NiSource (NI) Q1 2026 earnings review
GenCo Data Center Deals Supercharge Long-Term Growth
NiSource delivered a strong Q1 with adjusted EPS of $1.06 (+8% YoY), driven by base rate increases across its footprint. But the real story is the accelerating momentum of its GenCo data center strategy. Adding Alphabet (300 MW) to its existing Amazon deal prompted management to raise its 2026-2033 EPS CAGR target from 8-9% to an industry-leading 9-10%. While the base utility chugs along at a reliable 6-8% growth clip, GenCo is transforming NiSource into a premier infrastructure play. Execution and regulatory risks loom over the $7.6B data center capital plan, but the dual-engine growth narrative is highly compelling.
🐂 Bull Case
The GenCo structure cleverly insulates retail customers while capturing massive load from hyperscalers. The new Alphabet deal and Amazon expansion validate the Northern Indiana data center thesis, driving a $7.6B incremental CapEx opportunity.
Stripped of the data center hype, the base utility remains incredibly solid. A $21B base capital plan and constructive trackers underwrite a highly visible 6-8% base EPS growth rate.
🐻 Bear Case
The $7.6B GenCo plan requires flawless EPC execution and complex IURC approvals. Any delays in turbine deliveries, transmission upgrades, or regulatory pushback will immediately compress the aggressive 9-10% CAGR target.
A recent union lockout at NIPSCO and extreme weather damage to the Dunn's Bridge I solar facility highlight the very real physical and operational frictions inherent in running a legacy utility.
⚖️ Verdict: 🟢
Bullish. The core regulated business is humming, and the GenCo data center overlay provides a highly visible, contracted growth vector that few utility peers can match. The raised long-term EPS CAGR is a massive positive signal.
Key Themes
Alphabet Joins GenCo, Driving CAGR Upgrade
The GenCo narrative is accelerating. NiSource signed a new 15-year, 300 MW capacity agreement with Alphabet and expanded the existing Amazon deal by 400 MW. This critical mass of hyperscaler demand allowed management to raise the 2026-2033 consolidated adjusted EPS CAGR to 9-10% (up from 8-9%). The GenCo strategy alone is expected to add $7.6B in capital investment through 2030.
Base Rate Execution Remains the Bedrock
While GenCo gets the headlines, standard utility blocking-and-tackling is driving current earnings. NIPSCO saw an $83.7M YoY revenue uplift from base rate proceedings and regulatory capital programs, while Columbia Operations added $56.6M. This regulatory execution perfectly underpins the base plan's 6-8% annual EPS growth target.
Labor Lockout Incurs Incremental Costs
On April 2, 2026, NIPSCO locked out employees represented by the United Steelworkers after contract negotiations stalled. While agreements were ratified by May 1 to end the lockout, NiSource explicitly noted they incurred 'incremental costs to support our work continuity plans.' This highlights labor inflation and operational friction as a persistent risk.
The 'Flat O&M' Narrative vs. GAAP Reality
Management continues to pitch a 'Flat O&M' narrative driven by AI and operational excellence (Project Apollo). However, actual Q1 GAAP Operation & Maintenance expense jumped 14% YoY to $489.2M (from $427.8M). While ~$34.7M of this increase is tied to higher tracker deferrals (which are offset in revenue), the company still cited ~$9.5M in 'higher outside services expenses' as an unfavorable drag across both segments. True un-tracked costs are creeping up.
Physical Climate Risk Hits Dunn's Bridge I
In March 2026, NiSource experienced extreme weather damage to its Dunn's Bridge I solar generation facility. While management expects insurance to cover the bulk of the loss (less deductibles), this introduces near-term downtime and highlights the physical climate risks to the company's expanding renewable portfolio.
Coal Plant Mandate Complicates Generation Transition
The DOE and MISO are forcing NIPSCO to keep the R.M. Schahfer coal facility running under a 202(c) emergency order due to regional energy shortages, delaying its planned 2025 retirement. NIPSCO is fighting for cost recovery at FERC and the IURC. This macro grid reliability issue creates regulatory headaches and complicates NiSource's path to its 2040 Net Zero goal.
Other KPIs
Stable. Up 9.3% YoY from $437.6M in 25Q1. Growth was driven almost entirely by $56.6M in new rates from base rate proceedings and capital programs, which effectively absorbed higher depreciation ($12.7M) and outside services expenses ($4.9M).
Accelerating. Up 14.1% YoY from $303.3M in 25Q1. This segment is benefiting massively from the implementation of new electric and gas rates ($83.7M revenue uplift). Weather was actually a $7.9M drag on the gas side, showcasing the raw earnings power of the new tariff structures.
Decelerating. Down significantly from $686.4M in 25Q1. The $244.1M drop was primarily driven by working capital timing—specifically negative swings in exchange gas receivables, accounts payable, and prepayments. Liquidity remains robust at $1.63B.
Guidance
Stable. Management reaffirmed this range, which implies ~8% YoY growth at the midpoint. This consists of $2.01-$2.05 from the Base Plan and $0.01-$0.02 from GenCo.
Accelerating. Raised from the prior 8%-9% target. This represents a massive shift in the long-term earnings power of the company, driven explicitly by the new Alphabet and Amazon data center capacity commitments.
Stable. The 5-year outlook breaks down into $21.0 billion for the Base Plan and $7.6 billion for GenCo data center investments, fueling a consolidated rate base CAGR of 9%-11%.
Key Questions
Quantifying the Labor Lockout
You noted incremental costs to support work continuity plans during the USW lockout in April. Can you quantify this O&M drag for Q2, and what are the long-term wage inflation implications of the ratified agreements?
Alphabet IURC Approval Confidence
The Alphabet contract and the amendment to the Amazon contract both require IURC approval. Given the complexities of the 'Pool Resource' model versus dedicated assets, what is your confidence level in securing these approvals without material concessions?
Dunn's Bridge I Solar Damage
Regarding the extreme weather damage at Dunn's Bridge I, how long do you expect the facility to be offline, and how are you managing replacement power costs in the interim?
MISO Accreditation & GenCo CapEx
With MISO's resource accreditation rules evolving and the DOE forcing the Schahfer coal plant to remain online, how much contingency is built into your $7.6B GenCo CapEx plan if you are forced to pivot resource types to meet data center capacity requirements?
