Third Quarter 2023 Financial Results

Total revenue for the third quarter of 2023 was $48.0 million, a 19% increase over the third quarter of 2022. This included $6.8 million of revenue from the products lines acquired from Luminex on February 28, 2023. Excluding revenue from this acquisition, organic revenue was $41.2 million, a 2% increase compared to the same period of the prior year. On a constant currency basis, total revenue for the third quarter of 2023 was $47.7 million.

Gross profit was $27.2 million for the third quarter of 2023, an increase of 1% compared to a gross profit of $26.9 million in the third quarter of 2022. Gross profit margin was 57% in the third quarter of 2023 compared to 66% in the third quarter of 2022. Adjusted gross profit margin, after adjusting for stock-based compensation expense and amortization of acquisition-related intangibles, was 59% in the third quarter of 2023 compared to 68% in the third quarter of 2022.

Operating expenses were $33.6 million for the third quarter of 2023, a 32% increase from $25.5 million in the third of 2022. The increases in operating expenses were primarily due to expenses related to increased headcount from the Luminex acquisition and personnel-related expenses across sales and marketing, research and development and general administrative. These expenses included an increase in trade shows and other sales and marketing costs, and an increase in fixed assets and intangible assets amortization costs.

Research and development expenses were $11.2 million for the third quarter of 2023 compared to $8.7 million for the third quarter of 2022.

Sales and marketing expenses were $12.1 million for the third quarter of 2023 compared to $8.8 million for the third quarter of 2022.

General and administrative expenses were $10.4 million for the third quarter of 2023, an increase from $8.0 million for the third quarter of 2022.

Loss from operations in the third quarter of 2023 was $6.4 million compared to income from operations of $1.4 million in the third quarter of 2022. Net loss in the third quarter of 2023 was $6.5 million compared to a net income of $1.6 million in the third quarter of 2022.

Adjusted EBITDA in the third quarter of 2023 was $3.7 million compared to $7.3 million in the third 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 $288.0 million as of September 30, 2023, compared to $344.0 million as of December 31, 2022. The decline was primarily due to the acquisition of business lines from Luminex and Cytek’s repurchase of stock in 2023.

Please refer to Cytek’s Quarterly Report on Form 10-Q, expected to be filed with the Securities and Exchange Commission on November 9, 2023, for Cytek’s results of operations and financial condition for the third quarter of 2023.

2023 Outlook

Cytek Biosciences expects full year 2023 total revenue to be in the range of $188 million to $192 million, representing growth of 15% to 17% over full year 2022. This includes an expected revenue contribution from our organic business to be approximately flat versus 2022 and in the range of $25 million to $30 million from the Luminex flow cytometry and imaging business, which was acquired 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 September 30, 2023 and September 30, 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.
