**Cytek Biosciences Reports Fourth Quarter and Full Year 2025 Financial Results**

**and Provides 2026 Outlook**

**FREMONT, Calif., February 26, 2026** (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 fourth quarter and year ended December 31, 2025.

**Fourth Quarter and Full Year 2025 Highlights** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Total revenue for the fourth quarter was $62.1 million, an 8% increase compared to the fourth quarter of
2024, and the highest quarterly revenue achieved historically at Cytek

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Total revenue for the full year 2025 was $201.5 million, a 1% increase compared to the full year 2024

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Total recurring revenue, comprised of service and reagent revenues, grew 21% in 2025 compared to 2024, reaching
34% of total revenue

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Adjusted EBITDA in the year ended December 31, 2025 was $5.0 million, compared to $22.4 million
for the full year 2024

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Expanded to a total installed base of 3,664 Cytek instruments, with 630 total instruments placed during 2025.
Unit placements of Cytek's Aurora CS system grew 22% in 2025 over the prior year.

&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 Cytek's flagship 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;• Launched the Cytek<sup>®</sup> Muse<sup>®</sup> Micro cell analyzer, which was awarded the 2025 Biotech Breakthrough Award for Drug Discovery Solution of the Year and highlights Cytek's commitment to making cell analysis accessible,
intuitive and cost-effective for laboratories of all sizes

"We were pleased by our fourth quarter revenue growth, which marked a clear acceleration versus the prior year and a continuation of the positive trends we saw earlier in 2025. Our revenue performance in the quarter was driven by strong momentum in FSP instrument sales in all major markets worldwide alongside sustained growth in our recurring revenue streams. We were especially encouraged to see improving instrument demand in both the US and EMEA," said Dr. Wenbin Jiang, CEO of Cytek Biosciences. "This broad-based execution positions us well for 2026, where our priorities will continue to focus on the growth of our high-margin recurring revenue lines, accelerating the adoption of our instrument platforms, advancing a pipeline of innovative new products, and delivering profitable, durable growth in the large cell analysis market."

**Fourth Quarter 2025 Financial Results** 

Total revenue for the fourth quarter of 2025 was $62.1 million, an 8% increase compared to the fourth quarter of 2024. The increase in revenue was due to higher revenue broadly across all major regions.

GAAP gross profit was $32.9 million for the fourth quarter of 2025, a 2% decrease compared to the fourth quarter of 2024. GAAP gross profit margin was 53% in the fourth quarter of 2025 compared to 59% in the fourth quarter of 2024. Adjusted gross profit margin, after adjusting for stock-based compensation expense and amortization of acquisition-related intangibles, was 55% in the fourth quarter of 2025, compared to 61% in the fourth quarter of 2024.

Operating expenses were $38.5 million for the fourth quarter of 2025, an increase of $7.8 million or 25.5% compared to the fourth quarter of 2024 due to increased general and administrative and sales and marketing expenses, and a non-recurring benefit of $2.6 million in the prior year quarter, offset by a reduction in research and development expenses.

Research and development expenses were $9.0 million for the fourth quarter of 2025, a 7.8% decrease compared to the fourth quarter of 2024.

Sales and marketing expenses were $13.1 million for the fourth quarter of 2025, a 10.6% increase compared to the fourth quarter of 2024.

General and administrative expenses were $16.4 million for the fourth quarter of 2025, increasing $7.3 million compared to the fourth quarter of 2024 due primarily to increased headcount, sales commission, and litigation-related expenses, and a non-recurring benefit of $2.6 million in the prior-year quarter related to a change in estimate of an adjustment to a license and royalty settlement liability.

Loss from operations in the fourth quarter of 2025 was $5.6 million compared to income from operations of $3.0 million in the fourth quarter of 2024. Net loss in the fourth quarter of 2025 was $44.1 million, compared to a net income of $9.6 million in the fourth quarter of 2024. The net loss in the fourth quarter of 2025 is primarily due to the recording of a non-cash valuation allowance against deferred tax assets of $38.1 million due to the uncertainty of realizing the associated future tax benefits, and the $5.6 million loss from operations.

Adjusted EBITDA in the fourth quarter of 2025, after adjusting for stock-based compensation expense and foreign currency exchange impacts, declined to $4.5 million compared to $12.5 million in the fourth quarter of 2024, primarily due to the $7.8 million increase in operating expenses. Excluding investment income, Adjusted EBITDA for the fourth quarter was $2.7 million, compared to $10.2 million in the fourth quarter of 2024.

Cash and marketable securities totaled $261.5 million as of December 31, 2025, compared to $261.7 million as of September 30, 2025, a decrease of $0.2 million.

**Full Year 2025 Financial Results**

Total revenue for the year ended December 31, 2025 was $201.5 million, a 1% increase compared to the year ended December 31, 2024. The increase in revenue was due to higher revenue in APAC and the US, partially offset by softness in EMEA, and rest-of-world. On a non-GAAP constant currency basis, full year 2025 revenue was $198.2 million, a decline of 1.1% compared to full year 2024 as reported.

------

GAAP gross profit was $104.5 million for the year ended December 31, 2025, a 6% decrease compared to the year ended December 31, 2024. GAAP gross profit margin was 52% for the year ended December 31, 2025 compared to 55% in the year ended December 31, 2024. Adjusted gross profit margin, after adjusting for stock-based compensation expense and amortization of acquisition-related intangibles, was 55% for the year ended December 31, 2025 compared to 59% in the year ended December 31, 2024.

Operating expenses were $144.8 million for the year ended December 31, 2025, a 10% increase compared to the year ended December 31, 2024, primarily due to higher general and administrative expense, partially offset by lower research and development expense.

Research and development expenses were $36.5 million for the year ended December 31, 2025, a 7.4% decrease compared to the year ended December 31, 2024.

Sales and marketing expenses were $49.4 million for the year ended December 31, 2025, a 0.7% increase compared to the year ended December 31, 2024.

General and administrative expenses were $58.9 million for the year ended December 31, 2025, increasing 36.7% compared to the year ended December 31, 2024, due primarily to higher patent litigation expenses, higher compensation, sales and use tax, and software expenses and a lower benefit related to the change in estimate of an adjustment to a license and royalty settlement liability.

Loss from operations for the year ended December 31, 2025 was $40.4 million compared to loss from operations of $20.5 million for the year ended December 31, 2024. Net loss for the year ended December 31, 2025 was $66.5 million compared to a net loss of $6.0 million for the year ended December 31, 2024. The increase in net loss in full year 2025 is primarily driven by a $6.6 million decline in gross profit; a $5.7 million reduction in interest expense, primarily due to a non-recurring benefit in the prior year related to the change in estimate of an adjustment to a license and royalty settlement liability; a $36.4 million increase in tax expense primarily due to the recording of a non-cash valuation allowance against deferred tax assets of $33.1 million; and a $13.2 million increase in operating expenses.

Adjusted EBITDA for the year ended December 31, 2025, after adjusting for stock-based compensation expense and foreign currency impacts was $5.0 million, compared to $22.4 million for the year ended December 31, 2024, primarily due to $6.6 million lower gross profit and $13.2 million higher operating expenses. Excluding investment income, Adjusted EBITDA for the year ended December 31, 2025 was $(3.1) million, compared to $14.4 million for the year ended December 31, 2024.

Cash and marketable securities totaled $261.5 million as of December 31, 2025 compared to $277.9 million as of December 31, 2024, a decrease of $16.4 million. The reduction in cash and marketable securities was primarily due to the Company's repurchase of approximately 3.3 million shares for $15.1 million during 2025.

**2026 Revenue Outlook** 

Cytek Biosciences initiates its 2026 revenue guidance for full year 2026 revenue to be in the range of $205 million to $212 million, representing growth of 2% to 5% over full year 2025, assuming no change in current foreign currency exchange rates or 2025 US tariff policy.

**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 and full year ended December 31, 2025 and December 31, 2024. Management believes that non-GAAP financial measures, including "Adjusted gross profit," "Adjusted gross profit margin," "Adjusted EBITDA," "Adjusted EBITDA excluding investment income," and revenue on a "constant currency basis," 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. Management uses non-GAAP measures to compare the company's performance relative to forecasts and strategic plans and to benchmark the company's performance externally against competitors. Non-GAAP information is not prepared under a comprehensive set of accounting rules and should only be used to supplement an understanding of the company's operating results as reported under U.S. GAAP. 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. Reconciliations between GAAP and non-GAAP operating results are presented in the accompanying tables of this release.
