Siltronic raises €170M in share sale after a 54% rally

What's the deal? SiltronicDealroom has a profile for this one. Try Dealroom → (XTRA:WAF) has completed a €169.95 million follow-on equity offering, selling 2,200,000 ordinary shares at €77.25 each. The German wafer maker priced the post-IPO raise through a subsequent direct listing.

What does Siltronic do? It makes the hyperpure silicon wafers that sit underneath virtually every advanced semiconductor. It is one of only five companies controlling roughly 90% of the global wafer market — a picks-and-shovels play on AI, semiconductors, and electrification.

Why now? The raise follows a strong run: shares are up 54.12% year to date, with a one-year total shareholder return of 45.56%. Momentum has since cooled, with the stock down 15.03% over 90 days to €78.60.

How big is the raise? By deal-size percentile, the round sits at roughly the 45th percentile — mid-pack for this type of financing. The fresh capital issued at €77.25 lands just below the current €78.60 trading price.

What could go wrong? The bull case cracks if wafer pricing stalls or if further heavy spending and capital raises dilute shareholders more than expected. Valuation is also contested: one followed narrative pegs fair value at €138.26, calling the stock 43% undervalued, while the SWS DCF model points to €63.96 — an overvalued signal.

The signal: Siltronic is tapping public markets to fund build-out just as wafer volumes recover and depreciation nears a peak. The split sentiment — same cash flows, opposite conclusions — captures how investors are recalibrating exposure to semiconductor and AI infrastructure names after a sharp rally.
