Corporate Stock-Transfer Restriction and Certificate-Legend Requirements in Iowa

At a glance

Requirements one by one

Authorized records and earlier-issued shares

Iowa Code § 490.627(1) permits a restriction in the articles of incorporation, bylaws, an agreement among shareholders, or an agreement between shareholders and the corporation. A share issued before adoption is unaffected unless its holder is a party to the restriction agreement or voted for the restriction.

For this section, “shares” includes a security convertible into or carrying a right to subscribe for or acquire shares (§ 490.627(5)). The actual instrument must fit the statutory authorization and the earlier-share party-or-vote gate.

Permitted purposes and forms

Section 490.627(3) authorizes restrictions used to maintain a corporate status dependent on shareholder number or identity, preserve a federal or state securities-law exemption, or serve another reasonable purpose.

The permitted forms are a first offer to the corporation or other people; an obligation for the corporation or other people to acquire the shares; approval by the corporation, holders of any class or series, or other people; and a prohibition involving designated people or classes. The offer and acquisition routes may operate separately, consecutively, or simultaneously. Approval and designated-person terms must not be manifestly unreasonable (§ 490.627(4)).

The surveyed provision does not separately prescribe an ownership percentage cap, automatic-transfer mechanism, tax-attribute route, purchase price, valuation formula, funding method, or remedy.

Certificate and uncertificated-share notice

An authorized restriction is valid and enforceable against the holder or the holder's transferee when its existence is noted conspicuously on the front or back of the certificate or included in the written information statement for uncertificated shares. Without that notice, it is not enforceable against a person without knowledge of the restriction (§ 490.627(2)).

Section 490.626 lets the board authorize some or all classes or series without certificates unless the articles or bylaws provide otherwise. Existing certificated shares remain in that form until surrender. Within a reasonable time after an uncertificated issuance or transfer, the corporation delivers the shareholder the applicable certificate and restriction information.

What trips people up

Earlier-share assent and transferee notice are separate gates. Party status or a favorable vote determines whether an after-adopted restriction affects an earlier-issued share. Certificate or information-statement notice, and the person's knowledge, determine enforcement against a later person (§ 490.627(1)-(2)).

A class or series approval term still has a statutory limit. The restriction may assign approval to holders of any class or series, but the requirement must not be manifestly unreasonable (§ 490.627(4)(c)).

The corporate notice is not a universal securities legend. Preserving a federal or state securities-law exemption is an authorized purpose. Federal and state restricted-securities notices, UCC Article 8, intermediary systems, and transfer-agent procedure remain separate.

Common questions

May an Iowa restriction appear in the bylaws?

Yes. Section 490.627(1) expressly names the bylaws, along with the articles and the two shareholder-agreement routes. The earlier-share party-or-vote rule still applies.

May Iowa require the corporation to buy restricted shares?

Yes. Section 490.627(4)(b) permits a restriction obligating the corporation or other people, separately, consecutively, or simultaneously, to acquire the shares. It does not set the trigger, price, valuation method, funding, or remedy.

Does the statute reach convertible securities?

Yes. Section 490.627(5) includes a security convertible into or carrying a right to subscribe for or acquire shares.

Can Iowa shares be issued without certificates?

Yes, unless the articles or bylaws provide otherwise. Section 490.626 preserves existing certificates until surrender and requires the written information statement after an uncertificated issuance or transfer.
