SEC weighs Texas Stock Exchange's mandatory broker voting rule

SEC weighs Texas Stock Exchange's mandatory broker voting rule

Rule Changes

Proposal would require brokers to vote uninstructed shares in line with received instructions

October 2nd, 2026: SIFMA files comment on TXSE proxy rule

Overview

Updated Oct 17

The Securities and Exchange Commission opened formal proceedings in September to decide whether Texas Stock Exchange, a challenger to NYSE and Nasdaq, may require brokers to vote shares when clients give no instructions. Under the proposal, uninstructed shares would be allocated proportionally, matching how instructed investors voted on each item, and cast as abstentions when no instructions arrive on that matter.

The comment period closed October 2 and the rebuttal deadline passed October 16. SIFMA backed the rule's goal of improving quorum and retail representation but flagged operational problems and proposed conditions. The Council of Institutional Investors and two other commenters oppose it, saying it would distort election results and weaken investor protections.

Why it matters

If approved, this rule would let one exchange force brokers to vote uninstructed shares in ways no major US exchange currently allows, changing election outcomes.

Scenarios

1

SEC approves TXSE proportional proxy voting rule

Possible Resolves by Feb 28, 2027

Discussed by: SEC Division of Trading and Markets; the proposal's own design as a uniform allocation method

The commission could find the rule consistent with Section 6(b)(5), viewing it as a transparent, mechanical means to boost representation of broker-held shares. Approval would let TXSE implement proportional voting on all proposals, including non-routine matters where other exchanges restrict broker discretion.

2

SEC disapproves TXSE proxy voting rule

Possible Resolves by Feb 28, 2027

Discussed by: Commenters opposing the proposal; SEC proceedings notice flagging investor-protection concerns

The commission could conclude the rule distorts shareholder votes, circumvents majority-voting requirements, and conflicts with investor-protection standards under Section 6(b)(5). Disapproval would bar TXSE from implementing the rule and could lead the exchange to revise or abandon it.

3

TXSE withdraws and revises the proposal

Possible Resolves by Q1 2027

Discussed by: Standard practice where exchanges amend rules in response to SEC or commenter concerns

Facing opposition and a lengthy review, TXSE could withdraw SR-TXSE-2026-008 and file a revised version addressing concerns about vote distortion and majority requirements. A revised rule might narrow the scope, add exclusions, or change how uninstructed shares are allocated.

4

SEC approves TXSE rule with conditions

Possible Resolves by Dec 8, 2026

Discussed by: SIFMA comment letter; SEC proceedings notice

The SEC could approve the rule while imposing conditions like those SIFMA proposed: a 12-month implementation period, required technical guidance, and a phased rollout. That would let TXSE proceed but delay the rule's effective date.

Historical Context

3 moments from history that rhyme with this story — and how they unfolded.

2006–2010

NYSE Rule 452 broker-vote reform (2006–2010)

For decades, NYSE Rule 452 let brokers vote uninstructed shares on routine matters. After the 2008 financial crisis, the SEC narrowed that discretion, barring broker votes on executive pay and director elections.

Then

Brokers stopped voting uninstructed shares on the most contested corporate matters.

Now

The default became abstention on non-routine proposals across US exchanges, a norm TXSE's rule would now reverse.

Why this matters now

TXSE's proposal directly challenges the post-2010 consensus that brokers should not cast uninstructed votes on contested matters.

2010–2011

Business Roundtable v. SEC, proxy access vacated (2010–2011)

The SEC adopted Rule 14a-11 allowing shareholders to nominate directors. The D.C. Circuit vacated it, ruling the SEC failed to adequately assess the rule's costs and effects.

Then

The proxy access requirement was struck down.

Now

Courts signaled that proxy rules must be backed by rigorous economic analysis.

Why this matters now

The SEC's current review of TXSE's rule faces the same demand to weigh costs and distortions against any participation benefits.

2021–2022

Universal proxy rule (2021–2022)

The SEC required that proxy cards in contested elections list both the company's and the dissident's nominees, letting shareholders mix their choices.

Then

Proxy contests became easier to win for challengers.

Now

The rule shifted the mechanics of corporate elections and drew legal challenges from opponents.

Why this matters now

It shows how one SEC rule change can alter the balance of power in corporate elections, much as TXSE's proportional voting rule would.
