American Tower Corporation is one of the large US and international tower companies. Currently (Q3, 2018), they own 40,247 towers in the US along with another 800 “properties” which primarily consist of in-building DAS agreements and some limited ODAS (outside DAS) rights. In addition to individual landowners, building owners and local governments, American Tower Corporation generates revenue by collocating space on their towers to wireless carriers. Overall, 46% of its revenue comes from international carriers and 54% from the US. In the US, this revenue is generated primarily from the big 4 wireless carriers.

American Tower Corp acquired most of their tower portfolio through larger historical acquisitions of Global Tower Partners, Spectrasite, Airtouch (Verizon), Alltel (Verizon), Cingular (AT&T), and Nextel (Sprint). It also builds new towers, leasing land from landowners. From Q3 2017 to Q3 21018, ATC added approximately 250 towers in the United States although the number is likely higher due to lease terminations during the same time. To do so, they it must contact landowners to enter into what the industry refers to as a ground lease.

As of the end of Q3 2018, American Tower had an average of 28 years remaining on average for all its cell tower ground leases in the US which represents a 4-year increase from the same time in 2014. (In other words, American Tower continues to buy or extend its leases.) Of the towers ATC owns in the U.S., approximately 90% of them are on property where the property owner only has one tower lease altogether with American Tower. This means that ATC is party to leases with over 35,000 individual property owners.

Over the last year, American Tower has paid over $154,000,000 to property owners to purchase their leases. This means that American Tower has acquired over 5,000 ground leases from landowners. Typically, American Tower does this by purchasing a long-term easement under the lease from the landowner


Why would American Tower purchase an easement?


This is because the revenue that American Tower generates is tied to its ability to keep the tower on the property. Since the typical lease provides that the lease can be terminated only by ATC, this amounts to a one-way commitment on behalf of the landowner.

There are two primary motivators for American Tower to extend or purchase existing ground leases:

  1. To get to landowners prior to the landowner retaining an expert who can help them understand the true value proposition in the lease; and
  2. To prevent the landowner from selling the lease to a third party lease buyout company

Because of substantial, competing interests in ground leases by third-party buyout companies (especially those under tower company towers), ATC has been proactive (and some might say aggressive) in its efforts to acquire or extend its existing ground leases. This often leads the landowner to perceive that they must do something with their lease immediately, even when that’s not the case.

Over the last 10 years, Steel in the Air has assisted over 600 landowners who have been contacted by American Tower Corporation regarding lease proposals, extensions and buyouts. We have reviewed thousands of proposals from ATC. As part of our day to day operations, we track these proposals so that our clients have the benefit of knowing what American Tower offers initially and what they will ultimately agree to. We can bring this experience to bear on your situation, and provide actual knowledge of how ATC negotiates and either negotiate or assist you in negotiating your lease with American Tower Corporation.




There are five proposals that landowners receive from American Tower:

  1. American Tower Lease Buyout: AMT offers to purchase the ground rights under their existing tower through a perpetual or fixed term easement.
  2. American Tower Ground Lease Extension: AMT proposes to extend their ground lease for 30-50 years. They typically offer a nominal signing bonus and will sometimes offer to increase the rent going forward.
  3. American Tower Proposed Cell Tower Lease: AMT contacts a landowner to enter into a lease to erect a tower on the property.
  4. American Tower Rooftop Lease Purchase Offer: AMT has recently formed a Rooftop Lease Buyout division to contact building owners who have rooftops where they lease space to wireless carriers directly. They then propose to acquire the rooftop leases plus the rights to the remaining space on the rooftop so that they can lease to other wireless carriers.
  5. American Tower Lease Expansion or Consent Requests: AMT will contact their existing landowners to request the right to expand their lease footprint or to receive consent to sublease space on the tower to a wireless provider.
