Financial Performance Overview: Stability and Growth Metrics#
NiSource’s most recent financial data reflects a company balancing investment with operational efficiency. The FY 2024 revenue stood at $5.46 billion, a slight decrease of -0.91% year-over-year, while net income increased by +6.45% to $760.4 million, demonstrating improved profitability. The earnings per share (EPS) grew by +9.46% to $1.85, reinforcing earnings quality.
The company’s gross profit margin improved markedly to 51.47% in 2024 from 45.2% in 2023, signaling enhanced cost control or pricing power.

These margin improvements highlight NiSource’s ability to leverage its operational scale and manage expenses effectively amid capital-intensive growth.

Capital Expenditure and Cash Flow Dynamics#
NiSource’s capital expenditures remain robust, with $2.64 billion invested in property, plant, and equipment in 2024 focused on infrastructure modernization. However, this has led to a negative free cash flow of -$861.5 million in 2024, reflecting heavy reinvestment in growth initiatives.
Operating cash flow remains strong at $1.78 billion, sufficient to cover dividend payments of $489.2 million and partial debt servicing. The company’s net cash used in financing activities was -$651 million, indicating ongoing debt repayment or other financing actions.
Cash Flow Summary Table#

| Capital Expenditure | $2.64B | $2.65B | Sustained high investment |
| Dividends Paid | $489.2M | $457.3M | Dividend growth consistent |
