What is an NTM multiple?
An NTM multiple — next twelve months — values a company against its forecast earnings for the coming year rather than its reported earnings from the past year. Where an LTM (last twelve months) multiple divides enterprise value by trailing EBITDA, an NTM multiple divides it by projected EBITDA for the next twelve months.
Because markets price businesses on where they are going, not where they have been, the forward multiple is often the more relevant lens — especially for growing companies. A business expected to grow earnings sharply will show a much lower NTM multiple than LTM multiple, because the denominator is the larger future number. The forward figure can make an apparently expensive company look reasonable, and vice versa.
The trade-off is that the NTM denominator is a forecast, not a fact. An LTM multiple rests on reported, auditable results; an NTM multiple rests on estimates that may not come true. The forward view is more relevant but less certain.
How NTM multiples are used
The forward multiple shows up wherever growth matters to valuation:
- Comparing growth companies. Two businesses can trade at the same trailing multiple but very different forward multiples if one is growing faster — the NTM view reveals which is actually cheaper relative to its trajectory.
- Building comp sets. Trading comps are often presented on both LTM and NTM bases, so a buyer can see how the peer group is priced against both history and expectation.
- Sanity-checking entry price. An entry multiple that looks rich on trailing earnings may look fair on next-year earnings if the growth is credible — but only if the forecast is sound.
- Reconciling the two. The bridge between LTM and NTM multiples is, in effect, expected growth. A wide gap is a signal to interrogate the forecast that drives it.
The discipline is to treat the forecast underneath an NTM multiple with the same skepticism as any projection. A forward multiple is only as trustworthy as the estimate in its denominator.
NTM versus LTM, and the forecast risk
LTM and NTM multiples are two views of the same business separated by the question of growth. LTM is backward-looking and verifiable; NTM is forward-looking and relevant. Neither is wrong — they answer different questions, and serious analysis usually looks at both.
The risk lives entirely in the NTM denominator. A flattering NTM multiple can be manufactured simply by adopting an optimistic forecast: assume aggressive growth and the forward multiple compresses, making the price look attractive. The honest use of NTM multiples therefore depends on the credibility of the underlying projection — which is why the forecast, not the multiple, is where the scrutiny belongs.
