Thank you, Teal, and thank you, everyone, for joining our second quarter's earnings call. I'm sure many of you have read our second quarter investor letter, so my opening comments will be brief, and I would just like to highlight four items that really excite the Plug Power team. First, we had a record quarter in the middle of the pandemic, achieving over $72 million in gross billings and $1 million in EBITDA.
The third quarter will be 40% higher in gross billings, and we are projecting between $110 million-$115 million, with EBITDA between $9 million-$10 million. Our factory and service team will build and install over 4,000 GenDrive units and construct 10 hydrogen stations. Through the year, we are on target to achieve our goal of $310 million in gross billings and $21 million in EBITDA.
Second item that has me excited is that we took major steps in the second quarter to achieve our goal of producing 40 tons a day of green hydrogen by 2024 via the acquisitions of United Hydrogen and Giner ELX. United Hydrogen provides us the platform to build large-scale commercial hydrogen plants, and Giner ELX provides us the in-house capability to build and deploy electrolyzers for those sites.
Giner ELX is renowned for their PEM technology, and now coupled with Plug Power's scale in manufacturing, we believe Plug Power will drive the cost of PEM electrolyzer technologies below current day alkaline electrolyzers technology. With better technology, better cost, and a distribution network across Europe, Plug Power is well-positioned to leverage the planned 80 GW of deployment of electrolyzers in Europe and North Africa by 2030.
Third item, the success this year with the rapid growth in gross billings and EBITDA are moving to green hydrogen. That's provided us a clear path to achieve $1.2 billion in revenue and $250 million in EBITDA in 2024. For years, building customer relationships with Walmart, Amazon, Home Depot, BMW, and others while enhancing our technology and making strategic acquisitions has well-positioned Plug Power to continue to be the leader in building out the hydrogen economy.
The big news in our earnings letter is our gigafactory for making PEM stacks for fuel cells and electrolyzers. We are in the process of down selecting a location for this facility, and we are in discussions with multiple locations across the country. Our plans are that this will be the global showcase for PEM manufacturing in the world.
I look forward to telling you more about this during the Plug Power Symposium in September, when we hope to announce the location of this facility. Now, in closing, Plug Power is really unique. We built the first market for fuel cells in the world, deployed over 35,000 units, and by quarter end, we'll have 100 fueling stations up and operating by Plug Power.
We're a technology leader with our own MEA manufacturing capability, the leader in fuel cell and electrolyzers technologies, and our scalable ProGen fuel cell system can be used to build large-scale backup power systems and on-road vehicles. We have the competencies to build large-scale green hydrogen plants that can be cost competitive with fossil fuel-based hydrogen. They are our two latest acquisitions. We plan to be a large provider of green hydrogen, probably doing it with some partners.
Ultimately, when I look at it, who will use green hydrogen in the $69 billion hydrogen market today if green hydrogen is available at a competitive price? Finally, Plug Power is really unique. We're a leader in technology and the new energy economy for hydrogen. You couple that with a track record of real-life experience, and these two capabilities are a complete fit because they enable Plug Power to provide customers turnkey solutions. Paul and I are now very happy to take anyone's questions.
Our first question today is from Eric Stine of Craig-Hallum. Please proceed with your question.
Hi, Andy. Hi, Paul.
Hey, Eric. Good morning.
Good morning. I was hoping to just chat first on the gigafactory. That certainly is quite noteworthy, as you said in your remarks. Just any thoughts on what type of revenue level that supports and what type of investment, and I know it Well, it's early, but it sounds like it's quite advanced as well, but what type of investment you may need to make to make that happen?
Eric, I think there is some variables there. When I look at what revenue this will support, this will support well past our $1.2 billion target for 2024. I would expect somewhere around $2 billion in revenue, this facility will support. We're obviously in discussions with different localities to help support funding of this facility. I would tell you we've already have made some initial purchases of equipment and that we have a fairly clear layout for the facility. I think a good deal of it, how much ultimately it'll cost Plug Power, will have a lot to do with the negotiations we have going on with different states across the country.
Got it. Okay. I guess stay tuned on that one. Just turning to the guide. I know in the release you said you reaffirmed it, but in your commentary, it sounds like you are including. Is it right that you're including United Hydrogen now and saying $310 in revenues, or I'm sorry, in billings, and then $21 million in EBIT? Curious if it's United Hydrogen's inclusion or if there may be something else that you are including in that number.
No, Eric, when we made the announcement of the acquisitions was when we increased the targets, and that was included in the increased targets.
I guess on the last, yeah, when you made those acquisitions, to me at least, it was a little unclear whether you had officially done that or not. That's helpful. Maybe last one for me. I know, obviously, as the hydrogen strategy takes shape, your goal with United has been to insource as much of that hydrogen as possible. Just, I know it's still early, but curious on what that looks like and what the potential margin uplift will be as you continue to do that.
Looking at where we are, Eric, if you take a snapshot at year's end, we'll be about 40 tons of hydrogen usage, and that United Hydrogen, we expect by the middle of the second quarter of 2021, about 8 tons of hydrogen with our expansion of that facility will be used in the Plug Power network.
If you take a look at that moves essentially about 20% of our hydrogen from a buy resell model to a sell model and puts margins for that portion in the 35% range. It's a big step in improving the hydrogen margins. Obviously, we're looking at building green hydrogen plants in the near future with either hydropower, wind or solar, or all three.
Okay. Got it. Thanks.
Okay. Thanks, Eric.
The next question is from Stephen Byrd of Morgan Stanley. Please proceed with your question.
Hey, good morning. I hope you all are doing well.
Stephen, it's good when you're shipping a lot of product, and business is going in the right direction, so I'm doing well.
Excellent. Pretty exciting updates. Obviously the gigafactory is a really interesting development. I guess I wanted to explore the positives related to that, as well as just sort of addressing some of the questions on risk that we may get. On the positive side, I guess I wondered if you could address, as I was thinking, if you're the first to achieve very large scale, just in terms of the cost advantage you see from reaching the kind of scale that we're talking about, really quite massive.
On the flip side, wondered if you could also address sort of your latest thinking on there are a number of players out there who'd like to produce hydrogen. There are a variety of technologies. Some do look to be fairly low cost. I know you've talked about this before, but just wanted to get your latest thinking on sort of your competitive advantages relative to others.
Sure. I think there's a couple items when it comes to green hydrogen. I think, first and foremost, the experience of building a plant is actually very limited around the world at scale, and that's something that United Hydrogen has achieved. Two, it is clear to me that the cost of renewables as they continue to go down, that hydrogen generated from renewables will be, on a variable basis, cost competitive with natural gas-generated hydrogen.
A real distinct advantage. My view is that I've looked at many of the carbon capture technologies, and I fundamentally believe the basic cost structure and simplicity of using renewables such as wind, solar, and hydropower to create hydrogen is a much more cost-effective approach, especially over the next decade. When we look at that market, we see many opportunities.
We actually have looked at over 20 sites for places we can build plants with partners as well as on our own. If we can source renewables at $0.04 a kilowatt hour, we're extremely competitive with gray hydrogen today.
That's a great update. In terms of the gigafactory, I know you, at this point, really can't give very much detail on the financing, but I'm guessing that there are a variety of incentives that are possible approaches to financing, such as sort of the end usage of your net balance sheet's probably lower than folks might be concerned about. Is that fair to say that just generally there are probably a lot of tools in your toolkit in terms of how you think about financing that?
Absolutely, Stephen. Like many of these, if you look around the world, here in New York, you had the Cree factory that went out in Rochester. You have activities, obviously, the different facilities Tesla has built.
Hydrogen, as many of you know, people are recognizing as critical to the long-term clean energy economy, which is much dependent on customer demand and companies like Amazon positioning to meet their 2040 sustainability goals, there's many applications that hydrogen's the only solution. I think a company like Plug that built the first market is very attractive to different jurisdictions who would want to support the building of such a facility.
Great, maybe just very quickly, one last question. We do get questions just on the long-haul transportation, long-haul trucking market in terms of the relative advantages of fuel cells versus battery systems, and I know you've talked about that in great depth on numerous occasions. I just wondered if you could give us your latest thinking on sort of the reasons you see advantages in terms of fuel cell systems for long-haul transportation.
Sure, Stephen. If you look at it, and I guess one of my fundamental beliefs is that electric motors eventually will be a better cost solution than internal combustion engines. It's a question of how you power. As many people know, fuel cells have three advantages. One is fast fueling, which can be at least 5x to 6x faster than electrical charging. I think the second area is that ranges of up to 500 mi are certainly doable and possible with Class 8 trucks. Third is that, and this is the one that when you sit with people in the vehicle industry, it's the packaging density.
Now I have a chart that I show that was put together by DHL that shows that essentially after about 100 km, the density of fuel cells and batteries is about the same, about the physical size they take up. From that point on, batteries grow at a 10x rate. Even if there's improvements in batteries, there also will be improvements in fuel cells. DHL, for any trucking beyond 120 mi, 130 mi, for example, is a clear believer that because their business isn't moving batteries around, it's moving packages for customers, that fuel cells are a distinct advantage because they just don't take up as much space as batteries will in a truck.
All right. Thank you.
You're welcome, Stephen.
The next question is from Jeff Osborne of Cowen and Company. Please proceed with your question.
Hey, good morning, guys. Couple questions on my end.
Morning, Jeff.
Good to hear from you.
Yeah.
Hey, Andy, can you just talk about the cadence of the year? Certainly the third quarter looks phenomenal relative to the trends of the past, the third and the fourth quarter. Is that an impetus of retailers having to shift to more online versus in-store business? I'm just trying to understand the cadence between 2Q to 3Q, the uptick of 40% that you talked about, and then the downtick in 4Q.
Sure. Jeff, I guess on the first item is that when I spoke about the second half of the year back in January, I said 35%-40% of the business will be in the first half, the rest would be in the second half. There has been some switches where I saw a slowdown in the auto market where we support companies who manufacture cars.
I did see a corresponding uptick in retail. When I look out to the fourth quarter, I've been doing this for a dozen years now, Jeff. I've become very cautious about upping those numbers until I'm 100% guaranteed. This quarter, I'm 100% guaranteed. In the fourth quarter, what I have today is all in house. I think in November, we may give some additional guidance there.
I really think what happened here with COVID, I think you're going to see an impact in 2021. We're still working through our numbers in 2021. Our visibility in the retail sector for both food retail and internet retail, the business will just get stronger next year. I would think in the November timeframe, I'll be able to give you really good guidance for then.
Okay. That sounds great. Can you just touch on what you're seeing in the trucking market? I think in the past you had talked about working with four potential partners, one in earnest. You've obviously announced Lightning eMotors. I didn't see much of an update in the shareholder letter on motive applications in general. Can you just broadly touch on that?
Sure. When I look at it, Jeff, as I mentioned previously, it's probably early next year, mid next year where the four manufacturers we're working with for scale manufacturing, we expect to have an announcement. It's possible, quite honestly, that there could be one a good deal sooner than that. As I said before, we expect to be putting vehicles on the road.
It's small scale this year. I know at two sites in Europe and additional site in the U.S. The business is evolving and growing, and I have to say, I'm quite confident about one of the partnerships that I would expect that we will have more to tell you about sooner rather than later.
Look forward to that. My last question was on the Asda deal. Can you just touch on that? There was reference to the initial site. I didn't know how many sites that they might proceed with maybe next year or what the potential was there relative to Walmart and other partners on the domestic side.
Sure. We are working with Walmart now much more on a global basis. In the U.K., there's between 10 to 20 opportunities. They have about a 15% food retail market share. I think that how you have to think about our business today with Walmart is not just the domestic North America business, but global activities. Walmart has facilities around the world, and I think our ability, especially during this pandemic, and I think the pandemic helped the Asda deal, that I would expect an expansion of our relationship, not only in North America, but globally.
Just a quick follow-up, can you use the same financing structure globally, or does it have to be domestic because of the tax equity?
The finance strategy with Walmart globally will look more like our normal customer relationships.
Excellent. Thanks so much.
Okay.
The next question is from Jed Dorsheimer of Canaccord Genuity. Please proceed with your question.
Hey, thanks. Congratulations on another good quarter and some great milestones.
Well, thank you, Jed.
You're welcome. I guess, first, I just want to dig in, Andy, on, you mentioned in terms of 2021 and COVID, although the way that you're speaking about COVID is actually the inverse of what most other companies are referring to. Maybe if you could just dig in and unpack a little bit, sort of how you see this helping the business and kind of accelerating and pulling things in.
Sure. Jed, when you think about our value proposition, especially in material handling, but it certainly translates in other applications, it has a lot to do with moving goods faster and moving goods more productively. When you look at my base business in those areas, it's with food retail, and it's with Internet retail.
If you think about how many people now are more eating at home and how many people now are buying packages online, I think you've seen the growth that my biggest customers have had, and I think across the board, we are in the right segment for the future. We're involved in segments which are associated with the future of logistics, and we're with two of the biggest players, the largest Internet retailer in the world and the largest food retailer in the world.
Both of them recognized during this crisis that, in many cases, and I think that it would've been very difficult for them to meet their customers' needs if they didn't have fuel cells moving products around. They saw the difference in the facilities that had fuel cells versus the performance of facilities without fuel cells. I think that's really the underlying reason, Jed, why we've been successful.
That's helpful. Thanks for outlining the value proposition. I guess maybe as a segue or continuation, as we think about those customers that are installing on-gen or on-prem generation for the material handling, as we think about that $1.2 billion in the context of kind of getting into the next application, could you maybe update just on where you stand for sort of that Class 2 through Class 6 trucking application, and whether or not we should expect to see an existing customer that leverages the on-prem first in there, or you think that it may happen differently?
I can tell you that we are making modifications to fueling stations as we speak with one of our present customers to be able to do outdoor fueling of Class 6 and Class 8 trucks. We certainly plan to participate in that for the on-road vehicle, sector, too. We're really unique. We've built and operate now over 100 fueling stations, which you can drive from Lewiston, Maine, all the way out to the West Coast of California, and there's fueling stations built and operate by Plug Power along that whole path.
We just see that as an opportunity to leverage and help us in the vehicle market, as well as help us in our quest to build out our green hydrogen business. I think there's a lot of positives in those areas, and I think we're well-positioned with our present customers to do those types of deployments.
Great. One last high-level question for me. By the way, congratulations on getting that footprint in the U.K. If I look at how the narrative's somewhat shifted over the past year or so here, you really are talking a lot more about green hydrogen and we see the beachhead into the European markets here. I'm wondering if this is a harbinger of more things to come with your expansion into Europe, how much of that is baked into that 1.2 or whether or not that has more to do with the $2 billion number that you threw out today.
I think when you take a look at our plan that we rolled out in the past year, in September, it was relatively light when it came to Europe. I think we've spent a good deal of time building relationships in Europe over the last five years with people like BMW, Daimler, IKEA, now Asda, and Carrefour. That has given us viability in Europe. One of the exciting aspects of the activities with Giner ELX is that they have built interesting partners across Europe for the future hydrogen economy, and we're thinking through ways of leveraging that.
Both on the green hydrogen side and on the vehicle side, there are a good deal of discussions going on with potential European partners. Europe is What do I spend my day on? Green hydrogen is certainly one of the big items, but the opportunity in Europe and the gigafactory are right up there.
Great. Thank you.
As a reminder, if you would like to ask a question, please press star one on your telephone keypad. Our next question is from Colin Rusch of Oppenheimer. Please proceed with your question.
Thanks so much, guys. I guess I have two around the revenue. One, you talked about $290 million of bookings in place previously. Can you give us an update on that number as we think about the full year? Then secondarily, as you look at the 3Q guidance, how much of that is hydrogen sales separate from the self-consumption of hydrogen with United Hydrogen acquisition?
Sure. A lot of the hydrogen sales help me on the margin front now, since I have been moving already hydrogen to Plug Power. Colin, we have everything in-house for this year to achieve the $310 million, and looking at opportunities to expand that. We're well-positioned for next year to continue on the growth rates we have had.
As I mentioned, I would expect that in the November call, we'll be able to share more of those projections, but it's in line with our goals to get to $1.2 billion. Hydrogen itself is probably between Giner and United, probably represents about 6%-7% of our revenue in the third quarter. We'll have, of course, the additional hydrogen we normally use, and it'll be in line with our normal run rate.
Excellent. Can you give us a sense of where your fuel margins are going to end up here in the third quarter? As we think about that through the balance of the year, that's been a drag on the overall profitability, but I'd love to understand this order of magnitude and the immediate impact.
I'm sorry, Colin, I didn't hear your question.
The hydrogen fuel margins.
Sure
hydrogen integration. Can you give us a sense of immediate impact and how much more benefit we'll see over the next couple of quarters?
I'll let Paul take that one. Paul, do you want to take that question?
Yeah. I think you're definitely going to see accretive improvement, Colin, because of the acquisitions and the roll-in. As Andy outlined, the big progression and accretion will really start to kick in next year as we start to really leverage United Hydrogen and internally sourcing as well as growing the electrolyzer platform. I think it'll be directionally consistent with the first half, but what you see some improvement in Q2, and you're going to see some continued improvement in Q3 and Q4 as we progress through the year.
Great. Thanks so much, guys.
Thanks, Colin.
The next question is from Craig Irwin of ROTH Capital Partners. Please proceed with your question.
Hi. Good morning, and thanks for taking my questions.
Good morning, Craig.
Hey, congratulations on some really impressive results here.
Well, thank you, Craig.
When I looked up the Palm Springs, California refueling station for United Hydrogen, it's obvious that the infrastructure credits are financially beneficial to you. They have the right to generate Low Carbon Fuel Standard credits from the sale of green hydrogen. Would it be logical to expect that the refueling facilities for trucks that you're working on would likely be in markets where they would be eligible for similar credits? What do you think about the potential for your truck product to be eligible for ZEV credits when you sell those commercially to your customers?
I think that's a real good question, Craig. I think when I talk to our big customers today, obviously because of both the ZEV credits and the LCFS credits, I've seen numbers that the cost to generate the hydrogen with those credits could be lower than $1 a kilogram, which makes it extremely attractive, when you start thinking about even versus electricity.
That site we own there, I think could be a combination of fueling station that could complement the distribution centers in California, as well as a depot to drop off liquid hydrogen for Southern California. Both of them. I really am amazed you found out about that. Both of them are kind of items we're focusing on today.
Excellent. Just from a per kilowatt basis, is it fair to assume that your fuel cell trucks will obviously have much greater ZEV credits per unit, even on a per kilowatt basis than a truck? Is that a fair assumption?
That's a fair assumption, Craig.
Excellent. Most of my other questions have been answered, so I apologize for one that almost feels backwards looking, although it's important.
Okay. All right.
for this revenue trajectory, right? Your pedestal customers, Andy. Most people are focused on the trucks now, right? You've talked about adding a few more pedestal customers in electric forklifts. I think your business there is very well-validated at this point. Can you update us on the breadth of potential customers you could add? Are we still really talking about two or three or maybe more now? How are those conversations going now that those potential customers are seeing 40% of the groceries in the U.S. moved on your forklifts in the first half?
Craig, we will announce another pedestal customer this year. There are discussions going on with six or seven of those customers. An interesting mix between North America and Europe. I think, as you know, all the interest for fuel cells in Europe, along with the fact that we don't have as many units in Europe, that customers saw similar results. I have not forgotten that when you take someone like Amazon, where there's large opportunities across a variety of applications.
The key is to make sure we continue to provide them good products and good values in material handling. That's what's built our credibility. Look, if you go around, it is to brag. I don't think anyone has the demonstrated credibility who's a pure player in the fuel cell space that Plug has today. It's because we've done it over the years, and I think it really does uniquely position us.
Great. Well, congratulations on this progress, and thanks again for taking my questions.
Great. Thanks, Craig.
The next question comes from Sameer Joshi of H.C. Wainwright. Please proceed with your question.
Good morning, Andy, Paul. Thanks for taking my question. Most of my questions were answered.
Good morning, Sameer.
Good morning. Most of the questions were answered, just one question. We noticed nicely that the Giner deal includes a lot of earn-outs, and that had led us to believe that there will be some technological improvements, and earn-outs based on that. It seems from the commentary that most of the benefits you're planning to derive is from scale that you bring to Giner. Are there any membrane improvements or catalyst improvements that are in the R&D phase at Giner that should help you in the future?
Absolutely. I see that we have a real clear roadmap for Giner. First, there's process improvements, which will help dramatically reduce cost, but it also helps us to increase the amps per centimeter squared. Plug is a leader in that today. By 2024, with the work that the folks there are doing, we would expect that we'll be twice as good as the European goals for 2030.
If you look, I would encourage people to go look at Giner's history with NASA, with General Motors, with the DoE. I think they have $10 million of development projects, mostly associated with Giner, with the DoE. They continue to improve electrolyzer stacks.
I can tell you when I go around talking to people in Europe, everybody in Europe knows who makes the best stacks, it's Giner from a technology point of view. They have a roadmap clearly spelled out over the next four or five years, how we're going to double the current density, improve the efficiency, and continue that leadership position and supported by our own capabilities as well as I think that the relationship that they've developed with the DoE and national labs over years, and NASA, really well positions our technology for continued improvement. That was a good question.
Thanks for that. Thanks for the commentary, though. It was really helpful. One of the other clarifications we would like is on United Hydrogen expansion. For the immediate expansion, is there any green aspect for that plan?
Sure. If you look at that plant, today, it's actually fed by a waste stream. Right off, you're taking waste stream from an Olin plant, which is just waste hydrogen, which would just be burned off into the air. Additionally, we're looking to convert the liquification to renewable electricity via TVA. That's really just clarification. That plant itself, we think can have CI scores which are below 70.
The plans we're looking to grow past that and just so I should mention also, we've also been thinking about how we deliver hydrogen, and you could expect the liquid hydrogen that Plug Power will provide, ultimately will be delivered with hydrogen trucks. That, again, the combination of two can allow us to get the CI scores into zero, if done right.
Understood. Thanks for that clarification as well. We'll take our questions offline.
All right. Thanks, Sameer.
The next question is from Christopher Souther of B. Riley FBR. Please proceed with your question.
Hey, good morning, guys.
Good morning, Chris.
Thanks for taking my questions. I just had a few here on one-time items. Could you break down that $8.3 million? Looks like it was mostly SG&A related to acquisitions, but curious how much the COVID impact was there on the cost of revenue, and what costs we should expect to remain for the either cost of revenue or SG&A for the rest of the year related to that.
Paul, do you want to take that?
Sure. I would say in terms of the amount that's within that charge, it's probably 10% or less, to be honest. The majority of it is really associated with all the acquisitions and the debt restructuring that we did. There was a lot of events there, and there was a lot of cost associated with those things.
Got it. Okay. On the systems and infrastructure margins, down sequentially, is that just related to the larger mix of infrastructure? Is that kind of a sub 30% kind of run rate, something that we should consider for the rest of the year? Do you think that should go back above 30%?
Yeah, I think what I've talked about in the past is when you look at the different product lines on the fuel cells, routinely, we've disclosed that we've been at that 35% or higher gross margin on the infrastructure. We're in the mid-teens. We've done 100 of them, and it's hard to get that to where it needs to be with only 100, but getting to mid-teens is pretty impressive, and we expect that to continue to progress north. Could get up into 20% in the back half with volume and leverage. I think you're going to see directionally that overall rate continue to improve in the balance of the year and onward into next year.
Understood. The last one, on the stationary and backup power end market, seemed like the focus is going to be on data centers. What has the traction been like with new customers there? Are there any existing customers that might be looking at the product, and can you just talk about how that end market's going?
Sure, Chris. It's interesting, first and foremost, one of my largest customers today is a leader in the data center space and has been very helpful in the design and the development of that product. I think our offering is really unique and that the business interest is so high that I've actually named a VP of sales for that division who has extensive experience in data centers. I would say that if you name a major data center provider, both an infrastructure company as well as the operators, I think we're in discussions with all of them with our activities.
The products are really cool and I think the work we've done developing our ProGen stack has really been leveraged in building out our megawatt style plant. One last item I like to add, people may not think about it, but I always think about systems. How you support hydrogen for backup power in these systems, one really needs to think about.
The fact that we're beginning to be able to move, and we move a great deal of hydrogen around already, even before our acquisitions. I think there's very few people who could actually provide these large data center providers a turnkey solution so that they wouldn't have to worry about how they fuel it.
I would encourage people to, when they think about large-scale backup power, you have to always think about hydrogen, and Plug is uniquely positioned to support the hydrogen needs for these kind of applications.
That's very helpful. I appreciate the color. Thanks.
Great. Well, thank you, Chris. I believe that's the last question. I would like to highlight the Plug Power Symposium's coming up. There's a registration. This is open for everybody. It's a virtual event. I think it'll be incredibly informative. I know we're lining up some interesting speakers, plus you'll have opportunity to hear more details about our business from some of my coworkers and that this is open to all. There's a link in the investor letter you can click on, as well as there's a online registration on our website. Please take the opportunity to register and look forward to talking to everybody then. Thank you now.
This concludes today's conference. You may disconnect your lines at this time. Thank you for your participation.
