Department’s Office of Foreign Assets Controls. These regulations may limit the export of our products and technology, and provision of our services outside of the United States, or may require export authorizations, including by license, a license exception, or other appropriate government authorizations and conditions, including annual or semi-annual reporting. Export control and economic sanctions laws may also include prohibitions on the sale or supply of certain of our products to embargoed or sanctioned countries, regions, governments, persons, and entities. For example, we sell to markets in Asia where multiple companies have been added to the Entity List, requiring license for exports of items subject to control under the EAR. To our knowledge, we have not sold products subject to the EAR to Entity List persons. In addition, various countries regulate the importation of certain products, through import permitting and licensing requirements, and have enacted laws that could limit our ability to distribute our products. The exportation, re-exportation, and importation of our products and technology and the provision of services, including by our partners, must comply with U.S. and other laws or else we may be adversely affected through reputational harm, government investigations, penalties, and a denial or curtailment of our ability to export our products and technology. Although we take precautions to prevent our products and technology from being provided in violation of such laws, our products and technology may have previously been, and could in the future be, provided inadvertently in violation of such laws, despite the precautions we take. These laws and regulations are continuously and rapidly evolving, and the scope and interpretation of the laws and regulations that are or may be applicable to us are often uncertain and may be conflicting. Changes in export or import laws or sanctions policies also may adversely impact our operations, delay the introduction and sale of our products in international markets, or, in some cases, prevent the export or import of our products and technology to certain countries, regions, governments, persons, or entities altogether, which could adversely affect our business, financial condition, and results of operations.
Our internal control over financial reporting may not prevent or detect misstatements because of its inherent limitations, including the possibility of human error, failure or interruption of information technology systems, the circumvention or overriding of controls, or fraud.
Even effective internal controls can provide only reasonable assurance with respect to the preparation and fair presentation of financial statements. If we fail to maintain the adequacy of our internal controls, including any failure to implement required new or improved controls, or if we experience difficulties in their implementation, our business and operating results could be harmed, and we could fail to meet our financial reporting obligations.
Changes in environmental laws or regulations, as well as sustainability initiatives, could impose substantial costs and may adversely affect our business.
Our product or manufacturing standards could be impacted by new or revised environmental rules and regulations or other social initiatives. For example, a significant portion of our revenue comes from international sales. Environmental laws or regulations in those countries or in the countries of our end customers may increase our cost of doing business and adversely affect our business and results of operations.
Many customers, regulators, investors, employees, and other stakeholders are focusing on sustainability matters. While we have certain sustainability initiatives, there is no assurance that customers, regulators, investors, and employees will determine that these programs are sufficient. Any actual or perceived shortcomings with respect to our sustainability initiatives and reporting can impact our ability to retain certain customers or increase our customer base, reelect our board of directors, attract and retain certain types of investors, or hire and retain employees. Collecting, measuring, and reporting sustainability information and metrics can be costly, difficult and time consuming, is subject to evolving reporting standards, and can present numerous operational, reputational, financial, legal, and other risks, any of which could adversely affect our business as well as on our reputation and stock price.
New or future changes to U.S. and non-U.S. tax laws could materially adversely affect us.
New or future changes in tax laws, regulations, and treaties, or the interpretation thereof, in addition to tax regulations enacted but not in effect, tax policy initiatives and reforms under consideration in the United States or related to the Organization for Economic Co-operation and Development’s, Base Erosion and Profit Shifting Project (“BEPSP”), the European Commission’s state aid investigations, and other initiatives could have an adverse effect on the taxation of international businesses. Furthermore, countries where we are subject to taxes, including the United States, are independently evaluating their tax policy and we may see significant changes in legislation and regulations concerning taxation. Certain countries have already enacted legislation, including those related to BEPSP, which could affect international businesses, and other countries have become more aggressive in their approach to audits and enforcement of their applicable tax laws. In addition, we are unable to predict what future tax reform may be proposed or enacted or what effect such changes would have on our business, but any changes, to the extent they are brought into tax legislation, regulations, policies, or practices, could increase our effective tax rates in the countries where we have operations and have an adverse effect on our overall tax rate, along with increasing the complexity, burden and cost of tax compliance, all of which could impact our business, financial condition, and results of operations.

If we fail to comply with government contracting regulations, we could suffer a loss of revenue or other penalties.
Some of our revenue is derived from contracts with agencies of the U.S. government and subcontracts with its prime contractors. As a result, we are subject to federal contracting regulations, including the Federal Acquisition Regulations. In connection with our business with the U.S. government, we are also subject to audits and review and approval of our policies, procedures, and internal controls for compliance with procurement regulations and applicable laws. In certain circumstances, if we do not comply with the terms of a government contract or with regulations or statutes, we could be subject to downward contract price adjustments or refund obligations or could in extreme circumstances be assessed civil and criminal penalties, or be debarred or suspended from obtaining future contracts for a specified period of time, which could have an adverse effect on our business.
Tax regulatory authorities may disagree with our positions and conclusions regarding certain tax positions resulting in unanticipated costs or non-realization of expected benefits.
A tax authority may disagree with tax positions that we have taken. For example, the Internal Revenue Service, or another tax authority could challenge our allocation of income by tax jurisdiction and the amounts paid between our affiliated companies pursuant to our intercompany arrangements and transfer pricing policies, including amounts paid with respect to our intellectual property in connection with our intercompany research and development cost sharing arrangement and legal structure. A tax authority may take the position that material income tax liabilities, interest, and penalties are payable by us, in which case, we expect that we might contest such assessment. Contesting such an assessment may be lengthy and costly and if we were unsuccessful in disputing the assessment, the implications could be materially adverse to us and affect our anticipated effective tax rate or operating income, and we could be required to pay substantial penalties and interest where applicable.
Catastrophic events may disrupt our business.
Our corporate headquarters and some of our suppliers and foundry vendors are located in areas that are in active earthquake zones or are subject to power outages, natural disasters, political, social, or economic unrest, and other potentially catastrophic events. In the event of a major earthquake, hurricane, flooding, or other catastrophic event, including with respect to climate change, such as fire, power loss, telecommunications failure, cyber-attack, war, terrorist attack, political, social, or economic unrest, pandemic, epidemic, health crisis, or disease outbreak, we may be unable to continue our operations and may endure system interruptions, reputational harm, delays in our product development, breaches of data security, or loss of critical data, any of which could have an adverse effect on our future results of operations.
State, federal, and foreign laws and regulations and other legal obligations related to privacy, data protection, and data security could adversely affect us.
We are subject to a variety of laws and regulations worldwide related to privacy, data protection, and data security, such as the European Union’s General Data Protection Regulation or California’s Consumer Privacy Act of 2018 and Privacy Rights Act of 2020. These laws and regulations are continuously and rapidly evolving, and the scope and interpretation of the laws and regulations that are or may be applicable to us are often uncertain and may be conflicting. As a result, these laws and regulations may be interpreted and applied in a manner inconsistent with our practices or policies and we could face fines, lawsuits, regulatory investigations, and other claims and penalties, and we could be required to fundamentally change our practices, which could adversely affect our business and operating results. Complying with such laws and regulations may be time-consuming and require additional resources, and could therefore adversely affect our business and results of operations. Any failure or perceived failure by us or our third-party service providers to comply with our privacy, data protection, or data security policies, or legal or contractual obligations, even if unfounded, may result in governmental enforcement actions, litigation, liability, or negative publicity, and could adversely affect our business, financial condition, and results of operations.
Security breaches, cyberattacks, and other disruptions to information technology systems owned or maintained by us or third parties, such as vendors or suppliers, could disrupt our operations, compromise the confidentiality of private customer data or our intellectual property, and adversely affect our business, reputation, operations, and financial results.
We rely on our information technology systems, and those of our vendors, suppliers, and customers, including hardware, software, cloud services, infrastructure, networks, and systems, for the effective operation of our business and for secure maintenance and storage of confidential data relating to our business. We also utilize AI tools for process automation and other efficiencies. The use of AI may increase vulnerability to cybersecurity risks, including through unauthorized use or misuse of AI tools or the introduction of malicious code incorporated into AI generated code. AI may also be used for certain cybersecurity attacks. Additionally, in the ordinary course of business we collect and store sensitive data, including intellectual property and proprietary business information as well as personal information of our customers and employees, in data centers and on information technology systems, including systems that may be controlled or maintained by third
43

Table of Contents

parties. The secure operation of these information technology systems, and the processing and maintenance of the information processed by these systems, is critical to our business operations. While we and others have implemented various controls and defenses, cybersecurity attacks and threats have continued to become more prevalent and sophisticated. These threats are constantly evolving, making it increasingly difficult to successfully defend against or implement adequate preventive measures. Geopolitical tensions or conflicts have in the past led to, and may in the future lead to, increased risk of cybersecurity attacks. Notwithstanding defensive measures, experienced programmers, hackers, state actors, or others may be able to penetrate our security controls, or those of our vendors, suppliers, or customers, through attacks such as, but not limited to, phishing or other forms of social engineering, impersonating authorized users, ransomware, spyware, viruses, worms and other malicious software programs, software supply chain attacks, exploitation of compromised commercial software, bugs and other security weaknesses and vulnerabilities, and covert introduction of malware to computers and networks. Any attack on the information technology systems of us or one of our vendors, suppliers, or customers may be difficult to detect, designed to remain dormant until a triggering event, or may continue undetected for an extended period of time. In addition, our information technology systems and those of our vendors, suppliers, and customers may be vulnerable to damage, disruptions, or shutdowns due to errors, negligence or malfeasance by employees, contractors, or others who have access to these systems.
Security breaches, cyberattacks, and other disruptions to our information technology systems or those of our vendors, suppliers, or customers could compromise the confidentiality, operational integrity, and accessibility of our information technology systems, or those of our vendors, suppliers, or customers, which could result in the compromise, unauthorized publication, or loss of proprietary data, intellectual property, or personal information, as well as interruptions or delays in our business operations, loss of existing or future customers, and damage to our reputation, which could adversely affect our business, reputation, and financial results. In addition, such events could result in violations of privacy or other laws, increase the risk of litigation or regulatory investigation, or cause us to incur direct losses if attackers initiate wire transfers or access our bank or investment accounts. We expect ongoing and increasing costs related to investments in technology, controls, processes, and practices; however these investments may not be sufficient to shield us from significant losses or liability in the event of security breaches, cyberattacks, or other disruptions to our information technology systems.
Our business may be impacted by information technology system failures or network disruptions, and lack of redundancy.
Our ability to operate our business depends on the efficient operation of internal and third-party information technology systems, including cloud computing, data centers, hardware, software, and applications, to manage our company. We strive to use quality and secure systems, work with reputable system vendors, and implement procedures intended to enable us to protect our systems.
Our information technology systems and operations could be damaged or interrupted due to events such as natural or human-caused disasters, extreme weather, geopolitical events and security issues, computer viruses, cybersecurity incidents, telecommunication failures, and similar events, which could adversely affect our business, financial condition, and results of operations. In addition, our information technology systems may not support new business models and applications, including with respect to AI, and significant investments may be required in order to upgrade such systems. Our systems are not fully redundant and depending on the severity of the damage or interruption, our disaster recovery plans may be inadequate or ineffective. These events could also damage our reputation, and result in increased costs or loss of sales.
We may not be able to utilize a significant portion of our net operating loss carryforwards and research and development tax credit carryforwards.
As of December 31, 2025, we had U.S. federal, state and foreign NOL carryforwards of approximately $344.3 million, $85.1 million and $0.2 million, respectively, and U.S. federal and state research and development tax credit carryforwards of approximately $3.9 million and $3.6 million, respectively. The U.S. federal, state, and the foreign NOL carryforwards begin to expire in 2028. The U.S. federal research and development tax credit carryforwards began to expire in 2025 and the state research and development tax credit carryforwards carry forward indefinitely. These NOL and U.S. federal tax credit carryforwards could expire unused and/or be unavailable to offset future income tax liabilities. In addition, under Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”), and corresponding provisions of California state law, if a corporation undergoes an “ownership change,” which is generally defined as a greater than 50% change, by value, in its equity ownership over a three-year period, the corporation’s ability to use its pre-change NOL carryforwards and other pre-change tax attributes to offset its post-change income may be limited. We completed a Section 382 analysis and determined an ownership change last occurred in 2014 and concluded that it had no impact on U.S. federal and California NOLs or on U.S. federal research and development credits. Our initial public offering in November 2019 and our follow-on offering on June 27, 2025 did not result in a change in ownership of greater than 50% under Section 382. We also had a follow-on offering on June 16, 2020, which resulted in greater than 50% change under Section 382. We
44

Table of Contents

completed an updated Section 382 analysis based on this new change event and determined that it will not prohibit us from eventually utilizing our carryforwards. We updated the Section 382 analysis through December 31, 2025, and concluded there have not been any additional ownership changes as defined under Section 382 since the June 16, 2020 follow-on offering. We may experience ownership changes in the future as a result of subsequent shifts in our stock ownership, some of which may be outside of our control. If we determine that an ownership change has occurred and our ability to use our historical NOL and tax credit carryforwards is materially limited, it would harm our future business, financial condition, and results of operations by effectively increasing our future tax obligations. In addition, under the Tax Act, federal NOLs incurred in 2018 and in future years may be carried forward indefinitely but generally may not be carried back and the deductibility of such NOLs is limited to 80% of taxable income. Under the Coronavirus Aid, Relief, and Economic Security Act, which was signed into law in 2020, an NOL from a tax year beginning in 2018, 2019 or 2020 can be carried back five years and would not be subject to the 80%-of-income limitation if they are exhausted during the five-year carryback period or during 2018, 2019 or 2020. We will not carry back any NOLs as they did not have taxable income in prior years.
Risks Related to Intellectual Property
Our failure to adequately protect our intellectual property rights could impair our ability to compete effectively or defend ourselves from litigation, which could harm our business, financial condition, and results of operations.
Our success depends, in part, on our ability to protect our intellectual property. We rely primarily on patent, copyright, trademark, and trade secret laws, as well as confidentiality and non-disclosure agreements, and other contractual protections, to protect our technologies and proprietary know-how, all of which offer only limited protection. The steps we have taken to protect our intellectual property rights may not be adequate to prevent the misappropriation, infringement, or other violation of our proprietary information or infringement of our intellectual property rights, and our ability to prevent such misappropriation, infringement, or other violation is uncertain, particularly in countries outside of the United States. As of March 31, 2026, we had 148 issued U.S. patents, expiring generally between 2026 and 2043, and 49 pending U.S. patent applications (including 11 provisional applications). We also had 6 foreign issued patents expiring in 2036 and 12 pending foreign patent applications. Our issued patents and pending patent applications generally relate to our MEMS fabrication process, MEMS resonators, circuits, packaging, and oscillator systems. We cannot assure you that any patents from any pending patent applications (or from any future patent applications) will be issued, and even if the pending patent applications are granted, the scope of the rights granted to us may not be meaningful or provide us with any commercial advantage. For example, these patents could be opposed, contested, circumvented, designed around by third parties, be narrowed or declared invalid or unenforceable in judicial or administrative proceedings including re-examination, inter partes review, post-grant review, interference and derivation proceedings and equivalent proceedings in foreign jurisdictions, or be subject to ownership claims by third parties. The failure of our patents to adequately protect our technology may make it easier for our competitors to offer similar products or technologies. Our foreign patent protection is less comprehensive than our U.S. patent protection and may not protect our intellectual property rights in some countries where our products are sold or may be sold in the future. Even if foreign patents are granted, effective enforcement in foreign countries may not be available. Further, we are currently unable to take advantage of selling our products online in certain countries where we do not own trademarks for our corporate name. Many U.S.-based companies have encountered substantial third-party intellectual property infringement in foreign countries, including countries where we sell products. If such an impermissible use of our intellectual property or trade secrets were to occur, our ability to sell our solutions at competitive prices may be adversely affected and our business, financial condition, and results of operations could be adversely affected.
The legal standards relating to the validity, enforceability, and scope of protection of intellectual property rights are uncertain and evolving. We cannot assure you that others will not develop or patent similar or superior technologies or solutions, or that our patents, trademarks, and other intellectual property will not be challenged, invalidated, or circumvented by others.
We also have a license to certain patents from Bosch relating to the design and manufacture of MEMS-based timing applications. The patent rights obtained under the license agreement expire between 2026 and 2029, and the license agreement expires upon expiration of the last patent licensed under the agreement. We do not believe there will be any significant impact upon expiration of these patents.
We believe that the success of our business depends more on proprietary technology, information and processes, and know-how than on our patents or trademarks. Much of our proprietary information and technology related to manufacturing processes is not patented and may not be patentable.
Unauthorized copying or other misappropriation of our proprietary technologies could enable third parties to benefit from our technologies without paying us for doing so, which could harm our business. Monitoring unauthorized use of our intellectual property is difficult and costly. It is possible that unauthorized use of our intellectual property may have
45

Table of Contents

occurred or may occur without our knowledge. We cannot assure you that the steps we have taken will prevent unauthorized use of our intellectual property, or that others will not develop technologies similar or superior to our technology or design around our intellectual property. Our failure to effectively protect our intellectual property could reduce the value of our technology in licensing arrangements or in cross-licensing negotiations.
In addition, we also rely on contractual protections with our customers, suppliers, distributors, employees, and consultants, and we implement security measures designed to protect our trade secrets and know-how. However, we cannot assure you that we have entered into such agreements with every such party, that these contractual protections and security measures will not be breached, that we will have adequate remedies for any such breach, or that our customers, suppliers, distributors, employees, or consultants will not assert rights to intellectual property or damages arising out of such contracts.
We may in the future need to initiate infringement claims or litigation in order to try to protect or enforce our intellectual property rights. Litigation, whether we are a plaintiff or a defendant, can be expensive and time-consuming and may divert the efforts of our management and other personnel, which could harm our business, whether or not such litigation results in a determination favorable to us. Litigation also puts our patents at risk of being invalidated or interpreted narrowly and our patent applications at risk of not issuing. Additionally, any enforcement of our patents or other intellectual property may provoke third parties to assert counterclaims against us. If we are unable to meaningfully protect our proprietary rights or if third parties independently develop or gain access to our or similar technologies, our business, financial condition, results of operations, reputation, and competitive position could be harmed.
We may face intellectual property infringement, misappropriation, or other claims, which could be time-consuming and costly to defend or settle and which could result in the loss of significant rights and harm our relationships with our customers and distributors.
The semiconductor industry in which we operate is characterized by companies that hold patents and other intellectual property rights and vigorously pursue, protect, and enforce intellectual property rights. From time to time, third parties may assert against us and our customers and distributors their patent and other intellectual property rights to technologies that are important to our business. Any litigation, regardless of success or merit, could cause us to incur substantial expenses, reduce our sales, and divert the efforts of our management and other personnel. In the event we receive an adverse result in any litigation, we could be required to pay substantial damages, seek licenses from third parties, which may not be available on reasonable terms or at all, cease sale of products, expend significant resources to develop alternative technology, or discontinue the use of processes requiring the relevant technology.
In addition, our commercial success depends upon our ability to manufacture and sell our products without infringing, misappropriating, or otherwise violating the intellectual property rights of others. Claims that our products, processes, or technology infringe, misappropriate, or otherwise violate third-party intellectual property rights, regardless of their merit or resolution, could be costly to defend or settle and could divert the efforts and attention of our management and other personnel. We may in the future, particularly as a public company with an increased profile and visibility, receive communications from others alleging our infringement, misappropriation, or other violation of patents, trade secrets, or other intellectual property rights. We cannot assure you that, if made, these claims will not be successful, and lawsuits resulting from such allegations, even if we believe they are invalid, could subject us to significant liability for damages, invalidate our proprietary rights, and prevent us from selling specific products. Moreover, there could be public announcements of the results of hearings, motions, or other interim proceedings or developments and if securities analysts or investors perceive these results to be negative, it could have a substantial adverse effect on the price of our common stock.
Intellectual property claims could also harm our relationships with our customers or distributors and might deter future customers from doing business with us. We do not know whether we will prevail in any such proceedings given the complex technical issues and inherent uncertainties in intellectual property litigation. If any future proceedings result in an adverse outcome, we could be required to:
• cease the manufacture, use or sale of the applicable products, processes, or technology;
• pay substantial damages for infringement by us or our customers;
• expend significant resources to develop non-infringing products, processes, or technology, which may not be successful;
• license technology from the third-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;
46

Table of Contents

• lose the opportunity to license our technology to others or to collect royalty payments based upon successful protection and assertion of our intellectual property rights against others; or
• pay substantial damages to our customers or end users to discontinue their use of or to replace infringing technology sold to them with non-infringing technology, if available.
Any of the foregoing results could adversely affect our business, financial condition, and results of operations.
Any potential dispute involving patents or other intellectual property could affect our customers, which could trigger our indemnification obligations to them and result in substantial expense to us.
In any potential dispute involving patents or other intellectual property, our customers could also become the target of litigation. Our agreements with customers and other third-parties generally include indemnification or other provisions under which we agree to indemnify or otherwise be liable to them for losses suffered or incurred as a result of claims of intellectual property infringement, damages caused by us to property or persons, or other liabilities relating to or arising from our solutions included in their products. Large indemnity payments or damage claims from contractual breach could harm our business, financial condition, and results of operations. From time to time, customers may require us to indemnify or otherwise be liable to them for breach of confidentiality or failure to implement adequate security measures with respect to their intellectual property and trade secrets. Although we normally contractually limit our liability with respect to such obligations, we may still incur substantial liability related to them. Any litigation against our customers could trigger technical support and indemnification obligations under some of our agreements, which could result in substantial expense to us.
In addition, other customers, or end customers with whom we do not have formal agreements requiring us to indemnify them may ask us to indemnify them if a claim is made as a condition to awarding future design wins to us. Because some of our customers are larger than we are and have greater resources than we do, they may be more likely to be the target of an infringement claim by third parties than we would be, which could increase our chances of becoming involved in a future lawsuit. If any such claims were to succeed, we might be forced to pay damages on behalf of our customers that could increase our expenses, disrupt our ability to sell our solutions and reduce our revenue and profit. Any dispute with a customer with respect to such obligations could have adverse effects on our relationship with that customer and other current and prospective customers and reduce demand for our solutions. In addition to the time and expense required for us to supply support or indemnification to our customers, any such litigation could severely disrupt or shut down the business of our customers, which in turn could hurt our relations with our customers and cause the sale of our products to decrease. Any of the foregoing could harm our business, financial condition, and results of operations.
Risks Related to Concentration of Ownership in Our Common Stock
As long as a limited number of stockholders hold a significant amount of our stock, our other stockholders’ ability to influence matters requiring stockholder approval will be limited.
Based on the latest filings with the SEC, holders of 5% or more of our common stock and their affiliates, beneficially owned approximately 46.7% of the outstanding shares of our common stock, based on the number of shares outstanding as of March 31, 2026. As a result, this group of stockholders has the ability to significantly influence us through this ownership position.
For example, as long as this group of stockholders continue to hold a significant or the largest ownership position in our outstanding common stock, they may have the ability to affect the outcome of any stockholder vote during this period. As a result, they will have the ability to exert significant influence over many matters affecting us, either through a board representative or as a stockholder, including:
• determinations with respect to our business plans and policies, including the appointment and removal of our officers;
• any determinations with respect to mergers and other business combinations;
• our acquisition or disposition of assets;
• our financing activities;
• the payment of dividends on our common stock; and
• the number of shares available for issuance under our stock plans.
Significant ownership position of these stockholders may discourage transactions involving a change of control of us, including transactions in which other holders of our common stock might otherwise receive a premium for their shares over
47

Table of Contents

the then current market price. In addition, as a result of this significant influence, persons who we would like to invite to join our board of directors may decline to do so.
Risks Related to Our Common Stock
Substantial future sales of our common stock could cause the market price of our common stock to decline.
The market price of our common stock could decline as a result of substantial sales of our common stock, particularly sales by our directors, executive officers, and significant stockholders, including MegaChips, or the perception in the market that a large number of stockholders intend to sell their shares. Following the anticipated closing of the Acquisition, Renesas is expected to be a significant stockholder of our common stock. The sale or potential sale of a substantial number of shares of our common stock by Renesas, or the perception that such sales could occur, could adversely affect the market price of our common stock.
Anti-takeover provisions in our charter documents and under Delaware law could make an acquisition of us more difficult, limit attempts by our stockholders to replace or remove our current management and limit the market price of our common stock.
Provisions in our certificate of incorporation and bylaws may have the effect of delaying or preventing a change of control or changes in our management. Our amended and restated certificate of incorporation and bylaws include provisions that:
• authorize our board of directors to issue, without further action by the stockholders, shares of undesignated preferred stock with terms, rights, and preferences determined by our board of directors that may be senior to our common stock;
• require that any action to be taken by our stockholders be effected at a duly called annual or special meeting and not by written consent;
• specify that special meetings of our stockholders can be called only by our board of directors, the Chairman of our board of directors, or our Chief Executive Officer;
• establish an advance notice procedure for stockholder proposals to be brought before an annual meeting, including proposed nominations of persons for election to our board of directors;
• establish that our board of directors is divided into three classes, with each class serving three-year staggered terms;
• prohibit cumulative voting in the election of directors;
• provide that our directors may be removed only for cause;
• provide that vacancies on our board of directors may be filled by a majority of directors then in office, even if less than a quorum; and
• require the approval of our board of directors or the holders of at least 66 2/3% of our outstanding shares of capital stock to amend our bylaws and certain provisions of our certificate of incorporation.
These provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace members of our board of directors, which is responsible for appointing the members of our management. 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. Any delay or prevention of a change of control transaction or changes in our management could cause our stock price to decline.
Our bylaws designate the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders, and federal district courts will be the sole and exclusive forum for Securities Act claims, which could limit our stockholders’ ability to obtain what they believe to be a favorable judicial forum for disputes with us or our directors, officers, or other employees.
Our bylaws provide that, unless we consent in writing to the selection of an alternative forum, to the fullest extent permitted by law, the Court of Chancery of the State of Delaware shall be the sole and exclusive forum for (a) any derivative action or proceeding brought on our behalf, (b) 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, (c) any action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law, our certificate of incorporation or our bylaws, or (d)
48

Table of Contents

any action asserting a claim against us governed by the internal affairs doctrine. Section 27 of the Securities Exchange Act of 1934, or the Exchange Act, creates exclusive federal jurisdiction over all suits brought to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder. As a result, the exclusive forum provision will not apply to suits brought to enforce any duty or liability created by the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction. Our bylaws further provide that, unless we consent in writing to the selection of an alternative forum, the federal district courts are the sole and exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act.
Any person or entity purchasing or otherwise acquiring any interest in our capital stock shall be deemed to have notice of and consented to the provisions of our bylaws described above. This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers, or other employees, which may discourage such lawsuits against us and our directors, officers, or other employees. Alternatively, if a court were to find these provisions of our bylaws inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving such matters in other jurisdictions, which could adversely affect our business, financial condition, and results of operations and result in a diversion of the time and resources of our management and board of directors.
Our stock price may be volatile and may decline, resulting in a loss of some or all of our stockholder investment.
The trading price and volume of our common stock is likely to be volatile and could fluctuate significantly in response to numerous factors, many of which are beyond our control, including:
• macroeconomic conditions;
• actual or anticipated fluctuations in our results of operations due to, among other things, changes in customer demand, product life cycles, pricing, ordering patterns, and unforeseen operating costs;
• the financial projections we may provide to the public, any changes in these projections, or our failure to meet these projections;
• failure of securities analysts to initiate or maintain coverage of us, changes in financial estimates or ratings by any securities analysts who follow us, or our failure to meet these estimates or the expectations of investors;
• announcements by our significant customers of changes to their product offerings, business plans, or strategies;
• announcements by us or our competitors of significant technical innovations, acquisitions, strategic partnerships, joint ventures, or capital commitments;
