What Happened?
American Tower (AMT) stock has spent the better part of the past year trading near multi-year lows despite the company delivering 8% adjusted AFFO per share growth in 2025 and posting a fourth quarter where revenue came in at $2.74 billion, beating the analyst consensus estimate of $2.69 billion.
The overhang is DISH: in January 2026, the satellite-turned-wireless carrier defaulted on its payment obligations under a Strategic Collocation Agreement with American Tower, representing roughly 4% of U.S. and Canada property revenue, or approximately $200 million annually through 2035.
Management moved quickly, removing 100% of DISH revenue from the 2026 outlook on day one and filing a lawsuit to recover the full value of the remaining contract, leaving any future collections as pure upside to the guidance already on the table.
The stock’s dislocation is the gap between what the market is pricing and what the underlying business is actually delivering, as CoreSite, American Tower’s data center platform serving enterprises, cloud providers, and AI workloads across interconnection-rich campuses in major U.S. metros, posted approximately 14% revenue growth in 2025 and is guiding to around 13% growth again in 2026.
CEO Steven Vondran stated on the Q4 2025 earnings call that “leasing demand across our global tower portfolio and data center business remains robust, underpinned by sustained growth in mobile data consumption, continued 5G deployment, and increasing hybrid-cloud and AI-related workloads,” tying each revenue driver directly to structural, multi-year demand trends.
Beyond DISH, the forward runway includes 800 megahertz of higher-frequency spectrum already earmarked for 6G deployment, new build acceleration in Europe with over 700 new sites planned in 2026, and a cost savings initiative targeting 200 to 300 basis points of tower cash EBITDA margin expansion through 2030.
CoreSite achieved Google Gold Verified Peering Provider status in March 2026, establishing dedicated private network interfaces across Atlanta, Denver, Los Angeles, Silicon Valley, and Chicago, adding interconnection density that directly supports AI inferencing workloads management described as its fastest-growing new use case.
Wall Street’s Take on AMT Stock
The DISH default created a clean before-and-after: American Tower stock was a slow-and-steady AFFO compounder before the default and is the same business after it, only now with DISH fully removed from the model and a legal claim worth several billion dollars sitting entirely outside guidance as optionality.
AMT’s free cash flow tells the story the AFFO headline obscures: FCF came in at $3.78 billion in 2025 and consensus now projects 7.4% growth to around $4.1 billion in 2026 before accelerating to around 14% growth in 2027, a trajectory powered by CoreSite’s AI-driven lease-up, 5G densification activity across the U.S. and European tower portfolio, and the cost savings program that has already delivered over 300 basis points of cash EBITDA margin expansion since 2022.
Wall Street has re-rated AMT sharply bullish since the DISH derisking: 13 buys, 5 outperforms, 7 holds, and no sells across 25 analysts, with a mean target of around $215 implying 18% upside and a high target of $260 implying 43% from current levels.
The spread between $260 and $195 captures a genuine debate: bulls see a trough multiple with DISH noise fading and CoreSite’s AI demand accelerating, while the low target prices in continued multiple compression if interest rates stay elevated and AFFO growth remains stuck near 1% for another year.
Priced at roughly 16.7x forward AFFO against a 5-year historical range of 20 to 25x and at 0.79x net asset value per share against a historical premium-to-NAV posture, American Tower stock appears undervalued as the DISH overhang clears and FCF growth reaccelerates toward double digits in 2027.
The signal that reframes the discount: management guided to approximately 5% cash AFFO growth excluding the one-time DISH churn impact, meaning the underlying business is performing precisely in line with the long-term algorithm management outlined — DISH is noise, not damage.
If the AT&T Mexico arbitration resolves unfavorably, it creates a second organic growth headwind on top of DISH churn and adds timing uncertainty to the 2027 reacceleration thesis.
Q1 2026 results on April 28 are the first read on whether CoreSite’s AI pipeline is converting into signed leases and whether U.S. carrier colocation and amendment activity is tracking at the guided 2.5% contribution — the two numbers that directly underpin the 2027 FCF acceleration.
What Does the Valuation Model Say?
The TIKR mid-case model builds to a $319 target using a 5% revenue CAGR and an around 38% net income margin assumption through 2030, implying a 75% total return and a ~13% annualized IRR from the current price, returns anchored by a business that has expanded cash EBITDA margins over 300 basis points in the past three years while navigating the India exit, India sale proceeds redeployment, and now the DISH default simultaneously.
With FCF reaccelerating toward 14% growth in 2027, CoreSite posting its fourth consecutive year of record sales, and the tower portfolio trading at a 21% discount to NAV at a time when management is buying back stock at these levels, American Tower stock is undervalued and the trough multiple reflects a temporary overhang, not a structural deterioration.
The entire investment case hinges on one question: is the 1% guided AFFO growth in 2026 a floor before a multi-year reacceleration, or is it the beginning of a structural deceleration driven by rising interest costs, carrier consolidation, and spectrum alternatives?
The Bull Case
- Excluding DISH churn, 2026 cash AFFO growth tracks approximately 5%, confirming the core business is performing in line with the mid-single-digit long-term growth algorithm
- CoreSite is guiding around 13% data center revenue growth in 2026 and management described AI inferencing demand as exceeding available supply capacity, with over $700 million in success-based data center CapEx planned to replenish sold-out capacity
- The tower portfolio targets 200 to 300 basis points of additional cash EBITDA margin expansion through 2030, driven by four identified cost savings initiatives including global land expense optimization and unified supply chain sourcing
- Any future DISH collections from the ongoing litigation represent pure upside to reported results, with the contract running through 2035-2036 and management estimating the total obligation at approximately $200 million annually
The Bear Case
- Interest expense is rising as debt is refinanced at higher rates, creating a persistent below-the-line headwind that limits AFFO per share growth even when EBITDA is expanding at a healthy pace
- LatAm organic tenant billings growth is guided negative 3% in 2026 as Brazil consolidation churn accelerates, pushing the expected organic growth recovery out to 2027 and adding execution risk to the reacceleration timeline
- The AT&T Mexico arbitration outcome remains unresolved and could create a second named revenue headwind on top of DISH, compounding the organic growth drag in the international portfolio
- CoreSite data center margins face a 270 basis point step-down in 2026 as one-time 2025 property tax benefits do not repeat, masking the underlying growth and creating near-term margin optics that could weigh on sentiment
