IENOVA ANNOUNCES BOARD OPINION

ON FINAL NON-BINDING EXCHANGE OFFER CONSIDERATION

PROPOSED BY SEMPRA ENERGY

Mexico City, April 14, 2021 – Infraestructura Energética Nova, S.A.B. de C.V. (“IEnova”), further to its material event filing dated April 12, 2021, announced that at an extraordinary meeting of its Board of Directors (the “Board of Directors”) held on April 14, 2021 (the “Meeting”), with attendance by all the members of the Board of Directors and abstentions from discussion and voting by those members of the Board of Directors who expressed a conflict of interest, the directors participating at the Meeting unanimously resolved, among other things, to vote in favor of opining that the equity consideration proposed by Sempra Energy (“Sempra”) in connection with Sempra’s previously announced offer to acquire all of the issued and outstanding publicly held ordinary shares of IEnova in exchange for Sempra common stock (the “Exchange Offer”) is fair to IEnova shareholders from a financial point of view. The equity consideration proposed by Sempra in connection with the Exchange Offer was expressed in an exchange ratio (the “Exchange Ratio”) set forth in a non-binding offer letter, dated April 12, 2021 (the “Final Offer Letter”), from Sempra to the Corporate Practices Committee of IEnova’s Board of Directors (the “Corporate Practices Committee”). The publicly held ordinary shares of IEnova represent approximately 29.83% of IEnova’s issued and outstanding share capital. The Board of Directors evaluated the equity consideration proposed by Sempra in the Exchange Offer by applying the Exchange Ratio and taking into account the prevailing market price for Sempra common stock and the Ps./U.S.$ exchange rate as of the close of market on April 13, 2021.

The opinion of the Board of Directors was made in conformity with the recommendation of the Corporate Practices Committee, which recommendation was based, among other factors, on the opinion, dated April 14, 2021 (the “Independent Advisor Opinion”), issued by J.P. Morgan Securities LLC, as independent financial advisor to the Corporate Practices Committee in connection with the Exchange Offer (the “Independent Advisor”). In the Independent Advisor Opinion, the Independent Advisor opined on the fairness of the equity consideration proposed by Sempra in the Exchange Offer to IEnova shareholders from a financial point of view. A copy of the Independent Advisor Opinion is attached.

At the Meeting, the Board of Directors reviewed written certifications by the members of the Board of Directors, including IEnova’s Chief Executive Officer, with respect to the number of IEnova ordinary shares held by such members and their intention with respect to such ordinary shares in connection with the Exchange Offer, as follows:

The Board of Directors also reviewed the conflicts of interest expressed at the Meeting by Randall Lee Clark, Faisel Hussain Khan, Jennifer Frances Jett, Trevor Ian Mihalik, Erle Allen Nye, Jr., Peter Ronan Wall, Lisa Glatch, Tania Ortiz Mena López Negrete, Carlos Ruíz Sacristán and Vanesa Madero Mabama in connection with their participation and presence during discussion and voting on all matters related to the Exchange Offer, including with respect to the Final Offer Letter and

the opinion of the Board of Directors required by Article 101 of the Mexican Securities Market Law (Ley del Mercado de Valores). Any such abstentions due to conflicts of interest did not affect the required quorum for the Meeting.
