Inmarsat Investments Limited (a subsidiary of Inmarsat plc) establishes US$550 million syndicated credit facility

Inmarsat Investments Limited (a subsidiary of Inmarsat plc) is pleased to announce the successful completion and signing yesterday of a new $550m syndicated credit facility led by Joint Bookrunners and Mandated Lead Arrangers Barclays Capital (the Investment Banking Division of Barclays Bank PLC), ING Bank N.V. and The Royal Bank of Scotland plc. The facility is for general corporate purposes including refinancing existing debt, and was arranged in connection with Inmarsat plc’s recently announced listing on the London Stock Exchange (LSE:ISAT).

The $550m five-year financing is split between a $250m amortising term loan and a $300m revolving credit facility. The term loan and drawings under the revolving credit facility are initially priced at 120bp above Libor and thereafter tied to a leveraged grid.

The transaction was syndicated on a targeted basis among the company’s core relationship banks and despite being oversubscribed was not increased above the $550m initially sought. In addition to the three Mandated Lead Arrangers there are nine Joint Lead Arrangers all of whom were lenders to Inmarsat Investments Limited in the previous syndicated credit facility.

Headquartered in London, Inmarsat is the leading provider of global mobile satellite communications services, providing data and voice connectivity to end-users worldwide. Inmarsat has more than twenty-five years of experience in designing, launching and operating its satellite-based network. With a fleet of ten owned and operated geostationary satellites, Inmarsat provides a wide range of data and voice services, including telephony, fax, video, email and high-speed intranet and internet access. Inmarsat’s revenues, operating profit and EBITDA under UK GAAP for the full year 2004 were US$480.7 million, US$159.1 million and US$303.6 million, respectively.
