After his latest acquisition, Duggan’s ownership in Summit Therapeutics now stands at 573.88 million shares. This represents a substantial holding in the company, which has a total market value, or market capitalization, of approximately $10.45 billion. This large stake demonstrates a strong alignment between the executive's interests and the company's long-term success and growth trajectory.
