Inuvo (INUV) said late Wednesday it expects to report Q4 net revenue of about $14 million on March 5, down 47% from a year ago.

"The shortfall was driven primarily by an intentional pullback in the Platform product line," the firm said.

Shares sank 30% following an increase in intraday trading volume to over 901,000 from a daily average of about 160,000.

United Rentals (URI) reported Q4 adjusted earnings and revenue below market expectations.

Shares of the company were down 15%, with intraday trading volume at over 1.64 million, versus the stock's daily average of about 625,000.

Microsoft (MSFT) Azure's 38% growth on a constant-currency basis while exceeding the firm's guidance by 1 percentage point still disappointed investors, a Morgan Stanley note said.

Microsoft's disclosure that OpenAI represents 45% of commercial remaining performance obligations was a first-time disclosure, and the software giant provided no specific historical comparisons for that percentage of commercial RPO from the OpenAI relationship, according to a note from Truist Securities.

Shares of Microsoft, which beat on fiscal Q2 adjusted earnings and sales, still sank 12%, with intraday trading volume surging to over 89.5 million from a daily average of about 25.3 million.
