“We thank Greenhill for their years of support as important stakeholders and senior leaders on our Board,” said Matt Desch, CEO, Iridium. “We appreciate that Greenhill is selling its stake in Iridium in a measured and thoughtful way, with a view to minimizing the potential impact of their share sales on our day-to-day trading activity.”

Desch continued, “We’re also grateful that Scott Bok, CEO of Greenhill, will continue to be a significant stockholder personally and serve as a member of our Board.”

“We continue to believe strongly in the value of Iridium as a global communications company,” said Scott Bok, CEO, Greenhill. “We’ve made the decision today to sell our stake in Iridium primarily to fund the repurchase of Greenhill’s own attractively valued common stock, and we believe that implementing a long-term 10b5-1 plan will allow us to participate in the full value of Iridium being reflected in its share price over time.”
