Run-rate EBITDA, explained simply
LTM looks back over twelve months. Run-rate asks what a full year would look like if the business continued at today’s level. It is relevant where the business has changed recently, and it is easy to overstate.
Buyers normally price on LTM and treat run-rate as supporting evidence, after testing for seasonality and for contracts that underpin the recent improvement.
Three views of annual EBITDA
IllustrativeAlder Creek Manufacturing, $ millions
Annualizing the strongest quarter overstates earnings by about $0.5 million, worth $4.0 million at 8.0x.
Calculation
- Quarterly run-rate = latest quarter EBITDA × 4
- Monthly run-rate = latest month EBITDA × 12
Worked example
| Alder Creek, $ millions | EBITDA |
|---|---|
| Q1 2026 | 1.1 |
| Q2 2026 | 1.2 |
| Q3 2026 | 1.3 |
| LTM to September 2026 | 4.7 |
| Q3 run-rate (1.3 × 4) | 5.2 |
Alder Creek Manufacturing, Inc. is a fictional company. All figures are illustrative.
The seller argues for $5.2 million and the buyer for the LTM figure of $4.7 million. At 8.0x the gap is worth $4.0 million. Q3 is historically the strongest quarter, at about 28% of annual EBITDA, so the buyer gives run-rate little weight.
Why it matters in a deal
Run-rate can fairly reflect real recent improvements, such as new contracts or price increases. It can also conceal seasonality or an unusually strong quarter.
Red flags
- Run-rate based on the single best month
- Seasonal businesses annualizing their peak season
- No signed contracts behind the recent improvement
