Revenue growth
A company’s long-term revenue performance is one signal of its overall quality. Any business can deliver a good quarter or two, but the best consistently grow over the long haul. Over the last five years, Five9 grew its revenue at a 17.1% compounded annual growth rate. Though this growth is acceptable on an absolute basis, revenue growth alone is not enough for the software sector, which can display significant earnings volatility. The bar for the sector is particularly high, reflecting the non-essential and hit-driven nature of the products and services offered. Additionally, the five-year growth period starts around Covid, when revenue was depressed then rebounded.
Long-term growth matters most, but within software, a half-decade historical view may miss recent innovations or disruptive industry trends. Five9’s recent performance shows its demand has slowed as its annualized revenue growth of 11.3% over the last two years was below its five-year trend. Decelerating revenue growth in the sector warrants caution, as it could signal changing consumer tastes aided by low switching costs. 
This quarter, Five9 reported year-on-year revenue growth of 13.1%, and its $323.3 million of revenue exceeded Wall Street’s consensus estimates by 1.3%. Company management is currently guiding for a 10.2% year-on-year increase in revenue next quarter.
Looking further ahead, sell-side analysts expect revenue to grow 9.7% over the next 12 months, according to S&P, a slight deceleration versus the last two years. This underwhelming projection implies its products and services will face some demand challenges.
Billings
Billings is a non-GAAP metric that is often called “cash revenue” because it shows how much money the company has collected from customers in a certain period. This is different from revenue, which must be recognized in pieces over the length of a contract.
Five9’s billings came in at $335.7 million in Q3, and over the last four quarters, its growth was underwhelming as it averaged 11.6% year-on-year increases. This performance mirrored its total revenue and suggests that increasing competition is making it harder to acquire and retain customers. 
Customer acquisition efficiency
The customer acquisition cost, or CAC, payback period represents the months required to recover the cost of acquiring a new customer. Essentially, it’s the break-even point for sales and marketing investments. A shorter CAC payback period is ideal, as it implies better returns on investment and business scalability.
It’s relatively expensive for Five9 to acquire new customers as its CAC payback period was 53.1 months this quarter. The company’s slow recovery of its sales and marketing expenses indicates it operates in a highly competitive market and must invest to stand out, even if the return on that investment is low.
Key takeaways from Five9’s Q3 results
Five9’s guidance put a weaker cast on its Q3 results: EPS forecasts for both next quarter and the full year fell short of Wall Street’s consensus estimates. Those shortfalls contrasted with beats on adjusted operating income and billings this quarter. Overall, it was a weaker quarter, and shares plunged 19.8% to $27.40 immediately after the release.
