Business Summary

Company Overview

GCT Semiconductor Holding, Inc.
(“GCT”) was founded in Silicon Valley, California in 1998 and 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., CPE), industrial machine-to-machine (“M2M”)
applications and smartphones.

We oversee sales, marketing,
and accounting operations from our headquarters in San Jose, California. We conduct product design, development, and customer support
through our fully owned subsidiaries, GCT Research, Inc. (“GCT R”) and MTH, Inc., 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”), known as 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 IoT chipsets for low-speed
mobile networks such as eMTC/NB- IOT/Sigfox, and other network protocols.
