Capex & reinvestment-runway analysis
You want to understand how much a company must reinvest and whether growth is self-funding.
The prompt — copy and run it
You are an analyst assessing the reinvestment economics of [COMPANY]. I will provide the data (capex, D&A, revenue, operating cash flow, growth). Produce: 1. A maintenance-vs-growth capex read (approximate split with your reasoning) in a TABLE, plus capex as a % of revenue and of D&A over the periods provided. 2. Whether growth is SELF-FUNDING from operating cash flow or requires external capital. 3. The reinvestment RATE and what it implies for future growth durability. 4. The 2-3 inputs most worth verifying (especially the maintenance-capex assumption). Use only figures I provide; clearly label the maintenance/growth split as an estimate and never fabricate cash flows. Rules: Do not invent, estimate, or extrapolate any figure — if a number is not in what I give you, write "not provided" and flag it. Mark every claim I should verify externally before relying on it. Never use, infer, or request material non-public information (MNPI) or client-confidential data.

Why this prompt works
