Darma Henwa Drops 31% in a Week as Jakarta's New Export Power Grab Raises a Blunt Question: Can Coal Contractors Survive the Squeeze?
Shares of PT Darma Henwa Tbk (DEWA.JK) cratered from IDR 484 to IDR 334 over five trading sessions — a 31% wipeout — after President Prabowo announced sweeping regulations to centralize Indonesia's commodity exports under state control. For a coal mining contractor already operating on thin margins, the timing could hardly be worse.
Jakarta Wants a Middleman Between Miners and the World
On May 20, Prabowo told parliament his administration had issued a regulation on the governance of natural resource exports.
Exports of coal, palm oil, and ferro alloy products will be integrated into a centralized system coordinated through PT Danantara Sumberdaya Indonesia (DSI), a state enterprise under Indonesia's sovereign investment structure.
Exporters fear profit margins could come under pressure, companies may lose pricing flexibility, and operations could become less efficient with additional bureaucratic layers. For Darma Henwa, which earns its fees from the coal miners who export, any margin compression upstream rolls directly downhill to contractors.
The Regulation Stacks on Top of Already-Rising Costs
Export levies of up to 5% already reduce net realized pricing, while royalties linked to Indonesia's coal benchmark increase as prices rise.
Proposed windfall taxes may further reduce retained margins, although implementation has been delayed. This layered burden means Darma Henwa's clients — chiefly Kaltim Prima Coal and Arutmin Indonesia — face shrinking incentives to ramp production, directly threatening the contractor's volumes.
A Big Contract Provides a Floor — But Not a Ceiling
In January, Darma Henwa signed a life-of-mine contract extension with Arutmin worth IDR 10.5 trillion for the Kintap and Asam-Asam projects.
The company will strip approximately 252 million bcm of overburden and produce around 50 million tonnes of coal over the mine life. That secures volume, but not pricing power — contractor fees can be renegotiated downward if miners' own margins shrink.
The Margin Turnaround Story Just Got Riskier
Darma Henwa was transitioning from subcontractor-heavy operations to owning most of its fleet, with EBITDA margins projected to expand from 14.2% in 2024 to 26.4% in 2025 and 40.9% by 2027. Those projections assumed a stable regulatory backdrop. Analysts say coal is likely to become one of the most sensitive sectors as the government moves toward a fully mandatory centralized export structure beginning in 2027 — precisely when Darma Henwa's profit transformation was supposed to peak. Investors are now repricing that bet with blunt force.
