Shareholder Agreement in Brazil: Essential Clauses

The shareholder agreement (acordo de sócios or acordo de quotistas) is the legal instrument that governs the relationship between a company’s partners beyond the articles of association. While the articles of association address the company’s formal and public aspects, the shareholder agreement regulates strategic matters like governance, voting rights, exit mechanisms, conflict resolution, and investment protection.

This guide details the essential clauses every shareholder agreement should contain, focusing on practices adopted in the Brazilian market.

Why Have a Shareholder Agreement?

Companies with multiple partners inevitably face situations requiring clear rules: disagreements over strategic direction, a partner’s desire to exit, new investor admission, a partner’s death or incapacity, or the need for equity dilution.

Without a shareholder agreement, these situations are resolved exclusively by the Civil Code, which often fails to provide adequate solutions for business realities. The shareholder agreement:

• Prevents conflicts: establishes rules before disputes arise
• Protects investments: ensures returns and exit mechanisms
• Establishes governance: defines how decisions are made
• Attracts investors: demonstrates organizational maturity
• Regulates entry and exit: provides clear transition mechanisms

Legal Nature of Shareholder Agreements

The shareholder agreement is a parasocial contract, executed between partners (all or some) to regulate rights and obligations beyond the articles of association.

Legal basis:

• Civil Code, art. 997 et seq. (limited liability company)
• Corporate Law (Law 6,404/76), art. 118 (shareholder agreement — applicable by analogy)
• Principle of private autonomy (art. 421 of the Civil Code)

Characteristics:

• Binds only signatory parties (unless noted at the registry)
• Cannot contradict the articles of association or the law
• Can be modified by party consensus
• Fixed or indefinite term

Essential Clauses

1. Voting Rights and Governance

The agreement must define how corporate decisions are made:

Deliberation quorum:

Matter	Suggested Quorum
Ordinary operations	Simple majority
Articles amendment	75% or unanimity
Admission of new partners	Unanimity
New share issuance	75%
Profit distribution	Simple majority
Material debt contracting	75%
Sale of material assets	Unanimity

Veto matters (protective clauses):

• Change of corporate purpose
• Capital increase or reduction
• Merger, spin-off, or incorporation
• Borrowing above a specified amount
• Related-party transactions
• Extraordinary profit distribution

2. Tag-Along Clause

Tag-along protects the minority partner by guaranteeing the right to sell their shares on the same terms and price offered to the majority partner:

Mechanics:

1. Majority partner receives a purchase offer from a third party
2. Majority notifies minority partners of the offer terms
3. Minority partners may exercise the right to sell their shares to the same buyer on the same terms
4. If the buyer does not accept acquiring minority shares, the majority sale does not proceed Learn more about our real estate law services.

Purpose: prevent the minority from being “locked in” with an unknown new controlling partner.

3. Drag-Along Clause

Drag-along compels the minority partner to sell their shares alongside the majority when the latter receives an offer for 100% of the company:

Mechanics:

1. Majority partner receives an offer for 100% of shares
2. Majority notifies minority partners
3. Minority partners are compelled to sell on the same terms
4. Sale occurs in full

Purpose: enable the majority to complete a full company sale without minority blocking.

Limitations: drag-along must guarantee the minority a fair price and proportional conditions. Abusive clauses can be judicially challenged.

4. Right of First Refusal

Guarantees existing partners the right to acquire shares before they are offered to third parties:

Mechanism:

1. Partner wishing to sell notifies others with price and terms
2. Other partners have a deadline (typically 30 to 60 days) to exercise preference
3. If not exercised, shares may be sold to a third party on the same terms
4. If only some partners exercise, shares are distributed proportionally

5. Right of First Offer

A variation of the right of first refusal:

1. Partner wishing to sell first offers to other partners
2. Other partners submit a price proposal
3. If the selling partner declines, they may offer to the market — but not below the price offered by the partners
4. Protects partners without blocking liquidity

6. Non-Compete Clause

Prevents partners from competing with the company:

During the partnership:

• Prohibition from engaging in directly or indirectly competing activities
• Prohibition from participating as partner, administrator, or consultant in a competitor
• Scope: national or international territory

After departure from the partnership:

• Restriction period: 1 to 5 years (jurisprudence accepts up to 5 years)
• Territory: geographically defined
• Scope: specific and well-delineated activities
• Compensation: advisable to include financial consideration Learn more about our immigration and visa services.

7. Deadlock Resolution Mechanisms

Deadlock occurs when partners cannot reach agreement on matters requiring unanimity or supermajority:

Resolution mechanisms:

• Mediation: attempt at agreement with a professional mediator
• Shotgun clause (buy or sell): one partner offers to buy the other’s shares at a self-determined price; the other partner may accept selling or buy the offeror’s shares at the same price
• Russian roulette: similar to shotgun, with mechanical variations
• Arbitration: decision by arbitral tribunal
• Dissolution trigger: persistent deadlock for a defined period authorizes company dissolution

8. Valuation Method

The agreement must define how shares will be valued for exits, purchases, or sales:

Common methods:

Method	Description	Indication
Discounted cash flow (DCF)	Projection of future flows to present value	Companies with recurring revenue
EBITDA multiples	Value = EBITDA x sector multiple	Mature and profitable companies
Book value	Net accounting equity	Asset-heavy companies
Market value	Stock price or latest round	Listed companies or recent fundraise
Fair market value	Independent expert valuation	Dispute resolution

Complementary clauses:

• Valuation frequency (annual, every 3 years)
• Who performs the valuation (independent auditor, appointed expert)
• Valuation cost (who pays)
• Illiquidity and minority discount

9. Vesting Clause

Widely used in startups, vesting conditions full share ownership on meeting time or performance milestones:

Typical structure:

• Total period: 4 years
• Cliff: 1 year (partner gets nothing if they leave before 12 months)
• Monthly vesting after cliff: 1/48 of shares per month (or 1/36 after cliff)
• Acceleration: in case of company sale or termination without cause

Purpose: align long-term incentives and protect against premature departure.

10. Exit Clauses

Must address voluntary and involuntary exit scenarios:

• Voluntary exit: right of first refusal exercise, valuation, payment timeline
• Partner death: heirs join or remaining partners acquire shares
• Incapacity: legal representative takes over or shares are acquired
• Divorce: spouse does not become partner; shares are valued and converted to monetary amount
• For cause: exit with value loss or at minimum book value
• Judicial exclusion: for serious fault (art. 1,085 of the Civil Code)

11. Profit Distribution

The agreement should regulate:

• Minimum profit distribution percentage
• Frequency (quarterly, semi-annual, annual)
• Reinvestment vs. distribution priority
• Pro rata based on participation or with investor preference

Shareholder Agreements for Startups

Startups have specific needs:

• Mandatory vesting: for founders and key employees
• Anti-dilution: investor protection against excessive dilution
• Liquidation preference: investor receives first in a liquidity event
• Board seats: board composition based on participation
• Information rights: access to financial and operational information
• ESOP (Employee Stock Option Plan): share reserve for employees

Common Shareholder Agreement Mistakes

1. Not having a shareholder agreement: the most serious and most common error
2. Generic clauses: without detailing specific mechanisms
3. Not providing for deadlock: conflicts without resolution mechanisms
4. Undefined valuation method: generates disputes at exit
5. Excessive non-compete: abusive clauses are judicially annulled
6. Not updating the agreement: company changes, agreement remains outdated
