Simple definition

Money spent on buying or upgrading factories, equipment, land, and other long-term assets — the investment to sustain and grow the business.

🗣️

"Capex matlab company ne naye factories, machines, ya equipment mein kitna paisa lagaya. Yeh future growth ke liye invest kiya jaata hai."

Why it matters

  1. FCF driver — FCF = CFO − Capex. High capex reduces free cash flow available to shareholders
  2. Growth signal — increasing capex often means the company is investing in capacity expansion
  3. Future depreciation — today's capex becomes tomorrow's depreciation expense
  4. Maintenance vs Growth — understanding the split reveals true growth investment

Formula

Capex = Purchase of PPE + Purchase of Intangible Assets

Found in the Cash Flow Statement under "Investing Activities."

Types of capex

Type Purpose Example
Maintenance capex Replace old/worn-out assets Replacing old machinery
Growth capex Expand capacity or enter new markets New factory, new product line
Regulatory capex Meet compliance/environment norms Pollution control equipment

Maintenance vs Growth split

Companies rarely disclose this split. A rough estimate: Maintenance capex ≈ Depreciation. Capex above depreciation is likely growth capex.

Capex intensity — by sector

Sector Capex as % of Revenue Classification
IT Services 3–6% Very light
FMCG 4–8% Light
Pharma 5–10% Moderate
Auto (OEM) 8–15% Moderate-heavy
Steel/Cement 10–20% Heavy
Telecom 25–40% Very heavy
Oil & Gas 20–30% Very heavy

Capex cycle

Announce capex plan
Spend capex (2-3 years)
Capacity comes online
Revenue ramp-up
ROCE improves
FCF recovers

During the capex phase, FCF drops and ROCE may fall. This is normal. The key question: will the new capacity generate adequate returns?

Common mistakes

Mistakes to avoid

  1. Capex = bad — Wrong. Capex is investment for future growth. No capex means no growth
  2. Ignoring CWIP — Capital Work in Progress shows how much capex is ongoing but not yet completed
  3. Not comparing capex to CFO — If capex > CFO for many years, the difference is funded by debt
  4. Lumpy vs smooth capex — Some companies do capex in large lumps every 3–5 years. Don't compare a capex year with a non-capex year

Real example: Light vs Heavy capex

Company Revenue (₹ Cr) Capex (₹ Cr) Capex/Rev CFO (₹ Cr) FCF
Infosys 1,50,000 5,000 3.3% 28,000 23,000
JSW Steel 1,70,000 20,000 11.8% 25,000 5,000
Bharti Airtel 1,50,000 35,000 23.3% 55,000 20,000

Infosys spends very little on capex → almost all CFO becomes FCF. JSW Steel and Airtel need massive capex to stay competitive, consuming most of their CFO.

Red flags

  • Capex > CFO for 3+ consecutive years — funding capex with debt
  • Large capex without corresponding revenue growth in 2–3 years — potential value destruction
  • Capex cuts when competition is investing — may lose market share
  • CWIP growing without projects completing — possible project delays or cost overruns
