GCT Semiconductor outlines 5G mass production and volume shipments for Q4 2025 while expanding customer ecosystem

Earnings Call Insights: GCT Semiconductor Holding, Inc. (GCTS) Q2 2025

MANAGEMENT VIEW

* CEO John Brian Schlaefer announced progress under the "2025 GCT year of 5G" program, emphasizing the delivery of initial 5G chipset samples to lead customers, including Orbic North America and Airspan Networks, with successful testing underway. Schlaefer stated, "this marks a major leap forward and allows us to begin the transition of our focus towards mass production and the imminent commercial launch of our 5G chipset."
* Schlaefer shared that additional samples are expected to be delivered in the coming weeks, with production of the finalized initial 5G chipset to commence in the third quarter and volume production and shipments targeted for the fourth quarter of 2025.
* The company announced a collaboration with Iridium Communications to integrate NTN Direct satellite service into the GDM7243SL chipset and a partnership with G+D for embedded eSIM solutions for IoT applications, broadening its reach into the nonterrestrial network space and IoT markets.
* CFO Fong Ting Cheng commented, "While our financial results reflect the continued shift from 4G towards 5G, they are consistent with the transitional phase we are currently in. We anticipate a stronger end of the year as 5G chipset sales to commence soon. As I have mentioned before, the average selling price of this 5G chipset is expected to be roughly 4x that of our traditional 4G products."

OUTLOOK

* Schlaefer emphasized a focus on scaling the 5G platform, ensuring supply chain readiness, and executing on expected demand as customers launch their next-generation products.
* Management anticipates 5G chipset sales to begin in the second half of 2025, with a particular impact expected in Q4 as volume production and shipments start.
* The company expects operational efficiencies to improve gross margin as revenue increases when 5G product sales scale.

FINANCIAL RESULTS

* Net revenues were $1.2 million for the three months ended June 30, 2025, a decrease of $0.3 million or 19% from $1.5 million in the same period last year. The decrease was primarily due to a $0.7 million drop in service revenue, partially offset by a $0.4 million increase in product sales driven by 4G chipsets.
* Cost of net revenues increased by $0.3 million or 47% to $0.8 million, attributed to increased product sales activity. Gross margin dropped to 32% from 63% a year ago, with service business margin at 71.3% and product sales margin at negative 42.6%. Cheng noted that gross margin for product sales is "still distorted by the lower product revenue, which makes it less indicative of the underlying profitability of our products when we transition to scale our new 5G product sales."
* Research and development expenses decreased by $0.7 million or 16% to $3.5 million, primarily due to lower professional services related to 5G chip design. Sales and marketing expenses remained steady at $1 million. General and administrative expenses rose by $0.6 million or 20% to $3.4 million, mainly due to an increase in expected credit loss estimates.
* The company ended the quarter with $1.3 million in cash and cash equivalents, $3.8 million in net accounts receivable, and $3 million in net inventory. GCT received $11 million in gross proceeds from a registered direct offering during the quarter.

Q&A

* Operator indicated there were no questions in the queue for this quarter’s call, and the meeting concluded without a Q&A session.

SENTIMENT ANALYSIS

* Analysts did not pose questions this quarter, resulting in no discernible analyst sentiment from the call.
* Management maintained an optimistic tone in prepared remarks, frequently referencing milestones and imminent transitions, such as Schlaefer’s statement, "The delivery of our initial 5G chipsets to lead customers, the validation successes we're seeing and now the preparation for volume shipments all point to one thing. GCT is on the verge of a meaningful inflection."
* Compared to the previous quarter, management’s confidence remained strong, but the lack of analyst interaction removed immediate external scrutiny or skepticism.

QUARTER-OVER-QUARTER COMPARISON

* The current quarter was marked by the official delivery and successful testing of 5G chipsets, with a clear timeline for mass production and commercial launch, a step forward from last quarter’s focus on internal evaluation and sampling plans.
* Revenue continued to reflect the transition away from 4G, and the gross margin remained pressured by low product volumes, but management reiterated expectations of improvement with 5G sales.
* Analyst focus in the prior quarter highlighted operational ramp and partnership leverage; this quarter, with no analyst questions, there was no external probing of execution risks or financial forecasts.
* Strategic priorities evolved from partnership and sampling announcements to preparing for volume production, expanded ecosystem collaborations, and infrastructure readiness for 5G.
* Management’s tone remained highly confident, with forward-looking statements emphasizing transformation and upcoming inflection points.

RISKS AND CONCERNS

* Cheng stated that current gross margins, especially for product sales, are negatively affected by low product revenue and not indicative of future profitability, signaling ongoing risk until 5G revenues materialize.
* The company continues to operate with a modest cash balance, though recent financing has provided flexibility.
* Management acknowledged the transitional revenue decline, with expectations for improvement tied directly to the commercial launch and scaling of 5G chipsets.

FINAL TAKEAWAY

GCT Semiconductor highlighted a pivotal transition quarter, delivering and validating initial 5G chipsets with key customers and outlining a clear path to mass production and commercial shipments starting in Q4 2025. Management underscored the expected transformational impact of 5G revenue on financial results and operational efficiency, supported by new ecosystem partnerships and strengthened funding. The company remains focused on executing its 5G roadmap, preparing the supply chain, and capturing demand as customers bring next-generation products to market in the second half of the year.
