Air Transport Services : ATSG'S RESULTS REFLECT GROWING RETURNS FROM FLEET INVESTMENTS

Second-Quarter Adjusted EBITDA from Continuing Operations up 13 Percent to $51 Million

WILMINGTON, OH, August 5, 2015 - Air Transport Services Group, Inc. (Nasdaq: ATSG), the leading provider of medium wide-body freighter aircraft leasing, air cargo transportation and related services, today reported consolidated financial results for the quarter ended June 30, 2015.

For the second quarter of 2015, compared with the second quarter of 2014 except as noted:

• Pre-tax earnings from continuing operations increased 17 percent to $17.2 million, including a 35 percent increase in Cargo Aircraft Management's pre-tax earnings, driven by eight additional freighters leased to external customers.

• Net earnings from continuing operations increased 14 percent to $10.6 million, or 16 cents per diluted share. Operating loss carryforwards for U.S. federal income tax purposes offset much of the company's federal tax liabilities. ATSG does not expect to pay significant federal income taxes until

2017 at the earliest.

• Consolidated revenues were approximately flat at $148.4 million. Excluding revenues from reimbursed expenses, revenues increased 3 percent. Revenues from cargo aircraft leasing were up 12 percent.

• Adjusted EBITDA (Earnings Before Interest, Taxes, Depreciation and Amortization) increased 13 percent to $51.2 million, and increased 16 percent to $97.7 million year to date. Adjusted EBITDA is a non-GAAP financial measure, defined and reconciled to comparable GAAP results in a table at the

end of this release.

Joe Hete, President and Chief Executive Officer of ATSG, said, 'Our record first-half Adjusted EBITDA stems from a combination of improved airline operations and continued growth in aircraft leasing, leading us closer to full deployment of our available aircraft and reflects strong appetites from current and new customers for more of our highly efficient Boeing 767 freighters and related services.'

The second quarter marked the commencement of a new four-year commercial agreement governing air network services that ATSG provides to DHL. It began with fifteen dry leases for Boeing 767 freighters dedicated to DHL through March 2019, currently operating in its U.S. network. DHL added a sixteenth dry lease, a 767-300 freighter delivered in June, and we expect to place two additional 767-300s, both under eight-year lease terms, during the fourth quarter of 2015. Accordingly, ATSG has purchased two more passenger-configured 767-300s for freighter conversion to meet DHL's requirement.

Segment Results

Cargo Aircraft Management (CAM)

Significant Developments:

• The increase in CAM's second-quarter revenue was driven by eight additional dry-leased 767 freighters to external customers, which increased to 29 as of June 30, 2015 from 21 at June 30, 2014, and from 24 at March 31, 2015.

• The 35 percent increase in pre-tax earnings for the quarter reflects the increased number of dry-leased aircraft, along with increased depreciation costs.

• At June 30, 2015, CAM owned 54 Boeing cargo aircraft in serviceable condition, three more than a year ago. CAM has purchased two additional 767-300 aircraft, one in June and one in July, which will be converted to freighters and dry-leased during the fourth quarter.

ACMI Services

Significant Developments:

• Quarterly results for the segment improved on a year-over-year and sequential quarter basis. Results benefited from a full quarter of 767 ACMI service for Raya Airways of Malaysia, which began in February. West Coast operations for Aloha Airlines, which began in the third quarter of 2014, also contributed to improved year-over-year results.

• The quarter also benefited from fewer heavy maintenance checks for our Boeing 767-200 freighters than a year ago, and from net insurance recoveries of just over $2 million. During the third quarter of

2015, the cost of unreimbursed expensed heavy maintenance checks for 767-200s is expected to be higher than in the second quarter.

• Our airlines leased from CAM and operated on an ACMI basis fifteen Boeing 767 freighters as of June

30, 2015, five fewer than at March 31, 2015 and three fewer than on June 30, 2014, reflecting increasing allocations of our fleet to dry lease opportunities based upon strong customer demand.

Other Activities

Significant Developments:

• External customer revenues from all other activities in the second quarter were $20 million, down slightly compared to second quarter 2014. The earnings comparison reflects timing variances in revenue recognition for maintenance services for outside customers, offset in part by increased revenues for management of sorting centers for the USPS.

Outlook

As a result of strong first-half performance and a positive outlook for the rest of 2015, ATSG now projects that its baseline Adjusted EBITDA from Continuing Operations for 2015 will be in a range of $190-195 million.

Hete noted that, 'In 2015, we are achieving growing returns from the significant investments we have made in our fleet and operations, as customers are stepping up to make major commitments to our assets and operating capabilities. For example, Delta Air Lines recently selected AMES, our maintenance MRO, to provide airframe maintenance services for its fleet of more than eighty Boeing 717 aircraft at AMES's expanded hangar facilities in Wilmington. This new five-year arrangement is expected to be finalized and start in the fourth quarter this year. We are pleased that Delta, our long-term engine maintenance partner, has entrusted us with airframe maintenance support for this portion of their fleet.

'We also have other multi-year commitments in the works with customers that we expect to announce and launch later this year, in addition to the two 767-300s we plan to deliver to DHL in the fourth quarter. At the same time, we will also incur some transition effects in the third quarter as we prepare our aircraft for long-duration dry-lease arrangements. But with continued strong industry demand and continued share repurchases, our shareholders can expect even greater long-term returns under our differentiated business model,' Hete said.

For all periods presented above, airline service reven ues include compensation for maintenance provided by the airlines on aircraft operated for DHL. Reimbursables revenues declined for the three and six month periods ending June 30, 2015 compared to the corresponding periods of 2014 due to lower fuel prices and the return of four DHL-owned Boeing 767-200 aircraft.
