The company generated preliminary sales of EUR 1,347 million, which is 4.7 percent below the previous year ’s result (2024: EUR 1,412.8 million). This decline in sales is in line with the projected mid‑single‑digit percentage range. The wafer area sold developed positively in the reporting year and exceeded the level of the previous year. The volume trend was primarily supported by the increasing market momentum in the end markets over the course of the year which led to a stronger demand for 300 mm products. By contrast, the closure of the SD line (production of polished and epitaxial wafers with diameters of up to 150 mm in Burghausen) during the course of 2025 contributed to more than one-third of the negative sales deviation. Additionally, elevated inventories in the 200 mm

As a result, preliminary EBITDA decreased to EUR 317 million (2024: EUR 363.8 million). The EBITDA margin reached a solid level of 23.5 percent (2024: 25.8 percent), placing it within the expected target range of 22 to 24 percent. “Thanks to the consistent implementation of our strategy and the cost‑reduction measures we initiated, we achieved our 2025 targets. Demand impulses across many parts of the end markets – particularly driven by AI – provided support, while price effects and the product mix continued to weigh on the business environment. Excluding the closure of the SD line and the FX effects, our sales would operationally be on par with the previous year – which is a strong performance given the challenges,” commented Dr. Michael Heckmeier, CEO of Siltronic AG. Cost of sales increased year ‑over‑year due to the higher wafer volume and increased depreciation (EUR 343 million, 2024: EUR 238.5 million), in particular driven by the start of depreciation for major parts of our n ew fab in Singapore from August 2025. Among other things, improved fixed cost dilution and positive effects from cost -cutting measures had a reducing effect on cost of sales. Overall, earnings before interest and taxes (EBIT) declined significantly, as expected, amounting to EUR ‑ 26 million (2024: EUR 125. 2 million). The preliminary EBIT margin was ‑2.0 percent, compared to 8.9 percent in 2024. Improvement in net cash flow due to reduced capital expenditure Despite continued strong investments related to the new fab in Singapore, capital expenditure including intangible assets significantly declined to EUR 369 million on a provisional basis (2024: EUR 523.4 million). As a result, net cash flow improved to EUR -85 million (2024: EUR -297.0 million). Net financial debt amounted to a provisional EUR 837 million as of December 31, 2025 (2024: EUR 733.5 million).

eite 3 von 6 Business performance in Q4 2025 Preliminary sales of EUR 372 million in Q4 2025 were significantly above the level of Q3 2025 (EUR 300.3 million). This was due to delivery shifts from Q3 2025 and from early 2026 into Q4 2025. As a result, EBITDA in Q4 2025 increased to a provisional EUR 86 million (Q3 2025: EUR 65.8 million). The EBITDA margin on a preliminary basis was 23.3 percent (Q3 2025: 21.9 percent). EBIT amounted to a provisional EUR - 34 million (Q3 2025: EUR -31.4 million) . C apital expenditure in Q4 2025 was provisionally EUR 62 million (Q3 2025: EUR 85.5 million). The preliminary Q4 2025 net cash flow improved significantly quarter ‑over‑quarter to EUR 102 million (Q3 2025: EUR -30.6 million). In addition to an improved operating cash flow, this was mainly due to timing differences between the accounting of capex and the subsequent payment date in early 2026, as well as investment grants received in Q4 2025. Challenges expected to persist into 2026 Siltronic expects that 2026 will continue to present a challenging market environment, characterized by price pressure outside long‑term agreements (LTAs) as well as negative FX effects. While end markets in the 300 mm segment are growing, the 200 mm segment will remain under pressure this year due to still elevated inventories. The mentioned delivery shifts from early 2026 into Q4 2025 will also have an additional impact on performance, particularly in the first half of the year. Moreover, the effect of the SD line closure will be reflected in the full year sales for the first time. It is not yet possible to conclusively assess how these factors will affect the 2026 guidance, which is still to be determined. The company remains focused on continuing cost-reduction measures, active cash management, and disciplined investment management – without losing sight of its strategic positioning as one of the leading providers of high-tech wafer solutions. Once the assessment of the aforementioned headwinds on the current financial year is complete, the company will publish its 2026 guidance.
