Committed Lines of Credit
At December 31, 2024, Sempra had an aggregate capacity of $9.9 billion under seven primary committed lines of credit, which provide liquidity and support our commercial paper programs. Because our commercial paper programs are supported by some of these lines of credit, we reflect the amount of commercial paper outstanding, before reductions of any unamortized discounts, and any letters of credit outstanding as a reduction to the available unused credit capacity in the following table.

The principal terms of Sempra’s, SDG&E’s and SoCalGas’ lines of credit reflected in the table above include the following:
▪Each facility has a syndicate of 23 lenders. No single lender has greater than a 6% share in any facility.
▪Sempra’s, SDG&E’s and SoCalGas’ facilities provide for the issuance of $200 million, $100 million and $150 million, respectively, of letters of credit. Subject to obtaining commitments from existing or new lenders and satisfaction of other specified conditions, Sempra, SDG&E and SoCalGas each has the right to increase its letter of credit commitment to up to $500 million, $250 million and $250 million, respectively.
▪Borrowings bear interest at a benchmark rate plus a margin that varies with the borrower’s credit rating.
▪Each borrower must maintain a ratio of indebtedness to total capitalization (as defined in each of the applicable credit facilities) of no more than 65% at the end of each quarter. At December 31, 2024, each Registrant was in compliance with this ratio under its respective credit facility.
SI Partners and IEnova have three combined lines of credit, reflected in the table above, that require borrowings to be issued in U.S. dollars only and include the following principal terms:
▪Borrowings on the $500 million revolving credit facility bear interest at a per annum rate equal to term SOFR plus 80 bps (including a credit adjustment spread).
▪The $1.0 billion facility provides for borrowings of up to $1.0 billion through a syndicate of 12 lenders available to SI Partners and up to $910 million through a syndicate of 11 lenders available to IEnova, subject to a combined borrowing limit of $1.0 billion. This facility:
◦Charges interest on borrowings at a benchmark rate plus a margin that varies with SI Partners’ credit rating (plus a term SOFR credit adjustment spread of 10 bps in all tenors).
◦Provides for issuance of up to $200 million of letters of credit, subject to a combined letter of credit commitment of $200 million, which can be issued in U.S. dollars or Mexican pesos, and which reduces available unused credit.
◦Includes a $100 million swingline loan sub-limit, whereby any outstanding amounts would reduce available unused credit. No swingline loan borrowings were outstanding at December 31, 2024.
◦Gives either SI Partners or IEnova the right to increase the total facility to $1.5 billion, subject to lender approval, with borrowings of up to $1.5 billion through a syndicate of 12 lenders available to SI Partners and up to $1,365 million through a syndicate of 11 lenders available to IEnova.
▪Borrowings on the $1.5 billion revolving credit facility, with borrowings of up to $1.5 billion through a syndicate of 12 lenders available to SI Partners and up to $1,365 million through a syndicate of 11 lenders available to IEnova, subject to a combined borrowing limit of $1.5 billion, bear interest at a per annum rate equal to term SOFR plus 90 bps (including a credit adjustment spread).
Additionally, the three lines of credit that are shared by SI Partners and IEnova require that SI Partners maintain a ratio of consolidated adjusted net indebtedness to consolidated earnings before interest, taxes, depreciation and amortization (as defined in each credit facility) of no more than 5.25 to 1.00 at the end of each quarter. At December 31, 2024, SI Partners was in compliance with this ratio.
Port Arthur LNG has a working capital facility agreement, reflected in the table above, that permits borrowings of up to $200 million, which bear interest by reference to term SOFR plus the applicable margin and a credit adjustment spread. The credit facility also provides for the issuance of up to $200 million of letters of credit, which reduces available unused credit.
Uncommitted Line of Credit
ECA LNG Phase 1 has an uncommitted line of credit with an aggregate capacity of $100 million that expires in August 2026. Borrowings are generally used for working capital requirements and can be in U.S. dollars or Mexican pesos. At December 31, 2024, ECA LNG Phase 1 had outstanding borrowings of $8 million, before reductions of any unamortized discounts, in Mexican pesos that bear interest at a variable rate based on the 28-day Interbank Equilibrium Interest Rate plus 154 bps. Borrowings made in U.S. dollars bear interest at a variable rate based on the one-month or three-month SOFR plus 164 bps and a credit adjustment spread of 10 bps.
Uncommitted Letters of Credit
Outside of our domestic and foreign credit facilities, we have bilateral unsecured standby letter of credit capacity with select lenders that is uncommitted and supported by reimbursement agreements. At December 31, 2024, we had $497 million in standby letters of credit outstanding under these agreements.

Term Loan
In May 2024, SoCalGas entered into a $500 million, 364-day term loan facility with a maturity date of May 22, 2025, and in December 2024, SoCalGas increased the amount of the term loan to $700 million. At December 31, 2024, SoCalGas had borrowed the full $700 million then available under the term loan, net of negligible debt issuance costs, which is included in Short-Term Debt on SoCalGas’ Balance Sheet. SoCalGas may request a further increase in the term loan facility of up to $300 million prior to the maturity date, subject to lender approval. The outstanding borrowings bear interest at a per annum rate equal to term SOFR, plus 80 bps and a credit adjustment spread of 10 bps. SoCalGas used the proceeds to repay commercial paper and for other general corporate purposes.

First Mortgage Bonds
SDG&E and SoCalGas issue first mortgage bonds secured by liens on their respective utility plant assets. SDG&E and SoCalGas may issue additional first mortgage bonds if in compliance with the provisions of their bond agreements (indentures). These indentures require, among other things, the satisfaction of pro forma earnings-coverage tests on first mortgage bond interest and the availability of sufficient mortgaged property to support the additional bonds, after giving effect to prior bond redemptions. The most restrictive of these tests (the property test) would permit the issuance, subject to CPUC authorization, of additional first mortgage bonds of $8.8 billion at SDG&E and $1.6 billion at SoCalGas at December 31, 2024.
SDG&E
In March 2024, SDG&E issued $600 million aggregate principal amount of 5.55% first mortgage bonds due in full upon maturity on April 15, 2054 and received proceeds of $587 million (net of debt discount, underwriting discounts and debt issuance costs of $13 million). The first mortgage bonds are redeemable prior to maturity, subject to their terms, and in certain circumstances subject to make-whole provisions. SDG&E used the net proceeds to repay commercial paper and for other general corporate purposes.
SoCalGas
In March 2024, SoCalGas issued $500 million aggregate principal amount of 5.60% first mortgage bonds due in full upon maturity on April 1, 2054 and received proceeds of $491 million (net of debt discount, underwriting discounts and debt issuance costs of $9 million). The first mortgage bonds are redeemable prior to maturity, subject to their terms, and in certain circumstances subject to make-whole provisions. SoCalGas used the net proceeds to repay outstanding indebtedness and for other general corporate purposes.
In August 2024, SoCalGas issued $600 million aggregate principal amount of 5.05% first mortgage bonds due in full upon maturity on September 1, 2034 and received proceeds of $592 million (net of debt discount, underwriting discounts and debt issuance costs of $8 million). The first mortgage bonds are redeemable prior to maturity, subject to their terms, and in certain circumstances subject to make-whole provisions. SoCalGas used the net proceeds to repay outstanding indebtedness and for other general corporate purposes.

Interest is payable on the notes semi-annually in arrears on April 1 and October 1 of each year, beginning on October 1, 2024 (for the March 2024 and May 2024 issuances) or April 1, 2025 (for the September 2024 and November 2024 issuances).
We may redeem some or all of the notes before their maturity, as follows:
▪in whole or in part, (i) on any day in the period commencing on the date falling 90 days prior to, and ending on and including October 1, 2029 (for the March 2024 and May 2024 issuances), October 1, 2034 (for the September 2024 issuance), April 1, 2030 (for the $400 million November 2024 issuance), and April 1, 2035 (for the $600 million November 2024 issuance), and (ii) after those respective dates, on any interest payment date, at a redemption price in cash equal to 100% of the principal amount of the notes being redeemed, plus, subject to the terms of the notes, accrued and unpaid interest on the notes to be redeemed to, but excluding, the redemption date;
▪in whole but not in part, at any time following the occurrence and during the continuance of a tax event (as defined in the notes) at a redemption price in cash equal to 100% of the principal amount of the notes, plus, subject to the terms of the notes, accrued and unpaid interest on the notes to, but excluding, the redemption date; and
▪in whole but not in part, at any time following the occurrence and during the continuance of a rating agency event (as defined in the notes) at a redemption price in cash equal to 102% of the principal amount of the notes, plus, subject to the terms of the notes, accrued and unpaid interest on the notes to, but excluding, the redemption date.
The notes described above are unsecured obligations and rank junior and subordinate in right of payment to our existing and future senior indebtedness. The notes rank equally in right of payment with each other and with our existing 4.125% fixed-to-fixed reset rate junior subordinated notes due 2052 and 5.75% junior subordinated notes due 2079 and with any future unsecured indebtedness that we may incur if the terms of such indebtedness provide that it ranks equally with the notes in right of payment. The notes are effectively subordinated in right of payment to any secured indebtedness we have incurred or may incur (to the extent of the value of the collateral securing such secured indebtedness) and to all existing and future indebtedness and other liabilities and any preferred equity of our subsidiaries.
We used, or plan to use, the proceeds from the offerings for general corporate purposes, including repayment of commercial paper and other indebtedness.

IEnova and TotalEnergies SE have provided guarantees for repayment of the loans plus accrued and unpaid interest of 83.4% and 16.6%, respectively. At December 31, 2024 and 2023, $1.1 billion and $832 million, respectively, of borrowings from external lenders were outstanding under the loan agreement, with a weighted-average interest rate of 7.29% and 8.31%, respectively.
Port Arthur LNG. Port Arthur LNG has a seven-year term loan facility agreement with a syndicate of lenders that matures on March 20, 2030, for an aggregate principal amount of approximately $6.8 billion. At December 31, 2024 and 2023, $1.1 billion and $258 million, respectively, of borrowings were outstanding under the loan agreement, with an all-in weighted-average interest rate of 5.33% and 5.81%, respectively.
