LTM vs NTM multiples: Answer Guide 2027

LTM (last twelve months) multiples use trailing actual financials, while NTM (next twelve months) multiples use forward analyst estimates. NTM multiples are generally preferred in trading comps because markets price expectations, not history. In an LTM NTM interview, define both, explain the preference, and know when LTM wins.

LTM NTM Interview Questions: What They Test

Interviewers want to see that you think like the market. Stock prices discount the future, so dividing by last year's EBITDA mixes a forward-looking numerator with a backward-looking denominator. NTM multiples align both sides on expectations — which is why bankers' comps tables lead with NTM EV/EBITDA.

But LTM has its place. For companies with no analyst coverage, unreliable estimates, or one-off distortions in forecasts, LTM is the honest number. Strong answers also note the manipulation risk: NTM depends on estimates that can be stale or biased, so practitioners cross-check both.

How to Answer an LTM NTM Interview Question

Define both. "LTM is the trailing twelve months of actuals; NTM is the coming twelve months of consensus estimates."
State the preference. "NTM is standard in comps because equity value reflects future cash flows."
Give the exception. "Use LTM when estimates are unreliable — no coverage, binary outcomes, or post-earnings estimate lag."
Show both. "Best practice is showing LTM and NTM side by side; a wide gap between them tells its own story about expected growth."

Common Mistakes in LTM NTM Interview Answers

Saying LTM is "wrong." It is not wrong — it is just backward-looking; dismissing it entirely looks dogmatic.
Blindly trusting NTM. Estimates can be stale after news — always ask how fresh the consensus is.
Mixing periods. Applying an NTM multiple to LTM EBITDA (or vice versa) without disclosure is a real-world error interviewers probe for.
