US AIRWAYS REPORTS RECORD SECOND QUARTER PROFIT

Record pretax profit of $409 million excluding special items

Highlights of US Airways Group, Inc.’s (the Company) second quarter 2013 results:

TEMPE, Ariz., July 24, 2013 — US Airways Group, Inc. (NYSE: LCC) today reported its second quarter 2013 financial results. For the second quarter 2013, pretax profit excluding net special items was $409 million, the highest in Company history. Net profit excluding net special items was a record $324 million, or $1.58 per diluted share. Net profit excluding net special items for the second quarter 2012 was $321 million, or $1.61 per diluted share. The Company’s 2013 second quarter net profit excluding net special items was negatively impacted by a non-cash provision for income tax of $85 million. There was no provision for income tax recorded in 2012.

On a GAAP basis, the Company reported a net profit of $287 million for its second quarter 2013, or $1.40 per diluted share. This compares to a net profit of $306 million, or $1.54 per diluted share, for the same period in 2012. The Company’s 2013 second quarter net profit was negatively impacted by a non-cash provision for income tax of $67 million.

See the accompanying notes in the Financial Tables section of this press release for a reconciliation of GAAP financial information to non-GAAP financial information.

“These record financial results are thanks to the 32,000 team members of US Airways who delivered record results on multiple fronts,” said US Airways Chairman and CEO Doug Parker. “This performance provides excellent momentum as we transition into the new American Airlines. The teams are working very well together and we continue to expect to close the merger in the third quarter.”

Revenue and Cost Comparisons

Total revenues in the second quarter were a record $3.9 billion, up 2.9 percent versus the second quarter 2012 on a 3.4 percent increase in total available seat miles (ASMs). Total revenue per ASM was 16.22 cents, down 0.5 percent versus the same period last year driven by a 2.8 percent decrease in passenger yield, offset by a record quarterly load factor of 85.1 percent.

Total operating expenses in the second quarter were $3.4 billion, up 1.0 percent over the same period last year. Mainline cost per available seat mile (CASM) was 12.88 cents, down 2.0 percent on a 4.2 percent increase in mainline ASMs. Excluding special items, fuel and profit sharing, mainline CASM was 8.21 cents, down 0.4 percent versus the same period last year. Express CASM excluding special items and fuel was 14.34 cents, up 1.1 percent on a 0.3 percent decrease in ASMs.

Liquidity

As of June 30, 2013, the Company had a record $4.0 billion in total cash and investments, of which $350 million was restricted. This is up approximately $1.1 billion from the Company’s first quarter 2013 total cash and investments balance of $2.9 billion, of which $352 million was restricted.

During the second quarter, the Company raised approximately $870 million in net incremental cash through a series of financing transactions. These transactions included the refinancing of the Company’s term loan (resulting in approximately $270 million in incremental cash); the issuance of high yield bonds in an aggregate principal amount of $500 million; and a $100 million C-tranche to its 2012-2 EETC.

“We are extremely pleased with the results of our recent financing transactions,” said US Airways’ Chief Financial Officer Derek Kerr. “Our record financial results combined with our pending merger with American have enabled the Company to refinance its term loan and secure incremental liquidity at very attractive rates.”

Special Items

The Company recognized approximately $55 million of net special items before taxes in the second quarter. Operating special items totaled $24 million and were primarily related to merger costs. The Company also recognized approximately $31 million in nonoperating special items primarily related to debt extinguishment charges due to non-cash write offs of debt discount and debt issuance costs in connection with conversions of the Company’s 7.25% convertible senior notes and repayment of the Citicorp North America term loan. The net tax effect of these special items was approximately $18 million.

Merger Update

The Company and its representatives continue to work closely with their counterparts at American in merger integration planning. The Company continues to expect the transaction to close in the third quarter. Recent accomplishments include:

Reconciliation of GAAP Financial Information to Non-GAAP Financial Information

US Airways Group, Inc. (the “Company”) is providing disclosure of the reconciliation of reported non-GAAP financial measures to their comparable financial measures on a GAAP basis. The Company believes that the non-GAAP financial measures provide investors the ability to measure financial performance excluding special items and profit sharing, which is more indicative of the Company’s ongoing performance and is more comparable to measures reported by other major airlines. The Company believes that the presentation of mainline and express CASM excluding fuel is useful to investors as both the cost and availability of fuel are subject to many economic and political factors beyond the Company’s control. Management uses mainline and express CASM excluding special items, fuel and profit sharing to evaluate the Company’s operating performance.
