Corporate Merger and Share-Exchange Approval and Filing Requirements in New Mexico

At a glance

Requirements one by one

New Mexico uses a plan of merger, consolidation, or exchange

NMSA 1978, § 53-14-1 governs a merger into a surviving domestic corporation, and NMSA 1978, § 53-14-2 governs a consolidation into a new corporation. NMSA 1978, § 53-13-13 separately authorizes another domestic corporation to acquire all issued or all outstanding shares of one or more classes through a plan of exchange. The same section preserves voluntary or agreed acquisitions that do not use the statutory exchange route.

Each statutory plan identifies the parties and survivor, acquirer, or new corporation; states the terms; specifies how shares convert or exchange into securities, obligations, cash, or property; and includes the required article treatment and other provisions.

Board action and holder submission depend on the party

For a merger or consolidation, every constituent board approves the plan. For an exchange, NMSA 1978, § 53-13-13 requires approval by both boards, but NMSA 1978, § 53-14-3 sends the holder vote to the corporation whose shares will be acquired. The acquiring corporation instead confirms board approval and any other requisite corporate action in the filing under NMSA 1978, § 53-14-4. These sections do not add a separate ordinary advisability declaration or board-recommendation requirement.

Notice, voting classes, and consent must be calculated separately

NMSA 1978, § 53-14-3 requires written notice to every record shareholder, voting or nonvoting, at least 20 days before the meeting. The notice must identify consideration of the plan as a purpose and carry the plan or a summary.

The default approval is a majority of all shares entitled to vote. A class votes separately if a plan provision would create an amendment class vote, and every class included in an exchange votes as a class. NMSA 1978, § 53-18-6 permits the articles to demand a greater proportion. NMSA 1978, § 53-18-6.1 also preserves the former two-thirds threshold for some corporations existing on June 17, 1983 until the statutory opt-in occurs.

NMSA 1978, § 53-18-8 permits action without a meeting only through written consent signed by all shareholders entitled to vote on the subject. It is not a meeting-minimum consent route.

The survivor and 90%-parent exceptions are different

Under NMSA 1978, § 53-14-3(D), the survivor skips its holder vote only if its articles differ at most in name, its existing holders keep the same number of shares with identical rights, and both voting-share and participating-share expansion stay within separate 20% ceilings.

NMSA 1978, § 53-14-5 is a different route. A parent owning at least 90% of every outstanding class may merge the subsidiary into itself without either corporation's holder vote. It must mail the plan to each subsidiary record holder and wait until the thirtieth day after mailing before delivery of the articles, unless every outstanding holder waives mailing. Article 14 states no separate ordinary holding-company or tender-offer merger route.

The filed articles disclose the plan and vote record

NMSA 1978, § 53-14-4 requires the articles to carry the plan, outstanding-share and class data, vote totals or the survivor no-vote statement, and the exchange acquirer's approval statement. Each merger or consolidation corporation executes through an authorized officer; the original and a copy go to the secretary of state, which returns a certificate with the file-stamped copy.

NMSA 1978, § 53-2-1 sets a capitalization-based filing fee with a $200 minimum and $1,000 maximum. Under NMSA 1978, § 53-14-6, the transaction takes effect on delivery unless the plan selects a later date no more than 30 days afterward.

Abandonment exists, but the statute does not supply a general amendment procedure

NMSA 1978, § 53-14-3(C) permits abandonment after holder approval and before filing only if the plan contains an abandonment provision. The complete merger and exchange sequence states no separate plan-amendment procedure, so an altered plan must be tested against the plan, governing documents, and the approval provisions rather than assumed to remain approved.

Dissent rights are transaction- and party-specific

NMSA 1978, § 53-15-3 covers a merger or consolidation party and the corporation whose shares are acquired in an exchange. It excludes survivor holders when the survivor did not need a vote. NMSA 1978, § 53-15-4 then imposes written-objection, no-favorable-vote, demand, certificate, payment, and court steps. Eligibility and preservation therefore require a separate appraisal analysis.

What trips people up

The exchange route covers all issued or all outstanding shares of one or more classes. A voluntary purchase of fewer shares may still be lawful by agreement, but it is not automatically the statutory plan-of-exchange procedure.

New Mexico's simple-majority text does not safely answer the vote for every corporation. Formation date, later article amendments, public-company history, and any articles-set greater threshold must be checked before counting approvals.

Common questions

Do the acquiring corporation's shareholders vote on a share exchange?

The exchange statute requires both boards, but sends the transaction-specific holder vote to the corporation whose shares are acquired. NMSA 1978, § 53-14-4 still requires the filing to state any other requisite corporate action for the acquirer.

Can unanimous written consent replace the 20-day meeting process?

Yes, if all shareholders entitled to vote sign the written consent required by NMSA 1978, § 53-18-8. A bare majority consent does not satisfy that section.

Does 90% ownership eliminate all notice?

No. NMSA 1978, § 53-14-5 removes both corporations' shareholder votes, but requires mailing the plan to every subsidiary record holder and ordinarily delays filing for 30 days.
