Annual Adjusted EBITDA margin rising from 40% in 2021 to 45% in 2025

Introducing 2025 Free Cash Flow Target of approximately $200 million

CHICAGO – September 28, 2021 – Gogo Inc. (NASDAQ: GOGO), the world’s largest provider of broadband connectivity services for the business aviation market, today announced that it has increased the long-term financial targets that were originally provided on its fourth quarter 2020 earnings conference call.

The Company will host a conference call with financial analysts at 8:00 a.m. ET on September 30, 2021 to discuss Gogo’s strategic plans, its competitive position and the increased forecast.

Revised Long-Term Financial Targets

“Growth in private air travel continues to expand, fueling what we expect will be sustained growth in demand for inflight connectivity as customers seek to replicate their home and office connectivity in the air,” said Oakleigh Thorne, Chairman and CEO of Gogo. “That has driven record equipment sales at Gogo and is expected to generate growth in high-margin service revenue through our 2025 planning horizon.”

“We recently updated our long-term financial model to reflect the impact of our plans to capitalize on these trends and we look forward to discussing them on our upcoming investor call,” Thorne said.

Non-GAAP Financial Measures

This press release includes financial measures and terms, including Adjusted EBITDA margin and Free Cash Flow, not calculated in accordance with accounting principles generally accepted in the United States (GAAP). Management uses Adjusted EBITDA margin 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.

We define Adjusted EBITDA margin as EBITDA (defined as net income (loss) attributable to common stock before interest expense, interest income, income taxes and depreciation and amortization expense), adjusted for items that management believes have less bearing on our operating performance, including stock-based compensation expense, over revenue. Our management believes that the use of Adjusted EBITDA margin 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 define Free Cash Flow as net cash provided by operating activities, less purchases of property and equipment and the acquisition of intangible assets. We believe that Free Cash Flow provides meaningful information regarding our liquidity.

No reconciliation of the forecasted range for Adjusted EBITDA margin for the 2021-2025 period or Free Cash Flow for 2023 or 2025 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.
