Company Overview

Revenue Growth
A company’s long-term sales performance can indicate its overall quality. Even a bad business can shine for one or two quarters, but a top-tier one grows for years. Over the last five years, Tenable grew its sales at a 17.3% compounded annual growth rate. Though this growth is acceptable on an absolute basis, we need to see more than just topline growth for the software sector, which can display significant earnings volatility. This means our bar for the sector is particularly high, reflecting the non-essential and hit-driven nature of the products and services offered. Additionally, five-year CAGR starts around Covid, when revenue was depressed then rebounded.
Long-term growth is the most important, but within software, a half-decade historical view may miss new innovations or demand cycles. Tenable’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. We’re wary when companies in the sector see decelerations in revenue growth, as it could signal changing consumer tastes aided by low switching costs. 
This quarter, Tenable reported year-on-year revenue growth of 9.6%, and its $262.1 million of revenue exceeded Wall Street’s estimates by 1.2%. Company management is currently guiding for a 7% year-on-year increase in sales next quarter.
Looking further ahead, sell-side analysts expect revenue to grow 6.5% over the next 12 months, a deceleration versus the last two years. This projection is underwhelming and implies its products and services will face some demand challenges.

Customer Acquisition Efficiency
The customer acquisition cost (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 Tenable to acquire new customers as its CAC payback period checked in at 110.9 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 Tenable’s Q1 Results
We were impressed by Tenable’s optimistic EPS guidance for next quarter, which blew past analysts’ expectations. We were also glad its full-year EPS guidance trumped Wall Street’s estimates. On the other hand, its full-year revenue guidance missed. Overall, this print had some key positives. Investors were likely hoping for more, and shares traded down 5.8% to $20.25 immediately following the results.
So do we think Tenable is an attractive buy at the current price? If you’re making that decision, you should consider the bigger picture of valuation, business qualities, as well as the latest earnings. We cover that in our actionable full research report which you can read here (it’s free).
