Financial Impact Assessment

Impact Evaluation

• Market Cap Context: As a large-cap company with a market capitalization of $26.29 billion, the reported full-year 2025 revenue of $6.9 billion and Adjusted EBITDA of $2.6 billion represent substantial operational scale. The projected 2026 revenue growth to ~$7.7 billion is a significant top-line expansion.
• Profitability and Shareholder Returns: The company delivered record Adjusted Funds From Operations (AFFO) of $5.17 per share for 2025, a 14% increase YoY. The declaration of a $0.864 per share quarterly dividend reinforces its commitment to returning capital to shareholders, a key metric for REIT investors.
• Growth Drivers: The report emphasizes that growth businesses (Data Center, Digital, ALM) collectively grew over 30% in 2025 and now represent 28% of total revenue. This diversification reduces reliance on the traditional physical records business and positions the company in higher-growth markets.
