Which of the following metrics reflects a company's potential earnings growth?

EBITDA, which stands for Earnings Before Interest, Taxes, Depreciation, and Amortization, is a key metric that reflects a company's operational performance and its potential earnings growth. By focusing on earnings generated from core business operations, EBITDA provides a clearer view of how well a company is positioned to generate future profits, independent of its capital structure and tax situation.

Investors often look at EBITDA to gauge a company's ability to increase its earnings over time, as it strips out factors that can obscure the underlying trends in profitability. A rising EBITDA suggests that a company is effectively managing its operational costs and generating more income from its core business activities, indicating strong potential for future growth.

Other metrics such as the P/E ratio offer insights into how a company’s current earnings are valued relative to its stock price, but they may not directly indicate future growth potential. Market capitalization provides a snapshot of a company's total value in the stock market but does not address earnings. Revenue is important as it indicates sales but does not account for profitability or the efficiency of operational management. Thus, EBITDA is a more telling metric for assessing a company's potential earnings growth.
