The Offer is made for the Issuer's Public Shares of IEnova, a Mexican company with listed securities on the Mexican Stock Exchange, and is subject to procedural and disclosure requirements in Mexico, which are different from those in the U.S.

See Section 7.20 of the Offering Memorandum "7. Terms of the Offer" - "Offer Closing Procedure" for additional information.

The settlement of the Offer shall be made exclusively through the payment of the Total Amount of the Offer, as described in the Offering Memorandum. Each Custodian shall be liable for delivering to each of its clients that is a beneficial owner of IEnova Public Shares the amount of cash consideration corresponding to the number of IEnova Public Shares validly tendered and not withdrawn from the Offer by each such beneficial owner.

The Broker-Dealer shall have no liability if it does not receive the Total Amount of the Offer from the Offeror.

Opinion from Issuer's Board of Directors:

For additional information, see Section 7.20 of the Offering Memorandum "7. Terms of the Offer - Offer Closing Procedure."

On June 28, 2021, with the participation of 97.03% (ninety-seven point zero three percent) of the shares representing the Issuer's capital stock, the Issuer held an extraordinary shareholders' meeting whereby it resolved, with the affirmative vote of 96.94% (ninety-six point ninety four percent) of the shares representative of its capital stock, among other things, to (i) cancel the registration of the Issuer's Shares from the RNV; and (ii) delist the Issuer's Shares from the BMV.

The extraordinary shareholders' meeting minutes, as documented in public deed 74,246 (seventy four thousand two hundred and forty six) granted by Patricio Garza Bandala, notary public number 195 (one hundred and ninety five) of Mexico City, is in process of being registered in the Public Registry of Commerce.

After consummation of the Offer and regardless of the results of the Offer, the Offeror intends to cause the Issuer to submit an application to the CNBV to cancel the registration of the Issuer's Shares in the RNV, and to request delisting of the Issuer's Shares from the BMV, in which case the Issuer will no longer be a publicly traded company (sociedad anónima bursátil) with listed equity securities subject to the LMV, although it will remain subject to certain other requirements of the LMV in connection with its prior public offerings of Mexican peso-denominated debt securities.

In the event the CNBV approves the cancellation of the Issuer Shares with the RNV and the BMV gives its favorable opinion for their delisting from the BMV, the Offeror will contribute to the Delisting Trust, and will maintain, during a minimum term of 6 (six) months starting on the date of the cancellation of the registration of the shares representing the capital stock of the Issuer with the RNV, sufficient funds to acquire, at the Price per Share, any Issuer's Public Shares not acquired through the Offer, in accordance with the terms of subsection (c), section I, of Article 108 of the LMV. In the event that any public shareholder of the Issuer does not participate and does not tender its Issuer's Public Shares in the Offer, or does not subsequently deliver its IEnova Public Shares to the aforementioned Delisting Trust, such shareholder will become a shareholder of a private company, and its Issuer's Public Shares will likely become illiquid, thus possibly affecting their price in a significant manner.

As disclosed by the Issuer by means of a current report (evento relevante) published through EMISNET on August 20, 2021, after the Issuer's Board of Directors received and reviewed the recommendation of its Corporate Practices Committee, the Issuer's Board of Directors approved by unanimous vote of the members of the Board who participated in the discussion and voting, among other things, to give a favorable opinion regarding Price per Share.

Certain members of the Board of Directors of the Issuer (including one member of its Corporate Practices Committee) constitute Related Persons of the Offeror and its Affiliates, and in order to avoid potential conflicts of interest, such Board members informed the Board of their relationship with the Offeror and abstained from discussion and voting at such Board meeting. Additionally, as required under applicable law, Board members of the Issuer disclosed that none of these members owned any Issuer's Public Shares and would not participate in the Offer, through the publication by IEnova of the same current report (evento relevante) through the EMISNET.

There was no opinion from an independent expert in connection with the Price per Share, as the Price per Share complied with the minimum parameters set forth in paragraph b), Section I of Article 108 of the LMV.
