Thesis: Break-up / spinoff

What it is

You argue the target should be separated into two or more independent businesses — via spin-off, divestiture, REIT conversion, dual-listing unification, or carve-out IPO — because the parts are worth materially more than the whole.

This thesis type cross-references heavily with:

patterns/breakup-spinoff.md — the strategic moves available
patterns/sum-of-parts.md — the valuation engine
valuation/sum-of-parts.md — the analytical framework

This file is the thesis-level companion: when this is the dominant argument of the deck, what does the deck need to contain?

When it's the right thesis

✅ Multi-segment business with materially different growth rates, margins, capital intensities, or customer bases
✅ Conglomerate discount visible in current trading multiple vs. SoP of pure-play comps
✅ A precedent transaction in the sector validates the unlock
✅ Tax-efficient mechanics exist (Section 355 in US, demergers in EU)
❌ Tightly-integrated businesses (shared customers, R&D, manufacturing)
❌ Sub-scale parent (two micro-caps usually worse than one mid-cap)
❌ Founder-led / family-controlled where vote math fails

Required deck content

3-column "this is N businesses wearing one ticker" segment view
Sum-of-parts build-up table with peer-multiple sourcing
2–3 sector precedent transactions (with TSR outcomes)
Proposed structure: spin / sale / REIT / unification / carve-out
Tax mechanics: 355 status, expected friction costs
Implementation roadmap (announce → file → effective date)
Pre-emptive rebuttal of "loss of synergies" / "stranded overhead"
The big-number reveal slide

The four breakup archetypes

Conglomerate discount — multi-business holding with no synergies (DuPont, Disney, Phillips 66)
Hidden crown jewel — high-margin segment buried inside commodity parent (Pershing/McDonald's real estate, Trian/PepsiCo Frito-Lay)
REIT conversion — asset-heavy operator with separable real estate (Hilton/Park, MGM Growth, Darden)
DLC unification — historical dual-listed structure with structural discount (BHP, Rio Tinto, Unilever)

Common companion thesis types

theses/governance-board.md — board change often enables breakup
theses/capital-return.md — spin proceeds typically fund buyback
theses/management-change.md — new operators sometimes needed for separated entities

Exemplars

Pershing Square · McDonald's (Nov 2005) — REIT conversion template, 149-page thesis
Trian · DuPont (Feb 2015) — 6-segment industrial breakup; successful via Dow-DuPont merger → 3-way spin
Elliott · BHP Billiton (Apr 2017) — DLC unification + petroleum divestiture; both executed by 2022
Starboard · Darden (Sep 2014) — partial REIT + Specialty Restaurants spin
Elliott · Phillips 66 (2025) — midstream-spin thesis; partial win via board reconstitution + separation commitment
Trian · PepsiCo (Jul 2013) — snacks-vs-beverages SoP; refused but generated capital return
