Record quarterly revenue up 21 percent to $116 million

ITASCA, Ill., May 7, 2015 – Gogo Inc. (Nasdaq: GOGO), a leading global aero communications service provider, today announced its financial results for the quarter ended March 31, 2015.

Gogo reported record first quarter revenue of $115.5 million, up 21% year-over-year, as service revenue increased 32% to $95.4 million. Adjusted EBITDA rose 54% year-over-year to $8.2 million.

“Q1 was a very strong quarter for Gogo on many fronts. We delivered record financial results highlighted by strong revenue growth and increased profitability. We continued to bring more bandwidth to the sky as Delta Airlines, a long-term airline partner, selected our 2Ku satellite-based technology for 250 domestic and at least 25 new international aircraft. Finally, we are very pleased that the international airline community is increasingly recognizing our company’s global leadership,” said Gogo’s President and CEO, Michael Small.

Recent Developments

Business Outlook

For the full year ending December 31, 2015, we are reiterating our Adjusted EBITDA and Cash CAPEX guidance and incorporating the following change in our CA-ROW and, therefore, total revenue guidance.

Certain CA-ROW transactions previously forecast as revenue are being accounted for as a reduction to cost of service. We estimate this change to result in a $5 million reduction in both forecast revenue and cost of service revenue, with no impact to Adjusted EBITDA for the year. This $5 million change to CA-ROW revenue will also flow through to total revenue.

Accordingly, our full year guidance is as follows:

“We are very pleased with our strong financial performance,” said Gogo’s Executive Vice President and CFO, Norman Smagley. “These strong results and our increased liquidity position us very well to continue winning global share,” commented Mr. Smagley.

Non-GAAP Financial Measures

We report certain non-GAAP financial measurements, including Adjusted EBITDA, Adjusted Net Loss Per Share and Cash CAPEX in the supplemental tables 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. Management prepares Adjusted Net Loss Per Share for investors, securities analysts and other users of our financial statements for use in evaluating our performance under our current capital structure. 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 by other companies. Adjusted EBITDA, Adjusted Net Loss Per Share and Cash CAPEX are not recognized measurements under accounting principles generally accepted in the United States, or GAAP, and when analyzing our performance or liquidity, 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, and Adjusted Net Loss Per Share in addition to, and not as an alternative to, net loss attributable to common stock as a measure of operating results, and (iii) use Cash CAPEX in addition to, and not as an alternative to, consolidated capital expenditures when evaluating our liquidity.

Definition of Non-GAAP Measures

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

Adjusted EBITDA represents EBITDA adjusted for (i) stock-based compensation expense and (ii) amortization of deferred airborne lease incentives. 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 as determined using the Black-Scholes model 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 a non-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 2014 10-K for a discussion of the accounting treatment of deferred airborne lease incentives.

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.

Adjusted Net Loss Per Share represents net loss attributable to common stock per share—basic and diluted, adjusted to reflect the number of shares of common stock outstanding as of March 31, 2015 under our current capital structure, after giving effect to the shares of our common stock effectively repurchased as part of the Forward Transactions entered into in connection with the issuance of the Convertible Notes. We present Adjusted Net Loss Per Share to provide investors, securities analysts and other users of our financial statements with important supplemental information with which to evaluate our performance considering our current capital structure and the shares outstanding after giving effect to the Forward Transactions.

Cash CAPEX represents capital expenditures net of airborne equipment proceeds received from the airlines and incentives paid to us by landlords under certain facilities leases. 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.
