株式交付 (kabushiki koufu) — share-for-share acquisition regime under Japanese Companies Act 2021 revision

Wiki route

This entry sits under corporate-strategy INDEX and routes into finance INDEX for transaction-finance context. Read with Japan Kaisha Bunkatsu Tax Regime for the contrast against split-mechanism reorganizations, partial spinoff tax deferral for the distribution-side parallel, spinoff decision tree Japan for option-set context, and Japan tender offer process for the public-bid alternative.

TL;DR

株式交付 (kabushiki koufu) is a Japanese Companies Act mechanism introduced in the 2021 Companies Act revision (effective 2021-03-01) that enables a Japanese stock company to acquire another Japanese stock company’s shares using its own shares as consideration, while keeping the target as a subsidiary rather than a wholly-owned subsidiary. The acquirer issues new shares directly to selling shareholders of the target in exchange for target shares.

This sits between two pre-existing regimes:

• 株式交換 (kabushiki koukan, share exchange) — makes the target a wholly-owned subsidiary; requires 100% acquisition
• 株式移転 (kabushiki iten, share transfer) — creates a new holding company above existing entity; only used for HoldCo conversions

株式交付 fills the gap: it enables share-as-consideration acquisitions where the acquirer wants a controlling stake (e.g., 50-90%) without forcing 100% ownership. Tax treatment under specified conditions allows the selling shareholders to defer capital gains on the share exchange (limited to the share portion of consideration), making it economically equivalent to a US “B reorganization” in spirit.

1. Why The 2021 Regime Was Created

Pre-2021 problem: A Japanese acquirer wanting to use its own shares to acquire a Japanese target faced a procedural trap:

• 株式交換 required acquiring 100% of target — too aggressive when minority retention preferred
• Direct share issuance to selling shareholders (in-kind capital increase) was complex; tax treatment uncertain for sellers
• TOB + cash consideration possible but required cash from acquirer balance sheet
• TOB + share exchange (公開買付 + 株式交換) was a 2-step sequence with timing and tax friction

Result: cross-shareholding unwinding, friendly carve-out acquisitions, and PE-backed roll-ups where parties wanted share consideration were forced into awkward structures. The Ministry of Justice’s 2021 reform created 株式交付 to fill the gap explicitly.

2. Mechanism

Sources: mechanism and procedure follow the Companies Act; shareholder tax treatment follows NTA No.1545 and the Ministry of Finance summary. “Subsidiary” is a legal-control result, not a universal arithmetic shortcut independent of voting-right and control facts. ^[Sources: https://laws.e-gov.go.jp/document?lawid=417AC0000000086; https://www.nta.go.jp/taxes/shiraberu/taxanswer/shotoku/1545.htm; https://www.mof.go.jp/tax_policy/summary/corporation/c06.htm.]

3. Comparison Of Three Share-Side Reorganization Regimes

Sources: the legal outcomes are summarized from the Companies Act. Tax deferral is conditional and is not established merely by selecting one of these legal forms. ^[Sources: https://laws.e-gov.go.jp/document?lawid=417AC0000000086; https://www.mof.go.jp/tax_policy/summary/corporation/c06.htm.]

The decision tree:

• Want 100% ownership + share consideration → 株式交換
• Want to convert to HoldCo structure → 株式移転
• Want controlling stake (50-99%) + share consideration → 株式交付

For asset-level (vs share-level) reorganizations, see Japan Kaisha Bunkatsu Tax Regime.

4. Tax Treatment Mechanics

The selling shareholder receives acquirer shares plus possibly cash / bonds. Tax treatment splits:

Sources: the table is scoped to the shareholder deferral described in NTA No.1545 and the Ministry of Finance organization-restructuring summary. ^[Sources: https://www.nta.go.jp/taxes/shiraberu/taxanswer/shotoku/1545.htm; https://www.mof.go.jp/tax_policy/summary/corporation/c06.htm.]

Conditions for share-portion deferral include:

• Acquirer issues its own shares (not subsidiary shares) — direct issuance
• The target becomes the acquirer’s subsidiary under the statutory 株式交付
• Parent shares represent at least 80% of the total consideration value
• The post-transaction parent does not fall within the specified excluded family-company case

The 80% consideration test and excluded post-transaction family-company case are stated in those same sources.

5. Practical Use Cases

Sources: these are illustrative structure-selection hypotheses derived from the statutory mechanism, not claims about adoption frequency or named transactions. Availability still requires two Japanese stock companies and satisfaction of every legal, tax, disclosure, and competition condition. ^[Sources: https://www.moj.go.jp/MINJI/minji07_00214.html; https://laws.e-gov.go.jp/document?lawid=417AC0000000086.]

Note: 株式交付 is only available between Japanese stock companies. Cross-border share-for-share acquisitions still typically use the cross-border M&A Japan structures rather than 株式交付 directly.

6. Procedural Requirements

The 株式交付 procedure under Companies Act art. 774-2 through 774-11:

1. Acquirer prepares 株式交付計画 (share-delivery plan) specifying target, consideration ratio, terms
2. Acquirer board approves plan
3. Plan disclosed at acquirer head office for 2 weeks before shareholders’ meeting
4. Acquirer shareholders’ special resolution approves plan (2/3 threshold)
5. Solicitation of target shareholders to tender shares (each makes individual decision)
6. Tendering target shareholders agree to terms
7. Acquirer issues new shares to tendering target shareholders
8. Acquirer takes ownership of tendered target shares
9. Outcome: target is subsidiary if >50% shares tendered; if <50%, the 株式交付 fails

If the threshold is not met, the entire transaction is rescinded — there’s a “minimum tender” risk similar to a TOB minimum-tender condition.

7. Comparison With TOB-Plus-Squeeze-Out Path

Sources: this is a legal / consideration comparison based on the Companies Act, NTA tax guidance, and the general tender-offer route. It does not state that either path is available or superior for a particular issuer. ^[Sources: https://laws.e-gov.go.jp/document?lawid=417AC0000000086; https://www.nta.go.jp/taxes/shiraberu/taxanswer/shotoku/1545.htm; https://www.fsa.go.jp/policy/kaiji/tob/index.html.]

See Japan tender offer process for the TOB-side mechanism and Japan MBO / squeeze-out process for the post-TOB take-private route.

8. Comparison With 会社分割 + 株式分配 (Spinoff Path)

株式交付 is an acquisition mechanism (buying into a target). 会社分割 + 株式分配 (the kaisha bunkatsu + partial spinoff path) is a divestiture mechanism (separating an existing business). They occupy opposite sides of the corporate-reorganization map.

Sources: the table is a directional map of Companies Act mechanisms. Each row is subject to its own tax, securities, creditor, minority-holder, and approval rules. ^[Sources: https://laws.e-gov.go.jp/document?lawid=417AC0000000086; https://www.mof.go.jp/tax_policy/summary/corporation/c06.htm.]

9. Counterpoints

• 株式交付 has limited adoption since 2021 introduction relative to alternative paths — partly because cash-funded TOB remains the dominant Japan M&A pattern
• Tax-deferral conditions are technical; advisor-driven structuring required
• Acquirer share dilution may be unacceptable to existing shareholders even if procedurally feasible
• Foreign-acquirer-side cannot use 株式交付 directly (must work via Japan subsidiary or alternative structure)
• The “fails-if-below-50%” trigger creates execution risk that pure TOB doesn’t have (TOB can still execute at lower than-targeted tender amount in some structures)

10. Open Questions

• Will 株式交付 adoption increase as more Japan listed companies see it as a softer alternative to full-acquisition TOB?
• How will 株式交付 interact with future cross-border M&A reforms — could a parallel mechanism be created for foreign-acquirer use?
• What is the optimal hybrid structure for transactions that need partial cash + share consideration?
• How does the regime interact with post-acquisition minority shareholder protections (oppression remedies, dissenting-shareholder appraisal rights)?
• Will the regime see use in PE-backed Japanese acquisitions as a way to retain founder / management equity?
