Question

What is the capex-as-maintenance indicator, and how do you use the capex / D&A ratio?

Answer

The capex / D&A ratio is a standard indicator of the investment cycle:

RatioInterpretation
= 1.0Steady state (maintenance capex ≈ D&A)
> 1.0Growth mode or catch-up needed
< 1.0Underinvestment, asset base shrinking
SectorCapex / D&A
Mature industrials1.0–1.3x
Growing tech0.5–1.0x (low PP&E base)
Telcos / utilities1.2–1.8x during investment phases (5G rollout, grid), 0.8–1.2x otherwise
Capital-intensive manufacturing (automotive, steel)1.0–1.5x

  • Valuation plausibility: If a target shows capex / D&A < 0.8 for 3+ years, the valuation should build a capex catch-up into the forecast — otherwise it is too optimistic.
  • PE acquisition logic: Underinvestment targets offer value creation through capex restoration; clearing deferred maintenance reduces operating risk.

'The target shows capex / D&A of 0.7 over the last 3 years — the valuation is adjusted for $30m of catch-up capex over years 1–3, reducing PV by $25m'.
