Is Vertex a Biotech or Pharma?

Could you please clarify for me whether Vertex should be classified as a biotechnology company or a pharmaceutical company? I understand that they are involved in developing treatments for various medical conditions, but I'm unsure if they focus more on the research and development side, which would make them a biotech, or if they produce and distribute drugs, which would categorize them as a pharma company. Any insight you could provide would be greatly appreciated.
