Thank you, Rhonda, and good afternoon, everyone. And thank you for joining us. This is my first solo earnings call as CEO. And as I approach nearly six months in a row, I remain very energized by the opportunity ahead of us. We've spent significant time across our global sites, meeting with employees, customers, and partners, and have developed an even deeper connection in the strengths of our team, our strategic position, and have refined our long-term growth strategy and vision which I now call UCT 3.0. I want to thank our employees worldwide for their focus, resilience, and commitment to operational execution during this transition their dedication to our customers and to continuous innovation and improvement is fundamental to our performance and it positions us well as we enter a new phase of AI technology driven industrial growth where speed scale and execution will become defining advantages for long-term winners like UCT. As you have heard recently from our customers and their customers, we're no longer preparing for a semiconductor recovery. We're entering a structural expansion of V4FAB equipment driven by AI infrastructure and physical AI demand. The long-term outlook for the semiconductor market remains very strong. Industry projections now suggest the market could reach $1 trillion in annual revenue of semiconductors by 2027, possibly earlier, which is significantly ahead of prior expectations. What we are witnessing is not a normal cyclical upterm, it is an AI technology inflection. The center of gravity has shift from consumer electronics to AI infrastructure, physical AI, autonomous driving, and other AI applications. The evolving AI roadmap from generative AI to physical and agentic AI and ultimately artificial general intelligence or AGI is driving greater end customer confidence and accelerating investment in AI infrastructure. Stakeholders across the AI ecosystem are investing to support growing AI and market demand. Rising device complexity is accelerating wafer fab equipment spending as leading aid fabs deploy new materials like molyderum and new structures such as gate all around and high bandwidth memory. These technologies require tight integrated solutions across deposition and removal with increased depth edge capacity intensity, which provide a tremendous growth opportunity for UCT. All these market drivers should lead to a multi-year WFE upterm once wafer fabs address their near term clean room constraints. Our technology co-innovation is tightly aligned to our customers' roadmap. We expect to see strength around edge and deposition, especially ALD and high-precision edge. To support gate around and backside power distribution logic transitions, as well as high bandwidth memory, advanced packaging, and greater than 300 layer NAND in memory. This environment demands innovation velocity and operational agility. This is how UCT is positioned today and will continue to evolve to win and create a sustainable profitable growth. This strategic transformation is what we call UCT 3.0. Ramp readiness is our top priority now. We have been preparing for this moment and this is where UCT has a distinct competitive advantage. Over the past several months, we have been focused on our business to operate with greater responsiveness and sense of urgency, efficiency, and accuracy. Leveraging our global talent and footprint, we're driving operational execution initiatives to ensure we grow as the partner of choice for engineering support, development, and also the manufacturing support. Through facility optimizations over the last several years, we have the capacity in place now to support approximately $3 billion in revenue today, with global utilization currently averaging 65%. Among our worldwide capacity, approximately 50% is currently in Asia, with plans to increase to 60% which is strategically aligned to support our key customers' global manufacturing footprint. As volumes ramp quarter over quarter, we will be focused on improving operating leverage and generating meaningful margin expansion. Will we expect 2026 demand to be second half weighted and increase into 2027? Customers are encouraging us to position capacity ahead of that inflection. Our largest customers are providing extended visibility, enabling us to align capacity and service infrastructure in advance of increased order activity. In parallel, we have identified and addressed product specific supply chain and manufacturing constraint to ensure the readiness for a staff function increase in orders. For UCC to support our long-term goal of a $4 billion annual run rate, only modest incremental cleanroom investment will be required. We do not expect infrastructure-related capacity to be a limiting factor during this cycle, provided we continue to build and retain the skilled workforce required and leverage automation and the lean capabilities to scale capacity efficiently. Having well-planned extra capacity entering a technology inflection of this magnitude is a strategic competitive advantage. This allows us to support customer roadmaps while capturing pull-in and drop-in opportunities and responding rapidly to urgent need and frequent changes that others may struggle to support. In addition to our ramp readiness initiatives, we're also accelerating the design to production cycle, expanding our participation in high-value new product introductions at the leading-edge nodes and strengthening strategic technology integration with our customers. A key enabler of this is our expanded NPX strategy, which is comprised of new product introduction, new product development, and new product transition. Together, they will position UCT to a co-innovate earlier, run faster and manufacturing closer to customers, driving speed, responsiveness, and supply chain resilience at scale. Another important focus area is on digital transformation. By upgrading our systems, processes and data infrastructure with AI compatible solutions, we are further improving operational visibility, shorten cycle times, enhancing productivity and enabling a faster response time to our customers. These digital initiatives set a solid foundation for our multi-year digital transformation drive towards AI-enabled IT infrastructure and business processes to enhance operational agility and continuously improve productivity. In closing, we remain focused on reaching our long-term $4 billion revenue target. Expanding margins over time and delivering durable shareholder value as a strategic co-innovator and manufacturing partner throughout the next cycle of technology inflection. We will now turn the call over to Sherry, who will summarize our first quarter results and update you with our first quarter guidance. I look forward to your questions following the financial summary. Thank you.

Thanks James and good afternoon everyone. Thanks for joining us. In today's discussion I will be referring to non-GAAP numbers only. As James mentioned, we are entering a structural expansion of wafer fab equipment spend driven by AI infrastructure and physical AI demand. I'll now review our fourth quarter and full year results as well as provide our first quarter guidance. For the fourth quarter, total revenue came in at $506.6 million compared to $510 million in the prior quarter. Revenue from products was $442.4 million compared to $445 million last quarter. Services revenue came in at $64.2 million in Q4 compared to $65 million in Q3. For the full year, total revenue was $2.1 billion, roughly flat with 2024 revenue. Due to facility optimization initiatives over the last several years, we have the capacity in place now to support approximately $3 billion in revenue and are currently averaging 65% utilization. We believe that in order for UCT to support a $4 billion annual run rate, only modest incremental clean room investment will be required. We remain focused on aligning workforce capacity with demand while leveraging automation and lean disciplines to drive efficient and scalable growth. Total gross margin for the fourth quarter was 16.1% compared to 17% last quarter. Products gross margin was 14.1% compared to 15.1% in Q3, and services was 29.7% compared to 30% last quarter. Gross margin was impacted in Q4 due to a shift in product mix. Total gross margin for 2025 was 16.5 percent compared to 17.5 percent in the prior year. Margins continue to be influenced by fluctuations in volume, mix, manufacturing region, and related tariffs as well as material and transportation costs, so there will be variances quarter to quarter. As production levels increase sequentially, we expect improved operating leverage and meaningful margin expansion. Operating expenses for the quarter was $56.6 million compared to $57.7 million in Q3. As a percentage of revenue, operating expenses were 11.2 percent versus 11.3 percent last quarter. For the year, operating expense as a percentage of revenue was 11.2 percent compared to 10.6 percent in the prior year. Total operating margin for the quarter came in at 4.9% compared to 5.7% last quarter. Margin from our products division was 3.9% compared to 4.9% and services margin was 12.4% compared to 11.1% in the prior quarter. For the full year, operating margin was 5.3% compared to 6.9% in the prior year. Fourth quarter tax rate came in at 21%, consistent with our expectations. Our mix of earnings between higher and lower tax jurisdictions can cause our rate to fluctuate throughout the year. For 2026, we expect our tax rate to stay in the low 20% range. Based on 45.8 million shares outstanding, earnings per share for the quarter were $0.22 on net income of $10 million. compared to $0.28 on net income of $12.9 million in the prior quarter. For the full year, earnings per share was $1.05 on net income of $47.7 million, compared to $1.44 on net income of $65.2 million in 2024. Turning to the balance sheet, our cash and cash equivalents were $311.8 million, dollars compared to 314.1 million at the end of last quarter cash flow from operations with 8.1 million dollars this quarter compared to breakeven last quarter primarily due to working capital management for the full year cash flow from operations was 65.6 million dollars compared to 65 million in the prior year looking ahead we continue to see a strong structural backdrop for semiconductors, with industry estimates now calling for annual revenue to approximately $1 trillion by 2027, possibly earlier. We continue to execute towards our longer-term $4 billion revenue goal with a focus on expanding margins and generating durable shareholder returns. For the first quarter of 2026, we project total revenue to be between $505 million and $545 million. We expect EPS in the range of $0.18 to $0.34. And with that, I'd like to turn the call over to operator for questions.

Your first question comes from the line of David Charles Xu from Needham, please ask your question.

Hi, good afternoon, thanks for taking my questions. I want to start with your overall view on WFE. Back in January, I believe you talked about probably low to mid-teens WFE growth. I saw your presentation, there's 125 to 135 billion, a projection in the deck, but they're not so sure about your base numbers. Can you give us a little bit better sense of what's your WFE forecast this year? And on a related question, the Q1 guidance looks like, at least on a year-on-year basis, it's at the midpoint of the guidance, it's only up a little bit. So it looks like you may be implying a very, very strong second half pickup. I wonder how the shape of the year could be. Thank you. Hi, Charles.

Let me answer your questions, and then we'll have Sherry come in. So as I explained to you in a meeting conference a month ago, you know, we see the forecast increase week by week. So right now, our review on the overall WFE is bigger than a month ago, so we're looking at 15 to 20 percent year-over-year growth. And in terms of your second question, yes, we do not see probably what you see the year-over-year, quarter-over-quarter from our customers. But we have a big bump from Q3 to Q4. So if you take the average, the increase rate actually is kind of in line with the hour.

Hi, James. So maybe a quick clarification. You said big bump. Basically, you're saying maybe the run rate, for your revenue run rate, you see like September will be a very, very strong pickup from June, maybe from a strong pickup again from September to December. Is that what you were speaking to? Yeah, thanks.

Yeah, I think that you're right. So, let's look forward. We definitely see a step function increase in the second half of 26, and that's where However, we see the over year, and we're very optimistic about the whole year growth.

Maybe I may ask a question about the gross margin. So can you provide a little bit taller, March quarter, what's the implied gross margin expectation under your revenue and the EPS assumptions?

Hey, Charles. This is Brian Harding. I'll cover the margin question for you. Just quickly, yeah, we expect gross margins in Q1 to be roughly the same, maybe slightly up to Q4, and then sequentially up from there through the year.

Thank you.

Your next question comes from the line of Krish Sankar from TD Callen. Please ask your question.

Yeah, I think this is a good question. James had two of them. One is if WFV is going to grow 15 to 20 percent, is it fair to assume you could outgrow that WFV this year? and would your revenues grow sequentially every quarter or is this really more backup data that Q2 is going to be flattish so just trying to figure out if you can outgrow WFE for ultra clean revenues you know this year we see a step function growth and of the WFE so we're very confident you know we will

kind of in line with the WFE growth, and we also see that because we have a well-planned extra capacity that really can address $3 billion. So we'll capture more opportunities, leverage that extra capacity, so we're pretty confident we will be on par with WFE growth or even higher.

And would it be sequentially growing or is it more really like Q3, Q4?

I think that we'll see another already but more staff function in the second half.

Got it, got it. And then a quick follow-up, how much was China as a percentage of revenues last quarter and how do you expect that to grow, especially given that the Chinese semi-cap that customers seem to be doing pretty well?

That's a great question. I think that as you have already heard from our customer, you know, the WFE in China is slattish in 2026. I think because of the worldwide WFE is growing substantially, I think the percentage of the China WFE will be lower. For our business, for the China OEMs, with the also kind of flattish forecast for 2026. So, but overall, it's less than 7% of our overall revenue, so I would not put too much of the emphasize on this.

Got it. Thank you very much.

Your next question is from the line of Edward Young from Oppenheimer. please ask your question.

Hi, James. Thanks for the time. Just wanted to follow up on the gross margin assumption for the upcoming first quarter 26. I think Brian mentioned that you're expecting same or slightly up from third quarter. So just wondering what's driving that? Why aren't you seeing more operating leverage from that, and can you maybe talk a little bit more in detail about the mix issue that you saw in the fourth quarter?

Yeah, I think that I will answer that, and now maybe Brian can say, so overall, I really see, as I said, you know, we're running at 65% of the utilization rate today, and we'll see definitely the demand is growing quarter by quarter. So by the end of 2026, we definitely see a much higher utilization rate. That will naturally expand our margin profile. And also, we're keeping very disciplined operation cadence, so we will not grow the OPEX and IDL as the revenue grow. So, that will also – that discipline will also give us a margin expansion of opportunities. And Brian, maybe you want to talk more on the model standpoint.

Just looking at Q3 to Q4, first off, Ed, we – in Q3, we did have a favorable product mix that didn't repeat again in Q4, and so – and our margins do continue to fluctuate with volume and mix and manufacturing regions as well as tariffs and material transportation A number of things impact our margins quarter to quarter. And going forward into Q1, I did say that we expect Q4 and Q1 to be roughly in line, maybe slightly better in Q1. But then as volumes come in, as James mentioned, in Q2, Q3, and Q4, we expect sequential margin expansion in a meaningful way. Okay.

And I mean, this is a tough question to answer, but, you know, obviously a lot of excitement around what's happening in memory, and that's a business that in the prior peak was $900 million in revenue for you. It's down about $300 million from that peak. So I would imagine that would have some significant upside as well. So, James, when you think about, I guess, this memory cycle, So, you know, what's your feeling in terms of, you know, how much longer it could go in terms of the strength on the upside and, you know, what are the sort of parameters we should be watching out for in terms of the slope of that upcycle and the duration of that upcycle? Thank you.

Thank you. Adam, this is a great question. The thing that you hear from our customer's customer, right? And so, some of them are mentioning that the shortage will last until the 2028. And we see that, you know, they – all three of them, Micron, Samsung, and SK, they are really investing on Greenfield. Will they continue to convert existing fab to really kind of address immediate demand? So, we really see this as a multi-year for the memory segment. And also, if you look at the end market demand, HBM will compromise the nameplate, the capacity in the DRAMs factories, so you almost need more WFPE investment to compensate that focus on the HVM capacity expansion, will they still try to address the unbalanced demand of supply in the regular DRAM market? And also, I think that if you look at the NAND, you still see that upgrade from the 2XX to 3XX and 4XX, so that will continue. You heard LAM is talking about that $40 billion over multiple years of NAND upgrade capacity and investment, and they also mentioned that they're going to modify that model, seeing the demand even for the ESSD, for example. So I think that overall, we really believe this is a multi-year growth for the NAND and customer are talking about, for the AI specific memory, they see a 22% CAGR or 2 to 3x CAGR compared to the regular memory market. That's very helpful.

Last question comes from the line of Christian Fraub from CAGR Helm. Please ask your question.

Great. Thanks for taking my question. So, James, with the 65% utilization rate in your recent, you know, facility optimization over the last year and a half or two years, you know, how should we be thinking about What utilization rate or what type of order visibility would be required in essence the billion dollars worth of capacity that we have today?

Yeah, I think that, you know, what we see today, Kristen, is that week by week, we see a drop-in forecast, so we're very optimistic from the run rate, quarterly run rate standpoint, we'll fill that capacity very quickly, especially we're actually shifting our focus to Asian manufacturing, you know, it's kind of in line with our customers' global manufacturing strategy, so very soon you will see our Asian factory will fail completely, and that will eventually represent 60% of our global capacity, it will match the customer's manufacturing footprint. So with the increasing utilization, with heavy-weighted Asian manufacturing, we'll see really the positive on our margin profile.

Margin profile, understanding utilization rates having an impact, but as your customers then begin to materially increase, you know, wafer starts per month, naturally, your services business, which is 21, when that mix of revenue was larger, you know, in a 29% gross margin, plus or minus, naturally kind of drives gross margins there without any material increase in product gross margin. Are you thinking about that, Ray?

Okay, so I think that, yeah, so I guess the question is what is the growth on a service business? We see double-digit growth in 2026. Again, it's also weighted in the second half when our leading-age Foundry Logic customers run up their factories in US. We definitely see we're well positioned for that U.S. boundary logic lamp our current customer we're serving.

Thank you.

Thank you.

There are no further questions at this time. I would now like to turn the call back to James Hsiao for closing comments. Sir, please go ahead.

Thank you for joining us today. This concludes our earnings call.

Ladies and gentlemen, this concludes today's conference call. Thank you very much for your participation. You may now disconnect.
