EV/Revenue (Enterprise Value to Revenue)

The EV/Revenue ratio (also called EV/Sales) compares a company's enterprise value (market cap + net debt) to its total revenue. It is calculated as Enterprise Value divided by Annual Revenue. This multiple is primarily used for valuing companies that are not yet profitable or have volatile earnings, where metrics like P/E or EV/EBITDA cannot be meaningfully applied.

EV/Revenue gained prominence during the tech boom and became the default valuation metric for high-growth SaaS companies, biotech startups, and other businesses prioritizing revenue growth over near-term profitability. The rationale is that revenue is harder to manipulate than earnings, and fast-growing companies will eventually convert revenue to profits. During 2020-2021, some high-growth SaaS companies traded at 30-50x revenue, reflecting extreme optimism about future profitability.

However, EV/Revenue has significant limitations. It tells you nothing about profitability — a company with 80% gross margins deserves a much higher EV/Revenue multiple than one with 30% margins because more of each revenue dollar converts to profit. It also does not distinguish between recurring and one-time revenue, or between organic and acquisition-driven growth. For meaningful analysis, EV/Revenue should be used alongside margin expectations: if a SaaS company trades at 15x revenue and is expected to achieve 25% operating margins at maturity, the implied EV/Operating Profit at maturity is 60x — still expensive. The metric is most useful when comparing companies within the same industry that have similar margin profiles and growth trajectories.
