GrainCorp's shares dropped 13.5% on the back of investor disappointment with margin compression driven by a global oversupply of grains and a cautious outlook on grower selling activity and input pricing pressures. Despite reiterating full-year earnings guidance, concerns around subdued market conditions and margin pressure weighed heavily.

• Reported underlying EBITDA was $136 million for the half, reflecting operational resilience but margin headwinds from oversupplied grain markets.
• Bulk materials handled increased from 1.2 million to 1.5 million tonnes, while animal nutrition sales rose modestly to 390,000 tonnes.
• Elevated input prices and geopolitical uncertainty in the Middle East compressed margins and reduced grower selling activity.
• Management reaffirmed FY26 earnings guidance of $200–240 million, signaling caution amid ongoing adverse market dynamics.
• Cost reduction and portfolio optimization programs continue, including the pending sale of the GrainsConnect Canada joint venture to improve returns.
