Thank you, Joe. Good morning, everyone. Before discussing this quarter's business performance and outlook, I want to briefly discuss recent organizational changes we announced on October 28. I have taken over as Interim CEO due to Fusen Chen's recent retirement and will continue my existing duties as the Company's Executive Vice President and Chief Financial Officer. Fusen is actively recovering and doing well, and we appreciate everyone's thoughts and concerns. While a search for a permanent successor among external and internal candidates is underway, we are fortunate to have a deep bench of talented leaders in the executive team and an involved Board of Directors who are committed to ensuring the continuity of leadership, stability and strategic focus of the Company. We expect this transition to be seamless and customers can expect continued innovation, global support and strong commitment from Kulicke and Soffa to serve the evolving needs and to enable next-generation devices. I want to thank Fusen for his leadership over the past 9 years. Under his guidance, we pursued meaningful new business opportunities and expanded our market access by securing a foothold in several high-potential technologies. We have also dramatically increased the volume of customer engagements and improved time-to-market execution. In doing so, we have accelerated the growth of our advanced portfolio of solutions, which enabled meaningful share gains in leading-edge logic and has paved the path for additional expansion in DRAM, power semiconductor and advanced dispense. Fusen's legacy is an organization defined by growth, agility and close customer focus. We appreciate that he has agreed to provide advisory support over the coming year and believe his vast experience and industry knowledge will be a useful resource to the company as we extend our leadership in advanced packaging and adapt to industry transitions such as the rise of chiplet architectures and heterogeneous integration. I, along with the entire organization, would like to wish Fusen a happy and healthy retirement. I am confident we will continue to win market share and grow the business over the long term. As all of our end markets are showing signs of improvement, we have recently begun to prepare for higher production while continuing to aggressively drive several exciting technology transitions. Additionally, in my role as Interim CEO, I am grateful to have met many customers in person over the past month and look forward to meeting with many others over the near term. We are fully committed to consistently providing customers with best-in-class capabilities and high-performance solutions they expect from Kulicke and Soffa. Turning to our recent business results. We are encouraged by improved order activity, supported by favorable utilization trends in general semiconductor and memory end markets while we continue to execute on key initiatives. Within our fourth fiscal quarter, we generated revenue of $177.6 million, GAAP earnings per share of $0.12 and non-GAAP earnings per share of $0.28. We remain focused on operational efficiency as we expand our reach within thermocompression, vertical wire, advanced dispense and power semiconductor transitions. From an end market standpoint, utilization rate for high-volume general semiconductor and memory applications continue to improve, while dynamics within the automotive and industrial markets are now showing early improvement. General semiconductor revenue increased by 24% sequentially, driven by technology and capacity needs, which increased thermocompression and ball bonder demand during the September quarter. We estimate utilization rates are currently over 80% for this key end market. Memory has also improved sequentially, similar to general semi in both utilization and revenue. Memory-related revenue increased by nearly 60% sequentially to $24.4 million and was driven predominantly by NAND-related capacity additions. Historically, our memory solutions were tailored for high-density NAND assembly, although we remain closely engaged in supporting advanced packaging transitions within DRAM. We continue to expect the growth in high-performance edge applications like on-device AI or AI on the edge will begin to accelerate this trend. Order hesitation within automotive and industrial has continued into the September quarter with a relatively sharp sequential decline. While the broader automotive market has been softer, we anticipate a sequential improvement during the current December quarter and are pleased to report a more positive outlook through fiscal 2026. As a reminder, we remain an active technology partner, providing many new innovations within power semiconductor, which are supporting long-term transitions within the EV and other clean tech markets. Last, APS has increased by 17% sequentially, which aligns with improving utilization data and more distinctly highlights increased production activity across our high-volume installed base. We are optimistic about fiscal 2026 and remain encouraged by improving end market dynamics along with strong traction we are seeing across our growing set of advanced packaging, advanced dispense and power semiconductor opportunities. Within advanced packaging, we continue to support the industry adoption of advanced thermocompression and vertical wire applications and remain closely engaged with multiple leading customers on these exciting initiatives. First, within fluxless thermocompression or FTC, we continue to directly address the needs of advanced heterogeneous logic applications. We are pleased to see growing demand across our customer base, driven by the increasing capacity needs of IDM, foundry and assembly and test customers. Our operational and supply chain teams are actively preparing for a production ramp through fiscal 2026 as adoption for our FTC process begins to accelerate. Additionally, we are preparing to ship our first HBM system within the current December ending quarter. Within the HBM market, we continue to anticipate advanced thermocompression capabilities such as FTC provide an attractive assembly alternative as bandwidth requirements increase with future HBM standards. On the mobility side of DRAM, we continue to expect on-device AI applications to demand high levels of bandwidth and increase the need for new vertical wire-based assembly over the coming years. This is a great example of how advanced packaging techniques are directly supporting power efficiency, performance and form factor improvements, helping to offset the rising costs of traditional transistor shrink. We remain engaged with a broad group of memory customers who are actively preparing for this transition. Our vertical wire market expectations into fiscal 2026 remain consistent, and we continue to anticipate a shift to higher-volume market production by the end of the year. Longer term, we anticipate stacked DRAM or mobile HBM will continue to grow aggressively with high-volume edge-related applications. Next, with advanced dispense, we are pleased to release our recent dispense system, ACELON during Semiconductor Taiwan in September. ACELON leverages our unique and high-precision dispense capabilities with a highly robust architecture platform, which has been proven in critical production environments. Transitions in many of our end markets are increasing demand for high precision and more capable dispense systems. We continue to receive recurring purchase orders as well as new customer purchase orders for our growing line of advanced dispense systems. Finally, while the current automotive and industrial market remains dynamic, we continue to develop innovative solutions to address increasing levels of assembly complexity surrounding power semiconductor applications. In summary, we continue to expand our market presence on multiple fronts and remain cautiously optimistic as key regions and end markets show signs of cyclical improvement. We are pleased to see ongoing general semiconductor capacity digestion and expansion within our key regions as well as memory technology transitions and pricing improvements, which are all promising indicators that increase our confidence in the outlook. We continue to navigate a uniquely exciting time in semiconductor assembly with the potential to capitalize on a wide set of opportunities in the industry. With that said, I will now provide a brief financial update. My remarks today will refer to GAAP results unless noted. We delivered revenue above guidance, continued to execute on close customer engagements and maintain an ongoing focus on cost control. Gross margins came in at 45.7%, and we delivered $0.28 of non-GAAP earnings. Total operating expense came in at $80.3 million on a GAAP basis and just below $70 million on a non-GAAP basis. We continue to remain focused on operational efficiency while we support a growing set of opportunities. We continue to anticipate non-GAAP operating expenses to be around $70 million over the coming quarters, which provides a strong foundation for operational leverage as demand for our solution ramps. Tax expense came in at $0.3 million, and we continue to anticipate our effective tax rate will remain above 20% over the near term. During the September quarter, we continued our repurchase program and deployed $16.7 million to repurchase 464,000 shares. Over fiscal year 2025, we repurchased 2.4 million shares, representing nearly 5% of shares outstanding for $96.5 million. Looking ahead, end market improvements within general semiconductor and memory are becoming more evident, supported by regional utilization improvement and a strong sequential increase in APS demand. While automotive and industrial was previously expected to create an ongoing headwind into fiscal 2026, we are pleased to now anticipate sequential improvement into the December quarter. For the December quarter, revenue is expected to increase by approximately 7% sequentially to $190 million with gross margins at 47%. Non-GAAP operating expenses are expected to be $71 million with GAAP earnings per share targeted to be $0.18 and non-GAAP earnings per share of $0.33. While we remain focused on production readiness and key growth opportunities, we have also strengthened operational and development efficiencies over the past few quarters. We are confident that these efforts position us to emerge from the extended soft demand period, a leaner and more growth-optimized organization. Today, we're either a dominant incumbent leader or are aggressively taking share in every key market we serve. We continue to ensure our highest potential opportunities are well-resourced and our customer development efforts are on a positive trajectory. Looking into fiscal 2026, we anticipate that half of our incremental growth will stem from technology transitions and share gains in new markets. At the same time, the other portion of sequential growth is increasingly encouraging due to the anticipation of ongoing cyclical recovery over the coming quarters. We look forward to ongoing execution and progress on advanced packaging, advanced dispense and power semiconductor opportunities as we prepare for the broader core market recovery. In closing, we remain focused on executing our strategic priorities, are confident in our capabilities and technology leadership and prepared to navigate the near-term macro environment. This concludes our prepared comments. Operator, please open the call for questions.

Today's first question is coming from Krish Sankar of TD Cowen.

Good luck to Fusen and definitely going to miss him. I have 2 questions left. The first one, it looks like based on your guidance, pretty much sequentially all your 3 segments, general semi, memory and auto industrial should grow. Is that the right way to think about it? And how to think about it into the March quarter and any kind of seasonality effects? And then a follow-up.

Thanks, Krish, and I appreciate your sentiment for Fusen, I will definitely pass it on. As far as the 3 segments are concerned, I think as we said, general semi and memory are actually very strong. Utilization for both is over 80%. Auto and Industrial is still lagging a little bit, but we are very optimistic about it because we do see improvements, and we think there will be sequential growth into Q1. So I think as far as how we want to look at the March quarter, we think March will probably be flat to Q1. So we don't see any seasonality into the March quarter.

Got it. And then as a quick follow-up, one of your Taiwan competitors spoke about their FTC plasma solution for chip-to-wafer has passed final call as being used with a leading foundry. So I'm kind of curious, what is your status there? And do you think they could split the business or you're not in pole position anymore?

Well, Krish, I think we're still the only one at the foundry doing high-volume production, right? I won't comment on our competitors. I mean we were qualified a long time ago. So I think we continue to feel very strongly about our solution. Our solution now has both formic acid and plasma. So it gives the customer a lot more optionality to do it. We have single head, we have dual head. So we think our FTC solution is basically best-in-class, and we feel very, very competitive at the foundry as well as anywhere else we compete against the competitors.

The next question is coming from Charles Shi of Needham & Co.

Lester. You mentioned shipping a system to the HBM customer. I know the team has been working on this for some time, and it’s finally being shipped. This should be positive news for most investors. Could you share more details about this shipment? What is the nature of the shipment and where is it being sent? Additionally, what is the next milestone?

Thanks, Charles. We're shipping the system to a location in the United States, without being too specific. The next milestone is that once it is installed, they will start running wafers through it, and we will be looking for qualification. We hope to share some news a few months after the system has been installed at the customer.

Do you have any insight into which generation of HBM this qualification is targeted at?

I would say it's probably 4E.

Okay. So for the next question, you mentioned growth for fiscal '26. Half of that growth will be from technology transitions and market share gains, while the other half is expected from a cyclical recovery. Could you provide some quantitative details on that? For example, what percentage points do you anticipate will come from each area? Any directional insights would be greatly appreciated.

Sure, Charles. As you know, we don't provide guidance beyond the current quarter. However, we feel very comfortable with the consensus number for fiscal year 2026, which is approximately $730 million to $740 million. As I mentioned earlier, we anticipate that half of the incremental growth will come from technology transitions, such as FTC, vertical wire, advanced dispense, and power semiconductors. The other half should be driven by a cyclical recovery, supported by a high utilization rate, which is currently around 80%.

The next question is coming from Tom Diffely of D.A. Davidson.

Lester, I was wondering if you could talk a little bit more about the NAND market. We're hearing obviously strength in high-bandwidth memory, and that's using up some of the DRAM capacity. But I haven't heard anybody talk about strength or improvements in the NAND markets until you mentioned it earlier today. Maybe just a little more comment on the NAND market.

For sure. What we're observing is very high utilization rates in memory, which are over 80%, about 82% to 83%. We're also noticing an increase in purchase orders in that market, particularly in China. The demand in China is being driven by general semiconductors and memory, with utilization rates close to 90%. That's essentially what we're seeing in the field, Tom.

Okay. You mentioned that there wasn't much typical seasonality, but do you still anticipate an increase in new orders following the Chinese New Year, in line with the usual cycle?

Well, we're actually, again, already seeing orders now into Q2. So I think it'll probably be flat. I think this year, FY '26 probably would be a little more linearity throughout the entire year. So I think, again, I don't see a huge uptick after Chinese New Year, but it'd be nice if it happened.

Yes, I want to agree with your comments about Fusen. I have been following the company for 25 years, and when he took over many years ago, there was a significant improvement in the company's productivity and outlook. I wish him all the best.

Thank you, Tom. Thank you. As I indicated, Fusen transformed Kulicke and Soffa and expanded our portfolio of advanced products. And a big part of this incremental growth from technology transition is due to his vision and his strategy. So we all wish him well in his retirement.

Our next question is coming from Dave Duley of Steelhead Securities.

Please relay my best wishes on retirement to Fusen as well.

We do, Dave.

First question, I think in your slide deck, you talked about increasing market share in the HBM market. Could you just elaborate a little bit further on that? Is that just what you were referring to is shipping an HBM tool for thermocompression bonding? Or is there something else to that commentary?

So Dave, I think actually the slide referred to increasing market share in DRAM, not specifically HBM. As I think I said in my remarks as well as responding to Charles' question, we are going to ship our first HBM machine to a customer in the U.S. for qualification.

Okay. So that commentary is just wrapped around the HBM shipment to a thermocompression bonding tool, nothing else?

Yes. For now, we are very focused on thermocompression in the logic sector, where we are the market leader. However, we are just now starting to enter the HBM market. We are very optimistic because we believe the tool is well suited for HBM. As standards evolve and density increases, we think the tool will perform very well.

Do you think you will be trying to replace a standard thermocompression tool for this customer, or will you be competing against a hybrid tool? How do you see the qualification process unfolding and what are you competing against?

Well, I think we're basically competing against other thermocompression bonders, right? Not so much hybrid for now. I think hybrid still, as we've spoken before, for HBM, hybrid is a little bit off for now. So I think mainly the competition will be other TCB.

Okay. You mentioned vertical wire ramping in 2026. Could you explain why this ramping is happening now? Is it related to a specific handset model or market? Also, can you share your expectations for this new business in 2026?

Sure. Well, I mean, we've been working on vertical wire for a while. And now we've had calls and we have tools at many customers, both in China as well as outside of China. As the calls progress, we believe that the first high-volume production will be in the latter part of CY '26, which means we start shipping tools in the latter part of our fiscal '26, right? So I think that's basically sort of the color around what we think. And as far as our expectations, we still think FY '26 is going to be the beginning. So I think somewhere around the neighborhood of $10 million, and then we think it will ramp significantly in '27 and beyond.

Okay. Do you have any insights regarding your core business, particularly how it relates to unit volume growth in the overall semiconductor market? I'm curious if you can provide any estimates on the growth of units in 2025 or forecasts for unit growth in 2026.

Well, yes, we have used that before, and I think it's probably 5%, 7%. But again, I think what is really giving us confidence is the utilization rate, which is, as I said, over 80% in both memory and general semiconductor and then 80% overall. Also, again, a lot of our core business is in China, and that utilization rate is almost close to 90%.

The next question is coming from Craig Ellis of B. Riley Securities.

Lester, good luck in the role and good luck to Fusen as well with health issues. I wanted to start and admittedly, I missed the first part of the call, but I wanted to start better understanding the dynamics that you're seeing in the memory market. Lester, do you think this is just a steeper slope that you're seeing in memory as utilization and orders have improved? Or is it really just a different timing for what might be a typical seasonal move up in memory ahead of second half build. So the question is really on the trajectory of the recovery that you're seeing.

Currently, memory utilization is very high, and sales are increasing. They are still behind the general semiconductor market. I believe we are in a ramp-up for memory, and this trend will continue into fiscal year 2026.

Yes. And can you talk about the potential for memory in '26 to get back to historic revenue levels? And then because general semi is rebounding and it's doing so against a slightly improved but not significantly improved high-volume PC and smartphone market. What do you think is really driving the improvement in general semi?

I believe the focus remains on smartphones and high-performance computers. It's a cyclical situation. We've experienced around three to four years of a downturn, primarily due to the substantial inventory buildup in 2021 and 2022. I feel we're returning to a more typical cycle, and this marks the start of the recovery that many have been anticipating.

Okay. And then lastly, I think you did mention in prepared remarks that we're not yet seeing any signs of uplift from the auto and industrial market. But as you talk to customers in those end markets, are you getting any indication that they could begin to see an upturn sometime in the first half of calendar '26? Or is it still just very low visibility and an absence of any signs of improvement?

So Craig, when we speak to customers, we sense a certain optimism. While there are still some challenges, the situation has definitely improved significantly. We anticipate our auto industrial revenue will rise sequentially in Q1 compared to Q4. Looking ahead, we do notice that it is lagging a bit behind general semiconductor and memory markets, but we expect it to recover, especially with our customers in Southeast Asia and China. One key point, Craig, is that we are involved in a technology transition in power semiconductors, which is important for cleantech and electric vehicles. Considering all these factors, we believe that fiscal year '26 will be a much stronger year for the auto industrial sector.

At this time, I would like to turn the floor back over to Mr. Elgindy for closing comments.

Thank you, Donna, and thank you all for joining today's call. Over the months, we'll be participating at conferences in New York and Phoenix. As always, please feel free to follow up directly with any additional questions. This concludes today's call. Have a great day, everyone.

Ladies and gentlemen, thank you for your participation. You may now disconnect your lines or log off the webcast. Have a wonderful day.
