SDI Limited provided earnings guidance for the six months ended 31 December 2017. The company expected sales to be AUD 33.6 million, down 2.2% on the previous corresponding period of AUD 34.4 million. When adjusted for currency movements, sales are expected to be down 1.5%. Despite a strong performance in Aesthetics sales (40% of Australian dollar sales), which recorded growth in Australian dollars of 8.2%, the overall Australian sales were impacted by weaker than expected Amalgam sales, which fell 15.3% in Australian dollars for the half year. The company expected after tax profit to be in the range of AUD 1.0 million to AUD 1.3 million, compared with AUD 2.0 million for the same period last year. Due to the Company's substantial natural hedging, currency movements are not expected to have a material impact on the result.
