Begging your pardon but your math is incorrect.
If the deal is for 8,450,000 metric tons this is the correct math.

There are 7.1475121 barrels of oil in (1) metric ton

If you have 8,450,000 metric tons you need to divide that number by 7.1475121 barrels per ton

8,450,000/7.1475121= 1,182,229.55 barrels of oil.

If the deal is for 12 months that is 98,519.12 barrels per month.

At $100/barrel that is $9,851,912.92/ month, or roughly $118,222,944/year.

At 10% profit that is $11,822,294.40

50% of that is $5,911,147.2

That is the correct math and much more realistic expectations. Still, 98k barrels per month is still a lot of oil to move and will require $10m a month in financing to do it.

Without a financier for each delivery where is the money going to come from? The CEO stated that 20% monthly commitment has been achieved but that's not going to get it done.

I don't know if 10% margins are the right number. You used 16% in your math. Someone will need to be willing to leverage $118m a year to make $6-9m a year if the split is 50:50
