EBIT versus EBITDA
What adding D&A back does
Depreciation and amortization are allocations. No cash moves when they hit the income statement. A company that bought its plant ten years ago and a competitor that bought an identical plant last year will report very different depreciation against the same operations. Useful-life and salvage assumptions vary by management too, and so does the mix of purchased versus leased assets.
Adding D&A back takes those choices out of the comparison. That's why EBITDA travels well across a comp set with mixed asset ages, and why it's the number credit investors usually start from when they size how much debt a business can carry.
What it doesn't tell you
Adding D&A back has no effect on the assets themselves. The engines still wear out, the servers still get replaced, and the cash for the replacement leaves the company on the capex line. D&A is the accountant's estimate of that cost, spread across the years the asset works. Take it out of the income statement and the spending still happens, it just shows up somewhere the metric can't see it.
EBITDA also sits above working capital, cash taxes, and interest. Plenty of businesses report healthy EBITDA and generate no free cash flow at all, usually because growth eats the cash in receivables and inventory before it ever reaches the owner.
Capital intensity is the deciding factor
The distance between EBIT and EBITDA is exactly the size of D&A, so the real question is how much of the earnings depends on assets the company has to buy again.
Take a rocket company that owns its factories, test stands, and launch infrastructure. D&A is large, maintenance capex is real and recurring, and EBITDA flatters the business by treating an unavoidable category of spending as if it were optional. In software or staffing, D&A is small, the two numbers sit close together, and the choice barely moves the valuation.
The working test is whether maintenance capex runs close to D&A. When it does, EBIT is the better stand-in for what the operations earn after keeping the asset base intact, and quoting EBITDA in a capital-heavy business is how you end up defending a number the company can never distribute.
Where EBITDA has the better argument
Purchase accounting. When a buyer allocates purchase price, part of it lands on finite-lived intangibles such as customer relationships, developed technology, and trade names, and those amortize through the income statement for years afterward. Goodwill under US GAAP is tested for impairment instead of being amortized, but the rest of that intangible balance runs straight through operating expenses.
So a company that grew by acquisition carries an amortization charge that a competitor who built the same business in-house never reports. The cash for those intangibles went out once, at closing. The amortization is the accounting tail. For a serial acquirer, EBIT understates operating performance, and EBITDA (or EBITA, which strips only the amortization) puts the two companies back on the same footing.
How it shows up in the multiple
Both metrics pair with Enterprise Value, since EV, EBIT, and EBITDA are all capital-structure neutral. EV/EBITDA is the default screen in most sectors. EV/EBIT is the cross-check, and it matters most when the comp set mixes capital intensities: on EV/EBITDA the asset-heavy company looks cheap against the asset-light one, and EV/EBIT closes part of that gap by charging the heavy company for the assets it consumes.
If you quote one, know what the other says. A stock that looks cheap on EV/EBITDA and expensive on EV/EBIT is usually telling you the depreciation is real.
Interview script
EBIT, or Earnings Before Interest and Taxes, measures a company's operating profitability independent of its capital structure and tax jurisdiction. We use it heavily in M&A and LBO analysis because when you're acquiring a business, you don't care about the seller's existing debt or interest expense. You're replacing their capital structure with your own. It tells you what the core operations actually produce before financing and tax decisions.
If they follow up with why not just use EBITDA: EBITDA adds back depreciation and amortization, which is useful when you're comparing companies with different asset ages or different depreciation policies, and it's closer to what lenders underwrite against. The cost is that it treats the spending required to keep the asset base intact as though it were optional. In a capital-intensive business where maintenance capex runs close to D&A, EBIT is the more honest read on what the operations earn. In an asset-light business the two converge. The main exception runs the other way: for a serial acquirer, EBIT carries amortization of acquired intangibles, so it understates what the business really produces.
