Subject Company: Time Warner Cable Inc.

(Commission File No. 001-33335)

On February 13, 2014, the Chairman and Chief Executive Officer of Time Warner Cable Inc. delivered the following employee communication:

Hello everyone! I’m excited to be here today, to tell you more about the transaction we announced this morning with Comcast. This is truly an historic event for our company. As you know, TWC is a one-of-a-kind asset. And I believe that this transaction recognizes our unique value. It’s a phenomenal deal for our employees, our customers, and our shareholders.

The combined company will be, without question, the pre-eminent cable, telecom and entertainment company in the U.S., and we should all be very proud of the role we have in creating it. The new company will have a nearly national platform with the scale to deliver even more innovative products and outstanding customer experiences. That goes for all customers – residential, business services, and advertising.

I believe there will be a lot of opportunity for Time Warner Cable employees in the combined company. Comcast is a successful, dynamic and exciting company. And I have no doubt it will need talented, dedicated employees to serve its expanded customer base.

This is a large and complex transaction, and there is a lot of work required to get regulatory approvals. We expect to close the deal at the end of the year. In the meantime, I fully intend for us to continue to execute on the plans we’ve put in place. I’m very excited about our recent operating momentum. And we shouldn’t take our foot off the gas. Today’s announcement doesn’t change the fact that we want our customers to trust us to connect them to what matters most. And it doesn’t change our desire to build a culture in which we put customers first, we’re empowered and accountable, we do the right thing, and we’re passionate about winning. Nothing would please me more than to end this year with the company in the best shape it’s ever been in.

I realize you’ve been on a rollercoaster ride for months. The speculation about industry consolidation has been a distraction for everyone, and I recognize that while this transaction is incredibly exciting, the prospect of change can also be


unsettling. I appreciate your patience and the intense focus you’ve maintained, and will continue to maintain, on serving our customers.

Because of you, Time Warner Cable is a great company. And, together, we can make it an even better place to work and to do business with during our remaining time as a stand-alone company and, in the future, as part of Comcast.

Thank you for all you do. I’m proud of your work and proud to be your CEO.
