Spallis – Equity

Results: Increased contracted NOI by +38% within 13 months after acquisition. Property sold for a price exceeding the initial business plan, 2 years earlier than expected, resulting in an earnout payment to the seller.

Cassiopée – Equity

AD Portfolio – Turnaround for Lenders

At Closing: 23 light industrial properties totalling 80,273 m2 with an average remaining lease duration of less than 3 years and litigation between tenant and landlord. Acquisition of PropCo assuming a 100%+ LTV loan in default after agreeing a new business plan and a loan extension with lenders.


Asset Management: Negotiated an end to the outstanding litigation process with the tenant. Sold 15 non-core assets in 2.5 years. Implemented a capex program on the 8 assets of the core portfolio. Extended leases to obtain an 8.2 years average lease duration for the core portfolio.
