I. Self-Regulatory Organization's Statement of the Terms of Substance of the Proposed Rule Change

The Exchange proposes to modify its Fee Schedule, pursuant to IEX Rules 15.110(a) and (c), to change the existing definitions of “Real-Time” and “Delayed” in relation to its proprietary market data feeds, so that the interval that differentiates Delayed IEX Data from Real-Time IEX Data is fifteen (15) minutes instead of fifteen (15) milliseconds. IEX intends to implement the proposed changes beginning on February 1, 2025 to provide an opportunity for Data Subscribers ^[5] to update their IEX market data subscriptions to suit their particular market data needs.
