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 K&S 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…

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 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 do -- we're 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 -- probably 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. Maybe the first one. You talked about shipping a system to the HBM customer. I know the team has worked on this for a while, and it's finally shipping. So it's definitely going to be good news I think by most of the investors. But kind of wondered if you can provide a little bit more color on this shipment. What's the nature of the shipment? Where -- I mean, as much as you can provide color where you are shipping the system to? And what's the next milestone?

Thanks, Charles. Well, we're shipping the system to the -- somewhere in the United States, right, without being too specific. As far as the next milestone is once it's installed, they're going to start running wafers through it, and we're going to look for qualification. So we hope to get -- 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 maybe the next question, you talked about growth for fiscal '26. Half of that is coming from tech transitions, share gains, the other half from cyclical recovery. But wondering if you can put some quantitative color into that, like how much -- how many percentage points do you think can come from both areas? And any directional -- I mean, hopefully, it can be a little more quantitative that would be great.

Sure, Charles. As you know, we don't guide beyond the quarter. But I think we're very comfortable with the -- for FY '26, we're very comfortable with the consensus number, which I believe is around $730 million, $740 million. And then again, as I said in my remarks and as you just repeated, we think half the incremental growth will be from technology transition like FTC, like vertical wire, like advanced dispense as well as power semiconductor. And then the other one would be from the cyclical recovery led by the very high utilization rate, which we see out there, which is about 80% right now.

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. I mean I think we -- what we're seeing is we're seeing very high utilization rates in memory. It's over 80%, about 82%, 83%. We're also seeing, I guess, purchase orders increasing in that market as well, particularly in China. Again, China itself, it's driven by general semi and memory and China utilization is actually close to 90%. So that's basically what we're seeing in the field, Tom.

Okay. And would you still -- you said there wasn't much in the way of normal seasonality, but would you still expect more of a ramp to happen post Chinese New Year kind of the normal cycle as far as incoming new orders?

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. And I do want to echo your comments on Fusen. I've been covering the company on and off for 25 years. And when he came in several -- many years ago, there was really a sea change in the productivity of the company and the outlook of the company. So I wish him all the best.

Thank you, Tom. Thank you. As I indicated, Fusen transformed K&S 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.

[Operator Instructions] 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 -- as you know, we started our thermocompression focus on logic. We are the market leader in logic for thermocompression. But again, we're just entering the HBM market now. But we're very optimistic. We believe the tool is very well suited to HBM. And we think as standards change and as well as density increases, I think the tool -- the [ Fluxless ] thermocompression compression tool will do really well.

Now do you think at this customer, you'll be trying to displace a Fluxless -- a standard thermocompression tool? Or will you be -- are you up against a hybrid tool? Or what do you think kind of the -- how this unfolds as far as the qualification goes and what you're 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. And then you mentioned vertical wire ramping in the -- I think, in the back -- in 2026. Could you just elaborate a little bit more on what exact -- why is that ramping now? Is it tied to specific handset model or some end market? And then maybe help us understand what expectations you have for that 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. And do you have -- as far as your core business goes, usually, it's somewhat tied to unit volume growth in the general semi market. I was just wondering if you had an idea about how fast units are growing in 2025 or a prediction 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.

Well, as -- so Craig, I think right now, memory utilization is very high. I mean sales are increasing there. They're still obviously lagging general semi. So I think right now, I do think this is a ramp in memory, and it will continue into FY '26.

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?

Well, I think it's still smartphone and high-performance computer, right? I mean it's cyclical. I think for a long time, we've -- as you know, we've had almost 3 plus 4 years of a downturn, right? And this is the digestion of the tremendous amount of inventory that was built up in '21, '22. So I think actually, this is almost back to a normal cycle, right? And it is the beginning of the recovery, which I think we've all been waiting for.

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, I think when we talk to customers, we actually get a sense of optimism, right? I think while there is still a little bit of headwinds, it's definitely improved significantly. And we expect our auto industrial revenue to increase sequentially in Q1 from Q4, right? And then I think going forward, we do see -- it's lagging general semi and memory a little bit, but we do see it coming back, right, particularly maybe our customers in Southeast Asia as well as in China. So -- and one thing I think, Craig, as you know, we are sort of involved in sort of a technology transition on power semi, which is basically, again, for cleantech as well as for EV. So I think with all those factors, we definitely think FY '26 will be a much better year for auto industrial.

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