SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Annual Report on Form 10-K contains forward-looking statements about us and our industry that involve substantial risks and uncertainties. All statements other than statements of historical facts contained in this Annual Report on Form 10-K, including statements regarding our future results of operations, financial condition, business strategy and plans and objectives of management for future operations, are forward-looking statements. In some cases, you can identify forward-looking statements because they contain words such as “anticipate,” “believe,” “contemplate,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “plan,” “potential,” “predict,” “project,” “should,” “target,” “will,” “would,” “become,” “forecast,” or the negative of these words or other similar terms or expressions.

We have based these forward-looking statements largely on our current expectations and projections about future events and trends that we believe may affect our financial condition, results of operations, business strategy and financial needs. These forward-looking statements are subject to a number of risks, uncertainties, factors and assumptions described in the section titled “Risk Factors” and elsewhere in this Annual Report on Form 10-K, regarding, among other things:

our expected future growth;

the size and growth potential of the markets for our products, and our ability to serve those markets;

our ability to accurately forecast demand for our products;

general economic and market conditions, including as a result of infectious disease outbreaks, seasonal demands, regulatory matters, economic recessions or slowdowns, the ongoing war in Ukraine, conflicts in the Middle East and the general inflationary environment;

the rate and degree of market acceptance of our products;

the expected future growth of our sales and marketing organization;

the performance of, and our reliance on, third parties in connection with the commercialization of our products, including single-source suppliers and, in some cases, sole source suppliers;

our ability to accurately forecast and manufacture appropriate quantities of our products to meet commercial demand;

our ability to integrate the businesses we acquire and to achieve and recognize the anticipated benefits of the transaction;

regulatory developments in the United States and foreign countries;

our ability to retain regulatory approval for our products or obtain regulatory approval for new products in the United States and in any foreign countries in which we make seek to do business;

our research and development for existing products and any future products;

the development, regulatory approval and commercialization of competing products;

our ability to retain and hire senior management and key personnel;

our ability to develop and maintain our corporate infrastructure, including our ability to maintain an effective system of internal controls;

our financial performance and capital requirements; and

our expectations regarding our ability to obtain and maintain intellectual property protection for our products, as well as our ability to operate our business without infringing the intellectual property rights of others.

These risks are not exhaustive. Other sections of this Annual Report on Form 10-K may include additional factors that could harm our business and financial performance. We operate in a very competitive and rapidly changing environment where new risk factors may emerge from time to time, and it is not possible for our management to predict all risk factors, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in, or implied by, any forward-looking statements.

You should not rely on forward-looking statements as predictions of future events. We have based the forward-looking statements contained in this Annual Report on Form 10-K primarily on our current expectations and projections about future events and trends that we believe may affect our business, financial condition and operating results. These forward-looking statements speak only as of the date of this annual report. We undertake no obligation to update any forward-looking statements made in this Annual Report on Form 10-K to reflect events or circumstances after the date of this Annual Report on Form 10-K or to reflect new information or the occurrence of unanticipated events, except as required by law. We may not actually achieve the plans, intentions or expectations disclosed in our forward-looking statements, and you should not place undue reliance on our forward-looking statements. Our forward-looking statements do not reflect the potential impact of any future acquisitions, mergers, dispositions, joint ventures or investments.

In addition, statements that “we believe” and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based on information available to us as of the date of this Annual Report on Form 10-K. While we believe that information provides a reasonable basis for these statements, that information may be limited or incomplete. Our statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all relevant information. These statements are inherently uncertain, and investors are cautioned not to unduly rely on these statements.

Unless the context indicates otherwise, as used in this Annual Report on Form 10-K, the terms “Company,” “Cytek,” “Registrant,” “we,” “us” and “our” refer to Cytek Biosciences, Inc., a Delaware corporation, and its direct and indirect subsidiaries, taken as a whole.

“Cytek,” “Cytek Aurora,” “Northern Lights,” “NL-CLC,” “Cytek Orion,” “Amnis,” “Guava,” “ImageStream,” “Muse,” “easyCyte,” “Tonbo,” “cFluor,” “SpectroFlo,” “SpectroPanel,” “SpectroPrep,” “InCyte,” “GuavaLink,” “IDEAS,” “Similarity,” “Complexity,” “FSP,” “Full Spectrum Profiling,” “ESP,” “Enhanced Small Particle” and “DxP Athena” are trademarks of the Company. All other service marks, trademarks and trade names appearing in this Annual Report on Form 10-K are the property of their respective owners. We do not intend our use or display of other companies’ trade names, trademarks or service marks to imply a relationship with, or endorsement or sponsorship of us by, these other companies. Solely for convenience, the trademarks and trade names referred to in this Annual Report on Form 10-K may appear without the ® and™ symbols, but those references are not intended to indicate, in any way, that we will not assert, to the fullest extent under applicable law, our rights, or the right of the applicable licensor to these trademarks and trade names.
