Risk factors and legal proceedings

The risks Cytek Biosciences, Inc. names in Item 1A of its 10-K filed Feb 26, 2026: 74 risks under these headings, as written.5

  • Risks Related to Our Business and Strategy
  • We have a limited operating history and only recently launched our commercial products, which may make it difficult to evaluate the prospects for our future viability and predict our future performance. We have limited experience marketing and selling our products.
  • We are highly dependent on a limited number of product offerings. Our revenue has been primarily generated from sales of our core Cytek Aurora, Northern Lights, Cytek Aurora CS, and Cytek Aurora Evo systems, which require a substantial sales cycle and are prone to quarterly fluctuations in revenue.
  • We currently rely on single source suppliers and, in some cases, sole source suppliers, for certain components and materials used in our systems and may not be able to find replacements or immediately transition to alternative suppliers, which could have an adverse effect on our business, financial condition and results of operations.
  • Our results of operations will be harmed if we are unable to accurately forecast customer demand for our products and manage our inventory.
  • International operations and expansion of our international business expose us to business, regulatory, political, operational, financial and economic risks associated with doing business outside of the United States.
  • Tariffs or other government trade policies may materially adversely affect our business and results of operations, including by reducing demand for our products.
  • We are subject to governmental export controls and sanctions programs that could impair our ability to compete in international markets due to licensing requirements and subject us to liability if we are not in compliance with applicable laws.
  • We have limited experience manufacturing our products, and if we are unable to manufacture our products in high-quality commercial quantities successfully and consistently to meet demand, our growth will be limited.
  • Our future success is dependent upon our ability to increase penetration in our existing markets and expand into adjacent markets.
  • Our business is dependent on adoption of our products by academic and government institutions, CROs, pharmaceutical companies and clinical laboratories for their research and development activities focused on cell analysis. If academic and government institutions, CROs, pharmaceutical companies and clinical laboratories are
  • unwilling to change current practices to adopt our products, it will negatively affect our business, financial condition, prospects and results of operations.
The other 63 risks
  • Our business currently depends significantly on research and development spending by academic and government-owned institutions, a reduction in which could limit demand for our solutions and adversely affect our business and operating results.
  • We rely on distributors for sales of our products in certain geographies outside of the United States. If we are unable to secure additional distributors or maintain good relationships with our existing distributors, or if such distributors do not perform adequately or effectively, our business could suffer.
  • The market for cell analysis technologies and life sciences tools, including flow cytometry, is highly competitive, and if we cannot compete successfully with our competitors, we may be unable to increase or sustain our revenue, or achieve and sustain profitability.
  • Our future success depends on our ability to develop and successfully introduce new and enhanced products that meet the needs of our customers.
  • If we are unable to successfully develop new products, adapt to rapid and significant technological change, respond to introductions of new products by competitors, make strategic and operational decisions to prioritize certain markets, technology offerings or partnerships, and develop and capitalize on markets, technologies or partnerships, our business could suffer.
  • New product development involves a lengthy and complex process and we may be unable to develop or commercialize products on a timely basis, or at all.
  • Our instruments are complex in design and may contain defects that are not detected until deployed by our customers, which could increase our costs and reduce our net sales. If our products do not perform as expected or the reliability of the technology on which our products and services are based is questioned, our operating results, reputation and business will suffer.
  • We may acquire other businesses or form other joint ventures or make investments in other companies or technologies that could negatively affect our operating results, dilute our stockholders’ ownership, increase our debt or cause us to incur significant expense.
  • Shipping is a critical part of our business and any changes in our shipping arrangements or damages or losses sustained during shipping could adversely affect our business, financial condition, results of operations and prospects.
  • If we are unable to successfully expand our commercial operations, including hiring additional qualified sales representatives, technical applications specialists and customer support staff, our business may be adversely affected.
  • If we are unable to expand or leverage the number of peer-reviewed articles published using data generated by our products or otherwise increase brand awareness, the demand for our products and our business may be adversely affected.
  • We are highly dependent on our senior management team and key personnel and our business could be harmed if we are unable to attract and retain personnel necessary for our success.
  • We have increased the size of our organization and expect to further increase it in the future, and we may experience difficulties in managing our growth. If we are unable to manage the anticipated growth of our business, our future revenue and operating results may be harmed.
  • If we fail to maintain an effective system of internal controls, we may not be able to accurately or timely report our financial condition or results of operations.
  • We may need to raise additional capital to fund our existing operations, develop our products and/or expand our operations.
  • Our operating results may fluctuate significantly, which makes our future operating results difficult to predict and could cause our operating results to fall below expectations or any guidance we may provide.
  • The sizes of the markets for our products may be smaller than we estimate.
  • If we were to be sued for product liability, we could face substantial liabilities that exceed our resources, limit sales of our existing products and limit commercialization of any products that we may develop.
  • Litigation and other legal proceedings may harm our business.
  • If our information technology systems or data, or those of third parties with whom we work, are compromised, now or in the future, we could experience adverse consequences resulting from such a compromise, including but not limited to regulatory investigations or actions; litigation; fines and penalties; disruptions of our business operations; reputational harm; loss of revenue or profits; loss of customers or sales; and other adverse consequences.
  • Business disruptions could seriously harm our future revenue and financial condition and increase our costs and expenses.
  • Our insurance policies are expensive and protect us only from some business risks, which leaves us exposed to significant uninsured liabilities.
  • We use hazardous biological materials that require considerable expertise for handling, storage and disposal and may result in claims against us. We and third parties with whom we contract must comply with environmental laws and
  • regulations, which can be expensive and restrict how we do business, and could expose us to liability if our use of such hazardous materials cause injury.
  • We are subject to foreign currency exchange risk.
  • Risks Related to Government Regulation and Our Industry
  • Our products may become subject to more onerous regulation by the FDA or other regulatory agencies in the future, which could increase our costs and delay or prevent sales of our products or commercialization of new products and product enhancements, thereby materially and adversely affecting our business, financial condition, results of operations and prospects.
  • We and our suppliers are subject to ongoing regulatory obligations and continued regulatory review, which may result in significant additional expense and subject us to penalties if we fail to comply with applicable regulatory requirements.
  • Our products or any component thereof may be subject to product recalls in the future. A recall of our products, either voluntarily or at the direction of the FDA or another governmental authority, or the discovery of serious safety issues with our products, could have a significant adverse impact on us.
  • The misuse or off-label use of our products may harm our reputation in the marketplace, or result in injuries that lead to product liability suits, which could be costly to our business. Moreover, we could be subject to FDA sanctions if we are deemed to have engaged in off-label promotion.
  • We are subject to U.S. and certain foreign anti-corruption and anti-money laundering laws and regulations. We can face criminal liability and other serious consequences for violations, which can harm our business.
  • Disruptions at the FDA, the SEC, and other government agencies and regulatory authorities from funding cuts, personnel losses, regulatory reform, government shutdowns, and other developments could hinder their ability to hire and retain key leadership and other personnel, prevent new products and services from being developed or commercialized in a timely manner, or otherwise prevent those agencies from performing normal business functions on which the operation of our business may rely, which could negatively impact our business.
  • Issues in the development and use of artificial intelligence technologies, combined with an uncertain regulatory environment, may result in reputation harm, liability, or other adverse consequences to our business operations.
  • If we fail to comply with U.S. federal and state fraud and abuse and other healthcare laws and regulations, including those relating to kickbacks and false claims, we could face substantial penalties and our business operations and financial condition could be harmed.
  • Our employees, independent contractors, consultants, commercial partners and vendors may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements, which could harm our business, financial condition and results of operations.
  • Risks Related to Our Intellectual Property
  • If we are unable to obtain and maintain patent or other intellectual property protection for any of our current or future products, or if the scope of the patent and other intellectual property protection obtained is not sufficiently broad, our competitors could develop and commercialize products similar or identical to ours, and our ability to successfully commercialize our current or future products may be harmed.
  • Patents covering our current, and any future, products or our technologies could be found invalid or unenforceable if challenged in court or before administrative bodies in the United States or abroad, which could harm our business, financial condition and results of operations.
  • We rely substantially on our trademarks and trade names. If our trademarks and trade names are not adequately protected, then we may not be able to build name recognition in our markets of interest and our business may be harmed.
  • Obtaining and maintaining our intellectual property, including patent, protection depends on compliance with various procedural, document submission, fee payment and other requirements imposed by government agencies, and our intellectual property, including patent, protection could be reduced or eliminated for non-compliance with these requirements.
  • We have limited foreign intellectual property rights outside the United States, selected countries in the European Union, the UK, Japan, and China and may not be able to protect our intellectual property and proprietary rights throughout the world, which could harm our business, financial condition and results of operations.
  • Changes in U.S. patent law could diminish the value of patents in general, thereby impairing our ability to protect our current and any future products.
  • Third-party claims of intellectual property infringement, misappropriation or other violation against us, the joint-owners of our intellectual property, or our collaborators may prevent or delay the sale and marketing of our current and any future products.
  • We may become involved in lawsuits to protect or enforce our patents and other intellectual property rights, which could be expensive, time-consuming and unsuccessful.
  • We may be subject to claims that our employees, consultants or advisors have wrongfully used or disclosed alleged trade secrets of their current or former employers or claims asserting ownership of what we regard as our own intellectual property. Such claims could harm our business, financial condition and results of operations.
  • If we are unable to protect the confidentiality of our trade secrets, our business and competitive position would be harmed.
  • Failure of a key information technology system, process, or site could have an adverse effect on our business.
  • Our use of open source software could compromise our ability to offer our services and subject us to possible litigation.
  • Risks Related to Ownership of Our Common Stock
  • Our stock price may continue to be volatile, and our stockholders may not be able to resell shares of our common stock at or above the price they paid.
  • We have broad discretion in the use of our cash and may invest or spend the funds in ways with which you do not agree and in ways that may not yield a return.
  • Substantial future sales of shares of our common stock or securities convertible into our common stock will result in additional dilution of the percentage of ownership of our stockholders and could cause the market price of our common stock to decline.
  • Concentration of ownership of our common stock among our executive officers, directors, and principal stockholders and their respective affiliates may prevent new investors from influencing significant corporate decisions.
  • We do not intend to pay dividends for the foreseeable future and, as a result, your ability to achieve a return on your investment will depend on appreciation in the price of our common stock.
  • Our disclosure controls and procedures may not prevent or detect all errors or acts of fraud.
  • Anti-takeover provisions under our charter documents and Delaware law could delay or prevent a change of control which could limit the market price of our common stock and may prevent or frustrate attempts by our stockholders to replace or remove our current management.
  • Our amended and restated certificate of incorporation and amended and restated bylaws provide that the Court of Chancery of the State of Delaware will be the exclusive forum for substantially all disputes between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers or employees.
  • General Risk Factors
  • If our estimates or judgments relating to our critical accounting policies are based on assumptions that change or prove to be incorrect, our operating results could fall below our publicly announced guidance or the expectations of securities analysts and investors, resulting in a decline in the market price of our common stock.
  • We could be subject to securities class action litigation.
  • We have incurred and will continue to incur increased costs as a result of operating as a public company, and our management will be required to devote substantial time to compliance with our public company responsibilities and corporate governance practices.
  • Our failure to meet Nasdaq’s continued listing requirements could result in a delisting of our common stock.
  • If securities or industry analysts do not publish research or publish unfavorable or inaccurate research about our business, our common stock price and trading volume could decline.
  • Our ability to use our net operating losses (“NOLs”) to offset future taxable income may be subject to certain limitations.
  • Changes in our effective tax rate or tax liability may have an adverse effect on our results of operations.
  • Changes in tax law and regulations may have a material adverse effect on our business, financial condition and results of operations.
  • Changes and uncertainties in the tax system in the countries in which we have operations, could materially adversely affect our financial condition and results of operations, and reduce net returns to our shareholders.
