A Share Purchase Agreement (SPA) is a legally binding contract between a seller (often referred to as the vendor) and a buyer (referred to as the purchaser) for the sale and purchase of shares in a company. It shows that both parties have mutually agreed to the transaction and its terms. The SPA is a critical document in corporate transactions, ensuring clarity, mitigating risks, and protecting the interests of both parties.

This guide provides an in-depth overview of SPAs, including their contents, drafting considerations, circumstances requiring an SPA, and modern trends shaping their structure. It is intended for informational purposes only and does not constitute legal advice.

What is a Share Purchase Agreement?

An SPA outlines the terms and conditions governing the transfer of shares from the seller to the buyer. It is commonly used in scenarios such as:

  • Acquisition of a business through the purchase of its shares.
  • Exit of a partner or shareholder from a company.
  • Investment transactions where new or existing shares are purchased.
  • Mergers and acquisitions (M&A) involve share transfers.

The SPA ensures that both parties understand their rights, obligations, and liabilities, reducing the risk of disputes. It is distinct from an Asset Purchase Agreement (APA), which involves the sale of specific assets rather than shares.

Contents of a Share Purchase Agreement

An SPA is a detailed document tailored to the specific transaction. Below is a comprehensive list of key components typically included in an SPA:

Identification of Parties

  • Names and addresses of the seller(s) and buyer(s).
  • If the parties are corporate entities, details of their incorporation and registered office.
  • Inclusion of guarantors or covenanters, if applicable, to ensure contractual commitment.

Recitals (Preamble)

  • Background and context of the transaction.
  • Relationships between the parties (e.g., shareholder, promoter, or third-party investor).
  • Objective of the transaction (e.g., full or partial sale of shares).

Definitions and Interpretations

  • Clear definitions of key terms (e.g., “shares,” “closing date,” “warranties”).
  • Interpretative clauses to avoid ambiguity in the agreement’s language.

Details of the Shares

  • Name of the company whose shares are being sold.
  • Type of shares (e.g., common, preferred, or convertible).
  • Number of shares being transferred.
  • Par value or nominal value of the shares.
  • Percentage of ownership represented by the shares.

Consideration and Payment Terms

Payment structure, which may include:

  • Total purchase price and currency.
  • Upfront payment (deposit at execution).
  • Closing payment (payable on the closing date).
  • Escrow arrangements to cover potential indemnities or breaches.
  • Deferred payments or earn-outs based on future performance.
  • Pricing formula (e.g., fixed price, valuation-based, or adjusted based on due diligence).
  • Details of any security (e.g., liens or charges) registered against the shares.
  • Conditions triggering payment tranches, if applicable.

Conditions Precedent (CPs)

  • Conditions that must be fulfilled before the transaction can proceed, such as:
  • Regulatory approvals (e.g., from competition authorities or sector-specific regulators).
  • Shareholder or board approvals.
  • Third-party consents (e.g., from lenders or key customers).
  • Completion of due diligence to the buyer’s satisfaction.
  • A clause allowing waiver of certain CPs for flexibility.

Closing Mechanism

  • Details of the closing process, including:
    • Date and place of closing.
    • Actions to be completed (e.g., transfer of share certificates, board resolutions).
    • Delivery of closing documents (e.g., share transfer forms, resignation letters of directors).
  • A closing memorandum outlining the sequence of events.

Conditions Subsequent

  • Rare but sometimes included for post-closing obligations, such as:
    • Obtaining residuary permits or approvals.
    • Filing of regulatory disclosures.
  • Protections for the buyer in case of breaches of conditions subsequent.

Representations and Warranties

  • Seller’s Representations and Warranties:
    • Ownership and title to the shares (free of encumbrances).
    • Accuracy of the company’s financial statements.
    • Compliance with laws and regulations.
    • No pending litigation or disputes.
    • Details of the company’s capital structure, directors, and liabilities.
    • ESG compliance (e.g., environmental permits, labor practices).
  • Buyer’s Representations and Warranties:
    • Authority to enter the transaction.
    • Availability of funds to pay the purchase price.
    • Corporate status, if the buyer is an entity.
  • Importance: False representations can lead to legal recourse or purchase price adjustments.

Covenants

  • Pre-closing covenants:
    • Seller’s obligation to manage the company in the ordinary course of business.
    • Restrictions on major decisions (e.g., issuing new shares, incurring debt).
  • Post-closing covenants:
    • Non-compete or non-solicitation clauses for the seller.
    • Support for transition (e.g., knowledge transfer).

Indemnification

  • Provisions for compensating losses due to breaches of warranties, misrepresentations, or unforeseen liabilities.
  • Key elements:
    • Scope of indemnifiable losses (e.g., direct, indirect, or consequential).
    • Caps and thresholds (e.g., minimum claim amount, maximum liability).
    • Time limits for raising claims.
    • Escrow or holdback arrangements to secure indemnification obligations.
  • Highly negotiated to balance risk between parties.

Confidentiality

  • Obligations to protect sensitive information exchanged during the transaction.
  • Duration of confidentiality (typically 18–24 months).
  • Exceptions (e.g., disclosures required by law).

    • Failure to satisfy conditions precedent by a specified date.
    • Material breach by either party.
    • Mutual agreement.
  • Consequences of termination (e.g., return of deposits, confidentiality obligations).

Force Majeure

  • Excuses performance delays due to unforeseen events (e.g., natural disasters, pandemics, or financial crises).
  • Modern SPAs may include clauses addressing market volatility or geopolitical risks.

Dispute Resolution

Mechanism for resolving disputes, such as:

  • Arbitration: Preferred for confidentiality and speed (e.g., under the Arbitration and Conciliation Act, 1996, in India for domestic parties).
  • Mediation: As a preliminary step.
  • Litigation: If arbitration is not agreed upon.
  • Details of arbitration (e.g., seat, venue, number of arbitrators, governing law).

Governing Law and Jurisdiction

  • Law governing the SPA (e.g., Indian law for domestic transactions).
  • Jurisdiction of courts (typically the city of the seller’s registered office).
  • Clauses addressing cross-border transactions (e.g., choice of international law).

Notices

  • Procedure for sending notices (e.g., registered post, email).
  • Designated addresses and contact persons.
  • Provisions for electronic notices, reflecting digital trends.

Miscellaneous Clauses

  • Entire Agreement: The SPA supersedes prior agreements or negotiations.
  • Assignment: Restrictions on transferring rights under the SPA.
  • Severability: Invalid clauses do not affect the rest of the agreement.
  • Amendments: Requirement for written consent to modify the SPA.
  • Relationship Clause: Clarifies that the parties are not partners or agents.

Schedules and Annexures

  • Supporting documents, such as:
  • List of shares being sold.
  • Financial statements or due diligence reports.
  • Copies of approvals or consents.
  • Escrow agreement or indemnification terms.

Circumstances Requiring a Share Purchase Agreement

An SPA is necessary whenever shares of a company are bought or sold. Common scenarios include:

  • Business Acquisitions
    • A buyer acquires a controlling or minority stake in a company by purchasing shares.
  • Partner/Shareholder Exit
    • A partner or shareholder leaves a business, and their shares are purchased by remaining partners or third parties (e.g., in a partnership or private company).
  • Private Equity or Venture Capital Investments
    • Investors acquire shares in startups or growing businesses in exchange for capital.
  • Management Buyouts (MBOs)
    • Management teams purchase shares to gain ownership of the company.
  • Family Business Succession
    • Shares are transferred to the next generation or sold to external parties.
  • Distressed Sales
    • Shareholders sell shares in financially troubled companies to recover value.
  • Cross-Border Transactions
    • Foreign investors purchase shares in a domestic company, requiring compliance with foreign exchange regulations (e.g., FEMA in India).
  • Employee Stock Ownership Plans (ESOPs)
    • Employees exercise options to purchase shares, often formalized through an SPA.

Drafting a Share Purchase Agreement: Key Considerations

Drafting an SPA requires careful attention to the transaction’s specifics, applicable laws, and the parties’ objectives. Below are essential considerations:

Customisation

  • There is no universal SPA template. Each agreement must be tailored to the transaction, industry, and jurisdiction.
  • For example, SPAs in tech startups may include clauses on intellectual property, while those in manufacturing may focus on environmental compliance.

Due Diligence

  • The buyer must conduct thorough due diligence to verify:
    • The company’s financial health.
    • Legal compliance (e.g., tax, labor, environmental laws).
    • Ownership and encumbrances on shares.
    • Potential liabilities (e.g., pending lawsuits).
  • Discrepancies between the letter of intent (LOI) and SPA terms must be resolved before signing.

Negotiation of Key Clauses

  • Warranties and Representations: Sellers aim to limit their scope, while buyers seek broad protections.
  • Indemnification: Caps, thresholds, and time limits are heavily negotiated.
  • Payment Terms: Buyers may prefer deferred payments or earn-outs, while sellers seek upfront cash.
  • Non-Compete Clauses: Duration and geographic scope must be reasonable to be enforceable.

Regulatory Compliance

  • SPAs must comply with local and international laws, such as:
    • Companies Act, 2013 (India) for share transfers.
    • Foreign Exchange Management Act (FEMA) for cross-border deals.
    • Competition laws (e.g., approval from the Competition Commission of India).
    • Securities laws for listed companies (e.g., SEBI regulations in India).

Cross-Border Considerations

  • For international transactions, additional complexities arise:
    • Tax implications (e.g., withholding tax, double taxation treaties).
    • Currency exchange risks and hedging mechanisms.
    • Choice of governing law (e.g., English law for global deals).
    • Compliance with foreign investment regulations.

Digital and ESG Trends

  • Digital Transactions: SPAs increasingly include provisions for electronic signatures, virtual closings, and blockchain-based share transfers.
  • ESG Compliance: Buyers demand warranties on environmental impact, social responsibility, and governance practices.
  • Data Privacy: Clauses addressing compliance with data protection laws (e.g., GDPR, India’s DPDP Act) are critical for tech-driven companies.

Practical Tips for Drafting

  • Use clear, concise language to avoid ambiguity.
  • Include detailed schedules to support key clauses (e.g., list of liabilities).
  • Engage legal and financial advisors to ensure compliance and fairness.
  • Anticipate post-closing disputes by strengthening indemnification and dispute resolution clauses.

Modern Trends in Share Purchase Agreements

Technology Integration

  • Smart Contracts: Blockchain-based SPAs automate payment releases and share transfers.
  • E-Signatures: Widely accepted for remote execution, especially post-COVID.
  • Virtual Data Rooms: Used for secure due diligence and document sharing.

Sustainability Focus

  • Buyers prioritize ESG warranties to mitigate risks related to climate change, labor practices, and governance scandals.
  • Indemnities may cover ESG-related liabilities (e.g., environmental cleanup costs).

Geopolitical and Economic Volatility

  • Force majeure clauses now explicitly address trade sanctions, tariffs, and currency fluctuations.
  • Earn-out structures are popular in uncertain markets to tie payments to performance.

Cross-Border M&A Growth

  • Increased foreign investment in emerging markets like India requires SPAs to address FEMA compliance and tax structuring.
  • Multi-jurisdictional arbitration clauses are standard for dispute resolution.

Data-Driven Transactions

  • SPAs for tech companies include detailed warranties on data assets, cybersecurity, and AI intellectual property.
  • Due diligence now involves AI-powered analysis of financial and operational data.

Common Pitfalls and How to Avoid Them

Ambiguous Terms

  • Use precise definitions and avoid vague language.
  • Example: Clearly define “material adverse change” to avoid disputes.

Inadequate Due Diligence

  • Buyers should verify all warranties (e.g., financials, compliance).
  • Sellers should disclose potential liabilities to limit indemnification risks.

Overlooking Tax Implications

  • Structure payments to minimize tax liabilities (e.g., capital gains tax).
  • Consult tax advisors for cross-border deals.

Weak Indemnification Clauses

  • Ensure caps and thresholds are reasonable.
  • Use escrow to secure indemnification obligations.

Ignoring Post-Closing Obligations

  • Clearly outline transition support, non-compete terms, and residuary filings.
  • Include penalties for non-compliance.

Legal and Professional Support

Drafting an SPA is complex and requires expertise in corporate law, tax, and industry-specific regulations. Parties should engage:

  • Corporate Lawyers: To draft and negotiate the SPA.
  • Chartered Accountants: For financial due diligence and tax structuring.
  • Industry Experts: For sector-specific insights (e.g., tech, healthcare).
  • ESG Consultants: To assess sustainability risks.

In India, compliance with the Companies Act, 2013, SEBI regulations (for listed companies), and FEMA (for cross-border deals) is critical. For international transactions, legal advisors familiar with the governing law (e.g., English law, Delaware law) are essential.

Conclusion

A Share Purchase Agreement is a cornerstone of corporate transactions, ensuring clarity, fairness, and legal compliance in the sale and purchase of shares. By addressing key components such as consideration, warranties, indemnification, and modern trends like ESG and digital execution parties can mitigate risks and achieve their objectives.

Given the complexity and variability of SPAs, professional advice is crucial. Whether you’re a seller exiting a business or a buyer acquiring a stake, a well-drafted SPA is your safeguard against disputes and unforeseen liabilities.
