INFRAESTRUCTURA ENERGÉTICA NOVA, S.A.P.I. DE C.V. (IEnova) announced that it is soliciting (the "Consent Solicitations") consents (the "Consents") from holders (the "Holders") of IEnova's outstanding 3.750% Notes due 2028 (the "2028 Notes"), 4.875% Senior Notes due 2048 (the "2048 Notes") and 4.750% Senior Notes due 2051 (the "2051 Notes" and, together with the 2028 Notes and the 2048 Notes, the "Notes" and each a "Series of Notes") as of 5:00 p.m.New York City time, on December 7, 2022 (the "Record Date") to effect amendments to each of the indentures governing the Notes (each, an "Indenture" and collectively, the "Indentures"), as described below, upon the terms and subject to the conditions set forth in the Consent Solicitation Statement, dated December 8, 2022 (as may be amended or supplemented from time to time, the "Consent Solicitation Statement"). The Consent Solicitations will expire at 5:00 p.m.New York City time, on December 16, 2022 (such time and date, as the same may be extended from time to time, the "Expiration Date"). IEnova is soliciting Consents in order to amend the definition of "IFRS" in each Indenture so that the term encompasses not only International Financial Reporting Standards but also U.S. Generally Accepted Accounting Principles ("GAAP"), as further described under "The Proposed Amendments" in the Consent Solicitation Statement (the "Proposed Amendments").

Following the creation of the Sempra Infrastructure platform in 2021 and the delisting of IEnova's common stock from the Mexican Stock Exchange, in order to simplify IEnova's internal reporting to align with that of its parent, Sempra Infrastructure, IEnova wishes to adopt the same set of accounting standards as Sempra Infrastructure. The definition of "IFRS" across all Indentures is that IFRS means the International Financial Reporting Standards adopted by the International Accounting Standards Board. Accordingly, IEnova is requesting consent from Holders of each Series of Notes to amend the definition of "IFRS" in each Indenture to also include GAAP.

For the actual text of the Proposed Amendments, see "The Proposed Amendments" in the Consent Solicitation Statement. Except for the Proposed Amendments, all of the existing terms of each Indenture will remain unchanged. The obligation to pay (or cause to be paid) the Consent Payment for valid and unrevoked Consents to the Proposed Amendments for each Series of Notes is subject to and conditioned upon (i) the receipt of the Requisite Consents (as defined below) for such Series of Notes on or prior to the applicable Expiration Date for such Notes, (ii) the receipt of the Requisite Consents and the adoption of the Proposed Amendments with respect to each other Series of Notes and (iii) the absence of any law or regulation, and the absence of any injunction or action or other proceeding (pending or threatened), that (in the case of any action or proceeding if adversely determined) would make unlawful or invalid or enjoin or delay the implementation of the applicable Proposed Amendments, the entering into of the applicable Supplemental Indenture (as defined below) or the payment of the applicable Consent Payment to the Holders of that Series of Notes or that would question the legality or validity thereof (collectively, the "Consent Conditions").

If the Holders of at least a majority of the aggregate outstanding principal amount of a Series of Notes validly deliver and do not validly revoke Consents to the applicable Proposed Amendments (the "Requisite Consents"), IEnova and, upon receipt of an officers' certificate and an opinion of counsel, the trustee shall execute a supplemental indenture (each, a "Supplemental Indenture") to the applicable Indenture effecting the Proposed Amendments. The time and date on which a Supplemental Indenture is executed is hereinafter referred to as the "Consent Time" with respect to the applicable Series of Notes. Consents to the Proposed Amendments for any Series of Notes may not be revoked at any time after the earlier of the applicable Consent Time and 5:00 p.m., New York City time, December 16, 2022 (such time, as may be extended by IEnova, in its sole discretion for one or more Series of Notes, the "Revocation Deadline"), even if the applicable Revocation Deadline for such Notes is later than such Consent Time.

Although each Supplemental Indenture and the related Proposed Amendments will become effective immediately upon execution at the applicable Consent Time, such Proposed Amendments will not be operative until the applicable Consent Payment is paid to The Depository Trust Company ("DTC") for the benefit of the applicable Holders on the Settlement Date. IEnova expects to pay, or cause to be paid, the applicable Consent Payment to DTC for the benefit of the applicable Holders within two business days of the Expiration Date and upon the satisfaction or waiver of all Consent Conditions with respect to the applicable Notes (such date with respect to the applicable Series of Notes, the applicable "Settlement Date"). Once a Supplemental Indenture is effective, any Consents given with respect to the applicable Series of Notes may not be revoked and all Holders, including non-consenting holders, and their respective transferees will be bound by the terms thereof.

If the applicable Consent Time is earlier than the applicable Revocation Deadline, then such Consent Time will be the latest time by which Holders can revoke Consents. If the Consent Conditions are not satisfied or waived with respect to a Series of Notes, no Consent Payment with respect to such Notes will be paid to any Holder thereof.
