# What Is Stockholder Agreement?

> A stockholder agreement is a contract among shareholders that sets governance, transfer restrictions, board rights, and exit mechanics beyond what the charter alone covers.

A **stockholder agreement** binds shareholders to rules on transfers, information, and control that may not appear in the certificate of incorporation.

## How it works

Parties negotiate ROFR (right of first refusal), co-sale rights, board composition, non-compete clauses, and deadlock resolution. In venture-backed companies, many provisions live instead in **investors' rights**, **voting**, and **ROFR/co-sale** agreements—but early-stage startups and LLCs often use a unified stockholder agreement before institutional rounds.

Amendments usually need specified supermajorities; one holdout can block changes.

## Why it matters

- **Founders:** Read transfer restrictions before promising secondary liquidity to employees.
- **Investors:** The agreement enforces who can block a sale and what information rights you have pre-board seat.

## Common mistake

Assuming the charter is the only governing document. Side agreements often control day-to-day shareholder behavior.

## Related ideas

Shareholders agreement, ROFR, voting agreement, and investors' rights agreement.
## When you will see it

Early cofounder teams sign stockholder agreements before institutional money arrives, setting ROFR and transfer rules among founders.

## Questions to ask

- Does the agreement conflict with later investors' rights documents?
- Who can block a sale or secondary under ROFR?
- How are deadlocks resolved if cofounders disagree?
## Practical takeaway

Treat **stockholder agreement** as something to define precisely in writing—not assume everyone in the room shares the same meaning. In term sheets, board decks, and LP updates, tie the concept to a concrete decision: a vote, a price input, a fund policy, or a metric formula. When definitions drift, teams misprice risk, miss leverage, or waste cycles on the wrong conversation.

## FAQ

### What is stockholder agreement in simple terms?

A stockholder agreement is a contract among shareholders that sets governance, transfer restrictions, board rights, and exit mechanics beyond what the charter alone covers. It is a label you will hear in deal conversations, cap tables, and fund marketing—not abstract theory.

### Why does stockholder agreement matter?

Signed early, it shapes who can sell, vote, and block major decisions. Founders and investors both need a shared definition before term sheets, diligence, or exit talks get serious.
