(the &ldquo;Shares&rdquo;) of our common stock, par value $0.0001 per share (the &ldquo;Common Stock&rdquo;) and Common Stock Purchase
Warrants (the &ldquo;Warrants&rdquo;, together with the Shares, the &ldquo;Securities) to purchase up to 10,509,555 shares of Common Stock
to certain institutional investors pursuant to this prospectus supplement and the accompanying prospectus (the &ldquo;Offering&rdquo;).
Each Share of Common Stock we sell in the Offering will be accompanied by a Warrant to purchase up to one and a half shares of Common
Stock. Each Warrant will have an exercise price of $1.71 per share, will be exercisable beginning six months from the issuance date and
will expire five years from the initial exercise date. Each Share of Common Stock and accompanying Warrant will be sold at a combined
purchase price of $1.57. The Shares of Common Stock and Warrants are immediately separable and will be issued separately but can only
be purchased together in this Offering. This prospectus supplement also relates to the offering of the Shares of Common Stock issuable
upon exercise of the&nbsp;Warrants sold in this Offering.</P>

trading market for the Warrants, and we do not expect a market to develop. We do not intend to apply for listing of the Warrants on any
securities exchange or other nationally recognized trading system. Without an active trading market, the liquidity of the Warrants will
be limited.</P>

(&ldquo;GCT&rdquo;) 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 (&ldquo;RF&rdquo;) 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 (&ldquo;ODMs&rdquo;) and original equipment manufacturers (&ldquo;OEMs&rdquo;) for portable wireless
routers (e.g., Mobile Router/MiFi), indoor and outdoor fixed wireless routers (e.g., CPE), industrial machine-to-machine (&ldquo;M2M&rdquo;)
applications and smartphones.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 5pt; text-align: justify; text-indent: 0.25in">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,&nbsp;Inc. (&ldquo;GCT R&rdquo;) and MTH,&nbsp;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.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 5pt; text-align: justify; text-indent: 0.25in">Our current product portfolio
includes RF and modem chipsets based on 4th generation (&ldquo;4G&rdquo;), known as Long Term Evolution (&ldquo;LTE&rdquo;), 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.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 5pt; text-align: justify; text-indent: 0.25in">We are a &ldquo;smaller reporting
company&rdquo; meaning that the market value of our Common Stock held by non-affiliates is less than $250.0 million measured on the last
business day of our second fiscal quarter or our annual revenue is less than $100.0 million during the most recent completed fiscal year
and the market value of our Common Stock held by non-affiliates is less than $700.0 million measured on the last business day of our second
fiscal quarter. Accordingly, we may provide less public disclosure than larger public companies, including the inclusion of only two years
of audited financial statements and only two years of management&rsquo;s discussion and analysis of financial condition and results of
operations disclosure. As a result, the information that we provide to our stockholders may be different than you might receive from other
public reporting companies in which you hold equity interests.</P>

Dilution per share to new investors is determined by subtracting as adjusted net tangible book value per share after this Offering from
the offering price per share paid by new investors. The following table illustrates this dilution on a per share basis:</P>

10,509,555 shares of our Common Stock.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.25in"><I>Form</I>.&nbsp; The Warrants
will be issued as individual warrant agreements to the investors. You should review a copy of the form of Warrant, which will be filed
as an exhibit to a Current Report on Form&nbsp;8-K by us with the SEC, in connection with this Offering within the time period required
by such form, for a complete description of the terms and conditions applicable to the Warrants.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 20pt"><I>Exercisability</I>.&nbsp;The
Warrants will become exercisable six months from the issuance date, and will expire five&nbsp;years from the initial exercise date. The
Warrants will be exercisable, at the option of each holder, in whole or in part by delivering to us a duly executed exercise notice and,
at any time a registration statement registering the issuance of the shares of Common Stock underlying the Warrants under the Securities
Act of 1933, as amended (the &ldquo;Securities Act&rdquo;), is effective and available for the issuance of such shares, or an exemption
from registration under the Securities Act is available for the issuance of such shares, by payment in full in immediately available funds
for the number of shares of Common Stock purchased upon such exercise. If a registration statement registering the issuance of the shares
of Common Stock underlying the Warrants under the Securities Act is not then effective or available, the holder may only exercise the
Warrant through a cashless exercise, in which case the holder would receive upon such exercise the net number of shares of Common Stock
determined according to the formula set forth in the Warrant. No fractional shares of Common Stock will be issued in connection with the
exercise of a Warrant. In lieu of fractional shares, we will pay the holder an amount in cash equal to the fractional amount multiplied
by the exercise price or round up to the next whole share, at our option.</P>

A holder will not have the right to exercise any portion of the Warrant if the holder (together with its affiliates) would beneficially
own in excess of 4.99% (or 9.99% at the election of a holder prior to the date of issuance) of the number of shares of our Common Stock
outstanding immediately after giving effect to the exercise, as such&nbsp;percentage ownership is determined in accordance with the terms
of the Warrants. However, any holder may increase or decrease such&nbsp;percentage to any other&nbsp;percentage not in excess of 9.99%
upon at least 61&nbsp;days&rsquo; prior notice from the holder to us.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 20pt"><I>Exercise Price; Adjustment</I>.&nbsp;The
initial exercise price per share of Common Stock issuable upon exercise of the Warrants is $1.71 per share of Common Stock. The exercise
price is subject to appropriate adjustment in the event of certain stock dividends and distributions, stock splits, stock combinations,
reclassifications or similar events affecting our Common Stock and also upon any distributions of assets, including cash, stock or other
property to our stockholders.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify; text-indent: 0.5in">We are a &ldquo;smaller
reporting company&rdquo; meaning that the market value of our Common Stock held by non-affiliates is less than $250.0 million measured
on the last business day of our second fiscal quarter or our annual revenue is less than $100.0 million during the most recent completed
fiscal year and the market value of our Common Stock held by non-affiliates is less than $700.0 million measured on the last business
day of our second fiscal quarter. Accordingly, we may provide less public disclosure than larger public companies, including the inclusion
of only two years of audited financial statements and only two years of management&rsquo;s discussion and analysis of financial condition
and results of operations disclosure. As a result, the information that we provide to our stockholders may be different than you might
receive from other public reporting companies in which you hold equity interests.</P>

and transfer system, the number of shares or principal amount of securities of the individual beneficial interests represented by these
global securities to the respective accounts of persons who have accounts with the depository. Ownership of beneficial interests in the
global securities will be shown on, and the transfer of this ownership will be effected only through, records maintained by the depository
or its nominee with respect to interests of participants and the records of participants with respect to interests of persons other than
participants. These accounts initially will be designated by or on behalf of the underwriters, initial purchasers or agents, or by us
if we offer and sell the debt securities directly, and ownership of beneficial interests in the global securities will be limited to participants
or persons who hold interests through participants. Qualified institutional buyers may hold their interests in the global securities directly
through the depository if they are participants in this system, or indirectly through organizations which are participants in this system.
The laws of some states of the U.S. may require that some purchasers of securities take physical delivery of the debt securities in definitive
registered form. These limits and the laws may impair your ability to own, transfer or pledge interests in the global securities.</P>

the depository, or its nominee, is the registered owner or holder of the debt securities, the depository or its nominee, as the case may
be, will be considered the sole owner or holder of the debt securities represented by the global securities for all purposes. No beneficial
owner of an interest in the global securities will be able to transfer that interest except in accordance with the depository&rsquo;s
procedures.</P>
