2 POLYMER FACTORY SWEDEN AB | INTERIM REPORT, Q2 2026 2 Strengthening our commercial position The second quarter was characterized by continued strong interest in Polymer Factory's products from leading international organizations. During the quarter, we initiated several commercial collaborations with multinational companies that recognize the significant value our technologies can deliver to their customers. Although the global market continues to be affected by geopolitical uncertainty, macroeconomic challenges and cautious investment decisions, we are seeing encouraging momentum in our commercial discussions. Strategic collaborations driving future growth A major achievement during the quarter was the initiation of a strategic collaboration with Thermo Fisher Scientific in the United States regarding our innovative SpheriCal® technology. Thermo Fisher Scientific recognizes the commercial potential of our calibration products for enabling new applications in advanced multidimensional mass spectrometry. In addition, several other multinational companies have expressed strong interest in the same technology area, reinforcing our confidence in the long-term commercial potential of SpheriCal®. Global customers validate our technology Our Dendrimers & Dendrons business continues to develop positively. During the quarter, Polymer Factory supplied products to several leading international companies and world-renowned academic institutions. Customers included GSK, Ascendis Pharma, Merck, STEMCELL Technologies, the Massachusetts Institute of Technology (MIT) and Princeton University. The continued confidence shown by these organizations demonstrates the quality, performance and competitiveness of our technologies and products. COMMENTS FROM CEO MATS WALLNÉR COMMENTS FROM CEO Promising progress in drug delivery research Development of our Dendritic Nanogels (DNG) continues to demonstrate significant potential as advanced drug delivery systems for difficult-to-treat cancers, including glioblastoma and triple-negative breast cancer. Results from the collaborative research published in 2025 demonstrated promising performance of our patented bis-MPA dendritic nanotechnology, including high drug-loading capacity, efficient tumor penetration and significant inhibition of cancer cell growth in laboratory studies. During the second half of 2026, the research team plans to repeat the laboratory studies to further validate these encouraging results and support the next stages of development. Well positioned for the future Polymer Factory is built on decades of world-class research and expertise in dendritic materials and advanced polymer technologies. Today, we are supplying products to some of the world's leading companies and research institutions while continuing to expand our commercial opportunities through strategic partnerships and product innovation. MATS WALLNÉR CEO The second quarter was characterized by continued strong interest in Polymer Factory's products from leading international organizations ” Well positioned to create long- term value for our customers, partners and shareholders” Mats Wallnér, CEO of Polymer Factory

3 POLYMER FACTORY SWEDEN AB | INTERIM REPORT, Q2 2026 ABOUT POLYMER FACTORY Polymer Factory is a leading developer and provider of dendritic nanomaterials, to be applied over a range of sectors globally. Polymer Factory is in many ways an accelerator firm for dendritic nanotechnology – generating cutting-edge products desired by customers across different high-demand sectors. From our roots in dendritic materials, we have developed SpheriCal®, a pioneering calibration technology for mass spectrometry (MS), and more recently, our latest addition, DNGs. Our broad portfolio, comprising more than 300 products, has attracted customers from BigPharma, MedTech, BioTech, as well as the chemical and other industries. Stemming from many years of cutting-edge research, Polymer Factory was founded by a team of well-renowned scientists. This research has evolved into a business that provides products to billion dollar industries. MISSION To provide life science customers with premium precision nanomaterials for improved analysis and performance. VISION By providing nanomaterials, enable the development of products that improve life and prosperity. What makes dendritic materials so special, and in many ways superior, is their flawlessness, multifunctionality and dynamic structure. This makes them ideal for a vast number of applications in an array of industrial uses, from applications within pharmaceuticals and diagnostics as well as the chemistry and material industries. Polymer Factory’s dendritic materials have a number of competitive advantages: • Structural perfection (i.e. they are monodisperse and structurally flawless). • High scalability and batch-to-batch consistency – an important feature across several high-end sectors e.g. therapeutic and diagnostic applications. • High loading capacity, enabling the attachment of an exact and large number of drugs while decreasing the drug’s toxicity when merged with the dendritic material. • High level of optimization and flexibility, allowing users to achieve desired targeted complexation and product formulation. • Biocompatibility and biodegradability; the dendritic carriers degrade under physiological conditions.
