CEO remarks and safety review Jonathan Baliff, President and CEO

5 FY15 operational safety review 1) AAR includes commercial operations for Bristow Group and consolidated affiliates, Eastern Airways and Airnorth 2) TRIR for FY15 includes consolidated commercial operations, corporate, Bristow Academy, Eastern Airways, and Airnorth employees Total Recordable Injury Rate² (TRIR) per 200,000 man hours (cumulative) FY15 Air Accident Rate 1 (AAR) per 100,000 flight hours (fiscal year) 0 0 • Achieved one full year of global Target Zero in August 2014 and two consecutive years with zero air accidents in March 2015 • FY15 Total Recordable Injury Rate of 0.23, a 12% improvement from FY14 • NABU and WASBU were Target Zero for air and ground in FY15 • FY15 saw the successful launch of HeliOffshore with vital work ongoing for industry “Safety Through Collaboration”

6 FY15 highlights • High reliability and excellent client service led to 13.9% revenue growth to $1.7 billion in FY15 • Proactive cost and capital efficiency led to FY15 adjusted EBITDAR* of $474 million, BVA** of $100 million, and operating cash flow of $253 million • On-time, on-budget launch of $2.5 billion UK SAR contract • Expanded our integrated point-to-point logistics service offering to Australia through the acquisition of Airnorth • Increased quarterly dividend by 6% to $0.34 per share; more than doubled since its initiation in 2011 at $0.15/share *Adjusted EBITDAR amounts exclude gains and losses on dispositions of assets and any special items during the period. See reconciliation of these items to GAAP measures in the appendix hereto and in our earnings release for the quarter and fiscal year ended March 31, 2015. **Bristow Value Added (BVA) is calculated by taking gross cash flow less the product of gross operating assets times a capital charge of 10.5%. Example calculation can be found in the appendix hereto. .

7 Bristow market perspectives Overall market perspective • Bristow continues to believe this is not just a supply-oriented decline, but is driven by weaker than expected demand for oil • Bristow believes in a U-shaped recovery that will continue for 18-24 months from today • Delayed recovery and oil price volatility may defer final investment decisions on key unsanctioned offshore projects • Although production-oriented services (like aviation) are doing better than most in OFS, available aircraft capacity continues to increase • Our clients continue to be aggressive in lowering their costs to maximize returns on their offshore portfolios • The severity of this downturn is not uniform among regions, with geographies like the North Sea more acutely impacted Offshore aviation market perspective

19 LACE and LACE rate FY16 average LACE guidance range initiated at 170-180 and average LACE rate guidance range initiated at $8.00 - $9.00 million *See appendix hereto for more information on LACE and LACE rate. Consolidated commercial aircraft, LACE and LACE rate exclude Bristow Academy, affiliate aircraft, fixed wing aircraft, aircraft held for sale, aircraft construction in progress and reimbursable revenue.

20 Bristow Value Added (BVA) drives improving Gross Cash Flow (GCF) performance • Q4 FY15 absolute BVA is positive $29.3M, a $0.6M or 2% increase from Q4 FY14 • Year-over-year change in BVA is driven by: Revenue growth Margin improvement Capital efficiency efforts • EBU and NABU generated key improvements year-over-year Note: 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 the appendix for additional details.

21 Our progress on BVA yields stronger operating cash flow for growth, dividends and share repurchases Net cash provided by operating activities 1 Total liquidity 2 1) See 10-K for more information on cash flow provided by operating activities. 2) At period end 261 402 415 530 370

22 FY16 guidance initiated • FY16 adjusted EPS guidance range is initiated at $3.90 - $4.40, excluding special items and aircraft sales. FY16 guidance includes: *Assuming FY16 revenue earned in same regions and same mix as in FY15. Average LACE (Large AirCraft Equivalent) ~170-180 Interest expense ~ $35 - $45M Average LACE Rate ~ $8.00 - $9.00M Rent expense (aircraft only) ~$185 - $195M G & A expense (all inclusive) ~ $220 - $240M Tax rate* ~ 21 - 24% Depreciation expense ~ $125 - $135M Adj. EPS guidance $3.90 - $4.40 FY16 guidance as of March 31, 2015

23 FY16 adjusted EPS guidance bridge from FY15 • FY15 results adjusted for foreign exchange effect of $0.88 bridges to reported adjusted EPS of $3.77 (~$4.65 in total) • FY16 expected net decline in oil and gas with addition of UK SAR yields an approximate $0.50 adjusted EPS decrease Bristow estimates 5% - 10% expected revenue losses in oil and gas, partially offset by $75 - $95 million of expected cost savings in FY16 UK SAR and other new business expected to add incremental adjusted EPS to FY16 • Despite the downturn, Bristow expects adjusted EBITDAR and EPS growth in FY17

24 Bristow remains well positioned for the future • Safety is and will remain our number one priority, as we build on two consecutive years of air Target Zero and continue to proactively engage with the industry through HeliOffshore • We continue to differentiate ourselves through first class efficiency and combined services, making us an indispensable partner to our clients • The offshore aviation market will remain challenging as project sanctioning is delayed and helicopter capacity increases in FY16 • That being said, we expect improved FY16 BVA and adjusted EBITDAR due to UK SAR with cost and capital efficiency in response to this downturn • We have a positive outlook for FY17, as we begin to see the full benefit from UK SAR contracts and generate more cash given our strong balance sheet and modern fleet, which is primarily owned versus leased
