Mizuho Upgrades American Tower to Outperform: Will This Cell Tower Giant Finally Reclaim Its Crown?

Analysts at Mizuho just gave a thumbs-up to American Tower (NYSE:AMT | AMT Price Prediction) stock, upgrading the cell tower giant from Neutral to Outperform with a new price target of $205, up from $189. The call comes from Mizuho analyst Vikram Malhotra, who sees a compelling setup after prolonged underperformance.

AMT stock has declined 19% over the past year, while the broader REIT sector is up 10% over the same period. Malhotra’s core argument: several negatives are already priced in, and two catalysts could drive a meaningful multiple re-rating.

The Analyst’s Case

Malhotra sees two drivers. First, he believes U.S. and several non-U.S. cell tower fundamentals are inflecting, signaling leasing demand is picking back up. That view aligns with American Tower’s own reported organic tenant billings growth of 6% in Q4 2025.

Second, Malhotra views American Tower’s data center business as “materially undervalued with several paths to unlocking value.” That business, operated under the CoreSite brand, posted $281 million in revenue during Q4 2025, up 19% year-over-year. With $695 million in data center development spend planned for 2026, the growth runway looks durable.

Company Snapshot

American Tower is a global REIT that owns and operates wireless communications infrastructure, including cell towers and data centers, across multiple continents. The Africa and APAC segment grew 24% in Q4 2025, while Europe expanded 16%, showing international markets are a significant growth engine for the company.

On the balance sheet, American Tower has returned to its target leverage range, with net debt to annualized adjusted EBITDA at 4.9x. The company also repurchased roughly 2 million shares for $365 million in Q4 2025, with $1.6 billion remaining under the buyback program.

Why the Move Matters Now

The rate environment is shifting in ways that benefit REITs. The 10-year Treasury yield has pulled back from a recent peak of 4.44% on March 27 to 4.3% as of April 13, easing pressure on income-generating infrastructure stocks. AMT stock trades near $177, well below its 52-week high of $227.77.

American Tower CEO Steven Vondran struck a confident tone on the Q4 earnings call, noting:

“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.”

The company’s 2026 guidance calls for net income of $2,945 million to $3,025 million, representing roughly 14% midpoint growth. For more context on analyst sentiment shifts across infrastructure and tech names, see this recent look at analyst upgrades and the physical AI buildout thesis.

What It Means for Your Portfolio

For income-focused investors, American Tower offers a dividend yield of around 4%, with the quarterly dividend growing 5% year-over-year to $1.70 per share. The 2026 AFFO per share guidance of $10.78 to $10.95 gives income investors a clear picture of cash generation supporting that payout.

Risks remain, however, including American Tower’s FX headwinds, customer concentration, and modest headline AFFO growth of roughly 1% at the midpoint. AMT stock could be worth a closer look if you believe 5G leasing demand is reaccelerating and the data center business is undervalued. If those catalysts don’t materialize on schedule, the recovery thesis loses its foundation.
