Siltronic (WAF.DE) — 2025Q2 FY2025 Earnings Call Analysis

Accounting Beats, Cash Flow Burns

EBITDA margin expanded 370bps while revenue dropped 5%—thank the accountants, not the customers.

Thesis: Siltronic is a volume proxy in a value-driven AI market. The 'AI decoupling' means chip value soars while wafer area stagnates, leaving WAF with high fixed costs and no pricing leverage. Management is bridging the gap with aggressive accounting—capitalizing R&D and revaluing spare parts to manufactured EBITDA beats—while cash flow bleeds. FabNext depreciation starting in August adds structural drag before revenue arrives.

Verdict: SHORT — Conviction: MEDIUM

Catalyst: Q3 results where the 'non-operating' EBITDA boosters fade and the FabNext depreciation drag hits the P&L fully.

Key Risk: Memory inventory digestion completes faster than expected, triggering a cyclical volume snapback that bails out the high operating leverage.

The Tell: When asked about debt covenants, CFO Claudia Schmitt shut it down: 'We haven't communicated so far any contract details and we will stick to that. So we won't disclose any details here.' You don't hide standard covenant thresholds unless you're watching them closely.

Friction Level: HIGH_FRICTION — Bulls see FabNext as a coiled spring for 2026; Bears see a stranded asset with depreciation hitting the P&L before demand arrives.
