Boards Perform Better with Diversity, Says Former NDA Chair

Why It Matters

Diverse boards are linked to higher returns and resilience, making gender balance a strategic priority for investors and regulators.

Key Takeaways

• Diverse boards deliver higher financial returns, study shows
• Women leaders urged to mentor next generation
• Rivaz chairs Companies House and Anglian Water
• Board diversity improves risk oversight and decision‑making
• UK regulators push for gender balance on boards

Pulse Analysis

Board composition has moved from a token concern to a measurable driver of corporate value. Multiple studies, including the Credit Suisse Gender 3000 and McKinsey reports, show that firms with at least 30 % women on their boards outperform peers on return on equity and stock price volatility. In the United Kingdom, the 2018 Hampton‑Alexander review set a 35 % gender‑balance target for FTSE 350 boards by 2028, and recent filings indicate progress but still fall short. Investors now routinely score governance on diversity metrics, linking them to risk assessment.

Ros Rivaz, former chair of the Nuclear Decommissioning Authority and current head of Companies House and Anglian Water, reinforces the business case with a cultural call‑to‑action. She argues that senior women must “send the elevator back down,” actively sponsoring and coaching emerging talent to accelerate pipeline diversity. Rivaz points to her own experience navigating male‑dominated sectors, noting that mentorship not only expands the talent pool but also embeds inclusive decision‑making habits that cascade through the organization.

The practical takeaway for boards is clear: prioritize gender balance as a strategic imperative, not a compliance checkbox. Companies can start by setting measurable targets, conducting bias‑free talent reviews, and establishing formal sponsorship programs. As the UK’s Corporate Governance Code tightens expectations and ESG funds allocate capital based on diversity scores, firms that lag risk higher cost of capital and reputational damage. Embracing a diverse board therefore protects shareholders, enhances innovation, and positions firms for sustainable growth in a competitive market.
