ITEM 1. BUSINESS

Overview

We  design  and  manufacture  semiconductor  products  for  Telecommunications  (“Telecom”),  Industrial  and  Defense  (“I&D”)  and  Data  Center  applications.  Headquartered  in  Lowell,
Massachusetts, we have more than 70 years of application expertise, with silicon, gallium arsenide (“GaAs”) and indium phosphide (“InP”) fabrication, manufacturing, assembly and test, along with
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 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, radar, medical
systems  and  test  and  measurement.  Our  primary  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 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 twenty years. We continue to develop new products
and technologies to improve our ability to serve our primary markets. Our growth strategy is focused on 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  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  and  ISO14001  environmental  management  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. Our ability to utilize a broad array of internal proprietary process
technologies  and  commercially  available  foundry  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

3

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 this core competency 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,  patented  technologies  such  as

heterolithic microwave integrated circuit (“HMIC”), which provides high integration, high power and low loss switching capabilities for our primary markets.

Our  engineers’  radar,  optical,  microwave  and  millimeter  wave  system-level  design  expertise  allows  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 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 proliferation of wireless and wired devices from smartphones and other devices to basestations, as well as the data rich
applications  and  services  they  enable  such  as  mobile  Internet,  cloud  computing,  video-on-demand,  social  media,  global  positioning  functionality  and  location-based  services.  Growth  in  next-
generation  Internet  and  Internet  of  Things  (“IoT”)  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  gigabits  per  second  (“Gbps”)  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 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

4

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, 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 patented 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  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. The table below presents the major product families
and major applications in our primary markets.

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, application engineering staff, independent sales representatives and
distributors. Sales to our distributors accounted for 45.3%, 33.3% and 29.0% of our revenue in fiscal years 2020, 2019 and 2018, 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
13.5%, 16.1% and 12.5% of our revenue in fiscal years 2020, 2019 and 2018, 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 2019 and 2018. For fiscal years 2020, 2019 and 2018, 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 40.0%, 47.5% and 52.8% of our revenue, respectively.

6

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;

▪ 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.

We compete with Broadcom Inc. (“Broadcom”) across our primary markets, Telecom, I&D and Data Center. In the Telecom and Data Center markets, we compete with NXP Semiconductors
N.V. (“NXP”), Cree, Inc. (“Cree”), Inphi Corporation (“Inphi”), Maxlinear Inc. (“Maxlinear”) and Semtech Corporation (“Semtech”). In the I&D market, we compete with Analog Devices, Inc.
(“ADI”), 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 2, 2020, we had 646 U.S. and 158 foreign issued patents and 72 U.S. and 131 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  2020  to  2039.  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 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 allow 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, 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.

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.

8

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 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.

Employees

As  of  October  2,  2020,  we  employed  approximately  1,050  individuals  worldwide.  None  of  our  domestic  employees  are  represented  by  a  collective  bargaining  agreement;  however,  as  of
October 2, 2020, approximately 16 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.

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 date back over 70 years to the founding of Microwave
Associates, Inc. and the MACOM brand dates back over 30 years.

We completed 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 the buyer.

In August 2017, we completed the acquisition of Picometrix LLC (“Picometrix”) 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,  the  disease  caused  by  the  most  recently  discovered  coronavirus,  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

9

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 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 2, 2020, 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 an overall economic slowdown or recession and could result in adverse impacts such as increased credit and collectability risks, adverse impacts on our
suppliers,  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, actions taken to contain the virus or treat its impact, 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 new 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 repeatedly introduce, in successive years, new products that ship in volume, our revenue will
likely not grow and may decline significantly and rapidly. The development of new 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 difficult design challenges in a cost-effective, reliable manner;
our ability to design products that meet customers’ requirements; our ability to successfully design and manufacture new products at competitive prices and volumes; the acceptance by customers of
our new 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 if the product launch is
unsuccessful. Our failure to anticipate or timely develop new or enhanced products or technologies in response to technological shifts could result in decreased revenue and our competitors 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.

10

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. Factors that
could cause operating results and related expectations to fluctuate include the general economic growth or decline in the U.S. or foreign markets; the reduction or cancellation of orders by customers;
the amount of new customer orders we book and ship in any particular fiscal quarter; the 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; the success of our investments in research and development; the 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; the effects of seasonal and other changes in customer demand; the
effects of competitive pricing pressures, including decreases in average selling prices of our products; the loss of key personnel or the shortage of available skilled workers; our failure to remain
abreast of new and improved semiconductor process technologies as they emerge; the 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; further clarifications and/or changes in interpretations of existing laws and regulations
(including  those  related  to  taxes),  trade  policies  or  changes  in  laws  and  regulations,  in  the  U.S.  and  other  countries;  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, and these, as well as other 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, generally. The rate and extent to which these markets will grow, if at all, is uncertain. For
example, we anticipate significant growth in the demand for our products in Cloud Data Centers, and have focused significant internal resources to meet that anticipated demand, 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. A failure to accurately predict demand or timely respond to it with successful products will materially affect our revenues and profitability.

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

In the fiscal year ended October 2, 2020, no direct customer accounted for 10% or more of our revenue and sales to our top 10 direct and distribution customers accounted for an aggregate of
61.2%  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 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.

11

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 are subject to 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 and unexpected costs. Conversely, if we underestimate our customers’
requirements, we may have inadequate inventory, which could lead to foregone revenue opportunities, loss of potential market share and damage to customer relationships. We periodically order
materials and build a stock of finished goods inventory in advance of customer demand. This advance ordering of raw material and building of finished goods inventory has in the past and may in the
future result in excess inventory levels or unanticipated inventory write-downs. In addition, 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.

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.

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  most  recently  discovered  coronavirus,  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 conditions caused by the COVID-19 pandemic 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. 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

12

of the outbreak, its severity, actions taken to contain the virus or treat its impact 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.

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,  the  loss  of  customers,  the  loss  of  or  delay  in  market  acceptance  of  our  products,  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, even if we ultimately prevail, such claims could result in costly
litigation, divert management’s time and resources and damage our customer and supplier relationships. In addition, 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.

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 we may be involved in 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 2, 2020, we had a credit facility consisting of a term loan facility with an outstanding principle balance of $666.1 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.

13

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 and third-party
businesses. 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 another 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 in order 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 these technology failures could adversely affect our
business, operations and financial results.

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.

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.

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.

Our portfolio of marketable securities is significant and subject to market, interest and credit risk that may reduce its value.

We maintain a significant portfolio of marketable securities. Changes in the value of this portfolio could adversely affect our earnings. In particular, the value of our investments may decline due
to increases or decreases in interest rates, downgrades of money market funds, commercial paper, U.S. Treasuries and corporate bonds included in our portfolio, instability in the global financial
markets that reduces the liquidity of securities included in our portfolio and other factors. Each of these events may cause us to record charges to reduce the carrying value of our investment portfolio
or sell investments for less than our acquisition cost.

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;  the  political  and  economic  risks,  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

14

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.

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. 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 would likely 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 in a particular product area or primary market, which could
have a material adverse effect on our operations. In particular, any catastrophic loss at our Lowell, Massachusetts headquarters could materially and adversely affect our business and financial results,
revenue and profitability.

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. 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

15

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  $141.3  million  for  the  fiscal  year  ended  October  2,  2020.  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 fuel 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 not generate
any  return  on  investment,  may  take  longer  than  we  anticipate  to  generate  a  return  or  may  generate  a  return  on  investment  that  is  inadequate.  For  example,  we  have  in  the  past  and  continue  to
experience unexpected difficulties, expenses or delays in qualifying our GaN-on-Silicon process technology either internally or at one or more third party foundries and qualifying related products
with our customers, and we may not be successful in process or product qualification, manufacturing cost reduction or marketing efforts related to GaN-on-Silicon, 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 also have undertaken significant research and development efforts
aimed  at  new  products  targeting  market  segments  where  we  see  potential  for  growth  including  the  wireless  basestation  and  Cloud  Data  Center.  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  scheduling  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.

16

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 currently 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 customer’s 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 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.
Global operations involve inherent risks, 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.

17

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 these legal systems may not be as 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  59.0%  of  our  revenue  for  the  fiscal  year  ended  October  2,  2020.  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,  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. A U.S. ban on exports to one or more large OEM customers could materially reduce our revenue and reduce the value of an investment in our common stock.

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 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  recently-imposed  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 and/or regulations are implemented or if existing trade agreements are renegotiated such changes could have an adverse effect on our business, financial condition,
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.

18

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 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, shift in
approach  by  regulators  to  the  enforcement  or  scope  of  existing  regulations,  changes  in  the  interpretation  of  existing  regulations  by  regulators,  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 2, 2020, we had $908 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 2037,
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

19

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.

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.

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 the related SEC rules and executive orders. If we cannot satisfy these customers, they may choose a competitor’s products or may choose
to 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 fines and reputational harm.

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. We have invested, and continue to invest, human and technology resources into our data privacy compliance efforts. These compliance efforts may
be time-intensive and costly. 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 regimes.

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,  Broadcom,  NXP,  Cree,  Inphi,

Maxlinear, Semtech, ADI, 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 original equipment manufacturers, 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.

20

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.

Remaining competitive in the semiconductor industry requires transitioning to smaller geometry process technologies and achieving higher levels of design integration.

In  order  to  remain  competitive,  we  expect  to  continue  to  transition  our  products  to  increasingly  smaller  geometries.  In  some  instances,  we  depend  on  our  relationships  with  our  third-party
foundries to transition to smaller geometry processes successfully. Our foundries may not be able to effectively manage the transition or we may not be able to maintain our foundry relationships. If
our foundries or we experience significant delays in this transition or fail to efficiently implement this transition, our business, financial condition and results of operations could be materially and
adversely affected.

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 45.3% of our revenue for the fiscal year ended October 2, 2020, and
sales to our top three distributors, Richardson, Gateway and Pangaea, each accounted for 13.5%, 11.5% and 11.5%, respectively, 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 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  identify  such  transactions,  we  may  not  be  able  to  complete  them  on
commercially acceptable terms or at all. We also face intense competition for acquisitions from other acquirers in our industry. In the event we pursue acquisitions, investments, joint ventures and
strategic  alliances,  we  will  face  numerous  risks,  including  diverting  management’s  attention  from  normal  daily  operations  of  our  business;  difficulties  in  improving  and  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; loss of any key personnel
of the acquired company as well as their know-how, relationships and expertise, which is common following an acquisition; our inability to successfully integrate the businesses and personnel of our
acquired  companies  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 acquisitions, investments, joint ventures and strategic alliances to offset increased expenses associated with any abandoned or completed transactions; acquiring
material or unknown liabilities associated with any acquired operations; litigation frequently associated with merger and acquisition transactions; and increasing expense associated with amortization
or depreciation of intangible and tangible assets we acquire.

Past transactions, whether completed or abandoned by us, have resulted, and in the future may result, in significant time and attention, significant 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.  If  we  experience  difficulties  with  the  integration  process  or  if  the  business  of  our  acquired  companies  or  businesses  deteriorates,  the  anticipated  cost  savings,  growth
opportunities and other synergies of our acquired companies and businesses may not be realized fully or at all, or may take longer to realize than expected. Any or all of the above factors may differ
from the investment

21

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  or  fail  to  deliver  any
strategic benefits we anticipate from them and 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; arranging for sufficient supply of key raw materials and services to avoid shortages or supply
bottlenecks; building out our administrative infrastructure at the proper pace 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, workforce reductions, 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. The 2019 Plan 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 and 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 disruptive to our operations and they can involve large expenditures. In fiscal years 2020, 2019 and 2018, we incurred restructuring
charges of $1.1 million, $19.5 million and $6.3 million, respectively, 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 these initiatives 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.

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,

22

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 2, 2020, John and Susan Ocampo beneficially owned 30.0% 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.

(1) Our board of directors has approved “withhold to cover” as a tax payment method for vesting of restricted stock awards for our employees. Pursuant to an election for “withhold to cover” made by our employees
in connection with the vesting of such awards, all of which were outside of a publicly-announced repurchase plan, we withheld from such employees the shares noted in the table above to cover tax withholding
related to the vesting of their awards. The average prices listed in the above table are averages of the fair market prices at which we valued shares withheld for purposes of calculating the number of shares to be
withheld.

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  Telecommunications  (“Telecom”),  Industrial  and  Defense  (“I&D”)  and  Data  Center  applications.  Headquartered  in  Lowell,
Massachusetts,  we  have  more  than  70  years  of  application  expertise,  with  silicon,  gallium  arsenide  (“GaAs”)  and  indium  phosphide  (“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

26

who  demand  high  performance,  quality  and  reliability.  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 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 year 2020 included 53 weeks and fiscal years 2019 and 2018 each consisted of 52 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, 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.

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 (“GAAP”) 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

27

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 intangibles 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.

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

We  apply  significant  estimates  and  judgments  in  order  to  determine  the  fair  value  of  the  identified  tangible  and  intangible  assets  acquired,  liabilities  assumed  and  goodwill  recognized  in
business combinations. The value of all assets and liabilities are recognized at fair value as of the acquisition date using a market participant approach. In measuring the fair value, we utilize a number
of  valuation  techniques.  The  valuation  of  the  identifiable  assets  and  liabilities  includes  assumptions  such  as  projected  revenue,  royalty  rates,  weighted  average  cost  of  capital,  discount  rates  and
estimated useful lives. These assessments can be significantly affected by our judgments.

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

28

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 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 Industrial & Defense 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.

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 16 - 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. 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. We expect annual expense savings of approximately $50 million dollars following completion of
this action, primarily in research and development expenses. This action was completed during fiscal 2020 and we do not expect to incur further costs. The remaining charges will be paid during
fiscal year 2021.

In fiscal year 2019, restructuring charges primarily related to the 2019 Plan, as well as the Ithaca Plan and the Design Facilities Plan described further below under Comparison of Fiscal Year

Ended September 27, 2019 to Fiscal Year Ended September 28, 2018.

Refer to Note 14 - 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 20 - 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.

Comparison of Fiscal Year Ended September 27, 2019 to Fiscal Year Ended September 28, 2018

Revenue. In fiscal year 2019, our revenue decreased by $70.7 million, or 12.4%, to $499.7 million from $570.4 million for fiscal year 2018.

In fiscal year 2019, our Telecom market revenue decreased by $42.0 million, or 18.8%, compared to fiscal year 2018. The decrease was primarily due to the full year effect of our May 2018 sale
of the Japan-based long-range optical subassembly business (the “LR4 business”), lower sales of carrier-based optical semiconductor products to our Asia customer base, as well as lower sales of
products targeting fiber to the home applications.

In fiscal year 2019, our I&D market revenues increased by $19.3 million, or 10.4%, compared to fiscal year 2018. The increase was related to higher revenue from sales across the product

portfolio.

In fiscal year 2019, our Data Center market revenue decreased by $48.0 million, or 29.6%, compared to fiscal year 2018. The decrease was primarily due to lower revenue related to sales of

legacy optical products and lasers, partially offset by the recognition of $7.0 million of licensing revenue during the fiscal year ended September 27, 2019.

Gross profit. In fiscal year 2019, our gross profit decreased by $25.0 million, or 10.2%, compared to fiscal year 2018. Gross margin of 44.2% in fiscal year 2019 decreased 110 basis points,

compared to fiscal year 2018. Gross profit during 2019 was primarily impacted by lower fiscal year 2019 revenue, lower gross profit as a result of the May 2018 sale of the LR4 business and higher
inventory reserves primarily associated with Data Center products, partially offset by the recognition of $7.0 million of licensing revenue during fiscal year 2019.

Research and development. In fiscal year 2019, research and development expense decreased by $14.2 million, or 8.0%, to $163.5 million representing 32.7% of revenue, compared with $177.7

million, representing 31.2% of revenue in fiscal year 2018. Research and development expense decreased in the 2019 period primarily as a result of lower compensation-related costs, lower share-
based compensation, as well the closure of certain design facilities associated with restructuring actions. Research and development expense increased as a percentage of revenue due to the decrease
in net revenue during fiscal year 2019.

Selling, general and administrative. In fiscal year 2019, selling, general and administrative expenses decreased by $8.4 million, or 5.2%, to $153.3 million, or 30.7% of revenue, compared with

$161.7 million, or 28.3% of revenue, for fiscal year 2018. Selling, general and administrative expenses decreased in the fiscal year 2019 period primarily due to lower share-based compensation,
lower amortization expense, and lower other compensation-related costs as a result of restructuring actions. Selling, general and administrative expense increased as a percentage of revenue due to the
decrease in net revenue during fiscal year 2019.

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 impairment of equipment from construction

in process that will not be placed in service. See Note 16 - Impairments to the Consolidated Financial Statements included in this Annual Report for additional information.

Restructuring charges. In fiscal year 2019, restructuring charges were $19.5 million, or 3.9% of our revenue, compared with $6.3 million, or 1.1% of our revenue, for fiscal year 2018. During
the fiscal quarter ended June 28, 2019, we committed to the 2019 Plan. We incurred restructuring charges of $11.6 million in fiscal year 2019 under such plan, including $6.3 million of employee-
related costs, $4.0 million of impairment of fixed assets and $1.3 million of other facility-related costs.

During the fiscal quarter ended March 29, 2019, we committed to a plan to exit certain design facilities and activities (the “Design Facilities Plan”). We incurred restructuring charges of $2.5

million in fiscal year 2019 under this plan, which primarily consists of $0.3 million of employee-related costs and $2.2 million of facility-related costs. This action was completed in fiscal year 2019
and no further costs were incurred.

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 restructuring charges of $5.5 million in fiscal year 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 14 - Restructurings in this Annual report on Form 10-K for additional information.

Warrant liability gain. In fiscal year 2019, we recorded a warrant gain of $0.8 million, or 0.2% of revenue, compared to a gain of $27.6 million, or 4.8% of revenue, for fiscal year 2018. The

difference between periods was driven by a decrease in the estimated fair value of common stock warrants we issued in December 2010, which we carry as a liability at fair value.

Provision for income taxes. In fiscal year 2019, the provision for income taxes was a benefit of $39.4 million, or 7.9% of revenue, compared to a benefit of $21.5 million, or 3.8% of revenue, for

fiscal year 2018. The provision decreased primarily due to 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. For fiscal year 2018, the blended U.S. federal income tax rate was 24.5%. For fiscal year 2019, the U.S. federal
income tax rate was 21%.

The difference between the U.S. federal income tax rate of 21% and our effective income tax rate of 9.3% for fiscal year 2019 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. For fiscal year 2018, our effective income tax rate of 13.8% was primarily impacted by the 2017 Tax Cuts and Jobs Act, partially offset by the valuation allowance against our
U.S. deferred tax assets.

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
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.

Our cash flow from operating activities for fiscal year 2019 was $20.7 million and consisted of a net loss of $383.8 million, plus adjustments to reconcile our net loss to cash provided by
operating activities of $371.5 million plus changes in operating assets and liabilities of $33.0 million. Adjustments to reconcile our net loss to cash provided by operating activities of $371.5 million
primarily included impairment charges of $273.6 million, depreciation and intangible amortization expense of $104.4 million, share-based compensation expense of $23.8 million, loss on minority
equity investment of $7.5 million and amortization of deferred financing costs of $4.1 million, partially offset by an increase in deferred tax assets of $41.3 million. In addition, cash from operating
assets and liabilities was $33.0 million for fiscal year 2019, primarily driven by a decrease in accounts receivable of $27.6 million related to lower revenue from the prior fiscal year, and a decrease in
inventory of $15.0 million, partially offset by a decrease in accounts payable of $12.2 million related to timing of vendor payments. The fiscal year 2019 decrease in accounts receivable balances was
primarily due to lower revenue compared to fiscal year 2018.

Cash Flow from Investing Activities:

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.

Our cash flow used in investing activities for fiscal year 2019 consisted primarily of $174.1 million in purchases of short-term investments, proceeds of $173.0 million related to the sale of

short-term investments, capital expenditures of $38.0 million and $5.5 million in proceeds related to the sale of assets.

Cash Flow from Financing Activities:

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 9 -
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.

During fiscal year 2019, our cash used in financing activities of $5.8 million was primarily related to $6.9 million of principal payments associated with our Term Loans (as defined in Note 9 -
Debt to our Consolidated Financial Statements included in this Annual Report) and $4.1 million in purchases of stock associated with employee tax withholdings, partially offset by $7.2 million of
proceeds from stock option exercises and employee stock purchases.

Liquidity

As  of  October  2,  2020,  we  held  $129.4  million  of  cash  and  cash  equivalents,  primarily  deposited  with  financial  institutions  as  well  as  $203.7  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 2, 2020, cash held by our indefinitely reinvested foreign subsidiaries was $41.2 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 2, 2020, we had $160.0 million in borrowing capacity under our Revolving Facility (as defined in Note 9 - Debt to our Consolidated Financial Statements included in this Annual Report), of
which we may borrow up to $50.0 million without being subject to certain financial covenants.

We plan to use our remaining available cash and cash equivalents, short-term investments, and as deemed appropriate our borrowing capacity under our Revolving Facility 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, cash generated from operations and borrowing availability under our Revolving Facility 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.

OFF-BALANCE SHEET ARRANGEMENTS

As of October 2, 2020, we had no material transactions that meet the definition of an off-balance sheet arrangement required to be disclosed pursuant to SEC Regulation S-K Item 303(a)(4)(ii).

in fixed payments associated with a power purchase agreement that is expected to commence in fiscal 2022 and has a 15-year term.

As  of  October  2,  2020,  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.

OTHER MATTERS

Inflation did not have a material impact upon our results of operations during the three-year period ended October 2, 2020.

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. In addition, the value of our warrant liability is based on the underlying price of our common stock and changes in its value could significantly
impact our warrant liability expense. Substantially all of the warrants were exercised and common stock was issued on November 11, 2020 and the remaining warrants expire December 21, 2020.

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 and revolving credit facility are variable interest rates based on our lender’s 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  2,  2020,  we  had  $666.1  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 $6.7 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. Increases 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. Conversely, decreases in the value of the U.S. dollar relative to other
currencies  could  result  in  our  products  being  more  expensive  to  certain  customers  and  could  reduce  or  delay  orders,  or  otherwise  negatively  affect  how  they  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.

Opinion on the Financial Statements

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

We have audited the accompanying consolidated balance sheets of MACOM Technology Solutions Holdings, Inc. and subsidiaries (the "Company") as of October 2, 2020 and September 27,

2019, and the related consolidated statements of operations, comprehensive loss, stockholders’ equity, and cash flows, for each of the three years in the period ended October 2, 2020, 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 2, 2020
and September 27, 2019, and the results of its operations and its cash flows for each of the three years in the period ended October 2, 2020, 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 2, 2020, 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 18, 2020, expressed an unqualified opinion on the Company's internal control over financial reporting.

Change in Accounting Principle

As discussed in Note 2 to the financial statements, on the first day of its fiscal year 2020, the Company adopted Accounting Standards Update 2016-02, Leases (Topic 842) using the modified

retrospective approach.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a

public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and
regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether
due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial
statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial
statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit 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 2, 2020, the Company has inventories of
$91.6 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.

37

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 operating management to determine whether 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.

MACOM TECHNOLOGY SOLUTIONS HOLDINGS, INC.

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  segment,  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, 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. The fiscal year 2020 included 53 weeks and fiscal years 2019 and 2018 included 52 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.

Divested Businesses and Discontinued Operations—In the first quarter of fiscal year 2018, we divested AppliedMicro's compute business (the “Compute business”). The operating results of
the Compute business are reflected in discontinued operations. In the third quarter of fiscal year 2018, we divested our Japan-based long-range optical subassembly business (the “LR4 business”).
The operating results of the LR4 business have been reflected in our continuing operations up through the May 10, 2018 sale date, with the $34.3 million loss on disposal recorded as other expense.
See Note 22 - Divested Business and Discontinued Operations for additional information.

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 based upon third
party  pricing  at  period  end.  Unrealized  gains  and  losses  that  are  deemed  temporary  in  nature  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 other than temporary results in a charge to earnings and the corresponding establishment of a new cost basis for 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

44

are included in other income and expense 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 line in our Consolidated Statements of Operations.

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,  at  cost  less  impairment,  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:

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

Asset Classification

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 carrying value of the reporting unit to the fair value of the Company. 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 implied fair values. We performed our annual impairment test of our goodwill and
indefinite-lived intangible assets and the results of this test indicated that our goodwill and indefinite-lived intangible assets were not impaired as of August 28, 2020. There were no indicators of
impairment noted during the fiscal year ended October 2, 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.

45

 
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
years 2019 and 2018, we recorded impairment charges, see Note 16 - 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.

Revenue Recognition—Substantially all of our revenue is derived from sales of high-performance RF, microwave, millimeterwave and lightwave semiconductor solutions into three primary

markets: Telecom, I&D and Data Center.

In fiscal year 2018, we recognized revenue under ASC 605, Revenue Recognition, when: (i) persuasive evidence of an arrangement existed; (ii) delivery or services had been rendered; (iii) the
price  was  fixed  or  determinable;  and  (iv)  collectability  was  reasonably  assured.  We  recognized  revenue  with  the  transfer  of  title  and  risk  of  loss  and  provided  for  reserves  for  returns  and  other
allowances.

In  fiscal  years  2019  and  2020,  we  recognized  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 or services, 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
(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 at the date of adoption or as of September 27, 2019 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

46

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 (loss) income per share is computed by dividing net (loss) income by the weighted-average number of common shares outstanding during the period, excluding
the dilutive effect of common stock equivalents. Diluted net (loss) income per share reflects the dilutive effect of common stock equivalents, such as stock options, warrants and restricted stock units,
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 net asset 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 are classified as Level 3 due to unobservable inputs. We use
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.

Share-Based Compensation—We account for all share-based compensation arrangements using the fair value method. We recognize compensation expense on a straight-line basis over the
expected or requisite service period of the award, which is generally the vesting period of each separately vesting tranche, 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

47

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, 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 have maintained 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  2,  2020  and
September  27,  2019.  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 2020

On the first day of our fiscal year 2020, we adopted Accounting Standards Update (“ASU”) 2016-02, Leases (Topic 842) (“ASC 842”), which requires lease arrangements be presented on the
lessee’s balance sheet by recording a right-of-use (“ROU”) asset and a lease liability equal to the present value of related future minimum lease payments. We adopted the new lease guidance using
the modified retrospective approach and the transition method available in accordance with ASU 2018-11, Leases (Topic 842): Targeted Improvements, which provides the option to use the effective
date as the date of initial application of the guidance. As a result, the comparative information for prior periods has not been adjusted and continues to be reported in accordance with the accounting
standards in effect for those periods under the previously applicable guidance. We elected the “practical expedients package of three” permitted under the transition guidance within ASC 842, which
permitted  us  to  carry  forward  our  historical  assessments  of  whether  contracts  contain  leases,  lease  classification,  and  initial  direct  costs,  for  leases  in  existence  prior  to  September  28,  2019.  We
evaluated our identified leases and applied the new lease guidance as discussed in Note 10 - Leases.

At  the  effective  date,  the  adoption  of  ASC  842  resulted  in  an  increase  to  our  total  assets  of  approximately  $37.1  million,  an  increase  to  our  total  liabilities  of  approximately  $39.0  million,
primarily related to capitalization of operating leases, and a decrease to our retained earnings of approximately $1.9 million primarily due to derecognition of financing obligations and associated
assets established under ASC 840, Leases.

We have operating leases for certain facilities as well as manufacturing and office equipment. Based on the present value of lease payments for the remaining lease term of our existing leases,
we recognized $37.7 million and $43.6 million of both operating ROU assets and operating lease liabilities, respectively, on our consolidated balance sheet upon adoption of ASC 842 on September
28, 2019. The difference between the ROU asset and liability represents deferred rent and lease incentives of approximately $5.9 million, recorded as a reduction to our gross ROU assets.

We have finance leases for our corporate headquarters, including our fabrication facility, and to a lesser extent, various manufacturing equipment. Upon the adoption of ASC 842 on September
28, 2019, we derecognized the previous financed assets and financing obligation for our built-to-suit corporate headquarters and recorded a finance lease asset and liability. We also recorded finance
lease assets and liabilities for various manufacturing equipment. On September 28, 2019 we recognized a finance lease ROU asset and finance lease liability of $35.7 million and $31.8 million,
respectively, on our consolidated balance sheet. The difference

48

between the ROU asset and liability represents net prepaid rent for our corporate headquarters, which is recorded as part of the finance lease ROU asset and is being amortized on a straight-line basis
over the remaining lease term.

The adoption of the new lease guidance did not have a material impact to the Consolidated Statement of Operations or Cash Flows, or earnings per share for the fiscal year ended October 2,

2020.

Pronouncements for Adoption in Subsequent Periods

In  June  2016,  the  Financial  Accounting  Standards  Board  (“FASB”)  issued  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. We adopted this standard on the first day of our fiscal year 2021, October 3, 2020. The adoption of this standard did not have a material impact on our
consolidated financial statements.

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, it 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.

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  2,  2020  and  September  27,  2019,  $3.5  million  and  $8.5  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. The decrease in contract liabilities during the fiscal year ended October 2, 2020 was primarily from recognition of revenue for services
provided, partially offset by the deferral of revenue for funds received prior to when certain of our customers obtain control of the product or services.

During the fiscal years ended October 2, 2020 and September 27, 2019, we recognized net sales of $1.9 million and $7.6 million, respectively, that were included in the contract liabilities balance

at the beginning of the period.

4. INVESTMENTS

We have determined that the gross unrealized losses on available for sale securities at October 2, 2020 and September 27, 2019 are temporary in nature. We review our investments to identify
and evaluate investments that have indications of possible impairment. 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 temporary include the length of time and extent to which fair value has been less than the cost basis, 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.

We received proceeds from sales of available-for-sale securities of $183.9 million, $173.0 million and $100.4 million during the fiscal years 2020, 2019 and 2018, respectively. Gross realized

gains and losses from such sales were immaterial during the fiscal years ended October 2, 2020, September 27, 2019 and September 28, 2018 and were recorded within other expense.

Other Investments— As of October 2, 2020 and September 27, 2019, 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.  The  carrying  value  of  this
investment was $2.5 million and $5.0 million as of October 2, 2020 and September 27, 2019, respectively.

Also included in long-term investments, is a minority investment of less than 20% of the outstanding equity of Compute. This investment was acquired in conjunction with the divestiture of the

Compute business during our fiscal year 2018, had an initial value

50

 
 
 
 
 
of $36.5 million and is accounted for using the equity method. We have no obligation to provide further funding to Compute. This investment value is updated quarterly based on our proportionate
share of the losses or earnings of Compute, as well as any changes in Compute's equity, utilizing the equity method. During fiscal years 2020, 2019 and 2018, we recorded $3.4 million, $7.5 million
and $10.4 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 2020 and 2019 include
non-cash  gains  of  $16.6  million  and  $10.8  million,  respectively,  associated  with  changes  in  Compute’s  equity.  The  carrying  value  of  this  investment  was  $15.2  million  and  $18.6  million  as  of
October 2, 2020 and September 27, 2019, respectively.

5. FAIR VALUE

9. DEBT

As of October 2, 2020, we are party to a credit agreement dated as of May 8, 2014 with a syndicate of lenders and Goldman Sachs Bank USA (“Goldman Sachs”), 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”).

As of October 2, 2020, the Credit Agreement consisted 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 will mature in November 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%.

All principal amounts outstanding and interest rate information as of October 2, 2020, for the Credit Agreement were as follows (in thousands, except rate data):

As of October 2, 2020, approximately $5.1 million of deferred financing costs remain unamortized, of which $4.8 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  $0.3  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.

53

 
The Term Loans are payable in quarterly principal installments of approximately $1.7 million on the last business day of each calendar quarter, with the remainder due on the maturity date. In
the event that we divest a business, the net cash proceeds of the divestment are generally required, subject to certain exceptions, to be applied to repayment of outstanding Term Loans except to the
extent we reinvest such proceeds in assets useful for our business within 18 months of receiving the proceeds. If we enter into a binding agreement to reinvest such proceeds within 18 months of
receiving them, we have until the later of 18 months following our receipt of the proceeds and six months following the date of such agreement to complete the reinvestment.

As  of  October  2,  2020,  we  had  $160.0  million  of  borrowing  capacity  under  our  Revolving  Facility,  of  which  we  may  borrow  up  to  $50.0  million  without  being  subject  to  certain  financial

covenants.

10. 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.  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 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 statement 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.

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 year ended October 2, 2020, we contributed $2.3 million to
our 401(k) Plan for calendar year 2019. During the fiscal year ended September 27, 2019, we contributed $2.6 million to our 401(k) Plan for calendar year 2018.

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 $1.0 million, $1.1 million and
$1.2 million for fiscal years 2020, 2019 and 2018, respectively.

13. 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  2020  and  2019,  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 $1.8 million, respectively.

Purchase  Commitments—As  of  October  2,  2020,  we  had  outstanding  non-cancelable  purchase  commitments  of  $33.8  million  primarily  for  purchases  of  services  and  inventory  supply

arrangements. In addition, we have $27.0 million in fixed payments associated with a power purchase agreement that is expected to commence in fiscal 2022 and has a 15-year term.

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 2, 2020.

14. RESTRUCTURINGS

We have periodically implemented restructuring actions in connection with broader plans to reduce staffing, our internal manufacturing footprint and overall operating costs. The restructuring
expenses are primarily comprised of direct and incremental costs related to headcount reductions including severance and outplacement fees for the terminated employees, as well as facility closure
costs.

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 will be paid during fiscal year 2021.

During the fiscal quarter ended December 29, 2017, we initiated plans to restructure and close our facilities in Long Beach, California, Belfast, United Kingdom and Sydney, Australia (the
“Long Beach, Belfast and Sydney Plan”). The operations from the Long Beach facility were consolidated into our other California locations in order to achieve operational synergies. The Belfast and
Sydney facilities were closed as we discontinued certain product development activities that were performed in those locations. During the fiscal year ended September 28, 2018, we incurred $6.3
million, including $2.8 million of employee-related costs and $3.5 million of facility-related costs. This action was complete in fiscal 2018, no further costs were incurred and all remaining payments
were made in the fiscal year ended September 27, 2019.

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

59

warranty obligations and utilizes historical product failure rates. Should actual warranty obligations differ from estimates, revisions to the warranty liability may be required.

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 14 - 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. During the
fiscal quarter ended June 28, 2019, 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 the fiscal quarter ended June 28, 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.

During fiscal year 2018, we recorded impairment charges of $6.6 million related to property and equipment and other assets.

See Note 14 - Restructurings for information related to property and equipment impaired as part of our restructuring actions.

As  of  October  2,  2020,  we  had  $908.0  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 infinite. 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 2, 2020 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 $277.4 million of valuation allowance as of October 2, 2020 relates primarily to federal and state NOLs, tax credit carryforwards and a partial valuation allowance on tax credits in Canada
of $8.0 million whose recovery is not considered more likely than not. The $252.5 million of valuation allowance as of September 27, 2019 related primarily to federal and state NOLs, tax credit
carryforwards and a partial valuation allowance on tax credits in Canada of $19.0 million, for which recovery is not considered likely. The change during the fiscal year ended October 2, 2020 of
$24.9 million primarily relates to an increase in our state NOLs and an increase in our federal and state tax credits.

Our effective tax rates differ from the federal and statutory rate as follows:

Federal statutory rate
Change in valuation allowance
Provision to return adjustments
Research and development credits
Global Intangible Low Taxed Income
Foreign rate differential
Warrant liability
Intra-entity license transfer
Nondeductible compensation expense
State taxes net of federal benefit
Section 382 adjustment
Nondeductible legal fees
2017 tax reform
Other permanent differences

For fiscal years 2020, 2019 and 2018, the effective tax rates on $41.6 million, $423.2 million and $155.2 million, respectively, of pre-tax loss from continuing operations were (10.9)%, 9.3%

and 13.8%, respectively. The effective income tax rates for fiscal years 2020, 2019 and 2018 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, and a fair market value adjustment of warrant liability. For fiscal year 2020, the effective tax rate was also impacted by
an adjustment in our Section 382 limitation which increased our

63

 
 
California NOL carryforwards and the inclusion of Global Intangible Low Taxed Income. For fiscal year 2019, the effective tax rate was also impacted by a change in our NOL carryforward due to
an adjustment in our Section 382 limitation from a prior period acquisition and 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. For fiscal year 2018, the effective tax rate was also impacted by the Tax Cuts and Jobs Act
(the “Tax Act”).

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.

During fiscal year 2019 we finalized our calculation of the one-time deemed repatriation of gross foreign earnings and profits, totaling $156.8 million, which resulted in approximately $86.7
million in U.S. taxable income for the year ended September 28, 2018 with Grand Cayman and Ireland accounting for $59.7 million and $25.6 million, respectively. Due to the fact that we are in a
full U.S. valuation allowance, this one-time deemed repatriation had no impact on our tax expense for fiscal year 2018.

On December 22, 2017, the U.S. Congress enacted the Tax Act, which enacted a wide range of changes to the U.S. corporate income tax system, many of which differ significantly from the
provisions of the previous U.S. tax law. The Tax Act also transitions international taxation from a worldwide system with deferral to a modified territorial system and includes base erosion prevention
measures  on  non-U.S.  earnings,  which  has  the  effect  of  subjecting  certain  earnings  of  our  foreign  subsidiaries  to  U.S.  taxation  as  Global  Intangible  Low  Taxed  Income.  These  changes  became
effective in our fiscal year ending September 29, 2018.

The liability for unrecognized tax benefits was $0.3 million as of October 2, 2020, September 27, 2019 and September 28, 2018 and there were no additions or reductions to this liability during
fiscal years 2020 or 2019. The balance of the unrecognized tax benefit as of October 2, 2020, is included in other long-term liabilities in the accompanying Consolidated Balance Sheets. The entire
balance of unrecognized tax benefits, if recognized, will reduce income tax expense.

It is our policy to recognize any interest and penalties accrued related to unrecognized tax benefits in income tax expense. During fiscal year 2020, we did not make any payment of interest and
penalties. We did not accrue for the payment of interest and penalties in the Consolidated Balance Sheets as of October 2, 2020 or September 27, 2019, as the remaining unrecognized tax benefits
would only serve to reduce our current federal and state NOL carryforwards, if ultimately recognized.

A summary of the fiscal tax years that remain subject to examination, as of October 2, 2020, for the Company’s significant tax jurisdictions are:
Jurisdiction

United States—federal
United States—various states
Ireland

Tax Years Subject to Examination
2018 - forward
2016 - forward
2016 - forward

Generally, we are no longer subject to federal income tax examinations for years before 2018, except to the extent of loss and tax credit carryforwards from those years.

19. SHARE-BASED COMPENSATION PLANS

Stock Plans

We have three equity incentive plans: the Amended and Restated 2009 Omnibus Stock Plan (“2009 Plan”), the 2012 Omnibus Incentive Plan, as amended (“2012 Plan”) and the 2012 Employee

Stock Purchase Plan, as amended and restated (“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. Under the 2012 Plan, we have the ability to issue incentive stock options (“ISOs”), nonqualified stock options (“NQs”), stock appreciation rights, restricted stock (“RSAs”), restricted
stock units (“RSUs”), performance-based stock units (“PRSUs”) and other equity-based awards to employees, directors and outside consultants. The ISOs and NQs must be granted at a price per
share not less than the fair value of our common stock on the date of grant. Options granted to date primarily vest based on certain market-based and performance-based criteria as described below.
Certain  of  the  share-based  awards  granted  and  outstanding  as  of  October  2,  2020,  are  subject  to  accelerated  vesting  upon  a  sale  of  the  Company  or  similar  changes  in  control.  Options  granted
generally have a term of four to seven years.

As of October 2, 2020, we had 17.0 million shares available for future issuance under the 2012 Plan and 3.6 million shares available for issuance under our ESPP.

Outside of the three 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 2, 2020, we had 225,523 ISU awards outstanding with a fair

64

value of $7.6 million and an associated accrued compensation liability of $4.6 million. As of September 27, 2019, we had approximately 195,598 ISU awards outstanding with a fair value of $2.0
million recorded as an accrued compensation liability. During fiscal years 2020, 2019 and 2018, 62,344, 69,035 and 68,813 ISU awards vested and were paid at a fair value of $1.9 million, $1.2
million and $1.4 million, respectively. We recorded an expense for these ISU awards of $4.4 million in fiscal year 2020, primarily as a result of an increase in our stock price, and we recorded an
expense of $1.3 million and a gain of $1.1 million in fiscal years 2019 and 2018, respectively. These expenses are not included in the share-based compensation expense totals below.

Employee Stock Purchase Plan

The  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 ESPP, the board of directors has limited discretion to set the length of the offering periods thereunder. As of October 2, 2020, total unrecognized compensation cost
related to the ESPP was $0.3 million. In fiscal years 2020, 2019 and 2018, 272,469, 421,777 and 305,851 shares of common stock were issued under the ESPP, respectively.

The 2012 Plan contains an “evergreen” provision, pursuant to which the number of shares of common stock available for issuance under the 2012 Plan can be increased on the first day of each
fiscal year by the lesser of (a) 4.0% of outstanding common stock on a fully diluted basis as of the end of the immediately preceding fiscal year, (b) 1.9 million shares of common stock and (c) a
lesser amount determined by the board of directors; provided, however, that any shares from any increases in previous years that are not actually issued will continue to be available for issuance under
the 2012 Plan. The ESPP also contains an “evergreen” provision, pursuant to which the number of shares of common stock available for issuance under the ESPP can be increased on the first day of
each fiscal year by the lesser of (a) 1.25% of outstanding common stock on a fully diluted basis as of the end of the immediately preceding fiscal year, (b) 550,000 shares of common stock and (c) a
lesser amount determined by the board of directors; provided, however, that any shares from any increases in previous years that are not actually issued will continue to be available for issuance under
the ESPP.

In fiscal year 2020, pursuant to the evergreen provisions, the number of shares of common stock available for issuance under the 2012 Plan and the ESPP were increased by 1.9 million shares

and 550,000 shares, respectively.

options exercised was $1.4 million, $0.7 million and $0.9 million for fiscal years 2020, 2019 and 2018, respectively.

Stock Options with Market-based Vesting Criteria

We  grant  NQs  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. In the event that our common stock achieves the
target price per share based on a 30-day trailing average prior to the end of the estimated service period, any remaining unamortized compensation cost will be recognized.

There were no stock options with market-based vesting criteria granted for fiscal year 2020. Stock options with market-based vesting criteria granted for fiscal years 2019 and 2018 were 585,000

and 325,000, respectively, at weighted average grant date fair values of $7.47 and $15.52 per share, or total grant date fair value of $2.4 million and $5.0 million, respectively.

These NQs with market-based vesting criteria were valued using a Monte Carlo simulation model. The weighted average Monte Carlo input assumptions used for calculating the fair value of

these market-based stock options are as follows:

Risk-free interest rate
Expected term (years)
Expected volatility

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 2,
2020 was $1.7 million.

The total fair value of restricted stock awards and units vested was $19.1 million, $11.7 million and $19.7 million for the fiscal years 2020, 2019 and 2018, 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 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. As of October 2, 2020, the performance condition for 147,929 target shares had been met, and 443,787 shares with a total grant date fair value of $7.9 million vested in
November 2020 when the service condition was achieved. During fiscal year 2020, we granted 132,668 PRSUs and 168,481 were forfeited. The amount of incremental PRSU awards that could
ultimately vest if all performance criteria are achieved would be 1,388,898 shares assuming a maximum of 300% of the targeted shares.

We granted 200,000 market-based RSUs 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

66

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

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  2,  2020  and  September  27,  2019.  The
outstanding  shares  of  common  stock  as  of  October  2,  2020  presented  in  the  accompanying  Consolidated  Statements  of  Stockholders’  Equity,  excludes  5,414  unvested  shares  of  restricted  stock
awards, issued as compensation to employees that were subject to forfeiture. There were no unvested shares of restricted stock awards that were subject to forfeiture as of September 27, 2019.

Common Stock Warrants—In March 2012, we issued warrants to purchase 1,281,358 shares of common stock for $14.05 per share. The warrants expire December 21, 2020, or earlier as per
the terms of the agreement, including immediately following consummation of a sale of all or substantially all assets or capital stock or other equity securities, including by merger, consolidation,
recapitalization  or  similar  transactions.  We  do  not  currently  have  sufficient  registered  and  available  shares  to  immediately  satisfy  a  request  for  registration,  if  such  a  request  were  made.  As  of
October 2, 2020, no exercise of the warrants had occurred and no request had been made to register the warrants or any underlying securities for resale by the holders. On November 11, 2020, we
issued 850,311 shares of common stock related to a cashless exercise of 1,270,679 shares associated with the warrants.

We are recording 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.

21. 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, MACOM's President and Chief Executive Officer, has an equity interest of less than 1% in Mission.

Darktrace Limited (“Darktrace”), a MACOM vendor and an affiliate of director Peter Chung, provides us with cybersecurity technology and cyber defense offerings. During fiscal year 2020

and 2019 we made payments of approximately $0.1 million and $0.1 million, respectively, to Darktrace.

Cadence Design Systems, Inc. (“Cadence”) provides us with certain engineering licenses on an ongoing basis. Geoffrey Ribar, who joined our board of directors on March 22, 2017, served as an
officer of Cadence through September 30, 2017 and served as a Senior Advisor to Cadence until March 31, 2018. During fiscal year 2018, we made payments of $4.1 million to Cadence prior to
March 31, 2018.

22. DIVESTED BUSINESS AND DISCONTINUED OPERATIONS

Divested Business

On  May  10,  2018,  we  completed  the  sale  and  transfer  of  the  LR4  business,  pursuant  to  an  Asset  Purchase  and  Intellectual  Property  License  Agreement,  dated  April  30,  2018  (the  “LR4
Agreement”). As a result of the transaction, during fiscal year 2018 we recorded a loss on disposal of $34.3 million associated with LR4 business as other expense, comprised of expected proceeds of
$17.2 million less the carrying value of assets sold. The transaction did not meet the criteria of discontinued operations.

During the quarter ended July 3, 2020, we received payment of $13.2 million for our outstanding net receivable with the buyer, inclusive of $11.0 million related to the sale of the LR4 business.

Discontinued Operations

67

On October 27, 2017, we entered into a purchase agreement to sell the Compute business. In consideration for the transfer and sale of the Compute business, we received an equity interest in the
buyer valued at approximately $36.5 million, representing the carrying value of the assets divested and representing less than 20.0% of the buyer's total outstanding equity. The operations of the
Compute business were accounted for as discontinued operations through the date of divestiture.

As of October 2, 2020, we had warrants outstanding which were reported as a liability on the consolidated balance sheet. During fiscal years 2019 and 2018, we recorded gains of $0.8 million

and $27.6 million, associated with adjusting the fair value of the

68

 
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  2020  and  2019,  we
excluded the effects of the warrant and the respective 639,133 and 214,303 potential shares of common stock issuable upon exercise of warrants as the inclusion would be anti-dilutive. During the
fiscal year ended September 28, 2018, we adjusted the numerator to exclude the warrant gain $27.6 million, and we also adjusted the denominator for the dilutive effect of the incremental warrant
shares of 569,667 under the treasury stock method. For fiscal year 2018, the table above excludes the effects of 375,940 shares of potential shares of common stock issuable upon exercise of stock
options, restricted stock and restricted stock units as the inclusion would be anti-dilutive. The table excludes the effects of 1,755,973 and 386,552 shares for fiscal years 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.

24. SUPPLEMENTAL CASH FLOW INFORMATION

As of October 2, 2020 and September 27, 2019, we had $0.6 million and $0.6 million, respectively, in unpaid amounts related to purchases of property and equipment included in accounts
payable and accrued liabilities. These amounts have been excluded from the payments for purchases of property and equipment in the accompanying Consolidated Statements of Cash Flows until
paid.

During fiscal years 2019 and 2018, we capitalized $1.5 million and $18.4 million, respectively, of net construction costs relating to the facility in Lowell, Massachusetts, of which $0.3 million

and $12.7 million, respectively, were accounted for as a non-cash transaction as the costs were paid by the developer.

26. GEOGRAPHIC AND SIGNIFICANT CUSTOMER INFORMATION

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”)  definition  of  the  business  and  the  nature  and  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. The results of operations provided to and analyzed by the CODM are at the consolidated level and accordingly, key
resources  and  assessments  of  performance  are  performed  at  the  consolidated  level.  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 2, 2020. Based on this evaluation, our principal executive officer and principal financial officer concluded that our
disclosure controls and procedures were effective as of October 2, 2020.

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 2, 2020. In making this assessment, the company’s management used the criteria set

forth by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in Internal Control-Integrated 2013 Framework.

Based on this assessment, our management concluded that, as of October 2, 2020, our internal control over financial reporting is effective based on those criteria.

The effectiveness of our internal control over financial reporting as of October 2, 2020 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 2, 2020 that have materially affected, or

are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Opinion on Internal Control over Financial Reporting

Report of Independent Registered Public Accounting Firm

We have audited the internal control over financial reporting of MACOM Technology Solutions Holdings, Inc. and subsidiaries (the “Company”) as of October 2, 2020, 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 2, 2020, 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 2, 2020, of the Company and our report dated November 18, 2020, 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.

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

MACOM Technology Solutions Holdings, Inc., a Delaware corporation (“Company,” “we,” “us” and “our”), has one class of securities registered pursuant to Section 12 of the Securities
Exchange Act of 1934: our common stock, par value $0.001 per share. The following is a summary of the general terms and provisions of our common stock. This summary does not purport to be
complete  and  is  subject  to  and  qualified  in  its  entirety  by  reference  to  the  provisions  of  our  Fifth  Amended  and  Restated  Certificate  of  Incorporation  (“Certificate  of  Incorporation”)  and  Third
Amended and Restated Bylaws (“Bylaws”), and applicable provisions of Delaware General Corporation Law (the “DGCL”).

Our authorized capital stock consists of 300,000,000 shares of common stock, par value $0.001 per share, and 10,000,000 shares of preferred stock, par value $0.001 per share.

Common Stock

Voting Rights. The holders of common stock are entitled to one vote per share on all matters to be voted on by the common stockholders. The holders of common stock are not entitled to

cumulative voting in the election of directors. Therefore, holders of a majority of the shares voting for the election of directors can elect all directors.

Dividend Rights. Subject to preferences of any outstanding shares of preferred stock, the holders of common stock are entitled to receive ratably any dividends our board of directors (our

“Board”) may declare out of funds legally available for the payment of dividends.

Liquidation Rights. If we are liquidated, dissolved or wound up, the holders of common stock are entitled to share pro rata in all assets remaining after payment of, or provision for, our

liabilities and liquidation preferences of any outstanding shares of preferred stock.

Rights and Preferences. Holders of common stock have no pre-emptive rights or rights to convert their common stock into any other securities. There are no redemption or sinking fund

provisions applicable to the common stock. All outstanding shares of common stock are fully paid and non-assessable.

Preferred Stock

Pursuant to our Certificate of Incorporation, our Board has the authority, without further action by the stockholders, to issue up to 10,000,000 shares of preferred stock, par value $0.001 per
share, from time to time in one or more series. Our Board also has the authority to fix the designations, voting powers, preferences, and relative, participating, optional or other special rights, and the
qualifications, limitations or restrictions of, any series of preferred stock, including dividend rights, conversion rights, voting rights, terms of redemption and liquidation preferences, any or all of
which may be greater than the rights of the common stock. Our Board, without stockholder approval, can issue preferred stock with voting, conversion or other rights that could adversely affect the
voting power and other rights of the holders of common stock. The issuance of preferred stock may decrease the market price of our common stock.

Pre-emptive Rights

Under the DGCL a stockholder is not entitled to pre-emptive rights to subscribe for additional issuances of common stock or any other class or series of common stock or any security

convertible into such stock in proportion to the shares that are owned unless there is a provision to the contrary in the Certificate of Incorporation. Our Certificate of Incorporation does not provide
that our stockholders are entitled to pre-emptive rights.

Registration Rights

We are party to a Second Amended and Restated Investor Rights Agreement with certain holders of our capital stock and warrants (as amended, the “Second Amended and Restated Investor
Rights Agreement”), which provides for rights relating to the registration of the shares of our common stock held by them and issuable to them upon exercise of the warrants held by them. These
securities are referred to as “registrable securities.”

Specifically, the Second Amended and Restated Investor Rights Agreement provides for, subject to certain conditions, (i) a limited number of demand registration rights, which require us to
effect  a  registration  of  registrable  securities  with  the  U.S.  Securities  and  Exchange  Commission  upon  a  written  request  from  certain  holders  of  registrable  securities;  (ii)  unlimited  shelf  demand
registration  rights  after  we  are  eligible  to  use  a  registration  statement  on  Form  S-3  upon  request  from  the  holders  of  at  least  five  percent  (5%)  of  the  outstanding  registrable  securities;  and  (iii)
piggyback registration rights, subject to certain conditions, which may require us to register registrable securities if we propose to register any of our equity securities for sale to the public (whether
for our account or the account of any stockholder).

In connection with any registration effected pursuant to the terms of the Second Amended and Restated Investor Rights Agreement, we will be required to pay for all of the fees and expenses
incurred  in  connection  with  such  registration,  including  registration  fees,  filing  fees  and  printing  fees.  However,  the  underwriting  discounts  and  commissions  payable  in  respect  of  registrable
securities included in any registration will be paid by the persons including such registrable securities in any such registration. We have also agreed to indemnify the holders of registrable securities
against losses, claims, actions, damages, liabilities and expenses under certain circumstances with respect to each registration effected pursuant to the Second Amended and Restated Investor Rights
Agreement subject to limited exceptions.

Anti-Takeover Effects of Certain Provisions of Our Certificate of Incorporation, Our Bylaws and the DGCL

Provisions of our Certificate of Incorporation, our Bylaws and the DGCL could have the effect of delaying or preventing a third party from acquiring us, even if the acquisition would benefit
our stockholders. These provisions may delay, defer or prevent a tender offer or takeover attempt of our Company that a stockholder might consider in the stockholder’s best interest, including those
attempts  that  might  result  in  a  premium  over  the  market  price  for  the  shares  held  by  our  stockholders.  These  provisions  are  intended  to  enhance  the  likelihood  of  continuity  and  stability  in  the
composition of our Board and in the policies formulated by our Board and to reduce our vulnerability to an unsolicited proposal for a takeover that does not contemplate the acquisition of all of our
outstanding shares, or an unsolicited proposal for our restructuring or sale of all or part of our business.

Authorized but Unissued Shares of Common Stock and Preferred Stock

Our authorized but unissued shares of common stock and preferred stock are available for our Board to issue without stockholder approval. As noted above, our Board, without stockholder
approval, has the authority under our Certificate of Incorporation to issue preferred stock with rights superior to the rights of the holders of common stock. As a result, preferred stock could be issued
quickly,  could  adversely  affect  the  rights  of  holders  of  common  stock  and  could  be  issued  with  terms  calculated  to  delay  or  prevent  a  change  of  control  or  make  removal  of  management  more
difficult.  We  may  use  the  additional  authorized  shares  of  common  or  preferred  stock  for  a  variety  of  corporate  purposes,  including  future  public  offerings  to  raise  additional  capital,  corporate
acquisitions and employee benefit plans. The existence of our authorized but unissued shares of common stock and preferred stock could render more difficult or discourage an attempt to obtain
control of our Company by means of a proxy contest, tender offer, merger or other transaction.

Classified Board; Election and Removal of Directors

Our Certificate of Incorporation provides for the division of our Board into three classes, as nearly as equal in number as possible, with the directors in each class serving for three-year
terms, and one class being elected each year by our stockholders. Our directors can be removed only for cause and, subject to specified exceptions, vacancies on our Board may be filled only by the
affirmative vote of a majority of the directors then in office. Further, only our Board may change the size of our Board. Because this system of electing, appointing and removing directors generally
makes it more difficult for stockholders to replace a majority of our Board, it may discourage a third party from initiating a tender offer or otherwise attempting to gain control of our Company, and
may maintain the incumbency of our Board.

Stockholder Action; Special Meetings of Stockholders

Our Certificate of Incorporation and our Bylaws provide that no action shall be taken by the stockholders except at an annual or special meeting of the stockholders called in accordance with

our Bylaws and no action shall be taken by the stockholders by written consent.

Our Certificate of Incorporation also provides that special meetings of our stockholders may be called only by the majority of our Board or by the chairman of our Board.

Advance Notice Requirements for Stockholder Proposals and Director Nominations

Our  Bylaws  provide  that  stockholders  seeking  to  bring  business  before  a  meeting  of  stockholders,  or  to  nominate  candidates  for  election  as  directors  at  a  meeting  of  stockholders,  must
provide us with timely written notice of their proposal. Our Bylaws also specify requirements as to the form and content of a stockholder’s notice. These provisions may preclude stockholders from
bringing matters before an annual meeting of stockholders or from making nominations for directors at an annual meeting of stockholders.

Amendment to our Certificate of Incorporation and Bylaws

Our Certificate of Incorporation may generally be amended by a majority of our stockholders, except with respect to provisions regarding our Board, stockholder meetings and amendments

to our Certificate of Incorporation and Bylaws, which may only be amended upon approval of holders of at least sixty six and two thirds percent (66-2/3%) of our outstanding

voting stock. In addition, the approval of at least eighty percent (80%) of our outstanding voting stock is required to amend the provisions of Article VI of our Certificate of Incorporation with respect
to limitation of director liability, indemnification of directors and officers and renunciation of corporate opportunities. Our Bylaws may generally be amended by our Board or by our stockholders
upon approval of holders of at least sixty six and two thirds percent (66-2/3%) of our outstanding voting stock.

Delaware Anti-Takeover Statute

We are subject to the provisions of Section 203 of the DGCL, an anti-takeover law. Subject to exceptions, the statute prohibits a publicly-held Delaware corporation from engaging in a

“business combination” with an “interested stockholder” for a period of three (3) years after the date of the transaction in which the person became an interested stockholder, unless:

•

•

•

prior to such date, the board of directors of the corporation approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder;

upon consummation of the transaction which resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least eighty-five percent (85%) of the voting
stock of the corporation outstanding at the time the transaction commenced (excluding for purposes of determining the number of shares outstanding, those shares owned by (1) persons who
are directors and also officers and (2) employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be
tendered in a tender or exchange offer); or

on  or  after  such  date,  the  business  combination  is  approved  by  the  board  of  directors  and  authorized  at  an  annual  or  special  meeting  of  stockholders  and  not  by  written  consent,  by  the
affirmative vote of at least sixty six and two thirds percent (66-2/3%) of the outstanding voting stock which is not owned by the interested stockholder.

For purposes of Section 203 of the DGCL, a “business combination” includes a merger, asset sale or other transaction resulting in a financial benefit to the interested stockholder, with an “interested
stockholder” being defined as a person who, together with affiliates and associates, owns, or within three (3) years prior to the date of determination whether the person is an “interested stockholder,”
did own, fifteen percent (15%) or more of the corporation’s voting stock. We expect the existence of this provision to have an anti-takeover effect with respect to transactions our Board does not
approve in advance.

Corporate Opportunities

Our  Certificate  of  Incorporation  provides  that  we  expressly  renounce  any  interest  or  expectancy  in  any  corporate  opportunity  and  that  there  shall  be  no  expectation  that  such  corporate
opportunity be offered to us or our affiliates, if such opportunity is one that an “Institutional Investor” (as defined below) has acquired knowledge of or is otherwise pursuing, such that as a result of
such renunciation, the corporate opportunity shall belong to such Institutional Investor. The renunciation does not apply to any interest or expectancy we may have in any corporate opportunity that is
expressly offered to any of our directors or officers in his or her capacity as a director or officer of us. An “Institutional Investor” is defined as (i) GaAs Labs, LLC and its affiliated companies, or (ii)
Summit Partners, L.P. and its affiliated companies, in each case including each of their respective directors, officers, employees and agents.

Exclusive Forum

Our Certificate of Incorporation and our Bylaws provide that the Court of Chancery of the State of Delaware shall be the sole and exclusive forum for (i) any derivative action or proceeding
brought on our behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed by any director or officer of our Company to us or our stockholders, (iii) any action asserting a claim against
us arising pursuant to the DGCL or our Certificate of Incorporation or our Bylaws or (iv) any action asserting a claim against us that is governed by the internal affairs doctrine. Although we have
included a choice of forum clause in our Certificate of Incorporation, it is possible that a court could rule that such clause is inapplicable or unenforceable. Our Bylaws provide that any person or
entity purchasing or otherwise acquiring an interest in our capital stock is deemed to have notice of and to have consented to the exclusive forum provisions described in this paragraph.

Our Bylaws further provide that any person or entity holding or otherwise acquiring an interest in our capital stock is deemed to have (i) consented and submitted to personal jurisdiction of
the courts located within the State of Delaware in connection with any action described in the paragraph above (an “Action”), (ii) waived any objection to the exercise of personal jurisdiction over
such stockholder in the courts located within the State of Delaware, (iii) waived any argument relating to the inconvenience of the forums described in (i) and (ii) of this paragraph with respect to any
Action, (iv) agreed not to commence any Action other than before a court within the State of Delaware nor to make any attempt to cause the

transfer or removal of any such Action to any court other than a court within the State of Delaware, and (v) consented to having service of process made upon such stockholder by service upon such
stockholder’s counsel as agent for such stockholder in the event that such stockholder brings an Action in a court other than a court within the State of Delaware.

Transfer Agent and Registrar

The transfer agent and registrar for our common stock is American Stock Transfer & Trust Company, LLC.

Listing

Our common stock is listed on the Nasdaq Global Select Market under the symbol “MTSI.”

MACOM TECHNOLOGY SOLUTIONS HOLDINGS, INC.
2012 OMNIBUS INCENTIVE PLAN - FRENCH SUB
RESTRICTED STOCK UNIT AWARD AGREEMENT FOR EMPLOYEES IN FRANCE

Pursuant to your Restricted Stock Unit Award Notice (the “Award Notice”) and this Restricted Stock Unit Award Agreement For Employees in France (this
“Agreement”), MACOM Technology Solutions Holdings, Inc. (the “Company”) has granted you a Restricted Stock Unit Award (the “Award”) under its 2012
Omnibus Incentive Plan, as amended and restated (the “Plan”) for the number of Time-Based Restricted Stock Units and the target number of Performance-Based
Restricted Stock Units indicated in your Award Notice. Capitalized terms not explicitly defined in this Agreement but defined in the Plan shall have the same
definitions as in the Plan.

The details of the Award are as follows:

1. Vesting and Settlement

The Award will vest and become payable according to the vesting schedule set forth in the Award Notice and Exhibit A thereto, as applicable (the “Vesting
Schedule”) by any case, the Restricted Stock Units will not vest before one year after the date of grant of the Award. One share of the Company’s Common Stock
will be issuable for each Restricted Stock Unit that vests and becomes payable. Restricted Stock Units that have vested and are no longer subject to forfeiture
according to the Vesting Schedule are referred to herein as “Vested Units.” Restricted Stock Units that have not vested and remain subject to forfeiture under the
Vesting Schedule are referred to herein as “Unvested Units.” The Unvested Units will vest (and to the extent so vested cease to be Unvested Units remaining subject
to forfeiture) and become payable in accordance with the Vesting Schedule (the Unvested and Vested Units are collectively referred to herein as

the “Units”). As soon as practicable, but in any event within 30 days, after Unvested Units become Vested Units subject to income tax withholdings (as outlined
below), the Company will settle the Vested Units by issuing to you one share of the Company’s Common Stock for each Vested Unit. The Award will terminate and
the Units will be subject to forfeiture upon your Termination of Service as set forth in Section 2.

2. Termination of Award upon Termination of Service

Unless the Plan Administrator determines otherwise prior to your Termination of Service, upon your Termination of Service any portion of the Award that has

not vested as provided in Section 1 will immediately terminate and all Unvested Units shall immediately be forfeited without payment of any further consideration to
you.

3. Securities Law Compliance

3.1 You represent and warrant that you (a) have been furnished with a copy of the Plan and all information which you deem necessary to evaluate the merits and

risks of receipt of the Award, (b) have had the opportunity to ask questions and receive answers concerning the information received about the Award and the
Company, and (c) have been given the opportunity to obtain any additional information you deem necessary to verify the accuracy of any information obtained
concerning the Award and the Company.

1

3.2 You hereby agree that you will in no event sell or distribute all or any part of the shares of the Company’s Common Stock that you receive pursuant to

settlement of this Award (the “Shares”) unless (a) there is an effective registration statement under the Securities Act and applicable state securities laws covering
any such transaction involving the Shares or (b) the Company receives an opinion of your legal counsel (concurred in by legal counsel for the Company) stating that
such transaction is exempt from registration or the Company otherwise satisfies itself that such transaction is exempt from registration by any case, the Shares cannot
be sold sooner than two years after the date of grant of the Restricted Stock Units in respect of which the Shares were issued. You understand that the Company has
no obligation to you to maintain any registration of the Shares with the SEC and has not represented to you that it will so maintain registration of the Shares.

3.3 You confirm that you have been advised, prior to your receipt of the Shares, that neither the offering of the Shares nor any offering materials have been

reviewed by any administrator under the Securities Act or any other applicable securities act (the “Acts”) and that the Shares cannot be resold unless they are
registered under the Acts or unless an exemption from such registration is available.

3.4 You hereby agree to indemnify the Company and hold it harmless from and against any loss, claim or liability, including attorneys’ fees or legal expenses,
incurred by the Company as a result of any breach by you of, or any inaccuracy in, any representation, warranty or statement made by you in this Agreement or the
breach by you of any terms or conditions of this Agreement.

4. Transfer Restrictions

Units shall not be sold, transferred, assigned, encumbered, pledged or otherwise disposed of, whether voluntarily or by operation of law.

5. No Rights as Stockholder

You shall not have voting or other rights as a stockholder of the Common Stock with respect to the Units.

6. Independent Tax Advice

You acknowledge that determining the actual tax consequences to you of receiving or disposing of the Units and Shares may be complicated. These tax
consequences will depend, in part, on your specific situation and may also depend on the resolution of currently uncertain tax law and other variables not within the
control of the Company. You are aware that you should consult a competent and independent tax advisor for a full understanding of the specific tax consequences to
you of receiving the Units and receiving or disposing of the Shares. Prior to executing this Agreement, you either have consulted with a competent tax advisor
independent of the Company to obtain tax advice concerning the receipt of the Units and the receipt or disposition of the Shares in light of your specific situation or
you have had the opportunity to consult with such a tax advisor but chose not to do so.

7. Withholding

Except for the social contribution provided for under Article L. 137-13 of the French social security code (Code de sécurité sociale), which is due by the

employer, you are ultimately responsible for all taxes arising in connection with this Award (e.g., at vesting and/or upon receipt of the Shares), including any
domestic or foreign tax withholding obligation required by law, whether national, federal, state or local, including FICA or any other social tax obligation (the “Tax

2

Withholding Obligation”), regardless of any action the Company or any Related Company takes with respect to any such Tax Withholding Obligation that arises in
connection with this Award. As a condition to the issuance of Shares pursuant to this Award, you will be required to satisfy the Tax Withholding Obligation that
arises upon receipt of the Shares or otherwise. The Company may refuse to issue any Shares to you until you satisfy the Tax Withholding Obligation.
Notwithstanding the forgoing, to the maximum extent permitted by law, you hereby grant the Company and any Related Company the right to deduct without notice

MACOM TECHNOLOGY SOLUTIONS HOLDINGS, INC.
2012 OMNIBUS INCENTIVE PLAN
RESTRICTED STOCK UNIT AWARD AGREEMENT FOR CANADIAN
PARTICIPANTS

Pursuant to your Restricted Stock Unit Award Notice (the "Award Notice") and this Restricted Stock Unit Award Agreement (this "Agreement"), MACOM

Technology Solutions Holdings, Inc. (the "Company") has granted you a Restricted Stock Unit Award (the "Award") on the terms and conditions set forth in this
Agreement and as otherwise provided under its 2012 Omnibus Incentive Plan (the "Plan") for the number of Restricted Stock Units indicated in your Award Notice.
Capitalized terms not explicitly defined in this Agreement but defined in the Plan shall have the same definitions as in the Plan.

The details of the Award are as follows:

1.

Vesting and Settlement

The Award will vest and become payable according to the vesting schedule set forth in the Award Notice (the "Vesting Schedule"). One share of the
Company's Common Stock will be issuable for each Restricted Stock Unit that vests and becomes payable. Restricted Stock Units that have vested and are no longer
subject to forfeiture according to the Vesting Schedule are referred to herein as "Vested Units." Restricted Stock Units that have not vested and remain subject to
forfeiture under the Vesting Schedule are referred to herein as "Unvested Units." The Unvested Units will vest (and to the extent so vested cease to be Unvested Units
remaining subject to forfeiture) and become payable in accordance with the Vesting Schedule (the Unvested and Vested Units are collectively referred to herein as the
"Units"). As soon as practicable after Unvested Units become Vested Units and, subject to the Participant’s satisfaction of income tax withholdings (as outlined
below), the Company will settle the Vested Units by issuing to you one share of the Company's Common Stock for each Vested Unit. The Award will terminate and
the Units will be subject to forfeiture upon your Termination of Service as set forth in Section 2.

2.     Termination of Award upon Termination of Service

Unless the Plan Administrator determines otherwise prior to your Termination of Service, upon your Termination of Service any portion of the Award that has
not vested as provided in Section 1 will immediately terminate and all Unvested Units shall immediately be forfeited without payment of any further consideration to
you. With respect to the Plan and this Agreement only, and for greater certainty, Termination of Service of a Canadian Participant shall be such Participant’s last day
of active employment with, or service to, the Company or any of its Affiliates, regardless of whether such termination occurs with or without any or adequate
reasonable notice, or with or without any or adequate compensation in lieu of such reasonable notice, and does not include any period of statutory, contractual,
common law or other reasonable notice of termination of employment or any period of salary continuance or deemed employment.

3.     Securities Law Compliance

3.1 You represent and warrant that you (a) have been furnished with a copy of the Plan and all information which you deem necessary to evaluate the merits

and risks of receipt of the Award, (b) have had the opportunity to ask questions and receive answers concerning the information

1

received about the Award and the Company, (c) have been given the opportunity to obtain any additional information you deem necessary to verify the accuracy of
any information obtained concerning the Award and the Company, and (d) agree to be bound by all the terms and provisions of the Plan.

3.2 You hereby agree that you will in no event sell or distribute all or any part of

the shares of the Company's Common Stock that you receive pursuant to settlement of this Award (the "Shares") unless (a) there is an effective registration statement
under the Securities Act and applicable state securities laws covering any such transaction involving the Shares or (b) the Company receives an opinion of your legal
counsel (concurred in by legal counsel for the Company) stating that such transaction is exempt from registration or the Company otherwise satisfies itself that such
transaction is exempt from registration. You understand that the Company has no obligation to you to maintain any registration of the Shares with the SEC and has
not represented to you that it will so maintain registration of the Shares.

3.3 You confirm that you have been advised, prior to your receipt of the Shares, that neither the offering of the Shares nor any offering materials have been

reviewed by any administrator under the Securities Act or any other applicable securities act (the "Acts") and that the Shares cannot be resold unless they are
registered under the Acts or unless an exemption from such registration is available.

3.4 You hereby agree to indemnify the Company and hold it harmless from and

against any loss, claim or liability, including attorneys' fees or legal expenses, incurred by the Company as a result of any breach by you of, or any inaccuracy in, any
representation, warranty or statement made by you in this Agreement or the breach by you of any terms or conditions of this Agreement or the Plan.

4.     Transfer Restrictions

Units shall not be sold, transferred, gifted, assigned, encumbered, pledged, hypothecated or otherwise disposed of, whether voluntarily or involuntarily by

operation of law.

5.     No Rights as Stockholder

You shall not have voting or other rights as a stockholder of the Common Stock with respect to the Units.

6.    Independent Tax Advice

You acknowledge that determining the actual tax consequences to you of receiving, holding or disposing of the Units and Shares may be complicated. These
tax consequences will depend, in part, on your specific situation and may also depend on the resolution of currently uncertain tax law and other variables not within
the control of the Company. You are aware that you should consult a competent and independent tax advisor for a full understanding of the specific tax consequences
to you of receiving, holding or disposing of the Units and receiving, holding or disposing of the Shares. Prior to executing this Agreement, you either have consulted
with a competent tax advisor independent of the Company to obtain tax advice concerning the receipt, holding or disposition of the Units and the receipt, holding or
disposition of the Shares in light of your specific situation or you have had the opportunity to consult with such a tax advisor but chose not to do so. You
acknowledge that you have satisfied yourself in relation to all tax matters relevant to the acquisition, holding and

2

disposition of Units and Shares in connection with the Plan. It is your responsibility to complete and file any tax returns in respect of your participation in the Plan.
The Company shall not be responsible for any tax consequences to you in connection with your participation in the Plan.

7. Clawback

By accepting this Award, you acknowledge and agree that this Award and all other awards granted to you under the Plan, any shares issued in respect thereof,

and any proceeds and other amounts received in respect of this Award, other awards or such shares are subject to forfeiture and repayment (i) under the Company’s
Compensation Recoupment Policy, as from time to time amended and in effect; (ii) under any other policy of, or agreement with, the Company or any Related
Company that is applicable to you and that provides for the cancellation, forfeiture, disgorgement, repayment or clawback of incentive compensation; and (iii) to the
extent required by law or applicable stock exchange listing standards, including, without limitation, Section 10D of the Exchange Act. A copy of the Company’s
Compensation Recoupment Policy as in effect on the date of this Agreement has been provided to you, which you acknowledge and agree is subject to amendment
and/or amendment and restatement from time to time.

8.     Withholding

You are ultimately responsible for all taxes arising in connection with this Award (e.g., at vesting or disposition and/or upon receipt of the Shares), including
any domestic or foreign tax withholding obligation required by law, whether national, federal, state or local, including all applicable social security charges (the "Tax
Withholding Obligation"), regardless of any action the Company or any Related Company takes with respect to any such Tax Withholding Obligation that arises in
connection with this Award. As a condition to the issuance of Shares pursuant to this Award, you will be required to satisfy the pay to the Company an amount as
necessary, so as to ensure the Company is in compliance with any applicable Tax Withholding Obligation that arises in connection with such issuance and upon
receipt of the Shares or otherwise by the Participant. The Company may refuse to issue any Shares to you until you satisfy the Tax Withholding Obligation. Without
limiting the generality of the foregoing and notwithstanding any other mechanism for payment of the Tax Withholding Obligation detailed in the Plan. unless the
Participant has made arrangements with the Company to remit the amount of such Tax Withholding Obligation arising, the Company will withhold from the shares
otherwise payable to you with respect to your Vested Units the number of whole shares of the Company's common stock required to satisfy the minimum applicable
Tax Withholding Obligation, the number to be determined by the Company based on the Fair Market Value of the Company's Common Stock on the date the
Company is required to withhold. Notwithstanding the forgoing, to the maximum extent permitted by law, you hereby grant the Company and any Related Company
the right to deduct without notice from salary or other amounts payable to you, an amount sufficient to satisfy the Tax Withholding Obligation.

9.     General Provisions

9.1 Assignment. The Company may assign its forfeiture rights at any time, whether or not such rights are then exercisable, to any person or entity selected by

the Company's Board of Directors.

9.2 No Waiver. No waiver of any provision of this Agreement will be valid unless in writing and signed by the person against whom such waiver is sought to

be enforced, nor will failure to

3

enforce any right hereunder constitute a continuing waiver of the same or a waiver of any other right hereunder.

9.3 Undertaking. You hereby agree to take whatever additional action and execute whatever additional documents the Company may deem necessary or
advisable in order to carry out or effect one or more of the obligations or restrictions imposed on either you or the Units pursuant to the express provisions of this
Agreement.

9.4 Successors and Assigns. The provisions of this Agreement will inure to the benefit of, and be binding on, the Company and its successors and assigns

and you and your legal representatives, heirs, legatees, distributees, assigns and transferees by operation of law, whether or not any such person will have become a
party to this Agreement and agreed in writing to join herein and be bound by the terms and conditions hereof.

9.5 No Employment or Service Contract. Nothing in this Agreement will affect in any manner whatsoever the right or power of the Company, or a Related

liability whatsoever (whether in contract, tort, or otherwise howsoever) in connection with:

(a) the loss of your Award(s) under the Plan

(b) the loss of your eligibility to be granted Award(s) under the Plan; and/or

(c) the manner in which any power or discretion under the Plan is exercised or the failure or refusal of any person to exercise any power or discretion under

the Plan.

9.7 Relationship to the Plan. This Agreement will be deemed to incorporate by reference the terms and conditions of the Plan. In the event of any

inconsistency between the provisions of the Plan and the provisions of this Agreement, the inconsistency will be resolved by giving priority to the terms of this
Agreement.

form, of your personal data as described in this Agreement by and among, as applicable, the Company and any Related Company for the exclusive purpose of

or the Award, or would disqualify the Plan or Award under any laws deemed applicable by the Committee, such provision shall be construed or deemed amended to
conform to the applicable laws, or if it cannot be construed or deemed amended without, in the determination of the Committee, materially altering the intent of the
