Item 1.  Business

AXT, Inc. (“AXT”, “the Company”, “we,” “us,” and “our” refer to AXT, Inc. and its consolidated subsidiaries) is

a materials science company that develops and produces high-performance compound and single element semiconductor
substrates, also known as wafers. Two of our consolidated subsidiaries produce and sell certain raw materials some of
which are used in our substrate manufacturing process and some of which are sold to other companies.

Our substrate wafers are used when a typical silicon substrate wafer cannot meet the performance requirements of

a semiconductor or optoelectronic device. The dominant substrates used in producing semiconductor chips and other
electronic circuits are made from silicon. However, certain chips may become too hot or perform their function too slowly
if silicon is used as the base material.  In addition, optoelectronic applications, such as LED lighting and chip-based lasers,
do not use silicon substrates because they require a wave form frequency that cannot be achieved using silicon. Alternative
or specialty materials are used to replace silicon as the preferred base in these situations. Our wafers provide such
alternative or specialty materials. We do not design or manufacture the chips. We add value by researching, developing and
producing the specialty material wafers. We have two product lines: specialty material substrates and raw materials integral
to these substrates. Our compound substrates combine indium with phosphorous (indium phosphide: InP) or gallium with
arsenic (gallium arsenide: GaAs). Our single element substrates are made from germanium (Ge).

InP is a high-performance semiconductor substrate used in broadband and fiber optic applications, 5G

infrastructure and data center connectivity. InP substrates are also used in biometric wearables and other health monitoring
applications. In recent years, InP demand has increased. Semi-insulating GaAs substrates are used to create various high-
speed microwave components, including power amplifier chips used in cell phones, satellite communications and broadcast
television applications. Semi-conducting GaAs substrates are used to create opto-electronic products, including high
brightness light emitting diodes (HBLEDs) that are often used to backlight wireless handsets and liquid crystal display
(LCD) TVs and also used for automotive panels, signage, display and lighting applications. A new application for semi-
conducting GaAs substrates is 3-D sensing chips using VCSELs (vertical cavity surface emitting lasers) as an array of
lasers on a single chip that can be used in cell phones and other devices. GaAs wafers could also be used for making micro-
LEDs. Ge substrates are used in applications such as solar cells for space and terrestrial photovoltaic applications.

Our supply chain strategy includes partial ownership of raw material companies. Two of these companies are
consolidated. One of these consolidated companies produces pyrolytic boron nitride (pBN) crucibles used in the high
temperature (typically in the range 500 C to 1,500 C) growth process of single crystal ingots, effusion rings when growing
OLED (Organic Light Emitting Diode) tools, epitaxial layer growth in MOCVD (Metal-Organic Chemical Vapor
Deposition) reactors and MBE (Molecular Beam Epitaxy) reactors. We use these pBN crucibles in our own ingot growth
processes and they are also sold in the open market to other companies. The second consolidated company converts raw
gallium to purified gallium. We use purified gallium in producing our GaAs substrates and it is also sold in the open market
to other companies for use in producing magnetic materials, high temperature thermometers, single crystal ingots,
including gallium arsenide, gallium nitride, gallium antimonite and gallium phosphide ingots, and other materials and
alloys. In addition to purified gallium, the second consolidated company also produces InP base material which we then
use to grow single crystal ingots. In prior years, a third company was consolidated, but, in the first quarter of 2019, we sold
a portion of our ownership to our investment partner and, as of March 11, 2019, we ceased to consolidate this company.
Our substrate product group generated 79%, 81% and 79% of our consolidated revenue and our raw materials product
group generated 21%, 19% and 21% for 2020, 2019 and 2018, respectively.

We manufacture all of our products in the People’s Republic of China (PRC or China), which generally has

favorable costs for facilities and labor compared with comparable facilities in the United States, Europe or Japan. Our
supply chain includes partial ownership of raw material companies in China (subsidiaries/joint ventures). We believe this
supply chain arrangement provides us with pricing advantages, reliable supply, market trend visibility and better sourcing
lead-times for key raw materials central to manufacturing our substrates. Our raw material companies produce materials,
including raw gallium (4N Ga), high purity gallium (6N and 7N Ga), starting material for InP, arsenic, germanium,
germanium dioxide, pyrolytic boron nitride (pBN) crucibles and boron oxide (B2O3). We have board representation in all
of these raw material companies. We consolidate the companies in which we have either a controlling financial interest, or
majority financial interest combined with the ability to exercise substantive control over the operations, or financial
decisions, of such companies. We use the equity method to account for companies in which we have smaller financial
interest and have the ability to exercise significant influence, but not control, over such companies. We purchase portions
of the materials produced by these companies for our own use and they sell the remainder of their production to third
parties.

The Beijing city government is moving its offices into the area where our original manufacturing facility is

currently located and is in the process of moving thousands of government employees into this area. The government has
constructed showcase tower buildings and overseen the establishment of new apartment complexes, retail stores and
restaurants. An amusement park is being constructed within a few miles of our facility. To create room and upgrade the
district, the city instructed virtually all existing manufacturing companies, including AXT, to relocate all or some of their
manufacturing lines. We were instructed to relocate our gallium arsenide manufacturing lines. For reasons of
manufacturing efficiency, we elected to also move our germanium manufacturing line. Our indium phosphide
manufacturing line, as well as various administrative and sales functions, will remain primarily at our original site in
Beijing.

Begun in 2017, the relocation of our gallium arsenide production lines is now largely completed.  We entered into 

volume production in 2020. To mitigate our risks and maintain our production schedule, we moved our gallium arsenide 
equipment in stages. By December 31, 2019, we had ceased all crystal growth for gallium arsenide in our original 
manufacturing facility in Beijing and transferred 100% of our ingot production to our new manufacturing facility in Kazuo, 
a city approximately 250 miles from Beijing. We transferred our wafer processing equipment for gallium arsenide to our 
new manufacturing facility in Dingxing, a city approximately 75 miles from Beijing. Some of our larger, more 
sophisticated customers qualified gallium arsenide wafers from the new sites in 2020.  A few customers are still in that 
process. Our new facilities enabled us to expand capacity and upgrade some of our equipment.  The new buildings are large 
enough that we can install additional equipment if market demand increases or if we gain market share.  We also acquired 
sufficient land to enable us to add facilities, if needed in the future. We believe our ability to add capacity gives us a 
competitive advantage. In addition, a new level of technological sophistication in our manufacturing capabilities will 
enable us to support the major trends that we believe are likely to drive demand for our products in the years ahead. 

Customer qualifications and expanding capacity as needed require us to continue to diligently address the many
details that arise at both of the new sites. A failure to properly accomplish this could result in disruption to our production
and have a material adverse impact on our revenue, our results of operations and our financial condition. If we fail to meet
the product qualification and volume requirements of a customer, we may lose sales to that customer. Our reputation may
also be damaged. Any loss of sales could have a material adverse effect on our revenue, our results of operations and our
financial condition.

On  November  16,  2020  we  announced  a  strategic  initiative  to  access  China’s  capital  markets  by  beginning  a
process to list shares of Tongmei in an initial public offering (the “IPO”) on the STAR Market, an exchange intended to
support innovative companies in China. We formed and founded Tongmei in 1998 and believe Tongmei has grown into a
company that will be an attractive offering on the STAR Market. To qualify for a STAR Market listing, the first major step
in  the  process  was  to  engage  private  equity  firms  in  China  (“Investors”)  to  invest  funds  in  Tongmei.  By  December  31,
2020,  investors  which  consists  of  10  private  equity  funds  had  engaged  with  Tongmei  for  a  total  investment  of
approximately $48.1 million. (The currency used in the investment transactions was the Chinese renminbi, which has been
converted  to  approximate  U.S.  dollars  for  this  report.)  The  remaining  investment  of  approximately  $1.5  million  of  new
capital was funded in early January. Under China regulations these investments must be formally approved by the

5

Table of Contents

appropriate government agency and are not deemed to be dilutive until such approval is granted. The government approved
the entire approximately $49 million investment on January 25, 2021. In exchange for an investment of approximately $49
million,  the  Investors  received  a  7.28%  noncontrolling  interest  in  Tongmei.  Pursuant  to  the  investment  agreements
(“Capital  Investment  Agreements”)  with  the  Investors,  each  Investor  has  the  right  to  require  AXT  to  redeem  any  or  all
Tongmei shares held by such Investor at the original purchase price paid by such Investor, without interest, in the event of a
material adverse change or if Tongmei does not achieve its IPO on or before December 31, 2022. This right is suspended
when Tongmei submits its formal application for IPO to the China Securities Regulatory Commission (“CSRC”).  Tongmei
currently plans to submit its formal application to the CSRC in the third quarter of 2021.  However, if on December 31,
2022  the  IPO  application  has  been  submitted  and  accepted  by  the  CSRC  or  the  stock  exchange  and  such  submission
remains under review, then the date when such investor is entitled to exercise such redemption right shall be deferred to a
date  when  such  submission  is  rejected  by  the  CSRC  or  stock  exchange,  or  the  date  when  Tongmei  withdraws  its  IPO
application. Tongmei would be required to sell a minimum of 10% of its equity in the IPO. The process of going public on
the  STAR  Market  includes  several  periods  of  review  and  is  therefore  a  lengthy  process.  Tongmei  does  not  expect  to
complete the IPO until mid-2022. The listing of Tongmei on China’s STAR Market will not change the status of AXT as a
U.S. public company.

An  additional  step  in  the  STAR  Market  IPO  process  involves  certain  entity  reorganizations  and  alignment  of
assets  under  Tongmei.  In  this  regard  our  two  consolidated  raw  material  companies,  Nanjing  JinMei  Gallium  Co.,  Ltd.
(“JinMei”) and Beijing BoYu Semiconductor Vessel Craftwork Technology Co., Ltd. (“BoYu”) and its subsidiaries were
assigned  to  Tongmei  in  December  2020.  This  will  increase  the  number  of  customers  and  employees  attributable  to
Tongmei as well as increase Tongmei’s consolidated revenue.

The following organization chart depicts the consolidated structure as of December 31, 2020;

In September 2018, the Trump Administration announced a list of thousands of categories of goods that became

subject to tariffs when imported into the United States. This pronouncement imposed tariffs on the wafer substrates we
imported into the United States. The initial tariff rate was 10% and subsequently was increased to 25%. Approximately
10% of our revenue derives from importing our wafers into the United States. In 2020 and 2019, we paid approximately
$1.3 million and $0.7 million, respectively, in tariffs. The future impact of tariffs and trade wars is uncertain.

We were incorporated in California in December 1986 and reincorporated in Delaware in May 1998. The
Company went public in 1998. We changed our name from American Xtal Technology, Inc. to AXT, Inc. in July 2000. Our
principal corporate office is located at 4281 Technology Drive, Fremont, California 94538, and our telephone number at
this address is (510) 438-4700.

Industry Background

Certain electronic and opto-electronic applications have performance requirements that exceed the capabilities of

conventional silicon substrates, also known as wafers, and often require high-performance compound wafers (mixture of
two materials) or single element wafer substrates. Examples of higher performance non-silicon based wafer substrates
include GaAs, InP, gallium nitride (GaN), silicon carbide (SiC) and Ge. One of the earliest broadly used alternative wafer
substrates was GaAs and GaAs wafer substrates were the earliest wafer substrates we produced.

Silicon substrates dominate the semiconductor substrate market. Silicon wafers are larger in diameter and 

significantly lower in cost. AXT and our competitors exist because the laws of physics prevent certain functions from 
performing properly, or at all, if silicon material is used as the wafer substrate.   Our substrate wafers are used when a 
typical silicon substrate wafer cannot meet the performance requirements of a semiconductor or optoelectronic device. 
Demand for higher performance non-silicon-based wafer substrates, such as the substrates in which AXT specializes, is 
expected to increase as new applications are adopted. In contrast to the ever-more complex electronic circuit designs and 
the skill sets required to accomplish such designs, the knowledge base and skill sets required for AXT and our competitors 
are material science-based. We do not design or manufacture the semiconductor chips and other electronic circuits. Instead 
we apply our deep knowledge in material science to grow single crystal ingots that are then sliced into individual wafer 
substrates.  We add value by researching, developing and producing the specialty material wafers. This places us at the 
beginning of the semiconductor “food chain”.

InP is a high-performance semiconductor substrate used in broadband and fiber optic applications and data center
connectivity. InP substrates can also be used in 5G applications. In recent years, InP demand has increased. Semi-insulating
GaAs substrates are used to create various high-speed microwave components, including power amplifier chips used in cell
phones, satellite communications and broadcast television applications. Semi-conducting GaAs substrates are used to
create opto-electronic products, including high brightness light emitting diodes (HBLEDs) that are often used to backlight
wireless handsets and liquid crystal display (LCD) TVs and also used for automotive panels, signage, display and lighting
applications. A new application for semi-conducting GaAs substrates is 3-D sensing chips using VCSELs (vertical cavity
surface emitting lasers) as an array of lasers on a single chip that can be used in cell phones and other devices. Ge
substrates are used in applications such as solar cells for space and terrestrial photovoltaic applications.

The AXT Advantages

We believe that we benefit from the following advantages:

● New facilities, equipment and added capacity.  We believe we are the only company in our industry to have 

recently added significant new facilities, equipment and capacity.  Although current customers and 
prospective customers previously viewed our relocation process as a risk, we believe our progress and 
success in managing this process now position us as the “go to” supplier with a state of the art manufacturing 
line, a proven ability to add capacity and a commitment to continuous improvement.

● Funds from the recent private equity investments in Tongmei and additional funds from the anticipated future 
IPO of Tongmei are viewed favorably by our customers and prospective customers.  New applications using 
InP and GaAs wafer substrates could require significant capital investments to add capacity, purchase and 
install advanced process and test equipment or construct additional facilities.  We believe customers view the 
funds recently raised, and intended to be raised in the IPO, as a sign of our commitment to meet their needs 
and to deploy this capital to increase capacity as needed.

● Key leadership in InP technology and revenue growth.  We believe our InP wafers have the lowest defect
densities, stress and slip lines on the market, enabling our customers to achieve the highest wafer fab and
device yields. We have developed a strong base of proprietary InP technology that we continue to expand.
There are significant barriers to entry in the InP substrate market and currently, there are only three primary

7

Table of Contents

suppliers, including AXT. We believe that this market will continue to expand and grow.  We intend to 
promote our track record of successfully adding capacity as the market expands.

● Key provider of low defect density GaAs wafer substrates.  In recent years customer demand for low etch pit
density (“EPD”) GaAs wafer substrates has increased, particularly for LED lighting, the deployment of 3-D
sensing for facial recognition in cell phones and world facing camera technology in cell phones. The
requirement of low EPD is a barrier to entry and we believe there are a limited number of potential substrate
providers that can meet this requirement, including AXT. As we qualify low EPD wafers from our new
location, we believe the quality of our low EPD wafers and our ability to expand manufacturing capacity
quickly will enable us to support new applications and generate additional revenue.

● Proprietary process technology drives manufacturing.  In our industry, the single crystal growth process and
the wafer manufacturing process incorporate proprietary process technology. We have a substantial body of
proprietary process technology and we believe this gives us a competitive advantage, especially in InP. This
also creates a barrier to entry.

● Low-cost manufacturing operation in China.  Since 2004, we have manufactured all of our products in

China, which generally has favorable costs for facilities and labor compared to costs of comparable facilities
and labor in the United States, Japan or Europe. As of December 31, 2020, 1,046 of our 1,074 employees
(including employees at our Beijing, Kazuo and Dingxing facilities as well as our consolidated raw material
companies) were located in China. Our primary competitors have their major manufacturing operations in
Germany or Japan. Our presence in China also enables us to closely manage our raw materials supply chain.

● We believe that we are the only compound semiconductor substrate supplier to have a position in raw

materials. We have partial ownership of raw material companies in China that form an integral part of our 
supply chain.  We believe our subsidiaries and raw material companies in China provide us with a more 
reliable supply of, and shorter lead-times for, the raw materials central to our final manufactured products 
compared to third-party providers. We believe that this dedicated supply chain will enable us to meet 
increases in demand from our customers by providing an increased volume of raw materials quickly, 
efficiently and cost effectively.

● Our diverse product offering results in a broader range of customers and applications. We offer a diverse
range of products and are able to provide custom-defined products that meet our customers’ specifications.
We have a strong technical sales support team that engages with our customers and understands their product
requirements. A significant percentage of the members of our team that engage with customers have PhDs in
physics or materials science. This combination of technical sales strength and our willingness to accept our
customers’ unique product specifications results in a broad range of customers and applications.

● Enhanced revenue diversity through the sale of raw materials. Our strategy allows our consolidated

subsidiaries to also sell raw materials in the open market to third parties. Revenue from non-substrate
products provides further diversity in our customer base and business model.

● Business model unique among current competitors. We believe we are the only publicly traded company

producing InP, GaAs and Ge wafer substrates. Our direct competitors are either privately owned companies
or divisions within very large companies that are publicly listed in Japan. We believe the combination of
access to U.S. and China capital markets, U.S.-based product quality standards, China-based manufacturing
and a unique strategy for the supply of many of the raw materials we need is a competitive advantage as well
as an attractive business model to our customers.

Strategy

Our goal is to become the leading worldwide supplier of high-performance compound and single element 

semiconductor substrates.  Key elements of our strategy include:

Promote our strengths in InP. As cloud-based data centers continue to combine integrated circuits and InP-based

lasers to transfer data through light, we believe there will be increased demand for InP substrates. More recently InP is
being used in 5G infrastructure. Future applications could include driverless cars and 5G in cell phones.

Add InP capacity and continue InP R&D. We are continuing to add manufacturing capacity for InP to support
the growth for this product line. End market applications using our wafer substrate products often have long product life
cycles. We believe the end market applications using InP could have product life cycles that are similar to the long product
life cycles of end market applications using GaAs. In addition to adding manufacturing capacity, we are continuing to
invest in InP crystal growth technology and wafer processing technology. For example, we are developing six-inch
diameter ingots and improving the relative flatness of the wafer surface to improve performance.

Qualify the new facilities for GaAs based 3-D and Time of Flight sensing array applications in mobile devices.  

Although 3-D sensing has not yet been widely adopted and embraced, we believe its use in world-facing cameras will 
accelerate adoption and generate a significant impact for high-quality GaAs suppliers.  We believe 3-D sensing technology 
will also be used as sensors in driverless automobiles.  The GaAs substrate requirements for 3-D sensing applications 
include very low defect densities or etch pitch densities. We intend to capture opportunities in these markets by promoting 
our strengths and capabilities.

Create customer awareness that the new facilities are designed to allow us to add equipment and capacity

rapidly.  The construction of new facilities and infrastructure takes much longer to complete in comparison to the
installation of furnaces and other manufacturing equipment. We have proven our ability to do both and we believe this
ability makes us an attractive supplier for customers.

Offer diverse products, including custom products.  We believe AXT has a reputation in the market for providing 
a broad range of products, including custom products that are supported by a team of technical sales support professionals, 
the majority of whom hold advanced graduate degrees in physics or materials science. We plan to further promote this 
brand image as a way to differentiate ourselves in the market.  We believe this strategy will lead to a more diverse customer 
base and higher volumes.

Sustain manufacturing efficiencies.  We seek to continue to leverage our China-based manufacturing advantage
by increasing efficiencies in our manufacturing methods, systems and processes. Our strategy is to combine the benefits of
U.S. quality control systems and access to U.S. and China capital markets with our China-based manufacturing operations.
We promote the concept and practice of continuous improvement within our company culture.

Increase productivity and seek profitability in our subsidiaries/consolidated raw material companies.  The

supply and demand equation for specialty materials can be complex and volatile. Over the years, we have established or
invested in raw material companies in China that are an integral part of our supply chain. We will continue to provide
strategic support to these companies and they, in turn, will continue to be the backbone of our supply chain. We plan to
work closely with these companies to increase their productivity and improve their financial performance as they continue
to support our supply chain.

Materials of the future.  The specialty materials substrate market is dynamic and subject to continued changes 
and cycles.  We plan to use our deep knowledge and experience in specialty materials and wafer substrates to seek new 
applications for existing substrates in our portfolio and explore additional materials that may be synergistic with our 
knowledge base, customer needs and manufacturing lines.

Technology

Wafer substrates on which integrated circuits and optical devices are fabricated serve as a foundation for
semiconductor device fabrication. Wafers are derived from ingots that are grown in a cylindrical form. The diameter and
length of an ingot will vary depending on the type of material and the growth process used. An ingot can be single-
crystalline (a single crystal) or multi-crystalline (polycrystalline). A single crystal is a continuous lattice of atoms with no
boundaries within the structure. The ingot must be a single crystal in order for it to be useful in making wafers for device
fabrication. A single crystal ingot can be made from a single element such as germanium or silicon, or it can be made from
two or more elements such as gallium arsenide (with gallium and arsenic) or indium phosphide (with indium and
phosphorous). Depending on physical properties of the materials in a wafer, the performance of devices and circuits can be
remarkably different.

AXT uses its proprietary vertical gradient freeze (VGF) technology for growing single crystal Indium Phosphide 
(InP), Gallium Arsenide (GaAs) and Germanium (Ge) ingots. After growing the crystalline ingot, the ingot is then sliced 
into individual substrates or wafers.  Before specialty material wafers can be used, a thin layer of structured chemicals is 
grown on the surface of the substrate. This is called an epitaxial layer. We sell the majority of our substrates to companies 
that specialize in applying the epitaxial layer. The wafers are then used to produce state-of-the-art electronic and opto-
electronic devices and circuit applications.

InP and GaAs compounds are formed by combining elements from Groups III and V in the periodic table of 

elements, whereas Ge is a Group IV elemental material.  Each of these materials has unique properties that determine the 
best device and/or circuit applications.  As a result of their special high electron mobility combined with their direct ban-
gap properties, both InP and GaAs wafers have enjoyed dominant roles in the production of light-emitting diodes (LEDs), 
solid-state lasers and power amplifiers for mobile phones, to name a few applications.  Ge wafers, on the other hand, have 
played a key role in the manufacturing of special solar cells known as triple junction solar cells (TJSCs) for space and 
terrestrial power generation.      

With the recent evolution in several applications, InP lasers are projected to play a dominant role in the 
optoelectronics arena, e.g. silicon photonics (where InP lasers are a key component) and autonomous cars (where special 
wavelength InP-based lasers are used for object sensing and collision avoidance). Crystal growth process technology 
frequently contains steps and procedures that are considered proprietary secrets held by the producer, often including 
methods to control the temperature within the crucible.  InP crystal growth relies on extreme pressure within the crucible. 
As such it requires not only temperature control methodologies, but also pressure control and stabilization process 
methodologies, many of which AXT considers proprietary trade secrets. It is this combination of variables and the required 
methods to control them that create a barrier to entry. We believe our long-term investment in InP research and 
development has resulted in a substantive body of proprietary knowledge.

After growing the crystalline ingot, the material is then sliced into individual substrates or wafers. We have

continued to invest in wafer processing technology covering each step in the process from sawing to edge smoothing to
final cleaning and we believe we have technology and trade secrets addressing the scope of wafer processing. One focus in
our recent development programs has been on automation, particularly in cleaning the wafers.

Ideally, all the atoms in a wafer or substrate are arrayed in a specific periodic order.  However, sensitivities in the 

ingot growth process will cause some atoms to be improperly aligned and these are referred to as dislocations.  The 
aggregate number of dislocations in a wafer is referred to as the dislocation density.  Dislocation densities can be seen as a 
group of tiny marks or pits under a microscope by etching the wafer with acid and each wafer has an etch pit density or 
EPD.  Certain micro devices, such as the array used for 3-D sensing, require wafers with very low EPD. AXT considers the 
process technology we use to achieve low EPD as proprietary process technology and we believe we are one of only a few 
substrate manufacturing companies that can produce low EPD wafers.

Products

We have two product lines: specialty material substrates and raw materials integral to these substrates. We design,

develop, manufacture and distribute high-performance semiconductor substrates, also known as wafers. Through

10

Table of Contents

the two consolidated subsidiaries in our supply chain, we also sell certain raw materials. InP is a high-performance
semiconductor substrate used in fiber optic lasers and detectors, passive optical networks (PONs), telecommunication, now
expanding to include 5G, metro and data center connectivity, silicon photonics, photonic ICs (PICs), terrestrial solar cell
(CPV), lasers, RF amplifiers (military wireless), infrared motion control and infrared thermal imaging. We make semi-
insulating GaAs substrates used in making semiconductor chips in applications such as power amplifiers for wireless
devices, high-performance transistors and high efficiency solar cells for drones. Our semi-conducting GaAs substrates are
used to create opto-electronic products, which include High Brightness LEDs that are often used to backlight wireless
handsets and LCD TVs and for automotive, signage, display and lighting applications, as well as high power industrial
lasers for material processing (welding, cutting, drilling, soldering, marking and surface modification). Our semi-
conducting GaAs substrates could be used to create opto-electronic products for 3-D sensing using VCSELs. Ge substrates
are used in emerging applications, such as triple junction solar cells for space and terrestrial photovoltaic applications and
for optical applications.

Substrates.  We currently sell compound substrates manufactured from InP and GaAs, as well as single-element 
substrates manufactured from Ge. We supply InP substrates in two-, three- and four-inch diameters, and Ge substrates in 
two-, four- and six-inch diameters. We supply both semi-insulating and semi-conducting GaAs substrates in one-, two-, 
three-, four-, five- and six-inch diameters. Many of our customers require customized specifications, such as special levels 
of iron or sulfur dopants or a special wafer thickness.

Raw Materials. Our two consolidated raw material subsidiaries produce and sell certain raw materials, some of 

which are used in our substrate manufacturing process and some of which are sold to other companies. One of these 
consolidated companies produces pBN crucibles and the other consolidated company converts raw gallium to purified 
gallium and produces InP base material.  

We promote our product diversity as a way to differentiate ourselves in the market. Some competitors provide 

only gallium arsenide substrates. We provide gallium arsenide and also indium phosphide and germanium substrates.  
Some competitors limit their wafer diameters to only a few sizes. Our wafers range from one inch to up to six inches in 
diameter. We also produce substrates with customer defined specifications, which may range in thickness, smoothness or 
flatness and may include adding special additional materials, such as iron or sulfur. In addition to our wafers or substrates, 
we also generate revenue from our two consolidated subsidiaries that sell raw materials. Product diversity can mitigate 
some of the down cycles in our market because we are not dependent on a single product or application for revenue.    

Customers

Before specialty material wafers can be processed in a typical wafer manufacturing facility that constructs the

electronic circuit, laser or optical device on a chip, a thin layer of structured chemicals is grown on the surface of the
substrate. This is called an epitaxial layer. We sell our substrates to companies that apply the epitaxial layer, who then in
turn sell the modified wafers to the wafer fabs, chip design companies, LED manufacturers and others. Some customers do
both the epitaxial layer and wafer fabrication.

Epitaxial layer companies that form our customer base are located in Asia, the United States and Europe.  We also 
sell our products to universities and other research organizations that use specialty materials for experimentation in various 
aspects of semi-conducting and semi-insulating applications. Our customers that purchase raw materials are located in 
Asia, the United States and Europe. 

We have at times sold a significant portion of our products in any particular period to a limited number of

customers. One customer, Landmark, represented 11%, 15% and 13% of our revenue for the years ended December 31,
2020, 2019 and 2018, respectively. Our top five customers, although not the same five customers for each period,
represented 32% of our revenue for the year 2020, 40% of our revenue for 2019 and 35% of our revenue for 2018.

For the year ended December 31, 2020, three customers of our consolidated subsidiaries, in aggregate, accounted
for 31% of raw material sales. For the year ended December 31, 2019, three customers of our consolidated subsidiaries, in
aggregate, accounted for 48% of raw material sales and in 2018, three customers accounted for 30% of

11

Table of Contents

raw material sales. Our subsidiaries and consolidated raw material companies are a key strategic benefit for us as they
further diversify our sources of revenue.

Manufacturing, Raw Materials and Supplies

We manufacture all of our products in China. We believe this location generally has favorable costs for facilities

and labor compared to the United States or compared to the location of some of our competitors in Japan and Germany.

We use a two-stage wafer manufacturing process. The first stage deploys our VGF technology for the crystal 
growth of single element or compound element ingots in diameters currently ranging from one inch to six inches.  The 
growth process occurs in high temperature furnaces built using our proprietary designs. Growing the crystalline elements 
into cylindrical ingots takes a number of days, depending on the diameter and length of the ingot produced. The crystal 
growth stage utilizes AXT proprietary process technology. The second stage includes slicing or sawing the ingot into 
wafers or substrates, then processing each substrate to strict specifications, including grinding to reduce the thickness, 
beveling the edges, and then polishing and cleaning each substrate. Many of the wafer processing steps use chemical baths 
and properly cleaning the wafer is a critical process. The wafer processing stage also utilizes AXT proprietary process 
technology.

Wafers from each ingot will include some material that does not meet specifications or quality standards. Defects
may occur as a result of inherent factors in the materials used in the crystalline growth process. They may also result from
variances in the manufacturing process. We have many steps in our line that are partially or fully automated but other
manufacturing steps are performed manually. We intend to increase the level of automation, particularly in cleaning the
wafers. In 2015, we purchased wafer processing equipment from Hitachi Metals to help us increase automation in our
production line and, therefore, reduce variability and defects. In addition, we secured a manufacturing license from Hitachi
Metals. This license includes detailed work instructions for using the equipment purchased and allows us to apply the
licensed proprietary wafer processing technology at any step and on any form of equipment in our line. Due to potential
defects, yield is a key factor in our manufacturing cost. Other key elements are the initial cost of the raw material elements,
manufacturing equipment, factory loading, facilities and labor.

Together with certain subsidiaries we have partial ownership of 10 raw material companies in China that form the

backbone of our supply chain model. These companies generally provide us with reliable supply, market trend visibility,
and shorter lead-times for raw materials central to our manufactured products, including gallium, gallium alloys, indium
phosphide poly-crystal, arsenic, germanium, germanium dioxide, high purity arsenic, pBN and boron oxide. We believe
that these raw material companies have been and will continue to be advantageous in allowing us to procure materials to
support our planned growth. In addition, we purchase supply parts, components and raw materials from several other
domestic and international suppliers. We depend on a single or limited number of suppliers for certain critical materials
used in the production of our substrates, such as quartz tubing, arsenic and polishing solutions. We generally purchase our
materials through standard purchase orders and not pursuant to long-term supply contracts.

Sales and Marketing

We sell our substrate products directly to customers through our direct salesforce in the United States, China and
Europe. We also use independent sales representatives and distributors in Japan, Taiwan, Korea and other areas. Our direct
salesforce is knowledgeable in the use of compound and single-element substrates. Specialty material wafers are
scientifically complicated. Our application engineers must work closely with customers during all stages of our wafer
substrate manufacturing process, from developing the precise composition of the wafer substrate through manufacturing
and processing the wafer substrate to the customer’s specifications. We believe that maintaining a close relationship with
customers and providing them with engineering support improves customer satisfaction and provides us with a competitive
advantage in selling. A significant percentage of the members of our technical sales support team who frequently engage
with customers have PhDs in physics or materials science.

International Sales.  International sales are a substantial part of our business. Sales to customers outside North 
America (primarily the United States) accounted for approximately 90% of our revenue during each of 2020, 2019 and 

12

Table of Contents

2018. The primary markets for sales of our substrate products outside of North America are to customers located in Asia 
and Western Europe. We occasionally receive small orders from customers located in Israel and Russia.

Our raw material companies sell specialty raw materials including 4N, 5N, 6N, 7N and 8N gallium, boron oxide,
germanium, arsenic, germanium dioxide, pyrolytic boron nitride crucibles used in crystal growth, parts for MBE and parts
used in manufacturing OLED rings. Each raw material company has its own separate sales force and sells directly to its
own customers in addition to selling raw materials to us.

Research and Development

To maintain and improve our competitive position, we focus our research and development efforts on designing 

new proprietary processes and products, improving the performance of existing products, achieving new lows in EPD, 
increasing yields and reducing manufacturing costs. We also conduct research and development focusing on larger 
diameter wafers and, in our history, we have consistently developed new products based on larger wafer diameters.  Crystal 
growth of specialty earth materials becomes significantly more difficult as the ingot diameter increases because a 
consistent temperature, and in the case of InP, consistent control of pressure, must be applied over a larger surface area.  In 
2015, we acquired certain proprietary InP crystal growth technology and equipment from Crystacomm.

Certain micro devices, such as the array used for 3-D sensing, require GaAs wafers with very low etch pit density.  
In anticipation of a growth in demand for low EPD six-inch wafers, we have focused our development efforts on increasing 
our yield of such wafers.  

Our current substrate research and development activities focus on continued development and enhancement of 

GaAs, InP and Ge substrates, including improved yield, enhanced surface and electrical characteristics and uniformity, 
greater substrate strength and increased crystal length.  In 2015, we acquired proprietary wafer processing equipment from 
Hitachi Metals. The Hitachi Metals purchase includes a license covering the use of the proprietary equipment and Hitachi 
Metals’ proprietary wafer processing technology. A particular focus of the equipment and process technology is on 
cleaning the wafers.  It is important to remove any residual cleaning agents from each wafer to ensure that the epitaxial 
growth process is not encumbered by residual chemicals on the wafer.

Our consolidated subsidiaries conduct research and development, focusing on gallium alloys, gallium refinement

and pyrolytic boron nitride crucibles used in high temperature crystal growth.

We have assembled a multi-disciplinary team of skilled scientists, engineers and technicians to meet our research
and development objectives. Research and development expenses were $7.1 million in 2020, compared with $5.8 million
in 2019 and $5.9 million in 2018. Development work focusing on yield, continuous improvement and other matters related
to our research and development efforts also occurs within regular manufacturing processes. These costs are included in
our cost of revenue because it is difficult to isolate them as research and development.

Competition

The semiconductor substrate industry is characterized by narrow technological boundaries, price erosion and

generally intense competition. Certain wafer substrates, such as low-quality wafer substrates for consumer products using
LED lighting, compete almost entirely on price. Other products, such as InP and low EPD GaAs wafers, have fewer
competitors and quality is a key competitive factor in addition to price. We face actual and potential competition from a
number of established companies who have the advantages of greater name recognition and more established relationships
in the industry. In some cases, our competitors have substantially greater financial, technical and marketing resources as
they are divisions of much larger companies. They may utilize these advantages to expand their product offerings more
quickly, adapt to new or emerging technologies and changes in customer requirements more quickly, and devote greater
resources to the marketing and sale of their products. We believe a critical factor in our business is the level of technical
support we provide to the customer or prospective customer and we attempt to counter possible advantages of name
recognition or size with superior technical support through our team of technical sales support professionals, the majority
of whom hold PhDs in physics or materials science.

13

Table of Contents

We believe that the primary competitive factors in the markets in which our substrate products compete are:

● quality;

● price;

● customer technical support;

● performance;

● meeting customer specifications; and

● manufacturing capacity.

Our ability to compete in target markets also depends on factors such as:

● the timing and success of the development and introduction of new products, including larger diameter

wafers, and product features by us and our competitors;

● the availability of adequate sources of raw materials;

● protection of our proprietary methods, systems and processes;

● protection of our products and processes by effective use of intellectual property laws; and

● general economic conditions, which impact end markets using substrates.

A majority of our customers specialize in epitaxial growth, a complex series of chemical layers grown on top of

our wafers. Typically, our customer or prospective customer has at least two qualified substrate suppliers. Qualified
suppliers must meet industry-standard specifications for quality, on-time delivery and customer support. Once a substrate 
supplier has qualified with a customer, price, consistent quality and current and future product delivery lead times become 
the most important competitive factors. A supplier that cannot meet a customer’s current lead times or that a customer 
perceives will not be able to meet future demand and provide consistent quality can lose market share. Our primary 
competition in the market for compound and single element semiconductor substrates includes Sumitomo Electric 
Industries (“Sumitomo”), Japan Energy (“JX”), Freiberger Compound Materials (“Freiberger”), Umicore, and China 
Crystal Technology Corp. (“CCTC”). We believe that at least two of our competitors are shipping high volumes of GaAs 
substrates manufactured using a process similar to our VGF technology. In addition, we also face competition from 
semiconductor device manufacturers that may use other specialty material substrates that are not GaAs, InP or Ge based 
materials and that are actively exploring alternative materials. For example, silicon-on-insulator (“SOI”) technology, a 
silicon wafer technology that produces satisfactory devices at lower cost, has been proven in the market. From 2012 to 
2015, SOI technology displaced GaAs chips in key sectors, primarily the radio frequency (“RF”) switching function in cell 
phones.  

Because of our vertically integrated, sophisticated supply chain, we believe we are the only compound 
semiconductor substrate supplier to offer a broad suite of raw materials. We believe this gives us a unique competitive 
advantage because we have greater control and stability over many of our needed materials.  Further, we believe we have 
some advantage in manufacturing costs. In the event of a significant increase in demand we believe our raw materials 
supply chain strategy and our ability to rapidly increase capacity can provide us some advantage. 

14

Table of Contents

Intellectual Property

Our success and the competitive position of our VGF technology depend on our ability to maintain our proprietary

process technology secrets and other intellectual property protections. We rely on a combination of patents, trademark and
trade secret laws, non-disclosure agreements and other intellectual property protection methods to protect our proprietary
technology. We believe that, due to the rapid pace of technological innovation in the markets for our products, our ability to
establish and maintain a position of technology leadership depends as much on the skills of our research and development
personnel as upon the legal protections afforded our existing technologies. To protect our trade secrets, we take certain
measures to ensure their secrecy, such as executing non-disclosure agreements with our employees, customers and
suppliers. However, reliance on trade secrets is only an effective business practice insofar as trade secrets remain
undisclosed and a proprietary product or process is not reverse engineered or independently developed.

In addition to proprietary process trade secrets, we also file patents. To date, we have been issued 56 patents

related to our VGF products and processes; 34 in China, nine in the United States, seven in Japan, two in Taiwan, two in
the European Union, one in Canada and one in South Korea. Patents normally have a protected life of 20 years from their
filing dates. Our patents have expiration dates ranging from 2021 to 2037.  In some cases we may consider filing
divisional, continuation or continuation-in-part of the existing patents for additional claims. We currently have five patent
applications pending, including three in China, one in the United States and one in Europe. Furthermore, in aggregate, our
consolidated raw material companies have been issued 61 patents in China, including 42 patents issued to BoYu and 19
patents issued to JinMei.

In the normal course of business, we periodically receive and make inquiries regarding possible patent
infringement. In dealing with such inquiries, it may become necessary or useful for us to obtain or grant licenses or other
rights. However, there can be no assurance that such licenses or rights will be available to us on commercially reasonable
terms. If we are not able to resolve or settle claims, obtain necessary licenses on commercially reasonable terms and/or
successfully prosecute or defend our position, our business, financial condition and results of operations could be
materially and adversely affected.

Environmental Regulations

We are subject to federal, state and local environmental and safety laws and regulations in all of our operating 

locations, including laws and regulations of China, such as laws and regulations related to the development, manufacture 
and use of our products, the use of hazardous materials, the operation of our facilities, and the use of the real property. 
These laws and regulations govern the use, storage, discharge and disposal of hazardous materials during manufacturing, 
research and development and sales demonstrations. We maintain a number of environmental, health and safety programs 
that are primarily preventive in nature. As part of these programs, we regularly monitor ongoing compliance. If we fail to 
comply with applicable regulations, we could be subject to substantial liability for clean-up efforts, personal injury, fines or 
suspension or be forced to cease our operations, and/or suspend or terminate the development, manufacture or use of 
certain of our products, the use of our facilities, or the use of our real property, each of which could have a material adverse 
effect on our business, financial condition and results of operations.  The regulatory landscape shifts and changes in China 
as that country attempts to address its environmental pollution. Because we manufacture all of our products in China, we 
are subject to an evolving set of regulations that could require changes in our equipment and processes and require us to 
obtain new permits. In 2017, China increased its focus on environmental concerns which increased pressure on 
manufacturing companies. During periods of severe air pollution in Beijing, manufacturing companies, including AXT, 
may be ordered by the local government to stop production for several days.  For example, in the first quarter of 2018, over 
300 manufacturing companies, including AXT, were intermittently shut down by the local government for a total of ten 
days from February 27 to March 31, due to severe air pollution.

15

Table of Contents

Human Capital

As of December 31, 2020, AXT and Tongmei had 784 employees, which consisted of 27 employees in our

headquarters in Fremont, California, one sales professional in France and 756 employees in our factories in China. In
addition, our two consolidated raw material companies had, in total, 290 employees. In aggregate, we and our consolidated
raw material companies had 1,074 employees, of whom 882 were principally engaged in manufacturing, 112 in sales and
administration and 80 in research and development. Of these 1,074 employees, 27 were located in the United States, one in
France and 1,046 in China.

We believe that our future success largely depends upon our continued ability to attract and retain highly skilled

employees. We provide our employees with competitive salaries and bonuses, opportunities for equity ownership,
development programs that enable continued learning and growth and a robust employment package that promotes well-
being across all aspects of their lives, including health care and paid time off. Most of our employees in China are
represented by unions. As of December 31, 2020, 881 employees in China, including employees of our two consolidated
raw material companies, were represented by unions. We have never experienced a work stoppage and we consider our
relations with our employees to be good.

I.

Summary Risk Factors

● Our NASDAQ stock price is volatile and our stock price could decline.  Unpredictable fluctuations in our 

operating results, changes and events in our end markets and global trends cause volatility in our stock price.
● COVID-19 or other contagious diseases may affect our business operations and financial performance.  Lack of 

supply of vaccines and resistance by some to be vaccinated could prolong COVID-19.

● Global economic and political conditions, including trade tariffs and restrictions from China, may have a negative

impact on our business and financial results.

● Changes in China’s political, social, regulatory or economic environments may affect our financial performance.
● Our gross margin has fluctuated historically and may decline due to several factors.  Factors such as product mix, 
unit volume, yields and other manufacturing efficiencies can cause our gross margin to decrease or increase from 
quarter to quarter.

● The proposed Tongmei IPO on the STAR Market in China could fail to be completed. This could result in
investor disappointment and in failure to secure sufficient capital needed to take advantage of market
opportunities for our products. Our stock price could decline.

●  The terms of the private equity raised by Tongmei in China grant each investor a right of redemption if Tongmei 
fails to achieve the IPO on or before December 31, 2022.  This could result in disgorging the cash that we raised 
from the investors.

● Defects in our products could diminish demand for our products. Our ability to receive orders from tier one 
customers is contingent on producing wafer substrates of very high quality and deploying best practices in 
manufacturing.  We may not always be able to meet these requirements and we could then lose revenue.
● Difficulties in accurately estimating market demand could result in over-investing in equipment and capacity

expansion or losing market share if we do not invest sufficiently.

● Attracting and retaining tier one customers requires that we succeed in our research and development programs.  
Customers establish difficult to meet product specifications regarding defect densities, surface flatness diameter 
size and other specifications pushing the boundaries of material science.  We may not achieve these 
specifications.

● We are subject to foreign exchange gains and losses that materially impact our income statement.  Because we are 
a global company we are exposed to changes and swings in foreign exchange, particularly when currencies 
experience periods of volatility.

General Risk Factors

Silicon substrates (wafers) are significantly lower in cost compared to substrates made from specialty materials, such as
those that we produce, and new silicon-based technologies could enable silicon-based substrates to replace specialty
material-based substrates for certain applications.

Historically silicon wafers or substrates are less expensive than specialty material substrates, such as those that we 

produce.  Electronic circuit designers will generally consider silicon first and only turn to alternative materials if silicon 
cannot provide the required functionality in terms of power consumption, speed, wave lengths or other specifications.  
Beginning in 2011, certain applications that had previously used GaAs substrates, specifically the RF chip in mobile 
phones, adopted a new silicon-based technology called silicon on insulator, or SOI. SOI technology uses a silicon-
insulator-silicon layered substrate in place of conventional silicon substrates in semiconductor manufacturing. SOI 
substrates cost less than GaAs substrates and, although their performance is not as robust as GaAs substrates in terms of 
power consumption, heat generation and speed, they became acceptable in mobile phones and other applications that were 
previously dominated by GaAs substrates.  The adoption of SOI resulted in decreased GaAs wafer demand, and decreased 
revenue. If SOI or new silicon-based technologies gain more widespread market acceptance, or are used in more 
applications, our sales of specialty material-based substrates could be reduced and our business and operating results could 
be significantly and adversely affected.

COVID-19 or other contagious diseases may affect our business operations and financial performance.

The spread of COVID-19 has impacted our operations and financial performance. This outbreak has triggered

references to the SARS outbreak, which occurred in 2003 and affected our business operations. Any severe occurrence of
an outbreak of a contagious disease such as COVID-19, SARS, Avian Flu or Ebola may cause us or the government to
temporarily close our manufacturing operations in China. In January 2020, virtually all companies in China were ordered
to remain closed after the traditional Lunar New Year holiday ended, including our subsidiaries in China. If there is a
renewed surge of the COVID-19 pandemic in China, the Chinese government may require companies to close again. If one
or more of our key suppliers is required to close for an extended period, we might not have enough raw material
inventories to continue manufacturing operations. In addition, travel restrictions between China and the U.S. have
disrupted our normal movement to and from China and this has impacted our efficiency. If COVID-19 vaccines are not
widely available, our business operations may be affected negatively. The outbreak has affected transportation and reduced
the availability of air transport, caused port closures, and increased border controls and closures. If our manufacturing
operations were closed for a significant period or we experience difficulty in shipping our products, we could lose revenue
and market share, which would depress our financial performance and could be difficult to recapture. If one of our key
customers is required to close for an extended period, this may delay the placement of new orders. As a result, our revenue
would decline. Further, customers might default on their obligations to us. In the first quarter of 2020 we observed an
increase in our accounts receivable and believe this was the result of businesses slowing down and a general cautiousness
due to the COVID-19 pandemic. Such events would negatively impact our financial performance.

Our gross margin has fluctuated historically and may decline due to several factors.

Our gross margin has fluctuated from period to period as a result of increases or decreases in total revenue, unit

volume, shifts in product mix, shifts in the cost of raw materials, costs related to the relocation of our gallium arsenide and
germanium production lines, including costs related to hiring additional manufacturing employees at our new locations,
tariffs imposed by the U.S. government, the introduction of new products, decreases in average selling prices for products,
utilization of our manufacturing capacity, fluctuations in manufacturing yields and our ability to reduce product costs.
These factors and other variables change from period to period and these fluctuations are expected to continue in the future.
A recent example is that in the second quarter of 2019 our gross margin was 34.3% but it dropped to 21.0% in the fourth
quarter of 2019 as a result of several of these factors.

Further, we do not control the prices at which our raw material companies sell their raw material products to third

parties and we do not control their production process. However, because we consolidate the results of two of these raw
material companies with our own, any reduction in their gross margins could have a significant, adverse impact on our
overall gross margins. One or more of our companies has in the past sold, and may in the future sell, raw materials at
significantly reduced prices in order to gain volume sales or sales to new customers. In addition, at some points in the last
three years, the market price of gallium dropped below our per unit inventory cost and we incurred an inventory write
down under the lower of cost or net realizable value accounting rules.

Shutdowns or underutilizing our manufacturing facilities may result in declines in our gross margins.

An important factor in our success is the extent to which we are able to utilize the available capacity in our
manufacturing facilities. A number of factors and circumstances may reduce utilization rates, including periods of industry
overcapacity, low levels of customer orders, operating inefficiencies, mechanical failures and disruption of operations due
to expansion, power interruptions, fire, flood, other natural disasters or calamities or government-ordered mandatory
factory shutdowns, including as a result of the COVID-19 pandemic. Severe air pollution in Beijing can trigger mandatory
factory shutdowns. For example, in the first quarter of 2018, over 300 manufacturing companies, including AXT, were
intermittently shut down by the local government for a total of ten days from February 27 to March 31, due to severe air
pollution. Further, we have increased capacity by adding two new sites and this could reduce our utilization rate and
increase our depreciation charges. Because many portions of our manufacturing costs are relatively fixed, high utilization
rates are critical to our gross margins and operating results. If we fail to achieve acceptable manufacturing volumes or
experience product shipment delays, our results of operations will be negatively affected. During periods of decreased
demand, we have underutilized our manufacturing lines. If we are unable to improve utilization levels at our facilities
during periods of decreased demand and correctly manage capacity, the fixed expense

18

Table of Contents

levels will have an adverse effect on our business, financial condition and results of operations. For example, in the three
months ended December 31, 2019, our revenue dropped to $18.4 million and our gross margin was only 21.0%.

If we are unable to utilize the available capacity in our manufacturing facilities, we may need to implement a

restructuring plan, which could have a material adverse effect on our revenue, our results of operations and our financial
condition. For example, in 2013, we concluded that incoming orders were insufficient and that we were significantly
underutilizing our factory capacity. As a result, in February 2014, we announced a restructuring plan with respect to our
wafer manufacturing company, Tongmei, in order to better align manufacturing capacity with demand. Under the
restructuring plan, we recorded a charge of approximately $907,000 in the first quarter of 2014.

If we receive fewer customer orders than forecasted or if our customers delay or cancel orders, we may not be able

to reduce our manufacturing costs in the short-term and our gross margins would be negatively affected. In addition, lead
times required by our customers are shrinking, which reduces our ability to forecast orders and properly balance our
capacity utilization.

If we have low product yields, the shipment of our products may be delayed and our product cost and operating results
may be adversely impacted.

A critical factor in our product cost is yield. Our products are manufactured using complex crystal growth and
wafer processing technologies, and the number of usable wafer substrates we produce can fluctuate as a result of many
factors, including:

● poor control of furnace temperature and pressure;

● impurities in the materials used;

● contamination of the manufacturing environment;

● quality control and inconsistency in quality levels;

● lack of automation and inconsistent processing requiring manual manufacturing steps;

● substrate breakage during the manufacturing process; and

● equipment failure, power outages or variations in the manufacturing process.

An example where yield is of special concern is for our six-inch semi-conducting gallium arsenide substrates, 

which can be used for manufacturing opto-electronic devices in cell phones, enabling 3-D sensing.  This application 
requires very low defect densities, also called etch pit densities, or EPD, and our yields will be lower than the yields 
achieved for the same substrate when it will be used in other applications.  If we are unable to achieve the targeted quantity 
of low defect density substrates, then our manufacturing costs would increase and our gross margins would be negatively 
impacted. 

In addition, we may modify our process to meet a customer specification, but this can impact our yields. If our
yields decrease, our revenue could decline if we are unable to produce products to our customers’ requirements. At the
same time, our manufacturing costs could remain fixed, or could increase. Lower yields negatively impact our gross
margin. We have experienced product shipment delays and difficulties in achieving acceptable yields on both new and
older products, and such delays and poor yields have adversely affected our operating results. We may experience similar
problems in the future and we cannot predict when they may occur, their duration or severity.

If our manufacturing processes result in defects in our products making them unfit for use by our customers, our

products would be rejected, resulting in compensation costs paid to our customers, and possible disqualification. This could
lead to revenue loss and market share loss.

Risks exist in utilizing our new gallium arsenide manufacturing sites efficiently.

The Chinese government has imposed, and may impose in the future, manufacturing restrictions and regulations

that require us to move part of our manufacturing operations to a different location or temporarily cease or limit
manufacturing. Such relocation, or other restrictions on manufacturing, could materially and adversely impact our results
of operations and our financial condition.

The Beijing city government is moving its offices to the Tongzhou district where our original manufacturing

facility is currently located. The city government is in the process of moving thousands of government employees into this
area. To create room and upgrade the district, the city instructed virtually all existing manufacturing companies, including
AXT, to relocate all or some of their manufacturing lines. We were instructed to move our gallium arsenide manufacturing
line out of the area.

Although the relocation is largely completed and we are in volume production at the new sites, unforeseen 

manufacturing issues at the new sites could still occur.  Problems could occur as we add capacity or comply with strict 
guidelines as customers perform their qualifications.  All of this will require us to continue to diligently address the many 
details that arise at both of the new sites.  A failure to properly accomplish this could result in disruption to our production 
and have a material adverse impact on our revenue, our results of operations and our financial condition. If we fail to meet 
the product qualification and volume requirements of a customer, we may lose sales to that customer. Our reputation may 
also be damaged. Any loss of sales could have a material adverse effect on our revenue, our results of operations and our 
financial condition.

Some of our key employees are relocating to our new manufacturing sites. Travel restrictions within China

resulting from COVID-19 have impacted their relocation and hindered commuting. Certain employees may choose not to
relocate. If we are unable to continue to employ those key employees in our original manufacturing facility, we may be
required to terminate those employees and could incur severance costs. If the Chinese government does not assist us in this
matter it could materially and adversely impact our results of operations and our financial condition. Further, a loss of key
employees or our inability to hire qualified employees could disrupt our production, which could materially and adversely
impact our results of operations and our financial condition.

The Chinese government has in the past imposed temporary restrictions on manufacturing facilities, such as the 

restrictions imposed on polluting factories for the 2008 Olympics and the 2014 Asian Pacific Economic Cooperation event.  
These restrictions included a shutdown of the transportation of materials and power plants to reduce air pollution. To 
reduce air pollution in Beijing, the Chinese government has sometimes limited the construction of new, or expansion of 
existing, facilities by manufacturing companies in the Beijing area or required mandatory factory shutdowns. For example, 
in the first quarter of 2018, over 300 manufacturing companies, including AXT, were intermittently shut down by the local 
government for a total of ten days from February 27 to March 31 due to severe air pollution. If the government applies 
similar restrictions to us or requires mandatory factory shutdowns in the future, then such restrictions or shutdowns could 
have an adverse impact on our results of operations and our financial condition.  Our ability to supply current or new orders 
could be significantly impacted. Customers could then be required to purchase products from our competitors, causing our 
competitors to take market share from us.

In addition, from time to time, the Chinese government issues new regulations, which may require additional 
actions on our part to comply.  On February 27, 2015, the China State Administration of Work Safety updated its list of 
hazardous substances.  The previous list, which was published in 2002, did not restrict the materials that we use in our 
wafers.  The new list added gallium arsenide.  As a result of the newly published list, we were required to seek additional 
permits.

Additional customers may require that they re-qualify our gallium arsenide wafer substrates or our new sites as a result
of relocating our gallium arsenide manufacturing lines.

Although some of our largest customers have qualified our new sites there may still be some who will decide to
go through the qualification process. If we fail to meet the product qualification requirements of a customer, we may lose
sales to that customer. Our reputation may also be damaged. Any loss of sales could have a material adverse effect on our
revenue, our results of operations and our financial condition.  

20

Global economic and political conditions, including trade tariffs and restrictions, may have a negative impact on our
business and financial results.

In September 2018, the Trump Administration announced a list of thousands of categories of goods that became 

subject to tariffs when imported into the United States.  This pronouncement imposed tariffs on wafer substrates we 
imported into the United States. The initial tariff rate was 10% and subsequently was increased to 25%.  Approximately 
10% of our revenue derives from importing our wafers into the United States.  In the years 2020 and 2019 we paid 
approximately $1.3 million and $0.7 million, respectively, in tariffs.  The future impact of tariffs and trade wars is 
uncertain.

The economic and political conditions between China and the United States, in our view, create an unstable

business environment. The United States has restricted access by certain Chinese technology companies to items produced
domestically and abroad from U.S. technology and software, which may impact our ability to grow our revenue. Trade
restrictions against China have resulted in a greater determination within China to be self-sufficient and produce more
goods domestically. Government agencies in China may be encouraging and supporting the founding of new companies,
the addition of new products in existing companies and more vertical integration within companies. In 2019 these factors
resulted in lower revenue from sales of our wafer substrates in China.

Our operations and financial results depend on worldwide economic and political conditions and their impact on

levels of business spending, which has deteriorated significantly in many countries and regions. Uncertainties in the
political, financial and credit markets may cause our customers to postpone deliveries. The COVID-19 virus is an
additional cause of uncertainty. Delays in the placement of new orders and extended uncertainties may reduce future sales
of our products and services. The revenue growth and profitability of our business depends on the overall demand for our
substrates. Because the end users of our products are primarily large companies whose businesses fluctuate with general
economic and business conditions, a softening of demand for products that use our substrates, caused by a weakening
economy, may result in decreased revenue. Customers may find themselves facing excess inventory from earlier purchases,
and may defer or reconsider purchasing products due to the downturn in their business and in the general economy. If
market conditions deteriorate, we may experience increased collection times and greater write-offs, either of which could
have a material adverse effect on our profitability and our cash flow.

Future tightening of credit markets and concerns regarding the availability of credit may make it more difficult for
our customers to raise capital, whether debt or equity, to finance their purchases of capital equipment or of the products we
sell. Delays in our customers’ ability to obtain such financing, or the unavailability of such financing, would adversely
affect our product sales and revenues and, therefore, harm our business and operating results. We cannot predict the timing,
duration of or effect on our business of any future economic downturn or the timing or strength of any subsequent recovery.

If any of our facilities are damaged by occurrences such as fire, explosion, power outage or natural disaster, we might
not be able to manufacture our products.

The ongoing operation of our manufacturing and production facilities in China is critical to our ability to meet

demand for our products. If we are not able to use all or a significant portion of our facilities for prolonged periods for any
reason, we would not be able to manufacture products for our customers. For example, a fire or explosion caused by our
use of combustible chemicals, high furnace temperatures or, in the case of InP, high pressure during our manufacturing
processes could render some of our facilities inoperable for an indefinite period of time. Actions outside of our control,
such as earthquakes or other natural disasters, could also damage our facilities, rendering them inoperable. If we are unable
to operate our facilities and manufacture our products, we would lose customers and revenue and our business would be
harmed.

On the evening of March 15, 2017, an electrical short-circuit fire occurred at our Beijing manufacturing facility.  

The electrical power supply supporting 2-inch, 3-inch and 4-inch gallium arsenide and germanium crystal growth was 
damaged and production in that area was stopped.  In addition, a waste water pipe was damaged resulting in a halt to wafer 
processing for four days until the pipe could be repaired.  We were able to rotate key furnace hardware and use 

21

Table of Contents

some of the 6-inch capacity for smaller diameter crystal growth production to mitigate the impact of the fire and resume 
production. If we are unable to recover from a fire or natural disaster, our business and operating results could be materially 
and adversely affected.

Demand for our products may decrease if demand for the end-user applications decrease or if manufacturers
downstream in our supply chain experience difficulty manufacturing, marketing or selling their products.

Our products are used to produce components for electronic and opto-electronic products. Accordingly, demand
for our products is subject to the demand for end-user applications which utilize our products, as well as factors affecting
the ability of the manufacturers downstream in our supply chain to introduce and market their products successfully,
including:

● worldwide economic and political conditions and their impact on levels of business spending;

● the competition such manufacturers face in their particular industries;

● end of life obsolescence of products containing devices built on our wafers;

● the technical, manufacturing, sales, marketing and management capabilities of such manufacturers;

● the financial and other resources of such manufacturers; and

● the inability of such manufacturers to sell their products if they infringe third-party intellectual property

rights.

If demand for the end-user applications for which our products are used decreases, or if manufacturers 

downstream in our supply chain are unable to develop, market and sell their products, demand for our products will 
decrease. For example, during 2019 widespread political and economic instability and trade war concerns resulted in a 
general slowdown and our revenue decreased significantly. Additionally, in the second half of 2016, manufacturers 
producing and selling passive optical network devices known as EPONs and GPONs experienced a slowdown in demand 
resulting in surplus inventory on hand. The slowdown persisted until late in 2017.  This resulted in a slowdown of sales of 
our InP substrates used in the PON market.  We expect similar cycles of strong demand followed by lower demand will 
occur for various InP, GaAs or Ge substrates in the future.

Our revenue, gross margins and profitability can be hurt if the average sales price of the various raw materials in our
partially-owned companies decreases.

Although the companies in our vertically integrated supply chain have historically made a positive contribution to 
our financial performance, when the average selling prices for the raw materials produced decline, this results in a negative 
impact on our revenue, gross margin and profitability.  For example, the average selling prices for 4N gallium and for 
germanium were driven down by oversupply in recent years, and negatively impacted our financial results. In 2020, the
companies accounted for under the equity method of accounting contributed a gain of $0.1 million to our consolidated
financial statements. In 2019 and 2018, the companies accounted for under the equity method of accounting contributed a
loss of $1.9 million and $1.1 million, respectively, to our consolidated financial statements. Further, in several quarters
over the past three years, one of our consolidated subsidiaries incurred a lower of cost or net realizable value inventory
write down, which negatively impacted our consolidated gross margin. In the first quarter of 2019, we incurred an
impairment charge of $1.1 million for a germanium materials company in China in which we have a 25% ownership
interest, writing down our investment to zero value. If the pricing environment remains stressed by oversupply and our raw
material companies cannot reduce their production costs, then the reduced average selling prices of the raw materials will
have a continuing adverse impact on our revenue, gross margins and net profit.

22

Table of Contents

Problems incurred in our raw material companies or our investment partners could result in a material adverse impact
on our financial condition or results of operations.

We have invested in raw material companies in China that produce materials, including 99.99% pure gallium (4N
Ga), high purity gallium (6N and 7N Ga), arsenic, germanium, germanium dioxide, pyrolytic boron nitride (pBN) crucibles
and boron oxide (B2O3). We purchase a portion of the materials produced by these companies for our use and they sell the
remainder of their production to third parties. We consolidate the companies in which we have a majority or controlling
financial interest and employ equity accounting for the companies in which we have a smaller ownership interest. Several
of these companies occupy space within larger facilities owned and/or operated by one of the other investment partners.
Several of these partners are engaged in other manufacturing activities at or near the same facility. In some facilities, we
share access to certain functions, including water, hazardous waste treatment or air quality treatment. If a partner in any of
these ventures experiences problems with its operations, or deliberately withholds or disrupts services, disruptions in the
operations of our companies could occur, having a material adverse effect on the financial condition and results of
operation in these companies, and correspondingly on our financial condition or results of operations. For example, since
gallium is a by-product of aluminum, our raw gallium company in China, which is housed in and receives services from an
affiliated aluminum plant, could generate lower production and shipments of gallium as a result of reduced services
provided by the aluminum plant. Accordingly, in order to meet customer supply obligations, our supply chain may have to
source materials from another independent third-party supplier, resulting in higher costs and reduced gross margin.

The China central government has become increasingly concerned about environmental hazards.  Air pollution is 

a well-known problem in Beijing and other parts of China.  In days of severe air pollution, the government has ordered 
manufacturing companies to stop all production.  The central government is also tightening control over hazardous 
chemicals and other hazardous elements such as arsenic, which is produced by two of our raw material companies. Further, 
the central government encourages employees to report to the appropriate regulatory agencies possible safety or 
environmental violations, but there may not be actual violations. Regular use in the normal course of business of hazardous 
chemicals or hazardous elements or a company’s failure to meet the ever-tightening standards for control of hazardous 
chemicals or hazardous elements could result in orders to shut down permanently, fines or other severe measures.  Any 
such orders directed at one of our raw material companies could result in impairment charges if the company is forced to 
close its business, cease operations or incurs fines or operating losses, which would have a material adverse effect on our 
financial results. In the first quarter of 2019, we incurred an impairment charge of $1.1 million for a germanium materials 
company in China in which we have a 25% ownership interest, writing down our investment to zero value.

Further, some of our raw material companies share facilities with our raw material investment partners. If either

company is deemed to have violated applicable laws, rules or regulations governing the use, storage, discharge or disposal
of hazardous chemicals, their operations could be adversely affected and we could be subject to substantial liability for
clean-up efforts, personal injury, fines or suspension or termination of operations. Employees working for these companies
could bring litigation against us even though we are not directly controlling those operations. While we would expect to
defend ourselves vigorously in any litigation that is brought against us, litigation is inherently uncertain and it is possible
that our business, financial condition, results of operations or cash flows could be affected. Even if we are not deemed
responsible for the actions of the raw material companies or investment partners, litigation could be costly, time consuming
to defend and divert management attention; in addition, if we are deemed to be the most financially viable of the partners,
plaintiffs may decide to pursue us for damages.

Intense competition in the markets for our products could prevent us from increasing revenue and achieving
profitability.

The markets for our products are intensely competitive. We face competition for our wafer substrate products

from other manufacturers of substrates, such as Sumitomo, JX, Freiberger, Umicore, and CCTC, and from companies, such
as Qorvo and Skyworks, that are actively considering alternative materials to GaAs and marketing semiconductor devices
using these alternative materials. We believe that at least two of our major competitors are shipping high volumes of GaAs
substrates manufactured using a process similar to our VGF process technology. Other competitors may develop and begin
using similar technology. Sumitomo and JX also compete with us in the InP market. If we are

23

Table of Contents

unable to compete effectively, our revenue may decrease and we may not maintain profitability. We face many competitors
that have a number of significant advantages over us, including:

● greater name recognition and market share in the business;

● more manufacturing experience;

● extensive intellectual property; and

● significantly greater financial, technical and marketing resources.

Our competitors could develop new or enhanced products that are more effective than our products.

The level and intensity of competition has increased over the past years and we expect competition to continue to

increase in the future. Competitive pressures have resulted in reductions in the prices of our products, and continued or
increased competition could reduce our market share, require us to further reduce the prices of our products, affect our
ability to recover costs and result in reduced gross margins and profitability.

In addition, new competitors have and may continue to emerge, such as a crystal growing company established by 
a former employee in China that is supplying semi-conducting GaAs wafers to the LED market. Competition from sources 
such as this could increase, particularly if these competitors are able to obtain large capital investments. Further, recent 
trade tensions between China and the United States have resulted in a greater determination within China to be self-
sufficient and produce more goods domestically.  This could result in the formation of new competitors that would compete 
against our company and adversely affect our financial results.

Cyber-attacks, system security risks and data protection issues could disrupt our internal operations and cause a
reduction in revenue, increase in expenses, negatively impact our results of operation or result in other adverse
consequences.

Like most technology companies, we could be targeted in cyber-attacks. We face a risk that experienced computer

programmers and hackers may be able to penetrate our network security and misappropriate or compromise our
confidential and proprietary information, potentially without being detected. Computer programmers and hackers also may
be able to develop and deploy viruses, worms, and other malicious software programs that attack our information
technology infrastructure and demand a ransom payment. The costs to us to eliminate or alleviate cyber or other security
problems, bugs, viruses, worms, malicious software programs and security vulnerabilities could be significant, and our
efforts to address these problems may not be successful and could result in interruptions and delays that may impede our
sales, manufacturing, distribution, accounting or other critical functions.

Breaches of our security measures could create system disruptions or cause shutdowns or result in the accidental
loss, inadvertent disclosure or unapproved dissemination of proprietary information or sensitive or confidential data about
us. Cyber-attacks could use fraud, trickery or other forms of deception. A cyber-attack could expose us to a risk of loss or
misuse of information, result in litigation and potential liability, damage our reputation or otherwise harm our business. In
addition, the cost and operational consequences of implementing further data protection measures could be significant.

Portions of our information technology infrastructure might also experience interruptions, delays or cessations of

service or produce errors in connection with systems integration or migration work that takes place from time to time,
which may have a material impact on our business. We may not be successful in implementing new systems and
transitioning data, which could cause business disruptions and be more expensive, time consuming, disruptive and
resource-intensive than originally anticipated. Such disruptions could adversely impact our ability to fulfill orders and
interrupt other processes. Delayed sales, lower margins or lost customers could adversely affect our financial results and
reputation.

Table of Contents

The average selling prices of our substrates may decline over relatively short periods, which may reduce our revenue
and gross margins.

Since the market for our products is characterized by declining average selling prices resulting from various 
factors, such as increased competition, overcapacity, the introduction of new products and decreased sales of products 
incorporating our products, the average selling prices for our products may decline over relatively short time periods. We 
have in the past experienced, and in the future may experience, substantial period-to-period fluctuations in operating results 
due to declining average selling prices.  In certain years, we have experienced an average selling price decline of our 
substrate selling prices of approximately 5% to 10%, depending on the substrate product. It is possible that the pace of the 
decline of average selling prices could accelerate beyond these levels for certain products in a commoditizing market. We 
anticipate that average selling prices will decrease in the future in response to the unstable demand environment, price 
reductions by competitors, or by other factors, including pricing pressures from significant customers.  When our average 
selling prices decline, our revenue and gross profit decline, unless we are able to sell more products or reduce the cost to 
manufacture our products. We generally attempt to combat an average selling price decline by improving yields and 
manufacturing efficiencies and working to reduce the costs of our raw materials and of manufacturing our products. We 
also need to sell our current products in increasing volumes to offset any decline in their average selling prices, and 
introduce new products, which we may not be able to do, or do on a timely basis.

In order to remain competitive, we must continually work to reduce the cost of manufacturing our products and

improve our yields and manufacturing efficiencies. Our efforts may not allow us to keep pace with competitive pricing
pressures which could adversely affect our margins. There is no assurance that any changes effected by us will result in
sufficient cost reductions to allow us to reduce the price of our products to remain competitive or improve our gross
margins.

Defects in our products could diminish demand for our products.

Our wafer products are complex and may contain defects, including defects resulting from impurities inherent in
our raw materials or inconsistencies in our manufacturing processes. We have experienced quality control problems with
some of our products, which caused customers to return products to us, reduce orders for our products, or both. If we
experience quality control problems, or experience other manufacturing problems, customers may return product for credit,
cancel or reduce orders or purchase products from our competitors. We may be unable to maintain or increase sales to our
customers and sales of our products could decline. Defects in our products could cause us to incur higher manufacturing
costs and suffer product returns and additional service expenses, all of which could adversely impact our operating results.
If new products developed by us contain defects when released, our customers may be dissatisfied and we may suffer
negative publicity or customer claims against us, lose sales or experience delays in market acceptance of our new products.

Our substrate products have a long qualification cycle that makes it difficult to forecast revenue from new customers or
for new products sold to existing customers.

New customers typically place orders with us for our substrate products three months to a year or more after our

initial contact with them. The sale of our products is subject to our customers’ lengthy internal evaluation and approval
processes. During this time, we may incur substantial expenses and expend selling, marketing and management efforts
while the customers evaluate our products. These expenditures may not result in sales of our products. If we do not achieve
anticipated sales in a period as expected, we may experience an unplanned shortfall in our revenue. As a result, our
operating results would be adversely affected. In addition, if we fail to meet the product qualification requirements of the
customer, we may not have another opportunity to sell that product to that customer for many months or even years. In the
current competitive climate, the average qualification and sales cycle for our products has lengthened even further and is
expected to continue to make it difficult for us to forecast our future sales accurately. We anticipate that sales of any future
substrate products will also have lengthy qualification periods and will, therefore, be subject to risks substantially similar to
those inherent in the lengthy sales cycles of our current substrate products.

25

Table of Contents

The loss of one or more of our key substrate customers would significantly hurt our operating results.

From time to time, sales to one or more of our customers individually represent more than 10% of our revenue

and if we were to lose a major customer the loss would negatively impact our revenue. Our customers are not obligated to
purchase a specified quantity of our products or to provide us with binding forecasts of product purchases. In addition, our
customers may reduce, delay or cancel orders. In the past, we have experienced a slowdown in bookings, significant push-
outs and cancellation of orders from customers. If we lose a major customer or if a customer cancels, reduces or delays
orders, our revenue would decline. In addition, customers that have accounted for significant revenue in the past may not
continue to generate revenue for us in any future period. Any loss of customers or any delay in scheduled shipments of our
products could cause revenue to fall below our expectations and the expectations of market analysts or investors, causing
our stock price to decline.

The cyclical nature of the semiconductor industry may limit our ability to maintain or increase net sales and operating
results during industry downturns.

The semiconductor industry is highly cyclical and periodically experiences significant economic downturns

characterized by diminished product demand, resulting in production overcapacity and excess inventory in the markets we
serve. A downturn can result in lower unit volumes and rapid erosion of average selling prices. The semiconductor industry
has experienced significant downturns, often in connection with, or in anticipation of, maturing product cycles of both
semiconductor companies’ and their customers’ products or a decline in general economic conditions. This may adversely
affect our results of operations and the value of our business.

Our continuing business depends in significant part upon manufacturers of electronic and opto-electronic

compound semiconductor devices, as well as the current and anticipated market demand for these devices and products
using these devices. As a supplier to the semiconductor industry, we are subject to the business cycles that characterize the
industry. The timing, length and volatility of these cycles are difficult to predict. The compound semiconductor industry
has historically been cyclical due to sudden changes in demand, the amount of manufacturing capacity and changes in the
technology employed in compound semiconductors. The rate of changes in demand, including end demand, is high, and the
effect of these changes upon us occurs quickly, exacerbating the volatility of these cycles. These changes have affected the
timing and amounts of customers’ purchases and investments in new technology. These industry cycles create pressure on
our revenue, gross margin and net income.

Our industry has in the past experienced periods of oversupply and that has resulted in significantly reduced prices

for compound semiconductor devices and components, including our products, both as a result of general economic
changes and overcapacity. Oversupply causes greater price competition and can cause our revenue, gross margins and net
income to decline. During periods of weak demand, customers typically reduce purchases, delay delivery of products
and/or cancel orders for our products. Order cancellations, reductions in order size or delays in orders could occur and
would materially adversely affect our business and results of operations. Actions to reduce our costs may be insufficient to
align our structure with prevailing business conditions. We may be required to undertake additional cost-cutting measures,
and may be unable to invest in marketing, research and development and engineering at the levels we believe are necessary
to maintain our competitive position. Our failure to make these investments could seriously harm our business.

A significant portion of our operating expense and manufacturing costs are relatively fixed. If revenue for a 

particular quarter is lower than we expect, we likely will be unable to proportionately reduce our operating expenses or 
fixed manufacturing costs for that quarter, which would harm our operating results.  

If we do not successfully develop new product features and improvements and new products that respond to customer
requirements, our ability to generate revenue, obtain new customers, and retain existing customers may suffer.

Our success depends on our ability to offer new product features, improved performance characteristics and new

products, such as larger diameter substrates, low defect density substrates, thicker or thinner substrates, substrates with
extreme surface flatness specifications, substrates that are manufactured with a doped crystal growth process or substrates
that incorporate leading technology and other technological advances. New products must meet customer

26

Table of Contents

needs and compete effectively on quality, price and performance. The markets for our products are characterized by rapid
technological change, changing customer needs and evolving industry standards. If our competitors introduce products
employing new technologies or performance characteristics, our existing products could become obsolete and
unmarketable. Over time, we have seen our competitors selling more substrates manufactured using a crystal growth
technology similar to ours, which has eroded our technological differentiation.

The development of new product features, improved performance characteristics and new products can be a

highly complex process, and we may experience delays in developing and introducing them. Any significant delay could
cause us to fail to timely introduce and gain market acceptance of new products. Further, the costs involved in researching,
developing and engineering new products could be greater than anticipated. If we fail to offer new products or product
enhancements or fail to achieve higher quality products, we may not generate sufficient revenue to offset our development
costs and other expenses or meet our customers’ requirements.

We have made and may continue to make strategic investments in raw materials suppliers, which may not be successful
and may result in the loss of all or part of our investment.

We have made direct investments or investments through our subsidiaries in raw material suppliers in China, 
which provide us with opportunities to gain supplies of key raw materials that are important to our substrate business. 
These affiliates each have a market beyond that provided by us. We do not have significant influence over every one of 
these companies and in some we have made only a strategic, minority investment. We may not be successful in achieving 
the financial, technological or commercial advantage upon which any given investment is premised, and we could end up 
losing all or part of our investment which would have a negative impact on our results of operations. In the first quarter of 
2017, we incurred an impairment charge of $313,000 against one of our partially-owned suppliers, writing down our 
investment to zero value. Most recently, in the first quarter of 2019, we incurred an impairment charge of $1.1 million for a 
germanium materials company in China in which we have a 25% ownership interest, writing down our investment to zero 
value. The significant decline in the selling prices of raw materials which began in 2015 has weakened some of these 
companies and their losses have negatively impacted our financial results. Further, the increasing concern and restrictions 
in China of hazardous chemicals and other hazardous elements could result in orders to shut down permanently, fines or 
other severe measures.  Any such orders directed at one of our joint venture companies could result in impairment charges 
if the company is forced to close its business, cease operations or incurs fines, or operating losses, which would have a 
material adverse effect on our financial results.

We purchase critical raw materials and parts for our equipment from single or limited sources, and could lose sales if
these sources fail to fill our needs.

We depend on a limited number of suppliers for certain raw materials, components and equipment used in
manufacturing our products, including key materials such as quartz tubing, and polishing solutions. We generally purchase
these materials through standard purchase orders and not pursuant to long-term supply contracts, and no supplier
guarantees supply of raw materials or equipment to us. If we lose any of our key suppliers, our manufacturing efforts could
be significantly hampered and we could be prevented from timely producing and delivering products to our customers.
Prior to investing in our subsidiaries and joint ventures, we sometimes experienced delays obtaining critical raw materials
and spare parts, including gallium, and we could experience such delays again in the future due to shortages of materials or
for other reasons. Delays in receiving equipment or materials could result in higher costs and cause us to delay or reduce
production of our products. If we have to delay or reduce production, we could fail to meet customer delivery schedules
and our revenue and operating results could suffer.

We may not be able to identify or form additional complementary raw material joint ventures.

We might invest in additional joint venture companies in order to remain competitive in our marketplace and

ensure a supply of critical raw materials. However, we may not be able to identify additional complementary joint venture
opportunities or, even once opportunities are identified, we may not be able to reach agreement on the terms of the business
venture with the other investment partners. Further, geopolitical tensions and trade wars could result in government
agencies blocking such new joint ventures. New joint ventures could require cash investments or cause us to

27

Table of Contents

incur additional liabilities or other expenses, any of which could adversely affect our financial condition and operating
results.

The financial condition of our customers may affect their ability to pay amounts owed to us.

Some of our customers may be undercapitalized and cope with cash flow issues. Because of competitive market

conditions, we may grant our customers extended payment terms when selling products to them. Subsequent to our
fulfilling an order, some customers have been unable to make payments when due, reducing our cash balances and causing
us to incur charges to allow for a possibility that some accounts might not be paid. We observed an increase in our accounts
receivable in the first quarter of 2020 and believe this has resulted from work stoppages, shelter-in-place orders and general
cautiousness due to the COVID-19 pandemic. In the past we, have had some customers file for bankruptcy. If our
customers do not pay amounts owed to us then we will incur charges that would reduce our earnings.

We depend on the continuing efforts of our senior management team and other key personnel.  If we lose members of 
our senior management team or other key personnel, or are unable to successfully recruit and train qualified personnel, 
our ability to manufacture and sell our products could be harmed.

Our future success depends on the continuing services of members of our senior management team and other key

personnel.  Our industry is characterized by high demand and intense competition for talent, and the turnover rate can be
high.  We compete for qualified management and other personnel with other specialty material companies and
semiconductor companies.  Our employees could leave our company with little or no prior notice and would be free to
work for a competitor.  If one or more of our senior executives or other key personnel were unable or unwilling to continue
in their present positions, we may not be able to replace them easily or at all, and other senior management may be required
to divert attention from other aspects of the business.  The loss of any of these individuals or our ability to attract or retain
qualified personnel could adversely affect our business.

Our results of operations may suffer if we do not effectively manage our inventory.

We must manage our inventory of raw materials, work in process and finished goods effectively to meet changing

customer requirements, while keeping inventory costs down and improving gross margins. Although we seek to maintain
sufficient inventory levels of certain materials to guard against interruptions in supply and to meet our near term needs, we
may experience shortages of certain key materials. Some of our products and supplies have in the past and may in the
future become obsolete while in inventory due to changing customer specifications, or become excess inventory due to
decreased demand for our products and an inability to sell the inventory within a foreseeable period. This would result in
charges that reduce our gross profit and gross margin. Furthermore, if market prices drop below the prices at which we
value inventory, we would need to take a charge for a reduction in inventory values in accordance with the lower of cost or
net realizable value valuation rule. We have in the past had to take inventory valuation and impairment charges. Any future
unexpected changes in demand or increases in costs of production that cause us to take additional charges for un-saleable,
obsolete or excess inventory, or to reduce inventory values, would adversely affect our results of operations.

The effect of terrorist threats and actions on the general economy could decrease our revenue.

Countries such as the United States and China continue to be on alert for terrorist activity. The potential near and
long-term impact terrorist activities may have in regards to our suppliers, customers and markets for our products and the
economy is uncertain. There may be embargos of ports or products, or destruction of shipments or our facilities, or attacks
that affect our personnel. There may be other potentially adverse effects on our operating results due to significant events
that we cannot foresee. Since we perform all of our manufacturing operations in China, terrorist activity or threats against
U.S.-owned enterprises are a particular concern to us.

III.          Risks Related to International Aspects of Our Business

The Chinese central government is increasingly aware of air pollution and other forms of environmental pollution and
their reform efforts can impact our manufacturing, including intermittent mandatory shutdowns.

The Chinese central government is demonstrating strong leadership to improve air quality and reduce 

environmental pollution.  These efforts have impacted manufacturing companies through mandatory shutdowns, increased 
inspections and regulatory reforms.  In the fourth quarter of 2017, many manufacturing companies in the greater Beijing 
area, including AXT, were instructed by the local government to cease most manufacturing for several days until the air 
quality improved.  In the first quarter of 2018, from February 27 to March 31 over 300 manufacturing companies, 
including AXT, were again intermittently shut down by the local government for a total of ten days, or 30 percent of the 
remaining calendar days, due to severe air pollution.  Our shipments were delayed and our revenue for the quarter was 
negatively impacted.  We expect that mandatory factory shutdowns will occur in the future.  If the frequency of such 
shutdowns increases, especially at the end of a quarter, or if the total number of days of shutdowns prevents us from 
producing enough wafers to ship, then these shutdowns will have a material adverse effect on our manufacturing output, 
revenue and factory utilization.  Each of our raw material supply chain companies could also be impacted by 
environmental related orders from the central government.

Enhanced trade tariffs, import restrictions, export restrictions, Chinese regulations or other trade barriers may
materially harm our business.

All of our wafer substrates are manufactured in China and in the years 2020 and 2019, approximately 10% of our 

revenue was generated by sales to customers in North America, primarily in the U.S.  In September 2018, the Trump 
Administration announced a list of thousands of categories of goods that became subject to tariffs when imported into the 
United States.  This pronouncement imposed tariffs on wafer substrates we imported into the United States. The initial 
tariff rate was 10% and subsequently was increased to 25%. In the years 2020 and 2019 we paid approximately $1.3 
million and $0.7 million, respectively, in tariffs. The future impact of tariffs and trade wars is uncertain. We may be 
required to raise prices, which may result in the loss of customers and our business, financial condition and results of 
operations may be materially harmed.  Additionally, it is possible that our business could be adversely impacted by 
retaliatory trade measures taken by China or other countries in response to existing or future tariffs, which could cause us 
to raise prices or make changes to our operations, which could materially harm our business, financial condition and results 
of operations.

The economic and political conditions between China and the United States, in our view, create an unstable

business environment. The United States government has restricted access by certain Chinese technology companies to
items produced domestically and abroad from U.S. technology and software, which may impact our ability to grow our
revenue. Trade restrictions against China have resulted in a greater determination within China to be self-sufficient and
produce more goods domestically. Government agencies in China may be encouraging and supporting the founding of new
companies, the addition of new products in existing companies and more vertical integration within companies. These
factors have resulted in lower revenue from sales of our wafer substrates in China. Further, the continued threats of tariffs
and other trade restrictions could have a generally disruptive impact on the global economy and, therefore, negatively
impact our sales.

In addition, we may incur increases in costs and other adverse business consequences, including loss of revenue or 

decreased gross margins, due to changes in tariffs, import or export restrictions, further trade barriers, or unexpected 
changes in regulatory requirements.  For example, in July 2012, we received notice of retroactive value-added taxes (VATs) 
levied by the tax authorities in China, which applied for the period from July 1, 2011 to June 30, 2012.  We expensed the 
retroactive VATs of approximately $1.3 million in the quarter ended June 30, 2012, which resulted in a decrease in our 
gross margins.  These VATs will continue to negatively impact our gross margins for the future quarters.  Given the 
relatively fluid regulatory environment in China and the United States, there could be additional tax or other regulatory 
changes in the future. Any such changes could directly and materially adversely impact our financial results and general 
business condition.

29

Table of Contents

The spread of COVID-19 has affected our business operations and financial performance.

The spread of COVID-19 has impacted our operations and financial performance. This outbreak has triggered

references to the SARS outbreak, which occurred in 2003 and affected our business operations. Any severe occurrence of
an outbreak of a contagious disease such as COVID-19, SARS, Avian Flu or Ebola may cause us or the government to
temporarily close our manufacturing operations in China. In January 2020, virtually all companies in China were ordered
to remain closed after the traditional Lunar New Year holiday ended, including our subsidiaries in China. If there is a
renewed surge of the COVID-19 pandemic in China, the Chinese government may require companies to close again.  If
one or more of our key suppliers is required to close for an extended period, we might not have enough raw material
inventories to continue manufacturing operations. In addition, travel restrictions between China and the U.S. have
disrupted our normal movement to and from China and this has impacted our efficiency. The outbreak has affected
transportation and reduced the availability of air transport, caused port closures, and increased border controls and closures.
If our manufacturing operations were closed for a significant period or we experience difficulty in shipping our products,
we could lose revenue and market share, which would depress our financial performance and could be difficult to
recapture. If one of our key customers is required to close for an extended period this may delay the placement of new
orders. As a result, our revenue would decline. Further, customers might default on their obligations to us. In the first
quarter of 2020 we observed an increase in our accounts receivable and believe this is the result of businesses slowing
down and a general cautiousness due to the COVID-19 pandemic. Such events would negatively impact our financial
performance.

 Financial market volatility and adverse changes in the domestic, global, political and economic environment could 
have a significant adverse impact on our business, financial condition and operating results.

We are subject to the risks arising from adverse changes and uncertainty in domestic and global economies.

Uncertain global economic and political conditions or low or negative growth in China, Europe or the United States, along
with volatility in the financial markets, increasing national debt and fiscal concerns in various regions and the adoption and
availability of fiscal and monetary stimulus measures to counteract the impact of the COVID-19 pandemic, pose challenges
to our industry. Currently China’s economy is slowing and this could impact our financial performance. In addition, tariffs,
trade restrictions, trade wars and Brexit are creating an unstable environment and can disrupt or restrict commerce.
Although we remain well-capitalized, the cost and availability of funds may be adversely affected by illiquid credit
markets. Volatility in U.S. and international markets and economies may adversely affect our liquidity, financial condition
and profitability. Another severe or prolonged economic downturn could result in a variety of risks to our business,
including:

● increased volatility in our stock price;

● increased volatility in foreign currency exchange rates;

● delays in, or curtailment of, purchasing decisions by our customers or potential customers;

● increased credit risk associated with our customers or potential customers, particularly those that may operate

in industries most affected by the economic downturn; and

● impairment of our tangible or intangible assets.

In the past, most recently in the fourth quarter of 2018 and continuing in 2019, we experienced delays in customer

purchasing decisions and disruptions in a normal volume of customer orders that we believe were in part due to the
uncertainties in the global economy, resulting in an adverse impact on consumer spending. During challenging and
uncertain economic times and in tight credit markets, many customers delay or reduce technology purchases. Should
similar events occur again, our business and operating results could be significantly and adversely affected.

30

Table of Contents

We derive a significant portion of our revenue from international sales, and our ability to sustain and increase our
international sales involves significant risks.

Approximately 90% of our revenue is from international sales. We expect that sales to customers outside the

United States, particularly sales to customers in Japan, Taiwan, Europe and China, will continue to represent a significant
portion of our revenue. Therefore, our revenue growth depends significantly on the expansion of our international sales and
operations.

All of our manufacturing facilities and most of our suppliers are also located outside the United States. Managing
our overseas operations presents challenges, including periodic regional economic downturns, trade balance issues, threats
of trade wars, varying business conditions and demands, political instability, variations in enforcement of intellectual
property and contract rights in different jurisdictions, differences in the ability to develop relationships with suppliers and
other local businesses, changes in U.S. and international laws and regulations, including U.S. export restrictions,
fluctuations in interest and currency exchange rates, the ability to provide sufficient levels of technical support in different
locations, cultural differences and perceptions of U.S. companies, shipping delays and terrorist acts or acts of war, natural
disasters and epidemics or pandemics, such as COVID-19, among other risks. Many of these challenges are present in
China, which represents a large potential market for semiconductor devices. Global uncertainties with respect to: (i)
economic growth rates in various countries; (ii) sustainability of demand for electronic products; (iii) capital spending by
semiconductor manufacturers; (iv) price weakness for certain semiconductor devices; (v) changing and tightening
environmental regulations; (vi) political instability in regions where we have operations and (vii) trade wars may also affect
our business, financial condition and results of operations.

Our dependence on international sales involves a number of risks, including:

● changes in tariffs, import restrictions, export restrictions, or other trade barriers;

● unexpected changes in regulatory requirements;

● longer periods to collect accounts receivable;

● foreign exchange rate fluctuations;

● changes in export license requirements;

● political and economic instability; and

● unexpected changes in diplomatic and trade relationships.

Most of our sales are denominated in U.S. dollars, except for sales to our Chinese customers which are
denominated in renminbi and our Japanese customers which are denominated in Japanese yen. We also have some small
sales denominated in Euro. Increases in the value of the U.S. dollar could increase the price of our products in non-U.S.
markets and make our products more expensive than competitors’ products in these markets.

We are subject to foreign exchange gains and losses that materially impact our income statement.

We are subject to foreign exchange gains and losses that materially impact our statement of operations.  For 

example, in 2020 we incurred a loss of $411,000.

The functional currency of our companies in China is the Chinese renminbi, the local currency. We can incur 
foreign exchange gains or losses when we pay dollars to one of our China-based companies or a third-party supplier in 
China.  Similarly, if a company in China pays renminbi into one of our bank accounts transacting in dollars the renminbi 
will be converted to dollars and we can incur a foreign exchange gain or loss.  Hedging renminbi will be considered in 

31

Table of Contents

the future but it is complicated by the number of companies involved, the diversity of transactions and restrictions imposed 
by the banking system in China.  

Sales to Japanese customers are denominated in Japanese yen.  This subjects us to fluctuations in the exchange 

rates between the U.S. dollar and the Japanese yen and can result in foreign exchange gains and losses. This has been 
problematic in the past and, therefore, we instituted a foreign currency hedging program dealing with yen which has 
mitigated the problem.  

Joint venture raw material companies in China bring certain risks.

Since our consolidated subsidiaries and all of our joint venture raw material companies reside in China, their

activities could subject us to a number of risks associated with conducting operations internationally, including:

● unexpected changes in regulatory requirements that may limit our ability to manufacture, export the products

of these companies or sell into particular jurisdictions or impose multiple conflicting tax laws and
regulations;

● the imposition of tariffs, trade barriers and duties;

● difficulties in managing geographically disparate operations;

● difficulties in enforcing agreements through non-U.S. legal systems;

● political and economic instability, civil unrest or war;

● terrorist activities that impact international commerce;

● difficulties in protecting our intellectual property rights, particularly in countries where the laws and practices

do not protect proprietary rights to as great an extent as do the laws and practices of the United States;

● changing laws and policies affecting economic liberalization, foreign investment, currency convertibility or

exchange rates, taxation or employment; and

● nationalization of foreign-owned assets, including intellectual property.

Uncertainty regarding the United States’ foreign policy, particularly with regards to China, could disrupt our business.

We manufacture our substrates in China and, in 2020, approximately 90% of our sales were to customers located 

outside the United States. Further, we have partial ownership of raw material companies in China as part of our supply 
chain.  The United States’ current foreign policy has created uncertainty and caution in the international business 
community, resulting in disruptions in manufacturing, import/export, trade tariffs, sales, investments and other business 
activity.  Such disruptions have had an adverse impact on our financial performance and could continue in the future. 

If China places restrictions on freight and transportation routes and on ports of entry and departure this could result in
shipping delays or increased costs for shipping.

In August 2015, there was an explosion at the Port of Tianjin, China.  As a result of this incident the government 
placed restrictions on importing certain materials and on freight routes used to transport these materials.  We experienced 
some modest disruption from these restrictions.  If the government were to place additional restrictions on the 
transportation of materials, then our ability to transport our raw materials or products could be limited and result in 
manufacturing delays or bottlenecks at shipping ports, affecting our ability to deliver products to our customers. During 

32

Table of Contents

periods of such restrictions, we may increase our stock of critical materials (such as arsenic, gallium and other items) for 
use during the period that these restrictions are likely to last, which will increase our use of cash and increase our inventory 
level. Any of these restrictions could materially and adversely impact our results of operations and our financial condition.

Our operating results depend in large part on continued customer acceptance of our substrate products manufactured
in China and continued improvements in product quality.

We manufacture all of our products in China, and source most of our raw materials in China. We have in the past

experienced quality problems with our China-manufactured products. Our previous quality problems caused us to lose
market share to our competitors, as some of our customers reduced their orders until our wafer surface quality was as good
and as consistent as that offered by our competitors and instead allocated their requirements for compound semiconductor
substrates to our competitors. If we are unable to continue to achieve customer qualifications for our products, or if we are
unable to control product quality, customers may not increase purchases of our products, our China facilities will become
underutilized, and we will be unable to achieve revenue growth.

Changes in China’s political, social, regulatory or economic environments may affect our financial performance.

Our financial performance may be affected by changes in China’s political, social, regulatory or economic

environments. The role of the Chinese central and local governments in the Chinese economy is significant. The Beijing
municipal government’s decision to move to the Tongzhou district, the original location of our manufacturing company,
resulted in the city instructing virtually all existing manufacturing companies, including AXT, to relocate all or some of
their manufacturing lines. We were instructed to move our gallium arsenide manufacturing line out of the area. Chinese 
policies toward hazardous materials, including arsenic, environmental controls, air pollution, economic liberalization, laws 
and policies affecting technology companies, foreign investment, currency exchange rates, taxation structure and other 
matters could change, resulting in greater restrictions on our ability to do business and operate our manufacturing facilities 
in China. We have observed a growing fluidity and tightening of regulations concerning hazardous materials, other 
environmental controls and air pollution.  The Chinese government could revoke, terminate or suspend our operating 
licenses for reasons related to environmental control over the use of hazardous materials, air pollution, labor complaints, 
national security and similar reasons without compensation to us. Further, the central government encourages employees to
report to the appropriate regulatory agencies possible safety or environmental violations, but there may not be actual
violations. In days of severe air pollution the government has ordered manufacturing companies to stop all production.  For 
example, in the first quarter of 2018, from February 27 to March 31, over 300 manufacturing companies, including us, 
were again intermittently shut down by the local government for a total of ten days due to severe air pollution.  Our 
shipments were delayed and our revenue for the quarter was negatively impacted. We expect that mandatory factory
shutdowns will occur in the future. Any failure on our part to comply with governmental regulations could result in the loss 
of our ability to manufacture our products.  Further, any imposition of surcharges or any increase in Chinese tax rates or 
reduction or elimination of Chinese tax benefits could hurt our financial results.

Our international operations are exposed to potential adverse tax consequence in China.

Our international operations create a risk of potential adverse tax consequences.  Taxes on income in our China-

based companies are dependent upon acceptance of our operational practices and intercompany transfer pricing by local tax 
authorities as being on an arm's length basis. Due to inconsistencies among taxing authorities in application of the arm's 
length standard, transfer pricing challenges by tax authorities could, if successful, materially increase our consolidated 
income tax expense. We are subject to tax audits in China and an audit could result in the assessment of additional income 
tax against us.  This could have a material adverse effect on our operating results or cash flows in the period or periods for 
which that determination is made and could result in increases to our overall tax expense in subsequent periods.  Various 
taxing agencies in China are increasingly focused on tax reform and other legislative action to increase tax revenue. In 
addition to risks regarding income tax we have in the past been retroactively assessed value added taxes (“VAT” or sales 
tax) and such VAT assessments could occur again in the future.

33

Table of Contents

If there are power shortages in China, we may have to temporarily close our China operations, which would adversely
impact our ability to manufacture our products and meet customer orders, and would result in reduced revenue.

In the past, China has faced power shortages resulting in power demand outstripping supply in peak periods.
Instability in electrical supply has caused sporadic outages among residential and commercial consumers causing the
Chinese government to implement tough measures to ease the energy shortage. If further problems with power shortages
occur in the future, we may be required to make temporary closures of our operations or of our subsidiary and joint venture
raw material companies. We may be unable to manufacture our products and would then be unable to meet customer orders
except from finished goods inventory on hand. As a result, our revenue could be adversely impacted, and our relationships
with our customers could suffer, impacting our ability to generate future revenue. In addition, if power is shut off at any of
our facilities at any time, either voluntarily or as a result of unplanned brownouts, during certain phases of our
manufacturing process including our crystal growth phase, the work in process may be ruined and rendered unusable,
causing us to incur costs that will not be covered by revenue, and negatively impacting our cost of revenue and gross
margins.

VI.         Risks Related to Our Financial Results and Capital Structure

We may utilize our cash balances for relocating manufacturing lines, adding capacity, acquiring state-of-the-art
equipment or offsetting a business downturn resulting in the decline of our existing cash and if we need additional
capital, funds may not be available on acceptable terms, or at all.

Our liquidity is affected by many factors including among others, the relocation of our gallium arsenide
manufacturing lines, the expansion of our capacity to meet market demand, the acquisition of state-of-the-art equipment,
other capital expenditures, operating activities, the effect of exchange rate changes and other factors related to the
uncertainties of the industry and global economies. Such matters could draw down our cash reserves, which could
adversely affect our financial condition, require us to incur debt, reduce our value and possibly impinge our ability to raise
debt and equity funding in the future, at a time when we might need to raise additional cash or elect to raise additional
cash. Accordingly, there can be no assurance that events will not require us to seek additional capital or, if required, that
such capital would be available on terms acceptable to us, if at all.

The terms of the private equity raised in China as a first step toward an IPO on the STAR Market grant each Investor a
right of redemption if Tongmei fails to achieve its IPO.

Pursuant to the Capital Investment Agreements with the Investors, each Investor has the right to require AXT to 

redeem any or all Tongmei shares held by such Investor at the original purchase price paid by such Investor, without 
interest, in the event of a material adverse change or if Tongmei does not achieve its IPO on or before December 31, 2022. 
This right is suspended when Tongmei submits its formal application to the CSRC.  Tongmei currently plans to submit its 
formal application to the CSRC in the third quarter of 2021.  However, if on December 31, 2022 the IPO application has 
been submitted and accepted by the CSRC or the stock exchange and such submission remains under review, then the date 
when such investor is entitled to exercise such redemption right shall be deferred to a date when such submission is 
rejected by the CSRC or stock exchange, or the date when Tongmei withdraws its IPO application. The process of going 
public on the STAR Market includes several periods of review and is therefore a lengthy process. Tongmei does not expect 
to complete the IPO until mid-2022. The listing of Tongmei on China’s STAR Market will not change the status of AXT as 
a U.S. public company.  There can be no assurances that Tongmei will complete its IPO by December 31, 2022 or at all. In 
the event that investors exercise their redemption rights, we may be required to seek additional capital in order to redeem 
their Tongmei shares and there would be no assurances that such capital would be available on terms acceptable to us, if at 
all. Any redemptions could have a material adverse effect on our business, financial condition and results of operations.

34

Unpredictable fluctuations in our operating results could disappoint analysts or our investors, which could cause our
stock price to decline.

We have experienced, and may continue to experience, significant fluctuations in our revenue, gross margins and

earnings. Our quarterly and annual revenue and operating results have varied significantly in the past and may vary
significantly in the future due to a number of factors, including:

● our ability to develop, manufacture and deliver high quality products in a timely and cost-effective manner;

● unforeseen disruptions at our new sites;

● disruptions in manufacturing if air pollution, or other environmental hazards, or outbreaks of contagious

diseases causes the Chinese government to order work stoppages;

● fluctuation of our manufacturing yields;

● decreases in the prices of our or our competitors’ products;

● fluctuations in demand for our products;

● the volume and timing of orders from our customers, and cancellations, push-outs and delays of customer

orders once booked;

● decline in general economic conditions or downturns in the industry in which we compete;

● expansion of our manufacturing capacity;

● expansion of our operations in China;

● limited availability and increased cost of raw materials;

● costs incurred in connection with any future acquisitions of businesses or technologies; and

● increases in our expenses, including expenses for research and development.

Due to these factors, we believe that period-to-period comparisons of our operating results may not be meaningful

indicators of our future performance.

A substantial percentage of our operating expenses are fixed, and we may be unable to adjust spending to
compensate for an unexpected shortfall in revenue. As a result, any delay in generating revenue could cause our operating
results to fall below the expectations of market analysts or investors, which could also cause our stock price to decline.

If our operating results and financial performance do not meet the guidance that we have provided to the public, our
stock price may decline.

We provide public guidance on our expected operating and financial results.  Although we believe that this 

guidance provides our stockholders, investors and analysts with a better understanding of our expectations for the future, 
such guidance is comprised of forward-looking statements subject to the risks and uncertainties described in this report and 
in our other public filings and public statements.  Our actual results may not meet the guidance we have provided.  If our 
operating or financial results do not meet our guidance or the expectations of investment analysts, our stock price may 
decline.

We have adopted certain anti-takeover measures that may make it more difficult for a third party to acquire us.

Our board of directors has the authority to issue up to 800,000 shares of preferred stock in addition to the
outstanding shares of Series A preferred stock and to determine the price, rights, preferences and privileges of those shares
without any further vote or action by the stockholders. The rights of the holders of common stock will be subject to, and
may be adversely affected by, the rights of the holders of any preferred stock that may be issued in the future. The issuance
of shares of preferred stock could have the effect of making it more difficult for a third party to acquire a majority of our
outstanding voting stock. We have no present intention to issue additional shares of preferred stock.

Provisions in our restated certificate of incorporation and amended and restated bylaws may have the effect of

delaying or preventing a merger, acquisition or change of control, or changes in our management, which could adversely
affect the market price of our common stock. The following are some examples of these provisions:

● the division of our board of directors into three separate classes, each with three-year terms;

● the right of our board to elect a director to fill a space created by a board vacancy or the expansion of the

board;

● the ability of our board to alter our amended and restated bylaws; and

● the requirement that only our board or the holders of at least 10% of our outstanding shares may call a special

meeting of our stockholders.

Furthermore, because we are incorporated in Delaware, we are subject to the provisions of Section 203 of the
Delaware General Corporation Law. These provisions prohibit us from engaging in any business combination with any
interested stockholder (a stockholder who owns 15% or more of our outstanding voting stock) for a period of three years
following the time that such stockholder became an interested stockholder, unless:

● 662/3% of the shares of voting stock not owned by the interested stockholder approve the merger or

combination, or

● the board of directors approves the merger or combination or the transaction which resulted in the

stockholder becoming an interested stockholder.

Our common stock may be delisted from The Nasdaq Global Select Market, which could negatively impact the price of
our common stock and our ability to access the capital markets.

Our common stock is listed on The Nasdaq Global Select Market. The bid price of our common stock has in the
past closed below the $1.00 minimum per share bid price required for continued inclusion on The Nasdaq Global Select
Market under Marketplace Rule 5450(a). If the bid price of our common stock remains below $1.00 per share for thirty
consecutive business days, we could be subject to delisting from the Nasdaq Global Select Market.

Any delisting from The Nasdaq Global Select Market could have an adverse effect on our business and on the

trading of our common stock. If a delisting of our common stock were to occur, our common stock would trade in the over-
the-counter market and be quoted on a service such as those provided by OTC Markets Group, Inc. Such alternatives are
generally considered to be less efficient markets, and our stock price, as well as the liquidity of our common stock, may be
adversely impacted as a result. Delisting from The Nasdaq Global Select Market could also have other negative results,
including the potential loss of confidence by customers, suppliers and employees, the loss of institutional investor interest
and fewer business development opportunities, as well as the loss of liquidity for our stockholders.

Our ability to use our net operating loss carryforwards and certain other tax attributes may be limited.

As of December 31, 2020, we had U.S. federal net operating loss carryforwards of approximately $57.0 million.

We have utilized all state net operating losses, primarily in the state of California, as of December 31, 2020. Under
Sections 382 and 383 of the Internal Revenue Code of 1986, as amended, if a corporation undergoes an “ownership
change,” the corporation’s ability to use its pre-change net operating loss carryforwards and other pre-change tax attributes,
such as research tax credits, to offset its post-change income and taxes may be limited.  In general, an “ownership change”
occurs if there is a cumulative change in our ownership by “5% shareholders” that exceeds 50 percentage points over a
rolling three-year period.  Similar rules may apply under state tax laws.  We might have undergone prior ownership
changes, and we may undergo ownership changes in the future, which may result in limitations on our net operating loss
carryforwards and other tax attributes.  Any such limitations on our ability to use our net operating loss carryforwards and
other tax attributes could adversely impact our business, financial condition and results of operations.

V.         Risks Related to Our Intellectual Property

Intellectual property infringement claims may be costly to resolve and could divert management attention.

Other companies may hold or obtain patents on inventions or may otherwise claim proprietary rights to
technology necessary to our business. The markets in which we compete are comprised of competitors that in some cases
hold substantial patent portfolios covering aspects of products that could be similar to ours. We could become subject to
claims that we are infringing patent, trademark, copyright or other proprietary rights of others. We may incur expenses to
defend ourselves against such claims or enter into cross license agreements that require us to pay royalty payments to
resolve such claims. For example, in 2020, we and a competitor entered into the Cross License Agreement, which has a
term that began on January 1, 2020 and expires on December 31, 2029. We have in the past been involved in lawsuits
alleging patent infringement, and could in the future be involved in similar litigation.

If we are unable to protect our intellectual property, including our non-patented proprietary process technology, we may
lose valuable assets or incur costly litigation.

We rely on a combination of patents, copyrights, trademarks, trade secrets and trade secret laws, non-disclosure 
agreements and other intellectual property protection methods to protect our proprietary technology. We believe that our 
internal, non-patented proprietary process technology methods, systems and processes are a valuable and critical element 
of our intellectual property. We must establish and maintain safeguards to avoid the theft of these processes. Our ability to 
establish and maintain a position of technology leadership also depends on the skills of our development personnel.  
Despite our efforts to protect our intellectual property, third parties can develop products or processes similar to ours. Our 
means of protecting our proprietary rights may not be adequate, and our competitors may independently develop similar 
technology, duplicate our products or design around our patents. We believe that at least two of our competitors ship GaAs 
substrates produced using a process similar to our VGF process. Our competitors may also develop and patent 
improvements to the VGF technology upon which we rely, and thus may limit any exclusivity we enjoy by virtue of our 
patents or trade secrets.

It is possible that pending or future United States or foreign patent applications made by us will not be approved,
that our issued patents will not protect our intellectual property, or that third parties will challenge our ownership rights or
the validity of our patents. In addition, the laws of some foreign countries may not protect our proprietary rights to as great
an extent as do the laws of the United States and it may be more difficult to monitor the use of our intellectual property.
Our competitors may be able to legitimately ascertain non-patented proprietary technology embedded in our systems. If
this occurs, we may not be able to prevent the development of technology substantially similar to ours.

We may have to resort to costly litigation to enforce our intellectual property rights, to protect our trade secrets or

know-how or to determine their scope, validity or enforceability. Enforcing or defending our proprietary technology is
expensive, could cause us to divert resources and may not prove successful. Our protective measures may prove inadequate
to protect our proprietary rights, and if we fail to enforce or protect our rights, we could lose valuable assets.

VI.           Risks Related to Compliance, Environmental Regulations and Other Legal Matters

If we, or any of our partially-owned supply chain companies, fail to comply with environmental and safety regulations,
we may be subject to significant fines or forced to cease our operations.

We are subject to federal, state and local environmental and safety laws and regulations in all of our operating

locations, including laws and regulations of China, such as laws and regulations related to the development, manufacture
and use of our products, the use of hazardous materials, the operation of our facilities, and the use of our real property.
These laws and regulations govern the use, storage, discharge and disposal of hazardous materials during manufacturing,
research and development, and sales demonstrations. If we, or any of our partially-owned supply chain companies, fail to
comply with applicable regulations, we could be subject to substantial liability for clean-up efforts, personal injury, fines or
suspension or be forced to close or temporarily cease our operations, and/or suspend or terminate the development,
manufacture or use of certain of our products, the use of our facilities, or the use of our real property, each of which could
have a material adverse effect on our business, financial condition and results of operations.

The Chinese central government is demonstrating strong leadership to improve air quality and reduce 
environmental pollution. The central government encourages employees to report to the appropriate regulatory agencies 
possible safety or environmental violations but there may not be actual violations. These efforts have impacted 
manufacturing companies through mandatory shutdowns, increased inspections and regulatory reforms. In the first quarter 
of 2018, from February 27 to March 31 over 300 manufacturing companies were again intermittently shut down by the 
local government for a total of ten days, or 30 percent of the remaining calendar days, due to severe air pollution.  Our 
shipments were delayed and our revenue for the quarter was negatively impacted.  We expect that mandatory factory 
shutdowns will occur in the future.  If the frequency of such shutdowns increases, especially at the end of a quarter, or if 
the total number of days of shutdowns prevents us from producing enough wafers to ship, then the shutdowns will have a 
material adverse effect on our manufacturing output, revenue and factory utilization.  We believe the relocation of our 
gallium arsenide and germanium manufacturing lines mitigates our exposure to factory shutdowns. Each of our raw 
material supply chain companies could also be impacted by environmental related orders from the central government. 

In addition, from time to time, the Chinese government issues new regulations, which may require additional 

actions on our part to comply. For example on February 27, 2015, the China State Administration of Work Safety updated 
its list of hazardous substances.  The previous list, which was published in 2002, did not restrict the materials that we use in 
our wafers.  The new list added gallium arsenide.  As a result of the newly published list, we were required to seek 
additional permits.

We could be subject to suits for personal injuries caused by hazardous materials.

In 2005, a complaint was filed against us alleging personal injury, general negligence, intentional tort, wage loss
and other damages, including punitive damages, as a result of exposure of plaintiffs to high levels of gallium arsenide in
gallium arsenide wafers, and methanol. Other current and/or former employees could bring litigation against us in the
future. Although we have in place engineering, administrative and personnel protective equipment programs to address
these issues, our ability to expand or continue to operate our present locations could be restricted or we could be required to
acquire costly remediation equipment or incur other significant expenses if we were found liable for failure to comply with
environmental and safety regulations. Existing or future changes in laws or regulations in the United States and China may
require us to incur significant expenditures or liabilities, or may restrict our operations. In addition, our employees could be
exposed to chemicals or other hazardous materials at our facilities and we may be subject to lawsuits seeking damages for
wrongful death or personal injuries allegedly caused by exposure to chemicals or hazardous materials at our facilities.

Litigation is inherently uncertain and while we would expect to defend ourselves vigorously, it is possible that our

business, financial condition, results of operations or cash flows could be affected in any particular period by litigation
pending and any additional litigation brought against us. In addition, future litigation could divert management’s attention
from our business and operations, causing our business and financial results to suffer. We could

38

Table of Contents

incur defense or settlement costs in excess of the insurance covering these litigation matters, or that could result in
significant judgments against us or cause us to incur costly settlements, in excess of our insurance limits.

We are subject to internal control evaluations and attestation requirements of Section 404 of the Sarbanes-Oxley Act.

Pursuant to Section 404 of the Sarbanes-Oxley Act of 2002, we must include in our Annual Report on Form 10-K
a report of management on the effectiveness of our internal control over financial reporting. Ongoing compliance with this
requirement is complex, costly and time-consuming and it extends to our companies in China. If: (1) we fail to maintain
effective internal control over financial reporting; or (2) our management does not timely assess the adequacy of such
internal control, we could be subject to regulatory sanctions and the public’s perception of us may be adversely impacted.

We need to continue to improve or implement our systems, procedures and controls.

We rely on certain manual processes for data collection and information processing, as do our joint venture raw
material companies. If we fail to manage these procedures properly or fail to effectively manage a transition from manual
processes to automated processes, our systems and controls may be disrupted. To manage our business effectively, we may
need to implement additional management information systems, further develop our operating, administrative, financial
and accounting systems and controls, add experienced senior level managers, and maintain close coordination among our
executive, engineering, accounting, marketing, sales and operations organizations.

Our common stock has been trading publicly on the NASDAQ Global Market (NASDAQ) under the symbol

“AXTI” since May 20, 1998, the date we consummated our initial public offering, and beginning on January 3, 2011, our 
common stock began trading on the NASDAQ Global Select Market under the same symbol.  The following table sets 
forth the range of high and low sales prices of the common stock for the periods indicated, as reported by NASDAQ.

As of March 4, 2021, there were 170 holders of record of our common stock. Because many shares of AXT’s
common stock are held by brokers and other institutions on behalf of stockholders, we are unable to estimate the total
number of beneficial owners of our common stock.

We have never paid or declared any cash dividends on our common stock and do not anticipate paying cash

dividends in the foreseeable future. Dividends accrue on our outstanding Series A preferred stock at the rate of $0.20 per
annum per share of Series A preferred stock. The 883,000 shares of Series A preferred stock issued and outstanding as of
December 31, 2020 are valued at $3,532,000 and are non-voting and non-convertible preferred stock with a 5.0%
cumulative annual dividend rate payable when declared by our board of directors, and a $4.00 per share liquidation
preference over common stock that must be paid before any distribution is made to the holders of our common stock.
These shares of preferred stock were issued to shareholders of Lyte Optronics, Inc. in connection with the completion of
our acquisition of Lyte Optronics, Inc. on May 28, 1999. By the terms of the Series A preferred stock, so long as any shares
of Series A preferred stock are outstanding, neither the Company nor any subsidiary of the Company shall redeem,
repurchase or otherwise acquire any shares of common stock, unless all accrued dividends on the Series A preferred stock
have been paid. During 2013 and 2015, we repurchased shares of our outstanding common stock.  As of December 31,
2015, the Series A preferred stock had cumulative dividends of $2.9 million and we include such cumulative dividends in
“Accrued liabilities” in our consolidated balance sheets. No shares were repurchased during 2020, 2019 and 2018 under
this program. If we are required to pay the cumulative dividends on the Series A preferred stock, our cash and cash
equivalents would be reduced.  We account for the cumulative year to date dividends on the Series A preferred stock when
calculating our earnings per share.

Issuer Purchases of Equity Securities

On October 27, 2014, our Board of Directors approved a stock repurchase program pursuant to which we may

repurchase up to $5.0 million of our outstanding common stock.  These repurchases can be made from time to time in the
open market and are funded from our existing cash balances and cash generated from operations. During 2015, we
repurchased approximately 908,000 shares at an average price of $2.52 per share for a total purchase price
of approximately $2.3 million under the stock repurchase program. No shares were repurchased during 2020 or 2019 under
this program. As of December 31, 2020 and 2019, approximately $2.7 million remained available for future repurchases
under this program, respectively.

Item 7.  Management’s Discussion and Analysis of Financial Condition and Results of Operations

In addition to historical information, the following discussion contains forward-looking statements that are subject

to risks and uncertainties. Actual results may differ substantially from those referred to herein due to a number of factors,
including but not limited to risks described in the section entitled Item 1A. “Risk Factors” and elsewhere in this Annual
Report on Form 10-K. This discussion should be read in conjunction with Item 6. “Selected Consolidated Financial Data”
and our consolidated financial statements and related notes included elsewhere in this Form 10-K.

Critical Accounting Policies and Estimates

We prepare our consolidated financial statements in accordance with accounting principles generally accepted in
the United States of America (“U.S. GAAP”). Accordingly, we make estimates, assumptions and judgments that affect the
amounts reported on our consolidated financial statements. These estimates, assumptions and judgments about future
events and their effects on our results cannot be determined with certainty, and are made based upon our historical
experience and on other assumptions that are believed to be reasonable under the circumstances. These estimates may
change as new events occur or additional information is obtained, and we may periodically be faced with uncertainties, the
outcomes of which are not within our control and may not be known for a prolonged period of time.

We have identified the policies below as critical to our business operations and understanding of our financial

condition and results of operations. Critical accounting policies are material to the presentation of our consolidated
financial statements and require us to make difficult, subjective or complex judgments that could have a material effect on
our financial condition and results of operations. They may require us to make assumptions about matters that are highly
uncertain at the time of the estimate. Different estimates that we could have used, or changes in the estimate that are
reasonably likely to occur, may have a material impact on our financial condition or results of operations. We also refer you
to Note 1 to our consolidated financial statements included elsewhere in this Form 10-K.

Revenue Recognition and Sales Returns

We manufacture and sell high-performance compound semiconductor substrates including indium phosphide,

gallium arsenide and germanium wafers, and our consolidated subsidiaries sell certain raw materials, including high purity
gallium (6N and 7N Ga), pyrolytic boron nitride (pBN) crucibles and boron oxide (B2O3). After we ship our products,
there are no remaining obligations or customer acceptance requirements that would preclude revenue recognition. Our
products are typically sold pursuant to purchase orders placed by our customers, and our terms and conditions of sale do
not require customer acceptance. We account for a contract with a customer when there is a legally enforceable contract,
which could be the customer’s purchase order, the rights of the parties are identified, the contract has commercial terms,
and collectibility of the contract consideration is probable. The majority of our contracts have a single performance
obligation to transfer products and are short term in nature, usually less than six months. Our revenue is measured based on
the consideration specified in the contract with each customer in exchange for transferring products that are generally
based upon a negotiated, formula, list or fixed price. Revenue is recognized when control of the promised goods is
transferred to our customer, which is either upon shipment from our dock, receipt at the customer’s dock, or removal from
consignment inventory at the customer’s location, in an amount that reflects the consideration we expect to be entitled to
receive in exchange for those goods.

We have elected to account for shipping and handling as activities to fulfill the promise to transfer the goods. As
such, shipping and handling fees billed to customers in a sales transaction are recorded in revenue. Shipping and handling
costs incurred are recorded in cost of revenue. Sales taxes and value added taxes in foreign jurisdictions that are collected
from customers and remitted to governmental authorities are accounted for on a net basis and, therefore, are excluded from
revenue.

We do not provide training, installation or commissioning services. We accrue for future returns based on

historical data, prior experience, current economic trends and changes in customer demand at the time revenue is
recognized. We do not recognize any asset associated with the incremental cost of obtaining revenue generating customer
contracts. As such, sales commissions and other related expenses are expensed as incurred, given that the expected period
of benefit is less than one year.

Accounts Receivable and Allowance for Doubtful Accounts

Accounts receivable are recorded at the invoiced amount and are not interest bearing. We review at least quarterly,

or when there are changes in credit risks, the likelihood of collection on our accounts receivable balances and provide an
allowance for doubtful accounts receivable for any expected credit losses primarily based upon the age of these accounts.
We evaluate receivables from U.S. customers with an emphasis on balances in excess of 90 days and for receivables from
customers located outside the U.S. with an emphasis on balances in excess of 120 days and establish a reserve allowance
on the receivable balances if needed. The reason for the difference in the evaluation of receivables between foreign and
U.S. customers is that U.S. customers have historically made payments in a shorter period of time than foreign customers.
Foreign business practices generally require us to allow customer payment terms that are longer than those accepted in the
United States. We assess the probability of collection based on a number of factors, including the length of time a
receivable balance has been outstanding, our past history with the customer and their credit-worthiness.

We exercise judgment when determining the adequacy of our reserves as we evaluate historical bad debt trends,

general economic conditions in the United States and internationally, and changes in customer financial conditions.
Uncollectible receivables are recorded as bad debt expense when a credit loss is expected through the establishment of an
allowance, which would then be written off when all efforts to collect have been exhausted and recoveries are recognized
when they are received. As of December 31, 2020 and 2019, our accounts receivable, net balance was $24.6 million and
$19.0 million, respectively, which was net of an allowance for doubtful accounts of $217,000 and $34,000 as of December
31, 2020 and 2019, respectively. During 2020, we increased the allowance for doubtful accounts by $183,000 due to the
poor financial condition of a few customers. During 2019, the allowance for doubtful accounts decreased by $324,000
primarily due to the deconsolidation of Beijing JiYa Semiconductor Material Co., Ltd. (“JiYa”) as of March 11, 2019. If
actual uncollectible accounts differ substantially from our estimates, revisions to the estimated allowance for doubtful
accounts would be required, which could have a material impact on our financial results for the future periods.

Warranty Reserve

We maintain a warranty reserve based upon our claims experience during the prior twelve months and any

pending claims and returns of which we are aware. Warranty costs are accrued at the time revenue is recognized. As of
December 31, 2020 and 2019, accrued product warranties totaled $609,000 and $387,000, respectively. The increase in
accrued product warranties is primarily attributable to four customers who claimed certain wafers did not meet their
specifications. If actual warranty costs or pending new claims differ substantially from our estimates, revisions to the
estimated warranty liability would be required, which could have a material impact on our financial condition and results
of operations for future periods.

Inventory Valuation

Inventories are stated at the lower of cost (approximated by standard cost) or net realizable value. Cost is
determined using the weighted average cost method. Our inventory consists of raw materials as well as finished goods and
work-in-process that include material, labor and manufacturing overhead costs. We routinely evaluate the levels of our
inventory in light of current market conditions in order to identify excess and obsolete inventory, and we provide a reserve
for certain inventories based upon the age and quality of the product and the projections for sale of the completed products.
As of December 31, 2020 and 2019, we had an inventory reserve of $17.7 million and $16.4 million, respectively, for
excess and obsolete inventory and $162,000 and $91,000, respectively, for lower of cost or net realizable value reserves. If
actual demand for our products were to be substantially lower than estimated, additional inventory adjustments for excess
or obsolete inventory might be required, which could have a material impact on our business, financial condition and
results of operations.

Impairment of Investments

We classify marketable investments in debt securities as available-for-sale debt securities in accordance with ASC

Topic 320, Investments—Debt Securities. All available-for-sale debt securities with a quoted market value below

45

Table of Contents

cost (or adjusted cost) are reviewed in order to determine whether the decline is other-than-temporary. Factors considered
in determining whether a loss is temporary include the magnitude of the decline in market value, the length of time the
market value has been below cost (or adjusted cost), credit quality, and our ability and intent to hold the debt securities for
a period of time sufficient to allow for any anticipated recovery in market value. We also review our debt investment
portfolio at least quarterly, or when there are changes in credit risks or other potential valuation concerns to identify and
evaluate whether an allowance for expected credit losses or impairment would be necessary.

We also invest in equity instruments of privately-held raw material companies in China for business and strategic

purposes. Investments in our unconsolidated joint venture raw material companies are classified as other assets and
accounted for under either the equity or cost method, depending on whether we have the ability to exercise significant
influence over their operations or financial decisions. We monitor our investments for impairment and record reductions in
carrying value when events or changes in circumstances indicate that the carrying value may not be recoverable.
Determination of impairment is highly subjective and is based on a number of factors, including an assessment of the
strength of the subsidiary’s management, the length of time and extent to which the fair value has been less than our cost
basis, the financial condition and near-term prospects of the subsidiary, fundamental changes to the business prospects of
the subsidiary, share prices of subsequent offerings, and our intent and ability to hold the investment for a period of time
sufficient to allow for any anticipated recovery in our carrying value.

For the years ended December 31, 2020 and 2018, we had no impairment charges. For the year ended December

31, 2019, we recorded an impairment charge of $1.1 million for a germanium materials company in China in which we
have a 25% ownership interest. After receiving such company’s preliminary first quarter 2019 financial results in early
April 2019 and its projections for significant losses going forward, we determined that this asset was fully impaired and
wrote the asset balance down to zero.

Fair Value of Investments

ASC Topic 820, Fair Value Measurement establishes three levels of inputs that may be used to measure fair value.

Level 1 instruments represent quoted prices in active markets. Therefore, determining fair value for Level 1

instruments does not require significant management judgment, and the estimation is not difficult.

Level 2 instruments include observable inputs other than Level 1 prices, such as quoted prices for similar

instruments in markets with insufficient volume or infrequent transactions (less active markets), issuer bank statements,
credit ratings, non-binding market consensus prices that can be corroborated with observable market data, model-derived
valuations in which all significant inputs are observable or can be derived principally from or corroborated with observable
market data for substantially the full term of the assets or liabilities, or quoted prices for similar assets or liabilities. These
Level 2 instruments require more management judgment and subjectivity compared to Level 1 instruments, including:

● Determining which instruments are most comparable to the instrument being priced requires management to

identify a sample of similar securities based on the coupon rates, maturity, issuer, credit rating, and instrument
type, and subjectively select an individual security or multiple securities that are deemed most similar to the
security being priced.

● Determining which model-derived valuations to use in determining fair value requires management judgment.
When observable market prices for similar securities or similar securities are not available, we price our
marketable debt instruments using non-binding market consensus prices that are corroborated with observable
market data or pricing models, such as discounted cash flow models, with all significant inputs derived from or
corroborated with observable market data.

Level 3 instruments include unobservable inputs to the valuation methodology that are significant to the
measurement of fair value of assets or liabilities. The determination of fair value for Level 3 instruments requires the most
management judgment and subjectivity.

46

Table of Contents

We place short-term foreign currency hedges that are intended to offset the potential cash exposure related to

fluctuations in the exchange rate between the United States dollar and Japanese yen. We measure the fair value of these
foreign currency hedges at each month end and quarter end using current exchange rates and in accordance with generally
accepted accounting principles. At quarter end any foreign currency hedges not settled are netted in “Accrued liabilities”
on the consolidated balance sheet and classified as Level 3 assets and liabilities. As of December 31, 2020 and 2019, the
net change in fair value from the placement of the hedge to settlement at each month end during the quarter had a de
minimis impact to the consolidated results. 

Impairment of Long-Lived Assets

We evaluate the recoverability of property, equipment and intangible assets in accordance with ASC Topic 360,

Property, Plant and Equipment. When events and circumstances indicate that long-lived assets may be impaired, we 
compare the carrying value of the long-lived assets to the projection of future undiscounted cash flows attributable to such 
assets. In the event that the carrying value exceeds the future undiscounted cash flows, we record an impairment charge 
against income equal to the excess of the carrying value over the asset’s fair value. Fair values are determined based on 
quoted market values, discounted cash flows or internal and external appraisals, as applicable. Assets held for sale are 
carried at the lower of carrying value or estimated net realizable value.  We had no “Assets held for sale” or any 
impairment of long-lived assets on the consolidated balance sheets as of December 31, 2020 and 2019. 

Stock-Based Compensation

We account for stock-based compensation in accordance with ASC Topic 718, Stock-based Compensation. Share-
based awards granted include stock options and restricted stock awards. We utilize the Black-Scholes option pricing model
to estimate the grant date fair value of stock options, which requires the input of highly subjective assumptions, including
estimating stock price volatility and expected term. Historical volatility of our stock price was used while the expected
term for our options was estimated based on historical option exercise behavior and post-vesting forfeitures of options, and
the contractual term, the vesting period and the expected term of the outstanding options. Further, we apply an expected
forfeiture rate in determining the amount of share-based compensation. We use historical forfeitures to estimate the rate of
future forfeitures. Changes in these inputs and assumptions can materially affect the measure of estimated fair value of our
stock compensation. The cost of restricted stock awards is determined using the fair value of our common stock on the date
of grant.

We recognize the compensation costs net of an estimated forfeiture rate over the requisite service period of the

options award, which is generally the vesting term of four years. Compensation expense for restricted stock awards is
recognized over the vesting period, which is generally one, three or four years. Stock-based compensation expense is
recorded in cost of revenue, research and development, and selling, general and administrative expenses. (see Note 1—
Summary of Significant Accounting Policies—Stock-Based Compensation).

Income Taxes

We account for income taxes in accordance with ASC topic 740, Income Taxes (“ASC 740”), which requires that
deferred tax assets and liabilities be recognized using enacted tax rates for the effect of temporary differences between the
book and tax bases of recorded assets and liabilities. ASC 740 also requires that deferred tax assets be reduced by a
valuation allowance if it is more likely than not that a portion of the deferred tax asset will not be realized. Our deferred tax
assets have been reduced to zero by valuation allowance.

We provide for income taxes based upon the geographic composition of worldwide earnings and tax regulations

governing each region, particularly China. The calculation of tax liabilities involves significant judgment in estimating the
impact of uncertainties in the application of complex tax laws, particularly in foreign countries such as China.

See Note 12—”Income Taxes” in the consolidated financial statements for additional information.

Change in Accounting Estimate – Useful Life of Equipment and Facilities

From time to time we review our estimates of the useful lives of our property, plant and equipment. As a result of

the review, we determined a portion of our manufacturing equipment was lasting longer than the estimate previously
established for the respective useful lives. Where appropriate, we extended the useful life of the manufacturing equipment
in our accounting records. In addition, the useful life of our buildings located in China was extended to better align with
industry standards. The changes in our estimate of the useful life, effective January 1, 2020, were made in order to remain
consistent with U.S. GAAP regarding management estimates. The effect of the change in the useful lives decreased our
manufacturing costs for the year ended December 31, 2020 by approximately $1.4 million and increased our basic and
diluted net income per share by approximately $0.03, respectively, as a result of lower depreciation expense.

Results of Operations

Overview

We were founded in 1986 to commercialize and enhance our proprietary VGF technology for producing high-

performance compound semiconductor substrates or wafers. We have one operating segment and two product lines:
specialty material substrates and raw materials used to make such substrates or other related products. We recorded our first
substrate sales in 1990 and our substrate products currently include indium phosphide (InP), gallium arsenide (GaAs) and
germanium (Ge) substrates used to produce semiconductor devices for use in applications such as fiber optic and wireless
telecommunications, light emitting diodes (LEDs), lasers and for solar cells for space and terrestrial photovoltaic
applications. We also sell raw materials through our participation in majority- and minority-owned subsidiaries and joint
ventures.

Operating Results

We manufacture all of our products in the People’s Republic of China (PRC or China), which generally has

favorable costs for facilities and labor compared with comparable facilities in the United States, Europe or Japan. Our
supply chain includes partial ownership of raw material companies in China (joint ventures). We believe this supply chain
arrangement provides us with pricing advantages, reliable supply and enhanced sourcing lead-times for key raw materials
which are central to our final manufactured products.

Our annual revenue increased in 2020 from $83.3 million in 2019 to $95.4 million in 2020.  This was an increase 

of 14.5%.  Our revenue decreased in 2019 by 18.7% to $83.3 million. For the years ended in 2018, 2017 and 2016 our 
revenue grew each year.  Our revenue increased in 2018 by 4% to $102.4 million, in 2017 by 21% to $98.7 million and in 
2016 by 5% to $81.3 million. In 2020, our gross margin increased from 29.8% in 2019 to 31.7% in 2020. Our gross margin 
declined in 2019 to 29.8% of total revenue from 36.2% of total revenue in 2018. For the years ended December 31, 2018, 
2017 and 2016 our gross margin grew each year. Gross margins improved to 36.2% of total revenue in 2018 from 34.9% of 
total revenue in 2017 and from 32.4% of total revenue in 2016. During the four years from 2012 to 2015 our revenue 
declined, primarily as a result of the adoption of an alternative technology, Silicon on Insulator (“SOI”), which entered the 
market in 2011. SOI enabled the RF switching chip in cell phones to function satisfactorily at a reduced cost. Before 2011, 
silicon did not perform adequately in this function due to power consumption, heat and speed issues.

In 2014, our revenue from InP began to grow and, in 2014 and 2015, the InP annual growth rate exceeded 50% 
year on year.  This mitigated the reduction in revenue from gallium arsenide and enabled us to return to annual growth in 
2016.  During this period, we believe our GaAs wafer business stabilized and our manufacturing yields improved. Our 
outlook for GaAs wafer substrates today is positive, as it is for InP and Ge substrates. The underlying end markets needing 
our wafer substrates are growing.  For example, InP wafer substrates are used for silicon photonics/data centers, passive 
optical networks and, more recently, 5G.  GaAs wafer substrates are used in LED lighting, industrial lasers and cell phones.  
We are continuing to improve our six-inch low defect density or low EPD GaAs substrates that are required for 3D-sensing 
using VCSELs.  We believe the relocation of our GaAs manufacturing line enables us to add capacity quickly for GaAs and 
InP in the future if market demands so require.

Revenue increased $12.1 million, or 14.5% in 2020 from $83.3 million in 2019. The $7.7 million increase in 
wafer substrate sales was the result of stronger GaAs demand in LED sensors used in the automobile industry and the 
industrial sensor market.  In addition, GaAs sales into wireless applications increased. Revenue from InP sales also 
increased. The InP revenue increase was driven by 5G infrastructure and data center upgrades (silicon photonics).  
Revenue from Ge wafer substrates increased, primarily as a result of higher demand from our customers in China. The $4.4 
million raw materials revenue increase as compared to the same period in 2019 was primarily the result of increased 
shipments of purified gallium due to stronger market demand and higher demand for pBN crucibles and OLED
manufacturing tools using pBN sold by our consolidated subsidiaries.

Revenue decreased $19.1 million, or 18.7% in 2019 from $102.4 million in 2018. The $13.2 million decrease in 

wafer substrate sales was the result of weaker GaAs demand in LED sensors used in the automobile industry and the 
industrial sensor market.  In addition, GaAs sales into wireless applications decreased.  Revenue from Ge wafer substrates 
also decreased, primarily as a result of lower demand from our customers in China.  These decreases were partially offset 
by an increase in InP revenue.  The $6.0 million raw materials revenue decrease as compared to the same period in 2018 
was primarily the result of the absence of revenue from raw gallium sales due to the deconsolidation of JiYa as of March 
11, 2019.  In addition there was a reduction in shipments of purified gallium due to lower market demand.

Sales to customers located outside of North America represented approximately 90% of our revenue during 2020,

2019 and 2018, respectively.

Revenue from customers in China increased in 2020 by 31.2%, primarily due to higher demand for refined 

gallium and pBN crucibles sold by our consolidated subsidiaries. In addition, revenue from GaAs wafer substrates 
increased. Revenue from customers in Taiwan increased in 2020 by 1.7%, primarily due to an increase in demand for 
wireless applications using GaAs wafer substrates, partially offset by a decline in InP revenue in Taiwan that was 
transferred to North America. Revenue from customers in Japan increased in 2020 by 21.8% as a result of increased 
demand for InP wafer substrates and GaAs used in wireless applications, partially offset by lower demand for pBN 
crucibles sold by our consolidated subsidiary. Revenue from customers in Asia Pacific decreased by 28.1% as a result of 
lower demand for pBN crucibles sold by our consolidated subsidiaries. Revenue from customers in Europe increased in 
2020 by 8.2%, primarily due to pBN crucibles sold by our consolidated subsidiary and Ge wafer substrates.  Revenue from 
customers in North America increased by 33.3% primarily due to increased demand for our InP wafer substrates partially 
offset by lower demand for wireless applications using our GaAs wafer substrates. 

Revenue from customers in China decreased in 2019 by 14.9%, primarily due to lower demand for our Ge wafer 

substrates. Revenue from customers in Europe decreased by 17.4%, primarily due to weaker demand for GaAs wafer 
substrates used in LED sensors for the automobile industry.  In addition, GaAs sales into wireless applications decreased.  
Revenue from customers in Taiwan decreased in 2019 by 19.3%, primarily due to a softening of demand from InP 
customers and a slow-down in both LED and wireless applications using GaAs substrate wafers. Revenue from customers 
in North America decreased by 17.9% as a result of lower demand for GaAs.  In addition revenue from one customer in 
Canada decreased as a result of weak demand from its primary optical device customer. Revenue from customers in Asia 
Pacific decreased by 10.6% as a result of lower demand for GaAs wafers used to produce industrial sensors.  Revenue from 
customers in Japan decreased in 2019 by 39.3% as a result of lower demand for raw materials.  In addition, there was lower 
demand for GaAs used in wireless applications and there was an aggressive inventory reduction program at one of our 
customers.

more units and a favorable change in product mix.

Gross profit decreased $12.2 million in 2019 as compared to 2018.  Gross margin in 2019 was 29.8% as compared 

to 36.2% in 2018.  The decrease in gross profit is attributed to the lower sales volume in 2019 as compared to 2018.  In 
addition our manufacturing costs did not drop commensurately, particularly in GaAs.

Selling, general and administrative expenses decreased $0.1 million, or 0.5%, to $19.2 million for 2020 compared
to $19.3 million for 2019. The lower selling, general and administrative expenses were primarily from lower travel-related
expenses driven by the COVID-19 pandemic, reimbursement of certain expenses from the local government in China for
relocating our manufacturing line to its province, lower license, tax and registration related expenses and lower
professional service-related expenses partially offset by higher personnel-related expenses and increase in our bad debt
expenses due to the poor financial condition of a few customers as a result of the COVID-19 pandemic.

Selling, general and administrative expenses increased $0.3 million, or 1.6%, to $19.3 million for 2019 compared

to $19.0 million for 2018. The higher selling, general and administrative expenses were primarily from higher stock
compensation expenses, VAT tax, legal expenses and consulting expenses related to our building construction in China
which were partially offset by lower office supplies, facility and freight related expenses.

Equity in income (loss) of unconsolidated joint ventures is the aggregate net income (loss) from our minority-
owned supply chain joint venture companies that are not consolidated. Equity in income (loss) of unconsolidated joint
ventures increased $2.0 million to an income of $0.1 million in 2020 from a loss of $1.9 million in 2019 as our
unconsolidated joint ventures reported better performance in 2020 as compared to 2019. The loss in 2019 includes an
impairment charge of $1.1 million from the germanium mining company in our raw material supply chain.

Equity in income (loss) of unconsolidated joint ventures decreased $0.8 million to a loss of $1.9 million in 2019
from a loss of $1.1 million in 2018 as our unconsolidated joint ventures reported worse performance in 2019 as compared
to 2018. The loss in 2019 includes an impairment charge of $1.1 million from the germanium mining company in our raw 
material supply chain. Further, there were no impairment charges in 2018.

Provision for income taxes for 2020 and 2019 were $2.0 million and $0.6 million, respectively, which were mostly

related to our consolidated wafer substrate subsidiaries in China and our two partially owned consolidated raw material
companies. No income taxes or benefits have been provided for U.S. operations as the income in the U.S. had been fully
offset by utilization of federal and state net operating loss carryforwards. Additionally, there is uncertainty of generating
future profit in the U.S., which has resulted in our deferred tax assets being fully reserved. Our estimated tax rate can vary
greatly from year to year because of the change or benefit in the mix of taxable income between our U.S. and China-based
operations.

against our net deferred tax assets of $19.8 million for the years 2020, 2019 and 2018.

We consider cash and cash equivalents, short-term investments and long-term investments as liquid and available

for use within two years in our current operations. Short-term investments and long-term investments are comprised of
money market accounts, certificates of deposit, corporate bonds and notes, and government securities. As of December 31,
2020, we and our consolidated joint ventures held approximately $60.5 million in cash and investments in foreign bank
accounts. This consists of $55.5 million held by our consolidated wafer substrate subsidiaries in China and $5.0 million
held by our two consolidated raw material subsidiaries in China.

Total cash and cash equivalents, short-term and long-term investments increased by $42.2 million in 2020. As

of December 31, 2020, our principal source of liquidity was $78.6 million, which consisted of cash and cash equivalents of
$72.6 million and short-term and long-term investments of $6.0 million. In 2020, cash and cash equivalents increased
by $45.7 million and short-term and long-term investments decreased by $3.5 million. The increase in cash and cash
equivalents of $45.7 million in 2020 was primarily due to net cash provided by financing activities of $52.7 million,
operating activities of $5.9 million and the effect of exchange rate changes of $3.6 million and partially offset by net cash
used in investing activities of $16.4 million.

Total cash and cash equivalents, short-term and long-term investments decreased by $3.1 million in 2019. As

of December 31, 2019, our principal source of liquidity was $36.3 million, which consisted of cash and cash equivalents of
$26.9 million and short-term investments of $9.4 million. In 2019, cash and cash equivalents increased by $10.4 million
and short-term and long-term investments decreased by $13.4 million. The increase in cash and cash equivalents of $10.4
million in 2019 was primarily due to net cash provided by operating activities of $12.7 million and financing

activities of $6.2 million and partially offset by net cash used in investing activities of $8.3 million and the effect of
exchange rate changes of $0.2 million.

Net cash provided by operating activities of $5.9 million for 2020 was primarily comprised of our net income of
$5.0 million, an adjustment of non-cash items of depreciation and amortization of $4.3 million, stock-based compensation
of $2.6 million, provision for doubtful accounts of $0.2 million, loss on disposal of equipment of $0.1 million, offset in part
by our net change in operating assets and liabilities of $6.3 million and gain on equity method investments of $0.1 million.
The $6.3 million net change in operating assets and liabilities primarily resulted from a $6.7 million increase in prepaid
expenses and other current assets, a $5.3 million increase in accounts receivable a $0.9 million increase in inventories and a
$0.1 million increase in other assets offset in part by a $2.3 million decrease in accounts payable, a $1.9 million decrease in
other long-term liabilities, including royalties and a $2.6 million decrease in accrued liabilities.

Net cash provided by operating activities of $12.7 million for 2019 was primarily comprised of an adjustment of

non-cash items of depreciation and amortization of $5.5 million, stock-based compensation of $2.3 million, impairment
charge on equity investee of $1.1 million, loss on equity method investments of $1.0 million, return on equity method
investments of $0.4 million, loss on disposal of equipment of $0.1 million, net change in operating assets and liabilities of
$4.0 million offset in part by our net loss of $1.6 million and gain from deconsolidation of a subsidiary of $0.2 million. The
$4.0 million net change in operating assets and liabilities primarily resulted from a $8.9 million decrease in inventories, a
$2.9 million decrease in prepaid expenses and other current assets, a $0.4 million decrease in accounts receivable, a $0.1
million increase in other long-term liabilities, including royalties, offset in part by a $4.0 million decrease in accrued
liabilities, a $3.1 million decrease in accounts payable and a $1.2 million increase in other assets.

Net cash provided by operating activities of $3.2 million for 2018 was primarily comprised of our net income of
$11.0 million, adjusted for non-cash items of depreciation and amortization of $4.9 million, stock-based compensation of
$1.9 million, loss on equity method investments of $1.1 million, amortization of marketable securities premium of $0.2
million offset in part by gain on disposal of property, plant and equipment of $0.1 million, which were partially offset by a
net change of $15.7 million in operating assets and liabilities. The $15.7 million net change in operating assets and
liabilities primarily resulted from a $14.6 million increase in inventories, a $4.6 million increase in prepaid expenses and
other current assets, a $1.9 million increase in other assets, a $0.3 million decrease in other long-term liabilities offset in
part by a $0.5 million increase in accrued liabilities, a $2.8 million decrease in accounts receivable, and a $2.3 million
increase in accounts payable.

Net cash used in investing activities of $16.4 million for 2020 was primarily due to property, plant and equipment

of $19.9 million in preparation for our new manufacturing sites, additional equipment for our Beijing site and equipment
and facility costs incurred by our consolidated subsidiaries and the purchases of marketable investment securities of $6.0
million, which were partially offset by proceeds from maturities and sales of available-for-sale debt securities of $9.4
million.

Net cash used in investing activities of $8.3 million for 2019 was primarily due to property, plant and equipment
of $21.8 million in preparation for our new manufacturing sites, additional equipment for our Beijing site and equipment
and facility costs incurred by our consolidated subsidiaries and the purchases of marketable investment securities of $8.7
million, which were partially offset by proceeds from maturities and sales of available-for-sale debt securities of $22.2
million.

Net cash used in investing activities of $30.8 million for 2018 was primarily due to property, plant and equipment

of $40.6 million in preparation for our new manufacturing sites, additional equipment for our Beijing site and equipment
and facility costs incurred by our consolidated subsidiaries and the purchases of marketable investment securities of $9.9
million, which were partially offset by proceeds from maturities and sales of available-for-sale debt securities of $19.6
million and proceeds from sale of property, plant and equipment of $0.1 million.

Net cash provided by financing activities was $52.7 million for 2020 which mainly consisted of the proceeds of
$47.6 million from issuance of common stock to noncontrolling interests net of issuance cost, $10.4 million from short-

term loan in China, $2.5 million from the exercise of common stock options, $0.4 million from sale of Tongmei shares to
noncontrolling interests partially offset by payments on short-term loans of $6.0 million and dividends paid by joint
ventures to their minority shareholders of $2.2 million.

Net cash provided by financing activities was $6.2 million for 2019, which mainly consisted of the proceeds of

$5.8 million from short-term loan in China, $0.3 million from the exercise of common stock options, $0.4 from sale of
previously consolidated subsidiary shares partially offset by the considerations paid in cash to repurchase subsidiary shares
from noncontrolling interests of $0.3 million.

Net cash provided by financing activities was $0.2 million for 2018, which mainly consisted of the proceeds of
$0.6 million from the exercise of common stock options, partially offset by the considerations paid in cash to repurchase
subsidiary shares from noncontrolling interests of $0.4 million.

On October 27, 2014, our Board of Directors approved a stock repurchase program pursuant to which we may

repurchase up to $5.0 million of our outstanding common stock.  These repurchases can be made from time to time in the
open market and are funded from our existing cash balances and cash generated from operations. During 2015, we
repurchased approximately 908,000 shares at an average price of $2.52 per share for a total purchase price
of approximately $2.3 million under the stock repurchase program. No shares were repurchased during 2020, 2019 and
2018 under this program. As of December 31, 2020, approximately $2.7 million remained available for future repurchases
under this program. Currently, we do not plan to repurchase additional shares. 

Dividends accrue on our outstanding Series A preferred stock, and are payable as and when declared by our board

of directors.  We have never paid or declared any dividends on the Series A preferred stock.  By the terms of the Series A
preferred stock, so long as any shares of Series A preferred stock are outstanding, neither the Company nor any subsidiary
of the Company shall redeem, repurchase or otherwise acquire any shares of common stock, unless all accrued dividends
on the Series A preferred stock have been paid.  During 2013 and 2015, we repurchased shares of our outstanding common
stock.  As of December 31, 2015, the Series A preferred stock had cumulative dividends of $2.9 million and we included
this amount in “Accrued liabilities” in our consolidated balance sheets. At the time we pay this accrued liability, our cash
and cash equivalents would be reduced.  We account for the cumulative year to date dividends on the Series A preferred
stock when calculating our earnings per share. See Item 5, Market for Registrant’s Common Equity, Related Stockholder
Matters and Issuer Purchases of Equity Securities in Part II.

As one of the first steps in the process of listing Tongmei on the STAR Market and going public, we sold 

approximately 7.28% of Tongmei to private equity investors for approximately $49 million in the aggregate. Pursuant to 
the Capital Investment Agreements with the Investors, each Investor has the right to require AXT to redeem any or all 
Tongmei shares held by such Investor at the original purchase price paid by such Investor, without interest, in the event of a 
material adverse change or if Tongmei does not achieve its IPO on or before December 31, 2022. This right is suspended 
when Tongmei submits its formal application to the CSRC.  Tongmei currently plans to submit its formal application to the 
CSRC in the third quarter of 2021.  However, if on December 31, 2022 the IPO application has been submitted and 
accepted by the CSRC or the stock exchange and such submission remains under review, then the date when such investor 
is entitled to exercise such redemption right shall be deferred to a date when such submission is rejected by the CSRC or 
stock exchange, or the date when Tongmei withdraws its IPO application. The process of going public on the STAR Market 
includes several periods of review and is therefore a lengthy process. Tongmei does not expect to complete the IPO until 
mid-2022. There can be no assurances that Tongmei will complete its IPO by December 31, 2022 or at all. In the event that 
investors exercise their redemption rights, we may be required to seek additional capital in order to redeem their Tongmei 
shares and there would be no assurances that such capital would be available on terms acceptable to us, if at all. Any 
redemptions could have a material adverse effect on our business, financial condition and results of operations. 

We believe that we have adequate cash and investments to meet our operating needs and capital expenditures over 

the next twelve months. If our sales decrease, however, our ability to generate cash from operations will be adversely 
affected which could adversely affect our future liquidity, require us to use cash at a more rapid rate than expected, and 
require us to seek additional capital.

On October 24, 2016, we filed with the SEC a registration statement on Form S-3, pursuant to which we may offer
up to $60 million of common stock, preferred stock, depositary shares, warrants, debt securities and/or units in one or more
offerings and in any combination. On November 4, 2016, the SEC declared the registration statement effective. On
November 4, 2019, the registration statement expired.

Cash from operations could be affected by various risks and uncertainties, including, but not limited to those set

forth below under Item 1A. “Risk Factors” above.

Bank Loans and Line of Credit

On November 6, 2018, the Company entered into a Credit Agreement (the “Credit Agreement”), by and between
the Company and Wells Fargo Bank, National Association (“Wells Fargo Bank”), which established a $10 million secured
revolving line of credit with a $1.0 million letter of credit sublimit facility. The revolving credit facility is collateralized by
substantially all of the assets of the Company located within the United States, subject to certain exceptions. The
commitments under the Credit Agreement expire on November 30, 2020 and any loans thereunder will bear interest at a
rate based on the daily one-month London Inter-bank Offered Rate (“LIBOR”) for the applicable interest period plus a
margin of 2.00%.  As of December 31, 2019, no loans or letters of credit were outstanding under the Credit Agreement. On
February 5, 2020, the Company entered into the First Amendment to Credit Agreement (the “First Amendment”), by and
between the Company and Wells Fargo Bank, which reduced the $10 million secured revolving line of credit under the
Credit Agreement to $7 million. The commitments under the Credit Agreement, as amended by the First Amendment,
expired on November 30, 2020. As of the date of this Annual Report on Form 10-K, no loans or letters of credit were
outstanding under the Credit Agreement, as amended by the First Amendment.

On August 9, 2019, Tongmei entered into a credit facility (the “Credit Facility”) with the Bank of China with a

$5.8 million line of credit at an annual interest rate of approximately 0.4% over the average interest rate quoted by the
National Interbank Funding Center. Accrued interest is calculated monthly and paid quarterly. The annual interest rate was
approximately 4.7% as of December 31, 2019. The Credit Facility is collateralized by Baoding Tongmei Xtal Technology
Co., Ltd.’s land use rights and all of its buildings located at its facility in Dingxing. The primary intended use of the Credit
Facility is for general purposes, which may include working capital and other corporate expenses.

On August 9, 2019, we borrowed $2.8 million against the Credit Facility. The repayment of the full amount was

due on August 9, 2020. On September 12, 2019 we borrowed an additional $2.8 million against the Credit Facility. The
repayment of the full amount was due on September 12, 2020. In August 2020, Tongmei repaid the full amount of the
credit facility including all outstanding accrued interest of approximately $5.9 million and simultaneously applied to renew
the credit facility. The process of repaying a loan and then renewing the loan is customary in China.

In September 2020, the August 2019 borrowing was renewed and funded against the credit facility with an interest

rate of 3.85%. The interest owed during the term of the loan was deducted prior to funding. The repayment of the loan is
due on March 22, 2021, however the credit facility contains an option to renew for an additional six months.

 In October 2020, the September 2019 borrowing was renewed and funded against the credit facility and an 

additional $2.7 million was approved and funded against the credit facility with the annual interest rate of 4.7%. Accrued 
interest is calculated monthly and paid quarterly.  The combined loan totals $5.6 million. The repayment of the $5.6 million 
is due on April 8, 2021, however, the credit facility contains an option to renew for an additional six months. As of 
December 31, 2020, $8.9 million was included in “Bank loan” in our consolidated balance sheets.

In February 2020, our consolidated subsidiary, BoYu, entered into a credit facility with the ICBC with a $1.4

million line of credit at an annual interest rate of approximately 0.15% over the loan prime rate. Accrued interest is
calculated monthly and paid quarterly. The annual interest rate was approximately 4.3% as of December 31, 2020. The
credit facility is collateralized by BoYu’s land use rights and its building located at its facility in Tianjin, China and

56

 
 
Table of Contents

BoYu’s accounts receivable. The primary intended use of the credit facility is for general purposes, which may include
working capital and other corporate expenses.

In March 2020, BoYu borrowed $0.4 million against the credit facility. The repayment of the full amount is due in
March 2021. In December 2020, BoYu borrowed an additional $1.1 million against the credit facility. As of December 31,
2020, $1.5 million was included in “Bank loan” in our consolidated balance sheets.

Off-Balance Sheet Arrangements

We did not have any off-balance sheet financing arrangements and have never established any special purpose
entities as defined under SEC Regulation S-K Item 303(a)(4)(ii). We have not entered into any options on non-financial
assets.

Contractual Obligations

We lease certain office space, warehouse facilities and equipment under long-term operating leases expiring at

various dates through July 2029. The majority of our lease obligations relate to our lease agreement for a nitrogen system
to be used during the manufacturing process for our facility in Dingxing, China. The equipment lease became effective in
August 2019 and will expire in July 2029. There are no variable lease payments, residual value guarantees or any
restrictions or covenants imposed by the equipment lease. The remainder relate to our lease agreement for our facility in
Fremont, California with approximately 19,467 square feet, which expires in 2023. There are no variable lease payments,
residual value guarantees or any restrictions or covenants imposed by the facility lease. All other operating leases have a
term of 12 months or less. Total rent expenses under these operating leases charged to selling, general and administrative
were approximately $322,000, $306,000 and $319,000 for the years ended December 31, 2020, 2019 and 2018,
respectively, primarily related to our Fremont facility. Total rent expenses under these operating leases charged to cost of
revenue were approximately $266,000, $112,000 and $0 for the years ended December 31, 2020, 2019 and 2018,
respectively, primarily related to the nitrogen system at our facility in Dingxing.

In 2010, we and a competitor entered into a royalty agreement with a term of eight years, terminating December 
31, 2018.  We and our related companies were granted a worldwide, nonexclusive, royalty bearing, irrevocable license to 
certain patents for the term on the agreement. Under this agreement we could have paid up to $7.0 million in royalty 
payments over eight years beginning in 2011 based on future royalty bearing sales. This agreement contained a clause that 
allowed us to claim a credit, starting in 2013, in the event that the royalty bearing sales for the year was lower than a pre-
determined amount set forth in this agreement. For the year ended December 31, 2018, royalty expense under this 
agreement was $565,000, which was net of a claim for credit of $10,000. 

In 2020, we and a competitor entered into a cross license and covenant agreement (the “Cross License
Agreement”), which has a term that begins on January 1, 2020 and expires on December 31, 2029. The Cross License
Agreement is a fixed-cost cross license and not a variable-cost cross license that is based on revenue or units. Under the
Cross License Agreement, we are obligated to make annual payments over a 10-year period. For the year ended December
31, 2020, royalty expense was $174,000.

Land Purchase and Investment Agreement

We  have  established  a  wafer  processing  production  line  in  Dingxing,  China.    In  addition  to  a  land  rights  and
building  purchase  agreement  that  we  entered  into  with  a  private  real  estate  development  company  to  acquire  our  new
manufacturing facility, we also entered into a cooperation agreement with the Dingxing local government.  In addition to
pledging its full support and cooperation, the Dingxing local government will issue certain tax credits to us as we achieve
certain milestones.  We, in turn, agreed to hire local workers over time, pay taxes when due and eventually demonstrate a
total investment of approximately $90 million in value, assets and capital.  The investment will include cash paid for the
land  and  buildings,  cash  on  deposit  in  our  name  at  local  banks,  the  gross  value  of  new  and  used  equipment  (including
future equipment that might be used for indium phosphide and germanium substrates production), the deemed value for our
customer list or the end user of our substrates (for example, the end users of the 3-D sensing VCSELs), a deemed value for
employment  of  local  citizens,  a  deemed  value  for  our  proprietary  process  technology,  other  intellectual  property,  other
intangibles and additional items of value.  There is no timeline or deadline by which this must be accomplished, rather it is
a good faith covenant entered into between AXT and the Dingxing local government.  Further, there is no specific penalty
contemplated if either party breaches the agreement, however the agreement does state that each party has a right to seek
from the other party compensation for losses.  Under certain conditions, the Dingxing local government may purchase the
land and building at the appraised value. We believe that such cooperation agreements are normal, customary and usual in
China and that the future valuation is flexible. We have a similar agreement with the city of Kazuo, China, although on a
smaller scale. The total investment targeted by AXT in Kazuo is approximately $15 million in value, assets and capital.

Purchase Obligations with Penalties for Cancellation

In the normal course of business, we issue purchase orders to various suppliers. In certain cases, we may incur a

penalty if we cancel the purchase order. As of December 31, 2020, we do not have any outstanding purchase orders that
will incur a penalty if cancelled by the Company.

Recent Accounting Pronouncements

Recent accounting pronouncements are detailed in Note 1 to our Consolidated Financial Statements included in

this Annual Report on Form 10-K.

Item 7A.  Quantitative and Qualitative Disclosures about Market Risk

Foreign Currency Risk

A significant portion of our business is conducted in currencies other than the U.S. dollar. Foreign exchange losses

have had a material adverse effect on our operating results and cash flows in the past and could have a material adverse
effect on our operating results and cash flows in the future. If we do not effectively manage the risks associated with this
currency risk, our revenue, cash flows and financial condition could be adversely affected. Although during 2019 and 2018,
we recorded a foreign exchange gain of $321,000 and $165,000, respectively, during 2020 we recorded net foreign
exchange loss of $411,000, included as part of other income, net in our consolidated statements of operation. We incur
foreign currency transaction exchange gains and losses due to operations in general. In the future we may experience
foreign exchange losses on our non-functional currency denominated receivables and payables to the extent that we have
not mitigated our exposure. Foreign exchange losses could have a materially adverse effect on our operating results and
cash flows.

Our product sales to Japanese customers are typically invoiced in Japanese yen. As such we have foreign
exchange exposure on our accounts receivable and on any Japanese yen denominated cash deposits. To partially protect us
against fluctuations in foreign currency resulting from accounts receivable in Japanese yen, starting in 2015, we instituted a
foreign currency hedging program. We place short term hedges that are intended to offset the potential cash exposure
related to fluctuations in the exchange rate between the United States dollar and Japanese yen. We measure the fair value of
these hedges at each month end and quarter end using current exchange rates and in accordance with generally accepted
accounting principles. At quarter end and year end any foreign currency hedges not settled are netted on the consolidated
balance sheet and consolidated balance sheet, respectively, and classified as Level 3 assets and liabilities. As of December
31, 2020 the net change in fair value from the placement of the hedge to settlement at each month end during the quarter
had a de minimis impact to the consolidated results.

The functional currency for our foreign operations is the renminbi, the local currency of China, and in the future

we may establish short term hedges covering renminbi. Most of our operations are conducted in China and most of our
costs are incurred in Chinese renminbi, which subjects us to fluctuations in the exchange rates between the U.S. dollar and
the Chinese renminbi. We incur transaction gains or losses resulting from consolidation of expenses incurred in local
currencies for our Chinese subsidiaries, as well as in translation of the assets and liabilities at each balance sheet date. Our
financial results could be adversely affected by factors such as changes in foreign currency exchange rates or weak
economic conditions in foreign markets, including the revaluation by China of the renminbi, and any future adjustments
that China may make to its currency such as any move it might make to a managed float system with opportunistic
interventions. We may also experience foreign exchange losses on our non-functional currency denominated receivables
and payables.

We currently are using a hedging program to minimize the effects of currency fluctuations relating to the
Japanese yen. While we may apply this program to other currencies, such as the Chinese renminbi, our hedging position is
partial and may not exist at all in the future. It may not succeed in minimizing our foreign currency fluctuation
risks. Our primary objective in holding these instruments is to reduce the volatility of earnings and cash flows associated
with changes in foreign currency. The program is not designated for trading or speculative purposes. The company may
choose not to hedge certain foreign exchange exposures for a variety of reasons, including but not limited to accounting
considerations and the prohibitive economic cost of hedging particular exposures. However, even with our hedging
program, we still experience losses on foreign exchange from time to time.

The primary objective of our investment activities is to preserve principal while maximizing income without

significantly increasing risk. Financial instruments that potentially subject us to concentration of credit risk consist
primarily of cash and cash equivalents, short-term investments, and accounts receivable. We invest primarily in money
market accounts, certificates of deposits, corporate bonds and notes, and government securities. We are exposed to credit
risks in the event of default by the issuers to the extent of the amount recorded on the consolidated balance sheets. These
securities are generally classified as available-for-sale and consequently are recorded on the balance sheet at fair value with
unrealized gains or losses reported as a separate component of accumulated other comprehensive income (loss), net of
estimated tax, further reduced by a valuation allowance for expected credit losses, if any. Our cash, cash equivalents and
short-term investments and long-term investments are in high-quality instruments placed with major banks and financial
institutions and commercial paper. We have no investments in auction rate securities.

Credit Risk

We perform ongoing credit evaluations of our customers’ financial condition, and limit the amount of credit
extended when deemed necessary, but generally do not require collateral. The credit risk in our accounts receivable is
mitigated by our credit evaluation process and the geographical dispersion of sales transactions. Two customers accounted
for 11% and 10% of our accounts receivable as of December 31, 2020 and three customers accounted for 14%, 13% and
12% of our accounts receivable as of December 31, 2019.

Equity Risk

As part of our supply chain strategy, we maintain minority investments in privately-held raw material companies

located in China either invested directly by us and our subsidiaries or through our consolidated joint venture companies.
These minority investments are reviewed for other than temporary declines in value on a quarterly basis. These investments
are classified as other assets in the consolidated balance sheets and accounted for under either the equity or cost method,
depending on whether we have the ability to exercise significant influence over their operations or financial decisions. We
monitor our investments for impairment and record reductions in carrying value when events or changes in circumstances
indicate that the carrying value may not be recoverable. We own 25% of a germanium mining company. In 2019, we wrote
down our investment in this company to zero resulting in an impairment charge of $1.1 million. Reasons for other than
temporary declines in value include whether the related company would have insufficient cash flow to operate for the next
twelve months, significant changes in the operating performance and changes in market conditions. As of December 31,
2020 and 2019, we did not maintain any direct investments under the cost method. Our minority investments under the
equity method as of December 31, 2020 and 2019 totaled $6.4 million and $6.0 million, respectively.

Item 9.  Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

None.

Item 9A.  Controls and Procedures

Evaluation of Disclosure Controls and Procedures  

Our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, evaluated

the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered
by this Annual Report on Form 10-K. Based upon this evaluation, our Chief Executive Officer and Chief Financial Officer
have concluded that our disclosure controls and procedures as defined under Exchange Act Rules 13a-15(e) and 15d-15(e)  
were effective at the reasonable assurance level to ensure that information required to be disclosed in our Securities 
Exchange Act reports is recorded, processed, summarized and reported within the time periods specified by the Securities 
and Exchange Commission and is accumulated and communicated to management, including our Chief Executive Officer 
and our Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. 

Our disclosure controls and procedures include components of our internal control over financial reporting.

Management’s assessment of the effectiveness of our internal control over financial reporting is expressed at the level of
reasonable assurance because a control system, no matter how well designed and operated, can provide only reasonable
assurance that the control system’s objectives will be met.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial
reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. Internal control over financial
reporting is a process designed by, or under the supervision of, our Chief Executive Officer and Chief Financial Officer,
and implemented by our Board of Directors, management and other personnel to provide reasonable assurance regarding
the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with
U.S. GAAP. Internal control over financial reporting includes those policies and procedures that:

● pertain to the maintenance of records that in reasonable detail accurately and fairly reflect our transactions

and dispositions of our assets;

● provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial
statements in accordance with U.S. GAAP, and that receipts and expenditures are being made only in
accordance with authorizations of our management and directors; and

● provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or

disposition of our assets that could have a material effect on the consolidated financial statements.

Because of inherent limitations, internal control over financial reporting may not prevent or detect misstatements.

Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become
inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may
deteriorate.

Our management, under the supervision and with the participation of our Chief Executive Officer and Chief

Financial Officer, has assessed the effectiveness of our internal control over financial reporting as of December 31, 2020
based on the criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of
Sponsoring Organizations of the Treadway Commission (COSO). Management has concluded that our internal control over
financial reporting was effective as of December 31, 2020.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of AXT, Inc.

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of AXT, Inc. (a Delaware corporation) and its subsidiaries
(the “Company”) as of December 31, 2020 and 2019, and the related consolidated statements of operations, comprehensive
income (loss), stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2020, and
the  related  notes  (collectively  referred  to  as  the  “consolidated  financial  statements”).  In  our  opinion,  the  consolidated
financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2020
and 2019, and the results of its operations and its cash flows for each of the three years in the period ended December 31,
2020, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These  consolidated  financial  statements  are  the  responsibility  of  the  Company’s  management.  Our  responsibility  is  to
express an opinion on the Company’s consolidated financial statements based on our audits. We are a public accounting
firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be
independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and
regulations of the Securities and Exchange Commission and the PCAOB.

We  conducted  our  audits  in  accordance  with  the  standards  of  the  PCAOB.  Those  standards  require  that  we  plan  and
perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material
misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an
audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of
internal control over financial reporting. Accordingly, we express no such opinion.

Our  audits  included  performing  procedures  to  assess  the  risks  of  material  misstatement  of  the  consolidated  financial
statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included
examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our
audits also included evaluating the accounting principles used and significant estimates made by management, as well as
evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable
basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial
statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts
or  disclosures  that  are  material  to  the  consolidated  financial  statements  and  (2)  involved  our  especially  challenging,
subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the
consolidated  financial  statements,  taken  as  a  whole,  and  we  are  not,  by  communicating  the  critical  audit  matter  below,
providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Inventories – Reserve for Excess and Obsolete Inventory

As  described  in  Notes  1  and  3  to  the  consolidated  financial  statements,  the  Company’s  consolidated  inventories  balance
was  $51.5  million  as  of  December  31,  2020,  which  was  net  of  a  reserve  of  $17.7  million  for  excess  and  obsolete
inventories. The Company’s inventories are stated at the lower of weighted average costs (approximated by standard cost)
or net realizable value. The Company routinely evaluates the levels of its inventories in light of current market conditions
in order to identify excess and obsolete inventories, and to provide a reserve for certain inventories to their estimated net
realizable  value  based  upon  the  age,  quality  and  life  expectancy  of  the  product,  and  the  projections  for  sale  of  the
completed products. If actual demand were to be substantially lower than estimated, there could be a significant adverse
impact on the carrying value of inventories and results of operations.

The principal considerations for our determination that performing procedures relating to reserve for excess and obsolete
inventories is a critical audit matter are the significant amount of judgment by management in developing the assumptions
of the forecasted product demand, which in turn led to significant auditor judgment, subjectivity, and effort in performing

66

Table of Contents

audit  procedures  and  evaluating  audit  evidence  relating  to  the  forecasted  product  demand.  Additionally,  for  certain  new
product launches there may be limited historical data with which to evaluate forecasts.

Addressing  the  matter  involved  performing  procedures  and  evaluating  audit  evidence  in  connection  with  forming  our
overall  opinion  on  the  consolidated  financial  statements.  These  procedures  included  testing  the  effectiveness  of  internal
controls  relating  to  management’s  reserve  for  excess  and  obsolete  inventories,  including  internal  controls  over  the
development  of  assumptions  related  to  forecasted  product  demand.  The  procedures  also  included,  among  others,  testing
management’s  process  for  developing  the  reserve  for  excess  and  obsolete  inventories,  testing  the  completeness  and
accuracy  of  the  underlying  data  used  in  the  estimate,  and  evaluating  management’s  assumptions  of  forecasted  product
demand. Evaluating management’s demand forecast for reasonableness involved considering historical sales or usage by
product,  comparing  prior  period  estimates  to  actual  results  of  the  same  period,  and  determining  whether  the  demand
forecast used was consistent with evidence obtained in other areas of the audit.

AXT, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1. The Company and Summary of Significant Accounting Policies

The Company

AXT, Inc. (“AXT”, “the Company”, “we,” “us,” and “our” refer to AXT, Inc. and its consolidated subsidiaries) is 

a worldwide materials science company that develops and produces high-performance compound and single element 
semiconductor substrates, also known as wafers.  Our consolidated subsidiaries produce and sell certain raw materials 
some of which are used in our substrate manufacturing process and some of which are sold to other companies.

Our substrate wafers are used when a typical silicon substrate wafer cannot meet the conductive requirements of a 

semiconductor or optoelectronic device.  The dominant substrates used in producing semiconductor chips and other 
electronic circuits are made from silicon. However, certain chips may become too hot or perform their function too slowly 
if silicon is used as the base material.  In addition, optoelectronic applications, such as LED lighting and chip-based lasers, 
do not use silicon substrates because they require a wave form frequency that cannot be achieved using silicon. Alternative 
or specialty materials are used to replace silicon as the preferred base in these situations. Our wafers provide such 
alternative or specialty materials. We do not design or manufacture the chips. We add value by researching, developing and 
producing the specialty material wafers. We have two product lines: specialty material substrates and raw materials integral
to these substrates. In 2020, our substrate product group generated 79% of our revenue and raw materials product group
generated 21%. Our compound substrates combine indium with phosphorous (indium phosphide: InP) or gallium with
arsenic (gallium arsenide: GaAs). Our single element substrates are made from germanium (Ge).

Our raw materials include purified gallium, InP based material and pBN crucibles. We use purified gallium in 
producing our GaAs substrates and also sell purified gallium in the open market to other companies for use in magnetic 
materials, high temperature thermometers and growing single crystal ingots including gallium arsenide, gallium nitride, 
gallium antimonite, gallium phosphide and other materials and alloys.  Pyrolytic boron nitride (pBN) crucibles are used in 
the high temperature (typically in the range 500 C to 1,500 C) growth process of single crystal ingots and epitaxial layer 
growth in MBE reactors.  We use these pBN crucibles in our own ingot growth processes and also sell them in the open 
market to other companies. 

Principles of Consolidation

The consolidated financial statements include the accounts of AXT, and our consolidated subsidiaries, Beijing
Tongmei Xtal Technology Co., Ltd. (“Tongmei”), Baoding Tongmei Xtal Technology Co., Ltd. (“Baoding Tongmei”),
ChaoYang Tongmei Xtal Technology Co., Ltd. (“ChaoYang Tongmei”), ChaoYang LiMei Semiconductor Technology Co.,
Ltd. (“ChaoYang LiMei”), Nanjing JinMei Gallium Co., Ltd. (“JinMei”), ChaoYang JinMei Gallium Ltd. (“ChaoYang
JinMei”), MaAnShan JinMei Gallium Ltd., and Beijing BoYu Semiconductor Vessel Craftwork Technology Co., Ltd.
(“BoYu”). Baoding Tongmei is located in the city of Dingxing, China. Each of ChaoYang Tongmei and ChaoYang LiMei is
located in the city of Kazuo, China. All significant inter-company accounts and transactions have been eliminated.
Investments in business entities in which we do not have controlling interests, but have the ability to exercise significant
influence over operating and financial policies (generally 20-50% ownership), are accounted for by the equity method. For
the years ended 2020 and 2019, we have five companies accounted for by the equity method. For the majority-owned
subsidiaries that we consolidate, we reflect the portion we do not own as either noncontrolling interests in stockholder’s
equity or as redeemable noncontrolling interests in temporary equity on our consolidated balance sheets and in our
consolidated statements of operations.

When market conditions are warranted, we intend to construct facilities at the ChaoYang LiMei location to

provide us with additional production capacity. For the years ended 2020 and 2019, expenses associated with ChaoYang
LiMei had a de minimis impact on our consolidated financial statements.

73

Table of Contents

As discussed in Note 6, “Investments in Privately-Held Raw Material Companies”, effective as of March 11,

2019, we reduced our ownership in Beijing JiYa Semiconductor Material Co., Ltd. (“JiYa”) from 46% to 39% by selling a 
portion of our JiYa shares to our investor partner, which is also JiYa’s landlord. As a result of this transaction, our investor 
partner became the largest shareholder of JiYa and assumed the right to appoint the general manager of JiYa and thereby 
exercised greater control over JiYa’s long-term strategic direction.  Further, although our Chief Executive Officer remains 
on the board, as of March 11, 2019 he was no longer the chairman of JiYa’s board of directors and our Chief Financial 
Officer was no longer a member of JiYa’s board of financial supervisors. Therefore, we deconsolidated JiYa from our 
consolidated financial statements as of March 11, 2019 in accordance with Accounting Standards Codification (“ASC”) 
Topic 810, Consolidation (“ASC 810”). As of March 12, 2019, we accounted for our retained investment in JiYa under the
equity method of accounting, as we continue to exercise significant influence.

Our consolidated balance sheet as of December 31, 2018, as reported, included JiYa’s assets and liabilities, after
all significant inter-company accounts and transactions were eliminated. Our consolidated balance sheet as of December
31, 2020 and 2019, as reported, does not include the assets and liabilities of JiYa, since we deconsolidated JiYa as of March
11, 2019. Our consolidated statement of operations for the year 2019 includes JiYa’s results for the period through March
11, 2019.

As discussed in Note 6, in May 2019, we purchased the remaining 3% ownership interest of JinMei from retiring

members of the JinMei management team for approximately $413,000. As a result, our ownership of JinMei increased
from 97% to 100%. As of June 1, 2019, we referred to JinMei as a wholly-owned subsidiary instead of a significantly
controlled subsidiary and reduced the carrying value of the corresponding noncontrolling interests to zero. Before August
1, 2020, our ownership of ChaoYang JinMei was 100%. In August 2020, we sold an 8.5% ownership interest to current
members of the ChaoYang JinMei management team for approximately $396,000. As a result, our ownership of ChaoYang
JinMei decreased from 100% to 91.5%. As of August 2020, we referred to ChaoYang JinMei as a significantly controlled
subsidiary instead of a wholly-owned subsidiary.

During the quarter ended December 31, 2020, Tongmei entered into two sets of definitive transaction documents,
each consisting of a capital increase agreement along with certain supplemental agreements in substantially the same form
(collectively, the “Capital Increase Agreements”), with several private equity investors in China.

In preparation for Tongmei’s application for a listing on the Shanghai Stock Exchange’s Sci-Tech innovAtion 
boaRd (the “STAR Market”), in late December we reorganized our entity structures in China.  JinMei and BoYu and its 
subsidiaries were assigned to Tongmei and effectively merged with Tongmei although they retained their own respective 
legal entity status and are wholly owned subsidiaries of Tongmei.  The 33% minority interest stakeholders of BoYu
converted their ownership to a 7.59% minority interest in Tongmei.  The 8.5% minority interest stakeholders, employees of
JinMei, converted their ownership to a 0.38% minority interest in Tongmei. Further, a number of employees, key managers
and contributors purchased a 0.4% minority interest in Tongmei. As of December 31, 2020, Tongmei’s noncontrolling
interests totaled 8.37%. Additionally, Baoding Tongmei and ChaoYang Tongmei, were assigned to Tongmei as wholly 
owned subsidiaries.  AXT remains the controlling stakeholder of Tongmei and holds a majority of the Board of Director 
positions of Tongmei.  The reorganization does not result in any change to the consolidated financials of AXT. 

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United
States of America (“U.S. GAAP”) requires management to make estimates, judgments and assumptions. We believe that
the estimates, judgments, and assumptions upon which management relies are reasonable based on information available at
the  time  that  these  estimates,  judgments,  and  assumptions  are  made.  These  estimates,  judgments,  and  assumptions  can
affect the reported amounts of assets and liabilities as of the date of the consolidated financial statements as well as the
reported  amounts  of  revenues  and  expenses  during  the  periods  presented.  To  the  extent  there  are  material  differences
between these estimates and actual results, our consolidated financial statements would be affected.

74

Table of Contents

Fair Value of Financial Instruments

The carrying amounts of certain of our financial instruments including cash and cash equivalents, short-term
investments and long-term investments, accounts receivable, accounts payable and accrued liabilities approximate fair
value due to their short maturities. Certain cash equivalents and investments are required to be adjusted to fair value on a
recurring basis. See Note 2.

Fair Value of Investments

ASC Topic 820, Fair value measurement (“ASC 820”) establishes three levels of inputs that may be used to

measure fair value.

Level 1 instruments represent quoted prices in active markets. Therefore, determining fair value for Level 1

instruments does not require significant management judgment, and the estimation is not difficult.

Level 2 instruments include observable inputs other than Level 1 prices, such as quoted prices for similar

instruments in markets with insufficient volume or infrequent transactions (less active markets), issuer bank statements,
credit ratings, non-binding market consensus prices that can be corroborated with observable market data, model-derived
valuations in which all significant inputs are observable or can be derived principally from or corroborated with observable
market data for substantially the full term of the assets or liabilities, or quoted prices for similar assets or liabilities. These
Level 2 instruments require more management judgment and subjectivity compared to Level 1 instruments, including:

● Determining which instruments are most comparable to the instrument being priced requires management to

identify a sample of similar securities based on the coupon rates, maturity, issuer, credit rating, and instrument
type, and subjectively select an individual security or multiple securities that are deemed most similar to the
security being priced.

● Determining which model-derived valuations to use in determining fair value requires management judgment.

When observable market prices for similar securities or comparable securities are not available, we price our
marketable debt instruments using non-binding market consensus prices that are corroborated with observable
market data or pricing models, such as discounted cash flow models, with all significant inputs derived from or
corroborated with observable market data.

Level 3 instruments include unobservable inputs to the valuation methodology that are significant to the
measurement of fair value of assets or liabilities. The determination of fair value for Level 3 instruments requires the most
management judgment and subjectivity.

We place short-term foreign currency hedges that are intended to offset the potential cash exposure related to

fluctuations in the exchange rate between the United States dollar and Japanese yen. We measure the fair value of these
foreign currency hedges at each month end and quarter end using current exchange rates and in accordance with generally
accepted accounting principles. At quarter end any foreign currency hedges not settled are netted in “Accrued liabilities”
on the consolidated balance sheets and classified as Level 3 assets and liabilities. As of December 31, 2020 and 2019, the
net change in fair value from the placement of the hedge to settlement had a de minimis impact to the consolidated results.

Foreign Currency Translation

The functional currency of our Chinese subsidiaries is the renminbi, the local currency of China. Transaction gains

and losses resulting from transactions denominated in currencies other than the U.S. dollar or in the functional currencies
of our subsidiaries are included in “Other income, net” for the years presented. The transaction loss for the year ended
December 31, 2020 totaled $411,000. The transaction gain totaled $321,000 and $165,000 for the years ended December
31, 2019 and 2018, respectively. The assets and liabilities of the subsidiaries are translated at the rates of exchange on the
balance sheet date. Revenue and expense items are translated at the average rate of exchange for the

75

Table of Contents

period. Gains and losses from foreign currency translation are included in “Other comprehensive income (loss)” in the
consolidated statements of comprehensive income (loss), net of tax.

Revenue Recognition

We manufacture and sell high-performance compound semiconductor substrates including indium phosphide, 

gallium arsenide and germanium wafers, and our consolidated subsidiaries sell certain raw materials, including  high purity 
gallium (6N and 7N Ga), pyrolytic boron nitride (pBN) crucibles and boron oxide (B2O3). After we ship our products, 
there are no remaining obligations or customer acceptance requirements that would preclude revenue recognition. Our 
products are typically sold pursuant to purchase orders placed by our customers, and our terms and conditions of sale do 
not require customer acceptance. We account for a contract with a customer when there is a legally enforceable contract, 
which could be the customer’s purchase order, the rights of the parties are identified, the contract has commercial terms, 
and collectibility of the contract consideration is probable. The majority of our contracts have a single performance 
obligation to transfer products and are short term in nature, usually less than six months. Our revenue is measured based on 
the consideration specified in the contract with each customer in exchange for transferring products that are generally 
based upon a negotiated, formula, list or fixed price. Revenue is recognized when control of the promised goods is 
transferred to our customer, which is either upon shipment from our dock, receipt at the customer’s dock, or removal from 
consignment inventory at the customer’s location, in an amount that reflects the consideration we expect to be entitled to 
receive in exchange for those goods.

We have elected to account for shipping and handling as activities to fulfill the promise to transfer the goods.
Shipping and handling fees billed to customers in a sales transaction are recorded as an offset to shipping and handling
expenses. Sales taxes and value added taxes in foreign jurisdictions that are collected from customers and remitted to
governmental authorities are accounted for on a net basis and, therefore, are excluded from revenue.

We do not provide training, installation or commissioning services. We provide for future returns based on

historical data, prior experience, current economic trends and changes in customer demand at the time revenue is
recognized. We do not recognize any asset associated with the incremental cost of obtaining revenue generating customer
contracts. As such, sales commissions are expensed as incurred, given that the expected period of benefit is less than one
year.

Contract Balances

We receive payments from customers based on a billing schedule as established in our contracts. Contract assets

are recorded when we have a conditional right to consideration for our completed performance under the contracts.
Accounts receivables are recorded when the right to this consideration becomes unconditional. We do not have any
material contract assets as of December 31, 2020.

Contract liabilities
During the three and twelve months ended December 31, 2020, the Company
recognized $9,000 and $251,000, respectively, of revenue that was included in
the contract balances as of December 31, 2019.

In general, revenue disaggregated by product types and geography (See Note 14) is aligned according to the

nature and economic characteristics of our business and provides meaningful disaggregation of our results of operations.
Since we operate in one segment, all financial segment and product line information can be found in the consolidated
financial statements.

Practical Expedients and Exemptions

We elected to use the following practical expedients: (i) not to adjust the promised amount of consideration for the
effects of a significant financing component when we expect, at contract inception, that the period between our transfer of a
promised product or service to a customer and when the customer pays for that product or service will be one year or less;
(ii) to expense costs as incurred for costs to obtain a contract when the amortization period would have been one year or
less; (iii) not to assess whether promised goods or services are performance obligations if they are immaterial in the context
of the contract with the customer.

In addition, we do not disclose the value of unsatisfied performance obligations for contracts with an original

expected length of one year or less.

Accounting for Sales Taxes

We record sales taxes collected on sales of our products and for amounts not yet remitted to tax authorities as

accrued liabilities on our consolidated balance sheets.

Risks and Concentration of Credit Risk

Our business is very dependent on the semiconductor, lasers and optical industries which can be highly cyclical

and experience downturns as a result of economic changes, overcapacity, and technological advancements. Significant
technological changes in the industry or customer requirements, or the emergence of competitive products with new
capabilities or technologies, could adversely affect our operating results. In addition, a significant portion of our revenues
and net income is derived from international sales. Fluctuations of the United States dollar against foreign currencies and
changes in local regulatory or economic conditions, particularly in an emerging market such as China, could adversely
affect operating results.

We depend on a limited number of suppliers for certain raw materials, components and equipment used in
manufacturing our products, including quartz tubing and polishing solutions. We generally purchase these materials
through standard purchase orders and not pursuant to long-term supply contracts.

Financial instruments that potentially subject us to concentration of credit risk consist primarily of cash and cash
equivalents, investments, and accounts receivable. We invest primarily in money market accounts, certificates of deposit
and corporate bonds. The composition and maturities are regularly monitored by management. Such deposits are in excess
of the amount of the insurance provided by the federal government on such deposits. We are exposed to credit risks in the
event of default by the issuers to the extent of the amount recorded on the consolidated balance sheets.

We perform ongoing credit evaluations of our customers’ financial condition, and limit the amount of credit
extended when deemed necessary, but generally do not require collateral. The credit risk in our accounts receivable is
mitigated by our credit evaluation process and the geographical dispersion of sales transactions. Two customers accounted
for 11% and 10% of our accounts receivable as of December 31, 2020 and three customers accounted for 14%, 13% and
12% of our trade accounts receivable as of December 31, 2019.   

One customer represented 11% of our revenue for the year ended December 31, 2020. One customer represented

15% of our revenue for the year ended December 31, 2019. One customer represented 13% of our revenue for the year
ended December 31, 2018. Our top five customers, although not the same five customers for each period, represented 32%
of our revenue for the year 2020 and 40% of our revenue for 2019 and 35% of our revenue for 2018, respectively.

For the year ended December 31, 2020, one third-party customer for the raw materials products from our
consolidated subsidiaries accounted for over 10% of the revenue from raw materials sales. For the years ended December
31, 2019 and 2018, each of three third-party customers for the raw materials products from our consolidated subsidiaries
accounted for over 10% of the revenue from raw materials sales. Our subsidiaries and raw material joint ventures are a key
strategic benefit for us as they further diversify our sources of revenue.

Cash and Cash Equivalents

We consider investments in highly liquid instruments purchased with an original maturity of three months or less
to be cash equivalents. Cash equivalents consist primarily of certificate of deposits. Cash and cash equivalents are stated at
cost, which approximates fair value.

Short-Term and Long-Term Investments

We classify our investments in marketable securities as available-for-sale debt securities. Short-term and long-

term investments are comprised of available-for-sale marketable securities, which consist primarily of certificates of
deposit and corporate bonds. These investments are reported at fair value as of the respective balance sheet dates with
unrealized gains and losses included in accumulated other comprehensive income (loss) within stockholders’ equity on the
consolidated balance sheets. The amortized cost of securities is adjusted for amortization of premiums and accretion of
discounts to maturity. Such amortization is included in “Other income, net” in the consolidated statements of operations.
Realized gains and losses and declines in value judged to be other than temporary on available-for-sale securities are also
included in “Other income, net” in the consolidated statements of operations. The cost of securities sold is based upon the
specific identification method.

Accounts Receivable and Allowance for Doubtful Accounts and Sales Returns

Accounts receivable are recorded at the invoiced amount and are not interest bearing. We periodically review the

likelihood of collection on our accounts receivable balances and provide an allowance for doubtful accounts receivable
primarily based upon the age of these accounts. We evaluate receivables from U.S. customers with an emphasis on
balances in excess of 90 days and for receivables from customers located outside the U.S. with an emphasis on balances in
excess of 120 days and establish a reserve allowance on the receivable balances if needed. The reason for the difference in
the evaluation of receivables between foreign and U.S. customers is that U.S. customers have historically made payments
in a shorter period of time than foreign customers. Foreign business practices generally require us to allow customer
payment terms that are longer than those accepted in the United States. We assess the probability of collection based on a
number of factors, including the length of time a receivable balance has been outstanding, our past history with the
customer and their credit worthiness.

We exercise judgment when determining the adequacy of these reserves as we evaluate historical bad debt trends,

general economic conditions in the United States and internationally, and changes in customer financial conditions.
Uncollectible receivables are recorded as bad debt expense when all efforts to collect have been exhausted and recoveries
are recognized when they are received. As of December 31, 2020 and 2019, our accounts receivable, net balance was $24.6
million and $19.0 million, respectively, which was net of an allowance for doubtful accounts of $217,000 and $34,000 in
December 31, 2020 and 2019, respectively. During 2020, the allowance for doubtful accounts increased by $183,000 due to
the poor financial condition of a few customers. During 2019, the allowance for doubtful accounts decreased by $324,000
primarily due to the deconsolidation of JiYa. If actual uncollectible accounts differ substantially from our estimates,
revisions to the estimated allowance for doubtful accounts would be required, which could have a material impact on our
financial results for the future periods.

As of December 31, 2020 and 2019, the sales returns reserve (included in accrued liabilities) balance was $81,000

and $26,000, respectively. During 2020, we utilized $82,000 and reserved an additional $137,000 and during 2019, we
utilized $26,000 and reserved an additional $5,000.

Warranty Reserve

We maintain a warranty reserve based upon our claims experience during the prior twelve months and any

pending claims and returns of which we are aware. Warranty costs are accrued at the time revenue is recognized. As of
December 31, 2020 and 2019, accrued product warranties totaled $609,000 and $387,000, respectively. The increase in
accrued product warranties is primarily attributable to increased claims for quality issues experienced by approximately
four of our customers. If actual warranty costs or pending new claims differ substantially from our estimates, revisions to

78

Table of Contents

the estimated warranty liability would be required, which could have a material impact on our financial condition and
results of operations for future periods.

Inventories

Inventories are stated at the lower of cost (approximated by standard cost) or net realizable value. Cost is
determined using the weighted average cost method. Our inventory consists of raw materials as well as finished goods and
work-in-process that include material, labor and manufacturing overhead costs. We routinely evaluate the levels of our
inventory in light of current market conditions in order to identify excess and obsolete inventory, and we provide a reserve
for certain inventories to their estimated net realizable value based upon the age and quality of the product and the
projections for sale of the completed products. When a reserve is recorded, a new lower cost basis for that inventory is
established and subsequent changes in facts and circumstances do not result in the restoration or increase in the new cost
basis.

Property, Plant and Equipment

Property, plant and equipment are stated at cost less accumulated depreciation computed using the straight-line

method over the estimated economic lives of the assets, which vary from 1 to 39.5 years. Leasehold improvements are
amortized using the straight-line method over the shorter of the estimated useful life or the term of the lease. We generally
depreciate computer, software, office equipment, furniture and fixtures 3 to 5 years, machinery and equipment 1 to 20
years, automobiles 5 to 10 years, leasehold and building improvements over 10 years, or the lease term if shorter, and
buildings over 39.5 years. Repairs and maintenance costs are expensed as incurred.

Impairment of Long-Lived Assets

We evaluate property, plant and equipment and intangible assets for impairment. When events and circumstances
indicate that long-lived assets may be impaired, we compare the carrying value of the long-lived assets to the projection of
future undiscounted cash flows attributable to these assets. In the event that the carrying value exceeds the future
undiscounted cash flows, we record an impairment charge against income equal to the excess of the carrying value over the
assets’ fair value. Fair values are determined based on quoted market values, discounted cash flows or internal and external
appraisals, as applicable. We did not recognize any impairment charges of long-lived assets in 2020, 2019 and 2018.

Impairment of Investments

All available-for-sale debt securities are periodically reviewed for impairment. An investment is considered to be 

impaired when its fair value is less than its amortized cost basis and it is more likely than not that we will be required to 
sell the impaired security before recovery of its amortized cost basis.  Factors considered in determining whether a loss is 
temporary include the magnitude of the decline in market value, the length of time the market value has been below cost 
(or adjusted cost), credit quality, and our ability and intent to hold the securities for a period of time sufficient to allow for 
any anticipated recovery in market value.

We  also  invest  in  equity  instruments  of  privately-held  companies  in  China  for  business  and  strategic  purposes.
Investments in our unconsolidated joint venture companies are classified as other assets and accounted for under either the
equity or cost method, depending on whether we have the ability to exercise significant influence over their operations or
financial  decisions.  We  monitor  our  investments  for  impairment  and  record  reductions  in  carrying  value  when  events  or
changes in circumstances indicate that the carrying value may not be recoverable. Determination of impairment is highly
subjective and is based on a number of factors, including an assessment of the strength of each company’s management,
the length of time and extent to which the fair value has been less than our cost basis, the financial condition and near-term
prospects  of  the  subsidiary,  fundamental  changes  to  the  business  prospects  of  the    company,  share  prices  of  subsequent
offerings,  and  our  intent  and  ability  to  hold  the  investment  for  a  period  of  time  sufficient  to  allow  for  any  anticipated
recovery in our carrying value. We estimate fair value of our cost method investments considering available information
such as pricing in recent rounds of financing, current cash positions, earnings and cash flow forecasts, recent operational
performance and any other readily available market data.

79

Table of Contents

We  have  25%  ownership  interest  in  a  germanium  materials  company  in  China  and  we  incurred  an  impairment
charge during 2019.  After receiving such company’s preliminary first quarter 2019 financial results in early April 2019 and
its projections for significant losses going forward, we determined that this asset was fully impaired and wrote the asset
balance down to zero.  This resulted in a $1.1 million impairment charge in our first quarter 2019 financial results. Except
as  mentioned  above,  there  were  no  impairment  charges  for  the  remainder  of  these  investments  during  the  years  ended
December 31, 2020 and 2019.

Segment Reporting

We operate in one segment for the design, development, manufacture and distribution of high-performance

compound and single element semiconductor substrates and sale of raw materials integral to these substrates. Our chief
operating decision-maker has been identified as our Chief Executive Officer, who reviews operating results to make
decisions about allocating resources and assessing our performance for the Company. We discuss revenue and capacity for
both AXT and our joint ventures collectively, when determining capacity constraints and need for raw materials in our
business, and consider their capacity when determining our strategic and product marketing and advertising strategies.
While we consolidate our majority-owned or significantly controlled joint ventures, we do not allocate any portion of
overhead, interest and other income, interest expense or taxes to them. We therefore have determined that our joint venture
operations do not constitute an operating segment. Since we operate in one segment, all financial segment and product line
information can be found in the consolidated financial statements.

Stock-Based Compensation

We have employee stock option plans, which are described more fully in Note 10—"Employee Benefit Plans and

Stock-based Compensation”. We account for stock-based compensation in accordance with the provisions of ASC Topic
718, Compensation-Stock Compensation (“ASC 718”). We utilize the Black-Scholes option pricing model to estimate the
grant date fair value of stock options, which requires the input of highly subjective assumptions, including estimating stock
price volatility and expected term.  Stock-based compensation cost is measured at each grant date, based on the fair value
of the award, and is recognized as expense and as an increase in additional paid-in capital over the requisite service period
of the award.

Research and Development

Research and development costs consist primarily of salaries, including stock-based compensation expense and

related personnel costs, depreciation, materials and product testing which are expensed as incurred. Tangible assets
acquired for research and development purposes are capitalized if they have alternative future use.

Advertising Costs

Advertising costs, included in selling, general and administrative expenses, are expensed as incurred. Advertising

costs for the years ended December 31, 2020, 2019 and 2018 were insignificant.

Income Taxes

We account for income taxes in accordance with ASC Topic 740, Income Taxes (“ASC 740”), which requires that
deferred tax assets and liabilities be recognized using enacted tax rates for the effect of temporary differences between the
book and tax bases of recorded assets and liabilities. ASC 740 also requires that deferred tax assets be reduced by a
valuation allowance if it is more likely than not that a portion of the deferred tax asset will not be realized. The impact of
ASC 740 is more fully described in Note 12.

Comprehensive Income (Loss)

The components of other comprehensive income (loss) include unrealized gains and losses on marketable

securities and foreign currency translation adjustments. Comprehensive income (loss) is presented in the consolidated
statements of comprehensive income, net of tax. The balance of accumulated other comprehensive income (loss) is as
follows (in thousands):

Basic net income (loss) per share is computed using the weighted-average number of common shares outstanding

during the periods less shares of common stock subject to repurchase and non-vested stock awards. Diluted net income
(loss) per share is computed using the weighted-average number of common shares outstanding and potentially dilutive
common shares outstanding during the periods. The dilutive effect of outstanding stock options and restricted stock awards
is reflected in diluted earnings per share by application of the treasury stock method. Potentially dilutive common shares
consist of common shares issuable upon the exercise of stock options and vesting of restricted stock awards. Potentially
dilutive common shares are excluded from the computation of weighted-average number of common shares outstanding in
net loss years, as their effect would be anti-dilutive to the computation.

Recent Accounting Pronouncements

 Accounting Standard Update No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of

Credit Losses on Financial Instruments (“ASU 2016-13”) was issued in June 2016. Under ASU 2016-13, existing guidance
on reporting credit losses for trade and other receivables and available for sale debt securities have been replaced with a
new forward-looking “expected loss” model that has resulted in the earlier recognition of allowances for losses. Our
adoption of ASU 2016-13 and its subsequent series of amendments during the twelve months ended December 31, 2020
using the modified retrospective transition approach did not result in a material impact on our consolidated financial
statements. As part of our assessment of the adequacy of our allowances for credit losses, we consider a number of factors
including, but not limited to, customer credit ratings, bankruptcy filings, published or estimated credit default rates, age of
receivables, adequacy of our allowance for doubtful accounts and expected loss rates.

We manage our debt investments as a single portfolio of highly marketable securities that is intended to be
available to meet our current cash requirements. Certificates of deposit and corporate bonds are typically held until
maturity.

Historically, the gross unrealized losses related to our portfolio of available-for-sale debt securities were
immaterial, and primarily due to normal market fluctuations and not due to increased credit risk or other valuation
concerns. Gross unrealized losses on our available-for-sale debt securities as of December 31, 2020 was $2,000, and
historically, such gross unrealized losses have been temporary in nature and we believe that it is probable the principal and
interest will be collected in accordance with the contractual terms. We review our debt investment portfolio at least
quarterly, or when there are changes in credit risks or other potential valuation concerns, to identify and evaluate whether
an allowance for credit losses or impairment would be necessary. Factors considered in determining whether a loss is
temporary include the magnitude of the decline in market value, the length of time the market value has been below cost
(or adjusted cost), credit quality, and our ability and intent to hold the securities for a period of time sufficient to allow for
any anticipated recovery in market value.

A portion of our debt investments would generate a loss if we sold them on December 31, 2020.

We have made strategic investments in private companies located in China in order to gain access at a competitive

cost to raw materials that are critical to our substrate business (see Note 6). The investment balances for the non-
consolidated companies, are accounted for under the equity method and included in “Other assets” in the consolidated
balance sheets and totaled $6.4 million and $6.0 million as of December 31, 2020 and 2019, respectively. As of December
31, 2020, there were five companies accounted for under the equity method. The year ended December 31, 2019 includes
an impairment charge of $1.1 million for one of our minority investments (see Note 6). We had no impairment charges
during 2020 and 2018.

Fair Value Measurements

We invest primarily in money market accounts, certificates of deposit, corporate bonds and notes, and government

securities. ASC Topic 820, Fair Value Measurements and Disclosures (“ASC 820”), establishes three levels of inputs that
may be used to measure fair value. Level 1 instrument valuations are obtained from real-time quotes for transactions in
active exchange markets of the asset or identical assets. Level 2 instrument valuations are obtained from readily-
available, observable pricing sources for comparable instruments. Level 3 instrument valuations are obtained from
unobservable inputs in which there is little or no market data, which require us to develop our own assumptions. On a
recurring basis, we measure certain financial assets and liabilities at fair value, primarily consisting of our short-term and
long-term debt investments.

The type of instrument valued based on quoted market prices in active markets include our money market funds,
which are generally classified within Level 1 of the fair value hierarchy. We classify our available-for-sale debt securities
including certificates of deposit and corporate bonds as having Level 2 inputs. The valuation techniques used to measure
the fair value of these financial instruments having Level 2 inputs were derived from bank statements, quoted market
prices, broker or dealer statements or quotations, or alternative pricing sources with reasonable levels of price transparency.
There were no changes in valuation techniques or related inputs in the year ended December 31, 2020. There have been no
transfers between fair value measurement levels during the years ended December 31, 2020 and 2019.

We place short-term foreign currency hedges that are intended to offset the potential cash exposure related to

fluctuations in the exchange rate between the United States dollar and Japanese yen. We measure the fair value of these
foreign currency hedges at each month end and quarter end using current exchange rates and in accordance with generally
accepted accounting principles. At quarter end any foreign currency hedges not settled are netted in “Accrued liabilities”
on the consolidated balance sheets and classified as Level 3 assets and liabilities. As of December 31, 2020, the net change
in fair value from the placement of the hedge to settlement at each month end during the quarter had a de minimis impact
to the consolidated results.

Items Measured at Fair Value on a Nonrecurring Basis

Certain assets that are subject to nonrecurring fair value measurements are not included in the table above. These
assets include investments in privately-held companies accounted for by equity and cost method (See Note 6). For the year
ended December 31, 2019, we recognized an impairment charge of $1.1 million for one of our minority investments. We 
received its preliminary first quarter 2019 financial results in early April 2019 as well as its projections for significant 
losses going forward. Such projected losses would fully deplete our asset investment balance for this company in 2019.  
This company in which we have a minority investment is experiencing significant disruptions due to upgrades and repairs 
required to comply with stronger environmental regulations in China.  As a result, we determined that this asset was fully 
impaired and wrote the asset balance down to zero. We had no impairment charges for 2020 and 2018.

Note 4. Related Party Transactions

Effective as of March 11, 2019, we reduced our ownership in JiYa from 46% to 39% by selling a portion of our
JiYa shares to our investor partner, which is also JiYa’s landlord. Based on an independent third-party valuation analysis,
we sold these shares for $366,000.  Previously we were the largest shareholder of JiYa and as such, we had the right to 
appoint the general manager of JiYa and the ability to exercise control in substance over JiYa’s long-term strategic 
direction.  Further, our Chief Executive Officer was the chairman of JiYa’s board of directors and our Chief Financial 
Officer was a member of JiYa’s board of financial supervisors.  As a result of this transaction, our investor partner, Shanxi 
Aluminum Industrial Co., Ltd. became the largest shareholder of JiYa and assumed the right to appoint the general 
manager of JiYa and thereby exercised greater control over JiYa’s long-term strategic direction.  Further, although our 
Chief Executive Officer remains on the board, as of March 11, 2019, he was no longer chairman of JiYa’s board of 
directors and our Chief Financial Officer was no longer on JiYa’s board of financial supervisors.  

Previously, we accounted for JiYa’s financial performance under the consolidation method of accounting.  As a 

result of the changes, we began to account for JiYa’s financial performance under the equity method of accounting.  
Therefore, we deconsolidated JiYa from our consolidated financial statements as of March 11, 2019 in accordance with 
ASC 810. As of March 12, 2019, we accounted for our investment in JiYa under the equity method of accounting as we 
continue to have board representation and substantial ownership.  Pro-forma financials have not been presented because we
believe the effects were not material to our consolidated financial position and results of operations for all periods
presented. JiYa continues to be a related party to us after deconsolidation, from whom we may purchase raw materials for
production in the ordinary course of business from time to time.

Beginning in 2012, our consolidated joint venture, JinMei, became contractually obligated under an agency sales
agreement to sell raw material on behalf of its equity investment entity. JinMei bills the customers and remits the receipts,
net of its portions of sales commission, to this equity investment entity. For the years ended December 31, 2020, 2019 and
2018, JinMei recorded $0, $0 and $24,000 of income from agency sales, respectively, which were included in “Other
income, net” in the consolidated statements of operations.

In March 2012, Tongmei, entered into an operating lease for the land it owns with our consolidated joint venture,
BoYu. The lease agreement for the land of approximately 22,081 square feet commenced on January 1, 2012 for a term of 
10 years with annual lease payments of $24,000 subject to a 5% increase at each third year anniversary. The annual lease 
payment is due by January 31st of each year.

Tongmei also purchases raw materials from Donghai County Dongfang High Purity Electronic Materials Co., Ltd.

for production in the ordinary course of business. As of December 31, 2020 and 2019, there were no amounts payable
outstanding.

ChaoYang Tongmei also purchases raw materials from one of our equity investment entities, Emeishan Jia Mei
High Purity Metals Co. Ltd. (“Jiamei”), for production in the ordinary course of business. As of December 31, 2020 and
2019, there no amounts payable outstanding.

Tongmei and ChaoYang Tongmei also purchases raw materials from one of our equity investment entities,
Xilingol Tongli Germanium Refine Co. Ltd. (“Tongli”), for production in the ordinary course of business. As of December
31, 2020 and 2019, there no amounts payable outstanding.

In July 2017, Tongmei, provided an inter-company loan to JinMei in the amount of $768,000 in preparation for

the acquisition of the land use rights and the construction of a new building. The inter-company loan carries an interest rate
of 4.9% per annum. The principle is due in three installments between December 2021 and December 2023 while the
interest is due in December of each year. As of December 31, 2020, JinMei repaid principal and interest totaling $537,000
to Tongmei. As of December 31, 2020 and 2019, the remaining balance of principal and interest totaled $303,000 and
$285,000, respectively. JinMei, is in the process of relocating its manufacturing operations to the city of Kazuo, located in
the province of Liaoning near the Inner Mongolia Autonomous Region, near our own location.

In April 2016, our consolidated joint venture, BoYu, provided a personal loan of $177,000 to one of its executive
employees. This loan is collateralized by the officer’s shares in BoYu. The loan bears interest at 2.75% per annum. During
the three months ended June 30, 2017, the repayment of the principal and interest totaling $180,000 was received by our
consolidated joint venture. In November 2017, BoYu provided another personal loan of $291,000 to the same executive
employee. This loan bears interest at 2.75% per annum. Principal and accrued interest are due on November 30, 2020. In
May 2019, BoYu provided another personal loan of $146,000 to the same executive employee. This loan bears interest at
2.75% per annum. Principal and accrued interest are due at such time BoYu pays a dividend to its shareholders. In March
2020, BoYu provided another personal loan of $141,000 to the same executive employee. This loan bears interest at 2.75%
per annum. Principal and accrued interest are due on December 31, 2024. On December 25, 2020, the executive repaid the
principal of $612,000 and interest of $35,000 of the personal loans to BoYu. As of December 31, 2020 and 2019, the
balances, including both principal and accrued interest, were $0, and $449,000, respectively, and included in “Other assets”
in our consolidated balance sheets.

On November 2, 2017, our consolidated joint venture, BoYu, raised additional capital in the amount of $2 million

in cash from a third-party investor through the issuance of shares equivalent to 10% ownership of BoYu. This third-party
investor is an immediate family member to the owner of one of BoYu's customers. For the years ended December 31, 2020
and 2019, BoYu has recorded $0.3 million and $0.2 million in revenue from this customer, respectively. As of December
31, 2020 and 2019, amounts receivable of $0 and $12,000, respectively, were included in “Accounts receivable” in our
consolidated balance sheets. In December 2020, we purchased shares equivalent to 4% of BoYu from the same third-party
investor for $1.6 million and the remaining 6% was sold to another third-party investor.

Our Related Party Transactions Policy seeks to prohibit all conflicts of interest in transactions between related

parties and us, unless they have been approved by our Board of Directors. This policy applies to all of our
employees, directors, and our consolidated subsidiaries. Our executive officers retain board seats on the Board of Directors
of the companies in which we have invested in our China joint ventures. See Note 6 for further details.

As of December 31, 2020, the balance of construction in progress was $24.5 million, of which $14.2 million was

related to our buildings in our new Dingxing and Kazuo locations, $4.0 million was for manufacturing equipment
purchases not yet placed in service and $6.3 million was from our construction in progress for our other consolidated
subsidiaries. As of December 31, 2019, the balance of construction in progress was $61.8 million, of which $48.8 million
was related to our buildings in our new Dingxing and Kazuo locations, $3.4 million was for manufacturing equipment
purchases not yet placed in service and $9.6 million was from our construction in progress for our other consolidated
subsidiaries. 

Depreciation and amortization expense was $4.3 million, $5.5 million and $4.9 million for the years ended

December 31, 2020, 2019 and 2018, respectively.

From time to time we review our estimates of the useful lives of our property, plant and equipment. As a result of

the review, we determined a portion of our manufacturing equipment was lasting longer than the estimate previously
established for the respective useful lives. Where appropriate, we extended the useful life of the manufacturing equipment
in our accounting records. In addition, the useful life of our buildings located in China was extended to better align with
industry standards. The changes in our estimate of the useful life, effective January 1, 2020, were made in order to remain
consistent with U.S. GAAP regarding management estimates. The effect of the change in the useful lives decreased our
manufacturing costs for the year ended December 31, 2020 by approximately $1.4 million and increased our basic and
diluted net income per share by approximately $0.03, respectively, as a result of lower depreciation expense.

* These percentages reflect the ownership currently in effect upon the completion of the reorganization in China.
** In preparation for Tongmei’s application for a listing on the STAR Market, in late December 2020 we reorganized our entity 
structures in China.  JinMei and BoYu and its subsidiaries, previously organized under AXT, Inc., were assigned to Tongmei and 
effectively merged with Tongmei although they retained their own respective legal entity status and are wholly owned subsidiaries of 
Tongmei.  The 33% minority interest stakeholders of BoYu converted their ownership to a 7.59% minority interest in Tongmei.  The
 8.5% minority interest stakeholders, employees of JinMei, converted their ownership to a 0.38% minority interest in Tongmei. Further, a
number of employees, key managers and contributors, purchased a 0.4% minority interest in Tongmei. As of December 31, 2020,
Tongmei’s noncontrolling interests totaled 8.37%.

Effective as of March 11, 2019, we reduced our ownership in JiYa from 46% to 39% by selling a portion of our 
JiYa shares to our investor partner, which is also JiYa’s landlord.  Based on an independent third-party valuation analysis, 
we sold these shares for $366,000.  Previously, we were the largest shareholder and, as such, we had the right to appoint the 
general manager of JiYa and the ability to exercise control in substance over JiYa’s long-term strategic direction.  Further, 
our Chief Executive Officer was the chairman of JiYa’s board of directors and our Chief Financial Officer was a member of 
JiYa’s board of financial supervisors.  As a result of this transaction, our investor partner, Shanxi Aluminum Industrial Co., 
Ltd., became the largest shareholder and assumed the right to appoint the general manager and thereby exercised greater 
control over JiYa’s long-term strategic direction.  Further, although our Chief Executive Officer remains on the board, as of 
March 11, 2019 he was no longer the chairman of JiYa’s board of directors and our Chief Financial Officer was no longer a 
member of JiYa’s board of financial supervisors.  

Previously we accounted for JiYa’s financial performance under the consolidation method of accounting.  As a 

result of the changes we began to account for JiYa’s financial performance under the equity method of accounting.  
Therefore, we deconsolidated JiYa from our consolidated financial statements as of March 11, 2019 in accordance with 
ASC 810. As of March 12, 2019, we accounted for our investment in JiYa under the equity method of accounting as we 
continue to have board representation and substantial ownership.  Pro-forma financials have not been presented because we
believe the effects were not material to our consolidated financial position and results of operation for all periods presented.
JiYa continues to be a related party to us after deconsolidation, whom we may purchase raw materials from for production
in the ordinary course of business from time to time.

We  recorded  a  gain  on  the  deconsolidation  of  JiYa  of  $175,000  as  a  component  of  “Equity  in  loss  of
unconsolidated joint ventures” during 2019 in the consolidated statements of operations and comprehensive income (loss).

Table of Contents

On the date of deconsolidation, the fair value of the Company’s investment in JiYa exceeded the Company’s share of the
net assets of JiYa, which generated the gain. As of March 12, 2019, we recorded our investment in JiYa at a fair value of
$2,040,000, which was based on an independent third-party valuation analysis. The valuation is based on the asset-based
approach. The market-based approach is not deemed appropriate due to lack of availability of market data for comparable
companies on the open market and the discounted cash flow approach is not deemed reliable because of the difficulty in
predicting the future profitability of JiYa due to the volatility of the gallium market, the concentration of customers and the
significant  accumulated  losses  of  JiYa.  The  asset-based  approach  examines  the  value  of  a  company’s  assets  net  of  its
liabilities to derive a value for the equity holders. The gain on deconsolidation includes the following:

Fair value of the consideration received
Fair value of the retained investment in Beijing JiYa Semiconductor Material Co., Ltd.
Carrying value of noncontrolling interests, net of accumulated other comprehensive income attributable
to subsidiary
Derecognition of Beijing JiYa Semiconductor Material Co., Ltd.'s net asset
Gain recognized on deconsolidation of Beijing JiYa Semiconductor Material Co., Ltd.

Fair value of the retained investment in Beijing JiYa Semiconductor Material Co., Ltd.
Carrying value of retained noncontrolling investment
Gain on retained noncontrolling investment due to remeasurement

Before June 15, 2018, our ownership of JinMei was 83%. On June 15, 2018, we purchased a 12% ownership
interest from one of the minority owners of JinMei for $1.4 million. The $1.4 million was scheduled to be paid in two
installments. On June 15, 2018, we paid the first installment of $163,000. In May 2019, we paid the second installment of
$1.2 million as the relocation of JinMei’s headquarters and manufacturing operations was nearly complete, which had been
previously included in “Accrued liabilities” in our consolidated balance sheets. As a result, our ownership of JinMei
increased from 83% to 95%. In September 2018, we purchased a 2% ownership interest from one of the three remaining
minority owners of JinMei for $252,000. As a result, our ownership of JinMei increased from 95% to 97%. In May 2019,
we purchased the remaining 3% ownership interest from retiring members of the JinMei management team for
approximately $413,000. The final payment to the JinMei management team was made in October, 2020. As a result, our
ownership of JinMei increased from 97% to 100%. Prior to June 1, 2019, we reported JinMei as a consolidated joint
venture as we had a controlling financial interest and have majority control of the board. As of June 1, 2019, we referred to
it as a wholly-owned subsidiary and reduced the carrying value of the corresponding noncontrolling interests to zero.
Before August 1, 2020, our ownership of ChaoYang JinMei was 100%. In August 2020, we sold an 8.5% ownership
interest to current members of the ChaoYang JinMei management team for approximately $396,000. As a result, our
ownership of ChaoYang JinMei decreased from 100% to 91.5%. As of August 2020, we referred to ChaoYang JinMei as a
significantly controlled subsidiary instead of a wholly-owned subsidiary. Our Chief Executive Officer is chairman of the
JinMei board and we have appointed two other representatives to serve on the JinMei board.

Our ownership of BoYu is 67%. On November 2, 2017, BoYu raised additional capital in the amount of $2 million

in cash from a third-party investor through the issuance of shares equivalent to 10% ownership of BoYu. As a result, our
ownership of BoYu was diluted from 70% to 63%. In December 2020, we purchased shares equivalent to 4% of BoYu from
the same third-party investor for $1.6 million. As a result, our ownership of BoYu increased from 63% to 67%. We
continue to consolidate BoYu as we have a controlling financial interest and have majority control of the board and
accordingly no gain was recognized as a result of this equity transaction. Our Chief Executive Officer is chairman of the
BoYu board and we have appointed two other representatives to serve on the board.

An additional step in the STAR Market initial public offering (“IPO”) process involves certain entity 
reorganizations and alignment of assets under Tongmei.  In this regard our two consolidated raw material companies, 
JinMei and BoYu and its subsidiaries were assigned to Tongmei in December 2020.  This will increase the number of 
customers and employees attributable to Tongmei as well as increase Tongmei’s consolidated revenue.

Although we have representation on the boards of directors of each of these companies, the daily operations of
each of these companies are managed by local management and not by us. Decisions concerning their respective short-
term strategy and operations, ordinary course of business capital expenditures, and decisions concerning sales of finished
product, are made by local management with regular guidance and input from us.

During 2020, 2019 and 2018, our two consolidated raw material subsidiaries generated $7.5 million, $4.3 million
and $5.5 million of income, respectively, of which an income of $1.8 million, an income of $1.0 million and an income of
$1.4 million, respectively were allocated to noncontrolling interests, resulting in $5.7 million, $3.3 million and $4.1 million
of income, respectively, to our net income (loss).

For AXT’s minority investment entities that are not consolidated, the investment balances are included in “Other

assets” in our consolidated balance sheets and totaled $6.4 million and $6.0 million as of December 31, 2020 and 2019,
respectively. Our respective ownership interests in each of these companies are 46%, 39%, 25%, 25% and 25%. These
minority investment entities are not considered variable interest entities because:

● all minority investment entities have sustainable businesses of their own;

● our voting power is proportionate to our ownership interests;

● we only recognize our respective share of the losses and/or residual returns generated by the companies if they

occur; and

● we do not have controlling financial interest in, do not maintain operational or management control of, do not

control the board of directors of, and are not required to provide additional investment or financial support to any
of these companies.

One of the minority investment entities in which we have a 25% ownership interest is a germanium materials 

company in China.  This company provides results to us only on a quarterly basis.  We received its preliminary first quarter 
2019 financial results in early April 2019 as well as its projections for significant losses going forward. Such projected 
losses would fully deplete our asset investment balance for this company in 2019.  The Company is experiencing 
significant disruptions due to upgrades and repairs required to comply with stronger environmental regulations in China.  
As a result, we determined that this asset was fully impaired and wrote the asset balance down to zero.  This resulted in a 
$1.1 million impairment charge in our first quarter 2019 financial results.

AXT’s minority investment entities are not consolidated and are accounted for under the equity method.
Excluding one fully impaired entity, the equity entities had the following summarized income information (in thousands)

Note 8. Bank Loans and Line of Credit

On November 6, 2018, the Company entered into the Credit Agreement, which established a $10 million secured
revolving line of credit with a $1.0 million letter of credit sublimit facility. The revolving credit facility is collateralized by
substantially all of the assets of the Company located within the United States, subject to certain exceptions. The
commitments under the Credit Agreement expire on November 30, 2020 and any loans thereunder will bear interest at a
rate based on the daily one-month LIBOR for the applicable interest period plus a margin of 2%.  As of December 31,
2019, no loans or letters of credit were outstanding under the Credit Agreement. Effective February 5, 2020, the Company
amended the Credit Agreement. The line of credit was reduced from $10 million to $7 million. The commitments under the
First Amendment To Credit Agreement expired on November 30, 2020, no loans or letters of credit were outstanding under
the Credit Agreement at December 31, 2020.

On August 9, 2019, Tongmei entered into a credit facility with the Bank of China with a $5.8 million line of credit

at an annual interest rate of approximately 0.4% over the average interest rate quoted by the National Interbank Funding
Center. Accrued interest is calculated monthly and paid quarterly. The annual interest rate was approximately 4.7% as of
December 31, 2019. The credit facility is collateralized by Baoding Tongmei’s land use rights and all of its buildings
located at its facility in Dingxing. The primary intended use of the credit facility is for general purposes, which may
include working capital and other corporate expenses.

On August 9, 2019, we borrowed $2.8 million against the credit facility. The repayment of the full amount was
due on August 9, 2020. On September 12, 2019, we borrowed an additional $2.8 million against the credit facility. The
repayment of the full amount was due on September 12, 2020. In August 2020, Tongmei repaid the full amount of the
credit facility including all outstanding accrued interest of approximately $5.9 million and simultaneously applied to renew
the credit facility. The process of repaying a loan and then renewing the loan is customary in China.

In September 2020, the August 2019 borrowing was renewed and funded against the credit facility with an interest

rate of 3.85%. The interest owed during the term of the loan was deducted prior to funding. The repayment of the loan is
due on March 22, 2021, however the credit facility contains an option to renew for an additional six months.

 In October 2020, the September 2019 borrowing was renewed and funded against the credit facility and an 

additional $2.7 million was approved and funded against the credit facility with the annual interest rate of 4.7%. Accrued 
interest is calculated monthly and paid quarterly.  The combined loan totals $5.6 million. The repayment of the $5.6 million 
is due on April 8, 2021, however, the credit facility contains an option to renew for an additional six months. As of 
December 31, 2020, $8.9 million was included in “Bank loan” in our consolidated balance sheets.

In February 2020, our consolidated subsidiary, BoYu, entered into a credit facility with the Industrial and
Commercial Bank of China (“ICBC”) with a $1.4 million line of credit at an annual interest rate of approximately 0.15%
over the loan prime rate. Accrued interest is calculated monthly and paid quarterly. The annual interest rate was
approximately 4.3% as of December 31, 2020. The credit facility is collateralized by BoYu’s land use rights and its
building located at its facility in Tianjin, China and BoYu’s accounts receivable. The primary intended use of the credit
facility is for general purposes, which may include working capital and other corporate expenses.

In March 2020, BoYu borrowed $0.4 million against the credit facility. The repayment of the full amount is due in
March 2021. In December 2020, BoYu borrowed an additional $1.1 million against the credit facility.  As of December 31, 
2020, $1.5 million was included in “Bank loan” in our consolidated balance sheets.

On October 27, 2014, our Board of Directors approved a stock repurchase program pursuant to which we may

repurchase up to $5.0 million of our outstanding common stock.  These repurchases can be made from time to time in the
open market and are funded from our existing cash balances and cash generated from operations. During 2015, we
repurchased approximately 908,000 shares at an average price of $2.52 per share for a total purchase price
of approximately $2.3 million under the stock repurchase program. No shares were repurchased during 2020, 2019 and
2018 under this program. As of December 31, 2020, approximately $2.7 million remained available for future repurchases
under this program. 

By the terms of the Series A preferred stock, so long as any shares of Series A preferred stock are outstanding,

neither the Company nor any subsidiary of the Company shall redeem, repurchase or otherwise acquire any shares of
common stock, unless all accrued dividends on the Series A preferred stock have been paid. During 2013 and 2015, we
repurchased shares of our outstanding common stock.  As of December 31, 2015, the Series A preferred stock had
cumulative dividends of $2.9 million and we included this amount in “Accrued liabilities” in our consolidated balance
sheets. In 2018, 2019 and 2020, we did not repurchase any of our outstanding common stock. If we are required to pay the
cumulative dividends on the Series A preferred stock, our cash and cash equivalents would be reduced.  We account for the
cumulative year to date dividends on the Series A preferred stock when calculating our earnings per share.

Note 10. Employee Benefit Plans and Stock-based Compensation

Stock Option Plans and Equity Incentive Plans

In May 2007, our stockholders approved our 2007 Equity Incentive Plan (the “2007 Plan”), which provides for the

grant of incentive and non-qualified stock options to our employees, consultants and directors. The 2007 Plan is a
restatement of the 1997 Stock Option Plan which expired in 2007. The 1,928,994 share reserve of the 1997 Stock Option
Plan became the reserve of the 2007 Plan, together with 1,300,000 additional shares approved for issuance under the 2007
Plan. In May 2013, the stockholders approved an additional 2,000,000 shares to be issued under the 2007 plan. Awards
may be made under the 2007 Plan are stock options, stock appreciation rights, restricted stock, restricted stock units,
performance shares, performance units, deferred compensation awards and other stock-based awards. Stock options and
stock appreciation rights awarded under the 2007 Plan may not be repriced without stockholder approval. Stock options
and stock appreciation rights may not be granted below fair market value. Stock options or stock

93

    
 
 
 
 
Table of Contents

appreciation rights generally shall not be fully vested over a period of less than three years from the date of grant and 
cannot be exercised more than 10 years from the date of grant. Restricted stock, restricted stock units, and performance 
awards generally shall not vest faster than over a three-year period (or a twelve-month period if vesting is based on a 
performance measure). In December 2008, the 2007 Plan was amended to comply with the applicable requirements under 
Section 409A of the Internal Revenue Code. 

In May 2015, our stockholders approved our 2015 Equity Incentive Plan (the “2015 Plan”). The 2015 Plan is a
replacement of the 2007 Plan. The 399,562 share reserve of the 2007 Plan became the reserve of the 2015 Plan, together
with 3,000,000 additional shares approved for issuance under the 2015 Plan. In May 2019, our stockholders approved
1,600,000 of additional shares for issuance under the 2015 Plan. Awards that may be made under the 2015 Plan are stock
options, stock appreciation rights, restricted stock, restricted stock units, performance shares, performance units, deferred
compensation awards and other stock-based awards. Stock options and stock appreciation rights awarded under the 2015
Plan may not be repriced without stockholder approval. Stock options and stock appreciation rights may not be granted
below fair market value. Stock options or stock appreciation rights generally shall not be fully vested over a period of less
than four years from the date of grant and cannot be exercised more than 10 years from the date of grant. Restricted stock, 
restricted stock units, and performance awards generally shall not vest faster than over a three-year period (or a twelve-
month period if vesting is based on a performance measure). However, options granted to consultants and restricted stock 
awards granted to independent board members typically vest in one year and the 2015 Plan does allow for similar vesting 
to employees.  As of December 31, 2020, approximately 0.6 million shares were available for grant under the 2015 Plan.

There were 905,000, 113,000 and 238,000 options exercised in the years ended December 31, 2020, 2019 and

2018, respectively. The total intrinsic value of options exercised for the years ended December 31, 2020, 2019 and 2018,
was $3.2 million, $266,000 and $666,000, respectively.

As of December 31, 2020, the unamortized compensation costs related to unvested stock options granted to

employees under our 2015 plan was approximately $0.8 million, net of estimated forfeitures of $71,000. These costs will
be amortized on a straight-line basis over a weighted-average period of approximately 2.4 years and will be adjusted for 
subsequent changes in estimated forfeitures. We did not capitalize any stock-based compensation to inventory as of 
December 31, 2020 and 2019, as the amount was insignificant.

We estimate the fair value of stock options using a Black-Scholes option pricing model. There were no stock

options granted during 2020. There were 430,000 and 246,000 stock options granted with a weighted-average grant date
fair value of $1.48 and $2.74 per share during 2019 and 2018, respectively. The fair value of options granted was estimated
at the date of grant using the following weighted-average assumptions:

Expected term (in years)
Volatility
Expected dividend
Risk-free interest rate

The expected term for stock options is based on the observed historical option exercise behavior and post-vesting

forfeitures of options by our employees, and the contractual term, the vesting period and the expected term of the
outstanding options. Expected volatility is based on the historical volatility of our common stock. The dividend yield of
zero is based on the fact that we have never paid cash dividends and have no present intention to pay cash dividends. The
risk-free interest rates are taken from the Daily Federal Yield Curve Rates as of the grant dates as published by the Federal
Reserve and represent the yields on actively traded Treasury securities for terms equal to the expected term of the options.

Retirement Savings Plan

We have a 401(k) Savings Plan (“Savings Plan”) which qualifies as a thrift plan under Section 401(k) of the

Internal Revenue Code. All full-time U.S. employees are eligible to participate in the Savings Plan after 90 days from the
date of hire. Employees may elect to reduce their current compensation by up to the statutory prescribed annual limit and
have the amount of such reduction contributed to the 401(k) Plan. We provide matching to employee contributions up to
4% of the employees’ base pay if employees contribute at least 6% of their base pay. If the contribution rate is less than 6%
of the base pay, the matching percentage is prorated. Our contributions to the Savings Plan were $188,000, $176,000 and
$180,000 for the years ended December 31, 2020, 2019 and 2018, respectively.

Note 11. Guarantees

Indemnification Agreements

We have entered into indemnification agreements with our directors and officers that require us to indemnify our
directors and officers against liabilities that may arise by reason of their status or service as directors or officers, other than
liabilities arising from willful misconduct of a culpable nature; to advance their expenses incurred as a result of any
proceeding against them as to which they could be indemnified; and to obtain directors’ and officers’ insurance if available
on reasonable terms, which we currently have in place.

Product Warranty

We provide warranties for our products for a specific period of time, generally twelve months, against material

defects. We provide for the estimated future costs of warranty obligations in cost of sales when the related revenue is
recognized. The accrued warranty costs represent the best estimate at the time of sale of the total costs that we expect to
incur to repair or replace product parts that fail while still under warranty. The amount of accrued estimated warranty costs
are primarily based on historical experience as to product failures as well as current information on repair costs. On a
quarterly basis, we review the accrued balances and update the historical warranty cost trends. The following table reflects
the change in our warranty accrual which is included in “Accrued liabilities” on the consolidated balance sheets, during
2020 and 2019 (in thousands):

Beginning accrued product warranty
Accruals for warranties issued
Adjustments related to pre-existing warranties including expirations and changes in
estimates

As of December 31, 2020, we have federal net operating loss (“NOL”) carryforwards of approximately
$57.0 million, which will begin to expire in 2024. In addition, we have federal tax credit carryforwards of approximately
$0.8 million, which will begin to expire in 2021. We have utilized all state net operating losses, primarily in the state of
California, as of December 31, 2020.

 The deferred tax assets valuation allowance as of December 31, 2020 is attributed to U.S. federal, and state 

deferred tax assets, which result primarily from future deductible accruals, reserves, NOL carryforwards, and tax credit 
carryforwards. We believe that, based on a number of factors, the available objective evidence creates sufficient uncertainty 
regarding the realizability of the deferred tax assets such that a full valuation allowance has been recorded. These factors 
include our history of losses related to domestic operations, and the lack of carryback capacity to realize deferred tax 
assets. The valuation allowance increased by $0.1 million and $0.2 million for the years ended December 31, 2020 and 
2019, respectively, whereas the valuation allowance decreased by $2.6 million for the year ended December 31, 2018.

The China Enterprise Income Tax Law (“EIT”) imposes a single uniform income tax rate of 25% on all Chinese

enterprises.  Our subsidiaries in China have qualified for a preferential 15% tax rate that is available for High and New
Technology Enterprises (“HTE”).  In order to retain the preferential tax rate, we must meet certain operating conditions,
satisfy certain product requirements, meet certain headcount requirements and maintain certain levels of research
expenditures. We realized benefits from this 10% reduction in tax rate of $973,000, $211,000 and $764,000 for 2020, 2019
and 2018, respectively. As of December 31, 2020, the favorable tax rate is still valid for the Company and it will stay the
same for next year if there is no change of the business nature. The preferential tax rate that we enjoy could be modified or
discontinued altogether at any time, which could materially and adversely affect our financial condition and results of
operations.

Our subsidiaries in China also qualify for reduction in their taxable income in China for research and development
(“R&D”) expenditures. Government pre-approval is required to claim R&D tax benefits. Any R&D claim is then submitted
with the annual corporate income tax for the taxing authorities’ approval. Historically, we didn’t record such benefit until
we received the tax refund from the Chinese government. Beginning in 2019, we record the tax benefit in the year it incurs
the cost rather than in the year the tax benefit is received. This will better align the costs with the tax benefit. Our
consolidated subsidiaries in China have enjoyed various tax holidays since 2000. Benefits under the tax holidays vary by
jurisdiction.

Utilization of the NOL and R&D credit carryforwards may be subject to a substantial annual limitation due to

ownership changes that might have occurred previously or that could occur in the future, as provided by Section 382 of the
Internal Revenue Code of 1986 (“Section 382”), as well as similar state provisions. Ownership changes may limit the
amount of NOL and tax credit carryforwards that can be utilized to offset future taxable income and tax, respectively. In
general, an ownership change, as defined by Section 382, results from transactions increasing the ownership of certain
shareholders or public groups in the stock of a corporation by more than 50 percentage points over a three-year period. If
there is a change of control, utilization of our NOL or tax credit carryforwards would be subject to an annual limitation
under Section 382. Any limitation may result in expiration of a portion of the NOL or research and development credit
carryforwards before utilization. Subsequent ownership changes could further impact the limitation in future years. Until a
Section 382 study is completed and any limitation known, no amounts are being presented as an uncertain tax position. A
full valuation allowance has been provided against our NOL carryforwards and R&D credit carryforwards and, if an
adjustment is required, this adjustment would be offset by an adjustment to the valuation allowance. Thus, there would be
no net impact to the consolidated balance sheets or statements of operations if an adjustment were required.

During fiscal year 2020, 2019 and 2018, the amount of gross unrecognized tax benefits remains unchanged. The

total amount of unrecognized tax benefits was $14.6 million as of December 31, 2020 and 2019. The Company recognizes
interest and penalties related to uncertain tax positions as part of the provision for income taxes. To date, such interest and
penalties have not been material. Excluding the effects of recorded valuation allowances for deferred tax assets,
$14.6 million of the unrecognized tax benefit would favorably impact the effective tax rate in future periods if recognized.

We comply with the laws, regulations, and filing requirements of all jurisdictions in which we conduct business.

We regularly engage in discussions and negotiations with tax authorities regarding tax matters in various jurisdictions.

We file income tax returns in the U.S. federal, various states and foreign jurisdictions. Currently, there is no tax

audit in any of the jurisdictions and we do not expect there will be any significant change to this.

On June 29, 2020, Governor Newsom signed the highly anticipated budget package for California’s fiscal year

that began on July 1, 2020. As part of the budget package, Assembly Bill 85 (“AB 85”) was enacted into law. The bill
contains several tax changes to help with the budget deficit. Notably, AB 85 contains two major tax changes: (1) it
suspends the usage of NOLs; and (2) it limits certain business tax credits for tax years 2020, 2021, and 2022. The budget
has no impact to the Company since the Company has no NOLs and business credits to utilize.

On Sunday, December 27, 2020, a new $900 billion Coronavirus relief bill was signed into law by the President.
The bill includes updates to the Families First Coronavirus Act, CARES Act, the Employee Social Security Deferral and
the Paycheck Protection Program. Since the Company has no taxable income, most of the acts have no direct impact or are
not applicable to the Company.

Note 13. Net Income (Loss) per Share

Basic net income (loss) per share is computed using the weighted average number of common shares outstanding

during the periods less shares of common stock subject to repurchase and non-vested stock awards. Diluted net income
(loss) per share is computed using the weighted-average number of common shares outstanding and potentially dilutive
common shares outstanding during the periods. The dilutive effect of outstanding stock options and restricted stock awards
is reflected in diluted earnings per share by application of the treasury stock method. Potentially dilutive common shares
consist of common shares issuable upon the exercise of stock options. Potentially dilutive common shares are excluded in
net loss periods, as their effect would be anti-dilutive.

A reconciliation of the numerators and denominators of the basic and diluted net income (loss) per share

calculations is as follows (in thousands, except per share data):

Note 16. Commitments and Contingencies

Legal Proceedings

From time to time we may be involved in judicial or administrative proceedings concerning matters arising in the

ordinary course of business. We do not expect that any of these matters, individually or in the aggregate, will have a
material adverse effect on our business, financial condition, cash flows or results of operations.

Leases

We lease certain equipment, office space, warehouse and facilities under long-term operating leases expiring at

various dates through July 2029. The majority of our lease obligations relate to our lease agreement for a nitrogen system
to be used during the manufacturing process for our facility in Dingxing, China. The equipment lease became effective in
August 2019 and will expire in July 2029. There are no variable lease payments, residual value guarantees or any
restrictions or covenants imposed by the equipment lease. The remainder relate to our lease agreement for our facility in
Fremont, California with approximately 19,467 square feet, which expires in 2020. Under the terms of the facility lease
agreement, in May 2020, we were granted an extension to the term of the lease for an additional three years. There are no
variable lease payments, residual value guarantees or any restrictions or covenants imposed by the facility lease. All other
operating leases have a term of 12 months or less.

Leases are classified as either finance leases or operating leases. A lease is classified as a finance lease if any one
of the following criteria are met: the lease transfers ownership of the asset by the end of the lease term, the lease contains
an option to purchase the asset that is reasonably certain to be exercised, the lease term is for a major part of the remaining
useful life of the asset or the present value of the lease payments equals or exceeds substantially all of the fair value of the
asset. A lease is classified as an operating lease if it does not meet any one of these criteria. All of our leases are classified
as operating leases and substantially all of our operating leases are comprised of equipment and office space leases. None
of our leases are classified as, finance leases.

For all leases at the lease commencement date, a right-of-use asset and a lease liability are recognized. The right-
of-use asset represents the right to use the leased asset for the lease term. The lease liability represents the present value of
the lease payments under the lease.

The right-of-use asset is initially measured at cost, which primarily comprises the initial amount of the lease
liability, plus any initial direct costs incurred, consisting mainly of brokerage commissions, less any lease incentives
received. All right-of-use assets are reviewed for impairment. The lease liability is initially measured at the present value of
the lease payments, discounted using the interest rate implicit in the lease or, if that rate cannot be readily determined, our
secured incremental borrowing rate for the same term as the underlying lease.

Lease payments included in the measurement of the lease liability comprise the following: the fixed noncancelable

lease payments, payments for optional renewal periods where it is reasonably certain the renewal period

102

    
    
Table of Contents

will be exercised, and payments for early termination options unless it is reasonably certain the lease will not be terminated
early.

Lease expense for operating leases consists of the lease payments plus any initial direct costs, primarily brokerage

commissions, and is recognized on a straight-line basis over the lease term.

We have elected not to recognize right-of-use assets and lease liabilities for short-term leases that have a term of

12 months or less. The effect of short-term leases on our right-of-use asset and lease liability was not material.

As of December 31, 2020, the maturities of our operating lease liabilities (excluding short-term leases) are as

follows (in thousands):

In 2010, we and a competitor had entered into a royalty agreement with a term of eight years, terminating 
December 31, 2018.  We were obligated to make annual payments over an eight-year period. For the year ended December
31, 2018, royalty expense under this agreement was $565,000, which was net of claim for credit of $10,000. These
expenses were included in cost of revenue.

In 2020, we and a competitor entered into a cross license and covenant agreement (the “Cross License 
Agreement”), which has a term that began on January 1, 2020 and expires on December 31, 2029.  The Cross License 
Agreement is a fixed-cost cross license and not a variable-cost cross license that is based on revenue or units. Under the 
Cross License Agreement, we are obligated to make annual payments over a 10-year period. For the year ended December
31, 2020, royalty expense under this agreement was $174,000.

Land Purchase and Investment Agreement

We have established a wafer process production line in Dingxing, China. In addition to a land rights and building
purchase agreement that we entered into with a private real estate development company to acquire our new manufacturing
facility, we also entered into a cooperation agreement with the Dingxing local government. In addition to pledging its full
support and cooperation, the Dingxing local government will issue certain credits or rebates to us as we achieve certain
milestones.  We, in turn, agreed to hire local workers over time, pay taxes when due and eventually demonstrate a total
investment of approximately $90 million in value, assets and capital. The investment will include cash paid for the land
and buildings, cash on deposit in our name at local banks, the gross value of new and used equipment (including future
equipment  that  might  be  used  for  indium  phosphide  and  germanium  substrates  production),  the  deemed  value  for  our
customer list or the end user of our substrates, for example, the end users of 3-D sensing VCSELs (vertical cavity surface
emitting lasers), a deemed value for employment of local citizens, a deemed value for our proprietary process technology,
other intellectual property, other intangibles and additional items of value. There is no timeline or deadline by which this
must be accomplished, rather it is a good faith covenant entered into between AXT and the Dingxing local government.
Further,  there  is  no  specific  penalty  contemplated  if  either  party  breaches  the  agreement.  However,  the  agreement  does
state  that  each  party  has  a  right  to  seek  from  the  other  party  compensation  for  losses.  Under  certain  conditions,  the
Dingxing local government may purchase the land and building at the appraised value. We believe that such cooperation
agreements are normal, customary and usual in China and that the future valuation is flexible. We have a similar agreement
with  the  city  of  Kazuo,  China,  although  on  a  smaller  scale.  The  total  investment  targeted  by  AXT  in  Kazuo  is
approximately $15 million in value, assets and capital. In addition, BoYu has a similar agreement with the city of Kazuo.
The total investment targeted by BoYu in Kazuo is approximately $8 million in value, assets and capital.

As discussed in Note 1, during the quarter ended December 31, 2020, Tongmei entered into the Capital
Investment Agreements with private equity funds that invested approximately $48.1 million in the form of redeemable
noncontrolling interests representing 7.06% of the outstanding shares of Tongmei. The initial carrying amount of the
redeemable noncontrolling interests was recorded at fair value on the date of issuance of Tongmei’s common stock, net of
issuance costs and presented in temporary equity on the consolidated balance sheets. This classification is due to the
existence of certain contingencies that could result in potential redemption at the fixed purchase price as described below.
We currently do not believe that this is probable thus no accretion of the issuance costs has been recorded.

Pursuant to the Capital Investment Agreements with the Investors, each Investor has the right to require AXT to

redeem any or all Tongmei shares held by such Investor at the original purchase price paid by such Investor, without
interest, in the event of a material adverse change or if Tongmei does not achieve its IPO on or before December 31, 2022.
This right is suspended when Tongmei submits its formal application to the China Securities Regulatory Commission
(“CSRC”). Tongmei currently plans to submit its formal application to the CSRC in the third quarter of 2021. However, if
on December 31, 2022 the IPO application has been submitted and accepted by the CSRC or the stock exchange and such
submission remains under review, then the date when such Investor is entitled to exercise such redemption right shall be
deferred to a date when such submission is rejected by the CSRC or stock exchange, or the date when Tongmei withdraws
its IPO application. The process of going public on the STAR Market includes several periods of review and is therefore a
lengthy process. Tongmei does not expect to complete the IPO until mid-2022. The listing of Tongmei on China’s STAR
Market will not change the status of AXT as a U.S. public company. There can be no assurances that Tongmei will
complete its IPO by December 31, 2022, or at all. In the event that Investors exercise their redemption rights, we may be
required to seek additional capital in order to redeem their Tongmei shares and there would be no assurances that such
capital would be available on terms acceptable to us, if at all. Any redemptions could have a material adverse effect on our
business, financial condition and results of operations.

The components of the change in redeemable noncontrolling interests for the year ended December 31, 2020 are

presented in the following table (in thousands):

Note 19. Subsequent Events

In 2020, the private equity funds had transferred approximately $48.1 million of new capital to Tongmei. An

additional investment of approximately $1.5 million of new capital was funded in early January 2021. Under China
regulations these investments must be formally approved by the appropriate government agency and are not deemed to be
dilutive until such approval is granted. The government approved the entire approximately $49 million investment on
January 25, 2021 at which time the private equity funds owned a minority interest in Tongmei of 7.28%.

In January 2021, we purchased 0.55% shares of Tongmei from Beijing Bomeilian Special Ceramics Co., Ltd.,

previously a minority interest shareholder of BoYu, for $3.73 million. As a result of this purchase, and of the government’s
approval January 25, 2021 of the private equity funds we now own 85.5% of Tongmei.

In February 2021, Tongmei signed a joint venture agreement with certain investors to fund a new company,

ChaoYang XinMei High Purity Semiconductor Materials Co., Ltd. (“ChaoYang XinMei”). The agreement calls for a total
investment of approximately $3 million in which Tongmei will fund approximately $1.8 million for a 58.5 percent
ownership of ChaoYang XinMei. In February 2021, the investors completed the initial funding of approximately $1.5
million. Tongmei’s portion of the investment was approximately $0.9 million.

DESCRIPTION OF THE REGISTRANT’S SECURITIES
REGISTERED PURSUANT TO SECTION 12 OF THE
SECURITIES EXCHANGE ACT OF 1934

DESCRIPTION OF CAPITAL STOCK

Exhibit 4.1

The following information describes our common stock and preferred stock, as well as certain provisions of our

restated certificate of incorporation, as amended (the “certificate of incorporation”), and second amended and restated
bylaws, as amended (the “bylaws”). This summary does not purport to be complete and is qualified in its entirety by the
provisions of our certificate of incorporation and bylaws, copies of which have been filed as exhibits to this Annual Report
on Form 10-K, as well as to the applicable provisions of the Delaware General Corporation Law.

General

Our authorized capital stock consists of 70,000,000 shares of common stock with a $0.001 par value per share (the

“common stock”) and 2,000,000 shares of preferred stock with a $0.001 par value per share (the “preferred stock”),
1,000,000 shares of which are designated as “Series A Preferred Stock” and 200,000 of which are designated as “Series B
Preferred Stock.” Our board of directors may establish the rights and preferences of the preferred stock from time to time.

Common Stock

Each holder of our common stock is entitled to one vote for each share on all matters to be voted upon by the

stockholders. Subject to any preferential rights of any outstanding preferred stock, holders of our common stock are entitled
to receive ratably the dividends, if any, as may be declared from time to time by the board of directors out of funds legally
available therefor. We have never declared or paid any cash dividend on our capital stock and do not anticipate paying any
cash dividends in the foreseeable future. If there is a liquidation, dissolution or winding up of our company, holders of our
common stock would be entitled to share ratably in our assets remaining after the payment of liabilities and any preferential
rights of any outstanding preferred stock.

Holders of our common stock have no preemptive or conversion rights or other subscription rights, and there are

no redemption or sinking fund provisions applicable to the common stock. The outstanding shares of common stock are
fully paid and non-assessable. The rights, preferences and privileges of the holders of our common stock are subject to, and
may be adversely affected by, the rights of the holders of shares of any series of preferred stock that we may designate and
issue in the future.

Our common stock is listed on the NASDAQ Global Select Market under the symbol “AXTI.” The transfer agent

and registrar for the common stock is Broadridge Corporate Issuer Solutions, Inc.

Preferred Stock

Our certificate of incorporation provides that we may issue up to 2,000,000 shares of preferred stock. As of March

23, 2021, 883,000 shares of our Series A Preferred Stock were issued and outstanding and are non-voting and non-
convertible preferred stock with a 5.0% cumulative annual dividend rate payable when declared by the board of directors
and $4 per share liquidation preference over common stock, and must be paid before any distribution is made to common
stockholders. Other than the Series A Preferred Stock, no shares of preferred stock are currently outstanding.

Under the terms of our certificate of incorporation, our board of directors is authorized to issue shares of preferred
stock in one or more series without stockholder approval. Our board of directors has the discretion to determine the rights,
preferences, privileges and restrictions, including voting rights, dividend rights, conversion rights, redemption privileges
and liquidation preferences, of each series of preferred stock. There are no restrictions presently on the repurchase or
redemption of any shares of our preferred stock.

The issuance of shares of preferred stock will affect, and may adversely affect, the rights of holders of common

stock. It is not possible to state the actual effect of the issuance of any shares of preferred stock on the rights of holders

of common stock until our board of directors determines the specific rights attached to that preferred stock. The effects of
issuing additional preferred stock could include one or more of the following:

● restricting dividends on the common stock;
● diluting the voting power of the common stock;
● impairing the liquidation rights of the common stock; or
● delaying or preventing changes in control or management of our company.

Preferred stock will be fully paid and nonassessable upon issuance.

Effect of Certain Provisions of our Certificate of Incorporation and Bylaws and the Delaware Anti-Takeover Statute

Some provisions of Delaware law and our certificate of incorporation and bylaws contain provisions that could

make the following transactions more difficult:

● acquisition of us by means of a tender offer;
● acquisition of us by means of a proxy contest or otherwise; or
● removal of our incumbent officers and directors.

Those provisions, summarized below, are expected to discourage coercive takeover practices and inadequate

takeover bids and to promote stability in our management. These provisions are also designed to encourage persons seeking
to acquire control of us to first negotiate with our board of directors.

Certificate of Incorporation and Bylaws

Our certificate of incorporation and our bylaws provide for, among other things, the following:

● Undesignated Preferred Stock.  The ability to authorize undesignated preferred stock makes it possible for our 
board of directors to issue one or more series of preferred stock with voting or other rights or preferences that 
could impede the success of any attempt to change control of our company. These and other provisions may 
have the effect of deferring hostile takeovers or delaying changes in control or management of our company.

● Stockholder Meetings.  Our bylaws provide that in general a special meeting of stockholders may be called 

only by our board of directors, its chairman or our president.

● Requirements for Advance Notification of Stockholder Nominations and Proposals.  Our bylaws establish 

advance notice procedures with respect to stockholder proposals and the nomination of candidates for election 
as directors, other than nominations made by or at the direction of our board of directors or a committee of 
the board of directors.

● Board Classification.  Our board of directors is divided into three classes. The directors in each class are 

elected to serve for a three-year term, one class being elected each year by our stockholders. This system of 
electing and removing directors may tend to discourage a third party from making a tender offer or otherwise 
attempting to obtain control of us, because it generally makes it more difficult and time consuming for 
stockholders to replace a majority of the directors.

● Limits on Ability of Stockholders to Act by Written Consent.  We have provided in our bylaws that our 

stockholders may not act by written consent. This limit on the ability of our stockholders to act by written 
consent may lengthen the amount of time required to take stockholder actions. As a result, a holder 
controlling a majority of our capital stock would not be able to amend our bylaws or remove directors without 
holding a meeting of our stockholders called in accordance with our bylaws.

● Amendment of Certificate of Incorporation and Bylaws.  The amendment of the above provisions of our 

certificate of incorporation and bylaws requires approval by holders of at least two-thirds of our outstanding 
capital stock entitled to vote generally in the election of directors.

● Election and Removal of Directors.  Our certificate of incorporation and bylaws contain provisions that 
establish specific procedures for appointing and removing members of our board of directors. Under our 
certificate of incorporation and bylaws, vacancies and newly created directorships on our board of directors 
may be filled only by a majority of the directors then serving on the board of directors. Under our certificate 
of incorporation and bylaws, directors may be removed, with or without cause, by the affirmative vote of the 
holders of a majority of the shares then entitled to vote at an election of directors.

● No Cumulative Voting.  The Delaware General Corporation Law provides that stockholders are not entitled to 

the right to cumulate votes in the election of directors unless our certificate of incorporation provides 
otherwise. Our certificate of incorporation and bylaws do not expressly provide for cumulative voting. 
Without cumulative voting, a minority stockholder may not be able to gain as many seats on our board of 
directors as the stockholder would be able to gain if cumulative voting were permitted. The absence of 
cumulative voting makes it more difficult for a minority stockholder to gain a seat on our board of directors to 
influence our board of directors’ decision regarding a takeover.

Delaware Anti-Takeover Statute

We are subject to the provisions of Section 203 of the Delaware General Corporation Law regulating corporate

takeovers. In general, Section 203 prohibits a publicly-held Delaware corporation from engaging, under certain
circumstances, in a business combination with an interested stockholder for a period of three years following the date the
person became an interested stockholder unless:

● prior to the date of the transaction, the board of directors of the corporation approved either the business
combination or the transaction which resulted in the stockholder becoming an interested stockholder;
● upon completion of the transaction that resulted in the stockholder becoming an interested stockholder, the
interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the
transaction commenced, excluding for purposes of determining the voting stock outstanding, but not for
determining the outstanding voting stock owned by the interested stockholder, (i) shares owned by persons
who are directors and also officers, and (ii) shares owned by employee stock plans in which employee
participants do not have the right to determine confidentially whether shares held subject to the plan will be
tendered in a tender or exchange offer; or

● at or subsequent to the date of the transaction, the business combination is approved by the board of directors
of the corporation and authorized at an annual or special meeting of stockholders, and not by written consent,
by the affirmative vote of at least 66-2/3% of the outstanding voting stock which is not owned by the
interested stockholder.

Generally, a business combination includes a merger, asset or stock sale, or other transaction resulting in a
financial benefit to the interested stockholder. An interested stockholder is a person who, together with affiliates and
associates, owns or, within three years prior to the determination of interested stockholder status, did own 15% or more of a
corporation’s outstanding voting stock.

FIRST AMENDMENT TO CREDIT AGREEMENT AND WAIVER

Exhibit 10.12

This FIRST AMENDMENT TO CREDIT AGREEMENT AND WAIVER (this "Amendment"), dated as of February 5, 2020, is
entered  into  by  and  between  AXT,  INC.,  a  Delaware  corporation  ("Borrower"),  and  WELLS  FARGO  BANK,  NATIONAL

RECITALS

WHEREAS  Borrower  is  currently  indebted  to  Bank  pursuant  to  the  terms  and  conditions  of  that  certain  Credit  Agreement
between Borrower and Bank, dated as of November 2, 2018 (as amended from time to time, the "Credit Agreement").  Each capitalized
term used but not otherwise defined herein has the meaning ascribed thereto in the Credit Agreement.

WHEREAS  Borrower  has  informed  Bank  that  it  has  failed  to  maintain  its  financial  condition  as  of  September  30,  2019,
pursuant  to  the  terms  of  Section  4.9.(a)  of  the  Credit  Agreement,  and  that  such  failure  has  resulted  in  an  Event  of  Default  under  to
Section  6.1.(c)  of  the  Credit  Agreement  (the  “Profitability  Default”  and,  together  with  all  other  Events  of  Default  under  the  Credit
Agreement resulting therefrom, the “Specified Defaults”).

WHEREAS, on and subject to the terms and conditions of this Agreement:  (a) Borrower has requested that Bank waive the
Specified Defaults and agree to certain changes in the terms and conditions set forth in the Credit Agreement; and (b) Bank has agreed to
Borrower's requests.

NOW,  THEREFORE,  for  valuable  consideration,  the  receipt  and  sufficiency  of  which  are  hereby  acknowledged,  the  parties
hereto agree that the Credit Agreement and the other Loan Documents, as applicable, shall be amended and the parties hereto agree as
follows, provided that nothing contained herein shall terminate any security interests, guaranties, subordination or other documents in
favor of Bank, all of which shall remain in full force and effect unless otherwise expressly provided herein:

1.

Borrower  acknowledges  that  each  of  the  Specified  Defaults  constitutes  an  Event  of  Default  under  the  Credit
Agreement.  Pursuant to the request of Borrower and subject to the terms and conditions of this Amendment, Bank hereby waives the
Specified  Defaults.    The  limited  waiver  set  forth  in  this  Section  1  shall  be  limited  precisely  as  written  and  shall  not  be  deemed  to
constitute: (a) an amendment, consent or waiver of any other terms or conditions of the Credit Agreement or any other document related
to the Credit Agreement; or (b) a consent to any future amendment, consent or waiver, whether of any subsequent breach of the same
provisions or otherwise.  Except as expressly set forth in this Amendment, the Credit Agreement and each other document executed and
delivered in connection with the Credit Agreement shall continue in full force and effect.

2.

Section 1.1.(a) of the Credit Agreement is hereby deleted in its entirety and replaced with the following:

Line of Credit.  Subject to the terms and conditions of this Agreement, Bank hereby agrees to make
advances  to  Borrower  from  time  to  time  up  to  and  including  November  30,  2020,  not  to  exceed  at  any  time  the
aggregate principal amount of Seven Million Dollars ($7,000,000.00) (“Line of Credit”), the proceeds of which shall
be used for Borrower’s working capital requirements and other general corporate purposes.  Borrower’s obligation to
repay advances under the Line of Credit shall be evidenced by a promissory note dated as of November 2, 2018 (as the
same  may  be  amended,  supplemented  and/or  otherwise  modified  from  time  to  time,  the  “Line  of  Credit  Note”),  all
terms of which are incorporated

herein by this reference.

(0.375%) per annum (computed on the basis of a 360-day year, actual days elapsed) on the daily unused amount of the
Line of Credit, which fee shall be calculated on a quarterly basis by Bank and shall be due and payable by Borrower in
arrears on the fifteenth (15th) day of each fiscal quarter during the term hereof and on the maturity date hereof.

SECTION 2.1.

LEGAL STATUS.  (a) Borrower is a corporation, duly organized and existing and in good
standing under the laws of Delaware, and is qualified or licensed to do business (and is in good standing as a foreign

Borrowing  Group  (as  defined  below)  is  a  Sanctioned  Target  (as  defined  below)  of  economic  or  financial  sanctions,

otherwise  encumbered  any  of  its  assets  or  properties  except  in  favor  of  Bank  or  as  otherwise  permitted  by  Bank  in
writing.  All information provided from time to time by Borrower or any Third Party Obligor to Bank for the purpose

contract, tort, warranty, mistake or any other theory, whether legal, statutory or equitable; and (iii) any attempt to assert
a  Released  Claim  barred  by  the  provisions  of  this  General  Release  shall  subject  Borrower  to  the  provisions  of

RMB  1  registered  capital  price  corresponding  to  the  capital  increase  this  time)  is  not  subject  to  the  aforesaid
preemptive right. Party A agrees to waive the preemptive right.

9.3 Priority right to sell

In  the  case  that  the  controlling  shareholder,  as  the  transferring  shareholder,  plans  to  transfer  the  corporate
equity  held  by  it  to  a  third  party  (hereinafter  referred  to  as  the  “transferee”)  other  than  the  rest  shareholders
(except  for  transferring  the  corporate  equity  held  by  it  incurred  by  the  execution  of  the  Company's  employee
incentive  plan),  and  Party  A  does  not  exercise  the  preemptive  right  as  indicated  in  Article  9.2  of  the
Supplementary Agreement, Party A shall be entitled to send a written notice (hereinafter referred to as the “notice
of  priority  right  to  sell”)  to  the  controlling  shareholder  within  twenty  (20)  working  days  upon  receipt  of  the
transfer notice, requiring to sell the Company’s equities that Party A holds at the date thereof to a third  party in
priority  at  the  same  price  and  under  the  same  terms  and  conditions  as  those  of  the  controlling  shareholder's
transfer of equity to a third  party (hereinafter referred to as “the priority right to sell”), and specify the proportion
of  the  equity  to  be  transferred  to  the  registered  capital  in  the  notice  of  priority  right  to  sell.  In  such  case,  the
controlling shareholder shall promote the third party’s agreement on the acceptance of Party A’s equities.

In the event that Party A fails to issue a notice of priority right to sell within the above time limit, or exercises
the preemptive right pursuant to Article 9.2 of the Supplementary Agreement, it shall be deemed that Party A has
waived exercising the priority right to sell.

(1) Dividends accrue on our outstanding Series A preferred stock at the rate of $0.20 per annum per share of Series A preferred 

stock. We have not paid any dividends on preferred stock.  883,000 shares of our preferred stock were issued and outstanding 
for all of the periods presented.

(2) Effective January 1, 2019 and onwards, interest is calculated consistent with guidance under ASC 842, where an estimate for the

Company's incremental borrowing rate of 4.6% is used to calculate the interest component of rent expense. The borrowing rate
is calculated using a weighted average for the interest rate on the Company's revolving line of credit of 4.4% and credit facility
with the Bank of China of 4.7%. For the years prior to 2019, represents one-third of total rent expense which we believe is a
reasonable estimate of the interest component of rent expense.

(3) For periods in which there is a deficiency of earnings available to cover combined fixed charges and preferred stock dividends,

the ratio information is not applicable.
