Ladies and gentlemen, thank you for standing by, and welcome to the Q1 2021 Harmonic Earnings Conference Call. At this time, all participants are in listen-only mode. After the speakers' presentation, there will be a question-and-answer session. [Operator Instructions] Please be advised that today's conference is being recorded. [Operator Instructions] I would now like to hand the conference over to your speaker today, Mr. David Hanover. Please go ahead sir.
Thank you, Operator. Hello, everyone, and thank you for joining us today for Harmonic's first quarter 2021 financial results conference call. With me are Patrick Harshman, President and Chief Executive Officer; and Sanjay Kalra, Chief Financial Officer.
Before we begin, I'd like to point out that in addition to our audio portion of the webcast, we've also provided slides for this webcast, which you may see by going to our webcast on our Investor Relations website.
Now turning to Slide 2.
During this call, we will provide projections and other forward-looking statements regarding future events or future financial performance of the Company. Such statements are only current expectations and actual events or results may differ materially. We refer you to documents Harmonic filed with the SEC, including our most recent 10-Q and 10-K reports and the forward-looking statements section of today's preliminary results press release. These documents identify important risk factors which can cause actual results to differ materially from those contained in our projections or forward-looking statements. And please note that unless otherwise indicated, the financial metrics we provide you on this call are determined on a non-GAAP basis. These metrics, together with corresponding GAAP numbers and a reconciliation to GAAP, are contained in today's press release, which we posted on our website and filed with the SEC on Form 8-K.
We will also discuss historical, financial and other statistical information regarding our business and operation, and some of this information is included in this press release. The remainder of the information will be available on a recorded version of this call or on our website. And now I'll turn the call over to our CEO, Patrick Harshman. Patrick?
Thanks, David, and welcome everyone to our first quarter call. Harmonic delivered another solid quarter with seasonally strong new bookings and solid year-over-year revenue earnings and cash growth. In both our cable access and video segments again contributed meaningfully and both carry substantial backlog and deferred revenue into the remainder of the year.
For cable access the story is continuing to scaling by existing customers and new customer wins, driving 79% year-over-year segments revenue growth.
For video business demand for both our broadcast and streaming solutions remained healthy, enabling us to deliver 29% year-over-year segment revenue growth. Big picture Harmonic continues to respond well to both current challenges and opportunities, leveraging and continuing to invest in differentiated technologies, deep customer relationships and an extraordinary global team.
All of this translates into strong market momentum in an increasing growth outlook for the remainder of the year.
So focusing first on our cable access segment, we delivered another strong quarter. We were commercially deployed with 53 cable operators worldwide, up 96% from the first quarter of 2020. And these deployments scaled to serve over 3 million cable modems up 127% year-over-year. Segment revenue was $41.3 million up 72% from a year ago and the margin sagged somewhat as we had a heavier mix of DAA hardware in the quarter and our hardware was impacted by higher costs, we nonetheless again delivered positive segment operating margin.
Looking ahead, we're well positioned to continue this pace of revenue growth. We see broad market momentum for next generation multi gigabit broadband solutions spanning fiber cable and wireless and the emergence of cloud native software working in concert with an open distributed access architecture as the winning formula. Within cable Harmonics cloud native and DAA solutions continue to be way out in front of the rest of the market. It's gratifying to have been recently recognized for the Dell'Oro Group as the market leader in these next generation technologies. To fully leverage our unique position, we're focused on three interrelated growth vectors, working with existing customers to scale CableOS deployment across their entire footprints, winning new customers from large tier ones to rural broadband players, and expanding our address market to include fiber to the home and fiber to the business. We're so good progress in all three of these initiatives during the first quarter.
Regarding customers we're already actively deploying CableOS, deployments are going really well. The pace is accelerating and the other solution has been rolled out to less than 6% of their combined footprints which means we still have huge growth one way ahead of us with these already deploying customers.
Regarding adding new customers, we also continue to make good progress. We received an initial multimillion dollar purchase order from the new tier one international operator, and we went several new regional and rural North America broadband customers during the quarter. And regarding fiber to the home, we closed our first deal in North America. And I've seen steady growth in our global sales pipeline with engagement spanning a diverse group of larger cable operators and smaller rural broadband players. Underlying all this activity, we continue to invest heavily in new technology and services. And based on insights from our ongoing deployments, we are adding compelling new functionality to our cloud native software core -- support for new applications such as mobile backhaul and we're engaged in innovative joint efforts with public cloud players around new edge cloud capabilities. And, of course, our converged cable for fiber to the home solution continues to be a key R&D initiative.
Finally, we're not immune to the global supply chain constraints. We're seeing shortages of several key components and related significantly higher costs, impacting more significantly our DAA and shelf hardware products. We're working hard to overcome these challenges. And as a result, while we expect higher costs and lower margins for these products for the balance of 2021, we're not backing off of our revenue growth target. We're aggressively seizing new opportunities to expand our DAA footprint and correspondingly raising our top line guidance. And summarizing for cable access, Harmonic delivered another strong quarter. Global broadband market trends are favorable, near term demand is healthy.
Our early customers are successfully scaling and we continue to add new customers both large and small. The future broadband access technology is clearly cloud native core software powering the flexible distributed access network. And as a primary architect to this new model Harmonic's broadband access future remains bright. Returning to our video segment, we followed up a strong second half of 2020 with another solid quarter.
First quarter segment revenue was $70.3 million, 29% year-over-year, and up 5% from the first quarter of 2019 indicating growth is more than just post pandemic recovery. Gross margin was 55.1% and segment operating margin was 5.4% impressively demonstrating continued profitability despite business transformation headwinds.
As you know our key strategic transformation is from a purely broadcast technology and associated CapEx business model, the mix of broadcast CapEx and streaming SaaS with recurring revenue. Demand for high quality live streaming solutions continues to grow evidenced by a strong sales pipeline, several new streaming SaaS wins and our near record backlog and deferred revenue.
During the quarter, we signed net seven new streaming SaaS customers, mostly customers that are new to harmonic, bringing the total number of media companies on our streaming platform to 97, which is up 72% year-over-year. Approximately a quarter of these customers are still in the process of fully launching their new streaming services underlying our continued streaming growth expectations.
As a recent example, a prominent new sports streaming service that we signed in 2021, on lag with us just a couple of weeks ago and is already delivering millions of daily ad impressions, with even higher ad volumes anticipated as the service expands.
So the ad insertion portion of our SaaS solution is charged on impression volume or CPM. The associated growth opportunity for this part of our video business is becoming more compelling.
While streaming is the main headline, our secondary headline is revitalized broadcast demand. We're seeing a general rebound in broadcast project activity worldwide, which we believe we're capturing an increasing share. We're also seeing 5G bandwidth reclamation, continuing to be a catalyst for both near term business and longer term opportunity creation globally.
During the first quarter, we continued to execute our announced program with SES and several new 5G bandwidth reclamation projects came into focus, new projects that we now expect to contribute to the second half of the year in 2022.
We are correspondingly raising our video segment revenue guidance mostly for the full year.
Looking further ahead, we believe that success the industry is seeing with the C-band initiative is opening the door to a broader opportunity for wholesale IP video distribution by a terrestrial fiber rather than satellite networks, a positive trend for sustained video broadcast investment.
So in summary, we delivered another strong video quarter characterized by solid revenue growth, gross margin, operating profit, new wins and bookings. This performance highlights the resilience of our video business, our industry leading technology and the growing success extending our brand from the realm of high end broadcast to high performance cloud streaming and SaaS. Leveraging our strong backlog and deferred revenue and robust video sales pipeline, moving forward through 2021 with real market momentum and conviction integrated wealth plan.
So let me now turn the call over to you Sanjay for a closer look at our financial results and outlook.
Thanks, Patrick, and thank you all for joining us today.
Before I discuss our quarterly results and outlook, I like to remind everyone that the financial results, I will be referring to are provided on a non-GAAP basis.
As David mentioned earlier our Q1 press release an earnings presentation includes reconciliations of the non-GAAP financial measures to GAAP that are discussed on this call.
For the first quarter of 2021, we delivered solid results generally above our guidance ranges. We reported Q1 revenue of 111.6 million, up 42.3% year-over-year and gross margin of 50.4% or 150 basis point improvement year-over-year. Operating margin was 4.5% comprised of 3.1% for cable access and 5.4% for video and we generated adjusted EBITDA of $9.1 million and EPS of $0.04.
We also had seasonally strong bookings during the quarter with a book-to-bill ratio of 0.9.
As a result, we ended Q1 with a solid backlog in deferred revenue of 274.3 million positioning as well for the remainder of the year.
Now I will review our first quarter financials in more detail.
Turning to Slide seven, total company Q1 revenue was 111.6 million or 42.3% increase compared to 78.4 million in Q1 '20.
As Patrick mentioned, we continue to see increased traction in our cable access business. And in Q1 with 53 commercial deployments, which is sequential growth of 20% compared to 44 at December 31, and up 96% year-over-year. Cable access revenue was 41.3 million up 72.1% compared to 24 million in Q1 2020. In our video segment, we reported Q1 revenue of 70.3 million up to 29.2% compared to 54.4 million in the prior year period.
We continue to see recovering video activity worldwide during the quarter, including continuous satellite C-band 5G related revenue. We had two customers representing greater than 10% of total revenue during the quarter. Comcast contributed 23% of total revenue and SES contributed 16%.
As mentioned earlier, gross margin improved to 50.4% in Q1 '21 compared to 48.9% in Q1 '20 up 150 basis points. Cable access gross margin declined slightly to 42.2% in Q1 '21 compared to 43.3% in Q1 '20 down 110 basis points, reflecting increased supply chain costs and a higher mix of DAA hardware.
As previously mentioned, cable access operating margin was 3.1%. Video segment gross margin was 55.1% in Q1 compared to 51.3% in Q1 of last year, a 380 basis point recovery to business as usual before the pandemic.
Moving down the income statement on Slide eight, Q1 '21 operating expenses are 51.1 million compared to 47.9 million in Q1 '20. The year-over-year increase was primarily due to increased cable access research and development and services and sales and marketing for both segments as we continue to invest in our growth initiatives.
The secondary reason for the increase was the conversion of some employee incentive compensation from stock to cash.
As I will explain further when I discuss our guidance. We reported operating profit for the first quarter of $5.1 million comprised of 1.3 million from cable access and 3.8 million from video. This is a substantial year-over-year improvement compared to an operating loss of 9.5 million in Q1 '20. Adjusted EBITDA for the first quarter was 9.1 million reflecting contributions of 3 million from cable access and 6.1 million from video. This compares to an adjusted EBITDA loss of 7 million in Q1 '20 and translates to Q1 EPS of $0.04 compared to Q1 '20 EPS loss of $0.10. We ended the quarter with a diluted weighted average count of 103.2 million for shares compared to 100.3 million in Q4 '20. The situation increase is primarily due to the issuance of 2 million shares to employees for vested restricted stock units [indiscernible] purchases and performance based compensation and 0.9 million shares for convertible debt valuation as a result of our increased average stock price. Q1 bookings were 96.3 million or 26.2% increase compared to 76.3 million in Q1 '20. It was encouraging to see another quarter of year-over-year bookings growth during the first quarter, demonstrating continued strong demand for our differentiated technology solutions.
Turning to Slide nine, we now discuss our liquidity position and balance sheet. We ended Q1 with cash of 100.8 million compared to 71.7 million at the end of Q1 '20 and 98.6 million at December 31. The 2.2 million sequential cash increase is comprised of 1.7 million cash generated from operations primarily attributable to the profitability in both our businesses. Net of 3.6 million cash using the purchase of fixed assets and 4.7 million received from common stock sold to employees under our ESPP and from stock option exercises.
Our days sales outstanding at the end of Q1 was 69 days compared to 107 days in Q1 2020. The year-over-year decrease in DSO reflects continued overall collection improvements and the timing difference of certain large receivables.
Our days inventory on hand were 58 days at the end of Q1 compared to 78 days at the end of Q1 2020. At the end of Q1, our total backlog and deferred revenue was 274.3 million, compared to 207.9 million at the end of Q1 2020 and a record 290.5 million at the end of Q4 '20, reflecting a sequential decrease of 6%.
Our near record backlog and deferred revenue reflects both increasing commitments for our large cable customers and our growing video streaming SaaS businesses.
We are pleased to be maintaining a strong level of high quality backlog know that historically about 80% to 90% of our backlog and deferred revenue gets converted to revenue within a rolling one year period. Also, the deferred revenue component of our total backlog in deferred revenue was 27% at the end of Q1 compared to 27% at the end of Q1 2020, demonstrating that revenue conversion of backlog and deferred revenue continues at levels consistent with our expectations.
As mentioned on previous calls, not included in our backlog is additional contractually agreed CableOS business with three of our tier one cable customers. At the end of Q1 '21, this incremental amount was approximately 156 million down from 158 million last quarter, as approximately 2 million went through the purchase order process and therefore moved into bookings. Taking these CableOS contracts into account, we have total future contracted revenues of 430.3 million, which provides us with a solid foundation for the remainder of 2021 and into 2022.
Now I will turn to our non-GAAP guidance for 2021 on Slide ten.
While COVID-19 related uncertainty and volatility still exists, our customer activity and pipeline have substantially recovered since the height of the pandemic.
On the other hand, we are contending with a somewhat unprecedented global supply chain situation, creating both cost and production timing challenges. Based on extensive conversations with our key customers and supply chain partners and internal analysis, we expect that demand recovery will continue throughout the balance of 2021. With over typically seasonally, stronger Q4 and second half and that meeting this demand will likely be somewhat at higher cost, particularly for our cable access hardware products.
For the full year of 2021, we expect total company net revenue in the range of 435 million to 480 million, at the high-end, this reflects upwardly revised growth expectations for both segments. Gross margin in the range of 50.6% to 52% at the midpoint of our guidance, this represents a decline of 120 basis points year-over-year. This reflects a slight increase in video gross margins and a lower gross margin on cable, which I will elaborate on shortly. Operating expenses range from 209 million to 218 million, an increase from previous annual guidance due to increased cable access to research and development expenses and the decision to settle certain employee incentive compensation payouts with cash instead of stock reducing valuations. The latter was a decision recently made with our board considering our stronger cash position and operating plan. Adjusted EBITDA to range from 25.1 million to 45.7 million, an increase of approximately 49% year-over-year at mid-point. EPS will range from $0.06 to $0.24, an effective tax rate of 10%, our weighted average diluted share count of approximately 104.7 million. And finally cash at the end of the year is expected to come in between 110 million to 120 million. On Slide 11, I will focus on total company guidance for the second quarter. Revenue in the range of 102 million to 112 million at the midpoint of our guidance this reflects an increase of 45% compared to Q2 last year. Gross margin in the range of 48.7% to 50.6% at midpoint of our guidance, this reflects a decline of 195 basis points compared to Q2 last year. Operating expenses to range from 52 million to 54 million, due to the reasons mentioned previously. Adjusted EBITDA to range from 0.8 million to 5.8 million, versus a loss of 2.8 million in Q2 last year. EPS to range from a loss of $0.03 to a profit of $0.01 per share and effective tax rate of 10% of weighted average diluted share count of approximately 101.2 to 104.2 million. And finally, cash at the end of Q2 is expected to range from 90 million to 100 million. Starting this fiscal year, we will be augmenting our segment guidance to include segment gross margin, operating expense and adjusted EBITDA corresponding to our existing practice of providing these segment metrics in our reported quarterly results. On Slide 12, I will discuss guidance for over video segments for the full year and the second quarter.
For the full year 2021, we expect video revenue in the range of 260 million to 280 million. At the midpoint of our guidance, this reflects 11% growth year-over-year attributable to both rebounding broadcast market demand and growth in streaming. Gross margins in the range of 55% to 57%. At the midpoint of our guidance, this represents 150 basis point improvement over last year, mainly due to improved product mix. Operating expenses are expected to be between 138 million to 143 million, an increase of 7% versus last year. Most of the increase is due to increased sales expenses tied to over higher projected revenue. Adjusted EBITDA in the range of 13.5 million to 25.1 million, an increase of 135% over last year at the midpoint.
For Q2, we expect video revenue in the range of 57 million to 62 million. at the midpoint of our guidance this represents approximately 25% growth over Q2 last year.
We expect video gross margin in the range of 54% to 56%. This year, the midpoint is at 20 basis point improvement from Q2 last year. Operating expenses to range from 34 million to 35 million, an increase of 14% over Q2 last year due primarily to increased sales expenses as mentioned previously. Adjusted EBITDA to range from a negative 1.3 million to a positive 1.6 million. On Slide 13, I will give you guidance for our cable segment for full year and the second quarter.
For the full year 2021, we currently expect cable access revenue in the range of 175 million to 200 million. At the midpoint of our guidance, this reflects a 38% growth year-over-year. This growth is driven by strong momentum with our existing customers as the actual rate deployment as well as new customer growth and models converged fiber to the home revenue. Gross margins in the range of 44% to 45%, a 440 basis point decline versus last year at the midpoint, due primarily to increased costs related to supply chain headwind and an increased mix of DAA hardware. Operating expenses are expected to be between 71 million to 75 million, an increase of 33% versus last year. Most of the increase is due to increased research and development and sales and marketing expenses. Adjusted EBITDA in the range of 11.6 million to 20.6 million, an increase of 3% over last year at the midpoint.
For Q2, we currently expect cable access revenue in the range of 45 million to 50 million. At the midpoint of our guidance, this reflects 79% growth for cable over Q2 last year. Gross margin in the range of 42% to 44%, at midpoint of our guidance this reflects a 270 basis point reduction over Q2 last year.
For the reasons mentioned previously, for the full year gross margin guidance. Operating expenses to range from 18 million to 19 million, at the midpoint of our guidance, this reflects a 42% increase over Q2 last year, primarily due to increased research and development and sales and marketing expenses. Adjusted EBITDA to range from 2.1 million to 4.2 million. In closing, again, we are grateful for our team's continued dedication and strong performance during the first quarter.
We continue to execute on our strategic priorities, positioning our cable access and video streaming businesses for long-term success. With that, thank you, everyone. And now I'll turn it back to Patrick for final remarks before we open up the call for questions.
Okay, thanks, Sanjay. We want to conclude by reviewing our strategic priorities for the year.
For our cable access business, our objectives are accelerated expansion of existing tier one deployments, entering new global operators, particularly additional tier ones, and expanding our domestic market for CableOS new converged to DOCSIS, the fiber to the premises capabilities.
We are pushing forward aggressively despite near term cost challenges.
For video segment, our objectives are accelerating the growth of our streaming and SaaS customer base and usage, capitalizing on the coming transformation of traditional media and broadcast infrastructure globally and delivering both top and bottom-line growth, putting it all together, we aim to create value to deliver industry leading solutions and to enable superior subscriber experiences worldwide. And finally, we're pleased to announce that later in May, we will be hosting two special industrial events, a deep dive into our cable access business and associated multi-year outlook and a similar deep dive in multi-year outlook for our video business, while featuring additional members of our executive management team.
We expect today's to be finalized shortly and hope that you all join us. With that I would now like to open up the call for questions.
[Operator Instructions] And your first question comes from Samik Chatterjee from JPMorgan.
Hi, this is Joe Cardoso on for Samik Chatterjee. My first question on your guide and kind of more of a clarification, you always obviously spent a large portion on the prepared remarks mentioning the supply constraints and implications on the higher costs. I'm just curious if you guys are seeing any implications on the supply constraints on your top-line? And basically, are you being impacted by your ability to supply customers? And whether you're making any of that into your full year guide?
Yes, in terms of top-line and the supply chain, we have factored in any risk we consider in our guidance range.
So our guidance [indiscernible] completely entails the risk we consider at this point for this supply chain.
I guess if I could just follow up there. Are you seeing any implications on your ability to supply customers currently, or is that not -- you have not done yet today?
We've not dealt with what to-date. If I can step in, we've not dealt with that to-date.
I think the current situation creates a ceiling, does not to say we're not working to remove that but it does create a little bit of a ceiling on the upside What we're talking about today is, is going beyond our guidance of last -- that we gave last quarter.
So we're fortunate that we don't see any reduced expectations. But if your question is, is sky the limit? Right now the sky is not the limit. And there is a scenario where demand may outstrip supply. But right now, the supply that we see, we think we can manage and actually manage to deliver a little bit of upside, albeit, as we've said, a couple of times, at higher than originally anticipated costs, simply entailed with getting that done. It's a dynamic situation.
As Sanjay said, we're confident that we've got the resources to deliver it within the range that we've talked about is upside on that possible, it is possible.
I think it's probably more likely that the demand is there, then that we'll be able to satisfy the demand. But both of those things are a little bit dynamic. And we'll continue to keep you updated as we move through the year.
I really appreciate the color. And then I guess, just for my second question, and this is more broader, it looks like there's a bunch of initiatives from governments globally in the pipeline, including RDOF and the infrastructure plan in the U.S. There's the U.K. project gigabit and the European Commission's broadband project.
Just curious to hear you know, your overall thoughts on these government projects in terms of when do you expect them to materialize? And how is Harmonic position to benefit from these investments globally? Thank you.
Yes. Well, I very much appreciate the question as your questions implied it's -- the world is a big place. And there's a lot of different initiatives with different timing happening all over the place. But I think we can agree the headline is, is that broadband and access to broadband is it's, it's a priority issue from every country from the United States to the U.K. to Bhutan, right? And so being a participant and being a key supplier of broadband enabled technology is a great place to be, we think we have an extremely strong position within cable. And as you know, we're working to expand that position to also address fiber.
Our first protocol, if you will, is those cable operators who are expanding in a fiber or have hybrid cable and fiber infrastructures. We think that that opportunity substantially expands our addressed market. And as we've discussed before, once we've kind of got that in play? Well, we think we can expand beyond that.
So we think it's a very attractive environment, we think we're well positioned. We're not targeting the totality of the market today. But we're targeting a growing subset of the broadband market where we can not only participate, but we're really, really can differentiate ourselves.
So we think that the future is pretty, pretty exciting. And it's one of the reasons why we're leaning in now. And we're continuing to lean in into investing in and both the current and our upcoming technologies to strengthen our position, not just for 2021 but for the next several years. And I guess just one last thing.
As I mentioned a moment ago, we do plan an investor event to really go into this topic from both the market and the technology perspective in more detail later on in the month. And I think that your question really hits on one of the reasons we want to have a slightly more in depth conversation to talk about what we're doing and the market opportunity that we see.
Thank you. Appreciate the question and congrats on the results.
And your next question comes from Tim Long from Barclays.
Two questions, if I could.
First on the C-band side.
Sounds like it's starting to broaden out a little bit more from a customer base.
So could you kind of just give us an overview, Patrick on kind of level of activity there and maybe update us as this moves along, any changes to the competitive environment? And then, on the cable side sounds like they are a really big pipeline outside of the backlog.
So maybe if you could kind of give us a sense as to why you're seeing that growth. Is it a lot of new deployment, is it the traffic growth what driving that or competitive wins and maybe a little bit on the slope of the curve to turn that stuff into revenues. Thank you.
Okay. Thanks for the question.
On the C-band stuff, indeed, we're seeing more opportunities. In particular, we see a couple of substantial new opportunities that really come into focus and where we see that is beginning to materialize in the second half of the year. And we also see it as high probability for 2022.
So I would say that there was that next wave of opportunity is domestic.
And so beyond that, we still see and we're engaged in a number of conversations around related international opportunities, but I would call those still is not quite in focus. And therefore not yet factored into in any way into the guidance that we've given. But from a broader trend, I think that it continues to be promising from our perspective, not only because the government is looking to recover bandwidth, but because the market is waking up to the fact that actually, there's a lot of benefits to moving video traffic over terrestrial fiber network personalization, customization, targeted ads, et cetera.
So it's a dynamic in a positive way, it's a dynamic, evolving opportunity that is leading to broader conversations with a number of customers, both domestically and internationally. There's not really been any change. The last part of that question, Tim is not really any change to the competitive environment. We're certainly not the only one. We've seen some deals go to what the competitors, but we think we're pretty uniquely positioned and we're really leaned into a couple of very significant additional opportunities.
On the cable front, look at since a little bit all the above in your comments, I think that as we touched on, the last question broadband is a must do whether it's from a consumer perspective, or from a government perspective, it's only becoming more important.
I think we all see that.
And so there's consumer demand, I think there's strong and we're seeing strong demand from both our existing customers to go faster. And from new customers and particularly our new customers as we continue to get success in the market with appointments, there's a virtuous circle, we think we're getting more and more credibility, perhaps slightly more conservative operators, or once we had a little bit more questions about the technology, they're getting more and more comfortable with the deployment volume, the success of the quality of service that we're seeing.
And so I think both of those things are factoring into a -- to strengthen the pipeline. That being said, the risk of rambling on here, we've also learned that depending on the environment, this is not necessarily a snap the thing go and deploy it overnight. There is a process and to the comments, here we're carefully managing our supply chain. And that also modestly impacts, I would say, the pace of which we can move.
So strong demand, competitive position is, I would say a stronger than ever. And I'd say the transition translation of all that into volume deployment is okay, it's not quite as fast as we'd like to see. Supply Chain inhibits that a little bit. But it's going okay. And I think if you look at our guidance range, the top end where year-over-year, it's a respectable number, getting close to 50%. And given everything that's going on in the market and the fact that we're still in many places, dealing with some pandemic related issues, etc.
I think that growth and our view that we want to discuss with you all later on the month of multi-year growth, all of that, from our perspective is quite positive.
And your next question comes from Simon Leopold from Raymond James.
I wanted to ask maybe if you could help folks, understand the metric you've been offering on the past several calls regarding the cable modem served, I guess, this quarter, you're up to 3 million. And you talked about 6% or better than 6%, which would imply that the customers have a total of about 50 million. Could you help us understand how you measure that metric and what stands between basically serving 3 million and 50 million is there? What needs to happen for that number to grow is really what I'm looking forward.
Okay, indeed, you've got it in round numbers.
You've got it about right. The people who are actively deploying CableOS today They serve about over 50 million cable modem subscribers. They are -- I don't know, right technology assignment now, they're kind of rebuilding the house, if you will, or repainting the house, so room by room. And it isn't the flip of the switch kind of thing. There is at a minimum in centralized architecture, so there is rewiring and we architecting of the main head end. And the DAA is used, actually there is deployment of DAA notes out in the neighborhoods, which means a truck needs to roll, someone needs to go up in a bucket truck or go down to the ground and replace an old node with an existing node. And very often that involves pulling fiber deeper into a neighborhood.
So that's the part of the process that is time consuming, it's not so much our technology itself. But it's making the architectural, the wiring, the infrastructure, the rest of the infrastructure changes, both in the central office where you know if you are running our software -- core software on commercial off the shelf servers, you're moving to that server infrastructure, that data center kind of infrastructure, off of old legacy chassis. And very often you're replacing -- deploying fiber deeper on the network.
So that's a time consuming process that also takes capital money as well. And it's that process Simon that for any given operator limits the speed and even the most well heeled operators with a lot of budget. They're not throwing infinite amount of money at this simultaneously. And frankly, in many markets, work crews are somewhat tough to come by etc.
So there is a process of rolling out. That's why we've always said that, even with those customers who we expect to roll out our solution to 100% of their plan. And most of our key customers, we do expect that to be the case, or what we expected to be a several year process, three to four year process.
And so we're on that curve.
As experience becomes better, we expect the pace to quicken, we expect our largest customers to be picking up the pace. And that's the biggest part of the growth. We're projecting this coming year to be clear. But even at a quicker pace, we still expect a several year process for our larger operators to roll out the technology across the entirety of the footprint.
Thanks. And then as a follow up, I wanted to see if maybe we could unpack the gross margin pressure on the cable access segment. And certainly I appreciate you don't have some crystal ball that tells you when the supply chains open up necessarily. But what I'd like to try to understand is, what's the impact of supply chain versus product mix, for example, nodes dilute your gross margin versus your software? We understand that.
So I guess what I'm trying to understand here is what would you expect the gross margin in that business unit should be in a sort of more normalized non supply constrained market? And do you have a view on when we should get back to those levels?
So Simon, I appreciate the question.
I think, as I pointed out in my prepared remarks, there are both pieces to the gross margin. The gross margin decline we are seeing now marginally, is substantially due to the supply chain related costs. At the same time, we are also seeing increased growth in the DAA hardware.
So both pieces are there, it's hard to quantify what is the piece of each, but substantially it's the supply chain costs. That said, once the supply chain challenges are behind us, we should return back definitely in better margins and where we are expecting for this year. And I think not going in outer years.
I think when we talk about the multi-year in our IR event which Patrick mentioned, I think we can cover the expectation at that time. At this point, we are not going into the '22 margins. But directionally we should see improvement from where we are this year.
Is there I guess the level that should we look at fiscal '20 as kind of a normalized value or is that misleading for any reason?
If I could step in, I mean our target is to do better than 2020.
So I don't think it's a normalized value. I mean, maybe if I could from the CEO perspective, look, there's a software component, there's a hardware component, the software component is going to be very high margin, right? It's 90 plus percent. Then we've got hardware. And we've always said, we said previously that the hardware has been let's say, mid 30s, on average. But that is, we expect that to be going up with volume, as well as designer enhancements, etc. And in long-term, that's still our expectation.
I think, yes, we've gone the other way, short-term on the hardware. But that is not a fundamental reset, we're paying a lot more to unpack that a little bit, as you asked, we're paying a lot more for key components. We're also paying higher assembly and transport costs.
So we're kind of getting hit from a number of perspectives. We see none of those hits, though to be off the fundamental impairments to go forward indefinitely. We don't have a crystal ball on this supply chain thing. I mean, right now, I think we expected to kind of carryover somewhat into 2022. But we would expect, again, this is a very clear expectation, but we expect some recovery later in 2022. But we certainly hope it's sooner, we don't have a good crystal ball. But what this guidance assumes is that it will be with us to 2021. And again, I want to emphasize the fact that we could probably have higher margins if we were willing to take a lower deal with lower volumes. But, we see a land grab opportunity, we've got real momentum with our solutions.
So we are leaning in every opportunity, we have to deploy DAA hardware out there, which means we're scouring the planet right now for the materials we need. And we're paying top dollar in many cases for that.
I think that's the right thing to do strategically.
I think capturing real estate is absolutely the right thing in terms of our multi year growth opportunity, our market leadership opportunity. Yes, it's costing us the gross margin short-term. But I think that I think the right way to look at it is, is that we're picking up a significant market share. And that's going to be a durable strategic benefit to the business for many years after this near term cost headwind is behind us.
Great, that's helpful. Thank you. That's what I was looking for. Appreciate it.
You have a question from George Notter from Jefferies.
I guess I wanted to come back to the C-band discussion from earlier.
I think you said you're seeing a broadening out of opportunities, I guess the clarification here. Are you seeing then some of the 2023 opportunities coming forward? Then I guess there's a of course a deadline December 5, I think 2023.
So when you talk about a broadening of opportunities, are those the deals that you're seeing now kind of coming forward? Or? Are there some other pieces of business that are coming forward?
No, we're referring to something a little bit different, George.
Just taking a backup, I know, you know, this, but others listening may not? I mean, still around the world, a huge amount of video is moving around over satellite networks. And I think, in many ways, the philosophy, or philosophy has been out there but [ain't] [ph] growth don't fix it. Even though intellectually, the question has been out there, wait a minute, why not be using, fiber base to transport. And I think what we're seeing is, through the success in what's happening to-date with the C-band project that is causing some of the -- let's call it, [ain't] [ph] growth don't fix it, folks, to stop and pause.
So even in the absence of the government conversion plan or pressure, the success of this initiative is opening the door to a different kind of discussion saying wait a minute, even if the government isn't bearing down on us and requiring us to abandon satellite, maybe moving more of that traffic to fiber is going to save money on one hand. And on the other hand, maybe it's going to allow a more innovative service deliver offer.
So it's the latter that we're referring to not a pull in of government driven programs, but rather, a growing industry dialogue around whether to leverage this technology more broadly. Does that make sense?
That's very helpful. I guess I also wanted to ask about maybe one in RDOF.
So, obviously the list of awardees is out there for phase one. Are there specific operators or customers that you see on that list that are Harmonic customers that create new revenue opportunity for you. Are there specific guides you can identify?
Yes, is the short answer. I don't want to suggest that, we've got a seat right in the front and center of the auditorium. But the short answer is yes. There are people who are existing customers and there are people who are in our sales pipeline.
Now, to be clear, as we've stated, we're focusing on today we're focusing on a subset. Those are the subset of those folks who own some cable infrastructure as well.
So who would be kind of hybrid cable and fiber to the premises operators? But for anyone who is in that category, they're absolutely which is a subset of the RDOF awardees. They're absolutely part of our go-to-market focus.
And you have a question from Steven Frankel from Colliers. Mr. Frankel, check to see if your line is muted.
There we go. Patrick, thank you for the opportunity to what extent is this acceleration in R&D reflecting kind of new projects that you think you need to get to market faster versus kind of just accelerating the pace around existing things you have already targeted?
I wish it was one or the other, it's a mix of both. We do have -- look to be frank, I think we've said it before every tier one has their own unique stuff. And part of the success formula is kind of adapting before them. And we've got, we announced a significant tier one last quarter, we've added another one this quarter. And we've got several more tier ones in our pipeline. And we're planning for success with the ones we've recently signed and with the ones that are coming.
So there's part of it. But the second part of this is, it's not for looking, what we're learning in existing deployments, what we're seeing the fiber of the home opportunity, we've talked about a couple of times and the overall momentum and we're envisioning where the puck is headed and we see the puck really moving down the ice if I can stick with that analogy.
And so we think now is the time to -- is to really lean in. I mean, let's face it, if we spend on R&D in that regard now, it shows up as benefit, later in '22 or in 2023. And we've got real growth aspirations for those years.
And so we think now is the time.
Well, and then one follow up.
I think I heard you say before that DAA is increasing in mix and it's coming from the tier ones.
So is it fair to say that those tier one customers that were kind of dipping their toe and doing fits and starts over the last 18 months, are now far enough into it, that they can kind of put their foot on the accelerator in terms of deployments?
Yes, the pace of employment is definitely increasing.
I think that's one thing.
I think the other thing is, is that a couple of those operators initially started off with several different DAA sources. And we think we're getting a little bit higher market share because of the strength of our particular solution. And again, even at short-term, higher cost, we think the right thing to do is to lead into that, let's call it incremental market share opportunity. We view putting a DAA node out there is gaining valuable real estate. And not just a short-term, or not just a short-term revenue opportunity but a real presence in the network opportunity but that is where we're leaning into.
And you have a question from Tim Savageaux from Northland Capital.
I'm trying to be quick here. Got a couple questions.
First, the overall topic of deployment accelerating in cable and trying to bridge the gap between 3 million cable modems and 50.
I think you commented at a recent industry event that you thought that number would be nine or so by the end of this year, which is a pretty market acceleration. In that context, interesting to see that the guidance increased I mean, understanding there may not be a linear relationship between that type of acceleration and cable modem served in Harmonic's revenue. Should we -- sounds like, we should be thinking more about the high end of the range where you mentioned 50% growth or even that's conservative in light of those targets. And then I have a follow up on a completely separate one.
Well, thanks for the question, Tim.
I think you're referring to comments that I made at a recent industry event, which is really targeted at the cable operator community. And they are -- I was not talking specifically about Harmonic but the industry at large. And as I think while think we're ahead of the class on DAA, there are a couple of others who are doing DAA solutions, including DAA solutions that are not tied to virtualized CMTS, etc.
So the estimate that I provided there was not a Harmonic number, but it was an overall industry number, domestic as well as international and certainly, therefore included a competitor DAA solutions that are out there.
So yes, there's a couple of different variables floating around. And further, I will also concede that discussing, growth forecasts with the industry is somewhat different than offering financial guidance.
So you've got a couple of different things going on.
I think the good news is, we are seeing the industry get more and more comfortable with DAA as a technology. And I think, important thing that came out of that live reading conferences is increased industry conviction, the DAA is not only viable, but it's actually increasingly is the way to go. But yes, one can therefore not draw a straight line between those industry projections and our revenue for a couple of reasons, as you highlighted as well as what I've just said, in terms of overall industry numbers versus Harmonic's.
Okay. Did say you thought you were gaining share, but I'll just leave that one there.
Second one is, I think there was a brief reference made maybe in the incentive comp, discussion about part of the driver of that being the new kind of cooperation agreement or the board changes that you've seen. And, I wonder if you might comment a little more expansively on that we also, I'm going to guess that the more detailed segment guidance and Investor Days might be a function of that as well. And I guess at a high level, should we be thinking about these segments increasingly, separately, for Harmonic video and cable access, both tactically and strategically. And if that were the case, it might make for a shorter press release, at least, or possibly a shorter call. But your choice for how to approach it, whether we should be thinking more about strategic activity at Harmonic as a result of that agreement and what has been the impact to-date, besides what you've mentioned on the call?
So, let me start with the first one, let me clarify this change, of incentive comp from stock to cash has nothing to do with the cooperation agreement. This is purely internal decision.
As the Board looked at our plan for the year, we are generating very good cash and the operating profit level we are reaching, we took a decision to convert a piece of over stock comp to cash comp and it helps marginally reduce the valuation of the company as well.
So let me clarify, it has nothing to do with that agreement.
Secondly, in terms of the two segments being distinct, we have always reported the two segments, right from the revenue to the operating profit in actual reported results. But while giving the guidance, we have not given the guidance in that transparency, starting this quarter, we felt the need to do it based on the continuous regular questions during the industry interactions we've had.
So we thought it's more transparent and it provides more visibility of what each segment is doing. And again, this has also nothing to do with any other agreement.
So this is more on transparency.
And Tim just maybe a follow on from my perspective, where we truly as a cooperation agreement, we value relationship with Scopia, they've been in the stock for several years, and that's all very good and so that's full statement full stop. Separately, I think along the lines of Sanjay just said, we've been quite clear over the past several years, about how we think about the different pieces of our business and how we're trying to create value in the company. And there really is no strategic change. And it wouldn't be a mistake to conclude anything strategically from anything that we've discussed today. Both of our businesses, we think, have exciting futures and opportunities you can see that we're investing in both. And we've been quite transparent, we've received the question numerous times over the past several years, what's the level of synergy between the two, we've been quite transparent to say, there's modest synergy. It's not overwhelming. The way the company, the management team, as well as our Board will work to create value whatever way we can, that maybe what the two business units saying together and maybe what the part, there's no change in that answer nor in our thinking that has over the past several years.
We will continue to move forward, looking to create as much value as we can and overall enterprise, which really means creating as much value as we can in the two business segments. And I'm very pleased coming into this call that we see actually good strategic progress on both sides of the business.
I think there's a lot of reason to be encouraged on both sides and to see a good future so on both sides of the business.
And there are no further questions at this time. I'm going to turn the call back over to management for closing remarks.
All right. Well, thank you very much all for joining us. We've got a lot of challenges, but a lot of opportunities ahead of us. We look forward to staying in touch with all of you and in particular, as mentioned, keep an eye out for our planned investor dates in a month or so time. Until then, take care and we look forward to speaking with you all again soon. Bye-bye.
Ladies and gentlemen, this concludes today's conference call. Thank you for participating.
You may now disconnect.
