Shares in GrainCorp Ltd (ASX: GNC) have come under heavy selling pressure following a cautious earnings update from the agribusiness group.
At the time of writing, GrainCorp shares are down 14.86% to $6.13, extending a difficult period for the stock.
Over the past year, the share price has struggled as global grain markets remain oversupplied and margins stay under pressure.
Let's take a closer look at the update.
What spooked investors today
In an ASX announcement released today, GrainCorp provided its first look at its FY26 earnings.
GrainCorp expects FY26 underlying EBITDA of $200 million to $240 million, reflecting softer margins across global grain markets. Underlying NPAT is forecast to be between $20 million and $40 million for the year.
Those figures exclude business transformation costs and the impact of the sale of GrainCorp Canada.
Management warned that FY26 earnings will be pressured by lower margins across the business. That reflects ongoing oversupply in global grain markets and continued pressure on export spreads.
Why margins are under pressure
GrainCorp said market conditions remain challenging across the East Coast Australia winter harvest.
Even though production volumes were strong, global grain supplies remain high. In turn, this is keeping prices low and putting pressure on margins across the supply chain.
Management noted that many growers are holding back on selling grain due to weaker prices.
As a result, GrainCorp expects margins on grain handled in FY26 to be lower, despite solid receival volumes.
Why less grain is expected in FY26
GrainCorp expects to handle between 10.1 million and 12 million tonnes of grain in FY26. This is down from 13.3 million tonnes in FY25.
The drop reflects a more normal harvest after a very strong year, along with ongoing weather uncertainty.
In its Nutrition and Energy businesses, GrainCorp expects results to be similar to FY25. However, earnings from Energy are likely to be lower due to uncertainty around US biofuels policy.
Cost control moves into focus
Management was quick to highlight cost control.
The company confirmed it is accelerating cost management initiatives while maintaining service levels to growers and customers.
GrainCorp's balance sheet remains strong, giving it flexibility to navigate softer conditions and continue executing its longer-term strategy.
Foolish Takeaway
GrainCorp shares are deep in the red today as investors react to softer margin guidance for FY26.
The outlook highlights ongoing pressure from global grain oversupply, weak pricing, and tighter export spreads. Those headwinds are likely to weigh on earnings in the near term.
However, GrainCorp still operates critical grain infrastructure and maintains a solid balance sheet. After a huge one-day sell-off, the big question is whether the market has already priced in much of the bad news.
