Shares of PT Pertamina Geothermal Energy jumped 10.9% to IDR 965 on November 5 after the company posted its strongest nine-month results yet, forcing investors to reassess whether the stock's recent slide — down from IDR 990 just a week earlier — had been overdone. Pertamina Geothermal Posts Record Output and 21% Profit Jump — Can a $6 Billion Expansion Bet Justify the Rally?
Shares of Indonesia's dominant geothermal producer surged 10.9% to IDR 965 on November 5, a day after the company disclosed nine-month results that beat its own operational records. The question now: whether a stock that had been drifting lower all week can sustain momentum as the company enters a capital-intensive growth phase.
Profits Grew Twice as Fast as Revenue — and That's the Key Number
Net profit reached US$126.6 million in January–September 2026, up 21.4% year over year, driven by higher revenue and lower administrative expenses.
Revenue rose 10.5% to US$352.2 million, while operating profit climbed 17.4% to US$186.3 million. The gap between profit and revenue growth tells investors the company is converting more of each dollar earned into bottom-line gains — partly because general and administrative expenses fell 15% to roughly US$20 million. That kind of cost discipline matters when expansion spending looms.
Record Generation Shows the Existing Fleet Is Running Hot
Pertamina Geothermal generated 4,114 GWh of electricity through September , a nine-month record. Capacity factors at key sites like Kamojang hit 95–99%, far above the 75–80% global geothermal average. Higher utilization means the company is squeezing more output — and cash — from plants already built, giving it a financial cushion before new projects come online.
A Massive Spending Plan Hangs Over the Story
The company aims to nearly triple installed capacity from 727 MW today to 1 GW by 2028 and 1.8 GW by 2034.
That roadmap carries an estimated price tag of US$5.4–6.4 billion — roughly double the firm's current total assets of about US$3 billion. Near-term projects include new units at Lumut Balai, Hululais, and Lahendong. Investors are effectively betting that today's record cash generation can fund, or at least backstop financing for, a buildout of that scale without dilutive fundraising.
The Dividend Sweetens the Wait — for Now
Nordnet lists a 5.62% dividend yield , attractive in a sector where returns on new projects take years to materialize. But as capital spending ramps, shareholders should watch whether management preserves that payout or redirects cash toward drilling rigs. The earnings beat shows the engine is running; the open question is whether the road ahead is worth the fuel.
