Deep Dive: How to Value Companies with Negative Earnings — Beyond P/E Ratios
The price-to-earnings ratio is the most widely used valuation metric in investing. When someone asks whether a stock is cheap or expensive, P/E is usually the first number cited. But what happens when a company has no earnings — or worse, is losing money? The P/E ratio simply breaks down. A negative P/E is mathematically meaningless for comparison, and it tells you nothing about whether the stock is overvalued or a bargain. This isn't a niche problem. Some of the market's most closely watched companies operate at a loss. Rivian Automotive, with a market cap of $18.7 billion, reported a net loss of $3.6 billion in fiscal 2025. Snowflake, valued at $55.1 billion, posted a net loss of $1.3 billion in its most recent fiscal year despite growing revenue past $1.2 billion per quarter. Even Palantir, now profitable at $0.64 EPS, traded for years with negative earnings before its recent breakout to a $294 billion market cap. Investors who dismissed these companies because their P/E ratios were negative would have missed the opportunity entirely. Valuing companies with negative earnings requires a different toolkit — one that focuses on revenue growth, cash flow generation, balance sheet strength, and the trajectory toward profitability. This guide walks through the alternative valuation metrics that professional analysts actually use when earnings-based ratios fail, with real examples from today's market.
