The principal terms of our debt arrangements are described below and in Note 7 of the Notes to Consolidated Financial Statements in the Annual Report.
SHORT-TERM DEBT
Committed Lines of Credit
At March 31, 2026, Sempra has an aggregate capacity of $10.2 billion under eight 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.

Sempra, SDG&E and SoCalGas each 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 March 31, 2026, each Registrant was in compliance with this ratio under its respective credit facility.
The three lines of credit that are shared by SI Partners and its subsidiary, 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 March 31, 2026, SI Partners was in compliance with this ratio.
Additionally, the three lines of credit that are shared by SI Partners and IEnova and the Port Arthur LNG I and Port Arthur LNG II credit facilities are included in the disposal group that is classified as held for sale that we discuss in Note 6 but remain legally accessible and a source of available credit to Sempra Infrastructure until the planned sale of a portion of our equity interest in SI Partners closes.
Uncommitted Line of Credit
ECA LNG Phase 1, which is included in the disposal group that is classified as held for sale, 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 March 31, 2026, ECA LNG Phase 1 has outstanding borrowings of $13 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 unsecured standby letter of credit capacity with select lenders that is uncommitted and supported by reimbursement agreements. At March 31, 2026, we have $202 million in standby letters of credit outstanding under these agreements.

IEnova and TotalEnergies SE have provided guarantees for repayment of the loan of up to $1,226 million and $305 million, respectively, plus accrued and unpaid interest.
