IAS acts for CGH on cross-border sale of Pi Securities to Webull

IAS Advisory acted as Thai legal counsel to Country Group Holdings PCL (SET: CGH) on the sale of its controlling interest in Pi Securities PCL to Webull Holdings (Singapore) Pte. Ltd., a subsidiary of Nasdaq-listed Webull Corporation (Nasdaq: BULL).

Pi Securities is one of Thailand’s longer-established brokerages, with 50+ years in the local capital markets and businesses spanning equities, derivatives, wealth management, and depositary receipt issuance. The transaction is a significant cross-border sale of a licensed onshore securities platform and underscores continued international interest in Thailand’s regulated brokerage sector.

IAS Advisory advised CGH on Thai corporate and securities regulation, SET and shareholder processes, and the cross-border aspects of the sale.

The matter was led by co-founders Mr Ittinant Suwanjutha and Ms Patnatwipha Sasithiroj (formerly Siripen Kulworakulpitak), with substantial support from associates Mr Tataraj Indrasukhsri, Mr Thaveerath Rahardja, Mr Watthanai Riyapan, Mr Chanin Tinnakorn, and Ms Napassaporn Trakulroong.

IAS Advisory advises BYD on acquisition of Kingsford Securities

IAS Advisory is pleased to announce that it advised Beyond Securities PCL (SET: BYD), a listed Thai securities company, on its acquisition of Kingsford Securities and the related corporate restructuring of BYD into a holding company.

The restructuring supports BYD’s longer-term strategy of diversification beyond its traditional operations and of pursuing further investments and new business lines.

IAS Advisory advised on the overall transaction and restructuring architecture, performed legal due diligence, drafted and negotiated the transaction documents, and provided ongoing counsel on corporate, regulatory, and securities law matters throughout the acquisition and the holding-company conversion.

The work was led by co-founders Mr Ittinant Suwanjutha and Ms Patnatwipha Sasithiroj (formerly Siripen Kulworakulpitak), with essential support from legal associates Mr Tataraj Indrasukhsri, Ms Natpanee Pasuntaratum, Mr Thaveerath Rahardja, Mr Watthanai Riyapan, Mr Chanin Tinnakorn, and Ms Napassaporn Trakulroong.

IAS Advisory joins consultation hosted by the Office of the PDPC

IAS Advisory co-founding partner Mr Anuwat Ngamprasertkul and senior associate Mr Piniti Chomsavas, both PDPA specialists, recently joined a consultation hosted by Thailand’s Office of the Personal Data Protection Committee (PDPC). The consultation brought together lawyers and representatives from leading law firms and consulting organisations to provide feedback on the draft sector-specific guidelines and to discuss ways to raise PDPA compliance standards through cooperation between consultants and the PDPC Office.

Anuwat and Piniti shared their views on stakeholder collaboration and the draft sector-specific guidelines for 11 target industry groups, consisting of:

• ICT & Telecommunications;
• Transportation & Logistics;
• Energy & Public Utilities;
• Public Health;
• Education;
• Finance, Investment & Insurance;
• Tourism;

The consultation, which took place on 8th July 2026, focused on ensuring that the guidelines provide clear, practical, and sector-appropriate guidance on compliance with Thailand’s Personal Data Protection Act (PDPA). Once finalised, the guidelines are expected to reflect the PDPC’s expectations and serve as a key reference for businesses, while promoting consistent privacy practices and strengthening confidence in Thailand’s digital economy.

We are grateful to the PDPC for the invitation to share practical insights and support the development of helpful industry-specific guidance that will assist businesses in meeting their PDPA obligations more effectively. More importantly, this dialogue reflects the shared commitment of the PDPC and PDPA consultants to supporting and uplifting PDPA compliance standards in Thailand.
