Greetings. Welcome to the Varex second quarter fiscal year 2022 earnings call. At this time, all participants are in a listen-only mode. A question and answer session will follow the formal presentation. If anyone should require operator assistance during the conference, please press star zero on your telephone keypad. Please note this conference is being recorded. I will now turn the conference over to your host, Christopher Belfiore, Director of Investor Relations. You may begin.
Good afternoon and welcome to Varex Imaging Corporation's earnings conference call for the second quarter of fiscal year 2022. With me today are Sunny Sanyal, our President and CEO, and Sam Maheshwari, our CFO. Please note that the live webcast of this conference call includes a supplemental slide presentation that can be accessed at Varex's website at vareximaging.com/news. The webcast and supplemental slide presentation will be archived on Varex's website. To simplify our discussion, unless otherwise stated, all references to the quarter are for the second quarter of fiscal year 2022. In addition, unless otherwise stated, quarterly comparisons are made sequentially from the second quarter of fiscal year 2022 to the first quarter of fiscal year 2022, rather than to the same quarter of the prior year.
Finally, all references to the year are to the fiscal year and not calendar year, unless otherwise stated. Please be advised that during this call we will be making forward-looking statements, which are predictions or 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 Sunny.
Thank you, Chris, and good afternoon, everyone. We continued to see robust demand for our products in the second quarter of fiscal 2022 and achieved sales of $215 million despite ongoing supply chain constraints. The current operating environment remains challenging with persistence of tight constraints, inflationary cost pressure, and continued COVID-related shutdowns outside the U.S. While we continue to work to mitigate these headwinds, they impacted our performance in the second quarter, and we expect this to continue in the third quarter. Despite these headwinds, we remain focused on delivering on our backlog while investing in innovation and being the partner of choice for our customers. Turning to the results, revenue in the second quarter increased 8% sequentially and 6% year-over-year. Revenue in both medical and industrial segment increased sequentially.
Non-GAAP gross margin in the quarter was 34%, in line with our expectations as price actions helped offset some of the cost increases. Adjusted EBITDA was $38 million and non-GAAP EPS was $0.37. Our cash position remains strong at $115 million at the end of the quarter. Balance was down $43 million sequentially, driven by redemption of $27 million of our senior secured notes as well as working capital investments. Now, based on a qualitative assessment, let me provide some high-level insights into the demand environment for our different modalities and applications during the quarter. Medical segment revenues increased 10% sequentially and 9% year-over-year. We continued to see robust demand globally for CT tubes. Demand was also strong in our other medical modalities, including fluoroscopy, oncology, radiography, dental, and mammography.
In addition, all modalities posted improved revenues compared to the prior quarter and a year ago. Revenues in our industrial segment increased 3% sequentially and decreased 6% year-over-year compared to a very strong quarter in industrial last year. We continued to see strong demand for products for nondestructive inspection across several of our industrial verticals, including electronics inspection and aerospace applications. Similar to last quarter, we are experiencing improved demand for high energy sources and tubes for security screening. In previous quarters, we had mentioned that we had expected to see future demand as tender activity picked up. In the second quarter, we were pleased to see some of this activity translate into orders for us. In addition, we believe strong backlog at our customers bodes well for future growth in the security business.
Last quarter, we provided details on some of our new products in the medical segment. We continue to see good traction with our customers and their response to our new products. In our tubes business, our high-performance X-ray tubes for cardiovascular applications continue to see good initial customer interest. One customer is getting close to a system launch. Several others are evaluating integration and design options, and we continue to get positive reactions from additional OEMs. Our joint venture in Germany continues to make steady progress with nanotube technologies. As we noted in the first quarter, we signed a prototype development agreement with a medical customer, and we shipped the first multi-meter prototype to an industrial customer. We continue to work closely with this industrial customer as they work on integrating the prototype into their system and also shipped additional prototypes to the customer during the quarter.
In detectors, our photon counting technology continues to make progress and is currently being utilized or evaluated in a number of medical modalities, including dental, radiography, and mammography. Due to its high frame rate imaging ability, we continue to see photon counting adoption in inline industrial inspection systems with automated detection. We are seeing increased orders from customers in Japan, Europe, and the U.S. for food inspection systems focused on foreign particle detection as well as analysis of food content. Towards the end of this year, we expect to see additional customers launch new systems utilizing our photon counting detectors in food inspection and in battery inspection. We have had multiple design wins with our Z Platform dynamic detectors, now called Azure, in mobile C-arm and dental applications. We expect production of these systems and our product shipments to start ramping up in the second half of 2022.
In addition, more customers are evaluating our prototypes with positive feedback. Separately, we're seeing good progress with the launch of our Lumen Series RAD detectors. We are excited to see that the Lumen Series is performing well and that several of our existing customers are migrating to this product. We expect to see more competitive wins with the Lumen Series. As we have talked about for several quarters, we continue to see robust demand across the business. Strong order momentum continues, adding to an already solid backlog. Our customers' confidence in our ability to work through the current backlog through their issuance of new orders supports our expectations for a continued strong demand environment. Despite current COVID-related shutdowns in China, demand in China remains strong, especially for our CT tubes.
Our investment in manufacturing capacity in Wuxi has enabled us to meet our Chinese OEMs' needs for local service and supply, which gives them a competitive advantage. We recently attended a medical imaging exhibition that is part of Japan Radiology Congress. We were happy to see that the conference was well-attended by medical imaging OEMs, and we were able to connect live with many of our customers. Japan is a hub for many global medical and industrial imaging OEMs, and our discussion with them confirmed our perspective on the continued strength in CT and imaging systems for surgery. We also saw signs of demand recovery in the high-end cardiovascular systems, which had slowed down during the past two years due to COVID.
There was also a growing interest and acknowledgement of the potential for photon counting technologies in medical imaging, confirming that our investments in nanotube technologies are on the right path. As you are all aware, supply chain challenges continue to be a pressure point for Varex and many other companies globally. We continue to operate in a hand-to-mouth environment for certain components, like semiconductors and related electronics. This situation is further exacerbated by erratic vendor performance across the supply chain, which we expect will continue into the near future. Let me outline the measures that we are taking to respond to these challenges. First, we have increased inventory levels of key parts and materials. Second, we are redirecting our R&D efforts to redesign certain products and qualify new suppliers. Third, we are sourcing semiconductors from the spot market by paying higher prices.
Fourth, we're prepaying certain vendors to improve the likelihood that we receive the material when we need it. Lastly, we moved shipments from ocean to air freight and are using expedited shipping. These measures helped mitigate some of the supply chain constraints in the second quarter, but at the expense of profitability. In summary, as we look forward toward the second half of the fiscal year, we expect supply chain volatility to continue. We're pleased to see robust demand for our products. Pending successful completion of supply chain diversification efforts, which are already underway, we expect fiscal 2022 to be another growth year for Varex. With that, let me hand over the call to Sam.
Thanks, Sunny, and hello, everyone. As a reminder, unless otherwise indicated, I'll provide sequential comparison of our results for the second quarter of fiscal 2022 with those of our first quarter of fiscal 2022. Demand remained robust during the quarter, and we were able to mitigate some of the supply chain constraints in the last few weeks of the second quarter. This allowed us to post revenues of $215 million, which was $10 million above the midpoint of our expectations. That said, rising costs of raw material and logistics pressured gross margin, offset by volumes being higher than expectations and our pricing initiatives. Non-GAAP EPS was near the top of our guidance at $0.37, which benefited from a credit to SG&A expense.
Second quarter revenues increased 8% from the first quarter, helped by improved production towards the end of the quarter. Medical revenues were $170 million, and industrial revenues were $44 million. Sequentially, medical sales increased 10%, and industrial sales increased 3%. Medical revenues were 79%, and industrial revenues were 21% of the overall revenues for the quarter. Looking at revenue by region, Americas increased 13% sequentially, EMEA increased 3%, and APAC increased 8%. Overall, China was 15% of the revenue in the quarter. Let me now cover our results on a GAAP basis. Second quarter gross margin was 33% in line with the previous quarter. Operating expenses were $44 million, down $7 million, and operating income was $27 million, up $13 million sequentially.
This resulted in net earnings of $8 million and GAAP EPS of $0.18 on fully diluted 42 million shares. Moving on to non-GAAP results for the quarter. Gross margin was 34% in line with our expectations and similar to last quarter. Price improvement offset by higher costs helped us to maintain our gross margin sequentially. Freight expenses impacted gross margin by about 30 basis points compared to the first quarter and by 100 basis points compared to the year-ago quarter. Compared to pre-COVID levels, freight expenses are impacting gross margin by roughly 150 basis points as of now. Like previous quarters, we continued to qualify various alternate suppliers and as a result, R&D resources were diverted towards mitigating supply chain issues. These activities impacted gross margin for the quarter by about 30 basis points.
As we have stated previously, in late October 2021, we communicated broad-based price increases of mid-single-digit percentage or higher. Since many customers are on an annual contract, we expect to realize price increases gradually throughout fiscal 2022. At this stage, we are seeing traction with this initiative, and we continue to work with the remaining customers as their contracts come up for renewal. I want to reiterate that price improvement initiatives were launched to offset cost inflation and not an initiative to improve profitability. R&D spending in the second quarter was $19 million, up $1 million from the prior quarter. It was 9% of revenues within our 8%-10% target range. SG&A was approximately $22 million, $4 million lower than the prior quarter. The decrease was related to a credit associated with our incentive plans.
As a result, SG&A was 10% of revenues, demonstrating the operating leverage in the P&L. Operating expenses were $41 million or 19% of revenue, down $3 million from the prior quarter, driven mainly by lower SG&A. Operating earnings were $32 million, up $4 million sequentially. Operating margin was 15% of revenue in the quarter compared to 11% in the first quarter. Tax expense in the second quarter was $7 million or 31% of pre-tax income. Please note that we continue to target about 25% tax rate for the full year. Net earnings were $15 million or $0.37 per diluted share, compared to $10 million or $0.25 per diluted share in the first quarter. Average diluted shares in the quarter were 41 million on a non-GAAP basis.
We have provided a reconciliation between GAAP and non-GAAP shares at the end of our earnings press release. The appendix to our slides provides a table showing the effect of our bond hedge on the diluted share count for GAAP and non-GAAP purposes at different share prices. Separately, ASU 2020-06, which is related to the accounting for convertible instruments, will become effective for us from Q1 of fiscal year 2023 onwards. Now turning to the balance sheet. Accounts receivable increased by $27 million due to higher sales late in the quarter. Hence, DSO increased to 65 days. Inventory also increased $22 million as a result of our actions to stock larger quantities of parts and materials. This also included having to pay higher prices for semiconductors and prepaying certain vendors to improve the likelihood of receiving the material timely.
As a result, days of inventory increased to 170 days. Accounts payable increased by $7 million, and days payable was 50 days. Now moving to debt and cash flow information. Cash flow from operations was a reduction of $8 million in the second quarter, and we ended the quarter with cash of $115 million on the balance sheet, a decrease of $43 million from the prior quarter. The decrease in cash was a result of the redemption of $27 million in principal amount of our senior secured notes, as well as an increase in inventory and accounts receivables. Gross debt outstanding at the end of the quarter was $452 million, and debt net of cash was $337 million. Adjusted EBITDA was $38 million, and adjusted EBITDA margin was 18% of sales.
The combination of profitability and our solid cash position helped keep our net debt leverage ratio to 2.3 times at quarter end. Before providing guidance, I wanted to take a step back and discuss broader revenue dynamics in connection with Sunny's comments earlier. Our Q2 revenue came in above the midpoint of our expectations. This was mainly due to receiving certain raw materials to complete product assembly towards the end of the quarter. This dynamic was the exact opposite of what we experienced in Q1, but somewhat similar to what we experienced in the fourth quarter of fiscal 2021. It illustrates the significant volatility in the current supply chain environment, and in the face of strong demand, will continue to influence our sales performance in the near future.
However, we expect our supply chain diversification initiatives to progress further and reduce this volatility as we move past the third quarter. With that as a backdrop, here is our guidance for Q3. Revenues are expected between $190 million and $220 million, and non-GAAP earnings per diluted share are expected between $0.10 and $0.30. Our expectations are based on non-GAAP gross margin in a range of 32%-34%, non-GAAP operating expenses in a range of $45 million-$46 million, tax rate of about 25% for Q3 and fiscal 2022, non-GAAP diluted share count of about 41 million shares. With that, we will now open the call for your questions.
At this time, we'll be conducting a question and answer session. If you'd like to ask a question, please press star one on your telephone keypad. A confirmation tone will indicate your line is in the question queue. You may press star two if you'd like to remove your question from the queue. For participants using speaker equipment, it may be necessary to pick up your handset before pressing the star keys. One moment please while we poll for questions. Our first question is from Larry Solow with CJS Securities. Please proceed with your question.
Great. Thanks. It's CJS. Good afternoon, guys. Just on the realization of price increases, Sam, you mentioned sort of those price increases were put in obviously more on defense as opposed to offensive, just to sort of cover your costs. Just a couple questions there. You mentioned most of your, you know, these are annualized contracts. I assume they're kinda calendar 2022, so we're not even, you know, halfway through the year yet or less than that, obviously.
You perhaps you've done some of them, but hopefully you still have some, at least some, you know, wind at your back in terms of, you know, more price increase or benefit rolling through, but perhaps costs are even higher than you know when you first start putting these in. Do you come back to the drawing board and maybe put more in, or how do you look at that? Am I sort of my assumption that you still have a good amount to go, is that a fair statement?
Thanks, Larry. Yeah, sure. We communicated to our customers in October, and then we started working with them on price increases. That activity, like you rightly pointed out, began to kick in effectively from the January of this year. It is going on a rolling basis. We still have more activity ahead of us, and as the contracts come up for renewal, we are able to get those increases. In a way, as we mentioned that generally we have these on an annual basis, for the next round or phase two of it, the earliest it would be is October 2022, if we decide to send out the letters and monitor the cost at that time.
We will evaluate the situation at that time, but right now we are very much into our, call it, phase one, and we hope inflation subsides, but we don't really have a very good perspective right now. We will just monitor the situation and then act accordingly, but we are very much into the initial phase right now.
Right. Okay. Just in terms of impact or, you know, supply chain, just in terms of impact on revenue, not so much on the cost side, is the medical segment, and obviously it's a bigger piece of your business, but it looks like, you know, that segment has actually experienced better growth relative to sort of, you know, rebounding from COVID versus industrial. Is that more just 'cause their demand is better or is the industrial piece also maybe having, you know, disproportionate issues with supply?
I would characterize that they're both medical and industrial are kind of experiencing similar type of issues. If you would notice, you know.
Right.
Industrial for us is a 20% revenue type of segment that has been that way for many, many quarters, if not years, and that has continued on.
Right.
Here and there, Larry, for a given quarter, you might see a spot effect here or there. But other than that, from a static perspective, it's still 80-20 or 79-21 in terms of revenue split. That's continuing. You might see ±1% here or there in terms of proportional revenue for the overall company. They're both getting impacted similarly. Of course, in industrial business, we also have systems business particularly on the security side. That business, there's been a lot of tender activity in that business recently.
Mm.
When I say recently, I would say in the last six months, and Sunny mentioned that in his prepared remarks that we are seeing activity there. We are excited about that piece of the business finally beginning to, you know, come back from the COVID. On that business, there's been a bit of a delay from COVID to resurgence from COVID, whereas the other business has kind of picked up right after COVID.
Okay, great. Just last question. You know, Sunny gave us a little, you know, appreciate the update on the R&D side. Good traction sounds like on a bunch of new products. And it does sound like, maybe not an inflection point yet, but you know, a lot of these, you know, larger programs, it seems like you're at least, you know, reaching the prototype stage, and there's probably still some time to go before you have mass commercialization. But it does sound like we're, you know, getting at least closer on, you know, many of these programs. Is that, you know, fair to say?
Larry, the programs are moving forward. Our R&D program's moving forward. They've continued to be funded, and what's encouraging for us is that on the customer side, you know, there's also engagement and continued activity. You know, a couple years ago, some of that had slowed down, but we've seen now customers re-engaged in earnest.
Okay, great. I appreciate that. Thank you, guys.
Thanks, Larry.
Our next question is from Suraj Kalia with Oppenheimer. Please proceed with your question.
Good afternoon, Sunny, Sam, can you hear me all right?
Yes, we can.
Yes.
Perfect. Gentlemen, congrats on the quarter. Hey, Sunny, many calls going on at the same time, so please forgive me if you'll have already mentioned this. Your cold cathode, can you walk us through your regulatory approach and any specific OEM feedback that y'all have received, you know, that might require some tweaking?
Yes. Suraj, we provide the components to our OEMs who then incorporate these technologies into their systems. We don't file 510(k)s or seek regulatory approval per se, our OEM customers do. They have established processes and sometimes predicate devices that they'll use. That is not something that we actively pursue and not a real consideration in terms of how we launch this technology. In terms of feedback, you know, the OEMs are going through very similar process like they do with our other tubes and other tubes. Which is, when you have a novel technology, they go back and forth between what the technology can do and what they need. They go back and forth on that.
The feedback that we are getting from the OEMs have more to do with application-specific needs. The basic technology is working very well. The multi-emitter tubes are working well. They might say, well, we need X number of emitters instead of, you know. That's an ongoing process. It's very dynamic as our customers go through the design phase of their system. We're in that mode. With what we've done in medical and industrial, we're doing a combination of two things. You know, helping our customers with supporting them with their specific design needs, and secondly, continuing to market this to other OEMs. In with the eye on seeking out the applications that we think this technology is capable of serving.
Right. Sunny, forgive me, I should have been more specific about your end user regulatory approach. Would it be an array of devices in terms of different configs on the number of emitters, kVp, so on and so forth for, you know, across the board? Any update on the cycle testing, you know, where you all are? Or are we pretty much done for the most part, and it's commercial launch, let's say, X period down the line?
Look, we did a lot of the performance characterization early on, and then we talked to you guys about that in the last few quarters. We're past that point. We are satisfied with the basic performance, the capabilities, and we've got a handle on the performance brackets on what these tubes are capable of from a dose, energy, et cetera. That there's really no more new news to add there. What we are doing right now is purely focused on getting application mindshare and adoption. See, when you have a novel technology like this, it takes quite a bit of work together with the customers to get adoption. That's the phase we're in.
You know, once we get a few of these examples under our belt, we will be in a better place to then continue on with the demand generation side because we can give concrete examples.
Fair enough. Sam, one question, I'll throw it your way and hop back in queue. I know you briefly made some remarks about the lack of visibility in the current environment. Appreciate you know, your commentary. Sam, at what point would you care to give us a perspective on, you know, when inventory management, especially, you know, when LIFO comes into play, and that's where, because gross margins are a key component of your story, how are you all managing that so that LIFO really doesn't you know just, given everything going around with cost inflation. I'd love to get your perspective in terms of has there been any shift in your inventory management plans? Any additional color would be great. Gentlemen, thank you for taking my questions, and congrats.
Thank you, Suraj. Yeah, in terms of inventory management practices, you know, say six quarters or eight quarters ago, we were making our production and manufacturing processes more effective, and we were able to bring inventory down, and that was during the COVID phase. Since COVID, demand has significantly taken a turn on the positive side and followed by supply chain issues. At this time, you know, we are looking at stocking more raw material and parts.
From that perspective, on average, we are stocking more and our inventory has gone up, and it may go up a little bit more yet again. That's one thing that we are trying to do. Sunny outlined a number of initiatives in terms of making sure we have the raw materials to be able to meet the customer demand. We are taking all of those actions, as Sunny said, and I would simply add on top of that we are buying more, we are giving long lead purchase orders to our suppliers. Say if we were buying, giving a PO for three-four months in advance to a supplier, now we are doing double that.
In that way, we are providing a lot more visibility to our suppliers so that we are assured of getting the material. Those are some of the changes we have made. The factory as of now is running, I would say, inefficiently in the sense, and we have talked about it in the prior quarters with all of you, driven by supply chain start and stop nature, trying to scramble for material, and all of those things. Factories are inefficient. We are trying our best to manage through this situation, and we are also leveraging our balance sheet to ensure that we can meet the customer's demands.
Suraj, does that answer your question?
Yes. Thank you.
Thank you.
As a reminder, if you'd like to ask a question, please press star one on your telephone keypad. A confirmation tone will indicate your line is in the question queue. You may press star two if you'd like to remove your question from the queue. Our next question is from James Sidoti with Sidoti & Company. Please proceed with your question.
Good afternoon. Thanks for taking the questions. The first one is, can you talk about shipments on a, you know, for the three months of the quarter? Were they very heavily weighted towards the third month of the quarter because of the supply chain issues?
Hi, Jim, this is Sam. Yes, the shipments for the quarter were not linear, and they were tilted towards the third month of the quarter. As a result, it caused AR to be high on the balance sheet. Yeah. Last two, three weeks of the quarter, we were able to get the material, finish it up, finish the product, and we're able to ship it to our customers. Yes.
I assume there was a lot of overtime during that period, so that impacted the gross margin as well.
Yes. As I was just answering Suraj, yes, we do have overtime, under time, all of that goes on. We need many times to assemble and complete the product. All those aspects are covered when I say manufacturers are running inefficiently. Yes.
Okay. The credit for SG&A, can you just give us a little color on what that was about?
Yes. That credit was related to our incentive plans. In this quarter, we looked at, you know, where the demand is versus where we are able to ship. There is a gap, and we looked at that, and we looked at the performance of last year, this year, and we went ahead and adjusted for that and re-estimated it, and that's what caused the credit on the P&L.
Okay. We shouldn't expect that to continue in the second half of the year.
That is correct, Jim. It would be only for Q2. Outside of that credit, the operating expenses were in line with what we had guided you and also in line with what Q1 actuals were and also pretty much in line with what we are guiding towards Q3. The base outside of the credit, operating expenses are running around $45 million or $45-$46 million range.
Okay. You know, Sunny made a comment at the beginning, though, that despite the supply constraints, he still said you expected growth for the year. Is that top line growth or bottom line growth or both?
Jim, as of now, we are only guiding for Q3. We are hopeful of full year top line growth and full year bottom line growth.
All right. Thank you.
Thanks, Jim.
We have reached the end of the question and answer session. I will now turn the call over to Christopher Belfiore for closing remarks.
