On May 10, 2011, Bristow Group Inc. (the “Company”) issued a press release which summarized its financial results for the three-month period and fiscal year ended March 31, 2011 (the “Financial Results”). This press release was issued in anticipation of a conference call and Q&A session starting at 10:00 a.m. ET (9:00 CT) on Wednesday, May 11, 2011, to review the Financial Results. A copy of the press release is furnished with this report as Exhibit 99.1, and is incorporated herein by reference.

The press release includes certain “non-GAAP financial measures” under Regulation G of the Securities Exchange Act of 1934 (the “Exchange Act”), including Earnings before Interest, Income Tax and Depreciation and Amortization (“EBITDA”). Additionally, our operating income, EBITDA, net income and diluted earnings per share for the three months ended March 31, 2011 and 2010 and the fiscal years ended March 31, 2011 and 2010 in this release have been presented in certain instances excluding special items detailed in the press release. Management believes that such non-GAAP financial measures are important metrics for evaluating our operating performance, and they provide investors with additional information that is not directly available in a GAAP presentation. Such non-GAAP financial measures are useful to investors as they eliminate items that are not a function of our current operating performance and affect our GAAP results regardless of performance. In addition, certain of these items may vary significantly from period to period and may have a disproportionate effect in a given period, which may affect the comparability of the results. Such non-GAAP measures should not be viewed as an alternative to our GAAP financial statements, but should be read as a supplement to, and in conjunction with, our GAAP financial statements.
