Overview The December 2016 quarter results reflect the continued pressure on our oil and gas operations due to the industry downturn; however, they were above our internal expectations Improving our liquidity runway by $630 million through: Funding of $200 million Lombard seven-year equipment financings Finalized credit agreement with Macquarie for $200 million secured equipment financing Executed commitment letter with Milestone / GE Capital Aviation Services for $230 million secured equipment financing Recent tender successes reflect our global position, reliable operations and creative solutions in oil and gas transportation and SAR While we expect offshore E&P spend to be down again in FY18 and challenging market conditions to continue, green shoots are beginning to appear

Liquidity runway including $630 million equipment financings significantly improves our financial flexibility in this downturn We expect new leased aircraft will offset rent savings from returned aircraft in the short term as we manage fleet operations We continue to reduce incremental lease costs Fully funded Lombard $200 million, five-year term, L+2.25% Macquarie $200 million, five-year term, L+5.35% Milestone/GECAS $230 million, six-year term, L+5.00% We intend to continue to return aircraft to lessors as planned in future years (first two in process) CY16 amendments to credit facilities demonstrate bank group support Capex deferrals (on top of ~$95 million FY17/18 capex deferral) Self-help Secured equipment financing Leased fleet

Updated guidance as of December 31, 2016 FY17 guidance assumes FX rates as of December 31, 2016 EBITDA excludes corporate overhead allocations consistent with financial reporting. EBITDA is a non-GAAP measure of which the most comparable GAAP measure is net income (loss). We have not provided a reconciliation of this non-GAAP forward-looking information to GAAP. The most comparable GAAP measure to EBITDA is net income (loss) which is not calculated at this lower level of our business as we do not allocate certain costs, including corporate and other overhead costs, interest expense and income taxes within our accounting system. Providing this data would require unreasonable efforts in the form of allocations of other costs across the organization. Total aircraft rent and total non-aircraft rent are inclusive of respective component of rent expense for U.K. SAR, Eastern, Airnorth plus oil and gas.

Bristow continues to execute successfully to maintain leadership position during this downturn Primary focus remains on continuing to improve upon our safety performance Like our offshore services peers, we expect offshore E&P spend to be down again in FY18; we remain laser focused on improving our essential service for our clients as we anticipate offshore spend to increase in FY19/20 Unlike our offshore services peers, we have diversified business lines that provide relatively stable cash flow through this prolonged downturn Funding of $200 million Lombard financings plus anticipated $430 million secured financings improve liquidity by terming out bank debt and improving our financial health through the oil and gas cycle Successful execution of FY17 Action Plan and recent tender successes are evidence to our stakeholders that we can maintain our leadership position during this prolonged downturn

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.

Bristow Value Added (BVA) Sample calculation for Q3 FY17 and Q3 FY16 Bristow Value Added = Gross Cash Flow – (Gross Operating Assets X Capital Charge) BVA = GCF – (GOA x 10.5%1) Bristow Value Added calculation for Q3 FY17 $(14.2) = $85.6 – ($3,801* x 2.625%1) Bristow Value Added calculation for Q3 FY16 $19.2 = $123.0 – ($3,956* x 2.625%1) 1) Quarterly capital charge of 2.625% is based on annual capital charge of 10.5%
