Intelsat Announces Retirement of Chief Financial Officer

Jacques Kerrest expected to remain in role throughout search process for successor

Luxembourg, 14 January 2019

Intelsat announced today that its Chief Financial Officer, Jacques Kerrest, plans to retire. He will continue in his role through the spring until a successor is appointed to ensure a smooth transition of duties.

Since joining Intelsat in February 2016, Mr. Kerrest played an instrumental role in successfully completing $15.5 billion in debt and equity transactions, achieving an improved capital structure for the company.

“On behalf of the company and the management team, I’d like to thank Jacques for his leadership and many contributions during his tenure,” said Stephen Spengler, Chief Executive Officer. “Jacques’ expertise in capital markets and strategic engagement with debt and equity investors enhanced Intelsat’s position as a respected issuer. One result of his contributions, our improved capital structure, provides us the flexibility that positions us to execute our business strategies. We wish Jacques well as he pursues his personal goals during his well-earned retirement.”

The company is retaining an executive search firm to lead the search for his replacement.
