2 Cautionary Statement Regarding Forward-Looking Statements This presentation contains “forward-looking statements.” Forward-looking statements represent Bristow Group Inc.’s (the “Company”) current expectations or forecasts of future events. Forward-looking statements generally can be identified by the use of forward-looking terminology such as “may,” “will,” “expect,” “intend,” “estimate,” “anticipate,” “believe,” “project,” or “continue,” or other similar words. These statements are made under the safe harbor provisions of the Private Securities Litigation Reform Act of 1995, reflect management’s current views with respect to future events and therefore are subject to significant risks and uncertainties, both known and unknown. The Company’s actual results may vary materially from those anticipated in forward-looking statements. The Company cautions investors not to place undue reliance on any forward-looking statements. Forward-looking statements speak only as of the date of the document in which they are made. The Company disclaims any obligation or undertaking to provide any updates or revisions to any forward-looking statement to reflect any change in the Company’s expectations or any change in events, conditions or circumstances on which the forward-looking statement is based that occur after the date hereof. Risks that may affect forward-looking statements include, but are not necessarily limited to, those relating to: the COVID-19 pandemic and related economic repercussions have resulted, and may continue to result, in a decrease in the price of and demand for oil, which has caused, and may continue to cause, a decrease in the demand for our services; expected cost synergies and other benefits of the merger (the “Merger”) of the entity formerly known as Bristow Group Inc. (“Old Bristow”) and Era Group Inc. (“Era”) might not be realized within the expected time frames, might be less than projected or may not be realized at all; the ability to successfully integrate the operations, accounting and administrative functions of Era and Old Bristow; managing a significantly larger company than before the completion of the Merger; diversion of management time on issues related to integration of the companies; the increase in indebtedness as a result of the Merger; operating costs, customer loss and business disruption following the Merger, including, without limitation, difficulties in maintaining relationships with employees and customers, may be greater than expected; our reliance on a limited number of customers and the reduction of our customer base as a result of bankruptcies or consolidation; the possibility that we may be unable to maintain compliance with covenants in our financing agreements; fluctuations in worldwide prices of and demand for oil and natural gas; fluctuations in levels of oil and natural gas exploration, development and production activities; fluctuations in the demand for our services; the possibility that we may impair our long-lived assets and other assets, including inventory, property and equipment and investments in unconsolidated affiliates; our ability to implement operational improvement efficiencies with the objective of rightsizing our global footprint and further reducing our cost structure; the possibility of significant changes in foreign exchange rates and controls, including as a result of the U.K. having exited from the European Union (“E.U.”) (“Brexit”); the impact of continued uncertainty surrounding the effects Brexit will have on the British, E.U. and global economies and demand for oil and natural gas; potential effects of increased competition; the risk of future material weaknesses we may identify while we work to align policies, principles, and practices of the combined company following the Merger or any other failure by us to maintain effective internal controls; the possibility that we may be unable to re-deploy our aircraft to regions with greater demand; the possibility of changes in tax and other laws regulations, and policies, including, without limitation, actions of the Biden Administration that impact oil and gas operations or favor renewable energy projects in the U.S.; the possibility that we may be unable to dispose of older aircraft through sales into the aftermarket; general economic conditions, including the capital and credit markets; the possibility that segments of our fleet may be grounded for extended periods of time or indefinitely; the existence of operating risks inherent in our business, including the possibility of declining safety performance; the possibility of political instability, war or acts of terrorism in any of the countries where we operate; the possibility that reductions in spending on aviation services by governmental agencies could lead to modifications of our search and rescue (“SAR”) contract terms with the U.K. government, our contracts with the Bureau of Safety and Environmental Enforcement or delays in receiving payments under such contracts; and our reliance on a limited number of helicopter manufacturers and suppliers capabilities, development, certification, marketing, and future operations of Electra’s hybrid-electric aircraft, the Company’s purchase of aircraft from Electra, and the anticipated benefits of the collaboration between the Company and Electra. You should not place undue reliance on our forward-looking statements because the matters they describe are subject to known and unknown risks, uncertainties and other unpredictable factors, many of which are beyond our control. Our forward-looking statements are based on the information currently available to us and speak only as of the date hereof. New risks and uncertainties arise from time to time, and it is impossible for us to predict these matters or how they may affect us. We have included important factors in the section entitled “Risk Factors” in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2021 (the “Annual Report”), which we believe over time, could cause our actual results, performance or achievements to differ from the anticipated results, performance or achievements that are expressed or implied by our forward-looking statements. You should consider all risks and uncertainties disclosed in the Annual Report and in our filings with the United States Securities and Exchange Commission (the “SEC”), all of which are accessible on the SEC’s website at

3 Non-GAAP In addition to financial results calculated in accordance with U.S. generally accepted accounting principles (“GAAP”), this presentation includes certain non-GAAP measures including EBITDA, Adjusted EBITDA, Net Debt, Free Cash Flow and Adjusted Free Cash Flow. EBITDA and Adjusted EBITDA are presented as supplemental measures of the Company’s operating performance. EBITDA is defined as Earnings before Interest expense, Taxes, Depreciation and Amortization. Adjusted EBITDA is defined as EBITDA further adjusted for special items that occurred during the reporting period and noted in the applicable reconciliation. Since neither EBITDA nor Adjusted EBITDA is a recognized term under GAAP they should not be used as an indicator of, or an alternative to, net income as a measure of operating performance. In addition, EBITDA and Adjusted EBITDA are not intended to be measures of free cash flow available for discretionary use, as they do not take into account certain cash requirements, such as debt service requirements. Because the definitions of EBITDA and Adjusted EBITDA (or similar measures) may vary among companies and industries, they may not be comparable to other similarly titled measures used by other companies. Free Cash Flow represents the Company’s net cash provided by operating activities plus proceeds from disposition of property and equipment, less expenditures related to purchases of property and equipment. Adjusted Free Cash Flow is Free Cash Flow adjusted to exclude professional services fees and other costs paid in relation to the Merger, the implementation of fresh-start accounting and the voluntary petitions filed by Old Bristow and certain of its subsidiaries on May 11, 2019, in the U.S. Bankruptcy Court for the Southern District of Texas, Houston Division seeking relief under Chapter 11 of Title 11 of the U.S. Code (the “Chapter 11 Cases”). Management believes that the use of Adjusted Free Cash Flow is meaningful as it measures the Company’s ability to generate cash from its business after excluding cash payments for special items. Management uses this information as an analytical indicator to assess the Company’s liquidity and performance. However, investors should note numerous methods may exist for calculating a company's free cash flow. As a result, the method used by management to calculate Adjusted Free Cash Flow may differ from the methods used by other companies to calculate their free cash flow. The Company also presents Net Debt, which is a non-GAAP measure, defined as total principal balance on borrowings less unrestricted cash and cash equivalents. Each of these non-GAAP measures has limitations and therefore should not be used in isolation or as a substitute for the amounts reported in accordance with GAAP. A reconciliation of each of EBITDA, Adjusted EBITDA, Adjusted EBITDA excluding gains or losses on asset dispositions, Free Cash Flow, Adjusted Free Cash Flow, and net debt is included elsewhere in this presentation. Pro Forma This presentation also includes certain financial information provided on a “pro forma” basis to reflect the consummation of the Merger and certain related transactions. The pro forma results were prepared by combining the pre-merger results of operations of Bristow Group and Old Era without further adjustment. As a result, we believe our pro forma information are non-GAAP financial measures. Pro forma financial information does not necessarily reflect the actual results that we would have achieved had the pro forma transactions been consummated on the date or dates indicated nor does it reflect our potential future results.
