PRI appoints Allen-Ratzlaff as interim CEO

By Miriam Onen

The Principles for Responsible Investment (PRI) has appointed its Cambria Allen-Ratzlaff as interim CEO as David Atkin steps down in December after fours years.

Allen-Ratzlaff is the first female person of colour leading the organisation since it was launched by then UN Secretary General Kofi Annan in 2005. The PRI will continue its “global hunt” for a permanent CEO, it said in a statement, while Atkin continues as an advisor until April 2026 to support the transition process.

Allen-Ratzlaff is currently chief responsible investment ecosystems officer and has been with the PRI for two years. She was previously managing director and head of investor strategies for JUST Capital, a not-for-profit research institution, and has also held senior roles at the UAW Retiree Medical Benefits Trust and State of Connecticut Office of the Treasurer as well as serving on a variety of investor-focused boards and committees, including the U.S. Securities and Exchange Commission’s Investor Advisory Committee and the Council of Institutional Investors.

Allen-Ratzlaff said she is honoured to serve PRI as its 20th anniversary approaches. She noted that “Two decades of progress – and a growing body of rigorous research and market data – show that sustainability-aligned strategies and integration can enhance long-term value and reduce material risks. That evidence base is stronger than ever.”

She added that, “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.”

Reflecting on his time at PRI, Atkin said: “It has been a true honour to serve PRI over the past four years. I’m delighted to see Cambria step into the role of Interim CEO – her leadership, insight, and commitment to our mission make her exceptionally well-placed to guide the organisation through this next chapter. I look forward to supporting her during the transition and am confident PRI will continue to thrive under her stewardship.”
