As 2025 comes to a close, we want to take a moment to say thank you.
It has been a challenging year for so many, which makes the support, trust and engagement we’ve received all the more meaningful.
Whether you work with us closely or follow our insights from afar, we’re grateful to our clients, partners, colleagues and the wider community who read, challenge and trust our work. Your support means a great deal to us.
2025 has also been a year of planning. Next year, Cullen International will celebrate 40 years, and over recent months we’ve been preparing for that milestone — reflecting on where we started and what we’ve built together.
Looking ahead to 2026 and our 40th anniversary, we’re excited to celebrate together and to continue supporting you through an ever-evolving regulatory landscape.

We’re also grateful for your feedback and thoughtful suggestions. For each piece of client feedback received, a tree was funded — meaning 🌳 2000 trees 🌳 — which will help rebuild Desa’a Forest in Ethiopia, supporting WeForest’s mission to create positive environmental impact.
This also includes trees earned through our colleagues’ efforts, with every kilometre cycled, walked or run during our summer mobility challenge making a difference.

From all of us at Cullen International, we wish you a restful end to the year and a bright start to the one ahead.
Your Cullen International Team
