Cytek Biosciences Reports First Quarter 2023 Financial Results

FREMONT, Calif., May 9, 2023 (GLOBE NEWSWIRE) — Cytek^® Biosciences, Inc. (“Cytek Biosciences” or “Cytek”) (Nasdaq: CTKB) today reported financial results for the first quarter ended March 31, 2023.

First Quarter Highlights

“While we saw strong growth across Europe and APAC during the first quarter, with notable strength in China, we experienced softness with our pharma and biotech customer base in the U.S., particularly at the end of the quarter. Despite these headwinds, we firmly believe the underlying opportunity for our novel FSP platform remains strong,” said Dr. Wenbin Jiang, CEO of Cytek Biosciences. “At the end of February, we completed the acquisition of product lines from the Luminex flow cytometry and imaging business, which provide important contributions to our technological capabilities, product range, customer base and commercial reach. We are excited for the expected contributions and leverage from this acquisition as it expands both the technologies Cytek can provide and the breadth of the customer base we can reach with our complete cell analysis solutions.”

First Quarter 2023 Financial Results

Total revenue for the first quarter of 2023 was $37.1 million, a 6% increase over the first quarter of 2022. This included $3.4 million of revenue from the Luminex acquisition, which closed on February 28, 2023. Excluding revenue from this acquisition, organic revenue was $33.7 million, a 4% decline compared to the same period of the prior year. The decline in organic revenue was related to weakness in the U.S, particularly with pharmaceutical and biotech customers, which was partially offset by stronger revenue growth across the EMEA and APAC regions. On a constant currency basis, total revenue for the first quarter of 2023 was $38.1 million, a 9% increase over the first quarter of 2022.

Gross profit was $21.0 million for the first quarter of 2023, an increase of 4% compared to a gross profit of $20.2 million in the first quarter of 2022. Gross profit margin was 57% in the first quarter of 2023 compared to 58% in the first quarter of 2022. Adjusted gross profit margin, after adjusting for stock-based compensation expense and amortization of acquisition-related intangibles, was 59% in the first quarter of 2023 compared to 60% in the first quarter of 2022.

Operating expenses were $33.2 million for the first quarter of 2023, a 47% increase from $22.5 million in the first quarter of 2022. The increase was primarily due to expenses to support continued growth of the business, including further investments in R&D, sales and marketing and G&A, with increases in headcount and personnel-related expenses, costs related to the acquisition, and infrastructure services to support the growth of our overall operations.

Research and development expenses were $10.0 million dollars for the first quarter of 2023 compared to $8.0 million dollars for the first quarter of 2022.

Sales and marketing expenses were $11.1 million dollars for the first quarter of 2023 compared to $7.0 million dollars for the first quarter of 2022.

General and administrative expenses were $12.1 million dollars for the first quarter of 2023, an increase from $7.5 million dollars for the first quarter of 2022.

Loss from operations in the first quarter of 2023 was $12.2 million compared to loss from operations of $2.4 million in the first quarter of 2022. Net loss in the first quarter of 2023 was $6.8 million compared to a net loss of $2.2 million in the first quarter of 2022.

Adjusted EBITDA in the first quarter of 2023 was $(2.5) million compared to $1.9 million in the first quarter of 2022, after adjusting for stock-based compensation expense and foreign currency exchange impacts.

Cash, cash equivalents, and short term investments in marketable securities were approximately $299.0 million as of March 31, 2023, compared to $341.0 million as of December 31, 2022. This includes an aggregate cash consideration of $44.9 million related to the purchase Luminex’s flow cytometry and imaging assets on February 28, 2023.

2023 Outlook

As a result of macro-economic uncertainties causing longer sales cycles, Cytek Biosciences has revised its full year 2023 revenue outlook and now expects total revenue to be in the range of $205 million to $220 million, representing growth of 25% to 34% over full year 2022. This includes an expected revenue contribution in the range of $25 million to $30 million from the acquisition of Luminex’s flow cytometry and imaging business, which closed on February 28, 2023.

Statement Regarding Use of Non-GAAP Financial Information

Cytek has presented certain financial information in accordance with U.S. GAAP and also on a non-GAAP basis for the three-month periods ended March 31, 2023 and March 31, 2022. Management believes that non-GAAP financial measures, including “Adjusted gross profit margin,” “Adjusted EBITDA” and revenue on a “constant currency basis” 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. Cytek calculates constant currency revenue growth rates by applying the prior period weighted average exchange rates to current period results. Cytek presents constant currency information to provide a framework for assessing how our underlying business performed excluding the effect of foreign currency rate fluctuations. 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.
