Corporate Shareholder Meeting, Proxy, and Written-Consent Requirements in Missouri

At a glance

Requirements one by one

Under § 351.020, Chapter 351 supplies the ordinary Missouri for-profit corporation rules used below.

Annual and special meetings use different sources of authority

Under § 351.225, the annual meeting is a director-election meeting on the day fixed in the bylaws. If the bylaws are silent, the fallback is the second Monday in January. Missing the designated time does not cause forfeiture or dissolution, but the section does not supply a shareholder court-order route.

The same section permits special meetings called by the board or a person authorized in the articles or bylaws. It gives shareholders no default percentage-demand route. Under § 351.235, the president, secretary, other officer, or caller to convene the meeting through the statutory notice.

Remote participation is board-authorized and safeguard-dependent

Under § 351.225(1), the board may authorize shareholders and proxyholders to participate remotely at a physical or remote-only meeting. The corporation must use reasonable measures to verify shareholder or proxyholder status, give a reasonable opportunity to participate and vote, allow the proceeding to be read or heard substantially concurrently, and maintain a record of remote votes and other action. A qualifying participant is deemed present in person.

Notice, waiver, adjournment, and postponement

Under § 351.230, written or printed notice is required 10 to 70 days before the meeting. Retainable electronic transmission counts as written notice. The notice states place, day, and hour, and a special notice states purpose. Mailed notice is delivered on prepaid deposit to the record address. Attendance waives a defect unless the holder attends expressly to object that the meeting was not lawfully called or convened. A signed written waiver works before or after the stated time under § 351.655.

Missouri expressly distinguishes changes after and before convening. Under § 351.268, an announced adjournment may move successively to a specified date up to 90 days later without new notice; moving more than 90 days or fixing a new record date requires notice. Before convening, the board may successively postpone up to 90 days unless the bylaws say otherwise, but must notify entitled record holders of the new date and place. The section permits defined public notice, including an SEC-filed public document, but that public-company method does not erase other applicable federal rules.

Record date and voting list

Under § 351.250, the board may close the transfer books or fix a record date no more than 70 days before the meeting. Without either action, the default is close of business on the 20th day before the meeting. That date carries to an adjournment or postponement. If every record holder at convening signs and delivers a pre-meeting waiver, the holders of record when the meeting convenes instead determine the vote.

Under § 351.255, the transfer-book officer prepares an alphabetical list with addresses and shares at least 10 days before the meeting, keeps it at the registered office during that period, and produces it throughout the meeting. A defect does not invalidate action, but the officer may owe resulting damages. The section does not add an electronic-network alternative for a remote-only meeting, so the statutory registered-office and meeting-access text still needs to be reconciled with the selected meeting method.

Proxies

Under § 351.245, a shareholder or attorney-in-fact may sign a writing, including by facsimile signature, or authorize a telegram, cablegram, facsimile, electronic, or telephone transmission. A transmission must supply information showing shareholder authority, and the vote inspectors or other validators must identify what they relied on.

A proxy expires after 11 months unless it states otherwise. Irrevocability requires express irrevocable language and a legally sufficient coupled interest, and lasts only while that interest continues. The surveyed section does not separately state when an ordinary proxy becomes effective, how an ordinary revocable proxy is withdrawn, or how death or incapacity affects it.

Quorum, voting, adjournment, and director elections

Under § 351.265, a majority of outstanding shares entitled to vote is the default quorum and an absolute statutory floor; the governing documents cannot reduce it. Abstention and withhold proxies count for quorum, and holders below quorum may adjourn under § 351.268.

With quorum, ordinary action requires a majority of shares entitled on the matter and represented, not merely a plurality of votes actually cast. An abstention proxy ordinarily remains represented on the matter, while a proxy without instructions on that matter ordinarily does not. Chapter 351, the articles, or a shareholder-adopted bylaw may require a greater vote (§ 351.270).

Director elections follow the majority-of-represented-shares rule unless cumulative voting applies. Section 351.265(2) makes plurality sufficient for a cumulative-voting election. Under § 351.245(3), cumulative voting is the default unless the articles or bylaws provide otherwise: votes equal shares' votes multiplied by directors to elect and may be concentrated or distributed.

Written consent

Under § 351.273, consents in writing must be signed by every shareholder entitled to vote on the matter. The consent must state the action, has the force of a unanimous meeting vote, and is filed by the secretary with shareholder minutes. Under § 351.215, the corporation separately keeps correct and complete shareholder minutes and grants holders access to corporate books at proper times under bylaw-prescribed regulations. Section 351.273 does not provide a nonunanimous route or separately state an electronic-consent method, signature date, delivery address, collection period, revocation, future or delayed effect, or notice to holders after action.

What trips people up

The January fallback is real. If the bylaws do not fix the annual meeting day, § 351.225 selects the second Monday in January; generic bylaws that omit a date do not leave timing wholly open.

There is no default shareholder demand percentage. Ownership alone does not call a Missouri special meeting. The board or a person authorized in the articles or bylaws must call it.

Quorum cannot be lowered below a majority. Section 351.265 starts with a governing-document variation clause but immediately makes majority of outstanding shares entitled to vote the minimum.

Cumulative voting is opt-out, not opt-in. Missouri's ordinary rule permits it unless the articles or bylaws provide otherwise.

Common questions

How much notice is required? Ten to 70 days, with place, day, and hour; a special meeting notice also states purpose (§ 351.230).

May a Missouri shareholder attend remotely? Yes, when the board authorizes the method and the corporation meets the identity, access, voting, and record safeguards in § 351.225.

How long does a proxy last? Eleven months unless the proxy states another term (§ 351.245).

Can a majority act by written consent? No. Section 351.273 requires every shareholder entitled to vote on the matter to sign.
