NiSource pairs a regulated utility base with a credible earnings runway and data center upside, but heavy capital spending and rising debt keep the risk profile elevated. The stock looks attractive for growth-oriented utility investors, not for those seeking a low-risk balance sheet story.
NiSource Inc. (NI) offers a regulated utility growth profile with a credible medium-term earnings runway, but its heavy capital needs and rising debt prevent the stock from qualifying as a low-risk bargain. The investment thesis rests on three facts: management reaffirmed 2026 adjusted EPS guidance of $2.02 to $2.07, projected consolidated adjusted EPS growth of 9% to 10% annually from 2026 through 2033, and secured Amazon (AMZN) and Alphabet (GOOGL) data center agreements that are expected to provide approximately $1.4B of bill reductions to existing customers.
The core business remains defensive. NI operates regulated gas and electric utilities across six states, serving approximately 3.8M customers. Its 2025 income statement showed $6.64B of revenue, $1.83B of operating income, and $929.5M of net income. Operating margin reached 27.6%, up from 20.6% in 2021.
The tradeoff is financial intensity. Debt rose to $17.57B by June 30, 2026, while cash stood at only $70M. Annual free cash flow remained negative at $420M in 2025 because capital expenditures exceeded operating cash flow. For a moderate-risk investor, NI is best viewed as a regulated growth holding rather than a pure income or balance-sheet safety play.
At a quoted price of $41.49, the shares trade below the 52-week high of $48.88 and below the 200-day moving average of $44.86. The combination of visible rate-base growth and data center optionality supports upside, while the 1.7 debt-to-equity ratio and 0.7 current ratio justify a measured position size.
NiSource Inc. (NI), headquartered in Merrillville, Indiana, is a regulated natural gas and electric utility holding company founded in 1847. The company employs approximately 7,668 people and operates through Columbia Operations and NIPSCO Operations.
The company earns substantially all of its revenue and earnings from regulated utility operations. That structure provides local service territories, long-lived infrastructure and a framework for recovering prudent investment through rates and regulatory mechanisms. It also makes regulatory decisions, customer affordability and financing costs central to the equity story.
NI's 2026 to 2030 capital plan totals $28.6B, including $21.0B of base investment and $7.6B for strategic data center infrastructure. Management said the plan supports consolidated rate-base growth of 9% to 11% from 2026 through 2033.
The gas business is the larger operating platform. In the 2023 segment data, Gas Distribution Operations generated $3.73B of revenue, or 67.6% of the $5.52B total. Electric Operations generated $1.79B, or 32.4%. The historical mix gives NI a meaningful gas bias, even as the company expands its electric and data center platform.
Columbia Operations includes approximately 37,300 miles of gas distribution main pipeline and 310 miles of transmission main pipeline. The segment serves a broad geographic footprint, which spreads exposure across five states but also creates multiple regulatory calendars and operating requirements.
NIPSCO combines gas distribution with electric generation, transmission and distribution in northern Indiana. Its electric business serves approximately 0.5M customers, operates about 3,000 circuit miles of transmission, and owns 65 transmission and 240 distribution substations.
The segment mix is shifting toward electric load growth. Amazon and Alphabet agreements have received Indiana Utility Regulatory Commission approval, while Alphabet's load is scheduled to ramp to full capacity by 2030. Management also cited 3 gigawatts of active strategic negotiations and approximately 2 gigawatts of additional potential customers behind those discussions.

NI's most important growth offering is its GenCo data center model. This is not a conventional consumer product. It is a regulated power and infrastructure arrangement designed to serve large-load customers while assigning specific costs and benefits within the regulatory framework.
The flagship contracts with Amazon and Alphabet are expected to generate approximately $1.4B of bill reductions for existing NIPSCO electric customers over their contract terms. Management said the average residential customer could receive up to $124 of annual benefit, with savings beginning as early as the fourth quarter of 2026.
The model addresses one of the industry's hardest problems: adding large electricity demand without placing the entire cost burden on existing residential customers. NI's agreements also create a path for $7.6B of strategic data center infrastructure investment within the 2026 to 2030 plan.
The near-term evidence is tangible. The IURC approved the original Amazon special contract, related power purchase agreement and supporting generation resources in June 2026. The Alphabet agreement received approval in July 2026. The remaining investment case depends on execution, construction, load ramp and cost recovery, all of which are directly connected to the approved agreements and the stated 2030 full-capacity target.
NI's durable advantage comes from regulated service territories rather than proprietary hardware. The 10-K describes gas and electric operations protected by local infrastructure, regulatory oversight and high capital barriers. Competitors cannot simply duplicate 37,300 miles of Columbia gas distribution or NIPSCO's northern Indiana electric network.
The company is also applying technology to operating efficiency. Management cited Project Apollo, AI-enabled enterprise data access, speech analytics and storm-response tools. These initiatives are tied to standardizing work, improving visibility and reducing waste rather than selling software to outside customers.
Management identified more than $40M of cost-optimization initiatives across the business. The stated sources include process improvements, technology-enabled efficiencies and other actions intended to reduce costs while maintaining service quality. That amount is modest relative to NI's $28.6B capital program, but it can support earnings execution if the savings reach customer rate structures.
The strongest strategic advantage is the combination of regulated infrastructure and new electric demand. The gas network provides scale and stability, while data centers add a growth vector that many traditional gas-heavy utilities do not possess.
NI's physical operating footprint is substantial. Columbia Operations includes 37,300 miles of distribution main pipeline and 310 miles of transmission main pipeline. NIPSCO Gas adds 18,100 miles of distribution main pipeline and 720 miles of transmission main pipeline in northern Indiana.
NIPSCO Electric operates approximately 3,000 transmission circuit miles, 65 transmission substations, 240 distribution substations and roughly 312,500 poles. Its generation portfolio includes two hydroelectric facilities, a combined-cycle gas turbine, two coal facilities and eight renewable generation facilities, three of which entered service in 2025.
The company also holds power purchase agreements providing approximately 1,200 megawatts of capacity, with contracts expiring between 2038 and 2045. The Michigan City coal facility is scheduled for retirement by the end of 2028, while federal emergency orders required continued operation of the R.M. Schahfer coal plant through March 2026 and again in June 2026.
Operations faced elevated weather pressure in 2026. Management cited a record number of tornadoes, increased outages and higher storm-related costs. Q2 2026 also included $21.4M of workplace continuity costs. These items show how labor availability, severe weather and regulatory reliability requirements can raise operating costs even when the underlying network remains intact.
NI operates in a regulated utility market shaped by infrastructure replacement, electrification and large-load demand. The company's own identified investment opportunity is the clearest market indicator: its 2026 to 2030 plan calls for $28.6B of capital deployment, with $21.0B directed to base business investment and $7.6B to data center infrastructure.
Large-load demand is moving from a talking point into contracted activity. NI has signed approximately 4 gigawatts of data center capacity, maintains 3 gigawatts in active strategic negotiations and sees approximately 2 gigawatts of additional potential customers. Management also said the company is examining ways to expand beyond its current 9 gigawatt pipeline.
The market's constraint is affordability. NI reported that Indiana residential electric bills declined year over year in the 2026 survey, with renewable generation and cost efficiencies cited as contributors. The Amazon and Alphabet agreements are designed to reinforce that outcome through approximately $1.4B of customer bill reductions.
This creates a favorable but demanding market structure. Utilities with approved projects and constructive regulators can grow rate base, while utilities that fail to demonstrate customer benefits face slower recovery and political pressure.

NI serves a diversified customer base across residential, commercial and industrial users. Columbia Operations serves approximately 2.4M customers, NIPSCO Gas serves approximately 0.9M, and NIPSCO Electric serves approximately 0.5M. The geographic footprint spans Ohio, Pennsylvania, Virginia, Kentucky, Maryland and Indiana.
Gas customers can purchase supply from third-party producers and marketers while using NI's distribution and transportation network. As of December 31, 2025, third-party programs covered 34.9% of Columbia residential customers and 41.1% of Columbia commercial customers. At NIPSCO Gas, the comparable figures were 6.8% and 18.5%.
The data center customer profile is different. Amazon and Alphabet represent concentrated, high-load counterparties with the ability to support major infrastructure investment. Their contracts can improve utilization and spread fixed network costs, but the concentration also makes contract structure, load ramp and cost recovery important to shareholder outcomes.
Customer affordability remains a central operating metric. Management's statement that the GenCo model can return $1.4B to existing customers gives the growth strategy a direct customer benefit rather than treating large-load expansion as a purely corporate earnings project.
The relevant public-market peers include Atmos Energy (ATO), CMS Energy (CMS), CenterPoint Energy (CNP), Dominion Energy (D), Duke Energy (DUK), DTE Energy (DTE), Xcel Energy (XEL), OGE Energy (OGE) and Southern Company (SO). NI competes with these companies for investor capital and for regulatory execution, even though its local utility territories are generally protected from direct retail competition.
Operational competition is more specific. NI's 10-K identifies investor-owned, municipal and cooperative electric utilities, regulated and unregulated gas pipelines, propane and fuel oil as competitive alternatives. The company cites customer preference for natural gas as a positioning advantage in its gas markets.
NI's distinguishing feature is its combination of a gas-heavy regulated footprint and a growing electric load platform. Atmos Energy (ATO) offers a more concentrated regulated gas comparison, while CMS Energy (CMS), DTE Energy (DTE) and CenterPoint Energy (CNP) provide closer multi-utility comparisons. NI adds data center agreements and a 9 gigawatt pipeline to that conventional utility profile.
The competitive weakness is leverage. NI ended 2025 with $15.97B of debt and a 1.69 debt-to-equity ratio. That makes financing discipline more important than it is for a lightly levered utility and limits how aggressively the company can pursue incremental projects without corresponding regulatory recovery and capital support.
The most important macro forces for NI are electricity demand, customer affordability, regulatory policy and system reliability. Management linked its opportunity to economic development, manufacturing reshoring and data center construction across the service territories. Virginia projects alone were cited as representing more than $1.7B of planned investment and over 1,300 new jobs.
Reliability policy is also material. The federal government issued orders requiring continued operation of the R.M. Schahfer coal facility during energy emergencies in the MISO North and Central regions. NI is pursuing recovery of associated compliance costs through a Federal Energy Regulatory Commission Section 205 filing.
Regulatory outcomes vary by jurisdiction. NI received Ohio approval for infrastructure and safety-related tracker mechanisms and filed Virginia and Kentucky rate cases, with decisions expected in the first half of 2027. In Indiana, the IURC encouraged continued gas investment while requiring stronger demonstrations of project-specific customer benefits.
Severe weather adds an operating and political layer. Management described 2026 as an unusually active tornado year, while Q2 operating results reflected elevated storm activity and higher operating and maintenance costs. For NI, the macro backdrop is favorable for infrastructure demand but unforgiving when customer bills or reliability performance deteriorate.
Debt climbed to $17.57B by June 30, 2026 while cash was just $70M, leaving NI with a 1.7 debt-to-equity ratio and a 0.7 current ratio.

Get Full Access →NiSource Inc. (NI) is a regulated utility with an unusually visible growth program. Its traditional gas and electric networks provide the base, while Amazon and Alphabet contracts create an electric-load expansion opportunity tied to customer savings and Indiana economic development.
The numbers support a constructive medium-term view. Revenue rose from $4.90B in 2021 to $6.64B in 2025, operating margin expanded to 27.6%, management reaffirmed 2026 adjusted EPS guidance of $2.02 to $2.07, and the long-term adjusted EPS growth target remains 9% to 10%.
The numbers also define the risk. Debt reached $17.57B by June 30, 2026, cash was $70M, annual free cash flow was negative $420M in 2025 and Q2 adjusted EPS fell to $0.16 from $0.22. NI is therefore a Buy for investors who value visible regulated growth and can tolerate financing and regulatory risk, not a defensive substitute for a low-debt utility.
With a fair value estimate of $48.50 and a quoted price of $41.49, the risk-reward profile is favorable enough for a measured position. The thesis becomes stronger if rate recovery, Alphabet's load ramp and customer bill savings develop as management described; it weakens if debt growth outpaces regulated earnings and cash generation.
