  • Peter A. Smith - President, CEO & Director

  • Thanks, Keith and good afternoon everyone. Thanks for joining us to review a successful quarter. The company continued to execute on our key long-term focus areas of growth, margin expansion and meaningful bottom line improvements, despite continued supply chain and inflationary challenges. The Aviat team commitment resulted in revenue of $77.9 million, the highest quarterly revenue since Q1 of fiscal year 2016, driven by international growth of 25% versus last year. EBITDA margins of 13%, continued rock solid balance sheet and liquidity position increased pace of share buybacks. These results would not have been possible without the tireless dedication and execution of our operations team, engineering team and supplier partners in an incredibly challenging environment because supply chain has dominated the conversation over the past 12 plus months, let's address the environment from Aviat's perspective.

  • We experienced fewer supply interruptions, but we still experienced interruptions. Lead times did not improve, but fortunately, there were no high push outs. This is a sign of stabilization. The semiconductor allocation environment remains. We have invested to design out the most problematic suppliers. We remain subject to the risk of a supplier pushout and decommits late in the quarter, the most significant question, when does the supply environment get better? This is difficult to predict, but we feel that the environment will moderate in the April to June time frame and most hopefully all of the supply chain problems are behind us at the end of December.

  • Now let's move to the key highlights of the second quarter, which include our Multiband XD launch, high availability routing software, factory acceptance test success, strong and demand environment linked to RDOF, the infrastructure bill and spectrum auctions, EMEA growth, share buybacks. In the quarter, Aviat released a new enhancement to our multiband product line, Multiband XD or extended distance increases the reach of 10 gigabits per second links over distances up to 20 kilometers to support 5G and rural broadband applications.

  • To achieve comparable performance, competitive multiband solutions require up to 4x the hardware, making them costly and impractical for tower deployments, leaving high-cost fiber as the only option. Now with Multiband XD, operators can significantly lower their total cost of ownership by up to 90% when compared to fiber alternatives. Simply, this innovation makes Aviat more competitive versus fiber.

  • In the previous quarter, Aviat announced release of our new high availability routing software to improve the reliability of critical networks of all kinds. This quarter, we passed a significant milestone with the successful completion of Factory Acceptance Test or FAP, with a large US state customer. We replicated the entire state network in our facility in Austin, Texas and subject to the system to real-world stress and performance testing. The software performed flawlessly.

  • Aviat is one of only a few vendors offering high availability routing and we have a rapidly growing pipeline of deals for this new software. This opens an additional $300 million of market opportunity for Aviat. The environment for Aviat's offerings continue to improve. Let's touch on the Rural Digital Opportunity Fund, the infrastructure bill and the recent spectrum auction.

  • We remain well positioned for the rollout of the Rural Digital Opportunity Fund or RDOF as we track the RDOF winners, Aviat customers are earmarked for more than $3 billion of funding. In the quarter, we announced a new customer, Wisper Internet in this space. In November 2021, the US passed the bipartisan infrastructure legislation, which appropriates $65 billion for broadband infrastructure deployment. As a US company, Aviat is well positioned to participate in serving the 42 million Americans over broadband coverage or who lack contemporary bandwidth.

  • The FCC recently completed a $22 billion auction known as Auction 110 for the 3.45 to 3.55 gigahertz spectrum, the second biggest winner was DISH, our previously announced customer. As this spectrum is utilized, Aviat's backhaul business will be positively impacted. Our international growth of 25% was driven by our Europe and Africa regions. In previous earnings calls, we discussed improvements in the team and leadership. We have our first proof point internationally we're selling on value and Aviat's differentiation works.

  • Some highlights include a win with an important Southeastern European mobile operator and momentum with a UK private network customer. We see the preparations for several 5G deployments in Africa and we believe our portfolio has the best value proposition on the market for 5G in Africa. This preparation work suggests the future development of a favorable 5G demand environment.

  • We accelerated the pace of share buybacks during Q2, repurchasing almost $2 million of Aviat's stock and exhausting the previous Board authorization. As announced, the Board authorized a further $10 million share repurchase plan and we anticipate executing on the new plan opportunistically in the subsequent quarters.

  • Before turning the call over to David, let me provide a couple of additional observations and insights. First, this was a very good quarter and first half of our fiscal year. We remain focused and continue to execute and those collective efforts are reflected in our financial and operational results. We've continued to demonstrate our ability to grow and to take share of demand. Looking forward, we see 3 significant drivers, 5G, private networks and rural broadband and believe we are well positioned to capture significant opportunities with our differentiated products, software and services offerings.

  • With that, let me turn the call over to David to review our financials before coming back for some final comments. David?

  • David M. Gray - Senior VP & CFO

  • Thank you, Pete and good afternoon, everyone. During my remarks today, I will review some of the key second quarter and first half fiscal 2022 financial highlights, noting our detailed financials can be found in our 10-Q and press release, both of which were filed this afternoon. As a reminder, all comparisons discussed today are between the second quarter of fiscal 2022 and the second quarter of fiscal 2021, unless noted otherwise.

  • For the second quarter, we reported total revenues of $77.9 million, as compared to $70.5 million for the same period last year, an increase of $7.4 million or 10.4%, driven by international sales growth and continued strength in US private networks. Sequentially, revenue increased by $4.7 million or 6.4%. As Pete mentioned, our total revenue for the second quarter was the highest since our first quarter of fiscal 2016.

  • North America which comprised 66% of total revenue for the second quarter was $51.0 million, an increase of $1.9 million or 3.8% from the same period last year, driven primarily by our private networks business. International revenue was $26.8 million for the quarter, an increase of $5.4 million or 25.5% from the same period last year. We are again pleased that our backlog continues to remain above $200 million, even after recognizing our highest quarterly revenues in over 6 years because of our innovative and differentiated product portfolio.

  • Gross margins for the quarter were 36.2% and 36.3% on a GAAP and non-GAAP basis, as compared to 38.2% and 38.3% in the prior year. Gross margins remained under pressure from inflationary headwinds and expedite costs related to supply chain disruptions, but improved sequentially from Q1 by 60 basis points. This is consistent with our prior earnings commentary where we noted that price actions to offset inflation would gain momentum as the year progress.

  • Second quarter GAAP operating expenses were $19.9 million and second quarter non-GAAP operating expenses which exclude the impact of restructuring charges and share-based compensation were $19.2 million. GAAP and non-GAAP OpEx were 0.8 and $0.9 million higher than the prior year respectively. The increase was driven by higher R&D costs incurred to complete the design out of for both problematic vendors, as well as higher commissions in line with strong orders and sales.

  • Second quarter GAAP net income was $5.7 million compared to $6.6 million last year. The decline was wholly attributable to a $1.8 million higher GAAP tax provision in the current quarter, which were from the release of the US deferred tax asset valuation allowance as reported in our fiscal Q3 2021 results. As a reminder, the increase in tax provision year-over-year will not increase our cash taxes paid. The company has over $500 million of NOL that will continue to generate shareholder value via minimal cash tax payments for the foreseeable future.

  • Second quarter non-GAAP net income which excludes restructuring charges, share-based comp and noncash tax provision was $8.5 million compared to $8.4 million for the same period last year. Second quarter non-GAAP EPS came in at $0.71 per share compared to $0.74 per share for the same period last year. Adjusted EBITDA for the second quarter was $10.1 million, which was flat to the prior year.

  • Adjusted EBITDA margins were 13.1% for the quarter. Moving on to the balance sheet. Our cash and cash equivalents at the end of the second quarter were $42.3 million. We continue to have no debt. During Q2, we continued to increase investment in working capital to facilitate higher sales growth and protect ourselves from supply chain disruptions.

  • Our strong balance sheet permits us to amass component supply and invest in international growth projects. As a result, accounts receivable and unbilled receivables grew by $12.9 million in the quarter. Additionally, higher international growth typically has longer payment terms than North American customers. Inventories also grew by $2.5 million in the quarter as we added more supply chain buffer stock.

  • AR and inventory growth was only partially offset by current liabilities, which grew by $4.0 million in the quarter. As a result of these workload increases and $2 million of stock buybacks in the quarter, net cash decreased sequentially from the first quarter by $5.0 million and by $0.7 million from Q2 of the prior year. We expect this working capital dynamic to moderate in subsequent quarters, returning us to strong positive cash generation. Regardless, our balance sheet remains very solid, leaving us well positioned to execute our long-term plans.

  • With that, I will turn it back to Pete for some final comments. Pete?

  • Peter A. Smith - President, CEO & Director

  • Thanks, David. Just a few additional comments before opening up for Q&A. I'm extremely proud of the entire Aviat team for their significant contributions to our results for the second quarter of fiscal year 2022. We continue to execute well, given the constrained supply situation and inflationary environment. Despite these challenges based on our first half performance, we are raising our full-year guidance as follows. Revenue for fiscal year 2022 to be in the range of $290 million to $298 million and adjusted EBITDA to be in the range of $37 million to $39 million, providing our customers with the most advanced, reliable and best total cost of ownership systems for mission-critical work and our shareholders with profitable growth remains our goal.

  • With that, operator, open it up for questions.

  • Operator

  • (Operator Instructions) And our first question will come from Scott Searle with ROTH Capital.

  • Scott Wallace Searle - MD & Senior Research Analyst

  • Nice job on the quarter, very difficult operating environment. Hey, Maybe Pete...

  • Peter A. Smith - President, CEO & Director

  • Thanks, Scott.

  • Scott Wallace Searle - MD & Senior Research Analyst

  • Just to dive in quickly on the guidance for the fiscal year. It looks like it would probably imply that you're down a little bit sequentially into the March quarter, typical seasonality. Is that how we should be thinking of it above consensus expectations, but down a little bit sequentially from the December results?

  • Peter A. Smith - President, CEO & Director

  • Yes, so we've talked in the past about seasonality, some years there are seasonality and some not being a project-based business. And what drives the seasonality when we have it is year-end buying from principally from our government customers and we certainly had that this year.

  • Scott Wallace Searle - MD & Senior Research Analyst

  • Okay. And maybe to dive in on the software component. I think you indicated about a $300 billion TAM on that front. I wonder if you could expand on that a little bit in terms of software contribution maybe near-term and how you start to penetrate that opportunity?

  • Peter A. Smith - President, CEO & Director

  • Right. So that's around our routing, right, where we have high availability routing software for a state network and that project went well. We cited that there's a $300 million TAM. And what we'll be selling when we have those wins, we will have microwave radio router and the embedded software. And now that we've proven ourselves, our funnel is starting to grow. So that -- when we sell that embedded that routing software, that will be as embedded software.

  • With respect to our overall software, we're reluctant to break out the embedded software as a stand-alone because we can only sell it in conjunction with hardware. And then just to keep going on this, we do have our FAS, which is a stand-alone software, but it's not -- it's helped our margins and over the past couple of years, but it's not material enough to break out. Is that helpful?

  • Scott Wallace Searle - MD & Senior Research Analyst

  • Perfect. And maybe if I could jump in on the RDOF front. It sounds like some of these RDOF deployments are starting to get underway, I think to date, you've seen very little if any contribution. I think you articulated a $3 billion opportunity with existing customers. How do you expect that to flow in? And then if you could as well, the infrastructure bill seems like it's coming behind it, I feel there's some politics probably in terms of the allocations and time lines there. But there's been a big push in terms of American Made and you guys certainly fit that bill. So I guess, how does RDOF kind of flow into the current calendar year? And where do we start to see the benefits from the infrastructure bill starting to kick in?

  • Peter A. Smith - President, CEO & Director

  • Yes, so we think that we're not aware of any RDOF spending with Aviat yet. So it's all yet to come, so that's upside for the business. And our best estimate of when we can expect to see an RDOF impact is in the back half of this calendar year. So it's in front of us all of it. And then the building infrastructure fund or the policy wonks HR3684, the -- there's 4 steps for implementation. First, the FCC needs to update their maps and we think that's in the summertime of this calendar year.

  • Then the Commerce Department is creating a process for states to apply and that application from what's been published is May 2022, then the states will develop their plan for permission, I mean for submission and then they'll be reviewed and approved by the Commerce Department. And we think that, that's the end of '22, the beginning of 2023 for that funding to make an impact.

  • Scott Wallace Searle - MD & Senior Research Analyst

  • Great. Perfect. And lastly, if I could, International had a great quarter, you're up 25% year-over-year. It seems like looking at it geographically, Latin America and Middle East and Africa did well. Is that -- are you benefiting from Huawei tear-out or Huawei being less visible? And then on the European front, big opportunities there, I think in terms of what you're starting to win hasn't shown up in the numbers yet. When do we expect Europe to start to kick in?

  • Peter A. Smith - President, CEO & Director

  • So when we report our segments, Europe is up driven principally by the private network in the UK. And -- but secondly, we did have some good growth in the Europe region driven by Huawei share gain, that was the Southeastern Europe network operator. And then thirdly, on Africa, we are seeing some share gain from Huawei. And what we're finding is that the 5G -- a lot of our business in Africa this quarter was around 5G deployment, so getting the sites prepped and getting demos done. So we think that, that's going to bode well for the Africa region going forward. So, great, great question. Thanks, Scott.

  • Operator

  • Our next question will come from Dave King (sic) [Dave Kang] with B. Riley.

  • Ku Kang - Senior Research Analyst of Optical Components

  • I guess my first question is, I believe you said regarding the supply chain situation that it should start to ease post June. So how should we think about gross margin in calendar second half? Does it go back to like 38% or so. Can you just provide some more color what to expect?

  • David M. Gray - Senior VP & CFO

  • Hey, Dave. I would comment on that by saying, yes, we're still on track with what we said previously as far as our pricing actions being able to fully offset the cost increases that we've been seeing by our Q4 of this year. And looking out at that quarter and beyond, we still expect the overall inflationary impact to be somewhat dilutionary because even though our price actions will offset dollar-for-dollar, you're also increasing the denominator, while holding the numerator study.

  • So that will have some impact. But we do expect as the momentum continues to unfold here that it will -- we'll be able to hold on to those pricing gains and start seeing some better accretion on the gross margin line.

  • Peter A. Smith - President, CEO & Director

  • And Dave, to just to add on that, we're -- it will be a little while before we give guidance for fiscal year '23. And the other belt what we'll need to balance is how much traction we have on our software, on our innovative new products versus the international growth. So -- but Dave just said one important thing is that we still maintain that we're going to get back to parity from cost price in our April to June time frame and then the -- so then we're back to where we were before this environment took hold and then it will be -- our margin improvements will be predicated on mix and capturing more software and more innovation.

  • Ku Kang - Senior Research Analyst of Optical Components

  • Got it. And then my second question is on, you talked about having various trials, number of trials last year that you expect those will go into production district. Can you just provide us or give us an update or some data points exact how many trials you had? And how many you expected to go into production this year?

  • Peter A. Smith - President, CEO & Director

  • So well, I'm struggling with a little bit what I meant by the trials, but let me give you the one that I'm ready to prepare. We talked a lot about Multiband XD, our new product we have -- that's opened up another 50 million of TAM versus fiber. We're in 2 trials with lead customers on the high availability software. We've passed the FAT with a state network customer and we sold that to maybe a half dozen other customers.

  • And the pipeline on the high availability routing software, we have another 5 or 10 customers behind there. So when we think about our pipeline, we kind of parse it out by the innovative products. And I think to be as responsive as possible to your question, on the Multiband XD, we have 2. We have more customers on the high availability routing software and we have about a half a dozen that are queued up for trials.

  • Ku Kang - Senior Research Analyst of Optical Components

  • Got it. And my last question is on OpEx. It was up approximately $1 million sequentially to $30 million or excuse me, SG&A. How should we think about OpEx going forward?

  • David M. Gray - Senior VP & CFO

  • Well, I think it's safe to say that we believe that our Q2 was probably the high watermark for OpEx in this fiscal year. Some of those extra expenses that were noted in the earlier comments should not recur, so they should moderate somewhat in the back half. That will also be balanced against some modest seasonality that typically exists in our OpEx, but it should be fall back a little bit and be more in line with what we've seen in previous years.

  • Operator

  • And our next question will come from Tim Savageaux with Northland Capital Markets.

  • Timothy Paul Savageaux - MD & Senior Research Analyst

  • Hey, how's it going. Just trying to think about how to frame this question, I guess I'll start kind of with the gross margin approach and mix US versus international is typically an important factor. And so I want to think about that both short-term and long-term. In the quarter you just reported, I think you were able to increase gross margins, what you said 60 bps despite a much higher international mix. So I guess, start question one, how did you do that? And David, I wonder if you can specifically frame the supply impact on that, whether that's a couple of hundred basis points or what have you. And then longer-term, lot of what you're talking about opportunity-wise appears pretty US focused, right, RDOF, DISH, other state level. And so should we think about that US mix increasing and bringing gross margins up with it? Or are there other dynamics at play here as we go through the rest of the year?

  • David M. Gray - Senior VP & CFO

  • Okay. I'll speak to the gross margin first and then Pete can talk to the international versus domestic mix. So for the quarter, the cost increases impacted our margins by roughly 340 basis points negatively. That was offset partially by our price recovery actions that added about 230 basis points. That's about 2x what we reported in our first quarter.

  • And then you're right, the international strength did have a bit of a dilutive effect by about 80 basis points to 90 basis points in the quarter. So that kind of is a walk year-over-year from a margin perspective. And then we, again, continue to expect the pricing actions to gain traction in the future quarters to help offset those inflationary pressures that we've seen.

  • Peter A. Smith - President, CEO & Director

  • So Tim, on the mix, right? We've said that our long-term target gross margin is 40% and the way we were planning on getting there was through hardware innovation and software. And as we've done traction with the international team, we think that there's a good growth opportunity there that we're digging into, but we have our first proof point.

  • I think your question is when RDOF kicks in and the infrastructure fund kicks in, will that drive more growth in the US side? Yes, that is more margin accretive. So one of the -- I gave my best estimates on when that funding will hit. And we want to keep our regional mix model the same, 2/3 North America, 1/3 the rest of the world. And we will revisit that as that funding starts to flow, but there's no denying that when it does, it will be margin accretive for us. I think -- Dave, are you still there?

  • Timothy Paul Savageaux - MD & Senior Research Analyst

  • Sorry. I'm on mute.

  • Operator

  • Sorry, go ahead.

  • Timothy Paul Savageaux - MD & Senior Research Analyst

  • It was a really interesting question too, too bad. To stick with RDOF and so you mentioned you had won awards, I think backed by 3 bid with -- carriers are backed by $3 billion in awards. And historically, I want to ask about you had a onetime estimated kind of a TAM range for Aviat in the 2% to 4% range based on that network build cost or maybe even based on those awards. As you have more experience with these deals and are winning a lot of them, is that still a reasonable range, any bias toward the high and low end or kind of any update in general on how you see your market opportunity out of those award funds or work builds?

  • Peter A. Smith - President, CEO & Director

  • Yes, I would say we're the same, right? So the reason we put the $3 billion number in last time was -- you asked a question that we didn't have last time was of your winners how much does it represent an opportunity of $3 billion. We would stick with the 2% to 4% of the funding goes to microwave. And in our investor presentation, we think that we have 38% share. And I wouldn't say that any of that's materially changed. So as you kind of model our potential upside when the RDOF funding, I would say that the numbers are the same.

  • Timothy Paul Savageaux - MD & Senior Research Analyst

  • Great. And that $3 billion number is pretty much the total amount of awards to fixed wireless carriers? Is that co-incidental or are there any -- is there anything outstanding there or you kind of won them all?

  • Peter A. Smith - President, CEO & Director

  • Let me check if that's a coincidence or a fact, I didn't do that totally, but we'll get back to you on that, but it's -- we got to be pretty close to winning them all.

  • Timothy Paul Savageaux - MD & Senior Research Analyst

  • Yes, well, I'm just saying your share sounds anecdotally higher than 38%, but it really hasn't started to roll yet. And I figured there was limited impact looking at the flat sequential US numbers from RDOF. As you look at the state level, I don't know if you're seeing any funding or opportunities not for state networks but coming out of state level funding. And I'd ask you the same question on DISH in terms of -- it doesn't seem like that started to be material yet. What's your expected timing on that?

  • Peter A. Smith - President, CEO & Director

  • Yes, I think the state funding environment is pretty stable and the positive catalyst is the infrastructure fund. And then there's one bit of legislation that I don't know that we fully understand what the conversion of the leftover cares money, that could be a positive catalyst, but we don't know specifically about that. And then on DISH, it hasn't been material, but we're seeing signs that it will have some positive impact, let's say, in Q4 of our fiscal year.

  • Operator

  • And our next question will come from Theodore O'Neill with Litchfield Hills Research.

  • Theodore Rudd O'Neill - CEO & Research Analyst

  • Yes, congratulations on the quarter.

  • Peter A. Smith - President, CEO & Director

  • Thanks.

  • Theodore Rudd O'Neill - CEO & Research Analyst

  • A couple of questions for you. Could you -- could sales have been higher if you had had supply chain issues in the quarter? And do those -- and if they could have been, do those sort of come later? Or do they use just get taken up when consumed by competitors?

  • Peter A. Smith - President, CEO & Director

  • Well, Theo, I'm pleased to report that we didn't miss any demand due to supply chain issues in the quarter. And if you go back the past couple of quarters, we said we missed $1 million or $2 million, but our supply chain team performed well and we didn't miss any demand. And I think that's the first time that that's been the case in 3 or 4 or maybe more quarters. So that's another sign that the environment is stabilizing and I'll keep my fingers crossed that maybe the supply environment is moderating.

  • Theodore Rudd O'Neill - CEO & Research Analyst

  • That's terrific. And Pete, on the last quarter, you said that you're now supplying 15 of the top 30 rural digital opportunity fund winners and are in advanced discussions with 5 of the other -- of the top 30. How is that going?

  • Peter A. Smith - President, CEO & Director

  • Yes, I would say we've gotten one out of the 5. So we're -- let's go for 16 of the top 30.

  • Theodore Rudd O'Neill - CEO & Research Analyst

  • Great. And your -- it was noted earlier, with your sales in the Africa and Middle East segment were up 30% sequentially and they've been I think they've been flat for many quarters. As we sort of model out these -- our own projections, should we consider that sort of be stable at this new level? Or how should we think about that?

  • Peter A. Smith - President, CEO & Director

  • So we think that -- look, it was an exceptional quarter Q2 -- and we -- and if we want to kind of do that, our North America business was not growing as much and international was growing more. And we would say that the way to get -- look at our revised revenue guidance and just used the 2/3 North America, 1/3 split. So I think that's about the color we can give. And -- but I would say on the Africa side, as those -- the 5G prep work is completed, then you could imagine later this calendar year this having a positive impact. But to hedge back on that a little bit, we're still -- we still see the 2/3 North America 1/3 and we want them both to grow -- to grow. So that's where we're at. It's a good question.

  • Operator

  • (Operator Instructions) And our next question will come from Aaron Martin with AIGH Investment Partners.

  • Aaron Martin - Strategic Advisor

  • How are you, guys? Congratulations on nice quarter and appreciate the continued execution on the buyback. Going back to the AR, was that increase there related to the shift in revenue international, anything related to there? Or what else -- because it's been a nice little rebound.

  • David M. Gray - Senior VP & CFO

  • Yes, this quarter, it was almost entirely due to international growth. If I look at the regional breakout of our AR and so that was definitely a driving factor, which we typically have longer payment terms with international customers in addition to the strong growth. So those were the 2 biggest contributing factors that's -- again we expect that to start to come back in subsequent quarters.

  • Aaron Martin - Strategic Advisor

  • And then as I -- I think you talked about the backlog still being over $200 million, was it up sequentially?

  • Peter A. Smith - President, CEO & Director

  • So we don't break out backlog on a quarterly basis because of the project nature. The other thing we would add to give you a little more insight is, our book-to-bill ratio remains above 1.

  • Aaron Martin - Strategic Advisor

  • Okay. And then as I look at that on the higher backlog, is any of that a function of longer lead time and your customers having to order ahead for a little longer? Or is that really emblematic of true demand?

  • Peter A. Smith - President, CEO & Director

  • So we -- our private network business is long cycle. So we don't see very much acceleration of demand in that segment. And we certainly haven't seen the mobile network operator space. So we -- if that's going on, we're not aware of it. So I wouldn't say we have any acceleration of demand. So it's really true demand.

  • Aaron Martin - Strategic Advisor

  • Got it. And as I think about growth over the next 6, 12, 24 months, what's a more important driving factor? Is it rural broadband? Is it 5G rollouts really happening? What are the bigger factors in terms of whether the growth will show up and how strong it will be for you guys over that time frame?

  • Peter A. Smith - President, CEO & Director

  • Yes, so we have 3 drivers that we talk about private networks, which is about 2/3 of our business. So that's really important. And I think that's not going to be a steady grower for us. And when the BIF, the infrastructure fund kicks in, that should be a growth accelerant. The rural broadband is really -- would be a growth accelerant and 5G, we think we're in the early innings. We are really happy to see the developments particularly in Africa and that would be a growth accelerant.

  • So if you look at the -- in terms of the core company, the private networks is most important, but in terms of accelerating growth, the 5G and the rural broadband should be pleasant developments for us, say, one to 2 years out.

  • Aaron Martin - Strategic Advisor

  • Got it. And then you talked about a multiband how customers are very excited at the release. And I think you said it enables a $300 million TAM in space for you. Can you talk a little bit about your initial, I guess, test I don't know if you've taken any orders yet with -- particularly for multiband and any quantification around the initial rollout of that product?

  • Peter A. Smith - President, CEO & Director

  • Yes, so the $300 million TAM expansion was with our high availability routing software. So the Multiband XD makes our microwave radio's more competitive versus fiber. And we think at that distance, we have -- we've opened up $50 million more of TAM. So that would be share gain versus fiber. And we are in trials with 2 lead customers and where these lead customers are is when -- where they're using fiber and the total cost of ownership with the fiber increases dramatically with link distances. So think about mountainous terrains or kind of island-based nations where there's a lot of water. Do we think that this is -- improves the value proposition for microwave and we're really excited that we have 2 significant customers that are in trials.

  • Aaron Martin - Strategic Advisor

  • Okay. And then on the new 10-gig very long-distance radio, where are you with that of the customers? Do they care about the additional capabilities and/or catching up? Or what can you tell me there in terms of acceptance?

  • Peter A. Smith - President, CEO & Director

  • All right. So the -- yes, 10-gig radio and a Multiband XD are the same. So the commentary -- that commentary is related to the Multiband XD radio.
