The Company

Five9 (FIVN) is a cloud Contact Center as a Service (CCaaS) platform. It provides omnichannel contact center software and AI-powered automation to manage customer interactions across voice, chat, email, SMS, and social channels.

Financials

Bull Case

Advances in AI allows Five9 to offer much richer customer experiences. Customers can save overall costs by switching to solutions like Five9 where most of the cases are handled by AI and having to hire fewer human agents.
Management is projecting revenue growth to reach 15% from the current 9% by 2027. Given their 25% EBITDA profitability, it would give them a Rule of 40 score of 50 by 2027.
While the latest Q1 2026 overall only saw revenue growth of 9%, AI revenue itself management noted grew 68%.
Management is expecting that the TAM for CCaaS plus support AI is nearly 2x the displacement of seats that will happen.
Stock is very cheap at the current valuation of 1.5Bill$. PE ratio is 6.
Management is showing confidence in their outlook by commissioning 200Mill$ in buy backs which is significant for the size of the company.
The companies seat based legacy business is still growing and AI is becoming a much faster, smaller growth segment. There are still a large number of customers who are still on prem. Transition of these customers to cloud continues to support the older non AI revenue.

Bear Case

There is intensifying competition from larger platforms and bundling by adjacent vendors who are traditional UCaaS players. AI makes it easier for players like Amazon to have competing offers at lower prices.
Five9 product also serves seat based human agent CCaaS. As use of AI by customers increases, it will cannibalize the seat based revenue. Yet to be seen if the AI revenue can overcome the loss in the legacy revenue.

Management Outlook

Historically, contact center spending has been overwhelmingly weighted towards labor, creating a difficult trade-off between lowering costs and delivering better experiences. AI is acting as a catalyst to change this. Customers now see the potential to reallocate a portion of their labor spend to fund the combination of AI and enhanced CX.
as AI handles a large share of routine customer requests, the role of agents is elevated, not eliminated. People become experts who manage complex escalations. human-based intelligence and case resolution provide a critical feedback loop for training AI agents
As AI reduces the customer’s traditional labor spend, that budget shifts towards technology. We believe this fundamentally expands our monetizable surface area by enabling entirely new use cases and more customer experiences.
In the first quarter, we posted our second consecutive quarter of year-on-year accelerating subscription revenue growth (13%), an important indicator that the core business is strengthening. Our subscription revenue grew 13% year over year. This was driven by our CCaaS revenue, which grew 8%, and our AI revenue, which grew 68% to an annual run rate of over $125 million.
We are also seeing customers adopt our AI solutions in production as an integrated part of our CX platform, leading to multiple quarters of strong AI revenue growth.
we intend to complete the remaining amount of our $150 million share repurchase authorization by the end of Q3. In addition, our board has authorized an additional $200 million share repurchase program.
As AI replaces seats, those dollars are not leaving the contact center; they are getting reallocated towards software. Companies are looking to platforms like us that can marry voice, digital, and AI and present it in a format where it is all connected under one roof, allowing them to get far larger outputs in efficiency through that system.
The TAM for CCaaS plus support AI is nearly 2x the displacement of seats that will happen, and so we now get to play in a much larger market as we evolve and build into this platform.
the seat count continues to grow at a healthy rate, relatively in line with the CCaaS revenue growth that we had provided. If you look at the backlog of our customers that we have already won, there is a large portion that is CCaaS-oriented and a smaller but fast-growing portion that is AI. So definitely, the seat growth from a customer perspective has been healthy
There are still a vast number of customers on-prem, and eventually they will have to make that decision to move to the cloud.

How CCaaS is changing with AI

A typical U.S. company would:

Buy CCaaS software from Five9/NICE/Genesys
Hire thousands of agents in India, Philippines, Mexico, etc.
Those agents answer customer calls using the CCaaS platform

Example:

Bank of America uses Five9
5,000 agents in India
Agents use Five9 software

Five9 gets paid for software.
The BPO (outsourcing company) gets paid for labor.

Who Owns Those Call Centers?

Large public companies include:

Teleperformance
Concentrix
Genpact
TaskUs
WNS Holdings

These firms employ hundreds of thousands of agents globally.

What AI Changes

Before:

Customer call
Human in India answers
Cost = $5-$15/hour

Now:

AI answers first
Human only handles difficult calls

Result:

A company that needed 1,000 agents may only need 600.
