BiomX shares surge 72.20% after-hours after Pyu Pyu Capital acquires 19.99% stake via 13D filing.

BiomX surged 72.20% in after-hours trading following a 13D filing disclosing Pyu Pyu Capital’s acquisition of a 19.99% stake in the company. The filing, which signals a significant investor commitment, triggered heightened market speculation about strategic initiatives or value-creating actions. While BiomX issued statements clarifying no undisclosed developments, the new stake by Pyu Pyu Capital—often interpreted as a vote of confidence in the biotech’s phage therapy platform—directly drove the sharp price increase. The move reflects market optimism about potential governance influence, operational changes, or partnership opportunities tied to the substantial ownership position.
