RT wins new MEA work and posts profit turnaround, but backlog target cut

RT wins 1.1bn baht MEA contracts RT secured two new projects from the Metropolitan Electricity Authority worth a combined 1.1 billion baht, including a large underground cable conversion on Srinagarindra Road. This adds fresh work to its pipeline and supports future revenue, a clear positive for the stock.
This is the most concrete new contract win in the period, directly boosting RT's order book and future revenue.
First-half profit turns around RT reported first-half 2026 net profit of 26 million baht, up 129% from a loss last year, with revenue up 19% and strong operating cash flow. The turnaround shows the business is recovering and executing better, which supports investor confidence.
The profit turnaround is a key new financial result that changes RT's earnings picture and supports the share price.
Backlog target cut to 6bn baht RT now expects full-year backlog of 6 billion baht, down from the 7.5 billion baht target given in July, after the order book fell to 4.755 billion baht in June. The lower backlog means less future revenue visibility, a negative offset to recent wins.
The reduced backlog target is a real counterweight that investors need to know about, showing the order book is smaller than earlier hoped.
Construction sector recovery supports RT Thai construction stocks are active as Q2 profits grow across the sector, helped by faster government budget disbursement and data-center investment. RT's own Q2 profit rose 92%, and sector strength can lift sentiment and demand for its services.
Sector-wide recovery and government spending are external forces that can drive more work and better sentiment for RT.

PSGC's Laos coal supply chain drives record first-half profit and revenue

Coal supply chain powers record first-half results PSGC's first-half revenue jumped 458% to 7.29 billion baht and net profit rose 432% to 627 million baht, mostly from its Laos-Vietnam government-to-government coal supply chain. That business shipped 1.41 million tonnes, above plan, to two Vietnamese state energy firms, giving PSGC steadier, recurring income instead of lumpy construction work.
This is the core new financial event showing why PSGC's earnings and stock story have strengthened.
PSGC tops mai market profit rankings PSGC was named the most profitable company on Thailand's mai market for the first half of 2026, with profit up 317% from a year earlier. Being the top profit leader raises PSGC's visibility among investors and can attract more buying interest in the stock.
It shows external recognition of PSGC's earnings strength, which can support demand for the shares.
New pumped-storage hydropower study with Laos PSGC signed an agreement with Laos' state power utility and government to study turning existing hydropower plants into pumped-storage systems, a large-scale way to store electricity. It is a long-term project needing years of study, but it signals PSGC is expanding beyond coal into regional energy infrastructure.
It is a new strategic move that could broaden PSGC's future business and growth story.
Capital reduction and construction pipeline PSGC cut its par value from 2 baht to 1 baht, a technical step that does not change the number of shares or company value. Meanwhile, its construction projects are mostly finished or progressing, with about 2.4 billion baht of remaining revenue expected through 2571, which supports future earnings but is not new growth.
It explains a neutral capital change and the remaining construction revenue that partly offsets reliance on coal.
