Ackman Takes Microsoft Stake, Calls Tech ‘Deeply Embedded’

Bill Ackman said Pershing Square has built a new stake in Microsoft Corp., taking advantage of a decline in the company’s share price to invest in a business that he said is stronger and more resilient than investors think.

The hedge fund has made Microsoft a core holding, Ackman said in a post on X on Friday, calling its 365 suite of products including Word and Excel and its Azure cloud service “two of the most valuable franchises in enterprise technology.” Pershing Square began building a position in the company in February and will disclose the stake in a regulatory filing Friday, he said.
