The Last Twelve Months (LTM), also known as trailing twelve months (TTM), is a period commonly used to evaluate the financial performance of a company over the past year. This period is not fixed to a calendar year but instead represents the most recent twelve-month span for which data are available.
Importance in Financial Analysis
Consistent Performance Evaluation
By using LTM, analysts and investors can ensure a consistent and up-to-date evaluation of a company’s performance, independent of seasonal variations or specific calendar periods.
Real-Time Analysis
The LTM metric provides real-time insights, reflecting the most current financial status, allowing more accurate comparisons and trend analyses.
Application in Valuation Metrics
LTM data is crucial for calculating various financial ratios and valuation metrics such as P/E (Price to Earnings), EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization), and EBIT (Earnings Before Interest and Taxes) multiples.
Calculation Methods of LTM
Formula
One common method to calculate LTM is to sum the data from the four most recent quarterly reports:
Alternatively, for companies that report annually, the LTM can be derived from subtracting the prior year’s corresponding figure from the most recent annual figure:
Example Calculation
Consider a company with reported quarterly revenues of:
- Q1: $10 million
- Q2: $12 million
- Q3: $15 million
- Q4: $13 million
LTM Revenue = $10 + $12 + $15 + $13 = $50 million
Historical Context and Evolution
The concept of LTM has evolved with the need for more timely and relevant financial data. Traditionally, annual reports were the primary source of financial performance. However, the advancement of data collection and analysis tools has made LTM a standard for contemporary financial analysis.
Special Considerations
Seasonality
While LTM smooths out seasonal impacts, it may not fully eliminate the effects if a business experiences significant seasonal trends.
Data Reliability
The accuracy of LTM calculations depends on reliable and consistent financial reporting. Inconsistent data or restatements can affect the precision of LTM figures.
