SIERRA PACIFIC POWER CO 8-K

What Happened

• On March 9, 2026, Sierra Pacific Power Company announced the completion of a $600 million offering of 6.375% Fixed-to-Fixed Reset Rate Junior Subordinated Notes (SPPC JSN Series 2026A) due September 15, 2056. The notes were sold pursuant to an Underwriting Agreement dated March 5, 2026, and issued under an indenture with The Bank of New York Mellon Trust Company, N.A. as trustee.

Key Details

• Issue size and coupon: $600 million principal; 6.375% interest from March 9, 2026 to (but excluding) September 15, 2031 (First Reset Date).
• Reset mechanics: From the First Reset Date and each Reset Period thereafter, rate = five‑year U.S. Treasury rate (on the Reset Interest Determination Date) + 2.638%, but never below 6.375%. Interest payable semiannually on March 15 and September 15, beginning September 15, 2026.
• Use of proceeds: Approximately $400 million to repay Series U general and refunding mortgage securities (2.60% coupon) maturing May 1, 2026; remaining proceeds for capital expenditures and general corporate purposes.
• Credit and structure: Notes are unsecured, junior subordinated obligations (rank behind the company’s senior debt). Company has customary underwriter indemnities; limited redemption rights include windows around the First Reset Date and special redemptions for a Tax Event or Rating Agency Event.

Why It Matters

• This offering materially refinances near‑term debt: $400M will retire Series U mortgage securities maturing in May 2026, helping manage near‑term maturities.
• Cost of debt has increased: the new notes carry a much higher initial coupon (6.375%) than the retired 2.60% Series U, so interest expense will rise unless the company redeems or refinances later under more favorable terms.
• Subordination and long maturity: because the notes are junior and unsecured and mature in 2056, they are lower priority than senior debt—important for creditors and investors assessing the company’s capital structure and risk profile.
