Forget the FDA Delay: 3 Reasons Exelixis Is Still a Buy
Exelixis (EXEL) shares rose 49% this year, but the FDA extended its review of zanzalintinib, a colorectal cancer drug, to 2027. Despite this, the company highlights three growth drivers: Cabometyx's patent protection until 2030, zanzalintinib's potential $4.5B sales by 2033, and a deep pipeline of oncology drugs. Q2 revenue increased 10.6% to $628.7M, with EPS up 26% to $0.82.
