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.","website":"https://www.proimmune.com/","links":{"page":"https://www.companiesintheuk.co.uk/ltd/proimmune","people":"https://www.companiesintheuk.co.uk/company/proimmune/people","filing_history":"https://www.companiesintheuk.co.uk/company/proimmune/filing-history","companies_house":"https://find-and-update.company-information.service.gov.uk/company/03873386","financials":"https://www.companiesintheuk.co.uk/company/proimmune/financial","control":"https://www.companiesintheuk.co.uk/company/proimmune/control","charges":"https://www.companiesintheuk.co.uk/company/proimmune/charges","ai_analysis":"https://www.companiesintheuk.co.uk/company/proimmune/analysis"},"source":"CompaniesInTheUK, from Companies House, The Gazette and other public registers (see /support/about).
