Michael Burkland

Thanks, Emily, and thanks, everyone, for joining our call this afternoon. I'm pleased to report strong second quarter results with revenue growth of 18% year-over-year, primarily driven by our LTM enterprise subscription revenue growing 28% year-over-year. Also, we enjoyed a particularly strong quarter for new logo bookings, demonstrating the value of our Intelligent CX platform and our strong go-to-market execution. Adjusted EBITDA margin for the second quarter was 19% of revenue, helping drive a record Q2 for operating cash flow of $22 million or 10% of revenue.
Turning now to the 3 key trends that continue to drive our confidence in our market opportunity. First, Legacy vendors are retrenching, forcing enterprises to develop concrete plans with an even greater sense of urgency to replace their on-premise contact center solutions. Remember that in terms of cloud replacing on-premise, we believe the penetration is still less than 20%. Second, companies are enthusiastically pursuing digital transformation initiatives to enhance customer experience, cut costs and increase revenue. Third, AI is becoming a significant catalyst for enterprises to shift to the cloud. Regarding this third trend, given all the recent focus on generative AI, I would like to recap our perspective on its impact on our industry and, in particular, Five9.
We believe generative AI is the next wave of opportunity for Five9 with the potential to broaden our TAM. Five9 has been riding the wave of AI and automation for the past several years, and we feel we're well positioned to continue to push this industry forward. Not only is the AI revolution a tailwind to our technology and innovation but it's also a tailwind to our business. We provide software for enterprise clients to manage their customer interactions.
As AI drives efficiency and productivity gains in the form of a mix shift toward more automation of interactions, that leads directly to an increase in revenue per customer and a TAM expansion for Five9. AI and automation is clearly an area of focus for enterprises as demonstrated by our nearly 80% attach rate on $1 million-plus ARR new logo wins in the quarter.
Now I'd like to discuss what we view as the 3 main growth drivers for our business, namely our platform, our march up market and our continuing international expansion. Let's begin with our platform. Today, I'm pleased to announce an important extension of our Intelligent CX Platform as we have entered into a definitive agreement to acquire Aceyus, a market leader in advanced data integration and analytics.
We believe Aceyus will uniquely accelerate our ability to capitalize on 2 large opportunities: First, streamlining the migration of large enterprise customers from on-prem to cloud; and second, leveraging contextual data to deliver personalized experiences throughout the customer journey, including using this contextual data in our AI and automation solutions.
Let me elaborate on these one at a time. Let's start with streamlining cloud migrations. Using a robust catalog of prebuilt integrations, Aceyus software ingests data from CRMs, WEMs, multiple ACDs and many other systems. Aceyus' ability to normalize the entire data set allows the business to transition from legacy systems to Five9 while maintaining consistent reports, data visualization and dashboards. This enables customers to run their business smoothly and take advantage of the Five9 platform during the migration and beyond. In short, the continuity of data and insight provided by Aceyus across complex environments allows for smoother, large-scale cloud migrations with a faster time to value.
Now let's talk about the second opportunity, which is to leverage contextual data to deliver personalized experiences throughout the customer journey. This contextual data often lives in dozens of disparate and siloed systems. As a market leader in advanced data integration and analytics for large enterprises, Aceyus will further differentiate the Five9 platform as we integrate their robust prebuilt data integrations to expand our platform's data lake. Aceyus will enable Five9 to access this contextual data to optimize, predict and deliver the personalized journeys customers expect.
This applies especially to our AI and automation solutions, where the use of this contextual data is critical to the accuracy and efficacy required to deliver joyful customer experiences. Aceyus' customer base includes many Fortune 100 companies and joint accounts with Five9, including some of our largest prospects and customers, 2 of which Dan will talk about in a moment.
And now I'd like to focus on our march up market and international expansion. We continue to see accelerating momentum market with large enterprises adopting Five9 at an unprecedented rate. I'm pleased to report that we booked a Q2 record number of $1 million plus ARR deals, and Dan will discuss 4 such new logos, which alone represent approximately $42 million in anticipated ARR to Five9. As a reminder, $1 million-plus ARR customers make up more than 50% of our recurring revenue.
This march up market and our continued international expansion are accentuated by the strong performance from our ever-growing network of global partners and their commitment to leading with Five9. This was reflected by an all-time record for channel bookings; 15 partners that achieved over $1 million in ACV bookings in the quarter; a record high channel pipeline; and over 60% of international implementations now being done by partners. This global partner strategy is also paying dividends and helping us expand our international footprint.
For example, in addition to the recently announced BT partnership, in Q2, we also signed TELUS International as a strategic partner to Five9, which Dan will also elaborate on in a moment. Lastly, in May, we held our EMEA CX Summit in Porto, Portugal, the location of our new international development hub. I was personally blown away by the energy and enthusiasm of this event by our partners, customers, industry analysts and employees.
Before I turn it over to Dan, I want to spend a moment to share with you our recently refreshed and reenergized mission and vision statements for Five9. Our mission is to enable our enterprise clients to reimagine their customer experience by providing our intelligent CX platform combined with passionate experts to deliver joyful customer experience and better business outcomes. Our vision is to bring joy to CX. We often refer to this as Five9 Joy and it shows up in many forms from many stakeholders.
For consumers, it means effortless and fluid customer experiences. For our enterprise clients, it means better business outcomes, such as higher customer satisfaction, increased revenue, greater efficiency and lower costs. For agents using Five9, it means being armed with the knowledge, data, intelligence and automation to deliver great customer experiences. For supervisors and managers in the contact center, it means having the tools and applications to engage and manage their workforce. For our partners, it means providing technology and people that will drive success for our joint customers. And for our employees, it means living by our values every day, resulting in a unique and winning culture, filled with passion and purpose and one where we enjoy the journey together.
In summary, our goal was to bring Five9 Joy to all involved in CX as well as the entire Five9 community. And now I will turn it over to our President and CRO, Dan Burkland. Dan, go ahead.

Daniel P. Burkland

Thank you, Mike, and good afternoon, everyone. As Mike mentioned, we are seeing a renewed momentum on the net new side of our business, but we're still facing some headwinds on our installed base. The new logo bookings were an all-time high for any quarter other than the quarter we booked the healthcare conglomerate, indicating the strength and persistence of the 3 key trends that Mike talked about earlier. In addition, our pipeline reached another all-time high.
Now I'd like to share some examples of key wins for the quarter. I normally discuss 3 key new logos. Today, I'm going to share a fourth, given that we already disclosed the $8.4 million ARR regional bank Q2 win in last quarter's earnings call. The first is a Fortune 50 global health care insurance company providing coverage for medical, dental, disability and life.
Over the years through M&A, they had accumulated several disparate systems leading to tremendous inefficiency while also lacking the modern applications in automation. With Five9, they will enjoy a complete omnichannel experience that's fully integrated to the proprietary CRM and we'll integrate to their existing Verint solution using our voice stream API.
They also chose Five9 due to our Aceyus integration to do precisely what Mike described earlier, helping them make the transition from their legacy existing platforms over to Five9 while maintaining consistent reports, individualization and dashboards throughout that migration to Five9. We anticipate this initial order to result in over $20 million in ARR to Five9. The second key win I'd like to highlight is one we touched on last quarter, the regional bank, which booked at the beginning of Q2. They selected Five9 and will be enjoying a full omnichannel experience with deep integration to Salesforce, ServiceNow and Pega CRM and the full suite of Five9 WEM powered by Verint.
We also sold Aceyus for analytics and real-time dashboarding to collect and display information from several different data sources. In addition, they purchased our voice and digital IVAs as well as agent assist, which will provide real-time agent coaching and automatic retrieval of information to create a personalized customer experience. We anticipate this initial order to result in approximately $8.4 million in ARR to Five9.
The third key win is a healthcare company, providing operations, staffing, tools and technology to primary care facilities throughout North America. They had embarked on implementing a competitive CCaaS solution when they made an acquisition of a company who had recently selected Five9. The easy decision for them would have been to cancel the acquired company's Five9 contract and continue implementing with our competitor.
Upon further evaluation, they realized Five9 was the superior solution and we'll be using Five9 for the entire combined company. We will be integrating to their Salesforce, Epic and athena CRMs as well as using Five9 WEM powered by Verint. They also have purchased our IVA self-service solution for authenticating caller IDs, scheduling appointments, refilling prescriptions and paying invoices. We anticipate this initial order to result in approximately $8.3 million in ARR to Five9.
The fourth example, which Mike mentioned earlier, is TELUS International, where we entered into a reseller agreement. This agreement also included a replacement of their internal use legacy systems, which serve the BPO portion of their business. We anticipate this initial order to result in approximately $5.2 million in ARR to Five9. And now as I normally do, I'll share an example of a customer, who has expanded their use of Five9. This customer, who has been with us since 2017, is a network of independent healthcare providers focused on academic centers, acute care facilities and research hospitals.
Separate from their use of Five9, they had an ambulatory support center that was using a competing CCaaS solution which wasn't meeting their needs. They replaced it with Five9 and also added Five9 WEM powered by Verint and our IVAs. This will more than double their ARR spend with Five9 from approximately $1.2 million to approximately $2.5 million. So as you can see, we're continuing to see strong momentum on market replacing legacy systems, while enabling enterprises to deliver better experiences to their customers.
And with that, I'd now like to hand it off to Barry to take us through the financials. Barry?

Barry Zwarenstein

Thank you, Dan. We are pleased with our performance, with both top and bottom line results exceeding our expectations. Revenue grew 18% year-over-year, driven primarily by our Enterprise business, which now makes up 87% of LTM revenue. Our LTM enterprise subscription revenue which makes up more than 60% of total revenue, grew 28% year-over-year, in line with the high 20s outlook we have been communicating recently. We view the drop in the enterprise subscription revenue below 20% as transitory, driven by the subdued growth in our installed base. We believe we are well positioned to resume historic levels of growth in this part of our business when, eventually, macroeconomic conditions improve.
Our commercial business, which represents the remaining 13% of LTM revenue grew year-over-year in the high single digits on an LTM basis. Recurring revenue made up 91% of total revenue in the second quarter. The other 9% of total revenue was comprised of professional services. I will now give more color around revenue.
As Mike mentioned, the new logo side of our business, which strictly makes up approximately half of our year-over-year annual revenue growth continued to grow at a strong rate. The deployment of our 2 mega deals remains on track. We continue to expect the international operations of the parcel delivery company to be substantially deployed by the end of 2023. And the healthcare conglomerate to continue ramping throughout 2023, with full deployment in early 2024.
Additionally, our substantial backlog from other enterprise customers that are not yet generating revenue, provide us with good visibility. However, I would like to remind you that for the 4 deals that Dan discussed earlier, will not contribute meaningfully to revenue this year.
Now I'd like to turn to our installed base, which continue to be challenged by macro cross-currents in the second quarter with 1 vertical, in particular, facing the strongest headwinds, namely Consumer. As a reminder, Consumer is our third largest vertical and it declined sequentially this quarter by mid-single digits compared to mid-single-digit sequential growth in the second quarter of last year. This was primarily driven by customers in used order sales, auto parts, gifts, apparel and home improvement. The remaining 16 verticals in our installed base, in aggregate, grew sequentially at a similar rate as in the second quarter of 2022.
Our LTM dollar-based retention rate was 112%, a decline of 2 percentage points sequentially, mainly due to the ongoing macro headwinds causing subdued growth in our installed base. You should expect further minor weakness in LTM dollar-based retention rate until macro conditions improve. Longer term, we continue to expect our retention rate to trend towards the high 120s by 2027 due to a higher mix of enterprise customers, especially larger ones, which have demonstrably higher retention rate and higher ARPU from AI and automation and other offerings.
Second quarter adjusted gross margins were 61.8%, an increase of approximately 140 basis points sequentially and 110 basis points year-over-year. This is the first year-over-year expansion in adjusted gross margins since the fourth quarter of 2020. However, I would like to point out that given the record number of large new logo wins this last quarter. We are making upfront incremental investments to further scale professional services which may hinder our ability to continue to report further year-over-year growth in adjusted gross margins in the near term.
Second quarter adjusted EBITDA was $41.5 million representing an 18.6% margin, an increase of approximately 110 basis points year-over-year. Second quarter non-GAAP EPS was $0.52 per diluted share, a year-over-year increase of $0.18 per diluted share.
Turning now to cash flow. We generated operating cash flow of $21.9 million, a Q2 record driven in part by continued strength in DSO performance, which came in at 33 days. We have now delivered 28 consecutive quarters of positive LTM operating cash flow. Second quarter free cash flow of $13.4 million was also due to a record. We remain optimistic about our potential for continuing cash flow generation given our long-term model, our substantial NOLs and our low DSO.
Before turning to guidance, some comments on Aceyus. The acquisition is for $82 million in cash, subject to certain purchase price adjustments. We expect this transaction to close by the end of our third quarter. The ongoing acquired revenue and margin contribution will be immaterial to Five9, but as Mike described, Aceyus uniquely positions Five9 to streamline the migration of light enterprises and to leverage contextual data to deliver personalized experiences throughout the customer journey.
I'd now like to finish today's prepared remarks with a discussion of our guidance for the third quarter and full year 2023. For top line, we're guiding Q3 revenue to a midpoint of $224 million, which represents a 1% sequential increase in line with the typical guidance spend heading into Q3. For the full year, we are increasing the midpoint of our revenue guidance from $907.5 million to $909 million.
As I mentioned earlier, the consumer vertical in our installed base faced macro headwinds in the second quarter. Given that consumer is typically our most seasonal vehicle in the second half of the year, we are being prudent for now with our annual guidance by factoring in this uncertainty.
As for the bottom line, we are guiding Q3 non-GAAP EPS to come in at a midpoint of $0.43 per diluted share. For the full year, we are increasing the midpoint of our non-GAAP EPS guidance from $1.75 to $1.81 per diluted share, for the third quarter and the annual non-GAAP EPS guidance mirror the prudence in our revenue guidance. Please refer to the presentation posted in our Investor Relations website for additional estimates, including share count, taxes and capital expenditures.
In summary, we are pleased with our second quarter performance. While the current macro environment continues to temporarily challenge our installed base. we remain highly optimistic about our long-term growth prospects due to our significant momentum upmarket as demonstrated by the new large logo wins, our ability to continue capitalizing on the AI and automation opportunity and international expansion.
Operator, please go ahead.

Question and Answer Session

Operator

(Operator Instructions) Our first question will come from Scott Berg with Needham.

Scott Randolph Berg

Dan and Barry, congrats on the nice bookings quarter. I'll make it a multipart one, though, to get it all in. I guess the question is during the conference call here, you had a press release on your recent ranking within the new Gartner Magic Quadrant. I guess the kind of -- the two components in there is: a, what changed this time versus the prior rankings because I believe you were not in the leaders category previously, which you have been ranking to the leaders category now?
And then second, I'm going to kind of quote from it, it said "because a specific criteria based on your completeness of vision and ability to execute." I guess what do they find in there in particular that was appealing?

Michael Burkland

Yes. Scott, great question. Yes, we're very pleased to be back in the Leaders Quadrant. As you may recall, we were there in the past, and it's nice to be back and recognized by Gartner as a leader in CCaaS. And what changed, quite frankly, I think it's recognition and validation of all the success we're having really across our strategic initiatives, the march up market, right, those very large enterprises choosing Five9. Our win rates are significantly as high as they've ever been, and we're winning some of the biggest deals in the market. I think that's one.
Our international expansion is another and our AI leadership is the third. We talked about the strategic initiatives for a long time. And I think Gartner recognizes our progress in those. So we're thrilled, we're happy, we're honored, but we're also not surprised.

Operator

We will now hear from Ryan MacWilliams with Barclays.

Ryan Patrick MacWilliams

Great to see the large deal momentum in the quarter. So how does your large deal pipeline look like for the second half of the year? And are you seeing these generative AI tools put more priority on contact center leaders for moving their contact center systems from on-prem to the cloud at this point?

Daniel P. Burkland

Yes. I'll take that one on the pipeline. It looks very strong. As we've talked about earlier, that portion of the market is just opening up to CCaaS for the first time here in the last couple of years by kind of being a first mover and capturing some of those largest opportunities and then getting their validation that we're executing very well. It's got others turning and coming to us. We saw a record number of RFPs. We've seen a vast increase in the pipeline. It takes those companies quite some time to get through a sales and selection process and we've got a larger pipeline than ever, and we continue to scale the sales team and commensurate with that.
As far as AI driving more interest, it's a combination. Mike touched on it earlier in the prepared remarks. It's a combination of both the legacy systems being longer in the tooth and not getting the investment. And secondly, it's the only way you can really implement the AI effectively and do so at scale is to move to the cloud first. So most of them are recognizing they need to get there. And they're not already on -- well into a process, they're accelerating that process.

Operator

And we will now hear from DJ Hynes with Canaccord.

David E. Hynes

Congrats on the quarter. Dan, maybe one for you. I'd love to get any color on how that $42 million in enterprise bookings compares to maybe the past few quarters. I mean I don't think that's a metric you've shared with us in the past. And then the follow-up there would just be like anything you'd call out with respect to channel momentum? I mean is that being driven by international? Is it just the maturing of that go-to-market motion? Any color there would be helpful.

Daniel P. Burkland

Yes. Great, DJ. It's -- if you look at the large mega deals as we've referred to them, we have the parcel delivery service as well as the healthcare conglomerate, but never have we had a series of wins of this size. So when you look 3 or 4 deep or even 10 deep on that list, of largest deals for the quarter, we've never seen this many of this type of volume. So that's why Mike called out the fact that we're over $40 million there just along those 4. So it's not a super high concentration that may have been the case a couple of years ago. We're seeing this become more of a norm. So that's a great sign there.
As far as the channel, that's across the Board. We have a very strong partner group that manages and brings on new partners headed by Jake Butterbaugh, I mentioned him before. He's been with us for several years for, I think, 4, almost 5 years now. And we've really scaled up that part of the organization. And it's not just about going out and signing up new partners, but it's making sure that they view us as being their go-to-market first choice.
We spent a lot of effort and a huge investment to make sure that we're catering to our partners and making sure that they can go-to-market and represent Five9 in the right way, and that we always make sure we're doing the right thing for the customer, but we're also doing the right thing for the partner, making it easy to do business with us. And I think through some of the channel checks that are done by many of you, you get that same feedback. We want to continue to be in that pole position, if you will.

Operator

Meta Marshall with Morgan Stanley has the next question.

Meta A. Marshall

Great. I just wanted to know if you could either quantify or just kind of lay out cost savings on Aceyus and kind of streamlining those cloud transitions? And then just maybe on that, does it allow you to not have to kind of invest as much in professional services resources just to transition those customers eventually?

Michael Burkland

Yes, I'm happy to start on that, Meta. Again, the beauty of Aceyus is that they are so entrenched in the Fortune 100 large enterprise contact center market. And that's -- quite frankly, they got our attention in these joint accounts that we were winning with them. They are beloved by their large enterprise clients. In fact, we see RFPs fairly frequently where -- there's a requirement in the RFP is to integrate with Aceyus, and we've even heard just verbally anecdotally from a lot of our largest prospects that -- the one thing that we're going to require from our CCaaS provider is that they integrate with our Aceyus because that's how we run our business.
So that's, first and foremost, something that I want to make sure everybody understands. They are very, very strategic to us. They've got a fairly sizable installed base and large enterprise on-premise and their ability to have these data integrations across so many back-end systems is really what allows us to streamline this.
Remember, we talk about migrations from on-premise to cloud is very similar to a heart transplant, right? This is a major business transformation. And the fact that these large enterprises can continue to run their business during the migration with continuity of data that's how they run their contact centers. So as they're migrating off of legacy on-premise and onto Five9, that's really what we mean by streamlining. It's the ability to kind of have continuity across their business throughout that migration time period and beyond.
And then the second real leg of the stool is that contextual data that Aceyus brings to our platform and the ability to leverage that contextual data across all these data silos in the enterprise to deliver that personalized customer experience. So it's really two very, very significant value propositions and strategic reasons why we did the acquisition.

Operator

We are moving on to Peter Levine with Evercore.

Peter Marc Levine

Mike, you mentioned something in your prepared remarks, 80% of the $1 million plus deals in the quarter had AI. So I guess if you look across your installed base today, what's the attach rate look like? And perhaps what's holding customers back from going all in? Is it they're just not ready internally with the data? Is it the macro? Is it budget? Just kind of help us understand what's really stopping customers from going all in.
Squeeze in a second is just help us on pricing. I know there's a lot between how you charge other contact centers if it's on a per seat, per user basis. Or is it a consumption model? But just curious if you can share with us the conversations today that you're having with customers around pricing and AI?

Michael Burkland

Yes. Sure, Peter. I'll start with the pricing. Again, we have 8 products in our AI and automation portfolio. They range in terms of pricing as to most of our capacity-based pricing, in other words, per port, if you will, or oftentimes, it's -- we offer usage-based pricing as well. So we're pretty flexible across the spectrum of pricing options. At the end of the day, it's all ROI driven, right? And the efficiency gains and the productivity gains that our customers enjoy from our AI products is very significant. And that's really what drives that price point.
In terms of what's -- your question about holding back. I actually think that almost every enterprise that we talk to is very interested in AI and automation. There is definitely an education process that has to occur. Most large enterprises are also looking at how to implement AI across their enterprise in general, not just in their contact center, but how to avoid some of the pitfalls, if you will, that are out there in the press. So I think it's just an education process more than anything. But don't -- I think that 80% attach rate to our large enterprise deals is a very good data point in terms of the interest level in AI and automation across our prospect base.

Operator

Our next question will come from Samad Samana with Jefferies.

Samad Saleem Samana

Barry, just I wanted to ask about the guidance. I appreciate the clarity on the consumer vertical and the impact in the second quarter. I think you can see it in kind of the sequential uptick in subscription revenue in 2Q as well. I guess I just wanted to understand, one, had it not been for that because I think prior guidance implied more like a low 20s exit rate for subscription revenue as the year progressed.
One, I guess I'm trying to understand, is that the right way to think about it that now you're thinking more like a mid -- like high teens subscription revenue number exiting the year based on the current guidance? And just was it because of the consumer vertical? Or is there anything else factored in, did not rolling forward the full 2Q beat?

Barry Zwarenstein

Yes. Thanks, Samad. So let me sort of start at the back end over there and not putting through the full amount. That's right, we put through 17% of the total beat in Q2. This is really a function of this pocket of weakness that we had in consumer. And we need to be cautious when we go into the second half in these uncertain times. So we have data from our customers. We're highly network-driven. We also have macro there.
The consumer, if you go by federal data of consumer spending, it started with a roll in January at 12%, February went down to 8% and March to 4%. And then in the second quarter, it was 3%, 3%, 2% for the 3 months. If you look at the credit card spending on discretionary items, that too has been coming down quite dramatically. So we just want to be careful on over here.
Our retention rates stay very good. And when that part of our business has experienced a benefit of an eventual pickup in the macro, we will participate fully in it. So the second half -- to finish off in the second half is largely due to the fact that we dealt into the second half of the year with slightly lower than revenue in our consumer part.

Operator

And we will move on to Taylor McGinnis with UBS.

Taylor Anne McGinnis

Maybe just to piggyback off of Samad's question. So when you think about the second half of the year and then some of the seasonality that you're talking about in these different verticals, any color you can give on the contribution that Consumer has to the second half? And I know you've talked about some weakness in other verticals in prior quarters. So I guess any additional color you can give on what you're baking in for those verticals? And as a second part to the question, in terms of when we should start to see some of these newer enterprise deals maybe offsetting some of this macro weakness, I guess, what does the ramp look like from here on those as well?

Barry Zwarenstein

Okay. So in terms of the contribution to the -- from the Consumer, we're assuming something similar to what we had last year and then previously assumed. We just don't want to go out too far. So being a little bit cautious over there. There are other 16 verticals that we track in the second quarter. They grew very similar to what's happened in the second -- in the prior year with low single-digit growth in both last year and this year, and we're putting in similar growth in the second half of the year.
In terms of when we would see the kick in of these bigger deals, they often -- as I think somebody said earlier on, we've got now the volume of these deals. It's going to be a while before they kick in but you'll see the fact that we are reporting the numbers that we are is in part due to the fact that this weakness that we have in this last quarter on the Consumer side has been largely offset by the growth in the new logo, which is very strong.

Operator

And William Blair's Matt Stotler has the next question.

Matthew Alan Stotler

Maybe just a follow-up on Aceyus. Interesting to see that acquisition. Obviously, I think the strategic rationale that you laid out made sense. Would love to maybe just double click on how you're thinking about the opportunity there, whether that's ultimately expanding the TAM, right, and any associated incremental monetization you can do there? Or is this more so just helps to open up maybe the on-prem TAM especially at market that maybe it was harder to crack or both. We'd love to get some additional thoughts there.

Michael Burkland

Yes, Matt, I'll start with that. Again, think of this as -- I don't want to repeat what I already said. But I think one of the big opportunities here, big rationales besides what I already said is the pull-through value, right? So we would -- we always -- whenever we make an acquisition, there are obvious revenue synergies that we look at. But I think when you think about Aceyus, the #1 kind of revenue opportunity is really the pull-through. Our win rates in large enterprise are already very, very strong. But this just solidifies our competitive advantage upmarket by having Aceyus as part of the Five9 platform.
This is something that is very unique in the market, and it's going to be very difficult for competition of ours to have a similar offering. So that's going to allow for pull-through continued wins upmarket and large enterprise for us. That's a big lever.

Going back to Peter's question on the 80% attach rate for the $1 million-plus deals. Any sense as to what that was last quarter or last year at this point? And what is differentiating Five9's AI versus the other CCaaS vendors in your view? And then, Dan, just quickly for you, on that big healthcare win, nice to see. Is this going to act like that large parcel delivery company and we'll see further regional expansions given their 50,000 seats in aggregate? Or how are you viewing the potential expansion from here?

Daniel P. Burkland

Great questions. First of all, the 80% attach rate, I don't have the measurements from the previous quarters exactly. But I can tell you, that's a very common trend in what we're seeing and it's only been increasing. I mean as AI and automation becomes that much more important, it's asked for in virtually all the RFPs today is presented whether asked for or not. And we can find use cases for customers across the board now that we have this full portfolio of 8 different applications that we can deliver and combinations where you combine the two and deliver a pretty unique use case.
So we're seeing that in a lot of brainstorming within the new customers. They use it to justify their business case to move to Five9 and to the cloud, in particular, but also in the installed base. We can see tremendous ROIs. And so we see a better attach rate there, as Mike alluded to earlier.
Moving over to the second part of your question, no, I don't recall what it was.

James Edward Fish

So is this going to act like...

Daniel P. Burkland

I got you. Yes, the account we mentioned. It very well could. Bear in mind, these transitions take time as they come on to the platform. They will continue to expand their use of various applications that we did not sell them initially. We have certain things that were preexisting that we're integrated to. In that case, as an example, Aceyus was already -- they were already a customer of Aceyus. We're doing that integration, directly with that as a strategic element.
They already have Verint throughout their many, many different sites that's on-prem. We're going to integrate to that via our voice stream AVI. Eventually, they'll look to probably upgrade the Verint solution to our cloud and the Verint cloud that we integrate with. So we'll be providing many add-ons just like most of our large enterprise customers. The CAGR of the adds and the expansion that they experienced with us is tremendous. So when you look at our dollar-based retention rate and you look, the further upmarket you go, the higher that percentage is just because they tend to buy everything on the truck, so to speak.

Our next question will come from Michael Turrin with Wells Fargo.

Michael James Turrin

I think look, a lot of the questions have been on the initial reaction around the beat and the raise. But if I look at the filings, Barry, the RPO metric is up 45% year-on-year. I think it's up double digits again sequentially. So maybe you can just tell us more around your view of the significance of that RPO metric. Is that becoming more valuable as you move up market and maybe reflective of some of the momentum that you're highlighting? And maybe you can just help level set considerations we should be making around conversion of bookings to subscription revenue over time as well.

Barry Zwarenstein

Yes. Thanks, Michael. So indeed, 13% sequential growth, 46% year-over-year growth, $1 billion in total. The situation there though, Michael, is that, that only captures part of the picture and a volatile part of the picture. Why? Because it includes only contracts that have more than a year to run. And that's not all of our business. Now we've always said that the only thing you can really use the RPO concretely for is to see directionally which way it is heading. And the work that Dan and the team have done and the market that they're going into, makes it really clear that the direction on the new business is up and to the right.

Michael James Turrin

Is there anything you can say around just the composition of top types of customers that are showing up in RPO versus what's the case? So I just want to get a sense of multiyear today versus what that used to look like historically.

Barry Zwarenstein

Yes. It is so much across the board. I mean the contact center industry is a horizontal industry. There is some concentration in our business in terms of healthcare, financial services, consumer, but then a whole smorgasbord of other industries below that. Frankly, I don't have a detailed analysis of that, that I can share, in part because it is not a key management metric for us.

Daniel P. Burkland

If I may add one thing to that, Michael. Bear in mind, we don't incent our customers or provide additional discounting for longer contract cycles because we're so confident in the renewal rates. Our contracts automatically renew each year, every year. So oftentimes, we look and say, well, how long is the term of this customer, and we don't know. Because we're just -- we put the contract in the drawer, it never gets opened again.
It's an auto renewal. So it's the beauty and it's also one reason why we have a lot of annual 1-year contracts but we have a fair amount of 3-year and 5-year as well. Mostly, it's because the customer wants to protect themselves against price increases when they do multiyear.

Moving on to Matt VanVliet with BTIG.

Matthew David VanVliet

So I wanted to dig in maybe a little more on the attach rate and contribution on the AI side. So you mentioned 80% of the larger deals. But can you give us any sense for how much of the ARR of those deals is actually sort of tied to these AI features, presume it's up year-over-year, but maybe more importantly, where do you think that goes in the next 3 to 5 years? Can it be 20% or 30%? What's sort of the upper bound of what people are going to pay for?

Daniel P. Burkland

Yes. I'm glad you brought that up, and I'll start it and Mike, you can continue. If you look at the attach rate, yes, 80%, a big number. If you look at the revenue contribution, small number, a very small number. And the reason being is we're at the very beginnings of really implementing AI and automation in the right use cases. Today, you have a very simplistic straightforward question that gets asked repeatedly within the contact center. Well, if you automate that, you can let the customer self-serve for it, and that's great.
So a lot of customers are looking at deflecting 3% to 5% of their calls over. And if you think about the pricing that we've dictated well to you, so if you put in 6% to 10% of the revenue contribution from that customer because they're deflecting that many calls over, yes, we make more on those automated calls than we do nonautomated calls. But it's still a small percentage. So in 3 to 5 years, boy, I'm optimistic that, yes, the crystal ball says more and more use cases will become prevalent.
Consumers will get more used to and comfortable talking to a machine versus a human. But for the consultations and the sales calls and all the other things that you need to really speak human-to-human, that's where we implement automation to help that human-to-human conversation. And we assist at making it more powerful and more efficient in delivering data to that agent more quickly and more accurately.
So there's automation we can apply to help a contact center be more efficient and effective. But across the board, where I'm going here, is it's really hard. We have some customers to go all in and put multiple applications in, and it's a much higher percentage and others where they're just barely scratching the surface. The beauty here is, over time, we know it's going to increase. We know it's going to be more prevalent. We know some is going to be based, as Mike said earlier, on a per port or capacity-based.
We're going to have others that are transactional or per minute or on a usage basis. And in all those scenarios, it's Five9 software being delivered to help enterprises deliver a great customer experience. And so our revenue per customer, without a doubt, will continue to increase and do so handsomely.

Siti Panigrahi with Mizuho has the next question.

Sitikantha Panigrahi

I want to ask about the margin. Look, you guys have like 100-plus -- 100 bps-plus margin -- gross margin expense and also operating margin. Should you expect this trend to continue? Or how should we think about your investment, especially with this AI opportunity? And also, could you talk about the Aceyus, how is that going to impact your margin?

Barry Zwarenstein

So let's break it into the 2 components: growth and operating expenses. In terms of gross margin, if you look at over the longer term, it is very clear that, that's going to go up. Why do I say that? It's simple. There are a number of factors, but the biggest single one is the leverage between fixed and semi-fixed costs. And sometimes to understand what's going to happen in the future, you need to look at what's happened in the past.
And if you look at the past 10 years, nine out of those 10 years, the gross margin on our subscription business expanded. The only exception was we're going to do some heavy investments in the cloud and in international. And the rough numbers, software already accounts for approximately 75% of the total revenue. So it's a growing proportion. And when we're in public, it was certainly less than 60%. So we have that tailwind.
Currently, we're in the low 70s, but on our way to the 80s. Like we've demonstrated, we can improve over time. The near term, though, on security margins and gross margins is very revenue-dependent, as I just alluded to. And we are making some additional investments, particularly while Dan is bringing in these mega deals that require some incremental investment until we really get scale fully.
In terms of the EBITDA margin, we're very serene over there. We've got a long-term model and we take all 3 components. We have 47%, this is up to about 2027. We're currently at 43%. So we can actually still go up and still make our 23% EBITDA margin that we're anticipating.

Moving on to Will Power with Baird.

William Verity Power

Okay. Great. I think probably for Dan, great to see the multitude of new big wins, maybe just zeroing in on the Fortune 50 healthcare win, it would be great just to understand kind of what that process looks like, who you replaced, I'm sure you competed with your competitors. What really kind of helped you to stand apart there? And this seems to be part of a string of healthcare wins. Maybe to cover more broadly what's going on with healthcare for you? I mean reference accounts probably helped. And I guess the extension of that is how do you replicate that in these other verticals?

Daniel P. Burkland

Yes. No, great question, Will, I appreciate it. And if you look at the upmarket expansion and the penetration we're making across many verticals, some that are very prevalent with large contact centers are certainly healthcare and financial services, large consumer product companies. I mean think about who we, all as consumers, contact every day, right? Healthcare is one that's not going away ever, especially as our population grows older.
So if you look at that, the insurance company that we sold across the board has several legacy systems. It wasn't one particular one, but it's the typical 3 that we've talked about in the past. And that's the issue, right? They've grown. The healthcare companies and insurance companies have all done M&A activity over the years and you get these systems that are a decade or 2 old. And they don't do a whole lot. And what they do, they do it for that given building, right?
They're premise-based systems that operate for that one set of resources or users that are in that facility. And that creates silos of efficiency, small ones and that creates great efficiency when you think about what a virtual contact center can do like Five9. Because just the sheer moving of calls from the cloud straight to the resources as if they're under one roof is a tremendous saver that we've had for years.
Well, they now can take advantage of that. They also can take advantage of all the AI and automation that we deliver from the cloud. So it's a great vertical for us. It's one that's leaning into to CCaaS right now, primarily because of those AI and automation solutions and the old legacy platforms they're on. But also it's one that they're leaning into because they are going through a rapid change themselves in M&A activity and want to be -- want to have the flexibility to do so in the future.

Operator

Our next question will come from Deutsche Bank's Matthew Niknam.

Matthew Niknam

So obviously, new logos, you talked about a very strong quarter. Can you talk a little bit about where you're taking share from, how it's evolved in the last few quarters, and then just any color you can provide on linearity of bookings during 2Q?

Daniel P. Burkland

Yes, taking share. It's still primarily moving off of the legacy Avaya, Cisco, Genesys. Genesys has a massive -- they're also a cloud competitor. But they have a massive installed base, some estimate over 2 million seats out there that they've indicated are being end of life and need to be replaced. They're going to get a big share of that. They've already demonstrated that in some of the figures that they've already disclosed. But we're going to get some, too.
It gets an opportunity for most to go shopping and really put on RFPs and see what's in the market. And we love that opportunity and we get a great share in those opportunities. So it's those 3. And then on occasion, we do find that they're CCaaS providers that have either gone through a partner that wasn't really astute and up to speed on being able to really maximize the value for that company to extract the value for that product. And sometimes it's just the wrong fit for the enterprise. And so they do make a change.
So we do have CCaaS providers that we replace. And one example I gave was -- in the prepared remarks was a company that had already embarked on a competitor implementation of ours. And the company that they acquired had made a recent decision prior to that to go with Five9, but hadn't started an implementation. So they basically contacted us to cancel that contract. And we asked them to take a closer look and give us a chance and evaluate the two side by side, even though they were several months into another implementation. And they ultimately made the decision that we were the better fit for them, and they went our way.

Matthew Niknam

And just on linearity, any color there over the course of the quarter?

Daniel P. Burkland

On the course of the quarter, linearity in our business, I'd love to achieve it. I've, for a few decades now, strive for that. The deals at the lower end of the market, we can get more linearity and more predictability because we see the lead flow and the sales cycle, and we know our close rates are very consistent. On the high end of the market, it's really tough. It's lumpy because we have these big deals that make a huge swing.
We had quarters where even talking about the top 3 or 4, we've had quarters where that number is far lower than in other quarters, where we've dwarfed it with some big numbers like this one. And so it's hard to get linearity until we get the higher volume, but that's something we're certainly striving for.

Operator

And we do have time for one additional question, which will come from Catharine Trebnick with Rosenblatt.

Catharine Anne Trebnick

Dan, could you piece part a little bit, you did, WWT, BT and Telus is all new partners in the last couple of months. How long does it actually take to put the go-to-market strategy and generate revenue from these big partners?

Daniel P. Burkland

Yes. Wonderful question, Catharine, and that's something, and I'm glad you mentioned it because it is something we want to make sure folks realize that it's not a sign them up and open the floodgates. It's you've got to train them, educate them, have them make the investments in their go-to-market and some of the back-office support that they're going to provide to the customers.
In many cases, these large service providers, like the ones you mentioned, they're doing this not just to bring product to their customers but to really get services around them. we have something we've referred to as project pull-through, which is enabling these varied types of partners to be able to enable the implementation services, professional services, if you will, as well as ongoing support for at least Tier 1 and Tier 2.
That gives us, in the long run, better margins and it gives them an ability to make money off of the services that they're used to delivering on their legacy solutions. And it gives them an incentive to want to bring us into their opportunities because they recognize, aha, I'm going to get the services business for this. It's not just the margin on the markup. So how long does it take? It varies. But usually, it's at least 6 to 9 months before we really start to see a pipeline build up and probably 1 year to 1.5 years before we see some revenue contribution. Because again, there's a sales cycle there and most of these are going after customers that are on the larger end of the scale.

Catharine Anne Trebnick

Congratulations on the acquisitions.

And again, everyone, that does conclude today's Q&A. So I'll turn things back to Mike for closing comments. Mike, over to you.

Michael Burkland

Yes. Thank you for joining us, everyone. As we cross the midyear mark and just I couldn't be more thrilled with what I've seen in terms of momentum in our business. We talked a little bit about it in terms of upmarket momentum, the deals that Dan talked about. It's an exciting time for Five9, exciting time in our industry, and we look forward to continuing the conversation with you all. Thanks for joining us.
