GCT Semiconductor (GCTS) Q1 2026 earnings summary

Executive summary

• Q1 2026 revenue rose 287% year-over-year to $1.9 million, driven by a 58% sequential increase in 5G chipset shipments and new service and LTE product sales, reflecting early commercial traction and expanding customer engagements across FWA, IoT, and NTN.

• Gross margin improved to 49%–49.3% from 17.7%–18% year-over-year, reflecting a favorable revenue mix with higher-margin service and licensing revenue and increased 5G product sales.
