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 and, for the avoidance of doubt, include all statements herein regarding the Company's financial targets for Calendar Years 2023 and 2024 and operational outlook. These forward-looking statements include statements regarding expectations with respect to the Irish Coast Guard Aviation Service contract and related procurement process. 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 (including the Company's financial targets for Calendar Years 2023 and 2024 and operational outlook) 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 except as may be required by applicable law. Risks that may affect forward-looking statements include, but are not necessarily limited to, those relating to: public health crises, such as pandemics (including COVID-19) and epidemics, and any related government policies and actions; any failure to effectively manage, and receive anticipated returns from, acquisitions, divestitures, investments, joint ventures and other portfolio actions; our inability to execute our business strategy for diversification efforts related to, government services, offshore wind, and advanced air mobility; our reliance on a limited number of customers and the reduction of our customer base as a result of consolidation and/or the energy transition; the possibility that we may be unable to maintain compliance with covenants in our financing agreements; global and regional changes in the demand, supply, prices or other market conditions affecting oil and gas, including changes resulting from a public health crisis or from the imposition or lifting of crude oil production quotas or other actions that might be imposed by the Organization of Petroleum Exporting Countries (OPEC) and other producing countries; 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; the possibility of significant changes in foreign exchange rates and controls; potential effects of increased competition and the introduction of alternative modes of transportation and solutions; 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 and regulations and policies, including, without limitation, actions of the governments that impact oil and gas operations or favor renewable energy projects; 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 portions of our fleet may be grounded for extended periods of time or indefinitely (including due to severe weather events); 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 where we are seeking contracts could adversely affect or lead to modifications of the procurement process or that such reductions in spending could adversely affect search and rescue (“SAR”) contract terms or otherwise delay service or the receipt of payments under such contracts., our contracts with the Bureau of Safety and Environmental Enforcement (“BSEE”) or delays in receiving payments under such contracts; the effectiveness of our environmental, social and governance initiatives; the impact of supply chain disruptions and inflation and our ability to recoup rising costs in the rates we charge to our customers; and our reliance on a limited number of helicopter manufacturers and suppliers. If one or more of the foregoing risks materialize, or if underlying assumptions prove incorrect, actual results may vary materially from those expected. 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 Transition Report on Form 10-KT for the year ended December 31, 2022 (the “Transition 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 Transition 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 www.sec.gov.

3 Non-GAAP Financial Measures Reconciliation 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. Each of these measures, detailed below, have limitations, and are provided in addition to, and not as an alternative for, and should be read in conjunction with, the information contained in our financial statements prepared in accordance with GAAP (including the notes), included in our filings with the SEC and posted on our website. 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. Management believes that the use of EBITDA and Adjusted EBITDA is meaningful to investors because it provides information with respect to our ability to meet our future debt service, capital expenditures and working capital requirements and the financial performance of our assets without regard to financing methods, capital structure or historical cost basis. Neither EBITDA nor Adjusted EBITDA is a recognized term under GAAP. Accordingly, 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 management’s discretionary use, as they do not consider 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. There are two main ways in which foreign currency fluctuations impact on the Company’s reported financials. The first is primarily non-cash foreign exchange gains (losses) that are reported in the Other Income line on the Income Statement. These are related to the revaluation of balance sheet items, typically do not impact cash flows, and thus are excluded in the Adjusted EBITDA presentation. The second is through impacts to certain revenue and expense items, which impact the Company’s cash flows. The primary exposure is the GBP/USD exchange rate. This presentation provides a reconciliation of net income (loss), the most directly comparable GAAP measure, to EBITDA and Adjusted EBITDA (in thousands, unaudited). The Company is unable to provide a reconciliation of forecasted Adjusted EBITDA for Calendar Years 2023 and 2024 included in this presentation to projected net income (GAAP) for the same period because components of the calculation are inherently unpredictable. The inability to forecast certain components of the calculation would significantly affect the accuracy of the reconciliation. Additionally, the Company does not provide guidance on the items used to reconcile projected Adjusted EBITDA due to the uncertainty regarding timing and estimates of such items. Therefore, the Company does not present a reconciliation of forecasted Adjusted EBITDA to net income (GAAP) for Calendar Years 2023 and 2024. Free Cash Flow represents the Company’s net cash provided by operating activities less maintenance capital expenditures. In prior periods, the Company’s Free Cash Flow was calculated as net cash provided by (used in) operating activities plus proceeds from disposition of property and equipment less purchases of property and equipment. Management believes that the change in the Company’s free cash flow calculation, as presented herein, better represents the Company’s cash flow available for discretionary purposes, including growth capital expenditures. Adjusted Free Cash Flow is Free Cash Flow adjusted to exclude costs paid in relation to a PBH maintenance agreement buy-in, reorganization items, costs associated with recent mergers, acquisitions and ongoing integration efforts, as well as other special items which include nonrecurring professional services fees and other nonrecurring costs or costs that are not related to continuing business operations. Management believes that Free Cash Flow and Adjusted Free Cash Flow are meaningful to investors because they provide information with respect to the Company’s ability to generate cash from the business. The GAAP measure most directly comparable to Free Cash Flow and Adjusted Free Cash Flow is net cash provided by operating activities. Since neither Free Cash Flow nor Adjusted Free Cash Flow is a recognized term under GAAP, they should not be used as an indicator of, or an alternative to, net cash provided by operating activities. 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 Free Cash Flow and Adjusted Free Cash Flow may differ from the methods used by other companies to calculate their free cash flow. As such, they may not be comparable to other similarly titled measures used by other companies 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. The GAAP measure most directly comparable to Net Debt is total debt. Since Net Debt is not a recognized term under GAAP, it should not be used as an indicator of, or an alternative to, total debt. Management uses Net Debt to determine the Company’s outstanding debt obligations that would not be readily satisfied by its cash and cash equivalents on hand. Management believes this metric is useful to investors in determining the Company’s leverage position since the Company has the ability to, and may decide to, use a portion of its cash and cash equivalents to reduce debt. 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.

However, with little equipment spare capacity, net pricing gains to service companies should account for much of the 2023 capex increase.” — J. David Anderson, CFA Barclays Research CONTRACTION PHASE: From 1981 to 1986 spending fell by 56% TRANSFORMATION PHASE: Following the 1986 crash, the 1990s were marked by cost reduction and industry bankruptcies/consolidation GROWTH PHASE: The 2000s up until 2014 were without a doubt the 'golden years' of the offshore energy industry CONTRACTION PHASE: From 2014 to 2020 spending fell by 55% TRANSFORMATION/ GROWTH PHASE

22 Outlook By Lines of Service Please refer to Cautionary Statement Regarding Forward-Looking Statements on slide 3, which discusses risks that could cause actual results to differ materially. (1) As preferred bidder, Bristow entered the final stages of the Irish Department of Transportation's procurement process. As such, there can be no assurance that the Irish Department of Transport will award Bristow such contract or that such contract will be finalized. Offshore Energy Services We believe the offshore energy market has entered a multi-year growth cycle. Given our sector’s late cycle exposure and the lag effect involving new projects, this should become evident in our financial results in 2023 and beyond. A tighter equipment market, constrained global labor force, and inflationary cost pressures should drive meaningful rate increases. Europe region: • New Norway four-year SAR contract expected to start in September 2023 with full year impacts further benefiting 2024 • A crowded competitive landscape will continue to be a challenge in our U.K. offshore energy business • A stronger U.S. dollar relative to the British pound sterling and Norwegian krone would adversely impact the financial results in this region Americas region: • Increased customer activity and the commencement of previously awarded contracts are expected to drive increased utilization in the U.S. Gulf of Mexico and Brazil with additional tender activity expected in 2024 • Guyana revenues declined due to the end of a customer contract at year-end 2022 Africa region: • Increased market activity and the return of a significant customer contract continue to drive better results in Nigeria • Africa is expected to be a growth region for Bristow, well into 2024 Business expanding based on new contract awards and an acquisition Full year impact of operations in the Falkland Islands, the Netherlands and the Dutch Caribbean will benefit financial results in 2023 UKSAR2G contract transition will begin in 2024 with completion expected in 2026 Announced as the preferred bidder for Irish Coast Guard contract; if such contract is finalized, it is expected to be a 10-year contract commencing at the end of 2024(1) A stronger U.S. dollar relative to the British pound sterling would adversely impact financial results. Government Services We believe the financial performance of this business will be stronger in 2023 compared to 2022 We are seeing continued growth from charter revenues, expected to continue through 2023. Pilot shortages in Australia remain a challenge. Fixed Wing & Other Services

26 Seasonality $294 $299 $304 $293 $0 $200 $400 Jun 2022 Sept 2022 Dec 2022 Mar 2023 $ M ill io n s Operating Revenues Certain of our operations are subject to seasonality: 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 North Sea operations are subject to seasonality as drilling activity is lower during the winter months due to harsh weather conditions and shorter days.
