What Is EBITDA and Why Does Every Investor and Banker Obsess Over It?
EBITDA strips out financing, tax and accounting decisions to show what a business actually earns from operations. It is also one of the most abused metrics in corporate finance.
EBITDA appears in almost every corporate earnings call, investor presentation and M&A transaction. It is also misunderstood, routinely manipulated, and used to paint companies in a flattering light that bears little resemblance to their actual cash generation. Let me explain both why it matters and why you should always look behind it.
What EBITDA Stands For
Earnings Before Interest, Taxes, Depreciation and Amortisation. To calculate it: start with operating profit (EBIT), then add back depreciation and amortisation. Or start with net profit and add back interest expense, tax charge, depreciation and amortisation.
The purpose is to strip out variables that relate to financing decisions (interest), jurisdiction (tax), and accounting treatment of past capital expenditure (D&A) — leaving a number that reflects the underlying operational performance of the business regardless of its capital structure or accounting policy choices.
Why Bankers Love It
When an investment bank values a company for acquisition, the most common methodology is EV/EBITDA multiples — enterprise value divided by EBITDA. A manufacturing business might trade at 7-8x EBITDA. A SaaS business at 15-25x. The multiple reflects growth expectations, margin quality, and market comparables.
EBITDA allows apples-to-apples comparison between companies with different debt levels. Company A might have net profit of zero because it carries heavy acquisition debt. Company B might show strong net profit because it is equity-financed. Their operational performance could be identical — EBITDA reveals that; net profit obscures it.
Why You Should Always Look Behind It
EBITDA is not cash flow. A company can have £50m EBITDA and be burning cash if it requires heavy working capital investment or high capital expenditure to maintain its infrastructure. The gap between EBITDA and free cash flow is where frauds hide and where optimistic projections collapse.
Adjusted EBITDA — where companies add back one-off costs, restructuring charges and share-based compensation — is particularly treacherous. When a company's "one-off" charges appear in every year's results, they are not one-off. Always reconcile adjusted EBITDA to statutory EBITDA and then to operating cash flow.
Key Takeaways
- EBITDA shows operational earnings before financing, tax and non-cash charges — useful for comparing companies with different capital structures
- EBITDA is not cash flow — always check the gap between EBITDA and free cash flow
- EV/EBITDA multiples are the primary valuation methodology in M&A — sector averages vary from 6x (manufacturing) to 20x+ (software)
- Be sceptical of "adjusted EBITDA" that adds back items appearing every year — these are operating costs, not one-offs
