Key data presentations for the PRAME franchise and HIV program are also slated for the second half of 2026, and the first autoimmune candidate is expected to enter Phase 1 trials in the first half of 2026.

Management Comments

• "With $400 million in KIMMTRAK sales and a diverse clinical portfolio, Immunocore had a productive year of growth and progress in 2025."

Industry Context

StockSavvy.ai notes that Immunocore's continued growth in KIMMTRAK sales, particularly its strong European expansion, positions it well within the competitive oncology market for uveal melanoma. The company's strategic pipeline diversification into advanced cutaneous melanoma, infectious diseases (HIV), and autoimmune diseases reflects a broader industry trend towards leveraging core technology platforms for multiple therapeutic applications, aiming to de-risk and expand market opportunities beyond initial indications.

Comparison to Industry Standards

• KIMMTRAK's 29% year-over-year sales growth for FY 2025 ($400.0 million) demonstrates strong commercial execution, particularly in a rare disease market like metastatic uveal melanoma, where it has become the standard of care. This growth rate is competitive with successful orphan drug launches in the biotechnology sector.
• The increase in R&D expenses to $274.9 million for FY 2025, driven by multiple Phase 3 trials (TEBE-AM, PRISM-MEL-301) and preclinical autoimmune programs, is typical for a commercial-stage biotechnology company actively expanding its pipeline and pursuing lifecycle management for its lead product. This level of investment is comparable to peers like Regeneron Pharmaceuticals or Incyte Corporation at similar stages of pipeline maturity and commercialization efforts.
• The strong cash position of $864.2 million as of December 31, 2025, provides significant runway, exceeding the typical 12-18 months of cash required by many clinical-stage biotechs, offering substantial financial flexibility for ongoing and planned clinical programs without immediate need for dilutive financing.
• The anticipated completion of TEBE-AM enrollment in 1H 2026 and topline data in 2H 2026 for a registrational Phase 3 trial aligns with industry timelines for late-stage clinical development, demonstrating efficient trial execution for a complex oncology indication.

Stakeholder Impact

• Shareholders: Positive impact due to strong revenue growth, improved net loss, robust cash position, and significant pipeline progress, which could drive future value.
• Patients: Positive impact through continued access to KIMMTRAK for uveal melanoma and potential new therapies for advanced cutaneous melanoma, HIV, and autoimmune diseases from the advancing pipeline.
• Employees: Continued growth and pipeline expansion suggest stability and potential for further opportunities within the company.
• Creditors: Strong cash position and improving financial performance enhance the company's creditworthiness.

Next Steps

• Complete enrollment for the TEBE-AM registrational Phase 3 trial in the first half of 2026.
• Present topline overall survival (OS) data for the TEBE-AM trial as early as the second half of 2026.
• Present Phase 1/2 data for brenetafusp (ovarian and NSCLC) and initial data for IMC-P115C (half-life extended PRAME-A02 candidate) in the second half of 2026.
• Present additional Phase 1 HIV data in the second half of 2026.
• Begin the Phase 1 trial for IMC-S118AI (PPI x PD1) in autoimmune disease in the first half of 2026.
• File a CTA or IND application for IMC-U120AI (CD1a x PD1) in autoimmune disease in the second half of 2026.
• Present initial data for IMC-R117C (PIWIL1) in colorectal and other gastrointestinal cancers in 2027.
• Continue to expand patient reach for KIMMTRAK in metastatic uveal melanoma, second-line plus advanced cutaneous melanoma, and adjuvant uveal melanoma.
