GCT Semiconductor 2025 Q3 Earnings Widened Net Loss Signals Transition Challenges

GCT Semiconductor (GCTS) reported Q3 2025 results marked by an 83.5% revenue decline and a 94.5% wider net loss compared to the prior year. The company missed revenue expectations by $0.79 million, with management highlighting initial 5G product revenue as a key milestone. CEO John Schlaefer outlined plans for Q4 2025 shipments and 2026 production scaling, while CFO Fong Cheng reiterated adjusted EBITDA breakeven by Q3 2026.

Revenue

Total revenue plummeted to $430,000 in Q3 2025, a sharp decline from $2.61 million in Q3 2024, driven by a $1.6 million drop in product sales and a $600,000 reduction in service revenue. The product segment contributed $148,000, while the service segment accounted for $282,000. This performance reflects a transitional phase as the company shifts focus to 5G commercialization.

Earnings/Net Income

Net losses expanded to $13.85 million in Q3 2025, a 94.5% increase from $7.12 million in Q3 2024, with GAAP EPS of -$0.25, worsening from -$0.16 per share. The losses reflect elevated production costs and inventory write-downs, underscoring the financial strain of transitioning to 5G volume sales.

Post-Earnings Price Action Review

The strategy of buying GCTS following a revenue beat and holding for 30 days leverages positive momentum from the company’s first 5G product revenue. Despite a modest beat, this milestone signals progress in commercialization, supported by $10.7 million in financing to scale production. The 30-day window captures short-term gains from market optimism, while the company’s leadership in 5G partnerships and production readiness positions it for 2026 growth. Mixed analyst ratings persist, but recent developments may shift sentiment. Investors must weigh risks from volatile market reactions and operational challenges.
