In finance, TTM stands for Trailing Twelve Months. It refers to data (like revenue, earnings, or profits) measured over the most recent 12-month period, rather than a fixed fiscal year. This helps investors see a company’s latest performance trends using up-to-date information. For example, “TTM revenue” means the total revenue a company earned in the past 12 months, giving a clearer and more current picture than annual reports alone.
