Buy a Company in Switzerland: Process & Legal Guide
Buying an existing Swiss company is often the faster, more commercially rational route into the Swiss market. You inherit an operational business — clients, contracts, permits, staff, and a track record. Formation of a new entity gives you a clean slate but zero traction on day one. For most buyers with a clear target sector and timeline, acquisition wins.
This guide covers every stage of a Swiss company acquisition: finding the target, structuring the letter of intent, running due diligence, negotiating and signing the share purchase agreement, financing the deal, and completing the Commercial Register formalities. Where relevant, we flag the legal provisions that matter and the points where Swiss law diverges from what buyers accustomed to UK or US deals might expect.
Why Buy Rather Than Form?
A newly incorporated Swiss AG or GmbH takes 5–10 business days to register. That is not the constraint. The constraint is everything that comes after: building a client base, obtaining regulated licences (FINMA authorisation can take 12–18 months), establishing supplier relationships, and hiring staff in a tight labour market. An acquisition collapses that timeline. You step in as the new owner of an entity that already has those assets.
The trade-off is that you also step into whatever liabilities the target carries — disclosed and, without proper due diligence, undisclosed. Structuring the deal correctly is how you manage that.
For a broader look at corporate structuring options, see our guide to company formation in Switzerland.
Finding a Swiss Company to Buy
The Swiss SME market is large and relatively illiquid. Most deals happen off-market. Channels worth working:
- M&A advisors and business brokers. Firms specialising in Swiss mid-market transactions maintain proprietary deal flow. Fees are typically a retainer plus a success fee of 3–5% of enterprise value, sometimes structured on a Lehman scale.
- SHAB (Swiss Official Gazette of Commerce). The Schweizerisches Handelsamtsblatt publishes insolvency notices, composition proceedings, and liquidation orders. Distressed acquisitions from administrators or liquidators follow a different process but can offer value.
- Direct approach. Identifying a target and approaching the owner directly — a proprietary deal — is standard practice. A confidential approach letter or NDA-protected introductory call is the starting point.
- Cantonal chambers of commerce. Several cantonal chambers maintain business succession databases, particularly relevant for family-owned SMEs where the owner is approaching retirement with no internal successor.
- Industry networks and trade associations. For sector-specific acquisitions, trade bodies often know which businesses are quietly in play.
If speed of market entry is the priority, a shelf company in Switzerland — a dormant, already-registered entity — offers an alternative to a full acquisition process and can be operational within days.
Letter of Intent and Term Sheet
Once you have identified a target and had substantive commercial discussions, the next formal step is a Letter of Intent (LOI) — sometimes called a term sheet or Heads of Terms.
An LOI is typically non-binding on the main commercial terms but binding on specific procedural provisions. It covers:
- Indicative purchase price or valuation methodology — e.g., 6× trailing EBITDA, subject to adjustment.
- Transaction structure — share deal (buyer acquires the company’s shares) vs asset deal (buyer acquires specific assets and liabilities). The choice has significant tax consequences for both sides and is one of the first structural decisions to settle.
- Exclusivity period — buyers standardly request 30–60 days of exclusivity to complete due diligence before the seller can market the business to other parties. Sellers in competitive processes may resist or shorten this.
- Confidentiality — the NDA obligation is usually binding regardless of whether the deal proceeds.
- Break fee — less common in Swiss SME deals but seen in larger transactions where one party wants to deter the other from walking.
The LOI is not a sale and purchase agreement. Signing it does not commit either party to transact. But the exclusivity and confidentiality provisions are legally enforceable, and Swiss courts will hold parties to good-faith negotiation obligations (culpa in contrahendo) once a deal is sufficiently advanced.
Due Diligence
Due diligence is the investigative phase conducted during exclusivity. Its purpose is to verify the assumptions behind your indicative price, identify risks that need pricing or contractual protection, and surface any deal-breakers.
A standard Swiss acquisition due diligence covers:
- Legal: corporate structure, share register, material contracts, change-of-control clauses, litigation.
- Financial: audited accounts, management accounts, working capital analysis, debt and debt-like items.
- Tax: corporate tax compliance, VAT, withholding tax on historical dividends, any open tax audits.
- Regulatory: licences, permits, FINMA status (if applicable), sector-specific compliance.
- IP: ownership of trade marks, patents, domain names, software — particularly whether IP sits in the target or in a related entity.
- Employment: employment contracts, collective agreements, pension obligations (BVG/LPP), pending dismissals. Under Article 333 CO, employment contracts transfer automatically to the acquirer in an asset deal or business transfer; employees have a right to object.
The due diligence findings directly shape the representations and warranties requested in the SPA and any specific indemnities. See our detailed guide on due diligence in Switzerland for a full walkthrough.
The Share Purchase Agreement
The SPA is the central transaction document. In Swiss law, share transfers for an AG are effected by endorsement of the share certificate and entry in the share ledger — there is no public registration requirement for the transfer itself. For a GmbH, the quota transfer must be notarised and filed with the Commercial Register. Both structures are covered under the Swiss Code of Obligations (CO).
Key SPA provisions:
Purchase Price Mechanics
Three main approaches:
- Locked-box — price is fixed by reference to a historical balance sheet; economic risk passes to the buyer from the locked-box date. Cleaner and faster to close; favoured by sellers.
- Closing accounts adjustment — price is adjusted after closing based on actual net working capital, net debt, and cash at completion. More buyer-friendly but generates post-closing disputes if not tightly defined.
- Earn-out — part of the price is contingent on post-acquisition financial performance. Used where seller and buyer cannot agree on value, often in growth businesses. Creates ongoing relationship tension and requires robust earn-out mechanics to avoid disputes.
Representations and Warranties
Warranties are the seller’s factual statements about the business — financial statements are accurate, there is no undisclosed litigation, the target owns its IP, employment contracts are in order, and so on. They are the primary risk allocation mechanism. A breach entitles the buyer to claim damages.
Standard limitation periods in Swiss M&A:
- General business warranties: 2 years from closing.
- Title to shares: 10 years (Swiss statute of limitations; parties sometimes negotiate shorter).
- Tax warranties: 5–7 years (aligned with Swiss tax assessment limitation periods).
- Environmental warranties: 5–7 years.
Warranty & Indemnity Insurance
W&I insurance has become standard in Swiss M&A transactions above approximately CHF 5 million in deal value. The buyer takes out a policy that covers losses from warranty breaches, removing or limiting the buyer’s recourse against the seller. This facilitates clean exits for sellers (particularly PE-backed sellers), reduces escrow requirements, and gives buyers a solvent counterparty (the insurer) for claims. Premiums typically run at 0.9–1.5% of the insured limit.
Specific Indemnities
Where due diligence identifies a known, quantifiable risk — a pending tax audit, an environmental liability, a disputed customer claim — the parties negotiate a specific indemnity rather than relying on warranty coverage. Indemnities are typically euro-for-euro recoveries with longer limitation periods than general warranties.
Non-Compete
Swiss courts apply Article 340 CO to non-compete covenants. For an acquisition, seller non-competes of 2–3 years in the same geographic market and business area are standard and generally enforceable if the scope is proportionate. Overly broad restrictions risk being reduced or voided by Swiss courts.
Financing the Acquisition
- Cash. Simplest to execute; no third-party approval required; eliminates financing conditionality from the deal.
- Acquisition finance. Swiss banks — UBS, ZKB, Raiffeisen, major private banks — lend against acquisition targets. Leverage ratios for solid, cash-generative businesses typically run at 3–5× EBITDA; higher leverage is available in leveraged buyout structures, often through direct lending funds. Expect detailed information memoranda, management presentations, and legal due diligence as conditions of credit approval.
- Vendor loan. The seller finances part of the purchase price by extending credit to the buyer, repayable over an agreed term. Common in SME transactions where the buyer’s equity is insufficient to cover the full price and bank lending is constrained. Vendor loans are typically subordinated to senior bank debt.
- Private equity. For transactions above CHF 10–20 million, PE sponsors and family offices provide equity financing and frequently act as co-investors or lead acquirers. Swiss mid-market PE is active, particularly in industrial, healthcare, and business services sectors.
Closing Conditions and Commercial Register Filings
Most Swiss acquisitions include closing conditions that must be satisfied before the transaction completes:
- Regulatory approvals. FINMA pre-approval is required for acquisitions of qualifying participations in banks, insurance companies, and other regulated entities. The Swiss Competition Commission (WEKO/ComCo) merger control applies where combined turnover thresholds are met: CHF 2 billion worldwide and CHF 100 million in Switzerland. Below these thresholds, no ComCo filing is required. Details on the applicable notification procedure are published by WEKO (weko.admin.ch).
- Third-party consents. Change-of-control clauses in material contracts — key customer agreements, property leases, financing documents — may require counterparty consent before closing. These are identified in legal due diligence and managed during the pre-closing period.
- Board resignations and new appointments. Outgoing directors resign; new directors are appointed by shareholder resolution at closing. For an AG, director changes must be filed with the Commercial Register of the relevant canton.
Commercial Register mechanics:
- AG: Share transfers are not registered in the Commercial Register. Legal title passes when the buyer is entered in the company’s share ledger. Director changes are public filings.
- GmbH: Quota transfers require a publicly notarised deed and Commercial Register update. The new owner appears by name in the register.
The merger of Swiss entities — where the target is absorbed into the acquirer rather than continuing as a standalone — is governed by the Swiss Merger Act (Fusionsgesetz, SR 221.301), which sets out the procedural requirements for mergers, demergers, and conversions.
Post-Acquisition Steps
Completion is not the end of the process. Immediate post-closing items include:
- Shareholder resolution on dividend policy and any distributions.
- Notification to AHV, pension fund (BVG), and relevant insurers of change of ownership.
- Review and update of employment contracts and HR documentation.
- Integration planning — systems, brand, reporting lines.
- Notification to key customers and suppliers where commercially appropriate.

Foreign Buyers: Lex Friedrich and Lex Koller
Switzerland’s Lex Koller legislation (officially the Bundesgesetz über den Erwerb von Grundstücken durch Personen im Ausland, BewG) restricts acquisition of Swiss residential real estate by foreign persons. For the acquisition of a commercial or industrial operating company, Lex Koller does not apply. Foreign buyers can freely acquire Swiss AG or GmbH shares in commercial businesses without restriction.
The issue arises when the target company holds Swiss residential property — for example, a property developer or a company with staff accommodation. In that scenario, a Lex Koller analysis is required before signing. Lex Friedrich, the predecessor regime, shaped the current rules; the term is still used colloquially in practice.
See our mergers and acquisitions Switzerland overview for cross-border structuring considerations.
Stamp Duty on Share Transfers
Switzerland levies a securities transfer tax (Umsatzabgabe) on the transfer of taxable securities where a Swiss securities dealer acts as counterparty or intermediary. The rate is 0.15% for Swiss securities and 0.30% for foreign securities, calculated on the consideration paid. In many private M&A transactions neither party qualifies as a securities dealer, so no stamp duty arises on the transfer itself. This is a point to verify with Swiss tax counsel at term sheet stage rather than at closing.

FAQ
How long does it take to buy a company in Switzerland?
A straightforward SME acquisition with no regulatory filings typically takes 3–5 months from signed LOI to closing. This covers the exclusivity and due diligence period (4–8 weeks), SPA negotiation (4–8 weeks), and the closing mechanics. Deals requiring FINMA or ComCo approval add 3–12 months depending on the process.
What is the difference between a share deal and an asset deal in Switzerland?
In a share deal, the buyer acquires the company’s shares and inherits all assets and liabilities, including historical tax liabilities. In an asset deal, the buyer selects which assets and liabilities to acquire, leaving unwanted liabilities behind. Asset deals offer more protection against unknown historical liabilities but are less tax-efficient for sellers and operationally more complex — contracts, licences, and regulatory approvals typically need to be retransferred individually.
What due diligence should I carry out before buying a Swiss company?
A standard Swiss acquisition due diligence covers: legal (corporate structure, share register, material contracts, change-of-control clauses, litigation), financial (audited accounts, working capital, net debt), tax (corporate tax, VAT, withholding tax, open audits), regulatory (licences, permits, FINMA status), IP (trade marks, patents, software ownership), and employment (contracts, BVG pension obligations, collective agreements). The findings directly shape the warranty and indemnity protections in the SPA. Our due diligence guide covers each workstream in detail.
Can a foreigner buy a Swiss company?
Yes. Foreign buyers can freely acquire shares in Swiss commercial operating companies (AG or GmbH) without restriction. Lex Koller restricts foreign acquisition of Swiss residential real estate, not commercial businesses. The restriction becomes relevant only if the target company itself holds Swiss residential property.
Does Swiss competition law (ComCo/WEKO) apply to my acquisition?
Swiss merger control under the Cartel Act applies only if the combined worldwide turnover of the parties exceeds CHF 2 billion and at least two of the parties each have turnover in Switzerland exceeding CHF 100 million. Most Swiss SME transactions fall well below these thresholds and require no ComCo notification. For larger deals, pre-notification discussions with WEKO are advisable.
Is stamp duty payable on a Swiss share transfer?
Switzerland levies a securities transfer tax (Umsatzabgabe) of 0.15% on Swiss securities and 0.30% on foreign securities where a Swiss securities dealer is involved. In most private M&A transactions neither party qualifies as a securities dealer, so no stamp duty arises on the share transfer. Confirm this with Swiss tax counsel at term sheet stage.
What happens to employees when I buy a Swiss company?
In a share deal, employment contracts continue automatically — the employer of record is the company, which simply has a new shareholder. In an asset deal or business transfer, Article 333 CO provides that employment contracts transfer to the acquirer by operation of law, but employees have the right to object within one month and may then terminate their contracts.
What are the tax implications of buying a Swiss company?
In a share deal, the buyer steps into the target’s historical tax position. Any undisclosed tax liabilities become the buyer’s problem — which is why tax due diligence and robust tax warranties (with 5–7 year limitation periods) are essential. In an asset deal, the buyer acquires specific assets at their agreed value, generally resetting the tax basis, but the seller faces higher tax on any gains. Transfer taxes on real property held by the target (Handänderungssteuer, cantonal) may also be triggered in certain restructurings.
How does an earn-out work in a Swiss acquisition?
An earn-out defers part of the purchase price, making it contingent on the target’s post-closing financial performance — typically EBITDA or revenue over 1–3 years. It bridges valuation gaps between buyer and seller. Swiss law does not prescribe a specific form; earn-out provisions are negotiated contractually in the SPA. Key drafting points are the earn-out metric definition, the accounting methodology, buyer conduct restrictions during the earn-out period, and dispute resolution mechanisms.
What Commercial Register changes are required after buying a Swiss company?
For an AG: the share transfer itself is not registered in the Commercial Register. The buyer is recorded in the company’s internal share ledger. Any director or signatory changes must be filed with the relevant cantonal register. For a GmbH: the quota transfer requires a publicly notarised deed, and the new owner’s name appears in the Commercial Register. Both types of filing are typically completed within 1–2 weeks of closing.
Do I need a Swiss lawyer to buy a Swiss company?
Swiss law governs the SPA, the share transfer, and the Commercial Register filings. For a GmbH acquisition, a Swiss notary is mandatory. Beyond the formalities, the complexity of warranty negotiations, tax structuring, and regulatory clearances makes experienced Swiss M&A counsel essential for any transaction of material size. Buyers who rely solely on foreign counsel or attempt to self-navigate Swiss corporate law routinely encounter delays and preventable liability exposure.
