StoneShield to Raise Exolum Stake to 20% via Acquisition from OMERS

In a move that strengthens private investment in European energy infrastructure, StoneShield Capital has signed an agreement to acquire a 15% stake in Exolum from OMERS, raising its total holding to approximately 20%. According to reports, the remaining 10% of the OMERS stake will be acquired separately by a leading global investment institution with over $100 billion in assets under management. The transaction is expected to close in the third quarter of 2026, subject to necessary regulatory approvals.

This acquisition comes as Spain's trade balance showed resilience, recording a deficit of -4.4 billion euros against expectations of -5.6 billion euros per market data on May 19, 2026. StoneShield's decision to consolidate its position reflects investor confidence in energy logistics as OMERS rotates capital after a decade of ownership. Exolum remains a pivotal player in the storage and transport of refined products and chemicals in Europe, making it a strategic asset amid shifting energy supply chains.

Investors should monitor Spanish regulatory approvals over the coming months as a primary catalyst for the deal's closure by Q3 2026. Markets are also eyeing broader European economic indicators that impact infrastructure valuations, such as the Euro Area trade balance which recently posted a 7.8 billion euro surplus (as of May 19, 2026). The identity of the global institution acquiring the final portion of the OMERS stake remains a key detail to watch for its impact on Exolum's future governance.
