GCT Semiconductor (GCTS) investor relations material

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.

• Net loss widened to $9.9 million from $7.0 million year-over-year, primarily due to higher interest expense and fair value losses on warrants and convertible notes.

• Expanded a key licensing and reference platform agreement with a major satellite communication provider, broadening 5G and 4G chipset integration and positioning for multi-phase adoption.

• The company remains dependent on external financing and faces substantial doubt about its ability to continue as a going concern beyond the next 12 months.
