AGM in Mexico: Your Post-Meeting Filing Checklist

Planning an AGM in Mexico? The rules sit in the Ley General de Sociedades Mercantiles (General Law of Commercial Companies, published in the Diario Oficial de la Federación on 4 August 1934), known as the LGSM, and they hold a few surprises for foreign-owned subsidiaries. This guide covers who can call the meeting, how it runs, what shareholders approve and which filings follow. It is written for legal, tax and compliance teams managing Mexican entities from abroad.

What is the deadline for an AGM in Mexico, and who can call it?

The Annual Ordinary General Shareholders’ Meeting must take place within four months of the financial year end. For a calendar-year company, that means the end of April.

Who sends the invitation? The administrator, the board of directors (Consejo de Administración) or the commissaries (comisarios, the statutory supervisors). Minority shareholders have a fallback if those bodies stay silent:

• Shareholders holding at least 33% of the share capital can petition in writing. If nobody convenes the meeting within 15 days, they can ask a court to do it.
• A single shareholder can make the same request when no meeting has taken place for two consecutive fiscal years, or when the meetings held skipped the mandatory annual items. The same 15-day window applies before a judge steps in.

How much notice does the meeting need?

The company must publish the call through the electronic system run by the Secretaría de Economía (Ministry of Economy). The bylaws can set the notice period. Without a bylaw provision, the default is 15 days before the meeting.

The notice must include the agenda, and the person issuing the call must sign it. Cut corners here and you risk the whole meeting: resolutions adopted in breach of these requirements are null, unless all shares were represented at the vote.

How should an AGM in Mexico be run?

Physical meetings remain the standard. Electronic meetings are possible too, but only if the bylaws expressly allow them. The format must support simultaneous communication and verification of attendance.

Can you skip the meeting and sign a written resolution instead? The LGSM does not expressly authorise that for the AGM, so plan on a proper meeting.

Quorum depends on the type of meeting:

• Ordinary meeting, first call: at least half of the share capital must be represented. Resolutions pass by a majority of the votes represented, unless the bylaws demand more.
• Ordinary meeting, second call: the assembly can decide whatever portion of capital attends, provided the notice rules are met.
• Extraordinary meeting, first call: at least three-fourths of the capital stock must attend. Resolutions need votes representing at least half of the share capital, unless the bylaws set stricter conditions.

Each share normally carries one vote. Shareholders can attend in person or by proxy, and a proxy can be anyone except an administrator or commissioner. The bylaws set the form of the proxy. Without a bylaw rule, a written mandate works. In practice, most companies use a signed form naming the proxy, the shares represented and the agenda items.

One more right deserves a mention. Shareholders representing at least 25% of the shares present can postpone the vote on any matter they feel under-informed about. The delay lasts three calendar days, needs no new notice and works only once per matter.

What do shareholders actually approve?

The ordinary agenda is fairly fixed. Shareholders review the administrators’ report, approve the financial statements and decide how to allocate profit. They also appoint or ratify administrators, board members and commissaries, and set their remuneration when the bylaws are silent.

Extraordinary meetings handle weightier matters, such as capital changes, mergers, transformation, early dissolution and bylaw amendments. Both the board and shareholders can propose extra items. Holders of 33% of the capital can even call a meeting to address them.

Once adopted, resolutions bind every shareholder, including absent or dissenting ones, subject to the legal remedy of opposition.

Dividends come last. The company must set aside at least 5% of each year’s net profit for a legal reserve, until that reserve reaches 20% of the capital stock. Only then can shareholders approve a distribution, and the minutes must record it. General corporate law requires no separate notice to local authorities, unless tax or securities rules apply.

Does an AGM in Mexico require audited accounts?

Not automatically. Listed companies must present audited statements with an independent auditors’ opinion. Private entities, such as an S.A. de C.V. or an S. de R.L., need an audit only when they cross certain thresholds or when their bylaws or shareholders require one.

For example, revenue above roughly MXN 100 million can trigger a special audit report known as the dictamen fiscal. Either way, the administrators prepare the statements and the shareholders adopt or amend them.

What paperwork should you keep after the meeting?

Minutes go into the corporate book for assemblies. The chairperson and the secretary sign them, together with the commissary where there is one. If recording them in the book is not possible, a notary public must formalise them.

Extraordinary meeting minutes go further. The notarised minutes must be registered with the Public Registry of Commerce (Registro Público de Comercio), which makes the resolutions enforceable against third parties. Handwritten and qualified electronic signatures both work for most AGM documents, although anything formalised before a notary needs handwritten signatures.

Keep the corporate books at the registered office in Mexico. The secretary looks after them, and appointing a Mexican resident to that role is generally advisable.

When do changes take effect? Internally, a resolution bites once the meeting meets quorum and voting rules and the minutes enter the books. Changes needing registration, such as bylaw amendments or mergers, reach third parties only after registration and any statutory notices.

Which filings follow the AGM?

The LGSM itself requires no filing of AGM minutes with the Commercial Registry for ordinary meetings. Foreign-invested companies face extra duties, though, under the Foreign Investment Law. They report to the National Registry of Foreign Investments (RNIE), managed by the Ministry of Economy.

• Annual Economic Report: required at roughly MXN 110,000,000 in total assets, liabilities or annual income. Names starting with A to J file in April. Names starting with K to Z, or a number or special character, file in May.
• Quarterly Update Notices: due within ten business days after quarter end when reportable changes occur. Examples include a new name, tax domicile or economic activity, or movements above MXN 20,000,000 in certain accounts.
• Tax authority notice: companies must tell the Tax Administration Service (SAT) about changes to their capital structure.

Both monetary thresholds are subject to periodic revision, so check the latest ministerial resolutions before each filing season.

How can you verify compliance, and what if you miss a filing?

Mexico has no centralised register where companies file accounts. Approved financial statements stay in the company’s books, so there is nothing public to check.

For corporate changes, the local Public Registry of Commerce can issue an extract confirming the update. For RNIE filings, the online portal confirms successful submission.

Penalties follow the same split. The LGSM sets no sanction for a late AGM. Even so, the practical fallout can sting: internal disputes, unapproved accounts and possible liability for administrators who breach their duties.

RNIE failures cost more. Fines run from 30 to 100 UMA (Units of Measurement and Update, adjusted annually by INEGI) per day of delay. Persistent non-compliance can lead to temporary suspension of the RNIE registration, which may restrict certain corporate or financial operations.
