American Tower is trading 6.5% up at $177.57 after reporting strong Q2 results and raising its full-year 2026 guidance, driven by robust data center performance. - The company's Q2 revenue of $2.75 billion surpassed analyst expectations, and it increased its outlook for property revenue, Adjusted EBITDA, and AFFO per share for the full year 2026. - This positive performance was fueled by strong leasing demand across its global tower portfolio and record leasing activity at its CoreSite data centers. - The stock's upward move is being reinforced by a broader rally across real estate REITs following the positive earnings report.
