to our IPO, determining the fair value of our common stock required making complex and subjective judgments and there was inherent uncertainty in our estimate of fair value. Prior to our IPO, our general policy was to grant employee options at exercise prices equal to the fair value of the underlying common stock at the time of grant, as determined by us and our Board of Directors. To determine the fair value of our common stock, we considered many factors, including:

•

our current and historical financial performance;

•

our expected future financial performance;

•

our financial condition at the grant date;

•

the liquidation rights and other preferences of our preferred stock;

•

input from management;

•

the lack of marketability of our common stock;

•

the anticipation or likelihood of a potential liquidity event such as a sale of the business or IPO;

•

the condition of and outlook for our industry;

•

the business risks inherent in our business;

•

the market performance of comparable publicly-traded companies; and

•

the United States and global capital market conditions.

        To determine the estimated fair value of our common stock at each grant date, we conducted a periodic in-depth valuation analysis of our common stock prepared with the assistance of an independent valuation firm and also considered the factors noted above. Our valuation analysis followed the guidance set forth by the American Institute of Certified Public Accountants, or AICPA, Technical Practice Aid, "Valuation of Privately-Held-Company Equity Securities Issued as Compensation," referred to herein as the AICPA Practice Aid. Based on the guidance of the AICPA Practice Aid, we utilized a combination of valuation methods including an income approach using an

35

analysis of expected future discounted cash flows and a market approach for similar companies with publicly-traded ownership interests (market comparable method). We then weighted these two valuations to calculate an expected business enterprise value which was applied to our capital structure to determine a value per common share.

        The expected future discounted cash flows analysis identifies a level of annual cash flows for a finite number of years and a residual value at the end of the projection period. A discount rate which reflects estimates of investor- required rates of return for similar investments is used to calculate the present value. The market comparable method uses valuation multiples of comparable companies which are applied to our operating statistics to arrive at a value. These two business enterprise values are then equally weighted to determine the total valuation.

        To estimate the value of common shares, we used a dynamic option model to value the various components of our capital structure. These components included common shares, liquidation rights and preferences of our preferred stock, warrants and options on common shares. The total value of these securities was divided by the number of fully converted shares to provide an estimated value of common shares on a marketable, controlling interest. A discount for lack of control and lack of marketability was then applied to yield the value per common share.

        For stock-based awards granted subsequent to our IPO, our board of directors determined the fair market value based on the closing price of our common stock as reported on the NASDAQ Global Market on the date of grant.

Income Taxes

        Income taxes are provided based on the liability method, which results in income tax assets and liabilities arising from temporary differences. Temporary differences are differences between the tax basis of assets and liabilities and their reported amounts in the financial statements that will result in taxable or deductible amounts in future years. The liability method requires the effect of tax rate changes on current and accumulated deferred income taxes to be reflected in the period in which the rate change was enacted. The liability method also requires that deferred tax assets be reduced by a valuation allowance unless it is more likely than not that the assets will be realized.

        We may recognize the tax benefit from uncertain tax positions only if it is at least more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position should be measured based on the largest benefit that has a greater than 50% likelihood of being realized upon settlement with the taxing authorities.

        We establish valuation allowances when necessary to reduce deferred tax assets to the amounts expected to be realized. We evaluate the need for, and the adequacy of, valuation allowances based on the expected realization of our deferred tax assets. The factors used to assess the likelihood of realization include historical earnings, our latest forecast of taxable income and available tax planning strategies that could be implemented to realize the net deferred tax assets.

        Our effective tax rates are primarily affected by changes in our valuation allowances, the amount of our taxable income or losses in the various taxing jurisdictions in which we operate, the amount of federal and state net operating losses and tax credits, the extent to which we can utilize these net operating loss carryforwards and tax credits and certain benefits related to stock option activity.

Key Business Metrics

        In addition to monitoring traditional financial measures, we also monitor our operating performance using the following key performance indicators:

	Year Ended December 31,
	2013			2012			2011
	(in thousands, except churn data)
Subscribers		310			284			257
Monthly churn		10.1	%		9.7	%		9.2	%
Connects		50,830			24,490			12,314
DAS nodes		6.3			5.6			4.6

        Subscribers.    This metric represents the number of paying retail customers who are on a month-to-month subscription plan at a given period end.

        Monthly churn.    This metric shows the number of subscribers who canceled their subscriptions in a given month, expressed as a percentage of the average subscribers in that month. The churn in a given period is the average monthly churn in that period. This measure is one indicator of the longevity of our subscribers. Some of our customers who cancel subscriptions maintain accounts for single-use access.

        Connects.    This metric shows how often individuals connect to our global Wi-Fi network in a given period. The connects include retail and wholesale customers in both customer pay locations and customer free locations where we are a paid service provider or receive sponsorship or promotion fees. We count each connect as a single connect regardless of how many times that individual accesses the network at a given venue during their 24 hour period. This measure is an indicator of paid activity throughout our network.

        DAS nodes.    This metric represents the number of active DAS nodes as of the end of the period. A DAS node is a single communications endpoint, typically an antenna, which transmits or receives radio frequency signals wirelessly. This measure is an indicator of the reach of our DAS network.

Key Components of our Results of Operations

Revenue

        Our revenue consists of wholesale revenue, retail revenue, and advertising and other revenue.

        Wholesale.    We generate revenue from wholesale partners that license our software and pay usage-based monthly network access fees to allow their customers to access our global Wi-Fi network, and telecom operator partners that pay us build-out fees and access fees for our DAS networks. Usage-based network access fees may be measured in minutes, connects, megabytes or gigabytes, and in most cases are subject to minimum volume commitments. Other wholesale partners pay us monthly fees to provide a Wi-Fi infrastructure that we install, manage and operate at their venues for their customers under a service provider arrangement.

        Retail subscription.    We generate revenue from sales to individuals of month-to-month network access subscriptions that automatically renew, primarily through charge card transactions.

        Retail single-use.    We generate revenue from sales of hourly, daily or other single-use access to individuals primarily through charge card transactions.

        Advertising and other.    We generate revenue from advertisers that seek to reach visitors to our landing pages at our managed and operated network locations with online advertising, promotional and

37

sponsored programs and at locations where we solely provide authorized access to a partner's Wi-Fi network through sponsored access and promotional programs. In addition, we receive revenue from partners in certain venues where we manage and operate the Wi-Fi network.

        For the year ended December 31, 2013, two groups of entities affiliated with Verizon Communications, Inc. and AT&T Inc. each accounted for 14% of total revenue. For the year ended December 31, 2012, those same two groups of affiliated entities accounted for 17% and 15% of total revenue, respectively. For the year ended December 31, 2011, one group of entities affiliated with Verizon Communications, Inc. accounted for 18% of total revenue. The loss of these groups and the customers could have a material adverse impact on our consolidated statements of operations.

Costs and Operating Expenses

        We classify our costs and operating expenses as network access, network operations, development and technology, selling and marketing, general and administrative, and amortization of intangible assets. Network access costs consist primarily of payments to venues and network partners in our network. Other costs and operating expenses primarily consist of personnel costs, costs for contracted labor and development, marketing, legal, accounting and consulting services, and other professional service fees. Personnel costs include salaries, bonuses, stock-based compensation and employee benefits. Facilities costs and depreciation expenses are generally allocated based on headcount. Depreciation and amortization expenses associated with specifically identifiable property and equipment are allocated to the appropriate expense categories.

        Network access.    Network access costs consist of revenue share payments to venue owners where our managed and operated hotspots are located, usage-based fees to our roaming network partners for access to their networks, depreciation of equipment related to network build-out projects in our managed and operated locations, sale of equipment, and bandwidth and other Internet connectivity expenses in our managed and operated locations.

        Network operations.    Network operations expenses consist of costs for our customer service department and for our operations staff that designs, builds, monitors and maintains the network. Also included are expenses for our customer service provider that handles customer care inquiries and expenses for network operations contractors, equipment depreciation and software and hardware maintenance fees.

        Development and technology.    Development and technology expenses consist of costs for our product development and engineering departments, developers and our information systems services staff, depreciation of our equipment and internal-use software, and software and hardware maintenance fees.

        Selling and marketing.    Selling and marketing expenses consist of costs for our business development and marketing employees and executives, travel and entertainment and marketing programs.

        General and administrative.    General and administrative expenses consist of costs for our executive, finance and accounting, legal and human resources personnel, as well as legal, accounting, tax and other professional service fees. Also included are other corporate expenses such as charge card processing fees and bad debt expense.

        Amortization of intangible assets.    Amortization of intangible assets consists primarily of acquired venue contracts, technology and non-compete agreements.

38

Interest and Other Income (Expense), Net

        Interest and other income (expense), net, primarily consist of interest income and expense.

Income Tax Expense

        In 2013, income tax expense includes $2.3 million of tax expense related to increases in our valuation allowance. $1.7 million of the increase relates to additional valuation allowances that were established as a result of our assessment that it was more likely than not that certain federal and state deferred tax assets would not be realized. We recently won some significant new contracts for the build out of residential broadband and IPTV networks for troops stationed on military bases that will require us to make investments and incur losses in advance of experiencing any direct benefit from them including generation of revenues. In 2012, as a result of our federal net operating loss carryforwards, our income taxes include only state income taxes and federal alternative minimum taxes. In 2011, income tax expense also includes $1.3 million of tax benefits associated with the release of a portion of our state valuation allowance.

Non-controlling Interests

        Non-controlling interests are comprised of minority holdings by third parties in our subsidiaries Concourse Communications Detroit, LLC ("CCG Detroit"), Chicago Concourse Development Group, LLC ("CCDG"), and Boingo Holding Participacoes Ltda. ("BHPL").

        We attributed profits and losses to the non-controlling interest in CCG Detroit under the terms of the limited liability company agreement. CCG Detroit has generated losses over the last several years which have reduced the non-controlling owners capital account to zero in 2009 resulting in an allocation to the controlling interest holder of all operating losses and deficits created by fixed distributions to the non-controlling interest holder. The fixed distributions were terminated during September 2013 concurrent with the termination of CCG Detroit's agreement with Detroit Metropolitan Wayne County Airport.

        We are required to pay a portion of allocated net profits less capital expenditures of the preceding year to the non-controlling interest holders of CCDG. The limited liability company agreement for CCDG does not have a term. CCDG can be dissolved upon the unanimous agreement of the members, upon the sale of CCDG, upon declaration of bankruptcy, or upon the termination of the license agreement between CCDG and the City of Chicago.

        We attributed profits and losses to the non-controlling interest in BHPL under the terms of the limited liability company agreement in proportion to their holdings. The limited liability company agreement with BHPL does not have a term. We, by resolution of the members, may distribute profits against retained earnings or profit reserves existing on the most recent annual balance sheet or may draw up financial statements and distribute profits in shorter periods. BHPL can be dissolved by resolution of the members and as otherwise provided for by law.

Depreciation and amortization expense

        Depreciation expense increased $3.0 million, or 18.7%, in 2013, as compared to 2012, primarily due to increased depreciation and amortization expense from our increased fixed assets for our DAS

40

projects, Wi-Fi networks, and software development in 2013. The increase in 2013 was offset by $1.3 million from a short term DAS build-out project that was completed during 2012.

        Depreciation expense increased $3.7 million, or 29.7%, in 2012, as compared to 2011, due to increases of $1.8 million from DAS build-out projects, $1.3 million from a short term DAS build-out project that was completed during 2012 and $0.6 million of depreciation expense from operations.

Stock-based compensation expense

        Stock-based compensation expense increased $1.8 million, or 64.8%, in 2013, as compared to 2012, primarily due to $1.8 million of stock-based compensation expenses for RSUs granted to our employees and directors in 2013.

        Stock-based compensation expense decreased $0.7 million, or 20.1%, in 2012, as compared to 2011, primarily due to reversal of $1.1 million in stock-based compensation expense for unvested options held by employees who left the Company in 2012.

        Wholesale.    Wholesale revenue increased $0.4 million, or 0.9%, in 2013, as compared to 2012, due to a $2.1 million increase in wholesale service provider revenues resulting from increased deployments. The increase was also due to a $1.9 million increase in new DAS build-out projects in our managed and operated locations, which includes a $2.5 million short term build-out project that included the sale of equipment and was completed during 2013. The increases were offset by a $3.5 million decrease in partner usage based fees.

        Retail subscription.    Retail subscription revenue increased $1.6 million, or 4.9%, in 2013, as compared to 2012, due to an increase in subscribers. The impact of the increase in subscribers was partially offset by a decrease in our average monthly revenue per subscriber of 4.5% from promotional offers and the growing mix of lower-priced smartphone subscriptions compared to unlimited subscriptions.

        Retail single-use.    Retail single-use revenue decreased $3.3 million, or 24.6%, in 2013, as compared to 2012. The decrease in retail single-use revenue was due primarily to the transition of certain paid managed and operated locations to a tiered or free pricing model, the loss of certain paid managed and operated locations, and an increase in new customers that opted for subscriptions. There was a 26.9% decrease in single-use connects in 2013, as compared to 2012. Retail single-use revenue includes $0.4 million of revenues related to the venues acquired from AWG in October 2013.

        Advertising and other.    Advertising and other revenue increased $5.5 million, or 79.9%, in 2013, as compared to 2012, due to a $5.3 million increase in advertising revenues from our advertising business that resulted from the assets acquired from Cloud 9 Wireless, Inc. ("Cloud 9") in August 2012 and $1.1 million of advertising revenues related to the venues acquired from AWG in October 2013. The increase was offset by a $0.9 million decrease in other revenues.

        Network access.    Network access costs increased $5.0 million, or 11.7%, in 2013, as compared to 2012. The increase is primarily attributed to a $3.5 million increase in revenue share paid to venues in our managed and operated locations, a $2.6 million increase in costs associated with the sale of equipment for build-out projects for wholesale service providers and our short term build-out projects, a $0.7 million increase in depreciation expense, and a $0.6 million increase in other cost of sales. The increases were partially offset by a $1.3 million decrease from a short term DAS build-out project that was completed in 2012, a $0.6 million decrease in bandwidth costs and a $0.6 million decrease from customer usage at partner venues.

        Network operations.    Network operations expenses increased $3.9 million, or 26.6%, in 2013, as compared to 2012, primarily due to a $1.6 million increase in personnel related expenses, inclusive of a $0.5 million increase in stock-based compensation expenses, primarily resulting from increased headcount, a $1.2 million increase in depreciation expense, a $0.2 million increase in rent and other allocated administrative expenses, a $0.2 million increase in hardware and software maintenance expenses, and a $0.6 million increase in recruiting, internet connectivity, network maintenance, consulting and travel and entertainment expenses.

        Development and technology.    Development and technology expenses increased $0.7 million, or 6.1%, in 2013, as compared to 2012, primarily due to a $0.9 million increase in depreciation expense and a $0.4 million increase in hardware and software maintenance expenses. The increases were partially offset by a $0.3 million decrease in recruiting expenses, a $0.2 million decrease in personnel related expenses, and a $0.2 million decrease in consulting expenses.

        Selling and marketing.    Selling and marketing expenses increased $4.0 million, or 38.9%, in 2013, as compared to 2012, primarily due to a $3.2 million increase in personnel related expenses, inclusive of a $0.5 million increase in stock-based compensation expenses, primarily resulting from increased headcount and incentive compensation, a $0.4 million increase in travel and entertainment expenses, and a $0.3 million increase in rent and facilities, hardware and software maintenance and depreciation expenses.

        General and administrative.    General and administrative expenses increased $2.4 million, or 18.6%, in 2013, as compared to 2012, primarily due to a $1.5 million increase in professional fees, a $0.8 million increase in personnel related expenses, inclusive of a $0.7 million increase in stock-based compensation expenses, and a $0.2 million increase in recruiting expenses. The increases were partially offset by a $0.3 million decrease in other expenses.

43

        Amortization of intangible assets.    Amortization of intangible assets expense increased $1.1 million, or 104.0%, in 2013, as compared to 2012, due to our acquisitions of Cloud 9, Endeka Group, Inc. ("Endeka"), and AWG in August 2012, February 2013, and October 2013, respectively. For future years, amortization expense is expected to be $3.7 million for 2014, $3.5 million for 2015 and 2016, $3.2 million for 2017, $2.4 million for 2018, and $7.2 million thereafter.

Interest and Other Income (Expense), Net

        Interest and other income (expense), net, decreased $0.1 million in 2013, as compared to 2012, primarily due to our lower cash and cash equivalents and marketable securities balances during 2013 as compared to 2012.

Income Tax Expense

        Income tax expense decreased $1.7 million, or 56.6%, in 2013, as compared to 2012. Our 2013 income tax expense included $1.7 million of tax expense associated with the establishment of a valuation allowance against our federal and state deferred tax assets.

        Our future effective tax rate depends on various factors, such as our level of future taxable income, tax legislation and credits and the geographic compositions of our pre-tax income. We do not expect to incur any significant income taxes until such time that we reverse our valuation allowance against our federal and state deferred tax assets upon return to sustained profitability.

Non-controlling Interests

        Non-controlling interests remained essentially unchanged in 2013, as compared to 2012.

        Wholesale.    Wholesale revenue increased $5.8 million, or 13.2%, in 2012, as compared to 2011, due to a $6.7 million increase from DAS build-out projects in our managed and operated locations offset by a decrease of $0.5 million in partner usage-based fees and a decrease of $0.4 million from DAS access and usage fees.

        Retail subscription.    Retail subscription revenue increased $3.7 million, or 12.7%, in 2012, as compared to 2011, due to a 19.8% average increase in subscribers. This increase in subscribers was

44

partially offset by a decrease in our revenue per subscriber of 6.4% from promotional offers and the growing mix of lower-priced smartphone and tablet subscriptions compared to unlimited subscriptions.

        Retail single-use.    Retail single-use revenue decreased $2.6 million, or 16.4%, in 2012, as compared to 2011, due to a 9.2% decrease in single-use connects and a 7.9% decrease in revenue per connect as more customers opted for our lower priced hourly single use access plan. The decrease in single-use connects was due primarily to the transition of certain paid managed and operated locations to a tiered or free pricing model, an increase in new customers that opted for subscriptions and increased promotional sponsorships.

        Advertising and other.    Advertising and other revenue increased $1.1 million, or 19.1%, in 2012, as compared to 2011, due primarily to an increase in our advertising revenues from our advertising business that resulted from the assets acquired from Cloud 9 in August 2012.

        Network access.    Network access costs increased $5.2 million, or 14.0%, in 2012, as compared to 2011, due primarily to increases of $4.2 million in DAS build-out projects, $1.3 million in a short term DAS build-out project, $1.3 million in revenue share paid to venues in our managed and operated locations and $0.7 million increase in the direct costs related to the sale of equipment for venue build-outs. The increases were partially offset by a decrease of $2.3 million from customer usage at partner venues.

        Network operations.    Network operations expenses decreased $1.3 million, or 8.3%, in 2012, as compared to 2011, due to decreases of $1.4 million in personnel related expenses $0.3 million in consulting expenses, $0.3 million in hardware and software maintenance expenses, and $0.3 million in other expenses. The decreases were partially offset by increases of $0.5 million in internet connectivity expenses, $0.4 million in depreciation expense and $0.1 million in break-fix expenses.

        Development and technology.    Development and technology expenses increased $1.3 million, or 14.2%, in 2012, as compared to 2011, due to increases of $0.7 million in hardware and software maintenance expenses, $0.5 million in consulting expenses, $0.3 million in recruiting expenses and $0.2 million in depreciation expense. These increases were partially offset by decreases in personnel expenses of $0.4 million inclusive of a decrease of $0.2 million in stock-based compensation expenses.

        Selling and marketing.    Selling and marketing expenses increased $2.9 million, or 38.4%, in 2012, as compared to 2011, due to increases of $1.4 million in personnel related expenses, $1.1 million in promotional expenses, $0.2 million in consulting expenses and $0.2 million in travel and entertainment expenses.

45

        General and administrative.    General and administrative expenses increased $0.7 million, or 6.2% in 2012, as compared to 2011, due to increases of $0.6 million in professional fees, $0.4 million in franchise taxes, $0.2 million in Board of Directors expenses and $0.2 million in insurance expenses. These increases were partially offset by decreases of $0.3 million in stock-based compensation expenses, $0.2 million in rent and facilities and $0.2 million in other expenses.

        Amortization of intangible assets.    Amortization of intangible assets expense decreased $0.6 million, or 33.4%, in 2012, as compared to 2011, due to certain acquired assets being fully amortized during 2011.

Interest and Other Income (Expense), Net

        Interest and other income (expense), net, increased $0.3 million, in 2012, as compared to 2011 due primarily to the increase in interest income.

Income Tax Expense

        Income tax expense decreased $1.1 million in 2012, as compared to 2011, primarily due to benefits from disqualifying dispositions of incentive stock options and from adjustments realized upon filing our 2011 federal income tax returns.

Non-controlling Interests

        Non-controlling interests remained essentially unchanged in 2012, as compared to 2011.

Liquidity and Capital Resources

        We have financed our operations primarily through cash provided by operating activities. Our primary sources of liquidity as of December 31, 2013 consisted of $27.3 million of cash and cash equivalents and $33.0 million of marketable securities.

        Our principal uses of liquidity have been to fund our operations, working capital requirements, capital expenditures and acquisitions. We expect that these requirements will be our principal needs for liquidity over the near term. Our capital expenditures in 2013 were $29.5 million, of which $16.9 million was reimbursed through revenue for DAS build-out projects from our telecom operator customers.

        We believe that our existing cash and cash equivalents, working capital and our cash flow from operations will be sufficient to fund our operations, planned capital expenditures and potential acquisitions for at least the next 12 months. There can be no assurance that future industry-specific or other developments, general economic trends, or other matters will not adversely affect our operations or our ability to meet our future cash requirements. Our future capital requirements will depend on many factors including our rate of revenue growth, the timing and size of our managed and operated location expansion efforts, the timing and extent of spending to support product development efforts, the timing of introductions of new solutions and enhancements to existing solutions and the continuing market acceptance of our solutions. We expect our capital expenditures in 2014 will range from $30 million to $40 million, excluding capital expenditures for DAS build-out projects which are reimbursed through revenue from our telecom operator customers. The majority of our 2014 capital expenditures will be used to build out residential broadband and IPTV networks for troops stationed on military bases pursuant to our contracts with the U.S. government. The investment of these resources will occur in advance of experiencing any direct benefit from them including generation of revenues. The U.S. government may modify, curtail or terminate its contracts with us, either at its convenience or for default based on performance. Any such modification, curtailment, or termination of one or more of our government contracts could have a material adverse effect on our earnings, cash flow and/or financial position. We may also enter into acquisitions of complementary businesses,

46

applications or technologies which could require us to seek additional equity or debt financing. Additional funds may not be available on terms favorable to us, or at all.

        The following table sets forth cash flow data for the periods indicated therein:

Net (decrease) increase in cash and cash equivalents	$	(30,800	)	$	(35,795	)	$	68,212

Net Cash Provided by Operating Activities

        In 2013, we generated $20.7 million of net cash from operating activities, a decrease of $3.9 million from 2012. The decrease is primarily due to an $11.0 million decrease in our net income including non-controlling interests from the prior year and a $1.9 million decrease in excess windfall tax benefits from stock option exercises. The decreases were partially offset by a $4.1 million increase in depreciation and amortization expenses in 2013, a $1.6 million decrease in prepaids and other assets in 2013 compared to a $0.3 million increase in prepaids and other assets in 2012, a $1.8 million increase in stock-based compensation expenses in 2013, and a $1.2 million smaller decrease in accrued expenses and other liabilities in 2013 compared to 2012.

        In 2012, we generated $24.6 million in cash from operating activities, a decrease of $4.9 million from 2011, which was primarily due to a $4.5 million increase in accounts receivable and other assets, a $2.2 million decrease in deferred revenues, a $1.5 million decrease in accounts payable and accrued expenses and a $1.8 million decrease in deferred taxes. These changes were offset by $1.8 million in excess tax benefits from stock-based compensation, a $2.2 million increase in non-cash charges for depreciation, amortization and stock compensation and a $1.1 million increase in net income.

        In 2011, we generated $29.5 million of net cash from operating activities, an increase of $5.4 million from 2010, which was primarily due to a $13.2 million increase in deferred taxes, a $4.1 million decrease in accounts receivable and other assets and a $6.6 million increase in non-cash charges for depreciation, amortization and stock compensation. These changes were offset by a $9.2 million decrease in net income, a $6.8 million decrease in deferred revenues and a $2.5 million decrease in accounts payable and accrued expenses.

Net Cash Used in Investing Activities

        In 2013, we used $40.4 million in investing activities, a decrease of $22.1 million from 2012. The decrease was primarily due to $8.6 million of cash received from net sales of marketable securities in 2013 compared to $41.6 million of cash used in net purchases of marketable securities in 2012. The decrease was offset by an $11.5 million increase in purchases of property and equipment in 2013 compared to 2012 and $19.5 million in net cash payments made for our acquisitions of Endeka and AWG in 2013 compared to the $3.2 million of cash payments made for our acquisition of Cloud 9 in 2012.

        In 2012, we used $62.5 million in investing activities. Our investing activities in 2012 included net purchases of $41.6 million of marketable securities, $18.0 million of purchases of property and equipment primarily related to DAS build-out projects in our managed and operated locations, net payment of $3.2 million for acquired assets and $0.1 million of payments for patents, trademarks and domain. These uses of cash were partially offset by a $0.4 million decrease in restricted cash.

47

        In 2011, we used $7.3 million in investing activities. Investing activities consisted of purchases of $16.9 million of property and equipment primarily related to DAS build-out projects in our managed and operated locations, $0.2 million of payments related to acquisitions and $0.1 million of payments for patents, trademarks and domain. These uses of cash were partially offset by $9.4 million in sales of marketable securities, and a $0.5 million decrease in restricted cash.

Net Cash Provided by Financing Activities

        In 2013, we used $11.1 million in financing activities compared to cash provided by financing activities of $2.1 million in 2012. The change was primarily due to $6.1 million of cash used to repay notes payable and other financed liabilities that were assumed in our acquisition of Endeka in 2013, the $4.8 million of cash used to repurchase and retire approximately 722,000 shares of our common stock in the open market under our stock repurchase program at an average price per share of $6.68 in 2013, and a $2.0 million decrease in proceeds from the exercise of stock options in 2013 compared to 2012.

        In 2012, we generated $2.0 million in financing activities. This was primarily due to $2.6 million in proceeds from the exercise of stock options and $0.4 million of excess tax benefits from stock-based compensation, partially offset by payments to non-controlling interests of $0.7 million and payments of capital leases of $0.2 million.

        In 2011, we generated $46.0 million in financing activities, an increase of $47.2 million from the net use of cash in the 2010. Cash provided by financing activities was primarily due to the proceeds from our IPO.

Transactions with Related Parties

        Under our Audit Committee charter, our Audit Committee is responsible for reviewing and approving all related party transactions on a quarterly basis. In addition, our Board of Directors determines annually whether any related party relationships exist among the directors which would interfere with the judgment of individual directors in carrying out his responsibilities as director.

Contractual Obligations and Commitments

        The following table sets forth our contractual obligations and commitments as of December 31, 2013:

(2)

Office space under non-cancellable operating leases.

48

(3)

Open purchase commitments are for the purchase of property and equipment, supplies and services. They are not recorded as liabilities on our consolidated balance sheet as of December 31, 2013 as we have not received the related goods or services.

(4)

Contingent consideration related to business acquisitions (refer to Note 3 to the accompanying Consolidated Financial Statements included in Part II, Item 8).

(5)

Leased equipment, primarily for data communication and database software, under non-cancellable capital leases.

Off-Balance Sheet Arrangements

        We do not have any off-balance sheet financing arrangements and we do not have any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes.

Inflation

        Inflationary factors have not had a significant effect on our performance over the past several years. A significant increase in inflation may affect our future performance since we may not be able to recover the increases in our costs with similar increases in our prices.

Item 7A.    Quantitative and Qualitative Disclosures About Market Risk

        Market risk represents the potential loss arising from adverse changes in the value of financial instruments. The risk of loss is assessed based on the likelihood of adverse changes in fair values, cash flows or future earnings.

        We have established guidelines relative to the diversification and maturities of investments to maintain safety and liquidity. These guidelines are reviewed periodically and may be modified depending on market conditions. Although investments may be subject to credit risk, our investment policy specifies credit quality standards for our investments and limits the amount of credit exposure from any single issue, issuer or type of investment. At December 31, 2013, our market risk sensitive instruments consisted of marketable securities available-for-sale, which are comprised of highly rated short-term corporate bonds.

        Marketable securities available-for-sale are carried at fair value and are intended for use in meeting our ongoing liquidity needs. Unrealized gains and losses on available-for-sale securities, which are deemed to be temporary, are reported as a separate component of stockholders' equity, net of tax. Unrealized gains and losses on available-for-sale securities have not been significant. The cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity. The amortization, along with realized gains and losses is included in interest and other income (expense), net.

Item 8.    Financial Statements and Supplementary Data

Item 9A.    Controls and Procedures

Disclosure Controls and Procedures

        The Company maintains a system of disclosure controls and procedures that are designed to provide reasonable assurance that information required to be disclosed in the reports that the Company files or submits under the Securities Exchange Act of 1934, as amended, or the Exchange Act, is processed, recorded, summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and forms. These disclosure controls and procedures include, among other processes, controls and procedures designed to ensure that information required to be disclosed in the reports that the Company files or submits under the Exchange Act is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer (our principal executive officer and principal financial officer, respectively), as appropriate, to allow for timely decisions regarding required disclosure.

        The Company carried out an evaluation, under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of December 31, 2013 pursuant to Exchange Act Rule 13a-15. Based upon that evaluation, the Company's Chief Executive Officer and Chief Financial Officer have concluded that the Company's disclosure controls and procedures, as defined in Exchange Act Rule 13a-15(e) and 15d-15(e), were effective as of the end of the period covered by this Annual Report.

Management's Report on Internal Control over Financial Reporting

        Management is responsible for establishing and maintaining adequate internal control over financial reporting at the Company. Our internal control over financial reporting is a process designed under the supervision of our Chief Executive Officer and Chief Financial Officer to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the Company's financial statements for external reporting purposes in accordance with GAAP. A company's internal control over financial reporting includes those policies and procedures that:

•

pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company;

•

provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and the directors of the company; and

•

provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company's assets that could have a material effect on the financial statements.

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

        Under the supervision and with the participation of management, including the certifying officers, the Company conducted an evaluation of the effectiveness of the Company's internal control over financial reporting as of December 31, 2013 based on the framework in Internal Control—Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Management's assessment included an evaluation of the design of the Company's internal

control over financial reporting and testing of the operational effectiveness of its internal control over financial reporting.

        Management has excluded Electronic Media Systems, Inc. and Advanced Wireless Group, LLC from its assessment of internal control over financial reporting as of December 31, 2013 because they were acquired by the Company in a purchase business combination during 2013. Electronic Media Systems, Inc. and Advanced Wireless Group, LLC are wholly-owned subsidiaries whose total assets and total revenues represent $22.7 million and $1.7 million, respectively, of the related consolidated financial statement amounts as of and for the year ended December 31, 2013.

        Based on this assessment, management determined that, as of December 31, 2013, the Company maintained effective internal control over financial reporting. The registered public accounting firm that audited the consolidated financial statements included in this Annual Report has also issued an audit report on the Company's internal control over financial reporting. The registered public accounting firm's audit of internal control over financial reporting also excluded Electronic Media Systems, Inc. and Advanced Wireless Group, LLC.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of Boingo Wireless, Inc.:

        In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of operations, convertible preferred stock and stockholders' equity (deficit) and cash flows present fairly, in all material respects, the financial position of Boingo Wireless, Inc. and its subsidiaries ("Company") at December 31, 2013 and 2012, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2013 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2013, based on criteria established in Internal Control—Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company's management is responsible for these financial statements, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in Management's Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on these financial statements and on the Company's internal control over financial reporting based on our audits (which were integrated audits in 2013 and 2012). We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

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

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

F-2

        As described in Management's Report on Internal Control over Financial Reporting appearing under Item 9A, management has excluded Electronic Media Systems, Inc. and Advanced Wireless Group, LLC from its assessment of internal control over financial reporting as of December 31, 2013 because they were acquired by the Company in a purchase business combination during 2013. We have also excluded Electronic Media Systems, Inc. and Advanced Wireless Group, LLC from our audit of internal control over financial reporting. Electronic Media Systems, Inc. and Advanced Wireless Group, LLC are wholly-owned subsidiaries whose total assets and total revenues represent $22.7 million and $1.7 million, respectively, of the related consolidated financial statement amounts as of and for the year ended December 31, 2013.

1. The business

        Boingo Wireless, Inc. and its subsidiaries (collectively "we, "us", "our" or "the Company") is a leading global provider of mobile Internet solutions for smartphones, tablet computers, laptops, and other wireless-enabled consumer devices. The Company has more than a million small cell networks for cellular distributed antenna system ("DAS") and Wi-Fi access that reach more than one billion consumers annually. Boingo Wireless, Inc. was incorporated in April 16, 2001 in the State of Delaware. We have a diverse monetization model that enables us to generate revenues from retail sales, wholesale partnerships, and advertising across these small cell networks. Retail products include Wi-Fi subscriptions and day passes that provide access to more than 800,000 commercial hotspots worldwide, and Internet Protocol television ("IPTV") services and residential broadband for military barracks. Wholesale offerings include Wi-Fi roaming, private label Wi-Fi, location based services, and DAS, which are cellular extension networks. Advertising revenue is driven by Wi-Fi sponsorships at airports, hotels, cafes and restaurants, and public spaces. Our customers include some of the world's largest carriers, telecommunications service providers and global consumer brands, as well as Internet savvy consumers on the go and troops stationed at military bases.

Initial public offering

        On May 3, 2011, our registration statement registering 3,846,800 shares of common stock offered by us and 1,923,200 shares offered by certain selling stockholders was declared effective by the United States Securities and Exchange Commission, and the shares began trading on the NASDAQ Global Market on May 4, 2011 under the symbol "WIFI." The proceeds from the sale of these shares are used primarily for working capital and other general corporate purposes. As a result of the initial public offering ("IPO"), we raised a total of approximately $45,701 in net proceeds after deducting underwriting discounts and commissions of approximately $3,635 and offering expenses of approximately $2,596. In connection with the IPO, all of the shares of our convertible preferred stock were converted into 22,845,764 shares of common stock and all of the warrants to purchase preferred stock were exercised and converted into 20,172 shares of common stock through net-share settlement.

Reverse stock split

        On April 7, 2011, our board of directors approved a 5 for 1 reverse stock split of our outstanding common stock which was effected on May 3, 2011. Fractional shares were settled in cash totaling approximately $1 for common and preferred stockholders. No fractional shares were settled for option holders, and they were rounded down as a result of the reverse stock split. Shares of common stock underlying outstanding stock options and warrants and shares of our preferred stock and warrants were proportionately reduced and the respective exercise prices were proportionately increased in accordance with the terms of the agreements governing such securities. Shares of common stock reserved for issuance upon the conversion of our convertible preferred stock were proportionately reduced and the respective conversion prices were proportionately increased. All references to shares in the accompanying consolidated financial statements and the notes thereto, including but not limited to the number of shares and per share amounts, unless otherwise noted, have been adjusted to reflect the reverse stock split retroactively. Previously awarded options and warrants to purchase shares of our common and preferred stock have also been retroactively adjusted to reflect the reverse stock split.

        Our consolidated financial statements for the years ended December 31, 2013, 2012 and 2011 have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP").

        The accompanying consolidated financial statements include our accounts and our majority owned subsidiaries. We consolidate our 70% ownership of Concourse Communications Detroit, LLC, our 70% ownership of Chicago Concourse Development Group, LLC and our 75% ownership of Boingo Holding Participacoes Ltda. in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 810, Consolidation. Other parties' interests in consolidated entities are reported as non-controlling interests. All intercompany balances and transactions have been eliminated in consolidation.

        During the year ended December 31, 2013, the Company recorded certain out-of-period adjustments that decreased net loss attributable to common stockholders by $217. The impact of these out-of-period adjustments is not considered material, individually and in the aggregate, to any of the current or prior annual periods.

        The consolidated balance sheet as of December 31, 2012 has been revised to properly classify $2,066 of unbilled receivables from other non-current assets to accounts receivable, net. The revision has also been reflected in Note 5 to the consolidated financial statements. The impact of this revision is not material to the prior year consolidated balance sheet.

Use of estimates

        The preparation of accompanying consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the dates of the accompanying consolidated financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Assets and liabilities which are subject to significant judgment and the use of estimates include the allowance for doubtful accounts, recoverability of goodwill and long-lived assets, valuation allowances with respect to deferred tax assets, uncertain tax positions, useful lives associated with property and equipment, valuation and useful lives of intangible assets, valuation of contingent consideration, and the valuation and assumptions underlying stock-based compensation and other equity instruments. On an ongoing basis, we evaluate our estimates compared to historical experience and trends, which form the basis for making judgments about the carrying value of assets and liabilities. In addition, prior to our IPO, we regularly engaged the assistance of valuation specialists in determining fair value measurements in connection with stock-based compensation and other equity instruments.

Concentrations of credit risk

        Financial instruments that potentially subject us to significant concentrations of credit risk consist primarily of cash and cash equivalents, restricted cash, marketable securities and accounts receivable. We maintain our cash and cash equivalents, restricted cash and marketable securities with institutions with high credit ratings. We extend credit based upon the evaluation of the customer's financial

condition and generally collateral is not required. We maintain an allowance for doubtful accounts based upon expected collectability of accounts receivable. We primarily estimate our allowance for doubtful accounts based on a specific review of significant outstanding accounts receivable. For the year ended December 31, 2013 two groups of affiliated entities each accounted for 14% of total revenue. For the year ended December 31, 2012, those same two groups of affiliated entities accounted for 17% and 15% of total revenue, respectively. For the year ended December 31, 2011, one group of affiliated entities accounted for 18% of total revenue. At December 31, 2013, one group of affiliated entities accounted for 12% of the total accounts receivable. At December 31, 2012, three groups of affiliated entities accounted for 26%, 16% and 10% of the total accounts receivable, respectively.

Cash and cash equivalents

        Cash and cash equivalents include highly liquid investments that are readily convertible into known amounts of cash with original maturities of three months or less when acquired. At December 31, 2013, cash equivalents consisted of money market funds. At December 31, 2012, cash equivalents consisted of money market funds and marketable securities with original maturities of three months or less.

Marketable securities

        Our marketable securities consist of available-for-sale securities with original maturities exceeding three months. In accordance with FASB ASC 320, Investments—Debt and Equity Securities, we have classified securities, which have readily determinable fair values and are highly liquid, as short-term because such securities are expected to be realized within a one- year period. At December 31, 2013 and 2012, we had $32,962 and $41,558, respectively, in short-term marketable securities and no long-term marketable securities.

        Marketable securities are reported at fair value with the related unrealized gains and losses reported as other comprehensive income (loss) until realized or until a determination is made that an other-than-temporary decline in market value has occurred. No significant unrealized gains and losses have been reported during the years presented. Factors considered by us in assessing whether an other-than-temporary impairment has occurred include the nature of the investment, whether the decline in fair value is attributable to specific adverse conditions affecting the investment, the financial condition of the investee, the severity and the duration of the impairment and whether we have the ability to hold the investment to maturity. When it is determined that an other-than-temporary impairment has occurred, the investment is written down to its market value at the end of the period in which it is determined that an other-than-temporary decline has occurred. The cost of marketable securities sold is based upon the specific identification method. Any realized gains or losses on the sale of investments are reflected as a component of interest and other income (expense), net.

        For the years ended December 31, 2013, 2012 and 2011, we had no significant realized or unrealized gains or losses from investments in marketable securities classified as available-for-sale.

Restricted cash

        Restricted cash consists of letters of credit with our landlords, municipalities or venues for which we have operating agreements. Letters of credit are supported by cash deposits made by us and

invested into bank certificates of deposit. At December 31, 2013 and 2012, we had $545 and $30 classified as short-term restricted cash, respectively. At December 31, 2013 and 2012, we had no restricted cash classified as long-term.

Fair value of financial instruments

        Fair value is defined as the price that would be received from selling an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, we consider the principal or most advantageous market in which it would transact, and we consider assumptions that market participants would use when pricing the asset or liability.

        The accounting guidance for fair value measurement also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard establishes a fair value hierarchy based on the level of independent, objective evidence surrounding the inputs used to measure fair value. A financial instrument's categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The fair value hierarchy is as follows:

•

Level 1—Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.

•

Level 2—Quoted prices for identical assets and liabilities in markets that are not active, quoted prices for similar assets and liabilities in active markets or financial instruments for which significant inputs are observable, either directly or indirectly.

•

Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

        The carrying amount reflected in the accompanying consolidated balance sheets for cash and cash equivalents, restricted cash, marketable securities, accounts receivable, prepaid expenses and other current assets, accounts payable, accrued expenses and other liabilities approximates fair value due to the short-term nature of these financial instruments.

Business combinations

        The results of businesses acquired in a business combination are included in the Company's consolidated financial statements from the date of the acquisition. Purchase accounting results in assets and liabilities of an acquired business being recorded at their estimated fair values on the acquisition date. Any excess consideration over the fair value of assets acquired and liabilities assumed is recognized as goodwill.

        The Company performs valuations of assets acquired and liabilities assumed from a business acquisition and will allocate the purchase price to its respective net tangible and intangible assets. Determining the fair value of assets acquired and liabilities assumed requires management to use significant judgment and estimates including the selection of valuation methodologies, estimates of future revenues and cash flows, discount rates, royalty rates and selection of comparable companies.

2. Summary of significant accounting policies (Continued)

The Company engages the assistance of valuation specialists in concluding on fair value measurements in connection with fair values of assets and liabilities assumed in a business combination.

        Transaction costs associated with business combinations are expensed as incurred, and are included in general and administrative expenses in the consolidated statements of operations. Transaction costs were $354 and $50 for the years ended December 31, 2013 and 2012, respectively. There were no transaction costs for the year ended December 31, 2011.

Property and equipment

        Property and equipment are generally stated at historical cost, less accumulated depreciation and amortization. The Company's cost basis includes property and equipment acquired in business combinations that were initially recorded at fair value as of the date of acquisition. Maintenance and repairs are charged to expense as incurred and the cost of additions and betterments that increase the useful lives of the assets are capitalized. Depreciation and amortization is computed over the estimated useful lives of the related asset type using the straight-line method.

        The estimated useful lives for property and equipment are as follows:

Computer equipment	2 to 5 years
Software	2 to 5 years
Office equipment	3 to 5 years
Leasehold improvements	The shorter of the estimated useful life or the remaining term of the agreements, generally ranging from 2 to 15 years

        Leasehold improvements are principally comprised of network equipment located at various managed and operated locations, primarily airports, under exclusive, long-term, non-cancelable contracts to provide wireless communication network access.

Equipment and software under capital lease

        We lease certain data communications equipment, other equipment and software under capital lease agreements. The assets and liabilities under capital lease are recorded at the lesser of the present value of aggregate future minimum lease payments, including estimated bargain purchase options, or the fair value of the asset under lease. Assets under capital lease are depreciated using the straight-line method over the shorter of the estimated useful lives of the assets or the term of the lease agreements.

Software development costs

        We capitalize costs associated with software developed or obtained for internal use when the preliminary project stage is completed and it is determined that the software will provide significantly enhanced capabilities and modifications. These capitalized costs are included in property and equipment and include external direct cost of services procured in developing or obtaining internal-use software and personnel and related expenses for employees who are directly associated with, and who devote time to internal-use software projects. Capitalization of these costs ceases once the project is substantially complete and the software is ready for its intended use. Once the software is ready for its

intended use, the costs are amortized over the useful life of the software. Post-configuration training and maintenance costs are expensed as incurred.

Long-lived assets

        Intangible assets consist of acquired venue contracts, technology, advertiser relationships, non-compete agreements and patents and trademarks. We record intangible assets at fair value as of the date of acquisition and amortize these finite-lived assets over the shorter of the contractual life or the estimated useful life on a straight-line basis. We estimate the useful lives of acquired intangible assets based on factors that include the planned use of each acquired intangible asset, the expected pattern of future cash flows to be derived from each acquired intangible asset and contractual periods specified in the related agreements. As such, we account for each of the venue contracts individually. We include amortization of acquired intangibles in amortization of intangible assets in the accompanying consolidated statements of operations.

        We perform an impairment review of long-lived assets held and used whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Factors we consider important that could trigger an impairment review include, but are not limited to: significant under-performance relative to projected future operating results, significant changes in the manner of our use of the acquired assets or our overall business and product strategies and significant industry or economic trends. When we determine that the carrying value of a long-lived asset may not be recoverable based upon the existence of one or more of these indicators, we determine the recoverability by comparing the carrying amount of the asset to net future undiscounted cash flows that the asset is expected to generate or other indices of fair value. We would then recognize an impairment charge equal to the amount by which the carrying amount exceeds the fair market value of the asset.

Goodwill

        Goodwill represents the excess of the purchase price over the fair value of net assets acquired in connection with the acquisition of Concourse Communication Group, LLC in June 2006, Cloud 9 Wireless, Inc. in August 2012, Endeka Group, Inc. in February 2013, and Electronic Media Systems, Inc. and Advanced Wireless Group, LLC in October 2013.

        We test goodwill for impairment in accordance with guidance provided by FASB ASC 350, Intangibles—Goodwill and Other ("ASC 350"). Goodwill is tested for impairment at least annually at the reporting unit level or whenever events or changes in circumstances indicate that goodwill might be impaired. Events or changes in circumstances which could trigger an impairment review include a significant adverse change in legal factors or in the business climate, an adverse action or assessment by a regulator, unanticipated competition, a loss of key personnel, significant changes in the manner of our use of the acquired assets or the strategy for our overall business, significant negative industry or economic trends, or significant underperformance relative to expected historical or projected future results of operations. We perform our impairment test annually as of December 31^st.

        Entities have the option to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test described in

F-13

2. Summary of significant accounting policies (Continued)

FASB ASC 350. If, after assessing qualitative factors, an entity determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then performing the two-step impairment test is unnecessary. If deemed necessary, a two-step test is used to identify the potential impairment and to measure the amount of goodwill impairment, if any. The first step is to compare the fair value of the reporting unit with its carrying amount, including goodwill. If the fair value of the reporting unit exceeds its carrying amount, goodwill is considered not impaired; otherwise, there is an indication that goodwill may be impaired and the amount of the loss, if any, is measured by performing step two. Under step two, the impairment loss, if any, is measured by comparing the implied fair value of the reporting unit goodwill with the carrying amount of goodwill.

        Currently, we have one reporting unit, one operating segment and one reportable segment. At December 31, 2013 and 2012, all of the goodwill was attributed to our reporting unit. We tested our goodwill for impairment using a market based approach and no impairment was identified as the fair value of our reporting unit was substantially in excess of its carrying amount. To date, we have not recorded any goodwill impairment charges.

Revenue recognition

        We generate revenue from several sources including: (i) platform service arrangements with wholesale customers that provide software licensing, network access, and professional services fees, (ii) wholesale customers that are telecom operators under long-term contracts for access to our DAS at our managed and operated locations, (iii) retail customers under subscription plans for month-to-month network access that automatically renew, and retail single-use access from sales of hourly, daily or other single-use access plans, and (iv) display advertisements and sponsorships on our walled garden sign-in pages. Software licensed by our wholesale platform services customers can only be used during the term of the service arrangements and has no utility to them upon termination of the service arrangement.

        We recognize revenue when an arrangement exists, services have been rendered, fees are fixed or determinable, no significant obligations remain related to the earned fees and collection of the related receivable is reasonably assured.

        Services provided to wholesale partners under platform service arrangements generally contain several elements including: (i) a term license to use our software to access our Wi-Fi network, (ii) access fees for network usage, and (iii) professional services for software integration and customization and to maintain the Wi-Fi service. The term license, monthly minimum network access fees and professional services are billed on a monthly basis based upon predetermined fixed rates. Once the term license for integration and customization are delivered, the fees from the arrangement are recognized ratably over the remaining term of the platform service arrangement. The initial term of platform service license agreements is generally between one to five years and the agreements generally contain renewal clauses. Revenue for network access fees in excess of the monthly minimum amounts is recognized when earned. All elements within existing platform service arrangements are generally delivered and earned concurrently throughout the term of the respective service arrangement.

        Revenue generated from access to our DAS networks consists of build-out fees and recurring access fees under certain long-term contracts with telecom operators. Build-out fees paid upfront are generally deferred and recognized ratably over the term of the estimated customer relationship period,

F-14

Notes to the Consolidated Financial Statements (Continued)

(In thousands, except shares and per share amounts)

2. Summary of significant accounting policies (Continued)

once the build-out is complete. Minimum monthly access fees for usage of the DAS networks are non-cancellable and generally escalate on an annual basis. These minimum monthly access fees are recognized ratably over the term of the telecom operator agreement. The initial term of our contracts with telecom operators and wholesale partners generally range from three to fifteen years and the agreements generally contain renewal clauses. Revenue from network access fees in excess of the monthly minimums is recognized when earned.

        In instances where the minimum monthly network access fees escalate over the term of the wholesale service arrangement, an unbilled receivable is recognized when performance is within our control and when we have reasonable assurance that the unbilled receivable balance will be collected.

        We adopted the provisions of Accounting Standards Update ("ASU") 2009-13, Revenue Recognition (Topic 605)—Multiple-Deliverable Revenue Arrangements ("ASU 2009-13"), on a prospective basis on January 1, 2011. For multiple-deliverable arrangements entered into prior to January 1, 2011 that are accounted for under ASC 605-25, Revenue Recognition—Multiple-Deliverable Revenue Arrangements, we defer recognition of revenue for the full arrangement and recognize all revenue ratably over the wholesale service period for platform service arrangements and the term of the estimated customer relationship period for DAS arrangements, as we do not have evidence of fair value for the undelivered elements in the arrangement. For multiple-deliverable arrangements entered into or materially modified after January 1, 2011 that are accounted for under ASC 605-25, we evaluate whether or not separate units of accounting exist and then allocate the arrangement consideration to all units of accounting based on the relative selling price method using estimated selling prices if vendor specific objective evidence and third party evidence is not available. We recognize the revenue associated with the separate units of accounting upon completion of such services or ratably over the wholesale service period for platform service arrangements and the term of the estimated customer relationship period for DAS arrangements.

        Subscription fees from retail customers are paid monthly in advance and revenue is deferred for the portions of monthly recurring subscription fees collected in advance. We do not have a stated or published refund policy for our Wi-Fi service, although our customer service representatives will provide a refund on a case-by-case basis. These amounts are not significant and are recorded as contra-revenue in the period the refunds are made. Subscription fee revenue is recognized ratably over the subscription period. Revenue generated from retail single-use access is recognized when earned.

        Advertising revenue is generated from advertisements on our managed and operated or partner networks. In determining whether an arrangement exists, we ensure that a binding arrangement is in place, such as a standard insertion order or a fully executed customer-specific agreement. Obligations pursuant to our advertising revenue arrangements typically include a minimum number of units or the satisfaction of certain performance criteria. Advertising and other revenue is recognized when the services are performed.

Network access

        Network access costs consist primarily of revenue share payments to venue owners where our managed and operated hotspots are located, usage-based fees to our roaming network partners for access to their networks, depreciation of equipment related to network build-out projects in our

managed and operated locations, and bandwidth and other Internet connectivity expenses in our managed and operated locations.

Advertising, marketing and promotion costs

        Advertising production costs are expensed the first time the advertisement is run. No advertising production costs were capitalized for the years ended December 31, 2013, 2012 and 2011. All other costs of advertising, marketing and promotion are expensed as incurred. Advertising expenses charged to operations totaled $2,302, $2,374 and $1,393 for the years ended December 31, 2013, 2012 and 2011, respectively.

Stock-based compensation

        Our stock-based compensation consists of stock options and restricted stock units ("RSU") granted to employees and non-employees.

        We recognize stock-based compensation expense in accordance with guidance provided by FASB ASC 718, Compensation—Stock Compensation ("ASC 718"). We measure employee stock-based compensation cost at grant date, based on the estimated fair value of the award and recognize the cost on a straight-line basis, net of estimated forfeitures, over the employee requisite service period. We estimate the fair value of stock options using a Black-Scholes option pricing model. The model requires input of assumptions regarding expected term, expected volatility, dividend yield, and a risk-free interest rate. The weighted average assumptions that were used to calculate the grant date fair value of our employee stock option grants for the following periods are as follows:

	December 31,
	2013			2012			2011
Expected term (years)		6.25			5.9			6.4
Expected volatility		49.31	%		48.9	%		49.8	%
Risk-free interest rate		1.34	%		0.9	%		2.4	%
Dividend yield		0	%		0	%		0	%

        The expected term of employee stock options represents the weighted-average period that the stock options are expected to remain outstanding. In estimating the expected term for options granted to employees, we applied the simplified method from the Security Exchange Commission ("SEC") Staff Accounting Bulletin ("SAB") Topic 14, Share-Based Payment ("SAB Topic 14"), where options are granted at-the-money. Where options were not granted at-the-money, the expected term of employee stock options represents the weighted-average period that the stock options are expected to remain outstanding and is calculated based upon actual historical exercise and post-vesting cancellations, adjusted for expected future exercise behavior.

2. Summary of significant accounting policies (Continued)

        We determine the fair value of common stock underlying the stock option awards by reference to third party sales of our common stock. Prior to our IPO, the fair value of common stock underlying the stock option awards was determined with the assistance of a third-party valuation specialist.

        We determined the expected volatility assumption using the frequency of daily historical prices of comparable public companies' common stock for a period equal to the expected term of the options in accordance with guidance in ASC 718 and SAB Topic 14. We will continue to monitor peer companies and other relevant factors, including our volatility after there is enough history, used to measure expected volatility for future stock option grants.

        The risk-free interest rate assumption is based upon observed interest rates on the United States government securities appropriate for the expected term of our employee stock options.

        The dividend yield assumption is based on our history and expectation of dividend payouts for which no cash dividends have been declared or paid on our common stock, and for which none are anticipated in the foreseeable future.

        As stock-based compensation expense recognized in our accompanying consolidated statements of operations is based on awards ultimately expected to vest, the amount has been reduced for estimated forfeitures. ASC 718 requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Forfeitures were estimated based on our historical experience and future expectations.

        Compensation expense for non-employee stock-based awards is recognized in accordance with ASC 718 and FASB ASC 505, Equity. Stock option awards issued to non-employees are accounted for at fair value using the Black-Scholes option pricing model. Management believes that the fair value of the stock options is more reliably measured than the fair value of the services received. We record compensation expense based on the then-current fair value of the stock options at each financial reporting date. Compensation recorded during the service period is adjusted in subsequent periods for changes in the stock options' fair value until the earlier of the date at which the non-employee's performance is complete or a performance commitment is reached, which is generally when the stock award vests. There was $30, $372 and $515 of stock-based compensation expense recognized for non-employee stock-based awards for the years ended December 31, 2013, 2012 and 2011, respectively.

Income taxes

        We account for income taxes in accordance with FASB ASC 740, Accounting for Income Taxes ("ASC 740"), which requires the recognition of deferred tax assets and liabilities for the future consequences of events that have been recognized in our accompanying consolidated financial statements or tax returns. The measurement of the deferred items is based on enacted tax laws. In the event the future consequences of differences between financial reporting bases and the tax bases of our assets and liabilities result in a deferred tax asset, ASC 740 requires an evaluation of the probability of being able to realize the future benefits indicated by such asset. A valuation allowance related to a deferred tax asset is recorded when it is more likely than not that some portion or the entire deferred tax asset will not be realized. As part of the process of preparing our accompanying consolidated financial statements, we are required to estimate our income taxes in each of the jurisdictions in which

F-17

2. Summary of significant accounting policies (Continued)

we operate. We also assess temporary differences resulting from differing treatment of items, such as deferred revenue, for tax and accounting differences. We record a valuation allowance to reduce the deferred tax assets to the amount of future tax benefit that is more likely than not to be realized.

        ASC 740 prescribes a recognition threshold and measurement methodology to recognize and measure an income tax position taken, or expected to be taken, in a tax return. The evaluation of a tax position is based on a two-step approach. The first step requires an entity to evaluate whether the tax position would "more likely than not" be sustained upon examination by the appropriate taxing authority. The second step requires the tax position be measured at the largest amount of tax benefit that is greater than 50% likely of being realized upon ultimate settlement. In addition, previously recognized benefits from tax positions that no longer meet the new criteria would no longer be recognized. Changes in recognition or measurement are reflected in the period in which the change occurs.

Non-controlling interests

        Non-controlling interests are comprised of minority holdings in Concourse Communications Detroit, LLC ("CCG Detroit"), Chicago Concourse Development Group, LLC ("CCDG") and Boingo Holding Participacoes Ltda ("BHPL").

        Under the terms of the limited liability company ("LLC") agreement for CCG Detroit ("Detroit Operating Agreement") profits and losses are allocated to the controlling and non-controlling owners based on specified terms in the Detroit Operating Agreement which reflect the relative risk and reward of each owner. The profit and loss allocation in the Detroit Operating Agreement specifies that the non-controlling owners' allocated profits are limited to the fixed distribution amounts and losses are limited to the non-controlling owners capital account balance with losses in excess of their capital account being fully allocated to the controlling common unit holder. There is no specified term in the Detroit Operating Agreement, but the term of the annual fixed distribution obligation to the non-controlling owner is the same as the term of the venue agreement between CCG Detroit and Detroit Metropolitan Wayne County Airport—which has a seven year initial term with options to extend for an additional four years. We allocate profits and losses in CCG Detroit based on the attribution in the Detroit Operating Agreement. CCG Detroit has generated losses which reduced the non-controlling owners capital account to zero in 2009 resulting in an allocation to the controlling interest holder all operating losses and deficits created by the annual fixed distributions to the non-controlling interest holder. The fixed distributions were terminated during September 2013 concurrent with the termination of CCG Detroit's agreement with Detroit Metropolitan Wayne County Airport. For the years ended December 31, 2013, 2012 and 2011, we made distributions of $48, $121 and $85, respectively, to non-controlling interest holders of CCG Detroit.

        Under the terms of the LLC agreement for CCDG, we are required to distribute annually to the CCDG non-controlling interest holders 30% of allocated net profits less capital expenditures of the preceding year. For the years ended December 31, 2013, 2012 and 2011, we made distributions of $560, $557 and $462, respectively, to non-controlling interest holders of CCDG.

        BHPL was formed at the end of 2012. Under the terms of the LLC agreement for BHPL, we attributed profits and losses to the non-controlling interest in BHPL in proportion to their holdings.

2. Summary of significant accounting policies (Continued)

For the year ended December 31, 2013, we made no distributions to the non-controlling interest holder of BHPL.

Convertible preferred stock

        The convertible preferred stock contained puttable redemption features and deemed liquidation preferences upon a change-in-control, which were considered outside of the control the Company. Accretion of related issuance costs and dividends were recorded as a charge against retained earnings, or in the absence of retained earnings by charges against additional paid-in capital until fully depleted, then against the accumulated deficit. We accrete issuance costs and dividends to the earliest redemption date. For the year ended December 31, 2011, we accreted our convertible preferred stock through to their conversion date into common stock on May 3, 2011 in connection with our IPO. At December 31, 2013 and 2012, we had no preferred stock issued or outstanding.

Warrants exercisable into convertible preferred stock

        We account for preferred stock warrants as liabilities when the underlying preferred stock contains either puttable or mandatorily redeemable features. We issued warrants which were exercisable into the Series B convertible preferred stock in connection with capital lease arrangements. We determined that the preferred stock warrants contained puttable features as a result of the redemption provisions and deemed liquidation preferences upon a change-in-control. Accordingly, the warrants were recorded as a non-current liability and were carried at their fair value at date of issuance with decreases or increases in fair value at each reporting date recorded as other income or expense through to the final measurement date upon the exercise of the warrants. The warrants were exercisable either through cash payment of the exercise price or through net-share settlement at the option of the holder. Our preferred stock warrants outstanding of 25,196 were exercised and converted under the net-share settlement provisions into 20,172 shares of our common stock on May 3, 2011, in connection with our IPO.

Net (loss) income per share attributable to common stockholders

        Basic net (loss) income per share attributable to common stockholders is calculated by dividing (loss) income attributable to common stockholders by the weighted average number of shares of common stock outstanding during the period. Diluted net income per share attributable to common stockholders adjusts the basic weighted average number of shares of common stock outstanding for the potential dilution that could occur if stock options, RSUs, common stock warrants, preferred stock warrants and the convertible preferred stock were exercised or converted into common stock. Our convertible preferred stockholders were entitled to receive dividends and were not contractually obligated to share in our net income with common stockholders. The common stockholders are not entitled to receive any dividends.

Segment and geographic information

        We operate as one reportable segment; a service provider of mobile Internet solutions across our managed and operated network and aggregated network for mobile devices such as laptops, smartphones, tablet computers and other wireless-enabled consumer devices. This single segment is

2. Summary of significant accounting policies (Continued)

consistent with the internal organization structure and the manner in which operations are reviewed and managed by our Chief Executive Officer, the chief operating decision maker.

        Revenue is predominantly generated and all significant long-lived tangible assets are held in the United States of America. We do not disclose sales by geographic area because to do so would be impracticable. The following is a summary of our revenue by primary revenue source:

	Year Ended December 31,
	2013		2012		2011
Revenue:
Wholesale	$	49,942	$	49,495	$	43,707

Reclassifications

        Certain 2012 and 2011 amounts have been reclassified to conform to the current year presentation.

Recent accounting pronouncements

        In July 2013, the FASB issued ASU 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists ("ASU 2013-11"). This ASU requires the netting of unrecognized tax benefits (UTBs) against a deferred tax asset for a loss or other carryforward that would apply in the settlement of the uncertain tax positions. The UTBs will be netted against all available same-jurisdiction loss or other tax carryforwards that would be utilized, rather than only against carryforwards that are created by the UTBs. ASU 2013-11 will require prospective application with optional retrospective application, and will be effective for reporting periods beginning after December 15, 2013. Early adoption is permitted. We have effectively adopted the provisions of this requirement as of the date of issuance of ASU 2013-11 as we have historically presented our UTBs as a reduction of our deferred tax assets for a loss or other carryforward rather than as a liability when the uncertain tax position would reduce the loss or other carryforward under the tax law.

        In February 2013, the FASB issued ASU 2013-02, Comprehensive Income—Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income ("ASU 2013-02"). This ASU requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income ("AOCI") by component. In addition, an entity is required to present, either on the face of the statement where net income (loss) is presented or in the notes, significant amounts reclassified out of AOCI by the respective line items of net income (loss) but only if the amount reclassified is required under GAAP to be reclassified to net income (loss) in its entirety in the same reporting period. For other amounts that are not required under GAAP to be reclassified in their entirety to net income (loss), an entity is required to cross-reference to other disclosures required under GAAP that provide additional detail about those amounts. ASU 2013-02 was effective prospectively for reporting periods

3. Acquisitions

Electronic Media Systems, Inc. and Advanced Wireless Group, LLC

        On October 31, 2013, we acquired all outstanding stock of Electronic Media Systems, Inc. and all membership interests in its subsidiary, Advanced Wireless Group, LLC, not otherwise owned by Electronic Media Systems, Inc. such that we are now the beneficial owner of all membership interests of Advanced Wireless, Group, LLC (collectively, "AWG"). AWG operates public Wi-Fi in seventeen U.S. airports including Los Angeles International, Charlotte/Douglas International, Miami International, Minneapolis-St. Paul International, Detroit Metropolitan Airport, and Boston's Logan International. We have included the operating results of AWG in our consolidated financial statements since the date of acquisition.

        The acquisition has been accounted for under the acquisition method of accounting in accordance with FASB ASC 805, Business Combinations. As such, the assets acquired and liabilities assumed are recorded at their acquisition-date fair values. The total purchase price was $17,380, which includes cash paid at closing, holdback consideration to be paid and the fair value of additional contingent consideration that would be due and payable upon the successful extension of a specified airport Wi-Fi contract. The total purchase price includes estimated net equity adjustments that may be subject to additional adjustments.

        The fair value of the contingent consideration is based on Level 3 inputs. Further changes in the fair value of the contingent consideration will be recorded through operating (loss) income. We allocated the excess of the purchase price over the fair value of assets acquired and liabilities assumed to goodwill, which is primarily not deductible for tax purposes. The goodwill arising from the AWG acquisition is attributable primarily to expected synergies and other benefits, including the acquired workforce, from combining AWG with us.

        The deferred tax liabilities are provisional pending the filing of AWG's final short period 2013 tax returns. The contingent consideration was valued at the date of acquisition using a discount rate of 3.1% and is expected to be paid in 2014. The identifiable intangible assets were primarily valued using the excess earnings, relief from royalty, with-and-without and replacement cost methods using discount rates ranging from 12.0% to 14.0% and royalty rates of 0.5%.

Endeka Group, Inc.

        On February 22, 2013, we acquired all outstanding stock of Endeka Group, Inc. ("Endeka"). Endeka is a provider of commercial wireless broadband and IPTV services at certain military bases, as well as Wi-Fi services to certain federal law enforcement training facilities. We acquired Endeka because Endeka's portfolio of venues and management team are natural additions to our managed network business. We have included the operating results of Endeka in our consolidated financial statements since the date of acquisition.

        The acquisition has been accounted for under the acquisition method of accounting in accordance with FASB ASC 805. As such, the assets acquired and liabilities assumed are recorded at their

acquisition-date fair values. The total purchase price was $6,498, which includes cash paid at closing, holdback consideration to be paid and the fair value of additional contingent consideration comprised of two components: (i) a payment ("Build Payment") if the amount of the capital expenditures incurred for the substantial completion of a specified build project is less than a target; and (ii) a payment ("Milestone Payment") based on revenue generated by certain contracts in fiscal year 2014. There is no maximum to the contingent consideration payments for the Milestone Payment. We do not expect to make any payments associated with the Build Payment. The holdback consideration will be paid in 2014 and the Milestone Payment will be paid on February 28, 2015.

        The fair value of the contingent consideration is based on Level 3 inputs. Further changes in the fair value of the contingent consideration will be recorded through operating (loss) income. We allocated the excess of the purchase price over the fair value of assets acquired and liabilities assumed to goodwill, which is not deductible for tax purposes. The goodwill arising from the Endeka acquisition is attributable primarily to expected synergies and other benefits, including the acquired workforce, from combining Endeka with us.

        The contingent consideration was valued at the date of acquisition using a discounted cash flow method with probability weighted cash flows and a discount rate of 50.5%. The identifiable intangible assets were primarily valued using the excess earnings, relief from royalty, and replacement cost methods using discount rates ranging from 40.0% to 50.0% and royalty rates ranging from 0.5% to 1.5%, where applicable.

Cloud 9 Wireless, Inc.

        On August 6, 2012, we acquired the assets of Cloud 9 Wireless, Inc. ("Cloud 9") for $3,500 plus the assumption of certain liabilities. Cloud 9 provides Wi-Fi sponsorship and location-based advertising at airports, hotels, bars and restaurants, and recreational areas in the U.S. and Canada. The acquisition has been accounted for under the acquisition method of accounting in accordance with the FASB ASC 805. The excess of the acquisition consideration over the fair value of assets acquired and liabilities assumed is allocated to goodwill, which is deductible for tax purposes. Goodwill is attributable primarily to expected synergies and other benefits, including the acquired workforce, from combining Cloud 9 with us. Cloud 9 was consolidated into our results of operations starting August 6, 2012, the acquisition date. Cloud 9 has been integrated into the Company's product offering; therefore, it is not practical to disclose actual and pro forma financial results for Cloud 9 since the acquisition.

        The following table summarizes the allocation of the total purchase price as of August 6, 2012:

Current assets	$	899
Property, plant and equipment		65
Intangible and other assets		1,758
Goodwill		1,232
Current liabilities		(454	)
Net assets acquired	$	3,500

        The intangible assets are all definite-lived intangibles and are recognized on a straight-line basis over their weighted average lives of approximately 5 years.

Restricted cash		30		—		30
Total assets	$	39,031	$	44,018	$	83,049

        Our marketable securities utilize Level 2 inputs and consist primarily of corporate securities which include commercial paper and corporate debt instruments including notes issued by foreign or domestic corporations which pay in U.S. dollars and carry a rating of A or better. We have evaluated the various types of securities in our investment portfolio to determine an appropriate fair value hierarchy level based upon trading activity and the observability of market inputs. Due to variations in trading volumes and the lack of quoted market prices in active markets, our fixed maturities are classified as Level 2 securities.

        The fair value of our fixed maturity marketable securities is derived through the use of a third party pricing source or recent reported trades for identical or similar securities, making adjustments through the reporting date based upon available market observable data.

        The Company used the income approach to value the contingent consideration as of December 31, 2013. The contingent consideration used a discounted cash flow method with probability weighted cash flows and a discount rate of 25.0% for Endeka. The contingent consideration used a discount rate of 3.1% for AWG. The following table presents a reconciliation of the beginning and ending amounts related to the fair value of contingent consideration for the Endeka and AWG acquisitions, categorized as Level 3:

10. Stockholders' equity

Convertible preferred stock

        Each share of Series A, Series A-2, Series B and Series C convertible preferred stock was immediately convertible, at the holder's option, into shares of common stock based on the formula of the issuance price divided by the conversion price. The conversion price was $3.00 for Series A and B convertible preferred stock, $4.026072935 for Series A-2 convertible preferred stock and $4.95835 for Series C convertible preferred stock. Each share of Series A and Series B convertible preferred stock was convertible into one share of common stock. Series A-2 convertible preferred stock was convertible into shares of common stock as obtained by multiplying the number of shares of the convertible stock by $4.30 and dividing the result by the conversion price of $4.026072935 per share, which approximates a 1 for 1.07 shares of common stock conversion rate. Series C convertible preferred stock was convertible into shares of common stock as obtained by multiplying the number of shares of the convertible stock by $5.95 and dividing the result by the conversion price of $4.95835 per share, which approximates a 1 for 1.2 shares of common stock conversion rate. Conversion of each share of Series A, Series A-2, Series B and Series C convertible preferred stock was automatic upon the completion of our IPO.

        The holders of the Series A, Series A-2, Series B and Series C convertible preferred stock were also entitled to receive cumulative dividends, whether or not earned or declared, out of funds legally available therefore, at the rate of $0.15 per share per annum for the Series A and Series B convertible preferred stock, $0.215 for the Series A-2 convertible preferred stock and $0.2975 for the Series C convertible preferred stock (the "accruing dividends"). Accruing dividends accrued on each share of convertible preferred stock from the date of issuance until the earlier of (i) a liquidation, dissolution or winding up of the company, including an acquisition, consolidation or merger, or the sale of all or substantially all of the assets of the company (a "liquidation event") and (ii) the date of redemption. We accrued dividends in the year ended December 31, 2011, which were accreted in the respective carrying values of the convertible preferred stock before they were converted into common stock.

Reserve for unissued shares

        At December 31, 2013 and 2012, we are authorized to issue up to 100,000,000 shares of common stock. We are required to reserve and keep available out of our authorized but unissued shares of common stock such number of shares sufficient to effect the exercise of all outstanding common stock warrants, plus shares granted and available for grant under our Amended and Restated 2001 Stock Incentive Plan (the "2001 Plan") and 2011 Equity Incentive Plan (the "2011 Plan").

        The amount of such shares of common stock reserved for these purposes is as follows:

	December 31, 2013		December 31, 2012
	(in thousands)
Outstanding stock options under the 2001 Plan		1,859		2,345
Outstanding stock options under the 2011 Plan		3,096		2,700

10. Stockholders' equity (Continued)

Note receivable from stockholder

        During 2002, we granted 290,000 shares of restricted common stock to an officer at the deemed fair value of $0.30 per share in exchange for cash proceeds of approximately $9 and issuance of a partial recourse note ("Note") of approximately $78 payable with an interest rate equal to the applicable federal rate. On January 11, 2011, we forgave the Note and the principal and interest outstanding of $103 was expensed as compensation. Interest accrued on the Note, and was included in interest and other income (expense), net in the accompanying consolidated statements of operations.

Treasury stock

        On July 29, 2011, we approved the retirement of all 1,256,608 outstanding shares of treasury stock. The treasury stock, at cost, of $4,575 was transferred to additional paid-in capital in the accompanying consolidated statements of convertible preferred stock and stockholder's equity (deficit).

Common stock warrants

        On June 28, 2011, our 26,322 common stock warrants outstanding were exercised into 21,525 shares of common stock on a net exercise basis.

11. Income taxes

        The income tax expense (benefit) by jurisdiction consists of the following for the years ended December 31:

        We have a foreign subsidiary in the United Kingdom, which has generated losses since inception resulting in an $644 deferred tax asset with a corresponding valuation allowance as of December 31, 2013. We also have a majority owned foreign subsidiary in Brazil, which has generated losses since inception resulting in a $69 deferred tax assets with a corresponding valuation allowance as of December 31, 2013. Foreign loss before income taxes was $559, $61, and $45 for 2013, 2012, and 2011, respectively.

        Deferred income tax reflects the tax effects of temporary differences that gave rise to significant portions of our deferred tax assets and liabilities and consisted of the following for the years ended December 31, 2013 and December 31, 2012; respectively:

11. Income taxes (Continued)

        In assessing the realizability of deferred tax assets, we consider whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. As of December 31, 2013 and 2012, we had federal net operating loss carryforwards of approximately $20,389 and $15,283, respectively, state net operating loss carryforwards of approximately $37,153 and $29,955, respectively, and foreign net operating loss carryforwards of $3,425 and $1,588, respectively. The federal net operating loss carryforwards will begin to expire in 2025, and our foreign net operating loss carryforwards have an indefinite life. Our state net operating loss carryforwards are principally related to California net operating losses and will begin to expire in 2015. Our ability to utilize certain of our net operating loss carryforwards may be limited in the event that a change in ownership, as defined in the Internal Revenue Code, occurs in the future.

        The following table sets forth the changes in the valuation allowance, for all periods presented:

	Valuation Allowance
Balance, December 31, 2010	$	3,109
Decrease credited to operations		(1,287	)
Balance, December 31, 2011		1,822
Additions charged to operations		51
Decrease credited to operations		(204	)
Balance, December 31, 2012		1,669
Additions charged to operations		2,294
Decrease credited to operations		—
Balance, December 31, 2013	$	3,963

        During the year ended December 31, 2013, we recorded a $2,294 increase in our valuation allowance on our federal deferred tax assets, primarily due to changes in our expectations regarding our ability to realize these deferred tax assets. This resulted from a determination that it was more likely than not that certain federal net deferred tax assets would not be realized. We recently won some significant new contracts for the build out of residential broadband and IPTV networks for troops stationed on military bases that will now require us to make investments and incur losses in advance of experiencing any direct benefit from them including generation of revenues.

        During the year ended December 31, 2011, we recorded a $1,287 release to the valuation allowance on our state net deferred tax assets, due to changes in our expectations regarding our ability to realize these deferred tax assets. This resulted from a determination that it was more likely than not that certain state net deferred tax assets would be realized. The remaining valuation allowance primarily relates to the deferred tax assets for state net operating losses that the Company believes is not more likely than not to be realized before expiration.

        In reaching the determination of the valuation allowance, we have evaluated all significant available positive and negative evidence including, but not limited to, our three year cumulative results, trends in our business, expected future results and the character, amount and expiration periods of our net deferred tax assets. The underlying assumptions we used in forecasting future income required significant judgment and took into account our recent performance.

11. Income taxes (Continued)

        During 2013, 2012 and 2011, we realized excess windfall tax benefits of approximately $55, $2,190 and $246, respectively, from stock option exercises. These benefits decreased income taxes payable and were recorded as an increase to additional paid-in capital in the accompanying consolidated balance sheets. In accordance with the reporting requirements under ASC 718, we did not include excess windfall tax benefits resulting from stock option exercises as components of our gross deferred tax assets and corresponding valuation allowance disclosures, as tax attributes related to those windfall tax benefits should not be recognized until they result in a reduction of taxes payable. The tax effected amount of gross unrealized net operating loss carryforwards excluded under ASC 718 was approximately $5,847 at December 31, 2013. When realized, those excess windfall tax benefits are credited to additional paid-in capital.

        We recognized interest and penalties related to income tax matters in income taxes which were not material during the years ended December 31, 2013, 2012, and 2011.

        We identify, evaluate and measure all uncertain tax positions taken or to be taken on tax returns and record liabilities for the amount of these positions that may not be sustained, or may only partially be sustained, upon examination by the relevant taxing authorities. Although we believe that our estimates and judgments were reasonable, actual results may differ from these estimates. Some or all of these judgments are subject to review by the taxing authorities. As of December 31, 2013 and 2012, we had $445 and $392 in uncertain tax positions, respectively, $106 of which is a reduction to deferred tax assets, which is presented net of uncertain tax positions, in the accompanying consolidated balance sheets. We accrue interest and penalties related to unrecognized tax benefits as a component of income taxes. As of December 31, 2013, we have accrued $53 for related interest, net of federal income tax benefits, and penalties recorded in income tax expense on our consolidated statements of operations. There were no significant accrued interest and penalties as of December 31, 2012.

        A reconciliation of our unrecognized tax benefits, excluding interest and penalties, is as follows:

	Uncertain Tax Positions
Balance, December 31, 2012	$	392
Additions for current period tax positions		—
Balance, December 31, 2013	$	392

        Our annual income taxes and the determination of the resulting deferred tax assets and liabilities involve a significant amount of judgment. Our judgments, assumptions and estimates relative to current income taxes take into account current tax laws, their interpretation of current tax laws and possible outcomes of current and future audits conducted by foreign and domestic tax authorities. We operate within federal, state and international taxing jurisdictions and are subject to audit in these jurisdictions. These audits can involve complex issues which may require an extended period of time to resolve. We are subject to taxation in the United States and in various states. Our tax years 2010 and forward are subject to examination by the IRS and our tax years 2007 and forward are subject to examination by material state jurisdictions. However, due to prior year loss carryovers, the IRS and state tax authorities may examine any tax years for which the carryovers are used to offset future taxable income. We are currently subject to examination by the IRS for our 2011 tax year. Although the ultimate outcome is

unknown, we believe that any adjustments that may result from examination is not likely to have a material, adverse effect on our consolidated results of operations, financial position or cash flows.

12. Commitments and contingencies

Capital and operating leases

        We lease space in managed and operated locations, primarily airports, under exclusive long-term, non-cancellable contracts to provide Wi-Fi connectivity and cellular phone access to our DAS network. Minimum rent expense is recorded on a straight-line basis over the term of the lease. Rent expense from our leases for the years ended December 31, 2013, 2012 and 2011 was $20,234, $16,760 and $15,511, respectively.

        We lease equipment, primarily data communication equipment and database software under non-cancellable capital leases that expired in October 2011. The leases were collateralized by the equipment under the lease. Interest expense associated with the capital leases for the years ended December 31, 2013, 2012 and 2011 was $15, $11 and $8, respectively. We also lease office space under non-cancellable operating leases. Rent expense for our leases of office facilities for the years ended December 31, 2013, 2012 and 2011 was $1,227, $1,209 and $1,323, respectively. Included in rent expense for the years ended December 31, 2013, 2012 and 2011 was sublease income of $54, $52 and $32, respectively.

        Future minimum lease obligations under non-cancellable operating and capital leases at December 31, 2013 are as follows:

Years ended December 31,	Capital Leases			Operating Leases and Airport Guarantees
2014	$	662		$	10,819
2015		383			8,830
2016		312			6,985

Less: Amounts representing interest ranging from 1.0% to 6.5%		(439	)
Minimum lease payments	$	999
Current portion	$	526
Non-current portion	$	473

Letters of credit

        In October 2013, we entered into a Letter of Credit ("Letter of Credit") Authorization agreement with Silicon Valley Bank ("SVB") for a one year term. The Letter of Credit is irrevocable and serves as

(In thousands, except shares and per share amounts)

12. Commitments and contingencies (Continued)

a performance guarantee that will allow our customer to draw up to $1,800 if we are in default. There have been no drafts drawn under this Letter of Credit as of December 31, 2013.

Legal proceedings

        From time to time, we may be subject to claims, suits, investigations and proceedings arising out of the normal course of business. We are not currently a party to any litigation that we believe could have a material adverse effect on our business, financial position, results of operations or cash flows.

Indemnification

        Indemnification provisions in our third-party service provider agreements provide that we will indemnify, hold harmless, and reimburse the indemnified parties on a case-by-case basis for losses suffered or incurred by the indemnified parties in connection with any claim by any third party as a result of our website, advertising, marketing, payment processing, collection or customer service activities. The maximum potential amount of future payments we could be required to make under these indemnification provisions is undeterminable. We have never paid a claim, nor have we been sued in connection with these indemnification provisions. At December 31, 2013 and 2012, we have not accrued a liability for these guarantees, because the likelihood of incurring a payment obligation in connection with these guarantees is not probable.

Employment contracts

        We have entered into employment contracts with six of our officers. These contracts generally provide for severance benefits, including salary continuation, if employment is terminated by us for substantial cause or by the officer for convenience. In addition, in order to assure that they would continue to provide independent leadership consistent with our best interests in the event of an actual or threatened change in control, the contract also generally provides for certain protections in the event of such a change in control. These protections include the payment of certain severance benefits, including salary continuation, upon the termination of employment following a change in control.

13. Stock repurchases

        On April 1, 2013, the Company approved a stock repurchase program to repurchase up to $10,000 of the Company's common stock in the open market, exclusive of any commissions, markups or expenses. The stock repurchased will be retired and will resume the status of authorized but unissued shares of common stock. During the year ended December 31, 2013, we repurchased and retired approximately 722,000 shares under this program for approximately $4,820, excluding commissions paid, at an average price per share of $6.68. As of December 31, 2013, the remaining approved amount for repurchases was approximately $5,180.

14. Stock incentive plans

        In March 2011, our board of directors approved the 2011 Plan. The 2011 Plan provides for the grant of incentive and nonstatutory stock options, stock appreciation rights, restricted shares of our common stock, stock units, and performance cash awards. As of January 1^st of each year, the number of shares of common stock reserved for issuance under the 2011 Plan shall automatically be increased by a number equal to the lesser 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) as determined by our board of directors. As of December 31, 2013, 7,108,013 shares of common stock are reserved for issuance. As of December 31, 2013, options to purchase 5,026,486 shares of common stock and 799,289 RSUs have been granted under the 2011 Plan.

        No further awards will be made under our 2001 Plan and it will be terminated. Options outstanding under the 2001 Plan will continue to be governed by their existing terms. As of December 31, 2013, options to purchase 1,858,543 shares of common stock were outstanding under the 2001 Plan.

        The following table summarizes our stock-based compensation expense included in the consolidated statements of operations for 2013, 2012 and 2011:

	Years ended December 31,
	2013		2012		2011
Network operations	$	888	$	352	$	463

General and administrative		2,193		1,460		1,733
Total stock-based compensation expense	$	4,506	$	2,735	$	3,423

Stock option awards

        We grant stock option awards to both employees and non-employee directors. The grant date for these awards is the same as the measurement date. The stock option awards generally vest over a four year service period with 25% vesting when the individual completes 12 months of continuous service and the remaining 75% vesting monthly thereafter. These awards are valued as of the measurement date and the stock-based compensation expense, net of estimated and actual forfeitures, is recognized

on a straight-line basis over the requisite service period. A summary of the activity for stock option awards for 2013, 2012 and 2011 is presented below:

	Number of Options (000's)			Weighted Average Exercise Price		Weighted- Average Remaining Contract Life (years)		Aggregate Intrinsic Value
Outstanding at December 31, 2010		5,288		$	1.25		6.3	$	38,279

Outstanding at December 31, 2012		5,045		$	6.50		6.4	$	14,742
Granted		1,351		$	6.73
Exercised		(461	)	$	1.33
Canceled/forfeited		(980	)	$	10.20
Outstanding at December 31, 2013		4,955		$	6.31		6.6	$	9,535
Vested, exercisable and expected to vest at December 31, 2013		4,788		$	6.25		6.5	$	9,520
Exercisable at December 31, 2013		2,739		$	4.52		4.8	$	9,329

        The aggregate intrinsic value in the table above represents the difference between the estimated fair value of our common stock at December 31, 2013 and the option exercise price, multiplied by the number of in-the-money options at December 31, 2013. The intrinsic value changes are based on the estimated fair value of our common stock.

        Stock options to purchase 461,000, 1,899,000 and 1,015,000 shares of our common stock were exercised during the years ended December 31, 2013, 2012 and 2011 for cash proceeds of $614, $2,573 and $1,028, respectively. The total intrinsic value of stock options exercised for the years ended December 31, 2013, 2012 and 2011 was $2,662, $14,901 and $9,754, respectively. We realized $55, $2,190 and $246 of tax benefits for the deductions from stock option exercises during 2013, 2012 and 2011, respectively.

        The weighted average grant date fair value of options granted for the years ended December 31, 2013, 2012 and 2011 was $6.60, $8.10 and $6.68, respectively.

        At December 31, 2013, the total remaining stock-based compensation expense for unvested stock option awards is $7,345, which is expected to be recognized over a weighted average period of 2.95 years.

Restricted stock unit awards

        During the year ended December 31, 2013, we issued RSUs to executive and non-executive personnel and members of our board of directors. The executive and non-executive RSUs generally vest over a two year period with 50% of the RSUs vesting when the individual completes 12 months of continuous service and the remaining 50% vesting on a quarterly basis thereafter. The board of directors RSUs generally vests over a one year period for existing members and 25% per year over a four year period for new members. A summary of the RSU activity in 2013 is as follows:

	Number of Shares (000's)			Weighted Average Grant Date Fair Value
Nonvested at December 31, 2012		—		$	—
Granted		799		$	6.21
Vested		(6	)	$	6.39
Canceled/forfeited		(40	)	$	6.05
Nonvested at December 31, 2013		753		$	6.22

        The RSUs that vested during the year ended December 31, 2013 resulted from the accelerated vesting for an employee that retired during 2013. At December 31, 2013, the total remaining stock-based compensation expense for unvested RSU awards is $2,750, which is expected to be recognized over a weighted average period of 1.4 years.

15. Employee benefit plan

        We have a defined contribution savings plan in accordance with Section 401(k) of the Internal Revenue Code. This plan covers substantially all employees who meet the IRS requirements and allows participants to defer a portion of their annual compensation on a pre-tax basis. Company contributions to the plan may be made at the discretion of the board of directors. Employer contributions of $330, $347 and $285 were made to the plan by us in 2013, 2012 and 2011, respectively.

        For the year ended December 31, 2013, we excluded all stock options and RSUs from the computation of diluted net loss per share due to the net loss for the period. The following outstanding securities were not included in the computation of diluted net income per share as the inclusion would have been anti-dilutive for the years ended December 31, 2012 and 2011:

Dawn Callahan

10960 Wilshire Blvd., Suite 800

Los Angeles, CA 90024

Dear Dawn:

Boingo Wireless, Inc. (the “Company”) is pleased to offer you continuing employment on the following terms, effective as of January 1, 2013 (the “Effective Date”).

1.Position.  Your title and position with the Company will be Senior Vice President of Marketing and Sales, and you will report directly to the Chief Executive Officer.  This is a full-time position and your place of employment will be our headquarters in Los Angeles.  While you render services to the Company, you will not engage in any other employment, consulting or other business activity (whether full-time or part-time) that would create a conflict of interest with the Company.  By signing this Agreement, you confirm to the Company that you have no contractual commitments or other legal obligations that would prohibit you from performing your duties for the Company.

2.Cash Compensation.  Beginning on the Effective Date, your annual base salary will be $240,000 per year, payable in accordance with the Company’s standard payroll schedule.  This salary will be subject to adjustment pursuant to the Company’s employee compensation policies in effect from time to time. In addition, you will continue to be eligible to be considered for a cash-incentive bonus for each fiscal year of the Company.  The bonus (if any) will be awarded based on objective or subjective criteria established and approved by the Compensation Committee of the Board.  Your target bonus will be equal to 55% of your annual base salary, measured as of the last day of each fiscal year.  Any bonus for a fiscal year will be paid within 2½ months after the close of that fiscal year, but only if you are still employed by the Company at the time of payment.  The determinations of the Compensation Committee with respect to your bonus will be final and binding.

3.Employee Benefits.  As a regular employee of the Company, you will be eligible to participate in the Company’s standard employee benefits programs, as such are in effect from time to time.  In addition, you will be entitled to paid vacation in accordance with the Company’s vacation policy, as in effect from time to time.

4.Payments Upon Termination.  If your employment with the Company terminates other than as set forth in Section 5 below, then (a) all vesting will cease immediately with respect to your then-outstanding Equity Awards and (b) the only amounts payable to you by the Company will be (i) any unpaid base salary due for periods prior to the date of termination of your employment and (ii) any accrued but unused vacation through such termination date.  Such payments, if any, will be made promptly upon termination and within the period of time mandated by law.

5.Severance Benefits.

(a)General.  If you are subject to an Involuntary Termination, then you will be entitled to the benefits described in this Section 5.  However, you will not be entitled to any of the benefits described in this Section 5 unless you have (i) returned all Company property in your possession, (ii) resigned as a member of the Board and of the boards of directors of all of the Company’s subsidiaries, to the extent applicable, and (iii) executed a general release of all claims that you may have against the Company or persons affiliated with the Company, substantially in the form attached hereto as Exhibit A (the “Release”).  You must execute and return the release on or before the date specified by the Company in the Release (the “Release Deadline”).  The Release Deadline will in no event be later than fifty (50) days after your Separation.  If you fail to return the Release on or before the Release Deadline, or if you revoke the Release, then you will not be entitled to the benefits described in this Section 5.

Notwithstanding the foregoing, the Company may immediately discontinue all benefits or revoke any vesting acceleration described in this Section 5 (in addition to pursuing all other legal and equitable remedies) if you breach the Employee Inventions and Confidentiality Agreement or the Mutual Agreement to Arbitrate Claims between you and the Company that you previously signed (collectively, the “Confidentiality Agreement”), a copy of which is attached hereto as Exhibit B, the terms of Section 7 below or any other material agreement with the Company that by its terms continues in force following your Separation.

(b)Termination Not in Connection With Change in Control.  Subject to the requirements set forth in Section 5(a) above, if you experience an Involuntary Termination either prior to a Change in Control or more than twelve (12) months after a Change in Control, then you will be entitled to the following:

(i)Salary Continuation.  The Company will continue to pay your base salary for a period beginning on the day after your Separation and ending on the date nine (9) months after your Separation. Your base salary will be paid at the rate in effect at the time of your Separation and in accordance with the Company’s standard payroll procedures.  Subject to the Company’s having first received an effective Release pursuant to Section 5(a) above, the salary continuation payments will commence within sixty (60) days after your Separation and, once they commence, will include any unpaid amounts accrued from the date of your Separation.  However, if the sixty (60)-day period described in the preceding sentence spans two calendar years, then the payments will in any event begin in the second calendar year.

2

(ii)Additional Payment in Lieu of Health Benefit.  The Company will pay you a lump sum amount equal to the product of (A) nine (9) and (B) the monthly amount the Company was paying on behalf of you and your eligible dependents pursuant to the Company’s health insurance plans in which you or your dependents were participants as of the day of your Separation.  Subject to the Company’s having first received an effective Release pursuant to Section 5(a) above, such payment will be made within sixty (60) days after your Separation; however, if such sixty (60)-day period spans two calendar years, then the payment will be made in the second calendar year.

(iii)Equity Acceleration.  You will receive nine (9) months of vesting credit under your then-outstanding Equity Awards; provided, however, that in the event acceleration of the settlement or distribution date of an award would result in additional taxes and penalties under Section 409A of the Code, then the vesting of such award shall accelerate but settlement or distribution of award shares (or cash, if applicable) shall occur on the date(s) specified in the agreement governing the award.

(c)Termination in Connection With Change in Control.  Subject to the requirements set forth in Section 5(a) above, if you experience an Involuntary Termination within twelve (12) months following a Change in Control, then you will be entitled to the following:

(i)Salary Continuation.  The Company will continue to pay your base salary for a period beginning on the day after your Separation and ending on the date twelve (12) months after your Separation. Your base salary will be paid at the rate in effect at the time of your Separation and in accordance with the Company’s standard payroll procedures.  Subject to the Company’s having first received an effective Release pursuant to Section 5(a) above, the salary continuation payments will commence within sixty (60) days after your Separation and, once they commence, will include any unpaid amounts accrued from the date of your Separation.  However, if the sixty (60)-day period described in the preceding sentence spans two calendar years, then the payments will in any event begin in the second calendar year.

(ii)Target Bonus.  The Company will pay you a lump sum equal to your annual target bonus in the year of your Separation.  Subject to the Company’s having first received an effective Release pursuant to Section 5(a) above, such payment will be made within sixty (60) days after your Separation; however, if such sixty (60)-day period spans two calendar years, then the payment will be made in the second calendar year.

(iii)Additional Payment in Lieu of Health Benefit.  The Company will pay you a lump sum amount equal to the product of (A) twelve (12) and (B) the monthly amount the Company was paying on behalf of you and your eligible dependents pursuant to the Company’s health insurance plans in which you or your dependents were participants as of the day of your Separation.  Subject to the Company’s having first received an effective Release pursuant to Section 5(a) above, such payment will be made

3

within sixty (60) days after your Separation; however, if such sixty (60)-day period spans two calendar years, then the payment will be made in the second calendar year.

(iv)Equity Acceleration.  You will receive full vesting credit under your then-outstanding Equity Awards; provided, however, that in the event acceleration of the settlement or distribution date of an award would result in additional taxes and penalties under Section 409A of the Code, then the vesting of such award shall accelerate but settlement or distribution of award shares (or cash, if applicable) shall occur on the date(s) specified in the agreement governing the award.

6.Limitation on Payments.

(a)Scope of Limitation.  This Section 6 will apply only if the accounting firm serving as the Company’s independent public accountants immediately prior to a Change in Control (the “Accounting Firm”) determines that the after-tax value of all Payments (as defined below) to you under Section 5 of this Agreement, taking into account the effect of all federal, state and local income taxes, employment taxes and excise taxes applicable to you (including the excise tax under Section 4999 of the Code), will be greater after the application of this Section 6 than it was before the application of this Section 6.  If this Section 6 applies, it will supersede any contrary provision of this Agreement.  For purposes of this Section 6, the term “Company” will also include affiliated corporations to the extent determined by the Accounting Firm in accordance with Section 280G(d)(5) of the Code.

(b)Basic Rule.  In the event that the Accounting Firm determines that any payment or transfer by the Company to or for your benefit (a “Payment”) would be nondeductible by the Company for federal income tax purposes because of the provisions concerning “excess parachute payments” in Section 280G of the Code and pursuant to the regulations thereunder, then provided that Subsection (a) results in applicable of this Section 6, the aggregate present value of all Payments will be reduced (but not below zero) to the Reduced Amount.  For purposes of this Section 6, the “Reduced Amount” will be the amount, expressed as a present value, which maximizes the aggregate present value of the Payments without causing any Payment to be nondeductible by the Company because of Section 280G of the Code.

(c)Reduction of Payments.  If the Accounting Firm determines that any Payment would be nondeductible by the Company because of Section 280G of the Code, and if none of the Payments is subject to Section 409A of the Code, then the reduction will occur in the manner you elect in writing prior to the date of payment; provided, however, that if the manner elected by you pursuant to this sentence could in the opinion of the Company result in any of the Payments becoming subject to Section 409A of the Code, then the following sentence will instead apply.  If any Payment is subject to Section 409A of the Code, or if you fail to elect an order under the preceding sentence, then the reduction will occur in the following order: (i) cancellation of acceleration of vesting of any Equity Awards for which the exercise price (if any) exceeds the then-fair market value of the underlying Stock; (ii) reduction of cash payments (with such reduction being applied to the payments in the reverse order in which they would otherwise be made (that is, later payments will be reduced before earlier payments)); and (iii) cancellation of acceleration of vesting of Equity Awards not covered under (i) above; provided, however, that

4

in the event that acceleration of vesting of Equity Awards is to be cancelled, such acceleration of vesting will be cancelled in the reverse order of the date of grant of such Equity Awards (that is, later Equity Awards will be canceled before earlier Equity Awards).

(d)Fees of Accounting Firm and Required Data.  The Company will pay all fees, expenses and other costs associated with retaining the Accounting Firm for the purposes described in this Section 6.  You and the Company will provide to the Accounting Firm all data in the Company’s possession or under its control that the Accounting Firm reasonably requires for the purposes described in this Section 6.

7.Further Obligations to the Company.

(a)General.  You acknowledge your obligations under, and agree to comply with, all applicable laws and all Company policies in effect at all times and from time to time during your employment with the Company.  You further acknowledge and agree that such applicable laws or policies may relate to the general terms of your employment with the Company or to a specific component of your compensation. By way of example, such applicable laws or policies may include any Company recoupment or clawback policy, insider trading policy or code(s) of conduct or other policies adopted under, pursuant to or in light of, or requirements imposed by, the Sarbanes-Oxley Act of 2002 or the Dodd-Frank Wall Street Reform and Consumer Protection Act.

(b)Confidential Information.  You agree to execute such additional documents as may be necessary to protect the Company’s confidential and proprietary information, which such documents will supplement the Confidentiality Agreement (which such agreement will continue in full force and effect).

8.Employment Relationship.  Employment with the Company is for no specific period of time.  Your employment with the Company remains “at will,” meaning that either you or the Company may terminate your employment at any time and for any reason, with or without cause.  Any contrary representations that may have been made to you are superseded by this Agreement.  This is the full and complete agreement between you and the Company on this term.  Although your job duties, title, compensation and benefits, as well as the Company’s personnel policies and procedures, may change from time to time, the “at will” nature of your employment may only be changed in an express written agreement signed by you and a duly authorized officer of the Company (other than you).

9.Tax Matters.

(a)General.  All forms of compensation referred to in this Agreement are subject to reduction to reflect applicable withholding and payroll taxes and other deductions required by law. You are encouraged to obtain your own tax advice regarding your compensation from the Company.  You agree that the Company does not have a duty to design its compensation policies in a manner that minimizes your tax liabilities, and you will not make any claim against the Company or its Board related to tax liabilities arising from your compensation.

5

(b)Section 409A.  For purposes of Section 409A of the Code, each payment under Section 5 is hereby designated as a separate payment for purposes of Treasury Regulation 1.409A-2(b)(2).  If the Company determines that you are a “specified employee” under Section 409A(a)(2)(B)(i) of the Code at the time of your Separation, then (i) any payments under this Agreement, to the extent that they are not exempt from Section 409A of the Code (including by operation of the next following sentence) and otherwise subject to the taxes imposed under Section 409A(a)(1) of the Code (a “Deferred Payment”), will commence on the first business day following (A) the expiration of the six-month period measured from your Separation or (B) the date of your death and (ii) the installments that otherwise would have been paid prior to such date will be paid in a lump sum when such payments commence.  Notwithstanding the foregoing, any amount paid under this Agreement that either (1) satisfies the requirements of the “short-term deferral” rule set forth in Treasury Regulation 1.409A-1(b)(4); or (2) (A) qualifies as a payment made as a result of an involuntary separation from service pursuant to Treasury Regulation 1.409A-1(b)(9)(iii), and (B) does not exceed the Section 409A Limit will not constitute a Deferred Payment.  The provisions of this Agreement are intended to comply with, or be exempt from, the requirements of Section 409A of the Code so that none of the payments and benefits to be provided under this Agreement will be subject to the additional tax imposed under Section 409A of the Code, and any ambiguities herein will be interpreted to so comply or be exempt. You and the Company agree to work together in good faith to consider amendments to this Agreement and to take such reasonable actions as are necessary, appropriate or desirable to avoid imposition of any additional tax or income recognition prior to actual payment to you under Section 409A of the Code. In no event will the Company reimburse you for any taxes that may be imposed on you as result of Section 409A of the Code.

10.Interpretation, Amendment and Enforcement.  Upon the Effective Date, this Agreement will constitute the complete agreement between you and the Company, contain all of the terms of your employment with the Company and supersede and replace any prior agreements, policies, representations or understandings (whether written, oral, implied or otherwise) between you and the Company, including your participation in the Company’s Severance Benefits Policy.  This Agreement may not be amended or modified, except by an express written agreement signed by both you and a duly authorized officer of the Company.  The terms of this Agreement and the resolution of any disputes as to the meaning, effect, performance or validity of this Agreement or arising out of, related to, or in any way connected with, this Agreement, your employment with the Company or any other relationship between you and the Company (the “Disputes”) will be governed by California law, excluding laws relating to conflicts or choice of law.  You and the Company submit to the exclusive personal jurisdiction of the federal and state courts located in California in connection with any Dispute or any claim related to any Dispute.  By signing this Agreement, you acknowledge and agree that you will no longer be eligible for any benefits or payments provided for in any such prior agreement, except as otherwise expressly provided in this Agreement.

11.Successors and Assignment.

(a)Company’s Successors.  Any successor to the Company (whether direct or indirect and whether by purchase, lease, merger, consolidation, liquidation or otherwise) to all or substantially all of the Company’s business and/or assets will assume the obligations under

6

this Agreement and agree expressly to perform the obligations under this Agreement in the same manner and to the same extent as the Company would be required to perform such obligations in the absence of a succession.  For all purposes under this Agreement, the term “Company” shall include any such successor to the Company, or to the Company’s business and/or assets, that executes and delivers the assumption agreement described in this Section 11(a) or which becomes bound by the terms of this Agreement by operation of law.

(b)Employee’s Successors.  The terms of this Agreement and all of your rights hereunder will inure to the benefit of, and be enforceable by, your personal or legal representatives, executors, administrators, successors, heirs, distributees, devisees and legatees.  All of your obligations under this Agreement are personal to you and may not be transferred or assigned by you at any time.

12.Definitions.  The following terms have the meaning set forth below wherever they are used in this Agreement:

“Board” means the Company’s Board of Directors.

“Cause” means the occurrence of any one or more of the following: (a) your conviction by, or entry of a plea of “guilty” or nolo contendere in, a court of competent jurisdiction for any crime which constitutes a felony in the jurisdiction involved, (b) your commission of an act of theft or fraud, whether prior or subsequent to the date hereof, upon the Company, (c) your gross negligence in the scope of your services to the Company, (d) your breach of a material provision of any written agreement between you and the Company, (e) your continuing failure to perform assigned duties after receiving written notification of such failure from the Chief Executive Officer or (f) your failure to cooperate in good faith with a governmental or internal investigation of the Company or its directors, officers or employees, if the Company has requested your cooperation.

“Change in Control” means (a) any “person” (as such term is used in Sections 13(d) and 14(d) of the Exchange Act) becoming the “beneficial owner” (as defined in Rule 13d-3 of the Exchange Act), directly or indirectly, of securities of the Company representing more than fifty percent (50%) of the total voting power represented by the Company’s then-outstanding voting securities; (b) the consummation of the sale or disposition by the Company of all or substantially all of the Company’s assets; (c) the consummation of a merger or consolidation of the Company with or into any other entity, other than a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity or its parent) more than fifty percent (50%) of the total voting power represented by the voting securities of the Company or such surviving entity or its parent outstanding immediately after such merger or consolidation; or (d) individuals who are members of the Board (the “Incumbent Board”) cease for any reason to constitute at least a majority of the members of the Board over a period of twelve (12) months; provided, however, that if the appointment or election (or nomination for election) of any new Board member was approved or recommended by a majority vote of the members of the Incumbent Board then still in office,

7

such new member shall, for purposes of this Agreement, be considered as a member of the Incumbent Board.

A transaction will not constitute a Change in Control if its sole purpose is to change the state of the Company’s incorporation or to create a holding company that will be owned in substantially the same proportions by the persons who held the Company’s securities immediately before such transaction.  In addition, if a Change in Control constitutes a payment event with respect to any Equity Award which provides for a deferral of compensation and is subject to Section 409A of the Code, then notwithstanding anything to the contrary in this Agreement, the transaction with respect to such Equity Award must also constitute a “change in control event” as defined in Treasury Regulation 1.409A-3(i)(5) to the extent required by Section 409A of the Code.

“Code” means the Internal Revenue Code of 1986, as amended.

“Equity Awards” means (a) all shares of Stock; (b) all options and other rights to purchase shares of Stock; (c) all stock units, performance units or phantom shares whose value is measured by the value of shares of Stock; and (d) all stock appreciation rights whose value is measured by increases in the value of shares of Stock.

“Exchange Act” means the Securities Exchange Act of 1934, as amended.

“Involuntary Termination” means either (a) your Termination Without Cause (other than due to your death or Permanent Disability) or (b) your Resignation for Good Reason.

“Permanent Disability” means your total and permanent disability as defined in Section 22(e)(3) of the Code.

“Resignation for Good Reason” means a Separation as a result of your resignation within twelve (12) months after one of the following conditions initially has come into existence without your express written consent:

i.A material reduction of your duties, authority and responsibilities, relative to your duties, authority and responsibilities as in effect immediately prior to such reduction, or the assignment to you of such reduced duties, authority and responsibilities;

ii.A reduction in your base salary in effect immediately prior to such reduction;

iii.A material reduction in the kind or level of employee benefits to which you were entitled immediately prior to such reduction, with the result that your overall benefits package is materially reduced;

iv.A relocation to a facility or a location more than thirty-five miles from your then-present location that increases your one-way commute; or

8

Tom Tracey

Dear Tom:

Boingo Wireless, Inc. (the “Company”) is pleased to offer you continuing employment on the following terms, effective as of May 19, 2011 (the “Effective Date”).

1.Position.  Your title and position with the Company will be Senior Vice President of Operations, and you will report directly to the Chief Executive Officer.  This is a full-time position and your place of employment will be our headquarters in Los Angeles.  While you render services to the Company, you will not engage in any other employment, consulting or other business activity (whether full-time or part-time) that would create a conflict of interest with the Company.  By signing this Agreement, you confirm to the Company that you have no contractual commitments or other legal obligations that would prohibit you from performing your duties for the Company.

2.Cash Compensation.  Beginning as of January 1, 2011, your annual base salary will be $220,064 per year, payable in accordance with the Company’s standard payroll schedule.  This salary will be subject to adjustment pursuant to the Company’s employee compensation policies in effect from time to time. In addition, you will continue to be eligible to be considered for a cash-incentive bonus for each fiscal year of the Company.  The bonus (if any) will be awarded based on objective or subjective criteria established and approved by the Compensation Committee of the Board.  Your target bonus will be equal to 55% of your annual base salary, measured as of the last day of each fiscal year.  Any bonus for a fiscal year will be paid within 2½ months after the close of that fiscal year, but only if you are still employed by the Company at the time of payment.  The determinations of the Compensation Committee with respect to your bonus will be final and binding.

3.Employee Benefits.  As a regular employee of the Company, you will be eligible to participate in the Company’s standard employee benefits programs, as such are in effect from time to time.  In addition, you will be entitled to paid vacation in accordance with the Company’s vacation policy, as in effect from time to time.

4.Payments Upon Termination.  If your employment with the Company terminates other than as set forth in Section 5 below, then (a) all vesting will cease immediately with respect to your then-outstanding Equity Awards and (b) the only amounts payable to you by the Company will be (i) any unpaid base salary due for periods prior to the date of termination of your employment and (ii) any accrued but unused vacation through such termination date.  Such payments, if any, will be made promptly upon termination and within the period of time mandated by law.

5.Severance Benefits.

(a)General.  If you are subject to an Involuntary Termination, then you will be entitled to the benefits described in this Section 5.  However, you will not be entitled to any of the benefits described in this Section 5 unless you have (i) returned all Company property in your possession, (ii) resigned as a member of the Board and of the boards of directors of all of the Company’s subsidiaries, to the extent applicable, and (iii) executed a general release of all claims that you may have against the Company or persons affiliated with the Company, substantially in the form attached hereto as Exhibit A (the “Release”).  You must execute and return the release on or before the date specified by the Company in the Release (the “Release Deadline”).  The Release Deadline will in no event be later than fifty (50) days after your Separation.  If you fail to return the Release on or before the Release Deadline, or if you revoke the Release, then you will not be entitled to the benefits described in this Section 5.

Notwithstanding the foregoing, the Company may immediately discontinue all benefits or revoke any vesting acceleration described in this Section 5 (in addition to pursuing all other legal and equitable remedies) if you breach the Employee Inventions and Confidentiality Agreement or the Mutual Agreement to Arbitrate Claims between you and the Company that you previously signed (collectively, the “Confidentiality Agreement”), a copy of which is attached hereto as Exhibit B, the terms of Section 7 below or any other material agreement with the Company that by its terms continues in force following your Separation.

(b)Termination Not in Connection With Change in Control.  Subject to the requirements set forth in Section 5(a) above, if you experience an Involuntary Termination either prior to a Change in Control or more than twelve (12) months after a Change in Control, then you will be entitled to the following:

(i)Salary Continuation.  The Company will continue to pay your base salary for a period beginning on the day after your Separation and ending on the date nine (9) months after your Separation. Your base salary will be paid at the rate in effect at the time of your Separation and in accordance with the Company’s standard payroll procedures.  Subject to the Company’s having first received an effective Release pursuant to Section 5(a) above, the salary continuation payments will commence within sixty (60) days after your Separation and, once they commence, will include any unpaid amounts accrued from the date of your Separation.  However, if the sixty (60)-day period described in the preceding sentence spans two calendar years, then the payments will in any event begin in the second calendar year.

(ii)Additional Payment in Lieu of Health Benefit.  The Company will pay you a lump sum amount equal to the product of (A) nine (9) and (B) the monthly amount the Company was paying on behalf of you and your eligible dependents pursuant to the Company’s health insurance plans in which you or your dependents were participants as of the day of your Separation.  Subject to the Company’s having first received an effective Release pursuant to Section 5(a) above, such payment will be made within sixty (60) days after your Separation; however, if such sixty (60)-day period spans two calendar years, then the payment will be made in the second calendar year.

2

(iii)Equity Acceleration.  You will receive nine (9) months of vesting credit under your then-outstanding Equity Awards; provided, however, that in the event acceleration of the settlement or distribution date of an award would result in additional taxes and penalties under Section 409A of the Code, then the vesting of such award shall accelerate but settlement or distribution of award shares (or cash, if applicable) shall occur on the date(s) specified in the agreement governing the award.

(c)Termination in Connection With Change in Control.  Subject to the requirements set forth in Section 5(a) above, if you experience an Involuntary Termination within twelve (12) months following a Change in Control, then you will be entitled to the following:

(i)Salary Continuation.  The Company will continue to pay your base salary for a period beginning on the day after your Separation and ending on the date twelve (12) months after your Separation. Your base salary will be paid at the rate in effect at the time of your Separation and in accordance with the Company’s standard payroll procedures.  Subject to the Company’s having first received an effective Release pursuant to Section 5(a) above, the salary continuation payments will commence within sixty (60) days after your Separation and, once they commence, will include any unpaid amounts accrued from the date of your Separation.  However, if the sixty (60)-day period described in the preceding sentence spans two calendar years, then the payments will in any event begin in the second calendar year.

(ii)Target Bonus.  The Company will pay you a lump sum equal to your annual target bonus in the year of your Separation.  Subject to the Company’s having first received an effective Release pursuant to Section 5(a) above, such payment will be made within sixty (60) days after your Separation; however, if such sixty (60)-day period spans two calendar years, then the payment will be made in the second calendar year.

(iii)Additional Payment in Lieu of Health Benefit.  The Company will pay you a lump sum amount equal to the product of (A) twelve (12) and (B) the monthly amount the Company was paying on behalf of you and your eligible dependents pursuant to the Company’s health insurance plans in which you or your dependents were participants as of the day of your Separation.  Subject to the Company’s having first received an effective Release pursuant to Section 5(a) above, such payment will be made within sixty (60) days after your Separation; however, if such sixty (60)-day period spans two calendar years, then the payment will be made in the second calendar year.

(iv)Equity Acceleration.  You will receive full vesting credit under your then-outstanding Equity Awards; provided, however, that in the event acceleration of the settlement or distribution date of an award would result in additional taxes and penalties under Section 409A of the Code, then the vesting of such award shall accelerate but settlement or distribution of award shares (or cash, if applicable) shall occur on the date(s) specified in the agreement governing the award.

6.Limitation on Payments.

(a)Scope of Limitation.  This Section 6 will apply only if the accounting firm serving as the Company’s independent public accountants immediately prior to a Change in Control (the “Accounting Firm”) determines that the after-tax value of all Payments (as defined below) to you under Section 5 of this Agreement, taking into account the effect of all federal, state and local income taxes, employment taxes and excise taxes applicable to you (including the excise tax under Section 4999 of the Code), will be greater after the application of this Section 6 than it was before the application of this Section 6.  If this Section 6 applies, it will supersede any contrary provision of this Agreement.  For purposes of this Section 6, the term “Company” will also include affiliated corporations to the extent determined by the Accounting Firm in accordance with Section 280G(d)(5) of the Code.

(b)Basic Rule.  In the event that the Accounting Firm determines that any payment or transfer by the Company to or for your benefit (a “Payment”) would be nondeductible by the Company for federal income tax purposes because of the provisions concerning “excess parachute payments” in Section 280G of the Code and pursuant to the regulations thereunder, then provided that Subsection (a) results in applicable of this Section 6, the aggregate present value of all Payments will be reduced (but not below zero) to the Reduced Amount.  For purposes of this Section 6, the “Reduced Amount” will be the amount, expressed as a present value, which maximizes the aggregate present value of the Payments without causing any Payment to be nondeductible by the Company because of Section 280G of the Code.

(c)Reduction of Payments.  If the Accounting Firm determines that any Payment would be nondeductible by the Company because of Section 280G of the Code, and if none of the Payments is subject to Section 409A of the Code, then the reduction will occur in the manner you elect in writing prior to the date of payment; provided, however, that if the manner elected by you pursuant to this sentence could in the opinion of the Company result in any of the Payments becoming subject to Section 409A of the Code, then the following sentence will instead apply.  If any Payment is subject to Section 409A of the Code, or if you fail to elect an order under the preceding sentence, then the reduction will occur in the following order: (i) cancellation of acceleration of vesting of any Equity Awards for which the exercise price (if any) exceeds the then-fair market value of the underlying Stock; (ii) reduction of cash payments (with such reduction being applied to the payments in the reverse order in which they would otherwise be made (that is, later payments will be reduced before earlier payments)); and (iii) cancellation of acceleration of vesting of Equity Awards not covered under (i) above; provided, however, that in the event that acceleration of vesting of Equity Awards is to be cancelled, such acceleration of vesting will be cancelled in the reverse order of the date of grant of such Equity Awards (that is, later Equity Awards will be canceled before earlier Equity Awards).

(d)Fees of Accounting Firm and Required Data.  The Company will pay all fees, expenses and other costs associated with retaining the Accounting Firm for the purposes described in this Section 6.  You and the Company will provide to the Accounting Firm all data in the Company’s possession or under its control that the Accounting Firm reasonably requires for the purposes described in this Section 6.

4

7.Further Obligations to the Company.

(a)General.  You acknowledge your obligations under, and agree to comply with, all applicable laws and all Company policies in effect at all times and from time to time during your employment with the Company.  You further acknowledge and agree that such applicable laws or policies may relate to the general terms of your employment with the Company or to a specific component of your compensation. By way of example, such applicable laws or policies may include any Company recoupment or clawback policy, insider trading policy or code(s) of conduct or other policies adopted under, pursuant to or in light of, or requirements imposed by, the Sarbanes-Oxley Act of 2002 or the Dodd-Frank Wall Street Reform and Consumer Protection Act.

(b)Confidential Information.  You agree to execute such additional documents as may be necessary to protect the Company’s confidential and proprietary information, which such documents will supplement the Confidentiality Agreement (which such agreement will continue in full force and effect).

8.Employment Relationship.  Employment with the Company is for no specific period of time.  Your employment with the Company remains “at will,” meaning that either you or the Company may terminate your employment at any time and for any reason, with or without cause.  Any contrary representations that may have been made to you are superseded by this Agreement.  This is the full and complete agreement between you and the Company on this term.  Although your job duties, title, compensation and benefits, as well as the Company’s personnel policies and procedures, may change from time to time, the “at will” nature of your employment may only be changed in an express written agreement signed by you and a duly authorized officer of the Company (other than you).

9.Tax Matters.

(a)General.  All forms of compensation referred to in this Agreement are subject to reduction to reflect applicable withholding and payroll taxes and other deductions required by law. You are encouraged to obtain your own tax advice regarding your compensation from the Company.  You agree that the Company does not have a duty to design its compensation policies in a manner that minimizes your tax liabilities, and you will not make any claim against the Company or its Board related to tax liabilities arising from your compensation.

(b)Section 409A.  For purposes of Section 409A of the Code, each payment under Section 5 is hereby designated as a separate payment for purposes of Treasury Regulation 1.409A-2(b)(2).  If the Company determines that you are a “specified employee” under Section 409A(a)(2)(B)(i) of the Code at the time of your Separation, then (i) any payments under this Agreement, to the extent that they are not exempt from Section 409A of the Code (including by operation of the next following sentence) and otherwise subject to the taxes imposed under Section 409A(a)(1) of the Code (a “Deferred Payment”), will commence on the first business day following (A) the expiration of the six-month period measured from your Separation or (B) the date of your death and (ii) the installments that otherwise would have been paid prior to such date will be paid in a lump sum when such payments commence.  Notwithstanding the

5

foregoing, any amount paid under this Agreement that either (1) satisfies the requirements of the “short-term deferral” rule set forth in Treasury Regulation 1.409A-1(b)(4); or (2) (A) qualifies as a payment made as a result of an involuntary separation from service pursuant to Treasury Regulation 1.409A-1(b)(9)(iii), and (B) does not exceed the Section 409A Limit will not constitute a Deferred Payment.  The provisions of this Agreement are intended to comply with, or be exempt from, the requirements of Section 409A of the Code so that none of the payments and benefits to be provided under this Agreement will be subject to the additional tax imposed under Section 409A of the Code, and any ambiguities herein will be interpreted to so comply or be exempt. You and the Company agree to work together in good faith to consider amendments to this Agreement and to take such reasonable actions as are necessary, appropriate or desirable to avoid imposition of any additional tax or income recognition prior to actual payment to you under Section 409A of the Code. In no event will the Company reimburse you for any taxes that may be imposed on you as result of Section 409A of the Code.

10.Interpretation, Amendment and Enforcement.  Upon the Effective Date, this Agreement will constitute the complete agreement between you and the Company, contain all of the terms of your employment with the Company and supersede and replace any prior agreements, policies, representations or understandings (whether written, oral, implied or otherwise) between you and the Company, including your participation in the Company’s Severance Benefits Policy.  This Agreement may not be amended or modified, except by an express written agreement signed by both you and a duly authorized officer of the Company.  The terms of this Agreement and the resolution of any disputes as to the meaning, effect, performance or validity of this Agreement or arising out of, related to, or in any way connected with, this Agreement, your employment with the Company or any other relationship between you and the Company (the “Disputes”) will be governed by California law, excluding laws relating to conflicts or choice of law.  You and the Company submit to the exclusive personal jurisdiction of the federal and state courts located in California in connection with any Dispute or any claim related to any Dispute.  By signing this Agreement, you acknowledge and agree that you will no longer be eligible for any benefits or payments provided for in any such prior agreement, except as otherwise expressly provided in this Agreement.

11.Successors and Assignment.

(a)Company’s Successors.  Any successor to the Company (whether direct or indirect and whether by purchase, lease, merger, consolidation, liquidation or otherwise) to all or substantially all of the Company’s business and/or assets will assume the obligations under this Agreement and agree expressly to perform the obligations under this Agreement in the same manner and to the same extent as the Company would be required to perform such obligations in the absence of a succession.  For all purposes under this Agreement, the term “Company” shall include any such successor to the Company, or to the Company’s business and/or assets, that executes and delivers the assumption agreement described in this Section 11(a) or which becomes bound by the terms of this Agreement by operation of law.

(b)Employee’s Successors.  The terms of this Agreement and all of your rights hereunder will inure to the benefit of, and be enforceable by, your personal or legal representatives, executors, administrators, successors, heirs, distributees, devisees and legatees.

6

All of your obligations under this Agreement are personal to you and may not be transferred or assigned by you at any time.

“Board” means the Company’s Board of Directors.

“Cause” means the occurrence of any one or more of the following: (a) your conviction by, or entry of a plea of “guilty” or nolo contendere in, a court of competent jurisdiction for any crime which constitutes a felony in the jurisdiction involved, (b) your commission of an act of theft or fraud, whether prior or subsequent to the date hereof, upon the Company, (c) your gross negligence in the scope of your services to the Company, (d) your breach of a material provision of any written agreement between you and the Company, (e) your continuing failure to perform assigned duties after receiving written notification of such failure from the Chief Executive Officer or (f) your failure to cooperate in good faith with a governmental or internal investigation of the Company or its directors, officers or employees, if the Company has requested your cooperation.

A transaction will not constitute a Change in Control if its sole purpose is to change the state of the Company’s incorporation or to create a holding company that will be owned in substantially the same proportions by the persons who held the Company’s securities immediately before such transaction.  In addition, if a Change in Control constitutes a payment event with respect to any Equity Award which provides for a deferral of compensation and is subject to Section 409A of the Code, then notwithstanding anything to the contrary in this Agreement, the transaction with respect to such Equity Award must also constitute a “change in control event” as defined in Treasury Regulation 1.409A-3(i)(5) to the extent required by Section 409A of the Code.

(c)Termination in Connection With Change in Control.  Subject to the requirements set forth in Section 5(a) above, if you experience an Involuntary Termination within twelve (12) months following a Change in Control, then you will be entitled to the following:

(i)Salary Continuation.  The Company will continue to pay your base salary for a period beginning on the day after your Separation and ending on the date twelve (12) months after your Separation. Your base salary will be paid at the rate in effect at the time of your Separation and in accordance with the Company’s standard payroll procedures.  Subject to the Company’s having first received an effective Release pursuant to Section 5(a) above, the salary continuation payments will commence within sixty (60) days after your Separation and, once they commence, will include any unpaid amounts accrued from the date of your Separation.  However, if the sixty (60)-day period described in the preceding sentence spans two calendar years, then the payments will in any event begin in the second calendar year.

(ii)Target Bonus.  The Company will pay you a lump sum equal to your annual target bonus in the year of your Separation.  Subject to the Company’s having first received an effective Release pursuant to Section 5(a) above, such payment will be made within sixty (60) days after your Separation; however, if such sixty (60)-day period spans two calendar years, then the payment will be made in the second calendar year.

(iii)Additional Payment in Lieu of Health Benefit.  The Company will pay you a lump sum amount equal to the product of (A) twelve (12) and (B) the monthly amount the Company was paying on behalf of you and your eligible dependents pursuant to the Company’s health insurance plans in which you or your dependents were participants as of the day of your Separation.  Subject to the Company’s having first received an effective Release pursuant to Section 5(a) above, such payment will be made

3

within sixty (60) days after your Separation; however, if such sixty (60)-day period spans two calendar years, then the payment will be made in the second calendar year.

(iv)Equity Acceleration.  You will receive full vesting credit under your then-outstanding Equity Awards; provided, however, that in the event acceleration of the settlement or distribution date of an award would result in additional taxes and penalties under Section 409A of the Code, then the vesting of such award shall accelerate but settlement or distribution of award shares (or cash, if applicable) shall occur on the date(s) specified in the agreement governing the award.

6.Limitation on Payments.

(a)Scope of Limitation.  This Section 6 will apply only if the accounting firm serving as the Company’s independent public accountants immediately prior to a Change in Control (the “Accounting Firm”) determines that the after-tax value of all Payments (as defined below) to you under Section 5 of this Agreement, taking into account the effect of all federal, state and local income taxes, employment taxes and excise taxes applicable to you (including the excise tax under Section 4999 of the Code), will be greater after the application of this Section 6 than it was before the application of this Section 6.  If this Section 6 applies, it will supersede any contrary provision of this Agreement.  For purposes of this Section 6, the term “Company” will also include affiliated corporations to the extent determined by the Accounting Firm in accordance with Section 280G(d)(5) of the Code.

(b)Basic Rule.  In the event that the Accounting Firm determines that any payment or transfer by the Company to or for your benefit (a “Payment”) would be nondeductible by the Company for federal income tax purposes because of the provisions concerning “excess parachute payments” in Section 280G of the Code and pursuant to the regulations thereunder, then provided that Subsection (a) results in applicable of this Section 6, the aggregate present value of all Payments will be reduced (but not below zero) to the Reduced Amount.  For purposes of this Section 6, the “Reduced Amount” will be the amount, expressed as a present value, which maximizes the aggregate present value of the Payments without causing any Payment to be nondeductible by the Company because of Section 280G of the Code.

(c)Reduction of Payments.  If the Accounting Firm determines that any Payment would be nondeductible by the Company because of Section 280G of the Code, and if none of the Payments is subject to Section 409A of the Code, then the reduction will occur in the manner you elect in writing prior to the date of payment; provided, however, that if the manner elected by you pursuant to this sentence could in the opinion of the Company result in any of the Payments becoming subject to Section 409A of the Code, then the following sentence will instead apply.  If any Payment is subject to Section 409A of the Code, or if you fail to elect an order under the preceding sentence, then the reduction will occur in the following order: (i) cancellation of acceleration of vesting of any Equity Awards for which the exercise price (if any) exceeds the then-fair market value of the underlying Stock; (ii) reduction of cash payments (with such reduction being applied to the payments in the reverse order in which they would otherwise be made (that is, later payments will be reduced before earlier payments)); and (iii) cancellation of acceleration of vesting of Equity Awards not covered under (i) above; provided, however, that

4

in the event that acceleration of vesting of Equity Awards is to be cancelled, such acceleration of vesting will be cancelled in the reverse order of the date of grant of such Equity Awards (that is, later Equity Awards will be canceled before earlier Equity Awards).

(d)Fees of Accounting Firm and Required Data.  The Company will pay all fees, expenses and other costs associated with retaining the Accounting Firm for the purposes described in this Section 6.  You and the Company will provide to the Accounting Firm all data in the Company’s possession or under its control that the Accounting Firm reasonably requires for the purposes described in this Section 6.

7.Further Obligations to the Company.

(a)General.  You acknowledge your obligations under, and agree to comply with, all applicable laws and all Company policies in effect at all times and from time to time during your employment with the Company.  You further acknowledge and agree that such applicable laws or policies may relate to the general terms of your employment with the Company or to a specific component of your compensation. By way of example, such applicable laws or policies may include any Company recoupment or clawback policy, insider trading policy or code(s) of conduct or other policies adopted under, pursuant to or in light of, or requirements imposed by, the Sarbanes-Oxley Act of 2002 or the Dodd-Frank Wall Street Reform and Consumer Protection Act.

(b)Confidential Information.  You agree to execute such additional documents as may be necessary to protect the Company’s confidential and proprietary information, which such documents will supplement the Confidentiality Agreement (which such agreement will continue in full force and effect).

8.Employment Relationship.  Employment with the Company is for no specific period of time.  Your employment with the Company remains “at will,” meaning that either you or the Company may terminate your employment at any time and for any reason, with or without cause.  Any contrary representations that may have been made to you are superseded by this Agreement.  This is the full and complete agreement between you and the Company on this term.  Although your job duties, title, compensation and benefits, as well as the Company’s personnel policies and procedures, may change from time to time, the “at will” nature of your employment may only be changed in an express written agreement signed by you and a duly authorized officer of the Company (other than you).

9.Tax Matters.

(a)General.  All forms of compensation referred to in this Agreement are subject to reduction to reflect applicable withholding and payroll taxes and other deductions required by law. You are encouraged to obtain your own tax advice regarding your compensation from the Company.  You agree that the Company does not have a duty to design its compensation policies in a manner that minimizes your tax liabilities, and you will not make any claim against the Company or its Board related to tax liabilities arising from your compensation.

5

(b)Section 409A.  For purposes of Section 409A of the Code, each payment under Section 5 is hereby designated as a separate payment for purposes of Treasury Regulation 1.409A-2(b)(2).  If the Company determines that you are a “specified employee” under Section 409A(a)(2)(B)(i) of the Code at the time of your Separation, then (i) any payments under this Agreement, to the extent that they are not exempt from Section 409A of the Code (including by operation of the next following sentence) and otherwise subject to the taxes imposed under Section 409A(a)(1) of the Code (a “Deferred Payment”), will commence on the first business day following (A) the expiration of the six-month period measured from your Separation or (B) the date of your death and (ii) the installments that otherwise would have been paid prior to such date will be paid in a lump sum when such payments commence.  Notwithstanding the foregoing, any amount paid under this Agreement that either (1) satisfies the requirements of the “short-term deferral” rule set forth in Treasury Regulation 1.409A-1(b)(4); or (2) (A) qualifies as a payment made as a result of an involuntary separation from service pursuant to Treasury Regulation 1.409A-1(b)(9)(iii), and (B) does not exceed the Section 409A Limit will not constitute a Deferred Payment.  The provisions of this Agreement are intended to comply with, or be exempt from, the requirements of Section 409A of the Code so that none of the payments and benefits to be provided under this Agreement will be subject to the additional tax imposed under Section 409A of the Code, and any ambiguities herein will be interpreted to so comply or be exempt. You and the Company agree to work together in good faith to consider amendments to this Agreement and to take such reasonable actions as are necessary, appropriate or desirable to avoid imposition of any additional tax or income recognition prior to actual payment to you under Section 409A of the Code. In no event will the Company reimburse you for any taxes that may be imposed on you as result of Section 409A of the Code.

10.Interpretation, Amendment and Enforcement.  Upon the Effective Date, this Agreement will constitute the complete agreement between you and the Company, contain all of the terms of your employment with the Company and supersede and replace any prior agreements, policies, representations or understandings (whether written, oral, implied or otherwise) between you and the Company, including your participation in the Company’s Severance Benefits Policy.  This Agreement may not be amended or modified, except by an express written agreement signed by both you and a duly authorized officer of the Company.  The terms of this Agreement and the resolution of any disputes as to the meaning, effect, performance or validity of this Agreement or arising out of, related to, or in any way connected with, this Agreement, your employment with the Company or any other relationship between you and the Company (the “Disputes”) will be governed by California law, excluding laws relating to conflicts or choice of law.  You and the Company submit to the exclusive personal jurisdiction of the federal and state courts located in California in connection with any Dispute or any claim related to any Dispute.  By signing this Agreement, you acknowledge and agree that you will no longer be eligible for any benefits or payments provided for in any such prior agreement, except as otherwise expressly provided in this Agreement.

11.Successors and Assignment.

(a)Company’s Successors.  Any successor to the Company (whether direct or indirect and whether by purchase, lease, merger, consolidation, liquidation or otherwise) to all or substantially all of the Company’s business and/or assets will assume the obligations under

6

this Agreement and agree expressly to perform the obligations under this Agreement in the same manner and to the same extent as the Company would be required to perform such obligations in the absence of a succession.  For all purposes under this Agreement, the term “Company” shall include any such successor to the Company, or to the Company’s business and/or assets, that executes and delivers the assumption agreement described in this Section 11(a) or which becomes bound by the terms of this Agreement by operation of law.

(b)Employee’s Successors.  The terms of this Agreement and all of your rights hereunder will inure to the benefit of, and be enforceable by, your personal or legal representatives, executors, administrators, successors, heirs, distributees, devisees and legatees.  All of your obligations under this Agreement are personal to you and may not be transferred or assigned by you at any time.

12.Definitions.  The following terms have the meaning set forth below wherever they are used in this Agreement:

“Board” means the Company’s Board of Directors.

“Cause” means the occurrence of any one or more of the following: (a) your conviction by, or entry of a plea of “guilty” or nolo contendere in, a court of competent jurisdiction for any crime which constitutes a felony in the jurisdiction involved, (b) your commission of an act of theft or fraud, whether prior or subsequent to the date hereof, upon the Company, (c) your gross negligence in the scope of your services to the Company, (d) your breach of a material provision of any written agreement between you and the Company, (e) your continuing failure to perform assigned duties after receiving written notification of such failure from the Chief Executive Officer or (f) your failure to cooperate in good faith with a governmental or internal investigation of the Company or its directors, officers or employees, if the Company has requested your cooperation.

“Change in Control” means (a) any “person” (as such term is used in Sections 13(d) and 14(d) of the Exchange Act) becoming the “beneficial owner” (as defined in Rule 13d-3 of the Exchange Act), directly or indirectly, of securities of the Company representing more than fifty percent (50%) of the total voting power represented by the Company’s then-outstanding voting securities; (b) the consummation of the sale or disposition by the Company of all or substantially all of the Company’s assets; (c) the consummation of a merger or consolidation of the Company with or into any other entity, other than a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity or its parent) more than fifty percent (50%) of the total voting power represented by the voting securities of the Company or such surviving entity or its parent outstanding immediately after such merger or consolidation; or (d) individuals who are members of the Board (the “Incumbent Board”) cease for any reason to constitute at least a majority of the members of the Board over a period of twelve (12) months; provided, however, that if the appointment or election (or nomination for election) of any new Board member was approved or recommended by a majority vote of the members of the Incumbent Board then still in office,

7

such new member shall, for purposes of this Agreement, be considered as a member of the Incumbent Board.

A transaction will not constitute a Change in Control if its sole purpose is to change the state of the Company’s incorporation or to create a holding company that will be owned in substantially the same proportions by the persons who held the Company’s securities immediately before such transaction.  In addition, if a Change in Control constitutes a payment event with respect to any Equity Award which provides for a deferral of compensation and is subject to Section 409A of the Code, then notwithstanding anything to the contrary in this Agreement, the transaction with respect to such Equity Award must also constitute a “change in control event” as defined in Treasury Regulation 1.409A-3(i)(5) to the extent required by Section 409A of the Code.

“Code” means the Internal Revenue Code of 1986, as amended.

“Equity Awards” means (a) all shares of Stock; (b) all options and other rights to purchase shares of Stock; (c) all stock units, performance units or phantom shares whose value is measured by the value of shares of Stock; and (d) all stock appreciation rights whose value is measured by increases in the value of shares of Stock.

“Exchange Act” means the Securities Exchange Act of 1934, as amended.

“Involuntary Termination” means either (a) your Termination Without Cause (other than due to your death or Permanent Disability) or (b) your Resignation for Good Reason.

“Permanent Disability” means your total and permanent disability as defined in Section 22(e)(3) of the Code.

“Resignation for Good Reason” means a Separation as a result of your resignation within twelve (12) months after one of the following conditions initially has come into existence without your express written consent:

i.A material reduction of your duties, authority and responsibilities, relative to your duties, authority and responsibilities as in effect immediately prior to such reduction, or the assignment to you of such reduced duties, authority and responsibilities;

ii.A reduction in your base salary in effect immediately prior to such reduction;

iii.A material reduction in the kind or level of employee benefits to which you were entitled immediately prior to such reduction, with the result that your overall benefits package is materially reduced;

iv.A relocation to a facility or a location more than thirty-five miles from your then-present location that increases your one-way commute; or

8

v.The Company’s breach of this Agreement, including its failure to obtain the assumption of this Agreement by any successor (whether direct or indirect and whether by purchase, merger, consolidation, liquidation or otherwise) to all or substantially all of the Company’s business and/or assets.

A Resignation for Good Reason will not be deemed to have occurred unless you give the Company written notice of the condition within ninety (90) days after the condition initially comes into existence and the Company fails to remedy the condition within thirty (30) days after receiving your written notice.

“Section 409A Limit” means the lesser of two times: (i) your annualized compensation based upon the annual rate of pay paid to you during the taxable year preceding your taxable year in which your termination of employment occurs, as determined under, and with such adjustments as are set forth in, Treasury Regulation 1.409A-1(b)(9)(iii)(A)(1) and any guidance issued with respect thereto or (ii) the maximum amount that may be taken into account under a qualified plan pursuant to Section 401(a)(17) of the Code for the year in which your employment is terminated.

“Separation” means a “separation from service,” as defined in the regulations under Section 409A of the Code.

Summary of significant accounting policies

Basis of presentation and consolidation

• Basis of presentation and consolidation

        Our consolidated financial statements for the years ended December 31, 2013, 2012 and 2011 have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP").

        The accompanying consolidated financial statements include our accounts and our majority owned subsidiaries. We consolidate our 70% ownership of Concourse Communications Detroit, LLC, our 70% ownership of Chicago Concourse Development Group, LLC and our 75% ownership of Boingo Holding Participacoes Ltda. in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 810, Consolidation. Other parties' interests in consolidated entities are reported as non-controlling interests. All intercompany balances and transactions have been eliminated in consolidation.

        During the year ended December 31, 2013, the Company recorded certain out-of-period adjustments that decreased net loss attributable to common stockholders by $217. The impact of these out-of-period adjustments is not considered material, individually and in the aggregate, to any of the current or prior annual periods.

        The consolidated balance sheet as of December 31, 2012 has been revised to properly classify $2,066 of unbilled receivables from other non-current assets to accounts receivable, net. The revision has also been reflected in Note 5 to the consolidated financial statements. The impact of this revision is not material to the prior year consolidated balance sheet.

Use of estimates

• Use of estimates

        The preparation of accompanying consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the dates of the accompanying consolidated financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Assets and liabilities which are subject to significant judgment and the use of estimates include the allowance for doubtful accounts, recoverability of goodwill and long-lived assets, valuation allowances with respect to deferred tax assets, uncertain tax positions, useful lives associated with property and equipment, valuation and useful lives of intangible assets, valuation of contingent consideration, and the valuation and assumptions underlying stock-based compensation and other equity instruments. On an ongoing basis, we evaluate our estimates compared to historical experience and trends, which form the basis for making judgments about the carrying value of assets and liabilities. In addition, prior to our IPO, we regularly engaged the assistance of valuation specialists in determining fair value measurements in connection with stock-based compensation and other equity instruments.

Concentrations of credit risk

• Concentrations of credit risk

        Financial instruments that potentially subject us to significant concentrations of credit risk consist primarily of cash and cash equivalents, restricted cash, marketable securities and accounts receivable. We maintain our cash and cash equivalents, restricted cash and marketable securities with institutions with high credit ratings. We extend credit based upon the evaluation of the customer's financial condition and generally collateral is not required. We maintain an allowance for doubtful accounts based upon expected collectability of accounts receivable. We primarily estimate our allowance for doubtful accounts based on a specific review of significant outstanding accounts receivable. For the year ended December 31, 2013 two groups of affiliated entities each accounted for 14% of total revenue. For the year ended December 31, 2012, those same two groups of affiliated entities accounted for 17% and 15% of total revenue, respectively. For the year ended December 31, 2011, one group of affiliated entities accounted for 18% of total revenue. At December 31, 2013, one group of affiliated entities accounted for 12% of the total accounts receivable. At December 31, 2012, three groups of affiliated entities accounted for 26%, 16% and 10% of the total accounts receivable, respectively.

Cash and cash equivalents

• Cash and cash equivalents

        Cash and cash equivalents include highly liquid investments that are readily convertible into known amounts of cash with original maturities of three months or less when acquired. At December 31, 2013, cash equivalents consisted of money market funds. At December 31, 2012, cash equivalents consisted of money market funds and marketable securities with original maturities of three months or less.

Marketable securities

• Marketable securities

        Our marketable securities consist of available-for-sale securities with original maturities exceeding three months. In accordance with FASB ASC 320, Investments—Debt and Equity Securities, we have classified securities, which have readily determinable fair values and are highly liquid, as short-term because such securities are expected to be realized within a one- year period. At December 31, 2013 and 2012, we had $32,962 and $41,558, respectively, in short-term marketable securities and no long-term marketable securities.

        Marketable securities are reported at fair value with the related unrealized gains and losses reported as other comprehensive income (loss) until realized or until a determination is made that an other-than-temporary decline in market value has occurred. No significant unrealized gains and losses have been reported during the years presented. Factors considered by us in assessing whether an other-than-temporary impairment has occurred include the nature of the investment, whether the decline in fair value is attributable to specific adverse conditions affecting the investment, the financial condition of the investee, the severity and the duration of the impairment and whether we have the ability to hold the investment to maturity. When it is determined that an other-than-temporary impairment has occurred, the investment is written down to its market value at the end of the period in which it is determined that an other-than-temporary decline has occurred. The cost of marketable securities sold is based upon the specific identification method. Any realized gains or losses on the sale of investments are reflected as a component of interest and other income (expense), net.

        For the years ended December 31, 2013, 2012 and 2011, we had no significant realized or unrealized gains or losses from investments in marketable securities classified as available-for-sale.

Restricted cash

• Restricted cash

        Restricted cash consists of letters of credit with our landlords, municipalities or venues for which we have operating agreements. Letters of credit are supported by cash deposits made by us and invested into bank certificates of deposit. At December 31, 2013 and 2012, we had $545 and $30 classified as short-term restricted cash, respectively. At December 31, 2013 and 2012, we had no restricted cash classified as long-term.

Fair value of financial instruments

• Fair value of financial instruments

        Fair value is defined as the price that would be received from selling an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, we consider the principal or most advantageous market in which it would transact, and we consider assumptions that market participants would use when pricing the asset or liability.

        The accounting guidance for fair value measurement also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard establishes a fair value hierarchy based on the level of independent, objective evidence surrounding the inputs used to measure fair value. A financial instrument's categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The fair value hierarchy is as follows:

• •

  Level 1—Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.

  •

  Level 2—Quoted prices for identical assets and liabilities in markets that are not active, quoted prices for similar assets and liabilities in active markets or financial instruments for which significant inputs are observable, either directly or indirectly.

  •

  Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

        The carrying amount reflected in the accompanying consolidated balance sheets for cash and cash equivalents, restricted cash, marketable securities, accounts receivable, prepaid expenses and other current assets, accounts payable, accrued expenses and other liabilities approximates fair value due to the short-term nature of these financial instruments.

Business combinations

• Business combinations

        The results of businesses acquired in a business combination are included in the Company's consolidated financial statements from the date of the acquisition. Purchase accounting results in assets and liabilities of an acquired business being recorded at their estimated fair values on the acquisition date. Any excess consideration over the fair value of assets acquired and liabilities assumed is recognized as goodwill.

        The Company performs valuations of assets acquired and liabilities assumed from a business acquisition and will allocate the purchase price to its respective net tangible and intangible assets. Determining the fair value of assets acquired and liabilities assumed requires management to use significant judgment and estimates including the selection of valuation methodologies, estimates of future revenues and cash flows, discount rates, royalty rates and selection of comparable companies. The Company engages the assistance of valuation specialists in concluding on fair value measurements in connection with fair values of assets and liabilities assumed in a business combination.

        Transaction costs associated with business combinations are expensed as incurred, and are included in general and administrative expenses in the consolidated statements of operations. Transaction costs were $354 and $50 for the years ended December 31, 2013 and 2012, respectively. There were no transaction costs for the year ended December 31, 2011.

Property and equipment

• Property and equipment

        Property and equipment are generally stated at historical cost, less accumulated depreciation and amortization. The Company's cost basis includes property and equipment acquired in business combinations that were initially recorded at fair value as of the date of acquisition. Maintenance and repairs are charged to expense as incurred and the cost of additions and betterments that increase the useful lives of the assets are capitalized. Depreciation and amortization is computed over the estimated useful lives of the related asset type using the straight-line method.

        The estimated useful lives for property and equipment are as follows:

Computer equipment	2 to 5 years
Software	2 to 5 years
Office equipment	3 to 5 years
Leasehold improvements	The shorter of the estimated useful life or the remaining term of the agreements, generally ranging from 2 to 15 years

        Leasehold improvements are principally comprised of network equipment located at various managed and operated locations, primarily airports, under exclusive, long-term, non-cancelable contracts to provide wireless communication network access.

Equipment and software under capital lease

• Equipment and software under capital lease

        We lease certain data communications equipment, other equipment and software under capital lease agreements. The assets and liabilities under capital lease are recorded at the lesser of the present value of aggregate future minimum lease payments, including estimated bargain purchase options, or the fair value of the asset under lease. Assets under capital lease are depreciated using the straight-line method over the shorter of the estimated useful lives of the assets or the term of the lease agreements.

Software development costs

• Software development costs

        We capitalize costs associated with software developed or obtained for internal use when the preliminary project stage is completed and it is determined that the software will provide significantly enhanced capabilities and modifications. These capitalized costs are included in property and equipment and include external direct cost of services procured in developing or obtaining internal-use software and personnel and related expenses for employees who are directly associated with, and who devote time to internal-use software projects. Capitalization of these costs ceases once the project is substantially complete and the software is ready for its intended use. Once the software is ready for its intended use, the costs are amortized over the useful life of the software. Post-configuration training and maintenance costs are expensed as incurred.

Long-lived assets

• Long-lived assets

        Intangible assets consist of acquired venue contracts, technology, advertiser relationships, non-compete agreements and patents and trademarks. We record intangible assets at fair value as of the date of acquisition and amortize these finite-lived assets over the shorter of the contractual life or the estimated useful life on a straight-line basis. We estimate the useful lives of acquired intangible assets based on factors that include the planned use of each acquired intangible asset, the expected pattern of future cash flows to be derived from each acquired intangible asset and contractual periods specified in the related agreements. As such, we account for each of the venue contracts individually. We include amortization of acquired intangibles in amortization of intangible assets in the accompanying consolidated statements of operations.

        We perform an impairment review of long-lived assets held and used whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Factors we consider important that could trigger an impairment review include, but are not limited to: significant under-performance relative to projected future operating results, significant changes in the manner of our use of the acquired assets or our overall business and product strategies and significant industry or economic trends. When we determine that the carrying value of a long-lived asset may not be recoverable based upon the existence of one or more of these indicators, we determine the recoverability by comparing the carrying amount of the asset to net future undiscounted cash flows that the asset is expected to generate or other indices of fair value. We would then recognize an impairment charge equal to the amount by which the carrying amount exceeds the fair market value of the asset.

Goodwill

• Goodwill

        Goodwill represents the excess of the purchase price over the fair value of net assets acquired in connection with the acquisition of Concourse Communication Group, LLC in June 2006, Cloud 9 Wireless, Inc. in August 2012, Endeka Group, Inc. in February 2013, and Electronic Media Systems, Inc. and Advanced Wireless Group, LLC in October 2013.

        We test goodwill for impairment in accordance with guidance provided by FASB ASC 350, Intangibles—Goodwill and Other ("ASC 350"). Goodwill is tested for impairment at least annually at the reporting unit level or whenever events or changes in circumstances indicate that goodwill might be impaired. Events or changes in circumstances which could trigger an impairment review include a significant adverse change in legal factors or in the business climate, an adverse action or assessment by a regulator, unanticipated competition, a loss of key personnel, significant changes in the manner of our use of the acquired assets or the strategy for our overall business, significant negative industry or economic trends, or significant underperformance relative to expected historical or projected future results of operations. We perform our impairment test annually as of December 31^st.

        Entities have the option to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test described in FASB ASC 350. If, after assessing qualitative factors, an entity determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then performing the two-step impairment test is unnecessary. If deemed necessary, a two-step test is used to identify the potential impairment and to measure the amount of goodwill impairment, if any. The first step is to compare the fair value of the reporting unit with its carrying amount, including goodwill. If the fair value of the reporting unit exceeds its carrying amount, goodwill is considered not impaired; otherwise, there is an indication that goodwill may be impaired and the amount of the loss, if any, is measured by performing step two. Under step two, the impairment loss, if any, is measured by comparing the implied fair value of the reporting unit goodwill with the carrying amount of goodwill.

        Currently, we have one reporting unit, one operating segment and one reportable segment. At December 31, 2013 and 2012, all of the goodwill was attributed to our reporting unit. We tested our goodwill for impairment using a market based approach and no impairment was identified as the fair value of our reporting unit was substantially in excess of its carrying amount. To date, we have not recorded any goodwill impairment charges.

        We generate revenue from several sources including: (i) platform service arrangements with wholesale customers that provide software licensing, network access, and professional services fees, (ii) wholesale customers that are telecom operators under long-term contracts for access to our DAS at our managed and operated locations, (iii) retail customers under subscription plans for month-to-month network access that automatically renew, and retail single-use access from sales of hourly, daily or other single-use access plans, and (iv) display advertisements and sponsorships on our walled garden sign-in pages. Software licensed by our wholesale platform services customers can only be used during the term of the service arrangements and has no utility to them upon termination of the service arrangement.

        We recognize revenue when an arrangement exists, services have been rendered, fees are fixed or determinable, no significant obligations remain related to the earned fees and collection of the related receivable is reasonably assured.

        Services provided to wholesale partners under platform service arrangements generally contain several elements including: (i) a term license to use our software to access our Wi-Fi network, (ii) access fees for network usage, and (iii) professional services for software integration and customization and to maintain the Wi-Fi service. The term license, monthly minimum network access fees and professional services are billed on a monthly basis based upon predetermined fixed rates. Once the term license for integration and customization are delivered, the fees from the arrangement are recognized ratably over the remaining term of the platform service arrangement. The initial term of platform service license agreements is generally between one to five years and the agreements generally contain renewal clauses. Revenue for network access fees in excess of the monthly minimum amounts is recognized when earned. All elements within existing platform service arrangements are generally delivered and earned concurrently throughout the term of the respective service arrangement.

        Revenue generated from access to our DAS networks consists of build-out fees and recurring access fees under certain long-term contracts with telecom operators. Build-out fees paid upfront are generally deferred and recognized ratably over the term of the estimated customer relationship period, once the build-out is complete. Minimum monthly access fees for usage of the DAS networks are non-cancellable and generally escalate on an annual basis. These minimum monthly access fees are recognized ratably over the term of the telecom operator agreement. The initial term of our contracts with telecom operators and wholesale partners generally range from three to fifteen years and the agreements generally contain renewal clauses. Revenue from network access fees in excess of the monthly minimums is recognized when earned.

        In instances where the minimum monthly network access fees escalate over the term of the wholesale service arrangement, an unbilled receivable is recognized when performance is within our control and when we have reasonable assurance that the unbilled receivable balance will be collected.

        We adopted the provisions of Accounting Standards Update ("ASU") 2009-13, Revenue Recognition (Topic 605)—Multiple-Deliverable Revenue Arrangements ("ASU 2009-13"), on a prospective basis on January 1, 2011. For multiple-deliverable arrangements entered into prior to January 1, 2011 that are accounted for under ASC 605-25, Revenue Recognition—Multiple-Deliverable Revenue Arrangements, we defer recognition of revenue for the full arrangement and recognize all revenue ratably over the wholesale service period for platform service arrangements and the term of the estimated customer relationship period for DAS arrangements, as we do not have evidence of fair value for the undelivered elements in the arrangement. For multiple-deliverable arrangements entered into or materially modified after January 1, 2011 that are accounted for under ASC 605-25, we evaluate whether or not separate units of accounting exist and then allocate the arrangement consideration to all units of accounting based on the relative selling price method using estimated selling prices if vendor specific objective evidence and third party evidence is not available. We recognize the revenue associated with the separate units of accounting upon completion of such services or ratably over the wholesale service period for platform service arrangements and the term of the estimated customer relationship period for DAS arrangements.

        Subscription fees from retail customers are paid monthly in advance and revenue is deferred for the portions of monthly recurring subscription fees collected in advance. We do not have a stated or published refund policy for our Wi-Fi service, although our customer service representatives will provide a refund on a case-by-case basis. These amounts are not significant and are recorded as contra-revenue in the period the refunds are made. Subscription fee revenue is recognized ratably over the subscription period. Revenue generated from retail single-use access is recognized when earned.

        Advertising revenue is generated from advertisements on our managed and operated or partner networks. In determining whether an arrangement exists, we ensure that a binding arrangement is in place, such as a standard insertion order or a fully executed customer-specific agreement. Obligations pursuant to our advertising revenue arrangements typically include a minimum number of units or the satisfaction of certain performance criteria. Advertising and other revenue is recognized when the services are performed.

Network access

• Network access

        Network access costs consist primarily of revenue share payments to venue owners where our managed and operated hotspots are located, usage-based fees to our roaming network partners for access to their networks, depreciation of equipment related to network build-out projects in our managed and operated locations, and bandwidth and other Internet connectivity expenses in our managed and operated locations.

Advertising, marketing and promotion costs

• Advertising, marketing and promotion costs

        Advertising production costs are expensed the first time the advertisement is run. No advertising production costs were capitalized for the years ended December 31, 2013, 2012 and 2011. All other costs of advertising, marketing and promotion are expensed as incurred. Advertising expenses charged to operations totaled $2,302, $2,374 and $1,393 for the years ended December 31, 2013, 2012 and 2011, respectively.

Stock-based compensation

• Stock-based compensation

        Our stock-based compensation consists of stock options and restricted stock units ("RSU") granted to employees and non-employees.

        We recognize stock-based compensation expense in accordance with guidance provided by FASB ASC 718, Compensation—Stock Compensation ("ASC 718"). We measure employee stock-based compensation cost at grant date, based on the estimated fair value of the award and recognize the cost on a straight-line basis, net of estimated forfeitures, over the employee requisite service period. We estimate the fair value of stock options using a Black-Scholes option pricing model. The model requires input of assumptions regarding expected term, expected volatility, dividend yield, and a risk-free interest rate. The weighted average assumptions that were used to calculate the grant date fair value of our employee stock option grants for the following periods are as follows:

	December 31,
	2013			2012			2011
Expected term (years)		6.25			5.9			6.4
Expected volatility		49.31	%		48.9	%		49.8	%
Risk-free interest rate		1.34	%		0.9	%		2.4	%
Dividend yield		0	%		0	%		0	%

        The expected term of employee stock options represents the weighted-average period that the stock options are expected to remain outstanding. In estimating the expected term for options granted to employees, we applied the simplified method from the Security Exchange Commission ("SEC") Staff Accounting Bulletin ("SAB") Topic 14, Share-Based Payment ("SAB Topic 14"), where options are granted at-the-money. Where options were not granted at-the-money, the expected term of employee stock options represents the weighted-average period that the stock options are expected to remain outstanding and is calculated based upon actual historical exercise and post-vesting cancellations, adjusted for expected future exercise behavior.

        We determine the fair value of common stock underlying the stock option awards by reference to third party sales of our common stock. Prior to our IPO, the fair value of common stock underlying the stock option awards was determined with the assistance of a third-party valuation specialist.

        We determined the expected volatility assumption using the frequency of daily historical prices of comparable public companies' common stock for a period equal to the expected term of the options in accordance with guidance in ASC 718 and SAB Topic 14. We will continue to monitor peer companies and other relevant factors, including our volatility after there is enough history, used to measure expected volatility for future stock option grants.

        The risk-free interest rate assumption is based upon observed interest rates on the United States government securities appropriate for the expected term of our employee stock options.

        The dividend yield assumption is based on our history and expectation of dividend payouts for which no cash dividends have been declared or paid on our common stock, and for which none are anticipated in the foreseeable future.

        As stock-based compensation expense recognized in our accompanying consolidated statements of operations is based on awards ultimately expected to vest, the amount has been reduced for estimated forfeitures. ASC 718 requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Forfeitures were estimated based on our historical experience and future expectations.

        Compensation expense for non-employee stock-based awards is recognized in accordance with ASC 718 and FASB ASC 505, Equity. Stock option awards issued to non-employees are accounted for at fair value using the Black-Scholes option pricing model. Management believes that the fair value of the stock options is more reliably measured than the fair value of the services received. We record compensation expense based on the then-current fair value of the stock options at each financial reporting date. Compensation recorded during the service period is adjusted in subsequent periods for changes in the stock options' fair value until the earlier of the date at which the non-employee's performance is complete or a performance commitment is reached, which is generally when the stock award vests. There was $30, $372 and $515 of stock-based compensation expense recognized for non-employee stock-based awards for the years ended December 31, 2013, 2012 and 2011, respectively.

Income taxes

• Income taxes

        We account for income taxes in accordance with FASB ASC 740, Accounting for Income Taxes ("ASC 740"), which requires the recognition of deferred tax assets and liabilities for the future consequences of events that have been recognized in our accompanying consolidated financial statements or tax returns. The measurement of the deferred items is based on enacted tax laws. In the event the future consequences of differences between financial reporting bases and the tax bases of our assets and liabilities result in a deferred tax asset, ASC 740 requires an evaluation of the probability of being able to realize the future benefits indicated by such asset. A valuation allowance related to a deferred tax asset is recorded when it is more likely than not that some portion or the entire deferred tax asset will not be realized. As part of the process of preparing our accompanying consolidated financial statements, we are required to estimate our income taxes in each of the jurisdictions in which we operate. We also assess temporary differences resulting from differing treatment of items, such as deferred revenue, for tax and accounting differences. We record a valuation allowance to reduce the deferred tax assets to the amount of future tax benefit that is more likely than not to be realized.

        ASC 740 prescribes a recognition threshold and measurement methodology to recognize and measure an income tax position taken, or expected to be taken, in a tax return. The evaluation of a tax position is based on a two-step approach. The first step requires an entity to evaluate whether the tax position would "more likely than not" be sustained upon examination by the appropriate taxing authority. The second step requires the tax position be measured at the largest amount of tax benefit that is greater than 50% likely of being realized upon ultimate settlement. In addition, previously recognized benefits from tax positions that no longer meet the new criteria would no longer be recognized. Changes in recognition or measurement are reflected in the period in which the change occurs.

Non-controlling interests

• Non-controlling interests

        Non-controlling interests are comprised of minority holdings in Concourse Communications Detroit, LLC ("CCG Detroit"), Chicago Concourse Development Group, LLC ("CCDG") and Boingo Holding Participacoes Ltda ("BHPL").

        Under the terms of the limited liability company ("LLC") agreement for CCG Detroit ("Detroit Operating Agreement") profits and losses are allocated to the controlling and non-controlling owners based on specified terms in the Detroit Operating Agreement which reflect the relative risk and reward of each owner. The profit and loss allocation in the Detroit Operating Agreement specifies that the non-controlling owners' allocated profits are limited to the fixed distribution amounts and losses are limited to the non-controlling owners capital account balance with losses in excess of their capital account being fully allocated to the controlling common unit holder. There is no specified term in the Detroit Operating Agreement, but the term of the annual fixed distribution obligation to the non-controlling owner is the same as the term of the venue agreement between CCG Detroit and Detroit Metropolitan Wayne County Airport—which has a seven year initial term with options to extend for an additional four years. We allocate profits and losses in CCG Detroit based on the attribution in the Detroit Operating Agreement. CCG Detroit has generated losses which reduced the non-controlling owners capital account to zero in 2009 resulting in an allocation to the controlling interest holder all operating losses and deficits created by the annual fixed distributions to the non-controlling interest holder. The fixed distributions were terminated during September 2013 concurrent with the termination of CCG Detroit's agreement with Detroit Metropolitan Wayne County Airport. For the years ended December 31, 2013, 2012 and 2011, we made distributions of $48, $121 and $85, respectively, to non-controlling interest holders of CCG Detroit.

        Under the terms of the LLC agreement for CCDG, we are required to distribute annually to the CCDG non-controlling interest holders 30% of allocated net profits less capital expenditures of the preceding year. For the years ended December 31, 2013, 2012 and 2011, we made distributions of $560, $557 and $462, respectively, to non-controlling interest holders of CCDG.

        BHPL was formed at the end of 2012. Under the terms of the LLC agreement for BHPL, we attributed profits and losses to the non-controlling interest in BHPL in proportion to their holdings. For the year ended December 31, 2013, we made no distributions to the non-controlling interest holder of BHPL.

Convertible preferred stock

• Convertible preferred stock

        The convertible preferred stock contained puttable redemption features and deemed liquidation preferences upon a change-in-control, which were considered outside of the control the Company. Accretion of related issuance costs and dividends were recorded as a charge against retained earnings, or in the absence of retained earnings by charges against additional paid-in capital until fully depleted, then against the accumulated deficit. We accrete issuance costs and dividends to the earliest redemption date. For the year ended December 31, 2011, we accreted our convertible preferred stock through to their conversion date into common stock on May 3, 2011 in connection with our IPO. At December 31, 2013 and 2012, we had no preferred stock issued or outstanding.

Warrants exercisable into convertible preferred stock

• Warrants exercisable into convertible preferred stock

        We account for preferred stock warrants as liabilities when the underlying preferred stock contains either puttable or mandatorily redeemable features. We issued warrants which were exercisable into the Series B convertible preferred stock in connection with capital lease arrangements. We determined that the preferred stock warrants contained puttable features as a result of the redemption provisions and deemed liquidation preferences upon a change-in-control. Accordingly, the warrants were recorded as a non-current liability and were carried at their fair value at date of issuance with decreases or increases in fair value at each reporting date recorded as other income or expense through to the final measurement date upon the exercise of the warrants. The warrants were exercisable either through cash payment of the exercise price or through net-share settlement at the option of the holder. Our preferred stock warrants outstanding of 25,196 were exercised and converted under the net-share settlement provisions into 20,172 shares of our common stock on May 3, 2011, in connection with our IPO.

Net (loss) income per share attributable to common stockholders

• Net (loss) income per share attributable to common stockholders

        Basic net (loss) income per share attributable to common stockholders is calculated by dividing (loss) income attributable to common stockholders by the weighted average number of shares of common stock outstanding during the period. Diluted net income per share attributable to common stockholders adjusts the basic weighted average number of shares of common stock outstanding for the potential dilution that could occur if stock options, RSUs, common stock warrants, preferred stock warrants and the convertible preferred stock were exercised or converted into common stock. Our convertible preferred stockholders were entitled to receive dividends and were not contractually obligated to share in our net income with common stockholders. The common stockholders are not entitled to receive any dividends.

Segment and geographic information

• Segment and geographic information

        We operate as one reportable segment; a service provider of mobile Internet solutions across our managed and operated network and aggregated network for mobile devices such as laptops, smartphones, tablet computers and other wireless-enabled consumer devices. This single segment is consistent with the internal organization structure and the manner in which operations are reviewed and managed by our Chief Executive Officer, the chief operating decision maker.

        Revenue is predominantly generated and all significant long-lived tangible assets are held in the United States of America. We do not disclose sales by geographic area because to do so would be impracticable. The following is a summary of our revenue by primary revenue source:

	Year Ended December 31,

        Certain 2012 and 2011 amounts have been reclassified to conform to the current year presentation.

Recent accounting pronouncements

• Recent accounting pronouncements

        In July 2013, the FASB issued ASU 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists ("ASU 2013-11"). This ASU requires the netting of unrecognized tax benefits (UTBs) against a deferred tax asset for a loss or other carryforward that would apply in the settlement of the uncertain tax positions. The UTBs will be netted against all available same-jurisdiction loss or other tax carryforwards that would be utilized, rather than only against carryforwards that are created by the UTBs. ASU 2013-11 will require prospective application with optional retrospective application, and will be effective for reporting periods beginning after December 15, 2013. Early adoption is permitted. We have effectively adopted the provisions of this requirement as of the date of issuance of ASU 2013-11 as we have historically presented our UTBs as a reduction of our deferred tax assets for a loss or other carryforward rather than as a liability when the uncertain tax position would reduce the loss or other carryforward under the tax law.

        In February 2013, the FASB issued ASU 2013-02, Comprehensive Income—Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income ("ASU 2013-02"). This ASU requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income ("AOCI") by component. In addition, an entity is required to present, either on the face of the statement where net income (loss) is presented or in the notes, significant amounts reclassified out of AOCI by the respective line items of net income (loss) but only if the amount reclassified is required under GAAP to be reclassified to net income (loss) in its entirety in the same reporting period. For other amounts that are not required under GAAP to be reclassified in their entirety to net income (loss), an entity is required to cross-reference to other disclosures required under GAAP that provide additional detail about those amounts. ASU 2013-02 was effective prospectively for reporting periods beginning after December 15, 2012. We adopted this standard effective January 1, 2013. The adoption of this standard did not have any impact on our consolidated financial statements.

3. Acquisitions

• Electronic Media Systems, Inc. and Advanced Wireless Group, LLC

        On October 31, 2013, we acquired all outstanding stock of Electronic Media Systems, Inc. and all membership interests in its subsidiary, Advanced Wireless Group, LLC, not otherwise owned by Electronic Media Systems, Inc. such that we are now the beneficial owner of all membership interests of Advanced Wireless, Group, LLC (collectively, "AWG"). AWG operates public Wi-Fi in seventeen U.S. airports including Los Angeles International, Charlotte/Douglas International, Miami International, Minneapolis-St. Paul International, Detroit Metropolitan Airport, and Boston's Logan International. We have included the operating results of AWG in our consolidated financial statements since the date of acquisition.

        The acquisition has been accounted for under the acquisition method of accounting in accordance with FASB ASC 805, Business Combinations. As such, the assets acquired and liabilities assumed are recorded at their acquisition-date fair values. The total purchase price was $17,380, which includes cash paid at closing, holdback consideration to be paid and the fair value of additional contingent consideration that would be due and payable upon the successful extension of a specified airport Wi-Fi contract. The total purchase price includes estimated net equity adjustments that may be subject to additional adjustments.

        The fair value of the contingent consideration is based on Level 3 inputs. Further changes in the fair value of the contingent consideration will be recorded through operating (loss) income. We allocated the excess of the purchase price over the fair value of assets acquired and liabilities assumed to goodwill, which is primarily not deductible for tax purposes. The goodwill arising from the AWG acquisition is attributable primarily to expected synergies and other benefits, including the acquired workforce, from combining AWG with us.

        The deferred tax liabilities are provisional pending the filing of AWG's final short period 2013 tax returns. The contingent consideration was valued at the date of acquisition using a discount rate of 3.1% and is expected to be paid in 2014. The identifiable intangible assets were primarily valued using the excess earnings, relief from royalty, with-and-without and replacement cost methods using discount rates ranging from 12.0% to 14.0% and royalty rates of 0.5%.

        The amortizable intangible assets are being amortized straight-line over their estimated useful lives. The following summarizes the preliminary purchase price allocation:

	Estimated Fair Value			Weighted Average Estimated Useful Life (years)
Consideration:
Cash paid	$	14,800
Holdback consideration		1,600
Contingent consideration		980
Total consideration	$	17,380
Recognized amounts of identifiable assets acquired and liabilities assumed:
Cash	$	215
Restricted cash		515
Accounts receivable		988
Other current assets		609

• Endeka Group, Inc.

        On February 22, 2013, we acquired all outstanding stock of Endeka Group, Inc. ("Endeka"). Endeka is a provider of commercial wireless broadband and IPTV services at certain military bases, as well as Wi-Fi services to certain federal law enforcement training facilities. We acquired Endeka because Endeka's portfolio of venues and management team are natural additions to our managed network business. We have included the operating results of Endeka in our consolidated financial statements since the date of acquisition.

        The acquisition has been accounted for under the acquisition method of accounting in accordance with FASB ASC 805. As such, the assets acquired and liabilities assumed are recorded at their acquisition-date fair values. The total purchase price was $6,498, which includes cash paid at closing, holdback consideration to be paid and the fair value of additional contingent consideration comprised of two components: (i) a payment ("Build Payment") if the amount of the capital expenditures incurred for the substantial completion of a specified build project is less than a target; and (ii) a payment ("Milestone Payment") based on revenue generated by certain contracts in fiscal year 2014. There is no maximum to the contingent consideration payments for the Milestone Payment. We do not expect to make any payments associated with the Build Payment. The holdback consideration will be paid in 2014 and the Milestone Payment will be paid on February 28, 2015.

        The fair value of the contingent consideration is based on Level 3 inputs. Further changes in the fair value of the contingent consideration will be recorded through operating (loss) income. We allocated the excess of the purchase price over the fair value of assets acquired and liabilities assumed to goodwill, which is not deductible for tax purposes. The goodwill arising from the Endeka acquisition is attributable primarily to expected synergies and other benefits, including the acquired workforce, from combining Endeka with us.

        The contingent consideration was valued at the date of acquisition using a discounted cash flow method with probability weighted cash flows and a discount rate of 50.5%. The identifiable intangible assets were primarily valued using the excess earnings, relief from royalty, and replacement cost methods using discount rates ranging from 40.0% to 50.0% and royalty rates ranging from 0.5% to 1.5%, where applicable.

        The amortizable intangible assets are being amortized straight-line over their estimated useful lives. The following summarizes the final purchase price allocation:

	Estimated Fair Value			Estimated Useful Life (years)
Consideration:
Cash paid	$	4,894
Holdback consideration		275

• Pro forma results (Unaudited)

        The following table presents the unaudited pro forma results of the Company for the years ended December 31, 2013 and 2012 as if the acquisitions of Endeka and AWG had occurred on January 1, 2012. These results are not intended to reflect the actual operations of the Company had the acquisition occurred on January 1, 2012. Acquisition transaction costs have been excluded from the pro forma net (loss) income. We did not record any incremental income taxes for pro forma net (loss) income because we established a valuation allowance in 2013. Income taxes for purposes of the 2012 pro forma net (loss) income were computed based on the statutory tax rates.

• Cloud 9 Wireless, Inc.

        On August 6, 2012, we acquired the assets of Cloud 9 Wireless, Inc. ("Cloud 9") for $3,500 plus the assumption of certain liabilities. Cloud 9 provides Wi-Fi sponsorship and location-based advertising at airports, hotels, bars and restaurants, and recreational areas in the U.S. and Canada. The acquisition has been accounted for under the acquisition method of accounting in accordance with the FASB ASC 805. The excess of the acquisition consideration over the fair value of assets acquired and liabilities assumed is allocated to goodwill, which is deductible for tax purposes. Goodwill is attributable primarily to expected synergies and other benefits, including the acquired workforce, from combining Cloud 9 with us. Cloud 9 was consolidated into our results of operations starting August 6, 2012, the acquisition date. Cloud 9 has been integrated into the Company's product offering; therefore, it is not practical to disclose actual and pro forma financial results for Cloud 9 since the acquisition.

        The following table summarizes the allocation of the total purchase price as of August 6, 2012:

Current assets	$	899
Property, plant and equipment		65
Intangible and other assets		1,758
Goodwill		1,232
Current liabilities		(454	)
Net assets acquired	$	3,500

        The intangible assets are all definite-lived intangibles and are recognized on a straight-line basis over their weighted average lives of approximately 5 years.

Summary of significant accounting policies

Summary of significant accounting policies

2. Summary of significant accounting policies

• Basis of presentation and consolidation

        Our consolidated financial statements for the years ended December 31, 2013, 2012 and 2011 have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP").

        The accompanying consolidated financial statements include our accounts and our majority owned subsidiaries. We consolidate our 70% ownership of Concourse Communications Detroit, LLC, our 70% ownership of Chicago Concourse Development Group, LLC and our 75% ownership of Boingo Holding Participacoes Ltda. in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 810, Consolidation. Other parties' interests in consolidated entities are reported as non-controlling interests. All intercompany balances and transactions have been eliminated in consolidation.

        During the year ended December 31, 2013, the Company recorded certain out-of-period adjustments that decreased net loss attributable to common stockholders by $217. The impact of these out-of-period adjustments is not considered material, individually and in the aggregate, to any of the current or prior annual periods.

        The consolidated balance sheet as of December 31, 2012 has been revised to properly classify $2,066 of unbilled receivables from other non-current assets to accounts receivable, net. The revision has also been reflected in Note 5 to the consolidated financial statements. The impact of this revision is not material to the prior year consolidated balance sheet.

• Use of estimates

        The preparation of accompanying consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the dates of the accompanying consolidated financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Assets and liabilities which are subject to significant judgment and the use of estimates include the allowance for doubtful accounts, recoverability of goodwill and long-lived assets, valuation allowances with respect to deferred tax assets, uncertain tax positions, useful lives associated with property and equipment, valuation and useful lives of intangible assets, valuation of contingent consideration, and the valuation and assumptions underlying stock-based compensation and other equity instruments. On an ongoing basis, we evaluate our estimates compared to historical experience and trends, which form the basis for making judgments about the carrying value of assets and liabilities. In addition, prior to our IPO, we regularly engaged the assistance of valuation specialists in determining fair value measurements in connection with stock-based compensation and other equity instruments.

• Concentrations of credit risk

        Financial instruments that potentially subject us to significant concentrations of credit risk consist primarily of cash and cash equivalents, restricted cash, marketable securities and accounts receivable. We maintain our cash and cash equivalents, restricted cash and marketable securities with institutions with high credit ratings. We extend credit based upon the evaluation of the customer's financial condition and generally collateral is not required. We maintain an allowance for doubtful accounts based upon expected collectability of accounts receivable. We primarily estimate our allowance for doubtful accounts based on a specific review of significant outstanding accounts receivable. For the year ended December 31, 2013 two groups of affiliated entities each accounted for 14% of total revenue. For the year ended December 31, 2012, those same two groups of affiliated entities accounted for 17% and 15% of total revenue, respectively. For the year ended December 31, 2011, one group of affiliated entities accounted for 18% of total revenue. At December 31, 2013, one group of affiliated entities accounted for 12% of the total accounts receivable. At December 31, 2012, three groups of affiliated entities accounted for 26%, 16% and 10% of the total accounts receivable, respectively.

• Cash and cash equivalents

        Cash and cash equivalents include highly liquid investments that are readily convertible into known amounts of cash with original maturities of three months or less when acquired. At December 31, 2013, cash equivalents consisted of money market funds. At December 31, 2012, cash equivalents consisted of money market funds and marketable securities with original maturities of three months or less.

• Marketable securities

        Our marketable securities consist of available-for-sale securities with original maturities exceeding three months. In accordance with FASB ASC 320, Investments—Debt and Equity Securities, we have classified securities, which have readily determinable fair values and are highly liquid, as short-term because such securities are expected to be realized within a one- year period. At December 31, 2013 and 2012, we had $32,962 and $41,558, respectively, in short-term marketable securities and no long-term marketable securities.

        Marketable securities are reported at fair value with the related unrealized gains and losses reported as other comprehensive income (loss) until realized or until a determination is made that an other-than-temporary decline in market value has occurred. No significant unrealized gains and losses have been reported during the years presented. Factors considered by us in assessing whether an other-than-temporary impairment has occurred include the nature of the investment, whether the decline in fair value is attributable to specific adverse conditions affecting the investment, the financial condition of the investee, the severity and the duration of the impairment and whether we have the ability to hold the investment to maturity. When it is determined that an other-than-temporary impairment has occurred, the investment is written down to its market value at the end of the period in which it is determined that an other-than-temporary decline has occurred. The cost of marketable securities sold is based upon the specific identification method. Any realized gains or losses on the sale of investments are reflected as a component of interest and other income (expense), net.

        For the years ended December 31, 2013, 2012 and 2011, we had no significant realized or unrealized gains or losses from investments in marketable securities classified as available-for-sale.

• Restricted cash

        Restricted cash consists of letters of credit with our landlords, municipalities or venues for which we have operating agreements. Letters of credit are supported by cash deposits made by us and invested into bank certificates of deposit. At December 31, 2013 and 2012, we had $545 and $30 classified as short-term restricted cash, respectively. At December 31, 2013 and 2012, we had no restricted cash classified as long-term.

• Fair value of financial instruments

        Fair value is defined as the price that would be received from selling an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, we consider the principal or most advantageous market in which it would transact, and we consider assumptions that market participants would use when pricing the asset or liability.

        The accounting guidance for fair value measurement also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard establishes a fair value hierarchy based on the level of independent, objective evidence surrounding the inputs used to measure fair value. A financial instrument's categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The fair value hierarchy is as follows:

• •

  Level 1—Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.

  •

  Level 2—Quoted prices for identical assets and liabilities in markets that are not active, quoted prices for similar assets and liabilities in active markets or financial instruments for which significant inputs are observable, either directly or indirectly.

  •

  Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

        The carrying amount reflected in the accompanying consolidated balance sheets for cash and cash equivalents, restricted cash, marketable securities, accounts receivable, prepaid expenses and other current assets, accounts payable, accrued expenses and other liabilities approximates fair value due to the short-term nature of these financial instruments.

• Business combinations

        The results of businesses acquired in a business combination are included in the Company's consolidated financial statements from the date of the acquisition. Purchase accounting results in assets and liabilities of an acquired business being recorded at their estimated fair values on the acquisition date. Any excess consideration over the fair value of assets acquired and liabilities assumed is recognized as goodwill.

        The Company performs valuations of assets acquired and liabilities assumed from a business acquisition and will allocate the purchase price to its respective net tangible and intangible assets. Determining the fair value of assets acquired and liabilities assumed requires management to use significant judgment and estimates including the selection of valuation methodologies, estimates of future revenues and cash flows, discount rates, royalty rates and selection of comparable companies. The Company engages the assistance of valuation specialists in concluding on fair value measurements in connection with fair values of assets and liabilities assumed in a business combination.

        Transaction costs associated with business combinations are expensed as incurred, and are included in general and administrative expenses in the consolidated statements of operations. Transaction costs were $354 and $50 for the years ended December 31, 2013 and 2012, respectively. There were no transaction costs for the year ended December 31, 2011.

• Property and equipment

        Property and equipment are generally stated at historical cost, less accumulated depreciation and amortization. The Company's cost basis includes property and equipment acquired in business combinations that were initially recorded at fair value as of the date of acquisition. Maintenance and repairs are charged to expense as incurred and the cost of additions and betterments that increase the useful lives of the assets are capitalized. Depreciation and amortization is computed over the estimated useful lives of the related asset type using the straight-line method.

        The estimated useful lives for property and equipment are as follows:

Computer equipment	2 to 5 years
Software	2 to 5 years
Office equipment	3 to 5 years
Leasehold improvements	The shorter of the estimated useful life or the remaining term of the agreements, generally ranging from 2 to 15 years

        Leasehold improvements are principally comprised of network equipment located at various managed and operated locations, primarily airports, under exclusive, long-term, non-cancelable contracts to provide wireless communication network access.

• Equipment and software under capital lease

        We lease certain data communications equipment, other equipment and software under capital lease agreements. The assets and liabilities under capital lease are recorded at the lesser of the present value of aggregate future minimum lease payments, including estimated bargain purchase options, or the fair value of the asset under lease. Assets under capital lease are depreciated using the straight-line method over the shorter of the estimated useful lives of the assets or the term of the lease agreements.

• Software development costs

        We capitalize costs associated with software developed or obtained for internal use when the preliminary project stage is completed and it is determined that the software will provide significantly enhanced capabilities and modifications. These capitalized costs are included in property and equipment and include external direct cost of services procured in developing or obtaining internal-use software and personnel and related expenses for employees who are directly associated with, and who devote time to internal-use software projects. Capitalization of these costs ceases once the project is substantially complete and the software is ready for its intended use. Once the software is ready for its intended use, the costs are amortized over the useful life of the software. Post-configuration training and maintenance costs are expensed as incurred.

• Long-lived assets

        Intangible assets consist of acquired venue contracts, technology, advertiser relationships, non-compete agreements and patents and trademarks. We record intangible assets at fair value as of the date of acquisition and amortize these finite-lived assets over the shorter of the contractual life or the estimated useful life on a straight-line basis. We estimate the useful lives of acquired intangible assets based on factors that include the planned use of each acquired intangible asset, the expected pattern of future cash flows to be derived from each acquired intangible asset and contractual periods specified in the related agreements. As such, we account for each of the venue contracts individually. We include amortization of acquired intangibles in amortization of intangible assets in the accompanying consolidated statements of operations.

        We perform an impairment review of long-lived assets held and used whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Factors we consider important that could trigger an impairment review include, but are not limited to: significant under-performance relative to projected future operating results, significant changes in the manner of our use of the acquired assets or our overall business and product strategies and significant industry or economic trends. When we determine that the carrying value of a long-lived asset may not be recoverable based upon the existence of one or more of these indicators, we determine the recoverability by comparing the carrying amount of the asset to net future undiscounted cash flows that the asset is expected to generate or other indices of fair value. We would then recognize an impairment charge equal to the amount by which the carrying amount exceeds the fair market value of the asset.

• Goodwill

        Goodwill represents the excess of the purchase price over the fair value of net assets acquired in connection with the acquisition of Concourse Communication Group, LLC in June 2006, Cloud 9 Wireless, Inc. in August 2012, Endeka Group, Inc. in February 2013, and Electronic Media Systems, Inc. and Advanced Wireless Group, LLC in October 2013.

        We test goodwill for impairment in accordance with guidance provided by FASB ASC 350, Intangibles—Goodwill and Other ("ASC 350"). Goodwill is tested for impairment at least annually at the reporting unit level or whenever events or changes in circumstances indicate that goodwill might be impaired. Events or changes in circumstances which could trigger an impairment review include a significant adverse change in legal factors or in the business climate, an adverse action or assessment by a regulator, unanticipated competition, a loss of key personnel, significant changes in the manner of our use of the acquired assets or the strategy for our overall business, significant negative industry or economic trends, or significant underperformance relative to expected historical or projected future results of operations. We perform our impairment test annually as of December 31^st.

        Entities have the option to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test described in FASB ASC 350. If, after assessing qualitative factors, an entity determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then performing the two-step impairment test is unnecessary. If deemed necessary, a two-step test is used to identify the potential impairment and to measure the amount of goodwill impairment, if any. The first step is to compare the fair value of the reporting unit with its carrying amount, including goodwill. If the fair value of the reporting unit exceeds its carrying amount, goodwill is considered not impaired; otherwise, there is an indication that goodwill may be impaired and the amount of the loss, if any, is measured by performing step two. Under step two, the impairment loss, if any, is measured by comparing the implied fair value of the reporting unit goodwill with the carrying amount of goodwill.

        Currently, we have one reporting unit, one operating segment and one reportable segment. At December 31, 2013 and 2012, all of the goodwill was attributed to our reporting unit. We tested our goodwill for impairment using a market based approach and no impairment was identified as the fair value of our reporting unit was substantially in excess of its carrying amount. To date, we have not recorded any goodwill impairment charges.

• Revenue recognition

        We generate revenue from several sources including: (i) platform service arrangements with wholesale customers that provide software licensing, network access, and professional services fees, (ii) wholesale customers that are telecom operators under long-term contracts for access to our DAS at our managed and operated locations, (iii) retail customers under subscription plans for month-to-month network access that automatically renew, and retail single-use access from sales of hourly, daily or other single-use access plans, and (iv) display advertisements and sponsorships on our walled garden sign-in pages. Software licensed by our wholesale platform services customers can only be used during the term of the service arrangements and has no utility to them upon termination of the service arrangement.

        We recognize revenue when an arrangement exists, services have been rendered, fees are fixed or determinable, no significant obligations remain related to the earned fees and collection of the related receivable is reasonably assured.

        Services provided to wholesale partners under platform service arrangements generally contain several elements including: (i) a term license to use our software to access our Wi-Fi network, (ii) access fees for network usage, and (iii) professional services for software integration and customization and to maintain the Wi-Fi service. The term license, monthly minimum network access fees and professional services are billed on a monthly basis based upon predetermined fixed rates. Once the term license for integration and customization are delivered, the fees from the arrangement are recognized ratably over the remaining term of the platform service arrangement. The initial term of platform service license agreements is generally between one to five years and the agreements generally contain renewal clauses. Revenue for network access fees in excess of the monthly minimum amounts is recognized when earned. All elements within existing platform service arrangements are generally delivered and earned concurrently throughout the term of the respective service arrangement.

        Revenue generated from access to our DAS networks consists of build-out fees and recurring access fees under certain long-term contracts with telecom operators. Build-out fees paid upfront are generally deferred and recognized ratably over the term of the estimated customer relationship period, once the build-out is complete. Minimum monthly access fees for usage of the DAS networks are non-cancellable and generally escalate on an annual basis. These minimum monthly access fees are recognized ratably over the term of the telecom operator agreement. The initial term of our contracts with telecom operators and wholesale partners generally range from three to fifteen years and the agreements generally contain renewal clauses. Revenue from network access fees in excess of the monthly minimums is recognized when earned.

        In instances where the minimum monthly network access fees escalate over the term of the wholesale service arrangement, an unbilled receivable is recognized when performance is within our control and when we have reasonable assurance that the unbilled receivable balance will be collected.

        We adopted the provisions of Accounting Standards Update ("ASU") 2009-13, Revenue Recognition (Topic 605)—Multiple-Deliverable Revenue Arrangements ("ASU 2009-13"), on a prospective basis on January 1, 2011. For multiple-deliverable arrangements entered into prior to January 1, 2011 that are accounted for under ASC 605-25, Revenue Recognition—Multiple-Deliverable Revenue Arrangements, we defer recognition of revenue for the full arrangement and recognize all revenue ratably over the wholesale service period for platform service arrangements and the term of the estimated customer relationship period for DAS arrangements, as we do not have evidence of fair value for the undelivered elements in the arrangement. For multiple-deliverable arrangements entered into or materially modified after January 1, 2011 that are accounted for under ASC 605-25, we evaluate whether or not separate units of accounting exist and then allocate the arrangement consideration to all units of accounting based on the relative selling price method using estimated selling prices if vendor specific objective evidence and third party evidence is not available. We recognize the revenue associated with the separate units of accounting upon completion of such services or ratably over the wholesale service period for platform service arrangements and the term of the estimated customer relationship period for DAS arrangements.

        Subscription fees from retail customers are paid monthly in advance and revenue is deferred for the portions of monthly recurring subscription fees collected in advance. We do not have a stated or published refund policy for our Wi-Fi service, although our customer service representatives will provide a refund on a case-by-case basis. These amounts are not significant and are recorded as contra-revenue in the period the refunds are made. Subscription fee revenue is recognized ratably over the subscription period. Revenue generated from retail single-use access is recognized when earned.

        Advertising revenue is generated from advertisements on our managed and operated or partner networks. In determining whether an arrangement exists, we ensure that a binding arrangement is in place, such as a standard insertion order or a fully executed customer-specific agreement. Obligations pursuant to our advertising revenue arrangements typically include a minimum number of units or the satisfaction of certain performance criteria. Advertising and other revenue is recognized when the services are performed.

• Network access

        Network access costs consist primarily of revenue share payments to venue owners where our managed and operated hotspots are located, usage-based fees to our roaming network partners for access to their networks, depreciation of equipment related to network build-out projects in our managed and operated locations, and bandwidth and other Internet connectivity expenses in our managed and operated locations.

• Advertising, marketing and promotion costs

        Advertising production costs are expensed the first time the advertisement is run. No advertising production costs were capitalized for the years ended December 31, 2013, 2012 and 2011. All other costs of advertising, marketing and promotion are expensed as incurred. Advertising expenses charged to operations totaled $2,302, $2,374 and $1,393 for the years ended December 31, 2013, 2012 and 2011, respectively.

• Stock-based compensation

        Our stock-based compensation consists of stock options and restricted stock units ("RSU") granted to employees and non-employees.

        We recognize stock-based compensation expense in accordance with guidance provided by FASB ASC 718, Compensation—Stock Compensation ("ASC 718"). We measure employee stock-based compensation cost at grant date, based on the estimated fair value of the award and recognize the cost on a straight-line basis, net of estimated forfeitures, over the employee requisite service period. We estimate the fair value of stock options using a Black-Scholes option pricing model. The model requires input of assumptions regarding expected term, expected volatility, dividend yield, and a risk-free interest rate. The weighted average assumptions that were used to calculate the grant date fair value of our employee stock option grants for the following periods are as follows:

	December 31,
	2013			2012			2011
Expected term (years)		6.25			5.9			6.4
Expected volatility		49.31	%		48.9	%		49.8	%
Risk-free interest rate		1.34	%		0.9	%		2.4	%
Dividend yield		0	%		0	%		0	%

        The expected term of employee stock options represents the weighted-average period that the stock options are expected to remain outstanding. In estimating the expected term for options granted to employees, we applied the simplified method from the Security Exchange Commission ("SEC") Staff Accounting Bulletin ("SAB") Topic 14, Share-Based Payment ("SAB Topic 14"), where options are granted at-the-money. Where options were not granted at-the-money, the expected term of employee stock options represents the weighted-average period that the stock options are expected to remain outstanding and is calculated based upon actual historical exercise and post-vesting cancellations, adjusted for expected future exercise behavior.

        We determine the fair value of common stock underlying the stock option awards by reference to third party sales of our common stock. Prior to our IPO, the fair value of common stock underlying the stock option awards was determined with the assistance of a third-party valuation specialist.

        We determined the expected volatility assumption using the frequency of daily historical prices of comparable public companies' common stock for a period equal to the expected term of the options in accordance with guidance in ASC 718 and SAB Topic 14. We will continue to monitor peer companies and other relevant factors, including our volatility after there is enough history, used to measure expected volatility for future stock option grants.

        The risk-free interest rate assumption is based upon observed interest rates on the United States government securities appropriate for the expected term of our employee stock options.

        The dividend yield assumption is based on our history and expectation of dividend payouts for which no cash dividends have been declared or paid on our common stock, and for which none are anticipated in the foreseeable future.

        As stock-based compensation expense recognized in our accompanying consolidated statements of operations is based on awards ultimately expected to vest, the amount has been reduced for estimated forfeitures. ASC 718 requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Forfeitures were estimated based on our historical experience and future expectations.

        Compensation expense for non-employee stock-based awards is recognized in accordance with ASC 718 and FASB ASC 505, Equity. Stock option awards issued to non-employees are accounted for at fair value using the Black-Scholes option pricing model. Management believes that the fair value of the stock options is more reliably measured than the fair value of the services received. We record compensation expense based on the then-current fair value of the stock options at each financial reporting date. Compensation recorded during the service period is adjusted in subsequent periods for changes in the stock options' fair value until the earlier of the date at which the non-employee's performance is complete or a performance commitment is reached, which is generally when the stock award vests. There was $30, $372 and $515 of stock-based compensation expense recognized for non-employee stock-based awards for the years ended December 31, 2013, 2012 and 2011, respectively.

• Income taxes

        We account for income taxes in accordance with FASB ASC 740, Accounting for Income Taxes ("ASC 740"), which requires the recognition of deferred tax assets and liabilities for the future consequences of events that have been recognized in our accompanying consolidated financial statements or tax returns. The measurement of the deferred items is based on enacted tax laws. In the event the future consequences of differences between financial reporting bases and the tax bases of our assets and liabilities result in a deferred tax asset, ASC 740 requires an evaluation of the probability of being able to realize the future benefits indicated by such asset. A valuation allowance related to a deferred tax asset is recorded when it is more likely than not that some portion or the entire deferred tax asset will not be realized. As part of the process of preparing our accompanying consolidated financial statements, we are required to estimate our income taxes in each of the jurisdictions in which we operate. We also assess temporary differences resulting from differing treatment of items, such as deferred revenue, for tax and accounting differences. We record a valuation allowance to reduce the deferred tax assets to the amount of future tax benefit that is more likely than not to be realized.

        ASC 740 prescribes a recognition threshold and measurement methodology to recognize and measure an income tax position taken, or expected to be taken, in a tax return. The evaluation of a tax position is based on a two-step approach. The first step requires an entity to evaluate whether the tax position would "more likely than not" be sustained upon examination by the appropriate taxing authority. The second step requires the tax position be measured at the largest amount of tax benefit that is greater than 50% likely of being realized upon ultimate settlement. In addition, previously recognized benefits from tax positions that no longer meet the new criteria would no longer be recognized. Changes in recognition or measurement are reflected in the period in which the change occurs.

• Non-controlling interests

        Non-controlling interests are comprised of minority holdings in Concourse Communications Detroit, LLC ("CCG Detroit"), Chicago Concourse Development Group, LLC ("CCDG") and Boingo Holding Participacoes Ltda ("BHPL").

        Under the terms of the limited liability company ("LLC") agreement for CCG Detroit ("Detroit Operating Agreement") profits and losses are allocated to the controlling and non-controlling owners based on specified terms in the Detroit Operating Agreement which reflect the relative risk and reward of each owner. The profit and loss allocation in the Detroit Operating Agreement specifies that the non-controlling owners' allocated profits are limited to the fixed distribution amounts and losses are limited to the non-controlling owners capital account balance with losses in excess of their capital account being fully allocated to the controlling common unit holder. There is no specified term in the Detroit Operating Agreement, but the term of the annual fixed distribution obligation to the non-controlling owner is the same as the term of the venue agreement between CCG Detroit and Detroit Metropolitan Wayne County Airport—which has a seven year initial term with options to extend for an additional four years. We allocate profits and losses in CCG Detroit based on the attribution in the Detroit Operating Agreement. CCG Detroit has generated losses which reduced the non-controlling owners capital account to zero in 2009 resulting in an allocation to the controlling interest holder all operating losses and deficits created by the annual fixed distributions to the non-controlling interest holder. The fixed distributions were terminated during September 2013 concurrent with the termination of CCG Detroit's agreement with Detroit Metropolitan Wayne County Airport. For the years ended December 31, 2013, 2012 and 2011, we made distributions of $48, $121 and $85, respectively, to non-controlling interest holders of CCG Detroit.

        Under the terms of the LLC agreement for CCDG, we are required to distribute annually to the CCDG non-controlling interest holders 30% of allocated net profits less capital expenditures of the preceding year. For the years ended December 31, 2013, 2012 and 2011, we made distributions of $560, $557 and $462, respectively, to non-controlling interest holders of CCDG.

        BHPL was formed at the end of 2012. Under the terms of the LLC agreement for BHPL, we attributed profits and losses to the non-controlling interest in BHPL in proportion to their holdings. For the year ended December 31, 2013, we made no distributions to the non-controlling interest holder of BHPL.

• Convertible preferred stock

        The convertible preferred stock contained puttable redemption features and deemed liquidation preferences upon a change-in-control, which were considered outside of the control the Company. Accretion of related issuance costs and dividends were recorded as a charge against retained earnings, or in the absence of retained earnings by charges against additional paid-in capital until fully depleted, then against the accumulated deficit. We accrete issuance costs and dividends to the earliest redemption date. For the year ended December 31, 2011, we accreted our convertible preferred stock through to their conversion date into common stock on May 3, 2011 in connection with our IPO. At December 31, 2013 and 2012, we had no preferred stock issued or outstanding.

• Warrants exercisable into convertible preferred stock

        We account for preferred stock warrants as liabilities when the underlying preferred stock contains either puttable or mandatorily redeemable features. We issued warrants which were exercisable into the Series B convertible preferred stock in connection with capital lease arrangements. We determined that the preferred stock warrants contained puttable features as a result of the redemption provisions and deemed liquidation preferences upon a change-in-control. Accordingly, the warrants were recorded as a non-current liability and were carried at their fair value at date of issuance with decreases or increases in fair value at each reporting date recorded as other income or expense through to the final measurement date upon the exercise of the warrants. The warrants were exercisable either through cash payment of the exercise price or through net-share settlement at the option of the holder. Our preferred stock warrants outstanding of 25,196 were exercised and converted under the net-share settlement provisions into 20,172 shares of our common stock on May 3, 2011, in connection with our IPO.

• Net (loss) income per share attributable to common stockholders

        Basic net (loss) income per share attributable to common stockholders is calculated by dividing (loss) income attributable to common stockholders by the weighted average number of shares of common stock outstanding during the period. Diluted net income per share attributable to common stockholders adjusts the basic weighted average number of shares of common stock outstanding for the potential dilution that could occur if stock options, RSUs, common stock warrants, preferred stock warrants and the convertible preferred stock were exercised or converted into common stock. Our convertible preferred stockholders were entitled to receive dividends and were not contractually obligated to share in our net income with common stockholders. The common stockholders are not entitled to receive any dividends.

• Segment and geographic information

        We operate as one reportable segment; a service provider of mobile Internet solutions across our managed and operated network and aggregated network for mobile devices such as laptops, smartphones, tablet computers and other wireless-enabled consumer devices. This single segment is consistent with the internal organization structure and the manner in which operations are reviewed and managed by our Chief Executive Officer, the chief operating decision maker.

        Revenue is predominantly generated and all significant long-lived tangible assets are held in the United States of America. We do not disclose sales by geographic area because to do so would be impracticable. The following is a summary of our revenue by primary revenue source:

	Year Ended December 31,
	2013		2012		2011
Revenue:
Wholesale	$	49,942	$	49,495	$	43,707

• Reclassifications

        Certain 2012 and 2011 amounts have been reclassified to conform to the current year presentation.

• Recent accounting pronouncements

        In July 2013, the FASB issued ASU 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists ("ASU 2013-11"). This ASU requires the netting of unrecognized tax benefits (UTBs) against a deferred tax asset for a loss or other carryforward that would apply in the settlement of the uncertain tax positions. The UTBs will be netted against all available same-jurisdiction loss or other tax carryforwards that would be utilized, rather than only against carryforwards that are created by the UTBs. ASU 2013-11 will require prospective application with optional retrospective application, and will be effective for reporting periods beginning after December 15, 2013. Early adoption is permitted. We have effectively adopted the provisions of this requirement as of the date of issuance of ASU 2013-11 as we have historically presented our UTBs as a reduction of our deferred tax assets for a loss or other carryforward rather than as a liability when the uncertain tax position would reduce the loss or other carryforward under the tax law.

        In February 2013, the FASB issued ASU 2013-02, Comprehensive Income—Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income ("ASU 2013-02"). This ASU requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income ("AOCI") by component. In addition, an entity is required to present, either on the face of the statement where net income (loss) is presented or in the notes, significant amounts reclassified out of AOCI by the respective line items of net income (loss) but only if the amount reclassified is required under GAAP to be reclassified to net income (loss) in its entirety in the same reporting period. For other amounts that are not required under GAAP to be reclassified in their entirety to net income (loss), an entity is required to cross-reference to other disclosures required under GAAP that provide additional detail about those amounts. ASU 2013-02 was effective prospectively for reporting periods beginning after December 15, 2012. We adopted this standard effective January 1, 2013. The adoption of this standard did not have any impact on our consolidated financial statements.

1. The business

        Boingo Wireless, Inc. and its subsidiaries (collectively "we, "us", "our" or "the Company") is a leading global provider of mobile Internet solutions for smartphones, tablet computers, laptops, and other wireless-enabled consumer devices. The Company has more than a million small cell networks for cellular distributed antenna system ("DAS") and Wi-Fi access that reach more than one billion consumers annually. Boingo Wireless, Inc. was incorporated in April 16, 2001 in the State of Delaware. We have a diverse monetization model that enables us to generate revenues from retail sales, wholesale partnerships, and advertising across these small cell networks. Retail products include Wi-Fi subscriptions and day passes that provide access to more than 800,000 commercial hotspots worldwide, and Internet Protocol television ("IPTV") services and residential broadband for military barracks. Wholesale offerings include Wi-Fi roaming, private label Wi-Fi, location based services, and DAS, which are cellular extension networks. Advertising revenue is driven by Wi-Fi sponsorships at airports, hotels, cafes and restaurants, and public spaces. Our customers include some of the world's largest carriers, telecommunications service providers and global consumer brands, as well as Internet savvy consumers on the go and troops stationed at military bases.

• Initial public offering

        On May 3, 2011, our registration statement registering 3,846,800 shares of common stock offered by us and 1,923,200 shares offered by certain selling stockholders was declared effective by the United States Securities and Exchange Commission, and the shares began trading on the NASDAQ Global Market on May 4, 2011 under the symbol "WIFI." The proceeds from the sale of these shares are used primarily for working capital and other general corporate purposes. As a result of the initial public offering ("IPO"), we raised a total of approximately $45,701 in net proceeds after deducting underwriting discounts and commissions of approximately $3,635 and offering expenses of approximately $2,596. In connection with the IPO, all of the shares of our convertible preferred stock were converted into 22,845,764 shares of common stock and all of the warrants to purchase preferred stock were exercised and converted into 20,172 shares of common stock through net-share settlement.

• Reverse stock split

        On April 7, 2011, our board of directors approved a 5 for 1 reverse stock split of our outstanding common stock which was effected on May 3, 2011. Fractional shares were settled in cash totaling approximately $1 for common and preferred stockholders. No fractional shares were settled for option holders, and they were rounded down as a result of the reverse stock split. Shares of common stock underlying outstanding stock options and warrants and shares of our preferred stock and warrants were proportionately reduced and the respective exercise prices were proportionately increased in accordance with the terms of the agreements governing such securities. Shares of common stock reserved for issuance upon the conversion of our convertible preferred stock were proportionately reduced and the respective conversion prices were proportionately increased. All references to shares in the accompanying consolidated financial statements and the notes thereto, including but not limited to the number of shares and per share amounts, unless otherwise noted, have been adjusted to reflect the reverse stock split retroactively. Previously awarded options and warrants to purchase shares of our common and preferred stock have also been retroactively adjusted to reflect the reverse stock split.

        We have a foreign subsidiary in the United Kingdom, which has generated losses since inception resulting in an $644 deferred tax asset with a corresponding valuation allowance as of December 31, 2013. We also have a majority owned foreign subsidiary in Brazil, which has generated losses since inception resulting in a $69 deferred tax assets with a corresponding valuation allowance as of December 31, 2013. Foreign loss before income taxes was $559, $61, and $45 for 2013, 2012, and 2011, respectively.

        Deferred income tax reflects the tax effects of temporary differences that gave rise to significant portions of our deferred tax assets and liabilities and consisted of the following for the years ended December 31, 2013 and December 31, 2012; respectively:

	2013			2012
Deferred tax assets:
Net operating loss carryforwards	$	3,508		$	1,917

Net deferred tax liabilities		(8,891	)		(1,728	)
Net deferred taxes	$	(2,177	)	$	5,460

        In assessing the realizability of deferred tax assets, we consider whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. As of December 31, 2013 and 2012, we had federal net operating loss carryforwards of approximately $20,389 and $15,283, respectively, state net operating loss carryforwards of approximately $37,153 and $29,955, respectively, and foreign net operating loss carryforwards of $3,425 and $1,588, respectively. The federal net operating loss carryforwards will begin to expire in 2025, and our foreign net operating loss carryforwards have an indefinite life. Our state net operating loss carryforwards are principally related to California net operating losses and will begin to expire in 2015. Our ability to utilize certain of our net operating loss carryforwards may be limited in the event that a change in ownership, as defined in the Internal Revenue Code, occurs in the future.

        The following table sets forth the changes in the valuation allowance, for all periods presented:

	Valuation Allowance

Additions charged to operations		2,294
Decrease credited to operations		—
Balance, December 31, 2013	$	3,963

        During the year ended December 31, 2013, we recorded a $2,294 increase in our valuation allowance on our federal deferred tax assets, primarily due to changes in our expectations regarding our ability to realize these deferred tax assets. This resulted from a determination that it was more likely than not that certain federal net deferred tax assets would not be realized. We recently won some significant new contracts for the build out of residential broadband and IPTV networks for troops stationed on military bases that will now require us to make investments and incur losses in advance of experiencing any direct benefit from them including generation of revenues.

        During the year ended December 31, 2011, we recorded a $1,287 release to the valuation allowance on our state net deferred tax assets, due to changes in our expectations regarding our ability to realize these deferred tax assets. This resulted from a determination that it was more likely than not that certain state net deferred tax assets would be realized. The remaining valuation allowance primarily relates to the deferred tax assets for state net operating losses that the Company believes is not more likely than not to be realized before expiration.

        In reaching the determination of the valuation allowance, we have evaluated all significant available positive and negative evidence including, but not limited to, our three year cumulative results, trends in our business, expected future results and the character, amount and expiration periods of our net deferred tax assets. The underlying assumptions we used in forecasting future income required significant judgment and took into account our recent performance.

        During 2013, 2012 and 2011, we realized excess windfall tax benefits of approximately $55, $2,190 and $246, respectively, from stock option exercises. These benefits decreased income taxes payable and were recorded as an increase to additional paid-in capital in the accompanying consolidated balance sheets. In accordance with the reporting requirements under ASC 718, we did not include excess windfall tax benefits resulting from stock option exercises as components of our gross deferred tax assets and corresponding valuation allowance disclosures, as tax attributes related to those windfall tax benefits should not be recognized until they result in a reduction of taxes payable. The tax effected amount of gross unrealized net operating loss carryforwards excluded under ASC 718 was approximately $5,847 at December 31, 2013. When realized, those excess windfall tax benefits are credited to additional paid-in capital.

        We recognized interest and penalties related to income tax matters in income taxes which were not material during the years ended December 31, 2013, 2012, and 2011.

        We identify, evaluate and measure all uncertain tax positions taken or to be taken on tax returns and record liabilities for the amount of these positions that may not be sustained, or may only partially be sustained, upon examination by the relevant taxing authorities. Although we believe that our estimates and judgments were reasonable, actual results may differ from these estimates. Some or all of these judgments are subject to review by the taxing authorities. As of December 31, 2013 and 2012, we had $445 and $392 in uncertain tax positions, respectively, $106 of which is a reduction to deferred tax assets, which is presented net of uncertain tax positions, in the accompanying consolidated balance sheets. We accrue interest and penalties related to unrecognized tax benefits as a component of income taxes. As of December 31, 2013, we have accrued $53 for related interest, net of federal income tax benefits, and penalties recorded in income tax expense on our consolidated statements of operations. There were no significant accrued interest and penalties as of December 31, 2012.

        A reconciliation of our unrecognized tax benefits, excluding interest and penalties, is as follows:

	Uncertain Tax Positions
Balance, December 31, 2012	$	392
Additions for current period tax positions		—
Balance, December 31, 2013	$	392

        Our annual income taxes and the determination of the resulting deferred tax assets and liabilities involve a significant amount of judgment. Our judgments, assumptions and estimates relative to current income taxes take into account current tax laws, their interpretation of current tax laws and possible outcomes of current and future audits conducted by foreign and domestic tax authorities. We operate within federal, state and international taxing jurisdictions and are subject to audit in these jurisdictions. These audits can involve complex issues which may require an extended period of time to resolve. We are subject to taxation in the United States and in various states. Our tax years 2010 and forward are subject to examination by the IRS and our tax years 2007 and forward are subject to examination by material state jurisdictions. However, due to prior year loss carryovers, the IRS and state tax authorities may examine any tax years for which the carryovers are used to offset future taxable income. We are currently subject to examination by the IRS for our 2011 tax year. Although the ultimate outcome is unknown, we believe that any adjustments that may result from examination is not likely to have a material, adverse effect on our consolidated results of operations, financial position or cash flows.

• Capital and operating leases

        We lease space in managed and operated locations, primarily airports, under exclusive long-term, non-cancellable contracts to provide Wi-Fi connectivity and cellular phone access to our DAS network. Minimum rent expense is recorded on a straight-line basis over the term of the lease. Rent expense from our leases for the years ended December 31, 2013, 2012 and 2011 was $20,234, $16,760 and $15,511, respectively.

        We lease equipment, primarily data communication equipment and database software under non-cancellable capital leases that expired in October 2011. The leases were collateralized by the equipment under the lease. Interest expense associated with the capital leases for the years ended December 31, 2013, 2012 and 2011 was $15, $11 and $8, respectively. We also lease office space under non-cancellable operating leases. Rent expense for our leases of office facilities for the years ended December 31, 2013, 2012 and 2011 was $1,227, $1,209 and $1,323, respectively. Included in rent expense for the years ended December 31, 2013, 2012 and 2011 was sublease income of $54, $52 and $32, respectively.

        Future minimum lease obligations under non-cancellable operating and capital leases at December 31, 2013 are as follows:

Years ended December 31,	Capital Leases			Operating Leases and Airport Guarantees
2014	$	662		$	10,819

• Letters of credit

        In October 2013, we entered into a Letter of Credit ("Letter of Credit") Authorization agreement with Silicon Valley Bank ("SVB") for a one year term. The Letter of Credit is irrevocable and serves as a performance guarantee that will allow our customer to draw up to $1,800 if we are in default. There have been no drafts drawn under this Letter of Credit as of December 31, 2013.

• Legal proceedings

        From time to time, we may be subject to claims, suits, investigations and proceedings arising out of the normal course of business. We are not currently a party to any litigation that we believe could have a material adverse effect on our business, financial position, results of operations or cash flows.

• Indemnification

        Indemnification provisions in our third-party service provider agreements provide that we will indemnify, hold harmless, and reimburse the indemnified parties on a case-by-case basis for losses suffered or incurred by the indemnified parties in connection with any claim by any third party as a result of our website, advertising, marketing, payment processing, collection or customer service activities. The maximum potential amount of future payments we could be required to make under these indemnification provisions is undeterminable. We have never paid a claim, nor have we been sued in connection with these indemnification provisions. At December 31, 2013 and 2012, we have not accrued a liability for these guarantees, because the likelihood of incurring a payment obligation in connection with these guarantees is not probable.

• Employment contracts

        We have entered into employment contracts with six of our officers. These contracts generally provide for severance benefits, including salary continuation, if employment is terminated by us for substantial cause or by the officer for convenience. In addition, in order to assure that they would continue to provide independent leadership consistent with our best interests in the event of an actual or threatened change in control, the contract also generally provides for certain protections in the event of such a change in control. These protections include the payment of certain severance benefits, including salary continuation, upon the termination of employment following a change in control.

Total assets	$	39,031	$	44,018	$	83,049

        Our marketable securities utilize Level 2 inputs and consist primarily of corporate securities which include commercial paper and corporate debt instruments including notes issued by foreign or domestic corporations which pay in U.S. dollars and carry a rating of A or better. We have evaluated the various types of securities in our investment portfolio to determine an appropriate fair value hierarchy level based upon trading activity and the observability of market inputs. Due to variations in trading volumes and the lack of quoted market prices in active markets, our fixed maturities are classified as Level 2 securities.

        The fair value of our fixed maturity marketable securities is derived through the use of a third party pricing source or recent reported trades for identical or similar securities, making adjustments through the reporting date based upon available market observable data.

        The Company used the income approach to value the contingent consideration as of December 31, 2013. The contingent consideration used a discounted cash flow method with probability weighted cash flows and a discount rate of 25.0% for Endeka. The contingent consideration used a discount rate of 3.1% for AWG. The following table presents a reconciliation of the beginning and ending amounts related to the fair value of contingent consideration for the Endeka and AWG acquisitions, categorized as Level 3:

• Convertible preferred stock

        Each share of Series A, Series A-2, Series B and Series C convertible preferred stock was immediately convertible, at the holder's option, into shares of common stock based on the formula of the issuance price divided by the conversion price. The conversion price was $3.00 for Series A and B convertible preferred stock, $4.026072935 for Series A-2 convertible preferred stock and $4.95835 for Series C convertible preferred stock. Each share of Series A and Series B convertible preferred stock was convertible into one share of common stock. Series A-2 convertible preferred stock was convertible into shares of common stock as obtained by multiplying the number of shares of the convertible stock by $4.30 and dividing the result by the conversion price of $4.026072935 per share, which approximates a 1 for 1.07 shares of common stock conversion rate. Series C convertible preferred stock was convertible into shares of common stock as obtained by multiplying the number of shares of the convertible stock by $5.95 and dividing the result by the conversion price of $4.95835 per share, which approximates a 1 for 1.2 shares of common stock conversion rate. Conversion of each share of Series A, Series A-2, Series B and Series C convertible preferred stock was automatic upon the completion of our IPO.

        The holders of the Series A, Series A-2, Series B and Series C convertible preferred stock were also entitled to receive cumulative dividends, whether or not earned or declared, out of funds legally available therefore, at the rate of $0.15 per share per annum for the Series A and Series B convertible preferred stock, $0.215 for the Series A-2 convertible preferred stock and $0.2975 for the Series C convertible preferred stock (the "accruing dividends"). Accruing dividends accrued on each share of convertible preferred stock from the date of issuance until the earlier of (i) a liquidation, dissolution or winding up of the company, including an acquisition, consolidation or merger, or the sale of all or substantially all of the assets of the company (a "liquidation event") and (ii) the date of redemption. We accrued dividends in the year ended December 31, 2011, which were accreted in the respective carrying values of the convertible preferred stock before they were converted into common stock.

• Reserve for unissued shares

        At December 31, 2013 and 2012, we are authorized to issue up to 100,000,000 shares of common stock. We are required to reserve and keep available out of our authorized but unissued shares of common stock such number of shares sufficient to effect the exercise of all outstanding common stock warrants, plus shares granted and available for grant under our Amended and Restated 2001 Stock Incentive Plan (the "2001 Plan") and 2011 Equity Incentive Plan (the "2011 Plan").

        The amount of such shares of common stock reserved for these purposes is as follows:

	December 31, 2013		December 31, 2012
	(in thousands)
Outstanding stock options under the 2001 Plan		1,859		2,345
Outstanding stock options under the 2011 Plan		3,096		2,700
Outstanding RSUs under the 2011 Plan		753		—
Shares available for grant under the 2011 Plan		3,259		2,811
Total		8,967		7,856

• Note receivable from stockholder

        During 2002, we granted 290,000 shares of restricted common stock to an officer at the deemed fair value of $0.30 per share in exchange for cash proceeds of approximately $9 and issuance of a partial recourse note ("Note") of approximately $78 payable with an interest rate equal to the applicable federal rate. On January 11, 2011, we forgave the Note and the principal and interest outstanding of $103 was expensed as compensation. Interest accrued on the Note, and was included in interest and other income (expense), net in the accompanying consolidated statements of operations.

• Treasury stock

        On July 29, 2011, we approved the retirement of all 1,256,608 outstanding shares of treasury stock. The treasury stock, at cost, of $4,575 was transferred to additional paid-in capital in the accompanying consolidated statements of convertible preferred stock and stockholder's equity (deficit).

• Common stock warrants

        On June 28, 2011, our 26,322 common stock warrants outstanding were exercised into 21,525 shares of common stock on a net exercise basis.

14. Stock incentive plans

        In March 2011, our board of directors approved the 2011 Plan. The 2011 Plan provides for the grant of incentive and nonstatutory stock options, stock appreciation rights, restricted shares of our common stock, stock units, and performance cash awards. As of January 1^st of each year, the number of shares of common stock reserved for issuance under the 2011 Plan shall automatically be increased by a number equal to the lesser 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) as determined by our board of directors. As of December 31, 2013, 7,108,013 shares of common stock are reserved for issuance. As of December 31, 2013, options to purchase 5,026,486 shares of common stock and 799,289 RSUs have been granted under the 2011 Plan.

        No further awards will be made under our 2001 Plan and it will be terminated. Options outstanding under the 2001 Plan will continue to be governed by their existing terms. As of December 31, 2013, options to purchase 1,858,543 shares of common stock were outstanding under the 2001 Plan.

        The following table summarizes our stock-based compensation expense included in the consolidated statements of operations for 2013, 2012 and 2011:

Total stock-based compensation expense	$	4,506	$	2,735	$	3,423

• Stock option awards

        We grant stock option awards to both employees and non-employee directors. The grant date for these awards is the same as the measurement date. The stock option awards generally vest over a four year service period with 25% vesting when the individual completes 12 months of continuous service and the remaining 75% vesting monthly thereafter. These awards are valued as of the measurement date and the stock-based compensation expense, net of estimated and actual forfeitures, is recognized on a straight-line basis over the requisite service period. A summary of the activity for stock option awards for 2013, 2012 and 2011 is presented below:

        The aggregate intrinsic value in the table above represents the difference between the estimated fair value of our common stock at December 31, 2013 and the option exercise price, multiplied by the number of in-the-money options at December 31, 2013. The intrinsic value changes are based on the estimated fair value of our common stock.

        Stock options to purchase 461,000, 1,899,000 and 1,015,000 shares of our common stock were exercised during the years ended December 31, 2013, 2012 and 2011 for cash proceeds of $614, $2,573 and $1,028, respectively. The total intrinsic value of stock options exercised for the years ended December 31, 2013, 2012 and 2011 was $2,662, $14,901 and $9,754, respectively. We realized $55, $2,190 and $246 of tax benefits for the deductions from stock option exercises during 2013, 2012 and 2011, respectively.

        The weighted average grant date fair value of options granted for the years ended December 31, 2013, 2012 and 2011 was $6.60, $8.10 and $6.68, respectively.

        At December 31, 2013, the total remaining stock-based compensation expense for unvested stock option awards is $7,345, which is expected to be recognized over a weighted average period of 2.95 years.

• Restricted stock unit awards

        During the year ended December 31, 2013, we issued RSUs to executive and non-executive personnel and members of our board of directors. The executive and non-executive RSUs generally vest over a two year period with 50% of the RSUs vesting when the individual completes 12 months of continuous service and the remaining 50% vesting on a quarterly basis thereafter. The board of directors RSUs generally vests over a one year period for existing members and 25% per year over a four year period for new members. A summary of the RSU activity in 2013 is as follows:

	Number of Shares (000's)			Weighted Average Grant Date Fair Value
Nonvested at December 31, 2012		—		$	—
Granted		799		$	6.21
Vested		(6	)	$	6.39
Canceled/forfeited		(40	)	$	6.05
Nonvested at December 31, 2013		753		$	6.22

        The RSUs that vested during the year ended December 31, 2013 resulted from the accelerated vesting for an employee that retired during 2013. At December 31, 2013, the total remaining stock-based compensation expense for unvested RSU awards is $2,750, which is expected to be recognized over a weighted average period of 1.4 years.
