How important is cash flow compared with EBITDA when valuing a company?

Looking beneath the surface of EBITDA.

In corporate finance, EBITDA has become the shorthand for operating performance. However, it remains an intermediate metric. It indicates gross operating profitability but fundamentally fails to capture the actual financial resources available to the owners.

A robust valuation must look beyond this proxy. Two companies reporting an identical EBITDA of five million can face opposite strategic futures if one seamlessly converts that margin into bank cash, while the other entirely absorbs it in inventory, equipment and extended customer credit.

The drain of working capital.

The first major divergence between accounting margins and tangible cash lies in operating working capital. Growth is expensive: increasing revenues typically necessitates holding more inventory and financing longer payment terms for customers.

If the working capital cycle is inefficient, the company acts as a sponge, consuming liquidity in direct proportion to its growth. Investors rigorously test this dynamic, as excessive working capital absorption severely depresses the return on invested capital.

Capital Expenditure (CAPEX) requirements.

EBITDA is calculated before depreciation, effectively ignoring the cost of fixed assets. Yet, to remain competitive and sustain expansion, businesses must continuously invest in technology, machinery and infrastructure (Capital Expenditure).

Operating cash flow, calculated after deducting CAPEX, reveals the true economic engine of the business. A highly capital-intensive model will systematically yield lower free cash flows relative to the theoretical margins suggested by its EBITDA.

Cash conversion also needs to be read across the operating calendar rather than from a single year-end balance. In a seasonal business, inventory accumulated before the sales peak and receivables collected afterwards may create very different funding needs during the year. A snapshot taken in the most favourable month can therefore understate the capital required to trade. Billing schedules, customer deposits, supplier terms and production peaks help explain volatility that EBITDA does not capture. Capital expenditure requires a parallel distinction. Maintenance CAPEX preserves existing capacity, safety and service quality; growth CAPEX adds capacity, automation or new sites. The classification is most informative when supported by project records, asset histories and identifiable incremental output, because an unavoidable replacement labelled as growth would overstate cash available for other uses. Reviewing several years alongside the renewal cycle of major assets helps distinguish a temporary period of low spending from durable self-funding capacity and makes comparisons between companies with different asset ages more meaningful.

The burden of debt and taxation.

Financial obligations, including debt service and corporate taxes, drastically reduce the final cash available to shareholders. A company burdened by expensive debt must allocate a substantial portion of its operating margin to principal and interest repayments, thereby constricting strategic flexibility.

These outflows, while invisible at the EBITDA level, define the absolute boundaries of corporate liquidity. It is the Free Cash Flow to Equity—cash remaining after debt service—that dictates dividend capacity or the ability to fund acquisitions.

Cash conversion as the essential indicator.

The Cash Conversion Ratio (operating cash flow divided by EBITDA) serves as an essential indicator of earnings quality. A high conversion rate implies strong pricing power, lean operations and minimal tied-up capital.

Conversely, a persistent divergence between rising accounting profits and weak cash generation raises immediate red flags regarding the collectability of receivables or obsolete inventory, inevitably influencing institutional valuation estimates.

Implications for Value Creation.

Private equity funds structure their investments—particularly leveraged buyouts—based on cash capacity, not EBITDA. The debt raised to finance a transaction can only be serviced if the target company generates predictable, sufficient liquid cash flows.

Consequently, entering negotiations focused solely on EBITDA exposes the entrepreneur to a sharp downward revision of expectations once the investor applies their models to net cash generation and actual spending requirements.

Investment Readiness and financial discipline.

Shifting management's focus from EBITDA to cash flow is a cornerstone of Investment Readiness. It necessitates implementing reporting systems that track divisional cash generation, setting treasury KPIs, and aligning executive incentives with liquid results.

A company that proactively governs its financial dynamics presents institutional partners with a high degree of reliability. This discipline reduces the risk that unforeseen operational inefficiencies complicate the business plan.
