readyJun 10, 2026

ADTRAN delivered solid Q1 2026 results with 15.5% YoY revenue growth and non-GAAP operating margin expansion to 6.9%, driven by strength in optical networking (up 24% YoY) and subscriber solutions (up 22% YoY). Management highlighted progress in high-risk vendor displacement in Europe, early traction in AI infrastructure via Mosaic One Clarity and LightWave 800, and improving demand from B funding in the U.S. However, the business remains dependent on seasonal patterns and external factors like freight costs and memory pricing, with no meaningful updates on backlog conversion or customer concentration.

Management knows today that the LightWave 800 product is a real, working prototype with strong early engagement from large, well-known customers, and that production-level volume is expected approximately one year from now due to semiconductor-type scaling challenges. This timeline and customer validation are not yet reflected in the market, as the product remains in pre-production with no revenue contribution expected until late 2027 at the earliest. The market likely will not know the true adoption rate, pricing power, or margin profile of this product until volume production begins and early customer deployments are validated in 6-24 months.

Revenue growth driven by optical networking solutions, access and aggregation, and subscriber solutions; operating leverage from disciplined cost management and favorable product mix; demand tailwinds from high-risk vendor displacement in Europe, B funding deployment in the U.S., and AI/cloud infrastructure connectivity needs.

  • LightWave 800 development and market reception
  • High-risk vendor displacement in Europe and Cybersecurity Act 2.0
  • B funding deployment and timing in the U.S.
  • AI infrastructure opportunities via Mosaic One and edge platforms
  • Optical networking demand from cloud and hyperscaler customers
  • Gross and operating margin expansion drivers
  • LightWave 800 described as 'ridiculously low power' at one picojoule per bit, an industry first
  • Strong validation of Mosaic One Clarity with FTTH Europe Award for AI innovation
  • Early deployments of AI edge platform receiving 'overwhelmingly positive' feedback from 150+ customers
  • Fantastic market reaction to LightWave 800 from large, well-known customers
  • Quattro product positioned as better than anything on the market today for power savings

Management exhibited a direct and credible tone, providing specific technical details (e.g., one picojoule per bit for LightWave 800) and acknowledging limitations such as inability to break out cloud revenue or provide BID estimates. They avoided overpromising on timelines (e.g., LightWave 800 production 'about a year from now') and clarified uncertainties around freight, memory costs, and product ramps without evasion. Their discussion of gross margin drivers and cost discipline was consistent with financial results, reinforcing credibility.

  • No clear dodged analyst question was detected by the local fallback; manual review should still check whether Q&A answers quantified conversion, margins, and guidance.
  • There may be a benchmark or metric-framing issue worth manual review, especially around adjusted metrics, timelines, or changed expectations.

The company appears to be winning in specific niches: high-risk vendor displacement in Europe, early leadership in AI-driven network operations (Mosaic One), and power-efficient optical interconnects for AI data centers (LightWave 800). However, without data on market share, customer concentration, or direct competitive comparisons, the overall competitive position is not fully assessable from the transcript alone.

  • Q1 2026 revenue: $286.1 million, up 15.5% year-over-year
  • Non-GAAP operating margin: 6.9%, up 300 basis points year-over-year
  • Optical networking solutions revenue: $97.3 million, up 24% year-over-year
  • Subscriber solutions revenue: $98.2 million, up 22% year-over-year
  • Access and aggregation solutions revenue: $90.5 million, up 2% year-over-year and 14% sequentially
  • Non-GAAP gross margin: 43%, up 55 basis points year-over-year
  • Production ramp of LightWave 800 expected ~1 year from now (late 2027)
  • Continued rollout of B funding in U.S. states driving subscriber solutions revenue in back half of 2026
  • Expansion of high-risk vendor displacement in Europe reinforced by Cybersecurity Act 2.0
  • Growing demand from cloud and hyperscaler customers for optical interconnects
  • Early adoption of Mosaic One and IntelliFi software platforms with growing subscription base
  • Potential for power-saving technology from LightWave 800 to proliferate in pluggable product family
  • Revenue remains subject to seasonal patterns, with sequential strength offset by declines in smaller customers and government sales
  • Freight costs remain elevated and are not expected to improve materially in Q2 2026
  • Memory pricing remains elevated industry-wide, affecting lower-margin CPE products
  • No visibility on customer concentration or specific cloud/hyperscaler revenue contribution
  • LightWave 800 production timeline is approximately one year away, with no near-term revenue contribution
  • B funding impact in U.S. remains early-stage, with only a trickle of purchase orders seen so far

ADTRAN has direct exposure to data center growth through its optical networking solutions, particularly via the LightWave 800 product, which is purpose-built for intra-data center connectivity in high-density AI compute environments. The company cites surging demand from cloud providers and hyperscalers for wholesale optical capacity and AI infrastructure connectivity as a key tailwind. While still early, initial market engagement on LightWave 800 has been encouraging, and the product is designed to reduce power consumption by over 90% compared to existing alternatives. This positions ADTRAN to benefit from AI-driven data center expansion, though volume production is not expected for approximately one year.

  • What is the expected revenue ramp and margin profile for LightWave 800 upon volume production in late 2027?
  • What percentage of total revenue is derived from cloud and hyperscaler customers, and is this growing?
  • What are the specific milestones and timing for B funding conversion to revenue in the U.S. beyond purchase orders?
  • How will the power-saving technology from LightWave 800 be integrated into other product lines, and what is the timeline for broader impact?
  • What is the current customer concentration risk, particularly among top 5 optical or cloud customers?
  • How sustainable is the 6.9% non-GAAP operating margin given ongoing freight and memory cost pressures?
  • What is the expected impact of the Cybersecurity Act 2.0 on European revenue timing and volume?
  • What is the attachment rate and upsell trajectory for Mosaic One and IntelliFi among existing customers?

AdTran Holdings assumes no obligation to update any such forward-looking statements. During today's call, management will refer to certain non-GAAP financial measures. Reconciliations of GAAP to non-GAAP measures and certain additional information are also included in our investor presentation and our earnings release. AdTran Holdings has not provided reconciliations of its second quarter 2026 outlook with regard to non-GAAP operating margins because it cannot predict and quantify without unreasonable effort of all the adjustments that may occur during the period. The investor presentation has been updated and is available for download on the ADTRAN Investor Relations website. Hosting today's call is Tom Stanton, ADTRAN Holdings Chief Executive Officer and Chairman of the Board, and Timothy Santo, Senior Vice President and Chief Financial Officer. It is now my pleasure to turn the call over to Tom Stanton, Chief Executive Officer of ADTRAN Holdings. Sir, please go ahead. And Tom Stanton, I turn it over to you. Tom Stanton | Chief Executive Officer and Chairman of the Board: Thank you, Kayla. Good morning, everyone. AdTrend delivered solid first quarter results with revenue of $286.1 million, up 15.5% year-over-year, and non-GAAP operating margin of 6.9%, up 3% year-over-year. These results reflect the continued strength of our core markets and the operating leverage we have now firmly established across the business. The demand drivers underpinning our business continue to strengthen. In the U.S., broadband expansion is gaining traction, and DB deployment funds are beginning to reach operators in a growing number of states. In Europe, high-risk vendor displacement continues to progress, with momentum reinforced by legislation such as the proposed Cybersecurity Act 2.0, which would mandate the removal of high-risk vendors from critical network infrastructure. This quarter also marked a meaningful step in our growth strategy as we showcased our expanding portfolio addressing cloud and AI infrastructure connectivity. This included the introduction of the LightWave 800, a solution purpose-built for high-performance, low-power intradata center connectivity. Optical networking solutions revenue was $97.3 million in the first quarter, up 24% year-over-year. On a sequential basis, strength from our larger customers and hyperscalers was offset by seasonal declines with smaller customers and government sales. Across our service provider base, demand remains healthy. Operators across all geographies are expanding wholesale optical capacity to support growing demand for cloud connectivity and higher bandwidth services, reflecting a broad-based trend. In Europe, high-risk vendor replacement initiatives continue to add to that demand, with growing strength among our cloud and hyperscaler customers and a positive outlook across our service provider base. We expect our optical networking revenue to build throughout the year. Access and aggregation solutions revenue was $90.5 million in the first quarter, up 2% year-over-year and 14% sequentially, driven by broad-based strength across the U.S. and Europe. We expect steady progress across our European business through the remainder of the year. In the U.S., B deployment funding is beginning to reach operators in select states, And while we are seeing early orders from several customers, we expect the impact to become more meaningful as we move towards the back half of the year. Subscriber Solutions revenue was $98.2 million in the first quarter, up 22% year-over-year. Demand remains healthy, supported by continued investment in fiber to the home, multi-gig Wi-Fi 7, and carrier Ethernet applications. In recent weeks, our award-winning SDG Wi-Fi 7 portfolio received conditional FCC approval exempting our platforms from covered list restrictions. We are among the first vendors to achieve this designation, and while the broader industry works through the approval process, we are already seeing service providers engage with us on competitive opportunities that this creates. Stepping back from the details for the quarter, I want to take a moment to talk about our business and the market dynamics that continue to drive demand for our solutions. Service providers are investing across transport, access, and subscriber platforms to scale their networks for long-term demand and improved reliability. These investments are being reinforced by several important tailwinds, including high-risk vendor replacement initiatives in Europe, the expansion of managed optical fiber networks, or MOFIN, to address surging demand for wholesale services from cloud providers, and continued upgrades across access and subscriber networks to support multi-gig service delivery. In addition to these network upgrade catalysts, operators are in the early stages of transforming how they operate their networks and engage subscribers through agentic AI. With the launch of Mosaic One Clarity, which recently received the FTTH Europe Award for AI innovation, we are addressing the shift towards proactive and increasingly autonomous network operations. Early deployments have provided strong validation of these capabilities across both small and large operators, particularly in the areas of predictive maintenance and improving the in-home subscriber experience. Beyond our core service provider business, we continue to see meaningful opportunities to further accelerate growth by expanding our presence in both cloud providers and enterprise customers. These segments benefit from many of the same underlying trends shaping service provider networks, but they are growing at a faster pace and are driving new network architectures and requirements. In the enterprise space, we have a long history of providing secure optical and ethernet connectivity to some of the world's largest enterprise and government customers. Demand in this customer segment is increasingly shaped by two important tailwinds. First, the expansion of AI workloads across secure enterprise environments is driving demand for higher capacity interconnects between private enterprise data centers, and second, growing awareness of the limitations of traditional security mechanisms is accelerating interest in quantum safe, optical, and Ethernet communications. Building on our longstanding presence in these markets, we have developed a comprehensive portfolio of quantum safe communication solutions. While still early, we are seeing increasing engagement across a broadening base of enterprise, government, and utility customers positioning us well for longer-term growth as these initiatives mature. In our cloud provider customer segment, the rapid expansion of AI compute infrastructure and the networking required to connect large-scale cluster GPU deployments is driving a surge in networking investment, making this the fastest growing segment in our industry. Data center operators are scaling capacity to support AI workloads where power efficiency, thermal constraints, and network density have become defining design considerations. We have long-served data center customers through our interconnect solutions, and as evidenced by last quarter's results, that business continues to benefit from growing demand for data center connectivity. Our strategy is to build on that foundation and extend our portfolio to address surging bandwidth demands from inside the data center as well. LightWave 800 is the first clear example of this strategy in action. It is purpose-built for intra-data center connectivity and high-density AI compute environments and is designed to reduce power consumption by over 90% compared to existing alternatives. We are still in the early stages of this product family, but initial market engagement and feedback have been very encouraging. Shifting from our market opportunities to operations, memory pricing has remained elevated industry-wide and freight costs are adding an additional layer of pressure. headwinds that are affecting the entire sector. Despite these pressures, our non-GAAP operating margin of 43% reached its highest level since the beginning of the supply chain disruption in 2020. This was achieved through a combination of disciplined cost management, pricing adjustments across the portfolio, and a revenue mix that has less reliance on lower margin CPE where memory cost pressure is the most acute. Consumer CPE represents a relatively small portion of our overall revenue. Although memory costs remain elevated and could deteriorate further, our current visibility supports gross margins in the near term, remaining broadly consistent with what we have delivered over the past several quarters. We entered the second quarter with a positive demand outlook. Fiber infrastructure investment remains active across our core business, and we continue to advance our initiatives in AI infrastructure and enterprise networks, expanding our business opportunities. Our priorities remain consistent, expanding operating margin, generating cash, and converting the strong customer pipeline into revenue. With that, I'll turn the call over to Tim to review our financial results in more detail. Tim? Timothy Santo | Senior Vice President and Chief Financial Officer: Thank you, Tom, and thank you all for joining us today. We delivered solid results for Q1 2026 led by continued and consistent execution. We had operating margin expansion to a new level despite a seasonal reduction in revenues that remained above the midpoint of our previously issued guidance driven by continued cost discipline and scale in the business. Our first quarter revenue was $286.1 million, up 15.5% year over year, and returning to a more normalized seasonal pattern. Geographically, U.S. revenue was $146.2 million, representing 51% of total revenue, up 42% year over year, and 7% sequentially. Non-US revenue was $139.9 million, or 49% of total revenue. Access and aggregation solutions revenue was $90.5 million, or approximately 32% of total revenue, up 2% year-over-year and 14% sequentially. Subscriber solutions revenue was $98.2 million, or 34% of total revenue, up 22% year-over-year. Optical networking solutions revenue was $97.3 million, or 34% of total revenue, up 24% year-over-year. Turning to gross margin, non-GAAP gross margin was 43%, up 55 basis points year-over-year from 42.5% in Q1 2025, and up 54 basis points sequentially from 42.5 in Q4 2025, driven by favorable product mix and continued progress on cost efficiency. Non-GAAP operating expenses for the first quarter were $103.3 million compared to $95.5 million in Q1 2025 and $105.1 million in Q4 2025. The year-over-year increase largely resulted from the impact of foreign currency fluctuations on our European cost base which has had minimal impact on operating leverage due to natural hedging and continued investment in R&D and go-to-market activities. Non-GAAP operating income was $19.9 million or 6.9% of revenue. On a sequential basis, operating income increased from 18.8 million or 6.4% in Q4 2025. Year over year, non-GAAP operating margin expanded 300 basis points from 3.9% in Q1 2025, continuing the progression from 5.4% in Q3 2025 and 6.4% in Q4 2025. Non-GAAP tax expense in the first quarter was $4.4 million, reflecting an effective non-GAAP tax rate of 25.5%. Non-GAAP net income attributable to AdTran Holdings was $11 million, or 14 cents per diluted share, compared to 3 cents in Q1 2025. Turning to the balance sheet and cash flow, net working capital was $253.9 million at quarter end, compared to $259 million at December 31st, 2025. During the quarter, inventory was $209 million with days inventory outstanding of 110 days down four days sequentially. Trade accounts receivable were 215.5 million with DSO of 68 days up two days sequentially due to the timing of quarter end invoicing. Accounts payable was 170.6 million with days payable outstanding of 66 days which is flat sequentially. As revenue scales, our focus remains on improving working capital efficiency. Operating cash flow was $12.7 million for the quarter, and free cash flow was a negative $3.3 million, reflecting timing of cash receipts and higher purchases of inventory. We ended the quarter with $88.3 million in cash and cash equivalents, compared to $95.7 million at December 31, 2025. Turning to our outlook for the second quarter of 2026, we expect revenue to be between $283 and $303 million and non-GAAP operating margin within a range of 5% to 9%. This concludes our prepared remarks. Before turning the call over to Tom, I'd like to highlight that we will be participating at the B. Reilly Conference on May 20th. in Marina Del Rey and the Evercore Technology Media and Telecom Conference on June 2nd and 3rd in San Francisco. We look forward to seeing many of you there. And now I will turn the call back to Tom. Great. Tom Stanton | Chief Executive Officer and Chairman of the Board: Thanks very much, Tim. Kayla, at this time, we'd like to turn it over to people that may have some questions. Kayla | Conference Call Operator: Wonderful. At this time, I'd like to remind everyone, in order to ask a question, press star then the number one on your telephone keypad. Your first question comes from the line of Mike Genovese with Rosenblatt Securities. Your line is open. Mike Genovese | Analyst at Rosenblatt Securities: Thank you very much. Tom, I'd like to hear about the LightWave 800 more, you know, about basically the strategy of launching this product, you know, maybe bigger thoughts on getting into the data center and But more specifically, any timing or size or margin expectations for the new product that you could share would be helpful. Thank you. Tom Stanton | Chief Executive Officer and Chairman of the Board: Yeah. I'm going to shy a little bit away from pricing on the product, although there is a lot of IP in that product, and IP typically gains better gross margins. The reason I mentioned it in my remarks is the – market reaction to it has been fantastic. We've had some very large, very well-known customers that have been very encouraging for us to get the product out as quickly as possible. Unfortunately, there is a lot of work to be done and I would expect that to be sometime about a year from now before we really kind of hit production level type numbers. We did show we do have prototypes now. We did show operating models at the recent OFC. It is a real product. It does work. It's a matter of getting it finalized and then getting it to scale, which will take some time just because it's very, you know, it's a semiconductor-type product. Now, that is one of the products we have. We also have the Quattro, which will be coming out the end of this year, which is a 4x100 product. product versus the 8x100 product. It is also a very, very power-saving product. I think it's better than anything out there on the market today. The real thing about the 800, though, is it's ridiculously low power. I mean, it's, I think, one picojoule per bit, which is an industry first. And that's what's driven the excitement around it. Mike Genovese | Analyst at Rosenblatt Securities: Interesting. Now, when you say, you know, there's a lot of IP in it, I mean, is it Is it fair to say that it would not be significantly dilutive to company gross margins? Tom Stanton | Chief Executive Officer and Chairman of the Board: It will not be dilutive to company gross margins. Mike Genovese | Analyst at Rosenblatt Securities: Okay, that's good to hear. I guess maybe just something similar on any other new products. I mean, we saw something about an announcement of an AI edge platform I'd like to hear more about. And then if I go back to OFC, I also think there was an announcement at least where you were demoing 800 and 400 ZR. So is that a product that you have, ZR? And could you talk more about the AI sort of edge platform? Tom Stanton | Chief Executive Officer and Chairman of the Board: Yeah, the AI edge platform I think you're talking about is still an offshoot of Clarity. So I'm not sure if there's anything else out there that we've seen that we announced. I'm not telling you it couldn't happen. But all of our AI products are in the Clarity family. We have an edge product. that we are trialing right now and then we have the core product for network operations that we have been trialing for some time. I will tell you the feedback here also is fantastic. I just recently had a bunch of customers and we had 150 or so customers here in Huntsville and the feedback that they just overwhelmingly positive so. Good things there on the 800 on the 400 ZR. 400 ZR. We do have products coming out towards the end of this year, I think, for 400. And those are just ongoing pieces. The AI piece, now that I think about the AI piece, you may be talking about it on Ensemble, which is the product that we were highlighting that has started to implement authentic AI in its product line. Mike Genovese | Analyst at Rosenblatt Securities: Okay, great. Yeah, I just wanted to get an update on those new products. So I'll... I'll pass it along to others for other topics. Thank you. Kayla | Conference Call Operator: All right. And your next question comes from the line of Irvin Liu with Evercore. Your line is open. Irvin Liu | Analyst at Evercore: Hi. Thank you for the question. I also had a question related to AI infrastructure. As you target this opportunity, can you talk about any sort of R&D and go-to-market investments needed to serve this customer segment? Thank you. Tom Stanton | Chief Executive Officer and Chairman of the Board: There is some shifting that we'll be doing throughout the year where we make sure that we have the right R&D resources and sales resources to be able to do that. But all of that is within the current operating budget that we have today. So I don't think there's going to be any significant increase. We're kind of committed to and believe that we can grow the business fairly meaningful within the budgets that we have today. Once we get north of our targeted 10%, or excuse me, we said low single digits, but 10% operating income, then we'll take a look at that as well and make sure that we're investing in the right places. But right now, we don't see any problems. Irvin Liu | Analyst at Evercore: Got it. And then for my follow-up, you've been seeing strong demand in the regional service provider customer segment. So can you talk about any sort of momentum you're seeing as it relates to your suite of software products such as Mosaic One and IntelliFi? Just any color on upsell efforts and attach rates here would be helpful. Tom Stanton | Chief Executive Officer and Chairman of the Board: Yeah, we don't have those numbers broken out, but I will tell you the uptick on IntelliFi has been fantastic. Mosaic got a very good launch. We have probably close to 500 customers right now on Mosaic 1, and all of those are in different levels of subscription base, but IntelliFi is fantastic. doing really well. I think last time we reported on it, it was over 100 customers, and it's been a real highlight. So we don't have those numbers broken now. Hopefully next quarter I'll be able to talk about them. Irvin Liu | Analyst at Evercore: Got it. Thank you. Kayla | Conference Call Operator: And your next question comes from the line of George Nodder with Wolf Research. Your line is open. George Nodder | Analyst at Wolf Research: Hi, guys. Thanks very much for the question. You mentioned cloud revenue and your cloud business. Can you remind us what percentage of sales comes from cloud operators? Do you have a sense for that? Tom Stanton | Chief Executive Officer and Chairman of the Board: Yeah, we don't break that out. As you know, George, we don't break out specific customer segments like that. But just to give you some kind of – hyperscalers actually did really good in the fourth quarter. They were, as I mentioned – a real positive in the quarter, and we would expect that to continue on through this year. I mean, we've got a fairly good backlog with some of our hyperscaler customers right now that's building, so that's pretty much it. George Nodder | Analyst at Wolf Research: Got it. Okay. And I assume these are – can you just walk through maybe the product sets that you sell in there and just kind of get us where you're pointing on, you know, what is – what you're leading with with customers? Obviously, the LightWave product is going to come on, but – Is it optical? What pieces are you selling? Tom Stanton | Chief Executive Officer and Chairman of the Board: Yeah, the biggest piece is optical, and it's a lot of the momentum we're seeing right now is around our 100 ZR plug. George Nodder | Analyst at Wolf Research: Got it. Okay. I guess I would have assumed the 100 gig ZR plug was a little bit more of a telecom application rather than a cloud application. Tom Stanton | Chief Executive Officer and Chairman of the Board: As you know, maybe you do know, I think you do know, George, that we have a fairly large footprint. So when you look at large data center connectivity, not in the sweet spot. That's where the 400 and 800 will play more. In the smaller data center interconnectivity spot, which some of the hyperscalers have as an architecture, it plays very well. George Nodder | Analyst at Wolf Research: Okay, super. And then the other one I had was just on the LightWave 800. Obviously, laser datacom chips are really hard to come by in the industry. I hear what you say about, you know, the business ramping a year from now. I guess I'm just curious about, you know, where you guys are getting laser datacom chip supply. Is that difficult to come by? Is it easy to come by? Is there anything you can tell us about where you're sourcing those? Thanks a lot, guys. Tom Stanton | Chief Executive Officer and Chairman of the Board: They probably won't get into direct sourcing on that. We do have some partners that we're working with on this. They do know what the supply needs are right now. Right now, we see Now, you know, depending on how aggressive that launch is, we don't see any issues in being able to supply it as we launch it. Okay. Great. George Nodder | Analyst at Wolf Research: Okay. Thank you. Kayla | Conference Call Operator: And your next question comes from the line of Ryan Kuntz with the Needham & Company. Your line is open. Ryan Kuntz | Analyst at Needham & Company: Great. Thanks for the question. I wanted to ask about optical demand, kind of it that made me step it up to a higher level. You talked about MOFIN demand here. you know, can maybe characterize where you are, you know, where you see the biggest drivers specifically within Europe for your optical product lines and, you know, which products you're seeing the greatest success with in terms of demand. You just talked about 100ZR. I assume that's a big piece, but maybe any more color beyond that would be great. Thanks, Tom. Tom Stanton | Chief Executive Officer and Chairman of the Board: Yeah, I do think 100ZR also, I think that the, especially in Europe, I think that our 400 and 800 gig products are going to play very well in that upgrade path as well. The customer base that we're talking about is a customer base that you already know. It's ones that we've been doing business with for a very long period of time. And they're trying to situate their networks to be able to do more basically wholesale services. That customer base is active. And then there's one here in the U.S. that you're already aware of that's also making a lot of noise around it. Ryan Kuntz | Analyst at Needham & Company: And are you seeing within that, are you seeing a shift away from traditional chassis-based transponders over to ZR-pluggables in the telecom side as well? Tom Stanton | Chief Executive Officer and Chairman of the Board: It's a mix. That is dependent on the carrier size. And it also depends on whether or not they already have installed chassis. Where there's already an installed chassis there, they're going to upgrade that chassis. Where it's a footprint, even in footprint on some of the larger carriers, the operational ease that, you know, the current systems provide is actually very beneficial to them, but it's definitely a mix. Ryan Kuntz | Analyst at Needham & Company: Got it. And then maybe hitting the gross margin here, obviously great results on the quarter. Congrats. And you talked about a lower mix of consumer CPE within your subscriber solutions. Can you maybe, you know, is consumer CPE, would it approach half of that number or you think it's maybe less than half of your your total subscriber business? Tom Stanton | Chief Executive Officer and Chairman of the Board: Probably, to be fair, it's probably, I think it's definitely not less than a half, but it's not substantially more. And I think the reason that I was bringing it out is we have gotten feedback that customers were unclear about kind of how much the CPE margin problem is affecting us. And it does affect us. I mean, there's no doubt about it. But the impact is substantially less when you take a look at it in the overall perspective of the entire company. But it is north of 50% of just the subscriber segment. Ryan Kuntz | Analyst at Needham & Company: Makes sense. And maybe one last one, if I can squeeze it in. You talked about some better visibility on bead projects here. What sort of milestones... should we look for before we start to see, you know, your revenues start to inflect for Bede? Are we talking about, you know, permits and design and, you know, forecasts and orders? Can you walk us through how we should think about, you know, the milestones that let Bede unfold and start to contribute for Atran? Tom Stanton | Chief Executive Officer and Chairman of the Board: Yeah, so funding is starting to flow or could flow for Bede. by far the majority of the states now. So a lot of that has been worked itself through. Now what you're seeing is kind of individual customers deciding how they want to roll out. We have some customers that have already placed purchase orders and they're rolling out or at least making sure that they've got supply to be able to not be a hamstrung. The smaller the customer, the easier that is. On the larger customers, you know, the biggest pull, long pull is going to be actually deploying the fiber itself, which is why, you know, we've been saying end of this year is probably where you start seeing that. On a local level, I mean, you can look at permitting and kind of where that is, it's kind of hard to actually get a good grasp of. At the end of the day, I'm looking for purchase orders. We're starting to see some today, but it's a trickle. It's not a lot, but we expect that. I mean, this whole unlocking of, the approval process really has accelerated. We went from maybe two states a quarter ago, I think three states a quarter ago, to pretty much all of the states now being able to send out funding. So I think the best visibility is actually seen in the numbers, though, because every carrier is going to be a little different. Ryan Kuntz | Analyst at Needham & Company: And you think you'll just see nice steady improvements and 27 starts to feel like a more material number for you. Tom Stanton | Chief Executive Officer and Chairman of the Board: Oh, absolutely. Ryan Kuntz | Analyst at Needham & Company: Yes, yes. Great. Irvin Liu | Analyst at Evercore: Thanks, Tom. Kayla | Conference Call Operator: Okay. And your next question comes from the line of Christian Schwab with Greg Helm. Your line is open. Christian Schwab | Analyst at Greg Helm: Oh, great. Thanks. Just a quick clarity on that, Tom. With 27 orders picking up in bead more materially, would you anticipate 28 being Potential peak revenue for that program, or do you think it extends beyond that? And would you be willing to quantify a revenue range of opportunity? You know, over a multi year timeframe that this program could offer you guys. Tom Stanton | Chief Executive Officer and Chairman of the Board: I think we've given a range before and, you know, that math changes depending on. Ultimately, which carrier actually is deploying where. Tim, do you remember what that range was? Timothy Santo | Senior Vice President and Chief Financial Officer: We had said of that market size, there was about a billion to go to the industry over multi-years. Tom Stanton | Chief Executive Officer and Chairman of the Board: So it's a five-year program. The timing of this, we've seen programs like this in the past. I think if you pick the middle of the window... That's typically where you see the majority of the spend. And then you'll see some kind of cleanup at the very tail end when people try to make sure that they get all the funding they can get. So, you know, my guess would be the middle of the program, which would be probably towards the tail end of 27. And then you'll probably see some cleanup from that point forward. And as you get towards the end of the program, you'll typically see some kind of flush as people try to make sure they get all the work they need to do. Christian Schwab | Analyst at Greg Helm: Great. That's great clarity. And then my last question just has, you know, your largest, one of your competitors, you know, spent a significant amount of time on their conference call talking about memory cost headwinds. I'm just wondering how you guys are navigating through that. Tom Stanton | Chief Executive Officer and Chairman of the Board: Yeah, sure. Right now we're doing good. So I do think that we are helped by the fact that we have a fairly diverse product portfolio. When you get into some of our larger products, like some of our larger access and ag platforms which handle thousands of customers, or you get into optical for that matter, the memory content on those products is just less of the total bill of material. so the impact is significantly less if you get into some of the lower end residential cpe that memory income that memory can be a large percentage of the total bill material and i think that's the direct impact if you take a look at our that maybe that's the direct tie through to your question if you take a look at our cpe for residential which is the most materially impacted is also the lowest cost products we sell and the lowest inherent gross margins to begin with that we sell. There's a bigger impact. When you get to some of the larger 100-gigabit platforms, 400-gigabit platforms, that memory impact is just substantially less, and I think that's the difference. Christian Schwab | Analyst at Greg Helm: Fantastic. Thanks, Tom. Okay. Kayla | Conference Call Operator: And your next question comes from the line of Dave Kang with B. Riley. Your line is open. Dave Kang | Analyst at B. Riley: Yes. Good morning. Just the first question is regarding the Middle East conflict. Just wondering if you can talk about the impact from that. Tom Stanton | Chief Executive Officer and Chairman of the Board: Yeah, so I think it impacts us in a couple of different ways. One is, without a doubt, it hurt us on the freight line. There are some, you know, some disruptions. Our freight expense this quarter was higher than I would like it to be. Probably be higher this quarter as well. So last quarter and this quarter. And that's just a matter of being able to get capacity in the right lanes. And it's a little messy last quarter, frankly. I think that's the biggest headline impact. We absolutely saw an impact, though, in our Middle East revenues as well. Some of that was disrupted last quarter. I don't know when that gets better. I would expect it to be a little better this quarter, but I think it hurt us both on the revenue and the cost line. Dave Kang | Analyst at B. Riley: Are we talking like maybe 1%, 2% revenue impact? Tom Stanton | Chief Executive Officer and Chairman of the Board: Revenue, yeah, less than 5%, yes. Dave Kang | Analyst at B. Riley: So it's definitely meaningful. I mean, material, right? Tom Stanton | Chief Executive Officer and Chairman of the Board: Well, especially if you talk on a regional, we look at EMEA as one big bucket, and that's how we manage it. And for the EMEA area, yeah, it definitely hurt. But on the overall company, it was fantastic. It was not as meaningful. I think on the freight side, it probably hurt more, to be honest with you. Dave Kang | Analyst at B. Riley: And should we expect that to be better this quarter? Tom Stanton | Chief Executive Officer and Chairman of the Board: I don't think our freight, yeah, I don't want to tell our operations guys, but I don't expect our freight to be materially better this quarter. I think it's going to be messy this quarter as well. Dave Kang | Analyst at B. Riley: I can't project. Go ahead. Yes. Got it. So that leads me to my second question is your operator margin guide for 5% to 9%. Just wondering if you can go over some of your assumptions of 5% versus 9%. Yeah. Tom Stanton | Chief Executive Officer and Chairman of the Board: Yeah. So we continue to think that, I mean, if you think about it, basically, we're assuming a similar freight environment in this quarter as last quarter and a similar memory impact in this quarter as last quarter. Dave Kang | Analyst at B. Riley: Got it. And then my last question is, were you able to raise prices or any plans to raise prices to counter, you know, elevated freight as well as component costs? Tom Stanton | Chief Executive Officer and Chairman of the Board: Freight, we're not pushing so much on. I mean, we're still very hopeful that that's transitory. Component prices on the memory prices, we have raised prices to customers to reflect the current challenges in that supply chain. Dave Kang | Analyst at B. Riley: Got it. Thank you. Kayla | Conference Call Operator: And once again, if you'd like to ask a question, please press stars and the number one on your telephone keypad. Your next question comes from the line of Tim Savageau with Northland Capital Markets. Your line is open. Tim Savageau | Analyst at Northland Capital Markets: Hey, good morning. I want to come back to a comment you made about optical, mainly kind of building throughout the year, which makes sense. Now, typically... In access and aggregation, you see kind of the opposite pattern, which is a stronger first half driven by Europe and then maybe a weaker second half. My question is, I wonder if Bede can serve to offset that this year so you might be able to have a similar type profile building throughout the year. Tim Savageau | Analyst at Northland Capital Markets: At least let's just focus on access and aggregation here. As a result of that, And at this point, are you able to make an estimate for what the annual incremental contribution of BID might be in the second half or this year in general? Tom Stanton | Chief Executive Officer and Chairman of the Board: Thanks. I really, yeah. Unfortunately, I really can't give an estimate on BID because there's too many customers and too many unknowns. But your question is, do I think it would offset the typical access in ag? I think a couple of things will play into that. Bede definitely will be helpful. I think the other thing that we expect to see, and this is still relatively early in the year, But I think Europe is going to be stronger than what we saw the last couple of years seasonally. So I think that you won't see the current expectations is that we won't see the same kind of fall off in the second half versus first half that we saw last year. Does that answer your question, Tim? Sure does. Thanks very much. Okay. Kayla | Conference Call Operator: And your next question comes from the line of Bill DeZellum with Titan Capital. Your line is open. Bill DeZellum | Analyst at Titan Capital: Thank you. Relative to the LightWave 800 and your engineering knowledge set that you have gained to reduce that power consumption by 90%, is there a carryover or an opportunity to take that knowledge and apply to other products throughout your catalog that could be materially impactful to the business? And if so, what's the timeline that it would take to have that technology or those capabilities infiltrate the rest of the product line? Tom Stanton | Chief Executive Officer and Chairman of the Board: I think it's relatively unique to the product sets that we're talking about. because of particular speeds and particular distances, that we're able to actually get the power savings that we're talking about. But I did call it a family. And I consider Quattro to be part of that same family, which is in our multi-mux family, which is very, very power savings as well. But I think the proliferation you'll see of that technology is in that pluggable space. So you're going to see first product is QSFP. We do have other products that are, let's say, I'll just say more integrated that will be coming out over time. So I think you're going to see different members of the family and similar application sets where this technology will actually play itself out. Bill DeZellum | Analyst at Titan Capital: And Tom, those applications are all within the data center or are there other short distance opportunities that are outside of the data center that I'm not thinking about right now? Tom Stanton | Chief Executive Officer and Chairman of the Board: There could be, but I can tell you that the demand inside the data center is worth focusing on. It is very large. Bill DeZellum | Analyst at Titan Capital: Great. That's helpful. Thank you. Okay. Tom Stanton | Chief Executive Officer and Chairman of the Board: At this, I think we are out of questions, so I want to thank everybody for joining us on the conference call and we look forward to talking to you next quarter. Thanks everyone. jsPDF 3.0.3 D:20260608224349-00'00'

Research summary and source transcript

readyJun 10, 2026

ADTRAN delivered strong Q4 and full-year 2025 results with double-digit revenue growth across all three business categories, driven by optical networking strength from cloud providers and enterprise customers, continued fiber access investment, and residential fiber CPE demand. The company achieved positive non-GAAP operating margin for the first time since 2024, improved cash flow generation, and strengthened its balance sheet through convertible note issuance and share repurchases reducing minority interest below 30%. While momentum appears sustained, the lack of full-year 2026 guidance and reliance on sequential growth trends leave near-term visibility limited.

Management knows today that the enterprise and cloud provider contribution to revenue reached 25% in Q4 2025 (up from 21% for the full year), driven by optical networking sales tied to data center capacity expansion and enterprise network upgrades—a trend they explicitly linked to AI-driven automation demands. This shift in customer mix toward higher-value, automation-integrated optical solutions is not yet reflected in market expectations, which still view ADTRAN primarily as a legacy access and aggregation provider. The market likely will not recognize this structural shift in revenue quality and margin potential for 6-24 months, as it requires sustained execution and clearer separation of AI-related optical sales in reporting.

Revenue growth driven by optical networking demand from cloud providers and enterprise customers, fiber access investment by U.S. and European operators, and residential fiber CPE demand from subscriber solutions; margin expansion fueled by scale efficiencies, product mix shift toward higher-margin optical and software, and disciplined cost management.

  • Optical networking growth from cloud providers and enterprise customers
  • Continued fiber access investment in U.S. and Europe
  • Residential fiber CPE demand and subscriber solutions
  • Software platform adoption including Mosaic One and IntelliFi
  • Balance sheet strengthening via convertible notes and share repurchases
  • Operating margin expansion and cash flow generation
  • Enterprise and cloud provider contribution to revenue reached 25% in Q4 2025, up from 21% for the full year
  • Agentic AI platform (Mosaic One Clarity) with numerous customer trials underway ahead of official launch later in 2026
  • Bead (Broadband Equity, Access, and Deployment) program funding beginning to flow in states like Louisiana, signaling future fiber deployment certainty
  • EU-driven Huawei replacement opportunity viewed as a 'near billion dollar a year' potential market
  • Strong momentum in enterprise optical, including ICP carriers, tied to AI-driven bandwidth needs

Management exhibited a consistently upbeat and confident tone, emphasizing sustained momentum, strong execution, and improving financial metrics without defensiveness. They provided specific, evidence-backed details on customer trends (e.g., bead funding flowing in Louisiana, enterprise optical mix shift), acknowledged operational challenges (e.g., uneven European telco spending), and clarified strategic nuances (e.g., distinguishing carrier vs. enterprise optical revenue, explaining why leasebacks were not pursued). Their willingness to discuss both progress and unresolved issues (e.g., non-core asset timing, Huawei replacement timeline) enhanced credibility, avoiding overpromising while reinforcing conviction in underlying trends.

  • No clear dodged analyst question was detected by the local fallback; manual review should still check whether Q&A answers quantified conversion, margins, and guidance.
  • There may be a benchmark or metric-framing issue worth manual review, especially around adjusted metrics, timelines, or changed expectations.

ADTRAN appears to be gaining competitive share, particularly in optical networking where they are winning enterprise and cloud provider business tied to data center and AI-driven upgrades, and in Europe where they are benefiting from Huawei replacement momentum and vendor diversification. Their software platform adoption (Mosaic One, IntelliFi) is increasing customer stickiness and expanding TAM beyond hardware. While they face competition in access and aggregation, their integrated optical-software approach positions them favorably in the evolving intelligent fiber network market. Overall, the company is strengthening its competitive position in key growth segments.

  • Q4 2025 revenue: $291.6 million, up 20% year-over-year and 4% sequentially
  • Optical networking revenue: grew 33% year-over-year, driven by cloud providers and enterprise customers
  • Enterprise and cloud provider contribution to revenue: 25% in Q4 2025, 21% for full year 2025
  • Non-GAAP gross margin: 42.5% in Q4 2025, up 122 basis points year-over-year
  • Non-GAAP operating profit: $18.8 million (6.4% of revenue) in Q4 2025, up 406 basis points year-over-year
  • Full-year 2025 revenue: $1.084 billion, up 17.5% year-over-year
  • Full-year 2025 non-GAAP operating margin: 4.8%, up from negative 0.3% in 2024
  • Full-year 2025 operating cash flow: $129.8 million, up 25% year-over-year
  • Continued expansion of enterprise and cloud provider optical sales, particularly tied to data center and AI infrastructure
  • Official launch of agentic AI platform (Mosaic One Clarity) expected later in 2026
  • Sustained bead funding deployment enabling more predictable fiber build-out cycles
  • Accelerating Huawei replacement in Europe due to national-level mandates and vendor diversification
  • Growing adoption of software platforms (Mosaic One, IntelliFi) automating optical and subscriber networks
  • Reliance on sequential growth trends without full-year 2026 guidance creates near-term visibility risk
  • Optical growth dependent on cloud provider and enterprise spending, which could soften if AI infrastructure investment delays
  • European revenue subject to uneven timing from tier-one carrier front-loaded deployment patterns
  • Working capital pressure from rising DSO (up to 66 days) despite inventory improvements
  • Memory and optics supply chain tightening could impact gross margin stability despite management's downplay
  • Non-core asset sales (e.g., buildings) remain unresolved and contingent on market conditions
  • Minority interest reduction dependent on continued share repurchases, which use cash that could fund growth

Management directly linked optical networking growth to cloud providers expanding data center capacity and enterprises upgrading optical networks, explicitly stating this reinforces a trend of 'cloud providers expanding data center capacity' and 'large enterprises upgrading their optical networks.' They further tied this to AI-driven automation, noting that service providers, cloud providers, and enterprises are pairing high-capacity fiber networks with automation and software to streamline operations, and that their agentic AI platform (Mosaic One Clarity) is an 'important addition' to software capabilities as demand for AI-driven automation grows. This indicates a clear, near-term impact from data center and AI-related optical demand, not merely speculative.

  • What portion of Q4 optical networking growth came specifically from AI/data center-related cloud provider deployments versus traditional enterprise or carrier use cases?
  • When will the company begin reporting enterprise and cloud provider optical revenue as a separate line item to improve transparency on this high-growth segment?
  • How sustainable is the 25% Q4 enterprise/cloud provider revenue contribution, and what are the renewal or expansion rates among these customers?
  • What is the expected timeline and revenue contribution from the official launch of the Mosaic One Clarity agentic AI platform later in 2026?
  • To what extent are bead (Broadband Equity, Access, and Deployment) funds translating into actual equipment orders, and what is the expected lag between funding announcement and revenue recognition?
  • How is the company addressing the working capital drag from rising DSO, and what specific initiatives are in place to improve cash conversion as revenue scales?
  • What is the expected impact of memory and optics supply constraints on gross margin in 2026, and what hedging or contractual protections are in place?
  • What percentage of the European optical opportunity is tied to Huawei replacement versus general network modernization, and what is the win rate in Tier 1 carrier bids?

NASDAQ:ADTN Q4 2025 Earnings Call Transcript Generated on 6/8/2026 Julianne | Conference Operator: Good morning, my name is Julianne and I will be your conference operator. At this time, I would like to welcome everyone to ADTRAN Holdings' fourth quarter and full year 2025 financial results conference call. All participants are in a listen-only mode. After the speaker's remarks, we will conduct a question and answer session. To ask a question at this time, you'll need to press star followed by the number one on your telephone keypad. Thank you, Mr. Peter Shuman, Vice President, Investor Relations, you may begin your conference. Peter Shuman | Vice President, Investor Relations: Thank you, Julianne. Welcome and thank you for joining us today, and welcome to all those joining by webcast. During the conference call, ADTRAN representatives will make forward-looking statements that reflect management's best judgment based on factors currently known. However, these statements involve risk and uncertainties, including those detailed in our earnings release, our annual report on Form 10-K as amended, and our other filings with the SEC. These risks and uncertainties could cause actual results to differ materially from those in our forward-looking statements which may be made during the call. We undertake no obligation to update any statements to reflect events that occur after this call. During today's call, we will refer to certain non-GAAP financial measures, reconciliation of GAAP to non-GAAP measures, and certain additional information are also included in our investor presentation and our earnings release. We have not provided reconciliations of our first quarter 2020 outlook with regard to non-GAAP operating margins because we cannot predict and quantify without unreasonable effort all of the adjustments that may occur during the period. The investor presentation has been updated and is available for download on the AdTran investor relations website. Turning to the agenda, Tom Stanton, AdTran holding CEO and chairman of the board, will provide key highlights for the fourth quarter and full year 2025. Tim Stanto, our senior vice president and CFO, We'll review the quarterly and full-year financial performance in detail and provide our first quarter 2026 outlook, and then we will take questions that you may have. I would now like to turn the call over to Tom Stanton. Tim Stanto | Senior Vice President and CFO: Operator, we are receiving notification that the line is bad and that recipients are not hearing us correctly. Is there a way to approve the line before we proceed? Julianne | Conference Operator: You're having it loud and clear from my end. Tom Stanton | CEO and Chairman of the Board: Thank you very much. Thanks, Peter, and good morning, everyone. AdTrend delivered a strong fourth quarter and finished 2025 with... ...continued to improve and earnings came in above expectations with all three business categories achieving sequential and year-over-year growth. In the fourth quarter, AdTrans generated revenue of $291.6 million, reflecting a strong year-over-year growth of 20% and sequential growth of over 4%. This marked the sixth consecutive quarter of sequential growth and the fifth consecutive quarter of year-over-year improvement, reinforcing the strength of our company and our key markets. Our U.S. business led to quarterly growth with revenue up 31% year-over-year and 14% sequentially. Non-US revenue grew 12% year-over-year and declined 3% sequentially, as expected and consistent with recent ordering patterns among some of our larger European customers. Optical networking solutions grew 33% year-over-year, driven by strong sales to cloud providers and enterprise customers. This increase also drove the contribution of enterprise and cloud providers to 25% of our revenue in Q4 and 21% for the full year of 2025. These results reinforce a trend we are seeing, cloud providers expanding data center capacity and large enterprises upgrading their optical networks. During the quarter, we continue to broaden our optical customer base. We saw solid activity across service providers, cloud providers, enterprises, and public networks, reflecting the flexibility of our optical platforms across different use cases. Access and aggregation revenue grew 9% year-over-year and 6% sequentially, supported by continued fiber access investment across U.S. and European operators. During the quarter, customer activity reflected a mix of expansion projects and network upgrades as operators advanced deployments. In subscriber solutions, revenue grew 17% year-over-year and 3% sequentially, driven by demand for our residential fiber CPE as customers continue to connect more subscribers. The revenue in this category continues to be generated by a diverse mix of residential, enterprise, and wholesale service offerings. Today, our software solutions serve over 1,000 carrier customers across three of our product categories, automating everything from optical networks to in-home subscribers' experiences. These customers include nearly 500 service providers adopting our Mosaic One platform and more than 100 service providers deploying our recently introduced IntelliFi cloud managed Wi-Fi solutions. We are also advancing our agentic AI platform with numerous Mosaic One Clarity customer trials underway before an official launch later this year. As demand for AI driven automation grows, we see this application suite as an important addition to our software capabilities. Looking at the broader environment, we continue to see sustained fiber investment across our core markets. And the U.S. broadband programs and ongoing investments in data centers are supporting ongoing network expansion. In Europe, increased focus on network security and vendor diversification away from higher-risk suppliers is reinforcing upgrade activity across the region. These trends are supporting continued demand for upgrades across all three product categories. At the same time, network requirements continue to evolve. across data centers, between the data center, and out to the customer edge. Capacity demands are increasing. Service providers, cloud providers, and enterprises are pairing high capacity fiber networks with automation and software to streamline operations. While this is still an emergency contributor to our revenue, it reinforces the market's longer term direction towards more intelligence and more automation. With our broadband fiber network portfolio, software assets, and regional strength, we are well positioned to support both the current infrastructure cycle and the longer-term evolution towards these more intelligent fiber networks. We delivered a strong Q4 with solid financial results in execution and healthy core and healthy cash flows. For the full year of 2025, we delivered double-digit revenue growth with each of our three revenue categories also growing at double-digit rates. We achieved this while expanding gross margins and returning to positive non-GAAP operating margin, NAPS. Also during the year, we strengthened our balance sheet by issuing approximately 200 million of convertible notes at an interest rate meaningfully lower than our revolving credit facility. We were able to purchase 27.2 million of AdTran network shares during Q4 and 46.6 million worth of shares during the calendar 2025, reducing the minority interest to less than 30% as we close the year. As we move into 2026, our priorities remain continued improvement in our leverage model, expanding operating margin, cash generation, and converting the customer momentum that we have been seeing. We continue to operate in our dynamic cost environment, including variability in components such as memory. We are managing that variability through discipline procurement and price mechanisms that are already embedded in our model. At this time, we are not seeing conditions that change our demand outlook or execution priorities. In summary, we entered 2026 with a positive outlook. Customer trends are favorable in the U.S. and Europe. Customer acceptance of products has been strong, and our product offerings and competitive position has never been better. We have several multi-year tailwinds in our key market segments. With that, I'll turn the call over for Tim to review the financial results in more detail. Tim Stanto | Senior Vice President and CFO: Thank you, Tom, and thank you all for joining us this morning. We delivered strong results for the fourth quarter and full year 2025, driven by solid execution and healthy revenue growth. As scale improved, we delivered higher margins and operating efficiency increased across the business. We remain focused on disciplined cost management as we continue to grow. Over the quarter, we continued to operate with tight financial processes and consistent execution. These remain embedded in how we run the business, improving visibility and planning rigors and supporting structured capital allocation. While the mix between gross margin and operating expenses can shift from quarter to quarter as revenue moves, our objective remains focused on steady margin expansion as the business scales. As we noted on our previous earnings call, the capital actions we took last year improved our financial flexibility and added optionality. Broadly, our focus remains on simplifying the capital structure and maintaining flexibility to support the business and create value. We will continue to deploy cash thoughtfully to reduce the minority interest over time while maintaining balance sheet strength and evaluating non-core asset monetization opportunities as appropriate. Turning to the financial results for the fourth quarter of 2025. Revenue was 291.6 million, up 20% year-over-year and 4% sequentially, above the high end of our original guidance. Year-over-year growth was driven by all three product categories, with optical networking the largest and fastest contributor, with revenue increasing by 26.9 million, or 33% from the prior year. Geographically, Non-U.S. revenue accounted for 53% of total revenue, while U.S. revenue accounted for 47%. Non-GAAP gross margin increased to 42.5%, up 44 basis points sequentially and 122 basis points year-over-year, driven by scale efficiencies, product mix, and cost disciplines. We remain focused on sustaining gross margin in the 42% to 43% range over the long term. Non-GAAP operating profits rose to $18.8 million, or 6.4% of revenue, exceeding the midpoint of our original outlook and up 103 basis points sequentially and 406 basis points year over year. Non-GAAP tax expense in Q4 2025 was $3.8 million or an effective rate of 22.6%. Non-GAAP EPS was 16 cents compared to 5 cents in Q3 2025 and a loss of 2 cents a year ago. EPS benefited by 3 cents from the acquisition of shares from minority holders in the fourth quarter. We continued to strengthen our financial position during the year. Year over year, net working capital improved by $8.7 million due to meaningful inventory reductions, largely offset by increases in accounts receivable due to increased sales. During the year, inventory declined by almost 50 million, including 8 million during the fourth quarter. Days inventory outstanding improved by 47 days year over year, and 10 days in the fourth quarter to 114. DSO increased to 66 days, down by one day year over year, and up seven days sequentially due to increased sales and the timing of Q4 invoicing. As revenue scales, our focus remains on improving working capital efficiency. Operating cash flow was 42.2 million for the quarter, and free cash flow was 22.5 million For the full year, we generated $129.8 million in operating cash flow and $60.5 million in free cash flow, representing healthy increases of 25% and 58%, respectively, compared to 2024. We ended Q4 with $95.7 million in cash and cash equivalents after purchasing $27.2 million or 1.2 million shares of AdTrend Network stock. For calendar year 2025, we purchased $46.6 million, or 2 million shares, of AdTrend Network stock and now own just over 70%. And meaningfully reduced the interest rate on our outstanding debt as a result of the convertible note offering. Turning to our operational performance for the year, we made meaningful progress across key financial metrics during 2025. Revenue increased 17.5% year-over-year, totaling $1,084,000,000. We expanded full-year non-GAAP gross margin by approximately 90 basis points to 42.1%, reflecting increased scale, higher efficiency, and favorable product mix. Non-GAAP operating margin increased to 4.8% in 2025 from negative 0.3% in 2024. And non-GAAP diluted EPS returned to a positive 23 cents per share. We delivered a strong year of cash flow generation with net cash provided by operating activities increasing by 26.2 million to 129.8 million. We remain disciplined on cost structure while positioning the company to convert revenue into sustained earnings growth. Looking ahead at our outlook for the first quarter of 26, we expect revenue to be between $275 million and $295 million and non-GAAP operating margin of 4% to 8%, reflecting traditional seasonality and current supply chain dynamics. I will now turn the call back over to Tom. Tom Stanton | CEO and Chairman of the Board: All right. Thanks very much, Tim. Julianna, I think at this point we're ready to open it up for any questions people may have. Julianne | Conference Operator: Thank you. We will now begin the Q&A session. As a reminder, to ask a question, please press star followed by the number one on your telephone keypad. Our first question comes from Michael Genovese from Rosenblatt Securities. Please go ahead. Your line is open. Michael Genovese | Analyst, Rosenblatt Securities: Great. Thanks. You know, a great conference call, you know, clearly upbeat messaging. Tom, can you just talk a little bit more, I guess, specifically about the demand picture in U.S. and Europe and sort of what you're seeing from your clients on the optical side and on the fiber to the home side, and just talk a little bit more about the drivers of the revenue growth and Um, I guess related to that, like, you know, do you think, obviously you're not giving full year revenue guidance, but, you know, coming off a year where you grew 20%, um, you know, do you think double digit growth is, uh, is top line growth is in the cards for, for, for 26? Yeah. Tom Stanton | CEO and Chairman of the Board: So let me, let me start one a little down, which is, you know, we don't give full year guidance for a reason. And that's because our outlook is, you know, typically are still our, our book to ship, um, period is relatively small, so it's a little difficult. Let me speak a little bit more about the kind of the environment that we're in right now. I would say it's kind of the same tone and kind of building momentum that we saw throughout last year, and we expected that to continue on, and that's exactly what's happening. So we, on the fiber to the prem side, nothing has slowed down. Programs are still going well. We're still adding new customers to those product areas, and we're continuing to operationalize carriers in Europe. So all of that is just a continuation of the same type of activity we saw last year. On the fiber front, the dynamic is a little bit different because we were still at the very beginning of the year, kind of crawling out of the revenue inventory uptake that we had seen in our customer base. That cleared itself up last year. We started seeing that real progress in the second half of the year. We also, you know, as you may be aware, that it won some additional customers both here in the U.S. with wider scale kind of Tier 2 deployments as well as in Europe where we won some Tier 1s, and that momentum is just continuing on. I would say, you know, that is driven not just by the Huawei replacement, which is going on in Europe, but just in general. I just think activity we just saw. customers starting to unleash capital and trying to increase their bandwidth for obvious reasons. I mean, I think all of them are trying to figure out how they're going to play in a new AI-driven world. I think MoFi is a driver. We definitely, I mentioned it on the call, we saw some real positive momentum on the enterprise side, which includes ICP carriers, right? So, yeah, it's just generally a good environment. Michael Genovese | Analyst, Rosenblatt Securities: Great. And then my second and last question will just be on pretty wide operating margin outlook of 48% for the quarter. So is that because of things like memory prices that the range is that wide, or is that kind of maybe more of a normal range, and I'm just reading it as being wide? Tom Stanton | CEO and Chairman of the Board: To us, I don't think there's any difference in the range that we get than what we typically do. There is tightening supply, as everybody is aware of, on memory. There's some tightening supply on optics. But I would say that that's not overly impacting the guidance range. Our kind of operating model is still what we fully expect it to be, what we've communicated, which is operating expenses in the low 100 range and gross margins in the 42, 43 range. I don't see we see a deviation from that. Tim, any comments? Tim Stanto | Senior Vice President and CFO: No, I would reiterate, as Tom said, the guidance range is about four points, which if you look historically is where we've been, and it's actually up a little bit from last quarter. But, you know, the leverage model would remain up from what we guided last quarter. You mean midpoint? Michael Genovese | Analyst, Rosenblatt Securities: Yeah. Perfect. I'll pass it on. Thanks so much. Okay. Julianne | Conference Operator: Our next question comes from Ryan Kuntz from Needham & Company. Please go ahead. Your line is open. Ryan Kuntz | Analyst, Needham & Company: Great, can you hear me okay? Julianne | Conference Operator: Yeah. Ryan Kuntz | Analyst, Needham & Company: Super, hey guys. When asked about optical, maybe to unpack a little bit, and you talked about enterprise ICPs, I assume that's a big driver of optical. Do you have any ideas like how much of that is really hyperscale and AI data center cloud related versus what I would call traditional SP and enterprise networking? maybe help us understand some of those dynamics there within the optical strength? Tom Stanton | CEO and Chairman of the Board: Sure. So there was actually a good contribution on both of those fronts in the quarter. And I'm trying to think if it was, I would say, and this is not having the note in front of me, that the mix on traditional enterprise, including the banking sector and all of the larger enterprise that we play into is a portion of that. And then ICP did come in stronger in the quarter than what we had historically seen. And we expect that momentum to continue on through this year. Ryan Kuntz | Analyst, Needham & Company: Great. And I recall a conversation from OFC last year about this opportunity in MOFIN where the hyperscalers are contracting with traditional SPS or maybe some of the some of the tier twos like Colt, et cetera, to build for them. Are you seeing some benefit there as well, and would that show up in your SP business as opposed to your enterprise business if it was a Mofin-type deal? Tom Stanton | CEO and Chairman of the Board: No, that would show up in our carrier. We would consider that to be a carrier customer. We're definitely saying that. We talked about that in the last maybe couple of conference calls, how we were starting to see some of the carriers position themselves to be able to do Mofins. That's just a continuing ongoing kind of upgrade cyclical thing that's adding positive momentum to that business. So, but that is separate and apart from the enterprise piece that we're talking about. Ryan Kuntz | Analyst, Needham & Company: Great. And maybe just one last, if I could, on fiber to the home side, relative to new footprint, you know, it seems like the U.S. has been a little bit hit and miss where some segments do better than others. Any update there on how Q4 turned out in terms of new greenfield footprint and how you're thinking about 26 going forward for U.S. Fiber, the home of greenfield builds? Tom Stanton | CEO and Chairman of the Board: Yeah, I think it was, I'd call it a solid quarter, kind of consistent with what we had seen in the year. I'd mentioned that in general, the U.S. business was definitely stronger on a sequential and year-over-year basis. I think we're expecting good things this year. We finally, I probably shouldn't say the word, but bead dollars are actually starting to flow. We've got a customer in Louisiana that is expecting bead dollars hopefully next week. I don't want to over-rotate on that, guys, because the build-out is going to consistently be driven for most carriers by kind of fiber deployment for this year. and equipment next year. But the fact that that's actually flowing is real positive. I think there's six other states that expect money any day now. So the fact that those dollars are starting to flow, I think, is a positive thing. And it's just as positive, not just the B dollars, but from a planning perspective and knowing that it's going to happen and giving carriers surety as to how they plan their capital budgets is very important. Ryan Kuntz | Analyst, Needham & Company: Right. So the planning, engineering, and maybe the fiber optic cable spending this year from bead sees an earlier uptick, you're saying, than your equipment would see this year that would fall within quarter two behind? Tom Stanton | CEO and Chairman of the Board: Yeah, you've got to be able to deploy that fiber. But I think the positive thing for us, which we don't know how that will impact, and it may just be a kind of positive influence, is the fact that you get surety in your budget planning cycle for not just your bead funding, but your normal capital spend as well. And I think that that's been missing for some time. Ryan Kuntz | Analyst, Needham & Company: That's great, guys. Thanks for the commentary. Thanks, Tom. Julianne | Conference Operator: Our next question comes from Christian Schwab from Craig Hallam. Please go ahead. Your line is open. Christian Schwab | Analyst, Craig Hallam: Great execution in the quarter, guys. Tom, I know we're sitting here at the end of February, non-core asset sales and potential building sales and leaseback activity. Would you be disappointed if we didn't have resolution on both by the end of calendar 2026? Tom Stanton | CEO and Chairman of the Board: well uh leaseback activity more than likely that is not going to happen um with the north tower so excuse me the east tower so let me be clear on where we are with that i think we've been trying to talk about this now for a couple of quarters we did get several lease offers off the building financially it didn't make sense for us um because of where we are with our cast position right now and what we'd use for the cash and what that lease would ultimately cost us, so we have put that on hold. We can always revisit that if we want to. Then on the north-south tower, which is the thing that's up for sale, I'm going to let Tim jump in here and give you an update on that. Tim Stanto | Senior Vice President and CFO: A lot of activity in the Huntsville market. We're not currently under contract, but we have activity, so we continue to work that, and when the right deal comes along, we will close that. As we had hoped it would happen in 2025, we are very optimistic it will happen in 2026, but the market will dictate. Christian Schwab | Analyst, Craig Hallam: Great. Thank you. And then on the non-core asset side, Tom, do you think that can get resolved this year, or is that a fluid situation? Tom Stanton | CEO and Chairman of the Board: Yeah, so we're, we, let me try to do this in a proper way. We have taken a look at the non-core assets. We've gotten values on what we think the non-core assets that we think are not strategic, right, to our business. We are doing things right now that we think will increase the value of those assets and we'll reevaluate that in the second half of this year. Christian Schwab | Analyst, Craig Hallam: Perfect. And then my last question, as we go throughout calendar 2026, you know, is there one area, we spoke positively, obviously, about, you know, finally loosening up after many years of seeing some progress as feed is concerned. you know, as we look at, you know, equipment replacement in Europe, the strength in optical, you know, geographical strength in Europe, et cetera. Is there one thing more than another that you're most excited about as we go through 2026 that we can monitor? Tom Stanton | CEO and Chairman of the Board: Yeah, so I think Let me just hit on a couple. One is I think enterprise is doing really well. And as I mentioned earlier on the Q&A, there are multiple drivers for that. We expect that to be strong this year. And so that strength is above whatever the company is doing on a corporate average perspective. So that's really good to see. The other is there is some legislation going on. I don't know how much... success it's going to have. It's good that it's going on, but in the EU right now, to accelerate the Huawei replacement piece, it's not so much whether or not that actually happens, which there's a high likelihood it happens, but just the focus on that is positive for our business. I'll remind people, we think that's a near billion dollar a year type opportunity that Huawei is selling into the European market that we think we have a very good chance of being able to to be able to capitalize on. So as that pressure continues on, and it is, you know, if there was legislation that was sent out in the EU in early of last year, that is positive, right? So that addresses this issue. So, yeah, so I think both of those things are real positive catalysts. Christian Schwab | Analyst, Craig Hallam: Great. Thank you for the clarity. No other questions? Julianne | Conference Operator: Our next question comes from George Nodder from Wolf Research. Please go ahead. Your line is open. George Nodder | Analyst, Wolf Research: Hey, thanks a lot, guys. I guess I just want to keep going on the question of Huawei replacement in the EU. You know, I think the regulatory stance currently basically has it not compulsory to replace Huawei, but I guess suggested would be kind of the idea in terms of the current regulatory environment. I know the stuff that's coming down the pike is going to mandate Huawei replacement, and it sounds like it could be a few years away until that legislation actually requires companies to or carriers to replace Huawei. But I guess I'm just curious, like, what has the inflection happening right now? Is there something you're seeing with your customers that, you know, allows them to move more quickly? Is it funding? Is it, you know, more, you know, pressure from a political perspective? I guess I'm just trying to understand what's driving this. Thanks. Tom Stanton | CEO and Chairman of the Board: Yeah, sure. Yeah, I agree. Well, let me just make one caveat to that. Although the EU's directive is more of a recommendation, the country-by-country and carrier-by-carrier requirements or legislative actions are different, right? So we do have some countries in the EU that have explicitly been stronger on that. And it's not so much that I think that legislation and the talk of that legislation and the fact that we're even talking about it here is exactly the point, which is if you're a carrier and you're doing a new award, you're kind of crazy to be deploying Huawei at this point. Or if there's a new region, a new footprint that has to be built out, even if they're an approved vendor, you know you're going to have a problem. So what that's doing is putting on, increasing the breaking pressure on continuing to deploy them on an ongoing basis. I would agree that pulling them out is a different thing, and that will take years. And, you know, we've characterized that north of, and it's an easy math to our trees to do, right? It's a north of $10 billion opportunity for the pullout. But what we're talking about is just on the annual spend where they're going in and filling in new cards, building out new footprint. That kind of activity is going to continue to slow down. George Nodder | Analyst, Wolf Research: If I look at that $1 billion annual spend, how well positioned do you think you are On that, I mean, obviously that's across a number of product categories. It's across a large number of specific operators. Maybe some you're in, some you're not. I mean, is there a way to kind of pin down that $1 billion in annual spend in terms of what's like really reasonable for you? Tom Stanton | CEO and Chairman of the Board: Let me not be, yeah, please, let me not be so sloppy on that number. The last time we looked at it, and we do have another, we have an outside firm trying to take a look at exactly what that number is at this point. that number is derived from about an 800 i think it was 850 or 860 million dollar number for mia in our target product areas and that was in 24. um we think that that number is going to continue to slow down it was north of a billion dollars not that long ago so that number will continue to slow down as we actually pick up that market share now that's for products that are specifically in our product sweet spot which is kind of mid-mile, regional network optical, access and aggregation. It is those products that we're actually talking about. So it's really what we believe the TAM is for our products. But like I'm trying to say, it's a rough number right now, and it's just based off of the earnings results of Wiley. George Nodder | Analyst, Wolf Research: Thank you very much. Okay. Julianne | Conference Operator: Our last question comes from Dave Kang from B Riley. Please go ahead. Your line is open. Dave Kang | Analyst, B. Riley Securities: Thank you. Good morning. First, regarding European telcos, you talked about them being front-loaded. Just wondering if you can kind of quantify whether it's 55, 45, or is it more exaggerated? Tom Stanton | CEO and Chairman of the Board: I'm sorry. Your question broke up for me. Could you rephrase it or restate it? Dave Kang | Analyst, B. Riley Securities: Yeah. Regarding your European telcos, tier ones, in the previous call, you mentioned said they tend to be front-loaded. Just wondering if they're like 55, 45, or more like 60, 40, any color. Tom Stanton | CEO and Chairman of the Board: Oh, oh, oh, as far as in the year. Is that what you're talking about? Yeah. I don't know if I've seen that actual breakout. I would say it's definitely last year it was probably 60-ish, 40-ish, and this is just off the cuff. And this is predominantly in the... access and ag product category. So you'll see that last year. You could see that last year in our access and ag number. You actually saw that kind of big bump in the first half of the year and then it kind of tailed down. It's not as prominent in the rest of the product areas. They kind of, they're just not under the same cycle. Dave Kang | Analyst, B. Riley Securities: And are you kind of expecting similar dynamics this year or any changes from last year? Tom Stanton | CEO and Chairman of the Board: Really good question. I will tell you, we weren't happy with that bump because of what that does operationally. You know, bumpy is never as good as smooth. So we have been talking to them about that and trying to get that to be more even flowed this year. So I don't know how successful we've been with at this point. So hopefully you won't see that same type of kind of waterfall. Dave Kang | Analyst, B. Riley Securities: and my uh second question is uh regarding uh the same european telcos uh just uh where are we in terms of the you know their broadband deployment cycle are we in still early stages or mid or getting towards the late innings oh good well if you take europe as a whole there's no way to characterize it other than early you know we've um Tom Stanton | CEO and Chairman of the Board: brought just recently some new carriers on that haven't been deploying with us, and then they all kind of have this Huawei issue as well. If you take specific areas, there are countries that are farther along. The U.K. is, I would say, kind of more towards the middle. Germany is probably definitely within the first half. So it depends on the carrier. Some of them haven't started yet. Dave Kang | Analyst, B. Riley Securities: Got it. Thank you. Tom Stanton | CEO and Chairman of the Board: OK. At this point, I think we are no more questions in the queue, so I'd like to thank everybody for for the participation day and we look forward to talking to you next quarter. Julianne | Conference Operator: Ladies and gentlemen, that concludes today's call. Thank you for your participation. You may now log off. jsPDF 3.0.3 D:20260608224608-00'00'

Research summary and source transcript

readyJun 10, 2026

ADTRAN delivered solid Q3 2025 results with revenue near the upper end of guidance and improved operating margins, driven by double-digit year-over-year growth across all three business categories. The company strengthened its capital structure through a $201 million financing transaction that lowered borrowing costs and increased financial flexibility. Management highlighted momentum in optical networking (47% YoY growth) and subscriber solutions, while noting temporary timing shifts in access and aggregation due to two large European customers' buying patterns, with expectations of recovery in Q4 or early next year.

Management knows today that the two large European customers in the access and aggregation segment have shifted their buying patterns, causing a temporary offset in revenue that is expected to reverse in Q4 2025 or early 2026, which the market may not fully appreciate as a transient issue rather than a structural decline. This insight comes from Tom Stanton's explicit confirmation of a 'push out' in timing due to differing budget cycles and calendar offsets, which he frames as normal 'puts and takes' rather than risk, suggesting the market may overreact to the near-term weakness without recognizing the anticipated recovery.

Revenue growth across optical networking, access and aggregation, and subscriber solutions; operating leverage from scale efficiencies; and financial flexibility from strengthened balance sheet and reduced borrowing costs.

  • Optical networking growth and new customer wins in Europe
  • Timing shifts in access and aggregation due to two large European customers
  • Capital structure improvement via $201 million financing transaction
  • Progress on monetizing non-core assets (Huntsville campus sale)
  • Mosaic One AI platform and early customer pilot results
  • Expectations for operating margin expansion in 2026
  • Optical networking grew 47% year over year and 15% sequentially, driven by strong momentum in Europe and a new large service provider
  • Added 15 new optical customers in the quarter, reflecting continued share gains
  • Mosaic One Clarity AI application showing up to 75% reduction in network-related trouble tickets in customer pilots
  • Non-GAAP operating profit rose to $15.1 million (5.4% of revenue), exceeding midpoint of outlook and up 89% sequentially
  • Expects to see orders for bead spending environment in first half of calendar 2026

Management exhibited a direct and credible tone, providing specific explanations for variability (e.g., European customer timing shifts) without evasion, acknowledging both strengths and near-term headwinds. They backed optimism with concrete metrics (e.g., 47% optical growth, 75% trouble ticket reduction in AI pilots) and clarified long-term goals (e.g., 43% gross margin target) without overpromising. CFO Tim Santo delivered precise financial details with clarity, and CEO Tom Stanton avoided vague assertions, instead grounding statements in observable trends like customer wins and pilot results. There was no defensiveness or excessive promotional language; instead, the tone was measured, transparent, and focused on executable progress.

  • There may be at least one Q&A answer that needs manual review for a possible dodge or lack of numerical follow-through.
  • There may be a benchmark or metric-framing issue worth manual review, especially around adjusted metrics, timelines, or changed expectations.

The company appears to be winning competitively, particularly in optical networking where management cites being the 'number one winner' in a European market share disruption and displacement of the largest player in Europe. They report strong momentum, new Tier 1 customer wins in Europe, and 15 new optical customers added in the quarter, indicating share gains. While access and aggregation faces temporary headwinds from customer buying patterns, the underlying demand remains supported by fiber investments, and subscriber solutions show solid growth. The Mosaic One AI platform differentiation and early pilot results further suggest a competitive edge in intelligent network solutions.

  • Revenue: $279.4 million, up 23% year over year and 5% sequentially
  • Optical networking revenue: up 47% year over year and 15% sequentially
  • Access and aggregation revenue: up 12% year-over-year
  • Subscriber solutions revenue: up 12% year-over-year and 21% sequentially
  • Non-GAAP gross margin: 42.1%, up sequentially and year over year
  • Non-GAAP operating profit: $15.1 million or 5.4% of revenue
  • Operating cash flow: $12.2 million; year-to-date free cash flow: $38 million
  • Cash, cash equivalents, and restricted cash: $101.2 million at end of Q3 2025
  • Recovery in access and aggregation revenue from two large European customers in Q4 2025 or early 2026
  • Continued ramp of Tier 1 European optical carrier shipments
  • Expansion of Mosaic One AI platform beyond pilots to broader deployment
  • Completion of Huntsville campus sale providing additional liquidity
  • Operating margin expansion toward 43% non-GAAP gross margin and double-digit operating margin long-term
  • Benefits from scale efficiencies creating operating leverage as revenue grows
  • Dependence on two large European customers in access and aggregation whose buying patterns cause quarterly volatility
  • Uncertainty in timing and scale of rip-and-replace activities in Europe (e.g., Germany Huawei restrictions)
  • Ability to sustain gross margin in the 42% to 43% range long-term amid product mix and cost fluctuations
  • Execution risk in monetizing non-core assets (Huntsville campus) on desired terms and timing
  • Whether operating expense discipline can be maintained to drive operating margin expansion without increased R&D spend
  • Impact of currency volatility despite natural hedging framework

Management acknowledges that data center speeds and capacity are starting to affect the overall market but states this is 'not really in numbers today.' They position ADTRAN as uniquely situated at the intersection of structural shifts from core to edge computing and intelligent networks, with their portfolio (optical, access, aggregation, subscriber, Mosaic One) built to support the cascade of investment in AI and cloud computing through metro transport, access, aggregation, and subscriber edge. However, there is no direct evidence of current data center revenue exposure or specific data center-related orders in the transcript; the connection is framed as a forward-looking market trend rather than a present-day business driver.

  • What is the expected quarterly revenue run-rate recovery in access and aggregation from the two large European customers, and in which specific month does management anticipate their return to historical purchasing patterns?
  • Beyond pilot programs, what is the timeline and expected revenue contribution from broader deployment of Mosaic One AI platform, and what are the key customer adoption milestones for 2026?
  • What is the anticipated net proceeds range and expected closing timeline for the Huntsville campus sale, and how will those proceeds be allocated between debt reduction, share repurchases, and strategic investments?
  • What specific operating expense levers (beyond holding R&D flat) does management believe will drive operating margin expansion toward double digits, and at what revenue level does this become sustainable?
  • How does management quantify the near-term revenue opportunity from European rip-and-replace activities (e.g., Germany Huawei restrictions), and what is the expected conversion rate from current discussions to actual orders over the next 12–18 months?
  • Given that non-U.S. revenue was 57% of total in Q3, what is the breakdown of that non-U.S. revenue by region (e.g., Europe vs. other), and how is currency exposure managed in high-volatility markets outside the natural hedging framework?

Turning to the agenda, Tom Stanton, ADTRAN Holdings CEO and Chairman of the Board, will provide key highlights of the third quarter of 2025. Tim Santo, our Senior Vice President and CFO, will review the quarterly financial performance in detail and provide our fourth quarter 2025 outlook, and then we will take any questions you may have. I'd like to now turn the call over to Tom Stanton. Tom Stanton | CEO & Chairman of the Board: Thank you, Peter. Good morning, everyone. AdTrend delivered solid third quarter results with revenue near the upper end of our guidance and higher operating margins. All three business categories achieved double-digit year-over-year growth, reflecting disciplined execution, new customer wins, and healthy demand for fiber networking solutions. Operating profit exceeded the midpoint of our outlook, underscoring the solid execution and our focus on leveraging financial performance as a driver of longer-term value creation. The quarter was led by strong results in optical networking and subscriber solutions, while access and aggregation reflected anticipated buying patterns of two large European customers. we expect those customers to come back online either late in the fourth quarter or early next year. We remain confident on the overall market for the remainder of this year, however. During the quarter, we closed on a $201 million financing transaction that lowered our borrowing costs and increased financial flexibility, important steps that strengthen our capital structure and position us to execute confidently on longer-term strategic objectives. Turning to the quarter results, AdTrend reported $279.4 million, reflecting strong year-over-year growth across all three revenue categories. This marks the fifth consecutive quarter of sequential growth and fourth consecutive quarter of year-over-year improvement, proof points that our portfolio strategy and market positioning are driving sustainable momentum. This consistency underscores the health of our business, continued improvement in market conditions, and the progress we are making in strengthening our foundation for the longer-term growth. From our customers' perspective, engagement across our portfolio continues to strengthen as we broaden our technology reach. We're making it easier to choose AdTrans, not just because of what we build, but because of how seamlessly our solutions work together. Our integrated portfolio means fewer handoffs, faster time to value, and one accountable partner across optical access, subscriber, and software. Our technology is the enabler, but the outcome is what matters. Simpler operations, greater efficiency, and a trusted relationship that continues to open new opportunities for collaboration. Our optical networking solutions grew 47% year over year and 15% sequentially, driven by strong momentum in Europe, including deployments with a new large service provider. We added 15 new optical customers in the quarter, reflecting continued share gains and the expanding reach of our portfolio. Demand remains robust and geographically diverse, supporting a wide-range array of applications. These include national networks throughout Europe, secure connectivity for major enterprises, and government clients worldwide with high-capacity interconnects for large-scale content providers. Access and aggregation revenue grew 12% year-over-year, supported by ongoing fiber access investments among regional operators in the U.S. and Europe. While revenues from our small and medium-service providers in the U.S. were substantially up, This increase was offset by this seasonal buying pattern of two major European customers. We added 14 new customers for our fiber access and Ethernet aggregation platforms, demonstrating continued traction across both new and existing markets. In subscriber solutions, revenue grew 12% year-over-year and 21% sequentially, driven by demand for both residential and wholesale applications. We added 18 new customers during the quarter as service providers continued expanding fiber reach and upgrading Wi-Fi capabilities. This quarter, we introduced Mosaic One Clarity, a new application built on our carrier-grade agentic AI platform that enables predictive maintenance, guided issue resolution, and proactive network optimization. Early results from customer pilots are promising, demonstrating a reduction of up to 75% in network-related trouble tickets. This is a strong validation of our AI-driven approach to network intelligence and a clear example of how innovation within Mosaic One is helping operators improve performance and efficiency. Structural shifts across our industry from core to edge computing and the advent of intelligent networks are reshaping connectivity worldwide. AI isn't just transforming data centers, it's redefining the entire network. The rise of distributed computing and edge processing is driving new requirements for bandwidth, latency, and reliability. fueling demand for high-capacity optical solutions, next-generation access platforms, and intelligent software to automate operations. AdTrend is uniquely positioned at the intersection with our differentiated portfolio and our Mosaic One operating platform. As investment accelerates in AI and cloud computing, upgrades will follow across the network through metro transport, access, and aggregation, and ultimately, the subscriber edge. Our optical networking, access and aggregation, subscriber solutions, and Mosaic One software are built for that cascade, delivering higher throughput, lower latency, and smarter, more efficient operations at scale. In summary, Q3 was another quarter of solid execution and strategic progress, marking a clear step forward in both performance and positioning. We delivered top-line momentum and profitability improvements while enhancing our ability to invest and operate with greater financial flexibility, all of which reflects the disciplined way our teams are executing across the business. More importantly, we are setting the foundation for sustained value creation. The actions we've taken to enhance efficiency, strengthen our balance sheet, and sharpen our focus are enabling us to operate from a position of greater agility and confidence. As Tim will discuss in more detail during the financial review, our scale efficiencies are creating meaningful operating leverage across the business. With disciplined cost control and strengthened balance sheet, we see line of sight to continue margin expansion and earnings growth as we move through 2026, all while maintaining the same financial discipline that has guided our progress. With that, I will turn the call over to Tim to review the financial results in more detail. Tim? Tim Santo | Senior Vice President & CFO: Thank you, Tom, and thank you all for joining us this morning. We delivered solid results in the third quarter, reflecting strong discipline, consistent execution across the business. As Tom shared, we achieved broad-based revenue growth, higher margins, and improved operational efficiency as benefits from increased scale began to take hold. Demand was strong in optical networking and subscriber solutions supported by healthy customer activity and continued broadband investment globally. Over the past quarter, we've reinforced the operational fundamentals of the business and enhanced our financial controls and processes to support growth. These actions strengthen reliability and transparency of our published results and position us to deploy capital effectively, aligning operational execution with long-term value creation. As Tom shared, the third quarter also marked a significant step in strengthening our capital structure. The $201 million transaction that we completed has lowered borrowing costs, improved liquidity, and substantially reduced risk. also unlocked significant availability under our revolving credit facility, it does not change the strategic priorities we've outlined to monetize our non-core assets. As many of you know, we recently engaged new partners to represent the sale of our Huntsville campus. Together, we have relaunched a targeted marketing process and are actively speaking with interested parties. We will remain disciplined on terms and timing and will provide updates as appropriate. Simply put, we are moving forward the process with focus and intent. Maintaining a healthy balance sheet remains a top priority. We've made tangible progress this year and our balance sheet today is more resilient, flexible, and better aligned to support long-term growth. Turning to the financial results for the third quarter of 2025. Revenue was $279.4 million, up 23% year over year and 5% sequentially, finishing at the high end of our guidance. Growth was broad-based, led by optical networking, which increased 47% year over year. Geographically, non-U.S. revenue accounted for 57% of total revenue, while the U.S. represented 43%. One customer contributed more than 10% of total revenue during the third quarter. Non-GAAP gross margin improved to 42.1%, up both sequentially and year over year, driven by scale efficiencies, product mix, and component cost reductions. We remain focused on sustaining gross margin in the 42% to 43% range over the long term. Non-GAAP operating profit rose to $15.1 million or 5.4% of revenue exceeding the midpoint of our outlook. On a sequential basis, operating profit increased by $7.1 million or 89% compared to $14.6 million from approximately zero in the prior year. Operating income during this same period has increased to 5.4% in Q2 2025, Q3 2025, from 3% in Q2 2025 and 0.2% in Q3 2024. Currency had a minimal impact on our earnings this quarter. While volatility persists across both revenue and expenses, our natural hedging framework continues to mitigate risk. Building on the stronger forecasting, reporting, and treasury processes established this year, we are now expanding our FX strategies to further protect our balance sheet and working capital. Non-GAAP tax expense in Q3 2025 was $3.5 million or an effective rate of 38.3%. Non-GAAP EPS was 5 cents compared to break even in Q2 2025 and compared to a loss of 7 cents one year ago. We continue to strengthen our financial position with working capital improving by $13.2 million. Accounts receivable increased by $13.9 million, resulting from increased sales, with DSO remaining relatively flat at 59 days. Inventory declined by $16.3 million, sequentially reducing days inventory outstanding by 11 days to 124. Accounts payable totaled $188.9 million, with days payable outstanding remaining flat at 70 days. we remain focused on maintaining a healthy balance sheet with our objective of achieving a net positive cash position. Operating cash flow was $12.2 million and year to date we've generated $38 million in free cash flow. We ended Q3 2025 with $101.2 million in cash, cash equivalents, and restricted cash, and importantly, a stronger liquidity position. In summary, Q3 reflects disciplined execution, profitability improvement, and continued financial progress. We entered the fourth quarter with confidence despite typical seasonal factors, fewer shipping days, holiday-related customer acceptances, and budget timing. While those dynamics remain, we expect solid demand and our execution to offset the usual headwinds. We expect revenue between $275 and $285 million, and anticipate a non-GAAP operating margin of 3.5 to 7.5%. We expect OPEX to remain relatively flat compared to Q3. We look forward to a strong finish to the year and remain focused on driving sustainable growth and maximizing long-term stockholder value. I now turn the call back to Tom for some concluding remarks. Tom Stanton | CEO & Chairman of the Board: Thanks, Tim. I think we'll open up to some questions first. Carly, at this point, we've opened up the question queue for any questions people may have. Carly | Conference Operator: Thank you. We will now begin the Q&A session. At this time, if you would like to ask a question, please press star followed by the number one on your telephone keypad. We'll pause for just a moment to compile the Q&A roster. Your first question comes from Michael Genovese with Rosenblatt Securities. Michael Genovese | Analyst at Rosenblatt Securities: Uh, great. Thanks very much. Um, I guess my first question is looking at the access and aggregation and the comments on the European, um, customers there, as well as the information put out by, um, uh, you know, uh, AdTran networks in Europe, uh, talking about, I think a little bit of a timing change. So my question is, is there, was there like a, you know, a push out, um, of some things? I mean, I know, I know the, uh, First half of the year tends to be seasonally stronger than the second half in that access and aggregation European business. But versus prior expectations, was there some kind of push out in the timing of some of those shipments? Tom Stanton | CEO & Chairman of the Board: There has been. There's been, let's say, push out alludes to the fact that there may be some risk in that. I don't think there's any risk. But there has been some changing in some of the timing. We have two big customers. that tend to be front end loaded. In fact, they, you know, two of our biggest customers in the year. And then the, one of the customers has a calendar that is offset from, you know, typical, you know, their financial calendar is different. So that means budget cycles are different, but yeah, there's always some puts and takes. So the answer is yes. Michael Genovese | Analyst at Rosenblatt Securities: Okay. And, you know, I'm sorry, I just, In terms of what you said, I think you gave us an update on the real estate, but I was a little bit just couldn't follow exactly what you said about. So could you talk about that again? Tom Stanton | CEO & Chairman of the Board: Sure. Basically, what Tim mentioned was we have put both buildings back onto the market. We are actually receiving... We've got multiple offers coming in, right, Tim? Let me let you cover that. Tim Santo | Senior Vice President & CFO: Go ahead. We've, in this past quarter, you know, where we left off, we had, we were under an exclusivity agreement and we pulled the buildings down while we were working through that. As we disclosed last quarter, they're back on the market and very actively being marketed. You know, both the parts of the campus we have interest from multiple parties and are having regular conversations. Michael Genovese | Analyst at Rosenblatt Securities: Okay. And then finally, I'm just going to, you know, kind of a bigger picture question, you know, which is, you know, traditionally telecom has not been a, you know, a super fast growth market, right? It's like telecom in general is a single digit growth market. Um, so, you know, if, if, if, if AdTran is going to grow higher than that, uh, you know, on the top line and, and be more of like a high single or double digit growth company, is it because there's fundamental acceleration in what you're, in what you're doing in fiber and access or you're gaining share? Um, or is it, is there some repositioning to higher growth markets? Like, you know, more data center exposure. How do we think about 2026 and what the drivers of the business are from a high level? Tom Stanton | CEO & Chairman of the Board: I kind of agree with everything you're saying. You typically see the telecom market in the single digits, kind of mid to high single digits. It kind of varies year to year from there. Our premise has been there is that typical growth. We do believe markets in general are that the effectively that the focus right now on data center speeds and data center capacity is starting to affect the overall market, although I don't think that's really in numbers today. But the premise is there's a significant market share disruption that's happening in Europe right now, and we are the number one winner in that market share grab that's going on in Europe. I mean, the largest player in Europe is being displaced. Michael Genovese | Analyst at Rosenblatt Securities: Oh, you know, last follow-up on that. Is there anything incrementally in Germany happening where I believe that Germany had already decided to kind of cap Huawei, but I'm not sure if they ripped and replaced yet. Could that become something incremental, actual rip and replacing of Huawei? Tom Stanton | CEO & Chairman of the Board: Yes, it could. I think over time, rip and replace is going to have to happen everywhere just because you have to maintain the network and you can't be getting new drops of code all the time. There are As you know, there's been a lot of talk over the last few weeks about trying to accelerate that process in Germany. I don't think there's been any material rip and replace at this point in time. I think what they've been trying to do is effectively cap utilization on an ongoing basis. Tim Santo | Senior Vice President & CFO: Thanks. I appreciate it. Carly | Conference Operator: Okay. Your next question comes from Brian Coons with Needham and Company. Brian Coons | Analyst at Needham & Company: Great, thank you. When asked about optical, it looks like the best quarter you've had there in a couple of years. Tom, any color you can give us in terms of trends, in terms of product mix, geomix within the optical domain would be helpful because optical is obviously gaining a lot of momentum with regard to cloud and AI spent really starting to ramp up. Thank you. Tom Stanton | CEO & Chairman of the Board: Yeah, I would agree with you on what the outcome of the quarter was, and I will tell you that the momentum there is is strong. It's both in the U.S. and in Europe. The quarter was definitely helped, though, by us picking up a larger Tier 1 in Europe, and we started initial shipments into that carrier. But we've kind of seen a de-thaw kind of across the market, most notably in Europe, though. So we're expecting a good year next year as well. Brian Coons | Analyst at Needham & Company: Great. And, you know, as Mike mentioned about the while we displacement opportunities, I mean, how would you, how would you broadly characterize those today with regards to deals you've won as well as prospective deals you hope to like in the next 12 months relative to revenue opportunity? Tom Stanton | CEO & Chairman of the Board: Thank you. Yeah, so it is a, it has been a significant positive influence, even going through the downturn with what we've won. But if you look at the number of carriers, that have actually converted like, you know, there's some discussion here on Germany. They've been slow and that momentum continues to build quarter over quarter. It definitely is impacting our numbers now and that impact will grow over the next two to three years. So it's definitely a positive mover. You know, let me add a little because I think there are different dynamics in the access versus optical space. I think there's a good chance that optical will probably will see an increase in momentum earlier on in the optical space. Access has been a constant just move, but there's millions of customers that are involved versus and because of that widespread infrastructure versus kind of optical moves on a project by project basis. Brian Coons | Analyst at Needham & Company: Got it. Great. And maybe one on margins, if I can sneak it in, around, are you guys happy with where you're at here at 42 non-GAAP? And do you think this is where you got it pegged, or is there a further upside we can aim for? Tom Stanton | CEO & Chairman of the Board: No, our longer-term goal is 43, and I think we're within line of sight to that. I think we'll be bumping up against that next year. Brian Coons | Analyst at Needham & Company: Yeah. Great. Thank you very much. Okay. Carly | Conference Operator: Your next question comes from Christian Swap with Craig Hallam. Christian Swap | Analyst at Craig-Hallam & Co.: Great. Some other players in the space have started mentioning that they've got their first bead orders. Would you anticipate an improved bead spending environment possibly impact you in calendar 26? Tom Stanton | CEO & Chairman of the Board: Yes. Yeah, that's a yes. That's an easy bar, but yes. I mean, it's starting to You know, it's been dead now for a while, but it's definitely, you know, there's a whole lot more activity going on there. So the answer is yes. Christian Swap | Analyst at Craig-Hallam & Co.: Is that something that you guys would, you know, anticipate seeing orders in the first half of calendar 26 or is that yet to be determined? Tom Stanton | CEO & Chairman of the Board: I think we'll see orders in the first half of 26. Christian Swap | Analyst at Craig-Hallam & Co.: Great. And then you guys talked about operating margin expansion in 2026. I know you've outlined the goal of getting to double digits eventually. But what should we think about the potential for operating margin expansion in calendar 26? Tom Stanton | CEO & Chairman of the Board: We expect to have expansion in 26. I mean, I think the key to, so gross margins have been fairly consistent and have been, I would say, over time, upwardly moving. The whole key to us is the operating expense line. That, of course, is impacted by effects, but the operating expense line on a kind of constant currency basis, if you look at year over year, we're at high 90s, which equates to kind of where we are right now. So we've been holding it firm. I think the real question is, how long can you hold it firm? Our belief at this point in time is that we have enough R&D firepower and the right product set to not have to substantially increase the R&D spend. We will continue to, you know, we have sales expense that is variable depending on the revenue to some extent, but structurally-wise, we don't see big movements right now required to get us to that kind of 300-ish, north of 300 level, which kind of gets us to our targets. So I would expect expansion through next year. But, Tim, let me let you answer. Any comments on that? Tim Santo | Senior Vice President & CFO: I think as we continue the expansion, you'll see 300 in the second half of next year or early 2027. And I think on a constant currency basis, you get to the double digits once you get somewhere around 315 in revenue. Christian Swap | Analyst at Craig-Hallam & Co.: Great. No other questions. Thank you. Carly | Conference Operator: Your next question comes from George Nutter with Wolf Research. George Nutter | Analyst at Wolfe Research: Hey, thanks very much, guys. I guess I'm just curious about, you know, the minority interest in the business with the old adverse shareholders. Any new perspectives there? Did you redeem any shares in the quarter? Any new thoughts in terms of how you deal with that obligation going forward would be great. Thanks. Tom Stanton | CEO & Chairman of the Board: Well, we're happy if they redeem at this point. You know, so we would like to see some. I think there was one redemption in the quarter. Tim Santo | Senior Vice President & CFO: It's in the subsequent events that happened early, early this quarter. But yeah, we continue to see nominal activity and you know, expect there to be some level of run rate. Tom Stanton | CEO & Chairman of the Board: Yeah, but yeah, nothing earth shattering. And like I said, it's well, that's stock is trading up right now. If you take a look at over the last six months, but redemptions are a good thing at this point. George Nutter | Analyst at Wolfe Research: Got it. Would you look to do anything proactive? I mean, obviously, you did the financing this quarter. Would you look to get more proactive with those shareholders? Is that something that's in the cards at this point? Or does it hinge on, you know, selling the buildings in Huntsville? Like, how do you think about that? Tom Stanton | CEO & Chairman of the Board: Well, without a doubt, selling that building does give us, you know, substantially more headroom. My sense is we'd be getting more actively engaged on that base towards the tail end of next year, we're probably still a few quarters away from that. Having said that, redemptions are a good thing. Okay. Brian Coons | Analyst at Needham & Company: Thanks. Carly | Conference Operator: Okay. Your next question comes from Tim Savojo with Northland Capital Markets. Tim Savojo | Analyst at Northland Capital Markets: Hey. Pardon me. Good morning. A non-core asset question to start with, and that centers on the old ADBA kind of sync and timing business. I assume you capture that in optical, although I really don't know. That's one question. I wonder if you can give us a sense of the dynamics around the business, kind of overall ties, growth rate, profitability, anything you can share along those lines. I have a follow-up. Thanks. Tom Stanton | CEO & Chairman of the Board: Yeah, it is in the access and ag business. We really don't break that out separately, but, um, it's in the access and business access and ag business access and ag category. Um, it is, uh, growing, as you know, we're doing a kind of a relook at that business and segmenting that business to be able to, that is a different business. It is a different selling rhythm, different self type of, uh, I'll say people, but it's really different contexts within the different customer bases. So we're in the midst right now of, let's say, readjusting how that business operates. Tim Savojo | Analyst at Northland Capital Markets: Okay, thanks. And can you hear me? Tom Stanton | CEO & Chairman of the Board: Yeah, yeah, go ahead. Tim Savojo | Analyst at Northland Capital Markets: Okay, sorry. The second question was going to be on any impact from memory prices, especially on the subscriber side of the business and what you're seeing there. Tom Stanton | CEO & Chairman of the Board: There has there has been some that's been over some period of time, but nothing that's I would say the gross margin that business we've been able to keep. Let me think about that. Let me think about the proper answer. The gross margin of that business we've been able to keep at a fairly constant level over the last few quarters. And I think we'll be able to do that on a going forward basis. A lot of that is just churn on different, that business churns. We have new generations of subscriber product. We have more new generations of subscriber product than any other product in our portfolio. Tim Savojo | Analyst at Northland Capital Markets: Got it. Maybe one more for me. You mentioned starting to ramp with one of the tier one European winds, I guess, on the optical side. And I think that wind included access as well. So do you expect that to start ramping soon? And anything else to call out in terms of upcoming tier one ramps here in the next quarter or two? Tom Stanton | CEO & Chairman of the Board: Yeah, I think that one will... It will take longer. The optical thing was incredibly quick, and there was a lot of work that went in front of that in order to make that happen so quick. I think the access portion will take longer, but we'd expect to see movement of that next year. And in general, everything is moving forward, not at the pace that we would like, but everything in Europe is moving forward. We haven't lost any pieces. um the other ones that we've talked about in the past with very specific um there is some rip and replace going on in different parts of europe that is moving forward so um i think all of that would just be kind of a positive you know tailwind next year thanks okay there are no further questions at this time i'll now turn the call back over to tom stanton for closing remarks Okay, thanks very much for joining us on our conference call. And I really would like to extend my appreciation to our teams around the world. Thank you for everything that you do. I also want to thank our stockholders and our customers and partners for the confidence and the collaboration that you've shown us over the last year or so. Thanks very much, everybody. Carly | Conference Operator: Ladies and gentlemen, that concludes today's call. Thank you all for joining. You may now disconnect. jsPDF 3.0.3 D:20260608224822-00'00'

Research summary and source transcript

readyJun 10, 2026

ADTRAN delivered solid Q2 2025 results with revenue growth across all three segments, driven by strong demand in optical networking and fiber access, particularly from U.S. and European service providers. The company reported improved cash generation and balance sheet strength, with operating cash flow of $32.2 million and free cash flow of $18.3 million. While management expressed optimism about sustained growth and AI-related opportunities, no new guidance or material forward-looking disclosures were provided beyond the Q3 outlook.

The transcript does not contain evidence of material non-public information that management possesses today which the market will not learn for 6-24 months. All discussed trends—such as demand for fiber broadband, optical networking growth, AI-driven network operations, and service provider spending normalization—are framed as observable market developments. Management did not disclose proprietary customer contracts, unpublished product roadmaps, or internal forecasts beyond the stated Q3 2025 revenue and margin guidance. Any optimism about AI infrastructure or data center interconnect (DCI) opportunities is characterized as early-stage and speculative, with no quantifiable pipeline or customer commitments disclosed.

Revenue growth is driven by: (1) demand for advanced fiber and optical solutions from service providers upgrading infrastructure, (2) expansion of fiber access platforms (particularly SDX series) in Europe and mid-sized U.S. markets, and (3) growth in subscriber solutions fueled by residential broadband upgrades and multi-gigabit demand, supported by bundled offerings and new product launches like the SDG9000 series.

  • Revenue growth across all three segments (optical, access/aggregation, subscriber solutions)
  • Cash flow generation and balance sheet improvement (operating cash flow, free cash flow, liquidity)
  • Demand trends in fiber broadband, 5G densification, and AI-related network infrastructure
  • Customer expansion and cross-selling, including new optical and fiber access wins
  • Progress on non-core asset monetization (Huntsville campus, East Tower sale leaseback)
  • Foreign exchange impact and hedging strategy development
  • Detailed discussion of 50GPON commercial deployment in the U.K. using SDX6400 series as a sign of innovation leadership
  • Enthusiasm about AI applications in Mosaic Software Suite lowering network operating costs and improving subscriber experience
  • Emphasis on new customer wins in optical networking (18 new customers) and subscriber solutions (20 new service provider/government customers)
  • Optimism about sustaining growth in access and aggregation due to SDX platform momentum (10M+ homes passed)
  • Positive tone regarding U.S. service provider strength and tier-two/tier-three carrier expansion

Management exhibited a candid and measured tone, balancing optimism with realism. Executives avoided overpromising, frequently qualifying statements with phrases like 'it's still early,' 'I don't really have that number,' or 'we don't want to get too ahead.' They acknowledged challenges such as FX headwinds, customer concentration, and execution risks in asset sales. The tone was transparent about uncertainties (e.g., tariffs, guidance limitations under German disclosure rules) and grounded in observable trends rather than hype. This suggests credibility and a focus on disciplined communication, though it also limited the depth of forward-looking insight provided.

  • No clear dodged analyst question was detected by the local fallback; manual review should still check whether Q&A answers quantified conversion, margins, and guidance.
  • There may be a benchmark or metric-framing issue worth manual review, especially around adjusted metrics, timelines, or changed expectations.

The company appears to be gaining competitive momentum, particularly in optical networking and fiber access, supported by market share gains in tier-two and tier-three U.S. carriers, strong European service provider expansion, and new customer wins. Management highlighted cross-selling success and product-led differentiation (e.g., SDX platform, 50GPON) as evidence of strengthening position. However, the lack of disclosure on Tier 1 carrier progress or direct data center equipment competitiveness limits a full assessment. Overall, competitive positioning appears to be improving in core segments but remains unproven in high-growth, high-barrier areas like hyperscale data center infrastructure.

  • Q2 2025 revenue: $265.1 million, up 17% year-over-year and 7% sequentially
  • Operating cash flow: $32.2 million; free cash flow: $18.3 million
  • Cash and cash equivalents: $106.3 million at quarter end, up $5 million sequentially
  • Optical Networking Solutions revenue: $90.1 million (34% of total), up 22% year-over-year
  • Access and Aggregation revenue: $91.2 million (34% of total), up 30% year-over-year
  • Non-GAAP gross margin: 41.4%, with long-term target of 42%-43%
  • Non-GAAP operating profit: $8 million (3% of revenue), above midpoint of prior -4% outlook
  • Q3 2025 outlook: revenue between $270M and $280M; non-GAAP operating margin of 3%-7%
  • Continued rollout of AI-driven network operations tools within Mosaic One suite, with live customer trials underway
  • Expansion of 50GPON deployments in the U.K. and potential for similar high-speed fiber projects in other regions
  • Growth in wholesale service provider contracts to connect AI infrastructure, cited as a demand driver for optical networking
  • Progress toward closing non-core asset sales (Huntsville, East Tower) to strengthen balance sheet and enable capital return
  • Anticipated benefit from U.S. service provider upgrades related to EPS bankruptcy-related infrastructure spending
  • Expected sequential growth in subscriber solutions due to backlog and expanded product portfolio (SDG9000 series)
  • Revenue growth remains dependent on volatile service provider spending cycles and macroeconomic conditions
  • Foreign exchange fluctuations continue to impact operating expenses, despite natural hedging
  • Success of AI-driven network operations software is early-stage, with no disclosed revenue contribution or customer scale
  • Dependence on a single customer representing over 10% of Q2 revenue creates concentration risk
  • Uncertainty around timing and proceeds from non-core asset sales (Huntsville campus, East Tower)
  • Tariff exposure and global trade policy risks are excluded from guidance due to ongoing uncertainty

Management acknowledged emerging opportunities in data center interconnect (DCI) and MoFIN networks where cloud providers contract local service providers to build infrastructure, noting they have won some business in this area. However, they characterized the opportunity as 'still early' with 'a lot of activity' but no quantifiable pipeline, revenue contribution, or customer commitments disclosed. The discussion was framed as speculative and exploratory, with no evidence of material current or near-term data center-related revenue impact. Any AI/data center exposure remains indirect and nascent, tied to broader service provider infrastructure upgrades rather than direct data center equipment sales.

  • What is the expected timeline and revenue contribution from AI-driven network operations software within the Mosaic Suite?
  • Can management provide updated progress or timelines for the Huntsville campus and East Tower asset sales?
  • What is the current pipeline and win rate for data center interconnect (DCI) and MoFIN opportunities with cloud providers?
  • How is the company mitigating customer concentration risk, particularly regarding the single customer exceeding 10% of revenue?
  • What specific product or geographic factors are driving the 30% year-over-year growth in Access and Aggregation?
  • How sustainable is the current free cash flow generation rate, and what are the key levers for further improvement?
  • What assumptions underlie the Q3 2025 revenue and margin outlook, particularly regarding service provider spending durability?
  • How is the company thinking about capital allocation post-deleveraging—dividends, buybacks, or reinvestment?

NASDAQ:ADTN Q2 2025 Earnings Call Transcript Generated on 6/9/2026 Conference Call Operator: Mr. Peter Schulman, Vice President, Investor Relations, you may begin your conference call. Peter Schulman | Vice President, Investor Relations: Thank you, Kate. Welcome, and thank you for joining us today for ADTRAN holding second quarter 2025 financial results conference call, and welcome to all those joining by webcast. During the conference call, ADTRAN representatives will make forward-looking statements that reflect management's best judgment based on factors currently known. However, these statements involve risks and uncertainties, including those detailed in our earnings release, our annual report on Form 10-K as amended, and other filings with the SEC. These risks and uncertainties could cause actual results to differ materially from those in our forward-looking statements, which may be made during the call. We undertake no obligation to update any statements to reflect events that occur after this call. During today's call, we will refer to certain non-GAAP financial measures. Reconciliation of GAAP to non-GAAP measures and certain additional information are also included in our investor presentation and our earnings release. We have not provided reconciliations of our third quarter 2025 outlook with regard to non-GAAP operating margin because we cannot predict and quantify without unreasonable effort all the adjustments that may occur during the period. The Investor Relations presentation has been updated and is available for download on the ATRAN Investor Relations website. Turning to the agenda, Tom Stanton, ATRAN Holding CEO and Chairman of the Board, will provide the key investment highlights for the second quarter 2025. Tim Santo, our Senior Vice President and CFO, will review the quarterly financial performance in detail and provide our third quarter 2025 outlook, and then we will take any questions that you may have. I'd now like to turn the call over to Tom Stanton. Tom Stanton | CEO and Chairman of the Board: Thank you, Peter. Good morning, everyone. ATRAN delivered solid second quarter results marked by stronger revenue performance, healthy profitability, and continued balance sheet improvements. As previously disclosed in our pre-announcement, revenue exceeded our expectations with sequential and -over-year growth across all three of our revenue categories. This performance reflects strong execution and market share gains coupled with an improving industry backdrop driven by renewed infrastructure investment, the normalization of service provider spending, and growing demand for advanced fiber and optical solutions. Importantly, cash generation remained healthy with $32.2 million in cash from operations and $18.3 million in free cash flow. I'm encouraged by the improving demand environment across our key market segments. These demand trends not only supported our strong Q2 performance, but also increased our confidence in our outlook for continued growth over the coming quarters. Turning to the quarterly results, ATRAN's revenue of $265.1 million was above the high end of our previous guidance range. All three revenue categories delivered sequential growth, and for the second straight quarter, each revenue category generated -over-year gains. This broad-based momentum reinforces the strong competitive positioning of our optical transport, fiber access, and subscriber solutions portfolios. As expected, the highest sequential revenue growth in the quarter came from our optical networking solutions, which grew 22% -over-year and 15% sequentially. This growth was driven by demand in both the U.S. and -U.S. regions, with the most significant gains coming from our U.S. service provider customers. New customer acquisition also remained strong with 18 new optical customers added during the quarter, including several cross-selling wins, further validating the synergies with our optical transport and fiber access portfolios. There are multiple application demand drivers fueling the investment in optical networks. These include the build-out of private compute infrastructure, the expansion of wholesale service providers to connect AI infrastructure, ongoing 5G densification, and upgrading critical infrastructure. Combining these application demands with new customer wins and a return to more normalized service provider buying patterns gives us optimism for sustained growth in this category. In access and aggregation, we followed a very strong first quarter with additional growth in the second quarter, growing an impressive 30% -over-year for the quarter. This category was led by the strength of our large European service providers and -mid-size U.S. service providers, with many of these customers not only expanding their fiber footprint, but also expanding their share of business with us. New customer acquisition with our fiber access platforms also remained healthy. The ongoing success in our access and aggregation solutions is being driven by the technical leadership shown in our SDX portfolio and the corresponding Mosaic Cloud software. In the last two years, more than 10 million homes have been passed with fiber using the SDX6330 alone, highlighting the momentum of the flagship platform in our fiber access portfolio. Demonstrating our ongoing commitment to innovation, we recently connected the first commercial 50GPON customers in the U.K. using our new SDX6400 series. These product investments paired with our strong regional presence in the U.S. and Europe, new customer wins, and the continued demand for high-speed fiber-based broadband has us well positioned to sustain this success into the future. Our subscriber solutions category grew 4% sequentially after a strong first quarter. Within this category, residential solutions performed particularly well, increasing 18% sequentially and 25% -over-year. Importantly, new customer acquisitions remained strong, with 20 new service provider and government customers added for our subscriber solutions category during the quarter. Subscriber solutions revenue is growing due to expanded fiber connectivity, rising multi-gigabit demand, and service providers adopting bundled broadband solutions covering both access and in-home needs. Our broad subscriber solutions portfolio covers residential, enterprise, and wholesale fiber services and is being expanded to address the unique needs of SMB, MDU, and community Wi-Fi with the launch of our SDG9000 series of products. The expanded offering, along with continued demand for high-speed fiber services and large-scale deployments of our complementary fiber access platform, is expected to result in further growth in this segment during this quarter. Our Mosaic Software Suite integrates our comprehensive fiber networking portfolio, which covers everything from the optical core to the customer premise. Leveraging this extensive range of solutions and advanced software capabilities, we are well positioned to facilitate the industry's transition towards AI-driven network operations. Live customers are currently in progress, featuring our new suite of AI applications, including advanced generative and agentic AI tools. These complement and enhance our Mosaic One offering. Early results highlight the ability of these applications to transform how networks are operated by substantially lowering network operating costs while improving the subscriber experience. In summary, we are encouraged by the progress we made during the second quarter, both financially and strategically. We delivered growth across all major revenue categories and advanced our position in key technology domains. Our continued investments in next-generation optical, fiber access, and subscriber solutions are translating into new customer wins and deeper engagement with existing accounts. The ongoing expansion of AI infrastructure, especially as it moves closer to the network edge, plays directly to our strengths. Looking ahead, we remain confident in our outlook for the second half of the year. Strong customer demand and disciplined execution position as well to deliver continued improvement in profitability and cash generation, both of which are central to our long-term strategy. With a differentiated portfolio, expanding global presence, and increasing relevance in next-generation network architectures, we believe AdTran is exceptionally well positioned to for sustained success. With that, I'll turn the call over to Tim, our CFO, to walk you through our financial results for the second quarter. And then following Tim's remarks, we'll open the call up to any questions you may have. Tim? Tim Santo | Senior Vice President and CFO: Thank you, Tom, and thank you for joining us this morning. As I shared last quarter, my focus remains on three key priorities, strengthening our capital structure, enhancing the capabilities of the finance organization, and deepening our engagement with stakeholders. These are fundamental to delivering long-term, sustainable value for our stockholders. We are making solid progress across each of these areas. First, we are taking meaningful steps to improve our capital structure. We generated $32.2 million in operating cash and $18.3 million in free cash flow this quarter, with $106 million of cash available on our balance sheet. We are advancing efforts to raise capital through the sale of non-core assets, including our Huntsville campus, which I will speak further shortly. Meanwhile, availability on our revolving credit facility has more than doubled and will continue to expand as we grow non-GAAP EBIT and accelerate our free cash flow. Second, we've strengthened our financial organization through strategic additions to my senior leadership team. These hires improve our ability to manage the complexities of our current structure and support execution. We will continue investing in talent to ensure finance remains a strategic asset of our business. Finally, we've deepened our engagement with external stakeholders. We've expanded participation in investor and industry conferences and are pursuing broader research coverage. We remain committed to transparency, listening, and increased accessibility as we execute our strategy and will continue to expand over the coming quarters. With that, let's take a look at the financial results for the second quarter of 2025. ADTRAN's second quarter performance reflects an improving industry environment and our ability to deliver strong operating results. We are adding new customers and expanding our presence with existing ones, driving market share gains, and we are continuing to scale our business. ADTRAN delivered second quarter revenue of $265.1 million up 17% year over year and 7% sequentially, exceeding the high end of our original guidance range and reinforcing strong execution and momentum. Our Network Solutions segment contributed revenue of $219.5 million, accounting for approximately 83% of total revenue in Q2 compared to 79% in the prior year. Our Services and Support segment generated $45.6 million of revenue, representing 17% of revenue in Q2 2025, compared to 21% in Q2 2024, largely resulting from the significant growth and outperformance in Network Solutions. Moving on to product categories. Our Optical Networking Solutions revenue was $90.1 million, or 34% of total revenue. As predicted, Optical Networking Solutions revenue was higher, growing by 22% year over year. Access and Aggregation delivered revenue of $91.2 million, or approximately 34% of total revenue, and increased 30% year over year. Subscriber Solutions was $83.8 million, or 32% of total revenue, increasing 2% year over year. Geographically, non-US revenue accounted for 55% of the total, while US revenue comprised 45%. Additionally, one customer represented more than 10% of our Q2 revenue. This quarter's non-GAAP gross margin was 41.4%. While gross margin was in line with previous trends, the quarter over quarter decline was primarily driven by product and customer mix, higher transportation costs, as we strategically reposition products to mitigate tariff exposure. We maintain our longer-term target ratio of 42% to 43%. Non-GAAP operating expenses were $101.7 million, up from $95.5 million in Q1 and $93 million in Q2 last year, mainly due to currency fluctuations and higher sales commissions. Non-GAAP operating profit was $8 million, or 3% of revenue, above the midpoint of our -4% outlook. This compares to 9.8 million, or .9% of revenue in Q1 2025, and 1.4 million, or .6% of revenue one year ago. The -over-year operating margin and profitability improvement was primarily driven by higher revenue. Although we tightly manage our costs, OPEX increased due to fluctuations in European currencies and higher sales-related expenses. Currency fluctuations were a meaningful factor this quarter. While we are generally well positioned from a natural hedging standpoint on profitability, we believe that looking ahead currency will continue to play a role in our financial results. Since joining AdTran in March, I've prioritized strengthening FX management, taking early steps to build a more robust hedging strategy. These efforts support our broader goal of enhancing transparency and resilience in a more complex global environment. Non-GAAP tax expense in Q2 2025 was $628,000, reflecting higher taxable income in the U.S. We reported a non-GAAP net loss of $256,000, or 0 cents, on an earnings per share basis. This compares to non-GAAP net income of 3 cents per share in Q1 2025, and a net loss of 13 cents per share in Q2 2024. Turning to the balance sheet and cash flow statement, in the second quarter we continued to make meaningful progress in strengthening our financial position. Networking capital improved by $21.7 million sequentially, reaching $226.6 million, supported by a continued reduction in inventories and stronger collections. Trade accounts receivable were $164.8 million at quarter end, resulting in DSO of 57 days, and improvement from 60 days in the prior quarter. Inventory levels declined to $240.1 million at the end of the quarter, a decrease of $13.6 million sequentially. Correspondingly, days inventory outstanding significantly decreased by 17 days to 135 days in Q2 2025. Accounts payable were $178.3 million, with days payable outstanding of 70 days. Strengthening our balance sheet remains a key strategic priority. As mentioned before, operating cash flow was $32.2 million, and we had free cash flow of $18.3 million for Q2 2025. This is compared to $24.5 million in Q1 2025, and $3.9 million during Q2 2024. We ended Q2 with $106.3 million in cash and cash equivalents, a $5 million sequential increase, reflecting solid improvement in our liquidity. It is worth noting that this increase was achieved net of certain AdTrend Networks SE share repurchases under our DPLTA agreement, underscoring our disciplined cash management and strong operational execution. We remain focused on materially strengthening our financial position in 2025 with the ultimate goal of achieving a positive net cash position. As mentioned earlier, we continue to evaluate opportunities to monetize certain non-core assets, including some of our Huntsville properties. Although we were close to closing a deal this past quarter, that deal is not yet finalized, and we continue to work on finding additional purchases for this unique property. Further, with our improved credit positioning, we are evaluating a sale leaseback transaction on our East Tower. We are approaching these decisions thoughtfully and increasingly from a position of strength. We are pleased with our second quarter performance and encouraged by the signs of continued improvement across the industry. We are beginning to experience the benefits of scale and expect that momentum to build in the second half as revenue growth continues. Foreign exchange has generally had a positive impact on our business in Q2, although it contributed to slightly higher operating expenses, largely due to the weaker US dollar relative to the euro. On a constant currency basis, we expect OpFex to remain consistent with prior quarter levels. As I mentioned since joining in March, I prioritize building stronger FX management and reporting capabilities. Our capital allocation remains focused on deleveraging and continuing to evaluate opportunities to streamline the portfolio. Before turning to our outlook for the third quarter, I want to briefly address our approach to guidance. A few weeks ago, we issued a press release preannouncing that Q2 revenue would exceed our prior guidance range. While that intraday disclosure update may have seemed atypical, it was required under German disclosure rules we inherited through the ADVA merger. These regulations mandate rapid public disclosure of any material deviation, positive or negative, from previously issued guidance. As such, we provide quarterly guidance rather than annual guidance to remain compliant and avoid unnecessary disclosure burdens. Looking ahead to the third quarter of 2025, we expect revenue between $270 million and $280 million and anticipate a non-GAAP operating margin of 3 to 7%. This outlook excludes potential tariff impacts due to ongoing uncertainty surrounding global trade policy and broader macroeconomic conditions.

We will now begin the Q&A session. At this time, I would like to remind everyone, in order to ask a question, press star then the number 1 on your telephone keypad. Our first question comes from the line of Brian Koontz with Nidham & Company. Your line is open. Brian Koontz | Analyst, Needham & Company: Great, guys. Thanks for the question and nice results there. You know, you had some real strength in your large SPs. I assume that's coming from Europe. And Tom, can you kind of maybe lay out kind of the trends you're seeing there, either in some of your larger existing accounts or some of the new ones you're actively ramping in Europe? Tom Stanton | CEO and Chairman of the Board: Yeah, sure. First of all, you're right. There was a lot of strength in Europe. And yeah, I mean, the large accounts did well, but we also saw strength specifically in optical and the US large service providers as well. So that was kind of, that was good to see. In general, the strength there is just the momentum there is just continuing to grow. I mean, we really don't see any slowdown. We think that the German carriers are getting, our German customer is getting stronger and more able to deploy. What's going on in the UK, I think you're aware of is continuing to really kind of beat where we had hoped it to be. So it's just continuing to move upward. The market itself is continuing to move towards, let's say, more and more towards making sure that they have the right vendor base, right, and removing Eastern vendors. We announced a, when last quarter, and I think we called it a Southern European, it was in Italy, and we actually, that's been quick. So we've actually started shipping towards the tail end of that quarter, some optical gear to that customer as well. So yeah, I would say everything looked positive. Brian Koontz | Analyst, Needham & Company: That's great. And maybe another kind of business topic here around data centers, which you talked about in the prepared remarks. When we were at OFC, we heard a little bit about emerging DCI opportunities and this concept of Mofin networks where the big cloud providers are contracting local SPs to build. Can you update us on that? Are you seeing that as an important trend? Is it meaningful at this point? And how would you characterize that opportunity for you? Tom Stanton | CEO and Chairman of the Board: Yeah, there is a host of different RFPs out there right now with service providers who are, and some of these are actually customer driven, so some of these are. You may have a big ICP come in and saying that they want to go to cover this. Then there are others that are just kind of more opportunistic and trying to make sure that their network is ready. But there's a ton of activity. We have won some business there, but I would say it's still early. There's just a lot of activity right now. Brian Koontz | Analyst, Needham & Company: Got it. Great. And maybe just one last, if I could, on the balance sheet. There were some redemptions of adversaries. How should we be, how should investors think about that relative to your expectations? Tom Stanton | CEO and Chairman of the Board: Yeah, let me touch on that and see if there's anything else to add to it, Tim. About half of that was actually we disclosed last quarter and then half of that was this quarter disclosure. In that case, it was the same person. We have been in discussions with them for quarters and I would say it was very well managed. I think we were glad to be able to get those shares back at the price that we were able to get those shares back at. Anything else, Tim? Tim Santo | Senior Vice President and CFO: I'd just say that that was largely an orderly transaction. Again, we're in contact with these investors. And done in an orderly way, it reduces the shares outstanding, which long term is a very positive thing. Brian Koontz | Analyst, Needham & Company: That's great. Thanks for the questions and nice job in the quarter. Tom Stanton | CEO and Chairman of the Board: Thank you. Conference Call Operator: Your next question comes from the line of Michael Genoves with Rosinblatt Securities. Your line is open. Michael Genoves | Analyst, Rosenblatt Securities: Great. Thanks very much. Tom, you mentioned a couple of times in the script, you talked about market share gains. Could we just double click on that and get some more thoughts on what you're seeing there? Yes. Tom Stanton | CEO and Chairman of the Board: You know what's going on in Europe and I would say there's probably nothing big there that changed other than the Italian one that we brought on. We picked up market share in the, I'll call it the tier two space, but the kind of competitive carrier space here in the US as we won some additional optical business. I'm going to guess here about 50% of that new business was where we added a customer that was buying either optical or fiber access and then they joined on with buying the other piece that they were not buying. And that was really good to see because that was kind of the premise of the acquisition that we did three quarters ago or three years ago. Tier two, tier three we added somewhere around 10 or 11 carriers during the quarter just for fiber access alone. And I mentioned we added 20 customers on the subscriber space. The majority of those were carriers and then the next largest segment was in government municipalities. So, that space as you know continues to be very active. George Nutter | Analyst, Wolfe Research: Great. Michael Genoves | Analyst, Rosenblatt Securities: Thanks. George Nutter | Analyst, Wolfe Research: And Michael Genoves | Analyst, Rosenblatt Securities: then, you know, if I go back a couple quarters ago on your reporting, there was a big emphasis on operating leverage. And then last quarter, you know, we had the Forex pop up, but it sounds like you're hedging that again or hedging that out now. So, I guess my question is, you know, do you expect to start talking about operating leverage again as being a key part of the story? Because, you know, again, we have that thread and it kind of got lost and I've been waiting for it to come back. So any thoughts on that issue would be helpful. Thank you. Tim Santo | Senior Vice President and CFO: You know, I think I'll highlight just on the Forex side, you know, it was generally EPS neutral because we are largely naturally hedged. What I'm working on internally with our bank groups and with some of our advisors is a hedging strategy that keeps it that way. You know, the challenge is you do see some volatility in the individual line items. Again, back to, you know, FX is, I'm sorry, OPEX, if you back out, the impact of currency were largely flat. But at an EPS level, it was neutral, slightly positive for the company. So what we really want to do is hedge against any further changes in the US dollar, which is active strategy. You know, ideally what I have is a constant currency model, which, again, I've been here a quarter, so we're still working some things internally and building out some additional capabilities within my team. But with a constant currency reporting, there will be more transparency to the true impact of FX and the benefits of our hedging strategies. Tom Stanton | CEO and Chairman of the Board: And just on a percentage basis, right, we are starting to see that this quarter, you know, if you take a look at the midpoint of our guidance on our EBIT, you'll see that that's moving up from where we ended up and where we were guiding to last quarter. So I think we're right at that tipping point now to where you'll start seeing that leverage. FX or no FX, you'll see that leverage. So yeah, we don't want to get too ahead on what we're projecting because, you know, things happened. But I would say we're right at that point right now. Michael Genoves | Analyst, Rosenblatt Securities: Okay, that's good. That's great for me. I'll pass it on. Thanks again. Conference Call Operator: Your next question comes from the line of Christian Schwab with Craig Hallam Capital Group. Your line is open. Mr. Christian, your line is open. Christian Schwab | Analyst, Craig Hallam Capital Group: Sorry, I was on mute. Thank you for staying with me. Just a follow up on the currency question, you know, in the hedging, you know, you assume constant currency. Can you just tell us, you know, your assumption for the dollar to euro exchange rate for the quarter, which you're assuming it will be until all your hedge strategies are in place? Tim Santo | Senior Vice President and CFO: Well, again, on an EPS basis, we're largely naturally hedged. So I expect on an EPS basis us to remain relatively neutral. We are net positioning a strong improvement in the dollar, but no material movements in the next three months. Christian Schwab | Analyst, Craig Hallam Capital Group: Great. And then my second question is regarding the U.S. revenue strength. Are you guys benefiting this quarter and do you anticipate benefiting in the second half of the year due to the bankruptcy of EPS? Tom Stanton | CEO and Chairman of the Board: Yeah, we right off the bat started getting calls. We've started shipping to multiple customers now in the U.S., predominantly in the U.S. I think we have some international business as well, but that's affected. That'll be a positive movement for us, both on the OLT side, on the infrastructure side, as well as on the subscriber side. It already has been. It's already started impacting us. Christian Schwab | Analyst, Craig Hallam Capital Group: Could you quantify that opportunity over, you know, multiple quarters to come or the positive impact that you received this quarter? Tom Stanton | CEO and Chairman of the Board: I don't really have that number. That's getting pretty granular. I would say across the business, it's probably in the 10-ish million, but, you know, that's when it is all rolling. Some of these things are still competitive. They're going out to RFP. Some of them, we have interoperable products, so we're an easy plug-in. So, where people were really in a bind, they kind of called us. But, yeah, I would say it's probably material, but it's not overly so. Christian Schwab | Analyst, Craig Hallam Capital Group: All right, great. No other questions. Thank you. Okay. Conference Call Operator: Your next question comes from the line of George Nutter with Wolfe Research. Your line is open. George Nutter | Analyst, Wolfe Research: Hi, thanks a lot, guys. Tim, I think you mentioned your efforts on the sale of the North Star Tower. It sounds like from your comments that that's, you know, you've had a particular buyer kind of walk away from the process. Is that correct? And what do you think the outlook is for getting a transaction done there? Thanks. Tom Stanton | CEO and Chairman of the Board: Yeah, let me start with the first piece, and then I'll turn back over to Tim. We didn't have a buyer walk away. We had a buyer that has been slow to close. So, they are still actively trying to get their side of the deal done. But based off of the timing differential, you know, we're now looking at offering it to other people. And before that, for a period of time, we were not. We had taken it off and we're trying to close the deal. That's still an active negotiation, but we are now looking at other offers as well. Tim, anything you want to add to that? I'd Tim Santo | Senior Vice President and CFO: just say we're, exactly, you know, we are under an exclusivity period. We have an inked deal, but, you know, there's contingencies that have kept us from moving that forward and those remain in place. We're tired, as you are, with some of these things moving. So, it's unique property. It's a tough property, but it's a gorgeous property. So, you know, we're not willing to give the property away for an amount that's at a fire sale. And we're also very selfishly aware of who's going to be our neighbor. So, we're working with some new parties to help us remarket the facility in parallel. And also, I mentioned, you know, re-exploring with our renewed strength and capital position a sale leaseback transaction on the East Tower. George Nutter | Analyst, Wolfe Research: Thank spk00: you. Conference Call Operator: Your next question comes from the line of Tim Savages for Northland Capital Markets. Your line is open. Tim Savages | Analyst, Northland Capital Markets: Hey, good morning. And congrats on the outlook in particular and some of that operating leverage that you're starting to show. And along those lines, I think you mentioned an expectation for subscriber solutions to grow in Q3, but I'd be looking for any other color from a segment or geographic perspective about where you expect that sequential growth to come from. I can follow up from that. Tom Stanton | CEO and Chairman of the Board: Yeah, so, yeah, we explicitly, you're right, I explicitly did point out subscriber solutions and that's just backlogging that area continues to grow. So, we kind of have more visibility as to what we expect there. Optical probably have a very strong core as well, that business and that backlog continues to grow and access continues. Backlog is probably not as big because we do have lumpy order patterning, but yeah, it's positive. I mean, the business itself is definitely trending positive. I don't, our visibility, as you know, is usually strongest in the next quarter and then it gets a little weaker and a little weaker. All of the signs that we have right now are looking upward. So, yeah, and I would say across all the product segments. Probably the strongest single area right now is optical because they have the most ground to make up. They had the inventory depletion cure itself the latest. At this point in time, I would say it's cured and we're just seeing strong activity there. Did that answer your question, hopefully? Tim Savages | Analyst, Northland Capital Markets: Sure did and leads very well into the next one, which is, you know, Tom, you've mentioned, or maybe both you guys have mentioned continued momentum in the second half in terms of revenues and cash flow. I mean, should we take that as implying an expectation for continued sequential growth into Q4? You know, you do at times have some seasonal headwinds there, or I know it's early, but I want to see if I'm interpreting that positive correctly. Tom Stanton | CEO and Chairman of the Board: Yeah, I'm going to, we don't give, as you know, guidance past the quarter, but I would say the momentum is strong enough to where I would not be surprised if we were to overcome any seasonal patterns at this point. Tim Savages | Analyst, Northland Capital Markets: Great. And maybe last one for me. You did see a good amount of sequential growth in the U.S. this quarter and I've talked about that to some degree, but should we, I guess, to what extent should we associate that with inventory, you know, burning off versus maybe some of the new wins you announced last quarter with the tier twos in the U.S. or what makes the factors, would you say, was driving that U.S. growth in particular? Tom Stanton | CEO and Chairman of the Board: I think you literally hit the mix. I think we did win some tier threes as well, but they tend to be smaller buyers, so you have to really have a big mass, and I would say we don't have a big mass yet. Tier twos can move the needle. They have started buying our optical products as well. So it was tier twos and the tier ones here in the U.S. are probably what drove the most. Enterprise also did good, but those two drove the most. I'm trying to think of the numbers. Those two definitely had the biggest impact. Tim Savages | Analyst, Northland Capital Markets: Okay, thanks very much. Conference Call Operator: Your next question comes from the line of Bill DeZell and with Titan and Capitals. Your line is open. Bill DeZell | Analyst, Titan Capital Group: Thank you. Relative to the strength that you were talking about, really around the globe, are you able to either rank or kind of highlight what's the true driver between the expanding bandwidth, the AI, the data centers, vendor replacement? There are all these factors that I think you've highlighted are favorable contributors, but are there one or two that are truly the meaningful drivers? Tom Stanton | CEO and Chairman of the Board: I would say the biggest driver right now is upgrade of the network, at least for us, right, is upgrade of the network for residential broadband. That's driving the biggest piece of our kind of revenue growth over the last few quarters. The next biggest driver, it gets optical returning to normality would definitely be the next one, and I would tell you, like I said, we're expecting a strong second half there. That normality, it's not just normality, it's new application wins. I mentioned we won some in Europe. We won some additional projects in Europe that include 5G densification, for instance, which is kind of nice to see. Then we're seeing some of the work, and have won some business around kind of getting just general bandwidth upgrades, and some of that is AI driven. It's kind of hard. Optical is multiple different things affecting optical. If you would just let me say fiber to the pram plus optical, that would be the right answer, because the fiber to the pram is also affecting our subscriber business, of course. Bill DeZell | Analyst, Titan Capital Group: That's helpful. Thank you, Tom. Then in the U.S., do you see any opportunity to crack into any of the Tier 1s that you are not currently a meaningful player with? Tom Stanton | CEO and Chairman of the Board: We sell to the other, well, let me define Tier 1 for you, if you don't mind. Tier 1 carrier customers, TOCO customers, we sell to them, but I don't see any real big change in trajectory in the near term there. For MSO customers, I think there's a difference. I think that we have products well positioned, and the larger MSOs here, and we could see some movement there. Does that answer your question? Bill DeZell | Analyst, Titan Capital Group: Yes, but it certainly does lead to another to expand on that last comment about winning additional, sounds like large MSO business. Tom Stanton | CEO and Chairman of the Board: Right. We're working at it. We have some approvals that we've gotten, and I think we're well positioned. Until I see that big PO coming in, I'm not going to really cut it, but we're approved and ready to go. Bill DeZell | Analyst, Titan Capital Group: Great. Congratulations on a really nice quarter. Tom Stanton | CEO and Chairman of the Board: All right. Thank you very much. I think with that, we are out of questions for today. So, I appreciate everybody joining us on the call today, and we look forward to talking to you next quarter. Thank you, everyone. Ladies and Conference Call Operator: gentlemen, that concludes today's call. Thank you for your participation. You may now log off. jsPDF 3.0.3 D:20260609232312-00'00'
