INTUIT INC. (INTU) — Investment Memo
🐂 The Bull Case (Warren's voice)
The Ultimate Financial Toll Bridge: Intuit doesn't just sell software; it owns the financial operating system for the American small business. Once a business integrates its payroll, taxes, and ledger into QuickBooks, the cost of leaving is not just monetary—it's a chaotic operational nightmare. That is a moat we love.
Pricing Power by Default: When your product is the "single source of truth" for a company's taxes and payroll, you can raise prices incrementally without triggering a mass exodus. The customers stay because the pain of switching exceeds the pain of a price hike.
The Credit Karma Synergy: By moving into the "financial health" space, Intuit is capturing the user before they become a business owner or while they are managing personal wealth, creating a closed-loop ecosystem of data.
Cash Machine: FCF of $6.1B against a NI of $3.9B tells me the accounting is conservative and the cash is real. We prefer a business that prints cash over one that reports "adjusted" earnings.
Attractive Entry: This becomes a Berkshire-grade investment if the price reflects a reasonable multiple of that cash flow, rather than a "hope and prayer" multiple based on AI hype.
🐻 The Bear Case (Charlie inverts)
The "Direct File" Guillotine: The IRS is finally waking up. If the US government successfully implements a seamless, free, direct-filing system for taxes, TurboTax's primary moat becomes a liability. Why pay a toll to the government when the government provides a free road?
The AI Paradox: Intuit bets heavily on AI to automate bookkeeping. However, if AI makes accounting too easy, the "expertise" gap Intuit charges for vanishes. LLMs could potentially turn a complex accounting task into a commodity prompt, stripping away the switching costs.
The ROE Decay: ROE has plummeted from 65.6% to 19.6%. While the business is scaling, the efficiency of the capital is leaking. The Credit Karma acquisition added massive debt ($6.9B) and complexity—it's possible they overpaid for a growth engine that doesn't compound as cleanly as the core software.
Most Likely Threat: The IRS Direct File. Timeframe: 3–7 years. It is a structural, legislative threat that no amount of marketing can solve.
💰 Valuation & Margin of Safety
The business is exceptional, but the price is a different story.
Intrinsic value estimate: $291.17 per share
25% margin of safety entry: $218.38(conservative)
50% margin of safety entry: $145.59(Buffett's ideal)
Current Status: Expensive.Based on the DCF, the market is currently pricing in growth rates and terminal values that far exceed the conservative 8% FCF growth projected here. We are paying for a future that hasn't been proven yet.
Verdict: PASS
The moat is wide, but the price is delusional. We do not buy great businesses at "perfect" prices. Wait for a structural panic or a government-led valuation reset before stepping in.
