PROSPECTUS SUPPLEMENT

(To Prospectus dated May 26, 2023)

$3,000,000,000

Common Stock

We have entered into an ATM Equity Offering Sales Agreement (the “sales agreement”), with Barclays Capital Inc., BofA Securities, Inc., Citigroup Global Markets Inc., Goldman Sachs & Co. LLC, J.P. Morgan Securities LLC, Mizuho Securities USA LLC, Morgan Stanley & Co. LLC, MUFG Securities Americas Inc., RBC Capital Markets, LLC, Scotia Capital (USA) Inc., and Wells Fargo Securities, LLC (the “agents”), and the forward purchasers (as defined below), relating to the offering of shares of our common stock having an aggregate gross sales price of up to $3,000,000,000.

In accordance with the terms of the sales agreement, shares of our common stock may be offered and sold from time to time to or through the agents, as our sales agents or, if applicable, as forward sellers. Sales of shares of our common stock, if any, will be made in negotiated transactions, including block trades, or transactions that are deemed to be “at the market” offerings as defined in Rule 415 under the Securities Act of 1933, as amended (the “Securities Act”), by means of ordinary brokers’ transactions at market prices prevailing at the time of sale, including sales made directly on the New York Stock Exchange (the “NYSE”), sales made to or through a market maker and sales made through other securities exchanges or electronic communications networks or by any other method permitted by applicable law as otherwise agreed between the applicable agent and us.

The sales agreement contemplates that, in addition to the issuance and sale by us of shares of our common stock to or through the agents, we may enter into separate forward sale agreements with each of Barclays Bank PLC, Bank of America, N.A., Citibank, N.A., Goldman Sachs & Co. LLC, JPMorgan Chase Bank, National Association, Mizuho Markets Americas LLC, Morgan Stanley & Co. LLC, MUFG Securities EMEA plc, Royal Bank of Canada, The Bank of Nova Scotia and Wells Fargo Bank, National Association, or one of their respective affiliates (the “forward purchasers”). If we enter into a forward sale agreement with any forward purchaser, we expect that such forward purchaser (or its affiliate) will attempt to borrow from third parties and sell, through the relevant agent, acting as sales agent for such forward purchaser, shares of our common stock to hedge such forward purchaser’s exposure under such forward sale agreement. We refer to an agent, when acting as sales agent for the relevant forward purchaser, as, individually, a “forward seller” and, collectively, the “forward sellers.” Unless otherwise expressly stated or the context otherwise requires, references herein to the “related” or “relevant” forward purchaser mean, with respect to any agent, the affiliate of such agent that is acting as forward purchaser or, if applicable, such agent acting in its capacity as forward purchaser. We will not receive any proceeds from any sale of shares of our common stock borrowed by a forward purchaser (or its affiliate) and sold through a forward seller.

We currently expect to fully physically settle each forward sale agreement, if any, with the relevant forward purchaser on one or more dates specified by us on or prior to the maturity date of such forward sale agreement, in which case we expect to receive aggregate net cash proceeds at settlement equal to the number of shares specified in such forward sale agreement multiplied by the relevant initial forward price per share (subject to adjustment as described in this prospectus supplement). However, subject to certain exceptions, we may also elect, in our sole discretion, to cash settle or net share settle all or any portion of our obligations under any forward sale agreement, in which case we may not receive any proceeds (in the case of cash settlement) or will not receive any proceeds (in the case of net share settlement), and we may owe cash (in the case of cash settlement) or shares of our common stock (in the case of net share settlement) to the relevant forward purchaser. See “Plan of Distribution (Conflicts of Interest)” in this prospectus supplement.

No agent is required to sell any specific number or dollar amount of shares of our common stock, but each agent has agreed to use its commercially reasonable efforts, consistent with its normal trading and sales practices and applicable law and regulations, as our sales agent or as forward seller, and subject to the terms and conditions of the sales agreement and, in the case of shares offered through such agent as forward seller, the relevant forward sale agreement, to sell shares of our common stock, on mutually agreed terms between the agent and us. Shares of our common stock offered and sold through the agents, as our sales agents or as forward sellers, pursuant to this prospectus supplement and the accompanying prospectus, will be offered and sold through only one agent on any given day.

Each agent will receive from us a commission that will not exceed, but may be lower than, 1.0% of the gross sales price of all shares of our common stock sold through it as our sales agent under the sales agreement. In connection with each forward sale agreement, the applicable agent, as forward seller, will receive a commission, in the form of a reduction to the initial forward price under the related forward sale agreement, at a mutually agreed rate that will not (except as provided below) exceed, but may be lower than, 1.0% of the volume-weighted average of the gross sales price per share of all of the borrowed shares of our common stock sold through such agent, as forward seller, during the applicable forward selling period for such shares (subject to certain possible adjustments to such gross sales price for daily accruals and any quarterly dividends having an “ex-dividend” date during such forward selling period).

Under the terms of the sales agreement, we may also sell shares of our common stock to one or more of the agents as principal, at a price per share to be agreed upon at the time of sale. If we sell shares of our common stock to one or more of the agents as principal, we will enter into a separate terms agreement with such agent or agents, as the case may be, and we will describe the terms of the offering of those shares of our common stock in a separate prospectus supplement or pricing supplement. In any such sale to an agent as principal, we may agree to pay the applicable agent an underwriting discount or commission that may exceed 1.0% of the gross sales price per share sold to such agent, as principal.

In connection with the sale of shares of our common stock, each agent may, and in connection with sales of shares of our common stock purchased by an agent as principal will, be deemed to be an “underwriter” within the meaning of the Securities Act, and the compensation paid to the agent may, or will, as applicable, be deemed to be underwriting commissions.

Our common stock is listed on the NYSE under the symbol “SRE.” On November 5, 2024, the last reported sale price of our common stock on the NYSE was $82.25 per share.

Investing in our common stock involves risks. See the “Risk Factors” section on page S-5 of this prospectus supplement.

Neither the U.S. Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus supplement or the accompanying prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

RISK FACTORS

Investment in our common stock involves risks. You should carefully consider the risks described below and the risk factors and other cautionary language incorporated into this prospectus supplement and the accompanying prospectus by reference to our most recent Annual Report on Form 10-K and our subsequent Quarterly Reports on Form 10-Q and any Current Reports on Form 8-K filed (and not furnished) by us with the SEC subsequent to the last day of the fiscal year covered by our most recent Annual Report on Form 10-K and all other information contained or incorporated by reference in this prospectus supplement and the accompanying prospectus, as updated by our subsequent filings under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), that are incorporated by reference in this prospectus supplement and the accompanying prospectus, as well as any free writing prospectus we may provide you in connection with this offering, before acquiring any shares of our common stock. There may be other risks and uncertainties not known to us or that we deem immaterial that also could impair our business operations, financial results and the value of our common stock. The occurrence of any of these risks could have a material adverse effect on our results of operations, financial condition, cash flows and/or prospects and might cause you to lose all or part of your investment in our common stock. See also “Forward-Looking Statements and Market Data.” In that regard, unless otherwise expressly stated or the context otherwise requires, references to our common stock appearing under this caption “Risk Factors” or the caption “Risk Factors” in our most recent Annual Report on Form 10-K and our subsequent Quarterly Reports on Form 10-Q include the common stock offered hereby.

Risks Related to the Forward Sale Agreements

The following risk factor applies to the forward sale agreements we may enter into in connection with this offering.

Settlement provisions contained in the forward sale agreements subject us to certain risks.

Each forward purchaser will have the right to accelerate its forward sale agreement (or, in certain cases, the portion thereof that the forward purchaser determines is affected by the relevant event) and require us to physically settle the forward sale agreement on a date specified by the forward purchaser if, subject to a prior notice requirement:

S-5

A forward purchaser’s decision to exercise its right to accelerate all or a portion of the settlement of its forward sale agreement and to require us to physically settle the relevant shares will be made irrespective of our interests, including our need for capital. In such cases, we could be required to issue and deliver shares of our common stock under the terms of the physical settlement irrespective of our capital needs, which would result in dilution to our earnings per common share and may adversely affect the market price of our common stock, Series C preferred stock and any other series of preferred stock we may issue in the future.

The forward price that we expect to receive upon physical settlement of a forward sale agreement will be subject to adjustment on a daily basis based on a floating interest rate factor. If the specified daily rate is less than the applicable spread on any day, this will result in a daily reduction of the forward price. In addition, the forward price will be subject to decrease on certain dates specified in the relevant forward sale agreement by the amount per share of quarterly dividends we expect to declare on our common stock during the term of such forward sale agreement.

We will generally have the right, in lieu of physical settlement of any forward sale agreement, to elect cash or net share settlement in respect of any or all of the shares of our common stock subject to such forward sale agreement. If we elect to cash or net share settle all or any part of any forward sale agreement, we would expect to issue a substantially lower number of shares than if we settled by physical delivery, but would not receive the cash for the shares that would have otherwise been issued if we settled the entire forward sale agreement by physical delivery and, as a result, would not derive the same credit metrics benefits.

If the price of our common stock at which these purchases are made by such forward purchaser (or its affiliate) exceeds the applicable forward price, we will pay such forward purchaser an amount in cash equal to such difference (if we elect to cash settle) or we will deliver to such forward purchaser a number of shares of our common stock having a market value equal to such difference (if we elect to net share settle). Any such difference could be significant and could require us to pay a significant amount of cash or deliver a significant number of shares of our common stock to such forward purchaser.

The purchase of shares of our common stock by a forward purchaser or its affiliate to unwind the forward purchaser’s hedge position could cause the price of our common stock to increase above the price that would have prevailed in the absence of those purchases (or prevent a decrease in such price), thereby increasing the amount of cash (in the case of cash settlement) or the number of shares (in the case of net share settlement) that we would owe such forward purchaser upon settlement of the applicable forward sale agreement or decreasing the amount of cash (in the case of cash settlement) or the number of shares (in the case of net share settlement) that such forward purchaser would owe us upon settlement of the applicable forward sale agreement.

See “Plan of Distribution (Conflicts of Interest)” for more information about the terms of the forward sale agreements.

S-6

USE OF PROCEEDS

We intend to use a substantial portion of the net proceeds we receive from the issuance and sale by us of any shares of our common stock to or through the agents and any net proceeds we receive pursuant to the settlement of any forward sale agreements with the relevant forward purchasers for working capital and other general corporate purposes, including to partly finance anticipated increases to our long-term capital plan and to repay outstanding commercial paper and potentially other indebtedness. As of November 5, 2024, Sempra had approximately $624 million of commercial paper outstanding (excluding Sempra’s consolidated entities and any commercial paper outstanding under their respective programs), bearing interest at rates of 5.59% per annum or less and maturing at various dates through November 20, 2024. Depending on when we receive any net proceeds from this offering, including pursuant to the settlement of any forward sale agreement, the commercial paper that we repay with such net proceeds may be subsequent issuances of commercial paper.

Our intended uses of any net proceeds from this offering, including pursuant to the settlement of any forward sale agreement, as described above represent only our current expectations based on present plans, estimates and assumptions, and we cannot predict with any certainty all of the particular uses of such net proceeds or the amounts and timing of our actual expenditures.

Pending application of any net proceeds from this offering, including pursuant to the settlement of any forward sale agreement, for the foregoing intended purposes, we expect to invest such net proceeds in various instruments which may include, but would not be limited to, short- and intermediate-term, interest-bearing obligations, including bank deposits and certificates of deposit with financial institutions having investment-grade ratings, U.S. government obligations or money market funds primarily invested in securities issued by the U.S. government or its agencies.

We currently expect to fully physically settle each forward sale agreement, if any, with the relevant forward purchaser on one or more dates specified by us on or prior to the maturity date of such forward sale agreement, in which case we expect to receive aggregate net cash proceeds at settlement equal to the number of shares specified in such forward sale agreement multiplied by the relevant initial forward price per share (subject to adjustment as described in “Plan of Distribution (Conflicts of Interest)” in this prospectus supplement). However, subject to certain exceptions, we may also elect, in our sole discretion, to cash settle or net share settle all or any portion of our obligations under any forward sale agreement, in which case we may not receive any proceeds (in the case of cash settlement) or will not receive any proceeds (in the case of net share settlement), and we may owe cash (in the case of cash settlement) or shares of our common stock (in the case of net share settlement) to the relevant forward purchaser.

As described above, we may use any net proceeds from this offering, including pursuant to the settlement of any forward sale agreement, to repay commercial paper and potentially other indebtedness. One or more of the agents participating in this offering and/or their affiliates may hold positions in our commercial paper or other indebtedness of ours, three of the agents act as dealers under our commercial paper program, and affiliates of all of the agents are lenders under our credit facilities. To the extent that net proceeds from this offering, including pursuant to the settlement of any forward sale agreement, are applied to repay any of our outstanding indebtedness (including commercial paper, bank loans or other indebtedness) held by any of the agents or their affiliates, they will receive proceeds from this offering through the repayment of that indebtedness. See “Plan of Distribution (Conflicts of Interest)—Other Relationships” and “Plan of Distribution (Conflicts of Interest)—Conflicts of Interest.”

If we enter into a forward sale agreement with any forward purchaser, we expect that such forward purchaser (or its affiliate) will attempt to borrow from third parties and sell, through the relevant agent, acting as sales agent for such forward purchaser, shares of our common stock to hedge such forward purchaser’s exposure under such forward sale agreement. All of the net proceeds from the sale of such borrowed shares will be paid to the applicable forward purchaser (or one or more of its affiliates). Each forward purchaser will be either an agent or an affiliate of an agent. As a result, an agent or its affiliate will receive the net proceeds from any sale of borrowed shares of our common stock made in connection with any forward sale agreement.

S-7

PLAN OF DISTRIBUTION (CONFLICTS OF INTEREST)

Under the sales agreement, shares of our common stock having an aggregate gross sales price of up to $3,000,000,000 may be offered and sold from time to time to or through the agents, as our sales agents or, if applicable, as forward sellers.

Sales of shares of our common stock, if any, will be made in negotiated transactions, including block trades, or transactions that are deemed to be “at the market” offerings as defined in Rule 415 under the Securities Act, by means of ordinary brokers’ transactions at market prices prevailing at the time of sale, including sales made directly on the NYSE, sales made to or through a market maker and sales made through other securities exchanges or electronic communications networks or by any other method permitted by applicable law as otherwise agreed between the applicable agent and us. As sales agents, the agents will not engage in any transactions that stabilize the price of our common stock.

The sales agreement contemplates that, in addition to the issuance and sale by us of shares of our common stock to or through the agents, we may enter into separate forward sale agreements with each of the forward purchasers. If we enter into a forward sale agreement with any forward purchaser, we expect that such forward purchaser (or its affiliate) will attempt to borrow from third parties and sell, through the relevant agent, acting as sales agent for such forward purchaser, shares of our common stock to hedge such forward purchaser’s exposure under such forward sale agreement. We will not receive any proceeds from any sale of shares of our common stock borrowed by a forward purchaser (or its affiliate) and sold through a forward seller.

No agent is required to sell any specific number or dollar amount of shares of our common stock, but each agent has agreed to use its commercially reasonable efforts, consistent with its normal trading and sales practices and applicable law and regulations, as our sales agent or as forward seller, and subject to the terms and conditions of the sales agreement and, in the case of shares offered through such agent as forward seller, the relevant forward sale agreement, to sell shares of our common stock, on mutually agreed terms between the agent and us. Shares of our common stock offered and sold through the agents, as our sales agents or as forward sellers, pursuant to this prospectus supplement and the accompanying prospectus, will be offered and sold through only one agent on any given day.

The agents, as our sales agents or as forward sellers, will offer shares of our common stock subject to the terms and conditions of the sales agreement and, in the case of shares offered through such agents as forward sellers, the relevant forward sale agreement, as agreed upon by us, the agents and any relevant forward purchasers. We will designate the maximum amount of shares of our common stock to be sold through the agents or otherwise determine such maximum amount together with such agents and relevant forward purchasers. Subject to the terms and conditions of the sales agreement, the applicable agent will use commercially reasonable efforts, consistent with its normal trading and sales practices and applicable law and regulations, to sell on our behalf or, in the case of shares offered through such agent as forward seller, on the behalf of the relevant forward purchaser, all of the designated common stock. We may instruct an agent not to sell shares of our common stock if the sales cannot be effected at or above the price designated by us in any such instruction. We or an agent may suspend the offering of shares of our common stock being made through such agent under the sales agreement upon proper notice to the other party.

An agent will provide written confirmation to us following the close of trading on the NYSE each day in which shares of our common stock are sold by such agent under the sales agreement. Each confirmation will include the number of shares sold on that day, the gross sales price per share, the net proceeds to us and the compensation payable by us to such agent.

Except in connection with a forward sale agreement as discussed below, we expect that settlement for sales of shares of our common stock will occur, unless the parties agree otherwise, on the first business day that is also a trading day following the date on which any sales were made in return for payment of the proceeds to us net of compensation paid by us to the applicable agent. There is no arrangement for funds to be received in an escrow, trust or similar arrangement.

S-8

Under the terms of the sales agreement, we may also sell shares of our common stock to one or more of the agents as principal, at a price per share to be agreed upon at the time of sale. If we sell shares of our common stock to one or more of the agents as principal, we will enter into a separate terms agreement with such agent or agents, as the case may be, and we will describe the terms of the offering of those shares of our common stock in a separate prospectus supplement or pricing supplement.

We will report at least quarterly the number of shares of our common stock sold to or through the agents under the sales agreement and any forward sale agreement, the net proceeds to us and the aggregate compensation paid by us to the agents in connection with the sales of such shares.

In connection with the sale of shares of our common stock, each agent may, and in connection with sales of shares of our common stock purchased by an agent as principal will, be deemed to be an “underwriter” within the meaning of the Securities Act, and the compensation paid to the agent may, or will, as applicable, be deemed to be underwriting commissions. We have agreed in the sales agreement to provide indemnification and contribution to the agents and forward purchasers against certain civil liabilities, including liabilities under the Securities Act.

Our common stock is an “actively-traded security” excepted from the requirements of Rule 101 of Regulation M under the Exchange Act by Rule 101(c)(1) of Regulation M under the Exchange Act. If we or an agent has reason to believe that our common stock is no longer an “actively-traded security” as defined under Rule 101(c)(1) of Regulation M under the Exchange Act, the applicable party will promptly so notify the other party, and sales of shares of our common stock under the sales agreement will be suspended until that or other exemptive provisions have been satisfied in the judgment of us and the agent.

We estimate that the total expenses of the offering payable by us, excluding commissions under the sales agreement, will be approximately $800,000. If we have not sold shares of our common stock under the sales agreement having an aggregate gross sales price of at least $300,000,000 by the 18-month anniversary of the sales agreement, we have agreed to reimburse the agents and the forward purchasers for certain of their expenses in an amount not to exceed $400,000.

The offering of our common stock pursuant to the sales agreement will terminate upon the earlier of (1) the sale of shares of our common stock subject to the sales agreement having an aggregate gross sales price of $3,000,000,000 and (2) the termination of the sales agreement by the agents, the forward purchasers or us. An agent or forward purchaser may terminate the sales agreement at any time but only with respect to itself. We may terminate the sales agreement at any time.

No action has been taken in any jurisdiction (except in the United States) that would permit a public offering of the shares of our common stock, or the possession, circulation or distribution of this prospectus supplement, the accompanying prospectus or any free writing prospects or other material or advertisements relating to us or this offering, where action for that purpose is required. Accordingly, the shares of our common stock may not be offered or sold, directly or indirectly, and neither this prospectus supplement, the accompanying prospectus nor any free writing prospects or other material or advertisements in connection with this offering may be distributed or published in or from any other country or jurisdiction except in compliance with any applicable rules and regulations of any such country or jurisdiction.

The agents may offer and sell the shares of our common stock to the public through one or more of their respective affiliates or other registered broker-dealers or selling agents.

The descriptions of certain provisions of the sales agreement appearing above and elsewhere in this prospectus supplement are not complete and are subject to, and qualified in their entirety by reference to, the terms and provisions of such sales agreement. A copy of the sales agreement has been or will be filed as an exhibit to a document incorporated by reference in the accompanying prospectus and may be obtained as described under “Where You Can Find More Information” in the accompanying prospectus.

S-9

Commissions and Discounts

Each agent will receive from us a commission that will not exceed, but may be lower than, 1.0% of the gross sales price of all shares of our common stock sold through it as our sales agent under the sales agreement. We may also agree with the applicable agent to sell shares of our common stock using sales efforts and methods that may constitute “distributions” within the meaning of Rule 100 of Regulation M under the Exchange Act and for which we may agree to pay the applicable agent a commission that may exceed 1.0% of the gross sales price.

In connection with each forward sale agreement, the applicable agent, as forward seller, will receive a commission, in the form of a reduction to the initial forward price under the related forward sale agreement, at a mutually agreed rate that will not (except as provided below) exceed, but may be lower than, 1.0% of the volume-weighted average of the gross sales price per share of all of the borrowed shares of our common stock sold through such agent, as forward seller, during the applicable forward selling period for such shares (subject to certain possible adjustments to such gross sales price for daily accruals and any quarterly dividends having an “ex-dividend” date during such forward selling period).

In any sale of shares of our common stock to an agent as principal, we may agree to pay the applicable agent an underwriting discount or commission that may exceed 1.0% of the gross sales price per share sold to such agent, as principal.

The sales proceeds, after deducting sales commissions (and underwriting discounts, if any), any expenses payable by us and any transaction fees imposed by any governmental, regulatory, or self-regulatory organization in connection with the sales, will equal our net proceeds for the sale of such shares.

Sales Through the Agents as Forward Sellers

If we enter into a forward sale agreement with any forward purchaser, we expect that such forward purchaser (or its affiliate) will attempt to borrow from third parties and sell, through the relevant agent, acting as sales agent for such forward purchaser, shares of our common stock to hedge such forward purchaser’s exposure under such forward sale agreement. All of the net proceeds from the sale of such borrowed shares will be paid to the applicable forward purchaser (or one or more of its affiliates). Each forward purchaser will be either an agent or an affiliate of an agent. As a result, an agent or its affiliate will receive the net proceeds from any sale of borrowed shares of our common stock made in connection with any forward sale agreement.

In connection with any forward sale agreement, we will deliver instructions to the relevant agent directing such agent, as forward seller, to sell the applicable borrowed shares of our common stock on behalf of the relevant forward purchaser. Upon its acceptance of such instructions, such agent has agreed to use its commercially reasonable efforts, consistent with its normal trading and sales practices and applicable law and regulations, to sell such shares of our common stock, as forward seller on behalf of such forward purchaser, on the terms and subject to the conditions set forth in the sales agreement. We may instruct such agent as to the amount of common stock to be sold by it as forward seller and may also instruct such agent not to sell such common stock if the sales cannot be effected at or above a price designated by us. We or the applicable agent may at any time immediately suspend the offering of shares of our common stock through such agent, as forward seller, upon notice to the other parties.

Pursuant to a forward sale agreement, subject to our authorization of such issuances, we will have the right to issue and deliver to the forward purchaser party thereto a specified number of shares of our common stock on the terms and subject to the conditions set forth therein, or, alternatively, to elect cash settlement or net share settlement, for all or any portion of such shares. If we elect or are deemed to have elected to physically settle any forward sale agreement by delivering shares of our common stock, we will receive an amount of cash from the relevant forward purchaser equal to the product of (1) the initial forward price per share under such forward sale agreement and (2) the number of shares of our common stock as to which we have elected or are deemed to have

S-10

elected physical settlement, subject to the price adjustment and other provisions of such forward sale agreement as described below. The initial forward price per share under each forward sale agreement will equal the product of (1) an amount equal to one minus the applicable forward selling commission and (2) the volume weighted average price per share at which the borrowed shares of our common stock were sold pursuant to the sales agreement by the relevant agent, as forward seller, during the applicable forward selling period for such shares to hedge the relevant forward purchaser’s exposure under such forward sale agreement (subject to certain possible adjustments to such gross sales price for daily accruals and any quarterly dividends having an “ex-dividend” date during such forward selling period). Thereafter, the forward price will be subject to adjustment on a daily basis based on a floating interest rate factor equal to a specified daily rate less a spread. If the specified daily rate is less than the applicable spread on any day, the interest rate factor will result in a daily reduction of the forward price. In addition, the forward price will be subject to decrease on certain dates specified in the relevant forward sale agreement by the amount per share of quarterly dividends we expect to declare on our common stock during the term of such forward sale agreement.

We expect that, before any issuance of shares of our common stock upon physical settlement or net share settlement of any forward sale agreement, the shares issuable upon settlement of such forward sale agreement will be reflected in our diluted earnings per common share calculations using the treasury stock method. Under this method, the number of shares of our common stock used in calculating diluted earnings per common share will be deemed to be increased by the excess, if any, of the number of shares that would be issued upon physical settlement of such forward sale agreement over the number of shares that could be purchased by us in the market (based on the average market price during the relevant forward selling period specified in such forward sale agreement) using the proceeds receivable upon settlement (based on the adjusted forward price at the end of the relevant reporting period).

Consequently, prior to physical or net share settlement of any forward sale agreement and subject to the occurrence of certain events, we anticipate there will be no dilutive effect on our earnings per common share as a result of such forward sale agreement except during periods when the average market price of our common stock is above the per share adjusted forward price of such forward sale agreement, subject to increase or decrease based on a specified daily rate less a spread, and subject to decrease by amounts related to expected dividends on our common stock during the term of that particular forward sale agreement. However, if we decide to physically or net share settle any forward sale agreement, delivery of shares of our common stock by us will result in dilution to our earnings per common share.

We will generally have the right, in lieu of physical settlement of any forward sale agreement, to elect cash or net share settlement in respect of any or all of the shares of our common stock subject to such forward sale agreement. If we elect to cash or net share settle all or any part of any forward sale agreement, we would expect the relevant forward purchaser or its affiliate to purchase shares of our common stock in secondary market transactions over an unwind period to:

If the price of our common stock at which these purchases are made by such forward purchaser (or its affiliate) is below the relevant forward price, such forward purchaser will pay us such difference in cash (if we elect to cash settle) or deliver to us a number of shares of our common stock having a market value equal to such difference (if we elect to net share settle). If the price of our common stock at which these purchases are made by such forward purchaser (or its affiliate) exceeds the applicable forward price, we will pay such forward purchaser an amount in cash equal to such difference (if we elect to cash settle) or we will deliver to such forward purchaser a number of shares of our common stock having a market value equal to such difference (if we elect to

S-11

net share settle). Any such difference could be significant and could result in our receipt of a significant amount of cash or number of shares of our common stock from such forward purchaser or require us to pay a significant amount of cash or deliver a significant number of shares of our common stock to such forward purchaser.

In addition, the purchase of shares of our common stock by a forward purchaser or its affiliate to unwind the forward purchaser’s hedge position could cause the price of our common stock to increase above the price that would have prevailed in the absence of those purchases (or prevent a decrease in such price), thereby increasing the amount of cash (in the case of cash settlement) or the number of shares (in the case of net share settlement) that we would owe such forward purchaser upon settlement of the applicable forward sale agreement or decrease the amount of cash (in the case of cash settlement) or the number of shares (in the case of net share settlement) that such forward purchaser would owe us upon settlement of the applicable forward sale agreement.

Each forward purchaser will have the right to accelerate its forward sale agreement (or, in certain cases, the portion thereof that the forward purchaser determines is affected by the relevant event) and require us to physically settle the forward sale agreement on a date specified by the forward purchaser if, subject to a prior notice requirement:

A forward purchaser’s decision to exercise its right to accelerate all or a portion of the settlement of its forward sale agreement and to require us to physically settle the relevant shares will be made irrespective of our interests, including our need for capital. In such cases, we could be required to issue and deliver shares of our common stock under the terms of the physical settlement provisions of the applicable forward sale agreement irrespective of our capital needs, which would result in dilution to our earnings per common share and may adversely affect the market price of our common stock, Series C preferred stock and any other series of preferred stock we may issue in the future.

In addition, upon certain events of bankruptcy or insolvency relating to us, the forward sale agreements will terminate without further liability of the parties thereto. Following any such termination, we would not issue any shares of our common stock pursuant to such forward sale agreements, and we would not receive any proceeds pursuant to such forward sale agreements.

The descriptions of certain provisions of the forward sale agreements appearing above and elsewhere in this prospectus supplement are not complete and are subject to, and qualified in their entirety by reference to, the

S-12

terms and provisions of such forward sale agreements. A form of the forward sale agreement is included as an exhibit to the sales agreement, and the sales agreement has been or will be filed as an exhibit to a document incorporated by reference in the accompanying prospectus and may be obtained as described under “Where You Can Find More Information” in the accompanying prospectus.

Conflicts of Interest

As described above under “Use of Proceeds,” we may use any net proceeds from this offering, including pursuant to the settlement of any forward sale agreement, to repay commercial paper and potentially other indebtedness. One or more of the agents participating in this offering and/or their affiliates may hold positions in our commercial paper or other indebtedness of ours, three of the agents act as dealers under our commercial paper program, and affiliates of all of the agents are lenders under our credit facilities. To the extent that net proceeds from this offering, including pursuant to the settlement of any forward sale agreement, are applied to repay any of our outstanding indebtedness (including commercial paper, bank loans or other indebtedness) held by any of the agents or their affiliates, they will receive proceeds from this offering through the repayment of that indebtedness.

Other Relationships

The agents, the forward purchasers and their respective affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing and brokerage activities. Some or all of the agents, the forward purchasers and/or their affiliates have acted and/or are acting as lenders to and/or have from time to time performed and/or are performing certain investment banking, advisory, general financing, trustee and commercial banking and other commercial transactions and services for us and/or our affiliates for which they have received and in the future may receive customary fees and expenses. The agents, the forward purchasers and their respective affiliates may, from time to time, engage in other transactions with or perform other services for us and our affiliates in the ordinary course of their business for which they receive customary fees and expenses. In addition, affiliates of all of the agents are lenders under our credit facilities and three of the agents act as dealers under our commercial paper program.

In addition, in the ordinary course of their business activities, the agents, forward purchasers, and their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers, and such investment and securities activities may involve securities and/or instruments of ours or our affiliates. If any of the agents, forward purchasers or their respective affiliates has a lending relationship with us, certain of those agents, forward purchasers or their respective affiliates routinely hedge and certain other of those agents, forward purchasers or their respective affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, these agents, forward purchasers and their respective affiliates would hedge such exposure by entering into transactions which may consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the shares offered pursuant to the sales agreement. Any such credit default swaps or short positions could adversely affect future trading prices of the securities offered in this offering. The agents, forward purchasers and their respective affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

DESCRIPTION OF CAPITAL STOCK

Unless indicated differently in a prospectus supplement or free writing prospectus, this section describes some of the terms of our common stock and preferred stock, articles of incorporation and bylaws. The following description is not complete and is qualified in its entirety by reference to our articles of incorporation (including the certificate of determination for our outstanding series C preferred stock and the certificate of determination for any other series of our preferred stock that may be issued and outstanding in the future) and bylaws. Therefore, you should read carefully the more detailed provisions of our articles of incorporation (including the certificate of determination for our outstanding series C preferred stock and the certificate of determination for any other series of our preferred stock that may be issued and outstanding in the future) and bylaws, which are incorporated by reference herein and are filed or will be filed as exhibits to the registration statement of which this prospectus is a part and may be obtained as described under “Where You Can Find More Information.” Unless otherwise expressly stated or the context otherwise requires, references to “we,” “us,” “our,” “Sempra” and similar references under this caption “Description of Capital Stock” mean Sempra excluding its consolidated entities.

The authorized capital stock of Sempra consists of (i) 1,125,000,000 shares of common stock, without par value, and (ii) 50,000,000 shares of preferred stock. As of May 19, 2023, there were 314,652,826 issued and outstanding shares of our common stock and 900,000 issued and outstanding shares of our preferred stock. No other classes of capital stock are authorized under our articles of incorporation.

Common Stock

The holders of our common stock are entitled to receive, ratably, such dividends as our board of directors may from time to time declare, subject to any rights of holders of outstanding shares of any series of our preferred stock to receive dividends before dividends may be paid on our common stock.

In the event of any liquidation, dissolution or winding up of Sempra, whether voluntary or involuntary, the holders of shares of our common stock are entitled, subject to any rights of the holders of outstanding shares of any series of our preferred stock to receive distributions in such event before any distributions are made to holders of our common stock, to receive, ratably, any of our remaining assets after the discharge of our liabilities.

Except as otherwise provided by law, each holder of our common stock is entitled to one vote per share on each matter submitted to a vote of our shareholders, subject to the voting rights, if any, of holders of outstanding shares of any series of our preferred stock, which could include the right to vote separately as a class or series, or the right to vote together with the common stock as a single class.

At each annual meeting of our shareholders, each director will be elected to hold office until the next annual meeting of shareholders and until a successor has been elected and qualified. Pursuant to our bylaws, directors standing for election in an uncontested election (as defined below) will be elected by the affirmative vote of a majority of the shares entitled to vote for them represented and voting at a duly held meeting at which a quorum is present (and such affirmative votes must also represent more than 25% of the outstanding shares entitled to vote in the election of such directors). In any election of directors that is not an uncontested election, the candidates receiving the highest number of affirmative votes of the shares entitled to vote for them, up to the number of directors to be elected by those shares, will be elected and votes against a director and votes withheld will have no effect. The rights of holders of our common stock to elect directors are subject to the voting rights, if any, of holders of outstanding shares of any series of our preferred stock, which could include: (i) voting as a separate class or series, the right to elect one or more directors, or (ii) voting together with our common stock as a single class, the right to vote in the election of directors generally. Our bylaws define an “uncontested election” as, in general, an election of directors in which the number of candidates for election does not exceed the number of directors to be elected by our shareholders at that election, determined at the times specified in our bylaws. Our articles of incorporation provide that none of our shareholders may cumulate votes in the election of directors.

9

Our common stock does not contain any conversion rights or sinking fund or redemption provisions. Holders of our common stock are not entitled to preemptive rights to subscribe for or purchase any part of any new or additional issue of stock or securities convertible into stock.

Our board of directors is expressly authorized to make, amend or repeal our bylaws, without any action on the part of the shareholders, except as otherwise required by applicable California law, solely by the affirmative vote of at least two-thirds of the authorized number of directors. Our bylaws may also be amended or repealed by our shareholders, by the approval of the outstanding shares (as defined in Section 152 of the Corporations Code of the State of California) of Sempra.

Preferred Stock

The board of directors of Sempra is authorized, without the need for a vote or other action of our shareholders, to cause the issuance of shares of our preferred stock from time to time in one or more series and to determine the number of shares and designation of the preferred stock of any series, to increase or decrease (but not below the number of shares of such series then outstanding) the number of shares of any such series subsequent to the issuance of shares of that series, and to determine or alter the rights, preferences, privileges and restrictions granted to or imposed upon such series, which may include, among other things, dividend and liquidation rights and preferences, rights to convert such shares into common stock, voting rights and other rights. Accordingly, our board of directors could cause the issuance of one or more series of our preferred stock ranking senior to the common stock with respect to dividends or distributions in the event of our liquidation, dissolution or winding up or with voting or other rights that could dilute or otherwise adversely affect the voting or other rights and economic interests of holders of our common stock. Likewise, our board of directors could cause the issuance of one or more series of our preferred stock ranking on parity with or senior to one or more other series of our preferred stock (subject to the terms of any one or more other series of our preferred stock, if any, then outstanding) with respect to dividends or distributions in the event of our liquidation, dissolution or winding up or with voting or other rights that could dilute or otherwise adversely affect the voting rights (if any) or other rights and economic interests of the holders of any such other series of preferred stock.

The series C preferred stock is a series of our preferred stock, without par value. As of May 19, 2023, a total of 900,000 shares of our series C preferred stock were outstanding. A copy of the certificate of determination setting forth the terms of the series C preferred stock has been filed as Exhibit 4.8 to the registration statement of which this prospectus is a part and is incorporated by reference herein.

In the event that we issue any series of preferred stock pursuant to this prospectus, we will describe the terms of such series of preferred stock in a supplement to this prospectus and, if applicable, a free writing prospectus.

Anti-Takeover Effects of our Articles of Incorporation and Bylaws

Certain provisions of our articles of incorporation and bylaws could have the effect of delaying, deterring or preventing another party from acquiring or seeking to acquire control of us. These provisions are intended to discourage certain types of coercive takeover practices and inadequate takeover bids and to encourage anyone seeking to acquire control of us to negotiate first with our board of directors. However, these provisions could also delay, deter or prevent a change of control or other takeover of our company that our shareholders might consider to be in their best interests, including transactions that might result in a premium being paid over the market prices of our common stock and any outstanding preferred stock, and may also limit the prices that investors are willing to pay in the future for our common stock and any outstanding preferred stock. These provisions may also have the effect of preventing changes in our management. Our articles of incorporation and bylaws include anti-takeover provisions that:

10

Limitation on Liability of Directors; Indemnification of Directors and Officers

Our articles of incorporation provide that the liability of our directors for monetary damages shall be eliminated to the fullest extent permissible under California law. Section 317 of the Corporations Code of the State of California permits a corporation to provide indemnification to its directors, officers and agents under certain circumstances. Our bylaws provide for mandatory indemnification of our directors and officers, subject to the limitations set forth therein. In addition, our articles of incorporation provide us with the power, by bylaw, agreement or otherwise, to provide indemnification of our directors, officers and other agents to the fullest extent permissible under California law and, subject to certain limitations, in excess of the indemnification expressly permitted under Section 317 of the Corporations Code of the State of California. We believe that this limitation of liability and these indemnification provisions are useful to attract and retain qualified directors and officers.

Listing of our Common Stock

Our common stock is listed on the New York Stock Exchange under the trading symbol “SRE” and the Mexican Stock Exchange (Bolsa Mexicana de Valores, S.A.B. de C.V.) under the trading symbol “SRE.MX.”

Listing of our Preferred Stock

Our series C preferred stock is not listed on any securities exchange or trading facility or included in any automated dealer quotation system.

Registrar and Transfer Agent

The registrar and transfer agent for our common stock and series C preferred stock is American Stock Transfer & Trust Company LLC.

DESCRIPTION OF DEBT SECURITIES

Unless indicated differently in a prospectus supplement or a free writing prospectus, the following is a general description of some of the terms and provisions of the debt securities Sempra may offer and sell by this prospectus. To the extent the terms and provisions of any series of debt securities modify the general terms and provisions described below, such modifications will be described in a prospectus supplement or free writing prospectus relating to such series. The debt securities may be issued as senior debt securities or subordinated debt securities (which may include junior subordinated debt securities, senior subordinated debt securities and subordinated debt securities of any other relative ranking). Unless otherwise expressly stated or the context otherwise requires, references to “we,” “us,” “our,” “Sempra” and similar references under this caption “Description of Debt Securities” mean Sempra excluding its consolidated entities.

The senior debt securities will be governed by an indenture (the “senior indenture”) between us and the trustee named therein and the subordinated debt securities will be governed by an indenture (the “subordinated indenture”) between us and the trustee named therein. The senior indenture and the subordinated indenture are hereinafter sometimes referred to as, collectively, the “indentures” and individually, an “indenture.” Each indenture gives us broad authority to set the particular terms of each series of debt securities, including the right to modify certain of the terms contained in the indenture. The particular terms of a series of debt securities and the extent, if any, to which the particular terms of the series modify the terms of the applicable indenture will be described in the applicable prospectus supplement, or a free writing prospectus, relating to such series of debt securities.

Each indenture contains the full legal text of the matters described in this section. The following description of certain provisions of the indentures and our debt securities is not complete and is subject to and qualified in its entirety by reference to all the provisions of the applicable indenture, including definitions of terms used in such indenture, and the certificates evidencing the debt securities of each series, copies of which have been or will be filed or incorporated by reference as exhibits to the registration statement of which this prospectus is a part or to a document incorporated by reference in this prospectus and which may be obtained as described under “Where You Can Find More Information.” We also include references in parentheses to particular sections of the applicable indenture. Whenever we refer to particular sections or defined terms of the indentures in this prospectus or a prospectus supplement or free writing prospectus, those sections or defined terms are incorporated by reference in this prospectus or the applicable prospectus supplement or free writing prospectus. This description also is subject to and qualified by reference to the description of the particular terms of a particular series of debt securities described in the applicable prospectus supplement or free writing prospectus.

General

Sempra may issue an unlimited amount of debt securities under the indentures in one or more series. Sempra is not required to issue all debt securities of one series at the same time and, unless otherwise provided for a particular series of debt securities in the applicable prospectus supplement or a free writing prospectus, Sempra may, without notice to or consent of the holders of the debt securities of any series, increase the aggregate principal amount of the debt securities of any series and issue additional debt securities of such series up to the maximum aggregate principal amount authorized with respect to such series as increased from time to time. Any additional debt securities so issued shall have the same form and terms (other than offering price, the date of issuance and, under certain circumstances, the date from which interest thereon shall begin to accrue and the first interest payment date) and shall carry the same right to receive accrued and unpaid interest as the debt securities previously issued, and such additional debt securities shall form a single series with the debt securities previously issued under the applicable indenture, provided that such additional debt securities of such series shall be fungible with the debt securities of such series previously issued for United States federal income tax purposes.

Unless otherwise provided in a prospectus supplement or free writing prospectus, the debt securities of Sempra will not be subject to a sinking fund or entitled to any guarantees and you will not be permitted to require Sempra to redeem or repurchase the debt securities at your option.

12

Unless otherwise provided in a prospectus supplement or free writing prospectus, the relevant trustee shall serve as the initial paying agent and security registrar for the debt securities of Sempra.

The debt securities of Sempra will be its unsecured obligations.

Prior to the issuance of each series of debt securities, the terms of the particular series of debt securities will be specified in either (i) a supplemental indenture, (ii) a board resolution or (iii) in one or more officers’ certificates of Sempra. We refer you to the applicable prospectus supplement or free writing prospectus for a description of the following terms of each series of debt securities:

13

(See Section 301.)

Ranking

The senior debt securities will be the unsecured and unsubordinated obligations of Sempra. The indebtedness represented by the senior debt securities will rank equally in right of payment with all of the other unsecured and unsubordinated indebtedness of Sempra. The indebtedness represented by the subordinated debt securities will rank junior and subordinate in right of payment to the prior payment in full of the existing and future Senior Indebtedness (as defined with respect to each series of subordinated debt securities) of Sempra, to the extent and in the manner set forth below under “—Subordination” or as may be set forth in the applicable prospectus supplement or free writing prospectus. In addition, the subordinated debt securities will be effectively subordinated in right of payment to any secured indebtedness Sempra may have or may incur (to the extent of the value of the collateral securing such secured indebtedness). The term “Senior Indebtedness,” when used with respect to the subordinated debt securities of any series, has the meaning set forth below under “—Subordination” unless a different definition shall be set forth in the applicable prospectus supplement or a free writing prospectus relating to the subordinated debt securities of such series. The debt securities are obligations of Sempra exclusively, and are not the obligations of any of its subsidiaries, other consolidated entities, equity method investments or other affiliates. Sempra conducts its operations primarily through its subsidiaries or entities it does not control, including equity method investments, and substantially all of its consolidated assets are held by its subsidiaries. The debt securities will be effectively subordinated to all existing and future indebtedness and other liabilities of Sempra’s subsidiaries.

Holding Company Structure

Sempra conducts its operations primarily through its subsidiaries or entities it does not control, including equity method investments, and substantially all of its consolidated assets are held by its subsidiaries.

14

Accordingly, Sempra’s ability to meet its obligations under its debt securities largely depends on cash flows from its subsidiaries and equity method investments, which in turn depend on their ability to execute their business strategies and generate cash flows in excess of their own expenditures, dividend payments to third-party owners (if any) and debt and other obligations. These subsidiaries and equity method investments are separate and distinct legal entities that are not obligated to pay dividends or make loans or distributions to us and could be precluded from doing so by legislation, regulation, court order or contractual restrictions, in times of financial distress or in other circumstances, and they have no obligation to pay any amounts due on the Sempra debt securities or to make any funds available for payment of amounts due on these debt securities.

Because Sempra is a holding company, its obligations under the debt securities will be structurally subordinated to all existing and future indebtedness and other liabilities of its subsidiaries. Therefore, Sempra’s rights and the rights of its creditors, including the rights of the holders of the debt securities issued by Sempra, to participate in the assets of any subsidiary upon the liquidation or reorganization of the subsidiary will be subject to the prior claims of the subsidiary’s creditors. To the extent that Sempra may itself be a creditor with recognized claims against any of its subsidiaries, Sempra’s claims would still be effectively subordinated to any security interest in, or mortgages or other liens on, the assets of the subsidiary and would be subordinated to any indebtedness or other liabilities of the subsidiary that are senior to the claims held by Sempra. Sempra expects to incur, and expects that its subsidiaries will incur, substantial additional amounts of indebtedness.

Payment of Debt Securities—Interest

Sempra will pay interest on the debt securities on each interest payment date to the person in whose name the debt securities are registered as of the close of business on the regular record date relating to the interest payment date.

However, if we default in paying interest on a debt security, we will pay defaulted interest, at our election, in either of the two following ways:

(See Section 307.)

Payment of Debt Securities—Principal

Sempra will pay principal of and any premium on the debt securities at stated maturity, upon redemption or as otherwise required, upon presentation of the debt securities at the office of the paying agent, which initially will be the trustee or such other paying agent designated in accordance with the applicable indenture. Any other paying agent initially designated for the debt securities of a particular series will be named in the applicable prospectus supplement or free writing prospectus.

If any interest payment date, redemption date or the maturity date of the debt securities is not a business day at any place of payment, then payment of the principal, premium, if any, and interest may be made on the next

15

business day at that place of payment. In that case, no interest will accrue on the amount payable for the period from and after the applicable interest payment date, redemption date or maturity date, as the case may be (See Section 113.)

In its discretion, Sempra may appoint one or more additional paying agents and security registrars and change or designate one or more additional places for payment. Unless otherwise specified in the applicable prospectus supplement or free writing prospectus, a place for payment of the debt securities will be maintained in the Borough of Manhattan, The City of New York, New York. (See Section 1002.)

Form; Transfers; Exchanges

Unless we indicate differently in the applicable prospectus supplement or free writing prospectus, the debt securities initially will be issued in book-entry form and represented by one or more global securities deposited with, or on behalf of, The Depository Trust Company, New York, New York, as depositary, which we refer to as “DTC” or the “depositary” in this prospectus, and registered in the name of Cede & Co., its nominee. This means that you will not be entitled to receive a certificate for the debt securities that you purchase except under the limited circumstances described below under the caption “Global Securities.” If any of the debt securities are issued in certificated form, they will be issued only in fully registered form without coupons, in denominations of, with respect to senior debt securities, $1,000 or integral multiples thereof or, in the case of subordinated debt securities, $2,000 or integral multiples of $1,000 in excess thereof.

So long as the debt securities are in book-entry form, you will receive payments and may transfer debt securities only through the facilities of DTC and its direct and indirect participants as described below under the caption “Global Securities.” We will maintain an office or agency in the Borough of Manhattan, The City of New York where notices and demands in respect of the debt securities and the indentures may be delivered to us and where certificated debt securities may be surrendered for payment, registration of transfer or exchange. That office will initially be an office of the trustee, which is currently located at 100 Wall Street, Suite 1600, New York, New York 10005. (See Section 1002). You may have your debt securities divided into debt securities of smaller authorized denominations or combined into debt securities of larger authorized denominations, as long as the total principal amount is not changed. This is called an “exchange.” (See Section 305.)

You may exchange or transfer debt securities at the office of the trustee. The trustee acts as our agent for registering debt securities in the names of holders and transferring debt securities. Sempra may appoint another agent or act as its own agent for this purpose. The entity performing the role of maintaining the list of registered holders is called the “security registrar.” It will also perform transfers. (See Section 305.)

In our discretion, we may change the place for registration of transfer of the debt securities and for delivery of notices and demands in respect of the debt securities and the applicable indenture and we may remove and/or appoint one or more additional security registrars. (See Sections 305 and 1002.)

Except as otherwise provided in the applicable prospectus supplement or free writing prospectus, there will be no service charge for any transfer or exchange of the debt securities, but you may be required to pay a sum sufficient to cover any tax or other governmental charge payable in connection with the transfer or exchange.

We may block the transfer or exchange of (a) debt securities during a period of 15 days before giving any notice of redemption or (b) any debt security selected for redemption in whole or in part, except the unredeemed portion of any debt security being redeemed in part. (See Section 305.)

Optional Redemption

The redemption provisions, if any, applicable to the debt securities of any series will be set forth in the applicable prospectus supplement or free writing prospectus.

16

We will mail notice of any redemption at least 30 days, but not more than 60 days, before the redemption date to each registered holder of the debt securities to be redeemed. Once notice of redemption is mailed, the debt securities called for redemption will become due and payable on the redemption date and at the applicable redemption price, plus accrued and unpaid interest to the redemption date. If we elect to redeem all or a portion of the debt securities, that redemption will not be conditional upon receipt by the trustee or other paying agent of monies sufficient to pay the redemption price. (See Section 1104.)

Unless we default in payment of the redemption price and accrued interest, if any, from and after the redemption date the debt securities or portions thereof called for redemption will cease to bear interest. We will pay the redemption price and any accrued interest once the debt securities are surrendered for redemption. (See Section 1105.) If only part of a debt security is redeemed, the trustee will deliver new debt securities of the same series for the remaining portion without charge. (See Section 1106.)

In the event that we elect to redeem only a portion of the debt securities, the debt securities to be redeemed will be selected in accordance with the procedures of DTC, in the case of debt securities represented by a global security, or by the trustee as set forth in the applicable indenture, in the case of debt securities that are not represented by a global security. (See Section 1103.)

Events of Default

Unless indicated differently in a prospectus supplement, an “event of default” occurs with respect to the debt securities of any series if:

17

(See Section 501.)

No event of default with respect to a series of debt securities necessarily constitutes an event of default with respect to the debt securities of any other series issued under the applicable indenture.

As of May 19, 2023, the terms of approximately $750 million aggregate principal amount of outstanding senior debt securities that we previously issued under the senior indenture (the “prior senior debt securities”) included the event of default described in clause (e) of the first paragraph under the above heading “Events of Default” (a so-called “cross-default” event of default), with a threshold amount of at least $25 million. However, Sempra anticipates that future senior debt securities offered by Sempra will not include the event of default described in clause (e) of the first paragraph under the above heading “Events of Default” or any other “cross-default” event of default. Accordingly, if a series of debt securities offered hereby does not include a “cross-default” event of default, then the principal of and interest on the prior senior debt securities may be declared due and payable immediately upon the occurrence of a “cross-default” event of default, while the holders of the senior debt securities of such series offered hereby will not be entitled to accelerate such debt securities as a result of such event.

Remedies

Acceleration

If an event of default occurs and is continuing with respect to any series of debt securities, then either the trustee or the registered holders of at least 25% in principal amount of the outstanding debt securities of that series may declare the principal amount of all of the debt securities of that series, together with accrued and unpaid interest thereon, to be due and payable immediately, and upon any such declaration the principal of and accrued and unpaid interest on the debt securities of that series shall become immediately due and payable (notwithstanding, in the case of subordinated debt securities, if the terms of the subordinated debt securities of such series permit Sempra to defer or extend the payment of interest thereon, any such extension or deferral). (See Section 502.)

18

Rescission of Acceleration

After the declaration of acceleration has been made with respect to any series of debt securities and before the trustee has obtained a judgment or decree for payment of the money due, the event of default giving rise to the declaration will be deemed to have been waived and the declaration and its consequences will be rescinded and annulled, if:

(See Section 502.)

For more information as to waiver of defaults, see “—Waiver of Default and of Compliance” below.

Control by Registered Holders; Limitations

If an event of default with respect to the debt securities of any series occurs and is continuing, the registered holders of a majority in principal amount of the outstanding debt securities of that series (voting as a single class without regard to the holders of outstanding debt securities of any other series that may also be in default) will have the right to direct the time, method and place of:

These rights of registered holders to give directions are subject to the following limitations:

The trustee may also take any other action it deems proper which is not inconsistent with the registered holders’ direction. (See Sections 512 and 603.)

In addition, each indenture provides that no registered holder of debt securities of any series will have any right to institute any proceeding, judicial or otherwise, with respect to the applicable indenture or for the appointment of a receiver or for any other remedy thereunder unless:

19

Furthermore, no registered holder will be entitled to institute any action if and to the extent that the action would affect, disturb or prejudice the rights of other registered holders of debt securities under the applicable indenture. (See Section 507.)

However, each registered holder has an absolute and unconditional right to receive payment when due and to bring a suit to enforce that right. (See Section 508.)

Notice of Default

The trustee is required to give the registered holders of debt securities of the affected series notice of any default with respect to the debt securities of that series under the applicable indenture to the extent required by the Trust Indenture Act; except that, in the case of an event of default of the character specified above in clause (d) under “—Events of Default,” no notice will be given to such registered holders until at least 30 days after the occurrence of the default. (See Section 602.) The Trust Indenture Act currently permits the trustee to withhold notices of default (except for certain payment defaults) if the trustee in good faith determines the withholding of the notice to be in the interests of the registered holders.

We will furnish the trustee with an annual statement of whether or not we are in default in the performance or observance of any of the terms, provisions and conditions in the applicable indenture. (See Section 1005.)

Waiver of Default and of Compliance

The registered holders of a majority in principal amount of the outstanding debt securities of any series, voting as a single class without regard to the holders of outstanding debt securities of any other series that may also be in default, may waive, on behalf of all registered holders of the debt securities of that series, any past default under the applicable indenture, except a default in the payment of principal, premium (if any) or interest, or with respect to compliance with certain covenants or provisions of the applicable indenture that cannot be modified or amended without the consent of the registered holder of each outstanding debt security of that series. (See Section 513.)

Unless indicated differently in a prospectus supplement, compliance with certain covenants in the applicable indenture or otherwise provided with respect to debt securities of any series may be waived before the time specified for compliance by the registered holders of a majority in principal amount of the outstanding debt securities of such series. (See Section 1006.)

Consolidation, Merger and Conveyance of Assets as an Entirety; No Financial Covenants

Sempra has agreed not to consolidate or merge with or into any other entity, or to sell, transfer, lease or otherwise convey its properties and assets as an entirety or substantially as an entirety to any other entity, unless:

20

Neither of the indentures nor the debt securities contain any financial or other similar restrictive covenants.

(See Section 801.)

Modification of Indenture

Without Registered Holder Consent. Without the consent of any registered holders of debt securities outstanding under an indenture, Sempra and the trustee may enter into one or more supplemental indentures to such indenture for any of the following purposes:

(See Section 901.)

21

With Registered Holder Consent. Subject to the following sentence, Sempra and the trustee may, with some exceptions, amend or modify the applicable indenture with the consent of the registered holders of a majority in principal amount of the debt securities of each series affected by the amendment or modification. However, no amendment or modification may, without the consent of the registered holder of each outstanding debt security affected thereby:

A supplemental indenture which changes or eliminates any covenant or other provision of the applicable indenture expressly included solely for the benefit of holders of debt securities of one or more particular series will be deemed not to affect the rights under the applicable indenture of the holders of debt securities of any other series.

(See Section 902.)

Defeasance

Each indenture provides, unless the terms of the particular series of debt securities provide otherwise, that Sempra may, upon satisfying several conditions, cause itself to be discharged from its obligations, with some exceptions, with respect to any series of debt securities outstanding under such indenture, which we refer to as “defeasance.”

One condition Sempra must satisfy is the irrevocable deposit with the trustee, in trust, of money and/or government obligations which, through the scheduled payment of principal and interest on those obligations, would provide sufficient moneys to pay the principal of and any premium and interest on the debt securities of the applicable series on the maturity dates of the payments or upon redemption.

In addition, Sempra will be required to deliver an opinion of counsel to the effect that a holder of debt securities of the applicable series will not recognize income, gain or loss for federal income tax purposes as a result of the defeasance and will be subject to federal income tax on the same amounts, at the same times and in the same manner as if that defeasance had not occurred. The opinion of counsel must be based upon a ruling of the Internal Revenue Service or a change in law after the date of the applicable indenture.

(See Article XIII.)

22

Satisfaction and Discharge

The applicable indenture will cease to be of further effect with respect to any series of debt securities, and we will be deemed to have satisfied and discharged all of our obligations under the applicable indenture with respect to the debt securities of such series, except as noted below, when:

Notwithstanding the satisfaction and discharge of the applicable indenture with respect to any series of debt securities, Sempra will remain obligated to pay amounts due under certain provisions of the applicable indenture and to perform certain ministerial tasks as described in the applicable indenture.

(See Section 401.)

Resignation and Removal of the Trustee; Deemed Resignation

The trustee with respect to any series of debt securities may resign at any time by giving written notice to us. The trustee may also be removed with respect to the debt securities of any series by the registered holders of a majority in principal amount of the outstanding debt securities of such series. No resignation or removal of the trustee and no appointment of a successor trustee will become effective until the acceptance of appointment by a successor trustee in accordance with the requirements of the applicable indenture. (See Section 610.)

Subordination

Unless indicated differently in the applicable prospectus supplement or free writing prospectus, Sempra’s subordinated debt securities of each series will be subordinated in right of payment to the prior payment in full of all its Senior Indebtedness (as defined with respect to such series). This means that, with respect to the subordinated debt securities of any series, upon:

23

the holders of all of Sempra’s Senior Indebtedness (as defined with respect to the subordinated debt securities of such series) will be entitled to receive:

before the holders of any of the subordinated debt securities of such series are entitled to receive any payment. So long as any of the events in clauses (a), (b), or (c) above has occurred and is continuing, any amounts payable or assets distributable on the subordinated debt securities of such series will instead be paid or distributed, as the case may be, directly to the holders of such Senior Indebtedness (as defined with respect to the subordinated debt securities of such series) to the extent necessary to pay, in the case of clause (a) above, all amounts due or to become due upon all such Senior Indebtedness, or, in the case of clauses (b) and (c) above, all amounts due on all such Senior Indebtedness, and, if any such payment or distribution is received by the trustee under the subordinated indenture in respect of the subordinated debt securities of such series or by the holders of any of the subordinated debt securities of such series before all such Senior Indebtedness due and to become due or due, as applicable, is paid, the payment or distribution must be paid over to the holders of such unpaid Senior Indebtedness. Subject to paying the applicable Senior Indebtedness due and to become due in the case of clause (a) or the Senior Indebtedness due in the case of clauses (b) and (c), the holders of the subordinated debt securities of such series will be subrogated to the rights of the holders of such Senior Indebtedness to receive payments applicable to such Senior Indebtedness until the subordinated debt securities of such series are paid in full. (See Sections 1401 and 1403.)

Unless otherwise provided in an applicable prospectus supplement or free writing prospectus, “Senior Indebtedness” means, with respect to the subordinated debt securities of any series, (i) indebtedness of Sempra, whether outstanding at the date of the subordinated debt indenture or incurred, created or assumed after such date, (a) in respect of money borrowed by Sempra (including any financial derivative, hedging or futures contract or similar instrument, to the extent any such item is primarily a financing transaction) and (b) evidenced by debentures, bonds, notes, credit or loan agreements or other similar instruments or agreements issued or entered into by Sempra; (ii) all finance lease obligations of Sempra; (iii) all obligations of Sempra issued or assumed as the deferred purchase price of property, all conditional sale obligations of Sempra and all obligations of Sempra under any title retention agreement (but excluding, for the avoidance of doubt, trade accounts payable arising in the ordinary course of business and long-term purchase obligations); (iv) all obligations of Sempra for the reimbursement of any letter of credit, banker’s acceptance, security purchase facility or similar credit transaction; and (v) all obligations of the type referred to in clauses (i) through (iv) above of other persons for the payment of which Sempra is responsible or liable as obligor, guarantor or otherwise, except for any obligations, instruments or agreements of the type referred to in any of clauses (i) through (v) above that, by the terms of the instruments or agreements creating or evidencing the same or pursuant to which the same is outstanding, are subordinated or equal in right of payment to the subordinated debt securities of such series. (See Section 101.)

Due to the subordination, if assets of Sempra are distributed upon its dissolution, winding-up, liquidation or reorganization, holders of its Senior Indebtedness and other indebtedness and obligations that are not equal or junior to subordinated debt securities in right of payment will likely recover more, ratably, than holders of subordinated debt securities and it is possible that no payments will be made to the holders of subordinated debt securities.

The subordination provisions applicable to the subordinated debt securities of any series will cease to apply in the event of defeasance or satisfaction and discharge with respect to the subordinated debt securities of such series. (See Section 1307.)

The subordinated debt securities and the subordinated indenture do not limit Sempra or any of its subsidiaries’ ability to incur additional indebtedness, including, in the case of Sempra, Senior Indebtedness.

24

Sempra expects that it will incur, and that its subsidiaries will incur, substantial additional amounts of indebtedness, including, in the case of Sempra, Senior Indebtedness, in the future. The subordinated debt securities will be structurally subordinated to all indebtedness and other liabilities of Sempra’s subsidiaries. (See Section 301.)

Conversion Rights

The terms and conditions of any series of debt securities being offered that are convertible into common stock or other equity securities of Sempra will be set forth in the applicable prospectus supplement or free writing prospectus. These terms will include the conversion price, the conversion period, provisions as to whether conversion will be at the option of the holder or Sempra, the events requiring an adjustment of the conversion price and provisions affecting conversion if such series of debt securities are redeemed.

Miscellaneous Provisions

Each indenture provides that certain debt securities, including those for which payment or redemption money has been deposited or set aside in trust as described under “—Satisfaction and Discharge” above, will not be deemed to be “outstanding” in determining whether the registered holders of the requisite principal amount of the outstanding debt securities have given or taken any demand, direction, consent or other action under the indenture as of any date. (See Section 101.)

Sempra will be entitled to set any day as a record date for the purpose of determining the registered holders of outstanding debt securities of any series entitled to give or take any demand, direction, consent or other action under the applicable indenture, in the manner and subject to the limitations provided in the applicable indenture. In certain circumstances, the trustee also will be entitled to set a record date for action by registered holders of any series of outstanding debt securities. If a record date is set for any action to be taken by registered holders of particular debt securities, the action may be taken only by persons who are registered holders of the respective debt securities on the record date. (See Section 104.)

Governing Law

Each indenture and the debt securities will be governed by and construed in accordance with the laws of the State of New York, without regard to conflicts of laws principles thereof. (See Section 112.)

25

DESCRIPTION OF OTHER SECURITIES

We will set forth in the applicable prospectus supplement a description of any purchase contracts, units, depositary shares or warrants issued by us that may be offered and sold pursuant to this prospectus.

26

GLOBAL SECURITIES

Unless otherwise expressly stated or the context otherwise requires, under this caption “Global Securities,” references to “we,” “us,” “our,” “Sempra” and similar references mean Sempra excluding its consolidated entities and references to the “securities” mean the debt securities offered by this prospectus and the applicable prospectus supplement or free writing prospectus.

Book-Entry, Delivery and Form

Unless we indicate differently in any applicable prospectus supplement or free writing prospectus, the debt securities of each series initially will be issued in book-entry form and represented by one or more global debt securities, which we refer to as “global securities.” The global securities will be deposited with, or on behalf of, DTC and registered in the name of Cede & Co., the nominee of DTC. Unless and until it is exchanged for definitive debt securities in certificated form registered in the names of persons other than the depositary or its nominee, which we refer to as “certificated securities,” under the limited circumstances described below, a global security may not be transferred except as a whole by the depositary to its nominee or by the nominee to the depositary, or by the depositary or its nominee to a successor depositary or to a nominee of the successor depositary.

DTC has advised us that it is:

DTC holds securities that its participants deposit with DTC. DTC also facilitates the settlement among its participants of securities transactions, such as transfers and pledges, in deposited securities through electronic computerized book-entry changes in participants’ accounts, thereby eliminating the need for physical movement of securities certificates. “Direct participants” in DTC include securities brokers and dealers, including underwriters, banks, trust companies, clearing corporations and other organizations. Indirect access to the DTC system is also available to others, which we sometimes refer to as “indirect participants,” that clear transactions through or maintain a custodial relationship with a direct participant, either directly or indirectly. The rules applicable to DTC and its participants are on file with the SEC.

Purchases of securities under the DTC system must be made by or through direct participants, which will receive a credit for the securities on DTC’s records. The ownership interest of the actual purchaser of a security, which we sometimes refer to as a “beneficial owner,” is in turn recorded on the direct and indirect participants’ records. Beneficial owners of securities will not receive written confirmation from DTC of their purchases. However, beneficial owners are expected to receive written confirmations providing details of their transactions, as well as periodic statements of their holdings, from the direct or indirect participants (collectively, “participants”) through which they purchased securities. Transfers of ownership interests in global securities are to be accomplished by entries made on the books of participants acting on behalf of beneficial owners. Beneficial owners will not receive certificates representing their ownership interests in the global securities, except under the limited circumstances described below.

To facilitate subsequent transfers, all global securities deposited by direct participants with DTC will be registered in the name of DTC’s nominee, Cede & Co., or such other name as may be requested by an authorized representative of DTC. The deposit of securities with DTC and their registration in the name of Cede & Co. or

27

such other nominee will not change the beneficial ownership of the securities. DTC has no knowledge of the actual beneficial owners of the securities. DTC’s records reflect only the identity of the direct participants to whose accounts the securities are credited, which may or may not be the beneficial owners. The participants are responsible for keeping account of their holdings on behalf of their customers.

So long as the securities are in book-entry form, you will receive payments and may transfer securities only through the facilities of the depositary and its direct and indirect participants. We will maintain an office or agency for the applicable series of securities, where notices and demands in respect of the securities and the applicable indenture may be delivered to us and where certificated securities may be surrendered for payment, registration of transfer or exchange.

Conveyance of notices and other communications by DTC to direct participants, by direct participants to indirect participants and by direct participants and indirect participants to beneficial owners will be governed by arrangements among them, subject to any legal requirements in effect from time to time.

Redemption notices will be sent to DTC. If less than all of the global securities of a particular series are being redeemed, DTC’s practice is to determine by lot the amount of the interest of each direct participant in the global securities of such series to be redeemed.

In any case where a consent or vote may be required with respect to any securities, neither DTC nor Cede & Co. (or such other DTC nominee) will consent or vote with respect to the applicable global securities. Under its usual procedures, DTC will mail an omnibus proxy to us as soon as possible after the record date. The omnibus proxy assigns the consenting or voting rights of Cede & Co. (or such other DTC nominee) to those direct participants to whose accounts beneficial interests in such global securities are credited on the record date, identified in a listing attached to the omnibus proxy.

So long as securities are in book-entry form, we will make payments on those securities to the depositary or its nominee, as the registered owner of such securities, by wire transfer of immediately available funds. If certificated securities are issued under the limited circumstances described below, we will have the option of making payments by check mailed to the addresses of the persons entitled to payment as such addresses shall appear in the security register or by wire transfer at such places and to such accounts at such banking institutions in the United States as may be designated in writing to the applicable trustee at least 15 days before the applicable payment date by the persons entitled to payment.

DTC’s practice is to credit direct participants’ accounts upon DTC’s receipt of funds from us on the payment date in accordance with their respective holdings shown on DTC records. Payments by participants to beneficial owners will be governed by standing instructions and customary practices, as is the case with securities held for the account of customers in bearer form or registered in “street name.” Those payments will be the responsibility of participants and not of DTC or us, subject to any statutory or regulatory requirements in effect from time to time. Payment of the principal of, premium, if any, and interest on the global securities to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC, is our responsibility, disbursement of payments to direct participants is the responsibility of DTC, and disbursement of payments to the beneficial owners is the responsibility of direct and indirect participants.

Except under the limited circumstances described below, purchasers of securities will not be entitled to have securities registered in their names and will not receive physical delivery of securities. Accordingly, each beneficial owner must rely on the procedures of DTC and its participants to exercise any rights under the securities and the applicable indenture.

The laws of some jurisdictions may require that some purchasers of securities take physical delivery of securities in definitive form. Those laws may impair the ability to transfer or pledge beneficial interests in securities.

As noted above, beneficial owners of a particular series of securities generally will not receive certificates representing their ownership interests in those securities. However, if:

we will prepare and deliver certificated securities of such series in exchange for beneficial interests in the global securities. Any beneficial interest in a global security that is exchangeable under the circumstances described in the preceding sentence will be exchangeable for certificated securities of such series in definitive form registered in the names that the depositary directs. It is expected that these directions will be based upon directions received by the depositary from its participants with respect to ownership of beneficial interests in the global securities.

Euroclear and Clearstream

If so provided in the applicable prospectus supplement, you may hold interests in a global security through Clearstream Banking S.A., which we refer to as “Clearstream,” or Euroclear Bank S.A./N.V., as operator of the Euroclear System, which we refer to as “Euroclear,” either directly if you are a participant in Clearstream or Euroclear or indirectly through organizations which are participants in Clearstream or Euroclear. Clearstream and Euroclear will hold interests on behalf of their respective participants through customers’ securities accounts in the names of Clearstream and Euroclear, respectively, on the books of their respective U.S. depositaries, which in turn will hold such interests in customers’ securities accounts in such depositaries’ names on DTC’s books.

Clearstream and Euroclear are securities clearance systems in Europe. Clearstream and Euroclear hold securities for their respective participating organizations and facilitate the clearance and settlement of securities transactions between those participants through electronic book-entry changes in their accounts, thereby eliminating the need for physical movement of certificates.

Payments, deliveries, transfers, exchanges, notices and other matters relating to beneficial interests in global securities owned through Euroclear or Clearstream must comply with the rules and procedures of those systems. Transactions between participants in Euroclear or Clearstream, on one hand, and other participants in DTC, on the other hand, are also subject to DTC’s rules and procedures.

Investors will be able to make and receive through Euroclear and Clearstream payments, deliveries, transfers and other transactions involving any beneficial interests in global securities held through those systems only on days when those systems are open for business. Those systems may not be open for business on days when banks, brokers and other institutions are open for business in the United States.

Cross-market transfers between participants in DTC, on the one hand, and participants in Euroclear or Clearstream, on the other hand, will be effected through DTC in accordance with the DTC’s rules on behalf of Euroclear or Clearstream, as the case may be, by their respective U.S. depositaries; however, such cross-market transactions will require delivery of instructions to Euroclear or Clearstream, as the case may be, by the counterparty in such system in accordance with the rules and procedures and within the established deadlines (European time) of such system. Euroclear or Clearstream, as the case may be, will, if the transaction meets its settlement requirements, deliver instructions to its U.S. depositary to take action to effect final settlement on its

29

behalf by delivering or receiving interests in the global securities through DTC, and making or receiving payment in accordance with normal procedures for same-day fund settlement. Participants in Euroclear or Clearstream may not deliver instructions directly to their respective U.S. depositaries.

Due to time zone differences, the securities accounts of a participant in Euroclear or Clearstream purchasing an interest in a global security from a direct participant in DTC will be credited, and any such crediting will be reported to the relevant participant in Euroclear or Clearstream, during the securities settlement processing day (which must be a business day for Euroclear or Clearstream) immediately following the settlement date of DTC. Cash received in Euroclear or Clearstream as a result of sales of interests in a global security by or through a participant in Euroclear or Clearstream to a direct participant in DTC will be received with value on the settlement date of DTC but will be available in the relevant Euroclear or Clearstream cash account only as of the business day for Euroclear or Clearstream following DTC’s settlement date.
