Dallas, Tx -- February 10th, 2026 -- AB Science S.A. (ENXTPA: AB): Stonegate Capital Partners Initiates Coverage on AB Science S.A. (ENXTPA: AB). AB Science is a late-stage biotech advancing masitinib, an oral, selective tyrosine kinase inhibitor designed to modulate maladaptive neuroinflammation through mast-cell and microglia/macrophage pathways. The Company is positioning masitinib as an add-on therapy across ALS, progressive MS, and AD, while maintaining earlier-stage upside through AB8939 in AML. The combination of a treatment for ALS along with the optionality that comes with the rest of the Company’s portfolio makes us excited to monitor the development of AB’s Masitinib asset.
