SES S.A. (OTC:SGBAF) is one of the fastest-growing space stocks to buy now. On June 1, SES launched a multi-orbit satellite in-flight connectivity service on Viva’s Airbus aircraft, expanding its aviation broadband presence in the Americas. The deployment is set to cover 60 A320s and 40 A321s in the coming years, with Viva becoming the first Mexico-based airline to use SES’s new electronically steered array antenna connected to the company’s multi-orbit network.

The aviation focus connects directly to SES’s latest growth numbers. On May 12, the company reported first-quarter 2026 revenue of €847 million, up 80.5% year over year at constant currency on a reported basis, helped by the consolidation of Intelsat. Like-for-like revenue grew 3.1%, while Networks revenue rose 106.0% and Mobility revenue increased 207.8% on a reported basis. That makes Viva relevant not just as a customer win, but as part of the segment driving SES’s top-line expansion.
