BrainStorm Cell Therapeutics Announces First Quarter 2026 Financial Results and Provides Corporate Update

• BrainStorm continues its preparations for the Phase 3b ENDURANCE study of NurOwn, with clinical sites on standby and manufacturing and operational activities well underway. The planned study is expected to enroll approximately 200 participants across leading ALS centers and is designed as a two-part trial: a 24-week randomized, double-blind, placebo-controlled segment (Part A) followed by a 24-week open-label extension (Part B) to further characterize long-term safety and durability of effect. The primary efficacy endpoint will measure change from baseline to Week 24 on the ALSFRS-R scale.
• ENDURANCE Part A completion expected to support new BLA submission. Successful completion of Part A of the study is anticipated to generate the clinical data required to support a new Biologics License Application (BLA) submission for NurOwn. Further trial details are posted on ClinicalTrials.gov ID NCT06973629.

Corporate

• In February 2026, the company entered into two strategic private placement agreements, each consisting of stock and warrants, securing a total of $2 million in funding. Together, these financings are expected to reinforce a stable valuation for the company and provide the resources to support near-term operational objectives and preparatory work for the planned Phase 3b ENDURANCE trial of NurOwn. 
• On May 4, 2026, the Company entered into two additional private placement agreements with accredited investors, issuing an aggregate of 210,526 shares of Common Stock at $0.95 per share, together with warrants to purchase up to 252,630 shares of Common Stock at an exercise price of $1.45 per share, generating aggregate gross proceeds of $200,000. The proceeds are intended to support working capital and general corporate purposes.

Financial Results for the Three Months Ended March 31, 2026

• Cash, cash equivalents, and restricted cash were approximately $0.2 million as of March 31, 2026, compared to approximately $0.3 million as of December 31, 2025.
• Research and development expenditures, net, for the three months ended March 31, 2026 were approximately $0.8 million, compared to approximately $1.3 million for the three months ended March 31, 2025.
• General and administrative expenses for the three months ended March 31, 2026 were approximately $1.3 million, compared to approximately $1.8 million for the three months ended March 31, 2025.
• Net loss for the three months ended March 31, 2026 was approximately $2.1 million, as compared to a net loss of approximately $2.9 million for the three months ended March 31, 2025.
• Net loss per share for the three months ended March 31, 2026 and 2025 was $(0.19) and $(0.45), respectively.

About NurOwn®

The NurOwn® technology platform (autologous MSC-NTF cells) represents a promising investigational therapeutic approach to targeting disease pathways important in neurodegenerative disorders. MSC-NTF cells are produced from autologous, bone marrow-derived mesenchymal stem cells (MSCs) that have been expanded and differentiated ex vivo. MSCs are converted into MSC-NTF cells by growing them under patented conditions that induce the cells to secrete high levels of neurotrophic factors (NTFs). Autologous MSC-NTF cells are designed to effectively deliver multiple NTFs and immunomodulatory cytokines directly to the site of damage to elicit a desired biological effect and ultimately slow or stabilize disease progression.

About BrainStorm Cell Therapeutics Inc.

BrainStorm Cell Therapeutics Inc. (OTCQB: BCLI) is a leading developer of autologous adult stem cell therapies for debilitating neurodegenerative diseases. The company's proprietary NurOwn® platform uses autologous mesenchymal stem cells (MSCs) to produce neurotrophic factor-secreting cells (MSC-NTF cells), designed to deliver targeted biological signals that modulate neuroinflammation and promote neuroprotection.

NurOwn® is BrainStorm's lead investigational therapy for amyotrophic lateral sclerosis (ALS) and has received Orphan Drug designation from both the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA). A Phase 3 trial in ALS (NCT03280056) has been completed, and a second Phase 3b trial is set to launch under a Special Protocol Assessment (SPA) agreement with the FDA. The NurOwn clinical program has generated valuable insights into ALS disease biology, including pharmacogenomic response associated with the UNC13A genotype, biomarker data collected at seven longitudinal time points, and a comprehensive analysis of the "Floor Effect" - a critical challenge in measuring clinical outcomes in advanced ALS. BrainStorm has published its findings in multiple peer-reviewed journals. In addition to ALS, BrainStorm has completed a Phase 2 open-label multicenter trial (NCT03799718) of MSC-NTF cells in progressive multiple sclerosis (MS), supported by a grant from the National MS Society. BrainStorm is also advancing a proprietary, allogeneic exosome-based platform designed to deliver therapeutic proteins and nucleic acids. The company recently received a Notice of Allowance from the U.S. Patent and Trademark Office for a foundational patent covering its exosome technology, further strengthening BrainStorm's growing IP portfolio in this emerging area of regenerative medicine.
