The rate of pipeline replenishment is one way to understand a company’s sales growth. The replenishment rate shows the ratio of incremental sales from products launched in the last five years to losses in sales from patent expirations over the same time period. That rate is forecast to fall from 2022 through 2026 as industry sales at risk from upcoming patent expirations outweigh sales from new products to be launched.
EY analysis of the replenishment rates of the top 25 biopharma companies by revenue suggests the ratio will drop more than 50%, from 1.6x in 2020 to 0.8x by 2026 (see Figure A). Companies with a ratio of less than 1 are losing more sales due to having more patent expirations than what they are recouping from pipeline products. The forecast innovation deficit comes as these major biopharmas are launching fewer products themselves – and push back from legislators and payers curbs the ability to achieve sales growth through price increases.
This is evident from the fact that big pharma’s new molecular entity (NME) approval rate fell to 49% in 2020 from 77% in 2011, while smaller biotech companies have seen their approval rate rise to 49% from 20% over the same period (Figure B).
