As Representatives of the several Underwriters

Ladies and Gentlemen:

Sempra, a California corporation (the “Company”), confirms its agreement (this “Agreement”) with each of the Underwriters named in Schedule I hereto (collectively, the “Underwriters,” which term shall also include any underwriter substituted as hereinafter provided in Section 9 hereof), for whom BofA Securities, Inc., Mizuho Securities USA LLC, RBC Capital Markets, LLC and Scotia Capital (USA) Inc. are acting as representatives (the “Representatives”), with respect to the issue and sale by the Company and the purchase by the Underwriters, acting severally and not jointly, of $600,000,000 aggregate principal amount of the Company’s 6.875% Fixed-to-Fixed Reset Rate Junior Subordinated Notes due 2054 (the “Securities”). The Securities are to be issued pursuant to an indenture dated as of June 26, 2019 (the “Indenture”) between the Company and U.S. Bank Trust Company, National Association (the “Trustee”), as successor trustee. The term “Indenture,” as used herein, includes the Officers’ Certificate (as defined in the Indenture) to be dated March 14, 2024 establishing the form and terms of the Securities pursuant to Sections 201 and 301 of the Indenture.

The Company has filed with the Securities and Exchange Commission (the “Commission”) an automatic shelf registration statement on Form S-3 (File No. 333-272237), which registration statement became effective upon filing under Rule 462(e) of the rules and regulations of the Commission (the “Rules and Regulations”) under the Securities Act of 1933, as amended (the “Act”). Such registration statement covers the registration of the Securities (among other securities) under the Act. Such registration statement, as amended through the date hereof (including by any post-effective amendments thereto) and including the information deemed pursuant to Rule 430B under the Rules and Regulations to be part of the registration statement at the time of its effectiveness with respect to the offering contemplated by this Agreement and all documents incorporated or deemed to be incorporated by reference therein through the date hereof, but excluding any Form T-1 (as defined below), is hereinafter referred to as the “Registration Statement.” The Company proposes to file with the Commission pursuant to Rule 424(b) of the Rules and Regulations the Prospectus Supplement (as defined in Section 5(h) hereof) relating to the Securities and the prospectus dated May 26, 2023 (the “Base Prospectus”), and has previously advised you of all further information (financial and other) with respect to the Company set forth therein. The Base Prospectus together with the Prospectus Supplement, in their respective forms on the date hereof (being the forms in which they are to be filed with the Commission pursuant to Rule 424(b) of the Rules and Regulations), including all documents incorporated or deemed to be incorporated by reference therein through the date hereof, are hereinafter referred to as, collectively, the “Prospectus,” except that if any revised prospectus or prospectus supplement shall be provided to the Underwriters by the Company for use in connection with the offering and sale of the Securities which differs from the Prospectus (whether or not such revised prospectus or prospectus supplement is required to be filed by the Company pursuant to Rule 424(b) of the Rules and Regulations), the term “Prospectus” shall refer to such revised prospectus or prospectus supplement, as the case may be, from and after the time it is first provided to the Underwriters for such use. The term “Preliminary Prospectus,” as used in this Agreement, means the preliminary prospectus supplement dated March 11, 2024 and filed with the Commission pursuant to Rule 424(b) of the Rules and Regulations, together with the Base Prospectus used with such preliminary prospectus supplement in connection with the marketing of the Securities, in each case as amended or supplemented by the Company, including all documents incorporated or deemed to be incorporated by reference therein through the date thereof. Unless the context otherwise requires, all references in this Agreement to documents, financial statements and schedules and other information which is “contained,” “included,” “stated,” “described in” or “referred to” in the Registration Statement, the Preliminary Prospectus or the Prospectus (and all other references of like import) shall be deemed to mean and include all such documents, financial statements and schedules and other information which is or is deemed to be incorporated by reference in the Registration Statement, the Preliminary Prospectus or the Prospectus, as the case may be; and all references in this Agreement to amendments or supplements to the Registration Statement, the Preliminary Prospectus or the Prospectus shall be deemed to mean and include the filing of any document under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), after the date of this Agreement which is or is deemed to be incorporated by reference in the Registration Statement, the Preliminary Prospectus or the Prospectus, as the case may be.

The Prospectus, at the Representation Date (unless the term “Prospectus” refers to a prospectus which has been provided to the Underwriters by the Company for use in connection with the offering of the Securities which differs from the Prospectus filed with the Commission pursuant to Rule 424(b) of the Rules and Regulations, in which case at the time it is first provided to the Underwriters for such use) and at the Time of Delivery, does not and will not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that the representations and warranties in this subsection (d) shall not apply to statements in or omissions from the Registration Statement or Prospectus made in reliance upon and in conformity with information furnished to the Company in writing by any Underwriter through the Representatives expressly for use in the Registration Statement or the Prospectus or the information contained in any Statement of Eligibility and Qualification of a trustee under the Trust Indenture Act filed as an exhibit to the Registration Statement (a “Form T-1”).

(d) Promptly from time to time to take such action as the Representatives may reasonably request to qualify the Securities for offering and sale under the securities laws of such domestic jurisdictions and (with the prior consent of the Company) foreign jurisdictions as the Representatives may request and to comply with such laws so as to permit the continuance of sales and dealings therein in such jurisdictions for as long as may be necessary to complete the distribution of the Securities, provided that in connection therewith the Company shall not be required to qualify as a foreign corporation or to file a general consent to service of process in any jurisdiction;

(g) During the period beginning on and including the date hereof and continuing to and including the later of (i) the termination of trading restrictions for the Securities, as notified to the Company by the Representatives, but only if the Representatives shall have notified the Company in writing at the Time of Delivery that such trading restrictions have not been terminated, and (ii) the Time of Delivery, not to offer, sell, contract to sell, grant any option for the sale of or otherwise dispose of any Securities, any debt securities of the Company which are substantially similar to the Securities (“Similar Securities”) or any

securities convertible into, exchangeable into or exercisable for any Securities or Similar Securities, without the prior written consent of the Representatives, provided that this subparagraph (g) shall not apply to the offer, issuance or sale of, or any contract to sell, (i) the Securities to the Underwriters pursuant to this Agreement, (ii) commercial paper or other debt securities with scheduled maturities of less than one year or (iii) any Senior Indebtedness (as defined in the Prospectus Supplement under the caption “Description of the Notes—Subordination”). For purposes of clarity, it is understood and agreed that the term Similar Securities, as used in this subparagraph (g), excludes (i) commercial paper or other debt securities with scheduled maturities of less than one year or (ii) any Senior Indebtedness (as defined in the Prospectus Supplement under the caption “Description of the Notes—Subordination”);

(h) Immediately following the execution of this Agreement, the Company will prepare a prospectus supplement, dated the date hereof (the “Prospectus Supplement”), containing the terms of the Securities, the plan of distribution thereof and such other information as may be required by the Act or the Rules and Regulations or as the Representatives and the Company deem appropriate, and will file or transmit for filing with the Commission in accordance with Rule 424(b) of the Rules and Regulations copies of the Prospectus (including such Prospectus Supplement);

(i) To apply the net proceeds from the sale of the Securities as set forth in the Prospectus; and

(j) The Company represents and agrees that, unless it obtains the prior consent of the Representatives, and each Underwriter represents and agrees that, unless it obtains the prior consent of the Company and the Representatives, it has not made and will not make any offer relating to the Securities that would constitute an Issuer Free Writing Prospectus, or that would otherwise constitute a “free writing prospectus,” as defined in Rule 405, required to be filed with the Commission; provided, however, that the prior consent of the Representatives and the Company shall be deemed to have been given in respect of the Final Term Sheet and any other Issuer Free Writing Prospectuses included in Schedule II hereto; and provided further, however, that prior to the preparation of the Final Term Sheet in accordance with Section 5(b), the Underwriters are authorized to use the information with respect to the final terms of the Securities in communications conveying information relating to the offering to investors. Any such free writing prospectus consented to by the Company and the Representatives or otherwise permitted by the immediately preceding sentence is hereinafter referred to as a “Permitted Free Writing Prospectus.” For purposes of clarity, it is understood and agreed that the term Issuer Free Writing Prospectus, as used in this Agreement, includes all Permitted Free Writing Prospectuses.

6. The Company covenants and agrees with the several Underwriters that the Company will pay or cause to be paid the following: (i) the fees, disbursements and expenses of the Company’s counsel and accountants in connection with the registration of the Securities under the Act and all other expenses in connection with the preparation, printing and filing of the Registration Statement, the Preliminary Prospectus, any Permitted Free Writing Prospectus and the Prospectus and amendments and supplements thereto and the mailing and delivering of copies thereof to the Underwriters and dealers; (ii) the cost of printing or producing any

13

agreement among Underwriters, this Agreement, the Indenture, any Blue Sky and Legal Investment Memoranda, closing documents (including any compilations thereof) and any other documents in connection with the offering, purchase, sale and delivery of the Securities; (iii) all expenses in connection with the qualification of the Securities for offering and sale under state securities laws as provided in Section 5(d) hereof, including the reasonable fees and disbursements of counsel for the Underwriters in connection with such qualification and in connection with the Blue Sky and Legal Investment Memoranda; (iv) any fees charged by securities rating services for rating the Securities; (v) any filing fees incident to, and the reasonable fees and disbursements of counsel for the Underwriters in connection with, any required review by The Financial Industry Regulatory Authority, Inc. of the terms of the sale of the Securities (up to a maximum aggregate amount of $5,000); (vi) the cost of preparing the Securities; (vii) the fees and expenses of the Trustee and any agent of the Trustee and the reasonable fees and disbursements of counsel for the Trustee in connection with the Indenture and the Securities; and (viii) all other costs and expenses incident to the performance of its obligations hereunder which are not otherwise specifically provided for in this Section. It is understood, however, that, except as provided in this Section, and Sections 8 and 11 hereof, the Underwriters will pay all of their own costs and expenses, including the fees of their counsel, transfer taxes on resale of any of the Securities by them, and any advertising expenses connected with any offers they may make.

7. The obligations of the Underwriters shall be subject, in the discretion of the Representatives, to the condition that all representations and warranties and other statements of the Company in or incorporated by reference in this Agreement are, at and as of the Time of Delivery, true and correct, the condition that the Company shall have performed all of its obligations hereunder theretofore to be performed, and the following additional conditions:

(a) The Prospectus, as amended or supplemented, shall have been filed with the Commission pursuant to Rule 424(b) within the applicable time period prescribed for such filing (without reliance on Rule 424(b)(8) of the Rules and Regulations and in accordance with Section 5(a) hereof); no stop order suspending the effectiveness of the Registration Statement or any part thereof shall have been issued and no proceeding for that purpose shall have been initiated or threatened by the Commission; and all requests for additional information from the Commission shall have been complied with to the Representatives’ reasonable satisfaction.

(b) Counsel for the Underwriters shall have furnished to the Representatives such written opinion or opinions, dated the Time of Delivery, with respect to the Registration Statement and the Prospectus, as amended or supplemented, as well as such other related matters as the Representatives may reasonably request, and such counsel shall have received such papers and information as they may reasonably request to enable them to pass upon such matters.

(c) [Intentionally Omitted]

(d) Latham & Watkins LLP shall have furnished to the Representatives their written opinion or opinions and negative assurances letter, dated the Time of Delivery, in the forms previously agreed and satisfactory to the Representatives.

14

(e) On the date hereof at a time prior to the execution of this Agreement, Deloitte & Touche LLP shall have furnished to the Representatives a letter with respect to the Company, dated the date hereof, in form and substance reasonably satisfactory to the Representatives, containing statements and information of the type ordinarily included in accountants’ “comfort letters” to underwriters, and, at the Time of Delivery, Deloitte & Touche LLP shall have furnished to the Representatives a letter dated the Time of Delivery, reaffirming the statements made in their letter dated the date hereof, except that the specified date referred to in such letter delivered on the Time of Delivery shall be a date not more than three days prior to the Time of Delivery, and with respect to such letter dated the Time of Delivery, as to such other matters as the Representatives may reasonably request and in form and substance reasonably satisfactory to the Representatives.

(f) On the date hereof at a time prior to the execution of this Agreement, Deloitte & Touche LLP shall have furnished to the Representatives a letter with respect to Oncor Holdings, dated the date hereof, in form and substance reasonably satisfactory to the Representatives, containing statements and information of the type ordinarily included in accountants’ “comfort letters” to underwriters, and, at the Time of Delivery, Deloitte & Touche LLP shall have furnished to the Representatives a letter dated the Time of Delivery, reaffirming the statements made in their letter dated the date hereof, except that the specified date referred to in such letter delivered on the Time of Delivery shall be a date not more than three days prior to the Time of Delivery, and with respect to such letter dated the Time of Delivery, as to such other matters as the Representatives may reasonably request and in form and substance reasonably satisfactory to the Representatives.

(g) (i) The Company and its subsidiaries, taken as a whole, shall have not sustained since the date of the latest audited financial statements included or incorporated by reference in the Prospectus, as amended prior to the date hereof, any material loss or interference with its business from fire, explosion, flood or other calamity, whether or not covered by insurance, or from any labor dispute or court or governmental action, order or decree, otherwise than as set forth or contemplated in the Pricing Disclosure Package and the Prospectus, as amended prior to the date hereof, and (ii) since the respective dates as of which information is given in the Pricing Disclosure Package and the Prospectus, as amended prior to the date hereof, there shall not have been any material change in the capital stock or long-term debt of the Company or any of its subsidiaries or any material adverse change, or any development involving a prospective material adverse change, in or affecting the general affairs, management or consolidated financial position, shareholders’ equity or results of operations of the Company and its subsidiaries, taken as a whole, in each case otherwise than as set forth or contemplated in the Pricing Disclosure Package and the Prospectus, as amended prior to the date hereof, the effect of which, in any such case described in clause (i) or (ii), is in the judgment of the Representatives so material and adverse to the Company and its subsidiaries, taken as a whole, as to make it impracticable or inadvisable to proceed with the public offering or the delivery of the Securities on the terms and in the manner contemplated in the Pricing Disclosure Package and the Prospectus as first amended or supplemented.

(h) At or after the Applicable Time (i) no downgrading shall have occurred in the rating accorded any of the Company’s debt securities by any “nationally recognized statistical rating organization,” as that term is defined by the Commission for purposes of Section 3(a)(62) under the Exchange Act, and (ii) no such organization shall have publicly announced that it has under surveillance or review, with possible negative implications, its rating of any of the Company’s debt securities.

(j) The Company shall have complied with the provisions of Section 5(e) hereof with respect to the furnishing of prospectuses on the second business day succeeding the date hereof.

(k) The Company shall have furnished or caused to be furnished to the Representatives at the Time of Delivery a certificate of officers of the Company satisfactory to the Representatives as to the accuracy of the representations and warranties of the Company herein at and as of the Time of Delivery, as to the performance by the Company of all of its obligations hereunder to be performed at or prior to the Time of Delivery, as to the matters set forth in subsections (a) and (g) of this Section and as to such other matters as the Representatives may reasonably request.

8. (a) The Company will indemnify and hold harmless each Underwriter against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Preliminary Prospectus, the Registration Statement, any Issuer Free Writing Prospectus, the Prospectus or any other prospectus relating to the Securities, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Preliminary Prospectus, the Registration Statement, any Issuer Free Writing Prospectus, the Prospectus or any other prospectus relating to the Securities or any amendment or supplement thereto in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives expressly for use therein.

16

(b) Each Underwriter, severally and not jointly, will indemnify and hold harmless the Company against any losses, claims, damages or liabilities to which the Company may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Preliminary Prospectus, the Registration Statement, any Issuer Free Writing Prospectus, the Prospectus or any other prospectus relating to the Securities, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Preliminary Prospectus, the Registration Statement, any Issuer Free Writing Prospectus, the Prospectus or any other prospectus relating to the Securities, or any such amendment or supplement thereto in reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Representatives expressly for use therein, it being understood and agreed that the only such information consists of the following: the information in the fourth paragraph of text under the caption “Underwriting (Conflicts of Interest)” in the Preliminary Prospectus and the Prospectus concerning the terms of the offering by the Underwriters, and the information in the eighth, ninth, tenth and eleventh paragraphs of text (solely with respect to the statements attributable to the Underwriters) under the caption “Underwriting (Conflicts of Interest)” in the Preliminary Prospectus and the Prospectus, insofar as such information relates to market making, stabilization, penalty bids, overallotment, short positions and purchases to cover short positions by the Underwriters; and will reimburse the Company for any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such action or claim as such expenses are incurred.

(c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party under such subsection to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability otherwise than under such subsection. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation; provided, however, that the Representatives shall have the right to employ counsel to represent jointly the Underwriters and their respective directors, officers, employees, agents and controlling persons who may be

17

subject to liability arising out of any claim in respect of which indemnity may be sought by the Underwriters against the Company under this Section 8, if the Representatives shall have reasonably concluded that there may be one or more legal defenses available to the Underwriters and their respective directors, officers, employees, agents and controlling persons that are different from or additional to those available to the Company and its officers, directors, employees and controlling persons, and in each case the fees and expenses of a single separate counsel for the Underwriters and their respective directors, officers, employees, agents and controlling persons (in addition to local counsel) shall be paid by the Company. The indemnifying party shall not be liable for any settlement or compromise of, or the consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification may be sought hereunder effected without the prior written consent of the indemnifying party (which consent shall not be unreasonably withheld), but, if settled or compromised with the indemnifying party’s consent, or if judgment shall be entered following consent to the entry of such judgment given with the indemnifying party’s consent, or if there shall otherwise be a final judgment for the plaintiff, the indemnifying party agrees to indemnify and hold harmless each indemnified party against any and all losses, claims, damages, liabilities and expenses, joint or several, by reason of such settlement, compromise or judgment, as the case may be. No indemnifying party shall, without the prior written consent of the indemnified party (which consent shall not be unreasonably withheld), effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d) If the indemnification provided for in this Section 8 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other from the offering of the Securities contemplated by this Agreement. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under subsection (c) above, then in each case each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering of the Securities contemplated by this Agreement (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged

18

omission to state a material fact relates to information supplied by the Company on the one hand or the Underwriters on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this subsection (d) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The obligations of the Underwriters in this subsection (d) to contribute are several in proportion to their respective underwriting obligations with respect to the Securities and not joint.

(e) The obligations of the Company under this Section 8 shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and conditions, to each director, officer, employee and agent of any Underwriter and each person, if any, who controls any Underwriter within the meaning of the Act; and the obligations of the Underwriters under this Section 8 shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each officer, director and employee of the Company and to each person, if any, who controls the Company within the meaning of the Act.

9. (a) If any Underwriter shall default in its obligation to purchase the Securities which it has agreed to purchase under this Agreement, the Representatives may in their discretion arrange for themselves or another party or other parties to purchase such Securities on the terms contained herein. If within thirty-six hours after such default by any Underwriter the Representatives do not arrange for the purchase of such Securities, then the Company shall be entitled to a further period of thirty-six hours within which to procure another party or other parties reasonably satisfactory to the Representatives to purchase such Securities on such terms. In the event that, within the respective prescribed period, the Representatives notify the Company that they have so arranged for the purchase of such Securities, or the Company notifies the Representatives that it has so arranged for the purchase of such Securities, the Representatives or the Company shall have the right to postpone the Time of Delivery for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus, as amended or supplemented, or in any other documents or arrangements, and the Company agrees to file promptly any amendments or supplements to the Registration Statement or the Prospectus which in the opinion of the Representatives may thereby be made necessary. The term “Underwriter” as used in this Agreement shall include any person substituted under this Section with like effect as if such person had originally been a party to this Agreement.

19

(b) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the Representatives and the Company as provided in subsection (a) above, the aggregate principal amount of the Securities which remains unpurchased does not exceed one-eleventh of the aggregate principal amount of the Securities, then the Company shall have the right to require each non-defaulting Underwriter to purchase the principal amount of Securities which such Underwriter agreed to purchase under this Agreement and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the principal amount of Securities which such Underwriter agreed to purchase under this Agreement) of the Securities of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(c) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the Representatives and the Company as provided in subsection (a) above, the aggregate principal amount of Securities which remains unpurchased exceeds one-eleventh of the aggregate principal amount of the Securities, or if the Company shall not exercise the right described in subsection (b) above to require non-defaulting Underwriters to purchase Securities of a defaulting Underwriter or Underwriters, then this Agreement shall thereupon terminate, without liability on the part of any non-defaulting Underwriter or the Company, except for the expenses to be borne by the Company and the Underwriters as provided in Section 6 hereof and the indemnity and contribution agreements in Section 8 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

10. The respective indemnities, agreements, representations, warranties and other statements of the Company and the several Underwriters, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Underwriter or any controlling person of any Underwriter, or the Company or any officer or director or controlling person of the Company, and shall survive delivery of and payment for the Securities.

11. If this Agreement shall be terminated pursuant to Section 9 hereof, the Company shall not then be under any liability to any Underwriter with respect to the Securities except as provided in Sections 6 and 8 hereof; but, if for any other reason Securities are not delivered by or on behalf of the Company as provided herein, the Company will reimburse the Underwriters through the Representatives for all out-of-pocket expenses approved in writing by the Representatives, including fees and disbursements of counsel, reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of the Securities, but the Company shall then be under no further liability to any Underwriter with respect to the Securities except as provided in Sections 6 and 8 hereof.

12. In all dealings hereunder, the Representatives of the Underwriters shall act on behalf of each of such Underwriters, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Underwriter made or given by such Representatives jointly or by such of the Representatives, if any, as may be designated for such purpose in this Agreement.

20

All statements, requests, notices and agreements hereunder shall be in writing, and if to the Underwriters shall be delivered or sent by mail, overnight courier or facsimile transmission to BofA Securities, Inc., 114 West 47th Street, NY8-114-07-01, New York, New York 10036, Attention: High Grade Transaction Management/Legal, Fax: (212) 901-7881, Email: dg.hg_ua_notices@bofa.com; Mizuho Securities USA LLC, 1271 Avenue of the Americas, New York, New York 10020, Attention: Debt Capital Market, Fax: (212) 205-7812; RBC Capital Markets, LLC, Brookfield Place, 200 Vesey Street, 8th Floor, New York, New York 10281, Attention: DCM Transaction Management/Scott Primrose, Telephone: (212) 618-7706, Email: TMGUS@rbccm.com; and Scotia Capital (USA) Inc., 250 Vesey Street, New York, New York 10281, Attention: Debt Capital Markets/Chief Legal Officer, Email: US.Legal@scotiabank.com and TAG@scotiabank.com; and if to the Company shall be delivered or sent by mail or overnight courier to Sempra, 488 8^th Avenue, San Diego, California 92101, Attention: Secretary, with a copy to the General Counsel; provided, however, that any notice to an Underwriter pursuant to Section 8(c) hereof shall be delivered or sent by mail, overnight courier or facsimile transmission to such Underwriter at its address set forth in its Underwriters’ Questionnaire, or email or facsimile transmission constituting such Questionnaire, which address will be supplied to the Company by the Representatives upon request. Any such statements, requests, notices or agreements shall take effect upon receipt thereof.

In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Underwriters are required to obtain, verify and record information that identifies their respective clients, including the Company, which information may include the name and address of their respective clients, as well as other information that will allow the Underwriters to properly identify their respective clients.

13. This Agreement shall be binding upon, and inure solely to the benefit of, the Underwriters, the Company and, to the extent provided in Sections 8 and 10 hereof, the directors, officers, employees and agents of each Underwriter, the officers, directors and employees of the Company and each person who controls the Company or any Underwriter, and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. No purchaser of any of the Securities from any Underwriter shall be deemed a successor or assign by reason merely of such purchase.

14. The Company acknowledges and agrees that the Underwriters are acting solely in the capacity of an arm’s length contractual counterparty to the Company with respect to the offering of the Securities contemplated hereby (including in connection with determining the terms of the offering) and not as a financial advisor or a fiduciary to, or an agent of, the Company or any other person. The Company agrees that it will not claim that the Underwriters have rendered advisory services of any nature or respect, or owe an agency, fiduciary or similar duty to the Company, in connection with the transactions contemplated hereby or the process leading thereto. Additionally, neither the Representatives nor any other Underwriter is advising the Company or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction. The Company shall consult with its own advisors concerning such

21

matters and shall be responsible for making its own independent investigation and appraisal of the transactions contemplated hereby, and the Underwriters shall have no responsibility or liability to the Company with respect thereto. Any review by the Underwriters of the Company, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Underwriters and shall not be on behalf of the Company, and none of the activities of the Underwriters in connection with the transactions contemplated herein constitutes a recommendation or investment advice by the Underwriters with respect to any entity or natural person.

15. (a) In the event that any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

SEMPRA

6.875% Fixed-to-Fixed Reset Rate Junior Subordinated Notes due 2054

Sempra (formerly known as Sempra Energy), a corporation duly organized and existing under the laws of the State of California (herein called the “Corporation,” which term includes any successor Person under the Indenture hereinafter referred to), for value received, hereby promises to pay to ____________________, or registered assigns, the principal sum of ____________________ Dollars ($____________________) on October 1, 2054 (the “Maturity Date”), and to pay interest thereon from and including March 14, 2024 (the “Original Issue Date”) or from the most recent date to which interest has been paid or duly provided for, semi-annually in arrears on April 1 and October 1 in each year (each, an “Interest Payment Date”), commencing October 1, 2024 (subject to the right of the Corporation to defer the payment of interest, but not beyond the Maturity Date, in accordance with the provisions set forth below), and on the Maturity Date (i) from and including the Original Issue Date to but excluding October 1, 2029 (the “First Reset Date”), at the rate of 6.875% per annum and (ii) from and including the First Reset Date, during each Reset Period (as defined below) at a rate per annum equal to the Five-year U.S. Treasury Rate (as defined below) as of the most recent Reset Interest Determination Date (as defined below) plus a spread of 2.789%, to be reset on each Reset Date (as defined below), until the principal hereof is paid or made available for payment, provided that any principal hereof or (to the extent that the payment of such interest shall be legally enforceable) premium, if any, or interest hereon which is not paid when due shall bear interest at the then-applicable interest rate on the Securities (as defined on the reverse hereof) of this series (as reset from time to time in accordance with the terms of the Securities of this series) from the respective dates such amounts are due until they are paid or made available for payment, and such interest shall be payable on demand. Interest on this Security shall be calculated on the basis of a 360-day year consisting of twelve 30-day months.

The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in the Indenture, be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest, which shall be the March 15 or September 15 (whether or not a Business Day (as defined in the Indenture)), as the case may be, immediately preceding such Interest Payment Date. Any such interest not so punctually paid or duly provided for on any Interest Payment Date will forthwith cease to be payable to the Holder on such Regular Record Date by virtue of having been such Holder and may either be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee (as defined on the reverse hereof), notice whereof shall be given to Holders of Securities of this series not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities of this series may be listed, and upon such notice as may be required by such exchange, all as more fully provided in said Indenture.

Annex II-2

The applicable interest rate for each Reset Period will be determined by the Calculation Agent (as defined below), as of the applicable Reset Interest Determination Date, in accordance with the following provisions:

“Five-year U.S. Treasury Rate” means, as of any Reset Interest Determination Date, (i) an interest rate (expressed as a decimal) determined to be the per annum rate equal to the arithmetic mean of the yields to maturity for U.S. Treasury securities adjusted to constant maturity with a maturity of five years from the next Reset Date and trading in the public securities markets, for the five consecutive business days immediately prior to the respective Reset Interest Determination Date as published in the most recent H.15, or (ii) if there is no such published U.S. Treasury security with a maturity of five years from the next Reset Date and trading in the public securities markets, then the rate will be determined by interpolation between the arithmetic mean of the yields to maturity for each of the two series of U.S. Treasury securities adjusted to constant maturity trading in the public securities markets, (A) one maturing as close as possible to, but earlier than, the Reset Date following the next succeeding Reset Interest Determination Date, and (B) the other maturing as close as possible to, but later than, the Reset Date following the next succeeding Reset Interest Determination Date, in each case for the five consecutive business days immediately prior to the respective Reset Interest Determination Date as published in the most recent H.15. If the Five-year U.S. Treasury Rate cannot be determined pursuant to the methods described in clause (i) or (ii) above, then the Five-year U.S. Treasury Rate will be the same interest rate determined for the prior Reset Interest Determination Date or, if the Five-year U.S. Treasury Rate cannot be so determined as of the Reset Interest Determination Date preceding the First Reset Date, then the interest rate applicable for the Reset Period beginning on and including the First Reset Date will be deemed to be 6.875% per annum, which is the same interest rate as in effect from and including the Original Issue Date to, but excluding, the First Reset Date.

“H.15” means the statistical release designated as such, or any successor publication, published by the Board of Governors of the U.S. Federal Reserve System (or any successor thereto).

The “most recent H.15” means the H.15 published closest in time but prior to the close of business on the second business day (as defined below) prior to the applicable Reset Date.

“Reset Date” means the First Reset Date and October 1 of every fifth year after 2029.

“Reset Interest Determination Date” means, in respect of any Reset Period, the day falling two business days prior to the first day of such Reset Period.

“Reset Period” means the period from and including the First Reset Date to, but excluding, the next following Reset Date and thereafter each period from and including a Reset Date to, but excluding, the next following Reset Date.

The term “business day” means, unless otherwise expressly stated, any day other than (i) a Saturday or Sunday or (ii) a day on which banking institutions in The City of New York are authorized or obligated by law or executive order to remain closed.

“Calculation Agent” means, at any time, the entity appointed by the Corporation and serving as such agent with respect to the Securities of this series at such time. Unless the Corporation has validly called all of the outstanding Securities of this series for redemption on a Redemption Date occurring prior to the First Reset Date, the Corporation will appoint a Calculation Agent for the Securities of this series prior to the Reset Interest Determination Date immediately preceding the First Reset Date; provided that, if the Corporation has called all of the outstanding Securities of this series for redemption on a Redemption Date occurring prior to the First Reset Date but the Corporation does not redeem all of the outstanding Securities of this series on such Redemption Date, the Corporation will appoint a Calculation Agent for the Securities of this series as promptly as practicable after such proposed Redemption Date. The Corporation may terminate any such appointment and may appoint a successor Calculation Agent at any time and from time to time (so long as there shall always be a Calculation Agent in respect of the Securities of this series when so required). The Corporation may appoint itself or an Affiliate of the Corporation as Calculation Agent.

Annex II-3

As provided above, the applicable interest rate for each Reset Period will be determined by the Calculation Agent as of the applicable Reset Interest Determination Date. Promptly upon such determination, the Calculation Agent will notify the Corporation of the interest rate for the Reset Period and the Corporation will promptly notify, or cause the Calculation Agent to promptly notify, the Trustee and each Paying Agent for the Securities of this series of such interest rate. The Calculation Agent’s determination of any interest rate, and its calculation of the amount of interest for any Interest Payment Period (as defined below) beginning on or after the First Reset Date, will be on file at the Corporation’s principal offices, will be made available to any Holder or beneficial owner of the Securities of this series upon request and will be final and binding in the absence of manifest error.

The Trustee shall not be responsible or liable for the actions or omissions of the Calculation Agent, or any failure or delay in the performance of the Calculation Agent’s duties or obligations, nor shall the Trustee be under any obligation to oversee or monitor the Calculation Agent’s performance; and the Trustee shall be entitled to rely conclusively upon any determination made, and any instruction, notice, officer certificate, or other instrument or information provided, by the Calculation Agent, without independent verification, investigation or inquiry of any kind.

The Trustee shall be under no duty to succeed to, assume or otherwise perform any of the duties of the Calculation Agent, or to appoint a successor or replacement in the event of the Calculation Agent’s resignation or removal, or to remove and replace the Calculation Agent in the event of a default, breach or failure of performance on the part of the Calculation Agent with respect to its duties and obligations under the terms of the governing documents.

So long as no Event of Default with respect to the Securities of this series has occurred and is continuing, the Corporation may, at its option, defer interest payments on the Securities of this series, from time to time, for one or more deferral periods of up to 20 consecutive Interest Payment Periods each (each such deferral period, commencing on the Interest Payment Date on which the first such deferred interest payment otherwise would have been made, an “Optional Deferral Period”), except that no such Optional Deferral Period may extend beyond the Maturity Date or end on a day other than the day immediately preceding an Interest Payment Date. During any Optional Deferral Period, interest on the Securities of this series will continue to accrue at the then-applicable interest rate on the Securities of this series (as reset from time to time on any Reset Date occurring during such Optional Deferral Period in accordance with the terms of the Securities of this series). In addition, during any Optional Deferral Period interest on the deferred interest (“compound interest”) will accrue at the then-applicable interest rate on the Securities of this series (as reset from time to time on any Reset Date occurring during such Optional Deferral Period in accordance with the terms of the Securities of this series), compounded semi-annually, to the extent permitted by applicable law. No interest will be due or payable on the Securities of this series during an Optional Deferral Period, except upon a redemption of any Securities of this series on any Redemption Date during such Optional Deferral Period (in which case all accrued and unpaid interest (including, to the extent permitted by applicable law, any compound interest) on the Securities of this series to be redeemed to, but excluding, such Redemption Date will be due and payable on such Redemption Date), or unless the principal of and interest on the Securities of this series shall have been declared due and payable as the result of an Event of Default with respect to the Securities of this series (in which case all accrued and unpaid interest on the Securities of this series, including, to the extent permitted by applicable law, any compound interest on the Securities of this series, shall become due and payable). All references in the Securities of this series and, insofar as relates to the Securities of this series, the Indenture to “interest” on the Securities of this series shall be deemed to include any such deferred interest and, to the extent permitted by applicable law, any compound interest, unless otherwise expressly stated or the context otherwise requires.

Before the end of any Optional Deferral Period that is shorter than 20 consecutive Interest Payment Periods, the Corporation may elect, at its option, to extend such Optional Deferral Period, so long as the entire Optional Deferral Period does not exceed 20 consecutive Interest Payment Periods or extend beyond the Maturity Date. The Corporation may also elect, at its option, to shorten the length of any Optional Deferral Period. No Optional Deferral Period (including as extended or shortened) may end on a day other than the day immediately preceding an Interest Payment Date. At the end of any Optional Deferral Period, if all amounts then due on the Securities of this series, including all accrued and unpaid interest thereon (including, without limitation and to the extent permitted by applicable law, any compound interest), shall have been paid in full, the Corporation may elect to begin a new Optional Deferral Period; provided, however, that, without limitation of the foregoing, the Corporation may not begin a new Optional Deferral Period unless the Corporation has paid all accrued and unpaid interest on the Securities of this series (including, without limitation and to the extent permitted by applicable law, any compound interest) from any previous Optional Deferral Periods.

Annex II-4

IN WITNESS WHEREOF, the Corporation has caused this instrument to be duly executed.

Annex II-7

(REVERSE OF SECURITY)

This Security is one of a duly authorized issue of debt securities of the Corporation (herein called the “Securities” or the “Securities of this series”), issued and to be issued in one or more series under an Indenture, dated as of June 26, 2019 (herein called the “Indenture,” which term shall have the meaning assigned to it in such instrument), between the Corporation and U.S. Bank Trust Company, National Association (herein called the “Trustee,” which term includes any successor trustee under the Indenture), as successor in interest to U.S. Bank National Association, and reference is hereby made to the Indenture for a statement of the respective rights, limitation of rights, duties and immunities thereunder of the Corporation, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof.

The Corporation may at its option redeem the Securities of this series, in whole or from time to time in part, (i) on any day in the period commencing on the date falling 90 days prior to the First Reset Date and ending on and including the First Reset Date and (ii) after the First Reset Date, on any Interest Payment Date, at a Redemption Price in cash equal to 100% of the principal amount of the Securities of this series to be redeemed, plus (subject to the provisions set forth below regarding the payment of installments of interest on Securities of this series that are due and payable on any Interest Payment Date falling on or prior to a Redemption Date) accrued and unpaid interest on the Securities of this series to be redeemed to, but excluding, the Redemption Date.

The Corporation may at its option redeem the Securities of this series, in whole but not in part, at any time following the occurrence and during the continuance of a Tax Event (as defined below) at a Redemption Price in cash equal to 100% of the principal amount of the Securities of this series, plus (subject to the provisions set forth below regarding the payment of installments of interest on Securities of this series that are due and payable on any Interest Payment Date falling on or prior to a Redemption Date) accrued and unpaid interest on the Securities of this series to, but excluding, the Redemption Date.

A “Tax Event” means that the Corporation has received an opinion of counsel experienced in such matters to the effect that, as a result of:

which amendment, clarification or change is effective or the administrative action is taken or judicial decision, interpretation or pronouncement is issued or threatened challenge is asserted or becomes publicly-known after March 11, 2024, there is more than an insubstantial risk that interest payable by the Corporation on the Securities of this series is not deductible, or within 90 days would not be deductible, in whole or in part, by the Corporation for United States federal income tax purposes.

Annex II-8

The Corporation may at its option redeem the Securities of this series, in whole but not in part, at any time following the occurrence and during the continuance of a Rating Agency Event (as defined below) at a Redemption Price in cash equal to 102% of the principal amount of the Securities of this series, plus (subject to the provisions set forth below regarding the payment of installments of interest on Securities of this series that are due and payable on any Interest Payment Date falling on or prior to a Redemption Date) accrued and unpaid interest on the Securities of this series to, but excluding, the Redemption Date.

“Rating Agency Event” means, as of any date, a change, clarification or amendment in the methodology published by any nationally recognized statistical rating organization within the meaning of Section 3(a)(62) of the Securities Exchange Act of 1934, as amended (or any successor provision thereto), that then publishes a rating for the Corporation (together with any successor thereto, a “rating agency”) in assigning equity credit to securities such as the Securities of this series, (a) as such methodology was in effect on March 11, 2024, in the case of any rating agency that published a rating for the Corporation as of March 11, 2024, or (b) as such methodology was in effect on the date such rating agency first published a rating for the Corporation, in the case of any rating agency that first publishes a rating for the Corporation after March 11, 2024 (in the case of either clause (a) or (b), the “current methodology”), that results in (i) any shortening of the length of time for which a particular level of equity credit pertaining to the Securities of this series by such rating agency would have been in effect had the current methodology not been changed or (ii) a lower equity credit (including up to a lesser amount) being assigned by such rating agency to the Securities of this series as of the date of such change, clarification or amendment than the equity credit that would have been assigned to the Securities of this series by such rating agency had the current methodology not been changed.

Notwithstanding any statement to the contrary set forth above, installments of interest on the Securities of this series that are due and payable on any Interest Payment Date falling on or prior to a Redemption Date for the Securities of this series will be payable on that Interest Payment Date to the Holders of such Securities as of the close of business on the Regular Record Date immediately preceding such Interest Payment Date, according to the terms of the Securities of this series and the Indenture, except that, if a Redemption Date for any Securities of this series falls on any day during an Optional Deferral Period, accrued and unpaid interest (including, to the extent permitted by applicable law, any compound interest) on such Securities of this series will be paid on such Redemption Date to the Persons entitled to receive the Redemption Price of such Securities of this series. For the avoidance of doubt, the Interest Payment Date falling immediately after the last day of an Optional Deferral Period shall not be deemed to fall on a day during such Optional Deferral Period.

The Corporation will mail or cause to be mailed notice of any redemption at least 30 days but not more than 60 days before the Redemption Date to each Holder of the Securities of this series to be redeemed. Once notice of redemption is mailed, the Securities of this series called for redemption will become due and payable on the Redemption Date at the applicable Redemption Price, plus, subject to the terms described in the immediately preceding paragraph, accrued and unpaid interest to, but excluding, the Redemption Date, and will be paid upon surrender thereof for redemption, unless (a) the notice of redemption provides that such redemption shall be subject to the condition described in the next succeeding paragraph and (b) such redemption shall have been canceled in accordance with the provisions of the next succeeding paragraph because such condition shall not have been satisfied. If only part of a Security of this series is redeemed, the Trustee will issue in the name of the Holder hereof and deliver to such Holder a new Security of this series in a principal amount equal to the unredeemed portion of the principal of the Security of this series surrendered for redemption. If the Corporation elects to redeem all or a portion of the Securities of this series, then, unless otherwise provided in the notice of redemption as described in the next succeeding paragraph, the redemption will not be conditional upon receipt by the Paying Agent or the Trustee of monies sufficient to pay the Redemption Price.

If, at the time a notice of redemption is given, (i) the Corporation has not effected satisfaction and discharge or Defeasance of the Securities of this series pursuant to Section 401 or Section 1302, respectively, of the Indenture and (ii) such notice of redemption is not being given in connection with or in order to effect satisfaction and discharge or Defeasance of the Securities of this series, then, if the notice of redemption so provides and at the Corporation’s option, the redemption may be subject to the condition that the Trustee shall have received, on or before the applicable Redemption Date, monies in an amount sufficient to pay the Redemption Price and accrued and unpaid interest on the

Annex II-9

Securities of this series called for redemption to, but excluding, the Redemption Date. If monies in such amount are not received by the Trustee on or before such Redemption Date, such notice of redemption shall be automatically canceled and of no force or effect, such proposed redemption shall be automatically canceled and the Corporation shall not be required to redeem the Securities of this series called for redemption on such Redemption Date. In the event that a redemption is canceled, the Corporation will, not later than the business day immediately following the proposed Redemption Date, deliver, or cause to be delivered, notice of such cancellation to the Holders of the Securities of this series called for redemption (which notice will also indicate that any Securities of this series or portions thereof surrendered for redemption shall be returned to the applicable Holders), and the Corporation will direct the Trustee to, and the Trustee will, promptly return any Securities of this series or portions thereof that have been surrendered for redemption to the applicable Holders.

Unless the Corporation defaults in payment of the Redemption Price or the proposed redemption is canceled in accordance with the provisions set forth in the immediately preceding paragraph, on and after the Redemption Date interest will cease to accrue on the Securities of this series or portions thereof called for redemption.

If less than all of the Securities of this series are to be redeemed on any Redemption Date, the particular Securities of this series (or portions thereof) to be redeemed shall be selected by such method as the Trustee shall deem fair and appropriate or, in the case of Securities of this series in book-entry form represented by one or more Global Securities, by such method of selection as may be required or permitted by the Depositary for such Global Securities.

The Indenture contains provisions for Defeasance at any time of the entire indebtedness of the Securities of this series upon compliance with certain conditions set forth in the Indenture.

If an Event of Default with respect to the Securities of this series (other than an Event of Default of the type set forth in clause (4) of Section 501 of the Indenture with respect to the Securities of this series) shall occur and be continuing, the principal of and accrued and unpaid interest, if any (including, without limitation, any deferred interest and, to the extent permitted by applicable law, any compound interest), on the Securities of this series may be declared due and payable immediately in the manner and with the effect provided in the Indenture. Neither the Trustee nor the Holders of the Securities of this series shall be entitled to declare the principal of or accrued and unpaid interest on the Securities of this series to be immediately due and payable by reason of the occurrence and continuation of an Event of Default specified in clause (4) of Section 501 of the Indenture applicable to the Securities of this series, and any notice of declaration of acceleration based on such an Event of Default shall be null and void with respect to the Securities of this series; provided that, notwithstanding the foregoing, so long as an Event of Default specified in clause (4) of Section 501 of the Indenture shall have occurred and shall be continuing with respect to the Securities of this series, the Trustee and the Holders of the Securities of this series may exercise the other rights and remedies available under the Indenture in connection with such Event of Default, as well as such other rights and remedies as may be available under applicable law or otherwise.

The indebtedness represented by the Securities of this series is, to the extent and in a manner set forth in the Indenture, expressly subordinated in right of payment to the prior payment of all existing and future Senior Indebtedness (as defined in or pursuant to the Indenture with respect to the Securities of this series) and this Security is issued subject to such provisions, and each Holder of this Security, by acceptance thereof, shall be deemed to have agreed to and to be bound by such provisions and to authorize and direct the Trustee in his, her or its behalf to take such action as may be necessary or appropriate to effectuate such subordination as provided in the Indenture and to appoint the Trustee his, her or its attorney-in-fact, as the case may be, for any and all such purposes. For purposes of the Indenture and anything therein to the contrary notwithstanding, the Securities of this series shall rank equally in right of payment with the Other Junior Subordinated Notes (as defined below), the Other Junior Subordinated Notes shall not constitute Senior Indebtedness with respect to the Securities of this series, and the Securities of this series shall not constitute Senior Indebtedness with respect to the Other Junior Subordinated Notes. “Other Junior Subordinated Notes” means the Corporation’s 4.125% Fixed-to-Fixed Reset Rate Junior Subordinated Notes due 2052 and 5.750% Junior Subordinated Notes due 2079, each of which constitute a separate series of the Corporation’s debt securities under the Indenture and were originally issued on November 19, 2021 and June 26, 2019, respectively, together with any additional debt securities of the same series which may in the future be issued under the Indenture upon any re-opening of such series.

Annex II-10

The Corporation agrees that the Corporation, and each Holder (and beneficial owner) of Securities of this series shall, by accepting any Securities of this series (or a beneficial interest therein), be deemed to have agreed that such Holder (or beneficial owner) intends that the Securities of this series constitute indebtedness of the Corporation, and will treat the Securities of this series as indebtedness of the Corporation, for United States federal, state and local tax purposes.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Corporation and the rights of the Holders of the Securities of each series affected under the Indenture at any time by the Corporation and the Trustee with the consent of the Holders of a majority in principal amount of the Securities of each series at the time Outstanding affected thereby. The Indenture contains provisions permitting the Holders of not less than a majority in principal amount of the Securities of any series at the time Outstanding with respect to which a default under the Indenture shall have occurred and be continuing, on behalf of the Holders of all Securities of such series, to waive, with certain exceptions, such past default with respect to such series and its consequences. The Indenture also permits the Holders of not less than a majority in principal amount of the Securities of any series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Corporation with certain provisions of the Indenture. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 33% in principal amount of the Securities of this series at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee, such Holder or Holders shall have offered the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee, for 60 days after its receipt of such notice, request and offer of indemnity, shall not have received from the Holders of a majority in principal amount of Securities of this series at the time Outstanding a direction inconsistent with such request, and the Trustee shall have failed to institute any such proceeding for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Corporation, which is absolute and unconditional, to pay the principal of and premium, if any, and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Corporation in any place where the principal of and any premium and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Corporation and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

The Securities of this series are issuable only in registered form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.

No service charge shall be made for any such registration of transfer or exchange, but the Corporation may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith, subject to certain exceptions set forth in the Indenture.

Annex II-11

Prior to due presentment of this Security for registration of transfer, the Corporation, the Trustee and any agent of the Corporation or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Corporation, the Trustee nor any such agent shall be affected by notice to the contrary.

This Security shall be governed by and construed in accordance with the laws of the State of New York, without regard to conflict of law principles thereof.

All terms used in this Security which are defined in the Indenture and not defined herein shall have the meanings assigned to them in the Indenture.

We have acted as special counsel to Sempra, a California corporation (the “Company”), in connection with the Company’s issuance of 6.875% Fixed-to-Fixed Reset Rate Junior Subordinated Notes due 2054 (the “Notes”) under a Subordinated Indenture, dated as of June 26, 2019, between the Company and U.S. Bank Trust Company, National Association, as successor trustee to U.S. Bank National Association (the “Trustee”), and an officers’ certificate, dated March 14, 2024, setting forth the terms of the Notes (together, the “Indenture”), and pursuant to a registration statement on Form S-3 under the Securities Act of 1933, as amended (the “Act”), filed with the Securities and Exchange Commission (the “Commission”) on May 6, 2023 (Registration No. 333-272237) (as so filed the “Registration Statement”), and an underwriting agreement, dated March 11, 2024, between the underwriters named therein and the Company.

This opinion is being furnished in connection with the requirements of Item 601(b)(5) of Regulation S-K under the Act, and no opinion is expressed herein as to any matter pertaining to the contents of the Registration Statement or related prospectus, other than as expressly stated herein with respect to the issue of the Notes.

We are opining as to the internal laws of the State of New York and the general corporation law of the State of California, and we express no opinion with respect to the applicability to the opinion expressed herein, or the effect thereon, of the laws of any other jurisdiction or, in the case of California, any other laws, or as to any matters of municipal law or the laws of any local agencies within any state.

Subject to the foregoing and the other matters set forth herein, it is our opinion that, as of the date hereof, the Notes have been duly authorized by all necessary corporate action of the Company and are the legally valid and binding obligations of the Company, enforceable against the Company in accordance with their terms.

Our opinion is subject to: (i) the effects of bankruptcy, insolvency, reorganization, preference, fraudulent transfer, moratorium or other similar laws relating to or affecting the rights or remedies of creditors; (ii) the effects of general principles of equity, whether considered in a proceeding in equity or at law (including the possible unavailability of specific performance or injunctive relief), concepts of materiality, reasonableness, good faith, fair dealing and the discretion of the court before which a proceeding is brought; (iii) the invalidity under certain circumstances under law or court decisions of provisions for the indemnification or exculpation of, or contribution to, a party with respect to a liability where such indemnification, exculpation or contribution is contrary to public policy; and (iv) we express no opinion with respect to (a) consents to, or restrictions upon, governing law, jurisdiction, venue, service of process, arbitration, remedies or judicial relief, (b) advance waivers of claims, defenses, rights granted by law, or notice, opportunity for hearing, evidentiary requirements, statutes of limitation, trial by jury or at law, or other procedural rights, (c) waivers of rights or defenses contained in Section 515 of the Indenture, and waivers of broadly or vaguely stated rights, (d) provisions for exclusivity, election or cumulation of rights or remedies, (e) provisions authorizing or validating conclusive or discretionary determinations, (f) provisions for the payment of attorneys’ fees where such payment is contrary to law or public policy and we call to your attention the provisions of Sections 1717 and 1717.5 of the California Civil Code, which limit and create obligations for the payment of attorneys’ fees, (g) provisions prohibiting, restricting, or requiring consent to assignment or transfer of any agreement, right or property, or the effect thereon of California Civil Code Section 711, (h) provisions for liquidated damages, default interest, late charges, monetary penalties, prepayment or make-whole premiums or other economic remedies to the extent such provisions are deemed to constitute a penalty, (i) provisions permitting, upon acceleration of any indebtedness (including the Notes), collection of that portion of the stated principal amount thereof which might be determined to constitute unearned interest thereon, and (j) the severability, if invalid, of provisions to the foregoing effect.

With your consent, except to the extent we have expressly opined as to such matters with respect to the Company herein we have assumed (a) that the Indenture and the Notes (collectively, the “Documents”) have been duly authorized, executed and delivered by the parties thereto, (b) that the Documents constitute legally valid and binding obligations of the parties thereto, enforceable against each of them in accordance with their respective terms, and (c) that the status of the Documents as legally valid and binding obligations of the parties is not affected by any (i) breaches of, or defaults under, agreements or instruments, (ii) violations of statutes, rules, regulations or court or governmental orders, or (iii) failures to obtain required consents, approvals or authorizations from, or make required registrations, declarations or filings with, governmental authorities.
