WASHINGTON — Washington’s newest publicly-traded company rang the opening bell at the New York Stock Exchange Wednesday morning.

CEO Matt Kelly and other senior executives from JBG Smith Properties were at the exchange floor’s podium to mark the company’s official trading on the New York Stock Exchange under the trading symbol “JBGS.”

The stock officially began trading last week.

Chevy Chase, Maryland-based JBG Cos.’ merger with Vornado Realty’s Charles E. Smith commercial real estate business combined the D.C.-area portfolio of Charles E. Smith’s Washington holdings to create a company with 20 million square feet of office, multifamily and retail property space.

JBG Smith Properties also has more than 18 million square feet of potential development in the works.

The combined company has a market capitalization of $4.1 billion.

JBG Smith Properties will move its headquarters from Chevy Chase to Bethesda, to a JBG building under construction at 4747 Bethesda Ave., when construction is complete in late 2019.
