Shares of GrainCorp, Australia's prominent grain handling company, tumbled nearly 20% after the firm slashed its earnings forecast for fiscal 2026. The company cited low global grain prices and pressure on export margins as key factors. This sharp decline sent the stock to a four-year low, underscoring investor concerns over the company's outlook.

The company expects underlying EBITDA to range from A$200 million to A$240 million, a significant drop from A$308 million in the previous year. Similarly, underlying net profit after tax is forecast between A$20 million and A$50 million, compared to A$87 million in fiscal 2025. These projections reflect a challenging environment marked by cyclical oversupply and subdued prices in global grain markets.

Despite a strong winter harvest on Australia’s east coast, slower grower selling and multi-year low export margins are expected to weigh heavily on earnings. GrainCorp anticipates receivals of 11.0 million to 12.0 million tonnes, down from 13.3 million tonnes last year, with exports expected to range from 5.5 million to 6.5 million tonnes.

The company is accelerating cost management initiatives while maintaining service levels, a move seen as crucial in navigating the current market challenges. Investors and analysts will be closely watching GrainCorp’s ability to execute these initiatives and weather the ongoing market pressures.
