# EV/EBITDA

EV/EBITDA is a valuation multiple that divides a company's enterprise value by its earnings before interest, taxes, depreciation, and amortization, showing how its total business value compares with that earnings measure.

## What it means

EV/EBITDA compares the value of an entire business with a measure of its operating earnings. Unlike a share-price multiple, it starts with enterprise value (EV), which accounts for both equity and debt financing. EBITDA means earnings before interest, taxes, depreciation, and amortization.

The result is a multiple, usually written as “8×” rather than a percentage. It can help compare businesses with different debt levels, but it does not establish what a stock is worth on its own. The reporting period, accounting choices, business model, and financial condition all affect interpretation.

## How it is calculated

`EV/EBITDA = enterprise value ÷ EBITDA`

- **Enterprise value (EV):** A commonly used simplified calculation is `market capitalization + total debt − cash and cash equivalents`. Market capitalization is share price multiplied by shares outstanding. More detailed EV calculations may include preferred equity and noncontrolling interests where applicable.
- **EBITDA:** Earnings before interest, taxes, depreciation, and amortization for a stated period, often the last 12 months. One common calculation is `net income + interest expense + income tax expense + depreciation + amortization`, using consistent financial statements.

EV and EBITDA must use the same currency. EV is a value at a point in time; EBITDA covers a period. Dividing one by the other produces a multiple: the figure is dimensionless, not a return rate or a number of years guaranteed to recover an investment. State whether EBITDA is historical or a forecast, because changing the period changes the ratio.

## Worked example

All figures below are hypothetical and in US$.

1. A company has a market capitalization of **US$800 million**, total debt of **US$300 million**, and cash and cash equivalents of **US$100 million**.
2. Using the simplified formula, EV is **US$800 million + US$300 million − US$100 million = US$1 billion**.
3. Its EBITDA for the last 12 months is **US$125 million**.
4. EV/EBITDA is **US$1 billion ÷ US$125 million = 8×**.

That means the calculated enterprise value is eight times the stated annual EBITDA. It does **not** mean an investor will earn an eightfold return, or that the business will repay its purchase price in eight years. Debt costs, taxes, capital spending, and changes in earnings still matter.

## Why it matters before you trade

EV/EBITDA is one input to fundamental analysis: it puts a company's market value and financing obligations beside an earnings measure. Comparing multiples may be more informative when companies have similar operations, accounting practices, and growth and capital-spending needs. A lower multiple is not automatically a bargain; it may reflect weaker prospects or greater risk.

A pre-trade check addresses a different question. Even if a valuation looks reasonable to an investor, a stock's liquidity, spread, order size, and potential market impact can affect the cost and risk of entering or exiting a position. Valuation and execution risk should not be confused.

## How PreTrAIde uses it

PreTrAIde's stated product facts do not identify EV/EBITDA as a calculated field or a direct input to its verdicts. Its pre-trade analysis examines a proposed stock basket before an order is placed, including estimated spread, participation in daily volume, market impact, volatility, and portfolio breakdowns. It returns a GO, NO-GO, or MODIFY verdict with reasoning; these verdicts are decision support, not investment recommendations.

An investor can consider EV/EBITDA separately as a valuation measure while using a pre-trade check to examine execution conditions and basket-level risks. PreTrAIde does not place the trade.

## Common mistakes

- **Treating EBITDA as cash flow:** It excludes interest and taxes and does not subtract capital expenditures or changes in working capital.
- **Comparing unlike figures:** Mixing forecast EBITDA for one company with historical EBITDA for another, or using different definitions of adjusted EBITDA, can distort comparisons.
- **Ignoring difficult denominators:** If EBITDA is zero or negative, the ratio is generally not meaningful as a conventional positive valuation multiple.
- **Assuming debt disappears:** EV includes debt and subtracts cash in the simplified calculation; debt still creates obligations.
- **Reading the multiple as a trading signal:** It does not capture execution costs or, by itself, establish whether a stock is suitable for a particular basket.
