The following is a transcript of a video clip of an episode of CNBC’s Squawk on the Street television program which aired on April 30, 2018:

JOHN LEGERE: Well, I’ll let Marcelo chime in, but yeah, we’ve been obviously thinking about this for a long time. There’s been gyrations as to, you know, whether it could get through from a price or governance standpoint. But one thing that was never confused, especially with Marcelo and I, is that these two companies made sense together and the 5G aspects that are critical for the country and critical for us really was the flipping point as to this is the time and it makes great sense.

JIM CRAMER: All right. I’m gonna – Marcelo, is my bill gonan go up? I mean, how could it not? Because, in the end, competition – free market competition – brings down prices.

JOHN LEGERE: Ask him who is provider is before you tell him about his bill. His bill is going down because he’s got the Dumb and Dumber.

JIM CRAMER: Which one? You never told me which was dumber.

JOHN LEGERE: AT&T has solidly moved into the dumber role. Solidly. All in. I mean, that egg they laid the other day. Come on. Go ahead, Marcelo.

MARCELO CLAURE: Let me answer that, all right. We’ve been very clear in this merger. What would make this merger unique is we’re set to build the world’s most advanced 5G network and the combination of our companies allow us to do that. And we made a commitment that few people make. That we’re actually going to offer the best product, best services at the lower prices. So, we plan to make this market more competitive. You’ve seen two disruptive companies – T-Mobile and Sprint. Together – you know, if you think we’re disruptive – together we can turbo charge that.

The following is a transcript of a video clip of an episode of KSHB-TV’s “41 Action News Midday” television program which aired on April 30, 2018:

CYNTHIA NEWSOME: 41 Action News reporter Steven Dial talked to those employees. And, Steven, what did they say?

STEVEN DIAL: Cynthia, a lot of them say they saw the writing on the wall and now they’re uncertain about having their job. They say already 500 jobs were cut by Sprint earlier this year and now they’re expecting more. That announcement came by both CEOs on social media yesterday. We spoke with Kansas Governor Jeff Colyer about this merger…this possible merger…he says that he hopes that they continue to keep jobs here in Kansas. According to the CEO for T-Mobile, he says this Sprint campus – which is a very large campus – will serve as a second headquarters. Both CEOs spoke to CNBC this morning. Take a listen.


MARCELO CLAURE: This company is about growth. So, when you bring better products, better prices, more jobs – this is a poster child. This is how every merger should look like. So we feel very confident. You can rest assured that we’ve done a lot of studying before we entered into a transaction like this. We have not talked to the government yet, but we feel quite good that we have a compelling proposition.

STEVEN DIAL: And the government is something that they need. Government approval from the FCC and the judiciary branch to make this all happen. A $26 billion deal. Some have asked about Sprint Center. T-Mobile already has its owned named arena, but that doesn’t mean they can’t have two. This will be a lengthy process. Could take up to a year.

The following is a transcript of a video clip of an episode of CNBC’s Squawk Alley television program which aired on April 30, 2018:

JON FORTT: Bill, your take? It seems like, if the feds don’t like AT&T / Time Warner, they should absolutely hate one like this. But, it’s unique. The wireless market, it’s all national. All these players are competing for almost every customer in the U.S. Is there a way that this works in your mind?

BILL GEORGE: I think there is, Jon. With all due respect to my colleague, uh, two…three and four are very weak players here. And I think by coming together, they can get a lot stronger. Sprint to U.S. base. T-Mobile – the technology and capabilities of the Germans. I think by coming together, it’s going to give Verizon and AT&T a run for their money. And, they need it. Frankly, we need more competition and service in offerings and pricing. They’ve got a virtual duopoly at the top of the market. I’d like to see these companies come together. I hope the anti-trust people approve it. I think never underestimate Masayoshi Son, the owner of SoftBank and the controller of Sprint, and Marcelo Claure. They are fantastic and I think they can team up with T-Mobile and build a great company here. And, I’d love to see a third, tough competitor. I don’t think either one of them is a full competitor today. And, I think it will change the game in very positive ways. And we need it. We need that competition.
