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:

\text{LTM} = \sum_{i=1}^{4} \text{Quarterly\_Data}_i

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:

\text{LTM} = \text{Current\_Annual\_Data} - \text{Previous\_Annual\_Data}

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.

Annualized Data: Data that has been adjusted to show what the annual total would be if trends observed over a shorter period continued for a full year.
Year-over-Year (YoY): A method of evaluating financial performance by comparing data from the same period in different years.
Run Rate: A method of projecting future performance based on current data.

FAQs

Why is LTM favored over a calendar year?

LTM provides a more recent snapshot of a company’s performance, making it timely and relevant for ongoing assessments and financial decisions.

How often should LTM be recalculated?

LTM should be recalculated with the release of each new quarterly financial report to maintain its relevance and accuracy.

Can LTM be used for non-financial metrics?

Yes, LTM can be applied to various metrics, including operational performance indicators like customer churn rates or employee turnover, to provide a rolling view of performance.
