By the end of July 31, the company had approximately 191,600 enterprise customers.

Nearly 4,000 customers each contributed over $100,000 in revenue over the past 12 months. The number of high-revenue clients represents an increase of about 7.1% compared to a year ago.

Zoom’s CFO, Kelly Steckelberg, will resign from her position on October 31.

Snowflake plunges despite earnings beat

Snowflake stock tumbled 13% even after the company beat quarterly expectations and raised its full-year revenue guidance.

Snowflake reported fiscal second-quarter revenue of $868.8 million, representing 29% year-over-year growth and surpassing the analysts’ estimate of $851.6 million.

Adjusted earnings of 18 cents per share came higher than analysts’ 16 cents forecast but down from the 22 cents a year ago.

The company expects a 26% growth in its product revenue for the current quarter.

Morgan Stanley analysts say the Q2 results were "solid," but the decelerating growth trajectory "likely fails to address existing bear cases around rising competitive intensity."

The company’s product revenue growth for Q1 was 34%.

Urban Outfitters plummets after mixed financial results

Urban Outfitters stock lost nearly 10% after the company reported an earnings beat and a decrease in same-store sales.

Wells Fargo analyst Ike Boruchow lowered Urban’s price target to $40 from $48 and kept an equal weight rating, citing concerns over the mid-July sales slowdown and higher-than-expected inventory levels.

“Second half of the year numbers are coming down, and this read-through likely takes softlines retail down on Thursday,” Wells said.
