COMPETITIVE MOAT
↑Regulated Monopoly Infrastructure
NiSource operates essential gas and electric infrastructure, granting it a de facto monopoly in its service territories. This physical network is extremely difficult and costly for competitors to replicate.
↑High Switching Costs for Customers
Residential and commercial customers have virtually no ability to switch energy providers due to the nature of the regulated utility model. This creates a stable and predictable customer base.
↑Long-Term Capital Intensive Assets
The company's extensive network of pipelines and distribution systems represents a significant barrier to entry. These assets require massive upfront investment and long lead times to build.
INVESTMENT RISKS
↓Interest Rate Sensitivity
As a capital-intensive utility, NiSource relies heavily on debt financing. Rising interest rates increase borrowing costs, potentially impacting profitability and dividend capacity.
↓Environmental and Climate Change Regulations
Increasingly stringent environmental regulations and the transition to cleaner energy sources pose significant compliance costs and potential asset stranding risks.
↓Operational and Safety Incidents
Accidents or service disruptions can lead to significant financial penalties, reputational damage, and increased regulatory oversight, impacting operations and investor confidence.

The trailing twelve-month PE ratio of NI reflects how much investors pay per dollar of NiSource Inc's earnings. This metric is most useful when compared to Regulated Gas peers and the company's own historical range.
NI's PE of 21.4x combined with a PEG ratio of -1926118451158560.75 provides a growth-adjusted perspective. NI has negative earnings, so its PE and PEG ratios are not meaningful here and cannot tell you whether the stock is over or undervalued. Keep in mind that PE-based valuation works best for profitable, mature companies — for high-growth or cyclical Regulated Gas, a DCF analysis may be more appropriate.
To value NiSource Inc using PE: (1) Compare the current PE (21.4x) against the Regulated Gas median to assess relative pricing, (2) check the PEG ratio (-1926118451158560.75) to adjust for growth expectations, (3) review the 5-year PE range to identify where the stock sits historically, and (4) estimate fair value by multiplying a target PE by forward EPS estimates. This relative approach complements DCF's absolute valuation.
NI's PEG ratio is -1926118451158560.75, calculated by dividing the PE ratio (21.4x) by the expected earnings growth rate. Because NI has negative earnings, its PEG ratio is not meaningful and should not be read as a sign of under or overvaluation. Note that PEG accuracy depends on the reliability of growth estimates.
PE ratio gives a quick relative read — how NI is priced versus Regulated Gas peers. DCF provides an absolute value based on projected free cash flows. For the most reliable valuation, use PE as a quick comparability screen and DCF for a deeper fundamental analysis. Each method has blind spots: PE ignores capital structure and cash flow quality, while DCF is sensitive to growth and discount rate assumptions.
P/E and DCF value NI with different methods and assumptions, so the two conclusions can differ. Compare the DCF intrinsic value.
