Case Study: Ultramar Diamond Shamrock achieves increased market share and faster access to strategic data with Informatica

Leading refinery company increases market share and improves realization of sales with Informatica

Ultramar Diamond Shamrock, part of Valero Energy Corporation — a global refiner with 20,000 employees, $55 billion in annual revenue, and 4,700 retail sites — needed to lower data management costs, grow refining revenues, and improve finance and accounting controls to support better decision-making.

By deploying Informatica PowerCenter alongside SAP BW to bridge SAP and non‑SAP data, UDS created a unified analytic architecture that became mission‑critical. The solution delivered faster access to richer data for strategic analysis and drove measurable business outcomes: increased market share, higher receivables through improved contract fulfillment, and better realization of sales.
