Honestly, its history isn't a single founding moment but a century of strategic consolidation and transformation. It all starts with a local utility in Northern Indiana, and it has evolved into a multi-state operator with a massive, forward-looking capital plan.

The company you know as NiSource Inc. is the result of decades of mergers and reorganizations, especially as federal regulations reshaped the utility landscape. Today, it serves approximately 3.3 million natural gas customers and 500,000 electric customers across six states.

Given Company's Founding Timeline

Year established

The company's deepest roots trace back to 1912 with the formation of the Northern Indiana Public Service Company (NIPSCO). The modern corporate entity, however, was organized in 1987 as NIPSCO Industries, Inc., before officially becoming NiSource Inc. in April 1999.

Original location

The core operations were initially focused in Northern Indiana, consolidating various smaller utility providers to create a more efficient service for the region.

Founding team members

Specific individual founders are not widely publicized. The company was born from the consolidation of several utility companies, reflecting a strategic, rather than a single-person, founding. Key predecessor companies include the Springfield Gas Light Company, founded in 1847.

Initial capital/funding

Details on the initial capital for the predecessor companies are not readily available in public disclosures. The early growth was fueled by the consolidation of existing regional utilities and subsequent public financing to support infrastructure expansion.

NiSource Inc.'s Strategic Advantages

NiSource's success is built on the predictable nature of its regulated utility structure, plus its ability to execute on large-scale, long-term capital projects. This is defintely a low-risk, high-visibility growth model.

• Regulated Monopoly Status: The company holds exclusive rights to provide gas and electric service in its operating territories across six states, ensuring a stable customer base and predictable cash flows.
• High-Growth Capital Plan: The substantial $19.4 billion five-year capital plan is expected to drive an annual rate base growth of 8%-10% through 2029, which is top-tier for a utility.
• Data Center Load Capture: A new, significant growth vector is the $7.0 billion in regulated capital investment for data center infrastructure, which is immediately accretive and secured with a key investment-grade customer, leveraging the Northern Indiana service territory's unique position.
• Favorable Regulatory Foundation: NiSource has a proven track record of constructive regulatory outcomes, including final rate orders in key states like Virginia and Indiana in 2025, which reduces regulatory lag (the time between investment and rate recovery).

What this estimate hides is that the success of the new data center strategy depends on continued regulatory support and the timely execution of the large-scale infrastructure build-out. Still, the core business remains resilient.

NiSource Inc. (NI) How It Makes Money

NiSource Inc. generates its revenue primarily by delivering essential natural gas and electricity to residential, commercial, and industrial customers across six states, operating as a fully regulated utility. The core of its financial model is a predictable, rate-based return on its massive infrastructure investments, which are approved by state public utility commissions.

NiSource Inc.'s Revenue Breakdown

The company's revenue engine is split nearly 50/50 between its two main operating segments, Columbia Operations (natural gas) and NIPSCO Operations (electric and gas), reflecting a crucial diversification across fuel type and geography. Here's the quick math on the trailing twelve months (TTM) revenue through September 30, 2025, which totaled approximately $6.33 billion.

Business Economics

You need to understand that utility economics are not like a tech startup; they are a regulated monopoly, which means stability, but also a cap on returns. NiSource's earnings stability comes from its rate base, which is the value of its utility assets (like pipelines and power plants) on which regulators allow it to earn a return. The company is projecting an annual rate base growth of 8% to 10%, which is a defintely strong signal for future earnings.

The pricing strategy is straightforward: state utility commissions approve the rates charged to customers, ensuring the company can recover its operating costs and earn an authorized return on equity (ROE) on its capital investments. This regulatory foundation shields the business from much of the volatility seen in non-regulated energy markets, so earnings are highly predictable.

• Rate Case Recovery: Recent regulatory wins, like the Virginia rate case, authorized a $40.7 million revenue increase and a 9.75% ROE, directly supporting infrastructure investments.
• GenCo Model: The newly approved NIPSCO Generation LLC (GenCo) structure is a game-changer. It creates a separate, less-regulated entity to own and build generation assets specifically for high-demand customers like new data centers in Indiana.
• Customer Protection: The GenCo model is designed to shield existing NIPSCO retail customers from the costs of serving these new, massive-load data center developments, which is a smart way to manage political and customer risk while still capturing growth.

NiSource Inc.'s Financial Performance

The company is executing well on its financial commitments as of late 2025, with a clear focus on infrastructure modernization and the energy transition. The total revenue for the trailing twelve months ending September 30, 2025, was approximately $6.33 billion, marking a significant year-over-year increase of 19.62%.

For the full 2025 fiscal year, NiSource has narrowed its non-GAAP adjusted Earnings Per Share (EPS) guidance to the upper half of the $1.85 to $1.89 range, reflecting confidence in their operational delivery and regulatory success. This strong EPS growth is underpinned by a massive, multi-year capital plan.

• Capital Commitment: The company plans to invest $19.4 billion in its regulated utility infrastructure between 2025 and 2029, which is the primary driver of its expected 6% to 8% annual adjusted EPS growth.
• Year-to-Date Profit: GAAP net income available to common shareholders for the nine months ended September 30, 2025, was $671.7 million.
• Long-Term Growth: The consolidated capital expenditure plan has been extended, now totaling $28.0 billion through 2033, fueled by approximately $7.0 billion in strategic data center investments, which should drive an 8% to 9% adjusted EPS compound annual growth rate for the consolidated business through 2033.
