Beyond the EBITDA Delusion: Why "Owner Earnings" and Free Cash Flow Yield are the True North of Your Investment

Key Takeaways

In the modern world of private equity and business acquisitions, "EBITDA" (Earnings Before Interest, Taxes, Depreciation, and Amortization) has become the undisputed lingua franca. It is the metric that graces every teaser, every Confidential Information Memorandum (CIM), and nearly every Letter of Intent (LOI) in the Lower Middle Market (LMM). We talk about "four-times EBITDA" or "six-times EBITDA" as if we are discussing a universal law of physics. However, for the sophisticated investor and the prudent business operator, leaning too heavily on EBITDA is not just a tactical error—it is a fundamental misunderstanding of how wealth is actually created and how capital is truly recouped.

The hard truth is that EBITDA does not represent the cash that a business can actually provide to its owners. It is a proxy for operating performance, but it is a "leaky" proxy. In capital-intensive industries—heavy equipment, manufacturing, or high-inventory retail—the gap between EBITDA and actual spendable cash can be a canyon that swallows entire investment theses. If you buy a business based on an EBITDA multiple without accounting for the actual cash costs of maintenance and reinvestment, you may think you are buying a 3x bargain, only to realize you’ve tethered yourself to a 15x anchor. This article explores the history of EBITDA, the genius of Warren Buffett’s "Owner Earnings," and why matching your financial tools to your specific investment strategy is the only way to ensure your capital actually returns home.

Part 1: The John Malone Legacy (A Tool Built for a Specific Job)

To understand why we use EBITDA today, we must understand why it was invented in the first place. It wasn't designed as a general-purpose valuation tool for small businesses; it was a specialized weapon forged by John Malone, the legendary "Cable Cowboy" of TCI. Malone was operating in an industry—cable television—that required massive upfront capital expenditures to lay down infrastructure. Under standard accounting (Net Income), his company looked like a perennial loser because the heavy depreciation of those cables wiped out his reported profits.

The Malone Strategy: Growth Through Deferral

Malone needed a way to convince banks and investors that his business was incredibly healthy despite having no Net Income. He pioneered the use of EBITDA to show the "operating power" of the business before the government and the accounting rules took their cut.

The Goal: Malone’s strategy was built on "Creative M&A" and massive consolidation. He used the cash flow (EBITDA) to service huge amounts of debt to buy more companies, which created more depreciation, which meant he paid virtually zero taxes for decades.
The Context: Malone wasn't a "Buy and Hold" investor in the traditional sense; he was a "Buy and Build" engineer. He used EBITDA to justify leverage for a strategy of aggressive redeployment. He was turning operating profit back into growth assets as fast as humanly possible.

The Mismatch: Using the Wrong Tool for the Job

The problem in the LMM today is that many investors use Malone’s tool (EBITDA) for a completely different job. If you are a "Buy and Hold" investor or an independent sponsor looking for stable cash yield, EBITDA is often irrelevant. If you aren't planning a massive roll-up or a tax-deferred growth spiral, using EBITDA is like trying to drive a nail with a screwdriver. You are using a metric designed for aggressive financial engineering on a business that requires simple, honest cash flow. Unless there is a very tight, near-identical relationship between EBITDA and what the owner can actually take home, the metric is lying to you about your actual returns.

Part 2: The EBITDA Trap (When 3x is Actually 15x)

The most dangerous part of the EBITDA delusion is that it masks the "re-investment" requirement of a business. When you look at an EBITDA number, the "D" (Depreciation) and "A" (Amortization) are added back to the profit. This implies that those costs aren't "real" because they aren't cash leaving the bank this month. But in the real world, things wear out. Trucks break down, software becomes obsolete, and roofs leak.

Maintenance CapEx: The Silent Profit Killer

For a capital-intensive business, a large portion of EBITDA must be immediately redeployed into Maintenance CapEx—the money required just to keep the business exactly where it is today.

The Math of the Trap:

Imagine you buy a heavy equipment manufacturer for $3 million. The business does $1 million in EBITDA. On paper, you paid a 3x multiple. You expect your capital to be returned in 3 years.

The Reality:

Every year, you have to spend $800,000 replacing old lathes and CNC machines just to keep production running. Your actual "Free Cash Flow" is only $200,000.

The Result: Instead of a 3-year payback, you are now looking at a 15-year payback ($3M / $200k). You didn't buy a 3x business; you bought a 15x business. If you had known that up front, you would have demanded a far lower price or significantly different terms.

Service vs. Product: The Complexity of the Relationship

Service-based businesses—like digital agencies or consulting firms—often have a much tighter relationship between EBITDA and Cash Flow because they have few "hard assets" to replace. In those cases, EBITDA is a "safer" (though still imperfect) metric. But the moment you step into "Product" or "Heavy Equipment" territory, the relationship breaks. You must think like an owner, not an accountant. You must ask: "After I pay for the privilege of staying in business, how much is actually left for me to put in my pocket?"

Part 3: Warren Buffett’s "Owner Earnings" (The Ultimate Truth)

While the rest of the world was falling in love with EBITDA in the 1980s, Warren Buffett was warning against it. He famously called EBITDA "Short-hand for 'Earnings before the stuff that matters.'" He realized that the "add-backs" in EBITDA were often deceptive. In his 1986 letter to Berkshire Hathaway shareholders, he defined a metric that every LMM investor and operator should memorize: Owner Earnings.

How Buffett Calculates the Truth

Buffett’s calculation of Owner Earnings is the "True North" for any investor who actually wants to understand the economic reality of a business. It’s not about being fancy; it’s about being honest about costs.

$$Owner Earnings = Reported Earnings + (Depreciation + Amortization) - (Average Annual Capital Expenditures)$$

The Key Insight: Buffett’s formula explicitly subtracts the "Maintenance CapEx." He recognized that if a business requires $1 million in equipment upgrades every year to maintain its competitive position, that $1 million is not "earnings"—it is an unavoidable cost of staying alive.

Why it matters for LMM: When Buffett was starting out, he wasn't buying giant conglomerates; he was buying "Lower Middle Market" companies like See’s Candies. He looked for companies where the "Capital Expenditure" requirement was low compared to the profits. He wanted "Asset-Light" cash engines where the EBITDA and the Owner Earnings were nearly the same.

Recouping Capital: The "Lending to a Friend" Connection

Everything in investing comes back to the framework we discussed in Article 14: How long until my capital is returned? The time frame to have your capital returned is a key contributor to the likelihood that it will be returned at all.

If you use EBITDA, you might think your capital is coming home in 3 years.
If you use Owner Earnings, you might realize it’s actually coming home in 10 years.

That gap represents a massive increase in risk. The longer your money is "out in the field," the more chances there are for a competitor, a recession, or a "volatile event" to happen. If you find a business where Owner Earnings are significantly lower than EBITDA, you aren't looking at a bargain; you are looking at a long-term risk.

Part 4: Free Cash Flow Yield (The Operator's Scorecard)

If EBITDA is a theoretical "potential," then Free Cash Flow Yield is the "actual result." This is a term that sophisticated investors use to see how much "yield" or cash-on-cash return a business actually provides relative to its price.

What is FCF Yield?

Simply put, it’s the Free Cash Flow (or Owner Earnings) divided by the Enterprise Value (or Purchase Price).

High FCF Yield: Means the business is spitting out a lot of cash relative to its cost. This is the hallmark of a healthy, "Blue Chip" LMM asset.
Low FCF Yield: Means the business might have a "shiny" EBITDA number, but it’s eating all its own cash to survive.

The Cash Conversion Cycle (The Timing Disconnect)

Another reason EBITDA lies is because of the Cash Conversion Cycle (Article 5). Revenue is an accounting event; Cash is a bank event. If you recognize revenue today but don't collect the cash for 120 days, your EBITDA looks great, but your "Owner Earnings" are non-existent for that period.

The Relationship: If revenue and cash are flowing at different time frames, your "Cash Conversion Rate" (how much EBITDA becomes Cash) will be low. The Risk: A complicated relationship between EBITDA and cash flow makes it much less likely that your assumptions about capital return will be realized. You might be "profitable" on paper while being "broke" at the bank.

Part 5: Thinking Like a Lender (Creditworthiness is an Equity Metric)

There is a common misconception that "Creditworthiness" is only something a bank cares about. But as an equity investor—the person who owns the business—you must think exactly like a lender. You are essentially "lending" your capital to the company in exchange for a claim on its future earnings.

The Factors of Repayment

Lenders look at the "likelihood" of repayment. They ask:

The Stability of the Stream: Is the income stream (the "job") stable? Does it fluctuate or vanish for erratic reasons?
The Margin of Safety: How much can the business drop before it can't pay the owner?
The Asset Base: What is actually left if the "earnings" stop?

Why Equity Investors Need "Credit" Thinking

If the "Owner Earnings" of a business are low because all the cash is being redeployed into maintenance, the business has poor creditworthiness from your perspective as the owner. It doesn't matter if the EBITDA is high; if that money isn't "attributable to the owner," your capital is going to take longer to come back.

As the time frame for return expands, the likelihood of return diminishes. By using an inappropriate metric (EBITDA) for a business that isn't turning that profit into cash, you are ignoring the creditworthiness of your own investment. You are taking a "Junior" risk for a "Senior" return.

Part 6: The "Buy and Hold" Mismatch

John Malone used EBITDA for a specific growth strategy Layered with M&A. If you aren't doing that, you shouldn't use his tool. For a "Buy and Hold" type investment—where the goal is long-term stability and cash yield—EBITDA is often a distraction.

The "Creative M&A" Exception

EBITDA is relevant if you are doing a "Roll-up" or a consolidation strategy. Why? Because you are purposefully not paying taxes and you are purposefully redeploying every dollar to grow the enterprise value for a massive, single exit down the road. You are playing the "Financial Engineering" game.

The "Owner's Reality" Strategy

However, if your goal is to have a business that provides for your family and builds wealth through steady dividends, you must use Net Income with an adjustment for Free Cash Flow.

You want a business where the gap between EBITDA and Owner Earnings is small.
You want to look at the Cash Yield—exactly how much cash you can pull out every year without hurting the business.

If you aren't planning to be John Malone, don't use John Malone's metrics. Use Buffett’s. Use the tools that reflect the reality of your bank account, not a banker's debt model.

Part 7: How to Identify "Cash-Heavy" Businesses

When you are looking at potential acquisitions (or evaluating your own company), you want to find indicators that the EBITDA will actually become cash. Here are a few "under-the-hood" signals to look for:

Low Maintenance CapEx as a % of Revenue: If the business only needs to spend 1-2% of its revenue on new equipment, it is a "Cash Cow."
Negative Working Capital: This is the "Holy Grail." It means customers pay you before you have to pay your suppliers (like Amazon). In these businesses, Free Cash Flow is often higher than EBITDA.
High Cash Conversion Rate: Simply divide your Free Cash Flow by your EBITDA. If the number is above 80%, you are in a high-quality asset. If it’s below 40%, you are in a "Maintenance Trap."

The Pricing Correction

The multiple you pay on EBITDA should be a direct reflection of these cash dynamics.

Business A: $1M EBITDA, 90% Cash Conversion. (Pay a high multiple).
Business B: $1M EBITDA, 20% Cash Conversion. (Pay a very low multiple).

If you pay the same multiple for both because "the industry average is 5x," you have failed as an underwriter. You have ignored the physics of the investment in favor of the folklore of the market.

Part 8: The "Owner Earnings" Audit (A Step-by-Step Guide)

To truly "button up" your underwriting, you must perform an "Owner Earnings Audit" before signing any deal. This moves the conversation from the broker's "Adjusted EBITDA" to the reality of the cash register.

Step 1: The Maintenance Investigation

Look at the list of heavy equipment. Ask for the age of every machine. Compare the "Book Depreciation" (the accounting number) to the actual cost of a new machine today. Often, a machine bought for $100k ten years ago costs $250k to replace today. The "D" in EBITDA is lying to you about the true cost of replacement.

Step 2: The Working Capital "Suck"

Model out what happens if the business grows. If you grow revenue by $1M, how much of that is "trapped" in inventory and receivables? That "trapped" cash isn't yours to spend; it’s the "gas" the business needs to move forward. In a high-growth LMM company, this can often consume the entire profit.

Step 3: The Tax Normalization

EBITDA is "Before Taxes," but owners live "After Taxes." If you aren't doing Malone-style M&A to defer taxes, you need to look at your After-Tax Free Cash Flow. This is the only money that can actually return your initial capital.

Step 4: The Final Yield Test

Take your After-Tax Free Cash Flow and divide it by your total cash investment (the down payment + closing costs). This is your Actual Cash Yield.

Is it 20%? (You'll get your money back in 5 years).
Is it 5%? (You'll get your money back in 20 years).

If the time frame is 20 years, the likelihood of a "volatile event" destroying your investment is nearly 100%. You must adjust your price until the Yield reflects a safe time frame for capital return.

Part 9: Why Time Frame is the Only Metric

At the end of the day, everything in investing comes back to this one question: How long will it take for my capital to be returned? The time frame is the ultimate proxy for risk.

Short Time Frame: You are lending money to a friend who is paying you back tomorrow (Article 14). It is safe, predictable, and "underwritable."
Long Time Frame: You are lending money for 30 years. It is speculative and dangerous.

EBITDA is a "fuzzy" metric that often hides the true time frame. By ignoring the CapEx, ignoring the taxes, and ignoring the working capital, it makes the time frame look shorter than it is. This lures investors into taking risks they don't understand. Sophisticated investors—and the sellers who want to maximize their value—focus on Owner Earnings because it provides an honest answer to the "Time" question.

Part 10: Advice for Sellers (The Value of a Clean Cash Stream)

If you are a seller, your goal is to make the relationship between your EBITDA and your cash flow as "tight" as possible. You want to show the buyer that you have a "Cash Machine," not a "Maintenance Nightmare."

How to Maximize Your Value:

Clean up the CapEx: Don't defer maintenance for three years before a sale. A buyer will see the old equipment and "adjust" your price downward by more than the cost of the repair.
Optimize Working Capital: Collect your receivables faster. Pay your vendors on time, but don't pay them 30 days early if you don't have to.
Use "Owner Earnings" in your own reporting: If you can show a buyer a five-year history where 90% of your EBITDA became spendable cash, you will command a premium multiple that your competitors can't touch. You are selling Certainty, and Certainty is the most valuable commodity in the Lower Middle Market.

Conclusion: Don't Fall for the Illusion

EBITDA is a useful term for a cable tycoon in the 1970s, but it can be a dangerous illusion for a private equity investor in 2026. It is a metric designed to support leverage and growth-at-all-costs, but it was never intended to measure the actual wealth a business provides to its owner.

As an operator, your goal is to build a business with a high Free Cash Flow Yield. As an investor, your goal is to find one. Stop leaning on the broker's EBITDA multiple and start looking at the "Owner's Reality."

Does the business have a "job" that provides stable cash?
Is the "Creditworthiness" of the business high enough to ensure a return?
How long is the "time frame" until your initial capital is back in your hand?

Match the tool to your strategy. If you're a buy-and-hold investor, look at Owner Earnings. Respect the physics of cash, calculate your yield accurately, and never forget that in the LMM, cash isn't just a number on a spreadsheet—it's the only thing that proves your investment was a success. Price the business based on the cash you can take home, not the profit you have to put back in.
