A shareholders’ agreement is one of the most critical legal documents for any corporation, particularly for those with multiple founders, investors, or partners. It is a private, legally binding contract between a corporation’s shareholders that establishes their rights, responsibilities, and obligations. While the articles of incorporation create the legal entity and its share structure, the shareholders’ agreement provides the practical rules for governance, decision-making, and dispute resolution.
Clarify Governance: Clearly define how major decisions are made, who has voting rights, and what requires unanimous approval.
Protect Investments: Establish rules for share transfers, dividend distribution, and the protection of minority shareholders.
Prevent Disputes: Provide clear mechanisms for resolving disagreements, avoiding costly and time-consuming litigation.
Safeguard the Future: Include provisions for future growth, new investors, or the departure of a founder, ensuring the business can evolve smoothly.
As Pierre Marquis, Senior Legal Counsel at BDC, notes, “A shareholders’ agreement is the first step toward proper corporate governance and ensures all shareholders understand their rights and obligations.”
The specifics of a shareholders’ agreement will vary, but most comprehensive documents cover the following key areas:
A Unanimous Shareholders’ Agreement (USA) is a special type of shareholders’ agreement signed by all shareholders. Its unique feature is that it can transfer certain powers from the board of directors to the shareholders. This allows shareholders to have more direct control over the company’s affairs.
A USA is particularly valuable in small or closely held corporations where investors want to have a direct say in key decisions. Unlike directors, who have a fiduciary duty to the corporation, shareholders can predetermine their voting behavior on certain matters through a USA, providing an extra layer of protection for their investment.
As Pierre Marquis explains, “The purpose of a USA is to transfer powers from directors to shareholders, particularly in situations where investors want assurances on how major decisions are made.”
Every corporation is required by law to issue at least one class of shares, typically common shares. Common shares carry three fundamental rights:
Corporations can also create additional share classes (e.g., Class A, B, or C shares) with different rights and privileges. For example, a corporation might issue preferred shares that give investors a liquidation preference, ensuring they are paid first in a sale or liquidation scenario.
The articles of incorporation define the specific rights and features of each share class, and this structure is an essential part of the business’s long-term strategy for raising capital, maintaining control, and rewarding investors.
A shareholders’ agreement is far more than a simple legal formality; it is a blueprint for corporate governance and shareholder collaboration. By clearly defining rights, obligations, and dispute resolution mechanisms, a well-drafted agreement:
Whether you are a startup founder, a growing business, or a potential investor, having a comprehensive shareholders’ agreement is a critical step toward ensuring that everyone’s interests are aligned and that the corporation operates smoothly.
