Independent Refiner Secures Operational Stability and Scalability Through Rapid Post-Merger IT Integration

The Challenge

A major independent refining company, operating a complex network with over 400,000 bbl/sd capacity, required a seamless IT and operational transition following a $350 million acquisition of a complex West Coast refinery and its associated logistics assets. The primary goal was to ensure a zero-interruption transfer of ownership while migrating critical commercial and inventory management functions.

The transaction involved high-stakes complexities, including the management of a change-in-control (CIC) process and a transition service agreement (TSA) with the seller. The client faced a short timeline to decouple from the seller's legacy environment and integrate the new asset into their corporate architecture. They needed an advisory partner with deep senior-level expertise in energy and a proven agile implementation approach to refinery yield accounting and downstream hydrocarbon supply chains. Opportune was uniquely qualified to lead this transition, having successfully navigated nine refinery acquisitions.

The Solution

Opportune rapidly deployed a specialized task force to design and execute a comprehensive M&A IT transition playbook. Our professionals modeled and structured a detailed execution plan that successfully transitioned all hydrocarbon commercial and inventory management activities from the seller’s legacy systems into the client’s existing infrastructure.

To mitigate risk, Opportune integrated its proprietary "M&A Methodology" with the client’s internal tools to create a scalable execution playbook for future acquisitions. We led high-impact workshops between IT, business units, and the seller to finalize the TSA and CIC plans, ensuring every application and license was accounted for. By prioritizing the client-centric benefit of operational continuity, we optimized the application rationalization process, allowing the client to realize immediate cost savings while ensuring the refinery remained fully operational throughout the change in ownership.

Business Impact

  • Achieved 100% Operational Continuity during the Change-in-Control (CIC) for a 149,000 bbl/d refining asset and cogeneration facility.
