Who owns Immunocore Holdings?

Immunocore Holdings trades in the U.S. through ADRs, certificates that represent shares of a non-U.S. company. Form 13F counts ADRs while the company reports ordinary shares, so we do not compute percentages. Holders reporting more than 5% of the ordinary shares to the SEC (Schedules 13D/13G): Wellington Management Group LLP, 11.6% (13G/A filed Aug 13, 2026), Jallal Bahija, 8.2% (13G filed Feb 14, 2025), Primecap Management, 7.5% (13G/A filed Aug 14, 2025), Bellevue Group, 5.6% (13G filed Nov 14, 2025) and Tang Capital Management, 5.2% (13G filed Oct 24, 2025). As of Jun 30, 2026, the largest ADR holders reported on Form 13F were Wellington Management Group LLP (5.7 million ADRs), RTW Investments (4.9 million ADRs) and FMR (4.3 million ADRs).

From the statements the company filed with the SEC (10-K). The change compares average diluted shares of each fiscal year, on today's basis: negative = it bought back more than it issued; positive = dilution. “No data” = the company does not report that item under a tag we can read; it does not mean zero.

Debt due within 12 months

From the figures the company filed with the SEC. Cash flow over net income near or above 1 means earnings are collected in cash; far below, that part is accounting. Coverage says how many times operating income pays the latest fiscal year's interest. Maturities come from the debt note of the latest annual report, counted from its closing date. “No data” never means zero.
