Trailing Twelve Months (TTM), also known as Last Twelve Months (LTM), is a financial metric methodology that aggregates a company's financial data — such as revenue, EBITDA, net profit, or EPS — for the most recent 12-month period ending on the most recent reporting date, rather than using the most recently completed full financial year. TTM figures are calculated by taking the full-year figures from the most recent annual report and adding the current year-to-date figures while subtracting the equivalent prior year period — ensuring the most up-to-date representation of performance. For example, if a company's FY25 annual report is available and Q1 FY26 results have been published, the TTM revenue would be FY25 revenue minus Q1 FY25 revenue plus Q1 FY26 revenue. In Indian equity analysis, TTM P/E ratios, TTM EV/EBITDA, and TTM earnings growth rates are the preferred basis for valuation — since they reflect the most current operating performance rather than potentially stale full-year figures that may be 9 to 12 months old. Most financial data providers and screeners in India — including NSE, BSE, and Screener.in — publish TTM-based financial metrics for all listed companies.
