Alliant Energy (LNT) Financials

Alliant Energy’s recent financials show a utility with steady revenue growth, solid operating cash flow, and ongoing capital spending, but also one that continues to rely on debt to fund expansion. Over the last four years, the company has generally grown earnings and revenue, while balance sheet leverage and interest costs have remained important watch items for investors.

• Revenue has trended upward overall. Quarterly revenue rose from about $1.03 billion in Q1 2024 to $1.18 billion in Q1 2026, with most recent quarters generally running above prior-year levels.
• Net income improved meaningfully in 2025 and Q1 2026 versus 2024. Q1 2026 net income was $224 million, up from $213 million in Q1 2025 and well above Q1 2024’s $158 million.
• Operating income has also strengthened. Q1 2026 operating income reached $249 million versus $257 million in Q1 2025 and $222 million in Q1 2024, showing the business can still generate healthy earnings before interest.
• Operating cash flow remains strong. Q1 2026 operating cash flow was $368 million, compared with $249 million in Q1 2025 and $307 million in Q1 2024.
• Depreciation and capital spending reflect a large regulated-utility asset base. PP&E climbed to about $20.6 billion in Q1 2026 from $19.0 billion in Q1 2025 and $17.4 billion in Q1 2024, signaling continued investment in infrastructure.
• Gross margins have been fairly consistent. The company has kept revenue growth ahead of cost growth in several periods, but operating costs still consume a large portion of sales.
• Share count has been relatively stable. Diluted shares were about 258.8 million in Q1 2026 versus 257.2 million in Q1 2025, so earnings growth has not relied heavily on major dilution.
• Dividend payments appear manageable for now. Alliant Energy continued paying dividends while still producing positive operating cash flow, which is typical for a utility.
• Debt levels remain high and are an ongoing drag on earnings. Long-term debt was $11.1 billion in Q1 2026, and interest expense was $142 million, leaving less room for equity holders.
• Free cash flow is under pressure because capital spending is heavy. In Q1 2026, capital expenditures of $414 million exceeded operating cash flow, meaning the company still needs outside financing to support investment.

Balance sheet trends are mixed but generally stable for a utility. Total assets increased to $24.8 billion in Q1 2026 from $22.7 billion in Q4 2024, while equity also rose to $7.4 billion from $7.0 billion. That said, liabilities remained substantial at $17.3 billion, and the current ratio remains below 1.0, which is common for utilities but still worth monitoring.

One of the clearest trends is higher financing activity. In multiple quarters, Alliant Energy issued debt to fund capital needs and manage repayments. That is not unusual in this industry, but it does mean investors should expect leverage and interest expense to stay central to the investment case.

Bottom line: Alliant Energy looks like a classic regulated utility story: stable and growing revenue, dependable earnings, and strong operating cash flow, offset by heavy capital spending and significant debt. For income-focused investors, the business appears durable, but the stock’s longer-term performance will likely depend on how well management controls financing costs while continuing to expand the asset base.
