ViaSat Announces Second Quarter Fiscal Year 2016 Results

CARLSBAD, Calif., – November 9, 2015 – ViaSat Inc. (NASDAQ: VSAT), a global broadband services and technology company, today announced financial results for the fiscal second quarter ended September 30, 2015.

“We made great progress in our second quarter in terms of business accomplishments and financial results that highlight our success in delivering solid earnings growth through higher value service offerings in both consumer and mobile broadband markets,” said Mark Dankberg, ViaSat chairman and CEO. “Our strong core Adjusted EBITDA growth for the quarter and year-to-date, have been led by exceptional Satellite Services performance and double digit Government Systems growth despite an extremely challenging macro environment.”

“Additionally, our partnership with Virgin America bringing Netflix to air travelers took flight in the quarter, demonstrating that video is the litmus test for in-flight internet service,” Dankberg continued. “JetBlue’s upcoming video streaming partnership with Amazon will show we can uniquely scale video streaming at a time when airlines are beginning to see the benefits of delighting passengers with high-quality connectivity. With about 1,100 aircraft in total enabled with our in-flight internet service, we have network flexibility and scale to ensure the highest quality streaming experiences at 35,000 feet – with speeds reaching upwards of 20Mbps per device. This experience is proven daily on JetBlue, Virgin America and United Airlines with as many as 148 simultaneous active devices, and many of those using streaming media, on any given flight across our entire network. We’ve also seen similarly strong results in performance on flight tests for government applications.”

Use of Non-GAAP Financial Information

To supplement ViaSat’s consolidated financial statements presented in accordance with generally accepted accounting principles (GAAP), ViaSat uses non-GAAP net income (loss) attributable to ViaSat Inc. and Adjusted EBITDA, measures ViaSat believes are appropriate to enhance an overall understanding of ViaSat’s past financial performance and prospects for the future. We believe the non-GAAP results provide useful information to both management and investors by excluding specific expenses that we believe are not indicative of our core operating results. In addition, since we have historically reported non-GAAP results to the investment community, we believe the inclusion of non-GAAP numbers provides consistency in our financial reporting and facilitates comparisons to the Company’s historical operating results. Further, these non-GAAP results are among the primary indicators that management uses as a basis for evaluating the operating performance of our segments, allocating resources to such segments, planning and forecasting in future periods.
