The Business
- Microsoft Corporation (MSFT) is the world's largest software company and second-largest cloud computing provider, founded by Bill Gates and Paul Allen in 1975. The company operates across three segments: Productivity & Business Processes (Microsoft 365, LinkedIn, Dynamics), Intelligent Cloud (Azure, SQL Server, Windows Server), and More Personal Computing (Windows, Xbox, Surface, Search). Microsoft's competitive advantage rests on its dominant position as the enterprise productivity infrastructure standard — Windows, Office, Teams, and Active Directory are deeply embedded in virtually every large organization globally.
- Azure is growing 30%+ as enterprises migrate to the cloud, accelerated by AI workloads. The $13B OpenAI partnership provides Microsoft exclusive commercial rights to GPT-4/5, integrated across all products as Copilot. FY2024 (June year-end) revenue was $245B (+16%), net income $88B (+22%), operating margin 45%, and free cash flow $74B.
- Revenue is 95%+ recurring through subscriptions. Market cap exceeds $3 trillion. Microsoft employs ~228,000 people.
Why They Own It
“Chris Hohn: 'We invest in businesses with the strongest competitive positions — companies where we have high confidence the business will be just as dominant in 10-20 years as it is today.'”
- Chris Hohn's $8.1B Microsoft position (15.1% of TCI) reflects his concentrated ownership of monopoly-quality businesses. Microsoft possesses three compounding moats that are each individually dominant: (1) Windows + Office/Microsoft 365 — an enterprise productivity monopoly with 1.5B+ users generating massive recurring subscription revenue, (2) Azure — the #2 cloud platform (growing 30%+) capturing enterprise IT spending migration, and (3) the OpenAI partnership — a $13B investment giving Microsoft exclusive commercial rights to the most advanced AI models, integrated across every Microsoft product.
- The enterprise software switching costs are arguably the highest of any business in the world: no Fortune 500 company can realistically migrate away from Microsoft's productivity suite, Active Directory, or Azure without years of disruption. Hohn values this durability above all else.
- FY2024 revenue was $245B with 45% operating margins and $74B free cash flow — among the highest-quality earnings streams in corporate history. Azure AI services revenue is growing 100%+ annually, suggesting Microsoft may be the largest winner from the AI capex supercycle.
- At 33-35x earnings, the valuation reflects quality, but Hohn's framework accepts premium multiples for businesses with effectively permanent competitive positions.
What the investor sees
At $8.1B and 15.1% of TCI's portfolio, this is Hohn's third-largest position. Microsoft trades at roughly 33-35x FY2024 EPS of $11.80 and roughly 28x consensus FY2026 estimates. Hohn's return math: (1) 14-16% revenue growth (Azure AI acceleration + M365 pricing + LinkedIn + gaming), (2) 100-200bps of margin expansion from Azure scale and AI monetization, (3) 1-2% buyback yield, and (4) 0.7% dividend yield. Total return: 14-16% revenue growth + 1-2% margin expansion + 1.5% buyback + 0.7% dividend = 17-20% expected annual return. By FY2030, EPS could reach $25-30, and at a 25-30x terminal multiple, the stock would be $625-900. The premium multiple is justified by the business quality — Microsoft's revenue is 95%+ recurring, with gross margins above 70% and the most defensible competitive position in technology.

The Moat
- Enterprise software monopoly — Windows + Office/M365 are the standard productivity infrastructure for virtually every business in the world. Migration costs are enormous
- Azure cloud platform — #2 cloud behind AWS with 30%+ growth, accelerated by AI workload demand. Enterprise customers already running on Azure face high switching costs
- OpenAI partnership — exclusive commercial rights to the most advanced AI models (GPT-4, GPT-5), integrated across every Microsoft product as Copilot
- Developer ecosystem lock-in — GitHub (100M+ developers), Visual Studio, .NET framework create deep developer platform dependency
- Active Directory/Entra ID — enterprise identity and security infrastructure that is extremely difficult to replace, creating deep organizational lock-in
- Network effects across the stack — Teams, SharePoint, Exchange, LinkedIn all interconnect, making the cost of switching any single product much higher
- 95%+ recurring revenue — subscription model provides predictable, growing revenue with annual price increases
What Could Go Wrong
AI capex intensity — $44B+ annual capex may not generate proportional returns if AI monetization disappoints
OpenAI relationship risk — if OpenAI develops competing distribution or renegotiates commercial terms, Microsoft's AI advantage could erode
Antitrust/regulatory risk — EU Digital Markets Act, FTC scrutiny of Activision acquisition, potential cloud computing regulations
Premium valuation (33x+ earnings) provides minimal downside protection if growth decelerates
Cloud competition from AWS and Google Cloud — while Microsoft is growing, so are competitors, and cloud margins face pricing pressure
Enterprise spending slowdown — in a recession, companies may delay cloud migration and reduce software spending
Catalysts
- AI Copilot monetization — Copilot for M365 ($30/user/month) represents a massive upselling opportunity across 400M+ commercial seats
- Azure AI revenue acceleration — enterprise AI workloads driving 100%+ growth in AI services, with Azure increasingly chosen as the default AI infrastructure
- GitHub Copilot adoption — developer AI tools generating incremental subscription revenue with 70%+ retention rates
- M365 pricing power — annual price increases of 10-15% across enterprise licenses with near-zero churn
- Gaming/Activision Blizzard — $69B acquisition provides subscription revenue growth through Game Pass
- Share buyback program — Microsoft returns $25B+ annually through buybacks, reducing share count ~1.5% annually
