The biggest fast-food chain McDonald’s today posted Q2 2009 financial results, posting a net profit of $1.09 billion, down 8% YoY in the same quarter.

The company said operating income in the US was up 5% YoY. The company also noted operating income was up 34% in Asia Pacific, the Middle East, and in Africa.

Revenue was mainly down because of a stronger US dollar, but McDonald’s says, “In constant currencies, the company posted higher revenues, operating income and earnings per share compared with the prior year,”

McDonald’s CEO Jim Skinner said today he is pleased with the results and remains confident in the outlook for the year.
