Free cash flow (FCF) is EBITDA minus capital expenditure, adjusted for working capital movements. It represents cash available after funding the investment required to maintain and grow operating capability. Unlike EBITDA — which is calculated before capex — FCF reflects the true cash economics of the business. A business with $5M EBITDA and $2M of annual maintenance capex has a FCF of approximately $3M at full working capital efficiency.
How each stakeholder reads it
Free Cash Flow looks different depending on your role.
FCF is the cash you actually have. EBITDA tells you what you earned. FCF tells you what you kept after paying for the assets required to keep the business running. In capital-light services, FCF and EBITDA may be close. In manufacturing and industrial businesses with significant equipment and infrastructure, the gap is often material — and consistently surprising to founders who manage primarily to the P&L.
FCF is central to our portfolio financial model. EBITDA is the valuation entry point, but FCF funds debt repayment, bolt-on acquisitions and distributions. Capital-intensive businesses with low FCF conversion require more equity to deliver returns, reducing capital efficiency. In industrial acquisitions, improving FCF conversion through working capital efficiency is consistently one of the most capital-efficient value creation programs available.
FCF optimisation requires active management of all three components: EBITDA improvement, working capital efficiency and capex discipline. The operator who improves FCF conversion — without reducing revenue — creates capacity for growth, debt repayment and value distribution that EBITDA improvement alone does not generate.
FCF is the board metric that determines strategic capacity. A business generating strong EBITDA but poor FCF — due to high capex or working capital consumption — has limited capacity for investment, acquisition or distribution. The board should understand the FCF conversion rate and the drivers of any EBITDA-to-FCF gap.
Why it matters
FCF determines whether growth is self-funding or capital-consuming.
High FCF conversion means growth funds itself. Low FCF conversion means growth consumes cash. The distinction determines the equity and debt required to support the operating plan — and whether the business can grow organically or requires external capital to fund expansion.
FCF conversion also influences PE valuation. Sophisticated buyers evaluate capital-intensive businesses on an EV/FCF basis — not just EV/EBITDA — because FCF more accurately reflects the cash economics. A business demonstrating improving FCF conversion commands a valuation premium from FCF-focused buyers.
Operational context
What shapes free cash flow inside a business.
Common failure patterns
- Maintenance capex chronically deferred — reducing near-term FCF while building future catch-up capex risk
- Working capital growth outpacing revenue — indicating commercial discipline deterioration rather than healthy expansion
- Growth capex approved without FCF return modelling — capital deployed without clarity on cash payback

Free Cash Flow
Is What EBITDA Becomes After the Business Pays Its Own Bills
EBITDA tells you what you earned. Free cash flow tells you what you kept. Understanding the gap — and closing it — creates the financial capacity that EBITDA alone cannot.
