What Is the Difference Between a Shareholders Agreement and a Joint Venture Agreement?

Summary

  • A shareholders’ agreement governs the internal relationships and rights of shareholders within an existing company, whilst a joint venture agreement is project-specific and outlines how separate parties will collaborate towards a defined goal.
  • These two agreements differ in scope, purpose, and structure, and choosing the wrong framework can leave businesses exposed to governance gaps or unclear liability.
  • Key distinctions include whether a new entity is created, the duration of the arrangement, and the nature of the parties’ relationship.
  • This article is a plain-English guide to shareholders’ agreements and joint venture agreements for UK business owners, directors, and investors.
  • The content has been produced by LegalVision, a commercial law firm that specialises in advising clients on corporate governance and commercial agreements.

Tips for Businesses

Choose your agreement based on your relationship’s nature and duration. Use a shareholders’ agreement for ongoing company governance and a joint venture agreement for project-based collaboration. Ensure each agreement clearly addresses contributions, decision-making, profit sharing, dispute resolution, and exit terms before commencing any business arrangement.

Two commonly encountered agreements in the UK are the shareholders’ agreement and the joint venture agreement.  Although they might seem similar initially, understanding their differences is crucial for business owners, investors, and legal practitioners.  This article explores the distinctions between these two types of agreements and their respective roles within a business framework. 

Shareholders Agreement: An Overview

A shareholders’ agreement is a contract between a company’s shareholders detailing their rights and obligations. It serves as a governance tool to ensure that shareholders agree regarding the company’s operation and management.

Key Aspects

Some helpful aspects covered in a shareholder agreement can include:

  1. Rights and Obligations: Clearly define the rights and responsibilities of shareholders, such as voting rights, dividend entitlements, and participation in management decisions;
  2. Management Structure: Outlines the management hierarchy, including the appointment and removal of directors and their specific roles and responsibilities;
  3. Share Transfer: Establishes the procedures and restrictions regarding the transfer of shares to maintain control and stability within the company;
  4. Dispute Resolution: Provides mechanisms for resolving disputes among shareholders, often through mediation or arbitration, to avoid costly litigation; and
  5. Exit Strategies: Details the procedures for shareholders exiting the company, including buy-sell provisions and valuation methods for shares.

Joint Venture Agreement: An Overview

A joint venture agreement, on the other hand, is a contract between two or more parties who agree to collaborate on a specific business project or venture.

Unlike a shareholder agreement, which pertains to an existing company, a joint venture agreement is project-specific. It can involve creating a new entity or outlining the terms of cooperation between the parties.

Key Aspects

Some helpful aspects covered in a joint venture agreement can include:

  1. Rights and Obligations: Clearly defines the purpose of the joint venture and the specific objectives that the parties aim to achieve;
  2. Management Structure: Details the contributions of each party, whether in terms of capital, resources, or expertise, and how these contributions will be valued;
  3. Share Transfer: Establishes the management structure of the joint venture, including decision-making processes and the appointment of key personnel;
  4. Dispute Resolution: Specifies how profits and losses will be distributed among the parties, which can vary depending on their contributions and the terms of the agreement; and
  5. Exit Strategies: Outlines the duration of the joint venture and the conditions under which it can be terminated or extended.

Key Differences Between Agreement Types

Scope and Purpose

A shareholders’ agreement primarily focuses on a company’s internal governance, ensuring the protection of shareholders’ interests and the company’s smooth operation.

In contrast, joint venture agreements centre around a specific project or business activity, outlining how parties will collaborate to achieve a common goal.

Parties Involved

A shareholders’ agreement involves the shareholders of a single company.  Whereas a joint venture agreement can involve multiple parties, including individuals, companies, or other entities, collaborating for a specific purpose.

Nature of the Relationship

A shareholders’ agreement concerns a company’s long-term governance and operation. However, a joint venture agreement is typically project-based, with a defined timeline and specific objectives.

Entity Creation

A shareholders’ agreement does not create a new entity but pertains to an existing company.  However, a joint venture agreement may involve the creation of a new entity or simply form a contractual relationship without creating a new entity at that point.

Flexibility and Specificity 

A shareholders’ agreement provides a framework for a company’s ongoing operation, offering flexibility to adapt to changing circumstances within the company.

In contrast, a joint venture agreement is highly specific to the project or venture, with detailed terms tailored to the parties’ objectives and contributions.

When Should You Use Each Agreement?

Choosing the right agreement depends on what you are trying to achieve.

If you are setting up a company with co-founders or bringing in investors, a shareholders’ agreement is the right tool. It protects everyone involved and sets clear rules for how the company runs.

If you are partnering with another business to deliver a specific project, such as a construction contract, a product launch, or a technology development, a joint venture agreement is more appropriate.

In some cases, you may need both. For example, if two companies form a new company to run a joint venture, they will likely need a joint venture agreement between the parent companies and a shareholders’ agreement for the new entity.

Getting the structure right from the start avoids disputes later. It also ensures each party’s contributions, rights, and exit options are clearly documented before work begins.

Key Statistics

  1. 87%: UK joint ventures that include a comprehensive shareholders’ agreement to govern decision-making and exit rights.
  2. 64%: Proportion of joint venture disputes that arise from poorly drafted or absent shareholders’ agreements.
  3. 42%: Increase in the use of detailed deadlock and exit provisions in shareholders’ agreements since 2023.

Example: Shareholders Agreement

A group of entrepreneurs starts a tech company, and to protect their interests, they draft a shareholders’ agreement.  The agreement outlines the roles of each founder, how decisions will be made, and the process for bringing in new investors.  

It also includes provisions for resolving disputes and handling the departure of any founder.  This ensures that the company can operate smoothly and that the founders’ interests are protected as the company grow.

Key Takeaways

While shareholder agreements and joint venture agreements may appear similar, they serve distinct purposes and involve different legal and practical considerations.  Understanding the differences between these agreements is crucial for UK businesses, as it enables them to choose the appropriate legal framework for their needs.  

By carefully drafting and regularly reviewing these agreements, businesses can protect their interests, foster successful collaborations, and confidently navigate the complexities of the business environment.

Frequently Asked Questions
