First Quarter 2026 Financial Results

Total revenue for the first quarter of 2026 was $44.1 million, a 6% increase compared to the first quarter of 2025. The increase in revenue was driven by strong revenue performance in the US and continued growth in service and reagent revenue worldwide.

GAAP gross profit was $21.3 million for the first quarter of 2026, a 5% increase compared to the first quarter of 2025. GAAP gross profit margin was 48% in the first quarter of 2026 compared to 49% in the first quarter of 2025. Adjusted gross profit margin, after adjusting for stock-based compensation expense and amortization of acquisition-related intangibles, was 51% in the first quarter of 2026 compared to 52% in the first quarter of 2025.

Operating expenses were $39.7 million for the first quarter of 2026, a 13% increase compared to the first quarter of 2025 due to increased general and administrative expenses, partially offset by a reduction in sales and marketing and research and development expenses.

Research and development expenses were $9.6 million for the first quarter of 2026, a 1% decrease compared to the first quarter of 2025.

Sales and marketing expenses were $11.6 million for the first quarter of 2026, a 7% decrease compared to the first quarter of 2025.

General and administrative expenses were $18.5 million for the first quarter of 2026, increasing 43% compared to the first quarter of 2025 due primarily to litigation-related expenses, outside consulting expenses and bad debt reserves.

Loss from operations in the first quarter of 2026 was $18.5 million compared to loss from operations of $15.0 million in the first quarter of 2025. Net loss in the first quarter of 2026 was $18.9 million compared to a net loss of $11.4 million in the first quarter of 2025.

Adjusted EBITDA loss in the first quarter of 2026 was $9.1 million compared to an adjusted EBITDA loss of $3.3 million in the first quarter of 2025, after adjusting for stock-based compensation expense and foreign currency exchange impacts.

Cash and marketable securities totaled $262.2 million as of March 31, 2026 compared to $261.5 million as of December 31, 2025, an increase of $0.7 million.

2026 Outlook

Cytek Biosciences reaffirms its 2026 revenue guidance to be in the range of $205 million to $212 million, representing growth of 2% to 5% over full year 2025, 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 March 31, 2026 and March 31, 2025. Management believes that non-GAAP financial measures, including “Adjusted gross profit,” “Adjusted gross profit margin,” and “Adjusted EBITDA loss,” 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.
