SL Green Realty Corporation is the largest office landlord in New York City. The firm is an S&P 500 company publicly-listed on the New York Stock Exchange.

As a fully-integrated REIT, SL Green focuses on acquiring, managing, and maximizing the value of its holdings – primarily in the Manhattan commercial real estate office market.

The largest owner of commercial real estate in New York City

Founded in 1980 by Stephen L. Green, SL Green Realty has been directly involved in acquiring over 125 properties with over 65 million square feet of rentable space. By strategically acquiring, redeveloping, and repositioning high-quality office property the firm consistently maximizes property cash flow and obtains the highest possible total return to its stockholders.

In 1997 SL Green issued its IPO on the New York Stock Exchange. It was the first public REIT that focused solely on New York City commercial real estate and has experienced enviable growth ever since. When the company went public its property portfolio consisted of just six properties and 1.2 million square feet of space, and a market cap of $210 million.

Today SL Green is an S&P 500 company with an equity market cap of about $11 billion. The company’s property portfolio now contains interests in 125 office and retail buildings and over 65 million square feet of space.
