For Gogo Inc. (NASDAQ:GOGO), the investment question is increasingly about a fleet handover. The company's older air-to-ground (ATG) network, which connects business jets through cell towers, is shrinking, while its newer Galileo satellite service is only beginning to scale. On October 13, 2026, Gogo said Duncan Aviation, a large business jet service provider, placed a prepaid order for 40 Galileo HDX systems, described as its largest single maintenance-provider order this year. Shares closed that day at $2.175, down 10.86%, according to market data.

A Fleet in Transition

In its second-quarter 2026 results, published August 6, Gogo reported 5,731 ATG aircraft online, down 15% from a year earlier and 6% from the prior quarter. Galileo aircraft online rose to 184 from 111 at the end of March, a 66% increase, and cumulative Galileo shipments reached 518 units, with 108 shipped in the quarter. Business aviation service revenue was $151.3 million, down 8% year on year, while military and government service revenue rose 40% to $39.9 million. Total revenue was $222.8 million and the company reported a net loss of $2.0 million.

Dealers and Guidance

The key driver is whether Galileo installations can grow faster than ATG aircraft leave the network, since each ATG customer generates recurring service revenue that a 15% decline erodes. Management guided 2026 revenue of $870 million to $895 million, adjusted EBITDA of $175 million to $185 million and free cash flow of $65 million to $85 million. Regulatory approvals for HDX on aircraft such as the Gulfstream G650 and Pilatus PC-12 widen the addressable fleet, and dealer orders like Duncan's could mean more units flowing into aircraft over coming quarters, though timing and pricing were not disclosed.

Two Businesses, Opposite Directions

Gogo's recent data show two businesses moving in opposite directions: a shrinking ATG base and a Galileo base that is small but growing quickly. The Duncan order is a positive operating signal, but a single order does not settle whether the transition will outrun attrition, a question the next earnings report, estimated for November 5, may help answer.
