Thesis: Multiple re-rating

What it is

A specific subtype of undervaluation: the target trades at an inappropriately low multiple (P/E, EV/EBITDA, EV/Sales, P/NAV) relative to its peer group, business mix, or potential. Once the mis-categorisation is corrected, the multiple expands to peer levels — and the share price follows.

The thesis is not "earnings will grow"; it's "the market will pay more for the same earnings once it sees the business correctly".

When it's the right thesis

✅ The target trades at meaningful discount (≥20%) to direct peers on a comparable multiple
✅ The discount has a specific identifiable cause (legacy categorisation, governance overhang, capital structure, segment misperception)
✅ A catalyst exists or can be created to force re-rating (segment disclosure, governance change, breakup, peer revaluation)
✅ The peer multiple is sustainable (not cyclically inflated)
❌ Don't deploy if the discount reflects genuine business quality differences (the market is right)
❌ Avoid if the multiple gap has persisted for >5 years without closure — likely structural, not catalysed

Required deck content

Multiple comparison table: target vs. peers on 3–5 multiples
Decomposition of the gap: what % is mix, what % is governance, what % is sentiment
Specific catalyst: the event that forces re-rating
Re-rated valuation math: target multiple × current EBITDA = $ share price
Sensitivity by multiple

The deck's primary demand

"Take [specific action] to enable the market to value [target] at [X]× — in line with peers — implying $[Y] per share, [Z]% upside."

The action is what makes the multiple move: improved disclosure, governance reform, breakup, capital return — depending on the cause of the gap.
