NEW YORK, Sept. 02, 2026 (GLOBE NEWSWIRE) -- SL Science Holding Limited (“SL Science” or the “Company”) (NASDAQ: SLBT), a Taiwan-headquartered biomedical company specializing in developing innovative cellular and gene therapies, today announced that its management team rang Nasdaq bell at the Nasdaq MarketSite in Times Square, New York, to celebrate its first quarter as a publicly traded company. The ceremony marked the Company’s first appearance at Nasdaq since completing its business combination with Horizon Space Acquisition II Corp. and commencing trading under the ticker symbol “SLBT” on June 15, 2026. It also closes out SL Science's first quarter as a public company, a period during which the Company advanced its Gamma Delta (γδ) T cell platform across scientific, academic, and regulatory fronts. From Listing to Execution: Progress Since June 15, 2026 SL Science reached key strategic milestones this quarter to support its clinical development trajectory, led by its ongoing Orphan Drug Designation (ODD) request for Vdelta2+ γδT cells in glioblastoma multiforme (DRU-2026-11528) under the U.S. Food and Drug Administration (FDA) review since March 2026, with the Company currently preparing additional nonclinical data requested by the agency. Building on this regulatory momentum, preclinical research jointly conducted with research partners on intracranial γδT cell therapy in glioblastoma models was exhibited in July 2026 at the World Congress of Basic and Clinical Pharmacology in Melbourne, Australia. These advancements are powered by SL Science’s γδT cell platform, licensed from IP holder JY BioMed for brain and pancreatic cancer indications. Operating independently of major histocompatibility complex (MHC) presentation, γδT cells directly engage tumor cells to bypass immune evasion and tumor heterogeneity, offering a scalable cell population that complements modalities like mRNA therapies and checkpoint inhibitors. To support commercialization, Drug Master Files (DMFs) covering both γδT cells and γδT-derived exosomes are filed with the FDA, providing confidential quality and manufacturing data that establish a documented Chemistry, Manufacturing, and Controls (CMC) foundation across both product formats. Management Commentary “Ringing the bell at Nasdaq is a moment worth marking, but what matters is what we have done with the eleven weeks since we started trading,” said Mr. William Wang, Chairman and Chief Executive Officer of SL Science.“We have continued to advance our scientific and development efforts while building the foundation for the next stage of growth. We believe the future of cancer treatment will increasingly involve complementary approaches. γδ T cells have the potential to play an important role alongside advances such as mRNA-based cancer vaccines and checkpoint inhibitors. We believe these approaches have the potential to open new possibilities in cancer treatment. Standing here at Nasdaq today is a marker on that path, not the destination.” About SL Science Holding Limited SL Science Holding Limited is a biomedical company specializing in developing innovative cellular and gene therapies.

Taipei, TAIWAN, June 18, 2026 (GLOBE NEWSWIRE) --  SL Science Holding Limited (“SL Science” or the “Company”) (Nasdaq: SLBT), a Taiwan-headquartered biomedical company specializing in developing innovative cellular and gene therapies, today announced its financial results for the full year ended December 31, 2025. Management Commentary "2025 was a highly transformative and foundational year for SL Science as we aggressively advanced our core cell therapy pipeline and executed our long-term strategic shift toward next-generation immunotherapies. Throughout the past year, we strategically prioritized our resources on high-value clinical research and development, committing over $2.07 million to expand our proprietary cell platforms. This includes advancing our off-the-shelf Gamma Delta T (GDT) cell culture platforms, which is ready-to-use treatments to target significant unmet medical needs in blood, pancreatic, and brain cancers with scalable manufacturing and reduced cost. As part of this transition, we restructured our commercial model, shifting from direct retail sales to corporate distribution channels in Asia. While this structural pivot temporarily impacted our top-line revenue, it effectively freed up operational bandwidth to drive our therapeutic programs forward," said Mr. William Wang, Chairman and Chief Executive Officer of SL Science. “We entered 2026 with tremendous momentum, culminating in the recently announced completion of our business combination and successful listing on the Nasdaq Global Market. This milestone, combined with our concurrent $7.8 million PIPE financing, provides the enhanced financial flexibility necessary to accelerate our growth strategy. It positions us to attract top-tier global scientific talent, facilitate potential future strategic acquisitions, and firmly support our near-term clinical operating requirements.” “Looking ahead, with the vision of establishing one of the leading allogeneic Gamma Delta T cell platforms in Asia with global commercialization potential, our focus is squarely on regulatory preparedness and preclinical execution. For our CD-19 Armed-T blood cancer program, we are actively addressing the FDA’s initial feedback by conducting additional nonclinical validation and manufacturing scale-ups, aiming for a Pre-Investigational New Drug (IND) meeting and formal IND submission in the first quarter of 2027. Concurrently, our Unmodified GDT cell platform is progressing through technical transfers to an FDA-compliant contract development and manufacturing organization (CDMO). Unlike traditional autologous therapies, our GDT cell approach is designed to create scalable, ready-to-use treatments, aiming to address the high costs and production delays currently facing the oncology market. Our ultimate vision is to establish SL Science as a global clinical leader, optimizing patient outcomes through breakthrough cellular innovations.” SL Science's Full Year 2025 Financial Results Through the Company’s proprietary cell expansion, bispecific antibody engineering platforms, and legacy exosome commercial operations, SL Science is building a clinically driven oncology model designed to capture expansion within the multi-billion-dollar solid tumor therapeutics market. The following table presents selected summarized financial information derived from the Company's consolidated statements of operations for the years ended December 31, 2025 and 2024. Net Revenue Net revenue decreased by approximately $1.17 million, or 35%, to approximately $2.20 million for the year ended December 31, 2025, compared to approximately $3.36 million for the year ended December 31, 2024. The decrease was primarily driven by the planned business transformation of the Company's Taiwan operations, which transitioned from high-frequency direct individual end-users and corporate customers retail sales of exosome concentrate products toward a wholesale model with corporate distributors. This strategic shift allowed the Company to focus more on research and development programs and redeploy infrastructure to its clinical assets, resulting in lower margin from wholesales as well as a lower volume frequency during the interim adjustment period. The Company operates in three segments: Exosome products, CD-19 Armed-T products and GDT Cell Therapy products. The net revenue represented the sales of Exosome products only. There was no revenue generated and assets allocated for the CD-19 Armed-T products and GDT cell therapy products segments for the year ended December 31, 2025. Cost of Revenue Cost of revenue decreased slightly by approximately $0.01 million, or 1%, to approximately $1.42 million for the year ended December 31, 2025, compared to approximately $1.43 million for the year ended December 31, 2024. Cost of revenue consists primarily of product procurement for resale. The variance relative to the revenue decline reflects an increased share of lower-margin corporate wholesale volumes during the year ended December 31, 2025. Gross Profit Gross profit decreased by 60% to approximately $0.78 million for the year ended December 31, 2025, compared to approximately $1.93 million for the prior year period, impacted by the structural wholesale transition and product mix revisions. Operating Expenses Total operating expenses increased by approximately $1.48 million, or 47%, to approximately $4.61 million for the year ended December 31, 2025, compared to approximately $3.13 million for the year ended December 31, 2024. The increase was primarily driven by a 123% expansion in general and administrative expenses due to management team expansion and approximately a $1.16 million, or 529%, increase in office salaries. Research and development expenses remained robust at approximately $2.07 million, supporting parallel asset validation for the Company’s CD-19 Armed-T products and GDT cell therapy products during the year ended December 31, 2025. Net Loss Net loss for the year ended December 31, 2025 was approximately $3.82 million, compared to a net loss of approximately $1.19 million for the year ended December 31, 2024, resulting from the combination of adjusted wholesale revenues and expanded administrative infrastructure costs. Cash, Cash Equivalents and Restricted Cash As of December 31, 2025, SL Science's restricted and unrestricted cash balances stood at approximately $1.26 million compared to approximately $4.14 million as of December 31, 2024. The change was driven primarily by approximately $1.91 million utilized in operating activities and approximately $0.88 million in deferred offering costs related to the public listing process.
