BlockBeats news, June 3: "New Stock God" Serenity compares two semiconductor companies from European and U.S. markets. POET, listed on Nasdaq, has a market capitalization of approximately $2.4 billion and specializes in packaging Sivers lasers, currently holding only one $50 million pre-production contract with warrants. In contrast, X-FAB (XFAB), listed in Europe, has a market capitalization of just $1.7 billion yet possesses core assets far exceeding its valuation—it is one of the few global foundries to receive funding under both the EU CHIPS Act and the U.S. CHIPS Act for SiC/GaN/MEMS/silicon photonics, and its current valuation is even below its replacement cost book value.
Serenity further highlights XFAB’s differentiating advantages: NVIDIA and Nokia are currently evaluating its pre-production silicon photonics foundry line, with volume ramp-up expected between 2027 and 2028; as a foundry, XFAB is leading the large-scale expansion of Europe’s photonics supply chain through deep collaborations with key European photonics institutions such as IMEC, CEA-Leti, Ligentec, and Smart Photonics; its customer base includes Navitas Semiconductor, Power Integrations, and Lite-On. Serenity specifically cites the U.S. Department of Commerce’s official characterization—“XFAB is the only high-volume silicon carbide foundry in the United States”—underscoring its scarce strategic value amid trade barriers and the trend toward supply chain localization.
XFAB's U.S. stock ticker is XFABF; it is a Belgian company, X-FAB Silicon Foundries SE, primarily listed on the Euronext Paris exchange under the ticker XFAB (traded in euros).
