Broomfield, Colo. / 13 October 2026 – Gogo (NASDAQ: GOGO) today announced that Duncan Aviation, the world’s largest privately-owned business jet service provider, has placed a prepaid order for 40 Gogo Galileo HDX systems, marking Gogo’s largest single MRO order this year. The investment reflects anticipated customer demand for Gogo Galileo’s best-in-class connectivity and Duncan Aviation’s commitment to making its leading performance and reliability readily available to aircraft owners and operators.

“As expectations around inflight connectivity rise, we anticipate growing demand for Gogo Galileo HDX and are ready to support it,” says Nate Klenke, Duncan Aviation’s Modifications Sales Manager. “Having equipment on hand gives us greater flexibility to plan installations around our customers’ schedules. We have confidence in the technology and in Gogo’s ability to support our team and customers over the long term.”

Gogo has prioritised a reliable supply chain to ensure Galileo is readily available for customers planning installations. Gogo’s cybersecurity and data privacy protections, flexible financing, predictable service pricing and 24/7/365 multilingual support further reinforce this customer-first approach.

Powered by the Eutelsat OneWeb enterprise-grade low earth orbit (LEO) network, Gogo Galileo offers passengers and crew high-performance and reliable connectivity around the world. For owners and operators, it supports the growing expectation that time in the air can be as connected and productive as time on the ground. The HDX electronically steered antenna (ESA) provides a compact, lightweight, low power and high-performance solution that can be installed on light jets and turboprops, as well as larger-cabin aircraft.

“Duncan Aviation knows what owners and operators need from their connectivity, and we’re pleased to support its team as it brings the high performance Gogo Galileo to more aircraft,” says Michael Skou Christensen, Chief Revenue Officer for Gogo. “Our role is to offer reliable performance and remain available to customers throughout the life of the system, with experienced aviation teams, predictable service pricing and round-the-clock support.”
