Abacus Group previously used Morgan Stanley to advise on the internalisation of Abacus Storage King, and the firm is now running the selldown process. Sources indicate the almost 20% stake in the listed self-storage REIT is being carved up, with around half expected to go to billionaire-backed interests and the rest to institutional investors.
The parcel is reportedly being marketed as an imminent block trade, rather than a slow drip into the market. That structure lets Abacus Group cleanly exit in size without crashing the share price.
Under the mooted deal, billionaire-linked interests are expected to take roughly half the stake, while institutions absorb the balance through a placement. Those interests already control about 40% of Abacus Storage King directly, so the new purchase would lift that position to a clearly larger, more influential holding.
For institutions, the placement offers rare, immediate scale in a tightly held $1.84bn vehicle. For Abacus Group, the move crystallises value from its strategic holding and simplifies its own balance sheet post-internalisation.
The timing matters because Abacus Storage King has only just shifted to a fully internal management model, changing how fees, governance and alignment work. A larger anchor investor stepping up at that moment signals strong conviction in the asset, even as it concentrates power in fewer hands.
Market observers say the emerging ownership profile will entrench a dominant shareholder alongside a new cohort of long-only institutions. That tension between concentrated control and broader institutional backing now shapes the next phase of the REIT’s listed life.
