Corporate Merger and Share-Exchange Approval and Filing Requirements in Maine

At a glance

Requirements one by one

Maine separates the statutory plan from the public articles

For a merger, 13-C M.R.S. § 1102 requires a plan naming every party and the survivor, stating the transaction's terms and share or interest conversion, and supplying any new or amended survivor organic documents. The parallel rule in § 1103 uses the same architecture for a share exchange but identifies the acquired and acquiring entities and the classes or series being exchanged. Either plan may make terms depend on objectively ascertainable external facts under § 121(10).

The plan is not automatically the filed public record. The public-filing rule in § 1106 instead requires articles that recite the parties, entity types, jurisdictions, effective date, survivor amendments or new articles, approval or no-vote status, and any foreign-party authorization. The current MBCA-10 also asks where the executed plan is kept and states that the survivor will furnish a copy without cost to a constituent shareholder or participating-entity interest holder who requests it.

Board submission, recommendation, and holder approval are distinct

Section 1104 ordinarily requires the board to adopt the plan, submit it to the shareholders, and recommend approval. If conflicts, special circumstances, or § 827 make a recommendation inappropriate, the board must transmit the basis for proceeding without one. The board may condition submission on any basis.

The ordinary threshold is a majority of all votes entitled to be cast by each required voting group. The articles may set a lower threshold, but not below a majority of votes cast at a meeting where each group has a quorum of at least a majority of its entitled votes. A board condition or the articles may instead demand a greater vote.

Each converted class or series in a merger and each included class or series in a share exchange ordinarily votes separately. The articles may eliminate some of those separate-group rights only within § 1104(6-A)'s narrow boundaries; an amendment-equivalent change and the statute's consolidated-assets condition must still be tested.

Notice and written consent use different records and timing

If approval occurs at a meeting, § 1104(4) sends notice to every shareholder, including nonvoters. It must identify consideration of the plan as a purpose, include a copy or summary, and add the existing survivor's or new entity's organic documents when the merger structure calls for them.

Section 704 permits unanimous written consent by all voters. Nonunanimous meeting-minimum consent is available only if the articles authorize it. The needed consents must arrive within 60 days after the earliest signed consent; a consent may be revoked before sufficient unrevoked consents reach the corporation. Nonvoters and nonconsenting voters receive the required materials within 10 days after sufficient consents arrive or later tabulation finishes.

Maine also has an unusually broad unanimous route. Under § 1104(10), if all shareholders, whether or not entitled to vote, approve the plan by written consent, no board resolution is necessary and those holders have no statutory notice or dissent right for that plan.

The survivor or acquirer exception has two separate 20% tests

Section 1104(7) excuses only the surviving corporation's or share-exchange acquirer's holder vote, and only when every condition holds. The articles must not opt out; the corporation's articles may have no disallowed change; each existing holder must retain the same number of shares with identical rights; and both posttransaction voting-share issuance and participating-share issuance, including conversion and warrant effects, must stay within 20% of the respective premerger totals.

That exception does not excuse approval by another constituent or the acquired corporation. Section 1104(8) separately requires a written consent from every holder who would acquire personal owner liability through the transaction.

A 90%-owned subsidiary merger is a separate route

Under § 1105, a domestic parent holding at least 90% of the voting power of each voting class and series may merge a subsidiary into the parent or another qualifying subsidiary, or merge the parent into the subsidiary, without the subsidiary's board or shareholders approving. Contrary articles and the foreign subsidiary's governing law can restore subsidiary approval.

The parent must notify every subsidiary shareholder within 10 days after effectiveness when subsidiary approval was unnecessary. Other Chapter 11 rules continue to govern, so § 1105 is not a general waiver for the parent's own approval or the filing. The current Chapter 11 states no separate holding-company or tender-offer-follow-on merger route for this surveyed corporation.

Filing, amendment, abandonment, and records follow the approved plan

Section 1106 requires an officer or other duly authorized representative of each party to sign the articles; the survivor or share-exchange acquirer delivers them to the Secretary of State. Sections 121 and 125 do not require a seal, attestation, acknowledgment, or verification and make an accepted filing effective at filing, at a stated time that day, or at a delayed time and date no later than the 90th day after filing. The current official MBCA-10 fee is $100.

Sections 1102(6) and 1103(6) require the plan itself to authorize prefiling amendment. After holder approval, renewed approval protects merger consideration, survivor organic documents beyond the permitted amendment exception, and any materially adverse term; the share-exchange protections cover consideration and materially adverse terms.

Before effectiveness, § 1108 permits abandonment under the plan's procedure or, if none, as the board determines, subject to other parties' contract rights. If articles have already been filed, a party's officer or authorized representative must file the abandonment statement before the effective time. Section 1601 keeps meeting and written-action records permanently and the specified shareholder minutes, action records, and general communications at the principal or registered office for three years.

Appraisal is a conditional boundary, not an automatic result

Section 1302 conditionally covers a merger requiring § 1104 holder approval, a § 1105 subsidiary merger, and a share exchange for holders of the acquired corporation's exchanged class or series. Retained shares and the separate limitations in Chapter 13 can change eligibility.

Section 1321 requires the meeting or consent notice to say whether the corporation has concluded that appraisal rights are, are not, or may be available, and to include Chapter 13 when rights are or may be available. This page does not decide eligibility, value, demand compliance, or payment for a particular holder.

What trips people up

• A majority of votes cast is not Maine's automatic default. The ordinary § 1104(5) denominator is all votes entitled to be cast by each group. The votes-cast alternative exists only through the articles and carries its own majority-entitled quorum floor.
• The no-vote exception has two issuance calculations. Passing the voting- share test does not dispense with the separate participating-share test, and identical predeal holder rights plus the no-article-change condition still matter.
• Ordinary unanimous voter consent and unanimous all-holder consent are not the same route. Section 704 ordinarily speaks to all holders entitled to vote; § 1104(10)'s board-and-notice waiver requires every shareholder, including nonvoters.
• The official form adds practical filing fields. MBCA-10 asks for the survivor, the plan's record location and copy undertaking, approval status, effective date, party signatures, and any foreign or eligible-entity authorization. A commercial agreement alone does not supply that public filing record.

Common questions

May a written consent be revoked?

Yes, before sufficient unrevoked consents have been delivered. Section 704(2) also requires the complete sufficient set within 60 days after the earliest signed consent was delivered.

Does the parent-subsidiary route require 90% of all shares?

Section 1105 uses at least 90% of the voting power of each class and series that has voting power. The articles and, for a foreign subsidiary, its governing law can still require subsidiary approval.

Must the articles attach the private merger agreement?

Section 1106 lists recitals for the articles rather than requiring the private agreement as an attachment. The current MBCA-10 instead states that the executed plan or agreement is on file at the survivor's principal place of business and will be supplied without cost on request to the specified holders.
