Emergency CEO succession: a 72-hour checklist for boards

A CEO can become unavailable overnight: a serious illness, an accident, a sudden resignation, an investigation or a dismissal that cannot wait. In that moment the board is no longer overseeing the company; it is the only body able to lead it. What happens in the first 72 hours shapes how employees, clients, lenders and regulators judge the organisation for months.

Why every board needs an emergency succession plan

Most boards discuss long-term succession: who could lead the company in three or five years, and how to develop them. Far fewer have agreed what happens if the CEO is gone tomorrow morning. The two are different exercises. Long-term succession is about choosing the right leader. Emergency CEO succession is about continuity: keeping decisions flowing, protecting value and buying the board time to choose well.

Without a plan, the first hours are spent on questions that should have been settled in calm conditions. Who convenes the board? Who signs payments and contracts tomorrow? Who speaks to the largest client, the bank, the press? Each unanswered question becomes a small vacuum, and vacuums are filled quickly by rumour, internal rivalry or outside pressure.

In a crisis, a board does not rise to the occasion. It falls back on what it prepared.

What should exist before the call comes

An emergency succession plan is short. It should fit on a few pages, be reviewed every year and be known by the chair, the committee responsible for nominations, the general counsel or company secretary and the person named as acting CEO. Its value lies less in the document than in the decisions it records in advance.

The choice of acting CEO deserves particular care. It is usually the CFO, the COO or a senior executive with the trust of the team; occasionally the chair or a non-executive director steps in. What matters is that the person can run the business for several months, is accepted by the leadership team and understands that the role may or may not lead to the permanent position.

Some boards go one step further and walk through a short scenario once a year: the CEO is unreachable on a Monday morning, what happens next? An hour of discussion around the table usually reveals gaps that no document would have shown, from an expired signing mandate to a key client relationship held by one person only.

Hour 0 to 24: convene, decide, contain

The first day is about control. The board should meet, in person or remotely, within hours rather than days. The chair leads; if the chair is conflicted or unavailable, the senior independent director or deputy chair takes over.

• Establish the facts. What has happened, what is known, what is not yet known and what is confidential. Separate verified information from assumption.
• Appoint the acting leader. Activate the name in the plan, or decide on an alternative if circumstances have changed. Confirm the appointment formally and record it in the minutes.
• Confirm authority. Activate the delegation of authority so that payments, contracts and operational decisions can continue the next morning.
• Check legal and disclosure obligations. With counsel, review in general terms what must be notified, to whom and by when, including any market disclosure for listed companies and requirements under financing agreements.
• Make the first calls. The chair, or the acting CEO, speaks personally to the most critical stakeholders: major shareholders, the main lender and, where relevant, the regulator.
• Protect the person concerned. In cases of illness or personal crisis, respect privacy and agree what will and will not be said.

Hours 24 to 72: communicate and stabilise

Once authority is clear, the priority shifts to confidence. People inside and outside the company want to know three things: who is in charge, whether the strategy changes and what happens next. Silence is interpreted as disorder.

Employees should hear the news from the company before they read it elsewhere. A short message from the chair, followed by a meeting or call led by the acting CEO, is usually enough at this stage. Clients and partners need reassurance about continuity: the same teams, the same commitments, a clear point of contact. Lenders and regulators expect factual, timely information and a credible plan. Media enquiries should be handled by a single spokesperson with agreed lines.

The leadership team is the most fragile point. An unexpected departure at the top can trigger quiet competition for the role, anxiety about the future or the departure of loyal lieutenants. The chair should speak individually with each member of the executive committee, clarify expectations and, where needed, consider retention measures for people who are critical to continuity.

Weeks 1 to 4: from stabilisation to decision

By the end of the first week, the company should be operating normally under interim leadership. The board can then turn to the strategic question: how and when to appoint a permanent CEO.

• Assess the situation honestly. Is the absence temporary or permanent? Is the acting CEO a credible long-term candidate, or a steady pair of hands for a defined period?
• Choose the route. Confirm the acting CEO, bring in an experienced interim executive or launch a full search. Each option has different implications for speed, risk and signal.
• Define the role for the next phase. The company may need a different profile from the departing CEO. Review strategy, ownership expectations and the leadership team before writing the brief.
• Launch the search if required. Agree the process, the timeline, the internal candidates to be assessed alongside external ones and the level of confidentiality.
• Review the plan itself. Record what worked and what did not, and update the emergency succession plan accordingly.

The board should resist two temptations: appointing the acting CEO permanently by default, simply because the crisis has passed, and launching a rushed external search before the brief is clear.

Preparation is the plan

An emergency succession plan will, with luck, never be used. Its real benefit is earlier: it forces the board to name a successor for the worst case, to understand the depth of the leadership team and to agree how it will behave under pressure. Boards that have done this work spend the first 72 hours executing. Boards that have not spend them negotiating. The difference is visible to every employee, client and investor watching how the company responds.
