The company is making tremendous progress on Starship, the largest most powerful rocket ever flown, representing a significant leap forward in space exploration capabilities. Eli Lilly's portfolio of Mounjaro/Zepbound GLP-1/GIP drugs are important treatments for diabetic and non-diabetic obese patients.

Microsoft has built a $135 billion run-rate cloud business including Azure cloud infrastructure and Office 365 applications.
