When a CEO unexpectedly leaves or is terminated, the reasons may be unclear, yet the impact on the organization can be profound. Such unplanned departures often create uncertainty about the organization’s future and its executive leadership, leading to reduced morale, diminished investor confidence, and a drop in performance. But what does the research reveal about the effects of sudden CEO departures on organizational outcomes? Let’s take a closer look..

The Research: A Moderate to Significant Impact on Organizational Performance

Studies examining the impact of CEO departures on organizational performance have yielded mixed results. Some studies suggest that there is a moderate impact on performance following an unplanned CEO departure, while others suggest that there can be a significant impact.

The University of Pennsylvania conducted a study that revealed organizations with an unexpected CEO departure suffered a 3.3% decrease in return on assets and a 7.4% decrease in return on equity.¹ A study by the University of Notre Dame found that organizations with unplanned CEO departures experienced a 6.8% decline in market value.²

Additional studies have identified a stronger negative correlation between unplanned CEO succession and organizational performance. One recent study examined the relationship between total shareholder returns and succession characteristics across over 2,500 companies from 2000 to 2014. The findings revealed that companies dismissing their CEO lost an average of $1.8 billion in shareholder value compared to those with a prearranged succession plan — regardless of whether the successor came from within or outside the organization.³ Furthermore, large organizations that experienced forced CEO successions would have generated an estimated additional US$112 billion in market value on average over the year before and the year after the CEO’s departure if had been part of a planned succession.⁴ This represents a substantial loss of shareholder value.

Factors That Contribute to the Impact of Unplanned CEO Succession

What explains these varied results? The impact of an unplanned CEO departure depends on several factors, including the circumstances surrounding the departure, the industry in which the organization operates, and the strength of the organization’s executive leadership team.

1. Loss of Business Continuity

When the leader of an organization suddenly departs, it can cause significant disruptions in business operations. This disruption can lead to a loss of revenue, damaged customer relationships, and decreased employee morale. Additionally, without a CEO succession plan in place, organizations may struggle to find the right candidate to fill the open position, leading to a prolonged period of uncertainty.

2. Leadership Void

A CEO departure can create a leadership void, which can be particularly concerning if the departing CEO was well-regarded by investors or had a long tenure with the organization. Investors may worry about whether the organization will be able to find a suitable replacement quickly and whether the new CEO will be able to provide the same level of leadership as the departing CEO.

3. Reputational Damage

In some cases, the circumstances surrounding a CEO’s departure can damage the organization’s reputation. For example, if the CEO is forced to resign due to allegations of misconduct or poor performance, investors may worry about the organization’s culture and governance practices. This can further erode investor confidence in the organization.

4. Negative Impact on Organizational Culture

The sudden departure of a key leader such as a CEO can create great uncertainty and anxiety among employees, leading to a negative impact on organizational culture. Employees may feel that the organization doesn’t value their contributions or that their future with the organization is uncertain. This can lead to decreased morale, lower productivity, and an overall decline in organizational performance.

Given the high costs of not having a CEO succession plan in place, it’s not surprising that many organizations choose to announce C-Suite leadership succession plans far in advance of an executive’s departure.

How to Mitigate the Impact of Unplanned CEO Departures

One factor that can mitigate the negative impact of an unplanned CEO departure is strong CEO succession planning. Organizations that have a clear succession plan in place are better equipped to handle a sudden leadership change and can minimize the disruption to business operations.

The Critical Role of Strong Succession Planning in Securing Your Organization’s Future

Research from the National Bureau of Economic Research found that organizations with robust succession plans in place experienced a lesser decline in performance after an unplanned CEO departure.⁵ These organizations were better equipped to maintain business continuity and were able to quickly appoint a new CEO to guide the organization forward.

Effective succession planning also helps soften the blow to employee morale and investor confidence often caused by an unplanned CEO departure. When employees see a clear plan for leadership continuity, they feel more secure in their roles. Publicly announcing a succession plan reassures stakeholders that the organization is prepared for leadership transitions, easing concerns and uncertainty. This proactive approach instills greater confidence in the organization’s future leadership among investors.

The impact of unplanned CEO departures on organizational performance is complex and influenced by multiple factors. While some studies indicate minimal impact, others highlight significant effects. One thing is certain: organizations with strong succession plans are better prepared for sudden leadership changes, more likely to sustain business continuity, and better positioned to protect overall performance
