About Karoon Energy

Karoon Energy Ltd is an oil and gas producer listed on the ASX. Its main producing assets are the Baúna project offshore Brazil and the Who Dat field in the US Gulf of Mexico. The company reports production in barrels and barrels of oil equivalent and sets calendar-year guidance.

Latest development

The share price information above is reported separately from the operational update. On 28 September 2026 Karoon announced an electrical fault at the SPS-92 well at Baúna. A fault on the monitoring system was noted on 21 September, the well was shut down in a controlled way on 22 September, and testing confirmed a fault in one of the three electrical phases in the newly installed power cable for the downhole electrical submersible pump.

The pump is operating on two phases in a conservative manner. Karoon believes a rig-based well intervention will be needed to replace the cable system and has an existing option over a suitable rig, with timing dependent on permits and services. About 3,500 barrels of oil per day are expected to be deferred until the cable is replaced, and the company does not expect the deferral to affect Baúna reserves.

As a result, 2026 Baúna production guidance was cut from 6.0–6.7 million barrels to 5.4–5.7 million barrels, with the lower end reflecting a possible conversion to gas lift. With Who Dat guidance unchanged, calendar 2026 total production is now expected at 6.6–7.2 million barrels of oil equivalent, and unit production cost guidance is US$15–16 per barrel of oil equivalent. Karoon said its insurance program may partially offset lost revenue and reimburse substantially all intervention and repair costs, subject to deductibles, policy terms and insurer confirmation.

Sector context

Offshore oil producers depend on subsea and downhole equipment that can fail, and repairs require rigs, permits and services, so interruptions are a recognised feature of the business. Oil-linked revenue also tracks crude prices, which are described in sector disclosures as having been elevated recently.

Insurance programs are commonly used to offset the cost of equipment damage and lost production, although recoveries depend on policy terms, deductibles and insurer confirmation, as Karoon noted in its update. Karoon’s mix of production in Brazil and the United States exposes it to different regulatory and currency settings.

Risks

The SPS-92 fault reduces 2026 output and raises unit costs because the cost base is relatively fixed. The timing of the repair depends on rig availability and permits, and insurance recovery is subject to policy terms and final confirmation of cover.

Karoon is exposed to oil prices, exchange rates and operating performance at its offshore fields.

Share price movements add a separate layer of uncertainty. The stock’s one-day move of -0.57% on 20 October 2026 compares with a 1.31% fall for the sector index, and its 12-month change of approximately +22.62% shows how far the share price can move over a year.

Catalysts to watch

Items to watch include the schedule for the rig intervention at SPS-92, any confirmation of insurance cover, Who Dat production against guidance and the company’s next quarterly report.
