Gunkul Engineering Shares Rise 160 Percent on Higher Revenue and Profit

Shares of Gunkul Engineering surged 160 percent in the past year, returning chairman Gunkul Dhumrongpiyawut to Thailand’s Richest list after a three-year hiatus, Forbes reported. The SET-listed renewable power producer posted a 24 percent increase in net profit to 456 million baht in the first quarter of 2026, matching a similar rise in revenue to 2.6 billion baht.

The company is actively bidding for large-scale engineering, procurement and construction contracts for renewable power plants and holds an order backlog exceeding 100 billion baht.

Gunkul Engineering expects annual revenue to reach 10 billion baht in 2026, up from 8.5 billion baht in 2025 when more than a fourth of revenue came from electricity sales. The company is run by CEO Naruechon Dhumrongpiyawut, daughter of the founder. Gunkul Dhumrongpiyawut established the firm in 1982 as a supplier of electrical equipment.

He secured a contract from the Electricity Generating Authority of Thailand in 2007 to install a wind turbine and later developed solar power plants and wind farms in Thailand, Malaysia, Japan and Vietnam.
