ITEM 1. BUSINESS

Overview

PART l

We design and manufacture semiconductor products for Telecommunications (“Telecom”), Industrial and Defense (“I&D”) and Data Center industries.
Headquartered  in  Lowell,  Massachusetts,  with  operational  facilities  throughout  North  America,  Europe  and  Asia,  we  design,  develop  and  manufacture
differentiated  semiconductor  products  for  customers  who  demand  high  performance,  quality  and  reliability.  We  have  more  than  70  years  of  application
expertise,  combined  with  expertise  in  analog  and  mixed  signal  circuit  design,  compound  semiconductor  fabrication  (including  gallium  arsenide  (“GaAs”),
indium phosphide (“InP”) and specialized silicon), advanced packaging and back-end assembly and test. We offer a broad portfolio of thousands of standard
and  custom  devices,  which  include  integrated  circuits  (“IC”),  multi-chip  modules  (“MCM”),  diodes,  amplifiers,  switches  and  switch  limiters,  passive  and
active components and complete subsystems, across dozens of product lines serving over 6,000 end customers in three primary markets. Our semiconductor
products  are  electronic  components  that  our  customers  incorporate  into  larger  electronic  systems,  such  as  wireless  communication  systems  including
basestations, high capacity optical networks, data center applications, radar, medical systems and test and measurement applications. Our primary end markets
are:  (1)  Telecom,  which  includes  carrier  infrastructure  such  as  long-haul/metro,  5G  and  Fiber-to-the-X  (“FTTx”)/passive  optical  network  (“PON”),  among
others;  (2)  I&D,  which  includes  military  and  commercial  radar,  radio  frequency  (“RF”)  jammers,  electronic  countermeasures,  communication  data  links,
satellite  communications  and  multi-market  applications,  which  include  industrial,  medical,  test  and  measurement  and  scientific  applications;  and  (3)  Data
Center,  which  includes  intra-Data  Center,  Data  Center  Interconnect  (“DCI”)  applications,  at  100G,  200G,  400G,  800G  and  higher  speeds,  enabled  by  our
broad portfolio of analog ICs and photonic components for high speed optical module customers.

Many of our products have long life cycles ranging from five to ten years, and some of our products have been generating revenue for over 20 years. We
continue to develop new products and technologies to improve our ability to serve our primary markets. Our growth strategy is focused on expanding our
product portfolio, strengthening our customer relationships and capturing more design wins in order to increase our market share. As we grow our portfolio
and technology base, we believe our customers will select more of our components for use in their systems.

Our manufacturing model consists of domestic semiconductor wafer fabrication assembly and test capabilities coupled with domestic and international
external foundry and assembly and test partners. We operate semiconductor fabrication facilities at our Lowell, Massachusetts headquarters and in Ann Arbor,
Michigan.  Our  facilities  are  certified  to  the  International  Organization  for  Standardization  (“ISO”)  9001  international  quality  standard,  the  ISO14001
environmental management standard and the ANSI/ESD S20.20:2014 standard. We manufacture compound semiconductors including GaAs and InP. In the
I&D markets, a domestic fabrication facility may be a requirement to be a strategic supplier, and we believe our status as a “Trusted Foundry” offers us further
competitive differentiation.

We also utilize external semiconductor foundries to access additional process technologies and provide additional capacity. We believe that our ability to

utilize a broad array of internal proprietary process technologies and commercially available foundry

3

technologies allows us to select the most appropriate technology to solve our customers’ needs. We believe that this strategy provides us with dependable
supply, control over quality, reduced capital investment requirements, faster time to market and additional outsourced capacity when needed. In addition, the
experience  base  cultivated  through  the  continued  operation  of  our  internal  fabrication  lines  provides  us  with  the  expertise  to  better  manage  our  external
foundry suppliers.

Research and Development

Our research and development efforts are directed toward the rapid development of new and innovative products, process technologies and packaging
techniques.  The  interaction  of  semiconductor  process  technology,  circuit  design  and  packaging  technology  defines  the  performance  parameters  and  the
customers’ acceptance of our products. We believe some of our core competencies are the ability to model, design, test, integrate, package and manufacture
differentiated solutions for our customers. We leverage these core competencies to solve difficult and complex challenges that our customers face during their
system design phases. We believe our integrated and customized solutions offer customers high performance, quality, reliability and faster time to market.

Circuit  design  and  device  modeling  expertise.  Our  engineers  are  experts  in  the  design  of  analog  and  mixed  signal  circuits  capable  of  reliable,  high-
performance RF, microwave, millimeter wave and optical signal transmission and conditioning. Our staff has decades of experience in solving complex design
challenges in applications involving high frequency, high power and environmentally-rugged operating conditions.

Semiconductor process technology. We leverage our domestic semiconductor wafer fabrication capabilities and our foundry suppliers to offer customers
the right process technology to meet their particular requirements. Depending on the requirements for the application, our semiconductor products may be
designed using an internally developed or externally sourced process technology.

Packaging expertise. Our extensive packaging expertise enables us to model the interaction between the semiconductor and its package. Our engineers
make  adjustments  in  the  design  of  both  the  semiconductor  and  the  package,  to  take  account  of  that  interaction.  We  offer  products  in  a  variety  of  different
package types for specific applications, including plastic over-molded, ceramic and laminate-based packaging.

We  continue  to  invest  in  proprietary  processes  to  enable  us  to  develop  and  manufacture  high-value  solutions.  For  example,  we  have  developed
innovative  technologies  such  as  heterolithic  microwave  integrated  circuit  (“HMIC”),  which  provides  high  integration,  high  power  and  low  loss  switching
capabilities  for  our  primary  markets.  More  recently,  we  developed  an  innovative  semiconductor  process  to  support  the  introduction  of  a  new  high  voltage
capacitor product line, branded as MACOM KV CAPS, which represents the industry’s highest voltage silicon-based capacitors.

Our  engineers’  radar,  optical,  microwave  and  millimeter  wave  system-level  design  expertise  allow  us  to  offer  differentiated  solutions  that  leverage

multiple process technologies and are integrated into a single, higher-level assembly, thereby delivering our customers enhanced functionality.

Our Markets and Products

Our  core  strategy  is  to  develop  and  innovate  high-performance  products  that  address  our  customers’  technical  challenges  in  our  primary  markets:
Telecom, I&D and Data Center. While sales in any or all of our primary markets may slow or decline from period to period, over the long-term we generally
expect  to  benefit  from  growth  in  these  markets.  We  expect  our  revenue  in  the  Telecom  market  to  be  driven,  in  part,  by  5G  deployments,  with  continued
upgrades and expansion of communications equipment, increasing adoption of bandwidth rich services. We expect our revenue in the I&D market to be driven
by the expansion of our product portfolio which services test and measurement, satellite communications, civil and military radar, scientific, medical and other
industrial applications. We expect revenue growth in the Data Center market to be driven by the adoption of cloud-based services and the upgrade of data
center architectures to 100G, 200G, 400G and 800G interconnects, which we expect will drive adoption of higher speed optical and photonic wireless links.

Telecom. Underlying growth in the Telecom market is driven by the ever-growing need for increased bandwidth to support data rich applications and
services  such  as  video  conferencing,  cloud  computing,  video-on-demand  and  social  media.  Growth  in  next-generation  Internet  and  Internet  of  Things
applications drives global demand for communications infrastructure equipment requiring amplifiers, filters, receivers, switches, synthesizers, transformers,
upconverters and other components to expand and upgrade cellular backhaul, cellular infrastructure, wired broadband and fiber optic networks. Semiconductor
products and solutions must continually deliver greater bandwidth and functionality as the demands of our customers and end users increase.

Our expertise in system-level architectures and advanced IC design capability enables us to offer network original equipment manufacturer (“OEM”)
customers highly-integrated solutions optimized for performance and cost. Our portfolio of opto-electronics products includes lasers, clock and data recovery,
optical post amplifiers, laser and modulator drivers, transimpedance amplifiers, transmitter and receiver applications in 2.5/10/40/100/400 gigabits per second
long  haul,  metro,  data  center  links  and  FTTx  fiber  optic  network  components  that  enable  telecommunications  carriers  and  data  centers  to  cost-efficiently
increase their network capacity by a factor of four to ten times over earlier generation solutions. We match our opto-electronic components to various lasers
enabling our customers to buy more complete solutions for their opto-electronic systems. For optical communications applications, we utilize a

4

proprietary  combination  of  GaAs,  InP  and  Silicon  Germanium  (“SiGe”)  technologies  to  obtain  advantages  in  performance  and  size.  For  wired  broadband
applications, we offer OEM customers the opportunity to streamline their supply chain through our broad catalog of active components such as active splitters,
amplifiers, multi-function ICs and switches, as well as passive components such as transformers, diplexers, filters, power dividers and combiners.

Industrial & Defense. In the I&D market, military applications require advanced electronic systems, such as radar warning receivers, communications
data links and tactical radios, unmanned aerial vehicles, RF jammers, electronic countermeasures and smart munitions. Military applications are becoming
more sophisticated and requiring more high speed bandwidth, favoring higher performance semiconductor ICs based on GaAs and Gallium Nitride (“GaN”)
technologies due to their high power density, improved power efficiency and broadband capability.

We believe our analog design capabilities, technology portfolio, in-depth knowledge of critical radar system requirements, integration expertise and track
record of reliability make us a valued resource for our I&D customers faced with demanding application parameters. Further, we have been accredited by the
United  States  Department  of  Defense  with  “Trusted  Foundry”  status,  a  designation  conferred  on  microelectronics  vendors  exhibiting  the  highest  levels  of
process integrity and protection, which we believe differentiates us as a trusted manufacturer of ICs for U.S. military and aerospace applications. For radar
applications, we offer standard and custom amplifiers, discrete components, switch limiters, phase shifters and integrated modules for transmit and receive
functions in air traffic control, marine, weather, and military radar applications. For military communications data link and tactical radio applications, we offer
a  family  of  active,  passive  and  discrete  products,  such  as  Monolithic  Microwave  Integrated  Circuits  (“MMICs”),  control  components,  voltage-controlled
oscillators (“VCOs”), transformers, power pallets, amplifiers and diodes. We believe manufacturing products in our Lowell, Massachusetts Trusted Foundry
offers us a competitive advantage in the I&D market because of certain customers’ requirements for a domestic supply chain.

Growth  in  the  I&D  business  is  also  driven  by  multi-market  applications  encompassing  industrial,  medical,  test  and  measurement  and  scientific
applications, where analog RF, microwave and millimeter wave semiconductor solutions are gaining prevalence. In addition, evolving medical technology has
increased the need for high-performance MMICs and other semiconductor solutions in medical imaging and patient monitoring to provide enhanced analysis
and functionality.

In the medical industry, our custom designed non-magnetic diode product line is a critical component for certain MRI applications. For sensing and test
and measurement applications, we believe our HMIC process is ideal for high-performance, integrated bias networks and switches. Our catalog of general
purpose  GaAs  ICs  includes  low  noise  amplifiers,  switches  and  power  amplifiers  that  address  a  wide  range  of  applications  such  as  industrial  automation
systems to test and measurement equipment.

Data Center. Demand by Cloud Data Center providers for faster data delivery speeds at cost-effective prices is growing rapidly, where higher speeds are
necessary to process the current growth in traffic. To solve these challenges, we leverage our broad optical and photonic portfolio of products to enable our
customers  to  deliver  optical  transceivers  that  meet  the  requirements  of  today’s  Cloud  Data  Center  deployments.  By  building  a  comprehensive  portfolio  of
complementary  products  that  enable  our  customers’  optical  transceiver  applications,  we  can  offer  high  performing,  cost-effective  component  solutions  for
next-generation networks.

We enable the market with a complete product portfolio of PAM-4 PHYs, TIAs, Modulator Drivers, Lasers and Silicon Photonics, and, in some cases,

individual component designs are optimized for use together as a chip-set.

To address our primary markets, we offer a broad range of standard and custom ICs and components. Our product catalog currently consists of thousands
of products including the following key product platforms: amplifiers, ICs, diodes, switches and switch limiters, passive and active components and multi-chip
modules. Many of our product platforms are leveraged across multiple markets and applications. For example, our application expertise with regard to power
amplifier technology is leveraged across both scientific laboratory equipment applications and commercial and defense radar system applications. Our diode
technology is used in switch filter banks of military tactical radios as well as medical imaging MRI systems.

Sales and Marketing

We employ a global multi-channel sales strategy and support model intended to facilitate customers’ evaluations and selections of our products. We sell
through our direct sales force, our application engineering staff, our global network of independent sales representatives, resellers and distributors. We have
strategically  positioned  our  direct  sales  and  applications  engineering  staff  in  locations  worldwide,  augmented  by  independent  sales  representatives  and
distributors with additional domestic and foreign locations to offer responsive local support resources to our customers and to build long-term relationships.
Our application engineers visit customers at their engineering and manufacturing facilities, aid them in understanding our capabilities and collaborate with
them to deliver products that can optimize their system performance. Our global independent sales representatives and distributor network allow us to extend
our sales capabilities to new customers in new geographies more cost effectively than using our direct sales force alone.

Our products are principally sold in North America, Asia and Europe, which is where we concentrate our direct sales force, applications engineering
staff, independent sales representatives and distributors. Sales to our distributors accounted for 35.0%, 45.3% and 33.3% of our revenue in fiscal years 2021,
2020 and 2019, respectively. Our agreements with sales representatives, resellers and distributors may provide for an initial term of one or more years with the
opportunity for subsequent renewals or for an indefinite term, and also typically provide that either party may terminate the agreement for convenience with a
minimum period of prior notice to the other party, usually between 30 and 90 days.

Our  sales  efforts  are  focused  on  the  needs  of  our  customers  in  our  three  primary  markets  rather  than  on  particular  product  lines,  facilitating  product
cross-selling across end markets, and within key accounts. Through our website, customers can inquire about our products, request samples and access our
product selection guides, detailed product brochures and data sheets, application notes, suggested design block diagrams and test fixture information, technical
articles and information regarding quality and reliability.

Customers

Our customer base is diversified and includes OEM customers, contract manufacturers, resellers and distributors. One of our distributors, Richardson
RFPD,  Inc.,  (“Richardson”),  accounted  for  10.7%,  13.5%  and  16.1%  of  our  revenue  in  fiscal  years  2021,  2020  and  2019,  respectively.  Sales  to  two  other
resellers, Gateway Tech Company Limited (“Gateway”) and Pangaea (H.K.) Limited (“Pangaea”), both individually accounted for 11.5% of our revenue in
fiscal year 2020, but did not individually exceed 10% in fiscal years 2021 or 2019. For fiscal years 2021, 2020 and 2019, no direct customer individually
accounted for 10% or more of our revenue and sales to our top 25 direct customers accounted for an aggregate of 43.7%, 40.0% and 47.5% of our revenue,
respectively.

Our orders from and sales to customers in the telecommunications infrastructure and networking markets may tend to be lower in our first fiscal quarter

as compared to other quarters due to seasonal inventory management by large OEM and contract manufacturing customers. 

Competition

The  markets  for  our  products  are  highly  competitive  and  are  characterized  by  continuously  evolving  customer  requirements.  We  believe  that  the

principal competitive factors in our markets include:

▪ the ability of engineering talent to drive innovation and new product development;

6

▪ the ability to timely design and deliver products and solutions that meet or exceed customers’ performance, reliability and price requirements;

▪ the breadth and diversity of product offerings;

▪ the ability to provide a reliable supply of products in sufficient quantities and in a timely manner;

▪ the quality of customer service and technical support; and

▪ the financial reliability, operational stability and reputation of the supplier.

We believe that we compete favorably with respect to these factors. We compete primarily with both our customers’ internal design resources and other
suppliers of high-performance analog semiconductor solutions for use in wireless and wireline RF, microwave, millimeter wave and photonic applications,
some of whom have greater financial resources and scale than us. We expect competition in our markets to change as new competitors enter these markets,
existing competitors merge or form alliances and new technologies emerge. We believe that in the future there will be increased competition from companies
utilizing  alternative  technologies,  including  high-volume  manufacturers  using  low-cost  silicon  process  technology.  Some  of  our  competitors  are  also  our
customers, and in certain product categories we compete with semiconductor manufacturers from which we also obtain foundry services.

In the Telecom and Data Center markets, we compete with NXP Semiconductors N.V. (“NXP”), Marvell Technology Inc. (“Marvell”), Maxlinear Inc.
(“Maxlinear”),  Broadcom  Inc.  (“Broadcom”)  and  Semtech  Corporation  (“Semtech”).  In  the  I&D  market,  we  compete  with  Analog  Devices,  Inc.  (“ADI”),
Wolfspeed, Inc. (“Wolfspeed”), Microchip Technology Incorporated (“Microchip”), Qorvo, Inc. (“Qorvo”) and Skyworks Solutions, Inc. (“Skyworks”).

Backlog and Inventory

Our sales are made primarily on a purchase order basis, rather than pursuant to long-term contracts where the customer commits to buy any minimum
amount of product over an extended period. We also frequently ship products from our inventory shortly after receipt of an order, which we refer to as “turns
business.” Unanticipated fluctuations in turns business may result in material shifts in revenue between fiscal quarters. Due to the foregoing factors, different
ordering patterns of our customers and the wide range of lead times to produce and deliver our products, we believe that backlog as of any particular date may
not be a reliable indicator of our future revenue levels.

Intellectual Property

Our success depends in part upon our ability to protect our intellectual property. To accomplish this, we rely on a combination of intellectual property
rights, including patents, copyrights, trademarks and trade secrets, as well as customary contractual protections with our customers, suppliers, employees and
consultants.

 As of October 1, 2021, we had 607 U.S. and 162 foreign issued patents and 95 U.S. and 150 foreign pending patent applications covering elements of
semiconductor devices, circuit design, manufacturing and wafer fabrication. We do not know whether any of our pending patent applications will result in the
issuance of patents or whether the examination process will require us to narrow our claims. The expiration dates of our patents range from 2021 to 2040. We
do not regard any of the patents scheduled to expire in the next twelve months as material to our overall intellectual property portfolio. Notwithstanding our
active  pursuit  of  patent  protection  when  available,  we  believe  that  our  future  success  will  be  determined  by  the  innovation,  technical  expertise  and
management abilities of our engineers and management more than by patent ownership.

The semiconductor industry is characterized by the existence of a large number of patents, copyrights, trademarks and trade secrets, and by the vigorous
pursuit, protection and enforcement of intellectual property rights. Many of our customer agreements require us to indemnify our customers for third-party
intellectual property infringement claims, which may in the future require that we defend those claims and might require that we pay damages in the case of
adverse  rulings.  Claims  of  this  sort  could  harm  our  relationships  with  our  customers  and  might  deter  future  customers  from  doing  business  with  us.  With
respect  to  any  intellectual  property  rights  claims  against  us  or  our  customers  or  distributors,  we  may  be  required  to  cease  manufacture  of  the  infringing
product,  pay  damages  or  settlement  amounts,  expend  resources  to  develop  non-infringing  technology,  seek  a  license,  which  may  not  be  available  on
commercially reasonable terms or at all, or relinquish patents or other intellectual property rights.

Manufacturing, Sources of Supply and Raw Materials

When  designing  a  product  solution  for  our  customers,  we  may  choose  to  utilize  our  internal  proprietary  process  technologies  or  technologies  from
external fabrication facilities, or a combination of both. We believe our ability to select both internal and external technologies in our product solutions is a
competitive advantage because it helps us to provide a unique and optimized solution for our customers.

Our internal wafer fabrication and the majority of our internal assembly and test operations are conducted at our Lowell, Massachusetts headquarters. We

believe having U.S.-based wafer fabrication is a competitive advantage for us over competitors that

7

do not have this capability, because it enables us to offer proprietary processes, and provides us with greater control over quality, a secure source of supply and
a domestic source for U.S. I&D customers. We also believe that our U.S.-based wafer fabrication facilitates shorter time to market for both new and existing
products,  shorter  production  lead  times  than  if  we  utilized  external  foundries  and  allows  us  to  efficiently  produce  a  wide  range  of  low,  medium  and  high
volume  products.  We  perform  internal  assembly  and  test  functions  at  our  Lowell,  Massachusetts,  Nashua,  New  Hampshire,  Ann  Arbor,  Michigan  and
Hsinchu, Taiwan locations.

We complement our internal manufacturing with outsourced foundry partners and other suppliers. Our operations team has extensive expertise in the
management of outsourced manufacturing service providers and other supply chain participants. We believe our fab-lite model of outsourcing certain of our
manufacturing  activities  rather  than  investing  heavily  in  capital-intensive  production  facilities  provides  us  with  the  flexibility  to  respond  to  new  market
opportunities, simplifies operations, provides access to a wider array of process technologies and additional manufacturing capacity and reduces our capital
requirements.  We  also  use  third-party  contract  manufacturers  for  assembly,  packaging  and  test  functions,  and  in  some  cases  for  fully-outsourced  turnkey
manufacturing of our products.

The principal materials used in the production of our IC products are high purity source materials such as gallium, aluminum, arsenic, nitrite, carbon and
silicon.  We  purchase  from  hundreds  of  suppliers  worldwide,  a  wide  variety  of  semiconductors,  wafers,  packages,  metals,  printed  circuit  boards,
electromechanical components and other materials for use in our operations. These supply relationships are generally conducted on a purchase order basis.
The use of external suppliers involves a number of risks, including the possibility of material disruptions in the supply of key raw materials and components,
and the lack of control over delivery schedules, capacity, quality and costs.

While we attempt to maintain alternative sources for our principal raw materials to reduce the risk of supply interruptions or price increases, some of the
raw materials and components are not readily available from alternate suppliers due to their unique nature, design or the length of time necessary for re-design
or qualification. We routinely utilize single sources of supply for various materials based on availability, performance, efficiency or cost considerations. For
example, wafers procured from merchant foundries for a particular process technology are generally sourced through a single foundry on which we rely for all
of our wafers in that process. Our reliance on external suppliers puts us at risk of supply chain disruption if a supplier does not have sufficient raw material
inventory to meet our manufacturing needs, goes out of business, experiences capacity constraints or temporary facility closures, changes or discontinues the
process in which components or wafers are manufactured or declines to continue supplying us for competitive or other reasons, as discussed in more detail in
“Item  1A  -  Risk  Factors”  herein.  Where  practical,  we  attempt  to  mitigate  these  risks  by  qualifying  multiple  sources  of  supply,  redesigning  products  for
alternative components and purchasing incremental inventory of raw materials and components in order to protect us against supply disruptions.

Quality Assurance

The  goal  of  our  quality  assurance  program  is  for  our  products  to  meet  our  customers’  requirements,  be  delivered  on  time,  and  function  reliably
throughout their useful lives. The ISO provides models for quality assurance for various operational disciplines, such as design, manufacturing, and testing,
which comprise part of our overall quality management system. Our following locations have each received ISO 9001:2015 certifications in one or more of
their  principal  functional  areas:  Lowell,  Massachusetts;  Cork,  Ireland;  Ithaca,  New  York;  Santa  Clara  and  Newport  Beach,  California;  Morrisville,  North
Carolina;  Ann  Arbor,  Michigan;  Nashua,  New  Hampshire;  and  Hsinchu,  Taiwan.  In  addition,  our  Lowell,  Massachusetts  facility  has  received  an  ISO
14001:2015  environmental  management  systems  certification,  and,  in  October  2021,  it  received  an  IATF  16949  Automotive  Quality  Management  System
certification.

The ESD Association provides standards for safe and proper handling of electrostatic discharge (“ESD”) in electronic manufacturing environments. Our
following  locations  have  each  received  ANSI/ESD  S20.20:2014  certification:  Lowell,  Massachusetts;  Ann  Arbor,  Michigan;  Allentown,  Pennsylvania;
Morrisville, North Carolina; and Hsinchu, Taiwan.

Environmental Regulation

Our  operations  involve  the  use  of  hazardous  substances  and  are  regulated  under  federal,  state  and  local  laws  governing  health  and  safety  and  the
environment  in  the  U.S.  and  other  countries.  These  regulations  include  limitations  on  discharge  of  pollutants  into  the  air,  water  and  soil;  remediation
requirements; product chemical content limitations; manufacturing chemical use and handling restrictions; pollution control requirements; waste minimization
considerations; and, requirements regarding the treatment, transport, storage and disposal of hazardous wastes. We are also subject to regulation by the U.S.
Occupational  Safety  and  Health  Administration  and  similar  health  and  safety  laws  in  other  jurisdictions.  While  we  are  committed  to  compliance  with
applicable  regulations,  the  risk  of  environmental  liabilities  can  never  be  completely  eliminated  and  there  can  be  no  assurance  that  the  application  of
environmental and health and safety laws to our business will not require us to incur material future expenditures.

We are also regulated under a number of federal, state and local laws regarding responsible sourcing, recycling, product packaging and product content
requirements  in  the  U.S.  and  other  countries,  including  legislation  enacted  in  the  European  Union  and  other  foreign  jurisdictions  that  have  placed  greater
restrictions on the use of lead, among other chemicals, in electronic products, which

8

affects  materials  composition  and  semiconductor  packaging.  These  laws  are  becoming  more  stringent  and  may  in  the  future  cause  us  to  incur  material
expenditures or otherwise cause financial harm.

Export Regulations

We market and sell our products both inside and outside the U.S. Certain products are subject to the Export Administration Regulations, administered by
the  U.S.  Department  of  Commerce,  Bureau  of  Industry  and  Security  (“BIS”),  which  require  that  we  obtain  an  export  license  before  we  can  export  certain
controlled  products  or  technology  to  specified  countries.  Additionally,  some  of  our  products  are  subject  to  the  International  Traffic  in  Arms  Regulations,
which restrict the export of information and material that may be used for military or intelligence applications by a foreign person. Similar controls exist in
other jurisdictions. Failure to comply with these laws could result in sanctions by the government, including substantial monetary penalties, denial of export
privileges  and  debarment  from  government  contracts.  We  maintain  an  export  compliance  program  staffed  by  dedicated  personnel  under  which  we  screen
export transactions against current lists of restricted exports, destinations and end users with the objective of managing export-related decisions, transactions
and shipping logistics to ensure compliance with these requirements.

Human Capital

Employees. As of October 1, 2021, we employed approximately 1,100 individuals worldwide, including approximately 380 in research and

development. We have employees across 17 countries, with 71% in North America, 20% in Asia Pacific and 9% in Europe. None of our domestic employees
are represented by a collective bargaining agreement; however, as of October 1, 2021, approximately 20 of our employees working in certain European
locations were covered by collective bargaining agreements. We consider our relations with employees to generally be good and we have not experienced a
work stoppage due to labor issues.

Approximately 70% and 30% of our workforce is male and female, respectively. Females represented approximately 10% of our senior management and

approximately 15% of our engineering roles.

Corporate  Culture  and  Employee  Engagement.  We  are  committed  to  fostering  a  corporate  culture  that  encourages  and  seeks  the  betterment  of  the
Company  and  the  communities  in  which  we  conduct  business.  Through  our  charitable  giving  program,  we  donate  up  to  5,000  volunteer  hours  to  the
communities in which we operate, by allowing each employee to volunteer up to eight hours per year during working hours on approved charitable activities.
Additionally,  our  employees  engage  directly  with  the  community,  volunteering  their  time  to  a  number  of  organizations.  We  strive  to  foster  a  sense  of
community  and  well-being  that  encourages  our  employees  to  focus  on  both  their  and  the  Company’s  long-term  success.  We  realize  that  continuous
engagement  with  our  employees  in  a  transparent,  collaborative  manner  that  builds  trust  and  fosters  thoughtful  discussion  is  vital  to  driving  successful
outcomes. Executive management regularly conducts town hall-style meetings with employees to address business operations, strategy, market conditions and
other topics. This format encourages open dialogue and provides employees with an opportunity to ask questions and voice opinions and ideas.

Retention and Development. We  devote  substantial  efforts  to  retaining,  motivating  and  supporting  our  employees,  including  by  providing  tuition  and
professional development reimbursement and opportunities for internal growth and advancement. Performance reviews are conducted at least annually for all
employees, during which employees and managers address goals, development opportunities, strengths and areas for improvement. We have also maintained
an internship program that supports the professional development of interns and serves as a recruitment tool for full-time employees. We monitor voluntary
attrition as an indicator of employee engagement. During fiscal year 2021, our voluntary attrition rate was approximately 9%.

Compensation. Our  compensation  policies  recognize  and  reward  individual  and  collective  contributions  to  our  growth  and  success.  We  offer,  among
other things, competitive and balanced compensation programs commensurate with those of our peers and competitors. This includes, but is not limited to,
well-rounded healthcare, prescription drug and disability insurance benefits for our employees and their families, a 401(k) plan for our U.S.-based employees
and equivalent retirement savings programs for our non-U.S.-based employees with a matching contribution by the Company, an employee stock purchase
plan in certain jurisdictions, corporate bonus and equity incentive programs, competitive paid time-off benefits, a parental leave program following the birth,
adoption or fostering of a child and an employee assistance plan that provides professional support, access to special programs and certain resources to our
employees experiencing personal, work, financial or family-related issues.

Diversity, Equity and Inclusion (DE&I). We  have  a  diverse  employee  base,  serving  a  wide  variety  of  customers  across  multiple  geographies.  We  are

strengthened by the broad diversity of our employees’ perspectives, backgrounds, cultures, lifestyles and experiences.

We continue to create a culture of DE&I in the workplace in order to promote and effect change at the corporate and community levels. We support

establishing a work environment where everyone has equal opportunities to learn and grow. Our DE&I efforts are guided by the following principles:

• Diversity is the representation of different people in an organization.

•

Equity is ensuring that everyone has fair, just and equal opportunities at work.

9

•

•

Inclusion is ensuring that everyone has an equal opportunity to contribute to and influence every part and level of a workplace.

Belonging is ensuring that everyone feels safe and welcome at work.

We  regularly  use  our  employee  newsletter  and  communications  meetings  to  share  information,  opportunities  and  updates  with  our  workforce  on  our
DE&I and other initiatives. We are committed to providing equal opportunity in all aspects of employment and do not tolerate discrimination or harassment of
any kind. We maintain a policy against unlawful discrimination, harassment and retaliation which sets forth our position on the prohibition of all forms of
discrimination and harassment in the workplace.

Safety, Health and Well-being. Providing our employees with a healthy and safe working environment is essential. Our goal is to reduce the potential for
injury or illness by maintaining safe working conditions, such as providing proper tools and training to all employees. Additionally, we offer resources to our
employees to encourage healthy habits, such as health coaches, wellness incentives and a diabetes prevention program.

As  a  global  organization,  we  are  committed  to  following  local  government  guidance  related  to  COVID-19  in  every  jurisdiction  where  we  operate,
including adherence to requirements for temporary site closures. We have focused on and continue to focus on ensuring the health and safety of our global
workforce  during  the  COVID-19  global  pandemic,  including,  among  other  things,  by  facilitating,  and  for  certain  locations,  requiring  certain  employees  to
work from home, directing social distancing and implementing extensive health screening and sanitation policies at our facilities to ensure the safety of all
essential  employees.  As  part  of  our  COVID-19  response  plan,  we  implemented  onsite  health  screening,  Company-funded  COVID-19  testing  and  onsite
COVID-19 vaccination in our Lowell, Massachusetts headquarters. We also supported our workforce with advice and guidance on protecting their own health
and the health of their families. We will continue to prioritize the health and safety of our employees during the remainder of the COVID-19 pandemic and
thereafter.

History and Recent Developments

We were incorporated under the laws of the State of Delaware in March 2009. Our operations are conducted through our various subsidiaries, which are

organized and operated according to the laws of their respective jurisdictions of incorporation.

MACOM  Technology  Solutions  Inc.,  our  primary  operating  subsidiary,  which  provides  high-performance  analog  semiconductor  solutions  for  use  in
wireless  and  wireline  applications  across  the  RF,  microwave,  millimeter  wave  and  lightwave  spectrum,  was  incorporated  under  the  laws  of  the  state  of
Delaware on July 16, 2008. MACOM Technology Solutions Limited, our primary foreign operating subsidiary, was incorporated under the laws of Ireland on
November  18,  2008.  The  heritage  of  some  of  our  business  operations  dates  back  over  70  years  to  the  founding  of  Microwave  Associates,  Inc.  and  the
MACOM brand dates back over 30 years.

We completed several acquisitions and divestitures during fiscal years 2017 and 2018 to attempt to further align our businesses to our primary markets.

Those transactions include:

In January 2017, we acquired Applied Micro Circuits Corporation (“AppliedMicro”), a global provider of silicon solutions for next-generation cloud
infrastructure  and  Cloud  Data  Centers,  as  well  as  connectivity  products  for  edge,  metro  and  long-haul  communications  equipment  (the  “AppliedMicro
Acquisition”) in order to expand our business in enterprise and Cloud Data Center applications.

In October 2017, following the acquisition of AppliedMicro, we divested AppliedMicro's Compute business (the “Compute business”) and received an

equity interest in Ampere Computing Holdings LLC (“Ampere”).

In August 2017, we completed the acquisition of Picometrix LLC in order to further expand our design center capabilities and expand our business in

enterprise and Cloud Data Center applications.

In  May  2018,  we  divested  our  long-range  optical  subassembly  product  line  that  we  had  acquired  through  our  December  2015  acquisition  of  FiBest

Limited (“LR4 business”). The LR4 business did not meet our expectations for profitable growth.

Our  acquisition  strategy  is  intended  to  accelerate  our  growth,  expand  our  technology  portfolio,  grow  our  addressable  market  and  create  stockholder

value.

During the fiscal quarter ended June 28, 2019, we committed to a plan designed to strategically realign, streamline and improve certain of our business
and  operations,  including  reducing  our  workforce  by  approximately  250  employees,  exiting  six  development  facilities  in  France,  Japan,  the  Netherlands,
Florida,  Massachusetts  and  Rhode  Island,  reducing  certain  development  activities  for  one  of  our  product  lines  and  no  longer  investing  in  the  design  and
development  of  optical  modules  and  subsystems  for  Data  Center  applications  (the  “2019  Plan”).  These  restructuring  actions  were  completed  in  fiscal  year
2020.

COVID-19 Impact

COVID-19 has spread throughout areas of the world where we operate and resulted in authorities implementing numerous measures to try to contain the
virus. As a result of these measures and the spread of COVID-19, we have modified our business practices and may further modify our practices as required,
or as we determine appropriate. While these measures, as well as other

10

disruptions, have impacted our operations, the operations of our customers and those of our respective vendors and suppliers, such impacts did not, through
the fiscal year ended October 1, 2021, have a material impact on our consolidated operating results.

Given the significant continued economic uncertainty and volatility created by the pandemic, it is difficult to predict the nature and extent of impacts on
the demand for our products. The continued spread of COVID-19 could cause a further economic slowdown or recession and could result in adverse impacts
to our overall business, such as increased credit and collectability risks, adverse impacts on our supply chain, asset impairments, declines in the value of our
financial  instruments  and  adverse  impacts  on  our  capital  resources.  The  degree  to  which  the  COVID-19  pandemic  impacts  our  future  business,  financial
condition, results of operations, liquidity and cash flows will depend on future developments, which are highly uncertain and cannot be accurately predicted,
including the duration and spread of the outbreak, its severity, any resurgence of COVID-19 cases, including as a result of variant strains of the underlying
virus, actions taken to contain the virus or treat its impact, the availability and efficacy of vaccines against COVID-19, how quickly and to what extent normal
operating conditions can resume, and the economic impact on local, regional, national and international markets.

For additional information on risk factors that could impact our future results, please refer to “Item 1A - Risk Factors” in this Annual Report.

ITEM 1A. RISK FACTORS

Our business involves a high degree of risk. You should carefully consider the following risks and other information in this Annual Report in evaluating the
Company and its common stock. If any of the following risks actually occurs, our business, financial condition or results of operations could suffer. The risks
described below are not the only ones facing us. Additional risks not presently known to us or that we currently consider immaterial may also adversely affect
our Company.

Risks Relating to General Business Conditions

Our revenue growth and gross margin are substantially dependent on our successful development and release of new products.

Maintaining or growing our revenue will depend, among other things, on our ability to timely develop products for existing and new markets that meet
customers’  performance,  reliability  and  price  expectations.  In  addition,  the  average  selling  prices  of  our  products  may  decrease  over  time  and  we  must
introduce new products that can be manufactured at lower costs or that command higher prices based on superior performance to offset this expected price
erosion. If we are not able to introduce, in successive years, products that ship in volume, our revenue will likely not grow and may decline significantly and
rapidly. The development of products is a highly complex process, and we have in the past and may in the future experience delays and failures in completing
the development and introduction of new products. Our successful product development depends on a number of factors, including the accurate prediction of
market requirements, changes in technology and evolving standards; the availability of qualified product designers and process technologies needed to solve
design challenges in a cost-effective, reliable manner; our ability to design products that meet customers’ requirements; our ability to successfully design and
manufacture products at competitive prices and volumes; our customers’ acceptance of our product designs; the acceptance of our customers’ products by the
market  and  the  lifecycle  of  such  products;  the  strength  of  and  ability  to  protect  our  intellectual  property  rights;  our  ability  to  obtain,  on  commercially
reasonable  terms,  licenses  to  necessary  third  party  intellectual  property  rights;  and  our  ability  to  maintain  and  increase  our  level  of  product  content  in  our
customers’ systems.

A new product design effort may last over one year, and requires significant investment in engineering, as well as sales and marketing, which may not be
recouped. Our failure to anticipate or timely develop new or enhanced products or technologies in response to technological shifts could result in decreased
revenue and others obtaining design wins. As a result, our gross margin may decrease, we may not reach our expected level of production orders and we may
lose market share, which could adversely affect our ability to sustain our revenue growth or maintain our current revenue levels.

11

Sources for certain components, materials and services are limited, which could result in interruptions, delays or reductions in product shipments.

Our industry may be affected from time to time by limited supplies of certain key components, materials and services. We have in the past and may in
the future, experience delays or reductions in supply shipments, which could reduce our revenue and profitability. In particular, the COVID-19 pandemic has
caused  shortages  of  certain  semiconductor  components  and  delays  in  shipments.  If  key  components,  materials  or  services  are  unavailable,  our  costs  could
increase and our revenue could decline.

Our manufacturing headquarters, design facilities, assembly and test facilities and supply chain, and those of our contract manufacturers, are subject to
risk  of  catastrophic  loss  due  to  fire,  flood  or  other  natural  or  man-made  disasters.  Any  catastrophic  loss  or  significant  damage  to  any  of  these  facilities,
particularly our Lowell, Massachusetts headquarters, could materially disrupt our operations, delay production, shipments and revenue and result in significant
expenses  to  repair  or  replace  the  facility  and,  in  some  instances,  could  significantly  curtail  our  research  and  development  efforts,  and  adversely  affect  our
business and financial results, revenue and profitability.

We  are  subject  to  supply,  order  and  shipment  uncertainties.  Our  profitability  will  decline  if  we  fail  to  accurately  forecast  customer  demand  when
managing inventory.

We  generally  sell  our  products  on  the  basis  of  purchase  orders  rather  than  long-term  purchase  commitments  from  our  customers.  Our  customers  can
typically cancel purchase orders or defer product shipments for some period without incurring a liability to us. We typically plan production and inventory
levels based on internal forecasts of customer demand, which can be highly unpredictable and can fluctuate substantially, leading to excess inventory write-
downs and resulting negative impacts on gross margin and net income. We have limited visibility into our customers’ inventories, future customer demand and
the  product  mix  that  our  customers  will  require,  which  could  adversely  affect  our  production  forecasts  and  operating  margins.  The  difficulty  in  predicting
demand may be compounded when we sell to OEM customers indirectly through distributors or contract manufacturers, as our forecasts of demand are then
based on estimates provided by multiple parties. If we overestimate our customers’ requirements, we may have excess inventory, which could lead to obsolete
inventory, write-downs and unexpected costs. Conversely, if we underestimate our customers’ requirements or are not able to secure components, materials
and/or fabrication facility capacity, we may have inadequate inventory, which could lead to foregone revenue opportunities, loss of potential market share and
damage to customer relationships. Furthermore, obtaining additional supply in the face of any component shortages may be costly or impossible, particularly
in the short term, which could prevent us from fulfilling orders in a timely manner or at all. If our own supply chain or others from whom our customers
source  are  unable  to  deliver  required  components  to  our  customers,  then  our  customers  may  delay  or  cancel  their  product  orders  from  us.  Any  significant
future cancellation or deferral of product orders could adversely affect our revenue and margins, increase inventory write-downs due to obsolete inventory or
adversely affect our operating results and stock price.

Underutilization,  price  competition,  acquisitions  and  various  other  factors  may  reduce  our  gross  margin,  which  could  negatively  affect  our  business,
financial condition and results of operations.

If we are unable to utilize our design, fabrication, assembly and test facilities at a high level, the significant fixed costs associated with these facilities
may not be fully absorbed, resulting in higher than average unit costs and lower gross margin. Similarly, when we compete for business on the basis of our
products’ unit price, the average selling price of our products is reduced, negatively affecting our gross margins. Increased sales of lower-margin products,
increases  in  raw  material  costs,  changes  in  manufacturing  yields  and  other  factors  can  reduce  our  gross  margins  from  time  to  time,  which  could  have  an
adverse impact on our business, financial condition and results of operations in the future. As a result of these or other factors, we may be unable to maintain
or increase our gross margin in future periods and our gross margin may fluctuate from period to period.

Our operating results may fluctuate significantly from period to period. We may not meet investors’ quarterly or annual financial expectations and, as a
result, our stock price may decline.

Our quarterly and annual operating results and related expectations may vary significantly in the future based upon a number of factors, many of which
are beyond our control, including: general economic growth or decline in the U.S. or foreign markets; reduction or cancellation of orders by customers; the
amount of new customer orders we book and ship in any particular fiscal quarter; relative linearity of our shipments within any particular fiscal quarter; the
gain  or  loss  of  a  key  customer  or  significant  changes  in  demand  and/or  fluctuations  in  the  markets  we  serve;  fluctuations  in  the  levels  of  component
inventories held by our customers and accurate forecasting by customers; fluctuations in manufacturing output, yields, capacity levels, quality control or other
potential  problems  or  delays  we  or  our  subcontractors  may  experience  in  the  fabrication,  assembly,  testing  or  delivery  of  our  products;  success  of  our
investments in research and development; availability, quality and cost of semiconductor wafers and other raw materials, equipment, components and internal
or  outsourced  manufacturing,  packaging  and  test  capacity,  particularly  where  we  have  only  one  qualified  source  of  supply;  effects  of  seasonal  and  other
changes in customer demand; effects of competitive pricing pressures, including decreases in average selling prices of our products; loss of key personnel or
the shortage of available skilled workers; our failure to remain abreast of new and improved semiconductor process technologies; failure of our partners in
strategic alliances, which may prevent us from achieving commercial success in such alliance; the exposure of our operations to possible capital and exchange
controls, expropriation and other restrictive government actions, changes in intellectual property legal protections and remedies, as well as political unrest,
unstable governments and legal systems and inter-governmental disputes; changes in laws and regulations in

12

the  U.S.  and  other  countries,  or  the  interpretations  thereof;  and  the  effects  of  war,  natural  disasters,  global  pandemics,  acts  of  terrorism,  macroeconomic
uncertainty or decline or geopolitical unrest.

The foregoing factors are difficult to forecast. These and similar factors could materially and adversely affect our quarterly and annual operating results
and related expectations for future periods. If our operating results in any period do not meet our publicly stated guidance or the expectations of investors or
securities analysts, our stock price may decline and has, in the past, declined as a result.

If demand for our products in our primary markets declines or fails to grow, our revenue and profitability may suffer.

Our future growth depends on our ability to anticipate demand and respond to it with products that address our customers' needs. To a significant extent,
this growth depends on the continued growth in usage of advanced electronic systems in our primary markets: Telecom, Data Center and I&D. The rate and
extent to which these markets will grow, if at all, is uncertain. For example, we have focused significant internal resources to meet potential product demand in
the Cloud Data Center Market, but our ability to capitalize on this and other market opportunities in 100G optical networks and GaN technology will depend
on, among other things, the future size and actual growth rates of these markets, the next generation technologies selected by customers, the timing of network
upgrades in these markets and the pace of adoption of our products in these markets. If demand for electronic systems that incorporate our products declines,
fails to grow or grows more slowly than we anticipate, purchases of our products may be reduced, which will adversely affect our business, financial condition
and results of operations.

The effects of the COVID-19 pandemic have materially impacted, and will likely further impact in the future, how we operate our business, and the extent
to which this will impact our business, financial condition and results of operations remains uncertain.

COVID-19, the disease caused by the coronavirus identified in late 2019, has spread throughout areas of the world where we operate and resulted in
authorities  implementing  numerous  measures  to  try  to  contain  the  virus,  such  as  travel  bans  and  restrictions,  quarantines,  stay-at-home  directives  and
lockdowns and business shutdowns. These measures, as well as transportation disruptions, including reduced availability of air transport, port closures and
increased  border  controls,  have  impacted,  and  will  likely  further  impact  in  the  future,  our  operations,  the  operations  of  our  customers  and  those  of  our
respective vendors and suppliers. There is considerable uncertainty regarding the duration and effect of existing measures and potential future measures, and
depending on the magnitude of the disruptions, our business, financial condition and results of operations may be materially and adversely affected.

The ongoing impact of the COVID-19 pandemic is fluid and uncertain, and it could adversely affect our customers’ ability or willingness to purchase our
products, delay prospective customers’ purchasing decisions, negatively impact our supply chain, restrict our ability to provide certain products or delay the
introduction  of  new  product  offerings.  In  addition,  there  are  ongoing  global  impacts  resulting  from  the  pandemic,  including  shortages  of  semiconductor
components and delays in shipments, which has impacted product production and delivery to customers. The spread of COVID-19 has caused us to modify
our business practices, including restricting employee travel, canceling physical participation in meetings, events and conferences, requiring most employees
to work from home and operating with a limited number of employees in certain locations, which could result in production delays and limit our ability to
satisfy orders for certain products. We may take further actions as may be required by government authorities or that we determine are in the best interests of
our employees, customers and suppliers. Moreover, the COVID-19 pandemic or any worsening of the global economic environment as a result thereof may
have the effect of exacerbating other risks described elsewhere in this Part I, “Item 1A - Risk Factors.”

The degree to which the COVID-19 pandemic may impact our business, financial condition, results of operations, liquidity and cash flows will depend
on future developments, which are highly uncertain and cannot be predicted, including the duration and spread of the outbreak, its severity, any resurgence of
COVID-19  cases,  including  as  a  result  of  variant  strains  of  the  underlying  virus,  actions  taken  to  contain  the  virus  or  treat  its  impact,  the  availability  and
efficacy of vaccines against COVID-19 and how quickly and to what extent normal operating conditions can resume. Furthermore, while the potential impacts
of  the  COVID-19  pandemic  may  be  difficult  to  assess  or  predict,  it  has  resulted  in  a  significant  disruption  of  global  financial  markets,  and  any  resulting
recession or long-term market correction could materially impact the value of our common stock, and could result in adverse impacts such as increased credit
and collectibility risks, adverse impacts on our suppliers, asset impairments, declines in the value of our financial instruments and adverse impacts on our
capital  resources.  There  are  no  comparable  recent  events  that  provide  guidance  as  to  the  effect  the  COVID-19  pandemic  may  have,  and,  as  a  result,  the
ultimate impact of the outbreak on our business, financial condition and results of operations is highly uncertain and subject to change.

We depend on orders from a limited number of customers for a significant percentage of our revenue.

In the fiscal year ended October 1, 2021, no direct customer individually accounted for 10% or more of our revenue and sales to our top 10 direct and
distribution customers accounted for an aggregate of 48.9% of our revenue. While the composition of our top 10 customers varies from year to year, we expect
that sales to a limited number of customers will continue to account for a significant percentage of our revenue for the foreseeable future. The purchasing
arrangements with our customers are typically conducted on a purchase order basis that does not require our customers to purchase any minimum amount of
our products over a period of time. As a result, it is possible that any of our major customers could terminate their purchasing arrangements with us with little
or no warning and without penalty, or significantly reduce or delay the amount of our products that they order, purchase products from our

13

competitors or develop their own products internally. The loss of, or a reduction in, orders from any major customer may cause a material decline in revenue
and adversely affect our results of operations.

We may incur significant risk and expense in attempting to win new business and such efforts may never generate revenue.

To obtain new business, we often need to win a competitive selection process to develop semiconductors for use in our customers’ systems, known in the
industry as a “design win.” Failure to obtain a design win can result in lost or foregone revenue and could weaken our position in future competitive selection
processes or cause us to fail to meet revenue projections or expectations.

Even when we achieve a design win, success is not guaranteed. Customer qualification and design cycles can be lengthy, and it may take a year or more
following a successful design win and product qualification for one of our products to be purchased in volume by the customer. Furthermore, any difficulties
our customer may experience in completing its own qualifications may delay or prevent us from translating the design win into revenue. Any of these events
or  any  cancellation  of  a  customer’s  program  or  failure  of  our  customer  to  market  its  own  product  successfully  after  our  design  win,  could  materially  and
adversely affect our business, financial condition and results of operations, as we may have incurred significant expense and generated no revenue.

We operate in the semiconductor industry, which is cyclical and subject to significant downturns.

The  semiconductor  industry  is  highly  cyclical  and  is  characterized  by  constant  and  rapid  technological  change,  price  erosion,  product  obsolescence,
evolving  standards,  short  product  lifecycles  and  significant  fluctuations  in  supply  and  demand.  The  industry  has  historically  experienced  significant
fluctuations in demand and product obsolescence, resulting in product overcapacity, high inventory levels and accelerated erosion of average selling prices.
Downturns  in  this  industry  may  be  prolonged,  and  downturns  in  many  sectors  of  the  electronic  systems  industry  have  in  the  past  contributed  to  extended
periods  of  weak  demand  for  semiconductor  products.  We  have  experienced  decreases  in  our  revenue,  profitability,  cash  flows  and  stock  price  during  such
downturns in the past, and may be similarly harmed by future downturns, particularly if we are unable to effectively respond to reduced demand in a particular
market.

Our business may be adversely affected if we experience product returns, product liability and defects claims.

Our products are complex and frequently operate in high-performance, challenging environments. We may not be able to anticipate all of the possible
performance or reliability problems that could arise with our products after they are released to the market. If such problems occur or become significant, we
may experience reduced revenue and increased costs related to product recalls, inventory write-offs, warranty or damage claims, delays in, cancellations of or
returns of product orders and other expenses. Certain of our distributors have inventory return and or rotation rights, which may result in higher than expected
product returns. The many materials and vendors used in the manufacture of our products increase the risk that some defects may escape detection in our
manufacturing process and subsequently affect our customers, even in the case of long-standing product designs. Our use of newly-developed or less mature
semiconductor process technologies, such as GaN and InP, which have a less extensive track record of reliability in the field than other more mature process
technologies, also increases the risk of performance and reliability problems. These matters have arisen in our operations from time to time in the past, have
resulted in significant expense to us per occurrence and will likely occur again in the future. The occurrence of defects could result in product returns and
liability claims, reduced product shipments, damage to our customer or supplier relationships, the loss of or delay in market acceptance of our products, costly
litigation, harm to our reputation, diversion of management’s time and resources, lower revenue, increased expenses and reduced profitability. Any warranty
or other rights we may have against our suppliers for quality issues caused by them may be more limited than those our customers have against us, based on
our  relative  size,  bargaining  power  or  otherwise.  In  addition,  any  product  recall  or  product  liability  claim  brought  against  us,  particularly  in  high-volume
consumer markets, could have a material negative impact on our reputation, business, financial condition or results of operations.

Our business and operations could suffer in the event of a security breach, cybersecurity incident or disruption of our information technology systems.

We rely on our information technology systems for the effective operation of our business and for the secure maintenance and storage of confidential
data relating to our business. Although our internal information technology team actively takes steps to protect our information security systems, experienced
programmers or hackers may be able to penetrate our security controls, and develop and deploy viruses, worms and other malicious software programs that
compromise our confidential information or that of third parties and cause a disruption or failure of our information technology systems. In addition, we have
in  the  past  and  may  in  the  future  be  subject  to  “phishing”  attacks  in  which  third  parties  send  emails  purporting  to  be  from  reputable  companies  to  obtain
personal information and infiltrate our systems to initiate wire transfers or otherwise obtain proprietary or confidential information. A number of large, public
companies  have  recently  experienced  losses  based  on  ransomware  and/or  phishing  attacks  and  other  cyber-attacks.  Any  compromise  of  our  information
technology  systems  could  result  in  unauthorized  publication  of  our  confidential  business  or  proprietary  information,  result  in  the  unauthorized  release  of
customer, supplier or employee data, result in violations of privacy or other laws, expose us to a risk of litigation, cause us to incur direct losses if attackers
access our bank or investment accounts, or damage our reputation. The cost and operational consequences of implementing data protection measures either as
a response to specific breaches or as a result of evolving risks could be significant. In addition, our inability to use or access our information systems at critical
points in time could adversely affect the timely and efficient operation of our business. Any delayed sales, significant costs or lost customers resulting from a
technology failure could adversely affect our business, operations and financial results.

14

Third parties with which we conduct business, such as foundries, assembly and test contractors, and distributors, 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
business, operations and financial results.

The outcome of any litigation in which we are involved in is unpredictable and an adverse decision in any such matter could subject us to damage awards
and lower the market price of our stock.

From  time  to  time  we  may  be  a  party  to  certain  litigation  matters.  Any  such  disputes,  litigations,  investigations,  administrative  proceedings  or
enforcement actions may divert financial and management resources that would otherwise be used to benefit our operations, result in negative publicity and
harm our customer or supplier relationships. An adverse resolution of any such matter in the future, including the results of any amicable settlement, could
subject  us  to  material  damage  awards  or  settlement  payments,  loss  of  contractual  or  other  rights,  injunctions  or  other  limitations  on  the  operation  of  our
business or other material harm to our business.

Our term loan and revolving credit facility could result in outstanding debt with a claim to our assets that is senior to that of our stockholders and may
have other adverse effects on our results of operations.

As of October 1, 2021, we had a credit facility consisting of a term loan facility with an outstanding principle balance of $120.8 million and a revolving
credit  facility  with  $160.0  million  of  available  borrowing  capacity.  The  facility  is  secured  by  a  first  priority  lien  on  our  assets  and  those  of  our  domestic
subsidiaries.  The  amount  of  our  indebtedness  could  have  important  consequences,  including  that  we  may  be  unable  or  limited  in  our  ability  to  obtain
additional financing on favorable terms in the future for working capital, capital expenditures, acquisitions, general corporate or other purposes; we may be
limited in our ability to make distributions to our stockholders in a sale or liquidation until our debt is repaid in full; we may be more vulnerable to economic
downturns, less able to withstand competitive pressures and less flexible in responding to changing business and economic conditions; and we cannot assure
you that our business will generate sufficient cash flow from operations or other sources to enable us to meet our payment obligations under the facility and to
fund other liquidity needs.

Our credit facility also contains certain restrictive covenants that may limit or eliminate our ability to, among other things, incur additional debt, sell,
lease or transfer our assets, pay dividends, make investments and loans, make acquisitions, guarantee debt or obligations, create liens, enter into transactions
with our affiliates, enter into new lines of business and enter into certain merger, consolidation or other reorganizations transactions, any of which could place
us at a competitive disadvantage relative to our competitors that are not subject to such restrictions. If we are unable to repay the indebtedness, the lenders
could  initiate  a  bankruptcy  proceeding  against  us  or  collection  proceedings  with  respect  to  our  subsidiaries  securing  the  facility,  which  could  materially
decrease the value of our common stock.

We rely on third parties to provide corporate infrastructure services necessary for the operation of our business. Any failure of one or more of our vendors
to provide these services could have a material adverse effect on our business.

We rely on third-party vendors to provide critical corporate infrastructure services, including, among other things, certain services related to information
technology  and  network  development  and  monitoring.  We  depend  on  these  vendors  to  ensure  that  our  corporate  infrastructure  will  consistently  meet  our
business requirements. The ability of these third-party vendors to successfully provide reliable, high quality services is subject to technical and operational
uncertainties that are beyond our control. Any failure of our corporate infrastructure could have a material adverse effect on our business, financial condition
and results of operations.

Variability in self-insurance liability estimates could adversely impact our results of operations.

We self-insure for employee health insurance and workers’ compensation insurance coverage up to a predetermined level, beyond which we maintain
stop-loss insurance from a third-party insurer. Our aggregate exposure varies from year to year based upon the number of participants in our insurance plans.
We  estimate  our  self-insurance  liabilities  using  an  analysis  provided  by  our  claims  administrator  and  our  historical  claims  experience.  Our  accruals  for
insurance  reserves  reflect  these  estimates  and  other  management  judgments,  which  are  subject  to  a  high  degree  of  variability.  If  the  number  or  severity  of
claims for which we self-insure increases, it could cause a material and adverse change to our reserves for self-insurance liabilities, as well as to our earnings.

Risks Relating to International Operations

We are subject to risks from our international sales and operations.

We have operations in Europe and Asia, and customers around the world. As a result, we are subject to regulatory, geopolitical and other risks associated
with  doing  business  outside  of  the  U.S.,  including  currency  controls,  currency  exchange  rate  fluctuations,  new  or  potential  international  trade  agreements,
tariffs,  required  import  and  export  licenses,  and  other  related  international  trade  restrictions  and  regulations.  Further,  there  is  a  risk  that  language  barriers,
cultural differences and other factors associated with our global operations may make them more difficult to manage effectively.

The legal system in many of the regions where we conduct business can lack transparency in certain respects relative to that of the U.S. and can accord
local  government  authorities  a  higher  degree  of  control  and  discretion  over  business  than  is  customary  in  the  U.S.  This  makes  the  process  of  obtaining
necessary  regulatory  approvals  and  maintaining  compliance  inherently  more  difficult  and  unpredictable.  In  addition,  the  protection  accorded  to  proprietary
technology and know-how under certain legal systems may not be as

15

strong as in the U.S., and, as a result, we may lose valuable trade secrets and competitive advantages. The cost of doing business in European jurisdictions can
also be higher than in the U.S. due to exchange rates, local collective bargaining regimes and local legal requirements and norms regarding employee benefits
and employer-employee relations, in particular. We are also subject to U.S. legal requirements related to our foreign operations, including the Foreign Corrupt
Practices Act.

Sales to customers located outside the U.S. accounted for 54.2% of our revenue for the fiscal year ended October 1, 2021. Sales to customers located in
China and the Asia Pacific region typically account for a substantial majority of our overall sales to customers located outside the U.S. We expect that revenue
from  international  sales  generally,  and  sales  to  China  and  the  Asia  Pacific  region  specifically,  will  continue  to  be  a  material  part  of  our  total  revenue.
Therefore,  any  financial  crisis,  trade  war  or  dispute,  domestic  semiconductor  supply  chain  initiatives,  health  crisis  or  other  major  event  causing  business
disruption in international jurisdictions generally, and China and the Asia Pacific region in particular, could negatively affect our future revenues and results of
operations. For example, in May 2019, the BIS added Huawei Technologies Co. Ltd. (“Huawei”) and many of its affiliates to its Entity List (and subsequently
added additional Huawei affiliates), which effectively blocks exports of U.S. products to Huawei and such affiliates. Such actions in the future, as well as
other changes in Chinese laws and regulations, including actions in furtherance of China’s stated policy of reducing its dependence on foreign semiconductor
manufacturers, could increase the cost of doing business in China, foster the emergence of additional Chinese-based competitors and/or decrease the demand
for our products in China, which could have a material adverse effect on our business and results of operations.

Because the majority of our foreign sales are denominated in U.S. dollars, our products become less price-competitive in countries with currencies that
are low or are declining in value against the U.S. dollar. Also, we cannot be sure that our international customers will continue to accept orders denominated in
U.S.  dollars.  If  they  do  not,  our  reported  revenue  and  earnings  will  become  more  directly  subject  to  foreign  exchange  fluctuations.  Some  of  our  customer
purchase orders and agreements are governed by foreign laws, which may differ significantly from U.S. laws. As a result, we may be limited in our ability to
enforce our rights under such agreements and to collect amounts owed to us.

The majority of our assembly, packaging and test vendors are located in Asia. We generally do business with our foreign assemblers in U.S. dollars. Our
manufacturing  costs  could  increase  in  countries  with  currencies  that  are  increasing  in  value  against  the  U.S.  dollar.  Also,  our  international  manufacturing
suppliers  may  not  continue  to  accept  orders  denominated  in  U.S.  dollars.  If  they  do  not,  our  costs  will  become  more  directly  subject  to  foreign  exchange
fluctuations.  From  time  to  time,  we  may  attempt  to  hedge  our  exposure  to  foreign  currency  risk  by  buying  currency  contracts  or  otherwise,  and  any  such
efforts involve expense and associated risk that the currencies involved may not behave as we expect and we may lose money on such hedging strategies or
not properly hedge our risk.

In  addition,  if  terrorist  activity,  armed  conflict,  civil,  economic  or  military  unrest,  natural  disasters,  global  pandemics,  embargoes  or  other  economic
sanctions, enforcement actions against governments, governmental entities or private entities or political instability occurs in the U.S. or other locations, such
events may disrupt our manufacturing, assembly, logistics, security and communications, labor issues and transportation and other disruptions, and could also
result in reduced demand for our products. We have in the past and, may again in the future, experience difficulties relating to employees traveling in and out
of countries facing civil unrest or political instability and with obtaining travel visas for our employees. There can be no assurance that we can mitigate all
identified risks with reasonable effort. The occurrence of any of these events could have a material adverse effect on our operating results.

Risks Relating to Production Operations

Our internal and external manufacturing, assembly and test model subjects us to various manufacturing and supply risks.

We operate a leased semiconductor wafer processing and manufacturing facility at our headquarters in Lowell, Massachusetts, and at our Ann Arbor,
Michigan site. These facilities are also important internal design, assembly and test facilities. We maintain other internal assembly and test operation facilities
as well, including leased sites in Nashua, New Hampshire, and Hsinchu, Taiwan. We also use multiple external foundries for outsourced semiconductor wafer
supply,  as  well  as  multiple  domestic  and  Asian  assembly  and  test  suppliers  to  assemble  and  test  our  products.  A  number  of  factors  will  affect  the  future
success of these internal manufacturing facilities and outsourced supply and service arrangements, including the level of demand for our products; our ability
to expand and contract our facilities and purchase commitments in a timely and cost-effective manner; our ability to generate revenue in amounts that cover
the significant fixed costs of operating our facilities; our ability to qualify our facilities for new products and process technologies in a timely manner and
avoid complications; the availability of raw materials; the availability and continued operation of key equipment; our manufacturing cycle times and yields;
political and economic risks; the occurrence of natural disasters, pandemics, acts of terrorism, armed conflicts or unrest impacting our facilities and those of
our outsourced suppliers; our ability to hire, train, manage and retain qualified production personnel; our compliance with applicable environmental and other
laws and regulations; our ability to avoid prolonged periods of downtime or high levels of scrap in our and our suppliers’ facilities for any reason; and our
ability  to  negotiate  renewals  to  our  existing  lease  agreements  on  favorable  terms  and  without  disruption  to  our  wafer  processing  and  manufacturing  and
internal assembly and test operations at our sites where such activities take place. The effectiveness of our supply chain could be adversely affected by such
issues and harm our results of operations.

16

Minor  deviations  in  the  manufacturing  process  can  cause  substantial  manufacturing  yield  loss  or  even  cause  halts  in  production,  which  could  have  a
material adverse effect on our revenue and gross margin.

Our  products  involve  complexities  in  both  their  design  and  the  semiconductor  process  technology  employed  in  their  fabrication.  In  many  cases,  the
products are also assembled in customized packages or feature high levels of integration. Our products must meet exacting customer specifications for quality,
performance and reliability.

Our  manufacturing  yield,  or  the  percentage  of  units  of  a  given  product  in  a  given  period  that  is  usable  relative  to  all  such  units  produced,  is  a
combination of yields including wafer fabrication, assembly and test yields. Due to the complexity of our products, we periodically experience difficulties in
achieving  acceptable  yields  as  even  minor  deviations  in  the  manufacturing  process  can  cause  substantial  manufacturing  yield  loss  or  halt  production.  Our
customers may also test our components once they have been assembled into their products. The number of usable products that result from our production
process  can  fluctuate  as  a  result  of  many  factors,  including  design  errors;  defects  in  photomasks,  used  to  print  circuits  on  wafers;  minute  impurities  in
materials used; contamination of the manufacturing environment; equipment failure or variations in the manufacturing processes; losses from broken wafers or
other human errors; defects in packaging; and issues and errors in testing. Typically, for a given level of sales, when our yields improve, our gross margin
improves. Conversely, when our yields decrease, our unit costs are typically higher, our gross margin is lower and our profitability is adversely affected, any
or all of which can harm our results of operations and lower our stock price.

Our business may be harmed if systems manufacturers choose not to use components made of the compound semiconductor materials we utilize.

Silicon  semiconductor  technologies  are  the  dominant  process  technologies  for  the  manufacture  of  ICs  in  high-volume,  commercial  markets  and  the
performance of silicon ICs continues to improve. While we use silicon for some applications, we also often use compound semiconductor technologies such as
GaAs, InP, SiGe or GaN to deliver reliable operation at higher power, higher frequency or smaller form factor than a silicon solution has historically allowed.
While  these  compound  semiconductor  materials  offer  high-performance  features,  it  is  generally  more  difficult  to  design  and  manufacture  products  with
reliability and in volume using them. Compound semiconductor technology tends to be more expensive than silicon technology. System designers in some
markets may be reluctant to adopt our non-silicon products or may be likely to adopt silicon products in lieu of our products if silicon products meeting their
demanding  performance  requirements  are  available,  because  of  their  unfamiliarity  with  designing  systems  using  our  products;  concerns  related  to
manufacturing  costs  and  yields;  unfamiliarity  with  our  design  and  manufacturing  processes;  or  uncertainties  about  the  relative  cost  effectiveness  of  our
products.  We  cannot  be  certain  that  additional  systems  manufacturers  will  design  our  compound  semiconductor  products  into  their  systems  or  that  the
companies that have utilized our products will continue to do so in the future. If our products fail to achieve or maintain market acceptance for any of the
above reasons, our results of operations will suffer.

We face risks associated with government contracting.

Some of our revenue is derived from contracts with agencies of the U.S. government or subcontracts with its prime contractors. As a U.S. government
contractor or subcontractor, we may be subject to federal contracting regulations, including the Federal Acquisition Regulations, which govern, among other
things,  the  allowability  of  costs  incurred  by  us  in  the  performance  of  U.S.  government  contracts.  Certain  contract  pricing  is  based  on  estimated  direct  and
indirect costs, which are subject to change. Additionally, the U.S. government is entitled after final payment on certain negotiated contracts to examine all of
our  cost  records  with  respect  to  such  contracts  and  to  seek  a  downward  adjustment  to  the  price  of  the  contract  if  it  determines  that  we  failed  to  furnish
complete, accurate and current cost or pricing data in connection with the negotiation of the price of the contract. In connection with our U.S. government
business,  we  may  also  be  subject  to  government  audits  and  to  review  and  approval  of  our  policies,  procedures  and  internal  controls  for  compliance  with
procurement regulations and applicable laws. In certain circumstances, if we do not comply with the terms of a contract or with regulations or statutes, we
could be subject to downward contract price adjustments or refund obligations or could in extreme circumstances be assessed civil and criminal penalties or be
debarred  or  suspended  from  obtaining  future  contracts  for  a  specified  period  of  time.  Any  such  suspension  or  debarment  or  other  sanction  could  have  an
adverse effect on our business. In addition, if we are unable to comply with security clearance requirements, we might be unable to perform these contracts or
compete for other projects of this nature, which could adversely affect our revenue.

Risks Relating to Research and Development, Intellectual Property and New Technologies

Our investment in technology as well as research and development may not be successful, which may impact our profitability.

The  semiconductor  industry  requires  substantial  investment  in  technology  as  well  as  research  and  development  in  order  to  bring  to  market  new  and
enhanced technologies and products. Our research and development expenses were $138.8 million for the fiscal year ended October 1, 2021. In each of the
last three fiscal years, we invested in research and development as part of our strategy toward the development of innovative products and solutions to help
support  our  growth  and  profitability.  We  cannot  assure  you  if,  or  when,  the  products  and  solutions  where  we  have  focused  our  research  and  development
expenditures  will  become  commercially  successful.  In  addition,  we  may  not  have  sufficient  resources  to  maintain  the  level  of  investment  in  research  and
development required to remain competitive or succeed in our strategy. Our efforts to develop new and improved process technologies for use in our products
require substantial expenditures that may generate an inadequate return on investment, if any, or may take longer than we anticipate to generate a return. For
example, we have in the past and may continue to experience additional and new unexpected

17

difficulties,  expenses  or  delays  in  qualifying  and  completing  certain  of  our  development  projects  including  our  GaN-on-Silicon,  Silicon  Photonics,  certain
Laser  products  and  our  AFRL  related  process  technology  transfer.  These  development  risks  may  be  associated  with  internal  MACOM  capabilities  and/or
external factors, which may include, but not limited to, matters with one or more third party foundries, assembly and test suppliers, qualifying related products
with our customers and marketing efforts, and we may not be successful in process or product qualification and/or manufacturing cost reductions. In addition,
we may not realize the competitive advantage we anticipate from related investments and may not realize customer demand for this technology that meets our
expectations,  any  of  which  could  lead  to  higher  than  expected  operating  expense,  lower  than  expected  revenue  and  gross  margin,  associated  charges  or
otherwise  reduce  the  price  of  our  common  stock.  We  may  not  be  successful  in  our  research  and  development  efforts  or  may  not  realize  the  competitive
advantages, revenues or profits we anticipate from new products, any of which may lead to higher research and development expense, lower than expected
revenues and gross margin and reduced profitability, or may otherwise harm our business or reduce the price of our common stock. Such results, or anticipated
results, may cause us to reevaluate our investment in those areas of our business.

We may incur liabilities for claims of intellectual property infringement relating to our products.

The semiconductor industry is generally subject to frequent litigation regarding patents and other intellectual property rights. In the past we have been,
and  may  in  the  future  be,  subject  to  claims  that  we  have  breached,  infringed  or  misappropriated  patent,  license  or  other  intellectual  property  rights.  Our
customers may assert claims against us for indemnification if they receive claims alleging that their or our products infringe upon others’ intellectual property
rights, and have in the past and may in the future choose not to purchase our products based on their concerns over such a pending claim. In the event of an
adverse result of any intellectual property rights litigation, we could be required to incur significant costs to defend or settle such litigation, pay substantial
damages for infringement, expend significant resources to develop non-infringing technology, incur material liability for royalty payments or fees to obtain
licenses to the technology covered by the litigation or be subjected to an injunction, which could prevent us from selling our products, and materially and
adversely affect our revenue and results of operations. Any claims relating to the infringement of third-party proprietary rights, even if not meritorious, could
result in costly litigation, lost sales or damaged customer relationships and diversion of management’s attention and resources.

Certain of our products currently incorporate technology licensed or acquired from third parties and we expect our products in the future to also require
technology  from  third  parties.  If  the  licenses  to  such  technology  that  we  currently  hold  become  unavailable  or  the  terms  on  which  they  are  available
become commercially unreasonable, or if we are unable to acquire or license necessary technology for our products in the future, our business could be
adversely affected.

We sell products in markets that are characterized by rapid technological changes, evolving industry standards, frequent new product introductions and
increasing  levels  of  integration.  Our  ability  to  keep  pace  with  these  markets  at  times  depends  on  our  ability  to  obtain  technology  from  third  parties  on
commercially reasonable terms to allow our products to remain competitive. If licenses to such technology are not available on commercially reasonable terms
and conditions or at all and we cannot otherwise acquire or integrate such technology, our products or our customers’ products could become unmarketable or
obsolete, we could lose market share and our revenue and results of operations could materially decline. In addition, disputes with third party licensors over
required payments, scope of licensed rights and compliance with contractual terms are common in our industry and we have in the past and may in the future
be subjected to disputes over the terms of such licenses which could result in substantial unanticipated costs or delays in developing substitute technology to
deliver  competitive  products,  damaged  customer  and  vendor  relationships,  indemnification  liabilities  and  declining  revenues  and  profitability.  Such  events
could have an adverse effect on our financial condition and results of operations.

We  depend  on  third  parties  for  products  and  services  required  for  our  business,  which  may  limit  our  ability  to  meet  customer  demand,  assure  product
quality and control costs.

We  purchase  numerous  raw  materials,  such  as  ceramic  packages,  precious  metals,  semiconductor  wafers  and  ICs,  from  a  limited  number  of  external
suppliers. We also currently use several external manufacturing suppliers for assembly and testing of our products, and in some cases for fully-outsourced
turnkey manufacturing of our products. We expect to increase our use of outsourced manufacturing in the future as a strategy. The use of external suppliers
involves  a  number  of  risks,  including  the  possibility  of  material  disruptions  in  the  supply  of  key  components,  the  lack  of  control  over  delivery  schedules,
capacity constraints, manufacturing yields, quality and fabrication costs and misappropriation of our intellectual property. If these vendors’ processes vary in
reliability or quality, they could negatively affect our products and, therefore, our customer relations and results of operations. We generally purchase raw
materials on a purchase order basis and we do not have significant long-term supply commitments from our vendors. The long-term supply commitments we
have may result in an obligation to purchase excess material, which may materially and negatively impact our operating results. In terms of relative bargaining
power, many of our suppliers are larger than we are, with greater resources, and many of their other customers are larger and have greater resources than we
do.  These  vendors  may  choose  to  supply  others  in  preference  to  us  in  times  of  capacity  constraint  or  otherwise,  particularly  where  the  other  customers
purchase in higher volume. Third-party supplier capacity constraints have in the past and may in the future prevent us from supplying customer demand that
we otherwise could have fulfilled at attractive prices. If we have a firm commitment to supply our customers but are unable to do so we may be liable for
resulting damages and expense incurred by our customers.

We utilize sole source suppliers for certain semiconductor packages and other materials and, in some cases, for the particular semiconductor fabrication
process  technologies  manufactured  at  that  supplier’s  facility.  Such  supplier  concentrations  involve  the  risk  of  a  potential  future  business  interruption  if  the
supplier becomes unable or unwilling to supply us at any point. While in some cases alternate suppliers may exist, because there are limited numbers of third-
party wafer suppliers that use the process technologies we select for our products and that have sufficient capacity to meet our needs, it may not be possible or
may  be  expensive  to  find  an  alternative  source  of  supply.  Even  if  we  are  able  to  find  an  alternative  source,  moving  production  to  an  alternative  supplier
requires an extensive qualification or re-qualification process that could prevent or delay product shipments or disrupt customers’ production schedules, which
could harm our business. The loss of a supplier can also significantly harm our business and operating results.

Our limited ability to protect our proprietary information and technology may adversely affect our ability to compete.

Our future success and ability to compete is dependent in part upon our protection of our proprietary information and technology through patent filings,
enforcement of agreements related to intellectual property and otherwise. We cannot be certain that any patents we apply for will be issued or that any claims
allowed from pending applications will be of sufficient scope or strength to provide meaningful protection or commercial advantage. Our competitors may
also be able to design around our patents. Similarly, counterparties to our intellectual property agreements may fail to comply with their obligations under
those agreements, requiring us to resort to expensive and time-consuming litigation in an attempt to protect our rights, which may or may not be successful.
The laws of some countries in which our products are or may be developed, manufactured or sold, may not protect our products or intellectual property rights
to the same extent as U.S. laws. Although we intend to vigorously defend our intellectual property rights, we may not be able to prevent misappropriation of
our technology or may need to expend significant financial and other resources in defending our rights.

In  addition,  we  rely  on  trade  secrets,  technical  know-how  and  other  unpatented  proprietary  information  relating  to  our  product  development  and
manufacturing activities. While we enter into confidentiality agreements with employees and other parties to protect this information, we cannot be sure that
these agreements will be adequate and will not be breached, that we would have adequate remedies for any breach or that our trade secrets and proprietary
know-how will not otherwise become known or independently discovered by others.

Additionally, our competitors may independently develop technologies that are substantially equivalent or superior to our technology. Despite our efforts
to protect our proprietary rights, unauthorized parties may attempt to copy or otherwise obtain or use our products or technology. Patent litigation is expensive
and our ability to enforce our patents and other intellectual property, is limited by our financial resources and is subject to general litigation risks. If we seek to
enforce  our  rights,  we  may  be  subject  to  claims  that  the  intellectual  property  rights  are  invalid,  are  otherwise  not  enforceable  or  are  licensed  to  the  party
against whom we assert a claim. In addition, our assertion of intellectual property rights could result in the other party seeking to assert alleged intellectual
property rights of its own against us, which is a frequent occurrence in such litigations.

Risks Relating to Government Regulations

Changes in U.S. and international laws, accounting standards, export and import controls and trade policies or the enforcement of, or attempt to enforce,
such laws, standards, controls and policies may adversely impact our business and operating results.

Our  future  results  could  be  adversely  affected  by  changes  in  interpretations  of  existing  laws  and  regulations,  or  changes  in  laws  and  regulations,
including, among others, changes in accounting standards, taxation requirements, competition laws, trade laws, import and export restrictions, privacy laws
and environmental laws in the U.S. and other countries. The U.S. government has made statements and taken certain actions that have led to, and may lead to
further, changes to U.S. and international export and import controls or trade policies, including tariffs affecting certain products exported by a number of U.S.
trading partners, including China. In response, many of those trading partners, including China, have imposed or proposed new or higher tariffs on American
products. It is unknown whether and to what extent new tariffs (or other new laws or regulations) will be adopted, or the effect that any such actions would
have on us or our industry and customers. Any unfavorable government policies on international trade, such as export and import controls, capital controls or
tariffs,  may  affect  the  demand  for  our  products  and  services,  increase  the  cost  of  components,  delay  production,  impact  the  competitive  position  of  our
products  or  prevent  us  from  being  able  to  sell  products  in  certain  countries.  If  any  new  export  or  import  controls,  tariffs,  legislation  or  regulations  are
implemented or if existing trade agreements are renegotiated such changes could have an adverse effect on our business, financial condition and results of
operations.  In  addition,  proceedings  to  enforce,  or  the  enforcement  of,  any  laws,  regulations  and  policies  by  the  U.S.  or  other  countries,  and  the  resulting
response to such actions, may have an adverse effect on our business, financial condition and results of operations.

If we fail to comply with export control regulations, we could be subject to substantial fines or other sanctions, including loss of export privileges.

Certain of our products are subject to the Export Administration Regulations, administered by the BIS, which require that we obtain an export license
before we can export products or technology to specified countries. Other products are subject to the International Traffic in Arms Regulations, which restrict
the export of information and material that may be used for military or intelligence applications by a foreign person. U.S. regulators have announced “export
control reform” that has changed and is expected to change many of the rules applicable to us in this area in the future in ways we do not yet fully understand
and we have

19

experienced and will continue to experience challenges in complying with the new rules as they become effective, resulting in difficulties or an inability to
ship products to certain countries and customers.

We are also subject to U.S. import regulations and the import and export regimes of other countries in which we operate. Failure to comply with these
laws could result in sanctions by the U.S. government, including substantial monetary penalties, denial of export privileges and debarment from government
contracts. Any change in export or import regulations or related legislation (or the interpretation thereof), shift in approach by regulators to the enforcement or
scope of existing regulations, specific sanctions by regulators or change in the countries, persons or technologies targeted by such regulations, could harm our
business  by  resulting  in  decreased  use  of  our  products  by,  or  our  decreased  ability  to  export  or  sell  our  products  to,  existing  or  potential  customers  with
international operations. In addition, our sale of our products to or through third-party distributors, resellers and sales representatives creates the risk that any
violation of these laws they may engage in may disrupt our markets or otherwise bring liability on us.

Our financial results may be adversely affected by increased tax rates and exposure to additional tax liabilities.

Our effective tax rate is highly dependent upon the geographic composition of our worldwide earnings and tax regulations governing each region, each
of  which  can  change  from  period  to  period.  We  are  subject  to  income  taxes  in  both  the  U.S.  and  various  foreign  jurisdictions  and  significant  judgment  is
required to determine our worldwide tax liabilities. Our effective tax rate as well as the actual tax ultimately payable could be adversely affected by changes in
the amount of our earnings attributable to countries with differing statutory tax rates, changes in the valuation of our deferred tax assets, changes in tax laws
(or the interpretation of those laws by regulators) or tax rates (particularly in the U.S. or Ireland), increases in non-deductible expenses, the availability of tax
credits, material audit assessments or repatriation of non-U.S. earnings, each of which could materially affect our profitability. For example, as of October 1,
2021, we had $855.8 million of gross federal net operating loss (“NOL”) carryforwards, which, for those generated prior to the effective date of the 2017 Tax
Cuts and Jobs Act (“Tax Act”), will expire at various dates through 2038, while those generated subsequent to the Tax Act have an indefinite carryforward
with no expiration. However, our ability to use these federal NOL carryforwards and other deferred tax assets may be limited and, as a result of our conclusion
that recovery of our U.S. deferred tax assets, including those assumed in the AppliedMicro Acquisition, is not considered more likely than not, we established
a full valuation allowance against our U.S. deferred tax assets as of September 29, 2017. Any significant increase in our effective tax rates could materially
reduce our net income in future periods and decrease the value of your investment in our common stock.

We may need to modify our activities or incur substantial costs to comply with environmental laws, and if we fail to comply with environmental laws, we
could be subject to substantial fines or be required to change our operations.

We are subject to a variety of international, federal, state and local governmental regulations directed at preventing or mitigating climate change and
other environmental harms, as well as to the storage, discharge, handling, generation, disposal and labeling of toxic or other hazardous substances used to
manufacture  our  products  which  could  restrict  our  ability  to  expand  our  facilities  or  build  new  facilities,  or  require  us  to  acquire  additional  expensive
equipment,  modify  our  manufacturing  processes,  or  incur  other  substantial  expenses  which  could  harm  our  business,  financial  condition  and  results  of
operations.  If  we  fail  to  comply  with  these  regulations,  substantial  fines  could  be  imposed  on  us  and  we  could  be  required  to  suspend  production,  alter
manufacturing processes, cease operations or remediate polluted land, air or groundwater, any of which could have a negative effect on our revenue, results of
operations and business. Failure to comply with environmental regulations could subject us to civil or criminal sanctions and property damage or personal
injury claims. We have incurred in the past and may in the future incur environmental liability based on the actions of prior owners, lessees or neighbors of
sites we have leased or may lease in the future, third party commercial waste disposal sites we utilize or sites we become associated with due to acquisitions.

In  addition  to  the  costs  of  complying  with  environmental,  health  and  safety  requirements,  we  may  in  the  future  incur  costs  defending  against
environmental litigation brought by government agencies, lessors at sites we currently lease or have been associated with in the past and other private parties.
A  significant  judgment  or  fine  levied  against  us  or  agreed  settlement  payment  could  materially  harm  our  business,  financial  condition  and  results  of
operations. For example, since 1993, MACOM Connectivity Solutions, LLC (formerly known as AppliedMicro) has been named as a potentially responsible
party  (“PRP”)  along  with  more  than  100  other  companies  that  used  the  Omega  Chemical  Corporation  waste  treatment  facility  in  Whittier,  California  (the
“Omega Site”). The U.S. Environmental Protection Agency has alleged that the Omega Site failed to properly treat and dispose of certain hazardous waste
material. We are a member of a large group of PRPs, known as the Omega Chemical Site PRP Organized Group (“OPOG”), which has agreed to fund certain
ongoing remediation efforts at and nearby the Omega Site and with respect to the regional groundwater allegedly contaminated thereby. Based on currently
available information with respect to the total anticipated level of investigatory, remedial and monitoring costs to be incurred by the OPOG and our allocable
share of those costs, we have a loss accrual for the Omega Site that is not material. However, the proceedings are ongoing and several factors beyond our
control could cause this loss accrual to prove inadequate, and any future increases to our allocation of responsibility among the PRPs or the future reduction of
parties participating in the PRP group could materially increase our potential liability relating to the Omega Site.

20

Environmental regulations such as the WEEE and RoHS directives limit our flexibility and may require us to incur material expense.

Various countries require companies selling a broad range of electrical equipment to conform to regulations such as the Waste Electrical and Electronic
Equipment (“WEEE”) and the European Directive on Restriction of Hazardous Substances (“RoHS”). Environmental standards such as these could require us
to redesign our products in order to comply with the standards, require the development of compliance administration systems or otherwise limit our flexibility
in running our business or require us to incur substantial compliance costs. We have already invested significant resources into complying with these regimes,
and further investments may be required. Alternative designs implemented in response to regulation may be costlier to produce, resulting in an adverse effect
on our gross profit margin. If we cannot develop compliant products in a timely fashion or properly administer our compliance programs, our revenue may
also decline due to lower sales, which would adversely affect our operating results. Further, if we were found to be non-compliant with any rule or regulation,
we could be subject to fines, penalties and/or restrictions imposed by government agencies that could adversely affect our operating results.

Environmental, social and governance responsibility regulations, policies and provisions, as well as customer and investor demands, may make our supply
chain more complex and may adversely affect our relationships with customers and investors.

There is an increasing focus on corporate environmental, social and governance (“ESG”) responsibility in the semiconductor industry, particularly with
OEMs that manufacture consumer electronics. A number of our customers have adopted, or may adopt, procurement policies that include ESG provisions or
requirements that their suppliers should comply with, or they may seek to include such provisions or requirements in their procurement terms and conditions.
An increasing number of investors are also requiring companies to disclose corporate ESG policies, practices and metrics. Legal and regulatory requirements,
as well as investor expectations, on corporate ESG practices and disclosure, are subject to change, can be unpredictable, and may be difficult and expensive
for  us  to  comply  with,  given  the  complexity  of  our  supply  chain  and  manufacturing.  If  we  are  unable  to  comply,  or  are  unable  to  cause  our  suppliers  or
contract  manufacturers  to  comply,  with  such  policies  or  provisions  or  meet  the  requirements  of  our  customers  and  our  investors,  a  customer  may  stop
purchasing products from us or an investor may sell their shares, and may take legal action against us, which could harm our reputation, revenue and results of
operations.

Customer demands and regulations related to “conflict” minerals may force us to incur additional expenses and liabilities.

Pursuant  to  the  Dodd-Frank  Wall  Street  Reform  and  Consumer  Protection  Act,  the  SEC  promulgated  rules  regarding  disclosure  and  reporting
requirements  for  companies  who  use  “conflict”  minerals  mined  from  the  Democratic  Republic  of  Congo  and  adjoining  countries  in  their  products.  In  the
semiconductor industry, these minerals are most commonly found in metals used in the manufacture of semiconductor devices and related assemblies. These
requirements may adversely affect our ability to source related minerals and metals and increase our related cost. We face difficulties and increased expenses
associated  with  complying  with  the  related  disclosure  requirements,  such  as  costs  related  to  determining  the  source  of  any  conflict  minerals  used  in  our
products. Our supply chain is complex and some suppliers may be unwilling to share related confidential information regarding the source of their products or
may  provide  us  information  that  is  inaccurate  or  inadequate.  If  those  risks  arise  or  if  our  processes  in  obtaining  that  information  do  not  fulfill  the  SEC’s
requirements,  we  may  face  both  reputational  challenges  and  SEC  enforcement  risks  based  on  our  inability  to  sufficiently  verify  the  origins  of  the  subject
minerals and metals or otherwise. Moreover, we may encounter challenges to satisfy any related requirements of our customers, which may be different from
or more onerous than the requirements of SEC rules and executive orders. If we cannot satisfy such customers, they may choose a competitor’s products or
disqualify us as a supplier and we may experience lower than expected revenues or have to write off inventory in the event that it becomes unsalable as a
result of these regulations.

Failure to comply with data privacy regimes could subject us to significant expenses, litigation and reputational harm.

In the ordinary course of our business, we have access to sensitive, confidential or personal data or information regarding our employees and others that
is subject to privacy and security laws and regulations. The theft, loss, or misuse of personal data collected, used, stored or transferred by us, or by our third-
party service providers, could result in damage to our reputation, disruption of our business activities, significantly increased business costs or costs related to
defending legal claims or regulatory actions.

Global privacy legislation, enforcement and policy activity are rapidly expanding and creating a complex data privacy compliance environment and the
potential for high-profile negative publicity in the event of any data breach. We are subject to many privacy and data protection laws and regulations in the
United States and around the world, some of which place restrictions on our ability to process personal data across our business. For example, the General
Data Protection Regulation (“GDPR”) became effective in the European Union on May 25, 2018,and requires compliance with rules regarding the handling of
personal data, and California enacted the California Consumer Privacy Act (“CCPA”) as of January 1, 2020, which enhances privacy rights and consumer
protection for residents of California. It is costly to comply with the GDPR, CCPA and other similar laws and regulations. Further, the GDPR provides for
significant penalties in the case of non-compliance of up to €20 million or 4% of worldwide annual revenues, whichever is greater. We have invested, and
continue to invest, human and technology resources into our data privacy compliance efforts. Despite those efforts, there is a risk that we may be subject to
fines and penalties, litigation and reputational harm if we fail to protect the privacy of third party data or to comply with the applicable data privacy regimes.

21

Risks Relating to Business Strategies and Personnel

We face intense competition in our industry, and our inability to compete successfully could negatively affect our operating results.

The  semiconductor  industry  is  highly  competitive.  While  we  compete  with  a  wide  variety  of  companies,  our  significant  competitors  include,  among

others, NXP, Marvell, Maxlinear, Broadcom, Semtech, ADI, Wolfspeed, Microchip, Qorvo and Skyworks.

We believe future competition could also come from companies developing new alternative technologies, component suppliers based in countries with
lower production costs and IC manufacturers achieving higher levels of integration that exceed the functionality offered by our products. Our customers and
suppliers could also develop products that compete with or replace our products. Increased competition has in the past and could in the future lead to lower
prices for our products, reduced demand for our products and a corresponding reduction in our ability to recover development, engineering and manufacturing
costs.

Many of our existing and potential competitors have entrenched market positions, historical affiliations with OEMs, considerable internal manufacturing
capacity,  established  intellectual  property  rights,  strong  brand  recognition  and  substantial  technological  capabilities.  Many  of  them  may  also  have  greater
financial, technical, manufacturing or marketing resources than we do. Consolidation among our competitors could negatively impact our competitive position
and  market  share  and  harm  our  results  of  operations.  In  addition,  certain  countries  such  as  China  have  begun  implementing  initiatives  to  build  domestic
semiconductor supply chains and we may be at a disadvantage in attempting to compete with entities associated with such foreign government efforts. Our
failure to successfully compete could result in lower revenue, decreased profitability and a lower stock price.

We may sell, wind down or exit one or more of our businesses or product lines, from time to time, as a result of our evaluation of our businesses, products
and markets, and any such divestiture could adversely affect our continuing business.

We periodically evaluate our various businesses and product lines and may, as a result, consider the divestiture, wind down or exit of one or more of
those businesses or product lines. Divestitures have inherent risks, including the inability to find potential buyers with favorable terms, the expense of selling
the product line, the possibility that any anticipated sale will be delayed or will not occur and the potential delay or failure to realize the perceived strategic or
financial merits of the divestment.

If we lose key personnel or fail to attract and retain key personnel, we may be unable to pursue business opportunities or develop our products.

We  believe  our  continued  ability  to  recruit,  hire,  retain  and  motivate  highly-skilled  engineering,  operations,  sales,  administrative  and  managerial
personnel is key to our future success. Competition for these employees is intense. Our failure to retain our present employees and hire additional qualified
personnel in a timely manner and on reasonable terms could harm our competitiveness and results of operations. In particular, the loss of any member of our
senior management team could strengthen a competitor, weaken customer relationships or harm our ability to implement our business strategy. In addition,
from time to time, we may recruit and hire employees from our competitors, customers, suppliers and distributors, which could result in liability to us and has
in the past and could in the future, damage our business relationship with these parties.

We depend on third-party sales representatives and distributors for a material portion of our revenues.

We sell many of our products to customers through independent sales representatives and distributors, as well as through our direct sales force. We are
unable  to  predict  the  extent  to  which  our  independent  sales  representatives  and  distributors  will  be  successful  in  marketing  and  selling  our  products.  Our
relationships  with  our  representatives  and  distributors  typically  may  be  terminated  by  either  party  at  any  time,  and  do  not  require  them  to  buy  any  of  our
products.  Sales  to  distributors  accounted  for  approximately  35.0%  of  our  revenue  for  the  fiscal  year  ended  October  1,  2021,  and  sales  to  one  of  our
distributors, Richardson, accounted for 10.7% of our revenue in the same period. If our sales representatives or distributors cease doing business with us or fail
to successfully market and sell our products, our ability to sustain and grow our revenue could be materially adversely affected.

We may make future acquisitions and investments, which involve numerous risks.

We  routinely  evaluate  potential  acquisitions,  investments,  joint  ventures  and  strategic  alliances  involving  complementary  technologies,  design  teams,
products and companies. We may pursue such transactions if appropriate opportunities arise. However, we may not be able to identify suitable transactions in
the future or, if we do, we may face intense competition for such opportunities. In the event we pursue a potential transaction, we will face numerous risks,
including  diverting  management’s  attention  from  normal  daily  operations  of  our  business;  difficulties  in  integrating  the  financial  reporting  capabilities  and
operating systems of any acquired operations to maintain effective internal control over financial reporting and disclosure controls and procedures; potential
loss of key personnel of the acquired company as well as their know-how, relationships and expertise; challenges successfully integrating acquired personnel,
operations and businesses; failing to realize the anticipated synergies and benefits of an acquisition; maintaining favorable business relationships of acquired
operations;  generating  insufficient  revenue  from  completed  transactions  to  offset  expenses  associated  with  our  efforts;  acquiring  material  or  unknown
liabilities  associated  with  any  acquired  operations;  litigation  associated  with  merger  and  acquisition  transactions;  and  increasing  expense  associated  with
amortization or depreciation of intangible and tangible assets we acquire.

22

Past transactions, whether completed or abandoned by us, have resulted, and in the future may result, in significant time and attention, costs, expenses,
liabilities  and  charges  to  earnings.  The  accounting  treatment  for  any  future  transaction  may  result  in  significant  amortizable  intangible  assets  which,  when
amortized, will negatively affect our consolidated results of operations. The accounting treatment may also result in significant goodwill, which, if impaired,
will negatively affect our consolidated results of operations. Furthermore, we may incur debt or issue equity securities to pay for transactions. The incurrence
of  debt  could  limit  our  operating  flexibility  and  be  detrimental  to  our  profitability,  and  the  issuance  of  equity  securities  would  be  dilutive  to  our  existing
stockholders. Any or all of the above factors may differ from the investment community’s expectations in a given quarter, which could negatively affect our
stock price. In the event we make future investments, the investments may decline in value, we may lose all or part of our investment.

We may experience difficulties in managing any future growth.

To successfully conduct business in a rapidly evolving market, we must effectively plan and manage any current and future growth. Our ability to do so
will be dependent on a number of factors, including maintaining access to sufficient manufacturing capacity to meet customer demands; securing sufficient
supply of raw materials and services to avoid shortages or supply bottlenecks; adequately building out our administrative infrastructure to support any current
and future sales growth while maintaining operating efficiencies; adhering to our high quality and process execution standards, particularly as we hire and
train new employees and during periods of high volume; and maintaining high levels of customer satisfaction. If we do not effectively manage any future
growth, we may not be able to take advantage of attractive opportunities in our markets, our operations may be impacted, and we may experience delays in
delivering products to our customers or damaged customer relationships and achieve lower than anticipated revenue and decreased profitability.

We may incur higher than expected expense from or not realize the expected benefits, or any benefits, of consolidation, outsourcing and restructuring
initiatives designed to reduce costs and increase revenue across our operations.

We  have  pursued  in  the  past  and  may  pursue  in  the  future  various  restructuring  initiatives  designed  to  reduce  costs  and  increase  revenue  across  our
operations,  including  reductions  in  our  number  of  manufacturing  facilities  and  workforce,  establishing  certain  operations  closer  in  location  to  our  global
customers and evaluating functions that may be more efficiently performed through outsourcing arrangements. For example, in June 2019, we committed to a
restructuring  plan  designed  to  streamline  and  improve  our  operations  that  included  the  refocusing  of  certain  research  and  development  activities  and  a
reduction in workforce. Any restructuring initiatives could result in potential adverse effects on employee capabilities, our continued ability to recruit, hire,
retain and motivate highly-skilled engineering, operations, sales, administrative, managerial and other key personnel, our ability to achieve design wins and
our ability to maintain and enhance our customer base. Such events could harm our efficiency and our ability to act quickly and effectively in the rapidly
changing technology markets in which we sell our products. In addition, we may be unsuccessful in our efforts to realign our organizational structure and shift
our  investments.  The  potential  negative  impact  of  a  restructuring  plan  on  our  employees  may  limit  our  ability  to  meet  and  satisfy  the  demands  of  our
customers and, as a result, have a material impact on our business, financial condition and results of operations.

Restructuring initiatives can be substantial in scope and involve large expenditures. For example, in fiscal year 2019, we incurred restructuring charges
of $19.5 million, consisting primarily of employee severance and related costs resulting from reductions in our workforce. Exiting a leased site may involve
contractual or negotiated exit payments with the landlord, temporary holding over at an increased lease rate, costs to perform restoration work required by the
lease  or  associated  environmental  liability,  any  of  which  may  be  material  in  amount.  Consolidation  of  operations  and  outsourcing  may  involve  substantial
capital expenses and the transfer of manufacturing processes and personnel from one site to another, with resultant startup issues at the receiving site and the
need  for  re-qualification  of  the  transitioned  operations  with  major  customers  and  for  ISO  or  other  certifications.  We  may  experience  shortages  of  affected
products, delays and higher than expected expenses. Affected employees may be distracted by the transition or seek other employment, which could cause our
overall operational efficiency to suffer. Any of these issues or our failure to realize the expected benefits of a restructuring initiative could harm our results of
operations and reduce the price of our common stock.

Risks Relating to Ownership of our Common Stock

We may engage in future capital-raising transactions that dilute the ownership of our existing stockholders or cause us to incur debt.

We may issue additional equity, debt or convertible securities to raise capital in the future. If we do, existing stockholders may experience significant
further dilution. In addition, new investors may demand rights, preferences or privileges that differ from or are senior to, those of our existing stockholders.
Our incurrence of indebtedness could limit our operating flexibility and be detrimental to our results of operations.

23

The market price of our common stock may be volatile, which could result in substantial losses for investors.

We cannot predict the prices at which our common stock will trade. The market price of our common stock may fluctuate significantly, depending upon
many factors, some of which may be beyond our control. In addition to the risks described in this Annual Report, other factors that may cause the market price
of  our  common  stock  to  fluctuate  include  changes  in  general  economic,  political,  industry  and  market  conditions;  general  market  price  and  volume
fluctuations, including volatility resulting from the COVID-19 pandemic; domestic and international economic factors unrelated to our performance; actual or
anticipated fluctuations in our quarterly operating results; changes in or failure to meet publicly disclosed expectations as to our future financial performance;
changes in securities analysts’ estimates of our financial performance, lack of research and reports by industry analysts or negative research and reports by
industry analysts; addition or loss of significant customers; announcements by us or our competitors, customers or suppliers of significant products, contracts,
acquisitions,  strategic  partnerships  or  other  events;  any  future  sales  of  our  common  stock  or  other  securities;  and  additions  or  departures  of  directors,
executives or key personnel.

For  example,  on  August  1,  2017  we  announced  results  of  operations  for  our  third  quarter  of  fiscal  year  2017  and  a  financial  outlook  for  our  fourth
quarter of fiscal year 2017 that were below the then-current consensus of securities analyst expectations. The closing price per share of our common stock
thereafter declined from $61.06 on August 1, 2017 to $45.50 on August 2, 2017, and further to $39.67 on August 18, 2017, representing a cumulative decline
of approximately 35.0%. In the past, companies that have experienced volatility in the market price of their stock have been subject to securities class action
litigation.  We  may  be  the  target  of  this  type  of  litigation  in  the  future.  Securities  litigation  against  us  could  result  in  substantial  costs  and  divert  our
management’s attention from other business concerns, which could seriously harm our business.

If we fail to maintain effective internal controls over financial reporting, we may not be able to accurately report our financial results, which could have a
material adverse effect on our operations, investor confidence in our business and the trading prices of our securities.

We are required to maintain disclosure controls and procedures and internal controls over financial reporting that are effective for the purposes described
in “Item  9A  -  Controls  and  Procedures”  below.  The  existence  of  a  material  weakness  in  our  internal  controls  may  adversely  affect  our  ability  to  record,
process, summarize and report financial information timely and accurately and, as a result, our financial statements may contain material misstatements or
omissions,  which  could  result  in  regulatory  scrutiny,  cause  investors  to  lose  confidence  in  our  reported  financial  condition  and  otherwise  have  a  material
adverse effect on our business, financial condition, cash flow results of operations or the trading price of our stock.

Some of our stockholders can exert control over us and they may not make decisions that reflect our interests or those of other stockholders.

Our largest stockholders control a significant amount of our outstanding common stock. As of October 1, 2021, John and Susan Ocampo beneficially
owned 26.6% of our common stock. As a result, these stockholders will be able to exert a significant degree of influence over our management and affairs and
control over matters requiring stockholder approval, including the election of our directors and approval of significant corporate transactions. In addition, this
concentration of ownership may delay or prevent a change in control of us and might affect the market price of our securities. In addition, the interests of these
stockholders may not always coincide with your interests or the interests of other stockholders.

Anti-takeover provisions in our charter documents and Delaware law could prevent or delay a change in control of our company that stockholders may
consider beneficial and may adversely affect the price of our stock.

Provisions  of  our  fifth  amended  and  restated  certificate  of  incorporation  and  third  amended  and  restated  bylaws  may  discourage,  delay  or  prevent  a
merger, acquisition or change of control that a stockholder may consider favorable. These provisions could also discourage proxy contests and make it more
difficult for stockholders to elect directors and take other corporate actions. The existence of these provisions could limit the price that investors might be
willing to pay in the future for shares of our common stock. These provisions include authorization of the issuance of “blank check” preferred stock, staggered
elections of directors and advance notice requirements for nominations for election to the board of directors and for proposing matters to be submitted to a
stockholder  vote.  Provisions  of  Delaware  law  may  also  discourage,  delay  or  prevent  someone  from  acquiring  or  merging  with  our  company  or  obtaining
control of our company. Specifically, Section 203 of the Delaware General Corporate Law may prohibit business combinations with stockholders owning 15%
or more of our outstanding voting stock. Our board of directors could rely on Delaware law to prevent or delay an acquisition of us and this reliance could
reduce our value.

We do not intend to pay dividends for the foreseeable future.

We do not intend to pay any cash dividends on our common stock in the foreseeable future. The payment of cash dividends is restricted under the terms
of the agreements governing our indebtedness. In addition, because we are a holding company, our ability to pay cash dividends may be limited by restrictions
on  our  ability  to  obtain  sufficient  funds  through  dividends  from  subsidiaries,  including  restrictions  under  the  terms  of  the  agreements  governing  our
indebtedness. We anticipate that we will retain all of our future earnings for use in the development of our business and for general corporate purposes. Any
determination to pay dividends in the future will be at the discretion of our board of directors. Accordingly, investors must rely on sales of their common stock
after price appreciation, which may never occur, as the only way to realize any future gains on their investments.

Risks Relating to our 2026 Convertible Notes

Servicing  our  debt,  including  the  2026  Convertible  Notes,  requires  a  significant  amount  of  cash,  and  we  may  not  have  sufficient  cash  flow  from  our
business to pay our indebtedness.

Our ability to make payments of the principal of, to pay interest on, or to refinance, the 2026 Convertible Notes, or to make cash payments in connection
with any conversion of the 2026 Convertible Notes depends on our future performance, which is subject to economic, financial, competitive and other factors
beyond our control. Our business may not continue to generate cash flow from operations in the future sufficient to service the 2026 Convertible Notes or
other  indebtedness  and  make  necessary  capital  expenditures.  If  we  are  unable  to  generate  such  cash  flow,  we  may  be  required  to  adopt  one  or  more
alternatives,  such  as  selling  assets,  restructuring  indebtedness  or  obtaining  additional  equity  capital  on  terms  that  may  be  onerous  or  highly  dilutive.  Our
ability to refinance the 2026 Convertible Notes or our other indebtedness will depend on the capital markets and our financial condition at such time. We may
not be able to engage in any of these activities or engage in these activities on desirable terms, which could result in a default on our debt obligations.

Provisions in indenture governing the 2026 Convertible Notes may delay or prevent an otherwise beneficial business combination.

The terms of the 2026 Convertible Notes require us to repurchase the 2026 Convertible Notes in the event of a “fundamental change” as defined under
the indenture governing the 2026 Convertible Notes. A fundamental change of our Company would trigger an option of the holders of the 2026 Convertible
Notes to require us to repurchase the 2026 Convertible Notes. In addition, if a make-whole fundamental change occurs prior to the maturity date of the 2026
Convertible  Notes,  we  will  in  some  cases  be  required  to  increase  the  conversion  rate  for  a  holder  that  elects  to  convert  its  2026  Convertible  Notes.
Furthermore, the indenture that governs the 2026 Convertible Notes prohibits us from engaging in certain mergers or acquisitions unless, among other things,
the  surviving  entity  assumes  our  obligations  under  the  2026  Convertible  Notes.  This  may  have  the  effect  of  delaying  or  preventing  an  acquisition  of  our
Company that could be beneficial to investors.

We may not have the ability to raise the funds necessary to settle conversions of the 2026 Convertible Notes in cash or to repurchase the 2026 Convertible
Notes upon a fundamental change and our debt may limit our ability to pay cash upon conversion or repurchase of the 2026 Convertible Notes.

Holders of the 2026 Convertible Notes have the right to require us to repurchase their 2026 Convertible Notes upon the occurrence of a fundamental
change at a purchase price equal to 100% of the principal amount of the 2026 Convertible Notes to be repurchased, plus accrued and unpaid interest, if any, to,
but not including, the fundamental change repurchase date. In addition, unless we elect to deliver solely shares of our common stock upon conversion, we will
be required to make cash payments in respect of the 2026 Convertible Notes being converted. However, we may not have enough available cash or be able to
obtain financing at the time we are required to make purchases of the 2026 Convertible Notes, and our failure to do so would constitute a default under the
indenture governing the 2026 Convertible Notes. In addition, our ability to repurchase the 2026 Convertible Notes or to pay cash upon conversion of the 2026
Convertible Notes could be limited by law, by regulatory authority or by agreements that will govern our future indebtedness. A default under the indenture
governing  the  2026  Convertible  Notes  or  the  fundamental  change  itself  could  also  lead  to  a  default  under  agreements  governing  our  existing  or  future
indebtedness.

ITEM 6. [RESERVED]

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATION.

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our consolidated financial
statements and related notes that appear elsewhere in this Annual Report. In addition to historical information, the following discussion contains forward-
looking  statements  that  are  subject  to  risks  and  uncertainties.  Actual  results  may  differ  substantially  and  adversely  from  those  referred  to  herein  due  to  a
number of factors, including but not limited to those described below and in “Item 1A - Risk Factors” and elsewhere in this Annual Report.

OVERVIEW

We design and manufacture semiconductor products for Telecom, I&D and Data Center applications. Headquartered in Lowell, Massachusetts, we have
more than 70 years of application expertise, with silicon, GaAs and InP fabrication, manufacturing, assembly and test, and operational facilities throughout
North  America,  Europe  and  Asia.  We  design,  develop  and  manufacture  differentiated,  high-value  products  for  customers  who  demand  high  performance,
quality and reliability. We offer a broad portfolio of thousands of standard and custom devices, which include ICs, MCMs, diodes, amplifiers, switches and
switch limiters, passive and active components and complete subsystems, across dozens of product lines serving over 6,000 end customers in three primary
markets.  Our  semiconductor  products  are  electronic  components  that  our  customers  generally  incorporate  into  larger  electronic  systems,  such  as,  wireless
basestations, high capacity optical networks, radar, medical systems and test and measurement. Our primary markets are: (1) Telecom, which includes carrier
infrastructure such as long-haul/metro, 5G and FTTx/PON, among others; (2) I&D, which includes military and commercial radar, RF jammers, electronic
countermeasures, communication data links, satellite communications and multi-market applications, which include industrial, medical, test and measurement
and  scientific  applications;  and  (3)  Data  Center,  enabled  by  our  broad  portfolio  of  analog  ICs  and  photonic  components  for  high  speed  optical  module
customers.

See “Item 1 - Business” for additional information.

Basis of Presentation

We have one reportable operating segment and all intercompany balances have been eliminated in consolidation.

We have a 52 or 53-week fiscal year ending on the Friday closest to the last day of September. Fiscal years 2021 and 2019 each consisted of 52 weeks,
and fiscal year 2020 included 53 weeks. To offset the effect of holidays, for fiscal years in which there are 53 weeks, we typically include the extra week in the
first quarter of our fiscal year. Our first quarter of fiscal year 2020, ended January 3,

27

2020, included 14 weeks.

Description of Our Revenue

Revenue.  Our  revenue  is  derived  from  sales  of  high-performance  RF,  microwave,  millimeter  wave,  optical  and  photonic  semiconductor  products.  We
design, integrate, manufacture and package differentiated, semiconductor-based products that we sell to customers through our direct sales organization, our
network of independent sales representatives and our distributors. We believe the primary drivers of our future revenue growth will include:

•

•

•

•

•

continued growth in the demand for high-performance analog, digital and optical semiconductors in our three primary markets;

introducing new products using advanced technologies, added features, higher levels of integration and improved performance;

increasing content of our semiconductor solutions in customers’ systems through cross-selling our product lines;

leveraging our core strength and leadership position in standard, catalog products that service all of our end applications; and

engaging early with our lead customers to develop custom and standard products.

Our core strategy is to develop and innovate high-performance products that address our customers’ most difficult technical challenges in our primary

markets: Telecom, I&D and Data Center.

We expect our revenue in the Telecom market to be driven by 5G deployments, with continued upgrades and expansion of communications equipment,

and increasing adoption of our high-performance RF, millimeter wave, optical and photonic components.

We  expect  our  revenue  in  the  I&D  market  to  be  driven  by  the  expanding  product  portfolio  that  we  offer  which  services  applications  such  as  test  and
measurement, satellite communications, civil and military radar, industrial, scientific and medical applications, further supported by growth in applications for
our multi-market catalog products.

We expect our revenue in the Data Center market to be driven by the adoption of cloud-based services and the upgrade of data center architectures, to

100G, 200G, 400G and 800G interconnects, which we expect will drive adoption of higher speed optical and photonic components.

COVID-19 Impact

See “Item 1 - Business.” For additional information on risk factors that could impact our future results, please refer to “Item 1A - Risk Factors” in this

Annual Report.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Our discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements. The preparation of
financial  statements,  in  conformity  with  generally  accepted  accounting  principles  in  the  U.S.,  requires  management  to  make  estimates  and  judgments  that
affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported
amounts of revenue and expenses during the reporting period. By their nature, these estimates and judgments are subject to an inherent degree of uncertainty
and could be material if our actual or expected experience were to change unexpectedly. On an ongoing basis, we re-evaluate our estimates and judgments.

Due to the COVID-19 pandemic, there has been uncertainty and disruption in the global economy and financial markets. We are not aware of any specific
event or circumstance that would require updates to our estimates or judgments or require us to revise the carrying value of our assets or liabilities as of the
date of filing of this Annual Report on Form 10-K with the SEC. These estimates may change as new events occur and additional information is obtained.
Actual results could differ materially from these estimates under different assumptions or conditions.

We base our estimates and judgments on our historical experience and on other assumptions that we believe are reasonable under the circumstances, the
results of which form the basis for making the judgments about the carrying values of assets and liabilities that are not readily apparent from other sources.
Actual results could differ from those estimates and material effects on our operating results and financial position may result. The accounting policies which
our  management  believes  involve  the  most  significant  application  of  judgment  or  involve  complex  estimation,  are  inventories  and  associated  reserves;
goodwill and long-lived asset valuations and associated impairment assessments; revenue reserves; share-based compensation valuations and income taxes.

When we evaluate inventory for excess quantities and obsolescence, we utilize historical product usage experience and expected demand for establishing
our reserve estimates. Our actual product usage may vary from the historical experience and estimating demand is inherently difficult, particularly given the
cyclical nature of the semiconductor industry, both of these factors may result in us recording excess and obsolete inventory amounts that do not match the
required amounts.

28

Our  goodwill  impairment  assessment  requires  management  to  make  assumptions  and  to  apply  judgment  to  items  such  as  the  determination  of  the

reporting unit.

Significant management judgment is required in our valuation of long-lived asset groups when assessing for potential impairment. These analyses are
based on the creation of forecasts of future operating results that are used in the valuation, including estimation of (i) future cash flows, (ii) the long-term rate
of growth for our business, (iii) the useful life over which cash flows will occur, (iv) terminal values, if applicable, and (v) the determination of our weighted
average cost of capital, which is used to determine the discount rate. It is possible that these forecasts may change and our projections included in our forecasts
of future results may prove to be inaccurate. If our actual results, or the forecasts and estimates used in future impairment analyses, are lower than the original
estimates used to assess the recoverability of these assets, we could incur impairment charges. Our forecasts and the value of our long-lived asset groups could
be adversely affected by, but not limited to, a change in strategy, the outcome of development activities, a significant slowdown in our primary markets, the
semiconductor industry or worldwide economy, or a decline in the valuation of technology company stocks, including the valuation of our common stock.

We establish revenue reserves, primarily for distributor price adjustments, which requires the use of judgment and estimates that impact the amount and
timing of revenue recognition. We record reductions of revenue for such distributor pricing adjustments in the same period that the related revenue is recorded
based on estimates of historical pricing adjustments granted to distributors. The actual pricing adjustments granted to distributors may significantly exceed or
be less than the historical estimates resulting in adjustments to revenue in the incorrect period.

We account for share-based compensation arrangements using the fair value method as described in Note 2 - Summary of Significant Accounting Policies
to our Consolidated Financial Statements in this Annual Report. There are a significant number of estimates and assumptions required for the initial valuation
as  well  as  for  the  ongoing  valuation  of  certain  share-based  compensation  items.  These  estimates  may  vary  significantly  and  the  assumptions  may  not  be
accurate resulting us to make adjustments to historically recorded balances.

We are required to estimate our income taxes in each of the jurisdictions in which we operate. This process involves estimating our actual current tax
exposure together with assessing temporary differences resulting from differing treatment of items for tax and accounting purposes. These differences result in
deferred tax assets and liabilities, which are included within our Consolidated Balance Sheets. We then assess the likelihood that our deferred tax assets will be
recovered from future taxable income within the relevant jurisdiction and to the extent we believe that recovery is not likely, we must establish a valuation
allowance. We provide valuation allowances for certain of our deferred tax assets, where it is more likely than not that some portion, or all of such assets, will
not be realized.

The application of tax laws and regulations to calculate our tax liabilities is subject to legal and factual interpretation, judgment, and uncertainty in a
multitude  of  jurisdictions.  Tax  laws  and  regulations  themselves  are  subject  to  change  as  a  result  of  changes  in  fiscal  policy,  changes  in  legislation,  the
evolution of regulations, and court rulings. We recognize potential liabilities for anticipated tax audit issues in the United States and other tax jurisdictions
based on our estimate of whether, and the extent to which, additional taxes and interest will be due. We record an amount as an estimate of probable additional
income tax liability at the largest amount that we feel is more likely than not, based upon the technical merits of the position, to be sustained upon audit by the
relevant tax authority. 

Historically, we have not experienced material differences in our estimates and actual results.

For  additional  information  related  to  these  and  other  accounting  policies  refer  to  Note  2  -  Summary  of  Significant  Accounting  Policies  to  our

Consolidated Financial Statements included in this Annual Report which is incorporated by reference herein.

In fiscal year 2021, our Telecom market revenue decreased by $21.1 million, or 10.1%, compared to fiscal year 2020. The decrease was primarily driven
by  a  decrease  in  carrier-based  optical  semiconductor  products,  including  those  targeted  for  5G  applications,  offset  by  increased  sales  of  legacy  products,
including products targeting fiber to the home, CATV infrastructure and licensing revenue.

In fiscal year 2021, our I&D market revenue increased by $85.7 million, or 44.1%, compared to fiscal year 2020. The increase was primarily related to

new program wins and expansion of our RF and microwave product lines.

In fiscal year 2021, our Data Center market revenue increased by $12.3 million, or 9.8%, compared to fiscal year 2020. The increase was primarily due

to increased sales of our high-performance analog and optoelectronics Data Center products.

Gross profit. In fiscal year 2021, our gross profit increased by $71.7 million, or 26.5%, compared to fiscal year 2020. Gross margin of 56.3% in fiscal
year 2021 increased 530 basis points, compared to fiscal year 2020. The increase in gross profit during 2021 was primarily the result of higher sales, favorable
revenue mix, production efficiencies, as well as decreases in depreciation and amortization.

Research and development. In fiscal year 2021, research and development expense decreased by $2.5 million, or 1.8%, to $138.8 million representing
22.9% of revenue, compared with $141.3 million, representing 26.7% of revenue in fiscal year 2020. Research and development expense decreased during
fiscal year 2021 primarily as a result of decreased spending on software and lower depreciation, partially offset by higher supplies expense, foundry costs and
outside service costs.

31

Selling,  general  and  administrative.  In  fiscal  year  2021,  selling,  general  and  administrative  expenses  decreased  by  $2.3  million,  or  1.8%,  to  $122.0
million, or 20.1% of revenue, compared with $124.3 million, or 23.5% of revenue, for fiscal year 2020. Selling, general and administrative expenses decreased
during fiscal year 2021 primarily due to lower depreciation, amortization and other outside service costs, offset by an increase in variable selling costs.

Restructuring charges. There were no restructuring charges incurred during fiscal year 2021, compared with $1.1 million, or 0.2% of our revenue, for
fiscal year 2020. All restructuring actions were completed as of October 2, 2020. Refer to Note 12 - Restructurings in this Annual Report on Form 10-K for
additional information.

Warrant liability gain. In fiscal year 2021, we recorded warrant expense of $11.1 million, or 1.8% of revenue, compared to an expense of $12.9 million,
or  2.4%  of  revenue,  for  fiscal  year  2020.  The  difference  between  periods  was  driven  by  a  change  in  the  estimated  fair  value  of  common  stock  warrants,
primarily driven by the increase in the underlying price of our common stock, which was recorded as a liability at fair value. During November 2020, all of
the  warrants  were  exercised  and  857,631  shares  of  common  stock  were  issued.  As  of  October  1,  2021,  there  are  no  remaining  common  stock  warrants
outstanding. See Note 19 - Stockholders' Equity in this Annual Report for additional information regarding the common stock warrants.

Interest expense, net. In fiscal year 2021, interest expense, net was $20.6 million, or 3.4% of our revenue, compared to $27.4 million, or 5.2% of our
revenue, for fiscal year 2020. The decrease in fiscal year 2021 is primarily due to a lower effective interest rate on our Term Loans and the decrease in our
long-term debt balance.

Provision for income taxes. In fiscal year 2021, income tax expense was $5.0 million, or 0.8% of revenue, compared to an expense of $4.5 million, or

0.9% of revenue, for fiscal year 2020. The change in the provision is primarily due to a change in the valuation allowance.

The difference between the U.S. federal income tax rate of 21% and our effective income tax rate of 11.6% for fiscal year 2021 was primarily driven by
the continuation of a full valuation allowance against any tax expense associated with U.S. income and income taxed in foreign jurisdictions at generally lower
tax rates. For fiscal year 2020, our effective income tax rate of (10.9)% was primarily impacted by the continuation of a full valuation allowance against any
benefit associated with U.S. losses and income taxed in foreign jurisdictions at generally lower tax rates.

Comparison of Fiscal Year Ended October 2, 2020 to Fiscal Year Ended September 27, 2019

Revenue. In fiscal year 2020, our revenue increased by $30.3 million, or 6.1%, to $530.0 million from $499.7 million for fiscal year 2019. Fiscal year

2020 included 53 weeks and fiscal year 2019 consisted of 52 weeks. Our first quarter of fiscal year 2020, ended January 3, 2020, included 14 weeks.

In fiscal year 2020, our Telecom market revenue increased by $28.5 million, or 15.8%, compared to fiscal year 2019. The increase was primarily driven
by increased sales of carrier-based optical semiconductor products, including those targeted for 5G applications, primarily to our Asia customer base, partially
offset by lower sales of legacy products.

In fiscal year 2020, our I&D market revenue decreased by $10.1 million, or 5.0%, compared to fiscal year 2019. The decrease was primarily related to

the decline in certain defense-related programs and lower sales of certain legacy product lines.

In fiscal year 2020, our Data Center market revenue increased by $11.9 million, or 10.4%, compared to fiscal year 2019. The increase was primarily due

to increased sales of our high-performance analog Data Center products.

Gross profit. In fiscal year 2020, our gross profit increased by $49.5 million, or 22.4%, compared to fiscal year 2019. Gross margin of 51.0% in fiscal
year  2020  increased  680  basis  points,  compared  to  fiscal  year  2019.  The  increase  in  gross  profit  during  2020  was  primarily  the  result  of  lower  inventory
reserve  expenses  and  the  strategic  realignment  of  our  business  under  the  2019  Plan  (as  defined  below),  resulting  in  lower  compensation-related  costs  and
intangible amortization.

32

 
Research and development. In fiscal year 2020, research and development expense decreased by $22.1 million, or 13.5%, to $141.3 million representing
26.7% of revenue, compared with $163.5 million, representing 32.7% of revenue in fiscal year 2019. Research and development expense decreased during
fiscal year 2020 primarily as a result of the strategic realignment of our business and operations under the 2019 Plan, resulting in lower compensation and
research and development related costs, partially offset by higher share-based compensation expense.

Selling, general and administrative. In fiscal year 2020, selling, general and administrative expenses decreased by $29.0 million, or 18.9%, to $124.3
million, or 23.5% of revenue, compared with $153.3 million, or 30.7% of revenue, for fiscal year 2019. Selling, general and administrative expenses decreased
during fiscal year 2020 primarily due to lower intangible amortization expense, decreased discretionary spending, such as external services and travel, offset
by an increase in share-based compensation expense.

Impairment  charges.  In  fiscal  year  2019,  impairment  charges  were  $264.8  million,  or  53.0%  of  revenue,  primarily  related  to  the  $257.0  million
impairment  of  intangible  assets,  as  well  as  the  impairment  of  $7.1  million  of  equipment  from  construction  in  process  that  was  not  placed  in  service.  See
Note 10 - Impairments to the Consolidated Financial Statements included in this Annual Report for additional information.

Restructuring charges. In fiscal year 2020, restructuring charges were $1.1 million, or 0.2% of our revenue, compared with $19.5 million, or 3.9% of our

revenue, for fiscal year 2019. In fiscal year 2019, restructuring charges primarily related to the 2019 Plan and the Ithaca Plan, each as defined below.

During the third quarter of fiscal 2019, we committed to a plan to strategically realign, streamline and improve certain of our business and operations,
including reducing our workforce by approximately 250 employees, and exiting multiple development facilities, reducing certain development activities for
one of our product lines and no longer investing in the design and development of optical modules and subsystems for Data Center applications (the “2019
Plan”).  During  the  fiscal  year  ended  October  2,  2020,  we  incurred  restructuring  expenses  of  $1.2  million  under  the  2019  Plan,  including  $0.8  million  of
facility-related costs and $0.4 million of employee-related costs. We incurred restructuring charges of $11.6 million in fiscal year 2019, including $6.3 million
of  employee-related  costs,  $4.0  million  of  impairment  expense  for  fixed  assets  and  $1.3  million  of  other  facility-related  costs.  This  action  was  completed
during fiscal 2020 and the remaining charges were paid during fiscal year 2021.

During the fiscal quarter ended September 28, 2018, we committed to a plan to exit certain production and product lines, primarily related to certain
production facilities located in Ithaca, New York (the “Ithaca Plan”). For these facilities, we incurred $5.5 million of restructuring charges in the fiscal year
ended September 27, 2019, including $1.5 million of employee-related costs and $4.0 million of facility-related costs. This action was completed in fiscal year
2019 and no further costs were incurred.

Refer to Note 12 - Restructurings in this Annual Report on Form 10-K for additional information.

Warrant liability gain. In fiscal year 2020, we recorded warrant expense of $12.9 million, or 2.4% of revenue, compared to a gain of $0.8 million, or
0.2% of revenue, for fiscal year 2019. The difference between periods was driven by an increase in the estimated fair value of common stock warrants we
issued  in  December  2010,  which  we  carry  as  a  liability  at  fair  value.  Substantially  all  of  the  warrants  were  exercised  and  common  stock  was  issued  on
November 11, 2020. See Note 19 - Stockholders' Equity in this Annual Report for additional information regarding the common stock warrants.

Provision for income taxes. In fiscal year 2020, income tax expense was $4.5 million, or 0.9% of revenue, compared to a benefit of $39.4 million, or
7.9% of revenue, for fiscal year 2019. The change in the provision is primarily due to recognition of current and deferred income tax effects totaling $39.8
million during fiscal year 2019, from an intra-entity transfer of a license for intellectual property between foreign tax jurisdictions that received a tax basis
step-up, with no similar benefit during fiscal year 2020.

The difference between the U.S. federal income tax rate of 21% and our effective income tax rate of (10.9)% for fiscal year 2020 was primarily driven
by the continuation of a full valuation allowance against any benefit associated with U.S. losses and income taxed in foreign jurisdictions at generally lower
tax rates. For fiscal year 2019, our effective income tax rate of 9.3% was primarily impacted by the reduction of our NOLs from Section 382 limitations, the
immediate  recognition  of  the  current  and  deferred  income  tax  effects  of  an  intra-entity  transfer  of  a  license  for  intellectual  property  and  the  valuation
allowance against our U.S. deferred tax assets.

Our  cash  flow  from  operating  activities  for  fiscal  year  2021  was  $148.4  million  and  consisted  of  a  net  income  of  $38.0  million,  plus  adjustments  to
reconcile  our  net  income  to  cash  provided  by  operating  activities  of  $136.4  million,  partially  offset  by  changes  in  operating  assets  and  liabilities of $25.9
million. Adjustments to reconcile our net income  to  cash  provided  by  operating  activities  of  $136.4  million  primarily  included  depreciation  and  intangible
amortization  expense  of  $70.0  million,  share-based  compensation  expense  of  $35.0  million,  warrant  liability  expense  of  $11.1  million,  accretion  of  the
discount on convertible debt of $7.6 million and deferred financing cost amortization and write offs of $6.5 million. In addition, cash used by operating assets
and liabilities was $25.9 million for fiscal year 2021, primarily driven by an increase in accounts receivable of $38.7 million due to timing of sales, partially
offset by a decrease in inventory of $8.9 million and an increase in accounts payable of $5.8 million.

Our cash flow from operating activities for fiscal year 2020 was $171.4 million and consisted of a net loss of $46.1 million, plus adjustments to reconcile
our  net  loss  to  cash  provided  by  operating  activities  of  $142.1  million  plus  changes  in  operating  assets  and  liabilities  of  $75.5  million.  Adjustments  to
reconcile our net loss to cash provided by operating activities of $142.1 million primarily included depreciation and intangible amortization expense of $78.8
million,  share-based  compensation  expense  of  $35.7  million,  warrant  liability  expense  of  $12.9  million,  impairment  and  net  loss  on  minority  equity
investments of $5.9 million, amortization of deferred financing costs of $4.1 million and a decrease in deferred tax assets of $3.3 million. In addition, cash
from  operating  assets  and  liabilities  was  $75.5  million  for  fiscal  year  2020,  primarily  driven  by  a  decrease  in  accounts  receivable  of  $23.9  million  due  to
improved revenue linearity, a decrease in inventory of $16.3 million, a decrease in income tax receivable of $14.9 million and a decrease in prepaid expenses
and other assets of $18.1 million.

Cash Flow from Investing Activities:

Our cash flow used in investing activities for fiscal year 2021 consisted primarily of $194.2 million in purchases of short-term investments and capital

expenditures of $18.0 million, partially offset by proceeds of $209.3 million related to the sale and maturities of short-term investments.

Our cash flow used in investing activities for fiscal year 2020 consisted primarily of $284.9 million in purchases of short-term investments, proceeds of
$183.9 million related to the sale and maturities of short-term investments, capital expenditures of $17.6 million and proceeds of $11.0 million associated with
our divestment in May 2018 of certain capital equipment, inventory and other assets in Japan associated with the LR4 business.

Cash Flow from Financing Activities:

During fiscal year  2021,  our  cash  used  in  financing  activities  of  $119.1  million  was  primarily  related  to  $545.3  million  of  prepayments  on  our  Term
Loans  (as  defined  in  Note  16  -  Debt  to  our  Consolidated  Financial  Statements  included  in  this  Annual  Report)  and  $23.4  million  of  repurchases  of  stock
associated  with  employee  tax  withholdings  on  vested  equity  awards,  partially  offset  by  proceeds  of  $450.0  million  from  the  2026  Convertible  Notes  (as
defined in Note 16 - Debt to our Consolidated Financial Statements included in this Annual Report) and $6.8 million of proceeds from stock option exercises
and employee stock purchases. The early prepayment on the Term Loans of $543.6 million was made using $443.6 million of net proceeds from our 2026
Convertible Notes and cash of $100.0 million. See Note 16 - Debt to  our  Consolidated  Financial  Statements  included  in  this  Annual  Report  for  additional
information.

During fiscal year 2020, our cash used in financing activities of $10.7 million was primarily related to $6.9 million of principal payments associated with
our Term Loans (as defined in Note 16 - Debt to our Consolidated Financial Statements included in this Annual Report) and $6.7 million in purchases of stock
associated with employee tax withholdings, partially offset by $4.6 million of proceeds from stock option exercises and employee stock purchases.

Liquidity

As of October 1, 2021, we held $156.5 million of cash and cash equivalents, primarily deposited with financial institutions as well as $188.4 million of
liquid short-term investments. The undistributed earnings of certain foreign subsidiaries are considered indefinitely reinvested for the periods presented and
we  do  not  intend  to  repatriate  such  earnings.  We  believe  the  decision  to  reinvest  these  earnings  will  not  have  a  significant  impact  on  our  liquidity.  As  of
October 1, 2021, cash held by our indefinitely reinvested foreign subsidiaries was $27.1 million, which, along with cash generated from foreign operations, is
expected to be used in the support of international growth and working capital requirements as well as the repayment of certain intercompany loans. As of
October  1,  2021,  we  had  $160.0  million  in  borrowing  capacity  under  our  Revolving  Facility  (as  defined  in  Note  16  -  Debt  to  our  Consolidated  Financial
Statements included in this Annual Report) that expired undrawn on November 8, 2021.

We  plan  to  use  our  remaining  available  cash  and  cash  equivalents  as  well  as  our  short-term  investments  for  general  corporate  purposes,  including
working capital, or for the acquisition of or investment in complementary technologies, design teams, products and businesses. We believe that our cash and
cash equivalents, short-term investments and cash generated from operations will be sufficient to meet our working capital requirements for at least the next
twelve months. We may need to raise additional capital from time to time through the issuance and sale of equity or debt securities, and there is no assurance
that we will be able do so on favorable terms or at all.

As of October 1, 2021, we had no off-balance sheet arrangements.

(1) Our Term Loans will mature in May 2024 and our 2026 Convertible Notes will mature in March 2026. The interest rate on the Term Loans is variable, which may
result in changes to our interest obligations. See Note 16 - Debt to the Consolidated Financial Statements included in this Annual Report for additional information.

(2) Estimated future lease payments, see Note 18 - Leases to the Consolidated Financial Statements included in this Annual Report for additional information.
(3) We have purchase commitments of $108.0 million primarily related to services and inventory supply arrangements of which approximately $82.7 million that is non-
cancelable. In addition, we have $27.2 million in fixed payments associated with a power purchase agreement that is expected to commence in fiscal 2022 and has a
15-year term. See Note 17- Financing Obligation for additional detail on the power purchase agreement.

As of October 1, 2021, we estimated $1.9 million in asset retirement obligations primarily for the restoration of leased facilities upon the termination of
the related leases. Although it is reasonably possible that our estimates could change materially in the next twelve months, we are presently unable to reliably
estimate when any cash settlement of these obligations may occur.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We  are  exposed  to  market  risk  in  the  ordinary  course  of  business,  which  consists  primarily  of  interest  rate  risk  associated  with  our  cash  and  cash

equivalents, short-term investments and our variable rate debt, as well as foreign exchange rate risk.

Interest rate risk. The primary objectives of our investment activity are to preserve principal, provide liquidity and invest excess cash for an average rate
of  return.  To  minimize  market  risk,  we  maintain  our  portfolio  in  cash  and  diversified  investments,  which  may  consist  of  corporate  bonds,  bank  deposits,
money market funds and commercial paper. The interest rates are variable and fluctuate with current market conditions. The risk associated with fluctuating
interest rates is limited to this investment portfolio. We believe that a 10% change in interest rates would not have a material impact on our financial position
or results of operations. We do not enter into financial instruments for trading or speculative purposes.

Our exposure to interest rate risk also relates to the increase or decrease in the amount of interest expense we must pay on the outstanding debt under the

Credit Agreement. The interest rates on our term loans are variable interest rates based on our lender’s

35

 
prime rate or a LIBOR rate, in each case plus an applicable margin, which exposes us to market interest rate risk when we have outstanding borrowings under
the Credit Agreement. As of October 1, 2021, we had $120.8 million of outstanding borrowings under the Credit Agreement. Assuming our outstanding debt
remains  constant  under  the  Credit  Agreement  for  an  entire  year  and  the  applicable  annual  interest  rate  increases  or  decreases  by  1%,  our  annual  interest
expense would increase or decrease by $1.2 million.

Foreign currency risk. To date, our international customer agreements have been denominated primarily in U.S. dollars. Accordingly, we have limited
exposure to foreign currency exchange rates. The functional currency of a majority of our foreign operations continues to be in U.S. dollars with the remaining
operations being local currency. Changes in the value of the U.S. dollar relative to other currencies could make our products more expensive, which could
negatively impact demand in certain regions, reduce or delay customer orders, or otherwise negatively affect how customers do business with us. The effects
of exchange rate fluctuations on the net assets of the majority of our operations are accounted for as transaction gains or losses. We believe that a change of
10% in such foreign currency exchange rates would not have a material impact on our financial position or results of operations. In the future, we may enter
into foreign currency exchange hedging contracts to reduce our exposure to changes in exchange rates.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the stockholders and the Board of Directors of MACOM Technology Solutions Holdings, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of MACOM Technology Solutions Holdings, Inc. and subsidiaries (the “Company”) as
of October 1, 2021 and October 2, 2020, and the related consolidated statements of operations, comprehensive income (loss), stockholders’ equity, and cash
flows, for each of the three years in the period ended October 1, 2021, and the related notes (collectively referred to as the "financial statements"). In our
opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of October 1, 2021 and October 2, 2020, and
the  results  of  its  operations  and  its  cash  flows  for  each  of  the  three  years  in  the  period  ended  October  1,  2021,  in  conformity  with  accounting  principles
generally accepted in the United States of America.

We have also 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 October 1, 2021, based on criteria established in Internal Control - Integrated Framework (2013) issued by the
Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission  and  our  report  dated  November  15,  2021,  expressed  an  unqualified  opinion  on  the
Company's internal control over financial reporting.

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 Matter

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

Inventories – Excess Quantities and Obsolescence — Refer to Notes 2 and 7 to the financial statements

Critical Audit Matter Description

The Company evaluates inventory each reporting period for excess quantities and obsolescence, establishing reserves when necessary based upon historical
experience, assessment of economic conditions, and expected demand. Once recorded, these reserves are considered permanent adjustments to the carrying
value of inventory. As of October 1, 2021, the Company has inventories of $82.7 million, net of excess quantities and obsolescence reserves.

We  identified  the  reserve  for  excess  quantities  and  obsolete  inventory  as  a  critical  audit  matter  because  of  the  significant  estimates  and  assumptions
management makes to quantify and to record the reserve, including the determination of expected demand especially when considering the cyclical nature of
the semiconductor industry. This required a high degree of auditor judgment and an increased extent of effort when performing audit procedures to evaluate
the methodology and the reasonableness of assumptions including expected demand.

38

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the reserve for excess quantities and obsolete inventory including management’s estimate of expected demand, included the
following, among others:

• We tested the effectiveness of controls over inventory, including those over the estimation of reserves for excess quantities and obsolescence and the

review of any adjustments to the reserve methodology.

• We  selected  a  sample  of  inventory  parts  and  performed  corroborative  inquiry  with  product  line  managers  associated  with  the  selected  part  to
corroborate  our  understanding  of  the  expected  demand  and  historical  consumption  of  the  part  including  future  sales  plans,  product  life  cycle,  and
utilization in other products. For each selected part we tested the calculation of the excess and obsolete reserve pursuant to the Company's policy.

• We  held  discussions  with  senior  financial  and  operations  management  to  determine  that  any  strategic,  regulatory,  or  operational  changes  in  the

business were consistent with the projections of future demand that were utilized as the basis for the reserves recorded.

• We performed a retrospective review by comparing management’s prior year projections of future demand by product with actual product sales in the

current year to identify potential bias in the inventory reserve.

• We compared the Company’s inventory reserve assumptions to events and trends discussed in industry and analyst reports, disclosed in recent press
releases from the Company’s major customers (including financial information), and other industry data. In addition, we also considered any changes
within the business including restructuring events and strategic changes.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. DESCRIPTION OF BUSINESS

MACOM Technology Solutions Holdings, Inc. (the “Company”) was incorporated in Delaware on March 25, 2009. We are a leading provider of high-
performance analog semiconductor solutions that enable next-generation Internet applications, the cloud connected apps economy, and the modern, networked
battlefield across the RF, microwave, millimeter wave and lightwave spectrum. We design, develop, manufacture and have manufactured differentiated, high-
value products for customers who demand high performance, quality and reliability.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles  of  Consolidation,  Basis  of  Presentation  and  Reclassification—We  have  one  reportable  operating  segment  that  designs,  develops,
manufactures and markets semiconductors and modules. The accompanying consolidated financial statements include our accounts and the accounts of our
majority-owned  subsidiaries.  All  intercompany  balances  and  transactions  have  been  eliminated  in  consolidation.  In  the  Consolidated  Balance  Sheets  and
Notes Consolidated Financial Statements, certain prior year balances have been reclassified to conform to the current year presentation.

We have a 52- or 53-week fiscal year ending on the Friday closest to the last day of September. Fiscal years 2021 and 2019 included 52 weeks, and fiscal
year 2020 included 53 weeks. To offset the effect of holidays, for fiscal years in which there are 53 weeks, we typically include the extra week arising in our
fiscal years in the first quarter. Our first quarter of fiscal year 2020, ended January 3, 2020, included 14 weeks.

  Use  of  Estimates—The  preparation  of  consolidated  financial  statements  in  conformity  with  accounting  principles  generally  accepted  in  the  U.S.
requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities during the reporting periods, the reported
amounts of revenue and expenses during the reporting periods and the disclosure of contingent assets and liabilities at the date of the financial statements. On
an  ongoing  basis,  we  base  estimates  and  assumptions  on  historical  experience,  currently  available  information  and  various  other  factors  that  management
believes to be reasonable under the circumstances. Actual results may differ from these estimates and assumptions.

Foreign Currency Translation and Remeasurement—Our consolidated financial statements are presented in U.S. dollars. While the majority of our
foreign operations use the U.S. dollar as the functional currency, the financial statements of our foreign operations for which the functional currency is not the
U.S. dollar are translated into U.S. dollars at the exchange rates in effect at the balance sheet dates (for assets and liabilities) and at average exchange rates (for
revenue and expenses). The unrealized translation gains and losses on the net investment in these foreign operations are accumulated as a component of other
comprehensive (loss) income.

The financial statements of our foreign operations where the functional currency is the U.S. dollar, but where the underlying transactions are transacted
in a different currency, are remeasured at the exchange rate in effect at the balance sheet date with respect to monetary assets and liabilities. Nonmonetary
assets and liabilities, such as inventories and property and equipment and related statements of operations accounts, such as cost of revenue and depreciation,
are remeasured at historical exchange rates. Revenue and expenses, other than cost of revenue, amortization and depreciation, are translated at the average
exchange rate for the period in which the transaction occurred. The net gains and losses on foreign currency remeasurement are reflected in selling, general
and  administrative  expense  in  the  accompanying  Consolidated  Statements  of  Operations.  Net  foreign  exchange  transaction  gains  and  losses  for  all  periods
presented were not material.

Cash and Cash Equivalents—Cash equivalents are primarily composed of short-term, highly-liquid instruments with an original maturity of 90 days or

less and consist primarily of money market funds.

Investments— Short-term investments: We classify our short-term investments as available-for-sale. Our investments classified as available-for-sale are
recorded  at  fair  value  at  period  end.  Unrealized  gains  and  losses  that  are  deemed  to  be  unrelated  to  credit  losses  are  recorded  in  accumulated  other
comprehensive income and loss as a separate component of stockholders’ equity.

A  decline  in  the  fair  value  of  any  debt  security  below  cost  that  is  deemed  to  be  attributable  to  credit  loss  results  in  a  charge  to  earnings  and  the
corresponding establishment of an allowance for credit losses against the cost basis of the security. Premiums and discounts are amortized (accreted) over the
life of the related security as an adjustment to its yield. Dividend and interest income are recognized when earned. Realized gains and losses are included in
Other  expense,  net  in  our  Consolidated  Statements  of  Operations  and  are  derived  using  the  specific  identification  method  for  determining  the  cost  of
investments sold.

Other  investments:  We  use  the  equity  method  to  account  for  investments  in  companies  if  the  investment  provides  us  with  the  ability  to  exercise
significant influence over operating and financial policies of the investee. Our proportionate share of the net income (loss) resulting from these investments are
reported within the Other expense, net line in our Consolidated Statements of Operations.

45

The carrying value of our equity method investment is reported in Other investments in our Consolidated Balance Sheets. Our equity method investment
is reported at cost and adjusted each period for our share of the investee’s income or loss and dividends paid, if any, as well as any changes attributable to the
equity of the investee that would impact our ownership.

Other investments that are not controlled, and over which we do not have the ability to exercise significant influence, are accounted for as an equity
security and reported in Other investments in our Consolidated Balance Sheets. We have elected to measure our equity security, which does not have a readily
determinable fair value and does not qualify for the practical expedient under Accounting Standards Codification (“ASC”) 820, Fair Value Measurement, at
cost less any impairment. The investment is periodically evaluated for impairment. An impairment loss is recorded whenever there is a decline in value of an
investment below its carrying amount that is determined to be other than temporary.

Refer to Note 4 - Investments, for additional information.

Inventories—Inventories are stated at the lower of cost or net realizable value. We use a combination of standard cost and moving weighted-average
cost methodologies to determine the cost basis for our inventories, approximating a first-in, first-out basis. The standard cost of finished goods and work-in-
process inventory is composed of material, labor and manufacturing overhead, which approximates actual cost. In addition to stating inventory at the lower of
cost or net realizable value, we also evaluate inventory each reporting period for excess quantities and obsolescence, establishing reserves when necessary
based  upon  historical  experience,  assessment  of  economic  conditions  and  expected  demand.  Once  recorded,  these  reserves  are  considered  permanent
adjustments to the carrying value of inventory.

Property and Equipment—Property and equipment is stated at cost, less accumulated depreciation and amortization. Expenditures for maintenance and
repairs are charged to expense as incurred, whereas major improvements that significantly extend the useful life of the assets are capitalized as additions to
property and equipment.

Property and equipment are depreciated or amortized using the straight-line method over the following estimated useful lives:

Asset Classification
Buildings and improvements
Computer equipment and software
Furniture and fixtures
Finance lease assets and leasehold improvements
Machinery and equipment

Estimated Useful Life
(In Years)
20 - 40
2 - 5
7 - 10
Shorter of useful life or term of lease
2 - 7

Goodwill  and  Indefinite-Lived  Intangible  Assets—We  have  goodwill  and  certain  intangible  assets  with  indefinite  lives  which  are  not  subject  to
amortization.  These  are  reviewed  for  impairment  annually  as  of  the  end  of  our  fiscal  August  month  end  and  more  frequently  if  events  or  changes  in
circumstances indicate that the assets may be impaired. For our assessment of goodwill impairment, we compare the fair value to the carrying value of the
reporting unit. For our assessment of indefinite-lived assets we compare the carrying value of the asset to the estimated fair value of the asset. If impairment
exists, a loss is recorded to write down the value of the assets to their fair values. We performed our annual impairment tests of our goodwill and indefinite-
lived intangible assets and the results of these tests indicated that our goodwill and indefinite-lived intangible assets were not impaired as of August 27, 2021
or August 28, 2020.

Long-Lived  Asset  Valuation  and  Impairment  Assessment—Long-lived  assets  include  property  and  equipment  and  definite-lived  intangible  assets
subject to amortization. We evaluate long-lived assets for recoverability when events or changes in circumstances indicate that their carrying amounts may not
be recoverable. Circumstances which could trigger a review include, but are not limited to, significant decreases in the market price of the asset or asset group,
significant adverse changes in the business climate or legal factors, the accumulation of costs significantly in excess of the amount originally expected for the
acquisition  or  construction  of  the  asset,  current  period  cash  flow  or  operating  losses  combined  with  a  history  of  losses  or  a  forecast  of  continuing  losses
associated with the use of the asset and a current expectation that the asset will more likely than not, be sold or disposed of significantly before the end of its
previously estimated useful life.

In evaluating a long-lived asset for recoverability, we estimate the undiscounted cash flows expected to result from our use and eventual disposition of
the asset. If the sum of the expected undiscounted cash flows is less than the carrying amount of the asset group, an impairment loss, equal to the excess of the
carrying amount over the fair value of the asset, is recognized. In fiscal year 2019 we recorded impairment charges, see Note 10 - Impairments,  for  further
detail.

Other  Intangible  Assets—Our  other  intangible  assets,  including  acquired  technology  and  customer  relationships,  are  definite-lived  assets  and  are
subject to amortization. We amortize definite-lived assets over their estimated useful lives, which range from five to fourteen years, generally based on the
pattern over which we expect to receive the economic benefit from these assets.

Leases—We  have  operating  leases  for  certain  facilities,  as  well  as  manufacturing  and  office  equipment.  We  have  financing  leases  for  our  corporate

headquarters, including our fabrication facility, and to a lesser extent, various manufacturing equipment.

46

 
These leases expire at various dates through 2038, and certain of these leases have renewal options with the longest ranging up to two ten-year periods.

We determine that a contract contains a lease at lease inception if the contract conveys the right to control the use of an identified asset for a period of
time in exchange for consideration. In evaluating whether the right to control an identified asset exists, we assess whether we have the right to direct the use of
the identified asset and obtain substantially all of the economic benefit from the use of the identified asset. Leases with a term greater than one year are
recognized on the balance sheet as right-of-use (“ROU”) assets and lease liabilities. For leases with a term of one year or less, categorized as short-term leases,
we elected not to recognize the lease liability for these arrangements and the lease payments are recognized in the Consolidated Statements of Operations on a
straight-line basis over the lease term. ROU assets and lease liabilities are recognized at the present value of future minimum lease payments over the lease
term on the commencement date. ROU assets are initially measured as the amount of the initial lease liability, adjusted for initial direct costs, lease payments
made at or before the commencement date, and reduced by lease incentives received. We include options to renew or terminate when determining the lease
term when it is reasonably certain that the option will be exercised. Our lease agreements do not contain any material residual value guarantees or restrictive
covenants.

Our leases may contain lease and non-lease components. We elected to account for lease and non-lease components in a contract as part of a single lease

component. Fixed payments are considered part of the single lease component and included in the ROU assets and lease liabilities. Additionally, lease
contracts typically include variable payments and other costs that do not transfer a separate good or service, such as reimbursement for real estate taxes and
insurance, which are expensed as incurred.

Our leases generally do not provide an implicit interest rate. As a result, we utilize our incremental borrowing rates, which are the rates incurred to

borrow on a collateralized basis over a similar term and amount equal to the lease payments in a similar economic environment.

Revenue Recognition—Substantially  all  of  our  revenue  is  derived  from  sales  of  high-performance  RF,  microwave,  millimeter  wave  and  lightwave

semiconductor solutions into three primary markets: Telecom, I&D and Data Center.

We recognize revenue within the scope of ASC 606, Revenue from Contracts with Customers. Revenue is recognized when a customer obtains control of
products or services in an amount that reflects the consideration which we expect to receive in exchange for those goods or services. To determine revenue
recognition for arrangements within the scope of ASC 606, we perform the following five steps: (1) identify the contract(s) with a customer; (2) identify the
performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract;
and (5) recognize revenue when (or as) we satisfy performance obligations. Sales, value add and other taxes collected on behalf of third parties are excluded
from revenue. Our revenue arrangements do not contain significant financing components.

Contracts  with  our  customers  principally  contain  only  one  distinct  performance  obligation,  which  is  the  sale  of  products.  However,  due  to  multiple
products  potentially  being  sold  on  a  single  order,  we  are  required  to  allocate  consideration  based  on  the  estimated  relative  standalone  selling  prices  of  the
promised products.

Periodically, we enter into non-product development and license contracts with certain customers. We generally recognize revenue from these contracts
over-time  as  services  are  provided  based  on  the  terms  of  the  contract.  Non-product  development  and  license  revenue  is  not  significant  to  our  Revenue  or
Consolidated Statements of Operations for the periods presented. Revenue is deferred for amounts billed or received prior to delivery of the services. Certain
contracts  may  contain  multiple  performance  obligations  for  which  we  allocate  revenue  to  each  performance  obligation  based  on  the  relative  stand-alone
selling price.

Our  product  revenue  is  recognized  when  the  customer  obtains  control  of  the  product,  which  generally  occurs  at  a  point  in  time,  and  is  based  on  the
contractual shipping terms of a contract. Non-product revenue is generally recognized over time. For each contract, the promise to transfer the control of the
products or services, each of which is individually distinct, is considered to be the identified performance obligation. We provide an assurance type warranty
which is not sold separately and does not represent a separate performance obligation. Therefore, we account for such warranties under ASC 460, Guarantees,
and the estimated costs of warranty claims are generally accrued as cost of revenue in the period the related revenue is recorded.

We  have  agreements  with  certain  distribution  customers  which  may  include  certain  rights  of  return  and  pricing  programs,  including  returns  for  aged
inventory, stock rotation and price protection which affect the transaction price. Sales to these customers and programs offered are in accordance with terms
set  forth  in  written  agreements,  which  require  us  to  assess  the  potential  revenue  effects  of  this  variable  consideration  utilizing  the  expected  value  method.
Variable consideration is included in the transaction price if, in our judgment, it is probable that a significant future reversal of cumulative revenue under the
contract  will  not  occur.  As  such,  revenue  on  sales  to  customers  that  include  rights  of  return  and  pricing  programs  are  recorded  net  of  estimated  variable
consideration, utilizing the expected value method based on historical sales data. We believe that the judgments and estimates we utilize are reasonable based
upon current facts and circumstances, however utilizing different judgments and estimates could result in different amounts.

Practical  Expedients  and  Elections—ASC  606  requires  that  we  disclose  the  aggregate  amount  of  transaction  price  that  is  allocated  to  performance
obligations that have not yet been satisfied as of the reporting periods presented. The guidance provides certain practical expedients that limit this requirement
and, therefore, we do not disclose the value of unsatisfied performance obligations for

47

(i) contracts with an original expected length of one year or less and (ii) contracts for which revenue is recognized at the amount to which we have the right to
invoice for services performed. We have elected not to disclose the aggregate amount of transaction prices associated with unsatisfied or partially unsatisfied
performance obligations for contracts where these criteria are met.

Our policy is to capitalize any incremental costs incurred to obtain a customer contract, only to the extent that the benefit associated with the costs is

expected to be longer than one year. Capitalizable contract costs were not significant as of October 1, 2021 and October 2, 2020.

We  account  for  shipping  and  handling  activities  related  to  contracts  with  customers  as  costs  to  fulfill  the  promise  to  transfer  the  associated  products.
When shipping and handling costs are incurred after a customer obtains control of the products, we have elected to account for these as costs to fulfill the
promise and not as a separate performance obligation. Shipping and handling costs associated with the distribution of products to customers are recorded in
costs of revenue generally when the related product is shipped to the customer.

Research and Development Costs—Costs incurred in the research and development of products are expensed as incurred.

Income Taxes—Deferred tax assets and liabilities are recognized based on temporary differences between the financial reporting and income tax bases
of assets and liabilities, using rates anticipated to be in effect when such temporary differences reverse. A valuation allowance against net deferred tax assets is
required if, based upon the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.

We provide reserves for potential payments of tax to various tax authorities related to uncertain tax positions and other issues. Reserves are based on a
determination of whether and how much of a tax benefit is taken by us in our tax filings or positions that are more likely than not to be realized following an
examination by taxing authorities. We recognize the financial statement benefit of an uncertain tax position only after considering the probability that a tax
authority would sustain the position in an examination. For tax positions meeting a “more-likely-than-not” threshold, the amount recognized in the financial
statements is the benefit expected to be realized upon settlement with the tax authority. For tax positions not meeting the threshold, no financial statement
benefit is recognized. Potential interest and penalties associated with such uncertain tax positions are recorded as a component of income tax expense.

Earnings Per Share—Basic net income (loss) per share is computed by dividing net income (loss) by the weighted-average number of common shares
outstanding during the period, excluding the dilutive effect of common stock equivalents. Diluted net income (loss) per share reflects the dilutive effect of
common stock equivalents, such as stock options, warrants, restricted stock units and convertible debt, using the treasury stock method.

Fair Value Measurements—Financial assets and liabilities are measured at fair value. Fair value is an exit price, representing the amount that would be
received from the sale of an asset or paid to transfer a liability at the measurement date under current market conditions in an orderly transaction between
market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in
pricing an asset or liability. As a basis for considering such assumptions, we group financial assets and liabilities in a three-tier fair value hierarchy, according
to the inputs used in measuring fair value as follows:

•

•

•

Level 1—observable inputs such as quoted prices in active markets for identical assets and liabilities;

Level 2—inputs other than quoted prices in active markets that are observable either directly or indirectly, such as quoted prices in active markets
for similar assets and liabilities, quoted prices for identical assets and liabilities in markets that are not active and model-based valuation techniques
for which significant assumptions are observable in active markets; and,

Level 3—unobservable inputs for which there is little or no market data, requiring us to develop our own assumptions for model-based valuation
techniques.

This  hierarchy  requires  us  to  use  observable  market  data,  when  available,  and  to  minimize  the  use  of  unobservable  inputs  when  determining  fair

value. We recognize transfers between levels of the fair value hierarchy at the end of the reporting period.

Money market funds are actively traded and consist of highly liquid investments with original maturities of 90 days or less. They are measured at their
fair value and classified as Level 1. Corporate and agency bonds and commercial paper are categorized as Level 2 assets except where sufficient quoted prices
exist in active markets, in which case such securities are categorized as Level 1 assets. These securities are valued using third-party pricing services. These
services may use, for example, model-based pricing methods that utilize observable market data as inputs. We generally use quoted prices for recent trading
activity  of  assets  with  similar  characteristics  to  the  debt  security  or  bond  being  valued.  The  securities  and  bonds  priced  using  such  methods  are  generally
classified as Level 2. Broker dealer bids or quotes on securities with similar characteristics may also be used. Our common stock warrants were classified as
Level 3 due to unobservable inputs. We used the Black-Scholes option-pricing model to estimate the fair value of our common stock warrants, inclusive of
assumptions for the risk-free interest rate, dividends, expected term and estimated volatility.

The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate fair value due to the short-

term nature of these assets and liabilities.

48

Share-Based Compensation—We  account  for  all  share-based  compensation  arrangements  using  the  fair  value  method.  We  recognize  compensation
expense using the straight-line method for service-based awards and the accelerated method for performance-based awards, and providing that the minimum
amount of compensation recorded is equal to the vested portion of the award. We record the expense in the Consolidated Statements of Operations in the same
manner in which the award recipients’ salary costs are classified. For restricted stock awards, we use the closing stock price on the date of grant to estimate the
fair value of the awards. We use the Black-Scholes option-pricing model to estimate the fair value of stock options with service and performance conditions,
inclusive  of  assumptions  for  risk-free  interest  rates,  dividends,  expected  terms  and  estimated  volatility.  We  use  the  Monte  Carlo  Simulation  analysis  to
estimate  the  fair  value  of  stock  options  and  awards  with  market  conditions,  inclusive  of  assumptions  for  risk  free  interest  rates,  expected  term,  expected
volatility  and  the  target  price.  We  derive  the  risk-free  interest  rate  assumption  from  the  U.S.  Treasury’s  rates  for  U.S.  Treasury  zero-coupon  bonds  with
maturities  similar  to  the  expected  term  of  the  award  being  valued.  We  base  the  assumed  dividend  yield  on  our  expectation  of  not  paying  dividends  in  the
foreseeable  future.  We  calculate  the  weighted-average  expected  term  of  the  options  using  historical  data.  In  addition,  we  calculate  our  estimated  volatility
using  our  historical  stock  price  volatility  data.  We  account  for  forfeitures  when  they  occur.  Share-based  awards  that  are  settled  in  cash  are  recorded  as
liabilities. The measurement of the liability and compensation cost for these awards is based on the fair value of the award as of each period end date, which is
equivalent to the closing price of a share of our common stock on the period end date multiplied by the number of units earned, and is recorded in operating
income over the award’s vesting period. Changes in our payment obligation prior to the settlement date of a stock-based award are recorded as compensation
expense in operating income in the period of the change. The final payment amount for such awards is established on the date of vesting.

Guarantees  and  Indemnification  Obligations—We  enter  into  agreements  in  the  ordinary  course  of  business  with,  among  others,  customers,
distributors and OEMs. Most of these agreements require us to indemnify the other party against third-party claims alleging that a Company product infringes
a patent and/or copyright. Certain agreements in which we grant limited licenses to Company intellectual property require us to indemnify the other party
against third-party claims alleging that the use of the licensed intellectual property infringes a third-party's intellectual property. Certain of these agreements
require us to indemnify the other party against certain claims relating to property damage, personal injury or the acts or omissions, its employees, agents or
representatives. In addition, from time to time, we have made certain guarantees in the form of warranties regarding the performance of Company products to
customers.

We have agreements with certain vendors, creditors, lessors and service providers pursuant to which we have agreed to indemnify the other party for

specified matters, such as acts and omissions, its employees, agents or representatives.

We have procurement or license agreements with respect to technology used in our products and agreements in which we obtain rights to a product from
an OEM. Under some of these agreements, we have agreed to indemnify the supplier for certain claims that may be brought against such party with respect to
our acts or omissions relating to the supplied products or technologies.

Our certificate of incorporation and agreements with certain of our directors and officers and certain of our subsidiaries’ directors and officers provide
them indemnification rights, to the extent legally permissible, against liabilities incurred by them in connection with legal actions in which they may become
involved by reason of their service as a director or officer. As a matter of practice, we maintain director and officer liability insurance coverage, including
coverage for directors and officers of acquired companies.

We  have  not  experienced  any  losses  related  to  these  indemnification  obligations  in  any  period  presented  and  no  claims  with  respect  thereto  were
outstanding as of October 1, 2021 and October 2, 2020. We do not expect significant claims related to these indemnification obligations and, consequently,
have concluded that the fair value of these obligations is negligible. No liabilities related to indemnification liabilities have been established.

Recent Accounting Pronouncements

Pronouncements Adopted in Fiscal Year 2021

On  the  first  day  of  fiscal  year  2021,  we  adopted  Accounting  Standards  Update  (“ASU”)  2016-13,  Financial  Instruments  -  Credit  Losses  (Topic  326):
Measurement of Credit Losses on Financial Instruments. This ASU introduces a new accounting model known as Credit Expected Credit Losses (“CECL”),
which requires earlier recognition of credit losses. The CECL model utilizes a lifetime expected credit loss measurement objective for the recognition of credit
losses for receivables at the time the financial asset is originated or acquired, replacing the current incurred loss methodology that delays recognition of credit
losses  until  a  probable  loss  has  been  incurred.  There  are  other  provisions  within  the  standard  affecting  how  impairments  of  other  financial  assets  may  be
recorded and presented, as well as expanded disclosures. There was no impact to our consolidated financial statements from the adoption of this guidance.

In  January  2017,  the  Financial  Accounting  Standards  Board  (the  “FASB”)  issued  ASU  2017-04,  Intangibles  -  Goodwill  and  Other  (Topic  350):
Simplifying  the  Test  for  Goodwill  Impairment.  ASU  2017-04  simplifies  the  subsequent  measurement  of  goodwill  by  eliminating  Step  2  from  the  goodwill
impairment test. Instead, a one-step quantitative impairment test calculates goodwill impairment as the excess of the carrying value of a reporting unit over its
fair value, up to the carrying value of the goodwill. This ASU should be applied on a prospective basis. We adopted this ASU in the first quarter of fiscal year
2021 and the adoption of this update did not have an impact on our consolidated financial statements and related disclosures.

49

Pronouncements for Adoption in Subsequent Periods

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial
Reporting, which provides optional expedients and exceptions to applying the guidance on contract modifications, hedge accounting, and other transactions, to
simplify the accounting for transitioning from the London Interbank Offered Rate, and other interbank offered rates expected to be discontinued, to alternative
reference  rates.  The  guidance  in  this  Update  was  effective  upon  its  issuance.  If  elected,  the  guidance  is  to  be  applied  prospectively  through  December  31,
2022. We are currently evaluating the effect the potential adoption of this ASU will have on our consolidated financial statements, including but not limited to
our Credit Agreement, as defined in Note 16, Debt.

In August 2020, the FASB issued ASU 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): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, which simplifies the
accounting  for  certain  financial  instruments  with  characteristics  of  liability  and  equity,  including  convertible  instruments  and  contracts  on  an  entity’s  own
equity. The standard reduces the number of models used to account for convertible instruments, removes certain settlement conditions that are required for
equity  contracts  to  qualify  for  the  derivative  scope  exception,  and  requires  the  if-converted  method  for  calculation  of  diluted  earnings  per  share  for  all
convertible  instruments.  The  standard  is  effective  for  public  companies  for  fiscal  years,  and  interim  periods  within  those  fiscal  years,  beginning  after
December 15, 2021. Early adoption is permitted, and we plan to adopt this amendment as of October 2, 2021, the first day of fiscal year 2022. We expect the
resulting impact will be to reclassify $72.2 million of the equity component of our 2026 Convertible Notes, as defined in Note 16 - Debt, from additional paid-
in capital to long-term debt, with the remaining $7.5 million to accumulated deficit. On a prospective basis, there will be a reduction of our reported effective
interest rate of 4.25% on our 2026 Convertible Notes to their stated 0.25% coupon rate. For additional information regarding our debt, refer to Note 16 - Debt.

Contract Balances

We record contract assets or contract liabilities depending on the timing of revenue recognition, billings and cash collections on a contract-by-contract
basis. Our contract liabilities primarily relate to deferred revenue, including advanced consideration received from customers for contracts prior to the transfer
of control to the customer, and therefore revenue is subsequently recognized upon delivery of products and services.

As of October 1, 2021, October 2, 2020 and September 27, 2019 our contract liabilities were $2.8 million, $9.9 million and $10.7 million, respectively.
During the fiscal years ended October 1, 2021 and October 2, 2020, we recognized net sales of $9.4 million and $1.9 million, respectively, that were included
in the contract liabilities balance at the beginning of the period. The decrease in contract liabilities during the fiscal year ended October 1, 2021 was primarily
related to recognition of license and non-product development revenue, partially offset by the deferral of revenue for invoiced products and services prior to
when certain of our customers obtained control of the product and or services.

50

As of October 1, 2021 and October 2, 2020, $0.9 million and $3.5 million of our contract liabilities were recorded as other long-term liabilities on our

Consolidated Balance Sheets, respectively, with the remainder recorded in Accrued liabilities.

Total investments

We  have  determined  that  the  gross  unrealized  losses  on  available  for  sale  securities  at  October  1,  2021  and  October  2,  2020  are  temporary  in  nature
and/or  do  not  relate  to  credit  loss,  therefore  there  is  no  expense  for  credit  losses  recorded  in  our  Consolidated  Statements  of  Operations.  We  review  our
investments to identify and evaluate investments that have indications of possible impairment due to credit loss. The techniques used to measure the fair value
of our investments are described in Note 2 - Summary of Significant Accounting Policies. Factors considered in determining whether a loss is due to credit loss
include the extent to which fair value has been less than the cost basis, adverse conditions, the financial condition and near-term prospects of the investee, and
our intent and ability to hold the investment for a period of time sufficient to allow for any anticipated recovery in market value. Substantially all of our fixed
income securities are rated investment grade.

During the fiscal years ended October 1, 2021, October 2, 2020 and September 27, 2019, we received proceeds from sales and maturities of available-
for-sale  securities  of  $209.3  million,  $183.9  million  and  $173.0  million,  respectively.  During  the  fiscal  years  ended  October  1,  2021,  October  2,  2020  and
September  27,  2019,  gross  realized  gains  were  $0.5  million,  $0.3  million  and  $0.2  million,  respectively.  During  the  fiscal  years  ended  October  1,  2021,
October 2, 2020 and September 27, 2019, gross realized losses were less than $0.1 million, $0.1 million and $0.2 million, respectively. Gross realized gains
and losses were recorded within other expense in each period presented.

Other  Investments  —  As  of  October  1,  2021  and  October  2,  2020,  we  held  two  non-marketable  equity  investments  classified  as  other  long-term
investments, which includes an investment in a Series B preferred stock ownership of a privately held manufacturing corporation with preferred liquidation
rights over other equity shares. As the equity securities do not have a readily determinable fair value and do not qualify for the practical expedient under ASC
820, Fair Value Measurement, we have elected to account for this investment at cost less any impairment. During the fiscal quarter ended October 2, 2020, we
identified  impairment  indicators  for  this  investment  and  recorded  an  impairment  charge  of  $2.5  million  to  Other  expense.  As  of  October  1,  2021  and
October 2, 2020, the carrying value of this investment was $2.5 million.

Also  included  in  long-term  investments,  is  a  non-controlling  investment  of  less  than  10%  of  the  outstanding  equity  of  a  private  company,  Ampere
Computing  Holdings  LLC  (“Ampere”),  that  was  acquired  in  conjunction  with  our  divestiture  of  the  Compute  business  during  our  fiscal  year  2018.  This
investment’s carrying value is updated quarterly based on our proportionate share of the

51

 
 
 
 
 
gains or losses, as well as any changes in Ampere's equity, utilizing the equity method. We are a passive investor with limited rights and are not engaged in the
operating  activities  of  Ampere.  One  of  Ampere’s  other  limited  liability  company  members  has  a  call  option  right  to  purchase  all  of  our  equity  during  the
period following October 27, 2021 and prior to 45 days thereafter, for a maximum fixed price of approximately $128.0 million which may not represent fair
market value. We have no control and cannot predict when or if this call option will be exercised, whether our equity position will become liquid or whether it
will become further diluted due to capital structure changes to Ampere. Any gain or loss from an exercise of a call option would be recognized at the time it is
realized.

During fiscal years 2021, 2020 and 2019, we recorded $2.4 million, $3.4 million and $7.5 million of non-cash net losses associated with this investment
as  other  expense  in  our  Consolidated  Statements  of  Operations.  The  net  loss  amounts  for  fiscal  years  2021,  2020  and  2019  include  non-cash  gains  of

During fiscal year 2019, we initiated a plan to strategically realign, streamline and improve our operations, including reducing our workforce and exiting
certain  product  offerings  and  research  and  development  facilities.  See  Note  12  -  Restructurings,  for  additional  information  about  the  2019  Plan.  These
activities led us to reassess our previous estimates for expected future revenue growth. We performed impairment analyses to determine whether our goodwill
and long-lived assets, comprised of definite-lived intangible assets and property and equipment, were recoverable. We performed a goodwill impairment test
for our consolidated reporting unit. We calculated the fair value of our reporting unit using market capitalization and compared its fair value to its carrying
amount,  including  goodwill.  The  fair  value  exceeded  the  carrying  amount,  therefore  we  determined  that  goodwill  of  the  reporting  unit  was  not  impaired.
Based on the estimated undiscounted cash flow assessment for long-lived assets, we determined that for an asset group, the cash flows were not sufficient to
recover the carrying value of the long-lived assets over their remaining useful lives. Accordingly, we recorded impairment charges of $217.5 million and $33.2
million to our customer relationship and technology intangible assets, respectively, in fiscal year 2019, based on the difference between the fair value and the
carrying  value  of  the  long-lived  assets.  We  will  continue  to  monitor  for  events  or  changes  in  business  circumstances  that  may  indicate  that  the  remaining
carrying value of the asset group may not be recoverable. We used the income approach to determine the fair value of the definite-lived intangible assets and
the cost approach to determine the fair value of our property and equipment.

Additionally,  in  connection  with  the  2019  Plan,  we  determined  that  certain  intangible  assets  were  abandoned  and  would  not  have  a  future  benefit.
Accordingly, we recorded impairment charges of $2.4 million and $3.9 million to our customer relationship and technology intangible assets, respectively,
during fiscal year 2019.

During  fiscal  year  2019,  we  also  abandoned  equipment  recorded  as  construction  in  process.  Accordingly,  we  recorded  impairment  charges  of  $7.8

million to reflect the estimated salvage value of the equipment.

Total impairment charges recorded to intangible assets and assets recorded as construction in process for fiscal year 2019 were $264.8 million.

See Note 12 - Restructurings for information related to property and equipment impaired as part of our restructuring actions.

2019 Plan

During  the  fiscal  quarter  ended  June  28,  2019,  we  committed  to  a  plan  to  strategically  realign,  streamline  and  improve  certain  of  our  business  and
operations,  including  reducing  our  workforce  by  approximately  250  employees  and  exiting  six  development  facilities  in  France,  Japan,  the  Netherlands,
Florida,  Massachusetts  and  Rhode  Island,  reducing  certain  development  activities  for  one  of  our  product  lines  and  no  longer  investing  in  the  design  and
development of optical modules and subsystems for Data Center applications (the “2019 Plan”). During the fiscal year ended October 2, 2020, we incurred
restructuring expenses of $1.2 million under the 2019 Plan, including $0.8 million of facility-related costs and $0.4 million of employee-related costs. We
incurred restructuring charges of $11.6 million in the fiscal year ended September 27, 2019, including $6.3 million of employee-related costs, $4.0 million of
impairment expense for fixed assets and $1.3 million of other facility-related costs. This action was completed during fiscal 2020 and we do not expect to
incur further costs. The remaining charges were paid during fiscal year 2021.

13. PRODUCT WARRANTIES

We  establish  a  product  warranty  liability  at  the  time  of  revenue  recognition.  Product  warranties  generally  have  terms  of  12  months  and  cover
nonconformance  with  specifications  and  defects  in  material  or  workmanship.  For  sales  to  distributors,  our  warranty  generally  begins  when  the  product  is
resold by the distributor. The liability is based on estimated costs to fulfill customer product warranty obligations and utilizes historical product failure rates.
Should actual warranty obligations differ from estimates, revisions to the warranty liability may be required.

We  established  a  defined  contribution  savings  plan  under  Section  401(k)  of  the  Internal  Revenue  Code  of  1986,  as  amended  on  October  1,  2009
(“401(k)  Plan”).  The  401(k)  Plan  follows  a  calendar  year,  covers  substantially  all  U.S.  employees  who  meet  minimum  age  and  service  requirements  and
allows participants to defer a portion of their annual compensation on a pretax basis, subject to legal limitations. Our contributions to the 401(k) Plan may be
made at the discretion of the board of directors. During the fiscal years ended October 1, 2021, October 2, 2020 and September 27, 2019, we contributed $2.3
million, $2.3 million and $2.6 million to our 401(k) Plan for calendar years 2020, 2019 and 2018, respectively.

Our  employees  located  in  foreign  jurisdictions  meeting  minimum  age  and  service  requirements  participate  in  defined  contribution  plans  whereby
participants  may  defer  a  portion  of  their  annual  compensation  on  a  pretax  basis,  subject  to  legal  limitations.  Company  contributions  to  these  plans  are
discretionary and vary per region. We expensed contributions of $1.3 million, $1.0 million and $1.1 million for fiscal years 2021, 2020 and 2019, respectively.

15. COMMITMENTS AND CONTINGENCIES

Asset Retirement Obligations—We are obligated under certain facility leases to restore those facilities to the condition in which we or our predecessors
first occupied the facilities. We are required to remove leasehold improvements and equipment installed in these facilities prior to termination of the leases. As
of the end of fiscal years 2021 and 2020, the estimated costs for the removal of these assets are recorded as asset retirement obligations in other long-term
liabilities were $1.9 million and $1.9 million, respectively.

Purchase Commitments—As of October 1, 2021, we had outstanding non-cancelable purchase commitments of $82.7 million primarily for purchases
of  services  and  inventory  supply  arrangements. In  addition,  we  have  $27.2  million  in  fixed  payments  associated  with  a  power  purchase  agreement  that  is
expected to commence in fiscal 2022 and has a 15-year term. See Note 17- Financing Obligation for additional detail on the power purchase agreement.

Litigation—From time to time we may be subject to commercial disputes, employment issues, claims by other companies in the industry that we have
infringed  their  intellectual  property  rights  and  other  similar  claims  and  litigation.  Any  such  claims  may  lead  to  future  litigation  and  material  damages  and
defense costs. We were not involved in any material pending legal proceedings during the year ended October 1, 2021.

As  of  October  1,  2021,  we  are  party  to  a  credit  agreement  dated  as  of  May  8,  2014  with  a  syndicate  of  lenders  and  Goldman  Sachs  Bank  USA,  as
administrative  agent  (as  amended  on  February  13,  2015,  August  31,  2016,  March  10,  2017,  May  19,  2017,  May  2,  2018  and  May  9,  2018,  the  “Credit
Agreement”).

The Credit Agreement consists of term loans with an original principal amount of $700.0 million (“Term Loans”) and a revolving credit facility with an
aggregate, undrawn borrowing capacity of $160.0 million (“Revolving Facility”). The Revolving Facility expired on November 8, 2021 and the Term Loans
will mature in May 2024 and bear interest at: (i) for LIBOR loans for any interest period, a rate per annum equal to the LIBOR rate as determined by the
administrative agent, plus an applicable margin of 2.25%; and (ii) for base rate loans, a rate per annum equal to the greater of (a) the prime rate quoted in the
print edition of the Wall Street Journal, Money Rates Section, (b) the federal funds rate plus one-half of 1.00% and (c) the LIBOR rate applicable to a one-
month interest period plus 1.00% (but, in each case, not less than 1.00%), plus an applicable margin of 1.25%.

During fiscal year 2021, we repaid $543.6 million in principal under the Term Loans using $443.6 million of the net proceeds from our 2026 Convertible
Notes  offering,  described  below,  as  well  as  existing  cash  and  short-term  investments.  In  connection  with  these  prepayments,  during  fiscal  year  2021,  we
expensed  unamortized  deferred  financing  costs  and  recognized  losses  on  extinguishment  of  debt  of  $4.4  million  within  the  Other  expense,  net  line  in  our
Consolidated  Statements  of  Operations.  The  loss  on  extinguishment  is  a  non-cash  adjustment  to  cash  flows  from  operating  activities  in  our  Consolidated
Statements of Cash Flows for the fiscal year 2021.

As  of  October  1,  2021,  there  are  no  minimum  principal  repayments  on  the  Term  Loans  until  2024  when  the  remaining  principal  balance  of
$120.8 million becomes due. The fair value of the Term Loans was estimated to be approximately $120.2 million as of October 1, 2021 and was determined
using Level 2 inputs, including a quoted price from a financial institution.

As of October 1, 2021, approximately $1.0 million of deferred financing costs remain unamortized, of which $0.9 million is related to the Term Loans
and is recorded as a direct reduction of the recognized debt liabilities in our accompanying Consolidated Balance Sheet, and less than $0.1 million is related to
the Revolving Facility and is recorded in other long-term assets in our accompanying Consolidated Balance Sheet.

The Term Loans and Revolving Facility are secured by a first priority lien on substantially all of our assets and provide that we must comply with certain

financial and non-financial covenants.

2026 Convertible Notes

On March 25, 2021, we issued 0.25% convertible senior notes due in 2026, pursuant to an indenture dated as of such date (the “Indenture”), between the
Company and U.S. Bank National Association, as trustee, with an aggregate principal amount of $400.0 million (the “Initial Notes”), and on April 6, 2021, we
issued  an  additional  $50.0  million  aggregate  principal  amount  (the  “Additional  Notes”)  (together,  the  “2026  Convertible  Notes”).  No  additional  2026
Convertible Notes will be issued and the aggregate principal balance is $450.0 million. The 2026 Convertible Notes will mature on March 15, 2026, unless
earlier converted, redeemed or repurchased.

The Additional Notes were issued and sold to the initial purchaser of the Initial Notes, pursuant to the option to purchase the Additional Notes granted by

the Company to the initial purchaser and have the same terms as the Initial Notes.

Holders of the 2026 Convertible Notes may convert their notes at their option at any time prior to the close of business on the business day immediately

preceding December 15, 2025 in multiples of $1,000 principal amount, only under the following

59

circumstances:  (i)  during  any  fiscal  quarter  commencing  after  the  fiscal  quarter  ending  on  July  2,  2021  (and  only  during  such  fiscal  quarter),  if  the  last
reported sale price of our common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the
last trading day of the immediately preceding fiscal quarter is greater than or equal to 130% of the conversion price for the notes on each applicable trading
day; (ii) during the five business day period after any five consecutive trading day period (the “Measurement Period”) in which the “trading price” (as defined
in  the  Indenture)  per  $1,000  principal  amount  of  the  notes  for  each  trading  day  of  the  Measurement  Period  was  less  than  98%  of  the  product  of  the  last
reported sale price of our common stock and the conversion rate for the notes on each such trading day; (iii) if we call such notes for redemption, at any time
prior  to  the  close  of  business  on  the  second  scheduled  trading  day  immediately  preceding  the  applicable  redemption  date;  or  (iv)  upon  the  occurrence  of
specified  corporate  events  described  in  the  Indenture.  On  or  after  December  15,  2025  until  the  close  of  business  on  the  second  scheduled  trading  day
immediately preceding the maturity date, holders may convert their notes in multiples of $1,000 principal amount, regardless of the foregoing circumstances.

The initial conversion rate for the 2026 Convertible Notes is 12.1767 shares of common stock per $1,000 principal amount of the notes, equivalent to an
initial conversion price of approximately $82.12 per share of common stock. The conversion rate will be subject to adjustment upon the occurrence of certain
specified events in the Indenture.

Upon  conversion  of  the  2026  Convertible  Notes,  we  had  the  option  to  pay  or  deliver,  as  the  case  may  be,  cash,  shares  of  our  common  stock  or  a
combination  of  cash  and  shares  of  our  common  stock,  at  our  election  (subject  to,  and  in  accordance  with,  the  settlement  provisions  of  the  Indenture).  In
November 2021, we made an irrevocable election to pay cash up to the aggregate principal amount of the notes to be converted and pay or deliver, as the case
may be, cash, shares of our common stock or a combination of cash and shares of our common stock, at our election, in respect of the remainder, if any, of our
conversion obligation in excess of the aggregate principal amount of the notes being converted (subject to, and in accordance with, the settlement provisions
of the Indenture). We may not redeem the notes prior to March 20, 2024. We may redeem for cash all or any portion of the notes, at our option, on or after
March 20, 2024 if the last reported sale price per share of our common stock has been at least 130% of the conversion price then in effect for at least 20
trading days (whether or not consecutive), including the trading day immediately preceding the date on which we provide notice of redemption, during any 30
consecutive  trading  day  period  ending  on,  and  including,  the  trading  day  immediately  preceding  the  date  on  which  we  provide  notice  of  redemption,  at  a
redemption price equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest, to, but not including, the redemption
date.

The  Indenture  does  not  contain  any  financial  or  operating  covenants  or  restrictions  on  the  payments  of  dividends,  the  making  of  investments,  the

incurrence of indebtedness or the purchase or prepayment of securities by us or any of our subsidiaries.

The proceeds from the issuance of the 2026 Convertible Notes have been allocated between the conversion feature recorded as equity and the liability for
the notes themselves. The carrying amount of the liability component was calculated by measuring the fair value of a similar debt instrument that does not
have an associated convertible feature. The carrying amount of the equity component representing the conversion option was determined by deducting the fair
value of the liability component from the par value of the 2026 Convertible Notes. The difference of $80.7 million between the principal amount of the 2026
Convertible Notes and the liability component (the “Debt Discount”) is amortized to interest expense using the effective interest method over the term of the
2026 Convertible Notes. The equity component of the 2026 Convertible Notes is included in additional paid-in capital in the consolidated balance sheet and is
not remeasured as long as it continues to meet the conditions for equity classification.

In accounting for the transaction costs related to the 2026 Convertible Notes, we allocated the total amount incurred of approximately $5.7 million to the
liability and equity components of the 2026 Convertible Notes based on the proportion of the proceeds allocated to the debt and equity components. Issuance
costs attributable to the liability component were approximately $4.7 million, were recorded as additional Debt Discount and are amortized to interest expense
over  the  contractual  terms  of  the  2026  Convertible  Notes.  Issuance  costs  attributable  to  the  equity  component  were  approximately  $1.0  million  and  are
recorded as a reduction of additional paid in capital in stockholders’ equity.

For fiscal year 2021, accretion of the Debt Discount included in interest expense was $7.6 million, and as of October 1, 2021, the unamortized discount on

the 2026 Convertible Notes was $73.1 million. For fiscal year 2021, total interest expense for the 2026 Convertible Notes was $8.2 million.

The fair value of our 2026 Convertible Notes, including the conversion feature, was $479.4 million as of October 1, 2021 and was determined based on

quoted prices in markets that are not active, which is considered a Level 2 valuation input.

There are no future minimum principal payments under the notes as of October 1, 2021; the full amount of $450.0 million is due in fiscal 2026.

17. FINANCING OBLIGATION

On July 17, 2020, we entered into a power purchase agreement, which includes installation of electric power and thermal energy producing systems at
our fabrication facility in Lowell, Massachusetts. This system is expected to reduce our consumption of energy while delivering sustainable, resilient energy
for  heating  and  cooling.  Despite  not  being  the  legal  owner  of  these  systems,  for  accounting  purposes  only  we  are  deemed  to  be  the  owner  of  the  power
generator during construction since we control the use of the asset. As of October 1, 2021, we capitalized $8.9 million of construction in process to Property
and equipment, net and recorded a corresponding liability of $8.9 million primarily to Financing obligation on our consolidated balance sheet. The financing
obligation was calculated based on future fixed payments allocated to the power generator of $16.8 million over the 15-year term, discounted at an implied
discount rate of 7.7%, and the remaining future minimum payments are for power purchases. In total, we have $27.2 million in fixed payments associated with
the power purchase agreement which is expected to commence in fiscal 2022 and has a 15-year term.

We have authorized 10 million shares of $0.001 par value preferred stock and 300 million shares of $0.001 par value common stock as of October 1,
2021  and  October  2,  2020.  The  outstanding  shares  of  common  stock  as  of  October  1,  2021  presented  in  the  accompanying  Consolidated  Statements  of
Stockholders’ Equity, excludes 2,093 unvested shares of restricted stock awards, issued as compensation to employees that were subject to forfeiture. There
were 5,414 unvested shares of restricted stock awards that were subject to forfeiture as of October 2, 2020.

Common Stock Warrants—In March 2012, we issued warrants to purchase 1,281,358 shares of common stock for $14.05 per share. During November

2020, Summit Partners Private Equity Fund VII-A, L.P., Summit Partners Private Equity Fund VII-B, L.P.,

62

Summit Investors I, LLC, Summit Investors I (UK), L.P. and Mainsail Partners II, L.P. made cashless exercises of warrants for 1,281,358 shares at an exercise
price of $14.05 per share, resulting in the issuance of 857,631 shares of common stock.

Through the date of exercise, we recorded the estimated fair values of the warrants as a long-term liability in the accompanying Consolidated Balance
Sheets  with  changes  in  the  estimated  fair  value  being  recorded  in  the  accompanying  Consolidated  Statements  of  Operations.  As  of  October  1,  2021,  no
warrants remain outstanding.

20. SHARE-BASED COMPENSATION PLANS

Stock Plans

We have five equity incentive plans: the Amended and Restated 2009 Omnibus Stock Plan (“2009 Plan”), the 2012 Omnibus Incentive Plan, as amended
(“2012 Plan”), the 2021 Omnibus Incentive Plan (“2021 Plan”), the 2012 Employee Stock Purchase Plan, as amended and restated (“2012 ESPP”) and the
2021 Employee Stock Purchase Plan (“2021 ESPP”).

Upon the closing of our initial public offering, all shares that were reserved under the 2009 Plan but not awarded were assumed by the 2012 Plan. No
additional awards will be made under the 2009 Plan. The 2021 Plan replaced the 2012 Plan and, following the adoption of the 2021 Plan on March 4, 2021, no
additional awards have been or will be made under the 2012 Plan. We have outstanding awards under the 2021 Plan, as well as the 2012 Plan. Under the 2021
Plan, we have the ability to issue incentive stock options (“ISOs”), non-statutory stock options (“NSOs”), stock appreciation rights (“SARS”), restricted stock
awards (“RSAs”), unrestricted stock awards, stock units (including restricted stock units (“RSUs”) and performance-based restricted stock units (“PRSUs”)),
performance awards, cash awards, and other share-based awards to employees, directors, consultants and advisors. The ISOs and NSOs must be granted at an
exercise price, and the SARS must be granted at a base value, per share of not less than 100% of the closing price of a share of our common stock on the date
of grant (or, if no closing price is reported on that date, the closing price on the immediately preceding date on which a closing price was reported) (110% in
the case of certain ISOs). Options granted primarily vest based on certain market-based and performance-based criteria as described below and generally have
a term of four to seven years. Certain of the share-based awards granted and outstanding as of October 1, 2021, are subject to accelerated vesting upon a sale
of the Company or similar changes in control.

As of October 1, 2021, we had 5.9 million shares available for future issuance under the 2021 Plan and 1.5 million shares available for issuance under

our 2021 ESPP.

Incentive Stock Units

Outside of the five equity plans described above, we also grant incentive stock units (“ISUs”) to certain of our international employees which typically
vest  over  four  years  and  for  which  the  fair  value  is  determined  by  our  underlying  stock  price,  which  are  classified  as  liabilities  and  settled  in  cash  upon
vesting.

As of October 1, 2021 and October 2, 2020, the fair value of outstanding awards was $8.9 million and $7.6 million, respectively, and the associated
accrued  compensation  liability  was  $6.2  million  and  $4.6  million,  respectively.  During  fiscal  years  2021,  2020  and  2019,  76,894,  62,344  and  69,035  ISU
awards vested, respectively, and were paid at a fair value of $4.2 million, $1.9 million and $1.2 million, respectively.

During  fiscal  years  2021,  2020  and  2019,  we  recorded  an  expense  for  these  ISU  awards  of  $5.8  million,  $4.4  million  and  $1.3  million,  respectively.

These expenses are not included in the share-based compensation expense totals below.

Employee Stock Purchase Plan

The  2021  ESPP  allows  eligible  employees  to  purchase  shares  of  our  common  stock  at  a  discount  through  payroll  deductions  of  up  to  15%  of  their
eligible compensation, subject to any plan limitations. In administering the 2021 ESPP, the board of directors has limited discretion to set the length of the
offering periods thereunder. As of October 1, 2021, no purchases have been made under the 2021 ESPP Plan. In fiscal years 2021, 2020 and 2019, 166,275,
272,469 and 421,777 shares of common stock were issued under the 2012 ESPP, respectively.

The total fair value of restricted stock awards and units vested was $64.1 million, $19.1 million and $11.7 million for the fiscal years 2021, 2020 and

2019, respectively. RSUs granted generally vest over a period of three or four years.

In addition to RSUs, we also issue PRSUs with specific performance vesting criteria. These PRSUs have both a service and performance-based vesting
condition  and  awards  are  typically  divided  into  three  equal  tranches  and  vest  based  on  achieving  certain  adjusted  earnings  per  share  growth  metrics.  The
service condition requires participants to be employed in November following the performance period in which the performance condition was met, when the
Company's  annual  financial  performance  is  announced  to  the  financial  markets.  Depending  on  the  actual  performance  achieved,  a  participant  may  earn
between 0% to 300% of the targeted shares for each tranche, which is determined based on a straight-line interpolation applied for the achievement between
the specified performance ranges. During fiscal year 2021, the performance condition for 143,485 target shares were earned at 300%, and therefore 430,455
shares  with  a  total  grant  date  fair  value  of  $7.7  million  vested  in  November  2020  when  the  service  condition  was  achieved.  During  fiscal  year  2021,  we
granted 94,832 PRSUs and 10,644 were forfeited. The amount of incremental PRSU awards that could ultimately vest if all performance criteria are achieved
would be 1,197,675 shares assuming a maximum of 300% of the targeted shares.

64

We granted 200,000 market-based PRSUs during fiscal year 2019, at a weighted average grant date fair value of $17.65 per share, and a total fair value of

$3.5 million. Recipients may earn between 0% and 150% of the target number of shares based on the Company's achievement of total stockholder return in
comparison to a peer group of companies in the Nasdaq composite index over a period of approximately three years. The fair value of the awards was
estimated using a Monte Carlo simulation and compensation expense is recognized ratably over the service period based on the grant date fair value of the
awards of $3.5 million subject to the market condition. The expected volatility of the Company's common stock was estimated based on the historical average
volatility rate over the three-year period. The dividend yield assumption was based on historical and anticipated dividend payouts. The risk-free rate
assumption was based on observed interest rates consistent with the three-year measurement period. The assumptions used to value the awards are as follows:

Risk free interest rate
Years to maturity
Expected volatility rate
Dividend yield

respectively.

Stock Options with Market-based Vesting Criteria

We grant NSOs that are subject to vesting only upon the market price of our underlying public stock closing above a certain price target within seven
years of the date of grant. Share-based compensation expense is recognized regardless of the number of awards that are earned based on the market condition
and is recognized on a straight-line basis over the estimated service period of approximately three years. If the required service period is not met for these
options,  then  the  share-based  compensation  expense  would  be  reversed.  As  of  October  1,  2021,  all  stock  options  with  market-based  vesting  criteria  have
vested and no unrecognized compensation cost remains to be recognized.

There  were  no  stock  options  with  market-based  vesting  criteria  granted  for  fiscal  years  2021  and  2020,  respectively.  Stock  options  with  market-based
vesting criteria granted for fiscal year 2019 was 585,000 at weighted average grant date fair value of $7.47 per share, or total grant date fair value of $2.4
million.

65

These  NSOs  with  market-based  vesting  criteria  were  valued  using  a  Monte  Carlo  simulation  model.  The  weighted  average  Monte  Carlo  input

During our fiscal first quarter of 2019, we canceled 1,122,500 performance-based stock options with a concurrent grant of 748,328 PRSUs for 13 then
current employees, which was accounted for as a modification. The incremental compensation cost resulting from the modification was $8.2 million and was
being recognized as share-based compensation expense over the requisite service period of three years for the new PRSU awards. As a result of subsequent
actions that resulted in forfeitures, the remaining compensation expense associated with this modification as of October 1, 2021 was $0.1 million.

21. INCOME TAXES

Deferred  income  taxes  reflect  the  net  effect  of  temporary  differences  between  the  carrying  amounts  of  assets  and  liabilities  for  financial  reporting

purposes and amounts used for income tax purposes. The components of our deferred tax assets and liabilities are as follows (in thousands):

Deferred tax assets:

Net operating loss and credit carryforward

  Intangible assets

Accrued expenses
Lease obligations
Minority equity investments

  Property and equipment

Interest

Gross deferred tax asset
  Less valuation allowance

Deferred tax asset, net of valuation allowance

As of October 1, 2021 and October 2, 2020, our Consolidated Balance Sheets included $39.5 million and $41.9 million, respectively, of deferred income

taxes recorded as long-term assets and $2.2 million and $2.1 million, respectively, of deferred income taxes recorded in Other long-term liabilities.

As of October 1, 2021, we had $855.8 million of gross federal net operating loss (“NOL”) carryforwards, primarily related to acquisitions made in prior
fiscal years. The federal NOL carryforwards will expire at various dates through 2038 for losses generated prior to the tax period ended September 27, 2019.
For losses generated during the tax period ended September 27, 2019 and future years, the NOL carryforward period is indefinite. The reported net operating
loss  carryforward  includes  any  limitation  under  Sections  382  and  383  of  the  Internal  Revenue  Code  of  1986,  as  amended,  which  applies  to  an  ownership
change as defined under Section 382.

We recognize deferred tax assets to the extent that we believe that these assets are more likely than not to be realized. In making this determination, we
consider available positive and negative evidence and factors that may impact the valuation of our deferred tax asset including results of recent operations,
future reversals of existing taxable temporary differences, projected future taxable income, and tax-planning strategies. We have significant negative objective
evidence in the form of adjusted cumulative losses in the U.S. over the three-year period ended October 1, 2021 that resulted in our continued determination
that there was not sufficient objectively verifiable positive evidence to offset this negative objective evidence and we concluded that a full valuation allowance
was still appropriate for our U.S. deferred tax assets.

The $250.3 million of valuation allowance as of October 1, 2021 relates primarily to federal and state NOLs, tax credit carryforwards and a partial
valuation allowance on tax credits in Canada of $7.1 million whose recovery is not considered more likely than not. The $277.4 million of valuation allowance
as of October 2, 2020 related primarily to federal and state NOLs, tax credit carryforwards and a partial valuation allowance on tax credits in Canada of $8.0
million, for which recovery is not considered likely. The change during the fiscal year ended October 1, 2021 of $27.1 million primarily relates to the initial
recognition of a deferred tax liability relating to our newly issued convertible debt which is offset by a reduction in our valuation allowance, and a reduction in
our net NOL and credit carryforwards.

For fiscal years 2021, 2020 and 2019, the effective tax rates on $42.9 million, $(41.6) million and $(423.2) million, respectively, of pre-tax income (loss)

from continuing operations were 11.6%, (10.9)% and 9.3%, respectively. The effective income tax rates for fiscal years 2021, 2020 and 2019 were impacted
by a lower income tax rate in many foreign jurisdictions in which our foreign subsidiaries operate, changes in valuation allowance, research and development
tax credits, a fair market value adjustment of our warrant liability and the inclusion of Global Intangible Low Taxed Income. For fiscal year 2020, the effective
tax rate was also impacted by an adjustment in our Section 382 limitation which increased our California NOL carryforwards. For fiscal year 2019, the
effective tax rate was impacted by a change in our NOL carryforward due to an adjustment in our Section 382 limitation from a prior period acquisition and
was also impacted by the immediate recognition of the current and deferred income tax effects totaling $39.8 million from an intra-entity transfer of a license
for intellectual property to a higher taxed jurisdiction that received a tax basis step-up.

On  March  27,  2020,  the  U.S.  Congress  enacted  the  Coronavirus  Aid  Relief  &  Economic  Security  Act  (“CARES  Act”).  The  CARES  Act  made  a
technical correction to the Tax Act impacting the Company’s NOL carryforward for the fiscal year ending September 29, 2018 by limiting it to a 20-year
carryforward  period,  rather  than  having  an  indefinite  life  carryforward  without  the  80%  limitation.  This  technical  correction  resulted  in  the  Company
increasing its indefinite lived deferred tax liability by $1.4 million during fiscal year 2020, with an offsetting adjustment to tax expense.

The liability for unrecognized tax benefits was zero as of October 1, 2021 and $0.3 million as of October 2, 2020 and September 27, 2019. During the
fiscal year ending October 1, 2021, we reported a reduction of $0.3 million in unrecognized tax benefits due to closure of the related audit periods. The full
reduction in unrecognized tax benefits reduced our income tax expense.

carryforwards from those years.

22. RELATED-PARTY TRANSACTIONS

During fiscal year 2020, we sold $0.4 million of commercial products to Mission Microwave Technologies, LLC (“Mission”), a MACOM customer and
an  affiliate  of  directors  John  and  Susan  Ocampo.  Together,  Mr.  and  Mrs.  Ocampo  are  MACOM's  largest  stockholders.  Stephen  G.  Daly,  the  Company's
President and Chief Executive Officer, has an equity interest of less than 1% in Mission.

As  of  October  2,  2020,  we  had  warrants  outstanding  which  were  measured  at  fair  value.  During  fiscal  year  2019  we  recorded  gains  of  $0.8  million
associated with adjusting the fair value of the warrants, in the Consolidated Statements of Operations primarily as a result of declines in our stock price. When
calculating earnings per share we are required to adjust for the dilutive effect of outstanding common stock equivalents, including adjustment to the numerator
for the dilutive effect of contracts that must be settled in common stock. During fiscal years 2021, 2020 and 2019, we excluded the effects of the warrant and
the respective 87,494, 639,133 and 214,303 potential shares of common stock issuable upon exercise of warrants as the inclusion would be anti-dilutive. The
table excludes the effects of 87,494, 1,755,973, and 386,552 shares for fiscal years 2021, 2020 and 2019, respectively, of potential shares of common stock
issuable  upon  exercise  of  stock  options,  restricted  stock,  restricted  stock  units  and  warrants  as  the  inclusion  would  be  anti-dilutive.  The  2026  Convertible
Notes do not have an impact on diluted earnings per share for fiscal year 2021.

We  have  one  reportable  operating  segment  that  designs,  develops,  manufactures  and  markets  semiconductors  and  modules.  The  determination  of
reportable operating segments is based on the chief operating decision maker’s (“CODM”) use of financial information provided for the purposes of assessing
performance and making operating decisions. The Company's CODM is its President and Chief Executive Officer. In evaluating financial performance and
making operating decisions, the CODM primarily uses consolidated metrics. The Company assesses its determination of operating segments at least annually.
We continue to evaluate our internal reporting structure and the potential impact of any changes on our segment reporting.

ITEM 9A. CONTROLS AND PROCEDURES.

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange
Act”), that are intended to ensure that information that would be required to be disclosed in Exchange Act reports is recorded, processed, summarized and
reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management,
including the principal executive officer and the principal financial officer, as appropriate, to allow timely decisions regarding required disclosure.

An  evaluation  was  performed,  under  the  supervision,  and  with  the  participation  of  our  management,  including  our  principal  executive  officer  and
principal  financial  officer,  of  the  effectiveness  of  the  design  and  operation  of  our  disclosure  controls  and  procedures  as  of  October  1,  2021.  Based  on  this
evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective as of October 1,
2021.

Management's Annual Report on Internal Control over Financial Reporting

Our  management  is  responsible  for  establishing  and  maintaining  adequate  internal  control  over  financial  reporting.  Internal  control  over  financial
reporting is defined in Rule 13a-15(f) or 15d-15(f) promulgated under the Securities Exchange Act of 1934 as a process designed by, or under the supervision
of, the company’s principal executive and principal financial officers and effected by the company’s board of directors, management and other personnel, to
provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance
with generally accepted accounting principles and includes those policies and procedures that:

•

•

•

Pertain  to  the  maintenance  of  records  that  in  reasonable  detail  accurately  and  fairly  reflect  the  transactions  and  dispositions  of  the  assets  of  the
company;

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

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

Our  management  assessed  the  effectiveness  of  our  internal  control  over  financial  reporting  as  of  October  1,  2021.  In  making  this  assessment,  the
company’s management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control-Integrated
2013 Framework.

Based  on  this  assessment,  our  management  concluded  that,  as  of  October  1,  2021,  our  internal  control  over  financial  reporting  is  effective  based  on

those criteria.

The effectiveness of our internal control over financial reporting as of October 1, 2021 has been audited by Deloitte & Touche LLP, an independent

registered public accounting firm, as stated in their report which is included herein.

Changes in Internal Control over Financial Reporting

There  have  been  no  changes  in  the  Company’s  internal  control  over  financial  reporting  that  occurred  during  the  Company's  fiscal  quarter  ended

October 1, 2021 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

To the stockholders and the Board of Directors of MACOM Technology Solutions Holdings, Inc.

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of MACOM Technology Solutions Holdings, Inc. and subsidiaries (the “Company”) as of
October 1, 2021, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the
Treadway Commission (“COSO”). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of
October 1, 2021, based on criteria established in Internal Control - Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated
financial statements as of and for the year ended October 1, 2021, of the Company and our report dated November 15, 2021 expressed an unqualified opinion
on those financial statements.

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  Annual  Report  on  Internal  Control  Over  Financial  Reporting”
appearing in Item 9A. 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.
