Thank you, David. Welcome to Viavi Solutions Q4 and fiscal year 2022 earnings call. My name is Sagar Hebbar, Head of Investor Relations and Corporate FP&A. Joining me on today's call are Oleg Khaykin, President and CEO, and Henk Derksen, CFO. Please note this call will include forward-looking statements about the company's financial performance. These statements are subject to risks and uncertainties that could cause actual results to differ materially from our current expectations and estimations.
We encourage you to review our most recent annual report and SEC filings, particularly the risk factors described in those filings. The forward-looking statements, including guidance we provide during this call, are valid only as of today. Viavi undertakes no obligation to update these statements. Please also note that unless we state otherwise, all results except revenue are non-GAAP.
We reconcile these non-GAAP results into our GAAP preliminary financials and discuss their usefulness and limitations in today's earnings release. The release, plus our supplemental earnings slides, which include historical financial tables, are available on Viavi's website. Finally, we are recording today's call and will make the recording available by 4:30 P.M. Pacific Time this evening on our website. I would now like to turn the call over to Henk.
Thank you, Sagar. Fiscal Q4 2022 set an all-time record for Viavi revenue and a Q4 record for non-GAAP profitability. Fourth quarter revenue came in at $335.3 million, up 7.8% year-over-year, exceeding our guidance range of $315-$329 million. Growth was primarily driven by improved demand for our core OSP and 3D sensing products. Viavi's operating profit margin at 21.3% was within our guidance range of 21%-22%, improving 50 basis points year-over-year. EPS at $0.24 met the high end of our $0.22-$0.24 guidance range and increased 9.1% from $0.22 in the prior year. A combination of strong operating performance and the impact of an improving capital structure.
The fully diluted shares outstanding at the end of fiscal Q4 2022 of 231.3 million shares decreased from 241.9 million shares in the year-ago period. Substantially the result of refinancing our convertible debt while continuing to execute on a share repurchase program during fiscal 2022. The outstanding dilution resulting from the remaining convertible notes was 1.6 million shares during the Q4 compared to 10.4 million shares a year ago. Moving on to our reported Q4 results by business segment, starting with NSE. NSE quarterly revenue at $246.2 million, up 4.1% year-over-year, was within our guide range of $240 million-$250 million. A new quarterly record in this business segment.
Within NSE, NE increased 4.5% from a year ago to $222.2 million, reflecting continued strong demand for our wireless and optical lab and production products. SE revenue at $24 million was flat year-over-year, albeit at an improved product mix. NSE gross profit margin at 64.9% increased 150 basis points year-over-year. Within NSE, NE gross profit margin at 64.2% increased 110 basis points from last year, primarily a result of leverage on growth and favorable product mix. SE gross profit margin at 71.3% increased 580 basis points year-over-year. NSE's operating profit margin at 15.1% was slightly below our guidance range, albeit flat year-over-year.
Higher variable sales commission costs on strong bookings performance during the quarter was offset by gross profit margin expansion. Now turning to OSP. Fourth quarter revenue at $89.1 million was up 19.8% from a year ago and improved sequentially by 5.2%. Revenue exceeded the guidance range of $75-$79 million due to better than expected demand for anti-counterfeiting products during the quarter. Gross profit margin at 55.9% decreased 160 basis points year-over-year, driven primarily by raw material costs and startup costs in our new Arizona facility. Operating profit margin at 38.6% was within our guidance range of 38.5%-39.5%. Although down 20 basis points year-over-year, a result of the aforementioned gross margin factors offset by disciplined OpEx management.
Moving to our fiscal 2022 full year performance. Despite the COVID-19 pandemic related supply chain issues and inflationary pressures, Viavi was able to mitigate much of the impact, resulting in a strong finish to a record of $1.3 million, up 7.8% from fiscal 2021. NSE reached a record revenue of $949.1 million, up 13.3% year-over-year, well within the range of our long-term goal. OSP at $343.3 million saw a modest decline of 4.9% in revenue compared to record levels in 2021, but still exceeded the high end of our 2022 goal provided in 2019.
Viavi's full year 2022 operating profit margin at 22.2% expanded 110 basis points and exceeded the high end of our goal of 21% by 120 basis points. Within our NSE segment, operating profit margins expanded 460 basis points from 11% in 2021 to 15.6% in 2022 due to leverage on revenue growth combined with disciplined OpEx management. Within our OSP segment, operating profit margins reduced from a record level of 44.7% in 2021 to 40.5% in 2022, a result of lower revenues in combination with higher raw material costs.
Full year 2022 EPS at $0.95 increased 14.5% or $0.12 from $0.83 in 2021, and is ahead of the high end of our goal of $0.90 for 2022, a result of operating performance and an improved tax rate. Now turning to the balance sheet. At the end of fiscal Q4 2022, the ending balance of our total cash and short-term investments was $565 million, down $139 million compared to a year ago, mainly a result of refinancing 57% of our convertible debt with longer notes at a favorable rate. During 2022, we generated $178 million in operating cash flow and deployed $73 million or 5.6% of revenues towards capital expenditures, resulting in $106 million in free cash flow generation.
We were able to buy back $45.5 million in common shares under the 2019 repurchase program and invested $8.3 million in M&A activity. Looking at just the Q4, operating cash flow was strong at $73.6 million, an increase of $11 million compared to $62.6 million in the year ago period. The increase is a result of higher operating income coupled with benefits from supply chain investments made early in the year. In addition, we invested $19.1 million in capital expenditures during the quarter compared to $25.4 million in the prior year as we progress towards completion of our Arizona production facility. As you may recall, we had targeted the reduction of our 2023 and 2024 outstanding convertible notes to continue to improve our capital structure.
During the first three quarters of 2022, we redeemed approximately $370.6 million of these notes from the original $685 million in principal value. In the Q4, we completed transactions to extinguish an additional $22.4 million in principal value of convertible notes at a total reacquisition cost of $27.2 million, bringing the principal value of our combined convertible notes outstanding to $292 million at the end of fiscal 2022 or 43% of the original principal value. During fiscal Q4, we repurchased 2.1 million shares of common stock for $28.9 million under the 2019 repurchase plan. The remaining authorization under the 2019 repurchase plan is $67.3 million. Now on to our guidance.
We expect the fiscal Q1 2023 revenue to be approximately $324 million ±$7 million. Operating profit margin is expected to be 21.4% ±70 basis points, and EPS to be in the range of $0.22-$0.24. We expect NSE revenue to be approximately $236 million, ±$5 million, with operating profit margin at 14.5% ±50 basis points. OSP revenue is expected to be approximately $88 million ±$2 million, with operating profit margin at 40% ±100 basis points. Our tax rate is expected to be approximately 16%-17%, and we expect other income and expenses to reflect a net expense of approximately $6 million.
Share count is approximately 232 million shares based on current stock price levels, and includes the dilutive impact of approximately 2.5 million of the remaining convertible notes. With that, I will turn the call over to Oleg.
Thank you, Henk. I'm pleased with Viavi's performance during the fiscal Q4 2022, resulting in a record quarterly revenue and profitability. We have also delivered an all-time record revenue and non-GAAP profitability for the entire fiscal year 2022. In addition, we have also exceeded the high end of our 2022 profitability goal set during the 2019 Analyst Day, despite significant headwinds from COVID and inflationary pressures.
The NE segment achieved the new revenue high in fiscal 2022, with both fiber and wireless growing double digits year-over-year, benefiting from strong investments in both service providers and hyperscalers looking to upgrade their networks. Despite the supply chain headwinds and inflationary pressures, we executed well on our strategy, growing revenue, profitability, and gaining market share.
In the fiscal Q4, fiber revenue growth was driven by fiber to the home deployment, 400G network and data center upgrades, and accelerating market adoption of 800G and PCIe 5.0 technologies. The 5G wireless demand also continued to be strong, driven by investments in O-RAN and fronthaul wireline network expansion. Fiscal Q4 also saw very strong NEM bookings, resulting in a seasonally stronger Q1 backlog and demand visibility. The SE business revenue was flat year-over-year for fiscal Q4 2022.
That said, the annual SE revenue grew 13%+ year-over-year, increasing our confidence in the revamped data center and assurance strategy and product. We expect continued strong growth in our SE business during fiscal 2023. Now turning to OSP. The OSP business segment delivered better than expected revenue and profitability, with revenue exceeding our guidance range.
Our fiscal Q4 anti-counterfeiting product revenue was up 27% year-on-year, driven by a combination of global fiscal stimulus and inventory replenishment. Looking ahead, we expect Q1 2023 revenue to be roughly flat to Q4, with lower anti-counterfeiting demand being offset by stronger 3D sensing. To recap, in fiscal year 2022, we successfully executed on Viavi's growth strategy that we have outlined during September 2019 Analyst Day and have exceeded our non-GAAP profitability and EPS targets.
The major highlights include NSE business segment achieving 13% growth in revenue and 60% growth in non-GAAP operating margins for fiscal year 2022. We're proud to have successfully executed despite the global pandemic, supply chain headwinds, and inflationary pressures. The OSP business exceeded our three-year strategic goals for both revenue and profit.
Lastly, we have successfully revamped our product portfolio to leverage secular trends and expand our TAM, positioning Viavi for continued revenue growth, increased scale and profitability, and market share gains. As we kick off our next three-year strategic plan, we invite you to join us at the Analyst Day event in Boston on September thirteenth, where we will outline our strategy and goals for the next three-year cycle. We hope to see you there. There will also be a live webcast of our presentation.
We'll provide additional information regarding the event over the next 30 days. In conclusion, I would like to thank my Viavi team for another quarter and fiscal year of strong performance and express my appreciation to our supply chain partners, customers, and shareholders for their support. I will now turn the call over to Sagar.
Thank you, Oleg. David, let us begin the question and answer session. We ask everyone to limit discussion to one question and one follow-up.
Thank you. At this time, I'd like to remind everyone in order to ask a question, press star then the number one on your telephone keypad. We'll pause for just a moment to compile the Q&A roster. We'll take our first question from Alex Henderson with Needham & Company. Your line's open.
Oh, great, thanks. Nice quarter, guys. I was hoping you could talk a little bit about the split between 3D sensing and the counterfeiting products in the quarter. My assumption is that 3D sensing is around $15 million or so in the quarter, and that the upside was heavily skewed to that 20% kinda jump in the security products. I'm assuming when you look out to the 2022 to 2023 window, that we revert back to is that set of standardized $60 million a quarter baseline in OSP. First of all, is that correct? You know, second question is really around the currency exposure and the mix of business internationally.
Can you talk about, you know, what's going on in your EMEA business, which was down substantially and, you know, obviously you made that up with very strong, domestic growth?
Okay, you asked three questions in one. Okay. Let's really just do one. Now, you wanna answer-
Sure. Your first question was the mix between 3D sensing and what we call core OSP. I think your numbers are pretty close, actually slightly better on 3D sensing than $50 million for the Q4, so you're pretty close. Then I think your follow-on question was on the outlook. Yeah?
The outlook, I think, you know, I guess first on OSP, I mean, we're going to see some pullback in the anti-counterfeiting demand, but we also have a stronger demand on 3D sensing. Net-net, it's kinda ends up being a wash and the remainder of the business staying fairly steady, you know, quarter over quarter. In terms of Europe, you know, the Europe business, I mean, was not that. I mean, clearly summer is a little bit seasonally weaker 'cause a lot of vacations. We continue to see Europe being healthy, although, you know, the challenge in Europe has been more, you know, the European currency has devalued against the dollar. In the relative terms, our products have gotten more expensive.
You know, we continue to see pretty strong demand from European NEMs and from service providers, many of whom are in a multi-year fiber to the home deployment, and that business continue to be pretty robust. I mean, clearly, you know, we're all reading the same news and you know, Europe is, you know, they are expecting some headwinds, and we are well prepared for that. At this point in time, our European business is continues to be fairly robust. I guess it's really driven more by a multi-year investment cycles that are just ongoing. It's not really spot purchases or anything like that.
Oleg Khaykin, we're reading the numbers correctly on your slide deck. It was down 22%. Is that mostly currency related?
I guess it comes down to where we ship the anti-counterfeiting pigments, whether they go to Europe or some other geography. So yeah. I mean, so, I think, you know, on the NSE side, I don't think we have that much variability, and
there's a little bit more project related.
Yeah
... Alex, on the NSE side in our wireless and lab business, not so much an OSP issue. There was a little bit of FX translation that drove the year-over-year down. That number was about $5 million for the quarter, purely FX translation on a weaker euro or stronger US dollar.
Good. I'll cede the floor. Thank you for letting me ask the questions.
Sure. You're welcome.
You're welcome.
Always.
Okay. Next we'll go to Tim Savageaux in Northland Capital Markets. Your line's open. Go ahead, Tim. Your line's open.
Yeah, sorry about that. Came a little quicker than I might have thought. Question on the network enablement side. A couple of things. I'll ask them both at once versus a follow-up, which is, you mentioned strong bookings and backlog in NE, maybe even unseasonably strong, which, you know, would be very much in line with everything we've been seeing across, certainly the fiber ecosystem, maybe 5G as well. And yet your guidance revenue is down sequentially. Can you reconcile that?
Looking at the year, fiscal 2022, you know, you grew NE revenue 13%. Now you had some very easy comps in the first half, and you grew it like mid-single digits, you know, 6% or so in the second. What's a reasonable growth expectation for the NE segment for fiscal 2023? Thanks.
Well, you know, we generally don't give annual guidance. I think, you know, all the worries around the recession aside, it should be a pretty healthy year. I would say probably, you know, maybe even seeing, I'd say mid-single digits%. However, I think given that, you know, I don't wanna jump ahead. I mean, right now we are not seeing it yet, but let's assume there is a recession and pullback. I'd say it may be slightly down or even up to flat year-over-year, depending on product line.
I think at this point it's probably too premature to talk about fiscal 2023 or even more calendar 2023 until we see how we exit this calendar year and whether or not a lot of the momentum we are seeing in Europe, North America and Asia will hold up or do customers pull back on their both R&D budgets as well as their deployment pace.
On the booking strength contrasted with the sequential revenue decline, anything to talk about there?
The bookings. Remember, a lot of our bookings is a book-and-ship within a quarter. Generally our September quarter is a seasonally weaker quarter in NE, but because we had such very strong bookings, it's coming in to be pretty close, I mean, to the June quarter. If you really adjust it, last year we had a big order that was shipped to a North American customer. If you adjust for that, it's actually coming in a stronger quarter on the run rate business with that one-off order excluded. We actually, you know, on seasonality-wise, because it's really, you know, a rule of thumb, our June and December quarter is the strongest quarter for NE business.
and March quarter are the seasonally weaker quarters.
Okay, thanks.
Okay. Next we'll go to Samik Chatterjee with J.P. Morgan. Your line's open.
Hi, this is Angela Jin on for Samik Chatterjee. I know you've mentioned you haven't really seen any sort of demand weakness from the recession, but are you seeing any of your customers, you know, aside from service providers and hyperscalers, you know, including them and aside from them, you know, delay any projects or rethink some of their investments in other 5G technologies such as, you know, industrial or automotive applications or enterprise spend in private 5G? Then I have a follow-up.
Yeah. I mean, we don't really do much with the automotive or anything like that. Most of our customers, aside from service providers, are in the wireless and fiber optic telecommunication space. I mean, to answer your question that we haven't seen the decline per se continues to be pretty strong.
Let's be realistic, I think you know, the slowdown hasn't really trickled down from the top to the engineering groups. Right now, they have a budget for the year, and they're spending it happily. Also what I've seen is even with a mild recession, companies that like get hit, you know, by slowdowns, you don't really see. They may see some reduction in production testing orders, but they generally don't slow down the R&D orders because the pro...
If anything, they try to accelerate product development during the dial cycle. I think, you know, I would say if there's really the pullback recession couple quarters, that business may just flatten out, maybe just goes down slightly on the eleven production space. The service provider, I mean, the programs are pretty much locked and loaded.
The question would be, are they going to take delivery in a quarter or they spread them out over a couple quarters? They may defer some of the deliveries and things like that. Given a lot of the kind of pent-up demand and, you know, clearly they have a lot of projects underway. I mean, we think the order momentum will continue to be relatively stronger as compared to other recessions.
Got it. For my follow-up, on the OpEx line, you know, generally you've been very disciplined about OpEx, but there it was a small bump up in this quarter, and so I was wondering if that was a reflection of the current inflationary environment, and if this could be sort of the new norm of OpEx level in the next few quarters, just given the current environment that we're in.
Well, I mean, our OpEx continues to be pretty disciplined. I think the bump up was really a function of commissions and bonuses paid out because we kind of work on a semiannual cycles. So that was for the first half where I think the bookings and the performance have been above the annual operating plan. We are making adjustment in the salaries, but nowhere near the inflation level. I think we're probably targeting somewhere in a 4% pay adjustment.
You know, that hits mainly North American OpEx, and then there's obviously adjustments in other regions, where in some cases the higher you know salary adjustments we're making have been more than offset by the currency devaluations vis-à-vis the US dollar. But I would say the biggest impact on OpEx increase would be in North America, where we're roughly doing about 4% increase this year.
Yeah. There may be a little bit of additional T&E that sort of roll into OpEx.
Yes. Well, it's coming back with travel. Yes.
That's right. Travel is coming back a little, but the inflationary impacts that Oleg spoke about. Think of OpEx going forward, not quite at the 41.2% that you saw in the Q4, but below that 41%, between 40.5% and 41%. I think that's the way to think about it going forward.
Great. Thank you.
Yeah. You're welcome.
Next, we'll go to Mehdi Hosseini with Susquehanna. Your line is now open.
Yes. Thanks for taking my question, and I promise to limit my follow-ups to two. Oleg, it seems like based on your commentary on OSP, the 3D sensing should see a meaningful year-over-year growth, September 2022 versus September 2021. Is that a fair assumption?
Well, actually not really, because if I look at the last year, if you remember, we had a very strong 3D sensing demand, and then our customer realized they didn't have enough chipsets to build the units because many of the other suppliers fell short. As a result, there was a big inventory rebalancing in the December quarter, and we saw our orders slashed in December, and then they recovered in the March quarter. I think this year it's a bit more linearized. I think the demand, the year-on-year, is roughly the same.
I mean, in fact, I mean, you may have a little bit better volume because of the deeper penetration of our 3D sensing into our multiple other platforms like handheld and the laptops and things like that, offsetting some of the ASP erosion. So overall, we think it's gonna be a pretty robust, a kind of flattish year-on-year, strong, a little bit stronger than June quarter. But if you look at September on September, fairly similar to a year ago. Where we are seeing decrease is the anti-counterfeiting pulling back.
Yeah.
From a year ago levels, where we hit close to $100 million last year, and it was really.
Yeah.
I'd say probably you're seeing about $10 million pull back on anti-counterfeiting, predominantly.
Sure.
All else remaining roughly the same.
Sure. Just to continue with 3D sensing, it seems like we're off to another strong smartphone cycle for the high-end application. Last year, your overall OSP revenues were down 5%. But given the strength of the high-end smartphone and other upgrade cycles coming, could you actually be able to have the OSP revenue in this fiscal year flat to up, or should we assume that it's going to trend more like a flat to down?
Well, remember the I think it's flat is more accurate because, you know, I mean, I have different people asking me, it's like, "Well, aren't the mobile phone sales going to be down this year?" I said, "Well, we're not really seeing a reduction in volume, but we cannot comment on number of phones because you also now have greater level of penetration. So instead of just one filter, you may have two filters per phone because you have more of these higher-end phones with the world-facing cameras and things like that." So I'm really just judging from the mix with we think adjusted for ASP erosions, roughly flat revenue this quarter.
Got it. Thank you.
Now, if the new product launch is very strong and there's a strong demand, we will most likely see that demand in the December quarter. Because remember, as I keep pointing out to people, our lead time is two weeks. If customer really wants to increase the volume demand, they'll, you know, we can turn it on within a very short period of time.
Okay. Speaking of lead time, I'm under assumption that there's no more supply chain disruption, components are available, for your NE business unit. Is that fair assumption?
I'd say it's a fair assumption for probably, you know, 98% of the devices. I think in the area you still have some challenges. I would not say less of a supply, but if you wanted to get a additional spot market deliveries, it's really FPGAs is still the only remaining.
Got it.
Thing that you need to watch carefully. Pretty much everything else, as I've been telling you guys for a year, by summer, we're really not seeing anything. If anything now going into this quarter, we're seeing lead times coming, pulling in much quicker. What used to be, let's say, 18 months, it becomes 12 months, then 6 months, and heck, now you can even get it on a spot market all of a sudden.
Okay. Just if I may, just a quick follow-up to this. A few quarters ago, you actually left some millions of dollars of revenue on the table because of the component shortages. You have been able to have a pretty robust revenue so far, beating your own guide. Should we assume that you were able to recapture those revenues that you left on the table or is that coming in the second half of the year?
Well, no, we've pretty much recaptured. Remember, when we said it, the revenue that slipped out, it slips out really by maybe a matter of weeks. You recapture it beginning of the first month. It was always like sub-$10 million, up to $5 million. I think at this point we're not really, I'd say, leaving anything on the table.
Okay. All right. Thank you.
Mm-hmm.
Next, we'll go to Meta Marshall with Morgan Stanley. Your line's open.
Great. Thanks. A couple questions for me. Maybe just on the anti-counterfeiting strength. You know, even as it's kind of pulled back from last year, it's probably remained stronger than you guys were thinking. I know that it's tough to get full visibility there, but do you like, is that inventory building? Is that reprints driven? Is there still stimulus programs kind of internationally that we should be thinking of? Or I guess we're just trying to get a sense of, like, what do you think is kind of a baseline run rate level of that business at that this point. Then I have a follow-up.
Yeah. I think the baseline for that business is now, I would say, like $58-$60 million. I think we're probably two to three quarters away from really everybody getting back to their reasonable levels of inventories that they carry. There's still, you know, some countries are further away from getting back to their normalized inventories, others are almost there. I would say, like, if I compare year-on-year, we had a lopsided delivery for a major customer last year. More came in in March, and less they pulled in from the June. This year, it's really been more back to the traditional demand, March and June. We had a pretty good, I mean, just as we expected seasonally, June quarter.
September quarter is usually a bit less, but you know, it's not materially less, but then increase in the 3D sensing more or less offsets that. I continue to see the anti-counterfeiting, I think now entering more of a steady state. I mean, a lot of these perturbations that we saw, you know, with COVID and stimulus and all that, it's kind of been subsiding, and now it's moving back towards traditional, you know, reprints, you know, release of the new notes and things like that. It's less of the stimulus-driven, it's more kinda basic business-driven. The reason we're saying it now, it's at the higher level, there's just fundamentally way more notes out there in the world.
To the extent recession is coming, you know, you know, we've seen different countries announcing plans to increase level of liquidity in their economy to. I think, nobody is doing anything crazy like dropping trillions of dollars from helicopters. We don't see anything like that on the horizon. It's more of a traditional demand profile.
Got it. That's helpful. Maybe, you know, you spoke to the NSE strength this quarter kind of being more wireless-driven. Just any commentary about cable or just, you know, what you're seeing from them, particularly after a pretty strong last couple of years.
Well, I would say really the two things that really driving is fiber and infrastructure wireless. We are seeing, you know, we have several major customers, and they kinda take their big deliveries in March quarter, June quarter, September quarter, that kind of thing like that. There is all the service providers. What we are seeing, aside from this kinda like our big three, four customers taking major deliveries annually, is what's even more encouraging to me is broadening of the customers. It's a combination of service providers establishing compliance labs as they try to drive more O-RAN adoption, right? Doing more of the fronthaul build out.
A lot of these new entries, you know, in the Open Radio Access Network, like the likes of Mavenir or Altiostar, and some of these other players like Rakuten or DISH Network getting into the space, cable companies getting into wireless, they're all buying these wireless equipment so they can emulate wireless network as they develop product. We're seeing a significant broadening of the wireless customer base. Maybe they will not buy tens of millions of dollars of equipment, but they buy millions of dollars of equipment. That's really driving the wireless. On fiber, it's you know two big drivers are the building out of fiber to the home that is in really early stages.
We now have multiple countries launching multiyear initiatives to connect most of their homes to fiber with the U.K. kinda leading the way. You know, now there's Italy and there's Germany, and of course, a lot of activity in the U.S. Now we are seeing similar type things happening in other European countries and in Asia. That's really the whole fiber to the home driving a lot of our fiber field instrumentation and the upgrade to the wireless networks and the telecom networks, you know, the fronthaul, the fiber. Just, you know, deeper fiber penetration into the network is driving a lot of the modules customers, and they're buying a lot of test equipment for production and development.
Of course, there's this whole migration to 400G and 800G that is, you know, driving high-end fiber equipment. I mean, between fiber and wireless, it's truly has been a great momentum overall.
Perfect. Thanks.
Mm-hmm.
Okay. That concludes today's question and answer session, and I'll turn the call back over to Sagar for any additional or closing remarks.
Thank you, David. This concludes our earnings call for today. Thank you, everyone.
This concludes today's conference call. You may now disconnect.
