• Cambria Allen-Ratzlaff, PRI’s Chief Responsible Investment Ecosystems Officer, to assume the interim CEO role on December 1, 2025.
• Outgoing CEO David Atkin to remain as Advisor until April 2026 to ensure continuity.
• Board to continue a global search for a permanent successor amid PRI’s 20th anniversary and evolving global ESG policy landscape.
Leadership Transition at a Defining Moment for Responsible Investment
The Principles for Responsible Investment (PRI) announced that Cambria Allen-Ratzlaff will become Interim Chief Executive Officer effective December 1, 2025, succeeding David Atkin, who concludes a four-year term marked by expansion and strategic recalibration within the world’s largest network of responsible investors.
Allen-Ratzlaff, currently Chief Responsible Investment Ecosystems Officer, brings two decades of experience at the intersection of investment strategy, governance, and policy. Her appointment comes as the PRI approaches its 20th anniversary—an inflection point for both the organisation and the wider ESG investment ecosystem navigating heightened scrutiny and shifting regulatory expectations.
Continuity and Strategic Direction
The appointment reflects a balance of continuity and fresh leadership within the PRI. Having joined in 2023, Allen-Ratzlaff has been central to advancing the PRI’s engagement frameworks and ecosystem-building initiatives designed to align capital markets with long-term sustainability outcomes.
Her tenure at JUST Capital as Managing Director and Head of Investor Strategies, and earlier leadership at the UAW Retiree Medical Benefits Trust and the Connecticut State Treasurer’s Office, underpin a career focused on investor accountability and sustainable value creation. She has also served on the U.S. Securities and Exchange Commission’s Investor Advisory Committee and the Council of Institutional Investors—roles that link policy development directly to investor action.
David Atkin will remain with the PRI until April 2026 as an Advisor to support the leadership transition and sustain organisational momentum. During his time as CEO, Atkin expanded PRI’s signatory base, deepened policy engagement, and steered the body through a volatile regulatory environment that tested investor confidence in ESG frameworks.
Board Confidence in Allen-Ratzlaff’s Stewardship
Conor Kehoe, Chair of the PRI Board, said Atkin’s tenure “strengthened the organisation to serve a recently scaled-up and more diverse signatory base, while navigating a rapidly evolving regulatory and political landscape.”
He described Allen-Ratzlaff as “an exciting leader who already has a strong record of delivering impact,” adding that her experience as a former asset owner gives her “a clear understanding of signatory needs and a strong commitment to addressing them.”
Allen-Ratzlaff will work closely with the PRI’s global executive team and its network of over 5,000 signatories to sustain progress on core initiatives, including responsible investment integration, stewardship accountability, and cross-market policy advocacy.
A Pivotal Phase for the PRI and Global ESG
As ESG frameworks face both maturation and political headwinds, Allen-Ratzlaff’s appointment comes at a time when investor organizations are recalibrating strategies to defend and advance responsible investment principles. Her leadership will shape PRI’s engagement across a spectrum of policy arenas—from sustainable finance disclosure regimes and fiduciary duty debates to stewardship accountability in emerging markets.

“The evidence base for sustainability-aligned investment is stronger than ever,” Allen-Ratzlaff said in a statement. “In this shifting geopolitical environment, we remain committed to supporting our signatories’ work in service of the long-term financial interests of their beneficiaries and clients.”
Atkin described his successor as “exceptionally well-placed to guide the organisation through its next chapter,” citing her “leadership, insight, and commitment to PRI’s mission.”
Global Relevance for Investors
The leadership transition arrives as investors contend with recalibrated ESG disclosure mandates in the EU, U.S., and Asia-Pacific, and with PRI preparing to articulate its “Future of Responsible Investment” agenda into 2030. Allen-Ratzlaff’s mandate will likely involve reinforcing investor confidence in ESG integration as both a financial and governance imperative.
For asset owners and managers across 80+ countries, the announcement offers assurance of stability and strategic continuity at a time when investor coalitions are under pressure to demonstrate measurable sustainability outcomes.
As the PRI enters its third decade, the appointment positions the organization to navigate the next era of responsible investment—one defined less by growth in signatories and more by accountability, policy coherence, and real-world impact.
