    TriQuint Semiconductor, Inc. ("TriQuint" or the "Company") designs,
develops, manufactures and markets a broad range of high performance analog and
mixed signal integrated circuits for the communications markets. The Company
utilizes its proprietary gallium arsenide ("GaAs") technology to enable its
products to overcome the performance barriers of silicon devices in a variety of
applications. The Company sells its products on a worldwide basis and its end
user customers include Alcatel, Cellnet Data Systems, Ericsson, Hughes, Lucent
Technologies, Motorola, Nokia, Northern Telecom, Qualcomm and Raytheon.
 
    On January 13, 1998, the Company acquired substantially all of the assets of
the Monolithic Microwave Integrated Circuit ("MMIC") operations of the former
Texas Instruments' Defense Systems & Electronics Group from Raytheon TI Systems,
Inc. ("RTIS"), a Delaware corporation and a wholly owned subsidiary of Raytheon
Company ("Raytheon"). The MMIC operations include the GaAs foundry and MMIC
business of the R/F Microwave Business Unit that RTIS acquired on July 11, 1997
from Texas Instruments Incorporated ("TI") which MMIC business includes without
limitation, TI's GaAs Operations Group, TI's Microwave GaAs Products Business
Unit, the MMIC component of TI's Microwave GaAs Products Business Unit, the MMIC
component of TI's Microwave Integrated Circuits Center of Excellence and the
MMIC research and development component of TI's Systems Component Research
Laboratory (collectively, "Millimeter Wave Communications").
 
INDUSTRY BACKGROUND
 
    Market demands for higher levels of performance in electronic systems have
produced an increasing number of varied, complex applications. The increased
capabilities of these new systems, in turn, are spawning new markets and a
further proliferation of new, sophisticated applications. Many of these new
applications have emerged in the wireless communications, telecommunications,
computing and aerospace industries.
 
    The wireless communications industry is experiencing rapid growth with the
advent of new applications such as digital cellular telephones, personal
communication systems ("PCS"), pagers, handheld navigation products based on the
global positioning satellite ("GPS") standard, satellite communications such as
Direct Broadcast Satellite ("DBS"), wireless local area networks ("WLANs"),
wireless data transmission systems such as Cellular Digital Packet Data ("CDPD")
modems and wireless cable television. In addition, many of these new
applications require battery powered portability. The proliferation of some of
these new applications has led to increased communication traffic resulting in
congestion of the historically assigned frequency bands. As a consequence,
wireless communications are moving to higher, less congested frequency bands.
The Company believes the increasing demand for wireless communications at higher
frequencies, will lead to entirely new high volume applications.
 
                                       3
<PAGE>
    The telecommunications industry is encountering increasing demand for higher
transmission rates and increased capacity to accommodate the growth of
traditional voice traffic and higher levels of data traffic arising from
widely-used applications such as facsimile communications, computer networking
and online and Internet services. Today's advanced telecommunications systems
employ high speed switching networks and fiber optic cable operating in
accordance with high frequency standards such as synchronous optical network
("SONET"), Synchronous Digital Hierarchy ("SDH"), integrated services digital
network ("ISDN") and the asynchronous transfer mode ("ATM") standard. For
example, high performance SONET telecommunications systems can operate at
frequencies of 2.48 Gbits/sec or higher. The advent of video communications and
multimedia (combinations of voice, video and data) are placing further demands
on these systems for even higher data transmission rates.
 
    In the data communications industry, data processing speeds have increased
rapidly, bringing enormous computing power to individual users. The demand to
share data and peripheral equiqment among these users has led to the widespread
use of networking systems operating at increasing speeds. Today's advanced data
communication systems, based on standards such as Fibre Channel and Gigabit
Ethernet as well as proprietary links are used to transmit data at rates up to
2.5 Gbits/sec.
 
    The microwave and millimeter wave communications industry utilizes advanced
GaAs MMIC products for aerospace, defense and commercial applications. Aerospace
and defense applications include high power amplifiers, low noise amplifiers,
switches and attenuators for use in a variety of advanced requirements such as
active array radar, missiles, electronic warfare systems and space
communications systems. Commercial applications for products and services in
this frequency range include wireless telephone applications, optical fiber
links and switching networks, Local Multipoint Distribution System (LMDS)
systems, phased-array radar and satellite earthstation transmitters.
 
    To address the market demands for higher performance, electronic system
manufacturers have relied heavily on advances in semiconductor technology. In
recent years, the predominant semiconductor technologies used in advance
electronic systems have been silicon-based complementary metal oxide
semiconductor ("CMOS"), bipolar complementary metal oxide semiconductor
("BiCMOS") and emitter coupled logic ("ECL") process technologies. However, the
newest generation of high performance electronic systems requires further
advances in semiconductor performance. One way to improve performance is to
combine analog and digital circuitry on the same device. This combination, known
as mixed signal technology, can provide higher levels of integration (smaller
size and increased functionality), reduced power consumption and higher
operating frequencies. Notwithstanding the benefits of mixed signal technology,
the performance requirements of certain critical system functions generally
cannot be achieved using silicon-based components. As a result, system
manufacturers are seeking semiconductor products which can overcome the
performance limitations of silicon devices in a variety of applications.
 
    GaAs semiconductor technology has emerged as an effective alternative or
complement to silicon solutions in many high performance applications. GaAs has
inherent physical properties which allow its electrons to move up to five times
faster than those of silicon. This higher electron mobility permits the
manufacture of GaAs integrated circuits which operate at much higher speeds than
silicon devices, or operate at the same speeds with lower power consumption. The
process technologies utilized in GaAs semiconductor fabrication include metal
semiconductor field effect transistor ("MESFET"), pseudomorphic high electron
mobility transistor ("PHEMT"), heterojunction bipolar transistor ("HBT") and
heterostructure field effect transistor ("HFET"). In many new applications, GaAs
integrated circuits enable high performance systems to process data more
quickly, increasing system operating rates.
 
    In addition to enabling high performance systems to process data more
quickly, the use of GaAs integrated circuits can reduce system power
requirements, which is particularly important in battery powered portable
applications. The high performance characteristics of GaAs, combined with the
system requirements of the communications industry, have led to the use of GaAs
components in high volumes to complement silicon devices in a wide range of
commercial and aerospace systems.
 
                                       4
<PAGE>
    The Company believes that the continuation and acceleration of these trends
will result in increasing demand for GaAs integrated circuits, thereby creating
substantial opportunities for market-focused manufacturers who can provide a
broad range of cost effective GaAs integrated circuits in high volume.
 
MARKETS AND CUSTOMERS
 
    TriQuint has focused on commercial and aerospace applications in the
wireless communications, telecommunications, data communications and millimeter
wave communications market areas, which can benefit significantly from the
performance of GaAs and the Company's analog and mixed signal design expertise.
 
WIRELESS COMMUNICATIONS
 
    GaAs design and manufacturing technologies are being applied to commercial
communications in satellites, satellite receivers for TV broadcast, wireless
transceivers for data networks, handheld navigation systems based on the GPS
system, wireless LANs, cellular and PCS telephones.
 
    Frequency bands are allocated to the various wireless communications
applications by government regulatory bodies throughout the world. The
allocation is based, among other factors, upon the availability of unallocated
frequency bands and the ability of equipment to operate effectively in these
bands. As the lower frequency bands become fully allocated and congested, and
the volume and rate of communications increases, the trend is toward the
allocation and use of higher frequency bands. A major example is the U.S.
government's auction of PCS licenses. PCS systems operate at approximately twice
the frequency of conventional cellular systems. The speed of GaAs technology
makes it well-suited for applications at these higher frequencies.
 
    The superior ability of GaAs to operate at higher frequencies also makes it
well suited for use in defense applications. In addition, other key performance
advantages of GaAs over silicon in key wireless communications system functions
for both commercial and defense applications are improved signal reception,
better signal processing in congested bands and greater power efficiency for
longer battery life in portable applications.
 
TELECOMMUNICATIONS
 
    GaAs technologies are well suited for the growing markets and applications
which require the transmission or manipulation of large amounts of information
at high speeds with high data integrity. These applications, which typically
require customer specific solutions and include digital, analog and mixed signal
functions, are found primarily in the telecommunications industry, but also span
other industries such as instrumentation, aerospace and defense. For many of
these applications, the Company's products provide better price/performance
value than silicon. The intrinsic electrical properties of GaAs result in higher
speed, lower noise and less power consumption compared to silicon.
 
    The Company believes that the increasing use of fiber optic cable in
telecommunications and data communications systems has created a significant
growth opportunity for the Company's GaAs products. Because data transmission
rates in fiber optic cable can be many times greater than those of copper line,
a single fiber line can cost-effectively replace multiple copper lines. In order
to take advantage of the potential cost advantages of fiber optic
communications, information must be transmitted at higher rates generally
achievable only through the use of GaAs products such as those manufactured by
TriQuint.
 
    The telecommunication industry has established a series of standards, most
notably SONET, ISDN and ATM, which define transmission rates, protocols, signal
quality and reliability. GaAs based products address the performance
requirements of these standards, as well as higher speed communication links
(2.48 Gbits/sec and above).
 
                                       5
<PAGE>
DATA COMMUNICATIONS
 
    Data communications equipment is typically used to interconnect mainframe
computers, clients and servers, workstations, disk storage arrays and other
peripheral devices. Other applications, which require transmission of large
amounts of data at high speed include multimedia computing, supercomputing,
multiprocessor systems, interactive computer aided design/computer aided
manufacturing ("CAD/CAM"), medical imaging and high speed, high resolution
printing. As new applications requiring higher volume data transfer have
proliferated, and as microprocessor speeds have increased, a critical bottleneck
has developed in these communications links. The computation speed of today's
microprocessors is 10 to 100 times faster than currently available
communications equipment based on communications standards such as Ethernet and
Small Computer System Interface ("SCSI"). A solution to this problem is the use
of high speed serial data transmission by means of coaxial or fiber optic cable
in combination with the Company's mixed signal transmitting and receiving
devices. For example, leading computer manufacturers have acknowledged the need
for high speed serial data communications links by supporting the Fibre Channel
standard which can operate up to 1.25 Gbits/sec. TriQuint's products, using the
Company's mixed signal technology, enable high speed data transmission with high
data integrity.
 
MILLIMETER WAVE COMMUNICATIONS
 
    A broad array of customers and applications are served by the Company's
Millimeter Wave Communications operation. In aerospace applications, the
Company's history of involvement in the federal government's DARPA-based MIMIC
program has led to the development of MMIC products for phased-array radar
antenna modules. This advanced antenna/system technology finds application in
military aircraft, ships and spacecraft. It is also emerging as a key technology
in next-generation commercial spacecraft and mobile earth station platforms.
 
    Two important commercial applications served by the Company in this area are
point-to-point and point-to-multipoint digital radio markets. The point-to-point
radio market is driven by expansion of the wireless telephone market, as these
radios serve as the infrastructure to link the various remote towers to the
switching centers. The point-to-multipoint radio market is being driven by both
the LMDS auctions by the FCC for wireless distribution of phone, video and
two-way data services and the growing demand for high-speed wireless networks
not based on expensive or fixed-location fiber optic cable systems. The
Company's products are enabling radio system suppliers to greatly reduce
microwave and millimeter wave module costs by increasing the amount of circuitry
integrated on GaAs chips.
 
CUSTOMERS
 
    The Company has a broad customer base of leading systems manufacturers and
shipped products or provided manufacturing services directly to approximately
265 end user customers and distributors in 1998. The Company's largest customers
include Nokia and Raytheon TI Systems, which accounted for approximately 12.0%
and 11.7%, respectively, of the Company's total revenues in 1998. In 1997,
Northern Telecom accounted for approximately 12.0% of the Company's total
revenues. No other customer of the Company accounted for greater than 10% of
total revenues during these periods. If the Company were to lose any major
customer or if sales were to otherwise decrease, the Company's operating results
would be adversely affected.
 
    The markets in which the Company's customers compete are characterized by
rapidly changing technology, evolving industry standards and continuous
improvements in products and services. If technologies or standards supported by
the Company's or its customers' products become obsolete or fail to gain
widespread commercial acceptance, the Company's business may be materially
adversely affected.

PRODUCTS
 
    The Company's broad range of standard and customer-specific integrated
circuits, combined with its manufacturing and design services, allow customers
to select the specific integrated circuit solution which best fulfills their
technical and time-to-market requirements.
 
STANDARD PRODUCTS
 
    TriQuint offers families of standard products for each of its target
markets.
 
    WIRELESS COMMUNICATIONS.  The Company's standard products for this varied
market are used as building blocks for multi-purpose applications in radio
frequency ("RF") and microwave systems. These systems include personal
communications networks, cellular telephones, satellite communications and
navigation systems and wireless computer networks. TriQuint's wireless
communications standard products leverage the advantages of the Company's
proprietary GaAs technology by addressing the needs of system designers for low
noise, power efficient amplification, low loss switching and efficient and
accurate frequency conversion.
 
    TELECOMMUNICATIONS  While most of the Company's telecommunications products
are customer-specific, the Company also offers standard telecommunications
products, such as SONET and SDH multiplexers and demultiplexers to provide low
bit-error-rate performance in standard transmission applications and SONET/SDH
compatible transceivers that support clock and data recovery and ATM framing, as
well as high performance crosspoint switches.
 
    DATA COMMUNICATIONS  For this market, TriQuint offers families of standard
products which are targeted at high speed data communication applications.
 
    MILLIMETER WAVE COMMUNICATIONS  The Company offers a wide variety of
standard MMIC and discrete devices covering the DC to 45 Ghz frequency range.
The devices are adapted for both general purpose and application-specific signal
amplification or control purposes.
 
CUSTOMER-SPECIFIC PRODUCTS AND SERVICES
 
    TriQuint offers its customers a variety of product options and services for
the development of customer-specific products. Services offered by the Company
include design, wafer fabrication, test engineering, package engineering,
assembly and test. Customer-specific products and services generally provide
revenue at two stages: first when the design is developed and engineered, and
second when TriQuint manufactures the device. The Company focuses the
development of its customer specific-products on its target markets in
applications involving volume production requirements. As is typical in the
semiconductor industry, customer-specific products are developed for specific
applications. As a result, the Company expects to generate production revenues
only from those customer-specific products that are subsequently produced in
high volume.
 
    Customer-specific designs are generally implemented by one of two methods.
Under the first method, the customer supplies the Company with detailed
performance specifications and TriQuint performs the complete design,
development and subsequent manufacturing of the integrated circuits. These
designs are generated using either the Company's in-house design engineering
group or independent third-party design organizations qualified by the Company.
Under the second method, TriQuint supplies circuit design and process rules to
its customer and the customer's internal engineering staff designs products
which TriQuint then manufactures.
 
    A substantial portion of the Company's products are designed to address the
needs of individual customers. Frequent product introductions by systems
manufacturers make the Company's future success dependent on its ability to
select customer-specific development projects which will result in sufficient
production volume to enable the Company to achieve manufacturing efficiencies.
Because customer-
 
                                       7
<PAGE>
specific products are developed for unique applications, the Company expects
that some of its current and future customer-specific products may never be
produced in high volume. In addition, in the event of significant delays in
completing designs or the Company's failure to obtain development contracts from
customers whose systems achieve and sustain commercial market success, the
Company's results of operations could be materially adversely affected.
 
DESIGN AND PROCESS TECHNOLOGY
 
    In order to develop and introduce new products rapidly and cost-effectively
which address the needs of its target markets, the Company has made substantial
investments in building its capabilities in digital, analog and mixed signal
circuit design. The Company has developed an extensive library of digital and
analog cells and associated software tools and databases which it uses to
facilitate the design of its integrated circuits. The Company has also developed
and documented process and design rules which allow customers to design
proprietary circuits themselves. Mixed signal products, which generally involve
varied and complex functions operating at high frequencies, generally present
design and testing challenges. The Company believes that its extensive cell
library, optimized mixed signal process technology and design and test
engineering expertise in high performance mixed signal integrated circuits
address these challenges and provide a significant competitive advantage.
 
    TriQuint's manufacturing strategy is primarily to use high volume process
technologies which enables it to provide cost-effective solutions for its
customers. The Company's advanced wafer manufacturing process emphasizes
stability, uniformity and repeatability. Unlike its GaAs competitors who have
typically concentrated on either digital or analog products, TriQuint has
intentionally pursued process technologies that are cost-effective for digital,
analog and mixed signal applications. As a result of the ability to primarily
utilize core processes in the manufacture of its products, the Company is able
to enjoy the cost advantages associated with standard high volume semiconductor
manufacturing practices. The core process technology in the Company's Oregon
wafer fabrication operation employs all implanted structures, 4 micron metal
pitch and 0.5 to 0.7 micron geometries, involves 10 to 16 mask steps, has a
cutoff frequency of up to 21 GHz and is scalable. This scalability facilitates
further cost reduction and performance improvement. The process technology
employed in the Company's Texas wafer fabrication operation includes five
advanced performance production processes: 0.5 micron gate length MesFET for
amplifier applications; 0.25 and 0.5 micron gate length pHEMT for high power and
high frequency applications; HBT for high voltage, high linearity, and high
power density; 0.5 micron gate length HFET for high voltage, high power
amplifiers and switches; and VPIN for signal control devices such as switches,
limiters and attenuators.
 
    The Company applies the technological advances within the silicon and
related support industries to its design and manufacturing processes. TriQuint
utilizes popular CAD and process control tools and test equipment. The Company
primarily uses standard silicon industry packages and subcontracts its product
assembly operations.
 
MANUFACTURING
 
    The Company's Oregon wafer manufacturing facility is located at its leased
headquarters location in Hillsboro. The Company moved its executive,
administrative, test and technical offices to a new 124,000 square foot leased
facility in Hillsboro, Oregon in the first quarter of 1997. Prior to that time,
such functions were conducted at the Company's former headquarters in Beaverton,
Oregon. During the fourth quarter of 1997, the Company relocated its wafer
fabrication and all other remaining operations to the new Hillsboro site. The
Company's lease of its former wafer fabrication and manufacturing facility, a
facility located in Beaverton, Oregon and owned by Maxim Integrated Products,
Inc., expired in January, 1998. The Hillsboro wafer fabrication facility
consists of 38,000 square feet, of which 17,000 is operated as a class 10
performance clean room.

    The Company's Texas facility is located in Dallas, Texas. The Texas facility
comprises approximately 100,000 square feet, of which 15,000 square feet is
operated as a Class 10 performance clean room. The Texas facility is subleased
from RTIS, which leases the premises from Texas Instruments, through July 10,
2002. The Company has the right to renew its sublease of this facility for up to
three additional five year periods in the event that RTIS exercises its rights
to renew its lease from Texas Instruments. There can be no assurance, however,
that RTIS will extend its lease beyond July 10, 2002.
 
    The fabrication of semiconductor products is highly complex and sensitive to
dust and other contaminants, requiring production in a highly controlled, clean
environment. Minute impurities, difficulties in the fabrication process or
defects in the masks used to print circuits on the wafers can cause a
substantial percentage of the wafers to be rejected or numerous die on each
wafer to be nonfunctional. As compared to silicon technology, the less mature
stage of GaAs technology leads to somewhat greater difficulty in circuit design
and in controlling parametric variations, thereby yielding fewer good die per
wafer. The more brittle nature of GaAs wafers can lead to higher processing
losses than experienced with silicon wafers. To maximize wafer yield and
quality, the Company tests its products in various stages in the fabrication
process, maintains continuous reliability monitoring and conducts numerous
quality control inspections throughout the entire production flow using
analytical manufacturing controls. A sustained failure to maintain acceptable
yields would have a material adverse effect on the Company's operating results.
 
    The Company's operation of its own manufacturing facilities entails a high
level of fixed costs. Such fixed costs consist primarily of facility occupancy
costs, investment in manufacturing equipment, repair, maintenance and
depreciation costs related to equipment and fixed labor costs related to
manufacturing and process engineering. The Company's manufacturing yields vary
significantly among its products, depending upon a given product's complexity
and the Company's experience in manufacturing such product. The Company has in
the past and may in the future experience substantial delays in product
shipments due to lower than expected production yields. In addition, during
periods of low demand, high fixed wafer fabrication costs could have a material
adverse effect on the Company's operating results.
 
    Employees of the Company have performed studies of the reliability of the
Company's processes and have published more than 25 technical papers in such
field. In October 1994, the Company received the ISO 9001 Quality System
Certification with respect to its operations. The Company has successfully
fabricated devices for "High Reliability" applications in commercial and
military spacecraft since 1988. Through accelerated test techniques, the Company
has demonstrated expected device failure rates of less than 100FITs (100
failures in 1 billion device-hours of operation) in the first twenty years of
operation at maximum junction temperatures of 150 degrees Celsius. The
reliability of the Company's processes may be inadvertently reduced by future
engineering changes and the reliability of any given integrated circuit may be
strongly influenced by design details, and there can be no assurance that
circuits designed and manufactured in the future will achieve this level of
reliability.
 
    Wafer fabrication equipment used by the Company is generally the same as
that used in a submicron silicon metal oxide semiconductor ("MOS") fabrication
facility. While many of the process steps are also similar to those commonly
used in silicon wafer manufacturing, TriQuint's GaAs manufacturing process has
important differences. The GaAs process requires fewer steps and may be
conducted at lower temperatures than those typically required in high
performance silicon processes. Furthermore, GaAs wafers require more rigorous
handling procedures than do silicon wafers.
 
    The raw materials and equipment used in the production of the Company's
integrated circuits are available from several suppliers. The Company currently
has approximately seven fully qualified wafer vendors, at least three of which
are located in the United States, and two fully qualified mask set vendors, one
of which is located in the United States.
 
    The Company assembles its products using outside assembly contractors.
Outside assembly and tape and reel services for volume production are contracted
to ten vendors, three of which are located in the
 
                                       9
<PAGE>
United States. The Company purchases high performance, multilayer ceramic
packages from two vendors, one of which is located in the United States.
TriQuint believes it was the first supplier of GaAs integrated circuits to
introduce plastic packages in volume production. The Company currently purchases
plastic packaging services from six suppliers, one of which is located in the
United States. A reduction or interruption in the performance of assembly
services by subcontractors or a significant increase in the price changed for
such services could adversely affect the Company's operating results.
 
SALES AND DISTRIBUTION
 
    The Company sells its products through independent manufacturer's
representatives and distributors and through a direct sales staff. As of
December 31, 1998, TriQuint had 21 independent manufacturer's representative
firms and two distributors in North America. TriQuint's seven person direct
sales management staff provides sales direction and support to the
manufacturer's representatives and distributors. Domestic sales management
offices are located in the metropolitan areas of Los Angeles, California;
Philadelphia, Pennsylvania; Portland, Oregon; San Jose, California and Raleigh,
North Carolina. International business is supported by a network of 15
manufacturer's representatives and distributors in Europe and the Pacific Rim.
The Company has also established a foreign subsidiary, TriQuint Semiconductor
GmbH, with offices in Germany and France. The primary activity of this
subsidiary is sales and marketing. Sales outside of the United States were $26.8
million, $24.3 million and $18.1 million in 1998, 1997 and 1996, respectively.
All international sales of the Company's products are denominated in U.S.
dollars in order to reduce the exchange rate risks. Sales outside of the United
States involve a number of inherent risks, including reduced protection for
intellectual property rights in some countries, the impact of recessionary
environments in economies outside of the United States and generally longer
receivables collection periods, as well as tariffs and other trade barriers. In
addition, due to the technological advantage provided by GaAs in military
applications, all export sales must be licensed by the Office of Export
Administration of the U.S. Department of Commerce. Although the Company has
experienced no difficulty in obtaining these licenses, failure to obtain these
licenses in the future could have a material adverse effect on the Company's
results of operations.
 
    The Company includes in its backlog all purchase orders and contracts for
products requested by the customer for delivery within twelve months. The
Company's business is characterized by long-term purchase contracts
predominantly relating to customer-specific products, which are typically
cancelable without significant penalty, at the option of the purchaser.
Cancellations of such purchase contracts or rescheduling of delivery dates have
occurred in the past and may occur in the future. The Company also produces
standard products which frequently can be shipped from inventory within a short
time after receipt of an order and therefore such orders may not be reflected in
backlog. Accordingly, backlog as of any particular date may not necessarily be
representative of actual sales for any future period.
 
RESEARCH AND DEVELOPMENT
 
    The Company's research and development efforts are focused on the design of
new integrated circuits, improvement of existing device performance, development
of new processes, cost reductions in the manufacturing process and improvements
in device packaging. New product developments include standard and
customer-specific devices for satellite communications, cellular and PCS
telephones, wireless local area networks, wireless modems, high performance
switching, transmission and data conversion products and data communications
chipsets.
 
    The Company's research, development and engineering ("RD&E") expenses in
1998, 1997 and 1996 were approximately $19.0 million, $11.5 million and $10.9
million, respectively, and include non-recurring engineering ("NRE") expenses
funded by customers. Expenses in 1998 related to RD&E increased substantially
from the level incurred in 1997 primarily due to the inclusion of the new
Millimeter Wave Communications operation. As of December 31, 1998, there were
approximately 245 employees engaged
 
                                       10
<PAGE>
in activities related to process and product research and development. The
Company expects that it will continue to spend substantial funds on research and
development.
 
    The Company is continually in the process of designing new and improved
products to maintain its competitive position. While the Company has patented a
number of aspects of its process technology, the market for the Company's
products is characterized by rapid changes in both GaAs and competing silicon
process technologies. Because of continual improvements in these technologies,
the Company believes that its future success will depend on its ability to
continue to improve its products and processes and develop new technologies in
order to remain competitive. Additionally, the Company's future success will
depend on its ability to develop and introduce new products for its target
markets in a timely manner. The success of new product introductions is
dependent upon several factors, including timely completion and introduction of
new product designs, achievement of acceptable fabrication yields and market
acceptance. The development of new products by the Company and their design into
customers' systems can take as long as three years, depending upon the
complexity of the device and the application. Accordingly, new product
development requires a long-term forecast of market trends and customer needs.
Furthermore, the successful introduction of the Company's ongoing products may
be adversely affected by the competing products or technologies serving markets
addressed by the Company's products. In addition, new product introductions
frequently depend on the Company's development and implementation of new process
technologies. If the Company is unable to design, develop, manufacture and
market new products successfully, its future operating results will be adversely
affected. No assurance can be given that the Company's product and process
development efforts will be successful or that its new products will be
available on a timely basis or achieve market acceptance. In addition, as is
characteristic of the semiconductor industry, the average selling prices of the
Company's products have historically decreased over the products' lives and are
expected to continue to do so. To offset such decreases, the Company relies
primarily on obtaining yield improvements and corresponding cost reductions in
the manufacture of existing products and on introducing new products which
incorporate advanced features and which therefore can be sold at higher average
selling prices. To the extent that such cost reductions and new product
introductions do not occur in a timely manner or the Company's or its customers'
products do not achieve market acceptance, the Company's operating results could
be adversely affected.
 
COMPETITION
 
    The market for high performance semiconductors is highly competitive and
subject to rapid technological change. Due to the increasing requirements for
high speed components, the Company expects intensified competition from existing
silicon device suppliers and the entry of new competition producing either
silicon or GaAs components or components incorporating new technologies such as
silicon germanium. The Company currently competes against silicon products
offered principally by large semiconductor manufacturers such as AMCC, Motorola
and Philips. In addition, the Company also currently competes against other GaAs
semiconductor manufacturers, such as Anadigics, Vitesse, RF Microdevices and
Raytheon. It is expected that additional future competition will primarily come
from large semiconductor companies that have developed GaAs integrated circuit
capabilities such as Fujitsu, Motorola and NEC. Such companies have
substantially greater technical, financial and marketing resources and name
recognition than the Company. Increased competition could adversely affect the
Company's revenue and profitability.
 
    GaAs integrated circuits have been used mostly in the wireless
communications market on a production basis for products or subsystems operating
below 1 GHz, such as spread spectrum and cellular telephone applications. As the
lower frequency bands become more crowded, more applications will utilize
frequencies above 1 GHz. At such higher frequencies, GaAs integrated circuit
solutions generally provide superior performance as compared to silicon
alternatives. TriQuint competes with both GaAs and silicon suppliers in the
telecommunications market. In the computing market, TriQuint supplies standard
products to a variety of data communication systems manufacturers. In the
computing market, the Company's
 
                                       11
<PAGE>
competition comes from established silicon semiconductor companies and GaAs
suppliers, and is generally based on performance elements such as speed, power
dissipation, price, product quality and service. In the microwave and millimeter
wave markets, the Company's competition is primarily from a limited number of
military and aerospace based suppliers who are in the process of expanding their
products to cover commercial opportunities as well.
 
    The Company's prospective customers are typically systems designers and
manufacturers who are considering the use of GaAs semiconductors in their next
high performance systems. Competition is primarily based on performance elements
such as speed, complexity and power dissipation, as well as price, product
quality and ability to deliver products in a timely fashion. The Company
believes that it currently competes favorably with respect to these factors. Due
to the proprietary nature of the Company's products, competition occurs almost
exclusively at the system design stage. As a result, a design win by the Company
or its competitors typically limits further competition with respect to
manufacturing a given design. Some potential customers may be reluctant to adopt
the Company's products because of perceived risks relating to GaAs technology
generally, including perceived risks related to manufacturing costs, novel
design and unfamiliar manufacturing processes. In addition, potential customers
may have questions about the relative performance advantages of the Company's
products compared to more familiar silicon semiconductors, or concerns about
risks associated with reliance on a smaller, less well-capitalized company for a
critical component. While GaAs integrated circuits have inherent speed
advantages over silicon devices, the speed of products based upon silicon
processes is continually improving. The Company's products are generally sole
sourced to its customers, and the Company's operating results could be adversely
affected if its customers were to develop other sources for the Company's
products.
 
    The production of GaAs integrated circuits has been and continues to be more
costly than the production of silicon devices. This cost differential relates
primarily to higher costs of the raw wafer material, lower production yields
associated with the relatively immature GaAs technology and higher unit costs
associated with lower production volumes. Although the Company has reduced
production costs through decreasing raw wafer costs, increasing fabrication
yields and achieving higher volumes, there can be no assurance that the Company
will be able to continue to decrease production costs. In addition, the Company
believes its costs of producing GaAs integrated circuits will continue to exceed
the costs associated with the production of silicon devices. As a result, the
Company must offer devices which provide superior performance to that of silicon
such that the perceived price/performance of its products is competitive with
silicon devices. There can be no assurance that the Company can continue to
identify markets which require performance superior to that offered by silicon
solutions or that the Company will continue to offer products which provide
sufficiently superior performance to offset the cost differentials.
 
PATENTS AND LICENSES
 
    The Company aggressively seeks the issuance of patents to protect inventions
and technology which are important to its business. The Company has been awarded
numerous patents for circuit design and wafer processing; with various
expiration dates, none earlier than April 2005. These include both U.S. and
foreign patents. As part of the acquisition of the Millimeter Wave
Communications operation in January 1998, the Company acquired certain patents
and also received licenses and sublicenses for certain additional patents. In
addition, the Company has both U.S. and foreign registered trademarks. The
Company has also routinely protected its numerous original mask sets under the
copyright laws. There can be no assurance that the Company's pending patent or
trademark applications will be allowed or that the issued or pending patents
will not be challenged or circumvented by competitors.
 
    Notwithstanding the Company's active pursuit of patent protection, the
Company believes that its future success will depend primarily upon the
technical expertise, creative skills and management abilities of its officers
and key employees rather than on patent ownership. The Company also relies
substantially on trade secrets and proprietary technology to protect its
technology and manufacturing know-how, and works actively to foster continuing
technological innovation to maintain and protect its competitive position. There
can be no assurance that the Company's competitors will not independently
develop or patent substantially equivalent or superior technologies.
 
                                       12
<PAGE>
    On February 26, 1999, a lawsuit was filed against 88 firms, including the
Company, in the United States District Court for the District of Arizona. The
suit alleges that the defendants infringe upon certain patents held by The
Lemelson Medical, Education and Research Foundation, Limited Partnership. The
Company believes that the suit is without merit and intends to vigorously defend
itself against the charges.
 
    The Company's involvement in any patent dispute or other intellectual
property dispute or action to protect trade secrets and know-how could have a
material adverse effect on the Company's business. Adverse determinations in any
litigation could subject the Company to significant liabilities to third
parties, require the Company to seek licenses from third parties and prevent the
Company from manufacturing and selling its products. Any of these situations
could have a material adverse effect on the Company's business.
 
ENVIRONMENTAL MATTERS
 
    Federal, state and local regulations impose various environmental controls
on the storage, handling, discharge and disposal of chemicals and gases used in
TriQuint's manufacturing process. For the manufacturing facilities located at
Hillsboro, Oregon, the Company is providing for its own manufacturing waste
treatment and disposal. The Company is required by the State of Oregon
Department of Environmental Quality to report usage of environmentally hazardous
materials and has retained the appropriate personnel to help ensure compliance
with all applicable environmental regulations.
 
    At the Texas facility, the Company utilizes TI's waste treatment and waste
storage facilities and services for the treatment, storage, disposal and
discharge of wastes generated by the Company, pursuant to the Asset Purchase
Agreement dated January 8, 1998. The Company's waste streams are commingled with
those of TI and are covered by the TI waste water permit.
 
    The Company believes that its activities conform to present environmental
regulations. Increasing public attention has, however, been focused on the
environmental impact of semiconductor operations. While the Company has not
experienced any materially adverse effects on its operations from environmental
regulations, there can be no assurance that changes in such regulations will not
impose the need for additional capital equipment or other requirements. Any
failure by the Company, or by TI with respect to the Texas facility, to
adequately restrict the discharge of hazardous substances could subject the
Company to future liabilities or could cause its manufacturing operations to be
suspended.
 
EMPLOYEES
 
    As of December 31, 1998, the Company employed a total of 679 persons,
including 316 in manufacturing, 18 in quality and reliability, 245 in process,
product and development engineering, 41 in marketing and sales and 59 in finance
and administration. None of the Company's employees are represented by a
collective bargaining agreement, nor has the Company experienced any work
stoppage. The Company considers its relations with employees to be good.
 
ITEM 2.  PROPERTIES
 
    The Company moved its executive, administrative, test and technical offices
to a new 124,000 square foot leased facility in Hillsboro, Oregon in the first
quarter of 1997. Prior to that time, such functions were conducted at the
Company's former headquarters in Beaverton, Oregon. During the fourth quarter of
1997, the Company completed the relocation of its wafer fabrication and all
other remaining operations to the new Hillsboro site. The leased Hillsboro wafer
fabrication facility consists of 38,000 square feet, of which 17,000 is operated
as a class 10 performance clean room.
 
    In May 1996, the Company entered into a five year synthetic lease through a
Participation Agreement (the "Agreement") with Wolverine Leasing Corp.
("Wolverine"), Matisse Holding Company ("Matisse") and United States National
Bank of Oregon ("USNB"). The lease provides for the construction and
 
                                       13
<PAGE>
occupancy of the Company's Hillsboro facility under an operating lease from
Wolverine and provides the Company with an option to purchase the property or
renew its lease for an additional five years. Pursuant to the terms of the
Agreement, the USNB and Matisse made loans to Wolverine who in turn advanced the
funds to the Company for the construction of the Hillsboro facility and other
costs and expenses associated therewith. The loan from USNB is collateralized by
investment securities pledged by the Company. Such investment securities are
classified on the Company's balance sheet as restricted investments. In
addition, restrictive covenants in the Agreement require the Company to maintain
(i) a total liability to tangible net worth ratio of not more than 0.75 to 1.00,
(ii) minimum tangible net worth greater than $50.0 million and (iii) cash and
liquid investment securities, including restricted securities, greater than
$45.0 million. As of December 31, 1998, the Company was in compliance with the
covenants described above, and the Company anticipates that it will be in
compliance with the covenants as of March 31, 1999. However, there can be no
assurance that the Company will continue to be in compliance with these
covenants in the future.
 
    In November 1997, the Company entered into a $1.5 million lease agreement
for additional land adjacent to its Hillsboro facility. Pursuant to the terms of
that agreement, USNB provided loans to Matisse to purchase the land, who in turn
leased it to the Company under a renewable one year lease agreement. The loan
from USNB is partially collateralized by a guarantee from the Company. The
agreement contains restrictive covenants substantially the same as those
contained in the Company's line of credit. As of December 31, 1998 the Company
was in compliance with the terms of the agreement. However, there can be no
assurance that the Company will continue to be in compliance with these terms as
of any subsequent date.
 
    In January 1998, the Company acquired the Millimeter Wave Communications
operations of the former Texas Instruments' Defense Systems & Electronics Group
from RTIS. The Millimeter Wave Communications facilities are located in Dallas,
Texas. The Texas facility comprises approximately 100,000 square feet, of which
15,000 square feet is operated as a Class 10 performance clean room. The Texas
facility is subleased from RTIS, which leases the premises from Texas
Instruments, through July 10, 2002. The Company has the right to renew its
sublease of the Texas facility for up to three additional five year periods in
the event that RTIS exercises its rights to renew its lease from Texas
Instruments. There can be no assurance, however, that RTIS will extend its lease
beyond July 10, 2002.
 
ITEM 3.  LEGAL PROCEEDINGS
 
    On July 12, 1994, a stockholder class action lawsuit was filed against the
Company, its underwriters, and certain of its officers, directors and investors
in the United States District Court for the Northern District of California. The
suit alleged that the Company, its underwriters, and certain of its officers,
directors and investors intentionally misled the investing public regarding the
financial prospects of the Company. Following the filing of the complaint, the
plaintiffs dismissed without prejudice a director defendant, the principal
stockholder defendant, the underwriter defendants and certain analyst
defendants. On June 21, 1996, the Court granted the Company's motion to transfer
the litigation to the District of Oregon. The pretrial discovery phase of the
lawsuit ended July 1, 1997. The Court had established a January 1999 trial date
for this action. During the year ended December 31, 1998, the Company settled
this action and recorded a special charge of $1.4 million associated with the
settlement of this lawsuit and related legal expenses, net of accruals.
 
    On February 26, 1999, a lawsuit was filed against 88 firms, including the
Company, in the United States District Court for the District of Arizona. The
suit alleges that the defendants infringe upon certain patents held by The
Lemelson Medical, Education and Research Foundation, Limited Partnership. The
Company believes that the suit is without merit and intends to vigorously defend
itself against the charges.

OVERVIEW

TriQuint Semiconductor designs, develops, manufactures and markets a broad 
range of high-performance analog and mixed-signal gallium arsenide (GaAs) 
integrated circuits and transistors for the wireless communications, 
telecommunications, data communications and millimeter wave communications 
markets. TriQuint's engineers apply the company's proprietary GaAs technology 
to produce high-performance, low-cost devices that give customers a 
competitive edge in their product strategy. TriQuint offers a broad range of 
standard and customer-specific products as well as manufacturing services.

Inherent physical properties allow electrons to move approximately 
five times faster in GaAs than in silicon. This enables GaAs 
integrated circuits to operate at much higher frequencies than 
silicon devices--or to perform as fast while using substantially 
less power. GaAs also provides lower distortion amplification, can 
receive weaker signals due to its low-noise characteristics, and 
can transmit strong clean signals at lower voltages.

TriQuint's wafer fabrication facilities, located in Oregon and Texas, produce 
4-inch wafers using high-volume, low-cost ion-implanted metal semiconductor 
field effect transistor (MESFET) processes, high power and efficiency 
pseudomorphic high electron mobility transfer (PHEMT), heterojunction bipolar 
transistor (HBT) and heterojunction field effect transistor (HFET) processes. 
All TriQuint operations are ISO 9001 certified.

End-user customers include market-leading equipment manufacturers such as 
Alcatel, Cellnet Data Systems, Ericsson, Hughes, Lucent Technologies, 
Motorola, Nokia, Nortel, Qualcomm, and Raytheon.

TO OUR SHAREHOLDERS: 1998 SAW OUR COMPANY'S REVENUES PASS THE $100 MILLION 
MILESTONE. WE GREATLY EXPANDED OUR TECHNOLOGY CAPABILITIES AND MARKET BASE 
WITH THE ACQUISITION OF THE MILLIMETER WAVE BUSINESS AND ARE EXTREMELY WELL 
POSITIONED TO SUCCESSFULLY PARTICIPATE IN A BROAD ARRAY OF HIGH GROWTH 
COMMUNICATIONS MARKET OPPORTUNITIES.

FINANCIAL PERFORMANCE. 1998 revenues increased by 56% over 1997 to a record 
$111.6 million. For the year, we reported a net loss of $4.0 million. 
Excluding the first quarter, which produced a loss due to special charges 
primarily associated with the acquisition of the Millimeter Wave business, 
our net profit for 1998 was $8.3 million. Our balance sheet remains very 
strong.

MILLIMETER WAVE COMMUNICATIONS. Early in the year we announced the 
acquisition of the Gallium Arsenide (GaAs) millimeter wave integrated circuit 
operation of the former Texas Instruments Defense Systems and Electronics 
Group from Raytheon for approximately $39 million. This operation is a world 
leader in millimeter wave integrated circuit technology. Millimeter wave 
devices operate at frequencies above 10 GHz and are a perfect complement to 
our Oregon product lines. I am happy to report that the integration of the 
Millimeter Wave business, which is located in Dallas, has gone extremely well 
and results have exceeded our expectations. We are very pleased with the 
strong performance of the Millimeter Wave team. With the addition of 
Millimeter Wave, we now possess the full range of advanced GaAs processes - 
MESFET, PHEMT, HBT and HFET - that provide the performance capability 
required for the wide array of present and emerging high growth 
communications opportunities.

CUSTOMER AND MARKET DIVERSITY. Rather than be dependent on a relatively narrow
customer and applications base, we have purposely sought to engage with all the
leading

<PAGE>

participants in each of the major communications markets where our 
proprietary technologies provide a competitive advantage. In 1998, just two 
customers represented over 10% of our revenues. Nokia, the leading wireless 
telephone handset manufacturer was our largest customer at 12% and Raytheon 
was the second largest at 11.7%. Twenty-one end-customers contributed over $1 
million in revenue during the year. Our applications portfolio was also well 
balanced with approximately 45% of revenues from wireless communications 
applications, 18% in the telecom/ datacom arena and 37% from millimeter wave 
systems. The addition of millimeter wave technologies to our product 
offerings has allowed us to expand our participation in entirely new market 
areas including satellite communications, point-to-point and 
point-to-multipoint broadband communications, Local Multipoint Distribution 
Systems (LMDS) and advanced aerospace systems.

DESIGN WINS AND NEW PRODUCTS. By focusing our marketing and sales efforts, we 
were able to achieve a record 246 major design wins during the year, up from 
131 in 1997. Since all our products are proprietary, sole source devices, 
design wins are a critical activity and, we believe, are a good leading 
indicator of future business. Wireless product introductions during the year 
included a family of three volt power amplifiers for wireless handset 
transmitters and further expansion of our handset receiver product line. We 
also announced the inclusion of a new mixer/downconverter in the reference 
design chip set for implementation of Motorola's ReFlex two-way messaging 
protocol. The telecom product line was expanded with the introduction of two 
high speed cross-point switches and a 2.5 Gigabit per second transceiver for 
high performance networks and SONET fiber optic communications applications. 
The millimeter wave product line announced a family of high efficiency and 
high linearity power transistors in the DC to 12GHz frequency range, a high 
power 6.5 to 11.5 GHz amplifier for digital radio, phased array radar, and 
telecommunications applications and also a 28 GHz Amplifier for the Digital 
Radio, LMDS and satellite communications markets.

<PAGE>

OPERATIONS. During the first quarter of the year, we transitioned to our new
state-of-the-art Oregon wafer fab facility. Since that time, we have seen a
steady improvement in output and yields from the new fab. We estimate that this
facility, combined with the Texas wafer fab, provides us with the physical
capacity to support up to $300M in annual sales. Both facilities have been
certified to the requirements of the ISO 9001 International Quality Standard.

ORGANIZATION. Until mid 1998, we maintained our foundry services operations as
part of the Wireless Communications organization. In June, we formed a separate
Foundry Services Division to focus on the unique requirements of our foundry
customers. TriQuint's design tools and technical support enable our customers to
design their own circuits for manufacture by us on our proprietary processes.
The foundry relationship enables our customers to rapidly introduce leadership
devices while protecting their intellectual property. Bruce Fournier, formerly
Vice President of Sales heads the new Foundry Services Division. Replacing Bruce
is Paul Kollar who brings more than thirty years of experience in semiconductor
marketing and sales management to his new position. Paul was most recently Vice
President of sales at Lattice Semiconductor and is a strong addition to our
management team.

We continue to see excellent results from our company-wide continuous process
improvement initiatives. Employee participation in the continuous improvement of
all our business processes has become even more firmly embedded in our culture
during the past 12 months.

THE COMING YEAR. Looking ahead, we anticipate continued revenue growth in 1999.
The wireless communications market is expected to drive much of this growth. The
market for our high performance telecom products should also be strong and we
expect to see exceptional design win opportunities in satellite communications
and LMDS applications. We will continue to concentrate on driving our design win
activities and on maintaining our broad, well-balanced product portfolio and
market base.

<PAGE>

In summary, 1998 was another very successful year for TriQuint. We significantly
strengthened our product offerings, broadened our market and customer base and
positioned our manufacturing operations to support the anticipated rapid growth
of our business. The enthusiasm and teamwork of our employees and the support of
our customers, suppliers, and shareholders has made this possible and is
sincerely appreciated. We look forward to continuing our success in this very
exciting and opportunity-filled business.

Sincerely,



Steven J. Sharp
CHAIRMAN, PRESIDENT & CHIEF EXECUTIVE OFFICER

INTRODUCTION

         TriQuint Semiconductor, Inc. (TriQuint or the Company) designs,
develops, manufactures and markets a broad range of high performance analog and
mixed signal integrated circuits for the communications markets. The Company
utilizes its proprietary gallium arsenide (GaAs) technology to enable its
products to overcome the performance barriers of silicon devices in a variety of
applications. The Company sells its products on a worldwide basis and its end
user customers include Alcatel, Cellnet Data Systems, Ericsson, Hughes, Lucent
Technologies, Motorola, Nokia, Northern Telecom, Qualcomm and Raytheon.

         On January 13, 1998, the Company acquired substantially all of the
assets of the Monolithic Microwave Integrated Circuit (MMIC) operations of the
former Texas Instruments' Defense Systems & Electronics Group from Raytheon TI
Systems, Inc. (RTIS), a Delaware corporation and a wholly owned subsidiary of
Raytheon Company (Raytheon). The MMIC operations include the GaAs foundry and
MMIC business of the R/F Microwave Business Unit that RTIS acquired on July 11,
1997 from Texas Instruments Incorporated (TI) which MMIC business includes
without limitation, TI's GaAs Operations Group, TI's Microwave GaAs Products
Business Unit, the MMIC component of TI's Microwave GaAs Products Business Unit,
the MMIC component of TI's Microwave Integrated Circuits Center of Excellence
and the MMIC research and development component of TI's Systems Component
Research Laboratory (collectively, Millimeter Wave Communications).

         The Millimeter Wave Communications operation designs, develops,
produces and sells advanced GaAs MMIC products which are used in defense and
commercial applications. In the area of defense applications, the Millimeter
Wave Communications operation supplies military contractors with MMIC products
and services for applications such as high power amplifiers, low noise
amplifiers, switches and attenuators for active array radar, missiles,
electronic warfare systems and space communications systems. In commercial
applications, the Millimeter Wave Communications operation provides products and
services for wireless and space-based communications.

         Pursuant to an Asset Purchase Agreement with RTIS, TriQuint acquired
the Millimeter Wave Communications operation for approximately $19.5 million in
cash and 844,613 shares of TriQuint Common Stock valued at approximately $19.5
million for a total purchase consideration of approximately $39 million. The
cash portion of the purchase price was financed through an operating lease
arrangement involving certain assets pursuant to the Agreement.

</TABLE>

The fiscal years ended December 31, 1998, December 31, 1997 and December 31,
1996 are hereinafter referred to as Fiscal 1998, Fiscal 1997 and Fiscal 1996,
respectively.

COMPARISON OF 1998 AND 1997

TOTAL REVENUES

         The Company derives revenues from the sale of standard and 
customer-specific products and services. The Company's revenues also include 
non-recurring engineering (NRE) revenues relating to the development of 
customer-specific products. Total revenues for Fiscal 1998 increased 56.4% to 
$111.6 million from $71.4 million for Fiscal 1997. The increase in total 
revenues primarily reflects the inclusion of revenues from the newly acquired 
Millimeter Wave Communications operation since the date of acquisition and a 
strong demand for wireless communication products, offset by a reduction in 
demand for telecommunication products. Domestic and international revenues 
for Fiscal 1998 were $84.8 million and $26.8 million, respectively, as 
compared to $47.1 million and $24.3 million, respectively, for Fiscal 1997. 
The Company currently anticipates an overall increase in the volume of 
product revenues from existing and new customers.

COST OF GOODS SOLD

         Cost of goods sold includes all direct material, labor and overhead
expenses and certain NRE production costs. The factors affecting product mix
include the relative demand in the various markets incorporating the Company's
customer-specific products and standard products, as well as the number of NRE
contracts which result in volume requirements for customer-specific products.
Cost of goods sold was $72.8 million in Fiscal 1998 and increased from $40.0
million in Fiscal 1997. Cost of goods sold for Fiscal 1998 increased as a
percentage of total revenues to 65.2% from 56.1% for Fiscal 1997. The increase
in absolute dollar value of cost of goods sold was primarily attributable to the
related increase in sales volume. The increase in cost of goods sold as a
percentage of total revenues was due to an increase in lower-margin products in
the mix of products sold and costs related to the transition to the Company's
new Hillsboro wafer fabrication facility. However, cost of goods sold, as a
percentage of total revenues, improved sequentially over each quarter of Fiscal
1998 due to continued yield improvements and increases in economies of scale
from higher production volumes.

                                       2
<PAGE>

         The Company has at various times in the past experienced lower than
expected production yields which have delayed shipments of a given product and
adversely affected gross margins. There can be no assurance that the Company
will be able to maintain acceptable production yields in the future and, to the
extent that it does not achieve acceptable production yields, its operating
results would be materially adversely affected. The Company's operation of its
own leased wafer fabrication facility entails a high degree of fixed costs and
requires an adequate volume of production and sales to be profitable. During
periods of decreased demand, high fixed wafer fabrication costs would have a
material adverse effect on the Company's operating results.

RESEARCH, DEVELOPMENT AND ENGINEERING

         Research, development and engineering (RD&E) expenses include the costs
incurred in the design of products associated with NRE revenues, as well as
ongoing product development and research and development expenses. The Company's
RD&E expenses for Fiscal 1998 increased 64.8% to $19.0 million from $11.5
million for Fiscal 1997. RD&E expenses as a percentage of total revenues
increased to 17.0% for Fiscal 1998 from 16.1% for Fiscal 1997. The increase in
RD&E expenses in both absolute dollar amount and as a percentage of total
revenues reflects the inclusion of RD&E expenses related to the newly acquired
MMIC Business and increases in product development activities and NRE expenses.
The Company is committed to substantial investments in RD&E and expects such
expenses will increase in absolute dollar amount in the future.

SELLING, GENERAL AND ADMINISTRATIVE

         Selling, general and administrative (SG&A) expenses for Fiscal 1998
increased 12.5% to $16.0 million from $14.2 million for Fiscal 1997. SG&A
decreased as a percentage of total revenues to 14.3% for 1998 from 19.9% for
1997. The increase in absolute dollar value in SG&A expenses was primarily
attributable to the inclusion of SG&A expenses related to the newly acquired
Millimeter Wave Communications operation and increased selling expenses
associated with increased sales volume. As a percentage of total revenues, the
decrease in SG&A expenses was due to revenues increasing at a faster rate than
SG&A expenses.

SPECIAL CHARGES

         During Fiscal 1998, special charges of $8.8 million were recorded.
These were special charges associated with the Company's acquisition of the MMIC
Business from Raytheon TI Systems, Inc. and involve the write-off of the fair
value of in-process research and development.

         On July 12, 1994, a stockholder class action lawsuit was filed against
the Company, its underwriters, and certain of its officers, directors and
investors in the United States District Court for the Northern District of
California. The suit alleged that the Company, its underwriters, and certain of
its officers, directors and investors intentionally misled the investing public
regarding the financial prospects of the Company. Following the filing of the
complaint, the plaintiffs dismissed without prejudice a director defendant, the
principal stockholder defendant, the underwriter defendants and certain analyst
defendants. On June 21, 1996, the Court granted the Company's motion to transfer
the litigation to the District of Oregon. The pretrial discovery phase of the
lawsuit ended July 1, 1997. The Court had established a January 1999 trial date
for this action. During Fiscal 1998, the Company settled this action and
recorded a special charge of $1.4 million associated with the settlement of
this lawsuit and related legal expenses, net of accruals and insurance proceeds.

OTHER INCOME, NET

         Other income, net for Fiscal 1998 increased to $2.5 million as compared
to $2.1 million for Fiscal 1997. This increase resulted primarily from lower
interest expense, gain on sale of assets and other miscellaneous receipts,
partially offset by lower interest income.

                                       3
<PAGE>

INCOME TAX EXPENSE

         Income tax expense for Fiscal 1998 decreased to $94,000 from $890,000
for Fiscal 1997. The decrease in income tax expense was attributable to the
Company's operating loss in Fiscal 1998.

         At December 31, 1998, the Company had federal and Oregon state net
operating loss carryforwards for tax reporting purposes of approximately $45.7
million and $22.0 million, respectively. The Company's ability to use its net
operating loss carryforwards against taxable income is subject to additional
restrictions and limitations under Section 382 of the Internal Revenue Code of
1986, as amended, in the event of a change of ownership of the Company as
defined therein. See Note 7 of Notes to Consolidated Financial Statements.

COMPARISON OF 1997 AND 1996

TOTAL REVENUES

         Total revenues for Fiscal 1997 increased 19.9% to $71.4 million from
$59.5 million for Fiscal 1996. The increase in total revenues was due to
significantly increased demand for products in all three product areas: wireless
communications, telecommunications, and computing revenues. Domestic and
international revenues for Fiscal 1997 were $47.1 million and $24.3 million,
respectively, as compared to $41.4 million and $18.1 million, respectively, for
Fiscal 1996.

COST OF GOODS SOLD

         Cost of goods sold was $40.0 million in Fiscal 1997 and increased from
$34.3 million in Fiscal 1996. Cost of goods sold for Fiscal 1997 decreased
slightly as a percentage of total revenues to 56.1% from 57.6% for Fiscal 1996.
The decrease in cost of goods sold as a percentage of total revenues was
primarily attributable to improvements in production yields and increased
volume, which were partially offset by certain costs associated with the
Company's startup of its new wafer fabrication facility and variances associated
with expediting costs.

RESEARCH, DEVELOPMENT AND ENGINEERING

         The Company's RD&E expenses for Fiscal 1997 increased 6.1% to $11.5
million from $10.9 million for Fiscal 1996. RD&E expenses as a percentage of
total revenues decreased to 16.1% for Fiscal 1997 from 18.2% for Fiscal 1996.
The increase in RD&E expenses in absolute dollar level was primarily due to
increased product development activities and NRE expenses in response to
increased demand from customers. The number of major design wins for Fiscal 1997
increased 17% from Fiscal 1996.

SELLING, GENERAL AND ADMINISTRATIVE

         Selling, general and administrative (SG&A) expenses for Fiscal 1997
increased 29.3% to $14.2 million from $11.0 million for Fiscal 1996. SG&A
increased as a percentage of total revenues to 19.9% for 1997 from 18.4% for
1996. The increase in the level of SG&A expenses was primarily due to costs
associated with the Company's move to its new facility in Hillsboro, increased
information technology support costs, increased sales commissions in connection
with the increase in the level of total revenues, and professional fees.

OTHER INCOME , NET

         Other income, net for Fiscal 1997 decreased to $2.1 million as compared
to $3.1 million for Fiscal 1996. This decrease resulted from a one-time gain of
$680,000 from the sale of the Company's minority interest in its primary
distributor in Europe in Fiscal 1996 and from higher interest expense in Fiscal
1997 associated with an increase in capital lease obligations.

                                       4
<PAGE>

INCOME TAX EXPENSE

         The effective tax rate for Fiscal 1997 was 11.5%, which is less than
the federal and state statutory rate of approximately 40% due to the use of net
operating loss carryforwards. The effective tax rate for Fiscal 1996 was 3.5%.


NEW ACCOUNTING STANDARDS

         In April 1998, the AICPA issued Statement of Position 98-5, "Reporting
on the Costs of Start-Up Activities", ("SOP 98-5"), which is effective for
financial statements for fiscal years beginning after December 15, 1998. SOP
98-5 broadly defines start-up activities and requires costs of start-up
activities and organization costs to be expensed as incurred. The Company does
not expect implementation to have a significant impact on its consolidated
financial statements.

         In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities". SFAS No. 133 establishes accounting and
reporting standards requiring that every derivative instrument be recorded in
the balance sheet as either an asset or liability measured at its fair value.
SFAS No. 133 also requires that changes in the derivative's fair value be
recognized currently in results of operations unless specific hedge accounting
criteria are met. SFAS No. 133 is effective for fiscal years beginning after
June 15, 1999. The Company does not expect SFAS No. 133 to have a significant
impact on its consolidated financial statements.

FACTORS AFFECTING FUTURE RESULTS

         VARIABILITY OF OPERATING RESULTS - The Company's quarterly and annual
results of operations have varied in the past and may vary significantly in the
future due to a number of factors, including cancellation or delay of customer
orders or shipments; market acceptance of the Company's or its customers'
products; the Company's success in achieving design wins; variations in
manufacturing yields; timing of announcement and introduction of new products by
the Company and its competitors; changes in revenue and product mix; competitive
factors; changes in manufacturing capacity and variations in the utilization of
such capacity; variations in average selling prices; variations in operating
expenses; the long sales cycles associated with the Company's customer specific
products; the timing and level of product and process development costs; the
cyclicality of the semiconductor industry; the timing and level of nonrecurring
engineering ("NRE") revenues and expenses relating to customer specific
products; changes in inventory levels; and general economic conditions. Any
unfavorable changes in these or other factors could have a material adverse
effect on the Company's results of operations. For example, in June 1994,
Northern Telecom, then the Company's largest customer, requested that the
Company delay shipment of certain of its telecommunications devices to Northern
Telecom. This decision, together with a general softness of orders in the
telecommunications market, materially adversely affected the Company's revenues
and results of operations in the second quarter of 1994 and for the balance of
that year. The Company expects that its operating results will continue to
fluctuate in the future as a result of these and other factors. The Company's
expense levels are based, in part, on its expectations as to future revenue and,
as a result, net income would be disproportionately and adversely affected by a
reduction in revenue. Due to potential quarterly fluctuations in operating
results, the Company believes that quarter-to-quarter comparisons of its results
of operations are not necessarily meaningful and should not be relied upon as
indicators of future performance. Furthermore, it is likely that in some future
quarter the Company's net sales or operating results will be below the
expectations of public market securities analysts or investors. In such event,
the market price of the Company's Common Stock would likely be materially
adversely affected.

         INTEGRATION OF ACQUISITIONS - Company management frequently evaluates
the strategic opportunities available to it and may in the near-term or
long-term future pursue acquisitions of complementary products, technologies or
businesses. For example, on January 13, 1998, the Company acquired substantially
all of the assets of the Millimeter Wave Communications operation of the former
Texas Instruments' Defense Systems & Electronics Group from RTIS. Acquisition
transactions are accompanied by a number of risks, including, among other
things, the difficulty of assimilating the operations and personnel of the
acquired companies, the potential disruption of the Company's ongoing business,
the inability of management to maximize the financial and strategic position of
the Company through the successful incorporation of acquired technology and
rights into the Company's products, expenses associated with the transactions,
expenses associated with acquired in-process research and development,
additional operating expenses, the maintenance of uniform standards, controls,
procedures and policies, the impairment of relationships with employees and
customers as a result of any integration of new management personnel, and the

                                       5
<PAGE>

potential unknown liabilities associated with acquired businesses. There can be
no assurance that the Company will be successful in overcoming these risks or
any other problems encountered in connection with its acquisition of the
Millimeter Wave Communications operation or any other future acquisitions. In
addition, future acquisitions by the Company have the potential to result in
dilutive issuances of equity securities, the incurrence of additional debt, and
amortization expenses related to goodwill and other intangible assets that may
materially adversely affect the Company's results of operations.

         MANUFACTURING RISKS - The fabrication of integrated circuits,
particularly GaAs devices such as those sold by the Company, is a highly complex
and precise process. Minute impurities, difficulties in the fabrication process,
defects in the masks used to print circuits on a wafer, wafer breakage or other
factors can cause a substantial percentage of wafers to be rejected or numerous
die on each wafer to be nonfunctional. As compared to silicon technology, the
less mature stage of GaAs technology leads to somewhat greater difficulty in
circuit design and in controlling parametric variations, thereby yielding fewer
good die per wafer. In addition, the more brittle nature of GaAs wafers can
result in higher processing losses than those experienced with silicon wafers.
The Company has in the past experienced lower than expected production yields,
which have delayed product shipments and materially adversely affected the
Company's results of operations. This was experienced in the fourth quarter of
1995 and during 1996. There can be no assurance that the Company will be able to
maintain acceptable production yields in the future. Because the majority of the
Company's costs of manufacturing are relatively fixed, the number of shippable
die per wafer for a given product is critical to the Company's results of
operations. To the extent the Company does not achieve acceptable manufacturing
yields or experiences product shipment delays, its results of operations could
be materially adversely affected. In addition, the Company leases and operates
its own wafer fabrication facilities, which entails a high level of fixed costs
and which requires an adequate volume of production and sales to be profitable.
During periods of decreased demand, high fixed wafer fabrication costs could
have a material adverse effect on the Company's results of operations.

         PRODUCT QUALITY, PERFORMANCE AND RELIABILITY - The fabrication of GaAs
integrated circuits is a highly complex and precise process. The Company expects
that its customers will continue to establish demanding specifications for
quality, performance and reliability that must be met by the Company's products.
GaAs integrated circuits as complex as those offered by the Company often
encounter development delays and may contain undetected defects or failures when
first introduced or after commencement of commercial shipments. As has occurred
with most other semiconductor manufacturers, the Company has from time to time
experienced product quality, performance or reliability problems, although no
such problems have had a material adverse effect on the Company's operating
results. There can be no assurance, however, that defects or failures will not
occur in the future relating to the Company's product quality, performance and
reliability that may have a material adverse effect on the Company's results of
operations. If such failures or defects occur, the Company could experience lost
revenue, increased costs (including warranty expense and costs associated with
customer support), delays in or cancellations or rescheduling of orders or
shipments and product returns or discounts, any of which would have a material
adverse effect on the Company's business, financial condition and results of
operations.

         RELIANCE ON SIGNIFICANT CUSTOMERS; CUSTOMER CONCENTRATION - A
significant portion of the Company's revenues in each fiscal period has
historically been concentrated among a limited number of customers. In recent
periods, sales to certain of the Company's major customers as a percentage of
total revenues have fluctuated. In Fiscal 1998, Nokia and RTIS accounted for
approximately 12.0% and 11.7%, respectively of total revenues. In Fiscal 1997,
Northern Telecom accounted for approximately 12.0% of total revenues. The
Company expects that sales to a limited number of customers will continue to
account for a substantial portion of its total revenues in future periods. The
Company does not have long-term agreements with any of its customers. Customers
generally purchase the Company's products pursuant to cancelable short-term
purchase orders. The Company's business, financial condition and results of
operations have been materially adversely affected in the past by the failure of
anticipated orders to materialize and by deferrals or cancellations of orders.
If the Company were to lose a major customer or if orders by or shipments to a
major customer were to otherwise decrease or be delayed, the Company's business,
financial condition and results of operations would be materially adversely
affected.

         DEPENDENCE ON CUSTOMER SPECIFIC PRODUCTS - A substantial portion of the
Company's products are designed to address the needs of individual customers.
Frequent product introductions by systems manufacturers make the Company's
future success dependent on its ability to select customer specific development
projects which will result in sufficient production volume to enable the Company
to achieve manufacturing efficiencies. Because customer specific products are
developed for unique applications, the Company expects that some of its current
and future customer specific products may

                                       6
<PAGE>

never be produced in volume. In addition, in the event of delays in 
completing designs or the Company's failure to obtain development contracts 
from customers whose systems achieve and sustain commercial market success, 
the Company's business, financial condition and results of operations could 
be materially adversely affected.

         DEPENDENCE ON NEW PRODUCTS AND PROCESSES - The Company's future success
depends on its ability to develop and introduce in a timely manner new products
and processes which compete effectively on the basis of price and performance
and which adequately address customer requirements. The success of new product
and process introductions is dependent on several factors, including proper
selection of such products and processes, the ability to adapt to technological
changes and to support emerging and established industry standards, successful
and timely completion of product and process development and commercialization,
market acceptance of the Company's or its customers' new products, achievement
of acceptable wafer fabrication yields and the Company's ability to offer new
products at competitive prices. No assurance can be given that the Company's
product and process development efforts will be successful or that its new
products or processes will achieve market acceptance. In addition, as is
characteristic of the semiconductor industry, the average selling prices of the
Company's products have historically decreased over the products' lives and are
expected to continue to do so. To offset such decreases, the Company relies
primarily on achieving yield improvements and corresponding cost reductions in
the manufacture of existing products and on introducing new products which
incorporate advanced features and which therefore can be sold at higher average
selling prices. To the extent that such cost reductions and new product or
process introductions do not occur in a timely manner or the Company's or its
customers' products do not achieve market acceptance, the Company's business,
financial condition and results of operations could be materially adversely
affected.

         PRODUCT AND PROCESS DEVELOPMENT AND TECHNOLOGICAL CHANGE - The market
for the Company's products is characterized by frequent new product
introductions, evolving industry standards and rapid changes in product and
process technologies. Because of continual improvements in these technologies,
including those in high performance silicon where substantially more resources
are invested than in GaAs technologies, the Company believes that its future
success will depend, in part, on its ability to continue to improve its product
and process technologies and to develop in a timely manner new technologies in
order to remain competitive. In addition, the Company must adapt its products
and processes to technological changes and to support emerging and established
industry standards. There can be no assurance that the Company will be able to
improve its existing products and process technologies, develop in a timely
manner new technologies or effectively support industry standards. The failure
of the Company to improve its products and process technologies, develop new
technologies and support industry standards would have a material adverse effect
on the Company's business, financial condition and results of operations.

         EVOLVING INDUSTRY STANDARDS - The markets in which the Company and its
customers compete are characterized by rapidly changing technology, evolving
industry standards and continuous improvements in products and services. If
technologies or standards supported by the Company's or its customers' products
become obsolete or fail to gain widespread commercial acceptance, the Company's
business, financial condition and results of operations may be materially
adversely affected. In addition, the increasing demand for wireless
communications has exerted pressure on regulatory bodies worldwide to adopt new
standards for such products, generally following extensive investigation of and
deliberation over competing technologies. The delays inherent in the regulatory
approval process may in the future cause the cancellation, postponement or
rescheduling of the installation of communications systems by the Company's
customers. These delays have in the past had and may in the future have a
material adverse effect on the sale of products by the Company and on its
business, financial condition and results of operations.

         COMPETITION - The semiconductor industry is intensely competitive and
is characterized by rapid technological change, rapid product obsolescence and
price erosion. Currently, the Company competes primarily with manufacturers of
high performance silicon semiconductors such as AMCC, Motorola and Philips and
with manufacturers of GaAs semiconductors such as Anadigics, Vitesse, RF
Microdevices and Raytheon. The Company expects increased competition both from
existing competitors and from a number of companies which may enter the GaAs
integrated circuit market, as well as future competition from companies which
may offer new or emerging technologies such as silicon germanium. Most of the
Company's current and potential competitors have significantly greater
financial, technical, manufacturing and marketing resources than the Company.
Additionally, manufacturers of high performance silicon semiconductors have
achieved greater market acceptance of their existing products and technologies
in certain applications. There can be no assurance that the Company will not
face increased competition or that the Company will be able to compete
successfully in the future. The

                                       7
<PAGE>

failure of the Company to successfully compete in its markets would have a 
material adverse effect on the Company's business, financial condition and 
results of operations.

         ADOPTION OF GaAs COMPONENTS BY SYSTEMS MANUFACTURERS - Silicon
semiconductor technologies are the dominant process technologies for integrated
circuits and these technologies continue to improve in performance. TriQuint's
prospective customers are frequently systems designers and manufacturers who are
utilizing such silicon technologies in their existing systems and who are
evaluating GaAs integrated circuits for use in their next generation high
performance systems. Customers may be reluctant to adopt TriQuint's products
because of perceived risks relating to GaAs technology generally. Such perceived
risks include the unfamiliarity of designing systems with GaAs products as
compared with silicon products, concerns related to manufacturing costs and
yields, novel design and unfamiliar manufacturing processes and uncertainties
about the relative cost effectiveness of the Company's products compared to high
performance silicon integrated circuits. In addition, customers may be reluctant
to rely on a smaller company such as TriQuint for critical components. There can
be no assurance that additional systems manufacturers will design the Company's
products into their respective systems, that the companies that have utilized
the Company's products will continue to do so in the future or that GaAs
technology will achieve widespread market acceptance. Should the Company's GaAs
products fail to achieve market acceptance or be utilized in manufacturers'
systems, the Company's business, financial condition and results of operations
would be materially adversely affected.

         GaAs COMPONENTS MORE COSTLY TO PRODUCE - The production of GaAs
integrated circuits has been and continues to be more costly than the production
of silicon devices. This cost differential relates primarily to higher costs of
the raw wafer material, lower production yields associated with the relatively
immature GaAs technology and higher unit costs associated with lower production
volumes. Although the Company has reduced unit production costs by increasing
wafer fabrication yields, by achieving higher volumes and by obtaining lower raw
wafer costs, there can be no assurance that the Company will be able to continue
to decrease production costs. In addition, the Company believes that its costs
of producing GaAs integrated circuits will continue to exceed the costs
associated with the production of silicon devices. As a result, the Company must
offer devices which provide superior performance to that of silicon-based
devices such that the perceived price/performance of its products is
competitive. There can be no assurance that the Company can continue to identify
markets which require performance superior to that offered by silicon solutions,
or that the Company will continue to offer products which provide sufficiently
superior performance to offset the cost differential.

         MANAGEMENT OF GROWTH - The growth in the Company's business has placed,
and is expected to continue to place, a significant strain on the Company's
personnel, management and other resources. The Company's ability to manage any
future growth effectively will require it to attract, train, motivate, manage
and retain new employees successfully, to integrate new employees into its
overall operations and in particular its manufacturing operations, and to
continue to improve its operational, financial and management information
systems.

         DEPENDENCE ON KEY PERSONNEL - The Company's future success depends in
large part on the continued service of its key technical, marketing and
management personnel and on its ability to continue to identify, attract and
retain qualified technical and management personnel, particularly highly skilled
design, process and test engineers involved in the manufacture of existing
products and the development of new products and processes. Furthermore, there
may be only a limited number of persons in the Company's geographic area with
the requisite skills to serve in these positions. There are many other
semiconductor companies located in the Company's geographic area and it may
become increasingly difficult for the Company to attract and retain such
personnel. The competition for such personnel is intense, and the loss of key
employees could have a material adverse effect on the Company.

         SOLE SOURCES OF MATERIALS AND SERVICES - The Company currently procures
certain components and services for its products from single sources, such as
ceramic packages from Kyocera. The Company purchases these components and
services on a purchase order basis, does not carry significant inventories of
these components and does not have any long-term supply contracts with its sole
source vendors. If the Company were to change any of its sole source vendors,
the Company would be required to requalify the components with each new vendor.
Requalification could prevent or delay product shipments which could materially
adversely affect the Company's results of operations. In addition, the Company's
reliance on sole source vendors involves several risks, including reduced
control over the price, timely delivery, reliability and quality of the
components. Any inability of the Company to obtain timely deliveries of
components of acceptable quality in required

                                       8
<PAGE>

quantities or any increases in the prices of components for which the Company 
does not have alternative sources could materially adversely affect the 
Company's business, financial condition and results of operations.

         CYCLICALITY OF THE SEMICONDUCTOR INDUSTRY - The semiconductor industry
has historically been characterized by wide fluctuations in product supply and
demand. From time to time, the industry has also experienced significant
downturns, often in connection with, or in anticipation of, major additions of
wafer fabrication capacity, maturing product cycles or declines in general
economic conditions. These downturns have been characterized by diminished
product demand, production overcapacity and subsequent accelerated price
erosion, and in some cases have lasted for extended periods of time. The
Company's business has in the past been and could in the future be materially
adversely affected by industry-wide fluctuations. The Company's continued
success will depend in large part on the continued growth of the semiconductor
industry in general and its customers' markets in particular. No assurance can
be given that the Company's business, financial condition and results of
operations will not be materially adversely affected in the future by cyclical
conditions in the semiconductor industry or in any of the markets served by the
Company's products.

         PROPRIETARY TECHNOLOGY - The Company's ability to compete is affected
by its ability to protect its proprietary information. The Company relies on a
combination of patents, trademarks, copyrights, trade secret laws,
confidentiality procedures and licensing arrangements to protect its
intellectual property rights. The Company currently has patents granted and
pending in the United States and in foreign countries and intends to seek
further international and United States patents on its technology. There can be
no assurance that patents will issue from any of the Company's pending
applications or applications in preparation or that patents will be issued in
all countries where the Company's products can be sold or that any claims
allowed from pending applications or applications in preparation will be of
sufficient scope or strength to provide meaningful protection or any commercial
advantage to the Company. Also, competitors of the Company may be able to design
around the Company's patents. The laws of certain foreign countries in which the
Company's products are or may be developed, manufactured or sold, including
various countries in Asia, may not protect the Company's products or
intellectual property rights to the same extent as do the laws of the United
States, increasing the possibility of piracy of the Company's technology and
products. Although the Company intends to vigorously defend its intellectual
property rights, there can be no assurance that the steps taken by the Company
to protect its proprietary information will be adequate to prevent
misappropriation of its technology or that the Company's competitors will not
independently develop technologies that are substantially equivalent or superior
to the Company's technology.

         RISK OF THIRD PARTY CLAIMS OF INFRINGEMENT - The semiconductor industry
is characterized by vigorous protection and pursuit of intellectual property
rights or positions, which have resulted in significant and often protracted and
expensive litigation. If it is necessary or desirable, the Company may seek
licenses under such patents or other intellectual property rights. However,
there can be no assurance that licenses will be offered or that the terms of any
offered licenses will be acceptable to the Company. The failure to obtain a
license from a third party for technology used by the Company could cause the
Company to incur substantial liabilities and to suspend the manufacture of
products. Furthermore, the Company may initiate claims or litigation against
third parties for infringement of the Company's proprietary rights or to
establish the validity of the Company's proprietary rights. Litigation by or
against the Company could result in significant expense to the Company and
divert the efforts of the Company's technical and management personnel, whether
or not such litigation results in a favorable determination for the Company. In
the event of an adverse result in any such litigation, the Company could be
required to pay substantial damages, indemnify its customers, cease the
manufacture, use and sale of infringing products, expend significant resources
to develop non-infringing technology, discontinue the use of certain processes
or obtain licenses to the infringing technology. There can be no assurance that
the Company would be successful in such development or that such licenses would
be available on reasonable terms, or at all, and any such development or license
could require expenditures of substantial time and other resources by the
Company. In the event that any third party makes a successful claim against the
Company or its customers and a license is not made available to the Company on
commercially reasonable terms, the Company's business, financial condition and
results of operations would be materially adversely affected.

         On February 26, 1999, a lawsuit was filed against 88 firms, including
the Company, in the United States District Court for the District of Arizona.
The suit alleges that the defendants infringe upon certain patents held by The
Lemelson Medical, Education and Research Foundation, Limited Partnership.
Although the Company believes that the suit is without merit and intends to
vigorously defend itself against the charges, there can be no assurance that
such defense will be successful. Moreover, such litigation may require
expenditures of substantial time and money and could distract management from
the Company's day-to-day operations.

                                       9
<PAGE>

         ENVIRONMENTAL REGULATIONS - The Company is subject to a variety of
federal, state and local laws, rules and regulations related to the discharge or
disposal of toxic, volatile or other hazardous chemicals used in its
manufacturing process. The failure to comply with present or future regulations
could result in fines being imposed on the Company, suspension of production or
a cessation of operations. Such regulations could require the Company to acquire
significant equipment or to incur substantial other expenses to comply with
environmental regulations. Any failure by the Company, or by TI with respect to
the Company's Texas facility, to control the use of, or to adequately restrict
the discharge of, hazardous substances could subject the Company to future
liabilities or could cause its manufacturing operations to be suspended,
resulting in a material adverse effect on the Company's business, financial
condition and results of operations.

         RISKS ASSOCIATED WITH INTERNATIONAL SALES - Sales outside of the United
States were $26.8 million, $24.3 million, and $18.1 million, in Fiscal 1998,
Fiscal 1997, and Fiscal 1996, respectively. These sales involve a number of
inherent risks, including imposition of government controls, currency exchange
fluctuations, potential insolvency of international distributors and
representatives, reduced protection for intellectual property rights in some
countries, the impact of recessionary environments in economies outside the
United States, political instability and generally longer receivables collection
periods, as well as tariffs and other trade barriers. In addition, due to the
technological advantage provided by GaAs in many military applications, all of
the Company's sales outside of North America must be licensed by the Office of
Export Administration of the U.S. Department of Commerce. Although the Company
has not experienced significant difficulty in obtaining these licenses, failure
to obtain such licenses or delays in obtaining such licenses in the future could
have a material adverse effect on the Company's results of operations.
Furthermore, because substantially all of the Company's foreign sales are
denominated in U.S. dollars, increases in the value of the dollar would increase
the price in local currencies of the Company's products in foreign markets and
make the Company's products less price competitive. There can be no assurance
that these factors will not have a material adverse effect on the Company's
future international sales and, consequently, on the Company's business,
financial condition and results of operations.

         DEPENDENCE ON ASSEMBLY CONTRACTORS - The Company's finished GaAs wafers
are assembled and packaged by ten independent subcontractors, seven of which are
located outside of the United States. Any prolonged work stoppages or other
failure of these contractors to supply finished products would have a material
adverse effect on the Company's business, financial condition and results of
operations.

         YEAR 2000 RISKS - Many information technology ("IT") hardware and
software systems, as well as other non-IT equipment utilizing microprocessors,
can accept only two digit entries in the date code field. To operate using dates
after December 31, 1999, the date code fields will need to accept four digit
entries to distinguish twenty-first century dates from twentieth century dates.
This is commonly referred to as the "Year 2000" or "Y2K" issue. The Company has
initiated a comprehensive Y2K audit program, which consists of a six step plan
to inventory and correct any non-compliant systems. These six steps are:
inventory, assessment, planning, remediation, testing and implementation. The
audit program encompasses a review of IT systems used in the Company's internal
business as well as non-IT systems such as manufacturing systems and building
systems. It also includes an audit and evaluation of third party vendors,
manufacturers and suppliers. The Company has completed the audit program through
the planning phase and is currently in the remediation phase, for both IT and
non-IT systems as well as third-party vendors, manufacturers and suppliers.
Because of the existence of numerous systems and related components within the
Company and the interdependency of these systems, it is possible that certain
systems at the Company, or systems at entities that provide services or goods
for the Company, may fail to operate in the Year 2000. Although it is not
currently anticipated, the inability of the Company to become Y2K compliant on a
timely basis or the failure of a system at the Company or at an entity that
provides services or goods to the Company may have a material impact on future
operating results or financial condition.

LIQUIDITY AND CAPITAL RESOURCES

         The Company completed a follow-on public offering in September 1995
raising approximately $48.1 million, net of offering expenses. In December 1993
and January 1994, the Company completed its initial public offering raising
approximately $16.7 million, net of offering expenses. In addition, the Company
has funded its operations to date through other sales of equity, bank borrowing,
equipment leases, and cash flow from operations. As of December 31, 1998, the
Company had working capital of approximately $44.5 million, including $26.1
million in cash, cash equivalents, and

                                       10
<PAGE>

investments. The Company has a $10.0 million unsecured revolving line of 
credit with a financial institution. Restrictive covenants included in the 
line of credit require the Company to maintain (i) a total liability to 
tangible net worth ratio of not more than 0.75 to 1.00, (ii) a current ratio 
of not less than 1.75 to 1.00 and (iii) minimum tangible net worth greater 
than $79.7 million and (iv) cash and investments, including restricted 
investments, greater than $45.0 million. As of December 31, 1998 the Company 
was in compliance with the restrictive covenants contained in this line of 
credit. However, there can be no assurance that the Company will continue to 
be in compliance with these covenants as of any subsequent date.

         In May 1996, the Company entered into a five year synthetic lease
through a Participation Agreement (the "Agreement") with Wolverine Leasing Corp.
("Wolverine"), Matisse holding Company ("Matisse") and United States National
Bank of Oregon ("USNB"). The lease provides for the construction and occupancy
of the Company's new headquarters and wafer fabrication facility in Hillsboro
under an operating lease from Wolverine and provides the Company with an option
to purchase the property or renew its lease for an additional five years.
Pursuant to the terms of the Agreement, USNB and Matisse made loans to Wolverine
who in turn advanced the funds to the Company for the construction of the
Hillsboro facility and other costs and expenses associated therewith. The loan
from USNB is collateralized by investment securities pledged by the Company.
Such investment securities are classified on the Company's balance sheet as
restricted securities. In addition, restrictive covenants in the Agreement
require the Company to maintain (i) a total liability to tangible net worth
ration of not more than 0.75 to 1.00, (ii) minimum tangible net worth greater
than $50.0 million and (iii) cash and liquid investment securities, including
restricted securities, greater than $45.0 million. As of December 31, 1998, the
Company was in compliance with the covenants described above. However, there can
be no assurance that the Company will continue to be in compliance with these
covenants as of any subsequent date.

         In November 1997, the Company entered into a $1.5 million lease for
additional land adjacent to its Hillsboro facility. Pursuant to the terms of
that agreement, USNB provided loans to Matisse to purchase the land, who in turn
leased it to the Company under a renewable one year lease agreement. The loan
from USNB is partially collateralized by a guarantee from the Company. The
agreement contains restrictive covenants substantially the same as those
contained in the Company's line of credit. As of December 31, 1998 the Company
was in compliance with the terms of the agreement. However, there can be no
assurance that the Company will continue to be in compliance with these terms as
of any subsequent date.

         In January 1998, the Company acquired the Millimeter Wave
Communications operation of the former Texas Instruments' Defense Systems &
Electronics Group from RTIS. Pursuant to an Asset Purchase Agreement with RTIS,
the Company acquired the Millimeter Wave Communications operation for
approximately $19.5 million in cash and 844,613 shares of TriQuint Common Stock
valued at approximately $19.5 million for a total purchase consideration of
approximately $39 million. The cash portion of the purchase price was financed
through an operating lease arrangement involving certain assets pursuant to the
Agreement.

The following table presents a summary of the Company's cash flows ( IN

</TABLE>

         Net cash provided by operating activities in Fiscal 1998 and Fiscal
1997 of $10.2 million and $4.2 million, respectively, related primarily to
profitable operations before special charges. Net cash provided by operating
activities in Fiscal 1996 was $5.4 million.

         Cash used by investing activities in Fiscal 1998 of $10.9 million was
primarily the result of the purchase of $68.0 million of investments and capital
expenditures of $5.6 million. This cash used by investing activities was
partially offset by the sale and/or maturity of $62.3 million of investments.
Cash provided by investing activities in Fiscal 1997 relates

                                       11
<PAGE>

primarily to the net sale and/or maturity of investment securities of $3.9 
million and capital expenditures of $1.4 million. Cash used by investing 
activities in Fiscal 1996 relates primarily to the net purchase of 
investments of $21.9 million and capital expenditures of $4.1 million. The 
Company will continue to monitor interest rates to enhance return on its cash 
and short term investments while maintaining a high degree of liquidity.

         Cash used by financing activities of $3.5 million, $1.6 million and
$1.8 million in Fiscal 1998, Fiscal 1997, and Fiscal 1996, respectively, is
primarily the result of net principal payments under capital lease obligations
and installment notes, partially offset by the proceeds of the issuance of
common stock upon option exercises.

         For Fiscal 1998, the Company established approximately $2.2 million in
new capital lease equipment financing. The Company's balances of current
installments of capital lease and installment note obligations of $4.9 million
and capital lease and installment note obligations, less current installments,
of $9.4 million as of December 31,1998 are related to the financing of machinery
and equipment through equipment financing obligations. The Company expects to
make continued investments in its capital equipment, including manufacturing and
test equipment and computer hardware and software, in order to enhance its
technology and competitive position. The Company expects to make total capital
expenditures of approximately $15 million over the next twelve months.

         The Company believes that its current cash and cash equivalent
balances, together with cash anticipated to be generated from operations and
anticipated financing arrangements, will satisfy the Company's projected working
capital and capital expenditure requirements, at a minimum, through the end of
1999. However, the Company may be required to finance any additional
requirements through additional equity, debt financings, or credit facilities.
There can be no assurance that such additional financings or credit facilities
will be available, or if available, that they will be on satisfactory terms.

YEAR 2000 COMPLIANCE

         Many information technology ("IT") hardware and software systems, as 
well as other non-IT equipment utilizing microprocessors, can accept only two 
digit entries in the date code field. To operate using dates after December 
31, 1999, the date code fields will need to accept four digit entries to 
distinguish twenty-first century dates from twentieth century dates. This is 
commonly referred to as the "Year 2000" or "Y2K" issue. STATE OF READINESS - 
The Company has initiated a comprehensive Y2K audit program, which consists 
of a six step plan to inventory and correct any non-compliant systems. These 
six steps are: inventory, assessment, planning, remediation, testing and 
implementation. The audit program encompasses a review of IT systems used in 
the Company's internal business as well as non-IT systems such as 
manufacturing systems and building systems. It also includes an audit and 
evaluation of third party vendors, manufacturers and suppliers. The Company 
has completed the audit program through the planning phase and is currently 
in the remediation phase, for both IT and non-IT systems as well as 
third-party vendors, manufacturers and suppliers. The Company's products have 
no specific date functions or date dependencies and will operate according to 
specifications through the Year 2000 date rollover and thereafter. COSTS - 
The Company does not believe that the historical or anticipated costs of 
remediation have had, or will have, a material effect on the Company's 
financial condition or results of operations. For IT systems and most non-IT 
systems, the costs of remediation have been or will be encompassed in the 
normal anticipated expenditures for maintenance contracts and version 
upgrades. Total incremental cost of remediation is estimated at $150,000. 
RISKS, CONTINGENCY PLAN AND REASONABLY LIKELY WORST CASE SCENARIO - While the 
Company is heavily reliant upon its computer systems, software applications 
and other electronics containing date-sensitive, embedded technology as part 
of its business operations, such components upon which the Company primarily 
relies were developed with current state-of-the-art technology and, 
accordingly, the Company reasonably anticipates that its six-step audit and 
remediation program will demonstrate that many of its high-priority systems 
do not present material Y2K compliance issues. For computer systems, software 
applications and other electronics containing date-sensitive embedded 
technology that have met the Company's desired level of Y2K readiness, the 
Company will use its existing contingency plans to mitigate or eliminate 
problems it may experience if an unanticipated system failure were to occur. 
For components that have not met the Company's desired level of readiness 
specific contingency plans will be developed to determine the actions the 
Company would take if such a component failed. At the present time, the 
Company has not developed a most reasonably likely worst case scenario for 
failure to achieve Y2K compliance. The Company will be better able to develop 
such a scenario as it moves through the testing phase of the audit program 
and as it continues to monitor progress of critical third-party vendors, 
manufacturers and suppliers. Because of the existence of numerous systems and 
related components within the 

                                       12

Company and the interdependency of these systems, it is possible that certain 
systems at the Company, or systems at entities that provide services or goods 
for the Company, may fail to operate in the Year 2000. Although it is not 
currently anticipated, the inability of the Company to become Y2K compliant 
on a timely basis or the failure of a system at the Company or at an entity 
that provides services or goods to the Company may have a material impact on 
future operating results or financial condition.

                       INDEPENDENT AUDITORS' REPORT



The Board of Directors and Shareholders
TriQuint Semiconductor, Inc.:


We have audited the accompanying consolidated balance sheets of TriQuint 
Semiconductor, Inc. and subsidiary as of December 31, 1998 and 1997, and the 
related consolidated statements of operations, shareholders' equity, and cash 
flows for each of the years in the three-year 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 consolidated financial 
statements. An audit also includes assessing the accounting principles used 
and significant estimates made by management, as well as evaluating the 
overall financial statement presentation. We believe that our audits provide 
a reasonable basis for our opinion. 

In our opinion, the consolidated financial statements referred to above 
present fairly, in all material respects, the financial position of TriQuint 
Semiconductor, Inc. and subsidiary as of December 31, 1998 and 1997, and the 
results of its operations, and its cash flows for each of the years in the 
three-year period ended December 31, 1998 in conformity with generally 
accepted accounting principles.

                    Notes to Consolidated Financial Statements

                             December 31, 1998 and 1997

                       (In thousands, except share information)


(1)    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES


       (a)    DESCRIPTION OF THE COMPANY

              TriQuint Semiconductor, Inc. (the Company) is engaged in the
              design, development, manufacture and sale of a broad range of high
              performance analog and mixed signal integrated circuits for the
              wireless communications, telecommunications, data communication
              and millimeter wave markets. The Company utilizes its proprietary 
              gallium arsenide (GaAs) technology to manufacture its products.


       (b)    PRINCIPLES OF CONSOLIDATION

              The accompanying consolidated financial statements include the
              accounts of the Company and its wholly-owned subsidiary. All
              significant inter-company accounts and transactions are eliminated
              in consolidation.


       (c)    MANAGEMENT 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.


       (d)    REVENUE RECOGNITION

              Standard product revenue is recognized upon shipment of product.
              The Company recognizes revenue on foundry and customer-specific
              products based on certain design, manufacturing and other
              milestones. The Company recognizes revenue on cost plus contracts
              as work is performed.


       (e)    CASH EQUIVALENTS

              The Company considers all highly liquid debt and equity
              instruments purchased with an original maturity of three months or
              less to be cash equivalents.

                                       6                             (Continued)

                    Notes to Consolidated Financial Statements

                             December 31, 1998 and 1997

                       (In thousands, except share information)

       (f)    INVESTMENTS

              The Company's investments, both restricted and unrestricted, are
              comprised of medium term corporate notes, commercial paper and
              market auction preferred stock and have been classified as
              available-for-sale securities in accordance with Statement of
              Financial Accounting Standards (SFAS) No. 115, ACCOUNTING FOR
              CERTAIN INVESTMENTS IN DEBT AND EQUITY SECURITIES at December 31,
              1998 and 1997. The carrying value of available-for-sale securities
              approximates fair value at December 31, 1998 and 1997.


       (g)    TRADE ACCOUNTS RECEIVABLE

              Trade accounts receivable are shown net of allowance for doubtful
              accounts of $262 and $196 at December 31, 1998 and 1997, 
              respectively.


       (h)    INVENTORIES

              Inventories are stated at the lower of cost (approximates actual
              cost on a first-in, first-out basis) or market (net realizable
              value). Inventories are shown net of a valuation reserve of $2,422
              and $1,324 at December 31, 1998 and 1997, respectively.


       (i)    PROPERTY, PLANT AND EQUIPMENT

              Property, plant and equipment are recorded at cost. Machinery and
              equipment under capital leases are stated at the lower of the
              present value of the minimum lease payments at the beginning of
              the lease term or the fair value of the leased assets at the
              inception of the lease.

              Depreciation is provided using the straight-line method over their
              estimated useful lives, which are as follows: five years for
              machinery and equipment, furniture and fixtures and computer
              equipment; three to seven years for leasehold improvements; and
              ten years for buildings. Leasehold improvements are amortized over
              the shorter of the estimated life of the asset or the term of the
              related lease. Depreciation begins on assets in process at the
              time the related assets are placed in service. Maintenance and
              repairs are expensed as incurred.


       (j)    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 revenues on non-recurring
              engineering services billed to customers are classified as
              research, development and engineering expense. Additionally,
              certain related contract engineering costs are also included in
              research, development and engineering expense.

                                       7                             (Continued)

                    Notes to Consolidated Financial Statements

                             December 31, 1998 and 1997

                       (In thousands, except share information)

       (k)    COMPREHENSIVE INCOME

              Effective January 1, 1998, the Company adopted the provisions of
              SFAS No. 130, REPORTING COMPREHENSIVE INCOME. The objective of
              SFAS No. 130 is to report all changes in equity that result from
              transactions and economic events other than transactions with
              owners. There is no difference between net income (loss) and
              comprehensive income (loss) for the years ended December 31, 1998,
              1997 and 1996.


       (l)    NET INCOME PER SHARE

              The Company has adopted SFAS No. 128, EARNINGS PER SHARE. SFAS No.
              128 requires presentation of basic and diluted net income per
              share. Basic net income per share is net income available to
              common shareholders divided by the weighted-average number of
              common shares outstanding. Diluted net income per share is similar
              to basic except that the denominator includes potential common
              shares that, had they been issued, would have had a dilutive
              effect. The reconciliation of shares used to calculate basic and
              diluted income per share consists of the following as of December
              31:

</TABLE>

              Common stock equivalents related to stock options and warrants 
totaling 442,831, 37,572 and 263,984 are anti-dilutive and, therefore, were 
not included in the diluted net loss per share calculation for the years 
ended December 31, 1998, 1997 and 1996, respectively.

       (m)    INCOME TAXES

              The Company accounts for income taxes under the asset and
              liability method. Under the asset and liability method, deferred
              tax assets and liabilities are recognized for the future tax
              consequences attributable to differences between the financial
              statement carrying amounts of existing assets and liabilities and
              their respective tax bases. Deferred tax assets and liabilities
              are measured using enacted tax rates expected to apply to taxable
              income in the years in which those temporary differences are
              expected to be recovered or settled. The effect on deferred tax
              assets and liabilities of a change in tax rates is recognized in
              income in the period that includes the enactment date. Valuation
              allowances are established when necessary to reduce deferred tax
              assets to the amounts expected to be realized.


       (n)    FINANCIAL INSTRUMENTS

              The carrying amount of cash equivalents, investments, trade
              accounts receivable and accounts payable approximate fair value
              because of the short-term nature of these instruments. The fair
              value of long-term borrowings were estimated by discounting the
              future cash flows using market interest rates and does not differ
              significantly from that reflected in the accompanying financial
              statements.

              Fair value estimates are made at a specific point in time, based
              on relevant market information about the financial instrument.
              These estimates are subjective in nature and involve uncertainties
              and matters of significant judgment and therefore cannot be
              determined with precision. Changes in assumptions could
              significantly affect the estimates.


       (o)    STOCK OPTION PLANS

              The Company accounts for its stock option plans in accordance with
              the provisions of Accounting Principles Board (APB) Opinion No.
              25, ACCOUNTING FOR STOCK ISSUED TO EMPLOYEES, and related
              interpretations. As such, compensation expense would be recorded
              on the date of grant only if the current market price of the
              underlying stock exceeded the exercise price. The Company also
              applies SFAS No. 123, ACCOUNTING FOR STOCK-BASED COMPENSATION,
              which allows entities to continue to apply the provisions of APB
              Opinion No. 25 and provide pro forma net income and pro forma
              earnings per share disclosures for employee stock option grants as
              if the fair-value-based method defined in SFAS No. 123 had been
              applied.


       (p)    RECLASSIFICATIONS

               Certain reclassifications have been made to the 1996 and 1997
               statements to conform with the 1998 presentation.

(2)    MILLIMETER WAVE COMMUNICATIONS ACQUISITION

       On January 13, 1998, the Company acquired substantially all of the assets
       of the Millimeter Wave Communications operation of the former Texas
       Instruments' Defense Systems and Electronics Group from Raytheon TI
       Systems, Inc. (RTIS), a Delaware corporation and a wholly owned
       subsidiary of Raytheon company. The Millimeter Wave Communications
       business designs, develops, produces and sells advanced GaAs MMIC
       products which are used in defense and commercial applications. Pursuant
       to an Asset Purchase Agreement (the Agreement) with RTIS, the Company
       acquired the Millimeter Wave Communications business for approximately
       $19,500 in cash and 844,613 shares of the Company's common stock valued
       at approximately $19,500 for total purchase consideration of
       approximately $39,000. The cash portion of the purchase price was
       financed through an operating lease arrangement involving certain assets
       pursuant to the Agreement.

       The purchase accounting allocations resulted in charges for in-process
       research and development of $8,820 recorded as a special charge, and
       other intangibles of approximately $2,132. These other intangible assets,
       classified as other non-current assets, are amortized on a straight-line 
       basis over 7 years, and are shown net of related accumulated amortization

                    Notes to Consolidated Financial Statements

                             December 31, 1998 and 1997

                       (In thousands, except share information)

       The Company entered into a five year agreement to construct and lease an
       office building and fabrication facility in Hillsboro, Oregon (Hillsboro
       Facility) in 1996. Rent obligations began in February of 1997 and are
       equal to the lessor's debt service costs. At the end of the lease term,
       the Company may (i) renew the lease for up to five additional years, (ii)
       exercise its purchase option, or (iii) cause the leased assets to be sold
       to a third party whereby the Company guarantees up to a maximum of 85% of
       the original cost. The future minimum lease payments stated above exclude
       any payments required at the end of the lease term.

       As part of the above lease, the Company restricted $40,163 of its
       securities as collateral for specified obligations of the lessor under
       the lease. These securities will be restricted as to withdrawal and will
       be managed by the Company subject to certain limitations under its
       investment policy. In addition, the Company must maintain a minimum
       consolidated tangible net worth of $50 million total liabilities to net
       worth ratio equal to or less than .75 to 1 and maintain cash and liquid
       investments, including restricted investments, greater than $45 million.

       In November 1997, the Company entered into a $1,500 lease agreement for
       additional property adjacent to its Hillsboro Facility. Pursuant to the
       terms of that agreement, the transaction is partially collateralized by a
       guarantee from the Company.

       In 1997 and 1998, the Company entered into two-year agreements to lease
       equipment in Dallas, Texas and Hillsboro, Oregon. Rent obligations are
       equal to the lessor's debt service costs and will expire at the end of
       the initial lease terms. At the end of the lease terms, the Company may
       (i) renew the leases for up to three additional years, (ii) exercise its
       purchase options, or (iii) cause the equipment to be sold to a third
       party whereby the Company guarantees residual values to the lessor. The
       future minimum lease payments stated above exclude any payments required
       at the end of the lease term. The Company intends to renew the leases for
       three additional years at the end of each initial lease term.


(5)    DEBT

       The Company has a line of credit agreement for general corporate purposes
       with a commercial bank. The agreement is unsecured, and provides for
       aggregate borrowings of $10,000. The interest rate is based on three
       pricing options (LIBOR, bankers' acceptance, and prime) plus an interest
       rate spread which is determined quarterly based on the Company's ratio of
       total liabilities to tangible net worth. Interest is payable periodically

(6)    SHAREHOLDERS' EQUITY


       (a)    STOCK OPTION PLANS AND EMPLOYEE STOCK PURCHASE PLANS

              Under the 1987 and 1996 Stock Incentive Programs and the 1998
              Nonstatutory Stock Option Plan (the Plans), the Company has
              authorized the issuance of 1,897,768, 1,250,000 and 500,000 common
              shares, respectively, of which a total of 302,881 shares are
              available to grant. The Plans provide for the grant of incentive
              stock options to officers and other employees of the Company or
              any parent or subsidiary, and non-qualified stock options to
              officers and other employees of the Company, directors, and
              consultants of the Company. Subject to the discretion of the Board
              of Directors, options granted under the Plans generally vest and
              become exercisable at the rate of 28% at the end of the first
              year, and thereafter at a rate of 2% per month and have a ten-year
              term.

              The exercise price of all incentive stock options granted under
              the Plans must be at least equal to the fair market value of the
              shares on the date of grant. With respect to any participant who
              owns stock possessing more than 10% of the voting rights of the
              Company's outstanding capital stock, the exercise price of any
              incentive stock option granted must equal at least 110% of the
              fair market value on the grant date. The exercise price of all
              non-statutory stock options granted under the Plans must be at
              least 50% of the fair market value of the common stock on the date
              of grant. However, it is the Company's practice to issue options
              at fair market value. The terms of all options granted under the
              Plans may not exceed ten years.

              The fair value of each stock based compensation award is estimated
              on the date of grant using the Black Scholes option-pricing model
              assuming no dividend yield and the following weighted-average
              assumptions for stock based compensation awards during the years
              ended December 31:

              The weighted average fair value of stock based compensation awards

              The Company applies APB Opinion No. 25 in accounting for its Plans
              and, accordingly, no compensation cost has been recognized for its
              stock based compensation awards in the financial statements. Had
              the Company determined compensation cost based on the fair value
              at the date of grant for its stock based compensation awards under
              SFAS No. 123, the Company's net income would have been reduced to
              the pro forma amounts indicated below:

              Pro forma net income (loss) reflects only stock based compensation
              awards granted in 1998, 1997 and 1996. Therefore, the full impact
              of calculating compensation cost for stock based compensation
              awards under SFAS No. 123 is not reflected in the pro forma net
              income amounts presented above because compensation cost is
              reflected over the options' vesting period of 4 years and
              compensation cost for options granted prior to January 1, 1996 is
              not considered and additional stock based compensation awards are
              anticipated in future years.

                       (In thousands, except share information)


              In September 1998, the Compensation Committee of the Board of
              Directors adopted a resolution to offer employees holding stock
              options for 883,212 shares the opportunity to exchange their
              existing stock options for new stock options. The exchange allowed
              employees to receive options for the same number of shares at
              $16.125 per share, which exceeded the market price during the
              employee decision period, instead of an average original exercise
              price of $22.12. The new options vest over one to four years. The
              offer was made because the Board of Directors believe the lower
              priced options provide greater retention advantage and incentive.
              Options for directors and officers were not repriced. Option
              holders elected to exchange options covering 704,627 shares, which
              is included as both options granted and canceled during 1998 in
              the preceding table.

              The following table summarizes information concerning stock
              options outstanding and exercisable at December 31, 1998:

              Under the 1992 and 1998 Employee Stock Purchase Plans (the
              Purchase Plans), the Company has authorized the issuance of
              600,000 common shares, of which 418,094 are available at December
              31, 1998. The Purchase Plans allow eligible employees to purchase
              the Company's common stock through payroll deductions, which may
              not exceed 15% of an employee's base compensation, not to exceed
              $25 per year, including commissions, bonuses and overtime, at a
              price equal to 85% of the lower of the fair value at the beginning
              or end of each enrollment period.

       (b)    WARRANTS

              On August 31, 1993, the Company issued a warrant to purchase of up
              to 125,000 shares of common stock at $24.00 per share and is
              exercisable through August 2000. On December 19, 1994, the Company
              issued an additional warrant to purchase of up to 75,000 shares of
              common stock at $24.00 per share and is exercisable through
              December 2001.


       (c)    PREFERRED SHARES RIGHTS AGREEMENT

              On June 30, 1998, the Company adopted a Preferred Shares Rights
              Agreement (the "Agreement"). Pursuant to the Agreement, rights
              were distributed as a dividend at the rate of one right for each
              share of TriQuint common stock, par value $0.001 per share of the
              Company held by stockholders of record as of the close of business
              on July 24, 1998. The rights will expire on June 29, 2008, unless
              redeemed or exchanged. Under the Agreement, each right initially
              will entitle the registered holder to buy one unit of a share of
              preferred stock for $125.00. The rights will become exercisable
              only if a person or group (other than stockholders currently
              owning 15% of the Company's common stock) acquires beneficial
              ownership of 15% or more of Company's common stock, or commences a
              tender offer or exchange offer upon consummation of which such
              person or group would beneficially own 15% or more of the
              Company's common stock.

</TABLE>

       The valuation allowance for deferred tax assets as of January 1, 1996 was
       $11,712. The net change in total valuation allowance for the years ended
       December 31, 1998, 1997 and 1996 was an increase (decrease) of $2,207,
       $(517) and $(1,060), respectively. Approximately $5,151 of the valuation
       allowance for deferred tax assets will be credited directly to
       shareholders' equity in the event tax benefits of net operating losses
       that resulted from stock option exercises are subsequently recognized.

       At December 31, 1998, the Company had approximately $45,700 of net
       operating loss carryforwards to offset against future income for federal
       income tax purposes which expire from 2003 through 2018, and $22,003 for
       Oregon state income tax purposes which expire in years 2006 through 2013.

       The Company's ability to use its net operating loss carryforwards to
       offset future taxable income is subject to annual restrictions contained
       in the United States Internal Revenue Code of 1986, as amended (the
       Code). These restrictions act to limit the Company's future use of its
       net operating losses following certain substantial stock ownership
       changes enumerated in the Code and referred to hereinafter as an
       "ownership change."

                    Notes to Consolidated Financial Statements

                             December 31, 1998 and 1997

                       (In thousands, except share information)

       Consummation of the Company's initial public offering created an
       ownership change that has resulted in approximately $12,600 of the pre -
       1994 net operating loss carryforwards being limited to approximately
       $1,750 per year. In addition, approximately $7,108 are further limited to
       approximately $967 per year due to changes in the Company's ownership
       structure during 1991.

(8)    CONTINGENCIES

       EMPLOYMENT AGREEMENTS

       The Company has employment contracts with two key officers that in the
       event of their termination provide for total payments up to approximately
       $365.

(9)    BENEFIT PLANS

       The Company sponsors a voluntary contribution profit sharing and savings
       plan under Section 401(k) of the Internal Revenue Code which is available
       to substantially all employees. Employees can make voluntary
       contributions up to limitations prescribed by the Internal Revenue Code.
       Company matching contributions are discretionary. For the years ended
       December 31, 1998, 1997 and 1996 the Company made no discretionary
       matching contributions.

(10)   CONCENTRATION OF RISK

       (a)    SUPPLIERS

              The Company currently procures certain components and services for
              its products from single sources. The Company purchases these
              components and services on a purchase order basis, does not carry
              significant inventories of these components and does not have any
              long-term supply contracts with its sole source vendors. If the
              Company were to change any of its sole source vendors, the Company
              would be required to requalify the components with each new
              vendor. Requalification could prevent or delay product shipments
              which could materially adversely affect the Company's results of
              operations. In addition, the Company's reliance on sole source
              vendors involves several risks, including reduced control over the
              price, timely delivery, reliability and quality of the components.
              Any inability of the Company to obtain timely deliveries of
              components of acceptable quality in required quantities or any
              increases in the prices of components for which the Company does
              not have alternative sources could materially adversely affect the
              Company's business, financial condition and results of operations.

       (b)    CREDIT RISK

              The Company generally sells its products to customers engaged in
              the design and/or manufacture of high technology products either
              recently introduced or not yet introduced to the marketplace.
              Substantially all the Company's trade accounts receivable are due
              from such sources.

                                       21                            (Continued)

                           TRIQUINT SEMICONDUCTOR, INC.

                    Notes to Consolidated Financial Statements

                             December 31, 1998 and 1997

                       (In thousands, except share information)

              The Company performs continuing credit evaluations of its
              customers and generally does not require collateral; however, in
              certain circumstances, the Company may require letters of credit
              from its customers.


(11)   SEGMENT INFORMATION

       The Company has adopted SFAS No. 131, DISCLOSURES ABOUT SEGMENTS OF AN
       ENTERPRISE AND RELATED Information. SFAS No. 131 establishes standards
       for the reporting by public business enterprises of information about
       operating segments, products and services, geographic areas and major
       customers. The method for determining what information to report is based
       on the way that management organizes the segments within the Company for
       making operating decisions and assessing financial performance.

       The Company's chief operating decision maker is considered to be the
       President and Chief Executive Officer (CEO). The Company's CEO evaluates
       both consolidated and disaggregated financial information in deciding how
       to allocate resources and assess performance. The CEO uses certain
       disaggregated financial information for the Company's three product
       lines: Wireless Communications; Telecommunications and Data
       Communications; and Millimeter Wave Communications.

       The Company has aggregated its three product lines into a single
       reportable segment as allowed under SFAS No. 131 because these product
       lines have similar long-term economic characteristics, such as average
       gross margin, and product lines are similar in regards to (a) nature of
       products and production processes, (b) type of customers, and (c) method
       used to distribute products.

       Accordingly, the Company describes its reportable segment as gallium
       arsenide integrated circuits for the communications market. All of the
       Company's revenues result from sales in its product lines. The Company's
       operating expenses are allocated to its three product lines, with the
       exception of certain manufacturing variances (cost of goods sold) and, to
       a lesser extent, certain general and administrative expenses for all
       years presented and, for 1998, the Company's legal settlement discussed
       in note 12. Unallocated Corporate operating expenses totaled $12,103,
       $8,538 and $4,651 for the years ended December 31, 1998, 1997 and 1996,
       respectively. In addition, all non-operating income and expenses are
       recorded in Corporate. The Company does not allocate assets to its
       product lines.

       Revenues by product line (as defined by the Company) as a 
       percentage of total revenues for years ended December 31, 1998, 
       1997 and 1996 were as follows: Wireless Communications, 45%, 47% 
       and 49%, respectively; Telecommunications and Data Communications, 
       18%, 53% and 51%, respectively; Millimeter Wave Communications, 
       37%, -0-% and -0-%, respectively.

       Revenues outside of the United States were approximately $26,800,
       $24,300 and $18,100 in 1998, 1997 and 1996, respectively, of which 
       sales to Canada comprised $10,524, $ 8,527 and $6,100, respectively. 
       There were no other foreign countries to which sales represented 5% or 
       more of total revenues.

       or more of total revenues for each period, are summarized as follows:

       Related receivables from such customers were 26% and 31% of trade

(12)   LITIGATION


              SETTLEMENT OF LAWSUIT

              On July 12, 1994, a stockholder class action lawsuit was filed
              against the Company, its underwriters, and certain of its
              officers, directors and investors in the United States District
              Court for the Northern District of California. The suit alleged
              that the Company, its underwriters, and certain of its officers,
              directors and investors intentionally misled the investing public
              regarding the financial prospects of the Company. Following the
              filing of the complaint, the plaintiffs dismissed without
              prejudice a director defendant, the principal stockholder
              defendant, the underwriter defendants and certain analyst
              defendants. During 1998, the Company settled the action and
              recorded a special charge of $1,400 associated with the settlement
              of the lawsuit and the related legal expenses, net of accruals.

              From time to time the Company is involved in various claims and
              legal actions arising in the ordinary course of business. In the
              opinion of management, the ultimate disposition of these matters
              will not have a material effect on the Company's consolidated
              financial position, results of operations or cash flows.

(13)   SUBSEQUENT EVENT

              On February 26, 1999, a lawsuit was filed against 88 firms, 
              including the Company, in the United States District Court for 
              the District of Arizona. The suit alleges that the defendants 
              infringe upon certain patents held by The Lemelson Medical, 
              Education and Research Foundation, Limited Partnership. The 
              Company believes the suit is without merit and intends to 
              vigorously defend itself against the charges.

EQUITY AND RELATED
STOCKHOLDER MATTERS

     The Company made its initial public offering on December 13, 1993 at
a price of $11.00 per share.  The Company's Common Stock is quoted on
the Nasdaq Stock Market's National Market under the symbol "TQNT".

Common Stock.

     The Company has never declared or paid cash dividends on its Common Stock

Company's line of credit with a financial institution contains a restrictive
covenant which could limit the Company's ability to pay cash dividends or make
stock repurchases. Any future determination to pay cash dividends will also be
at the discretion of the Board of Directors and will be dependent upon the
Company's financial condition, results of operations, capital requirements,
general business conditions and such other factors as the Board of Directors
deems relevant.
