Howard Goldman
Good afternoon and welcome to Verix Imaging Corporation's earnings conference call for the third quarter of fiscal year 2021. With me today are Sunny Sanyal, our president and CEO, Sam Maheshwari, our CFO, and Chris Balfiore, our new director of investor relations. Before turning the call over to Chris, as many of you know, I will soon be retiring from Verix. I want to thank the Verix leadership team for the opportunity to head our investor relations mission that began several months prior to our spinoff. It's been an honor to work with all of you.
Sunny Sanyal
Chris? Thank you, Howard. Please note that the live webcast of this conference call includes a supplemental slide presentation that can be accessed from our Verix website at investors.veriximaging.com. The webcast and Supplements of SWI presentation will be archived on VERUS's website. To simplify our discussion, unless otherwise stated, all references to the quarter are for the third quarter of fiscal year 2021. In addition, unless otherwise stated, quarterly comparisons are made sequentially from the third quarter of fiscal year 2021 to the second quarter of fiscal year 2021, rather than to the same quarter of the prior year. Please be advised that during the call, we will be making forward-looking statements, which are predictions and projections about future events. These statements are based on current expectations and assumptions that are subject to risks and uncertainties that could cause actual results to differ materially from those anticipated. Risks relating to our business are described in our quarterly earnings release and our filings with the SEC. Additional information concerning factors that could cause actual results to materially differ from those anticipated is contained in our SEC filings, including item 1A, risk factors of our quarterly reports on Form 10-Q and our annual report on Form 10-K. The information in this discussion speaks as of today's date, and we assume no obligation to update or revise the forward-looking statements in this discussion. On today's call, we will discuss certain non-GAAP financial measures. These non-GAAP measures are not presented in accordance with nor are they a substitute for GAAP financial measures. We provided a reconciliation of each non-GAAP financial measure to the most directly comparable GAAP financial measure in our earnings press release, which is posted on our website. I will now turn the call over to Sonny.
Howard Goldman
Thank you. Good afternoon, everyone, and please join me in welcoming Chris Belfiore to the team. And, Howard, thank you very much for all your contributions over the last four years. We wish you all the best in your retirement. I'm pleased to report that sales momentum continued in the third quarter of fiscal 2021 with revenues reaching $211 million driven by strong demand in both medical and industrial segments. Higher sales volume and continued execution on expense management led to margin and profitability expansion in the quarter. We continue to see strong demand for CT tubes globally during the quarter, as well as robust detector sales for both medical and industrial applications. In the third quarter, all medical modalities except dental returned to pre-COVID sales levels or better. Our revenues in the third quarter increased 4% sequentially, driven mainly by gains in the medical segment. Revenues increased 23% year over year by improvement in both medical and industrial segments. Our non-GAAP gross margin increased to 36%. due to higher volume and productivity, partially offset by unfavorable product weeks. Our non-GAAP operating margin improved to 14% of revenues. As a result, non-GAAP EPS was 40 cents and exceeded the top end of our guidance range. Let me give you some high-level insight into how different modalities and applications trended during the quarter. Medical segment revenues increased 7% sequentially and 22% year-over-year. The strong trend in CT tube cells continued during the third quarter, enabling our already large installed base to grow further. Since many of these tubes were for new systems, it bodes well for our future cells related to replacement tubes. In our other medical modalities, oncology, fluoroscopy, and mammography posted healthy sequential growth and are back to or above pre-COVID levels. We believe growth in medical segment was driven in part by demand that had been deferred over the past year, as well as expansion of healthcare services in some markets and adoption of new technologies. Revenues in our industrial segment decreased 6% sequentially and increased 31% year over year. We attribute some of the sequential decline in the industrial segment to inter-quarter timing of sales. In Q3, demand for digital detectors for non-destructive inspection increased across several of our industrial verticals, including battery inspection and oil and gas. However, demand for imaging products for security screening at ports and borders, as well as baggage screening at airports, continued to be soft. I'd like to take a few minutes to provide an update on China. As we have talked about in the past, China represents a significant growth opportunity for Verix. This has been mainly driven by strong demand for CT systems. Increased installations at fever clinics and a focus on making rural health systems more self-reliant are expanding the need for CTs in China. This growing installed base of CTs is expected to generate continued demand for replacement tubes. Our strategy in China of establishing relationships with local OEMs drives continued growth momentum. And as we have said recently, of the initial 12 CT projects that we have been working on with eight local OEMs, nine projects have been brought to market, and three are still in process. In addition to the continued adoption of new CT systems, we expect the previous generation of 16-slice CT systems to be upgraded to 64 and 128 CT systems. This upgrade cycle of the current installed base in China should add another layer to an already strong growth story. These system upgrades are expected to be driven by China's goal of building a more self-reliant rural healthcare system that can handle advanced diagnostic procedures, including cardiac applications. We expect our revenues from China to exceed $100 million by fiscal year end 2021, which would represent 25% to 30% year-over-year growth for the last two years. While digital detectors have been a significant part of our early growth story in China, year-to-date medical tubes represented over half of the revenues in China. We think this is key to the future growth story of our business in China. The majority of the installations of medical CT tubes is for new systems, which will contribute to future demand for replacement tubes. Outside the CT market, we see other avenues of potential growth in the region. As we have pointed out in the past, our Wuxi facility is capable of manufacturing several thousand detectors per year. The detectors manufactured in the Wuxi plant now span various modalities, including radiographic, dental, oncology, and fluoroscopy. This broad set of local offerings and strong industrial detector sales have enabled our detector sales in China to reach levels previously achieved in 2017 and 2018 prior to the onset of the trade war with China and associated tariffs. In addition, our local OEM relationships in China provide a platform to grow into other modalities. We are currently targeting into cardiology, dental, and radiation therapy. We are very excited about the opportunities that China represents and look forward to continuing to work with our OEM partners delivering on the expansion and improvement in healthcare delivery system for the region. Let me now give you a brief update on product development efforts. First, we recently launched the Lumen 4336W detector with IP68 rating which allows the detector to be immersed in liquids which can help with cleaning and disinfection. This detector is part of a new platform which offers other advanced capabilities as well as increased durability and ease of use for end users. With COVID continuing to be a problem globally, we believe these detectors will be well received by OEMs and healthcare providers. Second, on the Z platform front for dynamic digital detectors, our first new product is approaching formal product launch with two more following soon after. All three models are getting traction with OEMs and are covered by a few multi-year customer contracts. Third, in the area of nanotube technology, our joint venture has continued to make progress with product life testing with good results and is now working on customer prototypes. And lastly, during the quarter, we completed the acquisition of the outstanding minority stake in direct conversion, reflecting our continued belief in the potential for photon counting detector technology. Before I turn over the call to Sam, I just want to spend a minute talking about global supply chain issues that you are all aware of. During the second quarter, we highlighted supply chain constraints largely around freight and logistics. Supply chain challenges became more pronounced in the third quarter and is impacting the availability of some raw materials and semiconductors. We have been able to work through these challenges so far, but we see potential for supply chain constraints and shipping disruptions in Q4 and beyond. Our output may become challenged by these supply chain constraints, and we are working very closely with our current and alternate suppliers to mitigate potential impacts. With that, let me hand over the call to Sam.
Chris Belfiore
Thanks, Sonny, and hello, everyone. As a reminder, unless otherwise indicated, I'll provide sequential comparison of our results for the third quarter of fiscal year 2021 with those of our second quarter of fiscal 21. VARICS continued to deliver strong results in the quarter, and we saw solid demand across all modalities. For the quarter, Revenue was above the guidance midpoint and non-GAAP EPS was above the top end of the guidance range. Third quarter revenues were $211 million, an increase of 4% from the second quarter. Medical revenues were $167 million and industrial revenues were $44 million. For both RAREX in total and the medical segment, this is the highest revenue level in three years. This translated to 9% medical and 21% overall industrial sales. Sequentially medical sales grew 7% while industrial sales declined 6%. The decline in industrial sales was due to the timing of shipments, which is more of a quarter to quarter aberration. Revenue levels in all three regions remained strong. America's was down 7% sequentially. while EMEA grew 13% and APAC grew 6%. Let me now cover our results on a GAAP basis. Third quarter gross margin was 35% and up over 300 basis points sequentially from the previous quarter. Operating income increased $10 million compared to the second quarter and operating margin increased 400 basis points sequentially to 12%. Net earnings increased $9 million compared to the previous quarter, and earnings per diluted share were 29 cents compared to 8 cents in the second quarter. Moving on to non-GAAP results for the quarter. Gross margin was 36 percent, a sequential improvement of 150 basis points from the second quarter driven by higher sales volume, and improved productivity in manufacturing and service areas, partially offset by unfavorable product mix. Our gross margin has improved sequentially from 28% in the last quarter of fiscal year 2020 to 34% in Q1, 35% in Q2, and now to 36% in Q3. As this year comes to an end, we are achieving the gross margin target that we set earlier in the year. This performance over the last four quarters has been possible due to a continued increase in sales volume, timely completion of cost reduction goals, favorable product mix, and through our initiatives to improve efficiencies in our manufacturing and servicing activities. Despite the ongoing freight and supply chain-related challenges, we are very pleased with our gross margin performance. R&D spending in the third quarter was $19 million, or 9% of revenues, which is in the middle of the 8% to 10% range that we target for R&D. R&D was 42% of operating expenses in Q3, as compared to 41% in Q2, reflecting our continued spending prioritization towards innovation and new product development. SG&A was approximately $27 million in Q3, slightly higher than the prior quarter, but sequentially down 30 basis points as a percentage of sales. Operating expenses were $46 million and sequentially up approximately $1 million due to increase in R&D. We continued to keep operating expenses in control while successfully meeting increased customer demand, helping improve the quarterly profitability. Overall, our strategy to deliver higher earnings through improved operating leverage is on track and working very well. Operating earnings increased to $30 million or 14% of revenue as compared to $26 million or 13% of revenue in the previous quarter. Tax accounts in the third quarter was $6 million as compared to less than $1 million in the previous quarter. Recall, during Q2, two one-time favorable items in taxes drove a $2 million benefit and resulted in an unusually low tax expense for Q2. Net earnings increased to $16 million or 40 cents per diluted share compared to $14 million or 35 cents per diluted share in Q2. Despite a higher tax rate in Q3 of 26%, we were able to grow EPS by 5 cents compared to the second quarter. Please note that due to our convertible notes-related bond hedge and recently achieved GAAP income profitability and the associated trading range of our shares, there is a difference between diluted shares for GAAP and non-GAAP purposes. We have provided a reconciliation between the two at the end of our earnings press release. Now turning to the balance sheet. Accounts receivables increased by $19 million, partially due to higher sales. As a result, DSO increased by six days to 64 days. Inventory declined $5 million, and days of inventory declined to 161 days. Accounts payables increased by $14 million, mainly due to increase in raw material procurements to support higher demand. As a result, days payable increased to 44 days. Now moving to debt and cash flow information. Cash flow from operations improved to $22 million. We ended the quarter with cash of $128 million on the balance sheet, an increase of $17 million in the quarter. Gross debt outstanding at the end of the third quarter was $512 million, and debt net of cash came down to $384 million, reflecting our priority to continue to delever on a net debt basis. As we announced in early July, our cash generation enabled us to pay down a portion of our debt. On July 15th, we redeemed $30 million of our $300 million senior secured notes. Due to debt reduction on a go-forward basis, interest expense will be lower by approximately $2.4 million on an annualized basis. Adjusted EBITDA was $39 million in the third quarter, a solid improvement from $33 million in the prior quarter. I'm pleased to note that if you were to annualize over the last six months of performance, the net debt leverage ratio at the end of Q3 would be below three times. In summary, our previously stated financial strategy of improving capital leverage and operating leverage is working very well. I want to take a moment to thank our RADx colleagues worldwide for their tremendous efforts in achieving these results. With that, let's look at our expectations for the fourth quarter. Revenues are expected between $205 and $225 million. and non-GAAP earnings per diluted share are expected between $0.25 and $0.40. Our expectations are based on non-GAAP gross margin in a range of 35% to 36% and non-GAAP operating expenses in a range of $46 to $47 million. And with that, we will now open the call for your questions.

Anthony Petrone
Thanks, and congratulations on a strong quarter. I hope everyone is doing well. Maybe, Sunny and Sam, we can start with just sort of the dynamic between the underlying demand, and maybe that's mostly on the CT side in China, and just your comments on the supply chain. It just seems that while on the one hand we do have an elevated level of demand that's perhaps linked to some level of backlog recapture out of the pandemic, there's still some uncertainties on the supply chain. So maybe a little bit more details on underlying CT tube and component demand and where you see the specific bottlenecks in the supply chain and how you think it sort of trends over the next 12 months. Thanks.
Howard Goldman
Hey, Anthony. This is Sonny. So we're in a strong demand environment. And at this point, we feel good about as we head into the fourth quarter and looking into next year, we feel good about the demand side. And the issues with supply chain are fairly similar to what you would have been hearing from other companies in that There's two categories of supply chain issues. One where just there is a shortage of commodities. And we have been dealing with it for quite some time. I mean, you know, you find sometimes coppers where there's a shortage of copper or a shortage of aluminum and castings. And it's a daily discussion with suppliers and making sure we have a good handle on their delivery dates and what they're doing, that they understand our demand side and we're doing all the right things. placing appropriate orders and lead times, et cetera. And that's what we're battling. And we've been doing that. But lately, semiconductor side has also become, you know, has become an issue. So the way I would summarize this is there are supply chain issues that are broader than what we faced maybe a couple of quarters ago with more commodities, more materials, and more suppliers that are every now and then becoming delinquent and were, you know, delimiting their shipments. But going into the fourth quarter, we have accounted for that, and we have tried to de-risk that. So we have visibility to our supplies, you know, as we look forward to at least the next quarter. But as we look further out, we just sense that the risks are, you know, the risks are broader than they were a quarter ago. We're managing our way through it, doing all the things that we can. We're lining up alternate suppliers, qualifying alternate sources, Um, but I just wanted to highlight that we're at this point, given the strength of the demand side, we're not demand constrained right now in the near term. And, uh, we will continue to work the supply chain side.
Anthony Petrone
That's helpful. And just a couple of follow-ups for Sam, if we can get it in. Adjusted gross margin, 36%, even with the supply chain issues, um, you know, having an impact in the quarter. How much of that benefit was just sales volume related versus cost savings on Santa Clara? And then the last one for me would be on the R&D side. 9% of the higher sales base was ahead of the recent trend. I'm just wondering, is that linked to additional tenders or was it a pull forward on other R&D initiatives? Thanks again.
Chris Belfiore
Yeah, thanks, Anthony. Taking your first question related to gross margin, yes, definitely gross margin is benefiting from higher sales volume, and it has continued to benefit over the last few quarters as we are increasing sales every quarter. So that is definitely beneficial. In terms of cost reduction and Santa Clara update, you know, we have – completed all of that migration, all the migration of manufacturing from Santa Clara to Salt Lake. That is pretty much, that is fully done at this point. And we are benefiting, say, around $14, $15 million on an annualized basis. So that, say, comes to around $3.5 million a quarter. So say 150 basis points. So that we are benefiting and that is fully flowing through the P&L at this time. I would say that we had previously committed 100 basis point gross margin improvement towards the end of this fiscal year. So around Q4 for FY21 related to streamlining our manufacturing and servicing activities. And I would say that we are pleased to say that, you know, we have achieved that a bit sooner. We have achieved that in Q3. So that was a very big factor in terms of productivity improvements a bit sooner than initial plan or initial commit. And so that is benefiting gross margin. So that was about 100 basis points. And the things that are hurting gross margin or what I would call headwinds to the gross margin. It's clearly freight-related items. Freight is continuing to run high. As you know, there is uncertainty related to timeliness of ocean-related freight. And until all of that gets sorted out, those delays and those uncertainties, we are using a bit too much of what I call air freight, and that is definitely more expensive. So currently, freight is a headwind of about 20 to 30 basis points ongoing. But overall, they're positives and negatives, but overall, we are very pleased with the gross margin performance, and those are the percent takes that I talked about. Now, moving on to the next question in terms of the R&D as a percentage of Yeah, so we target 8% to 10%. We came in right around the middle of that, $9 million. You know, a lot of our R&D is driven by materials-related spending and when the engineers order, when that is delivered, et cetera. So there can be a little bit of, you know, fluctuation from quarter to quarter. But overall, we are investing in R&D. We are investing in delivering innovative products. There is a lot of need by R&D groups for more spending and actually accelerating the pipeline, et cetera. So I would say right now we will be fully funding R&D, and I don't think we are close to 10% of sales or anything like that, at least at this time. But we will guide you as we come closer to it. So right now I think 9% I feel good about. and we feel good about releasing new products and all the work that is going on with our teams. Thank you.
Operator
Your next question, Larry Solo with CJS Security.
Larry Solo
Good afternoon. Thanks for taking the questions, Howard. Best of luck to you, and Chris, welcome aboard. Just to follow up on Anthony's questions just on the supply chain constraints and whatnot, just in terms of guidance, you mentioned that 2.3, the mix was a little bit of a headwind or a little bit down. Just trying to parse out with your guidance for Q4, just at the high level, it's a It seems like you need to get to the high level of sales to kind of match the Q3 EPS. Is it more or less just the supply chain concerns and freight concerns, or is there any other issues just as we look sequentially from Q3 to Q4 that would create that?
Chris Belfiore
Yeah, so let me take this question, Sam, here. So, yeah, in terms of Q3, there was a little bit of an unfavorable mix, and that is really driven by less of an industrial sales as compared to the prior quarter. So that is what that refers to. So, as you know, industrial is a higher margin segment for us. So that is the unfavorable mix there. Okay. And then in terms of gross margin, you know, I have shared with you that I shared with you maybe two or three, maybe even a year ago, that our gross margins, when we get back to pre-COVID levels in terms of revenue, say 205, 210 or something like that, in that range, we are expecting gross margin 35 percentage plus minus one percentage points. Because, you know, we have different customer concentration, different product concentration, and a number of other things. And things can move from one quarter to another. You know, customers can push out shipments, you know. So we are still within that range. In Q3, we came out at around 36. And we, instead of guiding 35 plus minus one, we are guiding 35 to 36. So compared to what we had set expectations on, I think we're a little bit on the higher side there. And there isn't really nothing else beyond that at this time, Larry.
Larry Solo
Okay. All right. Fair enough. Just maybe a couple of questions in terms of China. You guys are obviously meeting or exceeding expectations that you've spoken about for years. Just trying to figure out, is there any sort of clarity, obviously, in terms of without getting into specifics, you know, you're doing a hundred. this year something more than 50 percent of that is from tubes um in terms of market share gains or or or not is i think you know and the players who are sort of serving the local oems is it just barracks and phillips can you give us any more clarity or you know other g siemens in there and the mix between you guys and phillips i don't know if you want to speak to that but you know, are they enjoying these same kind of numbers that you guys are? You may not have that great visibility or not, but any color, that would be great.
Howard Goldman
So Larry, you can frame it, I mean, one way to frame it would be the local OEMs are gaining share in CTs in China, in aggregate, right? If you take all the local OEMs combined, where they were a few years ago versus where they are today, vis-a-vis the local OEMs versus global OEMs, the local OEMs have gained share. We have a very large share of those local OEMs' consumption of tubes. So from our perspective, we're gaining share in tubes in a very nice way in China, and I feel good about that. So that's on a very good path, good trend, and these are all going into new sockets, so the market share position ought to keep growing, and we're bullish about that. On the detector side, I mentioned that. I'm happy to say that our detectors business has come back to the pre-trade war levels. Remember a couple of years ago when the trade war hit, we There were tariffs on both sides, and we were hit by those, and we pulled back in some areas because we just couldn't compete with extra costs. Since then, our actions have allowed us to increase. But that has been broad waste. It hasn't been in any one particular modality. Radiographic continues to be challenged with pricing, as we've talked about, particularly in the China markets. low end. But then there's dental, there's oncology, there's fluoroscopy. And so our strength and growth in detectors in China has been broad-based. Now, in terms of how we're doing versus overall market share, I'd say we're keeping up with the market growth rates, you know, better. But at this point, I'm not at a point to call out how we're doing versus others specifically. I'll just say that I'm really happy with the progress we've made with detectors and And particularly, we've also seen a growth in industrial detectors in China.
Larry Solo
Is there any way to tell the other global OEMs outside of China? They're still providing, you know, China has this whole, right, initiative to have local homegrown equipment. But GE and Siemens are not even mentioning it. Are there other global OEMs still providing new equipment to the market, or is it mostly, you know, you know, yeah?
Howard Goldman
Absolutely. The global OEMs, the established global OEMs are still selling in China and they're still selling their CT systems and other modalities. Our revenues in China come mostly from the local players there, but also we also get our share of China sales through some of these global OEMs. But yeah, they're there. They're still a significant player in that market.
Larry Solo
Okay. Last question, maybe, Sonny, for you while you still got the platform here. I remember I look back, I think it was early 18, you guys, when you got the reduced tax outlook and you took some of that savings and you reinvested into business and you took sort of an investment into multiple price points on the CT market. and CT machines in China and multiple different new detectors. And you certainly, in the last couple of calls, been calling out, certainly on a qualitative basis, a lot of newer products coming out. And I think if I look back three years ago, what you had spoken about, we should see an acceleration in revenue as we look out sort of three years from now, some of these new products sort of start maturing from prototype and get into commercialization. I realize with COVID and some exact science, but you still kind of feel that over the next couple of years, we should see this acceleration of hopefully revenue growth, but certainly of new product contributions.
Howard Goldman
Yeah, so we, if you recall, we took some of the benefits from reduced tax rates and said we would invest in R&D. So we put in some additional money to R&D to accelerate development of some of the new platforms. And what you're seeing us talk about currently with our new detector platform, the Lumen platform, the Z platform, the work we're doing with photon counting, there have been a number, we accelerated some of that work. I mean, those products would have been otherwise longer to bring to market. So we are expecting future growth out of those products. And I think we pulled in the launch of those products by making those earlier investments. There were also investments that went into supply chain qualification validation to set up our presence in China. And you're seeing Some of that play out in the form of our growth in China. The China CT growth is across multiple tiers, the 16-slice, mid-tier, high-end. And so we invested heavily in the segments that we thought would play out the best in China. I'm happy to say that our assessments and the feedback and input that we got from our local OEMs has served us well, and we're hitting the sweet spot of the markets. It was going to be 16 slice for mass adoption, and that's how it's been. There's been tremendous growth there. And going forward, as I said, we are expecting, in addition to ongoing new socket sales and penetration of CT, there's going to be, and it's already begun, a wave of, we'll see the early 16 slice CT systems get replaced by 64, 128 slice CTs, the more feature-rich ones. And so all of that, I'd say, Larry, has been enabled by us being at the right place at the right time with the products. Otherwise, we would have probably had a more muted success in China. Fair enough.
Larry Solo
Great. Thanks for the call. I appreciate it.
Sunny Sanyal
She lost her connection.
Howard Goldman
Yeah. Hey, our operator lost her connection. She's getting back on, so just hang in there. If there's additional questions, please hold for a second.
Operator
Ladies and gentlemen, we do apologize for those technical difficulties. I'll move on to our next question, which is coming from the line of Siraj Khalia with Oppenheimer. Please proceed with your question.
Sam
Hi, Siraj.
Siraj
Good afternoon, Sunny. Sam, hope you're well. Congrats on the quarter.
Sam
Thank you. Thank you.
Siraj
Hey, so, Sonny, a lot of questions have been asked. You know, maybe if I can just phrase it differently. Sonny, the demand, obviously, there's the demand and the supply issues that you talked about. On the demand side, is the pickup, I mean, it just seems like Varex is moving into the next gear. Is the demand pickup more sort of catch-up in nature? Or are you seeing any structural changes that would be more durable, so to speak? And I'm not talking about two quarters. I'm talking more multiple, multiple quarters.
Howard Goldman
Yeah, so it's a function of three different vectors. There's a little bit of a catch-up that there was in modalities where there was some pause. So, for example, there was a quarter where we had lower sales in oncology, and there was some catch-up, and they've caught up. But CT demand continues to be strong, and it's not just a catch-up. There was no catch-up in CT. It is just an expansion of healthcare services, and it has been global. People are buying CTs at a demand rate that is higher than that was expected, and based on the forward-looking views that we're getting from our customers, you know, we As you know, our customers give us their annual plan, give us six months of estimates. We continue to see strong demand for CT. And for an extent of their time, this is not us trying to catch up on the backlog or not being able to deliver and hence a pileup. In other modalities, like dental, The recovery has been at different levels and different velocities at different points in time. So dental has been just ongoing, still catching up in some markets. And so I could go – I mean, so every modality has its story, right? Rad has had a tremendous – uptake during covet there was a gap there there's a little bit of slowing down and then it's picking back up so it's hard to hard to pinpoint one thing down but as we look at it in aggregate we see that the demand side is strong and our expectation is that our customers who have taken a lot of orders during this time and they carry backlog that they are also going to continue to have to deliver on what they've taken over the next six to nine months. So as we look forward, we continue to feel strong about, feel good about the demand side. And then lastly, there was the technology side of it. We've launched some new products. And anytime you launch a new product, you get some, you see an uptick in demand for some of those products. And we expect that will continue into next year as well.
Chris Belfiore
So Roger, I would also like to add here is that if you remember six, nine, six months ago or so, we added that a response to the pandemic might be that countries and communities would be spending on healthcare infrastructure and imaging, and hence us would benefit through that as a result of that. So we feel, um, it's not just one country situation. It's, it's broad based. It's broad based across region modalities. and seems to have strong legs to it. There is no one country that can say that strong, etc. So I think the strength in China is somewhat new for us. The strength broad-based, which is driven by, say, healthcare response, that is aiding, and then obviously the new products that Sunny kind of just said. So, you know, add it all together, and that makes makes the difference. That's true.

And if you take a look at the industrial side, a lot of the demand that we've seen has come from market expansion, I mean, expanded activity in the market, like electronics inspection, battery inspection, you know, the semiconductor inspections, that has driven also additional volumes. And realize that we haven't yet caught up on the security and inspection side, and airports has still been soft. So there's some more headroom there. So as we look at the overall demand profile, we feel good that there's some, there's real momentum there and market-driven momentum.
Siraj
Got it. Sonny, does the Delta variant concern you on the industrial side of the equation?
Howard Goldman
You know, not particularly. And the reason for that is, if at all, travel is an area that gets impacted first, as you know. And for us, the security-related side of our business has been slow. And we're still waiting for any significant recovery there. So if at all, it'll be status quo for us on the cargo and security side. On the industrial side, where the demand has been strong, has increased, has been strong despite COVID. After that initial blip, initially when COVID hit, there was just a shock to the whole system and all the factories sort of stopped and people were frozen. And we saw a couple of quarters of industrial, pretty sharp slowdown in industrial. Since then, the recovery has been almost despite COVID. So I don't think that we will experience the same, you know, it'd be hard to pin it down, but You know, the demand side of industrial, particularly with semiconductor inspections, battery inspections, electric inspection, that doesn't seem to be COVID-related. Oil and gas did slow down, but that was because of oil prices more so than COVID.

Got it. Sunny and Sam, final two. I'll just put both of them together. Sunny at RSNA. Are we going to get an update on the core cathode status? And Sam, maybe this has already been asked. Please forgive me if this is redundant. The components of the 205 to 225 guide, how do you think through the medical and the industrial segments? Gentlemen, thank you for taking my questions and congrats once again.
Howard Goldman
Let me answer the first one. So on the cold cathode technologies, what we are, our status is that we are continuing on with the foundational technology development. And now, you know, we are past the validation emitters and strength of emitters. We're now into tube development and more of the validation-like testing there. And we are in the mode, next phase of our new product introduction mode, where we start building products, sample, I mean, prototypes for our customers. We're in that mode. Our city is only, you know, two months, a couple of months away, so you're not going to hear anything significantly different. You'll hear more of the same, that we're working on customer prototypes, getting customers engaged, and looking at developing agreements with customers.
Chris Belfiore
And, Suraj, coming back to your question in terms of the industrial and medical breakdown of the guide, generally, as you know, industrial is 21% or somewhere around that. of overall revenues for us. And so I would say that is still our expectation, but stuff moves around here and there from quarter to quarter. So I would say 21% of industrial plus minus 1%, that would be the normal expectation. So the guide and the growth is not necessarily pegged to medical only or industrial only. Both of them are growing for us and it may not exactly look that way once you go from one quarter to another. But as you look over multiple quarters, you would see that both are growing and you would expect both to grow. And demand is pretty good on both sides. It will just come down to what we can supply through the factory and where it ends up. But demand-wise, we feel good about both of the segments.

Once again, if you would like to ask a question, please press star 1 on your telephone keypad. Your next question comes from Jim Sidoti with Sidoti & Company. Please go ahead.
Jim Sidoti
Hi. Good afternoon. Good afternoon. I'm going to try and ask the question. I think it's been asked a couple times. I'm going to ask it a little bit different. You just had two strong quarters over that $200 million mark. You've got him for a third one over that $200 million mark. So the fourth quarter, is there anything such as supply constraints or any other kind of headwind out there that you're concerned about that would cause you to dip below that $200 million per quarter mark over the next year or so? Is there anything like that that you're aware of?
Chris Belfiore
Let me try to address that, Jim. So when it comes to Q4, as you know, we only guide to the border, so we are guiding only Q4 right now. And in terms of Q4, the demand and, of course, on the supply side, we feel good about based on the visibility that we have. So that is how we have balanced our guidance for Q4. But as you know, there can be a 100-year event or something can happen, so we would never say that It is 100% assured or anything like that. There can be a chance that something happens which is completely unforeseen to us and we dip below $200 million. That can happen to any business and we would never say that. But overall, in terms of balancing the guidance, balancing the numbers, that's how we are providing the guidance for Q4. Beyond Q4, the visibility comes less from supply chain and all of those issues as well as The farther out we go, the visibility is lower. Currently, we are operating in a supply-constrained environment as opposed to a demand-constrained environment. And we feel good about our situation and position of the $200 million watermark that you kind of highlighted. But there isn't anything that tells us that, hey, there is a significant this thing or that thing coming. But That doesn't mean that it may not happen. It may happen, which may be unknown to us. And as and when it happens, we'll share with you. But as far as where we sit as of today, we feel good about our guidance and good about our business going forward beyond there. I guess that's as much as I can add. I don't know, Sonny, if you'd like to add something else.
Howard Goldman
No, I think nothing more to add there, Jim. We're good. demand trajectory is in the right direction. So let me just leave it at that.
Larry Solo
Okay.
Jim Sidoti
All right. And then I want to detail on the balance sheet. You can't see most picked up in the quarters. Is that the timing of shipment? Can you just add a little color to that?
Chris Belfiore
Yeah, I can add a little bit more color to that, Jim. Good question. Thank you. Yes. So Obviously, the sales is growing, so when sales grows, AR picks up. That's just normal working capital that's there. There is one large customer of ours that decided for their own balance sheet dresser purposes to pay us a significant amount of cash just the one week after the quarter ended. So our AR was a little bit higher in terms of DSO than I would have liked, but it's just stuff that happens. Beyond that, there's nothing else to that.
Jim Sidoti
All right. That's it for me. Thank you. Thank you.
