                                   ANADIGICS

    We are a leading supplier of radio frequency/microwave integrated circuit
solutions for the communications industry. Our products are used to send and
receive signals in a variety of wireless and broadband communications
applications. Our innovative high frequency integrated circuits enable
manufacturers of communications equipment to enhance overall system performance
and reduce manufacturing cost and time to market.

    In the wireless market we focus on applications for cellular and personal
communications systems, or PCS, handsets. The global proliferation of wireless
communication has substantially enhanced the attractiveness of this market for
our products. According to Gartner Group's Dataquest, the worldwide market for
cellular/PCS wireless handsets has grown from 18.7 million units produced in
1993 to 175.4 million units in 1998. This represents a compound annual growth
rate of 56%. Dataquest projects that cellular/PCS handset production will exceed
550 million units per year by 2003. In the broadband market we focus on
applications for cable television systems, cable modems and fiber optic
communication systems. We believe the broadband communications market offers
significant growth opportunities driven by the emergence of interactive cable
systems offering increased video content, internet connection services and
telephony and fiber optic networks providing capacity for internet and
communications services. We serve these standards-driven markets with strong
customer relationships, radio frequency/microwave integrated circuit design
expertise, short development and production cycle time and competitive pricing.

    We design, develop and manufacture our integrated circuits primarily using
gallium arsenide, or GaAs, semiconductor material, which provides our products
with several advantages over products based on silicon. For example, GaAs-based
integrated circuits can operate at three to five times higher frequencies, have
lower noise figures, are better at facilitating integration of passive
components and are more power efficient than silicon-based products. The
industry transition from analog to digital data processing has resulted in
products that require faster digital integrated circuits which, in turn, require
higher performing analog interfaces to the outside world.

    We recently began production in our new six-inch analog GaAs wafer
fabrication facility, which we believe to be the first and only six-inch analog
GaAs wafer fabrication facility in our industry. Using a six-inch wafer allows
us to produce, at a small incremental cost, more than twice the integrated
circuit dice per wafer than can be produced from the current industry norm
four-inch wafer. In addition, we are in the process of developing products using
Heterojunction Bipolar Transistor or HBT technology, which will reduce design
complexity and power usage for our next-generation power amplifiers. With our
strong fabrication capability, significant management experience and innovative
designs, we believe we can rapidly develop products in line with market
requirements.

    We believe our competitive advantages are our radio frequency/microwave
integrated circuit design, development and applications expertise, our
high-volume, low-cost GaAs technology manufacturing expertise, as well as our
strong working relationships with leading original equipment

                                       3

manufacturers in each of our target markets. Our principal customers, based on
net sales, include LM Ericsson AB, General Instrument Corp., Lucent
Technologies, Inc., Methode Electronics, Inc., Motorola Inc., Nortel Ltd.,
Scientific-Atlanta, Inc. and Toshiba Corp.

    Our goal is to become the leading supplier of radio frequency/microwave
integrated circuit solutions for the wireless and broadband markets. The key
elements of our strategy are to:

    - be first-to-market with proprietary value-added products that provide
      cost-effective integrated circuit solutions;

    - capitalize on our world class manufacturing capabilities;

    - forge new relationships and leverage existing customer relationships with
      original equipment manufacturers; and

    - pursue strategic acquisitions and alliances to gain access to and benefit
      from complementary technologies.

                                  RISK FACTORS

    BEFORE PURCHASING SHARES, YOU SHOULD CAREFULLY CONSIDER THE RISK FACTORS
DESCRIBED BELOW. IF ANY OF THE FOLLOWING RISKS ACTUALLY OCCURS, IT COULD
MATERIALLY ADVERSELY AFFECT OUR BUSINESS, FINANCIAL CONDITION AND RESULTS OF
OPERATIONS. THE RISKS AND UNCERTAINTIES DESCRIBED BELOW ARE NOT THE ONLY ONES WE
ARE FACING. WE MAY HAVE OTHER RISKS AND UNCERTAINTIES OF WHICH WE ARE NOT YET
AWARE OR WHICH WE CURRENTLY BELIEVE ARE IMMATERIAL THAT MAY ALSO IMPAIR OUR
BUSINESS OPERATIONS. IN LIGHT OF THESE RISKS AND UNCERTAINTIES, THE TRADING
PRICE OF OUR COMMON STOCK COULD DECLINE AND YOU MAY LOSE ALL OR PART OF THE
MONEY YOU PAID TO BUY OUR COMMON STOCK.

                                 BUSINESS RISKS

WE DEPEND ON A SMALL NUMBER OF CUSTOMERS; A LOSS OF OR A DECREASE IN PURCHASES
BY ONE OF THESE CUSTOMERS WOULD MATERIALLY AND ADVERSELY AFFECT OUR REVENUES.

    We receive most of our revenues from a few significant customers. Sales to
Ericsson, General Instrument and Qualcomm Personal Electronics accounted for
16%, 16% and 12%, respectively, of 1996 net sales, and 33%, 13% and 16%,
respectively, of 1997 net sales. Ericsson and General Instrument accounted for
34% and 17%, respectively, of 1998 net sales, and 40% and 21%, respectively, of
net sales during the six month period ended July 4, 1999. No other customer
accounted for greater than 10% of net sales during these periods. Substantially
all of our sales of wireless applications are to Ericsson. Our operating results
have been materially and adversely affected in the past by the failure of
anticipated orders to be realized and by deferrals or cancellations of orders as
a result of changes in customer requirements. If we were to lose Ericsson,
General Instrument or another major customer, or if sales to Ericsson, General
Instrument or another major customer were to decrease materially, our results of
operations would be materially and adversely affected. See "Business--Target
Markets and Products".

OUR BUSINESS COULD BE ADVERSELY AFFECTED BY OUR FAILURE TO DEVELOP AND MARKET
GAAS HBT TECHNOLOGY.

    We are developing GaAs HBT process technology to manufacture power
amplifiers and certain other integrated circuits. Some of our competitors
already offer products using this technology. We are pursuing our development
effort initially with a third party foundry. We hope to begin production of GaAs
HBT products in our own manufacturing facility in the year 2000. We cannot
assure you that our efforts will result in commercially successful GaAs HBT
products in a timely or cost effective manner, if at all. Our in-house design
efforts may be delayed or fail to deliver viable GaAs HBT products. Our third
party foundry may delay or fail to deliver GaAs HBT technology or products to
us. Our results of operations could be materially and adversely affected by our
failure to develop this technology. Even if we are successful, our customers may
purchase their GaAs HBT requirements from our competitors.

DECREASES IN OUR CUSTOMERS' SALES VOLUMES COULD RESULT IN DECREASES IN OUR SALES
VOLUMES.

    A substantial portion of our sales are derived from sales to original
equipment manufacturers. Where our products are designed into an original
equipment manufacturer's product, our sales volumes depend upon the commercial
success of the original equipment manufacturer's product. Our operating results
have been materially and adversely affected in the past by the failure of
anticipated orders to be realized and by deferrals or cancellations of orders as
a result of changes in demands for our customers' products.

WE WILL NEED TO KEEP PACE WITH RAPID PRODUCT AND PROCESS DEVELOPMENT AND
TECHNOLOGICAL CHANGES TO BE COMPETITIVE.

    Rapid changes in both product and process technologies characterize the
markets for our products. Because these technologies are continually improving,
we believe that our future success

                                       6
<PAGE>
will depend, in part, upon our ability to continue to improve our product and
process technologies and develop new products and process technologies. If a
competing technology emerges that is superior to our existing technology and we
are unable to develop and/or implement the new technology successfully or to
develop and implement a competitive and economic alternative technology, our
results of operations would be materially and adversely affected. We will need
to make substantial investments to develop these enhancements and technologies,
and we cannot assure you that funds for these investments will be available or
that these enhancements and technologies will be successful. See
"Business--Competition" and "--Research and Development".

OUR PRODUCTS HAVE EXPERIENCED RAPIDLY DECLINING UNIT PRICES.

    In each of the markets where we compete, prices of established products tend
to decline significantly over time. Accordingly, in order to remain competitive,
we believe that we must continue to develop product enhancements and new
technologies that will either slow the price declines of our products or reduce
the cost of producing and delivering our products. If we fail to do so, our
results of operations would be materially and adversely affected.

THE VARIABILITY OF OUR MANUFACTURING YIELDS MAY AFFECT OUR GROSS MARGINS.

    Our manufacturing yields vary significantly among products, depending on the
complexity of a particular GaAs integrated circuit's design and our experience
in manufacturing that type of GaAs integrated circuit. Although our process
technology uses standard silicon semiconductor manufacturing equipment,
aggregate production quantities of GaAs integrated circuits manufactured by us
and the GaAs integrated circuit industry in general have been relatively low
compared with silicon integrated circuit production volumes. We have in the past
experienced difficulties in achieving planned yields, which have adversely
affected our gross margins.

    Regardless of the process technology used, the fabrication of integrated
circuits is a highly complex and precise process. Problems in the fabrication
process can cause a substantial percentage of wafers to be rejected or numerous
integrated circuits on each wafer to be nonfunctional, thereby reducing yields.
These difficulties can include:

    - defects in masks, which are used to transfer circuit patterns onto our
      wafers;

    - impurities in the materials used;

    - contamination of the manufacturing environment; and

    - equipment failure.

    Because a large portion of our costs of manufacturing are relatively fixed
and average selling prices for our products tend to decline over time, it is
critical for us to improve the number of shippable integrated circuits per wafer
and increase the production volume of wafers in order to maintain and improve
our results of operations. Yield decreases can result in substantially higher
unit costs, which could materially and adversely affect our operating results
and have done so in the past. We cannot assure you that we will be able to
continue to improve yields in the future or that we will not suffer periodic
yield problems, particularly during the early production of new products or
introduction of new process technologies. In either case, our results of
operations could be materially and adversely affected. See
"Business--Manufacturing, Assembly and Testing".

DELAYS IN COMPLETING THE TRANSITION OF PRODUCTION FROM OUR FOUR-INCH WAFER
FABRICATION FACILITY TO OUR SIX-INCH WAFER FABRICATION FACILITY COULD RESULT IN
DELAYS IN PRODUCT SHIPMENTS AND A LOSS OF CUSTOMERS AS A RESULT OF SUCH DELAYS.

    Some of our customers are currently in the process of qualifying our
six-inch wafer fabrication facility. We expect qualification activities to be
completed by the end of 1999. We cannot assure you that all of our customers
will qualify our products produced in the six-inch wafer fabrication facility.

                                       7
<PAGE>
    We also face numerous risks in the successful operation of our new six-inch
wafer fabrication facility as well as in our overall production operations. We
will need to train and manage production personnel successfully in order to
effectively operate our new six-inch wafer fabrication facility.

    Our failure to accomplish any of the foregoing could result in delays in
product shipments, adversely affect our relations with our customers and have a
material and adverse effect on our results of operations.

WE MAY FACE CONSTRAINTS ON OUR MANUFACTURING CAPACITY WHICH WOULD LIMIT OUR
ABILITY TO INCREASE SALES VOLUMES.

    We believe that our new six-inch wafer fabrication facility should be able
to satisfy our production needs for the next twelve months. However, if
production volumes were to increase significantly from expected levels, we might
be required to hire, train and manage additional production personnel in order
to successfully increase production capacity at this facility. We cannot assure
you that we would be able to implement these changes successfully. A delay for
any reason in capacity increase would limit our ability to increase sales
volumes. In addition, if we fail to increase production and do not have
sufficient capacity to satisfy the demand for our products, our relationships
with customers could be harmed.

WE DEPEND ON FOREIGN SEMICONDUCTOR ASSEMBLY CONTRACTORS AND A LOSS OF AN
ASSEMBLY CONTRACTOR COULD RESULT IN DELAYS OR REDUCTIONS IN PRODUCT SHIPMENT.

    We do not assemble our integrated circuits or our multi-chip modules.
Instead, we provide the GaAs integrated circuit dice and, in some cases,
packaging and other components to assembly vendors located primarily in Asia. We
maintain one qualified service supplier for each assembly process. If we are
unable to obtain sufficient high quality and timely assembly service, or if we
lose any of our current assembly vendors, we would experience delays or
reductions in product shipment, and/or reduced product yields that could
materially and adversely affect our results of operations.

WE MAY FACE CONSTRAINTS ON OUR TEST CAPACITY WHICH COULD RESULT IN MANUFACTURING
DELAYS.

    We use automated test equipment that is currently in short supply. As a
result, we need to order the test equipment from the manufacturer far in advance
of our anticipated need. We cannot assure you that we can obtain the appropriate
equipment in a timely or cost effective manner. Our inability to obtain
appropriate test equipment in a timely manner could result in manufacturing
delays which would have a material and adverse effect on our results of
operations.

THE SHORT LIFE CYCLES OF SOME OF OUR PRODUCTS MAY LEAVE US WITH OBSOLETE OR
EXCESS INVENTORIES.

    The life cycles of some of our products depend heavily upon the life cycles
of the end products into which our products are designed. We estimate that
current life cycles for cellular and PCS telephone handsets, and in turn our
cellular and PCS products, are approximately 12 to 24 months. Products with
short life cycles require us to manage closely production and inventory levels.
We cannot assure you that obsolete or excess inventories, which may result from
unanticipated changes in the estimated total demand for our products and/or the
estimated life cycles of the end products into which our products are designed,
will not affect us. In 1998, we recorded a significant charge for obsolete
inventory. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations--1998 Compared to 1997--Gross Margin".

                                       8
<PAGE>
SOURCES FOR CERTAIN COMPONENTS, MATERIALS AND EQUIPMENT ARE LIMITED WHICH COULD
RESULT IN DELAYS OR REDUCTIONS IN PRODUCT SHIPMENTS.

    We do not manufacture any of the starting wafers or packaging components
used in the production of our GaAs integrated circuits. Starting wafers and
packaging components are available from a limited number of sources. If we are
unable to obtain these wafers or components in the required quantities and
quality we could experience delays or reductions in product shipments, which
would materially and adversely affect our results of operations. Although we
have not experienced any significant difficulty to date in obtaining wafers or
components, we cannot assure you that shortages will not arise in the future.

    We depend on a limited number of vendors to supply equipment used in our
manufacturing processes. When demand for semiconductor manufacturing equipment
is high, lead times for delivery of such equipment can be substantial. We cannot
assure you that we would not lose potential sales if required manufacturing
equipment is unavailable and, as a result, we are unable to maintain or increase
our production levels. See "--We may face constraints on our manufacturing
capacity which would limit our ability to increase sales volumes".

OUR INTERNATIONAL SALES AND OPERATIONS INVOLVE FOREIGN EXCHANGE RISKS.

    Sales to customers located outside North America (based on shipping
addresses and not on the locations of ultimate end users) accounted for
approximately 65%, 57%, 58% and 61% of total net sales for 1996, 1997, 1998 and
the six month period ended July 4, 1999, respectively. We expect that revenues
derived from international sales will continue to represent a significant
portion of our total net sales. In addition, independent third parties located
in Asia supply a substantial portion of the starting wafers and packaging
components that we use in the production of GaAs integrated circuits, and
assemble nearly all of our products.

    Due to our reliance on international sales and on foreign suppliers and
assemblers, we are subject to risks of conducting business outside of the United
States, including primarily those arising from currency fluctuations, which
could affect the price of our products and/or the cost of producing them.

OUR ORGANIZATIONAL DOCUMENTS AND DELAWARE LAW MAY MAKE IT HARDER FOR US TO BE
ACQUIRED WITHOUT THE CONSENT AND COOPERATION OF OUR BOARD OF DIRECTORS AND
MANAGEMENT.

    Several provisions of our certificate of incorporation and our by-laws may
deter or prevent a takeover attempt, including a takeover attempt in which the
potential purchaser offers to pay a per share price greater than the current
market price for our common stock. These provisions include:

    - PREFERRED STOCK--our board of directors can issue preferred stock senior
      to our common stock at any time. This may make it more difficult and more
      expensive to acquire us;

    - STAGGERED BOARD--only a minority of the total number of board members can
      be elected each year. This may make it more difficult for a potential
      purchaser to elect enough directors to assure control of ANADIGICS; and

    - STOCKHOLDER RIGHTS PLAN--our stockholder rights plan may make it more
      difficult and more expensive to acquire us, unless the stockholder rights
      are first redeemed by our board.

    In addition, we are subject to Section 203 of the Delaware General
Corporation Law which restricts business combinations with some stockholders
once the stockholder acquires 15% or more of our common stock.

                                 INDUSTRY RISKS

WE FACE INTENSE COMPETITION WHICH COULD RESULT IN A DECREASE OF OUR PRODUCTS'
PRICES AND SALES.

    The semiconductor industry is intensely competitive and is characterized by
rapid technological change. We compete with manufacturers of discrete GaAs and
silicon semiconductors and with manufacturers of GaAs and silicon integrated
circuits. We expect increased competition from:

    - other GaAs integrated circuit manufacturers who may replace us as a single
      source supplier to an original equipment manufacturer or otherwise dilute
      our sales to an original equipment manufacturer;

    - silicon analog integrated circuit manufacturers; and

    - companies which may penetrate the radio frequency/microwave integrated
      circuit communications market with other technologies, such as those based
      on silicon germanium.

    In addition, some of our customers compete with us and we have lost business
in the past to this type of competition. We expect that sales of low data rate
fiber optic products used in SONET fiber optic transmissions could decline
significantly over the next few quarters, as current customers begin to obtain
these products from in-house supply sources.

    Increased competition could result in:

    - decreased prices of GaAs integrated circuits;

    - reduced demand for our products; and

    - a reduction in our ability to recover development-engineering costs.

Any of these developments could materially and adversely affect our results of
operations.

    Most of our current and potential competitors, which include Alpha
Industries, Inc., Conexant Systems, Inc., Fujitsu Compound Semiconductor Inc.,
Hitachi Ltd., Lucent Technologies, Inc., Maxim Integrated Products, RF Micro
Devices, Inc., Royal Philips Electronics, N.V., TriQuint Semiconductor, Inc. and
Vitesse Semiconductor Corporation, have significantly greater financial,
technical, manufacturing and marketing resources than we do. We cannot assure
you that we will be able to compete successfully with our existing or new
competitors. See "Business-- Competition".

OUR OPERATING RESULTS CAN VARY SIGNIFICANTLY.

    The semiconductor industry has been characterized by cyclicality. The
industry has experienced significant economic downturns at times, involving
diminished product demand, accelerated erosion of average selling prices and
production over-capacity. Although the semiconductor industry in general, and
the portion of the industry serving the communications industry in particular,
are currently experiencing a period of increased demand, we cannot assure you
that these conditions will continue. We may experience substantial period to
period fluctuations in future operating results. You should not rely on our
operating results for the six months ended July 4, 1999 as an indicator of our
results for the year ending December 31, 1999.

WE MAY NOT BE SUCCESSFUL IN AVOIDING CLAIMS THAT WE INFRINGE ON THE INTELLECTUAL
PROPERTY RIGHTS OF OTHERS OR IN PROTECTING OUR OWN INTELLECTUAL PROPERTY RIGHTS.

    Our success depends in part on our ability to obtain patents and copyrights,
maintain trade secret protection and operate without infringing on the
proprietary rights of third parties.

    As is typical in the semiconductor industry, we have been notified, and may
be notified in the future, that we are infringing on certain patent and/or other
intellectual property rights of others. If it

                                       10
<PAGE>
is determined that we have infringed on others' intellectual property rights, we
cannot assure you that we would be able to obtain any required licenses on
commercially reasonable terms.

    Currently, there are two unresolved notices claiming that we are infringing
intellectual property rights of others. We intend to defend ourselves vigorously
against these allegations. One such assertion is LEMELSON V. ANADIGICS, ET AL.,
brought against Lucent Technologies, Cypress Semiconductor, LSI Logic Corp. and
a number of other companies in the U.S. District Court for the District of
Arizona in February 1999. The other is an assertion by Rockwell International
Corporation that we are infringing upon a patent on the processing of
semiconductor wafers. The patent will expire in March 2000.

    In addition to patent and copyright protection, we also rely on trade
secrets, technical know-how and other unpatented proprietary information
relating to our product development and manufacturing activities which we seek
to protect, in part, by confidentiality agreements with our collaborators and
employees. We cannot assure you that these agreements will not be breached, that
we would have adequate remedies for any breach or that our trade secrets and
proprietary know-how will not otherwise become known or independently discovered
by others. See "Business--Patents, Licenses and Proprietary Rights" and "--Legal
Matters".

                         RISKS RELATED TO THIS OFFERING

THE VOLATILITY OF OUR STOCK PRICE COULD AFFECT YOUR INVESTMENT IN OUR STOCK.

    The market price of our stock has fluctuated widely. Between January 29,
1998 and October 8, 1998 our common stock price dropped from approximately
$33.81 to $5.13 per share. Between October 8, 1998 and July 14, 1999 the price
of our common stock rose from approximately $5.13 to $39.25 per share. The
current market price of our common stock may not be indicative of future market
prices and we may not be able to sustain or increase the value of your
investment in our common stock.

IN THE PAST, WE HAVE MADE PUBLIC STATEMENTS REGARDING OUR HOPES AND EXPECTATIONS
FOR OUR FUTURE REVENUES. THE CONTEXT IN WHICH THESE STATEMENTS WERE MADE MAKES
THEM HIGHLY SPECULATIVE AND OUR ACTUAL RESULTS MAY VARY SIGNIFICANTLY FROM THOSE
STATED. AS A RESULT, YOU SHOULD BASE YOUR INVESTMENT DECISION ONLY UPON THE
INFORMATION IN THIS PROSPECTUS AND NOT ON ANY OTHER PUBLIC STATEMENTS.

    The February 8, 1999 and the August 30, 1999 editions of Electronic Buyers'
News referred to statements made by Dr. Bami Bastani, our Chief Executive
Officer, regarding our future revenues. In particular, the articles referred to
Dr. Bastani's statement:

    - that in setting ANADIGICS' targets, he hopes to double ANADIGICS' revenue
      every two years (Electronic Buyers' News, February 8, 1999); and

    - AT&T Corp.'s push into the cable communications business is sparking
      interest in the industry's potential and as a result he sees revenue
      growing at nearly 35% per year in ANADIGICS' cable set-top and cable-model
      business (Electronic Buyers' News, August 30, 1999).

    The context within which Dr. Bastani's forward-looking statements were made
makes them highly speculative, based on numerous assumptions and subject to
numerous risks and uncertainties, any of which could cause our actual revenues
to be less than those referenced in these articles. ANADIGICS does not intend
for potential investors to rely upon these statements in making their investment
decisions. You should base your investment decision solely upon the information
contained in this prospectus and not upon the statements above or similar
statements.

                           FORWARD-LOOKING STATEMENTS

    This prospectus contains "forward-looking statements" within the meaning of
the Private Securities Litigation Reform Act of 1995. These statements include,
among other things, statements concerning:

    - the development of new communication technologies and services;

    - the trend in communication systems toward higher operating frequencies;

    - the evolution of communication systems from analog to digital modulation;

    - the growth opportunities in markets for our products;

    - the manufacturing capability of our new six-inch wafer fabrication
      facility;

    - descriptions of our plans and objectives for our business and the
      assumptions that underlie these plans and objectives;

    - our future financial performance; and

    - other statements regarding matters that are not historical facts.

    They also include statements relating to acquisitions and other business
development activities, future capital expenditures, manufacturing capacity,
financing sources and availability and the effects of regulation and
competition. We base these statements on our current expectations, but many
factors and uncertainties, including changes in the securities or financial
markets or in general economic conditions, the availability of equity and debt
financing, competition and the other factors described under "Risk Factors"
above and elsewhere in this prospectus could cause actual results to differ
materially from those described in the forward-looking statements.

    We caution you not to place undue reliance on any forward-looking
statements.

                                USE OF PROCEEDS

    The net proceeds from the sale of the 3,000,000 shares of our common stock
offered with this prospectus after deducting the underwriting discount and
estimated offering expenses are estimated to be $87,647,000, or $100,869,500 if
the underwriters' over-allotment option is exercised in full, assuming an
initial price to public of $31.00 per share. We expect to use the net proceeds
from this offering for general corporate purposes, including capital
expenditures and working capital. We may use all or a portion of the net
proceeds to acquire complementary businesses or technologies. However, we
currently have no agreements or understandings with respect to any acquisitions.
Pending these uses, we intend to invest the net proceeds from this offering in
investment-grade, income-producing securities.

                                DIVIDEND POLICY

    We have never paid cash dividends on our capital stock. Our bank credit
agreement prohibits the payment of cash dividends without the consent of our
bank credit agreement lender. We currently anticipate that we will retain all
available funds for use in the operation and expansion of our business, and do
not anticipate paying any cash dividends in the foreseeable future.

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS

OVERVIEW

    We were organized in 1984 and initially focused on the development and
manufacture of GaAs integrated circuits for low-volume defense and aerospace
applications. In 1988 we began shifting our strategy to focus on radio
frequency/microwave communications systems for high-volume applications, and
began production for these applications in 1989. In 1992 we introduced
integrated circuits for cable television. In late 1994 we entered the wireless
communications market with the introduction of cellular telephone integrated
circuits. In 1998 we expanded our fiber optic product offerings with the
introduction of transimpedance amplifiers for the gigabit ethernet market.

    In the next few years, we believe there are opportunities to develop
integrated circuits in silicon or silicon germanium technology that improves the
performance of silicon by improving silicon's electron mobility which would
enhance our GaAs integrated circuits in modules. The recently established RF
Standard Products Group at ANADIGICS will be exploring the use of these
technologies in wireless applications.

    We strive to achieve market advantage through the application of our radio
frequency/ microwave design and application knowledge. With our design expertise
we have led the industry with the introduction of innovative products. Recent
examples include dual-band power amplifiers for use in wireless handsets, cable
television 256 QAM upconverters and cable television reverse amplifiers, all of
which offer greater levels of product performance and reduce original equipment
manufacturers' production costs.

    We aim to achieve cost advantage through the scale and efficiency of our
manufacturing operations. We recently began production in our new six-inch
analog GaAs wafer fabrication facility, which we believe to be the first and
only six-inch analog GaAs wafer fabrication facility in our industry. Using a
six-inch wafer allows us to produce, at a small incremental cost, more than
twice the integrated circuit dice per wafer than can be produced from the
industry norm four-inch wafer.

    SIX MONTHS 1999 COMPARED TO SIX MONTHS 1998

    NET SALES.  Net sales during the six month period ended July 4, 1999
increased 34% to $55.6 million from $41.5 million in the six month period ended
June 28, 1998. Sales of integrated circuits for cellular and PCS applications
increased 36% during the six month period ended July 4, 1999 to $22.5 million
from $16.5 million in the six month period ended June 28, 1998 as demand for our
dual-band power amplifiers increased.

    Sales of integrated circuits for cable and broadcast applications increased
25% during the six month period ended July 4, 1999 to $20.5 million from $16.4
million in the six month period ended June 28, 1998. Included in the sales of
integrated circuits for cable and broadcast applications are sales of low noise
block converters (which we ceased production of during the third quarter of
1998) of $0.7 million and $2.8 million during the six month period ended July 4,
1999 and June 28, 1998, respectively. The increase in sales of integrated
circuits for cable and broadcast applications during the six month period ended
July 4, 1999 was due to increases in demand for our chip sets used in digital
set-top converters and cable modems, and our line amplifiers used as a repeater
in cable television distribution networks.

    Sales of integrated circuits for fiber optic telecommunication and data
communication applications increased 52% during the six month period ended July
4, 1999 to $12.5 million from $8.2 million in the six month period ended June
28, 1998 as demand for transimpedance amplifiers for SONET fiber optic
telecommunication applications and data communication applications increased. We
expect increased competition from internally sourced silicon integrated circuits
at certain of our customers for SONET OC-12 and OC-24 fiber optic transimpedance
amplifiers. Increased competition could result in decreased prices of our
integrated circuits and/or reduced demand for our products. Sales of SONET OC-12
and OC-24 fiber optic transimpedance amplifiers were approximately $4.5 million
during the first half of 1999.

    Engineering service sales, which reflect customers' contributions to
research and development, decreased $0.3 million during the six month period
ended July 4, 1999 to $0.1 million from $0.4 million in the six month period
ended June 28, 1998.

    Generally, selling prices for same product sales were lower during the six
month period ended July 4, 1999 compared to the six month period ended June 28,
1998.

    GROSS MARGIN.  Gross margin during the six month period ended July 4, 1999
declined to 35.0% from 35.8% in the six month period ended June 28, 1998.
Excluding the accelerated depreciation expense of $5.3 million, gross margin
during the six month period ended July 4, 1999 was 44.5%. The accelerated
depreciation expense was due to a reduction in the useful lives of the
fabrication facility equipment and leasehold improvements with original lives
ranging from five to 20 years that were reduced to a life of nine months
beginning October 1, 1998. The reduction in estimated useful life followed our
October 1998 decision to close our four-inch wafer fabrication facility. The
accelerated depreciation expense associated with the closing of our four-inch
wafer fabrication facility that was recorded during the first half of 1999, was
mostly offset by increased sales volume, manufacturing cost structure
improvements and improved yields.

    RESEARCH AND DEVELOPMENT.  ANADIGICS-funded research and development expense
increased 23% during the six month period ended July 4, 1999 to $12.0 million
from $9.8 million in the six month period ended June 28, 1998. The increase was
primarily attributable to increased research and development (1) of integrated
circuits for cellular and PCS, cable television and fiber optic applications and
(2) of new process technologies. As a percentage of sales, ANADIGICS-funded
research and development decreased to 21.6% during the six month period ended
July 4, 1999 from 23.5% in the six month period ended June 28, 1998.

                                       17
<PAGE>
    SELLING AND ADMINISTRATIVE.  Selling and administrative expenses increased
37% during the six month period ended July 4, 1999 to $8.7 million from $6.4
million in the six month period ended June 28, 1998. The increase was due in
part to increases in performance-related compensation costs, consulting fees and
costs related to our marketing activities. As a percentage of sales, selling and
administrative expenses increased to 15.7% during the six month period ended
July 4, 1999 from 15.5% in the six month period ended June 28, 1998.

    RESTRUCTURING CHARGES.  During the first quarter of 1998, we recorded a
charge of $1.1 million associated with a reduction in staff of 100 employees.
The employees who were involuntarily terminated were notified, received
information regarding their benefits arrangement and were severed on March 2,
1998. The terminated employees represented all areas of our operations,
including production, research and development, and selling and administrative
areas. The reduction in work force charge primarily consisted of severance pay,
extended medical coverage and outplacement service costs. The $1.1 million was
paid during 1998.

    INTEREST INCOME, NET.  Interest income, net decreased 19% during the six
month period ended July 4, 1999 to $1.0 million from $1.2 million in the six
month period ended June 28, 1998.

    PROVISION FOR LITIGATION SETTLEMENT.  We recorded a provision for litigation
settlement of $6.9 million during the second quarter of 1999, as we reached an
agreement in principle with the plaintiffs' counsel to settle a consolidated
class action lawsuit and a derivative lawsuit. The $6.9 million provision
consists of an expected payment of $11.75 million offset by insurance proceeds
of $5.3 million, and $0.4 million of additional legal, settlement, notification
and court related fees, of which $0.2 million was paid as of July 4, 1999.

    BENEFIT FOR INCOME TAXES.  The benefit for income taxes during the six month
period ended July 4, 1999 was recorded at an estimated annual effective tax rate
of 37.0% of the loss before income taxes.

    1998 COMPARED TO 1997

    NET SALES.  Net sales during 1998 decreased 16% to $86.1 million from $102.5
million in 1997. Net sales consist of product sales and engineering service
sales. Net product sales decreased 15% to $85.4 million in 1998 from $101.0
million in 1997. Engineering service sales, which reflect customers'
contributions to research and development, decreased 54% during 1998 to $0.7
million from $1.5 million in 1997.

    Sales of integrated circuits for cellular and PCS applications decreased 44%
during 1998 to $33.7 million from $59.7 million during 1997. The lower demand
was due to several factors, including increased competition, a shift in demand
to lower cost phones not using our parts, customer delays in ramp-up of new
generation dual-band phones using our new parts and, in part, the effect of the
Asian financial crisis on the wireless communications markets.

    Sales of integrated circuits for cable and broadcast applications increased
36% during 1998 to $28.3 million from $20.8 million in 1997. The increase in
sales of integrated circuits for cable and broadcast applications during 1998
was due to increases in demand for our integrated circuits used in digital
set-top converters and cable modems, and our integrated circuit line amplifier
used as a
repeater in hybrid fiber coaxial distribution networks.

    Sales of integrated circuits for fiber optic telecommunication and data
communication applications increased 53% during 1998 to $17.6 million from $11.5
million in 1997. The increase was primarily due to an increase in demand for
transimpedance amplifiers for SONET fiber optic telecommunication applications
and sales of a new family of integrated circuits for data

                                       18
<PAGE>
communication applications. ANADIGICS expects increased price competition for
lower data rate fiber optic telecommunications products from other silicon-based
solution providers during 1999.

    Sales of integrated circuits for direct broadcast satellite applications
decreased 36% during 1998 to $5.7 million from $9.0 million in 1997. During the
third quarter of 1998, we decided to cease production of our low noise block
converter integrated circuits that were used in direct broadcast satellite
applications because of reduced demand for low noise block converter integrated
circuits and the effects of the Asian financial crisis.

    Generally, selling prices for same product sales were lower during 1998
compared to 1997.

    GROSS MARGIN.  Gross margin during 1998 declined to 23.1% from 45.3% in
1997. The reduction in gross margin was primarily due to increased inventory
reserves totalling $13.8 million, including a special charge of $6.6 million
(substantially all of which was scrapped prior to December 31, 1998) and
accelerated depreciation charges (related to the planned closing of our existing
wafer fabrication facility) of $2.7 million that were recorded during 1998. The
inventory special charges (which were primarily work-in-progress and finished
goods) consisted of the following: $3.4 million of older generation, single-band
power amplifier integrated circuits used in cellular applications, $2.1 million
of low noise block converter integrated circuits used in direct broadcast
satellite applications, and $1.1 million of older generation line amplifiers
used in cable television applications. ANADIGICS was aggressively attempting to
sell these integrated circuits in certain markets (primarily secondary
communications markets in Asia). ANADIGICS experienced limited success in
selling these integrated circuits during 1998 and reevaluated our selling
efforts and the potential markets for these products during 1998. Based upon
this reevaluation, we decided during the third quarter of 1998 that we would
curtail our efforts to sell these products.

    The remaining portion of the reserves recorded during 1998 of $7.2 million
(which were primarily work-in-progress and finished goods) consists of inventory
reserves for excess or obsolete inventory which were recorded based upon our
on-going inventory analysis during 1998.

    We are currently not aware of any known or expected additional inventory
reserves.

    Lower factory utilization and higher fixed costs associated with our new
test and manufacturing administration facilities placed into service during the
second quarter of 1998 also contributed to the reduction in gross margin during
1998 compared to 1997.

    RESEARCH AND DEVELOPMENT.  ANADIGICS-funded research and development
expenses increased 12% during 1998 to $18.8 million from $16.8 million in 1997.
The increase was primarily attributable to increased research and development of
integrated circuits for fiber optic and cellular and PCS applications. As a
percent of sales, ANADIGICS-funded research and development increased to 21.9%
during 1998 from 16.4% in 1997.

    SELLING AND ADMINISTRATIVE.  Selling and administrative expenses increased
6% during 1998 to $12.9 million from $12.1 million in 1997. The increase was due
in part to executive relocation costs, an increase in operating costs associated
with our information systems, and other consulting costs. As a percentage of
sales, selling and administrative expenses increased to 15.0% during 1998 from
11.8% in 1997.

    RESTRUCTURING CHARGES.  In connection with our plan to lower manufacturing
costs and streamline our manufacturing operations, we recorded restructuring
charges totaling $7.1 million during 1998. The restructuring charges consisted
of writedowns of impaired assets of $4.5 million, reductions in force of $1.6
million and wafer fabrication facility shutdown and removal costs of $1.0
million.

    WRITEDOWNS OF IMPAIRED ASSETS.  We evaluated the on-going value of certain
assets. Based upon our plan to dispose of certain assets with a carrying amount
of $4.6 million and our estimate of sales value, net of related costs to sell,
at $0.1 million, we recorded an impairment loss of $4.5 million, which consisted
of the following items (in millions):

    REDUCTIONS IN FORCE.  We recorded charges of $1.1 million during the first
quarter of 1998 and $0.5 million during the fourth quarter of 1998 associated
with reductions in our workforce. The workforce reduction charges primarily
consisted of severance pay, extended medical coverage and outplacement service
costs for approximately 165 employees primarily involved in our production
operations. Approximately $1.1 million of severance pay, extended medical
coverage, and outplacement service costs were paid through December 31, 1998 for
the termination of approximately 120 employees. We expect to pay the remaining
liability of $0.5 million during the first half of 1999.

    FACILITY SHUTDOWN AND REMOVAL COSTS.  We recorded charges of $1.0 million
associated with the shutdown and removal of our existing wafer fabrication
facility. See "Business--Manufacturing, Assembly and Testing".

    INTEREST INCOME, NET.  Interest income, net decreased 29% during 1998 to
$2.3 million from $3.2 million in 1997. The reduction in interest income, net of
$0.9 million was primarily due to a lower amount of investments during 1998,
caused by plant and equipment purchases that were primarily for our new wafer
fabrication facility.

    BENEFIT FOR INCOME TAXES.  We recorded a benefit for income taxes during
1998 of $7.2 million, or 42.9% of the loss before income taxes. The benefit for
income taxes primarily related to the 1998 federal and state net operating
losses, federal and state research and development credits and state
manufacturing credits, all of which we plan to carry forward.

    1997 COMPARED TO 1996

    NET SALES.  Net sales during 1997 increased 49% to $102.5 million from $68.9
million in 1996. Net sales consist of product sales and engineering service
sales. Net product sales increased 54% to $101.0 million from $65.7 million in
1996. Engineering service sales decreased 51% during 1997 to $1.5 million from
$3.2 million in 1996.

    Sales of integrated circuits for cellular and PCS applications increased
144% during 1997 to $59.7 million from $24.5 million in 1996 as a result of
higher volumes. During 1997, we sold power amplifier integrated circuits for all
three major wireless digital standards, including GSM, TDMA and CDMA. As a
percentage of total sales, sales of integrated circuits for the GSM, TDMA and
CDMA frequency bands were approximately 37%, 24% and 28%, respectively in 1997.
Sales of integrated circuits for cable television applications in 1997 increased
51% to $20.8 million from $13.8 million in 1996 as demand for integrated
circuits used in set top converters and cable modems increased.

    Sales of integrated circuits for fiber optic SONET, SDH and asynchronous
transfer mode telecommunication applications decreased 1% during 1997 to $11.5
million from $11.6 million in 1996. Sales of integrated circuits for DBS
television applications decreased 43% during 1997 to

                                       20
<PAGE>
$9.0 million from $15.8 million in 1996 as demand from European manufacturers of
direct broadcast satellite equipment for the European market decreased.

    Generally, selling prices for same product sales were lower in 1997 compared
to 1996.

    GROSS MARGIN.  Gross margin during 1997 increased to 45.3% from 43.5% in
1996. The increase was due to manufacturing efficiencies, which resulted in part
from the conversion from three-inch wafers used in 1996 to four-inch wafers used
during 1997, higher production volume and improved production yields. These
factors were partially offset by additional costs associated with assembly and
packaging quality problems on certain products that were incurred during the
fourth quarter of 1997 and a shift in sales mix to lower margin products during
1997 compared to 1996.

    RESEARCH AND DEVELOPMENT.  Research and development expenses we sponsored
increased 39% during 1997 to $16.8 million from $12.0 million during 1996. The
increase was primarily attributable to increased research and development of
integrated circuits for cellular, PCS and other wireless applications. As a
percentage of sales, these expenses declined to 16.4% during 1997 from 17.5%
during 1996.

    During 1997, approximately two-thirds of our research and development
expenses were for the development of integrated circuits for cellular, PCS and
other wireless applications, compared to approximately one-half in 1996.

    SELLING AND ADMINISTRATIVE.  Selling and administrative expenses increased
48% during 1997 to $12.1 million from $8.2 million during 1996. As a percentage
of sales, these expenses declined during 1997 to 11.8% from 11.9% during 1996.
Administrative expenses increased 64% in 1997 due in part to increased
compensation, recruiting and training costs. Selling expenses increased by 32%
in 1997 due to staffing increases primarily associated with the expansion of our
wireless integrated circuit sales efforts, increased consulting fees and
increased sales commission expense.

    INTEREST INCOME, NET.  Interest income increased $1.7 million during 1997 to
$3.4 million from $1.7 million during 1996. The increase was due to higher
invested cash balances following the receipt of proceeds from the public
offering of our common stock in February 1997. Interest expense decreased by
$0.2 million during 1997 to $0.2 million from $0.4 million during 1996 on lower
levels of indebtedness.

    PROVISION (BENEFIT) FOR INCOME TAXES.  The provision for income taxes during
1997 was $5.4 million, or 26.2% of pre-tax income. The benefit for income taxes
in 1996 was $0.9 million, or 8% of pre-tax income. The provision for income
taxes in 1997 included a $1.9 million reduction in the valuation allowance,
which is explained below, which had been recorded prior to 1997 with respect to
deferred tax assets (primarily federal net operating loss carryforwards). The
benefit for income taxes in 1996 arose from a $5.2 million reduction in the
valuation allowance, which had been recorded prior to 1996 with respect to
deferred tax assets (primarily net operating loss carryforwards).

    As of December 31, 1996, we had net deferred tax assets of approximately
$15.7 million, which primarily consisted of federal net operating loss
carryforwards of $12.6 million and general business credit carryforwards of $0.8
million. A valuation allowance of $10.8 million was provided for the federal net
operating loss and general business credit carryforwards as of December 31,
1996. As of December 31, 1997, we had net deferred tax assets of approximately
$3.5 million and no valuation allowance.

    The reductions in the net deferred tax assets and the valuation allowance
from 1996 to 1997 primarily resulted from: (1) our determination that certain
pre-1989 federal net operating loss and general business credit carryforwards
that were severely restricted under Section 382 of the Internal Revenue Code
would not be utilized prior to their expiration, and (2) the results of an
Internal

                                       21
<PAGE>
Revenue Service examination completed in 1997 which resolved uncertainties
regarding possible limitations of federal net operating loss carryforwards and
general business credit carryforwards generated between 1989 and 1992. We had
been providing taxes in 1996 and prior years as if the use of these federal net
operating loss and general business carryforwards were restricted.

    The reduction in the pre-1989 net operating loss and general business credit
carryforwards noted above had no effect on net income. The reduction in the
federal net operating loss and general business credit carryforwards generated
between 1989 and 1992 resulted in a reduction of the current federal provision
for income tax expense. The effect of this reduction was an increase in net
income in 1997 of approximately $1.9 million.

LIQUIDITY AND SOURCES OF CAPITAL

    As of July 4, 1999, we had $25.3 million in cash and cash equivalents and
$18.3 million in marketable securities. We have $4.5 million of bank debt
outstanding as of the end of the second quarter of 1999. We entered into an
interest rate swap agreement, which effectively fixes the interest rate on this
debt at 7.09%. The swap effectively changed the variable interest rate of this
bank debt to a fixed rate for which the present value of the cash flow is
approximately the same. As of the end of the second quarter of 1999, we also
have available $15.0 million under a term loan facility. The term loan facility
drawdown period expires on July 1, 2001. The outstanding bank debt and the term
loan facility are subject to a number of financial covenants. Substantially all
of our assets are pledged as security for repayments of the outstanding bank
debt and borrowings, if any, under the term loan facility.

    Net cash provided by operating activities was $10.1 million during the six
month period ended July 4, 1999.

    Net cash used in investing activities (to purchase equipment) was $9.8
million during the six month period ended July 4, 1999.

    Net cash provided by financing activities was $1.0 million during the six
month period ended July 4, 1999. Cash provided by financing activities was
primarily from the issuance of our common stock from stock options exercised
during the period.

    We expect to spend approximately $30.0 million on equipment, furniture and
fixtures and leasehold improvements during the twelve month period ending June
30, 2000. At July 4, 1999, we have committed to purchase approximately $7.5
million of equipment, furniture and fixtures and leasehold improvements through
the remainder of 1999.

    We believe that our current cash and cash equivalent balances, together with
cash anticipated to be generated from operations and the equity offering
described in this prospectus will satisfy anticipated capital needs for the next
twelve months and beyond.

IMPACT OF YEAR 2000

    The year 2000 issue is the result of computer programs being written using
two digits rather than four to define the applicable year. Any of our computer
programs or hardware that have date-sensitive software or embedded chips may
recognize a date using "00" as the year 1900 rather than the year 2000. This
could result in a system failure or miscalculations causing disruptions of
operations, including, among other things, a temporary inability to process
transactions, send invoices or engage in similar normal business activities.

    Our year 2000 initiative is being managed by a senior team of internal staff
and outside consultants. The team's activities are designed to ensure that there
is no adverse effect on our core business operations and that transactions with
customers, suppliers, and financial institutions are fully supported.

                                       22
<PAGE>
    Over the past year, we have invested in new computer hardware and software
to improve our business operations. To date, we have upgraded the majority of
our critical information systems such that they are now year 2000 ready.
Remaining critical systems are on target for their year 2000 upgrades at the end
of September 1999. As a result of this effort, we do not believe that any year
2000-related failures of critical systems will cause a significant interruption
to our business.

    We have also completed a comprehensive review of our equipment and
facilities. Based on this review, we do not believe that any year 2000-related
failures of critical systems will result in a significant disruption to our
business. A number of minor upgrades will be completed by the end of September
1999.

    The total cost of the year 2000 project is estimated at $1.6 million and is
being funded through operating cash flows. Of the total project cost,
approximately $1.0 million is for the purchase of new hardware and software,
which will be capitalized. As of July 4, 1999 we have spent approximately $0.8
million on hardware and software purchases and the remaining amount represents
equipment purchases expected to be delivered and installed during the third
quarter of 1999. As of July 4, 1999 we have incurred and expensed approximately
$0.4 million, primarily for assessment of the year 2000 issue, development of a
modification plan and remediation efforts. The remaining $0.2 million is
expected to be incurred and expensed in the third quarter of 1999.
    We have contacted our significant suppliers and other third party vendors
with which we have a material relationship in order to determine whether those
entities have adequate plans in place to ensure their year 2000 readiness. We
have also reviewed public disclosures made by our material customers in order to
determine their year 2000 readiness. To date, we have not identified any major
issues with respect to our material customers, our significant suppliers or
other third party vendors.

    We believe that a "worst case" scenario would involve third parties'
failures to address year 2000 issues. Such failures could result in, but are not
limited to, any of the following:

    (1) our utility services are interrupted resulting in our inability to
       continue our manufacturing operations;

    (2) our shipping services are interrupted preventing us from getting our
       product to and from our off-shore packaging facility and to our customers
       on a timely basis; and

    (3) our off-shore assembly contractors operations are interrupted resulting
       in our inability to obtain our packaged products on a timely basis.

    As of July 4, 1999, we have not developed an overall contingency plan. We do
not intend on doing so unless, as a result of ongoing tests, we determine that
contingency plans are warranted. Based on our assessment to date and our
expectations that our year 2000 initiative will be substantially complete by the
end of September 1999, we believe that adequate time will be available to ensure
alternatives can be assessed, developed and implemented, if necessary, prior to
a year 2000 issue having a negative impact on our operations. However, we cannot
guarantee that such contingencies, if required, will be completed on a timely
basis. While we believe our efforts will be adequate to address our year 2000
concerns, there can be no guarantee that we will not experience unanticipated
negative consequences or material costs caused by undetected errors or defects
in the technology used in our internal systems or that third parties upon which
we rely will not experience similar negative consequences.

    Our products do not have specific date functions or date dependencies and
will operate according to specifications through the year 2000 and beyond.

IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS

    In June 1998, the FASB issued Statement No. 133, Accounting for Derivative
Instruments and Hedging Activities, which is required to be adopted in years
beginning after June 15, 2000. The statement permits early adoption as of the
beginning of any fiscal quarter after its issuance. We expect to adopt the new
statement effective January 1, 2001. The statement will require us to recognize
all derivatives on the balance sheet at fair value. Derivatives that are not
hedges must be adjusted to fair value through income. If a derivative is a
hedge, depending on the nature of the hedge, changes in the fair value of the
derivative will either be offset against the change in fair value of the hedged
asset, liability, or firm commitment through earnings, or recognized in other
comprehensive income until the hedged item is recognized in earnings. The
ineffective portion of a derivative's change in fair value will be immediately
recognized in earnings. We do not anticipate that the adoption of this statement
will have a significant effect on our results of operations or financial
position.

                                    BUSINESS

    We supply radio frequency/microwave integrated circuit solutions to the
communications industry, enabling manufacturers to enhance overall system
performance and reduce manufacturing cost and time to market. In the wireless
market we focus on applications for cellular and personal communications systems
handsets. In the broadband market we focus on applications (or solutions) for
cable television systems, cable modems and fiber optic communications systems.
We believe our competitive advantages are our design, development and
applications expertise, our high-volume, low-cost GaAs technology manufacturing
expertise and our strong working relationships with leading original equipment
manufacturers in our target markets.

    We design, develop and manufacture our integrated circuits primarily using
GaAs semiconductor material with MESFET and PHEMT process technologies. We are
currently in the process of developing products using HBT technology, which we
believe will reduce design complexity and power usage for our next-generation
power amplifiers. We recently began production in our new six-inch analog GaAs
wafer fabrication facility, which we believe to be the first and only six-inch
analog GaAs wafer fabrication facility in our industry. Using a six-inch wafer
allows us to produce, at a small incremental cost, more than twice the
integrated circuit dice per wafer than can be produced from the industry norm
four-inch wafer. With our strong fabrication capability, significant management
expertise and innovative designs, we believe we can rapidly develop products in
line with market requirements.

INDUSTRY OVERVIEW

    Over the last decade there have been remarkable developments in electronic
communications, as evidenced by the emergence of wireless communications,
internet services and digital television services. Radio frequency/microwave and
integrated circuit technologies have enabled increases in communications
capacity and significant reductions in systems costs. The wireless and broadband
communications markets are beneficiaries of current technological trends,
including higher frequencies, digital modulation and higher levels of electronic
integration.

    Wireless communications, led by cellular and PCS telephone services, are
growing rapidly and wireless services are replacing wireline telephone services
in some markets. According to Gartner Group's Dataquest, the worldwide market
for cellular/PCS wireless handsets has grown from 18.7 million units produced in
1993 to 175.4 million units in 1998. This represents a compound annual growth
rate of 56%. Dataquest projects that cellular/PCS handset production will exceed
550 million units per year in 2003.

    Broadband markets are also benefiting from these technological changes.
Cable television systems are moving from one-way analog TV signal distribution
systems to interactive digital systems offering increased and new video content,
internet connection services and telephony. The increased demand for
communication services, such as the internet, is also driving expansion of fiber
optic telecommunications networks.

    Given these developments, original equipment manufacturers are facing the
following challenges:

    - SHORTER CYCLE TIMES.  In the wireless communications market, handset
      manufacturers must bring new products to market quickly in order to
      maintain their market position. We see new handset platforms being
      introduced every six months;

    - NEED FOR LOW-COST PRODUCTS.  Handset and set-top boxes are increasingly
      becoming consumer-driven products. The wide use of these products forces
      original equipment manufacturers to offer them at attractive prices. As a
      result, suppliers of components must be cost effective in order for
      original equipment manufacturers to stay competitive; and

                                       25
<PAGE>
    - STRONGER SUPPLIER RELATIONSHIPS.  The digital, wireless, cable and fiber
      optic industries are standards driven. Companies in the communications
      industry must work very closely with their suppliers in order to develop
      new products. Companies therefore limit themselves to a small number of
      suppliers in order to keep their competitive advantages.

THE GAAS ADVANTAGE

    Over the past fourteen years, through our research and development efforts,
we have developed expertise in producing cost-effective GaAs-based integrated
circuits for high-volume commercial applications which offer the performance
attributes required for radio frequency/ microwave applications that are not
easily obtainable with silicon-based integrated circuits. GaAs transistors can
operate at frequencies up to three to five times greater than those possible
with silicon and therefore can handle the requirements of radio
frequency/microwave applications. GaAs integrated circuits have a lower noise
figure than silicon-based integrated circuits, providing increased sensitivity,
less distortion and interference and better dynamic range, thereby enabling
systems to handle a wide range of signal strengths. GaAs is a semi-insulating
material which facilitates integration of the passive components required in
radio frequency/microwave applications. Finally, GaAs integrated circuits used
in transmitter applications are also more power-efficient than silicon-based
circuits, allowing for longer battery life or use of smaller batteries.

OUR STRATEGY

    Our objective is to be the leading supplier of radio frequency integrated
circuits for the wireless and broadband communications markets. The cornerstone
of our strategy is to capitalize on opportunities in the wireless and broadband
communications markets by addressing applications which leverage our radio
frequency integrated circuit design and manufacturing expertise and our
established relationships with leading original equipment manufacturers in these
markets. The key elements of our strategy are to:

    BE FIRST-TO-MARKET WITH PROPRIETARY VALUE-ADDED PRODUCTS

    We intend to continue to design timely, cost-effective integrated circuit
solutions for our target markets. The combination of our experienced engineering
staff and our "quick-turn" wafer fabrication and assembly service allows us to
develop prototypes that can be ready for testing in less than one month. This
design efficiency contributes to customer satisfaction and allows us to improve
product designs rapidly for manufacturing efficiency. For example, we were the
first manufacturer to offer an integrated circuit chip set for tuner
applications in cable television set-top boxes. We were also the first
manufacturer to offer a dual-band power amplifier that combines the functions of
two power amplifiers for cellular handsets into a single integrated circuit.

    CAPITALIZE ON OUR WORLD CLASS MANUFACTURING CAPABILITIES

    We will continue to focus on improving manufacturing performance and
customer service, while reducing costs. We believe that we can effectively
control the critical phases of our production process in order to realize high
manufacturing yields, product quality and customer satisfaction. A key element
of our manufacturing strategy is our new six-inch fabrication facility. We
believe this new facility will provide increased manufacturing capacities at a
low incremental cost and will allow us to maintain short cycle times.

    FORGE STRONG CUSTOMER RELATIONSHIPS

    We have developed strong working relationships with our customers, many of
whom are leading original equipment manufacturers in their markets. Because our
target markets are standards-driven, customer relationships are important. We
have been working with Ericsson on wireless handsets since 1994 and with General
Instrument on cable set-top boxes since 1992.

                                       26
<PAGE>
These relationships provide us with product development opportunities and the
ability to anticipate future market needs. The rapid feedback we receive from
customers during the product design phase increases the likelihood that our
products will meet our customers' cost and performance requirements.

    PURSUE STRATEGIC ACQUISITIONS AND ALLIANCES

    We intend to pursue strategic acquisitions and alliances to expand and
improve upon our technologies, industry expertise, products and market share. We
expect that our alliances and acquisitions will be complementary to our current
businesses and will enhance our ability to work with leading original equipment
manufacturers to develop next generation solutions. We have formed strategic
alliances with several firms to accelerate our capabilities in our core wireless
and broadband markets. For example, we entered into an agreement with Global
Communication Semiconductors, Inc. to develop HBT products, which we anticipate
will accelerate our introduction of GaAs HBT products to the first half of 2000.
We also entered into an agreement with TEMIC Semiconductor GmbH to develop HBT
products suitable for fabrication with silicon germanium.

TARGET MARKETS AND PRODUCTS

    WIRELESS COMMUNICATIONS.  The wireless communications market is a growing,
dynamic market as a result of increasing demand for:

    - portable voice and data communications;

    - smaller, lighter, less expensive handsets;

    - reliable access and voice quality comparable to land lines; and

    - longer talktime and standby time.

    Our radio frequency integrated circuit products are used in transmitters and
receivers of cellular and PCS handsets where small size, multi-band operation
and low power consumption are key features. In the United States, there are two
primary digital cellular standards, TDMA and CDMA. GSM is the most widely
deployed digital standard in the world, with a high degree of acceptance in
Europe and Asia. In addition, some GSM systems have been deployed in North
America. We currently provide power amplifiers primarily for the TDMA and GSM
standards and plan to introduce power amplifiers for the CDMA standard in 2000.
We also offer infrastructure products for the GSM standard.

    We are actively developing single- and multi-band HBT power amplifier
modules for all major digital standards. HBT technology offers high efficiency
and low power consumption, and will allow our customers to build the transmitter
section of the wireless handset more easily and more quickly by reducing design
complexity and component counts. Initially we are developing our HBT products
using an external foundry. We intend to begin production of HBT wafers in our
own manufacturing facilities in the first half of 2000. We are also developing a
family of standard radio frequency switches targeting handset applications using
both GaAs MESFET and PHEMT technologies. We believe that the market for radio
frequency/microwave switches will grow rapidly with the move to multi-band,
multi-mode handsets.

                                       27

    Our principal customer in the wireless market is Ericsson. Ericsson
accounted for 16%, 33%, 34% and 40% of net sales during 1996, 1997, 1998 and the
six month period ended July 4, 1999, respectively. The following table sets
forth information regarding our principal products in the wireless
communications market:

    CABLE TELEVISION/CABLE MODEMS.  The trends that currently drive product
development in the cable television and cable modem markets are:

    - shift to digital cable television with interactive services;

    - demand for internet access; and

    - emergence of cable telephony.

    The convergence of these trends, enabled by digital transmission, creates
the need for innovative radio frequency integrated circuits for cable television
and cable modem applications.

    Our cable products are used in cable modem, cable television set-top box and
cable television infrastructure applications. Cable television systems, which
traditionally delivered one way analog television programming, limited to a few
channels, are increasingly used to deliver a wide array of interactive video and
other services, such as high speed internet access and telephony. In order to
support these new applications, cable system operators must upgrade the
bandwidth (i.e., capacity) of both the infrastructure and terminal equipment.
The new equipment must also be able to handle digital as well as analog
modulations.

    For cable modems and cable television set-top boxes we currently offer tuner
integrated circuits which can receive analog and digital signals in the 50-860
megahertz frequency band. Our reverse amplifiers are used in cable modems and in
cable set-top boxes which require a reverse path to provide interactivity. These
tuner and reverse amplifier integrated circuits enable our customers to
accelerate and simplify their designs, and reduce manufacturing complexity and
costs. We are actively engaged in developing integrated multi-chip double
conversion tuner modules. We expect that these modules will be cost-competitive
with single conversion tuners and will provide improved performance for cable
modem and other single-conversion tuner applications.

                                       28
<PAGE>
    We have also developed GaAs integrated circuit line amplifiers for use by
operators in 50-860 megahertz cable television distribution systems. We have
recently expanded our product offerings in this area by introducing line
amplifiers which operate at 24 volts.

    The following table sets forth information regarding our principal products
in the cable television/cable modems market:

    FIBER OPTIC MARKET.  Growth in the fiber optic market is being driven by:

    - rapid increase in data traffic driven by internet use;

    - increasing implementation of corporate local area networks which require
      high speed data transfer capability; and

    - ongoing upgrade of existing telecommunication and data communication
      systems with fiber optic systems.

    Fiber optic telecommunication systems use low-loss fiber optic cable to link
central office switches with one another and to connect the central office to
the serving area. Most telecommunication networks today are based on SONET
(United States and Japan) or SDH (Europe) standards. These standards require
high sensitivity, high bandwidth, and wide dynamic range receivers.

                                       29
<PAGE>
    The front end of most fiber optic receivers contains a photodetector and a
transimpedance amplifier. Our transimpedance amplifier integrated circuits are
used in both fiber optic telecommunications and data communications networks.
Our GaAs integrated circuit transimpedance amplifiers are designed to meet the
requirements of SONET systems covering data speeds of OC-3, OC-12, OC-24 and
OC-48. We also sell products for use in the growing DWDM systems. We are
currently developing GaAs PHEMT-based next generation transimpedance amplifiers
specifically for DWDM and 3 volt applications. For data communications receivers
we sell integrated photodiode and transimpedance amplifier products for the
short wavelength (850 nanometer) and long wavelength (1300 nanometer) gigabit
ethernet application. We are developing higher speed (2.5 gigabits per second)
receiver products for the gigabit ethernet market in anticipation of increased
data speeds.

    Fiber optic data communications systems use either fibre channel or gigabit
ethernet standards to achieve high-speed data transfer. Gigabit ethernet
standards are emerging as the most widely used standard in local area networking
situations. It addresses the need for very fast transfers of large volumes of
information and is effective in applications where large blocks of data must be
transferred within buildings and over short distances. We believe that demand
for gigabit ethernet solutions will grow substantially over the next few years.

    The following table sets forth information regarding our principal products
in the fiber optic market:

MARKETING, SALES, DISTRIBUTION AND CUSTOMER SUPPORT

    We sell our products primarily directly to our customers worldwide. We have
developed close working relationships with leading companies in the broadband
and wireless communications markets. During 1999, we are undertaking a major
initiative to expand our field sales force to provide local support to our
customers. We believe this is critical to our objective of expanding our
customer base, especially as we expand our product portfolio. We also
selectively use independent manufacturers' representatives and distributors to
complement our direct sales and customer support efforts.

    We believe that the technical nature of our products and markets demands an
extraordinary commitment to close relationships with our customers. The sales
and marketing staff, assisted by the technical staff and senior management,
visit prospective and existing customers worldwide on a regular basis, and
between visits both field and factory sales personnel communicate regularly with
our customers. We believe that these contacts are vital to the development of
close, long-term working relationships with our customers, and in obtaining
regular forecasts, market updates and information regarding technical and market
trends.

                                       30
<PAGE>
    Our design and applications engineering staff is actively involved with
customers during all phases of design and production by publishing and providing
our customers with engineering data, up-to-date product application notes,
communicating with our customers' engineers on a regular basis and assisting in
resolving technical problems by working with our customers' engineers both on
and off site. In most cases the design and applications engineers obtain
prototypes from our customers in order to troubleshoot and identify potential
improvements to the design in parallel with our customers' efforts. This
strategy helps our customers speed up their design process, achieve
cost-effective and manufacturable designs, and ensure a smooth transition into
high-volume production.

    Our policy is to provide our customers with applications engineering support
at our customers' factories throughout the world, generally within 48 hours of a
customer request. Our sales are typically made pursuant to customer purchase
orders, and such orders may be canceled by our customers without penalty.

MANUFACTURING, ASSEMBLY AND TESTING

    We have begun to fabricate our integrated circuits in our six-inch diameter
GaAs wafer fabrication facility in our new class 100 cleanroom in Warren, New
Jersey. Present production capacity is approximately 21,000 six-inch diameter
analog GaAs wafers per year. We are in the process of closing our existing
four-inch wafer fabrication facility. With additional equipment and staffing,
the six-inch fabrication facility could run up to approximately 26,000 six-inch
wafers per year. See "Risk Factors--We may face constraints on our manufacturing
capacity which would limit our ability to increase sales volumes" and "--Delays
in completing the transition of production from our four-inch wafer fabrication
facility to our six-inch wafer fabrication facility could result in delays in
product shipments and a loss of customers as a result of such delays".

    Our wafer processing technologies have been developed for low cost, high
yield, rapid through put and short-cycle time manufacturing. We have developed
GaAs MESFET processes that we use to produce most of our products. By using ion
implant variations, we can optimize performance and yield, allowing us to
produce, for example, high-linearity, low-noise, receiver integrated circuits or
transmitter integrated circuits with high power and efficiency.

    We have also developed a GaAs PHEMT manufacturing process, which achieves
extremely high electron mobility. Devices manufactured using our PHEMT
manufacturing process have better sensitivity and bandwidth than conventional
MESFET devices and hence are an enabling technology that serves high bit rate
fiber optic systems. We have introduced devices for fiber optic communications
applications using our recently developed PHEMT manufacturing process.

    Fabricated wafers are shipped to contractors in Asia for assembly in
integrated circuit packages. Once assembled by the contractor, packaged
integrated circuits are shipped back to our Warren, New Jersey facility for
final testing. We believe that our flexible automated test systems are important
to our ability to manufacture high quality integrated circuits at a low cost. We
have devoted substantial capital over the last 18 months to increase our
capacity of automated testers, resulting in shortened product cycle times,
reduced test-costs and improved test reliability. See "Risk Factors--We may face
constraints on our manufacturing capacity which would limit our ability to
increase sales volumes," "--We may face constraints on our test capacity which
could result in manufacturing delays" and "--We depend on foreign semiconductor
assembly contractors and a loss of an assembly contractor could result in delays
or reductions in product shipment".

    Our design and manufacturing processes were certified as ISO 9001 compliant
in December 1993. Since then, we have maintained compliance with this standard.

RAW MATERIALS

    GaAs wafers, other raw materials, and equipment used in the production of
our integrated circuits are available from several suppliers. See "Risk
Factors--Sources for certain components,

                                       31
<PAGE>
materials and equipment are limited which could result in delays or reductions
in product shipments".

RESEARCH AND DEVELOPMENT

    We have made significant investments in our proprietary processes, including
product design, wafer fabrication and integrated circuit testing, which we
believe gives us a competitive advantage. To date, our research and development
efforts have focused on developing low cost, high volume production of GaAs
integrated circuit products for the telecommunication and cable television
industries. At July 4, 1999, we had approximately 80 engineers assigned
primarily to research and development.

    We have increased our research and development efforts in our broadband
communications applications, such as cable and broadcast and fiber optic, during
1999 and expect our wireless communications research and development efforts to
remain consistent with 1998 levels.

    The ability to simulate and model circuits is a critical technology for
analog integrated circuit design, especially at high frequencies. We have
developed a set of simulation tools and device models, which are custom-fit to
our process. Recognizing the importance of powerful electronic design automation
tools, in 1998 we formed a partnership with a leading manufacturer of radio
frequency/analog electronic design automation systems to develop and enhance
design tools to improve our research and development efficiency. The
partnership's primary objectives are to improve package modeling, design tool
training and design tool integration.

    We are also in the process of researching and developing other wafer
processing technologies. For our GaAs HBT technology we have formed both foundry
and technological partnerships. These agreements generally require us to share
our expertise and proprietary technology over a limited time period with our
partner in exchange for access to their expertise and proprietary technology. In
addition, we have the right to obtain foundry services on favorable terms. In
certain cases we may pay licensing fees, reimburse expenses and/or commit to
purchase a portion of our wafer needs from the other party. We plan to implement
this technology in our manufacturing facility by the first half of 2000. We have
recently hired a chief scientist specifically devoted to HBT technology and have
started HBT design runs with our foundry partner. We believe these actions will
position us to be the first-to-market with products based on six-inch GaAs HBT
technology.

    We believe there are opportunities to develop integrated circuits in silicon
or silicon germanium which would supplement our GaAs integrated circuits in
modules. Although GaAs provides performance advantages over silicon in
high-performance radio frequency integrated circuits, silicon is a more
cost-effective solution for the lower performance part of a system. Silicon
radio frequency chips are used by our customers in conjunction with our GaAs
chips to perform less complex radio frequency functions. As we seek to increase
our integrated circuit content in product applications, we are expanding our
product offerings to include low-end radio frequency integrated circuits
manufactured with silicon products. Further, we believe some of these silicon
integrated circuits may have significant market potential as stand-alone
integrated circuits. The recently established RF Standard Products Group at
ANADIGICS will be exploring the use of these technologies in the wireless
application. We currently do not intend to manufacture in either of these
technologies as we believe there will be adequate foundry capacity available.

COMPETITION

    Competition in all of the markets for our current products is intense and we
compete on the basis of performance, price and delivery. Competitors in the
wireless market are suppliers of discrete devices and integrated circuits. Our
competitors include Alpha, Conexant Systems, Fujitsu Compound Semiconductor,
Hitachi, Infineon Technologies (a subsidiary of Siemens AG), Matsushita Electric
Industrial, Motorola, RF Micro Devices, Royal Philips Electronics N.V., and
TriQuint Semiconductor.

                                       32
<PAGE>
    In the cable and broadcast television markets, our integrated circuits
compete primarily with manufacturers of discrete components and integrated
circuits. Our competitors include Fujitsu Compound Semiconductor, Infineon,
Maxim Integrated Products, Mitel Corporation, Mitsubishi Electric Corp., NEC
Corp. and Royal Philips Electronics.

    In the fiber optic market, we compete with other GaAs and silicon integrated
circuit manufacturers. Principal competitors in this market are Royal Philips
Electronics, TriQuint Semiconductor and Vitesse Semiconductor as well as some of
our customers who design and fabricate their own in-house solutions. In
particular, we expect to face increased competition in our fiber optic products
used in low-data-rate SONET fiber optic transmissions. See "Risk Factors--We
face intense competition which could result in a decrease of our products'
prices and sales."

    Many of our competitors have significantly greater financial, technical,
manufacturing and marketing resources than we have. Increased competition could
adversely affect our revenue and profitability by causing us to reduce prices or
by reducing demand for our products.

CUSTOMERS

    We receive most of our revenues from a few significant customers. Sales to
Ericsson, General Instrument and Qualcomm Personal Electronics accounted for
16%, 16% and 12%, respectively, of 1996 net sales, and 33%, 13% and 16%,
respectively, of 1997 net sales. Ericsson and General Instrument accounted for
34% and 17%, respectively, of 1998 net sales, and 40% and 21%, respectively, of
net sales during the six month period ended July 4, 1999. No other customer
accounted for greater than 10% of net sales during these periods. Substantially
all of our sales of wireless applications are to Ericsson.

EMPLOYEES

    At July 4, 1999, we had approximately 488 employees, none of whom was a
member of a labor union. We believe our labor relations to be good and have
never experienced a work stoppage.

PATENTS, LICENSES AND PROPRIETARY RIGHTS

    It is our practice to seek U.S. and foreign patent and copyright protection
on our products and developments where appropriate and to protect our valuable
technology under U.S. and foreign laws affording protection for trade secrets
and for semiconductor chip designs. We own seventeen U.S. patents and have six
pending U.S. patent applications and one pending foreign patent application
filed under the Patent Cooperation Treaty. The U.S. patents were issued between
1988 and 1999 and will expire between 2006 and 2016.

    We rely primarily upon trade secrets, technical know-how and other
unpatented proprietary information relating to our product development and
manufacturing activities. To protect our trade secrets, technical know-how and
other proprietary information, our employees are required to enter into
agreements providing for maintenance of confidentiality and the assignment of
rights to inventions made by them while in our employ. We also have entered into
non-disclosure agreements to protect our confidential information delivered to
third parties, in conjunction with possible corporate collaborations and for
other purposes.

ENVIRONMENTAL MATTERS

    Our operations are subject to many federal, state and local environmental
laws, regulations and ordinances that govern activities or operations that may
have adverse effects on human health or the environment. These laws, regulations
or ordinances may impose liability for the cost of remediating, and for certain
damages resulting from, sites of past releases of hazardous materials. We
believe that we currently conduct, and in the past have conducted, our
activities and operations in substantial compliance with applicable
environmental laws, and that costs arising from existing

                                       33
<PAGE>
environmental laws will not have a material adverse effect on our results of
operations. We cannot assure you, however, that the environmental laws will not
become more stringent in the future or that we will not incur significant costs
in the future in order to comply with these laws.

LEGAL MATTERS

    SHAREHOLDER LITIGATION

    In March and April 1998, seven lawsuits were filed against ANADIGICS and
various of our officers and directors in the United States District Court for
the District of New Jersey. The lawsuits are: ASSUNCAO v. ANADIGICS, INC., ET
AL., OFFICE AND PROFESSIONAL EMPLOYEES INTERNATIONAL UNION LOCAL 153 PENSION
FUND v. ANADIGICS, INC., ET AL., KOTLER v. ANADIGICS, INC., ET AL., GRAY v.
ANADIGICS, INC., ET AL., MIRPURI v. ANADIGICS, INC., ET AL., GRAYSON v.
ROSENZWEIG, ET AL., and MORGANTE v. ANADIGICS, INC., ET AL.

    Each complaint names as defendants one or more of the following directors
and officers of ANADIGICS: Ronald Rosenzweig, George Gilbert, Harry T. Rein,
John F. Lyons, Charles Huang, Javed Patel, Sheo Khetan and Robert Bayruns. The
complaints allege that ANADIGICS and certain of its officers and directors
violated the federal securities laws by making misstatements and/or omissions
during the period from August 1, 1997 through January 29, 1998 concerning our
performance and financial projections. The complaints also allege common law
fraud and/or negligent misrepresentation and seek unspecified damages. The seven
lawsuits have been consolidated into one class action action lawsuit captioned
IN RE ANADIGICS, INC. SECURITIES LITIGATION.

    In August 1998, a shareholders derivative lawsuit, captioned DEEGAN v.
ROSENZWEIG, ET AL., was filed in the United States District Court for the
District of New Jersey against ANADIGICS and the following of our officers and
directors: Charles Burton, Paul Bachow, Robert Bayruns, Ronald Rosenzweig,
George Gilbert, John Lyons, Harry Rein, Sheo Khetan, Javed Patel, Charles Huang
and Phillip Wallace. The complaint alleges claims based upon the above listed
lawsuits, and seeks damages, contribution, indemnification and equitable relief.

    On July 8, 1999, we and attorneys representing the plaintiffs in the
lawsuits described above entered into a memorandum of understanding setting
forth proposed settlement terms. Accordingly, we expect that all of the lawsuits
described above will be settled for a total payment of $11.75 million of which
approximately $5.3 million will be reimbursed by our insurance companies. The
proposed settlement is subject to various conditions, including the entering
into of a definitive settlement agreement and final court approval.

    PATENT LITIGATION AND CLAIMS

    In February 1999, The Lemelson Medical, Education and Research Foundation,
Limited Partnership filed a lawsuit against ANADIGICS and a number of other
companies in the United States District Court for the District of Arizona. The
lawsuit alleges that the defendants named have infringed upon patents held by
Lemelson. In addition, there is an unresolved notice from Rockwell International
Corporation asserting that we are infringing upon a patent on the processing of
semiconductor wafers. The patent will expire in March 2000. We intend to
vigorously defend against these allegations.

                                    GLOSSARY

PHEMT--Pseudomorphic High Electron Mobility Transistor.

    PHEMT is a type of transistor that can be manufactured in GaAs. PHEMT is a
    high performance design that uses similar processing to MESFET but a more
    expensive starting wafer material. PHEMT offers higher performance than
    silicon.

MESFET--Metal Semiconductor Field Effect Transistor.

    MESFET is a type of transistor that can be manufactured in GaAs. MESFET is a
    very cost effective design. MESFET offers higher performance than silicon.

HBT--Heterojunction Bipolar Transistor.

    HBT is a type of transistor that can be manufactured in GaAs. HBT uses a
    more expensive material than MESFET and PHEMT and requires additional
    processing steps but offers a smaller chip size. HBT offers higher
    performance than silicon.

GAAS--Gallium Arsenide.

    GaAs is a semiconductor material similar to silicon with certain unique
    properties, such as high frequency operation for microwave circuits and
    optical properties for fiber optic applications.

CDMA--Code Division Multiple Access.

    A United States digital wireless standard that increases capacity by coding
    voice messages and spreading information over many channels.

TDMA--Time Division Multiple Access.

    A United States digital wireless standard that increases capacity by placing
    three or more calls in the same channel separated by time.

GSM--Global System Mobile.

    The European digital cellular standard that is the most widely deployed
    digital standard in the world.

SDH--Synchronous Digital Hierarchy.

    The European fiber optic communications standard compiled by the
    International Telecommunications Union. Defines performance requirements for
    public switched telephone networks.

SONET--Synchronous Optical Network.

    The United States fiber optic communications standard compiled by Bellcore
    (now Telcordia). Defines performance requirements for public switched
    telephone networks.

GIGABIT ETHERNET--Gigabit Ethernet is a local area network transmission standard
    that provides a data rate of 1 billion bits per second (one gigabit),
    usually on optical fiber.

SENSITIVITY--The sensitivity of a device is a measure of its ability to detect a
    change in the input signal as reflected in a change in the output of the
    device.

RADIO FREQUENCY/MICROWAVE INTEGRATED CIRCUIT--Integrated circuit used in the
    radio section of a network or device to transmit, receive, or process a
    radio/microwave frequency communication signal.

BANDWIDTH--Bandwidth is a measure of the range of frequencies a communication
    signal occupies. In digital systems, bandwidth is data speed in bits per
    second. In analog systems, bandwidth is defined in terms of the difference
    between the highest-frequency signal component and the lowest-frequency
    signal component.

DWDM--Dense Wavelength Division Multiplexing.

    A fiber optic communications technology that allows broadband data
    transmission by simultaneously transmitting multiplex signals, carried in
    distinct wavelengths of light, over a single optical fiber.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF PRESENTATION

    The accompanying unaudited, condensed, consolidated financial statements
have been prepared in accordance with generally accepted accounting principles
for interim financial information and with the instructions to Form 10-Q and
Article 10 of Regulation S-X. Accordingly, they do not include all of the
information and footnotes required by generally accepted accounting principles
for complete financial statements. In the opinion of management, all adjustments
(consisting of normal recurring accruals) considered necessary for a fair
presentation have been included. Operating results for the six month period
ended July 4, 1999 are not necessarily indicative of the results that may be
expected for the year ending December 31, 1999.

    The condensed balance sheet at December 31, 1998 has been derived from the
audited financial statements at that date but does not include all the
information and footnotes required by generally accepted accounting principles
for complete financial statements.

    For further information, refer to the consolidated financial statements and
footnotes thereto included in the Company's Annual Report on Form 10-K for the
year ended December 31, 1998.

    The condensed, consolidated financial statements include the accounts of the
Company and its wholly owned subsidiaries, Broadcast and Wireless Investors,
Inc. and ANADIGICS Foreign Sales Corporation. All significant intercompany
accounts have been eliminated in consolidation.

5. LEGAL PROCEEDINGS

    In March and April 1998, seven proposed class action lawsuits (collectively
the "Class Action Lawsuits") were filed against the Company and certain of its
officers and directors in the United States District Court for the District of
New Jersey. The Complaints filed in the Class Action Lawsuits claim alleged
common law fraud and negligent misrepresentation. The Complaints alleged that,
as a result of certain material misstatements and omissions made by the Company
in connection with its business, the price of the Company's common stock was
artificially inflated during the proposed class periods (July 17, 1997 through
January 30, 1998).

    On December 20, 1998, the United States District Court for the District of
New Jersey consolidated the Class Action Lawsuits into one action, captioned In
re Anadigics, Inc. Securities Litigation, No. 98-CV-917 (the "Consolidated Class
Action Lawsuit"), and appointed Lead Plaintiffs and Lead Plaintiffs' Counsel.

    On or about August 3, 1998, a shareholder's derivative lawsuit ("Derivative
Lawsuit") was filed in the United States District Court for the District of New
Jersey against the Company (as nominal defendant) and certain of its officers
and directors. The Complaint in the Derivative Lawsuit alleged claims, which are
predicated upon the Class Action Lawsuits, seeking damages, contribution,
indemnification and equitable relief.

    On July 8, 1999, the Company and attorneys representing the plaintiffs in
the lawsuits described above entered into a memorandum of understanding setting
forth proposed settlement terms. Accordingly, we expect that all of the lawsuits
described above will be settled for a total payment of $11.75 million. In
connection with such settlement, the Company has entered into separate written
agreements with its insurance companies pursuant to which such insurance
companies will pay the Company an aggregate of $5.3 million no later than ten
days after final court approval of the settlement. The proposed settlement is
subject to various conditions including the entering into of a definitive
settlement agreement and final court approval.

6. SUBSEQUENT EVENT

    On July 22, 1999, the Company approved a public offering (the "Offering") of
an additional 3,000,000 shares of common stock (plus an additional 450,000
shares of common stock that may be issued upon exercise of an overallotment
option by the underwriters). The Company intends to use the net proceeds from
the offering for capital expenditures, working capital, and other general
corporate purposes. The Company may use all or a portion of the net proceeds to
acquire complementary businesses if the opportunity arises, however it currently
has no commitments or agreements with respect to any such transactions.

                         REPORT OF INDEPENDENT AUDITORS

The Board of Directors and Stockholders
ANADIGICS, Inc.

    We have audited the accompanying consolidated balance sheets of ANADIGICS,
Inc. as of December 31, 1997 and 1998, and 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, 1998. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements 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 financial statements referred to above present fairly,
in all material respects, the consolidated financial position of ANADIGICS, Inc.
as of December 31, 1997 and 1998, and the consolidated results of their
operations, comprehensive income and their cash flows for each of the three
years in the period ended December 31, 1998, in conformity with generally
accepted accounting principles.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    NATURE OF OPERATIONS AND BASIS OF PRESENTATION

    ANADIGICS, Inc. (the "Company") is a leading supplier of radio frequency
("RF") integrated circuit solutions for the communications markets. The
Company's products are used to receive and transmit signals in a variety of
broadband and wireless communications applications. The Company's efforts in the
broadband area are focused applications for cable television systems ("CATV")
and fiber optic communications systems. In the wireless area the Company's
efforts are directed towards applications in cellular telephone and personal
communication systems ("PCS"). The Company designs, develops and manufactures
its integrated circuits primarily using gallium arsenide ("GaAs") semiconductor
material. GaAs offers certain advantages in RF/microwave applications including
the integration of numerous RF/microwave functions which cannot be easily
integrated in silicon-based circuits. The Company's high frequency integrated
circuits can typically replace 30 to 100 discrete components, permitting
manufacturers of end products to reduce the size and weight of their products,
increase power efficiency, improve reliability, reduce manufacturing time and
cost and enhance system performance.

    The consolidated financial statements include the accounts of the Company
and its wholly owned subsidiary, ANADIGICS Foreign Sales Corporation. All
significant inter-company accounts and transactions have been eliminated in
consolidation.

    CONCENTRATION OF CREDIT RISK

    The Company grants trade credit to its customers, which are primarily
foreign manufacturers of wireless communication devices, cable and broadcast
television receivers and fiber optic communication devices. The Company performs
periodic credit evaluations of its customers and generally does not require
collateral. Accounts receivable from customers are denominated in U.S. dollars.
The Company has not experienced significant losses related to receivables from
individual customers.

    Approximately 45% of the Company's net sales in 1996 were to three
customers, accounting for 16%, 16%, and 12% of net sales. Approximately 62% of
the Company's net sales in 1997 were to three customers, accounting for 33%, 16%
and 13% of net sales. Approximately 51% of the Company's net sales in 1998 were
to two customers, accounting for 34% and 17% of net sales; accounts receivable
from these customers accounted for 64% of total accounts receivable at December
31, 1998. Net sales to individual customers who accounted for 10% or more of the
Company's total net sales and corresponding end application information are as
follows:

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    USE OF ESTIMATES

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

    REVENUE RECOGNITION

    Production revenue is recorded when products are shipped to customers.
Revenues under customer-funded research and development contracts, which are
recorded relative to the deliverables and other contractual obligations were
$3,193 in 1996, $1,566 in 1997, and $715 in 1998, and are included in net sales
on the consolidated statements of operations. The costs associated with the
customer-funded research and development contracts approximates the revenue
recorded and are included in cost of sales on the consolidated statements of
operations.

    WARRANTY COSTS

    The Company provides, by a current charge to income, an amount it estimates
will be needed to cover future warranty obligations for products sold during the
year. The accrued liability for warranty costs is included in Accrued
Liabilities in the consolidated balance sheet.

    COMPUTER SOFTWARE DEVELOPED OR OBTAINED FOR INTERNAL USE

    All direct internal and external costs incurred in connection with the
designing of software configuration and software interface, installing hardware
and testing systems are capitalized. All other costs associated with internal
use software are expensed when incurred. Amounts capitalized are amortized on a
straight-line basis over three years.

    PLANT AND EQUIPMENT

    Plant and equipment are stated at cost. Depreciation of plant and equipment
has been provided on the straight-line method over 3-5 years.

    The cost of equipment acquired under capital leases was $13,045 and $11,987
at December 31, 1997 and 1998, respectively, and accumulated amortization was
$11,941 and $11,639 at December 31, 1997 and 1998, respectively. Equipment
acquired under a capital lease is amortized over the useful life of the leased
equipment or the life of the lease, whichever is shorter.

    INCOME TAXES

    Deferred income taxes reflect the net effects of temporary differences
between the carrying amount of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes.

           (DOLLARS IN THOUSANDS, EXCEPT SHARE AND PER SHARE AMOUNTS)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    RESEARCH AND DEVELOPMENT COSTS

    The Company charges all research and development costs associated with the
development of new products to expense when incurred. Engineering and design
costs related to customer-funded research and development contracts are
classified as cost of sales.

    CASH EQUIVALENTS

    The Company considers as cash equivalents all highly liquid marketable
securities with an original maturity of three months or less.

    MARKETABLE SECURITIES

    Available for sale securities are stated at fair value, with the unrealized
gains and losses, net of tax, reported in other comprehensive income or loss.
The cost of securities sold is based upon the specific identification method.
The amortized cost of debt securities is adjusted for amortization of premium
and accretion of discounts to maturity. Such amortization, realized gains and
losses, interest and dividends are included in interest income.

    STOCK BASED COMPENSATION

    As permitted by FASB Statement No. 123, "Accounting for Stock-Based
Compensation" (FASB 123), the Company has elected to follow Accounting Principal
Board Opinion No. 25, "Accounting for Stock Issued to Employees" (APB 25) and
related interpretations in accounting for its employee stock option plans. Under
APB 25, no compensation expense is recognized at the time of option grant
because the exercise price of the Company's employee stock option equals the
fair market value of the underlying common stock on the date of grant.

    IMPAIRMENT OF LONG-LIVED ASSETS

    The Company records impairment losses on long-lived assets including
capitalized software costs used in operations or expected to be disposed when
events and circumstances indicate that the undiscounted cash flows estimated to
be generated by these assets are less than the carrying amounts of those assets
(See Note 12.-RESTRUCTURING CHARGES)

    EARNINGS PER SHARE

    Basic and diluted earnings per share are calculated in accordance with FASB
Statement No. 128, "Earnings Per Share". All earnings per share amounts for all
periods have been presented, and where appropriate, restated to conform to the
requirements of FASB 128.

    COMPREHENSIVE INCOME

    Effective January 1, 1998, the Company adopted FASB Statement No. 130,
Reporting Comprehensive Income ("FASB 130"). FASB 130 establishes new rules for
the reporting and display of comprehensive income (or loss) and its components
in the financial statements. The adoption of FASB 130 had no effect on the
Company's financial position or results of operations.

           (DOLLARS IN THOUSANDS, EXCEPT SHARE AND PER SHARE AMOUNTS)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
Statement 130 requires unrealized gains (losses) on the Company's
available-for-sale securities, which previously were reported in stockholders'
equity, to be included in other comprehensive income and the disclosure of total
comprehensive income.

    RECLASSIFICATIONS

    Certain amounts as of December 31, 1997 have been reclassified to conform
with the December 31, 1998 presentation.

    IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS

    In June 1998, the FASB issued Statement No. 133, Accounting for Derivative
Instruments and Hedging Activities. The Company expects to adopt the new
Statement effective January 1, 2000. The Statement will require the Company to
recognize all derivatives on the balance sheet at fair value. The Company does
not anticipate that the adoption of this Statement will have a significant
effect on its results of operations or financial position.

7. DISCLOSURES ABOUT SEGMENTS OF AN ENTERPRISE AND RELATED INFORMATION

    Effective January 1, 1998, the Company adopted Statement No. 131,
Disclosures About Segments of an Enterprise and Related Information ("FASB
131"). FASB 131 establishes standards for reporting information about operating
segments in annual financial statements and requires that those enterprises
report selected information about operating segments in interim financial
reports to shareholders. It also establishes standards for related disclosures
about products and services, geographic areas, and major customers.

    The Company believes it operates in one segment. Since all of the Company's
integrated circuits are manufactured using the same manufacturing facilities
located in the same geographic area, all operating expenses and assets of the
Company are combined and reviewed by the chief operating decision maker on an
enterprise-wide basis, resulting in no additional discrete financial information
or reportable segment information.

10. LONG-TERM DEBT, CREDIT FACILITY AND INTEREST RATE SWAP AGREEMENT

    The Company has a secured $20,000 term loan facility under which $5,000 was
drawn down on December 30, 1998 and was outstanding as of December 31, 1998. The
$5,000 consists of a term-loan that requires equal principal repayments of $250
due quarterly through December 31, 2003, plus interest.

    Interest on the credit facility is calculated at LIBOR plus 1.75%. The LIBOR
rate was 5.34% at December 31, 1998. The Company enters into interest rate swap
agreements to manage its exposure to interest rate movements by effectively
converting its debt from variable to fixed rates. Maturity dates of the interest
rate swap agreements will generally match those of the underlying debt or
financial arrangements. As of December 31, 1998, the Company has entered into
one interest rate swap with a maturity of five years and involved the exchange
of variable rate payments for fixed rate payments without the exchange of the
underlying principal amounts. In accordance with the terms of the swap
agreement, the Company pays 7.09% interest and receives LIBOR plus 1.75%
calculated on the notional amount. The notional amount of the interest rate swap
was $5,000 at December 31, 1998. The Company concluded that the swap effectively
changed the variable interest rate characteristics to a fixed rate for which the
present value of the cash flows are approximately the same, and as a result,
there is no adjustment to mark the swap to market. Cash flows associated with
the financial instrument are classified consistent with the cash flows from the
transactions being hedged.

    The remaining $15,000 under the term loan facility provides for interest at
the bank's base rate minus 25 basis points or, at the Company's discretion,
other market-based rates. The Company has the option to swap floating rate for
fixed rate loans at the time of drawdown. The drawdown period expires on July 1,
1999. Any drawdowns may be paid over a term of up to sixty months. Its
availability is subject to a number of financial covenants. Under this facility,
the payment of dividends, among other things, requires approval by the bank.
Substantially all assets of the Company are pledged as security for the
repayment of amounts drawn under this credit facility. On a quarterly basis, the
Company pays an annual commitment fee equal to 0.125% of the daily unused line
of credit.

11. EMPLOYEE BENEFIT PLANS

    In 1995, the Company adopted an employee stock purchase plan ("ESP
Plan")under Section 423 of the Internal Revenue Code. All full-time employees of
the Company and part-time employees, as defined in the ESP Plan, are eligible to
participate in the ESP Plan. An aggregate of 562,500 shares of common stock are
reserved for offering under the ESP Plan. Offerings are made at the commencement
of each calendar year and must be purchased by the end of that calendar year. In
1997, 44,515 shares of common stock were purchased at a price of $21.99 per
share, as determined by the ESP Plan, which approximates fair value. During
1998, 43,627 shares of common stock were purchased at a price of $9.75 per
share, as determined by the ESP Plan, which approximates fair value.

    Certain executives and key employees have been granted options to purchase
shares of common stock under stock option plans adopted in 1994, 1995 and 1997.
An aggregate of 326,087, 2,775,000 and 1,200,000 shares of common stock were
reserved for issuance under the 1994 Long-Term Incentive Share and Award Plan,
the 1995 Long-Term Incentive Share Award Plan and the 1997 Long-Term Incentive
and Share Award Plan for Employees (the "Plans"), respectively. The Plans
provide for the granting of stock options, stock appreciation rights, restricted
shares, or other share based awards to eligible employees and directors, as
defined in the Plans. Options granted under the Plans become exercisable in
varying amounts over periods of up to three years.

    FASB 123 requires pro forma information regarding net income and earnings
per share as if the Company has accounted for its employee stock options and
warrants granted subsequent to December 31, 1994 and shares of common stock
purchased by employees in connection with the ESP Plan ("equity awards") under
the fair value method of FASB 123. The fair value of these equity awards was
estimated at the date of grant using a Black-Scholes option pricing model with
the following weighted average assumptions for 1996, 1997 and 1998,
respectively: risk-free interest rate of 5.17%, 5.90%, and 4.50%; expected
volatility of 0.50, 0.50, and 0.60; expected option life of one year from
vesting and an expected dividend yield of 0.0%.

    For purposes of pro forma disclosures, the estimated fair value of the
equity awards is amortized to expense over the options' vesting period. The
Company's pro forma information is as follows:

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

Pro forma basic earnings (loss) per share.....................................  $    0.85  $    0.82  $    (0.89)
</TABLE>

    Because FASB 123 is applicable only to equity awards granted subsequent to
December 31, 1994, its pro forma effect was not fully reflected until 1997.

12. RESTRUCTURING CHARGES

    The Company recorded restructuring charges totaling $7,126 during 1998. The
restructuring charges consisted of writedowns of impaired long-lived assets of
$4,510, reductions in work force of $1,616 and wafer fabrication facility
shutdown and removal costs of $1,000 which are expected to be completed in 1999.
In connection with the impairment evaluation, the Company determined that
certain other equipment related to the conversion of the new wafer fabrication
facility has shorter depreciable lives. Accordingly, the Company accelerated
depreciation on these assets during the year for which the effect on net loss
was approximately $(1,517) or $(0.10) per share. These assets, which now have
revised estimated useful lives of nine months, had original estimated useful
lives of five to twenty years.

    WRITEDOWNS OF IMPAIRED ASSETS.  The Company evaluated the on-going value of
certain assets. Based upon this evaluation, the Company plans to dispose of
certain assets during the next twelve months with a carrying amount of $4,635
and estimated the sales value, net of related costs to sell, at $125. The
estimated sales value was based on quoted market prices or on the best
information available in the circumstances. In most instances, there was no
market for the impaired asset and therefore the fair value was zero. As a
result, the Company recorded an impairment loss of $4,510, which consisted of
the following items:

    The effect of suspending depreciation on these assets was approximately $220
during 1998.

    REDUCTIONS IN FORCE.  The Company recorded charges of $1,100 during the
first quarter of 1998 and $516 during the fourth quarter of 1998 associated with
reductions in its workforce. The workforce reduction charges primarily consisted
of severance pay, extended medical coverage, and outplacement service costs for
approximately 165 employees primarily involved in the Company's production
operations. Approximately $1,049 of severance pay, extended medical coverage,
and outplacement service costs were paid through December 31, 1998 for the
termination of 120 employees. The remaining liability of $567 is expected to be
paid during the first half of 1999.

    FACILITY SHUTDOWN AND REMOVAL COSTS.  The Company recorded charges of $1,000
associated with the shutdown and removal of its existing wafer fabrication
facility, which is expected to be completed in 1999.

14. COMMITMENTS AND CONTINGENCIES

    In March and April 1998, there were filed against the Company and certain of
its officers and directors in the United States District Court for the District
of New Jersey seven proposed class action lawsuits (collectively, the "Class
Action Lawsuits"), captioned Assuncao v. Anadigics, Inc., et al., No. 98-917;
Office and Professional Employees International Union Local 153 Pension Fund v.
Anadigics, Inc., et al., No. 98-919; Kotler v. Anadigics, Inc., et al., No.
98-923; Gray v. Anadigics, Inc., et al., No. 98-1337; Mirpuri v. Anadigics,
Inc., et al., No. 98-1811; Grayson v. Rosenzweig, et al., No. 98-1688; and
Morgante v. Anadigics, Inc., et al., No. 98-2024. The Complaints filed in the

the Company: Ronald Rosenzweig, George Gilbert, Harry T. Rein, John F. Lyons,
Charles Huang, Javed Patel, Sheo Khetan and Robert Bayruns) seek unspecified
damages in connection with claims under Sections 10(b) (and Rule 10b-5
promulgated thereunder) and 20(a) of the Securities Exchange Act of 1934 and, as
set forth in the Union Local 153, Kotler, Gray and Mirpuri Complaints, claims
alleging common law fraud and negligent misrepresentation. The Complaints allege
that, as a result of certain material misstatements and omissions made by the
Company in connection with its business, the price of the Company's common stock
was artificially inflated during the proposed class periods. The longest
proposed class period alleged by the plaintiffs in the Class Action Lawsuits is
the period from July 17, 1997 through January 30, 1998. On December 20, 1998,
the United States District Court for the District of New Jersey entered an Order
consolidating the Class Action Lawsuits into one action, captioned In re
Anadigics, Inc. Securities Litigation, No. 98-CV-917 (the "Consolidated Class
Action Lawsuit"), and appointing Lead Plaintiffs and Lead Plaintiffs' Counsel.
The parties to the Consolidated Class Action Lawsuit have jointly requested the
Court to extend to April 5, 1999 the deadline by which plaintiffs must file
their Amended Consolidated Complaint. The Company is unable at this time to
assess the probable outcome of the Consolidated Class Action Lawsuit or the
materiality of the risk of loss in connection therewith (given that none of the
original Complaints had alleged damages with any particularity and the Amended
Consolidated Complaint has not yet been served).

    On or about August 3, 1998, a shareholders derivative lawsuit, captioned
Deegan v. Rosenzweig, et al., No. 98-CV-3640 (the "Derivative Lawsuit"), was
filed in the United States District Court for the District of New Jersey against
the Company (as nominal defendant) and the following officers and directors
thereof: Charles Burton, Paul Bachow, Robert Bayruns, Ronald Rosenzweig, George
Gilbert, John Lyons, Harry Rein, Sheo Khetan, Javed Patel, Charles Huang and
Phillip Wallace. The Complaint in the Derivative Lawsuit alleges claims, which
are predicated upon the Class Action Lawsuits, seeking damages, contribution,
indemnification and equitable relief. On October 28, 1998, the United States
District Court for the District of New Jersey stayed the Derivative Lawsuit
pending the earlier of (1) the disposition of any motion to dismiss the
Complaint (or any Consolidated Amended Complaint) in the Class Action Lawsuits
or (2) the commencement of discovery in the Class Action Lawsuits. As a result,
on October 29, 1998, the Court administratively dismissed the Derivative Lawsuit
without prejudice. The Company is unable at this time to assess the probable
outcome of the Derivative Lawsuit or the materiality of the risk of loss in
connection therewith (given that the original Complaint did not allege damages
with any particularity and no operative pleading presently exists).

    The Company is also involved in other threatened and pending legal
proceedings arising in the course of the Company's business. The adverse outcome
of any of these other legal proceedings is not expected to have a material
adverse effect on the results of operations or financial condition of the
Company.

    At December 31, 1998, the Company had committed to purchase approximately
$10,000 of equipment and furniture, and leasehold improvements during 1999.

    If the underwriters sell more shares than the total number set forth in the
table above, the underwriters have an option to buy up to an additional 450,000
shares from ANADIGICS to cover such sales. They may exercise that option for 30
days after the date of this prospectus. If any shares are purchased pursuant to
this option, the underwriters will severally purchase shares in approximately
the same proportion as shown in the table above.

    The following table shows the per share and total underwriting discounts and
commissions to be paid to the underwriters by ANADIGICS. These amounts are shown
assuming both no exercise and full exercise of the underwriters' option to
purchase additional shares.

    Shares sold by the underwriters to the public will initially be offered at
the initial price to public set forth on the cover of this prospectus. Any
shares sold by the underwriters to securities dealers may be sold at a discount
of up to $      per share from the initial price to public. Any such securities
dealers may resell any shares purchased from the underwriters to certain other
brokers or dealers at a discount of up to $      per share from the initial
price to public. If all the shares are not sold at the initial price to public,
the representatives may change the offering price and the other selling terms.

    ANADIGICS and its directors and executive officers have agreed with the
underwriters not to dispose of or hedge any of their common stock or securities
convertible into or exchangeable for shares of common stock during the period
from the date of this prospectus continuing through the date 90 days after the
date of this prospectus, except with the prior written consent of the
representatives of the underwriters. This agreement does not apply to any
existing employee benefit plans.

    In connection with the offering, the underwriters may purchase and sell
shares of common stock in the open market. These transactions may include short
sales, stabilizing transactions and purchases to cover positions created by
short sales. Short sales involve the sale by the underwriters of a greater
number of shares than they are required to purchase in the offering.

                                      U-1

Stabilizing transactions consist of certain bids or purchases made for the
purpose of preventing or retarding a decline in the market price of the common
stock while the offering is in progress.

    The underwriters also may impose a penalty bid. This occurs when a
particular underwriter repays to the underwriters a portion of the underwriting
discount received by it because the representatives of the underwriters have
purchased shares sold by or for the account of the underwriter in stabilizing or
short covering transactions.

    These activities by the underwriters may stabilize, maintain or otherwise
affect the market price of the common stock. As a result, the price of the
common stock may be higher than the price that otherwise might exist in the open
market. If these activities are commenced, they may be discontinued by the
underwriters at any time. These transactions may be effected on the Nasdaq
National Market, in the over-the-counter market or otherwise.

    ANADIGICS estimates that its share of the total expenses of the offering,
excluding underwriting discounts and commissions, will be approximately
$501,836.

    ANADIGICS has agreed to indemnify the several underwriters against certain
liabilities, including liabilities under the Securities Act of 1933, as amended.

    The underwriters and their affiliates have in the past provided, and may in
the future from time to time provide, investment banking services to ANADIGICS,
for which they may receive customary fees.
