If the internal bench includes candidates comparable to the best external options, the board is faced with a difficult decision: is it better to promote internally or bring in an outsider? Most directors know the broad trade-off. Internal hires offer continuity and deep organisational knowledge. External candidates bring fresh perspectives and the opportunity for a new direction. But when is continuity more important than new perspectives? When is the need for a reset worth the time it takes an external hire to get up to speed? This article explores the research on internal vs external CEO prevalence, tenure and performance, and the commercial scenarios that can guide boards on the most appropriate choice for their context. PART ONE ## The data on internal vs external CEOs ![Gold line icon of two documents side-by-side connected by a bottom line. One with a line graph and the other with a bar chart, representing comparative data analysis.](https://sterlingblack.com/hs-fs/hubfs/Internal%20vs%20External%20CEO%20Succession%20Whitepaper/chapter-1-icon.png?width=155&height=155&name=chapter-1-icon.png "Gold line icon of two documents side-by-side connected by a bottom line. One with a line graph and the other with a bar chart, representing comparative data analysis.") ### Prevalence Internal promotions represent [two-thirds of new CEOs](https://www.conference-board.org/press/ceo-succession-2025), but outsiders are on the rise. In the S&P 500, external CEO hires nearly doubled from 18% in 2024 to 33% in 2025. This is the highest level in eight years. In APAC, there is still a stronger preference for internal candidates, with [83% of new CEOs](https://www.russellreynolds.com/en/about/newsroom/firms-prioritise-internal-ceos-amidst-rising-turnover) coming from inside the company in 2025. The region also had a higher rate of first-time CEOs at 97% compared to the global average of 88%. ![Graph displaying internal vs external CEO appointments globally in 2024 and 2025, compared to APAC 2025.](https://sterlingblack.com/hs-fs/hubfs/ceo%20appointments.png?width=500&height=500&name=ceo%20appointments.png "Graph displaying internal vs external CEO appointments globally in 2024 and 2025, compared to APAC 2025.") ![ceo terminations](https://sterlingblack.com/hs-fs/hubfs/ceo%20terminations.png?width=500&height=500&name=ceo%20terminations.png "ceo terminations") ### Tenure A [2012 study](https://www.forbes.com/sites/susanadams/2012/05/25/new-ceo-study-underlines-merits-of-promoting-from-within/) found that insiders stayed one year longer than outsiders on average. This has remained relatively consistent throughout the years, with [2024 research](https://www.russellreynolds.com/en/insights/reports-surveys/global-ceo-turnover-index/the-transformation-of-the-ceo) measuring internal CEOs’ average tenure at 8.7 years compared to external CEOs’ 7.3 years. One contributing factor is likely the failure rate – 30% of external CEOs are fired compared to 24% of internal CEOs, according to an [analysis of CEO turnover](https://mss-p-053.stylelabs.cloud/api/public/content/rra-the-next-ceo-2023-report.pdf) in publicly listed companies in 2023. ### Performance [Internal CEOs perform better](https://www.sciencedirect.com/science/article/abs/pii/S0024630124000724) than their external counterparts across a variety of metrics. Companies with new internal CEOs [outperform their regional stock market index by 4.4% on average](https://www.forbes.com/sites/susanadams/2012/05/25/new-ceo-study-underlines-merits-of-promoting-from-within/), compared to 0.5% for those hiring externally. Companies with internal CEOs also [perform better on Return on Assets and Tobin’s Q measures](https://www.emerald.com/mf/article-abstract/50/11/1920/1212946/Internal-versus-external-CEO-hires-key-differences). This was despite the fact that outsiders often looked better on paper – they were more likely to have earned an MBA, attended an elite university or majored in STEM. Not all organisations who hire an external CEO will see a negative impact on company performance. Companies who hire outsiders typically have [lower total return to shareholders (TRS)](https://www.directorsandboards.com/board-duties/board-ceo-relationship/risks-and-rewards-of-internal-and-external-ceo-candidates/) in the three years before a transition than those that hire insiders. Due to the [rebound effect](https://clsbluesky.law.columbia.edu/2024/12/02/why-companies-choose-ceos-from-outside-or-within/), these companies will see marginal improvements to TRS in the three years after an external CEO hire. However, this reflects the tendency for [profitability to return to average levels](https://papers.ssrn.com/sol3/papers.cfm?abstract_id=5014263) after extreme lows. 1Return on Assets measures how efficiently a company uses its assets to generate profits. Tobin’s Q is the ratio between a company’s market value and the replacement cost of its assets. 2Total return to shareholders measures the gain an investor receives from a stock, combining stock price increases and dividend income. PART TWO ## Commercial scenarios favouring internal CEO succession ![Gold line icon of a magnifying glass highlighting a person, with two additional people in the background, representing internal CEO talent search.](https://sterlingblack.com/hs-fs/hubfs/chapter-2-icon.png?width=155&height=155&name=chapter-2-icon.png "Gold line icon of a magnifying glass highlighting a person, with two additional people in the background, representing internal CEO talent search.") Boards should consider the case for internal succession in the following scenarios: ### Scenario 1: Stable market leadership with consistent performance Continuity matters more than reinvention when a company holds a strong market position. Boards should resist external pressure to introduce an outsider when the risk is unnecessary. ### Scenario 2: Strategic transformation projects are already underway Bringing in an external CEO mid project can stall progress while they get up to speed. Internal CEOs have a flatter learning curve and can maintain project momentum. ### Scenario 3: Complex or regulated industries Where organisational knowledge or technical experience is a core part of business, insiders are a better choice. The advantages that an outsider offers are usually lost in the years required to build credibility and expertise. ### Scenario 4: Strong corporate culture or brand identity Stakeholders tend to view insiders as preserving an organisation's brand and identity. This is particularly beneficial in companies with distinctive cultures or loyal brand followings. ### Scenario 5: Family-owned or founder-led transitions Founder CEO transitions are [2-3 times more likely to fail](https://hbr.org/2026/01/leading-after-the-founder) or result in a performance downturn, while [two-thirds of family-owned businesses](https://www.mckinsey.com/industries/private-capital/our-insights/passing-the-baton-creating-value-through-ceo-succession-at-family-businesses) see a decline in revenue growth after transitions. However, when done well, [family-to-family CEO transitions are more successful](https://www.mckinsey.com/industries/private-capital/our-insights/passing-the-baton-creating-value-through-ceo-succession-at-family-businesses) than non-family transitions. With the right preparation, internal successors drive the best value creation while maintaining a connection to heritage. ### Scenario 6: High stakeholder trust in existing leadership When boards trust the executive team, they can minimise transition risks by hiring internally. The opportunity for trust building should come through the CEO development program. ### Scenario 7: Balancing leadership team composition If an external candidate has been appointed as board chair recently, the board should select an internal CEO. This avoids the risk of changing both key leadership roles at once, minimises disruption and preserves organisational knowledge. ### Scenario 8: Risk-averse governance and conservative stakeholders Internal CEOs represent a known and proven choice and can signal organisational health. This can appeal to boards during economic uncertainty or in risk-averse governance contexts. One of the most common reasons boards recruit externally is a lack of internal options, which is why it’s good practice for boards to make succession planning a board priority. Even with an effective development program in place, it can take up to two years to develop the skills for the CEO role. By maintaining a range of ‘ready now’ candidates, the board will always be in the best position for a planned or unforeseen CEO transition. Yet even with a strong internal bench, there are some strategic reasons why an outsider could be an advantage. PART THREE ## Commercial scenarios favouring external CEO succession ![Gold line icon of a globe with a magnifying glass focusing on part of the world, representing external executive search.](https://sterlingblack.com/hs-fs/hubfs/chapter-3-icon.png?width=155&height=155&name=chapter-3-icon.png "Gold line icon of a globe with a magnifying glass focusing on part of the world, representing external executive search.") Here are six reasons why a board should consider hiring an external CEO: ### Scenario 1: Turnaround or crisis situations External CEOs can offer unbiased leadership and make difficult decisions in tough times. The board may also look for an outsider with proven skills in turnaround or crisis scenarios. ### Scenario 2: Stagnant performance or cultural complacency Outsiders bring a fresh perspective to entrenched business models or cultures. They can be a catalyst for reinvention when faced with declining growth or a need for change. ### Scenario 3: Board management conflict or governance reset When a company has faced governance issues, an external CEO can renew trust or authority. This is especially relevant after proxy battles, shareholder revolts or board disputes. It may also be needed after a broader loss of faith in the management team ### Scenario 4: Strategic transformation or repositioning Boards may hire outside the organisation when they need specialised skills or experience. This includes navigating new markets, business models or emerging technologies. An outsider can also symbolise change when public companies need a perception reset. For example, when seeking re-rating, post-IPO repositioning or recovering from sustained underperformance. ### Scenario 5: Succession from a dominant CEO Insiders can be a sign of continuity and trust when replacing a founder or iconic CEO. However, they may also struggle to follow them if the former CEO hasn't created an environment for strong leadership to flourish. In this case, an outsider can signal the start of a new era, offering a credible break to  stakeholders. ### Scenario 6: Diversity or cultural transformation mandates External CEOs can diversify or modernise thinking in leadership teams that have become too similar. Boards can also hire outsiders to signal a genuine commitment to workplace change. ### Conclusion The data makes a strong case for internal succession – internal CEOs typically stay longer and perform better. Yet boards are increasingly looking to external candidates. In some cases, this may be purely the result of the board not implementing an effective CEO succession process. While every succession event is different, the internal vs external CEO debate is only a real question when boards have planned for succession well. Without a CEO development pipeline producing ready candidates, the choice is made by default instead of strategy. Boards that invest in CEO succession consistently are the ones with genuine internal options when it counts. PART FOUR ## Internal vs external CEO succession decision framework ![Gold line icon of a grid chart with a check mark and an X in separate boxes, representing a decision matrix.](https://sterlingblack.com/hs-fs/hubfs/chapter-4-icon.png?width=155&height=155&name=chapter-4-icon.png "Gold line icon of a grid chart with a check mark and an X in separate boxes, representing a decision matrix.") Rather than relying on instinct or precedent, this decision framework uses screening questions and a weighted scoring matrix to assess the context of an organisation and identify whether an internal or external CEO is the stronger strategic fit. 1 Screening Questions Answer these first. A yes to any question is a strong indicator of the direction you should head in. Otherwise, move onto the scoring matrix. Is the company in financial or reputational crisis? External indicator Strong indicator for **external CEO**. External candidates bring unbiased leadership and the credibility to make difficult decisions in a turnaround or crisis context. Has there been a governance breakdown — proxy battle, shareholder revolt, board dispute or a broader loss of faith in management? External indicator Strong indicator for **external CEO**. An outsider can renew trust and authority after governance failures, signalling a credible reset to stakeholders. Has an external candidate been appointed as board chair in the past year? Internal indicator Strong indicator for **internal CEO**. Changing both key leadership roles at once creates unnecessary disruption and dilutes organisational knowledge at a critical moment. 2 Scoring Matrix Select all scenarios that apply to your organisation.
