Maintenance vs growth capex

Maintenance capital spending sustains existing operating capability; growth spending expands or improves future capacity. Projects may serve both purposes, so the split requires judgment.

Maintenance vs growth capex in round numbers

Hypothetical annual spending, in US$ millions: 2 of maintenance capex plus 1 of growth capex equals 3 of total capex in the same year. Actual free cash flow generally deducts all 3. A separately labeled maintenance-only owner-earnings estimate deducts 2 from a stated pre-capex starting measure, excluding the 1 of discretionary growth spending. Depreciation and amortization do not establish this cash-spending split.
