Siltronic sales and earnings in 2019 in line with expectations

  • As expected, preliminary sales of EUR 1,270 million in 2019 are significantly lower than in 2018 (EUR 1,456.7 million)

  • Preliminary EBITDA fell to EUR 409 million and the EBITDA margin to a good 32 percent (2018: EUR 589.3 million; 40.5 percent)

  • Preliminary EBIT of around EUR 298 million also significantly below the previous year (2018: EUR 497.7 million), as expected

  • Second-best year in Siltronic’s history

Siltronic AG, one of the world's leading manufacturers of hyperpure silicon wafers, reported a noticeable decline in sales and earnings in 2019. While 2018 was a record year in terms of earnings, 2019 has once again shown how quickly the market environment can change. Due to high demand, sales volumes in the fourth quarter of 2018 were still at a record level. At the turn of 2018/19, the environment deteriorated significantly. Negative factors such as the trade dispute between the USA and China put a burden on consumer climate and economic growth in many regions. Many customers massively slowed down their wafer starts at the beginning of 2019, causing the demand for wafers to drop by a double-digit percentage. Similarly, Siltronic AG's sales declined by about 13 percent. Due to poorer utilization of production lines and significantly higher energy costs in Germany, the EBITDA margin also declined to about 32 percent.

Despite this decline in sales and earnings, Siltronic AG is reporting 2019 as the second-best year in its history.

Average selling prices at the beginning of the year were still higher than in 2018, but then fell slightly in the second half of the year. Due to the strong US dollar, sales prices translated into euros were slightly higher on average in 2019 than in 2018. The decline in sales resulted mainly from lower volumes. The decline in demand affected all wafer sizes, but was more moderate at 300 mm than at 200 mm. The small diameters were most affected. Demand from the logic and foundry business remained good at 300 mm. Despite initial positive news in the first weeks of 2020, a revival of demand from the memory sector is not expected in the short term due to high customer inventories.

According to preliminary and unaudited figures, revenue in 2019 amounted to approximately EUR 1,270 million, significantly below the previous year (2018: EUR 1,456.7 million). EBITDA reached EUR 409 million and was thus around 31 percent below the previous year (2018: EUR 589.3 million). The EBITDA margin reached a solid 32 percent (2018: 40.5 percent).

At around EUR 298 million, preliminary earnings before interest and taxes (EBIT) were down significantly on the previous year (2018: EUR 497.7 million). The EBIT margin for 2019 is around 24 percent compared to 34.2 percent in 2018.

Due to the burden of special factors such as the discontinuation of the EEG hardship regulation (increase in energy costs of around EUR 20 million), a slight increase in costs was recorded - despite ongoing and effective savings programmes.

In 2019, Siltronic invested around EUR 360 million in property, plant and equipment and intangible assets. In addition to the base investments of around EUR 90 million, this includes expenditure for the new ingot pulling hall in Singapore. Furthermore, the good financial situation of recent years was used to make important investments in automation, digitization and capabilities. This will secure and further expand Siltronic's position as one of the technology leaders.

As a result of the increased investments, the preliminary net cash flow for 2019, at around EUR 81 million, was significantly lower than in 2018 (EUR 240.4 million), but exceeded expectations.

Despite the positive net cash flow, preliminary net financial assets declined to EUR 589 million (2018: EUR 691.3 million) due to the high dividend payment and the return of customer prepayments.

"2019 was a challenging and exciting year. Since we have little influence on the demand for our wafers, our focus has been and continues to be on our technological performance, increasing our productivity and optimizing processes through digitization," said Dr. Christoph von Plotho, CEO of Siltronic AG.

Sales development in the fourth quarter of 2019

Preliminary sales of around 304 million euros in the fourth quarter of 2019 were slightly above expectations, due in part to increased sales of wafers to customers who could not be served at times of full capacity utilization. The average selling price declined slightly in the fourth quarter.

Siltronic achieved a preliminary EBITDA of around EUR 90 million in the fourth quarter of 2019. EBITDA for the third quarter of 2019 was EUR 91.5 million. The preliminary EBITDA margin from October to December 2019 reached about 30 percent (Q3 2019: 30.5 percent).

Macroeconomic and political uncertainties continue to influence developments in 2020

Possible negative factors for 2020 continue to include geopolitical and global economic developments such as the trade dispute between the USA and China, which has not yet been fully resolved, and tensions in the Middle East. Currently, it is difficult to predict the effects due to the outbreak of the corona virus.  At the micro level, customers' high inventory levels will have a negative impact on the development of demand in 2020. In some segments, such as logic, market observers and customers report improved demand for semiconductors. A recovery in demand from the memory sector could be longer to come due to still high inventories of raw wafers.

Against this backdrop, the company assumes that the 2020 financial year will see a slow start.
