Storytelling: the three headline reasons

What it is

A single slide, early in the deck (typically slide 3 — immediately after the thesis headline), that states in three numbered lines why the thesis is true.

It is the Minto Pyramid Principle made physical: the Big Idea on top, decomposed into three MECE (Mutually Exclusive, Collectively Exhaustive) supporting pillars below.

If a reader closes the deck after this slide, they should still be able to articulate your argument.

Why it works

• The mind handles three. Four+ become a list; two feel thin. Three is the sweet spot memory and rhetoric agree on.
• It pre-empts "what's your thesis?" every reader asks in the first 30 seconds. You give them the answer explicitly.
• It commits you to three specific claims — each of which the rest of the deck must support. This forces disciplined structure.
• It's the most quotable slide. Journalists, analysts and proxy advisors lift these verbatim into their coverage. Design for that.

Canonical structure

Each reason should hit three things:

1. [Gap / diagnosis] — quantified.
2. [Why the market hasn't priced it] — quantified.
3. [Path to realisation + reward] — quantified.

Every reason must be:

• Under 15 words
• Numeric (at least one figure per line)
• Specific (names the KPI, segment, or lever)
• Independent (removing one leaves the other two standing)

Worked examples

Pershing Square · McDonald's (Nov 2005)

1. McDonald's real estate is worth ~$46bn, ~94% of enterprise value.
2. Separating McOpCo reveals a 60% EBITDA-margin real estate business that re-rates to 12.5–13.5×.
3. Leveraged recap + buyback unlocks $45–50/share — 37–52% premium to $33.

Pershing Square · Canadian Pacific (Feb 2012)

1. CP has the worst operating ratio of any Class I railroad.
2. Under Fred Green, CP returned -18% while peers returned +22% to +93%.
3. Hunter Harrison transformed CN into best-in-class — he can do the same at CP.

Starboard · Darden (Sep 2014)

1. Darden underperformed direct peers by ~300% over 5 years under current board.
2. Operational plan adds $215–326M EBITDA — just 3.8% of current cost pool.
3. Sum-of-parts shows $67–86/share vs. $48 — before any Olive Garden turnaround.

Hindenburg · Nikola (Sep 2020)

1. The demo video was staged — the truck rolled downhill.
2. Founder Trevor Milton has a 20-year history of fraudulent claims.
3. No material product exists; the equity is a theatre.

Muddy Waters · NMC Health (Dec 2019)

1. Reported cash balance is fabricated — primary documents contradict the filings.
2. Related-party transactions have systematically transferred value to the chairman.
3. Book equity is significantly negative once adjusted; we remain short.

Trian · Disney "Restore the Magic" (Mar 2024)

1. Disney has destroyed >$200bn of shareholder value under the current board.
2. The board lacks the operational expertise to fix what they broke.
3. Adding Peltz + Rasulo closes the capability gap and refocuses capital allocation.

Design rules for the slide

• Numerals are serif, large. The 1, 2, 3 are visual anchors — render them in 64–100pt serif italic, accent colour, left of each line.
• Text is sans, medium weight, 22–28pt. Each reason on one line if possible.
• No bullets below the line. If a reason needs supporting sub-points, move them to the Complication section. This slide is the summit, not the evidence.
• White space above and below. Do not fill the slide. This is a moment; give it room.
• No chart, no icon, no stock image. Three lines of text. The typography IS the design.

Order of the three

A deliberately strategic question. Three ordering patterns recur:

1. Diagnosis → Opportunity → Path (most common, e.g. McDonald's 2005)
2. Gap → Cause → Remedy (management-change theses, e.g. CP 2012)
3. Promise broken → Current state → Required action (short-seller reports alleging fraud, e.g. Nikola)

Pick the order that matches the deck's core thesis type. Fraud exposés almost always lead with the broken promise (#3 ordering); operational turnarounds lead with the gap.

Common mistakes

1. Four reasons dressed as three. If reason 2 has a semicolon, you've got two reasons. Merge or move to another slide.
2. Qualitative adjectives. "Significant underperformance" is not a reason — "-18% TSR vs. +22–93% peer range" is.
3. Reasons that aren't MECE. If reason 1 and reason 2 argue the same thing from different angles, the reader registers it as filler. Ruthlessly MECE.
4. Saving the reward for later. The third reason must cash the cheque the first two wrote. Quantify the upside here, not only in the Answer section.
5. Starting with the solution. "Spin the real estate" is not reason 1 — it's reason 3. Lead with the gap/diagnosis.

How the skill should produce these

When drafting the three reasons with a user:

1. Ask for the Big Idea in one sentence first.
2. Draft 5–7 candidate reasons, each under 15 words, each quantified.
3. Eliminate duplicates / overlap → collapse to MECE set of 3.
4. Order using the pattern match above (diagnosis / gap / broken promise).
5. Check each reason against the rest of the deck: does the deck actually prove it? If not, strengthen the evidence in the Complication or cut the reason.
