Earnings Call Analysis

IS&S Reports Strong Q4 Growth with Strategic Focus on Military and Acquisitions

Innovative Solutions & Support (IS&S) showcased an impressive Q4, with revenues increasing 18% year-over-year to $15.4 million, bolstered by military contracts and recent Honeywell acquisitions. Net income reached $3.2 million, up from $2.6 million. However, gross margins are expected to trend towards the mid-50% range, impacted by higher military sales and increased amortization from acquisitions. The company anticipates consistent growth into 2025, with a focus on advanced avionics and a strategic capital allocation plan, including a $6 million facility expansion to double manufacturing capacity. Strong backlog over the next four years indicates sustained demand and operational leverage.

Strong Financial Performance and Revenue Growth

In the fourth quarter of fiscal 2024, Innovative Solutions & Support (IS&S) posted net revenues of $15.4 million, reflecting an 18% increase year-over-year. This growth was primarily attributed to the integration of recently acquired Honeywell product lines and momentum from new military contracts. Product sales amounted to $9.8 million, driven largely by the commercial air transport sector, while customer service revenue reached $5.5 million, reiterating the benefits of the Honeywell acquisitions.

Gross Profit and Margin Adjustments

The gross profit for the fourth quarter was reported at $8.5 million, an increase from $8.1 million in the previous year. However, the company anticipates a shift in gross margin dynamics due to increased depreciation from the acquisitions and a notable shift in sales mix toward military products, which typically yield lower margins. IS&S expects consolidated gross margins to normalize around the mid-50% range going forward, compared to historical levels. A focus on adjusted EBITDA margin will become a better measure of long-term performance.

Operating Leverage and Investment in Growth

Operating expenses showed a reduction with selling, general, and administrative costs dropping to $3.1 million from $6.8 million last year. This decrease was largely due to one-time expenses reflected in last year's figures. The R&D expenses saw an uptick to $1.1 million from $740,000, driven by expansion in product development initiatives. Moving into fiscal 2025, IS&S is set to increase manufacturing capacity by more than 100% through a $6 million facility expansion, critical for supporting higher sales volumes.

Guidance and Expectations for Future Growth

IS&S maintains an optimistic outlook for 2025, expecting similar revenue growth rates to 2024, fueled by military contracts and synergies from the Honeywell acquisitions. New orders in Q4 2024 totaled $95.4 million, contributing to a solid backlog of $89.2 million. IS&S anticipates significant contributions from military programs and projects that are likely to enhance profitability.

Strategic Focus on Military and Cross-Selling Opportunities

The company is strategically positioning itself in military markets, having expanded its footprint through acquisitions. The military segment is expected to grow significantly, fueled by contracts with the U.S. Department of Defense and allied foreign militaries. Recent product lines such as the ThrustSense Autothrottle, selected by the U.S. Army, exemplify the company’s ability to secure critical contracts.

Long-term Value Creation Strategy: 'IS&S Next'

With the launch of 'IS&S Next', the company is committed to a long-term growth strategy focusing on advanced avionics solutions, increasing internal manufacturing capabilities, and disciplined capital allocation. The introduction of the Utility Management System (UMS), an AI-capable system designed for enhanced crew efficiency, will enter flight testing in early 2025. This innovation underscores IS&S's commitment to integrating cutting-edge technology in their product line.

[Shahram Askarpour, executive]

Thank you, Paul, and good afternoon to everyone joining us on the call today. Let's begin with a high-level overview of our fourth quarter and full year financial performance.

This was a transformative year for IS&S, one in which we delivered significant year-over-year growth in revenue, net income, EBITDA and free cash flow. We generated net income of $7 million, which was up 16% from the prior year. In addition, total EBITDA was approximately $12 million, which was up 36% from the prior year and is up nearly threefold from just 3 years ago. During the fourth quarter, we delivered more than 18% year-over-year growth in revenue, driven by momentum from new military programs and recently acquired platforms. In recent quarters, demand across our military end markets has increased, supported by orders from both the U.S. Department of Defense and allied foreign militaries.

As a higher volume of backlog converts to revenue, we've realized improved operating leverage, a dynamic we expect to continue into the coming year. At a strategic level, we continue to build a growth platform centered exclusively on advanced avionics solutions for both commercial and military markets. Over time, our systems integration expertise has positioned IS&S as a preferred partner in the fleet modernization and retrofit markets, one whose in-house design, manufacturing, installation and support capabilities provide customers with safe, compliant and cost-effective solutions that enhance aircraft safety, compliance and mission readiness. We've built a strong reputation in the market that positions us to further scale our business moving forward.

Today, we are introducing IS&S [ Next ], our long-term value creation strategy. We consider this strategy the guiding framework for our next chapter of growth as we'll outline over the coming quarters. At a high level, our strategy centers on a combination of targeted commercial growth within high-value markets improving operating leverage and a disciplined returns-driven approach to capital allocation. While many of these elements are already at work in our existing business, we intend to provide more transparency around our progress under this strategy each quarter moving forward.

The first pillar of our growth strategy centers on targeted commercial growth within our core advanced avionics market verticals. Looking ahead, we expect commercial growth will come from several key areas, including the expansion of existing platforms, new original equipment manufacturer or OEM and retrofit programs, new product development and strategic product line acquisitions. In 2024, we delivered significant commercial growth through an expansion of our military business, continued growth in existing platforms and realized synergies resulting from our recent Honeywell product line acquisitions.

Our military end markets were very strong last year. And given our leadership in cockpit automation, we anticipate a continuation of this trend into 2025. Earlier this year, we announced a new foreign military platform with a major aerospace OEM to supply multifunction displays with an integrated mission computer. We've already begun executing under this contract and realize revenues in 2024. We also recently announced that our ThrustSense Autothrottle system was selected by the U.S. Army to be installed on the C-12 aircraft. This advanced technology will provide full flight envelope protection from takeoff to landing, including go around, enabling pilots to automatically control engine power settings for enhanced safety and efficiency.

Entering 2025, we are seeing several other similar opportunities with commercial customers entering our pipeline and anticipate that our work with both the U.S. DoD and allied foreign militaries will remain a significant growth engine for us in the year ahead. Within our commercial end markets, we continue to experience solid growth across existing platforms and OEM contracts. This includes Pilatus for our Utility Management System, Textron for our standby instrument and our autothrottle and on the military side, Boeing on KC-46A, KC-767 and the T-7 platforms.

On the heels of our recent Honeywell product line acquisitions, cross-selling synergies have increased as expected. These acquisitions have brought us the opportunity to cross-sell our existing products into new customer relationships acquired in the transactions while also selling new product lines to our legacy customers. New product development remains integral to our long-term growth. We continue to expand the sophistication of our cockpit automation technology through functionalities that enhance safety and reduce pilot workload. The integration of AI functionality to enhance cockpit automation remains a major area of focus for our industry over the coming years.

In early 2025, we will begin flight testing our new generation Utility Management System, or UMS, on the PC-24 platform with Pilatus. In layman's term, the UMS is to an aircraft what a CPU is to a laptop computer. It guides, controls and powers the most critical operating systems. Additionally, in 2025, we plan to launch our UMS2, which is a cutting-edge certifiable flight monitoring and control system. UMS2 is an AI-capable system, one whose integrated neural network processing capabilities significantly enhance crew efficiency by enabling additional cockpit automation. As our UMS2 is platform agnostic, we see significant growth potential for this product line over the next several years, particularly within the military and business aviation markets.

The second key pillar of our value creation strategy focuses on driving increased operating leverage across the organization. As we layer on higher base of revenue within our business, we anticipate improved fixed cost absorption and ultimately, a higher sustained run rate of EBITDA dollars. During 2025, we intend to increase the volume of maintenance, repair and overhaul work we handle at our Exton facility while also increasing the volume of subassemblies that are being manufactured internally. More on this shortly.

The final pillar of our value creation strategy focuses on a returns-driven approach towards capital allocation. We demonstrated our ability to successfully allocate capital during 2024, including both investments in our organic growth initiatives as well as the deployment of capital for product line acquisitions. Our organic growth investments included the addition of R&D staff and increased manufacturing headcount as we prepare to capitalize on higher sales volumes across our business. In 2025, we intend to increase our manufacturing capacity by more than 100% through a $6 million facility expansion. This investment will add a second subassemblies line as part of the 40,000 square foot addition. Subsequently, we anticipate this will provide us with the opportunity to acquire other strategic product lines in the future, further to my point earlier on increased operational efficiency.

The highlight of our capital allocation strategy during 2024 was clearly the additional acquisitions from Honeywell. We invested nearly $20 million in the 2 additional acquisitions during the year, positioning us to expand our capabilities, add new customers and open the door to significant cross-selling synergies entering 2025. In July 2024, we acquired additional key assets for certain communication and navigation product lines from Honeywell for roughly $4 million in consideration. This was followed in September 2024 with the acquisition of various generations of military display generators and flight control computers from Honeywell for $14 million in cash. As we have discussed, these acquisitions provide us with several unique opportunities to drive profit uplift through the in-sourcing of certain components, the potential to bring more maintenance and repair work in-house as well as attractive revenue synergy opportunities.

In conclusion, 2024 represented over 30% growth in revenue and adjusted EBITDA, and we expect similar growth in 2025, exclusive of any future acquisition opportunities. We intend to remain an opportunistic acquirer of complementary product lines that expand our capabilities in advanced avionics. We believe our collective focus on commercial growth, operational efficiency and disciplined capital allocation position IS&S for sustained value creation in the year ahead, and we look forward to having you join us on that journey.

With that, I'll turn the call over to Jeff for his prepared remarks.

[Jeffrey DiGiovanni, executive]

Thank you, Shahram, and good afternoon to all those joining us. Today, I will provide a high-level overview of our fourth quarter performance, including a discussion of our working capital, balance sheet and liquidity profile at quarter end. We generated net revenues of $15.4 million in the fourth quarter, up 18% when compared to the fourth quarter last year. The increase was driven by contribution from the recently acquired Honeywell product lines, growing momentum in new military programs as well as revenue synergies from the Honeywell platforms acquired last year.

It is worth noting that our fourth quarter 2024 revenues were impacted by a $1.7 million true-up payment for services performed by third-parties. Additionally, we were pleased to see continued stabilization in the air transport market, and we saw sequential growth in this market when compared to the first half of the year.

Product sales increased to $9.8 million during the fourth quarter, driven by contribution from our commercial air transport programs. Customer service revenue was $5.5 million, owing largely to the customer service sales from the product lines acquired from Honeywell. Gross profit was $8.5 million during the fourth quarter, up $8.1 million in the same period last year, driven by strong revenue growth, partially offset by the higher depreciation and amortization expense resulting from the Honeywell acquisitions and continued investments in growth initiatives.

On that note, I think it's important to recalibrate expectations around our recent gross margin performance and our anticipated margin outlook entering 2025. There are 2 primary factors that have impacted gross margin capture in recent quarters. The first factor is related to the incremental depreciation and amortization that has resulted from recent product line acquisitions. As we continue to complete product line acquisitions in the future, we expect that this will be an ongoing margin headwind.

The second factor involves the forward shift in our sales mix. Historically, military sales represent less than 1/3 of sales, while 2025 due to the recent acquisition, it will be a higher percent of sales. Generally, military sales carry a lower average gross margin versus commercial contracts. However, given the significant potential we see for absolute EBITDA dollar growth in military, we believe this is good for us and work that we will continue to pursue as it advances our focus on improved operating leverage.

Given these factors, we expect our consolidated gross margins will likely trend closer toward mid-50% on a normalized basis over the intermediate term, which is below historical levels. However, we anticipate that with our improved top line growth profile, we'll be able to drive increased adjusted EBITDA margin realization and profitability over time. Consequently, we believe adjusted EBITDA margin and expansion will be a comparably better measure of our relative performance over time than gross margins.

Research and development expense during the fourth quarter of 2024 was $1.1 million, an increase from approximately $740,000 in the comparable period last year. This increase was driven by growth in our product development efforts in support of our long-term growth strategy. Fourth quarter 2024 selling, general and administrative expenses were $3.1 million, a decrease of $3.7 million from last year. The decrease in SG&A expense in the quarter was primarily the result of some onetime expenses included in the prior year results, partially offset by incremental amortization expense related to the acquired Honeywell product lines.

Fourth quarter net income was $3.2 million or $0.18 per diluted share compared to net income of $2.6 million or $0.15 per diluted share a year ago -- a year a quarter ago. Adjusted EBITDA was $5.6 million during the fourth quarter, up from $4.8 million last year due to our strong revenue growth and operating expense leverage.

Moving on to backlog. New orders in the fourth quarter of fiscal 2024 were $95.4 million, which includes $74.3 million of backlog acquired as part of the product line acquisition announced on September 27, 2024, and backlog as of September 30, 2024, was $89.2 million. This backlog includes only purchase orders in hand and excludes orders from the company's OEM customers under long-term programs, including Pilatus PC-24, Textron King Air, Boeing T-7, the Boeing KC-46A and Lockheed Martin. We expect these programs to remain in production for several years and anticipate that they will continue to generate future sales. Further, due to the nature, the product lines from Honeywell do not typically enter backlog.

Now turning to cash flow. During fiscal 2024, cash flow from operations was $5.8 million, up $2.1 million in the year ago comparable period. The improvement was driven by higher cash earnings and improved working capital efficiency. Capital expenditures were $700,000 during the fiscal 2024 versus $300,000 in the same period last year. As a result of these factors, free cash flow for the full year 2024 was $5.1 million, up from $1.8 million last year.

Total net debt as of September 30, 2024, was $27.5 million, up from $16.4 million at the end of 2023, reflecting the incremental debt to fund the recent Honeywell transactions. This was partially offset by our strong free cash flow generation during the year. Our net leverage at the end of the fourth quarter was 2x. We recently amended our credit agreement with PNC Bank to expand the facility to $35 million. Our total cash and availability under our credit lines was $7.5 million at the end of the fourth quarter, which provides us financial flexibility to support our ongoing operations and facility expansion.

That completes our prepared remarks. Operator, we're now ready for a question-and-answer portion of the call.

[Operator]

[Operator Instructions] The first question comes from Andrew Rem with Odinson Partners.

[Andrew Rem, analyst]

Maybe if I could start, I'm going to call it the Honeywell acquisition #3, the one you announced in early October. Can you give us a perspective on like the revenue and EBITDA contribution? Or just give us some sense of what that acquisition looks like and impact on FY '25?

[Shahram Askarpour, executive]

Well, first of all, Andrew, yes, we did the acquisition in September. There is -- are we going to be putting out backlog information?

[Jeffrey DiGiovanni, executive]

Yes. So Andrew, a couple of things on that one. Under that acquisition, the backlog came on around $74 million. So in our backlog, you include about $74 million of backlog acquired on that acquisition, which is production. So that's going to bleed off over probably a 3- to 4-year period. And military has lower margins than commercial.

[Shahram Askarpour, executive]

In terms of EBITDA, the margins, we believe it is going to be similar to our EBITDA margins because of the volume.

[Andrew Rem, analyst]

Just to clarify you're saying that -- I think you said it in your prepared remarks as well, gross margin is lower, but were you saying EBITDA margins are closer to being similar or those also are a little lower?

[Shahram Askarpour, executive]

Comparable to what we have because the way we look at it is that it's an addition, it doesn't significantly increase our SG&A or engineering. So it's -- in a lot of ways, when you look at it, the gross margins fall into EBITDA.

[Andrew Rem, analyst]

Okay. And on the backlog, should we -- does it necessarily burn off linearly? Or can it be more chunky over -- from 1 year to --

[Shahram Askarpour, executive]

Yes. I mean part of the backlog being what it is was that there was an obsolescence issue that Honeywell resolved a few months ago. And because of that obsolescence issue, the deliveries over the prior year or so were very limited. So there is a catch-up that's going to be done in 2025. And it's still a little bit too early for us to be able to accurately say how much of that is going to be done in 2025 because Honeywell is going to continue operating this product line, at least for another 3 -- 4 months before it comes to us, and there's going to be a shutdown period as we experienced before, while all the test equipment gets transferred here.

So if I was to be a guessing man, I would say our Q2 is going to see a big bump in revenue from this. Q3 probably would be the transition quarter would be a bit -- you'll going to get a dip and kind of it will hopefully recover by Q4. But I think some of the backlog, its period of performance is over 4 years. And some of it is just behind the 8 ball that we've got to ship as soon as we can.

[Andrew Rem, analyst]

Okay. And then, Jeff, you mentioned the $1.7 million true-up payment. Which segment does that fall in?

[Jeffrey DiGiovanni, executive]

That will fall in the customer service segment.

[Andrew Rem, analyst]

Okay. And then on CapEx, I think you guys said $6 million. Is that all in FY '25?

[Shahram Askarpour, executive]

Some of it we already spent in FY '24.

[Jeffrey DiGiovanni, executive]

Very little.

[Shahram Askarpour, executive]

Yes.

[Jeffrey DiGiovanni, executive]

So some in '24, but majority -- all that's going to be fiscal 2025.

[Shahram Askarpour, executive]

All the architectural work and all the design work and preliminary to get timing permissions and all of that. I think we paid for all that in '24.

[Jeffrey DiGiovanni, executive]

Right. So now you're moving forward with the construction in fiscal '25. So you'll see that in the CapEx going in 2025.

[Andrew Rem, analyst]

And when do you expect to complete all that work in fiscal '25?

[Shahram Askarpour, executive]

June. If any construction is completed on time.

[Operator]

The next question comes from Doug Ruth with Lenox Financial Services.

[Douglas Ruth, analyst]

I also want to congratulate you on the strong quarter. It's -- you really gave us a lot of information. Is there any way that you can give us any kind of projection what Q1 might look like as far as revenue?

[Shahram Askarpour, executive]

For the quarter that we're in right now?

[Jeffrey DiGiovanni, executive]

Unfortunately, we don't provide the forward-looking statements.

[Shahram Askarpour, executive]

Yes. I think I'll wait until February for that.

[Douglas Ruth, analyst]

Yes. Okay. And is this the norm in your business to say that the backlog could take up to 4 years to earn out?

[Shahram Askarpour, executive]

It depends on -- I mean, these are -- some of these are military contracts and their production contracts. I mean, typically, for IS&S, when we have production contracts, we get releases maybe 18 months releases or a year releases. This is -- our backlog is usually not of this magnitude. These are military contracts and some of them are with Lockheed, they're on production contracts and Lockheed had, for some of these, they've gone out and issued purchase orders over the next 4 years. For us, it's not typical, but this is new.

[Douglas Ruth, analyst]

Okay. And then can you -- you mentioned that you thought that the Q2 was -- you called it a big bump. Could you explain that a little bit more? What you see happening in that quarter?

[Shahram Askarpour, executive]

Yes. So well -- I mean, if you remember, when we did the acquisition from -- the first acquisition from Honeywell, the first quarter for it was our Q4 of 2023, where we got like a $6 million revenue that came from Honeywell.

[Douglas Ruth, analyst]

Yes. I remember that.

[Shahram Askarpour, executive]

And that was because -- yes, because the next quarter, they were planning on packing all the test equipment and shipping it to us. So they typically do as much pull-in as they can in the prior quarter before shipping the equipment to make sure the customer has enough equipment to support them while we go through this transition phase. That quarter where that's going to happen looks like it's going to be Q2 of our financial 2025. So between January to March, we anticipate Honeywell is going to ship a lot of this equipment to Lockheed before they tear down the equipment to send it to us.

[Douglas Ruth, analyst]

Okay. And my final question, could you tell us what the 3 highest priorities are for fiscal 2025?

[Shahram Askarpour, executive]

So there is -- yes, I mean, there is -- I thought we outlined that in our speech, but we've got product development where we're looking at launching our latest generation, which is -- has a lot of artificial intelligence capabilities, is certifiable artificial intelligence, which is unique in our industry at this point. So that product, we're going to be launching it. We're going to finish the flight test with Pilatus for the PC-24 version of that Utility Management System.

Another priority for us is in-sourcing a lot of the subassemblies and that would allow us to hopefully increase our gross margins. I think our gross margins gradually -- we hit a low of in low 50% middle of last year. And as we've kind of gained some efficiency and learning curve of our technicians, we've built it up to mid-50s. We like to be able to maintain that long term. And one way to do that because as long as we're doing acquisitions, there's always going to be inefficiencies and you're going to be training new technicians while other technicians are doing the work. So the way we can increase -- the way we can maintain that mid-50% ranges is by increasing the in-sourcing of the subassemblies. So that's a big focus for us.

And then -- and the final is continue with our capital allocation of opportunistically identifying products that fit our profile and acquiring them. And that's -- those are the 3 things that are priorities for us.

[Douglas Ruth, analyst]

I want to again congratulate you on a very strong quarter.

[Operator]

The next question comes from Gowshi Sri with Singular Research.

[Gowshihan Sriharan, analyst]

Can you hear me?

[Operator]

Yes.

[Gowshihan Sriharan, analyst]

The first question is with the recent wins on the military side, the U.S. Army C fleet, could you give us color on what you're excited about in the military space? And what are you guys doing that is helping you win market share? And what's making you competitive in this space? And how do you build momentum in that space?

[Shahram Askarpour, executive]

So I mean, essentially what we've done with the shift in strategy. I'll go back to a few years ago where they put a sequestration of dollars and the military budget got cut significantly. At the time, the strategy of our company became to shift our focus from military more towards the commercial side of things, which is what we did. 3 years ago, when I took over, I started building our military business development team and to focus on getting more military business. it takes a while for these things to start paying off. So what we've seen so far, we've seen positive results. I think the autothrottle for the U.S. Army, autothrottle is a product that we developed many years ago, and we had not been successful in marketing it to the military. We've been selling it to Textron as a forward fit under King Air. But the U.S. Army, the U.S. Air Force, U.S. Navy, they have a number of these King Air C-12s and they could use the autothrottle.

About just over a year ago, we got selected by METS, which is the Multi-Engine Training System for the U.S. Navy. And now the U.S. Army selected us for their C-12 platforms, and we continue marketing that into the military side. We won this other program for mission computer and the display. And we've got -- we actually got several other opportunities on the mission computer side of things that we're looking to explore. The acquisition we did from Honeywell for the F-16 flight control computer and the mission computer is going to open a lot of doors for us in terms of being at the table with the Lockheed and taking opportunity of other product lines that they are looking to acquire.

[Gowshihan Sriharan, analyst]

Okay. Okay. That's good color. Given the increasing military presence, what are the potential challenges in a longer sales cycle at a more complex procurement process? Can you give us some color on what -- how you manage that or stay responsive in your R&D and product development space?

[Shahram Askarpour, executive]

Yes, I mean the sales cycles are longer. But like I said, we started down that line about 3 years ago, and we're beginning to see fruits of those efforts, and we're going to continue down that path. I mean some of the things we're doing now in our organization in anticipation of some of the new contracts we're getting is making our facility more secure that we're putting a lot of controls in place. So we can take on secret programs from our military as well as putting in a system that can withstand government accounting audits and all of that.

So we've changed our MRP system, which is going to go live early 2025. We've been working on it for about a year now and because our ERP system is kind of old and antiquated. So that would allow us to be able to easily show kind of costs to the government and be able to categorize expenses differently the way the government wants to see it. So we've put in a lot of efforts into the infrastructure that would get us to a point that we can become a serious defense contract.

[Gowshihan Sriharan, analyst]

And given your strategy that you mentioned, the next strategy, what percentage of revenue ideally would you think in 1 to 3 years would be military sector?

[Shahram Askarpour, executive]

So I think on average, about -- just about less than 1/3 of our business used to be military. I guess last year, that went down because of the acquisitions we did with Honeywell that were mainly focused towards the commercial side. I think this year, military is going to be pretty large because of that new acquisition we did from Honeywell on the F-16. I think long term, we like the idea of having third military, third business aviation and third air transport. That's formulas worked for us for over 35 years, and we like to see it that way. But as you grow, you got to grow every sector. And when you say I'm going to grow my military fivefold because I'm going to grow the business fivefold, then that becomes significant enough that you need to put some controls in place.

[Gowshihan Sriharan, analyst]

Okay. Okay. And I think you mentioned this about your USM2, but with the cockpit space, how do you see the interplay between military and commercial technologies evolving? Are there any other specific -- I think you mentioned the USM2 is agnostic. But is there any specific synergies or cross-[ foundation ] opportunities that you're targeting?

[Shahram Askarpour, executive]

Well, I think our -- again, our product development strategy from day 1 was that we made one product, and we sold that product to the military, to the commercial aviation as well as air transport. Now there are variation of it that go into the military. For example, we make the same display that we put in the 757/67. We put them in the C-130s, but the one that goes in the C-130 has night vision capability. So it's got 2 sets of lighting for light sensing. But the -- kind of the backbone of the technology is the same. And going forward, we continue developing our products, like, for example, the UMS that we made for Pilatus, it was very much one platform product. We developed it specifically for Pilatus. When we came, they wanted to do a more capable UMS, which we've been developing with them, and that's the one that's going to go into flight test. I think it's scheduled for March or April.

When we did that, we started taking account into, okay, how do we now make this more universal that we can put it in military aircraft as well, as well as put it in other business aircraft. And one of the things that became apparent is that if you're putting a flight control computer in the military aircraft today, they want to see artificial intelligence capabilities in it. So we added the artificial intelligence core to this product line, so we can cross-sell it in the military as well as in the business aviation side, utilize it for more cockpit automation.

[Gowshihan Sriharan, analyst]

Okay. And my last question is, given the issues at Boeing, do you see any kind of potential lift in terms of retrofit opportunities? Or how do you see that playing out [indiscernible]?

[Jeffrey DiGiovanni, executive]

So I think your question is saying, the Boeing issues are having, how does that affect IS&S?

[Shahram Askarpour, executive]

No, it's really good for IS&S. Not that we want them to have issues. But as long as they can't make new airplanes, people are going to fix their old airplanes.

[Jeffrey DiGiovanni, executive]

So you're going to see that aging airframes, still a lot of repairs and maintenance, parts sales, spare sales and the market overall going up in aerospace because of that.
