Guarantees, Letters of Credit, and Surety Bonds — In connection with certain project financings (including tax equity transactions), acquisitions and dispositions, power purchases, EPC contracts, tax credit transfers, and other agreements, the Parent Company and its subsidiaries have expressly undertaken limited obligations and commitments, most of which will only be effective or will be terminated upon the occurrence of future events. In the normal course of business, the Parent Company and its subsidiaries have entered into various agreements, mainly guarantees and letters of credit, to provide financial or performance assurance to third parties on behalf of AES businesses. It is unlikely that the Parent Company or its subsidiaries would be required to perform or otherwise incur any material losses associated with guarantees of subsidiaries' or affiliates' obligations. These agreements are entered into primarily to support or enhance the creditworthiness otherwise achieved by a business on a stand-alone basis, thereby facilitating the availability of sufficient credit to accomplish their intended business purposes. Most of the contingent obligations relate to future performance commitments which the Company expects to fulfill within the normal course of business. Our tax equity and tax credit transfer guarantees typically consist of standard indemnifications of tax equity partners or tax credit purchasers in the event that an adverse determination arises due to a recapture event, tax controversy, or any breach by the AES project company of the representations in the shared equity agreement. The expiration dates of these guarantees vary from less than 1 year to no more than 26 years.

The following table summarizes the Parent Company’s consolidated contingent contractual obligations as of March 31, 2026. Amounts presented in the following table represent the Parent Company’s current undiscounted exposure to guarantees and the range of maximum undiscounted potential exposure per individual agreement. The maximum exposure is not reduced by the amounts, if any, that could be recovered under the recourse or collateralization provisions in the guarantees.

The following table summarizes our subsidiaries’ consolidated contingent contractual obligations as of March 31, 2026. These contingent contractual obligations are issued at the subsidiary level and are non-recourse to the Parent Company. Amounts presented in the following table represent our subsidiaries' current undiscounted exposure to guarantees and the range of maximum undiscounted potential exposure per individual agreement. The maximum exposure is not reduced by the amounts, if any, that could be recovered under the recourse or collateralization provisions in the guarantees.

Environmental — The Company periodically reviews its obligations as they relate to compliance with environmental laws, including site restoration and remediation. As of both March 31, 2026 and December 31, 2025, the Company recognized liabilities of $1 million for projected environmental remediation costs. These amounts are reported on the Condensed Consolidated Balance Sheets within Accrued and other liabilities and Other noncurrent liabilities. Due to the uncertainties associated with environmental assessment and remediation activities, future costs of compliance or remediation could be higher or lower than the amount currently accrued. Moreover, where no liability has been recognized, it is reasonably possible that the Company may be required to incur remediation costs or make expenditures in amounts that could be material but could not be estimated as of March 31, 2026. Unasserted claims are not included in the range of potential losses related to environmental matters until it is probable that a claim will be asserted and there is a reasonable possibility that the outcome will be unfavorable. In aggregate, the Company estimates the range of potential losses related to environmental matters, where estimable, to be between $1 million and $5 million. The amounts considered reasonably possible do not include amounts accrued as discussed above.

Litigation — The Company is involved in certain claims, suits, and legal proceedings in the normal course of business. The Company accrues for litigation and claims when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. The Company has recognized aggregate liabilities for all claims of approximately $14 million and $22 million as of March 31, 2026 and December 31, 2025, respectively. These amounts are reported on the Condensed Consolidated Balance Sheets within Accrued and other liabilities and Other noncurrent liabilities. A significant portion of these accrued liabilities relate to regulatory matters and commercial disputes in international jurisdictions. There can be no assurance that these accrued liabilities will be adequate to cover all existing and future claims or that we will have the liquidity to pay such claims as they arise.

Where no accrued liability has been recognized, it is reasonably possible that some matters could be decided unfavorably to the Company and could require the Company to pay damages or make expenditures in amounts that could be material but could not be estimated as of March 31, 2026. The material contingencies where a loss is reasonably possible primarily include disputes with offtakers, suppliers and EPC contractors; alleged breaches of contract; alleged violation of laws and regulations; income tax and non-income tax matters with tax authorities (including but not limited to tax disputes in Brazil and El Salvador); and regulatory matters. In aggregate, the Company estimates the range of potential losses, where estimable, related to these reasonably possible material contingencies to be between $98 million and $171 million. Included in this range is a reasonably possible legal contingency for environmental remediation costs related to Sul, a business the Company disposed of in 2016, estimated to be approximately R$15 million to R$60 million ($3 million to $11 million). The amounts considered reasonably possible do not include the amounts accrued, as discussed above. These material contingencies do not include income tax-related contingencies which are considered part of our uncertain tax positions.
