ts of climate change and extreme weather conditions; and •Our ability to increase the property’s long-term financial returns. Development, redevelopment, and pre-construction A key component of our business model is our disciplined allocation of capital to the development and redevelopment of new Class A/A+ properties, as well as property enhancements identified during the underwriting of certain acquired properties. These efforts are primarily concentrated in collaborative Megacampus ecosystems within AAA life science innovation clusters, as well as other strategic locations that support innovation and growth. These projects are generally focused on providing high-quality, generic, and reusable spaces that meet the real estate requirements of a wide range of tenants.
Upon completion, each development or redevelopment project is expected to generate increases in rental income, net operating income, and cash flows. Our development and redevelopment projects are generally in locations that are highly desirable to high-quality entities, which we believe results in higher occupancy levels, longer lease terms, higher rental income, higher returns, and greater long-term asset value. Development projects generally consist of the ground-up development of generic and reusable laboratory facilities. Redevelopment projects consist of the permanent change in use of acquired office, warehouse, or shell space into laboratory space. We generally will not commence new development projects for aboveground construction of new Class A/A+ laboratory space without first securing significant pre-leasing for such space, except when there is solid market demand for high-qual

Behind the comparison

Sources and methodology

Price return uses split-adjusted daily closes and excludes dividends. Both stocks start on the first shared trading day within the selected window. Unavailable metrics leave gaps.

Financials use SEC canonical statements available by the displayed cutoff, retaining each company's fiscal period end. Annual and quarterly amounts are shown separately. P/E is unavailable when earnings do not support a positive ratio.

Business overlap uses industry tags from annual filings released in 2025. Each core activity receives full weight; each material activity receives one quarter of that weight. Rarer industries carry more weight. We sum the smaller exposure for each shared activity and divide it by the sum of the larger exposure for every activity in either company. This measures business overlap, rather than price correlation or expected returns.

Search eligibility requires distinct issuers, a shared core category and at least 20% weighted overlap, supported by industry or sector evidence and specific business activities. Broad classifications require stronger overlap within the same sector. Comparisons also need at least 252 shared price observations within two years, recent trading and a common sourced revenue or net-income trend. Missing P/E or gross margin alone does not exclude a comparison. The eligibility snapshot refreshes daily. Related comparisons use a separate, stricter peer rule; their ten-peer discovery limit does not limit search eligibility. Other stock pairs remain available in the comparison tool.
