Overview of Our Business

PART I

Axcelis Technologies, Inc. (‘‘Axcelis,’’  the ‘‘Company,’’ ‘‘we,’’ ‘‘us,’’ or ‘‘our’’) designs, manufactures

and services ion implantation, dry strip  and other processing equipment used in the fabrication of
semiconductor chips. We sell to leading  semiconductor chip manufacturers worldwide. The ion
implantation business comprised approximately 74.5% of  our revenue in  2011 with the  remaining  25.5%
of revenue derived from our dry strip  and other processing systems.  In addition to equipment,  we
provide extensive aftermarket service  and  support, including spare parts,  equipment upgrades,
maintenance services and customer training.

Axcelis, which was incorporated in Delaware in 1995, is headquartered in Beverly, Massachusetts.

We  maintain an Internet site at http://www.axcelis.com. We make available free  of  charge on and
through this website our annual reports on Form 10-K,  quarterly reports  on Form 10-Q, current reports
on Form 8-K, and amendments to those reports filed  or furnished  pursuant to Section 13(a) or  15(d) of
the Exchange Act as soon as reasonably practicable after we  electronically file such material with, or
furnish it to, the Securities and Exchange Commission.  Our website and the information contained
therein or connected thereto shall not be deemed to be incorporated into  this Form  10-K.

Industry Overview

Semiconductor chips, also known as integrated  circuits, are  used  in personal computers,

telecommunication equipment, digital consumer electronics,  wireless communication  products and other
applications. Types of semiconductor  chips include memory chips (which  store and  retrieve
information), microprocessors (logic devices which process  information) and ‘‘system on chip’’ devices
(which have both logic and memory features). Most  semiconductor  chips are built  on a wafer of silicon
of either 200mm (8 inches) or 300mm (12 inches) in diameter. Each semiconductor  chip is made up  of
millions of tiny transistors or ‘‘switches’’  to control the  functions of the  device. Transistors are created
in the silicon wafer by introducing various precisely placed impurities into  the silicon in specific
patterns. The process steps in the formation of transistors are  traditionally referred to as
‘‘front-end-of-line.’’ The ‘‘back-end-of-line’’ process steps  connect the transistors and other components
together through several overlapping  layers of  metal wires, known  as interconnect, creating a complete
circuit. Each layer of metal interconnect  must be separated  by a non-conductive or insulating material
called inter-level dielectric. Each layer  that is added is selectively patterned to all previous  layers
through a process called photolithography.

Semiconductor chip manufacturers utilize many different types of equipment  in the making  of
integrated circuits. Over 300 process  steps utilizing over 50  different  types of process tools are required
to make a single device like a microprocessor.  Semiconductor chip manufacturers seek efficiency
improvements through increased throughput, equipment  utilization and  higher manufacturing yields.
Capacity is added by increasing the amount of manufacturing equipment in  existing fabrication  facilities
and by constructing new fabrication facilities. Periodically the semiconductor industry adopts a larger
silicon wafer size to achieve lower manufacturing costs. Semiconductor  manufacturers  can produce
more chips on a larger wafer, thus reducing  the overall manufacturing cost per chip.  For example,  the
use of 200mm wafers in production began at  the end of the  1980s. The migration from 200mm to
300mm began at the end of the 1990s. The majority  of wafer fabrication facilities today are  using
wafers with a diameter of 300mm. In  2011, Axcelis derived  75.1%  of  total systems  revenue (a
component of product revenue) from sales of 300mm  equipment. In  2011, industry participants began
planning for the next wafer size transition, to 450mm  diameter wafers. The schedule for  this future
transition will vary by customer.

1

The customer base is also changing. Given the magnitude  of the investment needed to build  a new

wafer fabrication facility (often referred to as a ‘‘fab’’), which  can be over  $4 billion  for a  new 300mm
fab, many customers are entering into partnerships to offset  the cost of technology development  and
manufacturing. In addition, many chip  developers outsource all or part of their chip  manufacturing
requirements to contract manufacturers,  known as foundries.  Foundries are  significant purchasers of
semiconductor manufacturing equipment.

The semiconductor industry is highly cyclical,  as global chip production capacities successively
exceed, then lag behind, global chip demand. When chip  demand is high, and inventories low,  chip
manufacturers add capacity though capital equipment purchases. Given the difficulties of forecasting
and calibrating chip demand and production capacity, the industry periodically  experiences excess chip
inventories and softening chip prices.  Our customers react with muted capital spending, lowering the
demand for our equipment. Changes  in  consumer and  business  demand for  products in  which chips are
used also affect the industry. A successful semiconductor equipment manufacturer must not only
provide some of the most technically complex products manufactured  in the world  but also  must  design
its  business to thrive during the inevitable  low points  in the cycle.

After historic lows in 2009, the market for  our  products steadily improved during 2010  and we

gained market share with our single wafer  ion implant systems for high current and  high energy
applications (the Optima HDx and Optima  XEx). This market  recovery continued during the  first  half
of 2011, but during the second half of 2011,  deterioration within  the industry environment decreased
our  revenues as compared with the first half of the year. In addition, we had  delays in key penetrations
in the second half of 2011. These delays were a function of poor market conditions and issues in our
prioritization of new technology. The Company’s 2011 results reflect efforts in recent  years  to  lower our
breakeven revenue levels to avoid significant losses in a downturn.

Axcelis’ Strategy

Our mission and vision is to:

(cid:129) Ensure our customers’ success by providing enabling semiconductor  manufacturing and support

solutions that deliver the best performance at  the lowest total cost of ownership.

(cid:129) Achieve and maintain market share leadership in ion  implantation and  dry  strip.

(cid:129) Deliver profitability and positive cash flow through the industry cycles to maximize shareholder

and employee value.

Operationally, we manage our business based on three  main tenets:

(cid:129) technology leadership,

(cid:129) operational excellence, and

(cid:129) customer partnerships.

We  have continued to invest in research and development through  the industry cycles to assure our

products meet the needs of our customers.  We take pride  in our  scientists and engineers  who continue
to add  to our portfolio of patents and  unpatented proprietary technology  to ensure  that  our investment
in technology leadership is translated into unique  product advantages. We strive for operational
excellence by focusing on ways to lower  our manufacturing  and design costs  and to improve  our
delivery times to our customers. Finally, we have improved our customer support infrastructure and
have established Global Customer Teams  and a  focused account management  structure to strengthen
our  customer relationships and increase customer satisfaction.

2

Although the Company continues to  focus on  equipment for  the semiconductor  manufacturing
industry, we have and will continue to explore,  from time  to  time,  ways to utilize our existing products
in alternative markets such as solar and  LED  (Light-Emitting Diodes).

Ion Implantation Systems

Ion implantation is a principal step in the transistor formation cycle  of the semiconductor

manufacturing process. An ion implanter  is  a large, technically  advanced machine that injects dopants
such as arsenic, boron or phosphorus into a silicon wafer. These dopants  are ionized and therefore
have electric charges. With an electric  charge they can be manipulated, moved and accelerated with
electric and magnetic fields. Ion implanters use  these fields to create a beam of ions  with a precisely
defined amount of energy (ranging between several  hundred and three million electron-volts) and with
a precisely defined amount of beam current (ranging from  microamps  to  milliamps).  Certain areas of
the silicon wafer are blocked off by a polymer material known as  photoresist, which  acts  as a ‘‘stencil’’
to pattern devices so that the dopants  will only enter the wafer where needed.  The dopants change the
electrical properties of the silicon wafer  to create the active components of  a chip, called the
transistors. Typical process flows require twenty implant steps, with  the most  advanced processes
requiring thirty or more. Each implant  step is  characterized by  four key parameters: dopant type, dose
(amount of dopant), energy (depth into  the silicon)  and tilt (angle  of  wafer  relative to the  ion beam).

In order to cover the wide range of implant steps,  three different types of  implanters have  been

developed, each designed to cover a specific range of  applications, primarily  defined by dose and
energy. The three traditional implanter types are referred to as medium current, high current and  high
energy:

(cid:129) Medium current (mid dose) implanters  are the original model of  ion implanter, with mid to

low-range energy and dose capability. These implanters are single wafer systems  in which  only
one wafer at a time is slowly moved in  front of the ion beam.

(cid:129) High current (high dose) implanters were the second type of  implanter to emerge, having low

energy capability and high dose range. High current  implanters were initially designed  as ‘‘multi
wafer’’ or ‘‘batch’’ tools for maximum  productivity, processing multiple  wafers  at the same time.
To address smaller device geometries and provide high tilt, single wafer high current  implanters
now dominate the sector.

(cid:129) High energy implanters emerged to address  the need for deeper implants  with a high  energy

range and low dose. High energy implanters are available in both multi wafer and single wafer
architectures.

Axcelis offers a complete line of high energy, high current and medium current  implanters for all

application requirements.

(cid:129) High Energy Implant. Axcelis is a market leader in high energy ion  implanters. Our  single wafer

tool for high energy applications is the Optima XEx.  The Optima  XEx combines  Axcelis’
production-proven RF Linac high energy, spot beam  technology with  a high-speed,
state-of-the-art single wafer endstation, enabling unmatched throughput.  Axcelis’ advanced spot
beam ensures that all points across the  wafer see the same beam  at  the same beam  angle,
resulting in exceptional process control and maximum  yield. We expect to maintain our
leadership in the high energy segment through sales of our multi wafer high  energy systems and
the Optima XEx.

(cid:129) High Current Implant. Our single wafer product for high current  applications is the Optima
HDx. We use the term ‘‘high dose’’ or ‘‘HD’’ in connection with this product because the
Optima HDx fulfills all traditional high  current requirements while  extending beyond traditional
high current energy and dose ranges. In order to maximize utilization and flexibility, the Optima

3

HDx can process some traditional mid current implants. In  addition, the  Optima HDx is
extendable into ultra-low energy applications to satisfy future process  requirements including
leakage current performance.

(cid:129) Medium Current Implant. Axcelis  re-entered the medium current  market  segment with a new

product, the Optima MDxt, in 2011, a market in which we had not previously had  a competitive
offering. We refer to this product as  ‘‘mid dose’’  or ‘‘MD’’ because it  has energy and  dose
capabilities which extend beyond the traditional medium current  space  into traditional  high
current and high energy spaces. Axcelis has  continued  to  develop medium current technology
and has plans to introduce next generation products in the  future.

We  believe the Optima products will  continue to meet  customer demand  for advantages in

productivity, simplicity, process performance  and  technical  extendibility.

Dry Strip

In the process steps prior to ion implantation, a light sensitive, polymer-based liquid  called

photoresist is spread in a uniformly thin film on the wafer. Through a process known as
photolithography, the photoresist is developed into  a pattern  like a stencil. Once the  subsequent
implant processes and etch steps (in  which the  top layer of the surface  of  the wafer  not  covered by
photoresist is removed) are completed, the photoresist is no longer necessary  and must be removed.
The primary means of removing photoresist  and  residue  is a process called  ‘‘dry  strip’’  or ‘‘ashing.’’ Our
dry strip machines, also called ‘‘ashers,’’  use microwave and radio  frequency energy to turn process
gases into plasma,  which then acts to  ‘‘clean’’ the surface of  the  wafer  by removing the  photoresist and
unwanted residue.

Axcelis offers a full line of dry strip tools  that cover the entire  range of customer applications. Our
most advanced products, the Integra RS  and  ES, bring significantly  higher productivity and flexibility to
Axcelis’ already proven advanced dry strip process capabilities. The Integra’s  unique multi-chamber
design includes paired-chamber process modules  that  can run production recipes with  the highest
throughputs available for leading edge  memory and logic devices. Each  of  the chamber pairs can
operate independently, giving users the  choice of running different cleaning recipes simultaneously  or
performing maintenance on one module  while the others  continue to operate. This flexiblity makes the
system ideal for a variety of advanced cleaning applications in a high volume manufacturing
environment. The  platform also includes  technology  required to address cleaning challenges  at
emerging transistor device nodes, such  as those associated with advanced source/drain formation and
high-k/metal-gate structures.

We  believe our dry strip products and technology will continue  to  meet customer demand  for

advantages in productivity, process performance  and  technical  extendibility.

Aftermarket Support and Services

We  offer our customers extensive aftermarket service and support  throughout the  lifecycle  of  the

equipment we manufacture as well as  equipment we previously  manufactured.  We believe that
approximately 3,000 of our products are in  use in  32 countries worldwide. The service and support  that
we provide include spare parts, equipment upgrades, and maintenance services. We provide  service  out
of 32  field offices to customers located in 32 countries.  Revenue generated  through our  service  and
support business represented about 46.2%, 51.7%, and 73.8% of revenue in  2011, 2010, and 2009,
respectively.

To support our aftermarket business  we  have several  hundred staff members,  including sales and

marketing personnel, field service engineers, and spare parts and applications engineers, as well as
employees located at our manufacturing  facilities  who work with  our customers to provide  customer
training and documentation, product, process and applications support. In 2011,  Applied Materials,  Inc.

4

provided aftermarket services and support  services for  our products in Japan. This role will  be
transitioned to Ulvac Techno, a Japanese company, in  2012.

Most of our customers maintain spare parts  inventories for our  machines.  In  addition to our

web-based spare parts management and  replenishment tracking  program, we offer a number of
Business-to-Business options to support our  customers’  parts  management requirements.  Our Axcelis
Managed Inventory service offering, a parts consignment arrangement, provides the customer with  full
spares support, with Axcelis retaining responsibility for the complete supply  chain. The expansion of
these services provides ease of use alternatives that  help  us reduce order fulfillment costs and  improve
cycle time, resulting in an expanded customer base for this service offering.

Sales and Marketing

We  primarily sell our equipment and  services through our direct sales  force. We have 11  sales
offices in 7 countries. Aftermarket service  and  support  is also  offered  at all of these offices. In the
United States, we conduct sales and marketing activities from two locations.  Outside of the  United
States, our sales offices are located in  Taiwan, South Korea, China, Germany, Singapore and Italy. In
addition, isolated sales are made in smaller  markets  through distributors and manufacturing
representatives.

Since March 2009, SEN Corporation, or ‘‘SEN’’ (our  former Japanese  joint venture, which was

divested in 2009), has held a non-exclusive license to use  certain patented and  unpatented technology
associated with legacy products owned  by the Company.  Axcelis benefits  from a reciprocal  license of
implant technology from SEN. These royalty-free, perpetual cross  licenses do not restrict our  ability to
sell any of our products in Japan or elsewhere  in the world. See Note 17 to our Consolidated Financial
Statements contained in Item 15 of this  Annual  Report  on Form 10-K for further information
regarding SEN.

International revenue, including export sales from  our  U.S.  manufacturing facilities to foreign

customers, sales by foreign subsidiaries and branches, and royalties, accounted for  72.3% of total
revenue in 2011, 75.8% in 2010, and 62.8% in 2009. Substantially  all of our sales  are denominated in
U.S. dollars. See Note 15 to our Consolidated  Financial Statements contained in Item  15 of this
Form 10-K for a breakdown of our revenue and long-lived assets in  the United States,  Europe and
Asia.

Customers

In 2011, the top 20 semiconductor manufacturers accounted for  approximately 84.6%  of  total

semiconductor industry capital spending,  up from 78.9%  in 2010.  These manufacturers are  from the
four  largest semiconductor manufacturing  regions in the world: the United States, Asia  Pacific (Taiwan,
South Korea, Singapore, and China),  Japan  and Europe. The Company  serves  all  leading
semiconductor manufacturers.

Revenue from our ten largest customers  accounted  for 68.6%, 62.7%, and 56.6% of  revenue in
2011, 2010, and 2009, respectively. We  expect that  sales of our products to relatively few customers will
continue to account for a high percentage of revenue for the foreseeable future.  In 2011, one customer
accounted for 21.2% of revenue. In 2010, one  customer accounted for  18.6% of revenue.  In 2009 no
customer accounted for more than 10% of revenue.

Our Beverly, Massachusetts Advanced Technology Center houses a process development  laboratory
with 12,500 sq. ft. of class 10/100/1000 clean room for product  demonstrations  and process development
and a 34,000 sq. ft. customer training center.  The Advanced Technology Center provides  infrastructure
and process capabilities that allow customers to test  their unique process steps  on our systems  under
conditions that substantially replicate the customers’ production environment.  This facility also  provides
significant capability for our research  and development efforts.

5

Research and Development

Our industry continues to experience rapid technological change, requiring us to frequently
introduce new products and enhancements.  Our ability to remain competitive in this  market  will
depend  in part upon our ability to develop new and enhanced systems and to introduce these systems
at competitive prices on a timely and cost effective  basis.

We  devote a significant portion of our  personnel and financial  resources to  research  and
development programs and seek to maintain close relationships with  our  customers to remain
responsive to their product needs. We have  also sought to reduce the  development cycle for  new
products through a collaborative process  whereby our engineering, manufacturing  and marketing
personnel work closely together with  one  another and with our customers at  an earlier stage in the
process. We  also use 3D, computer-aided design,  finite element analysis and  other  computer-based
modeling methods to test new designs.

Our expenditures for research and development were $47.2 million, $39.5 million and $32.7 million

in 2011, 2010, and  2009, respectively, or 14.8%, 14.4%  and  24.6%  of  revenue,  respectively. We  expect
that research and development expenditures  will continue to represent a substantial investment in
future years.

Manufacturing

We  manufacture products at our 417,000 sq. ft.  ISO 9000:2008, ISO 14001:2004 certified plant in

Beverly, Massachusetts. Our facility employs best  in class  manufacturing techniques  including lean
manufacturing, six sigma controls and  advanced inventory management, purchasing and  quality systems.
Our clean manufacturing process uses  class 1000/10,000 space to facilitate  most of our manufacturing
requirements.

The Company’s core manufacturing competency  is built around system  assembly and  test which
remains an in house capability due to  the high  degree  of expertise and intellectual property associated
with the process and design. Non-core work is sourced to one  of several global  partners  and includes
items such as power distribution, vacuum systems, wafer handling  and  commodity level  components. We
continuously pursue outsourcing opportunities  where the  economics are justified,  with a goal of
enabling factory capacity, quality and margin improvement. Our  supply chain  team is  globally focused
and is located in Beverly and Singapore.  Customized  and  commercially available software solutions
drive our planning, purchasing and inventory tracking process.

Our products are designed to be assembled and tested in a  modular fashion, which  facilitates our

industry-recognized ‘‘ship-from-cell’’ process. Specially  developed  test stands,  software and tooling
provide the framework for this accelerated delivery process. Customers that  choose  ship-from-cell
substantially improve their delivery times  while  receiving  the same high  level of quality provided by
more traditional longer cycle integration techniques. Product margins and inventory turns  also improve
as a result of shorter factory cycle times  and  increased labor  productivity.

Installation of our equipment is provided by  factory  and  field teams. The process includes placing
and leveling the equipment at its installation site, connecting it  to  sources  of gas, water  and electricity
and recalibrating it to specifications that  had previously been  met  during  factory testing.

Competition

The semiconductor wafer fabrication equipment market is highly  competitive  and is characterized
by a small number of medium to large size participants. We compete  in two  principal product markets
of the semiconductor wafer fabrication process:  ion implantation and dry strip. Significant competitive
factors in the semiconductor equipment  market include price, cost of ownership, equipment

6

performance, customer support, breadth of product  line, distribution  and financial viability.
Relationships also have a significant influence on a customer’s  choice of equipment supplier.

Ion Implantation.

In ion implantation, we compete against Varian Semiconductor Equipment

Associates, Inc. (acquired by Applied Materials, Inc.  in late 2011), SEN, Nissin Electric Co.,  Ltd.  and
Advanced Ion Beam Technology, Inc.

Dry  Strip. Our principal competitors in the dry strip  product market are PSK, Inc., Mattson

Technology Inc. and Novellus Systems, Inc.

Intellectual Property

We  rely on patent, copyright, trademark and trade  secret  protection, as  well as contractual
restrictions, in the United States and in  other countries  to  protect our  proprietary  rights in  our
products and our business. As of January 1,  2012, we  had 377  patents issued in the United States and
469 patents granted in other countries, as  well as  719 patent applications (72 in the  United States and
647 in other countries) on file with various  patent  agencies worldwide.  Patents are generally in effect
for up to 20 years from the filing of the application.

We  intend to file additional patent applications and grow  our  intellectual  property  portfolio  as

appropriate. Although patents are important to our  business,  we do not believe  that  we are
substantially dependent on any single patent  or any  group of patents.

We  have trademarks, both registered  and  unregistered, that  are  maintained to provide customer

recognition for our products in the marketplace.

From time to time, we enter into license agreements with  third parties under which we  obtain  or

grant rights to patented or proprietary  technology. Except for our license  agreement with SEN
(described above under ‘‘Sales and Marketing’’), we do not believe that any  of  our  licenses are
currently material  to us.

We  can give no assurance that we, our licensors, licensees,  customers or suppliers will  not  be
subject to claims of patent infringement or claims to invalidate our patents, or  that  any such claims will
not be successful, requiring us to pay substantial damages or remove certain  features from our products
or both.

Backlog

As of December 31, 2011, our systems backlog (excluding deferred systems revenue) was
$10.8 million, as compared to $51.7 million as of  December 31,  2010. Systems backlog including
deferred systems revenue was $23.1 million and $68.0 million as of  December 31,  2011 and  2010,
respectively. The decrease in backlog is  indicative of the overall  trend toward  slowdown in the
semiconductor equipment market during the second half of 2011. We believe  it is meaningful to
investors to include deferred systems revenue  as part of our backlog. Deferred systems  revenue
represents revenue that will be recognized in  future periods based on prior  shipments. Our policy  is to
include in backlog only those system orders for  which we have accepted purchase  orders  and typically
are due to ship within six months. Backlog does not include orders received for our  service  business
(spare parts, consumables and service contracts) due to the turn  rate associated with that business.
Generally, orders for services or parts  received during the quarter  are performed or shipped  within the
same quarter. All orders are subject to  cancellations or rescheduling by  customers with limited or  no
penalties. Due to possible changes in system delivery  schedules, cancellations  of  orders,  and delays in
systems shipments, our backlog at any particular  date is  not necessarily indicative of our actual  sales for
any succeeding period. In addition, our  backlog at  the beginning of a quarter typically  does not include
all orders required to achieve our sales objectives  for that quarter and  is not a reliable indicator of our
future sales.

7

Employees

As of December 31, 2011, we had 1,025  employees and 22 temporary  staff worldwide, of which 784

work in North America, 203 in Asia  and 60  in Europe. We consider our  relationship with  our
employees to be good. Our employees  are not represented by a  labor union and  are not subject to a
collective bargaining agreement. One of  our European locations has formed a  work council, which  has
certain information and discussion rights  under applicable law.

Environmental

We  are subject to environmental laws and regulations in the  countries in which we operate that

regulate, among other things: air emissions; water discharges; and the generation, use, storage,
transportation, handling and disposal of  solid  and hazardous  wastes produced  by  our  manufacturing,
research and development and sales activities. As with other companies engaged in  like businesses,  the
nature of our operations exposes us to  the risk of environmental liabilities, claims, penalties and orders.
We  believe, however, that our operations are  in substantial compliance with applicable  environmental
laws and regulations and that there are no pending environmental  matters  that  would have a  material
impact on our business. We are ISO-14001 certified at our Beverly,  MA facility.

Item 1A. Risk Factors.

Risks Related to Our Business and Industry

Set forth below and elsewhere in this Form 10-K and in other documents we file with  the SEC are
risks and uncertainties that could cause actual results to differ materially  from the results  contemplated
by the forward-looking statements contained  in this Form 10-K. We  note that factors set forth below,
individually or in the aggregate, may cause  our  actual results  to  differ  materially from expected and
historical results. We note these factors  for investors as permitted by  the  Private  Securities  Litigation
Reform Act of 1995. You should understand  that it is not possible to predict or identify all such factors.
Consequently, you should not consider the  following  to  be  a complete discussion  of  all  potential risks
or uncertainties.

If we fail to develop and introduce reliable new or  enhanced products and services that meet the  needs  of
semiconductor manufacturers, our results will suffer.

Rapid  technological changes in semiconductor manufacturing processes require  us  to  respond
quickly to changing customer requirements. Our future success will depend in part upon  our  ability  to
develop, manufacture and successfully  introduce new systems and product  lines with improved
capabilities and to continue to enhance existing products. This will  depend upon a variety of factors,
including new product selection, timely  and  efficient completion of product  design and development
and of manufacturing and assembly processes, product performance in the field and effective sales and
marketing. In particular:

(cid:129) We must develop the technical specifications of  competitive new systems, or enhancements to
our  existing systems, and manufacture  and  ship these systems  or  enhancements in  volume in  a
timely manner.

(cid:129) We will need to accurately predict the  schedule  on which our customers  will be ready to

transition to new products, in order to accurately forecast demand  for new products  while
managing the transition from older products.

(cid:129) We will need to effectively manage  product reliability or quality problems that often exist  with

new systems, in order to avoid reduced orders, higher manufacturing costs, delays  in acceptance
and payment and additional service and warranty expenses.

(cid:129) Our new products must be accepted in the marketplace.

Our failure to meet any of these requirements will  have a material  adverse effect  on our operating

results and profitability.

We may  be unable to obtain needed additional capital to  finance our operations.

Our capital requirements may vary widely from quarter to  quarter, depending on, among other

things, capital expenditures, fluctuations in our operating results,  financing  activities, acquisitions and
investments and inventory and receivables management. We  believe that  our existing cash  and cash

9

equivalents will be sufficient to satisfy  our  anticipated cash requirements through the end  of 2012 and
beyond, but this, of course, depends on the accuracy of our assumptions about  levels of  sales and
expenses. A number of factors, including  those described in  these  ‘‘Risk Factors,’’ could prove our
assumptions wrong and cause us to require  additional capital  from  external sources. Depending on
market conditions, future debt or equity  financings may  not  be  possible on attractive terms  or at  all.  In
addition, future debt or equity financings could be dilutive  to  the existing holders  of our  common stock.

If semiconductor manufacturers do not make  sufficient capital expenditures, our sales and  profitability will be
harmed.

Almost all of our new orders will depend upon demand  from semiconductor  manufacturers  who
build or  expand fabrication facilities. When the rate of construction or  expansion of fabrication  facilities
declines, demand for our systems will  decline, reducing our revenue. Revenue decline also  hurts our
profitability because our fixed cost structure  and  our continued  investments in engineering,  research
and development and marketing necessary to develop new products and  to maintain extensive customer
service and support capabilities limit our  ability to reduce expenses in proportion to declining  sales.

Our financial results may fluctuate significantly.

We  derive most of our revenue from the sale of a relatively  small number of expensive products to
a small  number of customers. The list prices  on these products range from  $0.2 million to $5.0 million.
At our current sales level, each sale,  or  failure  to  make  a sale,  has a material effect on us in a
particular quarter. In a given quarter, a number  of factors can adversely  affect our revenue  and results,
including changes in our product mix,  increased fixed expenses per unit due to reductions in  the
number of products manufactured, and  higher fixed costs due to increased  levels of  research  and
development and expansion of our worldwide sales and marketing organization. Our financial results
also fluctuate based on gross profit realized on  sales. A variety of factors  may cause  gross profit as a
percentage of revenue to vary, including the mix and average  selling prices  of  products sold,  costs to
manufacture and customize systems and  warranty costs.  New product  introductions may also  affect our
gross  margins. Fluctuations in our financial results  may have an  adverse effect on the  price of our
common stock.

Our financial results may fall short of anticipated  levels; forecasting revenue and profitability is  complex  and
may be inaccurate.

Management may from time to time  provide financial forecasts. These forecasts are  based on
assumptions, believed to be reasonable when made, of shipment timing  and contract terms.  However, in
some cases, the final customer terms may not have been agreed  and documented  at the time the
forecast is made, so the level of revenue  recognizable in a particular quarter may vary from the
forecast. Our lengthy sales cycle, coupled  with customers’ competing capital budget  considerations,
make the timing of customer orders uneven and difficult to predict. In addition, our  backlog at the
beginning of a quarter typically does not  include all orders required to achieve our sales objectives for
that quarter and is not a reliable indicator  of our future  sales.  As a result, our  revenue and operating
results for a quarter depend on our shipping orders as  scheduled during that quarter, receiving
customer acceptance of shipped products  during the quarter, and obtaining new  orders  for products to
be shipped in that same quarter. Any delay in, or cancellation of, scheduled shipments and  customer
acceptances or in shipments from new orders could materially and adversely  affect our financial results.

Accounting rules addressing revenue  recognition  have added additional  complexity in  forecasting
quarterly revenue  and profitability. Orders  for  our  products usually contain multiple delivery elements
that result in revenue deferral under generally accepted accounting principles. Due to the foregoing
factors, investors should understand that  our actual financial results  for  a quarter may vary significantly

10

from our forecasts of financial performance for that quarter. Failure  to  meet forecasted financial
performance may have an adverse effect  on the price of our common stock.

The semiconductor industry is highly cyclical and  we expect that demand for  our  products will regularly
increase and decrease, making it difficult to manage the  business  and potentially causing harm  to our sales
and profitability.

The semiconductor business is highly  cyclical, experiencing upturns when the demand for our
products is high and downturns when our customers are  not  investing in new or  expanded  fabrication
facilities. From time to time, inventory  buildups in the  semiconductor industry,  resulting in part from
periodic downturns, produce an oversupply  of semiconductors. This will cause semiconductor
manufacturers to revise capital spending  plans, resulting in reduced demand for capital equipment such
as our products. If an oversupply is not  reduced by increasing demand from  the various electronics
industries that use semiconductors, which we  cannot accurately  predict, our  sales  and profitability  will
be harmed. Our revenue can vary significantly from  one  point in  the cycle  to  another,  making it
difficult to manage the business, both when revenue is increasing and when it  is decreasing. In addition,
a substantial portion of our operating expenses are fixed and do not fluctuate with changes in  volume.
Significant decreases in revenue can  therefore  have a disproportionate  effect  on profitability.

If we fail to compete successfully in the  highly competitive  semiconductor  equipment industry, our sales and
profitability will decline.

The market for semiconductor manufacturing equipment  is highly  competitive and includes
companies with substantially greater financial,  engineering, manufacturing, marketing and customer
service and support resources than we have that may be better positioned to compete successfully in
the industry. In addition, there are smaller,  emerging semiconductor equipment companies  that  provide
innovative systems with technology that may have  performance advantages over  our  systems. We expect
our  competitors to continue to improve  the design and performance of their existing  products and
processes and to introduce new products and processes with  improved price  and performance
characteristics. If we are unable to improve or introduce competing  products when demanded by the
markets, our business will be harmed.  In  addition,  if  competitors enter into strategic relationships with
leading semiconductor manufacturers  covering products similar to those sold or being developed by us,
our  ability to sell products to those manufacturers may be adversely  affected. Finally, if we must lower
prices to remain competitive without commensurate  cost of  goods savings, our  gross margins  and
profitability will be adversely affected.

We have  been dependent on sales to a limited  number of  large customers; the loss  of any  of  these customers or
any reduction in orders from them could  materially  affect our sales.

Historically, we have sold a significant portion  of our products and services to a  limited number  of

fabricators of semiconductor products. For  example, in 2011,  our top ten customers accounted for
68.6% of our net sales. None of our  customers has entered into a long-term agreement requiring it  to
purchase our products. Although the composition of the group comprising our largest customers has
varied from year to year, the loss of a significant  customer or  any  reduction or delays in orders from
any significant customer could adversely affect us. The ongoing consolidation of semiconductor
manufacturers may also increase the  harmful  effect of losing  one or more significant customers.

Axcelis is  subject to the risks of operating internationally and  we derive a substantial  portion of our  revenue
from  outside the United States, especially from Asia.

We  are substantially dependent on sales of our  products and services to customers outside the

United States. International sales, including  export sales from  our U.S. manufacturing facilities to
non-U.S.  customers and sales by our  non-U.S. subsidiaries and branches,  accounted for 72.3% of  total

11

revenue in 2011 in comparison to 75.8% in 2010  and  62.8% in 2009.  System shipments to Asian
customers represented 60% of total shipment  dollars in 2011 in comparison to 68% in 2010 and 76% in
2009. We anticipate that international sales will continue to account for  a significant  portion of our
revenue. Because of our dependence upon  international sales, our results and prospects may be
adversely affected by a number of factors, including:

(cid:129) unexpected changes in laws or regulations resulting in  more burdensome governmental controls,

tariffs,  restrictions, embargoes or export license  requirements;

(cid:129) difficulties in obtaining required export licenses;

(cid:129) volatility in currency exchange rates;

(cid:129) political and economic instability;

(cid:129) difficulties in accounts receivable collections;

(cid:129) extended payment terms beyond those  customarily offered in the  United States;

(cid:129) difficulties in managing suppliers, service  providers  or representatives outside the  United States;

(cid:129) difficulties in staffing and managing foreign  subsidiary and branch  operations; and

(cid:129) potentially adverse tax consequences.

We may  not be able to maintain and expand our business  if we  are  not  able to hire,  retain and  integrate
qualified personnel.

Our business depends on our ability to attract and retain qualified, experienced  employees. There

is substantial competition for experienced engineering, technical, financial, sales and marketing
personnel in our industry. In particular, we must  attract and retain  highly skilled design and  process
engineers. Competition for such personnel is  intense, particularly in the  Boston metropolitan area,  as
well as in other locations around the  world. If we  are unable to retain  our  existing key personnel, or
attract and retain additional qualified personnel, we may from  time to time experience levels  of  staffing
inadequate to develop, manufacture  and market our products and perform  services for  our customers.
As a result, our growth could be limited or  we could fail to meet our delivery  commitments or
experience deterioration in service levels or decreased customer satisfaction, all of  which could
adversely affect our financial results.

Our dependence upon a limited number  of  suppliers for  many components and sub-assemblies  could result in
increased costs or delays in the manufacture and  sale  of our  products.

We  rely to a substantial extent on outside  vendors  to  manufacture many of the  components and
sub-assemblies of our products. We obtain  many  of these  components  and  sub-assemblies from  either a
sole source or a limited group of suppliers. Accordingly, we may be unable  to  obtain  an adequate
supply of  required components on a  timely basis,  on price  and  other terms acceptable to us, or at all.

In addition, we often quote prices to  our  customers and accept customer orders for our products

before purchasing components and sub-assemblies  from our suppliers.  If our suppliers increase the cost
of components or sub-assemblies, we  may  not  have alternative sources of supply and  may not be able
to raise the price of our products to  cover  all  or part  of the increased cost  of  components.

The manufacture of some of these components and sub-assemblies is an extremely complex

process and requires long lead times.  As  a result, we have in the past, and may in  the future,
experience delays or shortages. If we  are  unable to obtain adequate  and timely  deliveries of our
required components or sub-assemblies, we may have  to  seek  alternative sources of supply or
manufacture these components internally. This could delay  our ability to manufacture  or to ship our

12

systems on a timely basis, causing us to  lose sales, incur additional costs, delay new  product
introductions and suffer harm to our reputation.

Our international operations involve currency risk.

Substantially all of our sales are billed  in U.S. dollars, thereby reducing the impact of  fluctuations
in foreign exchange rates on our results. Operating margins  of  certain foreign operations can  fluctuate
with changes in foreign exchange rates  to the extent  revenue is billed in U.S. dollars  and operating
expenses are incurred in the local functional currency. During the  year ended December  31, 2011,
approximately 21% of our revenue was derived from  foreign operations with  this inherent risk.  In
addition, at December 31, 2011, our operations  outside of the  United States accounted for
approximately 37% of our total assets,  the majority of which was denominated  in currencies other than
the U.S.  dollar.

Our stock price has been volatile and you could lose the value of your investment.

Our stock price has been volatile and has  fluctuated  significantly to date.  The trading price  of  our
stock is likely to continue to be highly volatile and subject  to  wide fluctuations. Your investment in  our
stock could lose value. Some of the factors that could significantly  affect  the market  price of our stock
include:

(cid:129) actual or anticipated variations in results;

(cid:129) analyst  reports or recommendations;

(cid:129) changes in interest rates; and

(cid:129) other events and factors, many of which  are beyond our control.

The stock market in general has experienced extreme  price  fluctuations.

Our proprietary technology may be vulnerable  to efforts by competitors to challenge or design  around,
potentially reducing our market share.

We  rely on a combination of patents, copyrights, trademark and trade  secret laws, non-disclosure
agreements and other intellectual property protection methods to protect our proprietary technology.
Despite our efforts to protect our intellectual  property, our competitors may be able to legitimately
ascertain the non-patented proprietary technology embedded in our  systems. If this occurs, we may  not
be able to prevent their use of this technology. Our  means of protecting  our  proprietary rights may not
be adequate and our patents may not  be  sufficiently broad to prevent others  from using technology that
is similar to or the same as our technology. In addition, patents issued to us have  been, or might  be
challenged, and might be invalidated or  circumvented  and any rights granted under  our patents  may
not provide adequate protection to us. Our competitors may  independently develop similar technology,
duplicate features  of our products or  design  around patents that may be issued  to  us. As a  result of
these threats to our proprietary technology, we  may have to resort to costly litigation to enforce or
defend  our intellectual property rights.  Finally, all patents expire after  a  period  of  time (in the  U.S.,
patents expire 20 years from the date  of  filing of the  patent  application). Our market share could be
negatively impacted by the expiration  of  a  patent  which had created a barrier for our competitors.

Axcelis also has agreements with third parties for licensing of patented or proprietary  technology
with Axcelis as the licensor or the licensee. Termination  of  license agreements could have an  adverse
impact on our financial performance or  ability to ship products  with existing configurations.

13

We (or customers that we indemnify) might face  intellectual  property infringement claims or patent disputes
that may be costly to resolve and, if resolved against us, could be very costly to  us and prevent  us from
making and selling our systems.

From time to time, claims and proceedings have been  or may  be  asserted  against us relative to
patent validity or infringement matters.  We typically agree  to  indemnify  our  customers from  liability to
third parties for intellectual property  infringement  arising  from the use  of  our products in  their
intended manner. Therefore, we occasionally  receive notification from  customers who  believe that we
owe them indemnification or other obligations related to infringement claims made  against the
customers by third parties. Our involvement in any patent dispute or other intellectual property dispute
or action to  protect trade secrets, even if the  claims  are without  merit, could be very expensive  to
defend  and could divert the attention  of our management. Adverse  determinations  in any  litigation
could subject us to significant liabilities to third parties,  require us  to  seek  costly  licenses from  third
parties and prevent us from manufacturing and selling  our systems. In addition, infringement
indemnification clauses in system sale agreements may require us to take other actions  or require us to
provide certain remedies to customers  who are exposed to indemnified liabilities.  Any  of  these
situations could have a material adverse effect on our  business results.

If operations were disrupted at Axcelis’ primary manufacturing facility  it would  have  a negative impact on our
business.

We  have one primary manufacturing  facility, located in Massachusetts. Its operations could be

subject to disruption for a variety of reasons, including, but not limited to natural  disasters, work
stoppages, operational facility constraints  and  terrorism.  Such disruption could cause delays in
shipments of products to our customers  and could result in cancellation of orders or  loss of  customers,
which  could seriously harm our business.

Overview

The semiconductor capital equipment industry is subject to significant  cyclical swings  in capital

spending by semiconductor manufacturers.  Capital spending is influenced  by  demand for
semiconductors and the products using them, the utilization rate and capacity of existing  semiconductor
manufacturing facilities and changes  in semiconductor  technology, all of  which are outside of our
control. As a result, our revenue and gross margins fluctuate from  year to  year and period to period.
We  typically become more efficient in  manufacturing  products as  they  mature. Our expense base is
largely fixed and does not vary significantly with changes  in volume. Therefore, we  experience
fluctuations in operating results and cash flows depending on  our revenue as  driven by the level of
capital expenditures by semiconductor manufacturers.

The sizable expense of building, upgrading or expanding a semiconductor fabrication facility  is

increasingly causing semiconductor companies to contract with foundries to  manufacture their
semiconductors. In addition, consolidation  and partnering within the semiconductor manufacturing
industry is increasing. We expect these  trends to continue  to  reduce the number of our potential
customers. This growing concentration of Axcelis’  customers may increase pricing pressure as higher
percentages of our total revenue are tied  to  the buying decisions of  a particular customer or a small
number of customers. Axcelis’ net revenue from its ten largest customers accounted for 68.6% of total
revenue for the year ended December  31, 2011 compared  to,  62.7%, and 56.6% of revenue for  the
years ended December 31, 2010 and 2009,  respectively.

After historic lows in 2009, the market for  our  products steadily improved during 2010  and we

gained market share with our single wafer  ion implant systems for high current and  high energy
applications (the Optima HDx and Optima  XEx). This market  recovery continued during the  first  half
of 2011, but during the second half of 2011,  deterioration within  the industry environment decreased
our  revenues as compared with the first half of the year. In addition, we had  delays in key penetrations
in the second half of 2011. These delays were a function of poor market conditions and issues in our
prioritization of new technology. However, in  2011 we continued to penetrate new customers  with our
Optima implant products which we expect will lead to additional future  sales.  In  2011 we  also gained
market share with our Integra dry strip  products. We  expect  the  industry  to  recover in 2012, and as  a
result, we believe that our financial results will  improve. In the event  that  industry conditions cause the
demand for Axcelis’ products to decline in future periods,  we  believe that we  can align manufacturing
and operating expense levels to changing  business conditions and  provide sufficient liquidity  to  support
operations.

Operating results for the years presented are not necessarily indicative of the results  that  may be

expected for future interim periods or years as  a whole.

Critical Accounting Estimates

Management’s discussion and analysis  of our financial condition and results  of  operations  are
based upon Axcelis’ consolidated financial statements, which have been  prepared  in accordance with
accounting principles generally accepted  in  the United States. The  preparation of these financial
statements requires management to make  estimates and judgments that  affect the  reported amounts of
assets, liabilities, revenue and expenses,  and related  disclosure of contingent assets and  liabilities. On an
on-going basis, we evaluate our estimates  and  assumptions. Management’s estimates are  based on
historical experience and on various  other  assumptions that are believed  to be reasonable under  the
circumstances, the results of which form the basis  for making judgments  about  the carrying values of
assets and liabilities that are not readily  apparent from  other sources. Actual results may differ from
these estimates under different assumptions  or conditions.

We  believe the following accounting policies are critical in the portrayal of our financial condition

and results of operations and require management’s  most significant judgments and  estimates in  the
preparation of our consolidated financial statements. For additional accounting policies see  Notes to
Consolidated Financial Statements Note  2. Significant  Accounting Policies.

Revenue Recognition

Our revenue recognition policy involves significant  judgment by  management. As  described below,

we consider a broad array of facts and circumstances in determining when  to  recognize revenue,
including contractual future service obligations to the customer, the complexity of the  customer’s post
delivery acceptance provisions, payment history, customer creditworthiness and  the installation process.
In the future, if the post delivery acceptance provisions and  installation  process become more complex
or result in a materially lower rate of  acceptance, we may have to revise our revenue  recognition policy,
which  could delay the timing of revenue recognition.

Axcelis’ system sales transactions are made up of multiple elements, including the  system itself and

elements that are not delivered simultaneously with the system. These undelivered  elements might
include a combination of installation services,  extended warranty  and support and spare parts, all of
which  are generally covered by a single sales price. Effective  January 1, 2011, we adopted Accounting
Standards Update, or ASU, No. 2009-13, Multiple Deliverable Revenue Arrangements, as required, using
the prospective method. Accordingly, this guidance is being applied to all system revenue arrangements
entered into or materially modified on  or after January  1, 2011. The  adoption of the amended guidance
did not change the accounting for arrangements entered  into  prior to January 1, 2011. There was  no
material impact on our financial position, results of operations or cash flows upon adoption and  we  do
not expect adoption will have a material  impact on our  future reporting periods  based on our  current
practices.

The impact of adopting this amended guidance  on our results of operations has been limited to

transactions involving the sale of systems.  ASU  No.  2009-13 amended the  previous guidance for
multiple-element arrangements. Pursuant to the amended guidance in ASU 2009-13, our system
revenue arrangements with multiple elements  are divided  into separate units of accounting  if specified
criteria are met, including whether the  delivered element has stand-alone value to the customer. If the
criteria are met, then the consideration  received is allocated among the separate units  based on  their
relative selling price, and the revenue  is recognized separately for  each  of  the separate  units.

We  determine selling price for each unit of accounting (element)  using vendor  specific objective

evidence (VSOE) or third-party evidence  (TPE), if they exist, otherwise, we  use best estimated selling
price (BESP). The Company generally  expects that it will not be able  to  establish TPE  due  to  the
nature of its products, and, as such, the Company typically  will determine selling price using VSOE  or
BESP.

19

Where required, the Company determines BESP  for an individual element based on consideration

of both market and Company-specific  factors, including  the selling  price and  profit margin  for similar
products, the cost to produce the deliverable  and the  anticipated  margin on that deliverable  and the
characteristics of the varying markets in which the  deliverable is sold.

The total consideration to be received in  the transaction is allocated  to  each element in the

arrangement based upon the relative  selling price of  each  element when compared  to  the consideration
received.

Systems are not sold separately and VSOE or TPE is not available for the  systems element.

Therefore the selling price associated  with systems is based on BESP. The allocated  value for
installation in the arrangement includes (a) the greater of (i) the relative  selling price of the  installation
or (ii) the portion or the sales price that will not be received until  the installation is completed (the
‘‘retention’’). The selling price of installation is  based upon  the fair value of the  service  performed,
including labor, which is based upon  the  estimated time  to complete  the installation at hourly rates,
and material components, both of which  are sold separately. The selling price  of  all  other elements
(extended warranty for support, spare parts,  and  labor) is based upon the price  charged when  these
elements are sold separately, or VSOE.

Product revenue for products which have demonstrated market acceptance,  is generally recognized

upon shipment provided title and risk of loss has  passed  to the customer,  evidence of an arrangement
exists, prices are contractually fixed or determinable, collection is  reasonably  assured through  historical
collection results and regular credit evaluations, and there  are  no  uncertainties regarding customer
acceptance. Revenue from installation  services  is recognized  at  the time formal  acceptance  is received
from the customer or, for certain customers, when both the formal acceptance  and retention payment
have been received. Revenue for other elements  is recognized at the  time products are shipped or the
related services are performed.

We  generally recognize product revenue for  systems which  have demonstrated market acceptance

at the time of shipment because the  customer’s post-delivery  acceptance provisions  and installation
process have been established to be routine, commercially inconsequential and  perfunctory. While some
customers accept Axcelis’ standard specifications, the majority of Axcelis’ systems are designed and
tailored to meet the customer’s specifications, as outlined  in the contract between the  customer and
Axcelis. To ensure that the customer’s  specifications are satisfied, many customers request  that  new
systems be tested at Axcelis’ facilities prior to shipment,  normally with the customer present, under
conditions that substantially replicate the customer’s production environment  and the  customer’s
criteria are confirmed to have been met. We believe the  risk  of  failure to complete a  system installation
is remote. Should an installation not  be  completed successfully, the contractual provisions do not
provide for forfeiture, refund or other  purchase  price concession beyond  those prescribed by the
provisions of the Uniform Commercial Code  applicable  generally to such transactions.

For initial shipments of systems with new technologies or  in the small number  of  instances where

Axcelis is unsure of meeting the customer’s specifications or  obtaining customer  acceptance  upon
shipment of the system, Axcelis will defer the recognition of systems revenue  and related costs  until
written customer acceptance of the system is obtained. This deferral period is generally  within twelve
months of shipment.

Revenue related to maintenance and service contracts is  recognized ratably over  the duration of

the contracts, or based on parts usage,  where  appropriate.  Revenue related to service hours is
recognized when the services are performed.

Royalty revenue was primarily earned under the terms of our license agreement with SEN. Royalty

revenue was recorded at the time SEN notified Axcelis that royalties had been earned.

20

Impairment of Long-Lived Assets

We  record impairment losses on long-lived assets  when events and circumstances indicate that

these assets might  not be recoverable. Recoverability is  measured by a  comparison of  the assets’
carrying  amount to their expected future  undiscounted net cash  flows. If such  assets are considered to
be impaired, the impairment is measured based  on the amount by  which the carrying  value exceeds its
fair value.

Future actual performance could be  materially different from our current forecasts, which could
impact future estimates of undiscounted cash flows and may result  in the impairment of  the carrying
amount of the long-lived assets in the future.  This could be caused by  strategic decisions made in
response to economic and competitive  conditions,  the impact of the economic environment on our
customer base, or a material adverse  change in  our relationships with significant  customers.

As of December 31, 2011 the Company completed a  test for recoverability due to indicators that
were present at December 31, 2011. Results of  this test indicated no impairment as  of December  31,
2011. The Company did not record an  impairment charge  for  the years ended December 31, 2011,
2010, or 2009.

Accounts  Receivable—Allowance for Doubtful Accounts

We  record an allowance for doubtful  accounts for estimated  losses resulting  from the inability of
our  customers to make required payments.  Our  allowance for doubtful  accounts is  established based on
a specific assessment of collectibility of our customer accounts.  If the financial condition of our
customers were to deteriorate, resulting in an impairment of their ability to make  payments, additional
allowances may be necessary.

Inventory—Allowance for Excess and Obsolescence

We  record an allowance for estimated excess and obsolete inventory.  The allowance  is determined

using management’s assumptions of materials  usage, based on estimates  of forecasted and  historical
demand and market conditions. If actual  market  conditions  become less favorable than those projected
by management, additional inventory write-downs may be required.

Although we make every effort to ensure the accuracy of our  forecasts or product  demand and

pricing assumptions, any significant unanticipated changes  in demand,  pricing, or  technical
developments would significantly impact the  value  of  our  inventory and our  reported operating results.
In the future, if we find that estimates  are  too optimistic  and determine that inventory needs to be
written down, the Company will recognize  such costs  in our  cost of revenue at the time of such
determination. Conversely, if we find our estimates are  too pessimistic and we subsequently  sell product
that has previously been written down, our gross margin in  that period will be favorably impacted.

Product Warranty

We  generally offer a one year warranty for  all  of  our  systems, the terms and  conditions of which

vary depending upon the product sold.  For all systems  sold, we accrue a  liability for the estimated cost
of standard warranty at the time of system shipment  and  defer  the portion of systems revenue
attributable to the fair value of non-standard warranty. Costs for  non-standard warranty are  expensed
as incurred. Factors that affect our warranty  liability  include the number of installed units, historical
and anticipated product failure rates, material usage  and  service  labor costs. We periodically assess  the
adequacy of our recorded liability and  adjust the amount as  necessary.

(6.4)% (58.4)%

Year ended December 31, 2011 in comparison to the year ended December 31, 2010

Revenue

Revenue increased significantly in 2011 compared to 2010 as  the  Company benefited  from
improving market conditions and increased capacity utilization at customers’ manufacturing facilities
during the first half of 2011. However during  the second half  of  2011, deterioration within the industry
environment resulted in a decrease in our revenues as  compared to the first half of the year.

Product

Product revenue, which includes systems  sales,  sales of  spare  parts and product upgrades, was
$237.9 million or 90.0% of revenue in 2011, compared  with $242.8  million,  or 88.2% of revenue in
2010. The increase in product revenue in 2011 is attributable to the strengthening of the semiconductor
market and a related increase in capital spending by semiconductor manufacturers during the first half

22

of 2011. However, our revenues decreased  during the second half of 2011  due  to  the weakening of  the
semiconductor market and the related delay  in capital spending by semiconductor manufacturers. In
addition, we had delays in key penetrations in the second half of  2011. These  delays were a function of
poor market conditions and issues in our  prioritization of new  technology. Despite this market
slowdown we believe we are gaining market traction with our single wafer  ion implant systems. During
2011, we also gained market share with  our  Integra dry strip products.

Approximately 24.9% of systems revenue in 2011 was from  sales of  200mm products and  75.1%

was from sales of 300mm products, compared  with 12.8%  and 87.2%  for sales of 200mm products  and
300mm products in 2010, respectively.

A portion of our revenue from system sales is deferred until installation  and other services  related
to future deliverables are performed. The total amount of deferred revenue at  December 31,  2011 and
2010 was $12.3 million and $16.3 million, respectively. The decrease  was  mainly due to the decrease in
systems sales in the second half of 2011  and the timing of acceptance of deferred  system sales.

Service

Service revenue, which includes the labor component of maintenance and service contracts  and
fees for service hours provided by on-site  service  personnel, was $32.1 million, or 10.0% of  revenue for
2011, compared with $32.4 million, or  11.8% of revenue, for  2010. Although  service  revenue should
increase with the expansion of the installed  base  of systems, it can  fluctuate from  period to period
based on capacity utilization at customers’ manufacturing facilities, which  affects the need for
equipment service. The slight decrease  during 2011  was primarily due  to  a decrease in  fabrication
utilization in the semiconductor industry  particularly during the  second half of  2011.

Revenue Categories used by Management

As an alternative to the line item revenue categories discussed above, management also uses

revenue categorizations which look at revenue  by product line (the most significant of which  is ion
implant) and by aftermarket, as described below.

Ion Implant

Included in total revenue of $319.4 million  in 2011 is  revenue  from  sales  of ion implantation

products and related service of $237.9 million, or  74.5% of total revenue, compared with $232.4 million,
or 84.4%, of total  revenue in 2010. The dollar increase was  due to the factors discussed  above for
product  revenue. Annual revenue from the sale of ion implantation products  and service typically
averages from 70% to 80% of total revenue.

Aftermarket

The Company’s product revenue includes sales  of spare parts and product upgrades as  well as
complete systems. We refer to the business  of selling  spare  parts and product upgrades, combined  with
the sale of maintenance labor and service contracts and service hours, as the  ‘‘aftermarket’’ business.
Included in total revenue of $319.4 million  in 2011 is  revenue  from  our aftermarket  business  of
$147.6 million, compared to $142.2 million  for 2010. Aftermarket revenue generally increases with
expansion of the installed base of systems but can fluctuate from period to period  based on  capacity
utilization at customers’ manufacturing  facilities which affects the sale of  spare parts and  demand for
equipment service.

23

Gross  Profit

Product

Gross profit from product revenue was  36.9% for the twelve months ended December 31, 2011,
compared to 30.8% for the twelve months ended December 31, 2010. The increase  in gross profit of
6.1 percentage points is due primarily  to  a favorable  mix of products at higher  margins and leveraging
our  on-going efforts to drive labor and material productivity through  lean, ship from  cell  and our global
sourcing efforts.

Service

Gross profit from service revenue was 27.0% for the  twelve  months ended December 31,  2011,
compared to 34.3% for the twelve months ended December 31, 2010. The decrease  in gross profit is
attributable to changes in the mix of service contracts and  the unfavorable absorption of fixed service
costs.

Research and Development

Research and development expense was  $47.2 million in 2011,  an increase of $7.7 million,  or
19.5%, compared with $39.5 million  in  2010. The increase was  primarily  payroll costs due to increased
headcount ($3.8 million), as well as increased amortization and depreciation costs for  assets used as
demonstration and/or test systems ($1.8  million),  increased  project material  costs ($1.1 million), and
increased professional fee expenses ($1.0  million).

Research and development expense was  attributable to the following activities for  2011: 57%  for
new product development, 30% for improvement and enhancement of existing products,  and 13%  for
product  testing.

Sales and Marketing

Sales and marketing expense was $29.3  million  in 2011, an  increase of $1.8  million,  or 6.5%,
compared with $27.5 million in 2010.  The increase was driven primarily by increased payroll  costs
($2.5 million), increased travel costs ($0.4 million),  increased freight costs ($0.1 million), increased
miscellaneous other ($0.4 million), offset  by decreased  supplies and  marketing costs ($1.6 million).

General and Administrative

General and administrative expense was  $31.2 million in 2011,  a decrease of $0.9 million,  or 2.8%
compared with $32.1 million in 2010.  The lower general and administrative  expense in  2011 was driven
primarily by decreased incentive compensation expense ($1.9  million), and decreased professional fee
expenses ($0.6 million), offset by increased payroll costs ($0.6  million),  increased separation costs
associated with the retirement of a former executive of  the Company ($0.3 million) and  increased other
miscellaneous costs ($0.7 million).

Other Income (Expense)

Other income (expense) for the year ended December  31, 2011 primarily consisted of foreign

exchange gains compared to foreign exchange  losses in 2010,  as a  result  of U.S. dollar currency
fluctuations against the local currencies of certain of  the countries in which we  operate.

For the year ended December 31, 2011  the Company incurred $1.2 million of foreign  exchange

gains. For the year ended December 31,  2010 the Company incurred $1.9 million  of foreign exchange
losses. Included in foreign exchange losses in 2010  are $0.3  million of foreign exchange  losses relating
to currency hedging activities.

24

Income Taxes

We  incur income tax expense relating principally to operating results of foreign entities  in

jurisdictions in Europe and Asia, where we earn  taxable income. We  have significant net  operating loss
carryforwards in the United States and certain European jurisdictions, and, as a result, we  do  not
currently pay significant income taxes in those jurisdictions. Additionally we do  not  recognize the tax
benefit for such losses in the United  States and certain European taxing jurisdictions. In the fourth
quarter of 2011, the Company recorded  a  tax expense of $0.9 million related to an uncertain tax
position in one of our European jurisdictions.

In 2010, the Company performed an evaluation of  the deferred tax assets  of certain of our foreign

subsidiaries for which the Company had  previously established a valuation allowance.  Based on  the
subsidiaries’ recent and expected ability to generate  taxable income,  the Company  reduced  the
subsidiaries’ corresponding valuation  allowance  and recognized a tax benefit  of $1.3 million.

Year ended December 31, 2010 in comparison to the year ended December 31, 2009

Revenue

Revenue increased significantly in 2010 compared to 2009 as  the  Company benefited  from
improving market conditions and increased capacity utilization at customers’ manufacturing facilities.
The Company expects this positive trend to continue into 2011.

Product

Product revenue, which includes systems  sales,  sales of  spare  parts and product upgrades, was
$242.8 million or 88.2% of revenue in 2010, compared  with $98.7  million,  or 74.2% of revenue in 2009.
The increase in product revenue in 2010 is attributable  to  the strengthening  of the semiconductor
market and a related increase in capital spending by semiconductor manufacturers. In addition, we also
believe we are gaining market share  with  our single wafer ion implant systems for  high current  and
high energy applications (the Optima  HDx and Optima  XEx), as customers are  showing a higher
acceptance of our technology.

Approximately 12.8% of systems revenue in 2010 was from  sales of  200mm products and  87.2%

was from sales of 300mm products, compared  with 25.0%  and 75.0%  for sales of 200mm products  and
300mm products in 2009, respectively.

A portion of our revenue from system sales is deferred until installation  and other services  related
to future deliverables are performed. The total amount of deferred revenue at  December 31,  2010 and
2009 was $16.3 million and $5.7 million, respectively. The increase was mainly due to the increase  in
systems sales in 2010.

Service

Service revenue, which includes the labor component of maintenance and service contracts  and
fees for service hours provided by on-site  service  personnel, was $32.4 million, or 11.8% of  revenue for
2010, compared with $33.9 million, or  25.5% of revenue, for  2009. Although  service  revenue should
increase with the expansion of the installed  base  of systems, it can  fluctuate from  period to period
based on capacity utilization at customers’ manufacturing facilities, which  affects the need for
equipment service. The slight decrease  during 2010  was primarily due  to  a decrease in  fabrication
utilization in the North American semiconductor industry.

25

Royalties

Royalties were previously earned under our prior license agreement with SEN. As  a result of  the

sale of our investment in SEN, SEN has  had no further  royalty obligations since March 30, 2009.
Royalty revenue was $0.4 million or  0.3% of revenue for  2009.

Revenue Categories used by Management

As an alternative to the line item revenue categories discussed above, management also uses

revenue categorizations which look at revenue  by product line (the most significant of which  is ion
implant) and by aftermarket, as described below.

Ion Implant

Included in total revenue of $275.2 million  in 2010 is  revenue  from  sales  of ion implantation

products and service of $232.4 million,  or 84.4% of total  revenue, compared with $110.9  million,  or
83.4%, of total revenue in 2009. The  dollar  increase was due to the factors discussed above for  product
revenue. Annual revenue from the sale of  ion implantation products and service typically averages from
70% to 80% of total revenue.

Aftermarket

The Company’s product revenue includes sales  of spare parts and product upgrades as  well as
complete systems. We refer to the business  of selling  spare  parts and product upgrades, combined  with
the sale of maintenance labor and service contracts and service hours, as the  ‘‘aftermarket’’ business.
Included in total revenue of $275.2 million  in 2010 is  revenue  from  our aftermarket  business  of
$142.2 million, compared to $98.2 million  for 2009. Aftermarket revenue generally increases with
expansion of the installed base of systems but can fluctuate from period to period  based on  capacity
utilization at customers’ manufacturing  facilities which affects the sale of  spare parts and  demand for
equipment service.

Gross  Profit

Product

Gross profit from product revenue was  30.8% for the twelve months ended December 31, 2010,

compared to 14.7% for the twelve months ended December 31, 2009. Approximately 3.3% of  the
16.1% increase resulted from a lower provision  for excess inventory.  The remaining  12.8% increase in
gross  profit from product revenue is  attributable to higher systems sales volume  and the  related
favorable absorption of fixed overhead costs which increased gross margins by 22.3%,  offset by a  9.5%
decrease in gross margin resulting from  an  unfavorable mix of parts and upgrade  revenue.

Service

Gross profit from service revenue was 34.3% for the  twelve  months ended December 31,  2010,
compared to 38.8% for the twelve months ended December 31, 2009. The decrease  in gross profit is
attributable to lower volumes.

Research and Development

Research and development expense was  $39.5 million in 2010,  an increase of $6.8 million,  or
20.8%, compared with $32.7 million  in  2009. The increase was  primarily  payroll costs due to increased
headcount ($3.1 million), increased professional fee expenses  ($2.4 million), increased project material
costs ($1.3 million), and increased asset  amortization and  depreciation  costs for assets  used  as
demonstration and/or test systems ($0.1  million).

26

Research and development expense was  attributable to the following activities for  2010: 53%  for

new product development, 31% for improvement of existing  products, and 16%  for product testing.

Sales and Marketing

Sales and marketing expense was $27.5  million  in 2010, an  increase of $2.3  million,  or 9.1%,
compared with $25.2 million in 2009  as  the Company  benefited from improved market conditions in
2010. The increase was driven primarily  by increased travel  costs  ($0.8 million), increased freight  costs
($0.8 million), increased supplies and  marketing costs ($0.4  million),  and  increased payroll costs
($0.3 million).

General and Administrative

General and administrative expense was  $32.1 million in 2010,  a decrease of $2.0 million,  or 5.9%
compared with $34.1 million in 2009.  The decrease was driven primarily by decreased  professional  fee
expenses ($4.6 million) primarily due  to  legal transaction  costs and  business outsourcing activities being
incurred in 2009 and a decrease in other miscellaneous costs ($0.4  million), offset  by  increased  payroll
and incentive compensation costs ($3.0 million).

Other Income (Expense)

Equity loss attributable to SEN was $3.2 million  for  the year ended December 31, 2009.  As a
result of the sale of the Company’s investment  in SEN, subsequent to March  30, 2009, the  Company no
longer records equity income or loss from SEN.

Interest income of $0.1 million for the  year  ended December 31, 2010, primarily relates  to  interest

earned on cash and cash equivalents. Interest income decreased by  $0.1 million from the  year ended
December 31, 2009, primarily due to lower average cash  balances  and lower interest rates.

We  had no interest expense for the year ended December 31, 2010. Our interest  expense was
$1.7 million for the year ended December 31, 2009.  We have had no  borrowings since we paid in full
our  convertible senior subordinated notes  on March  30, 2009.

For the year ended December 31, 2010  and  2009 the Company incurred  $1.9 million  of foreign
exchange losses. Included in foreign exchange  losses  in 2010  are $.3 million of foreign  exchange losses
relating to currency hedging activities. The  primary  reason for foreign  exchange losses in both years was
due to the weakening of the U.S dollar.

Income Taxes

We  incur income tax expense relating principally to operating results of foreign entities  in

jurisdictions, principally in Asia, where we earn taxable  income. We have  significant net operating loss
carryforwards in the United States and certain foreign jurisdictions, principally Europe, and,  as a result,
we do not currently pay significant income taxes  in those  jurisdictions and we do  not  recognize the tax
benefit for such losses as discussed in  Note 18  to  the consolidated  financial statements. Accordingly,
our  effective income tax rate is not meaningful.

27

In 2010, the Company performed an evaluation of  the deferred tax assets  of certain of our foreign

subsidiaries for which the Company had  previously established a valuation allowance.  Based on  the
subsidiaries recent and expected ability to generate  taxable income,  the Company  reduced  the
subsidiary’s corresponding valuation  allowance  and recognized a tax benefit  of $1.3 million.

Liquidity and Capital Resources

Capital expenditures were $2.1 million  and  $1.4 million  for  the years ended December 31, 2011

and 2010, respectively. We have no significant capital projects planned for 2012 and total capital
expenditures for 2012 are projected to be less  than  $2.5 million. Future capital expenditures beyond
2012 will depend on a number of factors, including the timing and rate of expansion of our business
and our ability to generate cash to fund  them.

We  have outstanding standby letters of credit, statutory liability  deposits  and surety bonds  in the
amount of $5.8 million to support certain  operating programs, workers’ compensation insurance, and
certain value added tax claims in Europe, of which $104,000 at  December  31, 2011 was  supported by
cash pledged as collateral. The pledged cash  is reflected as  long-term restricted cash on  the
consolidated balance sheet.

Payments Due by Period

We  have no off-balance sheet arrangements  at December 31,  2011.

Our liquidity is affected by many factors. Some of  these relate specifically to the  operations  of  our

business, for example, the rate of sale of our  Optima and Integra  products, and others relate to the
uncertainties of global economies, including  the availability  of  credit, and the condition  of  the overall
semiconductor equipment industry.

We  have net operating loss and tax credit carryforwards the  tax  effect of which aggregate

$108.2 million at December 31, 2011.  These  carryforwards,  which expire principally between  2021 and
2031, are available to reduce future income tax liabilities  in the United States and  certain  foreign
jurisdictions.

In 2011, $3.5 million of cash was generated  by operating activities compared to a cash use of

$5.9 million in 2010. The $9.4 million  increase  in cash  generated by operations in 2011  was
predominately driven by the Company’s  income from operations  in addition  to  noncash  charges  for
depreciation and amortization and stock  based compensation expense. Cash  and cash equivalents at
December 31, 2011 were $46.9 million,  compared to $45.7 million at December 31,  2010. Working

28

capital at December 31, 2011 was $164.6  million. Approximately $15.6 million  of cash  is located in
foreign jurisdictions as of December  31,  2011.

It  is Company policy to provide taxes for the total anticipated  tax impact  of the undistributed
earnings of our wholly-owned foreign  subsidiaries’ as such earnings  are  not expected  to  be  reinvested
indefinitely. The Company anticipates that  US tax resulting from remitting such earnings will be off-set
by net operating loss or credit carryforwards to the extent  available. In  addition,  the Company does not
anticipate incurring a foreign withholding  tax on remitting such earnings since it does not intend  to
remit the earnings as dividends.

On April 25, 2011, the Company amended  its  existing revolving credit  facility  with a bank. The
amended agreement provides for borrowings up to $30 million  based primarily on  accounts receivable.
The facility has certain financial covenants requiring us to maintain minimum  levels of operating results
and liquidity. The  agreement will terminate on  April 10,  2015. The Company uses the facility to
support letters of credit and hedging  transactions.

On December 27, 2011, the Company entered  into  a modification agreement relating to this
facility, which revises the Company’s  covenant to require  a minimum trailing six month  adjusted net
income (as defined in the agreement)  for the six month period ending  December 31,  2011 of
($3,000,000).

At December 31, 2011 the Company’s available borrowing capacity  under the  amended credit

facility was $23.3 million and the Company was  compliant  with all  covenants of the loan  agreement.

We  believe that based on our current market, revenue and expense forecasts,  our existing cash  and

cash equivalents will be sufficient to  satisfy our anticipated cash requirements  in the short and
long-term. Our 2012 forecast reflects revenue and gross margins  consistent with our  understanding of
customer plans, the market conditions  currently  forecasted  by the industry, and  capacity utilization at
customers’ manufacturing facilities.

Related-Party Transactions

There are no significant related-party transactions  that require disclosure in  the consolidated
financial statements for the year ended December 31, 2011,  or in this Annual Report on Form 10-K.

Recent  Accounting Pronouncements

A discussion of recent accounting pronouncements is included in Note 2 to the  consolidated

financial statements for the year ended December 31, 2011  included in  this  Annual Report  on
Form 10-K.

Item 7A. Quantitative and Qualitative Disclosures about Market  Risk.

Interest Rate Sensitivity

Axcelis’ exposure to market risk for changes  in interest rates relates primarily to our investment
portfolio, which consists entirely of cash-equivalents at December 31, 2011. The primary objective of
our  investment activities is to preserve  principal while maximizing yields without  significantly  increasing
risk. This is accomplished by investing  in  marketable  high investment grade securities and  limiting
exposure to any one issue or issuer. We  do not use derivative financial instruments  in managing  our
investment portfolio and, due to the nature  of  our  investments, we  do not expect  our operating results
or cash flows to be affected to any significant degree by any change in market interest rates.

29

Foreign Currency Exchange Risk

Substantially all of our sales are billed  in U.S. dollars, thereby reducing the impact of  fluctuations
in foreign exchange rates on our results. Operating margins  of  certain foreign operations can  fluctuate
with changes in foreign exchange rates  to the extent  revenues  are  billed in U.S. dollars  and operating
expenses are incurred in the local functional currency. During the  years  ended December  31, 2011 and
2010, approximately 21% and 24% of our revenue were derived  from  foreign operations with  this
inherent risk. In addition, at both December 31,  2011 and 2010, our operations outside of the United
States accounted for approximately 37%  and  34% of our total  assets, respectively, the  majority of which
was denominated in currencies other  than the U.S.  dollar.

Evaluation of Disclosure Controls and  Procedures.

Our management, with the participation of our principal executive officer and principal financial

officer, has evaluated the effectiveness  of  our disclosure controls and procedures (as defined in
Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended  (the  ‘‘Exchange Act’’))  as of
the end of the period covered by this  annual  report (the ‘‘Evaluation Date’’). Based on this evaluation,
our  principal executive officer and principal financial officer concluded  that,  as of the Evaluation Date,
these disclosure controls and procedures  are effective.

Internal Control over Financial Reporting

Management’s Annual Report on Internal  Control over Financial Reporting

Management is responsible for establishing and maintaining adequate internal  control  over
financial reporting, as such term is defined in Rule 13a-15(f)  under  the Exchange Act.  Because of its
inherent limitations, internal control over financial reporting  may  not prevent or  detect  all
misstatements. A control system, no  matter  how well  designed  and operated, can provide only
reasonable assurance with respect to financial  statement preparation and  presentation. 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.

Management assessed the effectiveness of our internal control over financial  reporting as of

December 31, 2011. In making this assessment, management used the  criteria set forth in the
Committee of Sponsoring Organizations  of  the Treadway Commission (COSO) Internal Control-
Integrated Framework.

Based on this assessment, management has concluded that, as of  December 31, 2011, our internal

control over financial reporting is effective based on those criteria.

The independent registered public accounting  firm  of Ernst & Young  LLP, as auditors of our
consolidated financial statements, has  issued an attestation report  on its  assessment  of  our  internal
control over financial reporting.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders of  Axcelis Technologies, Inc.

We  have audited Axcelis Technologies, Inc.’s internal control over  financial reporting as  of

December 31, 2011, based on criteria established in Internal Control—Integrated Framework issued  by
the Committee of Sponsoring Organizations  of the Treadway Commission  (the  COSO criteria). Axcelis
Technologies, Inc.’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. Our responsibility is to express an  opinion on  the Company’s internal control over financial
reporting based on our audit.

We  conducted our audit in accordance with the standards of  the Public Company Accounting
Oversight Board (United States). 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.

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.

In our opinion, Axcelis Technologies, Inc. maintained, in  all material  respects, effective internal

control over financial reporting as of  December 31, 2011,  based on the COSO criteria.

We  also have audited, in accordance with the standards of  the Public Company Accounting
Oversight Board (United States), the  consolidated balance sheets of Axcelis  Technologies, Inc.  as of
December 31, 2011 and 2010, and the related consolidated statements of operations, stockholders’
equity, and cash flows for each of the three years in the period ended December 31, 2011  of  Axcelis
Technologies, Inc. and our report dated February 29, 2012 expressed an unqualified  opinion thereon.

Changes  in Internal Control over Financial Reporting

There was no change in our internal control over  financial  reporting (as defined in Rule 13a-15(f)

under the Exchange Act) identified in connection with  the evaluation of our internal control that
occurred during our fourth quarter that has  materially affected, or is  reasonably  likely to materially
affect, our internal control over financial  reporting.

Item 9B. Other Information.

The Company entered into Amended  and Restated Indemnification Agreements  dated

February 28, 2012 with each of its current directors  and  officers  to  conform to an updated form  of
Indemnification Agreement. The previous  form of Indemnification Agreement was  adopted in June,
2000 and the Board determined that certain provisions required clarification or  enhancement  in light of
court decisions interpreting indemnification agreements during the  period since the previous  form was
adopted. These amendments:

(cid:129) add language providing for a neutral decision-maker in  the event of a change in control and

certain presumptions benefiting the director  or officer;

(cid:129) clarify and elaborate on a number  of definitions  and other terms;

(cid:129) eliminate the Company’s obligation to maintain an escrow account  for the  benefit of the

indemnitees.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders of  Axcelis Technologies, Inc.

We  have audited the accompanying consolidated balance sheets of Axcelis  Technologies, Inc. (the

‘‘Company’’) as of December 31, 2011 and 2010, and  the related consolidated  statements of operations,
stockholders’ equity, and cash flows for  each of the three years  in the period ended December 31,
2011. Our audits also included the financial statement schedule  listed in the index  at Item  15(a). These
financial statements and schedule are  the responsibility of the Company’s management. Our
responsibility is to express an opinion  on  these  financial statements and  schedule based  on our audits.

We  conducted our audits in accordance with the standards  of  the Public Company Accounting
Oversight Board (United States). Those  standards require that we  plan and perform the audit to obtain
reasonable assurance about whether  the  financial  statements are free  of material misstatement.  An
audit includes examining, on a test basis, evidence  supporting the amounts and disclosures  in the
financial statements. An audit also includes assessing the accounting  principles used  and significant
estimates made by management, as well as  evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable  basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects,
the consolidated financial position of  Axcelis Technologies, Inc. at December 31, 2011  and 2010,  and

Axcelis Technologies, Inc.
Notes to Consolidated Financial Statements

Note 1. Nature of Business

Axcelis Technologies, Inc. (‘‘Axcelis’’  or the ‘‘Company’’), is a worldwide producer  of  ion

implantation, dry strip and other processing equipment  used  in the fabrication of semiconductor chips
in the United States, Europe and Asia.  In addition, the Company provides extensive aftermarket
service and support, including spare parts, equipment  upgrades, and  maintenance services to the
semiconductor industry.

Until March 30, 2009, the Company  owned 50%  of the equity of a joint venture with Sumitomo

Heavy Industries, Ltd. (‘‘SHI’’) in Japan. This joint  venture, which was known as SEN, licensed
technology from the Company relating to the manufacture of specified ion  implantation  products and
had exclusive rights to manufacture and sell these products in  the territory of Japan. On March 30,
2009, the Company sold to SHI all of  the Company’s common shares in  SEN,  in exchange  for a  cash
payment of 13 billion Yen, which resulted in  proceeds of approximately $132.8  million before advisor
fees and other expenses of $10.6 million.  The sales price was determined through an arm’s  length
negotiation. This transaction terminated all  prior agreements among  the three parties  relating to the
SEN joint venture. In addition, the arbitration with  SEN  initiated  by Axcelis in  Tokyo was dismissed.
Detailed  information about the Company’s investment  in SEN is  provided in Note 17. A portion of the
proceeds of the sale were used to pay off, in full, the amounts due to the  holder of the Company’s
4.25% Convertible Senior Subordinated  Notes.

Note 2. Significant Accounting Policies

Principles of Consolidation

The consolidated financial statements include the accounts  of Axcelis and its wholly-owned,

controlled subsidiaries. All intercompany balances and transactions have  been eliminated  in
consolidation.

Use of Estimates

The preparation of consolidated financial statements in conformity with generally  accepted

accounting principles requires management  to  make estimates and assumptions that affect the  amounts
reported in the consolidated financial statements and accompanying notes.  Actual results could differ
from those estimates.

Foreign Currency

The functional currency for substantially all operations outside  the United States is the  local
currency. Financial statements for these  operations are  translated into United States dollars at year-end
rates as to assets and liabilities and average  exchange rates  during  the year  as to revenue  and expenses.
The resulting translation adjustments are  recorded in  stockholders’ equity as an element of
accumulated other comprehensive income  (loss).  Foreign  currency transaction gains  and losses  are
included in other income (expense) in the  consolidated statements of  operations.

For the year ended December 31, 2011  the Company incurred $1.2 million of foreign  exchange

gains. For the year ended December 31,  2010 the Company incurred $1.9 million  of foreign exchange
losses.

F-6

Cash and Cash Equivalents

Cash and cash equivalents consist of  cash on hand  and  highly liquid investments with original
maturities of ninety days or less. Cash equivalents consist primarily  of  money market securities and
certificates of deposit. Cash equivalents  are  carried  on the balance  sheet at fair market value.

Inventories

Inventories are carried at lower of cost,  determined using the first-in, first-out (FIFO)  method, or

market. The Company periodically reviews its inventories and  makes  provisions  as necessary for
estimated obsolescence or damaged goods  to  ensure values  approximate  lower of cost or market. The
amount of such markdowns is equal  to  the difference  between cost of inventory  and the  estimated
market value based upon assumptions  about future  demands, selling  prices, and market conditions.

Axcelis records an allowance for estimated  excess  inventory. The allowance is determined using
management’s assumptions of materials usage, based on estimates  of demand and  market  conditions. If
actual market conditions become less  favorable  than those projected by  management, additional
inventory write-downs may be required.

Property, Plant and Equipment

Property, plant and equipment are recorded at cost. Depreciation is computed using  the

straight-line method. The historical cost of buildings is depreciated  over forty years and machinery and
equipment principally over three to ten  years.  Expenditures for maintenance and repairs  are expensed
as incurred. Expenditures for renewals  and betterments are capitalized.

Impairment of Long-Lived Assets

The Company records impairment losses on  long-lived assets  when events and  circumstances
indicate that these assets might not be recoverable.  Recoverability is measured by a comparison of the
assets’ carrying amount to their expected  future undiscounted net cash flows. If such assets are
considered to be impaired, the impairment  is measured  based on the amount by which  the carrying
value exceeds its fair value. As of December 31,  2011 the Company completed a  test for recoverability
due to indicators that were present at  December  31, 2011. Results  of this  test indicated no  impairment
as of  December 31, 2011. The Company did not  record an impairment  charge for the years ended
December 31, 2011, 2010, or 2009.

Future actual performance could be  materially different from our current forecasts, which could
impact future estimates of undiscounted cash flows and may result  in the impairment of  the carrying
amount of the long-lived assets in the future.  This could be caused by  strategic decisions made in
response to economic and competitive  conditions,  the impact of the economic environment on our
customer base, or a material adverse  change in  the Company’s relationships with  significant customers.
The Company performs an impairment analysis  when circumstances or events warrant.

Concentration of Risk

Financial instruments, which potentially expose Axcelis  to  concentrations  of credit risk,  consist
principally of accounts receivable and  cash  equivalents. Axcelis’ customers  consist of semiconductor
manufacturers located throughout the world. Axcelis’  net sales to its  ten largest  customers accounted
for 68.6%, 62.7%, and 56.6% of revenue  in  2011, 2010, and 2009, respectively.

Axcelis performs ongoing credit evaluations of its customers’ financial condition and generally

requires no collateral to secure accounts receivable.  For selected overseas sales, Axcelis  requires
customers to obtain letters of credit before product is shipped. Axcelis maintains an allowance for
doubtful accounts based on its assessment  of the collectability of accounts  receivable. The Company

F-7

reviews the allowance for doubtful accounts monthly. The  Company does  not  have any  off-balance-
sheet credit exposure related to its customers.

Axcelis’ exposure to market risk for changes  in interest rates relates primarily to cash equivalents.
The primary objective of the Company’s  investment activities is to preserve principal while maximizing
yields without significantly increasing  risk. This  is accomplished by investing in marketable  high
investment grade securities and limiting exposure to any one issue or issuer. The Company  does not
use derivative financial instruments to manage its investment portfolio and does  not  expect operating
results or cash flows to be affected to any significant degree by any change in  market  interest rates.

Some of the components and sub-assemblies included in  the Company’s products are  obtained
either from a sole source or a limited group of suppliers. Disruption to the Company’s supply  source,
resulting either from depressed economic conditions or other  factors, could affect its ability to deliver
products to its customers.

Accumulated Other Comprehensive Income

Comprehensive income is comprised  of two  components,  net loss  and other  comprehensive income.
Other comprehensive income consists  of foreign currency translation adjustments and the effects of the
minimum pension liability. The following table shows  the cumulative components of accumulated other
comprehensive income for the years  ended December 31, 2011,  2010 and  2009:

Fair  Value of Financial Instruments

The carrying amounts of certain of the Company’s financial instruments, including  cash

equivalents, accounts receivable, accounts  payable and other accrued liabilities  approximate fair  value
due to their  short maturities.

Revenue Recognition

The Company’s revenue recognition policy  involves significant  judgment by management. As
described below, the Company considers  a broad  array  of facts and  circumstances  in determining when
to recognize revenue, including contractual  obligations to the customer, the complexity  of the
customer’s post delivery acceptance provisions, payment history, customer  creditworthiness and the
installation process. In the future, if the  post delivery  acceptance provisions  and installation process
become  more complex or result in a materially lower rate of acceptance,  the Company may  have to
revise its revenue recognition policy,  which could delay  the timing of  revenue recognition.

Axcelis’ system sales transactions are made up of multiple elements, including the  system itself and

elements that are not delivered simultaneously with the system. These undelivered  elements might
include a combination of installation services,  extended warranty  and support and spare parts, all of
which  are covered generally by a single sales price. Effective  January 1, 2011, the Company  adopted
Accounting Standards Update, or ASU, No. 2009-13, Multiple Deliverable Revenue Arrangements, as
required, using the prospective method.  Accordingly, this guidance is being applied to all system
revenue arrangements entered into or materially modified on  or after January 1, 2011.  The  adoption of
the amended guidance did not change the  accounting for arrangements  entered  into  prior to January 1,
2011. There was no material impact  on our  financial position,  results of operations or  cash flows upon

F-8

adoption and we do not expect adoption  will have  a material impact on  our future reporting periods
based on our current practices.

The impact of adopting this amended guidance  on the  Company’s results  of operations  has been

limited to transactions involving the sale  of systems.  ASU No. 2009-13 amended the previous  guidance
for multiple-element arrangements. Pursuant to the amended  guidance in ASU  2009-13, the Company’s
system revenue arrangements with multiple elements are divided into separate units of accounting  if
specified criteria are met, including whether the delivered element has stand-alone  value to the
customer. If the criteria are met, then the  consideration received  is allocated among the  separate units
based on their relative selling price, and  the  revenue is  recognized separately  for each  of  the separate
units.

The Company determines selling price for each unit  of accounting (element) using vendor specific

objective evidence (VSOE) or third-party evidence  (TPE), if they exist,  otherwise, the Company uses
best estimated selling price (BESP).  The  Company generally  expects that it  will not be able to establish
TPE due to the nature of its products, and, as  such, the Company  typically will determine selling  price
using VSOE or BESP.

Where required, the Company determines BESP  for an individual element based on consideration

of both market and Company-specific  factors, including  the selling  price and  profit margin  for similar
products, the cost to produce the deliverable  and the  anticipated  margin on that deliverable  and the
characteristics of the varying markets in which the  deliverable is sold.

The total consideration to be received in  the transaction is allocated  to  each element in the

arrangement based upon the relative  selling price of  each  element when compared  to  the consideration
received.

Systems are not sold separately and VSOE or TPE is not available for the  systems element.

Therefore the selling price associated  with systems is based on BESP. The allocated  value for
installation in the arrangement includes (a) the greater of (i) the relative  selling price of the  installation
or (ii) the portion or the sales price that will not be received until  the installation is completed (the
‘‘retention’’). The selling price of installation is  based upon  the fair value of the  service  performed,
including labor, which is based upon  the  estimated time  to complete  the installation at hourly rates,
and material components, both of which  are sold separately. The selling price  of  all  other elements
(extended warranty for support, spare parts,  and  labor) is based upon the price  charged when  these
elements are sold separately, or VSOE.

Product revenue for products which have demonstrated market acceptance,  generally recognized
upon shipment provided title and risk of loss has  passed  to the customer,  evidence of an arrangement
exists, prices are contractually fixed or determinable, collectability  is reasonably assured through
historical collection results and regular credit evaluations, and  there  are  no  uncertainties regarding
customer acceptance. Revenue from  installation services is recognized at the  time formal acceptance is
received from the customer or, for certain customers, when both the formal acceptance  and retention
payment have been received. Revenue for  other elements  is recognized at the  time products are
shipped or the related services are performed.

The Company generally recognizes revenue  for products which  have demonstrated market
acceptance at the time of shipment because  the customer’s  post-delivery acceptance provisions  and
installation process have been established to be routine, commercially inconsequential and  perfunctory.
The majority of Axcelis’ systems are designed and tailored to meet the customer’s  specifications, as
outlined in the contract between the customer  and  Axcelis, which  may be  the Axcelis standard
specification. To ensure that the customer’s specifications are satisfied, many customers request that
new systems be tested at Axcelis’ facilities  prior to shipment, normally with  the customer  present,  under
conditions that substantially replicate the customer’s production environment  and the  customer’s

F-9

criteria are confirmed to have been met. The Company believes  the  risk of  failure to complete a  system
installation is remote. Should an installation not be completed successfully, the  contractual  provisions
do not provide for forfeiture, refund or other purchase price concession  beyond those prescribed  by the
provisions of the Uniform Commercial Code  applicable  generally to such transactions.

For initial shipments of systems with new technologies or  in the small number  of  instances where

Axcelis is unsure of meeting the customer’s specifications or  obtaining customer  acceptance  upon
shipment of the system, Axcelis will defer the recognition of systems revenue  and related costs  until
written customer acceptance of the system is obtained. This deferral period is generally  within twelve
months of shipment.

Revenue related to maintenance and service contracts is  recognized ratably over  the duration of

the contracts, or based on parts usage,  where  appropriate.  Revenue related to service hours is
recognized when the services are performed.

Product revenue includes revenue from system sales, sales  of spare parts, the spare parts

component of maintenance and service contracts and product upgrades. Service revenue includes the
labor component of maintenance and service  contract amounts  charged for  on-site service personnel.

Shipping and Handling Costs

Shipping and handling costs are included  in cost of  revenue.

Stock-Based Compensation

The Company recognizes compensation expense for all share-based payments to employees and
directors, including grants of employee  stock options, based  on the grant-date fair value of those  share-
based payments using the Black- Sholes option pricing model, adjusted for expected forfeitures. Stock-
based compensation expense is recognized ratably  over the requisite service  period.

See Note 12 for additional information relating  to  stock-based compensation.

Income Taxes

The Company records income taxes using the asset and liability  method. Deferred income tax
assets and liabilities are recognized for  the future tax consequences attributable  to  differences between
the financial statement carrying amounts of existing assets  and liabilities and their respective  income tax
bases, and operating loss and tax credit  carryforwards. The Company’s  consolidated  financial statements
contain certain deferred tax assets which  have arisen  primarily  as a result of operating losses, as well  as
other temporary differences between  financial and tax accounting. The Company establishes a  valuation
allowance if the likelihood of realization  of the deferred tax  assets is reduced based on  an evaluation of
objective verifiable evidence. Significant  management  judgment is required  in determining the
Company’s provision for income taxes, the Company’s deferred tax assets and  liabilities  and any
valuation allowance recorded against  those net deferred tax  assets. The Company  evaluates the  weight
of all available evidence to determine whether it is more  likely than not that some portion or  all  of  the
net deferred income tax assets will not  be  realized.

Income taxes include the largest amount of tax benefit for an uncertain tax position that is more
likely than not to be sustained upon audit based  on the technical merits  of the tax position.  Settlements
with tax authorities, the expiration of  statutes of limitations for particular tax positions, or obtaining
new information on particular tax positions may cause a change  to  the effective tax  rate. The  Company
recognizes accrued interest related to unrecognized tax benefits  as interest expense  and penalties as
operating expense.

Net Income (Loss) per Share

Basic earnings per share is computed by  dividing  income  available to common stockholders (the

numerator) by the weighted-average  number of common shares  outstanding (the denominator) for the
period. The computation of diluted earnings  per  share is  similar  to  basic earnings per share, except  that
the denominator is increased to include the number of additional common shares  that  would have been
outstanding if the potentially dilutive  common  shares had been  issued, calculated using  the treasury
stock method.

Because the Company had a net loss  for each  of the years ended December 31,  2010 and  2009,
any common shares related to outstanding  stock  options,  restricted  stock, restricted stock  units and
convertible debt have been excluded from the  calculation  of  net loss per share because the effect would
have been anti-dilutive.

Recent  Accounting Pronouncements

In June 2011, the Financial Accounting  Standards Board, or FASB, issued Accounting Standards

Update, or ASU, No. 2011-05, Comprehensive Income (Topic 220). This newly issued accounting
standard (1) eliminates the option to present the components of other comprehensive income as  part of
the statement of changes in stockholders’ equity;  (2) requires  the consecutive presentation of the
statement of net income and other comprehensive income; and (3)  requires an  entity  to  present
reclassification adjustments on the face of the financial statements from other comprehensive income to
net income. This update does not change the  items that  must  be  reported  in other comprehensive
income or when an item of other comprehensive income must be reclassified to net income nor  does it
affect how earnings per share is calculated or presented. In December, 2011, The Financial Accounting
Standards Board (FASB) issued Accounting Standards Update No.  2011-12, Comprehensive Income
(Topic 220): Deferral of the Effective Date  for Amendments to the Presentation of Reclassifications of Items
Out of Accumulated Other Comprehensive Income in Accounting Standards Update No.  2011-05. The
Update defers the specific requirement to present items that are reclassified from accumulated other
comprehensive income to net income  separately with their  respective components of net income and
other comprehensive income. The Board  did  not defer the requirement to report comprehensive
income either in a single continuous statement or in  two separate but  consecutive  financial  statements.
This update is required to be applied  retrospectively and is effective for us  for fiscal  years  (and interim
periods within those years) beginning on  or after January 1, 2012. As  this update only requires
enhanced disclosure, the adoption of  this update will not impact our financial position or results of
operations.

When recorded, inventory reserves are intended to reduce the carrying  value  of  inventories to their

net realizable value. The Company establishes  inventory reserves when conditions  exist that indicate
inventory may be in excess of anticipated demand  or is  obsolete based upon assumptions about future
demand for the Company’s products or market conditions. The Company regularly evaluates the ability
to realize the value of inventories based  on a combination of factors including the following: forecasted
sales or usage, estimated product end  of life  dates, estimated  current and future  market value and new
product  introductions. Purchasing and  usage alternatives  are also explored  to  mitigate  inventory
exposure. As of December 31, 2011 and  2010, inventories are  stated net of inventory reserves of
$22.8 million and $27.5 million respectively.  The  decrease in inventory  reserves  in 2011 is primarily  due
to the sale or disposal of $5.6 million  of  previously reserved inventory.

Note 9. Product Warranty

The Company generally offers a one  year warranty for all of its systems,  the  terms and conditions

of which vary depending upon the product  sold.  For all  systems sold, the Company  accrues a  liability
for the estimated cost of standard warranty at the time  of system shipment and defers the  portion of
systems revenue attributable to the fair  value of non-standard warranty.  Costs for non-standard
warranty are expensed as incurred. Factors  that affect  the Company’s warranty liability include  the
number of installed units, historical and  anticipated product  failure rates, material usage  and service
labor costs. The Company periodically assesses  the adequacy of its recorded liability and  adjusts  the
amount as necessary.

Note 10. Financing Arrangements

Convertible Subordinated Debt

On March 30, 2009, Axcelis used $85 million of the proceeds of its sale of SEN to pay in  full its

outstanding 4.25% Convertible Senior Subordinated  Notes  which it  had issued  in May 2006.

Bank Credit Facility

On April 25, 2011, the Company amended  its  revolving credit facility. The amended agreement

provides for borrowings up to $30 million based primarily on accounts  receivable.  The facility  has
certain financial covenants requiring us  to maintain minimum levels  of operating results and  liquidity.
The agreement will terminate on April 10,  2015. The Company uses  the  facility  to  support letters  of
credit and hedging transactions.

On December 27, 2011, the Company entered  into  a modification agreement relating to this
facility, which revises the Company’s  covenant to require  a minimum trailing six month  adjusted net
income (as defined in the agreement)  for the six month period ending  December 31,  2011 of
($3,000,000).

At December 31, 2011 the Company’s available borrowing capacity  under the  amended credit

facility was $23.3 million and the Company was  compliant  with all  covenants of the loan  agreement.

Note 11. Defined Contribution Plan

The Company maintains the Axcelis  Long-Term Investment Plan, a defined contribution  plan. All

regular employees are eligible to participate  and  may  contribute  up to 35% of their compensation on a
before-tax basis subject to IRS limitations. Highly compensated employees may contribute up to 16%
of their compensation on a before-tax  basis subject to IRS limitations. The Company suspended
matching contributions in 2009, so no  expense was recorded for this plan in 2011, 2010  or 2009.

Note 12. Stock Award Plans and Stock-Based  Compensation

2000 Stock Plan

The Company maintains the Axcelis  Technologies, Inc. 2000  Stock Plan (the ‘‘2000  Plan’’), a stock

award and incentive plan which permits the  issuance  of  options, stock appreciation rights, restricted
stock, restricted stock units, and performance awards  to  selected  employees, directors and  consultants
of the Company. The 2000 Plan originally  reserved 18.5 million shares of common stock for future
grant, which amount was subsequently increased to 33.2  million shares of common  stock.  The 2000
Plan expires in 2012. At December 31, 2011, there  were 7.3 million shares  of  common stock available
for future grant. At December 31, 2011, stock awards outstanding  under the  2000 Plan included  stock
options, restricted stock and restricted  stock units.

Expiration of non-qualified stock options or  stock appreciation rights is based  on award

agreements. Non-qualified stock options typically  expire ten years from date of grant,  but, if approved
by the Board of Directors, may have a stated term  in excess of ten years. Incentive  stock  option awards
expire ten years from the date of grant. Generally,  options granted  to  employees terminate  upon
termination of employment. Under the  terms of the  2000 Plan, the exercise  price, determined by the
Board of Directors, may not be less than  the fair market value of a share of the Company’s common
stock on the date of grant. Stock options granted  to  employees generally  vest over a  period of  four
years, while stock options granted to  non-employee members of the Company’s Board  of  Directors
generally vest over a period of 6 months  and, once  vested,  are  not affected  by  the director’s
termination of service to the Company.  The Company settles  stock option exercises with newly issued
common shares.

F-15

Generally, unvested restricted stock and  restricted stock unit awards  expire upon termination of
service to the Company. Restricted stock  or restricted stock  unit awards granted to employees generally
vest over a period of four years, while  restricted stock  or restricted stock  units granted to members  of
the Company’s Board of Directors generally vest over a  period of six months.  The  Company plans to
settle restricted stock units upon vesting with newly issued common shares.

Under the 2000 Plan, fair market value is defined  as the closing price of a share of the common
stock on the Nasdaq Global Select Market as of  any applicable date, as long  as the Company’s shares
are traded on such exchange.

Grant-Date Fair Value

For the purpose of valuing stock options, the Company  uses  the  Black-Scholes option pricing
model to calculate the grant-date fair  value of an award. The  fair values of options granted were
calculated using the following estimated weighted-average assumptions:

Expected volatility—The Company is  responsible for estimating volatility  and has considered a
number of factors  when estimating volatility. The Company’s  method of estimating expected volatility
for all stock options granted relies on  a combination of historical and implied volatility. The Company
believes that this blended volatility results in a more accurate estimate of the grant-date fair  value of
employee stock options because it more  appropriately reflects the  market’s  current expectations  of
future volatility.

Expected term—Weighted average expected term  was  calculated  using a forward looking  lattice

model of the Company’s stock price  incorporating a  suboptimal exercise  factor and  a projected
post-vest forfeiture rate.

Risk-free interest rate—The yield on  zero-coupon U.S.  Treasury securities for a period that is

commensurate with the expected term  assumption  is used as the risk-free  interest rate.

Expected dividend yield—Expected dividend  yield was  not  considered in  the option  pricing formula

since the Company does not pay dividends  and has no current plans to do so  in the future.

Stock-Based Compensation Expense

The Company estimates the fair value  of  stock options using  the Black-Scholes valuation model.
The fair value of the Company’s restricted  stock  and  restricted  stock units  is calculated  based upon the
fair market value of the Company’s stock at  the date  of grant.

The Company uses the straight-line attribution method  to  recognize expense  for stock-based
awards such that the expense associated  with awards is evenly recognized throughout the  period.

The amount of stock-based compensation recognized is based on the  value  of  the portion of the
awards that are ultimately expected to  vest. The Company estimates  forfeitures at  the time  of grant and
revises them, if necessary, in subsequent  periods if actual forfeitures differ from those estimates.  The
term ‘‘forfeitures’’ is distinct from ‘‘cancellations’’ or  ‘‘expirations’’  and represents only the  unvested
portion of the surrendered stock-based award. The Company currently expects,  based on a historical
analysis, a forfeiture rate of 5% per year, including executive officer awards.

F-16

The Company recognized stock-based compensation expense of  $4.7 million, $4.1 million and
$4.7 million for the years ended December 31,  2011, 2010 and 2009,  respectively. For 2011, 2010  and
2009, the Company primarily used stock  options  in its  annual share-based payment  program.

The benefits of tax deductions in excess of  recognized compensation cost is reported  as a financing

cash flow, rather than as an operating cash  flow. Because  the Company  does not recognize the  benefit
of tax deductions in excess of recognized  compensation  cost due to its  cumulative net  operating loss
position, this had no impact on the Company’s consolidated statement of  cash flows as of and for the
years ended December 31, 2011, 2010 and 2009.

(1) In addition to the vested options, the  Company expects  a portion  of the unvested  options to vest at
some point in the  future. Options expected  to  vest is calculated  by applying an estimated forfeiture
rate to the unvested options.

Of the options outstanding at December  31, 2011,  2010, and 2009, 10,205, 8,443,  and 9,335,
respectively, were vested and exercisable  with a weighted average exercise price  of  $4.13, $6.68, and
$11.12, respectively. The total intrinsic value of options  exercised (i.e.  the difference  between  the
market price at exercise and the price  paid by the  employee  to  exercise the options) for  the years
ended December 31, 2011, 2010 and 2009 was $0.7,  $1.2 and $0.8 million, respectively.

F-17

The total fair value of stock options  vested during the year ended December 31, 2011  was

$3.3 million. As of December 31, 2011, there was $9.5  million of total forfeiture adjusted unrecognized
compensation cost related to non-vested stock options granted under the 2000 Plan. That cost  is
expected to be recognized over a weighted-average period of 2.8 years.

Restricted Stock and Restricted Stock Units

Restricted stock units (‘‘RSUs’’) represent  the Company’s unfunded and unsecured promise to
issue shares of the common stock at  a future date,  subject to the terms  of  the RSU  Award Agreement
and the 2000 Plan. The purpose of these awards is to assist in  attracting and retaining  highly competent
employees and directors and to act as an  incentive in motivating  selected  employees and directors to
achieve long-term corporate objectives.  These RSU awards typically vest over four years for employees
and executive officers. The restricted  stock awards to directors typically vest over  six months. The fair
value of restricted stock unit and restricted stock awards  is charged to expense  ratably over the
applicable service period.

Changes in the Company’s non-vested  restricted stock and restricted stock units for the years

ended December 31, 2011, 2010, and  2009 are as follows:

The company’s offers a net share settlement program to offset the  personal  income  tax obligations
of the employee’s  restricted stock vesting. Vesting  activity above reflects  shares vested before net share
settlement. As of December 31, 2011, there was $0.3 million of  total  forfeiture  adjusted unrecognized
compensation cost related to nonvested restricted stock and  restricted stock units, which is expected to
be amortized over a weighted average  amortization period  of 2.99 years.

Employee Stock Purchase Plan

The Employee Stock Purchase Plan (the ‘‘Purchase Plan’’) provides effectively all Axcelis
employees the opportunity to purchase  common stock  of  the  Company at  less  than market prices.
Purchases are made through payroll deductions of up to 10%  of  the employee’s  salary, subject to
certain caps set forth in the Purchase  Plan. Employees may purchase Axcelis common  stock  at 85% of
the market value of the Company’s common stock on the day the stock is purchased.

F-18

The Purchase Plan is considered compensatory and  as such, compensation expense  has been
recognized based on the benefit of the discounted  stock price, amortized  to compensation expense over
each  offering period of six months. Compensation  expense for the years ended December 31, 2011,
2010, and 2009 was $0.1 million, $0.1 million, and $0.0  million respectively.

As of December 31, 2011, there were  a total of 2.3  million shares reserved for issuance and
available for purchase under the Purchase Plan. There  were  0.4, 0.3, and  0.3  million  shares purchased

At December 31, 2011, the Company had $130.0 million of deferred tax assets relating to net
operating loss carryforwards, tax credit  carryforwards and other temporary differences, which are
available to reduce income taxes in future  years.  A valuation allowance must be established  when it is
‘‘more likely than not’’ that all or a portion  of  deferred tax assets will  not  be  realized. A review of all
available positive and negative evidence  needs to be considered, including a company’s  performance,
the market environment in which the company operates length  of carryback and carryforward  periods,
existing sales backlog, and projections  of  future  operating results. Where there are cumulative losses in

F-22

recent years there is a strong presumption that a valuation allowance is needed.  This presumption  can
be overcome in very limited circumstances.

The Company is in a three year cumulative  loss position in the  United States. As a result,  the
Company maintains a 100% valuation allowance for  entities  in those  tax  jurisdictions to reduce the
carrying  value of deferred tax assets to  zero. The  Company will continue to maintain a  full valuation
allowance for those tax assets until sustainable future levels  of profitability  are evident.

Changes in the valuation allowance in 2011 and 2010  were  attributable  to  changes in the
composition of temporary differences  and changes  in net operating loss  carryforwards. In addition,
during 2010 the Company performed  an  evaluation  of  the deferred tax  assets of certain of its foreign
subsidiaries. Based on the subsidiaries  recent and expected ability  to  generate  taxable income, the
Company reduced the subsidiaries’ corresponding valuation allowance and recognized a tax benefit of
$1.3 million.

At December 31, 2011, the Company has federal and state net operating  loss carryforwards of
approximately $227.9 million and foreign net operating  loss carryforwards of approximately $4.5  million
expiring principally between 2021 and 2030.

The Company has research and development and other tax  credit carryforwards of approximately

$19.0 million at December 31, 2011 that can be used to reduce future federal and  state income tax
liabilities. These tax credit carryforwards expire  principally between 2021  and 2031.  In  addition, the
Company has foreign tax credit carryforwards of  approximately $5.6  million  at December 31, 2011  that
are available to reduce future U.S. income tax liabilities subject to certain  limitations. These foreign tax
credit carryforwards expire between 2012 and 2016.

It  is Company policy to provide taxes for the total anticipated  tax impact  of the undistributed
earnings of our wholly-owned foreign  subsidiaries’, as such earnings  are  not expected  to  be  reinvested
indefinitely. The Company anticipates that  US tax resulting from remitting such earnings will be off-set
by net operating loss or credit carryforwards to the extent  available. In  addition,  the Company does not
anticipate incurring a foreign withholding  tax on remitting such earnings since it does not intend  to
remit the earnings as dividends.

The Company and its subsidiaries file income tax returns in  the U.S. federal jurisdiction and
various states and foreign jurisdictions. The Company and most foreign  subsidiaries are subject to
income tax examinations by tax authorities  for all years dating  back to 2001. The  Company’s policy is to
recognize interest related to unrecognized tax benefits as  interest  expense and penalties as operating
expenses. The Company believes that it  has appropriate  support for the income tax  positions  taken and
to be taken on its tax returns and that  its accruals for tax liabilities are adequate for all open years
based on an assessment of many factors including past experience  and interpretations of tax law applied
to the facts of each matter.

At December 31, 2011, the Company had unrecognized tax benefits  of approximately  $8.0 million,

of which approximately $4.8 million reduced the  Company’s deferred  tax  assets and the offsetting
valuation allowance and $3.2 million was  recorded  in other  long-term  liabilities. The Company does not
expect any significant changes in unrecognized tax benefits in  2012.

Note 17. SEN

Until March 30, 2009, the Company  owned 50%  of the equity of a joint venture with Sumitomo

Heavy Industries, Ltd. (‘‘SHI’’) in Japan. This joint  venture, which was known as SEN was  established
in 1982 and licensed technology from  the  Company relating to the manufacture of specified ion
implantation products and had exclusive rights to manufacture  and sell these products in the  territory
of Japan. On March 30, 2009, pursuant  to  a Share Purchase Agreement  dated February  26, 2009, the
Company sold to SHI all of the Company’s  common shares in SEN in exchange for a cash payment of
13 billion Yen, which resulted in proceeds  of  approximately  $132.8 million before  advisor fees and
other expenses of $10.6 million. The  sales price was determined through an arm’s length negotiation.
This transaction terminated all prior agreements among the  three parties  relating to the SEN joint
venture. In addition, an arbitration the Company  had  initiated  against SEN in  Tokyo was dismissed.

In connection with the sale of the Company’s investment in SEN, on March 30, 2009, the

Company and SEN entered into a License Agreement pursuant to which  the parties have  cross licensed
each  other to use certain ion implant patents and technical  information on a  non-exclusive,  perpetual,
royalty-free, worldwide basis, provided that both  received  sole  exclusive  licenses for 4  years  in the U.S.
and Japan, respectively. The licenses to  technical information cover  only technical information shared
by the parties prior to the date of the  license, so  the license to SEN does not cover technical
information relating to the Optima HD  and Optima XE. The license also  excludes  patents  relating to
the Company’s work in molecular implant and certain patents developed  for the Optima  HD  and
Optima XE. The parties provided each  other with limited warranties  regarding their right to grant
these licenses, and indemnity with respect  thereto,  but disclaim any warranty regarding the  validity  or
freedom from infringement of the licensed intellectual property. Neither party  will  provide any  support
for the other party’s use of the licensed  intellectual property.

The sale of the Company’s investment in SEN on March 30,  2009, resulted  in a gain of

approximately $1.1 million. This gain includes net proceeds of $122.2 million (after payment of advisor
fees and other costs of $10.6 million) and cumulative foreign translation gain of $23.5 million,
previously recorded in other comprehensive income, reduced by  the carrying  value of  the investment on
the date of sale of $144.6 million. The  gain from  the sale of the Company’s investment in  SEN  is
recorded  in other income.

Results of operations for the quarters ended  December 31, 2011 include a tax expense  of

$0.9 million related to an uncertain tax  position in a  certain foreign  jurisdiction. Results of operations
for the quarter ended December 31,  2010 include a  tax benefit  of  $1.3 million related to the  restoration
of deferred tax assets in certain foreign jurisdictions.

Note 19. Subsequent Events

In order to align manufacturing and operating expense levels to changing business conditions, the

Company implemented a headcount reduction of  approximately 9% in  the first quarter of 2012. This
action is expected to generate savings  in the range  of $8 million  to  $12 million annually. The Company
anticipates recording employee termination benefits and other  related costs  of $2.5 million to
$3.5 million during the first and second  quarters of 2012.

SAFE HARBOR STATEMENT
This document contains forward-looking statements under the SEC safe harbor provisions.  These statements are based on management’s current expectations and should be
viewed  with  caution.    They  are  subject  to  various  risks  and  uncertainties,  many  of  which  are  outside  the  control  of  the  company,  including  our  ability  to  implement 
successfully  our  profit  plans,  the  continuing  demand  for  semiconductor  equipment,  relative  market  growth,  continuity  of  business  relationships  with  and  purchases  by 
major  customers,  competitive  pressure  on  sales  and  pricing,  increases  in  material  and  other  production  costs  that  cannot  be  recouped  in  product  pricing  and  global 
economic and financial conditions.
