IEX Listings Timeline Update

IEX Trading Alert #2017 - 046

Overview

Last week, the SEC amended its Rule 146 to designate securities listed on IEX as covered securities for purposes of Section 18 of the Securities Act. With this amendment, IEX has cleared the final regulatory hurdle to launching as a primary listing exchange. With regard to timing, IEX plans to list its first company in early 2018. This timeline accommodates the 30-day operative delay of the amendment, which begins today, and year-end code-freezes across the industry during the holiday season.

IEX will continue to conduct the industry test of listings functionality on Saturday, November 4, 2017, as previously announced in IEX Trading Alert #2017 - 040, and will conduct an additional test on Saturday, January 6, 2018. IEX will provide more precise timing of the first listing at a later date.
