Corporate Shareholder Preemptive-Rights Requirements in Michigan

At a glance

Requirements one by one

Identify the right's source and legacy branch

The ordinary Michigan rule is opt-in: the right must come from the articles or an agreement between the corporation and one or more shareholders. A shorthand election in either record activates subsection (2), subject to express variations (§ 450.1343(1)-(2)).

Rights created by statute or common law for shareholders of a corporation formed before January 1, 1973 survive the 1989 statutory system. The corporation may alter or abolish those legacy rights through an articles amendment (§ 450.1343(4)).

Apply allocation, coverage, and exclusions

The elected system gives proportional amounts of unissued shares on uniform board-prescribed terms designed to provide a fair and reasonable exercise opportunity. “Shares” includes a convertible security or one carrying a right to subscribe for or acquire shares (§ 450.1343(2)(a), (3)).

The system excludes compensation shares, shares satisfying compensation conversion or option rights, article-authorized shares issued within six months after incorporation, and shares issued for anything other than money (§ 450.1343(2)(c)).

Change or waive the right

A shareholder may waive the right, and a written waiver is irrevocable even without consideration. The articles or agreement may also vary the shorthand system's principles (§ 450.1343(2)).

An articles amendment may limit, deny, or grant a class's preemptive right. The ordinary post-issuance route requires board proposal and approval by a majority of outstanding shares entitled to vote; a class vote also applies when the amendment changes powers, preferences, or special rights so as to affect that class adversely (§ 450.1602(n); § 450.1611(3)-(5); § 450.1615(1)).

Reoffer declined shares

Unpurchased shares may be issued to another person within one year at board-set consideration no lower than the preemptive offer. A lower-consideration offer or an offer after the year expires is again subject to the shareholders' rights (§ 450.1343(2)(f)).

What trips people up

Michigan's agreement route is part of the statute's express source rule, not merely a generic contract caveat. The agreement may involve the corporation and one or more shareholders, and its express terms may vary the shorthand statutory principles (§ 450.1343(1)-(2)).

The six-month and one-year periods do different work. Six months defines the formation-period exclusion; one year governs the later issuance of declined shares to another person (§ 450.1343(2)(c)(iii), (f)).

Reacquired shares generally become authorized but unissued shares, but shares securing an unpaid purchase price do not reach that status until payment, and the articles may prohibit reissue (§ 450.1344(1)-(2), (4)).

Common questions

Do Michigan shareholders automatically receive preemptive rights?

Generally no. The articles or a qualifying agreement must provide the right, subject to the separate preservation rule for a corporation formed before January 1, 1973 (§ 450.1343(1), (4)).

Does the statute prescribe how many days the shareholder gets to respond?

No fixed exercise period appears in Section 450.1343. The board-prescribed terms must be uniform and provide a fair and reasonable opportunity to exercise the right.

Does the right apply to every class of shares?

No. Nonvoting preferred holders receive no statutory shorthand right, and a voting nonpreferred class ordinarily has no right as to preferred shares unless those preferred shares convert into or carry acquisition rights for nonpreferred shares (§ 450.1343(2)(d)-(e)).
