Speaker #3: Thank you, operator. Good morning, everyone. Although we are disappointed with the reported results of this past quarter, we believe they were driven by a specific set of factors.

Tom Stanton: Thank you, operator. Good morning, everyone. Although we are disappointed with the reported results of this past quarter, we believe they were driven by a specific set of factors. As we communicated in our preliminary results press release, a project delay from a single customer, combined with unfavorable impacts from product and customer mix, caused our results to fall short of our guidance. Despite these factors, demand across our end markets remains healthy. Our strategic priorities remain on track, and our customer base continues to diversify. We believe those underlying fundamentals position us well as we look ahead into 2027. As we shared in our pre-announcement, one of our customers adjusted the timing of a project which affected our results for the quarter. This customer remains committed to its deployment objectives, and we view this as a timing adjustment rather than a change in demand.

Speaker #3: As we communicated in our preliminary results press release, the project delay from a single customer combined with unfavorable impacts from product and customer mix caused our results to fall short of our guidance.

Speaker #3: Despite these factors, demand across our markets are end markets remains healthy. Our strategic priorities remain on track, and our customer base continues to diversify.

Speaker #3: We believe those underlying fundamentals position us well as we look ahead into 2027. As we shared in our pre-announcement, one of our customers adjusted the timing of a project, which affected our results for the quarter.

Speaker #3: This customer remains committed to its deployment objectives and we view this as a timing adjustment rather than a change in demand. Overall customer demand remains strong during the quarter, but a challenging supply environment limited our ability to fulfill that demand, constraining shipments and resulting in an unfavorable mix.

Tom Stanton: Overall customer demand remained strong during the quarter, a challenging supply environment limited our ability to fulfill that demand, constraining shipments and resulting in an unfavorable mix. To be clear, absent these incremental supply constraints, we would have met our original revenue guidance. Against this backdrop, ADTRAN delivered Q2 revenue of $281.1 million, consistent with our preliminary results, and non-GAAP operating margin of approximately 3.8%, also in line with our pre-announcement. While these results reflected the items I just discussed, several indicators of our strategic progress continued to strengthen during the quarter. Our optical business continued to serve as a key growth engine, and our growth was broad-based across service provider, enterprise, government, and cloud customers, and reflects continued demand for higher capacity optical infrastructure, AI-driven networking expansion, and secure connectivity. We are also generating tangible benefits from our diversification strategy.

Speaker #3: To be clear, absent these incremental supply constraints, we would have met our original revenue guidance. Against this backdrop, ADTRAN delivered second quarter revenue of $281.1 million consistent with our preliminary results, and non-GAAP operating margin of approximately $3.8%.

Speaker #3: Also in line with our pre-announcement, while these results reflected the items I just discussed, several indicators of our strategic progress continued to strengthen during the quarter.

Speaker #3: Our optical business continued to serve as a key growth engine and our growth was broad-based across service provider enterprise, government, and cloud customers, and reflects continued demand for higher capacity optical infrastructure.

Speaker #3: AI-driven networking expansion, and security-connect secure connectivity. We are also generating tangible benefits from our diversification strategy. Revenue from enterprise, government, and cloud customers grew a strong $47% year over year, and 19% sequentially, accounting for 25% of total company revenue in the quarter.

Tom Stanton: Revenue from enterprise, government, and cloud customers grew a strong 47% year-over-year and 19% sequentially, accounting for 25% of total company revenue in the quarter. Within this customer segment, revenue from hyperscalers increased 97% year-over-year, underscoring the strength of our diversification strategy. This momentum is being driven primarily by our data center interconnect business. In parallel, we continue to expand engagements with hyperscalers and large-scale content providers for our upcoming MicroMux Quattro and the LiteWave800 pluggable optics solutions. The results highlight our growing participation in attractive end markets beyond our traditional service provider base, and reflect the opportunities created by continued investment in cloud and AI infrastructure. As we broaden our customer adoption and expand our solutions footprint, we believe we are well positioned to benefit from these longer-term growth trends. Secure connectivity is another area where we continue to drive increasing customer demand.

Speaker #3: Within this customer segment, revenue from hyperscalers increased 97% year over year, underscoring the strength of our diversification strategy. This momentum is being driven primarily by our data center interconnect business, in parallel we continue to expand engagement with hyperscalers and large-scale content providers for our upcoming microquartile and the light wave 800 pluggable optics solutions.

Speaker #3: The results highlight our growing participation in the attractive end markets beyond our traditional service provider base and reflect the opportunities created by continued investment in cloud and AI infrastructure.

Speaker #3: As we broaden our customer adoption and expand our solutions footprint, we believe we are well positioned to benefit from these longer-term growth trends. Secure connectivity is another area where we continue to drive increasing customer demand.

Speaker #3: Our recently announced collaboration with EU Networks highlights growing demand for quantum-safe networking solutions and validates the strength of our multi-layer encryption portfolio and integrated cryptographic management capabilities, as service providers and enterprises place greater urgency on addressing quantum-secure vulnerabilities.

Tom Stanton: Our recently announced collaboration with euNetworks highlights growing demand for quantum-safe networking solutions and validates the strength of our multilayer encryption portfolio and integrated cryptographic management capabilities as service providers and enterprises place greater urgency on addressing quantum-secure vulnerabilities. Within our service provider segment, we continue to unlock opportunities driven by vendor replacement programs, network modernization initiatives, broadband expansion efforts, and increasing security requirements. These trends are driving investment across transport and access networks and position us to benefit from large-scale broadband initiatives such as BEAD in the US, Project Gigabit in the UK, Germany's Gigabit Strategy 2030, and Italia 1 Giga, alongside growing demand streaming from European network security and trusted vendor initiatives, including the proposed EU Cybersecurity Act 2 or CSA 2. Now, some specifics of our product categories. Optical Networking Solutions revenue was $109.7 million, up 22% year over year and 13% sequentially.

Speaker #3: Within our service provider segment, we continue to unlock opportunities driven by vendor replacement programs, network modernization initiatives, broadband expansion efforts, and increasing security requirements.

Speaker #3: These trends are driving investment across transport and access networks and position us to benefit from large-scale broadband initiatives such as Bead in the US, Project Gigabit in the UK, Germany's Gigabit Strategy 2030, and Italia's One Giga, alongside growing demand streaming from European network security and trusted vendor initiatives, including the proposed EU cybersecurity act 2 or CSA 2.

Speaker #3: Now, some specifics of our product categories. Optical networking revenue was $109.7 million, up 22% year-over-year and 13% sequentially. Access and aggregation solutions revenue was $86.9 million and was directly impacted by the customer timing dynamics I discussed earlier.

Tom Stanton: Access & Aggregation Solutions revenue was $86.9 million and was directly impacted by the customer timing dynamics I discussed earlier. Subscriber Solutions revenue was $84.5 million, reflecting normal variability following a very strong Q1. Subsequent to quarter end, we strengthened our financial foundation through the completion of a senior secured credit facility. This refinancing lowers borrowing costs and extends maturities, providing additional financial flexibility as we execute our long-term strategy. In summary, the underlying drivers of our business remain intact, and demand for our products is strong. Although the company's gross margin performance has continued to improve over the last three years, including being able to overcome the product and freight cost increases we have experienced over the last few quarters, Q2 results reflected a tightening of supply, which resulted in unfavorable product mix as our ability to ship higher margin products was impacted, and ultimately lowered gross margins.

Speaker #3: And ultimately lowered gross margins. As the supply chain outlook remains uncertain, we continue to advance actions that will strengthen our margins and better align our performance with our long-term operating objectives of 42 to 43% gross margin.

Tom Stanton: As the supply chain outlook remains uncertain, we continue to advance actions that will strengthen our margins and better align our performance with our long-term operating objectives of 42% to 43% gross margin. Amidst the current supply environment, we are maintaining strong OpEx control and remain committed to our 10% non-GAAP operating margin target. We continue to gain momentum in Optical Networking Solutions, further diversifying our customer base and see a clear path forward towards improving profitability. We remain confident in our strategy and our ability to create long-term shareholder value. With that, I'll turn the call over to Tim to review our financial results in greater detail and follow up with questions. Tim?

Speaker #3: Amidst the current supply environment, we are maintaining strong operating expense control and remain committed to our 10% non-GAAP operating margin target. We continue to gain momentum in optical networking, further diversifying our customer base, and see a clear path forward towards improving profitability.

Speaker #3: We remain confident in our strategy and our ability to create long-term shareholder value. With that, I'll turn the call over to Tim to review our financial results in greater detail and follow up with questions.

Speaker #3: Tim?

Speaker #2: Thank you, Tom. And thank you all for joining us today. Revenue for the quarter was $281.1 million. Representing growth of 6.1% compared to the second quarter of 2025.

Tim Santo: Thank you, Tom, and thank you all for joining us today. Revenue for the quarter was $281.1 million, representing growth of 6.1% compared to the Q2 2025. Geographically, US revenue was $134.4 million, representing approximately 48% of total revenue, up 12% year over year. Non-US revenue was $146.7 million, representing approximately 52% of total revenue, and up 1% year over year. By product category, Optical Networking Solutions revenue was $109.7 million or 39% of total revenue, increasing 22% year over year and 13% sequentially. Access & Aggregation Solutions revenue was $86.9 million or approximately 31% of total revenue. While down 5% year over year and 4% sequentially, US access and aggregation revenues were up a healthy 13% year over year, partially offsetting the non-US customer order timing described earlier.

Speaker #2: Geographically, U.S. revenue was $134.4 million, representing approximately 48% of total revenue, up 12% year-over-year. Non-U.S. revenue was $146.7 million, representing approximately 52% of total revenue and up 1% year-over-year.

Speaker #2: Subscriber solutions revenue was $84.5 million or 30% of total revenue up 1% year over year and down 14% sequentially following a strong first quarter.

Tim Santo: Subscriber Solutions revenue was $84.5 million, or 30% of total revenue, up 1% year-over-year and down 14% sequentially following a strong Q1. Turning to margins. Non-GAAP gross margin was 40.7% compared to 41.4% in Q2 2025 and 43% in Q1 2026. Gross margin reflected the factors Tom discussed earlier, primarily the combination of product mix, customer mix, and higher product costs. Non-GAAP operating expenses were $103.9 million compared to $103.3 million in Q1 2026 and $101.7 million in Q2 2025. As we continue to actively manage operating expenses related cost against inflationary pressures. Non-GAAP operating income was $10.6 million, resulting in non-GAAP operating margin of 3.8%, compared to $8 million and 3% on a year-over-year basis, however, down from $19.9 million and 6.9% on a sequential basis.

Speaker #2: Turning to margins, non-GAAP gross margin was 40.7% compared to 41.4% in the second quarter of 2025 and 43% in the first quarter of 2026.

Speaker #2: Gross margin reflected the factors Tom discussed earlier, primarily the combination of product mix, customer mix, and higher product costs. Non-GAAP operating expenses were $103.9 million, compared to $103.3 million in the first quarter of 2026 and $101.7 million in the second quarter of 2025.

Speaker #2: And as we continue to actively manage operating expenses, related cost against inflationary pressures. Non-GAAP operating income was 10.6 million resulting in non-GAAP operating margin of 3.8% compared to 8 million and 3% on a year-over-year basis; however, down from 19.9 million and 6.9% on a sequential basis.

Speaker #2: Non-GAAP tax expense during the quarter was 2.6 million reflecting an effective non-GAAP tax rate of 33.7%. Non-GAAP net income attributable to ADTRAN Holdings was 3.4 million or 4 cents per diluted share compared to break-even results in the second quarter of 2025 and 11 million and 14 cents in the prior quarter.

Tim Santo: Non-GAAP tax expense during the quarter was $2.6 million, reflecting an effective non-GAAP tax rate of 33.7%. Non-GAAP net income attributable to ADTRAN Holdings was $3.4 million, or $0.04 per diluted share, compared to breakeven results in Q2 2025 and $11 million and $0.14 in the prior quarter. Turning now to the balance sheet and cash flow. We continued to make progress improving our working capital metrics during the quarter with $245.2 million of net working capital at quarter end. Inventory was $208.8 million, with days inventory outstanding of 107 days, down 3 days sequentially. Trade accounts receivable were $205.8 million with DSO of 67 days, down 1 day sequentially. Accounts payable were $169.3 million, with DPO of 65 days, also down 1 day sequentially. These improvements contributed to operating cash flow of $25.9 million during the quarter and free cash flow of $8.7 million.

Speaker #2: Turning now to the balance sheet and cash flow, we continued to make progress improving our working capital metrics during the quarter, with $245.2 million of net working capital at quarter-end.

Speaker #2: Inventory was $208.8 million with days inventory outstanding of $107 days down 3 days sequentially. Trade accounts receivable were $205.8 million with DSO of $67 days down 1 day sequentially.

Speaker #2: Accounts payable were $169.3 million, with DPO of 65 days, also down 1 day sequentially. These improvements contributed to operating cash flow of $25.9 million during the quarter and free cash flow of $8.7 million.

Speaker #2: We ended the quarter with $79.2 million of cash and cash equivalents net repurchases of ADTRAN Networks SE shares and dividend payments made during the quarter of $22.6 million.

Tim Santo: We ended the quarter with $79.2 million of cash and cash equivalents, net repurchases of ADTRAN Networks SE shares and dividend payments made during the quarter of $22.6 million. This compared to $88.3 million at 31 March 2026. Also of note, we recently completed the refinancing of our credit facility led by JPMorgan. This new facility replaces our prior credit agreement while maintaining total revolver capacity, reducing borrower costs by 200 basis points, and extending our maturity to 2031. Turning our outlook to Q3. We expect revenue to be between $275 million and $295 million, and non-GAAP operating margin to be between 1.5% and 5.5%. Our outlook reflects the current expectations regarding customer deployment timing, supported by continued strength in the Optical Networking Solutions business, healthy demand across cloud, enterprise, and government markets. This concludes our prepared remarks.

Speaker #2: This compared to 88.3 million at March 31st, 2026. Also of note, we recently completed the refinancing of our credit facility led by JPMorgan. This new facility replaces our prior credit agreement while maintaining total revolver capacity reducing borrower costs by 200 basis points and extending our maturity to 2031.

Speaker #2: Turning our outlook to the third quarter, we expect revenue to be between $275 million and $295 million, and non-GAAP operating margin to be between 1.5% and 5.5%.

Speaker #2: Our outlook reflects the current expectations regarding customer deployment timing supported by continued strength in the optical networking solutions business, healthy demand across cloud, enterprise, and government markets.

Speaker #2: This concludes our prepared remarks. However, before turning the call back to Tom, I'd like to note that we will be participating in the Rosenblatt Virtual Technology Summit on August 17th and the B.

Tim Santo: However, before turning the call back to Tom, I'd like to note that we will be participating in the Rosenblatt Technology Summit on 17 August and the B. Riley TMT Conference in New York on 10 September. We hope to see many of you there, and with that, I'll turn the call back to Tom.

Speaker #2: Reilly TMT Conference in New York on September 10th. We hope to see many of you there, and with that, I'll turn the call back to Tom.

Speaker #1: Thanks very much, Tim.

Tom Stanton: Thanks very much, Tim. Okay. At this point, we are ready to open up for any questions people may have.

Speaker #2: Okay. At this point, we're ready to open up for any questions people may have.

Operator: We will now begin the question and answer session. If you would like to ask a question at this time, just press star followed by the number one on your telephone keypad. If you would like to withdraw your question, press star one again. We will pause for a moment to compile a Q&A roster. Our first question comes from the line of Irvin Liu with Evercore ISI. Irvin, please go ahead.

Speaker #3: We will now begin the question and answer session. If you would like to ask a question at this time, just press star followed by the number one on your telephone keypad.

Speaker #3: And if you would like to withdraw your question, press star one again. We will pause for a moment to compile the Q&A roster. And our first question comes from the line of Ervin Liu with Evercore ISI.

Speaker #3: Ervin, please go ahead.

Speaker #1: Hi. Thank you for the question. Tom, can you help us understand the nature of the project delay at the single large customer? Is this more of a financial or strategic decision on their end, and what gives you assurance that this is demand deferred and not demand destroyed?

Irvin Liu: Hi. Thank you for the question. Tom, can you help us understand the nature of the project delay at the single large customer? Is this more of a financial or strategic decision on their end? What gives you assurance that this is demand deferred and not demand destroyed?

Speaker #4: Well, the biggest assurance that we have, and of course we do talk to them on a very, very regular basis, but the biggest assurance that we have is they've come out and recommitted to their plan.

Tom Stanton: Well, the biggest assurance that we have, of course, we do talk to them on a very regular basis. The biggest assurance that we have is they have come out and recommitted to their plan. Including the timing of their plan, it is a very visible, very easy to check on number. Those plans have not changed. I think really what may be a high-level way to look at it is they have multiple plans now in flight. Some of them include the normal footprint expansion that we have been involved in for a few years now. Some of it has to do with Huawei replacement or vendor replacement, which is kicking off. Some of it has to do with upgrades and speed, then some of it has to do with expanding that footprint expansion to even a greater extent than they had initially planned.

Speaker #4: So including the timing of their plan, and it's a very visible very easy to check on number. So and those plans haven't changed. So I think really what maybe a highway a high-level way to look at it is they have multiple plans now in flight.

Speaker #4: Some of them include the normal footprint expansion that we've that we have been involved in for a few years now. Some of it has to do with wide wave replacement or vendor replacement, which is kicking off.

Speaker #4: Some of it has to do with upgrades and speed and then some of it has to do with expanding that footprint expansion to even a greater extent than they had initially planned.

Speaker #4: All of those are in flight, but what we're seeing right now is kind of a repositioning of priorities within those different buckets and you know we may see one of the other ones kick in.

Tom Stanton: All of those are in flight, but what we're seeing right now is kind of a repositioning of priorities within those different buckets. We may see one of the other ones kick in. We expect to see one of the other ones kick in sooner than originally planned. This is all just kind of getting all the plans in place before they move forward, and they have enough inventory to continue to deploy at their committed rate as they kind of reposition these plans. Did that answer the question?

Speaker #4: We expect to see one of the other ones kick in sooner than originally planned. And this is all just kind of getting all the plans in place before they move forward.

Speaker #4: And they have enough inventory to continue to deploy at their committed rate as they kind of reposition these plans. Does that. That's another question.

Irvin Liu: Got it.

Tom Stanton: Did that make sense? I know it's a long, drawn-out answer, but

Speaker #4: Does that make sense? I know it's a long drawn-out answer, but.

Speaker #1: That did, Tom. Thank you. And then for my follow-up, I guess it's good to see your commitment to your 10% operating margin target and you're currently at low to mid single digits due to product mix headwinds in addition to component and freight cost headwinds.

Irvin Liu: That did, Tom. Thank you. For my follow-up, I guess it's good to see your commitment to your 10% operating margin target, and you're currently at low to mid-single digits due to product mix headwinds in addition to component and freight cost headwinds. Can you discuss any sort of margin mitigation strategies you might have, and walk us through the path from low to mid-single-digit operating margins currently to perhaps low double-digit margins longer term?

Speaker #1: But can you discuss you know any sort of margin mitigation strategies you might have and walk us through the path from you know low to mid single digit operating margins currently to perhaps low double digit margins longer term?

Speaker #4: Sure. Maybe the easiest way to think about that of course, the bigger driver in all of this is revenue. So we had envisioned on our basically historical profile of getting into that double digits right around the low 300s.

Tom Stanton: Sure. Maybe the easiest way to think about that. Of course, the bigger driver in all of this is revenue. We had envisioned on our basically historical profile of getting into that double digits right around the low $300s, say somewhere between $310 and $320. That assumes a gross margin in the 42% to 43%. That gross margin this quarter, and I will say it was this quarter, and I don't want to at all minimize the fact that it was low. We've had over 2 years, almost 3 years now, of raising gross margins pretty much every quarter or over any significant length of time. You can just see the trend moving upwards. Of course, that allows that revenue number to be lower.

Speaker #4: Say somewhere between 310 and 320. And that assumes a gross margin in the 42 to 43%. That gross margin this quarter and I will say it was this quarter.

Speaker #4: And I don't want to at all minimize the fact that it was low. But you know we've had over two years almost three years now of raising gross margins pretty much every quarter or you know over any significant length of time you can just see the trend moving upwards.

Speaker #4: And that's benefited us. And of course, that allows that revenue number to be lower when the numbers you know when I think about 310, 320, that's kind of in the midpoint of where our margin has been.

Tom Stanton: When I think about the $310, $320, that's kind of in the midpoint of where our margin has been. The environment is tougher, and really, the way that it impacted us this last quarter was it got rid of some of our flexibility. Well, we saw the decline in a large customer, and we had plenty of demand. The problem is the pluggables are really hot right now. Those are not high-margin products. We shipped a significant amount of those. We could've shipped a whole lot more if we had access to them. Some of the higher gross margin products were also just limited in supply. Our flexibility got impacted this quarter. I think that flexibility problem is not a fixed next quarter problem.

Speaker #4: But the environment is tougher. And really what that the way that it is that it impacted us this last quarter was it cut rid of some of our flexibility.

Speaker #4: So we saw the decline with our large customer which has got you know it's in the it's well, we saw the decline in a large customer.

Speaker #4: And we had plenty of demand. The problem is is you know the pluggables are really hot right now. Those are not high margin products.

Speaker #4: We shipped a significant amount of those. We could have shipped a whole lot more. If we had access to them. And some of the higher gross margin products were also just limited in supply.

Speaker #4: So our flexibility got impacted this quarter. I don't I think that flexibility problem is not a fixed next quarter problem. So we've kind of factored that into our numbers.

Tom Stanton: We've kind of factored that into our numbers. Now, what we're doing, one is we can, of course, raise prices. I don't want to over rotate on that knowing that there was a mix problem more so than anything else. We have already executed on our price increases, and we continue to keep our pricing in check with what we think the supply environment is going to be when those products ship. We'll continue to execute on that. We have started doing some redesigns, and that's just to give us more supplier flexibility. I think the gross margin piece is not the. I don't worry so much about gross margin because I don't think we're in a really bad place. I think we do have a mix issue. We need to make sure that we can continue supply no matter what happens.

Speaker #4: Now, what we're doing one is we can, of course, raise prices. I don't want to over kind of rotate on that. Knowing that the you know there was a mix problem more so than anything else.

Speaker #4: But we have already executed on our price increases and we continue to keep our pricing in check with what we think the supply environment is going to be when those products ship.

Speaker #4: So we'll continue to execute on that. We have started doing some redesigns. And that's just to give us more supplier flexibility. I think the gross margin piece is not the you know I don't worry so much about gross margin because I don't think we're in a really bad place.

Speaker #4: I think we do have a mix issue. But we need to make sure that we can continue supply no matter what happens. So we have kicked off redesigns in order to effectively mitigate supply issues which ultimately will improve gross margins.

Tom Stanton: We have kicked off redesigns in order to effectively mitigate supply issues, which ultimately will improve gross margins. As we had talked about maybe 1 year ago or so, we continue to move on reducing our OpEx in our COGS-related areas. We're seeing some benefit in gross margin, although it was hard to actually see through that this quarter. Did that answer your question?

Speaker #4: And then as we had talked about maybe a year ago or so we continue to move on reducing our opex in our COGS related areas.

Speaker #4: So we're seeing some benefit in gross margin although it was hard to actually see through that this quarter. Got it.

Irvin Liu: Got it. Thank you.

Speaker #1: Thank you. That did.

Tom Stanton: Okay.

Irvin Liu: That did.

Speaker #4: All right. Thank you.

Tom Stanton: All right. Thank you.

Speaker #2: And our next question comes from the line of Ryan Koontz with Needham and Company. Ryan, please go ahead.

Operator: Our next question comes from the line of Ryan Koontz with Needham & Company. Ryan, please go ahead.

Speaker #5: Great, thanks. Maybe just following up on the last question and your comment about supply impacts on higher gross margin products. I think we've all been assuming that memory has been a big concern.

Ryan Koontz: Great, thanks. Maybe just following up on the last question, and your comment about supply impacts on higher gross margin products. I think we've all been assuming that memory's been a big concern, mostly impacting the CPE side of the business, and maybe we saw some of that in the quarter with customers running inventory hotter or maybe even some pull forward before price increases that drove the big uptick in Q1. Maybe you can unpack the customer prem side gross margin trend as well as your comment around higher gross margin products that were impacted on supply. Thank you.

Speaker #5: Mostly impacting the CPE side of the business. And maybe we saw some of that in the quarter you know with customers running inventory hotter or maybe even some pull forward before price increases.

Speaker #5: That drove the big uptick in Q1. So maybe you can unpack the customer prem side gross margin trend as well as your comment around higher gross margin products that were impacted on supply.

Speaker #5: Thank you.

Speaker #4: Yeah. Sure. So it is more than memory. I hope I'm not the first one to tell you guys that. But it is definitely you know it has gotten tighter in other areas.

Tom Stanton: Yeah, sure. It is more than memory. I hope I'm not the first one to tell you guys that, but it has gotten tighter in other areas. Optical amplifiers are definitely tight. There are certain pieces of silicon that are fairly nebulous that are getting very tight. It is a broader base set of problems. There are some areas where even PC boards are getting tight. What's really important, the way that it impacts us is we still tend to book a lot of what we ship within the quarter. That ability to flex up for incremental demand, which we definitely saw this quarter, especially in optical. Our ability to flex up has really diminished, our forecasting is more important.

Speaker #4: Optical amplifiers are definitely tight. There are kind of certain pieces of silicon that are fairly nebulous that are getting very tight. So it is a broader based set of problems.

Speaker #4: There are some areas where, you know, even PC boards are getting tight. So, you know, what's really important—the way that it impacts us is we still tend to book a lot of what we ship within the quarter.

Speaker #4: And that ability to flex up for incremental demand which we definitely saw this quarter especially in optical. Our ability to flex up has really diminished.

Speaker #4: And so our forecasting is more important. But I would say the hardest thing at this point so I'm sure we've talked about in the past.

Tom Stanton: I would say the hardest thing at this point, I'm sure we've talked about in the past, memory was one of those things. I wasn't so much worried about the pricing of memory. I could pass a lot of that on. What I couldn't do, though, is make supply that wasn't there. It was all about getting memory. At least in our supply chain, memory today is not the biggest issue, right? There are issues that have eclipsed that, memory is, although incredibly expensive, that supply isn't as problematic as it was, let's say, six months ago or three months ago.

Speaker #4: Memory was one of those things I wasn't so much worried about the pricing of memory. I could pass a lot of that on. What I couldn't do though is make supply that wasn't there.

Speaker #4: So it was all about getting memory. At least in our supply chain, memory today is not the biggest issue, right? There are issues that now have eclipsed that, and memory, although incredibly expensive, that supply isn't as problematic as it was, let's say, six months ago.

Speaker #4: Or three months ago.

Speaker #5: Got it. That's really helpful.

Ryan Koontz: Got it. That's really helpful.

Tom Stanton: Okay.

Speaker #4: Okay.

Speaker #5: And then maybe to follow up on your comment around optical and the strength you're seeing in enterprise and cloud, what sort of use cases are you seeing there?

Ryan Koontz: Maybe as a follow-up, your comment around optical and the strength you're seeing in enterprise and cloud. What sort of use cases are you seeing there? Is this mostly for your line systems? You talked about pluggables. Can you give us any color on product mix there within the enterprise and cloud use cases would be really helpful. Thank you.

Speaker #5: Is this mostly for your line systems? You talked about pluggables. Can you give us any color on product mix there within the kind of enterprise and cloud use cases? That would be really helpful.

Speaker #5: Thank you.

Speaker #4: Yeah, so definitely on OLSS as well as, you know, just standard pluggables. I would say across the board it was high. I will tell you, OLSS for our line systems were a little more difficult to ship because of the constraints that we just talked about.

Tom Stanton: Yeah. Definitely on OLS as well as just standard pluggables. I would say across the board, it was high. I will tell you, OLS or our line systems were a little more difficult to ship because of the constraints that we just talked about. Pluggables is, generally speaking, upgrading of bandwidth, and as you know, we have some hyperscaler content there, and we're seeing a significant uptick in that activity as people are trying to upgrade their networks. I think it's all just about bandwidth increases, not so much footprint, but just bandwidth increases.

Speaker #4: Pluggables is generally speaking upgrading a bandwidth. And as you know we have some hyperscaler content there. And we're seeing kind of a you know significant uptick in that activity as people are trying to upgrade their networks.

Speaker #4: So I think it's all just about bandwidth increases – not so much about footprint, but just bandwidth increases.

Ryan Koontz: Got it. Really helpful. Thank you very much.

Speaker #5: Got it. Really helpful. Thank you very much.

Tom Stanton: Okay. All right.

Speaker #4: Okay. All right.

Operator: Our next question comes from the line of George Notter with Wolfe Research. George, please go ahead.

Speaker #2: Our next question comes from the line of George Snotter with Wolfe Research. George, please go ahead.

George Notter: Hi, guys. Thanks a lot. I was just trying to get a better sense for where you guys are on the balance sheet. I know there was some talk about the real estate transactions. Kind of wondering where you are on those. Any update would be great. Thanks.

Speaker #6: Hi guys. Thanks a lot. I was just trying to get a better sense for where you guys are on the balance sheet. I know there was some talk about the real estate transactions kind of wondering where you are on those.

Speaker #6: Any update would be great. Thanks.

Tom Stanton: Tim, you want to grab that?

Speaker #4: Tim, do you want to grab that?

Tim Santo: Yes, will do. Morning, George. The best news there is Huntsville is very hot. The first 600 or so individuals for Space Command will have seats in housing by the end of this year. We've seen a large uptick in military defense and other contracts being awarded to the Huntsville area, and that has driven up significantly the interest in our property. Beyond that, George, when we have something to announce, we will announce it. We're continuing to hold out for the best deal and the best opportunity for the company.

Speaker #3: Yes. Will do. Morning George. You know the best news there is Huntsville is very hot. The first 600 or so individuals for Space Command have will have seats in housing by the end of this year we've seen a large uptick in military defense and other contracts being awarded to the Huntsville area.

Speaker #3: And that has driven up significantly the interest in our property. Beyond that George when we have something to announce we will announce it. But you know we're continuing to hold out for the best deal and the best opportunity for the company.

Tom Stanton: Let me just add a little, because I also am very nervous about trying to pre-forecast something, but our showings on that property have gone up substantially over the last couple of months.

Speaker #4: Let me just add a little because I also am very nervous about trying to pre-forecast something. But our showings on that property have gone up substantially over the last couple of months.

Tim Santo: That's right.

Speaker #3: That's right.

George Notter: Great. Thank you.

Speaker #6: Great. Thank you.

Tom Stanton: All right.

Speaker #4: All right.

Operator: Our next question comes from the line of Bill Dezellem with Titan Capital. Bill, please go ahead.

Speaker #2: And our next question comes from the line of Bill Desalam with Titan Capital. Bill, please go ahead.

Bill Dezellem: Thank you. You put out a press release this morning relative to TOHKnet, and them beginning the trial. Would you talk a little bit about that? The spirit at which I ask this is I don't recall ADTRAN being in Japan historically, so provide some backdrop there if you would, please.

Speaker #3: Yeah, thank you. You put out a press release this morning relative to Tokenet and them beginning a trial. Would you talk a little bit about that? And the spirit in which I ask this is, I don't recall ADTRAN being in Japan historically.

Speaker #3: So, if you would, please provide some backdrop there.

Tom Stanton: Yeah, to be honest with you, I don't have that press release in front of me, but we do sell into Japan. This was in the optical space that we have sold for some period of time. I wish I did have that press release in front of me, Bill, but I don't.

Speaker #4: Yeah. To be honest with you, I don't have that press release in front of me. But we do sell into Japan, and this was, you know, in the optical space that we have sold for some period of time.

Speaker #4: And I wish I did have that press release in front of me, Bill, but I don't.

Tim Santo: We will add it momentarily.

Speaker #3: We'll have it momentarily.

Tom Stanton: Oh, okay. Yeah. There is also Japan is an interesting area because they were one of the first to build out GPON. The population base is pretty much covered. They are, I would say, leading the charge in moving to 50 gig. We have a lot of people that are trialing 50 gig and want to have marketing capabilities around 50 gig. I would say from a country perspective, Japan is probably at the forefront of literally looking at making that transition more wholesale. This is just that.

Speaker #4: Oh okay. Yeah. So that is there is also Japan is an interesting area because they were one of the first to build out GPON.

Speaker #4: And there are, you know, so the, you know, the population base is pretty much covered. And they are, I would say, leading the charge, as in moving to 50 gig.

Speaker #4: They're not you know we have a lot of people that are trialing 50 gig and want to have kind marketing you know capabilities around 50 gig.

Speaker #4: I would say from a country perspective Japan is probably the at the forefront of literally looking at making that transition more wholesale. So and this is just this is just that.

Bill Dezellem: Great. Thank you. Relative to the supply issues and the customer schedule adjustment, how does all of this affect 2027? I guess another way to ask that is, the H2 of 2026, is that a long enough period to adjust component supply chain and make these various adjustments that you need to be back on track? Is this a longer sort of adjustment period?

Speaker #3: Yeah, great. Thank you. And then, relative to the supply issues and the customer schedule adjustment, how does all of this affect 2027? I guess another way to ask that is: is the second half of '26 a long enough period to adjust component supply chain?

Speaker #3: And make these various adjustments that you need to be back on track? Or is this a longer sort of adjustment period?

Tom Stanton: Let me answer that a couple different ways, and I'll try to be as direct as I can. One is the root cause of the situation was really born from a dynamic within a particular customer, which we think will be worked out before the end of the year. If it weren't for that route, we would not be talking about this. It did highlight, in going through the quarter, once that effect kind of permutated through the company, it did highlight the fact that flexibility within the rest of the product set is getting tighter and tighter. I want to first put it in the right frame. I don't see that tightness going away in the near term.

Speaker #4: Let me answer that a couple of different ways, and I'll try to be as direct as I can. So, one is, you know, the root cause of the situation was really born from a dynamic within a particular customer, which we think will be worked out before the end of the year.

Speaker #4: So if it weren't for that root we would not be talking about this. But then it did highlight in going through the quarter once that effect kind of permeated through the company it did highlight the fact that flexibility within the rest of the product set is getting tighter and tighter.

Speaker #4: So I want to first you know put it in the right frame. I don't see that tightness going away in the near term. I do know and probably many people on this call know that there is talk about additional capacity especially in the higher nanometer process which is kind of where our products are.

Tom Stanton: I do know, and probably many people on this call know, that there is talk about additional capacity, especially in the higher nanometer process, which is kind of where our products are, let's say 12 and up, coming online next year, which would alleviate some of these issues that we're talking about. I think we're just in a tighter supply chain environment. The best way for us to be able to mitigate that tightness is literally just better forecast, more order coverage. I preach that to our customers every time I can. You need to get your orders in, right? We need to be able to have visibility to it, and we need to secure supply. I do think the customers are getting. It's amazing. It's taken a long time, but I do think customers are getting it.

Speaker #4: Let's say 12 and up coming online next year, which would alleviate some of these issues that we're talking about. But I think we're just in a tight supply chain environment.

Speaker #4: And the best way for us to be able to mitigate that tightness is literally just better forecast more order coverage. And you know I've preached that to our customers every time I can.

Speaker #4: You need to get your orders in. Right? We need to be able to have visibility to it. And we need to secure supply. And I do think the customers are getting it's amazing.

Speaker #4: It's taken a long time, but I do think customers are getting it. But I can tell you what, it might mitigate a particular chip today.

Tom Stanton: I can tell you what would mitigate a particular chip today, but I can tell you it'll be a different chip or a different problem six months from now. I just think we're living in a tight period right now, and I can't tell you it's going to disappear next year. What quarter it would disappear if it does disappear next year. I think it's all about discipline with internally. We have, as we've talked about, we've gotten some more key components in our inventories now to make sure that we can mitigate the problems that are known. Like this quarter, there was issues that were not an issue last quarter, right? We have to get better at forecasting where those future issues will be, not just the ones that we're currently facing.

Speaker #4: But I can tell you, there'll be a different chip or a different problem six months from now. So I just think we're living in a tight period right now.

Speaker #4: And I can't tell you it's going to disappear next year, or, you know, in, you know, what quarter it would disappear if it does disappear next year.

Speaker #4: I think it's all about discipline within internally. We have as we've talked about you know we've gotten some more key inventories now to make sure that we can mitigate the problems that are known.

Speaker #4: But like this quarter there was issues that were not an issue last quarter. Right? So we have to get better at forecasting where those future issues will be not just the ones that we're currently facing.

Tom Stanton: That's not a good answer, but that's kind of the environment we're in.

Speaker #4: So, that's not a good answer, but that's kind of the environment we're in.

Bill Dezellem: No, that is helpful. I'll ask one more question before I hop off, Tom. Does that imply that we should anticipate you all kind of building extra inventory in certain areas so that you can adjust that flexibility, not with your supply chain, the product mix flexibility, not through the supply chain as much as just through your own warehouse, for lack of a better phrase?

Speaker #3: Yeah. That is helpful. And so I'll ask one more question before I hop off Tom. Does that imply that we should anticipate you all kind of building extra inventory in certain areas so that you can adjust that flexibility not with your supply chain your product the product mix flexibility not through the supply chain as much as just through your own through your own warehouse for lack of a better phrase?

Tom Stanton: Yeah. It does imply that, and I will tell you that has been happening already. You just haven't seen it so much. The reason is we've been able to draw down old inventory back from the supply chain crisis, down to a point to where we're kind of mitigating that increase. You can think about it as old inventory versus new inventory, and that new inventory is directly related. Our inventories would be going down more if we weren't adding these kind of key components. At some point in time, that old inventory's going to not be so old anymore, and you'll see an uptick in that inventory. I don't think it'll be material to the numbers.

Speaker #4: Yeah. It does imply that. And I will tell you that that that has been happening already. You just haven't seen it so much. And the reason is is we've been able to draw down old inventory back in the from the supply chain crisis.

Speaker #4: Down to a point where we're kind of mitigating that increase. But you can think about it as old inventory versus new inventory. And that new inventory is directly related—our inventories would be going down more if we weren't adding these kind of key components.

Speaker #4: But at some point in time, that old inventory is going to not be so old anymore, and you'll see an uptick in that inventory.

Speaker #4: But I don't think that's—I don't think it'll be material to the numbers.

Bill Dezellem: Great. Thank you for taking all the questions.

Speaker #3: Great. Thank you for taking all the questions.

Tom Stanton: Sure.

Speaker #4: Sure.

Operator: Our next question comes from the line of Dave Kang with B. Riley Securities. Dave, please go ahead.

Speaker #1: All right. Next question comes from the line of Dave Gang with B. Riley Securities. Dave please go ahead.

Dave Kang: Good morning. Thank you. First question is, wondering if you can provide what the book-to-bill was and more interested in optical book-to-bill, if you can provide those.

Speaker #5: Good morning. Thank you. First question is wondering if you can provide what the book to bill was and more interested in optical book to bill if you can provide those.

Tom Stanton: We really don't do book-to-bill as a metric that we actually publish. I will tell you, optical was probably the strongest area, and let's just say all the numbers were either at one or above one.

Speaker #4: We really don't do book to bill as a as a metric that we actually publish. It was I will tell you optical was probably the I'm guessing here.

Speaker #4: But probably the strongest area. And it was let's just say all the numbers were either at one or above one.

Dave Kang: Got it. Regarding the revenue miss, obviously it was a project delay, but sounds like if you had enough components that you would've made up that revenue. Was that the message? Basically, you're saying that

Speaker #5: Got it. And then regarding the revenue miss obviously it was a project delay. But sounds like if you had enough components that you would have made up that revenue was that the message?

Tom Stanton: Yes

Dave Kang: demand is so strong that it would've made up that $12 million revenue shortfall if you had enough components.

Speaker #4: Yes.

Speaker #5: Demand is so strong that it would have made up that 12 million revenue shortfall if you had enough components?

Tom Stanton: Yes, without a doubt. No hesitation at all. If we had plenty of material, we would not be talking about the downtick.

Speaker #4: Yes. Without a doubt. I mean no hesitation at all. If we had if we had plenty of material we that we would not be talking about the downtick.

Dave Kang: What about the current Q3? Can you talk about that project delay, where you are, also, you talked quite a bit about supply situation, but how that's going to play out in Q3. Obviously, we're looking for sort of a flattish quarter sequentially.

Speaker #5: And what about the current third Basically you're saying that. quarter? Can you talk about that project delay where you are and also I mean you talked quite a bit about supply situation.

Speaker #5: But how that's going to play out in third quarter. Obviously we're looking for sort of a flattish quarter sequentially.

Tom Stanton: Yeah. We don't see an uptick in the customer that we're talking about right now. To be honest with you, we just don't see a change in the procurement environment. We think things are going to stay in the kind of status quo that they're in right now, maybe even get a little bit tighter in certain areas. We are fighting for more supply. Literally, we have people calling every day trying to get more of whatever it is that we have on order or don't have on order. That's just kind of seeing through that mix of what's going to be available and what's not going to be available is kind of what our forecasting process has turned into. Yeah, it's just assuming the environment doesn't change.

Speaker #4: Yeah. So we don't see an uptick in the customer that we're talking about right now. And to be honest with you we just don't see a change in the procurement environment.

Speaker #4: So, we think things are going to, you know, stay in the kind of status quo that they're in right now—maybe even get a little bit tighter in certain areas.

Speaker #4: We are fighting for more supply. I mean literally calling we have people calling every day trying to get more of whatever it is that we have on order or don't have on order.

Speaker #4: So that's just kind of seeing through that that mix of what's going to be available and what's not going to be available is kind of what our forecasting process has turned into.

Speaker #4: And so yeah it's just assuming the environment doesn't change.

Dave Kang: Well, I think, I was juggling a couple of things. Obviously, you've seen that this FCC planning to ban Chinese transceivers. Just wondering if you were sourcing transceivers or pluggables from Chinese vendors, and if so, how quickly can you pivot to American vendors?

Speaker #5: Well, I think, you know, I was juggling a couple of things. Obviously, you've seen that the FCC is planning to ban Chinese transceivers. Just wondering if you were sourcing transceivers or pluggables from Chinese vendors, and if so, how quickly can you pivot to American vendors?

Tom Stanton: We do some pluggables from China. Let's say, transceivers from China. We also source from other places, and I don't know. I'm not versed enough to give you a direct answer to that. That's something that we can cover at, you can call in, and we can talk more about it.

Speaker #4: We do do some pluggables from China. Let's say transceivers from China. We also source some other places. And I don't know I'm not versed enough to give you a direct answer to that.

Speaker #4: So, that's something that we can cover at—you know, you can call in and we can talk more about it. But—

Dave Kang: Yeah

Tom Stanton: Give me a call back.

Dave Kang: It's clearly a fluid situation. I'm sure there are really a lot of questions there. My last question is, any update on LPO activities? Any qualification?

Speaker #5: Yeah. It's clearly a fluid situation. I'm sure there are a lot of questions there. My last question is any update on LPO activities? Any qualification or yeah.

Tom Stanton: Yeah.

Dave Kang: Yeah.

Tom Stanton: Well, it's still we're not talking about qualification yet. It is still on track. As I talked about before, why we would get units in right around the half or Q2, get them to customers. We do have another piece to this, which we haven't really talked much about, which is the MicroMux Quattro. We've got multiple customers, including multiple hyperscalers that are very interested in that product as well. That one actually delivers earlier, so I would expect to see trial units before, let's say, sometime in Q1. We have people right now that are trialing kind of alpha units, and that seems to be going well. I think both of those are on track, but both of those are getting some traction. That seems to be going well.

Speaker #4: Well it's still we're not talking about qualification yet. It is still on track as I talked about before. Right? We would get units in right around the half or you know second quarter.

Speaker #4: Get them to customers. We do have a significant I will tell you another piece of this which we haven't really talked much about which is the Quattro.

Speaker #4: And we've got multiple customers including multiple hyperscalers that are very interested in that product as well. That one actually delivers earlier. So I would expect to see trial units before let's say sometime in the first quarter.

Speaker #4: We have people right now that are trialing kind of alpha units and and that seems to be going well. So I think both of those both of them are on track.

Speaker #4: But both of those are are getting some traction. So that seems to be going well.

Dave Kang: Thank you.

Speaker #5: Thank you.

Tom Stanton: Okay.

Speaker #4: Okay.

Operator: Our next question comes from the line of Tim, sorry about that, Tim Savageaux with Northland Capital Markets. Tim, please go ahead.

Speaker #1: All right. Next question comes from the line of Tim Evaso with North Capital Markets. Tim, please go ahead.

Tim Savageaux: Yeah. Hey, good morning. I think you mentioned a growth metric around the cloud portion. Talked about 25% of revenue being from government enterprise. I think it was something in the 90s in terms of cloud growth. I just want to go back and confirm that and also try to get a sense of within that 25% of revenue, how large is the cloud piece? I'll follow up from there.

Speaker #6: Yeah. Hey. Good morning. You mentioned a growth metric around the the cloud portion talked about 25% of revenue being from government enterprise. I think it was something in the 90s in terms of cloud growth.

Speaker #6: I just want to go back and and confirm that. And also try to get a sense of you know with you know within that 25% of revenue how how how large is the the cloud piece and I'll follow up from there.

Tom Stanton: Yeah. Let me see if I have that. I don't think I have the number, but I do kind of generally know where we are in that space. The specific number that we gave was, I think it was 97% growth in hyperscalers. We look at cloud as being broader than hyperscalers because that would include typically large content cloud providers. Hyperscalers specifically, was 97%. That's not a surprise. I think we kind of signaled in our last call that that area we expected to be solid this year and continue to grow, and that seems to be the case. What was the second part of your question, Tim?

Speaker #4: Yeah. Let me see if I have that. I don't think I have the number. But I I do kind of generally know where we are in that space.

Speaker #4: So the specific number that we gave was I think it was 97% growth in hyperscalers. And so we look at cloud as being broader than hyperscalers because that would include typically large content cloud providers.

Speaker #4: So hyperscalers specifically was 90 97%. And and that's not a surprise. I mean we we I think we kind of signaled in our last call that that area we expected to be solid this year and continue to grow and it's it seems to be that that seems to be the case.

Speaker #4: And what was the second part of your question Tim?

Tim Savageaux: I was just trying to get a sense of within that category.

Tim Savageaux: I was just trying to get a sense of within that category. However you want to describe it, how significant is that? I assume that's a relatively small percent of that 25%.

Speaker #6: I was just trying to get a sense of, you know, within that category—however you want to describe it—how significant is that.

Tim Savageaux: However you want to describe it, how significant is that? I assume that's a relatively small percent of that 25%.

Speaker #6: I assume that's a relatively small percent of that 25%—you know, of the broader category. But—

Tom Stanton: No, it's not.

Tim Savageaux: of the broader category.

Tom Stanton: It's not. My sense, and just from remembering, is it's somewhere between 30% and 50%. It's getting to be a big piece of that pie.

Speaker #4: It's not. It's it's my sense and just from remembering is it's somewhere between 30 and 50 percent. It it it's getting to be a big piece of that that pie.

Tim Savageaux: Of that 25%.

Tom Stanton: Of that 25%.

Speaker #6: Of that of that 25%.

Tim Savageaux: Okay. Excellent. Yep. No, I got it. Just a quick one, any 10% customers in the quarter? Also, as you look out to the Q3 guide, I'd be interested in what's happening there from a segment perspective. It sounds like you don't expect access and aggregation to rebound given the customer push

Speaker #4: Okay.

Speaker #6: Excellent. Yeah. No. I I got it. And just a quick one. Any 10% customers in the quarter and also as you look out to the Q3 guide I'd be interested in what's happening there from a segment perspective.

Speaker #6: It sounds like you don't expect Access and Aggregation to rebound given the customer push, and then you've got a little sequential growth there. I mean, I guess the overall question is: do you expect to see Optical continue to grow?

Tim Savageaux: You've got a little sequential growth there. I guess the overall question is, do you expect to see optical continue to grow?

Tom Stanton: Yes. Direct answer is absolutely yes. I talked a little bit about the order flow there, and yes. We expect that to grow. Subscriber is one of those that's probably the most difficult thing to forecast, because it is very much demand driven, and people buy chunks of inventory, and then they go away for a while. You'll always see more volatility, I'll say typically see more volatility in that subscriber piece. That one's less firm in our numbers in knowing exactly where it's going to end up. Access and agg, you're right. We don't expect a rebound because that single customer is such a large piece of that content. I will tell you that access and agg in Europe, notwithstanding that customer, was actually pretty strong, and we continue to expect that strength in the Q3. Optical is going to be the biggest.

Speaker #4: Yes. Direct answer is absolutely yes. I mean I talked a little bit about the order flow there and yes. So I mean that's we we expect that to grow.

Speaker #4: You know subscriber is one of those that's probably the most difficult thing to forecast because it is very much demand driven and people buy chunks of inventory and then they go away for a while.

Speaker #4: So you'll see you'll always see more volatility. I'll say typically see more volatility. And that subscriber piece. So that one's less firm in our numbers in knowing exactly where it's going to end up.

Speaker #4: Access and ag you're right. We don't expect a rebound because that single customer is such a large piece of that content. I I will tell you that that access and ag in Europe notwithstanding that customer was actually pretty strong and we continue to expect that strength in the third quarter.

Speaker #4: But optical is going to be the big, the big—and I can confirm there were no 10% customers this quarter.

Tom Stanton: I can confirm there were no 10% customers this quarter.

Tim Savageaux: Great. Thanks very much.

Speaker #6: Great. Thanks very much.

Tom Stanton: Okay.

Speaker #4: Okay.

Operator: Our next question comes from the line of Michael Genovese with Rosenblatt Securities. Michael, please go ahead.

Speaker #1: All right. Next question comes from the line of Michael Genovese with Rosenblatt Securities. Michael, please go ahead.

Mike Genovese: Thanks. Hey, Tom. I want to ask more about pluggables. I want to clarify a couple things on the call. When you mentioned the mix shift earlier, and that you were selling more pluggables, could you just talk about what business specifically that was in, and what kind of pluggables, and selling more pluggables as opposed to, I guess, embedded systems in optical? For DCI and long haul in metro, is that what you were talking about?

Michael Genovese: Thanks. Hey, Tom. I want to ask more about pluggables. I want to clarify a couple things on the call. When you mentioned the mix shift earlier, and that you were selling more pluggables, could you just talk about what business specifically that was in, and what kind of pluggables, and selling more pluggables as opposed to, I guess, embedded systems in optical? For DCI and long haul in metro, is that what you were talking about?

Speaker #7: Oh. Thanks. Hey Tom. I I want to ask more about about pluggables. So I want to clarify a couple things on the call. When you mentioned the mix shift earlier and that you were selling more pluggables could you just talk about what business specifically that was in and and what which what kind of pluggables and selling more pluggables as opposed to I guess embedded systems and optical.

Speaker #7: Is that you know for for for for DCI and long haul and Metro is that is that what you were talking about?

Tom Stanton: Yes, more specifically, I will tell you, we probably had the strongest 100ZR quarter we've ever had. That should tell you kind of what we're talking about.

Speaker #4: Yes. But you know more more specifically I will tell you we probably had the strongest 100 ZR quarter we've ever had. So that you know that that should tell you kind of what we're talking about.

Mike Genovese: Okay. That makes sense. You've just mentioned earlier the quad, because we were asking about the LPO product, which I think has a different name. The quad, could you talk more about the difference between those two products?

Michael Genovese: Okay. That makes sense. You've just mentioned earlier the quad, because we were asking about the LPO product, which I think has a different name. The quad, could you talk more about the difference between those two products?

Speaker #7: Okay. That makes sense. And then you've just mentioned earlier the quad. You know because we were you know I guess asking about the the LPO product which I think has a different name.

Speaker #7: And then the quad—could you talk more about the difference between those two products?

Tom Stanton: Yeah. The other product that we were talking about that got a lot of press was the LiteWave800.

Speaker #4: Yeah. So the the the other product that we're talking about that got a lot of press was the LightWave 800. The quad is actually a 4x100.

Mike Genovese: Yes.

Michael Genovese: Yes.

Tom Stanton: The quad is actually a 4 by 100. It's in the MicroMux family, it's a 4 by 100 mux that's very efficient. I don't know if there's anything out on the market today that's like that. It plugs right into a router and gives you multiplexing capability at a very low cost.

Speaker #4: It's in the MicroMux family, so it's a 4x100 MUX. That's very, very efficient. I don't know if there's anything out on the market today that's like that.

Speaker #4: So you know plugs right into a router and gives you multiplexing capability at a very low cost.

Mike Genovese: Okay. Sorry. If I'm not mistaken, though, the LiteWave800 is different from these products because it's a new market of inside the data center for you, as opposed to between data centers where most of your business is now. Is that a correct understanding?

Speaker #7: So so so if I'm okay. Sorry. Sorry. If if I'm not mistaken though the the LightWave 800 is is different from these products because it's a new market of inside the data center for you as opposed to you know between data centers where most of your business is now.

Michael Genovese: Okay. Sorry. If I'm not mistaken, though, the LiteWave800 is different from these products because it's a new market of inside the data center for you, as opposed to between data centers where most of your business is now. Is that a correct understanding?

Speaker #7: Is that is that a correct you know is that a correct understanding?

Tom Stanton: Yes. The LiteWave800 is intra data center, which we have not played in that space. We don't have a MicroMux product either, by the way. Both of these are kind of incremental to the piece that we have traditionally done. I would say the LiteWave is a farther reach, yes.

Speaker #4: Yes. That that's the LightWave 800 is is intra data center which yeah we we have not played in that space. We don't have a MicroMux product either by the way.

Speaker #4: I mean so both of these are kind of incremental to the piece that we have traditionally done. But I would say Mic the LightWave is a is a farther reach.

Speaker #4: Yes.

Mike Genovese: Okay. The timing, though, is the MicroMux is earlier in 2027, and the LiteWave is mid 2027. Is that correct?

Michael Genovese: Okay. The timing, though, is the MicroMux is earlier in 2027, and the LiteWave is mid 2027. Is that correct?

Speaker #7: Okay. And and the timing though is the MicroMux is earlier in '27 and the LightWave is mid '27. Is that is that correct?

Tom Stanton: The MicroMux is going to be out earlier. We should be trialing units end of this year or early next year. The current schedule for the LiteWave is getting units trialing middle of next year. We're saying into Q2. Production towards the end of the year or the first part of the following year.

Speaker #4: The the MicroMux is going to be out earlier. So I would with our we should be trialing units end of this year or early next year.

Speaker #4: And then the current the current schedule for the LightWave is getting units trialing middle of next year you know we're saying into Q2. And then production towards the end of the year of the first part of the following year.

Mike Genovese: Okay, great. Just the final question from me. I guess maybe it's a two-part question. With the transceivers for inside the data center, this is a very large market, right? It's a new TAM that you're going into, I'm kind of used to seeing deals there being like you don't get 25 or even $50 million deals. Every time I see somebody win a transceiver deal, it's at least $100 million, and it could be $1 billion. I'm just wondering if the larger deal sizes, as you start to work on that market, make sense to you, if that sounds reasonable.

Michael Genovese: Okay, great. Just the final question from me. I guess maybe it's a two-part question. With the transceivers for inside the data center, this is a very large market, right? It's a new TAM that you're going into, I'm kind of used to seeing deals there being like you don't get 25 or even $50 million deals. Every time I see somebody win a transceiver deal, it's at least $100 million, and it could be $1 billion. I'm just wondering if the larger deal sizes, as you start to work on that market, make sense to you, if that sounds reasonable.

Speaker #7: Okay. Great. And then that just the final question from me. I guess maybe it's a two part question. But you know with the transceivers for inside the data center you know this is a very large market right.

Speaker #7: It's a new TAM that you're going into. And I'm I'm kind of used to seeing deals there being you know like you don't get 25 or even 50 million dollar deals.

Speaker #7: You know, every time I see somebody win a transceiver deal, it's at least $100 million and it could be a billion. You know, I'm just wondering if the larger deal sizes, as you start to work on that market, make sense to you.

Speaker #7: If that if that if that if that sounds reasonable. And and then just you know your ability to sell into that market and to have a sales force that that interacts with that side of the customer and and to kind of you know it's a big TAM but basically you're the confidence of ADTRAN that they can execute in that market from a sales and market I mean the product specs look great.

Mike Genovese: Just your ability to sell into that market and to have a sales force that interacts with that side of the customer and to kind of. It's a big TAM, but basically the confidence of Adtran that they can execute in that market from a sales and mark. I mean, the product specs look great. If we can assume you can make the product, are you confident that you can sell the product?

Michael Genovese: Just your ability to sell into that market and to have a sales force that interacts with that side of the customer and to kind of. It's a big TAM, but basically the confidence of Adtran that they can execute in that market from a sales and mark. I mean, the product specs look great. If we can assume you can make the product, are you confident that you can sell the product?

Speaker #7: But if we can assume you can make the product, are you confident that you can sell the product?

Tom Stanton: Yeah. Michael, you may not. We sell to most of these customers already. Now we sell different products. Most of them have. For instance, like I mentioned before, hyperscaler was the fastest growing area in our enterprise segment. It was a significant contributor. They know who we are. I would say without a doubt. We've even sold access products to one of the hyperscalers that was really into access. They know who we are. I don't think there's a trust problem with thinking that we can scale and that we build quality products. We have increased our sales force into that area to make sure that we're covering all of the bases. We've already done that. We're trying to get all the pieces in the right place.

Speaker #4: Yeah. So so Michael you may not we sell to most of these customers already. Now we sell different products. But most of them have you know for instance like like I mentioned before hyperscaler was the fastest growing area in our enterprise segment.

Speaker #4: And he was a significant contributor. So they know who we are. I would say without a doubt you know we've even sold access products to one of the hyperscalers that was really into access.

Speaker #4: So, they know who we are. I don't think there's a trust problem with believing that we can scale and that we build quality products.

Speaker #4: We have increased our sales force into that area to make sure that we're covering all of the bases. We've already done that. We're trying to get all the pieces in the right place.

Tom Stanton: It's not like they won't have heard of us, and I doubt if there'd be any issue with worries about scalability with us. In relation to the numbers that you're talking about, you are correct. I think my job is to not get us too overhung out there. We need to be able to deliver what we need to be able to deliver, but the numbers are typically bigger than the numbers that we're talking about.

Speaker #4: It's not like they won't have heard us. And I doubt if there’d be any issue with worries about scalability with us. In relation to the numbers that you're talking about, you are correct.

Speaker #4: I think my job is to not get us too over-extended out there. We need to be able to deliver what we need to deliver.

Speaker #4: But the numbers are typically bigger than the numbers that we're talking about.

Mike Genovese: Great. Okay. Thanks so much. Appreciate it.
