GCT Semiconductor Holding, Inc. began commercial shipments of its 5G chipset on January 6 2026, marking the first time the company has generated revenue from the product line. The launch follows the completion of the company’s 2025 Year of 5G program and the announcement by GoGo that it will deploy a 5G air‑to‑ground network, underscoring market demand for GCT’s technology.
The commercial rollout comes after a challenging fiscal year. In Q3 2025, GCT reported net revenues of $0.4 million, a steep decline from $2.6 million in the same quarter a year earlier. The drop reflects weaker demand in legacy markets and the company’s ongoing investment in new 5G capabilities, which has pushed gross margins into negative territory and accelerated cash burn. The new shipments are expected to reverse the revenue decline by opening a steady revenue stream in niche 5G verticals.
To support the commercialization effort, GCT secured a convertible promissory note purchase agreement with Indigo Capital LP that allows the company to raise up to $20 million, with an initial $1 million advance. The financing provides working capital to scale production, expand sales coverage, and fund ongoing R&D, while the convertible structure aligns investor interests with the company’s long‑term growth prospects.
GCT’s strategic focus on non‑terrestrial networks, aviation, and industrial IoT differentiates it from larger competitors such as Qualcomm and MediaTek. The partnership with GoGo, which is deploying a 5G air‑to‑ground network, serves as a high‑profile validation of the chipset’s performance and opens a significant customer base in the aviation sector.
CEO John Schlaefer said the commercial launch is a pivotal step for GCT and that customer response has been “extremely encouraging.” He added that the company is “seeing strong interest across multiple 5G applications” and that the launch marks the beginning of a significant growth cycle for the business.
The company remains focused on scaling its niche 5G portfolio while managing cash burn. Management’s emphasis on disciplined cost control, strategic financing, and targeted partnerships signals confidence in turning the current revenue shortfall into a sustainable growth trajectory.
