Year over Year (YoY)

Year over year is a financial comparison that evaluates performance metrics – such as revenue, profit, or growth rates – for a given period against the same period in the previous year. This approach helps identify trends, seasonality, and long-term growth patterns by controlling for time-based fluctuations. In M&A, YoY analysis is critical for assessing business momentum, forecasting accuracy, and the sustainability of financial performance.
