GCT Semiconductor Holding, Inc. Q1 FY2026 earnings call

• 5G Commercialization Progress
  • The quarter marked meaningful progress in the transition from 5G chipset development to commercialization, with growing shipment volumes and expanding customer engagement.
  • 3,000 5G chipsets were delivered, a 58% sequential increase over Q4 2025, reflecting customer movement through final testing to initial deployments.
  • The company supports growing customer programs across three 5G verticals: FWA, IoT, and NTN, with deeper platform-level collaboration beyond traditional licensing.
  • A new reference platform agreement was signed with a major global satellite communication provider to accelerate converged satellite-terrestrial 5G deployment; initial 5G shipments to this partner remain on track for H2 2026.
• Financial Performance
  • Net revenue grew 288% year-over-year to $1.9 million, from $0.5 million in Q1 2025.
  • Gross margin expanded significantly to 49% in Q1 2026, up from 18% in Q1 2025, driven by a favorable revenue mix of higher-margin service revenue and an increased share of 5G product sales.
  • R&D expenses decreased 23% year-over-year to $3.2 million, due to lower one-time IP and design completion costs from the 2025 5G chipset development project.
  • Sales and marketing, and general and administrative expenses remained relatively flat year-over-year at $1.2 million and $2.7 million respectively.
• Liquidity and Capital Allocation
  • The company ended the quarter with $7.2 million in cash and cash equivalents, $2.4 million in accounts receivable, and $1.6 million in net inventory.
  • The company maintains full access to a $75 million at-the-market equity program and ample remaining capacity on its $125 million effective S-3 shelf registration, providing sufficient financial flexibility for commercial scale-up.

The company has not yet formally split reporting into the planned FWA, IoT, and NTN vertical product segments. For Q1 2026, total net revenue was $1.9 million, with total product revenue contributing $0.9 million (47.4% of total net revenue) and service/licensing revenue contributing $1.0 million (52.6% of total net revenue). Product revenue growth was led by increased 4G and 5G chipset sales, while service revenue growth was driven by 5G operations (partially offset by declining LTE service revenue as the company shifts its portfolio to 5G). 5G chipset shipments for the quarter totaled 3,000 units, representing a 58% sequential increase from Q4 2025.

• Management expects 5G chipset shipments to continue sequential growth throughout 2026 as commercialization scales, with upward momentum on track following Q1 gains.
• As chipset volume scales in H2 2026, product revenue will become the dominant share of total revenue, replacing the current majority contribution from service revenue.
• Gross margins are expected to normalize to the high 30% to low 40% range as product revenue becomes the primary revenue contributor, down from the 49% Q1 2026 margin driven by high-margin one-time service revenue recognition.
• Quarterly operating expenses are expected to rise to a run rate of ~$8 million per quarter starting in Q3 2026, as R&D spending increases to support the company's product roadmap.
• Service revenue in future quarters is expected to be lower than the Q1 2026 level of $1 million, as the Q1 service revenue included a one-time licensing milestone recognition; future service revenue will be tied to irregular contract milestones that are difficult to predict in advance.
• Product revenue growth is expected to follow a bursty pattern in the early ramp stage, with customer contribution varying quarter-to-quarter as volumes remain low, and will diversify across a broader customer base over time.

• 5G commercialization is in early stages, with current shipment volumes still modest relative to long-term market opportunity.
• Timing and pace of customer 5G deployments can vary as customers finalize their rollout plans, creating uncertainty around near-term revenue growth.
• Future service revenue from contract milestones is unpredictable in terms of timing and magnitude, creating potential quarterly revenue volatility.

Q: The $1.9 million Q1 2026 revenue has a large service and licensing contribution alongside chip sales. How will this revenue mix change as chip volumes scale in H2 2026? / A: Service revenue is currently a large share of quarterly revenue because it is recognized as contract milestones are completed. As 5G chipset sales grow, product revenue will far outpace service revenue, becoming the substantial majority of total quarterly revenue going forward. GCT's core growth business is chipset product sales, not services.\n\nQ: Q1 2026 gross margin of ~49% is far above prior quarters. Is this structural or one-time, and what should we expect for margins in H2 2026? / A: The elevated Q1 margin is driven by the large share of high-margin service revenue this quarter, and it is not the expected long-term margin when product sales dominate. Management still expects product-focused gross margins to stabilize in the high 30% to low 40% range as product volume scales.\n\nQ: Does Q1 2026 service revenue include one-time amounts, and should we expect $1 million+ quarterly service revenue going forward? / A: Q1 2026 included a one-time licensing revenue recognition. Future service revenue will be recognized as contract milestones are hit, but it will not be as high as Q1 2026, and milestone timing is hard to predict in advance.\n\nQ: How many product customers did GCT have in Q1 2026, and how will the product ramp progress across customers? / A: GCT had between 5 and 7 product customers in Q1, up from fewer in the prior quarter, with some orders coming through distribution. Early-stage low volume product revenue will be bursty, with varying customer contribution quarter-to-quarter, but will diversify to a broad, steady distribution of customers over time.
