Company Overview
Founded in 2002 by three cybersecurity veterans, Tenable (NASDAQ:TENB) provides software as a service that helps companies understand where they are exposed to cyber security risk and how to reduce it.
Sales Growth
Reviewing a company’s long-term sales performance reveals insights into its quality. Even a bad business can shine for one or two quarters, but a top-tier one grows for years. Over the last three years, Tenable grew its sales at a 16.9% annual rate. Although this growth is acceptable on an absolute basis, it fell slightly short of our standards for the software sector, which enjoys a number of secular tailwinds.

This quarter, Tenable reported year-on-year revenue growth of 10.7%, and its $239.1 million of revenue exceeded Wall Street’s estimates by 2.4%. Company management is currently guiding for a 9.4% year-on-year increase in sales next quarter.
Looking further ahead, sell-side analysts expect revenue to grow 8.4% over the next 12 months, a deceleration versus the last three years. This projection doesn't excite us 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 72.8 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
It was encouraging to see Tenable beat analysts’ revenue expectations this quarter. We were also glad its revenue guidance for next quarter slightly exceeded Wall Street’s estimates.

The stock traded down 10.5% to $30.14 immediately after reporting.
