Equity Residential Announces Creation of ATM Share Offering Program

Chicago, IL—September 29, 2009—Equity Residential (NYSE: EQR), today announced that the company has created an At-The-Market (ATM) share offering program through which it could sell up to 17 million common shares. The shares would be offered through BofA Merrill Lynch, J.P. Morgan and Morgan Stanley, who will be acting as sales agents.

“With more than $800 million of cash, $1.36 billion of availability under our credit facility and the continued ability to sell non-core assets, we see no immediate need to sell common shares,” said David J. Neithercut, Equity Residential’s President and CEO. “This program will, however, allow us to quickly access the equity market should that capital be necessary to fund future investment opportunities.”

The ATM program would allow the company to sell up to 17 million common shares from time to time through the sales agents for a 36-month period. The sales, if any, would be made in “at the market” offerings as defined in Rule 415 of the Securities Act. In addition, the common shares may be offered and sold through privately negotiated transactions. The company intends to use the proceeds from any offering for working capital and general company purposes including, without limitation, the acquisition or development of multifamily properties as suitable opportunities arise and the reduction of debt.

The company has filed a registration statement (including a prospectus) with the SEC for the offering of common shares described in this communication. Before you invest, you should read the prospectus in that registration statement and other documents the company has filed with the SEC for more complete information about the company and this offering. You may obtain these documents for free by visiting EDGAR on the SEC website at www.sec.gov.
