Verizon / MCI Transaction


Supporting the Government and National Security


Verizon has committed to investing $2 billion in capital and up to $3.5 billion in total (including integration expenses), to enhance MCI’s network and systems, which are critical components of government communications systems. MCI is a significant provider of advanced data, Internet and voice communications services to federal, state, and local agencies in the U.S. and to government organizations worldwide.


Verizon’s investment to enhance the combined company’s extensive global IP backbone and wholly-owned data network will assure that the company can continue to develop and deliver innovative communications products and services to support our nation’s government agencies, research, and defense.


Serving the Federal Government


National security and defense customers, with a large number of dispersed locations around the globe, will benefit from the creation of a strong and secure nationwide competitor with a greater facilities-based reach.


Security and reliability are the hallmarks of MCI’s extensive IP network and are essential to its federal government customers. For over a decade, government agencies including the U.S. Department of Defense, U.S. State Department, Federal Aviation Administration, United States Congress, and Armed Services have relied heavily on MCI’s proven ability to design and install integrated services to protect, transfer, and deliver some of our nation’s most sensitive and influential information. By using secure international private lines, satellites, managed messaging, and “bandwidth-on-demand” capabilities, MCI offers its customers worldwide reach, unsurpassed reliability, and the highest levels of security.

The combined company will continue as the steward of critical government and security networks, enabling government agencies to remain at the forefront of new communications technology.


Serving State Governments


The Verizon/MCI transaction also will produce significant benefits for state and local governments.


Verizon has extensive local networks and provides innovative wireless and broadband services. MCI has sophisticated IP assets and expertise. The combination of these complementary capabilities will allow the combined company to provide a comprehensive array of communications services to state and local agencies, universities, and quasi-government agencies.


This will improve states’ abilities to deliver electronic government statewide, and enable them to perform functions ranging from renewing driver’s licenses to online tax filing, efficiently and securely.
