What Is EBITDA and Should You Care About It?

Walk into any earnings call, investor presentation, or sell-side research report and you'll hear EBITDA mentioned more often than almost any other metric. Management teams love it. Bankers love it. Private equity firms practically live by it.

But if you listen carefully, you'll also notice that the investors most respected for long-term results — Buffett, Munger, and their intellectual descendants — tend to treat EBITDA with a skepticism that borders on contempt.

So what's going on? Is EBITDA useful or misleading? The honest answer is: it depends entirely on how it's used and whether you understand what it leaves out.

What Does EBITDA Stand For?

EBITDA stands for Earnings Before Interest, Taxes, Depreciation, and Amortization.

The formula starts with net income (or operating income) and adds back four items:

• Interest expense — the cost of servicing debt
• Taxes — income taxes paid to governments
• Depreciation — the accounting write-down of physical assets over time
• Amortization — the accounting write-down of intangible assets (like patents, trademarks, or acquired customer relationships) over time

EBITDA = Net Income + Interest + Taxes + Depreciation + Amortization

Or more simply, if you start from operating income (EBIT):

EBITDA = EBIT + Depreciation + Amortization

The resulting number is often described as a proxy for "operating profitability" — what the business earns before financing decisions and accounting conventions get involved.

Why Do Companies Love to Cite It?

EBITDA became popular for a few legitimate reasons — and a few less legitimate ones.

The legitimate reasons:

When comparing companies across different countries, different tax environments, or different capital structures, EBITDA removes noise that's not related to the underlying business operations. A highly leveraged company and a debt-free company doing the same underlying business will show very different net incomes. EBITDA strips out the financing differences so you can compare the operational engines.

It's also useful in leveraged buyouts (LBOs) — a key reason private equity firms use it. When a PE firm buys a company with mostly borrowed money, the interest expense is enormous and would make any net income figure meaningless. EBITDA tells you what the business earns before those debt costs, which is the relevant number when you're deciding how much debt a business can support.

EV/EBITDA (enterprise value divided by EBITDA) is a useful cross-sector multiple because it's capital-structure-neutral — you can use it to compare a debt-heavy telecom with a debt-free tech company in ways that P/E can't accommodate.

The less legitimate reason:

EBITDA is larger than net income. Always. Every company has a higher EBITDA than earnings, because you're adding things back rather than subtracting them.

This means EBITDA makes companies look more profitable than they are on a net basis — which is convenient for management teams pitching investors, bankers marketing deals, or companies trying to justify high acquisition prices. It's psychologically easier to say "we trade at 8× EBITDA" than to say "we trade at 30× earnings."

Warren Buffett's Famous Criticism

Warren Buffett has been consistently critical of EBITDA for decades, and his reasoning is worth understanding carefully.

At the 2002 Berkshire Hathaway annual meeting, Buffett said: "We won't buy into companies where someone's talking about EBITDA. If you look at all companies, and split them into companies that use EBITDA as a metric and those that don't, I suspect you'll find a lot more fraud in the former group."

That's a strong statement. What's behind it?

Charlie Munger was even more blunt, calling EBITDA "bullshit earnings."

Their core objection: depreciation is a real expense.

When a company buys a piece of equipment for $10 million, it doesn't expense the full $10 million immediately — it depreciates it over, say, 10 years, recording $1 million in depreciation expense per year. EBITDA adds that depreciation back, implying it's not a "real" cost.

But it is a real cost — paid in advance. The machine will wear out and need replacing. The infrastructure will degrade. The building will eventually need a new roof. Adding back depreciation assumes these asset replacements don't happen, which is false for any business that intends to keep operating.

As Buffett put it: "Does management think the tooth fairy pays for capital expenditures?"

A company that's reporting strong EBITDA while its assets quietly deteriorate is pulling forward profits that will eventually demand repayment in the form of catch-up capital expenditure. EBITDA hides this dynamic; free cash flow exposes it.

When EBITDA Is Legitimately Useful

Despite the criticism, there are real contexts where EBITDA earns its keep.

Early-stage or high-growth businesses with heavy initial capex. If a company is building out infrastructure that will last 20+ years, the depreciation on that infrastructure in early years is high — and arguably doesn't represent the ongoing "maintenance" cost of the business. EBITDA can help show the earnings power before this initial investment period ends.

Cross-company comparisons within capital-intensive sectors. When comparing cable companies, utilities, or telecoms, where capital structures and depreciation schedules vary widely, EV/EBITDA provides a more apples-to-apples comparison than P/E.

Credit analysis. When a lender wants to understand how much debt a business can safely carry, EBITDA (compared to interest expense or total debt) is a standard starting point — because it represents cash available before financing costs.

Normalized snapshots. Removing taxes and interest can highlight operating efficiency trends over time, independent of changes in capital structure.

The key is understanding what you're looking at. EBITDA is a tool for a specific job. The mistake is using it as a comprehensive picture of profitability.

When EBITDA Misleads

Businesses with continuous, high capex. For manufacturers, retailers with constant store refresh cycles, airlines, or any business where ongoing capital expenditure is just the cost of staying in business — EBITDA will chronically overstate true earnings. The depreciation is real, because the capex that caused it was real and will recur.

Companies using aggressive amortization policies. When companies acquire other businesses, the purchase price gets allocated to various intangible assets (customer relationships, trademarks, etc.) that are then amortized over several years. Adding back amortization to get EBITDA implies these acquired intangibles have no ongoing cost — but replacing them, if they decay, absolutely does.

"Adjusted EBITDA" madness. This is where things get truly slippery. Companies frequently report "Adjusted EBITDA" that strips out not just D&A, but also stock-based compensation, restructuring charges, acquisition costs, and other items labeled as "non-recurring." The problem: many of these charges recur every single year. Stock-based compensation is a real cost to shareholders — it dilutes ownership. Calling it "non-cash" doesn't make it free.

Some companies report Adjusted EBITDA figures that bear almost no relationship to the cash the business actually generates. When the gap between EBITDA and free cash flow is consistently large, that's a red flag worth investigating.

EBITDA vs. Free Cash Flow: The Better Question

If EBITDA is a rough approximation, free cash flow is the real thing.

Free cash flow — operating cash flow minus capital expenditures — tells you how much actual cash the business generated after maintaining and investing in its asset base. It doesn't add back depreciation (because capex, which generates the future depreciation, is already deducted). It doesn't ignore working capital changes. It reflects reality.

A company with strong EBITDA but weak or negative free cash flow is consuming cash somewhere — either in capex, in growing receivables, or in inventory buildup. That deserves scrutiny.

A company with EBITDA roughly equal to free cash flow is a strong sign that the business is genuinely as profitable as the headline number suggests.

At valueofstock.com, you can compare EBITDA-based multiples against free cash flow metrics to see how wide the gap is for any company you're analyzing — which is often one of the most telling signals in fundamental analysis.

A Framework for Using EBITDA Intelligently

Here's a practical approach:

1. Start with EBITDA as a rough operating profitability screen — useful for quick cross-company comparisons within the same sector.

2. Always check capex intensity. If capex/revenue is high (above 10–15% is significant for most businesses), treat EBITDA skeptically and focus on free cash flow.

3. Compare Adjusted EBITDA to reported EBITDA. The wider the gap, the more "adjusting" management is doing — and the more scrutiny the adjustments deserve.

4. Compare EBITDA to operating cash flow. If they're significantly different, understand why. Working capital buildups and real cash costs may be hiding in the gap.

5. Never use EBITDA alone to make a buy or sell decision. It's one data point, and a partial one at that.

The Bottom Line

EBITDA isn't inherently dishonest — it's a useful tool in specific contexts, particularly for comparing capital structures and evaluating debt capacity. The problem is that it gets misused as a substitute for actual profitability, which it isn't.

Buffett and Munger's skepticism is well-founded: depreciation represents real economic costs that businesses cannot escape indefinitely. A metric that pretends otherwise will systematically overstate how much money a business actually makes.

Use EBITDA as a starting point, not an endpoint. Always follow it with the question: how much of this flows through to actual free cash flow? If the answer is "most of it," the EBITDA picture is probably trustworthy. If the answer is "not much," you've found something worth digging into.

Real investors count real cash. Start there.
