Are Refiners’ Operating Models Aimed at Diversification?



Refiners’ operating models

Refiners’ operating incomes are mainly derived from their core operations—refining. But many are now focusing on diversifying their earnings models to shield themselves from the volatile refining environment. Phillips 66 (PSX) leads the pack, with just 36% of its total operating income coming from its refining segment.

Notably, PSX derives 15% from its midstream segment, 35% from marketing segment, 21% from chemicals, with the remaining percentage attributable to “corporate and other” activities during the first nine months of 2016.

Marathon Petroleum (MPC) also has a diversified operating model. MPC derives 34% and 31% of operating income of midstream and marketing segments, respectively. Valero Energy’s (VLO) operating income is predominantly derived from the refining segment.
