What the build-out is worth

How this was counted

1. One figure per plant: the largest project investment it has published. A company that announced two phases separately is therefore counted once, at its larger figure, and is understated rather than doubled.
2. Registered capital, paid-in capital, an acquisition price and an equipment purchase are not project investment. They are recorded against the plant and excluded from the totals.
3. A parent's regional or global programme is not money in Thailand. One record names a Southeast Asia plan of RMB 10 billion alongside a Thai plant of RMB 1.2 billion; only the plant is counted.
4. A figure restated in a second currency inside brackets is one investment, not two.
5. Nothing is converted. Totals are reported per currency, as announced, because a single converted number across five currencies and four years would invent a precision nobody can check.

Coverage: 27 plants disclose a project figure, 3 disclose only capital or an acquisition, and 9 disclose nothing. Every row carries its sources: 325 across the register. 17 plants have a traceable BOI promotion, 21 publish a site area and 21 publish a capacity.

The register

Every figure is quoted as its source published it, with the qualifier the source used. Sources are company announcements, stock exchange filings, Board of Investment approvals, industrial estate notices and the Thai company register, listed in full on each plant's page. Public sources only, no personal data. An announcement is a statement of intent: it is not a certificate, a disbursement, or a plant.
