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 as filed with the Securities and Exchange Commission (“SEC”) on February 27, 2017 (the “201610-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 ~~six~~nine month period ended ~~June~~September 30, 2017 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2017.

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

Use of Estimates - —The preparation of financial statements in conformity with 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 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.

Under agreements with certain of our airline partners to upgrade our equipment on certain aircraft or decommission certain aircraft on which our equipment is installed, on a quarterly basis we reassess the useful life of the affected equipment. As a result, we shorten the useful lives of the affected equipment to be consistent with the estimated upgrade date or aircraft decommissioning date, as applicable. We also shorten the remaining amortization period for deferred airborne lease incentives for certain equipment on aircraft to be decommissioned. The change in estimated useful lives related 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.

In May 2014, 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 principle 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 the annual reporting ~~periods. We~~periods; we will adopt this guidance as of January 1, ~~2018~~2018. We are continuing to evaluate our revenue contracts under 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 ~~we expect~~now plan to ~~apply this~~adopt the standard using the ~~full~~modified retrospective method. ~~During 2016, we established~~Under the modified retrospective method, revenue and expenses that would have been recognized in the future will be recorded to equity as a ~~project team responsible for assessment and implementation~~cumulative adjustment at the date of ~~this guidance.~~adoption. While we are continuing to evaluate the impact of the adoption of this guidance on our consolidated financial statements, we currently believe

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

that the measurement and timing of recognition of revenue and related costs from certain of our~~CA-NA,CA-ROW~~ ~~and BA customers~~ customer contracts will be impacted in the following ways, ~~(however~~primarily from our Airline Directed contracts inCA-NA andCA-ROW (cash flows and cash and cash equivalents will not be impacted):

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.

In March 2016, the FASB issued ASU2016-02,Leases (“ASU2016-02”), which introduces a lessee model that records most leases on the balance sheet. ASU2016-02 also aligns certain underlying principles of the new lessor model with those in Accounting Standards Codification (“ASC”) 606,Revenue from Contracts with Customers(“ASC 606”), the FASB’s new revenue recognition standard. Furthermore, ASU2016-02 eliminates the required use of bright-line tests used in current GAAP for determining lease classification. It also requires lessors to provide

additional transparency into their exposure to the changes in value of their residual assets and how they manage that exposure. ASU2016-02 is effective for annual reporting periods beginning after December 15, 2018, including interim periods within those annual reporting periods. We will adopt this as guidance as of January 1, 2019 and we are currently evaluating the impact of the adoption of this guidance on our consolidated financial statements.

In March 2016, the FASB issued ASU2016-04,Recognition of Breakage for Certain Prepaid Stored-Value Products (“ASU2016-04”), which amends the guidance on extinguishing financial liabilities for certain prepaid stored-value products by requiring that entities that sell prepaid stored-value products recognize breakage proportionally as the prepaid stored-value product is being redeemed rather than immediately upon sale of the product. If an entity is unable to estimate breakage, the amount would be recognized when the likelihood becomes remote that the holder will exercise the remaining rights. Entities are required to reassess their estimates of breakage each reporting period. Any change in this estimate would be accounted for as a change in an accounting estimate. An entity that recognizes breakage is required to disclose the methodology used to recognize breakage and significant judgments made in applying the breakage methodology. ASU2016-04 is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, and early adoption is permitted. We can apply ASU2016-04 by using either a modified retrospective transition approach or a full retrospective transition approach. We will adopt this as guidance as of January 1, 2018 and we are currently evaluating the impact of the adoption of this guidance on our consolidated financial statements.

In August 2016, the FASB issued ASU2016-15,Classification of Certain Cash Receipts and Cash Payments (“ASU2016-15”), which amends ASC 230,Statement of Cash Flows, the FASB’s standards for reporting cash flows in general-purpose financial statements. The amendments address the diversity in practice related to the classification of certain cash receipts and payments including debt prepayment or debt extinguishment costs. ASU2016-15 is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, and early adoption is permitted. We will adopt this guidance as of January 1, 2018 and we expect to apply this standard using the full retrospective method. We do not believe adoption of this guidance will have a material effect on our cash flows as we have historically reported debt prepayment and debt extinguishment costs in a manner consistent with ASU2016-15.

In October 2016, the FASB issued ASU2016-16,Intra-Entity Transfers of Assets Other Than Inventory (“ASU2016-16”), which removes the prohibition in ASC 740,Income Taxes, against the immediate recognition of the current and deferred income tax effects of intra-entity transfers of assets other than inventory. This is intended to reduce the complexity of GAAP and diversity in practice related to the tax consequences of certain types of intra-entity asset transfers, particularly those involving intellectual property. ASU2016-16 is effective for annual reporting periods beginning after December 15, 2017, including interim periods within those annual reporting periods. We will adopt this guidance as of January 1, 2018 and we are currently evaluating the impact of the adoption of this guidance on our consolidated financial statements.

In November 2016, the FASB issued ASU2016-18,Restricted Cash – A Consensus of the FASB Emerging Issues Task Force, (“ASU2016-18”), which amends ASC 230,Statement of Cash Flows, to clarify guidance on the classification and presentation of restricted cash in the statement of cash flows. ASU2016-18 is effective for annual reporting periods beginning after December 15, 2017, including interim periods within those annual reporting periods. We will adopt this guidance as of January 1, 2018 and do not believe the adoption of this guidance will have a material impact on our consolidated financial statements.

In January 2017, the FASB issued ASU2017-04,Simplifying the Test for Goodwill Impairment (“ASU2017-04”), which simplifies the accounting for goodwill impairments by eliminatingStep-2 from the goodwill impairment test. ASU2017-04 is effective for annual reporting periods beginning after December 15, 2019 and early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. We will adopt this guidance as part of our annual goodwill impairment test in October 2017 and do not believe the adoption of this guidance will have a material impact on our consolidated financial statements.

In May 2017, the FASB issued ASU2017-09,Scope of Modification Accounting(“ASU2017-09”), which amends the scope of modification accounting for share-based payment arrangements. The ASU provides guidance on the types of changes to the terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting under ASC 718,Compensation – Stock Compensation.Specifically, an entity would not apply modification accounting if the fair value, vesting conditions, and classification of the awards are the same immediately before and after the modification. ASU2017-09 is effective for annual reporting periods beginning after December 15, 2017 and early adoption is permitted. We will adopt this guidance as of January 1, 2018 and do not believe the adoption of this guidance will have a material impact on our consolidated financial statements.

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, “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 ~~June~~September 30, 2017 and 2016 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 ~~six~~nine month periods ended ~~June~~September 30, 2017 and 2016, 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.

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

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

Our intangible assets are comprised of both indefinite-lived and finite-lived intangible assets. 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 indicated no impairment.

As of ~~June~~September 30, 2017 and December 31, 2016, our goodwill balance, all of which related to our BA segment, was $0.6 million.

We provide warranties on parts and labor related to our products. Our warranty terms range from two to five years. Warranty reserves are established for costs that are estimated to be incurred after the sale, delivery and installation of the products under warranty. The warranty reserves are determined based on known product failures, historical experience and other available evidence, and are included in accrued liabilities in our unaudited condensed consolidated balance sheets.

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 ~~“Indenture”~~“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 senior secured notes due 2022 (the ~~“Additional~~“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 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 ~~June~~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.

As of September 30, 2017 and December 31, 2016, the outstanding principal ~~balance~~amount of the Senior Secured Notes was ~~$590.0~~$690.0 million and $525.0 million, respectively. The unamortized debt premium ~~was $4.8~~and Consent fees were $16.3 million as of ~~June~~September 30, 2017 and the net carrying amount was ~~$594.8~~$706.3 million as of ~~June~~September 30, 2017. The net carrying amount was $525.0 million as of December 31, 2016.

Interest on the Senior Secured Notes accrues at the rate of 12.500% per annum and is payable semi-annually in arrears on July 1 and January 1, commencing on January 1, 2017 (other than the January 2017 Additional Notes, for which interest payments commenced on July 1, ~~2017)~~2017, and the September 2017 Additional Notes, for which interest payments will commence 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 ~~Additional Notes and the Original~~ Senior Secured Notes.

We paid approximately $11.4 million, $2.0 million and ~~$2.0~~$2.5 million, respectively, of ~~Senior Secured Notes~~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, which 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 ~~$0.6~~$0.5 million and ~~$1.1~~$1.6 million, respectively, for the three and ~~six~~nine month periods ended ~~June~~September 30, 2017, and ~~$0.1~~$0.4 million and ~~$0.1~~$0.5 million, respectively, for the prior year periods. As of ~~June~~September 30, 2017 and December 31, 2016, the balance of unamortized deferred financing costs related to the Senior Secured Notes was ~~$11.3~~$13.2 million and $11.2 million, respectively, and is included as a reduction to long-term debt in our unaudited condensed consolidated balance sheet. See Note 9, “Interest Costs” for additional information.

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

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:

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.

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

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:

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 ~~June~~September 30, 2017, 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

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

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, “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 ~~June~~September 30, 2017 and December 31, 2016, the outstanding principal on the Convertible Notes was $361.9 million, the unamortized debt discount was ~~$60.4~~$55.4 million and $69.9 million, respectively, and the net carrying amount of the liability component was ~~$301.5~~$306.5 million and $292.0 million, respectively.

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 to 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 ~~$0.3~~$0.4 million and ~~$0.7~~$1.1 million, respectively, for the three and ~~six~~nine months periods ended ~~June~~September 30, 2017, and ~~$0.3~~$0.4 million and ~~$0.7~~$1.0 million, respective, for the prior year periods. Amortization expense is included in interest expense in the unaudited condensed consolidated statements of operations. As of ~~June~~September 30, 2017 and December 31, 2016, the balance of unamortized deferred financing costs related to the Convertible Notes was ~~$4.7~~$4.0 million and $5.1 million, respectively, and is included as a reduction to long-term debt in our unaudited condensed consolidated balance sheets. See Note 9, “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:

None of the above events allowing for conversion prior to December 1, 2019 occurred during the three and ~~six~~nine month periods ended ~~June~~September 30, 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

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

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 201610-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 ~~$0.6 million and~~ $1.4 million ~~respectively,~~ for the ~~three and six~~nine month ~~periods~~period ended ~~June~~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 million and $7.9 million, respectively, as of ~~June~~September 30, 2017 and December 31, 2016 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 ~~six~~nine month periods ended ~~June~~September 30, 2017 and 2016(in thousands):

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

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 service to passengers on the aircraft. There are currently two types of commercial airline arrangements: Turnkey and Airline Directed.

Under the 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 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 ~~Airline Directed~~Turnkey model, ~~which~~ we ~~have historically used on~~refer to our relationship with the airline as 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. For more information see Note 2, “Summary of Significant Accounting Policies” in our~~10-K.~~“partner”.

Under the Turnkey model, the assets are recorded as airborne equipment on our unaudited condensed consolidated balance sheets, as noted in Note 5, “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 ~~$8.6~~$10.1 million and ~~$18.0~~$28.1 million, respectively, for the three and ~~six~~nine month periods ended ~~June~~September 30, 2017, and ~~$7.2~~$7.8 million and ~~$12.9~~$20.7 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 ~~June~~September 30, 2017, deferred airborne lease incentives of ~~$35.3~~$39.1 million and ~~$117.5~~$121.6 million, respectively, are included in current andnon-current liabilities in our unaudited condensed consolidated balance sheet. As of December 31, 2016, deferred airborne lease incentives of $36.3 million and $135.9 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 to the transition in the accounting treatment for one of our airline agreements from a Turnkey model in the prior year period to an Airline Directed model in the first quarter of 2017 due to specific provisions elected by the airline.

Under the 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 ~~$10.2~~$7.7 million and ~~$19.1~~$26.9 million, respectively, for the three and ~~six~~nine month periods ended ~~June~~September 30, 2017, and ~~$10.8~~$10.1 million and ~~$22.2~~$32.3 million, respectively, for the prior year periods.

A contract with one of our airline partners requires us to provide the airline partner with a cash ~~rebates~~rebate of $1.8 million in June ~~2017~~2018.

Under 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 ~~June 2018. We paid~~services are not separable, equipment revenue is deferred and recognized over the ~~2017 rebate on June 13, 2017.~~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 201610-K.

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 ~~$6.0~~$9.0 million, respectively, for the three and ~~six~~nine month periods ended ~~June~~September 30, 2017, and ~~$2.9~~$3.0 million and ~~$6.0~~$8.9 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. Total cell site rental expense was ~~$2.4~~$2.3 and ~~$4.7~~$7.0 million, respectively, for the three and ~~six~~nine month periods ended ~~June~~September 30, 2017, and ~~$2.4~~$2.3 million and ~~$4.7~~$7.0 million, respectively, for the prior year periods.

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 ~~June~~September 30, 2017, are as follows (in thousands):


			Operating
Years ending December 31,	Operating Leases		Leases

Thereafter	$	95,061	$	95,693

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 ~~June~~September 30, 2017 and December 31, 2016 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 million and $3.9 million, respectively. As of ~~June~~September 30, 2017 and December 31, 2016, 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 ~~June~~September 30, 2017, are as follows (in thousands):

The ~~$4.4~~$3.6 million present value of net minimum lease payments as of ~~June~~September 30, 2017 has a current portion of ~~$2.6~~$2.1 million included in the current portion of long-term debt and capital leases and anon-current portion of ~~$1.8~~$1.5 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 ~~June~~September 30, 2017 commit us to purchase transponder and teleport satellite services totaling approximately ~~$41.7~~$21.4 million in 2017 ~~(July~~(October 1 through December 31), ~~$72.9~~$75.6 million in 2018, ~~$79.1~~$81.9 million in 2019, ~~$85.4~~$86.2 million in 2020, $75.9 million in 2021 and $303.0 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.

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.

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

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.

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 ~~June~~September 30, 2017 unaudited condensed consolidated balance sheet, excluding any issuance costs, is the amount that a market participant would be willing to lend at ~~June~~September 30, 2017 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 ~~June~~September 30, 2017 and December 31, 2016 were as follows(in thousands):


	June 30, 2017					December 31, 2016					September 30, 2017					December 31, 2016
	Fair Value ⁽¹⁾		Carrying Value			Fair Value ⁽¹⁾		Carrying Value			Fair Value ⁽¹⁾		Carrying Value			Fair Value ⁽¹⁾		Carrying Value
Senior Secured Notes	$	673,000	$	594,849	⁽²⁾	$	572,000	$	525,000		$	788,000	$	706,277	⁽²⁾	$	572,000	$	525,000
Convertible Notes		330,000		301,517	⁽³⁾		275,000		292,024	⁽³⁾		333,000		306,462	⁽³⁾		275,000		292,024	⁽³⁾

We haveheld-to-maturity financial instruments where carrying value approximates fair value. There were no fair value adjustments to these financial instruments during 2017 and 2016.

The effective income tax rates for the three and ~~six~~nine month periods ended ~~June~~September 30, 2017 was (0.8%) and (0.7%), respectively, and ~~(0.6%~~(1.4%) and ~~(0.8%~~(1.0%), respectively, for the prior year periods. Income tax expense recorded in each

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

period was similar, with differences inpre-tax income causing the change in the effective tax rate. The difference between our effective tax rates and the U.S. federal statutory rate of 35% for the three and ~~six~~nine month periods ended ~~June~~September 30, 2017 and 2016 was 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, France and ~~Australia.~~Germany. With few exceptions, as of ~~June~~September 30, 2017, we are no longer subject to U.S. federal, state, local or foreign examinations by tax authorities for years before 2013.

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 ~~six~~nine month periods ended ~~June~~September 30, 2017 and 2016. As of ~~June~~September 30, 2017 and December 31, 2016, 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”~~CA-ROW,” and Business Aviation, or “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 201610-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 of foreign 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 assets are not material as of ~~June~~September 30, 2017 and December 31, 2016. 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 (including amortization of deferred airborne lease incentives, stock-based compensation expense and adjustment to deferred financing costs) 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.

ITEM 2.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis is intended to help the reader understand our business, financial condition, results of operations, liquidity and capital resources. You should read this discussion in conjunction with our unaudited condensed consolidated interim financial statements and the related notes contained elsewhere in this Quarterly Report on Form10-Q. Unless the context otherwise indicates or requires, the terms “we,” “our,” “us,” “Gogo,” and the “Company,” as used in this report, refer to Gogo Inc. and its directly and indirectly owned subsidiaries as a combined entity, except where otherwise stated or where it is clear that the terms refer only to Gogo Inc. exclusive of its subsidiaries.

The statements in this discussion regarding industry outlook, our expectations regarding our future performance, liquidity and capital resources and othernon-historical statements in this discussion are forward-looking statements. These forward-looking statements are subject to numerous risks and uncertainties, including, but not limited to, the risks and uncertainties described under “Risk Factors” in the 201610-K and Item 1A in this Quarterly Report on Form10-Q, and in “Special Note Regarding Forward-Looking Statements” in this report. Our actual results may differ materially from those contained in or implied by any forward-looking statements.

Our fiscal year ends December 31 and, unless otherwise noted, references to “years” or “fiscal” are for fiscal years ended December 31. See “— Results of Operations.”

Gogo (“we”, “us”, “our”) is the global leader in providing broadband connectivity solutions and wirelessin-flight entertainment to the aviation industry. We operate through the following three segments: Commercial Aviation North America, or“CA-NA,” Commercial Aviation Rest of World, or“CA-ROW,” and Business Aviation, or “BA.”

Services provided by ourCA-NA andCA-ROW businesses include Passenger Connectivity, which allows passengers to connect to the Internet from their personalWi-Fi-enabled devices; Passenger Entertainment, which offers passengers the opportunity to enjoy a broad selection ofin-flight entertainment options on their personalWi-Fi enabled devices; and Connected Aircraft Services (“CAS”), which offers airlines connectivity for various operations and currently include, among others, real-time credit card transaction processing, electronic flight bags and real-time weather information. Services are provided byCA-NA on commercial aircraft flying routes that generally begin and end within North America, which for this purpose includes the United States, Canada and Mexico.CA-ROW provides service on commercial aircraft operated by foreign-based commercial airlines and flights outside of North America for North American based commercial airlines. 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.

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:

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.

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

Consolidated revenue increased 17.4% and 17.1% ~~and 16.9%~~ to ~~$172.8~~$172.9 million and ~~$338.2~~$511.1 million, respectively, for the three and ~~six~~nine month periods ended ~~June~~September 30, 2017, ~~and $147.5~~as compared with $147.3 million and ~~$289.3~~$436.6 million, respectively, for the prior year periods. For the three and ~~six~~nine month periods ended ~~June~~September 30, 2017, theCA-NA segment had ~~2,816~~2,859 and ~~2,794,~~2,816, respectively, aircraft equivalents providing the Gogo service as compared with ~~2,622~~2,663 and ~~2,567,~~2,599, respectively, for the prior year periods. As of ~~June~~September 30, 2017, the BA segment had ~~5,464~~5,474 aircraft online with satellite systems, including our first 2Ku equipped aircraft in BA, and ~~4,453~~4,567 ATG systems online as compared with ~~5,458~~5,473 and ~~3,795,~~3,974, respectively, as of ~~June~~September 30, 2016. For the three and ~~six~~nine month periods ended ~~June~~September 30, 2017, theCA-ROW segment had ~~247~~295 and ~~227,~~250, respectively, aircraft equivalents as compared with ~~196~~209 and ~~186,~~193, respectively, for the prior year periods.

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.

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 201610-K.

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, “Leases” to our unaudited condensed consolidated financial statements for further information.

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.

We believe that the assumptions and estimates associated with 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 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 201610-K.

See Note 2, “Recent Accounting Pronouncements” into our unaudited condensed consolidated financial statements for additional information.

The following table sets forth, for the periods presented, certain data from our unaudited condensed consolidated statements of operations. The information contained in the table below should be read in conjunction with our unaudited condensed consolidated financial statements and related notes.

CA-NA revenue increased to ~~$101.0~~$95.7 million and ~~$199.8~~$295.5 million, respectively, for the three and ~~six~~nine month periods ended ~~June~~September 30, 2017, as compared with ~~$92.7~~$90.7 million and ~~$179.7~~$270.5 million, respectively, for the prior year periods, primarily due to an increase in service revenue driven by increased Passenger Connectivity revenue. The increase inCA-NA Passenger Connectivity revenue for the three and ~~six~~nine month periods ended ~~June~~September 30, 2017 was primarily due to an increase in connectivity take rate and an increase in the number of aircraft equivalents, offset in part by a decrease in ARPS. GPO increased to ~~108.5~~110.8 million and ~~204.1~~314.9 million, respectively, for the three and ~~six~~nine month periods ended ~~June~~September 30, 2017, as compared with ~~100.5~~108.4 million and ~~190.5~~298.8 million, respectively, for the prior year periods, driven by an increase in aircraft equivalents. The connectivity take rate increased to ~~7.7% and 8.0%,~~7.5%

and 7.8%, respectively, for the three and ~~six~~nine month periods ended ~~June~~September 30, 2017, as compared with ~~6.3%~~6.5% and 6.4%, respectively, for the prior year periods, reflecting increased passenger adoption including the impact of third party-paid and airline-paid promotions. Passenger Connectivity sessions totaled 8.3 million and ~~16.3~~24.6 million, respectively, for the three and ~~six~~nine month periods ended ~~June~~September 30, 2017, as compared with ~~6.3~~7.0 million and ~~12.2~~19.2 million, respectively, for the prior year periods. ARPS decreased to ~~$10.86~~$10.49 and ~~$11.01,~~$10.83, respectively, for the three and ~~six~~nine month periods ended ~~June~~September 30, 2017, as compared with ~~$12.94~~$11.46 and ~~$12.99,~~$12.43, respectively, for the prior year periods, due to shifts in product mix, third party-paid and airline-paid promotions. Total ARPA was $11.1 thousand for both the three month period ended September 30, 2017 and 2016, and increased to ~~$11,784~~$11.6 thousand for the nine month period ended September 30, 2017, as compared with $11.3 thousand for the prior year period. Total ARPA is comprised of Satellite ARPA of $18.4 thousand and ~~$11,789,~~$19.1 thousand, respectively, and ATG ARPA of $10.4 thousand and $11.0 thousand, respectively, for the three and ~~six~~nine month periods ended ~~June~~September 30, ~~2017, as compared with $11,483 and $11,314, respectively, for the prior year periods.~~2017.

A summary of the components ofCA-NA’s service revenue for the three and ~~six~~nine month periods ended ~~June~~September 30, 2017 and 2016 is as follows(in thousands, except for percent change):

CA-NA Passenger Connectivity revenue increased to ~~$92.6~~$88.3 million and ~~$184.0~~$272.4 million, respectively, for the three and ~~six~~nine month periods ended ~~June~~September 30, 2017, as compared with ~~$85.7~~$84.3 million and ~~$165.7~~$250.1 million, respectively, for the prior year ~~periods,~~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. ~~Passenger-paid revenue increased due to increases in both individual sessions and subscriptions.~~ 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.

The increase in Passenger Entertainment and CAS revenue to $6.1 million and ~~$11.8~~$17.9 million, respectively, for the three and ~~six~~nine month periods ended ~~June~~September 30, 2017, as compared with ~~$4.1~~$4.2 million and ~~$7.5~~$11.7 million, respectively, for the prior year periods, was ~~primarily~~ due to increased usage of CAS operational applications and Passenger Entertainment services underbusiness-to-business arrangements with our airline partners.

The increase inCA-NA service revenue was partially offset by a decrease in equipment revenue to ~~$2.3~~$1.3 million and ~~$3.9~~$5.2 million, respectively, for the three and ~~six~~nine month periods ended ~~June~~September 30, 2017, as compared with ~~$2.9~~$2.2 million and ~~$6.5~~$8.7 million, respectively, in the prior year periods, due primarily to more equipment transactions qualifying for sales treatment (instead of lease treatment) in the prior year period as compared with the current year.

BA revenue increased to ~~$57.8~~$60.5 million and ~~$114.1~~$174.6 million, respectively, for the three and ~~six~~nine month periods ended ~~June~~September 30, 2017, as compared with ~~$49.1~~$48.9 million and ~~$99.2~~$148.1 million, respectively, for the prior year periods, due to an increase in service revenue. BA revenue ~~offset in part~~was also positively impacted by ~~a decrease~~an increase in equipment ~~revenue.~~revenue during the three month period ended September 30, 2017 as compared with the prior year period, while equipment revenue decreased during the nine month period ended September 30, 2017 as compared with the prior year period.

BA service revenue increased to ~~$42.2~~$43.2 million and ~~$82.2~~$125.4 million, respectively, for the three and ~~six~~nine month periods ended ~~June~~September 30, 2017, as compared with ~~$32.4~~$33.3 million and ~~$63.1~~$96.4 million, respectively, for the prior year periods, primarily due to more customers subscribing to our Gogo Biz (ATG) service and an increase in average monthly service revenue per aircraft online. The number of ATG aircraft online increased ~~17.3%~~14.9% to ~~4,453~~4,567 as of ~~June~~September 30, 2017 as compared with ~~3,795~~3,974 as of ~~June~~September 30, 2016.

BA equipment revenue ~~decreased~~increased to ~~$15.6~~$17.3 million ~~and $31.9 million, respectively,~~ for the three ~~and six~~ month ~~periods~~period ended ~~June~~September 30, 2017, as compared with ~~$16.7~~$15.6 million, ~~and $36.1 million, respectively,~~ for the prior year ~~periods,~~period, due to an increase in ATG equipment revenue partially offset by a decrease in satellite equipment revenue. Equipment revenue decreased to $49.2 million for the nine month period ended September 30, 2017, as compared with $51.7 million in the prior year period due to decreases in ~~both ATG and~~ satellite equipment revenue ~~consistent with trends~~offset in ~~the overall business aviation market.~~part by an increase in ATG equipment revenue.

Under a sales program for Gogo Biz 4G equipment that started in 2016, we have deferred approximately ~~$5.5~~$5.2 million of equipment revenue as of ~~June~~September 30, 2017 in connection with a free upgrade program under which we shipped ATG and UCS equipment to customers who have a right to exchange that equipment for Gogo Biz 4G equipment. In the three and ~~six~~nine months ended ~~June~~September 30, 2017, we shipped 3four and seven Gogo Biz 4G units, respectively, under this program and recognized ~~$0.2~~$0.3 million and $0.5 million, respectively, of previously deferred equipment revenue. We will recognize the remaining deferred revenue upon the earlier of the shipment of the Gogo Biz 4G equipment or the expiration of the free upgrade period, which is June 30, 2018.

CA-ROW revenue increased to ~~$14.1~~$16.6 million and ~~$24.4~~$41.0 million, respectively, for the three and ~~six~~nine month periods ended ~~June~~September 30, 2017, as compared with ~~$5.7~~$7.6 million and ~~$10.3~~$17.9 million, respectively, for the prior year periods, due to an increase in service revenue and to a lesser extent an increase in equipment revenue.

CA-ROW service revenue increased to ~~$13.2~~$15.7 million and ~~$22.6~~$38.2 million, respectively, for the three and ~~six~~nine month periods ended ~~June~~September 30, 2017, as compared with ~~$5.4~~$7.2 million and ~~$10.0~~$17.2 million, respectively, for the prior year periods, due to an increase in ARPA and to a lesser extent an increase in aircraft equivalents. ARPA for theCA-ROW segment increased to ~~$18,872~~$18.8 thousand and ~~$17,932~~$18.3 thousand for the three and ~~six~~nine month periods ended ~~June~~September 30, 2017, respectively, as compared with ~~$12,065~~$14.5 thousand and ~~$11,851,~~$12.8 thousand, respectively, for the prior year periods, due to increased airline-paid passenger usage and the transition in the accounting treatment for one of our airline agreements from an operating lease or Turnkey model in the prior year to a sale or Airline Directed model in the first quarter of the current year due to specific provisions elected by the airline. Take rate was 13.5% and 14.3%, respectively, for the three and nine month periods ended September 30, 2017.

CA-ROW generated equipment revenue of ~~$0.9~~$1.0 million and ~~$1.8~~$2.8 million, respectively, for the three and ~~six~~nine month periods ended ~~June~~September 30, 2017, as compared with $0.4 million and ~~$0.4~~$0.7 million, respectively, for the prior year periods, due to the transition in the accounting treatment for one of ~~one~~our airline agreements from an operating lease or Turnkey model in the prior year to a sale or Airline Directed model in the first quarter of the current year due to specific provisions elected by the airline.

CA-ROW cost of service revenue increased to ~~$21.3~~$20.0 million and ~~$39.9~~$59.9 million, respectively, for the three and ~~six~~nine month periods ended ~~June~~September 30, 2017, as compared with ~~$10.7~~$11.3 million and ~~$20.6~~$31.9 million, respectively, for the

prior year periods, primarily due to increases in network operations expenses (including satellite service fees), aircraft operations expenses, revenue share expense and billing and transaction related expenses as the business continued to grow. Cost of service revenue was further impacted by decreases in the amortization of our deferred airborne lease incentives, the recognition of monthly service fees and maintenance fees paid to us by certain of our airline partners, all of which reduce our cost of services.

CA-NA cost of service revenue increased to ~~$38.0~~$37.7 million and ~~$74.7~~$112.4 million, respectively, for the three and ~~six~~nine month periods ended ~~June~~September 30, 2017, as compared with ~~$33.8~~$36.7 million and ~~$70.4~~$107.1 million, respectively, for the prior year periods, due to increases in ~~revenue share earned by our airline partners,~~ network operations expenses (including satellite service fees) and aircraft operations expenses. These increases were partially offset by increases in the amortization of our deferred airborne lease incentives, the recognition of monthly service fees and maintenance fees paid to us by certain of our airline partners, all of which reduce our cost of services. See Note 10, “Leases” into our unaudited condensed consolidated financial statements for additional information regarding our deferred airborne lease incentives.

BA cost of service revenue increased to ~~$9.9~~$10.1 million and ~~$19.4~~$29.5 million, respectively, for the three and ~~six~~nine month periods ended ~~June~~September 30, 2017, as compared with ~~$8.9~~$8.4 million and ~~$17.3~~$25.7 million, respectively, for the prior year periods. The increases were primarily due to increased ATG units online and an increase in the average network utilization per ATG unit online which resulted in higher ATG network service costs and, to a lesser extent, an increase in satellite service fees.

We expect cost of service revenue ~~in the near term~~ forCA-NA to increase atover time mainly due to increased satellite service fees for additional coverage. Additionally, we expect a slower rate than historically. Such expenses will include additional satellite coverage to support and/or supplement geographic areas we currently serve as well as new areas, offset in part by an increasedecrease in the amortization of deferred airborne lease ~~incentives. Over time, we expect total cost of service revenue inCA-NA~~ ~~to decline as a percentage of total service revenue~~incentives as we ~~realize efficiencies inherent in the scalability of~~anticipate our ~~business.~~airline agreements will transition from an operating lease or Turnkey model to a sale or Airline Directed model.

As we expand our business internationally, we also expect to incur additional cost of service revenue inCA-ROW, reflecting increased satellite usage, maintenance costs and network related expenses.

Cost of equipment revenue increased to ~~$14.6~~$15.3 million and ~~$26.3~~$41.6 million, respectively, for the three and ~~six~~nine month periods ended ~~June~~September 30, 2017, as compared with ~~$12.5~~$10.5 million and ~~$26.2~~$36.8 million, respectively, for the prior year periods. The increase occurred primarily within the BA segment and to a lesser extent theCA-ROW segment, offset in part by a decrease in theCA-NA segment. The increase in BA was due to an increase in inventory reserves on certain products, thewrite-off of capitalized software, changes in product mix and increases in warranty ~~expense and the~~expense. The increase inCA-ROW was due to ~~the~~ additional equipment transactions that qualify for sale treatment. The decrease inCA-NA was due to fewer equipment transactions that qualify for sale treatment. We expect that our cost of equipment revenue in future periods will vary with changes in equipment revenue.

Engineering, design and development expenses increased ~~44.4%~~21.2% and ~~55.2%~~43.0% to ~~$35.7~~$31.3 million and ~~$71.9~~$103.3 million, respectively, for the three and ~~six~~nine month periods ended ~~June~~September 30, 2017, as compared with ~~$24.7~~$25.8 million and ~~$46.4~~$72.2 million, respectively, for the prior year periods, due primarily to increases in ~~theCA-NA~~ ~~andCA-ROW~~ ~~segments. TheCA-NA~~ ~~andCA-ROW~~all three segments ~~increased~~ due to higher personnel expense and outside services in connection with the development of new products and technologies and obtaining STCs. Additionally, the increase in theCA-NA segment for the three and ~~six~~nine month periods was due to the recognition of ~~$2.4~~approximately $3 million and ~~$11.8~~$16 million, respectively, of expenses related to the development of our next generation ATG ~~solution.~~solution, primarily due to the achievement of major development milestones at different points during the year.

~~Excluding the next generation ATG development expenses, we expect engineering, design and development expenses to remain relatively consistent in future periods.~~ We expect consolidated engineering, design and development expenses to decrease as a percentage of consolidated revenue over time.

The increase in BA andCA-ROW was due primarily to an increase in personnel expense to support the growth of the businesses. Sales and marketing expenses as a percentage of total consolidated revenue decreased to ~~9.6%~~9.4% and 9.2%, respectively, for the three and ~~six~~nine month periods ended ~~June~~September 30, 2017, as compared with ~~11.4%~~10.1% and ~~10.9%~~10.6%, respectively, for the prior year periods.

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 bothCA-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 increased ~~5.2%~~11.1% and ~~6.3%~~7.9% to ~~$23.5~~$24.1 million and ~~$46.1~~$70.2 million, respectively, for the three and ~~six~~nine month periods ended ~~June~~September 30, 2017, as compared with ~~$22.4~~$21.7 million and ~~$43.4~~$65.0 million, respectively, for the prior year periods, due to increases in ~~theCA-NA~~ ~~andCA-ROW~~all three segments, ~~partially offset by a decrease~~due primarily to increases in ~~the BA segment.~~personnel expense. General and administrative expenses as a percentage of total consolidated revenue decreased to ~~13.6%~~13.9% and ~~13.6%~~13.7%, respectively, for the three and ~~six~~nine month periods ended ~~June~~September 30, 2017, as compared with ~~15.2%~~14.7% and ~~15.0%~~14.9%, respectively, for the prior year periods.

~~The increase in theCA-NA~~ ~~andCA-ROW~~ ~~segments’ general and administrative expenses for the three and six month periods ended June 30, 2017 from the prior year periods was due primarily to an increase in personnel related expenses.~~

The decrease in the BA segment’s general and administrative expenses for the three and six month periods ended June 30, 2017 from the prior year periods was due primarily to a decrease in personnel related expense.

We ~~expect our general and administrative expenses to remain relatively consistent in future periods. However, we~~ expect general and administrative expenses to decrease as a percentage of consolidated revenue as we realize economies of scale.

CA-NA’s segment profit ~~decreased 13.1% and 15.7%~~increased 10.0% to ~~$16.2~~$16.0 million ~~and $27.4 million, respectively,~~ for the three ~~and six~~ month ~~periods~~period ended ~~June~~September 30, 2017, as compared with ~~$18.6~~$14.5 million ~~and $32.5 million, respectively,~~ for the prior year ~~periods.~~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 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 inCA-NA’s segment profit for the ~~three and six~~nine month ~~periods~~period ended ~~June~~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, as discussed above.

BA’s segment profit increased ~~32.5%~~3.3% and ~~30.8%~~21.3% to ~~$25.2~~$21.3 million and ~~$51.3~~$72.6 million, respectively, for the three and ~~six~~nine month periods ended ~~June~~September 30, 2017, as compared with ~~$19.0~~$20.7 million and ~~$39.2~~$59.9 million, respectively, for the prior year periods. The increase in BA’s segment profit for the three and ~~six~~nine month periods ended ~~June~~September 30, 2017 was due to an increase in service revenue, partially offset by an increase in operating expenses, ~~and a decrease in equipment revenue,~~ as discussed above.

CA-ROW’s segment loss increased ~~34.8%~~21.0% and ~~34.7%~~30.4% to ~~$31.4~~$24.1 million and ~~$58.0~~$82.1 million, respectively, for the three and ~~six~~nine month periods ended ~~June~~September 30, 2017, as compared with ~~$23.3~~$19.9 million and ~~$43.0~~$62.9 million, respectively, for the prior year periods. The increase inCA-ROW’s segment loss for the three and ~~six~~nine month periods ended ~~June~~September 30, 2017 was due to an increase in operating expenses, offset in part by an increase in service and equipment revenue, as discussed above.

Depreciation and amortization expense increased ~~22.7%~~33.8% and ~~23.8%~~27.3% to ~~$30.6~~$35.8 million and ~~$61.0~~$96.8 million, respectively, for the three and ~~six~~nine month periods ended ~~June~~September 30, 2017, as compared with ~~$24.9~~$26.8 million and ~~$49.3~~$76.0 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.~~segments and accelerated depreciation expense for certain upgrade and decommission programs. See Note 1, “Basis of Presentation” to our unaudited condensed consolidated financial statements for additional information on the accelerated depreciation expense.

We expect our depreciation and amortization expense to increase in future periods as we install our equipment on additional aircraft, install more expensive satellite-based equipment on aircraft and further expand our ground and satellite networks.

Other (income) expense and percent change for the three and ~~six~~nine month periods ended ~~June~~September 30, 2017 and 2016 were as follows(in thousands, except for percent change):

Total	$	52,947		$	48,084			10.1	%	$	80,077		$	72,114			11.0	%

Total other expense was ~~$26.5~~$27.1 million and ~~$52.9~~$80.1 million, respectively, for the three and ~~six~~nine month periods ended ~~June~~September 30, 2017, as compared to ~~$32.9~~$24.0 million and ~~$48.1~~$72.1 million, respectively, for the prior year periods. Interest expense increased during the three and ~~six~~nine month periods ended ~~June~~September 30, 2017 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 ~~six~~nine month periods ended ~~June~~September 30, 2017, as compared to the prior year periods, was due to the issuance of the Original Senior Secured Notes in June 2016, ~~and~~ 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 ~~three and six~~nine month ~~periods~~period ended ~~June~~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.

We expect our interest expense to increase ~~in 2017 as compared with 2016~~ due to higher average debt outstanding and higher average interest rates ~~in 2017 as compared to 2016~~ because of the issuance of the Senior Secured Notes. Interest expense will also increase due to a full year of amortization of deferred financing fees associated with the Senior Secured Notes offset in part by the amortization of the debt premium associated with the Senior Secured Notes. These increases will be partially offset by the extinguishment of the Amended and Restated Senior Term Facility. See Note 8, “Long-Term Debt and Other Liabilities,” in our unaudited condensed consolidated financial statements for additional information.

The effective income tax rate for the three and ~~six~~nine month periods ended ~~June~~September 30, 2017 and 2016 was (0.8%) and (0.7%), respectively, as compared with ~~(0.6%~~(1.4%) and ~~(0.8%~~(1.0%), respectively, for the prior year periods. Income tax expense recorded in each period was similar, with differences inpre-tax income causing the change in the effective tax rate. The difference between our effective tax rates and the U.S. federal statutory rate of 35% for the three and ~~six~~nine month periods ended ~~June~~September 30, 2017 and 2016 was primarily due to the recording of a valuation allowance against our net deferred tax assets.

We expect our income tax provision to increase in future periods to the extent we become profitable.

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.

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 of debt and (iv) adjustment of deferred financing costs. 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 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, “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, 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 to an understanding of our operating performance to exclude the loss on extinguishment of debt and adjustment of deferred financing costs from Adjusted EBITDA because of thenon-recurring nature of these charges.

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.

Supplemental information:
Short-term investments	$	283,241		$	378,673		$	188,496		$	338,725

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.

Although we can provide no assurances, we currently believe that cash, cash equivalents and short-term investments on hand as of ~~June~~September 30, 2017 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 ~~2Ku andATG-4~~airborne equipment on certain aircraft operated by our airline partners, continuing our international expansion and developing our next generation ATG solution. 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 ATG 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.

For additional information on our Senior Secured Notes, Convertible Notes, Amended and Restated Credit Agreement and Restricted Cash, please see Note 8, “Long-Term Debt and Other ~~Liabilities.”~~Liabilities” to our unaudited condensed consolidated financial statements.

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


							For the Nine Months

Net cash provided by operating activities	$	2,388		$	24,361
Net cash provided by (used in) operating activities							$	(4,209	)	$	45,148

For the ~~six~~nine month period ended ~~June~~September 30, 2017, cash used in operating activities was $4.2 million as compared with $45.1 million of cash provided by operating activities ~~was $2.4 million as compared with $24.4 million for~~in the prior year period. The principal contributors to the change in operating cash flows were:

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 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 ~~$55.2~~a cash inflow of $150.0 million and ~~$159.2~~a cash outflow $119.2 million, respectively, for the ~~six~~nine month period ended ~~June~~September 30, 2017 and 2016.

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

Cash used in financing activities for the ~~six~~nine month period ended ~~June~~September 30, 2016 was ~~$202.7~~$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 ~~$1.2~~$1.9 million.

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 ~~six~~nine month periods ended ~~June~~September 30, 2017 and 2016 were ~~$145.7~~$214.2 million and ~~$85.0~~$128.7 million, respectively. The increase in capital expenditures was primarily due to an increase in airborne equipment purchases (as airborne equipment represents approximately 70% of our capital expense for the current year), primarily for the rollout of 2Ku, and to a lesser extent an increase 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 our purchases of equipment in 2018 that, when sold to airlines, will qualify as sales rather than as operating leases of space on aircraft.

We have agreements with vendors to provide us with transponder and teleport satellite services. These agreements vary in length and amount and as of ~~June~~September 30, 2017 commit us to purchase transponder and teleport satellite services totaling approximately ~~$41.7~~$21.4 million in 2017 ~~(July~~(October 1 through December 31), ~~$72.9~~$75.6 million in 2018, ~~$79.1~~$81.9 million in 2019, ~~$85.4~~$86.2 million in 2020, $75.9 million in 2021 and $303.0 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, “Leases,” into 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, “Leases,” into 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 ~~rebates~~rebate of $1.8 million in June ~~2017 and June~~ 2018. ~~We paid the 2017 rebate on June 13, 2017.~~

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.

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 ~~June~~September 30, 2017 and December 31, 2016 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 ~~June~~September 30, 2017 and December 31, 2016 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 ~~six~~nine month periods ended ~~June~~September 30, 2017 and 2016 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.

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 ~~June~~September 30, 2017. 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 ~~June~~September 30, 2017.

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.

From time to time we may become involved in 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.

Except as set forth in our Quarterly Report on Form10-Q for the quarter ended March 31, 2017 as filed with the SEC on May 4, 2017, there have been no material changes to the risk factors previously disclosed in our 201610-K.

Pursuant to the requirements of the Securities and Exchange Act of 1934, as amended, the registrant has duly caused this report to be signed on its behalf by the undersigned thereunto duly authorized.
