Item 8.01 Other Events.
On August 21, 2026, the Company announced that a jury in the United States District Court for the District of Delaware returned a verdict in the patent infringement action brought by Beckman Coulter, Inc. The jury found in the Company’s favor on three of the four asserted patent claims, finding noninfringement and invalidity as to each of those three claims. With respect to one claim, the jury found no literal infringement but found infringement under the doctrine of equivalents. The jury awarded past damages consisting of $20 million in lost profits and $36.11 million in royalties. The Company intends to pursue post-verdict motions challenging the finding of infringement under the doctrine of equivalents and the related damages award.

Exhibit 99.1
Jury Finds in Cytek’s Favor on Three of Four Asserted Claims; Company to Challenge
Remaining Finding
FREMONT, Calif., August 21, 2026 (GLOBE NEWSWIRE) – Cytek Biosciences, Inc. (“Cytek Biosciences,” “Cytek,” or the “Company”) (Nasdaq: CTKB), a leading cell analysis solutions company, today announced that a jury in the United States District Court for the District of Delaware returned a verdict in the patent infringement action brought by Beckman Coulter, Inc. The jury found in Cytek’s favor on three of the four asserted patent claims, finding noninfringement and invalidity as to each of those three claims. With respect to one claim, the jury found no literal infringement but found infringement under the doctrine of equivalents. The jury awarded past damages consisting of $20 million in lost profits and $36 million in royalties. Cytek intends to pursue post-verdict motions challenging the finding of infringement under the doctrine of equivalents and the related damages award.
The verdict does not require any changes to the Company’s current product offerings or operations, and Cytek’s spectral flow cytometry products remain available to customers worldwide.
“We are pleased that the jury found in our favor on the substantial majority of claims in this case, including findings of noninfringement and invalidity as to three of the four asserted claims,” said Dr. Wenbin Jiang, CEO of Cytek Biosciences. “We fundamentally disagree with the single remaining finding and damages award and intend to pursue all available post-trial remedies, including potentially an appeal to the United States Court of Appeals for the Federal Circuit. Cytek independently developed a fundamentally different approach to flow cytometry when we pioneered Full Spectrum Profiling technology.”
Cytek will continue to invest in its proprietary and patented Full Spectrum Profiling™ platform and remains committed to delivering innovative cell analysis solutions to researchers and clinicians worldwide.

All statements other than statements of historical facts are forward-looking statements. Forward-looking statements generally can be identified by the use of forward-looking terminology such as “may,” “will,” “should,” “expect,” “plan,” “could,” “intend,” “believe,” “predict,” “potential,” or “continue” or the negatives of these terms or variations of them or similar terminology, but the absence of these words does not mean that a statement is not forward-looking. These forward-looking statements include, but are not limited to, statements regarding the Company’s expectations concerning the impact of the jury verdict and damages award, and the outcome and impact of any post-trial motions, appeals, or other proceedings related to the litigation and their potential impact; the Company’s belief in the merits of its legal positions and grounds for appeal; the potential impact of the verdict and damages award on the Company’s financial condition, results of operations, or product offerings; and the Company’s growth strategy and future financial performance. These statements are based on management’s current expectations, forecasts, beliefs, assumptions and information currently available to management, and deal with future events and involve known and unknown risks, uncertainties and other factors that may cause actual results, performance or achievements to be materially different from the information expressed or implied by these forward-looking statements. In addition, new risks and uncertainties emerge from time to time, and it is not possible for us to predict all risks and uncertainties that could have an impact on the forward-looking statements. Factors that could cause actual results to differ materially include: the impact of the jury verdict and damages award, and the outcome and impact of any post-trial motions, appeals, and further legal proceedings, including additional costs, injunctive relief, ongoing royalty obligations as determined by the court, and/or other potential liabilities; global geopolitical, economic and market conditions; and other risks discussed in the section titled “Risk Factors” set forth in the Company’s most recently filed Quarterly Report on Form 10-Q filed with the SEC on August 5, 2026, and other filings the Company makes with the SEC from time to time, which contain a discussion of important factors that may cause actual results to differ materially from those expressed or implied by the Company’s forward-looking statements. Although the Company believes that the expectations reflected in the forward-looking statements are reasonable, it cannot provide any assurance that these expectations will prove to be correct nor can it guarantee that the future results, levels of activity, performance and events and circumstances reflected in the forward-looking statements will be achieved or occur. The forward-looking statements in this press release are based on information
available to the Company as of the date hereof, and the Company disclaims any obligation to update any forward-looking statements provided to reflect any change in its expectations or any change in events, conditions, or circumstances on which any such statement is based, except as required by law.
