Tjeerd Bosklopper to succeed David Knibbe as CEO of NN Group. Today, NN Group announces that its Supervisory Board intends to appoint Tjeerd Bosklopper as CEO of the company. Tjeerd, who is currently CEO of NN Netherlands Non-life, Bank & Technology, will succeed David Knibbe, who will step down from NN Group as of 1 March 2027 to pursue an opportunity outside the company. The appointment of Tjeerd has been approved by the Dutch Central Bank and will be effective after notification to the General Meeting of NN Group at the annual general meeting (AGM), to be held on 12 May 2027. To ensure continuity and in line with NN Group's articles of association, the Supervisory Board has designated Tjeerd as CEO-designate to occupy the vacant seat on the Executive Board from 1 March 2027 until his appointment takes effect. Tjeerd was appointed to the Management Board of NN Group in September 2018. In his current role, he is responsible for the Dutch non-life and banking businesses and technology. Since 2024, he oversaw the introduction and implementation of Future Ready, a company-wide digital transformation programme. In previous roles, he held various leadership positions across NN and ING, both in the Netherlands and internationally. He started his career as a global management trainee at ING. David Cole, chair of the Supervisory Board of NN Group: 'With the intended appointment of Tjeerd Bosklopper, we have found an excellent successor from within the company. Tjeerd has a deep understanding of our businesses, culture, stakeholders, and the wider industry. With his international experience and strong track record in executing transformations, we are confident he can lead NN in a time of rapid technological and societal developments, creating opportunities for future success. We wish him all the best in this new role.' 'We would also like to thank David Knibbe for his inspiring leadership, resulting in the strong and diversified company of today. Together with his team, David oversaw a successful transformation of NN into a growing company with leading market positions and an expanding international footprint, while maintaining a strong commercial and financial performance. David championed an approach that looks beyond short-term results, creating sustainable long-term value for customers, colleagues and society. On behalf of the Supervisory Board, the Management Board and all NN Group employees, I want to thank David for his contribution to NN throughout his nearly 30-year career at the company. We wish him all the best in the future.' Tjeerd Bosklopper: 'It is an honour to have been offered the opportunity to be NN Group's next CEO, and I am excited about what lies ahead. I'm very much looking forward to working with colleagues across NN, building on the strong foundation established under David's leadership and shaping the next chapter of NN together. I am grateful to David for all he has contributed, and I wish him all the very best for what comes next.' David Knibbe: 'After almost 30 years with NN and its predecessor organisations, this is a special moment for me. I am proud of what we have achieved together by focusing on our customers, our great talent base, and by playing a positive role in society. We have transformed NN into a growing company that has delivered strong financial results, and I feel especially fortunate to have worked with many talented colleagues. NN is in a strong position today, reflecting the progress we have made across the company. This is the right moment for me to move on to a new challenge, after serving 13 years in the Management Board and nearly 8 years as CEO. I am particularly pleased that Tjeerd, who I have worked alongside for more than 20 years, is intended to succeed me. I would like to congratulate him and wish him, all our colleagues, and NN every success for the future.' The Central Works Council of NN Group has provided a positive advice on the intended appointment.
