AES Reports Solid First Quarter Results and Reaffirms Full Year 2009 Earnings, Subsidiary Distributions and Proportional Free Cash Flow Guidance

• Earnings Per Share from Continuing Operations of $0.33 compared to $0.34 in 2008

• Adjusted Earnings Per Share of $0.37 compared to $0.35 in 2008

• Proportional Free Cash Flow, the Company’s share of Consolidated Free Cash Flow, increased $40 million to $203 million over same period last year

• Parent Company Liquidity strengthened through refinancing of $1.3 billion

ARLINGTON, VA, May 8, 2009 – The AES Corporation (NYSE: AES) today reported solid first quarter earnings. Significant contributions came from the Latin America generation businesses and North America utilities, as well as a performance incentive related to the management of Northern Kazakhstan businesses.

“We are pleased that AES’s share of free cash flow increased by $40 million as a result of improvements in working capital and expense reductions. Accordingly, we are reaffirming our 2009 earnings and proportional cash flow guidance. However, like other global companies, we are not immune to volatile foreign exchange rates or lower market prices, which will have an impact on working capital in Brazil and the Dominican Republic that will decrease the 2009 consolidated cash flow range by five percent,” said Paul Hanrahan, President and Chief Executive Officer. “With more than 95 percent of our more than 3,000 MW construction program contracted under long-term agreements and fully financed, we expect these projects to significantly contribute to our cash flow over the next three years.”

In addition, AES undertook a series of capital structure transactions in the quarter which will improve liquidity through 2010 and beyond. Regarding these initiatives, Victoria D. Harker, Executive Vice President and Chief Financial Officer, said, “Over the past several months, we continued to enhance our corporate liquidity through refinancings of $1.3 billion, which extended our debt maturities well beyond 2009. This included a renegotiation of our senior secured credit facility and a $535 million bond offering. These proceeds were used to reduce our $600 million unsecured credit facility, which will no longer be needed. At the subsidiary level, AES Gener’s $196 million bond offering provided the funds needed to complete the construction projects in Chile.”

First Quarter 2009 Financial Highlights (comparison of Q1 2009 vs. Q1 2008):

Quarter over quarter, the Company experienced foreign currency exchange losses of $130 million, and a $63 million margin reduction due to lower electricity prices and volume at several generation businesses. In addition, as a result of the sale of our Northern Kazakhstan businesses in 2008, there was a $26 million reduction of gross margin. However, there were several offsetting improvements from Latin America generation and North America utilities, as well as reduced operating expenses overall. Key factors were:

• Consolidated Cash Flow from Operating Activities of $376 million, compared to $470 million in 2008; primarily reflecting lower gross margin and changes in working capital; 2009 cash flow results do not include the $80 million from Kazakhstan management services in 2008 recognized as income in first quarter but not received until April 2009.

• Proportional Cash Flow from Operating Activities (a non-GAAP financial measure, see Appendix for definition and reconciliation) of $323 million, compared to $287 million in

the first quarter of 2008, primarily driven by improvements in working capital at the Company’s Asia Generation businesses. Proportional Free Cash Flow from Operating Activities reflects the economic interest of AES in the consolidated results.

• Consolidated Free Cash Flow (a non-GAAP financial measure, see Appendix for definition and reconciliation) of $220 million, compared to $291 million in 2008, 2009 results reflect lower Consolidated Operating Cash Flow offset in part by reduced maintenance capital expenditures.

• Proportional Free Cash Flow (a non-GAAP financial measure, see Appendix for definition and reconciliation), of $203 million, versus $163 million for the same period last year. Proportional Free Cash Flow reflects the economic interest of AES in the consolidated results.

• Consolidated Revenues decreased $703 million or 17% to $3.4 billion, primarily due to unfavorable foreign currency exchange rates of $578 million, of which approximately $400 million, or 69%, relates to devaluation of the Brazilian Real.

• Consolidated Gross Margin, which decreased $159 million or 15% to $883 million, due to unfavorable movements in foreign currency exchange rates of $130 million and lower electricity prices and volume at several generation businesses of $63 million. This decline was offset in part by improved operations across the Company’s global portfolio and higher availability at several generation businesses.

• Proportional Gross Margin (a non-GAAP financial measure, see Appendix for definition and reconciliation), declined by $152 million, or 22% due to lower electricity prices in New York and Argentina, the lack of contribution from the Northern Kazakhstan businesses sold in 2008, and unfavorable foreign currency exchange rates.

• Diluted Earnings from Continuing Operations of $0.33 per share, compared to $0.34 per share in 2008; the decrease was primarily driven by unfavorable impacts of foreign currency, offset in part by an $80 million or $0.12 per share performance incentive bonus, recognized as Other Income, associated with the management of the Company’s Northern Kazakhstan assets sold in 2008.

• Net Income attributable to AES of $218 million or $0.33 per share, compared to $233 million or $0.34 per share in 2008.

• Adjusted Earnings Per Share (a non-GAAP financial measure, see Appendix for definition and reconciliation) increased from $0.35 to $0.37; 2009 results exclude $0.03 of non-cash, unrealized foreign currency transaction losses.

Key 2009 Highlights:

• Finalized agreement with Kazakhmys PLC to end management of the Northern Kazakhstan businesses sold in 2008, for $182 million in total consideration, including a performance incentive bonus for 2008 management services. Of the $182 million, $80 million was received in April 2009; in January 2010 the balance will be received, which will be backed by investment grade letters of credit to be executed in the second quarter of 2009.

• Increased senior secured Revolver availability by $35 million to $785 million and extended the maturity date of $605 million of Revolver commitments from June 23, 2010 to July 5, 2011.

• Strengthened Parent Company Liquidity (a non-GAAP financial measure) by issuing $535 million of 9.75% senior unsecured notes due 2016, netting proceeds of approximately $492 million; majority of proceeds used to replace $425 million of senior unsecured facility maturing in 2010.

• The Company’s subsidiary, AES Gener, issued $196 million of 8.50% ten year bonds to fund its construction program in Chile.

• Made substantive progress on the Company’s more than 3,000 MW construction program. Commenced commercial operation of 130 MW Santa Lidia diesel facility in Chile.

• Expanded solar portfolio by 8 MW in Spain through AES Solar Energy, the Company’s joint venture with Riverstone, increasing total solar capacity to 32 MW.

2009 Guidance

• The Company is reaffirming its full year 2009 guidance for Adjusted Earnings Per Share, Proportional Cash Flow from Operating Activities and Proportional Free Cash Flow.

• The Company is lowering its guidance range for Consolidated Cash Flow from Operating Activities and Consolidated Free Cash Flow, which is being decreased by $100 million primarily due to working capital changes in Brazil. The revised Consolidated Operating Free Cash Flow guidance range for the full year is $2.0 to $2.2 billion; the guidance range for Consolidated Free Cash Flow (a non-GAAP financial measure) is $1.3 to $1.5 billion.

⁽¹⁾ Adjusted earnings per share (a non-GAAP financial measure) is defined as diluted earnings per share from continuing operations excluding gains or losses of the consolidated entity due to (a) mark-to-market amounts related to FAS 133 derivative transactions, (b) unrealized foreign currency gains or losses, (c) significant gains or losses due to dispositions and acquisitions of business interests, (d) significant losses due to impairments, and (e) costs due to the early retirement of debt. AES believes that adjusted earnings per share better reflects the underlying business performance of the Company, and is considered in the Company’s internal evaluation of financial performance. Factors in this determination include the variability due to mark-to-market gains or losses related to derivative transactions, currency gains or losses, losses due to impairments and strategic decisions to dispose or acquire business interests or retired debt which affect results in a given period or periods.

⁽²⁾ Amount includes: Kazakhstan net gain of $13 million or $0.02 related to the reversal of withholding tax contingency. There is no tax expense associated with the Kazakhstan gain.

⁽³⁾ Amount includes: An impairment of the Company’s investment in coal to gas technology of $10 million or $0.02. There is no tax benefit associated with the coal to gas technology project impairment.

⁽⁴⁾ Amount includes: South Africa peaker development cost write-off of $19 million ($17 million net of taxes or $0.03); and Uruguaiana impairment of $14 million ($6 million net of minority interest or $0.01). There is no tax benefit associated with the Uruguaiana impairment.

⁽⁵⁾ Free cash flow (a non-GAAP financial measure) is defined as net cash from operating activities less maintenance capital expenditures (including environmental capital expenditures). AES believes that free cash flow is a useful measure for evaluating our financial condition because it represents the amount of cash provided by operations, less maintenance capital expenditures as defined by our businesses, that may be available for investing or repaying debt.

⁽¹⁾ Subsidiary distributions should not be construed as an alternative to Net Cash Provided by Operating Activities which are determined in accordance with GAAP. Subsidiary distributions are important to the Parent Company because the Parent Company is a holding company that does not derive any significant direct revenues from its own activities but instead relies on its subsidiaries’ business activities and the resultant distributions to fund the debt service, investment and other cash needs of the holding company. The reconciliation of difference between the subsidiary distributions and the Net Cash Provided by Operating Activities consists of cash generated from operating activities that is retained at the subsidiaries for a variety of reasons which are both discretionary and non-discretionary in nature. These factors include, but are not limited to, retention of cash to fund capital expenditures at the subsidiary, cash retention associated with non-recourse debt covenant restrictions and related debt service requirements at the subsidiaries, retention of cash related to sufficiency of local GAAP statutory retained earnings at the subsidiaries, retention of cash for working capital needs at the subsidiaries, and other similar timing differences between when the cash is generated at the subsidiaries and when it reaches the Parent Company and related holding companies.

⁽²⁾ Parent Company Liquidity is defined as cash at the Parent Company plus availability under corporate revolver plus cash at qualifying holding companies (QHCs). AES believes that unconsolidated Parent Company liquidity is important to the liquidity position of AES as a Parent Company because of the non-recourse nature of most of AES’s indebtedness.

⁽³⁾ The cash held at QHCs represents cash sent to subsidiaries of the company domiciled outside of the US. Such subsidiaries had no contractual restrictions on their ability to send cash to AES, the Parent Company. Cash at those subsidiaries was used for investment and related activities outside of the US. These investments included equity investments and loans to other foreign subsidiaries as well as development and general costs and expenses incurred outside the US. Since the cash held by these QHCs is available to the Parent, AES uses the combined measure of subsidiary distributions to Parent and QHCs as a useful measure of cash available to the Parent to meet its international liquidity needs.

⁽¹⁾ The AES Corporation (the “Company”) is a holding company that derives its income and cash flows from the activities of its subsidiaries, some of which may not be wholly-owned by the Company. Accordingly, the Company has presented certain financial metrics which are defined as Proportional (a non-GAAP financial measure). Proportional metrics present the Company’s estimate of its share in the economics of the underlying metric. The Company believes that the Proportional metrics are useful to investors because they exclude the economic share in the metric presented that is held by non-AES shareholders. For example, Operating Cash Flow is a GAAP metric which presents the Company’s cash flow from operations on a consolidated basis, including operating cash flow allocable to noncontrolling interests. Proportional Operating Cash Flow removes the share of operating cash flow allocable to noncontrolling interests and therefore may act as an aid in the valuation the Company. Proportional measures are considered in the Company’s internal evaluation of financial performance. Proportional metrics are reconciled to the nearest GAAP measure. Certain assumptions have been made to estimate our proportional financial measures.

These assumptions include: (i) the Company’s economic interest has been calculated based on a blended rate for each consolidated business when such business represents multiple legal entities; (ii) the Company’s economic interest may differ from the percentage implied by the recorded net income or loss attributable to noncontrolling interests or dividends paid during a given period; (iii) the Company’s economic interest for entities accounted for using the hypothetical liquidation at book value method is 100%; (iv) individual operating performance of the Company’s equity method investments is not reflected and (v) all intercompany amounts have been excluded as applicable.

⁽²⁾ Adjustment factors include $0.10 per share of addbacks related primarily to estimated unrealized foreign currency and FAS 133 derivative losses as well as a ($0.16) per share gain on sale related to Northern Kazakhstan businesses
