SENT ON BEHALF OF DataCT:

ACTION REQUIRED: New Agreements Required for Tape A, B and C Market Data

Submission Deadline: March 1, 2027

Effective April 1, 2027, the new CT Plan is expected to replace the legacy CTA and UTP Plans under a new, unified governance structure with a single AdministratorDataCT. This is a change to the Plan, its Policies, its Agreements and its Fee Schedule — not to the data feeds. Consolidatedtape.com will serve as the information source for the transition.

If your organization currently receives or distributes US Consolidated Tape™ data (consolidated market data for all US National Market System securities across Tapes A, B and C) action is required.

3. Review Agreements : Review the new CT Plan Agreements at Consolidatedtape.com/agreements and start your legal review now — every organization must be licensed under the new agreements before March 1, 2027.

WHAT'S CHANGING?

Today, Tape A and Tape B are administered under the CTA/CQ Plans by NYSE, while Tape C is administered under the UTP Plan by Nasdaq.

Effective April 1, 2027:

• The existing CTA/CQ and UTP Plans are expected to be replaced by a single Consolidated Tape Plan(CT Plan).
• DataCT will become the administrator of the CT Plan, replacing NYSE and Nasdaq in their current Administrator roles.

WHAT'S NOT CHANGING?

As part of this transition, there are:
