As used in this quarterly report on Form 10-Q, references to the “Company,” “Alexandria,” “we,” “our,” and “us” refer to Alexandria Real Estate Equities, Inc. and its subsidiaries.

Alexandria Real Estate Equities, Inc. (NYSE: ARE), a self-administered and self-managed real estate investment trust (“REIT”), is the largest and leading investment-grade REIT focused principally on owning, operating, redeveloping, developing, and acquiring high-quality, sustainable real estate for the broad and diverse life science industry.  Founded in 1994, Alexandria was the first REIT to identify and pursue the laboratory niche and has since had the first-mover advantage in every core life science cluster location including Greater Boston, San Francisco Bay, San Diego, New York City, Seattle, Suburban Washington, D.C., and Research Triangle Park. Alexandria’s high-credit client tenants span the life science industry, including renowned academic and medical institutions, multinational pharmaceutical companies, public and private biotechnology entities, United States government research agencies, medical device companies, clean technology companies, venture capital firms, and life science product and service companies. As the recognized real estate partner of the life science industry, Alexandria has a superior track record in driving client tenant productivity and innovation through its best-in-class laboratory and office space, collaborative locations adjacent to leading academic and medical institutions, unparalleled life science real estate expertise and services, and longstanding and expansive network in the life science community, which we believe result in higher occupancy levels, longer lease terms, higher rental income, higher returns, and greater long-term asset value.
