Pfizer Chief Executive Albert Bourla is battling impending expirations for some blockbuster-drug patents and the precipitous decline of the company's Covid franchise, but he has put a date on when the company will return to consistent growth: 2029. Bourla said Tuesday he expects Pfizer will post high-single-digit average revenue growth annually from 2029 through 2033. “Products are losing patents, and we have a clear line of sight on growth starting in '29,” Bourla said in an interview after the company reported better-than-expected first-quarter results.
