PRESS RELEASE
STONEGATE CAPITAL PARTNERS UPDATES ITS COVERAGE OF AB SCIENCE’S STOCK WITH A DISCOUNTED CASH FLOW VALUATION MID-POINT OF EUR 4.25 PER SHARE
Paris, June 2nd , 2026, 6pm CET
AB Science SA (Euronext - FR0010557264 - AB) announces that its stock continues to be covered by Stonegate Capital Partners, a leading independent US-based research and investor outreach firm, which has updated its coverage of the stock following the publication of AB Science’s full year 2025 results, supported by a discounted cash flow valuation with a mid-point of €4.25 per share (range of €3.20 to €5.77 per share).
Stonegate Capital Partners issued this update in a research note entitled “Stonegate Capital Partners Updates Coverage on AB Science S.A. (ENXTPA: AB) 1Q26”, published on 26 May 2026.
In this update, Stonegate maintained its coverage of the stock, supported by a discounted cash flow model returning a valuation range of €3.20 to €5.77 per share, with a mid-point of €4.25 per share.
The update highlights that :
- AB Science’s strategy now centres on two priorities, masitinib in Amyotrophic Lateral Sclerosis (ALS) and AB8939 in acute myeloid leukemia (AML), reflecting clearer capital allocation. Progressive multiple sclerosis (MS) and Alzheimer’s disease (AD) remain meaningful sources of upside but are now positioned as partnership-led opportunities, given the scale and commercial infrastructure they require.
- Masitinib remains AB Science’s lead clinical asset in ALS. The confirmatory Phase 3 trial AB23005 is FDA-authorized. The 408-patient, 48-week study evaluates masitinib 4.5 mg/kg/day plus riluzole versus placebo plus riluzole, prospectively targeting normally progressing ALS patients without complete loss of function. In this targeted patient population, AB Science reported a 4.04-point ALSFRS-R benefit, a +20.2% relative CAFS benefit, a 9-month median progression-free survival benefit and a 12-month median overall survival benefit, alongside the identification of a potential plasma biomarker tied to microglia and mast-cell activity.
- AB8939 is emerging as a visible second pillar, having completed Stage 3 of the AML combination programme (14 days of AB8939 plus venetoclax), with Stage 4 expected to add azacitidine subject to regulatory approval. Early data showed responses in all four treated patients, including one complete remission, one near-complete response and two partial responses, in heavily pre-treated patients with difficult cytogenetics. While still early, these data support continued development in AML populations where resistance and unfavourable genetics remain major unmet needs.
- On the financing side, AB Science ended FY2025 with €10.2M in cash and added €3.2M through an April 2026 private placement, while its operating loss excluding non-recurring items declined 38% to €3.8M, with creditor deferrals helping to preserve cash for R&D. The Company received a clinical trial financial insurance (CTFI) offer for AB23005, with excess-free coverage of €25M, extendable to €39M, intended to cover clinical-failure costs and provide third-party validation of the Phase 3 design, subject to study funding and premium payment.
- Stonegate values AB Science using a discounted cash flow model, returning a valuation range of €3.20 to €5.77 per share, with a mid-point of €4.25 per share. Stonegate notes that this framework is currently conservative and that a reduction in the discount rate to approximately 15%, which could be warranted following successful regulatory and operational de-risking, would imply a valuation mid-point of approximately €8.50 per share.
This update confirms Stonegate Capital Partners’ coverage of AB Science’s stock, which adds to the financial analyst consensus alongside Maxim Group, Chardan, In Extenso Finance and DNA Finance.
