“If you think about first half, second half, we have the annualization impact given the mid-year step-up in rebates last year. So the annualization impact comes through in the first half, you'd expect price erosion to be greater in the first half or the second half.”

In context

“gnificant majority of Humira will see it at parity lives in '24. Okay. So the tail we're going to be negotiating '25. And what we've highlighted is we are going to watch exactly how the interchangeables play out. We think we've got a good understanding of that. And so it will probably become more apparent as we move through '25 where that tail may sit. And we've highlighted that it may start to emerge in '25 and probably be much more visible by '26. And that's going to ultimately depend on how over the course of '25, the price volume fully plays out in the marketplace. Robert Michael : And Chris, this is Rob. On your question regarding the guidance for this year. I think it's important to note yes, we've said that the vast majority of the erosion is price. We've talked about that dynamic. If you think about first half, second half, we have the annualization impact given the mid-year step-up in rebates last year. So the annualization impact comes through in the first half, you'd expect price erosion to be greater in the first half or the second half. But at the same time, we did contemplate volume erosion because we were very well aware of the CVS contract. We gave you that guidance. And so we have contemplated that volume erosion, but that's more of a second half versus first half as well as the potential for we knew with an interchangeable coming in, there could be some marginal amount of volume pickup there. So we did put in volume erosion in our guidance, but the vast majority of it is price, but I don't want investors to think that we didn't put any volume into our guidance. We were very well aware of the CVS contract. And I think we made some prudent assumptions on potentially other impacts. But overall, we're still tracking in line with that guidance.
