Axon Cloud & Services is now nearly the company's biggest segment as its revenue grew 62.4% to $132.6 million due to demand for its premium Officer Safety Plan-integrated bundles. Digital evidence, meanwhile, continues to be the primary driver for growth in the high-margin software business. Net revenue retention increased 122% in the quarter, meaning existing customers increased their spending on Axon Cloud by 22% over the last four quarters.

Now what

The company raised its full-year revenue outlook to a range of $1.51 billion to $1.53 billion, or 27% to 29% growth, up from a previous range of $1.44 billion to $1.46 billion. The increase came from improving confidence in demand for the Taser 10 and Axon Body 4. 

The company continues to expect an adjusted EBITDA margin of 20%, but margins should expand next year as its new products mature.

Axon has been a long-term outperformer and after a strong beat on the top and bottom lines and a revenue guidance raise, it's not surprising to see the stock jumping last month.
