Greetings. Welcome to the Aehr Test Systems Third Quarter Fiscal 20 24 Financial Results Call. At this time, all participants are in a listen only mode. A question and answer session will follow the formal presentation. Please note this conference is being recorded.

Operator

I will now turn the conference over to your host, Jim Byers at MKR Investor Relations. You may begin.

Speaker 1

Thank you, operator. Good afternoon, and welcome to Aehr Test Systems' 3rd quarter fiscal 2024 financial results conference call. With me on today's call are Aehr Test Systems' President and Chief Executive Officer, Gain Erickson and Chief Financial Officer, Chris Hsu. Before I turn the call over to Dane and Chris, I'd like to cover a few quick items. This afternoon, right after the market closed, Aehr Test issued a press release announcing fiscal 2024 Q3 financial results.

Speaker 1

That release is available on the company's website at air.com. This call is being broadcast live over the Internet for all interested parties, and the webcast will be archived on the Investor Relations page of the company's website. I'd like to remind everyone that on today's call, management will be making forward looking statements that are based on current information and estimates and are subject to a number of risks and uncertainties that could cause actual results to differ materially from those in the forward looking statements. These factors are discussed in the company's most recent periodic and current reports filed with the SEC. These forward looking statements, including guidance provided during today's call, are only valid as of this date, and Aehr Test Systems undertakes no obligation to update the forward looking statements.

Speaker 1

And now I'd like to turn the conference call over to Dane Erickson, President and CEO.

Speaker 2

Thanks, Jim. Good afternoon, everyone, and welcome to our Q3 fiscal 'twenty four earnings call. Thanks for joining us today. I'll start with a quick summary of the quarter and spend some time to address what seeing across key markets there is addressing for our semiconductor wafer level test and burn in systems. We've actually had a lot of questions in the last couple of weeks and also feedback coming in.

Speaker 2

So our plan is to take some time to cover all of the markets that we're addressing, and then we'll open it up for questions. As we discussed in our Q2 earnings call, we've seen several pushouts of forecasted orders by current and new customers that impacted our fiscal year revenues. We believe that this was due to 2 key factors. There's clearly softness in the overall semiconductor capital spending, particularly in automotive applications, as related to a glut in inventory driving down near term orders to these companies that has caused them to push out capital spending and drive cost reductions. Multiple companies, including the companies we had expected orders from, have publicly discussed inventory related headwinds in their public earnings calls and press releases.

Speaker 2

In addition, we've seen specific shifts in order timing of our equipment used for wafer level test and burn in of silicon carbide power semiconductors used in electric vehicles. In just the last 2 weeks of the quarter, we saw delays in orders for silicon carbide systems with customer requested ship dates within the quarter as well as a last minute push out by a customer of a system in our backlog. And that effect of this was a significant shift in revenues out of the 3rd 4th quarters. Until this time, we've been hearing from those customers that their silicon carbide based capital investments were not being impacted. It's now clear that the recent overall softness in semiconductors and the impact of shifts in electric vehicle introductions and ramps are impacting our bookings and revenue forecasts more than we understood only 2 months ago at our last earnings call.

Speaker 2

We now expect this to last for another quarter or 2 before the orders resume based on the latest roll up of direct forecast from over a dozen silicon carbide companies. Due to this, last month, we revised our guidance for our fiscal 2024 year end ending May 31, 2020 4 to be greater than $65,000,000 in total revenue and net income of at least $11,000,000 which we're reiterating today. We still expect to finish this year with annual revenues that are near or above our full year record. Our discussions with customers indicate that the key markets Aehr is addressing for semiconductor wafer level testing and burn in have significant growth opportunities that will expand this year and throughout this decade, and we're seeing increased customer engagement in each of these markets. We've also seen a recent strengthening in the silicon carbide market for electric vehicles outside the U.

Speaker 2

S. And what appears to be a shift in market share of electric vehicle suppliers. This clearly includes Asia, where we recently had an extensive and very productive visit with a significant number of silicon carbide suppliers and electric vehicle suppliers. On today's call, I'll discuss each of the major market segments Aerie is addressing for wafer level burn in semiconductors, which includes silicon carbide, gallium nitride, silicon photonics and memory semiconductors as well as tee up an opportunity we hope to discuss in the coming months. I'll also include the trends we're seeing in Asia EV suppliers and impact on silicon carbide and Air's opportunity to address this market.

Speaker 2

According to market forecasts, including the Semiconductor Industry Association, the semiconductor industry expected to grow from $600,000,000,000 in 2022 and by the way, we apologize, someone noted that that was incorrectly noted as $1,000,000 in our press release, so we'll get that corrected to over $1,000,000,000,000 at or around 2,030. This acceleration is coming from mega market drivers, including artificial intelligence, green energy and decarbonization and IoT based digital transformation. Increased reliability concerns about semiconductors in a growing number of mission critical applications as well as more multi chip modules or heterogeneous integration with multiple devices being assembled together in a single package are driving the need for wafer level burn in. At semiconductor conferences around the world, we're seeing an increased focus on moving test and burn in to wafer level before these devices are put into multi chip packages or modules. These favorable macro trends are driving the business that drives Aehr Test and include the following: silicon carbide power devices going into high density modules for power conversion in electric vehicles gallium nitride power semiconductors going into automotive, salt, solar and other industrial applications where reliability and safety are critically important silicon photonics, where photonics integrated circuits are being put into transceivers for data center infrastructure and optical chip to chip communication of CPU, GPU and AI Processors to address the insatiable data storage and bandwidth needs of these applications.

Speaker 2

And memory devices, whether stack die for solid state disk drives to use in enterprise and data storage or with AI processors, again, to address the ever increasing need for memory density and bandwidth of these applications. Now let me touch on each of these briefly, starting with silicon carbide market. While we remain cautious looking ahead to the next quarter or 2, we're seeing signs of improvement in the silicon carbide market. Last week, we announced an order from a new customer for our FOX NP solution for engineering qualification small out production of their silicon carbide power devices. This customer is a multibillion dollar per year global semiconductor company with locations across Europe, Asia and Americas and has a wide range of automotive products and is entering the silicon carbide market to address several applications that include automotive, industrial and electrification infrastructure.

Speaker 2

This customer sees the enormous opportunity for silicon powered by power devices and has told us they plan to transition to our FOX XBee multi wafer test and burn in systems as they ramp to high volume production. This is the 3rd straight customer in a row for silicon carbide for us that is primarily focused on applications other than EVs. These additional applications expand our market opportunity beyond the 4,500,000 6 inches equivalent silicon carbide wafers that William Blair forecast will be needed per year by 2,030 just for electric vehicles. These new applications are driving an additional 2,800,000 6 inches equivalent wafers annually by 2,030 to address industrial, solar, electric trains, energy conversion and other applications. Interestingly, this is also the 3rd customer in row that did not need to see their wafers tested on our system before they move forward to purchase from us.

Speaker 2

I've mentioned this before, but the need for testing before purchase was essentially a requirement with our early customer engagements, and it's clear that many of our potential new customers have become much more comfortable moving forward with Aehr simply on our assurances that our solution will perform as committed. This allows the customers to accelerate their time to market. Of course, we're still happy to engage with customers if they want to see their wafers tested first. We still have yet to lose a prospective customer after demonstrating our test and burning capabilities on their wafer and have never lost a head to head evaluation to a competitive product since introducing our FOX NP and XP configured with the silicon carbide and gallium nitride test resources. While we are seeing the impact of a slower adoption of battery electric vehicles than most imagined a year ago, our initial wins and ongoing qualifications at multiple device manufacturers drive our optimism from a longer term perspective.

Speaker 2

So far, we have secured a total of 7 silicon carbide customers that have ordered our FOX P family of systems and proprietary WaferPak full wafer contactors. We're engaged with well over a dozen additional silicon carbide players in evaluations of our systems and our wafer benchmarks where we build a FOX wafer contactor for them and test their devices at Aehr Test to demonstrate the feasibility and correlation of results to meet their reliability requirements. We're focused on the qualification process with as many new customers as possible as again, once we've demonstrated our FOX wafer level test and burn in solution using their own wafers, we've not lost a potential customer yet. Our benchmarks with multiple silicon carbide suppliers continue to progress this quarter. This includes on wafer benchmark that we've been working on for multiple years.

Speaker 2

We believe and understand now that some of the market share shifts in both total market and specific end customers had an impact on and delayed new customer decision timelines. We still believe that their silicon carbide module and die sales plans will drive the need for known good die and wafer level burn in and that we will win more than our fair share of these opportunities. In addition to our customer related travel to Europe and across the U. S, we most recently had extensive visits with a significant number of Asian silicon carbide suppliers and the electric vehicle suppliers themselves. The tone and demand for EVs is much stronger outside the U.

Speaker 2

S, particularly in China and South Korea. Clearly, we also heard that there's a real need for quality, low cost, high volume automated solution for wafer level burning of silicon carbide devices, particularly in the automotive segment. Based on what we saw, the electric vehicle suppliers in China have a very strong focus on silicon carbide to the point of actively marketing silicon carbide power conversion as a differentiating feature. We personally visited several EV suppliers' sales stores, which were basically all in malls or retail shopping areas like we see Tesla here in the U. S.

Speaker 2

And 3 of them basically position their silicon carbide based EVs as superior, almost apologizing that this particular version is only IGBT, but next year's model is silicon carbide based. They had no idea who we were or that we have any skin in the game for silicon carbide. Another notable was that we heard across the board from both the AV suppliers themselves and also the power semi suppliers is that all the Asia electric vehicle suppliers appear to be driving to build module based silicon carbide for their power inverters in their cars rather than the discrete devices like what Tesla has done. And they also have a very high expectation for delivering quality. We even heard from multiple companies that they're driving to supply silicon carbide and wafer level burn in to local suppliers because they believe they can get higher quality known good die than they can from suppliers outside of Asia.

Speaker 2

Driving wafer level burn in devices before they're put into modules is critically important to them to remove infant mortality, which bodes well for our solutions. Per a report last year, UBS forecasted that in 2023, 91% of the batteries sold in electric vehicles would be 400 volt and only 9% would be 800 volt. But by 2026, UBS expects the percentage of 800 volt batteries to be above 30%. The report also focused on the progression of electric vehicle batteries from 400 to 800 volt, which is generally recognized by the industry where the silicon carbide is mandatory to get the range and recharging speed consumers are demanding. This is why it appears so many silicon carbide suppliers are timing their major ramps to be in 20252026 timeframe.

Speaker 2

So in the next couple of years, we expect Aehr to benefit from both an increased number of electric vehicles being sold as well as a a significant increase in silicon carbide being our solution for those electric vehicles. The electric vehicle market in Asia, particularly China and South Korea is very robust, supported by public and consumer sentiment. And they have some really incredible cars that are being built for electric vehicles. And I now fully understand why Tesla stated that their key competition is from Asia and why both U. S.

Speaker 2

And European auto suppliers in particular are so worried. From the feedback we received from a significant number of potential customers in Asia, we believe that Aehr's proprietary wafer level burden systems based upon our patented proprietary wafer pack contactors appear to have a key value proposition and we see high degree of interest in our solutions. We already have people and infrastructure across Asia, including China. We have shipped and supported our packaged part burn in systems into China for many years and have also already shipped our FOX wafer level test and burn in systems into China a few years ago. Based on customer commitments, we're discussing expanding our presence in China in terms of support infrastructure and resources.

Speaker 2

We have also put additional measures in place to ensure the protection of our IP and patents that we feel will help to secure our proprietary capabilities and allow us to grow and maintain market share over time. We look forward to providing updates on our plans over the next few months. Now let me discuss our progress with testing burning gallium nitride power semiconductors. We continue to be encouraged by this market and believe it will be significant in terms of market size for semiconductors. In addition to its wide adoption in consumer devices such as cell phones, tablets and laptop computers, Gallium Nitride is being targeted for use in solar, data centers and automobiles, whether electric or traditional gasoline automobiles.

Speaker 2

The critical reliability needs of these target markets appear to be increasingly driving production burn in requirements. And ARRIS FOX P multi wafer system can deliver both the power and high voltage required to do massive parallel per die and multiple wafer tests of Gallium Nitride devices for a very cost effective solution. During the quarter, we announced our first order for a FOX wafer level test and burn in system to be used for Gallium Nitride Devices, and we have a second potential Fox system customer that has been purchasing our wafer pack contactors for their on-site evaluation that we believe is progressing very well. As I've noted before, we're working with several of the GaN suppliers, including the 2 market leaders, which positions us front and center in this market that we believe is another potential significant growth driver for our wafer level solutions. The test requirements for GaN for full wafer are actually quite different than silicon carbide in terms of technical implementation.

Speaker 2

However, our FOX platform has been capable of testing these devices with the functionality and flexibility of our unique FOX Blade architecture, which allows us to configure the test blade for specific applications with the same infrastructure. This has proven to be very impressive to these customers as in fact that even they did not understand the implications of testing an entire wafer at very high voltage and the resulting impact on the test schematic due to leakages of their devices. We were able to address this with our channel modules and proprietary custom wafer packs to address the test challenge. And honestly, both Air and our customers were very happy with the flexibility of our systems to do this. We've been told now that burn in will be required for GaN going into mission critical applications such as automotive, solar and some industrial applications, and the amount of burn in time is still being worked on.

Speaker 2

Still, this is good news for us, and we feel we're well positioned to capitalize on this opportunity with our solutions in these lead customers. We're also seeing some additional new small and large players engage with us for GaN. We've been seeing consolidation within the industry of smaller key Gallon Nitride players being acquired by the larger suppliers. So all potential customers are believed to have real potential in the future. Turning to silicon photonics, which are silicon based semiconductors with integrated photon or light based transmission of signals within and into and out of the silicon via laser photonic emitters and photonic receivers.

Speaker 2

We're very excited to shift during the quarter and ahead of schedule the first order from a major silicon photonics customer for our new high power configuration of our FOX XB system for volume production wafer load burn in and stabilization of next generation silicon photonics integrated systems circuit, sorry. This new high power configuration expands the market opportunities of the FOX XP system and is configured to enable cost effective volume production test of wafers of next generation photonic integrated circuits, which are targeted for use in the new optical IO or co packaged optics market for chip to chip communication. As we discussed before, companies such as AMD, NVIDIA, Intel, TSMC and GlobalFoundries have all announced plans for silicon photonics integrated circuits and integration of these in packages with other devices such as CPUs, GPUs and AI processors. ARCBOX wafer level test and burn in solution with our proprietary wafer pack full wafer contactors are a great fit for the silicon photonics market. These next generation silicon photonics based integrated circuits can require up to 2 to 4 times as much power for full wafer test burn in and stabilization.

Speaker 2

Our new FOX production system configuration, which can be used to test and burn in these new optical IO devices, expands the market opportunity of the FOX XP system even further. In addition, the power and functionality of lasers used to transmit data are critically important to the performance of the communication channel. And air solutions not only weed out early life failures, but also improve the performance of the device through what the photonics industry refers to as stabilization. During the 1st day or 2 of normal operation, the laser output characteristics change in an exponentially decaying manner and must be stabilized until the decaying stops before the final product can be tuned to meet its performance specifications. Air can do this across an entire wafer fully integrated photonic integrated circuits with embedded or attached laser emitters.

Speaker 2

Aehr currently has 6 customers using our systems for production tests of their silicon photonics devices, 5 using our NP and XP systems for wafer level test and burn in and one using both systems for engineering production burn in of individual simulated die and modules using our proprietary DiePaks. While the timing of these devices and volume ramps are not publicly clear, we remain very enthusiastic about the silicon photonics market and are watching this market very closely. We continue to work with some of the leaders in silicon photonics to ensure that we have the products and solutions available to meet their needs for this potentially significant market application. Now on to memory. According to the average of multiple market forecasters in 'twenty four, memory semiconductors will make up over 50% of the total semiconductor wafer shipped in the whole world.

Speaker 2

This is approximately half NAND flash memory and half DRAM. We are making continued progress in our ongoing discussions with multiple memory suppliers. We see the memory market as a significant opportunity for us to deliver wafer level burning solutions to help memory suppliers meet their reliability and quality needs, particularly with stacked die applications. During the next year, we're driving for our 1st on wafer benchmark in partnership with a leading NAND supplier using our proprietary WaferPaks and FOX wafer level test and burn in system with our new fully automated waferPak aligner. We see an initial opportunity for test in NAND for solid state disk drives used in enterprise and data storage where Air can deliver compelling cost effectiveness and also weed out infant mortality issues before multiple die are put in a single package.

Speaker 2

Longer term, we believe DRAM will be a critical target market for our systems, particularly as a percentage of DRAM going into multi chip modules such as GPUs, CPUs and AI processors increases. Now I want to spend a minute on the overall artificial intelligence semiconductor market. I've already discussed how we're working with silicon photonics suppliers for their plans at integrating silicon photonics as optical communication transceivers and devices, including AI processors. We also see co package memory in AI processors as a key driver for wafer level burning of DRAM for these devices. We also see a significant opportunity for the AI processors themselves.

Speaker 2

Our new high power FOX system that we discussed for optical IO semiconductor burn in, the FOX XP multi wafer production system we began shipping last month is the world's highest power per wafer system on the market and it handles up to 9 wafers at a time, also unprecedented in the industry. This system is capable of testing up to full 300 millimeter wafers of processors, up to several 1000 watts of power and over 2,000 amps of current on each of 9 wafers in parallel. By moving the burn in from package module to our final system format is done today to and move it to wafer level, our customers can achieve enormous savings related to yield loss of modules with up to hundreds of other devices or chiplets in the same module. On the case to system level test, the cost of the WIP inventory and yield loss of infrastructure of the system surrounding these modules or chips. The wafer level burn in challenges we're working on include putting extremely high currents onto the wafer without damaging the wafer or the contactor, thermal management of the high power devices with very high leakage currents associated with the high burn in temperatures we can apply, and automation and handling of these very expensive wafers built on the most state of the art logic process geometries in the world.

Speaker 2

Stay tuned to hear more about this exciting new application for our products over the next several months. And lastly, I want to discuss our wafer packs, which are basically the consumable that accompanies and is required with all of our FOX wafer level test and burning systems. We continue to be very pleased with the continued stream of new designs for wafer packs. Our new design volume has almost doubled this year compared to last year as we're seeing more and more design spending, silicon carbide, GaN, silicon photonics and other applications. As a result, our customers are buying additional wafer pack contactors for these new designs, highlighting the recurring revenue part of our business.

Speaker 2

As we've noted before, our proprietary WaferPak contactors are needed with our FOX wafer level test and burn in systems to make contact with the individual die on the wafer and are designed specifically for a given device. As our customers win new designs from their customers, Aehr eventually secures orders for new wafer packs to fulfill these new wins. With each new design, our customers will need enough new WaferPaks to meet the volume production capacity need for those new devices. Our WaferPaks will be greater than 50 percent of our total revenues this fiscal year, which is fantastic and underscores the business model that allows us to grow both from added capacity from our FOX systems, but also with wafer packs to serve an ever increasing installed base. To conclude, as we head towards the start of fiscal 'twenty five on June 1, we're very encouraged and optimistic about our increase in engagements and the long term growth opportunities of all these markets and are excited to continue on our path of becoming the world standard for wafer level test and burn in for the semiconductor industry.

Speaker 2

And with that, let me turn it over to Chris before we open up the line for questions.

Speaker 3

Thank you, Gaye, and good afternoon, everyone. The company recognized solid bookings in the Q3 of fiscal 2024. Bookings totaled $24,500,000 compared to just $2,200,000 in the Q2 of fiscal 2024. Our backlog as of quarter end was 20,000,000 dollars We expect to recognize revenue from the majority of these orders for systems, wafer packs, aligners and services in the last quarter of fiscal 2024, which ends on May 31, 2024. Looking at our financial results for the Q3, total revenue was $7,600,000 down 56% from $17,200,000 in Q3 last year.

Speaker 3

As we noted in our earnings preannouncement last month, the decrease in revenue was due to the timing of some significant customer orders. In just the last 2 weeks of Q3, we saw delays in a couple of customer orders that had planned shipments in the quarter as well as a last minute push out by a customer of a system in our backlog from the fiscal Q3 to the current fiscal Q4. WaferPak revenues were 4,800,000 dollars and accounted for 63% of our total revenue in the 3rd quarter, which is higher than 37% of total revenue in the prior year of Q3. Customers typically buy wafer packs from us subsequent to purchasing their new FOX systems. Additionally, customers also buy WaferPak from us as they change their chip design for smaller and more efficient devices for their OEM customers.

Speaker 3

We're seeing continued momentum for new wafer pack designs from both our existing and new customers as they look to meet their end customer and market requirements. GAAP gross margin for the 3rd quarter came in at 41.7%, down from 51.6% in Q3 last year. The decrease in gross margin is primarily due to lower revenue resulting in a higher overhead absorption rate and lower manufacturing efficiencies. Operating expenses in the 3rd quarter were $5,200,000 up slightly from $5,100,000 in Q3 last year. The year over year increase is primarily due to higher R and D expenses, which were partially offset by lower SG and A expenses.

Speaker 3

The increase in R and D in Q3 from the same period last year was primarily due to costs associated with our continuing efforts to augment the features and performance of our automated wafer pack aligner and higher personnel expenses. We have hired R and D talent in both hardware and software and have invested in R and D programs to enhance our existing market leading products and meeting our competitive advantages. At the end of Q3, we announced we shipped the first order from a major CECOM Photonics customer for high power configuration of our FOX XP system for volume production wafer level burning and stabilization of next generation SICOM Photonics Integrated Circuits. Non GAAP net loss, which excludes the impact of stock based compensation, was $900,000 or $0.03 per diluted share for the 3rd quarter. This is down from non GAAP net income of 4,700,000 dollars or $0.16 per diluted share in the Q3 of fiscal 2023.

Speaker 3

We expect to return to profitability in our Q4 of fiscal 2024. Moving to the balance sheet. We continue to maintain a healthy balance sheet. Our cash and cash equivalents were $47,600,000 at the end of Q3, down from $50,500,000 at the end of Q2. With a solid balance sheet, we continue to invest in scaling our business and entering into new markets and supporting new opportunities.

Speaker 3

We used $2,800,000 in operating cash flows during the quarter to procure inventory components primarily to support our We have 0 debt and continue investing our excess cash in money market funds. Interest income earned during this higher interest rate environment was $584,000 in the 3rd quarter compared to $374,000 in the Q3 last year. As of the end of the 3rd fiscal quarter of 2024, The remaining amount available under the previously announced $25,000,000 ATM offering was $17,700,000 We did not sell any shares during the last 3 fiscal quarters. It remains our plan to only sell shares against this ATM offering at times and prices that are most advantageous to our shareholders and to the company. Now turning to our outlook for the current fiscal year that ends on May 31, 2024.

Speaker 3

As we noted in our earnings preannouncement, our Q3 results reflect delays in wafer level burn in system orders for Sacron Carbide Semiconductor Devices used in Electric Vehicles. Due to this, we had revised our guidance for our fiscal full year ending May 31, 2024 to be greater than $65,000,000 in total revenue and net income of at least $11,000,000 which we are reaffirming today. As I mentioned before, we ended the 3rd quarter with $20,000,000 backlog and we expect to recognize the majority of that backlog as revenue in the Q4. Lastly, looking at the Investor Relations calendar, Airtest will participate in 3 investor conferences over the next few months. We will be meeting with investors at the Craig Hallum Institutional Investor Conference taking place in Minneapolis on May 29, and we will be presenting and meeting with investors at the William Blair 44th Annual Growth Conference taking place in Chicago on June 5.

Speaker 3

We will also be meeting with investors at the CEO Summit in San Francisco on July 10. We hope to see some of you at these conferences. This concludes our prepared remarks. We're now ready to take your questions. Operator, please go ahead.

Operator

Thank you. At this time, we will be conducting a question and answer Our first question comes from Christian Schwab with Craig Hallum. Please proceed.

Speaker 2

Hey, guys. Thank you for all

Speaker 4

the details gained on other target market opportunities. I just had a few questions regarding the silicon carbide electric vehicle opportunity. As you're looking into calendar 'twenty five or I guess next fiscal year '25, I guess it wasn't necessarily clear to me. Do you guys have any idea of are you expecting to see material revenue again next year from your historically largest customer? And how do you see the different customers?

Speaker 4

I know you kind of put in the press release different time frame. So I just wondered if you had if you could just make that a little bit more clear.

Speaker 2

Sure. I mean, at this point, normally we're not really talking about next year. We'll do that next call. But let me just still give you some insights because we do we certainly have visibility. A lot of it was candidly some of the same numbers just pushed out in time.

Speaker 2

So at the same time, as I say, well, they're familiar to me. We need to at least put the caveat, yes, but they pushed them out before. So I'm not foreboding anything. I'm just way more gun shy now of believing everything the customers tell me, if you will. But right now, yes, we do believe that next year we'll be getting material revenues from our actually, I believe all of our customers are expected to be taking revenue next year, including our largest historical one.

Speaker 2

We believe we'll be adding some of the key customers, candidly, some that we thought we were going to be closing by now that we still have optimism and based on our current assessment of their needs, our competitiveness, the lack of a competitor for that specific application, we think we can win them. And obviously, as you win them, you can have more visibility as to really what's going on. I think the other piece of this is that, candidly, our trip across several countries in Asia and probably the most notable would be in China was really, I guess encouraging. If you spent your whole life living in the United States listening to the news on electric vehicles, I mean, candidly, it's not I think we're all reading it. It's very different.

Speaker 2

And I saw a segment the other day, a CNBC reporter was falling around Yell and she was making comments about what she felt and saw with the EVs. And you look around Shanghai and it's like, is there really more than 50% of these cars are AUVs? And we were taking pictures of it and it's just a very different tone there and it's just a much more positive thing everywhere. And in the U. S, it has sort of this wet blanket over it that I think is placed in more political, but I don't want to get into that, okay?

Speaker 2

But nevertheless, as you look around, it's pretty encouraging. And again, we talked about these other markets too, but you're talking arc EVs. I do believe there's a lot of fabs that are being built. There's people that we believe have the inside scoop. It's kind of odd.

Speaker 2

We have some insight through the OEMs themselves as to who their favorite vendors are. Obviously, we can't share what that is, but that gives us a little bit more confidence in who we should be partnering with as well. So I know that right now, candidly, nobody wants to hear about silicon carbide in EVs, but it's still going to be a good business for us going forward, but certainly not going to be the only one for us. Okay. And by the way, when I say 25, I actually mean fiscal.

Speaker 2

So ratcheting on me in June, but I think that they a lot of that when we talk about the 'twenty five, 'twenty six model years, those are I don't even know exactly EVs aren't the same as they used to, but there's clearly people ramping up for high volume production of a bunch of new cars by next summer.

Speaker 4

Great. And then on a follow-up on China, would you anticipate seeing measurable revenue from that marketplace in the next fiscal year then?

Speaker 2

I think there's a very real chance of that and that would be our hope if not expectation. Lawyers always tell me to be careful about expectations at this point. But yes, I mean, we went there and personally sat down with almost a dozen companies and kind of got a firsthand feel and view and they're very aware of silicon carbide of what the quality is, what the issues with there are with respect to the manufacturing material defects, why you need burn and how long you need to do it for, what are the burn in requirements. I candidly found them to be quite knowledgeable. And this may come across a little boisterous, but candidly, I think the smarter people are with silicon carbide, the better we look because they really understand what it is we're doing.

Speaker 2

And that's what I felt when I was in Korea, Japan and China. So to some extent, they have learned this enough and then they are now being much more clear about why they need wafer level burn in and what they're looking for. And that bodes well because I believe I truly believe we have the best solution on the market.

Speaker 4

And then my last question again is just a follow-up on the China market. Is that something that you would address with the direct sales force or would you partner with somebody local for distribution?

Speaker 2

Yes, a little both and we've already done that. I mean, I think we have a dozen customers in China. Most people don't remember that. But if you go back and look, we have a bunch of ABTS systems that were sold all over China with us as a FOX system. So we have local air employees there, both sales, applications and infrastructure.

Speaker 2

But in China, it's pretty typical that you also use reps that have close relationships with sort of different geographies and we have that as well. So they would get a specific commission on a sale. And that's I think almost everything we've sold in China has had some of that, not all of it, but most of it. So it's a little of both. But we're also looking at upping our presence pretty significantly, including dropping in a demo set center, some local infrastructure and some other things to give us more girth, specifically at the request of about a half a dozen companies.

Speaker 4

Okay, great. No other questions. Thank you.

Speaker 2

Okay. The

Operator

next question comes from Jed Dorsheimer with William Blair. Please proceed.

Speaker 5

Hi, thanks. Hey guys, just a few questions. I guess, first one, the FOX MP new customer, you described as a semiconductor global semiconductor manufacturer. Is that also a Tier 1 automotive customer? I'm just wondering if some categorize it as both.

Speaker 2

So I'm going to try throughout today and in each call try and get more and more vague only because we've been getting feedback from customers to be particularly vague. Now this particular customer wasn't one of those, but I'll answer that question. It's not a Tier one. Okay. Their entire business is semiconductors.

Speaker 5

And what would you expect the timing to be in terms of conversion from an MP to an XP with that customer?

Speaker 2

Actually, I want to hold back on that a little bit with respect to what their timing is because my understanding is that's part of their secret sauce, etcetera. But if I told you over the next couple of years, it's pretty generic, I realize. But they we know that they have made some substantial purchases for front end equipment and other things as well. And the NP is just their engineering bring up tool. And that has no intention of being able to address their production.

Speaker 2

So whether it be next year or the following year, you can leave it at that for now. Maybe I'll give you more visibility next time, okay?

Speaker 5

Okay. And then it's helpful on your excitement over the China market. I'm just curious, are you going to outline how you intend to address the dilemma which has kind of caught most tool companies off guard where local subsidies require reengineering of tooling to a local supply chain.

Speaker 2

Yes. I mean, I think what I want to say is we're not ignoring that and we're not believing that we have all the answers. We have some specific legal IP security and contractual things that we're going to use. I'd love to tell you something besides to slow it down, but we've also have there's that we have reason to believe that it's not that easy to directly knock off our system without not off our system without actually violating our IP or to get close enough to do it. We also have a lot of software and a lot of other things.

Speaker 2

I don't think it's that easy to just simply do it. And then if you did, you would have some other issues. So we're conscious of it. I don't want to be and we're specifically doing things that we're not going to publicly announce all the things that we're doing as part of the reason to keep it secure.

Speaker 5

Got it. Okay. And then non silicon carbide gain. For silicon carbide, the inherent defect density of the material combined with a shift to modules kind of created this perfect opportunity for wafer level burn in. As you look at the silicon market where you have a homogeneous material structure and chipset, Is it to open up memory and to some extent silicon photonics, is this or largely memory in silicon, is this really just a function of moving to modules or chiplets that kind of triggers that?

Speaker 5

Could you help articulate what you think will be the gating factor there?

Speaker 2

Okay. So if you want to step back and just say, okay, what are the really big things driving our market? Okay. First of all, all right, the market is growing from $600,000,000,000 to $1,000,000,000,000 Semiconductors, many of them are not actually getting more reliable. Things like very low geometry processes, the processors that we're talking about, AI processors, CPUs, they're all burnt in today, okay?

Speaker 2

That's nothing new. They're just burnt in, in a package form in normal. But then people are actually putting them into and by the way, in some cases, they weren't burning them in. Then they're putting them into applications where they were, okay? There are processor companies that ship devices to a consumer application that don't burn them in, but always burn them in to automotive.

Speaker 2

Well, there's more and more automotive and other things that matter to the reliability. And then the last thing, which really drives wafer level would be you're putting in the multi chip modules, right? So specifically on memory, you're like, wait a minute, which ones does it matter? Memory has long required a burden process. Every DRAM is burnt in and all the NAND devices that are going to end up going into a solid state disk drive have a cycling and burn in measured in fractions of days, many hours, okay.

Speaker 2

So that burn in, if you're looking for opportunities, you look for devices that then themselves need burn in, okay. Silicon photonics, every single device is burnt in. It doesn't matter where it needs to be burnt in. Then you're looking for maybe discontinuities where large volumes are going to a new application where it matters. And if you look back, it's been 20 years now, but everything that drove my test business in the early 2000s was consumer.

Speaker 2

Consumer, consumer, consumer. I remember that was all everything that mattered was always consumer. And now consumer is not what's driving the test requirements. Consumers sort of left for dead. All of the applications in data, AI, processing, automotive, etcetera are driving all the test requirements and that definitely is the case for burn in.

Speaker 2

So for memories, it's the data centers, okay. Memories are stacking together and then they're putting them together. I definitely remember and can talk to in great detail about how many die are being stacked into an SSD. And where do you want to burn them in? You should burn them in before you put them into that application.

Speaker 2

And then now what we're seeing with the likes of the A100, B200 type things, these modules, co ops packaging that actually puts a processor, a big old stack of DRAM, a chipset on their future will be an Why? Because it's the only place to do it. Well, that's ridiculously expensive. So there are initiatives to say how do we burn those devices in at the die level. And I can tell you sort of just front and center my whole career at this thing.

Speaker 2

When you start with, I need to do it, there are testability, DFT and other things that you can do to implement it. And we believe we have a solution that can partner with them to actually implement wafer level burn in. So the applications that will be driving our business today are very different than I think they will be in a couple of years. I mean, I still think silicon carbide is going to be a really good business for us, but it won't be the only one.

Speaker 5

So, gain, sorry, the move to multi chip modules from an economic perspective is the driver then in terms of It's the

Speaker 2

catalyst that makes them relook at their test strategy and say, I'm going to need to do more wafer level, Correct.

Speaker 5

Got it. And the reason they're not doing that with your system today is they're selling for price where they can eat the yield loss or Yes, it's

Speaker 2

a good question, but it's not crazy. Sorry, I don't have to imply you're crazy, Jed. But if you're able to get 97% margin and 50% yield loss, who cares, I guess. I mean, I'm not implying I know that answer. And if I did, I'm not telling It is but that would be logical.

Speaker 2

But as things become more important or you don't have capacity or that money matters, yes, you would drive it. And so I think that's what makes sense why we're feeling these sort of tops down initiatives for shifting things towards wafer level.

Speaker 5

Got it. That's helpful. I'll jump back in the queue. Thank you.

Speaker 3

Okay. Thanks, Jed. Thank

Operator

Next, we have Larry Slabina with Slabina Capital. Please proceed.

Speaker 1

Hi, gang.

Speaker 2

Hey, Larry.

Speaker 6

How are you doing? Hey, Corning's CEO on his last quarter earnings report, he was really optimistic on what he called the 2nd optical network that's going to be deployed, hooking up GPUs and AI data centers. And since you were pushed to ship your optical IO production system to get it out as soon as possible, Do you have a sense of when this may show up in the marketplace?

Speaker 2

Yes. And I okay. So it's one of the I feel like it's one of the most tightly guarded secrets, okay. And I don't believe that we're even being told everything correctly. That sounds probably you don't want to hear that, but I think we I know more than I can say and I still know we have everything.

Speaker 2

What I have mentioned, I think you heard me in the past and what I sort of struggled with is if you go out and you look at someone like a Yoel, who's really smart and understands this optical space very well, okay, And they look at the optical IO, they're like, well, I'm not sure how big that market is going to be, etcetera, etcetera. It's like, oh, what is what is NVIDIA or AMD tell you? Oh, they won't tell me anything. Like you go figure, right? Of course, they're not telling them.

Speaker 2

The reality in my mind is what AMD, Intel, NVIDIA, pick your other processor, what their plans are, that's what's going to drive it. And those are very closed environments. They're not I don't believe for a minute that NVIDIA and AMD are talking together about how they can get their processors to talk to each other, okay? So, you kind of have to watch on the edges. You watch where the investments are made.

Speaker 2

You watch what's going on. You see the technology. You watch patents. You watch tech. But my belief is, and I kind of shared this even about a year ago, it feels like we're a couple of years out to volume production.

Speaker 2

And the question is how big is it? And could it be much sooner than that? We're enabling that with our solutions and capabilities and there was a big pull for it. And keep in mind, we also have the same capability on our NP systems installed at customers. So you don't have to see all of the front edge of this simply with new systems, but we would see it with wafer packs.

Speaker 2

So there's a lot of design activities that are going on right now that seem pretty interesting to me, but I'm a believer. It makes sense. It is a critical bandwidth. It's going to be a pinch point. I think it's going to be a differentiator with all the AI guys.

Speaker 2

And it also may have the byproduct of then expanding the need for more optical even within the data centers.

Speaker 6

He seemed to think it was pretty imminent whether it was late this year, next year.

Speaker 2

I don't know if I hope he's right and we'll be ready for it. Okay.

Speaker 6

Over the last year, there's been tens of 1,000,000,000 of dollars worth of memory fabs announced by every memory manufacturer in the globe. Shouldn't you be engaged with them by now? If they're going to realize the benefits of your automated XP to reduce the size of their clean rooms and equipment costs? I mean, shouldn't you have any impact on that?

Speaker 2

Start with some,

Speaker 5

not with all of them. I'd love

Speaker 2

to be with all of them. I do think there's a little bit of a spread between the NAND and the DRAM guys timing. Just in terms of just where the DFT needs to be for DRAM to be able to actually do wafer level burn in. But I think within again, I'm in odd position as a CEO to be saying this, but personally, I would believe that people will have implemented TFT and low ping count test modes in DRAM similar to what we did in NAND 15 years ago before the end of the decade.

Speaker 5

And when

Speaker 2

that does, you want to be there and ready for it. So we've been doing things in the background to do that, be ready for it.

Speaker 6

It seems like you should have some eval tools at these guys, so they can lay out their fabs and realize the benefits of what you can bring to them. Like I said, with significantly smaller clean rooms and less equipment costs. So you can get tool record designation as soon as possible.

Speaker 2

Agreed.

Speaker 6

Hey, of the 7 current silicon carbide customers that you said you have, is that that's a correct statement, right? You have 7?

Speaker 2

Yes, 7. We officially call yes, that's correct.

Speaker 6

Okay. How many of those have bought the XP, the production system?

Speaker 2

Wow. Maybe half of them. I have to think real fast on that.

Speaker 6

Well, half of 3.5. Is that 3 or 4?

Speaker 2

Let me I'll tell you what, let me do the background real quick. We've announced them 1 at a time just do I think it's 3 XPs and 4NP type customers.

Speaker 3

Okay. I hope

Speaker 2

I got that wrong. It might be 4 till I have to go one more. Go ahead. That's all I have. And all of the plan to do XPs.

Speaker 2

I don't know if they'll ever buy another NP, they'll only do XPs next.

Speaker 6

Right. That makes sense. So the long lead item customer that's been running around the block for a couple of years, what do you think is the hold up? Is it because they don't have a large demand for modules yet, full modules, just their big customer or the big business is in what their package I

Speaker 2

think I have a pretty I think we have a pretty good idea and I cannot be able to answer it directly. So I think if you look at the if you look at sort of what happened just in the shift of the EV from every one of their brothers going to be driving an EV in 4 years to now the oh my gosh, is it going to deploy as fast or whatever. That shift over the last 6 months, I think, has really caught a lot of people off guard and made them sort of just look back and assess it and make sure this thing isn't going to go off a cliff. In reality, I think there's some things where the people that were strong will ultimately be stronger. My guess is some of the smaller players that thought this will be fun to dabble in aren't going to, right?

Speaker 2

I mean, like you don't want to it will be more fortified. That gives the larger players, which this customer would be one of them, more confidence in their plans going forward. I think there's been things in the OEM space with respect to what kind of commitments need to be made in order to secure fab capacity that is being played out right now. And I think there have been some market shifts in the industry that can shift around seemingly with no particular impact, but may have impacted us. I know they have.

Speaker 2

And so do you think Go ahead. Do you

Speaker 6

think it might have anything to do with waiting for 200 millimeter then going full throttle with your fully automated systems?

Speaker 2

I mean, these are the customers we talk to want to ensure that we can do both 6 inches and 8 inches or 200 millimeter. So in that sense, maybe, but nobody is saying, oh, your system only needs to do 200 millimeter. So I'm not

Speaker 6

So they won't have to buy multiple wafer packs?

Speaker 2

Yes. We've got some tricks around that as well. But there may be some of that, Larry, and it may be that, okay, why don't we start the line on the 200 millimeter line instead of there's always process things. I think I can think of some customers where that's the case. But like I said, it's actually interesting.

Speaker 2

We're I'm engaged with customer right now. I want fully automation, 200 milligrams, 200 milligrams, okay, we'll deliver $200,000,000 Yes, the first wafer is going to be 6 inches You're like, okay. Well, it's an end effector on our automation. It's no big deal. But so I don't know exactly, sorry.

Speaker 6

Well, I'm thinking, so they don't have to buy a bunch of 6 inches wafer packs, so just go with 8 inch and move forward. Anyway, getting back to memory, did you say did you give a timeline on when you thought you were going to penetrate 1 of them in terms of evalu or?

Speaker 2

In our prepared remarks, I said something to the effect of this year, we are hoping to have a on wafer benchmark process going. That's what we said.

Speaker 6

I mean, I'm assuming they would want to have an evaluation tool at their disposal. You would have to supply a tech person. But isn't that the way that kind of a business would have to go?

Speaker 2

Yes. That's why most of it works. I don't want to share all of the way we would have structured the conversations with the more than one memory customer just for maybe obvious reasons, because people have slightly different variations of what their expectations are. But candidly and publicly, we're in. I think it's a matter of partnering with those customers, taking it working with them on their key testability and DFT modes and how they go about their cycling burn in test, DFT best, low ping count test modes, all things that I spent my whole career at prior to this.

Speaker 2

Those key differentiations as a vendor you want to say yes to how can I help? The critical aspects are the low cost contactor, the full automation and alignment, high performance, high parallelism, very small footprint on wafer starts per month. So those are critical aspects that we have key differentiation on. And then working with those customers on their specific and unique test requirements for their particular devices, it would be part of the process.

Speaker 6

Yes. That's why, you got to get in there before those fabs are fab designs are locked down. So that, you know, they can design the fab around your equipment with the smaller clean rooms and whatever, right?

Speaker 2

Yes. I mean, yes and no. I mean, again, I don't want to give a so traditionally, burn in is considered a back end of test. All of test is considered back end in semiconductors, but burn in is often done. So you can you could shift your wafers to your back end facility before singulation as well.

Speaker 2

So again, if I see a fab is built and they haven't put my tool in there, I don't I'm not saying, oh gosh, I've missed it. That's just not true.

Speaker 6

Okay. I was thinking that the sorting on especially flash, the sorting is still in the fab, right?

Speaker 2

Most of the time, yes. Okay.

Speaker 6

All right. That's all I had. Thank you.

Speaker 2

Thank you. Thank you. Okay. We

Operator

show no one further in queue. I'd like to turn it back to management for any closing remarks.

Speaker 2

All right. Well, then we covered enough of the topics in the questions. Hopefully, it answered all the people that had sent in. As always, we appreciate your time on here, and we look forward to either seeing you at one of the investor conferences or on our next call. That will be Q4 and fiscal year 'twenty four end, so it'll be somewhere mid July or so.

Speaker 2

At that point, we'll also be giving guidance for our fiscal 'twenty five. As always, if you happen to be anywhere near the Bay Area and Silicon Valley, look us up. We'd be happy to do a meet and greet and give you a tour of our manufacturing floor. It's quite impressive. Thank you everybody and have a nice day.

Speaker 2

Thank you.

Operator

This concludes today's conference and you may disconnect your lines at this time. Thank you for your participation.
