This analysis focuses on negotiated (friendly) acquisitions and does not cover hostile takeovers or proxy fights.
The acquisition of a controlling stake in a Belgian public company is subject to significantly more regulation than that of a private company.
Public company takeovers are governed by the Belgian Takeover Law (implementing the EU Takeover Directive) and monitored by the FSMA. A mandatory public offer must be launched when a shareholder (alone or in concert) acquires more than 30% of voting rights in a Belgian listed company (or 50% for companies listed on Euronext Growth or Access).
Disclosure requirements are also more stringent. In public deals, both the crossing of 5% thresholds (and each 5% increment) and price-sensitive information (e.g., a binding takeover agreement) must be disclosed to the market, unless a temporary exemption applies. In contrast, private deals remain confidential and are governed solely by the Belgian Companies and Associations Code.
Public takeovers also require equal treatment of shareholders: all must receive the same price in a tender offer. By contrast, in private transactions, different terms may be freely negotiated with individual sellers, and minority rights depend on contractual protections such as tag-along clauses.
The process and timing also differ. Public takeovers follow a regulated calendar: the offer must be approved by the FSMA, and the bidder must have “certain funds” (secured financing or a bank guarantee). The target’s board is restricted in its defensive actions. Private acquisitions allow flexible timing and funding conditions are set by contract.
Finally, corporate governance obligations are stricter in public deals. The board must publish a reasoned opinion on the bid, and directors must act in the interests of all stakeholders. In private companies, changes of control may be simpler but can still be constrained by bylaws or shareholder agreements.
M&A transactions in Belgium, whether private or public, typically involve several key documents.
At the preliminary stage, parties usually enter into a Non-Disclosure Agreement (NDA) and may sign a Letter of Intent or term sheet outlining principal terms. These are common to both private and public deals (excluding hostile transactions).
In private share deals, the main contract is a Share Purchase Agreement (SPA) covering purchase price, representations and warranties, conditions precedent, indemnities, and closing mechanics. For asset deals, an Asset Purchase Agreement governs the transfer of selected assets and liabilities. In case of mergers, key documents include the merger proposal, shareholders’ resolutions, and where applicable, an independent expert report, in accordance with the Belgian Companies Code.
Ancillary closing documents include updated share registers (Belgian law requires share transfers to be recorded in the shareholders register), board resolutions, and transfer instruments (e.g., notarial deeds for real estate or IP assignments).
Public acquisitions require additional regulated documents. The bidder must publish an Offer Document (offer prospectus), approved in advance by the FSMA, disclosing all terms of the offer, financing, and pricing. The target board must issue a response memorandum with its opinion. These are supplemented by press releases and regulatory announcements, including the FSMA’s disclosure of the intention to bid and final results. If the bidder reaches the 95% threshold, additional documents are required for a squeeze-out and potential delisting.
After closing, completion memoranda or settlement instructions are often executed.
In short, while private deals rely on freely negotiated documentation, public transactions must comply with regulatory formats and disclosure rules, resulting in significantly heavier documentation requirements.
In Belgium, public companies must disclose “inside information” under the EU Market Abuse Regulation (MAR). A contemplated acquisition or change of control will qualify as inside information if it would likely influence the share price. The target must disclose such information promptly, unless a delay is permitted to protect legitimate interests (e.g., ongoing negotiations), subject to strict MAR conditions.
If a rumor leaks or unusual trading occurs, the FSMA may compel immediate disclosure. Typically, disclosure is made via a joint press release or FSMA notice once a binding agreement is signed, especially if it triggers a mandatory takeover offer.
Additionally, shareholding thresholds must be disclosed under Belgian transparency laws. An acquirer crossing 5%, 10%, 15%, etc. must notify both the company and the FSMA within 4 trading days; the company then publishes this within 3 days. If the acquirer fails to notify, the issuer must disclose the crossing once it becomes aware.
Upon acquiring control, the acquirer must declare its intentions, including whether it plans further acquisitions or governance changes. This is often included in the offer document or a separate statement.
In private deals, no public disclosure is required. However, if the target is regulated (e.g., financial institution), sector-specific rules may require notification to the relevant authority. Employee consultation rules may also apply under labor law, but these are not public disclosures.
In summary, public M&A entails strict disclosure rules to ensure market transparency. Private transactions remain confidential unless specific sectoral obligations apply.
Under Belgian law, acquiring control of a listed company (i.e. surpassing 30% of voting rights) triggers a mandatory tender offer (MTO) for all remaining voting shares. The acquirer must notify the FSMA within two business days, and launch an offer in accordance with the Royal Decree on Takeover Bids.
The offer price must be at least equal to the highest price paid in the 12 months preceding the bid or the 30-day average market price prior to the triggering event, whichever is higher. If cash was paid for shares during that period, a cash alternative must be offered.
The offer document (prospectus) is submitted to the FSMA for pre-approval. Once approved, the offer is published and remains open for 2 to 4 weeks. The offer must be unconditional, except for regulatory approvals. After the acceptance period, the results are disclosed.
If the bidder reaches 95% or more of voting rights, it may launch a squeeze-out to acquire the remaining shares at the same price. If not, minority shareholders remain, as Belgian law does not grant a sell-out right at lower thresholds.
During the offer, the bidder cannot acquire shares outside the process, and the target’s board must remain neutral, refraining from defensive measures unless approved by shareholders.
In private companies, no MTO is required. Control may change hands freely unless restricted by contractual rights (e.g. tag-along). Minority shareholders are only protected through negotiated agreements or general corporate law.
In summary, the MTO framework ensures equal treatment and exit rights for minority shareholders in public companies, contrasting sharply with private transactions where such protections are absent
The three main structures for M&A in Belgium are share deals, asset deals, and statutory mergers.
In practice, share deals dominate due to simplicity and tax benefits; asset deals are used where selectivity or liability isolation is key; mergers are strategic tools; and SPACs are emerging but not yet established in the Belgian market.
Belgian M&A transactions commonly use two pricing models: the closing accounts (true-up) method and the locked-box mechanism.
In sum, Belgian deal practice mirrors international trends: true-ups for accuracy, locked-boxes for certainty, and earn-outs for bridging valuation gaps all enforceable under Belgian law through clear contract drafting.
Regulatory approvals are common conditions precedent in Belgian M&A. The main one is merger control: clearance from the Belgian Competition Authority is required if the parties’ combined Belgian turnover exceeds €100 million and at least two parties each exceed €40 million. For larger deals, EU clearance may be needed instead.
Sector-specific approvals also apply when the target operates in regulated industries (e.g. banking, insurance, energy, telecom). Acquiring control in these sectors often requires prior approval from relevant authorities like the FSMA or National Bank of Belgium.
Since 1 July 2023, Belgium has implemented a foreign direct investment (FDI) screening regime. Non-EU investors acquiring 25% (or even 10% in sensitive sectors like defence/cybersecurity) must notify the Interfederal Screening Commission. Approval (or lapse of review) is a CP, and non-compliance can lead to heavy fines.
Other CPs may include consents for government contracts, license transfers, or change-of-control clauses in key agreements. While employee consultation is not usually a formal CP, labor law may require prior consultation (notably in asset deals), and such processes are often built into the timeline.
In summary, Belgian M&A deals typically include CPs for competition clearance, regulatory consents, FDI screening (for non-EU buyers), and other approvals necessary for legal closing. These cannot be waived unilaterally and must be obtained before completion.
Belgian SPAs often include Material Adverse Change (MAC) clauses, especially when signing and closing are separated. A MAC clause allows the buyer to walk away if a major adverse event affects the target between signing and closing. These clauses usually define what constitutes a MAC (e.g. serious deterioration in financial condition) and exclude general economic downturns, pandemics, or industry-wide events. Belgian law has no statutory MAC concept, so enforceability depends on clear drafting and good faith ; buyers cannot invoke minor issues as pretexts. In public deals, any MAC condition must be pre-cleared by the FSMA and must be objective and severe.
Break-up fees (termination fees) are less common but may appear in auction or competitive situations. These are agreed sums paid if one party backs out (e.g. buyer loses financing or seller accepts another offer). Under Belgian law, excessive break-up fees may be reduced or voided as disproportionate penalties, especially if they serve to compel performance. In public M&A, break-up fees must respect board fiduciary duties and not deter better offers; they are typically modest (≤1% of deal value).
Other deal protections include non-compete and non-solicitation covenants, as well as exclusivity agreements (often signed with the LOI). These are usually covenants rather than conditions to closing, though a serious pre-closing breach may justify deal termination akin to a MAC.
Finally, SPAs usually include a bring-down condition requiring representations and warranties to remain true at closing. A financing-out (deal conditional on buyer securing funding) is generally disallowed in Belgian private and public deals.
In short, Belgian M&A practice uses MAC clauses and occasionally break-up fees to manage interim risk, but within the limits of reasonableness and good faith under civil law.
In Belgian M&A practice, representations and warranties (R&W) often include knowledge and materiality qualifiers to allocate risk and limit liability.
Knowledge qualifiers define the scope of what the seller is deemed to know. Since Belgian law does not provide a statutory definition, “Seller’s Knowledge” is typically contractually defined as the actual knowledge of specific individuals (e.g. directors or key managers), often “without obligation of inquiry.” Buyers may seek to include constructive knowledge (what the seller should have known with reasonable diligence), while sellers push for narrow definitions. If disputed, the buyer bears the burden of proving the seller’s knowledge, and good faith remains a guiding principle. Fraud, however, cannot be contractually excluded.
Materiality qualifiers are used to avoid breaches for minor issues. Phrases like “in all material respects” or “no material adverse effect” limit liability to significant problems. Again, there’s no statutory threshold; definitions are contractual or left to judicial discretion. Parties often link materiality to de minimis and basket thresholds in the indemnity regime, or define “Material Adverse Effect” with financial thresholds. This avoids disputes over trivial inaccuracies.
In practice, qualifiers are heavily negotiated: buyers prefer minimal use of qualifiers or broader knowledge definitions; sellers insist on limiting their exposure to what they actually and materially know. The final balance reflects diligence outcomes and bargaining power. Belgian law allows flexibility, but clarity in drafting remains key to enforceability.
In Belgian M&A transactions, bring-down provisions are standard when closing occurs after signing. They require that the seller’s representations and warranties (R&Ws) remain true at closing, usually “in all material respects.” If a breach occurs between signing and closing, and the bring-down is framed as a condition precedent, the buyer may refuse to close.
To avoid excessive termination risks, Belgian SPAs often qualify the bring-down by requiring that any inaccuracy must result in a Material Adverse Effect (MAE) or breach a materiality threshold. This allows the buyer to walk only in case of significant changes, not minor deviations. In practice, the seller signs a bring-down certificate at closing, possibly with disclosed exceptions.
In public deals, bring-down clauses are less relevant, especially in mandatory bids where conditions are limited by law. In private agreements preceding a public offer, however, bring-down conditions may apply to the initial acquisition.
Where signing and closing are simultaneous, the bring-down is moot. But where there is a gap (e.g., pending regulatory approvals), bring-downs serve as essential protections. Even if not a condition, a breach at closing may still trigger post-closing indemnification. Belgian practitioners generally treat bring-downs as standard closing conditions, alongside regulatory clearances.
Belgian law does not specifically regulate sandbagging (where a buyer closes a deal knowing a warranty is false, but still claims indemnification later). In practice, the issue is governed by general principles of contract law, notably the duty of good faith.
In Belgian M&A practice, various guarantee mechanisms are used to secure (i) the buyer’s payment obligations and (ii) the seller’s indemnification obligations post-closing.
Warranty & Indemnity (W&I) Insurance is increasingly used in Belgium, particularly in private equity transactions. It allows the buyer to claim from an insurer rather than the seller. Sellers often negotiate a minimal residual liability (e.g. €1), while the insurer covers the rest. However, a retention amount (e.g. 0.5-1% of the price) often remains uncovered and may still be escrowed.
Public deals require “certain funds” under Belgian takeover rules: the bidder must show the FSMA that it has secured financing (usually via a bank confirmation), protecting shareholders against failed payment after tendering.
Guarantee terms are highly deal-specific, reflecting the relative bargaining power and risk appetite of the parties. In general, escrow arrangements remain the most common and balanced solution in Belgian practice, offering buyers ready recourse while preserving the seller’s share of the price unless claims arise.
Indemnification provisions are standard in Belgian SPAs and form a core part of the contractual risk allocation. The typical model is “your watch / my watch” ; the seller bears responsibility for pre-closing matters, while the buyer assumes post-closing risks.
Today, Belgian SPAs include detailed representations and warranties (R&Ws), with the seller agreeing to indemnify the buyer for any breach. This provides the buyer with a clear contractual remedy, often more effective than relying on general legal principles, which offer limited recourse after a share sale.
The indemnity commonly covers:
Belgian SPAs typically exclude the application of statutory hidden defect rules (former Article 1641 Civil Code), replacing them with the negotiated indemnity framework. This ensures predictability and limits exposure to unforeseen claims.
The claim process is contractually regulated: buyers must notify the seller of claims within specified timeframes, and sellers may be granted the right to control or participate in the defence of third-party claims.
Belgian SPAs incorporate a well-defined set of limitations to the seller’s indemnity obligations, in line with international M&A standards. These include:
In sum, indemnification limitations in Belgian SPAs are intended to strike a balance between protecting the buyer and ensuring that the seller’s liability is confined to known and material post-closing risks.
In Belgian M&A, the main liability risks typically addressed in SPAs relate to tax, employment, environmental, and regulatory matters ;often complemented by specific indemnities for known issues. Their materiality varies by sector and due diligence findings.
SPAs commonly provide that indemnities do not cover liabilities already reflected in the accounts or price adjustments. Recoveries from third parties (e.g., insurance) reduce the seller’s liability.
In sum, Belgian practice mirrors other mature M&A markets: SPAs clearly allocate pre-closing liabilities, with specific terms tailored to the nature and foreseeability of each risk.
Under Belgian law and the Rome I Regulation, parties are generally free to choose a foreign law to govern their M&A agreements, and to designate foreign courts or arbitration for dispute resolution. This choice is fully valid, including in transactions involving Belgian targets, provided it does not conflict with mandatory Belgian rules.
Where foreign law is chosen, certain mandatory provisions of Belgian law may still apply ;particularly for matters such as share transfers (e.g. registration in the shareholder register), real estate, or corporate procedures governed by Belgian company law. Thus, even when the SPA is under foreign law, local formalities often remain governed by Belgian rules.
If the SPA is governed by foreign law but disputes are submitted to Belgian courts, those courts will apply the foreign law ; but require proof of its content, typically via party-appointed experts. This can introduce procedural complexity. For this reason, parties opting for foreign law often also prefer arbitration or foreign courts.
Foreign court judgments are enforceable in Belgium, subject to recognition:
Similarly, foreign arbitral awards are enforceable in Belgium under the New York Convention, provided standard conditions (e.g. public order) are met.
In sum, the choice of foreign law and jurisdiction in Belgian M&A deals is both valid and commonly enforced, though certain local elements remain governed by Belgian law. Enforcement of foreign judgments or awards is generally available, subject to legal formalities.
In Belgian M&A, both court litigation and arbitration are viable options for dispute resolution, and the choice depends largely on the deal’s nature and the parties’ priorities.
Belgian courts offer a low-cost option with access to appeals and enforceability across the EU via the Brussels I bis Regulation. However, proceedings can be slow, particularly in complex commercial matters, and are subject to strict language rules (Dutch or French). Judges may lack M&A-specific expertise, and proceedings are public by default, potentially exposing sensitive business matters.
Arbitration, by contrast, offers confidentiality, procedural flexibility, and the ability to appoint M&A-experienced arbitrators. It is typically faster in reaching a final decision (no appeals) and more suited to cross-border enforcement under the New York Convention. These advantages make arbitration the preferred choice in larger or international transactions, especially under CEPANI or ICC rules. However, it comes with higher costs and limited grounds for challenging the award.
In practice, arbitration is increasingly chosen in private M&A involving international parties, while domestic or smaller-scale deals may opt for Belgian courts for reasons of cost and simplicity.
