BOI Incentives & EV M&A: Structuring in the EEC
Evaluating BOI tax incentive continuity, continuation conditions, and fiscal value preservation within Thailand's Eastern Economic Corridor.
Executive Summary
Thailand's transition toward electric vehicle manufacturing is reshaping the Tier-2 and Tier-3 automotive supply chain across the Eastern Economic Corridor (EEC) spanning Chonburi, Rayong, and Chachoengsao. Institutional capital targeting this sector evaluates acquisition opportunities where projected cash flows often rely heavily on existing Board of Investment (BOI) promotional privileges.
For an acquirer of an EV-component manufacturer, the underwriting question is not simply whether BOI incentives exist on paper, but whether the target's existing promotion remains applicable after the proposed transaction and whether the remaining incentive value can be evidenced from the promotion terms, project conditions, and transaction structure.
The BOI Privilege Continuity & Transaction Structure
For promoted targets, the transaction structure can materially affect the continuity of BOI promotional privileges. Underwriting therefore requires verification of the existing promotion certificate, remaining tax and machinery privileges, project conditions, and whether the proposed transaction constitutes a shareholding change, business transfer, or merger under the applicable BOI framework.
Certain qualifying promoted activities may receive corporate income tax (CIT) exemptions of up to 8 years, subject to the applicable BOI category, promotion terms, and project conditions.
| Regulatory Condition | Documentary Evidence | Evidence State |
|---|---|---|
| Existing BOI promotion | Promotion certificate not provided | MISSING |
| Remaining CIT exemption period | BOI project records not provided | MISSING |
| Machinery incentive position | Promotion documentation not provided | MISSING |
| Proposed transaction structure | SPA / transaction documents not provided | MISSING |
| BOI continuation requirements | Applicable BOI framework | UNRESOLVED |
No incentive value is credited to the underwriting model until the applicable promotion terms, transaction structure, and remaining benefit period are sufficiently evidenced.
Under BOI guidelines, changes in shareholding structure and business transfers are subject to distinct notification and approval protocols. Failing to secure timely administrative acknowledgments can result in administrative complications regarding remaining tax holidays and import duty exemptions...
Furthermore, under updated standards, component suppliers must satisfy specific local-content thresholds and qualification rules to support downstream OEM offset obligations. Deal teams must evaluate whether transaction structures utilize asset transfers, dropdown mechanisms, or newly promoted NewCos...
EEC Industrial Zoning & Site Eligibility
Factory location within designated industrial estates in the EEC unlocks additional operational benefits, including potential CIT exemption extensions. However, industrial land availability and zoning compliance require rigorous verification prior to closing...
