Instil Bio is a clinical-stage biotechnology company that tries to develop cancer treatments using a type of immune cell called tumor-infiltrating lymphocytes, or TILs. These are cells taken from a patient's own tumor, grown in large numbers in a lab, and then put back into the patient to fight the cancer. The company focuses on solid tumor cancers, and its main customers would be cancer patients and the hospitals or clinics that treat them.

Instil Bio makes no product revenue yet because its treatments are still being tested in clinical trials and none have received regulatory approval. The company is based in the United States and has built its own large-scale cell therapy manufacturing facilities, which it once planned to use for other drugmakers as well. With a tiny market cap and deeply negative returns on capital, the biggest risk the company faces is running out of cash before it can prove its treatments work well enough to win approval.

The Winston Score above measures business quality today. Growth stocks often score lower because they invest in the future rather than maximising current profits. These metrics show what matters most for evaluating that future.
