Gary?

Thank you, Leslie, and good afternoon to everyone. Revenue for the fourth quarter of 2024 was $25.1 million compared with $23.6 million in the third quarter of 2024, and $20.4 million in the fourth quarter of 2023. To break down our Q424 revenue for you by product category, indium phosphide was $9.1 million, reflecting continued demand from data center applications, including AI, as well as passive optical networks. Gallium arsenide was $5.4 million, germanium substrates were $1.6 million, And finally, revenue from our consolidated raw material joint venture companies in Q4 was $9.0 million based on continued healthy demand. In the fourth quarter of 2024, revenue from Asia Pacific was 79%, Europe was 11%, and North America was 10%. The top five customers generated approximately 36% of total revenue, and one customer was over the 10% level. Non-GAAP gross margin in the fourth quarter was 17.9%, compared with 24.3% in Q3 of 2024, and 23.2% in Q4 of 2023. For those who prefer to track results on a GAAP basis, gross margin in the fourth quarter was 17.6%, compared with 24.0% in Q3, and 22.6% in Q4 of 2023. The decline in gross margin is primarily the result of lower benefits from our recycling program in the quarter, as well as lower ingot starts and crystal growth, which resulted in under-absorption of our manufacturing overhead, but which also enabled us to reduce the inventory. Moving to operating expenses, total non-GAAP operating expense in Q4 was $9.9 million, compared with $9.0 million in Q3 of 2024 and $7.5 million in Q4 of 2023. On a GAAP basis, total operating expense in Q4 was $10.6 million compared with $9.1 million in Q3 and $8.2 million in Q4 of 2023. The increase in OPEX in Q4 was primarily the result of an increase in legal expenses as well as an increase in R&D expenses related to investment in low EPD gallium arsenide crystal growth for the wireless market. We also continue to invest in the development of our 6-inch indium phosphide for a variety of applications. Our non-GAAP operating loss for the fourth quarter of 2024 was $5.4 million compared with a non-GAAP operating loss in Q3 of 2024 of $2.6 million and a non-GAAP operating loss of $2.7 million in Q4 of 2023. For reference, our GAAP operating line for the fourth quarter of 2024 was a loss of $6.2 million compared with an operating loss of $3.4 million in Q3 and an operating loss of $3.6 million in Q4 of 2023. Non-operating other income and expense and other items below the operating line for the fourth quarter of 2024 was a net gain of $1.1 million. The details can be seen in the P&L included in our press release today. For Q4 2024, we had a non-GAAP net loss of $4.3 million or $0.10 per share compared with a non-GAAP net loss of $2.1 million or $0.05 per share in the third quarter of 2024. Non-GAAP net loss in Q4 2023 was $2.8 million or $0.07 per share. On a GAAP basis, net loss in Q4 was $5.1 million or $0.12 per share. By comparison, net loss was $2.9 million, or $0.07 per share, in the third quarter of 2024. And the gap net loss in Q4 of 2023 was $3.6 million, or $0.09 per share. The weighted average basic shares outstanding in Q4 was $43.4 million. Cash, cash equivalents, and investments decreased by $5.0 million to $33.8 million as of December 31st. By comparison, at September 30th, it was $38.8 million. The decrease is mostly balance sheet related as over $3 million of the total loss was made up from non-cash depreciation and stock comp. The biggest balance sheet item was that we reduced our loan balance by $6.8 million. Depreciation and amortization in the fourth quarter was $2.2 million. Total stock comp was $0.8 million. Net inventory was down a bit over $1 million in the fourth quarter to $85.1 million, down from the peak by $6.6 million, and we are working to bring it down further. Finished goods make up less than $3 million, and that is a positive. This concludes our discussion of the quarterly financials. For the fiscal year 2024, in total, revenue was $99.4 million, up from $75.8 million in fiscal year 2023, and reflecting growth in every revenue category across our portfolio. This is a 31% increase in revenue and underscores the improvements we're seeing in our business, with major market trends driving the adoption of new technologies, a recovery in the global demand environment, and our own success in winning share at strategic customers. Gross margin for the fiscal year 2024 on a non-GAAP basis was 24.3%, up from 18.1% for fiscal 2023. Gap gross margin for 2024 was 24% of revenue, up from 17.6 for fiscal year 2023. Net loss for the fiscal year 2024 on a non-gap basis improved to $8.5 million, or $0.20 per diluted share, compared to the net loss of $14.3 million, or $0.34 per share, for fiscal year 2023. Gap net loss for the physical year 2024 was $11.6 million, or $0.27 per diluted share, up from a net loss of $17.9 million, or $0.42 per share, for fiscal year 2023. Turning to our plan to list our subsidiary, Tong Mei, in China on the star market in Shanghai, we have continued to keep our IPO application current. Tong Mei remains in process as part of a much more selective and smaller group of prospective listings than a few years ago. We continue to think that Tong Mei is a good IPO candidate, and we will keep you informed of any updates. With that, I'll now turn the call over to Dr. Morris Young for a review of our business and markets. Morris?

Thank you, Gary. While Q4 gross margin and net loss fell short of our expectation, our improvement in 2024 over the previous year was significant. We delivered a 31% increase in fiscal year revenue, a 6% improvement in non-GAAP gross margin, and 40% improvement in non-GAAP net loss over the last 12 months we have aggressively advanced the technical specifications of our material to help our global customer base solve complex next-generation connectivity challenges more and more the materials we supply are being used in highly sophisticated applications such as high-speed E-Connects, where our breakthroughs in delivering extremely low EPDs are showing tremendous value to device performance. 2024 marked a very meaningful year of revenue growth into the cloud and data center infrastructure market, as well as our successful penetration of wireless handset market, particularly in China. We have also expanded our portfolio of our raw material companies, creating a unique, valuable supply chain and laying the groundwork for incremental revenue opportunities in new markets such as PBN. And finally, we brought to market both 8-inch gallium arsenide and 6-inch Indian phosphide substrates driving new innovation into our development capabilities that we can translate into better performance and higher yield across our product families as we look ahead of 2025 well there are some new challenges we see a number of exciting opportunities created by both industry trend and company specific opportunities now first two challenges as many of you may know on February 4th China government imposed trace restrictions on the export of Indian phosphide material similar to the 2023 restriction on gallium arsenide substrates these regulations explicitly seek to restrict the export of material used for military applications therefore we're now undertaking an export permit process for Indian phosphide similar to what we have been working through with gallium arsenide over the last two years the good news is that it is an organized and efficient process that we're very familiar with and we believe that we have similar success we will have similar success we're already working with our customers outside of china to prepare applications on their behalf and expect to be able to submit our first application in early march in our experience we typically hear back initial applications within 40 to 45 business days and repeat applications are often processed faster. As such, we expect to see a delay in a portion of our Indian phosphorus revenue in Q1 as we begin this process. For reference, in 2024, about 40% of our Indian phosphorus revenue came from China, and with about 60 percent coming from the rest of the world. In Q1, we expect the impact of our revenue line of approximately four to five million dollars in delayed sales. This said, we don't believe that any of our Indian phosphide sales go to military applications, so we feel we're in a good position to realize sales once we can navigate the permit process. Now, challenges aside, let's turn to AXE key business opportunities and growth drivers for 2025. In cloud and data center connectivity, customers are pushing the boundary of high-speed optical interconnects to support the growth of AI adoptions. Recent algorithmic improvements have shown the potential to deliver AI applications with better returns on investment for AI infrastructure providers worldwide. These innovations can enable increased adoption and broader use case for AI globally. within this use case we have several new and emerging opportunities first the industry is beginning its transition from vixel lasers to speed of 50 gig per lane to 100 gig per lane and higher not only are these high-speed vixos opening up new opportunity for us with gallium arsenide, they have also created a greenfield market opportunity for high-speed Indian phosphide-based photodetectors in 400 and 800-gig multimode optical interconnects. We saw Indian phosphide orders relating to this application throughout 2024, which we believe will continue to grow in 2025. Our R&D investments have allowed us to deliver significant innovation on extremely low EPD ion-doped Indian phosphide substrates for next-generation EML lasers for 800GB and 1.6T pluggable transceivers. EPD refers to the defect density of a material and is a critical specification in device reliability. I am extremely proud of our team for their breakthrough achievement. I believe AXC leads the industry in low EPD iron-dope material. We are currently in the qualification path of a major supplier for deployment in 2026. Initial feedback from our customers suggests that our low EPD characteristics is translating to highly valuable performance and reliability advantages over competing material. We continue to work with a number of customers worldwide and are also seeing exciting opportunities with next-generation silicon photonics devices for 800 gig and 1.6 T plug-able transceivers for median to long-distance transmission. For example, we saw growth in demand with increased orders in Q3 and Q4 from one of our largest U.S. silicon photonics customers. We also believe that China data centers are preparing for broader adoption of optical technology, which we view as an emerging opportunity. It is worthwhile to know that we are actively working with customers on their roadmap for co-packaged optics and view this as a major opportunity. One of the hardest challenges for this emerging technology to overcome will be the reliability at scale, which is where low EPD wafers make a critical difference. We believe that our ability to provide extremely low EPD substrates will help customers solve this challenge when the industry moves towards widespread adoption in the years to come. In addition to data center and AI applications, we see a second exciting opportunity in 2025 for our galling on-site substrates in HPT devices for the wireless market. Just two years ago, our market share was virtually zero. Today, with cost and performance breakthroughs, as well as strong relationship building with one of our largest Asian-based EPI providers, we now have about 10% of the overall market with particular strains in China. Expanding and accelerating our growth in this market is a key focus for us in 2025 with the availability of our 8-inch gallium arsenide substrates as well as the process improvement we can apply to our 6-inch line, we feel we're confident we can be extremely competitive in this market and continue to grow our market share. As a third growth driver for 2025, we see opportunities in the continued recovery of global demand environment of applications such as passive optical networks, high-power industrial lasers, particularly in China, as well as LEDs for a wide variety of use cases, including lighting, display, horticulture, and automotive. We do see the demand environment improving incrementally and inventory relatively low. And finally, we have not talked as much in recent quarters about our raw material joint ventures. I do want to note that we have continued to invest in expanding our capability and build an enviable portfolio, which today include gallium, arsenic, PBN crucibles, quartz, indian red phosphorus and germanian the strategic value of these material is not only that we can more cost effectively supply all our critical materials needed to manufacture a product but also we benefit from additional revenue streams generated by our joint ventures through the sales of this product on the open market in 2024 our consolidated joint venture generated almost 32 million dollars in revenue up 12 from the prior year we're working to expand this opportunity in 2025 through the development of new markets and to continue the valuable recycling effort that also contribute to our gross margin performance. In summary, 2024 was a year of recovery and growth for our business. One of the things that I'm most proud of is the relentless innovation spirit of our team this year in taking on highly complex material science challenges for our customers and delivering results that the industry would have considered impossible just a few short time ago these advances will enable an entirely new generation of devices capable of bringing such wonders as AI to the world what we have built and continue to build for our customers and shareholders is an incredible valuable company that can serve most cutting-edge requirements through our leading technology unique supply chain and world-class manufacturing I want to say a special thanks to our team and their family for a productive 2024 and to our customers and shareholders I want to thank you for your partnership we have worked to do on your behalf and And we are deeply committed to deliver further improvement in 2025. With that, I will turn the call back to Gary for our first quarter guidance. Gary?

Thank you, Morris. In keeping with our comments today, we expect Q1 revenue to be in the range of $18.0 million and $20.0 million. This takes into consideration growth in gallium arsenide substrates, but that's offset by the impact from the Indian phosphide trade restrictions and a modest decrease in raw material revenues. We therefore expect our non-GAAP net loss will be in the range of 13 to 15 cents, and GAAP net loss will be in the range of 15 to 17 cents. Share count will be approximately 43.5 million shares. This concludes our prepared comments. We can now answer any of your questions. Operator?

Thank you, and we will now begin the question and answer session. If you have dialed in and would like to ask a question, please press a star one on your telephone keypad to raise your hand and join the queue. If you would like to enjoy your question, please seem to press a star one again. And your first question comes from the line of Richard Shannon with Craig Callen. Please go ahead.

Well, good guys. Thanks for taking my questions. Maybe a kind of a two-part question looking back into the fourth quarter here and understanding the dynamics and how long they may continue here. So obviously a little disappointing in the gross margins and OPEX here with gross margins. I think you said some lesser benefits from recycling along with lower ingot starts here that limited absorption here. And it sounds like you are trying to trim inventory lower. So to what degree are we going to see this below kind of recent trends here? When should it come up here? And then also on the OPEX here, I think You said you were spending a little bit more R&D for Indian Phosphide for wireless. Maybe you can indicate how long investments will continue there as well.

Well, it's a fairly complex question. Gary, you want to take a first crack?

What was the first question in short? Gross margins.

A little bit lower here, a couple of dynamics here, wondering to what degree they're going to continue past the fourth quarter. uh well we do expect gross margins to be low again in q1 because um we're not going to have as much indian phosphide sales uh because of the the uh export restrictions uh following q1 then we think they'll get back into the you know at least the mid-20s which is what we were targeting and running towards and then i think that we can inch them up you know quarter by quarter.

So, yeah, I think to answer the question about the R&D activities, yes, we have taken quite a bit of effort in, well, both six-inch in the phosphide development and also leveraging our A-inch, crystal growth knowledge we learned on A-inch and applying that technology to our six-inch line which take us quite a bit of development effort but I think it's on the tail end of that effort we should start to join enjoy the benefit of better yield and better performance on the six inch line with the knowledge we

have our age okay thanks for that let's follow up on any of phosphide here it sounds like you're getting some some really good activity related to data center here maybe if you can just kind of dig in a little deeper and help us understand where you're seeing a little bit you know relatively more the opportunity whether it's coming from lasers or from uh from pds or photo detectors um i think if i caught my if my notes are right here talked about a fairly large opportunity that could come to pass uh from a revenue perspective in 26 maybe you can provide some a little bit more information on that as well morris thank you um tim you want to take that on that question because i think uh i mean although

I can answer that, but Tim is probably the front line knowing about this opportunity we should have in 2026 on the low EPD stuff for the EML, right, Tim?

Yeah, right. So what we've seen in 24 is we've seen growth both on the photodetector side and the laser side of it, right? So So on the photodetector side, we've got this greenfield opportunity, which we've talked about in the past, where the high-speed Vixels running at 100 gig per lane now need to move over to an in-gas indium phosphide-based photodetector. So obviously, the world is seeing a lot of growth in the gallium arsenide Vixel-based transceivers for us. And we're enjoying that, too, that this Greenfield opportunity has opened up for the indium phosphide side of it. We're also seeing a really healthy increase in the data center laser side of it. And as you probably know, we're focused more on the silicon photonic side and the EML side than we are on the more traditional DML-based applications. We're not participating that heavily in the DML side of it, and you'll see more growth coming through 2025 as the industry moves to the EML and the silicon. One of the interesting things as well that Morris mentioned was this new application on low EPD iron doped. We're definitely seeing, I think, some new opportunities coming up there with a number of different customers. It's something to keep an eye on for next-generation EMLs. I think we'll see some growth through there in 2025 and into 2026. So, yeah, I think we're going to see some healthy growth rate on, again, both lasers and detectors in 2025.

So let me chime in here. little bit perhaps you know EML it means you have a laser based device and you use any phosphide modulator on the chip to regulate on and off performance of this module right and I think most of the lasers requires low EPD and on the traditional method of making laser is using sulfur dope to strengthen the lattice to reduce the defect density to a slowest less than a hundred per centimeter square okay because lasers are very sensitive to defect density EPDs however if you want to use iron doped material iron though doesn't have the benefit of lattice hardening so the EPD of this iron dope material traditionally is in the thousands of EPD so while you want to combine and the reason why you want to use iron dope I think has something to do with the transient time being shorter so you can modulate this device faster so you have a faster response. However, you also need a lower EPD to make this device more reliable. So you are caught in between wanting the device to perform better with the EML and also want a lower EPD to improve the reliability. And we believe that we have the ability to make the EPD lower than our competition, and our customers are finding out these are proof out to be more desirable for the EML development.

Okay, thanks for all that detail, Morse. I'm going to ask one more question and jump out of line here, and that's related to China and the tariffs and export controls. You had some preparer to marks who were very helpful here. it sounds like you expect the experience of the permitting or licensing process to be similar to what you saw in gallium arsenide. And while you're obviously seeing a bit of a dip here, while the length of that process kind of unfolds here. But I guess just want to make sure that you're not expecting any issues. And maybe looking back to your experience in gallium arsenide, did you have any that you would expect to be better or worse than when we get to Indian phosphide.

Yeah, Tim, again, you're the honcho on developing the export. So can you answer that question, Tim, for me?

Yeah, I can. So, you know, we certainly understand the geopolitical complexities in this. And what the indium phosphide controls, and we'll call them controls rather than restrictions, what they seek to prevent is the export of materials, indium phosphide materials for military applications. When China placed controls in the export of gallium arsenide, the same thing, right? It was military applications. In indium phosphide, we don't see any of our customers, really, certainly the volume customers that use indium phosphide for military applications, it is well-known tier one customers using them predominantly for data communication, right? So we anticipate that even the true restrictions on military background, we think that we shouldn't have too many issues getting permits for non-military related customers in non-military applications. So we feel good that we can be successful in getting the permits that we need on this application.

Okay. I appreciate all the detail, guys. I will jump on the line. Thank you. Thanks, Richard.

And your next question comes from the line of Charles Xi with Needham.

Please go A question is this. Looks like you're going to see, I think if I heard you right, 45 million impact from the new licensing requirement in Q1, given that you seem to expect 45 days ish to get the licenses. Are those lost sales in Q1? You think you can make it up in Q2? But at the same time, the original scheduled shipment in Q2, could that be further pushed out into Q3? So I think that the essence of this question is, do you think you can get back to, let's say, 25 million dollar revenue per quarter in q2 or even run a little bit above that because i think you do need to get back get a shipment originally scheduled in q1 out as any color on q2 would be helpful thank you sure yeah charles i my answer to that is i think you know these if we can get the permit i think uh delivering our product is no problem okay and i think if i were the customer with a restriction on customer probably wants to

build some buffer so they could increase the the q2 delivery but you know given that could be temporary and and I I think you know I think if if if if we if we have a perfectly developed and none of our customer let's say got barred from getting a license I would say Q2 and Q3 could be a strong quarters maybe another question I think that the opportunity in wireless you talked about a couple of

years ago it was zero market share, but now you are seeing that could be a very strong potential growth opportunity this year. Mind if you talk a little bit more about what's the sizing of that opportunity and what's the shape of that ramp into that opportunity, is that do you expect it's more in the second half this year, a little bit more next year, or give up on any quantitative insights, I would really appreciate that.

Sure, Charles. I think the HPT market is very well known. I think it's roughly $80 to $100 million a year. As we said before, two years ago, we virtually had zero, and now we have about 10%. So our target is to grow out of 30% this year. And, you know, I think if we – I think the main leverage, I think the message is that we have learned quite a bit of process improvement from our age experience, leveraging that down to the six-inch line. And hopefully our knowledge there will be able to reduce our costs, improve our yield, and with a better connection and working relationship with our customers, we should be able to improve our market share. And I think, you know, the other opportunity, of course, is a longer term is you got, well, I'm hoping that with the AI implication that hopefully that AI smartphones is going to have a increased market turnover in the next year or two. If we can catch that, then we can have, you know, HPT market grow even faster.

Thanks, Maurice.

Your next question comes from the line of Tim Savicho with Northland Capital Markets. Please go ahead.

Hey, good afternoon. Just want to follow up on that answer right there quickly. Morris, was that a 10% market share target going to 30 in 25? I just want to make sure I heard you right on where the market share target is for the HPT market.

I think I was talking about, well, I mean, 10% to 30% is too much. Then we're going to have to triple. I'm talking about, you know, we have 10% market. We can increase that 10% by 30%. That will be 13% or 14%. Yes.

Glad I asked that one.

We wish it was the other way, but this is how it is.

That's all right. And you had a strong quarter in indium phosphide, I think the strongest in many quarters, and a strong year. So I guess, and this is sort of independent of the export restrictions, I think you grew 44%, 45% in indium phosphide in calendar 24. I mean, given what we're seeing in the AI optical market in particular, we're hearing about shortages of EML lasers and a lot of uptick in activity on the silicon photonics side. You know, from a market standpoint, would you have expected that growth to accelerate XME restrictions? Or how would you characterize your outlook for 25 in indium phosphide relative to what you did in 24? Again, excluding the restrictions.

Yeah, I think this is a very good question. Actually, this is a topic that Tim and I, my team, and I have constant discussion about. We buy market reports, and obviously, as a CEO, I expect the market to grow very strongly. But Tim also has responsibility to deliver revenue, so he's tempered my expectation down. So maybe I should have Tim answer that question. Tim?

Yeah, sure. So this is a very dynamic market at the moment. So it's more difficult to try and place a real number on where we go. Right now, as we put our numbers together, we're looking at growth from 2024 to 2025 in the region of 20% kind of range. But of course, as I say, it is a dynamic market, and as silicon photonics and EML gains more adoption, we could very well see some increases there. I'll also make another note as we look at this market. There's a strong development trend in China for EML and silicon photonics as well. So not only are we seeing this in the normal players, but a lot of the laser detector manufacturers in China that's deep on market are now taking a look at the EML silicon photonics market. So they all also want to enter into that market. So, you know, back to it, I've got a 20% year-over-year growth kind of figure in there, but it is dynamic and additional growth coming up.

Yeah, I agree.

All right, got it. And going back to the export restrictions, at least using gallium arsenide as a model, you had a pretty modest downtick after those were announced in Q3 of 23, I think, and bounce back pretty strongly over the next three quarters. I know the question's kind of been asked, but is that, you know, assuming you're able to, in the same fashion, secure the permits, is that something we might expect here? Could you see yourself getting back to, you know, these strong Q4 levels you just reported in Q2 or Q3?

I think so, Tim. So let me put some analysis cap on myself, okay? I think if you look at gallium oxide versus indian phosphide, in gallium oxide, honestly, we are the third in the world, and we are the smaller of the three, okay? And our market share is relatively small. But indian phosphide, I believe we're either number one or number two, okay? so I and also I think Gallia Indian phosphide is not a material which is easily replaceable we work with our customers sometimes two or three year to I mean 18 months to two years to qualify and we work into very details of what customer wants how we can deliver we have the capacity we have you know the order actually in hand so once we get the permit i believe we can deliver quickly and i think we can recover from what we have missed uh and some more as well but of course you know the the dynamics is that you know what's a geopolitical struggle between the two so i i think they'll i i hate to speculate there, but I think given the chance, I think our recovery for Indian foscois is probably going to be better than our recovery from the Ghanaian side would have been.

Great. Thanks very much.

And once again, if you would like to ask a question, simply press the star one on your telephone keypad. Your next... One moment, please. And your next question comes from the line of Dave Kang with B. Riley. Please go ahead.

Thank you. Good afternoon. First question is regarding germanium. So what's the plan here? Are you continuing to run this business or any thought of like maybe monetizing?

Well, yeah, germanium, it's a good question. I think there's a lot of the low orbit satellite opportunities in China. Actually, the demand is extremely strong. However, you know, the material, raw material prices went all the way to, well, this is renminbi, it's almost like $3,500 per kilogram from as long as $1,600 a kilogram. And the raw material was a major part of the cost of goods sold. So, you know, we view this not as a growth opportunity for us, But we obviously will start to manage or get into the market once the raw mature price gets down to a certain level that we can start make profit at this market, Dave.

Got it. And just wanted to dig in a little bit more on indian phosphide. Is it possible, I'm not sure you have the answer, but since you talked about photodetectors versus silicon photonics, What's the rough mix between those two?

Oh, it's hard to say the mix. I think the photo detectors team, what was the photo detector revenue we got from the Vixxel was around $5 million last year, right?

Yeah, I want to say that it's not quite 50-50. I want to say that we're seeing a little bit more on the laser side of the business. I'm talking the data center on the EML and the silicon photonic side. I want to say that we're looking at somewhere in the region of like a 60-40, maybe even a 65-35 split in favor of laser versus detector.

Yeah, but on the other hand, I think it's going to be difficult to say what's a detector, what's a laser, right? I mean a lot of these substrate we sell to they don't tell us what detector I mean some market for the VIXO pair they do tell us instead of for for detectors but most of the others they don't tell us right that's right like for example your lead customer I mean are they both uh for the detector as well as the Silicon Photonics customer or mainly Silicon Photonics?

That's mainly Silicon Photonics.

Got it. Our lead customer?

Yeah.

Yeah, I don't think they even use Indian phosphor as a detector in that device, in that transceiver. They're using Silicon Germania as a detector.

I see.

Got it.

That was it for me.

And I am showing no further questions at this time. I would like to turn it back to Dr. Maurice Young for closing remarks.

Thank you for participating in our conference call. As always, feel free to contact me, Gary Fisher or Leslie Green, if you would like to set up a call. We look forward to speaking with you in the near future.

Thank you. And ladies and gentlemen, this concludes today's conference call. Thank you all for joining. You may now disconnect.
