Dear Stockholder:

We have previously mailed to you proxy materials (including the joint proxy statement/prospectus) in connection with the Special Meeting of Stockholders of Virgin Media Inc. (“VMED” or the “Company”), scheduled to be held on June 4, 2013.

The purpose of this special meeting is to consider and vote upon a proposal to adopt the merger agreement entered into between Liberty Global, Inc. and VMED, and certain other merger-related items. The merger agreement provides for the combination of Liberty Global, Inc. and VMED under a new parent company, to be called Liberty Global plc. In the merger, each outstanding share of VMED common stock will be exchanged for 0.2582 of a class A ordinary share of Liberty Global plc, 0.1928 of a class C ordinary share of Liberty Global plc and $17.50 in cash, without interest.

Before the merger can be completed, the stockholders of VMED must vote to adopt the merger agreement. According to our latest records, we have not received your voting instructions for this important special meeting.

The approval of holders of a majority of the outstanding shares of VMED common stock is required to complete the merger. Failure to vote your shares of common stock or an abstention will have the same effect as voting against the merger. Your vote is extremely important and I urge you to return your proxy for this important meeting .

Additional information about the merger is included in the joint proxy statement/prospectus. A copy of the proxy statement is available at http://investors.virginmedia.com.

On behalf of the VMED Board of Directors, thank you for your cooperation and continued support.
