German real-estate giant Vonovia SE acquired a purchase option for a 13.3% stake in Adler Group SA, Adler shareholder Aggregate Holdings SA said on Thursday.

The price is significantly more than Adler's latest closing share price and the call option has a term of 18 months, Aggregate said.

Frankfurt-listed shares in Adler closed on Thursday at 11.55 euros ($13.34).

Shares in Luxembourg-based Adler climbed on Monday after it said it would review strategic options for its real-estate portfolio, having received approaches from potential buyers.

However, the shares subsequently fell back after short seller Viceroy Research accused Adler of overstating its property values. Adler has rejected the claims.

Aggregate has a 26.6% stake in Adler, according to Aggregate's website.
