Which valuation approach involves annualizing current revenue to assess a business’s worth?

The correct option is Run Rate Valuation because this approach estimates the future performance of a business based on its current revenue figures. By annualizing current revenue—essentially projecting current monthly or quarterly revenues into an annual figure—Run Rate Valuation provides a straightforward method to gauge the business's potential earnings.

This technique is particularly useful for startups and businesses that may have recently scaled operations and are experiencing rapid growth. It enables investors to assess how the current revenue can translate into future financial performance if the same revenue levels are maintained over a year. It’s a quick way to set expectations for revenue performance without needing to delve into more complex forecasting or analysis.

In contrast, Book Value Valuation focuses on the company's assets and liabilities to determine its worth, Discounted Cash Flow Valuation relies on projecting future cash flows and discounting them to present value, and Market Capitalization evaluates a company's worth based on its stock price multiplied by the total number of outstanding shares. Each of these valuation methods has its own context and application but does not specifically involve the annualization of current revenue to evaluate the business's worth in the same direct way as Run Rate Valuation does.
