AMT Options Turn Bullish Ahead of Q3 Earnings

American Tower reports Q3 results today with its shares at $188.28, up nearly 3% over the past week and more than 11% over the past month, extending a recovery that followed a 7.5% one-day jump after the last quarterly print in July.

The most distinctive signal heading into this release is the shift in options positioning. The put/call ratio has dropped to 0.59, more than 1.7 standard deviations below its 20-day average of 0.73, placing it near the lowest reading of the past year. That reflects an unusual tilt toward calls rather than protective puts, the opposite of what most stocks show ahead of an uncertain print. The borrow market reinforces the picture: short interest is just 1.5% of the free float, availability is effectively unlimited with hundreds of millions of shares available to lend, and the ORTEX short score of 30 has barely moved in two weeks. There is no meaningful short-side conviction here.

The analyst community is broadly constructive, though not without caveats. The consensus price target of $215.74 implies roughly 15% upside from current levels, and recent moves have been minor adjustments rather than directional changes. Bernstein trimmed its target by $2 to $212 last week while keeping an Outperform rating, and Barclays lifted its target modestly to $199 in September after upgrading the stock in August. Director Rajesh Kalathur bought 2,829 shares at $177 in August, a purchase worth roughly $500,000 and the most substantive open-market insider buy in recent months. Net insider activity over the past 90 days is a modest net negative in dollar terms, but that largely reflects smaller plan-linked sales rather than any signal of management caution.

The fundamental debate divides on organic growth. Bears point to tenant billings growth slowing sharply to 1.7% from 5.9%, with the U.S. and Canada segment barely positive at 0.6% and Latin America contracting. DISH churn continues to drag, and management has already described 2026 as a period of suppressed carrier activity. Bulls counter with the CoreSite data center business, which is growing around 18% on AI and cloud demand, a leverage ratio now below 5x, and an expectation that AFFO-per-share growth accelerates from roughly 3% this year toward 7% by 2028 as churn rolls off and European tower builds pick up. Peer Crown Castle gained 7.9% on the week and SBA Communications added 1.5%, meaning AMT's 2.9% weekly gain was actually behind its closest comparable.

The Q3 print will test whether the recovery in organic growth that the bull case requires is starting to show up in the numbers, or whether the slowdown in carrier spending has further to run before any acceleration becomes visible.
