Share Deal vs. Asset Deal: The Two Paths to Selling a GmbH

Selling a GmbH can fundamentally be done in two different ways, each with distinct legal, tax, and strategic implications:

Share Deal: Sale of Company Shares

In a Share Deal, the shares (company interests) in the GmbH are sold. The GmbH itself remains the legal entity and only changes ownership.

Advantages of a Share Deal:

• Existing contracts, permits, and licenses generally remain unaffected
• Simpler transfer process since only the company shares are transferred
• Often more tax advantageous for the seller (e.g., potential partial tax exemption)
• No need for separate transfer of individual assets

Disadvantages of a Share Deal:

• Buyer assumes all liabilities and risks of the GmbH
• Limited depreciation opportunities for the buyer
• Complex due diligence required to identify hidden risks
• Notarization is mandatory (§ 15 Abs. 3 GmbHG)

Asset Deal: Sale of Assets

In an Asset Deal, individual or all assets, contracts, and business operations of the GmbH are sold. The GmbH as a legal entity remains and only holds the proceeds from the sale afterward.

Advantages of an Asset Deal:

• Selective acquisition of assets without legacy liabilities
• Buyer can establish a new depreciation basis (step-up)
• Lower liability risk for unknown obligations
• Flexibility in choosing which assets to acquire

Disadvantages of an Asset Deal:

• More complex process due to individual asset transfers
• Consent requirements for contract assignments (e.g., suppliers, customers)
• Often higher tax burden for the seller (no partial tax exemption)
• Risk of double taxation (at company and shareholder level)

The Sales Process in Detail: 7 Steps to a Successful Sale

A structured sales process increases the likelihood of success and minimizes risks. The following seven steps guide you systematically through the sale of your GmbH:

1. Strategic Preparation (6–24 Months Before Planned Sale)

The foundation for a successful sale is laid well before the actual transaction:

• Optimizing company structures: Separation of operating and non-operating assets
• Cleaning up the balance sheet: Reducing excessive liabilities, selling non-operating assets
• Securing key resources: Documenting know-how, securing key customers and employees
• Improving key performance indicators: Focus on increasing EBIT/EBITDA and cash flow
• Reducing dependencies: Diversifying customer and supplier relationships

Expert Tip: Ideally, start preparation 2–3 years before the planned sale. This allows sufficient time to improve KPIs and implement structural optimizations.

2. Professional Business Valuation

A solid business valuation forms the basis for realistic price expectations and successful negotiations:

• Choosing the appropriate valuation method: Income approach, DCF method, or multiples method
• Considering industry-specific factors: Typical EBITDA multiples or revenue multiples
• Identifying value drivers: Unique selling points, market potential, customer base
• Including intangible assets: Brands, patents, know-how, customer relationships

Comparison of Valuation Approaches:

3. Preparation of Professional Sales Documents

High-quality sales documents are crucial for making a positive first impression on potential buyers:

• Information memorandum: Comprehensive presentation of the company including business model, market, competition, financials, and future prospects
• Teaser: Anonymized short summary for initial buyer approach
• Financial fact book: Detailed financial data from the past 3–5 years
• Business plan: Presentation of future development potentials
• Sales prospectus: Professional presentation of all sales-relevant information

Checklist for a Convincing Information Memorandum:

• Company history and milestones
• Detailed product/service portfolio
• Organizational structure and key personnel
• Market and competition analysis
• Business development over recent years
• Financial figures and forecasts
• Customer structure and references
• Unique selling points and competitive advantages
• Growth potential and future outlook

4. Identification of Potential Buyers

A systematic buyer search increases the chances of optimal sale conditions:

• Strategic investors: Companies from the same or related industries seeking synergies
• Financial investors: Private equity firms or family offices focused on returns
• Management Buy-In (MBI): External managers aiming to join management
• Management Buy-Out (MBO): Acquisition by existing management

Suitable Channels for Buyer Search:

• Direct approach to potential strategic buyers
• Specialized M&A advisors and their networks
• Online business marketplaces such as DUB or nexxt-change
• Industry events and networking meetings

5. Confidential Contact and Preliminary Negotiations

Initial discussions lay the foundation for successful negotiations:

• Non-Disclosure Agreement (NDA): Protection against misuse of sensitive company data
• Management presentation: Introduction of the company and sales motives
• Indicative offers: Initial non-binding price proposals from potential buyers
• Letter of Intent (LOI): Statement of intent outlining transaction key points

Key Components of a Letter of Intent:

• Preliminary purchase price and payment terms
• Scope of the transaction (Share Deal/Asset Deal)
• Timeline for due diligence and contract negotiations
• Exclusivity agreement for a defined period
• Confidentiality provisions
• Conditions for the transaction (e.g., financing, regulatory approvals)

6. Due Diligence and Contract Negotiations

The Due Diligence phase is the critical review before contract signing:

• Financial Due Diligence: Examination of financial and earnings situation
• Legal Due Diligence: Review of contracts, permits, legal disputes
• Tax Due Diligence: Analysis of tax risks and obligations
• Commercial Due Diligence: Assessment of market, competition, and business model
• Technical Due Diligence: Evaluation of technical equipment, IT systems, products

Simultaneously, detailed contract negotiations begin, defining all aspects of the purchase agreement.

7. Contract Signing and Closing

The final step involves the legal execution of the transaction:

• Notarization: Statutory formality for the GmbH share purchase agreement
• Purchase price payment: According to agreed payment terms
• Commercial register entry: Official documentation of ownership change
• Handover: Systematic transfer of operational control
• Post-merger integration: Incorporation into the buyer’s structures

Professional Business Valuation: Finding the Right Price

Determining a realistic company value is one of the biggest challenges in selling a GmbH. Overly high price expectations can deter buyers, while undervaluation leads to financial losses.

Common Valuation Methods for GmbHs

1. Income Approach

   • Values the company based on future earnings
   • Considers entrepreneurial risk via capitalization rate
   • Especially suitable for established GmbHs with stable earnings

2. Discounted Cash Flow (DCF) Method

   • Based on future free cash flows
   • Accounts for company risk via discount rate
   • Well-suited for growth-oriented companies

3. Multiples Method

   • Simple, practical method based on comparable benchmarks
   • Typical multiples: 3–8x EBITDA (industry-dependent)
   • Quick initial estimate of company value

4. Asset-Based Approach

   • Based on the company’s tangible assets
   • Considers fair values of fixed assets and inventories
   • Suitable for asset-intensive companies

Typical Multiples by Industry

Value Drivers and Value-Reducing Factors

Value Drivers Increasing Purchase Price:

• Stable, recurring revenues and cash flows
• High profitability above industry average
• Broad, diversified customer base without concentration risks
• Strong market position and unique selling points
• Low investment needs in coming years
• Established management independent of owner

Value-Reducing Factors:

• High dependency on owner/seller
• Strong customer concentration (>20% revenue from one customer)
• Declining margins and results
• Investment backlog and outdated equipment
• Unresolved succession in key positions
• Legal or regulatory risks

Costs and Taxes in Selling a GmbH: The Financial Dimension

Transaction Costs in Selling a GmbH

Selling a GmbH incurs significant transaction costs that should be considered in the overall calculation:

Total Cost Indication: For mid-sized transactions (purchase price €1–5 million), total costs typically amount to 5–10% of the sale price.

Tax Aspects of Selling a GmbH

The tax consequences of a GmbH sale depend heavily on the transaction structure and the seller’s personal circumstances:

Share Deal: Tax Treatment of Selling GmbH Shares

For individual sellers:

1. Ownership up to 1%:

   • Capital gains tax at 25% plus solidarity surcharge and possibly church tax
   • Tax advantageous for high capital gains

2. Ownership above 1% (substantial participation):

   • Partial income method: 60% of capital gain taxable, 40% tax-free
   • Tax rate: personal income tax rate on taxable portion
   • Tax beneficial for low to medium income tax brackets

3. Exemption under § 16 EStG:

   • Upon complete cessation of entrepreneurial activity
   • Up to €45,000 exemption (phases out above €136,000 capital gain)
   • One-time lifetime use

For corporate sellers:

• 95% of capital gain tax-exempt (§ 8b KStG)
• Effective tax rate approx. 1.5% on capital gain
• Especially advantageous for high capital gains

Asset Deal: Tax Treatment of Selling Assets

1. At the selling GmbH level:

   • Corporate income tax (15%) and trade tax (approx. 14–17% depending on local rate)
   • Taxation of hidden reserves on sale above book value
   • Overall tax burden approx. 30%

2. Upon distribution to shareholders:

   • Additional capital gains tax of 25% (plus solidarity surcharge, possibly church tax)
   • Partial income method possible for substantial shareholders
   • Total tax burden can exceed 45%

Tax Optimization Strategies in Selling a GmbH

Early tax planning can realize significant tax advantages:

1. Establishing a Holding Structure:

   • Formation of a holding GmbH before planned sale
   • Contribution of GmbH shares into holding (usually tax-neutral)
   • Sale of GmbH shares by holding (95% tax-exempt)
   • Beneficial with long-term planning (>7 years before sale)

2. Staggered Sale:

   • Spreading capital gains over several tax years
   • Utilizing progression advantages in income tax
   • Reducing overall tax burden

3. Reinvestment Reserve under § 6b EStG:

   • For asset deals and sale of certain assets
   • Deferral of hidden reserves by reinvestment
   • Tax deferral effect for up to 4 years

4. Optimizing Purchase Price Allocation:

   • In asset deals: allocation of purchase price to depreciable assets
   • Benefits for buyer can lead to higher purchase price
   • Win-win through tax-optimized structuring

Minimizing Liability Risks: Legal Protection for Sellers

Selling a GmbH involves significant liability risks that can be minimized through careful contract drafting.

Typical Liability Risks in Selling a GmbH

Share Deal:

• Liability for warranties regarding GmbH shares and company
• Liability for undisclosed liabilities and risks
• Tax liability for past periods
• Liability for incorrect guarantees and representations

Asset Deal:

• Liability for defects in sold assets
• Liability under § 25 HGB for business continuation
• Liability for employee claims under § 613a BGB
• Warranty liability for assured characteristics

Strategies to Minimize Liability

1. Careful Warranty Catalogs:

   • Clear definition and limitation of warranties given
   • Differentiation between representations and mere descriptions
   • Avoidance of “best knowledge” warranties without fault standard

2. Temporal Liability Limitation:

   • Shortening statutory limitation periods to 12–24 months
   • Different periods depending on warranty type (e.g., longer for tax warranties)
   • Clear provisions on suspension and interruption of limitation

3. Monetary Liability Caps:

   • Setting liability caps, typically 10–30% of purchase price
   • Introduction of deductibles (baskets) for minor damages
   • De-minimis rules for trivial claims

4. Special Protection Instruments:

   • Purchase price escrows for potential warranty claims
   • W&I insurance (Warranty & Indemnity Insurance)
   • Earn-out agreements for risk sharing between buyer and seller

M&A Insurance as a Modern Protection Tool

W&I insurance is gaining importance in GmbH sales:

• Function: Insurance covers liability for warranty breaches
• Costs: Typically 1–3% of insured amount
• Advantages: “Clean exit” for seller, greater security for buyer
• Limitations: Known risks and certain warranty types often excluded

The Optimal Buyer Search: Strategies to Identify the Ideal Buyer

A systematic search for the right buyer is crucial for a successful GmbH sale on optimal terms.

Buyer Types and Their Specific Characteristics

1. Strategic Investors:

   • Companies from the same or adjacent industries
   • Primary interest: synergies, market share, technologies
   • Advantages: higher willingness to pay due to synergies
   • Disadvantages: possible integration with layoffs, cultural changes

2. Financial Investors / Private Equity:

   • Focus on financial returns and medium-term exit (5–7 years)
   • Primary interest: value creation potential, stable cash flows
   • Advantages: professional transaction handling, capital for growth
   • Disadvantages: high return expectations, restructuring pressure
