NiSource Reports 18.3% Revenue Growth to $1.273 Billion in Latest Quarter

NiSource Inc. reported significant financial growth in its latest quarterly filing for the period ending September 30, 2025. The company achieved total operating revenues of $1.273 billion, a 18.3% increase from $1.076 billion in the same quarter of 2024. This growth was driven primarily by a rise in customer revenues, which reached $1.240 billion, up from $1.046 billion year-over-year. Net income attributable to NiSource also saw an increase, rising to $94.7 million from $85.7 million, resulting in earnings per share of $0.20, compared to $0.19 in the prior year.

In terms of operational performance, NiSource's total operating expenses increased to $975.6 million from $858 million, reflecting higher costs associated with energy, operations, and maintenance. The cost of energy alone rose to $193.6 million from $165.9 million, while operation and maintenance expenses increased to $401.1 million from $357.4 million. Despite these rising costs, the company reported an operating income of $297.5 million, up from $218.3 million in the previous year, indicating improved operational efficiency.

Strategically, NiSource has made significant advancements in its energy transition initiatives, including the execution of a Data Center Contract with a large publicly traded company. This contract, which is subject to regulatory approval, will see NiSource provide up to 2,400 MW of electricity to the customer by 2032, necessitating the construction of new generation assets. The company is also actively pursuing additional data center opportunities, which are expected to enhance its local tax base and diversify its employment base in Indiana.

As of September 30, 2025, NiSource reported a total of 2,404,775 customers across its Columbia Operations and NIPSCO Operations segments, reflecting a growth of approximately 14,503 customers compared to the previous year. The company also noted an increase in its employee headcount, which is essential for supporting its expanding operations and strategic initiatives. Furthermore, NiSource's total assets increased to $34.4 billion from $31.8 billion at the end of 2024, bolstered by ongoing investments in infrastructure and renewable energy projects.

Looking ahead, NiSource remains focused on its long-term growth strategy, which includes significant capital investments estimated between $4.0 billion and $4.3 billion for 2025. The company anticipates that these investments will support its infrastructure modernization efforts and facilitate the transition to cleaner energy sources. However, management acknowledges potential risks associated with construction delays, cost overruns, and regulatory changes that could impact the execution of its strategic plans.
