SoCalGas Urges Shareholders to Vote FOR Retirement of All Outstanding Shares of Preferred Stock at a Premium

At the Special Meeting, SoCalGas will seek approval from holders of its 6% Preferred Stock, par value $25.00, and 6% Preferred Stock, Series A, par value $25.00, to retire all outstanding shares of preferred stock in exchange for a cash payment of $31.00 per share, plus accrued and unpaid dividends to but excluding the retirement date. The cash payment represents a premium of more than 20% over the recent market prices, estimated fair value, and par value of the shares.

As part of our ongoing efforts to modernize our business and serve our stakeholders, SoCalGas is pursuing the proposed transaction to simplify its capital structure while delivering immediate value to shareholders. SoCalGas has filed a preliminary proxy statement for the Special Meeting with the U.S. Securities and Exchange Commission ("SEC") and, subject to the timing of SEC review, expects to file its definitive proxy statement on or about May 19, 2026, at which time shareholders as of the record date for the Special Meeting will be able to submit their votes.

SoCalGas urges all preferred shareholders to vote "FOR" this proposal in advance of the meeting. Copies of the proxy materials are available on SoCalGas' website at socalgas.com/about-us/special-shareholder-meeting.
