Company Overview

GCT Semiconductor Holding, Inc. (“GCT” or the “Company”) was founded in Silicon Valley, California in 1998 as GCT Semiconductor, Inc., and the Company is a fabless semiconductor company that specializes in the design, manufacturing and sale of communication semiconductors, including high-speed wireless communication technologies such as 5G/4.75G/4.5G/4G transceivers (“RF”) and modems, which are essential for a wide variety of industrial, B2B and consumer applications. We have successfully developed and supplied communication semiconductor chipsets and modules to leading wireless operators worldwide, as well as to original design manufacturers (“ODMs”) and original equipment manufacturers (“OEMs”) for portable wireless routers (e.g., Mobile Router/MiFi), indoor and outdoor fixed wireless routers (e.g., Customer Premises Equipment (“CPE”)), industrial M2M applications and smartphones.

We oversee sales, marketing and accounting operations from our headquarters in San Jose, California. The Company conducts product design, development and customer support through our fully owned subsidiaries, GCT Research Inc. (“GCT R”) and MTH, Inc. (“MTH”), both of which are located in South Korea. GCT R serves as our research and development center. In addition, we utilize separate sales offices for local technical support and sales in Taiwan, China, and Japan.

Our current product portfolio includes RF and modem chipsets based on 4th generation (“4G”) Long Term Evolution (“LTE”) technology, offering a variety of chipsets differentiated by speed and functionality. These include 4G LTE, 4.5G LTE Advanced (twice the speed of LTE) and 4.75G LTE Advanced-Pro (four times the speed of LTE) chipsets. We also develop and sell cellular Internet of Things (“IoT”) chipsets for low-speed mobile networks such as eMTC/NB-IOT/Sigfox, and other network protocols.

Notably, we leverage our proprietary knowledge and patents, which have been proven in 4G products to employ up to eight receiving antennas in sub-6GHz wireless bands, extending the receive-coverage and throughput by more than two times compared to the case of using two or four receiving antennas. We also employ up to four transmitting antennas, enhancing the transmission coverage and throughput compared to using only one or two transmission antennas. Several top tier wireless operators have engaged the Company as a result of this unique technology. Building on this
