Gogo Announces Second Quarter 2020 Financial Results August 10, 2020 CHICAGO – August 10, 2020 – Gogo (NASDAQ: GOGO), the leading global provider of broadband connectivity products and services for aviation, today announced its financial results for the quarter ended June 30, 2020. Q2 2020 Highlights Consolidated revenue of $96.6 million; Net loss of $86.0 million; Adjusted EBITDA(1) of negative $15.9 million. Combined engineering, design and development, sales and marketing and general and administrative expenses declined 27% from Q1 2020 and 35% from Q2 2019 reflecting aggressive cost control measures. BA Reportable Segment Profit of $27.2 million with nearly 50% segment profit margin. Cash and cash equivalents were $156.3 million as of June 30, 2020. This reflects $53 million of interest payments made in the second quarter and compares with total cash and cash equivalents of $214.2 million as of March 31, 2020. The Company achieved break-even unlevered Free Cash Flow for the quarter. The Company has retained investment bankers and is in a process to sell its CA division. Continuing Actions in Response to COVID-19 Related Decline in Air Traffic A recently announced reduction in force of 143 full-time positions predominately in the Commercial Aviation business, effective August 14, 2020. This follows our four-month furlough of over 50% of the workforce, or more than 600 employees. Ongoing compensation reductions for nearly all personnel not impacted by the furlough, including 30% for the CEO and Board of Directors and 20% for the executive leadership team. Continuing progress in negotiations with suppliers and customers to improve contract terms, delay aircraft equipment installations and defer capital equipment purchases. Continuing implementation of cost reduction initiatives which are expected to generate savings of more than $340 million through 2021, exceeding the high end of the previous forecast. Second Quarter 2020 Consolidated Financial Results Consolidated revenue of $96.6 million declined by 55% from Q2 2019 due to the impact of COVID-19 on demand for both domestic and international air travel. Service revenue of $74.3 million declined by 57% from Q2 2019, driven primarily by declines in CA-NA and CA-ROW service revenue and, to a lesser extent, BA service revenue. Equipment revenue of $22.4 million declined by 44% from Q2 2019, driven by reduced shipment and installation activity across all three segments. Net loss of $86.0 million increased from a net loss of $84.0 million in Q2 2019. Net loss in Q2 2019 included a loss on extinguishment of debt of $58.0 million. Adjusted EBITDA decreased to negative $15.9 million, down from positive $38.0 million in Q2 2019, due to lower segment profitability across all three segments. “While COVID-19 has significantly impaired global commercial aviation travel and our results for the second quarter, we are encouraged by the strong recovery in business aviation as well as the beginnings of a recovery in global commercial aviation which has continued into August,” said Oakleigh Thorne, Gogo’s President and CEO. “Going forward, we are focused on maintaining the strength of our franchise and realizing the value of CA through a potential sale of the division.” “By reducing spending and maintaining tight working capital management, we achieved break even, unlevered Free Cash Flow for the quarter, despite significantly lower revenue,” said Barry Rowan, Gogo’s Executive Vice President and CFO. “Execution of our cost-control plan resulted in a 35% year-over-year reduction in expenses in the second quarter. Through these efforts, we have further enhanced our ability to maintain adequate liquidity as we continue to navigate this challenging period.” Second Quarter 2020 Business Segment Financial Results Business Aviation (BA) Total revenue decreased to $54.6 million, down 23% from Q2 2019, driven by declines in both service and equipment revenue caused by the negative impact of COVID-19. Service revenue decreased to $44 million, down 20% from Q2 2019, resulting primarily from a 17% decrease in average monthly service revenue per ATG unit online. ATG aircraft online (AOL) declined 1% over the prior year period. Equipment revenue decreased to $10.6 million, down 36% from Q2 2019, due primarily to lower ATG unit shipments. Combined engineering, design and development, sales and marketing and general and administrative expenses decreased to $10.9 million, down 30% from Q2 2019. Reportable segment profit decreased to $27.2 million, down 13% from Q2 2019, with a reportable segment profit margin of nearly 50%. Commercial Aviation - North America (CA-NA) Total revenue decreased to $30 million, down 72% from Q2 2019. Service revenue decreased to $25.5 million, down 74% from Q2 2019, due to lower average revenue per aircraft (ARPA) caused by the negative effect of COVID-19 on North American air travel and to a lesser extent to the full impact of American Airlines switching to the airline-directed model and the deinstallation of Gogo equipment from certain American Airlines aircraft during 2018 and the first half of 2019. Equipment revenue decreased to $4.5 million, down 52% from Q2 2019, primarily due to fewer installations under the airline-directed model. Reportable segment loss was $10.6 million compared to segment profit of $34.1 million in Q2 2019 due to lower revenue partially offset by a 47% decline in combined engineering, design and development, sales and marketing and general and administrative expenses. Aircraft online increased to 2,455 as of June 30, 2020 from 2,443 as of June 30, 2019, due to an increase in 2Ku aircraft partially offset by the removal of older mainline ATG aircraft from airlines’ operating fleets. Net annualized ARPA decreased to $37 thousand from $136 thousand in Q2 2019, primarily due to the impact of COVID-19. Commercial Aviation - Rest of World (CA-ROW) Total revenue decreased to $12.0 million, down 67% from Q2 2019. Service revenue decreased to $4.7 million, down 79% from Q2 2019, due to lower average revenue per aircraft (ARPA) caused by the negative effect of COVID-19 on global commercial air travel partially offset by an increase in aircraft online. Equipment revenue decreased to $7.3 million, down 49% from Q2 2019, primarily due to fewer installations under the airline-directed model. Reportable segment loss increased to $26.7 million, a 63% increase from a loss of $16.4 million in Q2 2019, due to revenue declines and additional credit loss reserves stemming from the impact of COVID-19, reflected in an increase in general and administrative costs, partially offset by reductions in equipment, engineering, design and development, and sales and marketing expenses. Aircraft online increased to 842 as of June 30, 2020, up from 691 as of June 30, 2019. Net annualized ARPA of $25 thousand in Q2 2020 declined from $135 thousand in Q2 2019, due primarily to the negative effect of COVID-19 on global commercial air travel.

Non-GAAP Financial Measures We report certain non-GAAP financial measurements, including Adjusted EBITDA, Free Cash Flow and Unlevered Free Cash Flow in the supplemental tables below. Management uses Adjusted EBITDA, Free Cash Flow and Unlevered Free Cash Flow 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 by non-operational and unusual or non-recurring items. These supplemental performance measurements may vary from and may not be comparable to similarly titled measures used by other companies. Adjusted EBITDA, Free Cash Flow and Unlevered Free Cash Flow are not recognized measurements under accounting principles generally accepted in the United States, or GAAP; when analyzing our performance with Adjusted EBITDA or liquidity with Free Cash Flow or Unlevered Free Cash Flow, as applicable, investors should (i) evaluate each adjustment in our reconciliation to the corresponding GAAP measure, 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 Free Cash Flow or Unlevered Free Cash Flow in addition to, and not as an alternative to, consolidated net cash provided by (used in) operating activities when evaluating our liquidity.

We define aircraft online as the total number of commercial aircraft on which our equipment is installed and service has been made commercially available as of the last day of each period presented. We assign aircraft to CA-NA or CA-ROW at the time of contract signing as follows: (i) all aircraft operated by North American airlines and under contract for ATG or ATG-4 service are assigned to CA-NA, (ii) all aircraft operated by North American airlines and under a contract for satellite service are assigned to CA-NA or CA-ROW based on whether the routes flown by such aircraft under the contract are anticipated to be predominantly within or outside of North America at the time the contract is signed, and (iii) all aircraft operated by non-North American airlines and under a contract are assigned to CA-ROW. All aircraft online for the CA-ROW segment are equipped with our satellite equipment. We are aware that, beginning March 2020 and continuing through the date of this filing, our airline partners have parked a significant number of aircraft due to the impact of COVID-19 on the aviation industry. We do not know the specific number of such parked aircraft. The CA-NA and CA-ROW aircraft online disclosed above as of June 30, 2020 still include such aircraft, which is consistent with our historical practice of not removing temporarily parked aircraft from the online count as those have historically been immaterial and temporary. Should the duration of the aircraft being parked extend deeper into 2020, we may revisit this methodology for counting aircraft online. Aircraft equivalents. We define aircraft equivalents for a segment as the number of commercial aircraft online (as defined above) multiplied by the percentage of flights flown by such aircraft within the scope of that segment, rounded to the nearest whole aircraft and expressed as an average of the month-end figures for each month in the period. This methodology takes into account the fact that during a particular period certain aircraft may fly routes outside the scope of the segment to which they are assigned for purposes of the calculation of aircraft online. Net annualized average monthly service revenue per aircraft equivalent (“ARPA”). We define net annualized ARPA as the aggregate service revenue plus monthly service fees, some of which are reported as a reduction to cost of service revenue for that segment for the period, less revenue share expense and other transactional expenses which are included in cost of service revenue for that segment, divided by the number of months in the period, and further divided by the number of aircraft equivalents (as defined above) for that segment during the period, which is then annualized and rounded to the nearest thousand.

Definition of Non-GAAP Measures: EBITDA represents net loss attributable to common stock before interest expense, interest income, income taxes and depreciation and amortization expense. Adjusted EBITDA represents EBITDA adjusted for (i) stock-based compensation expense, (ii) amortization of deferred airborne lease incentives, (iii) amortization of STC costs, (iv) impairment of long-lived assets, (v) impairment of cost-basis investment, (vi) loss on extinguishment of debt and (vii) proceeds from litigation settlement. 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 that 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 that 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 a non-GAAP financial measure that excludes these costs and that management uses to evaluate our business. We believe that the exclusion of the amortization of deferred airborne lease incentives and amortization of STC costs from Adjusted EBITDA is useful as it allows an investor to view operating performance across time periods in a manner consistent with how management measures reportable segment profit and loss (see Note 16, “Business Segments and Major Customers,” for a description of reportable segment profit (loss) in our unaudited condensed consolidated financial statements). Management evaluates reportable segment profit and loss in this manner, excluding the amortization of deferred airborne lease incentives and amortization of STC costs, because such presentation reflects operating decisions and activities from the current period, without regard to the prior period decisions or the business model applicable to various connectivity agreements. We believe that the exclusion of the impairment of long-lived assets from Adjusted EBITDA is appropriate because of the non-recurring nature of the activity to our operating performance. We believe that the exclusion of the impairment of cost-basis investment from Adjusted EBITDA is appropriate because of the non-operating and non-recurring nature of the activity. We believe it is useful for an understanding of our operating performance to exclude the loss on extinguishment of debt from Adjusted EBITDA because of the non-recurring nature of this activity. We believe that the exclusion of litigation proceeds from Adjusted EBITDA is appropriate as this is non-recurring in nature and represents an infrequent financial benefit to our operating performance. 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. Free Cash Flow represents net cash provided by (used in) operating activities, less purchases of property and equipment and the acquisition of intangible assets. We believe that Free Cash Flow provides meaningful information regarding the Company’s liquidity. Unlevered Free Cash Flow represents Free Cash Flow adjusted for cash interest payments and interest income. We believe that Unlevered Free Cash Flow provides an additional view of the Company’s liquidity, excluding the impact of our capital structure.
