RISK FACTORS

         Investing in our common stock involves a high degree of risk. Before making an investment decision, you should carefully consider the risks and uncertainties described below, which we believe are the material risks associated with our business and this offering. Our business, financial condition, results of operations and growth prospects could be materially adversely affected by any of these risks. In that event, the trading price of our common stock could decline as a result of any of these risks materializing, and you may lose part of or all of your investment. In assessing these risks, you should also refer to all of the other information contained in this prospectus, including our consolidated financial statements and related notes. Some statements in this prospectus, including statements in the following risk factors, constitute forward-looking statements. See "Special Note Regarding Forward-Looking Statements and Industry Data."

Risks Related to Our Business and Industry

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 net losses each year since our inception in 2000 through 2016, and only first became profitable in 2017. Although we had net income of $1.8 million on 2017, we had a net loss of $14.2 million in 2016. We had an accumulated deficit of $118.7 million as of December 31, 2017.

        We 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 continue 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 and the market price of our common stock may decline.

Our revenue growth rate in recent periods may not be indicative of our future performance.

        In recent periods, we have experienced substantial levels of revenue growth. However, 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 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. If we are unable to maintain consistent revenues or revenue growth, our stock price could decline.

Downturns 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. The revenue growth of our business substantially depends on demand for our products in the industrial and microfabrication markets. For our products sold to the industrial market, we believe demand is largely based on general economic conditions, primarily in China and North America. Adverse changes in the global economy have occurred and may occur in the future as a result of declining or flat global or regional economic conditions, fluctuations in currency and commodity prices, wavering confidence, unemployment, declines in stock markets, contraction of credit availability or other factors affecting economic conditions generally. 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 in part on the demand for our products from semiconductor equipment companies. The semiconductor equipment market has

13

Table of Contents

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. The timing, severity and duration of these market cycles are difficult to predict, which limits our ability to predict our business prospects and financial results in this market and we may not be able to respond effectively to these cycles.

        During industry downturns in the past, our revenues from this market declined suddenly and significantly, and this is likely to occur again in the event of industry downturns in the future. Our ability to rapidly and effectively reduce our cost structure in response to such downturns is limited by the fixed nature of many of our expenses in the near term and by our need to continue our investment in next-generation product technology and to support and service our products. In addition, due to the relatively long manufacturing lead times for some of the systems and subsystems we sell to this market, we may incur expenditures or purchase raw materials or components for products we cannot sell. Conversely, when upturns in this market occur, we must be able to rapidly and effectively increase our manufacturing capacity to meet increases in customer demand that may be extremely rapid, and if we fail to do so we may lose business to our competitors and our relationships with our customers may be harmed.

We have high levels of fixed costs and inventory levels that may materially adversely affect our gross profits and results of operations in the event that 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, we may need to record write-downs for excess or obsolete inventory. For example, we typically increase our inventory levels in the period leading up to Chinese New Year, which occurs during our first fiscal quarter, in anticipation of increased sales to our Chinese customers after completion of the holiday. If these anticipated sales do not occur, we may need to record write-downs for excess inventory.

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 not only with companies providing semiconductor and fiber lasers, but 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. Certain of these competitors also have higher sales volume than we do, which can enable such competitors to lower the prices of their products. To compete, we may be forced to lower our prices, which could negatively impact our revenues and gross margins. Consolidation in our industry could intensify the competitive pressures that we face. Our competitors worldwide include BWT Beijing Ltd., Coherent, Inc., II-VI Incorporated, IPG Photonics Corporation, Lumentum Holdings Inc., Maxphotonics Co., Ltd., Raycus Fiber Laser Technologies Co. Ltd. and Trumpf GmbH + Co. KG.

        We also compete with widely used non-laser production methods, such as plasma cutting, water-jet cutting and resistance welding. We believe that competition will be particularly intense from makers of CO2, YAG and disc lasers, as makers of these laser solutions may lower their prices in order to maintain market share and have committed significant research and development resources to pursue opportunities related to these technologies. If manufacturers of these non-laser and legacy laser solutions offer

14

Table of Contents

significantly lower prices than we do for our products, customers may choose to purchase their products instead of ours, despite any technical or performance advantage our products may offer.

        Our OEM customers' internal production of laser technologies presents additional competitive pressure. To the extent our OEM customers move towards using such in-house technologies, we may need to lower our prices to remain competitive, otherwise our market share and revenues may be materially adversely affected.

        To be 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.

Our inability to manage risks associated with our international customers and operations could materially adversely affect our business.

        Approximately 66% of our revenues were to customers outside of North America in 2017. We anticipate that foreign revenues, particularly revenues from Asia, will continue to account for a significant portion of our revenues in the foreseeable future. Our products are sold in over 30 countries. Our principal markets outside of North America include China, South Korea, Japan and other Asian countries, Germany and other European countries. We have offices outside of the United States in Lohja, Finland, Shanghai, China and Seoul, South Korea. We have substantial tangible assets outside of the United States, particularly in China.

        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, reliance in some jurisdictions on third-party revenues from channel partners, preference for locally produced products and shipping, other logistics complications and longer accounts receivable collection periods.

        Our business could also be impacted by international conflicts, terrorist and military activity, civil unrest and pandemic illness which could cause a slowdown in customer orders, cause customer order cancellations or negatively impact availability of supplies or limit our ability to 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 operations in Finland, China and South Korea and our other existing and potential future international business operations could materially adversely affect our business, financial condition, results of operations and growth prospects.

We have substantial sales and operations in China, which exposes us to risks inherent in doing business there.

        Our business operations in China and our sales to Chinese customers are critical to our success. As of February 28, 2018, we had approximately 470 employees at our Shanghai facility where we have high-volume packaging and sales operations. Moreover, in 2017, approximately 40% of our revenues were derived from China. As a result, downturns in the Chinese economy could materially adversely affect our

15

Table of Contents

results of operations. The Chinese economy differs from the economies of other developed countries in many respects, including the level of government involvement, level of development, growth rate and control of foreign exchange and allocation of resources. The Chinese economy has been transitioning from a planned economy to a more market-oriented economy. Despite reforms, the government continues to exercise significant control over China's economic growth by way of the allocation of resources, control over foreign currency-denominated obligations and monetary policy and provision of preferential treatment to particular industries or companies. We cannot predict the future economic policies of the Chinese government or their effect on the regional or global economy and we cannot predict other governments' economic policies toward China. Any downturn in the Chinese economy as a result of these or other events may lead to a significant reduction in demand for our products.

        The political, legal and regulatory climate in China, both nationally and regionally, is fluid and unpredictable, and operating in China exposes us to political and legal risks. Our ability to operate in China may be materially adversely affected by changes in Chinese laws and regulations such as those related to, among other things, taxation, import and export tariffs, environmental regulations, land use rights, intellectual property, currency controls, network security, employee benefits and overtime policies and other matters. Our operations in China are subject to numerous laws, regulations, rules and specifications relating to human health and safety and the environment. Applicable laws, rules and regulations often lack clarity and it is difficult to predict how any of these laws, rules and regulations will be enforced. If we or our employees or agents violate, or are alleged to have violated, any of these laws, rules and regulations, we or our employees could be subject to civil or criminal penalties, damages or fines, or our employees or agents could be detained, imprisoned or prevented from entering China, any of which could materially adversely affect our results of operations.

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.

        We rely on a few customers for a significant portion of our revenues. In the aggregate, our top ten customers accounted for approximately 61% and 60% of our revenues in 2017 and 2016, respectively. Suzhou Quick Laser Technology Co., Ltd accounted for 14% and 11% of our revenues in 2017 and 2016, respectively, and Raytheon Company accounted for 10% of our revenues in 2016. We generally do not enter into long-term purchase agreements with our customers obligating them to purchase our products.

16

Table of Contents

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 protect our proprietary technology and intellectual property rights, our competitive position could be harmed and our results of operations could be materially adversely affected.

        Our success depends in part upon our ability to obtain, maintain and enforce patents, trade secrets, trademarks and other intellectual property rights and to operate without infringing on or otherwise violating the proprietary rights of others or having third parties infringe, misappropriate or circumvent the rights we own or license. We rely on a variety of intellectual property rights, including patents, copyrights, trademarks, trade secrets, technical know-how and other unpatented proprietary information to protect our products, product development and manufacturing activities from unauthorized copying 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. Some of our know-how or technology is not patented or patentable and may constitute trade secrets. To protect our trade secrets, we have a policy of requiring our employees, consultants, advisors and other collaborators who contribute to our material intellectual property to enter into confidentiality agreements. We also rely on customary contractual protections with our suppliers and customers, and we implement security measures intended to protect our trade secrets, know-how or other proprietary information. However, 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. 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. Although we typically enter into confidentiality agreements with our employees who contribute to our material intellectual property to protect our proprietary information, our ability to enforce such agreements in foreign jurisdictions is uncertain. In the past, certain of our employees have been hired by our competitors. These former employees are contractually prohibited from misappropriating our confidential information, including trade secrets; however, we cannot be certain that such contractual obligations will be honored. While we monitor our competitors' activities for evidence of infringement of our proprietary rights, we cannot be certain that such infringement will be detected. If we 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. The steps that we take to acquire ownership of our employees' inventions and trade secrets in foreign countries may not have been effective under all such local laws, which could expose us to potential claims or the inability to protect intellectual property developed by our employees. 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.

17

Table of Contents

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-based 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 harm our ability to do business; that there could be existing patents of which we are unaware that could be pertinent to our business; and that it is not possible for us to know whether there are patent applications pending that our products might infringe upon, since patent applications often are not disclosed until a patent is issued or published. 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.

        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 as a result 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 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.

        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, whether or not they have merit, could be time-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.

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.

        Any 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.

18

Table of Contents

        Our current and potential customers may have substantial investment in, and know-how related to, their existing laser and non-laser technologies. They may perceive risks relating to the reliability, quality, usefulness and profitability of integrating semiconductor lasers or fiber lasers in their systems when compared to other laser or non-laser technologies available in the market or that they manufacture themselves. Although we believe that semiconductor lasers and fiber lasers generally exhibit superior performance compared to other lasers or tools, 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 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.

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. In addition, we experience seasonality in our results of operations with our first quarter typically impacted by lower demand from our Chinese customers during Chinese New Year. 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;

•

delays in our product-shipment timing, 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 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;

•

our ability to obtain export licenses for our products on a timely basis or at all;

•

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;

•

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;

•

different capital expenditure and budget cycles for our customers, which affect the timing of their spending;

•

foreign currency fluctuations; and

•

economic and market conditions in a particular geography or country.

19

Table of Contents

        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. Our results of operations in future quarters and years may be below public market analysts' or investors' expectations, which would likely cause the price of our stock to fall, perhaps significantly. In addition, over the past several years, U.S. and global equity markets have experienced significant price and volume fluctuations that have affected the stock prices of many technology companies both in and outside our industry. There has not always been a direct correlation between this volatility and the performance of particular companies subject to these stock price fluctuations. These factors, as well as general economic and political conditions or investors' concerns regarding the credibility of corporate financial statements, may materially adversely affect the market price of our stock in the future.

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, are experiencing and may in the future continue to experience a significant decline in average selling prices, or ASPs, on maturing products as a result of increased competition and price pressures from customers. As competing products become more widely available, the ASPs of our products may decrease. Due to the fixed cost of production, the average cost per unit 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. 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 are able to 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 will depend in part on the successful development, introduction and market acceptance of new and enhanced products that address these changes as well as current and potential customer requirements. We expect that new technologies will emerge as competition and our customers' need for higher and more cost-effective tools increase. The introduction of new and enhanced products may cause our customers to defer or cancel orders for existing

20

Table of Contents

products. 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 achieve and 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.

        The development of new, technologically advanced products is a complex and uncertain process that requires the accurate prediction of technological and market trends, as well as the investment of significant research and development expenses. Further, we typically invest substantial resources in advance of material sales of our products to our customers. Our research and development costs were $15.1 million in 2017. 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, if at all, or on a timely basis. Further, we cannot assure you that our new products will gain market acceptance or that we will be able to respond effectively to product announcements by competitors, technological changes or emerging industry standards. Many of these factors are beyond our control. Any failure to respond to technological change would materially adversely affect our business, financial condition, results of operations and growth prospects.

        Additionally, our product offerings may become obsolete given the frequent introduction of alternative technologies. In the event either our customers or our products fail to gain and maintain market acceptance, it would likely materially adversely affect our business, financial condition, results of operations and growth prospects.

Reliance on customers in the aerospace and defense industry for a significant portion of our revenues could materially adversely affect our business, financial condition, results of operations and growth prospects.

        In 2017, we derived approximately 15% of our revenues from customers in the aerospace and defense industry. From time to time, we have experienced declining aerospace and defense-related revenues. The aerospace and defense market is largely dependent upon 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, such as appropriations bills and accords on the debt ceiling. As a result, our future revenues are subject in part to the uncertainties of governmental budgeting and appropriations and national defense policies and priorities, including sequestration impacts similar to those experienced under the Budget Control Act of 2011, or the BCA, constraints of the budgetary process and timing and potential changes to these policies and priorities. Future spending levels are subject to a wide range of outcomes, depending on Congressional action, all of which are beyond our control. Moreover, no assurance can be given that an increase in defense spending will be allocated to programs that would benefit our business.

21

Table of Contents

        Many of our customers in the defense industry are subcontractors that must negotiate our proposals with the U.S. government. Our continuing relationship and the ability of these customers to pay for our products is 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.

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. The U.S. government contracting party may require us to increase 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, in which case we may be required to decrease 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, including the Defense Contract Audit Agency, the Defense Contract Management Agency and various agency Inspectors General, routinely audit and investigate government contractors. These agencies review a contractor's performance under its contracts, its cost structure, its business systems and compliance with applicable laws, regulations and standards. The U.S. government has the ability to 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 exposed to foreign currency risk, which may materially adversely affect our revenues, cost of revenues and operating margins and could result in exchange losses.

        We conduct our business and incur costs in the local currency of most countries in which we operate. In 2017, our revenues outside North America represented approximately 66% of our revenues. We incur currency transaction risk whenever one or more of our operating subsidiaries enter into a transaction using currencies different than their functional currency. Changes in exchange rates can also affect our results of operations when the value of revenues and expenses of foreign subsidiaries are translated to U.S. dollars. We do not actively hedge our foreign currency exposure and we cannot accurately predict the impact of future exchange rate fluctuations on our results of operations. Further, given the volatility of exchange rates, we may not be able to effectively manage our currency risks, and any volatility in currency exchange rates may increase the price of our products in local currency to our foreign customers or increase the manufacturing cost of our products, which could decrease demand for our products in such markets. Any of the foregoing could materially adversely affect our business, financial condition, results of operations and growth prospects.

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 not 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.

        We generally do not enter into long-term agreements with our customers obligating them to purchase our products. 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. Write-downs have been recorded as a result of changes in demand or uncertainties related to the recoverability of the value of inventories due to technological and product changes. 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 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.

The estimates of market opportunity and forecasts of market growth included in this prospectus may prove to be inaccurate, and even if the market in which we compete achieves the forecasted growth, our business could fail to grow at similar rates, if at all.

        Market opportunity estimates and growth forecasts included in this prospectus are subject to significant uncertainty and are based on assumptions and estimates that may not prove to be accurate. Similarly, the continued pace of reduction in cost per brilliant watt and increase in power output of semiconductor lasers is based on assumptions and prior experience, and may not continue at the same rate, which could materially adversely affect the growth of high-power fiber lasers generally, and our growth

Table of Contents

specifically. Even if the markets in which we compete meet the size estimates and growth forecasted in this prospectus, and even if semiconductor lasers continue to become less expensive and more powerful, our business could fail to grow for a variety of reasons, which would adversely affect our results of operations. For more information regarding the estimates of market opportunity and the forecasts of market growth included in this prospectus, see the section titled "Special Note Regarding Forward-Looking Statements and Industry Data."

We depend upon internal production and on outside single or limited-source suppliers for many of our key components and raw materials, including cutting-edge optics and materials. 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. By their very nature, 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 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.

Failure to effectively maintain and expand our field service and support organization could materially adversely affect our business, financial condition, results of operations and growth prospects.

        It is important for us to provide rapid, responsive service directly to our customers throughout the world and to maintain and expand our own personnel resources to provide these services. Any actual or perceived lack of adequate field service in the locations where we sell or try to sell our products may negatively impact our sales efforts and, consequently, our revenues. This requires us to recruit and train additional qualified field service and support personnel as well as maintain effective and highly trained organizations that can provide service to our customers in various countries. We may not be able to attract and train additional qualified personnel to expand our direct support operations successfully, in a cost-effective manner or at all. We also may not be able to find and engage additional qualified third-party resources to supplement and enhance our direct support operations. Further, we may incur significantly higher costs in providing these field and support services if competition for or unavailability of these services is limited. Failure to implement and manage our support operation effectively could materially adversely affect our relationships with our customers, as well as our business, financial condition, results of operations and growth prospects.

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

25

Table of Contents

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.

We may experience lower than expected manufacturing yields, which would adversely affect our gross margins.

        The manufacture of semiconductor lasers and their packaging is a highly complex process. Manufacturers often encounter difficulties in achieving acceptable product yields from laser and packaging operations. We have from time to time experienced lower than anticipated manufacturing yields for our lasers. If we do not achieve planned yields, our product costs could increase, resulting in lower gross margins, and key component availability would decrease, which could result in delays in fulfilling customer orders or rolling out new product lines.

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 our proprietary and confidential information, including that of our customers, suppliers and employees. Accidental or willful security breaches or other unauthorized access to our facilities or information systems, or viruses, loggers, or other malfeasant code in our data or software, could compromise this information. The consequences of such loss and possible misuse of our proprietary and confidential information could include, among other things, unfavorable publicity, damage to our reputation, difficulty marketing our products, customer allegations of breach-of-contract, litigation by affected parties 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 "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 our service-providers' systems or viruses, loggers or other malfeasant code in their data or software could expose us to information loss and misappropriation of confidential information. 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 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.

Our business could be materially adversely affected if one or more members of our executive management team or key personnel departed.

        Any future success is substantially dependent on the continued contributions of our executive officers, including Scott Keeney, our president and chief executive officer. We are also dependent on key technologists, and other key engineering, sales, marketing, manufacturing and support personnel, any of whom may leave, which could harm our business and reputation in the market. Our business requires engineering staff with experience in several disciplines, including physics, optics, materials sciences, chemistry and electronics. We will need to continue to recruit and retain highly skilled engineers for certain functions.

        Any future success also depends in part on our ability to identify, attract, hire, train, retain and motivate highly skilled research and development, managerial, operations, sales, marketing and customer service personnel. We are continually recruiting such personnel. However, competition for such personnel

26

Table of Contents

can be strong and we can provide no assurance that we will be successful in attracting or retaining such personnel now or in the future. In addition, particularly in the high-technology industry, the value of stock options, restricted stock units, grants or other share-based compensation is an important element in the retention of employees. Declines in the value of our common stock after our initial public offering could materially adversely affect our ability to retain employees and we may have to take additional steps to make the equity component of our compensation packages more appealing to attract and retain employees. These steps could result in dilution to stockholders.

        If we fail to attract, integrate and retain the necessary personnel, our ability to extend and maintain our scientific expertise and grow our business could suffer significantly. The loss of any key employee, the failure of any key employee to adequately perform in his or her current position, our inability to attract, train and retain skilled employees as needed or the inability of our key employees to expand, train and manage our employee base as needed, could materially adversely affect our business, financial condition, results of operations and growth prospects.

Our management team has limited public company experience.

        We have never operated as a public company. Our chief financial officer joined us in January 2018 and is the only member of our management team who has prior experience as an executive officer of a public company. Our entire management team, as well as other company personnel, will need to devote substantial time to compliance, and may not effectively or efficiently manage our transition into a public company. If we are unable to effectively comply with the regulations applicable to public companies or if we are unable to produce accurate and timely financial statements, which may result in material misstatements in our financial statements or possible restatement of financial results, our stock price may be materially adversely affected, and we may be unable to maintain compliance with the listing requirements of The Nasdaq Stock Market. Any such failures could also result in litigation or regulatory actions by the SEC or other regulatory authorities, loss of investor confidence, delisting of our securities, harm to our reputation and diversion of financial and management resources from the operation of our business, any of which could materially adversely affect our business, financial condition, results of operations and growth prospects.

As a consequence of becoming a public company, we will be subject to additional regulatory compliance requirements, including Section 404 of the Sarbanes-Oxley Act of 2002. If we fail to maintain an effective system of internal controls then we may not be able to accurately report our consolidated financial results or prevent fraud.

        As a public company, we will be subject to the SEC's rules implementing Sections 302 and 404 of the Sarbanes-Oxley Act, which will require management to certify financial and other information in our quarterly and annual reports and provide, beginning with our second annual report on Form 10-K, an annual management report on the effectiveness of internal controls over financial reporting. In addition, we will be subject to the reporting requirements of the Exchange Act, the listing requirements of The Nasdaq Stock Market, and other applicable securities rules and regulations. As a consequence, and particularly after we cease to be an "emerging growth company," we will incur greater legal, accounting and other expenses than we incur as a private company, including costs associated with public company reporting requirements. We also anticipate that we will incur costs associated with relatively recently adopted corporate governance requirements, including requirements of the SEC and The Nasdaq Stock Market. We expect these rules and regulations to increase our legal and financial compliance costs and to make some activities more time-consuming and costly. We also expect that these rules and regulations may make it more difficult and more expensive for us to obtain director and officer liability insurance and we may be required to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. As a result, it may be more difficult for us to attract and retain qualified individuals to serve on our board of directors or as executive officers. We are currently evaluating and

27

Table of Contents

monitoring developments with respect to these rules, and we cannot predict or estimate the amount of additional costs we may incur or the timing of such costs.

        When our independent registered public accounting firm is required to undertake an assessment of our internal control over financial reporting, the cost of our compliance with Section 404 will correspondingly increase. Moreover, if we are not able to comply with the requirements of Section 404 applicable to us in a timely manner, or if we or our independent registered public accounting firm identify deficiencies in our internal control over financial reporting that are deemed to be material weaknesses, the market price of our stock could decline and we could be subject to sanctions or investigations by the SEC or other regulatory authorities, which would require additional financial and management resources.

Our operations are conducted in a limited number of locations. Any disruption at our facilities could delay revenues or increase our expenses.

        An earthquake, fire, flood or other natural or manmade disaster could disable our facilities, disrupt operations or cause catastrophic losses. Our major manufacturing facilities are located in Vancouver, Washington; Hillsboro, Oregon; Shanghai, China; and Lohja, Finland. Some of our facilities, such as our headquarters and key manufacturing and development facilities in Vancouver, Washington, are located in areas with a known history of seismic and volcanic activity. We also have facilities in areas with a known history of flooding, such as our location in Shanghai, China, and there is a risk of flooding and snowstorms at our location in Lohja, Finland. A loss at any of these or other of our or our suppliers' facilities could disrupt operations, delay production and shipments, reduce revenues and generate potentially significant expenses to repair or replace damaged facilities. The insurance we maintain against earthquakes, floods and other natural or manmade disasters may not be adequate to cover our losses in any particular case.

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, including the Commerce Department's Export Administration Regulations, the State Department's International Traffic in Arms Regulations, or ITAR, and various economic and trade sanctions established by the Treasury Department's Office of Foreign Assets Controls. We may not always be successful in obtaining necessary export licenses, and 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. While we are not aware of any current or proposed export or import regulations that will materially restrict our ability to sell our products, 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.

28

Table of Contents

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, such as the U.S. Foreign Corrupt Practices Act of 1977, as amended, or the FCPA, the U.S. domestic bribery statute contained in 18 U.S.C. § 201, the U.S. Travel Act, the USA PATRIOT Act, the U.K. Bribery Act 2010, the Proceeds of Crime Act 2002 and possibly other anti-corruption, anti-bribery and anti-money laundering laws in countries in which we conduct activities. 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. China also strictly prohibits bribery of government officials and commercial bribery. Our operations in China 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.

        While we have policies and procedures in this area, we cannot guarantee that improprieties committed by our employees or third parties will not occur. 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. In certain cases, enforcement authorities may even require us to appoint an independent compliance monitor, which can result in added costs and administrative burdens. Any investigations, actions or sanctions or other previously mentioned harm could materially adversely affect our business, financial condition, results of operations and growth prospects.

Changes in U.S. or foreign tax law may materially adversely affect our business, financial condition, results of operations and growth prospects.

        The Tax Cuts and Jobs Act, or 2017 Tax Act, was recently enacted into law, bringing about extensive changes to the U.S. corporate tax system. The 2017 Tax Act includes changes that reduce U.S. corporate tax rates, change how U.S. multinational corporations, like us, are taxed on international earnings, repeal domestic manufacturing deduction, accelerate tax revenue recognition, allow capitalization of research and development expenditures, place additional limitations on executive compensation and limitations on the deductibility of interest. Certain aspects of the new tax law are currently unclear or undeveloped and we are unable to predict what effects such legislation might have on our future liability for U.S. corporate tax. Due to the large and expanding scale of our international business activities, any changes in the U.S. or foreign taxation of such activities may increase our worldwide effective tax rate and the amount of taxes we pay and seriously harm our business.

        Additionally, under the applicable laws and regulations in China, arrangements and transactions among related parties may be subject to audit or challenge by the Chinese tax authorities. We would be subject to adverse tax consequences if the Chinese tax authorities were to determine that the transactions with or between our subsidiaries were not executed on an arm's-length basis, and as a result the Chinese tax authorities could require that our Chinese subsidiaries adjust their taxable income upward for Chinese tax purposes. Such an adjustment could materially adversely affect us by increasing our tax expenses.

        We regularly assess the likelihood of favorable or unfavorable outcomes resulting from these examinations to determine the adequacy of our provision for income taxes. Although we believe our tax estimates are reasonable, there can be no assurance that any final determination will not be materially different than the treatment reflected in our historical income tax provisions and accruals, which could materially adversely affect our business, financial condition, results of operations and growth prospects.

We could be subject to additional income tax liabilities.

        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. Although we believe our tax estimates are reasonable, 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 international operations subject us to potential adverse tax consequences.

        We generally conduct our international operations through wholly-owned subsidiaries and report our taxable income in various jurisdictions worldwide based upon our business operations in those jurisdictions. Our intercompany relationships are subject to complex transfer pricing regulations administered by taxing authorities in various jurisdictions. The relevant taxing authorities may disagree with our determinations as to the income and expenses attributable to specific jurisdictions. If such a disagreement were to occur, and our position was not sustained, we could be required to pay additional taxes, interest and penalties, which could result in one-time tax charges, higher effective tax rates, reduced cash flows and lower overall profitability of our operations. We believe that our financial statements reflect adequate reserves to cover such a contingency, but there can be no assurances in that regard.

Our reported financial results may be materially adversely affected by changes in accounting principles generally accepted in the United States.

        Generally accepted accounting principles in the United States, or GAAP, are subject to interpretation by the Financial Accounting Standards Board, or FASB, the SEC, and various bodies formed to promulgate and interpret appropriate accounting principles. A change in these principles or interpretations could have a significant effect on our reported financial results, and could affect the reporting of transactions completed before the announcement of a change.

        In particular, in May 2014, the FASB issued FASB ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) , which supersedes the revenue recognition requirements in ASC 605, Revenue Recognition . The core principle of ASU 2014-09 is that an entity should recognize revenues to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. As an "emerging growth company" the JOBS Act allows us to delay adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements are made applicable to private companies. We have elected to use this extended transition period under the JOBS Act with respect to ASU 2014-09. We expect ASU 2014-09 to apply to us for reporting periods beginning in 2019.

Table of Contents

        While we continue to assess the potential impacts of ASU 2014-09 and anticipate it could have an impact on our consolidated financial statements, we do not know or cannot reasonably estimate the quantitative impact on our financial statements at this time.

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. Liability under environmental laws can be joint and several and without regard to comparative fault. 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. At this time, we do not believe the costs to maintain compliance with current environmental laws to be material. If such costs were to become material in the future, whether due to unanticipated changes in environmental laws or their interpretations, unanticipated changes in our operations or other unanticipated changes, we may be required to dedicate additional staff or financial resources in order to maintain compliance. There can be no assurance that violations of environmental laws or regulations will not occur in the future as a result of the lack of, or failure to obtain, permits, human error, accident, equipment failure or other causes.

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. Where we can make a reasonable estimate of the liability relating to pending litigation and determine that it is probable, we record a related liability. As additional information becomes available, we assess the potential liability and revise estimates as appropriate. However, because of uncertainties relating to litigation, the amount of our 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.

The outcome of any government inquiries and investigations involving our business is unpredictable and an adverse decision in any such matter could materially adversely affect our business, financial condition, results of operations and growth prospects.

        We have been involved in certain disputes and have also received requests for information from government authorities. For example, we entered into a civil settlement agreement with the U.S. Department of Justice in March 2015 concerning a matter related to our eligibility for certain contracts awarded to us under the Small Business Innovation Research, or SBIR, Program. We have also received information requests from the Criminal Division of the U.S. Attorney's Office related to our SBIR eligibility and the Criminal Division has interviewed certain of our current and past employees. We have responded to the U.S. Attorney's requests with a production of documents. Although we have not received further inquiries from the Criminal Division since 2015, the Criminal Division has contacted certain of our

31

Table of Contents

former employees as recently as June 2017 and the inquiry may be ongoing, and we do not know when it will conclude or whether the Criminal Division will pursue claims against us or our employees. If the Criminal Division or a federal court determines that we or our employees are criminally liable, our business, financial condition, results of operations and growth prospects could be materially adversely affected.

Acquisitions could result in operating difficulties and may materially adversely affect our business, financial condition, results of operations and growth prospects.

        We have evaluated, and expect to continue evaluating, potential strategic transactions, and we may pursue one or more transactions, including acquisitions. We have limited experience executing acquisitions. Any transaction could be material to our business, financial condition, results of operations and growth prospects. Integrating an acquired company, business or technology may create unforeseen operating difficulties and expenditures. Acquisition-related risks include:

•

diverting management time and focus from operating our business to acquisition integration;

•

difficulties integrating acquired products into our strategy and product plans;

•

customers moving to new suppliers as a result of the acquisition;

•

inability to retain employees from the business we acquire;

•

challenges associated with integrating employees from the acquired company into our organization;

•

difficulties integrating accounting, management information, human resource and other administrative systems to permit effective management of the business we acquire and realize efficiencies;

•

potential requirements for remediating controls, procedures and policies appropriate for a public company in the acquired business that prior to the acquisition lacked these controls, procedures and policies;

•

potential liability for past or present environmental, hazardous substance, or contamination concerns associated with the acquired business or its predecessors;

•

possible write-offs or impairment charges resulting from the acquisition; and

•

unanticipated or unknown liabilities relating to the acquired business.

        Foreign acquisitions involve additional risks beyond those above, including related to integrating operations across different cultures and languages, currency risks and the economic, political and regulatory risks associated with other countries. Also, the anticipated benefit of any acquisition, domestic or foreign, may not materialize. Future acquisitions or dispositions could result in potentially dilutive issuances of our equity securities, debt incurrence, contingent liabilities or amortization expenses or goodwill write-offs, any of which could materially adversely affect our business, financial condition, results of operations and growth prospects. Future acquisitions may require us to obtain additional equity or debt financing, which may not be available on favorable terms or at all.

Our debt obligations contain restrictions that impact our business and expose us to risks that could materially adversely affect our liquidity and financial condition.

        In March 2018, we entered into an amended and restated loan facility, or loan facility, with Pacific Western Bank, as lender. This loan facility imposes certain covenants and restrictions on our business and our ability to obtain additional financing. As of December 31, 2017, we had $13.5 million outstanding principal amount under the term loan and $3.7 million outstanding principal amount under the revolving loan facility.

        Among other things, our loan facility requires the lender's consent to:

•

merge or consolidate;

•

sell or transfer assets outside the ordinary course of business;

•

make certain types of investments and capital expenditures;

32

Table of Contents

•

incur additional indebtedness or guarantee indebtedness of others;

•

pay dividends, redeem or repurchase our capital stock;

•

enter into transactions with affiliates outside the ordinary course of business; and

•

create liens on our assets.

        Our loan facility also contains affirmative covenants, including a minimum revenue covenant and a maximum capital expenditures covenant. The facility contains events of default, including, among others, non-payment defaults, inaccuracy of representations and warranties, covenant defaults, cross-defaults to other indebtedness, judgment defaults, bankruptcy and insolvency defaults and a change of control default.

        If we experience a decline in cash flow due to any of the factors described in this "Risk Factors" section or otherwise, we could have difficulty paying interest and principal amounts due on our indebtedness and meeting the financial covenants set forth in our loan facility. If we are unable to generate sufficient cash flow or otherwise obtain the funds necessary to make required payments under our loan facility, or if we fail to comply with the requirements of our indebtedness, we could default under our loan facility. Any default that is not cured or waived could result in the acceleration of the obligations under the loan facility, an increase in the applicable interest rate under the loan facility, and would permit our lender to exercise remedies with respect to all of the collateral that is securing the loan facility, which includes substantially all of our assets. Any such default could materially adversely affect our liquidity and financial condition.

        Even if we comply with all of the applicable covenants, the restrictions on the conduct of our business could materially adversely affect our business by, among other things, limiting our ability to take advantage of financings, mergers, acquisitions and other corporate opportunities that may be beneficial to the business. Even if the loan facility were terminated, additional debt we could incur in the future may subject us to similar or additional covenants, which could place restrictions on the operation of our business.

Our ability to use net operating losses to offset future taxable income may be limited.

        As of December 31, 2017, we had U.S. federal and state net operating loss carryforwards, or NOLs, of $104.5 million and $13.7 million, respectively and federal and state research development credit carryforwards of $4.2 million and $0.1 million, respectively, which we may use to reduce future taxable income or offset income taxes due. The NOLs and credit carryforwards start expiring in 2020 and 2018, respectively. Insufficient future taxable income will adversely affect our ability to deploy these NOLs and credit carryforwards. 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 in connection with or after this offering. 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 if we attain profitability.

Risks Related to Our Common Stock and this Offering

The market price of our common stock may be volatile, and the value of your investment could decline significantly.

        There has been no public market for our common stock prior to this offering. The initial price to public for our common stock will be determined through negotiations between us and the underwriters, and the negotiated price may not be indicative of the market price of the common stock after the offering. Investors who purchase common stock in this offering may not be able to sell their shares at or above the initial price to public. The lack of an active market may impair investors' ability to sell their shares at the

33

Table of Contents

time they wish to sell them or at a price that they consider reasonable, may reduce the market value of their shares and may impair our ability to raise capital. Securities of companies similar to ours experience significant price and volume fluctuations. The following factors, in addition to other risks described in this prospectus, may have a significant effect on our common stock price:

•

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;

•

the trading volume of our stock;

•

limited public float;

•

any future sales 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 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.

If securities or industry analysts do not publish research reports about our business, or if they issue an adverse opinion about our business, our stock price and trading volume could decline.

        The trading market for our common stock will be influenced by the research and reports that industry or securities analysts publish about us or our business. We do not currently have, and may never obtain, research coverage by securities and industry analysts. We do not have any control over these analysts. If no or few analysts commence research coverage of us, or one or more of the analysts who cover us issues an adverse opinion about our company, our stock price would likely decline. If one or more of these analysts ceases research coverage of us or fails to regularly publish reports on us, we could lose visibility in the financial markets, which in turn could cause our stock price or trading volume to decline.

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 after this offering or the perception that these sales could occur. These sales, or the possibility that these

34

Table of Contents

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.

        Upon the closing of this offering,            shares (            shares if the underwriters exercise in full their option to purchase additional shares) of our common stock will be outstanding, based on our shares outstanding as of December 31, 2017. All shares of common stock to be sold in this offering will be freely tradable without restriction or further registration under the Securities Act unless held by our "affiliates," as that term is defined in Rule 144 under the Securities Act. The resale of the remaining            shares of our common stock, or approximately        % of our outstanding shares after this offering, is currently prohibited or otherwise restricted as a result of securities law provisions, market standoff agreements entered into by our stockholders with us or lock-up agreements entered into by our stockholders with the underwriters; however, subject to applicable securities law restrictions, these shares will be able to be sold in the public market beginning 180 days after the date of this prospectus. In addition, the shares subject to outstanding options and warrants, of which options and warrants to purchase 26,844,807 shares and 1,072,225 shares, respectively, were outstanding as of December 31, 2017, and the shares reserved for future issuance under our stock option and equity incentive plans will become available for sale immediately upon the exercise of such options and the expiration of any applicable market stand-off or lock-up agreements, and Rule 144 and Rule 701 under the Securities Act. For more information see the section titled "Shares Eligible for Future Sale."

        Upon the closing of this offering, the holders of 127,779,798 shares (including the shares underlying warrants described in the section titled "Shares Eligible for Future Sale—Warrants"), or approximately      % of our common stock, will have rights, subject to some conditions, to require us to file registration statements covering the sale of their shares or to include their shares in registration statements that we may file for ourselves or other stockholders, based on our shares outstanding as of December 31, 2017. We also intend to register the offer and sale of all shares of common stock that we may issue under our equity compensation plans. Once we register the offer and sale of shares for the holders of registration rights and shares to be issued under our equity incentive plans, they can be freely sold in the public market upon issuance, subject to the lock-up agreements and the restrictions of Rule 144 under the Securities Act in the case of our affiliates, described in the section titled "Shares Eligible For Future Sale."

        In addition, in the future, we may issue additional shares of common stock or other equity or debt securities convertible into common stock in connection with a financing, acquisition, commercial relationship, litigation settlement, employee arrangements or otherwise. Any such issuance could result in substantial dilution to our existing stockholders and could cause our stock price to decline.

Our principal stockholders and management own a significant percentage of our stock and will be able to exercise significant influence over matters subject to stockholder approval.

        Our executive officers, directors and principal stockholders, together with their respective affiliates, beneficially owned approximately 81% of our common stock as of March 30, 2018, and we expect that upon completion of this offering, that same group will beneficially own at least        % of our capital stock. Accordingly, after this offering, our executive officers, directors and principal stockholders will be able to determine the composition of our board of directors, retain the voting power to approve all matters requiring stockholder approval, including mergers and other business combinations, and continue to have significant influence over our operations. This concentration of ownership could have the effect of delaying or preventing a change in our control or otherwise discouraging a potential acquirer from attempting to obtain control of us, which in turn could materially adversely affect our stock price and may prevent attempts by our stockholders to replace or remove our board of directors or management.

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, including the costs associated with being a public company. 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.

We are an "emerging growth company," and any decision on our part to comply only with certain reduced reporting and disclosure requirements applicable to emerging growth companies could make our common stock less attractive to investors.

        We are an "emerging growth company," as defined in the Jumpstart Our Business Startups, or JOBS, Act enacted in April 2012, and, for as long as we continue to be an "emerging growth company," we may choose to take advantage of exemptions from various reporting requirements applicable to other public companies but not to "emerging growth companies," including, but not limited to, not being required to have our independent registered public accounting firm audit our internal control over financial reporting under Section 404 of the Sarbanes-Oxley Act of 2002, or Section 404, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. We could be an "emerging growth company" for up to five years following the closing of this offering, although, if we have more than $1.07 billion in annual revenues, if the market value of our common stock that is held by non-affiliates exceeds $700 million as of June 30 of any year, or we issue more than $1.0 billion of non-convertible debt over a three-year period before the end of that five-year period, we would cease to be an "emerging growth company" as of the following December 31. We cannot predict if investors will find our common stock less attractive if we choose to rely on these exemptions. If some investors find our common stock less attractive as a result of any choices to reduce future disclosure, there may be a less active trading market for our common stock and our stock price may be more volatile.

        As an "emerging growth company," the JOBS Act allows us to delay adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements are made applicable to private companies. We have elected to use this extended transition period under the JOBS Act. As a result, our financial statements may not be comparable to the financial statements of issuers who are required to comply with the effective dates for new or revised accounting standards that are applicable to public companies, which may make our common stock less attractive to investors.

Delaware and Washington law and provisions in our amended and restated certificate of incorporation and amended and restated bylaws that will be in effect at the closing of this offering could make a merger, tender offer or proxy contest difficult, thereby depressing the trading price of our common stock.

        Anti-takeover provisions in our charter documents and under Delaware and Washington law could make an acquisition of us difficult, limit attempts by our stockholders to replace or remove our current management or board of directors and adversely affect our stock price.

        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

36

Table of Contents

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 will:

•

permit the board of directors to issue up to                        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 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, because we are incorporated in Delaware, 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." See the section titled "Description of Capital Stock—Anti-Takeover Effects of Delaware and Washington Law and Our Certificate of Incorporation and Bylaws" for additional information.

        Our amended and restated bylaws will 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.

37

Table of Contents

        Our amended and restated bylaws will also provide that the federal district courts of the United States of America will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act.

        Any person or entity purchasing or otherwise acquiring any interest in any of our securities shall be deemed to have notice of and consented to this provision. 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.
