American Tower Corporation: Tower Profile

    American Tower Corporation is one of the large US and international tower companies. As of year-end 2023, they own 42,857 towers in the US along with another 800 “properties” which primarily consist of distributed antenna systems and rooftop sites. American Tower Corporation generates revenue by collocating space on its towers to wireless carriers. Overall, 44% of its revenue comes from international carriers and 56% 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. To do so, they must contact landowners to enter into what the industry refers to as a ground lease or in the case of acquired towers, assign the lease from the old company to the new company.


    Here are some interesting statistics about American Tower US tower portfolio.
    1. From 2020-2022, American Tower built less than 50 new towers in the United States.
    2. During that same time, they decommissioned 180 towers.
    3. American Tower has done lease buyouts on the ground leases under 13,000 of its towers.  (33% of all towers in the US).
    4. 90% of American Tower tower site ground leases are held by landlords who own a single site.
    5. American Tower has an average term remaining of 30 years on its ground leases.


    As of the end of 3Q 2023, American Tower had an average of 30 years remaining on average for all its cell tower ground leases in the US which represents a 6-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 a party to leases with over 35,000 individual property owners.

    From 2020-2023, American Tower has paid over $628,000,000 to property owners to purchase their leases. Typically, American Tower does this by purchasing a long-term easement under the lease from the landowner. (see quick fact #3 above)


    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 three 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
    3. In the case of a lease buyout, to change the ongoing operating expenditure (Opex) for the lease and convert it to capital expenditure (Capex). This is particularly important for Real Estate Investment Trusts.
    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 20 years, Steel in the Air has assisted over 700 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 Offers: 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 its 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.

    Please contact us to discuss any questions you might have about a proposal you have received from American Tower Corporation. The initial discussion is free and once we talk to you and understand your needs, we can advise you as to what the costs would be should you choose to retain our services. Unlike our competitors, we offer the flexibility of either a fixed-fee consulting service or a contingency-based service.


    Wireless carriers and tower companies often send notices to their Lessors (e.g. landowners, building owners and structure owners) stating that the Lessor must consent to certain equipment modifications. This is not necessarily true. In many cases, you can negotiate better terms (or receive some form of compensation) in exchange for your “consent.”
    The trend with new cell site leases is to include a “Right of First Refusal” clause. This means that if a third-party were interested in buying your lease you would first have to offer it to the original Lessee. This could substantially lower the final purchase amount. While it might not be possible to avoid the ROFR clause altogether, you might be able to negotiate away from “pro-rata” matching.
    We advise our clients to remove the blanket “Right to Sublease” clause from rooftop cell site leases. Contact us for more details.
