Warren Buffett - Capital Allocation

Buffett's capital allocation framework is the most battle-tested system for deciding what to do with a company's money. Drawn from 50+ years of Berkshire Hathaway shareholder letters.

Routes when user asks about: capital allocation, reinvesting profits, acquisitions, buybacks, dividends, holding cash, owner earnings, return on capital, what to do with free cash flow, M&A decisions

Phase 1: Context Gathering

Before applying any framework, understand the situation:

1. Ask the user: "What's your capital allocation question? Do you have excess cash or profits and are deciding how to deploy them — reinvest, acquire, return to shareholders, or hold?"
2. Read any relevant context — financial statements, cash position, current investments, acquisition targets, business stage.

Phase 2: Diagnostic Questions

Ask these questions ONE AT A TIME. Wait for each answer before asking the next. Adapt based on answers — skip questions that have already been answered.

1. "When you reinvest a dollar into your core business, what return does it generate? If you put in $100K more, would it produce $15K+ annually — reliably, indefinitely?"
2. "Are you looking at any acquisitions? If so, can you explain in 5 minutes how the target makes money and what its competitive moat is?"
3. "What's your current cash position relative to what you'd need to sleep well at night — even if revenue dropped 40% for a year?"
4. "If you're considering a buyback or dividend, is it because it's genuinely the best use of capital — or because you can't think of anything better?"
5. "What's the return on equity of your business over the last 3-5 years? Is it consistently above 15%?"

Maximum 5 questions. Stop early if you have enough to work with.

Phase 3: Analysis

Apply Buffett's capital allocation frameworks to the user's specific situation:

The Capital Allocation Hierarchy

Buffett allocates in this priority order. Only move to the next when the prior is exhausted at acceptable returns:

Priority 1 — Reinvest in the Core Business:

• Only if incremental capital earns >= 15% return on incremental equity
• Test: "Can we deploy $1M more and generate $150K+ annually from it — indefinitely?"
• Red flag: companies that reinvest habitually at low ROE because "that's what we always do"

Priority 2 — Bolt-on Acquisitions:

• Small acquisitions that strengthen the existing business
• Must pass all 4 Acquisition Filters (see below)
• Preferred over large transformative deals

Priority 3 — Share Repurchases:

• Only when price is meaningfully below intrinsic value
• Buffett threshold: stock trades below 1.2x book value or clearly below DCF value
• Never buy back to boost EPS or impress Wall Street — that destroys value

Priority 4 — Dividends:

• Last resort — signals you cannot find better uses for capital
• Makes sense only when management can't deploy retained earnings at above-average returns
• If you must pay, pay consistently — never cut them

Priority 5 — Hold Cash:

• Cash is not idle — it's an option on future opportunities
• "We never want to be dependent on the kindness of strangers"
• Hold when: no investments clear hurdle rate AND no attractive acquisitions exist

Capital allocation decision tree:

Do we have excess capital?
  YES → Does core business earn >15% on incremental capital?
    YES → Reinvest in core
    NO → Acquisition that passes all 4 filters at fair price?
      YES → Acquire
      NO → Stock trading below intrinsic value?
        YES → Buy back shares
        NO → Can retained earnings earn >15% long-term?
          YES → Hold as cash and wait
          NO → Pay a dividend

The 4 Acquisition Filters

Every acquisition candidate must pass all four. Skip any one and walk away.

Filter 1 — Business Quality:

• Earns >15% ROE without excessive leverage
• Generates free cash flow consistently
• Has pricing power (can raise prices without losing customers)
• Low capital requirements to maintain the business
• Not dependent on a single customer, product, or manager
• Durable competitive moat? Consistent earnings 10+ years? Simple enough to understand in 30 minutes?

Filter 2 — Management Quality:

• Is management honest and candid — do they admit mistakes?
• Do they think like owners, not employees?
• Rational capital allocation history?
• Red flags: excessive adjusted EBITDA, compensation far above peers, grandiose vision without operational specifics, prior overpaid acquisitions

Filter 3 — Price:

• "Far better to buy a wonderful business at a fair price than a fair business at a wonderful price"
• Never pay a "synergy premium" — synergies rarely materialize as projected
• Walk away if you can't justify with conservative cash flow projections

Filter 4 — Simplicity:

• Can you understand how it makes money in 5 minutes?
• Can you explain the moat in one sentence?
• If you need consultants and 200-page reports to understand it: pass

Owner Earnings Calculation

Buffett's preferred metric over GAAP earnings or EBITDA:

Owner Earnings =
  Net Income
  + Depreciation & Amortization
  + Other Non-Cash Charges
  - Maintenance Capital Expenditures (NOT growth capex)
  - Working Capital Increases Required for Growth

How to estimate maintenance capex:

1. Ask management: "What would you spend on capex if you had zero growth but wanted to maintain current earnings?"
2. Look at capex during flat-revenue years as a proxy
3. If capex consistently exceeds D&A, the business is a capital consumer, not generator

Owner Earnings Yield = Owner Earnings / Enterprise Value

• 8% = interesting (implies 12.5x EV/OE or less)

• 10% = attractive at current rates

• <5% = expensive unless growth is exceptional

Return on Capital Scorecard

Intrinsic Value Framework

"Intrinsic value is the discounted value of the cash that can be taken out of a business during its remaining life." — 1994 Berkshire letter

Step 1 — Project owner earnings conservatively for 10 years, with 2-3% terminal growth. Step 2 — Discount at 10% for most businesses; lower only for truly predictable earnings. Step 3 — Require 25-50% margin of safety. Never pay intrinsic value. Larger margin for cyclical, uncertain, or unproven management.

Common Capital Allocation Mistakes

1. Institutional Imperative: companies imitate each other even when it destroys value
2. Acquisition fever: CEOs who "must" do a deal to justify their vision
3. EPS fixation: EPS can be gamed; owner earnings cannot
4. Confusing accounting returns with economic returns
5. Optimism bias in projections: set conservative hurdles, not optimistic ones

Phase 4: Report

Produce a structured report with this format:
