NiSource Inc. 2024 Annual Report (10-K) Summary

Business Context and Reporting Period

Company: NiSource Inc.
Reporting Period: Fiscal year ended December 31, 2024.
Business Overview: NiSource is an energy holding company with fully regulated natural gas and electric utility subsidiaries serving approximately 3.8 million customers across six states (Indiana, Ohio, Pennsylvania, Virginia, Kentucky, and Maryland). Operations are divided into two reportable segments: Columbia Operations (natural gas distribution) and NIPSCO Operations (natural gas and electric distribution/generation in northern Indiana).
Key Strategic Focus: The company is executing a major energy transition strategy, retiring coal-fired generation (targeting completion by 2028) and replacing it with renewable resources (wind, solar, battery storage) and natural gas peaking facilities. Significant capital is being deployed toward infrastructure modernization, safety programs, and data center load growth management.

Key Financial Metrics (Year Ended Dec 31, 2024)

Note: Operating income increased despite a slight revenue decline, driven by lower cost of energy (passed through to customers) and higher AFUDC (Allowance for Funds Used During Construction) related to renewable projects.

Material Changes vs. Prior Period

• Revenue Decline: Total operating revenues decreased by $50.3 million primarily due to lower commodity costs passed through to customers and warmer weather in the Columbia segment (17% warmer than normal heating degree days).
• Profitability Growth: Operating income rose 12.4% to $1.46 billion. This was driven by new base rates, regulatory capital programs, and increased AFUDC, partially offset by higher depreciation and interest expenses.
• Capital Spending Surge: Capital expenditures increased significantly to $3.69 billion (up from $2.69 billion in 2023), reflecting heavy investment in the generation transition (renewables and storage) and infrastructure modernization.
• Debt Structure: Total indebtedness increased to $13.96 billion. The company issued $2.23 billion in long-term debt in 2024 to fund capital projects and refinancing, while repaying $1.65 billion in short-term credit agreements.
• Noncontrolling Interest: Net income attributable to noncontrolling interest turned positive ($84.3 million) compared to a loss in 2023, following the NIPSCO Minority Interest Transaction with Blackstone.

Guidance, Outlook, and Risks

Outlook and Guidance:

• Capital Plan: NiSource expects to invest approximately $19.4 billion from 2025 to 2029 in infrastructure modernization, generation transition, and customer growth. This includes an estimated $1.6 billion in additional renewable generation projects.
• Rate Cases: Several rate cases are pending or in process, including NIPSCO Electric (settlement filed Feb 2025 for $257M revenue increase) and Columbia of Virginia (settlement filed Dec 2024 for $28.2M revenue increase).
• Dividends: The Board declared a quarterly dividend of $0.280 per share in January 2025. The company intends to continue regular quarterly cash dividends, subject to earnings and regulatory conditions.

• Energy Transition: The company is on track to retire R.M. Schahfer coal units by end of 2025 and Michigan City coal units by end of 2028. New renewable and storage projects (Cavalry, Dunns Bridge II) are in service or nearing completion.
• Data Centers: Management is evaluating data center development opportunities in northern Indiana, which could drive significant load growth requiring new generation and transmission capabilities.
• Transformation: The company achieved the first major milestone of its enterprise-wide transformation roadmap, implementing a Work and Asset Management (WAM) system to optimize field operations.

• Regulatory Risk: Outcomes of rate cases and regulatory approvals for cost recovery (e.g., for coal retirement and renewable investments) are uncertain and could impact earnings.
• Construction and Supply Chain: Delays or cost overruns in capital projects due to supply chain constraints, labor shortages, or permitting issues could adversely affect financial results.
• Climate and Environmental: Physical climate risks (extreme weather) and transition risks (new EPA rules on emissions, methane fees) pose operational and financial challenges.
• Cybersecurity: Increased sophistication of cyber-attacks on critical infrastructure remains a material risk.

Key Facts for Investor Verification

• Coal Retirement Timeline: Verify the specific dates and regulatory approvals for the retirement of R.M. Schahfer (end of 2025) and Michigan City (end of 2028) coal units, as delays could impact the generation transition strategy.
• Rate Case Settlements: Monitor the final approval and implementation dates for the NIPSCO Electric and Columbia of Virginia rate case settlements filed in late 2024/early 2025 to confirm revenue recovery.
• Capital Expenditure Execution: Track the actual spend against the $19.4 billion 2025-2029 forecast, specifically regarding the $1.6 billion in renewable generation investments and data center-related infrastructure.
• Debt Covenants: Confirm continued compliance with the 70% debt-to-capitalization ratio covenant (currently at 52.6%) and monitor credit rating outlooks (currently BBB+/Baa2 Stable).
• Noncontrolling Interest Impact: Assess the ongoing impact of the Blackstone minority interest transaction on net income attributable to common shareholders and cash flow distributions.
