GCT Semiconductor Holding Inc. reported its fourth‑quarter and full‑year 2025 results on March 25, 2026. Revenue for the quarter fell to $0.76 million, a 57.5 % decline from the $1.8 million earned in Q4 2024, while the company posted a net loss of $43.4 million for the year, up from $12.4 million in 2024. Earnings per share for the quarter were –$0.16, beating the consensus estimate of –$0.21.
The revenue drop reflects a sharp decline in product volumes as the company transitions to 5G chipsets, while general and administrative expenses remained high. Despite the revenue miss, the quarter saw a 76 % sequential increase in revenue, driven by the shipment of more than 1,900 5G chipsets for commercial use.
The EPS beat of $0.05, or 23.8 %, was driven by tighter cost management and a higher mix of 5G shipments, which offset the lower overall revenue. The company’s gross margin for the quarter was negative, a reversal from the 32 % margin reported in Q4 2024, underscoring the impact of low volumes on profitability.
For the full year, revenue totaled $2.9 million, down 68 % from $9.1 million in 2024, and the net loss widened to $43.4 million. The negative gross margin for the year, compared with a 56 % margin in 2024, highlights the cost intensity of the company’s current production scale.
Management outlined a forward‑looking outlook that emphasizes sequential revenue growth and expanding 5G chipset shipments throughout 2026. "We are working toward driving meaningful 5G revenue contribution in the back half of 2026 as 5G deployments accelerate and production volumes ramp," said Chief Executive Officer John Schlaefer. "While our 2025 financial results reflect deliberate investments required to bring our 5G chipset to commercial readiness, these investments are critical for generating sustainable long‑term growth," added Chief Financial Officer Edmond Cheng.
The company faces headwinds from negative gross margins, a widening net loss, and elevated general and administrative costs. However, tailwinds include the commencement of commercial 5G chipset shipments, a licensing agreement with a satellite communications provider, a partnership with Skylo, and the successful launch of Gogo’s broadband service using GCT’s 5G chipset, all of which are expected to support revenue growth in the second half of 2026.
Chief Executive Officer John Schlaefer said, "We believe Q3 of 2025 marked the bottom of our revenue cycle caused by the major product transition to 5G, and as we enter 2026, we are encouraged by continued progress across our 5G programs, including certification processes underway with at least two network operators advancing toward service launch."
