Comparison to Industry Standards

• The grant of restricted stock units to a director is a common compensation practice across publicly traded companies, including those in the financial services sector like Charles Schwab (SCHW) or E*TRADE (MS).
• The use of a Rule 10b5-1(c) plan for the transaction aligns with best practices for insiders to avoid accusations of trading on material non-public information.
• Stock splits, such as the four-for-one split by Interactive Brokers, are also a common corporate action, often aimed at making shares more accessible to a broader range of investors, similar to splits seen in companies like Apple (AAPL) or Tesla (TSLA) in the past.

Key Dates

Recommendation

This Form 4 details a routine, pre-planned annual stock grant to a director as part of their compensation, which is a standard corporate governance practice. While it shows continued alignment of director interests with shareholders, it does not present new material information that would fundamentally alter the investment thesis for Interactive Brokers Group. The stock split is also a non-dilutive event. Therefore, a 'hold' recommendation is appropriate as this filing does not provide a catalyst for a change in investment strategy.
