The largest U.S. based oil company, and the most traded oil company in the world, ExxonMobil, today announced Q4 financial earnings, and full year 2009 earnings.

Exxon reported a material 23-percent decline in Q4 profits, compared to the same period last year. The company earned a $6.05-billion profit ($1.27 per share) in Q4 2009, compared to $7.82-billion YoY. Q4 2008revenue was $84.7-billion.

In fiscal 2009, Exxon reported reasonably strong profits of $19.42-billion. That figure is significantly less than fiscal 2008 profits, down over 50-percent from $45-billion in profits in 2008. The company was able to report its strongest year in 2008 because of record crude oil prices that peaked at $147 per barrel.

In 2009, most of the company’s profits came from its product and exploration division that earned a substantial $5.78-billion operating profit.

ExxonMobil chairman Rex Tillerson said in a statement today, “ExxonMobil delivered strong business results and built on our long-term focus,”

The company said capital and exploration spending was $27.1-billion in 2009.

Production in Q4 was also up 2-percent despite weakening demand for energy in this difficult economic time.

Exxon has been criticized for not doing enough to invest more in emerging eco-friendly technologies.
