Pattern: Management change

What it is

You argue the operator — almost always the CEO — is the binding constraint on the target's value, and propose a specific replacement (or a specific search criterion + interim CEO). The thesis: the strategy is fixable, the assets are fine, the people are not.

This pattern almost never travels alone. It pairs with villain naming (the diagnosis), governance critique (the mechanism — board change enables CEO change), and operational turnaround (what the new CEO will do).

Why it works

Operator-quality is the highest-leverage variable in equity performance. Pairing the right operator with the right asset can triple multiples.
Specific replacements convert sceptics. "Replace the CEO" is abstract; "Hunter Harrison closed the operating-ratio gap at CN by 18 points and can do the same here" is concrete.
It side-steps strategy debates. Management can argue your strategy is wrong; they can't credibly argue they shouldn't be the ones to execute it if their record proves otherwise.
Boards often want to act but lack cover. A public activist campaign provides the cover for an internal palace coup that was already simmering.

When to use it

✅ The CEO has been in place ≥3 years with documented underperformance
✅ Peer CEOs have demonstrably outperformed in comparable situations
✅ A specific successor exists — internal or external — with the relevant operating record
✅ The board has at least 1–2 members likely to support the change
❌ Don't deploy in the first 18 months of a new CEO's tenure
❌ Avoid in founder-controlled companies where board math doesn't work (Tesla, Meta, certain family businesses)
❌ Don't use as the primary lever if the issue is structural (conglomerate discount, regulatory shift) — even a great new CEO can't fix structure quickly

The three replacement archetypes

1 · The operator-for-operator swap

You name a specific individual who has done the exact thing the target needs. This is the most powerful version. Requires the candidate's willingness (often pre-arranged before the deck publishes).

Pershing Square / CP 2012: Hunter Harrison (CN's transformative CEO) for Fred Green. Hunter joined as part of the activist slate. CP's operating ratio went from 81% to 64% within 4 years.
Ancora / Norfolk Southern 2024: Jim Barber (former UPS COO) for Alan Shaw, paired with Jamie Boychuk (PSR specialist, ex-CSX).

2 · The interim + search

You don't name a permanent successor; you name an interim and a specific search criterion. Used when:

A specific operator isn't available
The board needs cover to run the search itself
You want to avoid being seen as installing a hand-picked CEO
Elliott / various campaigns: typically nominates a search-firm process with criteria embedded in the proxy.

3 · The structural CEO move

The current CEO is replaced as part of a broader role re-organisation: CEO/Chair separation, executive-chairman creation, COO promotion to CEO. Used when removing the CEO outright is politically too hard.

Trian / Procter & Gamble (2017): Peltz's move was for board representation that would constrain CEO discretion, not direct CEO removal.

Anatomy of the slide sequence

Slide N:   "[CEO name] has not delivered."
           5-year TSR vs. peers, with their tenure annotated.

Slide N+1: "The decisions [CEO] has owned." 
           A list of specific value-destructive moves with dollar amounts.

Slide N+2: "What this company needs in its next CEO."
           A specific skills + experience profile (not generic).

Slide N+3: "[Successor name] meets every criterion."
           One-pager bio. Career arc. The specific gap they have closed
           at a comparable target.

Slide N+4: "Comparable transformations."
           Table of 3–5 cases where a new CEO closed a similar gap, with
           outcome data.

Slide N+5: "Our slate enables this change."
           Director nominees who will hire the successor.

The Hunter Harrison / Canadian Pacific deck remains the gold standard of this sequence — it's worth studying as a single unit.

Language that works

"Under [CEO], [metric] has [declined / stagnated]."
"[Successor] has done exactly this before, at [precedent], producing [outcome] in [timeframe]."
"This company's strategy is correct. The execution is the constraint."
"Operating performance like [target's] does not get fixed by the same person who delivered it."
"We propose [name] not because we disagree with the company's strategy — but because we agree with it and want to see it executed."

Common mistakes

Naming a successor without their consent. Embarrassing if they decline publicly. Always pre-arrange.
Vague successor profile. "World-class operating CEO" doesn't compel anyone. The profile must be so specific that one or two names obviously fit.
Attacking the CEO without a board mechanism. Without governance change (or board willingness), the CEO doesn't go.
Ignoring CEO compensation overhang. If the CEO has $80M of unvested equity, the board cost of removal is real. Address it.
Treating M&A acquisition CEO change as the same. A CEO who built the company over 25 years is removed differently than a hired-in operator. Adjust rhetoric.

Exemplars

Pershing Square · Canadian Pacific (Feb 2012) — the archetype. Hunter Harrison nominated as part of the slate, joined post-vote.
Starboard · Darden (Sep 2014) — Clarence Otis already retiring; the campaign forced acceleration + a specific successor profile.
Ancora · Norfolk Southern (Apr 2024) — Jim Barber as named successor, Boychuk as PSR specialist.
Greenlight · Peloton (Oct 2024) — argued the existing CEO Stern's cost-out program is correct; future bull case requires continuity but operating discipline.
Engine Capital · Parkland (2023–2024) — multi-deck campaign ultimately leading to CEO turnover.
Trian · "Restore the Magic" Disney (Mar 2024) — Bob Iger framed as transitional; Peltz/Rasulo board roles to enable search.
