Key Takeaways

  • Positive Sentiment: Fourth-quarter revenue of $391.6M rose 15% year‑over‑year (full‑year up 13%), driven by strong computing (AI server) demand and double‑digit growth in automotive and industrial, supported by broad design wins and content expansion.
  • Positive Sentiment: Management introduced a three‑year interim target to reach $2.0B revenue with ~ $700M gross profit (35%+ gross margin) and >$4 non‑GAAP EPS, implying ~10.5% revenue CAGR and significant operating leverage if execution and utilization improve.
  • Positive Sentiment: Q1 2026 guidance calls for revenue of ~$395M ±3% (≈19% YoY) and a gross margin around 31.5%, indicating management expects above‑seasonal demand and a fifth consecutive quarter of double‑digit YoY growth.
  • Negative Sentiment: GAAP gross margin slipped to 31.1% in Q4 (from 32.7% a year ago) and management says future margin expansion depends heavily on reducing underutilization/underload costs and improved manufacturing efficiency, which are execution risks.
  • Positive Sentiment: Cash generation strengthened materially — 2025 free cash flow of $137.2M, cash and short‑term investments of ~$382M, and ongoing buybacks (partial use of a $100M program) while capex remained within the 5%–9% target range.

Gary Yu
Gary Yu
President and CEO at Diodes Incorporated

Welcome, everyone, and thank you for joining us on today's conference call. As announced in our press release earlier today, we ended 2025 with fourth quarter revenue growing 15% year-over-year and 13% for the full year, which is the highest level of annual growth since 2021. Additionally, this quarter represent the fourth consecutive quarter of double-digit growth year-over-year, further highlighting the success of our design win initiative and content expansion over the past year. We have continued to see demand improvement across our target market and the geographies, with the most significant growth for the full year driven by a 25% increase in the computing market, primarily for AI server-related applications, as well as double-digit increase in our automotive and industrial end markets.

Gary Yu
Gary Yu
President and CEO at Diodes Incorporated

Also, during the quarter, we began to realize initial improvements in gross margin as product mix benefits from growth in the automotive market, which increased 6% sequentially and then 24% year-over-year. We also remain focused on increasing manufacturing efficiency and minimizing underloading costs over the next few quarters to further drive future margin expansion. As we look to the coming quarter, we anticipate extending our success by delivering above seasonal revenue results and our fifth consecutive quarter of double-digit year-over-year growth. As we look back over this past year and the progress that has been made, I want to take this opportunity to discuss my specific near-term financial targets after having been in the role of President and CEO for the past two quarters.

Gary Yu
Gary Yu
President and CEO at Diodes Incorporated

After reaching $1 billion in revenue in 2017, our next billion-dollar goal is to reach $2.5 billion in revenue and $1 billion in gross profit, or 40% in gross margin. I want to emphasize that we remain committed to achieving these long-term goals. In order to help our investors track our progress toward these goals, today, I'm introducing three-year interim financial targets, which including achieving $2 billion in annual revenue with approximately $700 million in gross profit or 35%+ in gross margin. This is equates to a revenue CAGR of 10.5% and a 15% CAGR on gross profit dollars. Most notable, when taking into account our improved cost structure, we are expecting to deliver over $4 in non-GAAP EPS, which equals to a 50% CAGR over that three-year period.

Gary Yu
Gary Yu
President and CEO at Diodes Incorporated

This interim goal highlights the strong operating leverage in Diodes' financial model and the ability to generate significant earnings, power, and the cash flow on each incremental dollar of revenue growth. As mentioned earlier in my remarks, we continue to prioritize product mix improvements by focusing our sales effort and R&D dollars on our three key focus area of automotive, industrial, and computing for AI-related server application. Content expansion, design win momentum, and a new product introduction will continue to be the cornerstones of our growth initiative, combined with increased manufacturing and cost efficiency to drive margin expansion. With that, let me now turn the call over to Brett to discuss our first quarter and full year financial results, as well as our first quarter guidance in more detail.

Emily Yang
Emily Yang
SVP of Worldwide Sales and Marketing at Diodes Incorporated

Thank you, Brett, and good afternoon. As Gary and Brett mentioned, fourth quarter revenue was up over 15% year-over-year, flat sequentially, and at the high end of our guidance, mainly driven by strong demand in Asia, especially in Taiwan, for the AI server-related computing. Our global POS increased sequentially, led by North America and Europe, followed by Asia. This is a good indication of the overall market recovery in the automotive and industrial markets. Our channel inventory decreased again, both in terms of dollars and weeks, which are now within our normal range of 11-14 weeks. I will also highlight, with the recent supply interruption in the market, we have been strategically supporting key customers on new opportunities and orders. Specifically in the automotive and communication markets, while also further extending our design in momentum across all end markets.

Emily Yang
Emily Yang
SVP of Worldwide Sales and Marketing at Diodes Incorporated

Our key focus remained on building a strong win-win partnership with our customers for the long term. Looking at global sales in the fourth quarter, Asia represented 78% of the revenue, Europe 12%, and North America 10%. In terms of our end markets, industrial was 22% of Diodes' product revenue, automotive 20%, computing 28%, consumer 17%, and communication 13% of the product revenue. Our automotive industrial revenue combined was 42%, which is, one percentage point increase compared to last quarter due to stronger demand in Europe.

Emily Yang
Emily Yang
SVP of Worldwide Sales and Marketing at Diodes Incorporated

In 2025, we introduced over 650 new part numbers, which approximately 40% of this specifically for the automotive market, where we have increased our addressable content to 239 per vehicle from 213 at the end of 2024, and from 160 at the end of 2023. Our content in the AI server applications this year increased to 103 from 90 last year. Now let me review the end markets in greater detail. Starting with automotive market, revenue in the quarter grew 6% sequentially and 20% for the full year, as the inventory situation and overall demand continued to improve. The good news is we have started to see solid bookings with longer visibility on the orders.

Emily Yang
Emily Yang
SVP of Worldwide Sales and Marketing at Diodes Incorporated

Additionally, the supply disruption I mentioned previously is expanding content opportunities for Diodes at key automotive customers. During the quarter, we broadened our content and deepened our design-in momentum across all focus areas, including connected driving, comfort, style, safety, and electrification. Diodes level shifter gained broader adoption in in-vehicle infotainment, ADAS, and zonal control unit platforms, while our timing solution saw additional design wins from PCI Express clock generators, buffers, and low-voltage crystal oscillators supporting high-speed ADAS modules. Complementing this momentum, our USB Power Delivery controllers and DC-DC converters continue to see strong traction across infotainment, charging interfaces, and body electronics, while our Hall effect sensors expanded into new applications, including e-latches, steering locks, and cooling fans. In lighting and motor control applications, we achieved significant wins for multi-channel LED drivers across several next-generation lighting programs.

Demand for our current monitor remains strong in comfort-focused motor systems, such as power seats and power windows, while our LDO solutions continued to ramp in wireless charging and ADAS-related subsystems. Our bipolar junction transistors portfolio also gained momentum with new program wins, supporting actuators and millimeter wave radar systems. Turning to the industrial market, revenue in the quarter was flat sequentially, but increased 13% for the full year. Similar to the automotive market, the inventory situation continues to improve. We are beginning to see overall demand visibility and backlog improvement, and are seeing more rush orders than ever before, which is further indication of the market recovery in 2026. During the quarter, we saw solid momentum across power, sensing, and automation applications. Our LED driver family continued to win designs in traffic signage projects, while current monitor experienced strong demand as power supply unit volumes increased.

Emily Yang
Emily Yang
SVP of Worldwide Sales and Marketing at Diodes Incorporated

Diodes Hall Sensor and DC-DC buck converters also maintained steady growth, driven by expanding use in the fan motors and energy meter platforms. Our SBR product family also remained a key enabler in industrial power, with design wins across power rack and server power manufacturers supporting AI applications. In energy-related applications, our 1,200 V silicon carbide Schottky barrier diodes were designed into next-generation energy storage platforms. Similarly, our gate driver ICs secure new design wins in battery storage inverters, reinforcing our position across industrial electrification and power control infrastructures. In the computing market, although revenue was flat sequentially, we saw the strongest growth in this market for the full year, growing 25% over 2024. The highlight in this market continued to be strong demand across multiple product categories, driven by AI server adoption and data center expansion.

Emily Yang
Emily Yang
SVP of Worldwide Sales and Marketing at Diodes Incorporated

Diodes I2C repeaters, multipliers, and USB switches remain in high demand for server and AI-related server platforms from major global customers. Our DDR MUX product line also experienced robust growth as AI server and data center consumers expanded memory bandwidth to support the accelerated AI workloads. We also achieved strong momentum for our PCI Express 5.0, 6.0 clock solutions, especially as server and notebook OEMs migrate to high-performance architectures optimized for AI systems. In connectivity and power, our USB-C source switches with integrated CC controllers, along with our 20 V low noise LDOs, continue to gain traction, especially in 15 W USB-C power ports for desktop and docking station applications. Additionally, our load power switches saw increased adoption in data center SSD configurations, while our smart load switches capture multiple design wins for notebook power delivery systems.

Emily Yang

SVP of Worldwide Sales and Marketing at Diodes Incorporated

We also secure several design wins for our SBR product in power delivery adapters for the notebook. In the consumer market, revenue was down 5% sequentially and up 8% for the full year. During the quarter, our WLED driver gained momentum in the virtual reality headsets, supporting next generation high brightness display architectures, while our 5 OCP switches expanded in USB and HDMI port protection designs as connectivity requirement increase across personal electronics. Also, our bipolar junction transistor portfolio secure new design wins across home security devices, where our discrete switching components remain essential for reliable sensing and control functions. Lastly, in the communication market, revenue was flat sequentially and up 7% for the full year. We're seeing strong momentum across high speed connectivities and networking applications, driven by AI infrastructures.

Emily Yang

Hey, thanks, everyone, and congrats on the really solid results here and the better outlook.

David Williams

David Williams
David Williams
Equity Research Analyst at Benchmark

Yeah, I guess maybe first, Gary, you gave some pretty aggressive targets there that you've outlined. Can you kind of maybe walk us through the cliffs and takes and maybe you know how you see getting there, maybe just stepping through the trajectory would be helpful. Thank you.

Gary Yu
Gary Yu
President and CEO at Diodes Incorporated

Yes, David, I think that's really, really a very good question. You know, first, I really want to emphasize again, we're still committed to achieving the $1 billion GP long-term goal, right? And, you know, I do believe since the market is still kind of dynamic and the interim target of a $2 billion revenue is an important milestone for investor to understand and modeling how and when we are going to achieve the, our long-term $1 billion GP target. So as in my speech, you know, continue to drive and gaining share in the three key end market segment, like automotive, industrial, and AI server-related application, and also continue to improve cost structure and the product mix enhancement.

Gary Yu
Gary Yu
President and CEO at Diodes Incorporated

That the $2 billion, you know, represent 10.5% CAGR, with about, like, $700 million gross profit, is about, like, 15% CAGR, and a 35% and plus GP percent will deliver $4 EPS, which equivalent probably 50% CAGR for the three-year period. And also, to make this happen, you know, we are talking about a more than 45% GP flow through for any incremental dollar contribute to our revenue, and that's very important.

David Williams
David Williams
Equity Research Analyst at Benchmark

That's very helpful. So I guess from the gross margin standpoint, very nice fall through. Is that simply just the leverage, or are you seeing some of the operational efficiencies that you've kind of worked on the last several quarters or through the downturn? Is that really beginning to flow through? And then how should we think about the cadence of that gross margin improvement?

Gary Yu
Gary Yu
President and CEO at Diodes Incorporated

Well, actually, you know, that's a very good question, too, 'cause, you know, we have been working a lot to improve our cost structure, you know, including the improving the manufacturing efficiency and the product mix improvement. And the most important, we bring the revenue up, and that's gonna try to help our underloading issue in our manufacturing currently.

David Williams
David Williams
Equity Research Analyst at Benchmark

Great. And just one more, if I may. Just, if you kind of think about the growth trajectory through the year, how should we kind of think about that for the full year?

Gary Yu
Gary Yu
President and CEO at Diodes Incorporated

Well, we usually don't talk about the full year, but I do get a good feeling of the market demand getting much better this year, right? Especially on the key segment that we're focusing on. And as we continue to drive this kind of initiative, including product mix improvement and push more cost reduction and then manufacturing efficiency, as well as to continue to qualify in the PC or process product to our fab. And this will help minimize an underloading cost impact. So overall, the market improvement for 2026 to me is very promising.

Emily Yang
Emily Yang
SVP of Worldwide Sales and Marketing at Diodes Incorporated

Yeah, I think, David, let me just add a little bit, right? So if you look at the Q1 guidance, we actually guided a 19% year-over-year growth, right? So even we don't really guide a whole year guidance, we usually, you know, say, "Hey, usual seasonality." If you just plug in the usual seasonality, it kind of will give you a good estimate for the year, right? So I think you can use that as a reference.

David Williams
David Williams
Equity Research Analyst at Benchmark

Great. Thanks so much.

Operator

Our next question comes from William Stein, from Truist Securities. Please go ahead with your question.

William Stein
William Stein
Managing Director and Senior Analyst at Truist Securities

Great. Thanks for taking my questions, and congrats on the good results. Regarding the new targets, I think you said that's a three-year target, so should we contemplate this interim goal as something you plan to achieve in calendar 2028?

Gary Yu
Gary Yu
President and CEO at Diodes Incorporated

Yeah, definitely, yes. This is why I committed to the board and also committed to the street.

William Stein
William Stein
Managing Director and Senior Analyst at Truist Securities

Great. A couple of others, if I can. The, the delta between your current gross margins and the target that you laid out today, should we think about the majority of that as getting through underutilization charges? Like, is that the major driver of this. I, I think you highlighted a 45% drop through. That doesn't sound like it's sort of normal operating leverage. It sounds like it's an underutilization charge going away. Is that, is that the way we should think about that dynamic from here through 2028?

Gary Yu
Gary Yu
President and CEO at Diodes Incorporated

Yeah, definitely. Underload charge is gonna be the key factor, you know, for our GP percent, and, but that's not the only thing we want to improve, right? Not only the underloading charge, but also want to improve the product mixing, you know, enhancement, and also want to concentrate and focus on high margin segment, like automotive, industrial, and AI-related server. Altogether, will contribute more GP dollars and GP percent.

William Stein
William Stein
Managing Director and Senior Analyst at Truist Securities

Great. One final one, if I can. You have these manufacturing services agreements that I think are coming to an end this year or maybe, maybe they're just diminishing. If you can clarify that for us and help us prepare for any changes that might cause either positive or negative to profitability. Thank you.

Gary Yu
Gary Yu
President and CEO at Diodes Incorporated

Yes, you know, and your assumption is correct, and, you know, and, we cannot disclose too much detail about that, but they are about to actually know about this year. And that's the reason we try to, you know, continue reporting our product and then processing to the manufacturing in our GFAB and SFAB. And so far, the progress quite promising, and we do see that quite a few in key customer already adopt the product produced from those two wafer fab. And, you know, I will say, you know, probably starting from next year, you're gonna see the benefit contributing to our GP percent from those two wafer fab.

William Stein

Hey, thanks for letting me jump back in here.

Gary Yu
Gary Yu
President and CEO at Diodes Incorporated

You're always welcome.

David Williams
David Williams
Equity Research Analyst at Benchmark

Well, you were so efficient answering my first questions, I figured I should throw in a couple of more. But, maybe just on the opportunity with Nexperia or the customer that you discussed earlier, can you maybe size the magnitude of that? And then I know that that has historically been lower margin business. Can you talk maybe about what you're doing to help stabilize the margin and not see the pressure here that you would typically see with that business picking up?

Emily Yang
Emily Yang
SVP of Worldwide Sales and Marketing at Diodes Incorporated

Yeah. So, David, this is Emily, right? So I mentioned this before. Anytime there's a supply interruption, market strategic change direction or anything, is always favorable for Diodes, right? So, you know, definitely we're not interested to pick up a lot of deep commodity business and stuff like that, but we actually use the opportunity to work with the customer to really deepen the relationship and make it really, I would say, beneficial long term for both of the companies, right? So that's pretty much the approach we're taking. So we are using the opportunity to expand our overall portfolio as well as our prime position.

And just one last one. Just kind of thinking about the Lunar holiday coming up in Asia. I know that that is typically drives some seasonality. Are you sidestepping that or are you just not seeing the impact or maybe talking about anything you're doing there to offset that typical weakness?

Yeah, Chinese New Year is pretty standard, right? Definitely there's gonna be some shutdowns and some of the customers as well as taking the break, right? So we actually included all these estimates into our number. But like I mentioned, right, we're definitely seeing a really strong backlog, really strong booking, strong book-to-bill ratio and everything. So that's the reason we actually guided a very strong Q1 estimate guidance to the street. So, you know, like I said, right, we've seen a lot of recovery in the market. Very good indication of the recovery.
