Zurich's Clariant Signals Continuity Through Its CFO Transition Process

Zurich-headquartered specialty chemicals company Clariant managed its CFO change as a planned succession rather than a sudden leadership replacement. Bill Collins announced his retirement, and the company appointed Oliver Rittgen as CFO effective August 1, 2025. Clariant also committed to a comprehensive handover process designed to ensure a smooth transition between the outgoing and incoming finance leaders.

Experience Was Preserved During the Handover

Collins had played an important role in Clariant's transformation, including strengthening performance management, developing the finance organization and improving free-cash-flow generation and capital efficiency. By planning the transition while Collins was still involved, Clariant sought to preserve this institutional knowledge rather than creating an abrupt break in its financial strategy.

Rittgen Brings Broad Finance Experience

The incoming CFO brought almost 25 years of senior-management experience at Bayer, including roles as CFO of both Crop Science and Consumer Health. His background covers corporate finance, accounting, controlling, M&A and risk management, giving Clariant a finance leader with experience across large and complex international businesses.

Continuity Matters During Sector Pressure

The transition took place while Clariant was pursuing profitability improvements and cost savings in a challenging specialty-chemicals market. The company had set medium-term targets including 4–6% annual sales growth, a 19–21% EBITDA margin and around 40% free-cash-flow conversion by 2027. Maintaining financial leadership continuity therefore mattered as Clariant continued implementing its transformation agenda.

The Transition Has Now Been Completed

Clariant's 2026 reporting confirms that Rittgen is fully established in the CFO role. He participated in the company's first-quarter and second-quarter 2026 results presentations alongside CEO Conrad Keijzer, showing that the planned succession has moved from transition into normal operating leadership.

The Intelligence Takeaway

Clariant's CFO succession provides a useful example of how companies can manage executive turnover without disrupting financial strategy. By announcing the successor in advance and building a formal handover around an experienced outgoing CFO, Clariant reduced transition risk while bringing in new expertise. The approach highlights why leadership continuity can be particularly valuable when specialty chemical companies are simultaneously managing cost pressure, transformation and demanding financial targets.
