This was evident in Sinopec's annual results. In 2012, Sinopec's exploration and production segment reported an operating margin of 27.2%. On the other hand, its marketing segment, which was the biggest contributor to sales, operated with a margin of just 2.9%.
In its most recent results for the nine months ending in September 2013, Sinopec revealed that its marketing segment was responsible for 35% of its operating profits. On the other hand, its exploration and production arm contributed 60% to the company's operating profits.
By divesting from the lower-margin business and investing in the higher-margin operation, Sinopec can considerably improve its profitability in the future.
Meanwhile, analysts have speculated that PetroChina might accelerate its divestiture program in response to Sinopec's sale. However, PetroChina will mainly focus on selling its infrastructure assets as, unlike Sinopec, PetroChina's oil marketing operations consist of fewer and less lucrative retail outlets. In mid-2013, PetroChina revealed that it owns more than 20,000 gas stations.highlighted the fact that Sinopec's 30,000 gas stations are seriously undervalued. With the new investment, these stations, and the retail shops on them, can be revamped. That could improve their profitability.
