Stoneshield Capital: 15% Exolum Stake Acquisition Expands Energy Logistics Investment

Stoneshield Capital announced that it has signed an agreement to acquire a 15% stake in global energy logistics company Exolum from OMERS, increasing its overall ownership position in the business. The transaction builds on Stoneshield’s initial investment in Exolum made in January 2026, when it acquired a 4.93% stake in the company.

The remaining 10% portion of OMERS’ roughly 25% holding is being acquired separately by another global investment firm managing more than $100 billion in assets. Financial terms of the transactions were not disclosed.

Headquartered in Spain, Exolum operates energy transportation, storage, and distribution infrastructure across multiple international markets. The company manages a 4,000-kilometer transmission pipeline network in Spain and an additional 2,000 kilometers of pipeline infrastructure in the United Kingdom. Exolum also owns 68 storage terminals with more than 11 million cubic meters of capacity and serves more than 48 airports globally, including Heathrow, Gatwick, Stansted, Madrid, Barcelona, Lisbon, Lima, and Charles de Gaulle airports.

Exolum has increasingly focused on supporting the global energy transition through investments tied to lower-carbon fuels and future energy infrastructure. The company employs more than 2,300 people worldwide and generates annual revenue exceeding €1.3 billion.

Following completion of the transaction, Stoneshield’s total ownership stake in Exolum will rise to approximately 20%. Stoneshield Capital will also assume three of OMERS’ existing board seats, while the second investor will take the remaining two seats.

The deal is expected to close during the third quarter of 2026, subject to customary regulatory approvals and closing conditions.
