As private joint‑stock companies grow and expand, their original legal structure may no longer meet their financial and investment needs. In such situations, one of the most important legal solutions for expanding business activities is changing the company’s legal form.

Private joint‑stock companies are usually established with a limited number of shareholders and investors. However, as business activities expand—such as entering larger projects, requiring greater capital, or planning to access capital markets— it may become necessary to change the company’s structure and convert it into a public joint‑stock company.

In addition, only public joint‑stock companies are permitted to offer and trade their shares in the capital market. For this reason, many private joint‑stock companies seek to convert to a public structure in order to attract broader financial resources and new investors.

Iran’s Commercial Code allows companies to change their legal structure without dissolving their legal personality. However, the  process of Conversion of a Private Joint‑Stock Company to a public joint‑stock company requires compliance with specific legal conditions, procedures, and formalities. Failure to meet these requirements may lead to rejection of the conversion application.

This article reviews the conditions, procedures, and required documents for converting a private joint‑stock company into a public joint‑stock company in a practical and accessible way.

 

What Does Company Conversion Mean?

Company conversion means changing the legal form of a company without terminating its legal personality. In simple terms, the company remains the same legal entity but continues its activities under a different legal structure.

For example, when a private joint‑stock company converts into a public joint‑stock company:

  • The company registration number and national identification number remain the same.
  • Existing contracts remain valid.
  • The company’s assets, liabilities, and obligations remain unchanged.
  • No transfer of property or rights is required because the company’s legal personality continues uninterrupted.

Therefore, only the legal structure, governance rules, and method of capital raising change.

This distinction is legally important. Unlike dissolving a company and creating a new one, conversion does not require transferring assets, contracts, or licenses, which helps maintain stability in the company’s business relationships.

 

Differences Between Private and Public Joint‑Stock Companies

To better understand the conversion process, it is important to first understand the key differences between these two types of companies.

Some of the main differences include:

  • In a private joint‑stock company, all capital must be provided by the founders at the time of incorporation. In contrast, in a public joint‑stock company, part of the capital must be raised through public subscription.
  • The minimum capital requirement for a public joint‑stock company is 5 million rials, whereas for a private joint‑stock company it is 1 million rials.
  • The minimum number of shareholders required to establish a public joint‑stock company is five, while a private joint‑stock company requires at least three shareholders.

 

Legal Requirements for Conversion of a Private Joint‑Stock Company into a Public Joint‑Stock Company

Iran’s Commercial Code establishes several conditions for converting a private joint‑stock company into a public joint‑stock company. These requirements are designed to protect shareholders, creditors, and potential investors.

1. Approval by the Extraordinary General Meeting

The first requirement is approval of the conversion by the Extraordinary General Meeting of Shareholders.

Shareholders must convene the meeting in accordance with legal procedures and formally approve the conversion. The decision must be recorded in the official meeting minutes.

2. At Least Two Years Since Registration

At least two full years must have passed since the company’s registration before it can apply for conversion.

This requirement ensures that the company has engaged in genuine business activities and prevents the conversion of inactive or purely nominal companies.

3. Approval of Two Financial Statements

At least two balance sheets and profit‑and‑loss statements must have been approved by the general meeting of shareholders.

These financial statements demonstrate that the company has been financially active and has maintained a real operational record.

4. Full Payment of the Company’s Capital

The company’s registered capital must be fully paid.

If any part of the capital has only been pledged but not paid, the company cannot proceed with the conversion.

5. Compliance with Minimum Capital Requirements

The company’s capital must meet the minimum requirement for a public joint‑stock company.

The minimum capital required for establishing a public joint‑stock company is 5 million rials. Therefore, if the capital of the private joint‑stock company is below this threshold, it must increase its capital before conversion.

6. Amendment of the Articles of Association

The company’s Articles of Association must be amended to comply with the regulations governing public joint‑stock companies.

7. Obtaining Required Regulatory Approvals

Because the registration and public subscription of shares in public joint‑stock companies require authorization from the Securities and Exchange Organization of Iran (SEO), the conversion of a private joint‑stock company into a public one also requires approval from this authority.

8. No Tax Restrictions or Outstanding Tax Liabilities

The company must not have unresolved tax liabilities or legal restrictions resulting from its tax status.

In practice, the company is usually required to obtain relevant certificates from the tax authority before completing the conversion process.

9. No Judicial Prohibition

The conversion must not be prohibited by a court order or judicial decision.

If a legal restriction has been imposed on the company by judicial authorities, the conversion cannot be registered until the restriction is lifted.

 

Steps for Converting a Private Joint‑Stock Company into a Public Joint‑Stock Company

The conversion process involves several legal and registration steps that must be carried out carefully.

Step 1: Holding the Extraordinary General Meeting

An Extraordinary General Meeting is held in which shareholders decide on matters such as:

  • Conversion of the company into a public joint‑stock company
  • Amendment of the Articles of Association
  • Capital increase (if required)

Step 2: Preparing Legal Documents

The company must prepare all necessary documents for submission to the Companies Registration Office and other relevant authorities.

The documents must be complete and compliant with legal requirements, as incomplete documentation is one of the most common reasons for delays or rejection.

Step 3: Submission to the Companies Registration Office

The company must submit the required documents to the Companies Registration Office within one month from the date the conversion is approved by the Extraordinary General Meeting.

Step 4: Review by the Registration Authority

The Companies Registration Office reviews the submitted documents.

If deficiencies are identified, a deficiency notice will be issued, and the applicant will typically be given 10 days to correct the issues. If the documents are approved, the conversion is officially registered.

Step 5: Publication of the Conversion Notice

After registration, the conversion must be announced in:

  • The Official Gazette, and
  • The company’s designated widely circulated newspaper.

From this point forward, the company is officially recognized as a Public Joint‑Stock Company.

 

Required Documents for Converting a Private Joint‑Stock Company into a Public Joint‑Stock Company

Within one month after the Extraordinary General Meeting approves the conversion, the company must submit the meeting minutes along with the following documents to the Companies Registration Office:

1. Minutes of the Extraordinary General Meeting

The resolution approving the conversion and the amendment of the Articles of Association must be documented and submitted.

2. Amended Articles of Association

The revised Articles of Association must comply with the regulations governing public joint‑stock companies and must have been approved by the Extraordinary General Meeting.

3. Two Balance Sheets and Profit‑and‑Loss Statements

These documents must relate to the two financial years preceding the conversion decision and must be approved by the company’s certified public accountant.

4. Statement of Company Assets

This document must include an evaluation of all movable and immovable assets of the company and must be confirmed by an official court‑appointed expert.

5. Conversion Declaration

The conversion declaration must be signed by the company’s authorized signatories and must include the following information:

  • Company name and registration number
  • Company objectives and business activities
  • Registered office and addresses of branches (if any)
  • Total capital and the amount paid
  • Details of the board of directors and the managing director
  • Conditions for shareholder participation and voting rights in general meetings
  • If the company was established for a limited duration, the expiration date
  • Total liabilities of the company
  • The name of the widely circulated newspaper in which company notices are published

 

Legal Effects of Company Conversion

Converting a private joint‑stock company into a public joint‑stock company does not create a new company; it only changes the company’s legal form. To prevent disruption in the company’s business relationships, the law recognizes several legal consequences of this conversion.

1. Continuity of Rights and Obligations

The most important effect of conversion is that the company’s legal personality continues without interruption.

This means:

  • All existing contracts remain valid.
  • The company’s rights and claims against third parties remain intact.
  • All debts and liabilities remain enforceable.
  • Ownership of tangible and intangible assets—including property, equipment, trademarks, and licenses—remains unchanged.

For example, if a private joint‑stock company had signed a construction contract before conversion, the contract remains valid after the conversion, and there is no need to sign a new agreement.

Similarly, creditors retain the right to claim their debts from the company.

2. Continuity of Corporate Management

Another consequence of conversion is the continuity of the company’s governing bodies.

Typically, the company’s managers and board members remain in their positions after the conversion and continue managing the company.

However, the governance structure must comply with the rules applicable to public joint‑stock companies. For example:

  • In a private joint‑stock company, the board must have at least three members.
  • In a public joint‑stock company, the board must have at least five members.

Therefore, if the company previously had only three board members, additional members must be appointed after conversion.

3. Obligation to Indicate the New Company Type in Official Documents

After the conversion is registered, the company must indicate its new legal form in all official documents, including invoices, letters, contracts, and announcements, together with its existing national identification number.

For example, if the company name was previously:

“Pars Industrial Development Company (Private Joint‑Stock)”

after conversion it should appear as:

“Pars Industrial Development Company (Public Joint‑Stock) – National ID …”

This requirement ensures transparency for third parties, investors, and contractual partners.

 

Conclusion

Converting a private joint‑stock company into a public joint‑stock company is one of the most significant legal and strategic decisions in the growth of a business. It allows companies to access broader financial resources, enhance their credibility, and potentially enter the capital market.

However, the conversion process requires strict compliance with legal requirements, preparation of financial documentation, amendments to the company’s legal structure, and completion of registration and subscription procedures.

Any mistake in preparing documents or following legal procedures may lead to delays, rejection of the application, or even legal liability for company managers. For this reason, companies are strongly advised to seek specialized legal advice in corporate and commercial law before initiating the conversion process.
