Bristow Group Inc.

Critical accounting estimates are defined as those that are affected by significant judgments and uncertainties which could potentially result in materially different accounting under different assumptions and conditions. The Company has prepared the financial statements in conformity with GAAP, which requires management to make estimates and assumptions that affect the reported amounts in the financial statements. Actual results could differ from those estimates under different assumptions or conditions. The following critical accounting estimates could potentially result in a material impact to our financial condition or operating results. The Company believes that of its significant accounting policies, as discussed in Note 1 to the consolidated financial statements included in this Annual Report on Form 10-K, the following involve a higher degree of judgment and complexity.

Taxes

Our annual tax provision is based on expected taxable income, statutory rates and tax planning opportunities available to us in the various jurisdictions in which we operate. The determination and evaluation of our tax provision and tax positions involves the interpretation of the tax laws in the various jurisdictions in which we operate and requires significant judgment and the use of estimates and assumptions regarding significant future events such as the amount, timing and character of income, deductions and tax credits. Changes in tax laws, regulations, agreements, tax treaties and foreign currency exchange restrictions or our level of operations or profitability in each jurisdiction would impact our tax liability in any given year.

We maintain reserves for estimated income tax exposures in jurisdictions of operation. The expenses reported for these taxes, including our annual tax provision, include the effect of reserve provisions and changes to reserves that we consider appropriate, as well as related interest. We believe that an appropriate liability has been established for estimated exposures. However, actual results may differ materially from these estimates.

As of December 31, 2025, we have recognized deferred tax assets for certain attributes we expect to be realizable. Our ability to realize the benefit of our deferred tax assets requires us to achieve certain future earnings levels. If we are unable to benefit from our deferred tax assets, valuation allowances will be established following the “more-likely-than-not” criteria.

As of each reporting date, management considers new evidence, both positive and negative, that could affect its view on the future realization of deferred tax assets.

Pension Benefits

Pension obligations for the defined benefit pension plans are actuarially determined. The obligations are measured using assumptions about the future. We evaluate our assumptions periodically and adjust these assumptions as necessary.

Three critical assumptions are the expected long-term rate of return on plan assets, the assumed discount rate and the mortality rate. The assumption for the estimated long-term rate of return on plan assets is evaluated by our actuarial advisor based on future expectations of investment returns for the asset classes held by the plans’ investment portfolios. We utilize a British pound sterling denominated AA corporate bond index as a basis for determining the discount rate for our UK plans. We base mortality rates utilized on actuarial research on these rates. Changes in these and other assumptions used in the actuarial computations could impact our projected benefit obligations, pension liabilities, pension expense and other comprehensive income.
