T-Mobile and Sprint plead their case as FCC considers landmark merger

By Monica Nickelsburg, GeekWire, June 19, 2018

T-Mobile CEO John Legere believes the future of the American innovation economy comes down to his company’s intended merger with Sprint. At least, that’s the case T-Mobile is making as it seeks regulatory approval from the Federal Communications Commission.

On Tuesday, Sprint and T-Mobile submitted a Public Interest Statement to the FCC arguing that the future of wireless competitiveness depends on the merger going through. The argument centers on 5G, the super fast next-generation wireless technology.

In a blog post tied to the filing, Legere attributed the success of American app-based technology companies to the nation’s competitiveness in 4G wireless technology.

“Uber, Snap, Venmo, Instagram – are all products and businesses built in part on the 4G mobile web,” Legere said in the post. “Analysts estimate this early leadership generated billions in economic value and millions of new jobs here in America. All because the U.S. led with broad 4G LTE. With 5G, the stakes are much higher.”

In addition to 5G, the submission says the merger will allow more Americans to “cut the cord” with traditional broadband providers and will improve connectivity to underserved rural areas. The two wireless carriers also claim that their merger will increase competitiveness in the wireless landscape, allowing the combined company to take on incumbents Verizon and AT&T.

AT&T may have blazed a trail for T-Mobile and Sprint with its recent victory in court. On June 12, a district judge approved AT&T’s $85 billion merger with Time Warner, striking a blow to the Justice Department. The DOJ tried to block the deal, raising anti-competitive issues.

But AT&T’s successful merger doesn’t necessarily mean Sprint and T-Mobile’s efforts to combine will be a slam dunk. The DOJ is reportedly investigating how the deal would affect consumer prices for smaller wireless providers, which sometimes rent wireless access from both companies. A combined company could charge those smaller providers more to use its service, which might eventually impact consumer prices.

In April, T-Mobile and Sprint announced their intention to merge into a $146 billion combined company. If the deal goes through, the combined company will be called T-Mobile with Legere at the helm as CEO. If the companies receive regulatory approval, they expect the merger to close by the first half of 2019.

Should regulators approve T-Mobile and Sprint merger?

By Jeff Kagan, Computerworld, July 2, 2018

So far, thinking of all the pro’s and con’s in the decision to approve the T-Mobile, Sprint merger, there is one over-riding reason to approve. Let me explain.

Something interesting happened when T-Mobile and Sprint filed their intention to merge with the FCC. They said a merger would strengthen them and let them compete head to head with competitors like AT&T Mobility and Verizon Wireless. But wait. I thought they already were successfully competing. So, are they, or aren’t they?

The truth is somewhere in the blurry middle. Over the last five years, both T-Mobile and Sprint have gone through major changes. Five years ago, both of them were smaller and insignificant competitors in the wireless industry.

CEO John Legere saved T-Mobile

Then John Legere was brought in as CEO of T-Mobile and things started to change. When he stepped in, the company was crashing and burning. It missed the changeover from 2G to 3G and they were suffering because of that judgement call.

Legere set the company on an immediate upgrade. They skipped over the 3G hurdle and went right to 4G. He created the image of a smaller competitor getting back on track. It took years for the company to improve its network to the current level. But they have done a good job and had success over the last several years.

Sprint has lots of wireless data spectrum

Sprint was also struggling. Masayoshi Son, CEO of Softbank acquired the majority of Sprint. He is very successful in Japan and wants to expand his reach to the USA. His intention after acquiring Sprint was to also acquire T-Mobile, but US regulators made it clear that would not happen at that time.

Next, Masayoshi Son hired Marcelo Claure to be CEO of Sprint and the company spent the last several years trying to compete in the US. They have had a few high points which led us to think they were turning the ship around, but they simply could not catch the long-term growth wave they were chasing.

However, Sprint does own lots of wireless data spectrum, which is like gold in the wireless industry.

Bottom line, T-Mobile is a great marketer, but has very little spectrum. Sprint is not a great marketer but has loads of spectrum.

That’s why these two companies think merging makes sense. They would roll marketing and spectrum together and create an effective third place competitor.

T-Mobile, Sprint merger would combine marketing and spectrum

That makes sense. So, why should regulators let them merge?

Simple. If they don’t merge, as the industry moves ahead into the new 5G future, the industry would have four competitors. Two strong and two weak. AT&T and Verizon compared to T-Mobile and Sprint.

If they do merge, the industry will have three competitors, but they would all be strong. I know regulators would prefer to have four competitors. That made sense five or ten years ago when the wireless industry was a different place.

5G is main reason T-Mobile, Sprint merger makes sense

Today the move to 5G is expensive and unstoppable. We need as many viable competitors as we can get going forward. As much as both T-Mobile and Sprint have improved over the last several years, they are not in a strong position for the transformation to the coming 5G world.

What about all the bluster over the last five years coming from T-Mobile about how they were a rapidly growing giant who is taking no prisoners? Well, that’s just marketing talk. The truth is, they have been growing and are much stronger today than ever before, but they are not ready for the move to 5G on their own.

If we were not moving from 4G to 5G, the need to merge would not be as great. However, it’s that move to 5G that is the whole point. Neither T-Mobile or Sprint have the size or scope to remain a competitive force going forward if they do not come together.

Coming together will mean there will be three strong competitors in the wireless industry. Three strong companies are better than two strong and two weak competitors. That makes the most sense for the industry.

Wireless changing with Project Fi, Xfinity Mobile, Spectrum Mobile, Altice Mobile

Today, there are also more competitors, and even more are joining. Google Project Fi and Comcast Xfinity Mobile are already in the marketplace. Next will be Charter Spectrum Mobile and next year Altice Mobile. Plus, I expect even more companies will enter this space.

So, the wireless industry is strong and getting stronger all the time. And we want to continue to have all the competitors actively battling in the marketplace. Throwing a wrench into the mix is not in anyone’s best interest.

Deciding whether to approve a merger or not is a complex decision. I would say, based on what I hear so far, it makes sense that these two companies get together. If there are any competitive concerns, they can be addressed during the process.

Wireless is the center of the universe moving forward. We want to continue to let the industry grow and transform as it always has done. In the case of T-Mobile and Sprint, the move to 5G is the main reason to let these two companies merge. It will be better for them and it will be better for the marketplace to have three strong competitors rather than two strong and two weak ones.

Data Sheet—T-Mobile CEO John Legere Emerges From Capitol Hill Grilling Unscathed

By Aaron Pressman and Adam Lashinsky, Fortune, June 29, 2018

Maybe you weren’t impressed with the dozens of members of Congress who tried to pin down Facebook CEO Mark Zuckerberg back in April. Lawmakers each had only a few minutes to ask questions and some seemed wildly ill-informed, at best, about how Facebook operated.

Many fewer viewers, no doubt, tuned in to C-Span on Thursday to watch the Senate Judiciary Committee’s subcommittee on antitrust grill T-Mobile CEO John Legere about his proposed merger with rival Sprint (you can catch the replay here). They would have been considerably more impressed. Just three lawmakers—Sen. Mike Lee, Sen. Amy Klobuchar, and Sen. Richard Blumenthal—spent more than two hours quizzing Legere and other witnesses and going through the deal’s promised benefits with a fine tooth comb.

Legere, appearing in a black T-Mobile-logoed sports coat and a magenta T-Mobile tee shirt, was unflappable. “T-Mobile is a proud disruptor,” he declared at the outset, setting a tone that would continue for the entire session. “It is in our DNA. It is what drives my magenta-wearing employees. It is our brand.”

And if a boxing referee adjudicated the hearing, they might say no one laid a glove on Legere. But the senators certainly tried. All three lawmakers brought up apt historical comparisons and asked Legere and his partner in the deal, Sprint executive chairman Marcelo Claure, to account for past contradictory statements. Noting that Legere was now counting cable companies like Comcast as key competitors in the market, Sen. Lee noted “you appear to have walked back some statements you made as recently as February.” Legere, who back then said the cable companies would “fail horribly, miserably, so bad,” danced around the issue. “I’m glad you brought this up,” he began, going on to explain that he meant the cable companies hadn’t been competing up to their potential, but now had over half a million customers and “analysts” said they’d grab 5 million within two years. “They’re becoming a viable player.”

Finding the weakest part of T-Mobile’s case was left to witness and longtime antitrust veteran Gene Kimmelman (whose impressive list of former jobs includes chief counsel to the very subcommittee where he was testifying and chief counsel at the Justice Department’s antitrust division). In short, the carriers claimed they had to merge because competition was failing in the wireless market, with T-Mobile and Sprint unable to do much damage to market titans AT&T and Verizon. But at the same time, Kimmelman said, the carriers also argued that if they merged there would be robust competition from many new entrants like Comcast and Google. “I kind of don’t think you can have it both ways,” he observed deep into the hearing. “There’s a problem here in the whole presentation of what’s going on.”

A few other economic experts testified, too, but didn’t add much. As a side note, I still don’t understand how American Enterprise Institute visiting scholar Roslyn Layton, while under oath, offered this whopper: “T-Mobile’s Binge On was wildly popular earning it million of customers. What was the response of the prior FCC and now the California legislature? Shut down the program consumers love.” The prior FCC under Obama-appointed chair Tom Wheeler reviewed and approved of Binge On. And the California legislature added an exception for such programs last week to a bill it is still considering.

At the end of the day, marathon racer Legere successfully ran through the gauntlet of objections and emerged unscathed. The question now is whether regulators at the Justice Department will agree.
