a)Disclosure controls and procedures. The Company’s management, with the participation of its Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the Company’s disclosure controls and procedures (as defined in Rule 13a-15(e) and Rule 15d-15(e) under the Securities Exchange Act of 1934) as of the end of the period covered by this report.

CT Plan Order (Continuation of Consolidated Data Plans Proceeding)

​

On May 6, 2020, the SEC issued an order (the “Consolidated Data Plan Order”) that directed the U.S. equities exchanges and FINRA to submit a new National Market System (“NMS”) Plan regarding Consolidated Equity Market Data. The contemplated new NMS Plan is referred to as the “CT Plan” and it will replace three Equity Data Plans that govern the dissemination of real-time, consolidated market data for NMS stocks. The Consolidated Data Plan Order set forth certain changes to be included in the proposed CT Plan, including governance structure changes related to voting rights and a deadline of August 11, 2020 by which the proposed CT Plan had to be filed.

On June 29, 2020, the Company filed a Petition for Review (“PFR”) with the Court of Appeals for the D.C. Circuit Court (“D.C. Circuit) challenging the Consolidated Data Plan Order. Briefing concluded on March 12, 2021 and oral argument was held on April 26, 2021. On June 15, 2021, the D.C. Circuit issued an order dismissing the PFR for lack of jurisdiction, holding that the Consolidated Data Plan Order was not a “final order” because the SEC had not determined whether the challenged features would make it into the new CT Plan.

On August 6, 2021, the SEC issued an order approving the CT Plan that was previously filed on August 11, 2020 (as mandated by the Consolidated Data Plan Order) and subject to public comment (“CT Plan Order”). On August 9, 2021, the Company filed another PFR with the D.C. Circuit challenging the CT Plan Order and the prior Consolidated Data Plan Order. On September 13, 2021, the Company filed a motion requesting that the D.C. Circuit stay the CT Plan Order pending resolution of the appeal and also requesting that the D.C. Circuit expedite the appeal. On October 13, 2021, the D.C. Circuit granted the motion to stay the CT Plan order and to expedite the appeal. A briefing schedule has been established and briefing will occur in the fourth quarter of 2021 and conclude in the first quarter of 2022.

The new CT Plan approved by the SEC may cause the Company’s equities exchanges, BZX, BYX, EDGX, and EDGA, to require additional resources to comply with or challenge such new consolidated data plan and it may have a material impact on our business, financial condition and operating results if, for example, there is a negative impact on the applicable market data revenues that we receive that are generated from such new plan.

Market Data Infrastructure Final Rule

​

On December 9, 2020, the SEC issued a Market Data Infrastructure Final Rule (“Final Rule”), which makes significant additions to the content available on the Securities Information Processors (“SIPs”) and replaces the exclusive processors with a competing consolidator model. The Final Rule is limited to market data disseminated by the equities SIPs and does not apply to proprietary market data, or the dissemination of options market data through OPRA.

On February 5, 2021, the Company filed a Petition for Review (the “2/5 PFR”) with the Court of Appeals for the D.C. Circuit challenging the Final Order. Additionally, on February 5, 2021, the Company filed a motion for stay of the Final Rule with the SEC, which the SEC denied on March 24, 2021.

On March 24, 2021, the SEC filed a Motion to Dismiss (“MTD”) with the D.C. Circuit: (1) arguing that the PFR is not ripe because the Final Rule had not been published in the Federal Register (“FR”), (2) suggesting (if there is ambiguity) that the D.C. Circuit clarify whether publication in the FR opens the filing window, and (3) suggesting that the D.C. Circuit could hold the case in abeyance pending filing of a PFR after publication in the FR.

On April 9, 2021, the Final Rule was published in the FR. On April 13, 2021, the Company filed another PFR (the “4/13 PFR””) as a protective measure in the event the D.C. Circuit determined that the time to file a PFR does not commence until publication of the Final Rule in the FR.

On June 15, 2021, the D.C. Circuit entered an order granting the SEC’s MTD respecting the 2/5 PFR. This order does not affect the 4/13 PFR, which was filed after publication of the Final Rule in the FR on April 9, 2021. On July 9, 2021, the D.C. Circuit entered a briefing schedule and briefing is scheduled to conclude on January 20, 2022.

The implementation of the Final Rule could cause Cboe’s equities exchanges, BZX, BYX, EDGX, and EDGA, to require additional resources to comply with or to challenge the new rules and they may have a material impact on our business, financial condition and operating results if, for example, there are lower SIP plan revenues or we must reduce the fees we charge for market data. The Company intends to litigate the matter vigorously.
