Corporate Shareholder Preemptive-Rights Requirements in Missouri

At a glance

Requirements one by one

Start with the default right and the articles

Missouri's operative rule is one sentence: “The preemptive right of a shareholder to acquire additional shares of a corporation may be limited or denied to the extent provided in the articles of incorporation” (§ 351.305). Section 351.055.2(2) likewise authorizes the articles to state the extent of any limitation or denial.

For an ordinary corporation that has received payment for shares, a later article amendment generally moves through board submission, written notice, and approval by a majority of the outstanding shares entitled to vote. If a class vote applies, the amendment also needs a majority of the outstanding shares of each entitled class (§ 351.090.2(1)-(3)).

Section 351.093 supplies separate class or affected-series voting when an amendment adversely alters the shares' powers, preferences, or special rights. It does not separately name preemptive rights, so the exact articles and class terms matter when applying that standard.

The statute leaves offer procedure to the corporate record

Section 351.305 does not prescribe proportional allocation, board-set or uniform terms, price or consideration, offer content, delivery, an exercise deadline, a record date, a waiver form, transaction exclusions, option or convertible coverage, treasury-share treatment, or a later issuance period. Those matters must come from the corporation's articles and other applicable corporate, contract, and securities law rather than another state's statute.

The appraisal language for a materially adverse preemptive-right amendment does not fill that gap for an ordinary corporation. Section 351.870 defines the corporation covered by Sections 351.870 through 351.930 as a statutory close corporation; Section 351.875.1(3)(c)'s appraisal event stays inside that special subchapter.

What trips people up

Missouri's default right is real even though Section 351.305 supplies almost no administrative detail. Silence about allocation, exclusions, or timing is not a charter opt-in rule and is not permission to import Model Act mechanics.

The articles may “limit or deny” the right. A limitation can therefore preserve some right while changing its scope; reviewing only whether the articles use a complete denial can miss the operative terms (§§ 351.055.2(2), 351.305).

Statutory-close-corporation appraisal is a special-entity rule. It should not be presented as the remedy for an ordinary Chapter 351 corporation (§§ 351.870, 351.875).

Common questions

Do Missouri shareholders start with preemptive rights?

Yes. Section 351.305 recognizes the right to acquire additional shares, subject to any limitation or denial in the articles.

Does Missouri prescribe how many days a shareholder gets to respond?

No. Section 351.305 states no notice or exercise period.

Does the statute cover options or convertible securities?

Section 351.305 speaks only of “additional shares” and does not define options, warrants, convertible securities, or subscription rights as covered.

Does an ordinary shareholder receive statutory appraisal if an amendment removes the right?

Not under Sections 351.870 through 351.930. Those provisions define their covered corporation as a statutory close corporation.
