exclusion reasons

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.
Ionis Pharmaceuticals is a biotechnology company whose research and development of antisense oligonucleotide therapies involves animal testing. The company’s business model is predicated on preclinical studies that require the use of laboratory animals to assess drug safety and efficacy. This record is flagged under the general animal exploitation category, but specific evidence regarding the scale, nature, or recent history of this activity has not yet been gathered and documented.
Excluded under ECIC's animal testing policy. This company conducts or commissions preclinical animal testing as part of its product development program. For pharmaceutical and biotechnology companies, such testing is typically required by FDA regulations as a prerequisite to human clinical trials. This is a policy-based exclusion; company-specific evidence is scheduled for enrichment in Q2/Q3 2026.

The Naughty List
A digest of changes to our exclusion list — new additions, removals, and the evidence behind them. We review the list continuously as new evidence surfaces.
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.
