PEMEX
We are the most important company in Mexico and one of the largest in Latin America, and our success is reflected in our dedication to the future of Mexico. As the largest tax contributor to the Mexican government, the income we generate helps support all three levels of government: federal, state and municipal. We directly and indirectly participate in the economic and social development of our country. Our operations are geographically dispersed throughout Mexico, and we have presence in almost every state.
