NEW YORK—LinkedIn Corporation has expanded its lease at the Empire State Building and will occupy more than 72,000 sq. ft. on two full floors of the W&H Properties-owned property. Malkin Holdings supervises the property.

Sacha Zarba of CBRE represented LinkedIn in the lease negotiations, while William Cohen and Ryan Kass of Newmark Grubb Knight Frank represented the landlord. Attorneys involved in the transaction were Deborah Churton Aikins of Liuzzi, Murphy, Solomon & Aikins LLP for the tenant and David Bleckner and Ian Lester of David Bleckner PC for the landlord.

In 2011, LinkedIn originally leased 32,000 sq. ft. at the building, occupying the entire 25th floor. The new lease includes the entire 23rd floor, which contains approximately 40,000 sq. ft. The company will move into its new space next year.
