Well, the numbers rarely tell the whole story. Luckily, public companies tend to let senior management discuss each quarter, in much greater detail, in a conference call with analysts. Of course, American Tower followed that great tradition in the second quarter.
Here are five of the most important, interesting, or incredible details shared by American Tower on that call. CEO Jim Taiclet has made a tradition out of addressing international issues in the second-quarter call every year, so expect to go on a safari overseas.
The big international picture
"This has been a long journey," Taiclet said. "Over the last 15 years, we've carefully selected a series of markets, interconnected through a strong core of common multinational customers, solid underpinning of rule of law and property rights, and long-term wireless industry growth potential.
"For markets where 4G is being deployed, like the U.S. and Germany, to markets where additional voice networks are still being built out, such as India, we're positioned to benefit from carrier investments in both the short and the long term."
In other words, American Tower has a two-pronged approach to overseas markets.
On one hand, the company invests in highly developed and stable markets, including more than 2,000 tower sites in Germany and 8,700 towers in Mexico. Alongside the 40,000 domestic sites, these properties form a solid cash-generation foundation from which the company can launch further high-growth projects.
And that's the other prong: big investments in underdeveloped markets with huge growth potential. American Tower operates more than 3,600 towers in Colombia, nearly 14,000 sites in India, and recently added 4,200 Brazilian towers for a grand total of 16,300 sites inside that BRIC bloc member.
This is where the company is looking for strongly growing returns on the original investment, rather than the stable cash flows you'd expect in developed markets. American Tower is getting in on the ground floor where much of the wireless network builds still lie in the future. It's a calculated risk, which is why Taiclet insists on "rule of law and property rights" before moving in.
"If you want to take a snapshot of Brazil," Taiclet said, "the four carriers there are trying to, on one hand, manage all the mobile data demand that's coming down the road with cheaper smartphones and more penetration, and getting ready for the Olympics, which is in 2016. So, all of the drivers in our business tend to not be for one half or one quarter to come and go, but they tend to be over many years.
"As smartphone prices continue to drop, penetrations [climb] and, today, it stands over 35% as compared to under 10% of smartphone penetration just five years ago in Brazil. Furthermore, industry projections call for mobile data usage to grow approximately eightfold in Brazil over the next five years, prompting the leading mobile operators in that country to recommit significant network investment.
"With over 4,000 SIM cards per cell site, or about double that of the United States, Brazilian networks are extremely congested and increasing mobile data usage is compounding the issue.
"I think, with the new Finance Minister in place and government policies that he and President Rousseff are implementing, you're going to see a comeback by Brazil over the next few years on a larger scale. We think it's very supportive.
"And, the last point I'll make about Brazil is, who are these mobile operators? They are global, multi-national, very well-capitalized companies with long-term views of their business. And they're stepping up their investment in this market, even while it may be sort of a down-tick year on some of the in-country metrics."
That's a pretty deep dive into American Tower's largest overseas market. The growth drivers here are laid out in great detail, from the booming middle class and falling smartphone prices to currently congested networks and the upcoming Olympics.
In short, Brazil is already a large wireless market -- but the country still has lots and lots of headroom for even further growth.
"In Nigeria, we're already seeing indications of very strong demand as we convert formerly captive, underutilized Airtel assets into the multi-tenant commercial real estate leasing model," said Taiclet.
"With the largest population in Africa, very limited fixed-line infrastructure, a competitive wireless sector, and a massive need for better networks, we believe we can aggressively add tenants to our portfolio of approximately 4,700 sites there.
"Given our acquired return hurdles in Nigeria, even with one tenant, these assets have an net operating income yield of over 8% and by adding just one more tenant, we believe we can grow those yields to 17% or more. This illustrates the huge potential we see in this market."
Jumping across the Atlantic, Nigeria is a brand new addition to American Towers' portfolio. In a $1.05 billion deal with India-based telecom titan Bharti Airtel, American Tower acquired 4,700 Nigerian Airtel towers in November 2014.
Here, Bharti has aggressively kept its tower sites close to the vest, largely refusing to lease the properties out to other operators. Under new management, these towers are not only tied back to Bharti Airtel in a 10-year guaranteed contract but will also invite other telecoms to populate these sites.
As Taiclet explained, adding more tenants to existing but underutilized sites can grow operating profits very quickly. Given that, Bharti Airtel is only the third-largest wireless network in Nigeria with a modest 20% market share.
Nigeria is the seventh-largest country by population in the world, home to 174 million people. The population skews young, and Nigeria's economy is both large and growing fast. In many ways, this makes Nigeria the Brazil of Africa -- a large, yet still emerging, economy with all kinds of foreign investors wanting to get in.
The biggest question, then, is how much longer this massive market can be served through a relative pittance of wireless towers. Those 4,700 Bharti Airtel sites currently serve 29.6 million customers. That's 6,300 users per Bharti tower. I wouldn't be surprised to see American Tower making more acquisitions in this important market -- or maybe even build out a few properties under its own power.
Customer stories: AT&T
"We have a holistic agreement with AT&T (NYSE: T) that's run a few years now, designed to give them a steady opportunity to continue to deploy equipment on our sites under that agreement," said Taiclet. "And they are.
"The other benefit of that agreement for us is when they're in a grooming period, as they are now, you'll recall that 18 to 12 months ago AT&T was doing really outsized investment in their network. When you have an outsized investment, you tend to have a little bit longer grooming period to get that investment in the network tuned perfectly, see how it performs, and then you go into another reinvestment cycle.
"We're in the trough of that now, but our holistic agreement keeps their revenues with us pretty steady."
OK, now we're back home.
Right now, Ma Bell sits in-between the last major network build and the next wholesale refresh. Look for renewed investment activity after the FCC's 2016 auction of formerly TV-focused radio spectrum licenses. All the major networks are likely to bid on these high-quality licenses. Then we'll see both reinforced 4G networks and the beginnings of a 5G transformation, all of which requires fresh tower space.
Did I tell you about additional tenants per tower driving revenue and profit margins higher very quickly? Yeah, I did. Don't forget that bit.
With that event on the horizon, I'm happy to be an American Towers shareholder. The last major FCC spectrum action was held in 2008, just ahead of the smartphone boom.
Coincidence or one revolution feeding off another? You be the judge. Here's how American Tower fared when those licenses were converted into wireless operations:
"I'd say our leasing trends are well established and in place," Taiclet said. "It's the four carriers I talked about in the U.S.
"Verizon (NYSE: VZ), very stable, long-term network plans, steady investment. They have spectrum that they're deploying in a deliberate fashion over a long period of time in a couple different bands.
"T-Mobile (NYSE: TMUS), very successful on the net add side, therefore justifying roaming, overbuilds, et cetera. All of those things are not quarter-to-quarter for any of these customers, frankly. They're very long term."
This is Taiclet talking about his favorite customers of the moment. Elsewhere in the call, Taiclet noted that Verizon and T-Mobile "led the way in terms of both new leases and amendments in Q2, and continued to comprise the bulk of our new business pipeline."
But none of that is exactly news. Like American Tower, the telecoms must operate with tons of patience. Network builds are slow and expensive, and then you have the regular maintenance. That's why the wireless tower business is so fantastically stable. In the second quarter, for example, American Tower renewed the lease terms on about 500 domestic towers. The average contract period on these renewals? Twenty-nine years.
So, once you have a customer in hand, that cash flow will remain stable for decades. The way to grow in this business is by expansion, acquisition, and adding more tenants per tower. And American Tower is aggressively pursuing all three of these growth strategies.
