Interim or permanent? The board’s choice after a sudden CEO exit

A chief executive can be gone within a week: a resignation to join a competitor, a health problem, a dismissal after a loss of confidence. The board then faces two decisions that are easy to confuse: who runs the company tomorrow, and who should lead it for the next five years. Treating them as one decision is the most common and most expensive mistake.

The first 72 hours: stabilise before you decide

In the first three days, the board’s task is not to find a successor. It is to show that the company is governed. Employees, lenders, investors, major customers and, in regulated sectors, supervisors will all draw conclusions from silence.

• Confirm who holds authority. Name a person responsible for day-to-day decisions, even provisionally, and check signing powers, bank mandates and delegations.
• Establish the facts. Understand why the CEO left, what was in progress and whether the departure triggers any commitments, disputes or disclosure obligations.
• Agree one message. A short, factual statement to staff and key stakeholders, approved by the board, with a clear owner for questions.
• Review contractual triggers. Financing documents, shareholder agreements and key customer contracts sometimes contain key-person or change-of-management clauses.
• Set a governance rhythm. A small board committee, meeting frequently, with a mandate to recommend both the interim and the permanent solution.

Boards with a written emergency succession plan move through this phase in hours. Those without one tend to improvise, and improvisation is visible from outside.

The first 90 days: four realistic options

Once the company is stable, the board has roughly a quarter to settle the leadership question properly. There are four realistic options, and each sends a different signal.

Internal acting CEO

A member of the executive team, often the CFO or COO, steps up while keeping or delegating their own role. It is the fastest and least disruptive option, and it recognises internal talent. It works when the strategy is clear and the business needs continuity rather than a change of direction.

Chair as executive chair

The chair takes on executive responsibilities for a defined period. This can reassure investors and lenders, particularly when the chair knows the business well. It also blurs the line between oversight and management, and leaves the board without its independent leader at the moment it most needs one.

External interim CEO

An experienced executive is brought in for a defined mandate, typically from several months to a year. A good interim arrives without a career agenda inside the company, can take difficult decisions quickly and has usually handled similar situations before. The price is a learning curve and the need to manage the executive team’s reaction to an outsider.

Accelerated permanent search

The board moves straight to appointing a permanent successor, sometimes from a pre-identified internal or external pool. Where succession planning has been done properly, this can be the right answer. Without it, compressing a search means choosing from a narrow and poorly assessed field.

After a sudden exit, the question is not who is available, but what the company needs for the next six months, and whether that is the same as what it needs for the next five years.

Five criteria to choose between them

1. Stability or transformation. If the strategy holds and the team is strong, continuity favours an internal acting CEO. If the departure exposed deeper problems, such as weak performance, a difficult culture or a stalled plan, an external interim with a clear mandate may be needed before anyone permanent is hired.
2. Readiness of internal candidates. An acting role is a genuine test, but only for someone close to ready. Placing an unready executive in the role and then appointing someone else above them is a reliable way to lose a strong member of the team.
3. Stakeholder signals. Lenders and investors read the interim choice as a statement about control and risk. Employees read it as a statement about continuity and opportunity. The board should decide which audiences matter most at this moment.
4. Expected duration. A permanent CEO search rarely takes less than several months, plus notice periods. The interim arrangement must be sustainable for that time without exhausting the person or the team around them.
5. Board capacity. An executive chair arrangement only works if the rest of the board can still provide independent challenge, usually led by a senior independent director.

Options, fit and risks at a glance

Option	When it works	Main risks
Internal acting CEO	Clear strategy, strong executive team, a credible internal candidate	Overload from a dual role; the candidate is weakened if not appointed; status quo by default
Chair as executive chair	Chair with deep knowledge of the business; investors want visible control; short horizon	Weaker oversight; difficulty stepping back; may deter external candidates
External interim CEO	Turnaround, restructuring, conflict within the team, or no ready internal option	Learning curve; resistance from the team; mandate creep if objectives are vague
Accelerated permanent search	Succession plan in place, pre-assessed candidates, stable business	Narrow field; insufficient assessment; a decision driven by pressure rather than fit

How an interim can de-risk the permanent appointment

An interim period is not lost time. Used deliberately, it improves the quality of the permanent decision.

• It sharpens the brief. An interim sees the business as it is, not as it appears in board papers, and can tell the board what the next CEO must actually be able to do.
• It clears difficult decisions. Restructuring, disposals or changes in the leadership team can be completed before the permanent CEO arrives, giving them a cleaner start.
• It removes time pressure from the search. With operations in steady hands, the board can run a complete process and assess candidates properly.
• It creates an observation window. Internal candidates can be given wider responsibilities and observed under real conditions.

Two rules matter. First, the interim’s mandate must be written down: objectives, decision rights, duration and reporting line. Second, the board must decide at the outset whether the interim is a candidate for the permanent role. Either answer can work; ambiguity does not, because it distorts the interim’s incentives and unsettles the team.

Communication: early, brief and consistent

Most of the damage after a sudden departure comes from what people infer, not from what they are told. A few principles hold in almost every case.

• Announce the interim arrangement and the process for a permanent appointment together, so the interim is not read as the final answer.
• Brief lenders, major shareholders and key customers personally, before or alongside any public announcement.
• Give the executive team more context than the wider organisation, and ask them to carry the message.
• Respect confidentiality and legal constraints around the reason for departure, and do not speculate.
• Set a date for the next update, and keep it.

Separate the two decisions

A sudden CEO departure feels like a crisis, but it is also a moment to ask what kind of leadership the company needs next, rather than replacing like with like. Boards that separate the immediate decision from the long-term one, choose the interim solution for what it is meant to achieve and give the permanent search the time and rigour it deserves usually end up with a stronger appointment than the one they lost. The work starts before the crisis: an up-to-date emergency succession plan turns 72 hours of improvisation into 72 hours of execution.
