📈 Income Statement Summary
(Unit: $m, EPS in $)
| Income Statement Summary | FY2023 | FY2024 | FY2025 |
|---|---|---|---|
| Revenue | 4,340 | 5,185 | 6,205 |
| Operating Expenses | 1,271 | 1,490 | 1,434 |
| Operating Income | 3,069 | 3,695 | 4,771 |

| Net Income | 2,812 | 3,407 | 4,357 |
| EPS (Diluted) | 5.7 | 6.9 | 2.2 |
Plain English: Interactive Brokers continued to deliver strong earnings growth in FY2025. Revenue increased from $5.2bn to $6.2bn, mainly driven by higher interest income and continued trading activity. Operating expenses actually declined slightly in FY2025 despite revenue growth, which helped operating income rise sharply. This shows that IBKR’s highly automated business model continues to scale efficiently.
The unusually lower FY2025 EPS compared to FY2024 primarily reflects the company’s 4-for-1 stock split and related share presentation adjustments, not a collapse in profitability. Net income still increased strongly year over year.
