Interactive Brokers Group, Inc. 8-K

What Happened

• Interactive Brokers Group, Inc. announced and furnished a press release on January 20, 2026 reporting its financial results for the quarter ended December 31, 2025. The company filed an 8‑K (Item 2.02) to disclose these quarterly results; the press release is included as Exhibit 99.1 to the filing.
• The report was signed by Paul J. Brody, Chief Financial Officer, Treasurer and Secretary, on January 20, 2026.

Key Details

• Filing date: January 20, 2026 (8‑K filed with the SEC).
• Reporting period: Quarter ended December 31, 2025 (Q4 2025 results reported).
• Exhibit: Press release dated January 20, 2026 furnished as Exhibit 99.1.
• Disclosure status: Information is furnished (not “filed”) for purposes of Section 18 of the Exchange Act and is not automatically incorporated by reference into other SEC filings.

Why It Matters

• Quarterly results are a primary source of up‑to‑date performance data (revenues, net income, client metrics, etc.); investors should read the furnished press release for the full financial and operational details.
• The 8‑K formally alerts the market that Interactive Brokers has released its Q4 2025 results; because the release is furnished rather than filed, it is not treated the same way for certain legal incorporation purposes in other SEC filings.
