ICE's 20% threshold has four different effects

Intercontinental Exchange's new charter does not create one generic 20% cap. For a member of an ICE-controlled security-based swap execution facility, or SBSEF, voting power above 20% of any class is disregarded, while ownership of 20% or more is prohibited. Excess votes also leave the quorum calculation, and excess ownership enters a separate sale-and-repurchase procedure at par value, subject to legally available funds.

That distinction is the practical answer. A record showing 20% is incomplete until it says who the holder is, which related persons are aggregated, whether the measurement is voting or ownership, whether the boundary is exceeds or 20% or more, and which corporate action follows. The Eighth Amended and Restated Certificate became effective at 4:00 PM Eastern Time on August 28, 2026.

The question this map answers

How do ICE's SBSEF-specific 20% voting and ownership limits interact with related-person aggregation, quorum, and the charter's repurchase procedure, and which approval sequence made those provisions effective?

MyMap observed ICE's August 28 Form 8-K, filed charter, and March 30 proxy statement at 4:20 AM Pacific Time on August 30, 2026. In this article, SBSEF Member uses the charter's definition: a person that is a member of a security-based swap execution facility under Rule 242.802 of Regulation SE. Related Persons is a broad charter-defined aggregation that includes specified affiliates, coordinated holders, certain officers or managers, associated persons, and listed family or entity relationships. It is not shorthand for every business contact.

The map isolates the new SBSEF lanes. ICE's charter also contains separate rules tied to its control of national securities exchanges, including a general 10% voting limit and a general ownership concentration limit above 20%. Those provisions remain important, but combining them with the SBSEF tests would hide the exact boundary changed in 2026.

One number, two threshold operators

The charter uses different operators for voting and ownership:

The edge case matters. Exactly 20% is not above the SBSEF voting limit, but exactly 20% reaches the ownership prohibition. The charter measures both across the SBSEF Member and its Related Persons, so a holder-by-holder cap table is not enough when the definition requires aggregation.

The voting rule reaches direct or indirect voting, causing votes, and giving consent or proxy over the voting of an interest. It applies to each class of securities or other ownership interest. The ownership rule likewise reaches direct or indirect ownership of any class of voting securities or other voting interest. Neither rule should be rewritten as a statement that every ICE stockholder is capped at exactly 20%; the SBSEF-specific provisions start with the member-status test.

Voting, ownership, and quorum are three different records

When a covered voting interest exceeds 20%, the charter says ICE disregards votes purportedly cast above the limit. That changes counted voting power; it does not by itself say the underlying shares disappeared or were transferred.

Article IX then supplies a second consequence. Shares above the Voting Limitation, Recalculated Voting Limitation, or SBSEF Voting Limitation are not counted as present and are not counted as outstanding for determining quorum. The charter mentions waivers for the general voting and recalculated limits, but the quoted quorum exception does not identify a comparable waiver for the SBSEF Voting Limitation. MyMap therefore does not draw one.

Ownership is a different state. Article V says an SBSEF Member and Related Persons may not own 20% or more of any class. If their beneficial ownership is in excess of the SBSEF Concentration Limitation, they must sell promptly and ICE must purchase promptly, at par value and to the extent funds are legally available, enough voting interest to bring the group below 20%. The repurchased interest becomes treasury stock and ceases to be outstanding.

The filed language creates an awkward but important reading boundary: the prohibition begins at 20% or more, while the next sentence describes the repurchase duty when ownership is “in excess of” the limitation. This article does not invent a transaction result for an exactly-20% holding. It records the prohibition and flags the precise remediation step for counsel and the company to resolve from the full charter and facts.

A market trade can settle without erasing the limit

The charter says the ownership provisions do not preclude settlement of transactions entered through the New York Stock Exchange. But settlement is not a safe harbor from the concentration consequences. If a transfer produces ownership over the applicable limit, the holder and ICE remain subject to the stated sale and repurchase obligations.

That is why a compliance map needs at least five fields: holder identity, SBSEF member status, Related Persons, class-by-class voting power, and class-by-class ownership. Add the record date for a vote and the transfer or settlement time for ownership. A single percentage copied from a beneficial-ownership filing cannot answer every branch.

The board may require ownership and relationship information from a person it reasonably believes is subject to a voting or concentration limit. It may also seek information from a person at or above 5% whose ownership has not been reported to ICE. Good-faith board constructions under Article V, based on the information reasonably available, are conclusive and binding on ICE and its directors, officers, and stockholders under the charter's terms.

The amendment needed more than a board vote

ICE's proxy describes a staged approval path. The board approved and declared the amendments advisable in late February 2026. Stockholders approved Proposal 3 on May 15. Because ICE controls registered national securities exchanges, those exchanges had to file the proposed charter amendments with the SEC. The August 28 Form 8-K says each exchange met that requirement, allowing ICE to take the final action.

ICE then filed the restated certificate with Delaware on August 28. Exhibit 3.1 gives the exact effective time: 4:00 PM Eastern, or 1:00 PM Pacific. Filing the proxy in March did not make the provisions effective; neither did the May stockholder vote by itself.

Article X preserves a continuing review relationship. While ICE controls an exchange, a future charter amendment or repeal must go to each exchange board. If any such board determines SEC filing or approval is required under Section 19 of the Exchange Act, the change cannot take effect before that step is complete.

Confirmed, derived, and still unknown

The controlling sources confirm the SBSEF Member and Related Persons definitions; the exceeds 20% voting boundary; the 20% or more ownership prohibition; vote-disregard, quorum, information, and repurchase provisions; the board, stockholder, exchange-filing, and Delaware sequence; and the August 28 effective time.

MyMap derives the four-effect threshold map and the compliance join between member status, related-person aggregation, class, percentage, record date, and remedy. The >20% vote / ≥20% own shorthand is a faithful comparison of two clauses, not a substitute for the full charter.

The sources leave unknown whether any current holder crosses either SBSEF-specific threshold; which persons ICE would aggregate in a particular case; how ICE would address an exactly-20% ownership position under the prohibition and remedial wording; whether the board has requested information; and whether any repurchase notice, sale, or treasury-share conversion has occurred.

Reproducible mapping method and next step

Start with one row per holder and class. Record direct and indirect ownership, voting power, record date, SBSEF member status, every relationship used for aggregation, and the source supporting each field. Compute two outputs separately: voting power > 20% and ownership >= 20%. Never copy the result from one test into the other.

For a voting trigger, preserve gross voting power, disregarded votes, and resulting quorum inputs. For an ownership trigger, open a separate state record for notice, sale obligation, legally available funds, repurchase date, par-value price, and treasury-share conversion. Do not mark ownership remediated from a vote tally.

The immediate next step is to audit any ICE position connected to an ICE-controlled SBSEF at the related-person group and class level before the next record date or acquisition. This map is a source-reading and data-modeling aid, not legal advice or a finding about any stockholder.
