NMF

While NMF can have many meanings, it is often used as an abbreviation for "no meaningful figure." It's used in an accounting context when examining the financial data of a firm or comparing financial data between firms. You'll often see this when comparing financial data among companies where a certain ratio or figure isn't applicable to the company.

When analyzing a company, there are many metrics and ratios you can use. These metrics and ratios have different numerators and denominators. For example, if a company has negative earnings, it cannot have a P/E ratio. Earnings are in the denominator, and you can't divide by zero. The P/E ratio for a company with negative earnings might be replaced with "NMF." When analyzing companies across an industry, it might be a good idea to choose a ratio for which all of the companies you are examining have meaningful figures.

Instead of NMF, at times you might see NM, which means "not meaningful."
