NiSource (NYSE: NI) expands $2.5B revolver and extends maturity to 2030

Rhea-AI Filing Summary

NiSource Inc. entered into a Seventh Amended and Restated Revolving Credit Agreement that increases its revolving credit facility to $2.5 billion and extends its termination date to December 11, 2030. The facility size rose by $650 million compared with the prior agreement, providing a larger committed borrowing capacity.

The agreement also raises the portion available for standby letters of credit by $25 million to $175 million and increases certain dollar and materiality thresholds tied to permitted liens, cross-defaults and the definition of Material Subsidiary. In addition, it removes provisions that linked the Applicable Rate to environmental, social and governance key performance indicators. Other terms, including representations, covenants and events of default, substantially carry over from the prior facility.

Insights

Corporate credit analyst

NiSource ups its revolving credit capacity to $2.5B and pushes maturity to 2030.

NiSource has replaced its prior revolving credit facility with a Seventh Amended and Restated agreement that sets total commitments at $2.5 billion, an increase of $650 million. The termination date moves from February 18, 2027 to December 11, 2030, which lengthens access to this committed bank liquidity.

The agreement also increases the sublimit for standby letters of credit to $175 million and raises certain materiality thresholds for items such as permitted liens and cross-defaults, which can modestly affect when covenant tests are triggered. Provisions that could have adjusted the Applicable Rate based on environmental, social and governance key performance indicators have been eliminated, simplifying pricing mechanics.

Overall, this action refreshes NiSource’s core bank funding backstop with a larger size and later maturity while keeping the existing covenant framework largely intact. Future disclosures in company filings may provide more detail on any pricing differences under the new facility and how NiSource uses the expanded capacity over the life of the agreement through 2030.
