Commenting on these changes, Iridium CEO Matt Desch shared, “I’m expecting a seamless leadership transition with the appointment of Vince and Tim to the executive team. It is a credit to both Tom Fitzpatrick and Bryan Hartin that they have developed leaders on their teams with the experience and vision to successfully succeed them. Both Vince and Tim have extensive experience working with Iridium’s partners, employees and investors and will continue the success of their predecessors.”

Speaking specifically to the retirements, Desch continued, “Tom has led Iridium through obtaining export credit financing of the largest-ever satellite constellation refresh, multiple capital market offerings and a strong credit facility with attractive terms, while leading the financial transformation of a company which, by the time of his retirement, is expected to have returned approximately $1.0 billion to shareholders over the previous three years. We are also very fortunate that he will continue to provide strategic leadership and his experience as a continued member of our Board.” As to Hartin, Desch commented, “Iridium is defined by its products and its partners. Bryan has successfully overseen the expansion of our commercial business as service revenues grew by 126% since he joined and subscribers almost quadrupled while he led our partner ecosystem growth to over 500 companies.”

It has been a privilege to play a part in the success of this unique, essential organization. I thank Matt and the Iridium Board for their consistent support during my time at the company,” said Fitzpatrick. “I am delighted to remain involved in Iridium’s strategic direction through my service on the Board. I look forward to continuing to work on our important mission in this role.”
