IFA says STPI's 1.25-billion-baht capital increase at 5.55 baht per share is fair, as it pushes into data centers and clean energy
Beyond Securities, acting as the independent financial advisor to STP & I, or STPI, sees the plan to raise funds by allocating newly issued ordinary shares to specific persons, a private placement, as a connected transaction that is reasonable and benefits the company and shareholders as a whole, and believes shareholders should approve the transaction. STPI plans to issue and offer up to 225,897,120 new shares in total, split between a rights offering to existing shareholders of no more than 164,752,035 shares at a ratio of 11 existing shares to 1 new share at an offering price of 5.55 baht per share, worth about 914.37 million baht, and a private placement of no more than 61,145,085 new shares at the same price, worth about 339.36 million baht, for total fundraising of up to about 1,253.73 million baht. The private placement shares will be offered to Masthawin Charnvirakul, a director and managing director of STPI, who is a connected person. If existing shareholders exercise their rights offering in full, after the private placement allocation Masthawin will hold 61,145,085 STPI shares, or about 3% of all shares issued and outstanding after the capital increase. On the use of proceeds, the company plans to use about 900 million baht as part of its investment in a data center project and about 353 million baht to invest in and develop renewable energy projects, including a solar power plant project, with spending scheduled for 2026 to 2028. The 900-million-baht data center project is only part of the equity investment, with the STPI group expected to be responsible for its 26% proportionate share, totaling about 2,135.18 million baht, while the remaining roughly 1,235.18 million baht is expected to be raised from other funding sources under the project's investment plan. Of the roughly 353 million baht earmarked for renewable energy, the company expects to use about 256.94 million baht for the solar power plant project through Daisy Drive, comprising about 1.50 million baht for share purchases and about 255.44 million baht in investment for its 60% proportionate stake, while the remaining roughly 96.06 million baht will support other renewable energy projects in the future. On price fairness, the independent financial advisor assessed STPI's fair value at 4.63 to 6.50 baht per share using three appropriate valuation methods, while the capital increase offering price of 5.55 baht per share falls within that fair value range, and therefore views the offering price as fair. The 5.55-baht price is also about 9.35% below the reference market price of 6.12 baht per share. STPI plans to submit the agenda item to an extraordinary general meeting of shareholders, the first of 2026, on October 1, 2026. If approved, the private placement transaction must be completed within no more than three months from the date of the shareholders' resolution, or by December 31, 2026.

ASPS: STPI shifts to digital and clean energy, recommends Buy
Asia Plus Securities (ASPS) stated that STP&I Public Company Limited (STPI) is transitioning from its contract manufacturing and industrial structure business to digital infrastructure and clean energy through a capital increase of 1,253 million baht to invest in data centers and renewable energy, which will serve as a new long-term growth engine. The 110MW data center project has received BOI promotion and has secured power, water, and fiber optic connectivity, with construction expected to begin in Q4/2026. Q3/2026 profit outlook is strong, despite the core business slowing due to fabrication revenue being in a transitional period before new work begins and electricity revenue being in its low season, but it will be supported by special gains of several hundred million baht from the sale of ST Evolution shares worth 518 million baht to a partner. Meanwhile, Q4/2026 results will recover with revenue recognition from new projects and share of profit from Monsoon entering its peak season. STPI's value will be increasingly driven by data centers and renewable energy, with the company holding a 26% stake in the data center project. Additionally, there is a 55MW solar farm project on Plu Ta Luang land to support the clean energy needs of the data center, as well as a 5.99MW waste-to-energy plant in Phetchaburi expected to achieve COD by year-end, receiving an adder of 3.50 baht per unit for 7 years. The Monsoon Expansion plan of 1,000MW is also a long-term growth driver. Another key strength is the hidden asset from 937 rai of Plu Ta Luang land, which has a book value of only 320 million baht (0.34 million baht per rai) compared to a market price of around 2.8 million baht per rai, making the total land value potentially over 2.6 billion baht. The company also plans to sell about 100 rai of land for data center development, which will unlock asset value and support investment in new businesses. The current share price is trading below the capital increase price of 5.55 baht, limiting downside risk. The recommendation is "Buy" with a target price of 7.55 baht, based on the Adjusted Book Value method by adjusting the Plu Ta Luang land value to market price, which does not yet include the added value from data centers and the new energy portfolio.

STECON Q2 profit jumps 76%, while STPI swings to a loss
Stecon Group reported second-quarter 2026 net profit of 911 million baht, up 76% from the same period last year, with first-half profit of 1.258 billion baht, up 45% year-on-year, driven by higher gross profit from cost and expense control. Meanwhile, STP&I swung to a net loss of 22 million baht in the second quarter of 2026, compared with a net profit of 83 million baht a year earlier, after recognising a 57 million baht share of loss from an investment in a joint venture. The main cause was the Monsoon project, a 600-megawatt wind power plant in Laos, where the second quarter of 2026 was a low-wind period, leaving revenue insufficient to cover expenses and financing costs, resulting in a recognised share of loss of 65 million baht.
STPI raises 1.25 billion baht for data centres and renewable energy
STP and I Public Company Limited, or STPI, has announced an increase in registered capital to 509.54 million baht from 453.06 million baht, by issuing 225.89 million new shares to fund investments in data centre and renewable energy projects between 2026 and 2028. A total of 164.75 million shares will be offered to existing shareholders at a ratio of 11 existing shares to 1 new share, priced at 5.55 baht each, worth 914.37 million baht. The remaining 61.14 million shares will be placed privately with Mr. Masthawin Charnvirakul, a director and managing director of the company, at the same price, worth 339.35 million baht. The total fundraising amounts to approximately 1.25 billion baht. This move comes amid a wave of data centre investment in Thailand, with 36 projects having applied for investment promotion, worth over 728 billion baht. STPI also holds more than 1.4 million square metres of land awaiting development in the Bangna-Trad area and the Eastern Economic Corridor, which could be turned into solar farms to sell electricity directly to large power users under the Direct PPA scheme recently approved by the National Energy Policy Council. However, STPI shares closed on Friday, 24 July 2026, at 6.40 baht, down 4.48 percent from the previous day, with the offering price of 5.55 baht representing a discount of about 17 percent from the closing price before the announcement.

The company plans to use the proceeds for investments in data center and clean energy businesses. Yuanta Securities Thailand views the major shareholder's participation as reflecting progress on the data center investment plan, with an official partnership announcement expected soon.
