Incitec Pivot Ltd., reported a 72 percent drop in first-half net profit after tax (NPAT) excluding individually material items to A$41.9 million from the year-ago $147.1 million. The company cited a $60 million impact from the Queensland rail outage on Phosphate Hill earnings and $16 million from increased costs, driven by elevated gas pricing following a third-part gas supply disruption to the St. Helens site. There was also a $65 million decrease due to the impact of significant outages at the Waggaman, La., ammonia plant. Australian fertilizer sales were down $21 million due to drought.
