We assume no obligation to update these statements. Please refer to our most recent annual report on Form 10-K and other filings with the SEC for more information on the risks and uncertainties that could cause actual results to differ materially from expectations. Unless stated otherwise, today's remarks reflect non-GAAP results. Reconciliations to GAAP results are available in our press release and at investor.wdc.com. With that, I will now turn the call over to Irving.
Irving Tan
Thanks, Ambrish. Good afternoon, everyone, and thank you for joining us today. Q1 marked a strong start to fiscal 2027, reflecting solid execution across the business and results ahead of our expectations. Revenue grew 55% year over year, while gross and operating margins expanded meaningfully to 58% and 49% respectively. EPS grew 161% year over year and we generated $1.4 billion in free cash flow. These results reflect ongoing robust customer demand, operational discipline and successful execution of our product and technology roadmap. Demand remains strong across our customer base and end markets. Our visibility is extending further and with it our conviction in the durability of demand for data storage on HDDs. We are increasingly seeing storage demand grow beyond our core cloud and hyperscale customers into enterprise environments and into newer end markets such as new clouds and AI frontier labs, resulting in a larger and more diversified customer base.
Our customers are making longer term infrastructure investments and continue to extend their planning horizons into the next decade. As the value of data is increasing, they are investing with confidence to support their growing needs for data storage, with the vast majority of the data being stored on HDDs. We see this first hand in our customer conversations and in broader industry research. A recent IDC survey of more than 750 companies across several countries found that organisations are storing more data, retaining it for longer periods, and increasingly putting archive data back to earth. At the core of these trends is continued data growth, fueled by the ongoing expansion of cloud environments and the increasing storage demands from AI. While much of the conversation around AI focuses on compute, we believe the more enduring opportunity is in data. AI is fundamentally a data system. Every workload creates more data, and that data must be stored, managed, and accessed in a scalable and economical manner.
As AI adoption continues to expand across industries worldwide, data creation and storage requirements are expanding with it. Inference and agentic AI systems are generating significant volumes of logs, model outputs and system performance data that must be stored and retained. Physical AI applications such as robotics, factory automation and autonomous vehicles are further accelerating this trend with AI generated content and video workloads that are creating and retaining data at scale. Let me now turn to our industry leading technology and innovative products we are executing well against. Our technology roadmap and remain on track transitioning our customers to higher capacity drives as we ramp production across our next generation EPMR and HAMR platforms. We expect our exabyte shipments to continue to increase through fiscal 2027 and beyond. Volume production of our latest EPMR platform delivering up to 40 terabytes of capacity is off to a strong start. Customer adoption is progressing ahead of prior transitions and we expect this platform to represent close to 30% of our nearline shipments by the second quarter and 50% by the third quarter of fiscal 2027.
On our first generation HAMR product, we are on track to finish qualifications with two hyperscale customers in the first quarter of calendar year 2027 and are on schedule to begin volume shipments in the first half of calendar year 2027. We also expect to begin qualifications with two additional customers during the first half of calendar year 2027, further expanding customer validation and supporting broader adoption of our HAMR products. As AI workloads scale, customers not only need more capacity but also greater performance from their storage infrastructure. We are expanding the role of HDDs within cloud and AI infrastructure through innovations such as our high bandwidth drives and dual pivot technology. By combining the economics of HDDs with significantly higher levels of performance, we believe this technology can address a broader range of existing and emerging workloads. We are currently sampling our high bandwidth drives with multiple customers and the feedback has been positive with clear use cases and value creation identified.
In summary, WD is executing with momentum. We are deepening customer relationships, extending visibility and broadening the customer base while our product and technology roadmap delivers precisely what customers need. As data grows in volume and value across cloud, AI and emerging workloads, we have high confidence in the durability of long term storage demand. With that, let me turn it over to Chris.
Chris Senasal
Thank you, Irving. Our first quarter results demonstrate ongoing strength of our business in combination with outstanding execution on all fronts. Customer demand remains healthy and our visibility is extending further out. Our product transitions are progressing well, resulting in higher capacity products, solid year over year growth in exabyte shipments and improved pricing, all driving another quarter of strong financial performance. During the first quarter of fiscal year 2027, revenue was $4.4 billion, up 55% year over year, driven by strong exabyte growth and a favorable pricing environment. We delivered 248 exabytes in the quarter, up 22% year over year and up 8% sequentially. Nearline products continue to drive growth as we execute on our product transitions, starting with the ramp of our latest generation EPMR drives with capacities up to 40 terabytes and followed by the introduction of our HAMR technology in the first half of calendar year 2027, setting us up for stronger year over year growth in exabyte shipments.
Cloud revenue was $3.9 billion, representing 88% of total revenue and increasing 54% year over year, driven by durable demand for our high capacity nearline HDDs, including the initial ramp of our latest EPMR platform. In addition, continued pricing strength reflects the value and TCO advantages we deliver to our customers. Client represented 7% of total revenue at $320 million, up 119% year over year. Consumer represented 5% of revenue at $193 million, up 19% year over year. Gross margin expanded to 58.1%, up 1,420 basis points year over year with incremental year over year gross margin above 80%. Gross margin reflects a mix shift towards higher capacity drives, disciplined operational execution and a favorable pricing environment across our portfolio as we continue to deliver greater value to our customers. Year over year growth in average price per TB further increased to 28% versus the high teens we reported in the prior quarter.
Operating expenses were $391 million or approximately 9% of revenue, a 130 basis points sequential improvement demonstrating continuing operating leverage in the model. Operating income of $2.2 billion increased 152% year over year, driven by strong revenue growth, expanding gross margin and operating leverage. Operating margin expanded to 49.1% in the quarter, demonstrating our ability to continue to drive sustainably higher levels of profitability in the business. Interest and other expenses were $10 million and our effective tax rate was 17%. Taking into account a diluted share count of 383,000,000 shares, EPS was $4.64, an increase of 161% year over year. We generated $1.4 billion in free cash flow during the quarter and returned $1.1 billion to shareholders through share repurchases and dividends, reflecting confidence in the durability of free cash flow generation and our ability to drive long term shareholder value.
Supported by the strength of the free cash flow generation and consistent with our capital allocation framework, the Board has approved a 17% increase in the quarterly cash dividend from $0.15 per share to 17.5 cents per share, which will be paid on December 17th, 2026 to shareholders of record on December 4, 2026. Turning to the balance sheet. During the quarter, we took additional steps to simplify our capital structure by substantially reducing our remaining 2028 convertible notes. Our balance sheet remains strong and we ended the quarter with a net cash position of half a billion. Let me now turn to the outlook for the second quarter of fiscal 2027. We continue to operate in an environment of strong demand and favorable pricing in all our end markets. For the second quarter of fiscal 2027, we expect revenue to be $5.1 billion plus or minus $100 million at the midpoint. This reflects a 69% increase year over year.
Gross margin is expected to be in the range of 60 to 61% as we continue to benefit from the shift to higher capacity drives along with a strong pricing environment. We anticipate operating expenses of $400 to $410 million, a sequential increase driven by project expenses related to increased product qualification activities. Interest and other expenses are expected to be $15,000,000. The tax rate is expected to be 17%. As a result, we expect diluted earnings per share to be $5.80 plus or minus 20 cents based on a non-GAAP diluted share count of 380 million shares. As we look ahead, demand remains robust, customer engagements continue to deepen and broaden, and our visibility continues to improve. And as we execute on our technology and product transitions, we expect to accelerate exabyte supply growth throughout fiscal year 2027 and 2028. Our strong balance sheet and free cash flow generation give us the ability to make targeted investments that strengthen our technology leadership and support our customers' growing storage needs.
While we expect capital expenditures to average 4 to 6% of revenue over a five year period, we anticipate that CapEx as a percentage of revenue will be modestly above that range over the next two years as we continue to invest in heads and media, technology and factory automation supporting our industry leading aerial density and higher capacity drives without having to spend CapEx to add unit capacity. In summary, accelerating exabyte growth, technology leadership, expanding margins and disciplined capital allocation provide a solid foundation for sustainable earnings, free cash flow growth and long term shareholder value creation. With that, let's now begin the Q&A. Amrish, thank you, Chris. Operator, you can now open the line to questions, please. And to ensure that we hear from as many analysts as possible, please ask one question at a time. After we respond, we will give you an opportunity to ask one follow up question.
Operator
We will begin that question and answer session. To ask a question, you may press * and then one using a touch tone telephone. If you are using a speakerphone, we do ask you please pick up the handset before pressing the keys. To withdraw your questions, you may press * and two. And as mentioned, we do ask you please limit yourselves to a single question and a follow up. At this time, we will pause momentarily to assemble a roster. Our first question today comes from Amit Daryanani from Evercore. Please go ahead with your question.
Amit Daryanani
Yep, thanks a lot. Good afternoon everyone. I guess maybe to start Irving, there's always a lot of focus on HAMR and you know you outline sort of completing qualifications with two hyperscalers in March volume ship mid-27. Can you just talk about, you know what are the remaining milestones between those two steps from your perspective and then what determines how quickly you scale from there? Is it more driven by customer deployment schedules or your manufacturing readiness? Just any help there?
Irving Tan
Yeah, I mean, thanks for the question. First of all, I'm very pleased with the progress that we're making with HAMR. As we've highlighted in the past, feedback from our customers have been very positive, particularly around the failure rates that we've seen in our drive performance vis-a-vis what they've seen with other players within the market. As a result of that, we're very confident in terms of finishing qualifications with the two customers that we have, our first generation HAMR products in Q1. We will be starting qualification with two additional customers in the first half of calendar '27 as well. We haven't had any feedback that would give us any reason for pause in terms of translating that qualification completion to volume shipments starting first half '27. Both our customer technical support teams are working very closely with customers to complete those qualification schedules and get them into production across our global operations teams who are working closely with our own internal manufacturing assets and vendors to get the supply chain ready to support the ramp as well. And then starting in the second-half of calendar '27, we will also start qualification of our second generation HAMR drives and this will be at 5 terabytes per platter on an 11-disc platform. So overall very pleased with the progress. I think the engineering and operations teams across the company have done a great job in really helping us accelerate development of the products, the reliability of it and then we're focused very much on scaling it up and getting it into customers' hands.
Amit Daryanani
Do you have a follow up on it? I do, thanks a lot. I'm reaching maybe just to follow up on, you know, on the cost per TB. You know, I realize you folks in the past have talked about some of this input cost inflation headwind, but I think cost per TB was down like 4 or 5% in September quarter. That's the lowest we've seen in a while. Maybe you can just touch on what's happening there and what's the right way for you to think about this longer term because I do realize you're guiding for some really strong gross margins in December. So just a little bit on the cost per TB number would be helpful.
Chris Senasal
Yeah, so as Irving just indicated, we continue to execute well when our technology roadmap and product transitions basically moving to higher capacity drives based on better and higher aerial density. And so we're well on track in the long run to reduce our cost per TB approximately 10% year over year. In the near term, and I've indicated this before, this is not a surprise. We are facing some input cost increases as most of you know, we use some DRAM and some NAND inside our hard disk drives and the whole supply chain really operates in a very tight environment and so we are seeing some of those input cost increases. We are addressing all of them through value engineering initiatives that we are seeing some good traction. It takes a little bit of time to implement and qualify those solutions. And so in the near term, our cost per TB will be less than 10% down year over year. Taking us all into account, as you indicated as well, we are delivering very strong gross margins in the September quarter as well as a strong guide for the December quarter. Our incremental gross margins continue to be very strong, well above 80%. And so I think we're very well set up to continue to increase our gross margins over time.
Operator
Thank you, Amit. Our next question comes from Wamsi Mohan from Bank of America. Please go ahead with your question.
Wamsi Mohan
Yes, thank you. Irving, I was wondering if you could just address this angst around incremental capacity adds from the smallest player in the market and there's been some chatter around potential consolidation in the industry. Just would love to get your high level take on, you know what do you think could be if there is any potential impact from that at an industry level and is that impacting any of your price negotiations with hyperscale customers in the out years?
Irving Tan
Yeah, Wamsi, thanks for the question. I would say at the high level we don't see any change in terms of the long term fundamentals of both the industry or our business specifically, right. We continue to see demand continuing to be very strong, oh you know 25% plus CAGR as we've highlighted consistently in a very tight supply environment. And we remain committed to our strategy and our focus to meet that supply demand growth based on lifting aerial density. And that's delivered through technology, particularly through our head and media technology because that is the best way to deliver the best TCO to our customers and to also drive greatest profitability of our business for our business as well. And that's you know you can see that focus in terms of the both, you know, the investments we're making both into research and development and into capital investment into our head and media parts of the business. And I think the unique differentiation that we have with our own head and media development, the drive integration capability that we have gives us that confidence to be able to meet that growth trajectory, true aerial density and therefore remain committed to not investing in any incremental unit capacity. You know, there may be some other players in the market who don't have that unique ability to build their own media, build their own heads, drive that aerial density improvement and they have to compensate that by potentially maybe increasing the number of units just to maintain their share in position in the marketplace.
Wamsi Mohan
Yeah, Follow up Wamsi. Yeah, I don't really. Thanks. So on on the exabyte shipments, you grew 22% and as I'm hearing you talk about sort of the trajectory here for the rest of the year, it looks like you expect that growth to improve as you execute on these product transitions and then have HAMR in the mix. Could you just give us some sense of what it is at the high level? Like is it right to think of fiscal 27 at roughly your longer term range for the year? Is that the right way to think about it and maybe just if you think about unconstrained sort of demand, like how much higher is that relative to where your supply is and do you see that widening because of just how strong the demand is or the next, you know, couple of years? Thank you.
Irving Tan
Yeah, thanks for the question, Wamsi. We sort of see the, you know, the current quarter as being sort of the floor in terms of exabyte growth and we see that accelerating through the rest of the fiscal year. And obviously as Chris highlighted in the script of 28 and beyond that as well, that's really driven by, you know, the confidence that we have in the new platforms that we'll be introducing. Obviously, we have HAMR coming out in the first half of fiscal 27 and then as I highlight that we have second generation HAMR drive starting qualification in second-half as well. So we're very quickly at the top end going from a 32 terabyte drive to a 44 terabyte drive to a 55 terabyte drive and beyond. And that's the best way and the most economical way for both our customers and for us to be able to meet the demands that they have in terms of our products. To your question around the demand. As I said, we see that continuing to grow. We see it being very doable. There hasn't been any diminishing in demand and we don't see the gap in supply or demand that exists today perishable in the near term as well. So we continue to focus on supporting our customers the best we can with the technology that we have.
Operator
Thank you, Wamsi. Our next question comes from Eric Wuttering from Morgan Stanley. Please go ahead with your question.
Eric Wuttering
Super guys. Thank you so much for taking my questions and Congrats on a on 1/4 and a guide. Irving, can you maybe just share a bit more granular detail on your visibility comments meaning you know how far out are we talking? How many costs, how many customers are we talking and for those customers that are planning, you know that far out, just what are their exabyte needs today or in the future relative to three or six months ago? Do you see that demand kind of expanding relative to again three or six months ago? Thanks.
Irving Tan
Yeah, Eric thanks for the question. I think in terms of visibility outlook, if you take our top 7 customers as an example, we have good visibility up to 2030-2031 for across all 7 of them. And that's something that we've highlighted that we've always really much appreciated. So we can make sure we both deliver both the technology and the supply to meet that growth in demand going forward. And so we have good visibility and that in fact we see quarter after quarter the demand signal actually increasing over time. And as we move forward into the 28-29-30 time frame, we see that demand continuing to be very durable.
Eric Wuttering
Do you have a follow up? Yeah, thank you Ambrish. And then just as a follow up, you obviously just grew revenue 55% year over year. You're guiding to 69% year over year revenue growth at the midpoint in December, incredibly strong. And obviously you're referencing some exabyte growth acceleration, but that also then plot excuse me, that also implies that you're going to be accelerating pricing in the December quarter as well. So can you maybe just help us understand, you know, what is the source of that pricing acceleration is? Is that coming from the non-nearline side? Is that the nearline side? I assume it's probably both, but just any more granular color you can provide on, on why we're seeing that acceleration in up in pricing the December quarter and how sustainable that is? Thank you.
Irving Tan
Yeah, Eric, we continue to operate in a very strong favorable pricing environment. You saw our blended average selling price per TB was up 28% on a year over year basis and we saw that strength across the board in nearline and non-nearline, some of our consumer and client businesses as well. Pricing environment is strong because we do execute on our technology and product roadmap and we continue to deliver higher capacity drives to our customers that help our customers to reduce their total cost of ownership because you have better rack density, lower power consumption and a lot of benefits for our customers. As we continue to execute on that strategy and continue to deliver higher capacity drives, there is an opportunity to further enhance our price per TB over time. As you probably know, some of that business is under LTAs. As some of the LTAs are expiring and new agreements are being put in place. And in addition to that, of course, some of our exabytes are not under contract as well. And we do see a very strong price environment for those exabytes that are not under contract as well.
Operator
Thank you, Rick. Our next question comes from CJ Muse from Cantor Fitzgerald. Please go ahead with your question.
CJ Muse
Yeah, good afternoon. Thank you for taking the question. I guess Irving, you know you started the conversation talking about results ahead of expectations. And just to follow up on on the last question, you know for gross margins, you know you initially guided kind of incremental 62% and you reported 80% and now guiding 75%. So really trying to drill down as to what it is driving that, that incremental strength. Is it you know more bits that are not under contract? Is it contracts that are unwinding and repricing and I, you know, as we think beyond the near term, you know, actually think about the sustainability in 27 and beyond.
Irving Tan
Yeah, I think at a high level, CJ, first of all, we think the sustainability of gross margin expansion is absolutely there. There are three drivers of that. Obviously, you know pricing as Chris highlighted, we have a bunch of LTAs that have contractual price increases as we move into different periods as they reach sort of their anniversary, their price adjustments as we deliver higher capacity platforms to get better TCO values that were able to share in that and drive higher pricing in for those contracts that we have customers, we have LTAs with we are, we are also been able to get better spot pricing with nearline customers who aren't on LTAs given the tight supply environment. And as Chris also highlighted across the board, we're seeing better pricing environment in our client and consumer segments of the business as well. So pricing is one key element a second. We've also been up mixing our customers to higher capacity drives. So as we move them up to higher capacity, drives of CDs are more profitable for us because the ASPs per drive are much higher as well. So that's a second driver of gross margin expansion that we expect to remain over a longer term time period as well. And that obviously we'll be shipping more exabytes right to higher aerial density. And so we are able to deliver more exabytes to higher aerial density. You avoid the fixed cost of having to produce more units and that's another driver of gross margin expansion. So you put the combination of those three factors together, we feel very optimistic about ongoing gross margin expansion.
CJ Muse
Do you want to follow up CJ, I do embrace. Sure, thank you. You talked about a broadening breath of customers and including enterprise and NCPS. I'm curious how how is that perhaps changing the duration of LTA pricing and deposits perhaps just would would love to hear you know how how your customer base is, is evolving and how that might impact kind of your contracts. Thank you.
Irving Tan
Yeah. So we, we appreciate, I would say a diversification of our customer base, right And something that we've communicated in the past where the sort of three tier architecture, the critical role that HDDs play both in terms of the scalability, reliability and the economic value that provides to customers is truly playing out right. And we definitely see that demanding happening from the Frontier AI labs, from the new cloud players and also hybrid cloud solution OEM providers as well. So we're factoring in the our demand signal as well as we look forward and has that's translating into the expanding demand signal that we've highlighted in my response to the earlier questions. And again, where we're delivering, we're building technology, we're making investments into head and media to be able to provide the aerial density and the capacity to support all our customers in this more diversified customer environment.
Operator
Our next question comes from Asaya Merchant from Citigroup. Please go ahead with your question.
Asaya Merchant
Great, thanks a lot. Irving, I think you talked about some of the high bandwidth drives as well an opportunity there to grow. Maybe if you could just double click on, you know, how, how big is that opportunity today? How many of these are you shipping, if you can elaborate on that and how big do you think that opportunity could be for you? Thank you.
Irving Tan
Yeah, thanks for the question as yeah, I look, I think the the opportunity is still somewhat nascent today. Our primary focus is obviously to get capacity into the hands of the customers. But as we move into latter part of calendar 27-28 and beyond, this becomes what we feel a big differentiator for us because things like high bandwidth drives provide customers with an opportunity to use HDD for different workloads that they may have to use alternative storage media for, which may be much more costly. For example, KV cache workloads in AI inferencing and in video streaming as well. So we've been actually providing samples to many of our customers in terms of this product so that they can test out different use cases. And I highlighted that's been very positively received. And so we're working through sort of the commercial structure of how we would price those high bandwidth capabilities to customers. But from a technical capability standpoint, very positive we're working through the sort of commercial construct of how we would price that going forward.
Asaya Merchant
Did you have a follow up as here? Yeah, go ahead. Yeah, sure. If I can, if I can just ask about the physical AI as well. You know, I think you talked about that as well in your script. You know, any early indications again of, you know, how big is that opportunity today? Are you shipping towards that probably still, you know, in the early innings now, but how do you think about it through calendar 27 and into calendar 28? Thank you.
Irving Tan
Yeah, I think we're definitely seeing very promising signs from the physical AI segment of the markets. For example, some of our customers in Asia who are in the autonomous vehicle space are definitely looking for increased demands supply from us to be able to support their physical AI initiatives. A good data point of that is, you know, NVIDIA themselves have just recently highlighted the opportunity in terms of their revenue from physical AI being in the $10 billion range, right? So if you see that happening in compute, there's obviously the demand for storage to support that compute as well. So we see it very positively. Obviously, autonomous vehicles will be 1. Robotics is also becoming a key area for us. A lot of it's actually happening out in Asia, but I anticipate that will happen throughout the rest of the world over the next two to three years as well.
Operator
Thank you. Our next question comes from Ben Ratzis from Melius Research. Please go ahead with your question.
Ben Ratzis
Yeah, Hey guys. Thank you. I appreciate it. I wanted to go back to one of the earlier questions on, on want the competitive aspect of adding capacity. You know, I think there's there's just some basics that would be helpful. You know, how, how can somebody go from 10 to 30% capacity share? Is there enough, you know, materials to do media and heads to be able to do something like that? You know, maybe maybe you can address the question from from that and what would be the, you know, it is your view that somebody could do that and what would be the bottlenecks in doing so?
Irving Tan
Yeah, Ben, thanks for the question. I, I can't comment about somebody else doing it. I can share what we are doing to enable it. So first and foremost it all starts with technology. R&D teams do a great job in terms of designing, you know, head designs, media recipes to really enable high high density products. Obviously we combine that with our firmware capabilities and drive server mechanics capability. So it's not only about the individual components, but when you integrate all of it together, do you get the optimum aerial density per drive. So that's really at the engineering level and that's one of the big differentiators that we feel versus maybe one other player in the market who is dependent on 3rd party supplies. So they're not vertically integrated. Secondly, you know as you you've touched on a key element of it is not so much the unit capacity that you have, it's the availability to produce the at scale, the needed media and hits to support the higher air density in the drives as well. And again, that's something we have been and will continue to make investments in, in WD both in terms of our R&D capability, but also into our manufacturing assets specifically to enable greater air density to our head and media assets to drive that. So I think that's what we're doing and and we see the the results of that. Other organizations that don't have that degree of vertical integration, I would say we'll have a harder time being able to reach the same levels of growth that we are seeing.
Ben Ratzis
You follow them? Yeah, thanks a lot, Amber. You know, there's there's obviously a lot of fear out there as you guys see and and well know going into this call. I was just wondering if you give more color around how big, you know, clouds are for you now and in your forecast and and if there was a hiccup in demand there just due to timing of capital, you know, how we would see it and how big a concern would that be for you? Thanks.
Irving Tan
Yeah, I think first of all, you know, we need to take a step back there. There really 4 drivers of growth within the storage space, right? One is the the ongoing secular growth of the cloud and the cloud itself that's been around for those to do tag gates is still growing at a very healthy pace, in fact accelerating really driven by a lot more storage being driven by video content. So a lot more demands because a lot of content being stored is video. And obviously a lot of the cloud based services are becoming AI enabled. So that's driving greater storage requirements. So that's one key driver of growth that will continue over the foreseeable future. The second driver of growth has been model training and development. And we see that continuing to grow as as new models get created. As reinforcement learning is happening, more data needs to be stored to support reinforcement learning of existing models. As well and that's where the Neo clouds do do play a part in, but we don't see that being in any way major hiccup if there is a bit of a slow down in the Neo Cloud segment. The third is around inferencing and agentic AI and that's where we see a lot of opportunity going forward and we starting to see tremendous amount of growth coming from that area as customers need to store logs, checkpoints, more outputs of that inferencing and sort of the agentic system decision points to support reinforcement learning as well. And then finally physical AI that we've just touched on as well. So if you if you add those four things together, I think the demand remains very doable, durable even if there may be a slight softers in one of the four segments, the demand will be easily picked up by any one of the other tree. So all things added together, we see very positive outlook in terms of the demand remaining strong and remaining durable. In terms of how we look at the Neo clouds, I mean, obviously we are very diligent in looking at the strategic Neo clouds that we want to engage with. Those that we think have a very strong balance sheet have underpinned by a very good end customer base as well. And so we prioritize that over other players within the market.

Thank you. Our next question comes from Tom O'Malley from Barclays. Please go ahead with your question.
Tom O'Malley
Hey, guys. Thanks for taking my question. Appreciate it. So if I look at kind of the the CAGR of total HEDXY shipments over the last couple of quarters, it's range from low 20s kind of up to the mid 30s. And I plugged that in for your guide. It looks like your year over year pricing that's implied for the December quarter is, is above that 30% year over year mark. So you guys have historically kind of said high teens is the sustainable growth rate. You are now well above that for the past couple of quarters. Do you do you think you could give us an update about what the right way to look at that is in terms of sustainability of that pricing increases on a go forward basis?
Chris Senasal
Yeah, Tom, I think the the 10% or whatever number you were referencing that we are we're operating while above that, right. Just in the one quarter ago, we were already at 18% ASP increase on ASP per TB basis. And and so last quarter we did 28. And as I indicated before, given the strong demand environment that we operate in, given the fact that we continue to move to higher capacity drives and continue to add more value to our customers, there is definitely further room for ESP per TB increases going forward over the next, call it 3, four quarters. I would assume eventually that is going to slow down a little bit, but for the next 3, four quarters, there's definitely further room to expand our ASP per TB year over year growth.
Tom O'Malley
You have a follow up, Tom, I do thank you. Just following up on the commentary, just the CapEx on average 4 to 6% of Revs over a five year. But modestly ahead of that in the next two years. I think like the knee jerk reaction to that is making sure that that is just investing in heads and this is not something about expanding capacity or feeling like you need to take advantage of a market as it's nearing a potential peak. Not saying that, just just outlining what you could hear. So maybe could you spend a little bit of time talking to us about, you know, why the investment is needed in heads? Is this around diversification efforts because of what we've heard in the media lately or just a desire to get your internal efforts to a better spot? Would love just to hear your kind of thoughts on that. Thank you.
Irving Tan
Yeah, yeah. And, and Tom, just to be clear, in the prepared remarks, we explicitly said that the CapEx is going to head and media and factory automation and not to expanding our unit capacity. Yeah. So I, I, I think Chris summarize it really well and, and obviously as we, we look to transition to HAMR, obviously there are longer cycle times in terms of the steps that are involved in terms of the, the hits that we need hit wafers that we need to produce and also the media products that we need to produce. So we're making the appropriate investments to support both the technology capabilities and at the same time to recognize that there are slightly longer cycle times because slightly more steps that are involved to produce the head and media components that's needed for HAMR.
Operator
Thank you, Tom. Our next question comes from Timothy Arcuri from UBS. Please go ahead with your question.
Timothy Arcuri
Thanks a lot. You guys talked about an acceleration in exabyte growth. You've been under shipping your peer by about 10 points there. They're you're sort of mid 20s and they're sort of mid 30s. So, so Chris, when you mention that, like what is the target? Should we think that maybe over a multitude of quarters you could get to like the mid 30s is the goal to sort of close that gap?
Chris Senasal
So yeah, we, we did 22% last quarter and we we've we've talked about that. We are in between 2 product transitions. We, we, the last couple quarters, we executed really well on our up to 32 terabyte EPMR transition. We are now started to execute on our up to 44 terabyte EPMR transition. And then we have our HAMR transitions first and second generation coming up and that is going to drive a meaningful increase in our aerial density and and a meaningful increase to higher capacity drives and that will definitely accelerate our exabyte year over year supply growth over the next 678 quarters.
Timothy Arcuri
So follow up, Tim, do you think I do? I do, yeah. So just to just to kind of double click on that. So Chris, should we think of you in six quarters shipping like 35% exobite growth? Is that the message?
Chris Senasal
So we, we only guide in 1/4 at a time, but you, you you're thinking about it in the in the right direction.
Timothy Arcuri
Yeah. OK. Thanks.
Operator
Thank you, Tim. Our next question comes from Krish Sankar from TD Cowan. Please go ahead with your question.
Krish Sankar
Yeah, thanks for taking my question. I told them to and just thanks for the color on the pricing. I'm just curious as your most set of HAMR customers ramp in the first half, would there be any impact on the ASP growth, mainly because you're helping your early customers ramp HAMR or should not have any impact?
Chris Senasal
No, we're not discounting our HAMR products in any way versus our EPMR products. So we price them on a dollar per TB basis and we have LTAs that we that I mentioned that have you know appropriate price reviews and periodically. And so whether we ship a HAMR bit or EPR bid, the price is the price.
Krish Sankar
Got it, got it. And then as a quick follow up, you know, I totally understand the argument about adding head capacity, but not units. I'm just try to play the devil's advocate by adding head capacity you are, you know increasing the capacity per unit. So I'm just wondering isn't that lead to the fact that you are actually adding capacity even though if it's head not unit leading to more capacity increase versus you know the menu share between a unit or the head?
Irving Tan
Yeah, I think there are two factors there. First of all, we say we are investing into hit capacity and part of it is as I mentioned, you know, for example, a HAMR hit does require more cycles to produce. So there's a bit of throughput loss. So we need to offset. So we do need to put in more capacity. So that does not translate into more hits and therefore more units. And we, we have also indicated that our innovation day back in February of this year, we have a road map to deliver drives with up to 14 platters as well. And therefore you will will need more hits within the existing number of drives that we have as well. So we are we're making the investments to support that road map going forward as well. And Krish, last quarter we shared with you the planner count growth on very minimal unit growth, right. So that's one of the reasons we have to invest on the head side.
Krish Sankar
Thank you. And that applies to me there as well. Same, same thing.
Operator
The next call please. Our next question comes from Jim Schneider from Goldman Sachs. Please go ahead with your question.
Jim Schneider
Good afternoon. Thanks for taking my question. I was wondering if you can maybe just clarify with respect to your head strategy currently, whether you use external vendors for any of your products or for surge capacity? And to what extent the head investments beyond just the the HAMR items you've mentioned before are meant to sort of eliminate the need for any potential vendors in the future and sort of take that external reliance off the table completely? Thank you.
Irving Tan
Yeah, thanks for the question. So we, we do use some external HIT capacity that we always have done. We do that for meter as well. That is part of our sort of innovation approach where we build and buy. So we're able to benchmark our performance of our components with our the third party suppliers. As well as a great way for us to continue to drive innovation both internally and with our partners as well. Our focus on our investment is to continue to ensure that we have the latest technology internally to support our products going forward. What we do buy from third parties are typically used in our lower capacity drives. So all the high cap leading edge platforms that we introduce are all on our own internal hips.
Jim Schneider
Do a follow up, Jim. Thank you. Yeah, just as a follow up in, in a hypothetical situation where one of your competitors were to, you know, meaningfully expand unit capacity, what what hypothetic would be for your response in that case?
Irving Tan
Well, again, you know you can, it boils down to not just unit capacity, but what at what capacity point is unit shipping at as well. So again, our focus is on delivering that capacity that customers need to higher capacity drives to aerial density. So you know our response is going to be the same as we've communicated over the last year to continue to focus on the aerial density to translate that into the highest capacity drives that we can bring into the market. That's the best TCO for customers and drives the best economics for us as well.
Operator
Thank you. Next caller, please. Our next question comes from Carl Ackerman from BNP Parabola. Please go ahead with your question.
Carl Ackerman
Yeah, thanks for squeezing me in Urban. And Chris, you indicated that HAMMER will ramp over the next couple quarters, but you expect non HAMMER nearline Dr. capacity to also expand while Hammer ramps as well.
Irving Tan
So we expect obviously that we are looking to ram HAMR in the first half of calendar 27. In parallel, we will also continue to ramp and supply our latest EPMR platform. As we highlighted, it's making, it's making a very successful transition, in fact the fastest transition of any EPMR platform that we've seen. You know in this quarter, Q2, we expect 30% of all the nearline bits to be on that 40 up to 40 terabyte platform. By Q3 of calendar of fiscal 27, we expect 50% of all the nearline bits that we ship will be on that 40 terabyte platform as well. And then obviously we'll continue to scale. So I think we have two very strong horses in the mix to deliver high cap drives to support the demand that our customers need.
Operator
Thank you, Karl. We have time for one more caller. Operator, please. Our next question comes from Mark Newman from Bernstein. Please go ahead with your question.
Mark Newman
Hi, thanks for squeezing me in. Congrats the numbers today. I wonder if I could just ask a bit more on the pricing. Pricing continues to be extremely strong and this last quarter seems to be further accelerating. You talked about you have demand visibility all the way to 2030-2031. I wonder if you could update us on how far out you have for a price visibility such as in your purchase orders already signed or long term agreements how, how far out should we expect this price to remain continuing at this cadence or potentially could we expect it to further accelerate from here? Any comments on price visibility from here would be great. Thanks.
Irving Tan
Yeah. So the most important thing with LTAs and our customer engagements is to create that long term visibility and making sure we are aligned from a technology and product roadmap. We're aligned on those product transitions that are being planned ahead for the next couple quarters and years. And and making sure that we put in place the necessary exabyte capacity to support the demand. That's the most important thing that we're trying to achieve here in, in terms of pricing in, in those LTAs we do have some pricing components, keep in mind that there is base volume, there is upside volume. So there is definitely some flexibility. And keep in mind of course that not all our exabytes are covered by the LTAs the further you go out, the less of it is covered under LTAs and for sure under pricing component of the LTAs. So we think in the current environment that's the best way to approach it. And again, as we for us, it's all about. Execution order, technology, product roadmap, get to the higher capacity drives deliver more value to our customers and that's a very favorable setup for pricing and further increases in our ASP per TB.
Mark Newman
Thank you, Mark. But can I ask one quick follow up on the exabyte growth, 22% year on year is sure. I believe you guided long term exabyte growth for nearline at 25%. I just wanted to clarify that if that is still intact, which also your competitor had also outlined, is that 25% of good guidance long term for nearline exabyte growth?
Irving Tan
Yeah, we actually said greater than 25%, right. And and again, we've indicated that currently it's slightly below the 25% because we are in between those two product transitions. But as the product transitions are getting more traction, we will exceed that 25%.
Mark Newman
Great. Thank you very much.
Operator
And at this time we will conclude today's question and answer session. I would like to turn the floor back over to Irving Tan for closing remarks.
Irving Tan
Thank you, operator. I would like to leave all of you for few thoughts. The first phase of AI investment focus on building the infrastructure to train models. Even as that continues, the next phases are about deploying AI to work at scale, from inference to agents to physical AI. As that happens, data will continue to compound, driving customers to plan further ahead, adopt higher capacity products, and align their infrastructure Rd. maps more closely with our technology roadmap. For WD, this creates an opportunity that extends well beyond initial AI infrastructure build out. As AI scales, data creation and associated storage requirements will accelerate and compound. As always, my thanks to our customers, partners at the entire WD team, for all of you, for your interest and support of WD Thank you.
Operator
The conference has now concluded. We do thank you for attending today's presentation. You may now disconnect your lines.
