What Is a Shareholders Agreement?
Last reviewed: June 2026
A shareholders agreement is a contract among the owners of a corporation that governs their relationship, rights and obligations, and how key decisions about the company will be made. It supplements the corporation's bylaws with more detailed private agreements among shareholders.
Every corporation with more than one shareholder should have one. Without it, the relationship among shareholders is governed entirely by corporate bylaws and state corporate law — which may not reflect what the shareholders actually agreed to when they went into business together.
What It Covers
Voting arrangements, share transfer restrictions with right of first refusal, buyout provisions for departing owners, drag-along and tag-along rights, anti-dilution protection, and board composition.
Frequently Asked Questions
What is the difference between a shareholders agreement and corporate bylaws?
Bylaws are the formal governing document filed with the state. A shareholders agreement is a private contract addressing the relationship among owners in more detail.
Do all shareholders need to sign?
Yes. It only binds those who sign. New shareholders should sign a joinder agreement making them parties.
Can it be amended?
Yes, typically by vote of all shareholders or a specified majority as defined in the agreement.
Is it the same as an operating agreement?
No. An operating agreement governs an LLC. A shareholders agreement governs a corporation.
What happens to these provisions if the company is acquired?
Acquisition provisions — particularly drag-along and tag-along rights — govern how shareholders participate in an acquisition. The agreement typically terminates upon a change of control.
