According to a new Spencer Stuart report, S&P 500 boards added new directors at the slowest rate in a decade. The report also says that newly appointed directors are older, less diverse, and more likely to come from the ranks of CEOs than in recent years. Here are some of the specific findings:
– S&P 500 boards appointed 364 new independent directors in 2026, out of a total of 5,204 — the lowest number of new directors since 2016. Overall turnover remains low, declining from 0.8 new directors per board last year to 0.7 in 2026.
– This year, 37% of all new directors are CEOs, an increase of seven percentage points from last year. This is the highest share since a peak of 42% in 2012. Overall, 64% of incoming directors bring CEO or financial experience, up from 59% in 2025. Retired individuals again represent the majority of appointments.
– New directors averaged 60.1 years of age, up from 59.1 years in 2025. The youngest new director to join a board in 2026 was 29 years old. The oldest was 77, the same as last year. The average age of sitting independent directors is 63.8. Next-generation (next-gen) new directors (those aged 50 or under) represent 10% of the incoming class, down from 11% in 2025.
– The share of director appointments filled by diverse* executives declined in 2026. Women account for fewer director appointments this year, and the percentage of boards expanding to add one or more women directors is unchanged since last year at 10%. However, the share of new directors who self-identify as underrepresented minorities increased slightly, and more boards have expanded to add one or more directors from this group: 6%, compared with 5% in 2025.
The report also says that fewer first time directors were appointed to public company boards during 2026, and that more companies did not replace directors who left boards. That’s a departure from previous years, where new director appointments generally tracked director departures.

The results of the Spencer Stuart report came as a bit of a surprise to me, particularly since board refreshment is an increasingly important topic – not just to investors, but also to a surprising number of board members. This Debevoise memo has some advice for boards on how to approach the refreshment process. This excerpt says that an effective refreshment strategy starts with succession planning:
Start with Succession Planning. Rather than reacting to vacancies as they arise, boards should establish an ongoing process for evaluating future leadership needs and preparing for expected and unexpected director departures. Responsibility for overseeing succession planning typically rests with the nominating and governance committee, with clearly defined roles for both the full board and management.
Boards should consider making succession planning a recurring agenda item, periodically reviewing anticipated retirements and discussing directors’ longer-term plans. Documented succession procedures help to ensure that transitions occur efficiently and with minimal disruption.
Succession planning also provides an opportunity for boards to look beyond anticipated vacancies and consider what expertise may be needed over the coming years. Regular discussions about future strategies, emerging risks, and changing regulatory expectations help to identify the skills and experiences that would help future directors add value to the boardroom.
Boards should also consider creating a culture of refreshment (even without formal term limits) in which directors understand that after some period of time, it is expected that they will step down to allow for new directors to be added.
Other recommendations include using board evaluations to inform refreshment decisions, periodically assessing whether the board’s composition remains aligned with the company’s strategic priorities and risk profile, and maintaining an active candidate pipeline.

While we’re on the topic of board refreshment, a recent paper says that refreshing your board can pay some significant governance dividends. Here’s an excerpt from a CLS Blue Sky Blog post by the paper’s authors:
Our results suggest that board refreshment is associated with stronger CEO turnover-performance sensitivity. In simpler terms, refreshed boards are more likely to replace the CEO after weak performance.
We also find that refreshment is associated with stronger pay-for-performance sensitivity. CEO wealth becomes more closely tied to stock price performance, and the difference is not trivial: It corresponds to tens of thousands of dollars in additional pay sensitivity for a board that has refreshed more than a typical peer. At the same time, refreshment is positively related to pay-for-risk sensitivity. This balance matters. Compensation should reward performance, but it should also give managers incentives to take appropriate risks rather than avoid valuable long-term projects.
Taken together, the results suggest that refreshed boards do not just look different. They appear to monitor differently. They are associated with stronger CEO dismissal discipline after poor performance and with stronger CEO pay structures that better connect performance and risk.
The authors also suggest that companies that take an active approach to refreshment may be missing an opportunity when it comes to their proxy disclosures, because most disclosures don’t address how the company’s board has evolved.
They argue that these companies should explain in their proxy disclosures the “capabilities, expertise, or perspectives recent appointments added relative to the previous board, and how those changes respond to the firm’s current governance and oversight needs.” The authors believe that disclosure like this would enable investors to distinguish between ordinary director turnover and genuine board renewal.
