BERLIN (Reuters) - Adler Group on Thursday entered a non-binding agreement with bondholders to restructure its debt as the embattled German landlord struggles to sell property to cover its liquidity needs amid a real estate market slowdown.

Adler, one of Germany's biggest landlords, is fighting a liquidity crisis triggered by a downturn in the domestic property market, rising energy and building prices caused by Russia's invasion of Ukraine and the fallout from the COVID-19 pandemic.

Although it managed to divest real estate assets worth 530 million euros ($568.32 million) last year, the amount of deals lags the original plans, Adler's statement said.

Therefore, the firm agreed with bondholders to postpone repayment of part of its debt beyond 2026-2027.

"The perfect storm in the financing and transaction parts of our industry is not yet over, but market turbulence has calmed down," Chief Executive Thierry Beaudemoulin said.

The restructuring programme and portfolio devaluations weighed on its finances, with the bottom-line loss deepening to 1.8 billion euros in 2023, down almost 200 million euros from a year ago.
