"What we've said is that by 2021 we would cover the dividend in full and we would target an operating margin north of 30%.

This is very much in line with what we are targeting," CEO Pascal Soriot said, following the release of fourth-quarter results.

AstraZeneca is moving into a third year of sales growth after changes driven by Soriot and now has nine drugs with annual sales of more than $1 billion but analysts and investors have been looking for clues whether the company's earnings growth would keep up.

The company's 2019 operating margin, or earnings before interest and tax over total revenue, was 26%.
