Credit Markets Analyst

Material renewal of unsecured revolving credit lines extends liquidity to 2030 with standard covenants and flexible rate options.

DTE Energy, DTE Electric, and DTE Gas each entered sixth amended and restated five‑year unsecured revolving credit agreements. Commitments total $1.5B for **DTE Energy**, $1.0B for **DTE Electric**, and $300M for **DTE Gas**. Each facility matures on October 22, 2030 and includes two one‑year extension options. Borrowings accrue interest at either a Base Rate or Adjusted Term SOFR, in each case plus an Applicable Margin.

The facilities are unsecured and include customary covenants. Debt‑to‑capitalization must not exceed 0.70% to 1 for **DTE Energy** and 0.65% to 1 for **DTE Electric** and **DTE Gas**. Proceeds may be used for general corporate purposes. These lines function as committed backstop liquidity, supporting working capital, refinancing flexibility, and timing of cash flows without pledging collateral.

Key watch items: any future amendments affecting size, tenor, pricing, or covenants; actual usage levels versus commitments; and compliance with the stated debt‑to‑capitalization tests. The next structural milestone is the stated maturity on October 22, 2030, with potential one‑year extensions available if exercised.
