Sirius Real Estate is in advanced talks to raise an additional €26m (£20.8m) debt capacity from its largest debt facility, which the company would use for acquisitions.
The German business park operator is negotiating a change in its BerlinHyp/PBB facility to create a new €137m (£109.7m) facility with the existing syndicate at an improved interest rate and extended term.
The London-listed company announced the talks in a trading update for the 12 months to 31 March 2016.
During that time, the company has seen its annual rental income exceed €60m (£48m) for the first time.
It said its financial results for the 12 months to 31 March 2016 were expected to be in line with market expectations, with rental growth forecast for the next year as it continued its capital investment programme.
Around 65% of the programme, which aims to transform approximately 1.1m sq ft of unlettable or under-rented space has been completed.
Recent acquisitions have included business parks in Aachen, CöllnParc, Cologne and Mainz.
The acquisition of a further two business parks in Krefeld and Markgröningen are expected to add a further €2.5m (£2m) to its annual rental income when they complete in May 2015.
