Two Succession Dates: Name the Successor, Then Share the Chair

Set the first date before the board can guess

You are not choosing a successor for the next board meeting. You are deciding who will own the company's next decade. Poorly run chief-executive and senior-team changes erase nearly $1 trillion of S&P 1500 market value each year, and $546 billion of that loss traces to three reinforcing failures. A founder-led business will change hands, and the question is whether that change is decided by the people who built it or by the people watching it. A mystery heir creates risk. Customers, lenders, employees, and rivals react to uncertainty; the company pays in attention, patience, and capital.

At JCB, George Bamford, 45, will hold the chair jointly with his father, Lord Bamford, from 1 October. It is JCB's first change at the top in over 50 years. Lord Anthony Bamford has been chairman since 1975. Earlier May reports that George would succeed his father caught some observers off guard, because they had expected his older brother Jo as the successor.

The surprise is the warning. If outsiders can guess the heir before the family does, the family has not finished planning. A durable business removes that ambiguity on its own schedule, naming the successor before the chair changes and using the overlap to prove the successor can lead.

The plan needs two dates, not one

Only 8% of boards start CEO succession planning more than five years out. A short overlap is a problem for a company measured in decades. The plan needs two dates: one public, one operational.

• Name the successor before the seat changes. The mark is a clear statement to employees, customers, and lenders: this person will lead, and the current owner will remain available for a defined overlap. The name should be specific, not a title; a successor-in-waiting is a rumor, while a named successor is a decision.
• Set the overlap before the first meeting. The agreement should cover what the outgoing owner will do, what the successor will decide alone, and what will be reviewed together. It should span the first major cycle: a budget, a product launch, or a capital decision.
• Give the successor a measured period of authority. Authority is visible when the company can point to at least one major call made by the successor, with the founder available but not intervening. Owners often treat the overlap as a second full-time job for the founder, turning a transition into shared command and weakening authority.
• Share the chair only after the successor has earned the board's confidence. The handover is visible in a joint chairmanship or a clear step back from daily decisions. JCB's 2025 pre-tax profit was £642m, down from £687.3m in 2024. 2025 turnover slipped to £5.7bn from £5.8bn. Its 2025 machine count fell 5.2% to 113,498 units. The transition is a planned change in a still-operating business.
• Keep the outgoing owner through the transition. The founder remains available for institutional memory, key relationships, and the first hard problem after the handover. Across S&P 1500 founder transitions, founder chief executives stayed 21 years on average before stepping down, and 45% kept a board chair afterward, against 33% for non-founder CEOs. Founders tend to stay close; the company should decide whether that staying is a role or a habit.

Make the overlap a test, not a title

A co-chairman transition works when the second date is a test, not a title. The successor must be seen making decisions, not merely sitting beside the founder; the founder must be seen stepping back, not merely sharing a title.

Across S&P 1500 companies, 21% of founder-successor CEOs named between 2015 and 2022 were replaced within two years, against 16% of all S&P 1500 CEOs named in that window. The gap is the cost of a weak overlap. A successor named too late, tested too briefly, or protected too long will be judged by the first mistake. The company should expect the mistake and design the overlap so it can be absorbed.

In a set of 200 American firms that used a chair who also ran the company, 54% trailed peer companies while that chair held the role, with an average shortfall of 14%. That argues for a shared role with a clear end, not a permanent second seat. The chair should be a defined handover with a date for the outgoing owner to step back.

During the first nine months of 2026, 58% of TSX-listed boards began a CEO search while the outgoing chief executive was still in place. The pattern is common, but it is not good for a founder-led business. The successor should be named before the board starts looking, not after the exit is visible.

Set the two dates now: name the successor publicly before the seat changes, then share the chair for a defined overlap so the outgoing owner remains through the transition.
