SpaceX is generating significant value through rapid expansion of Starlink broadband service and establishing itself as a leading launch provider with reusable technology. 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. This drug class should become the standard of care for both diabetes and obesity and grow to at least a $150 billion category. The market is in early innings of uptake with adoption driving Lilly to nearly double revenues by 2030. Microsoft has built a $135 billion run-rate cloud business including Azure cloud infrastructure and Office 365 applications. The company remains well positioned across overlapping software, cloud computing, and AI landscapes with its vertically integrated technology stack and broad sales distribution, driving durable long-term double-digit growth.

Spotify continues to demonstrate double-digit user growth and industry-leading engagement levels with evident pricing power as customer retention held despite recent price hikes.
