BRUSSELS — Corporate governance in Belgium is undergoing a quiet yet profound transformation. As economic headwinds, regulatory shifts, and accelerating digital and sustainable demands place unprecedented pressure on corporate leadership, the composition of the nation’s top boardrooms is shifting to meet these challenges. These findings form the core of the newly released 12th edition of the Belgium Spencer Stuart Board Index. This benchmark annual report offers an exhaustive analysis of board governance practices across the 45 major publicly traded companies comprising Belgium’s Bel 20 and Bel Mid indices. Covering the 2024–2025 period, the latest index provides a comprehensive health check of Belgian boardrooms, highlighting critical trends in board renewal, gender and international diversity, director independence, and time commitments. As Belgian companies navigate a complex macroeconomic landscape—marked by shifting geopolitical dynamics, supply chain realignments, and rigorous European Union sustainability reporting mandates—the makeup of the boardroom has never been more critical. The 2025 Spencer Stuart Board Index serves not only as a rearview mirror of corporate trends but also as a forward-looking compass for chairs, chief executive officers, and governance professionals aiming to future-proof their organizations. Main Facts The 12th edition of the Belgium Spencer Stuart Board Index evaluates the governance structures, demographic profiles, and compensation frameworks of the 45 companies listed on the Bel 20 (Belgium’s benchmark blue-chip index) and the Bel Mid (representing mid-cap enterprises). At its core, the report tracks several fundamental metrics that define modern Belgian corporate governance: Scope of Analysis: 45 leading Belgian listed companies across diverse sectors, including finance, biopharmaceuticals, chemicals, industrials, and technology. Core Themes: Board renewal rates, demographic and international diversity, director tenure and independence, and committee structures. The Governance Climate: Belgian boardrooms are increasingly balancing the demands of regulatory compliance—such as the EU Corporate Sustainability Reporting Directive (CSRD)—with the need for agile, globally minded, and digitally savvy leadership.

Chronology: The Evolution of Belgian Governance To understand where Belgian corporate governance stands in 2025, it is necessary to examine the trajectory that has brought the country’s boardrooms to this juncture. The Foundation Years (Early 2010s) When Spencer Stuart first began publishing its comprehensive board index for Belgium over a decade ago, the corporate landscape looked markedly different. Boardrooms were predominantly homogeneous, largely local in composition, and characterized by long-standing, entrenched tenures. Independence was frequently interpreted through a narrow lens, and gender diversity on boards was low, prompting early discussions regarding the necessity of quotas and voluntary self-regulation. The Legislative Push and Cultural Shift (Mid-to-Late 2010s) The introduction of strict gender diversity quotas for state-owned enterprises and listed companies served as a watershed moment for Belgian boardrooms. Over a period of several years, boards began actively hunting for qualified female directors. This era marked the beginning of a structural shift: boards transitioned from closed networks where seats were often filled via traditional "old boy" referral systems to rigorous, competency-based search processes. Post-Pandemic Realities and Stakeholder Capitalism (2020–2023) The COVID-19 pandemic, followed by acute geopolitical instability in Europe and rampant inflation, fundamentally altered the mandate of the corporate board. No longer viewed simply as compliance and oversight bodies, boards were forced to become strategic partners to executive management. Issues such as cybersecurity, supply chain resilience, and environmental, social, and governance (ESG) oversight surged to the top of the boardroom agenda. The Spencer Stuart Board Indices during these years documented steady incremental gains in international representation and a gradual reduction in average tenure lengths as boards sought fresh perspectives to manage disruption. The 2024–2025 Landscape: Institutionalizing Agility The latest edition of the index captures a period of consolidation and institutionalization. Belgian companies are no longer reacting simply to immediate crises; they are embedding structural agility into their governance DNA. The 2024–2025 period reflects a mature corporate ecosystem where diversity is treated not as a tick-box compliance exercise, but as an operational necessity for risk management and innovation. Supporting Data: Dissecting the Numbers The value of the Belgium Spencer Stuart Board Index lies in its rigorous quantitative analysis. While the qualitative shifts in boardroom culture are notable, the underlying data provides an unvarnished look at how Belgian companies operate. Board Composition and Size Belgian boards continue to maintain a balanced size, carefully calibrated to ensure effective dialogue without becoming unwieldy. Across the Bel 20 and Bel Mid indices, board sizes generally hover between 8 and 12 members. This scale allows for adequate representation across key committees—audit, remuneration, and nomination—while ensuring that every director can actively contribute to strategic deliberations. Renewal and Tenure Board renewal is a critical metric for preventing stagnation and ensuring that expertise aligns with changing business models. The 2025 data reveals a deliberate effort by nomination committees to manage tenure: Controlled Tenures: While institutional knowledge remains prized, the era of indefinite directorships is largely over. Average tenures are seeing healthy downward pressure as companies introduce term limits and robust board evaluation processes. Staggered Appointments: To prevent institutional memory loss during periods of transition, most Belgian companies utilize staggered appointment schedules, ensuring continuity while opening the door to fresh faces. Independence Independent directors form the bedrock of shareholder protection and objective oversight in Belgian governance. The latest index highlights a strong commitment to maintaining a robust majority of independent directors across both large- and mid-cap firms. This independence is particularly crucial as boards navigate complex remuneration packages, related-party transactions, and rigorous audit requirements. Diversity Metrics Diversity within Belgian boardrooms continues to evolve across multiple dimensions: Gender Diversity: Building upon years of regulatory progress, Belgian listed companies maintain strong representation of women in the boardroom, comfortably outperforming historical averages and positioning Belgium favorably within the broader European context. International Representation: Given the export-driven nature of the Belgian economy, international diversity is a growing priority. Boards are increasingly seeking directors with cross-border operating experience, particularly in North American and Asian markets, to guide multinational expansion. Functional Expertise: The profile of the modern Belgian director is shifting. While financial and legal expertise remain mandatory, boards are actively recruiting individuals with backgrounds in digital transformation, artificial intelligence, cyber-risk management, and sustainability/ESG frameworks. Official Responses and Industry Perspectives The release of the 12th edition of the Belgium Spencer Stuart Board Index has drawn commentary from corporate governance experts, institutional investors, and boardroom leaders across Europe. The Search and Advisory Perspective Senior leadership consultants at Spencer Stuart emphasize that the role of the non-executive director has fundamentally changed over the past five years. "Today’s Belgian boardroom is unrecognizable compared to a decade ago," notes a senior governance practice leader. "Directors are no longer expected to simply show up four times a year to rubber-stamp management proposals. They are active, engaged, and frequently challenged by complex, fast-moving risks. The data in our 12th edition shows that Belgian companies recognize this reality. They are actively seeking out directors who bring not only traditional financial acumen but also deep expertise in technology, sustainability, and international market dynamics." The Institutional Investor Viewpoint Institutional investors have welcomed the transparency provided by the index. Speaking anonymously regarding broader market trends, a portfolio manager based in Brussels noted that governance quality is now a primary filter for capital allocation. "When we evaluate a Bel 20 or Bel Mid company, the board is our ultimate line of defense and our primary partner in long-term value creation," the investor stated. "Reports like the Spencer Stuart Board Index give us the granular data we need to assess whether a board is truly independent, whether its renewal processes are functioning, and whether it has the right mix of skills to steer the company through structural transitions like the green transition and digitalization." Corporate Chairs and Executives Reactions from boardroom chairs echo the sentiment that governance is becoming increasingly demanding. With the implementation of EU directives on corporate sustainability and enhanced due diligence, chairs report spending significantly more time on committee work, particularly within audit and newly formed or elevated sustainability committees. Implications: The Future of Belgian Corporate Governance The data and trends documented in the 12th Belgium Spencer Stuart Board Index carry profound implications for the future trajectory of Belgian corporate leadership. As companies look toward the remainder of the decade, several key challenges and opportunities stand out: 1. The Proliferation of Specialized Board Committees As the scope of directorial oversight expands, the traditional triad of audit, remuneration, and nomination committees is being strained. Many Belgian companies are expanding their committee structures—or embedding specific mandates within existing ones—to deal explicitly with sustainability, technology, and cybersecurity. The implication is clear: board service requires a greater time commitment than ever before, raising questions about overboarding and director availability. 2. Balancing Local Roots with Global Vision Belgian businesses occupy a unique position at the heart of Europe. However, many Bel Mid and Bel 20 companies operate on a global stage. Boards must strike a delicate balance: maintaining deep roots and understanding within the domestic Belgian and European regulatory environment while incorporating global perspectives that can unlock growth in international markets. The index suggests that while progress is being made on international diversity, there is still room for acceleration. 3. Generational and Skill-Set Renewal The rapid pace of technological change—typified by the generative AI revolution and sophisticated cyber threats—means that historical board profiles can quickly become obsolete. Nomination committees face the ongoing challenge of refreshing boards with younger, digitally fluent directors without sacrificing the strategic wisdom that comes with seasoned executive experience. 4. Navigating the Regulatory Tsunami European regulation is expanding rapidly. From the Corporate Sustainability Reporting Directive (CSRD) to the Corporate Sustainability Due Diligence Directive (CSDDD), Belgian boards are facing an unprecedented volume of compliance and reporting obligations. The modern director must possess the analytical capability to digest complex regulatory frameworks while ensuring that compliance does not crowd out entrepreneurial strategy. Conclusion The 12th edition of the Belgium Spencer Stuart Board Index confirms that Belgian corporate governance is resilient, dynamic, and progressively adapting to a volatile world. By examining the cold, hard data of board composition, tenure, independence, and diversity, the report offers an indispensable mirror to the nation’s corporate leaders. As Bel 20 and Bel Mid companies chart their courses through 2025 and beyond, the insights provided by Spencer Stuart will undoubtedly serve as an essential benchmark. For investors, regulators, and directors alike, the message is unmistakable: effective governance is not a static destination, but a continuous journey of renewal, diversification, and strategic foresight.
