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

At a glance

Requirements one by one

The acquired corporation, not the acquirer, submits a share exchange

Indiana Code §§ 23-1-40-1 to -2 require each corporation's board to adopt the merger or exchange plan. For a merger, every party's board submits the plan to its holders unless the survivor exception applies. For a share exchange, § 23-1-40-3(a) requires submission by the corporation whose shares will be acquired, not by the acquiring corporation. The acquirer's board still adopts the plan.

The plan names the parties and survivor or acquirer, states the terms, and describes conversion or exchange into shares, obligations, securities, cash, or property. Survivor-article amendments are optional plan terms in Indiana, not a mandatory attachment to every plan.

Notice, consent, and the vote denominator must be kept separate

At a meeting, § 23-1-40-3(d) sends every shareholder the notice and plan or summary. Section 23-1-29-5 supplies the 10-to-60-day meeting window. Unless a higher requirement applies, § 23-1-40-3(e)-(f) uses a majority of all votes entitled to be cast by each group. A merger gets a separate group for an amendment-equivalent plan provision; every class or series included in a share exchange is a separate group.

For an ordinary private corporation, § 23-1-29-4(a)-(f) allows the meeting- minimum written-consent route unless the articles provide otherwise. The consents must reach the corporation within 60 days of the earliest signature, and nonvoting and nonconsenting holders receive the required post-action notice. That nonunanimous default does not extend to an Exchange Act reporting class.

Proportional ownership and both 20% caps control the survivor exception

Section 23-1-40-3(g)-(h) excuses only the surviving corporation's merger vote. Its articles must remain unchanged except for permitted amendments, and each continuing holder must retain the same proportional ownership with identical share terms, subject to the statutory treatment of shares received through other constituents. The voting-share and participating-share totals each count transaction issuances, rights, and warrants and each must stay within 20% of the split-adjusted premerger base.

This is not an acquirer-cap rule for share exchanges. The acquirer's ordinary no-submission result comes from § 23-1-40-3(a), while the acquired corporation's holders vote by class or series.

The 90% parent and holding-company routes are separate

Under § 23-1-40-4, a parent holding at least 90% of every outstanding subsidiary class may merge parent and subsidiary without either holder vote. The parent must mail the plan or summary to nonwaiving subsidiary holders and wait at least 30 days before filing.

Section 23-1-40-9 supplies a distinct board-only holding-company reorganization. It requires a wholly owned structure, equal replacement equity, specified Indiana entity forms, substantially identical governing documents and boards, the continuing downstream-approval protections, and the board's federal tax nonrecognition determination. A secretary or assistant secretary certifies the statutory conditions in the Articles. That statutory route does not itself give tax advice or guarantee federal treatment.

Indiana's Articles are approval-focused, not the whole plan

Section 23-1-40-5 requires the survivor or acquirer to file Articles naming the post-transaction corporation and stating either that no holder approval was required or the separate-group capitalization and vote results. It does not require the public Articles to restate the entire plan. Section 23-1-40-6(c) treats plan terms outside the surviving articles as contract rights rather than governing-document terms.

Under §§ 23-0.5-2-1(a) and 23-0.5-2-3, an authorized person signs without a seal, attestation, acknowledgment, or verification. Effect occurs on filing or at a stated later time, with a delayed date capped at 90 days.

Prefiling amendment is broad, but filing changes the mechanism

Section 23-1-40-3(i)-(j) allows abandonment or amendment before Articles are filed under the plan procedure or, if none, the board's method. The amendment subsection does not itself state a renewed-holder-vote rule, so a material postapproval change should not be treated as automatically safe without checking the approved plan, articles, contracts, and complete corporate record.

Once the Articles are filed but have not taken effect, § 23-0.5-2-4 uses a filed statement of withdrawal rather than Chapter 40's prefiling abandonment step. The signers or their agreement control the withdrawal signature rule.

Dissenters' rights are a separate Chapter 44 procedure

Sections 23-1-44-8 and 23-1-44-10 connect rights to a merger holder who was entitled to vote when holder approval was required, and to an acquired-company holder entitled to vote on a share exchange. Covered securities and permitted preferred-share provisions can remove or limit those rights, and the meeting or no-vote route changes the notice. Approval and filing do not themselves preserve a claim or resolve valuation, fiduciary, securities, antitrust, tax, creditor, contract, or regulatory work.

What trips people up

Indiana does not require the share-exchange acquirer's holders to approve merely because its board adopts the plan. The merger survivor exception is based on proportional ownership and two separate split-adjusted 20% tests. The 90% parent route adds a 30-day mailing wait, while the holding-company route has a much longer condition list. Finally, the public Articles report approval facts rather than reproducing the transaction plan.

Common questions

Does a share exchange end the acquired corporation's existence?

No. Section 23-1-40-6(b) exchanges the acquired shares and leaves former holders with the plan rights or any Chapter 44 rights. It does not apply the merger rule that ends every nonsurvivor's separate existence.

What happens to property and liabilities in a merger?

When the merger takes effect, § 23-1-40-6(a) vests each party's property in the survivor, assigns each party's liabilities to it, and permits pending proceedings to continue or substitute the survivor. Contract consents, liens, licenses, tax, and regulatory consequences remain separate.

May a foreign corporation participate?

Yes, within § 23-1-40-7. A foreign merger party must be permitted to merge by its own jurisdiction, while a foreign acquirer may acquire an Indiana corporation's shares under Indiana's share-exchange rule. Each domestic corporation still follows the applicable Indiana approval provisions.
