Requirements one by one
Missouri's ordinary Chapter 351 transaction is a merger, not a share exchange
The current Chapter 351 index and merger subchapter provide merger and consolidation procedures but no general statutory corporate share exchange. Under § 351.410, each constituent board approves the merger plan and directs submission to a shareholder meeting. The plan identifies the constituents and survivor, states the terms and mode, describes the conversion consideration, and states survivor-article changes and other desired provisions.
That structure should not be converted into a share-exchange answer by analogy. A stock acquisition, voluntary exchange, regulated-company transaction, or cross-entity combination needs its own current authority and transaction record.
Every ordinary constituent uses the two-thirds route
Under § 351.420 and § 351.425, each ordinary constituent must submit the plan and obtain at least two-thirds of all outstanding shares entitled to vote. There is no ordinary survivor no-vote, issuance-cap, or no-shares exception in the current merger subchapter. Section 351.270 lets the articles or shareholder- adopted bylaws require a greater portion or class or series concurrence, but the statute does not authorize a lower ordinary merger vote.
Meeting notice ordinarily runs 10 to 70 days. The merger notice states the purpose and includes the plan or a summary. Section 351.455.3 expands that purpose notice to every record-date stockholder, including a nonvoting holder, because the ordinary appraisal route is not limited to voting stock.
Unanimous consent and appraisal do not fit together automatically
Section 351.273 allows action without a meeting only when all shareholders entitled to vote sign, and the secretary files the consents with the shareholder- meeting minutes. Section 351.455, however, conditions ordinary appraisal on a meeting record date, a written objection before or at that meeting, and—for a voting holder—no favorable vote. A corporation should not assume the general consent statute eliminates or rewrites those appraisal steps.
The 90% parent route has a parent-nonsurvivor fork
Section 351.447 starts at 90% of every outstanding subsidiary class. When the parent is not the survivor, the route requires either a two-thirds parent vote or the alternative board approvals plus equal shareholder rights and benefits, survivor solvency, and retention of the parent's name. A minority-owned domestic subsidiary sends post-effective notice within 10 days and has the section's separate value-demand path.
Section 351.448 is a different board-only holding-company reorganization. It requires the two-constituent wholly owned structure, equal replacement shares, Missouri entities, substantially identical governing documents and directors, the downstream shareholder-approval provision, and the board's federal tax nonrecognition determination. Its Articles carry the board resolution and plan, and ordinary § 351.455 appraisal does not apply. The statutory tax condition is not a promise of federal treatment.
Summary Articles point to the private plan
Under § 351.430 and § 351.435, the survivor files Summary Articles with the constituent jurisdictions, approval statement, effective date, survivor, article changes, address where the executed plan is kept, and a statement that any constituent shareholder may receive the plan without cost. The Secretary keeps the filing and issues a Certificate of Merger.
Under § 351.046 and § 351.048, the chair, president, or another officer signs and states name and capacity; acknowledgment is optional. The merger takes effect on filing or on a specified delayed date no later than day 90 after filing.
Chapter 351 does not supply a modern amendment-and-abandonment workflow
The ordinary merger provisions contain no current general procedure governing plan amendment or abandonment; former § 351.440 is repealed. The plan may carry other desired provisions under § 351.410(5), the filed Summary Articles disclose where the executed plan is retained, and § 351.455.6 says appraisal rights cease if the corporation abandons the merger. Those provisions do not answer who may change or stop the transaction after holder approval or after filing, so the approved plan, governing documents, contracts, filing posture, and current Secretary procedure must be checked before acting.
Appraisal is a separate and deadline-sensitive remedy
Section 351.455 requires record-date ownership, a written objection before or at the meeting, no favorable vote for voting stock, and a written fair-value demand within 20 days after effectiveness. Its remedy is exclusive when available except for fraud or lack of authorization. Approval and filing alone do not preserve appraisal or decide valuation, fiduciary, securities, antitrust, tax, creditor, contract, or regulatory questions.
What trips people up
Missouri has no ordinary survivor exception and no general share-exchange statute in Chapter 351. Its two-thirds denominator is outstanding shares entitled to vote, not votes cast. Unanimous consent exists, but the appraisal statute is written around a meeting. And the public Summary Articles do not replace the executed plan: they identify where the plan remains on file and promise shareholders a free copy.
Common questions
What happens to the disappearing corporation's property and liabilities?
Section 351.450 ends every nonsurvivor's separate existence, transfers its property and interests to the survivor without another deed, and makes the survivor responsible for constituent liabilities. It preserves creditor rights, liens, and pending proceedings; contracts, licenses, tax, and regulatory work remain separate.
May a foreign corporation participate?
Yes, under § 351.458 when every foreign party's home law permits the merger and each party follows its governing approval law. A foreign survivor also accepts Missouri process and dissent-payment obligations through the statutory filing.
Does the Secretary's certificate establish that the merger is fair?
No. Section 351.435 describes filing and issuance of the certificate. They do not decide fiduciary compliance, valuation, conflicts, contract rights, tax, securities, antitrust, creditor protection, or regulatory approval.
