Revenue Growth
A company’s long-term sales performance is one signal of its overall quality. Any business can have short-term success, but a top-tier one grows for years. Over the last five years, Bandwidth grew its sales at a 15.2% 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. Bandwidth’s recent performance shows its demand has slowed as its annualized revenue growth of 11.5% 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, Bandwidth reported year-on-year revenue growth of 19.8%, and its $208.8 million of revenue exceeded Wall Street’s estimates by 3.6%. Company management is currently guiding for a 20.5% year-on-year increase in sales next quarter.
Looking further ahead, sell-side analysts expect revenue to grow 12% over the next 12 months, similar to its two-year rate. This projection is underwhelming and implies its newer products and services will not accelerate its top-line performance yet.

Customer Acquisition Efficiency
The customer acquisition cost (CAC) payback period measures the months a company needs to recoup the money spent on acquiring a new customer. This metric helps assess how quickly a business can break even on its sales and marketing investments.
It’s relatively expensive for Bandwidth to acquire new customers as its CAC payback period checked in at 62.1 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 Bandwidth’s Q1 Results
We were impressed by how significantly Bandwidth blew past analysts’ EBITDA expectations this quarter. We were also glad its revenue guidance for next quarter exceeded Wall Street’s estimates. On the other hand, its EBITDA guidance for next quarter missed. Overall, we think this was a decent quarter with some key metrics above expectations. The stock traded up 28.5% to $31.10 immediately after reporting.
Indeed, Bandwidth had a rock-solid quarterly earnings result, but is this stock a good investment here? 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).
