Thanks, Emily, and thanks, everyone, for joining our call this afternoon. We are pleased with our first quarter results, which exceeded our guidance across all key metrics. Subscription revenue, which now makes up 80% of total revenue, grew 14% year-over-year. This was primarily driven by LTM enterprise subscription revenue growing 20% year-over-year. Adjusted EBITDA margin was 19% for the first quarter, helping drive a Q1 record operating cash flow of $48 million or 17% of revenue and an all-time record of free cash flow of $35 million or 12% of revenue.
Today, I'd like to start off by providing key highlights of an extensive operational review we recently conducted across the company. We believe the transformation initiatives we are executing will help bolster our long-term competitive position and reestablish ourselves as a rule of 40 coming as we continue to drive profitable growth. As we pursue this evolution, our goal is to deliver increased profitability while prioritizing investment in key strategic areas, including AI and go-to-market initiatives to drive revenue growth and capitalize on our massive TAM that we believe is significantly expanding with AI.
The transformation will take time, but we're moving quickly and driving cross-functional alignment across the entire organization to achieve our goals. As a result, in 2027, we are targeting to be above the rule of 40 on an adjusted EBITDA basis and be approaching the rule of 40 on a free cash flow basis. Bryan will provide more details on this in a moment.
Now I'd like to dive deeper into our AI-powered platform and how it's well positioned to empower brands to elevate their CX and how they're realizing meaningful benefits through our Genius AI suite of products. As I touched on last quarter, in order to deliver personalized and accurate self-service using Gen AI, you need four key ingredients. First, you need access to LLM and it's critical to enable brands to easily change the underlying engine to leverage the latest high-performing models. We believe our engine agnostic approach allows brands to future-proof their AI decision and our AI application layer above these engines acts as the key competitive advantage.
Second, you need contextual data, which includes consumer-specific and brand-specific information that is distributed across a large number of back-end systems. Our platform typically integrates into 20-plus systems which enables contextual data to be fed into the LLM in real time in order to provide true context around an interaction.
Third, you need historical interaction data. Our CCaaS platform is the system of record for interactions between a consumer and a brand across all channels, including those handled by AI agents as well as human agents.
And fourth, you need a platform that provides all channels such as voice, text, e-mail, web chat and social to connect consumers to an AI agent as well as to provide a seamless escalation path to human agents. The market demands AI agents that work across all of these channels, but providing a voice channel globally at scale is a huge barrier to entry.
These are key reasons why AI point solutions and third-party AI vendors are strongly leaning in to partner with us and integrate to our platform. As a result, our platform acts as a control point where we are successfully monetizing that access through our voice stream and transcript stream APIs.
To further enhance the value of our platform, we announced that Five9 is deepening our Salesforce partnership to launch of Five9 Fusion a best-in-class native integration with Salesforce to deliver better AI-powered customer experiences.
With Five9 Fusion, we combined Five9's real-time system of interaction together with Salesforce system of customer record to create a fully integrated AI elevated solution for customer experience. With these new product bundles, which are available today, this enhanced integration helps businesses deliver better customer experience, hyper-personalized self-service, and achieve smarter results with a future-ready foundation to drive meaningful business outcomes for our joint customers.
Also, we continue to see significant AI momentum driven by real ROI that we are delivering for our customers through our Genius AI suite of products. This, in turn, drives our subscription revenue growth as demonstrated by the following three customer examples. The first is a fast food chain with over 3,000 restaurants globally. Following the deployment of our AI agents, they experienced a nearly 40% improvement in containment rate. Concurrently, the implemented our agent assist solution, which reduced after-call work time by 35%.
As a result of these efficiency gains, they estimate their labor savings to be approximately $1.1 million per year. And since deploying our AI agents, their ARR with Five9 increased by 37%. The second example is a global payment processing provider in the UK. They deployed our AI agents and experienced a 10% increase in self-service in the first year as well as a 50% containment rate. They also recently deployed our AI Insights product in the first quarter of this year to identify even more use cases to generate additional ROI with our suite of AI products.
Since deploying our AI agents, their ARR with Five9 increased by 49%. The third example is a personalized health care company that provides patients with easy access to medical equipment and supplies covered by insurance.
Following the deployment of our AI agents, they have driven a 15% reduction in call volume by automating common questions such as medical equipment delivery status and insurance guidelines. They also expanded the use of our AI solutions biting chat bots and agent assist to gain further efficiencies. Since deploying our AI agents, their ARR with Five9 has more than doubled.
Additionally, we continue to lead the CX market with key AI innovations as demonstrated by our recent announcement of a new offering called Spotlight for AI insights which is designed to help brands unlock the voice of their customers, hidden troves of interaction data.
AI Insights leverages Gen AI to mine customer conversations at scale and understand emerging topics, top trends and root causes of issues through a powerful visualization interface. Spotlight takes AI insights to a whole new level by harnessing the power of Gen AI to discover specific trends and metrics that are typically very difficult to identify in an automated fashion.
We believe this will not only provide key insights for contact center operators but also empower lines of business leaders with valuable data and tailored intelligence to continuously improve their business through increased sales enhanced products, elevated CX and more.
Another AI capability that is becoming a key part of driving AI agent adoption is our dial of trust. This allows brands to scale the level of Gen AI that is incorporated into our AI-enabled solutions. Gen AI is becoming more powerful and more accurate by the day. However, there is a trust spectrum for brands that will vary by different topics and different industries when using AI to confidently provide customers with accurate information and answers.
Our dial of trust enables brands to manage this risk through a continuum where the level of Gen AI infusion can be modified for various use cases. We believe that this tooling is essential for delivering trusted AI.
As a result of our leading position in AI, we continue to see significant momentum in our AI business as evidenced by virtually all of our $1 million-plus ARR new logos continuing to attach AI and AI making up more than 20% of enterprise new logo ACV bookings.
Additionally, our enterprise AI revenue grew 32% year-over-year in the first quarter, making up 9% of enterprise subscription revenue. We also continue to further penetrate our installed base by leveraging our revolutionary AI Blueprint program. It's still early days, but preliminary results are very promising.
For instance, in the last several months, we have been collaborating with a growing number of our customers to help them build their AI road map and identify use cases to generate significant ROI with our AI solutions. 50% of customers going through the AI Blueprint process have purchased our AI products.
We're highly encouraged by these results, and we expect this momentum to accelerate throughout the year. In addition to our AI momentum and opportunity, there remains a significant opportunity in our core CCaaS market, with a $24 billion TAM as cloud migrations continue.
Therefore, we remain very optimistic about our long-term durable global opportunity, especially at the upper end of the market, which is the largest and least penetrated part of the market and the fastest-growing category of our business.
Now I'd like to touch on the momentum we're seeing with some of our key partners. As we announced in November, Five9 and ServiceNow continue to execute on the goals of our strategic partnership. Later this quarter, Five9 transcript stream will integrate into ServiceNow interaction management, enabling agents to focus entirely on customer issues without the need for manual note taking.
ServiceNow now assist powered by Gen AI will leverage these real-time transcriptions to generate summaries and resolution notes significantly reducing call wrap-up activities and average handle times. Additionally, Five9's intelligent routing engine will soon route service out digital channels and cases, ensuring seamless and efficient case management. ServiceNow is also integrating its [Mata data] to enrich Five9's workforce engagement management solutions.
This will reduce operational overhead for managers by streamlining routing management across both platforms. Making it easier to adjust staffing dynamically during peak demand periods.
Additionally, last quarter, we announced our launch on the Google Cloud marketplace, both in the US and internationally and we saw more than $35 million in ACV pipeline added in the last two months. We're very pleased with the early traction and anticipate the strong momentum to continue. We also recently teamed with IBM to integrate [Watson X] into our Genius AI platform to bring customers the option to leverage [Watson X] as their preferred LLM when building AI-powered CX solutions.
This collaboration is designed to enhance our platform's flexibility and help drive the next wave of innovation in AI-powered CX, enabling businesses to deliver more personalized, efficient and impactful customer experiences.
In summary, we are pleased with our continued momentum in AI for CX and our execution against the massive core CCaaS market opportunity. We believe that our differentiated approach to accelerate AI adoption as well as ongoing innovation of new AI offerings to support the entire customer journey from self-service AI agents to agent augmentation to operational efficiency are key drivers fueling the momentum in this fastest-growing category of our business.
Additionally, I want to thank our team of Five9er's, whose passion and unwavering dedication continue to be the driving force behind transforming our business to strengthen our leadership position in the industry. We are off to a strong start in 2025, and I look forward to sharing our progress as the year unfolds.
And with that, I'll turn it over to our President, Andy Dignan, Andy, please go ahead.

Andy Dignan

Thank you, Mike, and good afternoon, everyone. In the first quarter, we continued to execute well against a strong pipeline, seeing an increased volume of new logo wins year-over-year despite some lengthening of sales cycles on larger deals, which we attribute to the macro backdrop. From a geopolitical perspective, we are starting to see some resistance in international regions to doing business with US vendors, but we are monitoring this very closely as we are operating in a very dynamic environment.
For our installed base bookings, we had the highest year-over-year growth rate for any quarter in the last three years. This is a direct reflection of the investments we've made to drive upsell and cross-sell motions into our customer base. And now as we normally do, I will share some key examples of wins.
The first example is a new business unit of our Fortune 50 financial services customer. They show Five9 to replace legacy systems and enable scalable, compliant voice solutions integrated seamlessly with Salesforce.
The solution will improve customer outreach through click to call and sharing TCPA compliant call recording and reducing call abandonment by running branch calls to the right banking professionals. The solution aligns with their digital transformation goals enhances the customer and banker experience and positions Five9 as a trusted partner in secure enterprise scale voice modernization. We closed this deal in early April and anticipate this initial order to result in over $2.8 million in ARR to Five9.
The second example is a leading vehicle mobility solutions provider that helps consumers with vehicle repair, replacement, fleet management, insurance and build services. They were using an on-prem solution that was difficult to manage and did not provide holistic visibility into all of their operations. As a result, as Five9 for our deep integrations into their ecosystem of applications, including Microsoft Dynamics and teams, they were also looking to maintain continuity with our partner, Verint, to avoid the retraining that would have been required on other platforms.
Most importantly, they selected Five9 for our extensive portfolio of Agentic AI solutions and the significant ROI they expect to generate by eliminating simple tasks with our AI agents and gain further efficiencies with our agent assist transcription and summary capabilities. We anticipate this initial order to result in over $1.7 million in ARR to Five9.
The third example is a nonprofit health plan serving roughly 400,000 members in California. They were using an on-prem system that lacked key technology capabilities. They choose Five9 to modernize their customer experience by leveraging our comprehensive suite of AI solutions, including AI agents for self-service, agent assist for transcriptions and AI insights to identify new AI use cases and efficiency opportunities.
They are also looking to enhance customer experience across text, chat, e-mail and voice channels, integrating seamlessly with their [Geva patient record system] and HSP claims solution for efficient call handling.
They also selected Five9 for our deep integration with Microsoft Teams, our WEM portfolio to optimize their operations and their analytics capabilities to fulfill their state compliant obligations. We anticipate this initial order to result in approximately $900,000 at ARR to Five9. And now I'd like to share an example of an existing customer who expanded their business with us.
This leading service provider of Medicaid and other government-funded self-directed care programs have been a Five9 customer for over 10 years. This customer partnered with us to win a major state contract resulting in a significant increase in the size of their contact center. Self-service is a major initiative with this expansion, which is why this customer selected our AI agents. With this add-on order, we anticipate the ARR to Five9 will increase from $1.5 million to over $5.5 million.
Bryan?

Bryan Lee

Thank you, Andy. We're pleased to report Q1 revenue growth of 13% year-over-year, primarily driven by subscription revenue growing 14% year-over-year. Subscription revenue growth was driven by: first, strong revenue contributions from our backlog of new logos, which exceeded expectations; second, highest year-over-year growth rate in three years for installed base bookings, which tend to turn to revenue quickly. And third, 32% year-over-year growth in enterprise AI revenue, which continues to be the fastest-growing category of our product portfolio.
However, as anticipated, we experienced tough year-over-year comparisons due to a stronger downtick among seasonal customers in our consumer and health care verticals and significant revenue contributions from our largest customer, completing its ramp throughout last year.
In the first quarter, subscription revenue made up 80% of revenue, while usage revenue accounted for 13% and professional services made up the remaining 7%. Enterprise revenue from subscription, usage and PS combined made up 90% of LTM revenue.
Our commercial business, which represents the remaining 10% decline in the single digits on an LTM basis. Like many software companies, our commercial business is more exposed to the macro environment. Also, as a reminder, this trend is partially by design, driven by our ongoing focus on larger customers. Additionally, as expected, our LTM dollar-based retention rate came in at 107% versus 108% last quarter, primarily driven by the two tough comparison factors IP previously mentioned.
Turning now to profitability. We continue to generate strong year-over-year margin expansions across the board, primarily due to our ongoing focus on disciplined expense management. As a result, Q1 adjusted gross margin increased approximately 160 basis points year-over-year to 62.4%, and adjusted EBITDA margin increased approximately 360 basis points year-over-year to 18.8%, which is a Q1 record.
First quarter non-GAAP EPS was $0.62 per diluted share, up $0.14 or 29% year-over-year. Also, stock-based compensation decreased 12% year-over-year from $45 million to $39 million, which equated to 14% of revenue in the first quarter and we remain highly focused on continuing to moderate stock-based compensation over time.
Now I'd like to share some cash flow highlights. As Mike mentioned, I'm pleased to report that operating cash flow was a Q1 record of $48.4 million or 17.3% of revenue. This was primarily driven by our strong adjusted EBITDA and continued strength in DSO performance, which came in at 33 days.
Also, free cash flow reached an all-time high at $34.9 million or 12.5% of revenue, achieving a free cash flow conversion rate of 66%.
As a reminder, we're planning to retire the remaining $434 million principal balance of our 2025 convertible notes in cash when it matures in June. The next maturity of our convertible notes is 2029 so we feel comfortable with our cash position. In addition, we expect our free cash flow generation to improve meaningfully, putting us on a path to being net cash positive.
Additionally, we've developed a holistic framework to evaluate our capital allocation alternatives. Therefore, going forward, we will have a balanced approach in assessing organic investments versus share repurchases versus opportunistic acquisitions.
Before turning to guidance, I would like to provide more details on the financial impact of our transformation initiatives as well as share our perspectives on the latest (technical difficulty) condition and its impact on our outlook.
As part of our extensive operational review, we announced a 4% reduction in our global workforce on April 3. This impacted most of our departments mainly in the US and it represented a net reduction of $20 million to $25 million in annualized compensation related non-GAAP expense.
As Mike mentioned, our goal is to increase long-term profitable growth and surgically invest in key areas such as AI and go-to-market initiatives in order to capitalize on our massive TAM opportunity that is further expanding with AI.
In combination with ongoing cost optimizations, we expect the net effect to drive at least a 2 percentage-point improvement in annual adjusted EBITDA margin in 2025 from the 18.8% we reported in 2024. As a reminder, we expect one-time cash expenditures associated with the RIF to range between $7 million to $9 million and noncash expenditures of approximately $1 million to $1.5 million both of which are not accounted for in the non-GAAP bottom line guidance I'll be providing shortly.
With regard to the macro environment, I'd like to remind you that we started 2025 with what we believe to be conservative guidance based on the assumption that macro conditions would not change materially from what we were seeing at the beginning of the year. Given the recent heightened macro uncertainty, we believe it is important to take a slightly more prudent stance in terms of our guidance. As a result, we are keeping our full year 2025 revenue guidance unchanged at $1.14 billion. And for second quarter revenue, we are guiding to a midpoint of $275 million.
As for the second half of the year, we expect revenue to increase sequentially in the third quarter and slightly more in the fourth quarter. With regards to the bottom line, we are raising the midpoint of our 2025 non-GAAP EPS to $2.76, which is $0.16 higher than the guidance we provided during our last earnings call.
For the second quarter, this is the first time we're guiding Q2 to a positive sequential growth for non-GAAP EPS at a midpoint of $0.65 per diluted share. This is reflective of the net savings from our recent RIP as well as disciplined ongoing expense management.
As for the second half of the year, we expect non-GAAP EPS to increase sequentially in the third quarter and -- (technical difficulty). Please refer to the presentation posted on our Investor Relations website for additional estimates, including share count, taxes and capital expenditures as well as GAAP to non-GAAP reconciliations.
In summary, we're pleased with our first quarter results. We will remain laser-focused on everything we can control in order to drive strong profitability while making strategic high-impact investments in key initiatives to further our leadership position.
Operator, please go ahead.

Question and Answer Session

Operator

(Operator Instructions) Scott Berg, Needham.

This is [Rob Rally] for Scott. Congrats on the quarter. I would like to just touch on the subscription revenue guide for the year. Do you believe 1Q is going to be the trough for the year. I just like to see how that's going to trend?

Bryan Lee

Yes. So I can help answer that. So we haven't given specifics around the subscription growth in terms of guidance. You have our annual total revenue guidance out there. We have an unchanged of $1.14 billion from what we guided to at the beginning of the year.
And what's reflected in there is that -- if you kind of go back starting from Q1 throughout the year. In Q1, we saw relatively stable macro conditions, although we did see consumer and health care seasonal downtick being stronger, which was anticipated because of the strong uptick we saw in Q4. And then going into Q2, we saw the uncertainty in macro conditions increase a bit. So we are being slightly more prudent despite the fact that we're not actually seeing material changes in our business through April so far.
So with the slight prudence built into Q2 and the rest of the year, that's what's reflected in total revenue and a similar type of assumption can be made for subscription.

Scott Berg

And then when it comes to the Rule of 40 -- (technical difficulty) target you guys outlined, can you provide any color on the breakdown that you're anticipating, which means either adjusted EBITDA or revenue growth or free cash flow and revenue growth.

Bryan Lee

Yes. So the medium term, what we have assumed for revenue growth is 10% to 15%, and that's assuming a stable macro conditions similar to what we saw in Q1. Now from a bottom line perspective, we expect EBITDA margin in the 25% to 30% range. And if you kind of look at the different components there, the gross margin today, we reported 62.4% and we're expecting 66% to 68% in the medium-term model.
And that's really driven by our subscription gross margin getting deep into the 70s driven by revenue scaling against fixed and semi-fixed costs. And also, we have mix shifts happening for our usage and professional services revenue into subscription. And those have lower gross margins in 50s and breakeven levels. So that's a mix shift that helps overall gross margin. And of course, we'll expect to continue to get operating expense leverage as well.
And that's coming from the RIP that we just recently did. And the transformation initiatives that Mike talked about, where we'll be focused on various areas like automation, process improvement percentage of our workforce, increasing in lower-cost offshore locations and so on and so forth. So we're confident that we'll get to target above Rule of 40 on an EBITDA basis and approach all of 40 on a free cash flow basis.

Operator

Siti Panigrahi, Mizuho.

Siti Panigrahi

I want to relate to the comment about longer sales cycle on the enterprise side, you talked about DT macro. Could you elaborate a bit on that? Is it particularly in the international region or US, when do you start seeing that? And is this only on the enterprise side or mid-market? Any color would be helpful.

Michael Burkland

Yes. Good question. So yes, it's really focused on the large end of the enterprise market, just the bigger deals, just a little bit longer sales cycles. The team is still focused on them, obviously, continuing to go forward, but it's really just in that space. International, different reason, right, a little bit what's going on in sort of the geopolitical landscape, some (technical difficulty) business with US vendors. But we are focused on our installed base customers there, which as you heard had a good quarter.

Siti Panigrahi

Just to try if I did it trigger any kind of deal slippage to next quarter or anything? Or is that ongoing trend you saw?

Michael Burkland

Yes. So these deals just slipped into the next quarter, and the teams are still focused on those deals and things are looking good.

Operator

Raimo Lenschow, Barclays. .

Raimo Lenschow

Good to see you guys again. The quick question from me. Mike, you and I go way back, and we've seen uncertain times before, like how does Genius AI now play into kind of this environment and customers making a decision because it does feel like delaying it or kind of showing a lot of uncertainty might have been the old good reaction. But with AI now, it feels like we kind of actually need to move faster. Can you speak to what you're seeing in the field there?

Michael Burkland

Yes. Well, it's great to see you, Raimo, and thanks for being back on the team, so to speak. Yes, you're right. I mean, look, uncertain times always impact decision-making of any kind, right? But I think we're also benefiting from this AI revolution that is really causing a rush in a lot of ways by a lot of these companies to figure out every CIO is being told by every CEO, go figure out AI.
The good news is we've come up the learning curve as an industry, not the vendors necessarily because we've been at this for quite a long time, but I think the customers are coming up that learning curve.
And we're seeing great momentum in terms of decision-making. And it's not just in the 100% attach rate on new logo million dollar-plus deals that we're doing. It's also in our installed base. I mean, we have this AI Blueprint program, which we've been talking about and we came out with that a couple of quarters ago, and it's really, really working well, 50%, 5-0, 50% of the customers that go through this AI Blueprint program with us are purchasing our AI solutions.
And so we're penetrating our installed base, excuse me, as well as attaching AI to new deals. It is -- I feel like we've unlocked the opportunity with AI. But at the same time, look, this -- the real scale of AI use does depend on the ROI that we're delivering. And you heard about those three, just three of many customer examples where we're delivering real tangible ROI, whether it's higher containment self-service or whether it's reduction in after call handling time, it's an exciting -- (technical difficulty).

Raimo Lenschow

Okay. And then -- sorry. And then Bryan, one for you. Like if you think about the transformation you started following the review, if you think about it, how should we think about the impact on the organization in terms of the different divisions? Was that kind of and more like take underperformance out, think about more what is needed in the new AI world versus where we have people kind of working before.
Like how should we think about like the impact areas there, like -- is there going to be like a period where everyone adjusts or how should -- how is that going to play out for you.

Bryan Lee

Yes. So I can touch on it, and Mike, you can chime in. So it was across -- first of all, the reduction in force was across most departments and a majority of that was in the US. But what we made sure is that from a sales capacity basis, it's not impacted and we continue to reinvest in that area and our go-to-market initiatives as well as our AI initiatives as well. So that's where we're focused, and we'll continue to make sure that that's aligned internally strategically.

Operator

Terrell Tillman, Truist.

Robert Dee

Great. Mike, Andy, this is Robert Dee on for Terry. I wanted to double-click on the Five9 Fusion announcement with Salesforce, specifically, the press release mentioned that Five9 bring your own telephony adoption has doubled in 2025. What do you think is driving the growth in BYOT? And why now?

Michael Burkland

Yes. I mean, I think as we -- we've long been partnered with Salesforce, obviously, Salesforce has been heavily investing and taking their customers on the AI journey and we've been on that journey with them collectively. And so they've been really driving the BYOT within their customer base within their sales teams.
And so really the idea behind Five9 Fusion was to really simplify the go-to-market so that the sales force sellers, our sellers and then most importantly, the customers, they really understand the value proposition and what solutions you need on both sides. And certainly, with BIOT, when you get to the upper end of that offering, you need our voice -- or our transcript dream and voice stream to drive Einstein. And so that's really what's kind of driving a lot of the opportunities in the installed base with Salesforce and new logos.

Operator

Peter Levine, Evercore.

Peter Levine

Maybe just to double down, Mike, on your earlier comments. Can you maybe just talk about the transformation you're going through internally. One of the things you mentioned on the call, go-to-market initiatives to drive revenue growth, maybe just share with us what does that entail? Is it more partners? Do you -- are you coming across new buyers given it's more of an AI kind of world?
I mean, is the sale -- again, you talked a lot about sales cycles, but just curious, maybe just talk about what the operational review looked like and then some of the initiatives, especially when go-to-market (technical difficulty)

Michael Burkland

Yes. Great question, Peter. And again, transformational initiatives across top line and bottom line, right, to get on that path to Rule of 40 on a free cash flow basis. And if you think about the top line and the go to market, it really is I would say both product as well as go-to-market. And so we think about from a product standpoint, we're definitely investing much heavier into AI, showing in our innovation, some of the products we just announced are evidence of that, and there will be more.
But it's also a continuation of some of the sales execution and sales work changes we've made. But it's also top of funnel initiatives, Peter. I mean, again, I've been here 17 years, and I can tell you right now, there is a science to sales and marketing that we've always employed, so to speak, and -- you know what, we hire sales capacity based on our ability to grow top of funnel leads and opportunities. We've got a number of really exciting top-of-funnel initiatives that we are investing in.
Again, we're being very surgical about it. We're being very scientific about it, but there are some really exciting marketing initiatives that we're in the midst of I would say piloting. Again, we're being careful in terms of how much we spend. But so far, the early signs are very good in terms of lead flow increases, which to me is the leading indicator that has to drive our bookings growth. So I would say it's everything from the investments in product top-of-funnel marketing initiatives as well as sales execution initiatives and some of the things we've been working on as well as I would say, upsell into our installed base as well.
So when you think about new logos, that's really what I've already talked about. But if you think about penetrating our installed base, things like the AI Blueprint program as well as some of those changes we made to our CSM and AD or last year.

Andy Dignan

We're really driving a lot of opportunities with our top partners. You've heard a continuous drumbeat on new partnerships, strengthening partnerships and so a lot of focus on area as well.

Peter Levine

And for you, Bryan, can you maybe just share with us like how you stress tested the full year guide and I do know like the macro sensitive segments of the market that you guys are having in consumer, I mean, that drives a lot of upsell for you guys, and I think it's 3Q, 4Q, the back half. But again, there's still a lot of uncertainty, right? So if you think about what you're seeing today in the pipeline? Just walk us through like how you stress tested these numbers to kind of reinsure us that these are derisked?

Bryan Lee

Yes, absolutely, Peter. So -- if you think about it at the beginning of the year when we set the guide, we mentioned that we were assuming the seasonal uptick in the second half of this year, to be more muted than the strong seasonality that we saw in the back half of 2024.
Now given the increased uncertainty we have assumed that, that muted seasonality even slightly more muted than what we were originally assuming at the beginning of the year. And that's -- if we beat Q1 by $7.7 million against the midpoint of our guidance and essentially, we haven't put that through. So it gives us a little bit of that cushion.
Now on the headwind side, of course, we have the tough comparison of the largest customer that ran throughout, it's finishing its multiyear ramp throughout last year. So that still exists but there's also positive factors like our 32% enterprise AI revenue growth, and we expect that momentum to continue with some ebbs and flows throughout the year.
So -- and also, as Andy mentioned, enterprise installed base bookings coming in at the highest year-over-year growth rate in the last three years. So when you sort of net out all those positives and potential headwinds, that's how we landed at that unchanged midpoint of $1.14 billion.

Operator

Arjun Bhatia.

I'm [Will Miller] on for Arjun Bhatia. So maybe to double-click on is guidance derisked. In your prepared remarks, you talked about seeing some resistance of international companies using American vendors. How much of a risk is this? And in your conversations with these customers, are you able to reassure them enough that you can still win the deal?

Michael Burkland

Start. I think -- I guess, if you want to call this a silver lining. International represents about 12% of our business. So it's -- again, it's not a large portion, but it is greater than zero, so to speak. And again, I think it --we're seeing it more on the net new side than we are on the installed base side.
And Andy, you could speak a little bit to that.

Andy Dignan

Yes. I mean I think it's not all deals. And again, I think I mentioned also in the installed base and international to our existing customers. There's still a lot of, obviously, confidence in us. And the other part is, I mean, we are a strong global company, right?
We have coworkers and customers across the globe. And so how we treat our data, how we treat their data in terms of our architecture, we're able to have that kind of level of conversation. It seems to be right now, just a little bit of a -- for lack of a better term emotional in terms of just wanting to make sure that they fully understand what's going on. But confident that as some of that starts to dissipate over time that we'll continue to execute on the international front.

And in terms of the guidance being derisked, whether domestically or internationally, another way to look at it is bringing down the business between new logos and installed base contribution to the incremental revenue that we're guiding right? So right now, in the last three quarters of 2025, our guidance implies $67 million of incremental revenue.
And if you look at just the recurring revenue side of that, that's 93% of it or $62 million. So if we assume that DBRR stays at 107%, which we just reported in Q1 that implies that $52 million of that $62 million incremental revenue comes from our existing base.
And then the remaining $10 million is coming from new logos, but a vast majority of that is from new logos that are already in our backlog. So we have good visibility into the ramp of those revenue throughout the rest of the year. And a very small portion would come from the new logo go gets that would happen in the next month or two because the rest of it will impact 2026 revenue.

Pressing more on international. BT, that was a nice land you guys did over 1.5 years ago. How is that progressing now after this April 2 with the tariff announcement even though you're a software vendor, I'm just curious to see if there's any different interaction. The reason I bring it up is I spoke to a company in the UK that said their business really increased dramatically because they're a contact center based in the UK So I just wouldn't be helpful to get more color. .

Andy Dignan

Yes. I mean our relationship with BT continues to be strong. A lot of good activity continue to win deals. And certainly, we continue to lean heavily in international on our partners, right, because they sort of help balance out that story, BT making the investment with us. So I think they're -- we're just going to continue to execute with them and no real major change, I would say, in the business and the pipeline. We just got to keep executing together.

Samad Samana, Jefferies.

Samad Samana

Maybe first, just in terms of the partners that you guys mentioned, it's obviously like a really marquee list of great companies. I'm just curious, are any of these where there is a joint co-selling motion where the vendors are actually incentivizing their own sales organizations. Just trying to get a sense of how much distribution you're getting here beyond your own go-to-market efforts? And then I have one follow-up question.

Michael Burkland

Yes. I would say, Samad, that all of them have very, very healthy co-sell arrangements where we're just partnering so effectively in the field with our counterparts. I mean we've always been good at that, and we've always been great at that. And there are some incentives in some of those partnerships as well. But Andy, if you want to .

Andy Dignan

There is incentives and co-selling at both sides. I mean, each company kind of has a different approach in how they do these deals. But ultimately, across all of them, I can say there's incentive on both sides deliver. And a lot of times what comes with these partnerships is dedicated people on both sides working together to make sure that they're getting out in front of their -- obviously, these partners that we're talking about are very large sales forces. And so having dedicated people on their teams to make sure that they're out there pitching the joint value proposition. So yes, great relationships and incentives across the board.

Samad Samana

Very helpful. And then maybe just the medium-term operating model that's in the slide back, I think that's new, Bryan. I'm just curious what you're thinking about in terms of what the AI revenue contribution will look like as you march toward that? Maybe what assumption you've made? And the reason I'm asking is maybe how the gross margin of that revenue stream looks compared to the current gross margin stream and is that something that can maybe push gross margins even higher than where we are today?

Bryan Lee

Yes. No, thanks, Samad. So for the medium-term target, the 10% to 15% revenue growth has sort of a general momentum of AI that we are seeing today. No. So there is further upside in terms of potential revenue growth if AI acceleration really takes off.
Now from the gross margin perspective, you're right in that AI gross margin -- and our AI agent portfolio is a good representation of this because when we acquired Inference five years ago, the gross margin of that business is in the high 70s and low 80s and we've maintained that, if anything, we've actually improved it further. So as AI becomes a bigger mix of revenue, that should have a tailwind to overall gross margin on the subscription margin side as well as the total gross margin.

Michael Burkland

Sammad I have one other data point just to considering the mix here relative to AI, again, 20%-plus of our ACV enterprise bookings were AI in the last few quarters, right? So just that's another good number to kind of be able to triangulate what you're asking.

Tom Blakey, Cantor. .

Thomas Blakey

I think it's on the heels of maybe what Samad was just asking about what the kind of revenue looks like going further out. Obviously, no numbers or no kind of hard guidance here. But previously, Five9 is always kind of if you go back a couple of years, got it to 16%, that was the previous line, and then you beat that and grow in the 20s. Now we're 10% to 15%. So maybe talk about the level of kind of comfort you're in cushion you're putting into that 10% to 15% and what the revenue looks like today in the future from a consumption perspective, versus a [sell] perspective, from a partner perspective, like Samad just asked about AI.
So that's obviously going to go up as a percentage of revenue given its growth dynamic. But any of the type of color and what kind of cushion you're baking into that $10 million to $15 I think would be helpful.

Bryan Lee

Yes. So this is a result of the operational review that we just completed. And as Mike and Andy mentioned, we will continue to invest on the curve for our sales capacity and drive go-to-market initiatives. So that is what's reflected in this. The 10% to 15%, obviously, is two years out.
We have been growing in the 13% in the most recent quarter. We're guiding to 10% with slightly more prudent than in our guide than what we were originally thinking. So you can kind of triangulate using that because we haven't given specifics around what the beat level would look like and things like that, but you can triangulate using those data points.
From a pricing perspective, of course, our AI portfolio is all based on some type of consumption-based pricing, and that's going to become a bigger mix of our overall revenue. And so that will be a nice driver going forward as well. And as I mentioned earlier with Samad, if there's acceleration in the adoption of AI, then that will become a much bigger driver.

Michael Burkland

Tom to answer your last point there about partners, look, we continue to do more and more with partners. not just the strategic partners we're talking about, but also with just traditional channel partners, especially internationally, but even domestically. And so again, I think you'll continue to see us get more and more opportunities partners, but also just get more reach out of those partners.

Thomas Blakey

Okay. And just maybe just one quick follow-up on the transcript stream deal that you did there. And I know you've mentioned this a couple of times now, Mike, you seem awfully excited about it. I know you've given other color about the AI products sorry for the granular questions here. But IVA and Insights and [summaries ] are still leading the way here. Is there an anticipation that this could uptick here in the second half of calendar '25, that's it for me.

Michael Burkland

Yes. I think it's a good question, Tom. And again, when it comes to transcript stream and voice stream and those API layers, they're becoming much more important, especially in some of these partners partnerships. These strategic partnerships we've been enhancing and powering our partners to do more with our data but making sure we monetize that along the way, right? So again, we'll see it's a pretty small number today, but I do think -- that's another separate growth factor in a lot of ways.
And when we think about, again, the AI pie or the AI game, it's a team sport. We are going to be in accounts with Salesforce and ServiceNow and other CRM vendors, for example. And it's going to be some of ours, some of theirs, and we're going to monetize it when it's theirs.

Jim Fish, Piper Sandler. .

James Fish

I wanted to follow up on Peter's question. What are some of those top-of-funnel initiatives you're investing in? Is there a plan to change comp structures at all either?

Michael Burkland

Yes. I mean, look, we're always -- thanks, Fish. We're always looking at comp structures and commission plans and making sure that we've got the right incentives to drive the right behavior in terms of our go-to-market teams. We're always fine-tuning those comp plans.
So on an absolute basis, there's not going to be a whole lot of change, but there may very well be new metrics or KPIs that get introduced, especially in areas like our installed base sellers, right? They're selling into our base. Doing certain spits around AI, for example, in large enterprise making sure that we're also incenting not just one whale per rep, but a bunch of dolphins, right? So there are ways that we can incent the right behavior across our sales organization based on where we see the market opportunity. I hope that addressed that.

James Fish

That's helpful. And just a follow-up. Net retention rate slipped a little bit. I know it came in roughly where you were expecting, right? But for -- as we think about like the in-period number, it's down a little bit sequentially, and it seems as though the enterprise expansion rate was really the driver there.
So I guess what's given the comments that we're going to start to see stability here that, that you walked through the guide, Bryan, of the [ 52 out of 62 ] and so forth that we've actually hit bottom. Is there a way to think about cross-sell, upsell mix there, even trying of (technical difficulty)

Bryan Lee

Yes, absolutely, Jim. So if you think about the DBRR coming down to 17%, that was actually anticipated at the beginning of the quarter. So we had those tough comparisons I talked about with the mega customer and the seasonal downtick. So those two were the key drivers. If you look forward into Q2 and the remainder of the year, those tough comparisons still exist, but we have positive offsets as well.
The AI momentum and the 32% revenue growth that we just reported, Also, the 1 million-plus ARR customers have a much higher DBRR than the 107% that we just reported. And they're the fastest-growing category of our customer base. So those -- if you net it all out, we believe there will be fluctuations in either direction in small amounts throughout the year.

Meta Marshall, Morgan Stanley.

Meta Marshall

Great. Just on the elongating deal cycle. I just wanted to see, were there initiatives that you guys were putting in place that were maybe helping kind of quicker time to ROI for customers to kind of help offset that or just kind of help them see that they can kind of take this in smaller bites to maybe shrink those deal sales evaluation cycles?
And then maybe second, just on the fusion announcement with Salesforce. It sounds like that's kind of step one and kind of multi product initiative kind of over time, just kind of how we should see that relationship evolving, particularly kind of as it relates to agent force?

Andy Dignan

Yes. We've deployed within the sales teams a lot of focus around delivering AI and the platform at the same time in the new logo business. That's continued to go well. Really, when we talk about the elongation of sales cycles, it's more around just a couple of extra signatures, right? They're just more focused on the spend by companies.
It's not really anything we changed in our go-to-market, and we're continuing to execute well there. . On the Five9 Fusion, yes, really, the key focus right now with this is Salesforce, like we mentioned, is driving a lot of this BYOT opportunities to drive that into Einstein. If you think about further bring your own channel to be able to allow us to route all of the channels within the Salesforce platform and then certainly agent force. So that's kind of a journey as well. So this is kind of the start of that. We're excited about it, and this is only the beginning.

Rishi Jaluria, RBC.

Rishi Jaluria

Wonderful. I had two questions I wanted to ask continuing on the theme of AI. First, look, I appreciate all the metrics and disclosures you've given us around AI. I think it really helps kind of bolster the case that you can be real AI beneficiary.
Just for the sake of our own clarity and investor clarity, can you remind us what exactly is included in that bucket in terms of products and SKUs because the pushback I've always been getting from bears has been, "oh, there's a lot of basic automation included there. That's not truly AI." So I think a reminder there would be really helpful.
And then the second follow-on is, if we think about your medium-term target model, and again, I appreciate you putting that in the slide deck, you're guiding to a good amount of gross margin expansion, which is great to see. To what extent thinking about increased AI usage and adoption being a potential headwind to that gross margin number, just given how operatively expensive, these AI workloads are even post all the model efficiency that we've been seeing over the past six, nine months .

Michael Burkland

Yes. I'll start with the first question, Rishi, thank you for these questions are very good. So in terms of which products are included in our AI revenue, Look, the -- I don't want -- I want there to be no confusion. And I've said this before, no confusion. This does not include simple automation and other things, including WEM functionality that is not included in that. These are just the AI products since we acquired inference and the new ones we've announced that go along with that.
So whether it's AI self-service AI agents, as we call them today for either digital or voice, whether it's agent assist, summaries, transcriptions, it's all the new technologies and new products we've delivered that are AI focused. And it does not include any kind of simple automation that we had before that. So that's the best way I can answer that.
And when it comes to the medium-term model and our gross margin expansion and AI being a potential headwind as Bryan just said a few minutes ago, we actually see it just the opposite. We see AI as a tailwind. We talked about the gross margins in the rearview mirror back in the inference days, the model cost, the engine cost per interaction or cost per consumption has gone down dramatically.
And again, we're pretty efficient at the way we develop the software. So we expect that to be a tailwind, not a headwind.
I just want to say thank you for joining us. We look forward to keeping you apprised as we progress through the year and as we progress toward becoming a Rule of 40 company on a free cash flow basis. Again, in the future, but we're excited about the initiatives that are underway and the progress we're making. Thanks, everyone.
