NiSource (NI) recently completed a US$750 million fixed to floating rate note offering due in 2057, a long dated financing move that highlights its capital raising plans and long term funding approach.

Despite completing this long dated US$750 million note issue, NiSource’s recent share price performance has been soft, with the stock down 12.92% on a 30 day share price return and 14.37% on a 90 day share price return. However, the 3 year total shareholder return of 66.83% and 5 year total shareholder return of 94.01% still point to a much stronger longer term outcome.

Another View on NiSource’s Valuation

The first narrative suggests NiSource is about 18.8% undervalued at $40.65 versus a fair value of $50.03. On simple P/E, the picture is less one sided. NiSource trades on 21.5x earnings, above the global Integrated Utilities average of 18.4x but below a peer average of 32x and a fair ratio of 23.2x. That mix points to some valuation support, yet also leaves less room if expectations slip. Which lens do you trust more when pricing a regulated utility with steady but moderate growth?
