Reinvestment Runway

Overview

Determine whether attractive economics can be repeated at meaningful scale and for long enough to matter. Treat market_growth_pack.external_growth_runway as an external opportunity input, not proof of economic runway. Prioritize Incremental economics over historical averages and separate core-engine quality from management capital allocation quality.

Required investigation

1. Reconstruct where retained cash and external capital have been deployed: organic investment, working capital, R&D/CAC, acquisitions, debt, buybacks, dividends, cash, SBC, and equity issuance.
2. Estimate incremental/marginal returns using the best unit/cohort/corporate evidence; distinguish them from average historical ROIC and respect economic lags. When economic_engine_pack carries dual return_bases, carry both forward — an incremental return quoted on one basis and compared with a cost of capital on the other is meaningless.
3. Evaluate capital allocation behavior: actual vs stated priorities, acquisition-cohort returns, net dilution/buyback effects, leverage, incentives, governance, and related parties where material. Purchases of listed minority stakes are capital allocation decisions and are judged here, using look_through_earnings and associate_cash_bridge from upstream rather than recomputing them.
4. Test repeatability. For a product-cycle business, require evidence across generations rather than treating one hit launch as a reusable reinvestment unit.
5. Reconcile market_growth_pack category/share/channel/geographic evidence with unit returns and capital needs. Map the reinvestment opportunity set from external growth runway, penetration, economic capacity, realistic share, scale economics, and constraints—not headline TAM.
6. Analyze Duration/CAP through moat outcomes and identify mechanisms that could cause return decay.
7. Assess financial resilience and financeable runway: working-capital needs, liquidity, debt/refinancing, external-funding dependence, and dilution risk.
8. Apply Emerging Compounder methods when history or accounting returns are immature; use unit economics, mature-economics bridges, and evidence trajectory rather than age penalties.
9. Report Evidence Maturity independently from potential and pass material contradictions/data gaps forward.
