The five capital-allocation choices: (1) reinvest in the business through R&D and capex, (2) acquire other businesses, (3) pay dividends, (4) buy back stock, (5) repay debt. Choices 1 and 2 only create value when the return on the dollar deployed exceeds the firm's cost of capital. Choices 3, 4, and 5 are returning capital to claimants and require different judgments — buyback price discipline, dividend sustainability, and the marginal value of leverage relief.
| Use of capital | Test for value creation | Common failure mode |
|---|---|---|
| Reinvest in the business | Incremental ROIC > WACC | Empire-building capex at sub-WACC returns |
| Acquire another business | ROIC after synergies > WACC; price below historical-median multiple | Paying peak multiples at peak earnings |
| Pay dividends | Sustainable from free cash flow at 1.5x+ coverage | Borrowing to maintain a dividend the business cannot earn |
| Buy back stock | Price meaningfully below intrinsic value | Buying back peak prices to offset dilution from grants |
| Repay debt | Marginal cost of debt above marginal opportunity cost | Repaying cheap fixed-rate debt while taking on costlier short-term funding |
Worked example — Westmoor Optical, 2020-2024 capital allocation totaled $850M. Capex was $400M (47%) at a 9.2% incremental ROIC against an 8% WACC — value-creating, but only marginally. M&A was $250M (29%) across six deals at an average 14x EBITDA, when the industry was at 9x — value-destroying, even before integration risk. Dividends were $150M (18%) at 1.5x coverage — sustainable. Buybacks were $50M (6%) at an average price of $42 against an intrinsic estimate of $35-$50 — neutral. Debt repayment was $0. Practitioner read: the CEO is mediocre on capex, terrible on M&A, fine on dividends. The pattern of overpaying for M&A at peak multiples is the load-bearing red flag. Capital-allocation grade: 4 / 10.
Reinvestment Value Created = (Incremental ROIC − WACC) × Capital Deployed
Sit with the ideas.
Halton Industries generates $500M of free cash flow annually. The incremental return on capital expenditure is 6%, against a WACC of 9%. The CEO announces a $400M acquisition of a competitor at 12x EBITDA, when the industry's historical median multiple is 8x. From a capital-allocation standpoint, which framing is most defensible?
