Wisconsin Public Service Corp Announces $300M Senior Notes Offering

What Happened
On August 10, 2026, Wisconsin Public Service Corporation entered into an Underwriting Agreement to issue and sell $300,000,000 aggregate principal amount of Senior Notes, 6.05% Series due August 15, 2056. The offering is being made in a registered public offering pursuant to a Form S-3 registration statement (Registration No. 333-279582). The transaction was disclosed in the company’s Form 8-K under Item 8.01 (Other Events).

Key Details

• Amount: $300,000,000 aggregate principal amount of Senior Notes.
• Coupon: 6.05% interest.
• Maturity: August 15, 2056 (long-term fixed-rate debt).
• Offering status: Being issued and sold in a registered offering under the Securities Act via Form S-3 (Reg. No. 333-279582); agreement entered Aug 10, 2026.

Why It Matters
This filing reports a material issuance of long-term fixed-rate debt for the company: $300 million at a 6.05% coupon maturing in 2056. That increases the company’s long-term obligations and establishes a fixed interest expense tied to these notes. The 8-K does not disclose the use of proceeds, final pricing/settlement details, or additional economic terms beyond the coupon and maturity; investors should look for subsequent filings that provide closing details, use of proceeds, and any related credit-rating or covenant disclosures.
