With our founding in 1994, Alexandria pioneered the life science real estate niche. Alexandria is the preeminent and longest-tenured owner, operator, and developer of collaborative Megacampus ecosystems in AAA life science innovation cluster locations, including Greater Boston, the San Francisco Bay Area, San Diego, Seattle, Maryland, Research Triangle, and New York City. As of September 30, 2025, Alexandria has a total market capitalization of $27.8 billion and an asset base in North America that includes 39.1 million RSF of operating properties and 4.2 million RSF of Class A/A+ properties undergoing construction and one 100% pre-leased committed near-term project expected to commence construction in the next year. Alexandria has a long-standing and proven track record of developing Class A/A+ properties clustered in highly dynamic and collaborative Megacampus environments that enhance our tenants' ability to successfully recruit and retain world-class talent and inspire productivity, efficiency, creativity, and success. Alexandria also provides strategic capital to transformative life science companies through our venture capital platform. We believe our unique business model and diligent underwriting ensure a high-quality and diverse tenant base that results in higher occupancy levels, longer lease terms, higher rental income, higher returns, and greater long-term asset value.

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.
