How it started

History

CAT was founded in 1989 by Dr. David Chiswell OBE and Sir Greg Winter, with major scientific contributions from Dr. John McCafferty and the Medical Research Council (UK) (MRC). Operations began at the MRC laboratories in Cambridge. In May 1990, operations moved to the Daly Research Laboratories at Babraham Institute, Cambridge.

In 1992, CAT moved to Beech House on the Melbourn Science Park to occupy units B1 and B2. In 1993 the company expanded into unit B3, into B4 into 1995, and in 1998 into units B5, B6, B8 and B9. CAT completed the occupation of Beech House by finally occupying B7 by the late 1990s.

CAT listed on the London Stock Exchange in 1997, raising £43 million, and went through a second round of funding in 2000, raising over £90 million.

In 1999, CAT expanded into a second location in Melbourn called Cambridge House. After leaving Melbourn, CAT sold this location on to housing developers in early 2006.

In 2000, after a succession of deals that focussed on harnessing the exploitation of the human genome, CAT's share price peaked at over £50 per share.
