Notes to Condensed Consolidated Financial Statements

August 31, 2012

(Unaudited)

(Dollars in millions, except per share amounts)

Note 1 — Basis of Presentation

AAR CORP. and its subsidiaries are referred to herein collectively as “AAR,” “Company,” “we,” “us,” and “our,” unless the context indicates otherwise. The accompanying condensed consolidated financial statements include the accounts of AAR and its subsidiaries after elimination of intercompany accounts and transactions.

We have prepared these statements without audit, pursuant to the rules and regulations of the United States Securities and Exchange Commission (“SEC”). The condensed consolidated balance sheet as of May 31, 2012 has been derived from audited financial statements. To prepare the financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”), management has made a number of estimates and assumptions relating to the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities. Actual results could differ from those estimates. Certain information and note disclosures, normally included in comprehensive financial statements prepared in accordance with GAAP, have been condensed or omitted pursuant to such rules and regulations of the SEC. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in our latest annual report on Form 10-K.

In the opinion of management, the condensed consolidated financial statements reflect all adjustments (which consist only of normal recurring adjustments) necessary to present fairly the condensed consolidated financial position of AAR CORP. and its subsidiaries as of August 31, 2012, the condensed consolidated statements of income, the condensed consolidated statements of comprehensive income, and its cash flows for the three-month periods ended August 31, 2012 and 2011 and the condensed consolidated statement of changes in equity for the three-month period ended August 31, 2012. The results of operations for such interim periods are not necessarily indicative of the results for the full year.

Note 2 — Revenue Recognition

Sales and related cost of sales for product sales are recognized upon shipment of the product to the customer. Our standard terms and conditions provide that title passes to the customer when the product is shipped to the customer. Sales of certain defense products are recognized upon customer acceptance, which includes transfer of title. Under the majority of our expeditionary airlift services contracts, we are paid and record as revenue a fixed daily amount per aircraft for each day an aircraft is available to perform airlift services. In addition, we are paid and record as revenue an amount which is based on number of hours flown. Sales from services and the related cost of services are generally recognized when customer-owned material is shipped back to the customer. We have adopted this accounting policy because at the time the customer-owned material is shipped back to the customer, all services related to that material are complete as our service agreements generally do not require us to provide services at customer sites. Furthermore, serviced units are typically shipped to the customer immediately upon completion of the related services. Sales and related cost of sales for certain long-term manufacturing contracts and certain large airframe maintenance contracts and performance-based logistics programs are recognized by the percentage of completion method, either based on the relationship of costs incurred to date to estimated total costs or the units of delivery method. Lease revenues are recognized as earned. Income from monthly or quarterly rental payments is recorded in the pertinent period according to the lease agreement. However, for leases that provide variable rents, we recognize lease income on a straight-line basis. In addition to a monthly lease rate, some engine leases require an additional rental amount based on the number of hours the engine is used in a particular month. Lease income associated with these contingent rentals is recorded in the period in which actual usage is reported to us by the lessee, which is normally the month following the actual usage.

Certain supply chain management programs we provide our customers contain multiple elements or deliverables, such as program and warehouse management, parts distribution and maintenance and repair services. We recognize revenue for each element or deliverable that can be identified as a separate unit of accounting at the time of delivery based upon the relative fair value of the products and services.

Included in accounts receivable as of August 31, 2012 and May 31, 2012, are $30.7 million and $36.2 million, respectively, of unbilled accounts receivable related to a defense supply chain support agreement. These

(Unaudited)

(Dollars in millions, except per share amounts)

unbilled accounts receivable relate to costs we have incurred on parts that were requested and accepted by our customer to support the program. These costs have not been billed by us because the customer has not issued the final paperwork necessary to allow for billing.

In addition to the unbilled accounts receivable, included in Other on the condensed consolidated balance sheet as of August 31, 2012 and May 31, 2012, are $28.9 million and $27.9 million, respectively, of costs in excess of amounts billed for the same defense supply chain support agreement. We expect to recover costs in excess of amounts billed through future billings over the life of the program.

Note 3 — Accounting for Stock-Based Compensation

Stock Options

In July 2012, as part of our annual long-term stock incentive compensation, we granted 958,180 stock options to eligible employees at an exercise price of $12.90 and weighted average fair value of $4.6 million. The fair value of stock options is estimated on the date of grant using the Black-Scholes option pricing model with the following assumptions:

|  | Three Months Ended |
|  | August 31, |
|  | 2012 |  | 2011 |
Risk-free interest rate |  | 0.6 | % | 1.5 | %
Expected volatility of common stock |  | 51 | % | 46 | %
Dividend yield |  | 2.3 | % | 1.0 | %
Expected option term in years |  | 5.4 |  | 5.7 |

The total intrinsic value of stock options exercised during the three-month periods ended August 31, 2012 and 2011 was zero and $3.3 million, respectively. Expense charged to operations for stock options during the three-month periods ended August 31, 2012 and 2011 was $0.7 and $1.1 million, respectively.

Restricted Stock

In July 2012, as part of our annual long-term stock incentive compensation, we granted 53,280 shares of performance-based restricted stock and 65,780 restricted shares to eligible employees. The grant date fair value per share was $12.90. We also granted 45,000 restricted shares to members of the Board of Director with a grant date fair value per share of $11.56. Expense charged to operations for restricted stock during the three-month periods ended August 31, 2012 and 2011 was $2.2 million and $1.5 million, respectively.

Note 4 — Inventory

The summary of inventories is as follows:

|  | August 31, |  | May 31, |
|  | 2012 |  | 2012 |
Raw materials and parts |  | $ | 97.0 |  | $ | 101.3 |

At August 31, 2012, the face value of our debt was $806.3 million and the estimated fair value was approximately $799.1 million.

The fair value amounts of our long-term debt securities are estimated using significant other observable inputs including quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active. This debt is classified as Level 2 in the fair value hierarchy.

We are subject to a number of covenants under our financing arrangements, including restrictions which relate to the payment of cash dividends, maintenance of minimum net working capital and tangible net worth levels, fixed charge coverage ratio, sales of assets, additional financing, purchase of our shares and other matters. We are in compliance with all financial covenants under our financing arrangements.

As of August 31, 2012 and May 31, 2012, the long-term debt and equity component (recorded in capital surplus, net of income tax benefit) consisted of the following:

|  | August 31, |  | May 31, |
|  | 2012 |  | 2012 |
Long-term debt: |  |  |  |  |
Principal amount |  | $ | 216.3 |  | $ | 229.3 |
Unamortized discount |  | (15.8 | ) | (19.8 | )
Net carrying amount |  | $ | 200.5 |  | $ | 209.5 |
Equity component, net of tax |  | $ | 74.8 |  | $ | 74.8 |

The discount on the liability component of long-term debt is being amortized using the effective interest method based on an effective rate of 8.48% for our 1.75% convertible notes; 6.82% for our 1.625% convertible notes and 7.41% for our 2.25% convertible notes. For our 1.75% convertible notes, the discount is being amortized through February 1, 2013, which is the first put date for those notes. For our 1.625% and 2.25% convertible notes, the discount is being amortized through their respective maturity dates of March 1, 2014 and March 1, 2016.

As of August 31, 2012 and 2011, for each of our convertible note issuances, the “if converted” value does not exceed its principal amount.

The interest expense associated with the convertible notes was as follows:

|  | Three Months Ended |

Note 7 — Derivative Instruments and Hedging Activities

We are exposed to interest rate risk associated with fluctuations in interest rates on our variable rate debt. During the first quarter of fiscal 2012, we entered into two derivative financial instruments in order to manage our variable interest rate exposure over a medium- to long-term period. We use a floating-to-fixed interest rate swap to hedge interest on $50 million of notional principal balance under our revolving credit agreement. We also use an interest rate cap agreement on $50 million of notional principal interest under our revolving credit agreement.

We do not hold or issue derivative instruments for trading purposes and are not a party to any instruments with leverage or prepayment features. In connection with derivative financial instruments, there exists the risk of the possible inability of counterparties to meet the terms of their contracts. We mitigate this risk by performing financial reviews before the contract is entered into, as well as on-going periodic evaluations. We do not expect any significant losses from counterparty defaults.

We classify the derivatives as assets or liabilities on the balance sheet. Accounting for the change in fair value of the derivatives is a function of whether the instrument qualifies for, and has been designated as, a hedging relationship, and the type of hedging relationship. As of August 31, 2012, all of our derivative instruments were classified as cash flow hedges. The fair value of our interest rate swap and our interest cap agreements represents the difference in the present values of cash flows calculated at the contracted interest rates and at current market interest rates at the end of the reporting period.

We record the fair value of assets and liabilities in accordance with the hierarchy established by the authoritative guidance for fair value measurements. The fair value of our interest rate derivatives are classified as Level 2, which refers to fair values estimated using significant other observable inputs including quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active. The following table summarizes the classification and fair values of our interest rate derivative instruments reported in the condensed consolidated balance sheet as of August 31, 2012.

|  |  |  | Derivative |  | Derivative |
Derivatives designated |  |  |  | Assets |  | Liabilities |
as hedging instruments |  | Balance Sheet Classification |  | August 31, 2012 |  | August 31, 2012 |
Interest rate cap |  | Long-term assets |  | $ | 0.2 |  | $ | — |
Interest rate swap |  | Long-term liabilities |  | — |  | (5.0 | )

The following table summarizes the classification and fair values of our interest rate derivative instruments reported in the condensed consolidated balance sheet as of May 31, 2012.

|  |  |  | Derivative |  | Derivative |
Derivatives designated |  |  |  | Assets |  | Liabilities |
as hedging instruments |  | Balance Sheet Classification |  | May 31, 2012 |  | May 31, 2012 |
Interest rate cap |  | Long-term assets |  | $ | 0.2 |  | $ | — |
Interest rate swap |  | Long-term liabilities |  | — |  | (4.5 | )

We include gains and losses on the derivative instruments in other comprehensive income. We recognize the gains and losses on our derivative instruments as an adjustment to interest expense in the period the hedged interest payment affects earnings. The impact of the interest rate swap and interest cap agreement for the three-month periods ended August 31, 2012 and 2011 was an unrealized loss of $0.4 million and $2.5 million, respectively, recorded in accumulated other comprehensive income (loss). We expect minimal gain or loss to be reclassified into earnings within the next 12 months.

Note 8 — Earnings per Share

The computation of basic earnings per share is based on the weighted average number of common shares outstanding during each period. The computation of diluted earnings per share is based on the weighted average

(Dollars in millions, except per share amounts)

number of common shares outstanding during the period plus, when their effect is dilutive, incremental shares consisting of shares subject to stock options, shares issuable upon vesting of restricted stock awards and shares to be issued upon conversion of convertible debt.

We use the “if-converted” method in calculating the diluted earnings per share effect of the assumed conversion of our contingently convertible debt issued in fiscal 2006 because the principal for that issuance can be settled in stock, cash or a combination thereof. Under the “if converted” method, the after-tax effect of interest expense related to the convertible securities is added back to net income, and the convertible debt is assumed to have been converted into common shares at the beginning of the period.

In accordance with ASC 260-10-45, Share-Based Payment Arrangements and Participating Securities and the Two-Class Method, our unvested restricted stock awards are deemed participating securities since these shares are entitled to participate in dividends declared on common shares. During periods of net income, the calculation of earnings per share for common stock exclude income attributable to unvested restricted stock awards from the numerator and exclude the dilutive impact of those shares from the denominator. During periods of net loss, no effect is given to the participating securities because they do not share in the losses of the Company.

The following table provides a reconciliation of the computations of basic and diluted earnings per share information for the three-month periods ended August 31, 2012 and 2011.

|  | Three Months Ended |
|  | August 31, |
|  | 2012 |  | 2011 |
Basic EPS: |  |  |  |  |

Weighted average common shares outstanding — diluted |  | 41.7 |  | 43.3 |
Earnings per share — diluted |  | $ | 0.45 |  | $ | 0.41 |

At August 31, 2012 and 2011, respectively, stock options to purchase 1,489,672 shares and 210,000 shares of common stock were outstanding, but were not included in the computation of diluted earnings per share because the exercise price of each of these options was greater than the average market price of the common shares during the interim periods then ended.

Note 9 — Acquisitions

On December 2, 2011, we acquired Telair International GmbH (“Telair”) and Nordisk Aviation Products, AS (“Nordisk). Telair is a leader in the design, manufacture and support of cargo loading systems for wide-body and narrow-body aircraft with established positions on the world’s most popular current and next-generation passenger and freighter aircraft. Telair operates from facilities in Germany, Sweden and Singapore. Nordisk designs and manufactures heavy duty pallets and lightweight cargo containers for commercial airlines from facilities in Norway and China. The purchase price of the acquisition was $280 million paid at closing, plus or minus a working capital adjustment. During the fourth quarter of fiscal 2012, the working capital adjustment was finalized, which increased the purchase price to $296.5 million. The $16.5 million was paid in the first quarter of fiscal 2013. The businesses operate as part of our Structures and Systems segment.

On October 11, 2011, we acquired Airinmar Holdings Limited (“Airinmar”), a sophisticated repair, outsourcing and warranty claim manager. Airinmar operates as part of our Aviation Supply Chain segment. Total consideration is estimated to be $43.5 million, which included $23.2 million cash paid at closing, and a potential earn-out payment of $20.3 million. The potential earn-out payment is based upon Airinmar achieving certain EBITDA (earnings before interest, taxes, depreciation and amortization) levels over a two-year period, as well as retaining certain key customers. In accordance with accounting principles generally accepted in the United States of America, a liability of $20.3 million was recognized as an estimate of the acquisition date fair value of the earn-out and was included in Other non-current liabilities on our consolidated balance sheet as of February 29, 2012. During the fourth quarter of 2012, this estimate was reduced by $3.4 million and this change in the fair value of the earn-out was recognized in earnings.

During the current period, we completed the final purchase price allocation for Airinmar and the results are as follows:

Cash |  | $ | 3.7 |
Accounts receivable |  | 8.0 |
Prepaid expenses |  | 0.9 |
Property, plant and equipment |  | 0.6 |
Deferred tax assets |  | 5.3 |
Goodwill and identified intangibles |  | 42.4 |
Accounts payable |  | (6.7 | )
Deferred tax liabilities |  | (5.3 | )
Accrued liabilities |  | (5.4 | )

For Telair and Nordisk, we are continuing the review of our fair value estimate of assets acquired and liabilities assumed during the measurement period, which will conclude as soon as we receive the information we are seeking about facts and circumstances that existed as of the acquisition date, or learn that more information is not available. This measurement period will not exceed one year from the acquisition date. At the effective date of the acquisition, the assets acquired and liabilities assumed are generally required to be measured at fair value.

Our fair value estimate of assets acquired and liabilities assumed is pending completion of several elements, including the finalization of an independent appraisal and valuations of fair value of the assets acquired and liabilities assumed and final review by our management. The primary areas that are not yet finalized relate to the fair value of property and equipment, intangible assets and income and non-income related taxes. Accordingly, there could be material adjustments to our consolidated financial statements, including changes in our depreciation and amortization expense related to the valuation of property and equipment and intangible assets acquired and their respective useful lives among other adjustments.

(Dollars in millions, except per share amounts)

The final determination of the assets acquired and liabilities assumed will be based on the established fair value of the assets acquired and the liabilities assumed as of the acquisition date. The excess of the purchase price over the fair value of net assets acquired is allocated to goodwill. The final determination of the purchase price, fair values and resulting goodwill may differ significantly from what is reflected in the consolidated financial statements.

The preliminary purchase price allocation for Telair and Nordisk is as follows:

Cash |  | $ | 1.5 |
Accounts receivable |  | 47.1 |
Inventories |  | 54.5 |
Prepaid expenses |  | 4.1 |
Property, plant and equipment |  | 17.0 |
Deferred tax assets |  | 34.3 |
Goodwill and identified intangibles |  | 223.9 |
Notes payable |  | (1.6 | )
Accounts payable |  | (14.7 | )
Deferred tax liabilities |  | (34.3 | )
Accrued liabilities |  | (27.5 | )
Other long-term liabilities |  | (7.8 | )

Note 10 — Program Development Costs

In June 2005, we announced that our Cargo Systems business was selected to provide cargo handling systems for the new Airbus A400M Military Transport Aircraft (“A400M”). Our portion of the revenue from this program is expected to exceed $300 million through fiscal 2021, based on sales projections of the A400M. As of August 31, 2012 and May 31, 2012, we have capitalized, net of reimbursements, $101.7 million and $91.9 million, respectively, of costs associated with the engineering and development of the cargo system. Sales and related cost of sales will be recognized on the units of delivery method. In determining the recoverability of the capitalized program development costs, we have utilized certain judgments and estimates concerning expected revenues and the cost to manufacture the A400M cargo system. Differences between actual results and the assumptions utilized by us may result in us not fully recovering the value of the program development costs, which would unfavorably impact our financial condition and results of operations.

Note 11 —Aircraft Portfolio

Within our Aviation Supply Chain segment, we own commercial aircraft with joint venture partners as well as aircraft that are wholly-owned. These aircraft are available for lease or sale to commercial air carriers.

Aircraft Owned through Joint Ventures

As of August 31, 2012 and May 31, 2012, we had ownership interests in 18 aircraft with joint venture partners. As of August 31, 2012 and May 31, 2012, our equity investment in aircraft owned with joint venture partners was approximately $41.3 million and is included in Investment in joint ventures on the Condensed Consolidated Balance Sheet. Our aircraft joint ventures represent investments in limited liability companies that are accounted for under the equity method of accounting. Our membership interest in each of these limited liability companies is 50% and the primary business of these companies is the acquisition, ownership, lease and disposition of certain commercial aircraft. Aircraft are purchased with cash contributions by the members of the companies and debt financing provided to the limited liability companies on a limited recourse basis. Under the terms of servicing agreements with certain of the limited liability companies, we provide administrative services and technical advisory services, including aircraft evaluations, oversight and logistical support of the maintenance process and records management. We also provide remarketing services with respect to the divestiture of aircraft by the limited liability companies. For the three-month periods ended August 31, 2012 and 2011, we were paid $0.2 million and $0.2

Note 12 — Business Segment Information

We report our activities in four business segments: Aviation Supply Chain; Government and Defense Services; Maintenance, Repair and Overhaul; and Structures and Systems.

Sales in the Aviation Supply Chain segment are derived from the sale and lease of a wide variety of new, overhauled and repaired engine and airframe parts and components principally to the commercial aviation market. We also offer customized inventory supply chain management programs and aircraft component repair management services. Sales also include the sale and lease of commercial aircraft and jet engines and technical and advisory services. Cost of sales consists principally of the cost of product, direct labor, overhead (primarily indirect labor, facility cost and insurance) and the cost of lease revenue (primarily depreciation and insurance).

Sales in the Government and Defense Services segment are derived from the sale of new and overhauled engine and airframe parts and components, customized performance based logistics programs, expeditionary airlift services, aircraft modifications and engineering, design, and integration services to our government and defense customers. Cost of sales consists principally of the cost of the product (primarily aircraft and engine parts), direct labor, overhead and aircraft maintenance costs.

Sales in the Maintenance, Repair and Overhaul segment are principally derived from aircraft maintenance and modifications, engineering services, painting, and the repair, overhaul and exchange of landing gear. Cost of sales consists principally of the cost of product (primarily replacement aircraft parts), direct labor and overhead.

Sales in the Structures and Systems segment are derived from the engineering, design and manufacture of containers, pallets and shelters used to support the U.S. military’s requirements for a mobile and agile force, heavy-duty pallets and lightweight cargo containers for the commercial market, complex machined and fabricated parts, components and sub-systems for various aerospace and defense programs and other applications, in-plane cargo

loading and handling systems for commercial and military applications and composite products for aviation and industrial use. Cost of sales consists principally of the cost of product, direct labor and overhead.

The accounting policies for the segments are the same as those described in Note 1 of Notes to Consolidated Financial Statements included in our annual report on Form 10-K for the year ended May 31, 2012. Our chief operating decision making officer (Chief Executive Officer) evaluates performance based on the reportable segments and utilizes gross profit as a primary profitability measure. The expenses and assets related to corporate activities are not allocated to the segments. Our reportable segments are aligned principally around differences in products and services.

Gross profit is calculated by subtracting cost of sales from sales. Selected financial information for each segment is as follows:

General Overview

We report our activities in four business segments: Aviation Supply Chain; Government and Defense Services; Maintenance, Repair and Overhaul; and Structures and Systems. The table below sets forth consolidated sales for our four business segments for the three-month periods ended August 31, 2012 and 2011.

|  | Three Months Ended |
|  | August 31, |
|  | 2012 |  | 2011 |
Sales: |  |  |  |  |
Aviation Supply Chain |  | $ | 148.7 |  | $ | 161.1 |
Government and Defense Services |  | 150.6 |  | 150.0 |
Maintenance, Repair and Overhaul |  | 105.5 |  | 93.2 |
Structures and Systems |  | 145.7 |  | 81.2 |
|  | $ | 550.5 |  | $ | 485.5 |

During the first quarter of fiscal 2013, sales to commercial customers increased 24.7% compared to the prior year and represented 57.2% of consolidated sales. Commercial sales growth during the first quarter of fiscal 2013 was driven by strong organic growth in the Aviation Supply Chain and Maintenance, Repair and Overhaul business segments and by the inclusion of sales at Telair International GmbH (“Telair”) and Nordisk Aviation Products, AS (“Nordisk”). The prior year included approximately $33.3 million in aircraft sales.

During the first quarter of fiscal 2013, sales to global government and defense customers increased 1.1% compared to the prior year and for the three months ended August 31, 2012 represented 42.8% of consolidated sales.

Defense funding is currently facing pressure due to U.S. budget deficit challenges. Congress has enacted the Budget Control Act of 2011 (“BCA”) which reduces defense spending by a minimum of $487 billion over a ten-year period starting in government fiscal year 2012. Under the BCA, an automatic sequestration process was triggered when the Joint Select Committee on Deficit Reduction, a committee of twelve members of Congress, failed to agree on a deficit reduction plan for the U.S. federal budget. The sequestration is scheduled to commence on January 2, 2013, absent legislative or other remedial action. Of the $1.2 trillion in reduced spending required by sequestration over the ten-year period beginning in government fiscal 2013, approximately $50 billion per year would be borne by the Department of Defense. Whether or not sequestration goes into effect, we expect the defense budget will be reduced. Although there may be additional opportunities for those business units with our Supply Chain and Maintenance, Repair and Overhaul segments that support the Department of Defense, as a result of defense spending reductions, we expect our businesses that support the Department of Defense within our Structures and Systems segment will be adversely affected.

Based on results of the first quarter and our current view, we are updating our fiscal year 2013 earnings per share guidance to a range of $1.60 to $1.70 from our previous guidance of $1.55 to $1.65.

Results of Operations

Three-Month Period Ended August 31, 2012

Consolidated sales for the first quarter ended August 31, 2012 increased $65.0 million or 13.4% compared to the prior year period. Sales to commercial customers increased 24.7% compared to the prior year and included strong organic growth in our Aviation Supply Chain and Maintenance, Repair and Overhaul segments, as well as sales from the newly acquired businesses, Telair and Nordisk. Sales to government and defense customers increased 1.1% compared to the prior year.

In the Aviation Supply Chain segment, sales decreased $12.4 million or 7.7% compared to the prior year. The prior year included approximately $33.3 million in aircraft sales; there were no aircraft sales for the first quarter of this fiscal year. The current year includes additions for the attainment of a new repair contract and Airinmar Holdings Limited (“Airinmar”) sales of $10.1 million. Gross profit in the Aviation Supply Chain segment decreased $2.5 million or 9.5%, and the gross profit margin percentage decreased to 15.9% from 16.3% in the prior year primarily due to the mix of products sold.

In the Government and Defense Services segment, sales remained flat compared to the prior year. Gross profit decreased $1.5 million or 5.5% and the gross profit margin percentage declined to 17.2% from 18.3% in the prior year. The decline in gross profit was due to lower margins on certain programs in the defense logistics business.

In the Maintenance, Repair and Overhaul segment, sales increased $12.3 million or 13.2% versus the prior year due to continued growth and share gains at our airframe maintenance centers, partially offset by lower sales at our landing gear business. Gross profit increased $2.8 million or 27.5%, and the gross profit margin percentage increased to 12.3% from 10.9% due to operational efficiencies and increased billable hours at our airframe maintenance centers.

In the Structures and Systems segment, sales increased $64.5 million or 79.4% compared to the prior year due to the inclusion of sales from Telair and Nordisk, which contributed $56.8 million of revenue during the quarter and the benefit of higher sales in our mobility business. Gross profit in the Structures and Systems segment increased $15.8 million or 132.8% and the gross profit margin percentage increased to 19.0% from 14.7% in the prior year. The increase in the gross profit margin percentage was primarily due to improved product mix resulting from acquisitions.

Selling, general and administrative expenses increased $10.2 million or 23.7% due to the inclusion of the three acquired companies and higher amortization of intangible assets. Operating income increased $5.6 million or 17.1% compared with the prior year primarily due to contributions from the acquired companies and other factors noted above. Net interest expense increased $2.8 million or 37.8% compared to the prior year primarily due to an increase in outstanding borrowings for the purchase of Telair and Nordisk. Our effective income tax rate was approximately 34.5% for both fiscal year first quarters.

Net income attributable to AAR was $18.2 million compared to $16.6 million in the prior year due to the factors discussed above.

Historically, we have funded our operating activities and met our commitments through the generation of cash from operations, augmented by the periodic issuance of common stock and debt in the public and private markets. In addition to these cash sources, our current capital resources include an unsecured credit facility, as well as a separate secured credit facility. We continually evaluate various financing arrangements, including the issuance of common stock and/or debt, which would allow us to improve our liquidity position and finance future growth on commercially reasonable terms. Our continuing ability to borrow from our lenders and issue debt and equity securities to the public and private markets in the future may be negatively affected by a number of factors, including the overall health of the credit markets, general economic conditions, airline industry conditions, geo-political events, and our operating performance. Our ability to generate cash from operations is influenced primarily by our operating performance and changes in working capital. Under our universal shelf registration statement filed with the Securities and Exchange Commission that be became effective on May 4, 2012, we registered an indeterminate number of principal amount of shares of common stock, shares of preferred stock, debt securities, warrants, stock purchase contracts and stock purchase units which may be sold from time to time, subject to market conditions.

At August 31, 2012, our liquidity and capital resources included cash of $67.7 million and working capital of $617.0 million. We have an agreement with various financial institutions, as lenders and Bank of America, N.A., as administrative agent for the lenders (as amended, the “Credit Agreement”) providing for an unsecured revolving credit facility of $580.0 million that we can draw upon for general corporate purposes. Under certain circumstances, we may request an increase to the revolving commitment by an aggregate amount of up to $100.0 million, not to exceed $680.0 million in total. The Credit Agreement expires on April 12, 2016. Borrowings under the Credit Agreement bear interest at the offered Eurodollar Rate (defined as the British Bankers Association LIBOR Rate) plus 125 to 225 basis points based on certain financial measurements if a Eurodollar Rate loan, or at the offered fluctuating Base Rate plus 25 to 125 basis points based on certain financial measurements if a Base Rate loan.

Borrowings outstanding under the Credit Agreement at August 31, 2012 were $300.0 million, and there was approximately $25.7 million of outstanding letter of credit which reduced the availability of this facility to $254.3 million. There are no other terms or covenants limiting the availability of this facility. We also have $4.4 million available under a foreign line of credit.

In addition to our unsecured Credit Agreement, we have a $65.0 million secured revolving credit facility with The Huntington National Bank (the “Huntington Loan Agreement”). Borrowings under the Huntington Loan Agreement are secured by aircraft and related engines and components owned by us. The Huntington Loan Agreement expires on April 23, 2015. Borrowings bear interest at LIBOR plus 325 basis points. As of August 31, 2012, $31.2 million was outstanding under this agreement resulting in $33.8 million remaining available. There are no other terms or covenants limiting the availability of this facility.

We are in compliance with all financial covenants under each of our financing arrangements.

During the three-month period ended August 31, 2012, our cash flow from operations was $33.2 million primarily as a result of net income attributable to AAR and noncontrolling interest and aggregate depreciation and amortization of $50.3 million and the reduction in accounts and notes receivable. These positive impacts were partially offset by a decrease in accounts and trade notes payable.

During the three-month period ended August 31, 2012, our investing activities used $16.9 million of cash principally as a result of our final payment for the acquisitions of Telair and Nordisk.

During the three-month period ended August 31, 2012, our financing activities used $17.0 million of cash primarily due to a net reduction in borrowings, the repurchase of common stock under our share repurchase program and payment of dividends.

Critical Accounting Policies and Significant Estimates

We make a number of significant estimates, assumptions and judgments in the preparation of our financial statements. See Management’s Discussion and Analysis of Financial Condition and Results of Operations in our 2012 Form 10-K for a discussion of our critical accounting policies. There have been no significant changes to the application of our critical accounting policies during the first quarter for fiscal 2013.

Forward-Looking Statements

This report contains certain forward-looking statements as that term is defined in the Private Securities Litigation Reform Act of 1995. These forward-looking statements are based on beliefs of our management, as well as assumptions and estimates based on information available to us as of the dates such assumptions and estimates are made, and are subject to certain risks and uncertainties that could cause actual results to differ materially from historical results or those anticipated, depending on a variety of factors, including those factors discussed under Part II, Item 1A under the heading “Risk Factors” and to those set forth under Part I, Item 1A in our Annual Report on Form 10-K for the year ended May 31, 2012. Should one or more of those risks or uncertainties materialize adversely, or should underlying assumptions or estimates prove incorrect, actual results may vary materially from those described. Those events and uncertainties are difficult or impossible to predict accurately and many are beyond our control. We assume no obligation to update any forward-looking statements to reflect events or circumstances after the date of such statements or to reflect the occurrence of anticipated or unanticipated events.

Item 3 — Quantitative and Qualitative Disclosures About Market Risk

Our exposure to market risk includes fluctuating interest rates under our credit agreements and changes in foreign exchange rates.

Foreign Currency Risk. Revenues and expenses of our foreign operations are translated at average exchange rates during the period, and balance sheet accounts are translated at period-end exchange rates. Balance sheet translation adjustments are excluded from the results of operations and are recorded in stockholders’ equity as a component of accumulated other comprehensive loss. A hypothetical 10 percent devaluation of the U.S. dollar against foreign currencies would decrease our earnings by approximately $3 million.

Interest Rate Risk. Refer to the section Quantitative and Qualitative Disclosures about Market Risk in our Annual Report on Form 10-K for the year ended May 31, 2012. There were no significant changes during the quarter ended August 31, 2012.

Item 4 — Controls and Procedures

As required by Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, we conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as of August 31, 2012. This evaluation was carried out under the supervision and with participation of our Chief Executive Officer and Chief Financial Officer. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures. Therefore, effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives. Based upon our evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures are effective as of August 31, 2012, ensuring that information required to be disclosed in the reports that are filed under the Act is recorded, processed, summarized and reported in a timely manner.

There were no changes in our internal control over financial reporting during the first quarter ended August 31, 2012 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
