$WELPPForm 424B5Filed Aug 19, 2026, 9:00 AM ET0001104659-26-098603Original filing

Wisconsin Electric Power Company, a subsidiary of WEC Energy Group, filed a preliminary prospectus supplement for a public offering of 5.10% debentures due June 15, 2036. The new debentures reopen the same series as the $400 million of 5.10% debentures issued June 4, 2026, with the offering size and price to be set at pricing. Proceeds will repay short-term debt and fund general corporate purposes. At August 17, 2026, short-term debt stood at $298.8 million at a 3.89% weighted average rate with an average life under 30 days, so the deal effectively terms out commercial paper-style borrowings into ten-year fixed-rate debt.
