Bristow Group Inc

In general, the winter months are seasonally our lowest revenue periods, with fewer daylight hours resulting in reduced flight hours in our Offshore Energy Services segment and fewer rescues in our Government Services segment.

We are one of the largest providers of aviation services in the North Sea, when there are harsh weather conditions and geographically concentrated offshore facilities. Our North Sea operations are subject to seasonality as drilling activity is lower during the winter months due to harsh weather conditions and shorter days.

Our operations in the U.S. are subject to seasonality where fewer hours of daylight in the winter months may result in fewer flight hours. The months of December through February in the U.S. Gulf of America typically have more days of adverse weather conditions than the other months of the year. Additionally, June through November is tropical storm season in the U.S. Gulf of America. During a tropical storm, we are unable to operate in the area of the storm; however, flight activity may increase immediately before and after a storm due to the evacuation and return of offshore workers.

Operations in Nigeria are subject to seasonality as the Harmattan, a dry and dusty trade wind, blows between the end of December and the middle of February. At times when the heavy amount of dust in the air severely limits visibility, our aircraft are unable to operate.

Our operations in Australia experience fewer passengers during the wet season from December through March.
