Five9's New CEO Puts the AI Story on a Fast Track — and a $200M Buyback Behind It
Subscription growth accelerates to 13%, AI revenue leaps 68%, and a consumption-based model moves from pitch to practice.

The New CEO's First Full Quarter
Amit Mathradas, who took over as CEO in February, used his first full earnings call to frame a turnaround story around four priorities: culture, operations, core stabilization and AI-led growth. The market, which had already pushed the stock up sharply off a 2025 low (recent 90-day return +140.6%), gave the narrative a strong grade: subscription revenue accelerated to 13% year-over-year (second consecutive quarter of acceleration), and the company beat the high end of guidance on both revenue and EPS. “We are seeing signs that our strategy is working. In the first quarter, we posted our second consecutive quarter of year-on-year accelerating subscription revenue growth” — Amit Mathradas, CEO · 2026-04-30 — evidence that the core business is no longer just stabilizing, but inflecting.
From Seat Count to Consumption: A New Model Pivot
The most substantive structural move is away from the traditional seat-based pricing model. Five9 is shifting to fixed revenue commitments, allowing customers to fill committed dollars with AI tools as seat counts compress. The company framed this as a shift from selling seats to selling outcomes.
Our path to success is no longer about simply selling seats. Instead, it is about selling a complete solution based on capabilities and consumption.
That transition is already showing up in the numbers: the LTM dollar-based retention rate stabilized at 105% (subscription DBR at 107%), and management expects the metric to inflect higher in the second half as the backlog converts. Seat count concerns have long been the bear case for Five9; the company is now trying to make them almost irrelevant by redefining the monetization surface.
AI: The Acceleration Engine
AI revenue is the clearest sign of reacceleration. The company disclosed that AI revenue grew 68% to an annual run rate over $125 million (now ~13% of total subscription revenue, up from ~8% a year ago). “AI revenue grew 68% to an annual run rate of over $125 million” — Brian Lee, CFO · 2026-04-30 This compares to 49% growth in Q4 and 41-50% in the prior calls. The backlog is converting earlier than expected, which gives management confidence to raise full-year revenue guidance to a midpoint of $1.26 billion. AI revenue is now the company's highest-velocity product line, and management expects it to exceed 40% growth for the full year. Customers are increasingly adopting AI as part of the platform rather than as point solutions, which management argues expands the TAM and deepens the competitive moat. “Everyone is talking about agentic; at Five9, we are talking about humanic, which is the combination of humans and agents doing things that have not been thought about before.” — Amit Mathradas, CEO · 2026-04-30 This "humanic" positioning is aimed at deflecting the fear that AI will simply cannibalize the core CCaaS business.
Discipline, Margins, and a New Capital Return
The other big change is financial discipline. The company noted a 470 basis point EBITDA margin expansion from 2024 to 2025, and Q1 2026 EBITDA margin came in at 24%. Operating margin hit 6.7% in Q1 2026, up 8.7 points year-over-year. This is a company that was losing money as recently as 2024. The new CEO is also making organizational design changes — reducing spans and layers, hiring a chief marketing and growth officer (Jay Lee), and completing deep dives across the product portfolio. Organizational design is now a key focus, with the goal of speeding up decision-making and improving execution. On capital allocation, Five9 repurchased $10 million in Q1, will complete the $90 million ASR by Q3, and the board authorized a new $200 million buyback. “After repurchasing $10 million of shares in the first quarter, we intend to enter into an accelerated share repurchase program for the remaining $90 million under the current authorization, which we expect to be completed by Q3. The board has also approved a new share repurchase program of $200 million, which we expect to execute opportunistically.” — Brian Lee, CFO · 2026-04-30 This is a clear signal of confidence and a reinforcement of the intrinsic-value story.
What's Priced In
The stock has run from a ~$10 level (post-2021 drawdown of -84%) to $34.5, still far below 2021 highs. With Q1 results and a back-half acceleration guide, the market is starting to buy the inflection. But the narrative hinges on execution: can AI growth stay above 40% while CCaaS revenue holds around 8%? The second-half guide implies double-digit total revenue growth driven entirely by backlog — no dependence on new go-get logos. That is a strong visibility signal. AI tools are increasingly the driver of renewal conversations, and the pivot to consumption-based commitments reduces the risk of seat erosion. The key risk is that AI growth remains lumpy and the transition to revenue commitments takes longer than expected, but for now the market is giving the new CEO the benefit of the doubt.
