EBITDA and 'Adjusted' Earnings

By now you can read a P&L down to net profit. But in earnings reports and investor decks, you’ll rarely see leaders dwell on that bottom line. Instead they reach for EBITDA and a family of “adjusted” numbers. These aren’t fake — they’re genuinely useful — but they’re also the most flattering way to present results, so understanding them (and their tricks) is a core skill for reading the real story. We’ll use Foundry Manufacturing, the precision-metal-parts maker we’ve been following, to see exactly how flattering they can be.

What EBITDA is

EBITDA stands for Earnings Before Interest, Taxes, Depreciation, and Amortization. It’s a profit measure that deliberately adds back four things to show the raw earning power of core operations:

• Interest — the cost of the company’s debt (a financing choice, not an operating one).
• Taxes — vary by location and structure.
• Depreciation — the non-cash charge spreading the cost of physical assets over their life.
• Amortization — the same idea for intangible assets like software or patents.

Strip those out and you get a rough proxy for the cash the operations throw off, before financing and accounting effects. The logic: it lets you compare two businesses’ operations even if one carries lots of debt and the other doesn’t.

Foundry makes this concrete. Its bottom-line net profit is $600,000. To rebuild EBITDA you add back the four items in turn: +$200,000 of tax, +$200,000 of interest, and +$800,000 of depreciation and amortization. That’s $0.6M + $0.2M + $0.2M + $0.8M = EBITDA of $1.8M — three times the net figure, from the very same business.

Why it flatters

Here’s the catch. Because EBITDA ignores depreciation, it quietly pretends the wear-and-tear on expensive equipment isn’t a real cost. Foundry runs a factory floor of presses and machining lines carried at $5M net — that’s why its D&A is a hefty $800,000 a year, and the money to replace those machines is very real. And because it ignores interest, the $200,000 cost of Foundry’s $3M bank loan simply vanishes from the headline.

That’s why the $1.2M gap between Foundry’s EBITDA ($1.8M) and its net income ($600k) is worth a question: what’s living in that gap? For Foundry it’s exactly the D&A, interest, and tax — the costs of being a capital-heavy, debt-carrying manufacturer. EBITDA is genuinely useful for comparing Foundry’s operations against a rival’s, but a company drowning in debt or equipment can show a healthy EBITDA while its actual net income is thin or negative.

The “adjusted” game

Companies also report adjusted figures — “adjusted EBITDA,” “adjusted earnings,” “non-GAAP” results — where they add back extra items they argue are one-off or non-representative: restructuring costs, legal settlements, and (controversially) stock-based compensation. Sometimes these adjustments are fair. Sometimes they’re a way to make a rough quarter look smooth. The warning sign is a company that every single quarter has large “one-time” adjustments — if it happens every time, it isn’t one-time.

Remember: the more a company leans on adjusted numbers while its official (GAAP) net income stays weak, the more skeptical you should be. Adjustments should be the exception it explains, not the number it leads with.

How to use it

EBITDA is a genuinely useful tool for comparing operations — just never let it be the only number you look at. When someone quotes it, ask the two questions that cut through: “How does that compare to actual net income?” and “What’s being adjusted out, and does it happen every quarter?” With Foundry, the honest answer is that the $1.8M EBITDA becomes $0.6M of net profit once the factory’s depreciation, loan interest and tax are paid — a real business can explain that gap and keeps its adjustments rare and specific. A shakier one leads with adjusted EBITDA precisely because the real bottom line is less flattering. For the article version of this, see EBITDA vs Net Income and EBITDA Meaning.
