PART I

We design, develop and market high-performance interface integrated circuits, or ICs, used in many of today’s advanced electronic systems. Interface ICs, such as interface logic, switches and timing management products, transfer, route and time electrical signals among a system’s microprocessor, memory and various peripherals and between interconnected systems. Our interface products increase system bandwidth in applications such as notebook computers, servers, network switches and routers, storage area networks and wireless base stations. We offer products that increase bandwidth by widening the data path, or bus (enlarging the pipe), increasing the data rate (increasing the flow rate through the pipe), or allowing multiple, simultaneous transactions on the bus.

We have combined our extensive design technology and applications knowledge with our responsiveness to the specific needs of electronic systems developers to become a leading supplier of high-performance interface ICs. We have evolved from one product line in fiscal 1992 to four developed and growing product lines—SiliconSwitch^™, SiliconInterface^™ Logic, SiliconClock^™ and SiliconConnect^™—aimed at providing an increasing breadth of interface IC solutions to our current and target customers. We have a comprehensive portfolio of products including 77 new products that were introduced during fiscal year 2003. Our worldwide customers include leading OEMs, contract manufacturers and distributors.

Our website address is http://www.pericom.com. Our annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and all amendments to those reports, and the proxy statement for our annual meeting of shareholders are all available, free of charge, on our website as soon as practicable after we file the reports with the Securities and Exchange Commission.

INDUSTRY BACKGROUND

OVERVIEW

The presence of electronic systems and subsystems permeates our everyday life, as evidenced by the growth of the personal computer, mobile communications, networking and consumer electronics markets. The growth of these markets has been driven by systems characterized by ever-improving performance, flexibility, reliability and multi-functionality, as well as decreasing size, weight and power consumption. Advances in ICs through improvements in semiconductor technology have contributed significantly to the increased performance of, and demand for, electronic systems and to the increasing representation of ICs as a proportion of overall system cost. This technological progress has occurred at an accelerating pace, while the cost of electronic systems has remained steady or declined.

The development of high-performance personal computers, the requirement for higher network performance and the increased level of connectivity among different types of electronic devices have driven the demand for high-speed, high-performance interface circuits to handle the transfer, routing and timing of digital and analog signals at high speeds with minimal loss of signal quality. High-speed signal transfer is essential to fully utilize the speed and bandwidth of the microprocessor, the memory and the LAN or WAN. High signal quality is equally essential to achieve optimal balance between high data transmission rates and reliable system operation. Without high signal quality, transmission errors occur as bandwidth increases. Market requirements for interface circuits are driven by the same market pressures as those imposed on microprocessors, including higher speed, reduced power consumption, lower-voltage operation, smaller size and higher levels of integration.

Our interface products serve to increase system bandwidth in applications such as servers, network switches and routers, storage area networks, wireless basestations, and notebook computers. Bandwidth can be increased by widening the datapath (widening the pipe), increasing the clock rate (increase the flowrate through the pipe) or allowing multiple, simultaneous transactions on the bus using a crossbar switch. We are pioneering technology in each of these areas.

The problems associated with signal quality that must be addressed by the interface ICs are magnified by increases in the speeds at which interface ICs must transfer, route and time electrical signals, the number of interconnected devices that send or receive signals and the variety of types of signals processed by the interface ICs. The most significant performance challenges faced by designers of interface ICs are the requirements to transfer signals at high speed with low propagation delay, minimize signal degradation such as “noise,” “jitter,” and “skew” and reduce electromagnetic interference (“EMI”). Minimizing propagation delay, sources of signal degradation and interference is needed to enable today’s state-of-the-art electronic systems to function reliably.

We believe that several major market trends make reliable operations of systems at high frequency and high data transfer rates critical. Internet and high-performance network applications continue to push for more data bandwidth on system buses and across system boundaries. Computer and networking system clock frequencies continue to increase at a very rapid rate, shortening the time available to perform data transfers. While the data transfer rate has typically increased every few years, the continuing desire for higher system reliability with minimal system downtime creates increasing pressure to achieve lower data error rates. Increasing system-wide EMI emissions resulting from higher-frequency ICs compels system designers to develop and implement new ways to further reduce these emissions. These factors all increase the need for very high-speed interface circuits with outstanding performance specifications.

With processing power continuing to double every 18 months (Moore’s law) the speed at which microprocessors can access memory becomes the system bandwidth constraint in high-speed computing. We have developed solutions with market leaders to support higher speed processor-memory interfacing to support the Double Data Rate (“DDR” and “DDR II”) SDRAM, both on the system motherboard and memory modules.

In server applications, we support higher system bandwidth through the use of bus switches to isolate the system’s memory modules from the bus when they are not being addressed. Our interface products are also used to enable live insertion of PCI boards (“hot swapping”). This prevents system downtime when boards need to be replaced. We have similar products for hot-docking notebook computers and our products are used in the majority of the notebook computers on the market today.

In high-bandwidth systems data transfer needs to be synchronized, creating a high demand for timing products. Our timing products provide the precise timing signals needed to ensure reliable data transfer at high speeds in applications ranging from notebook computers to network switches. As systems continue to grow in processing power and complexity the demand for these products will accelerate. The demand for higher precision will also continue to increase as timing margins shrink in higher bandwidth systems.

Electronic systems designers and OEMs have increasingly required solutions to the technical challenges described above in order to take advantage of continuing speed and performance enhancements in microprocessor and memory ICs. These customers have also continued to migrate from single-part vendors to suppliers who can provide multiple parts for their systems, both to reduce the number of vendors they must deal with and to address interoperability requirements among the interface ICs within the system. Due to the short design times and product life cycles these customers face for their own products, they are requiring rapid response time and part availability from interface IC vendors. Interface IC vendors are further required to accomplish these tasks in a cost-effective manner that flexibly responds to specific customer needs.

THE PERICOM STRATEGY

We are a leading supplier of high-performance interface ICs. While our products address a wide spectrum of applications, we have focused our resources on solving bandwidth and interoperability bottlenecks in customers’ systems using our high performance interface technology. With processing power doubling every 18 months historically, the speed at which microprocessors can access memory becomes the bandwidth constraint in high speed computing. We have developed solutions with Intel, IBM and other market leaders to support higher-speed processor-memory interfacing, which support the latest memory standards, on both the system motherboard and the memory modules. In server applications, we support higher system bandwidth through the use of high frequency clock products, which provide timing signals to synchronize data transfer, and bus switches that isolate a system’s memory modules from the bus when they are not being addressed.

Products are defined in collaboration with the industry-leading OEMs and industry enablers such as Intel and IBM, and our modular design methodology shortens our time to market and time to volume relative to our competitors. The key elements of our strategy are:

Market Focus. Our market strategy is to focus on the high-growth, high-performance segments of the computing, networking and telecommunications markets. Currently, we design and sell products for specific high-volume applications within these target markets, including notebook computers, computer servers, local area network (LAN), and wide area network (WAN), switches, routers and hubs and multi-function office peripherals such as printers and copiers. Our customers and end-users of our products include a number of leading OEMs in each market:

We intend to pursue new opportunities in markets where our rapid-cycle IC design and development expertise and understanding of the product evolution of our customers gives us the opportunity to become a leading solution supplier.

Customer Focus. Our customer strategy is to use a superior level of responsiveness to customer needs to continually expand our customer base as well as sell a wider range of products to our existing and targeted new customers. Key elements of our customer strategy are:

Table of Contents

we have also initiated electronic data interchange, or EDI, and remote warehousing programs, annual purchase and supply programs, joint development projects and other services intended to enhance our position as a key vendor.

Technology Focus. Our technology strategy is to maintain a leading position in the development of new, higher-performance interface ICs by continuing to design additional core cells that address the more challenging problems of signal interface as electronic systems become faster and require lower power and voltages. Our primary efforts are in the creation of additional proprietary digital, analog and mixed-signal functionality. We are working closely with our wafer suppliers to incorporate their advanced CMOS process technologies to improve our ability to introduce next generation products expeditiously. We are continuing to expand our patent portfolio with the goal of providing increasingly proprietary product lines.

Manufacturing Focus. Our manufacturing strategy is closely integrated with our focus on customer needs. Central to this strategy is our intent to support high-volume shipment requirements on short notice from customers. We design products so that we may manufacture many different ICs from a single partially-processed wafer. Accordingly, we keep inventory in the form of wafer banks, from which wafers can be completed to produce a variety of specific ICs in as little as two to four weeks. This approach has enabled us to reduce our overall work-in-process inventory while providing increased availability to produce a variety of finished products. In addition, we keep some inventory in the form of die banks, which can become finished product in two weeks or less. We have established relationships with three leading foundries, Chartered Semiconductor Manufacturing Pte, Ltd. (“Chartered”), Taiwan Semiconductor Manufacturing Corporation (“TSMC”), and Hynix Semiconductor America, Inc (“Hynix”). We are maintaining our relationship with New Japan Radio Corporation (“NJRC”) for some of our products that are manufactured in high-voltage CMOS processes.

Strategic and Collaborative Relationships Focus. We pursue a strategy of entering into new relationships and expanding existing relationships with companies that engage in the product design, manufacturing and marketing of ICs. We believe that these relationships have enabled us to access additional design and application expertise, accelerate product introductions, reduce costs and obtain additional needed capacity. In product design, we have engaged Pericom Technology, Inc., an affiliated company, and other design houses to develop interface ICs as a means of rapidly expanding our product portfolio. We have established collaborative relationships with leading wafer manufacturers that have high performance digital core libraries that we can use in our future products. We have also made strategic investments in several companies with whom we have obtained rights to certain technologies and are engaged in collaborative research and development.

PRODUCTS

We have used our expertise in high-performance digital, analog and mixed-signal IC design, our reusable core cell library and our modular design methodology to achieve a rapid rate of new product introductions. Within each of our four product lines, the product portfolio has evolved from a standard building block into both standard products of increasing performance and application-specific standard products, or ASSPs, which are tailored to meet a specific high volume application. Within each product family we continue to address the common trends of decreasing supply voltage, higher integration and faster speeds.

SiliconSwitch^™

Through our SiliconSwitch^™ product line, we offer a broad range of high-performance ICs for switching digital and analog signals. The ability to switch or route high-speed digital or analog signals with minimal delay and signal distortion is a critical requirement in many high-speed computers, networking and

multimedia applications. Historically, systems designers have used mechanical relays and solid-state relays which have significant disadvantages as compared to IC switches: mechanical relays are bulky, dissipate significant power and have very low response times; solid-state relays are expensive.

Digital Switches. We offer a family of digital switches in 8-, 16- and 32-bit densities that address the switching needs of high-performance systems. These digital switches offer performance and cost advantages over traditional switch functions, offering both low on-resistance and capacitance, low propagation delay (less than 250 picoseconds), low standby current (less than 1 microamp) and series resistor options that support low electromagnetic interference, or EMI, emission requirements. Applications for our digital switches include 5-volt to 3.3-volt signal translation, high-speed data transfer and switching between microprocessors, PCI slots, and multiple memories, and hot plug interfaces in notebook and desktop computers, servers and switching hubs and routers. We also have two families of 3.3-volt switches offering industry-leading performance in switching times, and low capacitance for bus isolation applications. We continued to expand the number of devices and the performance of these families during fiscal 2003.

Analog Switches. We offer a family of analog switches for low-voltage (2- to 7-volt) applications such as multimedia audio and video signal switching with enhanced characteristics such as low power, high bandwidth, low crosstalk and low distortion to maintain analog signal integrity. Our analog switches have significantly lower distortion than traditional analog switches due to our advanced CMOS switch design. To support space-constrained applications, such as wireless handsets and global positioning system receivers, we introduced a new set of 5-vold Low R-on 1 Ohm switches in tiny SOT-23, So-7 and new 6-pin and 12-pin ultra small TDFN packages. To complement this low-voltage family we also offer a higher voltage (17-volt) analog switch family for applications requiring higher signal range, such as instrumentation, telecommunications and industrial control.

LAN Switches and Video Switches. We offer a line of application specific standard products (“ASSP”) switches that address the high performance demands of 10/100/1000 Ethernet LANs and high bandwidth video switches that enable the switching between different video sources associated with video graphic cards and flat panel displays. We continue to expand our innovations in this area to address next generation Networking and Media platform.

SiliconInterface^™

Through our SiliconInterface^™ product line, we offer a broad range of high- performance 5-volt, 3.3-volt, 2.5-volt, and 1.8-volt CMOS logic interface circuits. These products provide logic functions to handle data transfer between microprocessors and memory, bus exchange, backplane interface and other logic interface functions where high-speed, low-power, low-noise and high-output drive characteristics are essential.

5-Volt Interface Logic. Our high-speed 5-volt interface logic products in 8- and 16-bit configurations address specific system applications, including a “Quiet Series” family for high-speed, low-noise, point-to-point data transfer in computing and networking systems and a “Balanced Drive” family with series resistors at output drivers to reduce switching noise in high-performance computers. We continue to provide a complete portfolio of 5-volt FCT logic products that supports many legacy data communications and telecommunications switch platforms.

3.3-Volt Interface Logic. To support the trend toward lower system voltages for higher silicon integration, from 8-Bit to 32-Bits, system performance and power savings we offer five families of 3.3-volt interface logic to address a range of performance and cost requirements with very low power consumption. As the industry continues to migrate to 3.3-volt interface, we continued to enhance and expand our 3.3-volt logic product portfolio with the introduction of a new 16-bit logic family called LVTC targeted to replace power hungry LVT BiCMOS logic in the Telecom market place. Our ASIC design methodology and existing cell based designs contribute to our rapid product development in this area.

2.5-Volt Interface Logic. Our 2.5-volt product families include three new logic families to address 2.5- and 1.8-volt operation. We have a family of products with high output current offering sub-2.5 nanosecond propagation delays and the lowest power consumption in its class. We also have a lower balanced drive family with a propagation delay of less than 2 nanoseconds to support high-speed processor-memory interfacing and a balanced drive family optimized for low-noise operation at very low voltages. Increasingly, networking, PC and memory module manufacturers are demanding application specific logic products. We have met this challenge in 2003 by introducing new logic functions that support next generation DDR I-333 and DDR I-400 register products that meet the demands of current and next generation DDR I memory module applications associated with the PC & Server markets.

SOTiny Gates. To address the growing needs of the marketplace requirements of sourcing single and dual gate logic solutions, we expanded our SOTiny gate families to include 5V TTL translators. These products operate from 1.65v to 5v to address the interface needs associated in many applications. We continue to tap into new product markets in the areas of communication, PC peripherals, and consumer digital systems.

SiliconClock^™

In high bandwidth systems data transfer needs to be synchronized, creating a demand for timing products. Our timing products provide the precise timing signals needed to ensure reliable data transfer at high speeds in applications ranging from notebook computers to network switches. As systems continue to grow in processing power and complexity, the demand for these products is expected to accelerate. The demand for precision will also increase as timing margins shrink in higher bandwidth systems.

Through our SiliconClock^™ product line, we offer a broad range of general-purpose solutions including voltage control crystal oscillators (VCXO), clock buffers, zero-delay clock drivers and frequency synthesizer products for a wide range of microprocessor systems, as well as a number of ASSP timing products for laser printers, registered memory modules, storage area networks, servers, networking, and set-top box applications.

Clock Buffers and Zero-Delay Clock Drivers. Clock buffers receive a clock signal from a frequency source and create multiple copies of the same frequency for distribution across system boards. We offer 2.5-volt, 3.3-volt and 5-volt clock buffers for high-speed, low-skew applications in computers and networking equipment. For systems that require higher performance, we are developing differential clock buffers with frequencies up to 800MHz. Zero-delay clocks virtually eliminate propagation delays by synchronizing the clock outputs with the incoming frequency source. Our 5-volt, 3.3-volt, 2.5-volt and 1.8-volt zero-delay clock drivers offer frequencies of up to 270 MHz for applications in networking switches, routers and hubs, computer servers, and memory modules. Timing products to support the emerging double date rate (DDR) and DDR II memory technologies are available today.

Clock Frequency Synthesizers. Clock frequency synthesizers generate various output frequencies using a single input frequency source. Clock frequency synthesizers are used to provide critical timing signals to microprocessors, memory and peripheral functions. Our clock synthesizers support a wide range of microprocessor systems and their associated integrated chipsets for server, notebook and desktop PC products. We also offer a clock synthesizer developed specifically for laser printer products.

Programmable Clocks. In large computing and communications systems customers need to provide precise timing across large printed circuit boards, or PCBs. At the very high frequencies used today these large PCB traces can result in significant timing delays and matching these delays (or timing skew) can be a significant challenge for the system designer. We have responded to this challenge with a family of programmable skew clock products.

SiliconConnect^™

SiliconConnect^™ is our newest product line and offers the highest level of complexity and integration among our products. It consists of our LVDS family of high-speed differential drivers, receivers, and transceivers, PCI Bridges, and our first SERDES product.

To support higher system bandwidth at acceptable noise and power levels customers are increasingly moving to serial rather than parallel architectures and using differential signaling to reduce noise and EMI. We continue to refine our LVDS product families by offering a comprehensive portfolio of drivers, receivers and transceivers with data rates of 660 megabits per second, or Mbps, and allowing point-to-point connections over distances up to 10 meters. This new low-voltage differential signaling, or LVDS, standard offers a number of improvements over the older emitter-coupled logic, or ECL, and pseudo emitter-coupled logic, or PECL, in applications requiring lower power consumption and noise. Pericom’s LVDS family is approximately 50 products today.

In 2003 we expanded our PCI Bridge product portfolio by introducing 3 Intel compatible devices to the market. These devices complement our current proprietary enhanced 3-port bridge device. Design activity and initial revenues have been promising for these high margin products. We also continued to invest in developing advanced devices including our PCI-X Bridge device, which is in development and, along with customer specific and performance enhanced versions. Bridge devices are used in industrial PCs and certain other computers; on RAID and Fibre Channel cards in the Storage Area Network space; Multi-channel Ethernet NICs; and routers and switches.

We are continuing to enhance and refine our existing product lines, while working to add next-generation products that address new market opportunities on a timely basis. See “Risk Factors; Factors That May Affect Operating Results—If we do not develop products that our customers and end-users design into their products, or if their products do not sell successfully, our business and operating results could be harmed.”

CUSTOMERS

The following is a list of some of our customers and end-users:

Our customers include a broad range of end-user customers and OEMs in the computer, peripherals, networking and telecommunications markets as well as the contract manufacturers that service these markets. Our direct sales are billings directly to a customer who may in turn sell through to an end-user customer. Our end-user customers may buy directly or through our distribution or contract manufacturing channels. In fiscal 2003, our direct sales to Solectron, a global contract manufacturer, and Techmosa, an

10

Table of Contents

international distributor, each accounted for approximately 12% of net revenues and direct sales to our top five customers accounted for approximately 45% of net revenues. In fiscal 2003, one end user customer, Compaq Computer, accounted for 11% of gross revenues less returns and sales to our top five end user customers accounted for 39% of gross revenues less returns. In fiscal 2002, our direct sales to Techmosa accounted for approximately 14% of net revenues and direct sales to our top five customers accounted for approximately 44% of net revenues. In fiscal 2002, three end-user customers each accounted for more than 10% of gross revenues less returns. Dell Computer, Compaq Computer, and Cisco Systems accounted for 15%, 12% and 11% of gross revenues less returns, respectively, and sales to our top five end-user customers were approximately 50% of gross revenues less returns. In fiscal 2001, our direct sales to Techmosa accounted for approximately 10% of net revenues, and direct sales to our top five customers accounted for approximately 36% of net revenues. In fiscal 2001 one end-user customer, Cisco Systems, accounted for approximately 12% of gross revenues less returns and sales to our top five end-user customers were approximately 39% of gross revenues less returns. See “ Risk Factors; Factors That May Affect Operating Results – The demand for our products depends on the growth of our end-user customer markets” and “Risk Factors; Factors That May Affect Operating Results – A large portion of our revenues is derived from sales to a few customers, who may cease purchasing from us at any time.”

Contract manufacturers have become important customers for us as systems designers in our target markets are increasingly outsourcing portions of their manufacturing. In addition, these contract manufacturers are playing an increasingly vital role in determining which vendors’ ICs are incorporated into new designs.

DESIGN AND PROCESS TECHNOLOGY

Our design efforts focus on the development of high-performance digital, analog and mixed-signal ICs. To minimize design cycle times of high-performance products, we use a modular design methodology that has enabled us to produce many new products each year and to meet our customers’ need for fast time-to-market response. This methodology uses state-of-the-art computer-aided design software tools such as high-level description language, or HDL, logic synthesis, full-chip mixed-signal simulation, and automated design layout and verification and uses our library of high-performance digital and analog core cells. This family of core cells has been developed over several years and contains high-performance, specialized digital and analog functions not available in commercial ASIC libraries. Among these cells are our proprietary mixed-voltage input/output, or I/O, cells, high-speed, low-noise I/O cells, analog and digital phase-locked loops, or PLLs, charge pumps and data communication transceiver circuits using low voltage differential signaling. We have been granted 61 U.S. patents and have at least 26 U.S. patent applications pending. Another advantage of this modular design methodology is that it allows the application of final design options late in the wafer manufacturing process to determine a product’s specific function. This option gives us the ability to use pre-staged wafers, which significantly reduces the design and manufacturing cycle time and enables us to respond rapidly to a customer’s prototype needs and volume requirements.

We use advanced CMOS processes to achieve higher performance and lower die cost. Our process and device engineers work closely with our independent wafer foundry partners to develop and evaluate new process technologies. Our process engineers also work closely with circuit design engineers to improve the performance and reliability of our cell library. We currently manufacture a majority of our products using 0.8-, 0.6-, 0.5-, 0.35- and 0.25-micron CMOS process technologies and are currently developing new products using 0.18-micron technology. We are also using a high-voltage CMOS process developed by one of our wafer suppliers in the design of higher voltage switch products.

SALES AND MARKETING

We market and distribute our products through a worldwide network of independent sales representatives and distributors supported by our internal and field sales organization. Sales to domestic and international distributors represented 59% of our net revenues in fiscal 2003, 54% of our net revenues in fiscal 2002 and 54% of our net revenues in fiscal 2001. The percentage increase from fiscal 2002 to fiscal 2003 was largely due to the transition of business to the international distribution channel. Our major distributors in the United States include All American Semiconductor, Arrow Electronics, Inc. Bell Microproducts, Future

Table of Contents

Electronics and Nu Horizons Electronics. Our major international distributors include Chinatronics (Hong Kong), Desner Electronics (Singapore), EPCO Technology Co., Ltd. (Taiwan), Internix (Japan), MCM (Japan) and Techmosa (Taiwan).

We have five regional sales offices in the United States and international sales offices in Taiwan, Korea, Singapore, Japan and the United Kingdom. International sales comprised approximately 68% of our net revenues in fiscal 2003, approximately 67% of our net revenues in fiscal 2002, and approximately 49% of our net revenues in fiscal 2001. We also support field sales design-in and training activities with application engineers. Most marketing and all product management personnel are located at our corporate headquarters in San Jose, California. We also have marketing personnel located in Taiwan.

We focus our marketing efforts on market knowledge, product definition, new product introduction, product marketing and advertising. We use advertising both domestically and internationally to market our products independently and in cooperation with our distributors. Pericom product information is available on our web site, which contains overview presentations, technical information on our products, and offers design modeling/applications support plus sample-request capabilities online. We also publish and circulate technical briefs relating to our products and their applications.

We believe that contract manufacturing customers are strategically important and we employ sales and marketing personnel who focus on servicing these customers and on expanding our product sales via these customers to OEMs. In addition, we use programs such as EDI, bonded inventories and remote warehousing to enhance our service and attractiveness to contract manufacturers.

MANUFACTURING

We have adopted a fabless manufacturing strategy by subcontracting our wafer production to independent wafer foundries. We have established collaborative relationships with selected independent foundries with whom we can develop a strategic relationship to the benefit of both parties. We believe that our fabless strategy enables us to introduce high performance products quickly at competitive cost. To date, our principal manufacturing relationships have been with Chartered Semiconductor Manufacturing Pte, Ltd., Taiwan Semiconductor Manufacturing Corporation and Hynix Semiconductor America, Inc. We have also used New Japan Radio Corporation and Austria Mikro Systeme GmbH as foundries. We have an ongoing effort to qualify new foundry vendors that offer cost or other advantages.

We primarily rely on foreign subcontractors for the assembly of our products and, to a lesser extent, for the testing and packaging of our finished products. Some of these subcontractors are our single source supplier for certain new packages. We perform some testing and packaging of our finished products in our in-house manufacturing facility.

COMPETITION

The semiconductor industry is intensely competitive. Significant competitive factors in the market for high-performance ICs include the following:

12

Table of Contents

Our competitors include Cypress Semiconductor Corporation, Fairchild Semiconductor Corporation, Integrated Circuit Systems, Inc., Integrated Device Technology, Inc., Intel Corp. Maxim Integrated Products, Inc., Philips and Texas Instruments, Inc. Most of those competitors have substantially greater financial, technical, marketing, distribution and other resources, broader product lines and longer-standing customer relationships than we do. We also compete with other major or emerging companies that sell products to certain segments of our markets. Competitors with greater financial resources or broader product lines may have a greater ability to sustain price reductions in our primary markets in order to gain or maintain market share. We also face competition from the makers of ASICs and other system devices. These devices may include interface logic functions, which may eliminate the need or sharply reduce the demand for our products in particular applications.

RESEARCH AND DEVELOPMENT

We believe that the continued timely development of new interface ICs is essential to maintaining our competitive position. Accordingly, we have assembled a team of highly skilled engineers whose activities are focused on the development of signal transfer, routing and timing technologies and products. We have design centers located in San Jose, California, Hong Kong, and Taiwan. Research and development expenses were $11.3 million in fiscal 2003, $11.7 million in fiscal 2002 and $11.0 million in fiscal 2001. Additionally, we actively seek cooperative product development relationships.

INTELLECTUAL PROPERTY

In the United States, we hold 61 patents covering certain aspects of our product designs and have at least 26 additional patent applications pending. We expect to continue to file patent applications where appropriate to protect our proprietary technologies; however, we believe that our continued success depends primarily on factors such as the technological skills and innovation of our personnel, rather than on our patents.

EMPLOYEES

As of June 30, 2003, we had 215 full-time employees (4 are temporary employees) and 1 part-time employee, including 39 in sales, marketing and customer support, 71 in manufacturing, assembly and testing, 81 in engineering and quality assurance and 25 in finance and administration, including information systems. We have never had a work stoppage and no employee is represented by a labor organization. We consider our employee relations to be good.

products; our ability to respond rapidly to customer needs; expanding product sales; future economic conditions or performance, and any statement of assumptions underlying any of the foregoing. In some cases, forward-looking statements can be identified by the use of terminology such as “may,” “will,” “expects,” “plans,” “anticipates,” “estimates,” “potential,” or “continue,” or the negative thereof or other comparable terminology. Although we believe that the expectations reflected in the forward-looking statements contained herein are reasonable, there can be no assurance that such expectations or any of the forward-looking statements will prove to be correct, and actual results could differ materially from those projected or assumed in the forward-looking statements. Some of the factors that could cause our actual results to differ materially are set forth below and elsewhere in this report. All forward-looking statements and reasons why results may differ included in this Form 10-K are made as of the date hereof, and we assume no obligation to update any such forward-looking statement or reason why actual results may differ.

Our results of operations have been adversely affected by the ongoing slowdown in the global economy.

Over the past several years, the global economy has been experiencing a slowdown due to many factors, including decreased consumer confidence, unemployment, the ongoing threat and cost of terrorism and reduced corporate profits and capital spending. As a result of these unfavorable economic conditions, we continue to experience reduced new customer order rates. If these economic conditions in the United States continue or worsen or if a wider or global economic slowdown occurs, our business, financial condition and results of operations may be materially and adversely affected.

Downturns in the semiconductor industry, rapidly changing technology and evolving industry standards can harm our operating results.

The semiconductor industry has historically been cyclical and periodically subject to significant economic downturns—characterized by diminished product demand, accelerated erosion of selling prices and overcapacity—as well as rapidly changing technology and evolving industry standards. The semiconductor industry continued to be in such a downturn period throughout 2003. Our operating results have been harmed by excess supply in the semiconductor industry. Accordingly, we may in the future experience substantial period-to-period fluctuations in our business and operating results due to general semiconductor industry conditions, overall economic conditions or other factors. Our business is also subject to the risks associated with the effects of legislation and regulations relating to the import or export of semiconductor products.

Intense competition in the semiconductor industry may reduce the demand for our products or the prices of our products, which could reduce our revenues.

The semiconductor industry is intensely competitive. Our competitors include Cypress Semiconductor Corporation, Fairchild Semiconductor Corporation, Integrated Circuit Systems, Inc., Integrated Device Technology, Inc., Intel Corp., Maxim Integrated Products, Inc., Philips and Texas Instruments, Inc. Most of those competitors have substantially greater financial, technical, marketing, distribution and other resources, broader product lines and longer-standing customer relationships than we do. We also compete with other major or emerging companies that sell products to certain segments of our markets. Competitors with greater financial resources or broader product lines may have a greater ability to sustain price reductions in our primary markets in order to gain or maintain market share.

We believe that our future success will depend on our ability to continue to improve and develop our products and processes. Unlike us, many of our competitors maintain internal manufacturing capacity for the fabrication and assembly of semiconductor products. This ability may provide them with more reliable manufacturing capability, shorter development and manufacturing cycles and time-to-market advantages. In addition, competitors with their own wafer fabrication facilities that are capable of producing products with the same design geometries as ours may be able to manufacture and sell competitive products at lower prices. Any introduction of products by our competitors that are manufactured with improved process technology could seriously harm our business. As is typical in the semiconductor industry, our competitors

14

Table of Contents

have developed and marketed products that function similarly or identically to ours. If our products do not achieve performance, price, size or other advantages over products offered by our competitors, our products may lose market share. Competitive pressures could also reduce market acceptance of our products, reduce our prices and increase our expenses.

We also face competition from the makers of ASICs and other system devices. These devices may include interface logic functions, which may eliminate the need or sharply reduce the demand for our products in particular applications.

Product price declines and fluctuations may cause our future financial results to vary.

Historically, selling prices in the semiconductor industry generally, as well as for our products, have decreased significantly over the life of each product. We expect that selling prices for our existing products will continue to decline over time and that average selling prices for our new products will decline significantly over the lives of these products. Declines in selling prices for our products, if not offset by reductions in the costs of producing these products or by sales of new products with higher gross margins, would reduce our overall gross margins and could seriously harm our business.

If we do not develop products that our customers and end-users design into their products, or if their products do not sell successfully, our business and operating results would be harmed.

We have relied in the past and continue to rely upon our relationships with our customers and end-users for insights into product development strategies for emerging system requirements. We generally incorporate new products into a customer’s or end-user’s product or system at the design stage. However, these design efforts, which can often require significant expenditures by us, may precede product sales, if any, by a year or more. Moreover, the value to us of any design win will depend in large part on the ultimate success of the customer’s or end-user’s product and on the extent to which the system’s design accommodates components manufactured by our competitors. If we fail to achieve design wins or if the design wins fail to result in significant future revenues, our operating results would be harmed. If we have problems developing or maintaining our relationships with our customers and end-users, our ability to develop well-accepted new products may be impaired.

The trading price of our common stock and our operating results are likely to fluctuate substantially in the future.

The trading price of our common stock has been and is likely to continue to be highly volatile. Our stock price could fluctuate widely in response to factors some of which are not within our control, including:

In the past, our quarterly operating results have varied significantly and are likely to fluctuate in the future. A wide variety of factors affect our operating results. These factors include the following:

15

Table of Contents

All of these factors are difficult to forecast and could seriously harm our operating results. Our expense levels are based in part on our expectations regarding future sales and are largely fixed in the short term. Therefore, we may be unable to reduce our expenses fast enough to compensate for any unexpected shortfall in sales. Any significant decline in demand relative to our expectations or any material delay of customer orders could harm our operating results. In addition, if our operating results in future quarters fall below public market analysts’ and investors’ expectations, the market price of our common stock would likely decrease.

The markets for our products are characterized by rapidly changing technology, and our financial results could be harmed if we do not successfully develop and implement new manufacturing technologies or develop, introduce and sell new products.

The markets for our products are characterized by rapidly changing technology, frequent new product introductions and declining selling prices over product life cycles. We currently offer over 700 products. Our future success depends upon the timely completion and introduction of new products, across all of our product lines, at competitive price and performance levels. The success of new products depends on a variety of factors, including the following:

We may also experience delays, difficulty in procuring adequate fabrication capacity for the development and manufacture of new products or other difficulties in achieving volume production of these products. Even relatively minor errors may significantly affect the development and manufacture of new products. If we fail to complete and introduce new products in a timely manner at competitive price and performance levels, our business would be significantly harmed.

The demand for our products depends on the growth of our end users’ markets.

Our continued success depends in large part on the continued growth of markets for the products into which our semiconductor products are incorporated. These markets include the following:

Any decline in the demand for products in these markets could seriously harm our business, financial condition and operating results. These markets have also historically experienced significant fluctuations in demand. We may also be seriously harmed by slower growth in the other markets in which we sell our products.

Our contracts with our wafer suppliers do not obligate them to a minimum supply or set prices. Any inability or unwillingness of our wafer suppliers generally, and Chartered Semiconductor Manufacturing Ltd. in particular, to meet our manufacturing requirements would delay our production and product shipments and harm our business.

In fiscal 2003, 2002 and 2001 we purchased approximately 72%, 68% and 59%, respectively, of our wafers from Chartered Semiconductor Manufacturing Ltd. In fiscal 2003, only three other suppliers manufactured the remainder of our wafers. In fiscal 2002 and 2001, five other suppliers manufactured the remainder of our wafers. Our reliance on independent wafer suppliers to fabricate our wafers at their production facilities subjects us to possible risks such as:

Any inability or unwillingness of our wafer suppliers generally, and Chartered in particular, to provide adequate quantities of finished wafers to meet our needs in a timely manner would delay our production and product shipments and seriously harm our business.

At present, we purchase wafers from our suppliers through the issuance of purchase orders based on our rolling six-month forecasts. The purchase orders are subject to acceptance by each wafer supplier. We do not have long-term supply contracts which obligate our suppliers to a minimum supply or set prices. We also depend upon our wafer suppliers to participate in process improvement efforts, such as the transition to finer geometries. If our suppliers are unable or unwilling to do so, our development and introduction of new products could be delayed. Furthermore, sudden shortages of raw materials or production capacity constraints can lead wafer suppliers to allocate available capacity to customers other than us or for the suppliers’ internal uses, interrupting our ability to meet our product delivery obligations. Any significant interruption in our wafer supply would seriously harm our operating results and our customer relations. Our reliance on independent wafer suppliers may also lengthen the development cycle for our products, providing time-to-market advantages to our competitors that have in-house fabrication capacity.

In the event that our suppliers are unable or unwilling to manufacture our key products in required volumes, we will have to identify and qualify additional wafer foundries. The qualification process can take up to six months or longer. Furthermore, we are unable to predict whether additional wafer foundries will become available to us or will be in a position to satisfy any of our requirements on a timely basis.

Our pending acquisition of Saronix and other potential future acquisitions may not be successful because we have not made acquisitions in the past.

We have entered into a definitive purchase option agreement to acquire certain assets and certain liabilities of Saronix LLC, a private frequency timing products company, subject to the completion of due diligence and customary closing conditions. The purchase price is expected to be under $10 million, much of which has been advanced to Saronix in the form of convertible secured loans. On September 24, 2003, we exercised this option to acquire certain assets and certain liabilities of Saronix LLC. We anticipate that this acquisition will be completed on October 1, 2003, but there can be no assurance that it will be completed on that date.

The Saronix acquisition will be our first acquisition. In the past, we have depended on internal growth and not made any acquisitions.

The Saronix acquisition and other potential future acquisitions could result in the following:

17

Table of Contents

We are not certain that we will be able to successfully integrate the Saronix business or any other businesses, products, technologies or personnel that may be acquired in the future. Our failure to do so could seriously harm our business.

As part of our business strategy, we expect to seek other acquisition prospects, in addition to Saronix, that would complement our existing product offerings, improve market coverage or enhance our technological capabilities. Although we are evaluating acquisition and strategic investment opportunities on an ongoing basis, we may not be able to locate suitable acquisition or investment opportunities. In addition, from time to time, we invest in other companies, without actually acquiring them, and such investments involve many of the same risks as are involved with acquisitions. For example, we previously made a bridge loan investment in a start up, high technology company, and we subsequently had to write off this loan in light of the financial condition of that company.

We depend on single or limited source assembly subcontractors with whom we do not have written contracts. Any inability or unwillingness of our assembly subcontractors to meet our assembly requirements would delay our product shipments and harm our business.

We primarily rely on foreign subcontractors for the assembly and packaging of our products and, to a lesser extent, for the testing of finished products. Some of these subcontractors are our single source supplier for some of our new packages. In addition, changes in our or a subcontractor’s business could cause us to become materially dependent on a single subcontractor. We have from time to time experienced difficulties in the timeliness and quality of product deliveries from our subcontractors and may experience similar or more severe difficulties in the future. We generally purchase these single or limited source components or services pursuant to purchase orders and have no guaranteed arrangements with these subcontractors. These subcontractors could cease to meet our requirements for components or services, or there could be a significant disruption in supplies from them, or degradation in the quality of components or services supplied by them. Any circumstance that would require us to qualify alternative supply sources could delay shipments, result in the loss of customers and limit or reduce our revenues.

We may have difficulty accurately predicting revenues for future periods.

Our expense levels are based in part on anticipated future revenue levels, which can be difficult to predict. Our business is characterized by short-term orders and shipment schedules. We do not have long-term purchase agreements with any of our customers, and customers can typically cancel or reschedule their orders without significant penalty. We typically plan production and inventory levels based on forecasts of customer demand generated with input from customers and sales representatives. Customer demand is highly unpredictable and can fluctuate substantially. If customer demand falls significantly below anticipated levels, our profit would be reduced.

We compete with others to attract and retain key personnel, and any loss of, or inability to attract, key personnel would harm us.

To a greater degree than non-technology companies, our future success will depend on the continued contributions of our executive officers and other key management and technical personnel. None of these

18

Table of Contents

individuals has an employment agreement with us and each one would be difficult to replace. We do not maintain any key person life insurance policies on any of these individuals. The loss of the services of one or more of our executive officers or key personnel or the inability to continue to attract qualified personnel could delay product development cycles or otherwise harm our business, financial condition and results of operations.

Our future success also will depend on our ability to attract and retain qualified technical, marketing and management personnel, particularly highly skilled design, process and test engineers, for whom competition is intense. In particular, the availability of qualified engineers is limited and competition among companies for skilled and experienced engineering personnel is very strong. During strong business cycles, we expect to experience difficulty in filling our needs for qualified engineers and other personnel.

Our limited ability to protect our intellectual property and proprietary rights could harm our competitive position.

Our success depends in part on our ability to obtain patents and licenses and preserve other intellectual property rights covering our products and development and testing tools. In the United States, we hold 61 patents covering certain aspects of our product designs and have at least 26 additional patent applications pending. Copyrights, mask work protection, trade secrets and confidential technological know-how are also key to our business. Additional patents may not be issued to us or our patents or other intellectual property may not provide meaningful protection. We may be subject to, or initiate, interference proceedings in the U.S. Patent and Trademark Office. These proceedings can consume significant financial and management resources. We may become involved in litigation relating to alleged infringement by us of others’ patents or other intellectual property rights. This type of litigation is frequently expensive to both the winning party and the losing party and takes up significant amounts of management’s time and attention. In addition, if we lose such a lawsuit, a court could require us to pay substantial damages and/or royalties or prohibit us from using essential technologies. For these and other reasons, this type of litigation could seriously harm our business. Also, although we may seek to obtain a license under a third party’s intellectual property rights in order to bring an end to certain claims or actions asserted against us, we may not be able to obtain such a license on reasonable terms or at all. See Item 3, “Legal Proceedings”.

Because it is important to our success that we are able to prevent competitors from copying our innovations, we intend to continue to seek patent, trade secret and mask work protection for our technologies. The process of seeking patent protection can be long and expensive, and we cannot be certain that any currently pending or future applications will actually result in issued patents, or that, even if patents are issued, they will be of sufficient scope or strength to provide meaningful protection or any commercial advantage to us. Furthermore, others may develop technologies that are similar or superior to our technology or design around the patents we own.

We also rely on trade secret protection for our technology, in part through confidentiality agreements with our employees, consultants and third parties. However, these parties may breach these agreements. In addition, the laws of some territories in which we develop, manufacture or sell our products may not protect our intellectual property rights to the same extent as do the laws of the United States.

The process technology used by our independent foundries, including process technology that we developed with our foundries, can generally be used by them to produce their own products or to manufacture products for other companies including our competitors. In addition, we may not have the right to implement key process technologies used to manufacture some of our products with foundries other than our present foundries.

We may not provide adequate allowances for exchanges, returns and concessions.

We recognize revenue from the sale of products when shipped, less an allowance based on future authorized and historical patterns of returns, price protection, exchanges and other concessions. We believe our

19

Table of Contents

methodology and approach are appropriate. However, if the actual amounts we incur exceed the allowances, it could decrease our revenue and corresponding gross profit.

The complexity of our products makes us highly susceptible to manufacturing problems, which could increase our costs and delay our product shipments.

The manufacture and assembly of our over 700 products are highly complex and sensitive to a wide variety of factors, including:

In a typical semiconductor manufacturing process, silicon wafers produced by a foundry are cut into individual die. These die are assembled into individual packages and tested for performance. Our wafer fabrication suppliers have from time to time experienced lower than anticipated yields of suitable die. In the event of such decreased yields, we would incur additional costs to sort wafers, an increase in average cost per usable die and an increase in the time to market for our products. These conditions could reduce our net revenues and gross margin and harm our customer relations.

We do not manufacture any of our products. Therefore, we are referred to in the semiconductor industry as a “fabless” producer. Consequently, we depend upon third party manufacturers to produce semiconductors that meet our specifications. We currently have third party manufacturers that can produce semiconductors that meet our needs. However, as the industry continues to progress to smaller manufacturing and design geometries, the complexities of producing semiconductors will increase. Decreasing geometries may introduce new problems and delays that may affect product development and deliveries. Due to the nature of the industry and our status as a “fabless” semiconductor company, we could encounter fabrication-related problems that may affect the availability of our products, delay our shipments or increase our costs.

A large portion of our revenues is derived from sales to a few customers, who may cease purchasing from us at any time.

A relatively small number of customers have accounted for a significant portion of our net revenues in each of the past several fiscal years. We expect this trend to continue for the foreseeable future. Solectron, a global contract manufacturer and Techmosa, an international distributor that in turn ships to many end users, each accounted for approximately 12% of net revenues during fiscal 2003. Sales to our top five direct customers accounted for approximately 45% of net revenues in fiscal 2003. Of our end-user customers, Compaq Computer accounted for approximately 11% of gross revenues less returns during fiscal 2003. Sales to our top five end-user customers accounted for approximately 39% of gross revenues less returns in fiscal 2003.

We do not have long-term sales agreements with any of our customers. Our customers are not subject to minimum purchase requirements, may reduce or delay orders periodically due to excess inventory and may discontinue selling our products at any time. Our distributors typically offer competing products in addition to ours. In fiscal 2003, sales to domestic and international distributors represented approximately 59% of net revenues. The loss of one or more significant customers, or the decision by a significant distributor to carry the product lines of our competitors, could decrease our revenues.

Almost all of our wafer suppliers and assembly subcontractors are located in southeast Asia, which exposes us to the problems associated with international operations.

Almost all of our wafer suppliers and assembly subcontractors are located in southeast Asia, which exposes us to risks associated with international business operations, including the following:

20

Table of Contents

In particular, there is a potential risk of conflict and further instability in the relationship between Taiwan and the People’s Republic of China. Conflict or instability could disrupt the operations of one of our principal wafer suppliers and several of our assembly subcontractors located in Taiwan.

Because we sell our products to customers outside of the United States, we face foreign business, political and economic risks that could seriously harm us.

In fiscal 2003, approximately 60% of our net revenues derived from sales in Asia and approximately 8% from sales in Europe. We expect that export sales will continue to represent a significant portion of net revenues. We intend to expand our sales efforts outside the United States. This expansion will require significant management attention and financial resources and further subject us to international operating risks. These risks include:

We are also subject to general geopolitical risks in connection with our international operations, such as political and economic instability and changes in diplomatic and trade relationships. In addition, because our international sales are denominated in U.S. dollars, increases in the value of the U.S. dollar could increase the price in local currencies of our products in foreign markets and make our products relatively more expensive than competitors’ products that are denominated in local currencies. Regulatory, geopolitical and other factors could seriously harm our business or require us to modify our current business practices.

Our shareholder rights plan may adversely affect existing shareholders.

On March 6, 2002, we adopted a shareholder rights plan that may have the effect of deterring, delaying, or preventing a change in control that otherwise might be in the best interests of our shareholders. Under the rights plan, we issued a dividend of one preferred share purchase right for each share of our common stock held by shareholders of record as of March 21, 2002. Each right entitles shareholders to purchase one one-hundredth of our newly created Series D Junior Participating Preferred Share.

In general, the share purchase rights become exercisable when a person or group acquires 15% or more of our common stock or a tender offer of 15% or more of our common stock is announced or commenced. After such event, our other stockholders may purchase additional shares of our common stock at 50% off of the then-current market price. The rights will cause substantial dilution to a person or group that attempts to acquire us on terms not approved by our Board of Directors. The rights should not interfere with any merger or other business combination approved by our Board of Directors since the rights may be redeemed by us at $0.001 per right at any time before any person or group acquire 15% or more of our outstanding common stock. These rights expire in March 2012.

Our operations and financial results could be severely harmed by natural disasters.

Our headquarters and some of our major suppliers’ manufacturing facilities are located near major earthquake faults. One of the foundries we use is located in Taiwan, which has suffered severe earthquakes in the past. We have not experienced significant disruption to our operations due to earthquakes in the past. However, if a major earthquake or other natural disaster were to affect our suppliers, our sources of supply could be interrupted, which would seriously harm our business.

We lease approximately 66,300 square feet of space in San Jose, California in which our headquarters, technology and product development and testing facilities are located. Approximately 53,400 square feet of this facility is leased through July 2004, with renewal options. The remaining 12,900 square feet of this space is leased through May, 2005, with renewal options and is unoccupied. In fiscal 2001 and 2003 there were restructuring charges of $522,000 and $1,431,000, respectively, related to this unused leased facility. We also have North American sales offices located in California, Texas, Illinois, and North Carolina as well as International sales offices in Taiwan, Korea, Japan, Singapore and the United Kingdom. We believe our current facilities are adequate to support our needs through the end of fiscal 2004.

The Company is subject to various routine claims and legal proceedings that arise in the ordinary course of business. The Company is presently not subject to any legal proceedings that could have a material impact on its business or financial condition.

No matters were submitted to a vote of security holders during the fourth quarter of the fiscal year covered by this report.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION

AND RESULTS OF OPERATIONS

This Annual Report includes “forward-looking statements” within the meaning of Section 27A of the Securities Act if 1933, as amended and Section 21E of the Securities Exchange Act of 1934, as amended. All statements other than statements of historical fact are “forward-looking statements” for purposes of these provisions, including any statements regarding projections of earnings, revenues or other financial items; plans and objectives of management for future operations; future expenditures; proposed new products or services and their development schedule; industry, technological or market trends, our ability to address the need for application specific logic products; our ability to respond rapidly to customer needs; expanding product sales; future economic conditions or performance, and any statement of assumptions underlying any of the foregoing. In some cases, forward-looking statements can be identified by the use of terminology such as “may,” “will,” “expects,” “plans,” “anticipates,” “estimates,” “potential,” or “continue,” or the negative thereof or other comparable terminology. Although we believe that the expectations reflected in the forward-looking statements contained herein are reasonable, there can be no assurance that such expectations or any of the forward-looking statements will prove to be correct, and actual results could differ materially from those projected or assumed in the forward-looking statements. Some of the factors that could cause our actual results to differ materially are set forth herein under the heading “Risk Factors” and elsewhere in this report. All forward-looking statements and reasons why results may differ included in this Annual Report are made as of the date hereof, and we assume no obligation to update any such forward-looking statement or reason why actual results may differ.

CRITICAL ACCOUNTING POLICIES

Our consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of such statements requires us to make estimates and assumptions that affect the reported amounts of revenues and expenses during the reporting period and the reported amounts of assets and liabilities as of the date of the financial statements. Our estimates are based on historical experience and other assumptions that we consider to be reasonable given the circumstances. Actual results may vary from our estimates.

We consider the following accounting policies are “critical” as defined by the Securities and Exchange Commission, in that they are both highly important to the portrayal of our financial condition and results, and require us to make difficult judgements and assumptions about matters that are inherently uncertain. We also have other important policies that are discussed in Note 1 to the Consolidated Financial Statements.

REVENUE RECOGNITION. We recognize revenue from the sale of our products upon shipment, provided title and risk of loss has passed to the customer, the fee is fixed and determinable and collection of the revenue is reasonably assured. A provision for estimated future returns and other charges against revenue is recorded at the time of shipment. Approximately 59% of our sales are to distributors. We have agreements for price adjustment and stock rotation programs with our distributors. The revenue we record for sales to our distributors is net of estimated provisions for these programs. When determining this net revenue, we must make significant judgements and estimates. Our estimates are based on historical experience rates, inventory levels in the distribution channel, current trends and other related factors. However, because of the inherent nature of estimates, there is a risk that there could be significant differences between actual amounts and our estimates. Our financial condition and operating results depend on our ability to make reliable estimates and we believe that our estimates are reasonable.

INVENTORIES. Inventories are recorded at the lower of standard cost (which generally approximates actual cost on a first-in, first-out basis) or market value. We record charges for excess and obsolete inventory based on inventory age, shipment history and our forecast of demand over a specific future period

25

Table of Contents

of time. Actual market conditions in the volatile semiconductor markets that we serve may vary from our forecast or other assumptions, potentially impacting our assessment of excess and obsolete inventory resulting in material effects on our gross margin.

INVESTMENTS. Pericom adopted SFAS No. 142, Goodwill and Other Intangible Assets, for its fiscal year beginning July 1. 2001. Accordingly, we ceased amortizing goodwill with a net carrying value of $1,323,000 and annual amortization of $338,000 that resulted from business combinations initiated prior to the adoption of SFAS No. 141, Business Combinations. SFAS No. 142 also requires that goodwill be tested for impairment at least annually. We determined that no impairment of this goodwill existed in fiscal 2003, and we will continue to evaluate such goodwill at least annually.

We also made other investments in fiscal 2003 including bridge loans convertible to equity as well as direct equity investments. These investments are included in other long-term assets in our balance sheet and are carried at the lower of cost, or market if the investment has experienced an other than temporary decline in value. We monitor these investments quarterly and make appropriate reductions in carrying value if a decline in value is deemed to be other than temporary.

OVERVIEW

Pericom Semiconductor Corporation was incorporated in June 1990. We completed our first profitable fiscal year on June 30, 1993. We design, manufacture and market high performance digital, analog and mixed-signal integrated circuits used for the transfer, routing, and timing of digital and analog signals within and between computer, networking, data communications and telecommunications systems. Our first volume sales occurred in fiscal 1993 and consisted exclusively of 5-volt 8-bit interface logic circuits. Since then we have expanded our product offering by introducing the following products, among others:

26

Table of Contents

As is typical in the semiconductor industry, we expect selling prices for our products to decline over the life of each product. Our ability to increase net revenues is highly dependent upon our ability to increase unit sales volumes of existing products and to introduce and sell new products in quantities sufficient to compensate for the anticipated declines in selling prices of existing products. We seek to increase unit sales volume through increased wafer fabrication capacity allocations from our existing foundries, qualification of new foundries, increased number of die per wafer through die size reductions and improved yields of good die through the implementation of advanced process technologies, but there can be no assurance that we will be successful in these efforts. In fiscal 2003, 2002 and 2001, respectively, approximately 72%, 68%, and 59% of the wafers for our semiconductor products were manufactured by Chartered Semiconductor Manufacturing. We qualified AMS as a wafer supplier in fiscal 1991, NJRC in fiscal 1995, TSMC in fiscal 1997 and Hyundai/Hynix in 1998.

Declining selling prices will adversely affect gross margins unless we are able to offset such declines with the sale of new higher margin products or achieve commensurate reductions in unit costs. We seek to improve our overall gross margin through the development and introduction of selected new products that we believe will ultimately achieve higher gross margins. A higher gross margin for a new product is typically not achieved until some period after the initial introduction of the product—after start-up expenses for that product have been incurred and once volume production begins. In general, costs are higher at the introduction of a new product due to the use of a more generalized design schematic, lower economies of scale in the assembly phase and lower die yield. Our ability to decrease unit cost depends on our ability to shrink the die sizes of our products, improve yields, obtain favorable subcontractor pricing, and make in-house manufacturing operations more productive and efficient. There can be no assurance that these efforts, even if successful, will be sufficient to offset declining selling prices.

RESULTS OF OPERATIONS

The following table sets forth certain statement of operations data as a percentage of net revenues for the periods indicated.

COMPARISON OF FISCAL 2003, 2002 AND 2001

NET REVENUES. Net revenues decreased 5.5% from $47.6 million in fiscal 2002 to $45.0 million in fiscal 2003. The decrease in net revenues resulted primarily from a rapid decline in weighted average selling prices and continued reductions of inventory levels in the distribution and contract manufacturing sales channels. Net revenues decreased 56.0% from $108.3 million in fiscal 2001 to $47.6 million in fiscal 2002. The decrease in net revenues from fiscal 2001 to fiscal 2002 resulted primarily from the prolonged worldwide semiconductor industry downturn and a decline in the weighted average selling prices of our products. The rapid semiconductor industry downturn that began in fiscal 2001 also caused an over-supply of inventories in the global distribution and contract manufacturing sales channels. This inventory imbalance pushed order rates down, caused a corresponding drop in backlog and caused the percentage of net sales represented by orders placed and shipped in the same quarter to grow. These orders are called “turns” orders. With reduced backlog and increased reliance on turns orders, there is more uncertainty in the Company’s ability to predict near-term revenue levels.

GROSS PROFIT. Gross profit decreased slightly from $13.7 million in fiscal 2002 to $13.5 million in fiscal 2003. Gross margin increased slightly from 28.8% in fiscal 2003 to 30.0% in fiscal 2003. The slight increase in gross margin was largely due to significant nonrecurring inventory write-downs recorded in fiscal 2002. The level of inventory reserves recorded in fiscal 2003 was significantly less than in fiscal 2002. Excluding the inventory reserve charges in fiscal 2002, product margins actually declined from fiscal 2002 to fiscal 2003 due primarily to declines in weighted average selling prices. Gross profit decreased 70.2% from $46.0 million in fiscal 2001 to $13.7 million in fiscal 2002. Gross margin decreased from 42.4% in fiscal 2001 to 28.8% in fiscal 2002. The decrease in gross margin resulted from decreases in the average selling prices of our various product lines and from under-absorption of factory overhead due to reduced unit volumes. These decreases were partially offset by cost reductions achieved through reduced wafer, assembly and test costs. Future gross profit and gross margins are highly dependent on the amount and product mix of turns orders. Because of this, the Company is not able to predict future gross profit levels or gross margins with certainty.

RESEARCH AND DEVELOPMENT. Research and development expenses decreased 3.4% from $11.7 million in fiscal 2002 to $11.3 million in fiscal 2003. Research and development expenses increased 6.4%

28

Table of Contents

from $11.0 million in fiscal 2001 to $11.7 million in fiscal 2002. As a percentage of net revenues, research and development increased from 24.5% in fiscal 2002 to 25.2% in fiscal 2003. In 2003 we continued our commitment to new product development and at the same time realized certain efficiencies that resulted in a slight decrease in absolute dollars of research and development spending as compared with 2002. As a percentage of net revenues, research and development increased from 10.1% in fiscal 2001 to 24.5% in fiscal 2002. The increase in absolute dollars in research and development spending from fiscal 2001 to fiscal 2002 was primarily attributable to development costs for new products in each of our product lines and, to a lesser extent, expansion of engineering staff and related infrastructure. We believe that continued investment in research and development is critical to attaining our strategic objectives, and as a result we expect research and development expenses to increase in absolute dollars in future periods.

SELLING, GENERAL AND ADMINISTRATIVE. Selling, general and administrative expenses consist primarily of personnel and related overhead costs for sales, marketing, finance, human resources and general management. Selling, general and administrative expenses decreased 4.2% from $11.8 million in fiscal 2002 to $11.3 million in fiscal 2003 but increased as a percentage of sales from 24.7% in fiscal 2002 to 25.1% in fiscal 2003. The expense decrease was primarily due to decreased staffing levels. Selling, general and administrative expenses decreased 22.4% from $15.2 million in fiscal 2001 to $11.8 million in fiscal 2002, but increased as a percentage of sales from 14.0% in fiscal 2001 to 24.7% in fiscal 2002. The expense decrease was primarily due to decreased staffing levels and decreases in commissions and other incentives resulting from the decline in sales and profitability.

The Company anticipates that selling, general and administrative expenses will increase in future periods over the long term due to increased staffing levels, particularly in sales and marketing, as well as increased commission expense to the extent the Company achieves higher sales levels. In the short term, the Company intends to continue to focus on controlling costs until business conditions improve. If business conditions deteriorate or the rate of improvement does not meet our goals, the Company may implement further cost-cutting actions.

RESTRUCTURING CHARGE. In fiscal 2003 there was a restructuring charge of $1.4 million related to an unused leased facility. This restructuring charge is sufficient to cover the costs of the facility through the term of the lease. There was also a restructuring charge of $522,000 in fiscal 2001 related to the same facility. There were no restructuring charges in fiscal 2002.

OTHER INCOME, NET. Other income, net includes interest income and expense, investment write-offs and our allocated portion of net losses of Pericom Technology, Inc. (“PTI”), a British Virgin Islands corporation based in Shanghai, People’s Republic of China. PTI was formed by Pericom and certain Pericom shareholders in 1994 to develop and market semiconductors in China and certain other Asian countries (see Note 4 of Notes to Financial Statements). Other income, net increased from $1.5 million in fiscal 2002 to $3.5 million in fiscal 2003. Interest income decreased from $5.6 million in fiscal 2002 to $5.2 million in fiscal 2003 primarily due to declines in short term interest rates. Our share in the net losses of PTI decreased from $1.4 million in fiscal 2002 to $739,000 in fiscal 2003 as the market conditions in China have improved. In addition, we wrote off investments totaling $1.0 million in fiscal 2003. Other income, net decreased from $7.9 million in fiscal 2001 to $1.5 million in fiscal 2002. Interest income decreased from $8.3 million in fiscal 2001 to $5.6 million in fiscal 2002 primarily due to declines in short-term interest rates. Our share in the net losses of PTI increased from $68,000, excluding $331,000 in goodwill amortization, in fiscal 2001 to $1.4 million in fiscal 2002 as PTI’s losses increased due to the global semiconductor industry downturn. In addition, we wrote off $2.7 million in investments in fiscal 2002. No investments were written off in fiscal 2001.

PROVISION FOR INCOME TAXES. The income tax benefit in fiscal 2003 was $2.8 million as compared with a benefit of $3.0 million in fiscal 2002. The income tax benefit in fiscal 2002 was $3.0 million as compared with a provision of $9.8 million in fiscal 2001. The income tax benefit in fiscal 2002 and fiscal 2003 were the result of the carry back of the net loss in each year to prior fiscal years. The provision for income taxes differed from the federal statutory rate primarily due to state income taxes, the utilization of research and development tax credits and a change in the deferred asset valuation allowance.

LIQUIDITY AND CAPITAL RESOURCES

Operating activities provided approximately $2.2 million in cash in fiscal 2003, $9.1 million in cash in fiscal 2002 and $19.4 million in fiscal 2001. The decrease in cash flows provided by operating activities in fiscal 2003 from fiscal 2002 was primarily due to inventories increasing by $624,000 in fiscal 2003 while inventories decreased $5.1 million in fiscal 2002. The decrease in cash flows provided by operating activities in fiscal 2002 from fiscal 2001 was primarily due to the net loss of $5.3 million for fiscal 2002 compared to net income of $17.4 million for fiscal 2001. For fiscal 2003 our cash flows provided by operating activities were the result of the net loss of $4.3 million as offset by depreciation and amortization of $3.9 million, investment write offs of $1.2 million, our share of the net loss of PTI of $739,000, a decrease of $1.6 million in accounts receivable, an increase of $624,000 in inventory and an increase in accrued liabilities of $904,000.

Net cash used for investing activities was $4.7 million, $87.4 million and $57.0 million in fiscal 2003, 2002 and 2001, respectively. The decrease in net cash used for investing activities from fiscal 2002 to fiscal 2003 was primarily due to net purchases of short-term investments decreasing from a net purchase of $81.0 million in fiscal 2002 to a net maturity of $5.4 million in fiscal 2003. The increase in net cash used for investing activities from fiscal 2001 to 2002 was primarily due to net purchases of short-term investments increasing from $45.5 million in fiscal 2001 to $81.0 million in fiscal 2002. We made capital expenditures of approximately $1.8 million in fiscal 2003, $2.2 million in fiscal 2002 and $5.8 million in fiscal 2001.

Financing activities used $514,000 in cash in fiscal 2003 and provided approximately $1.9 million in cash in fiscal 2002 and $2.5 million in fiscal 2001. In fiscal 2003, net cash used in financing activities resulted from the repurchase of common stock offset in part by the issuance of common stock from employee stock plans. In fiscal 2002 and 2001, cash flows from financing activities resulted from the issuance of common stock, from employee stock plans.

Our cash, cash equivalents and short-term investments decreased by $6.8 million to $149.0 million on June 30, 2003 from $155.8 million on June 30, 2002. The decrease was primarily due to our investment in Saronix LLC. We believe that cash generated from operations and existing cash balances will be sufficient to fund necessary purchases of capital equipment and leasehold improvements, to fund our repurchase of common stock and to provide working capital at least through the next 12 months. However, there can be no assurance that future events will not require us to seek additional capital sooner or, if so required, that adequate capital will be available at all or on terms acceptable to us.

Our Board of Directors has approved the repurchase of up to 2,000,000 shares of common stock. As of September 8, 2003, we have repurchased 274,500 shares at a cost of approximately $2.2 million.

A portion of our cash may be used to acquire or invest in complementary businesses or products or to obtain the right to use complementary technologies. From time to time, in the ordinary course of business, we may evaluate potential acquisitions of such businesses, products or technologies. For example, we have signed a definitive purchase option agreement to acquire the net assets of privately held Saronix LLC. The purchase price is expected to be under $10 million, much of which has been advanced to Saronix in the form of convertible secured loans.

RECENTLY ISSUED ACCOUNTING STANDARDS

In June 2001, the FASB issued SFAS No. 142, “Goodwill and Other Intangible Assets”. SFAS No. 142 addresses the initial recognition and measurement of intangible assets acquired outside of a business combination and the accounting for goodwill and other intangible assets subsequent to their acquisition. SFAS No. 142 provides that intangible assets with finite useful lives be amortized and that goodwill and intangible assets with indefinite lives will not be amortized, but will rather be tested at least annually for impairment. Pericom adopted SFAS No. 142 for its fiscal year beginning July 1, 2001. On that date, we ceased amortizing goodwill with a net carrying value of $1,323,000 at June 30, 2001 and annual amortization of $338,000 that resulted from business combinations initiated prior to the adoption of SFAS 141, Business Combinations. We determined that no impairment of this goodwill existed in fiscal 2003. We will continue to evaluate such goodwill at least annually.

In August 2001, the FASB issued SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets”. SFAS No. 144 addresses financial accounting and reporting for the impairment or disposal of long-lived assets. It superseded SFAS No. 121, Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed of, and the accounting and reporting provisions of Accounting Principles Board No. 30, Reporting the Results of Operations—Reporting the Effects of Disposal of a Segment of a Business and Extraordinary, Unusual and Infrequently Occurring Events and Transactions for the disposal of a segment of a business. We adopted SFAS No. 144 on July 1, 2002. The adoption of SFAS No. 144 had no effect on our results of operations, financial position or liquidity.

Table of Contents

In April 2002, the FASB issued SFAS No. 145, “Rescission of FASB Statement No. 4, 44, and 64, Amendment of FASB Statement No. 13, and Technical Corrections”. SFAS 145 requires that any gains or losses on extinguishment of debt that were classified as an extraordinary item in prior periods that are not unusual in nature and infrequent in occurrence be reclassified to other income (expense), beginning in fiscal 2003, with early adoption encouraged. We adopted SFAS No. 145 on July 1, 2002. The adoption of SFAS No. 145 had no effect on our results of operations or financial position.

In June 2002, the FASB issued SFAS No. 146, “Accounting for Costs Associated with Exit or Disposal Activities”, which addresses accounting for restructuring and similar costs. SFAS No. 146 supersedes previous accounting guidance, principally Emerging Issues Task Force Issue No. 94-3. SFAS No. 146 requires that the liability for costs associated with an exit or disposal activity be recognized when the liability is incurred. Under Issue 94-3, a liability for an exit cost was recognized at the date of our commitment to an exit plan. SFAS No. 146 also establishes that the liability should initially be measured and recorded at fair value. Accordingly, SFAS No. 146 may affect the timing of recognizing future restructuring costs as well as the amounts recognized. We adopted SFAS No. 146 on January 1, 2003. The adoption of SFAS No. 146 had no effect on our results of operations or financial position.

In November 2002, the FASB issued FASB Interpretation No. (FIN) 45, “Guarantor’s Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others.” FIN 45 requires that upon issuance of a guarantee, the guarantor must recognize a liability for the fair value of the obligation it assumes under that guarantee. The provisions for initial recognition and measurement are effective on a prospective basis for guarantees that are issued or modified after December 31, 2002, irrespective of a guarantor’s year-end. The disclosure requirements of FIN 45 were effective for interim and annual periods ending after December 15, 2002, and are applicable to our product warranty liability and other guarantees. We adopted the provisions of FIN 45 for guarantees issued or modified after December 31, 2002, and the adoption of FIN 45 did not have a material impact on our results of operations or financial position.

In December 2002, the FASB issued SFAS 148, “Accounting for Stock-Based Compensation—Transition and Disclosure,” which amends SFAS 123, “Accounting for Stock-Based Compensation.” SFAS 148 provides alternative methods of transition for an entity that voluntarily changes to the fair value based method of accounting for stock-based employee compensation. It also amends the disclosure provisions of SFAS 123 to require prominent disclosure about the effects an entity’s accounting policy decisions with respect to stock-based employee compensation on reported net income in both annual and interim periods. SFAS 148 is effective for annual periods ending after December 15, 2002 and interim periods beginning after December 15, 2002. We adopted the disclosure requirements of SFAS 148 effective March 31, 2003 and continue to account for stock based compensation under APB Opinion 25 and related Interpretations. The adoption of the disclosure requirements of SFAS 148 did not have a material impact on our results of operations or financial position.

In January 2003, the FASB issued FIN 46, “Consolidation of Variable Interest Entities.” FIN 46 establishes accounting guidance for consolidation of a variable interest entity (VIE), formerly referred to as special purpose entities. FIN 46 applies to any business enterprise, both public and private, that has a controlling interest, contractual relationship or other business relationship with a VIE. FIN 46 provides guidance for determining when an entity (the Primary Beneficiary) should consolidate a VIE that functions to support the activities of the Primary Beneficiary. We have no contractual relationship or other business relationship with a VIE, and therefore the adoption will not have an effect on our consolidated results of operations or financial position.

MARKET RISK DISCLOSURE

At June 30, 2003, our investment portfolio consisted of fixed income securities, excluding those classified as cash equivalents, of $139.3 million (see Note 1 of Notes to Financial Statements). These securities are

32

subject to interest rate risk and will decline in value if market interest rates increase. Due to the short duration and conservative nature of these instruments, we do not believe that we have a material exposure to interest rate risk. For example, if market interest rates were to increase immediately and uniformly by 10% from levels as of June 30, 2003, the decline in the fair value of the portfolio would not have a material effect on our results of operations over the next fiscal year.

INDEPENDENT AUDITORS’ REPORT

To the Board of Directors and Shareholders of

Pericom Semiconductor Corporation:

We have audited the accompanying balance sheets of Pericom Semiconductor Corporation (the “Company”) as of June 30, 2003 and 2002, and the related statements of operations, shareholders’ equity and comprehensive income, and cash flows for each of the three years in the period ended June 30, 2003. 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 auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such financial statements present fairly, in all material respects, the financial position of Pericom Semiconductor Corporation at June 30, 2003 and 2002, and the results of its operations and its cash flows for each of the three years in the period ended June 30, 2003, in conformity with accounting principles generally accepted in the United States of America.

Our audits were conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. The financial statement schedule listed in Item 14(a)(2) is presented for the purpose of additional analysis and is not a required part of the basic financial statements. This financial statement schedule is the responsibility of the Company’s management.
