2 Strategy and 2011 Progress Joe Hete Chief Executive Officer

3 ATSG Strategy 767 freighter dry leases with the differentiated ability to provide a wide range of complementary services generating incremental returns Dry Leasing ACMI/CMI Support Services Foundation of ATSG’s economic model – all other aircraft-related services generate incremental returns • Aircraft are leased out of Cargo Aircraft Management (CAM) subsidiary • ATSG subsidiary airlines pay market rates and compete with third party companies for access to assets • Dry leases typically have minimum term of 5-7 years and require the assumption of operating risk by the customer We will crew, maintain and insure our aircraft types for incremental (CMI) or package (A+CMI) price • Three of ATSG’s subsidiaries provide ACMI services for cargo transport companies • Customer accepts fuel-price risk • Assuming market lease rates for aircraft, ACMI business is priced to generate incremental operating returns • CMI services available for customer owned aircraft – incremental return without capital investment Additional services complement ACMI and leasing, provide incremental operating returns with minimal capital requirements • Maintenance, Repair, and Overhaul (MRO) subsidiary provides full service maintenance operations to ATSG subsidiaries and third party customers • Also provide other services such as freight sorting and logistics services; facilities management and equipment sales and leasing

4 ATSG Business Model Purchase Modify Deploy Operate/Support • Focus on the Boeing 767 with expertise in sourcing and assessing assets • More than 500 potential 767 conversion candidates • Feedstock expected to increase as Boeing 787 deliveries accelerate • Purchase price must be consistent with +10% unlevered ROIC criteria, limit asset value risk • Prefer multi-aircraft purchases from operators with solid reputations for quality aircraft • Secure slots with principal 767 modification provider IAI • Maintain steady supply to conversion lines, diminishing competitive threats/access • Upgrade avionics • Loading systems provide for seamless container transfer to larger Boeing 747s & 777s • Modified aircraft receives airframe heavy maintenance via ATSG MRO subsidiary • Fundamental allocation principle: Best-available risk-adjusted ROI with balance of short and long-term commitments • Flexibility to respond to opportunities, but foundation is long-term, predictable, low-risk dry leases • Assessment includes: – financial condition of customer – growth potential of customer’s air cargo network or markets – customer concentration – opportunity to provide value-added services • Crew, maintenance and insurance (CMI) for fleet aircraft and third-party customers • Maintenance expertise • Advanced avionics upgrade capability, including navigation/radar systems, flat panel displays, etc. • Cost-competitive engineering technical services in central U.S. location • Network flight operations management for third parties

5 2011 Accomplishments Organizational Financial Operational • Began CCIA and ATI reorganization to adjust to downsizing BAX network from Sept. 1 through 4Q. • Created Global Flight Source to leverage dispatch and flight following services capability. • Adopted new tools for financial analysis, sales development, and financial performance. • Reorganized and rebranded ABX Cargo as LGSTX Distribution Services. • Established new credit facility to secure more flexible growth financial capacity through 2015 • Funded purchases of seven more aircraft, and completed modifications of seven others in $210 million capital program. • Created new ATSG Accounting Department to improve financial reporting and analysis • Continued to explore strategic and financial opportunities to increase shareholder value • Gained favorable tax treatment for continuing investments in freighter modifications • Completed wind-down of dedicated BAX air network while simultaneously accommodating related expansion of DHL-US network • Made preparations to sell or scrap most of legacy DC-8 and Boeing 727 freighters, while re-training targeted crews on 767 and 757. • Deployed 10 full freighters into our fleet, including nine 767s and one 757. • Launched modification program for 757s into combi aircraft as planned replacements for DC-8 combis • Negotiated new CBA with ATI pilots

Adjusted Pre-Tax Earnings from Continuing Operations, Adjusted EBITDA from Continuing Operations and Debt Obligations/Adjusted EBITDA Ratio are non-GAAP financial measures and should not be considered alternatives to net income or any other performance measure derived in accordance with GAAP. Adjusted Pre-Tax Earnings from Continuing Operations excludes the results from Severance & Retention Activities, unrealized gains or losses in derivative instruments, impairment charges for aircraft, goodwill & intangibles, and costs from termination of credit agreements. Adjusted EBITDA from Continuing Operations is defined as EBITDA (Pretax Earnings (loss) from Continuing Operations Before Income Taxes minus Interest Income, plus Interest Expense and plus Depreciation and Amortization) excluding results from Severance & Retention Activities, unrealized gains or losses in derivative instruments, impairment charges for aircraft, goodwill & intangibles, and costs from termination of credit agreements. Debt Obligations/Adjusted EBITDA Ratio is defined as Debt Obligations (Long-term Debt Obligations plus Current Portion of Debt Obligations at end of period) divided by Adjusted EBITDA from Continuing Operations. Management uses these adjusted financial measures in conjunction with GAAP finance measures to monitor and evaluate its performance, including as a measure of financial strength. Adjusted Pre-tax Earnings, Adjusted EBITDA and Debt Obligations/Adjusted EBITDA Ratio should not be considered in isolation or as a substitute for analysis of the Company’s results as reported under GAAP, or as alternative measures of liquidity. 2008 2009 2010 2011 ( 6,619)$ 45,358$ 63,317$ 40,860$ Im airment Charges 9 ,241 - - 27,144 Sev rance & Retenti n (816) (16,727) (3,549) - Net Deriv.
