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, Integral Ad Science grew its sales at a 16.7% 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. Luckily, there are other things to like about Integral Ad Science.

This quarter, Integral Ad Science reported year-on-year revenue growth of 17.1%, and its $134.1 million of revenue exceeded Wall Street’s estimates by 3.5%. Company management is currently guiding for a 10.8% year-on-year increase in sales next quarter.
Looking further ahead, sell-side analysts expect revenue to grow 10.1% over the next 12 months, a deceleration versus the last three years. Still, this projection is above the sector average and suggests the market sees some success for its newer products and services.
