Company Overview
Originally developed to address the growing complexity of IT security in the cloud era, Qualys (NASDAQ:QLYS) provides a cloud-based platform that helps organizations identify, manage, and protect their IT assets from cyber threats across on-premises, cloud, and mobile environments.
Revenue Growth
A company’s long-term sales performance is one signal of its overall quality. Any business can put up a good quarter or two, but the best consistently grow over the long haul. Over the last five years, Qualys grew its sales at a 12.9% 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.
We at StockStory place the most emphasis on long-term growth, but within software, a half-decade historical view may miss recent innovations or disruptive industry trends. Qualys’s recent performance shows its demand has slowed as its annualized revenue growth of 9.7% 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, Qualys reported year-on-year revenue growth of 9.8%, and its $175.6 million of revenue exceeded Wall Street’s estimates by 1.1%. Company management is currently guiding for a 8.8% year-on-year increase in sales next quarter.
Looking further ahead, sell-side analysts expect revenue to grow 7.3% over the next 12 months, a slight deceleration versus the last two years. This projection doesn't excite us and indicates 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.
Qualys’s billings came in at $168.3 million in Q1, and over the last four quarters, its growth was underwhelming as it averaged 9.2% year-on-year increases. This performance mirrored its total sales and suggests that increasing competition is causing challenges in acquiring/retaining customers. 
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 Qualys to acquire new customers as its CAC payback period checked in at 119.5 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 Qualys’s Q1 Results
We enjoyed seeing Qualys beat analysts’ EBITDA expectations this quarter. We were also glad its full-year EPS guidance exceeded Wall Street’s estimates. On the other hand, its EPS guidance for next quarter slightly missed, and this seems to be weighing on shares. The market seemed to be hoping for more, and the stock traded down 1.1% to $91.03 immediately following the results.
So do we think Qualys is an attractive buy at the current price? The latest quarter does matter, but not nearly as much as longer-term fundamentals and valuation, when deciding if the stock is a buy. We cover that in our actionable full research report which you can read here (it’s free).
