The Disciplines of M&A
Mandatory bids, board neutrality opt-outs, co-determination, golden shares and foundation defences — the rules that make a European or Asian target a different transaction from a US one.
A US or UK-trained dealmaker moving into continental Europe or Asia carries assumptions that do not travel. Delaware's fiduciary-duty case law and the UK Takeover Code's single, board-neutral rulebook are exceptions, not the template. Continental Europe runs on a directive that member states were free to gut, and the largest Asian markets each built takeover law around a different problem: Japan's around decades of defensive cross-shareholding, China's around capital controls and state ownership, India's around minority protection in a market still thick with promoter-controlled companies. What follows covers the structural facts a buyer needs before assuming a German, French, Dutch, Japanese, Chinese or Indian deal will behave like a US or UK one.
The Takeover Bids Directive (2004/25/EC) is the closest thing to an EU-wide takeover code, and it harmonised less than its name suggests. It mandates three things across all member states: a mandatory bid once an acquirer crosses a control threshold, an equitable-price rule for that bid, and squeeze-out and sell-out rights once an offer succeeds by a wide enough margin. It left two of its most consequential provisions optional. Article 9's board neutrality rule — barring target management from frustrating a bid without shareholder authorisation — and Article 11's breakthrough rule — nullifying multiple-voting-rights and share-transfer restrictions once a bid is on the table — were both opt-outs, and member states could also apply either on a reciprocal basis only, switching them off against bidders from states that had not adopted them themselves.
The mandatory bid: cross 30%, buy the rest
The result is that "the EU takeover regime" is a misnomer. A European Commission review found board neutrality transposed in full by 19 member states — including France, Italy and Spain, but notably not Germany or the Netherlands — while the breakthrough rule was adopted by only three: Estonia, Latvia and Lithuania (European Commission, 2012). Large-economy Germany and the Netherlands both declined board neutrality, which is precisely why German supervisory boards can bless defensive measures against a hostile bid and why Dutch companies retain the foundation-and-preference-share architecture described below. A buyer cannot assume EU membership implies UK-style passivity from a target's board.
Mandatory bid thresholds also diverge, even though most large jurisdictions converged near 30%:
| Jurisdiction | Mandatory bid threshold | Notes |
|---|---|---|
| Germany | 30% of voting rights | WpÜG, acting-in-concert aggregated |
| France | 30% of capital or voting rights | Also triggered by a 1-point increase within 12 months for holders already between 30% and 50% |
| Italy | 30% (25% for widely held companies with no shareholder above 30%) | SME issuers may set 25-40% by bylaw |
| Spain | 30% of voting rights | |
| Netherlands | 30% of voting rights |
(Baker McKenzie Global Public M&A Guide, 2025; the Italian bands reflect the country's 2024-2026 capital markets reforms, which reaffirmed the 30% core trigger.)
Squeeze-out and sell-out thresholds vary by mechanism as well as by country. Germany's takeover-specific squeeze-out under the WpÜG requires 95% of voting rights following the offer — a bar high enough that acquirers falling just short (commonly in the low-to-mid 90s) instead use the general corporate-law route under the Transformation Act, which needs only 90% of registered capital. France sets squeeze-out at 90% of both capital and voting rights. The Netherlands requires 95% of issued shares, tested separately in each share class where classes exist (Baker McKenzie, 2025).
German public companies are governed by a mandatory two-tier structure: a management board (Vorstand) that runs the business, and a supervisory board (Aufsichtsrat) that appoints, oversees and can dismiss it. A bidder does not negotiate with a unitary board that also manages the company; it negotiates with a Vorstand whose room to defend or recommend is itself supervised by the Aufsichtsrat, and Germany's opt-out from EU board neutrality means that board can approve defensive measures with supervisory board consent rather than simply staying passive.
The Aufsichtsrat itself is where US buyers most often underestimate the timetable. German co-determination law puts worker representatives on the supervisory board once headcount crosses statutory thresholds: one-third of seats at companies with 500 to 2,000 employees under the Drittelbeteiligungsgesetz, and full parity — half the board — above 2,000 employees under the 1976 Mitbestimmungsgesetz (a separate, older regime gives full parity in coal, steel and mining above 1,000 employees). Separately, the works council (Betriebsrat), operating under the Betriebsverfassungsgesetz, has statutory information and consultation rights whenever a transaction touches restructuring, headcount or working conditions — rights that do not block a deal outright but that require real negotiation (an Interessenausgleich on the substance of the change, often a Sozialplan on its social cost) before implementation can proceed cleanly. Treating these as a courtesy briefing rather than a negotiated process is the most common way a US buyer loses months it did not budget.
Beyond board approval and works council process, actual operational control over a German AG requires more than a majority stake. German corporate law otherwise insulates the Vorstand from shareholder instruction, so an acquirer that wants to direct the target's management and consolidate its results typically needs a domination agreement (Beherrschungsvertrag) and, usually alongside it, a profit-and-loss transfer agreement (Ergebnisabführungsvertrag). Together these let the controlling company issue binding instructions to management and pull the target's annual results into its own accounts; both require approval by 75% of the share capital represented at the shareholders' meeting (Jones Day, 2012). Without one, a majority owner can appoint the supervisory board but cannot lawfully direct day-to-day management. In outline, the WpÜG itself — administered by BaFin — sets the mandatory bid trigger at 30%, requires an offer document cleared by the regulator before publication, and gives the target's Vorstand and Aufsichtsrat a statutory obligation to issue a reasoned opinion on the offer.
France's takeover regime sits with the Autorité des Marchés Financiers (AMF), which clears offer documents and enforces the 30% mandatory bid threshold — with the same creeping-acquisition trigger noted above for holders already between 30% and 50%. Unlike Germany, France initially transposed board neutrality in full, then reversed course: the 2014 Florange Act suppressed the automatic neutrality obligation, allowing boards to take defensive measures without prior shareholder authorisation, while permitting companies to reinstate neutrality voluntarily in their bylaws — on a reciprocal basis, so protection lapses if the bidder itself does not observe neutrality (International Bar Association, cited via IBA analysis of the French board neutrality rule).
The same Florange Act is better known for a different change: automatic double voting rights for shares held continuously for at least two years, which came into force on 31 March 2016 for any company that had not opted out by that date in its bylaws (Compliance Week / FundApps, 2014-2016 reporting on the Loi Florange). The mechanism concentrates control with long-term holders — frequently a founding family or the French state — without requiring them to own a majority of the capital, and it is a standing feature a buyer must model into any French control calculus even absent a hostile scenario.
French labour law adds its own procedural layer: the works council (Comité Social et Économique, or CSE, which replaced the former comité d'entreprise) must be informed and consulted on a public offer for its employer and is entitled to render an opinion as part of the process, a requirement that runs in parallel with, not as a substitute for, the AMF's offer timetable. Separately, and covered on its own in the companion page on national-security and foreign-investment review, French inbound deals in sensitive sectors are also subject to the Bercy foreign-investment screening regime; that process is independent of, and does not replace, French takeover law.
Nordic public companies generally rely less on statutory devices than on capital structure itself: dual-class share systems (commonly A-shares with multiple votes and B-shares with one) let founding families and industrial groups retain control with a minority of the capital, a structure common across Sweden and, in different form, elsewhere in the region, and one that changes the practical mandatory-bid calculus more than any single statute does.
The Netherlands has built the most elaborate defensive toolkit in Europe, and it earns the description because it was built deliberately, over decades, as an alternative to board neutrality that Dutch law never adopted. The core device is the stichting continuïteit — an independent continuity foundation, typically chaired by figures with no operational role in the company — holding a call option over a large tranche of preference shares. On the emergence of a hostile approach, the foundation can exercise the option, issue itself the preference shares at a nominal price, and dilute the bidder's voting position quickly and substantially: when Carlos Slim's América Móvil pursued KPN in 2013, the company's foundation exercised its option and took a stake approaching half of KPN's voting rights, stopping the approach (Glass Lewis, 2016 analysis of Dutch continuity foundations). Dutch law layers a second defence on top: since 1 May 2021, a target's management board can invoke a statutory cooling-off period of up to 250 days under Article 2:114a of the Dutch Civil Code in response to a hostile bid or a shareholder move to oust the board, buying time to consult shareholders and consider alternatives (Bird & Bird, 2021).
The toolkit is not static. Shareholder activism has forced some companies to dismantle it voluntarily — Ahold Delhaize shareholders contested an extension of its call-option arrangement in 2018, and Fugro and Unilever have both wound down foundation structures under investor pressure (Glass Lewis, 2016 and subsequent reporting). A buyer approaching a Dutch target should confirm whether its foundation-and-preference-share architecture is still live before assuming a friendly path is the only one available.
Japanese takeover law changed more in three years than in the prior three decades. METI's June 2023 Guidelines for Corporate Takeovers replaced 2005-era guidance that had effectively licensed boards to treat almost any unsolicited approach as presumptively hostile. The new guidelines narrow the definition of corporate value used to judge a bid in its earliest stage to a quantitative standard — equity value plus net debt — rather than the open-ended qualitative factors (employee relationships, supplier ties, "corporate culture") that boards had previously invoked to justify resistance; centre "shareholders' intent" as the touchstone for whether defensive measures are legitimate, generally requiring shareholder approval rather than unilateral board action; and abandon the earlier preference for pre-emptive, standing defences in favour of measures adopted only once a specific bid has emerged and only if necessary and proportionate (Morrison Foerster, 2023). The practical effect has been to make an unsolicited approach to a Japanese public company a viable strategy rather than reputational suicide for the bidder.
Tender offers themselves are governed by the Financial Instruments and Exchange Act, and the trigger has itself just moved. For decades a purchase pushing an acquirer's stake above one-third of voting rights required a formal tender offer (TOB); a 2024 amendment lowers that threshold to 30% and extends the requirement to certain on-market transactions previously exempt, with the change taking effect on 1 May 2026 (DLA Piper, 2026). Alongside this, years of governance reform under the Tokyo Stock Exchange and the Corporate Governance Code have pushed listed companies and their bank and insurer counterparties to unwind cross-shareholdings — the network of mutual, defensively motivated equity stakes that historically insulated management from outside pressure — freeing up float and, not coincidentally, making hostile and unsolicited approaches more mechanically feasible than they were a decade ago.
The results are visible in deal flow. Nidec launched an unsolicited tender offer for Makino Milling Machine in April 2025 valued near $1.8 billion, contested it through Japan's Fair Trade Commission and the courts, and withdrew in May 2025 — a bid unthinkable from a Japanese strategic acquirer a decade earlier (Bloomberg, 2025). Alimentation Couche-Tard pursued Seven & I Holdings, owner of 7-Eleven, with a proposal reported near $47 billion before withdrawing in July 2025 citing insufficient engagement (CNBC, 2025). Japan Investment Corporation, a state-backed fund, took JSR Corporation, a major semiconductor-materials supplier, private via tender offer beginning in 2023 and completing in 2024, part of a take-private wave that also includes Toshiba's 2023 buyout by a Japan Industrial Partners-led consortium, and that marks a market newly comfortable with both foreign approaches and going-private structures.
Merger control in China runs through the State Administration for Market Regulation (SAMR); its notification thresholds and review process are covered in the companion page on merger control regimes. Two features specific to deal structuring in China deserve separate note here. First, acquisitions involving state-owned enterprises layer SAMR review with separate approvals from the entity's state or provincial ownership authority (commonly SASAC at the relevant level), a process with its own timeline and political-economy considerations that a commercial due diligence plan must budget for independently of antitrust clearance. Second, the variable interest entity (VIE) structure — a set of contracts, rather than direct equity, that route economic control of an operating company in a foreign-restricted sector (historically internet, media, telecoms and education) to an offshore holding vehicle, typically Cayman-incorporated and often US-listed — remains the standard route by which foreign capital accesses those sectors, and SAMR has in the past accepted merger filings involving VIE structures, giving the arrangement a degree of de facto regulatory recognition even though its legal status under Chinese company law has never been fully codified (Morrison Foerster, 2020).
On the outbound side, Chinese acquirers face a layered approval chain — the National Development and Reform Commission for large or sensitive outbound investments, the Ministry of Commerce for cross-border deal approval, and the State Administration of Foreign Exchange for currency conversion and remittance — and recent regulatory revisions have tightened full-lifecycle scrutiny of outbound deals, adding approval time and completion risk a foreign seller must price into deal certainty when the buyer is Chinese (Reed Smith, 2024-2025 reporting on China's outbound investment rules).
India's takeover regime centres on the SEBI (Substantial Acquisition of Shares and Takeovers) Regulations, 2011. An acquirer, together with persons acting in concert, that would cross 25% of voting rights must first make a public announcement of a mandatory open offer (Regulation 3(1)); that open offer must be sized for at least 26% of the target's total shares (Regulation 7(1)), a minimum designed to preserve a meaningful public float even after a change of control. A holder already at or above 25% is separately capped under the creeping-acquisition rule at acquiring no more than 5% of additional voting rights in any single financial year without triggering the same mandatory-offer obligation — measured on gross acquisitions and aggregated across persons acting in concert, so structuring around it through nominally separate buyers does not work (iPleaders, 2024 summary of SEBI Takeover Regulations).
Scheme-based mergers and demergers, by contrast, require approval from the National Company Law Tribunal (NCLT), and this is where Indian deal timetables diverge most sharply from US or European practice. The statutory target for an NCLT-approved scheme is 90 to 120 days; actual practice runs far longer. One analysis of roughly 3,400 merger filings made since 2021 found a median time from first filing to final order of nearly 13 months, extending to around 16 months for cases still pending, with one in four cases exceeding 19 months; timelines vary sharply by bench (roughly 20 months at Bengaluru versus roughly 10 months at Ahmedabad or Hyderabad), and cases drawing a regulatory objection add roughly six months on average (ThePrint, 2026). A buyer structuring an India transaction as a scheme of arrangement rather than a direct share purchase should treat "12 to 18 months to close" as the realistic base case, not the tail risk.
Crossing from a US deal into a German, Japanese or Indian one changes more than the applicable statute. In Germany, a buyer must budget real negotiating time with a works council and, if parity co-determination applies, accept that half the supervisory board answers to labour rather than capital — and must separately negotiate a domination agreement, at a 75% shareholder vote, before it can actually instruct management rather than merely elect its overseers. In France, the mandatory 30% threshold and 90% squeeze-out look familiar, but double voting rights mean the arithmetic of control does not equal the arithmetic of share count, and a CSE opinion process runs on its own clock alongside the AMF's. In the Netherlands, a friendly recommendation from the target board is not the same as an unencumbered path to control until the buyer has confirmed no continuity foundation stands ready to exercise a dilutive call option, and has priced in up to 250 days of statutory cooling-off if the approach turns hostile.
In Japan, the legal defence landscape flipped in 2023: an approach that once triggered near-automatic resistance can now proceed on its economic merits, under a tender-offer trigger newly lowered to 30% as of May 2026 — though Nidec's Makino bid and Couche-Tard's Seven & I approach both show a friendlier legal regime has not yet made large unsolicited Japanese deals reliably completable. In China, antitrust clearance is only one gate among several — SASAC approval for state-linked targets, VIE contractual structuring for restricted sectors, and an outbound approval chain for Chinese buyers that a foreign counterparty does not control and cannot accelerate. In India, the headline thresholds (25% trigger, 26% minimum offer, 5% annual creep) are precise and well understood, but the realistic closing timetable for anything routed through the NCLT — 12 to 18 months rather than the 90-to-120-day statutory target — is the single most consequential fact for deal planning, and the one most often modelled optimistically by first-time entrants.
The through-line across every jurisdiction above is that the mandatory-bid percentage is the easy number to find and the least useful one on its own. The consultation obligations, the defensive architecture actually available to a target board, the approval chains layered on top of merger control, and the realistic — not statutory — timetable are what determine whether a deal that pencils out on price actually closes on schedule.
