How Functional C-Suite Roles Are Changing

January 8, 2026 – Functional C-suite roles are being reshaped by rising complexity, pushing companies to build leadership teams that are not only individually strong but strategically integrated across the enterprise. Spencer Stuart has long tracked the evolution of key functional C-suite roles as part of its client work. Specifically, the firm found that senior functional roles have become more strategic and enterprise-focused as the challenges facing businesses have become increasingly complex.

It is more important than ever not only to have the right people in these critical leadership roles, but also for the CEO’s team to be aligned and collaborative rather than just a collection of talented leaders. Spencer Stuart mapped the profiles of executives in the nine most common functional leadership roles in S&P 500 C-suites, looking at tenure, career backgrounds and personal characteristics.

Here are a few observations from this year’s analysis:

Most S&P 500 C-suite leaders, 59 percent, were promoted from inside their company. Chief operating officers and CEOs were most likely to be insiders, with 80 percent of COOs and 76 percent of CEOs promoted from within their companies. Conversely, top leaders in communications, information technology and legal were most likely to be external hires, with 57 percent, 54 percent and 53 percent hired from outside the company, respectively, for those roles.

“Larger companies and those with more business units can have an advantage in leadership development, as they typically have more functional management roles to develop and test high-potential leaders, giving them more internal options when the time comes,” the Spencer Stuart report said. “Hiring external talent can allow companies to level up expertise in highly specialized areas like technology.”

Spencer Stuart also found differences across industry sectors. C-suite leaders in the industrial and consumer sectors were most likely to be insiders (61 percent and 62 percent, respectively), compared to 56 percent of C-suite leaders in healthcare and technology, the sectors with the lowest share of internally appointed leaders.

When companies do look externally for leadership talent, there are different expectations about the need for industry expertise, depending on the role, the Spencer Stuart report found. Sector experience appears to be most important for CEOs and COOs, with less than 20 percent of external hires coming from outside companies’ respective industry sectors. By contrast, more than half of externally hired chief information officers (52 percent) and chief communications officers (53 percent) came from another industry. In both cases, newly hired leaders were more likely to come from the tech sector than other industries. Consumer companies were most likely to look outside the sector when hiring external leaders. Executives from outside consumer accounted for 44 percent of external appointments, versus the 42 percent average for all sectors. Consumer companies were most likely to hire from outside the industry for COOs, CFOs and general counsel.

Spencer Stuart also sees variance in the preference for prior experience across functional roles: more than 40 percent of CHROs, CIOs and chief legal officers previously served in the role, compared with 33 percent of functional leaders overall. Just 16 percent of CEOs and 12 percent of COOs have had prior experience in the role. While, overall, CEOs are less likely than most C-suite leaders to have prior experience, Spencer Stuart’s research shows a growing preference among boards for CEOs with previous public company CEO experience.

Backgrounds

Longest Tenures

The study found that the average tenure of sitting S&P 500 C-suite leaders is 5.2 years. C-suite leaders in financial services collectively serve almost a year longer on average, while consumer C-suite leaders about a half year less.

CEOs have the longest average tenure, at 7.6 years, three years longer than the 4.7-year average of all other C-suite leaders. Chief legal officers have the next longest average tenure at 6.1 years. In two sectors — consumer and industrial — the average tenure of the chief legal officer is longer than the average CEO tenure, largely due to the share of legal officers with a tenure of 10 or more years.

COOs have the shortest tenure, averaging 3.3 years — likely because the role often is meant to be a temporary development position for CEO aspirants — followed by CMOs at 4.1 years.

Average Tenure By Industry and Role

Fifteen percent of S&P 500 C-suite functional leaders took their roles within the past year. About one-quarter of COOs are in their first year, compared with just 10 percent of chief supply chain officers.

Newly Appointed C-Suite Leaders

Women and Ethnically Diverse Leaders

Overall, Spencer Stuart found that 43 percent of S&P 500 C-suite roles are held by women and people from historically underrepresented ethnic and racial groups. Representation varies widely by role; fewer than one-quarter of CEOs and COOs have these backgrounds, compared with 78 percent of CHROs and 70 percent of chief communications officers.

Digging deeper, 35 percent of functional C-suite roles are held by women and 13 percent by leaders from historically underrepresented ethnic and racial groups. Women are most likely to hold chief HR, communications and marketing roles. CIOs as a group are the most ethnically diverse.

Looking across sectors, healthcare has the highest percentage of women in the C-suite (40 percent). At 27 percent, healthcare also has the highest percentage of female COOs, an important steppingstone to the CEO role, followed by financial services at 20 percent. The industrial and technology sectors have the lowest share of women in the C-suite, 32 percent and 33 percent, respectively. However, the technology sector has the highest percentage of ethnically diverse leaders, and 26 percent of technology company CEOs are from historically underrepresented ethnic groups.
