Oil price stability in a growing market
-
Executives said they were ‘reluctant’ to roll back price gains after a painful 18-month change to the oil charging model.
-
The strategy is to remain selective to ensure volume flow while maintaining a service-based cost structure regardless of base oil price cycles.
The impact of the Middle East conflict on performance and demand
-
The conflict did not cause operational disruptions but caused a ‘temporary pop’ in US manufacturing as customers prioritized closer supply chains.
-
The rising cost of diesel is largely offset by the monthly re-imbursement fee, making the impact of the Environmental Works negligible.
Changing the cadence of Refinery and Industrial Services
-
Current refining activity is characterized by ‘stops’ rather than major shifts as customers increase production of high-quality fuel.
-
The management does not include a major recovery of the change in the guidance of the second half, to maintain the year-to-year projections of this sub-section.
