Cytek Biosciences - Earnings Call - Q2 2025
August 6, 2025
Executive Summary
- Q2 2025 revenue of $45.6M declined 2% YoY, but improved sequentially vs Q1 ($41.5M); GAAP gross margin rose to 52% from 49% in Q1 as services and reagents grew 18% YoY each, while instruments remained pressured in EMEA/APAC.
- Versus S&P Global consensus, revenue missed by ~$0.7M (−1.6%) and GAAP EPS of −$0.04 came in below Primary EPS consensus of −$0.02; consensus based on 4 revenue and 2 EPS estimates (values from S&P Global)*.
- Full-year 2025 revenue guidance narrowed to $196–$205M (from $196–$210M in May and $204–$212M in Feb), effectively lowering the top end; management expects stronger 2H on typical back-end-weighted instrument seasonality and recurring revenue momentum.
- Product cycle catalysts include the launch of Aurora Evo (throughput, automation, small particle detection) and growing Cytek Cloud adoption (20.5k users, +27% YTD), supporting share gains even in a weak CapEx environment.
What Went Well and What Went Wrong
What Went Well
- Recurring revenue strength: service and reagent revenue each grew 18% YoY; recurring revenue reached 32% of LTM sales, providing resilience and margin support.
- U.S. outperformance and installed base growth: U.S. revenue +7% YoY; 146 instruments added in Q2, installed base reached 3,295; FSP unit volumes +3% YoY, led by Aurora analyzers.
- Innovation cadence: Aurora Evo launched with 2x throughput, automation, and small particle detection; management expects it to be margin-supportive at the high end. “We believe [Evo] will accelerate broader adoption of our solutions” (CEO).
What Went Wrong
- Instruments pressured in EMEA/APAC: EMEA total revenue −11% YoY on weaker pharma/biotech; APAC −12% YoY after a strong Q1 due to longer sales cycles.
- Gross margin below prior year: GAAP gross margin 52% vs 55% in Q2’24 (mix and one-time service parts adjustment), though up from 49% in Q1.
- Guidance trimmed at the top end: FY25 range narrowed to $196–$205M as management deems prior high end “not reasonably attainable” given market conditions.

Speaker 1
Thanks, Paul. Welcome, everyone, and thank you for your interest in Cytek. On today's call, I would like to start with a discussion of our performance in the first quarter and first half 2025, followed by an update on our full-year 2025 outlook. Next, I will give you some highlights on our progress during the second quarter on our strategic priorities for 2025 before turning the call over to Bill for a more detailed look at our financials and our outlook. Turning to slide three, our second quarter revenue in 2025 was $45.6 million, down $1 million or 2.2% compared to the second quarter of 2024. The decrease in revenue was due to lower product revenue in EMEA and APAC, partially offset by strong growth in service revenue worldwide, which grew 18%, and growth in U.S. product revenue.
This was an improvement over the first quarter of this year, with a smaller decline versus the prior year's second quarter. Turning to slide four, recurring revenue growth continued in the second quarter. Specifically, service and reagent revenue each increased by 18% versus the second quarter of 2024. Both our reagent and service businesses benefit from our established and expanding installed instrument base. In the second quarter, we continued to see these businesses contribute significant growth to our recurring revenue as a percentage of our total revenue. Our recurring revenue businesses reached 32% of trailing 12-month sales in the second quarter, growing 16% versus last year. Turning to slide five, notably, we saw 3% growth in FSP unit volume in the second quarter, led by Aurora Analyzers. We saw particular strength in the U.S., with 10% year-over-year growth.
We believe the growth in our FSP instrument unit volumes, especially in a difficult environment, speaks strongly to the overall strength of our core business and the fact that our FSP products are essential instruments to our customers' workflows, as distinguished from more discretionary instruments. Turning to slide six, looking more closely at the second quarter, total U.S. revenue was up 7% over the second quarter of 2024, driven by service and reagents. Instruments were flat in the U.S. due to growth in revenue from our pharma, biotech, and CRO customers being offset by continued softness among our academic and government customers. Still, instrument sales showed growth sequentially from the first quarter of 2025. We continued to see broad-based pressures in instrument orders from academic and government customers in the U.S., driven by a continuation from the first quarter of the uncertainties in academic funding resulting from U.S. policy change.
Coming to EMEA, we saw a different situation where overall revenue declined 11%, driven by weakness in instrument sales to our pharma, biotech, and CRO customers, offset by year-over-year growth among our academic and government customers and in service and reagents. In APAC, sales declined following a very strong performance in Q1, due primarily to the longer sales cycle we typically encounter in this region as compared to the U.S. and EMEA. However, on a longer-term basis, this region continues to demonstrate solid growth. In our rest of the world region, which includes Canada and Latin America, we delivered single-digit percentage revenue growth versus last year's second quarter.
Let me take a moment now to provide a view of our results for the first half of 2025, which we believe smoothed out some of the geographic and the end-user availability interference in our industry and provides a clearer picture of our business overall. For the first half of 2025, our total revenue was down 5% compared to last year's first half. This was comprised of weakness in EMEA, which was down 17%, and in the U.S., which was down 3%. These declines were partially offset by steady growth across APAC, which grew 9% year over year, and the rest of the world, which grew 14% since the prior year's first half. Overall, our results were supported by strength in service and reagents.
Looking at our first half revenue by customers worldwide, our academic and government revenue globally is flat compared to last year, with our pharma and biotech revenue down about 9%, largely due to weakness in EMEA. Importantly, our results in both the quarter and for the first half remind us that diversification in multiple geographical regions can combine with a growing recurring revenue stream to smooth our otherwise much more variable results. We believe the policy issues affecting our various markets in the first and second quarters will continue to exert constraints on capital equipment spending through at least the current third quarter. With the first half of the year behind us, we are now in a better position to provide guidance on full-year results. As such, we are narrowing our guidance range and now anticipate full-year 2025 revenue to be $196 million to $205 million.
Bill will provide more details on this outlook shortly. From an overall perspective, the key takeaways regarding the quarter are the fact that our core business, based on our FSP technology, continued to grow in unit volume and in revenue, and our recurring revenue businesses, including reagents and services, grew in high % ranges. We think this is a notable performance despite a challenging capital equipment spending environment. I would now like to update you on the progress our team has made across our core strategic pillars, instruments, applications, bioinformatics, and clinical, to further solidify Cytek Biosciences' position as a market leader in next-gen cell analysis solutions. Starting with our core instruments on slide seven. In the second quarter, we expanded our global footprint by 146 instruments, bringing Cytek Biosciences' total installed base to 3,295 units.
Within our instrument portfolio, our Aurora Analyzer was the strongest driver of unit growth in the second quarter. This continued core instrument growth clearly demonstrates steady expansion across a diverse customer base worldwide. To solidify our leadership position in the special flow cytometry market, we continue to prioritize innovation and delivering differentiated offerings to shape the future of the cell analysis market. In the second quarter, we announced the launch of the Cytek Aurora Evo system, setting a new standard for full spectral flow cytometry and notably improving on our flagship Cytek Aurora Analyzer that we introduced eight years ago. The Aurora Evo system has been designed to address the evolving needs of researchers and accelerate broader adoption with enhanced capabilities, including faster sample throughput, automated instrument startup and shutdown, small particle detection, and data harmonization.
We believe these enhanced features provide value through higher productivity and empower researchers to accelerate their discovery work and tackle a wider range of applications with confidence. Moving to bioinformatics on slide eight, the Cytek Cloud continues to serve a critical role for researchers. Our software tools empower customers to streamline their experiment workflow, which drives adoption and the utilization of our cell analysis solutions and the growth in our reagent and service businesses. As of June 30, 2025, we have over 20,500 Cytek Cloud users, representing a remarkable growth of 27% since the beginning of 2025. This represents an average of more than seven users per installed Cytek FSP instrument and reflects the loyalty our users have to our product portfolio and the halo effect of the Cytek Cloud driving the utilization of our technology platform.
As a reminder, our Cytek Cloud is transforming how researchers design and conduct complex flow cytometry experiments. At its core is our proprietary AI-driven panel builder, which saves weeks or months of time by automating critical steps like flow look-hold selection and marker matching. Scientists can then conduct virtual experiments before committing to real wet lab studies, reducing trial and error and improving data quality from the start. By simplifying a previously complex process, we believe that Cytek Cloud will drive broader adoption of our technology and recurring revenue opportunities across our growing installed base. Turning to our next growth pillar, applications, our intention is for the Cytek Cloud to accelerate the utilization of our reagents, which are optimized for use on our instruments. We therefore believe our reagent businesses have attractive long-term growth potential, of which we are still at the early stage.
We remain focused on driving our reagent product introduction engine, which will expand our reagent offerings and application-specific tips. We continue to make significant improvements in our reagent operations, resulting in improved execution and dramatically shorter delivery time over the past year. These enhancements have strengthened customer support and have been a key driver of the strong double-digit reagent sales growth we are seeing in the US, EMEA, and China. Importantly, we see significant room for reagent growth, both from our installed base as well as from the new instruments we sell. We estimate that our currently installed instrument base consumes at least $150 million worth of reagents annually. With our current reagent revenue capturing less than 10% of this potential, we have substantial room for reagent growth over the longer term. Over time, we expect our recurring reagent and service revenues to be key drivers of strong sustained growth.
With that, I will now turn the call over to Bill for more details about our financials.
Speaker 3
Thanks, Wenbin. Turning to slide nine in our second quarter of financial results, total revenue for Q2 was $45.6 million, a 2% decrease versus Q2 of 2024. This reflects continued weakness in instrument revenue in EMEA and APAC, offset by strong growth in service and growth in U.S. product revenue. Product revenue, which is comprised of instruments and reagents, decreased 9% versus Q2 of 2024, driven by a significant decline in EMEA. U.S. product revenue increased 2% versus Q2 of 2024. This was attributable to an increase in revenue from pharma and biotech customers, offset by weakness from academic and government customers. In EMEA, the decline in product revenue was driven by a significant decline in revenue from pharma and biotech customers, offset by an increase in revenue from academic and government customers.
APAC was weaker versus Q2 of 2024 after strong growth in Q1 and showed solid growth for the first half of 2025 versus the prior year. While our reagent revenue remains a single-digit percentage of our total revenue, it achieved its highest ever quarterly revenues in Q2, representing 18% growth over the prior year quarter. As Wenbin mentioned, this was largely due to a concerted effort by our reagents team to shorten delivery times and improve other performance metrics. Service revenue continued to deliver strong growth with 18% in Q2 versus prior year and 21% for the first half. This was driven by growth in the installed base and active usage of our systems. Turning to geographic market performance, U.S. revenue grew 7% in Q2 versus prior year, driven by service and reagent revenue growth.
EMEA declined 11% due to lower instrument revenues, partly offset by growth in services and reagents. APAC declined 12% in Q2 after a very strong Q1 and increased 9% for the first half versus prior year, driven by growth in both instruments and service revenue. GAAP gross profit was $23.9 million, a 6% decline versus Q2 of 2024. GAAP gross profit margin was 52% versus 55% in the prior year quarter due to lower product gross margin as a result of lower product revenues and lower service gross margin due to an increase in material costs, a portion of which was of a one-time nature. Overall gross margin improved from 49% in Q1 due to higher product gross margins on higher product revenues and lower manufacturing overhead.
Adjusted gross profit margin, which excludes stock-based compensation and amortization of acquisition-related intangibles, was 56% in Q2, down from 58% in the prior year quarter and up from 52% in Q1. Operating expenses were $34.5 million in Q2, up $0.5 million or 2% versus Q2 2024, driven by higher general and administrative expenses. Research and development expenses were $8.8 million, down 12% versus the year ago quarter due to lower headcount and engineering and outside services expenses. Sales and marketing expenses were $12.1 million, down 1% versus the year ago quarter. General and administrative expenses were $13.5 million, up $1.8 million or 16% from the year ago quarter. The increase was attributable to higher outside services expenses. Loss from operations was $10.6 million for Q2 versus $8.5 million in the year ago quarter, driven primarily by lower GAAP gross profit and, to a lesser extent, higher operating expenses.
Net loss was $5.6 million in Q2 versus $10.4 million in the prior year quarter. This was driven by two factors. First, net other income increased to $3.8 million versus $1.3 million in the prior year quarter. This was primarily driven by $1.6 million of foreign exchange gains in the quarter versus $1.8 million of foreign exchange losses in the prior year quarter and was offset by lower interest income of $0.9 million. Second, we had a tax benefit of $1.2 million in the current quarter as a result of a higher effective tax rate versus a tax expense of $3.2 million in the prior year quarter. Adjusted EBITDA, which excludes stock-based compensation and foreign exchange impacts, declined to $1.3 million from $2.9 million in the year ago quarter due to lower gross profit.
Positive free cash flow of $0.9 million was offset by $4.5 million of share repurchase in the quarter, decreasing our total cash and marketable securities by $3.6 million to $262 million. In the second quarter, we repurchased $4.5 million of Cytek stock or 1.2 million shares. In the first half of 2025, we repurchased $15.1 million of Cytek stock or 3.3 million shares, reducing our total shares outstanding to 127.2 million shares as of June 30. Lastly, turning to our full-year guidance on slide 10. As Wenbin mentioned earlier, we are narrowing our full-year 2025 revenue outlook. Given our first half results and the conditions prevailing in our markets, we do not believe the high end of our existing revenue guidance range for 2025 is reasonably attainable.
Accordingly, we are now guiding to a range of $196 million to $205 million, representing overall growth of -2% to +2% over full-year 2024, assuming no change from current currency exchange rates. In summary, our market leadership position remains strong, our core business is showing positive growth, and our recurring revenue continues to increase. We believe we will perform well relative to the overall flow cytometry market. Our strong balance sheet also gives us the ability to continue investing for growth. With that, I will turn it back over to Wenbin.
Speaker 1
Thanks, Bill. Turning to slide 11. Before closing, I want to thank our SciTech team for their continued commitment to delivering our industry-leading tools, reagents, and software to empower the scientific community to advance the next generation of cell analysis. I believe the progress we have achieved and the continued momentum we are building is notable while navigating a macro environment that remains challenging. Our strategy to expand our installed base globally is expected to produce growth in instrument revenue while simultaneously driving long-term sustainable recurring revenue growth in our service and reagent businesses. We further continue to strengthen our market leadership through innovation that redefines industry standards, accelerates adoption, and creates new markets. We expect the instrument market to recover over time, and we are poised to emerge in an even stronger position than we are today, with a focus on these longer-term growth drivers for our business.
I want to thank everyone for joining today's call, and we will now open it up for questions. Operator.
Speaker 2
Thank you. We will begin the question and answer session. If you would like to ask a question, please press star one on your telephone keypad. If you'd like to withdraw your question, please press star one again. Our first question comes from David Westenberg from Piper Sandler. Please go ahead.
Thank you for taking the question. I wanted to start with your performance versus the market, and just be sure that there are not maybe competitive things going on. If you can just maybe give some color on your estimate of how the flow cytometry market is performing right now and if there have been any product launches that have been of any kind of concern.
Speaker 1
We believe overall, based on the market report, we have seen the overall flow cytometry market seems reducing and going down, partially due to the funding reduction or challenge in our industry, especially for the capital expenditure. Within that domain, we continue to grow our core business. As you can see, the number of FSP instruments and actually the unit volume is going up. Yeah.
Speaker 3
That would imply that we're taking share.
Okay. Bill, maybe if I can ask you one, I know it's hard to, I know in CapEx cycles, I think it's the third month of every quarter where you normally see kind of sales. I just want to, you know, based on funnel and any other kind of experience, how comfortable are you with the second half guidance in terms of, I mean, and how much does it need the market to, say, improve, or is this kind of steady-state guidance? I realize that CapEx happens in the third month of every quarter. I know this is tough.
Our business really divides into two parts. We have the recurring revenue businesses, our service business, and our reagent business, and those have been growing high double digits. The drivers of that growth appear to be solid, and we expect that to continue. We don't see any reason why that growth rate should change significantly. We have the instrument business, which is capital spending driven, and that is obviously back-end weighted. It's heavily weighted to the third month of the quarter. We are expecting a quarterly pattern that follows that's similar to the quarterly patterns of last year. That would imply a stronger performance in the second half of the year versus the first. I also would point out that our gap to last year got significantly smaller in Q2 than it was in Q1.
We factored all those things together, and together with the market outlook, encapsulated all that and came up with our range based on those factors and that chain of reasons.
Just a comment there, Bill. Yeah, thanks so much. That was great. Maybe the last one, Wenbin, in terms of your last commentary on in a better position post-capital cycle. I know the crystal ball here is really hard, but do you think we could be with lower interest rates and maybe NIH certainty the CapEx cycle might return next year? Do you think a little bit longer than that? Finally, just on your commentary on a better position post-cycle, what do you think are going to be the big drivers of Cytek Biosciences' performance post-CapEx cycle? Thank you. I'll hop off cue after that.
Speaker 1
As you continue to invest on developing new technologies to improve the performance and to continue to launch new products, every month by the two new products we recently launched, one is our Cytek Aurora Evo, the other one is Muse Micro, one for high-end of the market applications, the other one really for the entry-level applications to serve for the customers across all the application space. We feel and we have a product, we have the technology, and we have the performance to serve for this market. When the capital expenditure challenge starts to ease, we feel and we are there to serve for the customers.
Thank you, guys.
Speaker 3
Yeah, as it relates to the macro factors that you referenced, interest rates and NIH funding certainty, we certainly saw growth rates come down as interest rates went up. We don't have a real crystal ball under how that would affect capital spending trends. One would expect that it would probably be positive, but I think in the pharma, biotech pharma industry, it's more industry-specific than interest-rate driven. With respect to the NIH, the more the clearer the funding there, obviously the better for us. Our US academic and government sector has been weaker this year, as we discussed, and more clarity on the NIH funding would help there. We know what we read in the newspapers, as it were, about those topics, and we don't have any special insight.
Speaker 2
Our next question comes from Chad Wiatkowski from TD Cowen. Please go ahead.
Hey, guys. How's it going? It's Chad on for Brendan Smith. You spoke to using the benefit of having a big balance sheet to reinvigorate growth a little bit. Obviously, nice to see a new product, but are you open to M&A at this point? If so, are there any clear white space or adjacencies you'd be open to looking at or even some non-core technologies maybe to expose yourself to some higher-end growth markets?
Speaker 3
Yeah. The short answer is yes, we are open to M&A. We continue to evaluate opportunities. We would look for opportunities that have the greatest synergy potential. By definition, that means opportunities either in our existing markets or in adjacencies, perhaps, you know, other products we can sell to the same customers. I think that's where we would primarily look for opportunities.
Speaker 1
Yeah. Actually, in addition to the M&A, we are also investing on organic growth. As you can see, our reagents, our service are growing double digit, and we continue to invest in those fields to enable us to continue to grow within our space, our sector.
Thanks for the question, guys.
Speaker 2
Our next question comes from Andrew Cooper from Raymond James. Please go ahead.
Hey, everyone. Thanks for taking the question. This is Noah on for Andrew. My first question is sort of focused on gross margins. I think you guys came in maybe a little bit shy of the numbers, and I heard you kind of talk about some of the one-time offs. Should we expect any change to cadence for gross margins for the rest of the year as those one-timers go away? Just trying to get a feel for that. Also, tariff headwinds were like 1% to 3% is what you called out last quarter. Any update there? Were those better within range? What are you seeing there as well?
Speaker 3
Sure. In terms of cadence, there are two things that affect gross margin quarter to quarter within a year. One is that our instrument revenues tend to be bigger in the third and fourth quarter than the first and second. First quarter is our weakest. Second and third are in the middle somewhere, and fourth is usually our biggest quarter. What that does is that as those instrument revenues increase, that increases our gross margin because our fixed costs remain relatively the same and would drop through more variable margin to the gross margin line. Typically, we would expect as instrument revenue goes up in the third and fourth quarter that we'll see margin improvement. The other factor is one-timers. As I mentioned, last quarter, we had a significant overhead capitalization charge that I didn't expect to continue, and it did not. That went away in the second quarter.
We wouldn't expect that to come back in the subsequent quarters. This quarter, we had an inventory adjustment primarily related to service parts. Some of that is non-recurring, and there may be. We'll get some gross margin benefit in the service business from that. I would also expect better utilization of overhead in the service business as we go through the year. I would expect improvement in both our product gross margin and our service gross margin.
Okay. Awesome. Just kind of following up more on the top line, you know, you called out biopharma strength in the US. I just kind of want to see, you know, where, like what customer segment are you seeing that from? Is that the large pharma customers looking to harmonize? Are you seeing maybe some better funding with some of the emerging guys? I know you said that the environment's still challenged, just really trying to get a feel for where there's strength and then also if you think that there might be a little bit better in the back half there, even if it's offset by EMEA.
I think the strength was really in the biopharma segment, was across the board. The big pharma customers are a much larger portion of the total pharma revenue. We saw some strength there. We also saw some strength with the small bio players, albeit that's a small portion of the total. It was really across the board. For the big pharma players, a significant advantage of our technology is the ability to harmonize it. That was an important driver and continues to be an important driver of our business with big pharma players.
Okay. Great. I'll hop off.
We also introduced the Cytek Aurora Evo, which has some important new capabilities that are highly valued by big pharma: the throughput, the automation, small particle, and so on.
Awesome. Thank you so much.
Speaker 2
Again, if you would like to ask a question, please press star number one on your telephone keypad. Our next question comes from Mason Carrito from Stevenson. Please go ahead.
Hey, this is Harrison on for Mason. Thanks for taking the questions. I wanted to ask, what contribution do you expect from Aurora Evo and the Muse Micro in 2025? Are they margin accretive? How does that compare to the core Aurora and Northern Lights?
Speaker 3
Aurora Evo is by far the larger contributor to overall revenue. It has an ASP in the hundreds of thousands, and we would expect that that's going to drive a high-end sale. That will be, let's just say, supportive of our margins. The Muse Micro is a small system that sells for less than $100,000, so it doesn't really have a big impact on margin either way. It's about a $40,000 product, something like that. Sorry, no, it's less than $20,000, so it doesn't have a big impact on margins. The Evo is a new product with advanced features, and it will be very supportive of our margins.
Okay. Got it. That's helpful. Thank you. Reagent, service, and ex-U.S. and EMEA capital sales have been growing at over a 20% year-over-year pace. Does your current guide assume those segments continue that pace in the second half here this year?
We're not going to guide to specific product lines. What you should assume or take into account is that the driver of our service growth is the driver of the installed base, the growth in the installed base with a one-year lag. If you look at the rate that our installed base grew 12 months ago, that's the best predictor that we have for the quarterly rate of growth of service revenue. We don't have a reason to expect that that's going to change significantly. Obviously, as the installed base gets bigger, that % increase with each year's deliveries comes down a little bit, but that's a gradual process. On reagents, our growth there is a function of our existing relationships with a broad set of customers through our instrument sales, our improved execution, and our broader product range.
We expect all those drivers are continuing, and we expect them to continue, that growth to continue.
Got it. Thanks for the questions.
The short answer is the drivers are all in place. The drivers are long-term drivers, and you know, they should continue to produce similar growth.
Speaker 2
There are no further questions at this time. This concludes today's conference call. Thank you for joining. You may now disconnect.
