## Exhibit 99.1

**Exhibit 99.1** 

**Cytek Biosciences Reports Second Quarter 2025 Financial Results** 

**FREMONT, Calif., August 6, 2025** (GLOBE NEWSWIRE) – Cytek<sup>®</sup> Biosciences, Inc. ("Cytek Biosciences" or "Cytek") (Nasdaq: CTKB), a leading cell analysis solutions company, today reported financial results for the second quarter ended June 30, 2025.

**Second Quarter Highlights** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Total revenue for the second quarter of 2025 was $45.6 million, representing a 2% decrease compared to the
second quarter of 2024

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Expanded to a total installed base of 3,295 Cytek instruments, adding 146 units in the second quarter of 2025,
and representing 3% unit growth of Cytek FSP<sup>®</sup> instruments compared to the second quarter of 2024

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Launched the Cytek Aurora<sup>™</sup> Evo system, a new full
spectrum flow cytometer that improves on its flagship Cytek Aurora system and offers faster sample throughput, automated instrument startup and shutdown, enhanced resolution for small particle detection, and data harmonization

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Total recurring revenue, comprised of service and reagent revenues, grew 16% compared to the second quarter of
2024 and accounts for 32% of last 12 months' total revenue

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Repurchased $4.5 million of Cytek common stock in open market purchases during the second quarter of 2025

"The progress we achieved in the first half of this year is underscored by steady growth in our FSP unit placements, and in our recurring revenue businesses, despite a macro environment that remains challenging. I am also proud of our team's continued focus on innovation and the launch of the Cytek Aurora Evo system, which we believe will accelerate broader adoption of our solutions," said Dr. Wenbin Jiang, CEO of Cytek Biosciences.

Dr. Jiang continued, "Looking ahead, we remain focused on expanding our installed base globally, which supports our parallel goal of growing our recurring revenue through our service and reagent businesses. Further, we plan to continue strengthening our market leadership through innovation that redefines industry standards and creates new markets. We expect the instrument market to recover over time and are poised to emerge in an even stronger position than we are today with a focus on these longer-term growth drivers for our business."

**Second Quarter 2025 Financial Results** 

Total revenue for the second quarter of 2025 was $45.6 million, a 2% decrease compared to the second quarter of 2024. The decrease in revenue was due to lower product revenue in EMEA and APAC, partially offset by growth in service revenue worldwide, and the U.S. product revenue.

GAAP gross profit was $23.9 million for the second quarter of 2025, a 6% decrease compared to the second quarter of 2024. GAAP gross profit margin was 52% in the second quarter of 2025, compared to 55% in the second quarter of 2024. Adjusted gross profit margin, after adjusting for stock-based compensation expense and amortization of acquisition-related intangibles, was 56% in the second quarter of 2025, compared to 58% in the second quarter of 2024.

------

Operating expenses were $34.5 million for the second quarter of 2025, a 2% increase compared to the second quarter of 2024.

Research and development expenses were $8.8 million for the second quarter of 2025, a 12% decrease compared to the second quarter of 2024.

Sales and marketing expenses were $12.1 million for the second quarter of 2025, a 1% decrease compared to the second quarter of 2024.

General and administrative expenses were $13.5 million for the second quarter of 2025, a 16% increase compared to the second quarter of 2024.

Loss from operations in the second quarter of 2025 was $10.6 million, compared to loss from operations of $8.5 million in the second quarter of 2024. Net loss in the second quarter of 2025 was $5.6 million, compared to a net loss of $10.4 million in the second quarter of 2024.

Adjusted EBITDA in the second quarter of 2025 was $1.3 million, compared to $2.9 million in the second quarter of 2024, after adjusting for stock-based compensation expense and foreign currency exchange impacts. Excluding investment income, Adjusted EBITDA for the second quarter was a loss of $0.8 million, compared to positive $1.0 million in the second quarter of 2024.

Cash and marketable securities were $262.0 million as of June 30, 2025, compared to $265.6 million as of March 31, 2025. This represents a decrease of $3.6 million, despite a cash expenditure of $4.5 million for the repurchase of Cytek shares during the second quarter.

**2025 Outlook** 

Cytek Biosciences narrows its 2025 revenue guidance of full year 2025 revenue to be in the range of $196 million to $205 million, representing growth of -2% to +2% over full year 2024, assuming no change from current currency exchange rates.

**Statement Regarding Use of Non-GAAP Financial Information** 

Cytek has presented certain financial information in accordance with generally accepted accounting principles in the United States ("U.S. GAAP") and also on a non-GAAP basis for the three-month period ended June 30, 2025 and June 30, 2024. Management believes that non-GAAP financial measures, including "Adjusted gross profit," "Adjusted gross profit margin," "Adjusted EBITDA," and "Adjusted EBITDA excluding investment income," referenced in this release, taken in conjunction with GAAP financial measures, provide useful information for both management and investors by excluding certain non-cash and other expenses that are not indicative of the company's core operating results.

Cytek encourages investors to carefully consider its results under GAAP, as well as its supplemental non-GAAP information and the reconciliation between these presentations, to more fully understand its business.
