Market overview and outlook Bristow operating revenue impacted by 27% drop in year over year oil and gas revenue; down 1% sequentially from Q4 Asia Pacific and U.S. GoM markets were challenged by reductions in utilization and completion of contracts Bristow is capitalizing on our global S-92 fleet to service critical needs for new and existing clients worldwide The June 2016 quarter oil and gas results are indicative of the next three quarters’ expected performance with upside from cost reduction initiatives offset by foreign currency exchange rate depreciation Improving our liquidity through: Finalizing deferral of ~$95 million of oil and gas aircraft capex Pursuing prudent financing alternatives to bridge liquidity; SAR assets remain attractive financing sources of capital Upside from new contract wins and full U.K. SAR contribution expected to begin to impact results in FY18

FX headwinds intensify due to Brexit; minimal impact from Nigerian naira Brexit is not expected to have any operational impact on our North Sea business The depreciation of the GBP in late June had limited impact on our Q1 FY17 operating results as the change occurred late in the quarter If the USD/GBP rate persists at the June 30 level for the remainder of FY17, the translation of our GBP denominated operating results would decrease adjusted EBITDAR by ~$15 - 20 million Q1 FY17 adjusted EBITDAR was negatively impacted by $6.3 million of balance sheet FX revaluations, predominately GBP The devaluation of the Nigerian naira had a minimal impact on our Q1 FY17 results

Oil and gas rotary revenue declines are partially offset by U.K. SAR and fixed wing contribution Oil and gas: Five LACE renewal for five years in ECR beginning Q1 FY18 1½ LACE for five years in ECR beginning Q3 FY17 Two LACE on short term contracts in Norway Ending of several contracts in AMR and APR LACE rate reduction SAR: U.K. SAR continues to perform as expected with only ~$115 million of capital spend remaining as of today Began offering oil and gas SAR service in Nigeria with one AW139 Fixed wing: addition of new routes in both Airnorth and Eastern 96% 2% 88% 9% 3% Operating revenue by business line $ in millions 2% 76% 13% 11% 72% 14% 14%

Anticipated deferral of ~$95 million of oil and gas aircraft capex into FY19 and beyond 30 64 Deferral out of FY17/FY18 and into future periods We are finalizing an over 40% reduction in aircraft capital expenditures in FY17 and FY18 We sold six aircraft and other assets for total proceeds of ~$12 million in Q1 FY17

Updated FY17 guidance 1) FY17 guidance assumes FX rates as of June 30, 2016 2) EBITDAR excludes corporate overhead allocations and is consistent with financial reporting FY17 guidance as of June 30, 20161 U.K. SAR Revenue ~$195M - $225M G&A expense ~$195M - $215M EBITDAR2 ~$85M - $105M Depreciation expense ~$110M - $130M Eastern Revenue ~$120M - $135M Rent expense ~$215M - $225M EBITDAR2 ~$15M - $20M Interest expense ~$35M - $45M Airnorth Revenue ~$70M - $85M Non-aircraft capex ~$50M annually EBITDAR2 ~$15M - $20M U.K. SAR guidance lowered as a result of GBP depreciation Tax rate, when adjusted for discrete items, is dependent on earnings mix between higher and lower tax rate jurisdictions; our tax strategy is proven and fully compliant with all relevant jurisdictional authorities

Bristow has proven resources to survive this downturn as a global sector leader Primary focus remains on reinforcing Target Zero programs and improving safety performance The P&L impact of the GBP depreciation will be realized in future periods if the USD/GBP rate remains at current levels or depreciates further The June 2016 quarter oil and gas results are expected to be indicative of the next three quarters’ expected performance with upside from cost reduction initiatives offset by foreign currency exchange rate depreciation Bristow has the tools to survive this downturn as a global sector leader We have been successful in improving liquidity through deferring/cancelling capex and opex reductions Covenant relief continues to provide us with ample flexibility Multiple financing options anchored by our mostly unsecured U.K. SAR assets and global owned fleet with ~$2.0 billion estimated value

Bristow Value Added (BVA) BVA is computed by subtracting a capital charge (10.5%) for the use of gross invested capital from after tax operating cash flow. GCF Return % is based on trailing twelve months after tax operating cash flows (Gross Cash Flow) over average quarterly gross invested capital (Gross Operating Assets). Refer to slide 36 for additional details.

NOTE: The gray shaded area represents the range of FMV with and without the impact of leased aircraft (upper range includes leased aircraft and related NPV of lease payments; lower range excludes FMV of leased aircraft as well as the NPV of lease payments). The company derives market value from observable market data if available and may require utilization of estimates, applications of significant judgment and reliance upon valuation specialists’ and third party analysts’ reports. When using third party reports, the market value is as of the date of such report and is not updated to reflect factors that may impact the valuation since the date of such report, including fluctuations in foreign currency exchange rates, oil and gas prices, and the balance of supply and demand. There is no assurance that market value of an asset represents the amount that the Company could obtain from an unaffiliated third party in an arm’s length sale of the asset, the fleet, or the Company.
