Shares of X-Fab Silicon Foundries SE (OTC: XFABF) climbed 55.6% on Wednesday after a social media account known for semiconductor analysis identified the company as an investment opportunity.
The post came from Serenity, an online account that characterizes itself as an AI and semiconductor supply chain analyst. Serenity emphasized X-Fab’s positions in power semiconductors and silicon photonics and pointed to government support via both the EU and US CHIPS acts as part of the investment case.
X-Fab is a foundry that specializes in mature process nodes and runs three manufacturing plants in Germany. The company has received 128 million euros from the EU CHIPS act and $50 million from the US CHIPS act, amounts highlighted in the social media analysis.
The social media note also drew attention to X-Fab’s commercial links in power semiconductors and silicon photonics, including suggested relevance to data center and AI infrastructure supply chains. Serenity referenced a price-to-book ratio for X-Fab of roughly 1.29 and described the stock as appearing undervalued based on that metric.
Following trading in the session, X-Fab’s market capitalization stood at about $1.78 billion. That figure comes after the company’s shares have risen roughly 200% over the last six months. The firm conducts its silicon photonics activities under the name "photonixFAB."
Market observers noted that the price move seems to have been driven primarily by retail investor interest in the wake of the social media post, rather than by new company-specific developments, earnings, or operational announcements from X-Fab itself.
Investors and market participants should interpret the stock’s sharp intraday gain in the context of the information cited in the social media post - exposure to power semiconductors and silicon photonics, and direct funding under the EU and US CHIPS acts - while recognizing the absence of fresh public disclosures or financial results tied to the price move.
