First Quarter 2025 Financial Results

Total revenue for the first quarter of 2025 was $41.5 million, a 7.6% decrease compared to the first quarter of 2024. The decrease in revenue reflected a slowdown in product sales in the US and EMEA, partially offset by strength in APAC and strong service revenue worldwide.

Gross profit was $20.2 million for the first quarter of 2025, a 12% decrease compared to the first quarter of 2024. GAAP gross profit margin was 49% in the first quarter of 2025 compared to 51% in the first quarter of 2024. Adjusted gross profit margin, after adjusting for stock-based compensation expense and amortization of acquisition-related intangibles, was 52% in the first quarter of 2025 compared to 55% in the first quarter of 2024.

Operating expenses were $35.1 million for the first quarter of 2025, a 4.1% increase from $33.7 million in the first quarter of 2024.

Research and development expenses were $9.7 million for the first quarter of 2025 compared to $9.8 million for the first quarter of 2024.

Sales and marketing expenses were $12.5 million for the first quarter of 2025 compared to $12.5 million for the first quarter of 2024.

General and administrative expenses were $12.9 million for the first quarter of 2025 compared to $11.4 million for the first quarter of 2024.

Loss from operations in the first quarter of 2025 was $15.0 million compared to loss from operations of $10.7 million in the first quarter of 2024. Net loss in the first quarter of 2025 was $11.4 million compared to a net loss of $6.2 million in the first quarter of 2024.

Adjusted EBITDA loss in the first quarter of 2025 was $3.3 million compared to a loss of $0.7 million in the first quarter of 2024, after adjusting for stock-based compensation expense and foreign currency exchange impacts. Excluding investment income, Adjusted EBITDA loss for the first quarter was $5.5 million compared to a loss of $2.6 million in the first quarter of 2024.

Cash and marketable securities were $265.6 million as of March 31, 2025, compared to $277.9 million as of December 31, 2024. This represents a decrease of $12.3 million, despite a cash expenditure of $10.6 million for the repurchase of Cytek shares during the first quarter.

2025 Outlook

Cytek Biosciences revises its 2025 revenue guidance of full year 2025 revenue to be in the range of $196 million to $210 million, representing growth of -2% to 5% over full year 2024, assuming no change in 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, 2025 and March 31, 2024. Management believes that non-GAAP financial measures, including “Adjusted gross profit margin,” “Adjusted EBITDA loss,” and “Adjusted EBITDA loss excluding investment income,” referenced above, 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.
