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

At a glance

Requirements one by one

Oregon separates the merger and exchange plans

ORS § 60.481 requires a merger plan to identify every party and the survivor, summarize material terms, and state how each ownership interest converts into interests, obligations, cash, or other property. The plan may amend a corporate survivor's articles. ORS § 60.484 instead requires both exchange boards to adopt a plan identifying the acquired and acquiring corporations, material terms, and the exchange basis.

Approval uses all entitled votes, not votes cast

Under ORS § 60.487, every merger-party board and the acquired corporation's board directs submission when a shareholder vote is required. The corporation notifies voting and nonvoting holders under ORS § 60.214, ordinarily 10 to 60 days before the meeting, and delivers the plan or a summary.

At a board meeting, ORS § 60.351 ordinarily requires a quorum and the affirmative vote of a majority of directors present, unless the articles or bylaws require more.

Each separately entitled voting group approves by “a majority of all the votes entitled to be cast,” not merely a majority of votes actually cast. A merger group with amendment-equivalent rights ordinarily votes separately, subject to the liquidation-value and article exceptions. Every class or series included in a share exchange is its own voting group.

Written action changes the timing of nonvoter notice

ORS § 60.211 defaults to unanimous written shareholder consent. The articles may instead authorize the minimum vote that would approve at a meeting with every eligible vote present. Unanimous action requires nonvoter notice and meeting- equivalent materials at least 10 days before action; qualifying nonunanimous action triggers prompt notice afterward to nonvoters and nonconsenters.

The survivor exception has two independent 20% tests

The surviving corporation avoids its shareholder vote only if its articles have no change beyond listed board-only amendments, each continuing holder retains the same number and kind of shares, and both post-merger calculations stay within 20%. One calculation covers voting shares and merger-issuable voting shares; the other separately covers participating shares and merger-issuable participating shares.

The 90% route works in either direction

ORS § 60.491 permits a parent owning at least 90% of every outstanding subsidiary class to merge the subsidiary into the parent or the parent into the subsidiary without either shareholder vote. A parent survivor may make only listed board- only article amendments. A subsidiary survivor must preserve each former parent holder's percentage and share rights, use parent-identical articles subject to those amendments, and remain domestic.

The notice is post-effective: within 10 days after effectiveness, the parent notifies the holders specified for that direction and mails the plan or summary to each holder who did not waive mailing.

The filing may use a declaration instead of publishing the plan

The survivor or acquirer delivers Articles of Merger or Share Exchange naming the parties and survivor or acquisition pair. It also files either the plan or a declaration identifying the office where the plan is held and promising a free copy on request, plus declarations addressing required approvals.

ORS § 60.004 permits the chair, president, another officer, or an authorized agent to execute the filing and requires the signer's identity declaration, name, and capacity.

Under ORS § 60.011, the filing is effective when filed at its stated time, or at 12:01 a.m. if no time is stated. A delayed effective date cannot be later than the 90th day after filing. A noncorporate party's statute can push effectiveness later.

Approval can be abandoned, but the records remain

ORS § 60.487(9) permits abandonment after authorization and before the Articles are filed, subject to contractual rights and the plan's procedure or the board's chosen procedure. ORS § 60.771 separately requires permanent records of board and shareholder meetings and actions without a meeting, plus three years of shareholder minutes, consent records, and general communications at the principal or registered office.

Appraisal notice is a separate workflow

ORS § 60.554 identifies possible dissent rights for qualifying merger and acquired-corporation exchange holders, subject to the national-exchange exclusion unless the articles provide otherwise. ORS § 60.561 requires the meeting notice to state that rights are or may be available and to include the complete dissenters' rights provisions; a no-vote transaction instead triggers written post-action notice to eligible holders.

What trips people up

• The ordinary approval denominator is every vote entitled to be cast by the group. Abstentions therefore do not disappear from the denominator.
• The two 20% survivor calculations protect different share features; passing the voting-share calculation does not establish the participating-share test.
• The 90%-parent notices follow effectiveness rather than serving as the ordinary premeeting notice.
• Filing a declaration can keep the plan itself out of the filing, but it does not replace the Articles or the approval declarations.

Common questions

May the boards act by written consent?

Yes, unless the articles or bylaws provide otherwise, but ORS § 60.341 requires all directors to sign written consents that describe the action and enter the corporate record.

Does consenting to shareholder action preserve dissenters' rights?

No. ORS § 60.211(6) preserves possible rights for a nonconsenting shareholder, but states that a shareholder who consents in writing is not entitled to payment under the dissenters' rights provisions.

Must the public filing contain the complete plan?

Not necessarily. ORS § 60.494 permits the plan to be replaced in the filing by the office-address and free-copy declaration, while still requiring the Articles and approval declarations.
