Melbourne — Orica Ltd. reported a 7 percent drop in net profits after taxes (NPAT), to A$601.6 million on revenues of $6.9 billion for the year ending Sept. 30, 2013, compared to 2012’s $650.2 million and $6.7 billion, respectively. Orica cited reduced demand for ground support products and explosives, partly offset by higher volumes in its Chemicals business. Chemicals and ground support both saw lower prices. For 2014, Orica believes NPAT will exceed 2013, but notes that volatile market conditions add a greater degree of uncertainty.
