     PART I

     ITEM 1. BUSINESS

     GENERAL

     Advanced Energy is a leading supplier of power conversion and control 
systems incorporated in plasma-based thin film production equipment. The 
Company's systems are key elements of semiconductor, data storage, flat panel 
display, and a range of other industrial manufacturing equipment that 
utilizes gaseous plasmas to deposit or etch thin film layers on materials or 
substrates such as silicon, glass and metals. The effectiveness of 
plasma-based production processes depends in large part on the quality of the 
electrical power used to ignite and manipulate the plasma. The Company's 
power conversion and control systems refine, modify and control the raw power 
from a utility and produce power which is uniform, predictable and precisely 
repeatable to permit the production of identical films of unvarying thickness 
on a mass scale. The Company's systems are used in an array of thin film 
processes such as physical vapor deposition, etch, chemical vapor deposition, 
plasma enhanced chemical vapor deposition and ion implantation, as well as a 
broad range of thin film applications such as the production of 
semiconductors, magnetic hard disks, CD-ROMs, audio and video discs, thin 
film heads, liquid crystal displays and optical, glass and automobile 
coatings. The Company's customers include Applied Materials, Lam Research, 
Balzers/Leybold, Materials Research, Multi-Arc and Ulvac.

     In recent years, significant technological advances in thin film processes
have enabled the manipulation of materials on the atomic and molecular level.
Manufacturers can now both deposit and etch layers of materials that are less
than one hundredth of a micron in thickness. By using modern thin film
production processes, manufacturers are better able to control and alter the
electrical, magnetic, optical and mechanical characteristics of materials. Thin
film processes have been employed most extensively in the semiconductor
industry, where multiple thin film layers of insulating or conductive material
are deposited on a wafer or substrate. These processes are now used in a growing
range of diverse industries. Thin film production was initially accomplished
using either liquid chemical or thermal processes. Plasma-based process
technology was developed to address the limitations of wet chemistry and thermal
technologies in certain applications requiring thinner, more precise film, and
to enable new applications.

     The Company has achieved its market leadership position by providing 
systems which convert externally supplied power, operate over a wide range of 
power levels, control utility instabilities such as brownouts and surges 
created by raw utility power sources, control intense localized electrical 
discharges known as arcs and control system instabilities which arise from 
the use of exotic gases and inherently unstable electrode arrangements. All 
of the Company's products employ sophisticated switchmode technology that 
affords plasma-based systems a greater ability to prevent arcs, which can 
slow down the throughput of a plasma process and may even destroy the 
substrate or the 


                                      4

power conversion and control system. The Company believes the combination of 
its in-depth knowledge of plasma physics, its unique approach to product 
customization and its reusable engineering product design methodology have 
enabled it to develop the widest range of power conversion and control 
systems in the industry.

     Since inception, the Company has sold over  58,000 power conversion and 
control systems. Approximately 60% of the Company's sales in 1995 and 61% in 
1996 were to the semiconductor equipment industry. Advanced Energy sells its 
systems primarily through direct sales personnel to customers in the United 
States, Japan and Europe. The Company also sells through distributors in 
Japan, France, Italy, Israel, Korea, and Taiwan. International sales 
represented  29% and  24% of the Company's sales in 1995  and 1996, 
respectively.

DEVELOPMENT OF COMPANY BUSINESS

     Advanced Energy was incorporated in Colorado in 1981 and reincorporated in
Delaware in September 1995. Advanced Energy filed with the Securities and
Exchange Commission (the "Commission") a registration statement on Form S-1
pursuant to the Securities Exchange Act of 1934, as amended, with respect to
Advanced Energy's initial public offering of its common stock, $0.001 par value
("Common Stock").  The registration statement was declared effective by the
Commission in November 1995.  As used in this Form 10-K, references to "Advanced
Energy" refer to Advanced Energy Industries, Inc. and references to the
"Company" refer to Advanced Energy and its consolidated subsidiaries. The
Company's principal executive offices are located at 1625 Sharp Point Drive,
Fort Collins, Colorado 80525, and its telephone number is (970) 221-4670.

PRODUCTS

     The Company's use of switchmode power conversion and control technology 
has enabled it to develop a line of products which has permitted the 
development of new plasma processing applications. In 1982, the Company 
introduced its first low frequency switchmode power conversion and control 
system specifically designed for use in plasma processes. In 1983, the 
Company introduced its first DC system designed for use in PVD sputtering 
applications. This DC based system is a compact, cost-effective power 
solution, which greatly reduced stored energy, a major limitation in the use 
of PVD systems. In the early 1990's the Company introduced the first fully 
switchmode radio frequency (RF) power conversion and control systems for use 
in semiconductor etch applications. This product achieved significant design 
wins because of its smaller size and precise control attributes. The Company 
has recently introduced a family of accessories which provide major 
improvements in arc prevention and suppression. The Company is currently 
extending the power range of its systems to much higher power levels to 
enable it to supply products for emerging industrial applications. The 
Company's 


                                      5

products currently range in price from $2,880 to $80,000, with an average price
of approximately $10,000.

     DIRECT CURRENT PRODUCTS

     THE MDX SERIES.  The Company's MDX series of products was introduced in 
1983. These products are most commonly used as DC power supplies for PVD 
sputtering where precise control, superior arc prevention and suppression and 
low stored energy characteristics are required. They are also used as bias 
supplies for RF sputtering, tool coating and some etching systems. The MDX 
series consists of six different product lines that provide a range of power 
levels from 500 W to 120 kW. The Company's second generation product, the MDX 
II, was introduced in 1991 to support higher power levels and to meet strict 
European regulatory requirements. A lower cost model in the MDX series, the 
MDX-L, was introduced in 1992.

     THE PINNACLE SERIES.  The Pinnacle series, introduced in 1995, is the 
most recent product line in the MDX series. Pinnacle was developed primarily 
for use in DC PVD sputtering processes and provides substantial improvements 
in arc prevention, arc suppression capability, reduced size, higher precision 
and expanded control capability.


                                      7

<PAGE>

     SPARC-LE ACCESSORIES.  The Company's SPARC-LE line of DC accessories, 
introduced in 1993, is designed both to reduce the number of arcs that occur 
in plasma-based processes and to reduce the arc energy if arcs do occur. The 
SPARC-LE accessories are especially effective in applications involving the 
deposition of insulative materials where the reaction between the plasma and 
target is likely to produce more severe arc conditions. The SPARC-LE 
accessories are most commonly used with the MDX product lines. The SPARC-LE 
arc prevention and suppression technology has been incorporated directly into 
the Pinnacle systems.

     LOW AND MID-FREQUENCY PRODUCTS

     THE PE AND PD SERIES.  The PE low frequency power systems were 
introduced in 1982. The PE series systems are air cooled and primarily 
intended for use in certain PVD, CVD and industrial surface modification 
applications, including dual cathode sputtering and printed circuit board 
de-smearing. The PE series systems range in frequency from 25kHz to 100kHz. 
The low frequency PE systems and the PD series of mid-frequency power 
conversion and control systems, introduced in 1990, represented significant 
technological advancements by applying switchmode techniques to higher 
frequencies. The water-cooled PD systems are used primarily in semiconductor 
etch and CVD applications. The PD series range in frequency from 275kHz to 
400kHz. Both the PE and PD series systems have single-stage power generation, 
and include systems that incorporate pulsed power technology.

     RADIO FREQUENCY PRODUCTS

     THE RF SERIES.  The RFX system is a 13.56MHz, 600W, air-cooled platform 
introduced in 1985. This system is used primarily in research and development 
applications. The RFG and RFXII, introduced in 1991 and 1992, respectively, 
are water-cooled power conversion and control systems utilizing a new 
hybrid-based switchmode technology. The RFG and RFXII systems operate at 
frequencies ranging from 4MHz to 13.56MHz. These systems were the first 
entirely switchmode-based RF designs. The RF systems are most commonly used 
in semiconductor processes, including RF sputtering, plasma 
etching/deposition, and reactive ion etching applications. The RFXII is a 
compact system which incorporates new impedance matching technology. This 
technology eliminates certain previously required motors, gear trains, 
variable capacitors and inductors and servomechanism circuitry, which results 
in cost savings and improvements in reliability.

     THE ID SERIES.  The ID power conversion and control systems, introduced 
in 1981, were the first products designed by the Company. These systems were 
specifically designed to power broad beam ion-sources. ID series systems are 
composed of a coordinated set of multiple special purpose power supplies that 
are used for ion-beam deposition and sputtering, ion implantation and 
ion-beam etching and milling.

     THE AZX SERIES.  The AZX series tuners are RF matching networks designed 
as accessories to match the complex electrical characteristics of a plasma to 
the requirements of the Company's RF series of power conversion and control 
systems. AZX tuners, introduced in 1989, are also sold separately for 
incorporation into other vendor's power conversion and control systems. The 
AZX tuners typically operate at a 13.56MHz frequency range. The need for 
these tuner products is reduced with the advent of the Matchless technology 
designed into the RFXII system.

     THE RFZ IMPEDANCE PROBE.  The RF impedance probe, introduced in 1993, is 
used for measuring the RF properties of a plasma. The sensing technology 
incorporated in the RF impedance probe allows accurate, real-time measurement 
of power, voltage, current and impedance levels under actual powered process 
conditions.

including flat panel display, data storage and various industrial 
applications. The following is a discussion of the major markets for the 
Company's systems:

     SEMICONDUCTOR MANUFACTURING EQUIPMENT MARKET.  The Company's products 
are sold primarily to semiconductor equipment manufacturers for incorporation 
into equipment used to make integrated circuits. The Company's products are 
currently employed in a variety of applications, including deposition, etch, 
ion implantation and megasonic cleaning. The precision control over plasma 
processes afforded by the use of the Company's power conversion and control 
systems allows its customers to manufacture semiconductor fabrication systems 
that produce integrated circuits with reduction feature size and increased 
speed and performance. The Company anticipates that the semiconductor 
industry will continue to be a substantial part of its business for the 
foreseeable future.

     FLAT PANEL DISPLAY MANUFACTURING EQUIPMENT MARKET.  The Company also 
sells its systems to manufacturers of flat panel displays (FPDs) and flat 
panel projection devices (FPPs), both of which have fabrication processes 
similar to those employed in manufacturing integrated circuits. FPDs produce 
bright, sharp, large, color-rich images on flat, lightweight screens, such as 
portable computer monitors. Currently, there are three major types of FPDs: 
liquid crystal displays, field emitter displays and gas plasma displays. Two 
types of FPP, another emerging display technology, are currently in 
production: liquid crystal projection and digital micro-mirror displays. The 
Company sells its products to all three of the active FPD markets, as well as 
to each of the FPP markets.

     DATA STORAGE MANUFACTURING EQUIPMENT MARKETS.  The Company's products 
are sold both to data storage equipment manufacturers and to data storage 
device manufacturers for use in producing a variety of products, including 
compact discs, computer hard disks (both media and thin film heads), CD-ROMs 
and digital video discs. These products use a PVD sputtering process to 
produce optical and magnetic thin film layers, as well as a protective wear 
layer. In this market the trend towards higher recording densities is driving 
the demand for increasingly dense, thinner and more precise films. The use of 
equipment incorporating magnetic media to store analog and digital data 
continues to expand with the growth of the laptop, desktop, and workstation 
computer markets.

     INDUSTRIAL MARKETS.  The Company sells its products to both OEMs and 
producers of end products in a variety of industrial markets. Thin films for 
optical purposes are used in the manufacture of many industrial products, 
including solar panels, architectural glass, eyeglasses, lens coatings, 
bar-code readers and front surface mirrors. Thin films of diamond coatings 
and other materials are now being applied to products in plasma-based 
processes to strengthen and harden surfaces on such diverse products as 
tools, automotive parts and hip joint replacements. A variety of industrial 
packaging applications, such as decorative wrapping and food packaging, are 
also enabled by thin film processes utilizing the Company's products. The 
advanced thin film production processes allow precise control of various 
optical and physical properties, including color, transparency and electrical 
and thermal conductivity. The improved adhesion and high film quality 
resulting from plasma processing makes it the preferred method of applying 
the thin films. Many of these industrial applications require power levels 
substantially greater than those used in the Company's other markets.

     CUSTOMERS

     The Company has sold its systems worldwide to more than 100 OEMs and 
directly to more than 500 end-user customers. Since inception, the Company 
has sold more than 58,000 power conversion and control systems. The Company's 
largest customers are involved principally in the semiconductor market. The 
Company also has significant customers in the data storage, flat panel 
display and industrial markets. Sales to Applied Materials and Lam Research 
in 1994, 1995 and 1996 accounted in the aggregate for approximately 38%, 41% 
and 47% of total sales, respectively. The Company expects that sales of its 
products to Applied Materials and Lam Research will continue to account for a 
high percentage of its sales in the foreseeable future. Representative 
customers of the Company include:

               Applied Materials              Lam Research
               Balzers/Leybold                Materials Research
               CVC Products                   Motorola

MARKETING, SALES AND SERVICE

     The Company sells its systems primarily through direct sales personnel to
customers in the United States, Japan and Europe. The Company's sales personnel
are located at the Company's headquarters in Fort Collins, Colorado, and in
regional sales offices in Milpitas, California; Concord, Massachusetts; and
Austin, Texas. To serve customers in Asia and Europe, the Company has offices in
Tokyo, Japan; Bicester, United Kingdom; and Filderstadt, Germany; which have
primary responsibility for sales and service in their respective markets. The
Company also sells to customers in Japan through Landmark Technology Corporation
and has distributors and sales representatives in France, Italy, Israel, Korea
and Taiwan.

     Sales outside the United States represented approximately 32%, 29% and 
24% of the Company's total sales during 1994, 1995 and 1996, respectively. 
The Company expects sales outside the United States to continue to represent 
a significant portion of future sales. Although the Company has not 
experienced any significant difficulties in connection with its international 
sales, such sales are subject to certain risks, including exposure to 
currency fluctuations, the imposition of governmental controls, political and 
economic instability, trade restrictions, changes in tariffs and taxes, and 
longer payment cycles typically associated with international sales. The 
future performance of the Company will depend, in part, upon its ability to 
compete successfully in Japan, one of the largest markets for semiconductor 
fabrication equipment and flat panel display 


                                     11

<PAGE>

equipment, and a major market for data storage and other industrial equipment 
utilizing the Company's systems. The Japanese market has historically been 
difficult for non-Japanese companies to penetrate. Although the Company and a 
number of its significant non-Japanese customers have begun to establish 
operations in Japan, there can be no assurance that the Company or its 
customers will be able to maintain or improve their competitive positions in 
Japan.

     The Company believes that customer service and technical support are 
important competitive factors and are essential to building and maintaining 
close, long-term relationships with its customers. The Company maintains 
customer service offices in Fort Collins, Colorado; Milpitas, California; 
Tokyo, Japan; Seoul, South Korea; and Filderstadt, Germany.

     The Company offers warranty coverage for its systems for periods ranging 
from 12 to 24 months after shipment against defects in design, materials and 
workmanship.

BACKLOG

     A substantial and increasing portion of the Company's shipments are made 
on a "just-in-time" basis, which requires the shipment of systems by the 
Company within a few days or hours after an order is received. The Company 
schedules production for "just-in-time" customers based on forecasts 
provided by such customers. Due to the short time between the receipt of 
orders from such "just-in-time" customers and shipments, the Company operates 
with a level of backlog which is not at any point in time sufficient to meet 
the Company's revenue expectations for a particular quarter. In addition, 
orders from the Company's other customers are subject to cancellation or 
delay by the customer without penalty. Due to these factors, the Company does 
not believe that backlog is a meaningful or accurate indicator of its future 
sales and performance.

MANUFACTURING

     The Company's manufacturing facility is located in Fort Collins, 
Colorado. The Company's manufacturing activities consist of the assembly and 
testing of components and subassemblies which are then integrated into final 
products. Once final testing of all electrical and electro-mechanical 
subassemblies is completed, the final product is tested in a burn-in process 
to identify product failures. The Company purchases a wide range of 
electronic, mechanical, and electrical components, some of which are designed 
to the Company's specifications. The Company does outsource some of its 
subassembly work.

     The Company relies on sole and limited source suppliers for certain 
parts and subassemblies. This reliance creates a potential inability to 
obtain an adequate supply of required components, and reduced control over 
pricing and time of delivery of components. An inability to obtain adequate 
deliveries or other circumstances that would 


                                     12

<PAGE>

require the Company to seek alternative sources of supply or to manufacture 
such components or subassemblies internally, either of which might require 
the Company to redesign its systems to accommodate the different components 
or subassemblies, could prevent the Company from shipping its systems to its 
customers on a timely basis. The Company believes that alternative sources 
could be obtained and qualified, if necessary, for sole and limited source 
parts. However, if the Company were forced to seek alternative sources of 
supply or to manufacture such components or subassemblies internally, it may 
be required to redesign its systems, which could prevent the Company from 
shipping its systems to its customers on a timely basis.

INTELLECTUAL PROPERTY

     The Company has a policy of seeking patents on inventions governing new 
products or technologies as part of its ongoing research, development, and 
manufacturing activities. The Company holds ten United States patents 
covering various aspects of its products, and has applied for patents in 
Europe and Japan. The Company believes the duration of its patents generally 
exceeds the life cycles of the technologies disclosed and claimed therein. No 
assurance can be given that the Company's patents will be sufficiently broad 
to protect the Company's technology, nor that any existing or future patents 
will not be challenged, invalidated or circumvented, or that the rights 
granted thereunder will provide meaningful competitive advantages to the 
Company. Any of such events could have a material adverse effect on the 
Company's business, financial condition and results of operations.

     Although the Company is not aware of any infringement by its products of 
any patents or proprietary rights of others, there can be no assurance that 
such infringements do not exist or will not occur in the future. Litigation 
may be necessary in the future to enforce patents issued to the Company, to 
protect trade secrets or know-how owned by the Company, to defend the Company 
against claimed infringement of the rights of others or to determine the 
scope and validity of the proprietary rights of others. Any such litigation 
could result in substantial cost and diversion of effort by the Company, 
which could have a material adverse effect on the Company's business, 
financial condition and results of operations. Moreover, adverse 
determinations in such litigation could result in the Company's loss of 
proprietary rights, subject the Company to significant liabilities to third 
parties, require the Company to seek licenses from third parties or prevent 
the Company from manufacturing or selling its products, any of which could 
have a material adverse effect on the Company's business, financial condition 
and results of operations.

COMPETITION

     The markets the Company serves are highly competitive and characterized 
by rapidly evolving technology. Significant competitive factors in the 
Company's markets include product performance, price, quality and reliability 
and level of customer service and 


                                     13

<PAGE>

support. The Company believes that it currently competes effectively with 
respect to these factors, although there can be no assurance that the Company 
will be able to compete effectively in the future.

     The markets in which the Company competes have seen an increase in 
global competition, especially from Japanese-based and European-based 
equipment vendors. The Company has several foreign and domestic competitors 
for each of the DC, low-frequency and mid-frequency AC, and radio frequency 
AC lines of products. Some of these competitors are larger and have greater 
resources than the Company. The Company's ability to continue to compete 
successfully in these markets will depend upon its ability to introduce 
product enhancements and new products on a timely basis. The Company's 
primary competitors are ENI, a subsidiary of Astec (BSR) PLC, Huttinger, 
Shindingen, Kyosan, RF Power Products, Comdel and Daihen. The Company's 
competitors in each product area are expected to continue to improve the 
design and performance of their systems and to introduce new systems with 
competitive performance characteristics. To remain competitive, the Company 
believes it will be required to maintain a high level of investment in 
research and development and sales and marketing. No assurance can be given 
that the Company will continue to be competitive in the future.

INDUSTRY SEGMENTS

     The Company operates entirely within one industry sector.

RESEARCH AND DEVELOPMENT

     The market for power conversion and control systems and related 
accessories is characterized by rapid technological changes. The Company 
believes that continued and timely development of new products and 
enhancements to existing products to support OEM requirements is necessary 
for the Company to maintain a competitive position in the markets the Company 
serves. Accordingly, the Company devotes a significant portion of its 
personnel and financial resources to research and development projects and 
seeks to maintain close relationships with its customers and other industry 
leaders to remain responsive to their product requirements.

     Research and development expenses were approximately $5.8 million, $10.5 
million and $13.8  million in fiscal 1994, 1995 and 1996, respectively. These 
amounts represented 11.3%, 11.1% and 13.9% of total sales for those periods. 
From 1994 to 1996, the Company introduced more than sixty-five new products. 
The Company believes that continued research and development investment is 
essential to ongoing development of new products and does not expect any 
significant decline in spending as a percentage of sales.

NUMBER OF EMPLOYEES

    At December 31, 1996, the Company had a total of  630 employees, of whom 
600 are full-time continuous employees. None of the Company's employees is 
represented by a union, and the Company has never experienced a work 
stoppage. The Company utilizes temporary employees as a means to provide 
additional staff while reviewing the performance of the temporary employee. 
The Company considers its employee relations to be good.


EFFECTS OF ENVIRONMENTAL LAWS

    The Company is subject to federal, state and local environmental laws and 
regulations.  The Company is in compliance with all such laws and regulations.


CAUTIONARY STATEMENTS - RISK FACTORS

    In the interest of providing the Company's shareholders and potential 
investors with certain Company information, including management's assessment 
of the Company's future potential, certain statements set forth herein 
contain or are based on projections of revenue, income, earnings per share 
and other financial items or relate to management's future plans and 
objectives or to the Company's future economic performance. Such statements 
are "forward-looking statements" within the meaning of Section 27A(i) of the 
Securities Act of 1933, as amended, and in Section 21E(i) of the Securities 
Exchange Act of 1934, as amended.

    Although any forward-looking statements contained herein or otherwise 
expressed by or on behalf of the Company are to the knowledge and in the 
judgment of the officers and directors of the Company, expected to prove true 
and to come to pass, management is not able to predict the future with 
absolute certainty. Accordingly, shareholders and potential investors are 
hereby cautioned that certain events or circumstances could cause actual 
results to differ materially from those projected or predicted herein. In 
addition, the forward-looking statements herein are based on management's 
knowledge and judgment as of the date hereof, and the Company does not 
intend to update any forward-looking statements to reflect events occurring 
or circumstances existing hereafter.

    In particular, the Company believes that the following factors could 
impact forward-looking statements made herein or in future written or oral 
releases and by hindsight, prove such statements to be overly optimistic and 
unachievable.


VOLATILITY OF THE SEMICONDUCTOR AND SEMICONDUCTOR EQUIPMENT INDUSTRIES

    Approximately 60% of the Company's sales in 1995 and 61% in 1996 were 
made to OEMs and other customers in the semiconductor equipment industry. The 
Company expects that its business will continue to depend in significant part 
on the semiconductor 



                                      15

<PAGE>
                                       
and semiconductor equipment industries for the foreseeable future. The 
Company's business depends in large part upon capital expenditures by 
manufacturers of semiconductor devices, which in turn depends upon the 
current and anticipated market demand for semiconductor devices and products 
utilizing such devices. The semiconductor industry historically has been 
volatile and has experienced periods of oversupply, resulting in 
significantly reduced demand for semiconductor fabrication equipment. There 
can be no assurance that the growth in the semiconductor and semiconductor 
equipment industries, or the resulting growth in the Company's business, can 
be sustained or that there will not be a downturn or slowdown in any of such 
markets which could have a material adverse effect on the Company's business, 
financial condition and results of operations.


CUSTOMER CONCENTRATION

    Sales to Applied Materials and Lam Research, the two leading domestic 
manufacturers of semiconductor fabrication equipment, together accounted for 
approximately 41% and 47% of the Company's revenues during 1995 and 1996, 
respectively. The Company expects that sales of its systems to Applied 
Materials and Lam Research will continue to account for a high percentage of 
its sales in the foreseeable future. The loss of any of its major customers, 
particularly Applied Materials or Lam Research, or a reduction in orders from 
any of such customers, including reductions caused by changes in a customer's 
competitive position or economic conditions in the industries in which the 
Company's customers compete, could have a material effect on the Company's 
business, financial condition and results of operations.  


DEPENDENCE ON DESIGN WINS

    The Company believes that design wins are critical to retaining existing 
customers and to obtaining new customers. Generally an equipment manufacturer 
selects a power conversion and control system for each of its systems and 
products. Because power conversion and control systems vary in 
characteristics such as power, dimensions and modes of interfacing with the 
customer's equipment, once a power conversion and control system is selected 
for use in a particular system or product, it is unlikely that it will be 
displaced during the life of that system or product. As a result, the 
Company's failure to achieve design wins for semiconductor fabrication and 
other equipment could have a material and prolonged adverse effect on the 
Company's sales and growth.


RAPID TECHNOLOGICAL CHANGE AND DEPENDENCE ON NEW SYSTEM INTRODUCTION

    The market for power conversion and control systems is characterized by 
ongoing technological developments and changing customer requirements. The 
markets in which the Company's customers compete are also characterized by 
continually evolving technology. The Company's success depends upon its 
ability to continue to improve existing systems and to develop and introduce 
new systems that keep pace with technological advances and adapt to support 
its customers' changing needs. There can be no assurance that the Company 
will continue to be able to improve its existing systems or 



                                      16

<PAGE>
                                       
develop new systems that will adequately address the changing needs of its 
customers and the marketplace. Even if the Company is able to develop 
improved or new systems, there can be no assurance that such systems will be 
cost-effective or introduced in a timely manner. Development and introduction 
of new systems may involve significant costs that are difficult to forecast. 
Failure of the Company to develop or introduce improved systems and new 
systems in a timely manner could have a material adverse effect on the 
Company's business, financial condition and results of operations, as well as 
on its customer relationships.


COMPETITION

    The Company faces substantial competition, primarily from established 
companies, some of which have greater financial, marketing and technical 
resources than the Company. The Company expects its competitors to continue 
to develop new products aimed at applications currently served by the 
Company, to continue to improve the design and performance of their systems, 
and to introduce new systems with competitive performance characteristics. To 
remain competitive, the Company believes it will be required to maintain a 
high level of investment in research and development and sales and marketing. 
There can be no assurance that the Company will have sufficient resources to 
continue to make such investments or that the Company will be able to make 
the technological advances necessary to maintain its competitive position. In 
addition, new products developed by competitors could make pricing more 
competitive, which may necessitate significant price reductions by the 
Company or result in lost orders, either of which could have a material 
adverse effect on the Company's business, financial condition and results of 
operations.


MANAGEMENT OF GROWTH

    The Company is experiencing a period of rapid growth and expansion, which 
has placed, and is expected to continue to place, significant demands on the 
Company's resources. The management of such growth will require the Company 
to continue to improve and expand its management, operational and financial 
systems, procedures and controls, including accounting and other internal 
management systems, quality control, delivery and service capabilities. To 
accommodate its recent growth, the Company expects to implement in 1997 a new 
integrated information management system that will incorporate substantially 
all of the Company's internal financial and business systems, procedures and 
controls. Any failure to manage growth effectively, including delays or 
difficulties implementing the new systems, procedures and controls in a 
timely manner and without disruption of the Company's operations, could have 
a material adverse effect on the Company's business, financial condition and 
results of operations.

ITEM 7.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND 
          RESULTS OF OPERATIONS

OVERVIEW

     The Company designs, manufactures, markets and supports power conversion 
and control systems used in industrial processes. The Company's systems are 
key elements in products that utilize gaseous plasmas to deposit or etch thin 
film layers on materials or substrates such as silicon, glass and metals. The 
Company commenced operations in 1981 and has been profitable each year since 
its inception. The Company markets and sells its systems primarily to 
original equipment manufacturers (OEMs) of semiconductor, flat panel display, 
data storage and other industrial thin film manufacturing equipment. A 
substantial and increasing proportion of the Company's sales are made on a 
"just-in-time" basis in which the shipment of systems occurs within a few 
days or hours after an order is received. The Company recognizes revenues, 
which are derived from the sales of power conversion and control systems, 
upon shipment of its systems.

     The semiconductor equipment industry accounted for approximately 60% of 
the Company's sales in 1995 and 61% in 1996. The Company has benefited from 
strong growth in the semiconductor industry in recent years until the 
industry growth slowed in mid-1996. The two largest customers of the Company 
are also the largest domestic semiconductor equipment manufacturers. The 
Company has also experienced growth in sales to the other industries it 
serves during the last three years, with the exception of a decline in sales 
to the flat panel display industry in 1996, primarily in Japan. The future 
success of the Company depends on continued growth of the semiconductor 
equipment industry, data storage industry, flat panel display industry, and 
other industries requiring thin film manufacturing processes. To date, the 
Company has been successful in achieving a number of "design wins" which have 
resulted in the Company obtaining new customers and solidifying relationships 
with its existing customers. The Company believes that its ability to 
continue to achieve design wins with existing and new customers will be 
critical to its future success.

     In response to the high rate of growth in 1994 and 1995 and anticipated 
growth during 1996, the Company made substantial investments in 
infrastructure such as information technology, facilities, sales and support 
worldwide in 1996, which caused operating expenses to increase. This, 
combined with the slower growth in the semiconductor industry, resulted in 
reduced operating margins in 1996. Margins are not expected to improve until 
the semiconductor equipment industry rebounds and returns to growth more in 
line with historical experience.

     During the third quarter, the Company announced cost containment 
measures in response to recent declines in orders to the semiconductor 
capital equipment market. As part of these measures, the Company reduced 
headcount by 7%, reduced leased facilities 



                                     22

<PAGE>

by 7%, initiated a 10% decrease in senior management salaries and reevaluated 
inventories for excess and obsolete parts. These efforts resulted in 
additional charges of $350,000 related to severance pay, charges associated 
with subleasing facilities and an increased provision for excess inventories.

RESULTS OF OPERATIONS

     The following table sets forth certain statement of operations data of the
Company expressed as a percentage of sales:

                                          ------     ------     ------

     SALES

     Sales were $51.9 million, $94.7 million and $98.9 million in 1994, 1995 
and 1996, respectively, representing an increase of 82% from 1994 to 1995 and 
4% from 1995 to 1996. The Company's sales growth during all periods presented 
has resulted from the increased unit sales of the Company's systems. A 
significant part of this growth during 1996 is attributable to increased 
sales to domestic customers and to customers in Europe, offset by a 46% 
decrease in Japan sales when compared to 1995. In 1995 the Company sold 
subsystems in Japan to replace subsystems originally provided by competitors.
That retrofit program was completed in 1995. A substantial portion of the 
Company's sales growth since 1994 is attributable to higher system sales to 
the Company's two largest customers, both of whom are primarily semiconductor 
equipment OEMs.

     Sales to international customers, primarily in Japan, Asia and Europe, 
were approximately $16.7 million, $27.3 million, and $24.0 million in 1994, 
1995 and 1996, respectively. These amounts represented 32%, 29% and 24% of 
sales for those periods. During these periods, sales in Japan were primarily 
to flat panel display and data storage equipment manufacturers and sales in 
Europe were primarily to data storage equipment manufacturers.


                                     23

<PAGE>

     GROSS MARGIN

     The Company's gross margins during the periods presented have varied in 
the range of 37.2% to 49.8%. Gross margin of 49.8% in 1994 and 47.9% in 1995 
decreased to 37.2% in 1996. Major factors causing the decrease in gross 
margin from 1995 to 1996 were generally higher material costs and other costs 
associated with continued outsourcing efforts in the first half of 1996, and 
underabsorption of manufacturing overhead due to lower sales in the second 
half of 1996. Sales for the first six months of 1996 were $57.0 million 
versus sales of $43.0 million in the comparable period in 1995, an increase 
of 33%, while sales in the last six months of 1996 were $41.9 million versus 
sales of $51.7 million for the comparable period in 1995, a decrease of 19%. 
Additionally, gross margin was negatively impacted throughout 1996 by a shift 
in product mix toward products on which material costs increased as a 
percentage of sales and by increased customer service costs, which increased 
as a percentage of sales, as a result of the lower sales base.

     During the periods presented, the average selling price per unit has 
remained relatively constant. Historically, price competition has not had a 
material effect on margins. However, competitive pressures may produce a 
decline in average selling prices for certain products. Any material decline 
in average selling prices not offset by reduced costs could result in a 
material decline in the Company's gross margins.

     The Company provides warranty coverage for its systems ranging from 12 
to 24 months. The Company estimates the anticipated costs of repairing its 
systems under such warranties based on the historical average costs of the 
repairs. To date, the Company has not experienced significant warranty costs 
in excess of its recorded reserves.

    RESEARCH AND DEVELOPMENT

     The Company's research and development costs are associated with 
researching new technologies, developing new products and improving existing 
product designs. Research and development expenses were $5.8 million, $10.5 
million and $13.8 million for 1994, 1995 and 1996, respectively, representing 
an increase of 81% from 1994 to 1995 and 31% from 1995 to 1996. As a 
percentage of sales, research and development expenses decreased from 11.3% 
in 1994 to 11.1% in 1995 and increased to 13.9% in 1996. The increase in 
expenses from 1995 to 1996 are primarily associated with increases in payroll 
costs and outside service costs incurred to support new product development 
and standards compliance certification.

     The Company believes that continued research and development investment 
is essential to ongoing development of new products and does not expect any 
significant decline in spending as a percentage of sales. Since inception, 
all research and development costs have been internally funded and expensed.


                                     24

<PAGE>

     SALES AND MARKETING

     Sales and marketing expenses support domestic and international sales 
and marketing activities which include personnel, trade shows, advertising, 
and other marketing activities. Sales and marketing expenses were $4.7 
million, $6.2 million and $8.6 million for 1994, 1995 and 1996, respectively. 
This represented a 32% increase from 1994 to 1995 and a 39% increase from 
1995 to 1996. The increases are attributable to increases in payroll, 
promotional materials, advertising, commissions and travel costs associated 
with expansion to support the increase in sales volume. As a percentage of 
sales, these expenses decreased from 9.0% in 1994 to 6.5% in 1995 and 
increased to 8.7% in 1996. The increase of sales and marketing as a 
percentage of sales during 1996 was attributed to a lower than anticipated 
sales base achieved during the period.

     The Company is reorganizing its sales and marketing team to better 
address the specific needs of its customers. To accomplish this, the Company 
hired a vice president of sales, marketing and customer support, and opened a 
new support office in South Korea.  As a result, sales and marketing expenses 
may continue to increase as a percentage of sales in future periods.

     GENERAL AND ADMINISTRATIVE

     General and administrative expenses support the worldwide financial, 
administrative, information systems and human resources functions of the 
Company. General and administrative expenses were $5.3 million, $7.2 million 
and $6.3 million which represented 10.2%, 7.6% and 6.3% of sales for 1994, 
1995 and 1996, respectively. The overall decrease as a percentage of sales 
from 1994 to 1996 is attributable to the Company's effort to maintain a level 
of general and administrative costs that do not increase at the same rate as 
sales.  Most of the decreases in these costs were recognized in payroll, 
recruitment fees, and travel. 

     The Company is currently implementing information management system 
software which will replace existing systems to support its growth. The 
Company expects that significant charges related to training and 
implementation of the new software will occur during 1997.

     OTHER INCOME (EXPENSE)

     Other income consists primarily of foreign exchange gains and losses and 
other miscellaneous income and expense items. Approximately 60% of the 
Company's foreign sales are denominated in local currencies. The Company 
recognized a foreign exchange gain of $0.4 million in 1994, primarily due to 
increases in the values of both the German Deutsch Mark and the Japanese Yen. 
An increase in the value of the Deutsch Mark of 7% and a decrease in the 
value of the Yen of 4% resulted in essentially no foreign exchange gain or 
loss in 1995. During 1996 the Company recorded a net foreign 


                                     25

<PAGE>

exchange loss of $0.4 million primarily as a result of a 12% decrease in the 
value of the Yen. During the second half of 1996 the Company entered into 
various forward foreign exchange contracts to mitigate the effect of 
depreciation in the Japanese Yen. The Company continues to evaluate various 
policies to minimize the effect of currency fluctuations.

     Interest expense consists principally of borrowings under the Company's 
bank credit and capital lease facilities and was approximately $0.6 million, 
$0.6 million and $0.2 million for the years 1994, 1995 and 1996, 
respectively. Interest expense decreased from 1995 to 1996 primarily as a 
result of repayments of equipment loans and less borrowing due to the 
availability of working capital provided from the proceeds of the Company's 
initial public offering in November 1995.

     Interest income was approximately $0.1 million, $0.1 million and $0.5 
million for the years 1994, 1995 and 1996, respectively. The increase in 1996 
was due primarily to earnings on investments made from the proceeds of the 
initial public offering in November 1995.

     PROVISION FOR INCOME TAXES

     The income tax provision of $7.8 million in 1995 represented a 37.0% 
effective tax rate. The income tax provision of $3.2 million for 1996 
represented an effective rate of 38.1%. The increase in the Company's tax 
rate from 1995 to 1996 is primarily attributed to a higher effective state 
tax rate resulting from a larger proportion of the Company's sales being 
shipped to higher tax rate jurisdictions, particularly California.  Changes 
in the relative earnings of the Company and its foreign subsidiaries affect 
the Company's consolidated effective tax rate. To the extent that a larger 
percentage of taxable earnings are derived from the Company's foreign 
subsidiaries whose tax rates are higher than domestic tax rates, the Company 
could experience a higher consolidated effective tax rate.

QUARTERLY RESULTS OF OPERATIONS

     The following table presents unaudited quarterly results in dollars and 
as a percentage of sales for the eight quarters ended December 31, 1996. The

     The Company has experienced and expects to continue to experience 
significant fluctuations in its quarterly operating results. The Company's 
expense levels are based, in part, on expectations of future revenues. If 
revenue levels in a particular quarter do not meet expectations, operating 
results may be adversely affected. A variety of factors have an influence on 
the level of the Company's revenues in a particular quarter. These factors 
include general economic conditions, specific economic conditions in the 
industries the Company serves, the timing of the receipt of orders from major 
customers, customer cancellations or delay of shipments, specific feature 
requests by customers, production delays or manufacturing inefficiencies, 
exchange rate fluctuations, management decisions to commence or discontinue 
product lines, the Company's ability to design, introduce and manufacture new 
products on a cost effective and timely basis, the introduction of new 
products by the Company or its competitors, the timing of research and 
development expenditures, and expenses related to acquisitions, strategic 
alliances, and the further development of marketing and service capabilities.



                                     27

     A substantial portion of the Company's shipments are made on a 
"just-in-time" basis in which shipment of systems occurs within a few days or 
hours after an order is received. The Company's backlog is not meaningful 
because of the importance of "just-in-time" shipments.  The Company is 
dependent on obtaining orders for shipment in a particular quarter to achieve 
its revenue objectives for that quarter. Accordingly, it is difficult for the 
Company to predict accurately the timing and level of sales in a particular 
quarter. Due to its "just-in-time" program, the Company anticipates quarterly 
fluctuations in sales will continue to occur.
  
     The Company's quarterly operating results in 1995 and 1996 reflect 
primarily the changing demand for the Company's products during this period, 
principally from manufacturers of semiconductor equipment, and the Company's 
ability to quickly adjust its manufacturing capacity to meet this demand. 
Total sales for the Company increased sequentially from the first quarter of 
1995 through the second quarter of 1996, representing increased demands from 
semiconductor equipment companies. Demand from the semiconductor equipment 
companies, reflecting an overall industry slowdown, dropped significantly in 
the third and fourth quarters of 1996, and demand from the data storage 
market dropped in the fourth quarter of 1996. Segments of the data storage 
industry are cyclical as new manufacturing lines are installed. Both 
slowdowns negatively impacted the revenues of the Company in the second half 
of 1996. Additionally, sales to the flat panel display industry, primarily in 
Japan, were significantly lower throughout 1996 from their 1995 level.

     The Company's gross margin fluctuated significantly on a quarterly basis 
in 1995 and 1996, primarily reflecting utilization of manufacturing capacity. 
Average selling prices remained relatively constant throughout the periods 
presented. The Company's gross margin of 46.3% in the first quarter of 1995 
was attributable to increased hiring of manufacturing personnel in 
anticipation of additional manufacturing capacity becoming available in 1995, 
and to costs associated with outsourcing of subassemblies to further increase 
manufacturing capacity. In the second and third quarters of 1995, the 
Company's gross margin improved to 51.7% and 50.2%, respectively, as the 
Company utilized its additional manufacturing capacity. In the fourth quarter 
of 1995, the gross margin decreased substantially to 43.3%. This resulted 
from increased costs associated with small quantity purchases for parts 
required for a design change required by the Company's customers selling to 
European users; an increase in personnel to support anticipated demand; 
increased costs for outsourced subassemblies; an increase in the 
manufacturing organizations' portion of facilities and information systems; 
and increased costs associated with the expansion of the customer service 
organization. The decrease of gross margin to 37.3% in the first quarter of 
1996 was primarily attributable to higher costs associated with outsourcing 
assemblies, changes in product mix, and costs associated with expanding into 
additional manufacturing facilities. The increase in gross margin to 42.3% in 
the second quarter of 1996 resulted from price reductions achieved through 
negotiations with the Company's supplier base, a reduction in consigned labor 
outsourcing, lower pricing as a result of purchasing negotiations, and a 
decision to produce high labor content printed circuit boards in-house. 
Additionally, gross margin 

                                       28

<PAGE>

was positively impacted by higher revenues than in the first quarter which 
resulted in more favorable absorption of manufacturing overhead. The 
reduction in gross margin to 30.5% in the third quarter of 1996 was primarily 
the result of underabsorbed fixed manufacturing costs from reduced revenue, 
as revenues in the third quarter of 1996 were $8.2 million lower than in the 
second quarter of 1996, and from higher fixed overhead expenses from expanded 
physical capacity. Additionally, gross margin was negatively impacted by a 
shift in product mix toward products on which material costs as a percentage 
of sales were higher than the previous quarter.  Increased customer service 
costs, as a percentage of sales also contributed to the lower gross margin.  
The improvement of gross margin to 36.9% in the fourth quarter of 1996 was 
attributable to a favorable product mix, decreased direct material costs and 
decreased customer service costs, each of which decreased as a percentage of 
sales, and favorable adjustments resulting from a review of inventory 
reserves for excess, obsolete, and revaluation.  

     The Company's operating expenses increased on a quarterly basis 
throughout 1995 and through the first half of 1996. Since the fourth quarter 
of 1995, operating expenses have included additional legal and administrative 
expenses as a result of being a publicly held company. Additionally, the 
Company has expensed costs incurred for consultants used in the 
implementation of a new information management system software. The Company 
expects expenses related to the implementation of the software to continue 
through 1997 as additional phases are implemented, including integration of 
the information systems of the Company's international subsidiaries. 
Decreases in the second half of 1996 reflect a companywide restructuring and 
the implementation of cost containment measures in the third quarter.  As a 
percentage of sales, operating expenses have declined during periods of rapid 
sales growth, when sales increased at a rate faster than the Company's 
ability to add personnel and facilities to support the growth, and increased 
during periods of flat or decreased sales, when the Company infrastructure is 
retained to support anticipated future growth. During the four quarters of 
1995 and the first two quarters of 1996, during periods of growth, operating 
expenses varied between 23% and 28% of sales. In contrast, operating expenses 
as a percentage of sales were 30% and 33%, respectively, for the last two 
quarters of 1996, when sales were lower than in the previous five quarters.

     Other income (expense) consists primarily of interest income and expense 
and foreign currency gain and loss. Net foreign exchange losses of 
approximately $0.5 million in the last half of 1995 offset the foreign 
exchange gains recognized in the previous two quarters. The net foreign 
exchange loss of $0.4 million in 1996 was recognized during the first and 
fourth quarters of 1996, with essentially no gain or loss in the second and 
third quarter. The Company's provision for income taxes has remained 
relatively stable in 1995 and 1996.

LIQUIDITY AND CAPITAL RESOURCES

     Since its inception, the Company has financed its operations, acquired 
equipment and met its working capital requirements through borrowings under 
its revolving line of 


                                       29

<PAGE>

credit, long-term loans secured by property and equipment and cash flow from 
operations, and, from November 1995, proceeds from its initial public 
offering.

     Cash provided by operations totaled $3.7 million in 1995, and $3.3 
million in 1996. In 1995, substantial increases in inventory and accounts 
receivable were more than offset by net income, depreciation and 
amortization, and increases in accounts payable, accrued liabilities and 
income taxes payable. Major factors contributing to cash provided by 
operations in 1996 were net income, depreciation and amortization and 
decreases in inventory, partially offset by increases in accounts receivable 
and decreases in accounts payable. The Company's accounts receivable 
increased from $15.2 million at December 31, 1995 to $16.1 million at 
December 31, 1996, reflecting the Company's increased sales during this 
period. Inventory decreased from $16.1 million to $14.0 million during the 
same period, reflecting the Company's emphasis on improving inventory 
management and additions to certain reserves for potentially excess and 
obsolete inventory.  The Company expects future receivable and inventory 
balances to fluctuate with net sales. The Company provides "just-in-time" 
deliveries to certain of its customers and may be required to maintain 
substantial levels of inventory to satisfy its customers' delivery 
requirements.

     Investing activities, consisting primarily of equipment acquisitions, 
used cash of $3.8 million and $5.1 million in 1995 and 1996, respectively. 
Financing activities in 1995, consisting primarily of net proceeds raised of 
$21.2 million from the initial public offering, offset by note and loan 
repayments, provided cash of $13.9 million in 1995. In 1996, financing 
activities consisted primarily of net proceeds of notes payable to finance 
equipment of $1.6 million, offset by repayments of notes payable and capital 
lease obligations and used cash of $0.3 million. Long-term loans secured by 
property and equipment were $1.6 million in 1995 and $1.5 million in 1996.

     The Company plans to spend approximately $3.0 million through 1997 for 
the acquisition of equipment and integrated information management system 
software, leasehold improvements and furnishings.

     As of December 31, 1996, the Company had working capital of $35.2 
million. The Company's principal sources of liquidity consisted of $11.2 
million of cash and cash equivalents, $10.0 million available under a $10.0 
million revolving line of credit that bears interest at prime rate (8.25% at 
January 31, 1997) or LIBOR plus 250 basis points. The Company has the option 
to convert up to $3.0 million of its revolving line of credit to a 36-month 
term loan that would bear interest at prime plus 0.50%. Covenants under the 
new line of credit include a minimum ratio of quick assets to current 
liabilities of 1.75; a minimum debt service ratio of 2.0; a ratio of debt to 
net worth not to exceed 1.0; a minimum tangible net worth of $38 million; and 
profitability on a quarterly basis with an allowance for one quarterly loss 
up to $0.5 million. In addition, payment of dividends will be prohibited 
without the prior written consent of the bank.


                                       30

<PAGE>

     The Company entered into an agreement effective October 31, 1996, that 
will provide the Company with a $2.5 million line of credit to purchase 
equipment, of which $1.5 million was advanced to refinance previous equipment 
loans. At December 31, 1996, $1.5 million was outstanding under the term 
loan, which bears interest at prime rate plus 0.25% and is due November 5, 
1999.

     The Company believes that its cash and cash equivalents, cash flow from 
operations, and available borrowings will be sufficient to meet the Company's 
working capital needs through at least the end of 1997. After that time, the 
Company may require additional equity or debt financing to address its 
working capital, capital equipment, or expansion needs. There can be no 
assurance that additional funding will be available when required or that it 
will be available on terms acceptable to the Company.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS




To the Stockholders and Board of Directors of
Advanced Energy Industries, Inc.:


     We have audited the accompanying consolidated balance sheets of Advanced 
Energy Industries, Inc. (a Delaware corporation) and subsidiaries as of 
December 31, 1996 and 1995, and the related consolidated statements of 
income, stockholders' equity, and cash flows for each of the three years in 
the period ended December 31, 1996. These consolidated financial statements 
and the schedule referred to below are the responsibility of the Company's 
management. Our responsibility is to express an opinion on these consolidated 
financial statements and schedule based on our audits.

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

     In our opinion, the consolidated financial statements referred to above 
present fairly, in all material respects, the financial position of Advanced 
Energy Industries, Inc. and subsidiaries as of December 31, 1996 and 1995, 
and the results of their operations and their cash flows for each of the 
three years in the period ended December 31, 1996, in conformity with 
generally accepted accounting principles.

     Our audit was made for the purpose of forming an opinion on the basic 
financial statements taken as a whole. The schedule listed in the index of 
the consolidated financial statements is presented for purposes of complying 
with the Securities and Exchange Commission's rules and is not part of the 
basic financial statements. This schedule has been subjected to the auditing 
procedures applied in our audit of the basic financial statements and, in our 
opinion, is fairly stated in all material respects in relation to the basic 
financial statements taken as a whole.



Denver, Colorado                                       ARTHUR ANDERSEN LLP

                  ADVANCED ENERGY INDUSTRIES, INC. AND SUBSIDIARIES

                      NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1) COMPANY OPERATIONS

  Advanced Energy Industries, Inc. (the "Company") was incorporated in Colorado
in 1981 and reincorporated in Delaware in 1995. The Company is primarily engaged
in the development and production of power conversion and control systems which
are used by manufacturers of semiconductors and in industrial thin film
manufacturing processes. The Company owns 100% of each of the following
subsidiaries: Advanced Energy Japan, K.K. ("AE-Japan"), Advanced Energy, GmbH
("AE-Germany") and Advanced Energy U.K. Limited ("AE-UK"). Effective January 1,
1994, the Company converted its tax status from being an S corporation to a C
corporation, and acquired the remaining minority interest in each of these
subsidiaries. Additionally, the Company formed Advanced Energy Industries, FSC
("AE-FSC") in 1994.

  In September 1995, the Company reincorporated in Delaware with an authorized
capitalization of 30,000,000 shares of common stock, $0.001 par value. Also in
September 1995, the Company approved a three for one share common stock split.
All share and per share data have been retroactively adjusted in the
accompanying consolidated financial statements for the effect of the stock
split. Additionally, the Company also authorized 1,000,000 shares of $0.001 par
value preferred stock.

  The Company continues to be subject to certain risks similar to other
companies in its industry. These risks include the volatility of the
semiconductor industry, customer concentration within the industry,
technological changes, dependence on the Japanese market, foreign currency risk
and competition. A significant change in any of these risk factors could have a
material impact on the Company's business.

(2) SIGNIFICANT ACCOUNTING POLICIES

  BASIS OF PRESENTATION -- The consolidated financial statements include the
accounts of the Company and its subsidiaries. All significant intercompany
accounts and transactions have been eliminated in consolidation.

  CASH AND CASH EQUIVALENTS -- For cash flow purposes, the Company considers all
cash and investments with an original maturity of 90 days or less to be cash and
cash equivalents.

  INVENTORIES -- Inventories include costs of materials, direct labor and
manufacturing overhead. Inventories are valued at the lower of cost or market,
computed on a first-in, first-out basis.

  DEMONSTRATION AND CUSTOMER SERVICE EQUIPMENT -- Demonstration and customer
service equipment are manufactured products utilized for sales demonstration and
evaluation purposes. The Company also utilizes this equipment in its customer
service function as replacement and loaner equipment to existing customers. All
equipment is held for sale.

  The Company depreciates the equipment based on its estimated useful life in
the sales and customer service functions. The depreciation is computed based
upon a 3-year life.

  PROPERTY AND EQUIPMENT -- Property and equipment is stated at cost. Additions,
improvements, and major renewals are capitalized. Maintenance, repairs, and
minor renewals are expensed as incurred.

                                     39
<PAGE>

  Depreciation is provided using straight-line and accelerated methods over
three to ten years for machinery and equipment. Amortization of leasehold
improvements and leased equipment is provided using the straight-line method
over the life of the lease term or the life of the assets, whichever is shorter.

  CONCENTRATIONS OF CREDIT RISK -- The Company's revenues generally are
concentrated among a small number of customers, the majority of which are in the
semiconductor industry. The Company establishes an allowance for doubtful
accounts based upon factors surrounding the credit risk of specific customers,
historical trends and other information.

  WARRANTY POLICY -- The Company estimates the anticipated costs of repairing
products under warranty based on the historical average cost of the repairs. The
Company offers warranty coverage for its systems for periods ranging from 12 to
24 months after shipment.

  CUMULATIVE TRANSLATION ADJUSTMENT -- The functional currency for the Company's
foreign operations is the applicable local currency.

  The Company records a cumulative translation adjustment from translation of
the financial statements of AE-Japan, AE-Germany and AE-UK. This equity account
includes the results of translating all balance sheet assets and liabilities at
current exchange rates as of the balance sheet date, and the statements of
operations at the average exchange rates during the respective year.

  The Company recognizes gain or loss on foreign currency transactions which are
not considered to be of a long-term investment nature. The Company recognized a
(loss) gain on foreign currency transactions of $(351,000), $(7,000) and
$389,000 for the years ended December 31, 1996, 1995 and 1994, respectively.

  REVENUE RECOGNITION -- The Company recognizes revenue when products are
shipped.

  INCOME TAXES -- The Company accounts for income taxes in accordance with
Statement of Financial Accounting Standards ("SFAS") No. 109, "Accounting for
Income Taxes."  In accordance with SFAS No. 109, deferred tax assets and
liabilities are recognized for temporary differences between the tax basis and
financial reporting basis of assets and liabilities, computed at current tax
rates.

  NET INCOME PER COMMON AND COMMON EQUIVALENT SHARE -- Net income per share is
computed based on net income attributable to common stock and the weighted
average number of common and common equivalent shares outstanding during each of
the periods since the Company became a C corporation.

  All share and income per share data have been adjusted for all periods to
reflect the three for one split of common shares approved by the Company's
stockholders in September 1995 (Note 1).

  ESTIMATES AND ASSUMPTIONS -- The preparation of the Company's consolidated
financial statements in conformity with generally accepted accounting principles
requires the Company's management to make estimates and assumptions that affect
the amounts reported and disclosed in the consolidated financial statements and
accompanying notes.  Actual results could differ from those estimates.
  
  ACCOUNTING PRONOUNCEMENT -- In March 1995, the Financial Accounting Standards
Board ("FASB") issued SFAS No. 121, "Accounting for the Impairment of Long-Lived
Assets and for Long-Lived Assets to be Disposed Of." SFAS No. 121 requires that
long-lived assets and certain identifiable intangibles to be held and used by an
entity be reviewed for impairment whenever events or changes in circumstances
indicate that the carrying amount of an asset may not be recoverable. The
adoption of SFAS No. 121 in 1996 did not have a significant impact on the
Company's consolidated financial condition and results of operations.

(13) RELATED PARTY TRANSACTIONS

     During 1994, a limited liability partnership consisting of certain 
officers of the Company and other individuals entered into an agreement to 
purchase an office and manufacturing facility. The partnership remodeled the 
office and manufacturing facility and leased the facility to the Company 
under an operating lease. During 1994, the Company provided "bridge" 
financing in the amount of $3,000,000 to the partnership to purchase and 
remodel the building. The Company moved into this facility during 1994. The 
Company recognized $86,000 of interest income related to this transaction 
during 1994. The partnership repaid the bridge loan in the third quarter 1994 
when it obtained permanent financing for the facility. This lease expires in 
2009 with a monthly payment of approximately $39,000. In September 1995, the 
Company entered into a new lease agreement with this partnership for a 
building being constructed adjacent to the Company's executive offices. The 
lease relating to this facility expires in February 2011 with monthly rent 
expense of approximately $46,000.

     The Company also leases other office and production space from another 
limited liability partnership consisting of certain officers of the Company 
and other individuals. The lease relating to this space expires in 2002 with 
a monthly payment of approximately $23,000.

     Approximately $1,364,000, $800,000 and $600,000 was charged to rent 
expense attributable to these leases for the years ended December 31, 1996, 
1995 and 1994, respectively.

     The Company leases, for business purposes, a condominium owned by a 
partnership of certain stockholders. The Company paid the partnership $36,000 
for each of the years ended December 31, 1996, 1995 and 1994, relating to 
this lease.

and 1994, is approximately $394,000, $953,000 and $500,000, respectively, due 
from an entity that is controlled by the president of AE-Japan.  This entity 
also accounted for approximately 3%, 3% and 4% of consolidated sales during 
1996, 1995 and 1994, respectively.

     On June 29, 1995, certain stockholders of the Company exercised options 
to purchase shares of the Company's common stock for an aggregate exercise 
price of $1,083,000. In exchange for the stock the Company received notes 
receivable in the amount of the exercise price. These notes receivable bear 
interest at 6.83% which is payable annually and the principal balance is due 
in June 2000.  As of December 31, 1996, the Company has approximately 
$110,000 of accrued interest income related to these notes included in 
receivables from related parties.

(15) STOCK PLANS

     EMPLOYEE STOCK OPTION PLAN -- During 1993, the Company adopted an 
Employee Stock Option Plan (the "Employee Option Plan") which was amended and 
restated in January and September 1995. The Employee Option Plan allows 
issuance of incentive stock options, nonstatutory options, and stock purchase 
rights. The exercise price of incentive stock options shall not be less than 
100% of the stock's fair market value on the date of grant. The exercise 
price of nonstatutory stock options shall not be less than 50% of the stock's 
fair market value on the date of grant. Options issued in 1996, 1995 and 1994 
were issued at 100% of fair market value, as determined by the Company, with 
typical vesting of one-third at the end of one year, and quarterly thereafter 
until fully vested after three years. Under the Employee Option Plan, the 
Company has the discretion to accelerate the vesting period. The options are 
exercisable for ten years from the date of grant. The Company has reserved 
3,500,000 shares of common stock for the issuance of stock under the Employee 
Option Plan which terminates in June 2003.

     In connection with the grant of certain stock options on June 30, 1995, 
the Company recorded $142,000 of deferred compensation for the difference 
between the deemed fair value for accounting purposes and the option price as 
determined by the Company at the date of grant. This amount is presented as a 
reduction of stockholders' equity and will be amortized over the 3 year 
vesting period of the related stock options.

     In addition, the Company offered to employees the right to purchase 
11,000 warrants for approximately $0.02 each in fiscal 1994. Each warrant 
permitted employees to purchase one share of common stock at fair market 
value, as determined by the Company, at the time the warrant was granted. The 
warrants were exercised during 1994. There are no warrants outstanding as of 
December 31, 1996 and 1995.

     EMPLOYEE STOCK PURCHASE PLAN -- In September 1995, stockholders approved 
an Employee Stock Purchase Plan (the "Stock Purchase Plan") covering an 
aggregate of 200,000 shares of common stock. Employees are eligible to 
participate in the Stock Purchase Plan if employed by the Company for at 
least 20 hours per week during at least five months per calendar year. 
Participating employees may have up to 15% (subject to a 5% limitation set by 
the Company's board of directors for fiscal 1996) of their earnings 



                                      46

<PAGE>

or a maximum of $1,250 per six month period withheld pursuant to the Stock 
Purchase Plan. Common stock purchased under the Stock Purchase Plan will be 
equal to 85% of the lower of the fair market value on the commencement date 
of each offering period or the relevant purchase date. During 1996, employees 
purchased an aggregate of 11,572 shares under the Stock Purchase Plan and the 
Company recognized approximately $11,000 in compensation expense.

     OUTSIDE DIRECTOR STOCK OPTION PLAN -- In September 1995, the Company 
adopted the 1995 Non-Employee Directors Stock Option Plan (the "Directors 
Plan") covering 50,000 shares of common stock. The Directors Plan provides 
for automatic grants of nonstatutory stock options to directors of the 
Company who are not employees of the Company ("Outside Directors"). Pursuant 
to the Directors Plan, upon becoming a director of the Company, each Outside 
Director will be granted an option to purchase 7,500 shares of common stock. 
Such options will be immediately exercisable as to 2,500 shares of common 
stock, and will vest as to 2,500 shares of common stock on each of the second 
and third anniversaries of the grant date. On each anniversary of the date on 
which a person became an Outside Director, an option for an additional 2,500 
shares is granted. Such additional options vest on the third anniversary of 
the date of grant. Options will expire ten years after the grant date, and 
the exercise price of the options will be equal to the fair market value of 
the common stock on the grant date. The Directors Plan terminates September 
2005.

     The following summarizes the activity relating to options and warrants for
the years ended December 31, 1996, 1995 and 1994:

     Statement of Financial Accounting Standards No. 123, "Accounting for 
Stock-Based Compensation" ("SFAS No. 123"), defines a fair value based method 
of accounting for employee stock options or similar equity instruments.  
However, SFAS No. 123 allows the continued measurement of compensation cost 
for such plans using the intrinsic value based method prescribed by APB 
Opinion No. 25, "Accounting for Stock Issued to Employees" ("APB No. 25"), 
provided that pro forma disclosures are made of net income or loss and net 
income or loss per share, assuming the fair value based method of SFAS No. 
123 had been applied. The Company has elected to account for stock-based 
compensation plans under APB No. 25, under which no compensation expense is 
recognized.

     For SFAS No. 123 purposes, the fair value of each option grant is 
estimated on the date of grant using the Black-Scholes option pricing model 
with the following weighted-average assumptions:

                                                  1996        1995
                                                 -------     -------

               Risk-free interest rates            6.57%       6.16%
               Expected dividend yield rates       0.00%       0.00%
               Expected lives                    4 years     4 years
               Expected volatility               110.16%      22.57%


     The total fair value of options granted was computed to be approximately 
$1,317,000 and $420,000 for the years ended December 31, 1996 and 1995, 
respectively.  These amounts are amortized ratably over the vesting period of 
the options.  Cumulative compensation cost recognized in pro forma net income 
or loss with respect to options that are forfeited prior to vesting is 
adjusted as a reduction of pro forma compensation expense in the period of 
forfeiture.  Pro forma stock-based compensation, net of the effect of 
forfeitures and tax, was approximately $47,000 and $19,000 for 1996 and 1995, 
respectively.
  
     Had compensation cost for these plans been determined consistent with 
SFAS No 123, the Company's net income would have been reduced to the 
following pro forma amounts:

                                       1996             1995
                                      ------          -------
                                      (In thousands, except
                                          per share data)
               Net Income:
                    As reported       $5,144          $13,281
                    Pro forma          5,097           13,262

               Earnings Per Share:
                    As reported       $ 0.24          $  0.69
                    Pro forma           0.24             0.69


     Because the SFAS No. 123 method of accounting has not been applied to 
options granted prior to January 1, 1995, the resulting pro forma 
compensation cost may not be representative of that to be expected in future 
years.

     The following table summarizes information about the stock options 
outstanding at December 31, 1996:
