Arcadis Names National Grid Executive to Board as Leadership Transitions Unfold

Arcadis has announced the nomination of Carl Trowell, President of Strategic Infrastructure at National Grid PLC, to its Supervisory Board, marking a significant leadership move for the Dutch design and consulting firm. Trowell's appointment, subject to shareholder approval at the company's Annual General Meeting on May 20, 2026, comes as Arcadis undergoes notable governance changes, with current board chair Michiel Lap retiring after 11 years of service and Peter de Wit positioned to assume the chairmanship.

Strengthening Infrastructure Expertise

Trowell brings over 30 years of experience in energy and infrastructure projects to Arcadis, a global leader in designing and consulting services for natural and built assets. His tenure at National Grid PLC, one of Europe's largest utility companies, positions him as an invaluable addition to the board as Arcadis continues to navigate the complex intersection of energy transition, infrastructure modernization, and climate resilience.

The appointment reflects Arcadis' strategic focus on expanding its depth in critical infrastructure sectors. With Trowell's background spanning multiple decades of large-scale energy and infrastructure initiatives, his presence on the Supervisory Board is expected to strengthen the company's advisory capabilities in these sectors. The nomination underscores the growing importance of infrastructure expertise in an era where governments and enterprises are substantially increasing investments in grid modernization, renewable energy integration, and climate adaptation.

Governance Transition and Board Continuity

The nomination occurs alongside planned governance transitions that will shape Arcadis' leadership trajectory. Michiel Lap's retirement after more than a decade as chair represents a significant generational shift, while Peter de Wit's ascension to the chairmanship provides continuity in the company's strategic direction. The staggered approach to leadership transitions—with Trowell's four-year term beginning at the 2026 AGM—demonstrates deliberate succession planning aimed at maintaining board stability and institutional knowledge.

Trowell's appointment would expand the board's bench strength during a period of substantial change in the utilities and infrastructure sectors:

• 30+ years of relevant industry experience
• Strategic focus on infrastructure and energy transition initiatives
• Direct exposure to large-scale grid modernization projects
• International perspective gained through work at a multinational utility

Market Context: Infrastructure and Energy Transition Megatrends

The timing of Trowell's nomination reflects broader market dynamics reshaping the infrastructure and consulting landscape. Global governments are committing unprecedented capital to infrastructure development, renewable energy deployment, and grid modernization—creating significant demand for advisory and design services. The European Union's green taxonomy, national net-zero commitments, and post-pandemic infrastructure stimulus have positioned infrastructure consulting firms at the center of the energy transition narrative.

Arcadis, operating in this favorable market environment, competes with other major engineering and consulting firms that are similarly expanding their energy and infrastructure capabilities. The company's ability to attract experienced executives from leading utilities like National Grid PLC signals confidence from the market and reflects the growing cachet of infrastructure consulting in the transition economy.

The energy sector, specifically, is experiencing accelerating transformation. Utilities face mounting pressure to modernize aging grid infrastructure while simultaneously integrating distributed renewable resources and managing demand-side management programs. This creates a decade-long wave of consulting and design work—exactly where Arcadis positions its capabilities. Trowell's direct experience navigating these challenges at National Grid, one of Europe's most complex utility networks, makes him exceptionally qualified to guide Arcadis through continued industry evolution.

Investor Implications: Strengthened Strategic Direction

For shareholders, Trowell's appointment signals Arcadis' confidence in its market positioning and strategic direction within high-growth infrastructure segments. The addition of proven executive talent from a peer organization enhances the board's ability to identify emerging opportunities and navigate regulatory challenges in energy and infrastructure markets.

The governance transition also matters for investors monitoring board composition and leadership stability. The planned retirement of a long-serving chair after 11 years follows best practices around board tenure and refresh cycles, while the succession plan with Peter de Wit demonstrates continuity in strategic vision. This measured approach typically resonates positively with institutional investors focused on corporate governance quality.

For equity holders in Arcadis, board appointments with deep sector expertise often correlate with improved strategic capital allocation and enhanced growth prospects in relevant market segments. Trowell's appointment suggests management confidence in the company's infrastructure-focused strategy, particularly as governments worldwide accelerate infrastructure spending.

Looking Ahead

As Arcadis continues to position itself as a premier partner for infrastructure transformation, the addition of Trowell to its Supervisory Board represents a strategic enhancement of governance and advisory capabilities. The nomination will face shareholder scrutiny at the May 20, 2026 AGM, but given his industry standing and relevant experience, approval appears likely. His four-year tenure would coincide with a critical period in the global energy transition, during which infrastructure consulting demand is expected to remain robust. Together with Peter de Wit's transition to chair, these leadership moves position Arcadis to capitalize on sustained infrastructure investment cycles while maintaining governance practices that align with investor expectations for board quality and strategic foresight.
