Notes to the Condensed Consolidated Financial Statements

(Unaudited)

(In thousands, except shares and per share amounts)

1. The business

Boingo Wireless, Inc. and its subsidiaries (collectively “we, us or our”) is a leading global provider of mobile Wi-Fi Internet solutions. Our solutions enable individuals to access our extensive global Wi-Fi network with devices such as smartphones, laptops and tablet computers. Boingo Wireless, Inc. was incorporated on April 16, 2001 in the State of Delaware. We have direct customer relationships with users who have purchased our mobile Internet services, and we provide solutions to our partners which include telecom operators, cable companies, technology companies, enterprise software and services companies, and communications companies to allow their millions of users to connect to the mobile Internet through hotspots in our network.

2. Summary of significant accounting policies

Basis of presentation

The accompanying interim unaudited condensed consolidated financial statements and related notes for the three and nine months ended September 30, 2012 and 2011 are unaudited. The unaudited interim condensed consolidated financial information has been prepared with the rules and regulations of the SEC for interim financial information. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles (“GAAP”) in the United States of America (“U.S.”) for complete financial statements. These financial statements should be read in conjunction with the audited consolidated financial statements and the accompanying notes for the year ended December 31, 2011 contained in our annual report on Form 10-K filed with the SEC on April 13, 2012. The unaudited interim condensed consolidated financial statements have been prepared on the same basis as the annual consolidated financial statements and in the opinion of management, reflect all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation of our results of operations for the three and nine months ended September 30, 2012 and 2011, our cash flows for the nine months ended September 30, 2012 and 2011, and our financial position as of September 30, 2012. The year-end balance sheet data was derived from audited consolidated financial statements, but does not include all disclosures required by GAAP. Interim results are not necessarily indicative of the results to be expected for an entire year or any other future year or interim period.

Principles of consolidation

The unaudited condensed consolidated financial statements include our accounts and our majority owned subsidiaries. We consolidate our 70% ownership of Concourse Communications Detroit, LLC and our 70% ownership of Chicago Concourse Development Group, LLC 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. The results of operations for the acquisition of companies accounted for under the purchase method of accounting have been included in the consolidated statements of operations beginning on the closing date of the acquisition. All intercompany balances and transactions have been eliminated in consolidation.

Segment information

We operate as one reportable segment; a service provider of mobile Wi-Fi solutions across our managed and operated network and aggregated network for mobile devices such as laptops, smartphones and tablets. 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.

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 our normal operating cycle. At September 30, 2012 and December 31, 2011, we had $37,219 and $0 in short-term marketable securities, respectively, and no long-term marketable securities.

7

Table of Contents

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 periods 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 nine months ended September 30, 2012, we had no significant realized or unrealized gains or losses from investments in marketable securities classified as available-for-sale.

Revenue recognition

We generate revenue from several sources including: (i) 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, (ii) platform service arrangements with wholesale customers that provide software licensing, network access, and professional services fees and (iii) wholesale customers that are telecom operators under long-term contracts for access to our distributed antenna system (“DAS”) at our managed and operated locations. 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.

Subscription fees from retail customers are paid monthly in advance by charge card and revenue is deferred for the portions of monthly recurring subscription fees collected in advance. Our charge card processor withheld three percent of our sales for future refunds for a period of six months from the month of activity, which was recognized as revenue at the time of sale because the reserve balance was not used to provide refunds to customers. The reserve amount was subject to credit evaluations and biannual reviews. Based on the contract terms with the charge card processor as of November 2011, we are no longer required to withhold sales, and as a result, at September 30, 2012, we had no charge card reserve. 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.

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, which is generally between two to five years. 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 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 wholesale partner arrangement which generally range from five to ten years. 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.

8

Table of Contents

We may provide professional services for initial implementation services for certain platform and DAS arrangements. For our existing arrangements that are accounted for under ASC 605-25, Revenue Recognition - Multiple-Deliverable Revenue Arrangements, we defer recognition of the full arrangement consideration including the initial implementation activities, and recognize all revenue ratably over the wholesale service period, as we do not have evidence of fair value for the undelivered elements in the arrangement. Upon the adoption of ASU 2009-13, Revenue Recognition (Topic 605) — Multiple Deliverable Revenue Arrangements on January 1, 2011, certain of our platform service or DAS arrangements may require the initial implementation services to be accounted for as a separate unit of accounting. For such arrangements entered into or materially modified after January 1, 2011, we allocate arrangement consideration at the inception of the arrangement to all units of accounting based on the relative selling price method. We recognize the revenue associated with any implementation services that qualify for separate units of accounting upon completion of such services and all other revenue will be recognized ratably over the remaining term of the wholesale service agreement.

Advertising and other revenue is recognized when the services are performed.

Revision of prior period financial statements

During the three months ended December 31, 2011, prior period errors were identified relating to accounting for income taxes that primarily resulted from the Company’s improper recording of the following: deferred income taxes on the 2006 acquisition of Concourse Communications Group, LLC, the valuation allowance release, and tax benefits related to stock-based compensation. These errors impacted periods beginning in the year ended December 31, 2006 and subsequent periods through September 30, 2011.

In evaluating whether our previously issued consolidated financial statements were materially misstated, the Company considered the guidance in ASC Topic 250, Accounting Changes and Error Corrections, ASC Topic 250-10-S99-1, Assessing Materiality, and ASC Topic 250-10-S99-2, Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements. We concluded these errors were not material individually or in the aggregate to any of the prior reporting periods, and therefore, amendments of previously filed reports were not required. However, the cumulative error would have been material in the year ended December 31, 2011, if the entire correction was recorded in the fourth quarter of 2011. As such, the revisions for these corrections to the applicable prior periods, including for the three and nine months ended September 30, 2011, are reflected in the financial information herein and will be reflected in future filings containing such financial information.

The prior period unaudited condensed consolidated financial statements for the three and nine months ended September 30, 2011 included in this filing have been revised to reflect the corrections of these tax related errors, the effects of which have been provided in summarized format below.

Recent accounting pronouncements

In September 2011, the FASB issued ASU 2011-08, Intangibles—Goodwill and Other: Testing Goodwill for Impairment (“ASU 2011-08”). This ASU is intended to simplify how entities test goodwill for impairment. It permits an entity 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. The more-likely-than-not threshold is defined as having a likelihood of more than 50%. ASU 2011-08 will be effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. Early adoption is permitted, including for annual and interim goodwill impairment tests performed as of a date before September 15, 2011, if an entity’s financial statements for the most recent annual or interim period have not yet been issued. We perform our impairment tests on December 31st of each year. We do not expect the adoption of this update to have a material impact on our financial position, results of operations or cash flows.

In July 2012, the Intangibles topic was amended to permit an entity to consider qualitative factors to determine whether it is more likely than not that indefinite-lived intangible assets are impaired. If it is determined to be more likely than not that indefinite-lived intangible assets are impaired, then the entity is required to determine the fair value of the indefinite-lived intangible asset and perform the quantitative impairment test by comparing the fair value with the carrying amount. The amendments are effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012. Early adoption is permitted. The amendments are not expected to have a material effect on the Company’s financial statements.

In June 2011, the FASB issued ASU 2011-05, Comprehensive Income: Presentation of Comprehensive Income, which amends current comprehensive income guidance. This ASU eliminates the option to present the components of other comprehensive income (“OCI”) as part of the statement of stockholders’ equity. Instead, it requires entities to report components of comprehensive income in either (1) a continuous statement of comprehensive income or (2) two separate but consecutive statements. Under the two-statement approach, the first statement would include components of net income, which is consistent with the income statement format used today, and the second statement would include components of OCI. The ASU does not change the items that must be reported in OCI. Subsequently, the FASB issued ASU 2011-12, Comprehensive Income — Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05 (“ASU 2011-12”). ASU 2011-12 defers indefinitely the provision within ASU 2011-05 requiring entities to present reclassification adjustments out of accumulated OCI by component in both the income statement and the statement in which OCI is presented. ASU 2011-12 does not change the other provisions instituted within ASU 2011-05. The Company adopted this standard effective January 1, 2012. The adoption of this standard had no material impact on our financial position, results of operations or cash flows as the Company’s comprehensive income currently equals net income.

In May 2011, the FASB issued ASU 2011-04, Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S.GAAP and IFRS, which amends the wording used to describe many of the requirements in GAAP for measuring fair value and disclosing information about fair value measurements. The amendments in this ASU achieve the objectives of developing common fair value measurement and disclosure requirements in U.S. GAAP and International Financial Reporting Standards (“IFRS”) and improving their understandability. Some of the requirements clarify the FASB’s intent about the application of existing fair value measurement requirements while other amendments change a particular principle or requirement for measuring fair value or for disclosing information about fair value measurements.

The amendments in this ASU are effective prospectively for interim and annual periods beginning after December 15, 2011, with no early adoption permitted. The adoption of this standard had no material impact on our financial position, results of operations or cash flows.

3. Acquisition

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 hotels, bars and restaurants, and recreational areas at over 6,000 locations in the U.S. and Canada. In accordance with FASB ASC 805 Business Combinations, we accounted for the acquisition as a business combination and the assets and liabilities of Cloud 9 we acquired are included in our unaudited condensed consolidated financial statements from the date of acquisition.

The following table summarizes the allocation of the purchase price to the acquired tangible and identifiable intangible assets and liabilities assumed based on their fair values at the date of acquisition:

Current assets |  | $ | 899 |
Property, plant and equipment |  | 65 |
Intangible and other assets |  | 1,758 |
Goodwill |  | 1,232 |
Current liabilities |  | (454 | )
Total purchase price |  | $ | 3,500 |

The fair value of the acquired assets and liabilities at the time of the acquisition was estimated at $3,185, net of cash acquired. As the acquired entity is a private company, the fair value was based on significant inputs that are not observable in the market and thus represents a Level 3 measurement as defined in FASB ASC 820, Fair Value Measurements and Disclosures.

The following table summarizes the acquired intangible assets at September 30, 2012:

|  | Weighted- average Remaining Life |  | Gross Carrying Amount |  | Accumulated Amortization |  | Net Book Value |
|  |  |  | (unaudited, in thousands) |
Technology |  | 5 yrs |  | $ | 1,110 |  | $ | 36 |  | $ | 1,074 |
Other |  | 5 to 10 yrs |  | 640 |  | 12 |  | 628 |
Total |  |  |  | $ | 1,750 |  | $ | 48 |  | $ | 1,702 |

The intangibles assets are all definite-lived intangibles and are recognized on a straight-line basis over their weighted average lives of approximately 6.4 years.

The excess of the purchase price over the net tangible and intangible assets acquired resulted in goodwill of $1,232. Goodwill is not deductible for income tax purposes. The acquisition increased goodwill from $25,512 million at December 31, 2011 to $26,744 million at September 30, 2012.

4. Cash and cash equivalents and marketable securities

Cash and cash equivalents, and marketable securities consisted of the following:

|  | September 30, 2012 |  | December 31, 2011 |
Cash and cash equivalents: |  |  |  |  |
Cash |  | $ | 11,587 |  | $ | 12,851 |
Money market accounts |  | 45,763 |  | 81,082 |
Total cash and cash equivalents |  | $ | 57,350 |  | $ | 93,933 |
Short-term marketable securities—available-for-sale: |  |  |  |  |
Marketable securities |  | $ | 37,219 |  | $ | — |
Total short-term marketable securities |  | $ | 37,219 |  | $ | — |

All contractual maturities of marketable securities were less than one year at September 30, 2012. These 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.

For the nine months ended September 30, 2012, and 2011, interest income was $128 and $29, respectively, which is included in interest and other income (expense), net in the accompanying condensed consolidated statements of operations.

5. Property and equipment

Property and equipment consisted of the following:

|  | September 30, 2012 |  | December 31, 2011 |
Leasehold improvements |  | $ | 75,671 |  | $ | 60,030 |
Construction in progress |  | 7,264 |  | 7,059 |
Computer equipment |  | 7,347 |  | 6,674 |
Software |  | 7,213 |  | 5,818 |
Office equipment |  | 411 |  | 400 |
Total property and equipment |  | 97,906 |  | 79,981 |
Less: accumulated depreciation and amortization |  | (51,936 | ) | (40,264 | )

Depreciation and amortization of property and equipment is allocated as follows on the accompanying unaudited condensed consolidated statements of operations:

|  | Three Months Ended September 30, |  | Nine Months Ended September 30, |
|  | 2012 |  | 2011 |  | 2012 |  | 2011 |
Network access |  | $ | 2,704 |  | $ | 2,637 |  | $ | 8,848 |  | $ | 6,295 |
Network operations |  | 687 |  | 664 |  | 2,077 |  | 1,842 |
Development and technology |  | 375 |  | 234 |  | 656 |  | 674 |
General and administrative |  | 32 |  | 20 |  | 91 |  | 83 |
Total depreciation and amortization of property and equipment |  | $ | 3,798 |  | $ | 3,555 |  | $ | 11,672 |  | $ | 8,894 |

6. Fair value measurement

ASC 820, Fair Value Measurements and Disclosures, establishes a three-tiered hierarchy that draws a distinction between market participant assumptions based on (i) quoted prices (unadjusted) in active markets for identical assets and liabilities (Level 1); (ii) inputs other than quoted prices in active markets that are observable either directly or indirectly (Level 2); and (iii) unobservable inputs that require us to use present value and other valuation techniques in the determination of fair value (Level 3). The following table sets forth our financial assets that are measured at fair value on a recurring basis:

At September 30, 2012 |  | Level 1 |  | Level 2 |  | Total |
Assets: |  |  |  |  |  |  |
Cash equivalents |  | $ | 45,763 |  | $ | — |  | $ | 45,763 |
Marketable securities available-for-sale |  | — |  | 37,219 |  | 37,219 |
Total assets |  | $ | 45,763 |  | $ | 37,219 |  | $ | 82,982 |

At December 31, 2011 |  | Level 1 |  | Level 2 |  | Total |
Assets: |  |  |  |  |  |  |
Cash equivalents |  | $ | 81,082 |  | $ | — |  | $ | 81,082 |
Marketable securities available-for-sale |  | — |  | — |  | — |
Total assets |  | $ | 81,082 |  | $ | — |  | $ | 81,082 |

Our marketable securities available-for-sale 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.

12

Table of Contents

The fair value of our fixed maturity marketable securities available-for-sale 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.

7. Accrued expenses and other liabilities

Accrued expenses and other liabilities consisted of the following:

|  | September 30, 2012 |  | December 31, 2011 |
Revenue share |  | 3,982 |  | $ | 3,915 |
Salaries and wages |  | 2,760 |  | 3,934 |
Accrued for construction-in-progress |  | 1,410 |  | 688 |
Accrued partner network |  | 857 |  | 1,274 |
Deferred service usage credits |  | — |  | 634 |
Deferred rent |  | 806 |  | 223 |
Accrued taxes |  | 42 |  | 682 |
Amounts due to non-controlling interests |  | 515 |  | 557 |
Other |  | 577 |  | 852 |
Total accrued expenses and other liabilities |  | $ | 10,949 |  | $ | 12,759 |

8. Income taxes

We calculate our interim income tax provision in accordance with ASC 270, Interim Reporting, and ASC 740, Accounting for Income Taxes. At the end of each interim period, we estimate the annual effective tax rate and apply that rate to our ordinary quarterly earnings. The tax expense or benefit related to significant, unusual, or extraordinary items is recognized in the interim period in which those items occur. In addition, the effect of changes in enacted tax laws, rates, or tax status is recognized in the interim period in which the change occurs.

The computation of the annual estimated effective tax rate at each interim period requires certain estimates and significant judgment, including the expected operating income for the year, projections of the proportion of income earned and taxed in various states, permanent and temporary differences as a result of differences between amounts measured and recognized in accordance with tax laws and financial accounting standards, and the likelihood of recovering deferred tax assets generated in the current year. The accounting estimates used to compute the provision for income taxes may change as new events occur, additional information is obtained, or as the tax environment changes.

During the nine months ended September 30, 2012, we recognized excess windfall tax benefits of $3,364 from stock option exercises. These benefits will decrease income taxes payable for the year ended December 31, 2012, and were recorded as an increase to additional paid-in capital in the accompanying unaudited condensed consolidated balance sheet as of September 30, 2012.

Income tax expense of $2,468 and $1,985 reflects an effective tax rate of 27.6% and 29.0% for the nine months ended September 30, 2012 and 2011, respectively. For the nine months ended September 30, 2012, our effective tax rate differs from the statutory rate primarily due to benefits from disqualifying dispositions of incentive stock options and adjustments relating to our 2011 tax returns. For the nine months ended September 30, 2011, our effective tax rate differs from the statutory rate primarily due to incentive stock options that were recharacterized as nonqualified stock options. Under current tax regulations, we do not receive a tax deduction for the issuance, exercise or disposition of incentive stock options if the employee meets certain holding requirements. If the employee does not meet the holding requirements, a disqualifying disposition occurs, at which time we may receive a tax deduction. We do not record tax benefits related to incentive stock options unless and until a disqualifying disposition is reported. At September 30, 2012, we have net deferred tax assets of $6,869, which includes net operating loss carry-forwards and other losses. As of September 30, 2012, we have recorded no liability for income taxes associated with uncertain tax positions.

We are subject to taxation in the United States and in various states. Our tax years 2007 and forward are subject to examination by the IRS and our tax years 2006 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.

9. Commitments and contingencies

Litigation

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

10. Stock incentive plans

In March 2011, our board of directors approved the 2011 Equity Incentive Plan (“2011 Plan”) under which 5,511,288 shares of common stock are reserved for issuance. The 2011 Plan provides for the grant of incentive and nonstatuatory stock options, stock appreciation rights, restricted shares of our common stock, stock units, and performance cash awards. As of January 1 of each year, the number of shares of common stock reserved for issuance under our stock incentive 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 and (c) as determined by our board of directors.

No further awards will be made under our Amended and Restated 2001Stock Incentive Plan (“2001 Plan”), which terminated pursuant to its term. Options outstanding under the 2001 Plan will continue to be governed by their existing terms.

The weighted average assumptions used for newly issued stock option grants for the nine months ended September 30, 2012 were an expected term of 6.2 years, an expected volatility of 50%, a risk free rate of return of 0.95% and no expected dividends.

We recognized stock-based compensation expense as follows:

|  | Three Months Ended September 30, |  | Nine Months Ended September 30, |
|  | 2012 |  | 2011 |  | 2012 |  | 2011 |
Network operations |  | $ | 117 |  | $ | 186 |  | $ | 227 |  | $ | 297 |
Development and technology |  | (253 | ) | 228 |  | 168 |  | 388 |
Selling and marketing |  | (36 | ) | 264 |  | 366 |  | 438 |
General and administrative |  | 390 |  | 694 |  | 1,402 |  | 1,152 |
Total stock-based compensation |  | $ | 218 |  | 1,372 |  | $ | 2,163 |  | $ | 2,275 |

The $1,154 decrease in stock-based compensation expense for the three months ended September 30, 2012 as compared to the three months ended September 30, 2011, is primarily a result of the reversal of $650 in stock-based compensation expense for unvested options for two senior executives who left the Company.

A summary of the stock option activity under the Plan is as follows:

|  | Number of Options |  | Weighted Average Exercise Price |  | Weighted- Average Remaining Contract Life (years) |  | Aggregate Intrinsic Value |
Outstanding at December 31, 2011 |  | 6,601 |  | $ | 5.50 |  | 7.0 |  | $ | 30,996 |
Granted |  | 1,104 |  | $ | 8.30 |  |  |  |  |
Exercised |  | (1,578 | ) | $ | 1.35 |  |  |  |  |
Cancelled/forfeited |  | (743 | ) | $ | 11.59 |  |  |  |  |
Outstanding at September 30, 2012 |  | 5,384 |  | $ | 6.45 |  | 6.82 |  | $ | 17,891 |
Vested and expected to vest at September 30, 2012 |  | 5,273 |  | $ | 6.31 |  | 6.78 |  | $ | 17,871 |
Exercisable at September 30, 2012 |  | 2,881 |  | $ | 2.69 |  | 5.09 |  | $ | 16,666 |

Overview

Boingo makes it simple to connect to the mobile Internet.

We make it easy, convenient and cost effective for individuals to find and gain access to the mobile Internet through high-speed, high-bandwidth Wi-Fi networks globally. We also manage and operate a distributed antenna system infrastructure, or DAS which is a cellular extension network. Our solution includes easy-to-use software for Wi-Fi enabled devices such as smartphones, laptops and tablet computers, and our sophisticated back-end system infrastructure that detects and enables one-click access to our extensive global Wi-Fi network. Individuals use our solutions to access what we believe is the world’s largest commercial Wi-Fi network, consisting of over 550,000 Wi-Fi locations, or hotspots, in over 100 countries at venues such as airports, hotels, coffee shops, shopping malls, arenas, stadiums and quick service restaurants.

We have direct customer relationships with users who have purchased our mobile Internet services, and we provide solutions to our partners, which include telecom operators, cable companies, technology companies, enterprise software and services companies, and communications companies to allow their millions of users to connect to the mobile Internet through hotspots in our network. As of September 30, 2012, we have grown our subscriber base to 292,000, an increase of 19.7% over the prior year period.

Individuals who are accustomed to the benefits of broadband performance at home and work are seeking the same applications, performance and availability on-the-go, through smartphones, laptops, tablet computers and other devices. We believe that this consumer demand has created a significant market opportunity that we are uniquely positioned to capture.

We generate revenue from individual users, partners and advertisers. Individual users provide approximately half of our revenue by purchasing month-to-month subscription plans that automatically renew, or hotspot specific single-use access to our network. In addition, our partners pay us usage-based network access and software licensing fees to allow their customers access to our network. We also generate revenue from telecom operators that pay us build-out fees and access fees so that their cellular customers may use our distributed antenna system or DAS in locations where we also manage and operate the Wi-Fi network. We also generate revenue from advertisers that seek to reach our users with sponsored access, display advertising, and other promotional programs.

Table of Contents

We install, manage and operate wireless network infrastructure to provide Wi-Fi services at our managed and operated hotspots, where we generally have exclusive multi-year agreements.

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. Despite spending billions of dollars every year to expand their networks, network and telecom operators still face capacity-strained networks. Innovations in broadband technologies such as 3G and 4G will not be sufficient to relieve the strain on networks. We believe we are the leading global provider of commercial mobile Wi-Fi Internet solutions. Key elements of our strategy to extend that lead are to:

· extend our network footprint via our neutral-host business model;

· expand our partner relationships;

· increase the installed base of our software;

· grow our business internationally and

· drive new revenue sources.

Reconciliation of Non-GAAP Financial Measures

We define Adjusted EBITDA as net income (loss) attributable to common stockholders plus depreciation and amortization of property and equipment, accretion of convertible preferred stock, income taxes, amortization of other intangible assets, stock-based compensation expense, non-controlling interests’ expense and interest and other (expense) income, 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-GAAP financial measures to supplement their GAAP results; and

· it is useful to exclude non-cash charges, such as accretion of convertible preferred stock, depreciation and amortization of property and equipment and asset impairment, amortization of other intangible assets and stock-based compensation, and non-core operational charges such as acquisition-related expense, 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 acquisitions, 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.

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 income attributable to common stockholders.

The $2.8 million increase in depreciation and amortization expense of property and equipment for the nine months ended September 30, 2012 as compared to the nine months ended September 30, 2011 are due to a one-time DAS build-out project of $1.3 million and $1.5 million from other DAS build-out projects for the nine months ended.

The $1.2 million decrease in stock-based compensation expense for the three months ended September 30, 2012 as compared to the three months ended September 30, 2011, is primarily a result of the reversal of $0.7 million in stock-based compensation expense for unvested options for two senior executives who left the Company.

There are three key metrics that we use to monitor results and activity in the business as follows:

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 and/or sponsorship and/or promotion fees. We count each connect as a single connect regardless of how many times the individual accesses the network at a given venue during their 24 hour period. This measure is an indicator of paid activity throughout our network.

Total revenue. Total revenue increased $1.3 million or 5.4%, for the three months ended September 30, 2012, as compared to the three months ended September 30, 2011.

Retail subscription. Retail subscription revenue increased $1.2 million, or 15.9%, for the three months ended September 30, 2012, as compared to the three months ended September 30, 2011, due to a 19.7% increase in subscribers. This increase in subscribers was partially offset by a decrease in our revenue per subscriber from the mix of lower-priced smartphone and tablet subscriptions compared to unlimited subscriptions.

Retail single-use. Retail single-use revenue decreased $0.5 million, or 13.8%, for the three months ended September 30, 2012, as compared to the three months ended September 30, 2011. The decrease in single-use revenue was due to the increase in new customers that opted for subscriptions and the impact of increased sponsorship promotions in the quarter.

Wholesale. Wholesale revenue decreased $0.4 million, or 3.2%, for the three months ended September 30, 2012, as compared to the three months ended September 30, 2011, due to a decrease of $0.4 million from DAS access and usage fees and $0.2 million from a decrease in partner usage-based fees which were partially offset by an increase of $0.2 million in new DAS build-out projects in our managed and operated locations.

Advertising and other. Advertising and other revenue increased $1.1 million, or 75.0% for the three months ended September 30, 2012, as compared to the three months ended September 30, 2011, due primarily to $0.8 million in revenues earned from the assets acquired from Cloud 9 Wireless, Inc., and a $0.3 increase in other sponsorship revenues.

The Adjusted EBITDA increase was due primarily to greater net income of $3.1 million, $1.3 million of depreciation from a one-time DAS build-out project, $1.5 million of depreciation from other DAS build-out projects, $0.5 million from income tax expense and $0.1 million in non-controlling interest. These increases were partially offset by the accretion of convertible preferred stock of $1.6 million which was an add-back in the prior year nine month period, $0.6 million in amortization expense, $0.5 million in other expenses and a $0.1 million decrease in stock-based compensation.

Liquidity and Capital Resources

We have financed our operations primarily through cash provided by operating activities and, prior to our initial public offering (“IPO”), private placements of preferred equity securities and common stock. Our primary sources of liquidity as of September 30, 2012 consisted of $57.3 million of cash and cash equivalents and $37.2 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 the first nine months of 2012 were $15.8 million; with $12.6 million for DAS build-out projects which were reimbursed by the telecom operators.

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, however, 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 may enter into acquisitions of complementary businesses, 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 nine months ended September 30:

|  | 2012 |  | 2011 |
|  | (unaudited) |
|  | (in thousands) |
Net cash provided by operating activities |  | $ | 17,234 |  | $ | 19,986 |
Net cash used in investing activities |  | (56,173 | ) | (12,346 | )
Net cash provided by financing activities |  | 2,356 |  | 45,493 |

Net Cash Provided by Operating Activities

For the nine months ended September 30, 2012, we generated $17.2 million of net cash from operating activities which consisted of net income including non-controlling interests expense of $6.5 million, adjusted for non-cash charges for depreciation and amortization of property and equipment of $11.7 million, stock-based compensation expense of $2.1 million, amortization of intangible assets of $0.7 million, offset by a decrease in excess tax benefits of $1.0 million, decrease in deferred taxes of $0.4 million, and a greater use of working capital of $2.4 million. The increase in depreciation and amortization of property and equipment was primarily due to our significant investment in DAS networks since the nine months ended September 30, 2011. The $(2.4) million use of cash from working capital compared to the $3.2 million source of cash from working capital in nine months ended September 30, 2011, was due to $(0.9) million in accounts payable, $(4.0) million in accrued expenses and other liabilities, $(5.1) million in accounts receivable, offset by $1.7 million in prepaids and other assets and deferred revenue of $2.7 million.

Net Cash Used in Investing Activities

For the nine months ended September 30, 2012, we used $56.2 million in investing activities as compared to $12.3 million for the nine months ended September 30, 2011. Our investing activities in 2012 included net purchases of $37.2 million of short-term marketable securities, purchases of $15.8 million of property and equipment, primarily related to $13.2 million in DAS build-out projects in our managed and operated locations, and the purchase of acquired assets of $3.2 million.

Net Cash Provided by Financing Activities

For the nine months ended September 30, 2012, we generated $2.4 million in financing activities. This was primarily due to a $2.1 million increase in proceeds from the exercise of stock options and a $1.0 million non-cash source from excess tax benefits for stock-based compensation expense, partially offset by payments to non-controlling interests of $0.6 million and payments of capital leases of $0.2 million. For the nine months ended September 30, 2011, cash provided by financing activities primarily consisted of proceeds from our initial public offering.

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.

Critical Accounting Policies and Estimates

There have been no material changes to our critical accounting policies and estimates from the information provided for the year ended December 31, 2011 in “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” included in our annual report on Form 10-K filed by us with the SEC on April 13, 2012.

Recently Issued Accounting Standards

See Note 2 to our unaudited condensed consolidated financial statements in Part I, Item 1 of this report for a description of recently issued accounting standards, including our expected dates of adoption and estimated effects on our results of operations and financial condition.

Item 3. Quantitative and Qualitative Disclosure about Market Risk

Market risk represents the risk of loss that may impact our financial position due to adverse changes in financial market prices and rates. Our market risk exposure is primarily a result of fluctuations in interest rates. We do not hold or issue financial instruments for trading purposes.

We had cash and cash equivalents of $57.3 million and $37.2 million of marketable securities at September 30, 2012 and $93.9 million of cash and cash equivalents at December 31, 2011. We held these amounts primarily in cash or money market funds.

We hold cash and cash equivalents for working capital purposes. We do not have material exposure to market risk with respect to investments classified as cash equivalents, as these consist primarily of highly liquid investments purchased with original maturities of three months or less. Our marketable securities are also highly liquid and classified as short-term because they are expected to be realized within one year. We do not use derivative financial instruments for speculative or trading purposes. We may, however, adopt specific hedging strategies in the future.

Item 4. Controls and Procedures

Disclosure Controls and Procedures. We carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness, as of September 30, 2012, of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934). Based on this assessment, as of September 30, 2012, the Company’s Chief Executive Officer and Chief Financial Officer have concluded that the Company’s disclosure controls and procedures were not effective at the reasonable assurance level because of the unremediated material weakness in our internal control over financial reporting related to income taxes described below. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis.

Table of Contents

Notwithstanding the unremeditated material weakness described below, management believes that the condensed consolidated financial statements in this Form 10-Q fairly present, in all material respects, our financial position, results of operations and cash flows for the interim and annual periods presented in accordance with generally accepted accounting principles.

As previously disclosed in our annual report on Form 10-K for the year ended December 31, 2011, we did not have adequate design or operation of controls that provide reasonable assurance that the accounting for income taxes and related disclosures were prepared in accordance with generally accepted accounting principles. Specifically, we did not have sufficient review and control with respect to the complete and accurate recording of deferred income tax assets and related valuation allowance, accrued taxes and income tax expense. This control deficiency contributed to adjustments and revisions to prior year financial statements amounts that are reflected in the condensed consolidated financial statements for the three and nine months ended September 30, 2011. Accordingly, our management determined that this control deficiency constituted a material weakness. Because of this material weakness, management concluded that the Company did not maintain effective internal control over financial reporting as of September 30, 2011.

Remediation Plan

As previously reported in our annual report on Form 10-K for the year ended December 31, 2011, our management implemented a number of remediation steps to address the material weakness in internal control surrounding the accounting for income taxes described above. Specifically, the following have been implemented:

· Re-evaluated the design of income tax accounting processes and controls and implement new and improved processes and controls, accordingly;

· Retained an experienced professional accounting firm to assist with the income tax provision and to provide a detailed review of the tax implications of complex transactions;

· Hired additional personnel with tax knowledge and experience to provide a detailed assessment of the calculation and supporting details of the accounts, to strengthen the internal review process and to assist in the implementation and management of improved processes and controls.

Management is committed to a strong internal control environment and believes that, when fully implemented and tested, the measures described above will improve our internal control over financial reporting. We will continue to assess the effectiveness of our remediation efforts in connection with our future assessments of the effectiveness of internal control over financial reporting.

Changes in Internal Control over Financial Reporting. Other than the remediation steps described above, there were no changes in our internal control over financial reporting during the quarter ended September 30, 2012 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
