PROIMMUNE LIMITED
Company number 03873386 · Monitor this company
Executive summary
ProImmune Limited is a niche leader in the immunology research reagents sector, operating from the Oxford Science Park with a 25-year track record and an exceptionally strong balance sheet of £58.6M net assets—far exceeding typical SME life sciences benchmarks. However, the company's capital structure is unusual, with £53.9M held in current asset investments representing 80% of total assets, raising questions about whether accumulated wealth reflects core operational profitability or treasury management. The company's financial resilience and proprietary IP position it well within the growing immunotherapy tools market, though limited public disclosure under the small companies regime constrains full assessment of operational performance against sector norms.
