AerCap Holdings N.V. Reports First Quarter 2010 Financial Results

Net spread, which is the margin earned on our leased assets, was $133 million for the first quarter of 2010, an increase of 18% over the first quarter of 2009.

Amsterdam, Netherlands; May 7, 2010 - AerCap Holdings N.V. (the “Company” or “AerCap”) (NYSE: AER) today announced the results of its operations for the first quarter ended March 31, 2010.

On March 25, 2010, AerCap completed an all-share acquisition of Genesis Lease Limited (“Genesis”), pursuant to which Genesis amalgamated with AerCap International Bermuda Limited, a subsidiary of AerCap (the ”Genesis Transaction”). The resulting amalgamated company continues as a subsidiary of AerCap. The Genesis Transaction is fully reflected in the AerCap Holdings N.V. consolidated balance sheet as of March 31, 2010. The Genesis Transaction has no impact on the AerCap Holdings N.V. first quarter 2010 income statement (including the number of outstanding shares used for earnings per share calculations) other than a one line item reflecting a $0.3 million amalgamation gain (net of transaction expenses and tax). The impact of the Genesis Transaction is also reflected in one line item in the AerCap Holdings N.V. first quarter 2010 consolidated cash flow statement (purchase of subsidiaries, net of cash acquired). From the second quarter of 2010, the Genesis Transaction will fully impact AerCap Holdings N.V.’s income statement and cash flow statement.

First Quarter 2010 Highlights

· First quarter 2010 net income was $34.4 million, compared with net income of $30.0 million for the same period in 2009. First quarter 2010 net income excluding the impact of the mark-to-market of interest rate caps and share-based compensation was $46.7 million, compared to net income of $31.5 million in the first quarter 2009 on the same basis.

· First quarter 2010 basic and diluted earnings per share were $0.40. First quarter 2010 basic and diluted earnings per share excluding the impact of the mark-to-market of interest rate caps and share-based compensation were $0.55.

· Net spread, the difference between basic lease rents and interest expense excluding the impact from the mark-to-market of interest rate caps, was $133.0 million in the first quarter of 2010 compared to $112.5 million in the first quarter of 2009, an increase of 18%. This measure reflects the increase in leasing income.

· Basic lease rents for the first quarter of 2010 were $165.8 million, compared to $141.4 million for the same period in 2009, an increase of 17%. Total lease revenue (basic rents, maintenance rents and end-of-lease compensation) for the first quarter of 2010 was $175.4 million, compared to $161.2 million for the same period in 2009, an increase of 9%.

· Sales revenue for the first quarter of 2010 was $182.4 million, compared to $41.7 million for the same period in 2009, and was generated from the sale of five aircraft, three engines and parts inventory.

· Total revenue for the first quarter of 2010 was $364.0 million, compared to $208.5 million for the same period in 2009. The increase was mainly due to the increase in sales revenue and an increase in lease revenues from higher basic lease rents.

· Committed purchases of aviation assets delivered or scheduled for delivery in 2010 are $2.2 billion, of which $0.9 billion closed in the first quarter of 2010.

· Total assets were $8.7 billion at March 31, 2010, an increase of 50% over total assets of $5.8 billion at March 31, 2009. The Genesis Transaction accounted for $1.6 billion of the increase in total assets (please refer to “Financial position” for details). The remaining $1.3 billion increase was driven primarily by deliveries of forward order aircraft.

Klaus Heinemann, CEO of AerCap, commented: “AerCap increased its flight equipment portfolio by 71% to $7.2 billion during the last twelve months, inclusive of the Genesis Transaction. For the remaining quarters of this year, we have further portfolio growth of $1.3 billion contracted and placed. Our revenue grew by 75% compared to the same quarter last year reflecting an improved market for sales. With such improvement, we also increased our net income (excluding the mark-to-market of interest rate caps and share-based compensation) by 48%. Finally, with a continued focus on liquidity, we expanded our total cash position by 38% to $440 million and improved our debt/equity ratio from 3.6 to 3.3. As a result of these efforts, AerCap is firmly established as the leading independent global aviation lessor with a sound balance sheet and ample liquidity as we enter a new cyclical upturn in our industry.”

AerCap’s CFO, Keith Helming, said: “We are pleased with our first quarter results. Our net spread increased 18% year-on-year, highlighting the continued growth in our lease earnings. AerCap also strengthened its cash position in 2010 through the completion of the Genesis Transaction and the signing of a debt financing agreement which funds are available for general corporate purposes. In addition, the integration of the Genesis Transaction is progressing well and is expected to be completed during the second quarter of 2010.”

Summary of Financial Results

AerCap recorded a first quarter 2010 net income of $34.4 million or $0.40 earnings per basic and diluted share. First quarter 2010 net income amount included net charges relating to mark-to-market of interest rate caps and share-based compensation of $12.3 million or $0.15 per basic and diluted share, net of tax. The after-tax charge relating to the mark-to-market of our interest rate caps was $11.6 million which reflects changes in forecasted interest rates and the after-tax charge from share-based compensation was $0.7 million.

Detailed Financial Data

Operating results

Total revenue in the first quarter of 2010 increased 75% compared to the first quarter of 2009. This increase resulted primarily from an increase in sales revenue and higher basic lease rents.

Net income for the first quarter of 2010 excluding the impact of mark-to-market of interest rate caps and share-based compensation increased by 48%. This increase was caused by higher income from the sale of assets and an increase in net spread.

Revenue breakdown

Basic lease rents were $165.8 million for the first quarter of 2010, an increase of 17% compared to the first quarter of 2009, as a result of our growing asset base. Our average lease assets increased by 32% to $5.4 billion compared to the first quarter of 2009. As shown in the table below, interest expense excluding the impact of the mark-to-market of interest rate caps was $32.8 million in the first quarter of 2010, a 13% increase compared to the first quarter of 2009. We refer to the difference in basic lease rents and interest expense on debt excluding the mark-to-market on interest rate caps as net spread, which increased 18% to $133.0 million in the first quarter of 2010 over the same period in 2009.

Notes Regarding Financial Information Presented In This Press Release

The financial information presented in this press release is not audited.

The following is a definition of non-GAAP measures used in this press release and a reconciliation of such measure to the most closely related GAAP measure:

Net income excluding the impact of mark-to-market of interest rate caps and share-based compensation. This measure is determined by adding non-cash charges related to the mark-to-market losses on our interest rate caps and share based compensation during the applicable period, net of related tax benefits, to GAAP net income. In addition to GAAP net income, we believe this measure may provide investors with supplemental information regarding our operational performance and may further assist investors in their understanding of our operational performance in relation to past and future reporting periods. We use interest rate caps to allow us to benefit from decreasing interest rates and protect against the negative impact of rising interest rates on our floating rate debt. Management determines the appropriate level of caps in any period with reference to the mix of floating and fixed cash inflows from our lease and other contracts. We do not apply hedge accounting to our interest rate caps. As a result, we recognize the change in fair value of the interest rate caps in our income statement during each period. Following is a reconciliation of net income excluding the impact of mark-to-market of interest rate caps and share-based compensation to net income for the three month periods ended March 31, 2010 and 2009:

Earnings per share excluding the impact of mark-to-market of interest rate caps and share-based compensation are determined by dividing the amount of net income excluding such impact by the average number of shares outstanding for that period. The average number of shares is based on a daily average.

Net spread (refer to second table under Revenue breakdown section of this press release). This measure is the difference between basic lease rents and interest expense excluding the impact from the mark-to-market of interest rate caps and non-recurring charges. We believe this measure may further assist investors in their understanding of the changes and trends related to the earnings of our leasing activities. This measure reflects the impact from changes in the number of aircraft leased, lease rates, utilization rates, as well as the impact from the use of interest rate caps instead of swaps to hedge our interest rate risk. The reconciliation of net spread to basic rents for the three month periods ended March 31, 2010 and 2009 is included above.
