Petro's revenue grew by 57%, but operating profit fell behind In the six-month report that ended at the end of September 1405, Petrochemical Transport Engineering Company increased its operating profit to 386 billion tomans, which is an increase of 57% compared to the same period last year. However, the growth in direct and management expenses did not allow this increase in revenues to become an increase in operating profit, and the company's operating profit reached 71 billion eights, a decrease of about 1 percent.
