Earnings Call Analysis

Improved Guidance and Strategic Partnerships

The company has updated its Q2 '24 guidance with ACV billings between $295 million and $305 million, revenue from $545 million to $555 million, and non-GAAP operating margins of 14% to 16%. For the full fiscal year 2024, ACV billings are projected at $1.08 billion to $1.1 billion, with a year-over-year growth of 14%, revenue between $2.095 billion and $2.125 billion, indicating a 13% increase, and free cash flow of $340 million to $360 million. These numbers surpass previous guidance, reflecting solid growth despite elongated sales cycles and a maturing renewals business. Additionally, the company's first customer for GPT-in-a-Box—a Federal Agency—is an early sign of growth in their AI solutions market, signaling potential ACV uplift. Partnerships, like the one with Red Hat to offer OpenShift on their platform, display strategic alignments to contend with competitors and signify a strong ecosystem for modern app and infrastructure platforms.

Nutanix Surpasses Guidance with Strong Q1 Growth Amidst Steady Demand

Despite an unchanged uncertain macro backdrop from the previous quarter, Nutanix achieved solid first quarter outcomes, outperforming their guidance. The company experienced unwavering demand for its digital transformation and infrastructure modernization solutions, leading to record quarterly revenue of $511 million, surpassing the $2 billion annualized run rate for the first time. A notable year-over-year increase of 30% boosted the Annual Recurring Revenue (ARR) to $1.7 billion.

Federal Business and Global 2000 Wins Highlight Expansion and Client Trust

Their first quarter's performance was bolstered by strong showings in the Federal business segment with wins across several agencies, including expansion into the public cloud. Additionally, an exemplary win came from a Global 2000 Bank in the Asia Pacific region, which selected Nutanix as the sole provider for its modernization projects and data center expansions, indicating both the depth of Nutanix's infrastructure solutions and the level of trust that large, global customers have in the company.

Robust Product Enhancements and Partnerships Bolster Market Position

Nutanix announced significant enhancements to its cloud platform, particularly to improve defenses against ransomware attacks, reflecting their commitment to product innovation and security. Furthermore, industry recognition as a leader by Forrester Research emphasizes the company's competitive market position. Nutanix also highlighted progress with its strategic partnership with Cisco, which draws attention to their expansion strategy and ability to attract and convert previously undecided customers.

Financial Metrics Show Revenue Growth, Strong Operating Margin and Cash Flow

The company's non-GAAP operating margin for Q1 stood at 15.6%, substantially higher than the forecasted 9% to 11%, while non-GAAP net income reached $85 million, resulting in an EPS of $0.29. A significant outcome was the free cash flow for the quarter which was reported at $132 million, indicating a free cash flow margin of 26%, surpassing expectations and highlighting efficient booking and cash management processes.

Long-term Vision with Sustained Growth and Substantial Free Cash Flow Projected

Looking ahead, Nutanix has set a projected ARR compound annual growth rate of approximately 20% through fiscal year '27, along with the anticipation of generating $700 million to $900 million of free cash flow in the same year. This ambitious target reflects the company’s confidence in its long-term growth trajectory and its capabilities to generate significant cash flow.

Operational Highlights and Forward-Looking Guidance

Operational highlights from the quarter include exceeding the high end of the guided metrics and a 24% year-over-year growth in ACV billings totaling $287 million. The forward-looking guidance provided during the call suggests continued confidence in the company’s strategy and future performance.

[Rajiv Ramaswami, executive]

Thank you, Rich, and good afternoon, everyone. We delivered a solid first quarter with results that came in ahead of our guidance. The uncertain macro backdrop, that we saw in our first quarter was largely unchanged, compared with the prior quarter.

However, we saw steady demand for our solutions driven by businesses prioritizing their digital transformation, and infrastructure modernization initiative. And looking to optimize their total cost of ownership. Taking a closer look at the first quarter, we were happy to have exceeded all our guided metrics, we delivered record quarterly revenue of $511 million, exceeding a $2 billion annualized run rate for the first time. And grew our ARR 30% year-over-year to $1.7 billion.

We also had another quarter of strong free cash flow generation, aided by good linearity. Overall, our first quarter financial performance was a strong start to our fiscal year. Our Federal business is typically strong in our first quarter, and this one was no exception. We saw wins with several different agencies across all 3 of our expansion vectors, including additional capacity for existing workloads, capacity for net new workloads and adoption of additional portfolio products.

The wins also included expansion into the public cloud with NC2 and AWS. And our first win with a large existing customer for GPT-in-a-Box, our recently introduced turnkey solution for deploying generative AI. We view the breadth and diversity of our wins with this important customer, as a testament to our ability to expand within our largest customers.

Another notable win in the quarter was with a Global 2000 Bank in the Asia Pacific region. This customer who signed a significant expansion agreement, selected Nutanix as their sole platform for their future modernization initiatives and planned build-out of multiple new data centers. This was a departure from the historical dual vendor strategy. They chose our Nutanix Cloud platform, including Nutanix Cloud Management to run their containerized business-critical applications. leveraging its simplicity and building automation for Infrastructure as-a-service.

They also adopted Nutanix Database Service for managing and deploying their databases, throughout their organization. We see this win as a great example of our ability to partner with the largest and most demanding companies in the world as they look to modernize and grow their businesses.

Generating leverage from our partners, remains a key focus. And towards this end, I'm excited with the early progress we've seen with our recently launched Cisco partnership. This past quarter, our joint solution was made generally available to be sold by both sales forces. We also saw good customer interest and secured a few wins for this new offering. Which were conversions of customers who had previously been planning to purchase Cisco's HyperFlex.

While it's still early days in this partnership, I'm encouraged by what we've seen so far. Another positive development on the partner front, in the first quarter, was a significant expansion deal we signed with a North American Managed Service Provider or MSP. This partner was increasing its capacity to handle the expected growth of its Nutanix related business.

We see this win as reflecting the growing traction we are seeing with our MSP partners. On the product front, this quarter, we announced important enhancements to the Nutanix Cloud platform to strengthen its capabilities against a ransomware attack on unstructured data. These new features enable organizations to detect the threat, defend from further damage and begin a one-click recovery process. All within 20 minutes of exposure.

They build on the strength of the Nutanix Cloud platform to protect and secure customers' most sensitive data across clouds. These enhancements reflect our ongoing commitment to investing in our platform. In the past quarter, we continue to receive industry recognition for our Nutanix Cloud platform, being recognized as a leader in the latest report from Forrester Research in this area.

We view our position as one of only 2 companies, named as a leader in this report. As a reflection, offer strong competitive position in the market. Finally, it was a pleasure seeing many of you in person at our recent Investor Day. We were happy to be able to provide an update on our large and growing market opportunity to discuss our long-term vision of enabling portable applications and to provide targets calling for an ARR compound annual growth rate of approximately 20% through fiscal year '27 and generation of $700 million to $900 million of free cash flow in fiscal year '27.

We've received great feedback so far from our Investor Day and look forward to continuing to drive towards the vision and targets we share. And with that, I'll hand it over to Rukmini Sivaram. Rukmini?

[Rukmini Sivaraman, executive]

Thank you, Rajiv. I will first provide commentary on our Q1 '24 results, followed by the guidance for Q2 '24 and fiscal year '24. Q1 '24 was a good quarter in which we exceeded the high end of the range on all guided metrics. ACV billings in Q1 was $287 million, above the guided range of $260 million to $270 million and a year-over-year growth rate of 24%.

Revenue in Q1 was $511 million, higher than the guided range of $495 million to $505 million and a year-over-year growth rate of 18%. The outperformance was driven partly by stronger-than-expected performance from our U.S. Federal Government business, which grew significantly year-over-year in new ACV bookings.

Our renewals performance also continued to be good. ARR at the end of Q1 was $1.664 billion, representing a year-over-year growth rate of 30%. Similar to last quarter, we saw a modest elongation of average sales cycles, relative to the year ago quarter. Average contract duration in Q1 was 2.9 years, slightly lower quarter-over-quarter and largely in line with our expectations, due to the higher mix of U.S. Federal Government business, which typically has lower contract duration.

Non-GAAP gross margin in Q1 was 85.9%, higher than our expectations, due to higher revenue and a mix of factors leading to lower-than-expected cost of goods sold. Non-GAAP operating expenses were $360 million in Q1. Non-GAAP operating margin in Q1 was 15.6%, higher than our guided range of 9% to 11%, partly due to higher-than-expected revenue.

Non-GAAP net income in Q1 was $85 million or EPS of $0.29 per share, based on fully diluted weighted average shares outstanding of approximately 293 million shares. Linearity was good, and DSOs, based on revenue and ending AR were 24 days in Q1. Free cash flow in Q1 was $132 million, implying free cash flow margin of 26%, higher than our expectations, largely due to better-than-expected booking familiarity.

We saw a larger-than-expected proportion of Q1 bookings in the first 2 months of the quarter. And since our payment terms are typically 30 to 45 days, more of the bookings were billed and collected in Q1, than expected. We ended Q1 with cash, cash equivalents and short-term investments of $1.571 billion, up from $1.437 billion in '23.

Under the share repurchase program, authorized by our Board of Directors at the end of August, we began repurchasing shares in Q1, through a 10b5-1 plan. Given the timing of the authorization, we were in the market repurchasing shares for only a portion of Q1.

Moving on to Q2. Our guidance for Q2 '24 is as follows: ACV billings of $295 million to $305 million, revenue of $545 million to $555 million. Non-GAAP gross margin of 85% to 86%, non-GAAP operating margin of 14% to 16%. Fully diluted shares outstanding of approximately 297 million shares.

The updated guidance for full year fiscal year 2024, is as follows: ACV billings of $1.08 billion to $1.1 billion, representing year-over-year growth of 14% at the midpoint of the range. Revenue of $2.095 billion to $2.125 billion, representing year-over-year growth of 13% at the midpoint. Non-GAAP gross margin of approximately 85%. Non-GAAP operating margin of 11.5% to 12.5%. Free cash flow of $340 million to $360 million, representing free cash flow margin of 16.6% at the midpoint of the range.

This updated fiscal year '24 guidance is higher than our previously provided fiscal year '24 guidance, across all metrics. I will now provide some additional commentary regarding our fiscal year '24 guidance. First, we are seeing continued new and expansion opportunities for our solutions, despite the uncertain macro environment.

However, as we mentioned previously, we have continued to see a modest elongation of average sales cycles. Our fiscal year '24 new and expansion ACV performance outlook assumed some impact from these macro dynamics. Second, the guidance assumes that our renewables business will continue to perform well.

And a reminder that while our available to renewal or ATR pool, continues to grow year-over-year. It is growing at a slower pace in fiscal year '24, but is expected to reaccelerate in fiscal year '25, based on our current view. Third, the full year guidance assumes that average contract duration would be flat to slightly lower, compared to fiscal year '23. As renewals continue to grow as a percentage of our billings.

A reminder that the full year ACV billing is not the sum of the ACV billings of the 4 quarters, due to contracts with durations less than 1 year. We expect full year ACV billings to be about 5% to 6% lower than the sum of the 4 quarters ACV billings.

Finally, a few thoughts on seasonality for the remainder of the fiscal year. Based on our current view, we expect the trend in top line metrics in Q3 relative to Q2, to be more or less similar to what we saw in fiscal year '23. A reminder that operating expenses tend to be slightly higher in Q3 versus Q2, all else being equal, as Q3 includes the full impact of calendar year resets to payroll taxes.

In closing, we are pleased with our Q1 results exceeding guidance and to raise our top line and bottom line guidance for the full fiscal year. With that, operator, please open the line for questions.

[Operator]

[Operator Instructions] And our first question for today will be coming from in Pinjalim Bora of JPMorgan.

[Pinjalim Bora, analyst]

This is Pinjalim, congrats on the quarter, guys. Rajiv, I was surprised to hear your first customer for GPT-in-a-Box. So, that's what I'm going to ask. What -- maybe add a little bit more color around what this company is doing with GPT-in-a-Box? Is this more of a test dev kind of an environment? Or are they looking to actually do something in production using GPT-in-a-Box? Are you seeing similar deals in the pipeline? How should we think about uplift in ACV? A number of questions, just surprised to see a new customer signing up so quickly.

[Rajiv Ramaswami, executive]

Yes, Pinjalim, so thanks for the question. It's still early days for GPT-in-a-Box. We're actually -- we've seen good inbound interest from customers, as well as prospective ecosystem partners. Now we did land that first win for GPT-in-a-Box. It is a Federal Agency. And the use cases are along the lines of what we've talked about. A lot of use cases have to do with document, sell documented that we were looking for patterns, looking for potential criminal activity, et cetera, right?

And that's along the line for what this particular agency was looking to do. Now from an offering perspective, it's still very early days for us. It's still early to really comment on when it's going to be a meaningful contribution to our numbers. At this point. And so that's what I can say about GPT now. Perhaps it might be worth recapping a little bit on a broader basis of how we see this market for us, that makes sense.

So for us, I look at AI, I've sort of said this at our Investor Day, but there's 3 parts to it: first is landing new applications. Lots of companies looking at new applications like this particular customer and many others. Lining that on our platform. And there, again, I think AI applications are going run around where the data is. And some of the data will be in the public cloud, but others are going to be sensitive. They're going to be in the private cloud in secure locations, for example. And -- and for those types of situations, we can help with our GPT-in-a-Box platform to provide a turnkey solution for them to both fine tune and train model from their specific data, as well as do inferencing. That's the first piece in terms of landing new applications.

The second is, of course, about making our own products better. And we do, for example, a lot of telemetry that we gather from customers and we can use back-end AI to analyze that, get insight. We have a product around operations management. In fact, that product will call AI Operations. And so again, there's a lot of AI behind it to make the operating environment and optimize the operating environment such as capacity planning, et cetera. So that's the second vector.

And the third vector is really using it internally itself to make things more efficient and run us more -- automate more processes inside the company, we are starting that out, for example, with customer service on our end. So that's a broader picture. Still early days for us with Gen AI. But again, lots of interest and we'll continue to engage.

[Pinjalim Bora, analyst]

Understood. One follow-up. We -- in the channel, we have been hearing that Red Hat has kind of thrown its hat on for the VMware opportunity with OpenShift virtualization technology, you obviously have a strong partnership with Red Hat. How do you kind of see that competition play out as both of you kind of go after the VMware opportunity.

[Rajiv Ramaswami, executive]

Yes. In fact, I mean, I think the -- this was actually the original thesis for the Red Hat partnership, that we complement each other very well they, from an OpenShift perspective, being -- providing a complete platform for modern app development and b, being the underlying infrastructure platform. .

And so from their perspective, as they compete against VMware on the application side, we compete with VMware on the infrastructure side. So the partnership was very good from that perspective, good synergies on our side. Now we have seen several customers adopt OpenShift on top of Nutanix, that continues. And we've seen G2K wins here as well with including G2K banks, for example, running OpenShift on the Nutanix platform.

So it's a good synergistic relationship. We look forward to doing more with them. So in fact, this particular D2K bank in Asia Pacific, that I mentioned, was a good example where they're running OpenShift on top of our Cloud platform.

[Operator]

And today, our next question will be coming from Jim Fish of Piper Sandler.

[James Fish, analyst]

Just wanted to build off the last one and ask it a little bit more directly. You guys have talked about like a little bit of VMware contribution here this quarter. But -- maybe you could walk us just through the pipeline. What does the pipeline look now that the competitor's acquisition has officially closed over to Broadcom and you've actually already seen them from what we've heard in our channel shacks at least. About them kind of raising maintenance prices pretty significantly. So can you just walk us through a little bit more detail on what you're seeing on the VMware pipeline itself going forward outside of just the Red Hat opportunity?

[Rajiv Ramaswami, executive]

For sure. Jim, good question. And of course, very relevant, given what just happened with the transaction closing. So even this last quarter, we did close some additional deals that I would consider to be implemented by the Broadcom BM transaction.

In fact, again, going back to that bank win that we talked about, the G2K Bank, that was certainly influenced by this transaction. As we mentioned, it was a dual vendor strategy, but going forward, it's going to be a single vendor strategy with us. Now the timing and magnitude of these deals is unpredictable. And also attributing the primary motivation for the deal also can be a bit nuanced because we compete every day, right, even before all of the acquisition news. So -- but they certainly is contributing.

Now the transaction, of course, closed recently, but we don't expect that to have an immediate impact for us in terms of timing of potential risk. Clearly, some many customers have signed multiyear ELAs with VMware, prior to the deep closing. And for those that have signed that gives them some time to evaluate options going forward. There continues to be certainly a lot of concerns around all the stuff we've talked about in the past, pricing, increased pricing potentially dropping support levels, et cetera.

So we have a significant pipeline of opportunities, and it's growing and a good degree of engagement with prospects driven by these concerns. It's just difficult to predict timing and magnitude of events. And we continue to expect some benefit from these influenced by this transaction, and we certainly factored that in into our guidance for this fiscal year.

[James Fish, analyst]

Very helpful. And a surprise to hear a little bit about the Cisco partnership already picking up. I mean we're 2 months in. Understanding it's easier with the installed base of HyperFlex to kind of sell or sell into that base. But -- any way to think about if there are larger periods of renewals at certain times within that base? Or if those renewals are accelerating, understanding, you mentioned that the larger the wins there were more on the kind of customers evaluating HyperFlex and you guys get substituted in.

[Rajiv Ramaswami, executive]

Yes. I mean, first of all, I think we're happy that we are -- our joint solution with Cisco became available this last quarter. So it's now in the field, both sellers are selling it. And those deals -- the initial deals, of course, naturally are ones where Cisco was either had already won them or was very close to winning them with HyperFlex, and now they're simply converting those over to Nutanix going forward. So that's one of the first part.

But with respect to new pipeline, really, I mean, we know that our pipeline takes 6 to 9 months to go close deals for us, right? So we don't expect a huge amount of Cisco this year. We expect some and we factored that into our guidance this year. And then we expect that to continue growing next fiscal year and beyond.

[Operator]

Our next question will be coming from Matt Hedberg of RBC Capital.

[Matthew Hedberg, analyst]

And I'll offer my congrats as well. Really solid quarter and guide, especially given the uncertainty of the macro environment. Rukmini, I have a question for you. You noted strong renewals in the quarter and obviously, it's becoming a bigger part of the mix. On the call, you talked about some new wins as well. But I'm curious, can you just step back and maybe double click a little bit more on the new business side of it. I know that, obviously, it's been more of a renewals business of late. But just where are we in the new business sort of aspect of the story?

[Rukmini Sivaraman, executive]

Matt, thank you for the question. So if we think about Q1, I'll talk about Q1 performance versus maybe what you were alluding to, but then also maybe talk a little bit about the full year, Matt, to your point on just trends and so on. .

So in Q1, specifically, our overall sort of top line performance or outperformance really was driven by a combination of good execution across our new and expansion business. And within that, we talked specifically about our U.S. Federal business. Which had a really significant and nice year-over-year growth in new and expansion ACV bookings. So that was certainly something that we benefited from in Q1.

Now for the full year, Matt, we've talked about, I think, some puts and takes that we are factoring into our outlook. One is that we are expecting some improvement in our new and expansion ACV performance, compared to fiscal year '23. We've talked about, Rajiv just touched upon like some things that we're factoring in, in terms of benefits, whether it be a little benefit from our -- from what's happening in the competitive environment, some benefits from the fairly new Cisco partnership and so on.

So we have some things that we're optimistic and excited about. At the same time, as you started your question, Matt, there is also uncertainty in the macro. Which just means that it's harder for us to sit here and say exactly how the rest of the year is going to play out. So those are some of the things we've factored into our new and expansion performance for the year.

I will say, I think as you pointed out, right, renewals tends to be much more predictable portion of the business, just given our GRR, as you said before, is in the 90-plus percent range, and we know when those renewals are coming up for the next transaction. And so that part continues to be predictable and continues to perform well. And so hopefully, that gives you a sense of revenue and expansion.

[Matthew Hedberg, analyst]

Super helpful. If I could ask one more. The gross margin performance has been great. And obviously, you guided to a really strong Q2 gross margin. Maybe could you double click there also, like what are some of the biggest factors driving that significant gross margin improvement?

[Rukmini Sivaraman, executive]

Yes. So I think a couple of points that I would make. Again, I'll start with sort of the Q1 and maybe the Q2 guide, Matt, and then talk more broadly on gross margin. So for Q1, we attributed our gross margin outperformance revenue coming in slightly higher, of course, because we beat on revenue.

But we also had a mix of factors that led to COGS coming in lower. Now there were a few things in there, Matt. I think that I would call out as one singular factor but a mix of things, some of which we believe will sustain and which is why we were happy to take up our full year gross margin number, last quarter when we gave you the first guide, we said approximately 84%, and we're happy to take it up to approximately 85%.

So I would say it's just a mix of good execution on a few different funds, and I reminded that our COGS has a good portion of it is our support teams like for our customer support folks are in there. We have services costs in there. And so across a few different dimensions, we were happy to see gross margin do better and take some of that across to the full year guide as well.

[Operator]

Our next question will be coming from George Wang of Barclays.

[Unknown Analyst]

Congrats on the quarter. So 2 quick ones. Firstly, just given better-than-expected free cash flow generation, just given kind of you guys started purchasing stocks. Just curious kind of any high-level plan going forward, how to model in terms of the share buyback, just given better free cash profile?

[Rukmini Sivaraman, executive]

Hi George, thank you for the question. So as I mentioned in my prepared remarks, we did begin repurchasing shares in Q1, under the authorization of -- that we had from our -- that was approved by our Board in August. And we did that through a 10b5-1 program that we've set up.

Due to the timing of the authorization, we were only in the market for a portion of Q1. And you'll see in the financial tables that we put out with the release that we spent about $17.5 million, repurchasing shares, during that time. So for a portion of Q1, we spent $17.5 million. And the timing and amount of the future repurchases will continue to depend on a variety of factors, George, including stock prices, just conditions in the market and so on. And so I won't get too specific in terms of outlook, but I wanted to give you at least a bit of color on what we did in Q1, acknowledging it was only for a portion of the quarter.

[Unknown Analyst]

Okay. Great. Just a quick follow-up, if I can. Just can you kind of comment on backlog? Last quarter, you talked about backlog slightly improved in absolute dollars year-over-year. As you kind of factored into the FY '24 guide. Just curious if you have any latest update in terms of the backlog level and any sort of close to minus, how would that factor into the latest guide?

[Rukmini Sivaraman, executive]

Yes, happy to give you some color on that. So we used some backlog in Q1, as is seasonally typical for Q1 and expect some backlog to be consumed over the course of this fiscal year, as we talked about before. But as is to be expected in an environment like this, where things remain fairly uncertain from a macro perspective, the range of possible outcomes is wider than usual.

And as we continue to grow, the absolute dollar number of backlog would also increase over time. So a few different factors there. But yes, I think in Q1, we used some backlog as is typical for Q1, and we expect to use some backlog over the course of the year as well.

[Operator]

Our next question will be coming from Michael Cikos of Needham.

[Michael Cikos, analyst]

Congrats on the strong quarter, wanted to cycle back to some of the comments when we're describing the revenue and the ACV billings outperformance. I know that we cited specifically U.S. Federal. Can you give us a better sense, as far as what U.S. Federal is as far as size or contribution to revenue or ACV billings? Understanding that there's probably seasonality with their year-end. But would just be good to get a flavor for how big of a component that is to the overall business?

And then also, if you could shed some light, I know that you cited the improved linearity during the quarter. Is it -- is that improvement are tied back to the stronger U.S. federal business? Or is it -- are those 2 independent items in your view?

[Rajiv Ramaswami, executive]

So I can take a first crack at the Federal piece, Rukmini you can go for the rest. So what I say is, look, lastly, we don't have verticals, but we have 2 exceptions. And that's in the U.S., we have Federal at verticals, and we have Health Care as another vertical. So from that perspective, Federal is a significant portion of our business. We haven't broken it out exactly in terms of the percentages. But given the fact that it is 1 or 2 verticals and we have a focused team on it, it is important for us. And of course, there's also seasonality there. as Rukmini was alluding to here. I mean this quarter typically is strong for Federal. So that's kind of what we have to say about Federal, Rukmini, you can comment on the linearity.

[Rukmini Sivaraman, executive]

Yes. So on the linearity, Mike, what we mean there is we have some expectations of how much bookings comes in, in month 1, month 2, month 3. And the reason that's important for free cash flow, right, is because we invoice soon after we get the booking, and we have 30- to 45-day invoice payment terms. And so what we saw in Q1 is that compared to our expectations going in.

So we saw a larger proportion of those bookings come in month 1 and month 2. And you're right, there's been outperformance spread as well. And of course, Fed had their year-end, the U.S. Federal Government has their fiscal year end in September. So that was likely a factor in that. And so what that meant was that given, again, we invoiced right after we get the bookings, we were -- we collected more cash from bookings in Q1 than we had previously expected, which was a significant driver of the free cash flow performance in Q1.

[Michael Cikos, analyst]

Understood. I guess -- the other question that I had, this is more specific to the 2Q guidance that we have here today, Rukmini. But if I could just take a look, I'm happy to see that the revenue is coming in above where the sell side models were happy to see the strong gross margins and then the operating margin is also coming in ahead of where we had been.

But one of the things that I'm looking at is the OpEx, the implied OpEx from Q1 to Q2, has a pretty material pickup after being relatively flat the last couple of quarters. And I just wanted to see what is it that you guys are embedding in that? Is it more maybe targeted go-to-market initiatives? Are you focused on hiring or potentially backfilling open positions? Like how should we think about that OpEx ramp that you guys are putting now in the 2Q guide?

[Rukmini Sivaraman, executive]

Yes. So a few points on Q2 OpEx related to Q1, Mike, the first one is, as we talked about when we laid out sort of our initial full year guide on the last call, we talked about the fact that we plan to continue to invest to drive growth, while continuing to improve the margin profile. And that's the approach that we've taken for this year, and you saw some of that in the last call, but also we touched on this sort of idea at Investor Day as well.

And so in general, we've started those investments. And as you can imagine, it takes -- we're continuing to hire. And so as you can imagine, that sort of leads to sort of an increase in Q2 as more of the folks come on board. The other piece is this is only for 1 month of Q2. But in the calendar year resets, and I alluded to this in my script as well, like payroll taxes and all that reset for calendar year '24, which means that we have 1 month of that in January. That also has an effect on the Q2 OpEx. That all said, of course, we were pleased, as you pointed out, to be able to raise both of our top line and bottom line guidance for the full year.

And the next question will be coming from Erik Suppiger JMP.

[Erik Suppiger, analyst]

Congrats, 2 questions. One, you said the sales cycles continue to elongate. Are they still getting longer? Or is it just they've kind of reached a level of extended cycles? Is it consistent with last quarter? Is it actually getting longer? And then secondly, you've had some time now to talk with customers about their chat GBT in the box. What are the specific use cases that customers are using either what department are they using that for? Or how are they using that in particular?

[Rukmini Sivaraman, executive]

Thank you, Erik. I'll take the first one. Yes, and then Rajiv you can take maybe the GPT-in-a-Box question. So on sales cycles, what I said in my script, Erik, was that we're seeing some increased elongation, right, in a modest increase in average sales cycles on a year-over-year basis. In comparing Q1 to Q1, it has gotten longer in Q1. But if you look at average sales in Q1, it was more or less the same as the last few quarters. So it's not like it's continued to lengthen early quarter-over-quarter, but year-over-year, it remains elevated. And this -- again, it's hard to sort of focus what's going to -- exactly is going to happen here, given all the uncertainties we've talked about, but that's what we saw in Q1.

[Erik Suppiger, analyst]

Okay.

[Rajiv Ramaswami, executive]

So Eric, on the GPT. By the way, its GPT not Chat GPT. So on the GPT-in-a-Box section, there are 4 use cases that we typically see. And again, I want to caution all this by saying it's pretty early. A lot of people are just trying to figure out how to use GEN AI. But the 4 use cases right now. First, of course, is a classic customer service use case. That includes chat, that's one. .

The second is a whole bunch of operations having to do with documents, document search, document analysis, document retrieval of key information from unstructured data, for example. So that's the second big, I would say, a use case.

The third use case is co-piloting, generally providing assistive services, for example, to software developers or researchers and pharma for example. That's the third use case. And the fourth use case would -- I would broadly classify as fraud detection or fraud prevention. And these are things across multiple verticals. I think these tend to cut cost verticals, whether it be Financial Services or Retail or our Federal or [ water ].

[Erik Suppiger, analyst]

Last question is you talked about the class of customer service. Is that the majority of the use cases at this point? Or is it spread across those different 4 options?

[Rajiv Ramaswami, executive]

I would say it's spread across. It's -- now the customer service one, for example, happens to be one that we are ourselves internally trialing right now within Nutanix. But I would say it's fairly broad-based across all of those 4. And it's still very early, I have to say, to say, "Hey, we can actually say, "Hey, this presented one use case versus the other. It's just, we are in the forming stages here.

[Operator]

Our next question will be coming from Meta Marshall of Morgan Stanley.

[Unknown Analyst]

This is Karan on for Meta. So just first question, I understand it's sort of a challenging environment today. But I guess just in terms of customer conversations or what you're hearing from customers in terms of 2024 budgets, I guess what are you hearing from customers on those budgets? And are you seeing a pickup in any RFP activity?

[Rajiv Ramaswami, executive]

I wouldn't say there's anything specific we are seeing in our conversations with customers. I think, certainly, look, I would say they're still investing in their digital efforts in their modernization efforts. Every customer call I have, this conversation on how they can be using AI inside their companies.

So from a budget perspective, I would say, in general, I think IT spending will probably grow faster than GDP growth. And within that, I would say software modernization spending will probably grow faster than that. But we haven't seen any specific trend other than the fact that there are customers are still on us, at least, they're willing to spend the money. They want to make sure there's a solid business case and there's good TCO and ROI for everything that they do.

And there's certainly more inspection, which is what is causing the elongation in the cycle, right? They want to make sure there may be an additional level of approvals, for example, before they sign up on projects, but they're still moving forward with projects.

[Unknown Analyst]

Okay. That's helpful. And then a quick follow-up. Sort of at the Analyst Day, you mentioned some of the VMware share gains will that take place. With just a little bit of share with each customer over time. I guess as you started to see these opportunities take place, are these shares maybe -- are the share taking greater than expected? Or is it just more opportunities or more at bats. Or I guess just any color around sort of the opportunities you're seeing in share gains there?

[Rajiv Ramaswami, executive]

Yes. I think we commented on the overall situation from a VMware Broadcom perspective. Again, I think we are still at a point where we have a significant and growing pipeline of opportunities that we are engaged in with prospects. But it's hard to predict what portion of those will win? How much will they, for example, bring us in as a second vendor or the sole vendor or just users as a negotiating lever to get a better deal from VMware.

So there's a lot of uncertainty and lack of predictability there for the long term. So we've focused all the timing, for example, for when this might happen. So we -- that's why we have -- we've modeled in some level of share gains here into our forecast for the year and incorporated into the guidance. But it's going to be -- I would again emphasize that it's going to be a multiyear thing for us here. And it's going to be a bit timing and the exact share gains are going to be a little unpredictable.

[Operator]

Our next question will be coming from Ben Bollin of Cleveland Research.

[Benjamin Bollin, analyst]

Rajiv, I wanted to ask about the Global 2000 Financials Awards. Could you share a little bit about what that process looks like? How long was the evaluation, the pilot? And how does the ACV ramp for that deal? Does it build over time, as they get more data centers? Does it commence at a full run rate? Just any color on that? And then I have a follow-up.

[Rajiv Ramaswami, executive]

Yes. So this particular bank in Asia Pacific, the G2K Bank, has been a customer for a while for us. And what they've been doing, of course, is the classic, they've been migrating from traditional legacy 3-tier infrastructure over to HCI. And for many years, I mean, they've been a customer for a while now. And for many years, it was a dual vendor situation with us and VMware. And -- so they've been going on both parts. They had us, they had this. And this was a classic time, where we were coming due for renewal, and they were also looking to expand, significantly increase their presence, their growing and they had multiple data centers that they were going to go modernize.

So for them, this was a time for them to -- for us to do an expansion along with the renewal, a substantial expansion. And like we've said with other G2K customers, generally, once we get in the door, they're pretty happy with us, and they do expand with us over time. In fact, we've given you some data at Investor Day in terms of how much the expansion is like I think it was 25x or 26x over life.

So this particular bank was similar, right? They liked that. They were comfortable with us. And then now they have this additional trigger that they were concerned about what would happen on the other side. So when they did do the expansion with us, they went with us as a sole vendor. So that's sort of how it played out for us.

[Rukmini Sivaraman, executive]

I can add to that, Ben. I think you had a question on ACV ramp. And just to clarify,there are contracts, typically, they're sort of evenly spread up, there isn't a ramp within the year. So like this transaction and typically most of our transactions, it would be a total TCV amount divided by the contract duration. That's how we we calculate the ACB of any given transaction.

[Benjamin Bollin, analyst]

Okay. That's great. The other item, Rajiv, I'm curious, you talked about the MSP awards. Can you share any thoughts about your strategy around go-to-market efforts? Do you have some programs specifically geared to pursue more of these partners that are potentially alienate by this deal? That's it for me.

[Rajiv Ramaswami, executive]

Yes, I think that's -- again, that's both an MSP specific thing here and a broader thing here, as well in your questions and Ben. So on the MSP specific, I mean, for us, independent of the transaction. This was a an area that we want to do more in because traditionally, we have not had a big route to market through MSPs. So for the last couple of years, we've been building up our MSP presence and recruiting more of these to come on board as partners. And that continues. And this particular in the last quarter was a good example of an expansion opportunity where they had done something small with us and now the standard is a significant expansion with us. .

So I do think that with the transaction happening, it's not only the customers of VMware that are going to be concerned, but there's also their partners and that includes the MSP partners. So -- so we are talking to the MSP partners, just like people with other customers and trying to recruit more of them on to the Nutanix platform. And so this is still, I would say, we are young when it comes to the MSP route to market. And so there's potentially a lot more MSPs that we do need to recruit over time and get on board as our partners. And we have a team [ add ] Nutanix has focused on recruiting these partners and enabling that.

The next question is coming from Ruplu Bhattacharya from Bank of America.

[Wamsi Mohan, analyst]

It's actually Wamsi here at Bank of America. I guess, Rukmini, if you could address seasonality. Your Q2 revenue guidance at the midpoint is calling for 8% growth. That is the lowest that we've seen over the last 4 or 5 years, but you're calling for Q3 seasonality to be down similar to fiscal '23. Which is down the highest in the last several years. And I'm just wondering, are you seeing something around the macro that's causing you to view the seasonality this way, which is actually a little bit bias lower towards Q3 than historically, a little bit lower also in Q2 to the upside. Just wondering if you could share any color there.

[Rukmini Sivaraman, executive]

Wamsi, thanks for the question. So a few things I would say. One, on the Q1 to Q2 dynamic. We talked about Q1 of course, came in at a bit higher than our expectations, given the beat across revenue and ACV billings, one. So I think relative to that Q2, I think, to your point, still going to look based on our guidance, right, higher than Q1 as we seasonally see. I wouldn't read too much into that dynamic.

And then the reason we sort of gave the color on Q3 is to just note what we're seeing right now, based on pipeline and all the various factors we've talked about already. As it relates to things that are driving the top line. And I'll just remind folks, again, as we said in the prepared remarks as well that the full year ACV billings is at about a 5% or 6% discount with some of the 4 quarters given the annualization that we do each quarter for contracts less than 1 year.

So overall, I'd say, I think I wouldn't read too much into the seasonality point, other than we're seeing -- this is what we're seeing in our pipeline. I wanted to give folks an update on that. And overall, we're happy to be able to raise our '24 ACV billings guidance, right, following a solid first quarter, but we've also factored in some caution overall, regarding how the rest of the year plays out given some of this macro onset.

[Wamsi Mohan, analyst]

Okay.Okay. I appreciate the color. And -- and just on free cash flow to clarification. When you think about what you would have normally called a normal booking linearity in the quarter. What was -- what would you say is the delta of overachievement in fiscal 1Q? And is that overachievement primarily what's driving the full year free cash flow increase? Or are you expecting sort of is that free cash flow was beyond sort of the 1Q over achievement?

[Rukmini Sivaraman, executive]

Yes, great question, Wamsi. So 2 thoughts. So one on Q1, we, of course, don't guide to quarterly free cash flow. So I'm not able to sort of give you specifically how much we overachieved our own expectations for Q1 free cash flow, but we did overachieve it.

And I will say that, in addition to the billings number coming higher, right, given we had a beat on ACV billings as well for Q1. So that helped, but the linearity was a significant factor in Q1, okay? So that did have a a significant impact on the outperformance for free cash flow in Q1. And I think the second part of your question is around the full year free cash flow guidance.

And what I'd say there is that in addition to benefiting from the raised top line guide, and of course, as you know, billing has a very high correlation with free cash flow, right? So the fact that we were able to raise our full year billings number. So that's 1 factor. But we're also expecting to see some benefit from somewhat better working capital management within the year than previously expected. Including from improved linearity. So that is helping us to raise the full year free cash flow guide as well.

And the next question is coming from Simon Leopold of Raymond James.

[W. Chiu, analyst]

This is Victor Chin for Simon Leopold. Regarding the share shifts and competitive dynamics with VMware, are there instances where customers use both VMware and Nutanix?

[Rajiv Ramaswami, executive]

A lot of customers use both VMware and Nutanix. And again, I think just to clarify, how they use. Sometimes their users is just -- they have a dual vendor strategy. They'll do some of some. There's also -- we work together with Nutanix. I mean, Nutanix works together with VMware hypervisor, VSX, -- so we have a lot of customers who are deploying Nutanix on top of VMS hypervisor, VSX. And over the years, many of these have also migrated from ESX to our own billion hypervisor that's included in the platform.

In fact, again, I would say, over the years, we came up with our own hypervisor back in 2015. And today, if you look at our workload across the entire spectrum of customers, about 65% of those workloads have migrated and they are now on just a Nutanix hypervisor. Most of those 1 VMX high providers. But we are committed to continuing to interoperate very nicely with VMware. And so customers have the choice. They have our -- it's all about providing a premium of choice for customers. So we interoperate with them, we can replace them fully. It's up to the customer.

[W. Chiu, analyst]

Okay, okay. And are you having discussions with customers? Is your visibility kind of what -- into what their plans are going forward, kind of built into your assumptions and kind of the share shifts that come along with that, is that kind of built into assumptions or is there some dry powder that that potentially happens?

[Rajiv Ramaswami, executive]

Yes. Like we said, it's hard to predict the timing and how big these things are going to be, right? And so we have factored in some of this into our guide for the full year, and we'll have to see how things materialize. There's a lot of engagement, but what happens to these engagements from do we win them fully? Do we win partially or do we win nothing and just become a a leverage point for them to get a better deal on the other side. It's hard to predict ahead of time. So we have to see how it plays out. And it's hard to predict both timing and the degree to which they'll play out for each customer.

[Operator]
