The accelerating transition towards decarbonization and electrification presents a clear emerging threat to NiSource. This trend is driven by increasingly stringent environmental regulations, mandates for greenhouse gas emission reductions, and the growing economic viability and consumer adoption of electric alternatives (like heat pumps) and distributed renewable energy sources (like rooftop solar and battery storage). These shifts risk reducing demand for natural gas, potentially stranding existing infrastructure assets within NiSource's substantial natural gas distribution business, and diminishing reliance on traditional grid-supplied electricity, akin to how streaming services disrupted traditional media consumption models.

NiSource Inc. (NI) primarily operates in two main addressable markets within the United States: natural gas distribution and electric services. The company serves approximately 3.5 million natural gas customers and 500,000 electric customers across six states: Indiana, Kentucky, Maryland, Ohio, Pennsylvania, and Virginia.

For its natural gas distribution services, the U.S. market size was valued at approximately $174.7 billion in 2024 and is projected to reach $222.5 billion in 2025. Another estimate indicates the U.S. natural gas distribution market was valued at $170.0 billion in 2024, with an expected increase to $186.0 billion by 2032, growing at a CAGR of 1.0% from 2025–2032. Globally, the natural gas distribution market was valued at $908.12 billion in 2024 and is expected to grow to $967.58 billion in 2025. NiSource's natural gas utilities provide service in Indiana, Kentucky, Maryland, Ohio, Pennsylvania, and Virginia.

Regarding its electric services, which include generation, transmission, and distribution, NiSource primarily provides these to customers in northern Indiana. The U.S. electric distribution utility market was estimated at $379.1 billion in 2023, with a projected growth to over $686.7 billion by 2032, at a CAGR of 6.7% from 2024 to 2032. More specifically, the U.S. electricity transmission and distribution market was valued at $82.96 billion in 2022 and is projected to grow at a CAGR of 2.95% during the forecast period. Another source valued the U.S. electric power transmission and distribution market at $89.9 billion in 2024, expecting it to increase to $110.4 billion by 2032.

NiSource (NI) is expected to drive future revenue growth over the next 2-3 years through several key initiatives and investments:

1. Robust Capital Expenditure and Rate Base Growth: NiSource has a substantial capital expenditure plan, with a consolidated total of $28.0 billion planned over the next five years. This investment is projected to drive an 8%-10% rate base growth from 2026 to 2030. These expenditures are primarily aimed at modernizing and replacing existing utility infrastructure across both its natural gas and electric systems.
2. Strategic Investments in Data Center Infrastructure: A significant new driver for NiSource is its strategic capital investment, approximately $7.0 billion, related to data centers. This includes developing new infrastructure, such as combined cycle gas plants and battery storage, to meet the escalating power demands of hyperscale and enterprise data centers, particularly in NIPSCO's Indiana service territory. These investments are underpinned by long-term, fixed-rate contracts with investment-grade customers.
3. Renewable Energy Transition and Grid Modernization: NiSource is actively investing in the transition to cleaner energy and modernizing its electric grid. The company plans to retire all its coal-fired generating units by 2028 and aims to achieve net-zero greenhouse gas emissions for Scope 1 and 2 by 2040. This transition involves substantial investments in renewable energy sources, such as solar, and advanced metering infrastructure, all of which contribute to the company's rate base and subsequent revenue growth.
4. Favorable Regulatory Recovery and Mechanisms: The company's revenue growth is significantly supported by constructive regulatory relationships and mechanisms that enable the recovery of its capital investments. NiSource has a track record of securing regulatory approvals for revenue recovery, which helps minimize lag and enhance cash flow, ensuring that its substantial infrastructure investments translate into increased rates and, consequently, higher revenue.
