alstria leases 7,600 sqm in "Am Seestern 1" (Düsseldorf)

Hamburg, May 29, 2017 - alstria office REIT-AG (symbol:PMOX, ISIN: DE000PRME020), announces the signature of a new lease for its asset "Am Seestern 1" in Düsseldorf.

The new tenant, a leading information technology company, will lease up approximately 7,600 sqm of office and ancillary space on a long-term lease basis. The lease is scheduled to start as per December 1, 2017 and will generate an annual rental income of around EUR 1.3 million. The 36,200 sqm building "Am Seestern 1" in Düsseldorf is the last building with substantial vacancy out of the portfolio alstria acquired with the takeover of former Deutsche Office in 2015.

"With the implementation of our successful lease-up strategy we continue to extract the value of the assets we acquired in the Deutsche Office transaction", says Olivier Elamine, CEO of alstria office REIT-AG. "Following the success in Frankfurt on the Kastor asset which is now around 85% let, this new leasing in the "Seestern 1" in Düsseldorf again demonstrates the ability of alstria to add value through the active management and repositioning of office assets. The German leasing market remains extremely supportive and we look forward to continue taking advantage of it."

The tenant was advised by Colliers, JLL was lead broker in the letting process.
