"2025 was a defining year for GCT as we achieved key milestones toward commercialization and full-scale 5G deployment," said John Schlaefer, Chief Executive Officer of GCT. "During the fourth quarter, we shipped more than 1,900 5G chipsets for commercial use, marking a key step toward a broader volume production capability and increased 5G revenue contribution in 2026. Building on this momentum, we are continuing to work closely with customers to refine deployment schedules and align production with their launch plans. We also expanded our 5G customer ecosystem and advanced lead programs through evaluation, certification, and integration phases, further building the foundation for production ramps and a stronger revenue trajectory. Public confirmation from our first network operator, Gogo, regarding service activation of our chip marked an important milestone and represents the first step in what we expect to be a broader set of operators launching devices powered by GCT's 5G platform. Despite the transitional nature impacting our 2025 financial performance, we believe the groundwork laid over the past year positions us well for a pivotal shift in 2026. Our focus is on scaling operations to support commercialization, supply chain readiness, and internal execution to meet rising 5G demand. We are working toward driving meaningful 5G revenue contribution in the back half of 2026 as 5G deployments accelerate and production volumes ramp."

GCT Semiconductor Holding and Skylo Technologies, a global Non-Terrestrial Network provider, announced a partnership to advance next-generation satellite connectivity. As part of this collaboration, the companies will jointly pursue chip and module certification to enable a new class of multi-use devices. These devices will allow customers to have ubiquitous connectivity by connecting to Skylo's network when terrestrial connectivity is out of reach.

GCT Semiconductor Holding announced the first commercial shipments of its 5G chipset to its lead customers. The shipments follow successful qualification and adoption. "The commercial launch of our 5G chipset marks a pivotal step forward for GCT and represents an important milestone in our ability to generate revenues from our 5G products," said John Schlaefer, CEO of GCT Semiconductor.
