GCT Q2 2026 earnings: 5G shipments rise while gross margin turns negative

GCT Semiconductor (NYSE: GCTS) reported Q2 2026 net revenue of $971,000, down 17.9% from $1.18 million a year earlier, while GAAP diluted loss per share narrowed to $0.25 from $0.26. More than 5,100 5G chipsets shipped during the quarter, approximately 71% more than in Q1, but low product revenue left gross margin negative. Net loss widened to $20.4 million largely because of a $12.3 million non-cash warrant liability remeasurement loss.

Core financial results

Service revenue accounted for most of the top-line decline, falling to $569,000 from $774,000. Product revenue was nearly flat at $402,000, but product cost of revenue increased to $1.04 million, contributing to a consolidated gross loss of $226,000.

Operating expenses declined 9.8%, allowing the operating loss to narrow modestly. The much larger GAAP net loss was primarily attributable to the warrant liability adjustment rather than a comparable deterioration in operating performance.

The per-share loss narrowed even though the net loss increased because weighted-average common shares rose to 82.6 million from 51.7 million.

Business and 5G program performance

GCT shipped more than 5,100 5G chipsets in Q2, an approximately 71% sequential increase. Development, integration, certification and sales work continued across three target markets: terrestrial broadband, satellite and non-terrestrial connectivity, and IoT and specialized networks.

In terrestrial broadband, GCT advanced fixed wireless access and customer premises equipment programs alongside carrier certification work. Satellite activities included direct-to-device and hybrid satellite-cellular programs, while specialized applications included wearables, UAV communications, positioning and navigation, and aviation connectivity.

The company did not provide revenue by these end markets. It also said industry consolidation, customer restructuring and changing deployment schedules delayed some launches, meaning program activity and chipset shipments have not yet translated into a broad commercial revenue ramp.

5G shipment growth has not yet produced sufficient revenue scale

The central issue in the quarter was the gap between higher 5G shipment activity and weak reported financial results. Although the shipment comparison is sequential and the revenue comparison is year over year, current product revenue of only $402,000 remained too low to absorb production overhead.

Product gross loss was approximately $639,000, compared with a loss of approximately $174,000 a year earlier. Service operations remained profitable at the gross level, but lower service revenue was not enough to offset the deterioration in product economics. Management expects gross margin to improve as 5G product sales ramp, making the timing and scale of customer commercialization the main operational variable to monitor.

Profitability and balance sheet

The operating cost base was relatively stable after reductions in research and development and general and administrative expenses. Adjusted EBITDA loss improved slightly to $6.6 million, and GCT introduced this non-GAAP measure during the quarter to separate underlying operations from items such as warrant remeasurement, foreign exchange movements and stock-based compensation.

The $12.3 million warrant liability loss was non-cash and reflected increases in GCT’s common stock price and publicly traded warrant price during the quarter. It was the main reason the GAAP net loss widened much more sharply than the operating loss.

GCT ended June with $30.2 million in cash and cash equivalents, up from $590,000 at December 31, 2025. Current assets totaled $46.7 million versus current liabilities of $56.7 million, a gap of approximately $10.1 million. The balance sheet also included $39.1 million of current borrowings, $11.0 million of long-term borrowings and a $52.0 million stockholders’ deficit.

The company maintained a $200 million universal shelf registration and increased the maximum size of its at-the-market agreement from $75 million to $120 million. This expands access to potential financing but could dilute existing shareholders if additional shares are issued.

Guidance

GCT reaffirmed its directional shipment outlook rather than providing a specific revenue or earnings target. The expected second-half increase depends on customer programs continuing to move toward commercialization.

Management perspective

CEO John Schlaefer said customer engagement and the opportunity pipeline remained strong despite restructuring, industry consolidation and shifting launch schedules. Management’s focus is on moving programs from development and certification into commercial deployment across broadband, satellite and specialized connectivity markets.

CFO Edmond Cheng said first-half 2026 revenue slightly exceeded revenue for all of 2025. He also said GCT had secured the production capacity it expects to need for the remainder of 2026 and through Q1 2027.

Risks investors should monitor

• Commercialization delays: Customer restructuring and shifting deployment schedules have already changed the timing of some launches, potentially delaying revenue recognition.
• Negative product economics: Product revenue is not yet sufficient to absorb production overhead, leaving gross margin negative despite higher sequential chipset shipments.
• Liquidity and dilution: Current liabilities exceeded current assets at quarter-end, while the expanded $120 million ATM agreement creates potential dilution if used for financing.
• GAAP earnings volatility: Changes in the fair value of warrant and other financial liabilities can cause substantial non-cash swings in reported net income or loss.

Summary

GCT made measurable progress in 5G chipset shipments and customer programs during Q2 2026, but that activity had not yet produced enough revenue to support positive gross margin. Lower operating expenses kept the underlying operating loss relatively stable, while a non-cash warrant adjustment drove the wider GAAP net loss. The next key test is whether delayed customer programs enter commercial production quickly enough for second-half shipments to exceed first-half levels and improve product cost absorption.
