Earnings Call Speaker Segments
Operator
operatorGreetings, everyone, and welcome to the Calix Second Quarter 2026 Earnings Conference Call. [Operator Instructions] As a reminder, this conference is being recorded. It is now my pleasure to introduce your host, Nancy Fazioli, Vice President, Investor Relations. Nancy, please go ahead.
Nancy Fazioli
executiveThank you, Darryl, and good morning, everyone. Thank you for joining our second quarter 2026 earnings call. Today on the call, we have President and CEO, Michael Weening; and Chief Financial Officer, Cory Sindelar. As a reminder, today, after the market closed, Calyx issued a news release, which was furnished on a Form 8-K, along with our stockholder letter and is also posted in the Investor Relations section of the Calix website. Today's conference call will be available for webcast replay in the Investor Relations section of our website. Before I turn the call over to Michael for his opening remarks, I want to remind every -- but on this call, we will refer to forward-looking statements, including all statements the company will make about future financial and operating performance, growth strategy and market outlook, and that actual results may differ materially from those contemplated by these forward-looking statements. Factors that could cause actual results and trends to differ materially are set forth in the second quarter 2026 letter to stockholders and the annual and quarterly reports filed with the SEC. Calix assumes no obligation to update any forward-looking statements, which speak only as to their respective dates. Also on this conference call, we will discuss both GAAP and non-GAAP financial measures. A reconciliation of GAAP to non-GAAP measures is included in the second quarter 2026 letter to stockholders that was posted yesterday. Unless otherwise stated, all financial information referenced in this call that will be non-GAAP. With that, Michael, please go ahead.
Michael Weening
executiveThank you, Nancy. Much like the dot-com revolution before, the AI revolution is changing our society functions and will transform business model in every industry. The key difference between the dot-com era and the AI is a racing -- the AI rate of change is unprecedented, and those who move fast will lead the industries they serve. The second quarter was the beginning of Calix, the AI leader. -- as we began realizing the value of our 15-year investment through the first full quarter of our AI mated Calix platform being live. . Calix is access to data, insights and the ability to autonomously or through team member augmentation improve operations, marketing, support and subscriber experiences for our service provider customers regardless of size. These expanding Calix 1 capabilities to enable our customers to address the threat of broadband commoditization through differential experiences resulting in winning new subscribers growing revenue, higher retention across consumer, business, MDU and the medical segments they serve, while improving operating costs with a predictable implementation of AI capabilities. Customer interest in Calix exploded in Q2, driving record RPLs, record software and services revenue, while the strength of the platform was evidenced by the significant jump in software and service margin as we had all customers live. We also tripled the number of customers that signed up for agent workforce cloud. More important is the makeup of those customers. They were not only the invaders. We partner with Calix early in the product life cycle and are committed to the value that can be realized in their business model by being first to market -- the customers who signed up in Q2 span the entire adoption life cycle from early adopter, which is expected to late majority, which signals a significant Agent Workforce cloud-enabled ship across our base. The shift is that every business leader knows they must have in the strategy or they will be at risk. The late majority adoption crude that Calix 1 is a secure, trusted and predictable approach for every customer to adopt AR. It is secure and trusted as we have invested [indiscernible] years into the platform and domain now to meet our customers' needs. Since November 2023, we have evolved the platform to be AI native while ensuring that our processes, culture, security and governance expanded to meet the needs of the AI era for our customers. It is predictable as our AI native platform architecture allows us to use any AI model and is our belief that hardened open service models meet our workflow, use case and industry needs. That means Calix for the largest issue that is raging across all industries. How do you use AI predictably as one cannot calculate an ROI on a cost that can quickly run out of control. In our architecture, we have a true tokens through hardened open serve AR models and the acquisition of Pure Compute. Paliton customers are adopting a platform that delivers AI capabilities that can be trusted are secure and are offered at a predictable cost which will yield an that will grow every month with their subscription as we acquire new subscribers a low revenue, reduced churn and lower operating costs through the power of Calix agent workforce cloud. At Investor Day, I shared a slide that showed our rate of innovation. On the first generation of our platform, our annual feature rate peaked at 181 in 2018. Our second-generation platform featured sorry, our second-generation platform feature rate, PD18 in 2024. With the third generation of our platform launched, our customers can expect that our past innovation velocity will be quickly suppressed with Agent Workforce filing, which brings me to the Calix team. This team continues to win awards as one of the best cultures in any industry. Having outlined a subset of awards in the investor letter, including Fortune recognizing Calix and the 100 Best Companies to Work -- for list. The strength of this culture has never been more important. While AI is a powerful technology, it requires teams to get the most of it. Our customer success organization will help our customers leverage agent workforce cloud to transform and inside Calix, our leaders are taking a human-centric approach to AI to ensure that Calix transforms internally by understanding how we work so that we can identify those portions of our business that will benefit from it. We are using AI to gain operating leverage across Calix. In summary, we are committed to transforming our customers and ourselves through the power of AI. With that, I'll turn it to Cory to cover the details of an amazing quarter. Clark?
Cory Sindelar
executiveThank you, Michael. We saw continued strong and broad-based demand in the second quarter, delivering record revenue of $293 million, a 5% sequential increase and 21% year-over-year growth, exceeding our guidance range. Importantly, this quarter, we experienced a return to strong software growth. Service and -- software and service revenue grew to a record $50 million, up 7% sequentially and 16% year-over-year. as customers began to realize value from Agentic workflows on Calix One. Last quarter was the completion of our platform migration -- we set our focus with pivot to identifying our BSP customers, and RPOs would accelerate...
Unknown Executive
executiveSorry, Cory, can I please cause you. Daryl, on this operator, I understand from some of the people on the call that the call has been dropping. Could you please come on and let us know if we should restart.the call.
Unknown Executive
executiveI am here, and I have heard everything thus far.
Unknown Executive
executiveOkay. Apparently those who are participating by webcast or having the portions of the call that dropped. And I'm wondering if we should start the call once again.
Unknown Executive
executiveI can confirm as well the webcast has been stable. And I've been spot checking and I have heard as well through the webcast.
Unknown Executive
executiveOkay. So you can confirm that the webcast is acceptable and there are no issues on -- for the listeners?
Unknown Executive
executiveAs far as I can tell, there are no issues.
Unknown Executive
executiveOkay. Pala, Corey, you can go ahead with where you are continuing.
Cory Sindelar
executiveImportantly, this quarter, we experienced a return to strong software growth. Software and service revenue grew to a record $50 million, up 7% sequentially and 16% year-over-year as customers began to realize value from agent workflows on Calix One. Last quarter, with the completion of our platform migration, we set our focus with pivot to identifying our BSP customers and RPOs would accelerate in the second half of 2026, Our customers moved faster than anticipated as we saw record RPOs of $386 million, up 3% sequentially and 11% year-over-year. . Current RPOs were $162 million, up 3% sequentially and 21% year-over-year. Based on the strong momentum exiting the second quarter, we continue to expect RPO growth to accelerate in the second half of the year as we deliver additional identic workflows and demonstrate the value of Calix One. Furthermore, as we discussed last quarter, we would be running on a single cloud infrastructure this quarter. As such, having garnered the corresponding cost reduction, -- and when combined with the Gentek platform-driven demand, we yielded an 810 basis point sequential improvement in non-GAAP software and service gross margin. And to give you a sense of the continued leverage in the model. I will break the precedent and say that we expect software and service gross margin to set a new record in the third quarter. As the AI leader in the broadband space, we are also focused on being the leader in human-centric AI deployment inside our own company. We've demonstrated meaningful operating leverage in the second quarter of 2026. Non-GAAP operating expenses were approximately $122 million or 42% of revenue, down from 45% and in the prior quarter, reflecting both leverage in our growth model and early productivity gains from our human-centric AI investments as well as lower incentive compensation and timing of certain expenses. Turning to appliances. Appliance revenue was a record $243 million, a 4% increase sequentially and a 23% increase year-over-year. Non-GAAP appliance gross margin was 52.9%, representing a decrease of 460 basis points sequentially and 170 basis points year-over-year due to higher memory costs, which was partially offset by memory surcharges. As a result of the above, non-GAAP net income was $31 million or $0.47 per diluted share, above our guidance range. and we generated free cash flow of approximately $12 million. Our balance sheet remains strong. We ended the quarter with cash and investments totaling $194 million after deploying $69 million to repurchase 1.6 million shares. DSO was 42 days, and inventory turns were 2.7%, reflecting deliberate investments in inventory to secure supply and meet continued strong demand. Turning to guidance. For the third quarter of 2026, we expect revenue between $301 million and $307 million, up 4% at the midpoint over the prior quarter. This reflects continued strong broad-based demand even as customers are more tightly managing their own inventory in response to higher memory costs. For 2026, we expect annual revenue to grow at the higher end of the 15% to 20% growth range provided last quarter. Our third quarter non-GAAP gross margin guidance is 2% at the midpoint reflecting higher memory cost impact. As we navigate this industry-wide exogenous event, we remain focused on supply to ensure our customers can continue to meet strong subscriber demand. while we maintain a footprint aggressive stance. As you are well aware, there are many inflationary cost pressures across all industries. In our space, memory costs represents the most extreme of these pressures. As we partner with our customers on surcharges, they value certainty. Certainty on the costs and most importantly, certainty of supply. Our surcharge program is structured to deliver exactly that with the goal to recover the incremental memory costs without adding profit. This means over the long run, memory surcharges will be gross profit neutral while remaining a headwind to gross margin. Given the implementation of our memory surcharge program, we expect appliance gross margin will bottom in the third quarter of 2026. The third quarter of non-GAAP operating expense guidance is $124.5 million at the midpoint, a sequential increase driven primarily by the timing of expense and higher incentive compensation, partly offset by continued productivity gains from our human-centric AI investments. Michael, back to you.
Michael Weening
executiveThanks, Cory. . And last year, there's been much debate about AI agents and the effect it will have on customers and the markets they serve. We believe that Calix is uniquely positioned to take advantage of the AI market opportunity in the broadband market based on our 15-year investment in the Calix platform and our work since November of 2023 to evolve the platform and our processes for the opportunity ahead. Our customers all know they need AI, and we are best placed to deliver subscriber or revenue growth, churn reduction and cost improvements with Agent Workforce Cloud in a trusted secure and predictable way. predictability of AI cost is the biggest issue gaining AI adoption. And our architecture has solved that problem for our customers. trusted, secure and predictable costs are now possible for all customers regardless of size, and we began to see the results of Calix 1 and Asian Workforce Cloud in Q2. tripling Calix 1 contracts while delivering record RPOs and record software and service revenue is just a start. This is the beginning of Calix, the AI leader and now that the platform is live and running, we are excited to the opportunity for our customers to grow in the markets they serve and for our Calix team members as they leverage AI to transform how we do business and deliver operating leverage for our shareholders. Nancy, let's open the call for questions. Gary, you can open the call for questions.
Operator
operator[Operator Instructions] Our first questions come from the line Joseph Cardoso with JPMorgan.
Joseph Cardoso
analystFor my first, if I may, I just wanted to touch on your expectations for gross margins to bottom here in the third quarter. totally appreciate it's a difficult operating margin -- or operating environment. I guess what's just driving the confidence here relative to calling the floor? Is it largely related to cycling past the grandfathered backlog relative to the surcharges -- or are there other levers you're seeing relative to inventory, product redesign, et cetera, that's kind of driving your confidence here in terms of calling the floor in 3Q? And then I have a follow-up.
Cory Sindelar
executiveYes, Joseph, it is exactly as you outlined. It is the fact that we have grandfather a certain portion of the backlog and as we go through the next few quarters, that backlog as a percentage of the total will shrink. And so new orders are being -- the surcharges are being assessed that kind of our current cost structure. And we're also adjusting those now on a monthly basis as opposed to a quarterly basis. And so over time, we expect that gap to getting to gross profit neutral to improve. . And I should say that our goal for the whole surcharge boring is to get to gross profit neutral. And as we partnered with our customers this quarter to address these higher memory costs, it became clear that they value certainty and certainty of cost and more importantly, certainty of supply. And so we had to modify our program to address this. And so consequently, we did not raise prices on backlog for a second time. And meanwhile, new orders, we will we will adjust to reflect our actual costs and adjusted monthly instead of quarterly -- so as more revenue comes in from those new orders, we closer we come to being gross profit neutral. And that's why I believe in Q3 we will bottom in the client gross margin.
Joseph Cardoso
analystGot it. Makes sense, Corey. And then maybe as my follow-up, you raised the full year guide to the higher end of the range, which if I take literally at the high end implies a pretty solid sequential ramp here into the -- well into the upcoming fourth quarter. First, am I thinking about that correctly relative to how you're framing the exit rate for the year? And if so, could you help us think through the drivers given all the moving pieces? Obviously, you've guys gone into detail around the new platform momentum. I believe bead should start kind of flowing through here into the fourth quarter in terms of a tailwind -- and I assume some benefit from the surcharging pricing there. So maybe just help us think through if I'm thinking about that framing as well as maybe what are the drivers here in terms of the acceleration into the fourth quarter? -- well, I guess, third and fourth quarter, but maybe what's implied in the guidance?
Cory Sindelar
executiveYes, -- yes and yes, I think is what's the answer to that. If we take a look at what we're seeing from our customers, the demand environment remains strong and understanding that we can see all their activity through our cloud. even though we're seeing these higher surcharges and then changing their ordering paths. The underlying demand environment remains very strong. So that has not changed at all in this environment. And if you think about it, the quickest return on investment is adding a new subscriber to an existing network. And it doesn't really matter what those higher memory costs are when it comes to connecting a new subscriber to their network, they're going to move -- we're going to go ahead and buy that premise is equipment and move forward. So number 1 is the underlying demand environment is strong. . Two, you saw a return to our software growth. Exiting the second quarter, the momentum is very high. And so we reiterate the fact that we expect our software to continue to reaccelerate into the back half of the year. And you're correct that we expect to have some dead revenue pick up in the third and fourth quarters as we exit the year. No real change in terms of that demand environment. Certainly, in the beat environment is extending a little bit in a lot of areas, but as it relates to the impact to revenue for us in the second half, no changes in that environment. And so we're looking at a back half that is strong across the board.
Michael Weening
executiveLet me contextualize with a couple of customer interactions. I've been on the road quite a bit over the last quarter. talking to customers. And so the closest point I'm not adding a subscriber, it's a really salient point because we've been saying this at all times is that as organizations move to their build cycles, and, for example, they come to end of building fiber. Then their entire organization pivots away from being a really efficient construction company to how to become a really great sales and marketing organization that can win subscribers. And so the first thing I would say is that I continue to hear that theme in a lot of places. In fact, I had 1 CEO conference and the panel I was on, he basically said he can see the end of really the baby builds in fiber for his company and everything that he's thinking about is how do I add subscribers. And for Calix, that adding in subscribers means that we install a new subscriber, we provide new services, and we have an incredible strong revenue opportunity and our customer success organization and the tools we're putting place are really great at helping on the marketing side. The other side of it, though, as I said in my opening statement, which cannot be understated is that we've cracked the code on how to make AI predictable. And this means that customers all know I need AI-- and in fact, we, as Calix, as we look at the change of how we get leverage out of our operating model and how we transform our teams, we know we need AI. The biggest challenge that we had, frankly, is how do we do it in a predictable way. And this predictability cannot be understated where we believe that Calix will become the easy button because not only do we offer a predictable cost model we had 25, 30 CEOs in our office a couple of weeks ago, and we provided a very predictable road map over the coming quarters where we show workflow by workflow, here's how we're going to identify their business and where we see the payoff ROI and output. And frankly, those CEOs all left feeling incredibly enthusiastic about the opportunity to transform their teams and how AI will very clearly with the strong ROI change their business, and that's just going to snowball as other companies see this implemented within their peer group, and then they adopt quickly to you because -- it's inevitable. We you have to adopt it. It's just about what's the fastest path with the most predictability and that's what we've cracked the code on.
Operator
operatorOur next question is come from the line of Scott Searle with ROTH Capital Partners.
Scott Searle
analystCory, maybe to just dive in quickly the impact on the memory charges in the third quarter. I'm wondering if you could quantify both the sales and EPS impact. It looks like just from a cursory glance that EPS would have bracketed or maybe even been higher if you had fully implemented memory surcharges across the board in the third quarter. And then looking to the prior guidance from the Analyst Day for 27, 28. I wonder if you could give some early thoughts in terms of how are you progressing in terms of the comfort on the revenue outlook? And particularly on the OpEx front, much lower in the second quarter. It sounds like you're going to be able to continue to leverage internal AI capabilities and efficiencies to carry that forward into the future. So does the model start to change or accelerate a little bit of when we should start to see operating leverage?
Cory Sindelar
executiveGreat. So let's talk about that. We'll go ahead and talk about that first. So I think the revenue outlook is firming up. I think there are plenty of demand drivers as we look into '27, '28. Software is reaccelerating the power of the agentic workflows is resonating with customers. And so we see that we'll continue to drive our software and our software gross margins higher. We've got the tailwind of bead will happen at some point in 2027. And in the meantime, customers are continuing to add subscribers. So we're seeing no letup in terms of the demand environment. And so to reiterate our 15% growth targets for '27 '28, they're on track. In terms of the OpEx leverage, we are -- we are a leader in terms of the broadband space. We're obviously going to continue to be an AI leader in the human-centric deployment of AI and sialic -- you're starting to see some evidence of that work in the quarter. We expect more of that to come as we're committed to that as a strategy. I would say it's too early for us to accelerate that OpEx improvement, but I understand it's a keen focus inside the company to accelerate that. But I'm not changing guidance at this point, which is we will drive OpEx at a lower rate than revenue growth next year, leading to operating leverage. And we'll see what we can do to get to half or better growing at half rate revenue or better leave that as a goal, not a commitment.
Scott Searle
analystAnd Corey, just the memory impact sales and EPS in the third quarter, that would be helpful if you could provide some context. And Mike, if I could just quickly, the competitive landscape, there was a lot of talk throughout the second quarter about the StarLink impact, et cetera. I'm wondering if you could just update your thoughts in terms of, I'll call it, the terrestrial competitive landscape and then throw in the satellite impact of how that's impacting your customers and what they're doing.
Cory Sindelar
executiveYes, it's Scott. Essentially, it was a flip, right? We overperformed on EPS in the second quarter and the impact on not changing surcharges on the backlog had an impact into the quarter -- the third quarter. So we picked up a $0.05 in the second quarter. We lost a nickel in the third quarter. So for the year, we think we're EPS-neutral. -- that was part of what we thought about in terms of partnering with our customers and trying to get through this event of higher memory costs.
Unknown Executive
executiveOn the competitive landscape, excess fully like overtime competitor versus a fiber competitor. -- that changes market to market time by town. So competition exists, and it really just depends on how many people are building in that market and what their offerings are. Our position remains the same is that if you're in a market and you deploy the full car solution, you're going to be uniquely advantaged because of the fact that -- now again, this comes from a number of CEO who have proven this term over and over a guy, if you just are in market as a consumer and broadband provider, your at risk, if you are the broadband provider who takes the approach that we've built with our customers to being the dominant provider with the dominant brand in a town or an allocation you'll destroy your competition because you're selling consumer, you're winning the businesses, you're in the MDUs and that entire footprint comes together to provide enrollment capabilities through Smart Town that allows you to be the dominant brand with regards to talking to the PTI and the local school board around how do you provide WiFi roaming for all students who are underprivileged and we just want to have access to broadband to do homework. How do you provide roaming as an augmentation technology for police for inlands. They currently have their public safety radios but they could be in areas where there's worse coverage or they're using an iPhone that you've given them. And now whenever they actually hit a roaming network and whether there's WiFi coverage. Placements can actually have faster speeds and better downloads on their iPhones and the P25 radios. And all these things come together to you building a great partnership with the Mayor with the Head of Parts and Rod with all these different groups, the fire chief the police chief, and then lay become the dominant brand in your town and that brand dominance makes you local and helps you win subscribers. With regard to Sterlink, as we've always been saying forever, and the satellite providers, whether it's Starling or Amazon have a place. So if you're in a super area, it can put $500,000 to run fiber then Starlink is a great option if you're out on the boat, Starlink is a great option.
Michael Weening
executiveAnd so where it won't be an option is or where our customers know that if they lost the Starlink and they're in the town and they've got a higher connection, then they need to really look inside their business and decide what's going on because no logical customer is going to pick a sterling over fiber. The capacity differences are as phenomenal. And so fiber is going to destroy them from an experience point of view. And if the service provider does a smart thing. And the smart thing, for example, is they have to offer outdoor WiFi. And if you have the tax rate that's 40% on outdoor lipid, that customer is going to be wildly sticky because you've now put WiFi in by the pool, you got WiFi by the backyard by the garage, all those different places. And there's going to be no impetus even if StarLink uses their significant capital availability to run this at a significant loss as we expect Amazon to do that cheap off or will be beaten over by the fact that I have a great experience, I have incredible speeds I have Wi-Fi everywhere I need it. I have virus protection that protects me every day and hacking pre protection. And therefore, plus when I go to the local parks as my phone picks up and it wanders around town, why would I ever go anywhere else? So satellite has a place that 5% to 10% of the market, the matter really comes down to customer execution and they should crush.
Operator
operatorOur next questions come from the line of Christian Schwab with Craig Hallum.
Christian Schwab
analystI just want to be clear on the no surcharges on backlog. It appears to me that customer certainty on pricing and the decision not to surcharge backlog was made some time during Q2 as gross margins now are implied a little bit different than the Analyst Day on the 23rd and -- in addition, we also brought a substantial amount of stock at higher prices than where we're going to open up this morning. Is that fair? Or was that the plan all along?
Cory Sindelar
executiveNo, Christian, it was not the plan all along. Our plan all along was to be -- to do cost recovery right? That was the plan we outlined at the start of that was to get to gross profit neutral. And as we partnered with our customers, it was important for them to have certainty around price. So we've made a couple of changes. So backlog was adjusted in the second quarter. where we implemented the surcharge from the second quarter. So to say there's no surcharges on backlog is not an accurate statement. There are -- what we said is we're not going to adjust at a GaN as we move forward, right? So we gave them that certainty because customers were upset about changing price after the fact. So that was an acknowledgment of that in our partnering with them. And so the second side of that is that we've gone to adjusting surcharge pricing on a monthly basis versus a quarterly basis. so increase the frequency at which we have a chance to adjust the new orders coming in. And so that's what we've done. It had an impact to Q3 gross margins -- but ultimately, our goal has not changed, which was to maintain a gross profit neutral stance. And over time, we will narrow that gap.
Christian Schwab
analystYes. Okay. That's clear. And then on a go-forward basis, kind of reiterating the fact of 15% annual growth through '27 and '28 plus. If memory prices continue to increase and we have surcharges that 15% is an organic number, correct?
Cory Sindelar
executiveAll our growth is organic. Are you saying -- it's included surcharge.
Christian Schwab
analystRight, right. So as we get to this time next year, if memory prices continue to increase than the top line growth rate of the company should be, to some degree, greater than 15% is my question.
Cory Sindelar
executiveWe'll see about that. right? So at the end of the day, they have a -- let's break that up between access and prime. So on the premises side, I see no impact to the higher memory costs. as we talked about, as they bring on new subscribers, particularly in an existing built network, it's the greatest return on invested capital. They're going to do that regardless of whether there's incremental memory costs. On the access side, it's really driven by CapEx budgets. And as you know, we are only just a small part of the overall rising cost environment. Right. There are rising costs on fiber, labor, construction, fuel, et cetera. And so our customers, as they look at their CapEx portion of the business, we'll reevaluate how much they actually spend. So there can be actually demand destruction with the higher costs as it relates to the CapEx. But fortunately, for Calix is that the large majority of our revenue does come from the premises side. and access is a small part of the overall business. So to say that all the surcharges is additive to our revenue growth rate would probably not be an accurate statement. -- fully, that helps.
Christian Schwab
analystThat makes it very clear. No other questions. .
Operator
operatorOur next questions come from the line of George Notter with Wolf Research.
George Notter
analystI just had some questions about the Agentic Workforce Cloud progress here. I know you guys made a decision to bundle that with the other cloud offerings and not really charge customers on an a la carte basis for that. And I think the view was that you would monetize via increased subscriber penetration over time. I'm just curious like where are we now? . You've got some early feedback, I presume -- do you feel like that's still the right decision to drive for increased subscriber penetration? Do you think that model is going to work well? What's the perspective, again, a few months into the Agenticrollout?
Michael Weening
executiveYes. Great question, George. If anything, yes, we think that's 100% right. And if anything, actually, we're even more confident in that approach because of what our customers are doing is what we basically did was we took everything with her. So you would go and buy everything like you buy 1 of the 1, 2 or 3 of the clouds. -- add on 1 of our smart components, you bundle it all together and you do it all bespoke. -- which meant that customers had a lot of complexity. So on 1 side of it, our customers when we actually haven't it all in, they would say, well, on to buy it a la carte. And then when you make it out carsales -- and so by going down this approach, there's a couple of reasons why this is right. The first 1 is that you can't actually deploy effectively unless you're across the entire enterprise. So if you look at the 3 functions in the business, operations, marketing and then everything that you're doing around service or call center and field support -- every time you interact with a customer, it requires all 3 of those elements to come together in a workflow to deliver an outcome. So at the first level, we believe that this has to happen because we have to have everything -- so that wasn't really a choice. So we went forward with that and that's what we did. So that's a further part of it. The second part of it is now that we're -- we've been in market for a full quarter, our customers really know that they have to do AI and this provides them with a very clear approach to actually transform their business. Because what happens is whether or not like if I want to change my marketing team, I may or may not be ready to change it at this moment in time. But I now know that I have the dental workflows to allow me to improve marketing when I am ready, and I'm ready to couple implementing AI in marketing with a change of my team. And so this also makes us so that our customers can go at a pace that they require. And then the third part of it is our greatest growth driver is when customers add subscribers. -- making a few incremental pennies on top of a subscriber is not really the growth area. But when they -- as we said, we're $1 to $10 per subscriber, they have a new subscriber we go from 0 to great cash flow. And as you saw with -- that our margins are going back to where they were before and we're going to achieve incredible software and cloud margins, that means that that's going to be at a very, very profitable rate. And so which brings me to the last point is it's very predictable for our customers. And frankly, it's now that we've had a full quarter. It's very predictable for us. So we can deploy AI in a highly predictable way. And our intent is not to just win a little bit here and there. But as you saw by the tripling of the cloud contracts, our intent is to roll up market, and we have become -- and this will be proven with every press release that starts flowing out like crazy, which our customer success stories that we are the easy button for AI and for a path to winning more subscribers, increasing revenue per subscriber and then reducing churn, which is how they grow.
George Notter
analystGot it. And then just as a quick follow-up to that. Do you have metrics or any perspective now on customers that are actually using the genic feature? What's the feedback look like there?
Michael Weening
executiveIt's good we just started rolling out the workflows. And so we're starting to see the productivity numbers. We are now to -- it's a good question. We're now in the process with our success organization going through and doing clear measured ROI with customers. So everyone sees the value of it, but have I measured the -- we know it's there. It's just about actually getting the physical measurements done, which takes time because, hey, I know what it costs me today, what is that workflow and that process cost me 90 days from now is what we're focused on measuring. And so what you're going to see through the quarter through Q3 and as we ramp up for connections in Q4, started seeing a lot of workflows as we get that data which allows us to share with customers. That's what our press releases are focused on, is that a customer who sees a return on investment of that Agentic workflow, whether it's 10% or 7% we'll start seeing those shared out of press releases at a rapid rate through the end of the summer and into the early fall.
Operator
operatorOur next question comes from the line of Tim Savageaux with Northland Capital Markets.
Timothy Savageaux
analystAnd you mentioned a return to record gross margins on the software side, which I think prior were maybe 66%, so call it, 67 plus. I guess my question to start with, and I have a follow-up is -- where can that gross margin go? I think we have discussed the potential for that to have a 7 in front of it at some point in the future. But I'd be interested in your expectations for the trajectory of software and services margins a little bit farther out and whether there's a ceiling that we should be thinking of or how to think about that?
Cory Sindelar
executiveWe clearly see a pathway to have a 7 on the front of it. So we'll continue that mark. Ultimately, where Asentotes to is a little bit of uncertain because it depends on some of our approach related to large customers. We could actually end up in a situation where we are driving a lot more software revenue. at incredibly high gross margins and especially with private clouds, if we're doing a private instance on a large customer, the margin in that environment 100 points. . So it's hard to say kind of how fast that will accelerate or where it has and to out to but 70 is in sight, and we'll just see ultimately where it assets out to. But -- there's a lot of headroom still left to go on expanding that software and services gross margin. 70% is just a way station on to where it ultimately ends up.
Timothy Savageaux
analystGreat. And over on the appliance side, I guess, was my next question, which was -- it seems like you're looking for that to bottom and maybe tick up a bit in Q4. But again, kind of the broader question, and I don't know that you're ready to guide here, but -- is it reasonable to expect appliance gross margins to make their way back, I don't know, to the low to mid-50s by the end of 27, I guess? Or what sort of slope should we be looking at there?
Cory Sindelar
executiveWell, Tim, I would love to tell you what that looks like. But if you could tell me what memory costs are going to do, then I can probably help you triangulate on that. But if you believe the hyperscalers and their capital deployment, I think that next year will be harder than this year. but that's only if you believe those CapEx numbers. And as soon as you break on those CapEx numbers, it changes the entire pricing dynamic. So it's hard to say. So all I know is we put together a program which, over time, will get us to a gross profit neutral stance. And so kind of regardless of what those surcharges are, we're going to continue to march to that path. And we'll just see what ultimately happens next year as it relates to memory costs. And that's the best we can do at this point.
Operator
operatorOur next questions come from the line of Michael Genovese with Rosenblat Securities.
Michael Genovese
analystGreat. I guess given where we are with some Calix one's rollout, and that's just started, and you've kind of got visibility to that driving an acceleration. I guess if we just tie that into RPO, my question would be sort of -- is there a way to kind of say how many quarters in a row you think RPO could accelerate from here given the visibility that you do have to the Calix 1 acceleration and going out to more and more customers? Like should we just think about RPO going up through the end of the calendar year? Or I know RPA is usually tougher seasonally in the first half of the year. Is there reasons to think it would also be accelerating in early '27 as well?
Michael Weening
executiveYes, it's going to accelerate for sure because if you think about the year that we've had, right? So Q1 was a hamper of sales because of the fact that we were in the process of converting 1,200 customers from the previous platform to the new platform, and it was highly disruptive. -- while we had exactly 0 subscribers go down, we had some challenges with regards to some of our workflows on, frankly, on customer implementations. And so we -- and as 1 would expect that's a disruption to sales because the sales teams then are working with customers and helping them get through that. We crossed that at the end of March, which then meant Q2. While there was some cleanup that had to be done and the product team was turning off the old system, the majority of the effort got to, okay, where is the value? So we've got customers back on track, and then we started to have the conversation around, okay, what's this going to deliver? And customers are asking the same thing. What's in it for me. Why did we do this? And you saw the impact. The impact was the tripling of contracts. And I made a really important point in my comments and in the letter. And that is with regards to what were the types of customers who bought Asian workforce cloud contracts, very different. In the past, we would normally go into this cycle. Q2 would have been you have the innovators and the early adopters who are jumping all over it. Why? It is I believe in Calix, -- they know the business value that we offer. They're trying to change and improve how they run the business. They're trying to get out of it. right? While the middle majority, late majority and the laggards all sit on the sidelines and say, "I'll tell you what, when you come with ROIs like a great question, George, shown on the ROIs, but I want to see 30 of them before I actually buy because I'm the suspenders and belt decision-maker. And that was the traditional cycle, which bluntly I've been living with as a leader inside Calix since the day I started across 10 years in May. And that's been probably the biggest gating element in our business. This cycle was radically different. We actually had a customer who I have personally been trying to close for almost a decade on smart home a decade, I have called on that leader, more times than I can count to convince him to transform its business and actually deploy our virus protection and malware and all the capabilities of what we're doing in smart home and on a really good sales leader, and we could not get them over the line. that customer, who would then be called a late majority in our traditional -- if you take what we learned in Marketing 101 in University he would be in the late majority. He signed up for Calix Cloud and in fact, asked us to extend the contract beyond our normal 3-year term. Why? Because he knows that artificial intelligence is not a nonnegotiable. This is not a nice to have. This is not -- I provide my customers fiber, and I would like to differentiate my value proposition by adding virus protection and malware. This is everybody on the planet needs to deploy AI in their business or they're scored. They are going to get crushed by the competitor that does it. is that level of pressure. And every CEO is under that same pressure. I need to sit in front of my board, and it doesn't matter if my Board is sophisticated or unsophisticated. They're all -- they all know that when I come to the next board meeting, the only question I need to be asking it where very high plan and how fast is it going to drive results. We did this in a predictable way. we have become the easy button if they want to deploy AI effectively because we have a 15-year track record of demonstrating that we can be trusted bars with customers, that we do it in a secure manner. And by the way, the scariest thing about AI is how dangerous it can be from a truck and security point of view. And last, we do it predictably. And this predictability that cannot understate how important this is, it is going to be a huge inhibitor on deployment for companies who cannot provide their solutions in a predictable way. And I can tell you, inside Calix, it is stopping a bunch of our AI projects. because without the predictability with regards to what AI is going to cost and with the -- the craziness of tons -- it's very hard to -- when the team comes and says, "I'd like to do this $100,000 project to implement AI to change this element of my business. Oh, by the way, it's $100,000 to do the workflow and people transformation -- but I estimate that the token cost is going to be this, but it could be 30x as much I really don't know, which means am I losing money? Or am I actually getting a return on investment -- and I will tell you that in a specific example, we currently use copilot with all of our employees. We have a co-work proposal in front of us and that over my dead body, am I going to approve that when it's all token-based. And frankly, we looked at our pilot project and the costs or through the root -- and the ROI is nowhere to be seen other than, hey, my employee actually did a bunch of stuff better. If I can't see what the head count gains are or the productivity gains -- it's just like -- and because employees are throwing everything in the kitchen sink into the AI engine, hoping that their job will get easier. So our predictability in the form of cost -- but also, we sat down with our 1,200 customers. We know there are billions of workflows they're running, and we know what can be identified easily and what cannot, which leads to a quick ROI means that our customer velocity is going to go through the roof especially as, again, back to what George said. Great question, which is where is the ROI, well, I've got a customer success army that I talk to every single day, and they know that their #1 mandate is find out what the current KPI is, implement the workflow and get the change in KPI so that we know we can basically say, you implement this workflow, here's your ROI -- and the power that we are going to bring into the broadband market is unmatched because we have access to our customers' data in a trusted way. We have access to all of their billions and billions of workflows and we are the best place to actually turn those into AI workflows at a rapid rate. And that's why we spent 2.5 years building it out. so that we can now -- we went slow. And believe me, it was painful to actually go slow because everybody is going III and our product officer was under constant pressure from me saying, yes, that should ever it up, right? But he refused to because we knew that if we did this in a uncreable way, then the AI would start loosening and we do a all job. So everything that we're doing is trusted, secure and more importantly, predictable, not only from a business outcome point of view, which is the delivery of the ROI. So they know that they turn that works long, they're going to get this output and this improvement but also from a cost point of view, which was the architecture that Shane and his team brilliantly implemented, which allows us to use hard and open source and eliminate costs. And so all these things come together a long way of saying, at less on make money for our customers and then in turn for ourselves and our investors.
Michael Genovese
analystAwesome. Last question, just to follow up quickly. It just does seem like the third quarter guide sequentially is a little bit below historical. And so I'm just I just guess I'm asking specifically on bead, was there any kind of change from the second half of the year into the first half of next year? Or any other reason that's kind of holding back specifically the third quarter guide from being a little bit higher?
Cory Sindelar
executiveNo. I look at the third quarter guidance is in line with what we outlined in terms of expectations for the year, moving to the higher end of our guidance range that we provided last quarter. So I think on the under line, everything is tracking according to our plan. .
Operator
operatorOur last question will come from the line of Ryan Koontz with the Needham & Company.
Ryan Koontz
analystMaybe just start with some housekeeping. I know you're not reporting on customer tiers here. But could you give us any color that you saw across your different segments there and maybe the source of your 12% customer concentration in the quarter and update on any new Tier 1 engagements that may be looking at your private cloud options.
Cory Sindelar
executiveYes, we're not going to provide kind of any color on customer breakdown on mix. And the 12% customer in the quarter were liberally to disclose who that is. But the expectation is, yes, they were a 10% customer in the quarter, but they likely will not be a 10% customer for the year. So kind of understand that was a blip in the quarter and you wouldn't expect to see that happen again.
Michael Weening
executiveAnd then on customer engagement, I kind of gave a lot of color in my last answer with regards to what the engagements are like and that goes across the board. That's all sides of the customers. The contracts that we closed in the quarter were actually -- the majority of them were smaller customers, which is pretty normal lease. You see that, but we're broadly engaged in sales cycles across all customer sizes. . And the great thing now is that we're about to sell in because we've done a 2.5-year implementation and we can actually demo it and show it. So with larger customers, they have longer deal cycles. So the average -- on a large customer, a 12 to 24 months on deal cycle. So we're now deep into it. And more importantly, we're not talking about PowerPoints perhaps showing things. So great momentum.
Ryan Koontz
analystMakes sense. And then maybe on your RPOs, you talked about expecting acceleration there. We did see a divergence in 2Q between current picking up and kind of that long term, not growing as much. Can you maybe expand on that in terms of the long-term RPO expectations going forward? Do you think that will kind of normalize going forward if you get some renewals.
Cory Sindelar
executiveYes, Ryan, it's always a function of the tail on those RPOs and subject to customers coming back up for renewal. My expectation is that with the Carson contracts, we'll see an early renewal cycle. So you will probably see that total RPO growth will continue. But obviously, the current RPO is the 1 is eliminates kind of the effect of the shrinking renewal, the tail coming in. So strength in the current RPO is really what you want to focus in on. That being said, with the power of the Callison platform, I would expect customers of all sizes to renew their contracts or relate to move on to the platform. And so I think you're going to see total RPOs grow. .
Ryan Koontz
analystMakes sense. Great. And then maybe lastly on -- you talked about token costs and your use of open source and you've migrated to GCP. Can you maybe expand on that a little bit in terms of how you compare competitively with other options with your open source approach.
Michael Weening
executiveWhat other options in what regard ?
Ryan Koontz
analystWell, just if you would implement this on kind of an off-the-shelf frontier model or something like this, I mean, what type of cost savings are you seeing relative to...
Michael Weening
executiveSo let's talk about that Right. Okay. I get what you're saying. So when a company goes and use our intelligence to decide to build it in a bespoke manner. -- right? That's the first thing is that the challenge they have is that they also are now entering into software life cycles and so they need to consider that. With regards to us using a Frontier model, we're using our hard notes, the differences that we don't really see we can see the gains of it. So if you compare the gap between what is a frontier model and what is not source model, it's a very small gap, especially if you look at the workflows that we're doing. -- we're not asking this system to go and quote a new back-office system or do incredibly crazy things. We're asking it to take what is a well-defined workflow well-defined context that exists in our knowledge layer and then apply that workflow with agents to execute against clearly defined boundaries and drive great outcomes. And so our use cases, our workflows and the models that we're going after, actually, they lend themselves perfectly to this approach. So I don't need to paint you flying on a unicorn over mountain and maybe it was 3D Ascenti, right? This is not the use case. So yes.
