Delta Electronics Thailand Holds SET Market Cap at 3.2 Trillion Baht as Domestic Data Centre Projects Pause

BANGKOK — Thailand's new data centre policy board ordered a pause on 166 projects at its first meeting on Sept. 4. The decision covers 49 sites under construction and 117 awaiting permission, while four subcommittees spend a month drafting national standards.

The country's largest listed company makes power and cooling equipment for data centres. It is unlikely to feel much impact.

Delta Electronics (Thailand) PCL had a market capitalisation of about 3.24 trillion baht, according to the Stock Exchange of Thailand's own factsheet dated March 23 — far larger than any other Thai company. Its business centres on power management, including server power supplies, cooling systems, modular data centre designs and the electrical hardware underpinning AI computing.

The reason the domestic pause is unlikely to affect it significantly is geographic. Delta manufactures in Thailand but sells to markets worldwide. Its largest revenue market is the United States, followed by Singapore, Germany and Taiwan. The customers driving its order book are global cloud operators building facilities in North America and Europe, not the developers whose Thai sites have been ordered to stop.

The scale of the business

Delta reported record first-quarter revenue of 61.38 billion baht in 2026, which chief executive Victor Cheng said represented a 56.2 percent year-on-year increase, along with net profit of 9.08 billion baht. Power electronics accounted for 71 percent of revenue, while gross margin reached 31.7 percent.

Cheng attributed the growth to strong orders, high output and expanded capacity, with data centre products the key driver. Delta has described Thailand as its main focus for capital expenditure and capacity expansion.

Full-year 2025 revenue was around US$6 billion. The company surpassed a US$100 billion market capitalisation in February.

Who the pause actually hits

The businesses exposed to a halt in Thai data centre construction are different, and are mostly domestic.

Power producers are first in line. Bangkok's six applications each required between 9 and 23 megawatts, and the pause covers projects at every stage, from foundation work to filed paperwork. Global Power Synergy appeared on a panel on data centre energy readiness at an industry summit in Bangkok in August, alongside Bangkok Bank — a pairing that indicates where the financing and power-generation exposure lies.

Construction firms, industrial estate operators, landowners and local subsidiaries of overseas operators are also exposed. None can bill for a project that is not being built.

Delta sits above all of that. It sells components into a global buildout; Thailand is primarily its manufacturing base, not its main sales market.

The concentration problem

This creates an unusual situation for investors holding Thai equities.

The SET Index had risen by nearly 30 percent since the start of the year, according to the exchange's own account in late August, with foreign investors recording net purchases of 67 billion baht. Delta has been a substantial contributor to that performance. Its shares have also moved sharply: the exchange's March factsheet records a 52-week range of 51.25 to 292.00 baht, with the stock at 260 baht.

An index driven higher by one company's earnings is not diversified in the way an index normally suggests. Buying exposure to the Thai market currently means taking a large position in a single manufacturer whose demand is driven by capital expenditure decisions in the United States and Europe.

That is our reading of the numbers rather than an analyst's assessment, but the underlying figures come from the exchange itself.

What the valuation assumes

The March factsheet also records a price-to-earnings ratio of 130.70, a price-to-book ratio of 33.53 and an enterprise value-to-EBITDA multiple of 88.31.

Those figures price in sustained growth for years. They also leave the shares sensitive to anything that disrupts the AI infrastructure cycle — and Delta's own reporting has flagged such risks. Analyst commentary in August pointed to an inventory provision charge of 800 million baht in the second quarter, linked to delays in project timing, and to the possibility of a repeat if customer drawdowns slow.

Conflict in the Middle East affecting logistics and petroleum-based inputs, as well as sanctions affecting Chinese semiconductor suppliers, have both been identified as risks to shipment schedules.

The argument the pause does not settle

There is one version of Thailand's AI ambition in which the country hosts the computing infrastructure. Another sees Thailand manufacturing the equipment while hosting comparatively little of it.

Thailand is currently succeeding at the second and has just paused the first. The pause is defensible on its own terms — the standards are genuinely absent, and a data centre that had not yet opened was found this week discharging fuel into a public drain in Bangkok. But the two facts sit side by side, and the country's largest company is positioned on the side that does not depend on domestic construction.

What to watch

Delta's third-quarter results and any commentary on Thai demand. The company has not been reported as citing the domestic pause as a factor. If its guidance remains unchanged, that would confirm the gap in exposure. If it does not, the pause may be reaching further than currently appears.

Whether Global Power Synergy or lenders disclose affected exposure. Power producers and banks with data centre commitments have a clearer route to material impact than equipment makers, as well as disclosure obligations that may bring such exposure to light.

Whether the SET's listing reforms bring data centre operators to market. The exchange eased its criteria from Sept. 11 and has been targeting data centre and semiconductor companies for listings. Whether any of them list while the sector is paused will be a real test of both policies.
