Partial Business Sale: Selling a Minority Stake Without Losing Control (2026)

Short answer. A partial sale means selling a fraction of the share capital — typically 10% to 49% — while keeping operational leadership and legal control. Three levers combine: bylaws (voting rights, approval clauses), shareholders' agreement (pre-emption, tag-along) and tax structure (apport-cession, Pacte Dutreil). Done badly, the deal dilutes the founder's authority or triggers heavy tax. Done right, it secures cash, brings in a strategic partner and prepares the eventual exit.

A full sale answers an exit logic. A partial sale answers at least four different logics:

• Partial liquidity: turn part of the professional wealth into cash without giving up the rest.
• Strategic partner: bring in an industrial, a fund or a commercial partner.
• Owner Buy-Out (OBO): use a holding company and debt to buy back part of the shares.
• Progressive transmission: prepare a future full sale by phasing in a successor.

A well-built partial sale starts with objective clarification, not with picking a tax vehicle.

2.1. Corporate form#

In a SAS / SASU, the bylaws are highly flexible (French Commercial Code arts. L.227-13 et seq.). The most common form for a partial sale.

In a SARL, the regime is stricter: approval is essentially mandatory for transfers to non-shareholders (art. L.223-14).

In a SA, shares are in principle freely transferable; approval clauses must be in the bylaws.

2.2. Key statutory clauses#

• Approval clause (agrément): existing shareholders' consent required.
• Lock-up clause: prohibits transfer for a limited period.
• Pre-emption clause: priority on shares offered.
• Double-voting rights or preferred shares: sell in value while keeping voting power.

2.3. Shareholders' agreement#

The agreement complements the bylaws with non-erga omnes but binding clauses:

• tag-along right protecting minorities;
• drag-along right protecting the majority on a future full sale;
• good leaver / bad leaver applicable to the founder;
• non-compete, non-solicitation, lock-up;
• price adjustment and put/call mechanisms.

A well-drafted agreement is the main tool to preserve control.

3.1. Direct sale#

The simplest path: capital gains under the 30% flat tax (PFU) under CGI art. 200 A: 12.8% income tax + 17.2% social levies. Option for progressive bracket and certain holding-period allowances under CGI art. 150-0 D in some cases.

3.2. Contribution-and-sale (CGI art. 150-0 B ter)#

The founder contributes the shares to a controlled holding before the sale. The capital gain on the contribution benefits from a deferral of taxation subject to the conditions of CGI art. 150-0 B ter (notably reinvestment in eligible economic activities if the holding sells within a short period). Exact reinvestment percentages and qualifying assets are set by law and BOFiP doctrine, to be verified at transaction date with a chartered accountant and tax lawyer.

3.3. Pacte Dutreil (CGI art. 787 B)#

For family transfer or donation, Pacte Dutreil allows, under strict conditions, a partial exemption from gift or inheritance duties. May combine with a partial sale to third parties.

3.4. Owner Buy-Out (OBO)#

The founder creates a holding which raises debt to buy back part of the shares. The founder retrieves cash, retains majority via the holding, and the holding repays the debt with future dividends. Anti-abuse principles must be respected.

1. Independent valuation: DCF, comparable multiples, yield-based value.
2. Vendor due diligence before the buyer's due diligence.
3. Bylaws and agreement: redrafting before, never after.
4. Tax structuring: arbitrage between direct sale, apport-cession, OBO, Dutreil.
5. Stakeholder information: managers, employees (mandatory employee-information rules to anticipate), banks.
6. Post-deal plan: founder's role, possible earn-out, future exit conditions.

A successful partial sale rests on three balances.

• Legal balance: a well-built agreement allows selling 40% of capital while keeping 60% of effective control via voting rights, governance and blocking clauses.
• Tax balance: the 30% flat tax is simple; apport-cession is powerful but demanding.
• Psychological balance: a founder selling partially without clarifying their future role exposes themselves to friction.

The worst scenario is the "reflex" partial sale, triggered by an opportunity without a clear wealth project.

• Recharacterisation of apport-cession in case of non-compliant reinvestment.
• Tax abuse of law on poorly calibrated OBO structures.
• Loss of effective control: a minority investor with strong protection clauses can block major decisions.
• Imbalanced agreement: overly broad drag-along clauses may force an unwanted future sale.
• Post-OBO dividend tax: to anticipate in the repayment plan.

• Why sell partially? Liquidity, partner, transmission, wealth securing.
• What percentage? 10–25%, 25–49%, 51%+.
• Target valuation? Independent, documented, defensible.
• Tax structure? Arbitrage between liquidity and deferral.
• Which rights to keep? Voting, governance, protection clauses.
• What role afterwards?

• Apport-cession and reinvestment: BOFiP doctrine details modalities and scope. Verify at transaction date.
• Employee information rules in case of sale: calendar to integrate from day one.
• EU merger regulation: above certain thresholds.
• Tax due diligence: off-balance commitments and prior tax disputes scrutinised.
• CSRD / ESG: depending on size, sustainability reporting may influence valuation and due diligence.

1. Can I sell 30% of my company without losing control? Yes, if the bylaws and agreement are designed for it. Legal control rests with the holder of the majority of voting rights, which may differ from the share of capital depending on clauses.

2. Difference between apport-cession and direct sale? A direct sale triggers capital-gains taxation immediately (PFU 30% by default). Apport-cession via a controlled holding allows, under conditions, the deferral provided by CGI art. 150-0 B ter.

3. Is Pacte Dutreil compatible with a partial sale? Pacte Dutreil concerns gratuitous transfers. It can combine with a partial sale to third parties, but strict conditions of CGI art. 787 B must be observed for the gratuitous portion.

4. How long does a partial sale take? Typically six to eighteen months, depending on accounting maturity, agreement complexity, parties and due diligence.

5. Do we need separate counsel and chartered accountant? Yes. Counsel handles legal acts; the chartered accountant secures valuation, tax structuring and accounting due diligence.

A well-prepared partial sale typically runs over six to twelve months. The calendar matters because it conditions the founder's bandwidth and the credibility of the operation in front of buyers.

Months 1 to 2 — preparation. Independent valuation, vendor due diligence (financial, tax, social, legal), update of the bylaws, drafting or revision of the shareholders' agreement template. The chartered accountant produces a clean, audit-ready P&L, balance sheet and cash flow over three years, plus a five-year forecast.

Months 3 to 4 — outreach and short-list. Information memorandum, NDAs, first meetings. The founder assesses cultural and strategic fit, not only price. A clear go / no-go grid prevents the deal from drifting toward whoever signals fastest.

Months 5 to 6 — due diligence. Data room, expert interviews, Q&A management. Bandwidth pressure peaks at this stage; the chartered accountant typically handles 60% to 70% of incoming questions to protect operational management.

Months 7 to 9 — negotiation and SPA. Term sheet, share purchase agreement, representations and warranties, escrow, earn-out clauses if any. Bylaws and shareholders' agreement updated to reflect the new cap table and governance.

Months 10 to 12 — closing and integration. Signing, payment, governance set-up, communication to teams and customers. Post-deal monitoring of any earn-out clauses or working-capital adjustments.

A premature timeline (under six months) usually reveals an unprepared file. A timeline beyond twelve months drains the founder's energy and signals difficulty to the market. The chartered accountant's role is to keep the calendar realistic and the file constantly closing-ready.

A well-led partial sale preserves control, secures a portion of wealth and prepares the next step. It requires a clear objective, a robust agreement, an adapted tax structure and an explicit post-deal plan. The chartered accountant's role is to inform every arbitrage, from valuation to post-deal cash.
