OSI Systems (OSIS) 2026财年第四季度业绩电话会议：5000万美元交付延迟及2027财年业绩指引

核心要点

• 2026财年第四季度营收同比下降约4%至4.84亿美元，主要是由于中东地区发生冲突导致延误及现场进入受限，原计划中价值约5000万美元的安防部门交付项目推迟至6月30日之后。公司表示，这些交付项目仍留在积压订单中，并未丢失。
• 全年营收增长4%，达到创纪录的17.9亿美元；非GAAP摊薄每股收益（EPS）增长11%，达到创纪录的10.35美元。第四季度非GAAP每股收益增长17%至3.78美元。
• 第四季度调整后营业利润率扩大200个基点至17.7%。三大业务部门均有所改善，其中医疗保健部门的调整后营业利润率从1%升至10%。
• OSI Systems在2026财年结束时拥有创纪录的约19亿美元积压订单。全年订单出货比略高于1，而第四季度订单出货比略低于1。
• 管理层预计2027财年营收为18.75亿至19.3亿美元，调整后每股收益为11.13至11.49美元。预计下半财年增长最为强劲。
• 经营活动现金流在第四季度达到创纪录的1.82亿美元，全年达到2.76亿美元。管理层预计2027财年自由现金流将超过净利润的100%。

关键财务数据

OSI Systems在第四季度从其墨西哥最大的客户处收回了1.59亿美元。该客户的应收账款余额从第三季度末的3.45亿美元（占总应收账款的40%）降至财年末的1.90亿美元（占25%）。管理层预计该余额将在2027财年显著下降。

公司在第四季度以约219美元的均价回购了约56.5万股股票，总计1.236亿美元。2026财年期间，公司累计回购并注销了110万股股票。在新获得授权后，目前仍有约110万股可用于回购。

业务与运营业绩

安防部门

安防部门第四季度营收下降7%。这一降幅反映了中东交付推迟，以及上年同期墨西哥项目营收基数较高带来的高基数影响。2026财年与墨西哥安防合同相关的营收较上年减少了近1.5亿美元，其中第四季度面临约2000万美元的逆风。

公司预计与墨西哥相关的营收逆风将在2027财年放缓至不到2500万美元，且主要集中在上半财年。扣除上年同期的墨西哥安装营收后，第四季度安防服务营收同比增长9%。管理层预计2027财年总服务营收将实现强劲的双位数增长。

随着美国国土安全部于4月重新开放，采购活动有所加速。美国海关和边境保护局（CBP）授予OSI Systems两份为期五年、独家中标的IDIQ（不确定交付日期/不确定交付数量）合同：其中一份上限约为2亿美元，用于可移动快速扫描乘用车检查系统；另一份上限约为8500万美元，用于厢式车载移动X光检查系统。

公司已收到这两份合同项下的交付订单，包括一份价值约2100万美元的任务订单。管理层预计其对2027财年的贡献有限，而在2028财年及以后将带来大幅增加的营收。IDIQ合同的最高限额不被计入积压订单；只有在确定授予具体的交付订单或任务订单时才会计入积压订单。

OSI Systems还签署了一项协议，使Rapiscan成为美国国家队（Team USA）的官方支持者，以及2028年洛杉矶奥运会和残奥会的安检与安全技术硬件及软件供应商。

射频与国防项目

管理层表示，整个射频（RF）产品组合的客户参与度达到了该产品线有史以来的最高水平。在2026财年期间，OSI Systems获得了一项未定价合同动作（UCA），最高金额不超过约2.35亿美元，用于国土防空超视距雷达发射子系统。该项目约80%的金额已在第三财季计入积压订单，其中很大一部分计划在未来几年内交付。

公司还参与了支持“铁穹”（Iron Dome）相关项目的SHIELD IDIQ合同。管理层预计射频业务在2027财年将实现强劲增长，并在2028财年保持持续增长。

光电子与制造部门

光电子与制造部门全年营收增长9%至4.51亿美元。在规模效应和更为有利的营收结构支撑下，第四季度调整后营业利润率从13.6%升至14.7%。

管理层预计2027财年的营收增长将伴随着营业利润率的进一步扩大，不过季度业绩可能会随客户和产品组合的变化而有所波动。

医疗保健部门

医疗保健部门第四季度营收同比增长约5%。调整后营业利润率从1%提升至10%，反映出出货量增加、经营杠杆效应以及年内实施的运营改善措施。管理层提醒不要将单一季度的利润率表现进行外推。

管理层业绩指引

管理层表示，该展望对中东地区的交付时间节点和未来区域新签订单采用了较为保守的预估。在延期的约5000万美元交付项目中，很大一部分预计将在2027财年下半年完成，但并非全部。

指引中仅包含了已收到的CBP交付订单的一部分，而非总计2.85亿美元的IDIQ最高限额。管理层预计，近期在美国获得的项目将在2028财年、2029财年及以后做出更大的贡献。

OSI Systems计划加大对基础设施和产品创新等特定运营领域的投资。其长期目标是将营收增长与营业利润率扩大结合起来，部分得益于高利润率服务营收的更快增长。

风险与关注要点

• 中东地区的冲突和现场进入受限导致交付及近期新签订单推迟。未来时间节点的进一步变动可能会影响积压订单的转化和营收的分阶段确认。
• 预计2027财年的增长将集中在下半年，从而增加了对交付时间表的敏感性。
• 巨大的IDIQ合同最高限额不会自动计入积压订单或营收；转化为实际收入取决于未来的任务订单和交付订单。
• 管理层将关税、供应链中断、外汇波动、产品与服务组合、回款时间点以及地区冲突列为不确定性来源。
• 2027财年每股收益指引扣除了潜在的减值、重组及其他成本、收购无形资产摊销、相关税务影响以及离散或非经常性项目。

分析师问答要点

• 现金转化：管理层预计2027财年的现金生成能力强劲，并表示自由现金流可能会超过净利润的100%。预计全年均有回款，且倾向于呈现前置形态。
• 中东时间节点：大多数推迟的交付项目均针对中东客户。在保持保守假设的前提下，管理层预计很大一部分将在2027财年下半年完成。
• 积压订单机制：2.35亿美元的射频项目中有约80%已在第三财季计入积压订单。对于CBP的IDIQ合同，仅有确定的任务订单或交付订单会被纳入积压订单，而非全部最高限额。
• 服务营收：增长预期来源于墨西哥系统走出保修期、货物、车辆及检查站产品的安装基数扩大、射频支持、安全即服务（security-as-a-service）产品以及TruSaaS软件服务。
• 安防利润率：随着时间的推移，管理层预计服务营收的增速将快于产品营收。由于服务营收具有更高的利润率，服务业务占比提升可能会支持安防部门在2027财年之后进一步扩大利润率。
• TSA机遇：管理层表示，由于美国运输安全管理局（TSA）优先发展安检口系统，TSA托运行李扫描仪的商机距离现在还有数年之久，但该项目最终可能会延续多年。

管理层陈述

Operator

Thank you for standing by and welcome to the OSI Systems, Inc.'s fourth quarter 2026 conference call. [Operator Instructions] As a reminder, today's program is being recorded. And now I'd like to introduce your host for today's program, Alan Edrick, Chief Financial Officer. Please go ahead, sir.

Alan Edrick

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 of Security. Welcome to the OSI Systems Fiscal 2026 Fourth Quarter and Year-End Conference Call. We're pleased that you can join us as we review our financial and our operational results.

I'd 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. 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, new information, or otherwise. We will also reference both GAAP and non-GAAP financial measures. Applicable reconciliations are available in today's earnings release.

I will begin with a high-level summary of our financial performance for the fourth quarter and the full fiscal year, 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 our outlook for fiscal '27. Before I discuss our fourth quarter records, let me address the revenue results. Full-year revenues of $1.79 billion finished below our guidance range, and fourth quarter revenues of $484 million were down approximately 4% year-over-year.

Importantly, these results were affected by the timing of approximately $50 million of planned security deliveries that moved beyond our June 30th fiscal year-end because of conflict-related delays and site access constraints in the Middle East. I want to emphasize that these expected revenues are deferred, not orders lost. They remain firmly in our backlog and are expected to be delivered on a later schedule.

Setting this aside, we were really pleased with the overall performance as multiple key performance metrics for Q4 and the full fiscal year were extremely strong. We closed fiscal '26 with exceptional cash generation and strong profitability driven by solid adjusted operating margin expansion. We delivered record fourth quarter operating cash flow of $182 million. We grew fourth quarter non-GAAP earnings per share by 17% to a record $3.78. And we ended the year with a record backlog of approximately $1.9 billion.

For the full year, revenues reached a record $1.79 billion, up 4% year-over-year, and adjusted earnings per share grew to a record $10.35, up 11% year-over-year. Bookings were solid across the three divisions, and we finished the year with a record backlog and solid visibility as we enter fiscal '27. We also have a significant opportunity pipeline, and we have recently secured several important program wins.

Our cash conversion was outstanding, allowing us to strengthen the balance sheet while continuing to return capital to shareholders. In the fourth quarter, we repurchased approximately 565,000 shares at an average price of about $219 per share for a total of $123.6 million. Our board recently authorized an additional 1 million shares, leaving approximately 1.1 million shares available under our stock buyback program. Before diving more deeply into our financial results and discussing our outlook for fiscal '27, I'll turn the call over to Ajay.

Ajay Mehra

Thank you, Alan, and thank you to everyone for joining us today. I am pleased to be here to discuss our fourth quarter and full fiscal year 2026 results. Fiscal 2026 was a strong year for OSI Systems, capped by record annual revenues of $1.79 billion, record Q4 and annual non-GAAP earnings per share, and record Q4 and annual operating cash flow. That said, as Alan pointed out as well, we finished 2026 with revenues below expectations, mostly due to delays with the situation in the Middle East.

Overall, I am proud of how our team has performed across the portfolio, delivering solid bookings that translated into a record backlog of approximately $1.9 billion, which gives us good visibility as we enter fiscal 2027. While the Security division faced revenue headwinds in the quarter from the Middle East conflicts that have shifted the timing of certain deliveries, Optoelectronics delivered strong growth on broad-based demand, and Healthcare posted an improved quarter. The security-related deliveries that were pushed out remain in backlog and are expected to be completed in future orders.

So let's discuss our business in more detail, beginning with Security. With DHS reopening in April, following the shutdown, we have seen procurement activity accelerate. Since the close of our fiscal year, CBP has awarded us two 5-year IDIQ contracts, one with a ceiling of approximately $200 million for relocatable rapid scan passenger vehicle inspection systems, and a second with a ceiling of roughly $85 million for van-mounted mobile X-ray inspection systems.

We have already received delivery orders under both these IDIQs, including a task order valued at about $21 million. These IDIQs represent continued funding provided under the omnibus bill. We expect to see some revenue contribution from these awards later in fiscal 2027, but significant contributions are expected in fiscal 2028 and beyond as well. We have also made growing recurring revenue a priority across the Security division, and with the size of our installed base today, we expect that effort to translate into substantial service revenue growth in fiscal 2027.

Recently, we entered into an agreement with LA28 to establish Rapiscan as an official supporter of Team USA and the official physical screening and security technology hardware and software solutions provider of the LA28 Olympic and Paralympic Games. This strategic partnership builds upon our security efforts at major recent events such as the FIFA World Cup, the Paris Olympics, and the Milan Winter Games. Few companies have a comparable track record at this scale, and our experience is a real advantage as we pursue future large venue and event security opportunities.

We continue to see strong momentum in our radio frequency, also known as RF business, and Homeland Security Defense business. Our over-the-horizon radar programs and involvement in multiple Iron Dome initiatives position us at the forefront of some of the nation's most significant defense priorities. Fiscal 2026 was an outstanding year for the RF business. During fiscal '26, we were awarded an undefinitized contract action with a not-to-exceed value of approximately $235 million for the production and integration of a homeland defense over-the-horizon radar transmit subsystems.

RF award today, and we continue to see follow-on opportunities related to this program. We are also a participant in the SHIELD IDIQ, which supports much of the Iron Dome-related initiatives and gives us a vehicle to pursue additional programs as they're defined over the next few years. All that said, the current level of customer engagement across our RF portfolio is the highest we have seen for this product line.

Turning to Optoelectronics and Manufacturing, which delivered another strong performance in fiscal 2026 as full-year revenues grew 9% to $451 million with strong margins. The bookings in Q4 reflected the strength and breadth of our entities' markets, and we expect these underlying trends to continue in fiscal 2027. Our ability to support customers with our highly engineered products, precision manufacturing, and global reach continues to differentiate us across the aerospace, defense, healthcare, and industrial customer base.

Our vertically integrated model and global manufacturing footprint helps us continue to capture business as customers diversify supply chains, and our backlog gives us strong visibility heading into fiscal 2027. Finally, our Healthcare division delivered an improved fourth quarter as revenues grew approximately 5% year-over-year and operating margin expanded to 10% from 1% compared to last year's Q4. These results reflected the operational improvements we've been implementing throughout the year.

We remain focused on expanding our installed base, supporting providers with innovative clinical solutions, and advancing the product development initiatives behind our next-generation patient monitoring platform. We are encouraged by the opportunities ahead. As we enter fiscal 2027, our record backlog, robust pipeline, and disciplined execution give us confidence for the coming years. As always, I would like to thank our employees, customers, and stockholders for their continued support and dedication. With that, I will turn the call over to Alan to discuss our financial results and our fiscal 2027 guidance in more detail before we open the call for questions. Thank you.

Alan Edrick

Thank you, Ajay. Let's begin with our revenue performance by division. Revenues in each of our Opto and Healthcare divisions increased 5% year-over-year. In Security, revenues declined 7%, reflecting the impact of the conflict in the Middle East, which delayed certain deliveries beyond our fiscal year-end, along with a difficult comparison against higher Mexico program revenues in the prior year quarter. We closed the year with approximately $1.9 billion in backlog. Deliveries that shifted out of the quarter remained in backlog, while certain expected bookings in the affected region were deferred.

As expected, we reported nearly $150 million lower fiscal '26 revenues related to the Mexico security contracts compared to the prior year, which included about a $20 million adverse impact in Q4. As we move into fiscal '27, we expect this headwind to moderate to less than $25 million for the full year, which is expected to be concentrated in the first half. Turning to services. For the full year, service revenues grew 13% to $441 million, though were fairly flat in Q4. Similar to Q3, fourth quarter service revenues in the prior year benefited from significant installation activity related to the Mexico contracts.

Excluding those installation revenues, security service revenues increased 9% year-over-year in Q4. Looking forward, in fiscal '27, we expect strong double-digit growth in service revenues for the full year. Our Q4 fiscal '26 gross margin expanded to 34.7% from 33.3% in the same quarter in the prior year, as a more favorable revenue mix on product sales more than offset the benefit in Q4 of the prior year received from higher installation-related service revenue. Our margins can fluctuate based on product and service mix and volume, supply chain costs, foreign exchange, tariffs, and other factors.

Moving on to operating expenses. We continue to work diligently across all divisions to manage our SG&A cost structure efficiently. SG&A expenses in the 2026 Q4 were $70 million, down 7% from the prior year Q4, representing 14.4% of sales compared to 14.8% of sales in the prior year. R&D expenses in Q4 were $19.5 million, or 4% of revenues, up from $18.8 million, or 3.7% of revenues in the same quarter last year. This increase stems from our commitment to investing in innovation, resulting in market-leading offerings, and positioning OSI well for the future.

We expect to continue our heightened R&D efforts to advance key initiatives. Even with these R&D investments, our combined SG&A and R&D expenses as a percentage of sales have decreased annually for each of the past 8 years, underscoring our ability to drive operating efficiencies while still funding growth initiatives. Now let's move below the operating line. Net interest and other expenses in Q4 were $4.1 million, down from $7.2 million in the same quarter of the prior year, primarily due to reduced borrowing costs coupled with increased interest income on higher cash balances.

Our effective tax rate under GAAP was 20.8% in Q4 of '26 versus 19.8% in Q4 last year. Excluding discrete tax items, our normalized effective tax rate, which is the one used in calculating non-GAAP EPS, was 21.5% in Q4 compared to 21.9% in the same prior year quarter. On a non-GAAP basis, our Q4 '26 adjusted operating margin was 17.7%, up 200 basis points from the 15.7% reported in the prior year fourth fiscal quarter, with each of the three divisions reporting growth.

The Security division's adjusted operating margin expanded from 20.4% to 20.8% in Q4 this year, driven by a stronger gross margin combined with reduced operating expenses. The Opto adjusted operating margin increased to 14.7% in Q4 of '26 from 13.6% in last year's fiscal Q4, primarily from the benefits of economies of scale and a more favorable mix of revenues. And on the heels of stronger revenues, the adjusted operating margin of our Healthcare division, as Ajay said, increased to 10% in Q4 this year, from 1% in Q4 of the last fiscal year, reflecting the operating leverage. And while we would not extrapolate one quarter, it shows what this division can do as volume grows.

Moving to cash flow and the balance sheet. We generated a record $182 million of operating cash flow in Q4 and $276 million for the full fiscal year driven by strong collections across the businesses. This included collecting $159 million from our largest customer in Mexico in Q4. On that customer specifically, the balance stood at $345 million at the end of Q3, representing 40% of the company's total accounts receivable, and declined to $190 million, or 25% of the company's total AR, as of the end of Q4.

This balance should significantly decrease further throughout fiscal '27 as substantial payments are expected to be received, contributing to the strength in the anticipated fiscal '27 operating cash flow and free cash flow conversion. DSO in Q4 decreased 18% from third quarter DSO. CapEx in Q4 was $9.3 million, while depreciation and amortization expense in the quarter was $13.3 million. Our balance sheet remains solid, providing us great flexibility. We ended the year with $360 million in cash, up from $106 million a year ago, and with no amounts drawn under our lines of credit.

During the year, we refinanced our credit facility and extended its maturity while adding low-cost long-term debt. Gross debt increased with these moves, and with the capital we returned to shareholders, our net leverage at the end of Q4 of fiscal '26 was approximately 2.1x as calculated under our credit agreement. This leaves us ample capacity for both organic investment and acquisitions. During the fiscal year, we repurchased and retired 1.1 million shares, reflecting our conviction in the intrinsic value of our business. Our board recently authorized an additional 1 million shares for repurchase with no expiration on this authorization.

Now, turning to our guidance. We are introducing our fiscal '27 guidance for revenues and non-GAAP earnings per share. We currently expect revenues of $1.875 billion to $1.93 billion, or 5% to 8.1% year-over-year growth, and adjusted earnings per share of $11.13 to $11.49, or 7.5% to 11% year-over-year growth. This guidance factors in the expected impact from the conflicts in the Middle East, which have affected near-term bookings, though over a longer horizon the resolution of these matters could represent future opportunities for the company.

Although we are pleased with some notable wins with the Department of Homeland Security over the past few months and expect more, we believe a substantial amount of such bookings will lead to revenue in fiscal '28 and beyond. Thus, we have included a portion of the delivery orders from CBP already in hand rather than the full ceiling value of those programs and assumed a later delivery schedule in the Middle East. Given the timing of each of these items, we currently expect fiscal '27 growth to be strongest in the second half.

We note that our fiscal '27 non-GAAP diluted EPS guidance excludes any impact of potential impairment, restructuring and other costs, 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, the conflicts in the Middle East, and supply chain disruptions, 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, fiscal '26 was a year of record cash generation, record backlog, and strong earnings quality. We strengthened our liquidity, and we returned capital to shareholders. We are committed to operational excellence as we continue to grow our businesses and provide innovative products and solutions to our customers. We aim to invest in key strategic areas with the goal of driving long-term value for our shareholders. Once again, we thank the entire global OSI team for their dedication to supporting our customers and our partners. Their efforts are what makes these results possible. And at this time, we'd like to open the call to questions.

Operator

Our first question for today comes from the line of Josh Nichols from B. Riley Securities. Your question, please.

分析师问答

Josh Nichols

Understand the pushout, not lost orders regarding the Middle East, but I was curious on that. Do you expect that free cash flow generation in fiscal year '27 could similarly exceed net income generally, and how you think about the pace of collections is going to drive that this year?

Alan Edrick

Josh, thank you. This is Alan. Good question. We are anticipating a strong cash flow year in fiscal '27, strong free cash flow, and we do anticipate that our free cash flow could exceed 100% of net income and fully expect that to occur. With respect to the pace of collections, we expect to be collecting nicely over the course of the fiscal year, hoping it's more front-loaded than back-loaded, but we do anticipate a good, strong overall year.

Josh Nichols

I think the timing, it's understandable for some of the orders in the Middle East, but there's been a flurry of award activity just over the last couple weeks. I'm curious, how much of that, are you being conservative when you think about how much of that gets factored into the guidance for this fiscal year, given the ongoing conflict? And are you assuming most of that gets pushed out to fiscal year '28 and beyond? I'm just trying to get a little bit better grasp on how you're thinking about these newer awards and IDIQs and the timing in your guidance for this year.

Ajay Mehra

So, this is Ajay. You know, like we pointed out, there's a portion in '27, but the vast majority is in '28 and beyond. You know, these are multiple-year IDIQs. I do want to point out both the $200 million and the $85 million IDIQ with CBP, we're the only awardee on there. So, it gives us a very good confidence that as we look at not just '27, but '28, '29, and beyond, the visibility really is there for us.

Josh Nichols

Thanks for clarifying. I'll hop back into queue.

Operator

Our next question comes from the line of [ Don Gooden ] from Citigroup. Your question, please.

Unknown Analyst

You know, obviously it's a complex situation in the Middle East. I was hoping to revisit, just maybe offer a little more detail on kind of what's going on there from your perspective on the ground, just to kind of give us a better feel for things. And in the release, you used the phrase that demand for products and services remains encouraging. In the prepared remarks, I felt like you used the word strong a few different times when talking about the shape of the business. I'm not trying to wordsmith this, but maybe just revisiting the Middle East and exactly how you see the demand today, a bit of a temperature check would be helpful.

Ajay Mehra

Sure. I think when we talk about strong demand, you've got to look at the overall business, the Security, the Opto, and even the improvements we've had on the Healthcare side. But specifically on Security, we have a lot of strong demand. Finally, like I pointed out, DHS, it's time to release orders. It's been a flurry of activity. We've also had some strong orders, like we pointed out, on the RF side. And international orders continue to be strong.

Now, specifically on the Middle East, yes, I think there's been a delay, deferment of some orders. You know, they're more interested in making sure they protect their people with incoming missiles, et cetera. And we are a partner, we work with them, make sure that whatever they need in the short run, we provide. But we believe in the long run, it's actually an opportunity for us, not just for the Middle East, but really with the DOD and other places where force protection is going to get more and more important, not just our overall security business and perhaps even including RF. So it's a complicated situation, but you know we've got to look at it as an overall business in the entire world, and we remain very confident there.

Unknown Analyst

Got it. That's helpful. And for the RF product line, I think you used the phrase that customer engagement was the highest you've ever seen, and certainly understandable given everything we're seeing in the defense complex and Iron Dome, et cetera. But I was hoping you could talk a little bit more about that and how are you kind of baking in the outlook for RF in the guidance for '27 and might it continue to grow in '28 as well?

Ajay Mehra

So, you know, we don't really break it down, but I will say on the RF side, we see very strong growth, and we see that growth continue into '28. And I think, you know, you talk about the conflict in the Middle East. If anything, what's been going on there, when you talk about the Iron Dome, it only further strengthens the idea of why we need an Iron Dome going forward.

Unknown Analyst

Got it. Appreciate the color.

Operator

Our next question comes from the line of Jeff Martin from Roth Capital Partners. Your question, please.

Jeff Martin

Just was curious if you could clarify whether these were deliveries to customers in the Middle East or whether there were shipments going through the strait that perhaps were intended for non-Middle Eastern customers of other nations that were also impacted.

Alan Edrick

These were mostly, if not all, customers in the Middle East.

Jeff Martin

Okay. And then in terms of what you were assuming in your updated fiscal '26 guidance after the third quarter, were you assuming that all of these orders would be delivered in Q4 or was the assumption that some of them would be and some of them would be pushed out further?

Alan Edrick

Jeff, this is Alan. So following the Q3 release, we assumed a significant portion of these Middle East orders would be delivered in Q4. Not all of them, but a significant portion.

Jeff Martin

Okay. And it sounds like your assumption is that a good portion of these will be delivered in the second half of fiscal '27. Is that fair to say?

Alan Edrick

That is fair to say. Not all of it, but a substantial portion in the second half of fiscal '27.

Jeff Martin

Okay. And then my other question is on the bookings. Could you speak to book-to-bill for the full year and then also kind of give us a sense on Q4? I know there were delays that impacted bookings in the second half in general, but just some contextual reference would be helpful.

Alan Edrick

Sure, Jeff. So for Q4, our book-to-bill was just shy of 1. It was very strong in our Opto division, solid in our Security division as well, and Healthcare. So giving us a very good book-to-bill in our highest revenue quarter. And for the full year, our bookings were quite solid as well. So the book-to-bill was a little bit north of 1 for the full year, which led to our highest overall backlog at the end of June.

Operator

Our next question comes from the line of Christopher Glynn from Oppenheimer. Your question, please.

Christopher Glynn

Just want to talk a little bit about the mechanics of phasing from large project awards, IDIQ and RF into backlog. You know, it was clear that the recent $285 million were subsequent to the quarter end. And I think you talked about $21 million firm order plus others. Should we think about the delivery orders as what goes into backlog and then also, using that framework for the $235 million RF, I think most of that did go in backlog in the prior quarter. So, I guess the implication would be those delivery orders were more coincident with the award, if you could clarify those points.

Alan Edrick

Sure, Chris. Happy to do so. With respect to the RF order, the $235 million that you referred to that we won in Q3, roughly 80% of that was booked into backlog in the third quarter, meaning we have it and a substantial portion of that is going to get delivered over the next couple of years. With respect to the two large IDIQs that we just won with CBP, the $285 million that you referred to, those are ceiling values where we're the sole awardee, as Ajay mentioned. What goes into our backlog is not the IDIQ value, it would be the firm fixed order, the delivery order or the task order at $21 million that Ajay referred to. So over the course of time, we expect that to significantly increase and move into our backlog and then convert into revenue.

Christopher Glynn

Okay, great. And my understanding is historically that those ceilings have essentially been realized and well within the IDIQ timeframe. And in particular, the context here is there's a much bigger funding than these amounts. So they've got to get through executing these portions in order to further exercise through the overall funding, which I think approximates a billion. Is that about the right understanding?

Ajay Mehra

Yes, that's the right understanding. I mean, keep in mind, these are orders that are being released. There are more orders that will be released in different products as we move along as part of the billion-dollar funding. So these are specifically for the two types of systems that I pointed out in my prepared remarks.

Christopher Glynn

Okay, great. And last one was, wanted to ask about the Opto segment profitability approaching 15%. I know you've brought on some new capacity. You're continuously expanding that business given the share opportunity with customers securing their supply chains. So as you utilize new capacity, are we talking about consistently higher margin opportunities for the O&M than over the past few years?

Alan Edrick

Yes, Chris, this is Alan. Really good question. The Opto business has been bringing on a stronger customer profile that is leading to improved margins. Our plan for fiscal '27 is to continue to pair revenue growth with operating margin expansion. It will vary from quarter to quarter based upon the revenue mix that we see and what products and which customers we happen to be selling to in that quarter. But we do believe that we'll see further operating margin expansion through the course of fiscal '27.

Our next question comes from the line of Larry Solow from CJS Securities. Your question, please.

Lawrence Solow

I guess the first question, just better frame the outlook for revenue guidance. So it sounds like you are including most of that 50 to come in, but just how about qualitatively from the Middle East? Are you assuming that there's still impacts obviously going on there? So what are your high-level expectations for the Middle East and also what's incorporated in the growth outlook from the United States? Not specifically, but is there some delays? Bookings obviously were delayed a lot. It sounds like most of the benefits from the omnibus bill and the acceleration in the U.S. that everybody's looking for, you're not building most of that in until '28. Is that all fair to say?

Alan Edrick

Larry, I should probably flip-flop and call you Chris for the moment. Good questions, Larry. You know, so with respect to the Middle East, we've taken a conservative approach in our guidance for fiscal '27, both with the planned deliveries that got deferred out of Q4, as well as for future orders, for obvious reasons, while the conflict is taking place. With respect to the United States, the really exciting part for us is, yes, we're getting nice bookings. We expect to get significantly more bookings. And you're exactly right. There's a portion built into fiscal '27, but a smaller portion. The much, much larger portion is in fiscal '28, '29, and even beyond that. So it really gives us some excellent visibility into real nice growth beyond this fiscal year. So, quite exciting for us. Was there a third element to it, or did I capture that?

Lawrence Solow

I think you got it. I just, the question that, a couple of thoughts just on the omnibus bill, I think it was a well over $6 billion authorization. And obviously I think a billion of that was kind of in the heart of your non-intrusive equipment. But I know that the Secure America Act came out. I think there was another like $3 billion or a little more than that, maybe north of that. Any clarity on how much of that could be funneled down into your kind of sweet spots?

Ajay Mehra

So, you know, it's a great question. We're aware of it. We're working with the customer very closely. Obviously, they're trying to make sure that they award, with all the delays, they award the billion dollars at the fastest pace possible. I think there is still some clarity to be had with what the next 2 or 3 billion would be. And I would add on the omnibus bill, we talk about customs, but there's substantial funding for the RF side as well, which is obviously helping us as well.

Lawrence Solow

Okay, if I can just squeeze one more, just on the margins, you're forecasting 5% to 8.1% revenue growth and a little bit higher on the earnings, 7.5% to 11%, not much, but you're also getting a pretty good benefit from your repurchases, right? You cut down your share count by like 3%. So you're actually building in, adjusted-wise, a little bit less earnings growth versus sales growth. Am I missing something, any reason for that?

Alan Edrick

Yes, Larry, we're just being a little bit modest and conservative coming out of the gate here, doing a little bit more investments in some OpEx and positioning ourselves for the future as well and some of the new innovative products that are coming out and the associated infrastructure sort of associated with it. But that's the general tone of it.

Lawrence Solow

Okay. So there's no structural change or anything. I mean, Healthcare, which we've talked about, much smaller, and Opto, moderate size, but those, we've talked about margins going up in those segments over the next few years. Any reason to believe that Security shouldn't have upward trends in the margins as well, maybe not so much this year, but just in general?

Alan Edrick

Yes, that's our plan. Our plan is to pair the top-line growth with operating margin expansion. From a contract-to-contract basis that may change a little bit. So it may change things from a quarter to quarter, but over the long term structurally, our goal is to continue to improve our margins. We expect our service revenues to be growing at a faster clip than our product revenues, and our service revenues inherently carry a higher margin. So as we start to look out beyond '27, '28, '29, and '30, as service revenues become a bigger and bigger proportion of our overall revenues, that can really drive some nice operating margin expansion in Security as well.

Operator

As a reminder, ladies and gentlemen, if you do have a question at this time, please press star 11 on your telephone. Our next question comes from the line of Seth Seifman from J.P. Morgan. Your question, please.

Seth Seifman

This is Rocco on for Seth. On the prior comment on the services revenue growth, should we think about a driver of that growth being the transition of the work in Mexico towards services? And does the services revenue in Mexico carry a stronger margin relative to OSI's typical services revenue, kind of similar to the product revenue being a pretty strong margin?

Alan Edrick

Yes, Rocco, so nice questions. So our service revenues, the Mexico service revenues are more or less in line with overall service revenue margins, which are quite strong to begin with. So we're encouraged by that. In terms of the service revenue growth, what's driving it, it's kind of multifold. Part of it is the Mexico product revenue rolling off of warranty and more and more of that moving into service revenues. That helps. The larger installed base, though, that we have throughout our cargo and vehicle inspection products, throughout our aviation and checkpoint products, and even some of the RF products will all drive more service revenues with strong margins.

We're also looking at some of the SaaS-type work that we do for our security as a service, our turnkey products, and we think there's some good opportunities going forward there. And also our software as a service, our TruSaaS, for CertScan and otherwise, which carry substantial margins, and we see some nice growth opportunities there as well. So the top-line growth of service could be quite substantial for us at a much higher margin.

Seth Seifman

Great. That makes sense. And then kind of looking ahead, are there any updates on the TSA checked bag scanner contract that's expected in '27, and when should we start thinking about that kind of coming into focus?

Ajay Mehra

I think we're looking at it and TSA basically is trying to get their checkpoint taken care of first and we think it's still a few years away, but it'll go on for several years, so the opportunity definitely is still there.

This does conclude the question and answer session of today's program. I'd like to hand the program back to management for any further remarks.

Alan Edrick

Once again, thank you all for attending our conference call. We look forward to speaking with you during our next earnings call following the completion of our first fiscal quarter.
