To Our Shareholders

2021 was a remarkable year of transformation 
for Silicon Labs as we celebrated our 25th anni-
versary and placed the Internet of Things firmly 
at the center of our mission. We successfully 
executed the divestiture of the Infrastructure & 
Automotive business unit to Skyworks Solutions 
for $2.75 billion to become a pure-play leader in 
secure, intelligent wireless connectivity. Silicon 
Labs is now solely focused on the Internet of 
Things (IoT), a large, diverse, and rapidly grow-
ing market. 2021 was also a year of innovation:

 ■ Delivering the world’s first sub-GHz wire-

less solutions that combine long-range RF 
and energy efficiency with certified Arm PSA 
Level 3 security to meet the global demand 
for high-performance, battery-powered IoT 
products.

 ■ Expanding on the Series 2 Platform with the 
release of Z-Wave 800 SoCs and modules 
for the Z-Wave smart home and automation 
ecosystem.

 ■ Releasing new Security Services with a first-

of-its-kind Custom Part Manufacturing Service 
(CPMS) for wireless SoCs and modules.

The team delivered great products to market 
and drove record revenue, all while navigat-
ing a uniquely challenging environment. As the 
demand for semiconductors has dramatically 
increased across the entire industry, the global 
foundry capacity has not been able to fulfill 
demand. We expect this supply-limited environ-
ment to persist throughout 2022. Our operations 
team is working around the clock to obtain incre-
mental wafer capacity, and we have been able to 
increase unit shipments each quarter.

Total revenue on a continuing operations basis 
for 2021 was $721 million, a 41% increase over 
2020 revenue, with significant growth in both 
the Industrial & Commercial and the Home & 
Life business units. Smart home, smart city, 
and industrial asset tracking applications grew 
substantially in 2021, along with strong growth 
across most of our end markets. From a technol-
ogy perspective, Bluetooth, WiFi, and our pro-

prietary products all enjoyed high growth rates. 
Our performance in WiFi has been particularly 
impactful as we integrated the Redpine Signals 
business into our portfolio following the 2020 
acquisition. We continued to scale our site in 
Hyderabad at a rapid pace and exited 2021 with 
approximately 350 employees, an increase of 
almost 50% during 2021, at our fastest-growing 
wireless development center.

Over the course of 2021, it became increasingly 
apparent that demand for our wireless connec-
tivity solutions is robust and is a result of the 
acceleration of the digital transformation of our 
economy. We saw this through continued strong 
growth in our opportunity funnel and design 
wins in 2021. Our estimated lifetime revenue for 
design wins at the end of 2021 stood at over $14 
billion, exceeding the level of design wins before 
the divestiture. In addition, the diversity of our 
end markets, customer base, and geographies is 
remarkable, with no single customer represent-
ing more than 5% of our revenue, and our top ten 
customers comprised only 21% of our revenue 
for the year. 

In 2021, we delivered GAAP gross margins of 
59.0 percent and non-GAAP gross margins of 
59.1 percent. GAAP operating margin was -4.6 
percent of revenue, while non-GAAP operat-
ing margin was 9.7 percent of revenue. GAAP 
diluted earnings per share were $47.78, inclusive 
of the gain recognized on the divestiture. Non-
GAAP diluted earnings per share from continuing 
operations increased 8.3 percent to $3.26. Our 
business performance for the second half of 
2021 meaningfully exceeded our expectations 
and validates our view of the potential of the IoT 
market.

We generated $91 million in cash flow from con-
tinuing operations and ended the year with $2 
billion in cash, cash equivalents, and short-term 
investments. Silicon Labs continued its diligent 
stewardship of capital by executing several 
transactions to return $1.15 billion in capital to 
shareholders through share repurchases. 

Our wireless portfolio, partners, and ecosys-
tems remain unmatched in breadth and depth. 
In September, we held our second annual 
WorksWith Developer Conference, which drew 
nearly 8,000 registered attendees—partners, 
developers, and business leaders—for two 
days of virtual keynotes, technical sessions, 
and workshops. Keynotes featured industry 
leaders like Amazon, Google, IKEA, Landis and 
Gyr, and Schneider Electronics. We were once 
again recognized as one of the Most Respected 
Public Semiconductor Companies by the Global 
Semiconductor Alliance. 

We remain committed to advancing our envi-
ronmental, social, and governance efforts – and 
have released our 2021 Corporate Responsibility 
Report with a full overview of our ESG activi-
ties. A few highlights include the creation of the 
Silicon Labs DEI council driving engagement and 
new training opportunities to support our prog-
ress around diversity, equity, and inclusion. We 
also remain steadfast in our dedication to envi-
ronmental sustainability and supporting local 
communities. Specifically, in June, we became 
the first corporate partner to join the Interna-
tional Institute of Information Technology Hyder-
abad’s new Smart City Living Lab, which focuses 
R&D on devices that improve life in densifying 
cities. For 2022, we have announced our inten-
tion to adopt the SASB disclosure framework.

At the close of 2021, we completed a smooth 
leadership transition as Tyson Tuttle retired 
after a decade as CEO and more than 24 years 
with Silicon Labs. Tyson’s impact at Silicon Labs 
continues to be felt and was reflected in our 
recent certification as a Great Place to Work 
again for 2021. As part of our leadership transi-
tion, we introduced a new executive team, with 
the promotions of Jacob Alamat, Senior Vice 
President of Home & Life Business Unit; Benny 
Chang, Senior Vice President of Platform & Chief 
of Staff; Manish Kothari, Senior Vice President 
of Software Development and site leader for our 
operations in India; and Ross Sabolcik, Senior 
Vice President of Industrial & Commercial Busi-
ness Unit. Our leadership team is committed to 

upholding our core values as we build on Silicon 
Labs’ strong foundation.

We started our IoT journey nearly 15 years ago, 
recognizing the power of the Internet of Things 
to transform industries, grow businesses, and 
improve lives. As we pivot into a pure-play 
provider of IoT solutions, we have never been 
more confident in the future of this market and 
its potential to positively impact our world. We 
have established Silicon Labs as a clear leader 
in secure, intelligent wireless connectivity at 
the edge with the broadest portfolio of wireless 
products. Our customers appreciate the bene-
fits of a focused technology leader dedicated to 
enabling their innovative products and solutions. 
Our business is more robust than ever. We’re 
excited to be leading this great team into a new 
era of industry leadership and growth. We have 
the people, the IP, and the vision to capture this 
great market opportunity.

Thank you for your investment in Silicon Labs.

Item 1. Business

Overview

Silicon Laboratories Inc. is a leader in secure, intelligent wireless technology for a more connected

world. Our integrated hardware and software platform, intuitive development tools, industry leading
ecosystem and robust support enable customers in building advanced industrial, commercial, home and
life applications. We make it easy for developers to solve complex wireless challenges throughout the
product lifecycle and get to market quickly with innovative solutions that transform industries, grow
economies and improve lives.

We are pioneers in wireless innovation and have spent the last two decades simplifying the
complexity of radio frequency (“RF”) from silicon to cloud. Our leading IoT platform helps customers
quickly create secure, intelligent connected devices that solve some of the world’s biggest challenges.
Our team and technology assist customers to build connected devices that measurably solve development
challenges, including energy efficiency, economic growth, better health, infrastructure innovation,
sustainable cities and responsible production.

Our semiconductor devices leverage standard complementary metal oxide semiconductor (CMOS),

a low cost, widely available process technology. Use of CMOS technology enables smaller, more
cost-effective and energy-efficient solutions. Our software expertise allows us to develop products for
markets where intelligent data capture, high-performance processing and communication are increasingly
important product differentiators. We also focus design and engineering efforts on technologies that
simplify and accelerate adoption by customers of security features engineered into our silicon chips. Our
expertise in analog-intensive, mixed-signal IC design in CMOS and software development allows us to
develop new and innovative products that are highly integrated and secure, simplifying our customers’
designs and improving their time-to-market.

Industry Background

Intelligence is being added to electronic systems to enable internet connectivity, power efficiency,

monitoring of health, safety and consumption of precious resources and an improved user experience.
This in turn is increasing the demand for bandwidth, requiring more infrastructure to support higher
performance networks. The nearly ubiquitous availability of internet access and the increasing intelligence
of electronic devices and mobility are enabling what is called the Internet of Things, a term that
describes the exponential increase in IP-enabled devices connected to the internet.

These trends require more and more interaction between the analog world we live in and the
digital world of computing, which is driving the need for analog-intensive, mixed-signal circuits in a wide
range of electronic products. Traditional mixed-signal designs relied upon solutions built with numerous,
complex discrete analog and digital components. While these traditional designs provide the required
functionality, they are often inefficient and inadequate for use in markets where size, cost, power
consumption, performance and security are increasingly important product differentiators. To improve
their competitive position, electronics manufacturers must reduce the cost and complexity of their systems
and enable new features or functionality to differentiate themselves from their competitors.

Simultaneously, these manufacturers face accelerating time-to-market demands and must rapidly

adapt to evolving industry standards and new technologies. Because analog-intensive, mixed-signal
design expertise is difficult to find, these manufacturers increasingly are turning to third parties, like us,
to provide advanced mixed-signal solutions. Mixed-signal design requires specific expertise and
relies on creative, experienced engineers to deliver solutions that optimize speed, power and performance,
despite the noisy digital environment, and within the constraints of standard manufacturing processes.
The development of this design expertise typically requires years of practical analog design experience
under the guidance of a senior engineer, and engineers with the required level of skill and expertise
are in short supply.

2

Many IC solution providers lack sufficient analog expertise to develop compelling mixed-signal

products. As a result, manufacturers of electronic devices value providers that can supply them with
mixed-signal solutions offering greater functionality, smaller size and lower power requirements at a
reduced cost and shorter time-to-market.

Products

We provide analog-intensive, mixed-signal solutions for use in a variety of electronic products in a

broad range of applications for the IoT including connected home and security, industrial automation
and control, smart metering, smart lighting, commercial building automation, consumer electronics, asset
tracking and medical instrumentation. We have built a leading wireless development platform and
product portfolio for the IoT based on Zigbee®, sub-GHz proprietary technologies, Bluetooth®, Z-Wave®,
Thread, and Wi-Fi®. We have developed a fully integrated, certified Wi-SUN® solution simplifying Low
Power Wide Area Network (LPWAN) deployment for smart cities.

We have continued to diversify our product portfolio and introduce new products and solutions

through both organic investment and acquisitions. Mergers and acquisitions are an important part of
our growth strategy.

Our products integrate complex mixed-signal functions that are frequently performed by numerous
discrete components in competing products into a single chip, chipset or system-on-chip (SoC). By doing
so, we create products that, when compared to many competing products, offer the following benefits:

• Require less printed circuit board (PCB) space;

• Reduce the use of external components lowering the system cost and simplifying design;

• Offer superior performance improving our customers’ end products;

• Provide increased reliability and manufacturability, improving customer yields; and/or

• Reduce system power requirements enabling smaller form factors and/or longer battery life.

3

Revenues during fiscal 2021, 2020 and 2019 were generated predominately by sales of our mixed-

signal products. The following table summarizes the diverse product areas and applications for the
various products that we have introduced to customers:

Divestiture

On April 22, 2021, we entered into an Asset Purchase Agreement pursuant to which Skyworks

Solutions, Inc. agreed to acquire certain assets, rights, and properties, and assume certain liabilities,

4

comprising our infrastructure and automotive business for $2.75 billion in cash. The transaction closed
on July 26, 2021. See Note 3, Discontinued Operations, to the Consolidated Financial Statements for
additional information.

Customers, Sales and Marketing

We market our products through our direct sales force and through a network of independent
sales representatives and distributors. Direct and distribution customers buy on an individual purchase
order basis, rather than pursuant to long-term agreements.

We consider our customer to be the end customer purchasing either directly from a distributor, a
contract manufacturer or us. During fiscal 2021, our ten largest end customers accounted for 21% of
our revenues. We had no customer that represented more than 10% of our revenues during this period.
An end customer purchasing through a contract manufacturer typically instructs such contract
manufacturer to obtain our products and incorporate such products with other components for sale by
such contract manufacturer to the end customer. Although we sell the products to, and are paid by
distributors and contract manufacturers, we refer to such end customer as our customer. Three of our
distributors who sell to our customers, Arrow Electronics, Edom Technology and Sekorm, each
represented 28%, 18% and 12% of our revenues during fiscal 2021, respectively.

We maintain numerous sales offices in Asia, the Americas and Europe. Revenue is attributed to a

geographic area based on the shipped-to location. The percentage of our revenues derived from outside
of the United States was 86% in fiscal 2021.

Our direct sales force is comprised of many sales professionals who possess varied levels of
responsibility and experience, including directors, country managers, regional sales managers, district
sales managers, strategic account managers, field sales engineers and sales representatives. We also
utilize independent sales representatives and distributors to generate sales of our products. We have
relationships with many independent sales representatives and distributors worldwide whom we have
selected based on their understanding of the mixed-signal marketplace and their ability to provide effective
field sales applications support for our products.

Our marketing efforts are targeted at both identified industry leaders and emerging market
participants. Direct marketing activities are supplemented by a focused marketing communications
effort that seeks to raise awareness of our company and products. Our public relations efforts are
focused on leading trade and business publications. Our external website is used to deliver corporate
and product information. We also pursue targeted advertising in key trade publications and we have a
cooperative marketing program that allows our distributors and representatives to promote our products
to their local markets in conjunction with their own advertising activities. Finally, we maintain a presence
at strategic trade shows and industry events. These activities, in combination with direct sales
activities, help drive demand for our products.

Due to the complex and innovative nature of our products, we employ experienced applications
engineers who work closely with customers and distributors to support the design-win process, and
can significantly accelerate the customer’s time to market. A design win occurs when a customer has
designed our ICs into its product architecture and ordered product from us. A considerable amount of
effort to help a customer incorporate our ICs into its products is typically required prior to any sale. In
many cases, our innovative ICs require significantly different implementations than existing approaches
and, therefore, successful implementations may require extensive communication with potential
customers. The amount of time required to achieve a design win can vary substantially depending on a
customer’s development cycle, which can be relatively short (such as three months) or very long
(such as two years) based on a wide variety of customer factors. Not all design wins ultimately result in
revenue, or may result in less revenue than expected. However, once a completed design architecture
has been implemented and produced in high volumes, our customers are reluctant to significantly alter
their designs due to this extensive design-win process. We believe this process, coupled with our
intellectual property protection, promotes relatively longer product life cycles for our products and high
barriers to entry for competitive products, even if such competing products are offered at lower prices.

5

Our close collaboration with our customers provides us with knowledge of derivative product ideas or
completely new product line offerings that may not otherwise arise in other new product discussions.

Research and Development

Through our research and development efforts, we leverage experienced analog and mixed-signal

engineering talent and expertise to create new ICs that integrate functions typically performed less
efficiently by multiple discrete components. This integration generally results in lower costs, smaller die
sizes, lower power demands and enhanced price/performance characteristics. We attempt to reuse
successful techniques for integration in new applications where similar benefits can be realized. We
believe that we have attracted many of the best engineers in our industry. We believe that reliable and
precise analog and mixed-signal ICs can only be developed by teams of engineers who have significant
analog experience and are familiar with the intricacies of designing these ICs for commercial volume
production. The development of test methodologies is just one example of a critical activity requiring
experience and know-how to enable the rapid release of a new product for commercial success. We have
accumulated a vast set of trade secrets that allow us to pursue innovative approaches to mixed-signal
problems that are difficult for competitors to duplicate. We highly value our engineering talent and strive to
maintain a very high bar when bringing new recruits to the company.

Research and development expenses were $273.2 million, $235.2 million and $205.7 million in

fiscal 2021, 2020 and 2019, respectively.

Technology

Our product development process facilitates the design of highly-innovative, analog-intensive, mixed-

signal ICs. Our engineers’ deep knowledge of existing and emerging standards and performance
requirements helps us to assess the technical feasibility of a particular IC. We target areas where we can
provide compelling product improvements. Once we have solved the primary challenges, our field
application engineers continue to work closely with our customers’ design teams to maintain and develop
an understanding of our customers’ needs, allowing us to formulate derivative products and refined
features.

In providing mixed-signal ICs for our customers, we believe our key competitive advantages are:

• Analog and RF design expertise in CMOS;

• Mixed-signal, firmware and system design expertise;

• Microcontroller and system on a chip design expertise;

• Software expertise, including multiprotocol connectivity and real-time operating systems for the

IoT;

• Module integration and wireless design expertise;

• Silicon-to-cloud security integration expertise; and

• Our broad understanding of systems technology and trends.

To fully capitalize on these advantages, we have assembled a world-class development team with

exceptional analog and mixed-signal design expertise led by accomplished senior engineers.

Analog and RF Design Expertise in CMOS

We believe that our most significant core competency is world-class analog and RF design

capability. Additionally, we strive to design substantially all our ICs in standard CMOS processes. Most
of our product designs now incorporate some type of RF in CMOS technology. While it is often significantly
more difficult to design analog ICs in CMOS, CMOS provides multiple benefits versus existing
alternatives, including significantly reduced cost, reduced technology risk and greater worldwide
foundry capacity. CMOS is the most commonly used process technology for manufacturing digital ICs
and as a result is most likely to be used for the manufacturing of ICs with finer line geometries. These finer

6

line geometries can enable smaller and faster ICs. By designing our ICs in CMOS, we enable our
products to benefit from this trend towards finer line geometries, which allows us to integrate more digital
functionality into our mixed-signal ICs.

Designing analog and mixed-signal ICs is significantly more complicated than designing standalone

digital ICs. While advanced software tools exist to help automate digital IC design, there are far fewer
tools for advanced analog and mixed-signal IC design. In many cases, our analog circuit design efforts
begin at the fundamental transistor level. We believe that we have a demonstrated ability to design
the most difficult analog and RF circuits using standard CMOS technologies.

Mixed-Signal, Firmware and System Design Expertise

We consider the partitioning of a circuit to be a proprietary and creative design technique. Deep

systems knowledge allows us to use our mixed-signal and RF in CMOS design expertise to maximize
the price/performance characteristics of both the analog and digital functions and allow our ICs to work
in an optimized manner to accomplish particular tasks. Generally, we attempt to move analog functions
into the digital domain as quickly as possible, creating system efficiencies without compromising
performance. These patented approaches require our advanced signal processing and systems
expertise. We then leverage our firmware know-how to change the ‘personality’ of our devices, optimizing
features and functions needed by various markets we serve. For example, our wireless SoC devices
for IoT applications integrate both digital and analog domains in a single chip. The SoCs combine ARM
Cortex-M processor cores, a variety of digital and analog peripherals, hardware cryptography
accelerators, and analog-intensive multiprotocol radio transceivers. This system integration at the chip
level leverages our deep expertise in mixed-signal and RF design, and low-power wireless MCU
architectures pioneered for more than a decade.

Microcontroller and System on a Chip Design Expertise

We have the talent and circuit integration methodologies required to combine precision analog, high-

speed digital, flash memory and in-system programmability into a single, monolithic CMOS integrated
circuit. Our microcontroller products are designed to capture an external analog signal, convert it to a
digital signal, compute digital functions on the stream of data and then communicate the results
through a standard digital interface. The ability to develop standard products with the broadest possible
customer application base while being cost efficient with the silicon area of the monolithic CMOS
integrated circuit requires a keen sense of customer value and engineering capabilities. Additionally, to
manage the wide variety of signals on a monolithic piece of silicon including electrical noise, harmonics
and other electronic distortions requires a fundamental knowledge of device physics and accumulated
design expertise.

Software Expertise

Our software expertise allows us to develop products for markets where intelligent data capture, high-

performance processing and communication are increasingly important product differentiators. The
software we have developed to address these markets enables machine-to-machine communications,
providing intelligence to electronic systems. Our products integrate high-performance, low-power wireless
and microcontroller ICs with reliable and scalable software into a flexible and robust networking
platform.

The demand for low-power, small-footprint wireless technology is accelerating as more and more

IP-enabled end points are being connected to the IoT. Our software enables a broad range of
power-sensitive applications for the IoT, including smart energy, home automation, security and other
connected products. We believe that the combination of our software and IC design expertise
differentiates us from many of our competitors.

As the IoT continues to mature, a new class of embedded applications is emerging, presenting

feature-rich and task-intensive use cases. This growing complexity is driving the need for real-time
operating systems to help simplify software development for IoT applications by coordinating and
prioritizing multiprotocol connectivity, SoC peripherals and other system-level activities. In addition to

7

being able to manage numerous application tasks, an RTOS enhances scalability, and makes complex
applications predictable and reliable. To address these application needs, in 2016 we acquired
Micrium, an embedded RTOS provider. Micrium has established itself as a reliable, high performance
and trusted RTOS software platform, with an installed base that has grown to millions of devices.

Module Integration and Wireless Design Expertise

The market for wireless modules has grown as customers search for solutions that provide turnkey

wireless connectivity for their products. The development of modules is difficult due to stringent
requirements, including high levels of integration, programmability, performance, reliability, security and
power efficiency. In addition, designs must meet numerous wireless standards deployed in various
environments and serving diverse requirements.

Our combined expertise in IC design and software development allows us to engineer modules

that provide robust, high-performance connections in challenging wireless environments. We have
developed wireless modules based on numerous wireless standards, including Z-Wave, Bluetooth,
Zigbee, Thread, Wi-Fi and sub-GHz. We believe our demonstrated proficiency in the design of modules
provides our customers with significant advantages such as fast time to market, reduced development
cost, global wireless certifications and software reuse.

Silicon-to-Cloud Security Integration Expertise

Security is of paramount importance to our customers. More than ever before, device manufacturers

and OEMs developing IoT products have specific needs to ensure their solutions are secure. Security
is a complex endeavor involving the convergence of multiple integrated hardware and software
technologies. IoT products are designed to ensure the devices operate in a trusted and reliable manner,
enforce policies as well as protect the confidentiality, authenticity and integrity of data and private
information being processed and transmitted. The building blocks are built in hardware based on
dedicated IC security components integrated into SoC designs. These specialized security components
are designed to enhance cryptographic capabilities and exploit unique physical characteristics of
CMOS to establish foundations of trust and enable device identity and assurance.

In addition to developing specific security hardware and software capabilities, we also focus design
and engineering efforts on technologies that simplify and accelerate adoption by customers of security
features engineered into our silicon chips. This is primarily achieved through software tools such as
Simplicity Studio and its integration with cloud-based services that simplify implementation, reduce
complexity and enable management of security for fleets of devices. Those capabilities are designed to
help customers develop products and solutions with chip-to-cloud security integration, enable faster
time to market and reduce security defects, risks and losses due to security attacks and incidents. We
are creating innovative security solutions that enable customers to develop best-in-class, simple and
economical solutions. We will continue investing in security-specific research and development that
addresses a dynamic threat landscape, emerging regulatory requirements, and evolving customer
security and privacy needs.

Understanding of Systems Technology and Trends

Our focused expertise in mixed-signal ICs is the result of the breadth of engineering talent we

have assembled with experience working in analog-intensive CMOS design for a wide variety of
applications. This expertise, which we consider a competitive advantage, is the foundation of our in-
depth understanding of the technology and trends that impact electronic systems and markets. Our
expertise includes:

• Frequency synthesis, which is core technology for wireless and clocking applications;

• Integration, which enables the elimination of discrete components in a system; and

• Signal processing and precision analog, which forms the heart of consumer, industrial, medical

and automotive electronics applications.

8

Our understanding of the role of analog/digital interfaces within electronic systems, standards
evolution, and end market drivers enables us to identify product development opportunities and capitalize
on market trends.

Manufacturing

As a fabless semiconductor company, we conduct IC design and development in our facilities and
electronically transfer our proprietary IC designs to third-party semiconductor fabricators who process
silicon wafers to produce the ICs that we design. Our IC designs typically use industry-standard CMOS
manufacturing process technology to achieve a level of performance normally associated with more
expensive special-purpose IC fabrication technology. We believe the use of CMOS technology facilitates
the rapid production of our ICs within a lower cost framework. Our IC production employs submicron
process geometries which are readily available from leading foundry suppliers worldwide, thus increasing
the likelihood that manufacturing capacity will be available throughout our products’ life cycles. We
currently partner primarily with Taiwan Semiconductor Manufacturing Co. (TSMC) and Semiconductor
Manufacturing International Corporation (SMIC) to manufacture the majority of our semiconductor wafers.
We believe that our fabless manufacturing model significantly reduces our capital requirements and
allows us to focus our resources on design, development and marketing of our ICs.

Once the silicon wafers have been produced, they are shipped directly to our third-party assembly

subcontractors. The assembled ICs are then moved to the final testing stage. This operation can be
performed by the same contractor that assembled the IC, other third-party test subcontractors or within
our internal facilities prior to shipping to our customers. During fiscal 2021, most of our units shipped
were tested by offshore third-party test subcontractors. We expect that our utilization of offshore
third-party test subcontractors will remain substantial during fiscal 2022.

The impacts of the COVID-19 pandemic on our suppliers are uncertain, evolving and dependent

on numerous unpredictable factors outside of our control. If our suppliers experience closures or
reductions in their capacity utilization levels in the future, we may have difficulty sourcing materials
necessary to fulfill production requirements. Disruptions to our business and supply chain (and the
business and supply chains of our customers) could cause significant delays in shipments of our
products until we are able to shift our manufacturing, assembling or testing from the affected subcontractor
to another third-party vendor. Capacity is currently limited at certain of our third-party foundry, assembly
and test subcontractors due to a spike in semiconductor demand.

Backlog

We include in backlog accepted product purchase orders from customers and worldwide distributor
stocking orders. Product orders in our backlog are subject to changes in delivery schedules or cancellation
at the option of the purchaser typically without penalty. Our backlog may fluctuate significantly
depending upon customer order patterns which may, in turn, vary considerably based on rapidly
changing business circumstances. Accordingly, we do not believe that our backlog at any time is
necessarily representative of actual sales for any succeeding period.

Competition

The markets for semiconductors generally, and for analog and mixed-signal ICs in particular, are
intensely competitive. We anticipate that the market for our products will continually evolve and will be
subject to rapid technological change. We believe the principal competitive factors in our industry are:

•

•

•

•

•

•

Product size;

Level of integration;

Product capabilities;

Reliability;

Price;

Performance;

•

•

•

•

•

•

Power requirement;

Customer support;

Reputation;

Ability to rapidly introduce new products to market;

Intellectual property; and

Software.

9

We believe that we are competitive with respect to these factors, particularly because our ICs

typically are smaller in size, are highly integrated, achieve high performance specifications at lower
price points than competitive products and are manufactured in standard CMOS which generally enables
us to supply them on a relatively rapid basis to customers to meet their product introduction schedules.
However, disadvantages we face include our relatively short operating history in certain of our markets
and the need for customers to redesign their products and modify their software to implement our ICs in
their products.

Due to our diversified product portfolio and the numerous markets and applications we serve, we

target a relatively large number of competitors. We compete with Broadcom, Espressif, Infineon,
MediaTek, Microchip, Nordic Semiconductor, NXP, Qualcomm, Renesas, STMicroelectronics, Synaptics,
Telink, Texas Instruments and others. We expect to face competition in the future from our current
competitors, other manufacturers and designers of semiconductors and start-up semiconductor design
companies. Our competitors may also offer bundled solutions offering a more complete product,
which may negatively impact our competitive position despite the technical merits or advantages of our
products. In addition, our customers could develop products or technologies internally that would
replace their need for our products and would become a source of competition. We could also face
competition from module makers or other systems suppliers that may include mixed-signal components
in their products that could eliminate the need for our ICs.

Many of our competitors and potential competitors have longer operating histories, greater name

recognition, access to larger customer bases, complementary product offerings, and significantly greater
financial, sales and marketing, manufacturing, distribution, technical and other resources than us.
Current and potential competitors have established or may establish financial and strategic relationships
between themselves or with our existing or potential customers, resellers or other third parties.
Accordingly, it is possible that new competitors or alliances among competitors could emerge and
rapidly acquire significant market share.

Intellectual Property

Our future success depends in part upon our proprietary technology. We seek to protect our
technology through a combination of patents, copyrights, trade secrets, trademarks and confidentiality
procedures. As of January 1, 2022, we had approximately 1,377 issued or pending United States and
foreign patents. Patents generally have a term of twenty years from the date they are filed. As our
patent portfolio has been built over time, the remaining terms of the individual patents in our patent
portfolio vary. There can be no assurance that patents will ever be issued with respect to our patent
applications. Furthermore, it is possible that any patents held by us may be invalidated, circumvented,
challenged or licensed to others. In addition, there can be no assurance that such patents will provide us
with competitive advantages or adequately safeguard our proprietary rights. While we continue to file
new patent applications with respect to our recent developments, existing patents are granted for
prescribed time periods and will expire at various times in the future.

We claim copyright protection for proprietary documentation for our products. We have filed for
registration, or are in the process of filing for registration, the visual images of certain ICs with the U.S.
Copyright Office. We have registered the “Silicon Labs” logo and a variety of other product and
product family names as trademarks in the United States and selected foreign jurisdictions. All other
trademarks, service marks or trade names appearing in this report are the property of their respective
owners. We also attempt to protect our trade secrets and other proprietary information through
agreements with our customers, suppliers, employees and consultants, and through other customary
security measures. We intend to protect our rights vigorously, but there can be no assurance that our
efforts will be successful. In addition, the laws of other countries in which our products are sold may not
protect our products and intellectual property rights to the same extent as the laws of the United
States.

While our ability to effectively compete depends in large part on our ability to protect our intellectual
property, we believe that our technical expertise and ability to introduce new products in a timely manner
will be an important factor in maintaining our competitive position.

10

Many participants in the semiconductor and electronics industries have a significant number of
patents and have frequently demonstrated a readiness to commence litigation based on allegations of
patent and other intellectual property infringement. From time to time, third parties may assert
infringement claims against us. We may not prevail in any such litigation or may not be able to license
any valid and infringed patents from third parties on commercially reasonable terms, if at all. Litigation,
regardless of the outcome, is likely to result in substantial cost and diversion of our resources, including
our management’s time. Any such litigation could materially adversely affect us.

Our licenses include industry standard licenses with our vendors, such as wafer fabrication tool

libraries, third-party core libraries, computer-aided design applications and business software
applications.

Human Capital

Our success depends on our ability to continue to attract, retain and motivate qualified employees,

particularly highly skilled analog and mixed-signal engineers and senior management personnel. We
strive to meet this objective by offering competitive compensation and benefits in a diverse, inclusive and
safe workplace, with opportunities for our employees to grow and develop in their careers.

As of January 1, 2022, we employed 1,667 people, of whom more than 60% are in engineering

roles. Women represent approximately 20% of our workforce and men represent approximately 80%.
We are a multi-national and multi-ethnic workforce, with sites and employees in more than a dozen
countries. We are committed to fostering a diverse and inclusive workplace that attracts and retains
exceptional talent. We actively promote diversity in our recruitment, development and promotion practices.
These principles are also reflected in our employee training, in particular with respect to our policies
against harassment, discrimination and the elimination of bias in the workplace.

We hold our employees to high performance standards and our compensation plans are designed
to deliver competitive base pay and attractive incentive opportunities. Our benefits programs are tailored
to the various countries in which we operate. We benchmark for market practices, and regularly
review our compensation and benefit programs against the market to ensure they remain competitive.

We support a high-performance culture through learning and development solutions aligned with

our strategic priorities. Our approach is business-centric, accessible and inclusive. Employees
continuously collaborate and share their expertise through an internal training program consisting of
classes and workshops that help strengthen technical and professional skills and advance careers. We
also host university professors and external speakers to broaden knowledge, trigger creativity and
inspire innovation. Our e-learning libraries and on-demand training videos allow employees to absorb
information at their own pace and share their recommendations with co-workers. Employees are invited
to attend our annual two-day technical symposium featuring peer-reviewed presentations showcasing
our internal technical achievements and talks from outside experts to educate and inspire our workforce.
Our talent development programs provide employees with the resources they need to help achieve
their career goals, build management skills and lead their organizations. We regularly review succession
plans and focus on promoting internal talent to help grow our employees’ careers.

We believe that our future success will be dependent on retaining the services of our key personnel,
developing their successors and properly managing the transition of key roles when they occur. Our key
technical personnel represent a significant asset and serve as the primary source for our technological
and product innovations. We use employee surveys to better understand and improve the employee
experience and identify opportunities to continually strengthen our work philosophy. We use employee
feedback to drive and improve processes and ensure a deep understanding of our culture and vision
among our employees. We believe the development of our company culture, along with competitive
compensation, career growth and development opportunities have helped increase employee tenure
and reduce voluntary turnover. During fiscal 2021, our voluntary employee turnover rate was
approximately 10%.

The health and safety of our employees is of utmost important to us. We offer comprehensive

benefits to protect the health of our employees and their families as well as their way of life. We

11

provide our employees and their families with access to a variety of innovative, flexible and convenient
health and wellness programs that support their physical and mental health by providing tools and
resources to help them improve or maintain their health status. In response to the COVID-19 pandemic,
we implemented a response plan that we believe was in the best interest of our employees and the
communities in which we operate. This included largely transitioning our global workforce to a remote
work model, while implementing additional safety measures for essential employees continuing critical
on-site work.

Corporate Social Responsibility

As a global corporate citizen, we are committed to environmental sustainability, operational
excellence, and providing support for people and communities around the world. We live by our
promise to “do the right thing” for our employees, customers, shareholders, communities and planet.
We strive to minimize resource use and reduce the environmental impact of our production processes
by designing smaller and more energy-efficient products, conserving energy and precious resources,
and investing in sustainable technologies and energy conservation practices. Innovative solutions
don’t stop at our products—we are focused on addressing complex community challenges through
collaborative, actionable and results-driven programs. Our philanthropy program provides financial,
volunteer and in-kind support to organizations that are solving critical community needs, improving the
quality of life, including those promoting diversity, inclusion and social justice, and expanding STEM
opportunities for underrepresented groups. Actions we have taken in pursuit of these commitments
include:

Environmental Programs

• Adopted and require our suppliers to support the Responsible Business Alliance® (RBA®) Code

of Conduct;

• Prioritized qualified suppliers who are socially and environmentally progressive;

• Delivered products that met environmental regulations and requirements; and

• Demanded excellence in our quality and environmental management systems, each certified to

ISO 9001 and ISO 14001 standards.

Social Programs

• Donated a portion of our annual profits to charitable organizations;

• Allocated funds to our global sites for grants supporting critical causes locally;

• Provided corporate matching gifts to expand the impact of individual employee donations;

• Offered 24 hours of paid time off per year for employees to volunteer in their communities;

• Sponsored community service projects and supported relief efforts when disasters occur;

• Partnered with organizations committed to building diverse, equitable, and inclusive environments;

• Provided financial grants to nonprofits offering STEM education programs for underrepresented

and underserved groups; and

• Supported research to improve safety, sustainability, and overall quality of life in densifying

cities.

Governmental Regulations

We are subject to international, federal, state and local regulations that are customary to businesses

in the semiconductor industry. Such regulations include:

• The Restriction of Hazardous Substances Directive (“RoHS”), which restricts the use of certain

hazardous substances in electrical and electronic equipment;

• General Data Protection Regulation (“GDPR”), which provides guidelines for the collection and

processing of personal information from individuals who live in the European Union;

12

• The U.S. Foreign Corrupt Practices Act (“FCPA”), which prohibits companies and their individual

officers from influencing foreign officials with any personal payments or rewards; and

• Conflict minerals reporting, which imposes disclosure requirements regarding the use of

“conflict” minerals mined from the Democratic Republic of Congo and adjoining countries in
products.

Our compliance with these laws and regulations has not had a material impact on our financial

position or results of operations.

Item 1A. Risk Factors

Global Business Risks

The COVID-19 pandemic could adversely affect our business, results of operations, and
financial condition

The COVID-19 pandemic has negatively impacted the global economy, disrupted global supply
chains and created significant volatility and disruption of financial markets. The extent of the impact of
the COVID-19 pandemic on our operational and financial performance will depend on future
developments, including the duration, severity and spread of the pandemic, related restrictions on
travel and transportation and other actions that may be taken by governmental authorities, the impact
to the business of our suppliers or customers and other items identified in the risk factors below, all of
which are uncertain and cannot be predicted.

The impacts of the COVID-19 pandemic, or a similar public health crisis, on our business,
customers, suppliers, employees, markets and financial results and condition are uncertain, evolving
and dependent on numerous unpredictable factors outside of our control, including:

• The duration and impact of a global economic recession or depression that could reduce

demand and/or pricing for our products;

• Disruptions to our business and supply chain (and the business and supply chains of our

customers) in connection with the sourcing of materials, equipment and engineering support,
and services from geographic areas impacted by the public health crisis, including disruptions
caused by illnesses, quarantines and restrictions on people’s ability to work, office and factory
closures, disruptions to ports and other shipping infrastructure, border closures, and other travel or
health-related restrictions;

• Delays or limitations on the ability of our customers to make timely payments;

• Governmental actions to limit exposure to and spreading of such infectious diseases, such as

travel restrictions, quarantines and business shutdowns or slowdowns, facility closures or other
restrictions;

• Deterioration of worldwide credit and financial markets that could limit our ability to obtain

external financing to fund our operations and capital expenditures or to refinance our existing
indebtedness;

• Potential asset impairments, including goodwill, intangible assets, investments and other assets;

• Complexities related to our employees temporarily working from home as well as increased cyber-

related risks due to our employees working from home;

• Potential failure of our computer systems or communication systems; and

• Investment-related risks, including difficulties in liquidating investments due to current market

conditions and adverse investment performance.

There can be no assurance that any decrease in sales resulting from the COVID-19 pandemic or a

similar public health crisis will be offset by increased sales in subsequent periods. Even after the
COVID-19 pandemic or a similar public health crisis has subsided, we may continue to experience
materially adverse impacts to our business as a result of its global economic impact, including any
recession, economic downturn or increased unemployment that has occurred or may occur in the future.
An extended period of global supply chain and economic disruption could materially affect our business,
results of operations, access to sources of liquidity and financial condition.

We are subject to the cyclical nature of the semiconductor industry, which has been subject to
significant fluctuations

The semiconductor industry is highly cyclical and is characterized by constant and rapid

technological change, rapid product obsolescence and price erosion, evolving standards, short product

14

life cycles and wide fluctuations in product supply and demand. The industry has experienced significant
fluctuations, often connected with, or in anticipation of, maturing product cycles and new product
introductions of both semiconductor companies’ and their customers’ products and fluctuations in
general economic conditions. Deteriorating general worldwide economic conditions, including reduced
economic activity, concerns about credit and inflation, increased energy costs, decreased consumer
confidence, reduced corporate profits, decreased spending and similar adverse business conditions,
would make it very difficult for our customers, our vendors, and us to accurately forecast and plan future
business activities and could cause U.S. and foreign businesses to slow spending on our products.
We cannot predict the timing, strength, or duration of any economic slowdown or economic recovery. If
the economy or markets in which we operate deteriorate, our business, financial condition, and
results of operations would likely be materially and adversely affected.

Downturns have been characterized by diminished product demand, production overcapacity, high
inventory levels and accelerated erosion of average selling prices. Upturns have been characterized by
increased product demand and production capacity constraints created by increased competition for
access to third-party foundry, assembly and test capacity. We are dependent on the availability of such
capacity to manufacture, assemble and test our products. Foundry, assembly and test capacity is
currently limited due to a spike in semiconductor demand. None of our third-party foundry, assembly or
test subcontractors have provided assurances that adequate capacity will be available to us.

In addition, the COVID-19 pandemic has caused further global economic uncertainty. The impact

from the rapidly changing market and economic conditions due to the COVID-19 outbreak is uncertain,
disrupting the business of our customers and suppliers, and could impact our business and operating
results in the future.

We are a global company, which subjects us to additional business risks including logistical
and financial complexity, political instability and currency fluctuations

We have established international subsidiaries and have opened offices in international markets to

support our activities in Asia, the Americas and Europe. This has included the establishment of a
headquarters in Singapore for non-U.S. operations. During fiscal 2021, the percentage of our revenues
derived from outside of the United States was 86% (and the revenue associated with end customers
in China was 24%, and revenue attributed to China based on shipped-to location was 43%). We may not
be able to maintain or increase global market demand for our products. Our international operations
are subject to a number of risks, including:

• Complexity and costs of managing international operations and related tax obligations, including

our headquarters for non-U.S. operations in Singapore;

• Protectionist laws and business practices, including trade restrictions, tariffs, export controls,

quotas and other trade barriers, including China-U.S. trade policies;

• Trade tensions, geopolitical uncertainty, or governmental actions, including those arising from

the trade dispute between the U.S. and China, may lead customers to favor products from non-US
companies which could put us at a competitive disadvantage and result in decreased customer
demand for our products and our customers’ products;

• Restrictions or tariffs imposed on certain countries and sanctions or export controls imposed on

customers or suppliers may affect our ability to sell and source our products;

• Difficulties related to the protection of our intellectual property rights in some countries;

• Public health crises, such as the COVID-19 pandemic, may affect our international operations,
suppliers and customers and we may experience delays in product development, a decreased
ability to support our customers and reduced design win activity if the travel restrictions or
business shutdowns or slowdowns continue for an extended period of time in any of the countries
in which we, our suppliers and our customers operate and do business;

• Multiple, conflicting and changing tax and other laws and regulations that may impact both our

international and domestic tax and other liabilities and result in increased complexity and costs,

15

including the impact of the Tax Cuts and Jobs Act, which we expect to increase our effective tax
rate, in part due to the impact of the requirement to capitalize and amortize foreign research
and development expenses beginning in 2022;

• Longer sales cycles;

• Greater difficulty in accounts receivable collection and longer collection periods;

• High levels of distributor inventory subject to price protection and rights of return to us;

• Political and economic instability;

• Greater difficulty in hiring and retaining qualified personnel; and

• The need to have business and operations systems that can meet the needs of our international

business and operating structure.

To date, substantially all of our sales to international customers and purchases of components

from international suppliers have been denominated in U.S. dollars. As a result, an increase in the
value of the U.S. dollar relative to foreign currencies could make our products more expensive for our
international customers to purchase, thus rendering our products less competitive. Similarly, a decrease
in the value of the U.S. dollar could reduce our buying power with respect to international suppliers.

Our research and development efforts are focused on a limited number of new technologies and
products, and any delay in the development, or abandonment, of these technologies or products
by industry participants, or their failure to achieve market acceptance, could compromise our
competitive position

Our products serve as components and solutions in electronic devices in various markets. As a

result, we have devoted and expect to continue to devote a large amount of resources to develop
products based on new and emerging technologies and standards that will be commercially introduced
in the future. Research and development expense during fiscal 2021 was $273.2 million, or 37.9% of
revenues. A number of companies are actively involved in the development of these new technologies
and standards. Should any of these companies delay or abandon their efforts to develop commercially
available products based on new technologies and standards, our research and development efforts
with respect to these technologies and standards likely would have no appreciable value. In addition, if
we do not correctly anticipate new technologies and standards, or if the products that we develop
based on these new technologies and standards fail to achieve market acceptance, our competitors
may be better able to address market demand than we would. Furthermore, if markets for these new
technologies and standards develop later than we anticipate, or do not develop at all, demand for our
products that are currently in development would suffer, resulting in lower sales of these products than we
currently anticipate.

Competition within the numerous markets we target may reduce sales of our products and
reduce our market share

The markets for semiconductors in general, and for mixed-signal products in particular, are
intensely competitive. We expect that the market for our products will continually evolve and will be
subject to rapid technological change. In addition, as we target and supply products to numerous markets
and applications, we face competition from a relatively large number of competitors. We compete with
Broadcom, Espressif, Infineon, MediaTek, Microchip, Nordic Semiconductor, NXP, Qualcomm, Renesas,
STMicroelectronics, Synaptics, Telink, Texas Instruments and others. We expect to face competition in
the future from our current competitors, other manufacturers and designers of semiconductors, and
start-up semiconductor design companies. As the markets for communications products grow, we
also may face competition from traditional communications device companies. These companies may
enter the mixed-signal semiconductor market by introducing their own products or by entering into
strategic relationships with or acquiring other existing providers of semiconductor products. In addition,
large companies may restructure their operations to create separate companies or may acquire new
businesses that are focused on providing the types of products we produce or acquire our customers.

16

We rely on third parties to manufacture, assemble and test our products and the failure to
successfully manage our relationships with our manufacturers and subcontractors would
negatively impact our ability to sell our products

We do not have our own wafer fab manufacturing facilities. Therefore, we rely on third-party
vendors to manufacture the products we design. We also currently rely on third-party assembly
subcontractors in Asia to assemble and package the silicon chips provided by the wafers for use in
final products. Additionally, we rely on these offshore subcontractors for a substantial portion of the
testing requirements of our products prior to shipping. We expect utilization of third-party subcontractors
to continue in the future.

The cyclical nature of the semiconductor industry drives wide fluctuations in available capacity at

third-party vendors. On occasion, we have been unable to adequately respond to unexpected increases
in customer demand due to capacity constraints and, therefore, were unable to benefit from this
incremental demand. We may be unable to obtain adequate foundry, assembly or test capacity from
our third-party subcontractors to meet our customers’ delivery requirements even if we adequately
forecast customer demand. For example, foundry, assembly and test capacity is currently limited due to
a spike in semiconductor demand. As a result, we have recently experienced longer lead times at
certain third-party foundry subcontractors. This is resulting in competing demand for capacity at our
suppliers. Such conditions may adversely affect our revenue and increase our costs.

There are significant risks associated with relying on these third-party foundries and subcontractors,

including:

• Failure by us, our customers or their end customers to qualify a selected supplier;

• Potential insolvency of the third-party subcontractors;

• Reduced control over delivery schedules and quality;

• Limited warranties on wafers or products supplied to us;

• Potential increases in prices or payments in advance for capacity;

• Increased need for international-based supply, logistics and financial management;

• Disruption to our supply chain resulting from cyber-attacks on our suppliers’ information

technology systems;

• Their inability to supply or support new or changing packaging technologies; and

• Low test yields.

We typically do not have long-term supply contracts with our third-party vendors which obligate the
vendor to perform services and supply products to us for a specific period, in specific quantities, and at
specific prices. Our third-party foundry, assembly and test subcontractors typically do not guarantee
that adequate capacity will be available to us within the time required to meet demand for our products.
In the event that these vendors fail to meet our demand for whatever reason, we expect that it would
take up to 12 months to transition performance of these services to new providers. Such a transition may
also require qualification of the new providers by our customers or their end customers.

If our suppliers experience closures or reductions in their capacity utilization levels in the future,
we may have difficulty sourcing materials necessary to fulfill production requirements. Public health
crises, such as the COVID-19 pandemic, may affect our suppliers’ production capabilities as a result of
quarantines, closures of production facilities, lack of supplies or delays caused by restrictions on
travel.

Most of the silicon wafers for the products that we have sold were manufactured either by Taiwan
Semiconductor Manufacturing Co. (TSMC) or Semiconductor Manufacturing International Corporation
(SMIC). Our customers typically complete their own qualification process. If we fail to properly balance
customer demand across the existing semiconductor fabrication facilities that we utilize or are required
by our foundry partners to increase, or otherwise change the number of fab lines that we utilize for our

17

production, we might not be able to fulfill demand for our products and may need to divert our engineering
resources away from new product development initiatives to support the fab line transition, which
would adversely affect our operating results.

We may not be able to maintain our historical growth and may experience significant period-to-
period fluctuations in our revenues and operating results, which may result in volatility in our
stock price

Although we have generally experienced revenue growth in our history, we may not be able to

sustain this growth. We may also experience significant period-to-period fluctuations in our revenues
and operating results in the future due to a number of factors, and any such variations may cause our
stock price to fluctuate. In some future period our revenues or operating results may be below the
expectations of public market analysts or investors. If this occurs, our stock price may drop, perhaps
significantly.

A number of factors, in addition to those cited in other risk factors applicable to our business, may

contribute to fluctuations in our revenues and operating results, including:

• The timing and volume of orders received from our customers;

• The timeliness of our new product introductions and the rate at which our new products may

cannibalize our older products;

• The rate of acceptance of our products by our customers, including the acceptance of new

products we may develop for integration in the products manufactured by such customers, which
we refer to as “design wins”;

• The time lag and realization rate between “design wins” and production orders;

• Supplier capacity constraints;

• The demand for, and life cycles of, the products incorporating our mixed-signal solutions;

• The rate of adoption of mixed-signal products in the markets we target;

• Deferrals or reductions of customer orders in anticipation of new products or product

enhancements from us or our competitors or other providers of mixed-signal ICs;

• Changes in product mix;

• The average selling prices for our products could drop suddenly due to competitive offerings or

competitive predatory pricing;

• The average selling prices for our products generally decline over time;

• Changes in market standards;

• Impairment charges related to inventory, equipment or other long-lived assets;

• The software used in our products, including software provided by third parties, may not meet

the needs of our customers;

• Our customers may not be able to obtain other components such as capacitors (which are

currently in short supply) that they need to incorporate in conjunction with our products, leading
to potential downturn in the demand for our products;

• Significant legal costs to defend our intellectual property rights or respond to claims against us;

and

• The rate at which new markets emerge for products we are currently developing or for which our

design expertise can be utilized to develop products for these new markets.

The markets for consumer electronics, for example, are characterized by rapid fluctuations in
demand and seasonality that result in corresponding fluctuations in the demand for our products that
are incorporated in such devices. Additionally, the rate of technology acceptance by our customers

18

results in fluctuating demand for our products as customers are reluctant to incorporate a new IC into
their products until the new IC has achieved market acceptance. Once a new IC achieves market
acceptance, demand for the new IC can quickly accelerate to a point and then level off such that rapid
historical growth in sales of a product should not be viewed as indicative of continued future growth. In
addition, demand can quickly decline for a product when a new IC product is introduced and receives
market acceptance. Due to the various factors mentioned above, the results of any prior quarterly or
annual periods should not be relied upon as an indication of our future operating performance.

We may be the victim of business disruptions and security breaches, including cyber-attacks,
which could lead to liability or could damage our reputation and financial results

Information technology system and/or network disruptions, regardless of the cause, but including

acts of sabotage, error, or other actions, could harm the company’s operations. Failure to effectively
prevent, detect, and recover from security breaches, including cyber-attacks, could result in the misuse
of company assets, disruption to the company, diversion of management resources, regulatory
inquiries, legal claims or proceedings, reputational damage, loss of sales and other costs to the company.
We routinely face attacks that attempt to breach our security protocols, gain access to or disrupt our
computerized systems or steal proprietary company, customer, partner or employee information. These
attacks are sometimes successful. These attacks may be due to security breaches, employee error,
theft, malfeasance, phishing schemes, ransomware, faulty password or data security management, or
other irregularities. The theft, loss, destruction, unavailability or misuse of personal or business data
collected, used, stored or transferred by us to run our business could result in increased security
costs or costs related to defending legal claims. Industrial espionage, theft or loss of our intellectual
property data could lead to counterfeit products or harm the competitive position of our products and
services. Costs to implement, test and maintain measures to promote compliance with applicable privacy
and data security laws as well as to protect the overall security of our system have been and are
expected to continue to be significant. Attempted or successful attacks against our products and services
could damage our reputation with customers or users and reduce demand for our products and
services.

Additionally, there is an increased risk that we may experience cybersecurity-related events such

as COVID-19 themed phishing attacks and other security challenges as a result of most of our
employees and our service providers working remotely from non-corporate managed networks during
the ongoing COVID-19 pandemic and potentially continuing working remotely even after the COVID-19
pandemic has subsided.

We depend on our key personnel to manage our business effectively in a rapidly changing
market, and if we are unable to retain our current personnel and hire additional personnel, our
ability to develop and successfully market our products could be harmed

We believe our future success will depend in large part upon our ability to attract and retain highly
skilled managerial, engineering, sales and marketing personnel. We believe that our future success will
be dependent on retaining the services of our key personnel, developing their successors and certain
internal processes to reduce our reliance on specific individuals, and on properly managing the transition
of key roles when they occur. There is currently a shortage of qualified personnel with significant
experience in the design, development, manufacturing, marketing and sales of analog and mixed-
signal products. In particular, there is a shortage of engineers who are familiar with the intricacies of
the design and manufacturability of analog elements, and competition for such personnel is intense. Our
key technical personnel represent a significant asset and serve as the primary source for our
technological and product innovations. We may not be successful in attracting and retaining sufficient
numbers of technical personnel to support our anticipated growth. The loss of any of our key employees
or the inability to attract or retain qualified personnel both in the United States and internationally,
including engineers, sales, applications and marketing personnel, could delay the development and
introduction of, and negatively impact our ability to sell, our products.

If we are unable to develop or acquire new and enhanced products that achieve market
acceptance in a timely manner, our operating results and competitive position could be harmed

Our future success will depend on our ability to develop or acquire new products and product
enhancements that achieve market acceptance in a timely and cost-effective manner. The development

19

of mixed-signal ICs is highly complex, and we have at times experienced delays in completing the
development and introduction of new products and product enhancements. Successful product
development and market acceptance of our products depend on a number of factors, including:

• Requirements of customers;

• Accurate prediction of market and technical requirements;

• Timely completion and introduction of new designs;

• Timely qualification and certification of our products for use in our customers’ products;

• Commercial acceptance and volume production of the products into which our ICs will be

incorporated;

• Availability of foundry, assembly and test capacity;

• Achievement of high manufacturing yields;

• Quality, price, performance, power use and size of our products;

• Availability, quality, price and performance of competing products and technologies;

• Our customer service, application support capabilities and responsiveness;

• Successful development of our relationships with existing and potential customers;

• Technology, industry standards or end-user preferences; and

• Cooperation of third-party software providers and our semiconductor vendors to support our

chips within a system.

We cannot provide any assurance that products which we recently have developed or may develop

in the future will achieve market acceptance. We have introduced to market or are in development of
many products. If our products fail to achieve market acceptance, or if we fail to develop new products
on a timely basis that achieve market acceptance, our growth prospects, operating results and competitive
position could be adversely affected. The growth of the IoT market is dependent on the adoption of
industry standards to permit devices to connect and communicate with each other. If the industry cannot
agree on a common set of standards, then the growth of the IoT market may be slower than expected.

Any acquisitions we make could disrupt our business and harm our financial condition

As part of our growth and product diversification strategy, we continue to evaluate opportunities to

acquire other businesses, intellectual property or technologies that would complement our current
offerings, expand the breadth of our markets or enhance our technical capabilities. The acquisitions that
we have made and may make in the future entail a number of risks that could materially and adversely
affect our business and operating results, including:

• Problems integrating the acquired operations, technologies or products with our existing

business and products;

• Diversion of management’s time and attention from our core business;

• Need for financial resources above our planned investment levels;

• Difficulties in retaining business relationships with suppliers and customers of the acquired

company;

• Risks associated with entering markets in which we lack prior experience;

• Risks associated with the transfer of licenses of intellectual property;

• Increased operating costs due to acquired overhead;

• Tax issues associated with acquisitions;

• Acquisition-related disputes, including disputes over earn-outs and escrows;

20

• Potential loss of key employees of the acquired company; and

• Potential impairment of related goodwill and intangible assets.

In particular, the extent of the impact of the COVID-19 pandemic on our ability to complete and
integrate any future acquisition into our business is unpredictable and will depend on future developments,
including the duration, severity and spread of the pandemic, related restrictions on travel and
transportation, and other actions that may be taken by governmental authorities. Future acquisitions
also could cause us to incur debt or contingent liabilities or cause us to issue equity securities that could
negatively impact the ownership percentages of existing shareholders.

The average selling prices of our products could decrease rapidly which may negatively impact
our revenues and gross profit

We may experience substantial period-to-period fluctuations in future operating results due to the

erosion of our average selling prices. We have reduced the average unit price of our products in
anticipation of or in response to competitive pricing pressures, new product introductions by us or our
competitors and other factors. If we are unable to offset any such reductions in our average selling prices
by increasing our sales volumes, increasing our sales content per application or reducing production
costs, our gross profit and revenues will suffer. To maintain our gross profit, we will need to develop and
introduce new products and product enhancements on a timely basis and continually reduce our
costs. Our failure to do so could cause our revenues and gross profit to decline.

Failure to manage our distribution channel relationships could impede our future growth

The future growth of our business will depend in large part on our ability to manage our relationships

with current and future distributors and sales representatives, develop additional channels for the
distribution and sale of our products and manage these relationships. During fiscal 2021, 81% of our
revenue was derived from distributors (and 58% of our revenue was derived from our three largest
distributors). As we execute our indirect sales strategy, we must manage the potential conflicts that may
arise with our direct sales efforts. For example, conflicts with a distributor may arise when a customer
begins purchasing directly from us rather than through the distributor. The inability to successfully execute
or manage a multi- channel sales strategy could impede our future growth. In addition, relationships
with our distributors often involve the use of price protection and inventory return rights. This often
requires a significant amount of sales management’s time and system resources to manage properly.

We do not have long-term commitments from our customers

Our customers regularly evaluate alternative sources of supply in order to diversify their supplier

base, which increases their negotiating leverage with us and protects their ability to secure these
components. We believe that any expansion of our customers’ supplier bases could have an adverse
effect on the prices we are able to charge and volume of product that we are able to sell to our customers,
which would negatively affect our revenues and operating results.

Customers may decide not to purchase our products at all, purchase fewer products than they did

in the past, or alter their purchasing patterns, particularly because:

• We do not have material long-term purchase contracts with our customers;

• Substantially all of our sales to date have been made on a purchase order basis, which permits

our customers to cancel, change or delay product purchase commitments with little or no notice to
us and without penalty;

• Some of our customers may have efforts underway to actively diversify their vendor base which

could reduce purchases of our products; and

• Some of our customers have developed or acquired products that compete directly with

products these customers purchase from us, which could affect our customers’ purchasing
decisions in the future.

21

We are subject to increased inventory risks and costs because we build our products based on
forecasts provided by customers before receiving purchase orders for the products

In order to ensure availability of our products for some of our largest customers, we start the
manufacturing of our products in advance of receiving purchase orders based on forecasts provided by
these customers. However, these forecasts do not represent binding purchase commitments and we
do not recognize sales for these products until they are shipped to the customer. As a result, we incur
inventory and manufacturing costs in advance of anticipated sales. Because demand for our products
may not materialize, manufacturing based on forecasts subjects us to increased risks of high inventory
carrying costs, increased obsolescence and increased operating costs. These inventory risks are
exacerbated when our customers purchase indirectly through contract manufacturers or hold component
inventory levels greater than their consumption rate because this causes us to have less visibility
regarding the accumulated levels of inventory for such customers. A resulting write-off of unusable or
excess inventories would adversely affect our operating results.

Our products are complex and may contain errors which could lead to liability, an increase in
our costs and/or a reduction in our revenues

Our products are complex and may contain errors, particularly when first introduced and/or when

new versions are released. Our products are increasingly designed in more complex processes, including
higher levels of software and hardware integration in modules and system-level solutions and/or
include elements provided by third parties which further increase the risk of errors. We rely primarily on
our in-house testing personnel to design test operations and procedures to detect any errors or
vulnerabilities prior to delivery of our products to our customers.

Should problems occur in the operation or performance of our products, we may experience
delays in meeting key introduction dates or scheduled delivery dates to our customers. These errors
could also cause significant re-engineering costs, the diversion of our engineering personnel’s attention
from our product development efforts and cause significant customer relations and business reputation
problems. Any defects could result in refunds, product replacement, product recall or other liability.
Any of the foregoing could impose substantial costs and harm our business.

Product liability, data breach or cyber liability claims may be asserted with respect to our products.
Many of our products focus on wireless connectivity and the IoT market and such connectivity may make
these products particularly susceptible to cyber-attacks. Our products are typically sold at prices that
are significantly lower than the cost of the end-products into which they are incorporated. A defect, failure
or vulnerability in our product could cause failure in our customer’s end-product, so we could face
claims for damages that are disproportionately higher than the revenues and profits we receive from
the products involved. Furthermore, product liability risks are particularly significant with respect to
medical and automotive applications because of the risk of serious harm to users of these end-products.
There can be no assurance that any insurance we maintain will sufficiently protect us from such
claims.

We may be subject to information technology failures that could damage our reputation,
business operations and financial condition

We rely on information technology for the effective operation of our business. Our systems are

subject to damage or interruption from a number of potential sources, including natural disasters,
accidents, power disruptions, telecommunications failures, acts of terrorism or war, computer viruses,
theft, physical or electronic break-ins, cyber-attacks, sabotage, vandalism, or similar events or disruptions.
Our security measures may not detect or prevent such security breaches. Any such compromise of
our information security could result in the theft or unauthorized publication or use of our confidential
business or proprietary information, result in the unauthorized release of customer, supplier or employee
data, result in a violation of privacy or other laws, expose us to a risk of litigation or damage our
reputation. In addition, our inability to use or access information systems at critical points in time could
unfavorably impact the timely and efficient operation of our business, which could negatively affect our
business and operating results.

22

Third parties with which we conduct business, such as foundries, assembly and test contractors,

distributors and customers, have access to certain portions of our sensitive data. In the event that
these third parties do not properly safeguard our data that they hold, security breaches could result
and negatively impact our reputation, business operations and financial results. Additionally, a successful
cyber-attack against one of these third-parties’ information technology systems may disrupt our
supply chain.

Our customers require our products to undergo a lengthy and expensive qualification process
without any assurance of product sales

Prior to purchasing our products, our customers require that our products undergo an extensive
qualification process, which involves testing of the products in the customer’s system as well as rigorous
reliability testing. This qualification process may continue for six months or longer. However, qualification
of a product by a customer does not ensure any sales of the product to that customer. Even after
successful qualification and sales of a product to a customer, a subsequent revision to the product or
software, changes in the IC’s manufacturing process or the selection of a new supplier by us may require
a new qualification process, which may result in delays and in us holding excess or obsolete inventory.
After our products are qualified, it can take an additional six months or more before the customer
commences volume production of components or devices that incorporate our products. Despite these
uncertainties, we devote substantial resources, including design, engineering, sales, marketing and
management efforts, toward qualifying our products with customers in anticipation of sales. If we are
unsuccessful or delayed in qualifying any of our products with a customer, such failure or delay would
preclude or delay sales of such product to the customer, which may impede our growth and cause our
business to suffer.

Our inability to manage growth could materially and adversely affect our business

Our past growth has placed, and any future growth of our operations will continue to place, a

significant strain on our management personnel, systems and resources. We anticipate that we will
need to implement a variety of new and upgraded sales, operational and financial enterprise-wide
systems, information technology infrastructure, procedures and controls, including the improvement of
our accounting and other internal management systems to manage this growth and maintain compliance
with regulatory guidelines, including Sarbanes-Oxley Act requirements. To the extent our business
grows, our internal management systems and processes will need to improve to ensure that we remain
in compliance. We also expect that we will need to continue to expand, train, manage and motivate
our workforce. All of these endeavors will require substantial management effort, and we anticipate that
we will require additional management personnel and internal processes to manage these efforts and
to plan for the succession from time to time of certain persons who have been key management and
technical personnel. If we are unable to effectively manage our expanding global operations, including
our international headquarters in Singapore, our business could be materially and adversely affected.

We are subject to risks relating to product concentration

We derive a substantial portion of our revenues from a limited number of products, and we expect
these products to continue to account for a large percentage of our revenues in the near term. Continued
market acceptance of these products, is therefore, critical to our future success. In addition,
substantially all of our products that we have sold include technology related to one or more of our
issued U.S. patents. If these patents are found to be invalid or unenforceable, our competitors could
introduce competitive products that could reduce both the volume and price per unit of our products. Our
business, operating results, financial condition and cash flows could therefore be adversely affected
by:

• A decline in demand for any of our more significant products;

• Failure of our products to achieve continued market acceptance;

• Competitive products;

23

• New technological standards or changes to existing standards that we are unable to address

with our products;

• A failure to release new products or enhanced versions of our existing products on a timely

basis; and

• The failure of our new products to achieve market acceptance.

Any dispositions could harm our financial condition

On April 22, 2021, we entered into an Asset Purchase Agreement pursuant to which Skyworks

Solutions, Inc. agreed to acquire certain assets, rights, and properties, and assume certain liabilities,
comprising our infrastructure and automotive business for $2.75 billion in cash. The transaction closed
on July 26, 2021. This disposition and any other disposition of a business or product line would entail a
number of risks that could materially and adversely affect our business and operating results, including:

• Diversion of management’s time and attention from our core business;

• Difficulties separating the divested business;

• Risks to relations with customers who previously purchased products from our disposed product

line;

• Reduced leverage with suppliers due to reduced aggregate volume;

• Risks related to employee relations;

• Risks that the disposition is not completed on the expected timeline, or at all;

• Risks associated with the transfer and licensing of intellectual property;

• Risks that we do not realize the anticipated benefits from the disposition;

• Risks from third-party claims arising out of the disposition;

• Security risks and other liabilities related to the transition services provided in connection with

the disposition;

• Tax issues associated with dispositions; and

• Disposition-related disputes, including disputes over earn-outs and escrows.

Most of our current manufacturers, assemblers, test service providers, distributors and
customers are concentrated in the same geographic region, which increases the risk that a
natural disaster, epidemic, labor strike, war or political unrest could disrupt our operations or
sales

Most of our foundries and several of our assembly and test subcontractors’ sites are located in
Taiwan and most of our other foundry, assembly and test subcontractors are located in the Pacific Rim
region. In addition, many of our customers are located in the Pacific Rim region. The risk of
earthquakes in Taiwan and the Pacific Rim region is significant due to the proximity of major earthquake
fault lines in the area. Earthquakes, tsunamis, fire, flooding, lack of water or other natural disasters,
an epidemic such as the current COVID-19 outbreak, political unrest, war, labor strikes or work stoppages
in countries where our semiconductor manufacturers, assemblers and test subcontractors are located,
likely would result in the disruption of our foundry, assembly or test capacity. There can be no
assurance that alternate capacity could be obtained on favorable terms, if at all.

A natural disaster, epidemic, labor strike, war or political unrest where our customers’ facilities are

located would likely reduce our sales to such customers. In addition, a significant portion of the assembly
and testing of our products occurs in South Korea. Any disruption resulting from these events, including
the COVID-19 pandemic, could also cause significant delays in shipments of our products until we
are able to shift our manufacturing, assembling or testing from the affected subcontractor to another
third-party vendor. If the COVID-19 pandemic continues to progress in ways that significantly disrupt the

24

manufacture, shipment and sales of our products or the products of our customers, this may materially
negatively impact our operating results for subsequent periods. For example, if the travel restrictions
or business shutdowns or slowdowns continue for an extended period of time in Taiwan, South Korea
or the other countries in which our current manufacturers, assemblers, test service providers, distributors
and customers are located, we may experience delays in product production, a decreased ability to
support our customers, reduced design win activity, and overall lack of productivity. Our customers may
also experience closures of their manufacturing facilities or inability to obtain other components,
either of which could negatively impact demand for our solutions.

The semiconductor manufacturing process is highly complex and, from time to time,
manufacturing yields may fall below our expectations, which could result in our inability to
satisfy demand for our products in a timely manner and may decrease our gross profit due to
higher unit costs

The manufacturing of our products is a highly complex and technologically demanding process.

Although we work closely with our foundries and assemblers to minimize the likelihood of reduced
manufacturing yields, we have from time to time experienced lower than anticipated manufacturing yields.
Changes in manufacturing processes or the inadvertent use of defective or contaminated materials
could result in lower than anticipated manufacturing yields or unacceptable performance deficiencies,
which could lower our gross profit. If our foundries fail to deliver fabricated silicon wafers of satisfactory
quality in a timely manner, we will be unable to meet our customers’ demand for our products in a
timely manner, which would adversely affect our operating results and damage our customer relationships.

We depend on our customers to support our products, and some of our customers offer
competing products

We rely on our customers to provide hardware, software, intellectual property indemnification and

other technical support for the products supplied by our customers. If our customers do not provide the
required functionality or if our customers do not provide satisfactory support for their products, the
demand for these devices that incorporate our products may diminish or we may otherwise be materially
adversely affected. Any reduction in the demand for these devices would significantly reduce our
revenues.

In certain products, some of our customers offer their own competitive products. These customers

may find it advantageous to support their own offerings in the marketplace in lieu of promoting our
products.

We have limited resources compared to some of our current and potential competitors and we
may not be able to compete effectively and increase market share

Some of our current and potential competitors have longer operating histories, significantly greater

resources and name recognition and a larger base of customers than we have. As a result, these
competitors may have greater credibility with our existing and potential customers. They also may be able
to adopt more aggressive pricing policies and devote greater resources to the development, promotion
and sale of their products than we can to ours. In addition, some of our current and potential
competitors have already established supplier or joint development relationships with the decision
makers at our current or potential customers. These competitors may be able to leverage their existing
relationships to discourage their customers from purchasing products from us or persuade them to
replace our products with their products. Our competitors may also offer bundled solutions offering a
more complete product despite the technical merits or advantages of our products. These competitors
may elect not to support our products which could complicate our sales efforts. We also face increased
competition as a result of China actively promoting its domestic semiconductor industry through
policy changes and investment. These actions, as well as China-U.S. trade barriers, may restrict our
participation in the China market or may prevent us from competing effectively with Chinese companies
or companies from other countries that China favors over the United States. Furthermore, our current
or potential competitors may be acquired by third parties with greater available resources and the ability
to initiate or withstand substantial price competition, which may include price concessions, delayed

25

payment terms, financing terms, or other terms and conditions that are more enticing to potential
customers. These and other competitive pressures may prevent us from competing successfully against
current or future competitors, and may materially harm our business. Competition could decrease our
prices, reduce our sales, lower our gross profit and/or decrease our market share.

Changes in the privacy and data security/protection laws could have an adverse effect on our
operations

Federal, state and international privacy-related or data protection laws and regulations could have

an adverse effect on our operations. Complying with these laws and the possibility of proceedings
against us by governmental entities or others in relation to these laws could increase operational costs.
In May 2018, the European Union’s General Data Protection Regulation (“GDPR”) went into effect,
replacing the EU’s 1995 Data Protection Directive. The costs of compliance with the GDPR and the
potential for fines and penalties in the event of a breach of the GDPR may have an adverse effect on
our operations.

Our products must conform to industry standards and technology in order to be accepted by
end users in our markets

Generally, our products comprise only a part of a device. All components of such devices must

uniformly comply with industry standards in order to operate efficiently together. We depend on
companies that provide other components of the devices to support prevailing industry standards.
Many of these companies are significantly larger and more influential in affecting industry standards
than we are. Some industry standards may not be widely adopted or implemented uniformly, and
competing standards may emerge that may be preferred by our customers or end users. If larger
companies do not support the same industry standards that we do, or if competing standards emerge,
market acceptance of our products could be adversely affected which would harm our business.

Products for certain applications are based on industry standards that are continually evolving. Our

ability to compete in the future will depend on our ability to identify and ensure compliance with these
evolving industry standards. The emergence of new industry standards could render our products
incompatible with products developed by other suppliers. As a result, we could be required to invest
significant time and effort and to incur significant expense to redesign our products to ensure compliance
with relevant standards. If our products are not in compliance with prevailing industry standards for a
significant period of time, we could miss opportunities to achieve crucial design wins. For example, the
IoT market is relatively new and is continuously evolving. Furthermore, products in the IoT market
frequently require interoperability across multiple standards. We may need to adjust our portfolio to
meet the needs of this evolving market through acquisitions or significant new investments in research
and development.

Our pursuit of necessary technological advances may require substantial time and expense. We
may not be successful in developing or using new technologies or in developing new products or product
enhancements that achieve market acceptance. If our products fail to achieve market acceptance, our
growth prospects, operating results and competitive position could be adversely affected.

Intellectual Property Risks

Significant litigation over intellectual property in our industry may cause us to become involved
in costly and lengthy litigation which could adversely affect our business

The semiconductor and software industries have experienced significant litigation involving patents

and other intellectual property rights. From time to time, third parties, including non-practicing entities,
allege intellectual property infringement by our products, our customers’ products, or products using
technologies or communications standards used in our industry. We also receive communications
from customers or suppliers requesting indemnification for allegations brought against them by third
parties. Some of these allegations have resulted, and may result in the future, in our involvement in
litigation. We have certain contractual obligations to defend and indemnify our customers from certain

26

infringement claims. We also have been involved in litigation to protect our intellectual property rights in
the past and may become involved in such litigation again in the future.

Given the unpredictable nature of litigation and the complexity of the technology, we may not

prevail in any such litigation. Legal proceedings could subject us to significant liability, invalidate our
proprietary rights, or harm our businesses and our ability to compete. Legal proceedings initiated by us
to protect our intellectual property rights could also result in counterclaims or countersuits against us.
Any litigation, regardless of its outcome or merit, could be time-consuming and expensive to resolve and
could divert our management’s time and attention. Intellectual property litigation also could force us to
take specific actions, including:

• Cease using, selling or manufacturing certain products, services or processes;

• Attempt to obtain a license, which license may require the payment of substantial royalties or

may not be available on reasonable terms or at all;

• Incur significant costs, time delays and lost business opportunities to develop alternative

technologies or redesign products; or

• Pursue legal remedies with third parties to enforce our indemnification rights, which may not

adequately protect our interests.

We may be unable to protect our intellectual property, which would negatively affect our ability
to compete

Our products rely on our proprietary technology, and we expect that future technological advances
made by us will be critical to sustain market acceptance of our products. Therefore, we believe that the
protection of our intellectual property rights is and will continue to be important to the success of our
business. We rely on a combination of patent, copyright, trademark and trade secret laws and restrictions
on disclosure to protect our intellectual property rights. We also enter into confidentiality or license
agreements with our employees, consultants, intellectual property providers and business partners,
and control access to and distribution of our documentation and other proprietary information. Despite
these efforts, unauthorized parties may attempt to copy or otherwise obtain and use our proprietary
technology. Monitoring unauthorized use of our technology is difficult, and we cannot be certain that
the steps we have taken will prevent unauthorized use of our technology, particularly in foreign countries
where the laws may not protect our proprietary rights as fully as in the United States. We cannot be
certain that patents will be issued as a result of our pending applications nor can we be certain that any
issued patents would protect or benefit us or give us adequate protection from competing products.
For example, issued patents may be circumvented or challenged and declared invalid or unenforceable.
We also cannot be certain that others will not develop effective competing technologies on their own.

Our products incorporate technology licensed from third parties

We incorporate technology (including software) licensed from third parties in our products. We
could be subjected to claims of infringement regardless of our lack of involvement in the development
of the licensed technology. Although a third-party licensor is typically obligated to indemnify us if the
licensed technology infringes on another party’s intellectual property rights, such indemnification is
typically limited in amount and may be worthless if the licensor becomes insolvent. See Significant
litigation over intellectual property in our industry may cause us to become involved in costly and lengthy
litigation which could seriously harm our business. Furthermore, any failure of third-party technology
to perform properly would adversely affect sales of our products incorporating such technology.

Liquidity and Credit Risks

We are subject to credit risks related to our accounts receivable

We do not generally obtain letters of credit or other security for payment from customers, distributors

or contract manufacturers. Accordingly, we are not protected against accounts receivable default or
bankruptcy by these entities. Our ten largest customers or distributors represent a substantial majority

27

of our accounts receivable. If any such customer or distributor, or a material portion of our smaller
customers or distributors, were to become insolvent or otherwise not satisfy their obligations to us, we
could be materially harmed.

Our convertible senior notes could adversely affect our operating results and financial condition

On January 1, 2022, a condition regarding early conversion of our 2025 convertible senior notes

(the “2025 Notes”) was met, and as a result, holders may convert their notes at any time during the
quarter ending March 31, 2022. On January 2, 2022, we irrevocably elected cash settlement for the
principal amount of the 2025 Notes. If we do not have adequate cash available to settle the principal
amount of the 2025 Notes, we could seek to raise additional funds through debt or equity capital. However,
additional funds may not be available on terms acceptable to us, or at all. We intend to settle any
excess value in shares in the event of a conversion. Shares issued to settle any excess value may
result in immediate, and potentially material, dilution to the ownership interests of our existing
stockholders. Any sales in the public market of our common stock issuable upon such conversion
could adversely affect prevailing market prices of our common stock.

The principal balance of the convertible senior notes was separated into liability and equity

components, which were recorded initially at fair value. The excess of the principal amount of the
liability component over its carrying amount represents the debt discount, which is accreted to interest
expense over the term of the notes using the effective interest method. Accordingly, we have reported
higher interest expense because of the recognition of both the debt discount amortization and the
notes’ coupon interest.

Our debt could adversely affect our operations and financial condition

We believe we have the ability to service our debt, but our ability to make the required payments
thereunder when due depends upon our future performance, which will be subject to general economic
conditions, industry cycles and other factors affecting our operations, including risk factors described
herein, such as the potential implications of the COVID-19 pandemic, many of which are beyond our
control. Our credit facility also contains covenants, including financial covenants. If we breach any of the
covenants under our credit facility and do not obtain appropriate waivers, then, subject to any applicable
cure periods, our outstanding indebtedness thereunder could be declared immediately due and
payable.

We could seek to raise additional debt or equity capital in the future, but additional capital may
not be available on terms acceptable to us, or at all

We believe that our existing cash, cash equivalents, investments and credit under our credit facility
will be sufficient to meet our working capital needs, capital expenditures, investment requirements and
commitments for at least the next 12 months. However, our ability to borrow further under the credit facility
is dependent upon our ability to satisfy various conditions, covenants and representations. It is possible
that we may need to raise additional funds to finance our activities or to facilitate acquisitions of
other businesses, products, intellectual property or technologies. We believe we could raise these
funds, if needed, by selling equity or debt securities to the public or to selected investors. In addition,
even though we may not need additional funds, we may still elect to sell additional equity or debt securities
or obtain credit facilities for other reasons. However, we may not be able to obtain additional funds on
favorable terms, or at all, particularly during financial market instability related to the COVID-19 pandemic.
If we decide to raise additional funds by issuing equity or convertible debt securities, the
ownership percentages of existing shareholders would be reduced.

Stock and Governance Risks

Our stock price may be volatile

The market price of our common stock has been volatile in the past and may be volatile in the
future. The market price of our common stock may be significantly affected by the following factors:

• Actual or anticipated fluctuations in our operating results;

• Changes in financial estimates by securities analysts or our failure to perform in line with such

estimates;

• Changes in market valuations of other technology companies, particularly semiconductor

companies;

• Announcements by us or our competitors of significant technical innovations, acquisitions,

strategic partnerships, joint ventures or capital commitments;

• Introduction of technologies or product enhancements that reduce the need for our products;

• The loss of, or decrease in sales to, one or more key customers;

• A large sale of stock by a significant shareholder;

• Dilution from the issuance of our stock in connection with acquisitions;

• The addition or removal of our stock to or from a stock index fund;

• Departures of key personnel;

• The required expensing of stock awards; and

• Reporting revenue under ASC Topic 606, Revenue from Contracts with Customers.

The stock market has experienced extreme volatility that often has been unrelated to the
performance of particular companies. These market fluctuations may cause our stock price to fall
regardless of our performance.

Provisions in our charter documents and Delaware law could prevent, delay or impede a change
in control of us and may reduce the market price of our common stock

Provisions of our certificate of incorporation and bylaws could have the effect of discouraging,
delaying or preventing a merger or acquisition that a stockholder may consider favorable. For example,
our certificate of incorporation and bylaws provide for:

• The division of our Board of Directors into three classes to be elected on a staggered basis, one

class each year;

• The ability of our Board of Directors to issue shares of our preferred stock in one or more series

without further authorization of our stockholders;

• A prohibition on stockholder action by written consent;

• Elimination of the right of stockholders to call a special meeting of stockholders;

• A requirement that stockholders provide advance notice of any stockholder nominations of

directors or any proposal of new business to be considered at any meeting of stockholders; and

• A requirement that a supermajority vote be obtained to amend or repeal certain provisions of

our certificate of incorporation.

We also are subject to the anti-takeover laws of Delaware which may discourage, delay or prevent
someone from acquiring or merging with us, which may adversely affect the market price of our common
stock.

Item 2. Properties

Our corporate headquarters, housing engineering, sales and marketing, administration and test
operations, is located in Austin, Texas. Our headquarters facilities consist of two buildings, which we
own, that are located on land which we have leased through 2099. The buildings contain approximately
441,000 square feet of floor space, of which approximately 155,000 square feet were leased to other
tenants. In addition to these properties, we lease smaller facilities in various locations in the United
States, Canada, China, Denmark, Finland, France, Germany, Hungary, India, Italy, Japan, Norway,
Singapore, South Korea, Taiwan and the United Kingdom for engineering, sales and marketing,
administrative and manufacturing support activities. We believe that these facilities are suitable and
adequate to meet our current operating needs.

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

Operations

The following discussion and analysis of financial condition and results of operations should be

read in conjunction with the Consolidated Financial Statements and related notes thereto included
elsewhere in this report. This discussion contains forward-looking statements. Please see the “Cautionary
Statement” and “Risk Factors” above for discussions of the uncertainties, risks and assumptions
associated with these statements. Our fiscal year-end financial reporting periods are a 52- or 53-week
fiscal year that ends on the Saturday closest to December 31. Fiscal 2021 had 52 weeks. Fiscal 2020 had
53 weeks with the extra week occurring in the first quarter of the year. Fiscal 2019 had 52 weeks.
Fiscal 2021, 2020 and 2019 ended on January 1, 2022, January 2, 2021 and December 28, 2019,
respectively.

Impact of COVID-19

A new strain of novel coronavirus which causes a severe respiratory disease (“COVID-19”) was
identified in 2019, and subsequently declared a worldwide pandemic by the World Health Organization.
We implemented a response plan and continued operations while largely transitioning our global
workforce to a remote work model. The third parties that perform our semiconductor manufacturing,
assembly, packaging and testing have generally remained operational. The extent of the impact of the
COVID-19 pandemic on our operational and financial performance will depend on future developments,
including the duration, severity and spread of the pandemic, related restrictions on travel and
transportation and other actions that may be taken by governmental authorities, the impact to the
business of our suppliers or customers, and other items identified under “Risk Factors” above, all of
which are uncertain and cannot be predicted. An extended period of global supply chain and economic
disruption could materially affect our business, results of operations, access to sources of liquidity
and financial condition.

Overview

We are a leader in secure, intelligent wireless technology for a more connected world. Our
integrated hardware and software platform, intuitive development tools, industry leading ecosystem
and robust support enable customers in building advanced industrial, commercial, home and life
applications. We make it easy for developers to solve complex wireless challenges throughout the
product lifecycle and get to market quickly with innovative solutions that transform industries, grow
economies and improve lives. We provide analog-intensive, mixed-signal solutions for use in a variety
of electronic products in a broad range of applications for the Internet of Things (IoT) including connected
home and security, industrial automation and control, smart metering, smart lighting, commercial
building automation, consumer electronics, asset tracking and medical instrumentation.

As a fabless semiconductor company, we rely on third-party semiconductor fabricators in Asia,
and to a lesser extent the United States and Europe, to manufacture the silicon wafers that reflect our
IC designs. Each wafer contains numerous die, which are cut from the wafer to create a chip for an IC. We
rely on third parties in Asia to assemble, package, and, in most cases, test these devices and ship
these units to our customers. Testing performed by such third parties facilitates faster delivery of
products to our customers (particularly those located in Asia), shorter production cycle times, lower
inventory requirements, lower costs and increased flexibility of test capacity.

The sales cycle for our ICs can be as long as 12 months or more. An additional three to six months

or more are usually required before a customer ships a significant volume of devices that incorporate
our ICs. Due to this lengthy sales cycle, we typically experience a significant delay between incurring
research and development and selling, general and administrative expenses, and the corresponding
sales. Consequently, if sales in any quarter do not occur when expected, expenses and inventory
levels could be disproportionately high, and our operating results for that quarter and, potentially, future
quarters would be adversely affected. Moreover, the amount of time between initial research and
development and commercialization of a product, if ever, can be substantially longer than the sales
cycle for the product. Accordingly, if we incur substantial research and development costs without

33

developing a commercially successful product, our operating results, as well as our growth prospects,
could be adversely affected.

Because some of our ICs are designed for use in consumer products, we expect that the demand
for our products will be typically subject to some degree of seasonal demand. However, rapid changes
in our markets and across our product areas make it difficult for us to accurately estimate the impact
of seasonal factors on our business.

Discontinued Operations

On April 22, 2021, we entered into an Asset Purchase Agreement pursuant to which Skyworks

Solutions, Inc. agreed to acquire certain assets, rights, and properties, and assume certain liabilities,
comprising our infrastructure and automotive business for $2.75 billion in cash. The sale was completed
pursuant to the terms of the Agreement on July 26, 2021. The results of operations of the sold
component have been presented in the accompanying consolidated financial statements as discontinued
operations and, therefore, are excluded from the following discussion of the results of our continuing
operations.

Current Period Highlights of Continuing Operations

Revenues increased $209.9 million in fiscal 2021 compared to fiscal 2020 due to increased

demand for our products. Gross profit increased $130.6 million during the same period due primarily to
increased product sales. Gross margin increased to 59.0% in fiscal 2021 compared to 57.7% in fiscal
2020 primarily due to variations in product mix. Operating expenses increased $56.3 million in fiscal 2021
compared to fiscal 2020 due primarily to increased personnel-related expenses, new product
introduction costs, occupancy costs and amortization of intangible assets. Operating loss in fiscal 2021
was $32.8 million compared to $107.1 million in fiscal 2020.

We ended fiscal 2021 with $2.0 billion in cash, cash equivalents and short-term investments. Net

cash provided by operating activities was $91.2 million during fiscal 2021. Accounts receivable were
$98.3 million at January 1, 2022, representing 42 days sales outstanding (DSO). Inventory was
$49.3 million at January 1, 2022, representing 55 days of inventory (DOI). In fiscal 2021, we repurchased
6.5 million shares of our common stock for an aggregate cost of $1.15 billion, including 4.0 million
shares through a tender offer, 1.7 million shares through an ASR agreement and 0.8 million shares
through our existing share repurchase program. During fiscal 2021, we paid $140.6 million in cash and
issued 528,022 shares of common stock in connection with the redemption of the remaining principal
of our 2022 convertible senior notes.

Through acquisitions and internal development efforts, we have continued to diversify our portfolio

and introduce new products and solutions with added functionality and integration. In fiscal 2021, we
introduced a 3D virtual smart home platform that takes users through innovative smart home solutions,
various applicable protocols, and ecosystem connections; Z-Wave 800 system-on-chips (SoCs) and
modules for the Z-Wave smart home and automation ecosystem; Custom Part Manufacturing Service
(CPMS) to support IoT companies with the implementation of ‘Zero Trust’ security architectures to meet
emerging cybersecurity standards; the Unify Software Development Kit (SDK), which provides the
common building blocks for connectivity across IoT ecosystems; new sub-1-GHz SoCs delivering
wireless solutions that combine long-range RF and energy efficiency with certified ARM PSA Level 3
security; a fully integrated, certified Wi-SUN® solution simplifying Low Power Wide Area Network
(LPWAN) deployment for smart cities; wireless solutions for development of Matter end products that
support Thread, Wi-Fi, and Bluetooth protocols; and a new 32-bit MCU on our award-winning xG22
platform for IoT edge applications. We plan to continue introducing products that increase the content we
provide for existing applications, thereby enabling us to serve markets we do not currently address
and expand our total available market opportunity.

During fiscal 2021, 2020 and 2019, we had no customer that represented more than 10% of our

revenues. In addition to direct sales to customers, some of our end customers purchase products
indirectly from us through distributors and contract manufacturers. An end customer purchasing through
a contract manufacturer typically instructs such contract manufacturer to obtain our products and

34

incorporate such products with other components for sale by such contract manufacturer to the end
customer. Although we actually sell the products to, and are paid by, the distributors and contract
manufacturers, we refer to such end customer as our customer. Three of our distributors who sell to our
customers, Arrow Electronics, Edom Technology and Sekorm, each represented 28%, 18% and 12%
of our revenues during fiscal 2021, 28%, 19% and 14% of our revenues during fiscal 2020, and 26%,
18% and 10% of our revenues during fiscal 2019, respectively.

The percentage of our revenues derived from outside of the United States was 86% in fiscal 2021,

88% in fiscal 2020 and 87% in fiscal 2019. All of our revenues to date have been denominated in U.S.
dollars. We believe that a majority of our revenues will continue to be derived from customers outside of
the United States.

Results of Operations

The following describes the line items set forth in our Consolidated Statements of Income:

Revenues. Revenues are generated predominately by sales of our products. Our revenues are

subject to variation from period to period due to the volume of shipments made within a period, the mix
of products we sell and the prices we charge for our products.

Cost of Revenues. Cost of revenues includes the cost of purchasing finished silicon wafers

processed by independent foundries; costs associated with assembly, test and shipping of those
products; costs of personnel and equipment associated with manufacturing support, logistics and quality
assurance; costs of software royalties, other intellectual property license costs and certain acquired
intangible assets; and an allocated portion of our occupancy costs. Our gross margin fluctuates
depending on product mix, manufacturing yields, inventory valuation adjustments, average selling
prices and other factors.

Research and Development. Research and development expense consists primarily of
personnel-related expenses, including stock-based compensation, as well as new product masks,
external consulting and services costs, equipment tooling, equipment depreciation, amortization of
intangible assets and an allocated portion of our occupancy costs. Research and development activities
include the design of new products, refinement of existing products and design of test methodologies
to ensure compliance with required specifications.

Selling, General and Administrative. Selling, general and administrative expense consists
primarily of personnel-related expenses, including stock-based compensation, as well as an allocated
portion of our occupancy costs, sales commissions to independent sales representatives, amortization of
intangible assets, professional fees, legal fees, and promotional and marketing expenses.

Interest Income and Other, Net.

Interest income and other, net reflects interest earned on our
cash, cash equivalents and investment balances, foreign currency remeasurement adjustments, and
other non-operating income and expenses.

Interest Expense.

Interest expense consists of interest on our short and long-term obligations,

including our convertible senior notes and credit facility. Interest expense on our convertible senior notes
includes contractual interest, amortization of the debt discount and amortization of debt issuance
costs.

Equity-method Earnings. Equity-method earnings represents income or loss on our equity-

method investment.

Provision (Benefit) for Income Taxes. Provision (benefit) for income taxes includes both
domestic and foreign income taxes at the applicable tax rates adjusted for non-deductible expenses,
research and development tax credits and other permanent differences.

The change in revenues in fiscal 2021 was due to increased demand for our IoT products. Unit
shipment volumes of our products increased by 37.1% while average selling prices increased by 2.7%
compared to fiscal 2020. The average selling prices of our products may fluctuate significantly from
period to period due to changes in product mix, pricing decisions and other factors. In general, as our
products become more mature, we expect to experience decreases in average selling prices.

Gross profit increased in fiscal 2021 due primarily to increased product sales. Gross margin

increased in fiscal 2021 primarily due to variations in product mix.

We may experience variations in the average selling prices of certain of our products. Increases in
average selling prices may occur during periods of increased demand, but such demand may be short-
lived and could be accompanied by higher product costs. Declines in average selling prices create
downward pressure on gross margin and may be offset to the extent we are able to introduce higher

36

margin new products and gain market share with our products; reduce costs of existing products
through improved design; achieve lower production costs from our wafer suppliers and third-party
assembly and test subcontractors; achieve lower production costs per unit as a result of improved yields
throughout the manufacturing process; or reduce logistics costs.

The increase in research and development expense in fiscal 2021 was primarily due to increases

of $23.9 million for personnel-related expenses, $8.8 million for new product introduction costs,
$2.1 million for occupancy costs and $1.0 million for the amortization of intangible assets. The decrease
in research and development expense as a percent of revenues in fiscal 2021 was due to our increased
revenues. We expect that research and development expense will increase in absolute dollars in the
first quarter of 2022 compared to the fourth quarter of 2021.

Interest Income and Other, Net

Interest income and other, net in fiscal 2021 was $5.7 million compared to $9.0 million in fiscal
2020. The decrease in interest income and other, net in fiscal 2021 was primarily due to lower interest
rates on the underlying instruments.

Interest Expense

Interest expense in fiscal 2021 was $31.0 million compared to $34.1 million in fiscal 2020. The

decrease in interest expense in fiscal 2021 was primarily due to a net decrease of $2.7 million in
interest resulting from the reduction in the aggregate balance of convertible notes outstanding and a
decrease in borrowings from our existing credit facility.

(23.1)% 11.0%

The provision for income taxes for fiscal 2021 compared to the benefit from income taxes in fiscal

2020 was primarily due to the reallocation of income tax benefit from continuing operations to discontinued
operations under Financial Accounting Standards Board (FASB) Accounting Standards Update
(ASU) 2019-12, Simplifying the Accounting for Income Taxes, and an increase in the beginning of year

valuation allowance on deferred tax assets for state attribute carryforwards. Additionally, tax expense
on the gain from the divestiture of the infrastructure and automotive business to Skyworks Solutions of
$346.9 million was recorded in discontinued operations for the period, net of tax benefits associated with
discontinued operations before the gain on sale of $7.2 million for fiscal 2021.

Equity-method Earnings

Equity-method earnings in fiscal 2021 were $13.7 million compared to $2.1 million in fiscal 2020.

The increase in equity-method earnings in fiscal 2021 was due to an increase in the unrealized gain on
an equity-method investment.

increase in interest expense in fiscal 2020 was primarily due to a net increase of $8.0 million in interest
resulting from an increase in the aggregate balance of notes outstanding and a loss of $4.1 million
recorded on the early extinguishment of a portion of the 2022 Notes.

Liquidity and Capital Resources

Our principal sources of liquidity as of January 1, 2022 consisted of $2.0 billion in cash, cash

equivalents and short-term investments, of which approximately $730.7 million was held by our U.S.
entities. The remaining balance was held by our foreign subsidiaries. Our cash equivalents and short-term
investments consisted of government debt securities, which include agency bonds, agency discount
notes, municipal bonds and U.S. government securities; corporate debt securities, which include
asset-backed securities, corporate bonds, certificates of deposit and commercial paper; and money
market funds. Our long-term investments consisted of auction-rate securities.

Operating Activities

Net cash provided by operating activities was $91.2 million during fiscal 2021, compared to net
cash used of $8.8 million during fiscal 2020. Operating cash flows during fiscal 2021 reflect our net
income of $2.1 billion, adjustments of $(2.0) billion for income from discontinued operations, depreciation,
amortization, stock-based compensation, equity-method earnings and deferred income taxes, and a
net cash inflow of $20.7 million due to changes in our operating assets and liabilities.

Net cash used in operating activities was $8.8 million during fiscal 2020, compared to net cash
provided of $22.1 million during fiscal 2019. Operating cash flows during fiscal 2020 reflect our net
income of $12.5 million, adjustments of $(2.8) million for income from discontinued operations,
depreciation, amortization, stock-based compensation, equity-method earnings and deferred income
taxes, and a net cash outflow of $18.5 million due to changes in our operating assets and liabilities.

Accounts receivable increased to $98.3 million at January 1, 2022 from $95.2 million at January 2,

2021. The increase in accounts receivable resulted primarily from normal variations in the timing of
collections and billings. Our average DSO was 42 days at January 1, 2022 and 35 days at January 2,
2021.

Inventory increased to $49.3 million at January 1, 2022 from $47.9 million at January 2, 2021. Our

inventory levels will vary based on the availability of supply, and to a lesser extent, the impact of
variations between forecasted demand used for purchasing inventory and actual demand. Our DOI was
55 days at January 1, 2022 and 70 days at January 2, 2021.

Investing Activities

Net cash used in investing activities was $476.7 million during fiscal 2021, compared to net cash

used of $358.3 million during fiscal 2020. The increase in cash outflows was principally due to an
increase in cash outflows of $424.7 million from net purchases and sales of marketable securities in
fiscal 2021, offset by a cash payment of $316.8 million for the acquisition of the Wi-Fi and Bluetooth
business of Redpine Signals in fiscal 2020.

Net cash used in investing activities was $358.3 million during fiscal 2020, compared to net cash

used of $102.8 million during fiscal 2019. The increase in cash outflows was principally due a cash
payment of $316.8 million for the acquisition of a business in fiscal 2020, offset by a decrease in cash
outflows of $57.4 million from net purchases and sales of marketable securities in fiscal 2019.

40

Financing Activities

Net cash used in financing activities was $1.3 billion during fiscal 2021, compared to cash provided
of $200.9 million during fiscal 2020. The increase in cash outflows was principally due to an increase of
$1.1 billion for repurchases of our common stock in fiscal 2021 and $845.0 million in proceeds from
the issuance of debt in fiscal 2020, offset by a decrease of $484.2 million in payments on debt in fiscal
2021. During fiscal 2021, we repurchased 6.5 million shares, including purchases of 4.0 million
shares through a tender offer, 1.7 million shares through an ASR agreement and 0.8 million shares
through our existing share repurchase program.

Net cash provided by financing activities was $200.9 million during fiscal 2020, compared to cash

used of $29.6 million during fiscal 2019. The increase in cash inflows was principally due to $845.0 million
in proceeds from the issuance of debt and a decrease of $10.4 million for repurchases of our common
stock, offset by $623.6 million in payments on debt in fiscal 2020.

Discontinued Operations

Net cash provided by discontinued operations was $2.6 billion during fiscal 2021, compared to net
cash provided of $141.9 million during fiscal 2020. The increase in cash inflows was principally due to
$2.75 billion in proceeds from the sale of our infrastructure and automotive business, offset by a payment
of $252.8 million for incomes taxes on the gain on sale.

Net cash provided by discontinued operations was $141.9 million during fiscal 2020, compared to

net cash provided of $140.4 million during fiscal 2019.

Debt

As of January 1, 2022, our debt included $535 million principal amount of convertible senior notes
(the “2025 Notes”). We also had an undrawn $400 million revolving credit facility. We have an option to
increase the size of the borrowing capacity of the revolving credit facility by up to the greater of an
aggregate of $250 million and 100% of EBITDA, plus an amount that would not cause a secured
leverage ratio to exceed 3.25 to 1.00, subject to certain conditions. On January 1, 2022, a condition
regarding early conversion of the 2025 Notes was met, and as a result, holders have the right to convert
their notes at any time during the quarter ending March 31, 2022. On January 2, 2022, we irrevocably
elected cash settlement for the principal amount of the 2025 Notes.

On January 6, 2021, we issued a notice of redemption for the remaining 2022 convertible senior
notes (the “2022 Notes”). During fiscal 2021, we paid $140.6 million in cash and issued 528,022 shares
of common stock in connection with the redemption of the remaining 2022 Notes. See Note 11, Debt,
to the Consolidated Financial Statements for additional information.

Capital Requirements

Our future capital requirements will depend on many factors, including the rate of sales growth,

market acceptance of our products, the timing and extent of research and development projects,
potential acquisitions of companies or technologies and the expansion of our sales and marketing
activities. We believe our existing cash, cash equivalents, investments, credit under our Credit Facility,
and cash generated from operations are sufficient to meet our short-term and long-term capital
requirements, although we could be required, or could elect, to seek additional funding prior to that
time. We may enter into acquisitions or strategic arrangements in the future which also could require us
to seek additional equity or debt financing.

Contractual Obligations

Our purchase obligations primarily include contractual arrangements in the form of purchase

orders with suppliers. As of January 1, 2022, such purchase obligations were $190.2 million. For a
description of other contractual obligations, see Note 11, Debt, and Note, 12, Leases, to the Consolidated
Financial Statements.

Critical Accounting Policies and Estimates

The preparation of financial statements and accompanying notes in conformity with U.S. generally

accepted accounting principles requires that we make estimates and assumptions that affect the
amounts reported. Changes in facts and circumstances could have a significant impact on the resulting
estimated amounts included in the financial statements. We believe the following critical accounting
policies affect our more complex judgments and estimates.

Inventory valuation—We assess the recoverability of inventories through the application of a set of
methods, assumptions and estimates. In determining net realizable value, we write down inventory that
may be slow moving or have some form of obsolescence, including inventory that has aged more
than 12 months. We also adjust the valuation of inventory when its manufacturing cost exceeds the
estimated selling price less costs of completion, disposal and transportation. We assess the potential
for any unusual customer returns based on known quality or business issues and write-off inventory
losses for scrap or non-saleable material. Inventory not otherwise identified to be written down is
compared to an assessment of our 12-month forecasted demand. The result of this methodology is
compared against the product life cycle and competitive situations in the marketplace to determine the
appropriateness of the resulting inventory levels. Demand for our products may fluctuate significantly
over time, and actual demand and market conditions may be more or less favorable than those that
we project. In the event that actual demand is lower or market conditions are worse than originally
projected, additional inventory write-downs may be required.

Impairment of goodwill and other long-lived assets—We review long-lived assets which are held

and used, including fixed assets and purchased intangible assets, for impairment whenever changes in
circumstances indicate that the carrying amount of the assets may not be recoverable. Such
evaluations compare the carrying amount of an asset to future undiscounted net cash flows expected
to be generated by the asset over its expected useful life and are significantly impacted by estimates of
future prices and volumes for our products, capital needs, economic trends and other factors which
are inherently difficult to forecast. If the asset is considered to be impaired, we record an impairment
charge equal to the amount by which the carrying value of the asset exceeds its fair value determined
by either a quoted market price, if any, or a value determined by utilizing a discounted cash flow technique.

We test our goodwill for impairment annually as of the first day of our fourth fiscal quarter and in
interim periods if certain events occur indicating that the carrying value of goodwill may be impaired.
We assess goodwill for impairment by comparing the fair value of a reporting unit to its carrying amount.
In determining fair value, several valuation methodologies are allowed, although quoted market prices
are the best evidence of fair value. If the fair value of the reporting unit is less than its carrying amount,
we recognize an impairment loss equal to that excess amount.

Acquired intangible assets—When we acquire a business, a portion of the purchase price is

typically allocated to identifiable intangible assets, such as acquired technology and customer
relationships. Fair value of these assets is determined primarily using the income approach, which
requires us to project future cash flows and apply an appropriate discount rate. We amortize intangible
assets with finite lives over their expected useful lives. Our estimates are based upon assumptions
believed to be reasonable but which are inherently uncertain and unpredictable. Assumptions may be
incomplete or inaccurate, and unanticipated events and circumstances may occur. Incorrect estimates
could result in future impairment charges, and those charges could be material to our results of
operations.

Revenue recognition—We recognize revenue when control of the promised goods or services is

transferred to customers, in an amount that reflects the consideration we expect to be entitled to in
exchange for those goods or services. In order to achieve this core principle, we apply a five-step process.
As part of this process, we analyze the performance obligations in a customer contract and estimate
the variable consideration we expect to receive. The evaluation of performance obligations requires that
we identify the promised goods and services in the contract. For contracts that contain more than one
promised good and service, we then must determine whether the promises are capable of being distinct
and if they are separately identifiable from other promises in the contract. Variable consideration
primarily includes sales made to distributors under agreements allowing certain rights of return, referred

42

to as stock rotation, and credits issued to the distributor due to price protection. We estimate variable
consideration at the most likely amount to which we expect to be entitled. We make these estimates
based on available information, including recent sales activity and pricing data. We apply a constraint to
our variable consideration estimate which considers both the likelihood of a return and the amount of
a potential price concession. If our evaluation of performance obligations is incorrect, we may recognize
revenue sooner or later than is appropriate. If our estimates of variable consideration are inaccurate,
we may recognize too much or too little revenue in a period. We may adjust assumptions used to estimate
consideration periodically based on analysis of prior estimates.

Stock-based compensation—We recognize the fair-value of stock-based compensation transactions

in the Consolidated Statements of Income. The fair value of our full-value stock awards (with the
exception of market-based performance awards) equals the fair market value of our stock on the date
of grant. The fair value of our market-based performance awards is estimated at the date of grant using
a Monte-Carlo simulation. The fair value of our stock option and employee stock purchase plan grants
is estimated at the date of grant using the Black-Scholes option pricing model. In addition, we are required
to estimate the expected forfeiture rate of our stock grants and only recognize the expense for those
shares expected to vest. If our actual experience differs significantly from the assumptions used to
compute our stock-based compensation cost, or if different assumptions had been used, we may have
recorded too much or too little stock-based compensation cost. See Note 16, Stock-Based
Compensation, to the Consolidated Financial Statements for additional information.

Income taxes—We are required to calculate income taxes in each of the jurisdictions in which we

operate. This process involves calculating the actual current tax liability together with assessing
temporary differences in recognition of income (loss) for tax and accounting purposes. These differences
result in deferred tax assets and liabilities, which are included in our Consolidated Balance Sheets.
We record a valuation allowance when it is more likely than not that some portion or all of the deferred
tax assets will not be realized. In assessing the need for a valuation allowance, we are required to
estimate the amount of expected future taxable income. Judgment is inherent in this process and
differences between the estimated and actual taxable income could result in a material impact on our
Consolidated Financial Statements.

We recognize liabilities for uncertain tax positions based on a two-step process. The first step
requires us to determine whether the weight of available evidence indicates that the tax position has
met the threshold for recognition. Therefore, we must evaluate whether it is more likely than not that the
position will be sustained on audit, including resolution of any related appeals or litigation processes.
The second step requires us to measure the tax benefit of the tax position taken, or expected to be taken,
in an income tax return as the largest amount that is more than 50% likely of being realized upon
ultimate settlement. This measurement step is inherently complex and requires subjective estimations
of such amounts to determine the probability of various possible outcomes. We re-evaluate the uncertain
tax positions each quarter based on factors including, but not limited to, changes in facts or
circumstances, changes in tax law, expirations of statutes of limitation, effectively settled issues under
audit, and new audit activity. Such a change in recognition or measurement would result in the recognition
of a tax benefit or an additional charge to the tax provision in the period.

Although we believe the measurement of our liabilities for uncertain tax positions is reasonable, no
assurance can be given that the final outcome of these matters will not be different than what is reflected
in the historical income tax provisions and accruals. If additional taxes are assessed as a result of an
audit or litigation, they could have a material effect on our income tax provision and net income in the
period or periods for which that determination is made. We operate within multiple taxing jurisdictions
and are subject to audit in these jurisdictions. These audits can involve complex issues which may require
an extended period of time to resolve and could result in additional assessments of income tax. We
believe adequate provisions for income taxes have been made for all periods.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk

Interest Income

Our investment portfolio includes cash, cash equivalents, short-term investments and long-term

investments. Our main investment objectives are the preservation of investment capital and the
maximization of after-tax returns on our investment portfolio. Our interest income is sensitive to changes
in the general level of U.S. interest rates. Our investment portfolio holdings as January 1, 2022 and
January 2, 2021 yielded less than 100 basis points. A decline in yield to zero basis points on our
investment portfolio holdings as of January 1, 2022 and January 2, 2021 would decrease our future
annual interest income by approximately $3.6 million and $5.2 million, respectively. We believe that our
investment policy, which defines the duration, concentration, and minimum credit quality of the
allowable investments, meets our investment objectives.

Interest Expense

We are exposed to interest rate fluctuations in the normal course of our business, including
through our credit facility. The interest rate on the credit facility consists of a variable rate of interest
and an applicable margin. While we have drawn from the credit facility in the past, we have no borrowings
as of January 1, 2022. If we borrow from the credit facility in the future, we will again be exposed to
interest rate fluctuations.

Foreign currency exchange rate risk

We are exposed to foreign currency exchange rate risk primarily through assets, liabilities and

operating expenses of our subsidiaries denominated in currencies other than the U.S. dollar. Our
foreign subsidiaries are considered to be extensions of the U.S. parent. The functional currency of the
foreign subsidiaries is the U.S. dollar. Accordingly, gains and losses resulting from remeasuring
transactions denominated in currencies other than U.S. dollars are recorded in the Consolidated
Statements of Income. We use foreign currency forward contracts to manage exposure to foreign
exchange risk. Gains and losses on foreign currency forward contracts are recognized in earnings in
the same period during which the hedged transaction is recognized.

Investments in Auction-rate Securities

As of January 1, 2022, we held $6.0 million par value auction-rate securities, all of which have
experienced failed auctions because sell orders exceeded buy orders. We are unable to predict if these
funds will become available before their maturity dates. Additionally, if we determine that a credit-
related decline in the fair value of any of our available-for-sale auction-rate securities has occurred, we
may be required to adjust the carrying value of the investments through an impairment charge.

Item 8. Financial Statements and Supplementary Data

The Financial Statements and supplementary data required by this item are included in Part IV,

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We have performed an evaluation under the supervision and with the participation of our
management, including our Chief Executive Officer (CEO) and Chief Financial Officer (CFO), of the
effectiveness of our disclosure controls and procedures, as defined in Rule 13a-15(e) under the Securities

44

Exchange Act of 1934 (the Exchange Act). Based on that evaluation, our management, including our
CEO and CFO, concluded that our disclosure controls and procedures were effective as of January 1,
2022 to provide reasonable assurance that information required to be disclosed by us in the reports filed
or submitted by us under the Exchange Act is recorded, processed, summarized and reported within
the time periods specified in the SEC’s rules and forms. Such disclosure controls and procedures include
controls and procedures designed to ensure that information required to be disclosed is accumulated
and communicated to our management, including our CEO and CFO, to allow timely decisions regarding
required disclosures.

Changes in Internal Control over Financial Reporting

There was no change in our internal controls during the fiscal quarter ended January 1, 2022 that

materially affected, or is reasonably likely to materially affect, our internal controls over financial
reporting.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over
financial reporting. Our internal control system was designed to provide reasonable assurance to our
management and Board of Directors regarding the preparation and fair presentation of published financial
statements.

Our management assessed the effectiveness of our internal control over financial reporting as of

January 1, 2022. In making this assessment, it used the criteria set forth by the Committee of Sponsoring
Organizations of the Treadway Commission (COSO) in Internal Control—Integrated Framework (2013
framework). Based on our assessment we concluded that, as of January 1, 2022, our internal control
over financial reporting is effective based on those criteria.

Our independent registered public accounting firm, Ernst & Young LLP, issued an attestation report

on our internal control over financial reporting. This report appears on page F-4.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders of Silicon Laboratories Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Silicon Laboratories Inc.

(the Company) as of January 1, 2022 and January 2, 2021, the related consolidated statements of
income, comprehensive income, changes in stockholders’ equity and cash flows for each of the
three years in the period ended January 1, 2022, 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 at January 1, 2022 and January 2,
2021, and the results of its operations and its cash flows for each of the three years in the period ended
January 1, 2022, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting

Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of
January 1, 2022, based on criteria established in Internal Control-Integrated Framework issued by the
Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report
dated February 2, 2022 expressed an unqualified opinion thereon.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility

is to express an opinion on the Company’s financial statements based on our audits. We are a public
accounting firm registered with the 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 financial
statements are free of material misstatement, whether due to error or fraud. Our audits included
performing procedures to assess the risks of material misstatement of the 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 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 financial statements. We
believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of
the financial statements that were communicated or required to be communicated to the audit committee
and that: (1) relate to accounts or disclosures that are material to the financial statements and
(2) involved 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 matters below, providing separate opinions
on the critical audit matters or on the accounts or disclosures to which they relate.

F-1

Description of the Matter

How We Addressed the
Matter in Our Audit

Description of the Matter

Recognition of Variable Consideration

At January 1, 2022 the Company’s revenue returns liability, which is
included in the deferred revenues and returns liability in the consolidated
balance sheet, was $13.8 million. As discussed in Note 2 of the
consolidated financial statements, when recording revenue for its contracts
with customers the Company estimates variable consideration at the most
likely amount to which it expects to be entitled. Variable consideration that
does not meet revenue recognition criteria is deferred and a revenue
returns liability is recorded. The variable consideration estimate considers
both the likelihood of a return and the amount of potential price
concession.

Auditing management’s estimate of the revenue returns liability was
judgmental because the calculation involves subjective management
assumptions about the estimates of expected future price concessions
and/or product returns. For example, the estimated variable consideration
included in the transaction price reflects management’s evaluation of
contractual terms, historical experience, assumptions about future
economic conditions and the quantity of products distributors are expected
to sell. Changes in those assumptions can have a material effect on the
amount of variable consideration recognized.
We obtained an understanding, evaluated the design and tested the
operating effectiveness of controls over the measurement and valuation of
the variable consideration recognized as revenue and the revenue returns
liability. For example, we tested controls over management’s review of the
variable consideration methodology, the significant assumptions and the
historical data utilized in the estimate for assumed product returns and
expected price concessions.

To test the variable consideration recognized as revenue and the revenue
returns liability, we performed audit procedures that included, among
others, an evaluation of the Company’s methodology and significant
assumptions and estimates, and tested the completeness and accuracy of
the historical data utilized in the estimates. In our assessment of the
methodology, we considered changes in the business, changes to specific
distributor contracts, and evaluated significant assumptions used by
management by comparison to current trends and recent transactions. We
also evaluated the accuracy of management’s assumed product returns
and expected price concessions from prior periods by comparing to
subsequent actual activity.

Accounting for Discontinued Operations

As discussed in Note 3 of the consolidated financial statements, on
July 26, 2021, the Company completed the sale of its Infrastructure and
Automotive (“I&A”) business to Skyworks Solutions, Inc. for $2.75 billion in
cash. In connection with the sale, the Company recognized a pre-tax gain
of $2.4 billion in discontinued operations. As a result of the discontinued
operations classification, the comparative period consolidated financial
statements for fiscal years 2020 and 2019 have been recast to reclassify
balance sheet, income statement and cash flow amounts related to the
infrastructure and automotive business as discontinued operations.

Auditing the Company’s discontinued operations was complex due to
judgments made by management to calculate the gain on sale, including
allocating goodwill between the I&A and Internet of Things (IoT) business
lines as well as the non-routine process used by management to compile

F-2

How We Addressed the
Matter in Our Audit

historical financial data for the I&A business, which involved certain
judgments in allocating expenses to the discontinued operations.

We obtained an understanding, evaluated the design and tested the
operating effectiveness of controls over the Company’s accounting for the
discontinued operations. For example, we tested controls over
management’s treatment of the sale and calculation of the gain on sale,
which included management’s review of the methodologies and
assumptions used in the gain on sale calculation as well as controls over
the disclosure of discontinued operations, including recasting prior period
comparative financial statements.

Our audit procedures included, among others, testing the accuracy of the
gain on sale calculation and evaluating the adequacy of the company’s
disclosures related to discontinued operations. For example, we evaluated
the appropriateness of the company’s application of the criteria for
reporting of discontinued operations by inspecting management’s
supporting documentation, reading of board of director meeting minutes
and other entity information, and evaluating for contrary evidence based
on our understanding of the business. To test the gain recognized in
discontinued operations, we performed audit procedures that included
testing the existence and valuation of cash proceeds; inspecting the
related sale agreement to obtain an understanding of the assets and
liabilities included in the scope of the sales transaction and testing the
completeness and accuracy of the assets and liabilities included in the
gain calculation on a sample basis by comparing amounts to the
Company’s accounting records and testing the tax effects of the sale. To
test the allocation of goodwill between the I&A and IoT business lines, we
involved our valuation specialists to evaluate the reasonableness of the
Company’s valuation methodology and significant assumptions used to
allocate goodwill. For example, we compared the significant assumptions
used by the Company to current market and economic trends, to the
assumptions used to value similar assets in other relevant divestitures,
and to the historical results of the Company. We performed procedures to
audit the presentation of discontinued operations in the financial
statements, including testing the recast prior period financial statements
and assessing the reasonableness of key judgments applied by
management in allocating expenses to the discontinued operations.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders of Silicon Laboratories Inc.

Opinion on Internal Control Over Financial Reporting

We have audited Silicon Laboratories Inc.’s internal control over financial reporting as of January 1,
2022, based on criteria established in Internal Control—Integrated Framework issued by the Committee
of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In
our opinion, Silicon Laboratories Inc. (the Company) maintained, in all material respects, effective internal
control over financial reporting as of January 1, 2022, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting
Oversight Board (United States) (PCAOB), the consolidated balance sheets of Silicon Laboratories
Inc. as of January 1, 2022 and January 2, 2021, the related consolidated statements of income,
comprehensive income, changes in stockholders’ equity and cash flows for each of the three years in the
period ended January 1, 2022, and the related notes and our report dated February 2, 2022 expressed
an unqualified opinion thereon.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial
reporting and for its assessment of the effectiveness of internal control over financial reporting included
in the accompanying Management’s Report on Internal Control over Financial Reporting. Our
responsibility is to express an opinion on the Company’s internal control over financial reporting based
on our audit. We are a public accounting firm registered with the 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 audit in accordance with the standards of the PCAOB. Those standards require

that we plan and perform the audit to obtain reasonable assurance about whether effective internal
control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing

the risk that a material weakness exists, testing and evaluating the design and operating effectiveness
of internal control based on the assessed risk, and performing such other procedures as we considered
necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable
assurance regarding the reliability of financial reporting and the preparation of financial statements for
external purposes in accordance with generally accepted accounting principles. A company’s internal
control over financial reporting includes those policies and procedures that (1) pertain to the
maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and
dispositions of the assets of the company; (2) provide reasonable assurance that transactions are
recorded as necessary to permit preparation of financial statements in accordance with generally
accepted accounting principles, and that receipts and expenditures of the company are being made only
in accordance with authorizations of management and directors of the company; and (3) provide
reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or
disposition of the company’s assets that could have a material effect on the financial statements.

Because of its 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.

Notes to Consolidated Financial Statements
January 1, 2022

1. Description of Business

Silicon Laboratories Inc. (the “Company”), a Delaware corporation, is a leader in secure, intelligent
wireless technology for a more connected world. Our integrated hardware and software platform, intuitive
development tools, industry leading ecosystem and robust support enable customers in building
advanced industrial, commercial, home and life applications. The Company provides analog-intensive,
mixed-signal solutions for use in a variety of electronic products in a broad range of applications for the
Internet of Things (IoT) including connected home and security, industrial automation and control,
smart metering, smart lighting, commercial building automation, consumer electronics, asset tracking
and medical instrumentation. Within the semiconductor industry, the Company is known as a “fabless”
company meaning that the integrated circuits (ICs) incorporated in its products are manufactured by
third-party foundry semiconductor companies.

On April 22, 2021, the Company entered into an Asset Purchase Agreement pursuant to which

Skyworks Solutions, Inc. agreed to acquire certain assets, rights, and properties, and assume certain
liabilities, comprising the Company’s infrastructure and automotive business for $2.75 billion in cash. The
transaction closed on July 26, 2021. The financial results of the infrastructure and automotive business
have been presented as discontinued operations in the Consolidated Financial Statements because
the sale represented a strategic shift for the Company. Prior period financial statements have been
reclassified to reflect these changes for all periods presented. See Note 3, Discontinued Operations, for
additional information. Unless indicated otherwise, the information in the Notes to the Consolidated
Financial Statements relates to the Company’s continuing operations and does not include the results
of discontinued operations.

2. Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

The Company prepares financial statements on a 52- or 53-week fiscal year that ends on the
Saturday closest to December 31. Fiscal 2021 had 52 weeks. Fiscal 2020 had 53 weeks with the extra
week occurring in the first quarter of the year. Fiscal 2019 had 52 weeks. Fiscal 2021, 2020 and
2019 ended on January 1, 2022, January 2, 2021 and December 28, 2019, respectively. The
accompanying Consolidated Financial Statements include the accounts of the Company and its wholly
owned subsidiaries. All significant intercompany balances and transactions have been eliminated in
consolidation.

Foreign Currency Transactions

The Company’s foreign subsidiaries are considered to be extensions of the U.S. Company. The
functional currency of the foreign subsidiaries is the U.S. dollar. Accordingly, gains and losses resulting
from remeasuring transactions denominated in currencies other than U.S. dollars are included in
interest income and other, net in the Consolidated Statements of Income.

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting
principles (GAAP) requires management to make estimates and assumptions that affect the amounts
reported in the financial statements and accompanying notes. Among the significant estimates affecting
the financial statements are those related to inventories, goodwill, acquired intangible assets, other long-
lived assets, revenue recognition, stock-based compensation and income taxes. Actual results could
differ from those estimates, and such differences could be material to the financial statements.

2. Significant Accounting Policies (Continued)

Fair Value of Financial Instruments

The fair values of the Company’s financial instruments are recorded using a hierarchical disclosure

framework based upon the level of subjectivity of the inputs used in measuring assets and liabilities.
The three levels are described below:

Level 1—Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at
the measurement date.

Level 2—Inputs other than Level 1 that are directly or indirectly observable, such as quoted prices
for similar assets or liabilities and quoted prices in less active markets.

Level 3—Inputs are unobservable for the asset or liability and are developed based on the best
information available in the circumstances, which might include the Company’s own data.

Cash and Cash Equivalents

Cash and cash equivalents consist of cash deposits, certificates of deposit, money market funds

and investments in debt securities with original maturities of ninety days or less when purchased.

Investments

The Company’s investments typically have original maturities greater than ninety days as of the

date of purchase and are classified as either available-for-sale or trading securities. Investments in
available-for-sale securities are reported at fair value, with unrealized gains and losses, net of tax,
recorded as a component of accumulated other comprehensive income (loss) in the Consolidated
Balance Sheet. Investments in trading securities are reported at fair value, with both realized and
unrealized gains and losses recorded in interest income and other, net in the Consolidated Statement
of Income. Investments in which the Company has the ability and intent, if necessary, to liquidate in order
to support its current operations (including those with contractual maturities greater than one year
from the date of purchase) are classified as short-term.

The Company reviews its available-for-sale investments as of the end of each reporting period for

declines in fair value based on the specific identification method. The Company records an allowance
for credit loss when a decline in fair value is due to credit-related factors. The Company considers various
factors in determining whether an investment is impaired, including the severity of the impairment,
changes in underlying credit ratings, forecasted recovery, its intent to sell or the likelihood that it would
be required to sell the investment before its anticipated recovery in market value and the probability that
the scheduled cash payments will continue to be made. When the Company concludes that a credit-
related impairment has occurred, the Company assesses whether it intends to sell the security or if it is
more likely than not that it will be required to sell the security before recovery. If either of these two
conditions is met, the Company recognizes a charge in earnings equal to the entire difference between
the security’s amortized cost basis and its fair value. If the Company does not intend to sell a security
and it is not more likely than not that it will be required to sell the security before recovery, the unrealized
loss is separated into an amount representing the credit loss, which is recognized in earnings, and the
amount related to all other factors, which is recorded in accumulated other comprehensive income (loss).

In addition, the Company has made equity investments in non-publicly traded companies. Equity

investments in which the Company does not have control, but has the ability to exercise significant
influence over operating and financial policies, are accounted for using the equity method. The Company’s
proportionate share of income or loss is recorded in equity-method earning in the Consolidated
Statements of Income. The Company has elected to use the measurement alternative under ASU
2019-04 to value non-marketable equity investments that do not have readily determinable fair values.

F-11

Silicon Laboratories Inc.
Notes to Consolidated Financial Statements (Continued)
January 1, 2022

2. Significant Accounting Policies (Continued)

Under the alternative, these non-marketable equity investments are recorded at cost minus impairment,
if any, plus or minus changes resulting from qualifying observable price changes of the same or
similar securities in observable transactions. The Company periodically reviews its equity investments
for declines in fair value based on the specific identification method and writes down investments to their
estimated fair values when it determines that a decline has occurred.

Derivative Financial Instruments

The Company uses derivative financial instruments to manage certain exposures to the variability

of foreign currency exchange rates. The Company’s objective is to offset increases and decreases in
expenses resulting from these exposures with gains and losses on the derivative contracts, thereby
reducing volatility of earnings. The Company does not use derivative contracts for speculative or trading
purposes. The Company recognizes derivatives, on a gross basis, in the Consolidated Balance Sheet
at fair value. Cash flows from derivatives are classified according to the nature of the cash receipt or
payment in the Consolidated Statement of Cash Flows.

The Company also uses foreign currency forward contracts to reduce the earnings impact that

exchange rate fluctuations have on non-U.S. dollar balance sheet exposures. The Company does not
apply hedge accounting to these foreign currency forward contracts.

Inventories

Inventories are stated at the lower of cost, determined using the first-in, first-out method, or net

realizable value. The Company writes down the carrying value of inventory to net realizable value for
estimated obsolescence or unmarketable inventory based upon assumptions about the age of inventory,
future demand and market conditions. Inventory impairment charges establish a new cost basis for
inventory and charges are not subsequently reversed to income even if circumstances later suggest
that increased carrying amounts are recoverable.

Property and Equipment

Property and equipment are stated at cost, net of accumulated depreciation. Depreciation is
computed using the straight-line method over the useful lives of the assets ranging from three to
fifteen years. Leasehold improvements are depreciated over the lease term or their useful life, whichever
is shorter.

The Company owns the facilities for its headquarters in Austin, Texas. The buildings are located
on land which is leased through 2099 from a third party. The rents for these ground leases were prepaid
for the term of the leases. The buildings and leasehold interest in ground leases are being depreciated
on a straight-line basis over their estimated useful lives of 40 years and 86 years, respectively.

Business Combinations

The Company records business combinations using the acquisition method of accounting and,
accordingly, allocates the fair value of acquisition consideration to the assets acquired and liabilities
assumed based on their fair values at the acquisition date. The excess of the fair value of purchase
consideration over the fair value of the assets acquired and liabilities assumed is recorded as goodwill.
The results of operations of the businesses acquired are included in the Company’s consolidated
results of operations beginning on the date of the acquisition.

Long-Lived Assets

Purchased intangible assets are stated at cost, net of accumulated amortization, and are amortized

using the straight-line method over their estimated useful lives, ranging from two to twelve years. Fair

values are determined primarily using the income approach, in which the Company projects future
expected cash flows and applies an appropriate discount rate.

Long-lived assets “held and used” by the Company are reviewed for impairment whenever events

or changes in circumstances indicate that their net book value may not be recoverable. When such
factors and circumstances exist, the Company compares the projected undiscounted future cash flows
associated with the related asset or group of assets over their estimated useful lives against their
respective carrying amounts. Impairment, if any, is based on the excess of the carrying amount over
the fair value of those assets and is recorded in the period in which the determination was made.

The Company tests goodwill for impairment annually as of the first day of its fourth fiscal quarter and
in interim periods if events occur that would indicate that the carrying value of goodwill may be impaired.
The Company assesses goodwill for impairment by comparing the fair value of the reporting unit to its
carrying amount. In determining fair value, several valuation methodologies are allowed, although quoted
market prices are the best evidence of fair value. If the fair value of the reporting unit is less than its
carrying amount, an impairment loss is recognized equal to that excess amount.

Leases

At the commencement date of a lease, the Company recognizes a liability to make lease payments
and an asset representing the right to use the underlying asset during the lease term. The lease liability
is measured at the present value of lease payments over the lease term. As its leases typically do not
provide an implicit rate, the Company uses its incremental borrowing rate based on the information
available at the commencement date taking into consideration necessary adjustments for collateral,
depending on the facts and circumstances of the lessee and the leased asset, and term to match the
lease term. The right-of-use (“ROU”) asset is measured at cost, which includes the initial measurement
of the lease liability and initial direct costs incurred by the Company and excludes lease incentives.
Lease liabilities are recorded in other current liabilities and other non-current liabilities. ROU assets are
recorded in other assets, net.

Lease terms may include options to extend or terminate the lease when it is reasonably certain

that the Company will exercise that option. Operating lease costs are recognized on a straight-line
basis over the lease term. Lease agreements that contain both lease and non-lease components are
generally accounted for separately.

Revenue Recognition

Revenue is recognized when control of the promised goods or services is transferred to the

customer, in an amount that reflects the consideration the Company expects to be entitled to in
exchange for those goods or services. Substantially all of the Company’s contracts with customers
contain a single performance obligation, the sale of mixed-signal integrated circuit (IC) products. This
performance obligation is satisfied when control of the product is transferred to the customer, which
typically occurs upon delivery. Unsatisfied performance obligations primarily represent contracts for
products with future delivery dates. The Company has opted to not disclose the amount of unsatisfied
performance obligations as these contracts have original expected durations of less than one year.

The transaction price reflects the Company’s expectations about the consideration it will be

entitled to receive from the customer and may include fixed or variable amounts. Variable consideration
primarily includes sales made to distributors under agreements allowing certain rights of return,
referred to as stock rotation, and credits issued to the distributor due to price protection. The Company
estimates variable consideration at the most likely amount to which it expects to be entitled. The
estimate is based on information available to the Company, including recent sales activity and pricing

data. The Company applies a constraint to its variable consideration estimate which considers both the
likelihood of a return and the amount of a potential price concession. Variable consideration that
does not meet revenue recognition criteria is deferred. The Company records a right of return asset in
prepaid expenses and other current assets for the costs of distributor inventory not meeting revenue
recognition criteria. A corresponding deferred revenue and returns liability amount is recorded for
unrecognized revenue associated with such costs. The Company’s products carry a one-year
replacement warranty. Payments are typically due within 30 days of invoicing and do not include a
significant financing component.

Shipping and Handling

Shipping and handling costs are classified as a component of cost of revenues in the Consolidated

Statements of Income.

Stock-Based Compensation

The Company has stock-based compensation plans, which are more fully described in Note 16,
Stock-Based Compensation. The Company accounts for those plans using a fair-value method and
recognizes the expense in its Consolidated Statement of Income.

Research and Development

Research and development costs are expensed as incurred. Research and development expense
consists primarily of personnel-related expenses, including stock-based compensation, as well as new
product masks, external consulting and services costs, equipment tooling, equipment depreciation,
amortization of intangible assets, and an allocated portion of our occupancy costs. Assets purchased
to support the Company’s ongoing research and development activities are capitalized when related to
products which have achieved technological feasibility or have an alternative future use, and are
amortized over their estimated useful lives.

Advertising

Advertising costs are expensed as incurred. Advertising expenses were not material for any of the

periods presented.

Income Taxes

The Company accounts for income taxes using the liability method whereby deferred tax asset
and liability account balances are determined based on differences between the financial reporting and
the tax bases of assets and liabilities and are measured using the enacted tax laws and related rates
that will be in effect when the differences are expected to reverse. These differences result in deferred tax
assets and liabilities, which are included in the Company’s Consolidated Balance Sheets. The Company
then assesses the likelihood that the deferred tax assets will be realized. A valuation allowance is
established against deferred tax assets to the extent the Company believes that it is more likely than
not that the deferred tax assets will not be realized, taking into consideration the level of historical taxable
income and projections for future taxable income over the periods in which the temporary differences
are deductible.

Uncertain tax positions must meet a more-likely-than-not threshold to be recognized in the
financial statements and the tax benefits recognized are measured based on the largest benefit that
has a greater than 50% likelihood of being realized upon final settlement. See Note 18, Income Taxes,
for additional information.

Recent Accounting Pronouncements

In August 2020, the Financial Accounting Standards Board (FASB) issued Accounting Standards

Update (ASU) No. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and
Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40). This ASU simplifies the
accounting for certain convertible instruments, amends the guidance on derivative scope exceptions for
contracts in an entity’s own equity and requires the use of the if-converted method for calculating
diluted earnings per share. The ASU removes separation models for convertible debt with a cash
conversion feature. Such convertible instruments will be accounted for as a single liability measured at
amortized cost, as long as no other features require bifurcation and recognition as derivatives. This
ASU is effective for fiscal years beginning after December 15, 2021, including interim periods within those
fiscal years. The Company will elect the modified retrospective transition method to account for the
impact of the adoption with a cumulative-effect adjustment to the opening balance of retained earnings
at the date of adoption. The Company expects the primary impacts of this new standard will be to
increase the carrying value of its convertible debt by approximately $78.5 million, with an offsetting
reduction in stockholders’ equity, and reduce its reported interest expense. In addition, should the
Company be required to use the if-converted method for calculating diluted earnings per share, the
number of shares used in such calculation could potentially increase. On January 2, 2022, the Company
irrevocably elected cash settlement for the principal amount of its convertible senior notes. The
Company intends to settle any excess value in shares in the event of a conversion.

3. Discontinued Operations

On April 22, 2021, the Company entered into an Asset Purchase Agreement pursuant to which

Skyworks Solutions, Inc. agreed to acquire certain assets, rights, and properties, and assume certain
liabilities, comprising the Company’s infrastructure and automotive business for $2.75 billion in cash. The
Company believes the sale accelerates its IoT market leadership and growth, making it a pure-play
leader of intelligent, wireless connectivity for the IoT. The transaction closed on July 26, 2021. The
financial results of the infrastructure and automotive business, which are readily distinguishable from
other components of the Company, have been presented as discontinued operations in the Consolidated
Financial Statements because the sale represented a strategic shift for the Company.

The following table presents the financial results of the infrastructure and automotive business (the
“discontinued operations”) in the Company’s Consolidated Statements of Income (In thousands, except
per share data):

Continuing Involvement

In connection with the closing of the sale, the Company entered into certain ancillary agreements

with Skyworks, including a Transition Services Agreement (“TSA”). Through the TSA, the Company has
subleased certain premises to Skyworks and will provide or provides various temporary support
services for three to eighteen months, depending on the service provided. Although the services provided
under the TSA will generate continuing cash flows between the Company and Skyworks for the
duration of the TSA, the amounts are not expected to be material to the ongoing operations of either
entity. In addition, the Company has no contractual ability through the TSA or any other agreement to
significantly influence the operating or financial policies of Skyworks. The TSA fees were approximately
$4.2 million for fiscal 2021.

Diluted shares for fiscal 2021, 2020 and 2019 excluded 1.5 million, 0.6 million and 0.9 million

shares, respectively, due to the Company’s loss from continuing operations for the periods.

The Company intends to settle the principal amount of its convertible senior notes in cash and any

excess value in shares in the event of a conversion. Accordingly, shares issuable upon conversion of
the principal amount using the treasury stock method have been excluded from the calculation of diluted
earnings per share. If the market value of the notes under certain prescribed conditions exceeds the
conversion amount, the excess is included in the denominator for the computation of diluted earnings per
share using the treasury stock method. For fiscal 2021, 2020 and 2019 approximately 1.0 million
shares, 0.2 million shares and 0.4 million shares, respectively, were included in the denominator for the
calculation of diluted earnings per share from net income. See Note 11, Debt, to the Consolidated
Financial Statements for additional information.

Valuation methodology

The Company’s cash equivalents and short-term investments that are classified as Level 2 are
valued using non-binding market consensus prices that are corroborated with observable market data;
quoted market prices for similar instruments in active markets; quoted prices in less active markets;
or pricing models, such as a discounted cash flow model, with all significant inputs derived from or
corroborated with observable market data. Investments classified as Level 3 are valued using a
discounted cash flow model. The assumptions used in preparing the discounted cash flow model
include estimates for interest rates, amount of cash flows, expected holding periods of the securities
and a discount to reflect the Company’s inability to liquidate the securities. The Company’s derivative
instruments are valued using discounted cash flow models. The assumptions used in preparing the
valuation models include foreign exchange rates, forward and spot prices for currencies and market
observable data of similar instruments.

Contractual maturities of investments

The Company’s investments are reported at fair value, with unrealized gains and losses, net of
tax, recorded as a component of accumulated other comprehensive income (loss) in the Consolidated
Balance Sheet. The following summarizes the contractual underlying maturities of the Company’s
available-for-sale investments at January 1, 2022 (in thousands):

5. Fair Value of Financial Instruments (Continued)

The gross unrealized losses as of January 1, 2022 and January 2, 2021 were due primarily to

changes in market interest rates and the illiquidity of the Company’s auction-rate securities. The
Company’s auction-rate securities have been illiquid since 2008 when auctions for the securities failed
because sell orders exceeded buy orders. These securities have a contractual maturity date of 2046. The
Company is unable to predict if these funds will become available before their maturity date.

The Company records an allowance for credit loss when a decline in investment market value is

due to credit-related factors. When evaluating an investment for impairment, the Company reviews
factors such as the severity of the impairment, changes in underlying credit ratings, forecasted recovery,
the Company’s intent to sell or the likelihood that it would be required to sell the investment before its
anticipated recovery in market value and the probability that the scheduled cash payments will continue
to be made. As of January 1, 2022, there were no material declines in the market value of available-for-
sale investments due to credit-related factors.

At January 1, 2022 and January 2, 2021, there were no material unrealized gains associated with

the Company’s available-for-sale investments.

Significant changes in any of the unobservable inputs used in the fair value measurement of
auction rate securities in isolation could result in a significantly lower or higher fair value measurement.
An increase in expected yield would result in a higher fair value measurement, whereas an increase
in expected holding period or estimated discount rate would result in a lower fair value measurement.
Generally, a change in the assumptions used for expected holding period is accompanied by a directionally
similar change in the assumptions used for estimated yield and discount rate.

5. Fair Value of Financial Instruments (Continued)

The Company’s debt is recorded at cost, but is measured at fair value for disclosure purposes.

The fair value of the Company’s convertible senior notes is determined using observable market
prices. The notes are traded in less active markets and are therefore classified as a Level 2 fair value
measurement. As of January 1, 2022 and January 2, 2021, the fair value of the 0.625% convertible
senior notes due in 2025 was $944.3 million and $671.4 million, respectively.

The Company’s other financial instruments, including cash, accounts receivable and accounts

payable, are recorded at amounts that approximate their fair values due to their short maturities.

6. Derivative Financial Instruments

The Company uses derivative financial instruments to manage certain exposures to the variability

of foreign currency exchange rates. The Company’s objective is to offset increases and decreases in
expenses resulting from these exposures with gains and losses on the derivative contracts, thereby
reducing volatility of earnings.

Non-designated Hedges

Foreign Currency Forward Contracts

The Company uses foreign currency forward contracts to reduce the earnings impact that exchange
rate fluctuations have on non-U.S. dollar balance sheet exposures. The Company recognizes gains and
losses on the foreign currency forward contracts in interest income and other, net in the Consolidated
Statement of Income in the same period as the remeasurement loss and gain of the related foreign
currency denominated asset or liability. The Company does not apply hedge accounting to these foreign
currency forward contracts.

As of January 1, 2022, the Company held one foreign currency forward contract denominated in

Singapore Dollars with a notional value of $3.7 million, and two foreign currency forward contracts
denominated in Indian Rupees with an aggregate notional value of $7.4 million and one foreign currency
forward contract denominated in the Hungarian Forint with a notional value of $2.1 million. The fair
value of foreign contracts and contract losses recognized in income were not material for any of the
periods presented.

8. Risks and Uncertainties

Financial Instruments

Financial instruments that potentially subject the Company to significant concentrations of credit

risk consist primarily of cash equivalents, investments, accounts receivable, notes receivable and
derivatives. The Company places its cash equivalents and investments primarily in municipal bonds,
money market funds, corporate bonds, certificates of deposit, U.S. Treasury bills, U.S. government
securities, agency securities, asset-back securities, commercial paper and auction-rate securities.

8. Risks and Uncertainties (Continued)

Concentrations of credit risk with respect to accounts receivable are primarily due to customers with
large outstanding balances. The Company’s customers that accounted for greater than 10% of accounts
receivable consisted of the following distributors:

Arrow Electronics . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

The Company performs periodic credit evaluations of its customers’ financial condition and
generally requires no collateral from its customers. The Company provides an allowance for expected
credit losses based upon the net amount expected to be collected on such receivables. Losses have not
been significant for any of the periods presented.

As a result of its use of derivative instruments, the Company is exposed to the risk that its

counterparties will fail to meet their contractual obligations. To mitigate this counterparty credit risk, the
Company has a policy to enter into contracts with only selected major financial institutions. The
Company periodically reviews and re-assesses the creditworthiness of such counterparties based on a
variety of factors.

Distributor Advances

On sales to distributors, the Company’s payment terms often require the distributor to initially pay

amounts owed to the Company for an amount in excess of their ultimate cost. The Company’s sales
price to its distributors may be higher than the amount that the distributors will ultimately owe the
Company because distributors often negotiate price reductions after purchasing the product from the
Company and such reductions are often significant. These negotiated price discounts are not granted
until the distributor sells the product to the end customer, which may occur after the distributor has paid
the original invoice amount to the Company. Payment of invoices prior to receiving an associated
discount can have an adverse impact on the working capital of the Company’s distributors. Accordingly,
the Company has entered into agreements with certain distributors whereby it advances cash to the
distributors to reduce the distributor’s working capital requirements. The advance amounts are based on
the distributor’s inventory balance, and are adjusted quarterly. Such amounts are recorded in prepaid
expenses and other current assets in the Consolidated Balance Sheet. The terms of these advances are
set forth in binding legal agreements and are unsecured, bear no interest on unsettled balances and
are due upon demand. The agreements governing these advances can be cancelled by the Company
at any time.

Suppliers

A significant portion of the Company’s products are fabricated by Taiwan Semiconductor
Manufacturing Co. (TSMC) or Semiconductor Manufacturing International Corporation (SMIC). The
inability of TSMC or SMIC to deliver wafers to the Company on a timely basis could impact the production
of the Company’s products for a substantial period of time, which could have a material adverse
effect on the Company’s business, financial condition, results of operations and cash flows.

Customers

The Company sells directly to end customers, distributors and contract manufacturers. Although

the Company actually sells the products to, and is paid by, distributors and contract manufacturers, the
Company refers to the end customer as its customer. None of the Company’s end customers
accounted for greater than 10% of revenue during fiscal 2021, 2020 or 2019. The Company’s distributors
that accounted for greater than 10% of revenue consisted of the following:

0.625% Convertible Senior Notes

On June 1, 2020, the Company completed a private offering of $535 million principal amount
convertible senior notes (the “2025 Notes”). The 2025 Notes bear interest semi-annually at a rate of
0.625% per year and mature on June 15, 2025.

The 2025 Notes are convertible at a conversion rate of 8.1980 shares of common stock per

$1,000 principal amount of the 2025 Notes, or approximately 4.4 million shares of common stock,
which is equivalent to a conversion price of approximately $121.98 per share. The conversion rate is
subject to adjustment under certain circumstances, such as the repurchases of common stock under a
“modified Dutch Auction” tender offer completed during fiscal 2021. Holders may convert the 2025
Notes under the following circumstances: during any calendar quarter after the calendar quarter ended
on September 30, 2020 if the closing price of the Company’s common stock for at least 20 trading
days in the 30 consecutive trading days ending on the last trading day of the preceding calendar quarter
is greater than or equal to $159.51 per share, representing 130% of the conversion price of the 2025
Notes (“the Sales Price Trigger”); during the five business day period after any ten consecutive trading
day period (the “measurement period”) in which the trading price per $1,000 principal amount of notes for
each trading day of the measurement period was less than 98% of the product of the closing sale
price of our common stock and the conversion rate on each such trading day; if specified distributions
or corporate events occur; if the Notes are called for redemption; or at any time after March 15, 2025. The
Company may redeem all or any portion of the 2025 Notes, at its option, on or after June 20, 2023, if
the last reported sale price of the Company’s common stock has been at least 130% of the conversion
price then in effect for at least 20 trading days during any 30 consecutive trading day period. Upon
conversion, the 2025 Notes may be settled in cash, shares of the Company’s common stock or a
combination of cash and shares, at the Company’s election.

The Sales Price Trigger condition was met on January 1, 2022, and as a result, holders may
convert their 2025 Notes at any time during the quarter ending March 31, 2022. Accordingly, the net
carrying amount of the 2025 Notes was reclassified into current liabilities. On January 2, 2022, the
Company irrevocably elected cash settlement for the principal amount of the 2025 Notes. The Company
intends to settle any excess value in shares in the event of a conversion.

The Company incurred debt issuance costs of approximately $10.4 million, which was allocated to
the liability and equity components in proportion to the allocation of the proceeds. The costs allocated
to the liability component are being amortized as interest expense over the term of the 2025 Notes using
the effective interest method.

1.375% Convertible Senior Notes

On March 6, 2017, the Company completed a private offering of $400 million principal amount
convertible senior notes (the “2022 Notes”). The Notes bore interest semi-annually at a rate of 1.375%
per year and were scheduled to mature on March 1, 2022.

11. Debt (Continued)

On January 6, 2021, the Company issued a notice of redemption for the remaining $140.6 million
principal amount of the 2022 Notes. Prior to the redemption, the Company received conversion notices
representing $130.4 million principal amount of the notes. The Company paid $130.4 million in cash
and issued 528,022 shares of common stock for the conversions. Notes representing $10.2 million
principal amount were redeemed at par, plus accrued interest. All note conversions and redemptions
were completed by March 22, 2021. The Company recognized a loss on debt extinguishment of
$3.4 million during fiscal 2021, which was recorded in interest expense in the Consolidated Statements
of Income.

Convertible Debt, Net

The principal balances of the 2025 Notes and 2022 Notes (together, the “Notes”) were separated

into liability and equity components, and recorded initially at fair value. The excess of the principal
amounts of the liability components over their carrying amounts represent the debt discount, which are
amortized to interest expense over the term of the Notes using the effective interest method. The
carrying amounts of the liability components was estimated by discounting the contractual cash flows
of similar non-convertible debt at an appropriate market rate at the date of issuance.

The carrying amount of the Notes consisted of the following (in thousands):

$ 108,438

The liability components of the Notes are recorded in convertible debt on the Consolidated

Balance Sheet. The equity components of the Notes are recorded in stockholders’ equity. The effective
interest rate for the liability component was 5.336% for the 2025 Notes and 4.75% for the 2022
Notes. As of January 1, 2022, the remaining period over which the debt discount and debt issuance
costs will be amortized was 3.5 years for the 2025 Notes. With the Company’s adoption of ASU 2020-06
in fiscal 2022, the principal balance of the 2025 Notes will no longer be separated between liability
and equity components. This will result in an increase to the carrying value of its convertible debt by
$78.5 million, representing the unamortized debt discount, with an offsetting reduction in stockholders’
equity.

Credit Facility

The Company and certain of its domestic subsidiaries (the “Guarantors”) have a $400 million
revolving credit facility with a maturity date of August 7, 2024. The credit facility includes a $25 million
letter of credit sublimit and a $10 million swingline loan sublimit. The Company also has an option to
increase the size of the borrowing capacity by up to the greater of an aggregate of $250 million and
100% of EBITDA of the last four fiscal quarters, plus an amount that would not cause a secured leverage
ratio (funded debt secured by assets/EBITDA) to exceed 3.25 to 1.00, subject to certain conditions.

The credit facility, other than swingline loans, will bear interest at the Eurodollar rate plus an
applicable margin or, at the option of the Company, a base rate (defined as the highest of the Wells
Fargo prime rate, the Federal Funds rate plus 0.50% and the Eurodollar Base Rate plus 1.00%) plus an
applicable margin. Swingline loans accrue interest at the base rate plus the applicable margin for
base rate loans. The applicable margins for the Eurodollar rate loans range from 1.00% to 1.75% and
for base rate loans range from 0.00% to 0.75%, depending in each case, on the leverage ratio as defined
in the credit facility.

The credit facility contains various conditions, covenants and representations with which the
Company must be in compliance in order to borrow funds and to avoid an event of default, including
financial covenants that the Company must maintain a net leverage ratio (funded indebtedness/EBITDA)
of no more than 4.25 to 1, a secured leverage ratio of no more than 3.50 to 1, and a minimum interest
coverage ratio (EBITDA/interest payments) of no less than 2.50 to 1. As of January 1, 2022, the Company
was in compliance with all covenants of the credit facility. The Company’s obligations under the credit
facility are guaranteed by the Guarantors and are secured by a security interest in substantially all assets
of the Company and the Guarantors. As of January 1, 2022, no amounts were outstanding on the
credit facility.

12. Leases

The Company leases certain facilities under operating lease agreements that expire at various

dates through 2030. Some of these arrangements contain renewal options and require the Company
to pay taxes, insurance and maintenance costs. Lease costs for operating leases were $7.4 million,
$5.6 million and $5.8 million during fiscal 2021, 2020 and 2019, respectively.

The Company is involved in various legal proceedings that have arisen in the normal course of

business. While the ultimate results cannot be predicted with certainty, the Company does not expect
them to have a material adverse effect on its Consolidated Financial Statements.

14. Share Repurchases

The Company repurchased 6.5 million shares, 0.2 million shares and 0.3 million shares of its
common stock for $1.15 billion, $16.3 million and $26.7 million during fiscal 2021, 2020 and 2019,
respectively. Shares repurchased in fiscal 2021 included purchases of 4.0 million shares through a
“modified Dutch Auction” tender offer, 1.7 million shares through an accelerated share repurchase
(“ASR”) agreement and 0.8 million shares through the Company’s existing share repurchase program.
The tender offer commenced on August 3, 2021 and expired on August 30, 2021. Shares repurchased
through the tender offer were priced at $160.00 per share, for an aggregate cost of $640.7 million,
excluding fees and expenses relating to the tender offer. Under the ASR Agreement, the Company will
repurchase an aggregate of $400 million of its common stock. In fiscal 2021, the Company received an
aggregate initial share delivery of approximately 1.7 million shares, with the remaining shares, if any,
expected to be delivered in the first fiscal quarter of 2022. Shares purchased through the tender offer,
ASR agreement and share repurchase program were effectively retired upon repurchase.

15. Revenues

Revenues were generated predominately by sales of the Company’s mixed-signal products.
Revenue is recognized when control of the promised goods or services is transferred to the customer,
which typically occurs upon delivery. The transaction price reflects the Company’s expectations about the
consideration it will be entitled to receive from the customer and may include fixed or variable amounts.
Variable consideration that does not meet revenue recognition criteria is deferred.

A portion of the Company’s sales are made to distributors under agreements allowing certain
rights of return and/or price protection related to the final selling price to the end customers. These

factors impact the timing and uncertainty of revenues and cash flows. The Company recognized
revenue of $12.4 million, $11.5 million and $10.3 million during fiscal 2021, 2020 and 2019, respectively,
from performance obligations that were satisfied in previous reporting periods. The following

16. Stock-Based Compensation

Information in this footnote is inclusive of both continuing and discontinued operations, except as

noted.

In fiscal 2009, the stockholders of the Company approved the 2009 Stock Incentive Plan (the
“2009 Plan”) and the 2009 Employee Stock Purchase Plan (the “2009 Purchase Plan”). In fiscal 2017
and fiscal 2021, the stockholders of the Company approved amendments to both the 2009 Plan and the
2009 Purchase Plan. The purpose of the amendments was to authorize additional shares of common
stock for issuance, to comply with changes in applicable law, to improve the Company’s corporate
governance and to implement other best practices.

2009 Stock Incentive Plan

Under the 2009 Plan, the following may be granted: stock options, stock appreciation rights,
performance shares, performance stock units, restricted stock units (RSUs), restricted stock awards
(RSAs), performance-based awards and other awards (collectively, all such grants are referred to as
“awards”). The fiscal 2017 amendments to the 2009 Plan created a single share pool. All awards now
deduct one share from the 2009 Plan shares available for issuance for each share granted. Awards
granted under the 2009 Plan generally contain vesting provisions ranging from three to four years.
The exercise price of stock options offered under the 2009 Plan may not be less than 100% of the fair
market value of a share of our common stock on the date of grant. To the extent awards granted under
the 2009 Plan terminate, expire or lapse for any reason, or are settled in cash, shares subject to such
awards will again be available for grant.

Stock Grants and Modifications

The Company granted to its employees 0.6 million, 0.7 million and 0.7 million shares of full value

awards and no stock options from the 2009 Plan during fiscal 2021, 2020 and 2019, respectively.

The Company recorded $7.8 million in selling, general and administrative expense during fiscal 2021
in connection with the modification of certain equity awards. The modifications were pursuant to employee
terminations. There were no other significant modifications made to any stock grants during fiscal
2021, 2020 or 2019.

Included in the full value awards granted under the 2009 Plan in fiscal 2021 were 116,809

performance-based stock awards (PSUs). PSUs provide for the rights to acquire a number of shares of
common stock for no cash consideration based upon the achievement of specified revenue objectives
during the year. The requisite service period for these PSUs is approximately three years from the date of
grant. There were no performance stock units (PSUs) granted during fiscal 2020 or 2019.

16. Stock-Based Compensation (Continued)

Included in the full value awards granted under the 2009 Plan in fiscal 2020 and 2019 were a total

of 82,000 and 93,000 market-based stock awards, respectively. The awards, also known as market
stock units (MSUs), provide the rights to acquire a number of shares of common stock for no cash
consideration based upon achievement of specified levels of market conditions. The requisite service
period for these MSUs is also the vesting period, which is generally three years. MSUs granted in 2020
and 2019 measure the relative performance of the total stockholders’ return of the Company against
that of a selected benchmarked group of companies. There were no MSUs granted in fiscal 2021.

2009 Employee Stock Purchase Plan

The rights to purchase common stock granted under the 2009 Purchase Plan are intended to be
treated as either (i) purchase rights granted under an “employee stock purchase plan,” as that term is
defined in Section 423(b) of the Internal Revenue Code (the “423(b) Plan”), or (ii) purchase rights granted
under an employee stock purchase plan that is not subject to the terms and conditions of Section 423(b)
of the Internal Revenue Code (the “Non-423(b) Plan”). The Company will retain the discretion to
grant purchase rights under either the 423(b) Plan or the Non-423(b) Plan. Eligible employees may
purchase a limited number of shares of the Company’s common stock at no less than 85% of the fair
market value of a share of common stock at prescribed purchase intervals during an offering period.
Each offering period will be comprised of a series of one or more successive and/or overlapping
purchase intervals and has a maximum term of 24 months. During fiscal 2021, 2020 and 2019, the
Company issued 146,000, 177,000 and 208,000 shares, respectively, under the 2009 Purchase Plan to
its employees. The weighted-average fair value for purchase rights granted in fiscal 2021 under the
2009 Purchase Plan was $41.59 per share.

Accounting for Stock-Based Compensation

Stock-based compensation costs are based on the fair values on the date of grant for stock
awards and stock options and on the date of enrollment for the employee stock purchase plans. The
fair values of stock awards (such as RSUs, PSUs and RSAs) are estimated based on their intrinsic
values. The fair values of MSUs are estimated using a Monte Carlo simulation. The fair values of stock
options and employee stock purchase plans are estimated using the Black-Scholes option-pricing
model.

The Black-Scholes valuation calculation requires the Company to estimate key assumptions such
as future stock price volatility, expected terms, risk-free rates and dividend yield. Expected stock price
volatility is based upon a combination of both historical volatility and implied volatility derived from traded
options on the Company’s stock in the marketplace. Expected term is derived from an analysis of
historical exercises and remaining contractual life of options. The risk-free rate is based on the U.S.
Treasury yield curve in effect at the time of grant. The Company has never paid cash dividends and does
not currently intend to pay cash dividends, thus it has assumed a 0% dividend yield.

The Monte Carlo simulation used to calculate the fair value of the MSUs simulates the present

value of the potential outcomes of future stock prices of the Company and the Philadelphia
Semiconductor Sector Total Return Index over the requisite service period. The projection of stock
prices are based on the risk-free rate of return, the volatilities of the stock price of the Company and
the Index, and the correlation of the stock price of the Company with the Index.

The Company estimates potential forfeitures of stock grants and adjusts compensation cost
recorded accordingly. The estimate of forfeitures will be adjusted over the requisite service period to
the extent that actual forfeitures differ, or are expected to differ, from such estimates. Changes in estimated
forfeitures are recognized through a cumulative catch-up adjustment in the period of change and will
also impact the amount of stock-based compensation expense to be recognized in future periods.

16. Stock-Based Compensation (Continued)

The fair values of stock options and RSUs are amortized as compensation expense on a straight-
line basis over the vesting period of the grants. The fair values of RSAs are fully expensed in the period
of grant when shares are immediately issued with no vesting restrictions. The fair values of MSUs are
amortized as compensation expense on a straight-line basis over the performance and service periods of
the grants. The fair values of PSUs are amortized as compensation expense on a straight-line basis
over the performance period when the performance is probable of achievement, and over the remaining
service periods thereafter. Compensation expense recognized is shown in the operating activities
section of the Consolidated Statements of Cash Flows.

The fair values estimated from the Black-Scholes option-pricing model for ESPP shares granted

were calculated using the following assumptions:

The effective tax rate for fiscal 2021 decreased from fiscal 2020 primarily due to the adoption of

FASB ASU 2019-12, Simplifying the Accounting for Income Taxes, in 2021 and an increase in the
beginning of year valuation allowance on deferred tax assets for state attribute carryforwards. The
effective tax rate for fiscal 2020 increased from fiscal 2019 primarily due to a fiscal 2019 change in the
Company’s position related to the treatment of stock-based compensation within its intercompany cost-
sharing arrangement offset by the increased impact of fiscal 2020 permanent tax differences.

18. Income Taxes (Continued)

The higher provision for income taxes for fiscal 2021 was primarily due to the adoption of
ASU 2019-12 as of the beginning of fiscal 2021. Under ASU 2019-12, which is being applied
prospectively from the date of adoption, the income tax benefit of a loss from continuing operations
should be reallocated to discontinued operations if the Company would be unable to benefit from the
loss without considering the income from discontinued operations. As such, the income tax benefit from
net operating losses associated with continuing operations for fiscal 2021 was reallocated to
discontinued operations. Prior to ASU 2019-12, if the Company reported a loss from continuing
operations and income from discontinued operations, income from discontinued operations would be
considered in determining the income tax benefit allocated to continuing operations. Additionally, for fiscal
2021 there was an increase in the beginning of year valuation allowance on deferred tax assets for
state attribute carryforwards as a result of changes in state tax estimates, primarily due to the divestiture
of the infrastructure and automotive business.

Tax on the gain from the divestiture of the infrastructure and automotive business of $346.9 million

was recorded in discontinued operations for the current period, as well as additional tax benefits
associated with discontinued operations of $7.2 million for fiscal 2021. As of January 1, 2022, income
taxes payable of $74.9 million recorded in connection with the gain from the divestiture was included in
other current liabilities in the Consolidated Balance Sheet.

The Tax Cuts and Jobs Act was enacted in the U.S. on December 22, 2017 and required companies
to pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously deferred
from U.S income tax under U.S. tax law. The Company elected to pay the transition tax over the eight-
year period provided in the Act. As of January 1, 2022, the unpaid balance of its transition tax obligation
was $21.4 million, which is payable between April 2022 and April 2025. This was recorded as
components of other current liabilities and other non-current liabilities in the Consolidated Balance
Sheet in the amounts of $2.4 million and $19.0 million, respectively.

The Company has made an accounting policy election to treat global intangible low-taxed income

(GILTI) as a period expense when incurred.

As of January 1, 2022, the Company had federal net operating loss and research and development
tax credit carryforwards of approximately $18.4 million and $1.8 million, respectively. These carryforwards
expire in fiscal years 2022 through 2031. Recognition of these loss and credit carryforwards is subject
to an annual limit, which may cause them to expire before they are used.

The Company also had state loss, state tentative minimum tax credit, and state research and

development tax credit carryforwards of approximately $30.6 million, $0.5 million, and $11.9 million,
respectively. Certain of these carryforwards expire in fiscal years 2025 through 2036, and others do not
expire. Recognition of some of these loss and credit carryforwards is subject to an annual limit, which
may cause them to expire before they are used.

A valuation allowance is established against a deferred tax asset when it is more likely than not

that the deferred tax asset will not be realized. The Company maintains a valuation allowance with
respect to certain deferred tax assets relating to state research and development tax credits, state net
operating loss carryforwards and state alternative minimum tax credits. The following table summarizes
the activity related to the valuation allowance for deferred tax assets (in thousands):

At the end of fiscal 2021, undistributed earnings of certain of the Company’s foreign subsidiaries

of approximately $107.8 million are intended to be permanently reinvested outside the U.S. Accordingly,
no provision for foreign withholding tax and state income taxes associated with a distribution of these
earnings has been made. Determination of the amount of the unrecognized deferred tax liability on these
unremitted earnings is not practicable.

$2,276

As of January 1, 2022, January 2, 2021 and December 28, 2019, the Company had gross

unrecognized tax benefits, inclusive of interest, of $3.9 million, $3.0 million and $2.4 million, respectively,
of which $3.9 million, $2.1 million and $1.9 million, respectively, would affect the effective tax rate if
recognized.

The Company recognizes interest and penalties related to unrecognized tax benefits in the

provision (benefit) for income taxes. These amounts were not material for any of the periods presented.

Following the completion of the Norwegian Tax Administration (“NTA”) examination of the

Company’s Norwegian subsidiary for income tax matters relating to fiscal years 2013 - 2016, the
Company received an assessment from the NTA in December 2017 concerning an adjustment to its
2013 taxable income related to the pricing of an intercompany transaction. The Company is currently
appealing the assessment. The adjustment to the pricing of the intercompany transaction results in
approximately 141.3 million Norwegian kroner, or $16.0 million, additional Norwegian income tax. The
Company disagrees with the NTA’s assessment and believes the Company’s position on this matter is
more likely than not to be sustained. The Company plans to exhaust all available administrative remedies,
and if unable to resolve this matter through administrative remedies with the NTA, the Company plans
to pursue judicial remedies.

18. Income Taxes (Continued)

The Company believes that it has accrued adequate reserves related to all matters contained in

tax periods open to examination. Should the Company experience an unfavorable outcome in the NTA
matter, however, such an outcome could have a material impact on its financial statements.

Tax years 2015 through 2021 remain open to examination by the major taxing jurisdictions in
which the Company operates. The Company is not currently under audit in any major taxing jurisdiction.

The Company believes it is reasonably possible that its gross unrecognized tax benefits will
decrease by approximately $0.5 million, inclusive of interest, in the next 12 months due to the lapse of
the statute of limitations.

19. Segment Information

The Company has one operating segment, mixed-signal analog intensive products, consisting of
numerous product areas. The Company’s chief operating decision maker is considered to be its Chief
Executive Officer. The chief operating decision maker allocates resources and assesses performance of
the business and other activities at the operating segment level.

Revenue is attributed to a geographic area based on the shipped-to location. The following
