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

At a glance

Requirements one by one

Start with the statutory plan, not the commercial agreement

Texas uses a written plan of merger or plan of exchange. For a merger, the plan identifies every party and survivor or new organization, organizational forms and jurisdictions, how each interest converts, exchanges, cancels, or remains outstanding, and the cash, securities, rights, property, or combination used as consideration. New-entity formation documents belong in the plan when applicable (§§ 10.001-.002).

An interest exchange is the statutory route for acquiring all outstanding interests of one or more classes or series. Its plan names the acquired and acquiring organizations, identifies the interests each acquirer receives, states the terms, and states the consideration formula (§§ 10.051-.052).

Both plan statutes require differential same-class or same-series treatment to be stated and permit outside facts only when the plan clearly explains their operation. Disclosure letters and schedules are not part of the statutory plan unless the plan expressly says otherwise.

Board action, holder notice, and holder approval are separate steps

For each merger constituent, § 21.452 requires a board resolution approving the plan. If shareholders must approve, the board recommends approval or submits without recommendation and communicates its reason; it may condition submission and may later recommend against. Section 21.454 applies the parallel structure to the corporation whose shares will be acquired in an interest exchange.

The 2025-enacted § 3.106 now permits a governing authority to approve a document in final or substantially final form and to ratify it before the related filing becomes effective. That does not erase the transaction-specific shareholder, class, notice, or filing steps.

For a meeting, § 21.456 requires notice to every shareholder, including a nonvoting holder, no later than the 21st day before the meeting. The notice must state the transaction purpose, contain or accompany the plan or a summary, and carry the § 10.355 appraisal notice.

The ordinary denominator is outstanding shares, with separate class votes

The default § 21.457 threshold is at least two-thirds of all outstanding shares entitled to vote, not two-thirds of votes cast or shares present. Each class or series entitled to vote separately also ordinarily supplies two-thirds of its outstanding shares.

Section 21.458 gives a merger class or series a separate vote if its shares convert or exchange, the plan contains an amendment-equivalent provision, or the certificate grants that vote. For an exchange, each class or series being exchanged votes separately, as does one with a certificate-granted vote. Nonvoting holders still receive the § 21.456 meeting notice.

Written consent has a different notice calendar

Section 6.201 permits unanimous written consent by default. Less-than-unanimous consent is available only if the certificate of formation authorizes it, and the signed votes must equal the meeting minimum. Section 6.202 requires dated consents, ordinarily completes the necessary signatures within 60 days, permits revocation before effectiveness, and requires prompt notice to record-date owners who did not sign.

Advance meeting notice does not carry over to consent (§ 6.204), but appraisal notice does. Section 10.355 requires it before a consenting owner delivers the consent and, for an entitled nonconsenter, before the 11th day after the action takes effect. Electronic consent can qualify as a signed writing when § 6.205's identity and date information is present.

Test each no-vote or specialized route on its own facts

The ordinary survivor exception in § 21.459(a) requires every condition: sole survivorship; no certificate change; unchanged number and rights of each premerger shareholder's shares; and no more than a 20% increase under both the voting-power and participating-share calculations, including the specified convertible or exercisable securities. The certificate of formation may still require a vote.

The holding-company route in § 10.005 is more detailed than a simple wholly owned-subsidiary test. It also requires same organizational form, substantively identical holder rights and governing documents subject to stated exceptions, continuing governing persons, the specified federal-tax findings, and a governing-authority resolution.

Under § 10.006, a parent owning at least 90% of every outstanding class and series may use the short-form route. A domestic subsidiary takes no approval action. A nonsurviving parent follows the ordinary parent-approval route; a surviving parent uses a governing-authority resolution with the required terms. Section 21.459(c)-(f)'s listed-or-2,000-holder offer-followed-by-merger procedure is a separate public-company boundary, not the ordinary private-company route.

The public certificate controls statutory effectiveness

Under §§ 10.151-.153, a certificate of merger or exchange is required when a Texas filing entity is a merger party or new entity, or when interests in a filing entity are acquired. An officer or authorized representative signs for each party. The filing attaches the plan or uses the statutory alternative statements, including parties and jurisdictions, formation changes, plan locations and a free-copy promise, any no-owner-vote statement, and an approval statement.

The filing goes to the Secretary of State for an ordinary corporation. Form 622 is the current general merger form; its instructions direct a § 10.006 short-form merger to Form 623 and list a $300 filing fee plus formation fees for new filing entities.

A required filing makes the merger or exchange effective on acceptance unless the certificate validly specifies a later date, time, or future event. The delayed-effective date cannot exceed 90 days after signing, and a future-event route requires the follow-up statement described in the general filing rules, §§ 4.051-.057. The transaction-specific rules, §§ 10.007 and 10.054, supply the merger- and exchange-specific acceptance rule.

Abandonment, records, and appraisal remain separate

After approval but before effectiveness, § 10.201 permits a domestic party to abandon without owner action under the plan's procedure or, if none, in the manner its governing authority determines, subject to contractual rights. Once the certificate has been filed, §§ 4.057 and 10.202 require a signed certificate of abandonment before effectiveness. Under §§ 10.004(b) and 10.053(b), owner-representative provisions may make specified plan terms unamendable after effectiveness or amendable only with named consent or approval. Under § 3.151, the corporation must separately keep account books, ownership records, and minutes of owner and governing-authority proceedings.

Subchapter H appraisal eligibility is conditional. Sections 10.351 and 10.354 turn on the transaction, whether approval was required, the affected class or series, market or holder-count status, equal treatment, consideration, and the short-form or offer-merger branch. Sections 10.355-.368 then impose notice, objection, demand, payment, and court steps. This page identifies that boundary; it does not decide entitlement, fair value, or preservation for a particular holder.

What trips people up

• The two-thirds vote is measured against outstanding shares. Abstentions and absent shares can therefore matter differently than under a votes-cast formula, and a required class or series repeats the outstanding-share test.
• Nonvoting does not mean no notice. Section 21.456 sends the meeting notice to every shareholder; voting rights are separately determined under §§ 21.457-.458.
• The 20% survivor exception has two calculations. Satisfying only the voting-power cap does not satisfy the participating-share cap.
• Form 622 is not the short-form filing. The Secretary of State instructions direct a § 10.006 parent-subsidiary merger to Form 623.
• A future-event filing needs a second filing. Without the timely § 4.055 event-or-fact statement, § 4.056 says the original filing does not take effect.

Common questions

Must a Texas merger board always recommend approval?

No. Section 21.452 permits submission without a recommendation, but the board must communicate why it made that choice. It may also later submit the plan with a recommendation against approval.

May shareholders approve a merger by electronic consent?

Potentially. The consent route must first be available under §§ 6.201-.205, and § 6.205 treats an electronic transmission as a signed writing when the required sender and transmission-date information can be determined, unless the governing documents provide otherwise.

Does the acquiring corporation's shareholder body always vote on an interest exchange?

Not under the exchange provisions merely because it is the acquirer. Section 10.051 requires each acquiring domestic entity to take whatever other action the Code and its governing documents require; § 21.454's exchange vote applies to the corporation whose shares are being acquired.

Does Secretary of State acceptance prove the transaction was fair?

No. Section 10.156 addresses conformity and franchise-tax acceptance. It does not adjudicate fiduciary fairness, valuation, contract compliance, securities, antitrust, tax, creditor, or regulatory requirements.
