CHICAGO, Feb. 21, 2019/PRNewswire / -- Gogo (NASDAQ: GOGO), the leading global provider of broadband connectivity products and services for aviation, today announced its financial results for the quarter ended December 31, 2018.

Fourth Quarter 2018 Consolidated Financial Results

• Consolidated revenue increased to $217.2 million.
• • Service revenue of $160 milliondeclined 2% from Q4 2017, primarily related to the de-installations of American Airlines ATG aircraft, totaling 375 at the end of 2018, and the change in business terms associated with their transition to an airline-directed business model. Hereinafter, we refer to these items as the 'de-installations.'
  • Equipment revenue increased to $57.2 million, up from $24 millionin Q4 2017, primarily due to the post-adoption impact of ASC 606.
• Net loss of $59.7 millionincludes a $19.7 millionloss on the extinguishment of debt.
• Adjusted EBITDA⁽¹⁾ decreased to $19.4 million, down 22% from Q4 2017, primarily related to the de-installations.
• Capital expenditures decreased to $7.3 million, down from $66.0 millionin Q4 2017.
• Cash CAPEX⁽¹⁾ decreased to $2.4 millionfrom $43.1 millionin Q4 2017, driven by an increase in installations under the airline-directed model.
• Cash, cash equivalents and short-term investments were $223.5 millionas of December 31, 2018, substantially higher than previous expectations.

'Gogo's focus on execution resulted in major operational improvements over the course of 2018, including excellent 2Ku performance and aggressive cost controls within our CA business,' said Oakleigh Thorne, Gogo's President and CEO. 'As we build on this momentum and put the negative effects of the de-installations behind us over the next several quarters, we expect to see a return to higher revenue and profit growth in 2020.'

'Strong execution led to fourth quarter financial performance coming in well ahead of our internal projections, particularly for Adjusted EBITDA and our year-end cash balance,' said Barry Rowan, Gogo's Executive Vice President and CFO. 'We expect to improve Free Cash Flow by approximately $100 millionin 2019 as we continue to grow Adjusted EBITDA and improve working capital.'

Fourth Quarter 2018 Business Segment Financial Results

Business Aviation (BA)

• Total revenue increased to $73.6 million, up 11% from Q4 2017.
• Service revenue increased to $51.3 million, up 13% from Q4 2017, driven by a 12% increase in ATG units online and a 3% increase in average monthly service revenue per ATG unit online.
• Equipment revenue increased to $22.3 million, up 8% from Q4 2017, driven by continuing strong demand for AVANCE L5 and L3 systems.
• Segment profit increased to $35.6 million, up 33% compared to the prior year period, with segment profit margin of 48%, up from 41% in the prior year period.

Commercial Aviation - North America(CA-NA)

• Take rates increased to 12.9% in Q4 2018 up from 9.9% in the prior year period.
• Primarily as a result of the de-installations discussed above:
• • Total revenue decreased to $97.3 millionfrom $105.1 million, down 7% from Q4 2017.
  • Service revenue decreased to $89.4 million, down 13% from Q4 2017.
  • Aircraft online decreased 10% to 2,551 on December 31, 2018from 2,840 on December 31, 2017.

• Equipment revenue increased to $7.9 million, up from $1.9 millionin Q4 2017, due to the post-adoption impact of ASC 606.
• Segment profit decreased to $8.8 millionfrom $23.5 millionin Q4 2017, due to the effect of the de-installations and higher satcom expense.

Commercial Aviation - Rest of World (CA-ROW)

• Total revenue increased to $46.4 million, up from $16.9 millionin Q4 2017.

• Net annualized ARPA of $144,000in Q4 2018 declined from $183,000in the prior year period, due primarily to the significant growth in new aircraft fleets online, which typically initially generate lower net annualized ARPA.
• Segment loss of $24.7 milliondeclined slightly versus Q4 2017 as higher equipment losses were offset by an increase in 2Ku aircraft online.

Full-Year 2018 Consolidated Financial Results

• Consolidated revenue increased to $893.8 million.
• • Service revenue increased to $630.1 million, up 2% from 2017, due to growth in our BA segment, that was partially offset by the decline in CA NA service revenue driven by the de-installations.

• Adjusted EBITDA⁽¹⁾ increased to $71.2 million, up 22% from $58.5 millionin 2017, related primarily to strong results in our BA segment and, secondarily, related to decreased losses in the ROW segment.
• Capital expenditures decreased to $131.7 millionin 2018 from $280.2 millionin 2017.
• Cash CAPEX⁽¹⁾ decreased to $107.6 millionfrom $220.5 millionin 2017, driven by an increase in installations under the airline-directed model.

Recent Developments

• On December 6, 2018, Gogo closed its offering of $238 millionof 6% convertible senior notes due in May 2022. This effectively extended the maturity of approximately $200 millionof our outstanding convertible senior notes from March 2020until May 2022.
• Gogo surpassed 1,000 2Ku aircraft online and ended 2018 with nearly 1,300 commercial aircraft installed with satellite IFC systems and approximately 1,000 2Ku aircraft in backlog as of December 31, 2018.
• As of February 20, 2019, Gogo had experienced no incidents of 2Ku system degradation on aircraft fitted with Gogo's recent de-icing modifications. Gogo estimates that aircraft with Gogo de-icing modifications have now flown 15,000 flights that had been de-iced, based on Federal Aviation Administration (FAA) data listing airports under de-icing conditions.
• The Airbus A220 has now entered revenue service with Delta offering both 2Ku and Gogo Vision Touch.
• Gogo completed its first satellite IFC installation on a Boeing 787-800 aircraft using a service bulletin.
• As of February 6, 2019, BA had shipped more than 770 AVANCE systems (L3 and L5) with over 500 L5 systems installed and in operation.

Business Outlook
The Company provides its 2019 financial guidance as follows:

• Total consolidated revenue of $800 millionto $850 million
• • CA-NA revenue of $355 millionto $380 million, with ~10% from equipment revenue
  • CA-ROW revenue of $135 millionto $150 million, with ~30% from equipment revenue
  • BA revenue of $310 millionto $320 million

Note that CA equipment revenue is affected by the number of installations completed under the airline-directed business model in the period. 2019 revenue guidance reflects the impact of one airline switching from the airline-directed business model to the turnkey business model, which will reduce equipment revenue.

• Adjusted EBITDA⁽¹⁾ of $75 millionto $95 million
• $100 millionimprovement in Free Cash Flow⁽¹⁾ versus 2018
• Increase of 400 to 475 in 2Ku aircraft online

The Company will host its fourth quarter conference call on February 21, 2019at 8:30 a.m. ET. A live webcast of the conference call, as well as a replay, will be available online on the Investor Relations section of the Company's website at http://ir.gogoair.com.

Non-GAAP Financial Measures

We report certain non-GAAP financial measurements, including Adjusted EBITDA, Cash CAPEX and Free Cash Flow in the supplemental tables below. Management uses Adjusted EBITDA, Cash CAPEX and 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, Cash CAPEX and 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 Cash CAPEX or 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, (iii) use Cash CAPEX in addition to, and not as an alternative to, consolidated capital expenditures when evaluating our liquidity and (iv) use 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. No reconciliation of the forecasted range for Adjusted EBITDA and Free Cash Flow for fiscal 2019 is included in this release because we are unable to quantify certain amounts that would be required to be included in the corresponding GAAP measure without unreasonable efforts and we believe such reconciliation would imply a degree of precision that would be confusing or misleading to investors. In particular, we are not able to provide a reconciliation for the forecasted range of Adjusted EBITDA due to variability in the timing of aircraft installations and deinstallations impacting depreciation expense and amortization of deferred airborne leasing proceeds.

• Aircraft online. We define aircraft online as the total number of commercial aircraft on which our equipment is installed and service has been made commercially available as of the last day of each period presented. We assign aircraft 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 Americaat 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.
• 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 costs which are included in cost of service revenue for that segment, divided by the number of months in the period, and further divided by the number of aircraft equivalents (as defined above) for that segment during the period, which is then annualized and rounded to the nearest thousand. Beginning with the three month period ended March 31, 2018, we changed the calculation of ARPA to be net of revenue share expense and other transactional expenses in order to better reflect the financial statement impact of revenues generated under both the turnkey model and airline-directed model. The amounts reported above for the year ended December 31, 2017reflect this change in methodology. ARPA for the CA-NA segment for the three months and year ended December 31, 2017was originally reported as $144 thousandand $140 thousand, respectively. ARPA for the CA-ROW segment for the three month and year ended December 31, 2017was originally reported as $201 thousandand $214 thousand, respectively.

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, (ii) amortization of deferred airborne lease incentives, (iii) amortization of STC costs, (iv) the accounting impact of the transition to the airline-directed model and (v) loss on extinguishment of debt. 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 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 and amortization of STC costs from Adjusted EBITDA is useful as it allows an investor to view operating performance across time periods in a manner consistent with how management measures segment profit and loss. Management evaluates segment profit and loss in this manner, excluding the amortization of deferred airborne lease incentives and amortization of STC costs, because such presentation reflects operating decisions and activities from the current period, without regard to the prior period decision or the form of connectivity agreements.

We believe it is useful for an understanding of our operating performance to exclude the accounting impact of the transition by one of our airline partners to the airline-directed model and the loss on extinguishment of debt from Adjusted EBITDA because of the non-recurring nature of these activities.

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. Historically, Cash CAPEX provided 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. This metric was used through 2018. However, going forward, we have determined that Free Cash Flow provides more meaningful information regarding the Company's liquidity. Accordingly, 2019 guidance for Free Cash Flow has been provided and Cash CAPEX will no longer be reported as a Non-GAAP measure.

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 Free Cash Flow provides meaningful information regarding the Company's liquidity.
