Microsoft gains on buyback, dividend increase

Microsoft stock added 0.6% after it announced plans to increase the quarterly dividend 10% to 83 cents a share, up from 75 cents. 

The new dividend is payable Dec. 12 to holders of record Nov. 21. The annual meeting is set for Dec. 10. The software and cloud-services giant also approved a new $60 billion share repurchase program.

The decision followed Microsoft’s announcement in July to boost its investment in artificial intelligence. Microsoft’s July earnings report missed analysts’ estimates for cloud revenue. The segment makes up nearly all Microsoft’s capital expenditures.

“It provides our external foundry customers and suppliers with clearer separation and independence from the rest of Intel,” CEO Pat Gelsinger said in a statement Monday about the new subsidiary structure. 

Industry observers had said that potential customers for Intel’s services were nervous about turning over their intellectual property to a manufacturer that was also a rival, according to MarketWatch columnist Therese Poletti.
