This page is part of our public exclusion list — a transparency tool that shows which companies we screen out and why. It is not investment advice, and it is not an accusation. But it is subject to change as our understanding of the facts evolves.

Animal Testing & Research
Since Jan 3, 2022

Merus N.V. is a biotechnology company whose core business model involves the development of therapeutic antibodies using genetically engineered mice. The company’s proprietary Biclonics® platform relies on the use of the HuMab-Mouse®, a transgenic mouse platform where mice are genetically modified to produce human antibodies. This process inherently involves the breeding, housing, and experimental use of large numbers of laboratory mice. The company’s research and development activities are fundamentally dependent on animal testing at scale.

Companies appear on our exclusion list based on our investment judgment — not because they've done anything illegal. This is a difference of values and opinion, not an accusation of wrongdoing. Exclusion does not constitute a recommendation against investing in any company, and absence from the list does not constitute a recommendation to invest.

This information is provided for educational and transparency purposes only and should not be relied upon as investment advice. Data is drawn from independent watchdogs, NGOs, government registries, and Ethical Capital's ongoing research — see Research Sources for the full list.
