Revenue growth
A company’s long-term performance is an indicator of its overall quality. Any business can have short-term success, but a top-tier one grows for years. PubMatic’s 7.7% annualized revenue growth over the last five years was sluggish, falling short of the software sector benchmark.
Long-term growth is the most important, but within software, a half-decade historical view may miss new innovations or demand cycles. PubMatic’s recent performance shows its demand has slowed as its annualized revenue growth of 1.8% over the last two years was below its five-year trend. Such decelerations in revenue growth warrant caution, as they could signal changing consumer tastes aided by low switching costs. 
This quarter, PubMatic reported year-on-year revenue growth of 17.1%, and its $79.58 million of revenue exceeded Wall Street’s consensus estimates by 4.6%. Company management is currently guiding for a 14.9% year-on-year increase in revenue next quarter.
Looking further ahead, sell-side analysts expect revenue to grow 8.5% over the next 12 months, according to S&P. While this projection suggests its newer products and services will spur better top-line performance, it is still below average for the sector.
Customer acquisition efficiency
The customer acquisition cost, or 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.
PubMatic is efficient at acquiring new customers, and its CAC payback period was 31 months this quarter. The company’s relatively fast recovery of its customer acquisition costs means it can attempt to spur growth by increasing its sales and marketing investments.
Key takeaways from PubMatic’s Q3 results
PubMatic’s outlook was a highlight of a solid quarter: Full-year EBITDA guidance came in well ahead of analysts’ consensus estimates, and next-quarter EBITDA guidance also topped Wall Street’s consensus. Investors were likely hoping for more, however, as shares fell 2.3% to $18.58 immediately after the release.
