PART I

OVERVIEW

We design, manufacture and sell digital video systems and fiber optic systems that enable network operators to provide a range of interactive and advanced digital services that include digital video, video-on-demand (VOD), high definition television (HDTV), high-speed Internet access and telephony. Historically, most of our sales have been derived from sales of digital headend products and fiber optic transmission systems to cable television and direct broadcast satellite (DBS) operators. We also derive a growing portion of our sales from telephone companies that offer video services to their customers.

Harmonic was initially incorporated in California in June 1988 and reincorporated into Delaware in May 1995. Our principal executive offices are located at 549 Baltic Way, Sunnyvale, California 94089. Our telephone number is (408) 542-2500. Harmonic is organized as two operating divisions, Convergent Systems, or CS, for digital video systems, and Broadband Access Networks, or BAN, for fiber optic systems. Each division has its own management team directing its product development and marketing strategies and its customer service requirements. A separate sales force generally supports both divisions with appropriate product and market specialization as required.

INDUSTRY OVERVIEW

Demand for broadband and digital video services

The demand for broadband services has increased significantly in recent years due in large part to the dramatic growth of the Internet. In addition, the delivery to subscribers of television programming and Internet-based information and communication services is converging, driven in part by advances in technology and in part by changes in the regulatory and competitive environment. The demand for more bandwidth-intensive video, voice and data content has strained existing communications networks and created bottlenecks, especially in the “last mile” of the communications infrastructure where homes connect to the local network. Changes in the television industry have led to a proliferation of new television channels, including the introduction of high definition channels, and to the development of interactive and on-demand television services which are provided on an individual, as opposed to a broadcast basis.

Recent regulatory reform has spurred competition among communication service providers worldwide to offer combinations of video, voice and data services. Historically, U.S. long distance carriers and regional Bell operating companies, or RBOCs, provided only telephony services in the residential market. Cable television multiple system operators, or MSOs, provided video programming. DBS operators previously provided only video programming services and were initially further restricted by regulation from making local television channels available in local markets. As a result, none of these operators had networks conducive to providing high-speed data services to residential subscribers, or any other services that they had not been previously allowed to provide. The Telecommunications Act of 1996, however, generally permitted service operators to enter each other’s markets and to provide a variety of voice, video and data services. As a result, most cable companies now offer broadband services, including broadcast digital video, VOD, internet access and telephony, over many of their cable systems. Similarly, telephone companies, or telcos, have deployed various digital subscriber line, or DSL, technologies for high-speed data services over their existing copper networks. A number of telcos have begun to deploy alternative delivery systems such as fiber to the premises, or FTTP, for data and video transmission, and some have also deployed video services over their DSL networks. Following regulatory changes, DBS operators have now introduced local channels in all major markets, allowing them to compete more effectively with cable MSOs. Additionally, in many major metropolitan areas, new carriers have entered the communications services market, although many scaled back or halted network construction because of funding limitations caused by conditions in capital markets.

Similar deregulation of telecommunications and broadcasting abroad has fostered substantial growth and competition in foreign communications markets. Many countries have liberalized the provision of broadcast television and abolished or exposed to competition incumbent broadcast and telecom monopolies. Several have encouraged digital broadcasting in order to provide more channel capacity, higher quality video, and the provision of other digital services, such as data and voice. These developments have led to the establishment of new cable television networks, the launch of new DBS services and the entry of telephone companies into the business of providing video services.

Our cable market

To address increasing competition and demand for high-speed broadband services, cable operators have introduced digital video, voice and data services in addition to traditional analog video. By offering bundled packages of broadband services, cable operators are seeking to obtain a competitive advantage over telephone companies and DBS providers and to create additional revenue streams. Cable operators have been upgrading and rebuilding their networks to offer digital video, which enables cable operators to provide more channels and better picture quality than analog video, allowing them to better compete against the increasing penetration of DBS services. In many areas, cable operators have rolled out new interactive services such as VOD, as well as HDTV on their digital platforms. VOD allows subscribers to order, start, pause and stop selected movies and other content at their own discretion. In order to provide high-speed Internet service, cable operators have deployed cable modems in an increasing number of their systems. According to the National Cable & Telecommunications Association, there were an estimated 19.4 million cable modem subscribers in the U.S. as of September 30, 2004. Some cable operators are also upgrading and building out their networks to provide telephony services in a number of major markets and some have also targeted certain business markets for the delivery of high-bandwidth services.

The ability of cable operators to deliver digital video, voice and high-speed data services on a broad scale, however, was constrained by the design of their legacy networks. These networks, which reach more than 90% of U.S. homes with televisions, were built initially for one-way broadcast analog television and have required substantial upgrades to make them capable of reliably supporting two-way digital services, such as high-speed Internet access and telephony. Major U.S. cable operators have indicated that the completion of major network upgrades, which involved significant labor and construction costs, which will result in lower capital expenditures in future periods. However, in addition to upgrading and extending network infrastructure with fiber optics, in order to provide new services it is necessary for cable operators to invest in digital headend equipment that can receive, process and distribute content from a variety of sources in increasingly complex headends. For example, VOD services require video storage equipment and servers, complemented by devices capable of routing, multiplexing and modulation for delivering signals to individual subscribers over a hybrid fiber-coax, or HFC, network. Additionally, the provision of HDTV

Our satellite market

Satellite operators around the world have established digital television services that serve millions of subscribers. These services, which are capable of providing up to several hundred channels of high quality video, have become popular with consumers who want a wider choice of programming than has been typically available from cable or broadcast television. The increasing availability of digital set top boxes and small low cost receiving dishes for subscribers’ homes facilitated the rollout of DBS services. DBS services, however, operate mostly in a one-way environment. Signals are transmitted from an uplink center to a satellite and then beamed to dishes located at subscribers’ homes. This method is suited to the delivery of broadcast television, but does not lend itself easily to two-way services, such as Internet access or VOD.

As cable operators expand the number of channels offered and introduce services such as VOD and HDTV, DBS providers are seeking to protect and expand their subscriber base in a number of ways. DBS operators now have the right to provide local channels to local markets in the U.S. and have made local channels available in all major markets. In the U.S., “must-carry” regulations generally require DBS operators to transmit all local channels in any markets they serve, thereby adding constraints on channel capacity. Advances in digital compression technology allow DBS operators to cost-effectively add these new channels and to further expand their video entertainment offerings, although the need to provide more HDTV channels in the future will pose continuing bandwidth challenges and may require further capital expenditures by such operators.

Our telco market

Telcos are also facing increasing competition and demand for high-speed residential broadband services. To date, their offerings in residential markets have been aimed mostly at providing Internet access in addition to traditional voice services. This is accomplished principally by the deployment of DSL technology or, in certain cases, over FTTP networks. Like the cable networks, the telcos’ legacy networks are not well equipped to offer new services. The substantial bandwidth and distance limitations of the copper-based “last mile” have limited DSL deployment and present an even greater barrier to providing video services. Although cable companies and certain new broadband service providers have networks equipped to deliver video and are moving to capture data and voice customers, relatively few telcos have to date offered video services as a competitive response. Video delivered over DSL lines has major bandwidth limitations, but the use of video compression technology at very low bit rates and improvements in DSL technology has allowed certain operators to introduce video services. The major RBOCs have now begun to implement plans to rebuild or upgrade their networks to offer bundled video, voice and data services.

Other markets

In the terrestrial broadcasting market, operators in many countries are now required by regulation to convert from analog to digital transmission in order to free up the broadcast spectrum. The conversion to digital transmission often provides the opportunity to deliver new services, such as HDTV and data transmission. These broadcasters are faced with similar requirements to cable and satellite providers in that they need to convert analog signals to digital prior to transmission and must also effectively manage the available bandwidth to maximize their revenue streams. Similarly, operators of wireless broadcast systems require encoding for the conversion of analog signals to digital.

The construction of new networks or the upgrade and extension of existing networks to facilitate high-speed broadband video, voice and data services requires substantial expenditure and often the replacement of significant portions of the existing infrastructure. The economic success of incumbent and new operators in a competitive environment will depend to a large extent on their ability to offer a choice of attractively priced packages of voice, video and data services to consumers, and to do so with high reliability and easy access to their network. Personalized video services, such as VOD, and the availability of TV sets equipped for HDTV, will require increasing amounts of bandwidth to the home in order to deliver maximum choice and flexibility. In addition, certain operators have initiated trials to deliver live television to cellular telephones and other mobile devices. Compression of video and data to utilize effectively the available bandwidth, the cost-effective transport of digital traffic within networks, and the construction of robust “fat pipes” for distribution of content are all essential elements in the ability of operators to maximize revenue and minimize capital expenditures and operating costs.

Current industry conditions

The telecommunications industry was particularly impacted by the recent economic recession, adverse conditions in capital markets and financial difficulties in both the service and equipment sectors, including bankruptcies. Many of our domestic and international customers accumulated significant levels of debt and have begun or completed reorganizations and financial restructurings. In particular, Adelphia Communications, a major domestic cable operator, declared bankruptcy in June 2002. The stock prices of other domestic cable companies came under pressure following the Adelphia bankruptcy due to concerns about debt levels and capital expenditure requirements for new and expanded services, thereby making the raising of capital more difficult and expensive. In Europe, rapid consolidation of the cable industry through acquisitions also led to significant levels of debt at the major MSOs, and companies such as NTL and UPC went through bankruptcy proceedings. European digital broadcasters, such as ITV Digital, Kirsch and Quiero, also filed for protection from creditors. We believe that the financial condition of many of our customers has stabilized or improved, but industry capital spending has not returned to levels seen in 1999 and 2000. Furthermore, it is likely that continuing industry restructuring will take place via mergers or spin-offs, such as the Comcast acquisition of AT&T Broadband in 2002, the acquisition by The News Corporation Ltd. in 2003 of an indirect controlling interest in Hughes Electronics, the parent company of DIRECTV, and other more recent transactions, such as the privatization of Cox Communications, the proposed sale of Adelphia out of bankruptcy, and the proposed sale of Cablevision’s VOOM! satellite assets to Echostar. Regulatory issues, financial concerns and business combinations among our customers are likely to significantly affect the industry, capital spending plans, and our business for the foreseeable future.

PRODUCTS

Harmonic’s products are organized in two principal groups, Convergent Systems and Broadband Access Networks. In addition, Harmonic provides technical support services to its customers worldwide.

Our digital video products provide broadband operators with the ability to accept a variety of signals from different sources, in different protocols, and to organize, manage and distribute this content to maximize use of the available bandwidth. Our encoders and multiplexers allow our customers to convert analog video to digital and to process this output into a compressed video stream which can be delivered over a fiber or wireless network to subscribers. Our edge device, or gateway, products enable operators to deliver customized broadcast or narrowcast on-demand services to their subscribers.

Our optical transmission products, node platforms and return path products, and element management systems allow operators to deliver traditional broadcast video services while supporting the roll-out of emerging interactive services and managing the fiber network. Various types of optical transmitters enable operators to design network architectures which address the service and technical requirements of their systems. Our optical nodes are designed to incorporate a variety of modules which provide the operator with network flexibility and scalability to support increases in subscribers and the introduction of new services.

The Convergent Systems (CS) division develops standards-based solutions that enable operators to increase the capacity of their broadband networks with advanced compression and stream processing technology. Our CS division’s advanced digital video solutions enable satellite, cable, telco, broadcast, and wireless operators around the world to offer digital video services to their customers. As video, data and voice services continue to converge, effectively managing and processing these bandwidth-intensive applications becomes critical to the long-term viability of an operator’s network.

Compression products

DiviCom encoders. This is a complete line of high performance encoders, which provide compression of video, audio and data channels. Using sophisticated signal pre-processing, noise reduction and encoding algorithms, these encoders produce high-quality video and audio at low data rates. Their compliance with widely adopted standards enables interoperability with other products and systems. The MV100 encoder, introduced in the fall of 2003, has the highest compression efficiency of our encoder family and is designed with sufficient processing power to function with new video compression standards currently being introduced. The MV450 encoder is designed for encoding of high definition television signals.

Ion multichannel encoders. Introduced in 2004, the Ion encoder is a modular encoder designed for lower cost, higher density applications. Up to four encoder modules can be inserted into a single rack unit.

Edge devices

Narrowcast Services Gateway. Our Narrowcast Services Gateway, or NSG, is a fully integrated server gateway, which interfaces with the output from a video server and integrates routing, multiplexing and modulation into a single package for the delivery of VOD services to subscribers over cable networks. The NSG is usually supplied with Gigabit Ethernet inputs, allowing the operator to use bandwidth efficiently by delivering IP signals from the headend to the edge of the network for subsequent modulation onto the HFC network.

Stream processing products

Media Node. Media Node is a flexible MPEG-2 networking, switching and multiplexing platform. In a broadcast facility, the video, audio and data streams must be combined or multiplexed into a single stream prior to transmission. Our multiplexing platform combines compressed streams from various sources into a single transport stream. Sources may include Harmonic encoders or third-party devices such as video servers.

Broadcast Network Gateway. Our Broadcast Network Gateway, or BNG, provides digital turnaround and remote modulation capability with a variety of flexible input and output options. The BNG allows operators to manage a variety of digital streams without expensive decoding and re-encoding.

Digital turnaround systems. Our digital turnaround system is a flexible, modular platform for aggregating, multiplexing and scrambling digital signals prior to transmission over broadband networks. It is especially well suited to “grooming” applications where a local operator wants to change a line-up of pre-packaged channels or content received from a regional or national feed. We also provide the Terayon “CherryPicker” digital stream management system under a reseller agreement with Terayon Communications.

Control and automation products

Modern digital networks are a diverse array of hardware and software components from a variety of vendors, using a number of network protocols and standards. Network management is a key tool that lets service providers monitor and control their networks. Our expertise in digital video, audio and data helps service providers with their network management requirements. Products such as our NMX Digital Service Manager give service providers the ability to visually monitor their digital video infrastructure at an aggregate level, rather than just discrete pieces of hardware, reducing their operational costs.

The Broadband Access Networks (BAN) division applies its strengths in optics and electronics, including expertise with lasers, modulators, and radio frequency technology, to develop products which provide enhanced network reliability and allow broadband service providers to deliver advanced services, including two-way interactive services. We provide the operator with end-to-end capability in the fiber portion of the network.

Optical transmission systems

We offer MAXLink transmitters and optical amplifiers, PWRLink transmitters and Dense Wave Division Multiplexing, or DWDM, and Coarse Wave Division Multiplexing, or CWDM, systems for a wide range of optical transmission requirements.

MAXLink transmitters and optical amplifiers. The MAXLink transmitters and optical amplifiers operate at a wavelength of 1550 nm and serve long-haul applications and fiber dense architectures that are beyond the capability of shorter range 1310 nm transmitters. This system is suited to cable networks employing such features as redundant rings, hub interconnects and broadcast layer transmission. The MAXLink Plus further increases the channel capacity of cable and other networks and can transmit over distances in excess of 200 kilometers. Certain models of these optical transmitters and amplifiers are also used in passive optical networks by telephone companies and other broadband providers offering broadcast video services.

PWRLink transmitters. The PWRLink series of optical transmitters provides optical transmission primarily for use at a headend or hub for local distribution to optical nodes and for narrowcasting, which is the transmission of programming to a select set of subscribers.

METROLink system. Our METROLink DWDM system allows operators to expand the capacity of a single strand of fiber and also to provide narrowcast services directly from the headend to nodes. This ability can significantly reduce the size of hubs and the associated building and equipment maintenance costs. By increasing the downstream and upstream capacity of existing optical fiber, METROLink can also eliminate the significant expense of laying additional fiber.

GIGALight. Our GIGALight is a DWDM system for the transport of Gigabit Ethernet traffic. It allows high-bandwidth services, such as VOD, to be carried on a single fiber and targeted to particular segments of the network by optical wavelength.

CWDM Commercial Services. Our CWDM Commercial Services solution allows a cable operator to leverage his existing HFC network by providing high-speed services on a wavelength of a shared fiber to individual business customers.

Optical nodes and return path products

We offer a variety of optical nodes, return path transmitters and receivers to provide two-way transmission capability. Optical nodes are designed to allow the customer to add capacity and scale as the number of subscribers grows and new services are provided.

PWRBlazer optical nodes. Our family of PWRBlazer optical nodes supports network architectures which meet the varying demands for bandwidth delivered to a service area. By the addition of modules providing functions such as return path transmission and DWDM, our configurable nodes are easily segmented to handle increasing two-way traffic over a fiber network without major plant reconstruction.

Return path transmitters and receivers. Our return path transmitters support two-way transmission capabilities by sending video, voice and data signals from the optical node back to the headend. These transmitters are available for either analog or digital transport.

Network management

NETWatch Management System. Our NETWatch management system consists of transponders and network management software. The transponders operate in broadband networks to capture measurement data and our software

Technical services

We provide consulting, implementation and maintenance services to our customers worldwide, principally those which purchase CS division products or solutions. We draw upon our expertise in broadcast television, communications networking and compression technology to design, integrate and install complete solutions. We offer a broad range of services and support including program management, budget analysis, technical design and planning, parts inventory management, building and site preparation, integration and equipment installation, end-to-end system testing, comprehensive training and ongoing maintenance. Harmonic also has extensive experience in integrating our products with numerous third-party products and services.

CUSTOMERS

We sell our products to a variety of broadband communications companies. Set forth below is a representative list of our significant end-user and integrator/distributor customers based on net sales during 2004.

Historically, a majority of our sales have been to relatively few customers, and due in part to the consolidation of ownership of cable television and direct broadcast satellite systems, we expect this customer concentration to continue in the foreseeable future. Net sales to our ten largest customers in 2004, 2003 and 2002 accounted for approximately 55%, 65% and 61% of net sales, respectively. In 2004, Comcast accounted for 17% of net sales. In 2003, Comcast accounted for 32% of net sales. In 2002, sales to Charter and Comcast accounted for 18% and 10% of net sales, respectively. If Comcast, which acquired AT&T Broadband in November 2002, and AT&T Broadband had been combined for all of 2002, total net sales to the combined entity would have been 17% of net sales. Although we are attempting to broaden our customer base by penetrating new markets such as the telco and broadcast markets, and expanding internationally, we expect to see continuing industry consolidation and customer concentration due in part to the significant capital costs of constructing broadband networks. For example, Comcast acquired AT&T Broadband in November 2002, thereby creating the largest U.S. cable operator, reaching approximately 22 million subscribers. In the DBS segment, The News Corporation Ltd. acquired an indirect controlling interest in Hughes Electronics, the parent company of DIRECTV in 2003. More recently, this trend has continued with the privatization of Cox Communications, the planned sale of Adelphia out of bankruptcy, and the proposed sale of Cablevision’s VOOM! satellite assets to Echostar. See “Factors That May Affect Our Future Results of Operations — Our Customer Base Is Concentrated And The Loss Of One Or More Of Our Key Customers Would Harm Our Business.”

Sales to customers outside of the U.S. in 2004, 2003 and 2002 represented 42%, 29%, and 29% of net sales, respectively. The increase in our international sales in 2004 from 2003 was due in part to the impact of a major project for a Japanese customer and in part to a general increase in capital spending by international customers. We expect international sales to continue to account for a substantial portion of our net sales for the foreseeable future. International sales are subject to a number of risks, including changes in foreign government regulations and

SALES AND MARKETING

In the U.S. we sell our products principally through our own direct sales force which is organized geographically and by major customer and market to support customer requirements. We sell to international customers through our own direct sales force as well as independent distributors and integrators. Principal sales offices outside of the U.S. are located in the United Kingdom, France, and China. International distributors are generally responsible for importing the products and providing certain installation, technical support and other services to customers in their territory. Our direct sales force and distributors are supported by a highly trained technical staff, which includes application engineers who work closely with operators to develop technical proposals and design systems to optimize system performance and economic benefits to operators. Technical support provides a customized set of services, as required, for ongoing maintenance, support-on-demand and training for our customers and distributors both in our facilities and on-site.

Our marketing organization develops strategies for product lines and market segments, and, in conjunction with our sales force, identifies the evolving technical and application needs of customers so that our product development resources can be most effectively and efficiently deployed to meet anticipated product requirements. Our marketing organization is also responsible for setting price levels, demand forecasting and general support of the sales force, particularly at major accounts. We have many programs in place to heighten industry awareness of Harmonic and our products, including participation in technical conferences, publication of articles in industry journals and exhibitions at trade shows.

MANUFACTURING AND SUPPLIERS

We use third party contract manufacturers extensively to assemble full turnkey products and a substantial majority of subassemblies and modules for our products. Our increasing reliance on subcontractors involves several risks, and we may not be able to obtain an adequate supply of components, subassemblies, modules and turnkey systems on a timely basis. In late 2003, we entered into a three-year agreement with Plexus Services Corp. as our primary contract manufacturer. The transition of our manufacturing requirements from certain current contract manufacturers to Plexus was completed in the summer of 2004. Difficulties in managing relationships with contract manufacturers could impede our ability to meet our customers’ requirements and adversely affect our operating results. See “Factors That May Affect Our Future Results of Operations — We Purchase Several Key Components, Subassemblies And Modules Used in The Manufacture or Integration of Our Products From Sale or Limited Resources, And We Are Increasingly Dependent on Contract Manufacturers.”

Our manufacturing operations consist primarily of final assembly and testing of fiber optic systems for our BAN division. These processes are performed by highly trained personnel employing technologically advanced electronic equipment and proprietary test programs. The manufacturing of our products and subassemblies is a complex process and we cannot be sure that we will not experience production problems or manufacturing delays in the future. Because we utilize our own manufacturing facilities for the final assembly and test of our BAN division fiber optic systems, and because such manufacturing capabilities are not readily available from third parties, any interruption in our own or our contract manufacturers operations could materially and adversely affect our business, operating results, financial position or cash flows.

Many components, subassemblies and modules necessary for the manufacture or integration of our products are obtained from a sole supplier or a limited group of suppliers. For example, we are dependent on LSI Logic for video

INTELLECTUAL PROPERTY

We currently hold 39 issued U.S. patents and 19 issued foreign patents, and have a number of patent applications pending. Although we attempt to protect our intellectual property rights through patents, trademarks, copyrights, licensing arrangements, maintaining certain technology as trade secrets and other measures, we cannot assure you that any patent, trademark, copyright or other intellectual property rights owned by us will not be invalidated, circumvented or challenged, that such intellectual property rights will provide competitive advantages to us or that any of our pending or future patent applications will be issued with the scope of the claims sought by us, if at all. We cannot assure you that others will not develop technologies that are similar or superior to our technology, duplicate our technology or design around the patents that we own. In addition, effective patent, copyright and trade secret protection may be unavailable or limited in certain foreign countries in which we do business or may do business in the future.

We believe that patents and patent applications are not currently significant to our business, and investors therefore should not rely on our patent portfolio to give us a competitive advantage over others in our industry. We believe that the future success of our business will depend on our ability to translate the technological expertise and innovation of our personnel into new and enhanced products. We generally enter into confidentiality or license agreements with our employees, consultants, vendors and customers as needed, and generally limit access to and distribution of our proprietary information. Nevertheless, we cannot assure you that the steps taken by us will prevent misappropriation of our technology. In addition, we have taken in the past, and may take in the future, legal action to enforce our patents and other intellectual property rights, to protect our trade secrets, to determine the validity and scope of the proprietary rights of others, or to defend against claims of infringement or invalidity. Such litigation could result in substantial costs and diversion of resources and could negatively affect our business, operating results, financial position or cash flows.

In order to successfully develop and market certain of our planned products for digital applications, we may be required to enter into technology development or licensing agreements with third parties. Although many companies are often willing to enter into such technology development or licensing agreements, we cannot assure you that such agreements will be negotiated on terms acceptable to us, or at all. The failure to enter into technology development or licensing agreements, when necessary, could limit our ability to develop and market new products and could cause our business to suffer.

Harmonic’s industry is characterized by the existence of a large number of patents and frequent claims and related litigation regarding patent and other intellectual property rights. In particular, leading companies in the telecommunications industry have extensive patent portfolios. From time to time, third parties, including certain of these leading companies, have asserted and may assert exclusive patent, copyright, trademark and other intellectual property rights against us or our customers. There can be no assurance that the terms of any offered license would be acceptable to our customers or that failure to obtain a license or the costs associated with any license would not

BACKLOG

We schedule production of our systems based upon our backlog, open contracts, informal commitments from customers and sales projections. Our backlog consists of firm purchase orders by customers for delivery within the next twelve months as well as deferred revenue which is expected to be recognized within the next twelve months. At December 31, 2004, backlog, including deferred revenue, amounted to $55.0 million, compared to $45.8 million at December 31, 2003. Anticipated orders from customers may fail to materialize and delivery schedules may be deferred or canceled for a number of reasons, including reductions in capital spending by cable, satellite and other operators or changes in specific customer requirements. In addition, due to weather-related seasonal factors and annual capital spending budget cycles at many major end-users, our backlog at December 31, 2004, or any other date, is not necessarily indicative of actual sales for any succeeding period.

COMPETITION

The markets for cable television fiber optics systems and digital video systems are extremely competitive and have been characterized by rapid technological change and declining average selling prices. The principal competitive factors in these markets include product performance, reliability, price, breadth of product offerings, network management capabilities, sales and distribution capabilities, technical support and service, and relationships with network operators. We believe that we compete favorably in each of these categories. Harmonic’s competitors in the fiber optics systems business include corporations such as C-Cor, Motorola and Scientific-Atlanta. In the digital video systems business, we compete broadly with vertically integrated system suppliers including Motorola, Scientific-Atlanta, Tandberg Television and Thomson Multimedia, and in certain product lines with Cisco and a number of smaller companies.

Many of our competitors are substantially larger and have greater financial, technical, marketing and other resources than Harmonic. Many of these large organizations are in a better position to withstand any significant reduction in capital spending by customers in these markets. They often have broader product lines and market focus and will therefore not be as susceptible to downturns in a particular market. In addition, many of our competitors have been in operation longer than we have and therefore have more long-standing and established relationships with domestic and foreign customers. We may not be able to compete successfully in the future and competition may harm our business, operating results, financial position or cash flows.

If any of our competitors’ products or technologies were to become the industry standard, our business could be seriously harmed. In addition, companies that have historically not had a large presence in the broadband communications equipment market have expanded their market presence through mergers and acquisitions. Further, our competitors, particularly competitors of our digital and video broadcasting systems’ business, may bundle their products or incorporate functionality into existing products in a manner that discourages users from purchasing our products or which may require us to lower our selling prices, which could result in lower gross margins.

RESEARCH AND DEVELOPMENT

We have historically devoted a significant amount of our resources to research and development. Research and development expenses in 2004, 2003 and 2002 were $35.6 million, $35.1 million and $40.8 million, respectively.

Our research and development program is primarily focused on developing new products and systems, and adding new features to existing products and systems. Our development strategy is to identify features, products and systems for both software and hardware that are, or expected to be, needed by our customers. Our current research and development efforts in the CS division are focused heavily on video compression systems in MPEG2 and the new compression standards (MPEG4 or AVC and Microsoft VC-1). We also devote resources to products for MPEG over Internet Protocol (IP), VOD and switched broadcast and stream management software. The BAN division research and

Our success in designing, developing, manufacturing and selling new or enhanced products will depend on a variety of factors, including the identification of market demand for new products, product selection, timely implementation of product design and development, product performance, effective manufacturing and assembly processes and sales and marketing. Because of the complexity inherent in such research and development efforts, we cannot assure you that we will successfully develop new products, or that new products developed by us will achieve market acceptance. Our failure to successfully develop and introduce new products could harm our business and operating results.

EMPLOYEES

As of December 31, 2004, we employed a total of 590 people, including 217 in sales, service and marketing, 172 in research and development, 104 in manufacturing operations and 97 in a general and administrative capacity. There are 467 employees in the U.S. and 123 employees in foreign countries who are located in the Middle East, Europe and Asia. We also employ a number of temporary employees and consultants on a contract basis. From January 1, 2001 to December 31, 2003, we reduced our work force by approximately 44% primarily in response to a significant slowing of industry spending and the consequent adverse impact on our operating results. In response to sales growth in 2004, we commenced hiring again, and added 33 people in 2004. None of our employees is represented by a labor union with respect to his or her employment by Harmonic. We have not experienced any work stoppages and we consider our relations with our employees to be good. Our future success will depend, in part, upon our ability to attract and retain qualified personnel. Competition for qualified personnel in the broadband communications industry and in our immediate geographic area remains strong, and we cannot assure you that we will be successful in retaining our key employees or that we will be able to attract skilled personnel in the future.

All of our facilities are leased, including our principal operations and corporate headquarters in Sunnyvale, California. We also have research and development centers in Colorado and New York, several sales offices in the U.S., sales and support centers in the United Kingdom, France, and China, and a research and development center in Israel. Our leases, which expire at various dates through September 2010, are for approximately 400,000 square feet of space. In the U.S., of the 366,000 square feet under lease, approximately 137,000 square feet is in excess of our requirements and we no longer occupy, do not intend to occupy, and have subleased, or plan to sublease. The estimated loss on subleases has been included in the excess facilities charges recorded in 2001 and 2002.

Shareholder Litigation

Between June 28 and August 25, 2000, several actions alleging violations of the federal securities laws by Harmonic and certain of its officers and directors (some of whom are no longer with Harmonic) were filed in or removed to the U.S. District Court for the Northern District of California. The actions subsequently were consolidated.

A consolidated complaint, filed on December 7, 2000, was brought on behalf of a purported class of persons who purchased Harmonic’s publicly traded securities between January 19 and June 26, 2000. The complaint also alleged claims on behalf of a purported subclass of persons who purchased C-Cube securities between January 19 and May 3, 2000. In addition to Harmonic and certain of its officers and directors, the complaint also named C-Cube Microsystems Inc. and several of its officers and directors as defendants. The complaint alleged that, by making false or misleading statements regarding Harmonic’s prospects and customers and its acquisition of C-Cube, certain defendants violated sections 10(b) and 20(a) of the Securities Exchange Act of 1934. The complaint also alleged that certain defendants violated section 14(a) of the Exchange Act and sections 11, 12(a)(2), and 15 of the Securities Act of 1933 by filing a false or misleading registration statement, prospectus, and joint proxy in connection with the C-Cube acquisition.

A derivative action purporting to be on behalf of Harmonic was filed against its then-current directors in the Superior Court for the County of Santa Clara on September 5, 2000. Harmonic also was named as a nominal defendant. The complaint is based on allegations similar to those found in the securities class action and claims that the defendants breached their fiduciary duties by, among other things, causing Harmonic to violate federal securities laws. The derivative action was removed to the U.S. District Court for the Northern District of California on September 20, 2000. All deadlines in this action were stayed pending resolution of the motions to dismiss the securities class action. On July 29, 2003, the Court approved the parties’ stipulation to dismiss this derivative action without prejudice and to toll the applicable limitations period. The limitations period is tolled until fourteen days after (1) defendants provide plaintiff with a copy of the mandate issued by the Ninth Circuit in the securities action or (2) either party provides written notice of termination of the tolling period, whichever is first.

A second derivative action purporting to be on behalf of Harmonic was filed in the Superior Court for the County of Santa Clara on May 15, 2003. It alleges facts similar to those previously alleged in the securities class action and the federal derivative action. The complaint names as defendants former and current Harmonic officers and directors, along with former officers and directors of C-Cube Microsystems, Inc., who were named in the securities class action. The complaint also names Harmonic as a nominal defendant. The complaint alleges claims for abuse of control, gross mismanagement, and waste of corporate assets against the Harmonic defendants, and claims for breach of fiduciary duty, unjust enrichment, and negligent misrepresentation against all defendants. On July 22, 2003, the Court approved the parties’ stipulation to stay the case pending resolution of the appeal in the securities class action. Although the parties initially agreed in principle to a dismissal without prejudice on similar terms as in the federal derivative action, after further discussion, the parties decided that the stay currently in place suffices to protect their respective interests.

Based on its review of the complaints filed in the securities class actions, Harmonic believes that it has meritorious defenses and intends to defend itself vigorously. There can be no assurance, however, that Harmonic will prevail. No estimate can be made of the possible range of loss associated with the resolution of this contingency and accordingly, Harmonic has not recorded a liability. An unfavorable outcome of this litigation could have a material adverse effect on Harmonic’s business, operating results, financial position or cash flows.

Other Litigation

On July 3, 2003, Stanford University and Litton Systems filed a complaint in U.S. District Court for the Central District of California alleging that optical fiber amplifiers incorporated into certain of Harmonic’s products infringe U.S. Patent No. 4,859,016. This patent expired in September 2003. The complaint seeks injunctive relief, royalties and damages. Harmonic has not been served in the case. Harmonic is currently evaluating its position with respect to this patent and has engaged in discussions with the plaintiff regarding potential settlement of the matter. At this time, we are unable to determine whether we will be able to settle this litigation on reasonable terms or at all, nor can we predict the impact of an adverse outcome of this litigation if we elect to defend against it. No estimate can be made of the possible range of loss associated with the resolution of this contingency and accordingly, we have not recorded a liability associated with the outcome of a negotiated settlement or an unfavorable verdict in litigation. An unfavorable outcome of this matter could have a material adverse effect on Harmonic’s business, operating results, financial position or cash flows.

No matters were submitted to a vote of stockholders during the fourth quarter of the year ended December 31, 2004.

PART II

Market information: Harmonic’s Common Stock has been quoted on the Nasdaq National Market under the symbol HLIT since Harmonic’s initial public offering on May 22, 1995. The following table sets forth, for the periods indicated, the high and low sales price per share of the Common Stock as reported on the Nasdaq National Market:

Holders of record: At March 1, 2005 there were 498 stockholders of record of Harmonic’s Common Stock.

Dividends: Harmonic has never declared or paid any dividends on its capital stock. Harmonic currently expects to retain future earnings, if any, for the use in the operation and expansion of its business and does not anticipate paying any cash dividends in the foreseeable future. Harmonic’s line of credit includes covenants prohibiting the payment of dividends.

Securities authorized for issuance under equity compensation plans: The disclosure required by Item 201(d) of Regulation S-K is set forth in the 2005 Proxy Statement under the caption “Equity Plan Information” and is incorporated herein by reference.

Sales of unregistered securities: During the fiscal year ended December 31, 2004, Harmonic did not sell any securities in transactions that were not registered under the Securities Act of 1933. On February 25, 2005, Harmonic purchased all of the issued and outstanding shares of Broadcast Technology Ltd. (BTL), a private U.K. company, for a purchase consideration of approximately £3.0 million in cash and 169,112 shares of Harmonic’s common stock. Harmonic purchased all of the shares of BTL directly from, and paid the consideration thereof directly to, the shareholders of BTL. In connection with such sale of our common stock, Harmonic relied upon the exemption from registration under the Securities Act provided by Regulation S. Harmonic based its reliance upon Regulation S on the fact that the offer and sale of Harmonic’s common stock was made in the U.K., there were no directed selling efforts made by Harmonic in the U.S. with respect to such securities, and Harmonic required the purchasers of its common stock to agree to such restrictions on resale and other matters as required by Regulation S.

Purchase of equity securities by the issuer and affiliated purchasers: During the three months ended December 31, 2004, Harmonic did not, nor did any of its affiliated entities, repurchase any of Harmonic’s equity securities.

The data set forth below are qualified in their entirety by reference to, and should be read in conjunction with, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and the Consolidated Financial Statements and related notes included elsewhere in this Annual Report on Form 10-K.

The 2003 gross profit, loss from operations and net loss included credits of $4.7 million for products sold during the year that had been written down in prior years. Operating expenses included credits of $2.2 million from the sale of our bankruptcy claims in Adelphia Communications resulting in the reversal of previously recorded bad debt provisions, and a litigation settlement charge of $2.7 million related to Power and Telephone Supply.

The 2002 gross profit, loss from operations and net loss included special charges to cost of sales totaling $0.8 million for severance and other costs, and credits of $6.9 million for products sold during the year that had been written down in prior years. Special charges to operating expenses totaled $22.5 million for excess facilities costs, a bad debt provision of $2.7 million for probable losses on receivables from Adelphia Communications, and severance and other costs of $0.9 million.

The 2001 gross profit, loss from operations and net loss included special charges to cost of sales totaling $40.0 million for inventory and fixed asset write-downs and $0.9 million for severance and other costs. Special charges to operating expenses include $30.1 million for excess facilities costs, $2.4 million for fixed asset provisions and $1.6 million for severance and other costs and special charges of $0.6 million to other income and expense.

The 2000 loss from operations and net loss included special charges to operating expenses of approximately $1.42 billion, consisting of $1.38 billion for impairment of goodwill and other intangible assets and $39.8 million for acquired in-process technology. Special charges to cost of sales totaled $10.0 million for excess and obsolete inventories.

Overview

Harmonic designs, manufactures and sells digital video systems and fiber optic systems that enable network operators to provide a range of interactive and advanced digital services that include digital video, VOD, HDTV, high-speed Internet access and telephony. Our digital video systems enable our customers to process video for distribution over cable, satellite, telephone and wireless networks. We also provide fiber optic transmission systems to cable television operators and to certain telephone companies that offer video services to their customers.

In order to further expand our digital systems capability, Harmonic acquired C-Cube Microsystems Inc.’s Divicom business in May 2000, which provided encoding products and systems for digital television. Since the merger, Harmonic has been organized into two operating divisions, Broadband Access Networks, or BAN, for fiber optic systems and Convergent Systems, or CS, for digital headend systems.

Harmonic’s net sales increased 36% in 2004, and decreased 2% in 2003 and 8% in 2002. Although industry capital spending has been generally weak as compared to the pre-merger levels achieved by Harmonic and Divicom in 1999 and early 2000, we believe that the sequential quarterly sales increases in 2003 and the increase in 2004 compared to 2003 reflected an improved industry capital spending environment worldwide which favorably impacted Harmonic. We believe that this improvement in the industry capital spending environment is, in part, a result of the intensifying competition between cable and satellite operators to offer more channels of digital video and new services, such as VOD and HDTV, and in part, the result of the entry of telephone companies into the business of delivering video services to their subscribers. We also believe that the improvement is due to more favorable conditions in industry capital markets and the completion or resolution of certain major business combinations, financial restructurings and regulatory issues.

Our quarterly and annual results may fluctuate significantly due to revenue recognition policies and the timing of the receipt of orders. Revenue from two significant customer orders in the third quarter of 2004 was delayed due to these factors until the fourth quarter of 2004. As a result, we expect revenue in the first quarter of 2005 will be sequentially lower than the revenue in the fourth quarter of 2004.

Historically, a majority of our net sales have been to relatively few customers, and due in part to the consolidation of ownership of cable television and direct broadcast satellite systems, we expect this customer concentration to continue for the foreseeable future. In 2004, sales to Comcast accounted for 17% of net sales. In 2003, sales to Comcast accounted for 32% of net sales. In 2002, sales to Charter Communications and Comcast accounted for 18% and 10% of net sales, respectively. If Comcast, which acquired AT&T Broadband in November 2002, and AT&T Broadband had been combined for all of 2002, total sales to the combined entity would have been 17% of net sales.

In 2004, 2003, and 2002, sales of BAN products accounted for approximately 31%, 38%, and 41% of net sales, respectively, while CS products accounted for approximately 69%, 62%, and 59% of net sales, respectively.

Sales to customers outside of the U.S. in 2004, 2003, and 2002 represented 42%, 29%, and 29% of net sales, respectively. A significant portion of international sales are made to distributors and system integrators, which are generally responsible for importing the products and providing installation and technical support and service to customers within their territory. Sales denominated in foreign currencies were approximately 4% of net sales in 2004 and 2003. We expect international sales to continue to account for a significant portion of our net sales for the foreseeable future.

In 2004, annual growth in net sales of 36%, improved gross margins, and operating expense growth of 13% enabled Harmonic to return to profitability. We reported net income of $1.6 million in 2004, compared to net losses of $29.4 million and $76.9 million in 2003 and 2002, respectively. Our operating results in 2004 included credits of $4.0 million for products sold during the year which had been written down in prior years.

In 2002, certain of our domestic and international customers that had accumulated significant levels of debt announced reorganizations and financial restructurings, including bankruptcy filings. In particular, Adelphia Communications declared bankruptcy in June 2002, and as a result, we recorded only nominal revenue from Adelphia between the first quarter of 2002 and the second quarter of 2003 and established a $2.9 million provision in the second quarter of 2002 for probable losses on receivables and deferred costs of sales determined to no longer be recoverable. Adelphia has accounted for less than 5% of net sales in each of 2002, 2003 and 2004. We believe that capital market concerns about the cable industry and the associated pressures on capital spending contributed to the 31% decrease in sales during the second half of 2002 compared to the first half of 2002. In addition, spending by our domestic satellite customers and European customers was weak in 2002, particularly in the second half of 2002. We believe that this was principally because of pending business consolidations, financial restructurings and regulatory issues. For example, we believe that the regulatory review of the proposed acquisition of DIRECTV by Echostar depressed spending in 2002, particularly in the second half of 2002. Although this proposed combination was not completed, The News Corporation Ltd., subsequently acquired an indirect controlling interest in Hughes Electronics, the parent of DIRECTV, in December 2003.

As a result of uncertain market conditions and lower sales during the second half of 2002, we implemented a series of cost control measures that included workforce reductions totaling approximately 120 employees during the second half of 2002. Harmonic recorded severance charges of $1.5 million during the second half of 2002 related to the work force reductions. This followed a workforce reduction of approximately 30% during 2001 for which we recorded severance and other costs of $2.5 million at the time. These actions reduced headcount from over 1,000 at the end of 2000 to 587 at the end of 2002. We further reduced headcount to 557 in 2003, mainly by attrition, but the improved business environment in 2004 led us to increase headcount to 590 at the end of 2004. If business conditions remain favorable, we expect to continue to add to our headcount during 2005.

In light of our reduced headcount, difficult business conditions, and a weak local commercial real estate market, we reassessed our accrual for the costs of excess facilities and recorded a charge of $22.5 million during the third quarter of 2002. We changed our estimates with regard to the expected timing and amount of sublease income due to the substantial and growing surplus of vacant space in the San Francisco Bay Area. The excess facilities charge recorded during the third quarter of 2002 was for facilities that we no longer occupy, do not intend to occupy, and have subleased, or plan to sublease, and followed charges of $30.1 million recorded for excess facilities in 2001 when the initial accruals were established.

A review performed in the third quarter of 2003 resulted in the excess facilities liability being decreased by $3.3 million due to a revision in the assumptions as to the unoccupied portion of a building. We removed approximately 12,000 square feet of space from the excess facilities portfolio in order to eliminate a third-party offsite storage arrangement. Based on the remaining lease term of 84 months, this removal resulted in a reduction of $3.3 million in the required excess facilities reserve. This revision was offset by a correction of straight-line rent expense of $2.3 million as a result of a lease extension on another building. This lease extension was a condition of leasing three additional buildings at corporate headquarters and resulted in all leases terminating in September 2010. The deferred rent liability was not adjusted for the change in the lease term resulting in an understatement of rent expense and the deferred rent liability at December 31, 2001, 2002 and 2003. Because the effect of the correction on any quarter or year was not material to these results of operations and financial position, the non-cash adjustment was recorded in 2003. Although we have entered into new subleases for approximately 60,000 square feet of space in 2004, in the event we are unable to achieve expected levels of sublease rental income, we will need to revise our estimate of the liability, which could materially impact our financial position, liquidity, cash flows and results of operations.

In the fourth quarter of 2003, Harmonic sold and issued 10,350,000 shares of common stock in a public offering at a price of $7.40 per share. The net proceeds to Harmonic were approximately $71.4 million, which was net of underwriters’ discounts and commissions of approximately $4.2 million and related legal, accounting, printing and other expenses totaling approximately $0.9 million. The net proceeds from the offering are being used for general corporate purposes, including payment of existing liabilities, research and development, the development or acquisition of new products or technologies, equipment acquisitions, strategic acquisitions of businesses, general working capital and operating expenses. The offering was made pursuant to our Registration Statement on Form S-3 (File No. 333-84430) filed with the SEC on March 18, 2002, as amended on April 16, 2002 and as declared effective on April 18, 2002, and the related prospectus supplement filed with the SEC on October 29, 2003. The Form S-3 registration statement used in this public offering remains effective and Harmonic continues to have the ability to issue various types of securities, up to an aggregate of $73 million.

On February 25, 2005, Harmonic purchased all of the issued and outstanding shares of Broadcast Technology Ltd., a private U.K. company, for a purchase consideration of £4.0 million, or approximately $7.6 million. The purchase consideration consists of a payment of £3.0 million in cash and the issuance of 169,112 shares of Harmonic common stock. Broadcast Technology Ltd. develops, manufactures and distributes professional video/ audio receivers and decoders and has approximately 40 employees.

Critical Accounting Policies, Judgments and Estimates

The preparation of financial statements and related disclosures requires Harmonic to make judgments, assumptions and estimates that affect the reported amounts of assets and liabilities, the disclosure of contingencies and the reported amounts of revenue and expenses in the financial statements and accompanying notes. Material differences may result in the amount and timing of revenue and expenses if different judgments or different estimates were made. See Note 1 of Notes to Consolidated Financial Statements for details of Harmonic’s accounting policies. Critical accounting policies, judgments and estimates which we believe have the most significant impact on Harmonic’s financial statements are set forth below:

Revenue Recognition

Harmonic’s principal sources of revenue are from sales of hardware products, software products, solution sales, services and hardware and software maintenance agreements. Harmonic recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred or services have been provided, the sale price is fixed or determinable, collection is reasonably assured, and risk of loss and title have transferred to the customer.

We evaluate our products to assess whether software is more-than-incidental to a product. When we conclude that software is more-than-incidental to a product, we account for the product as a software product. Significant judgment may be required in determining whether a product is a software or hardware product.

Revenue from hardware product sales is recognized in accordance with the provisions of Staff Accounting Bulletin No. 104, “Revenue Recognition.” Subject to other revenue recognition provisions, revenue on product sales is recognized when risk of loss and title has transferred, which is generally upon shipment or delivery, based on the terms of the arrangement. Revenue on shipments to distributors, resellers and systems integrators is generally recognized on delivery or sell-in. Allowances are provided for estimated returns and discounts. Such allowances are adjusted periodically to reflect actual and anticipated experience.

Distributors and systems integrators purchase our products for specific capital equipment projects of the end-user and do not hold inventory. They perform functions that include importation, delivery to the end-customer, installation or integration, and post-sales service and support. Our agreements with these distributors and systems integrators have terms which are generally consistent with the standard terms and conditions for the sale of our equipment to end users and do not provide for product rotation or pricing allowances, as are typically found in agreements with stocking distributors. We have long-term relationships with most of these distributors and systems integrators and substantial experience with similar sales of similar products. We have had extensive experience monitoring product returns from our international distributors and accordingly, we have concluded that the amount of future returns can be reasonably estimated. With respect to these sales, we evaluate the terms of sale and recognize revenue when persuasive evidence of an arrangement exists, delivery has occurred or services have been provided, the sales price is fixed or determinable, collectibility is reasonably assured, and risk of loss and title have transferred.

When arrangements contain multiple elements, Harmonic evaluates all deliverables in the arrangement at the outset of the arrangement based on the guidance in Emerging Issues Task Force (EITF) No. 00-21, “Accounting for Revenue Arrangements with Multiple Deliverables.” If the undelivered elements qualify as separate units of accounting based on the criteria in EITF 00-21, which include that the delivered elements have value to the customer on a stand-alone basis and that objective and reliable evidence of fair value exists for undelivered elements, Harmonic allocates the arrangement fee based on the relative fair value of the elements of the arrangement. If a delivered element does not meet the criteria in EITF 00-21 to be considered a separate unit of accounting, revenue is deferred until the undelivered elements are fulfilled. Accordingly, the determination as to whether appropriate objective and reliable evidence of fair value exists can impact the timing of revenue recognition for an arrangement.

Revenue on solution sales, which principally consist of and include the design, manufacture, test, integration and installation of equipment to the specifications of Harmonic’s customers, including equipment acquired from third parties to be integrated with Harmonic’s products, is generally recognized using the percentage of completion method in accordance with Statement of Position (SOP) 81-1 “Accounting for Performance of Construction/ Production Contracts.” Under the percentage of completion method, revenue recognized reflects the portion of the anticipated contract revenue that has been earned, equal to the ratio of labor costs expended to date to anticipated final labor costs, based on current estimates of labor costs to complete the project. If the estimated costs to complete a project exceed the total contract amount, indicating a loss, the entire anticipated loss is recognized. Deferred revenue includes billings in excess of revenue recognized, net of deferred costs of sales. Our application of percentage-of-completion accounting is subject to our estimates of labor costs to complete each project. In the event that actual results differ from these estimates or we adjust these estimates in future periods, our operating results, financial position or cash flows for a particular period could be adversely affected.

Revenue from hardware and software maintenance agreements is recognized ratably over the term of the maintenance agreement. First year maintenance typically is included in the original arrangement and renewed on an annual basis thereafter. Services revenue is recognized on performance of the services and costs associated with services are

Significant management judgments and estimates must be made in connection with determination of the revenue to be recognized in any accounting period. Because of the concentrated nature of our customer base, different judgments or estimates made for any one large contract or customer could result in material differences in the amount and timing of revenue recognized in any particular period.

Allowances for Doubtful Accounts, Returns and Discounts

We establish allowances for doubtful accounts, returns and discounts based on credit profiles of our customers, current economic trends, contractual terms and conditions and historical payment, return and discount experience, as well as for known or expected events. If there were to be a deterioration of a major customer’s creditworthiness or if actual defaults, returns or discounts were higher than our historical experience, our operating results, financial position and cash flows could be adversely affected. At December 31, 2004, our allowances for doubtful accounts, returns and discounts totaled $5.1 million.

Valuation of Inventories

Harmonic states inventories at the lower of cost or market. We provide inventory allowances based on excess and obsolete inventories determined primarily by future demand forecasts. If there were to be a sudden and significant decrease in demand for our products, or if there were a higher incidence of inventory obsolescence because of rapidly changing technology and customer requirements, we could be required to increase our inventory allowances and our gross margin could be adversely affected. Inventory management is of critical importance in order to balance the need to maintain strategic inventory levels to ensure competitive lead times against the risk of inventory obsolescence because of rapidly changing technology and customer requirements.

Impairment of Goodwill or Long-lived Assets

We perform an evaluation of the carrying value of goodwill on an annual basis and of intangibles and other long-lived assets whenever we become aware of an event or change in circumstances that would indicate potential impairment. We evaluate the recoverability of other intangible assets and long-lived assets on the basis of undiscounted cash flows from each asset group. If impairment is indicated, provisions for impairment are determined based on fair value, principally using discounted cash flows. Changes in industry and market conditions or the strategic realignment of our resources could result in an impairment of identified intangibles, goodwill or long-lived assets. There can be no assurance that future impairment tests will not result in a charge to earnings. At December 31, 2004, our carrying values for goodwill and intangible assets totaled $1.8 million and $4.6 million, respectively.

Restructuring Costs and Accruals for Excess Facilities

For restructuring activities initiated prior to December 31, 2002 we recorded restructuring costs when Harmonic committed to an exit plan and significant changes to the exit plan were not likely. To determine our excess facility accruals we estimate expected sublease rental income on each excess facility. In the event we are unable to achieve expected levels of sublease rental income, we will need to revise our estimate of the liability which could materially impact our operating results, financial position or cash flows. At December 31, 2004, our accurals for excess facilities totaled $29.4 million.

Assessment of the Probability of the Outcome of Current Litigation

Harmonic records accruals for loss contingencies when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. Based on Harmonic’s review of the complaints filed in the securities class action and other pending litigation, Harmonic believes that it either has meritorious defenses with respect to those actions and claims or is unable to predict the impact of an adverse action and, accordingly, no loss contingencies have been accrued. There can be no assurance, however, that we will prevail. An unfavorable outcome

Accounting for Income Taxes

In preparation of our financial statements, we estimate our income taxes for each of the jurisdictions in which we operate. This involves estimating our actual current tax exposures and assessing temporary differences resulting from differing treatment of items, such as reserves and accruals, for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included within our consolidated balance sheet. Based on our judgment that the likelihood that our deferred tax assets will be recovered from future taxable income is not assured, we established a valuation allowance of $104.9 million in 2002 which was increased to $123.6 million in 2003 and decreased to $122.9 million in 2004. At December 31, 2004 we have fully reserved for our net deferred tax assets related to temporary differences and net operating loss and tax credit carryforwards.

Significant management judgment is required in determining our provision for income taxes, our deferred tax assets and liabilities and our future taxable income for purposes of assessing our ability to realize any future benefit from our deferred tax assets. In the event that actual results differ from these estimates or we adjust these estimates in future periods, our operating results and financial position could be materially affected.

Results of Operations

Harmonic’s historical consolidated statements of operations data for each of the three years ended December 31, 2004, 2003, and 2002 as a percentage of net sales, are as follows:

Net Sales

Harmonic’s consolidated, segment and international net sales as compared with the prior year, for each of the three years ended December 31, 2004, 2003, and 2002, are presented in the tables below. Also presented is the related

Net sales increased in the CS division in 2004 compared to 2003, primarily due to stronger spending by international customers and to a lesser degree due to continued spending by domestic customers for the rollout of new services. The CS division sold significantly more encoders in 2004 compared to 2003, offset by a reduction in sales of its Narrowcast Service Gateway (NSG) product for VOD due to the substantial completion of initial deployments by certain domestic cable customers. The increased sales of encoders in 2004 was due in part to the major upgrade by a Japanese customer of their satellite facilities during 2004, and in part to sales of headend equipment to two major international telephone companies for video deployments. Net sales increased in the BAN division in 2004 compared to 2003 as a result of stronger overall spending by U.S. cable operators resulting in increased sales of transmitters and nodes related to continuing network improvements such as node segmentation, and to a lesser degree by an improvement in spending by international cable operators.

Net sales increased in the CS division in 2003 compared to 2002, principally due to stronger spending by domestic cable operators in the second half of 2003 primarily for the roll-out of new services, such as VOD. The decrease in the BAN division net sales in 2003 compared to 2002 was due to reduced capital spending by select cable operators, in particular Charter Communications and Adelphia Communications, during the first half of 2003. We believe this reduced spending was caused by a tightening of the financial markets, and capital markets concerns about the cable industry in the aftermath of the Adelphia bankruptcy filing.

Net sales in the U.S. increased in 2004 compared to 2003 primarily due to stronger overall spending during 2004 by domestic customers from the roll-out of new services, such as VOD and HD television programming, as well as from increased sales of transmitters and nodes for major network upgrades related to continuing network improvements, such as node segmentation. The increased international sales in 2004 was due in part to the impact from a major

Net sales in the U.S. decreased in 2003 compared to 2002 primarily due to lower BAN division sales, partially offset by higher CS division sales. The BAN division sales decrease in 2003 was due to reduced capital spending by select cable operators, in particular Charter Communications and Adelphia Communications, during the first half of 2003. The higher CS division sales in 2003 was due to stronger spending by domestic cable operators primarily for the roll-out of new services, such as VOD. The international sales decrease in 2003 compared to 2002 reflected the continued depressed market conditions, which impacted both divisions.

Gross Profit

Harmonic’s gross profit and gross profit as a percentage of consolidated net sales, for each of the three years ended December 31, 2004, 2003, and 2002 are presented in the table below. Also presented is the related dollar and percentage increase in gross profit as compared with the prior year, for each of the two years ended December 31, 2004 and 2003.

The increase in gross profit in 2004 compared to 2003 was primarily due to higher sales, lower third party manufacturing costs, improvements in factory efficiencies, and a higher proportion of CS division sales, which historically carry a more favorable product margin. These factors, which contributed to higher gross margins in 2004 compared to 2003, were partially offset by a reduction in the benefit related to the sale of products for which the cost basis had been written down in prior years. This benefit was $4.0 million in 2004, as compared to a benefit of $4.7 million in 2003. We do not expect any substantial benefit in future periods from the sale of products for which the cost basis was written down in prior periods. There was no change in the amortization of intangibles of $6.2 million in 2004 compared to 2003, however, amortization of intangibles in 2005 is expected to decrease by approximately $4.1 million.

The increase in gross profit in 2003 compared to 2002 was primarily attributable to a change in the product mix and improvements in factory efficiencies. Also contributing to the higher gross profit in 2003 were cost control measures, including the full year effect of reductions in headcount in the factory and technical service and support organizations, associated with work force reductions during the second half of 2002. These factors, which contributed to higher gross margins in 2003 compared to 2002, were partially offset by lower average selling prices and a reduced benefit of $4.7 million in 2003 compared to $6.9 million in 2002, related to products sold for which the costs basis had been written down in prior years.

Research and Development

Harmonic’s research and development expense and the expense as a percentage of consolidated net sales for each of the three years ended December 31, 2004, 2003, and 2002 are presented in the table below. Also presented is the

The increase in research and development expense in 2004 compared to 2003 was as a result of higher compensation expenses of $2.6 million, resulting from increased headcount and higher compensation costs, and increased outside services for the development and qualification of FTTP products. Partially offsetting these increases was lower depreciation of $0.9 million, lower prototype material costs of $0.7 million and lower facilities and allocation expenses of $1.2 million.

The decrease in research and development expenses in 2003 compared to 2002 was primarily due to the full year effect of the reduction in headcount associated with the workforce reductions in 2002 and ongoing cost control measures. The major expenditures affected were payroll costs and depreciation, although most expenses within research and development have been reduced in the last two years.

Selling, General and Administrative

Harmonic’s selling, general and administrative expense and the expense as a percentage of consolidated net sales, for each of the three years ended December 31, 2004, 2003, and 2002 are presented in the table below. Also presented is the related dollar and percentage increase (decrease) in selling, general and administrative as compared with the prior year, for each of the two years ended December 31, 2004 and 2003.

The increase in selling, general and administrative expenses in 2004 compared to 2003 was primarily due to increases in compensation and incentive related expenses of $6.7 million, increased selling expenses of $0.8 million, increases in corporate governance costs of $2.0 million and increased facilities and allocation expenses of $2.0 million, partially offset by lower depreciation expense of $0.9 million and lower legal expenses due to a charge of $2.7 million in 2003 related to the settlement of litigation. In addition, in 2003, credits to bad debt expenses totaling $4.3 million were recorded, including $2.2 million due to the sale of Adelphia bankruptcy claims.

The decrease in selling, general and administrative expense in 2003 compared to 2002 was due to lower bad debt expenses caused by the sale of our bankruptcy claims in Adelphia Communications resulting in the reversal of previously recorded bad debt provisions of approximately $2.2 million and the full year effect of work force reductions in 2002. In addition, selling, general and administrative expense in 2002 included excess facilities charges of $22.5 million.

Harmonic’s amortization of intangibles expense charged to operating expenses, and the expense as a percentage of consolidated net sales, for each of the three years ended December 31, 2004, 2003, and 2002 are presented in the table below. Also presented is the related dollar and percentage increase (decrease) in amortization of intangibles as compared with the prior year, for each of the two years ended December 31, 2004 and 2003.

There was no change in amortization of intangibles charged to operating expenses in 2004 compared to 2003. Harmonic expects to record a total of approximately $2.6 million in amortization of existing intangibles in operating expenses in 2005.

The decrease in 2003 compared to 2002 was due principally to the intangibles arising from the Cogent acquisition becoming fully amortized.

Interest Income, Net

Harmonic’s interest income, net, and interest income, net as a percentage of consolidated net sales, for each of the three years ended December 31, 2004, 2003, and 2002 are presented in the table below. Also presented is the related dollar and percentage increase (decrease) in interest income, net as compared with the prior year, for each of the two years ended December 31, 2004 and 2003.

The increase in 2004 compared to 2003 was due primarily to larger cash and short-term investment balances during the respective periods of 2004 as compared to 2003 principally due to the investment of net proceeds of $71.4 million from the public offering of common stock in the fourth quarter of 2003.

The decrease in 2003 compared to 2002 was due primarily to lower cash and short-term investment balances and lower interest rates during the respective periods of 2003 as compared to 2002.

Other Income (Expense), Net

Harmonic’s other income (expense), net, as a percentage of consolidated net sales, for each of the three years ended December 31, 2004, 2003, and 2002 are presented in the table below. Also presented is the related dollar and

The decrease in 2004 compared to 2003 was primarily due to the effect from losses on foreign exchange of $0.6 million, compared to a gain from foreign exchange of $1.1 million in 2003.

The increase in 2003 compared to 2002 was due primarily to foreign exchange gains of $1.1 million in 2003 compared to zero in 2002 as a result of a weaker dollar.

Income Taxes

Harmonic’s provision for income taxes, and provision for income taxes as a percentage of consolidated net sales, for each of the three years ended December 31, 2004, 2003, and 2002 are presented in the table below. Also presented is the related dollar and percentage increase (decrease) in provision for income taxes as compared with the prior year, for each of the two years ended December 31, 2004 and 2003.

Our effective tax rate was 27.2% in 2004, 1.0% in 2003 and 0.7% in 2002. Harmonic recorded a provision for income taxes of $0.6 million in 2004 principally due to foreign income taxes. Harmonic recorded a provision for income taxes of $0.3 million in 2003 principally due to foreign income taxes despite a loss before income taxes of $29.1 million. In 2002, Harmonic recorded a provision for income taxes of $0.5 million principally due to foreign income taxes despite a loss before income taxes of $76.4 million. The valuation allowance was increased from $104.9 million in 2002 to $123.6 million in 2003 and decreased to $122.9 million in 2004. The valuation allowance is for the full amount of the net deferred tax asset, because realization of any future benefit from deductible temporary differences, net operating losses and tax credit carry forwards was uncertain at December 31, 2004 and December 31, 2003.

Segments

Harmonic’s management uses income from segment operations as its measure of segment profitability. Income from segment operations excludes intangible amortization expense, corporate expenses, including excess facilities charges, and interest and other income, net. See Note 13 of Notes to Consolidated Financial Statements.

Fluctuations in net sales by operating segment are discussed more extensively in the section above entitled Net Sales.

Harmonic’s income (loss) from segment operations and the income (loss) as a percentage of consolidated net sales, for each of the three years ended December 31, 2004, 2003, and 2002 are presented in the table below. Also

The improved CS segment results in 2004 compared to 2003 were due to a 51% increase in sales, lower third party manufacturing costs, and a more favorable margin on the mix of products sold, slightly offset by an increase in operating expenses as compared to 2003. The 2004 increases in operating expenses were as a result of higher selling expenses and slightly higher research and development expenses as compared to 2003. CS segment results included credits of $0.1 million in 2004 related to products sold in 2004 for which the cost basis had been written down in prior years.

The improved CS segment results in 2003 compared to 2002 were due to a 3% increase in sales, higher gross margins from changes in product mix and lower material costs, and lower operating expenses, resulting primarily from lower headcount. CS segment results included credits of $0.5 million in 2003 related to products sold in 2003 for which the cost basis had been written down in prior years.

The improved BAN segment results in 2004 compared to 2003 were due to an 11% increase in sales and a more favorable margin on the mix of products sold during 2004. BAN segment results included credits of $3.9 million in 2004 related to products sold in 2004 for which the cost basis had been written down in prior years.

The improved BAN segment results in 2003 compared to 2002 were due to higher gross margins from improved product mix, improved factory absorption, and lower operating expenses in all areas, resulting primarily from lower headcount. In addition, BAN segment results included credits of $4.2 million in 2003 related to products sold in 2003 for which the cost basis had been written down in prior years.

Liquidity and Capital Resources

As of December 31, 2004, cash, cash equivalents and short-term investments totaled $100.6 million, compared to $112.6 million as of December 31, 2003. Cash used in operations was $9.0 million in 2004 compared to $5.6 million in 2003. The increased use of cash in operations in 2004 was primarily due to increased accounts receivable and inventory, and reduced non-cash charges for depreciation and amortization, which was substantially offset by a change to net income in 2004 from a net loss in 2003. The higher accounts receivable was due to the increase in sales in the fourth quarter to $85.6 million in 2004 compared to $56.3 million in the same period of 2003.

Additions to property, plant and equipment were $6.3 million during 2004 compared to $3.4 million in 2003. The increases in 2004 and 2003 were due primarily to the acquisition of test equipment. Harmonic currently expects capital expenditures to be approximately $8 million during 2005.

On November 3, 2003, Harmonic completed a public offering of 9.0 million shares of its common stock at a price of $7.40 per share. The net proceeds were approximately $62.0 million, which is net of underwriters’ fees of $3.7 million, and related legal, accounting, printing and other expenses totaling approximately $0.9 million. In connection with this offering, the underwriters exercised their option to purchase 1.35 million additional shares of common stock at $7.40 per share on November 12, 2003 to cover over-allotments which resulted in additional net proceeds of approximately $9.4 million. The net proceeds from the offering are being used for general corporate purposes, including payment of existing liabilities, research and development, the development or acquisition of new products or technologies, equipment acquisitions, strategic acquisitions of businesses, general working capital and operating expenses.

Under the terms of the merger agreement with C-Cube, Harmonic is generally liable for C-Cube’s pre-merger tax liabilities. As of December 31, 2004, approximately $15.8 million of pre-merger tax liabilities remained outstanding and are included in accrued liabilities. Harmonic expects to negotiate final settlement and make payment of these obligations to a variety of taxing authorities or to LSI Logic during 2005, including a $5.8 million payment Harmonic made in February 2005 to settle the tax obligation in one country. To the extent that these obligations are finally settled for less than the amount provided, Harmonic is required, under the terms of the merger agreement, to refund the difference to LSI Logic. Accordingly, we expect a significant reduction in cash, cash equivalents and short-term investments during 2005 from these payments. In the event these liabilities are more than $15.8 million, LSI is obligated to indemnify Harmonic for the additional amount.

Harmonic has a bank line of credit facility with Silicon Valley Bank, which provides for borrowings of up to approximately $14.0 million, including $4.0 million for equipment under a secured term loan. This facility, which was amended and restated in December 2004, expires in December 2005 and contains financial and other covenants including the requirement for Harmonic to maintain unrestricted cash, cash equivalents and short-term investments, net of credit extensions, of not less than $50.0 million. If Harmonic is unable to maintain this cash, cash equivalents and short-term investments balance or satisfy the additional affirmative covenant requirements, Harmonic would be in noncompliance with the facility. In the event of noncompliance by Harmonic with the covenants under the facility, Silicon Valley Bank would be entitled to exercise its remedies under the facility which include declaring all obligations immediately due and payable, and disposing of the collateral if obligations were not repaid. At December 31, 2004, Harmonic was in compliance with the covenants under this line of credit facility. An amendment to the line of credit facility entered into during December 2004 resulted in Harmonic paying a fee of approximately $25,000 and requires payment of approximately $37,000 of additional fees if Harmonic does not maintain an unrestricted deposit of $20.0 million with Silicon Valley Bank. Future borrowings pursuant to the line bear interest at the bank’s prime rate (5.25% as of December 31, 2004) or prime plus 0.5% for equipment borrowings. Borrowings are payable monthly and are collateralized by all of Harmonic’s assets. As of December 31, 2004, $2.3 million was outstanding under the equipment term loan portion of this facility and $1.9 million was borrowed during 2004. The term loan is payable monthly, including principal and interest at 5.75% per annum on outstanding borrowings as of December 31, 2004 and matures at various dates through December 2007. Other than standby letters of credit and guarantees, there were no other outstanding borrowings or commitments under the line of credit facility as of December 31, 2004.

Future payments under contractual obligations, and other commercial commitments, as of December 31, 2004, were as follows (in thousands):

In addition, from time to time, we review potential acquisitions that would complement our existing product offerings, enhance our technical capabilities or expand our marketing and sales presence. Any future transaction of this nature could require potentially significant amounts of capital or could require us to issue our stock and dilute existing stockholders. If adequate funds are not available, or are not available on acceptable terms, we may not be able to take advantage of market opportunities, to develop new products or to otherwise respond to competitive pressures.

Our ability to raise funds may be adversely affected by a number of factors relating to Harmonic, as well as factors beyond our control, including increased market uncertainty surrounding the ongoing U.S. war on terrorism, as well

New Accounting Pronouncements

In November 2004, the Financial Accounting Standards Board, or FASB, issued SFAS No. 151, Inventory Costs, to amend the guidance in Chapter 4, Inventory Pricing, of FASB Accounting Research Bulletin No. 43, Restatement and Revision of Accounting Research Bulletins. SFAS 151 clarifies the accounting for abnormal amounts of idle facility expense, freight, handling costs, and wasted material (spoilage) and requires these costs be treated as current period charges. Additionally, SFAS 151 requires that allocation of fixed production overhead to the costs of conversion be based on the normal capacity of the production facilities. The provisions of SFAS 151 are effective for inventory costs incurred during fiscal years beginning after June 15, 2005. We are currently evaluating the impact of SFAS 151 on our financial position, results of operations and liquidity.

In December 2004, the FASB issued SFAS No. 153, Exchanges of Nonmonetary Assets an amendment of APB Opinion No. 29. SFAS 153 amends the guidance in APB Opinion No. 29, Accounting for Nonmonetary Transactions, which is based on the principle that exchanges of nonmonetary assets should be measured based on the fair value of the assets exchanged, with certain exceptions. SFAS 153 amends APB Opinion 29 to eliminate the exception for nonmonetary exchanges of similar productive assets and replaces it with a general exception for exchanges of nonmonetary assets that do not have commercial substance. A nonmonetary exchange has commercial substance if the future cash flows of the entity are expected to change significantly as a result of the exchange. The provisions of SFAS 153 are effective for nonmonetary asset exchanges occurring in fiscal periods beginning after June 15, 2005. We do not currently believe that SFAS 153 will have a significant impact on our financial condition and results of operations.

In December 2004, the FASB issued SFAS No. 123 (revised 2004), Share-Based Payment. SFAS 123R is a revision of FASB SFAS 123, Accounting for Stock-Based Compensation and supersedes APB Opinion No. 25, Accounting for Stock Issued to Employees, and its related implementation guidance. Under SFAS 123(R), we will be required to measure the cost of employee services received in exchange for stock based on the grant-date fair value (with limited exceptions). That cost will be recognized over the period during which an employee is required to provide service in exchange for the award (usually the vesting period). The fair value will be estimated using an option-pricing model. SFAS 123(R) is effective as of the beginning of the first interim or annual reporting period that begins after June 15, 2005. We are currently in the process of evaluating the impact of SFAS 123(R) on our financial statements, including different option-pricing models and which transition method to select.

In March 2004, the FASB issued EITF 03-1, “The Meaning of Other-Than Temporary Impairment and Its Application to Certain Investments,” which provided guidance for assessing impairment losses on investments. Additionally, EITF 03-1 includes new disclosure requirements for investments that are deemed to be temporarily impaired. In September 2004, the FASB delayed the accounting provisions of EITF 03-1; however the disclosure requirements remain effective for annual periods ending after June 15, 2004. We will evaluate the impact of EITF 03-1 once final guidance is issued.

In December 2004, FASB Staff Position No. FAS 109-2, “Accounting and Disclosure Guidance for the Foreign Earnings Repatriation Provision within the American Jobs Creation Act of 2004” (FSP FAS 109-2) was issued, providing guidance under SFAS 109, “Accounting for Income Taxes” for recording the potential impact of the repatriation provisions of the American Jobs Creation Act of 2004, enacted on October 22, 2004. FSP FAS 109-2 allows time beyond the financial reporting period of enactment to evaluate the effects of the Jobs Act before applying the requirements of FSP FAS 109-2. We are currently in the process of evaluating the potential effects of the Jobs Act and have not adjusted our tax expense or deferred tax liability to reflect the requirements of FSP FAS 109-2.

Factors That May Affect Future Results of Operations

We Depend On Cable And Satellite Industry Capital Spending For A Substantial Portion Of Our Revenue And Any Decrease Or Delay In Capital Spending In These Industries Would Negatively Impact Our Resources, Operating Results And Financial Condition And Cash Flows.

These capital spending patterns are dependent on a variety of factors, including:

In the past, specific factors contributing to reduced capital spending have included:

The financial difficulties of certain of our customers and changes in our customers’ deployment plans adversely affected our business throughout 2002 and in the first half of 2003. Two of our major domestic customers, Adelphia Communications and Winfirst, declared bankruptcy during the first half of 2002, while NTL, a major international customer, emerged from bankruptcy in 2003. Furthermore, we believe that our net sales to satellite customers were adversely affected by the uncertainty related to the prolonged regulatory review of the proposed acquisition of DIRECTV by EchoStar in 2002, which was ultimately rejected by regulators. These events, coupled with uncertain and volatile capital markets, also pressured the market values of domestic cable operators and restricted their access to capital. This reduced access to funding for new and existing customers caused delays in the timing and scale of deployments of our equipment and also resulted in the postponement or cancellation of certain projects by our customers. Several customers also canceled new projects or delayed new orders to allow them to reduce inventory levels that were in excess of their deployment requirements. We believe that these factors contributed to decreased net sales in both our CS division and our BAN division during the second half of 2002 and the first half of 2003 compared to the first half of 2002.

We believe that the financial condition of many of our customers has stabilized or improved, and our net sales increased in 2004 compared to 2003. However, another economic downturn or other factors could cause additional financial difficulties among our customers, and customers whose financial condition has stabilized may not purchase new equipment at levels we have seen in the past. Continued financial difficulties among our customers would adversely affect our operating results and financial condition. In addition, industry consolidation has, in the past and

Major U.S. cable operators have indicated that the substantial completion of major network upgrades, which involved significant labor and construction costs, will lead to lower capital expenditures in the future. If our product portfolio and product development plans do not position us well to capture an increased portion of the capital spending of US cable operators, our revenue may decline and our operating results would be adversely affected.

Our Customer Base Is Concentrated And The Loss Of One Or More Of Our Key Customers Would Harm Our Business.

Historically, a majority of our sales have been to relatively few customers, and due in part to the consolidation of ownership of cable television and direct broadcast satellite systems, we expect this customer concentration to continue in the foreseeable future. Sales to our ten largest customers in 2004, 2003, and 2002 accounted for approximately 55%, 65% and 61% of net sales, respectively. Although we are attempting to broaden our customer base by penetrating new markets such as the telecommunications and broadcast markets and expand internationally, we expect to see continuing industry consolidation and customer concentration due in part to the significant capital costs of constructing broadband networks. For example, Comcast acquired AT&T Broadband in November 2002, thereby creating the largest U.S. cable operator, reaching approximately 22 million subscribers. In the DBS segment, The News Corporation Ltd. acquired an indirect controlling interest in Hughes Electronics, the parent company of DIRECTV in 2003. In addition, the sale or financial restructuring of companies such as Adelphia Communications and several European operators may lead to further industry consolidation. In 2004 and 2003, sales to Comcast accounted for 17% and 32%, respectively, of net sales. In 2002, sales to Charter Communications and Comcast accounted for 18% and 10% of net sales. If Comcast and AT&T Broadband had been combined for all of 2002, total revenues for the combined entity would have been 17% of net sales. The loss of Comcast or any other significant customer or any reduction in orders by Comcast or any significant customer, or our failure to qualify our products with a significant customer could adversely affect our business, operating results and liquidity. In this regard, sales to Comcast declined in 2004 compared to 2003, both in absolute dollars and as a percentage of revenues. The loss of, or any reduction in orders from, a significant customer would harm our business.

Our Operating Results Are Likely To Fluctuate Significantly And May Fail To Meet Or Exceed The Expectations Of Securities Analysts Or Investors, Causing Our Stock Price To Decline.

Our operating results have fluctuated in the past and are likely to continue to fluctuate in the future, on an annual and a quarterly basis, as a result of several factors, many of which are outside of our control. Some of the factors that may cause these fluctuations include:

For example, the timing of deployment of our equipment can be subject to a number of other risks, including the availability of skilled engineering and technical personnel, the availability of other equipment such as compatible set top boxes, and our customers’ need for local franchise and licensing approvals.

In addition, we often recognize a substantial portion of our revenues in the last month of the quarter. We establish our expenditure levels for product development and other operating expenses based on projected sales levels, and expenses are relatively fixed in the short term. Accordingly, variations in timing of sales can cause significant fluctuations in operating results. As a result of all these factors, our operating results in one or more future periods may fail to meet or exceed the expectations of securities analysts or investors. In that event, the trading price of our common stock would likely decline. In this regard, due to lower than expected sales during the third quarter of 2002, the first quarter of 2003, and the third quarter of 2004, we failed to meet our internal expectations, as well as the expectations of securities analysts and investors, and the price of our common stock declined, in some cases significantly.

Our Future Growth Depends on Market Acceptance of Several Emerging Broadband Services, on the Adoption of New Broadband Technologies and on Several Other Broadband Industry Trends.

Future demand for our products will depend significantly on the growing market acceptance of several emerging broadband services, including digital video; VOD; HD television; very high-speed data services and voice-over-IP (VoIP) telephony.

The effective delivery of these services will depend, in part, on a variety of new network architectures, such as:

If adoption of these emerging services and/or technologies is not as widespread or as rapid as we expect, or if we are unable to develop new products based on these technologies on a timely basis, our net sales growth will be materially and adversely affected.

If, for instance, operators do not pursue the “triple play” as aggressively as we expect, our net sales growth would be materially and adversely affected. Similar, if our expectations regarding these and other trends are not met, our net sales may be materially and adversely affected.

We Need To Develop And Introduce New And Enhanced Products In A Timely Manner To Remain Competitive.

Broadband communications markets are characterized by continuing technological advancement, changes in customer requirements and evolving industry standards. To compete successfully, we must design, develop, manufacture and sell new or enhanced products that provide increasingly higher levels of performance and reliability. However, we may not be able to successfully develop or introduce these products if our products:

Also, to successfully develop and market certain of our planned products for digital applications, we may be required to enter into technology development or licensing agreements with third parties. We cannot assure you that we will be able to enter into any necessary technology development or licensing agreement on terms acceptable to us, or at all. The failure to enter into technology development or licensing agreements when necessary could limit our ability to develop and market new products and, accordingly, could materially and adversely affect our business and operating results.

Our CS division is currently developing and marketing products based on new video compression standards. Encoding products based on the current MPEG-2 compression standards have represented a significant portion of the Company’s sales since the acquisition of DiviCom in 2000. New standards, such as MPEG-4/ H.264 and Microsoft’s Windows Media 9 broadcast profile (VC-1), are being adopted which are expected to provide significantly greater compression efficiency, thereby making more bandwidth available to operators. Harmonic is developing products based on these new standards in order to remain competitive and is devoting considerable resources to this effort. There can be no assurance that these efforts will be successful in the near future, or at all.

Our BAN division is currently marketing products for FTTP networks which telcos have begun to build. Although we believe that a number of our existing products can be deployed successfully in these networks, we will need to devote considerable resources to obtaining orders, qualifying our products and hiring knowledgeable personnel, and we may make significant financial commitments. There can be no assurance that these efforts will be successful in the near future, or at all.

The sales cycles of many of our products, particularly our newer products and products sold internationally, are typically unpredictable and usually involve:

For these and other reasons, our sales cycles generally last three to six months, but can last up to 12 months. If orders forecasted for a specific customer for a particular quarter do not occur in that quarter, our operating results for that quarter could be substantially lower than anticipated. In this regard, our sales cycles with our current and potential telco customers are particularly unpredictable. Additionally, orders may include multiple elements, the timing of delivery of which may impact the timing of revenue recognition. Quarterly and annual results may fluctuate significantly due to revenue recognition policies and the timing of the receipt of orders. For example, revenue from two significant customer orders in the third quarter of 2004 was delayed due to these factors until the fourth quarter of 2004.

In addition, a significant portion of our revenue is derived from solution sales that principally consist of and include the system design, manufacture, test, installation and integration of equipment to the specifications of Harmonic’s customers, including equipment acquired from third parties to be integrated with Harmonic’s products. Revenue forecasts for solution contracts are based on the estimated timing of the system design, installation and integration of projects. Because the solution contracts generally span several quarters and revenue recognition is based on progress under the contract, the timing of revenue is difficult to predict and could result in lower than expected revenue in any particular quarter.

We Depend On Our International Sales And Are Subject To The Risks Associated With International Operations, Which May Negatively Affect Our Operating Results.

Sales to customers outside of the U.S. in 2004, 2003 and 2002 represented 42%, 29% and 29% of net sales, respectively, and we expect that international sales will continue to represent a meaningful portion of our net sales for the foreseeable future. Furthermore, a substantial portion of our contract manufacturing occurs overseas. Our international operations, the international operations of our contract manufacturers, and our efforts to increase sales in international markets, are subject to a number of risks, including:

During 2004, a significant percentage of our international revenues were derived from a major upgrade by a Japanese customer of its satellite facilities. That upgrade has now been completed, and we expect sales to this customer to decline in 2005, which could adversely affect our sales to international customers.

While our international sales and operating expenses have typically been denominated in U.S. dollars, fluctuations in currency exchange rates could cause our products to become relatively more expensive to customers in a particular country, leading to a reduction in sales or profitability in that country.

Following implementation of the Euro in January 2002, a higher portion of our European business is denominated in Euros, which may subject us to increased foreign currency risk. Gains and losses on the conversion to U.S. dollars of accounts receivable, accounts payable and other monetary assets and liabilities arising from international operations may contribute to fluctuations in operating results. Furthermore, payment cycles for international customers are typically longer than those for customers in the U.S. Unpredictable sales cycles could cause us to fail to meet or exceed the expectations of security analysts and investors for any given period. In addition, foreign markets may not develop in the future. Any or all of these factors could adversely impact our business and results of operations.

Pending Business Combinations And Other Financial And Regulatory Issues Among Our Customers Could Adversely Affect Our Business.

The telecommunications industry has been particularly impacted by the recent economic recession, adverse conditions in capital markets and financial difficulties in both the service and equipment sectors, including bankruptcies. Many of our domestic and international customers accumulated significant levels of debt and announced reorganizations and financial restructurings during the past three years, including bankruptcy filings. In particular, Adelphia Communications, a major domestic cable operator, declared bankruptcy in June 2002. The stock prices of other domestic cable companies came under pressure following the Adelphia bankruptcy due to concerns about debt levels and capital expenditure requirements for new and expanded services, thereby making the raising of capital more difficult and expensive. New operators, such as RCN and WinFirst, also had difficulty in accessing capital markets. Both subsequently filed for bankruptcy. In Europe, rapid consolidation of the cable industry through acquisition also led to significant levels of debt at the major MSOs, and companies such as NTL and UPC went through bankruptcy proceedings. European digital broadcasters, such as ITV Digital, Kirsch and Quiero, also filed for protection from creditors.

While the capital market concerns about the domestic cable industry have eased, market conditions remain difficult and capital spending plans are generally constrained. It is likely that further industry restructuring will take place via mergers or spin-offs, such as the Comcast/ AT&T Broadband transaction in 2002 and the acquisition by The News Corporation Ltd. in December 2003 of an indirect controlling interest in Hughes Electronics, the parent company of DIRECTV. This transaction followed regulatory opposition to the proposed acquisition of DIRECTV by EchoStar. We believe that uncertainty during 2002 regarding the proposed DIRECTV and EchoStar merger adversely affected capital spending by both of these parties as well as other customers. More recently, restructuring of the industry has continued with the privatization of Cox Communications, the planned sale of Adelphia Communications out of bankruptcy, and the proposed sale of Cablevision’s VOOM! satellite assets to Echostar. In addition, further business combinations may occur in our industry, and these further combinations could adversely affect our business. Regulatory issues, financial concerns and business combinations among our customers are likely to significantly affect the industry, its capital spending plans, and our levels of business for the foreseeable future.

Changes in Telecommunications Regulations Could Harm Our Prospects And Future Sales.

Changes in telecommunications regulations in the U.S. and other countries could affect the sales of our products. In particular, regulations dealing with access by competitors to the networks of incumbent operators could slow or stop additional construction or expansion by these operators. Increased regulation of our customers’ pricing or service offerings could limit their investments and consequently the sales of our products. Changes in regulations could have a material adverse effect on our business, operating results, and financial condition.

Our future success will depend, to a significant extent, on the ability of our management to operate effectively, both individually and as a group. We must successfully manage transition and replacement issues that may result from the departure or retirement of members of our senior management. We are dependent on our ability to retain and motivate high caliber personnel, in addition to attracting new personnel. Competition for qualified management, technical and other personnel can be intense, and we may not be successful in attracting and retaining such personnel. Competitors and others have in the past and may in the future attempt to recruit our employees. While our employees are required to sign standard agreements concerning confidentiality and ownership of inventions, we generally do not have employment contracts or non-competition agreements with any of our personnel. The loss of the services of any of our key personnel, the inability to attract or retain qualified personnel in the future or delays in hiring required personnel, particularly senior management and engineers and other technical personnel, could negatively affect our business.

Recent And Proposed Regulations Related To Equity Compensation Could Adversely Affect Earnings, Affect Our Ability To Raise Capital And Affect Our Ability To Attract And Retain Key Personnel.

Since our inception, we have used stock options as a fundamental component of our employee compensation packages. We believe that our stock option plans are an essential tool to link the long-term interests of stockholders and employees, especially executive management, and serve to motivate management to make decisions that will, in the long run, give the best returns to stockholders. The Financial Accounting Standards Board (FASB) has announced changes to U.S. GAAP, effective for fiscal periods beginning after June 15, 2005, that will require us to record a charge to earnings for employee stock option grants and employee stock purchase plan rights. This regulation will negatively impact our earnings and may affect our ability to raise capital on acceptable terms. In addition, new regulations implemented by The Nasdaq National Market requiring stockholder approval for all stock option plans could make it more difficult for us to grant options to employees in the future. To the extent that new regulations make it more difficult or expensive to grant options to employees, we may incur increased compensation costs, change our equity compensation strategy or find it difficult to attract, retain and motivate employees, each of which could materially and adversely affect our business.

We Are Exposed To Additional Costs And Risks Associated With Complying With Increasing And New Regulation Of Corporate Governance And Disclosure Standards.

We are spending an increased amount of management time and external resources to comply with changing laws, regulations and standards relating to corporate governance and public disclosure, including the Sarbanes-Oxley Act of 2002, new SEC regulations and Nasdaq Stock Market rules. Particularly, Section 404 of the Sarbanes-Oxley Act requires management’s annual review and evaluation of our internal controls over financial reporting, and attestation of the effectiveness of our internal controls over financial reporting by management and the Company’s independent registered public accounting firm in connection with the filing of this annual report on Form 10-K for the fiscal year ended December 31, 2004, and with each subsequently filed annual report on Form 10-K. We have documented and tested our internal control systems and procedures and have made improvements in order for us to comply with the requirements of Section 404. This process required us to hire additional personnel and outside advisory services and has resulted in significant additional accounting and legal expenses. While our assessment of our internal controls over financial reporting resulted in our conclusion that as of December 31, 2004, our internal control over financial reporting was effective, we cannot predict the outcome of our testing in future periods. If we conclude in future periods that our internal controls over financial reporting are not effective or if our independent registered public accountants are unable to provide an unqualified opinion as of future year-ends, investors may lose confidence in our financial statements, and the price of our stock may suffer.

We have generated substantial operating losses since we began operations in June 1988. Although we generated a small net profit in 2004 after several years of losses, future profitability is highly uncertain, and we may never achieve sustained profitable operations. We have been engaged in the design, manufacture and sale of a variety of broadband products since inception, which has required, and will continue to require, significant research and development expenditures. As of December 31, 2004 we had an accumulated deficit of $1.9 billion. These losses, among other things, have had and may have an adverse effect on our stockholders’ equity and working capital.

We believe that the proceeds of the stock offering we completed in November 2003, together with our existing liquidity sources, will satisfy our cash requirements for at least the next twelve months, including the final settlement and payment of C-Cube’s pre-merger tax liabilities. However, we may need to raise additional funds if our expectations are incorrect, to fund our operations, to take advantage of unanticipated strategic opportunities or to strengthen our financial position. The stock offering we completed in November 2003 related to a registration statement on Form S-3 declared effective by the SEC in April 2002. This registration statement will continue to allow Harmonic to issue various types of securities, including common stock, preferred stock, debt securities and warrants to purchase common stock from time to time, up to an aggregate of approximately $73 million, subject to market conditions and our capital needs. Our ability to raise funds may be adversely affected by a number of factors relating to Harmonic, as well as factors beyond our control, including conditions in capital markets and the cable, telecom and satellite industries. There can be no assurance that such financing will be available on terms acceptable to us, if at all.

In addition, from time to time, we review potential acquisitions that would complement our existing product offerings, enhance our technical capabilities or expand our marketing and sales presence. Any future transaction of this nature could require potentially significant amounts of capital to finance the acquisition and related expenses as well as to integrate operations following a transaction, and could require us to issue our stock and dilute existing stockholders. If adequate funds are not available, or are not available on acceptable terms, we may not be able to take advantage of market opportunities, to develop new products or to otherwise respond to competitive pressures.

We may raise additional financing through public or private equity offerings, debt financings or additional corporate collaboration and licensing arrangements. To the extent we raise additional capital by issuing equity securities, our stockholders may experience dilution. To the extent that we raise additional funds through collaboration and licensing arrangements, it may be necessary to relinquish some rights to our technologies or products, or grant licenses on terms that are not favorable to us. If adequate funds are not available, we will not be able to continue developing our products.

If Demand For Our Products Increases More Quickly Than We Expect, We May Be Unable To Meet Our Customers’ Requirements.

Our net sales increased approximately 36% in 2004 from 2003. If demand for our products continues to increase, the difficulty of accurately forecasting our customers’ requirements and meeting these requirements will increase. Forecasting to meet customers’ needs is particularly difficult in connection with newer products. Our ability to meet customer demand depends significantly on the availability of components and other materials as well as the ability of our contract manufacturers to scale their production. Furthermore, we purchase several key components, subassemblies and modules used in the manufacture or integration of our products from sole or limited sources. Our ability to meet customer requirements depends in part on our ability to obtain sufficient volumes of these materials in a timely fashion. Also, in recent years, in response to lower net sales and the prolonged economic recession, we significantly reduced our headcount and other expenses. As a result, we may be unable to respond to customer demand that increases more quickly than we expect. If we fail to meet customers’ supply expectations, our net sales would be adversely affected and we may lose business.

If actual orders are materially lower than the indications we receive from our customers, our ability to manage inventory and expenses may be affected. If we enter into purchase commitments to acquire materials, or expend resources to manufacture products, and such products are not purchased by our customers, our business and operating results could suffer. In this regard, our gross margins and operating results have been in the past adversely affected by significant provisions for excess and obsolete inventories.

We Face Risks Associated With Having Important Facilities And Resources Located In Israel.

Harmonic maintains a facility in Caesarea in the State of Israel with a total of 62 employees as of December 31, 2004, or approximately 11% of our workforce. The employees at this facility consist principally of research and development personnel involved in development of certain products for the CS division. In addition, we have pilot production capabilities at this facility consisting of procurement of subassemblies and modules from Israeli subcontractors and final assembly and test operations. Accordingly, we are directly influenced by the political, economic and military conditions affecting Israel, and any major hostilities involving Israel or the interruption or curtailment of trade between Israel and its trading partners could significantly harm our business. The September 2001 terrorist attacks, the ongoing U.S. war on terrorism and the terrorist attacks and hostilities within Israel have heightened these risks. We cannot assure you that current tensions in the Middle East will not adversely affect our business and results of operations.

In addition, most of our employees in Israel are currently obligated to perform annual reserve duty in the Israel Defense Forces and several have been called for active military duty recently. We cannot predict the effect of these obligations on Harmonic in the future.

The Markets In Which We Operate Are Intensely Competitive And Many Of Our Competitors Are Larger And More Established.

The markets for cable television fiber optics systems and digital video broadcasting systems are extremely competitive and have been characterized by rapid technological change and declining average selling prices. Pressure on average selling prices was particularly severe during the recent economic downturn as equipment suppliers competed aggressively for customers’ reduced capital spending. Harmonic’s competitors in the fiber optics systems business include corporations such as C-Cor, Motorola, and Scientific-Atlanta. In the digital and video broadcasting systems business, we compete broadly with vertically integrated system suppliers including Motorola, Scientific-Atlanta, Tandberg Television and Thomson Multimedia, and in certain product lines with Cisco and a number of smaller companies.

Many of our competitors are substantially larger and have greater financial, technical, marketing and other resources than Harmonic. Many of these large organizations are in a better position to withstand any significant reduction in capital spending by customers in these markets. They often have broader product lines and market focus and may not be as susceptible to downturns in a particular market. In addition, many of our competitors have been in operation longer than we have and therefore have more long standing and established relationships with domestic and foreign customers. We may not be able to compete successfully in the future, which may harm our business.

If any of our competitors’ products or technologies were to become the industry standard, our business could be seriously harmed. For example, new standards for video compression are being introduced and products based on these standards are being developed by Harmonic and certain competitors. If our competitors are successful in bringing these products to market earlier, or if these products are more technologically capable than ours, then our sales could be materially and adversely affected. In addition, companies that have historically not had a large presence in the broadband communications equipment market have begun recently to expand their market share through mergers and acquisitions. The continued consolidation of our competitors could have a significant negative impact on us. Further, our competitors, particularly competitors of our digital and video broadcasting systems business, may bundle their products or incorporate functionality into existing products in a manner that discourages users from purchasing our products or which may require us to lower our selling prices resulting in lower gross margins.

Broadband communications markets are relatively immature, making it difficult to accurately predict the markets’ future growth rates, sizes or technological directions. In view of the evolving nature of these markets, it is possible that cable television operators, telephone companies or other suppliers of broadband wireless and satellite services will decide to adopt alternative architectures or technologies that are incompatible with our current or future products. Also, decisions by customers to adopt new technologies or products are often delayed by extensive evaluation and qualification processes and can result in delays in sales of current products. If we are unable to design, develop, manufacture and sell products that incorporate or are compatible with these new architectures or technologies, our business will suffer.

We Purchase Several Key Components, Subassemblies And Modules Used In The Manufacture Or Integration Of Our Products From Sole Or Limited Sources, And We Are Increasingly Dependent On Contract Manufacturers.

Many components, subassemblies and modules necessary for the manufacture or integration of our products are obtained from a sole supplier or a limited group of suppliers. For example, we depend on LSI Logic for video encoding chips. Our reliance on sole or limited suppliers, particularly foreign suppliers, and our increased reliance on subcontractors since the merger with C-Cube involves several risks, including a potential inability to obtain an adequate supply of required components, subassemblies or modules and reduced control over pricing, quality and timely delivery of components, subassemblies or modules. In particular, certain optical components have in the past been in short supply and are available only from a small number of suppliers, including sole source suppliers. While we expend resources to qualify additional optical component sources, consolidation of suppliers in the industry and the small number of viable alternatives have limited the results of these efforts. We do not generally maintain long-term agreements with any of our suppliers. Managing our supplier and contractor relationships is particularly difficult during time periods in which we introduce new products and during time periods in which demand for our products is increasing, especially if demand increases more quickly than we expect. Furthermore, from time to time we assess our relationship with our contract manufacturers. In late 2003, we entered into a three-year agreement with Plexus Services Corp. as our primary contract manufacturer. We completed the transition during the summer of 2004. Difficulties in managing relationships with current contract manufacturers, could impede our ability to meet our customers’ requirements and adversely affect our operating results. An inability to obtain adequate deliveries or any other circumstance that would require us to seek alternative sources of supply could negatively affect our ability to ship our products on a timely basis, which could damage relationships with current and prospective customers and harm our business. We attempt to limit this risk by maintaining safety stocks of certain components, subassemblies and modules. As a result of this investment in inventories, we have in the past and in the future may be subject to risk of excess and obsolete inventories, which could harm our business, operating results, financial position and liquidity. In this regard, our gross margins and operating results in the past, were adversely affected by significant excess and obsolete inventory charges.

We Need To Effectively Manage Our Operations And The Cyclical Nature Of Our Business.

The cyclical nature of our business has placed, and is expected to continue to place, a significant strain on our personnel, management and other resources. This strain was exacerbated by the acquisition of DiviCom and the subsequent loss of numerous employees, including senior management. In addition, we reduced our work force by approximately 44% between December 31, 2000 and December 31, 2003 due to reduced industry spending and demand for our products. If demand for products increases significantly, we may need to increase our headcount, as we did during 2004, adding 33 employees. Our ability to manage our business effectively in the future, including any future growth, will require us to train, motivate and manage our employees successfully, to attract and integrate new employees into our overall operations, to retain key employees and to continue to improve our operational, financial and management systems.

We May Be Materially Affected By The WEEE And RoHS Directives.

The European Union has finalized the Waste Electrical and Electronic Equipment (WEEE) directive, which regulates the collection, recovery, and recycling of waste from electrical and electronic products, and the Restrictions on the Use of Certain Hazardous Substances in Electrical and Electronic Equipment (RoHS) directive, which bans the use of

We Are Liable For C-Cube’s Pre-Merger Tax Liabilities, Including Tax Liabilities Resulting From The Spin-Off Of Its Semiconductor Business.

Under the terms of the merger agreement with C-Cube, Harmonic is generally liable for C-Cube’s pre-merger tax liabilities. As of December 31, 2004, approximately $15.8 million of pre-merger tax liabilities remained outstanding and are included in accrued liabilities. We are working with LSI Logic, which acquired C-Cube’s spun-off semiconductor business in June 2001 and assumed its obligations, to develop an approach to settle these obligations, a process which has been underway since the merger in 2000. These liabilities represent estimates of C-Cube’s pre-merger tax obligations to various tax authorities in 11 countries. Harmonic paid a further $5.8 million of these tax obligations in February 2005, but is unable to predict when the remaining tax obligations will be paid, or in what amount. The full amount of the estimated obligation has been classified as a current liability. To the extent that these obligations are finally settled for less than the amounts provided, Harmonic is required, under the terms of the merger agreement, to refund the difference to LSI Logic. Conversely, if the settlements are more than the $10.0 million pre-merger tax liability after the February 2005 payments, LSI Logic is obligated to reimburse Harmonic.

The merger agreement stipulates that Harmonic will be indemnified by the spun-off semiconductor business if the cash reserves are not sufficient to satisfy all of C-Cube’s tax liabilities for periods prior to the merger. If for any reason, the spun-off semiconductor business does not have sufficient cash to pay such taxes, or if there are additional taxes due with respect to the non-semiconductor business and Harmonic cannot be indemnified by LSI Logic, Harmonic generally will remain liable, and such liability could have a material adverse effect on our financial condition, results of operations or cash flows.

We May Be Subject To Risks Associated With Other Acquisitions.

We have made, continue to consider making and may make investments in complementary companies, products or technologies. For example, on February 25, 2005, we acquired all of the issued and outstanding shares of Broadcast Technologies Ltd., a private U.K. company. In connection with this and other acquisition transactions, we could have difficulty assimilating or retaining the acquired companies’ key personnel and operations, integrating the acquired technology or products into ours or complying with internal control requirements of the Sarbanes-Oxley Act as a result of an acquisition. We also may face challenges in achieving the strategic objectives, cost savings or other benefits from these proposed acquisitions and difficulties in expanding our management information systems to accommodate the acquired business. These difficulties could disrupt our ongoing business, distract our management and employees and significantly increase our expenses. Moreover, our operating results may suffer because of acquisition-related expenses, amortization of intangible assets and impairment of acquired goodwill or intangible assets. Furthermore, we may have to incur debt or issue equity securities to pay for any future acquisitions, or to provide for additional working capital requirements, the issuance of which could be dilutive to our existing shareholders. If we are unable to successfully address any of these risks, our business, financial condition or operating results could be harmed.

Cessation Of The Development And Production Of Video Encoding Chips By C-Cube’s Spun-off Semiconductor Business May Adversely Impact Us.

The DiviCom business and C-Cube semiconductor business (acquired by LSI Logic in June 2001) collaborated on the production and development of two video encoding microelectronic chips prior to the merger. In connection with the merger, Harmonic and the spun-off semiconductor business entered into a contractual relationship under which Harmonic has access to certain of the spun-off semiconductor business technologies and products which the DiviCom business previously depended for its product and service offerings. The current term of this agreement is through October 2005, with automatic annual renewal unless terminated by either party in accordance with the

Our Failure To Adequately Protect Our Proprietary Rights May Adversely Affect Us.

We currently hold 39 issued U.S. patents and 19 issued foreign patents, and have a number of patent applications pending. Although we attempt to protect our intellectual property rights through patents, trademarks, copyrights, licensing arrangements, maintaining certain technology as trade secrets and other measures, we cannot assure you that any patent, trademark, copyright or other intellectual property rights owned by us will not be invalidated, circumvented or challenged, that such intellectual property rights will provide competitive advantages to us or that any of our pending or future patent applications will be issued with the scope of the claims sought by us, if at all. We cannot assure you that others will not develop technologies that are similar or superior to our technology, duplicate our technology or design around the patents that we own. In addition, effective patent, copyright and trade secret protection may be unavailable or limited in certain foreign countries in which we do business or may do business in the future.

We believe that patents and patent applications are not currently significant to our business, and investors therefore should not rely on our patent portfolio to give us a competitive advantage over others in our industry. We believe that the future success of our business will depend on our ability to translate the technological expertise and innovation of our personnel into new and enhanced products. We generally enter into confidentiality or license agreements with our employees, consultants, vendors and customers as needed, and generally limit access to and distribution of our proprietary information. Nevertheless, we cannot assure you that the steps taken by us will prevent misappropriation of our technology. In addition, we have taken in the past, and may take in the future, legal action to enforce our patents and other intellectual property rights, to protect our trade secrets, to determine the validity and scope of the proprietary rights of others, or to defend against claims of infringement or invalidity. Such litigation could result in substantial costs and diversion of resources and could negatively affect our business, operating results, financial position or cash flows.

In order to successfully develop and market certain of our planned products for digital applications, we may be required to enter into technology development or licensing agreements with third parties. Although many companies are often willing to enter into technology development or licensing agreements, we cannot assure you that such agreements will be negotiated on terms acceptable to us, or at all. The failure to enter into technology development or licensing agreements, when necessary, could limit our ability to develop and market new products and could cause our business to suffer.

We Or Our Customers May Face Intellectual Property Infringement Claims From Third Parties.

Harmonic’s industry is characterized by the existence of a large number of patents and frequent claims and related litigation regarding patent and other intellectual property rights. In particular, leading companies in the telecommunications industry have extensive patent portfolios. From time to time, third parties, including these leading companies, have asserted and may assert exclusive patent, copyright, trademark and other intellectual property rights against us or our customers. Indeed, a number of third parties, including leading companies, have asserted patent rights to technologies that are important to us.

On July 3, 2003, Stanford University and Litton Systems filed a complaint in U.S. District Court for the Central District of California alleging that optical fiber amplifiers incorporated into certain of Harmonic’s products infringe U.S. Patent No. 4,859,016. This patent expired in September 2003. The complaint seeks injunctive relief, royalties and damages. Harmonic has not been served in the case. Harmonic continues to evaluate its position with respect to this patent and has engaged in discussions with the plaintiff regarding potential settlement of the matter. At this time, Harmonic is unable to determine whether Harmonic will be able to settle this matter on reasonable terms or at all, nor can Harmonic predict the impact of an adverse outcome of this litigation if Harmonic elects to defend against it. Consequently, Harmonic has made no provision in its financial statements for the outcome of a negotiated

Our suppliers and customers may receive similar claims. We have agreed to indemnify some of our suppliers and customers for alleged patent infringement. The scope of this indemnity varies, but, in some instances, includes indemnification for damages and expenses (including reasonable attorney’s fees).

We Are The Subject Of Securities Class Action Claims And Other Litigation Which, If Adversely Determined, Could Harm Our Business And Operating Results.

Between June 28 and August 25, 2000, several actions alleging violations of the federal securities laws by Harmonic and certain of its officers and directors (some of whom are no longer with Harmonic) were filed in or removed to the U.S. District Court for the Northern District of California. The actions subsequently were consolidated.

A consolidated complaint, filed on December 7, 2000, was brought on behalf of a purported class of persons who purchased Harmonic’s publicly traded securities between January 19 and June 26, 2000. The complaint also alleged claims on behalf of a purported subclass of persons who purchased C-Cube securities between January 19 and May 3, 2000. In addition to Harmonic and certain of its officers and directors, the complaint also named C-Cube Microsystems Inc. and several of its officers and directors as defendants. The complaint alleged that, by making false or misleading statements regarding Harmonic’s prospects and customers and its acquisition of C-Cube, certain defendants violated sections 10(b) and 20(a) of the Securities Exchange Act of 1934. The complaint also alleged that certain defendants violated section 14(a) of the Exchange Act and sections 11, 12(a)(2), and 15 of the Securities Act of 1933 by filing a false or misleading registration statement, prospectus, and joint proxy in connection with the C-Cube acquisition.

On July 3, 2001, the Court dismissed the consolidated complaint with leave to amend. An amended complaint alleging the same claims against the same defendants was filed on August 13, 2001. Defendants moved to dismiss the amended complaint on September 24, 2001. On November 13, 2002, the Court issued an opinion granting the motions to dismiss the amended complaint without leave to amend. Judgment for defendants was entered on December 2, 2002. On December  12, 2002, plaintiffs filed a motion to amend the judgment and for leave to file an amended complaint pursuant to Rules 59(e) and 15(a) of the Federal Rules of Civil Procedure. On June 6, 2003, the Court denied plaintiffs’ motion to amend the judgment and for leave to file an amended complaint. Plaintiffs filed a notice of appeal on July 1, 2003. The U.S. Court of Appeals for the Ninth Circuit heard oral arguments on February 17, 2005, but has not ruled on the appeal yet.

A derivative action purporting to be on behalf of Harmonic was filed against its then-current directors in the Superior Court for the County of Santa Clara on September 5, 2000. Harmonic also was named as a nominal defendant. The complaint is based on allegations similar to those found in the securities class action and claims that the defendants breached their fiduciary duties by, among other things, causing Harmonic to violate federal securities laws. The derivative action was removed to the U.S. District Court for the Northern District of California on September 20, 2000. All deadlines in this action were stayed pending resolution of the motions to dismiss the securities class action. On July 29, 2003, the Court approved the parties’ stipulation to dismiss this derivative action without prejudice and to toll the applicable limitations period. The limitations period is tolled until fourteen days after (1) defendants provide plaintiff with a copy of the mandate issued by the Ninth Circuit in the securities action or (2) either party provides written notice of termination of the tolling period, whichever is first.

A second derivative action purporting to be on behalf of Harmonic was filed in the Superior Court for the County of Santa Clara on May 15, 2003. It alleges facts similar to those previously alleged in the securities class action and the federal derivative action. The complaint names as defendants former and current Harmonic officers and directors, along with former officers and directors of C-Cube Microsystems, Inc., who were named in the securities class action. The complaint also names Harmonic as a nominal defendant. The complaint alleges claims for abuse of control, gross mismanagement, and waste of corporate assets against the Harmonic defendants, and claims for breach of fiduciary duty, unjust enrichment, and negligent misrepresentation against all defendants. On July 22, 2003, the Court approved the parties’ stipulation to stay the case pending resolution of the appeal in the securities class action. Although the parties initially agreed in principle to a dismissal without prejudice on similar terms as in the federal

Based on its review of the complaints filed in the securities class action, Harmonic believes that it has meritorious defenses and intends to defend itself vigorously. There can be no assurance, however, that Harmonic will prevail. No estimate can be made of the possible range of loss associated with the resolution of this contingency and accordingly, Harmonic has not recorded a liability. An unfavorable outcome of this litigation could have a material adverse effect on Harmonic’s business, operating results, financial position or cash flows.

On July 3, 2003, Stanford University and Litton Systems filed a complaint in U.S. District Court for the Central District of California alleging that optical fiber amplifiers incorporated into certain of Harmonic’s products infringe U.S. Patent No. 4,859,016. This patent expired in September 2003. The complaint seeks injunctive relief, royalties and damages. Harmonic has not been served in the case. Harmonic is currently evaluating its position with respect to this patent and has engaged in discussions with the plaintiff regarding potential settlement of the matter. At this time, we are unable to determine whether we will be able to settle this litigation on reasonable terms or at all, nor can we predict the impact of an adverse outcome of this litigation if we elect to defend against it. No estimate can be made of the possible range of loss associated with the resolution of this contingency and accordingly, we have not recorded a liability associated with the outcome of a negotiated settlement or an unfavorable verdict in litigation. An unfavorable outcome of this matter could have a material adverse effect on Harmonic’s business, operating results, financial position or cash flows.

The Terrorist Attacks Of 2001 And The Ongoing Threat Of Terrorism Have Created Great Uncertainty And May Continue To Harm Our Business.

Current conditions in the U.S. and global economies are uncertain. The terrorist attacks in 2001 created many economic and political uncertainties that have severely impacted the global economy. We experienced a further decline in demand for our products after the attacks. The long-term effects of the attacks, the situation in Iraq and the ongoing war on terrorism on our business and on the global economy remain unknown. Moreover, the potential for future terrorist attacks has created additional uncertainty and makes it difficult to estimate how quickly the U.S. and other economies will recover and our business will improve.

We Rely On A Continuous Power Supply To Conduct Our Operations, And Any Electrical And Natural Gas Crisis Could Disrupt Our Operations And Increase Our Expenses.

We rely on a continuous power supply for manufacturing and to conduct our business operations. Interruptions in electrical power supplies in California in the early part of 2001 could recur in the future. In addition, the cost of electricity and natural gas has risen significantly. Power outages could disrupt our manufacturing and business operations and those of many of our suppliers, and could cause us to fail to meet production schedules and commitments to customers and other third parties. Any disruption to our operations or those of our suppliers could result in damage to our current and prospective business relationships and could result in lost revenue and additional expenses, thereby harming our business and operating results.

Our Stock Price May Be Volatile.

The market price of our common stock has fluctuated significantly in the past, and is likely to fluctuate in the future. In addition, the securities markets have experienced significant price and volume fluctuations and the market prices of the securities of technology companies have been especially volatile. Investors may be unable to resell their shares of our common stock at or above their purchase price. In the past, companies that have experienced volatility in the market price of their stock have been the object of securities class action litigation.

Harmonic has provisions in its certificate of incorporation and bylaws, each of which could have the effect of rendering more difficult or discouraging an acquisition deemed undesirable by the Harmonic Board of Directors. These include provisions:

These provisions, alone or together, could delay hostile takeovers and changes in control or management of Harmonic.

In addition, Harmonic has adopted a stockholder rights plan. The rights are not intended to prevent a takeover of Harmonic, and we believe these rights will help Harmonic’s negotiations with any potential acquirers. However, if the Board of Directors believes that a particular acquisition is undesirable, the rights may have the effect of rendering more difficult or discouraging that acquisition. The rights would cause substantial dilution to a person or group that attempts to acquire Harmonic on terms or in a manner not approved by the Harmonic Board of Directors, except pursuant to an offer conditioned upon redemption of the rights.

As a Delaware corporation, Harmonic also is subject to provisions of Delaware law, including Section 203 of the Delaware General Corporation law, which prevents some stockholders holding more than 15% of our outstanding common stock from engaging in certain business combinations without approval of the holders of substantially all of our outstanding common stock.

Any provision of our certificate of incorporation or bylaws, our stockholder rights plan or Delaware law that has the effect of delaying or deterring a change in control could limit the opportunity for Harmonic stockholders to receive a premium for their shares of Harmonic common stock, and could also affect the price that some investors are willing to pay for Harmonic common stock.

Market risk represents the risk of loss that may impact the operating results, financial position, or liquidity of Harmonic due to adverse changes in market prices and rates. Harmonic is exposed to market risk because of changes in interest rates and foreign currency exchange rates as measured against the U.S. Dollar and currencies of Harmonic’s subsidiaries.

Foreign Currency Exchange Risk

Harmonic has a number of international subsidiaries each of whose sales are generally denominated in U.S. dollars. Sales denominated in foreign currencies were approximately 4% of net sales in 2004. In addition, the Company has various international branch offices that provide sales support and systems integration services. Periodically, Harmonic enters into foreign currency forward exchange contracts (“forward contracts”) to manage exposure related to accounts receivable denominated in foreign currencies. Harmonic does not enter into derivative financial instruments for trading purposes. At December 31, 2004, we had a forward exchange contract to sell Euros totaling $0.9 million that matures within the first quarter of 2005. While Harmonic does not anticipate that near-term changes in exchange rates will have a material impact on Harmonic’s operating results, financial position and liquidity, Harmonic

Interest Rate Risk

Exposure to market risk for changes in interest rates relate primarily to Harmonic’s investment portfolio of marketable debt securities of various issuers, types and maturities and to Harmonic’s borrowings under its bank line of credit facility. Harmonic does not use derivative instruments in its investment portfolio, and its investment portfolio only includes highly liquid instruments with an original maturity of less than two years. These investments are classified as available for sale and are carried at estimated fair value, with material unrealized gains and losses reported in other comprehensive income. There is risk that losses could be incurred if Harmonic were to sell any of its securities prior to stated maturity. A 10% change in interest rates would not have had a material impact on financial conditions, results of operations or cash flows for either 2004 or 2003.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a-15(f) of the Exchange Act. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions or that the degree of compliance with the policies or procedures may deteriorate. We assessed the effectiveness of Harmonic’s internal control over financial reporting as of December 31, 2004. In making this assessment, we used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control — Integrated Framework. Based on our assessment using those criteria, we concluded that as of December 31, 2004, Harmonic’s internal control over financial reporting was effective. Our management’s assessment of the effectiveness of our internal control over financial reporting as of December 31, 2004 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which appears on page 48 of this Annual Report on Form 10-K.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of Harmonic Inc.:

We have completed an integrated audit of Harmonic Inc.’s 2004 consolidated financial statements and of its internal control over financial reporting as of December 31, 2004 and audits of its 2003 and 2002 consolidated financial statements in accordance with the standards of the Public Company Accounting Oversight Board (U.S.). Our opinions, based on our audits, are presented below.

Consolidated financial statements

In our opinion, the consolidated financial statements listed in the index appearing under Item 8 (a) present fairly, in all material respects, the financial position of Harmonic Inc. and its subsidiaries at December 31, 2004 and 2003, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2004 in conformity with accounting principles generally accepted in the U.S. of America. 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 of these statements in accordance with the standards of the Public Company Accounting Oversight Board (U.S.). 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 of financial statements includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

Internal control over financial reporting

Also, in our opinion, management’s assessment, included in Management’s Report on Internal Control Over Financial Reporting appearing under Item 8, that the Company maintained effective internal control over financial reporting as of December 31, 2004 based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), is fairly stated, in all material respects, based on those criteria. Furthermore, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2004, based on criteria established in Internal Control — Integrated Framework issued by the COSO. The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express opinions on management’s assessment and on the effectiveness of the Company’s internal control over financial reporting based on our audit. We conducted our audit of internal control over financial reporting in accordance with the standards of the Public Company Accounting Oversight Board (U.S.). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. An audit of internal control over financial reporting includes obtaining an understanding of internal control over financial reporting, evaluating management’s assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we consider necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinions.

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