Private vs. Public Companies in Thailand: What Newly Converted Public Companies Need to Know Part 1

Highlights

Private vs. Public Companies in Thailand

1. Meetings

  • Private: Flexible (Articles of Association governs).
  • Public: Strict notice (3–14 days), newspaper publication, minutes within 14 days.


2. Filings

  • Private: File financial statements + shareholder list with DBD only.
  • Public: Financial statements + annual report + newspaper publication, longer shareholder list deadline.


3. Capital Increase

  • Private: Installment share payments, no below-par issue.
  • Public: Full payment, may issue below par (with strict conditions), must publish in newspaper.


4. Capital Decrease

  • Private: 30-day creditor objection.
  • Public: 2-month creditor objection, mandatory newspaper publication, stricter DBD filings.


Bottom line:
Public Companies = stricter timelines, mandatory publications, stronger governance & creditor/shareholder protection.

Thailand’s corporate legal framework distinguishes between Private Limited Companies (“Private Company”), which are governed by the Civil and Commercial Code (the “CCC”) and Public Limited Companies (“Public Company”), which are regulated under the Public Limited Companies Act B.E. 2535 as amended (the “PLC Act”). These two company types serve different roles in the economy, Private Company is typically used for closely held businesses with a limited number of shareholders, restrictions on share transfers, and comparatively simpler governance structures. In contrast, a Public Company is intended to facilitate broader capital raising, including access to public offerings of securities, and is subject to more rigorous governance, disclosure, and shareholder protection requirements.

Both Private Companies and Public Companies are required to register with the Department of Business Development (the “DBD”), which serves as the primary regulatory authority overseeing their incorporation, and ongoing corporate filings. For Public Companies, however, the regulatory framework extends further once a Public Company offers securities to the public or seeks a stock exchange listing, it becomes subject to the Securities and Exchange Act B.E. 2535 (as amended) (the “SEC Act”), together with the rules and supervision of the Securities and Exchange Commission (the “SEC”) and the Stock Exchange of Thailand (the “SET”). This additional layer of regulation, through the oversight of the SEC and the SET, reflects the heightened standards of transparency, corporate governance, and accountability required of companies that raise capital from, and are accountable to, the investing public.

Most companies in Thailand are initially established as Private Companies and may subsequently be converted into Public Companies when they wish to issue securities to the public. The purpose of this article is to highlight the key differences between the two company forms, with particular emphasis on matters under the purview of the DBD, so that companies which have only recently been converted to Public Company status can better understand their new compliance obligations and regulatory environment.
