PART I

ITEM 1. BUSINESS

This Annual Report on Form 10-K may contain, in addition to historical information, certain forward-looking statements that involve significant risks and uncertainties. Our actual results could differ materially from the information set forth in any such forward-looking statements. Factors that could cause or contribute to such differences include those discussed below, as well as those discussed under “Item 1A Risk Factors” and elsewhere in this Annual Report on Form 10-K.

The Company

Ultratech, Inc. (“Ultratech” or “we”) develops, manufactures and markets photolithography and laser processing equipment designed to reduce the cost of ownership for manufacturers of integrated circuits, including advanced packaging processes and various nanotechnology components, thin film head magnetic recording devices (“thin film heads” or “TFHs”), optical networking devices, laser diodes and LEDs (light emitting diodes).

Lithography

We supply step-and-repeat systems based on one-to-one (“1X”) technology to customers located throughout North America, Europe, Japan and the rest of Asia. We believe that our 1X steppers utilizing the Wynne Dyson optical design offer cost and performance advantages, as compared with competitors’ contact aligners or reduction steppers, to semiconductor device manufacturers for applications involving line geometries of 0.75 microns or greater (“non-critical feature sizes”) and to nanotechnology manufacturers.

Advanced packaging for integrated circuits, specifically bump or wafer level chip scale packaging (“CSP”) techniques, require lithography steps in the device fabrication process. We continue to enhance our product offerings for bump, wafer level CSP processing and post passivation lithography (“PPL”). In addition, our steppers are used to manufacture high volume, low cost semiconductors used in a variety of applications such as telecommunications, automotive control systems, power systems and consumer electronics. We also supply 1X photolithography systems to thin film head manufacturers and believe that our steppers offer advantages over certain competitive reduction lithography tools with respect to field size, throughput, specialized substrate handling and cost. Additionally, we supply 1X photolithography equipment to various other nanotechnology markets, where certain technical features, such as high resolution at gh-line wavelengths, depth of focus and special size substrates, may offer advantages over certain competing tools.

Laser Anneal Technology

Device scaling has been the predominant means pursued by the semiconductor industry to achieve the gains in productivity and performance quantified by Moore’s Law. In the past several years, scaled device performance has been compromised because traditional transistor materials such as silicon, silicon dioxide, and polysilicon, have been pushed to their fundamental materials limits. Continued scaling thus requires the introduction of new materials. For example, the traditional gate dielectric has been silicon dioxide and as devices are scaled below 45 nm high K material such as halfnium oxide must be considered because silicon dioxide begins to lose its effectiveness at level below 45nm. These new materials impose added challenges to the methods used to dope and activate silicon to produce very shallow, highly activated junctions. The main challenges regarding short channel effects include achieving maximum activation and minimal diffusion with abrupt junctions.

By leveraging its core competencies in optics engineering and system integration and its extensive knowledge of laser processing, Ultratech introduced the LSA100 laser spike annealing system to enable thermal annealing solutions at the 65 nm technology node and below. This advanced annealing technology provides solutions to the difficult challenge of fabricating ultra-shallow junctions and highly activated source/drain contacts. Laser processing offers the flexibility to operate at near-instantaneous timeframes (microseconds to milliseconds) at temperatures below the melting point of silicon (1412° C). At these temperatures and anneal times, full activation is achieved with negligible diffusion. In addition, Ultratech’s proprietary hardware design minimizes the pattern density effect, reducing absorptivity variations.

Our products and markets are more fully described below.

General Background

The fabrication of devices such as integrated circuits (“semiconductors” or “ICs”) requires a large number of complex processing steps, including deposition, photolithography and etching. Deposition is a process in which a layer of either electrically insulating or electrically conductive material is deposited on the surface of a wafer. Typically deposition is followed by the photolithography imaging process in which the deposited layer is coated with a photosensitive layer called photoresist or resist. Exposure of the resist to an image formed by ultraviolet light results in some of the resist being removed after development. A subsequent etching step selectively removes the deposited material from areas not protected by the remaining resist pattern.

Photolithography is one of the most critical and expensive steps in IC device manufacturing. Photolithography exposure equipment is used to create device features by selectively exposing a light-sensitive polymer coating on the wafer surface, through a photomask containing the master image of a particular device layer. Typically, each exposure results in the patterning of a different deposited layer and therefore, requires a different pattern on the device. Each new device layer must be properly aligned to previously defined layers before imaging takes place, so that structures formed on the wafers are correctly placed, one on top of the other, in order to ensure a functioning device.

Since the introduction of the earliest commercial photolithography tools for IC manufacturing in the early 1960s, a number of tools have been introduced to enable manufacturers to produce increasingly complex devices with virtually zero defects that incorporate progressively finer line widths. In the early 1970s, photolithography tools included contact printers and proximity aligners, which required the photomask to physically contact or nearly contact the wafer in order to transfer the entire pattern during a single exposure. By the mid 1970s, there were also projection scanners, which transferred the device image through reflective optics having a very narrow annular field that spanned the width of the wafer. Exposure was achieved by scanning the entire photomask and wafer in a single, continuous motion across the annular field. Scanners were followed by steppers, which expose a square or rectangular portion of the wafer in a single exposure, then move or “step” the wafer to an adjacent site to repeat the exposure. This stepping process is repeated as often as necessary until the entire wafer has been exposed. By imaging a small area, steppers are able to achieve finer resolution, improved image size control and better alignment between the multiple device layers resulting in higher yield and productivity in certain devices than was possible with earlier tools.

The two principal types of steppers currently in use by the semiconductor industry are reduction steppers, which are the most widely used steppers, and 1X steppers. Reduction steppers, which typically have reduction ratios of four or five-to-one, are tools in which the photomask pattern containing the design is typically four or five times larger than the device pattern that is to be exposed on the wafer surface. In addition, there is now a fourth generation of lithography tools, known as step-and-scan systems, that address device sizes of 0.35 micron and below. In contrast to steppers, which expose the entire field in a

single exposure, step-and-scan systems scan the mask and wafer through a narrow illuminated region to produce one field and repeat this operation over multiple fields to expose the entire wafer.

The principal advantage of reduction steppers and step-and-scan systems is that they may be used in manufacturing steps requiring critical feature sizes and are therefore necessary for manufacturing advanced ICs. 1X steppers, on the other hand, are tools in which the photomask pattern is the same scale as the device pattern that is exposed on the wafer surface. Ultratech’s 1X, Wynne Dyson optics steppers, unlike most reduction steppers, are based on a technology which incorporates both reflective and refractive elements in its imaging system. This design is much simpler than a reduction stepper’s imaging system, which incorporates only refractive elements. As a result, 1X steppers for non-critical features are generally less expensive than the reduction steppers required for critical feature sizes. Because of their optical design, 1X steppers typically are also able to deliver greater exposure energy to the wafer surface, which may result in higher throughput than is achievable with certain reduction steppers in particular applications. However, 1X steppers are currently limited to use in manufacturing steps involving less-critical, larger feature sizes. Accordingly, we believe that sales of these systems are highly dependent upon capacity expansions by our current 1X customers, or by customers making the transition to advanced bump type chips, which employ a different means of electrically connecting the chip to other components.

In the past, manufacturers of ICs and similar devices purchased capital equipment based principally on technological capabilities. In view of the significant capital expenditures required to construct, equip and maintain advanced fabrication facilities, relatively short product cycles and manufacturers’ increasing concern for overall fabrication costs, we believe that manufacturers of ICs with flip chip (bump) packaging now focus on reducing their total cost of ownership. A major component of this cost is the cost of ownership of the equipment used for a particular application in a fabrication facility. Cost of ownership is measured in terms of the costs associated with the acquisition of equipment, as well as factors such as throughput, yield, up-time, service, labor overhead, maintenance, and various other costs of owning and using the equipment. With increasing importance being placed upon a system’s overall cost of ownership, in many cases the system with the most technologically advanced capabilities will not necessarily be the manufacturing system of choice. As part of the focus on cost reduction, we believe that device manufacturers are attempting to extend the useful life and enhance the production capabilities of fabrication facilities by selecting equipment that can replace existing tools while offering better, more cost-effective performance.

In addition to enhancing our current lithography solutions, we have been developing new tools for our existing markets. We have developed a new laser annealing technology for volume production of advanced state of the art devices and are now offering a Laser Processing (“LP”) product. Our first commercial product based on the new LP technology platform employs a process called laser spike annealing (“LSA”), for activating ultra-shallow junctions. This technology is expected to be useful for multiple IC generations. We anticipate that eventually this technology will be superseded by an even faster laser processing technology that will take the processing time below one microsecond, thereby achieving even higher performance characteristics while using almost “zero” thermal budget. As a result, these new LP technologies—for which we have been awarded 42 patents and have 70 patent applications pending—are expected to remove several critical barriers to future device scaling.

junctions. The main challenges regarding short channel effects include achieving maximum activation and minimal diffusion with abrupt junctions.

Products

We currently offer two different series of 1X lithography systems for use in the semiconductor fabrication process: the 1000 Family, which addresses the markets for scanner replacement, high volume/low cost semiconductor fabrication and R&D packaging activities and nanotechnology applications; and the AP series, which was designed to meet the requirements in the advanced packaging market. These steppers currently offer minimum feature size capabilities ranging from 2.0 microns to 0.75 microns.

In advanced packaging, we offer our AP series built on the Unity PlatformTM. These advanced packaging systems were developed for high volume bump and wafer level chip scale packaging (CSP) manufacturing and post passivation lithography applications. In addition, we offer the Prisma-ghi system, which is manufactured on the 1000-series platform, for R&D packaging applications or where wafer volume requirements are not important. These systems provide broadband (ghi-line) exposure or selective exposure (gh or i-line), and are used in conjunction with electroplating to produce a pattern of bumps, or metal connections for flip chip devices. This pattern can be placed in a tight array across the entire die, as opposed to the conventional method of wire bonding which is generally limited to pads on the periphery of the die. This allows manufacturers to shrink the die size. The flip chip device can then be placed in a small outline package or directly on a printed circuit board.

The AP series, consisting of the AP200 & AP300, feature a customer-configurable design that supports flexible manufacturing requirements as well as tool extendibility for multiple device generations. Designed to optimize productivity, the AP systems integrate the proven optics and processing advantages associated with our advanced packaging lithography equipment with the productivity benefits of our new Unity Platform. We believe that these new lithography systems support a lower cost-of-ownership strategy due to significant throughput enhancements, higher reliability, and superior alignment and illumination systems.

The 1000 family is a small field system available with gh-line and i-line illumination options. In semiconductor applications, where we offer the Star 100 as well as the more mature 1500MVS. This platform is typically used in the manufacture of power devices, ASICs, analog devices and compound semiconductors. In addition, this platform is well suited for a number of nanotechnology applications.

Nanotechnology manufacturing combines electronics with mechanics in small devices. We have defined that a nanotechnology device has at least one dimention in the XYZ direction less than 0.1 microns. Examples include accelerometers used to activate air bags in automobiles and membrane pressure sensors used in industrial control systems. These micro-machined devices are manufactured on silicon substrates using photolithography techniques similar to those used for manufacturing semiconductors and thin film head devices. In addition, these systems are used in applications such as LED and laser diodes. In 2002, we introduced the NanoTech product family that consists of the NanoTech 100, NanoTech 160 and NanoTech 190. The NanoTech 160 system utilizes a platform based on the previous 1000 Series steppers, incorporating Dual Side Alignment (“DSA”) capability for applications requiring lithography on both sides of a wafer. The NanoTech 160 is an extension of the model 1600DSA stepper, and enhances the capabilities of the 1000 Series steppers by offering Dual Side Alignment capability, providing customers with a 1X stepper solution for this special processing requirement. Additionally, we believe that our NanoTech steppers offer resolution and depth of focus advantages over alternative technologies to the manufacturers of nanotechnology components.

The NanoTech 190 steppers, have enhanced capabilities directed at TFH backend, or rowbar processing applications. These steppers are used to expose the Air Bearing Surface (ABS) patterns on rowbars.

We also sell upgrades to systems in our installed base and refurbished systems. These refurbished systems typically have a purchase price that is lower than the purchase price for our new systems.

We also offer an advanced laser-based thermal annealing tool, the LSA100, built on essentially the same Unity Platform. Thermal annealing is used by the semiconductor industry for a variety of process steps, including activation of implanted impurities, dielectric film formation, formation of silicides and stabilization of copper grain structure. Annealing tools currently in use by manufacturers of semiconductor devices are furnaces and rapid thermal annealing, or Rapid Thermal Processing (“RTP”), systems. We believe there is a need for tools that anneal at higher temperatures for shorter periods of time and that our laser annealing tools may ultimately provide this capability to the industry. The near-term application of our laser-based thermal annealing tools is anticipated to be in the area of source/drain dopant activation. However, we are also researching the use of these tools for other applications. In 2005 we shipped and revenued production systems for multiple customers.

Research, Development and Engineering

The semiconductor and nanotechnology industries are subject to rapid technological change and new product introductions and enhancements. We believe that continued and timely development and introduction of new and enhanced systems to serve these markets is essential for us to maintain our competitive position. We have made and continue to make substantial investments in the research and development of our core optical technology, which we believe is critical to our financial results. We intend to continue to develop our technology and to develop innovative products and product features to meet customer demands. Current engineering projects include: continued research and development and process insertion for our laser processing technologies and continued development of our 1X stepper products. Other research and development efforts are currently focused on performance enhancement and development of new features for existing systems, both for inclusion as a standard component in our systems and to meet special customer order requirements; other efforts include reliability improvement; and manufacturing cost reductions. These research and development efforts are undertaken, principally, by our research, development and engineering organizations and costs are generally expensed as incurred. Other operating groups within our Company support our research, development and engineering efforts, and the associated costs are charged to those organizations and expensed as incurred.

We work with many customers to jointly develop technology required to manufacture advanced devices or to lower the customer’s cost of ownership. We also have a worldwide engineering support organization including reticle engineering, photo processing capability and applications support.

We have historically devoted a significant portion of our financial resources to research and development programs and expect to continue to allocate significant resources to these efforts in the future. As of December 31, 2005, we had approximately 66 full-time employees engaged in research, development, and engineering. For 2005, 2004 and 2003, total research, development, and engineering expenses were approximately $27.0 million, $25.9 million and $21.3 million, respectively, and represented 22%, 24% and 21% of our net sales, respectively.

Sales and Service

We market and sell our products in North America, Europe, Japan, Taiwan and the rest of Asia principally through our direct sales organization. We also have service personnel based throughout the United States, Europe, Japan and the rest of Asia.

Ultratech believes that as semiconductor and nanotechnology device manufacturers produce increasingly complex devices, they will require an increased level of support. Global support capability as well as product reliability, performance, yield, cost, uptime and mean time between failures are increasingly important factors by which customers evaluate potential suppliers of photolithography equipment. We believe that the strength of our worldwide service and support organization is an important factor in our ability to sell our systems, maintain customer loyalty and reduce the maintenance costs of our systems. In addition, we believe that working with our suppliers and customers is necessary to ensure that our systems are cost effective, technically advanced and designed to satisfy customer requirements.

We support our customers with field service, applications, technical service engineers and training programs. We provide our customers with comprehensive support and service before, during and after delivery of our systems. To support the sales process and to enhance customer relationships, we work closely with prospective customers to develop hardware, software and applications test specifications and benchmarks, and often design customized applications to enable prospective customers to evaluate our equipment for their specific needs. Prior to shipment, our support personnel typically assist the customer in site preparation and inspection, and provide customers with training at our facilities or at the customer’s location. We currently offer our customers various courses of instruction on our systems, including instructions in system hardware, software and applications tools for optimizing our systems to fit a customer’s particular needs. Our customer training program also includes instructions in the maintenance of our systems. Our field support personnel work with the customer’s employees to install the system and demonstrate system readiness. Technical support is also available via telephone and through on-site Ultratech personnel.

In general, we warrant our new systems against defects in design, materials and workmanship for one year. We offer our customers additional support after the warranty period for a fee in the form of service contracts for specified time periods. Service contracts include various options such as priority response, planned preventive maintenance, scheduled one-on-one training, daily on-site support, and monthly system and performance analysis.

Manufacturing

We perform all of our manufacturing activities (final assembly, system testing and certain subassembly) in clean room environments totaling approximately 27,000 square feet located in San Jose, California. Performing manufacturing operations in California exposes us to a higher risk of natural disasters, including earthquakes. In addition, in the past California has experienced power shortages, which have interrupted our operations. Such shortages could occur in the future and could again interrupt our

operations resulting in product shipment delays, increased costs and other problems, any of which could have a material adverse effect on our business, customer relationships and results of operations. We are not insured against natural disasters and power shortages and the occurrence of such an event could have a material adverse impact our results of operations.

Our manufacturing activities consist of assembling and testing components and subassemblies, which are then integrated into finished systems. We rely on a limited number of outside suppliers and subcontractors to manufacture certain components and subassemblies. We order one of the most critical components of our technology, the glass for our 1X lenses, from external suppliers. We design the 1X lenses and provide the lens specifications and the glass to other suppliers, who then machine the lens elements. We then assemble and test the optical 1X lenses. We have recorded the critical parameters of each of our optical lenses sold since 1982, and believe that such information enables us to supply lenses to our customers that match the characteristics of our customers’ existing lenses.

We procure some of our other critical systems’ components, subassemblies and services from single outside suppliers or a limited group of outside suppliers in order to ensure overall quality and timeliness of delivery. Many of these components and subassemblies have significant production lead times. To date, we have been able to obtain adequate services and supplies of components and subassemblies for our systems in a timely manner. However, disruption or termination of certain of these sources could result in a significant adverse impact on our ability to manufacture our systems. This, in turn, would have a material adverse effect on our business, financial condition and results of operations. Our reliance on a sole or a limited group of suppliers and our reliance on subcontractors involve several risks, including a potential inability to obtain an adequate supply of required components due to the suppliers’ failure or inability to provide such components in a timely manner, or at all, and reduced control over pricing and timely delivery of components. Although the timeliness, yield and quality of deliveries to date from our subcontractors have been acceptable, manufacture of certain of these components and subassemblies is an extremely complex process, and long lead-times are required. Any inability to obtain adequate deliveries or any other circumstance that would require us to seek alternative sources of supply or to manufacture such components internally could delay our ability to ship our products, which could damage relationships with current and prospective customers and have a material adverse effect on our business, financial condition and results of operations.

We maintain a company-wide quality program. Our operations achieved ISO 9001:1994 certification in 1996 and ISO 14001:1996 certification in March 2001. Our ISO 9001 certification was upgraded to the ISO 9001:2000 standard in January 2002. All certifications have been maintained uninterrupted through the date of this report.

Competition

The capital equipment industry in which we operate is intensely competitive. A substantial investment is required to install and integrate capital equipment into a semiconductor, semiconductor packaging or nanotechnology device production line. We believe that once a device manufacturer or packaging subcontractor has selected a particular supplier’s capital equipment, the manufacturer generally relies upon that equipment for the specific production line application and, to the extent possible, subsequent generations of similar products. Accordingly, it is difficult to achieve significant sales to a particular customer once another supplier’s capital equipment has been selected.

Advanced Packaging

their current products and to introduce new products with improved price and performance characteristics. This could cause a decline in sales or loss of market acceptance of our steppers in our served markets, and thereby materially adversely affect our business, financial condition and results of operations. Enhancements to, or future generations of, competing products may be developed that offer superior cost of ownership and technical performance features. We believe that to be competitive will require significant financial resources in order to continue to invest in new product development, to invest in new features and enhancements to existing products, to introduce new generation stepper systems in our served markets on a timely basis, and to maintain customer service and support centers worldwide. In marketing our products, we may also face competition from suppliers employing other technologies. In addition, increased competitive pressure has led to intensified price-based competition in certain of our markets, resulting in lower prices and margins. Should these competitive trends continue, our business, financial condition and operating results may be materially adversely affected.

We have obtained a leadership position in the advanced packaging market. Our primary competition in this market comes from contact aligners offered by companies such as Suss Microtec. Although contact and proximity aligners generally have lower purchase prices than 1X steppers, 1X steppers offer lower operating costs and total cost of ownership in most applications. We believe that most device manufacturers and wafer bump foundries choose 1X steppers due to the yield improvement offered by the use of non-contact lithography. Ushio, a Japanese semiconductor equipment company has also introduced a 1X refractive stepper for the advanced packaging market. However, we believe 1X refractive steppers do not offer the same productivity and cost saving advantages as our 1X stepper based on the Wynne Dyson optical design. Tamarack has a 1X scanner for wafer bumping applications. We believe that Tamarack’s 1X scanners have higher operating costs as compared to our 1X steppers. In addition to contact and proximity aligners, Ultratech also faces competition from the reduction stepper market. While reduction steppers are typically more expensive and offer less flexibility in processing thick resists, some device manufacturers may consider this technology option.

Laser Processing

With respect to our laser annealing technologies, marketed under the LSA100 product name, our primary competition comes from companies such as Applied Materials, Inc., and Dainippon Screen Manufacturing Co., LTD. Many of these companies offer products utilizing rapid thermal processing (RTP), which is the current manufacturing technology. RTP does not prevent semiconductor device manufacturers from scaling the lateral dimensions of their transistors to obtain improved performance, but diffusion resulting from the time scales associated with RTP seriously limits the vertical dimension of the junctions. Faster annealing times result in shallower and more abrupt junctions and faster transistors. We believe our annealing technology results in faster transistors for a given size. We believe that RTP manufacturers recognize the need to reduce thermal cycle times and are working toward this goal. Several companies have published papers on annealing tools that incorporate flash lamp anneal (FLA) technology in order to reduce annealing times and increase anneal temperatures. Developers of FLA technology claim to have overcome annealing difficulties at the 65nm node. This technique, which employs xenon flash lamps, has shown improvements over RTP in junction depth and sheet resistance, but we believe FLA will suffer from pattern-related non-uniformities and could require additional, costly processes to reduce the reflectivity of different areas within the chip or wafer. Our proprietary laser processing solution has been specifically developed to provide junction annealing on near-instantaneous timescales, while maintaining low sheet resistance. LSA, our first implementation of laser processing, activates dopants in the microsecond-to-millisecond time frame without melting. Our research indicates that, at temperatures just below the melting point of silicon, time durations in the microsecond to millisecond range, are required to achieve full activation, and dopant diffusion is minimal.

In July 2000, we licensed certain rights to our then existing laser processing technology, with reservations, to a competing manufacturer of semiconductor equipment. We presently anticipate that this company and others intend to offer laser annealing tools to the semiconductor industry that will compete with our offerings. We believe that Applied Materials is working to introduce a laser based system, although we believe their solution will suffer from the same pattern-related non-uniformities as flash lamps.

Intellectual Property Rights

Although we attempt to protect our intellectual property rights through patents, copyrights, trade secrets and other measures, we believe that our success will depend more upon the innovation, technological expertise and marketing abilities of our employees. Nevertheless, we have a policy of seeking patents when appropriate on inventions resulting from our ongoing research and development and manufacturing activities. We own 107 United States and foreign patents, which expire on dates ranging from April 2006 to April 2023 and have 97 United States and foreign patent applications pending. We also have various registered trademarks and copyright registrations covering mainly software programs used in the operation of our systems. We also rely upon trade secret protection for our confidential and proprietary information. We may not be able to protect our technology adequately and competitors may be able to develop similar technology independently. Our pending patent applications may not be issued or U.S. or foreign intellectual property laws may not protect our intellectual property rights. In addition, litigation may be necessary to enforce our patents, copyrights or 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. Such litigation has resulted in, and in the future could result in, substantial costs and diversion of resources and could have a material adverse effect on our business, financial condition and results of operations, regardless of the outcome of the litigation. Patents issued to us may be challenged, invalidated or circumvented and the rights granted thereunder may not provide competitive advantages to us. Furthermore, others may independently develop similar technology or products, or, if patents are issued to us, design around the patents issued to us. Invalidation of our patents related to those technologies could allow our competitors to more effectively compete against us, which could result in less revenue for us.

On February 29, 2000, we filed lawsuits asserting patent infringement and related claims against Nikon, Canon, and ASML in the U.S. District Court for the Eastern District of Virginia. In April 2000, we reached a settlement with Nikon, and in September 2001, we reached a settlement with Canon. In the patent litigation against ASML, a jury trial was conducted during the three-month period ended July 2, 2005. The jury reached a verdict that the patent was infringed, but that the asserted claims of the patent were invalid. We filed a post-trial motion for a new trial and for judgment as a matter of law in our favor. ASML also filed a motion for judgment as a matter of law seeking to invalidate three of the asserted claims for lack of enablement and requested that the court awards costs. On February 13th, 2006, the Court denied our post-trial motions, including the motion for a new trial, and entered judgment in favor of ASML invalidating three claims of the patent for lack of enablement. The Court also awarded ASML approximately $330,000 in costs. Ultratech intends to appeal the final judgment.

On July 11, 2003, we filed a lawsuit against a Southern California company asserting infringement of certain claims related to U.S. patent No. 5,621,813 in the U.S. District Court in and for the Northern District of California. On May 17, 2005, the court found the subject patent to be invalid. We have appealed this decision and that appeal is pending. The defendant subsequently brought a motion for reimbursement of its attorneys’ fees and costs in a total asserted amount of approximately $2 million. We opposed this motion, and on October 12, 2005, the District Court denied the defendant’s request for attorneys’ fees in its entirety. On November 3, 2005, the defendant filed a notice of appeal with respect to the court’s ruling on its motion for attorneys’ fees.

We have from time to time been notified of claims that we may be infringing intellectual property rights possessed by third parties. We believe that the outcome of these matters will not be material to our business or financial condition.

Infringement claims by third parties or claims for indemnification resulting from infringement claims may be asserted in the future and such assertions could materially adversely affect our business, financial condition and results of operations, regardless of the outcome of any litigation. With respect to any such future claims, we may seek to obtain a license under the third party’s intellectual property rights. However, a license may not be available on reasonable terms or at all. We could decide, in the alternative, to resort to litigation to challenge such claims. Such challenges could be expensive and time consuming and could materially adversely affect our business, financial condition and results of operations, regardless of the outcome of any litigation.

Environmental Regulations

We are subject to a variety of governmental regulations relating to the use, storage, discharge, handling, emission, generation, manufacture and disposal of toxic or other hazardous substances. We believe that we are currently in compliance in all material respects with such regulations and that we have obtained all necessary environmental permits to conduct our business. Nevertheless, the failure to comply with current or future regulations could result in substantial fines being imposed on us, suspension of production, alteration of the manufacturing process or cessation of operations. Such regulations could require us to acquire expensive remediation equipment or to incur substantial expenses to comply with environmental regulations. Any failure by us to control the use, disposal or storage of, or adequately restrict the discharge of, hazardous or toxic substances could subject us to significant liabilities.

Customers, Applications and Markets

We sell our systems to semiconductor, advanced packaging, thin film head, ink jet printer/accelerometer and various other nanotechnology manufacturers located throughout North America, Europe, Japan, Taiwan and the rest of Asia. Semiconductor manufacturers have purchased the 1000 Series steppers, the AP series of steppers, and the NanoTech steppers for the fabrication and/or packaging of microprocessors, microcontrollers, DRAMs, ASICs and a host of other devices. Such systems could be used in mix-and-match applications with other lithography tools, as replacements for scanners and contact proximity printers, in packaging for flip chip applications and for high volume, low cost, less critical feature size production. In addition to the business risks associated with dependence on major customers, these significant customer concentrations have in the past resulted in significant concentrations of accounts receivable. These significant and concentrated receivables expose us to additional risks, including the risk of default by one or more customers representing a significant portion of our total receivables. If we were required to take additional accounts receivable reserves, our business, financial condition and results of operations would be materially adversely affected.

On a market application basis, sales to the semiconductor industry, primarily for advanced packaging applications, accounted for approximately 79% of system revenue for the year ended December 31, 2005, as compared to 75% for each of the years ended December 31, 2004 and 2003. During 2005, 2004 and 2003, approximately 21%, 25% and 25%, respectively, of our systems revenue was derived from sales to nanotechnology manufacturers, including micro systems, thin film head and optical networking device manufacturers. Our future results of operations and financial position would be materially adversely impacted by a downturn in any of these market segments, or by loss of market share in any of these segments.

International sales accounted for approximately 69%, 65% and 61% of total net sales for the years 2005, 2004 and 2003, respectively, with Japan representing 13%, 32% and 28% of sales for those same years.

Sales of our systems depend, in significant part, upon the decision of a prospective customer to increase manufacturing capacity or to restructure current manufacturing facilities, either of which typically involves a significant commitment of capital. Many of our customers in the past have cancelled the development of new manufacturing facilities and have substantially reduced their capital equipment budgets. In view of the significant investment involved in a system purchase, we have experienced and may continue to experience delays following initial qualification of our systems as a result of delays in a customer’s approval process. Additionally, we are presently receiving orders for systems that have lengthy delivery schedules, which may be due to longer production lead times or a result of customers’ capacity scheduling requirements. For these and other reasons, our systems typically have a lengthy sales cycle during which we may expend substantial funds and management effort in securing a sale. Lengthy sales cycles subject us to a number of significant risks, including inventory obsolescence and fluctuations in operating results, over which we have little or no control. In order to maintain or exceed our present level of net sales, we are dependent upon obtaining orders for systems that will ship and be accepted in the current period. We may not be able to obtain those orders.

Backlog

We schedule production of our systems based upon order backlog, informal customer commitments and general economic forecasts for our targeted markets. We include in our backlog all accepted customer orders for our systems with assigned shipment dates within one year, as well as all orders for service, spare parts and upgrades, in each case, that management believes to be firm. However, all orders are subject to cancellation or rescheduling by the customer with limited or no penalties. Because of changes in system delivery schedules, cancellations of orders and potential delays in system shipments, our backlog at any particular date may not necessarily be representative of actual sales for any succeeding period. As of December 31, 2005 and 2004, our backlog was approximately $108.8 million and $82.5 million, respectively, including $0.0 million and $1.0 million, respectively, of products shipped but not yet installed and accepted. Cancellation, deferrals or rescheduling of orders by these customers would have a material adverse impact on our future results of operations.

Employees

At December 31, 2005, we had approximately 328 full-time employees, including 66 engaged in research, development, and engineering, 39 in sales and marketing, 100 in customer service and support, 73 in manufacturing and 50 in general administration and finance. We believe our future success depends, in large part, on our ability to attract and retain highly skilled employees. None of our employees are covered by a collective bargaining agreement. We have, however, entered into employment agreements with a limited number of our employees, including our executive officers. We consider our relationships with our employees to be good.

Item 1A Risk Factors

In addition to risks described in the foregoing discussions under “Business,” including but not limited to those under “Products,” “Research, Development and Engineering,” “Sales and Service,”

“Manufacturing,” “Competition,” “Intellectual Property Rights,” “Environmental Regulations,” “Customers, Applications and Markets,” “Backlog,” and “Employees,” the following risks apply to us and our business:

We currently spend, and expect to continue to spend, significant resources to develop, introduce and commercialize our laser processing systems and AP wafer stepper products, and we may not be successful in achieving or increasing sales of these products.

Currently, we are devoting significant resources to the development, introduction and commercialization of our laser products as well as our lithography wafer steppers. We intend to continue to develop these products and technologies during 2006, and will continue to incur significant operating expenses in the areas of research, development and engineering, manufacturing and general and administrative costs in order to develop, produce and support these new products. Additionally, gross profit margins and inventory levels may be further adversely impacted in the future by costs associated with the initial production of our laser processing systems and by future generations of our 1X lithography systems. Introduction of new products generally involves higher installation costs and product performance uncertainties that could delay customer acceptance of our systems, resulting in a delay in recognizing revenue associated with those systems and a reduction in gross margins. These costs include, but are not limited to, additional manufacturing overhead, additional inventory write-offs, costs of demonstration systems and facilities, costs associated with the establishment of additional after-sales support organizations. Additionally, operating expenses may increase, relative to sales, as a result of adding additional marketing and administrative personnel, among other costs, to support our new products. If we are unable to achieve significantly increased net sales or if our sales fall below expectations, our operating results will be materially adversely affected.

Our ability to commercialize our laser processing technologies depends on our ability to demonstrate a manufacturing-worthy tool. We do not presently have in-house capability to fabricate devices. As a result, we must rely on partnering with semiconductor companies to develop the anneal process. The development of new process technologies is largely dependent upon our ability to interest potential customers in working on joint process development. Our ability to deliver timely solutions is also limited by wafer turnaround at the potential customer’s fabrication facility.

Our sales cycle is typically lengthy and involves a significant commitment of capital by our customers, which has subjected us, and is likely to continue to subject us, to delays in customer acceptances of our products and other risks, any of which could adversely impact our results of operations by, among other things, delaying recognition of revenue with respect to those orders and resulting in increased installation, qualification and similar costs.

We may not be successful in protecting our intellectual property rights or we could be found to have infringed the intellectual property rights of others, either of which could weaken our competitive position and adversely affect our results of operations.

Although we attempt to protect our intellectual property rights through patents, copyrights, trade secrets and other measures, we believe that our success will depend more upon the innovation, technological expertise and marketing abilities of our employees. Nevertheless, we have a policy of seeking patents when appropriate on inventions resulting from our ongoing research and development and manufacturing activities. We own 107 United States and foreign patents, which expire on dates ranging from April 2006 to April 2023 and have 97 United States and foreign patent applications pending. In addition, we have various registered trademarks and copyright registrations covering mainly software programs used in the operation of our systems. We also rely upon trade secret protection for our confidential and proprietary information. We may not be able to protect our technology adequately and competitors may be able to develop similar technology independently. Our pending patent applications may not be issued or U.S. or foreign intellectual property laws may not protect our intellectual property rights. In addition, litigation may be necessary to enforce our patents, copyrights or 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. Such litigation has resulted in, and in the future could result in, substantial costs and diversion of resources and could have a material adverse effect on our business, financial condition and results of operations, regardless of the outcome of the litigation. Patents issued to us may be challenged, invalidated or circumvented and the rights granted thereunder may not provide competitive advantages to us. Furthermore, others may independently develop similar technology or products, or, if patents are issued to us, design around the patents issued to us. Invalidation of our patents related to those technologies could allow our competitors to more effectively compete against us, which could result in less revenue for us.

condition and results of operations, regardless of the outcome of any litigation. With respect to any such future claims, we may seek to obtain a license under the third party’s intellectual property rights. However, a license may not be available on reasonable terms or at all. We could decide, in the alternative, to resort to litigation to challenge such claims. Such challenges could be expensive and time consuming and could materially adversely affect our business, financial condition and results of operations, regardless of the outcome of any litigation.

We operate in a highly competitive industry in which customers are required to invest substantial resources in each product, which makes it difficult to achieve significant sales to a particular customer once another vendor’s equipment has been purchased by that customer.

We experience competition in advanced packaging from various proximity aligner companies such as Suss Microtec AG (Suss Microtec) and projection companies such as Ushio, Inc. (Ushio). In nanotechnology, we experience competition from proximity aligner companies, such as Suss Microtec, as well as other stepper manufacturers who have developed or are developing tools specifically designed for nanotechnology applications. We expect our competitors to continue to improve the performance of their current products and to introduce new products with improved price and performance characteristics. This could cause a decline in sales or loss of market acceptance of our steppers in our served markets, and thereby materially adversely affect our business, financial condition and results of operations. Enhancements to, or future generations of, competing products may be developed that offer superior cost of ownership and technical performance features.

With respect to our laser annealing technologies, marketed under the LSA100 product name, the primary competition comes from companies such as Applied Materials, Inc., and Dainippon Screen Manufacturing Co., LTD. Many of these companies offer products utilizing rapid thermal processing, or RTP, which is the current prevailing manufacturing technology. RTP does not prevent semiconductor device manufacturers from scaling the lateral dimensions of their transistors to obtain improved performance, but diffusion resulting from the time scales associated with RTP limits the vertical dimension of the junctions. Faster annealing times result in shallower and more abrupt junctions and faster transistors. We believe our annealing technology results in faster transistors for a given size. We believe that RTP manufacturers recognize the need to reduce thermal cycle times and are working toward this goal. In July 2000, we licensed certain rights to our then existing laser processing technology, with reservations, to a competing manufacturer of semiconductor equipment. We presently anticipate that this company will offer laser-annealing tools to the semiconductor industry that will compete with our offerings.

Another potential advanced annealing solution utilizes flash lamp annealing technology, or FLA. Several companies have published papers on annealing tools that incorporate flash lamp technology in order to reduce annealing times and increase anneal temperatures. Developers of FLA technology claim to have overcome annealing difficulties at the 65nm node. This technique, which employs xenon flash lamps, has shown improvements over RTP in junction depth and sheet resistance, but we believe FLA will suffer from pattern-related non-uniformities and could require additional, costly processes to reduce the reflectivity of different areas within the chip or wafer. Our proprietary laser processing solution has been specifically developed to provide junction annealing on near-instantaneous time-scales, while maintaining

low sheet resistance. Laser spike annealing, the first implementation of laser processing, activates dopants in the microsecond-to-millisecond time frame without melting. Our research indicates that, at temperatures just below the melting point of silicon, time durations in the microsecond to millisecond range, are required to achieve full activation, and dopant diffusion is minimal.

Additionally, competition to our laser processing products may come from other laser annealing tools, including those presently being used by the flat panel display industry to re-crystallize silicon. Manufacturers of these tools may try to extend the use of their technologies to semiconductor device applications.

We believe that in order to be competitive, we will need to continue to invest significant financial resources in new product development, new features and enhancements to existing products, the introduction of new stepper systems in our served markets on a timely basis, and maintaining customer service and support centers worldwide. In marketing our products, we may also face competition from vendors employing other technologies. In addition, increased competitive pressure has led to intensified price-based competition in certain of our markets, resulting in lower prices and margins. Should these competitive trends continue, our business, financial condition and operating results may be materially adversely affected.

We sell our products primarily to a limited number of customers and to customers in a limited number of industries, which subjects us to increased risks related to the business performance of our customers, and therefore their need for our products, and the business cycles of the markets into which we sell.

Historically, we have sold a substantial portion of our systems to a limited number of customers. In 2005, 2004, and 2003, Intel Corporation accounted for 13%, 10%, and 26% of our net sales. We expect that sales to a relatively few customers will continue to account for a high percentage of our net sales in the foreseeable future and believe that our financial results depend in significant part upon the success of these major customers and our ability to meet their future capital equipment needs. Although the composition of the group comprising our largest customers may vary from period to period, the loss of a significant customer or any reduction in orders by a significant customer, including reductions due to market, economic or competitive conditions in the semiconductor, semiconductor packaging or nanotechnology industries or in the industries that manufacture products utilizing integrated circuits, thin film heads or other nanotechnology components, would likely have a material adverse effect on our business, financial condition and results of operations. Our ability to maintain or increase our sales in the future depends, in part, on our ability to obtain orders from new customers as well as the financial condition and success of our existing customers, the semiconductor and nanotechnology industries and the economy in general.

In addition to the business risks associated with dependence on a few major customers, these significant customer concentrations have in the past resulted in significant concentrations of accounts receivable. These significant and concentrated receivables expose us to additional risks, including the risk of default by one or more customers representing a significant portion of our total receivables. If we were required to take additional accounts receivable reserves, our business, financial condition and results of operations would be materially adversely affected.

On a market application basis, sales to the semiconductor industry, primarily for advanced packaging applications, accounted for approximately 79% and 75% of system revenue for the years ended 2005 and 2004, respectively. In 2005 and 2004, approximately 21% and 25%, respectively, of our systems revenue was derived from sales to nanotechnology manufacturers, including micro systems, thin film head and optical device manufacturers. Our future operating results and financial condition would be materially adversely impacted by a downturn in any of these market segments, or by loss of market share in any of these segments. A growing portion of our backlog of system orders is comprised of laser spike annealing

tools. To date, we have limited experience with this technology. Should significant demand not materialize, due to technical, production, market, or other factors, our business, financial position and results of operations would be materially adversely impacted.

We rely on a limited number of outside suppliers and subcontractors to manufacture certain components and subassemblies, and on single or a limited group of outside suppliers for certain materials for our products, which could result in a potential inability to obtain an adequate supply of required components due to the suppliers’ failure or inability to provide such components in a timely manner, or at all, and reduced control over pricing and timely delivery of components and materials, any of which could adversely affect our results of operations.

Our manufacturing activities consist of assembling and testing components and subassemblies, which are then integrated into finished systems. We rely on a limited number of outside suppliers and subcontractors to manufacture certain components and subassemblies. We order one of the most critical components of our technology, the glass for our 1X lenses, from external suppliers. We design the 1X lenses and provide the lens specifications and the glass to other suppliers, who then grind and polish the lens elements. We then assemble and test the optical 1X lenses.

We procure some of our other critical systems’ components, subassemblies and services from single outside suppliers or a limited group of outside suppliers in order to ensure overall quality and timeliness of delivery. Many of these components and subassemblies have significant production lead times. To date, we have been able to obtain adequate services and supplies of components and subassemblies for our systems in a timely manner. However, disruption or termination of certain of these sources could have a significant adverse impact on our ability to manufacture our systems. This, in turn, would have a material adverse effect on our business, financial condition and results of operations. Our reliance on a sole supplier or a limited group of suppliers and our reliance on subcontractors involve several risks, including a potential inability to obtain an adequate supply of required components due to the suppliers’ failure or inability to provide such components in a timely manner, or at all, and reduced control over pricing and timely delivery of components. Although the timeliness, yield and quality of deliveries to date from our subcontractors have been acceptable, manufacture of certain of these components and subassemblies is an extremely complex process, and long lead-times are required. Any inability to obtain adequate deliveries or any other circumstance that would require us to seek alternative sources of supply or to manufacture such components internally could delay our ability to ship our products, which could damage relationships with current and prospective customers and have a material adverse effect on our business, financial condition and results of operations.

The semiconductor industry historically has been highly cyclical and has experienced periods of oversupply, which has in turn affected the market for semiconductor equipment such as ours and which can adversely affect our results of operations during such periods.

Our business depends in significant part upon capital expenditures by manufacturers of semiconductors, advanced packaging semiconductors and nanotechnology components, including thin film head magnetic recording devices, which in turn depend upon the current and anticipated market demand for such devices and products utilizing such devices. The semiconductor industry historically has been highly cyclical and has experienced recurring periods of oversupply. This has, from time to time, resulted in significantly reduced demand for capital equipment including the systems manufactured and marketed by us. We believe that markets for new generations of semiconductors and semiconductor packaging will also be subject to similar fluctuations. Our business and operating results would be materially adversely affected by downturns or slowdowns in the semiconductor packaging market or by loss of market share. Accordingly, we may not be able to achieve or maintain our current or prior level of sales. We attempt to mitigate the risk of cyclicality by participating in multiple markets including semiconductor, semiconductor packaging, and nanotechnology sectors, as well as diversifying into new markets such as laser-based

annealing for implant activation and other applications. Despite such efforts, when one or more of such markets experiences a downturn or a situation of excess capacity, our net sales and operating results are materially adversely affected.

Our industry is subject to rapid technological change and product innovation, which could result in our technologies and products being replaced by those of our competitors, which would adversely affect our business and results of operations.

The semiconductor and nanotechnology manufacturing industries are subject to rapid technological change and new product introductions and enhancements. Our ability to be competitive in these and other markets will depend, in part, upon our ability to develop new and enhanced systems and related software tools, and to introduce these systems and related software tools at competitive prices and on a timely and cost-effective basis to enable customers to integrate them into their operations either prior to or as they begin volume product manufacturing. We will also be required to enhance the performance of our existing systems and related software tools. Our success in developing new and enhanced systems and related software tools depends upon a variety of factors, including product selection, timely and efficient completion of product design, timely and efficient implementation of manufacturing and assembly processes, product performance in the field and effective sales and marketing. Because new product development commitments must be made well in advance of sales, new product decisions must anticipate both future demand and the technology that will be available to meet that demand. We may not be successful in selecting, developing, manufacturing or marketing new products and related software tools or enhancing our existing products and related software tools. Any such failure would materially adversely affect our business, financial condition and results of operations.

Because of the large number of components in our systems, significant delays can occur between a system’s introduction and our commencement of volume production of such systems. We have experienced delays from time to time in the introduction of, and technical and manufacturing difficulties with, certain of our systems and enhancements and related software features and options, and may experience delays and technical and manufacturing difficulties in future introductions or volume production of new systems or enhancements and related software features and options.

We may encounter additional technical, manufacturing or other difficulties that could further delay future introductions or volume production of systems or enhancements. Our inability to complete the development or meet the technical specifications of any of our systems or enhancements and related software tools, or our inability to manufacture and ship these systems or enhancements and related software tools in volume and in time to meet the requirements for manufacturing the future generation of semiconductor or nanotechnology devices would materially adversely affect our business, financial condition and results of operations. In addition, we may incur substantial unanticipated costs to ensure the functionality and reliability of our products early in the products’ life cycles. If new products have reliability or quality problems, reduced orders or higher manufacturing costs, delays in customer acceptance, revenue recognition and collecting accounts receivable and additional service and warranty expenses may result. Any of such events may materially adversely affect our business, financial condition and results of operations.

A substantial portion of our sales are outside of the United States, which subjects us to risks related to customer service, installation, foreign economic and political stability, uncertain regulatory and tax rules, and foreign exchange rate fluctuations, all of which make it more difficult to operate our business.

International sales accounted for approximately 69%, 65% and 61% of total net sales for the years 2005, 2004 and 2003, respectively. We anticipate that international sales, which typically have lower gross margins than domestic sales, principally due to increased competition and higher field service and support costs, will continue to account for a significant portion of total net sales. As a result, a significant portion of our net sales will continue to be subject to certain risks, including unexpected changes in regulatory

requirements; difficulty in satisfying existing regulatory requirements; exchange rate fluctuations; tariffs and other barriers; political and economic instability; difficulties in accounts receivable collections; natural disasters; difficulties in staffing and managing foreign subsidiary and branch operations; and potentially adverse tax consequences.

Although we generally transact our international sales in U.S. dollars, international sales expose us to a number of additional risk factors, including fluctuations in the value of local currencies relative to the U.S. dollar, which, in turn, impact the relative cost of ownership of our products and may further impact the purchasing ability of our international customers. However, in Japan, we have direct sales operations and orders are often denominated in Japanese yen. This may subject us to a higher degree of risk from currency fluctuations. We attempt to mitigate this exposure through the use of foreign currency forward exchange contracts. We are also subject to the risks associated with the imposition of legislation and regulations relating to the import or export of semiconductors and nanotechnology products. We cannot predict whether the United States or any other country will implement changes to quotas, duties, taxes or other charges or restrictions upon the importation or exportation of our products. These factors, or the adoption of restrictive policies, may have a material adverse effect on our business, financial condition and results of operations.

We are dependent on our key personnel, especially Mr. Zafiropoulo our Chief Executive Officer, and our business and results of operations would be adversely affected if we were to lose our key employees.

Our future operating results depend, in significant part, upon the continued contributions of key personnel, many of whom would be difficult to replace. We have entered into employment agreements with only a limited number of our employees, including our Chief Executive Officer, President, Chief Financial Officer and Senior Vice President World-wide Sales and Customer Operations, and our employees are employed “at will.” Some of these agreements contain vesting acceleration and severance payment provisions that could result in significant costs or charges to us should the employee be terminated without cause, die or have a disability. We do not maintain any life insurance on any of our key people. The loss of key personnel could have a material adverse effect on our business, financial condition and results of operations. In addition, our future operating results depend in significant part upon our ability to attract and retain other qualified management, manufacturing, technical, sales and support personnel for our operations. There are only a limited number of persons with the requisite skills to serve in these positions and it may become increasingly difficult for us to hire such personnel over time. At times, competition for such personnel has been intense, particularly in the San Francisco Bay Area where we maintain our headquarters and principal operations, and there can be no assurance that we will be successful in attracting or retaining such personnel. The failure to attract or retain such persons would materially adversely affect our business, financial condition and results of operations.

Changes in financial accounting standards or policies in the past have affected, and in the future may, affect, our reported results of operations.

We prepare our financial statements in conformity with accounting principles generally accepted in the United States, or U.S. GAAP. These principles are subject to interpretation by the Financial Accounting Standards Board (FASB), the American Institute of Certified Public Accountants (AICPA), the Securities and Exchange Commission (SEC) and various bodies formed to interpret and create appropriate accounting policies. A change in those policies can have a significant effect on our reported results and may affect our reporting of transactions completed before a change is announced.

Accounting policies affecting many other aspects of our business, including rules relating to revenue recognition, off-balance sheet transactions, employee stock options, restructurings, asset disposals and asset retirement obligations, intangible assets, derivative and other financial instruments, and in-process research and development charges, have recently been revised or are under review. Changes to those rules or the questioning of how we interpret or implement those rules may have a material adverse effect on our reported financial results or on the way we conduct business. In addition, our preparation of financial statements in accordance with U.S. GAAP requires that we make estimates and assumptions that affect the recorded amounts of assets and liabilities, disclosure of those assets and liabilities at the date of the financial statements and the recorded amounts of expenses during the reporting period. A change in the facts and circumstances surrounding those estimates could result in a change to our estimates and could impact our future operating results.

Changes in securities laws and listing standards, in particular those that have resulted from the passage of the Sarbanes-Oxley Act of 2002 and related rules and regulations, have increased our legal and financial costs, and we expect to continue to spend significant resources to comply with these requirements.

The Sarbanes-Oxley Act of 2002 required changes in our corporate governance, public disclosure and compliance practices. The number of rules and regulations applicable to us have increased and will continue to increase our legal and financial compliance costs, and have made some activities more difficult, such as by requiring stockholder approval of new option plans. In addition, we have incurred and expect to continue to incur significant costs in connection with compliance with Section 404 of the Sarbanes-Oxley Act regarding internal controls over financial reporting. We incurred significant costs to achieve initial compliance with Section 404, and we expect ongoing annual costs to maintain compliance to also be substantial. We also expect these developments to make it more difficult and more expensive to obtain director and officer liability insurance, and we may be required to accept reduced coverage or incur substantially higher costs to obtain coverage. These developments could make it more difficult for us to attract and retain qualified members of our board of directors, particularly to serve on our audit committee, and qualified executive officers. In addition, in connection with our Section 404 certification process, we may identify from time to time deficiencies in our internal controls. Any material weakness or deficiency in our internal controls over financial reporting could materially and negatively impact our reported financial results and the market price of our stock could significantly decline. Additionally, adverse publicity related to the disclosure of a material weakness or deficiency in internal controls over financial reporting could have a negative impact on our reputation, business and stock price.

Our shareholder rights plan, equity incentive plans, certain provisions of our Certificate of Incorporation and Bylaws, and Delaware law may discourage third parties from pursuing a change of control transaction with us.

Certain provisions of our Certificate of Incorporation, equity incentive plans, Shareholder Rights Plan, licensing agreements, Bylaws and Delaware law may discourage certain transactions involving a change in control of our company. In addition to the foregoing, our classified board of directors, the shareholdings of Ultratech’s officers, directors and persons or entities that may be deemed affiliates and the ability of the Board of Directors to issue “blank check” preferred stock without further stockholder approval could have the effect of delaying, deferring or preventing us from experiencing a change in control and may adversely affect the voting and other rights of holders of our Common Stock.

Our stock price has experienced significant volatility in the past and we expect this to continue in the future as a result of many factors, some of which could be unrelated to our operating performance, and such volatility can have a major impact on the number of shares subject to outstanding stock options that are included in calculating our earnings per share.

We believe that factors such as announcements of developments related to our business, fluctuations in our operating results, a shortfall in revenue or earnings, changes in analysts’ expectations, general conditions in the semiconductor and nanotechnology industries or the worldwide or regional economies, sales of our securities into the marketplace, an outbreak or escalation of hostilities, announcements of technological innovations or new products or enhancements by us or our competitors, developments in patents or other intellectual property rights and developments in our relationships with our customers and suppliers could cause the price of our Common Stock to fluctuate, perhaps substantially. The market price of our Common Stock has fluctuated significantly in the past and we expect it to continue to experience significant fluctuations in the future, including fluctuations that may be unrelated to our performance.

As of March 1, 2006, we had approximately 6,268,866 million stock options outstanding. Among other determinants, the market price of our stock has a major bearing on the number of stock options outstanding that are included in the weighted-average shares used in determining our net income (loss) per share. During periods of extreme volatility, the impact of higher stock prices can have a materially dilutive effect on our net income (loss) per share. Additionally, options are excluded from the calculation of net income (loss) per share when we have a net loss or when the exercise price of the stock option is greater than the average market price of our Common Stock, as the impact of the stock options would be anti-dilutive.

Our results of operations and business could be adversely affected by wars and other military action, as well as terrorist attacks and threats and government responses thereto, especially if any such actions were directed at us or our facilities or customers.

Terrorist attacks in the United States and elsewhere, government responses thereto, and military actions in Iraq, Afghanistan and elsewhere, may disrupt our operations or those of our customers and suppliers and may affect the availability of materials needed to manufacture our products or the means to transport those materials to manufacturing facilities and finished products to customers. In addition, any of these events could increase volatility in the United States and world financial markets which may depress the price of our Common Stock and may limit the capital resources available to us or our customers or suppliers, which could result in decreased orders from customers, less favorable financing terms from suppliers, and scarcity or increased costs of materials and components of our products. Additionally, terrorist attacks directly upon us may significantly disrupt our ability to conduct our business. Any of these occurrences could have a significant impact on our operating results, revenues and costs and may result in increased volatility of the market price of our Common Stock.

OVERVIEW

Ultratech, Inc. develops, manufactures and markets photolithography and laser thermal processing equipment for manufacturers of integrated circuits and nanotechnology components located throughout North America, Europe, Japan, Taiwan and the rest of Asia.

We supply step-and-repeat photolithography systems based on one-to-one imaging technology. Within the integrated circuit industry, we target the market for advanced packaging applications. Within the nanotechnology industry, our target markets include thin film head magnetic recording devices, optical networking devices, laser diodes and LEDs (light emitting diodes). Our laser thermal processing equipment is targeted at advanced annealing applications within the semiconductor industry.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

The discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with accounting principles

generally accepted in the United States. The preparation of these consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities at the date of the consolidated financial statements. By their nature, these estimates and judgments are subject to an inherent degree of uncertainty. On an on-going basis, we evaluate our estimates, including those related to inventories, warranty obligations, purchase order commitments, bad debts, income taxes, intangible assets, restructuring and contingencies and litigation. Management bases its estimates and judgments on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

We believe the following critical accounting policies are affected by our more significant judgments and estimates used in the preparation of our consolidated financial statements. We have reviewed these policies with our Audit Committee.

Revenue Recognition

We recognize revenue when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the seller’s price is fixed or determinable, and collectibility is reasonably assured. We derive revenue from four sources—system sales, spare parts sales, service contracts and license fees.

Provided all other criteria are met, we recognize revenues on system sales when we have received customer acceptance of the system and have completed the system installation obligations or are otherwise released from our installation obligations. In the event that terms of the sale provide for a lapsing customer acceptance period, we recognize revenue upon the expiration of the lapsing acceptance period or customer acceptance, whichever occurs first. In these instances, revenue is recorded only if the product has met product specifications prior to shipment and management deems that no significant uncertainties as to product performance exist.

Our transactions frequently include the sale of systems and services under multiple element arrangements. In situations with multiple deliverables, revenue is recognized upon the delivery of the separate elements and when we receive customer acceptance or are otherwise released from our customer acceptance obligations. Consideration from multiple element arrangements is allocated among the separate accounting units based on the residual method under which the revenue is allocated to undelivered elements based on fair value of such undelivered elements and the residual amounts of revenue allocated to delivered elements, provided the undelivered elements have value on a stand alone basis, there is objective and reliable evidence of fair value for the undelivered elements, the arrangement does not include a general right of return relative to the delivered item and delivery or performance of the undelivered item(s) is considered probable and substantially in our control. The maximum revenue recognized on a delivered element is limited to the amount that is not contingent upon the delivery of additional items.

We generally recognize revenue from spare parts sales upon shipment, as our products are generally sold on terms that transfer title and risk of ownership when it leaves our site. We sell service contracts for which revenue is deferred and recognized ratably over the contract period and service contracts based on a purchased quantity of hours under which revenue is recognized as service hours are delivered. We recognize revenue from licensing and technology support agreements ratably over the contract period, or the estimated useful life of the licensed technologies, whichever is shorter.

Costs related to deferred product revenues are capitalized (deferred) and recognized at the time of revenue recognition. Deferred product revenue and costs are netted on our balance sheet, under the caption “deferred product and services income.”

Inventories and Purchase Order Commitments

The semiconductor industry is characterized by rapid technological change, changes in customer requirements and evolving industry standards. We perform a detailed assessment of inventory at each balance sheet date, which includes a review of, among other factors, demand requirements and market conditions. Based on this analysis, we record adjustments, when appropriate, to reflect inventory at lower of cost or market. Although we make every effort to ensure the accuracy of our forecasts of product demand, any significant unanticipated changes in demand, product mix or technological developments would significantly impact the value of our inventory and our reported operating results. In the future, if we find that our estimates are too optimistic and we determine that our inventory needs to be written down, we will be required to recognize such costs in our cost of sales at the time of such determination. For example, if the demand assumption used in our assessment at December 31, 2005 was reduced by 10%, assuming all other assumptions such as product mix are kept the same and that mitigation efforts were not possible, we would have had to write down our inventory and open purchase commitments by $48,000. Conversely, if we find our estimates are too pessimistic and we subsequently sell product that has previously been written down, our gross margin in that period will be favorably impacted. During 2002, we recorded a write down of inventory of $6.7 million and subsequently we realized favorable gross margin impacts of $0.1 million, $1.0 million and $1.7 million, respectively, in 2005, 2004 and 2003 due to sales of inventory that was previously written down.

Warranty Obligations

We recognize the estimated cost of our product warranties at the time revenue is recognized. Our warranty obligation is affected by product failure rates, material usage rates and the efficiency by which the product failure is corrected. Should actual product failure rates, material usage rates and labor efficiencies differ from our estimates, revisions to the estimated warranty liability would be required which could result in future charges or credits to our gross margins. During the three years ended December 31, 2005, our estimates and assumptions have not changed significantly and our estimates have approximated actual costs incurred. In 2005, the Company commenced volume shipments of its unity-based lithography systems. As may occur with new product introductions, after-sales (warranty) costs were higher than anticipated. The Company believes its warranty accrual, as of December 31, 2005, will be sufficient to satisfy outstanding obligations as of that date.

Allowance for Bad Debt

We maintain an allowance for estimated losses resulting from the inability of our customers to make required payments. This reserve is established based upon historical trends, current economic conditions, delinquency status based on contractual terms and an analysis of specific exposures. If the financial condition of our customers were to deteriorate, or even a single customer was otherwise unable to make payments, additional allowances may be required. The average selling price of our systems is in excess of $2.0 million. Accordingly, a single customer default could have a material adverse effect on our results of operations. Our bad debt reserve as a percentage of gross accounts receivable increased from 1.5% at December 31, 2003 to 2.9% at December 31, 2005 due to the impact of bad debt expense associated with a customer bankruptcy filing ($0.3 million) during 2005.

Deferred Income Taxes

We record a valuation allowance to reduce our deferred tax assets to the amount that is more likely than not to be realized. As of December 31, 2005, we had recorded a valuation allowance of $74.0 million to fully reserve our U.S. net deferred tax assets. As of December 31, 2005, we had recorded approximately $0.3 million of foreign deferred tax assets related to our Japanese operations. Based on projected future pre-tax income in Japan, these assets were not subject to a valuation allowance as it is more likely than not that they will be realized in the future.

RESULTS OF OPERATIONS

We derive a substantial portion of our total net sales from sales of a relatively small number of newly manufactured systems, which typically range in price from $1.2 million to $4.5 million. As a result of these high sale prices, the timing and recognition of revenue from a single transaction has had and most likely will continue to have a significant impact on our net sales and operating results for any particular period.

Our backlog at the beginning of a period typically does not include all of the sales needed to achieve our sales objectives for that period. In addition, orders in backlog are subject to cancellation, shipment or customer acceptance delays, and deferral or rescheduling by a customer with limited or no penalties. Consequently, our net sales and operating results for a period have been and will continue to be dependent upon our obtaining orders for systems to be shipped and accepted in the same period in which the order is received. Our business and financial results for a particular period could be materially adversely affected if an anticipated order for even one system is not received in time to permit shipment and customer acceptance during that period. Furthermore, a substantial portion of our shipments have historically occurred near the end of each quarter. Delays in installation and customer acceptance due, for example, to our inability to successfully demonstrate the agreed-upon specifications or criteria at the customer’s facility, or to the failure of the customer to permit installation of the system in the agreed upon time, may cause net sales in a particular period to fall significantly below our expectations, which may materially adversely affect our operating results for that period. This risk is especially applicable in connection with the introduction and initial sales of a new product line. Additionally, the failure to receive anticipated orders or delays in shipments due, for example, to rescheduling, delays, deferrals or cancellations by customers, additional customer configuration requirements, or to unexpected manufacturing difficulties or delays in deliveries by suppliers due to their long production lead times or otherwise, have caused and may continue to cause net sales in a particular period to fall significantly below our expectations, materially adversely affecting our operating results for that period. In particular, the long manufacturing and acceptance cycles of our advanced packaging family of wafer steppers and laser thermal processing systems and the long lead time for lenses and other materials, could cause shipments and acceptances of such products to be delayed from one quarter to the next, which could materially adversely affect our financial condition and results of operations for a particular quarter.

Additionally, the need for continued expenditures for research and development, capital equipment, ongoing training and worldwide customer service and support, among other factors, will make it difficult for us to reduce our operating expenses in a particular period if we fail to achieve our net sales goals for the period.

Net sales

2005 vs. 2004

					Amount of				Percentage
(in millions)	2005		2004		Change				change
Sales of:
Systems	$	93.2	$	82.0		$	11.2			14	%
Spare parts	15.2		11.4			3.8				33	%
Services	12.5		12.3			0.2				2	%
Licenses	1.5		4.2			(2.7		)		-64	%
Total Net Sales	$	122.4	$	109.9		$	12.5			11	%

Net sales consist of revenues from system sales, spare parts sales, services and licensing of technologies. System sales increased 14%, to $93.2 million. The average selling price of systems sold increased 29% from the prior year primarily as a result of increased sales to laser thermal processing and advanced packaging customers. The number of systems sold declined by 12% as a result of decreased sales of the Company’s 1000 and 100 series products. In 2005, refurbished systems accounted for approximately 18% of units sold as compared to 30% of units sold in 2004. This percentage can fluctuate from year to year and, as refurbished units generally have lower average selling prices than new units, any such fluctuation will impact the weighted average selling price of the systems sold.

On a product market application basis, system sales to the semiconductor industry were $ 73.4 million for the year ended December 31, 2005, an increase of 19% as compared with system sales of $61.5 million in 2004. This increase was due to an 18% increase in sales to the advanced packaging markets and a 217% increase in laser thermal processing system sales. These systems typically have significantly higher average selling prices, as compared to the Company’s nanotechnology offerings. System sales to the nanotechnology market were $19.8 million for the year ended December 31, 2005, a decrease of 3% as compared with sales of $20.5 million in 2004.

Sales of spare parts for 2005 increased 33%, to $15.2 million, as compared to 11.4 million in 2004. This increase was mainly due to more revenue from system upgrades in 2005 as compared to 2004. Revenues from services grew 2% to $12.5 million for the year ended December 31, 2005 as compared with $12.3 million in 2004.

Revenues from licensing and licensing support arrangements declined to $1.5 million, as compared with $4.2 million in 2004, as a result of the completion of the amortization period of prior-period proceeds from licensing agreements. Future revenues from licensing activities, if any, will be contingent upon existing and future licensing and royalty arrangements, including those, if any, resulting from litigation. The Company may not be successful in generating licensing revenues in the future.

At December 31, 2005, we had approximately $2.0 million of deferred product and services income resulting from products shipped but not yet installed and accepted and deferred service revenue, as compared with $1.2 million at December 31, 2004.

For the year ended December 31, 2005, international net sales were $84.9 million, or 69% of total net sales, as compared with $71.7 million, or 65% of total net sales for 2004. We expect sales to international customers to continue to represent a significant majority of our revenues during 2006. Our revenue derived from sales in foreign countries is not generally subject to significant exchange rate fluctuations, principally because sales contracts for our systems are generally denominated in U.S. dollars. In Japan, however, orders are often denominated in Japanese yen. For the year ended December 31, 2005, we recorded system sales in Japan of $12.5 million, of which 26% were denominated in Japanese yen. This subjects us to the risk of currency fluctuations. We attempt to mitigate this risk by entering into foreign currency forward

exchange contracts for the period between when an order is received and when it is recorded as revenue. After recording revenue, we use various mechanisms, such as foreign currency forward exchange contracts and natural hedges, to offset substantial portions of the gains or losses associated with our Japanese yen denominated receivables due to exchange rate fluctuations. We had approximately $1.6 million of Japanese yen-denominated receivables at December 31, 2005. International sales expose us to a number of additional risks, including fluctuations in the value of local currencies relative to the U.S. dollar, which impact the relative cost of ownership of our products and, thus, the customer’s willingness to purchase our product. (See “Risk Factors: International Sales”).

2004 vs. 2003

(millions)	2004		2003		Amount of Change				Percentage change
Sales of:
Systems	$	82.0	$	73.6		$	8.4			11	%
Spare parts	11.4		12.3			(0.9		)		(7	)%
Services	12.3		10.6			1.7				16	%
Licenses	4.2		3.7			0.5				14	%
Total Net Sales	$	109.9	$	100.1		$	9.8			10	%

System sales in 2004 increased 11%, to $82.0 million, on a unit volume increase of 14% as compared to 2003. The weighted-average selling prices of systems sold declined 2% from 2003 due to an increase in the percentage of refurbished systems sold as compared to 2003. In 2004, refurbished systems accounted for approximately 30% of units sold as compared to 22% of units sold in 2003.

On a product market application basis, system sales to the semiconductor industry, primarily for advanced packaging applications, were $61.5 million for the year ended December 31, 2004, an increase of 11% as compared with system sales of $55.4 million in 2003. This increase was due to a 7% increase in volume and a 4% increase in the weighted average selling price resulting from a small decrease in the percentage of refurbished systems sold in 2004 as compared to 2003. System sales to the nanotechnology market were $20.5 million for the year ended December 31, 2004, an increase of 13% as compared with sales of $18.1 million in 2003. This increase was due to a 27% increase in volume, primarily as a result of increased sales to thin film head customers, partially offset by a decrease in the weighted average selling price. The decrease in the weighted average selling price resulted from an increase in the percentage of refurbished systems sold in 2004 as compared to 2003. In 2004, refurbished systems accounted for approximately 42% of units sold as compared to 27% of units sold in 2003.

Sales of spare parts for 2004 decreased 7%, to $11.4 million, as compared to 2003. This decrease was due to less revenue from system upgrades and a lower level of spare parts sales activity in Asia. Revenues from services increased 16%, to $12.3 million, primarily as a result of an increase in system relocations and new service contracts for existing customers in North America and Asia.

Revenues from licensing and licensing support arrangements increased to $4.2 million in 2004, as compared with $3.7 million in 2003, as a result of a payment we received from a company under a licensing agreement.

At December 31, 2004, we had approximately $1.2 million of deferred product and services income resulting from products shipped but not yet installed and accepted and deferred service revenue, essentially the same level as reported at December 31, 2003. During 2004, deferred license revenue decreased by $3.7 million, to $1.0 million, as a result of amortization of proceeds received in prior periods. Amortization of deferred license income results in current period license revenue. Deferred income

related to our products is recognized upon satisfying the contractual obligations for installation and/or customer acceptance.

For the year ended December 31, 2004, international net sales were $ 71.7 million, or 65 % of total net sales, as compared with $61.4 million, or 61% of total net sales for 2003.

Gross profit

2005 vs. 2004

On a comparative basis, gross margins were 42.5% and 47.9% for 2005 and 2004, respectively. The 5.4 percentage point decline in gross margin in 2005 was due to changes in revenue mix resulting primarily from the three laser thermal processing systems accepted during the fourth quarter of 2005 (2.5 points), certain manufacturing costs (1.3 points) and installation costs (0.9 points) resulting from the production and shipment ramp of our laser thermal processing systems and unity platform lithography systems and higher manufacturing costs resulting from facilities upgrades completed in late 2004 (0.7 points).

Exclusive of licensing revenues, gross margin was 41.8% for 2005 as compared with 45.9% for 2004. We believe disclosure of gross margins without reference to licensing revenues provides additional appropriate disclosure to allow comparison of our product and service gross margins over time because there is little, if any, cost of sales associated with our licensing revenues.

Our gross profit as a percentage of sales has been and most likely will continue to be significantly affected by a variety of factors, including the mix of products sold; the introduction of new products, which typically have higher manufacturing, installation and after-sale support costs until efficiencies are realized and which are typically discounted more than existing products until the products gain market acceptance; the rate of capacity utilization; writedowns of inventory and open purchase commitments; technology support and licensing revenues, which have no associated cost of sales; product discounts, pricing and competition in our targeted markets; non-linearity of shipments during the quarter which can result in manufacturing inefficiencies; the percentage of international sales, which typically have lower gross margins than domestic sales principally due to higher field service and support costs; and start-up costs and inefficiencies associated with the implementation of subcontracting arrangements.

2004 vs. 2003

On a comparative basis, gross margins were 47.9% and 46.6% for 2004 and 2003, respectively. The 1.3 percentage point improvement in gross margin in 2004 was due primarily to costs associated with increased production and services activity (2.1 points) and increased license revenue which has little, if any, cost of sales associated with it (.5 points) offset partially by the favorable impact in 2003 from the sale of 3 XLS reduction lithography systems which had been previously written down (0.7 percentage points) and the favorable impact in 2003 due primarily to the sale of inventory previously written down (0.6 percentage points).

Exclusive of licensing revenues, gross margin was 45.9% for 2004 as compared with 44.5% for 2003. We believe disclosure of gross margins without reference to licensing revenues provides additional appropriate disclosure to allow comparison of our product and service gross margins over time because there is little, if any, cost of sales associated with our licensing revenues.

Research, development and engineering expenses

2005 vs. 2004

					Amount of			Percentage
(in millions)	2005		2004		Change			change
Research, development and engineering expenses	$	27.0	$	25.9		$	1.1		4	%

The increase in research, development and engineering expenses in 2005, as compared to 2004, was primarily due to increased investments in the development of our laser processing technologies during the first half of 2005. We continue to invest significant resources in the development and enhancement of our laser processing systems and technologies and our 1X products and related technologies. In 2005, the Company revenued three laser thermal processing systems which was the result of our 2005 research, development and engineering effort. Given that there is an inherent delay between the time product development activities and expenditures occur and when resultant product revenue is ultimately realized, current year research, development and engineering investments contributed will continue to contribute to revenue in future years.

2004 vs. 2003

					Amount of			Percentage
(in millions)	2004		2003		Change			change
Research, development and engineering expenses	$	25.9	$	21.3		$	4.6		22	%

The increase in research, development and engineering expenses in 2004, as compared to 2003, was due to increased investments in the development of our laser processing technologies and our next generation 1X stepper products.

Amortization of intangible assets

Amortization of intangible assets was $0.1 million, $0.4 million and $0.4 million for the years ended December 31, 2005, 2004 and 2003, respectively. Intangible assets consist of royalties received from prior-period proceeds from licensing agreements. It was fully amortized during the year ended December 31, 2005.

Selling, general and administrative expenses

2005 vs. 2004

					Amount of			Percentage
(in millions)	2005		2004		Change			change
Selling, general and administrative expenses	$	29.9	$	28.8		$	1.1		4	%

Selling, general and administrative expenses increased by $1.1 million, or 4%, in 2005, as compared to 2004. This increase was due to an increase in legal costs, primarily related to our being a plaintiff in several patent infringement lawsuits ($2.1million), partially offset by decreased selling expenses in North America ($0.5 million) and lower sales commission expenses ($0.5 million).

2004 vs. 2003

(in millions)	2004		2003		Amount of Change			Percentage change
Selling, general and administrative expenses	$	28.8	$	22.7		$	6.1		27	%

The year-over-year increase in selling, general and administrative expense was $6.1 million. This increase was due to increased marketing and sales activity primarily driven by our efforts in laser processing ($2.2 million), increased legal costs primarily related to our being a plaintiff in a patent infringement lawsuit ($1.3 million), increased costs associated with our compliance with the Sarbanes-Oxley Act of 2002 and related SEC and Nasdaq rules ($0.5 million), increased sales commission expense due to increased revenues ($0.5 million), and other individually insignificant items which in total increased $1.6 million.

Interest and other income, net

	Years Ended December 31,
(in thousands)	2005			2004			2003
Interest income	$	4,752		$	3,624		$	4,338
Other income (expense), net	(19		)	(12		)	(61		)
Interest and other income, net	$	4,733		$	3,612		$	4,277

Interest income was $4.8 million for the year ended December 31, 2005, as compared with $3.6 million for 2004. The increase in 2005 from 2004 was primarily due to higher interest rates on our investments.

Included in the amount reported for 2003 was $0.3 million, relating to interest on tax settlements or refunds. The decrease in 2004 from 2003, excluding the interest income on tax settlements or refunds, was primarily due to lower interest rates on our investments.

We presently maintain an investment portfolio with a weighted-average maturity of less than two years. Consequently, changes in short-term interest rates have a significant impact on our interest income. Future changes are expected to have a similar impact.

Provision (benefit) for income taxes

For the year ended December 31, 2005, we recorded an income tax expense of $0.7 million, comprised primarily of foreign taxes. The actual expense recorded differs from the federal tax benefit at 35% primarily due to current tax expense in foreign jurisdictions and the fact that the tax benefit of U.S. losses is not recognized.

For the year ended December 31, 2004, we recorded an income tax expense of $0.4 million which included a $0.1 million benefit related to the settlement of tax audit issues in the United Kingdom. The actual expense recorded, excluding the benefit related to the settlement of tax audit issues in the United Kingdom, represents 51% of pre-tax income. This rate is higher than the U.S. federal rate of 35% because the tax benefit of U.S. losses was not recognized as domestic deferred tax assets are fully reserved.

For the year ended December 31, 2003, we recorded an income tax benefit of $0.6 million, inclusive of a special tax benefit of $0.4 million related to the settlement of a research and development tax credit claim with the California Franchise Tax Board and $0.4 million related to the resolution of certain tax audit issues in the United Kingdom. Additionally, we recorded a $0.5 million benefit from the reversal of reserves associated with deferred tax assets carried on the balance sheet of our Japan subsidiary, reflecting improved operating trends in that region. Offsetting these tax benefits was a tax expense of approximately $0.7 million related, primarily, to taxable income in our foreign entities, for which there is no corresponding net operating loss carry-forward benefit.

In October 2004, the United States enacted The American Jobs Creation Act of 2004 (“the Act”). The Act provides for a three year phase-out of current extraterritorial income tax (“ETI”) benefits and replaces ETI with a phased-in nine percent domestic production activity deduction that will not be fully effective until 2010. We do not currently realize ETI tax benefits. This provision of the Act is not expected to have a material effect on our results of operations or financial position in the near future. The Act also includes a temporary deduction of 85% for certain foreign earnings that are repatriated, as defined in the Act. We did not repatriate any of our foreign earnings during the effective period of this deduction under the Act.

Income taxes can be affected by estimates of whether, and within which jurisdictions, future earnings will occur and how and when cash is repatriated to the United States, combined with other aspects of an overall income tax strategy. Additionally, taxing jurisdictions could retroactively disagree with our tax treatment of certain items, and some historical transactions have income tax effects going forward. Accounting rules require these future effects to be evaluated using current laws, rules and regulations, each of which can change at any time and in an unpredictable manner. We believe we have adequately

provided for any reasonably foreseeable outcome related to these matters, and we do not anticipate any material earnings impact from their ultimate resolutions.

Cumulative effect of the adoption of FIN 47

In December 2005 we adopted FASB Interpretation No. 47, “Accounting for Contingent Asset Retirement Obligations” (“FIN 47”), an interpretation of FASB Statement No. 143, “Asset Retirement Obligations” (“SFAS 143”). FIN 47 clarifies that the term “conditional asset retirement obligation” as used in SFAS 143 refers to a legal obligation to perform an asset retirement activity in which the timing and (or) method of settlement are conditional on a future event that may or may not be within the control of the entity. An entity is required to recognize a liability for the fair value of a conditional asset retirement obligation if the fair value of the liability can be reasonably estimated, even if conditional on a future event. As permitted, we recognized the effect of applying FIN 47 as a cumulative effect of a change in accounting principle. Our adoption of FIN 47 resulted in an increase in net equipment and leasehold improvements of approximately $1.0 million, recognition of an asset retirement obligation (the “ARO”) liability of $2.1 million, and a cumulative effect of adoption of $1.1 million or $0.05 per share, for the year ended December 31, 2005. The ARO liability is principally for estimable asset retirement obligations related to remediation costs, which we estimate will be incurred upon the expiration of certain operating leases.

Outlook

Although we believe that our served markets have generally strengthened during the last twelve months, the anticipated timing of orders, shipments and customer acceptances usually requires us to fill a number of production slots in any given quarter in order to meet our sales targets. If we are unsuccessful in our efforts to secure those production orders, or if existing production orders are delayed or cancelled, our results of operations will be materially adversely impacted. Accordingly, we may not be able to achieve or maintain our current or prior level of sales. We presently expect that net sales for 2006 will increase 10% to 20% from the level of net sales reported in 2005 of $122.4 million.

Because our net sales are subject to a number of risks, including risks associated with the introduction of our new laser processing product line, delays in customer acceptance, intense competition in the capital equipment industry, uncertainty relating to the timing and market acceptance of our products, and the condition of the macro-economy and the semiconductor industry, we may not exceed or maintain our current or prior level of net sales for any period in the future. Additionally, we believe that the market acceptance and volume production of our advanced packaging systems, laser processing systems, and our 1000 series family of wafer steppers are of critical importance to our future financial results. At December 31, 2005, these critical systems represented 90% of our backlog. To the extent that these products do not achieve or maintain significant sales due to difficulties involving manufacturing or engineering, the inability to reduce the current long manufacturing cycles for these products, competition, excess capacity in the semiconductor or nanotechnology device industries, or any other reason, our business, financial condition and results of operations would be materially adversely affected.

We believe that gross margin for 2006 will be between 45% and 46%, as compared to gross margin of 43% for 2005. The final gross margin achieved will depend heavily upon sales volumes and the resulting product mix. Should our sales not reach the level expected, we may incur a higher risk of inventory obsolescence and excess purchase commitments and lower utilization of our manufacturing infrastructure, which would materially adversely impact our results of operations. New products generally have lower gross margins until there is widespread market acceptance and until production and after-sales efficiencies can be achieved. Should significant market demand fail to develop for our laser processing systems and our new advanced packaging offerings, our business, financial condition and results of operations would be materially adversely affected. In addition, higher costs associated with extended manufacturing and customer acceptance periods on shipments of our new laser processing products have had, and will continue to have, an adverse impact on our gross margins.

We believe operating margin for 2006 will be between 2% and 5% and net income per share will be between $0.25 and $0.45.

LIQUIDITY AND CAPITAL RESOURCES

Net cash provided by operating activities was $4.1 million for the year ended December 31, 2005, as compared with net cash used in operations of $10.5 million for the comparable period in 2004. Net cash provided by operating activities during the year ended December 31, 2005 was attributable to the non-cash charges to income for depreciation and amortization of $7.5 million, cumulative effect of the adoption of FIN47 of $1.1 million, offset partially by the net loss of $2.3 million, and a net change in operating assets and liabilities of $2.4 million. The $2.4 million use of cash from the net change in operating assets and liabilities was primarily a result of a decrease in accounts payable of $5.2 million due to investments in our facilities and inventory purchases related to our laser processing product during the fourth quarter of 2004; an increase in inventories of $1.1 million due to the increase in the number of laser thermal processing evaluation units at our customer sites; and a decrease in deferred license revenue of $1.0 million due to the completion of the amortization period of prior-period proceeds from licensing agreements. These uses were partially offset by an increase in accrued expenses of $1.6 million, due primarily to an increase in various tax liabilities of $1.5 million; a decrease in accounts receivable of $0.8 million; an increase in income tax payable of $0.7 million; an increase in deferred product and services income of $0.7 million, and an increase in other liabilities of $0.5 million, due to a $0.4 million increase in our deferred compensation liability.

We believe that because of the relatively long manufacturing cycle of certain of our systems, particularly newer products, our inventories will continue to represent a significant portion of working capital. Currently, we are devoting significant resources to the development, introduction and commercialization of our laser processing system and to the development of our next generation 1X lithography technologies. We currently intend to continue to incur significant operating expenses in the areas of research, development and engineering, manufacturing, and selling, general and administrative costs in order to further develop, produce and support these new products. Additionally, gross profit margins, inventory and capital equipment levels may be adversely impacted in the future by costs associated with the initial production of the laser processing system and by future generations of our 1X wafer steppers. These costs include, but are not limited to, additional manufacturing overhead, costs of demonstration systems and facilities and the establishment of additional after-sales support organizations. Additionally, there can be no assurance that operating expenses will not increase, relative to sales, as a result of adding technical, marketing and administrative personnel, among other costs, to support our new products. If we are unable to achieve significantly increased net sales or if our sales fall below expectations, our cash flow and operating results will be materially adversely affected until, among other factors, costs and expenses can be reduced. Our failure to achieve our sales targets for these new products could result in additional inventory write-offs and asset impairment charges, either of which could materially adversely impact our results of operations.

During the year ended December 31, 2005, net cash used in investing activities was $11.0 million due to capital expenditures of $8.6 million and a net increase in available-for-sale securities of $2.5 million. We are planning to incur capital expenditures in 2006 of approximately $5.4 million for equipment and facility improvements driven primarily by our new product introductions.

Net cash used in financing activities was $5.3 million during the year ended December 31, 2005, attributable to stock repurchases of $9.2 million, net repayment of notes payable of $3.6 million, offset by $7.5 million in proceeds received from the issuance of Common Stock under our employee stock option plans.

At December 31, 2005, we had working capital of $165.2 million. Our principal source of liquidity at December 31, 2005 consisted of $136.8 million in cash, cash equivalents and short-term investments, net of related borrowings under our line of credit.

We have approximately $10.9 million of retained earnings in our foreign subsidiaries. Although it is not our intent to repatriate these earnings, possible adverse tax consequences associated with repatriating these funds may effectively restrict their use to cash requirements in those specific jurisdictions.

In December 2004, we entered into a line of credit agreement with a brokerage firm replacing a similar arrangement that we had with a different firm. Under the terms of this agreement, we may borrow funds at a cost equal to the current Federal funds rate plus 100 basis points (5.25% as of December 31, 2005). Certain of our cash, cash equivalents and short-term investments secure borrowings outstanding under this facility. Funds are advanced to us under this facility based on pre-determined advance rates on the cash and securities held by us in this brokerage account. This agreement has no set expiration date and there are no loan covenants. As of December 31, 2005, $4.3 million was outstanding under this facility, with a related collateral requirement of approximately $5.7 million of our cash, cash equivalents and short-term investments. As of December 31, 2004, $7.9 million was outstanding under a similar facility, with a related collateral requirement of approximately $10.5 million of our cash, cash equivalents and short-term investments.

On September 19, 2005, the Company’s Board of Directors authorized the repurchase of up to $30 million of its common stock in the open market at then prevailing market prices during the period commencing September 19, 2005 through September 30, 2007. At December 31, 2005, the Company had repurchased 644,535 shares of its common stock at a total purchase price of $9.2 million. Future repurchases of its common stock could have a significant impact on the Company’s cash position.

The following summarizes our contractual obligations at December 31, 2005, and the effect such obligations are expected to have on our liquidity and cash flows in future periods:

			Less than									After
(in millions)	Total		1 year			1-3 years			3-5 years			5 years
Notes payable obligations	$	4.3		$	4.3		$	—		$	—		$	—
Non-cancelable operating lease obligations	22.1			4.8			9.5			7.4			0.4
Long-term payables	0.7			—			—			—			0.7
Asset retirement obligations	2.8			—			—			1.5			1.3
Open purchase order commitments	29.6			25.4			4.2			—			—
Total contractual cash obligations	$	59.5		$	34.5		$	13.7		$	8.9		$	2.4

The amounts shown in the table above for open purchase order commitments are primarily related to the purchase of inventories, equipment and leasehold improvements. We record charges to operations for purchase order commitments we deem in excess of normal operating requirements (see “Critical Accounting Policies and Estimates”).

The development and manufacture of new lithography systems and enhancements are highly capital-intensive. In order to be competitive, we believe we must continue to make significant expenditures for capital equipment; sales, service, training and support capabilities; systems, procedures and controls; and expansion of operations and research and development, among many other items. We expect that cash generated from operations and our cash, cash equivalents and short-term investments will be sufficient to meet our cash requirements for at least the next twelve months. However, in the near-term, we may continue to utilize existing and future lines of credit, and other sources of financing, in order to maintain our present levels of cash, cash equivalents and short-term investments. Beyond the next twelve months, we may require additional equity or debt financing to address our working capital or capital equipment needs. In addition, we may seek to raise equity or debt capital at any time that we deem market conditions to be favorable. Additional financing, if needed, may not be available on reasonable terms, or at all.

We may in the future pursue additional acquisitions of complementary product lines, technologies or businesses. Future acquisitions may result in potentially dilutive issuances of equity securities, the incurrence of debt and contingent liabilities and amortization expenses and impairment charges related to goodwill and other intangible assets, which could materially adversely affect our financial condition and results of operations. In addition, acquisitions involve numerous risks, including difficulties in the assimilation of the operations, technologies, personnel and products of the acquired companies; the diversion of management’s attention from other business concerns; risks of entering markets in which we have limited or no direct experience; and the potential loss of key employees of the acquired company. In the event we acquire product lines, technologies or businesses which do not complement our business, or which otherwise do not enhance our sales or operating results, we may incur substantial write-offs and higher recurring operating costs, which could have a material adverse effect on our business, financial condition and results of operations. In the event that any such acquisition does occur, there can be no assurance as to the effect thereof on our business or operating results.

Off-Balance Sheet Transactions

Our off-balance sheet transactions consist of certain financial guarantees, both expressed and implied, related to indemnification for product liability, patent infringement and latent product defects. Other than liabilities recorded pursuant to known product defects, at December 31, 2005, we did not record a liability associated with these guarantees, as we have little or no history of costs associated with such indemnification requirements.

Foreign currency

As part of our overall strategy to manage the level of exposure to the risk of foreign currency exchange rate fluctuations, we attempt to hedge most of our Japanese yen denominated foreign currency exposures. We use foreign currency forward contracts to hedge the risk that unremitted Japanese yen denominated receipts from customers for actual or forecasted sales of equipment after receipt of customer orders may be adversely affected by changes in foreign currency exchange rates. After recording revenue, we use various mechanisms, such as foreign currency forward exchange contracts and natural hedges, to offset substantial portions of the potential gains or losses associated with our Japanese yen denominated assets and liabilities due to exchange rate fluctuations. At December 31, 2005, we had taken action to hedge approximately 100% of these Japanese yen denominated exposures. In addition to natural hedges resulting from having both assets and liabilities denominated in Japanese yen, we enter into foreign currency forward contracts that generally have maturities of nine months or less. We often close foreign currency forward contracts by entering into an offsetting contract. At December 31, 2005, we had contracts for the sale of $6.5 million of foreign currencies at fixed rates of exchange.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest rate risk

Our exposure to market risk due to potential changes in interest rates, relates primarily to our investment portfolio, which consisted primarily of fixed interest rate instruments as of December 31, 2005 and 2004. We maintain an investment policy designed to ensure the safety and preservation of our invested funds by limiting market risk and the risk of default.

Certain of our cash, cash equivalents and short-term investments serve as collateral for a line of credit we maintain with a brokerage firm. The line of credit is used for liquidity purposes, mitigating the need to liquidate investments in order to meet our current operating cash requirements.

The following table presents the hypothetical changes in fair values in the financial instruments held by us at December 31, 2005 that are sensitive to changes in interest rates. These instruments are comprised of cash, cash equivalents and short-term investments. These instruments are held for purposes other than trading. The modeling techniques used measure the change in fair values arising from selected

hypothetical changes in interest rates. Assumed market value changes to our portfolio reflects immediate hypothetical parallel shifts in the yield curve of plus or minus 50 basis points (BPS), 100 BPS, and 150 BPS:

We have not materially altered our investment objectives or criteria and believe that, although the composition of our portfolio has changed from the preceding year, the portfolio’s sensitivity to changes in interest rates is materially the same.

Credit risk

We mitigate credit default risk by attempting to invest in high credit quality securities and by positioning our portfolio to respond appropriately to a significant reduction in a credit rating of any investment issuer or guarantor. The portfolio includes only marketable securities with active secondary or resale markets to ensure portfolio liquidity and is diversified in accordance with our investment policy. To date, we have not experienced significant liquidity problems with our portfolio. Our largest holding at December 31, 2005, excluding the United States government and its agencies, was $4.3 million.

Foreign exchange risk

The majority of our revenue, expense and capital purchasing activities are transacted in U.S. dollars. However, we do enter into these transactions in other currencies, primarily Japanese Yen. To protect against reductions in value and the volatility of future cash flows caused by changes in currency exchange rates we have established transaction and balance sheet hedging programs. We use foreign currency forward contracts to hedge the risk that unremitted Japanese yen denominated receipts from customers for actual or forecasted sales of equipment after receipt of customer orders may be adversely affected by changes in foreign currency exchange rates. After recording revenue, we use various mechanisms, such as foreign currency forward exchange contracts and natural hedges, to offset substantial portions of the potential gains or losses associated with our Japanese yen denominated assets and liabilities due to exchange rate fluctuations. At December 31, 2005, we had taken action to hedge approximately 100% of these Japanese yen denominated exposures. In addition to natural hedges resulting from having both assets and liabilities denominated in Japanese yen, we enter into foreign currency forward contracts that generally have maturities of nine months or less. We often close foreign currency forward contracts by entering into an offsetting contract. At December 31, 2005, we had contracts for the sale of $6.5 million of Japanese yen at fixed rates of exchange. Our hedging programs reduce, but do not always entirely eliminate, the impact of currency movements.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. COMPANY AND INDUSTRY INFORMATION

Nature of operations

Ultratech, Inc. (referred to as “Ultratech” and “we”) develops, manufactures and markets photolithography and laser thermal processing equipment for manufacturers of semiconductor and nanotechnology components located throughout North America, Europe, Japan, Taiwan and the rest of Asia.

Major customers

Intel Corporation accounted for 13%, 10% and 26% of our net sales for the years ended December 31, 2005, 2004 and 2003, respectively. Intel Corporation accounted for less than 10% of our accounts receivable at December 31, 2005.

Business segments

In evaluating its business segments, we gave consideration to the Chief Executive Officer’s review of financial information and the organizational structure of our management. Based on this review, we concluded that, at the present time, resources are allocated and other financial decisions are made based on consolidated financial information. Accordingly, we have determined that we operate in one business segment, which is the manufacture and distribution of capital equipment to manufacturers of integrated circuits and nanotechnology components.

Enterprise-wide disclosures

Our products are manufactured in the United States and are sold worldwide. We market our products internationally through domestic and foreign-based sales and service. The following table presents enterprise-wide sales to external customers and long-lived assets by geographic region:

In thousands	2005		2004		2003
Net sales:
United States of America	$	37,506	$	38,152	$	38,732
Japan	16,081		35,631		27,987
Europe	21,156		4,346		11,602
Taiwan	20,890		13,912		10,563
Rest of world	26,733		17,851		11,237
Total	$	122,366	$	109,892	$	100,121
Long-lived assets:
United States of America	$	30,494	$	27,211	$	23,017
Rest of world	1,080		1,796		948
Total	$	31,574	$	29,007	$	23,965

The rest of the world is comprised of sales to customers and long-lived assets in countries that are individually insignificant.

With the exception of Japan, our operations in foreign countries are not currently subject to significant exchange rate fluctuations, principally because sales contracts for our systems are generally denominated in U.S. dollars. In Japan, we sell our products in both U.S. dollars and Japanese yen. However, we attempt to mitigate our currency exposure through the use of currency forward contracts. (See “Derivative Instruments and Hedging” in Footnote 4)

2. CONCENTRATIONS OF RISKS

Financial instruments that potentially subject Ultratech to concentrations of credit risk consist principally of cash equivalents, short-term investments and trade receivables. These credit risks include the potential inability of an issuer or customer to honor their obligations under the terms of the instrument. We place our cash equivalents and short-term investments with high credit-quality financial institutions. We invest our excess cash in commercial paper, readily marketable debt instruments and collateralized funds of U.S. and state government entities. We have established guidelines relative to credit ratings, diversification and maturities that seek to maintain safety and liquidity.

A majority of our trade receivables are derived from sales in various geographic areas, principally the U.S., Europe, Japan, Taiwan and the rest of Asia, to large companies within the integrated circuit and nanotechnology industries. We perform ongoing credit evaluations of our customers’ financial condition and require collateral, whenever deemed necessary. We maintain an allowance for uncollectible accounts receivable based upon expected collectibility and estimated returns and allowances. This reserve is established based upon historical trends, current economic conditions, delinquency status based on contractual terms and an analysis of specific exposures. As of December 31, 2005 and 2004, the recorded value of our accounts receivable approximated fair value due to the short-term nature of our accounts receivable.

Sole-source and single-source suppliers provide critical components and services for the manufacture of our products. The reliance on sole or limited groups of suppliers may subject us from time to time to quality, allocation and pricing constraints.

3. BASIS OF PRESENTATION

The accompanying consolidated financial statements include the accounts of Ultratech and our subsidiaries, all of which are wholly owned. Intercompany balances and transactions have been eliminated.

The U.S. dollar is the functional currency for all foreign operations. Foreign exchange gains and losses, which result from the process of remeasuring foreign currency financial statements into U.S. dollars or from foreign currency exchange transactions during the period, have been immaterial and are included in interest and other income, net.

Use of Estimates

The preparation of the financial statements and related disclosures in conformity with accounting principles generally accepted in the United States requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities at the date of the consolidated financial statements. By their nature, these estimates and judgments are subject to an inherent degree of uncertainty. On an ongoing basis, management evaluates its estimates, including those related to inventories, warranty obligations, purchase order commitments, asset retirement obligations, bad debts, estimated useful lives of fixed assets, asset impairment, income taxes, intangible assets, restructuring and contingencies and litigation. Management

bases its estimates on historical experience and on various other analyses and assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

4. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Cash equivalents

Cash equivalents consist of highly liquid investments with a maturity date at acquisition of three months or less. The carrying value of cash equivalents approximates fair value.

Investments

Management determines the appropriate classification of its investments at the time of purchase and re-evaluates the classification at each balance sheet date. At December 31, 2005 and 2004, all investments and cash equivalents in our portfolio were classified as “available for sale” and are stated at fair value, with the unrealized gains and losses, net of tax, reported in accumulated other comprehensive income (loss), as a separate component of stockholders’ equity.

The amortized cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization, as well as interest, dividends, realized gains and losses and declines in value judged to be other than temporary are included in interest and other income, net. The cost of securities sold is based on the specific identification method.

Allowances for Bad Debts

We maintain an allowance for uncollectible accounts receivable based upon expected collectibility. This reserve is established based upon historical trends, current economic conditions, delinquency status based on contractual terms and an analysis of specific exposures.

Inventories

Inventories are stated at the lower of cost or market. Cost is determined using the first-in, first-out (FIFO) method. The semiconductor industry is characterized by rapid technological change, changes in customer requirements and evolving industry standards. We perform a detailed assessment of inventory at each balance sheet date, which includes a review of, among other factors, demand requirements and market conditions. Based on this analysis, we record adjustments, when appropriate, to reflect inventory at lower of cost or market.

Long-lived assets

Equipment and leasehold improvements are stated at cost, less accumulated depreciation and amortization. Equipment is depreciated on a straight-line basis over the estimated useful lives (three to ten years). Leasehold improvements are amortized on a straight-line basis over the life of the related assets or the lease term, whichever is shorter. The depreciation expense for the year ended 2005 was $6.4 million.

Demonstration inventory is stated at cost, less accumulated amortization. Demonstration inventory is amortized to its estimated net realizable value as a used system over its estimated useful life as a demonstration system, generally three years.

Intangible assets are carried at cost, less accumulated amortization, which is being recognized on a straight-line basis over the economic lives of the respective assets, generally five to seven years. Intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying

amount of the related asset may not be recoverable. As of December 31, 2005, all the intangible assets had been fully amortized. The gross value of intangible assets as of December 31, 2004 was $2.0 million. Intangible assets are presented in the statement of financial position net of accumulated amortization of $1.9 million as of December 31, 2004. Amortization of intangible assets was $0.1 million, $0.4 million and $0.4 million for the years ended December 31, 2005, 2004 and 2003.

We review long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of these assets may not be recoverable. We assess these assets for impairment based on estimated future cash flows from these assets. Other than as noted on Footnote 11, “Restructure of Operations”, no impairment charges have been recorded during the three years ended December 31, 2005.

Asset Retirement Obligation

In the fourth quarter 2005 we adopted FASB Interpretation No. 47, “Accounting for Contingent Asset Retirement Obligations” (“FIN 47”), an interpretation of FASB Statement No. 143, “Asset Retirement Obligations” (“SFAS 143”). FIN 47 clarifies that the term “conditional asset retirement obligation” as used in SFAS 143 refers to a legal obligation to perform an asset retirement activity in which the timing and (or) method of settlement are conditional on a future event that may or may not be within the control of the entity. An entity is required to recognize a liability for the fair value of a conditional asset retirement obligation if the fair value of the liability can be reasonably estimated, even if conditional on a future event. As permitted, we recognized the effect of applying FIN 47 as a cumulative effect of a change in accounting principle. Our adoption of FIN 47 resulted in an increase in net equipment and leasehold improvements of approximately $1.0 million, recognition of an asset retirement obligation (“ARO”) liability of $2.1 million, and a cumulative effect of adoption of $1.1 million, or $0.05 per share, for the year ended December 31, 2005. The ARO liability is principally for estimable asset retirement obligations related to remediation costs, which we estimate will be incurred upon the expiration of certain operating leases.

The following table reflects unaudited pro forma presentations of the Company’s results of operations and asset retirement obligations as if FIN 47 had been retrospectively applied:

Derivative Instruments and Hedging

Currency forward contracts that are used by us to hedge the risk that unremitted Japanese yen denominated receipts from customers for forecasted sales of equipment after receipt of customer purchase orders may be adversely affected by changes in foreign currency exchange rates are designated as cash flow hedges. The maturity of these instruments is generally nine months or less. At December 31, 2005, we had taken action to hedge 100%, or approximately $3.3 million, of these Japanese yen denominated exposures. We often close currency forward contracts by entering into an offsetting contract.

Ultratech records these currency forward contracts at fair value in our consolidated balance sheets as prepaid expenses and other current assets or accrued expenses, as appropriate, and the related gains or losses on these contracts are recorded in accumulated other comprehensive income (loss) as a component of stockholders’ equity. These deferred gains and losses are recognized in income, as a component of revenue, in the period in which the forecasted sales being hedged are recognized in income. However, to the extent that any of these contracts are not considered to be perfectly effective in offsetting the change in the value of the forecasted sales being hedged, any changes in fair value relating to the ineffective portion of these contracts are immediately recognized in income as a component of interest and other income, net. The effectiveness of the hedge is measured using the forward rates to value the forward contract and the underlying hedged transaction. The ineffective portions of the hedges were not material to the periods presented. Should we terminate a derivative designated as a cash-flow hedge, the derivative is settled for cash and the fair value of the asset or liability, as appropriate, is written off.

Currency forward contracts are also used to offset the currency risk of Japanese yen denominated assets and liabilities. We record these currency forward contracts at fair value in our consolidated balance sheets as prepaid expenses and other current assets or accrued expenses, as appropriate, and the related gains or losses on these contracts are recognized as a component of interest and other income, net.

At December 31, 2005 and 2004, we had currency forward contracts at fixed rates of exchange for the sale of Japanese yen of $6.5 million and $13.9 million, respectively. We had recorded $0.3 million accumulated gain and $0.3 million of accumulated losses as components of other comprehensive income (loss) at December 31, 2005 and 2004, respectively. The fair value of derivatives classified as cash-flow hedges at December 31, 2005 and 2004 was an asset of $0.2 million and a liability of $0.3 million, respectively. The fair value of other derivatives at December 31, 2004 was a liability of $0.2 million .

Revenue recognition

product specifications prior to shipment and management deems that no significant uncertainties as to product performance exist.

Costs incurred for shipping and handling are included in cost of sales.

Warranty Accrual

We generally warrant our products for material and labor to repair the product for a period of 12 months for new products, or 3 months for refurbished products, from the date of customer acceptance. Accordingly, an accrual for the estimated cost of the warranty is recorded at the time the product is shipped and is recorded in the statement of operations at the time revenue is recognized.

Research, development, and engineering expenses

We are actively engaged in basic technology and applied research programs designed to develop new products and product applications. In addition, substantial ongoing product and process improvement engineering and support programs relating to existing products are conducted within engineering departments and elsewhere. Research, development and engineering costs are charged to operations as incurred.

Deferred Income Taxes

We record a valuation allowance to reduce our net deferred tax assets to the amount that is more likely than not to be realized. Based on the uncertainty of future taxable income, we have presently fully reserved our domestic deferred tax assets.

Impact of recently issued accounting standards

In June 2005, the FASB issued Statement No. 154, “Accounting Changes and Error Corrections” (SFAS 154), a replacement of APB Opinion No. 20, “Accounting Changes”, and Statement No. 3,

“Reporting Accounting Changes in Interim Financial Statements.” SFAS 154 changes the requirements for the accounting for and the reporting of a change in accounting principle. Previously, most voluntary changes in accounting principles required recognition by recording a cumulative effect adjustment within net income in the period of change. SFAS 154 requires retrospective application to prior periods’ financial statements, unless it is impracticable to determine either the specific period effects or the cumulative effect of the change. SFAS 154 is effective for accounting changes made in fiscal years beginning after December 15, 2005.

In March 2005, the SEC released SEC Staff Accounting Bulletin No. 107 (SAB 107). SAB 107 provides the SEC staff position regarding the application of SFAS 123R, Share-Based Payment. SAB 107 contains interpretive guidance relating to the interaction between SFAS 123R and certain SEC rules and regulations, as well as the staff’s views regarding the valuation of share-based payment arrangements for public companies. SAB 107 also highlights the importance of disclosures made related to the accounting for share-based payment transactions.

On December 16, 2004, the Financial Accounting Standards Board (FASB) issued FASB Statement No. 123 (revised 2004), Share-Based Payment, which is a revision of FASB Statement No. 123, Accounting for Stock-Based Compensation. Statement 123(R) supersedes APB Opinion No. 25, Accounting for Stock Issued to Employees, and amends FASB Statement No. 95, Statement of Cash Flows. Generally, the approach in Statement 123(R) is similar to the approach described in Statement 123. However, Statement 123(R) requires all share-based payments to employees, including grants of employee stock options, to be recognized in the income statement based on their fair values. Pro forma disclosure will no longer be an alternative. In April 2005, the Securities and Exchange Commission announced the adoption of a new rule that amends the effective date of FAS 123(R). The effective date of the new standard under these new rules for our consolidated financial statements is January 1, 2006.

As permitted by Statement 123, we account for share-based payments to employees using the intrinsic value method and, as such, generally recognize no compensation cost for employee stock options through the year ended December 31, 2005. Accordingly, the adoption of Statement 123(R)’s fair value method will have a material impact on our results of operations. The actual impact will depend on levels and terms of future share-based payments granted, as well as other variables. The adoption of Statement 123(R)’s fair value method will have no impact on our overall financial position. However, had we adopted Statement 123(R) in prior periods, the impact of that standard would have approximated the impact of Statement 123 as described in the disclosure of pro forma net income (loss) and net income (loss) per share in Note 5 to our condensed consolidated financial statements.

5. STOCK-BASED COMPENSATION

At December 31, 2005, Ultratech had several stock-based employee compensation plans, which are described more fully in Note 12. We account for these plans under the intrinsic value method because, as discussed below, the fair value accounting method requires use of option valuation models that were not developed for use in valuing employee stock options. Under the intrinsic value method no stock-based employee compensation cost is reflected in net income, as all options granted under those plans had an exercise price equal to the market value of the underlying common stock on the date of grant.

Pro forma information regarding net income (loss) and net income (loss) per share is required as if we had accounted for our employee stock options (including purchase rights issued under the Employee Stock Purchase Plan) under the fair value method. The Black-Scholes option valuation model was developed for use in estimating the fair value of traded options that have no vesting restrictions and are fully transferable. In addition, option valuation models require the input of highly subjective assumptions including the expected stock price volatility. Because our employee stock options have characteristics significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the fair value estimate, in management’s opinion, the existing models do not necessarily provide a reliable single measure of the fair value of our employee stock options.

The following table illustrates the effect on net income and earnings per share if we had applied the fair value recognition method to account for stock-based employee compensation.

	Years Ended December 31,
In thousands, except per share amounts	2005			2004			2003
Net income (loss) as reported	$	(2,343	)	$	624		$	7,566

Included in the fair value stock-based employee compensation expense above for 2004, was $16.2 million resulting from the acceleration of vesting of options to purchase approximately 2.3 million shares of common stock for all optionees, except for non-employee members of the Board of Directors, whose exercise price, which ranges from $13.36 to $31.38 per share, exceeded the market price of our stock on the respective dates of acceleration, June 25 , 2004 and July 19, 2004. We have never repriced stock options, thus, the exercise prices for the stock options accelerated were unchanged. These unvested “underwater” options, in our opinion, represented negligible value in retaining or motivating our employees. We believe, however, that fully vesting these options favorably motivates our employees to continue with our company and to work to increase stockholder value. Further, fully vesting these options also eliminates the need to recognize remaining unrecognized non-cash compensation expense in future periods in the Company’s statement of operations upon the adoption of Financial Accounting Standards Board Statement of Financial Accounting Standards No. 123 (Revised 2004), Share-Based Payment (“SFAS 123R”). As the exercise price of all the stock options affected was greater than their fair market price on the date of vesting acceleration, there was no impact, under the intrinsic value method, on our consolidated statements of operations.

The table above used the following weighted-average assumptions to estimate the fair value of stock options at the date of grant using the Black-Scholes option-pricing model.

	2005		2004		2003
Expected life (in years): stock options	4.1		2.2		3.5
Expected life (in years): Employee Stock Purchase Plan	N/A		0.50		1.25
Risk-free interest rate	3.90	%	2.54	%	2.48	%
Volatility factor	0.51		0.60		0.71
Dividend yield	0	%	0	%	0	%

The 2004 information in the table above reflects the termination of our Employee Stock Purchase Plan in July 2004 and the impact of the acceleration of vesting of underwater stock options discussed previously. The weighted-average expected life of stock options is computed assuming a multiple-point approach for each grant based upon either annual average vesting periods or the dates that resale restrictions are removed, depending upon the specific terms of the grant being measured. The weighted-average fair value per share of stock options granted during 2005, 2004 and 2003 was $7.13, $5.90 and $8.82, respectively.

The weighted average fair value of purchase rights granted under our Employee Stock Purchase Plan during 2004 and 2003 was $8.21 and $5.00, respectively.

For purposes of pro forma disclosures, the estimated fair value of options granted is amortized to expense over the stock options’ vesting period and the Employee Stock Purchase Plan’s six month purchase period. Certain stock option grants are divided into annual vesting periods, resulting in the recognition of approximately 50% of the total compensation expense of the grant in the first year. Other stock options grants, primarily grants with cliff vesting terms, were amortized into expenses on a straight-line basis from grant date to vesting date. Additionally, the potential tax benefit associated with the issuance of incentive stock options is not reflected until realized upon the disqualifying disposition of the shares.

6. BASIC AND DILUTED NET INCOME (LOSS) PER SHARE

The following sets forth the computation of basic and diluted net income (loss) per share:

	Years Ended December 31,

Cumulative effect of the adoption of FIN 47	$	(0.05	)	$	—	$	—
Net income (loss)	$	(0.10	)	$	0.03	$	0.31

For the year ended December 31, 2005, options to purchase 6,443,948 shares of Common Stock at an average exercise price of $17.71 were excluded from the computation of diluted net loss per share as the effect would have been anti-dilutive. This compares to the exclusion of 2,245,000 options at an average exercise price of $25.25 for the year ended December 31, 2004 and 1,127,000 options at an average exercise price of $25.26 for the year ended December 31, 2003. Options are anti-dilutive when we have a net loss or when the exercise price of the stock option is greater than the average market price of our Common Stock.

7. ACCUMULATED OTHER COMPREHENSIVE INCOME (LOSS)

Comprehensive income (loss), as presented on the Consolidated Statements of Stockholder’s Equity, includes net income (loss) and other comprehensive income (loss). Accumulated other comprehensive income (loss) is comprised of the following items, net of tax:

	December 31,
In thousands:	2005			2004
Unrealized gains (losses) on:
Available-for-sale investments	$	(1,200	)	$	(194	)
Foreign exchange contracts	314			(295		)
Accumulated other comprehensive loss at end of year	$	(886	)	$	(489	)

The amount of gain (loss) on foreign exchange contracts reclassified to earnings was ($247,000), ($655,000) and ($248,000) in 2005, 2004 and 2003, respectively. The amount of loss on available-for-sale investments reclassified to earnings was immaterial in each year of the three-year period ended December 31, 2005.

8. INVESTMENTS

We classified all of our investments as “available for sale” as of December 31, 2005 and 2004. Accordingly, we state our investments at estimated fair value. Fair values are determined based on quoted market prices or pricing models using current market rates. We deem all investments to be available to meet current working capital requirements.

The following is a summary of our investments:

	December 31, 2005												December 31, 2004
Cash equivalents and Available-for-sale	Amortized			Accumulated Other Comprehensive						Estimated			Amortized			Accumulated Other Comprehensive						Estimated

The following is a reconciliation of our investments to the balance sheet classifications at December 31:

In thousands	2005		2004
Cash equivalents	$	33,083	$	43,767
Short-term investments	104,723		103,642
Investments, at estimated fair value	$	137,806	$	147,409

Gross realized gains and losses on sales of investments were not material in each of the three-years ended December 31, 2005.

The gross amortized cost and estimated fair value of our investments at December 31, 2005, by contractual maturity, are shown below. Expected maturities will differ from contractual maturities because the issuers of the securities may have the right to prepay obligations without prepayment penalties.

	Gross
	Amortized		Fair
In thousands	Cost		Value
Due in one year or less	$	74,702	$	74,406
Due after one year through five years	64,304		63,400
	$	139,006	$	137,806

The following table provides the breakdown of the cash equivalents and short-term investments with unrealized losses at December 31, 2005:

	In Loss Position for Less Than 12 Months					In Loss Position for More Than 12 Months					Total
			Gross					Gross					Gross
	Fair		Unrealized			Fair		Unrealized			Fair		Unrealized
Short-term investments, in thousands	Value		Losses			Value		Losses			Value		Losses
U.S. Treasury securities and obligations of U.S. government agencies	$	55,648		$	678	$	14,344		$	161	$	69,992		$	839
U.S. corporate debt securities	15,443			179		15,914			188		31,357			367
	$	71,091		$	857	$	30,258		$	349	$	101,349		$	1,206

We review our investment portfolio monthly to identify and evaluate investments that have indications of possible impairment. Factors considered in determining whether a loss is temporary include credit quality and our ability and intent to hold the investment for a period of time sufficient to allow for any anticipated recovery in market value. If the credit quality of the investment does not meet the credit quality requirements of our investment policy, we will also consider additional factors such as the length of time and extent to which fair value has been less than the cost basis and the financial condition and near-term prospects of the investee. The gross unrealized losses associated with our cash equivalents and short-term investments were primarily caused by an increase in interest rates during 2005. We have determined that the gross unrealized losses on our cash equivalents and short-term investments at December 31, 2005 are temporary in nature because each investment meets the credit quality requirements of our investment policy.

Warranty Accrual

We generally warrant our products for a period of 12 months for new products, or 3 months for refurbished products, from the date of customer acceptance for material and labor to repair the product; accordingly, an accrual for the estimated cost of the warranty is recorded at the time the product is shipped. Extended warranty terms, if granted, result in deferral of revenue equating to our standard pricing for similar service contracts. Recognition of the related warranty cost is deferred until product revenue is recognized. Factors that affect our warranty liability include the number of installed units, historical and anticipated rates of warranty claims, and cost per claim. We periodically assess the adequacy of our recorded warranty liabilities and adjust the amounts as necessary.

Changes in our product liability are as follows:

10. NOTES PAYABLE

In December 2004, we entered into a line of credit agreement with a brokerage firm. Under the terms of this agreement, we may borrow funds at a cost equal to the current Federal funds rate plus 100 basis points (5.25% as of December 31, 2005). Certain of our cash, cash equivalents and short-term investments secure borrowings outstanding under this facility. Funds are advanced to us under this facility based on pre-determined advance rates on the cash and securities held by us in this brokerage account. This agreement has no set expiration date and there are no loan covenants, other than the aforementioned collateral requirement. As of December 31, 2005, $4.3 million was outstanding under this facility, with a related collateral requirement of approximately $5.7 million of our cash, cash equivalents and short-term investments. As of December 31, 2004, $7.9 million was outstanding under a similar facility, with a related collateral requirement of approximately $10.5 million of our cash, cash equivalents and short-term investments.

11. RESTRUCTURE OF OPERATIONS

In September 2001, Ultratech reached a decision to consolidate our manufacturing operations. In connection with this decision, we reached a settlement with the landlord of our Wilmington, Massachusetts facility in October 2003. As a result of this settlement, we recognized a credit to operations of $0.6 million.

12. STOCKHOLDERS’ EQUITY

1993 Stock Option Plan/Stock Issuance Plan

Under Ultratech’s 1993 Stock Option Plan/Stock Issuance Plan, as amended, qualified employees, non-employee Board members and consultants may receive options to purchase shares of Common Stock at no less than 100% of fair value at the grant date. These options historically have vested in equal monthly installments over a period of approximately four years, with a minimum vesting period of twelve months from the grant date, and generally expire ten years from the date of grant. In 2005 and 2004, certain options were granted with no vesting requirements and others were granted with non-standard vesting periods that provided full vesting as of December 31, 2005 and 2004. Some of these option grants contain sales restrictions and some of these restriction provisions were linked to performance targets. In 2003, certain options were granted with non-standard vesting periods that provided for full vesting as early as twelve months from date of grant if certain performance targets were met, and deferred any vesting until fifty months from the date of grant if performance targets were not met. In 2003, we also granted options to certain executives that call for acceleration of vesting and extension of the early termination provisions should certain events occur. The plan terminates on the earlier of February 28, 2011 or the date on which all shares available for issuance under the plan have been issued. The plan contains an automatic share increase feature pursuant to which the share reserve will automatically increase on the first trading day in January of each calendar year, through 2006, by an amount equal to four percent (4%) of the total number of shares of Common Stock outstanding on the last trading day in December of the immediately preceding calendar year, but in no event would such annual increase exceed 1.7 million shares, subject to adjustment in the event of certain changes to our capital structure. Under the plan, approximately 131,000, 56,000, and 171,000 options were available for issuance at December 31, 2005, 2004 and 2003, respectively.

1998 Supplemental Stock Option/Stock Issuance Plan

Under our 1998 Supplemental Stock Option/Stock Issuance Plan, as amended, qualified employees may receive options to purchase shares of Common Stock at 100% or above of fair value at certain specified dates. These options generally vest in equal monthly installments over a period of approximately four years, with a minimum vesting period of twelve months from grant date, and generally expire ten years from date of grant. The plan will terminate on the earlier of October 19, 2008, or the date on which all shares available for issuance under the plan have been issued. Under the plan, approximately 43,000, 16,000, and 18,000 options were available for issuance at December 31, 2005, 2004 and 2003, respectively.

Employee Stock Purchase Plan

Under the provisions of our Employee Stock Purchase Plan, virtually all employees could purchase Common Stock through payroll deductions at 85% of the lower of the fair market value of the Common Stock on the first or last day of the offering period. In February 2001, we commenced a plan that allows twenty-four month offering periods with semi-annual purchase dates. In July 2004, we terminated the Employee Stock Purchase Plan.

Treasury Stock

On September 19, 2005, the Company’s Board of Directors authorized the repurchase of up to $30 million of its common stock in the open market at then prevailing market prices during the period commencing September 19, 2005 through September 30, 2007. As of December 31, 2005, the Company had repurchased 644,535 shares of its common stock for a total of $9.2 million.

Shareholder Rights Plan

Our Shareholder Rights Plan provides that Preferred Share Purchase Rights (“Rights”) are attached at the rate of one Right on each outstanding share of our Common Stock held by stockholders. These rights expire on February 9, 2007.

The Rights will be exercisable only if a person or group acquires 15% or more of our Common Stock or announces a tender offer the consummation of which would result in ownership by a person or group of 15% or more of our Common Stock. Each Right will entitle stockholders to buy one one-hundredth of a share of a new series of Junior Participating Preferred Stock at an exercise price of $145.00 upon certain events.

The Rights are redeemable, in whole but not in part, at the option of the Board of Directors at $.01 per Right, at any time within 10 days of the date they become exercisable and in certain other circumstances and will not become exercisable in certain instances where our Board of Directors approves a transaction. The Rights will not prevent a takeover of Ultratech, but are designed to encourage anyone seeking to acquire us to negotiate with our Board of Directors.

Shares reserved for issuance under the plan were 350,000 at December 31, 2005.

13. EMPLOYEE BENEFIT PLANS

Employee bonus plans

We currently sponsor a profit sharing plan and an executive incentive bonus plan that distribute employee awards based on the achievement of predetermined targets. We have not recognized expense under these various employee bonus plans for 2005, 2004 and 2003.

Employee savings and retirement plans

Ultratech sponsors a 401(k) employee salary deferral plan that allows voluntary contributions by all full-time employees of from 1% to 20% of their pretax earnings. During the three years ended December 31, 2005, company contributions made to this plan were $0.4, $0.0, and $0.0 million, respectively. These company contributions generally become 20 percent vested at the end of an employee’s first year of service from the date of hire with the Company, and vest 20 percent per year of service thereafter until they become fully vested at the end of five years of service. We also sponsor an executive non-qualified deferred compensation plan (the “Plan”) that allows qualifying executives to defer current cash compensation. At December 31, 2005, Plan assets, representing the cash surrender value of life insurance policies held by us, and liabilities were approximately $2.0 million and $1.9 million, respectively, and are included in our consolidated balance sheets under the captions “other assets” and “other liabilities.” In conjunction with this plan, we recognized $0.1, $0.1, and $0.0 million of expense for the years ended December 31, 2005, 2004 and 2003, respectively.

Postretirement benefits

The Company has committed to providing lifetime post-retirement medical and dental benefits to the Chief Executive Officer and his spouse, commencing after his retirement. As of December 31, 2005, the actuarial present value of these benefits has been estimated to be $475,000. The Company’s liabilities as of December 31, 2005 include $475,000 to cover this obligation. This obligation was measured using a discount rate of 5.50% and future health care cost increases ranging from 14% in 2006 to 6% in 2014 and later years.

Based upon the weight of available evidence, which includes our historical operating performance and carry back potential, we have determined that a valuation allowance continues to be necessary for all tax jurisdictions, except Japan.

The net valuation allowance increased by $1.1, $5.5 and $3.5 million during the years ended December 31, 2005, 2004 and 2003, respectively. Approximately $13.3 million of the valuation allowance as of December 31, 2005 is attributable to stock options, the benefit of which will be credited to paid-in capital when realized.

As of December 31, 2005, we had net operating loss carryforwards for federal and state tax purposes of $107 million and $45 million, respectively. We also had federal research and development tax credit carryforwards of approximately $9.2 million. The federal and state net operating loss carryforwards will expire at various dates beginning in 2006 through 2025, if not utilized. The federal tax credit carryforwards will expire at various dates beginning in 2011 through 2025, if not utilized.

Utilization of our net operating loss and tax credits carryforwards may be subject to substantial annual limitation due to the ownership change limitations provided by the Internal Revenue Code and similar state provisions. Such an annual limitation could result in the expiration of the net operating losses and credits before utilization.

15. COMMITMENTS AND CONTINGENCIES

We lease our facilities, and certain equipment under operating leases expiring through December 2015. Certain of our leasing arrangements subject us to letter of credit requirements. The leases for our headquarters and manufacturing operations contain a five-year renewal option subject to a fair market value pricing adjustment. As of December 31, 2005, the minimum annual rental commitments are as follows:

	in thousands
2006		$	4,787
2007		4,639
2008		4,759
2009		4,528
2010		2,891
Thereafter		423
		$	22,027

Rent expense was approximately $4.2 million, $4.2 million and $4.8 million for the years ended December 31, 2005, 2004 and 2003, respectively.

Under terms of certain of our leases, we are obligated to provide a $2.0 million bank letter of credit as security to the landlord.

ASML invalidating three claims of the patent for lack of enablement. The Court also awarded ASML approximately $330,000 in costs. Ultratech intends to appeal the final judgment.

16. FINANCIAL GUARANTEES

Our off-balance sheet transactions consist of certain financial guarantees, both express and implied, related to indemnification for product liability, patent infringement and latent product defects. Other than liabilities recorded pursuant to known product defects, at December 31, 2005, we did not record a liability associated with these guarantees, as we have little or no history of costs associated with such indemnification requirements. Contingent liabilities associated with product liability may be mitigated by insurance coverage we maintain.
