Karoon Energy's Oil Leverage Meets a Production Setback and Recovery

A conflict-driven oil price spike rewarded the ASX's purest oil play, before a subsea equipment failure tested the thesis, and July brought signs of genuine recovery.

Karoon Energy, described by Seneca Financial Solutions as the most leveraged stock on the ASX to a rising oil price, rallied 36 percent in March as the Iran conflict spiked oil prices, before a subsea equipment failure at its Who Dat field forced a production downgrade that combined with falling oil prices to drive a 26 percent decline in June, testing a genuine oil leverage thesis that has since been partly restored by a strong July operational update.

The purest oil leverage on the ASX

Spheria Asset Management said the stock returned 36 percent, benefiting from its leveraged exposure to higher oil prices, describing Karoon as an upstream oil producer with 100 percent operated production from the Baúna project in Brazil's offshore Santos Basin and a roughly 30 percent non-operated interest in the Who Dat field in the US Gulf of Mexico. Ellerston Capital called it one of the purest oil exposures on the ASX, having experienced operational problems that year due to a production leak, with expansion plans for a new Neon oil project in Brazil yet to find a partner. Acorn Capital said the stock rose 29.34 percent in response to a sharp oil price increase when the Iran war began, with some upside curtailed after the Brazilian government announced a 12 percent crude oil export tax, though it remained positive given Middle East production levels are likely to take several months to recover. Cooper Investors said Karoon has deep water fields in both Brazil and a minority interest in Who Dat, making it one of the most leveraged stocks on the ASX to oil prices.

Karoon is the most leveraged stock on the ASX to a rising oil price. Energy sector benefits from years of underinvestment meaning supply growth is relatively stagnant.

A jurisdictional risk skeptic, and a Brazilian export tax

Datt Capital rated the stock a sell purely due to jurisdictional risk, pointing to Brazil's 12 percent export tax on crude oil, which effectively ensures crude is kept for domestic refineries rather than exported, and while the tax is short duration at around 90 days, there is potential for it to recur. Acorn Capital called it probably a hold, having been probably a buy the day before given unfolding events, arguing that even if a ceasefire proves successful, it would take considerable time to restart Middle East oil production, meaning producers like Karoon should benefit through the June quarter and possibly beyond.

Karoon is a sell for me, and that's purely due to the jurisdictional risk. We've seen that Brazil enacted a 12% export tax on crude oil. What that does effectively is it's the upstream oil producers effectively ensuring the crude is kept and sent to domestic refineries.

A production downgrade compounds falling oil prices

Sandon Capital said Karoon downgraded CY26 production guidance to 7.2 to 8.2 million barrels of oil equivalent from 8.1 to 9.2 million, due to delayed reinstatement of production at Who Dat, though it also announced restoration of production from the Baúna SPS-92 well following a successful intervention, albeit at higher capital expenditure than expected. Spheria Asset Management said the stock fell 26 percent, driven by both a fall in oil prices and the company-specific downgrade, after a piece of subsea equipment failed at one of Who Dat's key production points. Collins St Asset Management said it reduced its Karoon position as part of trimming oil and gas exposure amid heightened volatility driven by US-Iran tensions, redeploying proceeds into CSL at what, in hindsight, proved a highly attractive inflection point for both the energy sector and CSL.

An operational recovery begins

Sandon Capital said Karoon provided an encouraging production update, with the Baúna operation in Brazil now operating near capacity at around 22,000 barrels a day following a major FPSO revitalisation and maintenance campaign, alongside restored production at the SPS-92 and PRA-2 wells, while in the Gulf of Mexico the Who Dat A1 sidetrack came online in mid-July, with a final investment decision on Who Dat East expected soon.

What fund managers say they are watching next is continued production recovery toward the top of revised CY26 guidance, the Who Dat East final investment decision, resolution of the Brazilian export tax situation, and whether oil prices stay supportive of the leverage thesis Seneca and others have highlighted.
