Welcome, everyone, and thank you for joining us on today's conference call. As announced in our press release earlier today, first quarter revenue grew 22% year-over-year and above seasonal 3.5% sequentially. This growth highlights a solid demand recovery and momentum we are seeing across our key focus areas of automotive in this field and the AI server-related applications. In fact, this quarter is the sixth consecutive quarter of double-digit year-over-year growth and the highest percentage increase since fourth quarter of 2021. Revenue in Europe led growth as we continue to benefit from increased opportunities and orders from automotive customers, as well as improved demand cross-broad industrial applications. Additionally, gross margin improves 70 basis points sequentially due mainly to higher revenue contribution from automotive and industrial markets, which totaled 44% of product revenue combined with improving utilization. Notably, we delivered an over 100% year-over-year increase in quarterly earnings, clearly demonstrating the operating leverage in our model. After formally releasing our three-year interim financial target earlier this year, which includes reaching $2 billion in annual revenue, $700 million in gross profit, and over $4 in non-GET EPS, this quarter was a great first step toward executing on these goals. Content expansion, design-win momentum, and a new product introduction will continue to be the cornerstone of a growth initiative combined with increased manufacturing and cost efficiency to further address margin expansion. With that, let me now turn the call over to Brett to discuss our first quarter financial results as well as our second quarter

guidance in more detail. Thanks, Gary, and good afternoon, everyone. Revenue for the first quarter 2026 was $405.5 million, an increase of 22.1% over the $332.1 million in the first quarter 2025, and up to 3.5% compared to $391.6 million in the fourth quarter 2025. Gross profit for the first quarter was $128.8 million, or 31.8% of revenue, compared to $104.7 million, or 31.5% of revenue in the prior year quarter, and $121.9 million, or 31.1% of revenue in the prior quarter. GAP operating expenses for the first quarter were $109 million, or 26.9% of revenue, and on a non-GAAP basis, we're $103.9 million, or 25.6% of revenue, which excludes $3.9 million amortization of acquisition-related intangible asset costs and $1.1 million of board and officer retirement expense. This compares to GAAP operating expenses in the first quarter, 2025, of $103.4 million, or 31.1% of revenue, and $108.7 million or 27.8% of revenue in the prior quarter. Non-GAAP operating expenses in the prior quarter were $104 million or 26.6% of revenue. Total other income amounted to approximately $2.7 million for the quarter, consisting of $5.4 million in interest income, $2.5 million in unrealized gain on investments, $0.1 million in other income, offset by $3.4 million in foreign currency losses, $1.2 million of impairment loss of equity investment, and $0.7 million in interest expense. Income before taxes, equity and net earnings of equity investments and non-controlling interest in the first quarter, 2026, was $22.4 million, compared to a loss of $2.8 million in the prior year period and $16.8 million in the previous quarter. Turning to income taxes, our effective income tax rate for the first quarter was approximately 19.9%. For 2026, we continue to expect the tax rate for the full year to remain at approximately 18 percent, plus or minus 3 percent. Gap net income for the first quarter was $15 million, or $0.32 per diluted share, compared to a net loss of $4.4 million, or a loss of $0.10 per diluted share in the prior year quarter, and net income of $10.2 million, or $0.22 per diluted share last quarter. The share count used to compute gap income per share for the first quarter of 2026 was 46.1 million shares. Non-GAAP adjusted net income in the first quarter was $19.8 million, or 43 cents per diluted share, which excluded net of tax, $3.2 million of acquisition-related and tangible asset costs, $0.9 million in board officer retirement expense and $0.7 million of loss on investment. This compares to non-GAAP adjusted net income of $8.8 million or $0.19 per diluted share in the first quarter 2025 and $15.7 million or $0.34 per diluted share in the prior quarter. Excluding non-cash share-based compensation expense of $6 million for the first quarter net of tax, both GAAP net income and non-GAAP adjusted net income would have increased by $0.13 per share. EBITDA for the first quarter was $49.4 million, or 12.2% of revenue, compared to $26.2 million, or 7.9% of revenue in the prior year period and $41.9 million or 10.7% of revenue in the prior quarter. We have included in our earnings release a reconciliation of GAAP net income to non-GAAP adjusted net income and GAAP net income which provides additional details. Cash flow provided by operations was $64.3 million for the first quarter, a $26.2 million increase from the $38.1 million in the prior quarter. Free cash flow was $32.4 million, a $20 million increase over the fourth quarter, and included $31.9 million of capital expenditures. Net cash flow was a positive $26.9 million despite the higher CapEx spending compared to last quarter. turning to the balance sheet at the end of first quarter cash cash equivalents restricted cash plus short-term investments totaled approximately 409 million dollars working capital was approximately 891 million dollars in total debt including long-term and short-term was approximately 55 million in terms of inventory at the end of the first quarter total inventory days were approximately 157 as compared to 161 last quarter, and down approximately 30 days from 187 days in the year-ago quarter. Finished goods inventory days were 55 compared to 59 days last quarter. Total inventory dollars increased $21.2 million from the prior quarter to $492.8 million, consisting of a $24 million increase in raw materials, a $0.5 million increase in work and process, and a $3.3 million decrease in the finished goods. Capital expenditures on a cash basis were $31.9 million for the first quarter or 7.9% of revenue, which is within our targeted annualized range of 5% to 9% of revenue. Now turning to our outlook. As you may have noticed in our press release, we have refined the presentation of our guidance to help simplify the information provided, while also aligning to the three-year financial targets we've introduced last quarter. That said, for the second quarter, we expect revenue to be approximately $435 million, plus or minus 3%. At the midpoint, this represents an 18.8% increase year over year. and a 7.3% increase sequentially, which will be the sixth consecutive quarter of double-digit year-over-year growth and another quarter of above-seasonal sequential growth. GAP gross margin is expected to be 32.8%, plus or minus 1%. Non-GAP adjusted EPS is expected to be 60 cents, plus or minus 10 cents. With that said, I will now turn the call over to Emily Yang.

Thank you, Brad, and good afternoon. As Gary and Brad mentioned, revenue in the first quarter was at the high end of our guidance range, up 3.5% sequentially and above our typical seasonality of down 5%. This growth was mainly driven by strong demand in Europe, followed by Asia. Year over year, first quarter revenue increased 22%. Our global POS increased sequentially, and our channel inventory decreased again this quarter, both in dollars and in weeks, which will add them 11 to 14 weeks. We also continue to benefit from the market supply disruption. We remain strategically selective and focus on long-term sustainable business and demand creation. Looking at global sales in the first quarter, Asia represented 77% of revenue, Europe 14%, and North America 9%. In terms of our end market, industrial was 24% of DIOS product revenue, automotive 20%, computing 26%, consumer 17%, and communication 13% of product revenue. Our automotive industrial revenue combined was 44% of product revenue, which was a two-percentage point increase compared to last quarter, largely due to stronger demand in Europe. Now let me review the end market in greater detail. Starting with automotive market, revenue grew 3.8% sequentially and over 32% year-over-year. Overall demand was strong in the quarter, and visibility continues to improve. We are encouraged by the breadth and the depth of our automotive design wins across all focus areas, including connected driving, comfort style safety, and electrification. With an expanding automotive grid portfolio and strong engagements with OEM and Tier 1 customers, We are well positioned to benefit from the increase in dollar content per vehicle. In terms of design wins, we are seeing strong momentum for interface and voltage level shifter ICs across ADAP, telematics, and infotainment platforms. With multiple customer wins, ESD and bidirectional protection devices, including protection for automotive Ethernet and in-vehicle networks, are being designed into next-generation communication platforms and body control modules. Our portfolio of automotive-grade discrete products, including switching diodes, rectifiers, and protection devices, continue to enable reliable data and power paths. We are also securing increased adoption of power protection, power management, and control solutions across safety-critical systems and advanced lighting. Our ideal diode controllers are also seeing strong demand in reverse battery protection power trees, and our precision current limited power switching are gaining traction for protected ECU power wheels. We're also receiving solid demand for our low IQ LDOs in MCU power supplies, and our brushed DC motor drive products experience significant growth, particularly in automotive lighting, cooling, and motor applications. And our 40-AVOL major LED drivers are gaining traction in dynamic real lighting applications, enabling adaptive, signaling, and distinctive vehicle designs. Additionally, our silicon carbide MOSFETs in innovative topside cooling package are gaining momentum in traction inverters, onboarding chargers, and high-voltage DC-DC converters, while our ultra-low VCE bipolar devices continue to win designs in battery management systems and vehicle radars. Turning to industrial market, revenue grew to 24% of product revenue from 22% last quarter, representing a 13.2% quarter-over-quarter growth and over 31% year-over-year. We have begun to see solid demand recovery in Europe, followed by North America and Asia. Much of this strength in demand is being driven by AI infrastructures, and we expect this momentum will continue throughout the year. Specifically, AI surfer power supply units, our bipolar junction transistors portfolio has been winning designs and our hall sensors are being used in brushless DC fan applications for thermal management. Additionally, our rectifying battery backup units are enabling hot swap functionality and supporting the scalable resiliency power architecture required by AI surfers. We're also seeing broad market recovery across multiple applications like factory automation and medical equipment. From a design point of view, we are achieving increasing momentum across power, sensing, and imaging applications driven by the automation and inspection systems. XCM 650-volt silicon-copy diodes continue to gain traction in industrial power applications, supporting higher efficiency and power density requirements. Also during the quarter, our low IQLDL regulators receive solid demand for power tools and industrial fan applications, supporting energy efficiency and battery power designs. And our LED drivers continue to gain traction in intelligent LED lighting applications for smart infrastructure and enterprise environments. Also in industrial, our voltage reference devices receive strong demand from a variety of industrial power supply applications where accuracy and stability are essential. Our AOI contact image sensor products also achieve multiple design aims across inspection-related applications, including IC inspection, battery film inspection, glass inspection, as well as digital check and card scanners. In the computing market, although revenue decreased 3.7% to 26% of the product revenue this quarter, revenue grew year-over-year over 21%. During the quarter, we continue to see strong demand across AI server and data center applications. For the other applications like Novo and Motherboards, we saw demand moderate downward due to the overall software market for these applications combined with a memory shortage in high performance computing and data infrastructures key focus areas remain power management protection connectivity timing and signal integrity high power transcend protection products are being designed into surfer possible power rail architectures delivering ultra high surge protection for mission critical power wheels. Our supervisory reset IC and 5-volt low RDS on switches are seeing strong demand across data center and SSD applications. Additionally, our ISL portfolios, including voltage level shifters for FTI, UR, and GPIOs, are increasingly being utilized in surfers, AI surfers, and workstations, with designs at leading hyperscale and AI customers. And our PCIe 6.0, 7.0 MUX buffers are also seeing adoption across multiple AI surfer platforms. As process migration-driven SOCIO voltage lower, eUSB adoptions continue to accelerate as design-in and design-wings for eUSB repeaters have become widespread across major PC OEMs and ODMs. Dio's p-channel MOSFETs are being designed into desktop platforms for low-switch applications, while our OCP power switches continue to see solid demand in 15-watt source paths for USB power delivery ports in both desktop and docking stations. Our 20-volt, high-performance, low-noise LDOs also continue to gain traction in PC platforms, reflecting rapid design wing conversion. Additionally, in computing, our TVS protection devices have been widely adopted in USB Power Delivery 3 and Able docking platforms, providing robust Transcend and ESD protection. And our USB power delivery sync switch are seeing strong demand in multi-port USB power delivery systems using laptops, supporting high power density and fast charging requirements. In the consumer market, revenue increased 3.8% sequentially and over 26% year-over-year. We continue to see steady demand across personal gaming devices, charging, and home applications. Rectifiers, Zener diodes, and SuperVari rectifiers are gaining adoption in SSDs, tablets, and mini-consumer computers, supporting efficiency, power conversion, and protection in space-constrained designs. Dios USB power delivery controllers and PWM controllers also continue to see growth in the consumer charging market, driven by fast charging adoption and high power requirements. Additionally, our LED drivers are winning designs in household appliances, enabling long lifetime and low-power consumption, while our high-performance boost LED controllers are gaining traction in smart home lighting applications. Lastly, in the communication market, revenue increased 3.8% sequentially and over 17% year-over-year. Growth in data traffic and bandwidth demand is driving enhancement in data center networking applications, increasing adoption of high-efficiency rectification solutions. Dio's SuperBerry rectifier products are gaining momentum, supporting reliable device connectivity in high-speed network equipment. In parallel, our crystal oscillators and ultra-low jitter timing solutions are seeing strong traction in smart NIC cards and networking modules, where systems are becoming smaller and power dense. Our recently introduced ultra-low RDSR CSP MOSFETs are targeting battery protection and power management applications. These devices have been designed in by smartphone customers globally. Our battery fats continue to gain traction in battery-managed systems as demand increases for more power efficiency and feature-rich mobile devices. Complementing to this design, high PSRR, LDOs, level shifters, and dataline protection devices are also seeing strong momentum across smartphone applications. In the wireless infrastructure, our 60-volt buck converters are being designed into RF power applications, including base stations, radar systems, and other high-power wireless platforms. In summary, we have started out 2026 with strong growth momentum across our key focus areas of automotive, industrial, and AI server-related applications. Additionally, we are benefiting from ongoing demand improvement in both the automotive and industrial markets, which should continue to serve as a tailwind to our near-term growth. And when combined, our ongoing margin improvement will well align to deliver increasing earnings and cash flows towards the achievement of our three-year financial goals. With that, we now open the floor to questions. Operator.

We will now begin the question and answer session. To ask a question, you may press star, then 1 on your telephone keypad. If you are using a speakerphone, please pick up your handset before pressing the keys. If at any time your question has been addressed and you would like to withdraw your question, please press star, then 2. At this time, we will pause momentarily to assemble our roster. Our first question today is from Tristan Guerra with Baird. Please go ahead.

Hi, good afternoon. I wanted to understand better the implications of tightening lead times on customer requalifications. Is that helping as people are getting more concerned about securing capacity for 27? And what's your timing assumption as to when those requalification in analog product happen?

Hi, Tristan. This is Emily. During the constrained supply market situation, customers are always more willing for qualifications, especially with a guarantee of a long-term supply, right? So definitely it's beneficial. Overall, we're still going through a lot of process qualification, improving the technology with our internal factories. I would say the progress is progressing well, but it's still going to take some time for us to ramp up more because the qualification of process does take time. But I would say all in all, we are on the right track and right direction.

Okay, great. And then just two quick follow-ups, if I may. Based on your commentary, when do you think that you could get to the point where utilization rates are roughly the same, or at least, you know, all of your fabs are at normalized utilization rates? You know, is that kind of a late 27 dynamic, or do we need to wait later? And then the second one, you touched a bit on the call about traction in data center with your product. I wanted to know how you're approaching the 800 volt opportunity in data center. There's a lot of very high voltage regulators, you know, in each tray, just wanted to understand better, you know, how you see that opportunity going forward. Thank you. Yeah, I think Tristan, I think I'm going to

answer the question, the first question first, you know, and I know we are, as you know, we have been starting to ship the product produced from those two-way verified in Scotland and South Portland to our key customers since last year. And then we're continuing to improve the loading in the next couple of years, right? And as Emily mentioned about the qualification, that takes some time, especially on the customer side, even though during the shortest period, customer has shortened their qualification cycle, try to adapt more of our product. And it's good, but it takes some time. I would say probably 2027, 2028, you can see much more improvement on this utilization on those two wafer fets. But the rest of wafer fets that we have are pretty good loading at this moment. And at the back end, we're almost fully loaded at this moment. For the second question regarding for the 800-volt platform, right? And I think, you know, we're positioned on this kind of, you know, technology in the place. We have our Silicon Carbine MOSFET ready for that, along with analog and discrete device, so we can provide a very good solution to customer media at this moment.

Yeah, so Tristan, let me add a little bit. You know, with the 800 volt, especially on the AI power system or power supply side, We actually see, you know, the power supply unit as one opportunity. We also see the battery backup unit with some of the others, right? So we definitely see across the board really, really good opportunity, you know, other than silicon carbide, you know, and the diodes as well as the MOSFET. We also see a lot of, you know, isolation opportunities. We see sensors. We see some of the power rail protection as well as some of the other. analog and discrete. So I would say all in all, it's actually very positive. So there's still a lot of potential for us to continue to expand. We also focus on some of the new product introduction that we'll share in the future. So we are very, very excited for this opportunity, and we definitely will continue to pursue the new sockets that are in front of us.

Great. Thank you very much. Thank you, Tristan.

The next question is from William Stein with Truist Securities. Please go ahead.

Thanks for taking my questions. First, I'm hoping you can help us understand your exposure to AI data centers across N markets. I think you've got some in compute and some in comms. Can you first just make sure I'm correct on that, that it's split across N markets, and then maybe give us an approximate sizing or percentage of total revenue in that end market?

Yeah, yeah, sure, Will. This is Emily. So overall, we see that AI is a whole ecosystem. It's not just related to AI surfer, right? So earlier I talked about power supply. This is actually under industrial. We're definitely seeing huge potentials overall in this area. You know, we talk about, you know, networking, whether it's the networking switchings or routers. This is the other area that we've seen a lot of expansion overall. Within the networking, I think I mentioned maybe earlier about optical modules, right? So this is also driven by the AI. So I would say all in all, there's multiple areas, not just in the compute, that we've seen AI-related applications.

But we don't have a sort of sizing of that?

Sizing. So I would say, you know, other than the AI surfer that we've seen, you know, a lot of ramp up already, which will continue the momentum, we're also seeing very strong on the power supply side with a lot of new opportunities that working to really help to drive to the 800-watt that Tristan questioned earlier, right? So even on the data center as well as a networking area, because that's really the backbone of everything, we're also seeing really good momentum driven by some of the big networking companies.

Okay, Karen. Let me get to a couple of others if I can. There's a couple of other areas aside from, you know, data center AI that's capturing investors' attention. One is low-earth orbit satellites. Another one is humanoid robotics. Can you talk to your exposure to these markets? Do you have anything in either of those two?

Yeah, I think human rights robotics definitely is a key interest. The reason we haven't really talked a lot, because the volume is still pending to RAM, but all in all, we're actually seeing a lot of similarities. I mean, on top of that, right, if you really think about the automotives, are there a key area driving the voltage to higher and higher, right? So I think all in all, right, on the robotic side, right, other than, you know, the power related, we're also seeing a lot of, for example, the joint movements, right, with a lot of requirements on the MOSFET, on the discrete area, a lot of power management as well. So I would say all in all, that's actually combined everything. It is a very, very big ecosystem that's extending beyond what we're actually seeing at this moment.

And satellite, lower third satellite, anything there?

Oh, for the satellite, yeah. I think we are definitely engaging with a lot of customers working in this area. We probably can share a little bit more in the future.

I'll end it there. Thanks so much.

Thank you. Again, if you have a question, please press star, then one. The next question is from David Williams with Needham & Company. Please go ahead.

Hey, good afternoon, everyone. Thanks for taking my question, and congrats on the continued progress here. Thank you, David. Maybe first, on the pricing trend, it looks like there was a little bit of pricing pressure in the first quarter, and maybe that's more mixed than market dynamics. But can you talk about maybe what you're seeing in terms of pricing? Are you seeing the typical type of erosion trends, or are we in a tight enough environment here that you can, we'll start to see that maybe flip around and get some pricing power.

Hi, David. This is Emily. You are absolutely right. The Q1, what we see in pricing really, really stabilized, and it's mainly driven by the product mix change. And typically during the constrained supply situation, you actually see the price more stabilized or maybe upward trend, right? So definitely we are seeing that in the overall market across all different end

market segments. Okay, great. And then maybe just secondly, you mentioned Europe, I think, multiple times in the script, probably more than we've heard you talk about in the past. I feel like it's coming off the bottom here. But as you look out across your markets and where things are improving, do you sense that any of the strength is coming from replenishment? Or do You feel like it's real in-demand that's coming through, and this is the inflection that we've kind of been hoping for here.

This is the real demand. You know, if you really refer back to our POS point of sales in distribution, we actually decrease the channel inventory, both in terms of dollars as well as weeks. Usually Q1 is a slower quarter for us. Seasonality-wise, usually about 5%, 6% down. We actually achieved 3.5% up, and this is also reflecting from the POS result as well. It's increased quarter over quarter, right? So what we're seeing is definitely demand's real. We haven't really had the opportunity or seen a restocking behavior going on, both in distribution or our customer base at this moment.

Thanks so much, and best of luck on the quarter.

Thank you.

This concludes our question and answer session. I would like to turn the conference back over to Gary Yu for any closing remarks.
