The 2026 South Africa Spencer Stuart Board Index analyses board composition, committees, director remuneration and other aspects of board governance among the top 50 companies listed on the Johannesburg Stock Exchange (JSE).
Our analysis has found that board size has remained broadly stable, while independent oversight and representation have strengthened. Rather than pursuing wholesale change, boards are balancing continuity and institutional knowledge with selective renewal designed to meet increasingly complex economic, technological and regulatory demands.
Independent directors now account for 87% of non-executive directors, while HDSA (Historically Disadvantaged South African) representation has risen to 35.2% of board seats and women hold 38.5%. Yet representation at CEO and chair level continues to lag, underlining the need for succession planning and director development that convert broader participation into leadership opportunities.
87%
of non-executive directors are independent, up from 83% in 2024
35.2%
of board seats are held by HDSA directors, up from 32.4% in 2024
38.5%
of board seats are held by women, compared with 37% previously
23%
of newly appointed directors are serving on a public-company board for the first time
30%
of new appointments are international directors
50%
of companies use externally facilitated board evaluations, up from 44% previously
The next phase of progress is likely to depend less on adding seats and more on how deliberate boards use succession, evaluation and director development to strengthen future readiness.
Composition, independence and representation remain important, but the connecting question is whether the board as a whole has the judgement, leadership pathways and future-facing capabilities required to oversee strategy, risk and transformation in markets that are increasingly complex and evolving rapidly. Further, with the increasing diversity of age, ethnicity experience and skillsets, the role of the Chair may be shifting from managing boardroom process to actively managing contribution and boardroom dynamics.
