I look forward to continuing to work closely with Gregg in his new role, and I am confident that he will continue Ken’s legacy of integrity and strong leadership in the CFO position. On behalf of all of us at DST, we thank Ken for his nearly three decades of service and wish him all the best in his retirement.”
