Speaker 1
Thank you. Good afternoon, and thank you for joining us. I'm Alan Edrick, Executive Vice President and CFO of OSI Systems, and I'm here today with Ajay Mehra, OSI's President and CEO. Welcome to the OSI Systems Fiscal 2026 First 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 2026 First Quarter financial results. Before we discuss these results, 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 in this call are based on currently available information, and the company undertakes no obligation to update any forward-looking statement based on subsequent events or new information or otherwise. During today's call, we will be discussing the company's results using both GAAP and non-GAAP financial measures. For more details on these non-GAAP measures, their comparable GAAP measures, and a quantitative reconciliation of the two, please refer to today's earnings release. I will begin with a high-level summary of our financial performance for the first quarter of Fiscal 2026 and then turn the call over to Ajay for a discussion of our business and operational performance. We will then finish with more detail regarding our financial results and a discussion of our increased guidance for Fiscal Year 2026.
We delivered strong first-quarter financial results, setting multiple Q1 records across key metrics, and we are excited by the momentum across our businesses. Now for the high-level summary of our Q1 results. First, revenues increased 12% year-over-year to a Q1 record of $385 million. Each of our three divisions achieved double-digit top-line growth, highlighted by a 13% increase in revenues in the Security division. This top-line performance is especially noteworthy given that the prior year Q1 included substantial revenue from major security programs in Mexico. Excluding contributions from those Mexico contracts and revenues generated by businesses acquired in Fiscal 2025, our underlying consolidated revenues grew roughly 26% in Q1, highlighting robust organic demand across our core businesses. Second, the solid revenue growth led to record Q1 non-GAAP adjusted EPS of $1.42.
Third, Q1 bookings were strong, and with a book-to-bill ratio of approximately 1.1 in the quarter, we finished with a record Q1 backlog approaching $1.9 billion. This backlog, coupled with a robust pipeline of opportunities, provides good visibility as we continue into Q2. Before diving more deeply into our financial results and discussing our outlook for Fiscal 2026, I will turn the call over to Ajay. Thank you, Alan. Good afternoon, everyone. I want to start by recognizing the outstanding performance of our global OSI team in delivering a record-breaking first quarter. Our results this quarter reflect the strength of our diversified business model and our relentless focus on innovation, operational excellence, and customer satisfaction. As Alan mentioned, we achieved 12% revenue growth with solid earnings.
Furthermore, our service revenues grew 23% during the quarter, as many of our product installations over the last few years are now generating recurring revenue from ongoing service and support. We closed the quarter with a record Q1 backlog and feel confident about the future outlook. Let's jump into the performance and key highlights across our three divisions for the first quarter, starting with our Security division. Q1 revenues in this division were $254 million, a solid 13% year-over-year growth. Bookings were strong, resulting in a record Q1 Security backlog, setting a strong foundation for continued growth. During the quarter, we continued to successfully perform on our port and border security contracts with Mexico. However, as Alan will elaborate shortly, the impact of these contracts on our overall business has moderated. It has been more than offset by robust growth across other areas of our diverse Security portfolio.
This dynamic was evident in Q1, where revenues from our aviation, cargo, and RF detection offerings, including service, drove double-digit overall growth. Our customers have witnessed a proven expertise in system integration, maintenance, operator training, and long-term support, all of which optimize the performance of our inspection equipment during its lifecycle. We have also effectively built on our turnkey offerings to strengthen our position in global equipment tenders for ports, borders, and airport security. As I noted earlier, our bookings remained robust, with a book-to-bill ratio of 1.1 in the Security division, supported by several significant wins, some of which we announced recently. We announced approximately $75 million in non-intrusive inspection product and integration orders, and more than $60 million in RF product orders that we received during Q1. These orders reflect our growing momentum in critical areas such as cargo and vehicle inspection and advanced RF detection technologies.
More importantly, they reinforce the stability and depth of our relationships with our customers. Driven by factors like geopolitical conflicts, terrorism, and crime, governments worldwide are investing heavily in advanced systems to enhance detection, deterrence, and response capabilities. These escalating global threats are being addressed by increasing focus on technology innovation and, in turn, shifting policy priorities supported by targeted funding. During the quarter, we also announced an award of a five-year contract from U.S. Customs and Border Protection (CBP) for its NII Common Integration Platform Program, also referred to as SIP. The SIP program is designed to enhance national border security by enabling sufficient screening and strengthening collaboration among CBP, the Department of Homeland Security, and other stakeholders. We are providing our Search Scan Platform to support CBP's strategic goals by modernizing its inspection capabilities.
Therefore, as part of the SIP program, we will support various integration efforts, not only on our platforms but also with inspection technologies and solutions from other providers. This SaaS-based offering is expected to increase annual recurring revenues over time. We're also gaining significant traction in our RF product line and anticipate further momentum from opportunities tied to Golden Dome initiatives-related expenditures highlighted in the One Big Beautiful Bill. Once the government resumes full operations, we anticipate a heightened demand for a number of our core offerings. The successes in Q1 instill great confidence in our robust growth prospects as we advance through the remainder of Fiscal 2026 and beyond. Turning now to our Optoelectronics division and manufacturing division. Opto delivered record Q1 revenues, including intercompany sales, while achieving strong profitability.
We experience notable strength and expansion across our product lines in North America, where many of our customers are leading OEMs in their industries. Our operations in Mexico continue to play an important role amid ongoing global tariff uncertainties. We fielded numerous inquiries from both existing and prospective OEMs seeking to realign their supply chains toward the U.S. and near-shore options. Our robust global manufacturing footprint, spanning North America, Europe, and Southeast Asia, positions us as a compelling alternative for capitalizing on this potential supply chain shift. Finally, turning to our Healthcare division. Q1 sales rose a solid 10% year-over-year. As we've discussed on prior calls, we're executing on the improvement plans we put in place under a new leadership team and beginning to see tangible benefits in both sales and operations.
That said, while this Q1 performance reinforces that we are on a good path, we still have a considerable way to go before meeting our high performance standards. Looking ahead, we'll continue to drive product innovation in Healthcare with continued R&D investments while advancing operational efficiencies to enhance profitability. In summary, OSI Systems has tremendous momentum. We are a thriving business. Diverse and substantial backlog, and a robust balance sheet that supports both organic growth and strategic investments. We remain disciplined in managing our cost structure. We expect to generate strong cash flow this year, which, combined with our ample credit capacity, affords us significant flexibility in capital allocation. I want to thank our employees, customers, and shareholders for their continued support. With a strong foundation and expanding opportunities, we are well-positioned to deliver long-term value.
With that, I will turn the call over to Alan to discuss our financial performance and updated guidance in more detail before opening the call for questions. Thank you. Thank you, Ajay. Now I will review in greater detail the financial results for the first quarter and then discuss our increased Fiscal 2026 guidance. As mentioned, our Q1 revenues were up 12% compared to the first quarter of the prior fiscal year, with strength across the three segments. Security division revenues in Q1 were $254 million, an increase of 13% year-over-year. This growth was driven by higher service revenues, robust sales of aviation and checkpoint products, and increased revenues from the RF business acquired in Q1 of Fiscal 2025.
As expected and directionally similar to last quarter's trend, revenues related to our large Mexico security contracts decreased to $25 million in Q1 of Fiscal 2026 from $70 million in Q1 of the prior fiscal year. Excluding acquisition-related growth and the Mexico contracts, Security division revenues surged 39% year-over-year, clearly reflecting healthy demand across the broader security portfolio. Meanwhile, our Optoelectronics and Manufacturing division had another excellent quarter. Opto sales, including intercompany, increased 12% year-over-year to $110 million, which is a new Q1 record for this division. This was driven by growth across our diversified product and customer portfolio. Following a difficult Q4, Healthcare division sales, driven primarily by international revenue activity, bounced back, posting 10% year-over-year growth. Our Q1 gross margin was 32%.
This was down from the same quarter in the prior year, as a less favorable revenue mix on product sales outweighed an increase in gross margin from higher service revenues. Our margins can fluctuate based on the product and service mix, volume, supply chain cost, FX, tariffs, among other factors. Moving on to operating expenses. Selling, General and Administrative expenses in the 2026 first fiscal quarter were $67 million, or 17.4% of sales, compared to $72.2 million, or 21% of sales in Q1 last year. The reduction was aided by more favorable FX in Q1 this year compared to Q1 in the prior year. We continue to work diligently across all divisions to manage our SG&A cost structure efficiently as we grow. R&D expenses in Q1 were slightly above $20 million, or 5.3% of revenues, up from $17.8 million, or 5.2% of revenues in the same quarter last year.
This increase reflects our decision to invest in innovation, yielding market-leading products, particularly in Security, and positioning OSI Systems, Inc. well for the future. We expect to continue this heightened focus on R&D to advance key projects through the remainder of Fiscal 2026. Even with these investments, our combined SG&A and R&D expenses as a percentage of sales have decreased annually for each of the past eight years, and this trend is anticipated to continue for Fiscal 2026, underscoring our ability to drive operating efficiencies while still funding growth initiatives. Now moving below the operating line. Net interest and other expense in Q1 was $7.4 million, similar to the amount in the same quarter of the prior year. Our effective tax rate under GAAP was 19.9% in Q1 of Fiscal 2026 versus 21.9% in Q1 of last year.
Excluding discrete tax items, our normalized effective tax rate, which is used in calculating non-GAAP EPS, was approximately 23.3% this quarter compared to 24.0% in the prior year quarter. On a non-GAAP basis, our Q1 Fiscal 2026 adjusted operating margin of 10.3% was consistent with that of the same quarter last year. The Security division's adjusted operating margin was 13.5% in Q1 compared to 14.4% a year ago. Strong growth in high-margin security service revenues was offset by a less favorable mix of product sales and growth in R&D. While Optoelectronics' adjusted operating margin of 11.9% was similar to the 12.0% in last year's Q1, we anticipate efficiencies in our newest manufacturing facility to contribute to expanding margins in the second half of the fiscal year. Lastly, the adjusted operating margin of our Healthcare division improved 260 basis points, driven in part by revenue growth.
Moving to cash flow and the balance sheet, our year-over-year operating cash flow improved in Q1. That being said, there was opportunity for it to be notably larger. We received partial payments from a significant Security division customer in Mexico during the quarter, marking encouraging progress. We continue to expect substantial cash inflows in Fiscal 2026 as we continue to collect those remaining receivables, which should lead to sizable operating cash flow this fiscal year and very strong free cash flow conversion. CapEx in the 2026 first fiscal quarter was $7 million, while depreciation and amortization expense was $10.3 million. Our balance sheet remains solid. At the end of the quarter, our net leverage was approximately 1.9, as calculated under our credit agreement. We amended our credit facility during Q1 to, among other things, extend the maturity date to July 2030 and increase the borrowing capacity to $825 million.
This expanded facility increases our liquidity and financial flexibility. Now turning to our updated guidance, we are raising our Fiscal 2026 guidance for both revenues and adjusted earnings per share. We now anticipate year-over-year revenue of $1.825 billion to $1.867 billion, representing a growth rate of 6.5% to 9.0%, up from the previous growth rate range of 5.4% to 8%. This updated outlook factors in an approximate 60% headwind from a reduction of revenues from our Mexico contracts in Fiscal 2026 in our Security division. We are also raising our non-GAAP adjusted earnings per diluted share guidance from a range of $10.11 to $10.39. To a range of $10.20 to $10.48, which represents 9% to 12% year-over-year growth.
We note that this Fiscal 2026 non-GAAP diluted EPS guidance excludes any impact of potential impairment, restructuring, and other charges, amortization of acquired intangible assets and their associated tax effects, and 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 backlogged revenues, new bookings, timing of cash collections, tariffs, and the government shutdown, among other factors, 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. In summary, we are committed to operational excellence as we continue to grow our businesses and provide innovative products and solutions to our customers.
We are excited about the solid start to Fiscal 2026 and anticipate building momentum throughout the year. We expect to generate strong cash flow and have the financial strength to invest in key strategic areas that will drive long-term value for our shareholders. Once again, and as Ajay mentioned, we thank the entire global OSI Systems team for their dedication to supporting our customers and partners. Their efforts are what make these results possible. At this time, we'd like to open the call to questions. Thank you, ladies and gentlemen. If you have a question or a comment at this time, please press Star 11 on your telephone. If your question has been answered or you wish to remove yourself from the queue, please press Star 11 again. We'll pause for a moment while we compile our Q&A roster. Our first question comes from Josh Nicholas with B. Riley Securities.
Your line is open. Yeah, thanks for taking my question. Good to see the guidance bump. I know Fiscal 1Q is usually a little bit slower for the Security division, but bucking the trend with a healthy book-to-bill ratio. I was wondering, could you provide just a little bit more granularity on what products and markets or geographies are really driving that strength, particularly since 1Q is usually a little bit slower, particularly in Europe? Oh, sure, Josh. Great questions. Thank you. Yeah, we are really pleased with the performance in our Security division, both on the revenue side and the booking side and operational as well. We really saw really quite diversified broad growth. We saw both on the revenues and the booking side throughout the regions when we were looking at the EMEA region, looking at the Americas, and even Asian PAC.
Strength, whether it be in revenues or bookings across the board. Service revenues, of course, were exceptionally strong for us. It's nice we're receiving this new era of much higher recurring revenues at higher margin on the service side. We had the contribution for a full quarter worth of the RF detection products versus a partial quarter in the prior fiscal year. We saw our aviation products doing quite well as well. All that contributed to really a great quarter for the Security division. Thanks. Just one follow-up question. You mentioned that you now had several quarters, right? The services revenue growth north of 20% here. Again, when you look at the top-line guidance for this year, you're guided to around 8% growth. I would assume that the services revenue growth would be significantly higher than that.
Any kind of additional detail you can provide around that to help us kind of model the growth rate that you may be expecting for that piece of the business this year? Yeah, Josh, when it comes to our guidance, you're correct. Though we don't provide guidance on service versus product specifically, directionally, you're absolutely right. We're expecting faster growth in our recurring service revenue in this particular year. Product revenues will be quite strong as well. Remember, we're coming off of a very difficult comp with heavy Mexico product revenues in Fiscal 2025. We expect to see very solid revenue growth both on product and service, but at a more accelerated rate on the service side in this fiscal year. Thanks. Just last follow-up for me, then I'll pass the torch since you mentioned it. Tough comp for Mexico, but the business is still growing very healthy.
Just thinking about longer term, and next year, the comps are going to get easier against Mexico. I think you might have mentioned it before, but revenue contribution for this year for Mexico, should that be around the $100 million type level, or what are you targeting for this year? That's a good estimate. Probably just slightly below that. Appreciate it. Thanks. One moment for our next question. Our next question comes from Jeff Martin with ROTH Capital Partners. Your line is open. Great. Thanks. Good afternoon. Great to see the results. Congratulations. Wondered if you could follow up with additional detail on your comment about governments worldwide are investing heavily. Has that been in your sights for quite some time now? I know you've talked about a robust and expanding pipeline for quite a while, but is this a newer phenomenon?
Because I don't think you've really phrased it that way in the past. I think this is Ajay. We've seen the growth in the past, but we definitely see a lot more acceleration going on. I think with the One Big Beautiful Bill we've all talked about, with the opportunities and the Golden Dome, I think our service business has accelerated. Not just on the service side, but we're able to go in and offer what I would say are integration services with our search scan that we just announced with CBP. We're in almost 20 different countries, and we see the capabilities there, and the government sees the capabilities not just of integrating the NII platforms, but integrating various different technologies and turning that data into real information. Frankly, with all the trade issues going on, they're able to integrate that, if they want, with U.S.
CBP, with their data coming through and making them a lot more efficient, making the tariffs less painful in terms of declarations. Obviously, the rest of it, as far as security is concerned, the geopolitical environment with Ukraine, Gaza, others continues to provide us opportunities. Yes, we think that there's uptake, but we feel very good about it in terms of what opportunities there are, not just in the U.S., but internationally. Great. Nice to see the uptick in the guidance, even in light of the federal government shutdown here. I was wondering if you could touch on what you're seeing to date in terms of affected activities from the government shutdown. From our standpoint, we've had very limited impact. I mean, we are in industries such as with CBP, others where it's considered essential. We have to provide our systems, our service, keep the borders, the airports open.
I think one of the things, maybe things get delayed a little bit in terms of some of the orders coming in, but really, it's not going to affect us in 2026. From our standpoint, so far, so good. It's really not a big deal. Okay. I have two clarifications, if I could. The reference to the 26% growth, excluding acquisitions in Mexico, that was to total company revenue. On the security side, it was 39%. Did I hear those correctly? Jeff, this is Alan. Yes, you've interpreted it exactly right. Okay. You said there's a headwind of 60% for Mexico. I assume you mean $60 million. Year-over-year? Effectively, a 60% reduction in revenues of Mexico revenues in Fiscal 2025 versus Fiscal 2026. Got it.
I think just to comment on that, I would look at that as a positive because we've been more than able to cover those headwinds with the tailwinds we've gotten the rest of the product lines. Great. Thank you. One moment for our next question. Our next question comes from Mariana Perez Mora with BofA Securities. Your line is open. Good afternoon, gentlemen. Hello. My first question is on Mexico. You mentioned some partial payments and improvement there and also a significant reduction on the revenue side. How should we think about the level of unbilled receivables so far, and how are those unbilled receivables progressing? What are the key milestones we should be looking at when we think about the timing of those payments along the next nine months of the fiscal year? Hi, Mariana. Good question. Really, some good progress on the unbilled receivables.
We've seen the unbilled receivables in Mexico at September 30th come down nicely from June 30th, and we expect to see that continued progress throughout the fiscal year. The nice part is, of course, as it moves from unbilled into billed, we can then start collecting the cash. As we look at Fiscal 2026, we expect some very significant cash flow from Mexico specifically, but from overall business more generally as well, which will lead to very strong free cash flow conversion. Thank you. When you think about free cash flow and the position you'll have, you'll have a lot of, I don't know, a deeper pocket to pursue different capital deployment activities. How is the M&A pipeline? What are you looking at when you look at that, especially after the RF detection products line is being performing so strongly?
How is that pipeline, and what type of capabilities are you looking at? This is Ajay. We're always looking at expanding. Our capabilities, not just on the recurring revenue service side, but also on the technology side, complementary technologies that can get us deeper into the government and other customers where we were offering them certain products. Now we can offer them and all of a sudden that's a solution. We're playing at a bigger pond as we go forward. Obviously, I've said this before, that any acquisition that we look at is going to be carefully looked at. We're going to see does one plus one equal three or four. Obviously, the rest of it to pay any cash we collect to pay down debt, obviously look at stock buybacks. We're looking at all three.
The good news is that we're in a very good position to evaluate what we want to do and look at the right acquisitions as they become available. Thank you so much. Last one from me on the government shutdown. Are you waiting for any meaningful awards that have been delayed by this extended government shutdown? How do you think about the risk as you think about the rest of the year from that? I think that we're working with the agencies during the government shutdown. Like I mentioned in my remarks, we're not as concerned about 2026. Really, some of the orders we're looking at are for beyond 2026. You might have a little bit of delay here or there, but it's more in getting some orders in. It's really nothing significant that should affect our fiscal year. Thank you so much. One moment for our next question.
Our next question comes from Seth Lichten with JPMorgan Chase & Co. Your line is open. Thanks very much, and good afternoon. Hi, Seth. Hey. Hi. Wanted to ask about the profitability, especially in security, since some of the mixed items you talked about offset the increase in the services mix, and so margin was down year on year. At what point do you see margin being able to expand again in the security business and kind of reset itself as the Mexico revenue kind of gets to a level where it's stable? Yeah, Seth, this is Alan. Good question. Really, the final quarter of the difficult Mexico comps when it comes to a margin perspective, particularly, is this upcoming quarter, the December quarter, which is, of course, built into our guidance and much more akin to what we've been seeing in the last couple of quarters.
As we get past the end of this calendar year and move into January, the comps get much more normalized from a Mexico perspective. We believe that there's ample opportunity to start showing margin expansion again. There will be quarters where it's very robust and quarters where there might be a different mix going the opposite direction as well. Really, as we move into the next calendar year and beyond, we should be in good shape to start focused on margin expansion again. Excellent. One follow-up, I guess, on the funding that's in the reconciliation bill. One of the things we've noticed on the defense side is that money has been a little bit slow in flowing out.
Some of that at this point might have to do with the shutdown, but even just because it comes out of the reconciliation process and tapping into it might be a little bit different for the customers. I was just wondering what your experience has been thus far in terms of discussions about those contracts. This is Ajay. I think I mentioned this last time as well. We're expecting that funding to come in probably towards the second half of our fiscal year, and we're still expecting that. On the other side, could it have come in maybe in December? Maybe. From our standpoint, that's when we're expecting, that's when we're planning on it. As far as the funding itself, you got to look at it. It's a big bill and there are priorities.
I think from our standpoint, one of the biggest priorities is really border funding, and we think that's not going to get delayed. I think that's going to come in as we expect it to come in. Anything can happen, but we feel very good about it right now. That's kind of the best way to look at it. Excellent. Thanks very much. Again, ladies and gentlemen, if you have a question or a comment at this time, please press star one-one on your telephone. One moment for our next question. Our next question comes from Lawrence Scott Solow with CJS Securities. Your line is open. Great. Thanks, and good afternoon. Good evening. Just a couple of follow-ups. Most of my questions have been answered. Can you just give us the specific number that the RF detection products business contributed in the quarter?
I think it was $17 million last Q1 last year on a partial. If you can give us that number. From a higher level, just thoughts on the Golden Dome initiatives. Just timeline from a higher level, not specific, but when we might see that. Is that quarters or is that years away? How big of an opportunity could it potentially be for this business? Larry, I'll take the first part of the question, and I think Ajay the second part. In terms of the RF, we bought that business in September of 2024, so we had three or four weeks of operations last year. Last year, we did about $4 million in revenues from that business. This past quarter, we did about $19 million of revenues.
It is, generally speaking, a little bit of a seasonally slower quarter, and we expect that to pick up over the balance of the year. The question on the Golden Dome. Obviously, with our RF technologies, especially in this case, over the Horizon radar, we feel that we're well positioned. Everybody's talking about the program being in the billions and billions or tens of billions of dollars. We think we have a pie in there. What it's going to be and how it's going to come across because it's not just the prevention, but it's obviously looking at missiles and other things. I think we'll know in the next two, three quarters, like I said before, but we feel good about where we are in the process. Great. Question just on the gross margin, Alan, and security.
I know you mentioned, obviously, product mix moves around a lot, but this quarter, gross margin on the products was significantly lower than I've seen it going back several years. Was there anything unusual beyond just the mix? Was it just a really lower margin mix this quarter? It really did come down to just being a lower margin mix this quarter on the product side, not necessarily reflective of what we would anticipate going forward. It just happened to be the mix of product sales in this particular quarter. The nice part was we made it up on volume to still have very, very nice profitability, but we would expect that product margin to be better in the future. Lastly, on the cash flow, the free cash flow, I know you get this question a lot, but it sounds like you remain confident in a good year.
My question would be, Mexico's kind of been the biggest impact. Now that your revenues from Mexico are very modest, as we look out of the next few quarters, assuming even if they're a little bit late, I got to imagine by the end of this year, a lot of that hopefully Mexico delayed payment and AR specifically should come down a lot, almost normalize. Is it possible that we have a free cash flow. Drop through conversion rate close to net income this year? Thanks. Good question. Yes. We would expect the Mexico cash flows to be very strong over the next few quarters and will position us extremely well. In terms of looking at free cash flow to net income, I think you're right. You might even be conservative. I believe we can exceed 100% of net income and possibly by a significant amount.
It could be a very, very nice free cash flow year for us. All right. Thanks. I appreciate it. I'm not showing any further questions at this time. I'd like to turn the call back to Ajay for any further comments. I want to thank those in attendance for joining our call. We're excited about the opportunities ahead and look forward to speaking with all of you at our next call. Thank you very much. Ladies and gentlemen, this does conclude today's presentation. You may now disconnect and have a wonderful day.
