This summary does not contain all of the information you should consider before investing in our common stock. Before you decide to invest in our common stock, you should carefully read the entire prospectus supplement, the accompanying prospectus and any related free writing prospectus, including the financial statements and related notes and other information incorporated by reference herein or therein and the matters set forth under the section of this prospectus supplement and the accompanying prospectus captioned “Risk Factors.”
Company Overview
nLIGHT, Inc., is a leading provider of high-power semiconductor and fiber lasers for industrial, microfabrication, and aerospace and defense applications. Headquartered in Vancouver, Washington, we design, develop and manufacture the critical elements of our lasers, and believe our vertically integrated business model enables us to rapidly introduce innovative products, control our costs and protect our intellectual property.
We design, manufacture, and sell a range of high-power semiconductor lasers and fiber lasers that are typically integrated into laser systems or manufacturing tools built by our customers. We also make fiber amplifiers and beam combination and control systems for use in high-energy laser systems in directed energy applications. Our vertical integration enables us to develop products that leverage the same underlying technology, thereby enabling us to offer innovative and reliable products to customers in each of our end markets.
We sell our products into three primary end markets: Industrial, Microfabrication, and Aerospace and Defense. Semiconductor and fiber lasers are displacing legacy lasers and non-laser energy sources across a wide range of applications in the Industrial, Microfabrication, and Aerospace and Defense markets. In the Industrial market, high-power semiconductor and fiber lasers have enabled the creation of next-generation industrial systems to perform manufacturing processes such as cutting, welding, and drilling, as well as advanced manufacturing techniques such as additive manufacturing. In the Microfabrication market, many of the critical microscale features incorporated into products in the automotive, electronics, medical, semiconductor and other markets are made commercially viable by the precise power delivery of lasers. In the Aerospace and Defense market, high-power semiconductor and fiber lasers are currently used across a wide range of mission critical applications, such as defending aircraft against missiles, and are enabling next-generation defense systems.

(2)    We use Adjusted EBITDA, a non-GAAP financial measure, to help us evaluate our business, measure our performance, identify trends affecting our business, formulate business plans and make strategic decisions. In addition to our results determined in accordance with GAAP, we believe Adjusted EBITDA is a meaningful measure of performance as it is commonly utilized by us and the investment community to analyze operating performance in our industry.
    We define Adjusted EBITDA as net income (loss) adjusted for income tax expense, other non-operating income or expense, interest income or expense, depreciation and amortization, stock-based compensation, acquisition and integration-related costs, and other special items as determined by management, as applicable. The following table sets forth Adjusted EBITDA and a reconciliation from net income (loss), the most comparable GAAP measure, for the periods presented.

    Adjusted EBITDA is a non-GAAP financial measure that reflects an additional way of viewing aspects of our business that, when viewed with our GAAP results and the accompanying reconciliation to the corresponding GAAP financial measure included in the table above, may provide a more complete understanding of factors and trends affecting our business. This non-GAAP financial measure should not be relied upon to the exclusion of GAAP financial measures.
    We believe that the non-GAAP measure disclosed herein is only useful as an additional tool to help management and investors make informed decisions about our financial and operating performance. By definition, non-GAAP measures do not give a full understanding of our performance. To be useful, they must be used in conjunction with the comparable GAAP measures. In addition, non-GAAP financial measures are not standardized. It may not be possible to compare our financial measures with other companies’ non-GAAP financial measures having the same or similar names. We strongly encourage investors to review our consolidated financial statements and the notes thereto in their entirety and not to rely on any single financial measure.

RISK FACTORS
Investing in our common stock involves a high degree of risk. You should carefully consider the risks described below, as well as all other information included in this prospectus supplement, the accompanying prospectus and in our other filings with the SEC incorporated by reference into this prospectus supplement before you decide to purchase shares of our common stock. If any of the following risks actually occurs, our business, financial condition, operating results, prospects and ability to accomplish our strategic objectives could be materially harmed. As a result, the trading price of our common stock could decline and you could lose all or part of your investment. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also impair our business operations and the market price of our common stock.
Risks Related to Our Industry and the Markets We Serve
The markets for our products are highly competitive. If we fail to compete successfully, our business, financial condition, results of operations and growth prospects will be materially adversely affected.
The industries in which we operate have significant price and technological competition. We compete with companies providing semiconductor and fiber lasers, and with companies offering conventional laser or non-laser solutions for the applications we target. Some of our competitors are larger and have substantially greater manufacturing, financial and research and development resources and larger installed customer bases than we do. Some of these competitors may be state-owned or otherwise receive substantial government subsidies allowing them to compete more aggressively. Certain of these competitors also have higher sales volume than we do, which can enable them to lower the prices of their products. Moreover, our OEM customers’ internal production of laser technologies presents additional competitive pressure. To compete, we have reduced prices of some of our products in the past and we may be forced to lower our prices further in the future, which could negatively impact our revenues and gross margins. To remain competitive, we believe that we will be required to continue to invest significantly in research and development and manufacturing facilities. We may not have sufficient resources to continue to make these investments and we may not be able to make the technological advances or price adjustments necessary to compete successfully. Any failure to compete successfully will materially adversely affect our business, financial condition, results of operations and growth prospects.
Changes in the markets we serve could materially adversely affect our revenues and profitability.
Our results of operations may vary based on the impact of changes in the industries we serve or in the global economy. For our products sold to the Industrial market, we believe demand is largely based on general economic conditions and we cannot predict the timing, strength or duration of any economic slowdown or recovery, whether global, regional or within specific markets. For the Microfabrication market, a portion of our revenues depends on the demand for our products from semiconductor equipment companies. The semiconductor equipment market has historically been characterized by sudden and severe cyclical variations in product supply and demand, which have often severely affected the demand for manufacturing equipment, including laser-based tools and systems, and which limits our ability to predict our business prospects and financial results in this market. The Aerospace and Defense market is largely dependent on government budgets, in particular defense budgets, which are driven by numerous factors, including geopolitical events, macroeconomic conditions and the ability of the U.S. government to enact relevant legislation. As a result, our future revenues are subject in part to the uncertainties of governmental budgeting and appropriations and national defense policies and priorities, constraints of the budgetary process and timing and potential changes to these policies and priorities, all of which are beyond our control. Many of our customers in the defense industry are subcontractors that must negotiate our proposals with the U.S. government. Our continuing relationship with these customers and the ability of these customers to pay for our products dependent on the U.S. government’s decision to accept or reject our customers’ terms, which can be delayed for a substantial period of time and is largely outside of our control. Such delays could result in decreased revenues and could materially adversely harm our results of operations in any given period.
Products in the laser industry are experiencing declining average selling prices, and any future success depends in part on our ability to increase our volumes and decrease our costs to offset potential declines in the average selling prices of our products.
Products in the laser industries generally, and our products specifically, have experienced and may in the future experience a significant decline in average selling prices (ASPs), on maturing products due to increased competition and price pressures from customers. As competing products become more widely available, the ASPs of our products may decrease, and such decreases may vary by product and market. Due to the fixed cost of production, the average cost per unit
S-6

of our products typically declines as our production volumes rise. For this reason, we may decide to offer products at ASPs that result in low initial gross margins to us with an intention to drive sales and production volumes higher, in turn lowering our average cost per unit. In addition, we have discontinued and may continue to discontinue certain products if the ASPs for certain products do not generate sufficient gross margin. Because of these factors, we have experienced, and we may continue to experience, fluctuations in our results of operations on a quarterly or annual basis. If the ASPs of our products decline and we are unable to increase our unit volumes, introduce new or enhanced products with higher ASPs or reduce manufacturing costs to offset anticipated decreases in the prices of our existing products, our gross margins could decline, which in turn could materially adversely affect our business, financial condition, results of operations and growth prospects.
We participate in markets that are subject to rapid technological change and require significant research and development expenses to develop and maintain products that can achieve market acceptance.
The markets for our products are characterized by rapid technological change, frequent product introductions, substantial capital investment, volatility of product supply and demand, changing customer requirements and evolving industry standards. Our future performance depends in part on our successful development, introduction and market acceptance of new and enhanced products that address these changes and current and potential customer requirements. To the extent customers defer or cancel orders for existing products due to a slowdown in demand or in the expectation of a new product release, or if there is any delay in development or introduction of our new products or enhancements of our products, our business, financial condition, results of operations and growth prospects would be materially adversely affected. We also may not be able to develop the underlying core technologies necessary to create new products and enhancements, or to license these technologies from third parties. Product development delays may result from numerous factors, including:
•changing product specifications and customer requirements;
•unanticipated engineering complexities;
•expense reduction measures we have implemented, and others we may implement, to conserve our cash and attempt to sustain profitability;
•difficulties in hiring and retaining necessary technical personnel;
•difficulties in reallocating engineering resources and overcoming resource limitations; and
•changing market or competitive product requirements.
Further, the development of new, technologically advanced products is a complex and uncertain process requiring high levels of innovation and highly skilled engineering and development personnel, as well as the accurate anticipation of technological and market trends. We typically invest substantial resources in advance of material sales of our products to our customers. We cannot assure you that our expenditures for research and development will result in the introduction of new products or, if such products are introduced, that those products will achieve sufficient market acceptance or generate revenues to offset the costs of development. Ramping of production capacity also entails risks of delays which can limit our ability to realize the full benefit of the new product introduction. We cannot assure you that we will be able to identify, develop, manufacture, market or support new or enhanced products successfully. Additionally, our product offerings may become obsolete given the frequent introduction of alternative technologies. If our products fail to gain and maintain market acceptance, it could materially adversely affect our business, financial condition, results of operations and growth prospects.
Risks Related to Our Business and Operations
We have a history of losses, and as our operating costs increase we may not be able to generate sufficient revenues to achieve or maintain profitability in the future.
We have incurred recurring net losses since our inception in 2000 and expect our operating costs to continue to increase in future periods as we expend substantial financial and other resources on, among other things, business and headcount expansion in operations, sales and marketing, research and development, and administration as a public company. These expenditures may not result in additional revenues or the growth of our business. If we fail to grow revenues or to sustain profitability while our operating costs increase, our business, financial condition, results of operations and growth prospects will be materially adversely affected.
Our revenue growth rate in prior periods may not be indicative of our future performance.
Our historical revenue growth rate may not be indicative of future growth and we may not achieve similar revenue growth rates in future periods. You should not rely on our revenues for any prior quarterly or annual periods as an indication
S-7

of our future revenues or revenue growth. Our results of operations may vary as a result of a number of factors, including our ability to execute on our business strategy and expand our manufacturing capacity, the general economic conditions and the legal and regulatory environment in the United States, China and globally, as well as other factors that are outside of our control.
We have high levels of fixed costs and inventory levels that may materially adversely affect our gross profits and results of operations if demand for our products declines or we maintain excess inventory levels.
We conduct our own manufacturing operations and have a high fixed cost base, including significant costs for the employees in our manufacturing operations. We may not be able to adjust our production levels or fixed costs quickly enough or sufficiently to adapt to rapidly changing market conditions. Gross profit, in absolute dollars and as a percentage of revenues, is impacted by our volumes, product sales mix, the corresponding absorption of fixed manufacturing overhead expenses, production costs and manufacturing yields. In addition, because we design and manufacture our key components, insufficient demand for our products will subject us to the risks of high inventory carrying costs and increased inventory obsolescence. If our capacity and production levels are not properly sized in relation to expected demand, or if anticipated sales do not occur, we may need to record write-downs for excess or obsolete inventory.
Our operations are vulnerable to disruptions including pandemics, such as COVID-19, which have disrupted and likely will continue to disrupt our manufacturing and supply chain and adversely affect our business and operating results.
We are vulnerable to the economic effects of public health crises and other disruptions, including the ongoing COVID-19 pandemic. The impact of COVID-19 on our end-market demand, including delays in new capital expenditure decisions and implementations, restrictions on individual and business activities, and global liquidity concerns, has created significant volatility in the macro-economic environment and led to reduced economic activity. In response to government restrictions around the world, some of our non-manufacturing and technical service personnel outside of China have been primarily working from home since March 2020. Our global manufacturing operations, including our U.S. facilities located in Vancouver and Camas, Washington, Hillsboro, Oregon, and Longmont, Colorado are considered essential businesses and therefore continue to operate. Our facility in Lohja, Finland also continues to operate. Our Shanghai manufacturing facility was temporarily closed in the first quarter of 2020.
The full impact of the COVID-19 pandemic on our financial condition and results of operations will depend on future events and developments, such as the duration and magnitude of the pandemic and the conditions and timing under which restrictions will be lifted or re-imposed, impacts on our supply and distribution chains as well as our customers, the demand for our products, and whether the pandemic leads to recessionary conditions in any of our key markets. As such, the ultimate impact on our financial condition and results of operations cannot be determined at this time. We expect our business, financial condition, and results of operations may continue to be adversely affected by the COVID-19 pandemic. The COVID-19 pandemic may also intensify the risks described in the other risk factors disclosed in this prospectus supplement.
Our manufacturing capacity and operations may not be appropriate for future levels of demand and may materially adversely affect our gross margins.
When market demand increases, we must be able to rapidly and effectively increase our manufacturing capacity to meet increases in customer demand, and if we fail to do so we may lose business to our competitors and our relationships with our customers may be harmed. To maintain our competitive position and to meet anticipated demand for our products, we have invested significantly in the expansion and automation of our manufacturing and operations throughout the world and may continue to do so in the future. If the demand for our products does not increase or if our revenues decrease from current levels, we may have significant excess manufacturing capacity and under-absorption of our fixed costs, which could in turn materially adversely affect our gross margins and profitability. In connection with any expansion, we may incur cost overruns, construction delays, labor difficulties or regulatory issues which could cause our capital expenditures to be higher than what we currently anticipate, possibly by a material amount, which would in turn adversely impact our results of operations. Expansion activities can also cause disruptions to existing manufacturing capabilities. Moreover, we may experience higher costs due to yield loss, production inefficiencies and equipment problems until any operational issues associated with the addition of new equipment or opening of new manufacturing facilities are resolved.
We rely on a small number of customers for a significant portion of our revenues, and if we lose any of these customers or they significantly curtail their purchases of our products, our results of operations could be materially adversely affected.
S-8

We rely on a few customers for a significant portion of our revenues. We generally do not enter into long-term purchase agreements with our customers that obligate them to purchase our products. Our business is characterized by short-term purchase orders issued by our customers, which are likely to be favorable to those customers. If any of our principal customers discontinues its relationship with us, develops its own products instead of using ours, replaces us as a vendor for certain products or suffers downturns in its business resulting in a cancellation of orders or an inability to place new orders, then our business, financial condition, results of operations and growth prospects could be materially adversely affected.
If we are unable to develop new products, applications and end markets for our high-performance lasers and increase our market share in existing applications, our business, financial condition, results of operations and growth prospects will be materially adversely affected.
Our future success will depend in part on our ability to continue to generate sales of semiconductor lasers and fiber lasers in applications where legacy lasers have been used, or in new and developing markets and applications for lasers where they have not been used previously. As semiconductor and fiber lasers reach higher levels of penetration in core materials processing applications, the development of new applications, end markets and products outside our core applications becomes more important to our growth. Our current and potential customers may have substantial investment in, and know-how related to, their existing laser and non-laser technologies. Customers may be reluctant to change from incumbent suppliers or cease using their own solutions, or we may miss the design and procurement cycles of our customers. Many of our target markets, such as Industrial and Aerospace and Defense, have historically been slow to adopt new technologies. These markets often require long testing and qualification periods or lengthy government approval processes before admitting new suppliers or adopting new technologies.
Introduction of new products and product enhancements will require that we effectively transfer production processes from research and development to manufacturing and coordinate our efforts with those of our suppliers to achieve increased production volume rapidly. If we are unable to implement our strategy to develop new applications and end markets for our products or develop new products, our business, financial condition, results of operations and growth prospects could be materially adversely affected. In addition, any newly developed or enhanced products may not achieve market acceptance or may be rendered obsolete or less competitive by the introduction of new products by other companies.
The long sales cycles for our products may cause us to incur significant expenses without offsetting revenues.
Our products represent a large investment for our customers and they typically expend significant effort in evaluating, testing and qualifying our products before making a decision to purchase them, resulting in a lengthy initial sales cycle. While our customers are evaluating our products and before they place an order with us, we may incur substantial sales and marketing and research and development expenses to customize our products to the customers’ needs. We may also expend significant management efforts, increase manufacturing capacity and order long lead-time components or materials prior to receiving an order. Even after this evaluation process, a potential customer may decide not to purchase our products. As a result, these long sales cycles may cause us to incur significant expenses without receiving revenues to offset such expenses soon thereafter or at all. This, in turn, can materially adversely affect our business, financial condition, our results of operations and growth prospects.
Because we lack long-term purchase commitments from our customers, our revenues can be difficult to predict, which could lead to excess or obsolete inventory and materially adversely affect our results of operations.
Our business is characterized by short-term purchase orders and shipment schedules and, in some cases, orders may be canceled or delayed without penalty. As a result, it is difficult to forecast our revenues and to determine the appropriate levels of inventory required to meet future demand. This could lead to increased inventory levels and increased carrying costs and risk of excess or obsolete inventory due to unanticipated reductions in purchases by our customers. If we are unable to accurately forecast the demand for our products, fail to accurately forecast the timing of such demand, or are unable to consistently negotiate acceptable purchase order terms with customers, we could incur significant expenses, and our business, financial condition, results of operations and growth prospects may be materially adversely affected.
If we fail to effectively manage our growth or, alternatively, our spending during downturns, our business could be disrupted, which could materially adversely affect our results of operations.
Growth in revenues, combined with the challenges of managing geographically dispersed operations, can place a significant strain on our management systems and resources, and our anticipated growth in future operations could continue
S-9

to place such a strain. The failure to effectively manage our growth could disrupt our business and materially adversely affect our results of operations. Our ability to successfully offer our products and implement our business plan in evolving markets requires an effective planning and management process. Even if executed successfully, our expansion may not deliver the anticipated increase in revenues and other benefits to compensate for the expenses incurred. This could materially adversely affect our business, financial condition, results of operations and growth prospects. In economic downturns, we must effectively manage our spending and operations to ensure that our competitive position during the downturn, as well as our future opportunities when the economy improves, remains intact. The failure to effectively manage our spending and operations could disrupt our business and materially adversely affect our results of operations.
We depend on internal production and outside single or limited-source suppliers for many of our key components and raw materials, and any interruption in the supply of these key components and raw materials could materially adversely affect our business, financial condition, results of operations and growth prospects.
We rely exclusively on our own production capabilities to manufacture certain of our key components, such as semiconductor lasers, specialty optical fibers and optical components. Certain of our components, such as our semiconductor lasers, which are manufactured at our Vancouver, Washington facility, and our active fibers, which are manufactured at our Lohja, Finland facility, rely on processes and equipment that cannot be easily moved or replaced. If our manufacturing activities were obstructed or hampered significantly at these, or our other facilities, it could take a considerable length of time, at an increased cost, for us to resume manufacturing, which could materially harm our business and results of operations.
Also, we purchase certain raw materials and components, which are key elements to manufacture our products, from single- or limited-source suppliers. We generally do not have guaranteed supply arrangements with our suppliers. Some of our suppliers are relatively small private companies that may discontinue their operations at any time and may be particularly susceptible to prevailing economic conditions. Some of our suppliers are also our competitors. Our key suppliers may not have the ability to increase their production in line with our customers’ demands. This can become acute during times of high growth in our customers’ businesses. As a result, we experienced, and may in the future experience, longer lead times or delays in fulfillment of our orders. Furthermore, other than our current suppliers, there may be a limited number of entities from which we could obtain these supplies. We do not anticipate that we would be able to purchase these materials that we require in a short period of time or at the same cost from other sources in commercial quantities or that have our required performance specifications. In addition, if quality issues arise with these outsourced materials and go undetected by us, the use of such defective materials in our products could compromise their quality and harm our reputation.
For certain long lead-time supplies or in order to lock in pricing, we may be obligated to place purchase orders which are not cancelable or otherwise assume liability for a large amount of the ordered supplies, which limits our ability to adjust down our inventory liability in the event of market downturns or other customer cancellations or rescheduling of their purchase orders for our products. Some of our products require designs and specifications which are at the cutting-edge of available technologies. Our and our customers’ designs and specifications frequently change to meet rapidly evolving market demands. Accordingly, certain of our products require components and supplies which may be technologically difficult and unpredictable to manufacture. These types of components may only be available by a single supplier. These characteristics place further pressure on the timely delivery of such components. Any interruption or delay in the supply of any of these components or materials, or the inability to obtain these components and materials from alternate sources at acceptable prices and within a reasonable amount of time, could materially adversely affect our ability to meet customer orders. If our suppliers face financial or other difficulties, do not maintain sufficient inventory on hand or if there are significant changes in demand for the components and materials we obtain from them, they could limit the availability of these components and materials to us. Any of the foregoing could materially adversely affect our business, financial condition, results of operations and growth prospects.
We depend on our OEM customers and system integrators to incorporate our products into their systems.
Our revenues depend in part on our ability to maintain existing and secure new OEM customers. Our revenues also depend in part upon the ability of our current and potential OEM customers and system integrators to incorporate our products into their systems, and to sell such systems successfully. The commercial success of these systems depends to a substantial degree on the efforts of these OEM customers and system integrators to develop and market products that incorporate our technologies. Relationships and experience with traditional laser makers, limited marketing resources, reluctance to invest in research and development and other factors affecting these OEM customers and third-party system integrators could have a substantial impact upon demand for our products, and in turn upon our revenues and financial
S-10

results. If OEM customers or integrators are not able to adapt existing tools or develop new systems to take advantage of the features and benefits of lasers, or if they perceive us to be an actual or potential competitor, then the opportunities to expand our revenues and increase our margins may be severely limited or delayed. In addition, some of our OEM customers are developing their own laser sources. If they are successful, this may reduce our revenues from these customers.
Our products could contain defects, which may reduce sales of those products, harm market acceptance of our high-performance laser products or result in claims against us.
The manufacture of our high-performance lasers involves highly complex and precise processes. Despite testing by us and our customers, errors have been found in our products and may be found in the future. In addition, some of our products are combined with products from other vendors, which may contain defects. As a result, should problems occur, it may be difficult to identify the source of the problem. Our products are typically sold with warranty provisions that require us to remedy deficiencies in quality or performance over a specified period of time at no cost to our customers. Reserves for estimated warranty claims are recorded during the period of sale. The determination of such reserves requires us to make estimates of failure rates and expected costs to repair or replace the products under warranty. We typically establish warranty reserves based on historical warranty costs for each product line. If actual return rates and/or repair and replacement costs differ significantly from our estimates, adjustments to cost of revenues may be required in future periods, which could materially adversely affect our results of operations. These defects may cause us to incur significant warranty, support and repair costs, incur additional costs related to a recall, divert the attention of our engineering personnel from our product development efforts and harm our relationships with our customers. These problems could result in, among other things, loss of revenues or a delay in revenue recognition, loss of market share, harm to our reputation or a delay or loss of market acceptance of our laser products. Defects, integration issues or other performance problems in our products could also result in personal injury or financial or other damages to our customers, which in turn could damage market acceptance of our products. Our customers could also seek damages from us for their losses. A product liability claim brought against us, even if unsuccessful, could be time-consuming and costly to defend, and could harm our reputation. We cannot assure investors that our product liability insurance would adequately protect our assets from the financial impact of defending a product liability claim. Any product liability claim brought against us, with or without merit, could increase our product liability insurance rates or prevent us from securing insurance coverage in the future.
A breach of our information technology and security systems could materially adversely affect our business.
We use information technology and security systems to maintain our facility’s physical security and to protect proprietary and confidential information, including that of our customers, suppliers and employees. Denial of service or other attacks on, or accidental or willful security breaches or other unauthorized access to our facilities or information systems, unauthorized access to or acquisition of personal information, confidential information or other data we process or maintain, or viruses, loggers, or other malfeasant code, including ransomware, in our data or software, could compromise this information and otherwise disrupt our operations. The consequences of such loss, possible misuse of our proprietary and confidential information, or operational disruptions could include, among other things, unfavorable publicity, damage to our reputation, difficulty marketing our products, customer allegations of breach-of-contract, claims and litigation by affected parties, investigations by and other proceedings involving governmental authorities and possible financial liabilities for damages, any of which could materially adversely affect our business, financial condition, reputation and relationships with customers and partners. We also rely on a number of third-party service providers to host, store or otherwise process information for us, or to provide other facilities or infrastructure that we make use of, including “cloud-based” providers of corporate infrastructure services relating to, among other things, human resources, electronic communication services and some financial functions, and we are therefore dependent on the security systems of these providers. Any security breaches or other unauthorized access to, or disruptions of, our service-providers’ systems or viruses, loggers or other malfeasant code in their data or software, or unauthorized access to or acquisition of any data they process or otherwise maintain for us could expose us to information loss, operational disruptions, and misappropriation of confidential information, and could have similar consequences to us as any incidents affecting our own systems or the data we process or maintain. We and our third parties face these threats from a variety of sources, including attacks from hackers, phishing and other forms of social engineering, and human error or employee or contractor malfeasance. Because the techniques used to obtain unauthorized access to or sabotage security systems change frequently and are often not recognized until after an attack, we and our third-party service providers may be unable to anticipate the techniques or implement adequate preventative measures, thereby exposing us to material adverse effects on our business, financial condition, results of operations and growth prospects. A security breach or other security incident impacting us or our third-party service providers could require a substantial level of financial resources to rectify and otherwise respond to, may be difficult to identify or address in a timely manner, and could result in claims, investigations, and inquires by private parties or governmental entities that may divert management’s
S-11

attention and require the expenditure of significant time and resources, and which may cause us to incur substantial fines, penalties, or other liability and related legal and other costs. Any actual or perceived security breach or other security incident may also harm our reputation and market position. Any of the foregoing matters could harm our operating results and financial condition.
We may not be able to recruit or retain qualified personnel.
We believe our ability to manage successfully and grow our business and to develop new products depends, in large part, on our ability to recruit and retain qualified employees, particularly highly skilled technical, sales, service, management, and key staff personnel. Competition for qualified resources is intense and other companies may have greater resources available to provide substantial inducements to lure key personnel away from us or to offer more competitive compensation packages to individuals we are trying to hire.
Our growth is dependent, in part, on the successful integration of acquired businesses.

We acquired Nutronics in 2019 and may pursue other strategic transactions in the future. We have limited experience executing acquisitions. Integrating an acquired company, business or technology may create unforeseen operating difficulties and expenditures. If we fail to successfully integrate our acquisitions, or the people or technologies associated with those acquisitions, into our company, the results of operations of the combined company could be adversely affected. Any integration process will require significant time and resources, require significant attention from management, and disrupt the ordinary functioning of our business, and we may not be able to manage the process successfully, which could adversely affect our business, results of operations, and financial condition. We may have to pay cash, incur debt, or issue equity securities to pay for any such acquisition, each of which could affect our financial condition or the value of our capital stock. The sale of equity to finance any such acquisitions could result in dilution to our stockholders. If we incur more debt, it would result in increased fixed obligations and could also subject us to covenants or other restrictions that would impede our ability to flexibly operate our business.
Risks Related to Our International Sales and Operations
Our inability to manage risks associated with our international customers and operations could materially adversely affect our business.
Our foreign operations and revenues are subject to a number of risks, including the impact of recessions and other economic conditions in economies outside the United States, unexpected changes in regulatory requirements, certification requirements, environmental regulations, reduced protection for intellectual property rights in some countries, potentially adverse tax consequences, political and economic instability, import/export regulations, tariffs and trade barriers, compliance with applicable United States and foreign anti-corruption laws, cultural and management differences, pandemic illness, reliance in some jurisdictions on third-party revenues from channel partners, preference for locally produced products, shipping, or other logistics complications, and longer accounts receivable collection periods. In particular, the economic, political, legal, and regulatory climate in China, both nationally and regionally, is fluid and unpredictable, and operating in China exposes us to economic, political and legal risks.
Our business could also be impacted by international conflicts, terrorist and military activity, civil unrest and pandemic illness, including COVID-19, which could cause a slowdown in customer orders, cause customer order cancellations or negatively impact availability of supplies or limit our ability to produce or timely service our installed base of products. Political, economic and monetary instability and changes in governmental regulations or policies, including trade tariffs and protectionism, could materially adversely affect both our ability to effectively operate our foreign offices and the ability of our foreign suppliers to supply us with required materials or services. Any interruption or delay in the supply of our required components, products, materials or services, or our inability to obtain these components, materials, products or services from alternate sources at acceptable prices and within a reasonable amount of time, could impair our ability to meet scheduled product deliveries to our customers and could cause customers to cancel orders.
Our failure to manage the foregoing risks associated with our existing and potential future international business operations could materially adversely affect our business, financial condition, results of operations and growth prospects.
Tariffs and global trade policies could increase the cost of our products, which could adversely impact the competitiveness of our products and our financial results.
S-12

Tariffs may materially increase the cost of our raw materials and finished goods, and may negatively impact our margins as we may not be able to pass on the additional cost through increasing the prices of our products. Tariffs may cause a contraction of certain industries, including the Industrial market. As such, there may be potential decrease in the spending powers of our customers, which may lead to fewer business opportunities and our operation may be negatively impacted.
We are exposed to foreign currency risk, which may materially adversely affect our revenues, cost of revenues and operating margins and could result in exchange losses.
Our international operations are significant to our revenues and net income. While we report our financial results in U.S. dollars, we incur certain costs in other currencies, and have certain foreign currency denominated assets and liabilities. We, therefore, face exposure to fluctuations in currency exchange rates. Significant fluctuations in exchange rates between the U.S. dollar and foreign currencies may adversely affect our revenues and earnings.
Risks Related to Litigation, Taxation and Regulatory Compliance
Our agreements with the U.S. government and suppliers to the U.S. government subject us to unique risks.
We must comply with and are affected by laws and regulations relating to the award, administration, and performance of U.S. government contracts. Awards received from the U.S. government may be cancelled or lose funding. The U.S. government contracting party may require us to increase or decrease production of certain solutions sold to the U.S. government due to changes in U.S. national security strategy and/or priorities or other reasons, which could impact production of other products or sales to other customers to meet the requirements of the U.S. government. In addition, the U.S. government routinely retains rights to intellectual property developed in connection with a government contract. The U.S. government could exercise these rights in certain circumstances in the future, which could have the effect of decreasing the benefit we are able to realize commercially from such intellectual property.
U.S. government agencies routinely audit and investigate government contractors and can decrease or withhold certain payments when it deems systems subject to its review to be inadequate. Additionally, any costs found to be misclassified may be subject to repayment. We have unaudited and unsettled incurred cost claims related to past years, which places risk on our ability to issue final billings on contracts for which authorized and appropriated funds may be expiring. If an audit or investigation uncovers improper or illegal activities, we may be subject to civil or criminal penalties and administrative sanctions, including reductions of the value of contracts, contract modifications or terminations, forfeiture of profits, suspension of payments, penalties, fines and suspension, or prohibition from doing business with the U.S. government. In addition, we could suffer serious reputational harm if allegations of impropriety were made against us. Similar government oversight exists in most other countries where we conduct business. Any such imposition of penalties, or the loss of such government contracts, could materially adversely affect our business, financial condition, results of operations and growth prospects.
We are subject to governmental export and import controls that could subject us to liability or impair our ability to compete in international markets.
The U.S. and various foreign governments have imposed controls, export license requirements and restrictions on the import or export of certain products, technologies, and software. We must export our products in compliance with U.S. export controls and we may not always be successful in obtaining necessary export licenses. Our failure to obtain required import or export approval for our products or limitations on our ability to export or sell our products imposed by these laws may harm our international and domestic revenues. Noncompliance with these laws could have negative consequences, including government investigations, penalties and reputational harm. In addition, compliance with the directives of the Directorate of Defense Trade Controls, or DDTC, may result in substantial expenses and diversion of management attention. Any failure to adequately address the directives of DDTC could result in civil fines or suspension or loss of our export privileges, any of which could materially adversely affect our business, financial condition, results of operations and growth prospects.
Changes in our products or changes in export, import and economic sanctions laws and regulations may delay our introduction of new products in international markets, prevent our customers from deploying our products internationally or, in some cases, prevent the export or import of our products to or from certain countries altogether. In addition to the tariffs imposed by the U.S. Government on certain items imported from China, it is possible that additional sanctions or restrictions may be imposed by the United States on items imported into the United States from China. Similarly, in addition to the tariffs imposed by China on certain items imported from the United States, it is possible that additional sanctions or restrictions may
S-13

be imposed by China on items imported into China from the United States. Any such measures could further adversely affect our ability to sell our products to existing or potential customers and harm our ability to compete internationally and grow our business. Any change in export or import regulations or legislation, shift or change in enforcement, or change in the countries, persons or technologies targeted by these regulations, could result in decreased use of our products by, or in our decreased ability to export or sell our products to, existing or potential customers with international operations. In such event, our business, financial condition, results of operations and growth prospects could be materially adversely affected.
We are subject to anti-corruption, anti-bribery, anti-money laundering and similar laws, and non-compliance with such laws can subject us to criminal penalties or significant fines and harm our business and reputation.
We are subject to anti-corruption and anti-bribery and similar laws. Anti-corruption and anti-bribery laws have been enforced aggressively in recent years and are interpreted broadly and prohibit companies and their employees and agents from promising, authorizing, making, offering, soliciting or accepting improper payments or other benefits to or from government officials and others in the public and private sectors. We can be held liable for the corrupt or other illegal activities of our employees, representatives, contractors, business partners and agents, even if we do not explicitly authorize or have actual knowledge of such activities. Our operations and sales in China, India, Brazil, the Middle East, and other countries create the risk of unauthorized payments or offers of payments by our employees, consultants, sales agents or distributors, even though they may not always be subject to our control.
These laws also require that we keep accurate books and records and maintain internal controls and compliance procedures designed to prevent any such actions. While we have policies and procedures to address compliance with these laws, we cannot assure you that our employees, representatives, contractors, business partners and agents will not take actions that violate our policies or applicable law, for which we can be held liable.
Noncompliance with these laws could subject us to investigations, sanctions, settlements, prosecution, other enforcement actions, disgorgement of profits, significant fines, damages, other civil and criminal penalties or injunctions, suspension or debarment from contracting with certain persons, the loss of export privileges, whistleblower complaints, reputational harm, adverse media coverage and other collateral consequences. If any subpoenas or investigations are launched, or governmental or other sanctions are imposed, or if we do not prevail in any possible civil or criminal litigation, our business, financial condition, results of operations and growth prospects could be materially adversely affected. In addition, responding to any action will likely result in a materially significant diversion of management’s attention and resources and significant defense and compliance costs and other professional fees.
We could be subject to additional income tax liabilities.
Our tax liability, after-tax profitability and effective tax rate in a given financial statement period may be materially impacted by changes in tax laws, including legislation implementing changes in taxation of international business activities, changes in the mix and level of earnings by taxing jurisdictions or changes to existing accounting rules or regulations. There are numerous other factors that could affect our tax rate, including, among others, intercompany transactions, losses incurred in jurisdictions for which we are not able to realize the related tax benefits, and entry into new businesses and geographies. Fluctuations in our tax obligations and effective tax rate could adversely affect our business, financial condition and operating results.
We are subject to income taxes in the United States and certain other foreign jurisdictions. Judgment is required in evaluating our worldwide provision for income taxes. During the ordinary course of business, there are many transactions for which the ultimate tax determination is uncertain. For example, our effective tax rates could be adversely affected by earnings being lower than anticipated in countries where we have lower statutory rates and higher than anticipated in countries where we have higher statutory rates, by changes in foreign currency exchange rates, by changes in the valuation of our deferred tax assets and liabilities, or by changes in the relevant tax, accounting and other laws, regulations, principles and interpretations. We are subject to audit in various jurisdictions, and such jurisdictions may assess additional income tax against us. The final determination of tax audits and any related litigation could be materially different from our historical income tax provisions and accruals. The results of an audit or litigation could have a material adverse effect on our operating results or cash flows in the period or periods for which that determination is made.
Our intercompany relationships are subject to complex transfer pricing regulations administered by taxing authorities in various jurisdictions. If relevant taxing authorities were to disagree with our determinations as to the income and expenses attributable to specific jurisdictions, and our position was not sustained, we could be required to pay additional taxes, interest
S-14

and penalties, which could result in one-time tax charges, higher effective tax rates, reduced cash flows and lower overall profitability of our operations. There can be no assurances that our reserves would be adequate to cover such a contingency.
We are subject to various environmental laws and regulations that could impose substantial costs upon us and may materially adversely affect our business, financial condition, results of operations and growth prospects.
We are subject to a variety of federal, state, local and foreign environmental regulations relating to the use, storage, discharge and disposal of hazardous chemicals used during our manufacturing process or requiring design changes or recycling of products we manufacture. We could incur costs, fines and civil or criminal sanctions, third-party property damage or personal injury claims, or could be required to incur substantial investigation or remediation costs, if we were to violate or become liable under environmental laws. Compliance with current or future environmental laws and regulations could restrict our ability to expand our facilities or require us to acquire additional expensive equipment, modify our manufacturing processes or incur other significant expenses in order to remain in compliance with such laws and regulations.
Privacy and data security concerns, and data collection and transfer restrictions and related domestic or foreign regulations may limit the use and adoption of our solutions and adversely affect our business.
Personal privacy, information security and data protection are significant issues in the United States, Europe and many other jurisdictions where we have operations or offer our products. The regulatory framework governing the collection, use, and other processing of personal data and other information is rapidly evolving. The United States federal and various state and foreign governments have adopted or proposed requirements regarding the collection, distribution, use, security and storage of personally identifiable information and other data relating to individuals, and federal and state consumer protection laws are being applied to enforce regulations related to the online collection, use and dissemination of data.
Further, many foreign countries and governmental bodies, including the European Union (EU) and China, have laws and regulations concerning the collection and use of personal data obtained from their residents or by businesses operating within their jurisdiction, or relating to cybersecurity. These laws and regulations often are more restrictive than those in the United States. We also expect that there will continue to be new proposed laws, regulations and industry standards concerning privacy, data protection and information security in the United States, the EU and other jurisdictions. We cannot yet fully determine the impact these or future laws, regulations and standards may have on our business, but these laws, regulations and standards often are subject to differing interpretations, may be inconsistent among jurisdictions, and may be alleged to be inconsistent with our current or future practices. We also may be bound by contractual or other obligations applicable to our collection, use, processing, security and disclosure of various types of data. These and other requirements could increase our costs, impair our ability to grow our business, or restrict our ability to store and process data, and may subject us to liability.
The costs of compliance with and other burdens imposed by laws, regulations, standards and other actual or asserted obligations relating to privacy, data protection and information security may be substantial, and they may require us to modify our data processing practices and policies. Any actual or alleged noncompliance with any of these laws, regulations, standards, and other actual or asserted obligations may lead to claims and proceedings by governmental actors and private parties, and significant fines, penalties or liabilities.
Results of future litigation could materially adversely affect our business, financial condition, results of operations and growth prospects.
From time to time, we have been subject to litigation. The outcome of any litigation, regardless of its merits, is inherently uncertain. Future litigation could result in significant damages payable by us, and could harm our reputation. Even if we are successful in our defense, such litigation could still result in a diversion of management’s attention and our resources and we may be required to incur significant expenses defending against these claims. We cannot predict our future commitments with respect to any matters encountered in the future, or their eventual outcome. Because of uncertainties relating to litigation, the amount of our liability estimates could be wrong. Any adverse determination related to litigation could require us to change our technology or our business practices, pay monetary damages or fines, or enter into royalty or licensing arrangements, which could materially adversely affect our cash flows, harm our reputation, or otherwise materially adversely affect our business, financial condition, results of operations and growth prospects.
If we are unable to protect our proprietary technology and intellectual property rights, our competitive position could be harmed and our results of operations could be materially adversely affected.
S-15

We rely on a variety of intellectual property rights, including patents, trademarks, trade secrets, technical know-how and other unpatented proprietary information to protect our technologies, products, product development and manufacturing activities from unauthorized use by third parties. Our patents do not cover all of our technologies, systems, products and product components and our competitors or others may design around our patented technologies. We cannot guarantee we have entered into appropriate agreements with all parties that have had access to our trade secrets, know-how or other proprietary information to adequately protect all such information. We also cannot assure you that those agreements will provide meaningful protection for our trade secrets, know-how or other proprietary information in the event of any unauthorized use or disclosure. Our trade secrets, know-how or other proprietary information could be obtained by third parties as a result of breaches of our physical or electronic security systems or our suppliers, employees or consultants could assert rights to our intellectual property.
We have significant international operations and we are subject to foreign laws which differ in many respects from U.S. laws. Effective intellectual property protection may be unavailable or more limited in foreign jurisdictions in which we operate, such as China, relative to those protections available in the United States. Furthermore, any changes in, or unexpected interpretations of, the trade secret and other intellectual property laws in any country in which we operate may materially adversely affect our ability to enforce our trade secret and intellectual property positions. In the past, certain of our employees have been hired by our competitors. While these former employees are contractually prohibited from misappropriating our proprietary rights, we cannot be certain that such contractual obligations will be honored. If we detect misappropriation and decide to enforce such contractual obligations and pursue litigation to assert our intellectual property rights, an adverse decision in any legal action could limit our ability to assert our intellectual property rights, limit the value of our technology or otherwise materially adversely affect our business, financial condition or results of operations.
Monitoring unauthorized use of our intellectual property is difficult and costly. Unauthorized use of our intellectual property may have already occurred or may occur in the future. Our failure to identify unauthorized use or otherwise adequately protect our intellectual property could jeopardize our competitive advantage and materially adversely affect our business. Moreover, any litigation in connection with unauthorized use of our intellectual property could be time consuming, and we could be forced to incur significant costs and divert our attention and the efforts of our employees, which could, in turn, result in lower revenues and higher expenses, and we may not be successful in enforcing our intellectual property rights.
Intellectual property claims could result in costly litigation and harm our business.
There has been significant litigation involving intellectual property rights in many technology-driven industries, including our own. We continue to face risks and uncertainties in connection with any patent litigation, including the risk that patents issued to others may restrict and harm our ability to do business; that there could be existing patents or pending applications of which we are unaware that may later result in issued patents upon which our product may infringe. Moreover, the frequency with which new patents are granted and the diversity of jurisdictions in which they are granted make it impractical and expensive for us to monitor all patents that may be relevant to our business. We may also become involved in the defense and prosecution of intellectual property suits, patent interferences, opposition proceedings and other administrative proceedings.
From time to time, we have been notified of allegations and claims that we may be infringing patents or otherwise violating intellectual property rights owned by third parties. In the future, we may be a party to litigation because of an alleged infringement, misappropriation, or other violation of others’ intellectual property, whether through direct claims or by way of indemnification claims of our customers or suppliers. If any pending or future intellectual property-related litigation proceedings result in an adverse outcome, then we could be required to:
•cease the manufacture, use or sale of the infringing products, processes, or technology;
•pay substantial damages for infringement;
•expend significant resources to develop non-infringing products, processes, or technology;
•license technology from the party claiming infringement, which license may not be available on commercially reasonable terms, or at all;
•cross-license our technology to a competitor or commit to covenant-not-to-sue to resolve an infringement claim, which could weaken our ability to compete with that competitor; or
•pay substantial damages to our direct or indirect customers to cause our end users to discontinue their use of, or replace, infringing products with non-infringing products.
S-16

In addition, intellectual property lawsuits can be brought by third parties against our customers and end-users that incorporate our products into their systems or processes. Because we generally indemnify customers against third-party infringement claims relating to our products, we may incur liabilities in connection with lawsuits against our customers. Any such lawsuits could be time-and-resources-consuming to defend, damage our reputation and result in substantial and unanticipated costs. Having to defend any such lawsuits, and any adverse consequences that might arise, could materially adversely affect our business, financial condition, results of operations and growth prospects.
Our ability to use net operating loss carryforwards to offset future taxable income may be limited.
We have U.S. federal and state net operating loss carryforwards (NOLs) and research development credit carryforwards which we may use to reduce future taxable income or offset income taxes due. Some of the NOLs and credit carryforwards start expiring in 2021 and others will start expiring in 2023. Insufficient future taxable income will adversely affect our ability to deploy these NOLs and credit carryforwards. Our ability to utilize these NOLs and credit carryforwards may also be affected by recent tax legislation such as the 2017 Tax Cuts and Jobs Act, as modified by the Coronavirus Aid, Relief, and Economic Security Act, which allows federal NOLs incurred in tax years beginning after December 31, 2017 to be carried forward indefinitely, but limits use of such federal NOLs in tax years beginning after December 31, 2020 to 80% of taxable income. In addition, under Section 382 of the U.S. Internal Revenue Code, or the Code, a corporation that experiences a more than 50% ownership change over a three-year testing period is limited in its ability to use its pre-change NOLs and other tax assets to offset future taxable income or income taxes due. Our existing NOLs and credit carryforwards are subject to limitations arising from previous ownership changes. Our ability to use our NOLs and credit carryforwards could be further limited by Section 382 of the Code if we undergo an ownership change. Future changes in our stock ownership, the causes of which may be outside our control, could result in an ownership change under Section 382 of the Code. Our NOLs may also be impaired under state law. As a result of these limitations, we may not be able to utilize a material portion of, or possibly any of, the NOLs and credit carryforwards, which could materially adversely affect our cash flows.
Risks Related to Ownership of Our Common Stock and this Offering
Fluctuations in our quarterly results of operations may increase the volatility of our stock price and may be difficult to predict.
We have experienced, and expect to continue to experience, fluctuations in our quarterly results of operations. We believe that fluctuations in quarterly results may cause the market price of our common stock to increase or decrease, perhaps substantially. Factors which have had or may in the future have an influence on our results of operations in a particular quarter include:
•the increase, decrease, cancellation or rescheduling of significant customer orders;
•declines in selling prices for our products;
•the impact of the COVID-19 pandemic and other public health crises, including on macroeconomic conditions and our business, results of operations and financial condition;
•government-mandated quarantines or closures applicable to our facilities or the facilities of our customers or suppliers;
•delays in our product-shipment timing, obtaining licenses or other import/export approvals, customer or end-user sales or deployment cycles, or work performed under development contracts;
•seasonality attributable to different purchasing patterns and levels of activity throughout the year in the areas where we operate;
•the impact of new acquisitions and the success of our integration efforts;
•the timing of revenue recognition based on the installation or acceptance of certain products shipped to our customers;
•timing variability in product introductions, enhancements, services and technologies by us and our competitors and market acceptance of these new or enhanced products, services and technologies;
•different capital expenditure and budget cycles for our customers, which affect the timing of their spending;
•our ability to obtain export licenses for our products on a timely basis or at all;
•changes in tariffs imposed by the U.S., China and other foreign governments;
•the rate at which our present and future customers and end users adopt our technologies;
•the gain or loss of a key customer;
•product or customer mix;
•competitive pricing pressures and new market entrants;
S-17

•our ability to design, manufacture and introduce new products on a cost-effective and timely basis;
•our ability to manage our inventory levels and any write-downs for excess or obsolete inventory;
•our ability to collect outstanding accounts receivable balances;
•changes in the amount and timing of our operating costs, including those related to the expansion of our business, operations and infrastructure;
•impairment of values for goodwill, intangibles and other long-lived assets;
•foreign currency fluctuations;
•changes in jurisdictional income mix and tax rules and regulations in countries where we operate; and
•economic and market conditions in a particular geography or country.
A substantial portion of our operating expenses are fixed for the short-term, and as a result, fluctuations in revenues or unanticipated expenses can have a material and immediate impact on our profitability. In addition, we often recognize a substantial portion of our revenues in the last month of each fiscal quarter. Our expenses for any given quarter are typically based on expected revenues, and if revenues are below expectations in any given quarter, the adverse impact of the shortfall on our results of operations may be magnified by our inability to adjust spending quickly enough to compensate for the shortfall. We also base our manufacturing on our forecasted product mix for the quarter. If the actual product mix varies significantly from our forecast, we may not be able to fill some orders during that quarter, which would result in delays in the shipment of our products. Accordingly, variations in timing of sales, particularly for our higher priced, higher margin products, can cause significant fluctuations in quarterly results of operations.
Due to these and other factors, particularly varying product mix from quarter to quarter, we believe that quarter-to-quarter and year-to-year comparisons of our historical results of operations may not be meaningful. You should not rely on our results for any quarter or year as an indication of our future performance.
The market price of our common stock may be volatile, and the value of your investment could decline significantly.
Technology stocks have historically experienced high levels of volatility. The trading price of our common stock has been and is likely to continue to be volatile. Factors that could cause fluctuations in the trading price of our common stock include the following:
•the impact of the COVID-19 pandemic and other public health crises, including on macroeconomic conditions and our business, results of operations and financial condition;
•price and volume fluctuations in the overall stock market from time to time;
•changes in operating performance, stock market valuations and volatility in the market prices of other technology companies generally, or those in our industry in particular;
•actual or anticipated quarterly variations in our results of operations or those of our competitors;
•actual or anticipated changes in our growth rate relative to our competitors;
•announcements by us or our competitors of acquisitions, new products, significant contracts, commercial relationships or capital commitments;
•manufacturing or supply interruptions;
•developments with respect to intellectual property rights;
•our ability to develop and market new and enhanced products on a timely basis;
•commencement of, or our involvement in, litigation;
•major changes in our Board of Directors or management;
•changes in governmental regulations or in the status of our regulatory approvals;
•actual or perceived privacy, data protection or cybersecurity breaches or incidents;
•the trading volume of our stock;
•any future sales or repurchases of our common stock or other securities;
•failure of financial analysts to maintain coverage of us, changes in financial estimates by any analysts who follow our company or our failure to meet these estimates or the expectations of investors;
•fluctuations in the values of companies perceived by investors to be comparable to us;
•the financial projections we may provide to the public, any changes in these projections or our failure to meet these projections; and
•general economic conditions and slow or negative growth of related markets.
The stock market in general, and market prices for the securities of technology companies like ours in particular, have from time to time experienced volatility that often has been unrelated to the operating performance of the underlying
S-18

companies. These broad market and industry fluctuations may adversely affect the market price of our common stock, regardless of our operating performance. In several recent situations when the market price of a stock has been volatile, holders of that stock have instituted securities class action litigation against the company that issued the stock. If any of our stockholders were to bring a lawsuit against us, the defense and disposition of the lawsuit could be costly and divert the time and attention of our management and materially adversely affect our results of operations.
Future sales of our common stock could cause our stock price to fall.
Our stock price could decline as a result of sales of a large number of shares of our common stock or the perception that these sales could occur. These sales, or the possibility that these sales may occur, also might make it more difficult for us to sell equity securities in the future at a time and at a price that we deem appropriate.
Delaware and Washington law and provisions in our amended and restated certificate of incorporation and amended and restated bylaws could make a merger, tender offer or proxy contest difficult, thereby depressing the trading price of our common stock.
Provisions of our amended and restated certificate of incorporation and amended and restated bylaws may delay or discourage transactions involving an actual or potential change in our control or change in our management, including transactions in which stockholders might otherwise receive a premium for their shares, or transactions that our stockholders might otherwise deem to be in their best interests. Therefore, these provisions could adversely affect the price of our stock. Among other things, our amended and restated certificate of incorporation and amended and restated bylaws:
•permit the Board of Directors to issue up to 5 million shares of preferred stock, with any rights, preferences and privileges as they may designate;
•provide that the authorized number of directors may be changed only by resolution of the Board of Directors;
•provide that all vacancies on our Board of Directors may only be filled by our Board of Directors and not by stockholders;
•divide the Board of Directors into three classes;
•provide that a director may only be removed from the Board of Directors by the stockholders for cause;
•require that any action to be taken by our stockholders must be effected at a duly called annual or special meeting of stockholders and may not be taken by written consent;
•provide that stockholders seeking to present proposals before a meeting of stockholders or to nominate candidates for election as directors at a meeting of stockholders must provide notice in writing in a timely manner and meet specific requirements as to the form and content of a stockholder’s notice;
•prevent cumulative voting rights (therefore allowing the holders of a plurality of the shares of common stock entitled to vote in any election of directors to elect all of the directors standing for election, if they should so choose);
•provide that special meetings of our stockholders may be called only by the chairman of the board, our chief executive officer (or president, in the absence of a chief executive officer) or by the Board of Directors; and
•provide that stockholders will be permitted to amend our amended and restated certificate of incorporation and our amended and restated bylaws only upon receiving at least two-thirds of the total votes entitled to be cast by holders of all outstanding shares then entitled to vote generally in the election of directors, voting together as a single class.
In addition, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, which generally prohibits a Delaware corporation from engaging in any of a broad range of business combinations with any “interested” stockholder for a period of three years following the date on which the stockholder became an “interested” stockholder. Likewise, because our principal executive offices are located in Washington, the anti-takeover provisions of the Washington Business Corporation Act may apply to us under certain circumstances now or in the future. These provisions prohibit a “target corporation” from engaging in any of a broad range of business combinations with any stockholder constituting an “acquiring person” for a period of five years following the date on which the stockholder became an “acquiring person.”
Our bylaws designate a state or federal court located within the State of Delaware as the exclusive forum for substantially all disputes between us and our stockholders, and also provide that the federal district courts are the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act, each of which could limit our stockholders’ ability to choose the judicial forum for disputes with us or our directors, officers, stockholders or employees.
S-19

Our amended and restated bylaws provide that, unless we consent in writing to the selection of an alternative forum, the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers, or other employees to us or our stockholders, (iii) any action arising pursuant to any provision of the Delaware General Corporation Law, or our amended and restated certificate of incorporation or our amended and restated bylaws or (iv) any other action asserting a claim that is governed by the internal affairs doctrine shall be a state or federal court located within the State of Delaware, in all cases subject to the court having jurisdiction over indispensable parties named as defendants. Our amended and restated bylaws also provide that the federal district courts of the United States of America are the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act. These exclusive-forum provisions may limit a stockholder’s ability to bring a claim in a judicial forum of its choosing for disputes with us or our directors, officers, or other employees, which may discourage lawsuits against us and our directors, officers, and other employees. If a court were to find either exclusive-forum provision in our amended and restated bylaws to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving the dispute in other jurisdictions, which could harm our results of operations.
We have broad discretion to use the net proceeds from this offering, and our investment of these proceeds may not yield a favorable return. We may invest the proceeds of this offering in ways you disagree with.
Our management has broad discretion as to how to spend and invest the proceeds from this offering, and we may spend or invest these proceeds in ways with which our stockholders may disagree. Accordingly, investors will need to rely on our judgment with respect to the use of these proceeds. We intend to use the proceeds from this offering for working capital, capital expenditures and other general corporate purposes. We may also use a portion of our net proceeds to fund potential acquisitions of, or investments in, technologies or businesses that complement our business, although we have no present commitments or agreements to enter into any such acquisitions or make any such investments. We could spend the proceeds from this offering in ways that our stockholders may not agree with or that do not yield a favorable return. You will not have the opportunity as part of your investment decision to assess whether the net proceeds are being used appropriately. If we do not use the net proceeds that we receive in this offering effectively, our business, financial condition, results of operations and growth prospects could be materially adversely affected, and the market price of our common stock could decline.

USE OF PROCEEDS
We estimate that the net proceeds from our sale of shares of common stock in this offering will be approximately $             million (or approximately $          million if the underwriters exercise their option to purchase additional shares in full), after deducting underwriting discounts and commissions and estimated offering expenses payable by us.

We intend to use the net proceeds from this offering for working capital, capital expenditures and other general corporate purposes. We may also use a portion of our net proceeds to fund potential acquisitions of, or investments in, technologies or businesses that complement our business, although we have no present commitments or agreements to enter into any such acquisitions or make any such investments.
The expected use of net proceeds of this offering represents our current intentions based upon our present plans and business conditions. We cannot specify with certainty all of the particular uses for the net proceeds to be received upon the closing of this offering. Pending such uses, we plan to invest the net proceeds of this offering in short and intermediate-term, interest-bearing obligations, investment-grade instruments, certificates of deposit or direct or guaranteed obligations of the U.S. government.

S-23

DIVIDEND POLICY
We have never declared or paid any cash dividends on our common stock or any other securities. We anticipate that we will retain all available funds and any future earnings, if any, for use in the operation of our business and do not anticipate paying cash dividends in the foreseeable future. In addition, our credit facilities materially restrict, and future debt instruments may materially restrict, our ability to pay dividends on our common stock. Payment of future cash dividends, if any, will be at the discretion of our board of directors after taking into account various factors, including our financial condition, operating results, current and anticipated cash needs, the requirements of our current or then-existing debt instruments and other factors our board of directors deems relevant.

S-24

DILUTION
If you invest in our common stock, you will experience immediate and substantial dilution in the net tangible book value of your shares of common stock. Dilution in net tangible book value represents the difference between the price to public per share of our common stock and the as adjusted net tangible book value per share, as adjusted to give effect to this offering.
Net tangible book value represents our total tangible assets less total liabilities, divided by the number of shares of common stock outstanding as of December 31, 2020. Our net tangible book value as of December 31, 2020 was $186.8 million, or $4.69 per share. After giving effect to the sale and issuance by us of           shares of our common stock in this offering at the public offering price of $        per share, and after deducting underwriting discounts and commissions and estimated offering expenses payable by us, our as adjusted net tangible book value as of December 31, 2020 would have been approximately $         million, or $      per share. This represents an immediate increase in net tangible book value of $       per share to existing stockholders and an immediate dilution of $       per share to new investors purchasing common stock in this offering.
The following table illustrates this dilution on a per share basis to new investors:
Public offering price per share 
Net tangible book value per share as of December 31, 2020$4.69 
Increase in net tangible book value per share attributable to investors participating in the offering 
As adjusted net tangible book value per share, as adjusted to give effect to this offering 
Dilution in as adjusted net tangible book value per share to investors participating in this offering 

If the underwriters exercise in full their option to purchase              shares of our common stock in this offering at the public offering price of $       per share, the as adjusted net tangible book value per share after the offering would be $ per share, the increase in the net tangible book value per share to existing stockholders would be $       per share, and the dilution to new investors purchasing common stock in this offering would be $      per share.

The number of shares of our common stock outstanding immediately after this offering is based on 39,793,215 shares of our common stock outstanding as of December 31, 2020, and excludes:
•    3,357,968 shares of common stock issuable upon the exercise of options to purchase shares of our common stock outstanding as of December 31, 2020, with a weighted-average exercise price of $1.53 per share;
•    2,799,995 shares of common stock issuable upon the settlement of RSUs outstanding as of December 31, 2020; and
•    8,004,474 shares of common reserved for future issuance under our stock-based compensation plans, consisting of: 5,016,001 shares of common stock reserved for future issuance under our 2018 Plan, and any additional shares that become available under our 2018 Plan pursuant to provisions thereof, including provisions that automatically increase the share reserve under the plan each year; and 2,988,473 shares of common stock reserved for future issuance under our ESPP, and any additional shares that become available under our ESPP pursuant to provisions thereof, including provisions that automatically increase the share reserve under the plan each year.
To the extent that any of our outstanding stock options are exercised or RSUs or RSAs vest, we grant additional stock options or other awards under our stock-based compensation plans, or we issue additional shares of common stock in the future, you will experience further dilution.

MATERIAL U.S. FEDERAL INCOME AND ESTATE TAX CONSEQUENCES
FOR NON-U.S. HOLDERS OF COMMON STOCK
The following is a summary of the material U.S. federal income tax consequences to non-U.S. holders (as defined below) of the ownership and disposition of our common stock, but does not purport to be a complete analysis of all the potential tax considerations relating thereto. This summary is based upon the provisions of the Code, U.S. Treasury Regulations promulgated thereunder, administrative rulings and judicial decisions, all as of the date hereof, all of which are subject to change, possibly with retroactive effect, which could result in U.S. federal income tax consequences different than those summarized below. We have not sought a ruling from the Internal Revenue Service, or IRS, with respect to the statements made and the conclusions reached in the following summary, and there can be no assurance that the IRS will agree with such statements and conclusions.
This summary does not address the potential application of the U.S. federal tax on net investment income, the tax considerations arising under the laws of any state, local or other jurisdiction, or U.S. federal estate, gift or generation-skipping tax, except to the extent provided below. This summary is limited to investors who will hold our common stock as a capital asset for tax purposes. This summary does not address all tax considerations that may be important to a particular investor in light of the investor’s circumstances or to certain categories of non-U.S. investors that may be subject to special rules, including, without limitation:
•banks, insurance companies or other financial institutions (except to the extent specifically set forth below);

•tax-exempt organizations;

•controlled foreign corporations, passive foreign investment companies and corporations that accumulate earnings to avoid U.S. federal income tax;

•dealers in securities or currencies;

•traders in securities that elect to use a mark-to-market method of accounting for their securities holdings;

•persons that own, or are deemed to own, more than 5% of our capital stock (except to the extent specifically set forth below);

•U.S. expatriates, certain former citizens or long-term residents of the United States;

•persons who hold our common stock as a position in a hedging transaction, “straddle,” “conversion transaction” or other risk reduction transaction; or

•persons deemed to sell our common stock under the constructive sale provisions of the Code.
In addition, if a partnership (including any entity classified as a partnership for U.S. federal income tax purposes) holds our common stock, the tax treatment of a partner generally will depend on the status of the partner and upon the activities of the partnership. Therefore, this summary does not address tax considerations applicable to partnerships that hold our common stock. Accordingly, partnerships that hold our common stock and partners in such partnerships should consult their tax advisors.
You are urged to consult your tax advisor with respect to the application of the U.S. federal income tax laws to your particular situation, as well as any tax consequences of the purchase, ownership and disposition of our common stock arising under the U.S. federal estate, gift, and generation-skipping tax rules or under the tax laws of any state, local, non-U.S. or other taxing jurisdiction or under any applicable tax treaty.
Non-U.S. Holder Defined
For purposes of this discussion, you are a non-U.S. holder if you are a beneficial owner of our common stock, other than a partnership that is not: (i) an individual who is a citizen or resident of the United States; (ii) a corporation or other entity
S-26

taxable as a corporation for U.S. federal income tax purposes that was created or organized in or under the laws of the United States, any state thereof or the District of Columbia; (iii) an estate whose income is subject to U.S. federal income taxation regardless of its source; or (iv) a trust that either is subject to the supervision of a court within the United States and has one or more U.S. persons with authority to control all of its substantial decisions, or has a valid election in effect under applicable U.S. Treasury Regulations to be treated as a U.S. person.
If you are a non-U.S. citizen individual, you may, in many cases, be deemed to be a resident alien, as opposed to a nonresident alien, by virtue of being present in the United States for at least 31 days in the calendar year and for an aggregate of at least 183 days during a three-year period ending in the current calendar year. For these purposes, all the days present in the current year, one-third of the days present in the immediately preceding year, and one-sixth of the days present in the second preceding year are counted. Resident aliens are subject to U.S. federal income tax as if they were U.S. citizens. Such an individual is urged to consult his or her own tax advisor regarding the U.S. federal income tax consequences of the acquisition, ownership and disposition of our common stock.
Distributions on Common Stock
If we make distributions on our common stock, these distributions generally will constitute dividends for U.S. tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. To the extent these distributions exceed both our current and our accumulated earnings and profits, they will constitute a return of capital and will first reduce your basis in our common stock, but not below zero, and then will be treated as gain from the sale of stock.
Subject to the discussion below regarding withholding on foreign accounts, any dividend paid to you generally will be subject to U.S. withholding either at a rate of 30% of the gross amount of the dividend or such lower rate as may be specified by an applicable income tax treaty. In order to receive a reduced treaty rate, you must provide us with an IRS Form W-8BEN or W-8BEN-E or other appropriate version of IRS Form W-8 certifying qualification for the reduced rate. If you are eligible for a reduced rate of withholding pursuant to an income tax treaty, you may obtain a refund of any excess amounts withheld by filing an appropriate claim for refund with the IRS. If you hold our common stock through a financial institution or other agent acting on your behalf, you will be required to provide appropriate documentation to the agent, which then will be required to provide certification to us or our paying agent, either directly or through other intermediaries.
Dividends received by you that are effectively connected with your conduct of a U.S. trade or business (and, if an income tax treaty applies, attributable to a permanent establishment maintained by you in the United States) are exempt from withholding. In order to claim this exemption, you must provide us with an IRS Form W-8ECI or other applicable IRS Form W-8 properly certifying exemption. Such effectively connected dividends, although not subject to withholding, are taxed at the same U.S. federal income tax rates applicable to U.S. persons, net of certain deductions and credits. In addition, if you are a corporate non-U.S. holder, dividends you receive that are effectively connected with your conduct of a U.S. trade or business may also be subject to a branch profits tax at a rate of 30% or such lower rate as may be specified by an applicable income tax treaty.
Gain on Disposition of Common Stock
Subject to the discussion below regarding withholding on foreign accounts, a non-U.S. holder generally will not be subject to U.S. federal income tax on any gain realized upon the sale or other disposition of our common stock unless:
•the gain is effectively connected with your conduct of a U.S. trade or business (and, if an income tax treaty applies, the gain is attributable to a permanent establishment maintained by you in the U.S.);
•you are an individual who is present in the U.S. for a period or periods aggregating 183 days or more during the calendar year in which the sale or disposition occurs and certain other conditions are met; or

•our common stock constitutes a U.S. real property interest by reason of our status as a “United States real property holding corporation,” or USRPHC, for U.S. federal income tax purposes at any time within the shorter of the five-year period preceding the disposition and your holding period for our common stock.
If you are described in the first bullet above, you will generally be required to pay tax on the net gain derived from the sale at the same U.S. federal income tax rates applicable to U.S. persons (net of certain deductions and credits), and if you are a corporate non-U.S. holder, you may be subject to branch profits tax at a rate of 30% or such lower rate as may be specified
S-27

by an applicable income tax treaty. If you are described in the second bullet above, you will be required to pay a flat 30% tax on the gain derived from the sale, which tax may be offset by U.S. source capital losses (even though you are not considered a resident of the United States).
We believe that we are not currently and will not become a USRPHC. However, because the determination of whether we are a USRPHC depends on the fair market value of our U.S. real property relative to the fair market value of our other business assets, there can be no assurance that we will not become a USRPHC in the future. Even if we become a USRPHC, however, as long as our common stock is regularly traded on an established securities market, our common stock will be treated as a U.S. real property interest only if you actually or constructively hold more than 5% of such regularly traded common stock at any time during the applicable period described above.
Backup Withholding and Information Reporting
Generally, we must report annually to the IRS the amount of dividends paid to you, your name and address, and the amount of tax withheld, if any. A similar report will be sent to you. Pursuant to applicable income tax treaties or other agreements, the IRS may make these reports available to tax authorities in your country of residence.
The information reporting and backup withholding rules that apply to payments of dividends to certain U.S. stockholders of our common stock generally will not apply to dividends paid to a non-U.S. holder so long as the non-U.S. holder certifies its foreign status or otherwise establishes an exemption by properly certifying non-U.S. status on a Form W-8BEN or another appropriate version of IRS Form W-8. Notwithstanding the foregoing, backup withholding and information reporting may apply if either we or our paying agent has actual knowledge, or reason to know, that you are a U.S. person or that the conditions of any other exemption are not, in fact, satisfied.
Under the Treasury regulations, the payment of proceeds from the disposition of shares of our common stock by a non-U.S. holder made to or through a U.S. office of a broker generally will be subject to information reporting and backup withholding unless the beneficial owner certifies, under penalties of perjury, among other things, its status as a non-U.S. holder (and the broker does not have actual knowledge or reason to know the holder is a U.S. person) or otherwise establishes an exemption. The payment of proceeds from the disposition of shares of our common stock by a non-U.S. holder made to or through a non-U.S. office of a broker generally will not be subject to backup withholding and information reporting, except as noted below. Information reporting, but not backup withholding, will apply to a payment of proceeds, even if that payment is made outside of the United States, if you sell our common stock through a non-U.S. office of a broker that is:
•a U.S. person (including a foreign branch or office of such person);

•a “controlled foreign corporation” for U.S. federal income tax purposes;

•a foreign person 50% or more of whose gross income from certain periods is effectively connected with a U.S. trade or business; or

•a foreign partnership if at any time during its tax year (a) one or more of its partners are U.S. persons who, in the aggregate, hold more than 50% of the income or capital interests of the partnership or (b) the foreign partnership is engaged in a U.S. trade or business;
unless the broker has documentary evidence that the beneficial owner is a non-U.S. holder and certain other conditions are satisfied, or the beneficial owner otherwise establishes an exemption (and the broker has no actual knowledge or reason to know to the contrary). Backup withholding is not an additional tax. Any amounts withheld from a payment to you under the backup withholding rules will be allowed as a credit against your U.S. federal income tax liability and may entitle you to a refund, provided that the required information or returns are furnished to the IRS in a timely manner.
Foreign Accounts
The Foreign Account Tax Compliance Act, or FATCA, imposes a U.S. federal withholding tax of 30% on certain “withholdable payments,” including on dividends on, and the gross proceeds of a disposition of, our common stock to a “foreign financial institution” (as specifically defined for this purpose) unless such institution provides the withholding agent with a certification as to its FATCA status and either enters into an agreement with the U.S. government to withhold on
S-28

certain payments and to collect and provide to the U.S. tax authorities substantial information regarding U.S. account holders of such institution (which includes certain equity and debt holders of such institution, as well as certain account holders that are foreign entities with U.S. owners) or such institution otherwise qualifies for an exemption. A U.S. federal withholding tax of 30% is generally imposed on dividends on, and the gross proceeds of a disposition of, our common stock to a non-financial foreign entity unless such entity provides the withholding agent with a certification as to its FATCA status and either a certification that it does not have any substantial direct or indirect U.S. owners or information regarding direct and indirect U.S. owners of the entity or such entity otherwise qualifies for an exemption. Under applicable Treasury Regulations and IRS guidance, the withholding provisions described above currently apply to payments of dividends paid on our common stock, if any. FATCA generally would have applied to payments of gross proceeds from a sale or other disposition of our common stock, but under proposed Treasury Regulations (the preamble to which specifies that taxpayers are permitted to rely on such proposed Treasury Regulations pending finalization), no withholding would apply with respect to payments of gross proceeds. You should consult your tax advisors regarding the application of these withholding provisions to you.
Federal Estate Tax
Our common stock beneficially owned by an individual who is not a citizen or resident of the United States (as defined for U.S. federal estate tax purposes) at the time of death generally will be includable in the decedent’s gross estate for U.S. federal estate tax purposes, unless an applicable estate tax treaty provides otherwise.

The underwriting agreement will provide that the obligations of the several underwriters are subject to various conditions, including approval of legal matters by counsel. The nature of the underwriters’ obligations will commit them to purchase and pay for all of the shares of common stock listed above if any are purchased. The underwriters will reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.
Option to Purchase Additional Shares of Common Stock
We will grant the underwriters a 30-day option to purchase up to                   shares of our common stock at the public offering price, less the underwriting discount and commissions, as set forth on the cover page of this prospectus supplement. If the underwriters exercise their option in whole or in part, each of the underwriters will be separately committed, subject to the conditions described in the underwriting agreement, to purchase the additional shares of our common stock in proportion to their respective commitments set forth in the table above.
Commissions and Discounts
The underwriters propose to offer the shares directly to the public at the public offering price set forth on the cover page of this prospectus supplement, and at this price less a concession not in excess of $        per share of common stock to other dealers. After this offering, the offering price, concessions and other selling terms may be changed by the underwriters. Our shares of common stock will be offered subject to receipt and acceptance by the underwriters and to the other conditions, including the right to reject orders in whole or in part.

We will also agree to reimburse the underwriters up to $25,000 for certain of their expenses relating to the review of the offering by the Financial Industry Regulatory Authority, Inc.
Indemnification of Underwriters
We will indemnify the underwriters against certain civil liabilities, including liabilities under the Securities Act and liabilities arising from breaches of our representations and warranties contained in the underwriting agreement. If we are
S-30

unable to provide this indemnification, we will contribute to payments the underwriters may be required to make in respect of those liabilities. We will also agree to indemnify the underwriters for losses if the shares (other than those purchased pursuant to the underwriters’ option to purchase additional shares) are not delivered to the underwriters’ accounts on the initial settlement date.
No Sales of Similar Securities
We, our directors and our executive officers have entered, or will enter, into lock-up agreements with the representatives prior to the commencement of this offering pursuant to which we and each of these persons, for a period of 60 days after the date of this prospectus supplement, may not, subject to certain exceptions, offer, sell, contract to sell (including any short sale), pledge, hypothecate, establish an open “put equivalent position” within the meaning of Rule 16a‑1(h) under the Exchange Act, grant any option, right or warrant for the sale of, purchase any option or contract to sell, sell any option or contract to purchase or otherwise encumber, dispose of or transfer, grant any rights with respect to, directly or indirectly, any shares of common stock or securities convertible into or exchangeable for shares of common stock, enter into a transaction which would have the same effect or other arrangement that transfers, in whole or in part, any of the economic consequences of ownership of the common stock, whether such aforementioned transaction is to be settled by delivery of the common stock or such other securities, in cash or otherwise, or publicly disclose the intention to make any such offer, sale, pledge or disposition, or to enter into any such transaction, swap hedge or other arrangement, subject to specified exceptions. These restrictions shall also apply to any common stock received upon exercise of options granted to or warrants owned by each of the persons or entities described in the immediately preceding sentence. Among other exceptions, these restrictions will not apply to us with respect to issuances of common stock or securities exercisable for, convertible into or exchangeable for common stock in connection with any acquisition, collaboration, merger, licensing or other joint venture or strategic transaction involving our company, subject to certain limitations.

Listing
Our common stock is listed on the Nasdaq Global Select Market under the symbol “LASR.”
Short Sales, Stabilizing Transactions and Penalty Bids
In order to facilitate this offering, persons participating in this offering may engage in transactions that stabilize, maintain or otherwise affect the price of the shares during and after this offering. Specifically, the underwriters may engage in the following activities in accordance with the rules of the SEC.
Short Sales
Short sales involve the sales by the underwriters of a greater number of shares of common stock than they are required to purchase in the offering. Covered short sales are short sales made in an amount not greater than the underwriters’ option to purchase additional shares of common stock. The underwriters may close out any covered short position by either exercising their option to purchase additional shares or purchasing shares in the open market. In determining the source of shares to close out the covered short position, the underwriters will consider, among other things, the price of our common stock available for purchase in the open market as compared to the price at which they may purchase the shares through their option.
Naked short sales are any short sales in excess of such option to purchase additional shares of common stock. The underwriters must close out any naked short position by purchasing shares of our common stock in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of our common stock in the open market after pricing that could adversely affect investors who purchase in this offering.
Stabilizing Transactions
The underwriters may make bids for or purchases of shares of our common stock for the purpose of pegging, fixing or maintaining the price of our common stock, so long as stabilizing bids do not exceed a specified maximum.
S-31

Penalty Bids
If the underwriters purchase shares of our common stock in the open market in a stabilizing transaction or syndicate covering transaction, they may reclaim a selling concession from the underwriters and selling group members who sold those shares as part of this offering. Stabilization and syndicate covering transactions may cause the price of our common stock to be higher than it would be in the absence of these transactions. The imposition of a penalty bid might also have an effect on the price of the shares if it discourages resales of the shares.
The transactions above may occur on the Nasdaq Global Select Market or otherwise. Neither we nor the underwriters make any representation or prediction as to the effect that the transactions described above may have on the price of our common stock. If such transactions are commenced, they may be discontinued without notice at any time.
Discretionary Sales
The underwriters have informed us that they do not expect to confirm sales of the shares of common stock offered by this prospectus supplement to accounts over which they exercise discretionary authority without obtaining the specific approval of the account holder.
Electronic Distribution
A prospectus supplement in electronic format may be made available on the Internet or through other online services maintained by one or more of the underwriters participating in this offering, or by their affiliates. Other than the prospectus supplement in electronic format, the information on any underwriter’s website and any information contained in any other website maintained by an underwriter is not part of the prospectus supplement or the registration statement of which this prospectus supplement forms a part, has not been approved or endorsed by us or any underwriter in its capacity as underwriter and should not be relied upon by investors.

Relationships
The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, principal investment, hedging, financing and brokerage activities. Certain of the underwriters and their affiliates have in the past provided, and may in the future from time to time provide, investment banking and other financing and banking services to us, for which they have in the past received, and may in the future receive, customary fees and reimbursement for their expenses. In the ordinary course of their various business activities, the underwriters and their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments, including bank loans, for their own account and for the accounts of their customers and may at any time hold long and short positions in such securities and instruments.

Any resale of shares acquired by a Canadian investor in this offering must be made in accordance with applicable Canadian securities laws, which may vary depending on the relevant jurisdiction, and which may require resales to be made in accordance with Canadian prospectus requirements, a statutory exemption from the prospectus requirements, in a transaction exempt from the prospectus requirements or otherwise under a discretionary exemption from the prospectus requirements granted by the applicable local Canadian securities regulatory authority.

No representation or warranty is hereby made as to the tax consequences to a resident, or deemed resident, of Canada of an investment in the shares or with respect to the eligibility of the shares for investment by such investor under relevant Canadian federal and provincial legislation and regulations.
Rights of Action for Damages or Rescission
Securities legislation in certain of the Canadian jurisdictions provides certain purchasers of securities pursuant to an offering memorandum, including where the distribution involves an “eligible foreign security” as such term is defined in Ontario Securities Commission Rule 45-501 Ontario Prospectus and Registration Exemptions and in Multilateral Instrument 45-107 Listing Representation and Statutory Rights of Action Disclosure Exemptions, as applicable, with a remedy for damages or rescission, or both, in addition to any other rights they may have at law, where the offering memorandum, or other offering document that constitutes an offering memorandum, and any amendment thereto, contains a “misrepresentation” as defined under applicable Canadian securities laws. These remedies, or notice with respect to these remedies, must be exercised or delivered, as the case may be, by the purchaser within the time limits prescribed under, and are subject to limitations and defenses under, applicable Canadian securities legislation. In addition, these remedies are in addition to and without derogation from any other right or remedy available at law to the investor.

Our principal executive office is located at 5408 Northeast 88th Street, Building E, Vancouver, Washington 98665. Our telephone number is (360) 566-4460. Our website address is www.nlight.net.

The Securities That May Be Offered

We may offer or sell common stock, preferred stock, depositary shares, debt securities, warrants, subscription rights, purchase contracts and units in one or more offerings and in any combination up to an aggregate amount of $150,000,000. Each time securities are offered with this prospectus, we will provide a prospectus supplement that will describe the specific amounts, prices and terms of the securities being offered and the net proceeds we expect to receive from that sale.

The securities may be sold to or through underwriters, dealers or agents or directly to purchasers or as otherwise set forth in the section of this prospectus captioned “Plan of Distribution.” Each prospectus supplement will set forth the names of any underwriters, dealers, agents or other entities involved in the sale of securities described in that prospectus supplement and any applicable fee, commission or discount arrangements with them.

Common Stock

We may offer shares of our common stock, either alone or underlying other registered securities convertible into our common stock. Holders of our common stock are entitled to receive dividends declared by our board of directors out of funds legally available for the payment of dividends, subject to rights, if any, of preferred stockholders. We have not paid dividends in the past and have no current plans to pay dividends. Each holder of common stock is entitled to one vote per share. The holders of common stock have no preemptive rights.

Preferred Stock

Our board of directors has the authority, subject to limitations prescribed by Delaware law, to issue preferred stock in one or more series, to establish from time to time the number of shares to be included in each series, and to fix the designation, powers, preferences and rights of the shares of each series and any of its qualifications, limitations or restrictions, in each case without further vote or action by our stockholders. Each series of preferred stock offered by us will be more fully described in the particular prospectus supplement that will accompany this prospectus, including redemption provisions, rights in the event of our liquidation, dissolution or winding up, voting rights and rights to convert into common stock.

Depositary Shares

We may issue fractional shares of preferred stock that will be represented by depositary shares and depositary receipts.

Each series of depositary shares or depositary receipts offered by us will be more fully described in the particular prospectus supplement that will accompany this prospectus, including redemption provisions, rights in the event of our liquidation, dissolution or winding up, voting rights and rights to convert into common stock.

Debt Securities

We may offer secured or unsecured obligations in the form of one or more series of senior or subordinated debt. The senior debt securities and the subordinated debt securities are together referred to in this prospectus as the “debt securities.” The subordinated debt securities generally will be entitled to payment only after payment of our senior debt. Senior debt generally includes all debt for money borrowed by us, except debt that is stated in the instrument governing the terms of that debt to be not senior to, or to have the same rank in right of payment as, or to be expressly junior to, the subordinated debt securities. We may issue debt securities that are convertible into shares of our common stock.

The debt securities will be issued under an indenture between us and a trustee to be identified in an accompanying prospectus supplement. We have summarized the general features of the debt securities to be governed by the indenture in this prospectus and the form of indenture has been filed as an exhibit to the registration statement of which this prospectus forms a part. We encourage you to read the indenture.

Warrants

We may offer warrants for the purchase of common stock, preferred stock, debt securities or depositary shares. We may offer warrants independently or together with other securities.

Subscription Rights

We may offer subscription rights to purchase our common stock, preferred stock, debt securities, depositary shares, warrants or units consisting of some or all of these securities. These subscription rights may be offered independently or together with any other security offered hereby and may or may not be transferable by the stockholder receiving the subscription rights in such offering.

Purchase Contracts

We may offer purchase contracts, including contracts obligating holders or us to purchase from the other a specific or variable number of securities at a future date or dates.

Units

We may offer units comprised of one or more of the other classes of securities described in this prospectus in any combination. Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit.

RISK FACTORS

An investment in our securities involves a high degree of risk. The prospectus supplement applicable to each offering of our securities will contain a discussion of the risks applicable to an investment in our securities. Prior to making a decision about investing in our securities, you should carefully consider the specific factors discussed under the section in the applicable prospectus supplement captioned “Risk Factors,” together with all of the other information contained or incorporated by reference in the prospectus supplement or appearing or incorporated by reference in this prospectus. You should also consider the risks, uncertainties and assumptions discussed under “Part I—Item 1A—Risk Factors” of our most recent Annual Report on Form 10-K and in “Part II—Item 1A—Risk Factors” in our most recent Quarterly Report on Form 10-Q filed subsequent to such Form 10-K that are incorporated herein by reference, as may be amended, supplemented or superseded from time to time by other reports we file with the SEC in the future. The risks and uncertainties we have described are not the only ones we face. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our operations.

FORWARD-LOOKING STATEMENTS

This prospectus, each prospectus supplement and the information incorporated by reference in this prospectus and each prospectus supplement contain certain statements that constitute “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, or the Securities Act, and Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act. The words “believe,” “may,” “will,” “estimate,” “continue,” “anticipate,” “intend,” “expect,” “could,” “would,” “project,” “plan,” “potentially,” “likely,” and similar expressions and variations thereof are intended to identify forward-looking statements, but are not the exclusive means of identifying such statements. Those statements appear in this prospectus, any accompanying prospectus supplement and the documents incorporated herein and therein by reference, particularly in the sections captioned “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and include statements regarding the intent, belief or current expectations of our management that are subject to known and unknown risks, uncertainties and assumptions. You are cautioned that any such forward-looking statements are not guarantees of future performance and involve risks and uncertainties, and that actual results may differ materially from those projected in the forward-looking statements as a result of various factors.

Because forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified, you should not rely upon forward-looking statements as predictions of future events. The events and circumstances reflected in the forward-looking statements may not be achieved or occur and actual results could differ materially from those projected in the forward-looking statements. Except as required by applicable law, including the securities laws of the United States and the rules and regulations of the SEC, we do not plan to publicly update or revise any forward-looking statements contained herein after we distribute this prospectus, whether as a result of any new information, future events or otherwise.

In addition, statements that “we believe” and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based upon information available to us as of the date of this prospectus, and although we believe such information forms a reasonable basis for such statements, such information may be limited or incomplete, and our statements should not be read to indicate that we have conducted a thorough inquiry into, or review of, all potentially available relevant information. These statements are inherently uncertain and investors are cautioned not to unduly rely upon these statements.

This prospectus and the documents incorporated by reference in this prospectus may contain market data that we obtain from industry sources. These sources do not guarantee the accuracy or completeness of the information. Although we believe that our industry sources are reliable, we do not independently verify the information. The market data may include projections that are based on a number of other projections. While we believe these assumptions to be reasonable and sound as of the date of this prospectus, actual results may differ from the projections.

USE OF PROCEEDS

We will retain broad discretion over the use of the net proceeds to us from the sale of our securities under this prospectus. Unless otherwise provided in the applicable prospectus supplement, we currently expect to use the net proceeds that we receive from this offering for working capital and other general corporate purposes. We may also use a portion of the net proceeds to acquire, license or invest in complementary products, technologies or businesses; however, we currently have no agreements or commitments to complete any such transaction. The expected use of net proceeds of this offering represents our current intentions based on our present plans and business conditions. We cannot specify with certainty all of the particular uses for the net proceeds to be received upon the closing of this offering. Pending these uses, we plan to invest the net proceeds of this offering in short- and intermediate-term, interest-bearing obligations, investment-grade instruments, certificates of deposit or direct or guaranteed obligations of the U.S. government.

DESCRIPTION OF CAPITAL STOCK
The description of our capital stock is incorporated by reference to Exhibit 4.3 to our Annual Report on Form 10‑K for the fiscal year ended December 31, 2019, filed with the SEC on March 9, 2020.

DESCRIPTION OF DEBT SECURITIES

The following description, together with the additional information we include in any applicable prospectus supplement, summarizes certain general terms and provisions of the debt securities that we may offer under this prospectus. When we offer to sell a particular series of debt securities, we will describe the specific terms of the series in a supplement to this prospectus. We will also indicate in the supplement to what extent the general terms and provisions described in this prospectus apply to a particular series of debt securities.

We may issue debt securities either separately, or together with, or upon the conversion or exercise of or in exchange for, other securities described in this prospectus. Debt securities may be our senior, senior subordinated or subordinated obligations and, unless otherwise specified in a supplement to this prospectus, the debt securities will be our direct, unsecured obligations and may be issued in one or more series.

The debt securities will be issued under an indenture between us and a trustee to be identified in an accompanying prospectus supplement. We have summarized select portions of the indenture below. The summary is not complete. The form of the indenture has been filed as an exhibit to the registration statement of which this prospectus forms a part and you should read the indenture for provisions that may be important to you. In the summary below, we have included references to the section numbers of the indenture so that you can easily locate these provisions. Capitalized terms used in the summary and not defined herein have the meanings specified in the indenture.

General

The terms of each series of debt securities will be established by or pursuant to a resolution of our board of directors and set forth or determined in the manner provided in a resolution of our board of directors, in an officer’s certificate or by a supplemental indenture. The particular terms of each series of debt securities will be described in a prospectus supplement relating to such series (including any pricing supplement or term sheet).

We can issue an unlimited amount of debt securities under the indenture that may be in one or more series with the same or various maturities, at par, at a premium, or at a discount. We will set forth in a prospectus supplement (including any pricing supplement or term sheet) relating to any series of debt securities being offered the aggregate principal amount and the following terms of the debt securities, if applicable:

•the title and ranking of the debt securities (including the terms of any subordination provisions);
•the price or prices (expressed as a percentage of the principal amount) at which we will sell the debt securities;
•any limit upon the aggregate principal amount of the debt securities;
•the date or dates on which the principal of the securities of the series is payable;
•the rate or rates (which may be fixed or variable) per annum or the method used to determine the rate or rates (including any commodity, commodity index, stock exchange index or financial index) at which the debt securities will bear interest, the date or dates from which interest will accrue, the date or dates on which interest will commence and be payable and any regular record date for the interest payable on any interest payment date;
•the place or places where principal of, and interest, if any, on the debt securities will be payable (and the method of such payment), where the securities of such series may be surrendered for registration of transfer or exchange, and where notices and demands to us in respect of the debt securities may be delivered;

•any obligation we have to redeem or purchase the debt securities pursuant to any sinking fund or analogous provisions or at the option of a holder of debt securities and the period or periods within which, the price or prices at which and the terms and conditions upon which securities of the series shall be redeemed or purchased, in whole or in part, pursuant to such obligation;
•the dates on which and the price or prices at which we will repurchase debt securities at the option of the holders of debt securities and other detailed terms and provisions of these repurchase obligations;
•the denominations in which the debt securities will be issued, if other than denominations of $1,000 and any integral multiple thereof;
•whether the debt securities will be issued in the form of certificated debt securities or global debt securities;
•the portion of principal amount of the debt securities payable upon declaration of acceleration of the maturity date, if other than the principal amount;

4

•the currency of denomination of the debt securities, which may be United States dollars or any foreign currency, and if such currency of denomination is a composite currency, the agency or organization, if any, responsible for overseeing such composite currency;
•the designation of the currency, currencies or currency units in which payment of principal of, premium and interest on the debt securities will be made;
•if payments of principal of, premium or interest on the debt securities will be made in one or more currencies or currency units other than that or those in which the debt securities are denominated, the manner in which the exchange rate with respect to these payments will be determined;
•the manner in which the amounts of payment of principal of, premium, if any, or interest on the debt securities will be determined, if these amounts may be determined by reference to an index based on a currency or currencies or by reference to a commodity, commodity index, stock exchange index or financial index;
•any provisions relating to any security provided for the debt securities;
•any addition to, deletion of or change in the Events of Default described in this prospectus or in the indenture with respect to the debt securities and any change in the acceleration provisions described in this prospectus or in the indenture with respect to the debt securities;
•any addition to, deletion of or change in the covenants described in this prospectus or in the indenture with respect to the debt securities;
•any depositaries, interest rate calculation agents, exchange rate calculation agents or other agents with respect to the debt securities;
•any other terms of the debt securities, which may supplement, modify or delete any provision of the indenture as it applies to that series, including any terms that may be required under applicable law or regulations or advisable in connection with the marketing of the securities; and
•whether any of our direct or indirect subsidiaries will guarantee the debt securities of that series, including the terms of subordination, if any, of such guarantees.

We may issue debt securities that provide for an amount less than their stated principal amount to be due and payable upon declaration of acceleration of their maturity pursuant to the terms of the indenture. We will provide you with information on the federal income tax considerations and other special considerations applicable to any of these debt securities in the applicable prospectus supplement.

If we denominate the purchase price of any of the debt securities in a foreign currency or currencies or a foreign currency unit or units, or if the principal of and any premium and interest on any series of debt securities is payable in a foreign currency or currencies or a foreign currency unit or units, we will provide you with information on the restrictions, elections, general tax considerations, specific terms and other information with respect to that issue of debt securities and such foreign currency or currencies or foreign currency unit or units in the applicable prospectus supplement.

Transfer and Exchange

Each debt security will be represented by either one or more global securities registered in the name of a clearing agency registered under the Exchange Act, which we refer to as the depositary, or a nominee of the depositary (we will refer to any debt security represented by a global debt security as a “book-entry debt security”), or a certificate issued in definitive registered form (we will refer to any debt security represented by a certificated security as a “certificated debt security”) as set forth in the applicable prospectus supplement. Except as set forth under the heading “Global Debt Securities and Book-Entry System” below, book-entry debt securities will not be issuable in certificated form.

Certificated Debt Securities

You may transfer or exchange certificated debt securities at any office we maintain for this purpose in accordance with the terms of the indenture. No service charge will be made for any transfer or exchange of certificated debt securities, but we may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection with a transfer or exchange.

You may effect the transfer of certificated debt securities and the right to receive the principal of, premium and interest on certificated debt securities only by surrendering the certificate representing those certificated debt securities and either reissuance by us or the trustee of the certificate to the new holder or the issuance by us or the trustee of a new certificate to the new holder.

Global Debt Securities and Book-Entry System

Each global debt security representing book-entry debt securities will be deposited with, or on behalf of, the depositary, and registered in the name of the depositary or a nominee of the depositary.

Covenants

We will set forth in the applicable prospectus supplement any restrictive covenants applicable to any issue of debt securities.

No Protection in the Event of a Change of Control

Unless we state otherwise in the applicable prospectus supplement, the debt securities will not contain any provisions which may afford holders of the debt securities protection in the event we have a change in control or in the event of a highly leveraged transaction (whether or not such transaction results in a change in control) which could adversely affect holders of debt securities.

Consolidation, Merger and Sale of Assets

We may not consolidate with or merge with or into, or convey, transfer or lease all or substantially all of our properties and assets to any person, which we refer to as a successor person, unless:

•we are the surviving corporation or the successor person (if other than us) is a corporation organized and validly existing under the laws of any U.S. domestic jurisdiction and expressly assumes our obligations on the debt securities and under the indenture; and
•immediately after giving effect to the transaction, no Default or Event of Default, shall have occurred and be continuing.

Notwithstanding the above, any of our subsidiaries may consolidate with, merge into or transfer all or part of its properties to us.

Events of Default

“Event of Default” means with respect to any series of debt securities, any of the following:

•default in the payment of any interest upon any debt security of that series when it becomes due and payable, and continuance of such default for a period of 30 days (unless the entire amount of the payment is deposited by us with the trustee or with a paying agent prior to the expiration of the 30-day period);
•default in the payment of principal of any security of that series at its maturity;
•default in the performance or breach of any other covenant or warranty by us in the indenture (other than a covenant or warranty that has been included in the indenture solely for the benefit of a series of debt securities other than that series), which default continues uncured for a period of 60 days after we receive written notice from the trustee, or we and the trustee receive written notice from the holders of not less than 25% in principal amount of the outstanding debt securities of that series as provided in the indenture;
•certain voluntary or involuntary events of bankruptcy, insolvency or reorganization of us; and
•any other Event of Default provided with respect to debt securities of that series that is described in the applicable prospectus supplement.

No Event of Default with respect to a particular series of debt securities (except as to certain events of bankruptcy, insolvency or reorganization) necessarily constitutes an Event of Default with respect to any other series of debt securities. The occurrence of certain Events of Default or an acceleration under the indenture may constitute an event of default under certain indebtedness of ours or our subsidiaries outstanding from time to time.

We will provide the trustee written notice of any Default or Event of Default within 30 days of becoming aware of the occurrence of such Default or Event of Default, which notice will describe in reasonable detail the status of such Default or Event of Default and what action we are taking or propose to take in respect thereof.

If an Event of Default with respect to debt securities of any series at the time outstanding occurs and is continuing, then the trustee or the holders of not less than 25% in principal amount of the outstanding debt securities of that series may, by a notice in writing to us (and to the trustee if given by the holders), declare to be due and payable immediately the principal of (or, if the debt securities of that series are discount securities, that portion of the principal amount as may be specified in the terms of that series) and accrued and unpaid interest, if any, on all debt securities of that series. In the case of an Event of Default resulting from certain events of bankruptcy, insolvency or reorganization, the principal (or such specified amount) of and accrued and unpaid interest, if any, on all outstanding debt securities will become and be immediately due and payable without any declaration or other act on the part of the trustee or any holder of outstanding debt securities. At any time after a declaration of

6

acceleration with respect to debt securities of any series has been made, but before a judgment or decree for payment of the money due has been obtained by the trustee, the holders of a majority in principal amount of the outstanding debt securities of that series may rescind and annul the acceleration if all Events of Default, other than the non-payment of accelerated principal and interest, if any, with respect to debt securities of that series, have been cured or waived as provided in the indenture. We refer you to the prospectus supplement relating to any series of debt securities that are discount securities for the particular provisions relating to acceleration of a portion of the principal amount of such discount securities upon the occurrence of an Event of Default.

The indenture provides that the trustee may refuse to perform any duty or exercise any of its rights or powers under the indenture unless the trustee receives indemnity satisfactory to it against any cost, liability or expense which might be incurred by it in performing such duty or exercising such right or power. Subject to certain rights of the trustee, the holders of a majority in principal amount of the outstanding debt securities of any series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee with respect to the debt securities of that series.

No holder of any debt security of any series will have any right to institute any proceeding, judicial or otherwise, with respect to the indenture or for the appointment of a receiver or trustee, or for any remedy under the indenture, unless:

•that holder has previously given to the trustee written notice of a continuing Event of Default with respect to debt securities of that series; and
•the holders of not less than 25% in principal amount of the outstanding debt securities of that series have made written request, and offered indemnity or security satisfactory to the trustee, to the trustee to institute the proceeding as trustee, and the trustee has not received from the holders of not less than a majority in principal amount of the outstanding debt securities of that series a direction inconsistent with that request and has failed to institute the proceeding within 60 days.

Notwithstanding any other provision in the indenture, the holder of any debt security will have an absolute and unconditional right to receive payment of the principal of, premium and any interest on that debt security on or after the due dates expressed in that debt security and to institute suit for the enforcement of payment.

The indenture requires us, within 120 days after the end of our fiscal year, to furnish to the trustee a statement as to compliance with the indenture. If a Default or Event of Default occurs and is continuing with respect to the securities of any series and if it is known to a responsible officer of the trustee, the trustee shall send to each securityholder of the securities of that series notice of a Default or Event of Default within 90 days after it occurs or, if later, after a responsible officer of the trustee has knowledge of such Default or Event of Default. The indenture provides that the trustee may withhold notice to the holders of debt securities of any series of any Default or Event of Default (except in payment on any debt securities of that series) with respect to debt securities of that series if the trustee determines in good faith that withholding notice is in the interest of the holders of those debt securities.

Modification and Waiver

We and the trustee may modify, amend or supplement the indenture or the debt securities of any series without the consent of any holder of any debt security:

•to cure any ambiguity, defect or inconsistency;
•to comply with covenants in the indenture described above under the heading “Consolidation, Merger and Sale of Assets”;
•to provide for uncertificated securities in addition to or in place of certificated securities;
•to add guarantees with respect to debt securities of any series or secure debt securities of any series;
•to surrender any of our rights or powers under the indenture;
•to add covenants or events of default for the benefit of the holders of debt securities of any series;
•to comply with the applicable procedures of the applicable depositary;
•to make any change that does not adversely affect the rights of any holder of debt securities;
•to provide for the issuance of and establish the form and terms and conditions of debt securities of any series as permitted by the indenture;
•to effect the appointment of a successor trustee with respect to the debt securities of any series and to add to or change any of the provisions of the indenture to provide for or facilitate administration by more than one trustee; or
•to comply with requirements of the SEC in order to effect or maintain the qualification of the indenture under the Trust Indenture Act.


7

We may also modify and amend the indenture with the consent of the holders of at least a majority in principal amount of the outstanding debt securities of each series affected by the modifications or amendments. We may not make any modification or amendment without the consent of the holders of each affected debt security then outstanding if that amendment will:

•reduce the amount of debt securities whose holders must consent to an amendment, supplement or waiver;
•reduce the rate of or extend the time for payment of interest (including default interest) on any debt security;
•reduce the principal of or premium on or change the fixed maturity of any debt security or reduce the amount of, or postpone the date fixed for, the payment of any sinking fund or analogous obligation with respect to any series of debt securities;
•reduce the principal amount of discount securities payable upon acceleration of maturity;
•waive a default in the payment of the principal of, premium or interest on any debt security (except a rescission of acceleration of the debt securities of any series by the holders of at least a majority in aggregate principal amount of the then outstanding debt securities of that series and a waiver of the payment default that resulted from such acceleration);
•make the principal of or premium or interest on any debt security payable in currency other than that stated in the debt security;
•make any change to certain provisions of the indenture relating to, among other things, the right of holders of debt securities to receive payment of the principal of, premium and interest on those debt securities and to institute suit for the enforcement of any such payment and to waivers or amendments; or
•waive a redemption payment with respect to any debt security.

Except for certain specified provisions, the holders of at least a majority in principal amount of the outstanding debt securities of any series may on behalf of the holders of all debt securities of that series waive our compliance with provisions of the indenture. The holders of a majority in principal amount of the outstanding debt securities of any series may on behalf of the holders of all the debt securities of such series waive any past default under the indenture with respect to that series and its consequences, except a default in the payment of the principal of, premium or any interest on any debt security of that series; provided, however, that the holders of a majority in principal amount of the outstanding debt securities of any series may rescind an acceleration and its consequences, including any related payment default that resulted from the acceleration.

Defeasance of Debt Securities and Certain Covenants in Certain Circumstances

Legal Defeasance

The indenture provides that, unless otherwise provided by the terms of the applicable series of debt securities, we may be discharged from any and all obligations in respect of the debt securities of any series (subject to certain exceptions). We will be so discharged upon the irrevocable deposit with the trustee, in trust, of money and/or U.S. government obligations or, in the case of debt securities denominated in a single currency other than U.S. dollars, government obligations of the government that issued or caused to be issued such currency, that, through the payment of interest and principal in accordance with their terms, will provide money or U.S. government obligations in an amount sufficient in the opinion of a nationally recognized firm of independent public accountants or investment bank to pay and discharge each installment of principal, premium and interest on and any mandatory sinking fund payments in respect of the debt securities of that series on the stated maturity of those payments in accordance with the terms of the indenture and those debt securities.

This discharge may occur only if, among other things, we have delivered to the trustee an opinion of counsel stating that we have received from, or there has been published by, the United States Internal Revenue Service a ruling or, since the date of execution of the indenture, there has been a change in the applicable United States federal income tax law, in either case to the effect that, and based thereon such opinion shall confirm that, the holders of the debt securities of that series will not recognize income, gain or loss for United States federal income tax purposes as a result of the deposit, defeasance and discharge and will be subject to United States federal income tax on the same amounts and in the same manner and at the same times as would have been the case if the deposit, defeasance and discharge had not occurred.

Defeasance of Certain Covenants

The indenture provides that, unless otherwise provided by the terms of the applicable series of debt securities, upon compliance with certain conditions:

•we may omit to comply with the covenant described under the heading “Consolidation, Merger and Sale of Assets” and certain other covenants set forth in the indenture, as well as any additional covenants which may be set forth in the applicable prospectus supplement; and
•any omission to comply with those covenants will not constitute a Default or an Event of Default with respect to the debt securities of that series.

8


We refer to this as covenant defeasance. The conditions include:

•depositing with the trustee money and/or U.S. government obligations or, in the case of debt securities denominated in a single currency other than U.S. dollars, government obligations of the government that issued or caused to be issued such currency, that, through the payment of interest and principal in accordance with their terms, will provide money in an amount sufficient in the opinion of a nationally recognized firm of independent public accountants or investment bank to pay and discharge each installment of principal of, premium and interest on and any mandatory sinking fund payments in respect of the debt securities of that series on the stated maturity of those payments in accordance with the terms of the indenture and those debt securities;
•such deposit will not result in a breach or violation of, or constitute a default under the indenture or any other agreement to which we are a party;
•no Default or Event of Default with respect to the applicable series of debt securities shall have occurred or is continuing on the date of such deposit; and
•delivering to the trustee an opinion of counsel to the effect that we have received from, or there has been published by, the United States Internal Revenue Service a ruling or, since the date of execution of the indenture, there has been a change in the applicable United States federal income tax law, in either case to the effect that, and based thereon such opinion shall confirm that, the holders of the debt securities of that series will not recognize income, gain or loss for United States federal income tax purposes as a result of the deposit and related covenant defeasance and will be subject to United States federal income tax on the same amounts and in the same manner and at the same times as would have been the case if the deposit and related covenant defeasance had not occurred.

No Personal Liability of Directors, Officers, Employees or Stockholders

None of our past, present or future directors, officers, employees or stockholders, as such, will have any liability for any of our obligations under the debt securities or the indenture or for any claim based on, or in respect or by reason of, such obligations or their creation. By accepting a debt security, each holder waives and releases all such liability. This waiver and release is part of the consideration for the issue of the debt securities. However, this waiver and release may not be effective to waive liabilities under U.S. federal securities laws, and it is the view of the SEC that such a waiver is against public policy.

Governing Law

The indenture and the debt securities, including any claim or controversy arising out of or relating to the indenture or the securities, will be governed by the laws of the State of New York.

The indenture will provide that we, the trustee and the holders of the debt securities (by their acceptance of the debt securities) irrevocably waive, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to the indenture, the debt securities or the transactions contemplated thereby.

The indenture will provide that any legal suit, action or proceeding arising out of or based upon the indenture or the transactions contemplated thereby may be instituted in the federal courts of the United States of America located in the City of New York or the courts of the State of New York in each case located in the City of New York, and we, the trustee and the holder of the debt securities (by their acceptance of the debt securities) irrevocably submit to the non-exclusive jurisdiction of such courts in any such suit, action or proceeding. The indenture will further provide that service of any process, summons, notice or document by mail (to the extent allowed under any applicable statute or rule of court) to such party’s address set forth in the indenture will be effective service of process for any suit, action or other proceeding brought in any such court. The indenture will further provide that we, the trustee and the holders of the debt securities (by their acceptance of the debt securities) irrevocably and unconditionally waive any objection to the laying of venue of any suit, action or other proceeding in the courts specified above and irrevocably and unconditionally waive and agree not to plead or claim any such suit, action or other proceeding has been brought in an inconvenient forum.

DESCRIPTION OF DEPOSITARY SHARES
General

We may, at our option, elect to offer fractional shares of preferred stock, or depositary shares, rather than full shares of preferred stock. If we do, we will issue to the public receipts, called depositary receipts, for depositary shares, each of which will represent a fraction, to be described in the applicable prospectus supplement, of a share of a particular series of preferred stock. Unless otherwise provided in the prospectus supplement, each owner of a depositary share will be entitled, in proportion to the applicable fractional interest in a share of preferred stock represented by the depositary share, to all the rights and preferences of the preferred stock represented by the depositary share. Those rights include dividend, voting, redemption, conversion and liquidation rights.

9

The shares of preferred stock underlying the depositary shares will be deposited with a bank or trust company selected by us to act as depositary under a deposit agreement between us, the depositary and the holders of the depositary receipts. The depositary will be the transfer agent, registrar and dividend disbursing agent for the depositary shares.

The depositary shares will be evidenced by depositary receipts issued pursuant to the depositary agreement. Holders of depositary receipts agree to be bound by the deposit agreement, which requires holders to take certain actions such as filing proof of residence and paying certain charges.

The summary of terms of the depositary shares contained in this prospectus is not complete. You should refer to the form of the deposit agreement, our certificate of incorporation and the certificate of designation for the applicable series of preferred stock that are, or will be, filed with the SEC.

Dividends and Other Distributions

The depositary will distribute all cash dividends or other cash distributions, if any, received in respect of the preferred stock underlying the depositary shares to the record holders of depositary shares in proportion to the numbers of depositary shares owned by those holders on the relevant record date. The relevant record date for depositary shares will be the same date as the record date for the underlying preferred stock.

If there is a distribution other than in cash, the depositary will distribute property (including securities) received by it to the record holders of depositary shares, unless the depositary determines that it is not feasible to make the distribution. If this occurs, the depositary may, with our approval, adopt another method for the distribution, including selling the property and distributing the net proceeds from the sale to the holders.

Liquidation Preference

If a series of preferred stock underlying the depositary shares has a liquidation preference, in the event of the voluntary or involuntary liquidation, dissolution or winding up of us, holders of depositary shares will be entitled to receive the fraction of the liquidation preference accorded each share of the applicable series of preferred stock, as set forth in the applicable prospectus supplement.

Withdrawal of Stock

Unless the related depositary shares have been previously called for redemption, upon surrender of the depositary receipts at the office of the depositary, the holder of the depositary shares will be entitled to delivery, at the office of the depositary to or upon his or her order, of the number of whole shares of the preferred stock and any money or other property represented by the depositary shares. If the depositary receipts delivered by the holder evidence a number of depositary shares in excess of the number of depositary shares representing the number of whole shares of preferred stock to be withdrawn, the depositary will deliver to the holder at the same time a new depositary receipt evidencing the excess number of depositary shares. In no event will the depositary deliver fractional shares of preferred stock upon surrender of depositary receipts. Holders of preferred stock thus withdrawn may not thereafter deposit those shares under the deposit agreement or receive depositary receipts evidencing depositary shares therefor.

Redemption of Depositary Shares

Whenever we redeem shares of preferred stock held by the depositary, the depositary will redeem as of the same redemption date the number of depositary shares representing shares of the preferred stock so redeemed, so long as we have paid in full to the depositary the redemption price of the preferred stock to be redeemed plus an amount equal to any accumulated and unpaid dividends on the preferred stock to the date fixed for redemption. The redemption price per depositary share will be equal to the redemption price and any other amounts per share payable on the preferred stock multiplied by the fraction of a share of preferred stock represented by one depositary share. If less than all the depositary shares are to be redeemed, the depositary shares to be redeemed will be selected by lot or pro rata or by any other equitable method as may be determined by the depositary.

After the date fixed for redemption, depositary shares called for redemption will no longer be deemed to be outstanding and all rights of the holders of depositary shares will cease, except the right to receive the monies payable upon redemption and any money or other property to which the holders of the depositary shares were entitled upon redemption upon surrender to the depositary of the depositary receipts evidencing the depositary shares.




10

Voting the Preferred Stock

Upon receipt of notice of any meeting at which the holders of the preferred stock are entitled to vote, the depositary will mail the information contained in the notice of meeting to the record holders of the depositary receipts relating to that preferred stock. The record date for the depositary receipts relating to the preferred stock will be the same date as the record date for the preferred stock. Each record holder of the depositary shares on the record date will be entitled to instruct the depositary as to the exercise of the voting rights pertaining to the number of shares of preferred stock represented by that holder’s depositary shares. The depositary will endeavor, insofar as practicable, to vote the number of shares of preferred stock represented by the depositary shares in accordance with those instructions, and we will agree to take all action that may be deemed necessary by the depositary in order to enable the depositary to do so. The depositary will not vote any shares of preferred stock except to the extent that it receives specific instructions from the holders of depositary shares representing that number of shares of preferred stock.

Charges of the Depositary

We will pay all transfer and other taxes and governmental charges arising solely from the existence of the depositary arrangements. We will pay charges of the depositary in connection with the initial deposit of the preferred stock and any redemption of the preferred stock. Holders of depositary receipts will pay transfer, income and other taxes and governmental charges and such other charges (including those in connection with the receipt and distribution of dividends, the sale or exercise of rights, the withdrawal of the preferred stock and the transferring, splitting or grouping of depositary receipts) as are expressly provided in the deposit agreement to be for their accounts. If these charges have not been paid by the holders of depositary receipts, the depositary may refuse to transfer depositary shares, withhold dividends and distributions and sell the depositary shares evidenced by the depositary receipt.

Amendment and Termination of the Deposit Agreement

The form of depositary receipt evidencing the depositary shares and any provision of the deposit agreement may be amended by agreement between us and the depositary. However, any amendment that materially and adversely alters the rights of the holders of depositary shares, other than fee changes, will not be effective unless the amendment has been approved by the holders of a majority of the outstanding depositary shares. The deposit agreement may be terminated by the depositary or us only if:

•all outstanding depositary shares have been redeemed; or
•there has been a final distribution of the preferred stock in connection with our dissolution and such distribution has been made to all the holders of depositary shares.

Resignation and Removal of Depositary

The depositary may resign at any time by delivering to us notice of its election to do so, and we may remove the depositary at any time. Any resignation or removal of the depositary will take effect upon our appointment of a successor depositary and its acceptance of such appointment. The successor depositary must be appointed within 60 days after delivery of the notice of resignation or removal and must be a bank or trust company having its principal office in the United States and having the requisite combined capital and surplus as set forth in the applicable agreement.

Notices

The depositary will forward to holders of depositary receipts all notices, reports and other communications, including proxy solicitation materials received from us, that are delivered to the depositary and that we are required to furnish to the holders of the preferred stock. In addition, the depositary will make available for inspection by holders of depositary receipts at the principal office of the depositary, and at such other places as it may from time to time deem advisable, any reports and communications we deliver to the depositary as the holder of preferred stock.

Limitation of Liability

Neither we nor the depositary will be liable if either is prevented or delayed by law or any circumstance beyond its control in performing its obligations. Our obligations and those of the depositary will be limited to performance in good faith of our and its duties thereunder. We and the depositary will not be obligated to prosecute or defend any legal proceeding in respect of any depositary shares or preferred stock unless satisfactory indemnity is furnished. We and the depositary may rely upon written advice of counsel or accountants, on information provided by persons presenting preferred stock for deposit, holders of depositary receipts or other persons believed to be competent to give such information and on documents believed to be genuine and to have been signed or presented by the proper party or parties.

We may offer warrants separately or together with one or more additional warrants, debt securities, preferred stock, depositary shares or common stock, or any combination of those securities in the form of units, as described in the applicable prospectus supplement.

DESCRIPTION OF SUBSCRIPTION RIGHTS

We may issue subscription rights to purchase our common stock, preferred stock, debt securities, depositary shares, warrants or units consisting of some or all of these securities. These subscription rights may be offered independently or together with any other security offered hereby and may or may not be transferable by the stockholder receiving the subscription rights in such offering. In connection with any offering of subscription rights, we may enter into a standby arrangement with one or more underwriters or other purchasers pursuant to which the underwriters or other purchasers may be required to purchase any securities remaining unsubscribed for after such offering.

The prospectus supplement relating to any subscription rights we offer, if any, will, to the extent applicable, include specific terms relating to the offering, including some or all of the following:

•the price, if any, for the subscription rights;
•the exercise price payable for our common stock, preferred stock, debt securities, depositary shares, warrants or units consisting of some or all of these securities upon the exercise of the subscription rights;
•the number of subscription rights to be issued to each stockholder;
•the number and terms of our common stock, preferred stock, debt securities, depositary shares, warrants or units consisting of some or all of these securities which may be purchased per each subscription right;
•the extent to which the subscription rights are transferable;

12

•any other terms of the subscription rights, including the terms, procedures and limitations relating to the exchange and exercise of the subscription rights;

•if applicable, the material terms of any standby underwriting or purchase arrangement which may be entered into by us in connection with the offering of subscription rights.

The descriptions of the subscription rights in this prospectus and in any prospectus supplement are summaries of the material provisions of the applicable subscription right agreements. These descriptions do not restate those subscription right agreements in their entirety and may not contain all the information that you may find useful. We urge you to read the applicable subscription right agreements because they, and not the summaries, define your rights as holders of the subscription rights. For more information, please review the forms of the relevant subscription right agreements, which will be filed with the SEC promptly after the offering of subscription rights and will be available as described in the section of this prospectus captioned “Where You Can Find More Information.”

DESCRIPTION OF PURCHASE CONTRACTS

The following description summarizes the general features of the purchase contracts that we may offer under this prospectus. Although the features we have summarized below will generally apply to any future purchase contracts we may offer under this prospectus, we will describe the particular terms of any purchase contracts that we may offer in more detail in the applicable prospectus supplement. The specific terms of any purchase contracts may differ from the description provided below as a result of negotiations with third parties in connection with the issuance of those purchase contracts, as well as for other reasons. Because the terms of any purchase contracts we offer under a prospectus supplement may differ from the terms we describe below, you should rely solely on information in the applicable prospectus supplement if that summary is different from the summary in this prospectus.

We will incorporate by reference into the registration statement of which this prospectus is a part the form of any purchase contract that we may offer under this prospectus before the sale of the related purchase contract. We urge you to read any applicable prospectus supplement related to specific purchase contracts being offered, as well as the complete instruments that contain the terms of the securities that are subject to those purchase contracts. Certain of those instruments, or forms of those instruments, have been filed as exhibits to the registration statement of which this prospectus is a part, and supplements to those instruments or forms may be incorporated by reference into the registration statement of which this prospectus is a part from reports we file with the SEC.

We may issue purchase contracts, including contracts obligating holders to purchase from us, and for us to sell to holders, a specific or variable number of our securities at a future date or dates. Alternatively, the purchase contracts may obligate us to purchase from holders, and obligate holders to sell to us, a specific or varying number of our securities.

If we offer any purchase contracts, certain terms of that series of purchase contracts will be described in the applicable prospectus supplement, including, without limitation, the following:

•the price of the securities or other property subject to the purchase contracts (which may be determined by reference to a specific formula described in the purchase contracts);
•whether the purchase contracts are issued separately, or as a part of units each consisting of a purchase contract and one or more of our other securities, including U.S. Treasury securities, securing the holder’s obligations under the purchase contract;
•any requirement for us to make periodic payments to holders or vice versa, and whether the payments are unsecured or pre-funded;
•any provisions relating to any security provided for the purchase contracts;
•whether the purchase contracts obligate the holder or us to purchase or sell, or both purchase and sell, the securities subject to purchase under the purchase contract, and the nature and amount of each of those securities, or the method of determining those amounts;
•whether the purchase contracts are to be prepaid or not;
•whether the purchase contracts are to be settled by delivery, or by reference or linkage to the value, performance or level of the securities subject to purchase under the purchase contract;
•any acceleration, cancellation, termination or other provisions relating to the settlement of the purchase contracts;
•a discussion of certain U.S. federal income tax considerations applicable to the purchase contracts;
•whether the purchase contracts will be issued in fully registered or global form; and
•any other terms of the purchase contracts and any securities subject to such purchase contracts.

13

DESCRIPTION OF UNITS

We may issue units comprising two or more securities described in this prospectus in any combination. For example, we might issue units consisting of a combination of debt securities and warrants to purchase common stock. The following description sets forth certain general terms and provisions of the units that we may offer pursuant to this prospectus. The particular terms of the units and the extent, if any, to which the general terms and provisions may apply to the units so offered will be described in the applicable prospectus supplement.

Each unit will be issued so that the holder of the unit also is the holder of each security included in the unit. Thus, the unit will have the rights and obligations of a holder of each included security. Units will be issued pursuant to the terms of a unit agreement, which may provide that the securities included in the unit may not be held or transferred separately at any time or at any time before a specified date. A copy of the forms of the unit agreement and the unit certificate relating to any particular issue of units will be filed with the SEC each time we issue units, and you should read those documents for provisions that may be important to you. For more information on how you can obtain copies of the forms of the unit agreement and the related unit certificate, see the section of this prospectus captioned “Where You Can Find More Information.”

The prospectus supplement relating to any particular issuance of units will describe the terms of those units, including, to the extent applicable, the following:

•the designation and terms of the units and the securities comprising the units, including whether and under what circumstances those securities may be held or transferred separately;
•any provision for the issuance, payment, settlement, transfer or exchange of the units or of the securities comprising the units; and
•whether the units will be issued in fully registered or global form.

PLAN OF DISTRIBUTION

We may sell securities:

•through underwriters;
•through dealers;
•through agents;
•directly to purchasers; or
•through a combination of any of these methods of sale.

In addition, we may issue the securities as a dividend or distribution or in a subscription rights offering to our existing securityholders.

We may directly solicit offers to purchase securities or agents may be designated to solicit such offers. We will, in the prospectus supplement relating to such offering, name any agent that could be viewed as an underwriter under the Securities Act and describe any commissions that we must pay. Any such agent will be acting on a best efforts basis for the period of its appointment or, if indicated in the applicable prospectus supplement, on a firm commitment basis. This prospectus may be used in connection with any offering of our securities through any of these methods or other methods described in the applicable prospectus supplement.

The distribution of the securities may be effected from time to time in one or more transactions:

•at a fixed price or prices that may be changed from time to time;
•at market prices prevailing at the time of sale;
•at prices related to such prevailing market prices; or
•at negotiated prices.

Each prospectus supplement will describe the method of distribution of the securities and any applicable restrictions.

The prospectus supplement with respect to the securities of a particular series will describe the terms of the offering of the securities, including the following:

•the name of the agent or any underwriters;
•the public offering or purchase price;
•if applicable, the names of any selling securityholders;
•any discounts and commissions to be allowed or paid to the agent or underwriters;

14

•all other items constituting underwriting compensation;
•any discounts and commissions to be allowed or paid to dealers; and
•any exchanges on which the securities will be listed.

If any underwriters or agents are utilized in the sale of the securities in respect of which this prospectus is delivered, we will enter into an underwriting agreement or other agreement with them at the time of sale to them, and we will set forth in the prospectus supplement relating to such offering the names of the underwriters or agents and the terms of the related agreement with them.

If a dealer is utilized in the sale of the securities in respect of which the prospectus is delivered, we will sell such securities to the dealer, as principal. The dealer may then resell such securities to the public at varying prices to be determined by such dealer at the time of resale.

If we offer securities in a subscription rights offering to our existing securityholders, we may enter into a standby underwriting agreement with dealers, acting as standby underwriters. We may pay the standby underwriters a commitment fee for the securities they commit to purchase on a standby basis. If we do not enter into a standby underwriting arrangement, we may retain a dealer-manager to manage a subscription rights offering for us.

Agents, underwriters, dealers and other persons may be entitled under agreements that they may enter into with us to indemnification by us against certain civil liabilities, including liabilities under the Securities Act.

If so indicated in the applicable prospectus supplement, we will authorize underwriters or other persons acting as our agents to solicit offers by certain institutions to purchase securities from us pursuant to delayed delivery contracts providing for payment and delivery on the date stated in the prospectus supplement. Each contract will be for an amount not less than, and the aggregate amount of securities sold pursuant to such contracts shall not be less nor more than, the respective amounts stated in the prospectus supplement. Institutions with whom the contracts, when authorized, may be made include commercial and savings banks, insurance companies, pension funds, investment companies, educational and charitable institutions and other institutions, but shall in all cases be subject to our approval. Delayed delivery contracts will not be subject to any conditions except that:

•the purchase by an institution of the securities covered under that contract shall not at the time of delivery be prohibited under the laws of the jurisdiction to which that institution is subject; and
•if the securities are also being sold to underwriters acting as principals for their own account, the underwriters shall have purchased such securities not sold for delayed delivery.

The underwriters and other persons acting as agents will not have any responsibility in respect of the validity or performance of delayed delivery contracts.

Certain agents, underwriters and dealers, and their associates and affiliates may be customers of, have borrowing relationships with, engage in other transactions with, and/or perform services, including investment banking services, for us or one or more of our respective affiliates in the ordinary course of business.

In order to facilitate the offering of the securities, any underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the securities or any other securities the prices of which may be used to determine payments on such securities. Specifically, any underwriters may over-allot in connection with the offering, creating a short position for their own accounts. In addition, to cover over-allotments or to stabilize the price of the securities or of any such other securities, the underwriters may bid for, and purchase, the securities or any such other securities in the open market. Finally, in any offering of the securities through a syndicate of underwriters, the underwriting syndicate may reclaim selling concessions allowed to an underwriter or a dealer for distributing the securities in the offering if the syndicate repurchases previously distributed securities in transactions to cover syndicate short positions, in stabilization transactions or otherwise. Any of these activities may stabilize or maintain the market price of the securities above independent market levels. Any such underwriters are not required to engage in these activities and may end any of these activities at any time.

Under Rule 15c6-1 of the Exchange Act, trades in the secondary market generally are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. The applicable prospectus supplement may provide that the original issue date for your securities may be more than two scheduled business days after the trade date for your securities. Accordingly, in such a case, if you wish to trade securities on any date prior to the third business day before the original issue date for your securities, you will be required, by virtue of the fact that your securities initially are expected to settle in more than three scheduled business days after the trade date for your securities, to make alternative settlement arrangements to prevent a failed settlement.

15

The securities may be new issues of securities and may have no established trading market. The securities may or may not be listed on a national securities exchange. We can make no assurance as to the liquidity of or the existence of trading markets for any of the securities.

LEGAL MATTERS

The validity of the securities offered hereby will be passed upon for us by Wilson Sonsini Goodrich & Rosati, Professional Corporation, Seattle, Washington. As of the date of this prospectus, the members and associates of Wilson Sonsini Goodrich & Rosati, Professional Corporation, as a group, own less than 1% of our outstanding shares of common stock.
