August 24, 2023 – Viasat Inc. confirmed that its Inmarsat-6 F2 (I6 F2) satellite, which was launched on February 18, 2023, has suffered a power subsystem anomaly during its orbit raising phase. At this stage, Viasat and Airbus, the satellite’s manufacturer, are working to determine the root cause of the anomaly and assess whether the satellite will be able to perform its mission. Airbus has advised that this anomaly is an unprecedented event; none of its geostationary telecommunication satellites have ever suffered a failure in orbit. It is important to note that the I6 F2 anomaly does not impact ongoing customer services, and Viasat does not anticipate that it will materially affect the financial outlook for revenue and Adjusted EBITDA growth discussed in our letter to shareholders dated August 9, 2023. The manufacturing and launch costs of the I6 F2 satellite were insured and near-term cash positions are expected to improve. The twin Inmarat-6 F1 satellite (I6 F1), which was launched in December 2021, is operational and continues to perform as expected.
