Private Equity LTM EBITDA Can Lag Current Monthly Earnings

Months Entering and Leaving

• A stronger month raises LTM EBITDA only by the amount it exceeds the month dropping from the trailing period at that point in the sequence.
• Several improved months can accumulate before the rolling total reflects the full change in current operating performance.
• A weak month leaving the period can lift LTM EBITDA even when the newest month is only holding current earnings steady inside the total.
• Comparison against budget, forecast, or prior-year EBITDA can produce different interpretations because each measure carries a different set of financial periods inside each calculation.

Current Earnings and the LTM Record

The distinction matters when a portfolio company has recently moved into a different earnings position. LTM EBITDA still contains earlier months, so its rate of change can understate a recent improvement or delay the full effect of deterioration until older periods leave the total.

That timing affects how current performance appears across management reporting without changing the accounting of any individual month. The rolling measure preserves a full twelve-month history; its movement carries more meaning when the months entering and leaving the period are read alongside the current monthly earnings pattern being reported.
