NEW YORK, July 13, 2012 /PRNewswire/ -- Alexandria Real Estate Equities, Inc. (NYSE: ARE), the largest and leading owner, operator and developer of high-quality, sustainable real estate for the broad and diverse life science industry in key innovation clusters, announced that it will ring The Closing Bell at the NYSE today, Friday, July 13, 2012, to commemorate the Company's 15th anniversary as a publicly traded company.

The board of directors and members of Alexandria's executive management team will join Joel S. Marcus, Chairman, Chief Executive Officer and Founder of Alexandria, as he rings The Closing Bell at 4:00 p.m. EDT. A live webcast of the ceremony will be available beginning at 3:59 p.m. EDT at the NYSE's website, www.nyse.com.

"We are honored that the NYSE has invited us to ring The Closing Bell as we celebrate 15 years as a publicly traded company," said Mr. Marcus. "This milestone achievement and Alexandria's record of long-term success are a result of our world-class employees, investors, life science network and client tenant partners who continue to position Alexandria as the leader in life science real estate."

Alexandria was founded in 1994 by Mr. Marcus and Dr. Jerry Sudarsky as the first real estate investment trust (REIT) to identify and specialize in the life science niche. From its origination as a garage start-up, the Company went public on the NYSE in May 1997. Since that date, the Company has generated a total return of approximately 570% through June 30, 2012, assuming the reinvestment of all dividends. In July 2011, Alexandria received investment-grade ratings, which reflect the Company's continued leadership of the life science real estate niche; the strength of its credit profile and business; the size and quality of its real estate holdings; its consistent operating and leasing performance; its unmatched life science and real estate experience and expertise; the importance of its key cluster locations; stable net operating income from high-credit client tenants; and its continued focus on maintaining a conservative balance sheet. This is also a testament to the Company's high-credit life science industry client tenant base, a defining and unique characteristic of Alexandria. As of June 30, 2012, investment-grade client tenants represented approximately 47% of Alexandria's annualized base rent and included Novartis AG, Eli Lilly and Company, Roche Holding Ltd, Pfizer Inc., Biogen Idec Inc., The Regents of the University of California, and Bristol-Myers Squibb Company.
