Antonio Neri - Chief Executive Officer

Thanks, Andy. Good afternoon, everyone. Thank you for joining us today. While great progress is made in the fight against COVID, it's also clear that it's still a global challenge. I want to take a moment to acknowledge the suffering occurring in India and elsewhere as communities confront devastating COVID surges. We will continue to do everything we can to support our team members, customers and communities through this very challenging time.

Hewlett Packard Enterprise had a strong second quarter. I'm very pleased with our results and they are marked by revenue growth, strong profitability and free cash flow. The overall demand environment is improving and we are seeing traction across our portfolio. We saw solid sequential improvement in total HPE orders growth, that was up mid-single digits, with double-digit growth in HPE GreenLake and HPC business segments. We expect to continue to see improvement in customer IT spending throughout 2021.

Our disciplined execution on our strategic priorities outlined at the Security Analyst Meeting last fall is positively impacting both top and bottom-line performance. We are strengthening our core businesses, doubling down in key areas of growth and accelerating our as-a-service pivot, while advancing our cloud-first innovation agenda to become the edge-to-cloud Platform-as-a-Service choice for our customers and partners. We have also executed well throughout the industry-wide tightening and cost inflation influence with minimal impact to our first half. We have taken proactive inventory buffering measures to position us well for the second half.

We will continue to take additional inventory actions as appropriate, in alignment to the market demand by leveraging great engineering capabilities and our long-term agreements with our suppliers. Our continued strong performance give us the confidence to raise our fiscal year '21 EPS and free cash flow outlook for the third time since our Security Analyst Meeting. We will provide more details about this new guidance later in the call.

First, let me review some key Q2 highlights. Revenue of $6.7 billion was up 9% year-over-year with better than normal sequential seasonality. I'm particularly pleased with the double-digit revenue growth in both our HPC and Intelligent Edge businesses that together now represents 22% of our HPE total revenue.

Our as-a-service annual recurring revenue growth was an impressive 30% year-over-year, which underscores our momentum in enabling consumption-based IT. This is an important long-term growth driver for our company. We made significant improvements in both gross and operating margins. Our non-GAAP gross margin of 34.3% is at record level and up 210 basis points year-over-year. Our non-GAAP operating profit of 10.2% is up 300 basis points year-over-year. And our non-GAAP EPS of $0.46 is up 70% year-over-year and above the high end of our outlook range. These results contributed to Q2 free cash flow of $368 million, which is up $770 million year-over-year, bringing our first half fiscal year '21 free cash flow to a record $931million.

Tarek will discuss the financial results and outlook in greater detail. Before he does that, I want to provide additional comments on our business segment performance and highlight some of the innovative solutions and experiences we introduced during the quarter. HP has been driving transformation in our businesses to deliver a modern secure cloud experience everywhere to help our customers with their digital transformations. Our Intelligent Edge business accelerated this momentum with an outstanding quarter across all metrics. Revenue of $799 million grew 17% year-over-year and operating profit expanded 320 basis points year-over-year. This is the third consecutive quarter of year-over-year revenue growth and sixth consecutive quarter of operating profit expansion.

Edge-as-a-service offerings were up triple digits year-over-year and now a meaningful contributor to HPE's overall ARR. Extended to the edge has never been more critical for enterprises. At Aruba Atmosphere, our signature event for Aruba customers and partners, we announced an expansive set of cross-portfolio edge-to-cloud security integrations for our Aruba Edge Services platform, or ESP, including SD WAN technology from our recent Silver Peak acquisition.

Today, our Aruba Edge Services platform already supports well over 100,000 customers, with 150 new customers added every day, connecting over 1 million active devices. Aruba building an identity network security is unique in the market and provides the ideal foundation for building a zero trust and secure access service edge.

Our comprehensive portfolio and AI-powered cloud-driven platforms like Aruba ESP and Aruba Central will continue to accelerate WAN and security deployments, advanced cloud and IoT adoption and fast track digital transformation. Customers like Walgreens Boots Alliance and MercadoLibre chose Aruba in Q2 for these reasons. I am tremendously pleased with Aruba's impressive performance and it is against this successful backdrop that I want to share that Aruba Founder, Keerti Melkote, has made the decision to retire from HPE.

We acquired Aruba in 2015 when we saw the edge as the next frontier. Aruba and Keerti has been instrumental in accelerating this business to the $3 billion business it is today. I'm incredibly grateful for his leadership and I have personally benefited from his counsel, knowledge and friendship. Keerti will remain as an advisor to me for the remainder of 2021.

I am pleased to announce that effective today, Phil Mottram will take over the leadership of our Aruba Intelligent Edge business. Phil is a results-driven leader with extensive experience implementing growth strategies and leading transformation initiatives. He joined HPE in 2019 and most recently assumed the role as the General Manager of our Communications Technology Group, leading a team of more than 5,000 team members who drive $500 million in CTG specific revenue and $3.5 billion in total revenue for HPE. I'm excited to welcome Phil to into this new role and believe he is a perfect fit to ensure we maintain our leadership position and some momentum in the market.

In our high performance computing and mission-critical solutions business, revenue of $685 million was up 11% year-over-year. We are the undisputed market leader with an industry-leading portfolio in AI, in people and in solutions for the new age of insight. We continue to execute on over $2 billion in awarded contract and we are pursuing a robust pipeline of another $5 billion in market opportunity over the next three years.

In Q2, we announced several new HPC systems deals and collaborations. This includes building new supercomputer to advance scientific research for the Swiss National Supercomputing Center, the United States Department of Energy, Los Alamos National Laboratory and the National Supercomputing Center in Singapore. As we have noted on previous calls, this is an inherently lumpy business due to the lead times between order and revenue recognition, but we remain on track to deliver our target of 8% to 12% annual growth in this business this year.

Our Compute and Storage businesses performed very well in the quarter. Our strategy to grow in profitable segments of the market and pivot to more as-a-service solutions is paying off. In Compute, revenue of $3 billion was up 10% year-over-year with our strong operational performance, expanding operating margins by 550 basis points.

We expanded our portfolio with the latest AMD EPYC and Intel Xeon Scalable Processors, which include the launch in three new HPE ProLiant solutions, targeting 5G deployments in telco, virtual desktop infrastructure and storage optimized solutions for database overloads in enterprise. The storage revenue of $1.1 billion was up 3% year-over-year with a strong operating profit of 16.8%, up 110 basis points year-over-year. We continue to see strength in key software defined solutions, which drive out our ability to attach rich services to our product offerings. HPE Primera and Nimble dHCI both grew triple digits. Our HPE's all flash Array portfolio grew 20%.

On May 4, we introduced a new portfolio, cloud native data infrastructure called HPE Alletra. This portfolio delivers workload-optimized systems and provides customers with architectural flexibility to run any application without compromise from edge-to-cloud with a cloud operational experience. These innovations are propelling our storage business into a cloud-native software-defined data services business.

Our pivot to as-a-service continued its strong momentum. Our annualized revenue run rate of $678 million was up 30% year-over-year. We saw strong total as-a-service order growth of 41%. Over 900 go-to-market partners are now actively selling HPE GreenLake as a part of their own marketplace. And we average a 95% renewal rate with billings from those customers at 124% usage of the regional contract commitments. We have an unmatched portfolio of hybrid cloud services that spans all aspects of networking, compute, storage, VMs, containers, MLOps, HPC and more.

On the innovation front, we announced a transformative new data storage services platform that brings our cloud operational model to whatever data lives [Phonetic] by unifying data operations. The platform will be available through HPE GreenLake Central and includes a new data services cloud console and a suite of software subscription services that simplifies and automates global infrastructure of scale. Our industry-leading HPE GreenLake Cloud services experience [Phonetic] enable us to get more than 90 new customers during the quarter. Clearstream is a great recent customer example. In a three years multi-million dollar deal, Clearstream selected HPE GreenLake cloud services with HPE Ezmeral software and HPE Pointnext services to power a transformative new healthcare initiative based on artificial intelligence as-a-service.

We will continue to invest aggressively in HPE GreenLake cloud services to provide a true cloud experience and operating model, whether at the edge, on-premises, across multiple clouds. HPE businesses that provide services and capability of our customers digital transformation also performed well in Q2. HPE Pointnext operational services had another solid quarter with revenue growing year-over-year as reported. We expect to see growth for the full fiscal year, driven by our growing services intensity and other service momentum.

HPE Financial Services continues to play an important role helping our customers as they rebuild and rethink their IT transformation requirements. Cash collections continue to improve and HPE FS delivered a return on equity of 18.3%, well above pre-funding levels. This business continued to perform very well.

Over the past year, our global communities have faced a catastrophic health crisis and significant business disruption. At HPE, we accelerated our strategy to be the edge-to-cloud platform as-a-service company, to support our customers' rapidly changing needs. Throughout this time, our 60,000 team members demonstrated amazing agility and perseverance. And I'm tremendously proud of our team members' response during this unprecedented time and want to thank them for their commitment and passion that has made HPE stronger and better positioned in a world that has forever changed.

As businesses emerge from the pandemic and move beyond the age of COVID, digital transformation is at the forefront of their strategic initiatives. At our Discover event on June 22, you will hear more about how HPE is at the center of this turbo-charged digital economy. Our edge-to-cloud architecture, software and solutions, all delivered as-a-service, will continue to help our customers transform their businesses, optimize their applications and data across our increasingly distributed awards and be future-ready today. I'm excited about our momentum and I believe HPE represents a strong investment opportunity for our shareholders.

With that, let me turn it over to Tarek to review the quarter's results.

Tarek Robbiati - Chief Financial Officer

Thank you very much, Antonio. I'll start with the summary of our financial results for the second quarter of fiscal year '21. As usual, I'm referencing the slides from our earnings presentation to guide you through our performance in the quarter. Antonio discussed the key highlights for this quarter on Slide 1.

And now, let me discuss our financial performance starting with Slide 2. I am very pleased to report that our Q2 results reflect continued momentum in revenue, strong gross and operating margin expansion and robust cash flow generation. We delivered Q2 revenues of $6.7 billion, up 9% from the prior year period, the level better than our normal sequential seasonality.

I am particularly proud of the fact that our non-GAAP gross margin is at a record level of 34.3%, up 210 basis points from the prior year period and up 60 basis points sequentially. This was driven by strong pricing discipline, cost takeout and an ongoing favorable mix shift towards higher margin software-rich offerings.

Our non-GAAP operating expenses increased in the quarter, as we previously indicated due to the planned hiring increases along with R&D and go-to-market investments, this offset by our continued progress delivering on the savings from our cost optimization plan, which is on track. Even with our investments, our non-GAAP operating margin was 10.2%. That is up 300 basis points from the prior year, which translates to a 59% year-over-year increase in operating profit.

Within other income and expense, we benefited from one-time gains related to increased valuations in our Cohesity and IonQ investments within our Pathfinder venture portfolio. As a result, we now expect other income and expense for the full year in fiscal year '21, to be an expense of approximately $50 million.

With strong execution across the business, we ended the quarter with non-GAAP EPS of $0.46, up 70% from the prior year and meaningfully above the higher end of our outlook range from Q2. Q2 cash flow from operations was $822 million and free cash flow was $368 million, up $770 million from the prior year, driven by better profitability and strong operational discipline as well as working capital benefits. This puts us at a record level of free cash flow for the first half at $931 million. Finally, we paid $156 million of dividends in the quarter and are declaring a Q3 dividend today of $0.12 per share payable in July.

Now let's turn to our segment highlights on Slide 3. In Intelligent Edge, we accelerated our momentum with rich software capabilities to meet robust customer demand, delivering 17% year-over-year revenue growth across the portfolio. Switching was up 17% year-over-year and wireless LAN was up 16%. Additionally, the edge as-a-service offerings were up triple digits year-over-year and now represent a meaningful contribution to HPE's overall ARR. We also continue to see strong operating margins at 15.5% in Q2, up 320 basis points year-over-year, which is the sixth consecutive quarter of year-over-year operating margin expansion.

Silver Peak continues to perform well, leveraging the high growth as you had market opportunity and contributed about 5 points to the Intelligent Edge top line growth. In HPC MCS revenue grew 11% year-over-year as we continue to achieve more customer acceptance milestones and deliver on our more than $2 billion of awarded contracts. We remain on track to deliver on our full year and three-year revenue growth CAGR target of 8% to 12%.

In Compute, revenue grew 10% year-over-year and was down just 1% sequentially, reflecting much stronger than normal sequential seasonality. Operating margins were up meaningfully year-over-year, due to disciplined pricing and the rightsizing of the cost structure in this segment. We ended the quarter with an operating profit margin of 11.3%, up 550 basis points from the prior year period and towards the upper range of our long-term margin guidance for this segment provided at SAM.

Within Storage, revenue grew 3% year-over-year, driven by strong growth in software defined offerings. Nimble grew 17% with ongoing strong dHCI momentum growing triple digits. All-Flash Arrays grew 20% year-over-year, led by Primera that was up triple-digits and is expected to surpass 3PAR sales next quarter. The mix shift towards our more software-rich platforms and operational execution helped drive storage operating profit margin to 16.8%, up 110 basis points year-over-year.

With respect to Pointnext operational services, including Nimble services, revenue grew for the second consecutive quarter year-over-year as reported with further growth expected for the full year of fiscal year '21. This has been driven by the increased focus of our BU segments on selling product and service bundles, improved service intensity and our growing as-a-service business, which I remind you, involves service attach rates of 100%. This is very, very important to note, because all of our OS revenue is recurring with three-year average contract length and OS is the highest operating margin contributor to our segments.

Within HPE Financial Services, revenue was down 3% year-over-year as the pandemic did not materially impact this business until later in 2020. As expected, we are seeing continued sequential improvements in our bad debt loss ratios ending this quarter at just 75 basis points, which continues to be best-in-class within the industry. We have also seen improved cash collections well above pre-COVID levels. Our operating margin in this segment was 10.8%, up 160 basis points from the prior year and our return on equity at 18.3% is well above pre-pandemic levels and the 15%-plus target that we set at SAM.

Slide 4 highlights key metrics of our growing as-a-service business. Similar to the past couple of quarters, we are making great strides in our as-a-service offering with over 90 new enterprise GreenLake customers added, that is in Q2, bringing the total to well over 1,000. I am pleased to report that our Q2 '21 ARR was $678 million, which was up 30% year-over-year as reported. Total as-a-service orders were up 41% year-over-year, driven by strong performance in North America and Central Europe. Our edge as-a-service offerings also continued to grow revenues strong triple digits year-over-year. Based on strong customer demand and recent wins, I am very happy with how this business is executing and progressing towards achieving our ARR growth targets of 30% to 40% CAGR from FY '20 to FY '23.

Slide 5 highlights our revenue and EPS performance to-date where you can clearly see the strong rebound in momentum from our Q2 '20 trough. For the past two quarters, revenue has exceeded our normal sequential seasonality, reflecting the improving demand environment. And with the operationally execution of our cost optimization and resource allocation program, we have increased non-GAAP EPS in Q2 by 70% year-over-year.

Turning to Slide 6. We delivered a record non-GAAP gross margin rate in Q2 of 34.3% of revenues, which was up 60 basis points sequentially and up 210 basis points from the prior year. This was driven by strong pricing discipline, operational services margin expansion from cost takeout and automation and a positive mix shift towards high margin software-rich businesses like the Intelligent Edge and next-generation storage offering. We have also benefited from the new segmentation we implemented beginning of fiscal year '20 that has given us much better visibility into each business unit and enabled better operational discipline.

Moving to Slide 7. You can also see we have expanded non-GAAP operating profit margin substantially from pandemic lows of - to 10.2%, which is up 300 basis points from the prior year period. We have done this by driving further productivity benefits and delivering the expected savings from our cost optimization plan, while simultaneously increasing our investment levels in R&D and field selling costs, which are critical to fuel our long-term innovation engine and revenue growth targets. Q2 operating expenses also included planned increased hiring and spending on select investments to drive further growth.

Turning to Slide 8. We generated a record first half levels of cash flow with $1.8 billion of cash flow from operations and $931 million of free cash flow, which is up $1.5 billion year-over-year. This was primarily driven by the increased profitability, strong operational discipline and some in year timing related benefit. I would like to underscore that this year, our free cash flow profile seasonality will be different as a result of our back-end loaded restructuring cost and investment in inventory for our supply chain to cater for rising demand and chip shortages as the economic recovery accelerates.

Now moving on to Slide 9, let me remind everyone about the strength of our diversified balance sheet. As of April 30 quarter end, we have improved the operating company to a net cash neutral position with our strong free cash flow. Furthermore, we have made good progress securitizing some financial services related debt through the ABS market and expect to have closed all of the US portfolio securitized by year-end. The refinancing of higher cost unsecured debt with ABS financing allows us to boost access to financing markets at a cheaper cost of debt capital as well as diversifying and segregating our balance sheet between our operating company and our Financial Services business. Bottom line, our improved free cash flow outlook and cash position ensures we have ample liquidity available to run our operations, continue to invest in our business, drive growth and execute on our strategy.

Now turning to our outlook on Slide 10. I am very pleased to announce that we are once again raising our full year guidance to reflect the continued momentum in the demand environment and our strong operational performance today. This will be our third guidance increase in SAM in October 2020. We now expect to grow non-GAAP operating profit by 25% to 35% and deliver fiscal year '21 non-GAAP diluted net earnings per share between $1.82 and $1.94. This is a $0.09 per share improvement at the midpoint of our prior EPS guidance of $1.70 to $1.88 and a $0.22 per share improvement at the midpoint since SAM.

With respect to supply chain, we have executed well to-date with minimal impacts and continue to take proactive inventory measures where possible. We do see further industry-wide tightening and inflation persisting in the near-term, which has been factored in our outlook from both the revenue and cost perspective, but overall demand remains strong. From a top-line perspective, we are pleased with the momentum we saw in the first half and while we continue to see further demand improvement, we remain prudent as certain geographies continue to navigate the pandemic and we continue to observe uncertainties in the supply of commodities.

More specifically, for Q3 '21, we expect revenue to be in line with our normal sequential seasonality of up low-single digits from Q2. For Q3 '21, we expect GAAP diluted net EPS of $0.04 to $0.10 and non-GAAP diluted net EPS of $0.38 to $0.44. Additionally, given our record levels of cash flow in the first half and raised earnings outlook, I am very pleased to announce that we are also raising FY '21 free cash flow guidance to $1.2 billion to $1.5 billion, that is a $350 million increase at the midpoint from our original SAM guidance.

So, overall, Antonio and I are very proud of the progress we have made in the first half. We have navigated well through the pandemic and are exiting the first half with improved revenue momentum, strong profitability and robust cash flow.

Our growth businesses in the Intelligent Edge and HPC MCS have accelerated top-line performance. Our core business of Compute and Storage revenues are growing with improved margins. And our as-a-service ARR is accelerating. We've also continued to execute well against our cost optimization and resource allocation program, which has made us leaner, better resourced and positioned to capitalize on the economic recovery currently at play.

Now with that, let's open it up for questions. Thank you.

Question & Answers

Operator

[Operator Instructions] The first question comes from Wamsi Mohan with Bank of America. Please go ahead.

Wamsi Mohan - Bank of America - Analyst

Yes, thank you. And congrats on another beat and full year free cash flow raise. I was wondering if you can dig a little bit more into the guidance dynamics. You're guiding 3Q a little bit below the Street, 4Q slightly higher. Can you maybe address what the visibility you have into 4Q is and how much of supply chain impact are you baking in into 3Q, 4Q, is that both the demand and that - and the cost level? Thank you.

Tarek Robbiati - Chief Financial Officer

Yes, Wamsi. Hi, it's Tarek here. So, let me try and dissect the guidance we gave for Q3 and also the full year. So, putting things in perspective, first, you know we are raising our FY '21 EPS outlook by $0.09 at the midpoint to $1.82 to $1.94 based on our Q2 outperformance. And we feel very confident for the rest of the year. This reflects what we see as continued improvement in customer spending. But also, we want to remain prudent given the remaining pandemic and supply chain uncertainty. Specifically for Q3, it's important to note that we do expect revenue growth in line with normal FY '18, FY '19 sequential seasonality, up low-single digits. We anchored you on FY '18, FY '19 and not last year, because of the disruption we suffered in the supply chain last year. So it's better to look at it from an FY '18, FY '19 viewpoint.

You should expect that gross margins hold roughly flat relative to our H1 levels, near just under 34%. Opex should be up somewhat as we continue to make select investments, aligned to our strategy in key growth areas. And this is partially offset by further efficiencies we find. But most importantly, it is important that you know that OI&E will flip to an expense overall in the full year and therefore in the second half. OI&E in Q1 was a positive income, in Q2 was a positive income and now we are expecting for the full year '21 a $50 million expense, hence the guidance that we're giving you overall for Q3. You can expect that the tax rates will be unchanged at 14% like we said at SAM. And the net of all of this is that we expect our Q3 non-GAAP EPS to be in the range of $0.38 to $0.44. And we feel pretty comfortable about it.

Andrew Simanek - Head of Investor Relations

Perfect. Thanks, Wamsi. Can we go to the next question please?

Operator

Our next question will come from Matt Sheerin with Stifel. Please go ahead.

Matt Sheerin - Stifel - Analyst

Yes. Thank you. Just wanted to ask your take on the forward guidance, which implies the low-single digit sequential growth, following above-seasonal quarter in the April quarter, it sounds like backlog continues to be strong. So, are there particular pockets of areas where you're seeing a slowdown or maybe more cautious outlook on customers because they're still dealing with the pandemic issues?

Antonio Neri - Chief Executive Officer

Hey, Matt. I don't think Tarek has any comment. I mean, we see strong demand momentum right now. We quoted in our remarks that we're up mid-single digits and therefore we translate that conversion into revenue. But obviously part of the improvement could come from the HPC acceptances, remember that on HPC orders to revenue is a little bit more lumpy because of the time between orders and revenue takes longer. But overall, what we are confident is the fact that we see obviously IT demand improving, but I'm really pleased with our innovation and our ability to execute against that innovation.

The innovation we have across the portfolio is perfectly timed with what we see in today's environment. We live in a much more distributed enterprise. Obviously digital transformation is essential to operate in this digital economy. And the first step is connectivity. And I have to tell you, the Intelligent Edge business is absolutely incredibly strong. So, in actual dollars, almost 20%. We expect to continue to be super strong for the balance of the year into '22 honestly. And that's because we have a business of scale. You have a massive business of scale. And to give a point of reference, we already have 100,000 customers on that platform. We add 150 customers every day. We manage more than 1.1 million devices. And honestly, we actually manage data of 1 billion plus per hour, data points that comes through our cloud. And so, we expect that to continue to be very strong.

I think the core business has definitely stabilized and we see pockets of improvements, particularly with Storage. And then, the as-a-service will continue to stay strong. Again, we are cautious about the supply chain aspects of this. But we position ourself well for the second half. And that was all factored in our guidance, absolute growth factor in our guidance. That's why we revised the guidance.

Andrew Simanek - Head of Investor Relations

Perfect. Thanks, Matt, for the question. Can we go to the next one please?

Operator

Our next question will come from Katy Huberty with Morgan Stanley. Please go ahead.

Katy Huberty - Morgan Stanley - Analyst

Thank you. Good afternoon. My congrats on the quarter as well. I want to come back to just reconciling the improving growth trajectory in all of your segments with the second half EPS guidance that assumes well below normal seasonality or about 40% of EPS coming in the back half versus past years you typically have low to mid-50% second half EPS mix. I think I heard you mention supply chain constraints and being cautious around that and COVID in general, cost inflation investments you're making and then any dynamics. Can you just rank those? Well, first, did I forget any? And then, can you just rank those factors in terms of which are having the most impact on your back half EPS guidance? Thank you.

Tarek Robbiati - Chief Financial Officer

Yeah. Thank you, Katy. So, let me try and add a little bit more color to what we said already. So, first of all, remember, our cost optimization and allocation program. We exited FY '20 very lean and this has driven a very strong performance in Q1. At $0.52 per share, this is a level of earnings that was actually benefiting from the fact that we have very strong run rates entering into Q1.

In Q2, you saw that momentum continuing with the EPS that we posted at $0.46 per share, very comfortable with the level of investments that we are making. And this is also showing in the gross and operating margin expansion that we've demonstrated so far. So now, when you also look at how this translates into free cash flow, obviously we had a lot of free cash flow benefits in Q1 and Q2 as a result of the earnings strength and which translated into free cash flow.

But moving forward, what you have to factor into the guidance on earnings, is a fact that there is some degree of uncertainty on supply chain. Although as Antonio said, the demand is very strong across the Board. The demand is very strong in Aruba, the demand is very strong in Compute and you can see that with units going up year-over-year. And also in HPC MCS, we are seeing the revenue trending in the range that we guided at SAM. This is all good.

Having said that, we have also to reckon two other dynamics. Aside from the cost optimization program and the demand, the other dynamic is OI&E which affects EPS in Q3 and Q4. Q1, Q2, we had two income quarters as far as OI&E is concerned, they flip into an expense of $50 million for the full year, gives you an order of magnitude of what would be the EPS for each one of Q3, Q4.

And then, on free cash flow, the other final element that drives it is, we have to deal with supply chain and we continue to buffer inventory to be ready for the demand in fiscal year '21 for the second half, but also fiscal year '22. We do not expect that the situation on inventory is going to be all of a sudden setting up across the world and across industries. And we've taken steps and we'll continue to do so.

So overall, we are managing, I would say, the resurgence demand environment very well. We are lean from an organization standpoint, our earnings power is shown by the margins we are posting. And also, you can see that what we're doing on free cash flow, we're doing very, very well. So hopefully that gives you a color to your questions with the rankings of the various effects at play.

Antonio Neri - Chief Executive Officer

Katy, this is Antonio. I just want to reinforce a couple of things. I understand, the normal sequential seasonality people trying to get into it. But the fact of the matter is, we have delivered record-breaking gross margin. We are raising our EPS guidance despite the supply chain uncertainty. And our business is in huge demand and it's not just the IT demand, it's the fact that we have a unique portfolio edge-to-cloud that's meeting the customer needs of today and future-ready for tomorrow.

So, I think the fact is that, when you look at the full year, right, we have raised guidance now three times and to Tarek's point is more than 25% from the beginning of the year and that's a testament of the momentum we have in the business. Then obviously every quarter has ups and downs because of unique things like OI&E or maybe more inventory build up, but in the end, the takeaway is that, we are raising again the EPS for the full year and free cash flow.

Andrew Simanek - Head of Investor Relations

Great. Thanks, Katy. Can we go to the next question please?

Our next question will come from Kyle McNeely with Jefferies. Please go ahead.

Kyle McNeely - Jefferies - Analyst

Hi. Thanks very much for the question. I wanted to see if you could give us a sense for the position of your Compute installed base. We saw F5 had stronger than expected upgrade activity to hardware systems coming out of the worst days of COVID impact. For you guys, how high is the average age of your Compute installed base versus normal levels? And are you seeing any upgrade activity start to come through now for on-premise hardware after COVID-related delays last year?

Antonio Neri - Chief Executive Officer

Well, sure. Obviously we are one of the market leaders today in terms of whatever you look at revenue market share, but obviously our portfolio, which is pro-Alliance, is on the 23 years in the making and our installed base is incredibly large. The average is probably between four or five years, Kyle, at this point in time. Definitely it's a pent-up demand to modernize that infrastructure. But it's not just replacing hardware for the sake of replacing hardware, it's to really bring the cloud experience to the computer source and more and more be able to consume it elastically as-a-service.

And that's the unique value proposition we have, which is not only just the best infrastructure with ProLiant as a franchise, but the fact that we have provisional lifecycle management and you just stay tuned for more announcement here shortly, but also be able to pivot that installed based to more a consumption base over time. And then more and more as a workload-optimized solutions. And remember, these platforms come also in a different structure, in the sense that you have more options and more technologies built into the platform. And so, for us it's a big opportunity. And I think, an accelerator of that position is our GreenLake business. It's not just replacing the old infrastructure or the capex [Phonetic] but be able to bring and repatriate workloads on-prem, what it makes sense, or actually hold workloads on-prem because now we can deliver a true cloud experience in our consumption-driven model.

Tarek Robbiati - Chief Financial Officer

Yeah. Let me add to this, Kyle. There is also another aspect to it. We see the pent-up demand and really the need to modernize the infrastructure and the way the infrastructure is used. But also, if the decision to actually modernize the infrastructure and moving to consumption isn't made, it's not bad for us, because we benefit from extended leasing with our Financial Services portfolio, which has been doing extremely well with our Asset Management business as people tend to use the infrastructure more, absent a decision or availability of supply for the equipment they want to use. So it's good for us on all fronts. And we're very happy with our performance on both the core Compute business and HP FS.

Antonio Neri - Chief Executive Officer

And last but not least, let's not forget, it's just the hardware, it's the operational services that come with it. Because every upgrade cycle, whether as a traditional way or as-a-service, our edge as-a-service is even better, because it comes 100% attach with Pointnext OS. We have seen richer configurations and higher services attached. And that's why part of the gross margin expansion you saw in Q2 in Compute, which was 550 basis points, comes also from the fact we are attaching more services to our infrastructure.

Andrew Simanek - Head of Investor Relations

Great. Thanks. Good question, Kyle. Could we go to the next one please?

Our next question will come from Aaron Rakers with Wells Fargo. Please go ahead.

Aaron Rakers - Wells Fargo Securities - Analyst

Yeah. Thanks for taking the question and congratulations on the quarter and raised guide. One of the things that comes up obviously is your asset H3C. I'm just curious, any updated thoughts on how you are thinking about that put optionality, which I believe is expires in early '22? And how are you thinking about kind of the use of capital? Any kind of thoughts on more flexibility on M&A or any strategic thoughts on that front? Thank you.

Antonio Neri - Chief Executive Officer

Well, I will start and then Tarek will comment. Listen, we still have roughly a year to make the decision that would expire in May 2022. Let me remind everybody that obviously China is the second largest IT market and growing. And our setup is unique. It's unique in many ways to fulfill the needs of a unique market like China. And I think that joint venture with a partner has been incredibly successful driving shareholder values through H3C level and also through us, right, because obviously we collect dividends from that joint venture, but in a way to reach a market that's very hard to compete.

So, we will continue to relate what is the best use of that capital in the context of participating in China and we decided to take action what to do with that capital. But right now, we have not decided one way or the other one. We continue to explore what is the best return for shareholders and also to position the company for growth as we think about the future.

I don't know, Tarek, if you have any comments.

Tarek Robbiati - Chief Financial Officer

Yeah. You said it very well, Antonio. We have time to make the decision. The port expires in April 2022. So we have a little bit less than a year. And that is to sell all or part of our 49% stake in Unis. We feel that this is a stake that continues to accreting value. Just to put things in perspective for everyone on the call, in fiscal year '20 alone, the equity interest contribution from HPC grew over 20% to $212 million for fiscal year '20. We expect that growth to continue and therefore the value of our stake to continue to accrete.

Andrew Simanek - Head of Investor Relations

Great. Thanks for the question, Aaron. Can we go to the next one please?

Our next question will come from Shannon Cross with Cross Research. Please go ahead.

Shannon Cross - Cross Research - Analyst

Thank you very much. I was going to ask about acquisitions in general and your M&A thoughts. It's been about a year since Silver Peak, a couple of years since now far. Just - I know you've made some small acquisitions in the interim, but I'm wondering, with the liquidity position you have, the cash flow and your approach to growth, where you're at and what you might think are some holes in your portfolio. Thank you.

Antonio Neri - Chief Executive Officer

Yeah. I think obviously M&A is an important component of our strategy. And as we have done - at least I have done now probably 19 of them. As always [Phonetic], there have been about obviously very stringent return on invested capital, very disciplined in that approach. But it's always about bringing intellectual property and talent to accelerate our edge-to-cloud platform vision. Silver Peak was completed in September last year and now fully integrated into the business and now we start seeing the momentum in our Intelligent Edge business. And other ones we are doing along the way, particularly around data and software defined assets and so forth.

So, again, we continue to evaluate what is available there, notwithstanding the fact that we have to be incredibly disciplined. As you know, valuation seems to be a little bit too high for some of the assets. But again, if there is something out there that makes sense, we will evaluate it and we will take the right action. But again, it's an important component of our strategy going forward. I know we talk about the Aruba like types of things, but we evaluate everything, whatever is relevant for our strategy.

I don't know, Tarek, if you have any comments on that.

Tarek Robbiati - Chief Financial Officer

Yeah. Shannon, I mean it's very important to maintain discipline and focus in the context where valuations in some cases, particularly for some class of asset is a little bit exuberant. But if we can find two to three Silver Peak type of acquisitions, I don't think Antonio and I will hesitate a second to just go and press the button.

Andrew Simanek - Head of Investor Relations

Great. Thanks, Shannon, for the question. Next one please.

Our next question will come from Amit Daryanani with Evercore. Please go ahead.

Amit Daryanani - Evercore - Analyst

Good afternoon. And thanks for taking my question. I guess, I was just hoping if you could talk more about the Intelligent Edge performance. 17% growth, I think, is more impressive or better than what most of your peers have had on the networking side other than Arista maybe. So maybe you can just talk about what is driving the inflection of growth over here and what is the durability of the double-digit growth really as we go into the back half and beyond. That would be really helpful.

And then, if I could ask you to clarify this, because I may have missed it completely, why is OI&E flipping from positive in the first half to negative in such a big win in the back half?

Antonio Neri - Chief Executive Officer

Sure. I will start and Tarek will talk about the OI&E. I mean, obviously if you look about the way we operate and the growth in IoT and the need for connectivity, obviously it's continued to grow. Interesting enough, three years ago, I said that the enterprise of the future will be edge-centric cloud-enabled and data-driven. And it's playing exactly that way. Unfortunately through the COVID pandemic, we saw that acceleration. But when you think about digital transformation, right, obviously we live in a digital economy and the first step is to be connected. If you are not connected and not participating, that connectivity is not just any more users and devices, it's things. Everything is connected to the network, everything computes, everything generates data.

And so, connectivity is at the forefront of the digital transformation.

And obviously, remote working is required, the need for WiFi connectivity to a level we haven't seen before. But that's an example of what's happening out there. But I will say, our innovation with a true cloud-native platform at massive scale. And again, the fact that we already have 100,000 customers and we are adding 150 customers every day, that tells you the value proposition resonated. We can provision a WAN port, a LAN port or a WiFi port or a BLE or a Zigbee, whatever is the protocol from the cloud. And we're able to do that in an intelligent and an autonomous way, because ultimately it's about the data you collect and what experiences you can provide.

And so, we believe this is absolutely durable. We are very bullish about this business. We expect this business to continue to grow double-digits for the balance of the year. And as we add more functionality, that cloud platform, particularly with edge computing and 5G, we are going to accelerate that momentum. And when you talk to customers and partners, they love the Aruba experience, absolutely love the simplicity, the law of the fact that you prove that experience for their own business and then powers this new way to work. So that's why we are very excited.

And the other thing is that the platform that Aruba runs the cloud is not the platform we run the rest of the company. When we deploy now one of the data services through the new announcements we made on May 4, where we deploy Compute or we deploy a workload-optimized is running on the same back-end that Aruba was originally created. And that's why we have a true edge-to-cloud platform. And then, we lay on top of that the as-a-service model, whether it's subscription software, which is growing triple digits in Aruba or whether it's the as-a-service model with GreenLake. And that's a unique differentiation we have in the marketplace and that's why we feel very good about the growth prospects of this business.

Tarek, on OI&E?

Tarek Robbiati - Chief Financial Officer

Yes. Thank you, Antonio. On the OI&E front - thanks for asking the question as to why we expect OI&E to flip into an expenses in the second half. In OI&E, you have effectively three effects. The first one is the H3C economic contribution and the timing of which shifts between quarters, while we're, like we said before, very happy with H3C and the economic interest that we have through them and the cash they return to us on a regular basis. So it's a timing element there for H3C.

There is also interest expense that is the second force in the OI&E line. And then the third force is the Pathfinder portfolio, our venture portfolio, which has been doing extremely well in the first half. And we did flag this in my script. We said we had benefits from revaluations of our investment into ECT and IonQ. We had, in the first quarter, OI&E a $16 million income, in the second quarter a $27 million income, this is on an aggregate basis across the three forces. So, for the first half, $43 million of OI&E income. And we're guiding for the full year for an expense of $50 million. So that's a $90 million swing. And that $90 million swing, if you turn it into a EPS number, divide that, you do the math yourself, is about $0.07 to $0.08 of EPS for the full year, right.

That's the thing you have to reckon when you compute your Q3 or Q4 EPS forecast that the swing factor there, it does not change the fact that our operating performance remains very, very solid. The swing factor at the OI&E level is explaining a little bit more hopefully the guidance for all of you on the call.

Antonio Neri - Chief Executive Officer

And I will say again, despite all of that, we are raising guidance.

Andrew Simanek - Head of Investor Relations

Great. Thanks for the question, Amit. I think we have time for one last question, please.

Operator

Yes. Our final question will come from Sidney Ho with Deutsche Bank. Please go ahead.

Sidney Ho - Deutsche Bank - Analyst

Thanks for taking my questions and congrats on solid results and cash flow. My question is on the HPC business. I had expected that that business grows sequentially, especially after a slowdown in Q1, maybe it's just normal seasonality, but understand the businesses could be lumpy. Are there any trends that you can draw from the last two quarters? What are the deals that are taking longer to close or being accepted by customers? And more broadly, what gives you confidence that you can hit your 8% to 12% growth target? Maybe you can talk about what's normal seasonality for that business in fiscal Q3 and fiscal Q4. Thanks.

Antonio Neri - Chief Executive Officer

Let me start. I'm going to talk more for the market, Tarek, can talk more on the financial side. Listen, the bookings momentum is incredibly strong in this business. So you have to look at the booking side and then you have to look at the revenue side. The bookings continue to be just amazing. And I call that some of the deals we want, these are multi-million dollar deals. Seasonality in this business doesn't really play out that well, because the fact of the matter is that, you have these large systems that need to be built, shift, installed, you have to run the workload and then - only then when the customer sets the system with the workload run, you can recognize revenue.

And that time can vary. It can be as quick as three months or as long as a year, in some cases, especially when you deploy this massive exascale systems, which we're going to do starting end of the year and then next year in 2022. And sometimes you need to run the workload for a month, but re-installing the system from the factory on the floor sometimes could take up to 60 days. Just it's the size of a football field. So, I would not think about the seasonality, I think about the long-term growth of the business we feel pretty good and confident about that CAGR. But even this year, we believe we are going to deliver the 8% to 12% growth just this year in 2021, right.

So this is about keeping up this growth momentum, short-term the lifecycle of the supply chain and install in acceptance as much as we can. And then, this business is a little softer that gets built around the system itself. So that's why we are very bullish about the system - this business. And that is all on the back of the data, that's why we talk about AI, deep learning technologies, data continues to grow exponentially. And you need more compute, that's a fact, at the level you haven't seen before.

Tarek, maybe want to comment on the…

Tarek Robbiati - Chief Financial Officer

Yeah. I think you said it very well, Antonio. Simply say, look, the order momentum remains very, very strong. It was up double digits in Q2. We have a large awarded order book with over $2 billion of contracts. The pipeline that we are having in mind includes another $5 billion of exascale opportunity to be awarded over the next three years. The win rates that we observe are very high, we win five out of six contracts in the exascale space. It's an inherently lumpy business.

So, I think if you look at it on a quarterly basis, probably not the best picture, you have to look at it on a multi-year basis. And we feel very confident that we can achieve the 8% to 12% CAGR per year, including starting this year, fiscal year '21. And because of the lumpiness of the revenue, you also have lumpiness in profitability as a result of the revenue profile and the product mix, that doesn't worry us at all, it's the nature of the beast, so to speak. We feel that HPC MCS is extremely well positioned as a business segment to continue to be a very strong tractor of growth for HPE overall.

Antonio Neri - Chief Executive Officer

And that growth will continue, which as I said earlier, right, today the HPC and the edge represent 22% of the company's revenue. And as we got forward, with both businesses growing double-digits, that 22% will be bigger, at the different margins in the court, right. So anyway, I know we are running out of time.

Just to close, I'm very pleased with HPE's Q2 results, that again that were marked by strong revenue momentum, our profitability and free cash flow. The overall demand is improving, but our execution, our innovation is perfectly timed to the customer needs, that we see in the marketplace and despite there is supply chain uncertainty around specific commodities, we factor all that in our ability to execute on the back half and that's why we are raising once again, for the third time in the year, our EPS and free cash flow.

And I believe, the future is edge-to-cloud and it's going to be consumption-based. Well, I think HP has unique value proposition and set of offerings. And that's why, I believe, this is a very exciting time for HPE. We have worked really hard. Despite the pandemic, our team has been incredibly resilient and this company has a clear purpose to advance, that where people will work and despite the challenges, we continue to support the communities we are in.

So, again, thank you again for joining the call today. And I hope you continue to stay safe and healthy and talk to you soon.

Andrew Simanek - Head of Investor Relations

Thanks everyone. Operator, I think we can go ahead and close out the call.
