IBM Shares Tumble After Another Quarterly Revenue Decline Meanwhile, total cloud revenue increased 10 percent to $7.5 billion, the most revenue from cloud yet for IBM. Bloomberg | Jan 22, 2021 Brody Ford (Bloomberg) -- International Business Machines Corp. shares fell the most in 10 months after the company reported a greater sales decline in the fourth quarter than analysts had expected, signaling Chief Executive Officer Arvind Krishna’s turnaround plan may take more time. Sales fell 6.5% to $20.4 billion in the three months ended Dec. 31, the Armonk, New York-based company said Thursday in a statement. That was below the $20.75 billion analysts had forecast, on average, and marked the 10th consecutive quarter with no year-over-year increase in revenue.
