HubSpot Just Cut Its Own Customer-Growth Forecast to 5,000 a Quarter. What Is the Stock Worth in 3 Years?

Non-GAAP (adjusted) operating income climbed 44% to $185.3 million, lifting the adjusted operating margin to 20.3% from 17% a year ago. And free cash flow reached $167.9 million, up from $116.2 million.

The arithmetic of the customer base is where the change lands. HubSpot ended June with 306,446 customers, up 14% year over year. Add 5,500 a quarter, the middle of the new range, and that base grows about 7% a year instead of the roughly 12% the old assumption implied.
