Precautions for Directors of IPO Candidates and Listed Companies in Thailand

Subscribe to Updates

In September 2025, Thailand’s Securities and Exchange Commission (SEC) accused a company listed on the Stock Exchange of Thailand (SET), including its current and former directors, of concealing material information in connection with its filing registration and draft prospectus. This recent enforcement action demonstrates the serious consequences of making false statements or appearing to conceal material information in IPO filings and ongoing disclosures. In addition to being subject to criminal penalties, such actions can impact the eligibility of directors and executives to serve and may cause lasting reputational damage.

Key Legal Risks

The Securities and Exchange Act B.E. 2535 (1992) (as amended) imposes strict liability for making false statements or concealing material information in IPO registration statements and draft prospectuses. In such cases, investors can claim for damages, and there are also criminal penalties, including imprisonment for up to five years and substantial fines, may apply to the company, its directors, and responsible officers. However, misstatements or omissions in IPO filings do not, by themselves, disqualify directors or executives from holding office, whether arising from an SEC accusation or even a final court judgment.

In contrast, for ongoing disclosures after listing, such as financial statements, annual reports, and meeting notices, false or misleading statements or concealment of material information can result in not only criminal liability but also immediate disqualification of directors and executives. If the SEC accuses a listed company or its directors or executives of such misstatements or omissions, those directors or executives are immediately disqualified from their positions, even before a final court judgment.

Director and Executive Qualifications

Directors and executives must meet the SEC’s specified standards of trustworthiness, as set out in the relevant rules. The SEC clearly defines characteristics that are considered to demonstrate a lack of trustworthiness. For ongoing disclosures, being involved in making false statements or concealing material information can immediately call into question their suitability to serve, and may hold other consequences, as noted above. However, grounds for disqualification do not extend to misstatements or omissions in IPO filings, regardless of final court judgment. Companies should be aware of these important distinctions and not assume that all disclosure violations are treated the same under the law.

Materiality Assessment

Information should be considered material if a reasonable investor would regard it as important, especially if it could influence the price or value of securities. Companies should carefully assess both the likelihood and potential impact of events, avoid selective disclosure, and seek expert advice when necessary to ensure a thorough and diligent process.

Ensuring Compliance

Accurate disclosure and strong governance are essential at every stage. Failure to disclose material information or making false statements can result in criminal liability, regulatory sanctions, and disqualification of directors. Proactive controls and transparent communication help reduce risk and support market integrity.

Boards, executives, and advisors should ensure that all disclosures are accurate, complete, and timely. Robust internal controls and clear documentation are essential to support compliance. Companies should also prepare contingency plans for leadership changes in the event of regulatory action, and maintain transparent communication with investors and stakeholders regarding regulatory matters and the company’s responses.

Throughout 2022, the Central Bank of Myanmar (CBM) has implemented a series of rules surrounding the compulsory conversion of foreign currency balances in the country. This began on April 3, when the CBM issued a notification directing foreign currency holders in Myanmar to convert their foreign earnings into Myanmar kyat (MMK), within one day, at the official exchange rate. Since then, the CBM has issued further clarifications and instructions for banks authorized to handle foreign currency, responded to some concerns from foreign investors by exempting certain foreign investment projects from the conversion requirement, and relaxed the currency conversion requirements for trade at the Chinese and Thai borders. The process has not been without some trial-and-error as well, with the CBM walking back some exemptions after they were enacted. Foreign investors and business owners, both in the country and abroad, have raised concerns about this centralized control of foreign currency flow and the depletion of foreign currency in Myanmar’s business community. To help readers understand the sometimes-surprising moves by the CBM over the past months, this article will summarize the key developments in the CBM’s efforts relating to foreign currency conversion. Establishment of Compulsory Exchange Requirement On April 3, 2022, the CBM issued Notification No. 12/2022 and Directive No. 4/2022 requiring nearly all individuals, companies, and other organizations in Myanmar to convert foreign-currency income received from abroad to MMK within one working day of receipt. These requirements took immediate effect for all transfers and applied retroactively to foreign currency balances already in the country. All authorized dealer (AD) banks (i.e., those licensed to exchange foreign currency) were instructed to convert foreign currency held in the foreign currency accounts of “internal residents”—which included locally registered companies, organizations, and offices; Myanmar branches of foreign companies; and individuals residing or established in Myanmar

Thailand’s Trade Competition Commission has amended the guidelines prohibiting large purchasers from setting unfair credit terms for small and medium-sized enterprises (SMEs). The new guidelines, which were published in the Government Gazette on August 17, 2022, revise the definition of SMEs and clarify the duties of concerned parties. The original guidelines, which took effect in December 2021, set a favorable maximum period for credit terms for SMEs selling products or services to a third-party purchaser. Prescribing longer credit terms than the mandatory period would constitute an unfair trade practice in violation of the Trade Competition Act B.E. 2560 (2017). In defining what businesses are considered SMEs, the guidelines set thresholds for the number of employees and amount of annual turnover. The amended guidelines maintain these thresholds, but the new guidelines require that both employee-number and turnover thresholds be met in order for a business to be considered an SME. In contrast, the original guidelines only required either the employee-number threshold or the turnover threshold to be met. This amendment will likely mean that fewer business operators qualify as SMEs. Accordingly, two types of businesses are defined as SMEs under the guidelines: Manufacturers of goods with up to 200 employees and an annual turnover of no more than THB 500 million (approximately USD 13.5 million); or Service providers or wholesale or retail businesses with up to 100 employees and an annual turnover of no more than THB 300 million (approximately USD 8.1 million). To benefit from protection under the new guidelines against unfair credit terms, SMEs must provide documents proving the number of employees and the amount of annual turnover to trade partners that purchase goods or services from them. The new guidelines come into force on September 16, 2022. For more information on the unfair credit term guidelines, or

Thailand’s Board of Investment (BOI) has extended its previously announced period for reduction of import duty on imported raw and essential materials for battery manufacturing for electric vehicles and other applications. The BOI’s announcement No. 5/2565 dated August 8, 2022, extended the reduction period to a maximum of five years. The BOI’s promoted activities list includes two battery-manufacturing business activities: Activity 4.8.3.1 – Battery manufacturing Activity 5.2.6.1 – High energy density battery manufacturing Qualifying battery manufacturers who have cell or module manufacturing processes are eligible for 90% import duty reductions on raw and essential materials that cannot be produced in Thailand. These reductions will be available on an annual basis, and are renewable for five years in total—up from the original two years. Existing projects (i.e., those which have the original two-year duration in their BOI certificate) can also benefit from the extension by preparing a project amendment form, along with a clarification letter and supporting documents, for submission to the BOI office. For more details on these customs duty reductions, or on any aspect of investment promotion in Thailand, please contact Charuwan Charoonchitsathian at [email protected] or +66 2056 5657, or Napassorn Lertussavavivat at [email protected] or +66 2056 5662.
