Private bank J. Safra Sarasin has agreed to acquire the remaining 28.69% stake in Saxo Holding AG from founder Kim Fournais, giving it 100% ownership of the online trading platform.

The Swiss firm acquired a majority position in Saxo last year.

The buyout was triggered by J. Safra Sarasin exercising a call option included in an existing shareholders’ agreement, the bank said in a statement on Monday.

Following the transaction, Saxo Bank will continue to operate as a standalone entity. Fournais will retain his position as chairman of the board of directors.

The transition to full ownership comes as Saxo Bank projects its strongest-ever half-year results for the period ending June 30, 2026, citing an influx of new clients and growth in assets under management.

Jacob J. Safra, chairman of J. Safra Sarasin Group, said the acquisition reflects the group’s long-term perspective and commitment to supporting the platform’s next phase of sustainable growth.

Fournais, who built the digital investment firm over the past three decades, said the deal aligns with the companies’ shared vision and represents the “next natural step in Saxo’s evolution.”
