Siltronic significantly increased sales and earnings in fiscal year 2018

  • Preliminary sales of EUR 1,457 million significantly higher than in the previous year (2017: EUR 1,177.3 million)

  • Preliminary EBITDA improved significantly to EUR 589 million and EBITDA margin to just above 40 percent (2017: EUR 353.1 million, 30.0 percent)

  • Preliminary EBIT of around EUR 498 million significantly higher year-on-year (2017: EUR 235.7 million)

Munich, Germany, January 31, 2019 - Siltronic AG, one of the world’s leading manufacturers of hyper pure silicon wafers, showed an outstanding performance in 2018 and slightly exceeded the revenue target and profit expectations.

According to the preliminary and unaudited figures, sales of EUR 1,457 million were significantly higher year on year (2017: EUR 1,177.3 million). EBITDA came in at EUR 589 million, up about 67 percent year on year (2017: EUR 353.1 million). The EBITDA margin came in at roughly 40 percent (2017: 30.0 percent). In a very favorable market environment the company was able to increase the average selling prices again in 2018.

Preliminary earnings before interest and tax (EBIT) of around EUR 498 million more than doubled year on year (2017: EUR 235.7 million).

The ongoing execution of the cost reduction programs introduced back in 2010 enabled the company to compensate cost increases in the fiscal year 2018.

In 2018, Siltronic invested EUR 254 million in property, plant and equipment and intangible assets. Apart from a base capex of roughly EUR 90 million the company invested in additional 300 mm capacities and a new crystal pulling hall in Singapore. Siltronic also made some minor advance payments for production equipment which was already ordered for a capacity increase in 2020. The additional wafer capacity of both expansion steps in 2019 and 2020 has already been fully sold to customers based on long-term contracts.

The preliminary net cash flow of EUR 240 million nearly doubled compared to 2017 (EUR 124.8 million).

As a result, preliminary net financial assets increased to EUR 691 million (2017: EUR 342.1 million).

“2018 was a very successful year. Demand for our wafers was very strong as in 2017 and we were able to increase again the average selling prices,” said Dr. Christoph von Plotho, Chief Executive Officer of Siltronic AG.

Very strong sales in the fourth quarter of 2018

At around EUR 388 million of preliminary sales in Q4 2018, the company continued the very positive performance of the first 9 months of the year. Ongoing high capacity utilization and a sequential increase in prices contributed to this performance.

The company reported preliminary EBITDA of EUR 161 million in Q4 2018 driven by price increases compared to EUR 160.2 million in Q3. The preliminary EBITDA margin in Q4 2018 was around 41 percent (Q3 2018: 42.2 percent).

Macro-economic and political uncertainties influence market development in 2019

The market research institute IHS Markit currently anticipates that demand for silicon wafers for the semi-conductor industry will grow by roughly 4 percent in 2019.

According to Siltronic the underlying growth trend for silicon area is intact. However, expectations in the semiconductor industry are muted in 2019 due to the macroeconomic and political uncertainties. The company expects that 2019 will start cautiously, particularly in the memory and foundry business. However, logic, power applications and image sensors should stay strong.

The demand for wafers in Q1 2019 is slightly lower than in Q4 2018.

Following two outstanding years, Siltronic expects a more muted business development in 2019.
