2.2% upside to avg target

Duke Energy locked in its fourth consecutive quarter of rate-base expansion above 7% in early 2026, anchoring its investment thesis on exactly the same macro argument NiSource is making: hyperscale data center demand in the U.S. is a structural, multi-decade power procurement event. Duke raised equity at a premium to book, extended its regulated asset base, and guided to 5-7% annual earnings per share growth through the end of the decade. Wall Street received it as confirmation that the AI infrastructure supercycle had permanently re-rated the utility sector’s growth ceiling.
The Southeastern corridor Duke serves gave it something NiSource doesn’t have in equal measure: regulatory environments that move faster on rate-case recovery. Duke’s jurisdictions, Florida and the Carolinas, have historically compressed the lag between capital deployment and authorized return. Duke spent aggressively; its regulators approved aggressively. The model worked because cost recovery was nearly contemporaneous with spend.
That compression is jurisdiction-specific. Midwestern regulators have not delivered it.
NiSource’s Indiana and Ohio Exposure — Where the Duke Comparison Breaks
NiSource enters paragraph three because the comparison earns it. Operating income grew from $1.3 billion in 2023 to $1.5 billion in 2024 to $1.8 billion in 2025, per Finnhub data. That trajectory — roughly $250 million of annual incremental operating income — comes from regulated rate-base additions, not accounting adjustments. The partnerships with Alphabet and AWS are not the cause of that income yet; they are the justification for continued capital deployment that will eventually produce it.
$2.7 billion in FY2025 capital expenditure against $1.8 billion in operating income. Sit with that ratio for a moment. Capital intensity at 1.5x operating income is not unusual for a regulated utility in a build cycle, but it means free cash flow is deeply negative, and every dollar of that deficit must be financed. The $22.8 billion market capitalization, per Yahoo Finance, is supported by a balance sheet that depends on debt markets remaining cooperative. They have been. The question is whether they stay that way.
The 2-year Treasury yield hit 3.7% in March 2026, per US Treasury data, reversing a decline that had held at 3.5% across October through February. That four-month plateau followed by a reversal is the market communicating something specific: the rate-cutting cycle that capital-intensive utilities priced into their forward models is not arriving on the schedule assumed. The Fed funds rate has sat at 3.6% since January, per the Federal Reserve. For a company financing a $2.7 billion annual capex program, the difference between 3.5% and 3.7% on short-duration instruments flows directly into weighted average cost of capital.
WACC is the variable the current valuation cannot afford to have move against it.
What the Alphabet and AWS Contracts Don’t Resolve
Long-term power agreements with hyperscale tenants produce revenue certainty, not margin certainty. The distinction carries more weight for NiSource than for a software company because utility operating margins are not determined by the contract price. They are determined by whether the regulator approves cost recovery on the infrastructure built to serve that contract. Grid resiliency upgrades, interconnection costs, and transmission buildout required to physically deliver power to data center clusters sit in a regulatory queue. If approval timelines slip, capital is deployed but returns are deferred. That deferral compounds the free cash flow problem.
The operating income trend — $1.3B, $1.5B, $1.8B — shows the existing regulated asset base performing well. Operating leverage on incremental rate-base additions is visible. But the $2.7 billion being spent now will take 18 to 36 months to flow into authorized returns under typical rate-case cycles in Indiana and Ohio.
Over the next 12 months, NiSource’s ability to sustain operating income expansion depends more on regulatory cost-recovery timing and debt financing rates than on the Alphabet and AWS contracts themselves; if the 2-year Treasury yield remains above 3.6% while rate-case cycles extend, the current price has absorbed more upside than the near-term fundamentals support.
The thesis requires four conditions to hold simultaneously: rate-case approvals in Indiana and Ohio move faster than their historical average; construction cost inflation on grid buildout stays contained; the 2-year yield retraces toward 3.5% and holds; and hyperscale customers don’t renegotiate timelines as their own capex cycles compress. Each condition individually has reasonable odds. All four together is a different probability.
The counter-scenario is straightforward. If the Fed delivers two cuts before year-end, short-duration yields compress, NiSource’s refinancing costs drop, and the WACC argument inverts. The operating income trajectory reasserts itself as the primary valuation driver. In that environment, the $54.0 analyst high target becomes the relevant reference, not the $48.8 consensus average. That scenario is plausible. It requires a macro outcome, not just a company execution outcome, which means the upside is not in NiSource’s control.
The stock at $47.7 sits $1.1 below the consensus average, per Yahoo Finance. The consensus average is not a ceiling, but it is the market’s current answer to the question of what this operating income trajectory is worth at current rates. What the consensus appears to underweight is the duration mismatch: NiSource is spending at 2026 rates to earn returns that regulators will authorize in 2027 and 2028. That gap has a cost. The 2-year yield chart captured it in March.
NiSource’s operating income trajectory: $1.3B → $1.5B → $1.8B. FY2025 capex: $2.7B. Current price: $47.7. Consensus average: $48.8. 2-year yield: 3.7%. Fed funds: 3.6%. The numbers sit next to each other without requiring a verdict.
