How does shareholder voting work in M&A deals?

Question

AcadiFi · Accepted Answer

Shareholder voting requirements in M&A depend on deal structure, consideration type, and jurisdiction:

TARGET shareholder vote typically REQUIRED for:
- Statutory merger (target disappears into acquirer) — always
- Sale of substantially all assets — in most jurisdictions
- Stock-for-stock merger — yes

TARGET vote typically NOT required for:
- Tender offer where acquirer buys 90%+ then forces short-form merger (Delaware)
- Asset sales below 'substantially all' threshold

ACQUIRER shareholder vote typically REQUIRED for:
- Stock issuance exceeding 20% of outstanding shares (NYSE/Nasdaq listing rules)
- Deals where acquirer shares dilute existing holders meaningfully

ACQUIRER vote typically NOT required for:
- All-cash acquisitions (no new shares issued)
- Small stock deals below 20% threshold

THRESHOLDS:
- Simple majority of target shares outstanding (not just those voting) is the Delaware default
- Supermajority (2/3 or 80%) may be required under some charters or for going-private
- ISS and Glass Lewis proxy recommendations heavily influence institutional votes

FIDUCIARY OUT provisions let target boards change recommendation if a superior proposal emerges. A 'no-shop' clause with a fiduciary out is standard.

At the 2024 Brightwater Industries acquisition of Pinehurst Manufacturing, target shareholders approved the deal 89% in favor. Acquirer shareholders also voted because Brightwater issued 28% new shares to fund the stock portion.

For CFA Level II, recognize that voting requirements shape deal structure choices and timeline — tender offers with squeeze-outs are faster than statutory mergers.
