Industry weakness impacts Siltronic's earnings in Q1 2023

  • Wafer area sold lower q-o-q, as expected

  • Sales decreased 14.3 percent to EUR 404.4 million q-o-q

  • EBITDA declined from EUR 168.1 million to EUR 125.2 million q-o-q

  • EBITDA margin at 31.0 percent in Q1 2023

  • Construction of new fab in Singapore proceeding according to plan

  • Guidance: Q2 sales at the level of Q1 2023, EBITDA margin between 27 and 31 percent, no recovery expected in H2 2023

Munich, Germany, May 11, 2023 – Siltronic AG (MDAX/TecDAX: WAF) reported a decline in sales of around 14 percent in Q1 2023 compared to Q4 2022. The reduction resulted from the lower wafer area sold and the stronger euro compared to the US dollar.

"After the record year 2022, demand for wafers was weaker in Q1 2023, as expected. Reasons for this development are the general economic slowdown, geopolitical uncertainties, and the consequences of inventory corrections at chip manufacturers and their customers," said Rainer Irle, CFO of Siltronic AG. "Nevertheless, we are convinced of the medium- and long-term growth of the industry. To accompany this, our focus is on the construction of the new 300 mm fab in Singapore, which is progressing with great strides and on schedule."

Business Development in Q1 2023

Siltronic generated sales of EUR 404.4 million in Q1 2023, a decrease of 14.3 percent versus Q4 2022. The decrease was primarily driven by the wafer area sold and secondarily by the strengthening of the euro against the US dollar. The euro to US dollar exchange rate averaged 1.07 in Q1 2023, a strengthening of 5.2 percent sequentially q-o-q (Q4 2022: 1.02).

The driver for the EUR 13.4 million lower cost of sales compared to the previous quarter was the lower wafer area sold. The associated cost savings were dampened by a disproportionately low decline in labor costs and by price increases for raw materials, supplies and energy.

The developments described above reduced the gross profit for Q1 2023 by EUR 54.3 million and EBITDA by EUR 42.9 million q-o-q. Foreign exchange hedging is the main reason why EBITDA developed better than the gross margin by EUR 11.4 million.

EBITDA in Q1 2023 was EUR 125.2 million, compared to EUR 168.1 million in Q4 2022. The EBITDA margin decreased from 35.6 percent to 31.0 percent.

When comparing EBIT in the reporting quarter with the previous quarter, it should be noted that Q4 2022 was positively influenced by the reversal of an impairment of a building in the amount of EUR 5.7 million. The writeup is recorded in other operating income. Additionally, it should be noted that Q1 2022 included a termination fee of EUR 50.0 million due to the failed tender offer by GlobalWafers. The termination fee was the reason for the higher tax rate in the same period of the previous year.

Rising market values of securities and interest effects had a positive impact on the financial result compared to the previous quarter and Q1 2022.

Although the semiconductor industry is currently in a weaker market phase, a remarkable profit for the period of EUR 72.5 million was achieved, compared to EUR 118.6 million in the previous quarter. Of this amount, EUR 66.1 million is attributable to Siltronic AG shareholders with earnings per share of EUR 2.20.

Development of equity, net cash flow and net financial assets

With equity of EUR 2,118.4 million on March 31, 2023, Siltronic AG's equity ratio was 51.1 percent compared to 51.0 percent on December 31, 2022. The increase in equity is based on the net income for the quarter of EUR 72.5 million. There were offsetting effects mainly from the currency translation of the foreign subsidiaries.

Lower interest rates have led to a slight increase in pension provisions of EUR 2.5 million. The interest rate in Germany fell from 3.72 percent at the end of 2022 to 3.66 percent at the end of Q1 2023. In the US, the interest rate also decreased from 4.90 percent to 4.68 percent during this period.

The decline in EBITDA of EUR 42.9 million is reflected in the cash flow from operating activities. Due to the continued very high cash outflows for capital expenditure including intangible assets, both the free cash flow at EUR -83.8 million and the net cash flow at EUR -105.6 million were negative in Q1 2023. In Q1 2023, customer prepayments of EUR 32.4 million were received.

On March 31, 2023 the company had net financial assets of EUR 284.1 million after EUR 373.6 million on December 31, 2022.


The start into 2023 was rather muted for Siltronic. Due to inventory corrections at chip manufacturers and their customers, Siltronic continues to expect temporary market weakness in the coming quarters. Customer postponements in delivery volumes will affect the entire year 2023.

In Q2 2023, we expect sales to be at the level of Q1 2023. The EBITDA margin is forecast to be between 27 and 31 percent (plan rate EUR/US dollar 1.10). We do not expect any recovery in the second half of the year.
