The Drawbacks of EBITDA in Business Valuation: A Warren Buffett Perspective and More (2024)

EBITDA, or Earnings Before Interest, Taxes, Depreciation, and Amortization, is frequently used by many investors and analysts as a proxy for a company's operating performance. However, its credibility as a valuation tool has been the subject of much debate, particularly from respected figures in the investment community such as Warren Buffett.

Buffett, the CEO of Berkshire Hathaway, and regarded as one of the most successful investors globally, expressed his concerns about using EBITDA in his 1986 letter to shareholders. He notably stated that "Depreciation is an expense, exactly as sure as are labor costs and overhead" [(Buffett, 1986 Shareholder Letter)]. Buffett's statement emphasizes that depreciation, a non-cash expense, is an inevitable cost of doing business, essentially representing the wear and tear of assets. By excluding depreciation, EBITDA can lead to a misleadingly optimistic portrayal of a company's financial health.

Besides this inherent problem of ignoring depreciation, EBITDA has other considerable shortcomings:

1. Inaccurate Representation of Cash Flow: EBITDA overlooks changes in working capital, meaning it can inflate cash flow if a business has substantial growth in receivables or inventory. This oversight could lead to an overvaluation of a company, as cash flow is a critical element for business sustainability and growth [(Damodaran, 2012)].

2. Neglect of Capital Expenditures: EBITDA fails to take into account the necessity for businesses to reinvest in their operations for long-term survival and expansion. Capital expenditures, essential for maintaining and growing business operations, can have a significant impact on profitability, and not factoring these into the equation can lead to an inaccurate valuation [(Harvard Business Review, 2014)].

3. Insensitivity to Debt Levels:** EBITDA does not consider interest payments, which can lead to an overestimated valuation for heavily leveraged companies. High levels of debt can pose significant risks to a company's solvency, and any financial measurement that ignores such an essential factor can be misleading [(Investopedia, 2020)].

In light of these concerns, it becomes clear that while EBITDA can provide a snapshot of a company's operational performance, it should not be used as a standalone measure. A more comprehensive financial analysis, including factors such as depreciation, changes in working capital, capital expenditures, and debt levels, can provide a clearer picture of a company's overall health and long-term prospects. As investors, we should follow Warren Buffett's advice and see beyond the surface-level metrics to understand a company's true financial reality.
