Overview of Our Business 

PART I 

Axcelis Technologies, Inc. (“Axcelis,” the “Company,” “we,” “us,” or “our”) designs, manufactures and 
services ion implantation and other processing equipment used in the fabrication of semiconductor chips. We believe that 
our Purion family of products offers the most innovative implanters available on the market today. We sell to leading 
semiconductor chip manufacturers worldwide. The ion implantation business represented 95.3% of our revenue in 2018, 
with the remaining 4.7% of revenue derived from other legacy processing systems. In addition to equipment, we provide 
extensive aftermarket lifecycle products and services, including used tools, spare parts, equipment upgrades, 
maintenance services and customer training. 

Axcelis’ business commenced in 1978 and its current corporate entity was incorporated in Delaware in 1995. 
We are headquartered in Beverly, Massachusetts and maintain an internet site at www.axcelis.com. On or through our 
website, investors may access, free of charge, 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. 

Despite a significant slowdown in memory spending in the second half of 2018, revenue increased by nearly 8% 
over 2017, with systems revenue increasing by 6.7%, and revenues from Customer Support & Innovation (“CS&I”), our 
aftermarket business, increasing by nearly 10%.  2018 full year gross margin exceeded 40% and cash increased by 33% 
to $178.0 million. 

Our 2018 results were the product of hard work across the Company over prior years to expand the Purion 

install base to a large and diverse group of customers. We have focused on key markets in the mature process technology 
sector such as image sensor, power device and mature foundry and logic. We developed Purion product extensions 
specifically for these markets and becoming key partners with these customers.  As a result, our fourth quarter 2018 
revenues showed a split of 68% mature process technology and 32% memory, illustrating our expansion into the mature 
process technology sector, and the reduction in our dependence on memory customers.  For the full year the mix was 
54% mature process technology and 46% memory.  

We continue to work diligently to ensure that manufacturing and operating expense levels remain well aligned 

to business conditions. We believe that the most fundamental interest of our stockholders is consistent, profitable, 
financial performance, which we expect to continue to deliver in 2019. Our performance is subject to risks and 
uncertainties discussed below under Item 1A Risk Factors. 

Industry Overview 

Semiconductor chips, also known as integrated circuits, are used in a continuously evolving range of consumer 
and industrial products, including for example, personal computers, mobile devices, automobiles, sensors and controllers 
for the “internet of things,” and data storage servers. Types of semiconductor chips include dynamic random-access 
memory (“DRAM”) and “negative and” (“NAND”) Flash memory; logic devices to process information; and “system on 
chip” devices (which have both logic and memory features). The increased number of devices providing information to 
and receiving information from the Internet, sometimes referred to as the “Connected World,” is increasing demand for 
chips. These chips are used in data input, such as image sensors, which are often manufactured using mature processing 
technologies, as well as for memory chips to support the storage of data, internet streaming and “cloud computing” data 
analytics. 

Most semiconductor chips are built on silicon wafers 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 

2 

 
 
 
 
 
 
 
 
 
 
device. Transistors are created in the silicon wafer by introducing various precisely placed impurities into the silicon in 
specific patterns.  

Semiconductor chip manufacturers own or manage wafer fabrication facilities (often referred to as “fabs”), 

which 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 device performance benefits through new products and technology enhancements and productivity 
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.  

We have different types of customers, which impacts timing of purchases and technology requirements. Some 

customers are integrated electronics manufacturers, making semiconductor chips for their own devices.  These same 
companies may also act as foundries, manufacturing chips for other electronic manufacturers or chip design companies.  
Some customers only function as foundries.  A few companies design and manufacture branded chips that are sold to 
device manufacturers.  In addition, some customers have partnerships or joint ventures with two or more semiconductor 
chip manufacturers to share the technology development and capital investment.  The timing of purchases by foundry 
customers will depend on their success in securing manufacturing contracts.  Also, foundry customers will look for 
equipment that can deliver the broadest capabilities in order to be prepared to manufacture all chip types, while 
integrated electronics manufacturers may invest in processing equipment dedicated to a specific application they require 
for their products. 

The semiconductor capital equipment industry is 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 through 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. Device 
manufacturers react with muted capital spending, lowering the demand for capital equipment. Changes in consumer and 
business demand for products in which chips are used also affect the industry. A successful semiconductor capital 
equipment manufacturer must not only provide some of the most technically complex products manufactured in the 
world but also must manage its business to thrive during low points in the cycle. 

Axcelis’ Strategy 

Axcelis’ 2019 strategic initiatives are: 

•  Continue to expand our Purion footprint within our existing customer base 
•  Penetrate Japanese and advanced foundry/logic markets with Purion 
•  Capitalize on successful market segmentation strategy by releasing new Purion product extensions focused on 

key market segments 

•  Drive Customer Support & Innovation revenues by delivering excellent customer service and innovative, high 

value products and services 

•  Deliver gross margins of 41% for full year 2019  

We continue to invest in research and development to ensure our products meet the needs of our customers. We 

take pride in our scientists and engineers who are adding to our portfolio of patents and unpatented proprietary 
technology to ensure that our investment in technology leadership translates into unique product advantages. We strive 
for operational excellence by focusing on ways to lower our product, manufacturing and design costs and to improve our 
delivery times to our customers. Global Customer Teams and a focused account management structure maintain and 
strengthen our customer relationships and increase customer satisfaction. Finally, we endeavor to maintain a strong cash 
balance to ensure sufficient capital to fund business growth.

Ion Implantation Systems 

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

process. Ion implantation is also used to change the material characteristics of the silicon for reasons other than electrical 
doping, a process known as “material modification.” An ion implanter is a large, technically advanced system that injects 
dopants such as arsenic, boron or phosphorus into a wafer. These dopants are ionized and therefore have an electrical 
charge state. This electric charge state allows the dopants to be accelerated, focused and filtered with electric and 
magnetic fields. Ion implanters use these fields to create a beam of ions with a precisely defined energy level (ranging 
between several hundred and eight million electron-volts) and with a precisely defined beam current level (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. Typical process 
flows require twenty implant steps, with the most advanced processes requiring thirty or more steps. Each implant step is 
characterized by four key parameters: dopant type, dose (amount of dopant), energy (depth into the silicon) and tilt/twist 
(angle of wafer relative to the ion beam). 

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

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

•  High energy implanters emerged to address the need for deeper implants with a high energy range and low 

dose. 

•  Medium current implanters are the original model of ion implanter, with mid to low-range energy and dose 

capability. 

•  High current implanters were the second type of implanter to emerge, having low energy capability and 

high dose range. 

The Purion Platform and Family of Ion Implanters 

Axcelis offers a complete line of high energy, high current and medium current implanters for all application 
requirements. Our Purion flagship systems are all based on a common platform which enables a unique combination of 
implant purity, precision and productivity. Combining a state-of-the-art single wafer end station, with advanced spot 
beam architectures (that ensures all points across the wafer see the same beam condition at the same beam angle), Purion 
products enable exceptional process control to optimize devise performance and yield, at high productivity. 

•  High Energy Implant.  Our Purion XE high energy system combines Axcelis’ production-proven RF 
Linac high energy, spot beam technology with the Purion platform wafer handling system. Axcelis is a 
market leader in high energy ion implanters, and we expect to maintain our leadership in the high energy 
segment through sales of both our legacy multi-wafer high energy systems and the Purion XE, the Purion 
EXE and the Purion VXE.  

•  Medium Current Implant.  Our Purion M medium current system offers higher productivity and lower 
electrical energy consumption compared to competitive offerings, in addition to other advantages. Our 
Purion M systems also offer differentiated capabilities for specialty applications. 

•  High Current Implant.  Our Purion H spot beam, high current system covers all traditional high current 
requirements as well as those associated with emerging and future devices. Purion H capabilities extend 
beyond traditional high current energy and dose ranges, in order to cover new device fabrication 
requirements as well as to maximize capital utilization and flexibility. In addition, Purion H provides 
advantages for material modification applications, including those requiring hot and cold implant 
capabilities.

We believe our ion implant products will continue to meet customer demand for advantages in productivity, 

process performance and technical extendibility.  

Aftermarket Support and Services 

Through our Customer Support and Innovation (“CS&I”), business, we offer our customers extensive 

aftermarket service and support throughout the lifecycle of the equipment we manufacture. We believe that 
approximately 3,200 of our products are in use in 31 countries worldwide. The service and support that we provide 
includes used tools, spare parts, equipment upgrades, and maintenance services. We offer varying levels of sales, service 
and applications support out of our field offices to customers located in 31 countries. Revenue generated through our 
CS&I business represented 36.6%, 36.0% and 47.8% of revenue in 2018, 2017 and 2016, respectively. 

To support our aftermarket business, we have 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.  

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. These services provide 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 conduct sales and marketing 
activities from our sales offices located in the United States, Taiwan, South Korea, China, Germany, Singapore, Japan 
and Italy. In February 2018, we entered into a distribution and service agreement with SCREEN Semiconductor 
Solutions, a subsidiary of SCREEN Holdings Co. Ltd., for our Purion ion implant product line in Japan. 

International revenue, including export sales from our U.S. manufacturing facilities to foreign customers and 
sales by foreign subsidiaries and branches, accounted for 87.7%, 84.9% and 80.0% of total revenue in 2018, 2017 and 
2016, respectively. Substantially all of our sales are denominated in U.S. dollars. See Note 17 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. See also Item 1A, “Risk Factors,” for information about risks attendant to our foreign 
operations. 

Customers 

In 2018, the top 20 semiconductor chip manufacturers accounted for approximately 88.8% of total 

semiconductor capital equipment spending, down from 90.9% in 2017. These manufacturers are from the largest 
semiconductor chip manufacturing regions in the world: the United States, Asia Pacific (Taiwan, South Korea, 
Singapore, Japan and China) and Europe.  

Information on net sales to unaffiliated customers is included in Note 2 of Notes to Consolidated Financial 

Statements. For the year ended December 31, 2018, revenues from each of Samsung Electronics Co, Ltd., and SK hynix 
represented 10 percent or more of consolidated revenues and the loss of these customers would have a material adverse 
effect on our business.  

Research and Development 

Our industry continues to experience rapid technological change, requiring us to frequently introduce new 

products and enhancements. Our Beverly, Massachusetts Advanced Technology Center houses a process development 

5 

 
 
 
 
 
 
 
 
 
 
 
 
 
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 environments. This facility also provides significant capability for our research and 
development efforts. 

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 use 3D, computer-aided design, finite element analysis and other computer-based modeling 
methods to test new designs. 

Our expenses for research and development were $51.9 million, $43.1 million and $34.4 million in 2018, 2017 
and 2016, respectively, or 11.7%, 10.5% and 12.9% of revenue, respectively. We expect that research and development 
expenditures will continue to represent a similar level of investment in future years. 

Manufacturing 

We manufacture products at our 417,000 sq. ft. ISO 9001:2015, ISO 14001:2015 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 1,000/10,000 space to facilitate most of our manufacturing 

requirements. 

Our core competency in manufacturing and supply chain management is built around system assembly and 

testing, 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 vacuum 
systems, wafer handling and commodity-level components. We continuously pursue outsourcing opportunities where the 
economics are justified, with a goal of enabling 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 assembling the 

equipment at our installation site, and after it has been connected, recalibrating it to factory specifications. 

Competition 

The semiconductor industry is highly competitive and is characterized by a small number of participants 

ranging in size. Significant competitive factors in the semiconductor capital equipment market include price, cost of 
ownership, equipment performance, customer support, capabilities and breadth of product line. 

In ion implantation, we mainly compete against Applied Materials, Inc. Applied Materials and Axcelis are the 

only ion implant manufacturers with a full range of implant products, and service and support infrastructures able to 
service our customers globally. Three other niche players we compete with from time to time include Advanced Ion 
Beam Technology, Inc., Nissin Ion Implantation Co., Ltd. and Sumitomo Heavy Industries Ion Technology Co., Ltd. 

6 

 
 
 
 
 
 
 
 
 
 
 
Intellectual Property 

We rely on patent, copyright, trademark and trade secret protection in the United States and in other countries, 

as well as contractual restrictions, to protect our proprietary rights in our products and our business. As of January 1, 
2019, we had 243 active patents issued in the United States and 491 active patents granted in other countries, as well as 
216 patent applications (48 in the United States and 168 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. Trademark registrations generally remain in effect as long as the trademarks are in use. 
From time to time, we enter into license agreements with third parties under which we obtain or grant rights to patented 
or proprietary technology. We do not believe that any of our licenses are currently material to us.  

Backlog 

Systems backlog, including deferred systems revenue, was $65.1 million and $87.3 million as of December 31, 
2018 and 2017, respectively. 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 
or customer prepayments. Our policy is to include in backlog only those system orders for which we have accepted 
purchase orders and are typically due to ship within six months. All orders are subject to cancellations or rescheduling by 
customers with limited or no penalties. 

Backlog does not include orders received and fulfilled within a quarter. Our backlog at the beginning of a 
quarter typically does not include all orders required to achieve our sales objectives for that quarter. Backlog is not 
necessarily an indicator of future business trends because orders for services or parts received during the quarter are 
generally performed or shipped within the same quarter. 

Bookings in the quarter ended December 31, 2018 were $42.1 million compared to $103.8 million in the quarter 

ended December 31, 2017. 

Employees 

As of December 31, 2018, we had 992 employees and 87 temporary staff worldwide, of which 761 work in 

North America, 261 in Asia and 57 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 are proud of our commitment to improving our environment. We believe 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 9001:2015 and ISO 14001:2015 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. It is not possible to predict or identify all such risk factors. Consequently, the 
following is not a complete discussion of all potential risks or uncertainties. 

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

New systems orders and used tool sales depend upon demand from semiconductor chip 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. In addition, all or a portion of the demand for increased 
capacity may be satisfied by a semiconductor chip manufacturer’s ability to reconfigure and re-use equipment they 
already own.  Revenue decline also hurts our profitability because our established 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.  

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

Rapid technological changes in semiconductor chip 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. This will depend upon a variety of 
factors, including new product selection, timely and efficient completion of product design and development as well as 
manufacturing and assembly processes, product performance in the field and effective sales and marketing. In particular: 

•  We must continue to develop competitive technical specifications for new systems, or enhancements to our 
existing systems, and manufacture and ship these systems or enhancements in volume in a timely manner. 

•  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. 

•  We will need to effectively manage product reliability or quality problems that often exist with new 

systems, in order to avoid higher manufacturing costs, delays in acceptance and payment and additional 
service and warranty expenses, and ultimately, a lack of repeat orders. 

•  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. 

A significant portion of our revenue depends on customers electing to buy aftermarket products and services from 
Axcelis. 

Historically, a significant portion of our product revenue and all of our service revenue relates to our sale of 

“aftermarket” products and services, which include parts, consumables, upgrades, service contracts, and time and 
materials billings. Some of our customers purchase fewer aftermarket products and services, often training their own 
staff to maintain and service semiconductor capital equipment rather than relying on the equipment manufacturer for 
these services. In addition, we compete against third party parts suppliers for the sale of parts and consumables that are 

10 

 
 
 
 
 
 
 
 
 
 
 
 
 
not protected by patents or otherwise proprietary. To the extent our customers purchase parts and services from other 
vendors or provide their own system maintenance labor, our revenue and profitability will be less. 

Our financial results may fluctuate significantly. 

We derive our new systems revenue from the sale of a small number of expensive products to a relatively small 
number of customers. The selling prices on our ion implant and other systems range from approximately $2.0 million to 
$8.0 million. We also sell used equipment in our aftermarket business. Each sale, or failure to make a sale, may have a 
significant 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, warranty costs and impact of changes to inventory 
reserves. New product introductions may also affect our gross margin. 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 because forecasting revenue and profitability is complex and 
may be inaccurate. 

Management may from time to time provide financial forecasts to investors. These forecasts are based on 

assumptions, which are believed to be reasonable when made, of the timing of system orders, system shipments, system 
acceptance and aftermarket revenue. Any of these assumptions can prove erroneous and 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 revenue 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 systems 
on previous orders as scheduled during that quarter, receiving customer acceptance of previously shipped products, and 
obtaining new orders for products and services to be provided in that same quarter. Any delay in, or cancellation of, 
scheduled shipments and customer acceptances or in revenue from new orders, including aftermarket revenue, could 
materially affect our financial results. 

Accounting rules addressing revenue recognition add more complexity in forecasting quarterly revenue and 
profitability. Orders for our products usually contain multiple performance obligations 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 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 cyclical and we expect that demand for our products will increase and decrease, 
making it difficult to manage the business and potentially causing harm to our sales and profitability. 

The semiconductor industry is 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, produce an oversupply of semiconductors. This can cause a reduced demand for 
capital equipment such as our products, negatively impacting our sales and level of profitability. 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 do not fluctuate with 
changes in volume. Significant decreases in revenue can therefore have a disproportionate effect on profitability. In 
addition, reduced demand for our products and services may require Axcelis to implement cost reduction efforts, 
including restructuring activities, which may adversely affect Axcelis’ ability to capitalize on opportunities that arise in 
the future. 

11 

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

The ion implant segment is highly competitive and includes one company with substantially greater financial, 

engineering, manufacturing, marketing and customer service and support resources that may better position it to compete 
successfully, as well as several smaller companies that could provide innovative systems with technology that may have 
performance advantages. 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. Finally, if we must lower prices to remain competitive without commensurate cost of goods 
savings, our gross margin and profitability will be adversely affected. 

We are dependent on sales to a limited number of large customers; the loss of a significant customer 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 

semiconductor chip manufacturers. In 2018, our top ten customers accounted for 76.9% of our net sales, in comparison to 
73.3% and 70.2% in 2017 and 2016, respectively. None of our customers have 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 
will adversely affect us. Consolidation of semiconductor chip manufacturers may result in the loss of a customer. 

Axcelis is subject to the risks of operating internationally: 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, accounted for 87.7% of total revenue in 2018 in comparison to 84.9% of total revenue in 2017 and 
80.0% in 2016. Ion implanter system shipments to Asian customers represented 86.6% of total system shipment dollars 
in 2018 in comparison to 82.6% in 2017 and 75.3% in 2016. We anticipate that international sales will continue to 
account for a significant portion of our revenue. The potential increased investment in semiconductor chip manufacturing 
capability in China is expected to result in both risk and opportunity. Because of our dependence upon international 
sales, our results and prospects may be adversely affected by a number of factors, including: 

• 

• 

• 

• 

• 

• 

• 

• 

unexpected changes in laws or regulations resulting in more burdensome governmental controls, tariffs, 
restrictions, embargoes or export license requirements; 

volatility in currency exchange rates; 

political and economic instability; 

difficulties in accounts receivable collections; 

extended payment terms beyond those customarily offered in the United States; 

difficulties in managing suppliers, service providers or representatives outside the United States; 

difficulties in staffing and managing foreign subsidiary operations; and 

potential adverse tax consequences. 

12 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
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 insufficient levels of staffing to fully 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 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 a limited group of suppliers. 
Accordingly, based on situations outside of our control, 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, 
negatively impacting our gross margin. 

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

requires long lead times. As a result we could 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 systems on a timely 
basis, causing us to lose sales, incur additional costs, delay new product introductions and suffer harm to our reputation. 

Moreover, if actual demand for Axcelis’ products is different than expected, Axcelis may purchase more or 

fewer parts than necessary or incur costs for canceling, postponing or expediting delivery of parts. If Axcelis purchases 
inventory in anticipation of customer demand that does not materialize, or if customers reduce or delay orders, Axcelis 
may incur excess inventory charges. 

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. However, the aftermarket revenues of our non-U.S. subsidiaries, and most of the operating 
expenses of these non-U.S. subsidiaries, are received and incurred in local currencies.  The translation of these operating 
results into U.S. dollars in our Consolidated Statement of Operations can result in other income (expense).  Similarly, the 
translation of asset and liability values to U.S. dollars are recorded in stockholders’ equity as an element of accumulated 
other comprehensive income (loss).  Accordingly, fluctuations in exchange rates can impact reported revenues, expense, 
and profitability and asset values in our Consolidated Financial Statements. During the year ended December 31, 2018, 
approximately 22.5% of our revenue was derived in local currencies from foreign operations with this inherent risk. In 
addition, at December 31, 2018, our operations outside of the United States accounted for approximately 12.9% of our 
total assets, the majority of which was denominated in currencies other than the U.S. dollar.  

Axcelis is exposed to risks related to cybersecurity threats and incidents. 

In the conduct of our business, Axcelis collects, uses, transmits and stores data on information technology 
systems. This data includes confidential information belonging to Axcelis, our employees or our customers or other 
business partners, some of which is personally-identifiable information of individuals. As reported in the 2017 Verizon 
Data Breach Investigation Report, attempts to access confidential business information make up almost all of the cyber 

13 

 
 
 
 
 
 
 
security risk for a manufacturing company, with 93% of the threat actors external to the targeted company.  Verizon 
reported that most of the attacks are conducted by state-affiliated actors who are an “advanced persistent threat.”  Axcelis 
has been and expects to be subject to cybersecurity threats and incidents, including employee error or misuse; individual 
attempts to gain unauthorized access to information systems; and sophisticated and targeted measures known as 
advanced persistent threats, none of which have had a material impact on the Company to date. Axcelis devotes 
significant resources to network security, data encryption, employee training and other measures to protect our systems 
and data from unauthorized access or misuse. However, depending on their nature and scope, cybersecurity incidents 
could result in business disruption; the misappropriation, corruption or loss of confidential information and critical data 
(Axcelis’ and that of third parties); reputational damage; litigation with third parties; diminution in the value of Axcelis’ 
investment in research, development and engineering; data privacy issues; and increased cybersecurity protection and 
remediation costs. These adverse outcomes could negatively impact our revenues, expenses, profitability and asset 
values. 

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 challenge, design around or legitimately use the proprietary 
technology embedded in our systems or other technology or information used in our business. If this occurs, the value of 
our proprietary technology will be diminished. Our means of protecting our proprietary rights may not be adequate and 
our patents may not be sufficient to prevent others from using technology that is similar to or the same as our technology. 
Patents issued to us may 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 invalidation or 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 or claims of infringement with respect to such 
technology could have an adverse impact on our financial performance or ability to ship products with existing 
configurations. 

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 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 may 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 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 remove certain features from our products or seek costly licenses from third parties or 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. 

14 

 
 
 
 
 
 
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. Our 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. 

If we do not have access to capital on favorable terms, on the timeline we anticipate, or at all, our financial condition 
and results of operations could be materially adversely affected.  

We require a substantial amount of capital to meet our operating requirements and remain competitive. We 
routinely incur significant costs to purchase inventory to meet expected system sales, to develop and introduce new 
products, and to place evaluation systems at new customer sites.  Our Board has also authorized management to 
repurchase shares of our common stock under a one year stock repurchase program.  There can be no assurance that we 
will realize a return on the capital expended. Although our current cash levels are expected to be adequate for our 
foreseeable cash requirements, if our operating results falter, or our cash flow or capital resources prove inadequate, we 
may incur debt to fund these requirements. Significant volatility or disruption in the global financial markets may result 
in us not being able to obtain additional financing on favorable terms, on the timeline we anticipate, or at all, and we may 
not be able to refinance, if necessary, any outstanding debt when due, all of which could have a material adverse effect 
on our financial condition. Any inability to obtain funding on favorable terms, on the timeline we anticipate, or at all, 
may cause us to curtail our operations significantly, reduce planned capital expenditures and research and development, 
or obtain funds through arrangements that management does not currently anticipate, including disposing of our assets 
and relinquishing rights to certain technologies, the occurrence of any of which may significantly impair our ability to 
remain competitive, and materially and adversely affect our results of operations and financial condition.  

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

The stock markets in general, and the markets for semiconductor equipment stocks in particular, have 
experienced extreme volatility that has often been unrelated to the operating performance of particular companies. These 
broad market fluctuations may adversely affect the trading price of our common stock.  
The market price of the common stock may also fluctuate significantly in response to the following factors, among 
others, some of which are beyond our control:  

• 
• 
• 
• 
• 

• 
• 

  variations in our quarterly operating results;  
  the issuance or repurchase of shares of our common stock;  
  changes in securities analysts’ estimates of our financial performance;  
  changes in market valuations of similar companies;  
  announcements by us or our competitors of significant contracts, acquisitions, strategic partnerships, joint 
ventures, capital commitments, new products or product enhancements;  
  loss of a major customer or failure to complete significant transactions; and  
  additions or departures of key personnel.  

The trading price of our common stock in the past has had significant volatility, and we cannot accurately 

predict every potential risk that may materially and adversely affect our stock price.

The semiconductor capital equipment industry is subject to cyclical swings in capital spending by 

semiconductor chip manufacturers. Capital spending is influenced by demand for semiconductors and the products using 
them, the utilization rate and capacity of existing semiconductor chip manufacturing facilities and changes in 
semiconductor technology, all of which are outside of our control. As a result, our revenue may fluctuate from year to 
year and period to period. Our established cost structure does not vary significantly with changes in volume. We may 
also experience fluctuations in operating results and cash flows depending on our revenue level. 

Despite a significant slowdown in memory spending in the second half of 2018, revenue increased by nearly 8% 
over 2017, with systems revenue increasing by 6.7%, and revenues from Customer Support & Innovation (“CS&I”), our 
aftermarket business, increasing by nearly 10%.  2018 full year gross margin exceeded 40% and cash increased by 33% 
to nearly $178 million. 

Our 2018 results were the product of hard work across the Company over prior years to expand the Purion 

install base to a large and diverse group of customers. We have focused on key markets in the mature process technology 
sector such as image sensor, power device and mature foundry and logic. We developed Purion product extensions 
specifically for these markets, becoming key partners with these customers.  As a result, our fourth quarter 2018 
revenues showed a split of 68% mature process technology and 32% memory, illustrating our expansion into the mature 
process technology sector, and the reduction in our dependence on memory customers.  For the full year the mix was 
54% mature process technology and 46% memory. 

We also continued to work diligently to ensure that manufacturing and operating expense levels remain well 

aligned to business conditions.  

The market for our systems and aftermarket products and services is represented by a relatively small number of 

companies.  In 2018, the top 20 semiconductor chip manufacturers accounted for approximately 88.8% of total 
semiconductor capital equipment spending, down from 90.9% in 2017. Our net revenue from our ten largest customers 
accounted for 76.9% of total revenue for the year ended December 31, 2018 compared to 73.3% and 70.2% of revenue 
for the years ended December 31, 2017 and 2016, respectively. For the year ended December 31, 2018, we had two 
customers representing 20.1% and 12.1% of total revenue, respectively.  

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 

18 

 
 
 
 
 
 
 
 
 
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 Note 2 to the consolidated financial statements for the year 
ended December 31, 2018 included in this Annual Report on Form 10-K.  

Revenue Recognition 

Our accounting policies relating to the recognition of revenue require management to make estimates, 

determinations and judgments based on historical experience and on various other assumptions, which include (i) the 
existence of a contract with the customer, (ii) the identification of the performance obligations in the contract, (iii) the 
value of any variable consideration in the contract, (iv) the stand alone selling price of multiple obligations in the 
contract, for the purpose of allocating the consideration in the contract, and (v) determining when a performance 
obligation has been met.   Our revenue recognition policies are set forth in section (i) of Note 2, Summary of Significant 
Accounting Policies, to the consolidated financial statements for the year ended December 31, 2018 included in this 
Annual Report on Form 10-K. Recognition of revenue based on incorrect judgments, including an erroneous allocation 
of the estimated sales price between the units of accounting, could result in inappropriate recognition of revenue, or 
incorrect timing of revenue recognition, which could have a material effect on our financial condition and results of 
operations. 

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. 

Actual performance could be materially different from our current forecasts, which could impact 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. 

We did not record an impairment charge in the years ended December 31, 2018, 2017 or 2016. 

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 
collectability 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—Provision for Excess and Obsolescence and Lower of Cost or Net Realizable Value 

We record a provision for estimated excess and obsolete inventory and lower of cost or net realizable value. The 

provision 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 determine that inventory needs 

19 

 
 
 
 
 
 
 
 
 
 
 
 
to be written down, we will recognize such costs in our cost of revenue at the time of such determination. If 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 relative 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. 

Stock-based Compensation 

Stock-based compensation expense for equity awards with service-based conditions is estimated as of the grant 
date based on the fair value of the award and is recognized as expense over the requisite service period, which generally 
equals the vesting period, based on the number of awards that are expected to vest. The fair value of restricted stock unit 
grants is determined using the closing price of our common stock on the date of grant. In contrast, estimating the fair 
value for stock options requires judgment, including the expected term of our stock options, volatility of our stock, 
expected dividends, risk-free interest rates over the expected term of the options and the expected forfeiture rate. 

We consider a number of factors when estimating volatility. Our method of estimating expected volatility for all 

stock options granted relies on a combination of historical and implied volatility. We believe 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. 

We may issue stock option grants with vesting based on performance or market conditions, such as the price of 

our common stock, or, a combination of time, performance or market conditions. The fair values and derived service 
periods for all grants that have vesting based on performance or market conditions are estimated using the Monte Carlo 
valuation method. For each stock option grant with vesting based on a combination of time or market conditions, where 
vesting will occur if either condition is met, the related compensation costs are recognized over the shorter of the explicit 
service period or the derived service period. 

We use 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. We estimate forfeitures at the time of grant and revise 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 benefits of tax deductions in excess of recognized compensation cost is reported as a financing cash flow, 

rather than as an operating cash flow.  

Income Taxes 

We record 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 basis, and net operating loss and tax credit carryforwards. 

Our 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 income tax accounting. 

20 

 
 
 
 
 
 
 
 
 
 
 
 
 
We establish a valuation allowance when it is more likely than not that some portion or all of the deferred tax 

assets will not be realized. Significant management judgment is required in determining our provision for income taxes, 
the deferred tax assets and liabilities and any valuation allowance recorded against those net deferred tax assets. 

We evaluate the weight of all available evidence such as historical losses, the expected timing of the reversals of 

existing temporary differences and projected future taxable income 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. 

Our income tax expense includes 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. We recognize accrued interest related to unrecognized tax 
benefits as interest expense and penalties as operating expense.

2018 Compared with 2017 

Product 

Product revenue, which includes new system sales, sales of spare parts, product upgrades and used system sales 

was $415.9 million or 94.0% of revenue in 2018, compared with $387.1 million, or 94.3% of revenue in 2017. The 
increase in product revenue in 2018 was primarily driven by an increase in the number of Purion systems sold. 

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, 2018 and 2017 was $22.6 million and 
$18.1 million, respectively. The increase was primarily due to the increased number of systems sold in the current year. 

Services 

Services revenue, which includes the labor component of maintenance and service contracts and fees for service 

hours provided by on-site service personnel, was $26.7 million, or 6.0% of revenue for 2018, compared with 
$23.4 million, or 5.7% of revenue for 2017. Although services 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. 

2017 Compared with 2016 

Product 

Product revenue was $387.1 million or 94.3% of revenue in 2017, compared with $244.3 million, or 91.5% of 
revenue in 2016. The increase in product revenue in 2017 was primarily driven by an increase in the number of Purion 
systems sold. 

The total amount of deferred revenue at December 31, 2017 and 2016 was $18.1 million and $11.0 million, 

respectively. The increase was primarily due to the increased number of systems sold in the current year. 

Services 

Services revenue was $23.4 million, or 5.7% of revenue for 2017, compared with $22.7 million, or 8.5% of 

revenue for 2016.

Revenue Categories used by Management 

In addition to the line item revenue categories discussed above, management also uses revenue categorizations 

which breakdown revenue into other groupings. Management regularly disaggregates revenue in the following 
categories, which it finds relevant and useful: 

• 

Ion implant revenue separate from revenue from legacy non-implant product lines, given that ion 
implantation systems are critical to our growth and strategic objectives; 

•  Systems and aftermarket revenues, in which “Aftermarkets” is  

A.  the portion of Product revenue relating to spare parts, product upgrades and used systems 

combined with  

B.  Service revenue, which is the labor component of aftermarket revenues; 

Aftermarket purchases reflect current fab utilization as opposed to System purchases which reflect 
capital investment decisions by our customers, which have differing economic drivers;  

•  Revenue by geographic regions, since economic factors impacting customer purchasing decisions may 

vary by geographic region; and 

•  Revenue by our customers’ end markets, since they tend to be subject to different economic 

environments at different periods of time, impacting a customer’s likelihood of purchasing capital 
equipment during any particular period; currently, management uses three end market categories:  
Memory, mature technology processes and leading edge foundry and logic.   

The ion implant and aftermarket revenue categories for recent periods are discussed below.  

2018 Compared with 2017 

Ion Implant 

Revenue from sales of ion implantation products and related service was $421.7 million, or 95.3% of total 

revenue in 2018, compared with $391.1 million, or 95.2%, of total revenue in 2017.  

Aftermarket 

We refer to the business of selling spare parts, product upgrades, and used systems, combined with the sale of 

maintenance labor and service contracts and service hours, as the “aftermarket” business. Revenue from our aftermarket 
business was $162.2 million in 2018, compared to $147.9 million for 2017. Aftermarket revenue generally increases with 
the 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. 

2017 Compared with 2016 

Ion Implant 

Revenue from sales of ion implantation products and related service was $391.1 million, or 95.2% of total 

revenue in 2017, compared with $248.9 million, or 93.2%, of total revenue in 2016.  

Aftermarket 

Revenue from our aftermarket business was $147.9 million in 2017, compared to $127.7 million for 2016.

Product 

Gross margin from product revenue was 43.2% for the twelve months ended December 31, 2018, compared to 
39.3% for the twelve months ended December 31, 2017. The increase in gross margin of 3.9% resulted from improved 
margins on Purion systems and a lower excess reserve for inventory due to a $6.2 million write-down of Legacy 
inventory in 2017.  

Services 

Gross margin from services revenue was 0.6% for the twelve months ended December 31, 2018, compared to 
(8.3)% for the twelve months ended December 31, 2017. The increase in gross margin in the recent period is primarily 
attributable to decreased costs on service contracts. 

2017 Compared with 2016 

Product 

Gross margin from product revenue was 39.3% for the twelve months ended December 31, 2017, compared to 
39.0% for the twelve months ended December 31, 2016. The increase in gross margin of 0.3% resulted from improved 
margins on Purion systems, partially offset by a $6.2 million write-down of Legacy inventory in 2017. 

Services 

Gross margin from services revenue was (8.3)% for the twelve months ended December 31, 2017, compared to 

19.0% for the twelve months ended December 31, 2016. The decrease in gross margin is primarily attributable to 
increased costs on service contracts.

products and enhancement of existing products; and professional fees, travel and depreciation expenses. Personnel costs 
are our largest expense, representing $74.3 million, or 62.1% of our total operating expenses, for the year ended 
December 31, 2018; $64.5 million, or 63.0%, of our total operating expenses for the year ended December 31, 2017; and 
$47.6 million, or 57.5%, of our total operating expenses for the year ended December 31, 2016.

Our ability to remain competitive depends largely on continuously developing innovative technology, with new 
and enhanced features and systems and introducing them at competitive prices on a timely basis. Accordingly, based on 
our strategic plan, we establish annual R&D budgets to fund programs that we expect will drive competitive advantages. 

2018 Compared with 2017 

Research and development expense was $51.9 million in 2018, an increase of $8.8 million, or 20.4%, compared 

with $43.1 million in 2017. The increase was primarily due to increased headcount and to project costs to support 
development of new Purion products and extensions. 

2017 Compared with 2016 

Research and development expense was $43.1 million in 2017, an increase of approximately $8.7 million, or 

25.2%, compared with $34.4 million in 2016. The increase was primarily due to variable incentive plan expense and to a 
lesser extent to increased headcount.

During the year ended December 31, 2016 we recorded $0.3 million to restructuring expense due to a 

consolidation in our customer base. 

Other (Expense) Income 

Other (expense) income consists primarily of interest expense relating to the lease obligation we incurred in 
connection with the 2015 sale of our headquarters facility (“sale leaseback”) and other financing obligations, foreign 
exchange gains and losses attributable to fluctuations of the U.S. dollar against the local currencies of certain of the 
countries in which we operate, as well as interest earned on our invested cash balances.

2018 Compared with 2017 

Income tax expense was $8.8 million for the year ended December 31, 2018 compared to an income tax benefit 
of $83.1 million in the previous year. The income tax expense of $8.8 million in 2018 reflects a net effective tax rate of 
16.1% on our worldwide pre-tax income. The income tax benefit of $83.1 million in 2017 was primarily due to the 
release of our valuation allowance on our deferred tax assets. 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. 

At December 31, 2018, we had $71.9 million of deferred tax assets worldwide relating to net operating loss 

carryforwards, tax credit carryforwards and other temporary differences, which are available to reduce income taxes in 
future years. We have continued to maintain a $6.8 million valuation allowance in the U.S. against certain tax credits and 
state net operating losses due to the uncertainty of their realization based on long-term Company forecasts and the 
expiration dates on these attributes. If future operating results of the U.S. or these foreign jurisdictions significantly 
exceed expectations, it is reasonably possible that there could be a further reduction in the valuation allowance in the 
future. Further reduction of the valuation allowance, in whole or in part, would result in a non-cash income tax benefit 
during the period of reduction. 

2017 Compared with 2016 

Income tax benefit was $83.1 million for the year ended December 31, 2017, compared to $0.1 million income 

tax expense for the year ended December 31, 2016. The income tax benefit of $83.1 million in 2017 was primarily due to 
the release of our valuation allowance on our deferred tax assets. Our income tax expense for the year ended December 
31, 2016 was due to operating results of foreign entities in jurisdictions in Europe and Asia, where we earned taxable 
income.  

Liquidity and Capital Resources 

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

example, our sales and other factors relate to the uncertainties of global economies, including the availability of credit 
and the condition of the overall semiconductor capital equipment industry. Our established cost structure does not vary 
significantly with changes in volume. We experience fluctuations in operating results and cash flows depending on 
fluctuations in our revenue level. 

In 2018, $47.0 million of cash was provided by operating activities. This compares to $56.3 million of cash 

provided by operations in 2017. Cash and cash equivalents at December 31, 2018 was $178.0 million, compared to 
$133.4 million at December 31, 2017. Approximately $16.2 million of cash was located in foreign jurisdictions as of 
December 31, 2018. In addition to the cash and cash equivalent balance at December 31, 2018, we had $6.9 million in 
restricted cash which relates to a $5.9 million letter of credit associated with the security deposit for the lease on our 
corporate headquarters in Beverly, Massachusetts, a $0.8 million letter of credit relating to workers’ compensation 
insurance, a $0.1 million bank guarantee and a $0.1 million deposit relating to customs activity. Working capital at 
December 31, 2018 was $311.8 million. At December 31, 2018, we had no bank debt. 

Capital expenditures were $4.7 million and $7.3 million for the years ended December 31, 2018 and 2017, 

respectively. Total capital expenditures for 2019 are projected to be approximately $14.5 million. Future capital 
expenditures beyond 2019 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. 

Cash provided by financing activities was $1.2 million and $15.1 million for the years ended December 31, 

2018 and 2017, respectively. In both years, the cash provided by financing activities was mainly due to the exercise of 
stock options and proceeds received from the employee stock purchase plan.

We have outstanding letters of credit and surety bonds in the amount of $10.7 million to cover the security 

deposit under the lease of our headquarters, workers’ compensation insurance program, customs and bank deposits and 
certain value added tax claims in Europe. 

On January 12, 2019 we announced that our Board of Directors authorized a one-year share repurchase program 

of up to $35 million of our common stock. These shares may be purchased in the open market or through privately 
negotiated transactions. We have no obligation to repurchase shares under the authorization, and the timing, actual 
number and value of shares which are repurchased will depend on a number of factors, including the price of our 
common stock, general business and market conditions, and alternative investment opportunities. We may suspend or 
discontinue the repurchase program at any time.

We have no off-balance sheet arrangements at December 31, 2018, exclusive of operating leases. 

We have net operating loss and tax credit carryforwards, the tax effect of which aggregate $67.1 million at 
December 31, 2018. These carryforwards, which expire principally between 2019 and 2038, are available to reduce 
future income tax liabilities in the United States and certain foreign jurisdictions. 

We consider the undistributed earnings of our foreign subsidiaries as of December 31, 2018, to be indefinitely 

reinvested and, accordingly, no U.S. income taxes have been provided thereon. As of December 31, 2018, the amount of 
cash associated with indefinitely reinvested foreign earnings was approximately $4.9 million. We have not, nor do we 
anticipate the need to, repatriate funds to the United States to satisfy domestic liquidity needs arising in the ordinary 
course of business, including liquidity needs associated with our domestic debt service requirements. We anticipate that 
U.S. tax resulting from remitting such earnings will be off-set by net operating loss or credit carryforwards to the extent 
available. In addition, we do not anticipate incurring a foreign withholding tax on remitting such earnings since we do 
not intend to remit the earnings as dividends. 

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

equivalents and borrowing capacity will be sufficient to satisfy our anticipated cash requirements for the short and 
long-term. We currently have no credit facility but management believes we would be able to borrow on reasonable 
terms if needed.

There are no significant related-party transactions that require disclosure in the consolidated financial statements

Recent Accounting Pronouncements 

A discussion of recent accounting pronouncements, the impact of some of which may be material, is included in 
Note 2 to the consolidated financial statements for the year ended December 31, 2018 included in this Annual Report on 
Form 10-K. 

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

Interest Rate Sensitivity 

Our exposure to market risk for changes in interest rates relates primarily to our investment portfolio, which 

consists entirely of cash equivalents at December 31, 2018. The primary objective of our investment activities is to 
preserve principal. This is accomplished by investing in marketable investment grade securities. We do not use derivative 
financial instruments in managing our investment portfolio. 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. 

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 revenue is billed in U.S. dollars and operating expenses are incurred in the local currency. 
During the years ended December 31, 2018 and 2017, approximately 22.5% and 23.5% of our revenue were derived in 
local currencies from foreign operations with this inherent risk. In addition, at both December 31, 2018 and 2017, our 
operations outside of the United States accounted for approximately 12.9% and 14.6% of our total assets, respectively, 
the majority of which was denominated in currencies other than the U.S. dollar. We do not use derivative financial 
instruments in managing our foreign currency exchange risk. 

Item 8.  Financial Statements and Supplementary Data.

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, 2018. 

In making this assessment, management used the criteria set forth in the Committee of Sponsoring Organizations of the 
Treadway Commission (COSO) Internal Control—2013 Integrated Framework. 

Based on this assessment, management has concluded that, as of December 31, 2018, 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 

To the Stockholders and the Board of Directors of Axcelis Technologies, Inc.  

Opinion on Internal Control over Financial Reporting  

We have audited Axcelis Technologies, Inc.’s internal control over financial reporting as of December 31, 2018, 

based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring 
Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Axcelis 
Technologies, Inc. (the Company) maintained, in all material respects, effective internal controls over financial reporting 
as of December 31, 2018, based on the COSO criteria.   

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board 
(United States) (PCAOB), the 2018 consolidated financial statements of the Company and our report dated March 11, 
2019 expressed an unqualified opinion thereon. 

Basis for Opinion  

The Company’s management is responsible for maintaining effective internal control over financial reporting 

and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying 
Management’s 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 are a public accounting firm registered 
with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal 
securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.  

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan 

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

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

Definition and Limitations of Internal Control Over Financial Reporting  

A company’s internal control over financial reporting is a process designed to provide reasonable assurance 

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

Because of its inherent limitations, internal control over financial reporting may not prevent or detect 
misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls 
may become inadequate because of changes in conditions, or that the degree of compliance with the policies or 
procedures may deteriorate.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

To the Stockholders and the Board of Directors of Axcelis Technologies, Inc. 

Opinion on the Financial Statements  

             We have audited the accompanying consolidated balance sheets of Axcelis Technologies, Inc. (the Company) as 
of December 31, 2018 and 2017, the related consolidated statements of operations, comprehensive income, stockholders’ 
equity and cash flows for each of the three years in the period ended December 31, 2018, and the related notes and 
financial statement schedule listed in the Index at Item 15(a), collectively referred to as the “consolidated financial 
statements”. In our opinion, the consolidated financial statements present fairly, in all material respects, the financial 
position of the Company at December 31, 2018 and 2017, and the results of its operations and its cash flows for each of 
the three years in the period ended December 31, 2018, in conformity with U.S. generally accepted accounting 
principles.   

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board 
(United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2018, based on 
criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of 
the Treadway Commission (2013 framework) and our report dated March 11, 2019 expressed an unqualified opinion 
thereon. 

Adoption of New Accounting Standard 

As discussed in Note 2 to the consolidated financial statements, the Company changed its method for 

accounting for revenue in 2018. 

Basis for Opinion 

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

an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with 
the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal 
securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.  

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan 

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

/s/ Ernst & Young LLP 

We have served as the Company’s auditor since 1999.

Axcelis Technologies, Inc. 
Notes to Consolidated Financial Statements 

Note 1. Nature of Business 

Axcelis Technologies, Inc. (“Axcelis” or the “Company”) was incorporated in Delaware in 1995, and is a 

worldwide producer of ion implantation and other processing equipment used in the fabrication of semiconductor chips 
in the United States, Europe and Asia. In addition, we provide extensive aftermarket service and support, including spare 
parts, equipment upgrades, used equipment and maintenance services to the semiconductor industry. 

Note 2. Summary of Significant Accounting Policies 

The accompanying consolidated financial statements reflect the application of certain significant accounting 

policies as described in this note and elsewhere in the footnotes. 

(a)          Basis of Presentation 

The accompanying consolidated financial statements include the consolidated accounts of the Company and its 

wholly-owned, controlled subsidiaries. All intercompany balances and transactions have been eliminated in 
consolidation.  

Events occurring subsequent to December 31, 2018 have been evaluated for potential recognition or disclosure 

in the consolidated financial statements. 

(b)          Use of Estimates 

The preparation of these consolidated financial statements in conformity with accounting principles generally 

accepted in the United States of America requires management to make estimates and assumptions that affect the 
reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the dates of the financial 
statements and the reported amounts of revenue and expenses during the reporting periods. On an ongoing basis, we 
evaluate our estimates and judgments, including those related to revenue recognition, the realizable value of inventories, 
valuing stock-based compensation instruments and reserves relating to tax assets and liabilities. Actual amounts could 
differ from these estimates. Changes in estimates are recorded in the period in which they become known. 

(c)          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, 2018 we had $1.3 million in foreign exchange loss. For the year ended 

December 31, 2017 we had $1.1 million in foreign exchange gains. For the year ended December 31, 2016 we had $0.6 
million in foreign exchange losses.  

(d)          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 funds, U.S Government and Agency Securities 
and deposit accounts. Cash equivalents are carried on the balance sheet at fair market value. 

42 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
(e)          Inventories 

Inventories are carried at lower of cost or net realizable value, determined using the first-in, first-out (“FIFO”) 

method, or market. We periodically review our inventories and make provisions as necessary for estimated obsolescence 
or damaged goods to ensure values approximate lower of cost or net realizable value. 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. 

We record a provision for estimated excess inventory. The provision 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. 

(f)          Property, Plant and Equipment 

Property, plant and equipment are stated at cost, less accumulated depreciation and amortization. 

Depreciation and amortization are recorded using the straight-line method over the estimated useful lives of the 

related assets as follows: 

Asset Classification 

Land and buildings (under lease) 
Machinery and equipment 

    Estimated Useful Life 

Lesser of the lease term or 
estimated useful life of the asset 

     7 to 10 years 

On January 30, 2015, we sold our corporate headquarters facility. As part of this sale, we also entered into a 22-
year lease agreement. We accounted for the sale leaseback transaction as a financing arrangement for financial reporting 
purposes. We retained the historical costs of the property and the related accumulated depreciation on our financial books 
within property, plant and equipment and will continue to depreciate the property for financial reporting purposes over 
the lesser of its remaining useful life or its initial lease term of 22 years.   

Repairs and maintenance costs are expensed as incurred. Expenditures for renewals and betterments are 

capitalized. 

(g)          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. 

We did not have any indicators of impairment during the period ending December 31, 2018. We did not record 

an impairment charge in the years ended December 31, 2018, 2017, or 2016. 

Actual performance could be materially different from our current forecasts, which could impact 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.

 (h)         Concentration of Risk and Off-Balance Sheet Risk 

Financial instruments that potentially subject us to concentrations of credit risk are principally cash equivalents 
and accounts receivable. Our cash equivalents are principally maintained in investment grade money-market funds, U.S. 
Government and Agency Securities and deposit accounts. 

We have no significant off-balance-sheet risk such as currency exchange contracts, option contracts or other 

hedging arrangements. 

Our exposure to market risk for changes in interest rates relates primarily to cash equivalents. The primary 

objective of our investment activities is to preserve principal without significantly increasing risk. This is accomplished 
by investing in marketable investment grade securities. We do not use derivative financial instruments to manage our 
investment portfolio and do not expect operating results or cash flows to be affected to any significant degree by any 
change in market interest rates. 

We perform ongoing credit evaluations of our customers’ financial condition and generally requires no 

collateral to secure accounts receivable. For selected overseas sales, we require customers to obtain letters of credit 
before product is shipped. We maintain an allowance for doubtful accounts based on our assessment of the collectability 
of accounts receivable. We review the allowance for doubtful accounts quarterly. We do not have any off-balance sheet 
credit exposure related to our customers. 

Our customers consist of semiconductor chip manufacturers located throughout the world and net sales to our 

ten largest customers accounted for 76.9%, 73.3% and 70.2% of revenue in 2018, 2017 and 2016, respectively. 

For the year ended December 31, 2018, we had two customers representing 20.1% and 12.1% of total revenue, 

respectively. For the year ended December 31, 2017 we had two customers representing 24.9% and 13.1% of total 
revenue, respectively. For the year ended December 31, 2016, we had one customer representing 17.0% of total revenue.   

As of December 31, 2018, we had two customers account for 21.9% and 11.5% of consolidated accounts 

receivable, respectively. As of December 31, 2017, we had three customers account for 19.8%, 11.8% and 10.6% of 
consolidated accounts receivable, respectively.  

Some of the components and sub-assemblies included in our products are obtained either from a sole source or a 

limited group of suppliers. Disruption to our supply source, resulting either from economic conditions or other factors, 
could affect our ability to deliver products to our customers. 

(i)          Revenue Recognition 

Under Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 

606, Revenue from Contracts with Customers or (“ASC 606”), revenue is recognized when a customer obtains control of 
promised goods or services in an amount that reflects the consideration we expect to receive in exchange for those goods 
or services. We measure revenue based on the consideration specified in the customer arrangement, and revenue is 
recognized when the performance obligations in the customer arrangement are satisfied. A performance obligation is a 
promise in a contract to transfer a distinct product or service to the customer. The transaction price of a contract is 
allocated to each distinct performance obligation based upon the relative standalone selling price for each performance 
obligation and recognized as revenue when or as, the customer receives the benefit of the performance obligation. To 
account for and measure revenue, we apply the following five steps: 

1) 

Identify the contract with the customer 

A contract with a customer exists when (i) we enter into an enforceable contract with a customer that defines 

each party’s rights regarding the goods or services to be transferred and identifies the related payment terms, (ii) the 
contract has commercial substance, and (iii) we determine that collection of substantially all consideration for goods and 
services that are transferred is probable based on the customer’s intent and ability to pay the promised consideration.  

44 

 
 
 
 
 
 
 
 
 
 
 
2) 

Identify the performance obligations in the contract 

Performance obligations promised in a contract are identified based on the goods and services that will be 

transferred to the customer that are both capable of being distinct, whereby the customer can benefit from the good or 
service either on its own or together with other available resources, and are distinct in the context of the contract, 
whereby the transfer of the good or service is separately identifiable from other promises in the contract. To the extent a 
contract includes multiple promised goods and services, we must apply judgment to determine whether promised goods 
and services are capable of being distinct and distinct in the context of the contract. If these criteria are not met, the 
promised goods and services are accounted for as a combined performance obligation. 

Systems sales consist of multiple performance obligations, including the system itself and obligations that are 

not delivered simultaneously with the system. These undelivered obligations 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. 

The aftermarket business includes both products and services type arrangements. Performance obligations in 

these contracts consist of used tools, spare parts, equipment upgrades, maintenance services and customer training.  

Customers who purchase new systems are provided an assurance-type warranty for one year after acceptance of 

the tool. For aftermarket transactions, we provide customers an assurance-type warranty for 90 days. Customers can 
choose to purchase extended warranty terms with enhanced support similar to a service-type warranty ranging from one 
to three years. In accordance with ASC 606, assurance-type warranties are not considered a performance obligation, 
whereas service-type warranties are.   

3)  Determine the transaction price  

The transaction price is determined based on the consideration to which we will be entitled in exchange for 

transferring goods and services to the customer. To the extent the transaction price includes variable consideration, we 
estimate the amount of variable consideration that should be included in the transaction price utilizing either the expected 
value method or the most likely amount method depending on the nature of the variable consideration. Variable 
consideration is included in the transaction price if, in our judgment, it is probable that a significant future reversal of 
cumulative revenue under the contract will not occur. Any estimates, including the effect of the constraint on variable 
consideration, are evaluated at each reporting period for any changes. In applying this guidance, Companies must also 
consider whether any significant financing components exist.  

The transaction price for all transactions is based on the price reflected in the individual customer’s purchase 
order. Variable consideration has not been identified as a significant component of the transaction price for any of our 
transactions.  

For those transactions where all performance obligations will be satisfied within one year or less, we apply the 

practical expedient outlined in ASC 606-10-32-18. This practical expedient allows us not to adjust promised 
consideration for the effects of a significant financing component if we expect at contract inception that the period 
between when we transfer the promised good or service to a customer and when the customer pays for that good or 
service will be one year or less. For those transactions that are expected to be completed after one year, we have assessed 
that there are no significant financing components because any difference between the promised consideration and the 
cash selling price of the good or service is for reasons other than the provision of financing.  

4)  Allocate the transaction price to performance obligations in the contract 

If the contract contains a single performance obligation, the entire transaction price is allocated to the single 

performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction 
price to each performance obligation on a relative standalone selling price basis unless the transaction price is variable 
and meets the criteria to be allocated entirely to a performance obligation or to a distinct service that forms part of a 
single performance obligation.  

Where required, we determine standalone selling price (SSP) for each obligation based on consideration of both 

45 

 
 
 
 
 
market and Company specific factors, including the selling price and profit margin for similar products, the cost to 
produce, and the anticipated margin. 

For those contracts that contain multiple performance obligations (primarily systems sales, as well as some 

aftermarket contracts requiring both time and material inputs), we must determine the SSP. We use a cost plus margin 
approach in determining the SSP for any materials related performance obligations (such as upgrades, spare parts, 
systems). To determine the SSP for labor related performance obligations (such as the labor component of installation), 
we use directly observable inputs based on the standalone sale prices for these services.  

5)  Recognize revenue when or as we have satisfied a performance obligation  

We satisfy performance obligations either over time or at a point in time. Revenue is recognized over time if 
either 1) the customer simultaneously receives and consumes the benefits provided by the entity’s performance, 2) the 
entity’s performance creates or enhances an asset that the customer controls as the asset is created or enhanced, or 3) the 
entity’s performance does not create an asset with an alternative use to the entity and the entity has an enforceable right 
to payment for performance completed to date. If the entity does not satisfy a performance obligation over time, the 
related performance obligation is satisfied at a point in time by transferring the control of a promised good or service to a 
customer. Examples of control are using the asset to produce goods or services, enhance the value of other assets or settle 
liabilities, and holding or selling the asset.  For over time recognition, ASC 606 requires us to select a single revenue 
recognition method for the performance obligation that faithfully depicts our performance in transferring control of the 
goods and services. The guidance allows entities to choose between two methods to measure progress toward complete 
satisfaction of a performance obligation:  

Output methods - recognize revenue on the basis of direct measurements of the value to the customer of the 
goods or services transferred to date relative to the remaining goods or services promised under the contract 
(e.g. surveys of performance completed to date, appraisals of results achieved, milestones reached, time elapsed, 
and units produced or units delivered); and  

Input methods - recognize revenue on the basis of the entity’s efforts or inputs to the satisfaction of a 
performance obligation (e.g., resources consumed, labor hours expended, costs incurred, or time elapsed) 
relative to the total expected inputs to the satisfaction of that performance obligation. 

We have the right to consideration from a customer in an amount that corresponds directly with the value to the 

customer of the entity’s performance completed to date (i.e. certain aftermarket contracts), as such we have elected a 
practical expedient to recognize revenue in the amount to which the entity has a right to invoice for such services. 

Product related revenues (whether for systems or aftermarket business) are recognized at a point in time, when 

they are shipped or delivered, depending on shipping terms.   

For installation services, revenue is recognized at a point in time, once the installation of the tool is complete. 

The nature of the installation services are such that the customer does not simultaneously receive and consume the 
benefits provided by the entity’s performance, nor does performance of installation services create or enhance an asset 
that the customer controls. Installation services do not create an asset with an alternative use to the entity, and the entity 
does not have an enforceable right to payment for performance completed to date.   

Contract liabilities are reflected as deferred revenue on the consolidated balance sheet. Contract liabilities relate 

to payments invoiced or received in advance of completion of performance obligations under a contract. Contract 
liabilities are recognized as revenue upon the fulfillment of performance obligations. 

Service-type warranties for any product are recognized over time, as these represent a stand ready obligation to 

service the product during the warranty period. Progress in the satisfaction of these performance obligations will be 
measured using an input method of time elapsed.  

Maintenance and service contracts are recognized over time.  Progress in the satisfaction of these performance 

46 

 
 
 
 
 
 
 
obligations will be measured using an input method of either time elapsed in the case of fixed period contracts, or labor 
hours expended, in the case of project based contracts. 

(j)          Recognizing Assets related to Recoverable Customer Contract Costs 

We recognize an asset related to incremental costs incurred by us to obtain a contract with a customer if we 

expect to recover those costs. We will recognize an asset from costs incurred to fulfill a contract only if such costs relate 
directly to a contract with an entity that we can specifically identify, the costs incurred will generate or enhance resources 
that will be used in satisfying performance obligations in the future, and the costs are expected to be recovered. Any 
assets recognized related to costs to obtain or fulfill a contract are amortized on a systematic basis that is consistent with 
the transfer to the customer of the goods or services to which the asset relates. 

In substantially all of our business transactions, we incur incremental costs to obtain contracts with customers, 

in the form of sales commissions. We maintain a commission program which awards our employees for System sales, 
aftermarket activity and other individual goals. Under ASC 606, an asset is amortized on a systematic basis that is 
consistent with the transfer to the customer of the goods or services to which the asset relates. However, ASC 606 
provides a practical expedient to allow for the recognition of commission expense when incurred if the amortization 
period of the asset that the entity otherwise would have recognized is one year or less. Based on the nature of our 
commission agreements, all commissions are expensed as incurred based upon the expectation that the amortization 
period would be one year or less.   

(k)          Shipping and Handling Costs 

Shipping and handling costs are included in cost of revenue. 

(l)         Stock-Based Compensation 

We generally recognize compensation expense for all stock-based payments to employees and directors, 
including grants of stock options and restricted stock units, based on the grant-date fair value of those stock-based 
payments. For stock option awards, we use the Black-Scholes option pricing model, adjusted for expected forfeitures. 
Other valuation models may be utilized in the limited circumstances where awards with market-based vesting 
considerations, such as the price of our common stock, or performance based awards, are granted. Stock-based 
compensation expense is recognized ratably over the requisite service period. For each stock option or restricted stock 
unit grant with vesting based on a combination of time, market or performance conditions, where vesting will occur if 
either condition is met, the related compensation costs are recognized over the shorter of the explicit service period or the 
derived service period. 

See Note 13 for additional information relating to stock-based compensation. 

(m)         Income Taxes 

We record 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 basis, and operating loss and tax credit carryforwards. 

Our 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. We establish 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 our provision for income 
taxes, our deferred tax assets and liabilities and any valuation allowance recorded against those net deferred tax assets. 
We evaluate 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. 

47 

 
 
 
 
 
 
 
 
 
 
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. We recognize accrued interest related to unrecognized tax benefits as 
interest expense and penalties within operating expense in the consolidated statements of operations. 

(n)         Computation of Net Income 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. 

The components of net income per share are as follows:

Accounting Standard Codification 606 on Revenue Recognition Adopted January 1, 2018 

Effective January 1, 2018, we adopted FASB ASC Topic 606, Revenue from Contracts with Customers, or ASC 

606. In accordance with ASC 606, we changed certain characteristics of our revenue recognition accounting policy as

described below. On adoption, ASC 606 was applied only to open contracts using the modified retrospective method, 
where the cumulative effect of the initial application is recognized as an adjustment to opening retained earnings at 
January 1, 2018. Therefore, comparative prior periods have not been adjusted and continue to be reported under FASB 
ASC Topic 605, Revenue Recognition, or ASC 605.  

The impact of adoption on our consolidated statement of operations for the twelve months ended December 31, 

2018 and consolidated balance sheet as of December 31, 2018 was as follows (in thousands):

The impact of the adoption of ASC 606 on consolidated statements of comprehensive income and cash flows 

for the twelve months ended December 31, 2018 was not material. 

Upon adoption of ASC 606, we changed our accounting policy for the installation performance obligation 
included in all system sales. Previously under ASC 605, we deferred revenue for the greater of the fair value of the 
installation or the portion of contract consideration for which collection was contingent upon installation completion (the 
“retention”). The concept of contingent consideration is no longer relevant under ASC 606 and therefore we will only 
defer the portion of the transaction price allocated to the installation performance obligation. As a result of this change, 
we recorded a cumulative effect adjustment to increase retained earnings and decrease deferred revenue on January 1, 
2018 by $1.6 million. Since the adoption, all new contracts are accounted for under ASC 606. Our revenue recognition 
policies addressing the nature, amount and timing of revenue and cash flows arising from contracts with customers are 
included in section (i) of Note 2, Summary of Significant Accounting Policies.

Accounting Standard Update 2016-15 on Cash Receipts Adopted January 1, 2018 

In August 2016, the FASB issued ASU No. 2016-15 “Classification of Certain Cash Receipts and Cash

Payments.” The ASU is intended to add or clarify guidance on the classification relating to specific cash flow receipts 
and payments in the statement of cash flows and to eliminate the diversity in practice related to such classifications. The 
guidance in ASU 2016-15 is required for annual reporting periods beginning after December 15, 2017, and is to be 
applied retrospectively for each period presented. Adoption of ASU 2016-15 had no material effect on our consolidated 
financial statements and disclosures. 

iii. 

Accounting Standard Update 2017-07 on Retirement Benefits Adopted January 1, 2018 

In March 2017, the FASB issued ASU No. 2017-07 “Compensation – Retirement Benefits (Topic 715): 

Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.” The ASU is 
intended to improve the presentation of net periodic pension cost and net periodic postretirement benefit cost. The 
amendment applies to all entities offering a defined benefit pension plan, other postretirement benefit plans, or other 
types of benefits accounted for under Topic 715. The amendments in the ASU require an employer to report the service 
cost component in the same line item or items as other compensation costs arising from services rendered by the 
pertinent employees during the period. The other components of net benefit cost are required to be presented in the 
income statement separately from the service cost component and outside a subtotal of income from operations. The 
amendments in this ASU are effective for public business entities for annual periods beginning after December 15, 2017, 
including interim periods within the annual period. The amendments in this ASU should be applied retrospectively for 
the presentation of the service cost component and the other components of net periodic pension cost and net periodic 
postretirement benefit cost in the income statement and prospectively, on and after the effective date, for the 
capitalization of the service cost component of net periodic pension cost and net periodic postretirement benefit in assets. 
Adoption of ASU 2017-07 had no material effect on the consolidated financial statements and disclosures. 

iv. 

Accounting Standard Update 2016-02 on Leases to be Effective January 1, 2019 

In February 2016, the FASB issued ASU No. 2016-02 “Leases.” The ASU requires lessees to recognize the 
rights and obligations created by most leases as assets and liabilities on their balance sheet and continue to recognize 
expenses on their income statement over the lease term. It will also require disclosures designed to give financial 
statement users information on the amount, timing, and uncertainty of cash flows arising from leases. The guidance is 
effective for annual reporting periods beginning after December 15, 2018, and interim periods within those years. Early 
adoption is permitted for all entities. In July 2018, the FASB issued ASU No. 2018-11 “Leases (Topic 842)”, that 
provides targeted improvements relating to the transition method options with which to adopt the new standard. Under 
this additional and optional transition method, an entity initially applies the new lease standard at the adoption date and 
recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. An 
entity that elects this transition method must provide the required Topic 840 disclosures for all periods that continue to be 
in accordance with Topic 840.  

We will elect the package of practical expedients permitted under the transition guidance within the new 
standard, which among other things, allows us to carryforward the historical lease classification. We will make an 
accounting policy election to keep leases with an initial term of 12 months or less off of the balance sheet. We will use 
the transition method allowed under ASU 2018-11. We are currently finalizing our implementation of procedures 
regarding reporting and disclosure controls. We anticipate adopting the new standard on January 1, 2019 using the 
modified retrospective approach under the ASU 2018-11 transition method with the primary effect to be the recognition 
of additional right-of-use assets and corresponding liabilities related to operating leases. We expect to recognize 
approximately $6.1 million of right-of-use assets and related liabilities regarding our operating leases for office space, 
computer and office equipment, as well as vehicles used in our business. We will recognize the lease payments in the 
Consolidated Statement of Operations on a straight-line basis over the respective lease term. The adoption of this 
standard is not expected to have a material impact on our results of operations and cash flows.  

v. 

Accounting Standard Update 2018-13 on Fair Value Measurements to be Effective January 1, 2020 

In August 2018, the FASB issued ASU No. 2018-13 “Fair Value Measurement (Topic 820).” The amendments 
in ASU No. 2018-13 modify the disclosure requirements on fair value measurements in Topic 820, removing disclosure 
requirements for transfers between Level 1 and Level 2 within the fair value hierarchy, as well as modifying the 
disclosure requirement relating to the timing of liquidation for investments calculated on net asset value. The ASU also 

50 

 
 
 
 
 
 
 
requires the disclosure of unrealized gains and losses for the period included in other comprehensive income for Level 3 
instruments. The amendments in this Update are effective for all entities for fiscal years, and interim periods within those 
years, beginning after December 15, 2019. The amendments on changes for unrealized gains and losses should be 
applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. 
Early adoption is permitted. We are currently evaluating the impact of ASU 2018-13 on the consolidated financial 
statements and disclosures. 

Note 3. Correction of an Accounting Error in a Prior Period 

Subsequent to the filing of our 2017 Annual Report on Form 10-K, in April 2018, an error was discovered in the 

consolidated statement of cash flow for the year ended December 31, 2017. The error had no impact upon our 
consolidated statement of operations or consolidated balance sheet.  This error resulted in presenting the provision for 
excess and obsolete inventory as a cash outflow, rather than a cash inflow, with a corresponding and offsetting error in 
the disclosed effect on cash for the change in inventories. The following financial statement line items reported in our 
consolidated statement of cash flow for the year ended December 31, 2017 were affected by the correction of this error:

Note 4. Revenue 

We design, manufacture and service ion implantation and other processing equipment used in the fabrication of 
semiconductor chips and sell our products to leading semiconductor chip manufacturers worldwide. We offer a complete 
line of high energy, high current and medium current implanters for all application requirements. In addition, we provide 
extensive aftermarket lifecycle products and services, including used tools, spare parts, equipment upgrades, 
maintenance service and customer training. Our revenue recognition policies are set forth in Section (i) of Note 2, 
Summary of Significant Accounting Policies.  

(a)  Alternative Operational Revenue Categories used by Management 

To reflect the organization of our business operations, management reviews revenue in two categories: revenue 

from sales of new systems and revenue arising from the sale of used systems, parts and labor to customers who own 
systems, which we refer to as “aftermarket.”  

Below are the revenues by categories used by management for the periods covered in this report:

*The impact upon adoption of ASC 606 was an increase to systems revenue of $1.0 million twelve month 
period ended December 31, 2018. Please refer to Note 2 for additional discussion of ASC 606 adoption impact on 
revenue amounts and comparable revenue figures. The increase in revenue in the twelve month period ended December 
31, 2018, in comparison to the twelve month period ended December 31, 2017, is attributable to an increase in sales of 
our Purion products and aftermarket business.

(b)  Economic Factors Affecting our Revenue: Geographic Breakdown of Revenue 

Global economic conditions have a direct impact on our revenue. We are substantially dependent on sales of our 
products and services to customers outside the United States. Adverse economic conditions, political instability, potential 
adverse tax consequences and volatility in exchange rates pose a risk that our clients may reduce, postpone or cancel 
spending for our products and services, which would impact our revenue.  

Revenue by geographic markets is determined based upon the location to which our products are shipped and 

where our services are performed. Revenue in our principal geographic markets is as follows:  

North America  
Asia Pacific 
Europe

* The impact upon adoption of ASC 606 for the twelve months ended December 31, 2018 was primarily an 

increase in revenue to Asia of $1.3 million, partially offset by a decline to North America of $0.2 million. Please refer to 
Note 2 for additional discussion of ASC 606 adoption impact on revenue amounts and comparable revenue figures.

Contract liabilities are reflected as deferred revenue on the consolidated balance sheet. Contract liabilities relate 

to payments invoiced or received in advance of completion of performance obligations under a contract. Contract 
liabilities are recognized as revenue upon the fulfillment of performance obligations. The increase in contract liabilities 
of $4.4 million from December 31, 2017 to December 31, 2018 is primarily due to the timing of system acceptances, 
offset by the reclassification of $1.6 million relating to our adoption of ASC 606 into retained earnings.

The majority of our system transactions have payment terms that are 90% due upon shipment of the tool and 
10% due upon installation. Aftermarket transaction payment terms are such that payment is due either within 30 or 60 
days of service provided or delivery of parts.  

As of December 31, 2018, we had deferred revenue of $22.6 million. This represents the portion of the 
transaction price for contracts with customers allocated to the performance obligations that remain unsatisfied or partially 
unsatisfied.  Short-term deferred revenue of $19.5 million represents performance obligations that will be satisfied within 
the next 12 months. This amount relates primarily to installation and non-standard warranty performance obligations for 
system sales. Long-term deferred revenue of $3.1 million relates primarily to unsatisfied extended warranty performance 
obligations that we expect to be satisfied within the next 24 months.

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 
collectability 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 allowance may be necessary.

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

value. We establish 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 our products or market conditions. We regularly 
evaluate 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. In 2018, we recorded a 
net decrease of $0.3 million in inventory reserves. As of December 31, 2018 and 2017, inventories are stated net of 
inventory reserves of $13.9 million and $14.2 million respectively. 

During each of the years ended 2018, 2017 and 2016, we recorded charges to cost of sales of $2.2 million, $8.1 

million and $0.8 million to reflect the lower of cost or net realizable value. 

We have inventory on consignment at customer locations as of December 31, 2018 and 2017, of $4.6 million 

and $3.6 million, respectively.

2017 and 2016, respectively. 

Note 10. 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 adjusts the amount as necessary. 

The changes in our product warranty liability are as follows: 

Balance at January 1 (beginning of year) 
Warranties issued during the period 
Settlements made during the period 
Changes in estimate of liability for pre-existing warranties 
during the period

On January 30, 2015, we sold our corporate headquarters facility for the sale price of $48.9 million. As part of 

the sale, we also entered into a 22-year lease agreement with the buyer. The sale leaseback is accounted for as a 
financing arrangement for financial reporting and, as such, we recorded a financing obligation of $47.8 million as of 
December 31, 2018. The associated lease payments include both an interest component and payment of principal, with 
the underlying liability being extinguished at the end of the original lease term. We posted a collateralized security

Note 12. Employee Benefit Plans 

(a)          Defined Contribution Plan 

We maintain the Axcelis Long-Term Investment Plan, a defined contribution plan. Eligible employees may 

contribute up to 35% of their compensation on a before-tax basis subject to Internal Revenue Service (“IRS”) limitations. 
Highly compensated employees may contribute up to 16% of their compensation on a before-tax basis subject to IRS 
limitations. In 2015, we implemented a matching contribution of up to one thousand U.S. dollars on a dollar-for-dollar 
basis on contributions by eligible participants. In 2016, we increased the matching contribution to a maximum of $1,200, 
on the basis of one dollar matched for each two dollars contributed by eligible participants. In 2017, we increased the 
matching contribution to 50% of employees’ pre-tax contributions on the first 6% of eligible compensation contributed to 
the plan. Total related matching contribution expense was $1.6 million, $1.2 million and $0.5 million, for 2018, 2017 and 
2016, respectively. 

(b)          Other Compensation Plans 

We operate in foreign jurisdictions that require lump sum benefits, payable based on statutory regulations, for 

voluntary or involuntary termination. Where required, an annual actuarial valuation of the benefit plans is obtained. 

We have recorded an unfunded liability of $4.3 million and $4.6 million at December 31, 2018 and 2017, 

respectively, for costs associated with these compensation plans in foreign jurisdictions. The following table presents the 
classification of these liabilities in the Consolidated Balance Sheets:

We maintain the Axcelis Technologies, Inc. 2012 Equity Incentive Plan (the “2012 Equity Plan”), which 

became effective on May 2, 2012. Our 2000 Stock Plan (the “2000 Stock Plan”) expired on May 1, 2012 and no new 
grants may be made under that plan after that date. However, awards granted under the 2000 Stock Plan prior to the 
expiration remain outstanding and subject to the terms of the 2000 Stock Plan. 

The 2012 Equity Plan, as amended, reserves 6.5 million shares of common stock, $0.001 par value, for grant 
and permits the issuance of options, stock appreciation rights, restricted stock, restricted stock units, stock equivalents 
and awards of shares of common stock that are not subject to restrictions or forfeiture to selected employees, directors 
and consultants of the Company. The 2012 Equity Plan includes shares specifically approved by the stockholders of the 
Company. Shares that are not issued under an award (because such award expires, is terminated unexercised or is

forfeited) revert back to the Plan. The reserve under the Plan is also increased by expirations and forfeitures of awards 
outstanding under the 2000 Stock Plan as of May 2, 2012. 

The term of stock options granted under these plans is specified in the award agreements. Unless a lesser term is 

otherwise specified by the Compensation Committee of the Company’s Board of Directors, awards under the 2012 
Equity Plan will expire seven years from the date of grant. In general, all awards issued under the 2000 Stock Plan expire 
ten years from the date of grant. Under the terms of these stock plans, the exercise price of a stock option may not be less 
than the fair market value of a share of the Company’s common stock on the date of grant. Under the 2012 Equity Plan, 
fair market value is defined as the last reported sale price of a share of the common stock on a national securities 
exchange as of any applicable date, as long as the Company’s shares are traded on such exchange. 

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 six months and, once 
vested, are not affected by the director’s termination of service to the Company. In limited circumstances, the Company 
may grant stock option awards with market-based vesting conditions, such as the Company’s common stock price, or 
other performance conditions. Termination of service by an employee will cause options to cease vesting as of the date of 
termination, and in most cases, employees will have 90 days after termination to exercise options that were vested as of 
the termination of employment. In general, retiring employees will have one year after termination of employment to 
exercise vested options. The Company settles stock option exercises with newly issued common shares. 

Restricted stock units granted to employees during 2018 had both service-based vesting provisions and 
performance-based vesting provisions. Restricted stock units granted to employees generally vest over a service period of 
four years, while restricted stock units granted to non-employee members of the Company’s Board of Directors generally 
vest over a service period of six months. We have granted restricted stock units to executive officers and other senior 
employees with performance vesting conditions, which may be subject to further service-based vesting terms. Unvested 
restricted stock unit awards expire upon termination of service to the Company. We settle restricted stock units upon 
vesting with newly issued common shares. No restricted stock was granted under either stock plan during the three year 
period ended December 31, 2018.  

As of December 31, 2018, there were 0.6 million shares available for grant under the 2012 Equity Plan. No 

shares are available for grant under the 2000 Stock Plan. 

As of December 31, 2018, there were 2.3 million options outstanding under the 2012 Equity Plan and the 2000 

Stock Plan, collectively, and 0.8 million unvested restricted stock units outstanding under the 2012 Stock Plan. 

(b)          Employee Stock Purchase Plan 

The Employee Stock Purchase Plan (the “Purchase Plan”) provides effectively all of our 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 as elected by the participant, subject to certain caps set forth in the 
Purchase Plan. Employees may purchase the Company’s common stock at 85% of its market price on the day the stock is 
purchased. 

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 relating to the Purchase Plan was approximately $0.2 million for the year ended December 31, 
2018 and approximately $0.1 million for each of the years ended December 31, 2017 and 2016. 

As of December 31, 2018, there were a total of 0.2 million shares reserved for issuance and available for 

purchase under the Purchase Plan. Less than 0.1 million shares were purchased under the Purchase Plan in each of the 
years ended December 31, 2018, 2017 and 2016. The Purchase Plan will expire in June 2020, unless re-approved by the 
Board of Directors, with approval of stockholders within twelve months thereafter.

(c)          Valuation of Stock Options and Restricted Stock Units 

For the purpose of valuing stock options with service conditions, we use 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: 

Weighted-average expected volatility 
Weighted-average expected term 
Risk-free interest rate 
Expected dividend yield 

2018* 
N/A 
N/A 
N/A 
N/A 

Year ended December 31,  

2017* 
N/A

N/A 

2016 
  49.3% — 56.7%  
4.7 years 
  1.1% — 2.0%   
0% 

*No stock option awards were granted in 2018 and 2017.  

Expected volatility—We consider a number of factors when estimating volatility for stock options granted. Our 
method of estimating expected volatility relies on a combination of historical and implied volatility. We believe that this 
blended volatility results in an accurate estimate of the grant-date fair value of employee stock options because it 
appropriately reflects the market’s current expectations of future volatility. 

Expected term—We calculated the weighted average expected term for stock options granted prior to July 1, 

2012, using a forward looking lattice model of the Company’s stock price incorporating a suboptimal exercise factor and 
a projected post-vest forfeiture rate. For stock options granted after July 1, 2012 to employees and to non-employee 
members of the Company’s Board of Directors, we used the simplified method for estimating the expected life of “plain 
vanilla” options because we did not have sufficient exercise history to use a lattice model. We expect that we will use a 
lattice model once sufficient exercise history has been established. A change in the contractual life from 10 years to 
7 years was made to reflect the fact that options granted after May 1, 2012 were granted under the 2012 Equity Incentive 
Plan, which limits option terms to seven years. 

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 we 

do not pay dividends and have no current plans to do so in the future. 

In limited circumstances, we also issue stock option grants with vesting based on market conditions, such as the 

Company’s common stock price, or a combination of time or market or performance conditions. The fair values and 
derived service periods for all grants that have vesting based on market or performance conditions are estimated using 
the Monte Carlo valuation method. For each stock option grant with vesting based on a combination of time and 
performance or market conditions, where vesting will occur if either condition is met, the related compensation costs are 
recognized over the shorter of the explicit service period or the derived service period. 

The fair value of the Company’s restricted stock units is calculated based upon the fair market value of the 

Company’s stock at the date of grant. 

(d)          Summary of Stock-based Compensation Expense 

We use 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. We estimate 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. Based on a historical 

58 

 
 
 
 
 
 
 
 
 
 
 
 
 
    
 
    
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
analysis, a forfeiture rate of 5% per year was applied to stock-based awards, including executive officer awards, for the 
years ended December 31, 2018, 2017 and 2016. 

For the year ended December 31, 2018, we recognized stock-based compensation expense of $7.8 million. 

Stock-based compensation expense was $5.7 million and $5.2 million for the years ended December 31, 2017 and 2016, 
respectively. We present the expenses related to stock-based compensation in the same expense line items as cash 
compensation paid to our employees. For the years ended December 31, 2018, 2017 and 2016, we used restricted stock 
units in our annual equity compensation program.  

The benefit of tax deductions in excess of recognized compensation cost is reported as a financing cash flow, 

rather than as an operating cash flow. Axcelis had tax deductions in excess of recognized compensation cost of $4.1 
million for the year ended December 31, 2018 which resulted in a tax benefit of $0.9 million. Because we did not 
recognize the benefit of tax deductions in excess of recognized compensation cost due to our cumulative net operating 
loss position, this had no impact on our consolidated statement of cash flows as of and for the years ended December 31, 
2018, 2017 and 2016.

(1)   In addition to the vested options, we expect 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. 

The total intrinsic value, which is defined as the difference between the market price at exercise and the price 

paid by the employee to exercise the options, for options exercised during the years ended December 31, 2018, 2017 and 
2016 was $4.1 million, $39.7 million and $2.5 million, respectively. 

The total fair value of stock options vested during the years ended December 31, 2018, 2017 and 2016 was 

$1.9 million, $3.1 million and $3.9 million respectively. The weighted average grant-date fair value of options granted 
for the year ended December 31, 2016 was $5.75. As of December 31, 2018, there was $0.7 million of total 
forfeiture-adjusted unrecognized compensation cost related to non-vested stock options granted under the 2012 Equity 
Incentive Plan and the 2000 Stock Plan. That cost is expected to be recognized over a weighted-average period of 
0.7 years. 

(f)          Restricted Stock Units and Restricted Stock 

Restricted stock units 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 Award Agreement issued under the 2012 Equity Incentive Plan. 
Restricted stock unit awards granted in 2018 included time vested share awards and awards with performance vesting

conditions. No restricted stock was granted, or vested, during the years ended December 31, 2018, 2017 and 2016. The 
fair value of a restricted stock unit and restricted stock award is charged to expense ratably over the applicable service 
period. 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. 

Changes in the Company’s non-vested restricted stock units for the year ended December 31, 2018 is as 

follows:

The weighted average grant-date fair value of restricted stock units granted for the years ended December 31, 

2018, 2017 and 2016 was $22.41, $20.72 and $9.73, respectively. Most restricted stock units provide for net share 
settlement to cover the employee’s personal income tax withholding obligations on vesting of the employee’s restricted 
stock units. Vesting activity above reflects shares vested before net share settlement. As of December 31, 2018, there was 
$11.7 million of total forfeiture-adjusted unrecognized compensation cost related to non-vested restricted stock units 
granted under the 2012 Equity Incentive Plan. That cost is expected to be recognized over a weighted-average period of 
2.7 years. 

Note 14. Stockholders’ Equity 

We may issue up to 75 million shares of common stock without additional shareholder approval. As of 

December 31, 2018 and 2017, there were 32.6 million and 32.0 million outstanding shares of common stock.  

On January 12, 2019 we announced that our Board of Directors authorized a one year share repurchase program 

of up to $35 million of the Company's common stock. These shares may be purchased in the open market or through 
privately negotiated transactions. We have no obligation to repurchase shares under the authorization, and the timing and 
actual number and value of shares which are repurchased will depend on a number of factors, including the price of the 
Company's common stock, general business and market conditions, and alternative investment opportunities. We may 
suspend or discontinue the repurchase program at any time. 

Note 15. Fair Value Measurements 

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an 

exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market 
participants on the measurement date. 

(a)          Fair Value Hierarchy 

The accounting guidance for fair value measurement requires an entity to maximize the use of observable inputs 

and minimize the use of unobservable inputs when measuring fair value. The standard establishes a fair value hierarchy 
based on the level of independent, objective evidence surrounding the inputs used to measure fair value. A financial 
instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the 
fair value measurement. The fair value hierarchy is as follows: 

60 

 
 
 
 
 
 
 
 
 
 
 
     
 
 
 
 
 
 
 
 
 
  
  
  
  
  
  
  
  
 
 
 
 
 
 
 
 
 
 
Level 1—applies to assets or liabilities for which there are quoted prices in active markets for identical 

assets or liabilities. 

Level 2—applies to assets or liabilities for which there are inputs other than quoted prices that are 
observable for the asset or liability, such as quoted prices for similar assets or liabilities in active markets; 
quoted prices for identical assets or liabilities in markets with insufficient volume or infrequent transactions 
(less active markets); or model-derived valuations in which significant inputs are observable or can be derived 
principally from, or corroborated by, observable market data. 

Level 3—applies to assets or liabilities for which there are unobservable inputs to the valuation 

methodology that are significant to the measurement of the fair value of the assets or liabilities. 

(b)          Assets and Liabilities Measured at Fair Value 

Our money market funds and short-term investments are included in cash and cash equivalents in the 

consolidated balance sheets.  

The following table sets forth Company’s assets and liabilities which are measured at fair value by level within 

the fair value hierarchy.

The carrying amounts reflected in the consolidated balance sheets for accounts receivable, prepaid expenses and 

other current and non-current assets, restricted cash, accounts payable and accrued expenses approximate fair value due 
to their short-term maturities. 

Note 16. Commitments and Contingencies 

(a)          Lease Commitments 

We lease manufacturing and office facilities and certain equipment under operating and capital leases that 

expire through 2037. Rental expense was $4.6 million, $3.9 million and $3.8 million under operating leases for the years

We are not presently a party to any litigation that we believe might have a material adverse effect on our 
business operations. We are, from time to time, a party to litigation that arises in the normal course of our business 
operations. 

(e)          Indemnifications 

Our system sales agreements typically include provisions under which we agree to take certain actions, provide 

certain remedies and defend our customers against third-party claims of intellectual property infringement under 
specified conditions and to indemnify customers against any damage and costs awarded in connection with such claims. 
We have not incurred any material costs as a result of such indemnifications and have not accrued any liabilities related 
to such obligations in the accompanying consolidated financial statements.

Changes in tax rates and tax laws are accounted for in the period of enactment. Our deferred tax assets and 

liabilities are measured at the enacted tax rate expected to apply when these temporary differences are expected to be 
realized or settled. On December 22, 2017, the Tax Cuts and Jobs Act (“2017 Tax Act”) was signed into law and has 
resulted in significant changes to the U.S. corporate income tax system. The 2017 Tax Act eliminates the deferral of U.S. 
income tax on the historical un-repatriated earnings by imposing the Transition Toll Tax, which is a one-time mandatory 
deemed repatriation tax on undistributed foreign earnings. The Transition Toll Tax is assessed on the U.S. shareholder's 
share of the foreign corporation's accumulated foreign earnings that have not previously been taxed. Earnings in the form 
of cash and cash equivalents will be taxed at a rate of 15.5% and all other earnings will be taxed at a rate of 8.0%. During 
2018, the provisional amount for the Toll tax was updated from $4.6 million in 2017 to $3.6 million in 2018 due to 
refinement of earnings and profits during 2018. We consider our accounting regarding the Transition Toll Tax to be 
complete. We accrued income tax liabilities of $0.3 million after utilization of foreign tax and research and development 
credits. The Transition Toll Tax will be paid over an eight-year period, starting in 2018, and will not accrue interest. 

The 2017 Tax Act includes a federal statutory rate reduction from 35% to 21%, the elimination or reduction of 

certain domestic deductions and credits and limitations on the deductibility of interest expense and executive 
compensation. The 2017 Tax Act also transitions international taxation from a worldwide system to a modified territorial 
system and includes base erosion prevention measures on non-U.S. earnings, which has the effect of subjecting certain 
earnings of our foreign subsidiaries to U.S. taxation as global intangible low-taxed income (“GILTI”). The tax related to 
GILTI was $0.4 million for the year ended December 31, 2018. We are treating GILTI as a period cost. 

At December 31, 2018, we had $71.9 million of deferred tax assets worldwide relating to net operating loss 

carryforwards, tax credit carryforwards and other temporary differences, which are available to reduce income taxes in 
future years. We have continued to maintain a $6.8 million valuation allowance in the U.S. against certain tax credits and 
state net operating losses due to the uncertainty of their realization based on long-term Company forecasts and the 
expiration dates on these attributes. If future operating results of the U.S. or these foreign jurisdictions significantly 
exceed expectations, it is reasonably possible that there could be a further reduction in the valuation allowance in the 
future. Further reduction of the valuation allowance, in whole or in part, would result in a non-cash income tax benefit 
during the period of reduction.

At December 31, 2018, we have federal and state net operating loss carryforwards of $226.3 million and foreign 

net operating loss carryforwards of $2.5 million expiring principally between 2019 and 2034. 

We have research and development and other tax credit carryforwards of $22.7 million at December 31, 2018 

that can be used to reduce future federal and state income tax liabilities. These tax credit carryforwards expire principally 
between 2019 and 2038.  

We consider the undistributed earnings of our foreign subsidiaries as of December 31, 2018, to be indefinitely 

reinvested and, accordingly, no U.S. income taxes have been provided thereon. As of December 31, 2018, the amount of 
cash associated with indefinitely reinvested foreign earnings was approximately $4.9 million. We have not, nor do we 
anticipate the need to, repatriate funds to the United States to satisfy domestic liquidity needs arising in the ordinary 
course of business, including liquidity needs associated with our domestic debt service requirements. 

We and our subsidiaries file income tax returns in the U.S. federal jurisdiction and various states and foreign 
jurisdictions. We and most foreign subsidiaries are subject to income tax examinations by tax authorities for all years 
dating back to 2011. Our policy is to recognize interest related to unrecognized tax benefits as interest expense and 
penalties as operating expenses. We believe that we have appropriate support for the income tax positions taken and to be 
taken on our tax returns and that our 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, 2018, we had unrecognized tax benefits related to uncertain tax positions of approximately 

$9.1 million, of which approximately $8.4 million reduced the Company’s deferred tax assets and the offsetting 
valuation allowance and $0.7 million was recorded in other long-term liabilities. During the second quarter of 2018, the 
statute of limitations associated with a tax position previously taken by the Company expired. The related tax reserve of 
$0.3 million and accrued interest of $0.2 million that had been recorded were reversed during the twelve months ended 
December 31, 2018. We recognized a benefit of $0.3 million in interest and penalties related to unrecognized tax benefits 
for the year-ended December 31, 2018.  

A reconciliation of the beginning and ending balance of unrecognized tax benefits are as follows:

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
