Business model and strategy
American Tower
How it makes money
American Tower owns the tower structure and controls the land beneath it, then leases vertical space to mobile operators such as T-Mobile, AT&T and Verizon so they can mount antennas. The economics turn on colocation: once a tower stands, adding a second or third tenant costs comparatively little, so incremental rent converts largely into operating profit.
Growth strategy
After selling its India business in 2024, American Tower concentrates capital on developed markets and on data centers. About 85% of planned 2026 discretionary capital spending goes to developed markets, including more than $700 million for CoreSite data center development, where revenue grew about 14% in 2025.
Competitive advantage
The advantage is the site itself. Zoning approval, environmental review and land control make a new macro tower slow and costly to add in a populated area, so a carrier that needs coverage in a specific location usually has to lease space on a structure that already stands there.
TCS
How it makes money
TCS earns revenue through global IT services and consulting, built around eight industry verticals and geographic diversification.
Growth strategy
TCS is growing through AI, cloud modernization, cybersecurity, data, engineering services, platforms, large transformation deals, partnerships and deeper penetration of existing enterprise accounts.
Competitive advantage
TCS' advantage is delivery scale, Tata trust, large-account depth, industry domain expertise, training infrastructure, strong margins and a reputation for mission-critical execution.
