Gogo Announces First Quarter 2020 Financial Results May 11, 2020 Highlights Actions to Manage Impact of COVID-19 on Aviation Markets CHICAGO – Gogo (NASDAQ: GOGO), the leading global provider of broadband connectivity products and services for aviation, today announced its financial results for the quarter ended March 31, 2020. Q1 2020 Financial Highlights Consolidated revenue of $184.5 million; Net loss of $84.8 million, which includes charges of $46.4 million related to the impairment of certain long-lived assets and $6.8 million in additional credit loss reserves taken during the quarter. Adjusted EBITDA(1) of $25.7 million. BA Reportable Segment Profit of $35.9 million, up 6% from Q1 2019. Cash Flow from Operating Activities of $38.0 million; Free Cash Flow(1) of $22.7 million. Cash and cash equivalents were $214.2 million as of March 31, 2020, including $22 million drawn in March from the Company’s ABL Credit Facility. This compares to cash and cash equivalents of $170.0 million as of December 31, 2019. Reached 1,511 2Ku and 1,758 total CA satellite aircraft online as of March 31, 2020, with a backlog of ~800 2Ku aircraft(2). In Q1 2020, 2Ku aircraft online increased by 104. Summary of Actions in Response to COVID-19 Related Decline in Air Traffic On April 22, 2020, the Company announced comprehensive actions in response to the COVID-19 related decline in air traffic. These measures include: A furlough of approximately 54% of the workforce effective May 4, 2020. The furloughs impact approximately 600 employees across all three of Gogo’s business segments and corporate personnel. Compensation reductions for nearly all personnel not impacted by furlough, including 30% for the CEO and Board of Directors and 20% for the executive leadership team. Ongoing negotiations with suppliers and customers to improve contract terms, the delay of aircraft equipment installations, the deferral of capital equipment purchases, and the reduction of marketing, travel and non-essential spend. The submission of applications to the U.S. Treasury Department for an $81 million grant and a $150 million loan under the recently enacted CARES Act. If Gogo receives government assistance, it will modify the announced personnel actions to comply with the terms of that assistance. First Quarter 2020 Consolidated Financial Results Consolidated revenue of $184.5 million declined by 8% from Q1 2019. Service revenue of $150.8 million declined by 9% from Q1 2019, driven by a decline in CA-NA service revenue partially offset by growth in BA service revenue. Equipment revenue of $33.7 million declined 2% from Q1 2019, driven by a decline in BA equipment revenue offset by growth in both CA-NA and CA-ROW equipment revenue. Net loss of $84.8 million increased from a net loss of $16.8 million in Q1 2019, due primarily to a $46.4 million charge related to impairment of long-lived assets and lower Adjusted EBITDA. Adjusted EBITDA decreased to $25.7 million, down from $38.0 million in Q1 2019, primarily due to lower CA-NA segment profit partially offset by improved BA segment profit. Adjusted EBITDA includes a $6.8 million charge for expected credit losses due primarily to the impact of COVID-19, largely from one international airline partner. “We started the year well ahead of plan, but Commercial Aviation demand fell sharply in March due to COVID-19 and has deteriorated further in Q2,” said Oakleigh Thorne, Gogo’s President and CEO. “There has also been a slowdown in new activations and an increase in account suspensions in our Business Aviation segment, which we expect will negatively impact BA revenue in Q2.” “The Gogo team responded quickly to COVID-19 with actions to reduce costs, maintain our strong global franchise and ensure our long-term financial viability,” Thorne said. “I think we are well positioned to get through this crisis and am extremely proud of the efforts and sacrifices of our Gogo team in these difficult times.” “To ensure our long-term liquidity, we are aggressively executing on our previously announced 16 levers to manage costs,” said Barry Rowan, Gogo’s Executive Vice President and CFO. “Our stronger than expected cash position exiting 2019 and through the first four months of 2020 has positioned us to manage through this difficult period and we are committed to continuing this heightened level of financial and operational discipline.” First Quarter 2020 Business Segment Financial Results Business Aviation (BA) Total revenue increased to $70.9 million, up 1% from Q1 2019, driven by 8% service revenue growth offset by a decline in equipment revenue. Service revenue increased to $57.7 million, up 8% from Q1 2019, driven by a 7% increase in ATG units online and a more than 2% increase in average monthly service revenue per ATG unit online. Equipment revenue decreased to $13.2 million, down 24% from Q1 2019, due to lower ATG and satellite unit shipments. Reportable segment profit increased to $35.9 million, up 6% from Q1 2019, with a reportable segment profit margin of nearly 51%. Q1 2020 reportable segment profit margin was an all-time quarterly record for BA, driven largely by higher service gross margin. Commercial Aviation - North America (CA-NA) Total revenue decreased to $80.1 million, down 17% from Q1 2019. Service revenue decreased to $73.8 million, down 20% from Q1 2019, primarily due to the impact of COVID-19, the full impact of American Airlines switching to the airline-directed model, the deinstallation of Gogo equipment from certain American Airlines aircraft during 2018 and the first half of 2019, and the recognition of product development-related revenue from one of our airline partners in the first quarter of 2019. Equipment revenue increased to $6.3 million, up 56% from Q1 2019, due primarily to more installations under the airline-directed model. Reportable segment profit decreased to $15.9 million, down 48% from Q1 2019, due to lower service revenue partially offset by a combined 32% decline in engineering, design and development, sales and marketing and general and administrative expenses. Aircraft online increased to 2,480 as of March 31, 2020 from 2,412 as of March 31, 2019, due to an increase in 2Ku and ATG aircraft partially offset by the previously planned removal of older mainline ATG aircraft from airlines’ operating fleets. Take rates declined to 13.3% in Q1 2020, down from 13.9% in Q1 2019. Q1 2020 take rates were above the average take rate of 13.2% in 2019. Net annualized ARPA decreased to $99,000, down from $126,000 in Q1 2019, due to the full impact of American Airlines transition to the airline-directed model, product development-related revenue in the first quarter of 2019 and the impact of COVID-19. Commercial Aviation - Rest of World (CA-ROW) Total revenue increased to $33.4 million, up 1% from Q1 2019. Service revenue decreased to $19.2 million, down 3% from Q1 2019, due to lower ARPA caused by the negative effect of COVID-19 on global commercial air travel partially offset by an increase in aircraft online. Equipment revenue increased to $14.2 million, up 8% from Q1 2019, due to an increase in spare parts sold under the airline-directed model, partially offset by fewer installations under the airline-directed model. Reportable segment loss improved to $17.4 million, a 4% improvement from Q1 2019, due to declines in cost of equipment revenue, engineering, design and development expenses, and sales and marketing expenses partially offset by an increase in general and administrative expenses which was primarily due to the establishment of credit loss reserves stemming from the impact of COVID-19, the majority of which related to a single international airline partner. The financial condition of this airline partner continued to deteriorate to the point of entering administration subsequent to March 31, 2020, which we expect will result in additional credit losses in Q2 2020. Aircraft online increased to 833 as of March 31, 2020, up from 641 as of March 31, 2019. Take rates declined to 12.3% in Q1 2020, down from 13.6% in Q1 2019. Net annualized ARPA of $97,000 in Q1 2020 declined from $136,000 in Q1 2019, due primarily to the growth in new aircraft fleets online, which typically initially generate lower net annualized ARPA, and 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 March 31, 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. Business Aviation For the Three Months Ended March 31, 2020 2019 Aircraft online (at period end) Satellite 4,939 5,135 ATG 5,713 5,348 Average monthly service revenue per aircraft online Satellite $ 223 $ 237 ATG 3,143 3,071 Units Sold Satellite 56 130 ATG 125 187 Average equipment revenue per unit sold (in thousands) Satellite $ 60 $ 40 ATG 77 61 Satellite aircraft online. We define satellite aircraft online as the total number of business aircraft for which we provide satellite services as of the last day of each period presented. ATG aircraft online. We define ATG aircraft online as the total number of business aircraft for which we provide ATG services as of the last day of each period presented. Average monthly service revenue per satellite aircraft online. We define average monthly service revenue per satellite aircraft online as the aggregate satellite service revenue for the period divided by the number of months in the period, divided by the number of satellite aircraft online during the period (expressed as an average of the month-end figures for each month in such period). Average monthly service revenue per ATG aircraft online. We define average monthly service revenue per ATG aircraft online as the aggregate ATG service revenue for the period divided by the number of months in the period, divided by the number of ATG aircraft online during the period (expressed as an average of the month-end figures for each month in such period). Units sold. We define units sold as the number of satellite or ATG units for which we recognized revenue during the period. Average equipment revenue per satellite unit sold. We define average equipment revenue per satellite unit sold as the aggregate equipment revenue earned from all satellite units sold during the period, divided by the number of satellite units sold. Average equipment revenue per ATG unit sold.

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 and (vi) 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 15, “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 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.
