S2G Investments Appoints Brian O’Connor as Managing Director and Co-Head of Special Opportunities Strategy

Expanded leadership team strengthens S2G’s ability to deliver structured finance solutions for asset-backed businesses

CHICAGO--(BUSINESS WIRE)--S2G Investments ("S2G"), a multi-stage investment firm focused on scaling solutions across food & agriculture, energy, and oceans, today announced the appointment of Brian O’Connor as Managing Director and Co-Head of Special Opportunities. O’Connor, who will officially join the firm in May, brings more than two decades of experience in infrastructure and energy investing and will play a key role in building S2G’s Special Opportunities platform as it continues to scale.

O’Connor joins S2G from Global Infrastructure Partners, where he served as a Partner leading credit transactions across the power, renewables, energy transition, and digital sectors. Previously, he spent 12 years at Ares Management, helping to build and lead a team focused on structured finance for the infrastructure sector, overseeing approximately $3 billion in transactions across senior debt, mezzanine, preferred equity, and common equity. His career also includes nine years at EIG Global Energy Partners, where he invested in power generation through mezzanine, senior debt, and structured equity.

At S2G, O’Connor will co-lead the Special Opportunities strategy alongside Managing Director Andrea Woodside, focusing on sourcing, structuring, and managing investments across the evolving energy and infrastructure landscape. The Special Opportunities strategy complements S2G’s growth equity investing by providing flexible, structured finance solutions for asset-oriented companies and projects.

"We believe the bridge between affordable, flexible energy and the enterprises and communities that need it isn’t just technology, but creative and structured capital," said O’Connor. "By providing fit-for-purpose financing, we can support the deployment of 21st-century business models in energy and infrastructure. I look forward to partnering with S2G to advance that vision."

S2G’s Special Opportunities strategy is designed to enable growth while offering downside protection. The team leverages extensive domain knowledge to invest in businesses or projects supported by hard assets, contracts, and cash flows, typically targeting investment sizes of $10 million to $40 million. Through senior secured debt, delayed draw term loans, and structured equity, S2G targets the underserved 'Missing Middle' gap between venture capital and traditional large-cap infrastructure financing.

"Bringing in a leader of Brian’s caliber, with his track record of managing infrastructure portfolios, significantly elevates our ability to underwrite complex industrial assets," said Sanjeev Krishnan, Managing Partner at S2G. "His arrival signals our commitment to ensuring companies have a partner that understands how to finance critical physical assets. His deep roots in energy and infrastructure will be instrumental in expanding our Special Opportunities platform and executing high-impact transactions."

The appointment of O’Connor follows a period of significant momentum for S2G as it continues to deploy capital into essential sectors that underpin the global economy. By expanding its senior leadership team, S2G reinforces its position as a partner for companies advancing more efficient and resilient industrial systems.
