Record CFO churn, no bench: the succession gap boards are papering

A hiring record built on scarcity, not strength

The S&P 500 drove the surge. A record 106 CFOs were hired across the index in 2025, up from 89 in 2024 - a 19% increase and well above the seven-year average of 86. Australia's ASX 200 moved in the same direction, from 36 appointments in 2024 to 49 in 2025. On its own, that looks like healthy executive mobility in a recovering market.

The gap between appointments and exits complicates the picture. RRA attributes part of the 54-role spread to interim or 'bridge' CFO arrangements, longer handover periods, and expanded finance leadership structures stood up before a permanent appointment lands. In other words, some companies are counting two finance leaders at once because they could not go directly from one to the next. A widening appointment-departure gap, the firm notes, can signal limited succession optionality - the polite phrase for having nobody ready.

Tenure data points the same way. Average outgoing CFO tenure across the FTSE 100 fell to 5.0 years in 2025, a seven-year low, down from 5.3 in 2024 and well below the seven-year average of 6.8. Shorter tenures compress the window in which a sitting CFO can develop a credible internal successor - and shorten the runway for that successor to be seen by the board.

The bench problem, quantified

Only 16% of CFOs believe their organization has a proactive succession plan in place. That figure is the load-bearing statistic in this story, because it explains why a record hiring year produced so much interim leadership rather than smooth internal handoffs.

The external-hire share confirms it. Nearly half of FTSE 100 CFO appointments in 2025 came from outside the organization - a materially higher external share than for CEO roles in the same index. Boards, in general, prefer to promote CEOs from within; that they do not do the same for finance says something about the depth of the finance pipeline rather than about board preference. First-time CFOs still accounted for 57% of global appointments, meaning more than half of newly seated finance chiefs are learning the public-company reporting cycle, the analyst call and the audit committee relationship simultaneously.

Retirement is accelerating the churn on the way out. In the U.S., roughly half of exiting CFOs retired in 2024, rising to about 62% in 2025 - supported by strong equity markets and a preference for planned exits. Globally, six in 10 departing CFOs retired or moved to a board-only role, nearly twice the 2019 share. Retirements are, in principle, the most forecastable form of turnover. That so many still produced external searches suggests the forecast was not acted on.

CEO churn and activists reset the CFO seat

Two secondary triggers are compounding the volume. CEO changes in 2025 ran about 21% above the eight-year average, and new CEOs routinely reassess the CFO seat within their first year - either because they want their own finance partner or because the incumbent was a rival candidate. Activist campaigns also rose sharply versus 2024, and activists reliably prompt boards to ask whether the current CFO is the right one for the next chapter, particularly where the thesis involves cost structure, portfolio separation or capital return.

ConocoPhillips illustrates how the two seats interact. The company named CFO Andy O'Brien to succeed Ryan Lance as chief executive, with controller Konnie Haynes-Welsh stepping up as CFO effective Sept. 1, 2026. That is the outcome a well-run pipeline produces: the CFO is promotable, and the controller is ready to backfill on a disclosed date. It is also a reminder that CFO succession is a two-seat problem. Every CFO who is a serious internal CEO candidate creates a vacancy the moment the board acts.

What this means for sitting CFOs

Finance chiefs now sit on both sides of the succession ledger. They are candidates - for the CEO job, for a bigger CFO seat, for a board slate - and they are risks, because an unplanned departure without a ready-now deputy leaves the company in interim leadership through a quarter close, a guidance cycle or an audit. Investors read that as a control question, not a personnel question. It is a credibility event with a cost.

The practical response is to treat the controller and FP&A bench as a board-reportable asset rather than an HR exercise. That means naming, in writing, who covers the seat on day one if the CFO is unavailable; who is the 12-to-24-month internal candidate and what specific gaps - investor relations exposure, treasury, M&A integration, audit committee presence - stand between them and readiness; and what the development plan is against those gaps, with dates. NACD's 2026 board priorities work puts management succession depth firmly among directors' agenda items; CFOs who bring that map to the audit or nominating committee unprompted control the narrative rather than answering it under pressure.

The other implication is defensive. If nearly half of large-cap finance chiefs are being recruited externally and 57% of appointments globally go to first-timers, the market for experienced CFOs is repricing. Retention conversations with a strong controller or divisional CFO should assume they are already receiving calls. Losing the successor is functionally the same as never having had one.
