Complete event summary combining all related documents: earnings call transcript, report, and slide presentation.Q3 2025 earnings summary28 Oct, 2025
Executive summary
Q3 2025 was the weakest quarter, impacted by expected volume shifts into Q4 and adverse FX effects, with demand remaining soft in a challenging market environment.
Active cost and cash management measures were implemented, including strict CapEx discipline and a comprehensive cost program, to maintain resilience and align production with demand.
Market share remained stable year-to-date, reflecting resilience despite headwinds.
Positive long-term growth signals from AI and memory markets, though short-term effects are limited by inventory normalization.
Financial highlights
Q3 2025 sales were EUR 300 million, down 8.7% sequentially, mainly due to lower wafer area sold and FX headwinds.
EBITDA was EUR 65.7 million (margin 21.9%), down from EUR 86.4 million (26.3%) in Q2, impacted by lower sales and ramp-up costs for the new Singapore fab.
EBIT fell to EUR -31 million, and net income was EUR -44 million, reflecting higher depreciation from the new fab.
CapEx totaled EUR 90 million in Q3, with year-to-date CapEx at EUR 339.1 million.
Gross margin turned negative at -1.2% in Q3, compared to 18.3% in Q2.
Outlook and guidance
Full-year 2025 guidance confirmed, with sales expected mid-single digits below 2024 levels due to FX headwinds.
EBITDA margin guidance narrowed to 22%-24% (from 21%-25%), with significant decline expected due to new fab depreciation.
Depreciation forecast refined to EUR 340-360 million; CapEx expected at EUR 360-380 million.
Cash flow projected to improve versus last year but remain negative due to high investment activity.

One of the very few apps you could call perfect. If something was to add to it, maybe the share price of the company when you search for it, but it's already excellent.
