Basis of Presentation— - The accompanying unaudited condensed consolidated financial statements and notes have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and in conformity with Article 10 of RegulationS-X promulgated under the Securities Act of 1933, as amended (the “Securities Act”). Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements and should be read in conjunction with our annual audited consolidated financial statements and the notes thereto included in our Annual Report on Form10-K for the year ended December 31, ~~2016~~2017 as filed with the Securities and Exchange Commission (“SEC”) on February ~~27, 2017~~22, 2018 (the ~~“2016~~“201710-K”). These unaudited condensed consolidated financial statements reflect, in the opinion of management, all material adjustments (which include normal recurring adjustments) necessary to fairly state, in all material respects, our financial position, results of operations and cash flows for the periods presented.

The results of operations and cash flows for the ~~nine~~three and six month ~~period~~periods ended ~~September~~June 30, ~~2017~~2018 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, ~~2017.~~2018.

We have one class of common stock outstanding as of ~~September~~June 30, ~~2017~~2018 and December 31, ~~2016.~~2017.

Reclassifications - To conform with the current year presentation, certain amounts in our unaudited condensed consolidated statement of cash flows for the six month period ended June 30, 2017 have been reclassified. Specifically, accrued airline revenue share of $27 thousand and current deferred rent of $181 thousand have been combined with accrued liabilities andnon-current deferred rent of $284 thousand has been combined with othernon-current assets and liabilities. Additionally, warranty reserves are now separately stated in its own line, which was included within accrued liabilities previously.

Transition to airline-directed model - The accounting treatment for one of our airline agreements transitioned from our turnkey model to our airline-directed model in January 2018 due to specific provisions elected by the airline that resulted in the transfer of control of the previously installed connectivity equipment. Upon transition to the airline-directed model, the net book value of all previously delivered equipment classified within property and equipment was reclassified to cost of equipment revenue. Additionally, the unamortized proceeds previously received for equipment and classified within current andnon-current deferred airborne lease incentives were eliminated and included as part of estimated contract value, which was then allocated amongst the various performance obligations under the agreement. The value allocated to previously delivered equipment was immediately recognized as equipment revenue in our unaudited condensed consolidated financial statements; refer to Note 3, “Revenue Recognition,” for additional disclosures relating to the allocation of consideration among identified performance obligations. For amounts recognized in equipment revenue that were in excess of the amounts billed, we recorded current andnon-current contract assets included within prepaid expenses and other current assets and othernon-current assets, respectively; refer to Note 3, “Revenue Recognition,” for additional details. In connection with the transition of this airline agreement to the airline-directed model, we also established warranty reserves related to previously sold equipment that are still under a warranty period, which is included

within accrued liabilities. See Note 8, “Warranties,” for additional information. This transition from the turnkey model to the airline-directed model occurred on January 4, 2018 and the total financial statement effect on our unaudited condensed consolidated balance sheet and unaudited condensed consolidated statement of operations was as follows (in thousands):

During the second quarter 2018, we identified an additional $2.2 million of property and equipment, net that should have been included in the transition adjustments as of January 1, 2018. The schedule above reflects the additional adjustment.

Use of Estimates— - The preparation of financial statements in conformity with ~~GAAP~~accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of ~~revenue~~revenues and expenses during the reporting period. On an ongoing basis, management evaluates the significant estimates and bases such estimates on historical experience and on various other assumptions believed to be reasonable under the circumstances. However, actual results could differ materially from those estimates.

On January 1, 2018, we ~~reassess~~adopted Accounting Standards Codification Topic 606,Revenue From Contracts With Customers (“ASC 606”) using the ~~useful life of the affected equipment.~~modified retrospective method. As a result, we ~~shorten~~recognized the ~~useful lives~~cumulative effect of initially applying ASC 606 as an adjustment to the opening balance of retained earnings as of January 1, 2018. Our historical financial statements have not been restated and continue to be reported under the revenue accounting standard in effect for those periods.

Prior to the adoption of ASC 606, equipment revenue (and related cost) under some of ourCA-NA andCA-ROW segment contracts was deferred and recognized over the life of the ~~affected~~contract as the equipment and connectivity services did not meet the requirements to be ~~consistent~~treated as separate units of accounting. Under ASC 606, these same equipment transactions qualify as standalone performance obligations and, therefore, equipment revenue (and related cost) is recognized upon acceptance by our airline customers. Adoption of the new standard did not materially affect the amount or timing of equipment revenue recognized from our BA segment. Our service revenue across all segments continues to be recognized as the services are provided to customers.

In conjunction with the ~~estimated upgrade date~~adoption of ASC 606, we also adopted Accounting Standard Codification Subtopic340-40,Other Assets and Deferred Costs – Contracts with Customers(“ASC340-40”), which requires the capitalization of costs incurred to obtain or ~~aircraft decommissioning date, as applicable.

Costs associated with our turnkey contracts are not eligible for capitalization under ASC340-40 and will continue to these events resulted in increases in depreciation expense of $8.6 million and $14.9 million, respectively, in the three and nine month periods ended September 30, 2017 and increases in the amortization of deferred airborne lease incentives, which reduced our cost of service revenue, of $1.3 million and $3.5 million, respectively, in the three and nine month periods ended September 30, 2017. As a result, net loss per basic and fully diluted share increased by $0.09 and $0.14, respectively, for the three and nine month periods ended September 30, 2017.

~~2. Recent Accounting Pronouncements~~The cumulative effect of the adoption of ASC 606 and ASC340-40 to our unaudited condensed consolidated balance sheet as of January 1, 2018 was as follows (in thousands):

During the ~~Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”)2014-09,~~~~Revenue From Contracts With Customers~~ ~~(“ASU2014-09”).~~ This pronouncement outlines a single comprehensive model to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance. The core principlesecond quarter 2018, we identified an additional $2.3 million of ~~ASU2014-09~~ is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Additionally, the FASB issued several amendments to the standard, including clarification on accounting for licenses of intellectual property and ~~identifying performance obligations. This new guidance is effective for annual reporting periods beginning after December 15, 2017, including interim periods within~~equipment, net that should have been recorded to accumulated deficit in the ~~annual reporting periods; we will adopt this guidance~~transition adjustments as of January 1, 2018. ~~We are continuing to evaluate our revenue contracts under~~The schedule above reflects the new guidance. Based on our preliminary understanding of the impact the adoption of this standard will have on our financial statements, we reassessed and now plan to adopt the standard using the modified retrospective method. Under the modified retrospective method, revenue and expenses that would have been recognized in the future will be recorded to equity as a cumulative adjustment at the date of adoption. While we are continuing to evaluate the impact of the adoption of this guidance on our consolidated financial statements, we currently believe that the measurement and timing of recognition of revenue and related costs from certain of our customer contracts will be impacted in the following ways, primarily from our Airline Directed contracts in~~CA-NA~~ ~~andCA-ROW~~ ~~(cash flows and cash and cash equivalents will not be impacted):~~additional adjustment.

~~Under the current revenue recognition standard, the sale ofCA-NA~~ ~~andCA-ROW~~ ~~airborne connectivity equipment does not meet all of the requirements~~See Note 3, “Revenue Recognition,” for ~~being recognized as a separate unit of accounting, resulting in the deferral of equipment revenue (and the related equipment cost) over the life of the contract. Under ASU2014-09,~~ we have concluded that the sale of airborne connectivity equipment for Airline Directed arrangements will represent a separate performance obligation as it is both capable of being distinct and distinct within the context of the arrangement. As such, the recognition of all airborne equipment revenue and related costs will be accelerated and recognized upon installation.

Our contracts with customers generate service revenue that varies based on usage of our service. Under the current revenue recognition standard, these revenues are recognized as services are provided. Under ASU~~2014-09,~~ our preliminary conclusion is that we will be required to use a variable consideration model which requires us to estimate (and constrain) variable service revenue, and allocate total contract consideration among all performance obligations. Additionally, estimates used in the recognition of revenue under the new standard will be updated as new facts and circumstances warrant, which may cause differences in the trend of revenue recognition as compared to that reported under the current standard.

We have assessed the treatment of costs to obtain or fulfill a contract with a customer, including costs to obtain Supplemental Type Certificates (“STCs”) issued by the FAA that are required to install our equipment on aircraft. Such costs are expensed as incurred under the current standard. Under ASU~~2014-09,~~ we have concluded that under our Airline Directed model these costs require capitalization and subsequent amortization over the anticipated service period. Conversely, STC costs incurred in connection with our airline partners operating under our Turnkey model are not subject to the same guidance and will continue to be expensed as incurred under ASU~~2014-09.~~

~~Penalties are recorded under the current standard when incurred. Under ASU2014-09,~~ ~~anticipated penalties will be accounted for as a reduction of revenue when or at the time the related performance obligation is satisfied.~~

~~The impact upon adoption of ASU2014-09~~ is subject to change based on new contracts or contractual amendments executed prior to the date of adoption, including contractual amendments that change and arrangement from a Turnkey model to an Airline Directed model. Such changes could have a significant effect on the transition adjustment recorded upon adoption of the new standard.additional information.

ASU2018-07 is effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. Early adoption is permitted. We are currently assessing the impact of ASU2018-07 on our consolidated financial statements and related disclosures.

Our revenue is primarily earned from providing connectivity and entertainment services and through sales of equipment. Additionally, to a lesser extent, we earn revenue from providing ancillary services, including installation and Connected Aircraft Services (“CAS”).

Recognition of revenue as we satisfy the performance obligations

ForCA-NA andCA-ROW, pursuant to contractual agreements with our airline partners, we place our equipment on commercial aircraft operated by the airlines in order to deliver our service to passengers on the aircraft. We currently have two types of commercial airline arrangements: turnkey and airline-directed. Under the airline-directed model, we have transferred control of the equipment to the airline and therefore the airline is our customer in these transactions. Under the turnkey model, we have not transferred control of our equipment to our airline partner and, as a result, the airline passenger is deemed to be our customer. Transactions with our airline partners under the turnkey model are accounted for as an operating lease of space on an aircraft. See Note 11, “Leases,” for additional information on the turnkey model.

CA-NA andCA-ROW revenue consists of service revenue primarily derived from connectivity services, and, to a lesser extent, from entertainment services and CAS. Connectivity is provided to our customers using both our ATG and satellite technologies.

As noted above, under the airline-directed model, the airline is our customer and we earn service revenue as connectivity services are consumed directly by the airline or indirectly by passengers.

Under the turnkey model, passenger connectivity revenue is generated by services paid for by passengers, airlines and third parties.

Passenger paid revenue representspoint-of-sale sessions (which may be flight-based, time-based, multiple individual session packages (“multi-pack”) and subscriptions). Flight-based, time-based and multi-pack revenue is recognized when the sessions are used. Subscription revenue is recognized evenly throughout the subscription period, regardless of the number of times the customer uses the network.

Third party and airline paid revenue is generated by sales of connectivity services to airlines or third parties in sponsorship, wholesale, enterprise and roaming arrangements. Sponsorship revenue is recognized over the sponsorship term. Revenue from wholesale, enterprise and roaming arrangements is recognized as sessions are used by the passenger.

Entertainment revenue consists of entertainment services we provide to the airline for use by its passengers. Revenue is recognized as the services are provided to the airline.

CAS includes, among other things, real-time credit card transaction processing, electronic flight bags and real-time weather information. Revenue is recognized as the service is provided.

BA service revenue primarily consists of monthly subscription and usage fees paid by aircraft owners and operators for telecommunication, data, andin-flight entertainment services. Revenue is recognized as the services are provided to the customer.

Equipment revenue primarily consists of the sale of ATG and satellite connectivity equipment and the sale of entertainment equipment.CA-NA andCA-ROW recognize equipment revenue upon acceptance by our airline customers. BA recognizes equipment revenue when the equipment is shipped to OEMs and dealers.

Equipment revenue also includes revenue generated by the installation of the connectivity or entertainment equipment on commercial aircraft, which is recognized when the installation is complete.

OurCA-NA andCA-ROW airline-directed contracts contain multiple performance obligations, which primarily include the sale of equipment, installation services, connectivity services and entertainment services. For these contracts, we account for each distinct good or service as a separate performance obligation. We allocate the contract’s transaction price to each performance obligation using the relative standalone selling price, which is based on the actual selling price for any good or service sold separately to a similar class of customer, if available. To the extent a good or service is not sold separately, we use our best estimate of the standalone selling price and maximize the use of observable inputs. The primary method we use to estimate the standalone selling price is the expected cost-plus margin approach.

The contractual consideration used for allocation purposes includes connectivity and entertainment services, which may be based on a fixed monthly fee per aircraft or a variable fee based on the volume of connectivity activity, or a combination of both. Examples of variable consideration within our contracts include megabyte overages andpay-per-use sessions. We constrain our estimates to reduce the probability of a significant revenue reversal in future periods, allocate such variable consideration to the identified performance obligations and recognize revenue in the period the services are provided. Our estimates are based on historical experience, anticipated future performance, market conditions and our best judgment at the time.

A significant change in one or more of these estimates could affect our estimated contract value, and we regularly review and update our estimates and recognize adjustments under the cumulativecatch-up method. Any adjustment under this method is recorded as a cumulative adjustment in the period identified and revenue for future periods is recognized using the new adjusted estimate.

As of June 30, 2018, the aggregate amount of the transaction price in our contracts allocated to the remaining unsatisfied performance obligations is approximately $966 million, most of which relates to our commercial aviation contracts. Approximately $187 million represents future equipment revenue that is expected to be recognized within the next one to three years. The remaining $779 million primarily represents connectivity and entertainment service revenues which are recognized as services are provided, which is expected to occur through the remaining term of the contract (approximately5-10 years). We have excluded from this amount: all variable consideration derived from our connectivity or entertainment services that is allocated entirely to our performance of obligations related to such services; consideration from contracts that have an original duration of one year or less; revenue from passenger service on airlines operating under the turnkey model; and revenue from contracts that have been executed but under which have not yet met the accounting definition of a contract since the airline has not yet determined which products in our portfolio it wishes to select, and, as a result we are unable to determine which products and services will be transferred to the customer.

The following table presents our revenue disaggregated by category(in thousands):

Our current andnon-current deferred revenue balances totaled $62.3 million and $61.1 million as of June 30, 2018, and January 1, 2018, respectively. Deferred revenue includes, among other things, equipment, multi-packs, subscriptions and sponsorships activities.

Our current andnon-current contract asset balances totaled $44.4 million and $5.1 million as of June 30, 2018 and January 1, 2018, respectively. Contract assets represents the aggregate amount of revenue recognized in excess of billings for our airline-directed contracts.

Our STC balances were $13.6 million and $7.6 million as of June 30, 2018, and January 1, 2018, respectively. We recognized $0.2 million and $0.4 million, respectively, of deferred STC costs as part of our engineering, design and development costs in our unaudited condensed consolidated statement of operations during the three and six month periods ended June 30, 2018. As noted above, STC costs for our airline-directed contracts are capitalized and expensed on a straight-line basis over the life of the contract.

The following table presents the post adoption impact of ASC 606 on our unaudited condensed consolidated balance sheet and the statement of operations(in thousands):

Basic and diluted net loss per share have been calculated using the weighted average number of common shares outstanding for the period. The shares of common stock effectively repurchased in connection with the Forward Transactions (as defined and described in Note 8,9, “Long-Term Debt and Other Liabilities”) are considered participating securities requiring thetwo-class method to calculate basic and diluted earnings per share. Net earnings in future periods will be allocated between common shares and participating securities. In periods of a net loss, the shares associated with the Forward Transactions will not receive an allocation of losses, as the counterparties to the Forward Transactions are not required to fund losses. Accordingly, the calculation of weighted average shares outstanding as of ~~September~~June 30, ~~2017~~2018 and ~~2016~~2017 excludes approximately 7.2 million shares that will be repurchased as a result of the Forward Transactions.

As a result of the net loss for the three and ~~nine~~six month periods ended ~~September~~June 30, ~~2017~~2018 and ~~2016,~~2017, all of the outstanding shares of common stock underlying stock options, deferred stock units and restricted stock units were excluded from the computation of diluted shares outstanding because they were anti-dilutive.

The following table sets forth the computation of basic and diluted earnings per share for the three and ~~nine~~six month periods ended ~~September~~June 30, ~~2017~~2018 and ~~2016;~~2017; however, because of the undistributed losses, the shares of common stock associated with the Forward Transactions are excluded from the computation of basic earnings per share in ~~2017~~2018 and ~~2016~~2017 as undistributed losses are not allocated to these shares (in thousands, except per share amounts):

Intangible assets with indefinite lives and goodwill are not amortized, but are reviewed for impairment at least annually or whenever events or circumstances indicate the carrying value of the asset may not be recoverable. We perform our annual impairment tests of our indefinite-lived intangible assets and goodwill during the fourth quarter of each fiscal year. We also reevaluate the useful life of ~~the~~ indefinite-lived intangible assets each reporting period to determine whether events and circumstances continue to support an indefinite useful life. The results of our annual indefinite-lived intangible assets and goodwill impairment assessments in the fourth quarter of ~~2016~~2017 indicated no impairment.

Senior Secured Notes– On June 14, 2016 (the “Issue Date”), Gogo Intermediate Holdings LLC (“GIH”) (a wholly owned subsidiary of Gogo Inc.) and Gogo Finance Co. Inc. (a wholly owned subsidiary of GIH) (the“Co-Issuer” and, together with GIH, the “Issuers”), issued $525 million aggregate principal amount of 12.500% senior secured notes due 2022 (the “Original Senior Secured Notes”) under an Indenture, dated as of June 14, 2016 (the “Original Indenture”), among the Issuers, us, as guarantor, certain subsidiaries of GIH, as guarantors (the “Subsidiary Guarantors” and, together with us, the “Guarantors”), and U.S. Bank National Association, as trustee (in such capacity, the “Trustee”) and as collateral agent (in such capacity, the “Collateral Agent”). On January 3, 2017, the Issuers issued $65 million aggregate principal amount of additional 12.500% senior secured notes due 2022 (the “January 2017 Additional Notes”). The January 2017 Additional Notes were issued at a price equal to 108% of their face value resulting in gross proceeds of $70.2 million. On September 20, 2017, the Issuers, the Guarantors and the Trustee entered into the first supplemental indenture (the “Supplemental Indenture” and, together with the Original Indenture, the “Indenture”) to modify certain covenants, as discussed below. On September 25, 2017, the Issuers issued $100 million aggregate principal amount of additional 12.500% senior secured notes due 2022 (the “September 2017 Additional Notes”). The September 2017 Additional Notes were issued at a price equal to 113% of their face value resulting in gross proceeds of $113.0 million. Additionally, we received approximately $2.9 million for interest that accrued from July 1, 2017 through September 24, 2017, which ~~will be~~was paid ~~out when we make~~in our ~~next~~January 2018 interest ~~payment in January 2018.~~payment. We refer to the Original Senior Secured Notes, the January 2017 Additional Notes and the September 2017 Additional Notes collectively as the “Senior Secured Notes.”

As noted above, on September 20, 2017, the Issuers, the Guarantors and the Trustee entered into the Supplemental Indenture to (i) increase the amount of additional secured indebtedness under Credit Facilities (as defined in the Indenture) that may be incurred by the Issuer and its Restricted Subsidiaries (as defined in the Indenture) under the Indenture by $100 million (from $75 million to $175 million in aggregate principal amount), (ii) permit the Issuer and its Restricted Subsidiaries to incur additional secured indebtedness in connection with vendor financing arrangements not to exceed $50 million in aggregate principal amount at any time outstanding and (iii) permit the Issuer and its Restricted Subsidiaries to make additional dividends or distributions to Gogo in an aggregate amount of up to $15 million during any twelve-month period to pay interest on any indebtedness or preferred stock with a maturity later than July 1, 2022. The Supplemental Indenture became effective immediately upon execution, following our receipt of consents from holders of a majority of the outstanding principal amount of the Existing Notes (excluding Existing Notes held by the Issuers or any affiliates of the Issuers) to the Supplemental Indenture and amendments to the collateral agency agreement governing the Senior Secured Notes (the ~~“Consent”~~“Consent Solicitation”). In connection with the Consent Solicitation, GIH paid $1.4 million in fees (“Consent Fees”) to holders of Existing Notes who validly ~~offered~~tendered (and did not revoke) their consents prior to the expiration of the ~~Consent.~~Consent Solicitation.

As of ~~September~~June 30, ~~2017~~2018 and December 31, ~~2016,~~2017, the outstanding principal amount of the Senior Secured Notes was $690.0 million and ~~$525.0~~$690.0 million, ~~respectively. The~~respectively, the unamortized debt premium and Consent ~~fees~~Fees were ~~$16.3~~$14.1 million ~~as of September 30, 2017~~and $15.5 million, respectively, and the net carrying amount was ~~$706.3~~$704.1 million ~~as of September 30, 2017. The net carrying amount was $525.0~~and $705.5 million, ~~as of December 31, 2016.~~respectively.

Interest on the Senior Secured Notes accrues at the rate of 12.500% per annum and is payable semi-annually in arrears on January 1 and July 1, ~~and January 1, commencing~~interest payments commenced on January 1, 2017 (other than the January 2017 Additional Notes, for which interest payments commenced on July 1, 2017, and the September 2017 Additional Notes, for which interest payments ~~will commence~~commenced on January 1, 2018). The Senior Secured Notes mature on July 1, 2022. The January 2017 Additional Notes and September 2017 Additional Notes have the same terms as the Original Senior Secured Notes, except with respect to the issue date and issue price, and are treated as a single series for all purposes under the Indenture and the security documents that govern the Senior Secured Notes.

We paid approximately $11.4 million, $2.0 million and $2.5 million, respectively, of aggregate origination fees and financing costs related to the issuance of the Original Senior Secured Notes, the January 2017 Additional Notes and the September 2017 Additional Notes, which have been accounted for as deferred financing costs. Additionally, as noted above, we paid approximately $1.4 million of Consent ~~fees,~~Fees, which partially offset the net carrying value of the Senior Secured Notes. The deferred financing costs on our unaudited condensed consolidated balance sheet are being amortized over the contractual term of the Senior Secured Notes using the effective interest method. Total amortization expense was ~~$0.5~~$0.7 million and ~~$1.6~~$1.3 million, respectively, for the three and ~~nine~~six month periods ended ~~September~~June 30, ~~2017,~~2018, and ~~$0.4~~$0.6 million and ~~$0.5~~$1.1 million, respectively, for the prior year periods. As of ~~September~~June 30, ~~2017~~2018 and December 31, ~~2016,~~2017, the balance of unamortized deferred financing costs related to the Senior Secured Notes was ~~$13.2~~$11.3 million and ~~$11.2~~$12.6 million, respectively, and is included as a reduction to long-term debt in our unaudited condensed consolidated balance sheet. See Note 9,10, “Interest ~~Costs”~~Costs,” for additional information.

~~Notes to Unaudited Condensed Consolidated Financial Statements – (Continued)~~

The Senior Secured Notes are the senior secured indebtedness of the Issuers and are:

effectively senior to all of the Issuers’ existing and future senior unsecured indebtedness and the Issuers’ indebtedness secured on a junior priority basis by the same collateral securing the Senior Secured Notes, if any, in each case to the extent of the value of the collateral securing the Senior Secured Notes;

effectively senior in right of payment to all of the Issuers’ future indebtedness that is subordinated in right of payment to the Senior Secured Notes;

effectively equal in right of payment with the Issuers’ existing and future (i) unsecured indebtedness that is not subordinated in right of payment to the Senior Secured Notes and (ii) indebtedness secured on a junior priority basis by the same collateral securing the Senior Secured Notes, if any, in each case to the extent of any insufficiency in the collateral securing the Senior Secured Notes;

structurally senior to all of our existing and future indebtedness, including our Convertible Notes (as defined below); and

structurally subordinated to all of the indebtedness and other liabilities of anynon-Guarantors (other than the Issuers).

The Senior Secured Notes are guaranteed, on a senior secured basis, by us and all of GIH’s existing and future domestic restricted subsidiaries (other than theCo-Issuer), subject to certain exceptions. The Issuers’ obligations under the Senior Secured Notes are not guaranteed by Gogo International Holdings LLC, a subsidiary of ours that holds no material assets other than equity interests in our foreign subsidiaries. Each guarantee is a senior secured obligation of such Guarantor and is:

effectively senior to all of such Guarantor’s existing and future senior unsecured indebtedness and such Guarantor’s indebtedness secured on a junior priority basis by the same collateral, if any, securing the guarantee of such Guarantor, in each case to the extent of the value of the collateral securing such guarantee;

effectively senior in right of payment to all of such Guarantor’s future indebtedness that is subordinated in right of payment to such Guarantor’s guarantee;

effectively equal in right of payment with all of such Guarantor’s existing and future (i) unsecured indebtedness that is not subordinated in right of payment to such Guarantor’s guarantee, and (ii) indebtedness secured on a junior priority basis by the same collateral, if any, securing the guarantee of such Guarantor, in each case to the extent of any insufficiency in the collateral securing such guarantee; and

structurally subordinated to all indebtedness and other liabilities of anynon-Guarantor subsidiary of such Guarantor (excluding, in the case of our guarantee, the Issuers).

The Senior Secured Notes and the related guarantees are secured by first-priority liens, subject to permitted liens, on substantially all of the Issuers’ and the Guarantors’ assets, except for certain excluded assets, including pledged equity interests of the Issuers and all of our existing and future domestic restricted subsidiaries guaranteeing the Senior Secured Notes.

The security interests in certain collateral may be released without the consent of holders of the Senior Secured Notes, if such collateral is disposed of in a transaction that complies with the Indenture and related security agreements. In addition, under certain circumstances, we and the Guarantors have the right to transfer certain intellectual property assets that on the Issue Date constitute collateral securing the Senior Secured Notes or the guarantees to a restricted subsidiary organized under the laws of Switzerland, resulting in the release of such collateral without consent of the holders of the Senior Secured Notes.

On or after July 1, 2019, the Issuers may, at their option, at any time or from time to time, redeem any of the Senior Secured Notes in whole or in part. The Senior Secured Notes will be redeemable at the following redemption prices (expressed in percentages of principal amount), plus accrued and unpaid interest, if any, to (but not including) the redemption date (subject to the right of holders of record on the relevant regular record date on or prior to the redemption date to receive interest due on an interest payment date), if redeemed during the twelve-month period commencing on July 1 of the following years:

~~Notes to Unaudited Condensed Consolidated Financial Statements – (Continued)~~

In addition, at any time prior to July 1, 2019, the Issuers may redeem up to 35% of the aggregate principal amount of the Senior Secured Notes with the proceeds of certain equity offerings at a redemption price of 112.500% of the principal amount redeemed, plus accrued and unpaid interest, if any, to (but not including) the date of redemption;provided, however, that Senior Secured Notes representing at least 65% of the principal amount of the Senior Secured Notes remain outstanding immediately after each such redemption.

The Issuers may redeem the Senior Secured Notes, in whole or in part, at any time prior to July 1, 2019, at a redemption price equal to 100% of the principal amount of the Senior Secured Notes redeemed plus the make-whole premium set forth in the Indenture as of, and accrued and unpaid interest, if any, to (but not including) the applicable redemption date.

The Indenture contains covenants that, among other things, limit the ability of the Issuers and the Subsidiary Guarantors and, in certain circumstances, our ability, to: incur additional indebtedness; pay dividends, redeem stock or make other distributions; make investments; create restrictions on the ability of our restricted subsidiaries to pay dividends to the Issuers or make other intercompany transfers; create liens; transfer or sell assets; merge or consolidate; and enter into certain transactions with the Issuers’ affiliates, including us. Most of these covenants will cease to apply if, and for as long as, the Senior Secured Notes have investment grade ratings from both Moody’s Investment Services, Inc. and Standard & Poor’s.

If we or the Issuers undergo specific types of change of control prior to July 1, 2022, GIH is required to make an offer to repurchase for cash all of the Senior Secured Notes at a repurchase price equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to (but not including) the payment date.

The Indenture provides for events of default, which, if any of them occur, would permit or require the principal, premium, if any, and interest on all of the then outstanding Senior Secured Notes issued under the Indenture to be due and payable immediately. As of ~~September~~June 30, ~~2017,~~2018, no event of default had occurred.

Convertible Notes– On March 3, 2015, we issued $340.0 million aggregate principal amount of 3.75% Convertible Senior Notes due 2020 (the “Convertible Notes”) in a private offering to qualified institutional buyers, pursuant to Rule 144A under the Securities Act. We granted an option to the initial purchasers to purchase up to an additional $60.0 million aggregate principal amount of Convertible Notes to cover over-allotments, of which $21.9 million was subsequently exercised during March 2015, resulting in a total issuance of $361.9 million aggregate principal amount of Convertible Notes. The Convertible Notes mature on March 1, 2020, unless earlier repurchased or converted into shares of our common stock under certain circumstances described below. Upon maturity, we have the option to settle our obligation through cash, shares of common stock, or a combination of cash and shares of common stock. We pay interest on the Convertible Notes semi-annually in arrears on March 1 and September 1 of each year. Interest payments began on September 1, 2015.

The $361.9 million of proceeds received from the issuance of the Convertible Notes was initially allocated between long-term debt (the liability component) at $261.9 million and additionalpaid-in-capital (the equity component) at $100.0 million, within the consolidated balance sheet. The fair value of the liability component was measured using rates determined for similar debt instruments without a conversion feature. The carrying amount of the equity component, representing the conversion option, was determined by deducting the fair value of the liability component from the aggregate face value of the Convertible Notes. If we or the note holders elect not to settle the debt through conversion, we must settle the Convertible Notes at face value. Therefore, the liability component will be accreted up to the face value of the Convertible Notes, which will result in additionalnon-cash interest expense being recognized in the unaudited condensed consolidated statements of operations through the Convertible Notes maturity date (see Note 9,10, “Interest Costs” for additional information). The effective interest rate on the Convertible Notes, including accretion of the notes to par and debt issuance cost amortization, was approximately 11.5%. The equity component will not be remeasured as long as it continues to meet the conditions for equity classification.

As of ~~September~~June 30, ~~2017~~2018 and December 31, ~~2016,~~2017, the outstanding principal on the Convertible Notes was $361.9 million, the unamortized debt discount was ~~$55.4~~$39.8 million and ~~$69.9~~$50.4 million, respectively, and the net carrying amount of the liability component was ~~$306.5~~$322.1 million and ~~$292.0~~$311.5 million, respectively.

~~Notes to Unaudited Condensed Consolidated Financial Statements – (Continued)~~

We incurred approximately $10.4 million of issuance costs related to the issuance of the Convertible Notes of which $7.5 million and $2.9 million were recorded toas deferred financing costs and additionalpaid-in capital, respectively, in proportion to the allocation of the proceeds of the Convertible Notes. The $7.5 million recorded as deferred financing costs on our ~~unaudited condensed~~ consolidated balance sheet is being amortized over the term of the Convertible Notes using the effective interest method. Total amortization expense of the deferred financing costs was $0.4 million and ~~$1.1~~$0.8 million, respectively, for the three and ~~nine months~~six month periods ended ~~September~~June 30, ~~2017,~~2018, and ~~$0.4~~$0.3 million and ~~$1.0~~$0.7 million, ~~respective,~~respectively, for the prior year periods. Amortization expense is included in interest expense in the unaudited condensed consolidated statements of operations. As of ~~September~~June 30, ~~2017~~2018 and December 31, ~~2016,~~2017, the balance of unamortized deferred financing costs related to the Convertible Notes was ~~$4.0~~$2.8 million and ~~$5.1~~$3.6 million, respectively, and is included as a reduction to long-term debt in our unaudited condensed consolidated balance sheets. See Note 9,10, “Interest Costs” for additional information.

The Convertible Notes had an initial conversion rate of 41.9274 common shares per $1,000 principal amount of Convertible Notes, which is equivalent to an initial conversion price of approximately $23.85 per share of our common stock. Upon conversion, we currently expect to deliver cash up to the principal amount of the Convertible Notes then outstanding. With respect to any conversion value in excess of the principal amount, we currently expect to deliver shares of our common stock. We may elect to deliver cash in lieu of all or a portion of such shares. The shares of common stock subject to conversion are excluded from diluted earnings per share calculations under theif-converted method as their impact is anti-dilutive.

Holders may convert the Convertible Notes, at their option, in multiples of $1,000 principal amount at any time prior to December 1, 2019, but only in the following circumstances:

during any fiscal quarter beginning after the fiscal quarter ended June 30, 2015, if the last reported sale price of our common stock for at least 20 trading days (whether or not consecutive) during the last 30 consecutive trading days of the immediately preceding fiscal quarter is greater than or equal to 130% of the conversion price of the Convertible Notes on each applicable trading day;

during the five business day period following any five consecutive trading day period in which the trading price for the Convertible Notes is less than 98% of the product of the last reported sale price of our common stock and the conversion rate for the Convertible Notes on each such trading day; or

upon the occurrence of specified corporate events.

None of the above events allowing for conversion prior to December 1, 2019 occurred during the three and ~~nine~~six month periods ended ~~September~~June 30, 2018 or the year ended December 31, 2017. Regardless of whether any of the foregoing circumstances occurs, a holder may convert its Convertible Notes, in multiples of $1,000 principal amount, at any time on or after December 1, 2019 until maturity.

In addition, if we undergo a fundamental change (as defined in the indenture governing the Convertible Notes), holders may, subject to certain conditions, require us to repurchase their Convertible Notes for cash at a price equal to 100% of the principal amount of the Convertible Notes to be purchased, plus any accrued and unpaid interest. In addition, if specific corporate events occur prior to the maturity date, we will increase the conversion rate for a holder who elects to convert its Convertible Notes in connection with such a corporate event in certain circumstances.

In connection with the issuance of the Convertible Notes, we paid approximately $140 million to enter into prepaid forward stock repurchase transactions (the “Forward Transactions”) with certain financial institutions (the “Forward Counterparties”), pursuant to which we purchased approximately 7.2 million shares of common stock for settlement on or around the March 1, 2020 maturity date for the Convertible Notes, subject to the ability of each Forward Counterparty to elect to settle all or a portion of its Forward Transactions early. As a result of the Forward Transactions, total shareholders’ equity within our unaudited condensed consolidated balance sheet was reduced by approximately $140 million. Approximately 7.2 million shares of common stock that will be effectively repurchased through the Forward Transactions are treated as retired shares for basic and diluted EPS purposes although they remain legally outstanding.

~~Amended and Restated Senior Term Facility~~–On July 30, 2014, GIH, Gogo Business Aviation LLC, f/k/a Aircell Business Aviation Services LLC (“GBA”), and Gogo LLC, as borrowers (collectively, the “Borrowers”), entered into an Amendment and Restatement Agreement (the “Amendment”) to the Credit Agreement dated as of June 21, 2012 and amended on April 4, 2013 (the “Amended Senior Term Facility”) among the Borrowers, the lenders named therein, and Morgan Stanley Senior Funding, Inc., as Administrative Agent and Collateral Agent. We refer to the Amendment and the Amended Senior Term Facility collectively as the “Amended and Restated Senior Term Facility.”

On June 14, 2016, the outstanding principal balance of $287.7 million, together with accrued and unpaid interest, was paid in full, and the Amended and Restated Senior Term Facility was terminated in accordance with its terms on such date (subject to the survival of provisions expressly stated therein to survive the termination thereof). Additionally, we paid the voluntary prepayment premium of 3.0%, or $8.6 million, and wrote off all of the remaining unamortized deferred financing costs of $6.8 million. Both of these items are included in loss on extinguishment of debt in our unaudited condensed consolidated financial statements. See Note 6, “Long-Term Debt and Other Liabilities,” in our 2016~~10-K~~ ~~for additional information on the Amended and Restated Senior Term Facility.~~

We paid $22.2 million of loan origination fees and financing costs related to the Amended and Restated Senior Term Facility, all but $4.1 million of which were accounted for as deferred financing costs. Total amortization expense of the deferred financing costs was $1.4 million for the nine month period ended September 30, 2016. Amortization expense is included in interest expense in the unaudited condensed consolidated statements of operations. As noted above, deferred financing costs related to the Amended and Restated Senior Term Facility were written off as of June 14, 2016.

Restricted Cash - Our restricted cash balances were ~~$7.4~~$6.9 million and ~~$7.9~~$7.4 million, respectively, as of ~~September~~June 30, ~~2017~~2018 and December 31, ~~2016~~2017 and primarily consist of letters of credit. Certain of the letters of credit require us to maintain restricted cash accounts in a similar amount, and are issued for the benefit of the landlords at our current office locations in Chicago, IL, Bensenville, IL and Broomfield, CO.

We capitalize a portion of our interest on funds borrowed during the active construction period of major capital projects. Capitalized interest is added to the cost of the underlying assets and amortized over the useful lives of the assets.

The following is a summary of our interest costs for the three and ~~nine~~six month periods ended ~~September~~June 30, ~~2017~~2018 and ~~2016~~2017(in thousands):

Arrangements with Commercial Airlines— Pursuant to contractual agreements with our airline partners, we place our equipment on commercial aircraft operated by the airlines for the purpose of delivering ~~the Gogo~~our service to passengers on the aircraft. There are currently two types of commercial airline arrangements: ~~Turnkey~~turnkey and ~~Airline Directed.~~

~~Notes to Unaudited Condensed Consolidated Financial Statements – (Continued)~~

airline-directed. See Note 3, “Revenue Recognition,” for additional information on airline-directed arrangements.

Under the ~~Turnkey~~turnkey model, we account for equipment transactions as operating leases of space for our equipment on the aircraft. We may be responsible for the costs of installing and/or deinstalling the equipment. ~~The majority of~~Under the turnkey model, the equipment transactions involve the transfer of legal title but do not meet sales recognition for accounting purposes because the risks and rewards of ownership are not fully transferred due to our continuing involvement with the equipment, the length of the term of our agreements with the airlines, and restrictions in the agreements regarding the airlines’ use of the equipment. Under the ~~Turnkey~~turnkey model, we refer to ~~our relationship with~~ the airline as a ~~“partner”.~~“partner.”

Under the ~~Turnkey~~turnkey model, the assets are recorded as airborne equipment on our unaudited condensed consolidated balance sheets, as noted in Note 5,6, “Composition of Certain Balance Sheet Accounts.” Any upfront equipment payments are accounted for as lease incentives and recorded as deferred airborne lease incentives on our unaudited condensed consolidated balance sheets and are recognized as a reduction of the cost of service revenue on a straight-line basis over the term of the agreement with the airline. We recognized ~~$10.1~~$7.5 million and ~~$28.1~~$15.1 million, respectively, for the three and ~~nine~~six month periods ended ~~September~~June 30, ~~2017,~~2018 and ~~$7.8~~$8.6 million and ~~$20.7~~$18.0 million, respectively, for the prior year periods as a reduction to our cost of service revenue in our unaudited condensed consolidated statements of operations. As of ~~September~~June 30, ~~2017,~~2018, deferred airborne lease incentives of ~~$39.1~~$27.2 million and ~~$121.6~~$128.3 million, respectively, are included in current andnon-current liabilities in our unaudited condensed consolidated balance sheet. As of December 31, ~~2016,~~2017, deferred airborne lease incentives of ~~$36.3~~$42.1 million and ~~$135.9~~$142.9 million, respectively, are included in current andnon-current liabilities in our unaudited condensed consolidated balance sheet. The decrease in our deferred airborne lease incentives ~~is due primarily~~and the amortization of the deferred airborne lease incentives relate to the accounting impact of the transition ~~in the accounting treatment for~~of one of our airline agreements ~~from a Turnkey model in~~to the ~~prior year period to an Airline Directed model in the first quarter~~airline-directed model. See Note 1, “Basis of ~~2017 due to specific provisions elected by the airline.~~Presentation,” for additional information.

Under the ~~Turnkey~~turnkey model, the revenue share paid to our airline partners represents operating lease payments. They are deemed to be contingent rental payments, as the payments due to each airline are based on a percentage of ourCA-NA andCA-ROW service revenue generated from that airline’s passengers, which is unknown until realized. Therefore, we cannot estimate the lease payments due to an airline at the commencement of our contract with such airline. This rental expense is included in cost of service revenue and is partially offset by the amortization of the deferred airborne lease incentives discussed above. Such rental expenses totaled a net charge of ~~$7.7~~$6.7 million and ~~$26.9~~$13.1 million, respectively, for the three and ~~nine~~six month periods ended ~~September~~June 30, ~~2017,~~2018 and ~~$10.1~~$10.2 million and ~~$32.3~~$19.1 million, respectively, for the prior year periods. The decrease in rental expense was due to the transition of one of our airline agreements to the airline-directed model. See Note 1, “Basis of Presentation,” for additional information.

A contract with one of our airline partners requires us to provide the airline partner with a cash rebate of $1.8 million in June 2018.

~~Under~~ We intend to make the Airline Directed model, which we have historically used on a limited basis, equipment transactions qualify for sale treatment due to the specific provisions of the agreement. When all the recognition conditions are met for the equipment, the sale is recognized as equipment revenue. When equipment and services are not separable, equipment revenue is deferred and recognized over the service period. Under the Airline Directed model, we refer to our relationship with the airline as a “customer”. For more information see Note 2, “Summary of Significant Accounting Policies” in our 2016~~10-K.~~2018 payment shortly.

Leases and Cell Site Contracts— We have lease agreements relating to certain facilities and equipment, which are considered operating leases. Rent expense for such operating leases was $3.0 million and ~~$9.0~~$6.1 million, respectively, for the three and ~~nine~~six month periods ended ~~September~~June 30, ~~2017,~~2018 and $3.0 million and ~~$8.9~~$6.0 million, respectively, for the prior year periods. Additionally, we have operating leases with wireless service providers for tower space and base station capacity on a volume usage basis (“cell site leases”), some of which provide for minimum annual payments. Our cell site leases generally provide for an initial noncancelable term with various renewal options.

Annual future minimum obligations for operating leases for each of the next five years and thereafter, other than the arrangements we have with our commercial airline partners, as of ~~September~~June 30, ~~2017,~~2018, are as follows (in thousands):

Equipment Leases – We lease certain computer and network equipment under capital leases, for which interest has been imputed with annual interest rates in an approximate range of 8% to 14%. As of ~~September~~June 30, ~~2017~~2018 and December 31, ~~2016~~2017 the computer equipment leases were classified as part of office equipment, furniture, and fixtures and other in our unaudited condensed consolidated balance sheet at a gross cost of ~~$5.1~~$5.3 million and ~~$3.9~~$5.0 million, respectively. As of ~~September~~June 30, ~~2017~~2018 and December 31, ~~2016,~~2017, the network equipment leases were classified as part of network equipment in our unaudited condensed consolidated balance sheet at a gross cost of $7.5 million and $7.5 million, respectively. Annual future minimum obligations under capital leases for each of the next five years and thereafter, as of ~~September~~June 30, ~~2017,~~2018, are as follows (in thousands):

The ~~$3.6~~$2.0 million present value of net minimum lease payments as of ~~September~~June 30, ~~2017~~2018 has a current portion of ~~$2.1~~$1.4 million included in the current portion of long-term debt and capital leases and anon-current portion of ~~$1.5~~$0.6 million included in othernon-current liabilities.

Contractual Commitments - We have agreements with vendors to provide us with transponder and teleport satellite services. These agreements vary in length and amount and as of ~~September~~June 30, ~~2017~~2018 commit us to purchase transponder and teleport satellite services totaling approximately ~~$21.4~~$43.8 million in ~~2017 (October~~2018 (July 1 through December 31), ~~$75.6 million in 2018, $81.9~~$92.7 million in 2019, ~~$86.2~~$90.4 million in 2020, ~~$75.9~~$77.9 million in 2021, $74.4 million in 2022 and ~~$303.0~~$228.1 million thereafter.

We have agreements with various vendors under which we have remaining commitments to purchase satellite-based systems, certifications and development services. Such commitments will become payable as we receive the equipment or certifications, or as development services are provided.

Damages and ~~Penalties—~~Penalties -We have entered into a number of agreements with our airline partners that require us to provide a credit or pay penalties or liquidated damages to our airline partners if we are unable to install our equipment on aircraft by specified timelines or fail to comply with service level commitments. The maximum amount of future credits or payments we could be required to make under these agreements is uncertain because the amount of future credits or payments is based on certain variable inputs.

~~Notes to Unaudited Condensed Consolidated Financial Statements – (Continued)~~

Indemnifications and Guarantees - In accordance with Delaware law, we indemnify our officers and directors for certain events or occurrences while the officer or director is, or was, serving at our request in such capacity. The maximum potential amount of future payments we could be required to make under this indemnification is uncertain and may be unlimited, depending upon circumstances. However, our Directors’ and Officers’ insurance does provide coverage for certain of these losses.

In the ordinary course of business we may occasionally enter into agreements pursuant to which we may be obligated to pay for the failure of performance of others, such as the use of corporate credit cards issued to employees. Based on historical experience, we believe that the risk of sustaining any material loss related to such guarantees is remote.

We have entered into a number of agreements, including our agreements with commercial airlines, pursuant to which we indemnify the other party for losses and expenses suffered or incurred in connection with any patent, copyright, or trademark infringement or misappropriation claim asserted by a third party with respect to our equipment or services. The maximum potential amount of future payments we could be required to make under these indemnification agreements is uncertain and is typically not limited by the terms of the agreements.

~~12.~~Linksmart Litigation - On April 20, 2018, Linksmart Wireless Technology, LLC filed suit against us and eight of our airline partners in the U.S. District Court for the Central District of California alleging that our redirection server and login portal infringe a patent owned by the plaintiff. We are required under our contracts with these airlines to indemnify them for defense costs and any liabilities resulting from the suit. Given the very early stage of this litigation, we are unable to assess the merits of the claim, and the outcome of this matter is inherently uncertain.

under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended, and Rule10b-5 promulgated thereunder, alleging misrepresentations or omissions by us purporting to relate to our 2Ku antenna’s reliability and installation and remediation costs. The plaintiffs seek to recover from us and the individual defendants an unspecified amount of damages. We believe that the claims are without merit and intend to defend them vigorously. In accordance with Delaware law, we will indemnify the individual named defendants for their defense costs and any damages they incur in connection with the suit. We have filed a claim with the issuer of our Directors’ and Officers’ insurance policy with respect to this suit. No amounts have been accrued for any potential losses under this matter, as we cannot reasonably predict the outcome of the litigation or any potential losses.

A three-tier fair value hierarchy has been established which prioritizes the inputs used in measuring fair value. These tiers include:

Our financial assets and liabilities that are disclosed but not measured at fair value include the Senior Secured Notes and the Convertible Notes, which are reflected on the unaudited condensed consolidated balance sheet at cost. The fair value measurements are classified as Level 2 within the fair value hierarchy since they are based on quoted market prices of our instruments in markets that are not active. We estimated the fair value of the Senior Secured Notes and Convertible Notes by calculating the upfront cash payment a market participant would require to assume these obligations. The upfront cash payment used in the calculations of fair value on our ~~September~~June 30, ~~2017~~2018 unaudited condensed consolidated balance sheet, excluding any issuance costs, is the amount that a market participant would be willing to lend at ~~September~~June 30, ~~2017~~2018 to an entity with a credit rating similar to ours and achieve sufficient cash inflows to cover the scheduled cash outflows under the Senior Secured Notes and the Convertible Notes. The calculated fair value of our Convertible Notes is highly correlated to our stock price and as a result significant changes to our stock price could have a significant impact on the calculated fair value of our Convertible Notes.

The fair value and carrying value of long-term debt as of ~~September~~June 30, ~~2017~~2018 and December 31, ~~2016~~2017 were as follows(in thousands):

~~Notes to Unaudited Condensed Consolidated Financial Statements – (Continued)~~

We haveheld-to-maturity financial instruments where carrying value approximates fair value. There were no fair value adjustments to these financial instruments during ~~2017~~the three and ~~2016.~~six month periods ended June 30, 2018 and 2017.

The effective income tax rates for the three and ~~nine~~six month periods ended ~~September~~June 30, ~~2017 was~~2018 were (0.2%) and 5.4%, respectively, as compared with (0.8%) and (0.7%~~), respectively, and (1.4%) and (1.0%~~), respectively, for the prior year periods. ~~Income~~An income tax ~~expense~~benefit was recorded for the six month period ended June 30, 2018 resulting from a reduction in ~~each period was similar, with differences inpre-tax~~ ~~income causing~~our valuation allowance of approximately $4.0 million due to the ~~change in~~application of provisions of H.R. 1, commonly known as the ~~effective~~Tax Cuts and Jobs Act, to our evaluation of our deferred tax ~~rate. The difference between our effective tax rates and the U.S. federal statutory rate of 35% for~~assets. For the three and ~~nine month periods~~six months ended ~~September~~June 30, 2017, ~~and 2016~~our income tax expense was not significant primarily due to the recording of a valuation allowance against our net deferred tax assets.

We are subject to income taxation in the United States, various states within the United States, Canada, Switzerland, Japan, Mexico, Brazil, Singapore, the United Kingdom, Hong Kong, Australia, China, India, France, Germany and ~~Germany.~~the Netherlands. With few exceptions, as of ~~September~~June 30, ~~2017,~~2018, we are no longer subject to U.S. federal, state, local or foreign examinations by tax authorities for years before ~~2013.~~2014.

We record penalties and interest relating to uncertain tax positions in the income tax provision line item in the unaudited condensed consolidated statement of operations. No penalties or interest related to uncertain tax positions were recorded for the three and ~~nine~~six month periods ended ~~September~~June 30, ~~2017~~2018 and ~~2016.~~2017. As of ~~September~~June 30, ~~2017~~2018 and December 31, ~~2016,~~2017, we did not have a liability recorded for interest or potential penalties.

We do not expect a change in the unrecognized tax benefits within the next 12 months.

We operate our business through three operating segments: Commercial Aviation North America, or“CA-NA”, Commercial Aviation Rest of World, or“CA-ROW,” and Business Aviation, or ~~“BA”.~~“BA.” See Note 1, “Basis of Presentation,” for further information regarding our segments.

The accounting policies of the operating segments are the same as those described in Note 2, “Summary of Significant Accounting Policies,” in our ~~2016~~201710-K. Intercompany transactions between segments are excluded as they are not included in management’s performance review of the segments. ~~We currently do not generate a material amount~~For the three and six months ended June 30, 2018 and 2017, our foreign revenue accounts for less than 10% of ~~foreign~~our consolidated revenue. We do not segregate assets between segments for internal reporting. Therefore, asset-related information has not been presented. We do not disclose assets outside of the United States as ~~these~~they totaled less than 10% of our unaudited condensed consolidated assets ~~are not material~~ as of ~~September~~June 30, ~~2017~~2018 and December 31, ~~2016.~~2017. For our airborne assets, we consider only those assets installed in aircraft associated with international commercial airline partners to be owned outside of the United States.

Management evaluates performance and allocates resources to each segment based on segment profit (loss), which is calculated internally as net income (loss) attributable to common stock before interest expense, interest income, income taxes, depreciation and amortization, certainnon-cash ~~charges~~items (including amortization of deferred airborne lease incentives, stock-based compensation expense, amortization of STC costs and ~~adjustment~~the accounting impact of the transition to ~~deferred financing costs)~~the airline-directed model) and other income (expense). Segment profit (loss) is a measure of performance reported to the chief operating decision maker for purposes of making decisions about allocating resources to the segments and evaluating segment performance. In addition, segment profit (loss) is included herein in conformity with ASC280-10,Segment Reporting. Management believes that segment profit (loss) provides useful information for analyzing and evaluating the underlying operating results of each segment. However, segment profit (loss) should not be considered in isolation or as a substitute for net income (loss) attributable to common stock or other measures of financial performance prepared in accordance with GAAP. Additionally, our computation of segment profit (loss) may not be comparable to other similarly titled measures computed by other companies.

A reconciliation of segment profit (loss) to the relevant consolidated amounts is as follows (in thousands):

Major Customers and Airline Partnerships— Under the turnkey model, we refer to the airline as a “partner”, and under the airline-directed model, we refer to the airline as a “customer.”

During the three and ~~nine~~six month periods ended ~~September~~June 30, 2017 and 2016, no customer accounted for more than 10% of our consolidated revenue. One airline partner, under the Turnkey model, accounted for approximately 19% and 18% of consolidated accounts receivable as of September 30, 2017 and December 31, 2016, respectively. Two customers, under the Airline Directed model, collectively2018, American Airlines accounted for approximately 22% and 29% of consolidated ~~accounts receivable as of September 30, 2017~~revenue, respectively, while no other customer accounted for more than 10% of consolidated revenue during the prior year periods. Revenue earned from American Airlines for the six month period ended June 30, 2018 included $45.4 million of equipment revenue recognized due to its transition to the airline-directed model. See Note 1, “Basis of Presentation,” for additional information. Revenue earned from passengers on aircraft operated by American Airlines, which was under the turnkey model during the three and six month periods ended June 30, 2017, accounted for approximately 22% of consolidated revenue during such periods.

Revenue earned from passengers on aircraft operated by Delta Air Lines, which is under the turnkey model, accounted for approximately 23% and 22% of consolidated revenue, respectively, for the three and six month periods ended June 30, 2018 and 26% during both prior year periods.

One customer accounted for approximately 14% and 15%, respectively, of consolidated accounts receivable as of June 30, 2018 and December 31, ~~2016.~~

Stock-Based Compensation —As of ~~September~~June 30, ~~2017,~~2018, we had three stock-based employee compensation plans (“Stock Plans”). See Note 11, “Stock-Based Compensation,” in our ~~2016~~201710-K for further information regarding these plans. Most of our equity grants are awarded on an annual basis. ~~The annual grants occurred in the first quarter of 2017 whereas they had occurred in the second quarter in prior years.~~

For the ~~nine~~six month period ended ~~September~~June 30, ~~2017,~~2018, options to purchase ~~1,992,595~~2,362,236 shares of common stock (of which ~~527,850~~642,462 are options that contain a market condition, in addition to the time-based vesting requirements) were granted, options to purchase ~~48,662~~2,500 shares of common stock were exercised, options to purchase ~~315,140~~560,347 (of which ~~33,620~~286,615 options contain a market condition) shares of common stock were forfeited, and options to purchase ~~265,024~~573,478 shares of common stock expired.

For the six month period ended June 30, 2018, 141,000 shares of common stock were issued under the employee stock purchase plan.

The following is a summary of our stock-based compensation expense by operating expense line in the unaudited condensed consolidated statements of operations(in thousands):

401(k) Plan — Under our 401(k) plan, all employees who are eligible to participate, are entitled to maketax-deferred contributions, subject to Internal Revenue Service limitations. We match 100% of the employee’s first 4% of contributions made, subject to annual limitations.

Research and development costs are reported as a component of engineering, design and development expenses in our unaudited condensed consolidated statements of operations.

On July 17, 2012, Industry Canada issued to our Canadian subsidiary a subordinate license that allows us to use the Canadian ATG spectrum of which SkySurf Canada Communications Inc. (“SkySurf”) is the primary licensee. On July 24, 2012 we entered into a subordinate license agreement (the “License Agreement”) with SkySurf and on August 14, 2012 the agreement commenced. The License Agreement provides for our exclusive rights to use SkySurf’s ATG spectrum licenses in Canada. For additional information, see Note 16, “Canadian ATG Spectrum License,” in our 2016~~10-K.~~28

~~Amortization expense for theone-time~~ ~~payment for each of the next five years and thereafter is estimated to be as follows~~~~(in thousands~~):

Amortization expense totaled less than $0.1 million during the three month periods ended September 30, 2017 and 2016 and $0.1 million during the nine month periods ended September 30, 2017 and 2016.

The monthly payments are expensed as incurred and totaled approximately $0.3 million and $0.9 million, respectively, during the three and nine month periods ended September 30, 2017, and $0.3 million and $0.9 million, respectively, for the prior year periods.

The routes included in ourCA-ROW segment are those that begin and/or end outside of North America (as defined above) on which our international service is provided. BA providesin-flight Internet connectivity and other voice and data communications products and services and sells equipment forin-flight telecommunications to the business aviation market. BA services include Gogo Biz, ourin-flight broadband service, Passenger Entertainment, ourin-flight entertainment service, and satellite-based voice and data services through our strategic alliances with satellite companies.

Factors and Trends Affecting Our Results of Operations

We believe that our operating and business performance is driven by various factors that affect the commercial airline and business aviation industries, including trends affecting the travel industry and trends affecting the customer bases that we target, as well as factors that affect wireless Internet service providers and general macroeconomic factors. Key factors that may affect our future performance include:

costs associated with the implementation of, and our ability to implement on a timely basis our technology roadmap, upgrades and installation of ourATG-4, 2Ku, ~~next generation~~the technology to which our ATG network evolves and other new technologies (including technological issues and related remediation efforts and failures or delays on the part of antenna and other equipment developers and providers, some of which are single source, or delays in obtaining STCs), theroll-out of our satellite services, the ~~use of unlicensed spectrum, the~~ potential licensing or use of additional spectrum, and the implementation of improvements to our network and operations as technology changes and we experience increased network capacity constraints;

costs associated with, and our ability to execute, our international expansion, including modifications of our network to accommodate satellite technology, development and implementation of new satellite-based technologies, the availability of satellite capacity, costs of satellite capacity to which we may have to commit well in advance, and our ability to obtain and comply with foreign telecommunications, aviation and other licenses and approvals necessary for our international operations;

costs associated with managing a rapidly growing company;

costs associated with, and our ability to obtain, sufficient capacity for heavily-trafficked areas in the United States and internationally, the costs of which we may have to commit to well in advance;

the pace and extent of adoption of our service for use on domestic and international commercial aircraft by our current ~~North American~~and new airline partners and ~~new international airline partners;~~customers;

~~Recent Developments~~

~~On September 20, 2017, Gogo Intermediate Holdings LLC (“GIH”) (a wholly owned subsidiary of Gogo Inc.) and Gogo Finance Co. Inc. (a wholly owned subsidiary of GIH) (the“Co-Issuer”~~ and, together with GIH, the “Issuers”), certain subsidiaries of GIH, as guarantors (the “Subsidiary Guarantors” and, together with us, the “Guarantors”), and U.S. Bank National Association, as trustee (in such capacity, the “Trustee”) entered into the first supplemental indenture (the “Supplemental Indenture” and, together with the Original Indenture, the “Indenture”) to modify certain covenants, as discussed below. On September 25, 2017, the Issuers issued $100 million aggregate principal amount of additional senior secured notes due 2022 (the “September 2017 Additional Notes”). The September 2017 Additional Notes were issued at a price equal to 113% of their face value resulting in gross proceeds of $113.0 million. Additionally, we received approximately $2.9 million for interest that accrued from July 1, 2017 through September 24, 2017, which will be paid out when we make our next interest payment in January 2018. We refer to the Original Senior Secured Notes, the January 2017 Additional Notes and the September 2017 Additional Notes collectively as the “Senior Secured Notes.”

As noted above, on September 20, 2017, the Issuers, the Guarantors and the Trustee entered into the Supplemental Indenture to (i) increase the amount of additional secured indebtedness under Credit Facilities (as defined in the Indenture) that may be incurred by the Issuer and its Restricted Subsidiaries (as defined in the Indenture) under the Indenture by $100 million (from $75 million to $175 million in aggregate principal amount), (ii) permit the Issuer and its Restricted Subsidiaries to incur additional secured indebtedness in connection with vendor financing arrangements not to exceed $50 million in aggregate principal amount at any time outstanding and (iii) permit the Issuer and its Restricted Subsidiaries to make additional dividends or distributions to Gogo in an aggregate amount of up to $15 million during any twelve-month period to pay interest on any indebtedness or preferred stock with a maturity later than July 1, 2022. The Supplemental Indenture became effective immediately upon execution, following our receipt of consents from holders of a majority of the outstanding principal amount of the Existing Notes (excluding Existing Notes held by the Issuers or any affiliates of the Issuers) to the Supplemental Indenture and amendments to the collateral agency agreement governing the Senior Secured Notes (the “Consent”). In connection with the Consent, GIH paid $1.4 million in fees (“Consent Fees”) to holders of Existing Notes who validly offered (and did not revoke) their consents prior to the expiration of the Consent.33

~~See Note 8, “Long-Term Debt and Other Liabilities” for additional information on the September 2017 Additional Notes.~~

~~Summary Financial Information~~

Consolidated revenue increased 17.4% and 17.1% to $172.9 million and $511.1 million, respectively, for the three and nine month periods ended September 30, 2017, as compared with $147.3 million and $436.6 million, respectively, for the prior year periods. For the three and nine month periods ended September 30, 2017, the~~CA-NA~~ segment had 2,859 and 2,816, respectively, aircraft equivalents providing the Gogo service as compared with 2,663 and 2,599, respectively, for the prior year periods. As of September 30, 2017, the BA segment had 5,474 aircraft online with satellite systems, including our first 2Ku equipped aircraft in BA, and 4,567 ATG systems online as compared with 5,473 and 3,974, respectively, as of September 30, 2016. For the three and nine month periods ended September 30, 2017, the~~CA-ROW~~ ~~segment had 295 and 250, respectively, aircraft equivalents as compared with 209 and 193, respectively, for the prior year periods.~~

Key Business Metrics

Our management regularly reviews financial and operating metrics, including the following key operating metrics for theCA-NA,CA-ROW and BA segments, to evaluate the performance of our business and our success in executing our business plan, make decisions regarding resource allocation and corporate strategies, and evaluate forward-looking projections.

Aircraft online.We define aircraft online as the total number of commercial aircraft on which our equipment is installed and service has been made commercially available as of the last day of each period presented. We assign aircraft toCA-NA orCA-ROW at the time of contract signing as follows: (i) all aircraft operated by North American airlines and under contract for ATG orATG-4 service are assigned toCA-NA, (ii) all aircraft operated by North American airlines and under a contract for satellite service are assigned toCA-NA orCA-ROW based on whether the routes flown by such aircraft under the contract are anticipated to be predominantly within or outside of North America at the time the contract is signed, and (iii) all aircraft operated bynon-North American airlines and under a contract are assigned toCA-ROW. All aircraft online for theCA-ROW segment are equipped with our satellite equipment.

•

Aircraft equivalents. We define aircraft equivalents for a segment as the number of commercial aircraft online (as defined above) multiplied by the percentage of flights flown by such aircraft within the scope of that segment, rounded to the nearest whole aircraft and expressed as an average of the month end figures for each month in the period. This methodology takes into account the fact that during a particular period certain aircraft may fly routes outside the scope of the segment to which they are assigned for purposes of the calculation of aircraft online.

•

~~Average~~Net annualized average monthly service revenue per aircraft equivalent (“ARPA”). We define net annualized ARPA as the aggregate service revenue plus monthly service fees, some of which are reported as a reduction to cost of service revenue for that segment for the period, less revenue share expense and other transactional costs which are included in cost of service revenue for that segment, divided by the number of months in the period, and further divided by the number of aircraft equivalents (as defined above) for that segment during the ~~period. Satellite~~period, which is then annualized and rounded to the nearest thousand. Beginning with the three month period ended March 31, 2018, we changed the calculation of ARPA ~~is calculated based on satellite~~to be net of revenue share expense and ~~satellite aircraft equivalents, within that segment. ATG~~other transactional expenses in order to better reflect the financial statement impact of revenues generated under both the turnkey model and airline-directed model. The amounts reported above for the three and six month periods ended June 30, 2018 and 2017 reflect this change in methodology. ARPA ~~is calculated based on ATG revenue~~for theCA-NA segment for both the three and ~~ATG aircraft equivalents.~~six month periods ended June 30, 2017 was originally reported as $141 thousand. ARPA for theCA-ROW segment for the three and six month periods ended June 30, 2017 was originally reported as $226 thousand and $215 thousand, respectively.

• ~~Gross passenger opportunity~~~~(“GPO”)~~.~~We define GPO as the aggregate number of passengers who board commercial aircraft on which Gogo service has been available at any time during the period presented~~.When actual passenger counts are available directly from our airline partners, we aggregate such counts across flights on Gogo-equipped aircraft. When not available directly from our airline partners, we estimate GPO. Estimated GPO is calculated by first estimating the number of flights occurring on each Gogo-equipped aircraft, then multiplying by the number of seats on that aircraft, and finally multiplying by a seat factor that is determined from historical information provided to us in arrears by our airline partners. The estimated number of flights is derived from real-time flight information provided to our~~front-end~~ systems by Air Radio Inc. (ARINC), direct airline feeds and supplementary third-party data sources. These aircraft-level estimates are then aggregated with any available airline-provided passenger counts to obtain total GPO.

~~Total average revenue per session~~~~(“ARPS”). We define ARPS as revenue from Passenger Connectivity, excludingnon-session~~ related revenue, divided by the total number of sessions during the period. A session, or a “use” of Passenger Connectivity, is defined as the use by a unique passenger of Passenger Connectivity on a flight segment. Multiple logins or purchases under the same user name during one flight segment count as only one session.

•

~~Connectivity take rate~~. We define connectivity take rate as the number of sessions during the period expressed as a percentage of GPO. Included in our connectivity take-rate calculation are sessions for which we did not receive revenue, including those provided pursuant to free promotional campaigns and, to a lesser extent, as a result of complimentary passes distributed by our customer service representatives for unforeseen technical issues. For the periods listed above, the number of sessions for which we did not receive revenue was not material.

Key Components of Consolidated Statements of Operations

There have been no material changes to our key components of unaudited condensed consolidated statements of operations and segment profit (loss) as described in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” (“MD&A”) in our ~~2016~~201710-K.

Off-Balance Sheet Arrangements

We do not have any obligations that meet the definition of anoff-balance sheet arrangement, other than operating leases, which have or are reasonably likely to have a material effect on our results of operations. See Note ~~10,~~11, “Leases” to our unaudited condensed consolidated financial statements for further information.

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations are based on our unaudited condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The preparation of our unaudited condensed consolidated financial statements and related disclosures require us to make estimates, assumptions and judgments that affect the reported amount of assets, liabilities, revenue, costs and expenses, and related exposures. We base our estimates and assumptions on historical experience and other factors that we believe to be reasonable under the circumstances. In some instances, we could reasonably use different accounting estimates, and in some instances results could differ significantly from our estimates. We evaluate our estimates and assumptions on an ongoing basis. To the extent that there are differences between our estimates and actual results, our future financial statement presentation, financial condition, results of operations and cash flows will be affected.

Revenue Recognition:

We account for revenue in accordance with ASC 606 and ourCA-NA andCA-ROW airline-directed contracts contain multiple performance obligations, which primarily include the sale of equipment, installation services, connectivity services and entertainment services. For these contracts, we account for each distinct good or service as a separate performance obligation. We allocate the contract’s transaction price to each performance obligation using the relative standalone selling price, which is based on the actual selling price for any good or service sold separately to a similar class of customer, if available. To the extent a good or service is not sold separately, we use our best estimate of the standalone selling price and maximize the use of observable inputs. The primary method we use to estimate the standalone selling price is the expected cost-plus margin approach.

We constrain our estimates to reduce the probability of a significant revenue reversal in future periods, allocate such variable consideration to the identified performance obligations and recognize revenue in the period the services are provided. Our estimates are based on historical experience, anticipated future performance, market conditions and our best judgment at the time.

A significant change in one or more of these estimates could affect our estimated contract value. For example, estimates of variable revenue within certain contracts require estimation of the number of sessions or megabytes that will be purchased over the contract term. Estimated revenue under these contracts anticipates increases in take rates over time consistent with our historical experience. Our estimated contract revenue may differ significantly from our initial estimates to the extent actual take rates differ from our historical experience.

As such, we regularly review and update our estimates and recognize adjustments under the cumulativecatch-up method. Any adjustments under this method are recorded as a cumulative adjustment in the period identified and revenue for future periods is recognized using the new adjusted estimate.

See Note 3, “Revenue Recognition,” for additional information.

We believe that the assumptions and estimates associated with revenue recognition, long-lived assets, indefinite-lived assets and stock-based compensation have the greatest potential impact on our unaudited condensed consolidated financial statements. Therefore, we consider these to be our critical accounting policies and estimates.

~~There~~

Other than the addition of revenue recognition noted above, there have been no material changes to our critical accounting policies and estimates as compared to the critical accounting policies and estimates described in MD&A in our ~~2016~~201710-K.

CA-NA service revenue decreased to $95.7 million and $184.5 million, respectively, for the three and six month periods ended June 30, 2018 as compared with $98.7 million and $195.8 million, respectively, for the prior year periods due to a decrease in passenger connectivity revenue offset in part by an increase in ~~aircraft equivalents.~~passenger entertainment and CAS revenue.

CA-NA Passenger Connectivity revenue decreased to $88.8 million and $170.9 million, respectively, for the three and six month periods ended June 30, 2018 as compared with $92.6 million and $184.0 million, respectively, for the prior year periods due to a decrease in passenger-paid revenue offset in part by an increase in airline-paid revenue, which was due primarily to the transition of one of our airline partners to the airline-directed model from the turnkey model and, to a lesser extent, an increase in third party-paid revenue. Under the turnkey model, we are required to pay each airline a percentage of the service revenue we generate from transactions with the airline’s passengers. The revenue share expense is included within cost of service revenue. However, under the airline-directed model, we generate revenue directly from the airline and do not incur revenue share expense. Therefore, the decrease in service revenue under the airline-directed model is offset by a reduction to our revenue share expense within cost of service revenue. We refer to this internally as “differences in business terms.” Service revenue also decreased due to the economic impact of the same airline partner’s transition to the airline-directed model.

Net annualized ARPA decreased to $113 thousand and $108 thousand, respectively, for the three and six month periods ended June 30, 2018, as compared with $114 thousand for both prior year periods. The connectivity take rate increased to ~~7.5%~~

~~Includesnon-session~~ related revenue of $1.0 million and $5.6 million, respectively, for the three and nine month periods ended September 30, 2017, and $4.0 million and $11.9 million, respectively, for the prior year periods.

~~CA-NA~~ Passenger Connectivity revenue increased to $88.3 million and $272.4 million, respectively, for the three and nine month periods ended September 30, 2017, as compared with $84.3 million and $250.1 million, respectively, for the prior year periods. The increase during the three month period ended September 30, 2017 as compared with the prior year period was due to increases in third party-paid and airline-paid revenue, while the increase during the nine month period ended September 30, 2017 as compared with the prior year period was due to increases in passenger-paid, third party-paid and airline-paid revenue. Third party-paid revenue increased primarily due to increases in sponsorship, roaming, enterprise and wholesale revenue. Our airline-paid revenue increased due to new agreements with certain airline partners under which the airlines pay us for specified data usage, including data used by passengers and by airline crew members using connectivity services while in flight. Passenger-paid revenue increased during the nine month period ended September 30, 2017 as compared with the prior year period due to increases in both individual sessions and subscriptions, despite being negatively impacted by the hurricanes during the period.discussed above.

We expect that our cost of equipment revenue ~~in future periods~~ will vary with changes in installations and equipment ~~revenue.~~revenue and, forCA-NA andCA-ROW, costs associated with remediation of quality issues associated with our 2Ku technology.

Engineering, Design and Development Expenses:

Engineering, design and development expenses ~~increased 21.2%~~decreased 20.4% and ~~43.0%~~19.1% to ~~$31.3~~$28.4 million and ~~$103.3~~$58.2 million, respectively, for the three and ~~nine~~six month periods ended ~~September~~June 30, ~~2017,~~2018, as compared with ~~$25.8~~$35.7 million and ~~$72.2~~$71.9 million, respectively, for the prior year ~~periods,~~periods. The decrease for the three month period ended June 30, 2018 as compared with the prior year period was due ~~primarily~~ to ~~increases~~decreased expenses in all three segments, due primarily to ~~higher personnel expense and~~a decrease in outside services, ~~in connection~~while the decrease for the six month period ended June 30, 2018 as compared with the prior year period was due to a decrease inCA-NA expenses whileCA-ROW and BA expenses remained relatively flat.

Engineering, design and development ~~of new products and technologies and obtaining STCs. Additionally, the increase in~~expenses for theCA-NA segment ~~for the three and nine month periods was~~decreased due to the recognition of approximately $3$11.8 million ~~and $16 million, respectively,~~ of expenses during the six month period ended June 30, 2017, related to the development of our next generation ATG solution, primarily due to the achievement of a major ~~development milestones at different points~~milestone, while no such milestone occurred during the ~~year.~~six month period ended June 30, 2018.

We expect consolidated engineering, design and development expenses to decrease as a percentage of consolidated revenue over time.

Sales and Marketing Expenses:

Sales and marketing expenses ~~increased 9.5% and 1.9%~~decreased 6.9% to ~~$16.3~~$15.4 million ~~and $47.3 million, respectively,~~ for the three ~~and nine~~ month ~~periods~~period ended ~~September~~June 30, ~~2017,~~2018, as compared with ~~$14.9~~$16.6 million, ~~and $46.4 million, respectively,~~ for the prior year ~~periods,~~period due to ~~increases~~decreases in ~~the BA~~CA-NA andCA-ROW ~~segments,~~ offset in part by ~~a decrease inCA-NA.~~ ~~The increase in BA andCA-ROW~~ ~~was due primarily to~~ an increase in ~~personnel expense~~BA.

We expect our sales and marketing expenses to increase in future periods as we expand our international marketing initiatives, commence service on aircraft operated by new and existing airline partners in both~~CA-NA~~ ~~andCA-ROW,~~ increase advertising and promotional initiatives for new product offerings (particularly in BA) and expand programs to retain and support our existing users. In addition, the commission component of sales and marketing expenses at BA will fluctuate with equipment revenue. We expect consolidated sales and marketing expenses to decrease as a percentage of consolidated revenue over time.

General and Administrative Expenses:

General and administrative expenses ~~increased 11.1% and 7.9%~~decreased 10.3% to ~~$24.1~~$21.1 million ~~and $70.2 million, respectively,~~ for the three ~~and nine~~ month ~~periods~~period ended ~~September~~June 30, ~~2017,~~2018, as compared with ~~$21.7~~$23.5 million ~~and $65.0 million, respectively,~~ for the prior year ~~periods,~~period due to ~~increases~~a decrease in ~~all three segments,~~CA-NA due primarily to ~~increases~~a decrease in personnel ~~expense.~~related expenses.

WeRelated to our new Integrated Business Plan, we expect to record a severance expense of approximately $2 million in the third quarter of 2018. However, we expect general and administrative expenses to decrease as a percentage of consolidated revenue as we realize economies of scale.

Segment Profit (Loss):

CA-NA’s segment profit ~~increased 10.0%~~decreased 56.5% and 68.2% to ~~$16.0~~$7.0 million and $8.7 million, respectively, for the three and six month ~~period~~periods ended ~~September~~June 30, ~~2017,~~2018, as compared with ~~$14.5~~$16.2 million and $27.4 million, respectively, for the prior year ~~period, while segment profit decreased 7.8% to $43.3 million for the nine month period ended September 30, 2017, as compared with $47.0 million for the prior year period. The increase inCA-NA’s~~ ~~segment profit for the three month period ended September 30, 2017 was~~periods due to an increase in service revenue and decreases in cost of equipment revenue and sales and marketing expense, offset in part by increases in cost of service revenue, engineering, design and development and general and administrative expenses and a decrease in equipment revenue, as discussed above. The decrease in~~CA-NA’s~~ ~~segment profit for~~ the nine month period ended September 30, 2017 was due to increases in cost of service revenue, engineering, design and development and general and administrative expenses and a decrease in equipment revenue, offset in part by an increase in service revenue and decreases in cost of equipment revenue and sales and marketing expense,changes as discussed above.

BA’s segment profit increased ~~3.3%~~45.5% and ~~21.3%~~34.5% to ~~$21.3~~$36.7 million and ~~$72.6~~$69.0 million, respectively, for the three and ~~nine~~six month periods ended ~~September~~June 30, ~~2017,~~2018, as compared with ~~$20.7~~$25.2 million and ~~$59.9~~$51.3 million, respectively, for the prior year ~~periods. The increase in BA’s segment profit for the three and nine month~~ periods ~~ended September 30, 2017 was~~primarily due to ~~an increase in service revenue, partially offset by an increase in operating expenses,~~the changes as discussed above.

CA-ROW’s segment loss ~~increased 21.0%~~decreased 22.1% and ~~30.4%~~18.8% to ~~$24.1~~$24.5 million and ~~$82.1~~$47.1 million, respectively, for the three and ~~nine~~six month periods ended ~~September~~June 30, ~~2017,~~2018, as compared with ~~$19.9~~$31.4 million and ~~$62.9~~$58.0 million, respectively, for the prior year ~~periods.

Depreciation and Amortization:

Depreciation and amortization expense increased ~~33.8%~~4.5% and ~~27.3%~~11.2% to ~~$35.8~~$31.9 million and ~~$96.8~~$67.9 million, respectively, for the three and ~~nine~~six month periods ended ~~September~~June 30, ~~2017,~~2018, as compared with ~~$26.8~~$30.6 million and ~~$76.0~~$61.0 million, respectively, for the prior year periods due to the increase in the number of aircraft outfitted with our airborne equipment by ourCA-ROW andCA-NA segments and ~~accelerated depreciation expense for certain upgrade and decommission programs. See Note 1, “Basis~~amortization of ~~Presentation”~~capitalized software. These increases were partially offset by the transition of one of our airline agreements from the turnkey model to ~~our unaudited condensed consolidated financial statements for additional information on~~ the ~~accelerated depreciation expense.~~airline-directed model.

Interest expense increased during the three and ~~nine~~six month periods ended ~~September~~June 30, ~~2017~~2018 as compared with the prior year periods due to higher average debt levels outstanding ~~and higher average interest rates incurred~~ during the current year as compared with the prior ~~year. The increase in interest expense for the three and nine month periods ended September 30, 2017, as compared to the prior~~ year periods, was due to the issuance of the Original Senior Secured Notes in June 2016, the January 2017 Additional Notes in January 2017 and the September 2017 Additional Notes in September 2017. The increase in interest expense associated with the Senior Secured Notes was partially offset by lower interest expense associated with the Amended and Restated Senior Term Facility, which was repaid in full in June 2016. See Note 8, “Long-Term Debt and Other Liabilities,” in our unaudited condensed consolidated financial statements for additional information. See Note 9, “Interest Costs,” in our unaudited condensed consolidated financial statements for additional information related to our interest expense. The nine month period ended September 30, 2016 included a loss on extinguishment of debt related to the repayment of the Amended and Restated Senior Term Facility and adjustment of deferred financing costs, while the current year did not include such activities.period.

We expect our interest expense to increase due to higher average debt outstanding ~~and higher average interest rates~~ because of the ~~issuance~~issuances of the ~~Senior Secured Notes.

Non-GAAP Measures

In our discussion below, we discuss certainnon-GAAP financial measurements, including Adjusted EBITDA and Cash CAPEX as defined below. Management uses Adjusted EBITDA and Cash CAPEX for business planning purposes, including managing our business against internally projected results of operations and measuring our performance and liquidity. These supplemental performance measures also provide another basis for comparing period to period results by excluding potential differences caused bynon-operational and unusual ornon-recurring items. These supplemental performance measurements may vary from and may not be comparable to similarly titled measures by other companies. Adjusted EBITDA and Cash CAPEX are not recognized measurements under accounting principles generally accepted in the United States, or GAAP, and when analyzing our performance with Adjusted EBITDA or liquidity with Cash CAPEX, as applicable, investors should (i) evaluate each adjustment in our reconciliation to net loss attributable to common stock, and the explanatory footnotes regarding those adjustments, (ii) use Adjusted EBITDA in addition to, and not as an alternative to, net loss attributable to common stock as a measure of operating results, and (iii) use Cash CAPEX in addition to, and not as an alternative to, consolidated capital expenditures when evaluating our liquidity.

Definition and Reconciliation ofNon-GAAP Measures

EBITDA represents net income (loss) attributable to common stock before income taxes, interest income, interest expense, depreciation expense and amortization of other intangible assets.

Adjusted EBITDA represents EBITDA adjusted for (i) stock-based compensation expense, (ii) amortization of deferred airborne lease incentives, (iii) ~~loss on extinguishment~~amortization of ~~debt~~STC costs and (iv) ~~adjustment~~the accounting impact of ~~deferred financing costs.~~the transition to the airline-directed model. Our management believes that the use of Adjusted EBITDA eliminates items that, management believes, have less bearing on our operating performance, thereby highlighting trends in our core business which may not otherwise be apparent. It also provides an assessment of controllable expenses, which are indicators management uses to determine whether current spending decisions need to be adjusted in order to meet financial goals and achieve optimal financial performance.

We believe the exclusion of stock-based compensation expense from Adjusted EBITDA is appropriate given the significant variation in expense that can result from using the Black-Scholes model to determine the fair value of such compensation. The fair value of our stock options is determined using the Black-Scholes model and varies based on fluctuations in the assumptions used in this model, including inputs that are not necessarily directly related to the performance of our business, such as the expected volatility, the risk-free interest rate and the expected life of the options. Therefore, we believe the exclusion of this cost provides a clearer view of the operating performance of our business. Further, stock option grants made at a certain price and point in time do not necessarily reflect how our business is performing at any particular time. While we believe that investors should have information about any dilutive effect of outstanding options and the cost of that compensation, we also believe that stockholders should have the ability to consider our performance using anon-GAAP financial measure that excludes these costs and that management uses to evaluate our business.

We believe the exclusion of the amortization of deferred airborne lease incentives and amortization of STC costs from Adjusted EBITDA is useful as it allows an investor to view operating performance across time periods in a manner consistent with how management measures segment profit and loss (see Note ~~14,~~15, “Business Segments and Major Customers,” for a description of segment profit (loss) in our unaudited condensed consolidated financial statements). Management evaluates segment profit and loss in this manner, excluding the amortization of deferred airborne lease incentives and amortization of STC costs, because such presentation reflects operating decisions and activities from the current period, without regard to the prior period decision or the form of connectivity agreements. ~~See “—Key Components of Consolidated Statements of Operations—Cost of Service Revenue—Commercial Aviation North America and Rest of World” in our 201610-K~~ ~~for a discussion of the accounting treatment of deferred airborne lease incentives.~~

We believe it is useful tofor an understanding of our operating performance to exclude the ~~loss on extinguishment~~accounting impact of ~~debt and adjustment~~the transition by one of ~~deferred financing costs~~our airline partners to the airline-directed model from Adjusted EBITDA because of thenon-recurring nature of ~~these charges.~~this activity.

We also present Adjusted EBITDA as a supplemental performance measure because we believe that this measure provides investors, securities analysts and other users of our financial statements with important supplemental information with which to evaluate our performance and to enable them to assess our performance on the same basis as management.

Cash CAPEX represents capital expenditures net of airborne equipment proceeds received from the airlines. We believe Cash CAPEX provides a more representative indication of our liquidity requirements with respect to capital expenditures, as under certain agreements with our airline partners we are reimbursed for all or a substantial portion of the cost of our airborne equipment, thereby reducing our cash capital requirements.

Material limitations ofNon-GAAP measures

Although EBITDA, Adjusted EBITDA and Cash CAPEX are measurements frequently used by investors and securities analysts in their evaluations of companies, EBITDA, Adjusted EBITDA and Cash CAPEX each have limitations as an analytical tool, and you should not consider them in isolation or as a substitute for, or more meaningful than, amounts determined in accordance with GAAP.

Some of these limitations include:

EBITDA and Adjusted EBITDA do not reflect interest income or expense;

EBITDA and Adjusted EBITDA do not reflect cash requirements for our income taxes;

EBITDA and Adjusted EBITDA do not reflect depreciation and amortization, which are significant and unavoidable operating costs given the level of capital expenditures needed to maintain our business;

Adjusted EBITDA does not reflectnon-cash components of employee compensation;

Cash CAPEX does not reflect the full extent of capital investments we have made in our operations; and

since other companies in our or related industries may calculate these measures differently from the way we do, their usefulness as comparative measures may be limited.

We have historically financed our growth and cash needs primarily through the issuance of common stock,non-convertible debt, senior convertible preferred stock, convertible debt, term facilities and cash from operating activities. We continually evaluate our ongoing capital needs in light of increasing demand for our services, capacity requirements, evolving technologies in our industry and related strategic, operational and technological opportunities. We actively consider opportunities to raise additional capital in the public and private markets utilizing one or more of the types of capital raising transactions through which we have historically financed our growth and cash needs, as well as other means of capital raising not previously used by us.

Liquidity:

Although we can provide no assurances, we currently believe that cash, cash equivalents and short-term investments on hand as of ~~September~~June 30, ~~2017~~2018 will be sufficient to meet our working capital and capital expenditure requirements for at least the next twelve months, including costs associated with installing our airborne equipment on certain aircraft operated by our airline partners, continuing our international expansion and ~~developing~~evolving our ~~next generation~~ ATG ~~solution.~~network. Excluding the impact of our initial public offering in June 2013, the Amended and Restated Senior Term Facility, the Convertible Notes and the Senior Secured Notes, we have not generated positive cash flows on a consolidated basis, and our ability to do so will depend in large part on our ability to increase revenue in each of our three business segments. In addition, our ability to generate positive cash flows from operating activities and the timing of certain capital and other necessary expenditures are subject to numerous variables, such as costs related to international expansion and execution of our current technology roadmap, including 2Ku, ~~next generation~~evolution of our ATG network and other potential future technologies. We currently believe that cash on hand, comprised of cash, cash equivalents and short-term investments, and cash flows provided by operating activities and, if necessary, additional equity financings or the incurrence of additional debt, will be sufficient to meet our liquidity needs in the longer-term, including our continued international expansion and execution of our current technology roadmap. The Indenture governing our Senior Secured Notes contains covenants that limit the ability of GIH and its subsidiaries to incur additional indebtedness. Additionally, the Indenture governing the Senior Secured Notes limits the amount of cash GIH and its subsidiaries may distribute to us, including cash distributed to us to pay interest on the Convertible Notes, to pay any interest on indebtedness incurred, or pay dividends on preferred stock issued by us to refinance, replace, renew or refund the Convertible Notes. Further, market conditions and/or our financial performance may limit our access to additional sources of equity or debt financing. As a result, we may be unable to finance growth of our business to the extent that our cash on hand (including short-term investments) and cash generated through operating activities prove insufficient and we are unable to raise additional financing through the issuance of our equity or through permitted incurrences of debt by us or by GIH and its subsidiaries.

Cash flows (used in) provided by ~~(used in)~~ Operating Activities:

The following table presents a summary of our cash flows from operating activities for the periods set forth below(in thousands):

Net cash provided by (used in) operating activities	$	(4,209	)	$	45,148
Net cash (used in) provided by operating activities							$	(29,029	)	$	2,388

For the ~~nine~~six month period ended ~~September~~June 30, ~~2017,~~2018, cash used in operating activities was ~~$4.2~~$29.0 million as compared with ~~$45.1~~$2.4 million of cash provided by operating activities in the prior year period. The principal contributors to the change in operating cash flows were:

A ~~$18.4 million changes in net loss adjusted fornon-cash~~ ~~charges and credits, and~~

~~A $31.0~~$35.5 million change in cash flows related to operating assets and liabilities resulting from:

A decrease in cash flows due to the following:

~~Changes inCA-NA’s,~~ ~~BA’s andCA-ROW’s~~ ~~accounts receivable due to the timing of collections;~~

◾

Changes inCA-NA’s andCA-ROW’s inventories as we now allocate a portion of our uninstalled airborne equipment to inventory. See Note 5, “Inventories,” for additional information;

◾

Changes inCA-NA’s andCA-ROW’s contract assets due to activity under our airline-directed model during 2018 (see Note 3, “Revenue Recognition” for additional information);

◾

Changes inCA-NA’s andCA-ROW’s deferred airborne lease incentives due to more installations under the turnkey model in 2017 as compared with 2018, as airlines are transitioning to the airline-directed model and as new airlines are being signed under the airline-directed model;

◾

Changes inCA-ROW’s accounts receivable due to the timing of collections; and

◾

Changes inCA-NA’s prepaid expenses as we recognized development services in 2017, while we had no similar activities in 2018;

~~Changes inCA-NA’s~~ ~~and BA’s deferred revenue as deferred revenue balances increased more during 2016 than in 2017;~~

~~Changes inCA-ROW’s~~ ~~deferred airborne lease incentives due to more installations at higher amounts during 2016 as compared with 2017;~~

~~Changes inCA-NA’s~~ ~~accrued liabilities due primarily to the timing of payments; and~~

~~Changes in accrued interest due to the payment of interest on the Senior Secured Notes during 2017 while no such payment was made during 2016, as the Senior Secured Notes were issued in June 2016.~~

Offset in part by an increase in cash flows due to the following:

◾

Changes inCA-NA andCA-ROW’s accrued liabilities due primarily to the timing of payments;

◾

Changes in BA’s inventory due to inventory builds during 2017 while inventory decreased slightly during 2018;

◾

Changes inCA-NA’s and BA’s accounts receivable due to the timing of collections;

◾

Changes inCA-NA’s andCA-ROW’s warranty reserves, due to more activity under our airline-directed model during 2018 (see Note 8, “Warranties” for additional information); and

◾

Changes inCA-NA’s accounts payable due to the timing of payments.

~~Changes~~

Offset in ~~all three segments’ prepaid expenses and other current assets. The change inCA-NA~~ ~~was due to the recognition of development services during 2017 that were paid in 2016. The~~part by a $4.1 million change in ~~BA was due to deposits made on certain inventory items during the first quarter of 2016, while no such payments were made during 2017. The change in~~net loss adjusted for~~CA-ROW~~non-cash ~~was due to the timing of payments on satellite services;~~

~~Changes in BA’s inventory due to inventory builds throughout 2016 while inventory decreased slightly during 2017;~~

~~Changes inCA-NA’s~~ ~~deferred airborne lease incentives due to more installations at higher amounts during 2017 as compared with 2016; and~~

~~Changes inCA-ROW’s~~charges and ~~BA’s accrued liabilities due primarily to the timing of payments.~~credits.

We anticipate cash flows from changes in operating assets and liabilities to be impacted by deferred airborne lease incentives, which we estimate will range from $60 million to $70 million for the year ending December 31, 2017 and $40 million to $50 million for the year ended December 31, 2018. See “—Capital Expenditures” below for further information.

Cash flows used in Investing Activities:

Cash used in investing activities is primarily for capital expenditures related to airborne equipment, cell site construction, software development, and data center upgrades. See “—Capital Expenditures” below. Additionally, cash used in investing activities includes net changes in our short-term investments of a cash inflow of ~~$150.0~~$89.6 million and ~~a cash outflow $119.2~~$55.2 million, respectively, for the ~~nine~~six month ~~period~~periods ended ~~September~~June 30, ~~2017~~2018 and ~~2016.~~2017.

Cash flows (used in) provided by Financing Activities:

Cash used in financing activities for the six month period ended June 30, 2018 was $1.4 million primarily due to capital lease payments.

Cash provided by financing activities for the ~~nine~~six month period ended ~~September~~June 30, 2017 was ~~$175.5~~$66.4 million primarily due to the issuance of the ~~January 2017~~ Additional ~~Notes and the September 2017 Additional~~Senior Secured Notes with gross proceeds of ~~$181.8~~$70.2 million, offset in part by the payment of debt issuance costs for the ~~January 2017~~ Additional ~~Notes and September 2017 Additional~~Senior Secured Notes of ~~$3.6~~$1.5 million and capital lease payments of ~~$2.3 million.~~

Cash used in financing activities for the nine month period ended September 30, 2016 was $202.4 million primarily due to the issuance of $525.0 million of Senior Secured Notes, partially offset by the payment in full of the Amended and Restated Credit Agreement totaling $310.1 million (including the early prepayment penalty of approximately $8.6 million), the payment of debt issuance costs for the Senior Secured Notes of $10.6 million and capital lease payments of $1.9$1.5 million.

Capital Expenditures

Our operations continue to require significant capital expenditures, primarily for technology development, equipment and capacity expansion. Capital expenditures for theCA-NA andCA-ROW segments include the purchase of airborne equipment, which correlates directly to the roll out and/or upgrade of service to our airline partners’ fleets. Capital spending is also associated with the expansion of our ATG network and data centers and includes site acquisition, design, permitting, network equipment and construction costs. We capitalize software development costs related to network technology solutions, the Gogo platform and new product/service offerings. We also capitalized costs related to the build out of our ~~new~~ office locations.

Capital expenditures for the ~~nine~~six month periods ended ~~September~~June 30, 2018 and 2017 ~~and 2016~~ were ~~$214.2~~$115.2 million and ~~$128.7~~$145.7 million, respectively. The ~~increase~~decrease in capital expenditures was primarily due to ~~an increase~~a decrease in airborne equipment purchases ~~(as airborne equipment represents approximately 70%~~as we now allocated a portion of our ~~capital expense~~equipment purchases to inventory (see Note 5, “Inventories” for ~~the current year), primarily for the rollout of 2Ku,~~additional information) and to a lesser extent ~~an increase~~a decrease in capitalized software.

We anticipate that capital expenditures for the year ending December 31, 2017 will range from $290 million to $330 million as we increase purchases of airborne equipment (including 2Ku) that when sold to the airlines will qualify as an operating lease of space, and begin the buildout of our next generation ATG network. We expect our capital expenditures, net of deferred airborne lease incentives, ~~which we estimate will range from $60 million~~ to $70 million, to range from $230 million to $260 million for the year ending December 31, 2017. We anticipate that capital expenditures for the year ending December 31, 2018 will range from $110 million to $170 million. We expect our capital expenditures, net of deferred airborne lease incentives, which we estimate will range from $40 million to $50 million, to range from $70 million to $120 million for the year ending December 31, 2018. The decrease ~~in capital expenditures and related deferred airborne lease incentives~~ in 2018 as compared with ~~2016 and~~ 2017 primarily ~~reflects~~due to decreased turnkey model related activities, under which airborne equipment purchases are treated as capital expenditures. The airborne equipment purchases for our ~~purchases~~airline-directed model activities are treated as inventory activities within operating cash flows. We expect total expenditures of airborne equipment (including both operating and investing activities) to be relatively flat in 2018 ~~that, when sold to airlines, will qualify~~ as ~~sales rather than as operating leases of space on aircraft.~~compared with 2017.

Contractual Commitments:

We have agreements with vendors to provide us with transponder and teleport satellite services. These agreements vary in length and amount and as of ~~September~~June 30, ~~2017~~2018 commit us to purchase transponder and teleport satellite services totaling approximately ~~$21.4~~$43.8 million in ~~2017 (October~~2018 (July 1 through December 31), ~~$75.6 million in 2018, $81.9~~$92.7 million in 2019, ~~$86.2~~$90.4 million in 2020, ~~$75.9~~$77.9 million in 2021, $74.4 million in 2022 and ~~$303.0~~$228.1 million thereafter.

Leases and Cell Site Contracts:We have lease agreements relating to certain facilities and equipment, which are considered operating leases. Additionally, we have operating leases with wireless service providers for tower space and base station capacity on a volume usage basis (“cell site leases”), some of which provide for minimum annual payments. See Note ~~10,~~11, “Leases,” to our unaudited condensed consolidated financial statements for additional information.

For the airline agreements where the equipment transactions are accounted for as operating leases of space, the revenue share paid to our airline partners represents operating lease payments. They are deemed to be contingent rental payments, as the payments due to each airline are based on a percentage of ourCA-NA andCA-ROW service revenue generated from that airline’s passengers, which is unknown until realized. As such, we cannot estimate the lease payments due to an airline at the commencement of our contract with such airline. This rental expense is included in cost of service revenue and is offset by the amortization of the deferred airborne lease incentive discussed above. See Note ~~10,~~11, “Leases,” to our unaudited condensed consolidated financial statements for additional information.

A contract with one of our airline partners requires us to provide the airline partner with a cash rebate of $1.8 million in June 2018. We intend to make the 2018 payment shortly.

Indemnifications and Guarantees: In accordance with Delaware law, we indemnify our officers and directors for certain events or occurrences while the officer or director is, or was, serving at our request in such capacity. The maximum potential amount of future payments we could be required to make under this indemnification is uncertain and may be unlimited, depending upon circumstances. However, our Directors’ and Officers’ insurance does provide coverage for certain of these losses.

~~Quantitative and Qualitative Disclosures About Market Risk~~

ITEM 3. Quantitative and Qualitative Disclosures About Market Risk

Our exposure to market risk is currently confined to our cash and cash equivalents, short-term investments and our debt. We have not used derivative financial instruments for speculation or trading purposes. The primary objectives of our investment activities are to preserve our capital for the purpose of funding operations while at the same time maximizing the income we receive from our investments without significantly increasing risk. To achieve these objectives, our investment policy allows us to maintain a portfolio of cash equivalents and short-term investments through a variety of securities, including U.S. Treasuries, U.S. Government Agency Securities, and Money Market Funds. Our cash and cash equivalents as of ~~September~~June 30, ~~2017~~2018 and December 31, ~~2016~~2017 primarily included amounts in bank checking accounts and Money Market Funds. We believe that a change in average interest rates would not materially affect our interest income and results of operations.

The risk inherent in our market risk sensitive instruments and positions is the potential loss arising from interest rates as discussed below. The sensitivity analyses presented do not consider the effects that such adverse changes may have on the overall economic activity, nor do they consider additional actions we may take to mitigate our exposure to such changes. Actual results may differ.

Interest:Our earnings are affected by changes in interest rates due to the impact those changes have on interest income generated from our cash, cash equivalents and short-term investments. Our cash and cash equivalents as of ~~September~~June 30, ~~2017~~2018 and December 31, ~~2016~~2017 included amounts in bank checking accounts and money market funds, and our short-term investments consist of U.S. Treasury bills. We believe we have minimal interest rate risk; a 10% change in the average interest rate on our portfolio would have reduced interest income for the three ~~and nine~~ month periods ended ~~September~~June 30, ~~2017~~2018 and ~~2016~~2017 by an immaterial amount.

Inflation:We do not believe that inflation has had a material effect on our results of operations. However, there can be no assurance that our business will not be affected by inflation in the future.

Seasonality:Our results of operations for any interim period are not necessarily indicative of those for any other interim period for the entire year because the demand for air travel, including business travel, is subject to significant seasonal fluctuations. We generally expect overall passenger opportunity to be greater in the second and third quarters compared to the rest of the year due to an increase in leisure travel offset in part by a decrease in business travel during the summer months and holidays. We expect seasonality of the air transportation business to continue, which may affect our results of operations in any one period.

~~Controls and Procedures~~

ITEM 4. Controls and Procedures

(a) Evaluation of Disclosure Controls and Procedures

Management, with the participation of our Chief Executive Officer and the Chief Financial Officer, evaluated the effectiveness of the design and operation of the Company’s disclosure controls and procedures (as defined inRules 13a-15(e) and15d-15(e) of the Securities Exchange Act of 1934, as amended) as of ~~September~~June 30, ~~2017.~~2018. Based upon this evaluation, our Chief Executive Officer and the Chief Financial Officer have concluded that our disclosure controls and procedures were effective as of ~~September~~June 30, ~~2017.~~2018.

(b) Changes in Internal Control over Financial Reporting

There have been no changes to our internal control over financial reporting in connection with the evaluation required by Rules13a-15(f) and15d-15(f) under the Exchange Act during the most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

~~Legal Proceedings~~

ITEM 1. LegalProceedings

Linksmart Litigation - On April 20, 2018, Linksmart Wireless Technology, LLC filed suit against us and eight of our airline partners in the U.S. District Court for the Central District of California alleging that our redirection server and login portal infringe a patent owned by the plaintiff. We are required under our contracts with these airlines to indemnify them for defense costs and any liabilities resulting from the suit. Given the very early stage of this litigation, we are unable to assess the merits of the claim, and the outcome of this matter is inherently uncertain.

Pierrelouis Litigation - On June 27, 2018, a purported stockholder of the Company filed a putative class action lawsuit in the United States District Court for the Northern District of Illinois, Eastern Division styled Pierrelouis v. Gogo Inc., naming the Company, its former Chief Executive Officer and Chief Financial Officer and its current Chief Executive Officer, Chief Financial Officer, and President, Commercial Aviation as defendants purportedly on behalf of all purchasers of our securities from February 27, 2017 through May 7, 2018. The complaint asserts claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended, and Rule10b-5 promulgated thereunder, alleging misrepresentations or omissions by us purporting to relate to our 2Ku antenna’s reliability and installation and remediation costs. The plaintiffs seek to recover from us and the individual defendants an unspecified amount of damages. We believe that the claims are without merit and intend to defend them vigorously. In accordance with Delaware law, we will indemnify the individual named defendants for their defense costs and any damages they incur in connection with the suit. We have filed a claim with the issuer of our Directors’ and Officers’ insurance policy with respect to this suit. No amounts have been accrued for any potential losses under this matter, as we cannot reasonably predict the outcome of the litigation or any potential losses.

From time to time we may become involved in other legal proceedings arising in the ordinary course of our business. We cannot predict with certainty the potential for or outcome of any future litigation. Regardless of the outcome of any particular litigation and the merits of any particular claim, litigation can have a material adverse impact on our company due to, among other reasons, any injunctive relief granted, which could inhibit our ability to operate our business, amounts paid as damages or in settlement of any such matter, diversion of management resources and defense costs.

~~Risk Factors~~

ITEM 1A. Risk Factors

Except as set forth below and in our Quarterly Report on Form10-Q for the quarter ended March 31, ~~2017~~2018, as filed with the SEC on May 4, ~~2017,~~2018, there have been no material changes to the risk factors previously disclosed in our ~~2016~~201710-K.

There can be no assurance that our implementation of a new business plan will be successful.

~~ITEM 2.~~

~~Unregistered Sales of Equity Securities and Use of Proceeds~~

On July 12, 2018, we announced a new Integrated Business Plan (the “IBP”), which is intended to significantly reduce our cost structure, improve quality, drive revenue, streamline business processes, improve the terms of our airline contracts by reducing equipment subsidies and strengthen our balance sheet. In connection with the development of the IBP, our Board asked management to assess whether shareholder value would be increased by engaging in any of the strategic and/or financial relationships and transactions that have been suggested to us by third parties. There can be no assurance that changes under the IBP will result in improvements to our operational or financial performance, that negotiations with airline partners will be successful or that we will pursue any strategic or financial relationship or transaction, and the outcome of any change is uncertain. Further, the process of implementing initiatives under the IBP will involve the dedication of significant resources and the incurrence of significant costs and expenses. If we are unable to mitigate these or other potential risks caused by our implementation of the IBP, it may disrupt our business or adversely impact our revenue, operating results and financial condition.

If we are unable to timely remediate 2Ku quality and performance issues related to deicing fluid or other moisture entering our antennas, our business, financial condition and results of operations may be materially adversely affected.

As we have deployed 2Ku, we have encountered delays and quality problems arising from the entry into our antennas of moisture or liquids that may be caused by deicing procedures or other operational tasks (such as cleaning) that our airline partners may undertake or by humidity or condensation. In particular, the ingress of deicing fluid resulted in significant antenna performance issues in the winter of 2017-2018. We have incurred and will continue to incur significant costs in remediating these problems. Our success in remediating these problems and the time and costs required to effect such remediation will depend on multiple factors, some of which are beyond our control, including: (i) the timing of completion, results of testing and adequacy of our remediation solutions, (ii) the availability of aircraft for installation of such solutions, (iii) our ability to make such solutions available for installation on a timely

~~Sales of Unregistered Securities~~

basis, and (iv) the ability of airlines and third parties to perform installations consistent with our specifications and on a timely basis. In the event that the deicing issue is not remediated by the winter of 2018-2019 in a manner that enables 2Ku performance to meet the standards set forth in our airline contracts or if we fail to remediate other moisture issues when and as required to meet such standards, we will be in breach of airline contracts, which could result in penalties, damages or termination rights on the part of airlines, in airlines deciding not to market our services, and in harm to our reputation with passengers and other airlines, all of which would have a material adverse effect on our business, financial condition and results of operations.
