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 have 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 the 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, Nimrod Ben-Natan. Nimrod.

Nimrod Ben-Natan (Chief Executive Officer and President)

Thanks, Scott, and welcome everyone to our third quarter 2026 earnings call. This is our first call since our September Investor Day where we laid out a strategy built on three growth engines: Connectivity, Intelligence and Edge AI. Compute AI is produced in data centers, but it is experienced over broadband as it moves into homes, businesses and billions of connected devices. The network has to deliver more capacity, lower latency and higher reliability.

AI agents already generate a large and fast-growing share of Internet traffic. What’s new this quarter is that the largest AI platforms began launching always-on personal assistants that work around the clock, interacting with us and with the connected devices in our homes. That means more sessions, more upstream traffic and tighter latency demands on home broadband. At the same time, broadband remains hyper competitive. Operators are fighting for every subscriber so they need to deliver the best customer experience while keeping operating costs in check. That is the role of Intelligence and Sensei, which I will cover shortly. Whether operators need more capacity or an enhanced quality of experience and more efficient operations, they are turning to the virtualized distributed architecture we pioneered and the intelligence we’ve built on it.

Now let’s discuss third quarter. It was another quarter of strong execution and a breakout with our revenue grew 64% year over year to $148.8 million, well above the high end of our guidance. Rest of Market revenue more than doubled year over year to reach a record 46% of total revenue. That’s the trend we highlighted at Investor Day and it puts us on track for Rest of Market to become the majority of our business. Rest of Market also represented over 60% of our bookings in the quarter.

Reflecting this performance and a more favorable environment, we are once again raising our full year 2026 outlook. We’re also continuing to expand our customer base. In the third quarter we added nine new customers across seven countries spanning DOCSIS and fiber and including telco operators. Three of them are regional tier one operators. Liberty Latin America, which serves more than 20 countries and territories across Latin America and the Caribbean, selected us for DOCSIS and fiber. TDC, Denmark’s largest telecommunication and digital infrastructure company, selected our platform for a unified DOCSIS 4.0 upgrade, and we also signed a tier 1 operator in Belgium.

We also added Bacom, a major regional cable and broadband operator serving Japan’s Osaka metropolitan area, and Fibex, a fiber broadband operator expanding high-speed connectivity across Venezuela. We continue to lead in DOCSIS and to extend that leadership position. Our deployed cOS footprint now includes 167 customers serving almost 53 million CPE devices, and unified DOCSIS 4.0 is now shipping in volume with a growing number of operators. cOS is also helping operators compete for multi-dwelling units, one of the most competitive segments in broadband. In Washington State, Lightcurve used cOS and our compact Oyster node to deliver 8×1 gigabit per second service over existing in-building coax, giving MDU residents fiber-like speeds without a costly fiber overbuild while keeping the option to add fiber later.

And earlier this month, Cablenet, the second largest fixed network operator in Cyprus, announced it is modernizing its access network on cOS, consolidating data centers and hub sites to lower operating costs while improving the subscriber experience. Fiber momentum continued as well. Pearl 1XL, introduced earlier this year, is now shipping in volume and we booked another strong quarter for it in the quarter. Oyster Plus is ramping too, giving operators a compact, power-protected way to extend fiber without a street cabinet. We also acquired a vendor-agnostic fiber management and provisioning platform this quarter and rebranded it cOS Loop. Loop is performing well with its established customer base in Brazil and we’re seeing strong interest from Harmonic customers in North America and Europe.

Intelligence was also a big part of our quarter. In September we launched Sensei, an open intelligence fabric that works across any network and any vendor, turning data from every system into decisions operators can act on. Sensei came to market after extended trials with operators and customers. Feedback has been very strong. We are now in the next stage. New wins and the migration of our existing cloud customers onto Sensei have already begun. At SCTE Tech Expo we demonstrated Sensei running live on a production network, finding issues inside the home and out in the plant on DOCSIS and fiber regardless of vendor, and it is already delivering value at one operator. Sensei pinpointed in about 10 minutes a field issue the team had chased for 10 days, then caught another fault further down the same line. Our installed intelligence base also grew with Beacon now live at 25 operators, up from about 20 last quarter.

And now that cOS Loop is part of Harmonic, we have integrated its data into Sensei and launched proof of concept with a handful of Loop customers. We also launched Recon, developed with Comcast, which brings fiber monitoring technology proven in Comcast’s network to cable and fiber operators alike. It gives operators real-time visibility across their fiber, spotting degradation and fiber cuts before customers notice and pinpointing where to fix them.

And because it integrates with Sensei, small issues are stopped before they become outages. Let me now turn to Slide 5 and give you our first quarterly update on the three growth engines we outlined at our Investor Day, which together represent a total addressable market opportunity of more than $7 billion by 2030. We will report on each of them every quarter. Connectivity is our core market, representing roughly $5.4 billion of that opportunity. Our strategy is to address it on one cOS platform, extend our leadership in DOCSIS, continue taking our fiber portfolio beyond cable into telco, and get ahead of the move to 50 gig for telcos.

Our OLT portfolio, including hardened remote OLTs and our open ONT approach, provide the interoperability and supply choice they want, and with cOS Loop our fiber offering is now end to end and works across multi-vendor networks. Our differentiated 50 gig solution received very positive feedback at recent industry events and is on track for introduction in 2027, positioning us for the next wave of fiber investment. Intelligence is our newest growth market and the timing could not be better. In a hyper-competitive environment, operators win and keep subscribers on reliability and experience, and they have to do it without adding cost. That is exactly what Sensei is built for, and with Recon and cOS Loop feeding it, our intelligence portfolio now spans DOCSIS and fiber from inside the home to the broader network. Our strategy is to turn our installed base into a natural on-ramp for Sensei revenue.

Starting this quarter and running through 2027, we are migrating all of our premium cloud customers onto Sensei so when they choose to expand into its full capabilities there is nothing new to deploy. With an expanding Sensei pipeline, we remain on the path we outlined at the Investor Day. We expect Intelligence to reach about 10% of revenue over the next three years, adding a new and growing recurring revenue stream for Harmonic. Edge AI compute is our third growth engine and it represents potential upside to our long-term model. As operators modernize with cOS, they free up space and power in facilities that sit milliseconds from their subscribers and businesses. This quarter our largest customers highlighted where edge AI compute is heading. One began live streaming from more than 200 edge compute sites inside its network and another announced commercial edge AI partnerships on compute it can activate across more than 1,000 facilities.

Our opportunity is to bring this capability to the broader market using cOS as the orchestration layer and we are in development with key customers and partners. That concludes my opening remarks. With that, I will turn the call over to Walter to walk through our financials in more detail.

Walter Jankovic (Chief Financial Officer)

Thanks, Nimrod, and thank you all for joining us today. Before I discuss our quarterly results and outlook, I’d like to remind everyone the financial results I’ll be referring to on this call are provided on a non-GAAP basis. As Scott mentioned earlier, our Q3 press release and earnings presentation include reconciliations of our non-GAAP to GAAP financial measures. Both of these are available on our website. I’m pleased to report that we had a breakout third quarter with revenue increasing 64% year over year to 148.8 million, which far exceeded the high end of our guidance. This included over 100% growth in rest of market. In addition, we closed the quarter with backlog and deferred revenue of 534 million, up 58% year over year. Notably, over 60% of bookings in the quarter came from rest of market. Given these results and a strengthening demand environment, we are once again raising our full year guidance with revenue now expected to be between 545 and $555. million, up from our prior range of 505 to $525 million. I’ll provide a more detailed breakout of our guidance shortly. Let’s move to slide seven where we have the financial highlights for the quarter. Revenue was 148.8 million, well above our guidance range of 125 to 135 million. Gross margin for the quarter was 52.1%, just above the high end of our guidance range, inclusive of net unrecovered memory costs of less than 3 million.

Operating expenses were 44.5 million, above our guidance range mainly due to performance-based incentive accruals tied to our improved full year 2026 financial performance forecast and earnouts associated with our Q3 tuck-in acquisition of a vendor-agnostic fiber management and provisioning platform. OPEX also reflects the completion of a multi-year custom development project in Q2. The engineers on this program were previously charged to cost of revenue and are now in R&D assigned to other products, which adds approximately 2 million per quarter to operating expenses starting in Q3.

Moving to the bottom line, EPS was $0.23, well above our guidance range of $0.15, and operating profit was 33 million, exceeding our guidance of 23 to 28 million. These results include 1.5 million in stranded costs related to the video business sale, net of TSAs. The revenue upside was broad-based and included a number of rest of market customers ramping their deployments during the quarter as well as a seasonal increase in our outside plant services business.

In Q3, four customers each accounted for more than 10% of revenue. Our top two customers represented 54% of total revenue. Combined, our Q3 rest of market revenue showed very strong year-over-year growth of 101% and sequential growth of 39% and represented 46% of total revenue, highlighting our expanding customer diversification. As a reminder, rest of market revenue describes all revenue that is not from our two largest customers as measured by subscriber count.

Turning to slide 8, you can see our balance sheet and cash flow highlights. Our sequential cash change was largely due to a $75 million repayment of borrowings under our revolving credit facility during the quarter, leaving $160 million available under this facility at October 2nd. Additionally, we had negative free cash flow of 5.1 million for the quarter, which was due in part to a continued increase in inventory, including memory, as we took delivery to secure supply for growth and an increase in receivables.

DSO at the end of Q3 was 71 compared to 61 in Q2 26 and 61 in Q3 25. As we stated on past calls, we expected DSO to trend back to the low 70s based on our customer mix and timing of revenue. Inventory increased 28.3 million in the quarter and our days inventory on hand increased to 120 days from 95 days last quarter. This too was expected as we support growth and secure supply. Our overall book-to-bill was 0.7 in Q3 with rest of market book-to-bill around 1.0.

Q3 has traditionally been a lower bookings quarter for the business. As we have said before, we expect book-to-bill to fluctuate from quarter to quarter but over time to return to our historical benchmark of greater than 1. Reflecting the growth in our business, at the end of Q3 backlog and deferred revenue was 534 million, up 58% year over year and down from 587.6 million in Q2 on seasonally lower bookings, of which 72% is expected to convert to revenue within the next 12 months.

This gives us increased visibility for the remainder of 2026 and into 27 as shown on slide 9. We continue to believe we have ample liquidity to support our capital allocation priorities, with 143 million in cash and 160 million undrawn credit facility. We repaid 75 million under our revolving credit facility in the quarter to reduce interest costs while keeping the full 160 million available to us. This total available liquidity gives us the financial flexibility to execute our capital allocation plan. Our capital allocation priorities remain unchanged: invest in organic growth and diversification, return capital to our shareholders, and pursue strategic M&A to accelerate our growth strategy and diversify our business.

In line with our first key priority, we plan to keep investing in organic growth. Organic opportunities exist in both our Intelligence Platform business and Fiber portfolio, including 50Gig, as well as in the new markets we outlined during our recent investor day. We will also continue to invest in inventory over the next several quarters, including advancing memory and other purchases to secure supply. Under our current $200 million share repurchase program, to date, we’ve already repurchased $142 million of our shares, including $4 million of shares during the third quarter and $16 million following the end of the third quarter.

As we stated previously, we expect to fund ongoing repurchases through both current cash and strong free cash flow generation over the next several years, with a minimum goal of purchasing enough shares each year to offset any dilution from equity compensation awards. In addition, with our substantial cash position and available liquidity, we’re well positioned to explore additional inorganic growth opportunities that would accelerate our growth and diversification strategy, including scaling our Intelligence Platform.

In Q3 we completed the tuck-in acquisition of a vendor-agnostic fiber management and provisioning platform company referred to now as Cos Loop. Turning to guidance on slide 10, here we provide our continuing operations non-GAAP financial guidance for Q4 26 and full year 26, which reflects our raised full year 2026 outlook. We continue to take a measured approach to guidance for both revenue and margins. We believe this is prudent given external factors such as the situation in the Middle East and secondarily component supply dynamics and pricing. Our full-year margin guidance incorporates the current market pricing for memory.

Now let me walk you through the guidance for Q4 26: we expect to deliver revenue between 141 and $151 million, gross margins between 51 and 52% reflecting elevated memory costs, operating profit between 28 and 34 million, and EPS between 19 and 23 cents. As our guidance shows, we expect strong year-over-year revenue growth to continue in Q4 26 at approximately 49% at the midpoint. Q4 operating profit includes approximately 1.5 million in stranded costs.

For the full year 2026 we expect revenue between 545 and 555 million, up 35 million or 6.8% from the midpoint of our prior guidance, gross margins between 52.1% and 52.4% up from 51 to 52% previously guided, operating profit between 118 and 124 million, and EPS between $0.80 and $0.84, up approximately $0.11 or 15.5% from the midpoint of our prior guidance. This is the third time this year that we have raised our full year outlook. Compared to the full year outlook provided at the start of the year in February, our current full year outlook at the midpoint reflects a revenue increase of approximately 20% and EPS increase of 50%.

This demonstrates the momentum that has been building in our business. In addition, with minimal debt and a net cash position, changes in interest rates have little impact on our earnings. As we noted last quarter, we’ve built in approximately 3 million in Q4 for net increased memory costs that are not expected to be passed on. Our team has done a terrific job securing memory supply for the rest of 2026 and well into 2027. We believe the current challenging supply and cost environment will persist into 2027. Beyond memory, we are beginning to see other component costs rising through 2027, and we plan to mitigate these cost pressures by passing through increases to customers where appropriate.

Additionally, full year operating profit now includes approximately $7.6 million in stranded costs, down from our prior estimate of $10 million. And to reiterate what we said on prior earnings calls, we continue to believe approximately 30% or more of the original $10 million of stranded costs are temporary and will be eliminated by the end of Q2 27. Please note that our expected non-GAAP tax rate for full year 26 remains at 23%. In summary, in the third quarter we delivered results that once again significantly exceeded our guidance, with revenue growing 64% year over year. Our strong backlog and deferred revenue and secured supply give us increased visibility, enabling us to once again raise our full year 26 guidance. Thank you for your attention, and now I’ll turn it back to Nimrod for closing remarks before we open up the call for questions.

Nimrod Ben-Natan (Chief Executive Officer and President)

Thanks Walter. To close, Q3 marked another quarter of strong execution and a record-setting one. Revenue was up 64% year over year. Rest of market was a record 46% of total revenue. We signed nine new customers, including three regional tier 1s, and we made real progress on each of our three growth engines. And as a result of all of this, we are once again raising our full year 2026 outlook. Our long-term growth rests on four: technology leadership, an expanding addressable market, a strong operating model, and proven execution. This quarter we delivered on all four of these, and operators keep choosing Harmonic because we let them evolve their networks from DOCSIS to Fiber to Intelligence and the edge on one platform. That concludes our prepared remarks. Walter and I are now happy to take your questions.

OPERATOR

Thank you. We will now begin the question and answer session. As a reminder, if you wish to ask a question, you will need to press Star 11 on your telephone and wait for your name to be announced. To withdraw your question, please press Star 11 again. We will take our first question, and your question comes from Simon Nippold from Raymond James. Please go ahead. Your line is open.

Simon Nippold (Analyst at Raymond James)

Thank you very much for taking the question. First, just a quick clarification, if I might, and then the question. You mentioned 54% of revenue from your top two customers. I want to confirm that these are the same top two we’ve seen, and if you might be able to give us the breakdown between those two. And then the question I wanted to ask about is regarding what I would characterize as at least a perceptual threat of competition to your customers coming from satellite. I want to get your perspective on how you’re hearing and what you’re discussing with your customers as far as their need to upgrade, and cable versus telco versus satellite as an alternate broadband provider. Thank you.

Walter Jankovic (Chief Financial Officer)

Hi Simon, it’s Walter. I’ll take your first question with regards to the top two customers. Those are always the same top two because it’s based on the highest subscriber count. And in the quarter, as we mentioned, they were 37 and 16% in terms of those two customers.

Nimrod Ben-Natan (Chief Executive Officer and President)

And Simon, to your question about the competitive environment, it’s hyper competitive and it is very competitive on the fixed wireless and on fiber in different geographies. I think the satellite broadband is mostly in rural areas. You definitely see that less in the urban, kind of more densely populated areas. Regardless, we see our customers really focusing on making sure their network is competitive, making sure they provide the best quality of experience.

And they do all of that at the lowest possible cost. They want to make sure that they don’t kind of break the envelope of their operating environment. So in summary, the satellite broadband by itself does not change the investment or priorities that we’re seeing. It is simply sharpening the focus that they have on what they need to do.

OPERATOR

Thank you. Thank you. We will take our next question. And the question comes from Steven Frankel from Rosenblatt Securities. Please go ahead. Your line is open.

Steven Frankel (Analyst at Rosenblatt Securities)

Thank you and congratulations, Walter. You’ve shown some good resilience on gross margin. How would you attribute that? How much of that is buying well ahead of time versus maybe pricing or product mix as we move forward, incorporating Q4 as well as you think about that, because that guidance seems a little higher than at least I was anticipating.

Walter Jankovic (Chief Financial Officer)

Yes, Steve. So with regards to, you know, the memory cost, what you’re seeing in both Q3 and Q4 is now the elevated level of cost for memory. So think of it as kind of the market price that’s out there for memory. So we did front-run a lot of memory, and that benefited us in the first half of the year. Now, we’ve continued to see memory prices going up even from the levels that, let’s say, were at in the Q3–Q4 time frame. However, that increase is marginal compared to what we had seen earlier in the year when we were stockpiling memory to facilitate the supply for this year as well as into 2027.

So the way I think about the margins right now, you see, Q3 and Q4 are kind of similar in that range that we’ve provided previously. And in both quarters, we are anticipating in Q4 again about a $3 million impact as a result of those elevated memory costs. And as we think about next year, we’ll continue seeing that kind of level of cost, if not a little bit higher than that in memory. I think one of the other things I mentioned in the prepared remarks today is that we’re also seeing other component costs increasing as we go through 2027.

And as I mentioned in the remarks, we expect to mitigate that by passing that on to customers as appropriate.

Steven Frankel (Analyst at Rosenblatt Securities)

Okay. And could you give us an update on the fiber customer count?

Nimrod Ben-Natan (Chief Executive Officer and President)

We did not break down the fiber customers out of the total that we provide every quarter. The total itself is broken down into three categories: cable only, cable and fiber, and fiber only. But we don’t break them down. Out of the nine that we announced this quarter, there is a handful that are fiber customers. And our fiber business is expanding with existing customers as well.

Steven Frankel (Analyst at Rosenblatt Securities)

Great, thank you. I’ll jump back into the queue.

Nimrod Ben-Natan (Chief Executive Officer and President)

Great. Thanks, Steve.

OPERATOR

Thank you once again. If you wish to ask a question, please press star one one on your telephone. We will take our next question. And the question comes from George Notter from Wolfe Research. Please go ahead. Your line is.

Darren (Analyst at Wolfe Research)

Hey, guys, it’s Darren, on for George. Thanks for taking the question. Can you talk a little bit about what components you’re seeing price increases, and then kind of on the tail end of that, to what extent do you expect to raise pricing on those? It sounds like this is more of a ’27 event.

Walter Jankovic (Chief Financial Officer)

Yes, certainly. As we are looking forward and working with the supply base, we’re seeing components going up in terms of key silicon, as well as items like PCBs and other components across the board. It’s something that we’re very focused on as we go through 2027. And as I mentioned, you know, our expectation is to, you know, raise prices accordingly for the increases that we’re seeing in some of these key components.

Darren (Analyst at Wolfe Research)

Okay, got it. And then just one last question here. To what extent do you intend to make more memory purchases? Because it sounds like you guys are going to continue pursuing that even though you have inventory well into ’27. What’s your strategy there?

Walter Jankovic (Chief Financial Officer)

Our strategy has been to stay way ahead of it in terms of making sure we’ve got supply for our customers to be able to fulfill the increasing demand that we’re seeing across all of our customer base, as you’ve seen today, definitely increasing in terms of the rest-of-market revenue and customer base. So we are staying ahead of it in terms of going ahead so many quarters and picking up memory to ensure that we’ve got the supply. And as in the earlier question, by getting ahead of it, it’s actually saved us some money as those commodities have increased in cost.

Darren (Analyst at Wolfe Research)

For sure. Thank you so much.

Walter Jankovic (Chief Financial Officer)

Thank you.

OPERATOR

Thank you. There are no further questions. I will now hand the call back to management for closing remarks.

Nimrod Ben-Natan (Chief Executive Officer and President)

We appreciate your continued interest in Harmonic and look forward to updating you on our progress in the future. Thank you all for joining the call. Have a good day.
