Littelfuse, Inc.

bookings, up more than 20% versus the prior year. Avi will discuss specific results and our outlook in more detail shortly, but I want to thank our global teams for their persistent hard work and efforts. Now I want to share the progress we're making as we enhance our focus on future growth opportunities. Our end markets require increasingly higher power and higher energy density solutions from LittleFuse. We are seeing broad-based momentum reflected in our 2025 design wins, which were up double-digit relative to the prior year. Today, I want to specifically highlight our grid and utility infrastructure opportunity. If you turn to slide six, our position in this high growth market was significantly bolstered by the closing of a Bassel Electric acquisition this past December. With approximately $3 trillion expected to be invested in grid modernization through 2030, the market is demanding more advanced and higher power protection and excitation systems. With the strategic timing of the acquisition, we are well positioned to help our expanding grid and utility customer base navigate the challenges of higher voltages and increasingly complex system requirements. Bassler enhances our core high-power protection capabilities and equips us to sell more complete solutions. We believe our complementary portfolio, coupled with our deeply embedded relationships, positions us for double-digit growth and strong profitability within this market. An example of our expanding reach. This quarter, BASA was selected as a design partner for a next generation control system solution for a leading player in the high power industrial and data center backup generator market. Now turning to our second strategic priority, which is to work more closely with our customers to help better understand and solve their technology challenges. Our new go-to-market evolution is live, and we're seeing the early signs of success following our Salesforce realignment, which is now market-facing, customer-centric, and focused on solving our customers' most complex challenges with our complete technology portfolio. As an example, we continue to drive significant progress in the data center market, where we were early to adapt our new sales model. Our 2025 data center design wins more than doubled relative to the prior year. As you can see on slide seven, we have a comprehensive data center technology portfolio, and we are capturing meaningful wins with leading hyperscaler, cloud, and infrastructure customers. The data center market is undergoing a significant architectural shift to high-power systems. As shown on slide 8, we believe our content opportunity on these next-generation architectures will be significantly more than double current levels. Importantly, we also have meaningful growth opportunities across the data center infrastructure ecosystem, and the acquisition of Bassler further expands our high-power data center infrastructure capabilities. To illustrate our momentum, we secured a significant design win for a static transfer switch with a leading data center infrastructure provider. This solution leverages our high-powered semiconductor and packaging technology, which enables increased power density of approximately 20%, improved efficiency, and simplified integration into the customer's equipment. This win is for a 2-megawatt UPS bypass and power distribution unit application that enables uninterrupted power to data center racks. Shipments are slated to begin in the first half of 2026, representing continued momentum and growth in high-powered data center solutions. Turning to our third strategic priority, enhancing operational excellence. Today, I want to highlight our semiconductor business opportunities. This business is core to our technology differentiation. Our market leading protection and complementary power semiconductor products are critical to our mission of enabling a safe and efficient transfer of electrical energy. Last quarter, we shared that we made a change in semiconductor leadership. I would like to provide an update on the strategic progress we're making in optimizing our power semiconductor products, which accounts for roughly half our semiconductor business. First, we have made a decision to sharpen our focus on high value and high growth applications. We have differentiated technology and strong customer relationships in high power markets, such as data center, battery energy storage, grid and utility infrastructure. We have started the process of rationalizing our portfolio to reduce exposure to lower value product families and are aligning our manufacturing strategy accordingly. As part of this initiative, we are reviewing our power semiconductor manufacturing footprint to ensure it is optimized and resilient. We believe these actions will significantly improve the strategic focus and profitability of the business and position us to deliver next-generation technologies that will drive growth in our targeted markets. We look forward to providing further updates on these initiatives and sharing our formal strategic and financial roadmap at our May Investor Day. Taking a step back, we closed 2025 with considerable momentum, reflected in our fourth quarter performance. We closed the Basler acquisition and drove robust backlog through customer and market traction throughout year end. Into 2026, we are focused on executing our three strategic priorities and believe we are positioning LittleFuse today for meaningful long-term scale and leading shareholder performance. With that, I'll hand the call over to Abhi.

Thank you, Greg, and to everyone joining us. Today, I will start with an update on the Basler acquisition. Then, I will walk you through our fourth quarter results followed by our first quarter outlook. We'll then be happy to take your questions. As Greg mentioned previously, we're excited to close the acquisition and look forward to executing on the meaningful revenue synergies and opportunities that the combination of Basler and Little Fees will deliver. We anticipate the acquisition will contribute between $130 and $135 million in revenue and 10 to 15 cents of adjusted earnings in 2026. We also expect Basler to deliver a high teens adjusted EBITDA margin for the year. With that, please turn to slide 10 for details on our fourth quarter. Going forward, comparisons I will discuss will be relative to the prior year, unless stated otherwise. We delivered strong results as revenue in the quarter was $594 million, up 12%, and up 7% organically. The Dortmund and Basel acquisitions contributed 3% to sales growth, while FX was a 2% tailwind. Adjusted EBITDA margin finished at 20.5%, up 480 basis points, reflecting meaningful operational leverage, while fourth quarter adjusted diluted earnings were $2.69. We also delivered meaningful cash generation in the fourth quarter. Operating cash flow was $139 million, and we generated $120 million in free cash flow. We ended the quarter with $563 million of cash on hand and net debt to EBITDA leverage of 1.2 times. In the quarter, we returned $19 million to shareholders via our dividend. Now, before we go into further details on our results and outlook, I wanted to discuss the non-cash goodwill impairment charge that we recorded in the fourth quarter. The impairment charge of $301 million is for the ICSIS endorsement acquisitions and is the result of our annual impairment testing of our reporting units. It reflects weaker sales and profitability than original expectations amid persistent soft market conditions. As Greg mentioned, we have an opportunity to enhance our power semiconductor's focus on applications and markets where we have strong market share, brand power, and technology expertise. With a sharpened strategy, power semis will better complement our market-leading protection capabilities and ultimately drive improved performance over the long term. Please turn to slide 12 for brief highlights on our full-year 2025 performance. We delivered strong revenue growth of 9%. while adjusted EBITDA margin expanded 250 basis points to 20.9%, reflecting the focused execution of our strategic priorities. We also delivered robust cash flow for the year, with free cash flow expanding 26%, showcasing the strength of our operating model. We continue to target free cash flow conversion of more than 100% in 2026. Please turn to slide 13 for our segment highlights, starting with the electronics product segment. Sales for the quarter were up 21%, led by strong passive products organic sales, as well as growth contributions from protection semiconductor products. Adjusted EBITDA margin of 23.7% was up 370 basis points, reflecting favorable year-over-year passive and protection volume leverage. For the full year, sales increased 13%, while adjusted EBITDA margin expanded 190 basis points, driven by solid volume leverage. Moving to our transportation product segment on slide 14. Fourth quarter sales increased 1% year-over-year, but declined 1% organically. Passenger vehicle organic sales growth was more than offset by softer commercial vehicle volumes. Adjusted EBITDA was 16%, reflecting our team's focus on driving margin expansion in a continued soft transportation market environment. For the full year, Our focus on operational execution led to solid margin expansion, and we remain confident in our ability to drive long-term transportation profitability and enhancements despite continued soft market conditions into 2026. Turning to slide 15, industrial product segment sales increased plus 4%, but declined 1% organically for the quarter as improved energy storage Utility and grid infrastructure, renewables, and data center demand was more than offset by lower HVAC demand. Fourth quarter adjusted EBITDA margin was 16.2%. For the full year, our industrial segment delivered revenue growth of plus 10%, reflecting our secular growth positioning. Salt full year 2025 adjusted EBITDA margin expansion reflects favorable volume leverage while we continue to invest in long-term growth. Please move to slide 16 for a first quarter outlook. We entered 2026 with a strong backlog and significant momentum. With that in mind, our first quarter 2026 guidance incorporates current market conditions, trade policies, commodity prices, and FX rates as of today. We expect first quarter sales in the range of 625 to 645 million, which assumes 7% organic growth at the midpoint and five points of growth from a bachelor acquisition. We are projecting first quarter EPS to be in the range of $2.70 to $2.90, which assumes 25% flow through at the midpoint, as well as a $0.03 contribution from the BASA acquisition. Turning to slide 18, we want to provide you with a view on our key market exposures and underlying growth assumptions for 2026. We look forward to sharing our full strategy with you at our May 14th Investor Day in New York. With that, operator, please open the call for Q&A.

This time to ask a question, simply press star followed by the number one on your telephone keypad. Again, that is star one to ask a question. And our first question comes from the line of Luke Junkard, Junk with Baird. Please go ahead.

Good morning. Thank you for taking the questions. Greg, maybe if we could start with data center. Obviously, it's emerged as a big part of the story over the past year. Just hoping you can help us think through some of the key incremental drivers as we move through not only in the first quarter, but through 26 in terms of share gain opportunity flowing through that 2X backlog growth that you cited for the full year and maybe even initial tailwinds from those higher voltage sockets starting to launch. You mentioned the award in the script that first half 26 shipments are starting there. Just how should we kind of scale in the opportunities we go through this year? Thank you.

Yeah, thank you, Luke, for the question. Good morning. We continue to see good progress in the data center market. I think I emphasized that data center is one of the early markets where we focused on our sales realignment, putting a dedicated team focused on our customers, selling our complete technology portfolio, and we're already seeing traction. As I mentioned, our design wins were up significantly, more than doubled in 2025, and we continue to see momentum. And I think the good news, as is shown on the chart, As the customers are moving to higher voltage systems, their architectures are higher voltage and DC high voltage systems. There's a lot more opportunity for us. And we're part of those conversations with our customers now on architecting that. So we can't give a quantitative number exactly because the architecture are evolving, but it's at least twice. the opportunity for us as we go to the higher voltage systems that in some cases significantly more than that. So we have momentum. I mentioned the design went on the static transfer switch. We have momentum across the business. Also, Bassler has good position and data center for backup power generation solutions. And so, as we mentioned, it's not just in the rack and the light space, but actually more and more solutions that we offer in the gray space as well. So we have good momentum. We continue to see growth in design wins. We will continue to see growth in revenue. And I just say that the thing I'm most excited about is we're having deeper conversations with our customers, talking about more of our technology portfolio, talking about next-generation architectures around the high-voltage solutions.

And look, just to build up on what Greg said, so again, to reemphasize that design wins were two times, you know, 2024 and 2025. Data Center grew really, you know, grew strong double digits in the quarter and was a material contributor to our growth story in Q4. We expect it to be a leading market contributor growth in 26. And then more importantly, as I think about our data center exposure, it's double digits as a percentage of revenue, inclusive of Bassler, as I think about our data center exposure.

Very helpful. And then, Greg, switching gears to industrial, you mentioned in the script that you're seeing signs of a more broad-based recovery in industrial into 26. Just hoping you could double click on that in terms of some of the maybe more specific things that you're seeing, or obviously this touches a few parts of the business, maybe flow through to some specific business impacts as well.

Thank you. Yeah. Thank you, Luke. Yeah. I would say that, you know, if you look at the bookings we had in 4Q and the momentum we feel, we're seeing a broader based, a broader based momentum, I would call it in our, in our broader industrial market, especially like our diversified industrial segments and industrial automation segments. The one market where I would say we still continue to see softness is in the residential HVAC, where we have a reasonable exposure on our industrial business. So that one continues soft, but broadly the market is improving. And I would say the good news is, is that we see that broad momentum across the business. It's strong in our industrial products and our passive electronics and also our semiconductor protection. The book to build in the quarter was above one and we're seeing growth in not just book-to-bill, but also in POS through to our end customers.

Yeah, and just the last one I'll make is if you think about the bookings in Q4, we're up 20%. We saw similar numbers in Q3, so it points to, again, strong momentum exiting 25 and coming into 2026 to the next point.

Yeah, and then maybe for my last question, obviously there's a lot of metals inflation out there right now. Can you just remind us how you buy things like copper and silver in terms of buying at spot rates versus indexing your mechanisms to pass through those higher costs to different customer types, some distribution, a little more straightforward versus some other customers, and maybe put a finer point on what you're assuming in the first quarter guidance specifically.

Thank you. Yeah, absolutely. Look, so we're seeing pressure on the metal side. Our exposure is primarily to copper and ruthenium. But given the volatility in the silver and gold prices, we're also seeing an impact from that. So they kind of think about what our teams are focused on. Firstly, they're focused on supply chain opportunities and really looking at alternate ways to go procure that same material for cheaper pricing. Two, it's around how do we go price that and take that inflation and price it along to our customers, either through pricing or surcharges. What I will tell you is while we're getting impacted, you know, just like 2025, right? If you think about the price cost tied to tariff, our teams did a great job managing that. That's what we're focused on. That's what we plan to go do this year. Now, there might be some timing between quarters, just given the timing of inflation versus when you, you know, get your price. But that said, our goal is to be price-cost neutral. We have factored the impact of current commodity prices in our Q1 guide and feel reasonably comfortable about where we are and the Q1 guide.

Yeah, just maybe in terms of the first quarter guide, is the assumption that your price cost neutral in the first quarter guide, or should we think of that as a full-year comment?

I think it's a full-year comment. Like I said, there will be a timing loop throughout the year as we go through it, depending on how the commodity pricing moves versus when we recognize the pricing on it. So that's a full-year comment, not a Q1 comment. Understood. I'll leave it there. Thank you.

Your next question comes from the line of Christopher Glenn with Oppenheimer. Please go ahead.

And yeah, congrats on the deal and the data center momentum there. You know, you answered a lot of questions up front about, you know, migration to the higher voltage architectures. You know, obviously you get some constructive comments there and that of some product categories that will diminish. So that's great. Still a question remaining. I'm curious about, you know, what you're seeing in terms of opportunities like partnerships or consortiums into that space versus standard application design. And I'm just wondering if there's, you know, anything to talk about in that respect.

Well, I think, yeah, thank you, Chris. I think the thing to understand is that we have increased focus on the data center market. And we're wanting to play across the ecosystem. So we're partnering and talking to the hyperscalers. We're partnering and talking to the chip providers that build the architectures. We're very active in the ODM and the design ecosystem in Asia and Taiwan that supports the design ecosystem. And so what's important about our strategy now is that we have a dedicated focus, a dedicated sales focus on the data center customers and increased focus. And I think what's important is that we participate in all parts of that. from the chip designers that are building architectures to the hyperscalers that are designing architectures and power to the ODM in Asia. And we're covering all of that and we're participating in all of that. And our view is that we get our products architected and designed in throughout the cycle and we're touching all those phases. So we're very active. We're also very active in platforms like Open Compute, for example, to make sure we understand where the architectures are going, where the standards are going. One other thing I will emphasize that When you go to high voltage architectures, many of these high voltage architectures, once you go to 400 or 800 volts, products that didn't used to need to be UL certified, for example, now need to be UL certified. We need new standards. We're active in the standard body in the UL certification process for some of the standard setting processes for these high power applications that ultimately are going to go into data center. So we're participating across the ecosystem. That's actually how we think we're going to win. And we're increasingly investing in that.

Great. And then on the power semis, you kind of blew through some of the target markets focused there. So I'd like to just revisit that. And also, you know, what kind of attrition might we anticipate in kind of related earnings power? How should we contemplate that element ahead of the kind of breakout in May?

Yeah, thank you, Chris. I'm going to try to give a little bit more color. So again, just to anchor on our semiconductor business, which is in our electronic segment, About half the business is our protection semiconductor business. This is actually a model franchise for us. We have very good market position, strong share, good customer value. So that's about half the revenue. And then the other half is our complimentary power semi-business, which is core to our strategy. And I think where we're focused here, though, is that there's elements of the power semi-business where we have high value, we see high growth markets, we have meaningful share, we're important to our customers. And actually those tend to be the higher energy density, high power segments, like data center, battery, energy, storage, grid, and utility customers. And so those are the areas where we're going to continue to focus where we have high value, where we have market position, that's giving us differentiated solutions. There are however, parts of our power semi portfolio, whereas lower value and a little bit more commoditized, I would say where we don't have as much value. And so we're undergoing an effort to rationalize the portfolio. and double down on the areas where we believe we can win. And as part of that, we will also be optimizing our manufacturing footprint. So what I think we're telling you is that this is a work in progress. We're telling you where we are. We look forward to giving you continued updates as we progress this between now and investor day in May. So we will continue to give updates as we make progress. But I think the strategic focus is to continue to, just like we're doing broadly for the company, sharpen our focus on where we play and why we win.

Yeah, Chris, just to build on Greg's commentary, I think the way to think about it from a financial standpoint is as we go through the year, as we make progress, we'll incorporate any changes to our guide. That's point number one. Point number two, again, to Greg's point, our semiconductor business unit is made up of two things really, right? It's protection and it's power. Protection is a model franchise. So what this also does give us an ability to go do is as we rationalize our portfolio, optimize our footprint, get up our semi-business at that model level profitability, right? That's what we're focused on. Again, more to come on this, but to Greg's point, our efforts are underway. And as we make progress through the year, we'll keep you up to date. And then more importantly, have a vision and a roadmap by investor day so that the team understands what is it that we're going after.

Perfect. And then if I could sneak one in on Bassler, just curious about how you're seeing the Chris Wanner, Cultural fit anything kind of edgy on the integration, you know, probably some differences and go to go to market and specification process with a little bit more of a systems and solution orientation to their portfolio.

Chris Wanner, yeah Thank you Chris yeah I look, we are very excited to have bachelor as part of little fuse. Chris Wanner, As I mentioned, I got the you know we did the due diligence, but that was kind of a limited process, so I got the opportunity to meet with the team shortly after closing December. Um, what, what we really like, and actually I left even more excited about is, is that a couple of things, one bachelor is a high, highly technical organization. They have a great engineering capability, their market leaders and protection solution, excitation systems, and probably punch above their weight. Based on the size of the company for the capabilities that they have to, though, you mentioned go to market. We really like about bachelor is that they have market position. and establish go-to-market in the utility industry. If you look at LittleFuse's legacy portfolio, we have technology that really plays in grid utility. And some sub-segments of that, like battery storage and solar, we've done really well. But other sub-segments that may be more core utility grid space, we have under-participated mainly because of focus. But one of the key areas is that we didn't have the channel. So we're actually really excited about Bassler and the capabilities they bring. They have complementary products. They're a system-level provider. They provide complete solutions. So many of the places we're going, Bassler is. And our goal is to leverage their go-to-market and customer understanding to help us bring more of the LittleFuse portfolio into that space. So just like we're doing other places, we're leveraging that. We're very pleased to have the Bassler engineering and go-to-market team as part of LittleFuse. And we see that as a growth synergy out of this acquisition.

Great. Thank you.

As a reminder, to ask a question, press star one on your telephone keypad. And our next question comes from David Wilgams with Benchmark. Please go ahead.

Hey, congratulations on the progress here. It's really great to see, and obviously the tone has changed and much more enthusiastic, so congratulations there. Maybe the first question is, Greg, as you kind of think about over the last 90 days, what has changed or shifted? What do you think has become maybe more positive? And is it simply because of the self-help, the strategy you've implemented, or do you feel like the markets are also helping in that regard?

Yeah, so two things. First, I think we're on a multi-year journey, and I think that from the LittleFuse perspective, we are continually making progress. So we've been making progress throughout 25, and we anticipate we're going to continue to make progress through 26. And so for us, I would say it's a multi-year journey. And we are seeing results of our progress. We expect to continue that. In addition to that, I would say we continue to see market momentum. So if you go back to 2025, I think the market momentum was maybe more narrow in data center and grid utilities, solar, battery storage, energy around data center. the market momentum was a little more narrow. We actually are seeing a little bit broader market momentum. We talked about the broader industrial market momentum. So I would say it's both, right? We are making progress on our strategy. It's a journey. It's, you know, step-by-step we're making progress, but also we're seeing some market momentum that is adding to that.

Yeah. David, just to build on what Greg said, I think a couple of things I'll add to it. First of all, as you see our results for 25, right? We talked a lot about operational execution. While we have more to go do there, you see that play itself out in our margin expansion across all three segments, whether it's transportation, industrial, or electronics. I think the whole conversation we just had around power semi and that focus really gives us an opportunity to optimize our profitability and continue to move that profitability to optimal levels. So I think to Greg's point, I think there's a little bit of focus that we're driving that helps us optimize our portfolio further. And then, Gregory, talk to market momentum.

Okay, great. Thanks so much for the color. And maybe secondly, just as we think about for the full year and margins and maybe even on the top line, what do you think is a reasonable place to kind of think about where growth could be this year, just given all of the positive dynamics that we see here? Is it reasonable to assume double-digit growth for the full year, you think?

Yeah, so look, we don't definitely got full years, but I'll tell you, I think I come back to, if you look at our Q1 guide, right? I mean, at the midpoint, it's a 7% organic. 15% growth year-over-year, where Sembasa is going to contribute about 5% in the quarter, and an EPS guide that the midpoint is a 28% growth and a 7% top-line growth. So again, points to the strong momentum exiting 25, coming into 26. As I think about the markets, as Greg mentioned, we're seeing broad-based industrial strength, with the exception of the HVAC market. It's not just data center anymore, it's a little more broad-based. In general, we feel really good about where we are for 2026 and the momentum that we're seeing as we go along the year. Of course, we'll keep the team up to date on our progress. But sitting here today, we feel really good about our momentum in 2026.

Thanks so much for the time. Certainly appreciate it. Best of luck.

Thank you. Thank you, David.

And with no further questions in queue, I will now hand the call back over to CEO Greg Henderson for closing remarks.

All right. Well, thank you all for joining us today. I just want to close by first thanking our global teams. As we mentioned, we had a strong Q4 and good progress to our goals in 25. And we're confident in our momentum into 26, as Abhi just said. So thank you for joining us. We look forward to seeing many of you in person as you join us at our Investor Day on May 14th in New York. So thank you very much.
