Executive Vice President and Chief Financial Officer

Thank you. Good morning, and thank you for joining us. I'm Alan Edrick, Executive Vice President and CFO of OSI Systems, and I'm here today with A.J. Mehra, OSI's new President and CEO. Welcome to the OSI Systems Fiscal 25 Second Quarter Conference Call. We are pleased that you can join us as we review our financial and our operational results. Earlier today, we issued a press release announcing our Fiscal 25 Second Quarter financial results. Before we discuss these results, however, I would like to remind everyone that today's discussion will include forward-looking statements and the company wishes to take advantage of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995 with respect to such forward-looking statements. All forward-looking statements made on this call are based on currently available information, and the company undertakes no obligation to update any forward-looking statement based upon subsequent events or new information or otherwise. During today's call, we will refer to both GAAP and non-GAAP financial measures when describing the company's results. For further information regarding non-GAAP measures and comparable GAAP measures of the company's results and a quantitative reconciliation of those figures, please refer to today's earnings press release. I will begin with a high-level summary of our financial performance for the second quarter of fiscal 25 and then turn the call over to AJ for a discussion of our business and our operational performance. We will then finish with more detail regarding our financial results and a discussion of our updated outlook for fiscal year 2025. Our second quarter financial results were excellent with record Q2 revenues and operating income at the security division and solid performance by the OPTA division. We are excited by the momentum across our business and are confident that we are well positioned for the second half of the fiscal year. So let's start with a high level summary of our fiscal 25 Q2 results. First, revenues increased 12% year-over-year to a Q2 record of $420 million, with growth in each of the three divisions highlighted by the 16% year-over-year revenue increase in our security division. Second, the strong revenue growth led to record Q2 non-GAAP adjusted earnings per share of $2.42. Third, bookings were significant, and with a book-to-bill ratio of 1.2 in the quarter, We finished the quarter with a record backlog of more than 1.8 billion. Our strong backlog and robust pipeline of opportunities provide good visibility going forward. And fourth, we generated operating cash flow of 53 million in Q2, a 76 million jump over the same quarter in the last fiscal year. This performance was driven by strong profits and an improvement in working capital metrics. As you may know, We had mentioned in our previous call that our strong operating cash flow dynamics was expected to return in 25. Before diving more deeply into our financial results and discussing our updated outlook for the full fiscal year, I will turn the call over to AJ.

A.J. Mehra
President and CEO

I'm pleased to join this call as CEO for the first time after assuming the role on January 1st. It is gratifying to report another record-breaking second quarter for fiscal 2025, where we achieved revenues of $420 million, representing a 12% growth year-over-year and strong earnings. The quarterly performance was driven primarily by excellent execution in security and solid results from the Opt Electronics and Manufacturing Division. Our continued healthy backlog, as Alan pointed out, An expanding opportunity pipeline provides us confidence for robust growth in the second half and a fiscal year and positions us well for the future.

Let me discuss each division's performance, starting with security.

speaker
A.J. Mehra
President and CEO

The security division delivered Q2 revenues of $290 million, representing a 16% growth over Q2 in the prior year. Bookings were also excellent. as we achieved a book-to-bill ratio of approximately 1.2 for the quarter. During Q2, we continued to deliver on programs and numerous locations, including airports, ports, borders, and critical infrastructure. In addition, our turnkey projects are performing well in Albania, Puerto Rico, Guatemala, and Uruguay, which, as we mentioned before, commenced earlier last quarter. During the quarter, we received significant orders for both aviation and cargo products and announced a few of these wins shortly after the quarter ended. First, we announced a $27 million award to provide checkpoint and whole baggage inspection products for an international airport. The products to be provided include RTT-110, explosive detection systems for screening whole baggage, Orion 920CT checkpoint screening systems, which are integrated with our rapid scan tray return systems. In addition, we will supply our trace and other screening systems for air cargo. This award is the latest in a string of major international airport awards received in the past few quarters, which indicates promising growth for our aviation security product revenues going forward. Second, we announced an $81 million order from an international customer for EGLE M60 mobile high energy cargo and vehicle inspection systems for border security applications. Third, we announced a $32 million award from an international customer for M60s, including service and support for port and border security applications. Expanding our install base among aviation and border security customers not only broadens our hardware install base, but also significantly boosts our potential for future recurring service revenues. Our aviation contracts open up avenues for additional revenue through follow-up training, hardware maintenance, spare parts, and upgrades to our automated threat detection algorithms. Similarly, some of our border and cargo security clients, aside from seeking these types of services mentioned, also utilize a proprietary search scan multi-site integration platform. This platform allows us to increase future revenues through new user licenses and software upgrades. Our inspection systems have a typical life cycle of seven to 10 years, thereby creating predictable stream of ongoing recurring service revenues. Lastly, we announced a $23 million order to support deploying and integrating long range radio frequency critical communication systems. As part of the award, we're expected to provide essential hardware and technical services to enhance the US government's strategic RF communication capabilities in a critical region. This is an excellent win for us in our recently acquired RF Solutions business. Furthermore, we are optimistic that we can enhance this business in the marketplace by utilizing our global reach across regions. and offering solutions to customers with critical security communication and surveillance requirements. Our security pipeline includes a wide range of opportunities, both internationally and domestically. Moreover, domestic growth could accelerate driven by the new administration's national security policies. With both major political parties supporting enhanced border security, we are well positioned to play a key role. Our non-intrusive inspection technologies are ideally suited to bolster security at airports, ports, borders, and other critical infrastructure points. Overall, while product revenue growth has been robust, we expect service revenue as a percentage of overall security revenues

to increase and these historically have a higher margin. Moving on to Optoelectronics.

speaker
A.J. Mehra
President and CEO

Optoelectronics delivered another impressive quarter on modest top line growth, achieving a quarterly record with 101 million in revenues. This record was in part driven by a flex circuit operation that serves consumer and medical technology customers was a major contributor to Q2 growth. Based on Opto's recent trends and our dialogues with key OEMs, we believe that the phase where many customers were adjusting inventory levels and tempering demand forecasts is now mostly in the past. During the quarter, we announced an $11 million order to provide critical electronics sub-assemblies for long-standing healthcare OEM customers. We also announced an order for $6 million from a different healthcare OEM to provide optical sensors for its patient care devices. These orders exemplify the kind of repeat business we consistently secure from established customers, accounting for approximately 80% of this division's total revenue. We are actively working with clients looking to diversify away from China by relocating component or value-added manufacturing to our international facilities. Given our current demand visibility, we anticipate the Opto division will deliver a robust performance in the second half of the fiscal year. And finally, let's discuss the healthcare division, where Q2 revenues grew 7% year over year with improving profitability although less than we typically see. It was nice to see a return to growth in healthcare, indicative of a pickup in order activity from hospitals and solid execution of a sales strategy built around a clinical workflow and predictive analytics solutions. During the quarter, we announced a $6 million order from a US-based hospital system to provide patient monitoring solutions and related supplies, We expect to provide a range of patient monitoring solutions and accessories to support this customer and others. While we continue to invest in developing new products, including our next generation platform, we are intently focused on driving growth and improving the overall operating performance of our security division. On a personal note, I'm honored and excited to begin the president and CEO role at OSI. The company has a critical mission to support the global community's safety, security, and well-being. Having been part of this company's journey, I have seen the potential in all of our operational divisions and the talented individuals who have been key to our success.

speaker
Alan Edrick
Executive Vice President and Chief Financial Officer

Thank you, AJ. Now I will review in greater detail the financial results for the fiscal 25 second quarter. As previously mentioned, Our Q2 revenues were up 12% compared with revenues in the second quarter of the prior fiscal year. This increase was primarily driven by our largest division security. The 16% year-over-year increase in Q2 security division revenues was fueled by growth in aviation and checkpoint product sales, including strong growth in trace detection system sales. Q2 revenues included continued shipments from the $200 million-plus cargo contract and also from our two contracts with Sedena in Mexico. In addition, the business acquired at fiscal Q1 is gaining momentum and contributed to the security division revenues nicely. Third-party opto sales were solid, delivering a 4% year-over-year increase, driven by growth from our flex business as well as others. The right sizing of inventory levels as AJ mentioned, with our Opto customers, is largely complete. And we anticipate an acceleration of the revenue growth rate in the Opto division as early as Q3. And the healthcare division returned to growth, reporting a 7% increase in year-over-year sales in Q2. The fiscal 25 Q2 gross margin of 35.1% was solid. Our gross margin in Q2 last year of 37.9% was the strongest in any quarter of fiscal 24 due to very favorable product mix and security. Our gross margin will generally fluctuate from period to period based on revenue mix and volume, impacts of changes in supply chain costs, effects in inflation, among other factors. Moving to operating expenses, Q2 SG&A expenses were $71 million, or 16.8% of sales, compared to $72 million, or 19.2% of sales in Q2 of the prior year. The 240 basis point improvement resulted from leveraging our fixed cost structure and maintaining strong discipline in managing such costs. We worked diligently across each of our divisions to improve efficiency and manage our SG&A cost structure. Research and development expenses in Q2 of fiscal 25 were 18 million, or 4.3% of revenues, compared to 16 million, or 4.4% of revenues in the same prior year quarter. We continue to dedicate considerable resources to R&D, particularly in our security and healthcare divisions, as we remain focused on innovative product development, which we view as vital to the long-term successes of our businesses. We recorded $0.2 million restructuring other charges in Q2 of fiscal 25 compared to $1 million in the same quarter of the prior year. Moving to interest and taxes. Net interest and other expenses in Q2 fiscal 25 increased to $8.6 million from $6.5 million in Q2 fiscal 24, primarily due to a higher amount of borrowings associated with the investment in working capital for the sales growth, an acquisition completed in Q1, and stock buyback partially offset by the favorable impact of the convertible notes issued during Q1 which were partially used to repay higher cost borrowings. Our reported effective tax rate under GAAP was 23.3% in Q2 of fiscal 25, compared to 20.2% in Q2 of last year. However, excluding the impact of discrete tax benefits, our normalized effective tax rate, which is the rate reflected in our calculation of non-GAAP adjusted EPS, was 24.0% in Q2 fiscal 25, compared to 25.8% in Q2 of 24. I'll now turn to a discussion of our non-GAAP adjusted operating margin. Overall, our adjusted operating margin in the second quarter of fiscal 25 was a solid 15.0%, up sequentially from 10.3% in Q1. This quarter faced a tough comp, as Q2 in fiscal 24 was 15.5%, which was the strongest adjusted operating margin quarter of FY24. The Q2 adjusted operating margin in the security division was 19.9%. Although down year over year due to this tough comp, this represented the second strongest adjusted operating margin in the security division's history. Due to a ramp up of newer opto operations, the opto division's adjusted operating margin was 12.8% in the second quarter of fiscal 25 compared to 13.4% in last year's Q2. We anticipate nice adjusted operating margin expansion in opto in the second half of fiscal 25. The healthcare division's adjusted operating margin, while lighter than we would like, still increased 300 basis points year over year. Moving to cash flow. Q2 marked a return to significant cash flow with cash provided by operations of 53 million. CapEx in the 25 second fiscal quarter was 5.5 million. while depreciation and amortization expense in fiscal Q2 was 10.6 million. We saw a nice improvement in DSO in Q2, as solid collections led to a 16% reduction in DSO from Q1. As we mentioned last quarter, our receivables and DSO are both above typical levels, mainly because of the timing of billings and collections for our significant international security cargo contracts. For these contracts, Billing is triggered by the achievement of significant project milestones, which are highly influenced by the customer's timeline and sign-off. So under GAAP, we record an unbilled receivable for revenue earned and then bill and collect cash subsequent to the achievement of the relevant milestone. Note, while unbilled receivables are elevated relative to historical levels and represent a significant source of future cash flow, The balance decreased by 19% at the end of Q2 versus the end of Q1. We continue to anticipate operating cash flow could be significant in the second half of fiscal 25. Our balance sheet is solid with net leverage of approximately 2.1 as calculated under our credit agreement. Aside from 7.5 million of annual required principal payments under our bank term loan, the bulk of our bank debt matures in fiscal 27. We estimate over 70% of our debt was fixed versus floating at the end of Q2 of fiscal 25. And finally, turning to guidance. We are increasing our fiscal 25 revenues in non-GAAP diluted EPS guidance. For the full fiscal year, we anticipate revenues in the range of $1.685 billion to $1.710 billion, increasing our guidance on year-over-year revenue growth to a range of 9.5% to 11.1%. We are also increasing FY25 non-GAAP adjusted earnings per diluted share guidance to a range of $9.10 to $9.40 per share, representing 11.9 to 15.6% growth. This fiscal 25 non-GAAP diluted EPS guidance excludes potential impairment restructuring and other charges, amortization of acquired intangible assets and their associated tax effects, as well as discrete tax and other non-recurring items. We currently believe this guidance reflects reasonable estimates. The actual impact on the company's financial results of timing changes on the expected conversion of backlog to revenues and new bookings is difficult to predict and could vary significantly from the anticipated impact currently reflected in our guidance. Actual revenues and non-GAAP earnings per diluted share could also vary from the guidance indicated above due to other risks and uncertainties discussed in our SEC filings. We continue to remain focused on the growth of our businesses. We believe our efforts will enable OSI to continue providing innovative products and solutions. We'd like to take this opportunity to thank the global OSI team for its continued dedication in supporting our customers and partners. And at this time, we'd like to open the call to questions.

Thank you. And as a reminder, to ask a question, simply press star 11 on your telephone and wait for your name to be announced. To remove yourself, press star 11 again. One moment for our first question. It comes from the line of Josh Nichols with B. Riley. Please proceed.

speaker
Josh Nichols
Analyst at B. Riley

Yeah, thanks for taking my question. And, AJ, congratulations on the new role. Things are off to a great start. Looking, you touched on it briefly, I think, but while it's early days, the new administration clearly has an increased focus on border security. Any context you could provide around the potential increase in opportunity versus what you're currently doing on the U.S. border front and how that could change if there's some increased allocations to budgets for some of these three-letter agencies that are going to be doing a lot of the border security as there's an anticipated ramp up over the next few years, presumably?

speaker
A.J. Mehra
President and CEO

Josh, this is AJ. Thank you. So, you know, great question. You know, it's been three, not even three days, but I think, as you know, that border security really is a bipartisan issue. And there's been a lot of movement, both on the House and on the Senate, trying to reconcile the bills, which are substantially higher than what they were previously in terms of total funding. So we think with the new emphasis with the new administration. It's positive. We believe that the technology that we provide, and not just the technology, but some of the software like CertScan, which we're able to really go in and look to see if drugs, the wrong people are coming in, is really a plus for us. We are the dominant player with CBP. And we feel very good as we go forward. And I think that we'll see more and more over the next three, six months.

But all indications from our end are positive.

speaker
Josh Nichols
Analyst at B. Riley

Thanks for the context. And then just a little bit deeper, I mean, on the recent acquisition, the RF Solutions business seems to be that that business is already doing pretty well. I noticed the company secured, I think, a $23 million award already. Could you talk a little bit about some of the opportunities that you see layering this into OSI systems, given that you have a much larger global sales infrastructure and the opportunity to kind of expand the revenue base relative to what it was currently doing before you acquired the business?

speaker
A.J. Mehra
President and CEO

I think you kind of answered your question. over there because, yes, one of the advantages that this company has now is it's got the OSI's financial muscle as well as the different areas that we are in all over the world. So we definitely are going to help them. We are integrating them, working very closely. I mean, just keep in mind they're in the defense sector. but also their over-the-horizon radar, it's really crucial for border security and drug interdiction. Keep in mind that, you know, these radars provide broad-range base surveying systems that enables tracking of aircraft, drones, surface ships in designated zones around the U.S. border. And we feel that's an opportunity as we go forward besides, obviously, their traditional opportunities in defense. So we are talking to the customers, and we have had a very positive response. Also, I think from an OSI perspective, we have customer base, which is very similar to theirs, but it's got us deeper into those customers. And more and more, we have more to discuss with them. So we're not just discussing scanning, but we're discussing how we

Thank you. One moment for our next question, please. It comes from the line of Mariana Perez Mora with Bank of America. Please proceed.

speaker
Mariana Perez Mora
Analyst at Bank of America

Hello, everyone, and thank you for taking my question. So the first one is going to be around Mexico, and I appreciate the details you give in the prepared remarks. But, like, could you please describe how much of a contribution Mexico was to the quarter, and how should we think about that going forward, at least in the second half of the year? I see that book-to-bill was really strong in the quarter, and you also had, like, a really strong start to the year with orders. So is that enough to affect any –

speaker
Alan Edrick
Executive Vice President and Chief Financial Officer

slow down in terms of like recognition of them of the Sedina contracts or like how should we think about that transition thank you hi Mariana this is Alan good question you know the Mexico contract was a significant contributor to us in the in the first half of the year in the second half of the year it's anticipated to continue to be a significant contributor but at a lighter amount than we saw in the second half of fiscal 24. With the very robust backlog in the strong opportunity pipeline, we're effectively replacing the strong Mexico revenues that we had in Q3 and Q4, a portion thereof, with non-Mexico contracts. And we feel extremely, extremely confident about that. So really a robust opportunity set. Mexico is important to us. But as we have said, we shipped a significant amount last year, shipping a significant amount this year, but we are really well positioned for the future because we have such a strong backlog of non-Mexico business and such a strong opportunity set as well.

speaker
Mariana Perez Mora
Analyst at Bank of America

Thank you. And then when you think about this transition, especially because the early stages of this contract were mostly products, how should we think about the products versus services mix? Second quarter and probably in the trend towards the next 12 months.

speaker
A.J. Mehra
President and CEO

So this is AJ. I think that if you look at the product that's getting shipped, we always say that one of the things, the products that we ship leads us to recurring service revenue. So we feel... really into 26 and really 27 and beyond, that we're going to see some very good recurring revenue for service. All these products have to be serviced in Mexico, for example. So that revenue will continue. And as I mentioned earlier, that service revenue has very good margins. So we're fully expecting that.

speaker
Alan Edrick
Executive Vice President and Chief Financial Officer

And maybe to supplement that, this is Alan, we've had significant product revenue growth over the last few years. And as those products are now beginning to roll off a warranty and create service revenue, as AJ described, we expect to see real strong service revenue growth at the higher contribution margins beginning as early as now, this sort of Q3. So it's a nice position to be in with a strong installed base that we put out there.

speaker

Moving to this more recurring revenue at higher margin is a nice position to be in.

speaker
Mariana Perez Mora
Analyst at Bank of America

Thank you. And one more from my end. I was curious, part of this radio frequency critical communications award that you got, how much of that is incremental to the portfolio you acquired? And how much is more like a recompate of what the existing portfolio was?

speaker
A.J. Mehra
President and CEO

Well, I think there's always incremental business, but this one is new. as we move forward. So we're actually looking not just to get the incremental business, but get the growth, as I mentioned earlier, with having the OSI muscle behind us and being able to not just get into the defense side, but maybe also the border security side where we can see new business. And we're very focused on maintaining the business that we have, getting that business, but looking at new opportunities.

Thank you. One moment for our next question. That comes from Larry Solo with CJS Securities. Please proceed.

speaker
Larry Solo
Analyst at CJS Securities

Great. Thank you. AJ, I welcome you, congratulate you on your new role as well. I guess first question for you, AJ, you mentioned sort of this expanding opportunity pipeline. And, you know, you've spoken a lot about most of your kind of end markets and verticals. I'm just curious if any of those verticals stand out where there's more opportunity for expansion going forward. I mean, obviously, we've talked a lot about ports and borders, and it does sound like the new administration, you know, we're bipartisan, so maybe not a significant real change there, although maybe headlines sound like it will change. But, you know, maybe just the question is, is the new administration driving these new expanding opportunities, or where are you seeing kind of, you know, outsized opportunity growth?

speaker
A.J. Mehra
President and CEO

So I think, you know, thank you, first of all, Larry. But, you know, the growth is across the board. So, yes, we talk about borders. That's in the news. Sure, we think we're going to see growth. A lot of it is just starting. And as Alan pointed out, it's not just about the initial product, but it's about What else can we do? Can we integrate some of it with our cert scan software, get recurring revenues, get the service revenue? Aviation is huge. Internationally, you know, we have a lot of opportunities. We've announced a couple of orders, and we feel on the check baggage as well as the checkpoint, there are a lot of opportunities. TSA, as you know, they've had some changes there with a new administrator coming in. We don't know who that's going to be. But their check baggage, which we have an excellent product in our RTT, those are, you know, in some cases 20-plus years old. So they have to replace those probably in the next, you know, two, three, four years when they start. Their trace systems, where we participate in. And these are huge opportunities, not just in the U.S., but internationally. And I think as you look at the opto side, You know, we keep on, we talk about security, but the moving away from China manufacturing, we as a company are uniquely situated with a lot of international facilities that we have around the world where we can accommodate that. And really, you know, we do business with a lot of defense companies on the security side and opto side. And I think we can really merge those opportunities and go talk to the customers as a large company who's unique in providing obviously the security side, but the ability to manufacture on the opto side. And medical for us, we're investing a lot of money in the next generation products, looking at how we broaden that product line, just like we're doing in security. So we feel very good about all the growth opportunities. So I would not just say it's just on ports and borders, That's one very significant pillar, but there's a lot more out there.

speaker
Larry Solo
Analyst at CJS Securities

Right. And on the ports and borders in particular, it feels like you've announced several larger-sized fields. Most of them were actually international. I'm just curious, do you feel like you've got a bigger opportunity now? Well, obviously international is a bigger geographical region, but the U.S. to me seems like maybe it's lower on your proportion of what's driving ports and borders today. Is that a fair statement?

speaker
A.J. Mehra
President and CEO

You know, I think that U.S. is just as important, if not the most important to us. As you look at it, we've been driven a lot internationally, but we have these IDIQs with CBP, for example, and, you know, I think there are going to be new IDIQs coming in. We have worked very closely with CBP and other organizations where we develop new products. They're coming out. We have the largest... share of the market in the U.S., and we feel as the next generation products come out, which we've developed very closely talking to our customers, so it's not just something we're coming out with, and integrating the hardware with the software where it makes it easier for people to look for contraband, etc., And keep in mind, a lot of people just look at security as an expense. But at the end of the day, when we introduce these products, and I'm not going to go into some specifics for competitive reasons, but it really facilitates the trade coming through the borders. And in the end, it's really cheaper overall for the consumer at the end of it. So a lot going on, but the U.S. is important. I think there's a good opportunity for the next several years.

speaker
Larry Solo
Analyst at CJS Securities

Gotcha. And if I may just squeeze in, Al, a question for you just on the margin security. Like you said, the gross margin was down year over year because of the mix. But if we just look sequentially, it looks like your services revenue were about flat and your margin went up like 550 bits. Is that mostly just on the SG&A leverage on the higher revenue? Is that, I guess, the biggest driver or the predominant driver?

speaker
Alan Edrick
Executive Vice President and Chief Financial Officer

Yes, Larry, it really is. You know, the economy is a scale as we leverage our fixed cost structure. So that is really kind of what drove it on a sequential basis for OSI Systems overall. You're exactly right.

speaker
Larry Solo
Analyst at CJS Securities

Gotcha. And then just lastly, on the opto division up 4% in the quarter, a nice return to growth in the first half. You mentioned a lot of qualitative things, you know, obviously on-shoring. I know you have a new facility in Mexico. What's the kind of driver of, you mentioned, margin expansion in the back half of the year. Is that also just on operating leverage or any color on that would be great?

speaker
Alan Edrick
Executive Vice President and Chief Financial Officer

Thanks. Good question, Larry. This is Alan. So I'd say really what's going to drive the accelerated growth in opto as we expect in the second half of the years is a few fold. One is kind of the right sizing the inventory levels is largely behind us. So we're now seeing customers return to their normal ordering patterns and in fact our book to bill in opto in our second quarter was north of one as well. So we expect that to drive accelerated growth. You mentioned the new operation that we have in Mexico. That is gaining momentum also, which will certainly help. The mix of business is expected to be favorable for us in the second half, which should also drive some margin expansion. So all in all, we expect to see some nice top line growth coupled with operating margin expansion in the second half for the Opto division.

Larry Solo

Great. Thanks, Alan. I appreciate it.

Thank you. Our next question comes from the line of Christopher Glenn with Oppenheimer. Please go ahead.

speaker
Christopher Glenn
Analyst at Oppenheimer

Yeah, thanks. I'm curious. I just want to dive into the aviation sector a little bit. And welcome, Ajay. Good to hear you on the call. Curious, you know, would you call the global kind of replacement and upgrade cycle in aviation in its early days? I know the U.S. is sort of lagging the international, but maybe kind of an innings rating for the international and the total global on that. And are you seeing improving wind rates in aviation versus historical?

speaker
A.J. Mehra
President and CEO

Thanks, Chris. You know, it's an interesting question because, you know, aviation is such a big market. And when you look at aviation, you've got checkpoints. Within checkpoints, you have, you know, your checkpoint CT systems where you put your baggage through. You have people screening. You have trace. You have so many different products out there. And then obviously you have your check baggage. So coming to the U.S., the U.S. has been focused on Checkpoint CT, I think as we move forward, they are definitely going to look to see what they do in trace, which we are a very significant player and I believe one of the leaders. RTT on the check baggage is definitely a big opportunity for us as well. And we feel that TSA is going to have to look at potentially upgrading, replacing some of these products Starting a couple of years from now, so that's maybe three years from now, but that's where the market is, and we feel that we're in a good position to participate. Internationally, we're winning a lot of orders. It's a big market. Obviously, we are in the checkpoint as well as check baggage as well as trace. We have bundled some of the products. Customers know us very well. And then market is, you know, in some places it's starting, some places it's in the middle. And as, you know, keep in mind, as you get towards the end, another cycle starts. So it's the continuing cycles, not just, you know, you fill this up and it's going to go away. You know, it's almost like a car, you know, you're going to have a car. I told you, I mentioned, I believe in my prepared remarks, that was seven to 10 years was what, you know, what some of this equipment is there for. In aviation, depending on technology, it might even be in some cases a little faster or a little slower. So it's a continuing business, and the key thing over there is as we get into this business, there is recurring service revenue as we move forward. So it is really, there's no one answer beginning and end. middle, it's really a continuing business, the best way to answer it.

Christopher Glenn
Analyst at Oppenheimer

Great. That's really helpful for understanding that. And then you mentioned the bulk of the debt coming due, and I'm not sure if you said fiscal 27 or calendar 27, but what are you anticipating for pricing or timing as you redo that? How far ahead are you interested in addressing that?

speaker
Alan Edrick
Executive Vice President and Chief Financial Officer

Hey, Chris. This is Alan. So, yeah, the credit facility, which is sort of our natural five-year credit facility, matures in December of 26, which is our fiscal 27. Throughout the course of calendar 25, we'll be working with our banks, as we've done numerous times in the past, to likely amend and extend the credit facility. As you may know, even though we're not an investment-grade company due to our size, we have investment-grade pricing. as it comes to the credit facility, so quite favorable for us.

Thank you. Our next question comes from the line of Matt Akers with Wells Fargo. Please proceed.

speaker
Matt Akers
Analyst at Wells Fargo

Hey, good morning, guys. Thanks for the question, and congrats, AJ, on the new role. I wanted to ask about cash. You know, good to see, you know, positive cash flow in the quarter. some of that working capital reversing. I know, Alan, you mentioned the back half continuing to see pretty good cash. I'm just curious, should we see that as still kind of lumpy around maybe some of these milestones of some of the big international products, or are we to the point now where that's kind of a steadier free cash flow here going forward?

speaker
Alan Edrick
Executive Vice President and Chief Financial Officer

Yeah, Matt, good question. This is Alan. it'll never be a sort of a steady pace of cashflow within the likes of our business. We'll always have some quarters that are, that are much stronger and some quarters that are, they're a little bit lighter. Uh, we have an opportunity to continue to sort of outperform on a cashflow basis with a strong free cashflow to net income conversion rate, given that we have some money, uh, sort of tied up in working capital. So as the receivables begin to normalize, as does the inventory, there's opportunity for significant free cash flow generation. And we expect to see that in our second half and as we move into fiscal 24 and forward. So we think we'll continue to have a good free cash flow conversion rate, though it's never going to be perfectly smooth due to kind of the nature of our business and some of the international contracts that we have. Yeah, got it.

speaker
Matt Akers
Analyst at Wells Fargo

Okay. I wanted to ask about tariffs. You know, given how that's been kind of a topic with a new administration, just curious how you think about any risk associated with either, you know, prices due to tariffs or, you know, customers. You guys have a lot of international business, you know, Mexico, for example. Just how you're kind of thinking about the risk around that.

speaker
A.J. Mehra
President and CEO

You know, it's a question that is on, you know, a lot of people's minds, obviously. I think it's a little too early to tell, you know, what's going to happen. But I will say, you know, from a OSI perspective, you know, we're well situated because, you know, we have manufacturing facilities in the U.S., we have manufacturing facilities in Europe, Asia, and, you know, we have the flexibility to turn things around and really work closely with our customers on what their needs are and if they need to address any tariff situation. So I think at this point, it's a wait-and-see attitude, but I think it's much more of a challenge for companies that are manufacturing only outside the U.S. and importing into the U.S., For us, you know, like I said, it's much more flexible, and we have the ability to really switch manufacturing to different locations. So, you know, we'll watch it just like everybody else is watching it. Yeah, great. Thank you.

speaker
Matt Akers
Analyst at Wells Fargo

And then if I could squeeze one last one in. I guess maybe any way to think about the seasonality between Q3, Q4. I think, Alan, as you mentioned, Q2 last year margins kind of unusually strong. Just anything to think about it as we go into the back half?

speaker
Alan Edrick
Executive Vice President and Chief Financial Officer

Yeah, Matt, good question. We would see the back half weighted a bit more to Q4 as we typically do. Q4 tends to be our strongest quarter at the end of the fiscal year. As a result, we would see our revenue stronger there. And from a margin mix perspective, we would expect to see the operating margins stronger in Q4 than in Q3.

Thank you again. And as a reminder, if you do have a question, please press star 11 to get in the queue. One moment for our next question. We have a follow-up from the line of Mariana Perez with Bank of America. Please proceed.

speaker
Mariana Perez Mora
Analyst at Bank of America

Thank you and hello again. So I have a follow-up to Matt's question. When we think about balance sheet and free cash flow, How should we think about receivables going forward and especially the unbuilt receivables balance?

speaker
Alan Edrick
Executive Vice President and Chief Financial Officer

Hi, Mariana. It's Alan. So we would expect that our DSO is going to improve going forward. Of course, we expect to grow the top line. So in absolute dollars, receivables could grow from time to time, but we'd expect to see our DSO down. With respect to unbilled receivables, we were really pleased to see a 19% decrease in our unbilled receivables from the end of Q1 to Q2, which is what we were anticipating. I believe as we get to the end of the fiscal year in June, we'll see those unbilled receivables significantly down from where they are today. And as we move the unbilled receivables to build receivables and therefore cash collection, that's what should drive sort of this outsized free cash flow for us as well. So a real nice position to be in for us.

speaker
Mariana Perez Mora
Analyst at Bank of America

Thank you. And one more on the contribution from the acquisition. Have you measured how much was it per share?

speaker
Alan Edrick
Executive Vice President and Chief Financial Officer

Not per share. We did roughly $17 million of revenues in the quarter, so it performed quite nicely for us.

And thank you for one moment for our next question, please. And he comes from the line of Jeff Martin with Roth Capital Partners. Please proceed.

speaker
Jeff Martin
Analyst at Roth Capital Partners

Thanks. Hi, Alma, AJ. Somehow I got mixed up in the queue apparently. Wanted to dive into the surveillance business that you acquired in September a little more. In terms of product portfolio, are there things you can do to enhance that offering? Is it where it should be? Do you need to invest significantly in R&D? And are there complementary products that are either in the existing security product portfolio or that you might look to acquire in the future to enhance that?

speaker
A.J. Mehra
President and CEO

So, Jeff, I think I went into it a little bit, but just to reemphasize why this made sense was, number one, the customer base that they have. in the U.S. with DOD and obviously internationally is really something that we're very familiar with, and we're able to go and talk to those customers and really expand our offering. You go and look at, you know, some of the products that they have. I mentioned the over-the-horizon radar. Obviously, what everybody looks at at over-the-horizon radar is for, you know, drones and missiles, like what's going on in Ukraine. Everybody was looking at ballistic missiles coming through. And that's where satellites would pick up. But cruise missiles and drones are causing just as much damage. So there's a big opportunity for traditional over-the-high radar to be there. Having said that, it really applies very closely, like I mentioned, to what we do is border security because these radars can be used for, you know, ships, vehicles, drones coming across the border, carrying all kinds of, you know, drugs and anything else. And the capabilities of drones from a payload is going to get bigger and bigger. So I think that's going to become a definitely more and more of a threat. And then traditionally, you know, they're in other defense areas like they're, ULF, which is ultra-low frequency, which is really for communication off, you know, for submarines when they're underwater. That's the only form of communication that they really have. And there are opportunities in space and others, but really the key opportunity for us is providing them with the capabilities from a financial standpoint, from a reach standpoint. and really working much closer with some of the larger companies, defense contractors out there. As far as the question on R&D, they spend money on R&D, but a lot of that R&D is funded by their customers. So we think it's a very good fit, and the opportunities are definitely there, and we'll keep you informed over the next several quarters, but we feel good about it.

Jeff Martin

So the security and the opt-out have been covered pretty extensively. So, you know, I'll throw a healthcare division question out there. I know you've been working on, you know, a next generation patient monitoring system for several years now. Are you at a point where you can kind of give a timeline on, you know, what the rollout of that new platform looks like and, you know, You also have mentioned in the past that you're evaluating the leasing model within the industry, which could be a differentiator. And just maybe give an update if that's gained much traction or if that's more pinning the launch of the new patient monitoring platform.

speaker
A.J. Mehra
President and CEO

So, you know, I think that we're actually spending considerable resources on the new platform with our R&D team. I'm not going to give you an exact timing, more for competitive reasons than anything else. But we think that it's, you know, 26 and beyond. But we feel good about, you know, what we're hearing, what progress we're making from that standpoint. And really, it's not just over there, but some of the other items and other products that we're able to offer besides our Next Generation platform. whether it's remote monitoring, whether it's predictive analysis, et cetera. So all that really goes together. And the objective is that we become, from a technology as well as from a sales standpoint, it gives us a good boost down the road. But exact timing, like I said, as we start introducing the products, we'll give you more color on that.

speaker
Jeff Martin
Analyst at Roth Capital Partners

Great. And then last question for me on the turnkey side, you mentioned existing customers are happy, things are going well there. Are you seeing much opportunity to expand the customer base within turnkey solutions offering?

speaker
A.J. Mehra
President and CEO

The short answer is yes, we're working on several opportunities. You know, like, you know, these are, these are not opportunities that happen in a couple of months. You know, in some cases you have to work with a, You know, you have to work with the international governments. You have to basically, you know, go through and educate them on the whole process. So it's, you know, it takes quite a while to get through it, but we are actively working on several opportunities right now. Excellent. Thank you.
