• The ongoing shift towards the decentralization of healthcare delivery, with an increasing prevalence of outpatient facilities, urgent care centers, and retail health clinics. This trend could diminish the demand for traditional, larger medical office buildings that constitute a significant portion of DHC's portfolio, as care moves closer to where people live and shop, potentially impacting occupancy rates and rent growth.
• The sustained and growing adoption of telehealth services post-pandemic. If a significant portion of routine medical consultations permanently shifts to virtual platforms, it could reduce the overall physical space required by healthcare providers for exam rooms and waiting areas, thereby decreasing future demand for traditional medical office space and potentially impacting DHC's leasing activity and rental income.
• Chronic and worsening labor shortages across the senior living and healthcare sectors. These shortages directly impact the operational viability and profitability of DHC's senior living operators (tenants), limiting their ability to admit residents, maintain occupancy, and generate sufficient revenue. This, in turn, poses a direct threat to DHC's ability to collect rent and maintain stable income from its senior living portfolio.

Diversified Healthcare Trust (DHC) operates as a real estate investment trust (REIT) primarily focused on owning and leasing healthcare properties across the United States. Their main products and services include senior living communities, medical office buildings, and life science properties.

Addressable Markets for Diversified Healthcare Trust's Main Products or Services (U.S. Region):

• Senior Living Communities: The addressable market for senior living in the U.S. was estimated at approximately $907.59 billion in 2024 and is projected to reach $943.90 billion in 2025. This market is expected to grow to around $1.39 trillion by 2033.

Diversified Healthcare Trust (DHC) is expected to drive future revenue growth over the next 2-3 years through several key strategies and market trends:

1. Senior Housing Operating Portfolio (SHOP) Occupancy and Rate Improvements: DHC has demonstrated consistent growth in its Senior Housing Operating Portfolio, with occupancy rising by 210 basis points year-over-year to 81.5%, marking four consecutive quarters of occupancy growth. The company anticipates further gains as occupancy trends continue to improve and average monthly rates increase, with year-over-year same-property SHOP revenue growing by 6.6%. This sustained recovery in senior housing demand is a core belief for DHC shareholders.

2. Medical Office and Life Science Leasing Success: DHC has shown strong performance in its medical office and life science segments, completing approximately 86,000 square feet of leasing at weighted average rents 9% above prior rents, with an average lease term of nearly seven years. This success, coupled with an increase in consolidated occupancy in this portfolio by 370 basis points sequentially to 86.6% (driven by strategic asset sales and new leasing), underscores the company's strong position in these high-growth sectors.

3. Portfolio Optimization and Strategic Asset Sales: The company is actively optimizing its portfolio through asset dispositions. DHC has sold 44 properties for $396 million year-to-date and has agreements to sell an additional 38 properties for $237 million. These sales are aimed at enhancing liquidity, reducing capital expenditures, improving overall occupancy and margins, and contributing to cash flow growth. The full transition of 116 AlerisLife-managed communities to new operators, expected to be completed by year-end, is also anticipated to yield $25 million to $40 million in net proceeds in 2026 and contribute to margin expansion through performance-based incentive structures.

4. Leveraging Aging Demographics and Healthcare Tailwinds: An overarching driver for DHC is the favorable demographic trend of an aging population, combined with advancements in medical technologies. DHC has made significant portfolio-wide investments in its medical office, life science, and senior housing assets, positioning the company to capitalize on these powerful tailwinds and serve increasing demand in the healthcare real estate sector.
