Karoon Energy (ASX:KAR) Falls Almost 12% After Gulf of Mexico Setback Forces 2026 Production Cut

KEY POINTS

  • Karoon shares fell almost 12% to A$1.64 after the company cut its 2026 production forecast.
  • A damaged oil field in the US Gulf of Mexico will not be fully fixed until late 2027, so this year’s output will drop.
  • The good news: this is delayed oil, not lost oil, and Karoon’s Brazilian business is untouched.
  • The bad news: it lands as oil prices fall hard, so Karoon gets hit on both price and volume.

Karoon Energy (ASX:KAR) dropped almost 12% today after warning it will produce less oil in 2026 than expected. The cause was a problem at one of its US fields, and the timing was unlucky, with oil prices already sliding. At first glance, that looks alarming, but the detail tells a more balanced story.

What Went Wrong at Who Dat

Karoon part-owns an oil field in the US Gulf of Mexico called Who Dat. The operator, LLOG, says a failed riser on the field’s E manifold cannot be brought back online until the second half of 2027, much later than planned.

Because of that, Karoon cut its 2026 Who Dat forecast by around 40%, which pulled the whole company’s expected production for the year down to about 7.2 to 8.2 MMboe (million barrels of oil equivalent).

The key point for investors: this is oil being delayed, not lost. The plan is to remove the failed riser in the third quarter of this year and have the field back to full output by late 2027. The oil is still in the ground. Karoon just gets paid for it later, more than a year later. In our view, a delay like this is very different from losing the asset for good.

The Part Most People Are Missing: Brazil Is Fine

Most early news stories skipped something important. Karoon’s Brazil forecast has not changed at all. Its main Brazilian oil field hit a couple of small delays, but it is still expected to be back to normal around the middle of the year.

This matters because Brazil is the real engine of the long-term story. The cash it generates is still on track, and future growth options remain alive. In short, the damage is fenced off to a single US asset. That is the difference between a problem that breaks the investment case and one that simply slows it down. We believe this is the second kind.

Karoon Faces a Double Squeeze: A Lower Oil Price and Less Oil to Sell

The bad luck is the timing. The large majority of what Karoon produces is oil and other liquids, so its revenue moves closely with the oil price, making it one of the more oil-price-sensitive stocks on the ASX. And oil prices have fallen sharply this week, with US crude slipping towards US$80 a barrel after the US and Iran agreed to reopen a key shipping route. So in 2026, Karoon faces pressure on two fronts: weaker prices for the oil it sells and fewer barrels to sell.

For the positive case to work, two things need to go right: the field repair stays on schedule, and Brazil delivers by mid-year. The main risk is further delays or oil prices staying weak into 2027.

So the real question is simple. Does more than a year of delayed US oil really deserve an almost 12% fall when Brazil and the long-term plan are unchanged? To us, this looks more like a timing problem than a broken story. We would be careful jumping in straight away and would watch for the next repair update as proof that the fix is on track.
