GCT Semiconductor Holding, Inc. Provides Business Update and Reports Third Quarter 2026 Financial Results
SAN JOSE, Calif.--( BUSINESS WIRE)--GCT Semiconductor Holding, Inc. (“GCT” or the “Company”) (NYSE: GCTS), a leading designer and supplier of 5G semiconductors powering the AI data pipeline with wireless connectivity, today provided an update on business developments and reported financial results for the third quarter ended September 30, 2026.
“We continued to make progress across our 5G customer programs in the third quarter, advancing integration and certification work with existing customers while expanding the range of applications our 5G chipsets can serve,” said John Schlaefer, CEO of GCT.
Expanding 5G Applications and Advancing Customer Programs
“We continued to make progress across our 5G customer programs in the third quarter, advancing integration and certification work with existing customers while expanding the range of applications our 5G chipsets can serve,” said John Schlaefer, Chief Executive Officer of GCT. “As a result, our 5G chipsets will be deployed beyond broadband and satellite connectivity into an even broader addressable market. That included adding a new customer in terrestrial services providing GNSS replacement with precise Z-axis positioning, which accounted for the majority of our 5G shipments in the quarter as it began proof-of-concept testing. With our existing customers, our programs continue to progress even as some are taking longer than planned to reach production and deployment. While the pace of our 5G chipset ramp is being driven primarily by customer integration schedules, not the capabilities of our 5G chipset, we are working closely alongside our customers to bring those programs to launch. We have secured our wafer capacity that we believe is sufficient to support our expected demand through the first half of 2027, positioning us to scale shipments as those launches occur.”
Third Quarter 2026 Financial Results
Results compare the 2026 fiscal third quarter ended September 30, 2026, to the 2025 fiscal third quarter ended September 30, 2025.
“Our third quarter results show continued year-over-year growth, though shipment volumes in the quarter reflected the extended timing of customer deployments rather than the full potential of our 5G programs,” said Edmond Cheng, Chief Financial Officer of GCT. “Revenue increased approximately 149% compared to the third quarter of 2025, driven by sustained level of product sales including 5G as customers advanced their programs toward launch. At the same time, we have continued to reduce our operating costs, which, together with our current cash position, keeps us well prepared as customer deployments move forward. We have reduced our “Net Cash Used in Operating Activities” from $16.6M in Q2 2026 to $8.5M in Q3 2026. Looking ahead to the remainder of 2026, our priorities remain the same: maintaining a disciplined cost structure and aligning our production investments with customer demand, so that we are ready to support 5G chipset volume as shipments ramp more significantly.”
Liquidity
The Company’s existing sources of liquidity as of September 30, 2026, include cash and cash equivalents of $17.2 million, net accounts receivable of $0.5 million, and inventory of $3.3 million. GCT currently has an effective universal shelf registration statement on Form S-3 that allows the Company to raise up to $200.0 million through the issuance of securities, including $120.0 million for an at-the-market (“ATM”) agreement. During the quarter ended September 30, 2026, GCT extended the maturities of $26.5 million of loans by one year.
5G Outlook
As customers take longer than originally expected to implement GCT’s 5G chipsets into their products and convert development programs into purchase orders, the Company now expects the ramp in 5G shipments to extend into the first half of 2027. Importantly, GCT has not lost any customers because of these extended timelines, its customer programs remain in active development, and the Company continued to expand its customer base in the third quarter.

Note Regarding Use of Non-GAAP Financial Measures
To supplement our financial statements presented in accordance with accounting principles generally accepted in the United States (“GAAP”), this earnings release and the accompanying tables and the related earnings conference call contain certain non-GAAP financial measures, including earnings or losses before interest, taxes, depreciation and amortization (“EBITDA”) and Adjusted EBITDA. We believe these financial measures provide useful information to investors with which to analyze our operating trends and performance.
In computing EBITDA, we start with net loss and exclude interest expense, interest income, income taxes and depreciation and amortization expenses. In computing Adjusted EBITDA, we start with EBITDA and exclude the following: stock-based compensation, gain/loss on foreign currency transactions, net, change in fair value of common stock forward liability, change in fair value of warrant liabilities and change in fair value of convertible promissory notes.
Management uses EBITDA and Adjusted EBITDA for business planning purposes, including managing our business against internally projected results of operations and measuring our performance. Management believes that these non-GAAP measures provide useful supplemental information to investors regarding our ongoing operations by eliminating certain items that are not directly related to ongoing operations or impact the generation of current or future revenues, such as non-cash expenses. Additionally, because of varying available valuation methodologies and subjective assumptions that can impact a company’s non-cash operating expenses, we believe that providing non-GAAP financial measures that primarily exclude non-cash expense allows for more meaningful comparisons between our core business operating results and those of other companies, as well as providing us with an important tool for financial and operational decision making and for evaluating our own core business operating results over different periods of time. Management considers certain of these adjustments, such as changes in the fair value of our common stock forward liability, warrant liabilities and convertible promissory notes, and foreign currency gains and losses, to be unpredictable and dependent on a considerable number of factors that are outside of our control and are not necessarily reflective of operational performance during a period.
These non-GAAP results should not be considered an alternative to, or a substitute for, GAAP financial information, and may differ from similarly titled non-GAAP measures used by other companies. GCT has included these non-GAAP measures to give investors an opportunity to see the Company’s financial results as viewed by management. A reconciliation of the comparable GAAP financial measures to the non-GAAP financial measures is provided at the end of the Company’s unaudited consolidated financial statements presented below.
Cautionary Statement Regarding Forward-Looking Statements
