Shareholders Agreement in Mexico: Template, Key Clauses and Local Law (2026)

Are shareholders agreements valid in Mexico? Yes. A shareholders agreement (convenio entre accionistas) is valid in Mexico, and the law has become more accommodating over time. Two statutes set the frame: - The General Law of Commercial Companies (Ley General de Sociedades Mercantiles, LGSM), which governs the ordinary stock corporation (sociedad anonima, SA). A 2014 reform expressly recognised certain shareholder arrangements for the SA, including agreements among shareholders about buying and selling shares and about transfer restrictions.

• The Securities Market Law (Ley del Mercado de Valores, LMV), which governs the investment-promotion corporation (sociedad anonima promotora de inversion, SAPI). The SAPI was designed for investors and allows more flexible shareholder arrangements, such as drag-along, tag-along, vetoes and restrictions, with clearer statutory backing. For venture and private-equity deals in Mexico, the SAPI is the common vehicle precisely because the LMV gives shareholder arrangements firmer footing than the plain SA does. ## SA or SAPI: pick the vehicle that fits The type of company shapes what the agreement can safely do. - In an ordinary SA, some investor protections (such as broad vetoes or enhanced minority rights) are harder to embed and may need careful structuring. The LGSM, as reformed, recognises agreements about share transfers and purchase or sale options among shareholders.
• In a SAPI, the LMV expressly allows a wider menu: transfer restrictions, call and put options, drag-along and tag-along, special majorities, separate economic and voting rights, and limits on the general meeting's powers. Deciding SA or SAPI early avoids drafting rights into an agreement that the company form will not support. ## What belongs in the agreement, and what must sit elsewhere Some matters bind best inside the company's bylaws (estatutos sociales) rather than only in a private agreement, because bylaws are opposable to the company and, once registered, to third parties. A common pattern is to put structural rights (transfer restrictions, board composition, special majorities) into the bylaws and keep commercial and confidential terms in the shareholders agreement. Coordinating the two so they do not conflict is a core drafting task. ## Key clauses in a Mexican shareholders agreement ### Parties, company and purpose Identify the shareholders, the company (SA or SAPI), and the agreement's objectives. ### Governance and the board Set board size, nomination rights, quorum, and which decisions need a special majority or a shareholder veto. In a SAPI these can be reinforced in the bylaws under the LMV. ### Reserved matters List the decisions that require enhanced approval (new share issues, debt above a threshold, related-party deals, changing the business, selling key assets). ### Share transfers Cover transfer restrictions, rights of first refusal or first offer, permitted transfers, and lock-ups. The LGSM recognises transfer-restriction and purchase-or-sale arrangements among SA shareholders; the LMV gives SAPIs broader scope. ### Drag-along and tag-along Define drag-along (majority can compel a sale) and tag-along (minority can join a sale) mechanics, thresholds and price terms. These sit most comfortably in a SAPI. ### New funding and anti-dilution Address pre-emption rights on new issues, how new rounds are approved, and any anti-dilution protection. ### Information rights and reporting Set what financial and management information shareholders receive and how often. ### Deadlock and exit Provide a deadlock mechanism (escalation, buy-sell or shoot-out), and exit routes (sale, buy-back, listing), with valuation methods. ### Restrictive covenants and confidentiality Agree non-compete and non-solicit terms within competition-law limits, and confidentiality that survives exit. ### Governing law and disputes Mexican parties may choose law and forum. Arbitration is common and Mexico is a party to the New York Convention. Make sure the agreement and the bylaws point to a consistent dispute-resolution mechanism. ## A clause-by-clause skeleton 1.

• Leaving the agreement and the bylaws inconsistent, so a right in the agreement is not opposable to the company.
• Ignoring that structural protections often need to be in the registered bylaws to bind third parties.
• Overlooking competition-law limits on restrictive covenants.
• Not agreeing a clear valuation method for exit or buy-sell events. ## Managing the agreement after it is signed A shareholders agreement is a living document. Reserved-matter thresholds get tested at every board meeting, transfer and pre-emption clauses trigger on each financing, and the agreement has to stay in step with the bylaws as both are amended. Many teams keep the agreement, the bylaws and the cap-table documents in one AI contract workspace: the current versions together, per-clause risk flags, plain-English edits, and a live timeline of who approved what and when.
